However, the effects of OMT following initial treatment have not been reported. Objective: To determine the effects of OMT for patients with chronic non-specific back pain in a rural safety-net hospital setting for an initial post-clinical and follow-up visit. Methods: A longitudinal, rolling admission, eleven-year study of cohort study with a primary complaint of chronic, non-specific back pain that had plateaued in improvement for a minimum of six months. One hundred and fifty-one subjects completed the first two study visits necessary for data collection, and fifty-nine subjects completed the follow-up visit after six months. Results: A two-way, mixed model, repeated measures ANOVA with pre- post1 and post2 (follow-up) treatment as the within variable and sex as the between subject variable showed a significant main effect from pre- to follow-up, (F (1, 57) = 21.171, P ηP2= 0.426), but not a significant interaction between time and sex (F (1, 57) = 0.279, P ηP2= 0.002). Conclusions: The results of this study support the hypothesis that OMT has a continued benefit in pain reduction and functional improvement beyond the initial treatment period. The rural, safety-net hospital setting made this study unique relative to the sample population.展开更多

The reduced value for morphologically normal spermatozoa over the years may be due to several factors. The first is the introduction of strict criteria for the evaluation of sperm morphology. Other reasons may include the introduction of additional criteria for sperm morphology abnormalities and the suggested decrease in semen parameters because of increasing negative environmental influences. Although on its own the newly proposed very low normal value may not provide the strong predictive value for a males' fertility potential, as originally reported for sperm morphology evaluated according to strict criteria, a good predictive value can still be obtained if the holistic, strict approach for sperm morphology evaluation is followed together with additional sperm morphology parameters now available, because certain morphology patterns and sperm abnormalities are now known to be of strong prognostic value. In addition, better international standardization of the technical methodology, consensus on the interpretation of sperm morphology evaluation criteria and standardized international external quality control (EQC) schemes, are of utmost importance to maintain the good predictive value of sperm morphology.展开更多

Detail analysi...S The methane emission flux from rice paddies was simultaneously measured with automatic and manual methods in the suburban of Suzhou. Both methods were based on the static chamber/GC-FID techniques. Detail analysis of the experimental results indicates: a) The data of methane emission measured with the automatic method is reliable. b) About 11 or 19 o′clock of local time is recommended as the optimum sampling time for the manual spot measurement of methane emission from rice paddies. The methane emission fluxes measured by manual sampling at local time other than the optimum time have to be corrected. The correction coefficient may be determined by automatic and continuous measurement. c) In order to get a more accurate result, an empirical correction factor, such as 18%, is recommended to correct the seasonally total amount of measured methane emission by enlarging the automatically measured data or reducing the manually measured ones.展开更多

Most TPVs stay on the TP, but a small number can move off the TP to the east. TPVs are known to be one of the main precipitation-bearing systems on the TP and moving-off TPVs have been associated with heavy precipitation and flooding downstream of the TP (e.g., in Sichuan province or over the Yangtze River Valley). Identifying and tracking TPVs is difficult because of their comparatively small horizontal extent (400-800 kin) and the limited availability of soundings over the TP, which in turn constitutes a challenge for short-term predictions of TPV-related impacts and for the climatological study of TPVs. In this study, (i) manual tracking (MT) results using radiosonde data from a network over and downstream of the TP are compared with (ii) results obtained by an automated tracking (AT) algorithm applied to ERA-Interim data. Ten MT-TPV cases are selected based on method (i) and matched to and compared with the corresponding AT-TPVs identified with method (ii). Conversely, ten AT-TPVs are selected and compared with the corresponding MT-TPVs. In general, the comparison shows good results in cases where the underlying data are in good agreement, but considerable differences are also seen in some cases and explained in terms of differences in the tracking methods, data availability/coverage and disagreement between sounding and ERA-Interim data. Recommendations are given for future efforts in TPV detection and tracking, including in an operational weather forecasting context.展开更多

In this manner patients have, for example, only been partially treated, been poorly or incorrectly diagnosed, and have been denied the full benefit of compensation for their injuries. This paper contains a proposal for diagnostic criteria particularly for the neuropsychological aspects of the post injury syndrome. It pays attention to widely published consistent descriptions of the syndrome, and a new cluster analysis of post electrical injury patients. It formulates a proposal which could be incorporated into future editions of the American Psychiatric Association's Diagnostic and Statistical Manual (DSM). The major neuropsycholog- ical consequences include neurocognitive dysfunction, and memory subgroup dysfunction, with ongoing consequences, and sometimes including progressive or delayed psychiatric, cognitive, and/or neurological symptoms. The proposed diagnostic criteria insist on a demonstrated context for the injury, both specifying the shock circumstance, and also physical consequences. It allows for a certain delay in onset of symptoms. It recognizes exclusory conditions. The outcome is a proposal for a DSM classification for the post electrical or lightning injury syndrome. This proposal is considered important for grounding patient treatment, and for further treatment trials. Options for treatment in electrical or lightning injury are summarised, and future trials are foreshadowed.展开更多

