BACKGROUND The effectiveness of Platelet-Rich Plasma(PRP)in the treatment of patients with Achilles tendon rupture(ATR)and Achilles tendinopathy(AT)has been controversial.AIM To assess PRP injections’effectiveness in treating ATR and AT.METHODS A comprehensive review of relevant literature was conducted utilizing multiple databases such as Cochrane Library,PubMed,Web of Science,Chinese Science and Technology Journal,EMBASE,and China Biomedical CD-ROM.The present investigation integrated randomized controlled trials that assessed the effectiveness of platelet-rich plasma injections in managing individuals with Achilles tendon rupture and tendinopathy.The eligibility criteria for the trials encompassed publications that were published within the timeframe of January 1,1966 to December 2022.The statistical analysis was performed utilizing the Review Manager 5.4.1,the visual analogue scale(VAS),Victorian Institute Ankle Function Scale(VISA-A),and Achilles Tendon Thickness were used to assess outcomes.RESULTS This meta-analysis included 13 randomized controlled trials,8 of which were randomized controlled trials of PRP for AT and 5 of which were randomized controlled trials of PRP for ATR.PRP for AT at 6 wk[weighted mean difference(WMD)=1.92,95%CI:-0.54 to 4.38,I2=34%],at 3 mo[WMD=0.20,95%CI:-2.65 to 3.05,I2=60%],and 6 mo[WMD=2.75,95%CI:-2.76 to 8.26,I2=87%)after which there was no significant difference in VISA-A scores between the PRP and control groups.There was no significant difference in VAS scores between the PRP group and the control group after 6 wk[WMD=6.75,95%CI:-6.12 to 19.62,I2=69%]and 6 mo[WMD=10.46,95%CI:-2.44 to 23.37,I2=69%]of treatment,and at mid-treatment at 3 mo[WMD=11.30,95%CI:7.33 to 15.27,I2=0%]after mid-treatment,the PRP group demonstrated better outcomes than the control group.Post-treatment patient satisfaction[WMD=1.07,95%CI:0.84 to 1.35,I2=0%],Achilles tendon thickness[WMD=0.34,95%CI:-0.04 to 0.71,I2=61%]and return to sport[WMD=1.11,95%CI:0.87 to 1.42,I2=0%]were not significantly different between the PRP and control groups.The study did not find any statistically significant distinction between the groups that received PRP treatment and those that did not,regarding the Victorian Institute of Sport Assessment-Achilles scores at 3 mo[WMD=-1.49,95%CI:-5.24 to 2.25,I2=0%],6 mo[WMD=-0.24,95%CI:-3.80 to 3.32,I2=0%],and 12 mo[WMD=-2.02,95%CI:-5.34 to 1.29,I2=87%]for ATR patients.Additionally,no significant difference was observed between the PRP and the control groups in improving Heel lift height respectively at 6 mo[WMD=-3.96,95%CI:-8.61 to 0.69,I2=0%]and 12 mo[WMD=-1.66,95%CI:-11.15 to 7.83,I2=0%]for ATR patients.There was no significant difference in calf circumference between the PRP group and the control group after 6 mo[WMD=1.01,95%CI:-0.78 to 2.80,I2=54%]and 12 mo[WMD=-0.55,95%CI:-2.2 to 1.09,I2=0%]of treatment.There was no significant difference in ankle mobility between the PRP and control groups at 6 mo of treatment[WMD=-0.38,95%CI:-2.34 to 1.58,I2=82%]and after 12 mo of treatment[WMD=-0.98,95%CI:-1.41 to-0.56,I2=10%]there was a significant improvement in ankle mobility between the PRP and control groups.There was no significant difference in the rate of return to exercise after treatment[WMD=1.20,95%CI:0.77 to 1.87,I2=0%]and the rate of adverse events[WMD=0.85,95%CI:0.50 to 1.45,I2=0%]between the PRP group and the control group.CONCLUSION The use of PRP for AT improved the patient’s immediate VAS scores but not VISA-A scores,changes in Achilles tendon thickness,patient satisfaction,or return to sport.Treatment of ATR with PRP injections alone improved long-term ankle mobility but had no significant effect on VISA-A scores,single heel lift height,calf circumference or return to sport.Additional research employing more extensive sampling sizes,more strict experimental methods,and standard methodologies may be necessary to yield more dependable and precise findings.

