OBJECTIVE:Neuromuscular exercise is a new comprehensive rehabilitation therapy in recent years,but its effect on knee osteoarthritis is still controversial.The purpose of this paper is to systematically evaluate the efficacy of neuromuscular exercise on knee osteoarthritis pain and function. METHODS:The randomized controlled trials addressing neuromuscular exercise in the treatment of knee osteoarthritis pain and function were retrieved from PubMed,Cochrane Library,Embase,EBSCO,CNKI,Web of Science,China Biomedical Database(CBM),VIP,and WanFang Database.The retrieval time ranged from database inception to October 2023.The neuromuscular training group(experimental group)was given neuromuscular training or neuromuscular training as the main intervention;the control group was a blank group or given conventional rehabilitation.Outcome indicators included the Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC)score,walking time,knee stability,and the maximum number of knee flexion in 30 seconds.The risk of bias was evaluated by the Cochrane Collaboration tool and the Physiotherapy Evidence Database.Meta-analysis was performed using RevMan 5.4 software. RESULTS:A total of 11 randomized controlled trials were included,and 628 samples were extracted.The results of Meta-analysis showed that the experimental group was superior to the control group in terms of WOMAC pain score[standardized mean difference(SMD)=0.38,95%confidence interval(CI):0.08-0.69,P=0.01],knee stability(SMD=0.57,95%CI:0.23-0.92,P=0.001),the maximum number of knee joint flexion in 30 seconds(SMD=0.35,95%CI:0.05-0.65,P=0.02),and WOMAC physical function score(SMD=-0.79,95%CI:-1.30 to-0.28,P=0.002).In both groups,walking speed was increased and walking ability was improved in patients with knee osteoarthritis,but there was no significant difference(walking time:SMD=-0.22,95%CI:-0.48-0.03,P=0.09). CONCLUSION:Neuromuscular exercise can effectively improve knee joint pain,enhance the stability of the knee joint,and promote functional recovery in patients with knee osteoarthritis.However,more high-quality randomized controlled trials are still needed to further confirm the research.

A 71-year-old male presented with esophageal cancer and severe aortic valve regurgitation. Treatment strategies for such patients are controversial. Considering the risks of cardiopulmonary bypass and potential esophageal cancer metastasis, we successfully performed transcatheter aortic valve implantation and minimally invasive three-incision thoracolaparoscopy combined with radical resection of esophageal cancer (McKeown) simultaneously in the elderly patient who did not require neoadjuvant treatment. This dual minimally invasive procedure took 6 hours and the patient recovered smoothly without any surgical complications.