Methods Twenty five eligible randomized controlled trials were included to compare the use of thrombus aspiration (TA) with PCI and PCI-only for STEMI. The primary endpoint was all-cause mortality and death. The secondary endpoints were major adverse cardiac events (MACE), recurrent infarction (RI), target vessel revascularization (TVR), stent thrombosis (ST), perfusion surrogate markers and stroke. Results TIMI flow grade 3 and MBG 2-3 were significantly increased in the TA plus PCI arm compared with the PCI-only arm [relative risk (RR): 1.05, 95% confidence intervals (CI): 1.02-1.09, P = 0.004] and (RR: 1.68, 95% CI: 1.40-2.00, P 〈 0.001), respectively. There were no significant differences in all-cause mortal- ity, MACEs, TVR and ST rates between the two groups. The RI rate was lower in the TA plus PCI arm than that in the PCI-only arm with short-term follow-up duration (RR: 0.60, 95% CI: 0.38-0.96, P = 0.03), but there was no significant difference in RI incidence over the me- diumor long-term follow-up periods (RR: 1.00, 95% CI: 0.77-1.29, P = 0.98), and (RR: 0.96, 95% CI: 0.81-1.15, P = 0.69), respectively. There were statistically significant differences in the rates of crude stroke and stroke over the medium- or long-term follow-up periods and the crude stroke rate in the TA plus PCI (RR: 1.60, 95% CI: 1.08-2.38, P = 0.02) and (RR: 1.43, 95% CI: 1.03-1.98, P = 0.03), respectively; this was not observed between the two arms during the short-term follow-up period (RR: 1.47, 95% CI: 0.97-2.21, P = 0.07). Conclusions Routine TA-assisted PCI in STEMI patients can improve myocardial reperfusion and get limited benefits related to the clinical endpoints, which may be associated with stroke risk.展开更多

For each lift, the surface electromyography signals from the erector spinae muscles, bilaterally at T_~10 and L_3, was recorded. The ergonomic risk factors associated with manual lifting tasks were evaluated by comparing the average amplitude of EMG signals from the erector spinae muscles. The EMG average amplitude for lifting the load of 13 kg was 14.3 % greater than that for lifting the load of 6 kg (t=-10.93, P<0.01). The EMG average amplitude at the site of L_3 was 10.3 % greater than that at the site of T_~10 (t=-7.98, P<0.01). The EMG average amplitude when performing “fast” lift was 5.9 %greater than the “slow” lift (t=-4.63, P<0.01). The posture of lifting affected the EMG average amplitude. It was lowest with semi-squat posture and greatest with squat posture (F=27.76, P<0.01). The result of multiple stepwise regression analysis showed that the loads of lifting, the size of box, horizontal distance, posture of lifting, the site of the spine subjected to force, lifting speed were the factors affecting the EMG average amplitude. The most significant factor was the loads of lifting, followed by the site of the spine subjected to force and the lifting speed in terms of risk. The ergonomic risk factors associated with manual lifting tasks includes the loads, posture, lifting speed, horizontal distance, the site of the spine subjected to force etc. The results of signal amplitude of EMG from the erector spinae muscles showed that semi-squat posture is the best posture for lifting tasks.展开更多

METHODS: Patients with megalgia caused by CSR were divided into a treatment group (n=46) treated by extradural injection and manual repositioning of the spine and a control group (n=46) treated by a conventional method. RESULTS: The prevalence of cure was 58.69% and the total prevalence of effective cure in the treatment group was 97.83% and was 23.91% and 78.26%, respectively, in the control group: this difference between the two groups was significant (P〈 0.05). CONCLUSION: Treatment of megalgia caused by CSR by extradural injections and manual repositioning of the spine has a good curative effect with rapid analgesia and short therapeutic course.展开更多

Patientstreated with TA had less prevalence of multivessel disease(39.7% vs 54.7%, P = 0.003) and higher prevalence of initial thrombolysis in myocardial infarction flow 【 3(P 【 0.001) than NTA group. There was a higher rate of direct stenting(58.7% vs 45.5%, P = 0.009), with shorter(24.1 ± 11.8 mm vs 26.9 ± 15.7 mm, P = 0.038) and larger stents(3.17 ± 0.43 mm vs 2.93 ± 0.44 mm, P 【 0.001) in the TA group as compared to NTA group. The number of implanted stents(1.3 ± 0.67 vs 1.5 ± 0.84, P = 0.009) was also lower in TA group. CONCLUSION: In an “all-comers” STEMI population, the use of TA resulted in more efficient procedure leading to the implantation of less number of stents per lesion of shorter lengths and larger sizes.展开更多

