Objective Explore the impact of long-term blood glucose fluctuations and blood glucose control on the stroke incidence in patients with type 2 diabetes mellitus(T2DM).Methods An observa-tional cohort of patients with T2DM was established based on"Shanghai Community Chronic Disease Health Management Service Objects"on October 1st,2018.Follow-ups were conducted every three months,and fasting blood glucose(FBG)were tested at each visit.Basic epidemiological data were collected via the Shanghai Community Health Management Information Platform or survey questionnaires,and stroke incidents were gathered via the"Shanghai Cardio-Cerebrovascular Event Monitoring System".The first reported stroke incident within the observation period was considered.The observational deadline was December 31st,2021.Standard deviation of FBG was used to evaluate blood glucose fluctuation and FBG control rate was used to reflect blood glucose control status.Cox Proportional Hazards Model was utilized to analyze the impacts.Results The cumulative observation time was 91,826.1 person-years for the study,in which there were 1785 cases of stroke events observed,implying a cumulative incidence of 5.73%and incidence rate of 1943.9/100000 person-years.The mean number of follow-ups(10.29±3.07)per patient was recorded.The details of the stroke cases were as follows:transient ischemic attacks(n=111,6.22%),non-lacunar brain infarctions(n=754,42.24%),lacunar brain infarctions(n=798,44.71%),intracerebral hemorrhages(n=80,4.48%),non-intracerebral hemorrhages(n=8,0.45%),subarachnoid hemorrhages(n=12,0.67%),and unclassified strokes(n=22,1.23%).After excluding subjects with less than five follow-ups,the Cox Proportional Hazards Model suggested that increased standard deviation of FBG was an independent risk factor for the first stroke incident,and an increased blood glucose control rate was an independent protective factor.Both the standard deviation of FBG and the blood glucose control rate were not correlated with stroke recurrence.Conclusion Long-term blood glucose fluctuations and blood glucose control can predict the risk of a first stroke in patients with T2DM.The relationship between blood glucose fluctuations,blood glucose management,and stroke recurrence requires further studies.

Objective To evaluate the effectiveness of moderate-intensity aerobic exercise in patients with chronic schizophrenia,focusing on its effects on neuroplasticity markers such as serum brain-derived growth factor(BDNF)and insulin-like growth factor-1(IGF-1),and analyze the relationship between therapeutic efficacy and neuroplasticity indicators.Methods A total of 200 schizophrenic patients treated at the Affiliated Kangning Hospital of Wenzhou Medical University from January 2021 to December 2023 were selected and randomly divided into study group and control group,100 patients in each group based on a random number table.The positive and negative syndrome scale(PANSS)was used to assess the patients'psychiatric symptoms before and after treatment.The repeatable battery for the assessment of neuropsychological status(RBANS)was employed to evaluate the patients'cognitive function,while the social functioning in psychosis patient inventory(SSFPI)was used to assess their social function.Additionally,the levels of BDNF and IGF-1 in the patients'peripheral blood were measured.Differences in relevant indicators before and after treatment were compared,and influencing factors were analyzed.Results ①Compared with control group,patients in study group exhibited significant improvements in cognitive function(RBANS total score,immediate memory score,visual span score),social function(SSFPI total score,daily living ability score,kineses and social interaction score,social activity skill score),and neuroplasticity indicators(BDNF and IGF-1 differences)(P<0.05);②After treatment,the IGF-1 difference in patients'serum was positively correlated with the improvement in visual span within cognitive function.Furthermore,the differences in BDNF and IGF-1 were also positively correlated with improvements in multiple indicators of social function,including SSFPI total score,daily living ability,kineses and social interaction,and social activity skills(P<0.05);③Stepwise regression analysis revealed that the differences in BDNF and IGF-1 could predict the degree of improvement in SSFPI total score and various factor scores,accounting for 37.90%to 41.70%of the variation.Conclusion Moderate intensity aerobic exercise can improve cognitive function in patients with chronic schizophrenia,mainly including immediate memory,visual breadth,and social function.The specific mechanism may be related to the elevated levels of BDNF and IGF-1 in patients.

