Methods Fifty-one patients with renal colic were randomly divided into an electroacupuncture group （26 cases） and a medicine group （25 cases）. In the electroacupuncture group, electroacupuncture was applied to the Xi-cleft points of kidney and bladder meridians, named Shuǐquán （水泉 KI 5） and Jīnmén （金门 BL 63） as well as the relevant Front-mu points, Jīngmén （京门 GB 25） and Zhōngjí （中极 CV 3）. In the medicine group, intramuscular injection with Fortanodyn （100 mg） was administered. Once treatment was applied for immediate analgesia in each group. Before and after treatment, the Simplified McGill Pain Questionnaire （SF-MPQ） and the Visual Analogy Scale （VAS） were adopted for pain assessment respectively. The clinical efficacy and the recurrence of the disease were observed in the two groups. Results The clinically cured and remarkably effective rate was 69.2% （18/26） in the electroacupuncture group, which was superior to 44.0% （11/25） in the medicine group （P0.05）. Separately, in 10 min, 30 min, 60 min and 120 min after treatment, in either group, SF-MPQ and VAS scores were obviously reduced as compared with those before treatment （all P0.05）. The scores in 10 min and 30 min after treatment in the electroacupuncture group were reduced more remarkably as compared with those in the medicine group （both P0.05）. The complete remission time in the electroacupuncture group was shorter apparently than that in the medicine group [（131.19±152.12） min vs （184.29±84.04） min, P0.05]. The recurrence rate of renal colic in 24 h was 8.0% （2/25） in the electroacupuncture group, which was lower slightly than 31.6% （6/19） in the medicine group （P0.05）. Conclusion Renal colic can be effectively relieved in the treatment with either electroacupuncture at the Xi-cleft points and the Front-mu points of kidney and bladder meridians or intramuscular injection with Fortanodyn. But, the electroacupuncture therapy achieves much better efficacy.展开更多

A rat model of hyperuricemia was developed by intragastric administration of adenine and ethambutol. This experiment last for 90 d in total. Treatment groups underwent 3 courses of acupuncture. Each course involved a total of 10 interventions(one intervention every second day) with each intervention lasting15 min. There was a break for 10 d between courses. SUA and ALP were analyzed using an automatic biochemical analyzer and XOD was analyzed using immunofluorescence.RESULTS: Compared with the blank group, SUA and XOD levels in the model group were significantly higher and the renal index significantly improved. Compared with the model group, SUA and XOD levels in the three treatment groups decreased and the renal index significantly improved.When the three treatment groups were compared,the Mu-acupoint group showed the greatest decreases in SUA and XOD levels, followed by the Yuan-acupoint group. There was no significant difference in kidney index among the three treatment groups. There was no significant difference in ALP levels among the groups.CONCLUSION: The three treatments showed significantly reduced SUA and XOD levels compared with the control groups, possibly suggesting reduced renal damage.展开更多

Hyaluronan interacts with various receptors in the human body, including CD44, LYVE-1, RHAMM, and TLR2, and is well-known for its analgesic effects when used in intra-articular or ultrasound-guided nerve trunk injections. Studies have shown that hyaluronidase cleaves high molecular weight HA to generate HA35, a low molecular weight fragment with enhanced tissue permeability, capable of binding to HA receptors on cell surfaces to produce broad-spectrum analgesic effects. Methods: Ten patients diagnosed with MPS were treated and assessed in this study. HA35 was administered through injection at a dosage of 100 mg daily for 15 days. Patients evaluated their MPS, overall pain levels, and treatment satisfaction using the Numerical Pain Rating Scale (NPRS), the Global Pain Scale (GPS), and the Treatment Satisfaction Questionnaire for Medication (TSQM 1.4). Follow-up evaluations were performed three months post-treatment to assess the duration of therapeutic effects. Results: Significant improvements were observed in NPRS, GPS, and TSQM scores both during and after the treatment period (P Conclusions: HA35 provides effective and sustained relief from pain associated with MPS, demonstrating a prolonged therapeutic benefit.展开更多

