Objective:To summarize the clinical features of out-of-hospital extracorporeal cardiopulmonary resuscitation(ECPR) patients and analyze the factors associated with discharge survival.Methods:The data of 54 patients with ECPR in the Emergency Center of the Second Hospital Affiliated to Zhejiang University School of Medicine from January 2020 to December 2023 were analyzed. Patients were divided into the survival group and death group based on their survival status within 30 days of discharge. Kaplan Meier method was used to draw the survival curve, and COX regression analysis was used to analyze the relevant factors of survival.Results:(1) A total of 54 patients with ECPR were included in this study. 17 (31.5%) cases were discharged alive, of which 10 (58.8%) had a good neurological prognosis, while 37 case (68.5%) died.(2) Kaplan-Meier survival analysis showed that patients who received first-witness CPR, had a lower-extremity perfusion line established, underwent IABP, achieved ROSC, had normal pH, and had an initial pupillary light reflex had a longer median survival time ( P < 0.05). (3) Univariate COX regression analysis showed that statistically differences in survival time among patients with ECMO times, hypoperfusion times, initial pupil sizes, and APACHEⅡ scores ( P < 0.05); (4) Multivariate COX regression analysis showed that APACHEⅡ score, initial pupil size, and IABP were independent predictors of survival of patients discharged from the hospital with emergency ECPR; (5) The concordance index of the COX regression model was 0.921. Conclusions:The survival model demonstrates good predictive accuracy. Healthcare professionals can use the APACHEⅡscore and initial pupil size on admission as important reference indicators to assist in determining patient prognosis, and to timely initiate IABP treatment, in conjunction with the patient’s condition, to improve the survival rate of patients discharged from the hospital.

Objective To analyze the health management situation of non-communicable chronic disease(NCD)in Chongqing City and Guizhou Province and its influencing factors.Methods A stratified random sampling method was used to select 16 representative primary medical and health institutions from Chongqing City and Guizhou Province as the research sites,and the data were collected through the combination method of qualitative and quantitative research.Results A total of 760 patients with NCD were surveyed,and the awareness rate,utilization rate and satisfaction rate of the NCD health management program all exceeded 84.2％,while the awareness rate,utilization rate and satisfaction rate of follow-up and categorical intervention were the lowest.The awareness rate of hypertension physical examination in the patients with＜60 years old was lower than that in the patients with 60-＜70 years old(OR=4.28,95％CI:1.43-12.81)and the pa-tients with ≥70 year sold(OR=3.16,95％CI:1.12-8.91);the utilization rate of diabetes screening in the patients with＜60 years-old was lower than that in the patients with ≥70 years old(OR=2.70,95％CI:1.08-6.76)and the awareness rate of hypertension physical examination was lower than that of the patients with 60-＜70 years old(OR=4.24,95％CI:1.01-17.75);the awareness rate of hypertension physical ex-amination in the patients in Chongqing City was higher than that in Guizhou Province(OR=0.15,95％CI:0.04-0.54)and the utilization situation was better than that in Guizhou Province(OR=0.13,95％CI:0.05-0.34).Conclusion The overall situation of NCD management services in Chongqing City and Guizhou Province is good,but the service quality of follow-up and classified intervention projects needs to be further improved.

Objective To explore the anti-depression mechanism of Kai-Xin-San(KXS)via regulation of neurogenesis in hippocampus of depression-like mice.Methods The extracts of KXS were prepared and the anti-depression effects of KXS were evaluated by behavioral tests on chronic unpredictable mild stress(CUMS)induced depression-like mice.Evaluating depression-like behavior in CUMS mice through sucrose preference test,forced swimming test,tail suspension test,and other methods.Neurogenesis in hippocampus were determined by immunofluorescence assay.In addition,effects of KXS on regulating nestin expression and Wnt/b-catenin signaling pathway were explored by western blotting analysis.Amounts of cortisol,corticotropin-releasing factor(CRF),adrenocorticotropic hormone(ACTH),brain-derived neurotrophic factor(BDNF)and nerve growth factor(NGF)were determined by ELISA tests.Mouse primary neural stem cells(NSC)was used to evaluate the effect of KXS on promoting its proliferation by immunofluorescence assay.In addition,effects of KXS on regulating nestin and Wnt/β-catenin signaling pathway were also explored by Western blotting analysis.Results KXS significantly ameliorated the depression-like behaviors in presence of increased sucrose preference rate and decreased immobile time of tail suspension and forced swimming.KXS significantly promoted the neurogenesis in the hippocampus and expressions of nestin,reduced the expressions of cortisol,CRF,ACTH,increased the expressions of BDNF,NGF,and regulated Wnt/β-catenin signaling pathway.KXS also promoted the proliferation of NSCs and expressions of nestin,enhanced the translocation of b-catenin into nucleus,and regulated the expressions of proteins of Wnt/β-catenin signaling pathway.Conclusion KXS promoted neurogenesis in hippocampus and regulated Wnt/β-catenin pathway,which might contribute to its antidepressant effect.