Objective:To investigate the application value of transanal endoscopic partial intersphincteric resection for ultra-low rectal cancer.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 9 ultra-low rectal cancer patients undergoing transanal endoscopic partial intersphincteric resection at the First Affiliated Hospital of Xiamen University from December 2017 to August 2020 were collected. There were 8 males and 1 female, aged from 39 to 62 years, with a median age of 58 years. Observation indicators: (1) surgical and postoperative situations; (2) postoperative pathological examination; (3) follow-up. Follow-up was conducted using outpatient examination and telephone interview to detect postoperative tumor local recurrence and distant metastasis, survival of patients, ileostomy closure, anus function at 3 months after ileostomy closure, male urinary and sexual function and female sexual function at 6 months after rectal surgery. The follow-up was up to February 2021. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results:(1)Surgical and postoperative situations: all 9 patients underwent surgery successfully, without conversion to open surgery. Seven of the 9 patients underwent transanal endoscopic partial intersphincteric resection and the rest of 2 patients with tumor close to the dentate line underwent transanal endoscopic modified partial intersphincteric resection. The operation time and volume of intraoperative blood loss of 9 patients were (267±48)minutes and 50 mL(range, 30?60 mL), respectively. Five of the 9 patients underwent transanal specimen extraction, and 4 patients underwent specimen extraction by an abdominal incision. All 9 patients underwent transanal hand-sewn coloanal anastomosis and protective ileostomy, and two pelvic drainage tubes were indwelled. Transanal drainage tube was placed after anastomosis in 3 of 9 patients. Three cases had intraoperative adverse events and there were no intraoperative adverse event reported in the remaining 6 cases. The time to postoperative initial stoma exhausting and time to postoperative first semi-liquid food intake of 9 patients were 3 days(range, 2?4 days) and 5 days(range, 4?7 days), respectively. One case had Clavien-Dindo grade Ⅰ complication and 2 cases had Clavien-Dindo grade Ⅱ complication during postoperative 30 days and the rest of 6 cases had no postoperative complication. No anastomotic stricture, hemorrhage or urinary retention occurred in 9 patients. The duration of postoperative hospital stay and cost of hospitalization of 9 patients were 11 days(range, 9?23 days) and (6.8±1.3)×10 4 yuan, respectively. (2) Postoperative pathological examination: the diameter of tumor, the distance of distal resection margin, the number of lymph node dissected and the number of positive lymph node of 9 patients were (3.2±1.4)cm, 0.6 cm(range, 0.5?1.5 cm), 17±7 and 0(range, 0?7), respectively. The tumor histopathological type was adenocarcinoma with negative tumor nodule and nerve infiltration in all 9 patients. Only 1 case of 9 patients was found vascular tumor thrombus. The surgical specimens of all 9 patients showed negative for distal and circumferential margins and complete mesorectum. Results of postoperative pathological TNM staging showed that of 6 cases with preoperative T1-T2 staging tumors, 3 cases were classified as pT2N0M0 stage, and 3 cases were classified as pT2N1M0 stage, pT2N2M0 stage or pT3N1M0 stage, respectively. Three cases with preoperative T3 staging tumors were classified as ypT0N0M0 stage, ypT2N0M0 stage or ypT3N0M0 stage, respectively. (3) Follow-up: all 9 patients were followed up for 6 to 13 months, with a median follow-up time of 9 months. No local recurrence, distant metastasis or tumor-related death was found during follow-up. Of the 9 patients, only 1 case did not receive stoma closure and undergo anus function assessment, and the rest of 8 cases underwent stoma closure. Results of postoperative anus function assessment showed 5 cases of accessibility, 2 cases of mild impairment and 1 case of severe impairment. Results of urogenital function assessment showed 6 cases of the 8 male patients of mild impairment, 1 case of moderate impairment and 1 case of severe impairment in micturition function, respectively, and 3 cases of accessibility, 2 cases of mild impairment and 3 cases of moderate impairment in sexual function, respectively. The female patient underwent accessibility of sexual function and the six-item version of the female sexual function index was 25. Conclusion:Transanal endoscopic partial intersphincteric resection can be used for the treatment of ultra-low rectal cancer.