Objective To explore the underlying mechanisms by which time-restricted feeding(TRF)attenuates dextran sodium sulfate(DSS)-induced colitis in mice via modulation of regenerating islet-derived protein 3 gamma(Reg3γ)expression and gut microbiota.Methods Six-week-old C57BL/6 mice were stratified by body weight and randomized into ad libitum feeding(AL)and TRF groups(n=7).The AL mice were given unrestricted food access,whereas the TRF mice were allowed feeding only during 00:00 and 08:00 daily,for totally 4 weeks.Mouse colitis model was induced at the fourth week by adding 2.5%dextran sodium sulfate(DSS)in drinking water for 6 d.Disease severity and the effects of TRF were assessed with disease activity index(DAI)scoring,colon length measurement,HE staining and histopathological scoring,and mRNA expression levels of regenerating islet-derived 3 gamma(Reg3g)and inflammatory cytokines in colonic tissues.Another 14 mice were randomized into AL plus antibiotic cocktail(AL+ABX)and TRF plus antibiotic cocktail(TRF+ABX)groups,with 7 animals in each group.ABX was administered to deplete gut microbiota and evaluate the microbiota dependence of TRF in attenuating colitis.Fecal samples from AL and TRF mice were analyzed by 16S ribosomal RNA sequencing(16S rRNA-seq),and serum lipopolysaccharide(LPS)level was measured.The colonic epithelial cells were collected for RNA-seq.Results After modeling,the AL mice exhibited typical colitis symptoms,such as weight loss,diarrhea,and hematochezia.TRF intervention significantly attenuated these above symptoms,with lower DAI scores from day 4 post-modeling(P<0.001),reduced colon shortening(P<0.01),preserved tissue architecture,and decreased inflammation.RT-qPCR analysis showed that TRF down-regulated colonic mRNA expression levels of Reg3g and pro-inflammatory cytokines(IL-1 β,IL-6,TNF-α)(P<0.05)while up-regulated that of anti-inflammatory factor IL-10(P<0.000 1)when compared with the corresponding levels in AL mice.ABX treatment led no significant differences between the AL+ABX and TRF+ABX groups in term of DAI score,colon length,or histopathology.Obviously down-regulated Reg3g was observed in the TRF+ABX group than the AL+ABX group(P<0.05),whereas L-1β,IL-6,TNF-α and IL-10 showed no notable changes.16S rRNA-seq revealed that TRF markedly reshaped gut microbiota composition,with increased Gram-positive bacterial abundance,reduced Gram-negative bacteria,with concomitant lower serum LPS level(P<0.001).RNA-seq also indicated significant suppression of NF-κB and other inflammation-related signaling pathways in the TRF group.Conclusion TRF attenuates DSS-induced colitis in mice by downr-egulating Reg3γ expression,reshaping gut microbiota,and reducing serum LPS level,and thereby suppressing NF-κB-mediated inflammatory signaling pathways.

Objective:To evaluate the clinical efficacy and impact on quality of life of the biofeedback (BF) therapy combined with the Wenyang Yiqi Prescription and self-efficacy interventions in patients with functional defecation disorders (FDD).Methods:A prospective, randomized controlled trial design was employed. A total of 128 FDD patients were selected from the Pelvic Floor Center of the Department of Proctology, Suzhou Traditional Chinese Medicine Hospital Affiliated to Nanjing University of Chinese Medicine, between January 2021 and April 2023. These patients were randomly divided into two groups, with 64 cases in each group. Additionally, 41 historical control patients, who had received conventional BF training between June 2015 and January 2018 at the same center, were included for comparison. The historical control group received conventional BF therapy, the intervention group 1 combined BF therapy with self-efficacy interventions, and the intervention group 2 added the Wenyang Yiqi Prescription based on intervention group 1's treatment. All three groups underwent two treatment courses. Constipation symptom scores before and after treatment were performed; self-efficacy was assessed via the Self-Rated Abilities for Health Practices scale (SRAHP); health behaviors were evaluated using the Health-Promoting Lifestyle Profile (HPLP); anxiety and depression were evaluated through Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS); quality of life was measured through SF-36. Clinical efficacy was evaluated based on constipation symptom scores.Results:During the treatment period, seven patients dropped out due to personal reasons, leaving 61 patients in intervention group 1 and 60 patients in intervention group 2 for efficacy analysis.　The total effective rates were 80.32% (49/61) in intervention group 1, 83.33% (50/60) in intervention group 2, and 56.10% (23/41) in the historical control group. The total effective rates of both intervention groups were significantly higher than those in the historical control group ( χ2=7.06, 9.15; P=0.029, 0.010, respectively). After treatment, intervention group 2 showed significantly lower constipation-related straining scores [1 (1, 2) vs. 2 (1, 2), Z=-4.51] compared to intervention group 1 ( P<0.05). Additionally, intervention group 2 had lower scores for straining [1 (1, 2) vs. 2 (1, 2), Z=-3.15] and defecation time [1 (0, 1) vs. 1 (1, 2), Z=-3.13] compared to the historical control group ( P<0.05). Psychological comfort efficacy (19.13 ± 2.51 vs. 16.98 ± 1.86, t=5.36), health responsibility efficacy (23.63 ± 4.69 vs. 22.59 ± 3.05, t=2.06), and overall SRAHP scores (75.98 ± 4.44 vs. 72.33 ± 5.16, t=4.17) were higher in intervention group 2 compared to intervention group 1 ( P<0.05). The HPLP scores (79.33 ± 11.13 vs. 72.80 ± 9.20, t=3.10) of intervention group 2 were higher than those of the historical control group ( P<0.05). Emotional functioning scores (75.98 ± 18.45 vs. 68.92 ± 20.58 and 68.55 ± 18.21, F=20.91) in intervention group 2 were higher than in both intervention group 1 and the historical control group ( P<0.05). Conclusion:The combination of the Wenyang Yiqi Prescription with BF therapy and self-efficacy interventions effectively improves the clinical symptoms and quality of life in FDD patients.

