Objective To summarize and analyze the efficacy and influencing factors of second allogeneic hematopoietic stem cell transplantation (allo-HSCT) for acute leukemia relapsing after the first allo-HSCT. Methods Clinical data of 17 patients with acute leukemia who underwent second allo-HSCT at Peking University First Hospital from January 2005 to December 2024 were retrospectively analyzed. Results Among the 17 patients, 7 achieved long-term disease-free survival after second transplantation. The median progression-free survival after successful second transplantation was 7 months (range 8 days to 69 months). The relapse fatality was 24%, and the transplant-related fatality was 35%. Conclusions Second transplantation is an effective treatment for relapsed and refractory acute leukemia, but the relapse fatality and transplant-related fatality remain high. Patient age, time of relapse after the first transplantation and disease status before second transplantation are all factors that affect the efficacy of second transplantation. Younger age, late relapse and complete remission of disease before second transplantation are all beneficial for long-term disease-free survival after second transplantation.

Diabetic cognitive impairment （DCI） has an insidious onset and progressive and irreversible development. There is currently no first-line treatment for DCI. Early intervention of diabetes with traditional Chinese medicine （TCM） can effectively control blood sugar and improve cognitive impairment， which has significant advantages. As a representative of bitter and cold heat-clearing medicines， Coptidis Rhizoma， known for its abilities to clear heat and dampness and remove turbidity and toxins， has been widely used in the clinical prevention and treatment of diabetes， Alzheimer's disease， vascular dementia， and other cognitive impairments. This article systematically summarized relevant literature and observed that Coptidis Rhizoma has shown good potential in the prevention and treatment of DCI with its active ingredients such as berberine and quercetin， drug pairs such as Coptidis Rhizoma-Scutellariae Radix， Coptidis Rhizoma-Acorus Tatarinowii Rhizoma， Coptidis Rhizoma-Pinelliae Rhizoma， Coptidis Rhizoma-Zingiberis Rhizoma， and prescriptions such as Gegen Qinliantang， Huanglian Jiedutang， Banxia Xiexintang， Huanglian Wendantang， Jiaotai Wan， Danggui liuhuangtang， and related Chinese patent medicines. Its mechanism may be related to regulating glucose metabolism， improving insulin resistance， improving amyloid β-protein （Aβ） deposition and tau protein phosphorylation， inhibiting neuroinflammation and oxidative stress， and regulating the "microbe-gut-brain axis". The article systematically reviewed the research progress of Coptidis Rhizoma and its prescriptions in the prevention and treatment of DCI， aiming to preliminarily explain the scientific connotation of Coptidis Rhizoma and provide a basis for its clinical application in the prevention and treatment of DCI.

Objective:To evaluate the efficacy and safety of brentuximab vedotin (BV) combined with rituximab and attenuated chemotherapy in the treatment of children with classic Hodgkin lymphoma (cHL).Methods:A prospective, non-randomized, risk-assigned study. Clinical data (including age, gender, B symptoms, bulky disease, CD30 and Epstein-Barr virus-encoded RNA(EBER) expression, clinical stage, risk stratification, etc.) of 28 intermediate to high-risk cHL children diagnosed and treated at Beijing Children′s Hospital Affiliated to Capital Medical University from October 2022 to May 2024 were collected. Immuno-targeted combined with attenuated chemotherapy was administered based on risk stratification and early treatment response. The patients were followed up until May 1st, 2024. The infusion reactions and adverse reactions after treatment were recorded.Results:In all 28 patients, there were 22 males and 6 females, the age was 12 (5,16) years, 16 cases (57%) presented with bulky disease and 10 cases (36%) with B symptoms. The most common pathological type was nodular sclerosis (14 cases, 50%). There were 7 cases of stage Ⅱ, 14 cases of stage Ⅲ and 7 cases of stage Ⅳ according to the Ann Arbor staging system. There were 5 cases in the intermediate-risk group and 23 cases in the high-risk group. EBER was positive in 20 cases (71%) and negative in 6 cases (21%), and CD30 antigen was expressed in tumor cells of all enrolled children. Treatment duration: 5 cases (18%) received 4 courses of treatment, 21 cases (75%) received 6 courses of treatment, and 2 cases (7%) received 8 courses of treatment, 25 cases (89%) achieved complete metabolism response (CMR) through early assessment after 2 courses of chemotherapy. The CMR rates were 100% in intermediate-risk group and 87% (20/23) in high-risk group, respectively. Four patients (14%) finally received residual field radiotherapy. Toxicities included grade Ⅰ-Ⅱ myelosuppression, early infusion reaction and mild peripheral neuropathy, only one case of grade 3 adverse events was recorded and did not affect sequential treatment. At the end of treatment and 3 months of follow-up, the levels of IgA, IgG and IgM were all decreased compared with the baseline before chemotherapy, and the total B cell count began to be lower than the level before chemotherapy at the early stage of treatment (after 2 courses). The total B cell count monitored during treatment was 50 (0, 101)×10 6/L and was 12 (0, 25)×10 6/L at the end of treatment. The follow-up time was 6 (3, 13) months, all 28 children had event-free survival and all achieved complete remission. At 6 and 9 months of follow-up, IgA, IgG, IgM and total B cell counts returned to pre-chemotherapy baseline levels, respectively. Conclusion:BV combined with rituximab attenuated chemotherapy has demonstrated efficacy and a tolerable safety profile in the treatment of cHL in children, and significantly reduce radiation rate.