We consider an open system consisting of two coupled qubits and each qubit is contacted with a thermal bath at a different temperature. In the case of omitting quantum jumps, we find that the system exhibits a second-order HEP, which separates the parameter space into an overdamped regime and an underdamped regime. In this situation, the LGI and NSIT conditions can be violated in both regimes and not violated at the HEP. In the case of without omitting quantum jumps, we find that the system exhibits a third-order LEP, which also separates the parameter space into an overdamped regime and an underdamped regime. In this situation, the LGI can only be violated in the underdamped regime with large coupling strength between the qubits.Conversely, the NSIT conditions can be violated in both regimes, as well as at the LEP, except in the overdamped regime with small coupling strength between the qubits. Comparing the violations of the LGI and NSIT conditions with HEP and LEP, we find that the quantum jumps would reduce the generation of coherence, enhance the decoherence, and lead to narrower parameter regimes that the LGI and NSIT conditions can be violated. Furthermore, in both cases,the NSIT conditions can be violated in a wider parameter regime than the LGI.展开更多

Methods Seventy healthy SD rats were randomly divided into seven groups, including control group, model group, ＂Zúsānlǐ＂（足三里 ST 36） group, ＂Shàngjùxū＂（上巨虚 ST 37） group, ＂Xiàjùxū＂（下巨虚 ST 39） group, ＂Yánglíngquán＂（阳陵泉 GB 34） group and ＂Chéngjīn＂（承筋 BL 56） group, with five male rats and five female rats in each group. Acute gastric mucosal lesion model was established by applying WRS method. After successful modeling and treatment for ten days, sampling was conducted, gastric mucosal lesion was observed visually and scored, the levels of serum HMGB 1 and gastric tissue TNF-α were detected by ELISA method, and the expression of NF-κB was detected by immunohistochemical method. Results①Compared with the model group, the levels of Ulcers and inflammation（UI） in gastric mucosal and serum HMGB1, and the expression of gastric tissue TNF-α and NF-κB in the four lower he-sea points groups reduced（P〈0.01 or P〈0.05）;② compared with ST 36 group, the levels of gastric mucosal UI and serum HMGB1, and the expression of gastric mucosal TNF-α and NF-κB in other treatment groups increased significantly, and the difference was statistically significant（P〈0.01 or P〈0.05）. Conclusion①Electroacupuncture at relevant lower he-sea points can inhibit the body＇s immune response, relieve inflammatory reaction and reduce mucosal lesion by regulating HMGB 1, TNF-α and NF-κB, so as to realize the intervention and treatment on AGML rats;② the total intervention effect in ST 36 group is superior to that in other groups, indicating partially that there is a relative specificity between ST 36 and stomach.展开更多

文摘Objective To observe the efficacy difference of renal colic treated with electroacupuncture in comparison with intramuscular injection with Fortanodyn. Methods Fifty-one patients with renal colic were randomly divided into an electroacupuncture group （26 cases） and a medicine group （25 cases）. In the electroacupuncture group, electroacupuncture was applied to the Xi-cleft points of kidney and bladder meridians, named Shuǐquán （水泉 KI 5） and Jīnmén （金门 BL 63） as well as the relevant Front-mu points, Jīngmén （京门 GB 25） and Zhōngjí （中极 CV 3）. In the medicine group, intramuscular injection with Fortanodyn （100 mg） was administered. Once treatment was applied for immediate analgesia in each group. Before and after treatment, the Simplified McGill Pain Questionnaire （SF-MPQ） and the Visual Analogy Scale （VAS） were adopted for pain assessment respectively. The clinical efficacy and the recurrence of the disease were observed in the two groups. Results The clinically cured and remarkably effective rate was 69.2% （18/26） in the electroacupuncture group, which was superior to 44.0% （11/25） in the medicine group （P0.05）. Separately, in 10 min, 30 min, 60 min and 120 min after treatment, in either group, SF-MPQ and VAS scores were obviously reduced as compared with those before treatment （all P0.05）. The scores in 10 min and 30 min after treatment in the electroacupuncture group were reduced more remarkably as compared with those in the medicine group （both P0.05）. The complete remission time in the electroacupuncture group was shorter apparently than that in the medicine group [（131.19±152.12） min vs （184.29±84.04） min, P0.05]. The recurrence rate of renal colic in 24 h was 8.0% （2/25） in the electroacupuncture group, which was lower slightly than 31.6% （6/19） in the medicine group （P0.05）. Conclusion Renal colic can be effectively relieved in the treatment with either electroacupuncture at the Xi-cleft points and the Front-mu points of kidney and bladder meridians or intramuscular injection with Fortanodyn. But, the electroacupuncture therapy achieves much better efficacy.

