In large-scale hospitals practicing traditional Chinese medicine, there is accumulating experience related to the promotion of fast recovery in the perioperative period.AIM To evaluate the efficacy and safety of Yikou-Sizi powder hot compress on Shenque acupuncture point combined with rapid rehabilitation technique.METHODS This prospective, multicenter, randomized, controlled study included two groups: Treatment group and control group. The patients in the treatment group and control group received Yikou-Sizi powder hot compress on Shenque acupuncture point combined with rapid rehabilitation technique and routine treatment, respectively. Clinical observation regarding postoperative recovery of gastrointestinal function was performed, including the times to first passage of flatus, first defecation, and first normal bowel sounds. The comparison between groups was conducted through descriptive analysis, χ~2, t, F, and rank-sum tests.RESULTS There was a statistically significant difference in the time to postoperative first defecation between the treatment and control group(87.16 ± 32.09 vs 109.79 ±40.25 h, respectively;P < 0.05). Similarly, the time to initial recovery of bowel sounds in the treatment group was significantly shorter than that in the control group(61.17 ± 26.75 vs 79.19 ± 33.35 h, respectively;P < 0.05). However, there was no statistically significant difference in the time to initial exhaust between the treatment and control groups(51.54 ± 23.66 vs 62.24 ± 25.95 h, respectively;P >0.05). The hospitalization expenses for the two groups of patients were 62283.45 ±12413.90 and 62059.42 ± 11350.51 yuan, respectively. Although the cost of hospitalization was decreased in the control group, the difference was not statistically significant(P > 0.05). This clinical trial was safe without reports of any adverse reaction or event.CONCLUSION The rapid rehabilitation technique with integrated traditional Chinese and Western medicine promotes the recovery of postoperative gastrointestinal function and is significantly better than standard approach for patients after colorectal surgery.展开更多

The results showed that the soil erodibility decreased significantly after the vegetation restoration. The climate environment of the small watershed had a great improvement after the vegetation restoration, of which the temperature decreased, the humidity increased, the harsh environment of dry and hot in this region changed. The studies of the ecosystem biodiversity were mainly on the analysis of the relations between biodiversity and ecological function of the artificial ecological forest pattern and the natural enclosed treatment mode on the severely of degraded land. It could conclude that the natural enclosed treatment mode is helpful to the biodiversity of the ecosystem and the improvement and stability of the ecosystem, and Leucaena artificial forest restoration pattern reduced the species diversity but optimized the ecological function. Therefore, as to the severely and extremely severely degraded ecosystem in the arid-hot valleys, Leucaena pattern of gully control and natural enclosed treatment mode are the relatively optimal choices.展开更多

It is essential to investigate the level of impurities in order to develop reliable monitoring and control strategies. This paper described one approach based on generation function technique with the following two steps. First, a new mechanism for propylene polymerization was proposed by considering the effects of the reactive impurities in the material on the propylene polymerization. Second, a series of equations of population balance for the propylene polymerization in loop reactors were established based on the proposed mechanism. Accordingly, the equations were transformed into the mathematic matrix through the generation function technique to investigate the effects of the reactive impurities on the propylene polymerization. Significant effects of the reactive impurities were analyzed through computational simulation. The results show that the concentration of active centre on catalysts and the polymerization conversion both decrease with the increase of the initial concentration of any reactive impurity; hydrogen concentration decreases with the increase of the initial concentration of ethylene or butylenes, whereas, it increases with the increase of the initial concentration of propadiene; the simulated weight average molecular weight and the molecular weight distribution index of polymer resins both increase with the increase of the initial concentration of ethylene or butylenes. They decrease with the increase of the initial concentration of propadiene.展开更多

The general procedure is shown, and the parameter determination is explained through the applications to this particular case I1/6(x)and I1/7(x). In this way, it shows how to apply the technique to any particular orderν, in order to obtain an approximation valid for any positive value of the variable x. In the present method power series and asymptotic expansion are simultaneously used. The technique is an extension of the multipoint quasirational approximation method, MPQA. The main idea is to look for a bridge function between the power and asymptotic expansion of the I1/6(x), and similar procedure for I1/7(x). To perform this, rational functions are combined with hyperbolic ones and fractional powers. The number of parameters to be determined for each case is four. The maximum relative errors are 0.0049 for ν=1/6, and 0.0047 for ν=7. However, these relative errors decrease outside of the small region of the variables, wherein the maximum relative errors are reached. There is a clear advantage of this procedure compared with any other ones.展开更多