However, there are few reports addressing changes in neurotransmitter expression following manual acupuncture and electroacupuncture against visceral traction pain.OBJECTIVE: To explore changes in neurotransmitter expression in the ileum and protein expression in the medullary visceral zone of visceral traction pain rats undergoing pretreatment of emulational manual acupuncture, and to investigate the differences between emulational manual acupuncture and electroacupuncture.DESIGN, TIME AND SETTING: The randomized, controlled study was performed at the Biomedical Engineering Laboratory, Shanghai University of Traditional Chinese Medicine, Shanghai, China from August 2008 to July 2009.MATERIALS: G6805 electroacupuncture apparatus (Shanghai Medical Electronic Machine Factory, China) and ZSF-I acupuncture manipulation simulation therapeutic system (Chinese Medical Engineering Room, Shanghai University of Traditional Chinese Medicine, Shanghai China) were used in the present study.METHODS: A total of 40 male Sprague Dawley rats were equally and randomly assigned to sham surgery, model, emulational manual acupuncture and electroacupuncture groups. In the emulational manual acupuncture and electroacupuncture groups, emulational manual acupuncture and electroacupuncture were applied at bilateral Zusanli (ST 36) acupoints for 30 minutes, and models of visceral traction pain were established immediately.MAIN OUTCOME MEASURES: Substance P expression, c-Fos and glial fibrillary acidic protein expression were measured using immunohistochemistry. Acetylcholine esterase activity was examined utilizing a colorimetric method. Leucine-enkephalin content was detected using a radioimmune assay. Degree of pain in rats was assessed by pain score.RESULTS: Pain score, substance P expression in the ileum, acetylcholine esterase activity, expression of c-Fos protein and glial fibrillary acidic protein in the medullary visceral zone were significantly decreased following pretreatment of emulational manual acupuncture and electroacupuncture in rats with visceral traction pain (P〈0.05). Compared with the electroacupuncture group, the leucine-enkephalin content was significantly increased, and pain score was significantly diminished in the emulational manual acupuncture group (P〈0.05).CONCLUSION: Emulational manual acupuncture pretreatment decreases acetylcholine esterase activity, increases leucine-enkephalin release, downregulates expression of c-Fos protein and glial fibrillary acidic protein and ultimately inhibits visceral traction pain by reducing substance P release. The effectiveness in inhibiting visceral traction pain is greater when using emulational manual acupuncture compared with electroacupuncture. This is because emulational manual acupuncture effectively increases leucine-enkephalin release.展开更多

Reliable P-phase onset time picking is necessary for accurate source location needed for planning and rescue operations in the event of failures. In this paper, a new technique based on the discrete stationary wavelet transform (DSWT)and higher order statist!cs, is proposed for processing noisy data from underground mines. The objectives of this method are to (1) Improve manual detection and tPicking of P-phase onset; and (ii) provide an automatic means of detecting and picking P-phase onset me accurately. The DSWT is first used to filter the signal over several scales. The manual P-phase onset detection and picking are then obtained by computing the signal energy across selected scales with frequency bands that capture the signal of interest. The automatic P-phase onset, on the other hand, is achieved by using skewness- and kurtosis-based criterion applied to selected scales in a time-frequency domain. The method was tested using synthetic and field data from an underground limestone mine. Results were compared with results obtained by using the short-term to long-term average (STA/LTA) ratio and that by Reference Ge et al. (2009). The results show that the me!hod provides a more reliable estimate of the P-phase onset arrival than the STA]LTA method when the signal to noise ratio is very low. Also, the results obtained from the field data matched accurately with the results from Reference Ge et al. (2009).展开更多

