OBJECTIVE:To observe the clinical efficacy of pegylated interferon α-2a(Peg-INFα-2a)combined with adefovir (ADV)in the treatment of HBeAg-positive chronic hepatitis B (CHB). METHODS:An open randomized controlled clinical trial was performed. According to random number table,70 patients with HBeAg-positive chronic hepatitis B were divided into observa-tion group and control group,with 35 cases in each group. Observation group received Peg-INF α-2a combined with ADV,and control group was treated with Peg-INF α-2a only. Therapeutic efficacy and safety evaluation were evaluated after 24 and 48 weeks of treatment. RESULTS:After 24 weeks of treatment,ALT normalization rate of observation group and control group were 51.43%and 25.71%,and HBV-DNA negative rate of 2 groups were 68.57% and 37.14% respectively,with statistical significance (P<0.05). There was no statistical significance between HBsAg negative rate and HBeAg negative rate (P>0.05). After 48 weeks of treatment,ALT normalization rate of observation group and control group were 77.14% and 54.29%,and HBeAg negative rate 54.29% and 31.43%,and HBV-DNA negative rate 82.86% and 42.86% respectively,with statistical significance(P<0.05).There was no statistical significance in HBsAg negative rate and ADR (P>0.05). CONCLUSIONS:Peg-INFα-2a combined with ADV have good clinical efficacy in the treatment of HBeAg-positive CHB,and it is better than Peg-INFα-2a monotherapy and has less ADR.

Depression is a serious mental disorder characterized by lasting anhedonia and anorexia .The pathophysiology of depression is complicated , which is related to many neuroendocrine disturbances .Increased levels of glucocorticoid hor-mones and hyperactivity of the hypothalamus pituitary adrenal ( HPA) axis are the most consistent and typical pathophysio-logical alternations in patients with major depression , which are possibly caused by altered functions of the receptor of glu-cocorticoid hormones , the glucocorticoid receptor ( GR) .Promoting the expression and function of GR and restoring the im-paired feedback inhibition of the HPA axis seem to be particularly important for the therapeutic efficacy of antidepressants . In this review, the role of GR in the development and resolution of depression is discussed .

Objective Establish a method for qualitative and quantitative analysis of paraquat dichloride in organs in rat by UPLC-MS/MS and study the rat animal model poisoned by intragastric administration of paraquat dichloride to investigate the postmortem distribution of paraquat dichloride in poisoning death rat. Methods The rats were given an intragastric administration of 1/2LD50 Paraquat dichloride. The rats were dissected at 0.5h, 2h, 4h, 8h, 12h, 24h, 48h, 72h respectively after the intragastric administration. The specimens of -the heart, liver, spleen, lung, kidney, brain, muscle, bladder and stomach-were collected and analyzed immediately. Qualitative and quantitative analysis were performed by UPLC-MS/MS. Results Within 4h, stomach is the main distribution organ. The content of paraquat dichloride is the highest in stomache and relatively low in other organs. The concentration of organization except stomach changed little within 4h. The concentration of stomach has a sharp decline after 4h. The concentration in organs except stomach has a sharp rise after 4h. There is a significant difference(P<0.05) between each organs and brain. Conclusion There was a postmortem maldistribution of paraquat dichloride in poisoning death rats and the concentration in organs changes with time. The analysis method of UPLC-MS/MS and postmortem distribution of paraquat dichloride can be applied to the forensic identification of paraquat dichloride poisoning death and provide direction for delete this part toxicology analysis.