After guidance, the puerpera in the control group were given pelvic floor muscle training by themselves at home. On this basis, the puerpera in the treatment group were treated by the pelvic floor rehabilitation apparatus. The puerpera in the two groups were treated for 4 weeks. The pelvic floor function before treatment, 6 months and 1 year after delivery was detected. The color Doppler ultrasound apparatus was used to detect BSD, PUVA, UVJ-M, and BND 3 months after delivery.Results:BND, PUVA-R, PUVA-S, and UVJ-M 3 months after delivery in the treatment groups were significantly lower than those in the control group, while BSD-S was significantly higher than that in the control group. The improvement of type I and Ⅱ muscle fiber fatigue (%), POP-Q degree, AP indication point (cm), and vaginal dynamic pressure (cmH2O) was significantly superior to that in the control group. The comparison of pelvic floor muscle strength classification before treatment between the two groups was not statistically significant. After treatment, the pelvic floor muscle in the two groups was significantly strengthened, and the proportion of V grade patients was significantly increased when compared with before treatment.Conclusions: The postpartum early pelvic floor rehabilitation technique can effectively enhance the pelvic floor function, and prevent the postpartum pelvic floor dysfunction, with an accurate efficacy;therefore, it deserves to be widely recommended in the clinic.展开更多

This triggers significant efforts to reveal the fundamental mechanism determining batteryperformance with the use of advanced analytical techniques. However, the inherently complex character-istics of battery systems make the mechanism analysis sophisticated and difficult. Synchrotron radiationis an advanced collimated light source with high intensity and tunable energies. It has particular ad-vantages in electronic structure and geometric structure （both the short-range and long-range structure）analysis of materials on different length and time scales. In the past decades, synchrotron X-ray tech-niques have been widely used to understand the fundamental mechanism and guide the technologicaloptimization of batteries. In particular, in situ and operando techniques with high spatial and temporalresolution, enable the nondestructive, real time dynamic investigation of the electrochemical reaction,and lead to significant deep insights into the battery operation mechanism. This review gives a brief introduction of the application of synchrotron X-ray techniques to the inves-tigation of battery systems. The five widely implicated techniques, including X-ray diffraction （XRD）, PairDistribution Function （PDF）, Hard and Soft X-ray absorption spectroscopy （XAS） and X-ray photoelectronspectroscopy （XPS） will be reviewed, with the emphasis on their in situ studies of battery systems during cycling.展开更多

Methods: The potential of CNS was induced by six-step Daoyin technique of Chinese medicine, and the potential signal was received in real time by bio-electrical signal receiving equipment and displayed in curve form. Combined with the Operant conditioning biofeedback technique, targeted guidance was given to patients to continuously enhance the action muscle signal intensity and weaken the antagonistic muscle signal intensity, so that the motor program was gradually re-established. Sixty-four patients with hemiplegic elbow dysfunction of old cerebral infarction who had been trained but could not be improved further and had a history of more than 1 year were treated for one course, 90 times and 45 minutes each time. Lovett, Elbow Rom, Fugl-Meyer, program signal intensity and proportion were evaluated before and after treatment. The data were analyzed statistically. Before and after treatment, Lovett MMT, ROM of elbow joint, Fugl Meyer, motor program signal intensity and proportion were assessed, and the data were statistically analyzed. Results: After treatment and before treatment, there was a significant difference between the functional evaluation data (P < 0.01). The function of elbow joint was improved;this is the result of reconstructing the motor program on the basis of developing the potential of CNS by means of the “transcendental goal power” mechanism of the method. There was no recurrence after 6 months of follow-up. Conclusion: The Chinese Medicine Daoyin feedback rehabilitation technique is an effective method to improve elbow joint function of hemiplegia patients with cerebral infarction.展开更多

First, in order to enhance the image contrast, we proposed new adaptive histogram transformation combining histogram equalization and histogram specification. Here, by examining the characteristic of histogram distribution shape, we determine the appropriate target distribution. Next, applying the histogram equalization with an image histogram, we have obtained the uniform distribution of pixel values, and then we have again carried out the histogram transformation using an inverse of target distribution function. Finally we have conducted various experiments that can enhance the quality of image by applying our method with various standard images. The experimental results show that the proposed method can achieve moderately good image enhancement results.展开更多