Forty-four second-year Business English majors at a Chinese university participated in the study. They were divided into equal-sized control and experimental groups. Members of the experimental group were asked to read Chinese-English parallel texts from a user manual, while those of the control group were asked to read the Chinese text only.Subsequently, both groups were required to translate the continued Chinese text into English. The results indicated the following: 1) the experimental group’s translated text was of significantly higher quality than that of the control group;and 2) the experimental group’s translations were well-aligned with the original text in their use of terminology, sentence structure, and stylistic features. The study concludes by suggesting that translation continuation tasks can improve commercial translation instruction and hence should be further applied in practice.展开更多
文摘Background: Osteopathic manual treatment (OMT) has been reported to have positive initial results for subjects with chronic non-specific back pain in a rural safety-net hospital. However, the effects of OMT following initial treatment have not been reported. Objective: To determine the effects of OMT for patients with chronic non-specific back pain in a rural safety-net hospital setting for an initial post-clinical and follow-up visit. Methods: A longitudinal, rolling admission, eleven-year study of cohort study with a primary complaint of chronic, non-specific back pain that had plateaued in improvement for a minimum of six months. One hundred and fifty-one subjects completed the first two study visits necessary for data collection, and fifty-nine subjects completed the follow-up visit after six months. Results: A two-way, mixed model, repeated measures ANOVA with pre- post1 and post2 (follow-up) treatment as the within variable and sex as the between subject variable showed a significant main effect from pre- to follow-up, (F (1, 57) = 21.171, P ηP2= 0.426), but not a significant interaction between time and sex (F (1, 57) = 0.279, P ηP2= 0.002). Conclusions: The results of this study support the hypothesis that OMT has a continued benefit in pain reduction and functional improvement beyond the initial treatment period. The rural, safety-net hospital setting made this study unique relative to the sample population.
文摘Cataract surgery is still the most common surgery performed worldwide.It has evolved tremendously in terms of incision,from 12 mm to 1.8 mm,in terms of capsulotomy from envelope type to automated capsulorhexis,and from rigid intraocular lens to foldable intraocular lenses.Manual small incision cataract surgery(MSICS)remains a valuable technique,particularly in rural and underserved areas,due to its cost-effectiveness and simplicity.Its low logistics and favorable outcomes are particularly useful for managing the cataract backlog in developing countries.This review highlights the history and evolution of MSICS,and the reasons for the advent and popularity of this technique,especially in developing countries.It reviews the various recent modifications of the technique,for example,from a superior incision approach to temporal incision to customized MSICS,2 mm MSICS,and astigmatism-correcting MSICS.It provides an overview of its applicability in complicated scenarios(viz.,small pupil,compromised cornea,pseudoexfoliation,subluxated cataract,etc.).It briefly reviews the clinical trials on MSICS and its comparison with phacoemulsification.Finally,the review emphasizes why every ophthalmic surgeon must know MSICS,its relevance in postgraduate teaching,and the role of MSICS simulators for the same.Overall,the review presents a comprehensive picture of the present status of this technique in the surgical armamentarium of ophthalmology.
文摘[Objectives]This meta-analysis evaluated the efficacy of Traditional Chinese Medicine(TCM)manual therapies(Tuina,Daoyin,acupotomology)for idiopathic scoliosis(IS),with dual focus on radiographic outcomes(Cobb angle,vertebral rotation)and patient-centered metrics(pain,disability,quality of life).[Methods]This study systematically searched PubMed,Cochrane Library,EMBASE,Web of Science,CNKI,Wanfang,and VIP databases(from inception to July 2025)for randomized controlled trials(RCTs)comparing TCM manual therapies against controls(bracing,exercise,sham,or no intervention).Two reviewers independently extracted data and assessed methodological quality using the PEDro scale.Meta-analyses employed random-effects models(Stata 18)to calculate Hedges'g with 95%confidence intervals(CI).Heterogeneity was quantified via I 2 statistics,and subgroup analyses examined intervention types(standalone versus combined)and control groups.[Results]Radiographic outcomes:TCM therapies significantly reduced Cobb angle(Hedges'g=-0.93;95%CI:-1.37,-0.49;p<0.001)and vertebral torsion rotation(VTR;g=-0.71;95%CI:-0.91,-0.51;p<0.001)versus controls;patient-centered outcomes:substantial pain reduction(VAS:g=-1.47;95%CI:-2.64,-0.30;p=0.01)and disability improvement(ODI:g=-1.10;95%CI:-1.57,-0.64;p<0.001)were observed.Quality of life(SRS-22)showed non-significant gains(g=2.01;95%CI:-0.43,4.45;p=0.11).[Conclusions]TCM manual therapies significantly improve spinal alignment and reduce pain/disability in IS patients,particularly when integrated with exercise regimens.While results support their role as complementary interventions,standardization of protocols and long-term efficacy studies are needed for clinical implementation.

