ObjectiveTo investigate the effect of community-based rehabilitation exercise and physical activity on the physical activity levels, functional states, and quality of life for people with mild and moderate disabilities in community settings, to ascertain the health benefits of their engagement in such fitness sports activities, anchoring in the WHO "Global Action Plan on Physical Activity 2018-2030: More Active People for a Healthier World" and the guidelines tailored for people with disabilities, using the theoretical framework and methodology of the International Classification of Functioning, Disability and Health (ICF). MethodsAligning with the WHO guidelines for people with disabilities and the ICF, a community-based rehabilitation exercise and physical activity program was designed for individuals with mild to moderate disabilities, featuring activities like fitness training (aerobic and resistance exercises), skill exercises (such as balance and coordination), as well as sports and recreational games (ball and games, etc.). A total of 230 people with mild and moderate disabilities were recruited from 20 communities in Shenzhen, with types of disabilities including physical, speech, intellectual, and mental. Professional rehabilitation fitness instructors implemented and supervised the program. The activities were of low to moderate intensity, 30 to 50 minutes per session, five times a month for six months. The community-based rehabilitation exercise and physical activity progress of these individuals was surveyed using the International Physical Activity Questionnaire (IPAQ), and their overall functioning was evaluated with WHODAS 2.0. The health-related quality of life was measured with WHOQOL-BREF. The health benefits from participation in community-based rehabilitation exercise and physical activity were assessed in terms of functioning, activity involvement, and quality of life. ResultsAfter the fitness activities, participation levels significantly increased in IPAQ domains of work-related, transport-related, domestic and gardening activity, and leisure time (|t| > 3.391, P < 0.001). The scores significantly decreased in the domains of cognition, activity, self-care, getting along, life activities and participation; and overall scores also decreased in WHODAS 2.0 (t > 6.639, P < 0.001). The scores significantly increased in the four dimensions of WHOQOL-BREF (|t| > 7.486, P < 0.001). ConclusionAfter participating in a six-month community-based rehabilitation exercise and physical activity program of mild to moderate intensity, individuals with mild to moderate disabilities have improved in physical activity and engagement levels, and the overall functioning and quality of life.

Objective:To investigate the incidence and risk factors of deep vein thrombosis(DVT)in patients with rheumatoid arthritis(RA).Methods:The clinical data of RA patients who were hospi-talized in the Department of Rheumatology and Immunology of Aerospace Center Hospital from May 2015 to September 2021 was retrospectively analyzed,including demographic characteristics,concomitant diseases,laboratory examinations(blood routine,biochemistry,coagulation,inflammatory markers,rheumatoid factor,antiphospholipid antibodies and lupus anticoagulant,etc.)and treatment regimens.The patients were compared according to the presence or absence of DVT,and the t test,Mann-Whitney U test or Chi-square test were applied to screen for relevant factors for DVT,followed by Logistic regres-sion analysis to determine risk factors for DVT in patients with RA.Results:The incidence of DVT in the RA patients was 9.6％(31/322);the median age of RA in DVT group was significantly older than that in non-DVT group[64(54,71)years vs.50(25,75)years,P＜0.001];the level of disease activity score using 28 joints(DAS28)-erythrocyte sedimentation rate(ESR)in DVT group was higher than that in non-DVT group[5.2(4.5,6.7)vs.4.5(4.5,5.0),P＜0.001];the incidence of hypertension,chronic kidney disease,fracture or surgery history within 3 months,and varicose veins of the lower ex-tremities in DVT group was higher than that in non-DVT group(P＜0.001).The levels of hemoglobin and albumin in DVT group were significantly lower than that in non-DVT group(P=0.009,P=0.004),while the D-dimer level and rheumatoid factor positive rate in DVT group were significantly higher than that in non-DVT group(P＜0.001).The use rate of glucocorticoid in DVT group was higher than that in non-DVT group(P=0.009).Logistic regression analysis showed that the age(OR=1.093,P＜0.001),chronic kidney disease(OR=7.955,P=0.005),fracture or surgery history with-in 3 months(OR=34.658,P=0.002),DAS28-ESR(OR=1.475,P=0.009),and the use of glu-cocorticoid(OR=5.916,P=0.003)were independent risk factors for DVT in RA patients.Conclu-sion:The incidence of DVT in hospitalized RA patients was significantly increased,in addition to tradi-tional factors,such as age and chronic kidney disease,increased DAS28-ESR level and the use of glu-cocorticoid were also independent risk factors for DVT.