Objective:To investigate the status quo of educational and teaching research in community bases for general practice standardized residency training in China.Methods:The studies related to education research in community bases for general practice standardized residency training were searched from Chinese Journal Full Text Database (CNKI), Wanfang Database and China Science and Technology Journal Database (VIP) from inception to November 30, 2023. The keywords of "standardized training of general practitioner residents" or "general practice standardized training" or "general practitioner standardized training" or "general practice training" and "community-based teaching " or "community training" "community base" or "community teaching" were used for search, and affiliations of authors should contain"community health service center". The literature was read and summarized using Endnote and Excel software.Results:A total of 171 articles were retrieved that met the criteria, and 130 articles were finally selected for analysis according to the quality review criteria of the literature. The authors of articles were distributed in 78 institutions of 17 provinces or regions, with 9 provinces or regions having a total of 123 articles (94.6%) with 2 published articles or more, of which the highest number was found in Beijing and Shanghai. Seventeen institutions published 2 or more articles with a total of 69 articles (53.1%), including 67 articles (51.5%) were co-authored by 2 units. The ranking top ten institutions in terms of the number of articles published were 5 community health service centers in Beijing, 4 in Shanghai (co-authored with Shanghai Zhongshan Hospital). There were 46 articles (35.4%) published in core journals and 55 articles (42.3%) with fund-supported projects. The studies presented teaching methods, teaching and training contents, teaching evaluation and effects, teacher training, teaching base construction and information technology application.Conclusion:The educational and teaching research in community bases for general practice standardized training in China has gradually received attention, the researches were mainly carried out by community medical institutions, but the overall quality of research needs to be further improved.

Objective:To investigate the factors that influence the prolongation of gestation following emergency cervical cerclage.Methods:This retrospective study included 88 singleton pregnant women who were diagnosed with cervical incompetence and underwent emergency cervical cerclage at 12-26 weeks of gestation in the Jiaxing Maternity and Child Health Care Hospital from January 1, 2019 to September 1, 2022. The participants who delivered after 28 gestational weeks were assigned to the success group ( n=77), while those who delivered or miscarried before 28 gestational weeks were assigned to the failure group ( n=11). Two independent sample t-test or Mann-Whitney U test was used for comparison between groups. The factors affecting the prolongation of gestation after the procedure were selected by univariate analysis and multiple regression equations. Results:The success rate (delivery rate≥28 weeks) was 87.5% (77/88). There were six women delivered at 28-31 +6 weeks of gestation (6/77, 7.8%), two at 32-33 +6 weeks of gestation (2/77, 2.6%), 16 at 34-36 +6 weeks of gestation (16/77, 20.8%), and 53 at 37 weeks of gestation or later (53/77, 68.8%). Multiple regression analysis indicated that three times of early pregnancy miscarriage ( β=－5.1, 95% CI: -9.5 to -0.7), five times of early pregnancy miscarriage ( β=－11.8, 95% CI: -22.1 to -1.6), had two live births ( β=－6.9, 95% CI: -12.9 to -0.9), gestational age at cerclage ( β=－0.6, 95% CI: -1.0 to -0.3), external cervical os dilation<15 mm ( β=－12.1, 95% CI: -22.5 to -1.8) and ≥15 mm before cerclage ( β=－11.0, 95% CI: -21.4 to -0.71) were factors affecting the prolongation of gestation after cerclage. After adjusting for maternal age and weight before emergency cervical cerclage, five times of early pregnancy miscarriage ( β=－18.1, 95% CI: -28.3 to -7.8), gestational age at cerclage ( β=－0.6, 95% CI: -1.0 to -0.3), and external cervical os dilation≥15 mm before cerclage ( β=－11.4, 95% CI:－21.2 to -1.6) remained the significant influencing factors (all P<0.05). Conclusion:The number of early pregnancy miscarriages, gestational age at cerclage, and the width of external cervical os dilation before cerclage≥15 mm are the factors that influence the prolongation of gestation after the emergency cervical cerclage procedure.