The former is the Duck site in North Carolina, on the east coast of the USA, which is exposed to Atlantic Ocean swells and storm waves, and the latter is the Milford-on-Sea site at Christchurch Bay, on the south coast of England, which is partially sheltered from Atlantic swells but has a directionally bimodal wave exposure. The data sets comprise detailed bathymetric surveys of beach profiles covering a period of more than 25 years for the Duck site and over 18 years for the Milford-on-Sea site. The structure of the data sets and the data-driven methods are described. Canonical correlation analysis （CCA） was used to find linkages between the wave characteristics and beach profiles. The sensitivity of the linkages was investigated by deploying a wave height threshold to filter out the smaller waves incrementally. The results of the analysis indicate that, for the gently sloping sandy beach, waves of all heights are important to the morphological response. For the mixed sand and gravel beach, filtering the smaller waves improves the statistical fit and it suggests that low-height waves do not play a primary role in the medium-term morohological resoonse, which is primarily driven by the intermittent larger storm waves.展开更多

文摘Objective:To observe the differences of clinical effect and influence on joint function and inflammatory markers in joint fluid between stuck-needle technique and regular acupuncture in patients with knee osteoarthritis.Methods:Seventy-two patients with knee osteoarthritis were randomly divided into a stuck-needle technique group and a regular acupuncture group,with 36 cases in each one.The selection of acupoints,retaining time of needles,and treatment course were all the same in both groups.The visual analog scale(VAS)score,Lequesne index score,and the content of related inflammatory indexes in joint fluid before and after treatment were observed,and the therapeutic effect were evaluated.Results:After treatment,the VAS scores,Lequesne index scores,interleukin-1 beta(IL-1β),and the tumor necrosis factor a(TNF-α)of the two groups were all lower than those before treatment(all P<0.05).After treatment,the VAS scores,Lequesne index scores,IL-1β,and TNF-αof the stuck-needle technique group were all lower than those of the regular acupuncture group(all P<0.05).The total effective rate of the stuck-needle technique group was 96.97%(32/33),higher than 93.75%(30/32)of the regular acupuncture group(P<0.05).Conclusion:Stuck-needle technique can effectively relieve the pain and improve the joint functions,being more effective than regular acupuncture for the treatment of knee osteoarthritis.
文摘Respiratory diseases,especially asthma,are common in children.While spirometry contributes to asthma diagnosis and management in older children,it has a limited role in younger children whom are often unable to perform forced expiratory manoeuvre.The development of novel diagnostic methods which require minimal effort,such as forced oscillation technique(FOT)is,therefore,a welcome and promising addition.FOT involves applying external,small amplitude oscillations to the respiratory system during tidal breathing.Therefore,it requires minimal effort and cooperation.The FOT has the potential to facilitate asthma diagnosis and management in preschool children by faciliting the objective measurement of baseline lung function and airway reactivity in children unable to successfully perform spirometry.Traditionally the use of FOT was limited to specialised centres.However,the availability of commercial equipment resulted in its use both in research and in clinical practice.In this article,we review the available literature on the use of FOT in childhood asthma.The technical aspects of FOT are described followed by a discussion of its practical aspects in the clinical field including the measurement of baseline lung function and associated reference ranges,bronchodilator responsiveness and bronchial hyperresponsiveness.We also highlight the difficulties and limitations that might be encountered and future research directions.

文摘Recently,we read a retrospective study by Chen et al,which demonstrated that electroacupuncture is highly effective in relieving pain due to rotator cuff injuries and accelerating the recovery of shoulder function,promoting repair of rotator cuff injuries.This study provides a new way to the conservative treatment of early rotator cuff injuries.In the present letter,we review the current treatment of rotator cuff injury with electroacupuncture combined with rehabilitation techniques and propose our views.
文摘Rectal cancer ranks as the third most prevalent malignancy globally,with an estimated 1.9 million incident cases reported in 2020.The management of low rectal cancer presents significant therapeutic challenges due to its anatomical complexity,and substantially impacts patients'quality of life.While abdominoperineal resection(Miles procedure)ensures oncological radicality,the morbidity associated with permanent colostomy has driven innovations in sphincter-preserving surgical techniques.This review synthesizes current evidence on sphincter-preserving surgical approaches for low rectal cancer.The implementation of total mesorectal excision(TME)principles and enhanced understanding of circumferential resection margin have facilitated the evolution of diverse sphincter-preserving surgical modalities.These include local excision,low anterior resection(Dixon procedure),intersphincteric resection,pull-through procedures,transanal TME,and conventional sphincter-preserving operation.Minimally invasive approaches,particularly laparoscopic and robotic platforms,alongside natural orifice transluminal endoscopic surgery,have demonstrated improved surgical precision and enhanced postoperative recovery outcomes.Novel functional perineal reconstruction techniques offer promising alternatives for patients requiring posterior pelvic exenteration.Nevertheless,the high incidence of low anterior resection syndrome(LARS)and its chronic sequelae remain clinically notable.Evidence indicates that long-course neoadjuvant radiotherapy and TME constitute significant risk factors for LARS development.Contemporary sphincter-preserving surgery for low rectal cancer is advancing toward minimally invasive,personalized,and precision-based approaches.The increasing incidence of early-onset rectal cancer necessitates individualized treatment strategies that balance oncological efficacy with functional preservation.Future directions should focus on standardizing surgical indications,optimizing postoperative rehabilitation protocols,and enhancing treatment outcomes through multidisciplinary integration and technological innovation.