文摘In the multilayer film-substrate system,thermal stress concentration and stress mutations cause film buckling,delamination and cracking,leading to device failure.In this paper,we investigated a multilayer film system composed of a substrate and three film layers.The thermal stress distribution inside the structure was calculated by the finite element method,revealing significant thermal stress differences between the layers.This is mainly due to the mismatch of the coefficient of thermal expansion between materials.Different materials respond differently to changes in external temperature,leading to compression between layers.There are obvious thermal stress concentration points at the corners of the base layer and the transition layer,which is due to the sudden change of the shape at the geometric section of the structure,resulting in a sudden increase in local stress.To address this issue,we chamfered the substrate and added an intermediate layer between the substrate and the transition layer to assess whether these modifications could reduce or eliminate the thermal stress concentration points and extend the service life of the multilayer structure.The results indicate that chamfering and adding the intermediate layer effectively reduce stress discontinuities and mitigate thermal stress concentration points,thereby improving interlayer bonding strength.

文摘OBJECTIVE: To investigate the effects of needling the Shu, Yuan, and Mu acupoints on serum uric acid(SUA), xanthine oxidase(XOD), and alkaline phosphatase(ALP) levels and the kidney index in a rat model of gout and hyperuricemia.METHODS: Fifty rats were randomly divided into five groups: blank, model, Shu-acupoint, Yuan-acupoint, and Mu-acupoint groups. A rat model of hyperuricemia was developed by intragastric administration of adenine and ethambutol. This experiment last for 90 d in total. Treatment groups underwent 3 courses of acupuncture. Each course involved a total of 10 interventions(one intervention every second day) with each intervention lasting15 min. There was a break for 10 d between courses. SUA and ALP were analyzed using an automatic biochemical analyzer and XOD was analyzed using immunofluorescence.RESULTS: Compared with the blank group, SUA and XOD levels in the model group were significantly higher and the renal index significantly improved. Compared with the model group, SUA and XOD levels in the three treatment groups decreased and the renal index significantly improved.When the three treatment groups were compared,the Mu-acupoint group showed the greatest decreases in SUA and XOD levels, followed by the Yuan-acupoint group. There was no significant difference in kidney index among the three treatment groups. There was no significant difference in ALP levels among the groups.CONCLUSION: The three treatments showed significantly reduced SUA and XOD levels compared with the control groups, possibly suggesting reduced renal damage.

文摘The success of robot-assisted pelvic fracture reduction surgery heavily relies on the accuracy of 3D/3D feature-based registration.This process involves extracting anatomical feature points from pre-operative 3D images which can be challenging because of the complex and variable structure of the pelvis.PointMLP_RegNet,a modified PointMLP,was introduced to address this issue.It retains the feature extraction module of PointMLP but replaces the classification layer with a regression layer to predict the coordinates of feature points instead of conducting regular classification.A flowchart for an automatic feature points extraction method was presented,and a series of experiments was conducted on a clinical pelvic dataset to confirm the accuracy and effectiveness of the method.PointMLP_RegNet extracted feature points more accurately,with 8 out of 10 points showing less than 4 mm errors and the remaining two less than 5 mm.Compared to PointNettt and PointNet,it exhibited higher accuracy,robustness and space efficiency.The proposed method will improve the accuracy of anatomical feature points extraction,enhance intra-operative registration precision and facilitate the widespread clinical application of robot-assisted pelvic fracture reduction.

文摘Ecosystems generally have the self-adapting ability to resist various external pressures or disturbances,which is always called resilience.However,once the external disturbances exceed the tipping points of the system resilience,the consequences would be catastrophic,and eventually lead the ecosystem to complete collapse.We capture the collapse process of ecosystems represented by plant-pollinator networks with the k-core nested structural method,and find that a sufficiently weak interaction strength or a sufficiently large competition weight can cause the structure of the ecosystem to collapse from its smallest k-core towards its largest k-core.Then we give the tipping points of structure and dynamic collapse of the entire system from the one-dimensional dynamic function of the ecosystem.Our work provides an intuitive and precise description of the dynamic process of ecosystem collapse under multiple interactions,and provides theoretical insights into further avoiding the occurrence of ecosystem collapse.

