Objective: To determine plasma levels of soluble tumor necrosis factor-related apoptosis inducing ligand (sTRAIL) and its soluble death receptor (sDR4, sDR5) in essential hypertension (EH) patients with left ventricular hypertrophy (LVH). Methods: Enzyme linked immunosorbent assay (ELISA) was used to measure plasma levels of sTRAIL, sDR4 and sDR5 in 50 EH + LVH patients (EH + LVH group), 50 EH patients without LVH (EH group) and 50 healthy subjects (healthy control group), and the results were compared and analyzed among three groups. Results: ① Compared with healthy control group and EH group, there were significant increase in plasma levels of sTRAIL [(0.95±0.11) ng/ml vs. (1.12±0.86) ng/ml vs. (1.74±1.19) ng/ml], sDR4[(2.38±0.32) pg/ml vs. (5.63±1.05) pg/ml vs. (8.72±1.14) pg/ml] and sDR5[(< 6 pg/ml) vs. (39.19±8.23) pg/ml vs. (78.21±11.2) pg/ml] in EH + LVH group, P<0.01 all; and levels of sDR4 and sDR5 in EH group were significantly higher than those of healthy control group (P<0.01 both), but there was no significant difference in sTRAIL level between the two groups (P>0.05); ② Pearson correlation analysis indicated that there were significant positive correlation among levels of sTRAIL, sDR4 and sDR5 in EH + LVH patients (r=0.325~0.410, P<0.05 or <0.01). Conclusion: Plasma levels of sTRAIL, sDR4 and sDR5 may be valuable indexes for prediction of left ventricular hypertrophy in patients with hypertension.

Objective:To analyze the relationship between free androgen index and insulin function in obese young men aged from 20 to 35.Methods:A total of 82 young obese men in Obesity Clinic from February to October 2019 were enrolled in the study. The subjects were divided into 3 subgroups according to free androgen index level tertiles. The blood glucose and insulin levels were tested after oral glucose tolerance test. Homeostasis model assessment for insulin resistance (HOMA-IR), homeostasis model assessment for β cell function (HOMA-β), insulin secretion index, and insulin sensitivity index (Matsuda index) were used to evaluate β cell function in oder to analyze the relationship between free androgen index and insulin function.Results:In young obese men, participants with higher free androgen index levels exhibited less waist circumference, lower body mass index, 1 h postprandial insulin, 2 h postprandial insulin, HOMA-IR level but with a higher total testosterone, sex hormone binding globulin, and Matsuda index level (all P<0.05). There was a negative correlation between the free androgen index and the HOMA-IR ( r=-0.386, P=0.016), and the correlation tended to a linear trend after adjustment for age, sex, body mass index, and waist circumference ( Ptrend=0.034). Free testosterone was positively correlated with Matsuda index ( r=0.280, P=0.004), but the correlation disappeared after adjustment ( Ptrend=0.623). The results of further regression analysis showed that the level of free testosterone index decreased by 14.1% ( OR=0.869, 95% CI0.767-0.984, P=0.028) for each increase of HOMA-IR after adjustment. Conclusion:The level of free testosterone index is a predictor of insulin resistance in obese young men, but the association between this parameter and insulin sensitivity may be caused by obesity.

AIM: To investigate the alterations of tear film after sutureless large incision manual cataract extraction (SLIMCE). METHODS: Sixty-eight SLIMCE operation eyes were studied with slit-limp microscope, break- up time (BUT), SchirmmerⅠtest (SⅠt),and fluorescence(FL) to observe the alterations of tear film at different time points in postoperation. Impression cytology and microphoto-analyses technique were also applied to observe the goblet cells at different time points postoperation(7,14,30,60,90 days). RESULTS: Subjective complaint of dry eye within 90 days after the operations were significantly increased compare with preoperations(5-27,23,19,16,13; 2-16,14,8,6,3). The schirmmer Ⅰ test were greatly increased in 14 days postoperation(10.1±4.5;15.0±4.7,13.8±5.7),the mean scores of fluorescence increased (0-17,9,5;0-8,3,1) and the mean break-up time decreased in 30 days post-operation(10.3±2.2;5.5±2.3,7.0±2.4,7.9±2.2) (P<0.05). CONCLUSION: SLIMCE operation have effect on the stability of tear film.

OBJECTIVETo study the molecular mechanism of Yangjing Zhongyu Decoction (YZD) n-butanol extracts (ZDC) and ethyl acetate extracts (YSYZ) in reducing androgen in porcine granulose cells by mitogen-activated protein kinase (MAPK) pathway.

METHODSPorcine granulose cells were isolated and cultured. They were inoculated by MAPK inhibitor PD98059 at different concentrations, and then they were divided into the blank control group (0), 1, 3, 10, and 25 micromol/L groups. After 24-h culture the cytochrome P450c17a (CYP17) mRNA expression level was detected using Real-time fluorescent quantitative PCR. Contents of androgen (testosterone) in the supernate were detected using RIA and optimal PD98059 concentration screened. After intervened by 10 micromol/L PD98059 for 24 h, the culture solution was intervened by effective ingredients of with or without YZD or YSYZ at various concentrations (0, 1 , 5, 25, 50 mg/mL) at various time points (3, 6, 18, 24 h). Expression levels of p-ERK1/2, c-Fos and CYP17 were detected by Western blot. Testosterone content in the supernate was determined by radioimmunoassay (RIA).

RESULTSTen pLmol/L PD98059 could obviously decrease p-ERK1/2 protein expression and increase CYP17 mRMA expression, and elevate testosterone content in the supernate (P < 0.05). ZDC and YSYZ at 25 ng/mL could increase p-ERK1/2 protein expression and c-Fos levels, and reduce CYP17 protein expression, and lower testosterone content in the supernate after 6-h intervention (P < 0.01).

CONCLUSIONEffective ingredients of YZD could reduce androgen production in porcine granulose cells through increasing activities of MAPK.