Objective To analyze the needs and current situation of home-based exercise rehabilitation for people with disabilities,develop service plans for different types of disabilities,and assess its health benefits for people with severe dis-abilities. Methods Based on the World Health Organization(WHO)Global Action Plan on Physical Activity 2018-2030:More Ac-tive People for a Healthier World and WHO Guidelines on Physical Activity and Sedentary Behavior,functional and individualized home-based exercise rehabilitation plans for people with severe disabilities were developed.Begining from May,2023,a six-month intervention was conducted for 37 people with severe disabilities.They were assessed with International Physical Activity Questionnaire(IPAQ),WHO Disability Assessment Schedule 2.0(WHODAS 2.0),WHO Quality of Life(WHOQOL-BREF)before and after intervention. Results The time of low-intensity leisure physical activity of IPAQ increased after intervention,while the scores of do-mains of cognition,mobility,self-care,getting along,life activities and participation,and total score of WHO-DAS 2.0 decreased,and the scores of physical health,psychological health,independence,and environment di-mensions,and total score of WHOQOL-BREF increased. Conclusion The functioning-oriented and individualized home exercise rehabilitation program can improve the level of physical activity,enhance the level of activity and boost the quality of life for people with severe disabilities.

Objective To investigate the mechanism underlying gasdermin E(GSDME)-mediated pyroptosis in radiation-induced intestinal injury and to find out whether gasdermin(GSDM)family members regulate pyroptosis through similar signaling pathways.Methods Human normal colon epithelial cells(NCM460)and human colon cancer cells(HT-29)were exposed to radiation of different doses and durations before pyroptosis indicators were evaluated by observing pyroptotic bubbles,cell survival,and the cleavage of pyroptosis execution proteins.HT-29 cells overexpressing GSDME were subjected to radiation,followed by enrichment analysis of pyroptosis-related differentially expressed genes using RNA-seq.Results Radiation induced substantial pyroptosis in NCM460 cells.Overexpression of GSDME in HT-29 cells resulted in substantial radiation-induced pyroptosis.The pyroptosis state of human intestinal cells was simulated in the HT-29 model cell line.Overexpressions of GSDME-N and GSDMD-N resulted in the expression of more than 50％ of the differentially expressed genes in the pyroptosis state.Sequencing analysis showed that the genes in the pyroptosis state were mainly overrepresented in immune response,inflammatory response,and Rapl signaling pathway.Conclusion GSDME activation can mediate radiation-induced pyroptosis by producing GSDME-N fragments.GSDM family members participate in pyroptosis in a similar mode of regulation.Furthermore,radiation-induced activation of GSDME/D may regulate pyroptosis through immune response,inflammatory response,and Rap1 signaling pathway.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

The study aimed to analyze the efficacy and safety of rituximab in the treatment of 23 cases of lupus nephritis and explore the prospect of half-dose rituximab in lupus nephritis treatment. Twenty-three patients with lupus nephritis hospitalized in the Department of Rheumatology and Immunology at the First Medical Center of the PLA General Hospital from May 2013 to December 2021 were selected. Eighteen patients received rituximab 375 mg/m 2 on the first and 14th days, 5 patients received 500 mg of rituximab on the first and 14th days, and rituximab was used as needed 6 months later. Methylprednisolone (80-120 mg) was given together with rituximab. Afterward, 1 mg/kg prednisone was used for 4 weeks, which was progressively tapered to maintenance doses or discontinued. B lymphocyte level, renal function, 24-h urine protein level, and systemic lupus erythematosus (SLE) disease activity index 2000 (SLEDAI2K) score before and after treatment were recorded. The efficacy and adverse reactions were analyzed. The results showed that 11 patients suffered from renal insufficiency [creatinine (162.7±58.6) μmol/L ] at baseline, while the creatinine level of 9 patients returned to normal 12 months after the treatment [ (66.3±10.1)μmol/L ]. Normal renal function of the other 12 patients was maintained during treatment. After 12 months, the 24-h urine protein level decreased from 4.00 (2.00,6.80) g in the baseline period to 0.10 (0.08,0.40) g. SLEDAI2K score decreased from 22 (18,26) in the baseline period to 3 (0,6) 12 months after the treatment. The B lymphocyte level reached 0.00 (0.00,0.01)% at 3 months. Of 23 patients, 13 patients achieved complete remission, and 7 patients achieved partial remission after 6 months of rituximab treatment. Five patients experienced adverse reactions related to rituximab, including 1 case of transfusion reaction, 1 case of perioral herpes with pulmonary infection, and 3 cases of decreased IgG levels. Therefore, rituximab regimen used in this study can be an effective treatment strategy for lupus nephritis.

This consensus aims to provide a reference for colleagues responsible for postoperative follow-up of esophageal squamous cell carcinoma patients in China, and further improve the standardization of the diagnosis and treatment of esophageal squamous cell carcinoma.