文摘Objectives: This study aimed to evaluate the prolonged therapeutic effects of a 35 kDa molecular weight hyaluronan fragment (HA35) in alleviating pain associated with myofascial pain syndrome (MPS). Hyaluronan interacts with various receptors in the human body, including CD44, LYVE-1, RHAMM, and TLR2, and is well-known for its analgesic effects when used in intra-articular or ultrasound-guided nerve trunk injections. Studies have shown that hyaluronidase cleaves high molecular weight HA to generate HA35, a low molecular weight fragment with enhanced tissue permeability, capable of binding to HA receptors on cell surfaces to produce broad-spectrum analgesic effects. Methods: Ten patients diagnosed with MPS were treated and assessed in this study. HA35 was administered through injection at a dosage of 100 mg daily for 15 days. Patients evaluated their MPS, overall pain levels, and treatment satisfaction using the Numerical Pain Rating Scale (NPRS), the Global Pain Scale (GPS), and the Treatment Satisfaction Questionnaire for Medication (TSQM 1.4). Follow-up evaluations were performed three months post-treatment to assess the duration of therapeutic effects. Results: Significant improvements were observed in NPRS, GPS, and TSQM scores both during and after the treatment period (P Conclusions: HA35 provides effective and sustained relief from pain associated with MPS, demonstrating a prolonged therapeutic benefit.

文摘In this paper, we investigate the effect of exceptional points(EPs) on the violation of Leggett–Garg inequality(LGI) and no-signaling-in-time(NSIT) conditions and compare the different effects between the Hamiltonian EP(HEP) and Liouvillian EP(LEP) on those violations. We consider an open system consisting of two coupled qubits and each qubit is contacted with a thermal bath at a different temperature. In the case of omitting quantum jumps, we find that the system exhibits a second-order HEP, which separates the parameter space into an overdamped regime and an underdamped regime. In this situation, the LGI and NSIT conditions can be violated in both regimes and not violated at the HEP. In the case of without omitting quantum jumps, we find that the system exhibits a third-order LEP, which also separates the parameter space into an overdamped regime and an underdamped regime. In this situation, the LGI can only be violated in the underdamped regime with large coupling strength between the qubits.Conversely, the NSIT conditions can be violated in both regimes, as well as at the LEP, except in the overdamped regime with small coupling strength between the qubits. Comparing the violations of the LGI and NSIT conditions with HEP and LEP, we find that the quantum jumps would reduce the generation of coherence, enhance the decoherence, and lead to narrower parameter regimes that the LGI and NSIT conditions can be violated. Furthermore, in both cases,the NSIT conditions can be violated in a wider parameter regime than the LGI.