Entinostat plus exemestane in hormone receptor-positive (HR+) advanced breast cancer (ABC) previously showed encouraging outcomes. This multicenter phase 3 trial evaluated the efficacy and safety of entinostat plus exemestane in Chinese patients with HR + ABC that relapsed/progressed after ≥1 endocrine therapy. Patients were randomized (2:1) to oral exemestane 25 mg/day plus entinostat (n = 235) or placebo (n = 119) 5 mg/week in 28-day cycles. The primary endpoint was the independent radiographic committee (IRC)-assessed progression-free survival (PFS). The median age was 52 (range, 28-75) years and 222 (62.7%) patients were postmenopausal. CDK4/6 inhibitors and fulvestrant were previously used in 23 (6.5%) and 92 (26.0%) patients, respectively. The baseline characteristics were comparable between the entinostat and placebo groups. The median PFS was 6.32 (95% CI, 5.30-9.11) and 3.72 (95% CI, 1.91-5.49) months in the entinostat and placebo groups (HR, 0.76; 95% CI, 0.58-0.98; P = 0.046), respectively. Grade ≥3 adverse events (AEs) occurred in 154 (65.5%) patients in the entinostat group versus 23 (19.3%) in the placebo group, and the most common grade ≥3 treatment-related AEs were neutropenia [103 (43.8%)], thrombocytopenia [20 (8.5%)], and leucopenia [15 (6.4%)]. Entinostat plus exemestane significantly improved PFS compared with exemestane, with generally manageable toxicities in HR + ABC (ClinicalTrials.gov #NCT03538171).

BackgroundNowadays， idolatry is an important part of the spiritual life of secondary school students， making a significant impact on their physical and mental development. Previous research has examined the two-by-two relationship between idolatry， peer attachment， life satisfaction and perceived social support， but the potential mediating mechanisms between these variables remain to be explored. ObjectiveTo explore the mediating role of peer attachment and life satisfaction between idolatry and perceived social support， so as to provide references for mental health education for secondary school students. MethodsIn June 2022， 1 059 students currently enrolled in secondary school in Qiannan State， Guizhou Province were selected according to stratified random sampling method. In this study， assessment was performed using Celebrity Attitude Scale （CAS）， Peer Attachment Subscale from Revised Inventory of Parent and Peer Attachment （IPPA-R）， Satisfaction with Life Scale （SWLS） and Perceived Social Support Scale （PSSS）. Pearson correlation analysis was used for correlation test. Model 6 in the SPSS Macro Process 3.3 was used to examine the mediating effect of peer attachment and life satisfaction between idolatry and perceived social support in secondary school students. Results①CAS score indicated positive correlation with scores of IPPA-R Peer Attachment Subscale， SWLS and PSSS （r=0.117， 0.097， 0.115， P<0.01）. IPPA-R score indicated positive correlation with scores of SWLS and PSSS （r=0.279， 0.421， P<0.01）. SWLS score was positively correlated with PSSS score （r=0.552， P<0.01）. ②The direct effect of idolatry on perceived social support was significant （β=0.059， P<0.05）. Both separate and chain mediating effects of peer attachment and life satisfaction between idolatry and perceived social support were significant （95% CI： 0.007~0.130， 0.004~0.054， 0.001~0.016， P<0.01）. The three effects above respectively accounted for 33.56%， 13.54% and 3.93% of the total effect. ConclusionIdolatry can affect secondary school students' perceived social support both directly and indirectly through peer attachment and life satisfaction.
