OBJECTIVETo investigate the effects of recombinant human growth hormone on serum lipid in aged male patients with chronic heart failure (CHF).

METHODSEighty seven patients with chronic heart failure(> or = 60 years old) were randomly divided into 2 groups: the CHF control group (n = 46) who received regular therapy and the CHF experimental group (n = 41) who received regular therapy and recombinant human growth hormone. The treatment would be continued for 3 months. Another group was normal control group (n = 10). The detection of serum growth hormone (GH), insulin-like growth factor (IGF-1), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) was carried out before and after treatment in the participants.

RESULTSBefore treatment, the levels of GH and IGF-1 were not significantly different among groups. After treatment, the levels of GH (0.71 +/- 0.34 vs 0.96 +/- 0.48) and IGF-1 (95.64 +/- 21.11 vs 111.64 +/- 23.14)in CHF experimental group were higher than those before the treatment. In CHF control group, the levels of GH(0.81 +/- 0.32 vs 0.79 +/- 0.29) and IGF-1 (97.82 +/- 19.74 vs 99.65 +/- 20.11) had no significant change after the treatment. After treatment, the levels of GH (0.96 +/- 0.48 vs 0.79 +/- 0.29) and IGF-1 (111.64 +/- 23.14 vs 99.65 +/- 20.11) in CHF experimental group were higher compared with that of CHF control group. Before treatment, the serum levels of LDL-C, HDL-C, TC and TG had no significant difference among groups. After treatment,the levels of LDL-C (2.11 +/- 0.82 vs 1.76 +/- 0.51) and TC (3.78 +/- 1.34 vs 3.21 +/- 1.17) in CHF experimental group were lower than those before the treatment. However, the levels of HDL-C (1.10 +/- 0.31 vs 0.99 +/- 0.28)and TG (1. 89 +/- 1.07 vs 1.66 +/- 0.95) had no significant change after the treatment compared with before treatment. In CHF control group, the serum lipid levels had no significant change after the treatment.

CONCLUSIONAs the treatment of rhGH for aged male patients with chronic heart failure, GH influences lipid metabolism, which reduces the level of LDL-C, TC. However GH has no effects on the serum HDL-C and TG level. With the treatment of rhGH for long-term, lipid metabolism should be paid attention,and the treatment for blood lipid reduction should be adjusted in time.

Aim To investigate changes of MAP2 expression level in rat hippocampal pyramidal cells induced by chronic stress, and to explore effects of tianeptine on them. Methods 25 rats were divided randomly into three groups:Control group,Stress group and Stree-tianeptine group. The forced-swimming was performed to rats in stress group and stress-tianeptine. Using the immunohistochemistry and the computerized image technique, expression levels of phosphorated MAP2 and the number the Positive cells were assayed quantitatively in each group. Results Compared with control group (149.34?1.81), the phosphorated MAP2 average gray degree in pyramidal cells of stress group (144.99?4.40) was significantly lower, that of the stress-tianeptine group (148.84?2.73) was significantly higher than that of stress group; The number of phosphorated MAP2 positive cells in stress group (40.36?1.35) was significantly less compared withthat of control group (42.73?1.56); that of stress-tianeptine group (42.14?1.62) was significantly more than that of stress group. Conclusion It is suggested that tianeptine could inhibit the enhancement of phosphorated MAP2 expression in hippocampal pyramidal cells induced by chronic stress.

Objective:To evaluate the short-term effect of robotic pancreaticoduodenectomy (RPD) and laparoscopic pancreaticoduodenectomy (LPD) in the treatment of ampullary and periampullary tumor systematically.Methods:A systematic search of the PubMed, Embase and Cochrane library database using the key words "pancreaticoduodenectomy, duodenopanreatectpmy, whipple, laparoscopic, robotic, Da Vinci" . A systematic search of the Sinomed, Wangfang, VIP and CNKI databases including the key words "胰十二指肠切除" , "腹腔镜" , "机器人" , "达芬奇" . To investigate the differences of the conversion rate of laparotomy, incidence of postoperative complications, and the postoperative hospital stay between the RPD group and the LPD group. The software RevMan5.3 was used in this meta-analysis.Results:A total of 4 retrospective cohort studies and 1 001 patients were included in this meta-analysis, including 451 patients in the RPD group and 550 patients in the LPD group. The results of the meta-analysis showed that there were significant differences between RPD group and LPD group for the conversion rate laparotomy ( OR=0.35, 95% CI: 0.24-0.50, P<0.05). There were no significant differences between RPD group and LPD group for the incidence rate of overall complication( OR=1.23, 95% CI: 0.95-1.58, P>0.05), hemorrhage ( OR=0.71, 95% CI: 0.50-1.00, P>0.05), pancreatic fistula ( OR=1.09, 95% CI: 0.80-1.49, P>0.05), delayed gastric empty ( OR=0.81, 95%CI: 0.57-1.14, P>0.05) and hospital stay after surgery ( WMD=-2.87, 95% CI: -1.44-1.70, P>0.05). Conclusions:RPD is as safe as LPD, with the same complication rate. Therefor it is worthy for further application in medical institutions with relevant conditions.
