OBJECTIVE To explore the mechanism of the active ingredient compatibility(quercetin, quercitrin and kaempferol at a mass ratio of 2∶9∶3)of Dimocarpus longan Lour. leaves(abbreviated as CDL) on ameliorating glucose and lipid metabolism disorders in type 2 diabetes mellitus (T2DM) rats. METHODS SD rats were randomly divided into blank control group, model group, metformin hydrochloride group (100 mg/kg), and CDL high-, medium- and low-dose groups (280, 140, 75 mg/kg), with 10 rats in each group. Rats in the blank control group were fed with standard chow, while rats in the other groups were given high-sugar and high-fat diet combined with intraperitoneal injection of streptozotocin to establish the T2DM rat model. After successful modeling, rats in each administration group were given corresponding drug solution, and rats in the blank control group and model group were intragastrically administered with equal volume of pure water, once a day, for consecutive 4 weeks. Fasting blood glucose (FBG) was detected at fixed time every week. The curves of oral glucose tolerance test (OGTT) and intraperitoneal insulin tolerance test (IPITT) were plotted, and the area under curve (AUC) was calculated. The pancreatic islet function indexes [fasting insulin (FINS), homeostasis model assessment of insulin resistance (HOMA-IR), insulin sensitivity index (ISI)],blood lipid indexes [total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C)] and hepatic glycogen content were determined. The pathological morphological changes of liver and pancreatic tissues were observed. The protein and mRNA expression levels of molecules related to phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway in liver tissues were detected. RESULTS Compared with the blank control group, the FBG, AUC of IPITT curve, AUC of OGTT curve, HOMA-IR, the levels of FINS, TC, TG and LDL-C, as well as the protein and mRNA expression of phosphatase and tensin homolog, forkhead box protein O1 and glycogen synthase kinase-3β in liver tissues were significantly increased in the model group ( P <0.05). ISI, the levels of HDL-C and hepatic glycogen content, along with the protein and mRNA expression of PI3K, insulin receptor substrate-1, Akt and protein expression of phosphorylated Akt in liver tissues were markedly decreased ( P <0.05). In model group rats, the arrangement of hepatocytes was irregular, the overall structure of pancreatic lobules was disordered, and a large number of inflammatory cell infiltration was observed. Compared with the model group, most of the above quantitative indexes were significantly reversed in the CDL high-dose group ( P <0.05), and the pathological lesions of liver and pancreas were obviously alleviated. CONCLUSIONS CDL can regulate glucose and lipid metabolism disorders, elevate insulin sensitivity and relieve insulin resistance in T2DM rats. Its mechanism may be related to the activation of the PI3K/Akt signaling pathway.

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.

ObjectiveTo analyze the effect of O3 pollution on outpatient visits for respiratory diseases in a district of Shanghai. MethodsWe collected the respiratory disease outpatient data, and atmospheric and meteorological data of from a suburban general hospital in Shanghai from 2015 to 2017. A time-series analysis by generalized additive model was conducted to examine the relationship between O3 pollution and daily outpatient visits. ResultsThe daily outpatient volume for respiratory diseases was 831. The daily 8 h median concentration of O3 was 101.04 μg·m-3. The excess relative risk was 0.461% (95%CI: 0.240%‒0.682%) at lag3. Stratified by gender and age, females, child and the aged had higher risk of respiratory diseases. In the double-pollutant model, PM2.5 and PM10 increased health effects, while CO reduced health effects. ConclusionThe increase of O3 concentration can increase the daily outpatient volume of respiratory diseases.