文摘The very low cut-off value for sperm morphology of 4% morphologically normal spermatozoa, as proposed in the new edition of the World Health Organization (WHO) manual on semen analysis, is in agreement with recently published values and reflects the trend of a decline in reported mean values for normal sperm morphology. The reduced value for morphologically normal spermatozoa over the years may be due to several factors. The first is the introduction of strict criteria for the evaluation of sperm morphology. Other reasons may include the introduction of additional criteria for sperm morphology abnormalities and the suggested decrease in semen parameters because of increasing negative environmental influences. Although on its own the newly proposed very low normal value may not provide the strong predictive value for a males' fertility potential, as originally reported for sperm morphology evaluated according to strict criteria, a good predictive value can still be obtained if the holistic, strict approach for sperm morphology evaluation is followed together with additional sperm morphology parameters now available, because certain morphology patterns and sperm abnormalities are now known to be of strong prognostic value. In addition, better international standardization of the technical methodology, consensus on the interpretation of sperm morphology evaluation criteria and standardized international external quality control (EQC) schemes, are of utmost importance to maintain the good predictive value of sperm morphology.
文摘S The methane emission flux from rice paddies was simultaneously measured with automatic and manual methods in the suburban of Suzhou. Both methods were based on the static chamber/GC-FID techniques. Detail analysis of the experimental results indicates: a) The data of methane emission measured with the automatic method is reliable. b) About 11 or 19 o′clock of local time is recommended as the optimum sampling time for the manual spot measurement of methane emission from rice paddies. The methane emission fluxes measured by manual sampling at local time other than the optimum time have to be corrected. The correction coefficient may be determined by automatic and continuous measurement. c) In order to get a more accurate result, an empirical correction factor, such as 18%, is recommended to correct the seasonally total amount of measured methane emission by enlarging the automatically measured data or reducing the manually measured ones.

文摘Tibetan Plateau vortices (TPVs) are mesoscale cyclones originating over the Tibetan Plateau (TP) dnring the extended summer season (April-September). Most TPVs stay on the TP, but a small number can move off the TP to the east. TPVs are known to be one of the main precipitation-bearing systems on the TP and moving-off TPVs have been associated with heavy precipitation and flooding downstream of the TP (e.g., in Sichuan province or over the Yangtze River Valley). Identifying and tracking TPVs is difficult because of their comparatively small horizontal extent (400-800 kin) and the limited availability of soundings over the TP, which in turn constitutes a challenge for short-term predictions of TPV-related impacts and for the climatological study of TPVs. In this study, (i) manual tracking (MT) results using radiosonde data from a network over and downstream of the TP are compared with (ii) results obtained by an automated tracking (AT) algorithm applied to ERA-Interim data. Ten MT-TPV cases are selected based on method (i) and matched to and compared with the corresponding AT-TPVs identified with method (ii). Conversely, ten AT-TPVs are selected and compared with the corresponding MT-TPVs. In general, the comparison shows good results in cases where the underlying data are in good agreement, but considerable differences are also seen in some cases and explained in terms of differences in the tracking methods, data availability/coverage and disagreement between sounding and ERA-Interim data. Recommendations are given for future efforts in TPV detection and tracking, including in an operational weather forecasting context.
文摘In the past, victims of electrical and lightning injuries have been assessed in a manner lacking a system- atic formulation, and against ad hoc criteria, particularly in the area of neuropsychological disability. In this manner patients have, for example, only been partially treated, been poorly or incorrectly diagnosed, and have been denied the full benefit of compensation for their injuries. This paper contains a proposal for diagnostic criteria particularly for the neuropsychological aspects of the post injury syndrome. It pays attention to widely published consistent descriptions of the syndrome, and a new cluster analysis of post electrical injury patients. It formulates a proposal which could be incorporated into future editions of the American Psychiatric Association's Diagnostic and Statistical Manual (DSM). The major neuropsycholog- ical consequences include neurocognitive dysfunction, and memory subgroup dysfunction, with ongoing consequences, and sometimes including progressive or delayed psychiatric, cognitive, and/or neurological symptoms. The proposed diagnostic criteria insist on a demonstrated context for the injury, both specifying the shock circumstance, and also physical consequences. It allows for a certain delay in onset of symptoms. It recognizes exclusory conditions. The outcome is a proposal for a DSM classification for the post electrical or lightning injury syndrome. This proposal is considered important for grounding patient treatment, and for further treatment trials. Options for treatment in electrical or lightning injury are summarised, and future trials are foreshadowed.

