Objective To investigate the therapeutic effects and mechanisms of Jianyang Tablets(mainly with the functions of tonifying the kidneys,replenishing essence,invigorating yang,and alleviating erectile dysfunction)on erectile dysfunction(ED)in rats with liver depression and kidney deficiency syndrome.Methods The 60 male SD rats were randomly divided into a normal group,a model group,a Tadalafil group,and low-,medium-,and high-dose Jianyang Tablets groups.Except for the normal group,all other groups underwent a 14-day composite modeling protocol combining intramuscular hydrocortisone injections and limb immobilization to induce ED with liver depression and kidney deficiency syndrome.Treatments were administered for 28 consecutive days after successful modeling.The body mass differences were recorded and compared before and after the experiment.Behavioral assessments included open-field test and mounting test were conducted.Enzyme-linked immunosorbent assay(ELISA)was used to measure nitric oxide synthase(NOS),cyclic adenosine monophosphate(cAMP),and cyclic guanosine monophosphate(cGMP)levels in penile cavernous tissues.Nitric oxide(NO)level was quantified using the Griess reagent colorimetric method.Results Compared with the normal group,the model group exhibited reduced horizontal activity grid counts in the open-field test,prolonged mounting latency,decreased mounting frequency,decreased body mass,and reduced levels of NOS,NO,cGMP,and cAMP in penile cavernous tissues,with statistical significance(P＜0.05 or P＜0.01).Compared with the model group,the Tadalafil group and medium-and high-dose Jianyang Tablets groups showed increased horizontal activity grid counts and vertical activity counts in the open-field test,shortened mounting latency,elevated mounting frequency,increased body mass,and upregulated levels of NOS,NO,cGMP,and cAMP in penile cavernous tissues,with statistical significance(P＜0.05 or P＜0.01).No significant differences were observed among the intervention groups for the aforementioned indices(P＞0.05).Conclusion Jianyang Tablets effectively improves erectile function in rats with liver depression and kidney deficiency syndrome,potentially mediated by modulation of the NO-cGMP signaling pathway.

Neuroimmunological diseases are immune-mediated neurological disorders, such as neuromyelitis optica spectrum disorders, multiple sclerosis, and myasthenia gravis. With several monoclonal antibodies that target B cells approved and marketed, the treatment of neuroimmune diseases experienced rapid advances. Despite these successes, challenges remain, particularly for patients who do not respond to conventional therapies, underscoring the need for innovative approaches. Since initial success in the treatment of B cell-derived malignancies, chimeric antigen receptor T (CAR-T) cell therapy as a novel cellular therapy has shown dramatic therapeutic potential in neuroimmunological diseases recently. In this review, the therapeutic evidence, research progress and the challenges of CAR-T cell therapies targeting B cells in neuroimmunological diseases are summarized, providing a novel perspective for the treatment of neuroimmunological diseases.

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.

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 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.
