Objective To analyze the relationship between carotid intima-media thickness (CIMT) and metabolic syn?drome (MS), and explore risk factors for CIMT incrassation in Tianjin policemen. Methods Fifty MS patients (MS group) and 50 healthy people (control group) in health examination of Tianjin policemen were enrolled in this study. The question?naire survey(family history,past medical history,present history,living habits and occupational stress factors) were recorded in two groups of patients. The blood indicators (fasting plasma glucose, triglycerides, total cholesterol, high density lipopro?tein cholesterol, low density lipoprotein cholesterol, homocysteine) were detected. The color Doppler was used to measure CIMT incrassation, and incrassation ratio was calculated. The relative indicators were compared between two groups. The lo?gistic regression model was used to analyse the influencing factors of carotid artery intima-media thickness. Results CIMT and CIMT incrassation ratio (communis, internal and external carotid) were significantly higher in MS group than those of control group (P<0.01). The risk factors for CIMT included family history of hypertension, chronic stress, smoking, family history of diabetes, high fat diet and high homocysteine levels, and dairy products were protective factors for CIMT incrassa?tion. Conclusion The reason of carotid artery intima-media thickness is diversity. The healthy lifestyle and clinical inter?vention to retard CIMT are advocate, which are conducive to the control of atherosclerosis.

Objective This study was to observe the effects of ciliary neurotrophic factor(CNTF)gene mediated by ultrasound microbubbles intraocular transfer on visual function and retinal ganglion cell(BGCs)after optic nerve injury. Methods Fifty-five adult Sprague-Dawley(SD)rats were divided into 6 groups randomly,including normal control group(n=5),sham injury group(n=10),simple injury group(n=10),naked plasmid group(n=10),plasmid+ultrasonic irradiation group(n=10)and ultrasound microbubbles group(n=10).The model of optic nerve injury Was made by forceps clip on the fight optic nerve.and the corresponding intervene was performed in different groups.Flash visual evoked potential(F

Objective To observe the effect of autophagy inhibitor on the activation of alcohol induced hepatic stel-late cells, and the mechanisms thereof. Methods HSC-T6 cells were cultured in vitro and divided into four groups, includ-ing blank control group, alcohol group, 5 mmol/L 3-MA+alcohol group (low alcohol group) and 10 mmol/L 3-MA+alcohol group (high alcohol group). RT-PCR was used to detect the expression levels ofα-smooth muscle actin (α-SMA) and typeⅠcollagen. The levels of LC3Ⅱ,α-SMA and typeⅠcollagen were detected by Western blot assay. The cell viability of HSC-T6 was detected by MTT assay. Results The mRNA expressions ofα-SMA, typeⅠcollagen and the protein of expressionsα-SMA, typeⅠcollagen and LC3Ⅱwere significantly up-regulated in alcohol group compared with those of control group (P<0.05), while the expressions of those parameters were significantly down-regulated in 10 mmol/L 3-MA+alcohol group (P<0.01). The mRNA and protein levels ofα-SMA and typeⅠcollagen were significantly decreased in two 3-MA-treated groups compared with those in alcohol group (P<0.05). Meanwhile, compared with the 5 mmol/L 3-MA+alcohol group,the protein expressions ofα-SMA, typeⅠcollagen and LC3Ⅱwere significantly decreased in10 mmol/L 3-MA+alcohol group (P < 0.05 ). Compared with the alcohol group,there was significantly lower proliferation activity in all two 3-MA-treated groups (P<0.05). Conclusion 3-MA can inhibit the protein expression of LC3Ⅱ,α-SMA and typeⅠcollagen induced by alcohol in HSC-T6 cells, and inhibit the proliferation of HSC cells.

Aim To investigate the effects of panax nonstaining saponins ( PNS ) on the apoptosis of renal cells induced by cisplatin through the path of mitochon-drion . Methods Male Sprague-Dawley( SD) rats were randomized divided into normal control group, cisplatin model group and the cisplatin+PNS group,with 12 rats of each group. Animals were sacrificed to determine the N-acetyl-β-D-Glucosaminidase ( NAG ) in urine, blood urea nitrogen ( BUN) and serum creatinine ( Cr) concentrations after 8d of intraperitoneal injection. HE-staining was employed to observe renal pathologies. Transmission electron microscopy ( TEM ) was em-ployed to observe the mitochondria of the rats′ injured kidney region. TUNEL staining was employed to detect the distribution of apoptotic cells. Immunnohistochem-istry was used to detect Bax and caspase-9 expression, and expression of Bcl-2 protein was detected by West-ern blot. Results Compared with the normal control group, contents of BUN, serum Cr and urinary NAG levels of rat in the cisplatin model group were increased ( P <0. 01 ) , and some mitochondria of the epithelial cells of renal tubules got injured seriously. The apopto-sis rate of kidney cell was increased ( P<0. 01 ) . The expression of Bax,caspase-9 and Bcl-2 proteins was in-creased ( P < 0. 01 ) . Compared with the cisplatin model group, contents of BUN, serum Cr and urinary NAG levels of rats in the cisplatin model group were decreased ( P <0. 01 ) , and some mitochondria of the epithelial cells of renal tubules were significantly im-proved. The apoptosis rate of kidney cell was decreased ( P<0. 01 ) . The expression of Bax and caspase-9 pro-tein was decreased (P<0. 01),but Bcl-2 protein was increased ( P < 0. 01 ) . Conclusion PNS may in-crease the expression of Bcl-2 protein and decrease the expression of Bax and caspase-9 proteins, which may play a protective role in cisplatin nephritic damage.