文摘A numerical technique is presented for solving integration operator of Green’s function. The approach is based on Hermite trigonometric scaling function on [0,2π], which is constructed for Hermite interpolation. The operational matrices of derivative for trigonometric scaling function are presented and utilized to reduce the solution of the problem. One test problem is presented and errors plots show the efficiency of the proposed technique for the studied problem.
文摘A general technique to obtain simple analytic approximations for the first kind of modified Bessel functions. The general procedure is shown, and the parameter determination is explained through the applications to this particular case I1/6(x)and I1/7(x). In this way, it shows how to apply the technique to any particular orderν, in order to obtain an approximation valid for any positive value of the variable x. In the present method power series and asymptotic expansion are simultaneously used. The technique is an extension of the multipoint quasirational approximation method, MPQA. The main idea is to look for a bridge function between the power and asymptotic expansion of the I1/6(x), and similar procedure for I1/7(x). To perform this, rational functions are combined with hyperbolic ones and fractional powers. The number of parameters to be determined for each case is four. The maximum relative errors are 0.0049 for ν=1/6, and 0.0047 for ν=7. However, these relative errors decrease outside of the small region of the variables, wherein the maximum relative errors are reached. There is a clear advantage of this procedure compared with any other ones.

文摘Microglia,the resident immune cells of the central nervous system,exhibit a wide array of functional states,even in their so-called“homeostatic”condition,when they are not actively responding to overt pathological stimuli.These functional states can be visualized using a combination of multi-omics techniques(e.g.,gene and protein expression,posttranslational modifications,mRNA profiling,and metabolomics),and,in the case of homeostatic microglia,are largely defined by the global(e.g.,genetic variations,organism’s age,sex,circadian rhythms,and gut microbiota)as well as local(specific area of the brain,immediate microglial surrounding,neuron-glia interactions and synaptic density/activity)signals(Paolicelli et al.,2022).While phenomics(i.e.,ultrastructural microglial morphology and motility)is also one of the key microglial state-defining parameters,it is known that cells with similar morphology can belong to different functional states.
文摘Objective:To explore the effect of pelvic floor rehabilitation technique in preventing the postpartum pelvic floor dysfunction and on the sexual life quality.Methods:A total of 286 puerpera with pelvic floor dysfunction who were admitted in our hospital from May, 2014 to May, 201542 d after delivery were included in the study, and randomized into the treatment group and the control group with 143 cases in each group. After guidance, the puerpera in the control group were given pelvic floor muscle training by themselves at home. On this basis, the puerpera in the treatment group were treated by the pelvic floor rehabilitation apparatus. The puerpera in the two groups were treated for 4 weeks. The pelvic floor function before treatment, 6 months and 1 year after delivery was detected. The color Doppler ultrasound apparatus was used to detect BSD, PUVA, UVJ-M, and BND 3 months after delivery.Results:BND, PUVA-R, PUVA-S, and UVJ-M 3 months after delivery in the treatment groups were significantly lower than those in the control group, while BSD-S was significantly higher than that in the control group. The improvement of type I and Ⅱ muscle fiber fatigue (%), POP-Q degree, AP indication point (cm), and vaginal dynamic pressure (cmH2O) was significantly superior to that in the control group. The comparison of pelvic floor muscle strength classification before treatment between the two groups was not statistically significant. After treatment, the pelvic floor muscle in the two groups was significantly strengthened, and the proportion of V grade patients was significantly increased when compared with before treatment.Conclusions: The postpartum early pelvic floor rehabilitation technique can effectively enhance the pelvic floor function, and prevent the postpartum pelvic floor dysfunction, with an accurate efficacy;therefore, it deserves to be widely recommended in the clinic.

