Objective:To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults.Methods:A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test.Results:A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95% CI: 2.23-3.88) points ( P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95% CI: 4.03-5.37) points ( P<0.001). Ba Duan Jin showed significant improvement ( P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions:This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.

【Objective】 To compare the risk of generalization in patients with ocular myasthenia gravis (OMG) receiving or not receiving immunosuppressive treatment. 【Methods】 The data of patients with OMG registered in Tangdu Hospital of Air Force Military Medical University from January 1, 2015 to May 1, 2019 were reviewed; the patients were divided into treatment group and control group according to whether they had received immunosuppressive treatment. The multivariate Cox proportional hazards regression model analysis was used to compare the risk of generalization between the two groups of patients within 2 years of onset. Sensitivity analysis was used to evaluate the duration of immunosuppressive treatment and the risk of generalization under different immunotherapy regimens. By using stratified analysis, the consistency of the main results across different levels of subgroup factors was evaluated. 【Results】 A total of 702 OMG patients were collected. Of them 367 patients (52.3%) were included in the treatment group, with an average onset age of (50.54±15.1) years, and 159 (43.3%) being female. Another 335 patients (47.7%) were included in the control group, with an average age of (49.1±14.6) years, and 159 ones (47.5%) were female. A total of 28 cases (7.7%) in the treatment group and 106 cases (31.6%) in the control group developed generalization during the observation period. After multivariate-adjusted Cox model analysis, patients who had received immunosuppressive treatment had a significantly lower risk of generalization compared with the control group (HR=0.24; 95% CI: 0.15-0.37; P<0.001). Sensitivity analysis found that the longer the duration of immunosuppression, the lower the risk of generalization (HR=0.88; 95% CI: 0.85-0.91; P<0.001). Stratified analysis showed that immunosuppressive therapy reduced the risk of generalization in different subgroups of patients. 【Conclusion】 Early immunosuppressive treatment can significantly reduce the risk of generalization in patients with OMG.

Objective To investigate the expression of pepsin in vocal cord polyps and vocal cord cancer,and to compare the difference of pepsin expression.Methods From May 2020 to December 2021,27 patients with vocal cord polyp,27 patients with vocal cord cancer and 23 healthy volunteers were selected.RSI and RFS scoring scales were used for scoring,pepsin detection kit was used for saliva pepsin detection,and immunohistochemical methods were used to detect the expression of pepsin in vocal cord tissues of patients with vocal cord polyps and vocal cord cancer.Results The RSI score,RFS score and pepsin test kit results of vocal cord polyp group and vocal cord canc-er group were higher than those of non-vocal cord disease group,and the differences of the three indexes were statis-tically significant(P＜0.05).RSI score,pepsin detection kit results and pepsin immunohistochemistry results of vocal cord polyp group showed no significant difference compared with vocal cord cancer group(P＞0.05).The RFS score of vocal cord polyp group was significantly different from that of vocal cord cancer group(P＜0.05).Conclusion Pepsin may be an important pathogenic factor of vocal cord polyp and vocal cord cancer,and play an im-portant role in the occurrence of these two diseases.The difference of pepsin expression in vocal cord polyp and vo-cal cord cancer suggests that pepsin may have different pathogenesis.

Gynecological diseases are one of the important factors that threaten women's reproductive health.Endoplasmic reticulum(ER)stress is a stress response induced by the accumulation of unfolded or misfolded proteins in ER cavity when the female body is in a disease state,and the effects of different stress levels on the female reproductive system and the increase in the risk of female disease will vary greatly.Studies have shown that ER stress is closely related to the occurrence and development of gynecological diseases.Based on the relevant research reports at home and abroad in recent years,this paper summarizes the role of ER stress in several common gynecological diseases to provide new research ideas for preventing,diagnosing,and treating gynecological diseases.