文摘Background:The medicinal material known as Os Draconis(Longgu)originates from fossilized remains of ancient mammals and is widely used in treating emotional and mental conditions.However,fossil resources are nonrenewable,and clinical demand is increasingly difficult to meet,leading to a proliferation of counterfeit products.During prolonged geological burial,static pressure from the surrounding strata severely compromises the microstructural integrity of osteons in Os Draconis,but Os Draconis still largely retains the structural features of mammalian bone.Methods:Using verified authentic Os Draconis samples over 10,000 years old as a baseline,this study summarizes the ultrastructural characteristics of genuine Os Draconis.Employing electron probe microanalysis and optical polarized light microscopy,we examined 28 batches of authentic Os Draconis and 31 batches of counterfeits to identify their ultrastructural differences.Key points for ultrastructural identification of Os Draconis were compiled,and a new identification approach was proposed based on these differences.Results:Authentic Os Draconis exhibited distinct ultrastructural markers:irregularly shaped osteons with traversing fissures,deformed/displaced Haversian canals,and secondary mineral infill(predominantly calcium carbonate).Counterfeits showed regular osteon arrangements,absent traversal fissures,and homogeneous hydroxyapatite composition.Lab-simulated samples lacked structural degradation features.EPMA confirmed calcium carbonate infill in fossilized Haversian canals,while elemental profiles differentiated lacunae types(void vs.mineral-packed).Conclusion:The study established ultrastructural criteria for authentic Os Draconis identification:osteon deformation,geological fissures penetrating bone units,and heterogenous mineral deposition.These features,unattainable in counterfeits or modern processed bones,provide a cost-effective,accurate identification method.This approach bridges gaps in TCM material standardization and supports quality control for clinical applications.
文摘Dysphagia caused by true bulbar paralysis after stroke is a common and serious complication that severely affects patients’eating ability and quality of life,and significantly increases the risk of complications such as pneumonia and malnutrition.Electroacupuncture at swallowing points stimulates Swallowing 1 and Swallowing 2 acupoints,acting on key areas such as the glossopharyngeal nerve and vagus nerve,stimulating the reconstruction of nerve reflex arcs and the recovery of swallowing function.Therefore,this article analyzes the mechanism and clinical efficacy of electroacupuncture at swallowing points for the treatment of dysphagia caused by true bulbar paralysis after stroke,aiming to provide theoretical support and practical basis for clinical application.
文摘In 2004 and 2014,two monographs on hypobaric storage(LP)were published by Stanley P.Burg.Based on his theoretical framework and technological advancements,as well as the research and development of equipment conducted under his guidance,alongside customer practices and reflections on various scientific literature both domestically and internationally,it is posited that,as articulated in the monograph,misconceptions regarding his theory and technology in Western scientific literature prior to 1985 continue to persist.This ongoing dissemination of misunderstandings has resulted in a near stagnation of research and has adversely impacted the Chinese academic community as well.Consequently,it is essential to delineate the characteristics and main points of its theory and technology,with the aim of offering guidance to individuals seeking to comprehend its foundational purpose.LP technology is a dynamic physical technology that continuously and uninterruptedly extracts air from a closed container and simultaneously introduces fresh,low-pressure moist air from the external environment,while maintaining specific levels of humidity and/or temperature within the container and upholding a predetermined pressure value.Preservation technology is the collective term for the set of various technical parameters associated with preservation,including pressure,relative humidity,and other relevant factors,to which LP equipment is specifically designed.The theory of LP is characterized by the enhanced diffusion of gases and vapors that enter and exit the commodity in a dynamic manner under low pressure conditions.The theoretical points involve equipment performance,low pressure,the impact of trace concentrations of gases such as O_(2),CO_(2) and C_(2)H_(4) that naturally occur at low pressure,diffusive mass transfer,heat transfer,and impacts on the activity of enzymes associated with maturation and senescence.The technology is characterized by dynamic low pressure,and the range of commodities preserved is comparable to that of refrigeration.However,certain commodities exiting the hypobaric environment possess subsequent preservation advantages that are not available through refrigeration.The main points of the technology encompass an extended sotrage life,a postponement of quality degradation,minimized water loss,the suppression of pathogen growth,and the killing of both internal and external insects of the commodity under dynamic low pressure conditions.The core advantage of LP technology lies in its ability to significantly reduce water loss,inhibit respiration and C_(2)H_(4) action,and pathogen growth,killing insects and modulate the activity of enzymes associated with maturation and senescence in post-harvest fresh horticultural products.Consequently,this technology plays a crucial role in prolonging the post-harvest lifespan of these commodities and mitigating quality degradation.Over the past decade,researchers in China have developed a hypobaric short period treatment technology,grounded in LP theory and technical practice,which is commonly referred to as hypobaric treatment.This method has garnered significant attention,leading to an increase in both domestic and international research.A growing body of literature categorizes LP as hypobaric treatment,while some studies also consider vacuum packaging and modified atmosphere packaging(MAP)as LP or hypobaric treatment.Misunderstandings are exacerbated by confusion surrounding nomenclature,which,in conjunction with pre-existing misconceptions,represents a significant barrier to both the research and practical application of the technology.The successful commercial implementation of a vacuum cold fresh chain,centered on LP or hypobaric treatment technology,may be the sole solution to the prevailing misunderstandings associated with LP.

