Chinese Journal of Applied Physiology 2014;30(3):247-250
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:It has been recently proved that either decreased number or impaired function of CD4+CD25+regulatory T cells(Treg)can lead to immune dysfunction.Deeper knowledge of CD4+CD25+Treg cells is crucial for a better understanding of the pathogenesis of many diseases,such as autoimmune diseases,graft-versus-host disease,and allergic disease.This study is aimed to investigate the correlation of CD4+CD25+Treg cells in patients with idiopathic thrombocytopenic purpura(ITP)and to analyze the possible immunopathogenesis. METHODS:The experiment was conducted in the laboratory of Institute of Hematology,Chinese Academy of Medical Sciences and Peking Union Medical College from June to September in 2007.After the patients and their relative signed informed consents, peripheral blood was obtained from ITP patients(n=27)and health people(n=15)admitted in the Hematology Hospital,Peking Union Medical College.All patients accorded with the standards of ITP diagnosis and curative effect.The amount of CD4+CD25+ Treg cells in peripheral blood of normal controls and ITP patients before and after therapy was detected by flow cytometry.For those 23 patients who received effective therapy,blood before and after therapy were both obtained,the mononuclear cells(MNCs)were isolated from peripheral blood by density gradient centrifugation,then reverse transcriptase polymerase chain reaction(RT-PCR) was used to analyze the expression of Foxp3 mRNA. RESULTS:The amount of CD4+CD25+Treg cells and the ratio of CD4+CD25+Treg to total CD4+T cells in peripheral blood of ITP patients were obviously decreased than those of the controls(P0.05),but the expression of Foxp3 mRNA in CD4+CD25+ Treg cells was significantly increased(P

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.

Objective To determine the influence of protein fusion on the biological characteris- tics of hymidine kinase(TK)and human immunodeficiency virus(HIV)Tat recombinant protein. Methods By utilizing polymerase chain reaction(PCR)technique,different fragments containing two,four or six glycines(Gly)were inserted between the HIV Tat gene and TK,and cloned into PBK vector.After testified by sequencing,the vectors were transfected into E coli.After induced by iso- propyl thiogalactose(IPTG),bacilli were collected and destructed by ultrasonic,the fusion proteins were determined by monoclonal antibody against HIV protein.HepG2 cells were incubated in DMEM supplement with 10?g/mL HIV-Gly(n)-TK(n=0,2,4,6)fusion protein,TK-HIV Tat and only HIV Tat.HepG2 cells in different groups were detected by immunofluorescence assay 24 hours after transduction with HIV Tat monoclonal antibody.The rate of apoptosis after cells were incubated with gencilovir(10?g/mL)for 3 days was determined by cell flow cytometry,while survival cell ratio was recorded by trypan blue.The data were analyzed by statistics(t-test).Results The Tat-Gly(n)-TK (n= 0,2,4,6)recombinant genes were constructed and inserted into PBK vectors,which were expressed in E coli and then purified.Cells in different groups,which were incubated with Tat-Gly (n)-TK(n=0,2,4,6)fusion proteins,Tat-TK fusion protein,TK-Tat fusion proteins or only Tat proteins respectively,were detected by immunofluorescence assay.The intensities of fluorescence in different groups were almost same,but the ratios of cell survival or apoptosis were different.The highest ratio of cells apoptosis(14.77%)was in the group that cellular culture medium was mixed with Tat-Gly(4)-TK fusion protein,followed by the groups containing 6,2 glycines or no TK gene in genes(4.30%,12.69% and 1.03%,respectively).There were significant differences between each 2 groups among the all groups(t-test,P