Objective    To explore whether surgery combined with adjuvant chemotherapy can bring survival benefits to patients with cervical and upper thoracic esophageal squamous cell carcinoma (ESCC). Methods    The clinical data of patients with cervical and upper thoracic ESCC who underwent R0 resection and neck anastomosis in our department from 2006 to 2010 were retrospectively analyzed. Patients received neoadjuvant therapy or adjuvant radiotherapy were excluded. The adjuvant chemotherapy group was given a combination of taxanes and platinum based chemotherapy after surgery; the surgery alone group did not receive adjuvant chemotherapy. The Kaplan-Meier method was used to analyze the survival difference between the adjuvant chemotherapy group and the surgery alone group. Results    A total of 181 patients were enrolled, including 141 (77.9%) males and 40 (22.1%) females, with an average age of 61.0±8.2 years (80 patients aged≤61 years, 101 patients aged>61 years). There were 70 (38.7%) patients of cervical ESCC, and 111 (61.3%) patients of upper thoracic ESCC. Eighty-seven (48.1%) patients underwent postoperative adjuvant chemotherapy, and 94 (51.9%) patients underwent surgery alone, and the basic clinical characteristics were well balanced between the two groups (P>0.05). The median survival time of patients in the adjuvant chemotherapy group and the surgery alone group was 31.93 months and 26.07 months, and the 5-year survival rate was 35.0% and 32.0%, respectively (P=0.227). There was no statistical difference in median survival time between the cervical ESCC and upper thoracic ESCC group (31.83 months vs. 29.76 months, P=0.763). For cervical ESCC patients, the median survival time was 45.07 months in the adjuvant chemotherapy group and 14.70 months in the surgery alone group (P=0.074). Further analysis showed that the median survival time of lymph node negative group was 32.53 months, and the lymph node positive group was 24.57 months (P=0.356). The median survival time was 30.43 months in the lymph-node positive group with adjuvant chemotherapy and 17.77 months in the lymph-node positive group with surgery alone. The survival curve showed a trend of difference, but the difference was not statistically significant (P=0.557). Conclusion    There is no statistical difference in the long-term survival of cervical and upper thoracic ESCC patients after R0 resection. Postoperative adjuvant chemotherapy may have survival benefits for patients with cervical ESCC and upper ESCC with postoperative positive lymph nodes, but the differences are not statistically significant in this setting.

Objective:To analyze the characteristics of pulse-step-sine (PSS) test in healthy people of different ages and to discuss its clinical value.Methods:From July 10, 2018 to December 9, 2020, a total of 78 healthy volunteers, including 40 males and 38 females, were enrolled and divided into youth group, middle age group and old age group. The I Portal NOTC rotational-chair system (NKI) was applied for PSS detection to analyze the clinical characteristics of gain, phase, asymmetry, and slope of step and sinusoidal components. Statistical analysis was performed using SPSS17.0 software.Results:In the same age group, there were no statistically significant differences in left and right step gain, slope gain and sine gain (All P values were greater than 0.05). Pairwise comparison between different age groups showed that there was no significant difference in the corresponding parameters between the youth group and the middle age group. Compared with young group, the old age group had a significantly lower step gain value in their left side ( P<0.01) but not in the right side ( P>0.05).The left and right slopes of the old age group were significantly lower than those of the young group and the middle group, and the differences were statistically significant (All P values<0.05). Conclusion:The PSS test can detect bilateral and unilateral horizontal semicircular canal function with good tolerance in different age groups, better than the traditional rotational chair examination to determine the well-compensated unilateral vestibular function. PSS test is a new vestibular detection method.

Objective    To compare the 5-year survival rates between two different follow-up patterns of postoperative stage Ⅰ-ⅢA non-small cell lung cancer (NSCLC) patients. Methods    Pathological stage Ⅰ-ⅢA NSCLC 11 958 patients who underwent surgical resection and received follow-up within 6 months after initial diagnosis through telephone follow-up system were included in nine hospitals from July 2014 to July 2020. The patients were divided into two groups including a proactive follow-up group (n=3 825) and a passive follow-up group (n=8 133) according to the way of following-up. There were 6 939 males and 5 019 females aged 59.8±9.5 years. The Kaplan-Meier and Cox proportional hazards regression model were used. Results    The median follow-up frequency was 8.0 times in the proactive follow-up group and 7.0 times in the passive follow-up group. The median call duration was 3.77 minutes in the proactive follow-up group and 3.58 minutes in the passive follow-up group. The 5-year survival rate was 81.8% and 74.2% (HR=0.60, 95CI 0.53-0.67, P<0.001) in the proactive follow-up group and the passive follow-up group, respectively. Multivariate analysis showed that follow-up pattern, age, gender and operation mode were independent prognostic factors, and the results were consistent in all subgroups stratified by clinical stages. Conclusion    The proactive follow-up leads to better overall survival for resected stage Ⅰ-ⅢA NSCLC patients, especially in the stage ⅢA.