文摘Acupuncture is an important component part of Traditional Chinese Medicine(TCM).The therapeutic effects may be influenced by a variety of factors.Stimulation quantity is one of the factors for achieving good therapeutic effects in acupuncture practice.With the development of science and technology,besides the influence of manual manipulations,the parameters adopted for electroacupuncture have become the benchmark of stimulation quantity.This study,by referring to the related literatures,is designed to explore the influence of manual manipulations and electrical parameters on therapeutic effects of acupuncture.The results from the present study show that different manualmanipulations and electrical parameters may exert different therapeutic effects of acupuncture,which are closely related to the characteristics of diseases.Different manual manipulations and electrical parameters should be adopted according to syndrome differentiation of TCM.This is very important in acupuncture treatment.
文摘Background The clinical efficacy and safety of adjunctive thrombus aspiration (TA) in patients with ST-segment elevation myocardial infarction (STEMI) during percutaneous coronary intervention (PCI) remain controversial. Methods Twenty five eligible randomized controlled trials were included to compare the use of thrombus aspiration (TA) with PCI and PCI-only for STEMI. The primary endpoint was all-cause mortality and death. The secondary endpoints were major adverse cardiac events (MACE), recurrent infarction (RI), target vessel revascularization (TVR), stent thrombosis (ST), perfusion surrogate markers and stroke. Results TIMI flow grade 3 and MBG 2-3 were significantly increased in the TA plus PCI arm compared with the PCI-only arm [relative risk (RR): 1.05, 95% confidence intervals (CI): 1.02-1.09, P = 0.004] and (RR: 1.68, 95% CI: 1.40-2.00, P 〈 0.001), respectively. There were no significant differences in all-cause mortal- ity, MACEs, TVR and ST rates between the two groups. The RI rate was lower in the TA plus PCI arm than that in the PCI-only arm with short-term follow-up duration (RR: 0.60, 95% CI: 0.38-0.96, P = 0.03), but there was no significant difference in RI incidence over the me- diumor long-term follow-up periods (RR: 1.00, 95% CI: 0.77-1.29, P = 0.98), and (RR: 0.96, 95% CI: 0.81-1.15, P = 0.69), respectively. There were statistically significant differences in the rates of crude stroke and stroke over the medium- or long-term follow-up periods and the crude stroke rate in the TA plus PCI (RR: 1.60, 95% CI: 1.08-2.38, P = 0.02) and (RR: 1.43, 95% CI: 1.03-1.98, P = 0.03), respectively; this was not observed between the two arms during the short-term follow-up period (RR: 1.47, 95% CI: 0.97-2.21, P = 0.07). Conclusions Routine TA-assisted PCI in STEMI patients can improve myocardial reperfusion and get limited benefits related to the clinical endpoints, which may be associated with stroke risk.
文摘Summary: The purpose of this study was to evaluate the ergonomic risk factors associated with manual lifting tasks using surface electromyography (EMG). 13 volunteers lifted loads of 6 and 13 kg at two speeds and at two horizontal distances in 3 different postures and three boxes of different sizes, from floor to knuckle height, performing 72 lifting tasks. For each lift, the surface electromyography signals from the erector spinae muscles, bilaterally at T_~10 and L_3, was recorded. The ergonomic risk factors associated with manual lifting tasks were evaluated by comparing the average amplitude of EMG signals from the erector spinae muscles. The EMG average amplitude for lifting the load of 13 kg was 14.3 % greater than that for lifting the load of 6 kg (t=-10.93, P<0.01). The EMG average amplitude at the site of L_3 was 10.3 % greater than that at the site of T_~10 (t=-7.98, P<0.01). The EMG average amplitude when performing “fast” lift was 5.9 %greater than the “slow” lift (t=-4.63, P<0.01). The posture of lifting affected the EMG average amplitude. It was lowest with semi-squat posture and greatest with squat posture (F=27.76, P<0.01). The result of multiple stepwise regression analysis showed that the loads of lifting, the size of box, horizontal distance, posture of lifting, the site of the spine subjected to force, lifting speed were the factors affecting the EMG average amplitude. The most significant factor was the loads of lifting, followed by the site of the spine subjected to force and the lifting speed in terms of risk. The ergonomic risk factors associated with manual lifting tasks includes the loads, posture, lifting speed, horizontal distance, the site of the spine subjected to force etc. The results of signal amplitude of EMG from the erector spinae muscles showed that semi-squat posture is the best posture for lifting tasks.

文摘Manual acupuncture is widely used for pain relief and stress control.Previous studies on acupuncture have shown its modulatory effects on the functional connectivity associated with one or a few preselected brain regions.To investigate how manual acupuncture modulates the organization of functional networks at a whole-brain level,we acupuncture at ST36 of a right leg to obtain electroencephalograph(EEG) signals.By coherence estimation,we determine the synchronizations between all pairwise combinations of EEG channels in three acupuncture states.The resulting synchronization matrices are converted into functional networks by applying a threshold,and the clustering coefficients and path lengths are computed as a function of threshold.The results show that acupuncture can increase functional connections and synchronizations between different brain areas.For a wide range of thresholds,the clustering coefficient during acupuncture and postacupuncture period is higher than that during the pre-acupuncture control period,whereas the characteristic path length is shorter.We provide further support for the presence of "small-world" network characteristics in functional networks by using acupuncture.These preliminary results highlight the beneficial modulations of functional connectivity by manual acupuncture,which could contribute to the understanding of the effects of acupuncture on the entire brain,as well as the neurophysiological mechanisms underlying acupuncture.Moreover,the proposed method may be a useful approach to the further investigation of the complexity of patterns of interrelations between EEG channels.