Objective:To understand the prevalence and characteristics of Rhinovirus (HRV) infection in influenza-like Illness (ILIs) patients in Mianyang, Sichuan province, China.Methods:Throat swabs were collected from patients of ILIs in sentinel hospitals in Mianyang during 2021—2022. Real-time fluorescence quantitative PCR was used to detect 16 common pathogens. The VP4/VP2 coding region genes of HRV positive samples were amplified by nest PCR. The phylogeny, consistency and amino acid variation of different serotypes were analyzed and compared with reference sequences from GenBank database.Results:A total of 332 ILIs′ samples were collected with a virus detection rate of 58.73% (195/332) in Mianyang. Among them, 23 samples (23/332) were HRV-positive, and 18 VP4/VP2 sequences of HRV strains were successfully amplified. It was found that 13 HRV serotypes were detected in ILIs samples in Mianyang, which belonged to three genotypes, namely HRV-A (12 strains), HRV-B (5 strains) and HRV-C (1 strain).Conclusions:HRV was one of the pathogens of ILIs cases in Mianyang during 2021—2022, with HRV-A types as the dominant strains.

Objective To observe the effect of cognitive behavioural therapy for insomnia(CBT-I)combined with stellate ganglion block(SGB)on insomnia after corona virus disease-2019(COVID-19).Methods Eighty-four patients with insomnia after COVID-19 were selected from the anesthesia sleep clinic,26 males and 58 females,aged 18-64 years,BMI 20-32 kg/m2.The patients were randomly divid-ed into two groups:CBT-I combined with SGB(group S)and CBT-I(group C),42 patients in each group.Both groups of patients underwent the same CBT-I regimen for 6 weeks.Patients in group S underwent SGB alternately on both sides every day in the first week,inject 3 ml of 1%lidocaine,1 ml of vitamin B1(50 mg),and 1 ml of vitamin B6(50 mg),totaling 5 ml,and SGB was performed once a week from week 2 to week 6,for a total of 12 times.Group C patients cannot undergo SGB.Record the Pittsburgh sleep quality index(PSQI)scores of patients before treatment,6 weeks,3 months,and 6 months after treatment.Record the insomnia severity index(ISI),Athens insomnia scale(AIS)scores,and serum concentrations of cortisol(Cor)and serotonin(5-HT)before and 1 week and 6 weeks after treatment.Record the patient's compliance with the treatment plan.Results Compared with before treatment,the PSQI scores of the two groups of patients significantly decreased at 6 weeks,3 months,and 6 months after treatment(P＜0.05),the ISI score,AIS score,and serum Cor concentration in group S were significantly reduced after 1 week and 6 weeks of treatment(P＜0.05),while the serum 5-HT concentration was significantly increased(P＜0.05),the ISI score,AIS score,and serum Cor concentration in group C were significantly reduced after 6 weeks of treatment(P＜0.05),while the serum 5-HT concentration was significantly increased(P＜0.05).Compared with group C,patients in group S showed a significant decrease in PSQI scores 6 weeks after treatment(P＜0.05),the ISI score,AIS score,and serum Cor concentration in group S were signifi-cantly reduced after 1 week and 6 weeks of treatment(P＜0.05),while the serum 5-HT concentration was significantly increased(P＜0.05),patients in group S showed a significant increase in adherence to the treatment plan(P＜0.05).Conclusion CBT-I combined with SGB can improve short-term sleep quality after COVID-19,and improve patients'compliance with the treatment plan.