Regulatory T cell (Tregs) predominantly maintain the immune balance and prevent autoimmunity via their immunosuppressive functions. However, tumor-infiltrating Tregs (TI-Tregs) may mediate tumor immune tolerance in complex tumor microenvironments, resulting in poor prognosis. Distinguishing specific TI-Treg subpopulations from peripheral Tregs and intratumoral conventional T cells (Tconvs) has recently emerged as an important topic in antitumor therapy. In this review, we summarize novel therapeutic approaches targeting both the metabolic pathways and hallmarks of TI-Tregs in preclinical and clinical studies. Although the phenotypic and functional diversity of TI-Tregs remains unclear, our review provides new insights into TI-Treg-based therapies and facilitates precision medicine for tumor treatment.

Objective:To explore the effects of hospital-to-community model-based case management on outcomes and life quality of patients with atrial fibrillation.Methods:By convience sampling method, a total of 90 cases of atrial fibrillation patients admitted to Changzhou Second People′s Hospital from January 2019 to May 2020 were randomly divided into control group and experimental group, with 45 cases in each group. The patients in the control group received routine nursing care, the experimental group implemented hospital-to-community model-based case management. The beliefs about medicine, medication compliance, quality of life and readmissions of cardiovascular events were compared between 2 groups before and 6 months after intervention.Results:Finally, 41 cases were included in the experimental group and 38 cases in the control group. Before intervention, there were no significant differences in various indexes between the two groups ( P>0.05). After 6 months of intervention, the scores of specific-necessity in Beliefs about Medicines Questionnaire-Specific (BMQ-Specific) and Morisky Medication Adherence Scale-8 (MMAS-8) were (16.98 ± 4.22) and (7.15 ± 0.69) points in the experimental group, higher than in the control group (14.95 ± 4.33) and (6.32 ± 1.07) points; the scores of specific-concerns in BMQ-Specific were (6.83 ± 1.91)points in the experimental group, lower than in the control group (8.42 ± 2.73) points. The differences were statistically significant ( t = 2.11, 4.07, 2.98, all P<0.05); the scores of physical function, role-physical, pain, general health, mental health dimensions and total scores in SF-36 were (80.37 ± 3.46), (46.63 ± 14.54), (90.37 ± 5.78), (70.07 ± 9.98), (84.20 ± 8.73) and (584.88 ± 25.71) points in the experimental group, higher than in the control group (70.13 ± 11.20), (37.34 ± 10.25), (83.37 ± 6.89), (59.55 ± 7.98), (77.58 ± 9.09) and (533.87 ± 31.62) points, the differences were statistically significant ( t values were 3.30-7.89, all P<0.05). At 6 months after discharge, the re-admission of cardiovascular events were 5 cases (12.2%) in the experimental group and 12 cases (31.6%) in the control group, the difference was statistically significant ( χ2=4.74, P<0.05). Conclusions:Hospital-to-community model-based case management can effectively promote beliefs about medicine and medication compliance, improve quality of life and decrease re-admission of cardiovascular events of patients with atrial fibrillation.

Objective:To explore the optimum time of ambulation of atrial fibrillation patients after radiofrequency ablation, to provide basis for patients' early postoperative rehabilitation.Methods:By convenient sampling method, a total of 120 patients with atrial fibrillation after radiofrequency ablation were collected at Yanghu Branch and City Branch of Changzhou Second People's Hospital from January 2020 to May 2021. They were divided into the early group, middle group and late group according to the random number table method, each group were 40 cases. All patients received routine postoperative intervention, the time of ambulation were 4, 6 and 12 h after operation in the early group, middle group and late group, respectively. The complication rate within 24 h after operation was compared among the three groups, and the comfort level of the three groups at 24, 48 and 72 h after operation was evaluated with Comfort Status Scale (GCQ).Results:Finally, 111 patients were included, including 37 in the early group, 38 in the middle group and 36 in the late group. There was no significant difference in the incidence of bleeding or hematoma, urinary retention, lumbago within 24 h after operation among the three groups ( P>0.05). The incidence of postural hypotension within 24 h after operation in the early group was 2.7% (1/37), which was lower than 21.1% (7/38) and 25.0% (9/36) in the middle and late groups, with a statistically significant difference ( χ2=4.86, 7.67, both P<0.05). At 48 and 72 h after operation, the scores of physiological dimension, psychological dimension and the total score of GCQ in the early group were (20.68 ± 3.07), (22.54 ± 3.35), (81.68 ± 6.11) and (22.54 ± 3.73), (24.38 ± 2.49), (84.92 ± 6.37), higher than those in the middle group (19.16 ± 2.19), (21.32 ± 2.27), (78.24 ± 5.58), (20.93 ± 2.85), (22.32 ± 2.04), (81.66 ± 6.56), and those in the late group (18.44 ± 1.50) (21.31 ± 1.99), (78.06 ± 4.32), (20.89 ± 2.25), (21.58 ± 1.86), (80.28 ± 6.44), the differences were statistically significant ( t values were 2.19-4.15, all P<0.05). Conclusions:Ambulation at 4 h after operation does not increase peripheral vascular complications, but can reduce the incidence of postural hypotension and improve the comfort of patients with atrial fibrillation after radiofrequency ablation.