文摘Objective:This study is conducted to determine effects of manual acupuncture(MA)in patients with a diagnosis of major depressive disorder(MDD)and comorbid insomnia.Methods:A total of 67 participants who met the inclusion criteria were randomly enrolled in a two-arm randomized,placebo controlled,patients-blind trial and allocated to a real-MA group(patients=34)and a sham-MA group(patients=33).Patients in the real-MA group were treated on‘Five-shen acupoints’,including Sishencong(四神聪EX-HN 1),Shenting(神庭GV 24),Shendao(神道GV 11),bilateral Benshen(本神GB 13),and bilateral Shenmen(神门HT 7).Though being punctured on the same acupoints,patients in the sham-MA group were treated by a placebo acupuncture approach(Streitberger Placeboneedle).Each group received corresponding interventions every other day,three times a week for total eight weeks.Both polysomnography(PSG)and testing of serum biological markers such as neuropeptide Y(NPY)and substance P(SP)were performed at pre-and post-treatment.Additionally,the global scores of Pittsburgh sleep quality index(PSQI)and the global scores of 17-items Hamilton Depression Rating Scale(HAMD17)were used for assessing the subjective sleep and emotion experience of patients,respectively.Meanwhile,adverse effects were monitored and recorded.Results:After eight-week treatment,the global scores of PSQI and global scores of HAMD17 declined significantly(both P<0.05)in the real-MA group but not in the sham-MA group(both P>0.05).According to the parameters of PSG,striking decline were observed in sleep latency(SL)and wake after sleep onset(WASO)and striking climb were observed in total sleep time(TST)and sleep efficiency(SE)in the real-MA group after treatment(P<0.05,respectively)but not in the sham-MA group(P>0.05,respectively).Additionally,there were no significant differences in awakening times(ATs)and rapid eyes movement sleep latency(REM-SL)in both two groups after treatment(both P>0.05).Meanwhile,the expression of NPY increased significantly and the expression of SP decreased significantly in the real-MA group after interventions(both P<0.05)while those indicators only slightly fluctuated in the sham-MA group(P>0.05).No serious adverse event was reported in either real-or sham-MA group.Conclusion:(1)MA may be a potential alternative therapy for improving MDD and comorbid insomnia(particularly in extending total sleep time and shortening wake-up duration and sleep latency)via upregulating the expression of NPY and downregulating the expression of SP;more importantly,this efficacy of acupuncture can not be replaced by sham-acupuncture acting on the same acupoints with the same treatment frequency.(2)There is insufficient evidence to prove that MA can effectively reduce the number of arousals.
文摘OBJECTIVE: To ascertain if it is effective to use extradural injections and manual repositioning of the spine to treat megalgia caused by cervical spondy- Iotic radiculopathy (CSR). METHODS: Patients with megalgia caused by CSR were divided into a treatment group (n=46) treated by extradural injection and manual repositioning of the spine and a control group (n=46) treated by a conventional method. RESULTS: The prevalence of cure was 58.69% and the total prevalence of effective cure in the treatment group was 97.83% and was 23.91% and 78.26%, respectively, in the control group: this difference between the two groups was significant (P〈 0.05). CONCLUSION: Treatment of megalgia caused by CSR by extradural injections and manual repositioning of the spine has a good curative effect with rapid analgesia and short therapeutic course.
文摘AIM: To evaluate the impact of thrombus aspiration(TA) on procedural outcomes in a real-world ST-segment elevation myocardial infarction(STEMI) registry.METHODS: From May 2006 to August 2008, 542 consecutive STEMI patients referred for primary or rescue percutaneous coronary intervention were enrolled and the angiographic results and stent implantation characteristics were compared according to the performance of manual TA.RESULTS: A total of 456 patients were analyzable and categorized in TA group(156 patients; 34.2%) and non-TA(NTA) group(300 patients; 65.8%). Patientstreated with TA had less prevalence of multivessel disease(39.7% vs 54.7%, P = 0.003) and higher prevalence of initial thrombolysis in myocardial infarction flow 【 3(P 【 0.001) than NTA group. There was a higher rate of direct stenting(58.7% vs 45.5%, P = 0.009), with shorter(24.1 ± 11.8 mm vs 26.9 ± 15.7 mm, P = 0.038) and larger stents(3.17 ± 0.43 mm vs 2.93 ± 0.44 mm, P 【 0.001) in the TA group as compared to NTA group. The number of implanted stents(1.3 ± 0.67 vs 1.5 ± 0.84, P = 0.009) was also lower in TA group. CONCLUSION: In an “all-comers” STEMI population, the use of TA resulted in more efficient procedure leading to the implantation of less number of stents per lesion of shorter lengths and larger sizes.