Fascia,the initial response site for mechanical stimulation in manipulations,is also the target of the effect of manipulations.As the essence of manipulation is"force",how mechanical stimuli are transduced into neuroelectric and biochemical signals in the fascia and how physical and chemical signals of the fascia initiate the mechanical stimulation effect are the common key questions in the study of the principle of manipulation.The physical changes in the fascial connective tissue caused by the manipulation,such as the deformation and displacement of the fascial tissue,can act on the nerve end receptors in the fascial layer and generate neural electrical signals;they can also activate the mechanoreceptors on the fascial cell membrane and convert mechanical signals into chemical signals via mechanosensitive ion channel transduction,triggering a physicochemical coupling response in the fascial microenvironment and producing mechanical stimulation through neuro-endocrine-immune system pathways.The"mechanical force of manipulation"in the fascia is transmitted through the meridian to facilitate the body's perception and transmission of mechanical stimulation signals,indicating that the fascia is the"sensor"of coupled response to the physicochemical information of mechanical stimulation of manipulation.

OBJECTIVE:At present,there are a variety of treatment methods for scoliosis using specific exercise therapy,but there is a lack of comparison of efficacy between different specific exercise therapy.This article compared the effectiveness of different specific exercise therapies to treat adolescent idiopathic scoliosis through a network meta-analysis. METHODS:Domestic and foreign electronic databases of relevant studies were searched for randomized controlled trials of specific exercise therapy for adolescent idiopathic scoliosis.Search time was from January 2000 to July 2023.The literature was screened by two reviewers using RevMan 5.4 and Stata 16.0 software to extract data and assess the bias risk of of inclusion studies. RESULTS:(1)This article includes 20 randomized controlled trials with 1 377 patients.Of them,12 studies involved Schroth therapy;2 studies involved BSPTS therapy,and 6 studies involved SEAS therapy.(2)The network meta-analysis indicated that in terms of improving Cobb angle and reducing trunk rotation angle in scoliosis patients,the BSPTS therapy group and Schroth therapy group were better than the conventional control group[WMD=-4.60,95%CI(-8.37,-0.82),P<0.05;WMD=-3.37,95%CI(-4.98,-1.75),P<0.05;WMD=-3.20,95%CI(-5.50,-0.90),P<0.05;WMD=-2.13,95%CI(-3.16,-1.09),P<0.05].The Schroth therapy group performed better than the conventional control group effective in improving the International Society for Scoliosis Research-22 Questionnaire quality of life score[WMD=1.41,95%CI(0.07,2.75),P<0.05]. CONCLUSION:Given the current evidence,BSPTS therapy group and Schroth therapy group were better than the conventional control group in improving Cobb angle and reducing trunk rotation angle.In the comparison of different specific exercise therapies,BSPTS therapy can be preferred to improve Cobb angle and reduce trunk rotation angle in adolescent idiopathic scoliosis patients.In addition,Schroth therapy may be the best treatment to improve the quality of life of adolescent idiopathic scoliosis patients.Limited by the quantity and quality of the included studies,the above conclusions should be interpreted with caution and need more high-quality studies to further validation.

