ObjectiveTo investigate the effect of NGF on apoptosis of HSC in vitro and explore the possible mechanism.MethodsHSC was incubated with different concentrations of NGF.HSC apoptosis was identified by FCM.The expressions of apoptosis-regulating proteins Caspase-3,p53 and Bcl-2 of HSC after apoptosis induced by NGF were examined by immunohistochemical staining.Expressions of NGF and p75NTR were detected by immunofluorescence.ResultsApoptosis index of HSC was higher than that of control group [(22.36±9.51)％ vs (5.88±1.36)％] after treated with NGF (100 ng/ml) (P＜0.05).After incubating with 100 ng/ml NGF for 24 h,the positive expression rates of p53 and Caspase-3 of HSC increased significantly than those of control group [(78.41±4.00)％ vs (34.96±3.84)％,(39.26±1.57)％ vs (9.27±1.01)％,P ＜0.05].The positive expression rate of Bcl-2 protein of HSC significantly decreased compared with that of control group (18.12±1.38)％ vs (91.53±2.98)％ (P＜0.05).When HSC was stimulated with 100 ng/ml NGF for 24 h,the average optical density of NGF increased significantly than control group (6.53±1.40 vs 1.77±0.17) (P＜0.05),while the expression of p75NTR was not significantly changed (3.52±0.36 vs 4.24±0.38) (P＞0.05).ConclusionsThe mechanism of NGF to induce HSC apoptosis may be associated with the up-regulating expression of Caspase3,P53 and down-regulating expression of Bcl-2 on HSC.NGF could be used as an initiating factor and effect factor to increase the expression of NGF on HSC,but it had no significant effect on p75NTR expression.

Objective To compare the blood glucose level and associated hypoglycemia risks between group of insulin glargine combined with repaglinide and group of mixed insulin in the treatment of type 2 diabetes in the elderly. Methods Sixty four type 2 diabetes patients (age≥60 years) with inadequate glyeaemic control by drugs were divided into 2 groups randomly: glargine group (32 cases) and mixed insulin group (32 cases). In glargine group, 32 patients were given repaglinide before breakfast, lunch, supper respectively and injection of glargine hypodermically once at 22 o'clock every night, while the 32 patients in mixed insulin group were injected with the mixed insulin (Novolin 30R) hypodermically before breakfast and supper respectively for 16 weeks. The dose of repaglinide and insulin were adjusted every 3 days according to the level of fasting glucose (FPG)and postprandial glucose (PPG), reaching the aim of FPG less than 7.2 mmol/L and PPG less than 10mmol/L. The blood glucose level and the incidence of hypoglycemia were observed. Results The daily glucose profile and the level of HbAlc of the 2 groups dropped obviously after 16 weeks treatments (all P<0. 05). At the end of the experiment, the PPG of lunch and supper, and the level of HbAlc were markedly lower in glargine group than in mixed insulin group (all P<0. 05), and the body mass index (BMI) increased markedly in mixed insulin group compared with pre-experiment (P<0. 05), but no significant change was found in glargine group (P>0. 05). The incidence of hypoglycemia in glargine group was lower than that in mixed insulin group (2 patients in glargine group, 12 patients in mixed insulin group, P<0.05). Conclusions Both of the mixed insulin and glargine combined with repaglinide have visible effects on controlling the blood glucose, but the latter has better efficacy, lower risk of hypoglycemia and lower increase of BMI than the former.

Objective To observe therapeutic effects of HuGanJieXian decoction on rats hepatic fibrosis induced by tetrachloride. Methods Rat models of hepatic fibrosis were constructed by intraperitoneal injection of tetrachloride.HuGanJieXian decoction composed of low, middle, and high dose curcumin were given to these rats respectively at the same time. Sho-saiko-to compound treatment group and Fufangbiejiarangan Tablets treatment group were made as positive control groups. After twelve weeks, all rats were executed. Serum samples were kept for measuring serum levels of PC-Ⅲ, LN, and HA. Left livers were extirpated for pathologic examination including H.E and Masson stainings. Grade of hepatic fibrosis were evaluated according to SSS system. The levels of superoxide dismutase (SOD) and malondialdehyde (MDA) of supematant centrifugated from hepatic tissue homogenate were detected. Results Serum levels of PC-Ⅲ, LN, and HA were depressed obviously in decoction groups compared with those of fibrotic group (P<0.05) , especially in the low-dose curcumin group.HuGanJieXian Decoction could increase the level of SOD and decrease the level of MDA (P<0.05) , especially in the low-dose curcumin group. Staining of H. E and Masson showed that degrees of hepatic fibrosis in decoction groups were improved obviously compared with that of the fibrotic group. Conclusion HuGanJieXian Decoction can improve rat hepatic fibrosis, the mechanism of this effect may be associated with protecting hepatic cell membrane and anti- peroxidative damage.