Objective To compare different treatment methods for patients with gastric calculi and provide data support for clinical treatment.Methods A total of 197 patients diagnosed with gastric calculi by gastroscopy at the General Hospital of Ningxia Medical University and Cardio-Cerebrovascular Disease Hospital of General Hospital of Ningxia Medical University from July 2013 to January 2024 were enrolled.The study collected general information and other data of the patients,and divided them into groups based on the selected treatment method using a real-world research approach.The subjects were divided into four groups:drug conservative treatment group,endoscopic homemade snare treatment group,disposable snare treatment group,and stone fragmentation treatment group.Statistical analysis was performed using one-way analysis of variance.Results Gastric calculi were more common in men,with an average age of(55.45±14.21).85.3%of the patients had a history of eating persimmon,86.3%had ulcers,and 65.9%were located in the gastric angle.The self-made snare group had the lowest treatment cost,while the stone fragmentation group had the highest.There was no significant difference in the remission time of clinical symptoms among the three endoscopic treatment methods.The self-made snare had the highest patient satisfaction,but the drug combined with carbonated beverage group had the longest remission time of clinical symptoms and the lowest patient satisfaction.The frequency and duration of endoscopic treatment of dark green gastric stones were significantly higher than those of mottled and golden yellow gastric stones.Conclusion When treating patients with gastric stones,it is important to consider the size and color of the stone,as well as the patient's preferences.Patients should be fully informed about their condition and the advantages of different treatments.For patients with larger stones(about 5 cm),endoscopic snare treatment is recommended as the first choice.

OBJECTIVE To observe the clinical efficacy of Huatan Tongluo Decoction in the treatment of post-stroke cognitive impairment(PSCI)with phlegm stasis obstructing collaterals syndrome,and its influence on the serum brain-derived neurotrophic fac-tor(BDNF)pathway-related factors.METHODS Sixty patients who met the inclusion criteria were collected and randomly divided into a control group and a treatment group with 30 patients each.The control group was given basic treatment and nimodipine,while the treatment group was given Huatan Tongluo Decoction on the basis of the treatment in the control group.The treatment course for both groups was 4 weeks.Changes in Mini-Mental State Examination(MMSE),TCM syndrome scores and serum levels of BDNF,nuclear transcription factor κB(NF-κB),B lymphocyte tumor-2(Bcl-2)and Bcl-2-associated X protein(Bax)were compared between the two groups before and after treatment.The TCM clinical efficacy in the two groups of patients was evaluated after treatment,and the oc-currence of adverse reactions was observed during treatment.RESULTS After treatment,the MMSE scores of the patients in the two groups increased significantly,the total TCM syndrome scores decreased significantly(P<0.01),and the treatment group was better than the control group(P<0.01);the serum BDNF,NF-κB,and Bcl-2 levels of the two groups of patients were significantly in-creased(P<0.05,P<0.01),and the Bax level was significantly decreased(P<0.01).The treatment group was better than the control group(P<0.01).CONCLUSION Huatan Tongluo Decoction can improve the clinical symptoms of PSCI patients with phlegm stasis obstructing collaterals,and is safe and effective.Its therapeutic mechanism may be related to regulating the BDNF pathway to protect nerve cells and inhibit nerve cell apoptosis.

Objective To analyze the clinical efficacy and safety of glecaprevir/pibrentasvir in the treatment of pa-tients with hepatitis C virus(HCV)and human immunodeficiency virus(HIV)co-infection,and provide scientific basis for clinical treatment.Methods 89 initially treated non-cirrhotic patients with HCV/HIV co-infection in a hospital of Butuo County of Liangshan Prefecture from January 2021 to January 2022 were selected.All patients re-ceived glecaprevir/pibrentasvir treatment for 8 weeks and were followed up for 12 weeks.Virological response rate at the end-of-treatment and sustained virological response rate after 12 weeks(SVR12)of treatment as well as oc-currence of adverse reaction were recorded.Results Among 89 initially treated non-cirrhotic patients with HCV/HIV co-infection,most were middle-aged and young married men(n=79,88.8％).HIV was mainly transmitted through sexual contact(n=62,69.7％)and intravenous drug use(n=27,30.3％).The most common HCV geno-types were genotype 1b(n=33,37.1％)and genotype 3b(n=25,28.1％).All patients completed 8 weeks of treatment successfully and HCV RNA load at the end of treatment was below the detection limit(＜25 IU/mL).Eight patients failed to complete the follow-up,and the remaining 81(100％)patients achieved a sustained virologic re-sponse.There were no serious adverse reactions during the observation period,but 11 patients had mild adverse re-actions.Conclusion The 8-week treatment regimen of glecaprevir/pibrentasvir for non-cirrhotic patients with geno-type 1,3,and 6 HCV/HIV co-infection can achieve 100％SVR12,with high safety and tolerability,which can be used as a good choice for clinical treatment of these patients.

