Objective To investigate the effects of mTOR/S6K1 signaling pathway on the development of insulin resistantce. Methods 20 male C57BL/6 mice were divided into normal diet group (NC) and high fat diet group (HF).HF mice were fed with high fat diet for 14 weeks and insulin resistance was confirmed in all mice. We observed the morphology of pancreatic islet by HE staining. Serum insulin concentration was also evaluated by ELISA. Northern blot, Western blot and immunofluorescence were performed to detect mTOR and S6K1 mRNA and protein expression in skeletal muscle. Results As compared with NC group,HF group showed that the body weight and fasting serum insulin level were increased by 21.99%(P＜0.05) and 181.82%(P＜0.01) respectively;the area of pancreatic islet was significantly increased;glucose tolerance was impaired;expressions of mTOR mRNA (125.61±10.43 vs 100.00, P＜0.05) and protein (137.41±7.86 vs 100.00, P＜0.01) were significantly increased. And we also found an significant increase in total S6K1 mRNA (154.98±16.26 vs 100.00, P＜0.01) and protein (137.36±3.08 vs 100.00,P＜0.01) as well as pS6K1 protein (390.15±69.62 vs 50.59±16.65,P＜0.01)expression in HF group as compared with NC group.Conclusions mTOR/S6K1 signaling pathway plays an important role in the development of higt fat diet induced insulin resistance.

Objective To examine the effect of high intensity interval training(HIIT) and moderate intensity continuous training(MICT) on the body component,serum globular adiponectin and skeletal muscle autophagy in C57BL/6 mice.Methods Thirty-six four-week-old C57BL/6 mice were randomly assigned to the control group,MICT group and HIIT groups.The MICT group underwent 60 minutes' aerobic continuous treadmill training at 12 m/min(75％ VO2max) once a day,5 times/week for 6 weeks,while the HIIT group exercised for 1min at 20 m/min(85％ VO2max) followed by 1 min at 8 m/min (50％ VO2max) for alternating 12 cycles.The body weight,body mass index(BMI),total body water,fat mass and citrate synthase(CS) of the quadriceps femoris were measured using ImpediVET experimental animal body composition analyzer.Mice were sacrificed after the analysis,and the level of serum gAcrp30 was detected using the enzyme linked immunosorbent assay.Western blotting was used to detect the expression of pAMPK-Thr172,LC3II/I,Beclin1 and p62 protein in skeletal muscle tissues.Results After 6-week exercise,the body weight of MICT and HIIT mice decreased significantly compared with the sedentary control group.BMI and fat mass of the HIIT group were significantly lower than the control group,but there were no significant differences between the MICT and control groups in the above two measurements.The activity of CS and serum gAcrp30 in HIIT group was significantly higher than the control group.Moreover,the expression of pAMPK-Thr172,LC3II/I and Beclin1 increased significantly in the skeletal muscle after HIIT intervention while the expression of p62 decreased compared with the control group.Conclusion Compared with the MICT,HIIT has more significant effects to reduce body fat and BMI,and activate the autophagy of skeletal muscles.

Objective:To investigate the relationship between cardio-metabolic abnormalities in the first trimester and adverse pregnancy outcomes (APO).Methods:This cohort study recruited singleton pregnancies in the first trimester (6-13 +6 weeks of gestation) from Shenzhen Maternal and Child Health Care Hospital between January 1, 2021, and October 31, 2022. Cardiometabolic markers, including body mass index (BMI), blood pressure, fasting plasma glucose (FPG), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG), were recorded during the first trimester. Incidence of APO, including gestational hypertension, preeclampsia, gestational diabetes mellitus, preterm birth, fetal growth restriction, small for gestational age infant, and placental abruption, was documented. Cardiovascular metabolic abnormalities in the first trimester were defined as meeting one or more of the following criteria: elevated BMI (BMI≥24 kg/m2), elevated TG (TG≥1.7 mmol/L), decreased HDL-C (HDL-C<1.0 mmol/L), elevated blood pressure (systolic pressure≥130 mmHg (1 mmHg=0.133 kPa) and/or diastolic pressure≥85 mmHg), elevated FPG (FPG≥5.6 mmol/L). Enrolled women were categorized into abnormal cardio-metabolic and normal cardio-metabolic groups. Poisson regression was employed to analyze the association between cardio-metabolic abnormalities in the first trimester and APO. Results:The study included 14 197 pregnant women with an age of (32.0±4.1) years. There were 8 139 women in the normal cardio-metabolic group and 6 058 women in the abnormal cardio-metabolic group. Women with cardio-metabolic disorders in the first trimester had a younger gestational age and higher incidence rates of preterm birth, gestational hypertension, preeclampsia, and gestational diabetes mellitus (all P<0.05). In multivariable Poisson regression, elevated BMI ( RR=1.22, 95% CI 1.15-1.29), elevated FPG ( RR=1.59, 95% CI 1.38-1.82), elevated TG ( RR=1.22, 95% CI 1.13-1.31), and elevated blood pressure ( RR=1.50, 95% CI 1.39-1.63) were independent risk factors for APO, while decreased HDL-C ( RR=0.93, 95% CI 0.70-1.23) was not. Elevated blood pressure ( RR=5.57, 95% CI 4.58-6.78), elevated BMI ( RR=1.71, 95% CI 1.40-2.09), and elevated TG ( RR=1.38, 95% CI 1.10-1.74) had the greatest impact on the risk of developing preeclampsia. Elevated FPG ( RR=1.70, 95% CI 1.45-1.99) had the greatest impact on the risk of gestational diabetes. Conclusions:Elevated blood pressure, BMI, TG and FPG in the first trimester are closely related to APO.