Systematic Evaluation of Deep Neural Network based Dynamic Modeling Method for AC Power Electronic System

Since the high penetration of renewable energy complicates the dynamic characteristics of the AC power electronic system(ACPES),it is essential to establish an accurate dynamic model to obtain its dynamic behavior for ensure the safe and stable operation of the system.However,due to the no or limited internal control details,the state-space modeling method cannot be realized.It leads to the ACPES system becoming a black-box dynamic system.The dynamic modeling method based on deep neural network can simulate the dynamic behavior using port data without obtaining internal control details.However,deep neural network modeling methods are rarely systematically evaluated.In practice,the construction of neural network faces the selection of massive data and various network structure parameters.However,different sample distributions make the trained network performance quite different.Different network structure hyperparameters also mean different convergence time.Due to the lack of systematic evaluation and targeted suggestions,neural network modeling with high precision and high training speed cannot be realized quickly and conveniently in practical engineering applications.To fill this gap,this paper systematically evaluates the deep neural network from sample distribution and structural hyperparameter selection.The influence on modeling accuracy is analyzed in detail,then some modeling suggestions are presented.Simulation results under multiple operating points verify the effectiveness of the proposed method.

Systematic evaluation of the efficacy and safety of botulinum toxin type A in the treatment of spastic cerebral palsy

Background:Botulinum toxin type A(BTX-A)is a neuromuscular blocking agent.BTX-A inhibits acetylcholine release,causes neuromuscular transmission impairment,and decreases muscle spasms.Objective:To explore the efficacy and safety of BTX-A injection in the treatment of spastic cerebral palsy through systematic evaluation and to provide a reference for the clinical use of BTX-A.Methods:We used“Cerebral palsy”and“BTX-A”as the subject terms and used a combination of subject terms and free words for the search.We searched 7 databases,including CNKI,Wanfang,VIP,Sinomed,PubMed,Embase,and Web of science.Based on the inclusion and exclusion criteria,we screened the articles by reading their titles,abstracts,and full texts and finally included relevant literature for systematic evaluation.Result:A total of 93 papers were systematically evaluated,revealing that BTX-A injection treatment can effectively reduce muscle tone,increase joint mobility,improve gait and motor posture,and enhance gross motor movements in patients with spastic cerebral palsy.The benefits of BTX-A treatment can be sustained for 3–6 months,with motor ability improvement lasting up to 1 year.Combining BTX-A treatment with rehabilitation or external fixation therapy can enhance its efficacy.However,the effectiveness of BTX-A treatment is influenced by several factors,such as the dosage,number of injections,and patient age.Adverse reactions to BTX-A treatment are typically mild and can be relieved within 1–2 weeks.Conclusion:BTX-A injection is relatively safe but reversible.

BACKGROUND：To evaluate the quality of the literature addressing traditional Chinese medicine for treating Parkinson＇s disease.DATA SOURCE：A computer-based online search of Chinese publications from January 2001 to July 2008 was conducted in Chinese Biology Medical Disc Database and China National Knowledge Infrastructure. Search key words were Parkinson＇s disease, integrated traditional Chinese and Western medicine, traditional Chinese medicine therapy, and Chinese herb therapy.DATA SELECTION：Articles describing randomized, controlled trials and quasi-randomized, controlled trials were included. Literature quality was assessed using the criteria-Systematic evaluation of clinical literature related to treatment of Parkinson＇s disease with traditional Chinese medicine. This included methodology, interventions in the treatment/control group, evaluation criterion of outcomes, and frequency.MAIN OUTCOME MEASURES：Evaluation criterion of outcomes （various score methods and evaluation scales）, methodological quality, and frequency distribution were all measured.RESULTS：A total of 33 articles with randomized, controlled trials were included. Of these, six described a random method, and the remaining did not describe random allocation methods or random sequence generation methods. None of the studies estimated sample size. Case descriptions of withdrawal and loss to follow-up were unclear. Both the Unified Parkinson＇s Disease Rating Scale and Webster scale were used in the eligible studies as evaluation criteria.CONCLUSION：There are no high-quality studies that address traditional Chinese medicine therapy and integrated traditional Chinese and Western medicine for treating Parkinson＇s disease in China. Eligible studies were not performed in accordance with Consolidated Standards of Reporting Trials statement or Standards for Reporting Interventions in Controlled Trials of Acupuncture criteria, and the literature quality was low. The presently used criteria for evaluating therapeutic effects do not completely assess outcomes of traditional Chinese medicine for treating Parkinson＇s disease. The identification of precise outcomes should be verified using randomized, controlled studies with adequate controls and proper designs.