Objective:To explore the mechanism of peritoneal dialysis solution (PDS)-induced peritoneal microinflammation through activation of ceramide (CER) in peritoneal dialysis model mice.Methods:Thirty 5-week-old male C57BL/6 mice weighing about 22 g were used to set up peritoneal dialysis models, and then were randomly divided into 4 groups: sham operation group (1.5 ml sterilized water, n=7), high glucose-PDS group (1.5 ml 4.25% PDS, n=8), high glucose-PDS+ acid sphingomyelinase (ASMase) inhibitor desipramine (DES) group (1.5 ml sterilized water+10 mg/kg DES, n=8), high glucose-PDS+Src kinase inhibitor PP2 group (1.5 ml sterilized water +1 mg/kg PP2, n=7), with intraperitoneal injection once a day. After 28 days, the mice were sacrificed to retain peritoneal tissues. HE staining and Masson staining were used to observe the histological changes of peritoneum. Immunohistochemistry was used to detect the Toll-like receptor 4 (TLR4) and macrophages. High performance liquid chromatography, liquid chromatography/mass spectrometry and immunofluorescence were used to detect the expression of ASMase and CER. Real-time quantitative PCR was used to detect the mRNA levels of c-Src, p-Src, interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α). Western blotting was used to detect the protein levels of c-Src, and p-Src. Enzyme-linked immunosorbent assay was used to detect the serum C reactive protein (CRP), IL-6 and TNF-α. Results:(1) High glucose-PDS led to peritoneal hyperplasia, collagen deposition and fibrosis in the peritoneal dialysis mice, indicating successful modeling. Compared with high glucose-PDS group, peritoneal hyperplasia, collagen deposition and fibrosis of mice treated with DES and PP2 were significantly improved (all P<0.05). (2) Compared with sham operation group, ASMase activation and CER level of peritoneal tissues were significantly higher in high glucose-PDS group, and DES could significantly inhibit activated ASMase and increased CER expression caused by high glucose-PDS (both P<0.05). PP2 had no significant effect on ASMase activation and CER level (both P>0.05). (3) Compared with sham operation group, there were more TLR4 and macrophage positive staining cells in peritoneal tissues in high glucose-PDS group, and the mRNA expression levels of IL-6 and TNF-α in peritoneal tissues and serum CRP, IL-6 and TNF-α were higher (all P<0.05). DES and PP2 could significantly inhibit the increased TLR4, macrophages and related inflammatory factors induced by high glucose-PDS (all P<0.05). (4) Compared with sham operation group, c-Src and p-Src mRNA and protein expression levels of peritoneal tissues in high glucose-PDS group were significantly higher (all P<0.05). PP2 significantly inhibited the increased p-Src mRNA and protein levels caused by high glucose-PDS (both P<0.05), but had no significant effect on the mRNA and protein expression levels of c-Src (both P>0.05). DES had no significant effect on the mRNA and protein expression levels of c-Src and p-Src (all P>0.05). Conclusions:High glucose-PDS may enhance the expression of CER through stimulating the activity of ASMase, phosphorylate Src, activate TLR4 and induce inflammatory damage of peritoneum in peritoneal dialysis model mice.

Objective:To investigate the etiology of hand, foot and mouth disease (HFMD) in Mianyang city in 2022, and to analyze the genetic characteristics of coxsackievirus A6.Methods:Pharyngeal swabs were collected from patients with HFMD in Mianyang city in 2022. Real-time fluorescence quantitative PCR was used to detect enteroviruses in the samples. Part of the VP1 gene in enterovirus-positive samples was amplified by nested PCR using enterovirus typing primers to further identify the viral types. The VP1 coding region of all CVA6-positive samples and the whole genome of some samples were amplified and sequenced by PCR. The endemic strain in Mianyang city was analyzed for phylogeny, gene homology, amino acid variation and genetic recombination.Results:A total of 151 pharyngeal swabs were collected, and 104 enterovirus-positive samples were detected by real-time fluorescence quantitative PCR, with an overall detection rate of 68.88% (104/151). The typing results showed that there were 77 cases of CVA6 infection, with a positive rate of 50.99% (77/151). The full-length VP1 genes of 77 CVA6 strains were amplified, sequenced, and successfully spliced, and phylogenetic analysis showed that all 77 strains were of the D3 genotype. There were multiple amino acid variant sites in the prevalent strains in Mianyang city compared with the reference strain. Twenty whole genome sequences were amplified, sequenced, and successfully spliced, and homology analysis showed that the nucleotide homology between the 20 positive sequences ranged from 97.0% to 99.9%. Phylogenetic tree and recombination analysis showed that no recombination occurred in the coding regions of the epidemic strains in this study.Conclusions:The predominant pathogen causing HFMD in Mianyang city in 2022 is CVA6 D3 subtype, which is consistent with the national epidemic in 2022.