Objective To investigate the effect of acupuncture on fatigue improvement and gut microbiota in mice with cancer-related fatigue(CRF),and explore its possible mechanism of action.Methods The mice model of CRF of breast cancer after chemotherapy was established by tumor bearing and chemotherapy.After acupuncture intervention,fatigue was evaluated by general condition,forced swimming and open field experiment.Then 16S rDNA sequencing was used to analyze the structural abundance of gut microbiota in mice.Results Acupuncture could significantly improve the fatigue degree and general condition of the mice model of CRF of breast cancer after chemotherapy.At the same time,acupuncture could adjust the abundance of gut microbiota structure,up-regulate the abundance levels of Lactobacillus,Bacteroides,firmicutes,actinobacteria,and down-regulate the abundance levels of Proteobacteria and Staphylococcus.There were also differences in the abundance of flora structure among the groups,but the abundance of beneficial bacteria was relatively high in the acupuncture group,and the abundance of pathogenic bacteria was relatively high in the other two groups.Conclusion Acupuncture may play a role in the treatment of CRF by regulating the abundance of gut microbiota structure,increasing intestinal beneficial bacteria,inhibiting pathogenic bacteria,improving body immunity,and alleviating adverse reactions caused by chemotherapy for breast cancer.

Objective:To compare the differences in the prevalence of mild micro-hepatic encephalopathy (MHE) among patients with cirrhosis by using the psychometric hepatic encephalopathy score (PHES) and the Stroop smartphone application (Encephal App) test.Methods:This prospective, multi-center, real-world study was initiated by the National Clinical Medical Research Center for Infectious Diseases and the Portal Hypertension Alliance and registered with International ClinicalTrials.gov (NCT05140837). 354 cases of cirrhosis were enrolled in 19 hospitals across the country. PHES (including digital connection tests A and B, digital symbol tests, trajectory drawing tests, and serial management tests) and the Stroop test were conducted in all of them. PHES was differentiated using standard diagnostic criteria established by the two studies in China and South Korea. The Stroop test was evaluated based on the criteria of the research and development team. The impact of different diagnostic standards or methods on the incidence of MHE in patients with cirrhosis was analyzed. Data between groups were differentiated using the t-test, Mann-Whitney U test, and χ2 test. A kappa test was used to compare the consistency between groups. Results:After PHES, the prevalence of MHE among 354 cases of cirrhosis was 78.53% and 15.25%, respectively, based on Chinese research standards and Korean research normal value standards. However, the prevalence of MHE was 56.78% based on the Stroop test, and the differences in pairwise comparisons among the three groups were statistically significant (kappa = -0.064, P < 0.001). Stratified analysis revealed that the MHE prevalence in three groups of patients with Child-Pugh classes A, B, and C was 74.14%, 83.33%, and 88.24%, respectively, according to the normal value standards of Chinese researchers, while the MHE prevalence rates in three groups of patients with Child-Pugh classes A, B, and C were 8.29%, 23.53%, and 38.24%, respectively, according to the normal value standards of Korean researchers. Furthermore, the prevalence rates of MHE in the three groups of patients with Child-Pugh grades A, B, and C were 52.68%, 58.82%, and 73.53%, respectively, according to the Stroop test standard. However, among the results of each diagnostic standard, the prevalence of MHE showed an increasing trend with an increasing Child-Pugh grade. Further comparison demonstrated that the scores obtained by the number connection test A and the number symbol test were consistent according to the normal value standards of the two studies in China and South Korea ( Z = -0.982, -1.702; P = 0.326, 0.089), while the other three sub-tests had significant differences ( P < 0.001). Conclusion:The prevalence rate of MHE in the cirrhotic population is high, but the prevalence of MHE obtained by using different diagnostic criteria or methods varies greatly. Therefore, in line with the current changes in demographics and disease spectrum, it is necessary to enroll a larger sample size of a healthy population as a control. Moreover, the establishment of more reliable diagnostic scoring criteria will serve as a basis for obtaining accurate MHE incidence and formulating diagnosis and treatment strategies in cirrhotic populations.