文摘The increased use of rechargeable batteries in portable electronic devices and the continuous develop-ment of novel applications （e.g. transportation and large scale energy storage）, have raised a strong de-mand for high performance batteries with increased energy density, cycle and calendar life, safety andlower costs. This triggers significant efforts to reveal the fundamental mechanism determining batteryperformance with the use of advanced analytical techniques. However, the inherently complex character-istics of battery systems make the mechanism analysis sophisticated and difficult. Synchrotron radiationis an advanced collimated light source with high intensity and tunable energies. It has particular ad-vantages in electronic structure and geometric structure （both the short-range and long-range structure）analysis of materials on different length and time scales. In the past decades, synchrotron X-ray tech-niques have been widely used to understand the fundamental mechanism and guide the technologicaloptimization of batteries. In particular, in situ and operando techniques with high spatial and temporalresolution, enable the nondestructive, real time dynamic investigation of the electrochemical reaction,and lead to significant deep insights into the battery operation mechanism. This review gives a brief introduction of the application of synchrotron X-ray techniques to the inves-tigation of battery systems. The five widely implicated techniques, including X-ray diffraction （XRD）, PairDistribution Function （PDF）, Hard and Soft X-ray absorption spectroscopy （XAS） and X-ray photoelectronspectroscopy （XPS） will be reviewed, with the emphasis on their in situ studies of battery systems during cycling.
文摘Objective: To study an anti resistance active exercise training method which is consistent with the principle of “transcendental goal power” to promote the plasticity change of central nervous system (CNS) in order to recover the motor function after CNS injury, observe its clinical effect and explore its mechanism. Methods: The potential of CNS was induced by six-step Daoyin technique of Chinese medicine, and the potential signal was received in real time by bio-electrical signal receiving equipment and displayed in curve form. Combined with the Operant conditioning biofeedback technique, targeted guidance was given to patients to continuously enhance the action muscle signal intensity and weaken the antagonistic muscle signal intensity, so that the motor program was gradually re-established. Sixty-four patients with hemiplegic elbow dysfunction of old cerebral infarction who had been trained but could not be improved further and had a history of more than 1 year were treated for one course, 90 times and 45 minutes each time. Lovett, Elbow Rom, Fugl-Meyer, program signal intensity and proportion were evaluated before and after treatment. The data were analyzed statistically. Before and after treatment, Lovett MMT, ROM of elbow joint, Fugl Meyer, motor program signal intensity and proportion were assessed, and the data were statistically analyzed. Results: After treatment and before treatment, there was a significant difference between the functional evaluation data (P < 0.01). The function of elbow joint was improved;this is the result of reconstructing the motor program on the basis of developing the potential of CNS by means of the “transcendental goal power” mechanism of the method. There was no recurrence after 6 months of follow-up. Conclusion: The Chinese Medicine Daoyin feedback rehabilitation technique is an effective method to improve elbow joint function of hemiplegia patients with cerebral infarction.
文摘This paper presents a preprocessing technique that can provide the improved quality of image robust to illumination changes. First, in order to enhance the image contrast, we proposed new adaptive histogram transformation combining histogram equalization and histogram specification. Here, by examining the characteristic of histogram distribution shape, we determine the appropriate target distribution. Next, applying the histogram equalization with an image histogram, we have obtained the uniform distribution of pixel values, and then we have again carried out the histogram transformation using an inverse of target distribution function. Finally we have conducted various experiments that can enhance the quality of image by applying our method with various standard images. The experimental results show that the proposed method can achieve moderately good image enhancement results.

文摘In this study the medium-term response of beach profiles was investigated at two sites： a gently sloping sandy beach and a steeper mixed sand and gravel beach. The former is the Duck site in North Carolina, on the east coast of the USA, which is exposed to Atlantic Ocean swells and storm waves, and the latter is the Milford-on-Sea site at Christchurch Bay, on the south coast of England, which is partially sheltered from Atlantic swells but has a directionally bimodal wave exposure. The data sets comprise detailed bathymetric surveys of beach profiles covering a period of more than 25 years for the Duck site and over 18 years for the Milford-on-Sea site. The structure of the data sets and the data-driven methods are described. Canonical correlation analysis （CCA） was used to find linkages between the wave characteristics and beach profiles. The sensitivity of the linkages was investigated by deploying a wave height threshold to filter out the smaller waves incrementally. The results of the analysis indicate that, for the gently sloping sandy beach, waves of all heights are important to the morphological response. For the mixed sand and gravel beach, filtering the smaller waves improves the statistical fit and it suggests that low-height waves do not play a primary role in the medium-term morohological resoonse, which is primarily driven by the intermittent larger storm waves.