文摘BACKGROUND: Acupuncture and moxibustion against visceral noxious stimulation present different mechanisms in the peripheral and central nervous systems, involving release of neurotransmitter substance P, acetylcholine esterase, leucine-enkephalin, and c-Fos protein expression. However, there are few reports addressing changes in neurotransmitter expression following manual acupuncture and electroacupuncture against visceral traction pain.OBJECTIVE: To explore changes in neurotransmitter expression in the ileum and protein expression in the medullary visceral zone of visceral traction pain rats undergoing pretreatment of emulational manual acupuncture, and to investigate the differences between emulational manual acupuncture and electroacupuncture.DESIGN, TIME AND SETTING: The randomized, controlled study was performed at the Biomedical Engineering Laboratory, Shanghai University of Traditional Chinese Medicine, Shanghai, China from August 2008 to July 2009.MATERIALS: G6805 electroacupuncture apparatus (Shanghai Medical Electronic Machine Factory, China) and ZSF-I acupuncture manipulation simulation therapeutic system (Chinese Medical Engineering Room, Shanghai University of Traditional Chinese Medicine, Shanghai China) were used in the present study.METHODS: A total of 40 male Sprague Dawley rats were equally and randomly assigned to sham surgery, model, emulational manual acupuncture and electroacupuncture groups. In the emulational manual acupuncture and electroacupuncture groups, emulational manual acupuncture and electroacupuncture were applied at bilateral Zusanli (ST 36) acupoints for 30 minutes, and models of visceral traction pain were established immediately.MAIN OUTCOME MEASURES: Substance P expression, c-Fos and glial fibrillary acidic protein expression were measured using immunohistochemistry. Acetylcholine esterase activity was examined utilizing a colorimetric method. Leucine-enkephalin content was detected using a radioimmune assay. Degree of pain in rats was assessed by pain score.RESULTS: Pain score, substance P expression in the ileum, acetylcholine esterase activity, expression of c-Fos protein and glial fibrillary acidic protein in the medullary visceral zone were significantly decreased following pretreatment of emulational manual acupuncture and electroacupuncture in rats with visceral traction pain (P〈0.05). Compared with the electroacupuncture group, the leucine-enkephalin content was significantly increased, and pain score was significantly diminished in the emulational manual acupuncture group (P〈0.05).CONCLUSION: Emulational manual acupuncture pretreatment decreases acetylcholine esterase activity, increases leucine-enkephalin release, downregulates expression of c-Fos protein and glial fibrillary acidic protein and ultimately inhibits visceral traction pain by reducing substance P release. The effectiveness in inhibiting visceral traction pain is greater when using emulational manual acupuncture compared with electroacupuncture. This is because emulational manual acupuncture effectively increases leucine-enkephalin release.
文摘Accurate detection and picking of the P-phase onset time in noisy microseismic data from underground mines remains a big challenge. Reliable P-phase onset time picking is necessary for accurate source location needed for planning and rescue operations in the event of failures. In this paper, a new technique based on the discrete stationary wavelet transform (DSWT)and higher order statist!cs, is proposed for processing noisy data from underground mines. The objectives of this method are to (1) Improve manual detection and tPicking of P-phase onset; and (ii) provide an automatic means of detecting and picking P-phase onset me accurately. The DSWT is first used to filter the signal over several scales. The manual P-phase onset detection and picking are then obtained by computing the signal energy across selected scales with frequency bands that capture the signal of interest. The automatic P-phase onset, on the other hand, is achieved by using skewness- and kurtosis-based criterion applied to selected scales in a time-frequency domain. The method was tested using synthetic and field data from an underground limestone mine. Results were compared with results obtained by using the short-term to long-term average (STA/LTA) ratio and that by Reference Ge et al. (2009). The results show that the me!hod provides a more reliable estimate of the P-phase onset arrival than the STA]LTA method when the signal to noise ratio is very low. Also, the results obtained from the field data matched accurately with the results from Reference Ge et al. (2009).
文摘Based on the xu-argument, this study investigated the use of translation continuation tasks in commercial translation instruction. Forty-four second-year Business English majors at a Chinese university participated in the study. They were divided into equal-sized control and experimental groups. Members of the experimental group were asked to read Chinese-English parallel texts from a user manual, while those of the control group were asked to read the Chinese text only.Subsequently, both groups were required to translate the continued Chinese text into English. The results indicated the following: 1) the experimental group’s translated text was of significantly higher quality than that of the control group;and 2) the experimental group’s translations were well-aligned with the original text in their use of terminology, sentence structure, and stylistic features. The study concludes by suggesting that translation continuation tasks can improve commercial translation instruction and hence should be further applied in practice.