文摘The study delves into multiplicative contractions,exploring the existence and uniqueness of common fixed points for a weakly compatible pair of mappings.Those mappings adhere to specific multiplicative contraction conditions characterized by exponents expressed as fraction multiplicative metric spaces.It is noted that a metric can induce a multiplicative metric,and conversely,a multiplicative metric can give a rise to a metric on a nonempty set.As an application,another proof of the existence and uniqueness of the solution of a multiplicative initial problem is given.
文摘Objective To observe the clinical efficacy of threadembedding at the combined lower he-sea and front-mu points for functional constipation with intestinal excess heat.Methods A total of 80 patients with functional constipation of intestinal excess heat were randomly divided into a thread-embedding group(40 cases,2 cases dropped out)and a Chinese patent medication group(40 cases,1 case dropped out).Based on the theory of combined lower he-sea and front-mu points for diseases of fu organs,Zhongwan(CV12),Guanyuan(CV4)and bilateral Zusanli(ST36),Shangjuxu(ST37),Tianshu(ST25),Xiajuxu(ST39)were selected and threadembedding therapy was delivered in the thread-embedding group,once a week.Maren Runchang pll was given orally in the Chinese patent medication group,6-12 g each time,twice a day.Both groups were treated for 4 weeks.Before and after treatment,the scores of constipation assessment scale(CAS),Bristol stool form scale(BSFS),patient-assessment of constipation quality of life(PAC-QOL)and TCM syndrome were observed,and the clinical efficacy was evaluated after treatment in the two groups.Results After treatment,the CAS scores and the TCM syndrome scores were decreased compared with those before treatment(P<0.05),while the BSFS scores were increased compared with those before treatment(P<0.05)in the two groups;the total scores,as well as the physical discomfort and psychosocial discomfort scores of PAC-QOL were decreased compared with those before treatment(P<0.05)in the two groups,the worry and anxiety,and the satisfaction scores of PAC-QOL were decreased compared with those before treatment(P<0.05)in the thread-embedding group.After treatment,the CAS score,the total score and item-scores of PAC-QOL,as well as the TCM syndrome score in the thread-embedding groupwere lower than those in the Chinese patent medication group(P<0.05).The total effective rate was 78.9%(30/38)in the thread-embedding group,which was higher than 56.4%(22/39)in the Chinese patent medication group(P<0.05).Conclusion Thread-embedding at the combined lower he-sea and front-mu points can effectively treat functional constipation with intestinal excess heat and improve quality of life.

文摘Leaf turgor loss point has been recognized as an important plant physiological trait explaining a species’drought tolerance( π_(tlp)).Less is known about the variation of π_(tlp) in time and how seasonal or interannual differences in water availability are affecting π_(tlp) as a static trait.I monitored the seasonal variation of π_(tlp) during a drought year starting in early spring with juvenile leaves and assessed the interannual variation in π_(tlp) of fully matured leaves among years with diverting water availability for three temperate broad-leaved tree species.The largest seasonal changes in π_(tlp) occurred during leaf unfolding until leaves were fully developed and matured.After leaves matured,no significant changes occurred for the rest of the vegetation period.Interannual variation that could be related to water availability was only present in one of the three tree species.The results suggest that the investigated species have a rapid period of osmotic adjustment early in the growing season followed by a period of relative stability,when π_(tlp) can be considered as a static trait.

文摘Fractional discrete systems can enable the modeling and control of the complicated processes more adaptable through the concept of versatility by providing systemdynamics’descriptions withmore degrees of freedom.Numerical approaches have become necessary and sufficient to be addressed and employed for benefiting from the adaptability of such systems for varied applications.A variety of fractional Layla and Majnun model(LMM)system kinds has been proposed in the current work where some of these systems’key behaviors are addressed.In addition,the necessary and sufficient conditions for the stability and asymptotic stability of the fractional dynamic systems are investigated,as a result of which,the necessary requirements of the LMM to achieve constant and asymptotically steady zero resolutions are provided.As a special case,when Layla and Majnun have equal feelings,we propose an analysis of the system in view of its equilibrium and fixed point sets.Considering that the system has marginal stability if its eigenvalues have both negative and zero real portions,it is demonstrated that the system neither converges nor diverges to a steady trajectory or equilibrium point.It,rather,continues to hover along the line separating stability and instability based on the fractional LMM system.
