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 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.

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 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.

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 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.

Objective:To investigate the effect of insular involvement on the outcomes of patients with acute anterior circulation ischemic stroke.Methods:Patients with acute anterior circulation ischemic stroke admitted to the Department of Neurology, Nanjing Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University from January 2015 to December 2020 were retrospectively included. Demographic data, vascular risk factors, clinical and laboratory data, as well as treatment and outcomes were collected. Firstly, the correlation between the insular involvement and the outcomes was investigated, and then the bootstrap method was used to clarify the mediating role of infarct volume between the insular involvement and the poor outcomes.Results:A total of 450 patients with acute anterior circulation ischemic stroke were enrolled, among whom 79 cases (17.6%) had insular involvement and 41 (9.1%) had left insular involvement. There were 111 (24.7%) with poor outcomes, including 5 (1.1%) died. Compared to the non-insular involvement group, the insular involvement group had a higher proportion of patients with atrial fibrillation, shorter onset to door time, higher neutrophil-to-lymphocyte ratio (NLR), higher National Institutes of Health Stroke Scale (NIHSS) score at admission, larger infarct volume, and higher proportion of patients with poor outcomes (all P<0.05). In addition, patients with left insular involvement were younger than those with right insular involvement, had a higher baseline NIHSS score, a lower proportion of patients with minor stroke (NIHSS score ≤8), and had a longer onset to door time (all P<0.05). Compared to the good outcome group, the poor outcome group was older, with a higher proportion of female patients, higher systolic blood pressure, blood glucose, NLR, and NIHSS scores at admission, larger infarct volume, and a higher proportion of patients with insular involvement (all P<0.05). Mediation analysis suggested that the mediating effect of infarct volume between the insular involvement and the poor outcomes was significant (95% confidence interval 0.033-0.230; P=0.008). Conclusions:insular involvement in patients with acute anterior circulation ischemic stroke is associated with the poor outcomes, and this association may be mediated by infarct volume. Patients with left insular involvement may have more severe symptoms than those with right insular involvement, but there is no significant difference in the outcomes.
