To study the effects of growth hormone on function of T lymphocytes. Methods: Tne expression plasmid PcDNA-GHcDNA was constructed,then the plasmids were transfected into Jurkat cells,on the other hand,Jurkat cells were treated with different doses ofrhGH, to investigate the effect of overexpression GH and rhGH on function of T lymphocytes. Results: Overexpression GH could increase the ex-pression of IL-2R(140%) and secretion of IL-2(160%) and IFN-γ( 198% ) in Jurkat cells after PHA activation,but these data were broughtdown by the treatment of GH antibody. rhGH could also enhancer the function of T lymphocytes after PHA activation. Conclusion: These resultssupport the idea that GH is an autocrine and paracrine factor, and can regulate the function of T lymphocytes.

Objective To evaluate the clinical significance of determination for serum insulin like growth factor binding protein 3 (IGFBP 3) protease activity. Methods Serum IGFBP 3 protease activity in normal persons, parturient pregnant women, acromegalic patients and patients with growth hormone deficiency (GHD) was determined by Western blot technique. Results Serum IGFBP 3 protease activity in parturient pregnant women, acromegalic patients,normaladultsanduntreatedGHDpatientswere (75.2?2.2)%, (68.6?3.9)%, (22.7?3.1)% and (13.4?4.2)% respectively. Serum IGFBP 3 protease activity in GHD increased to (29.0?6.8)% after treatment with recombining human somatropin (rhGH) for six months. Conclusions Serum IGFBP 3 protease activity is modulated by GH and affects serum levels of members of GH IGF Ⅰ axis.

Prolactin (PRL) is a multi-functional hormone mainly from pituitary gland. PRL receptors exist ubiquitously in all tissues and organs of immune system and PRL modulates local and systemic immune activities. PRL is involved in many physiological and pathological immune responses. The function of PRL in autoimmune diseases, organ transplantation and tumor occurrence has been explored in recent years. This article is to review the progress of prolactin in the immunology-related field.

Objective To observe the traditional Chinese medicine (TCM) and umbilical treatment on diarrhea-predominant irritable bowel syndrome(IBS-D)with mental disorders. Methods Thirty-seven cases with IBS-D were randomized into a treatment group(33 cases) and a control group(31 cases). The treatment group was given Shugan-Jianpi TCM decoction and pepper umbilical dressing. The control group was given Pinaverium Bromide Tablets and Flupentixol and Melitracen tablets. After having been treated for 4 weeks, Hamilton Anxiety Scale(HAMA), Hamilton Depression Scale(HAMD), IBS Symptom Severity Scale(IBS-SSS), IBS quality of life questionnaire (IBS-QOL) were determined. Results After the treatment, HAMD, HAMA, IBS-SSS in the treatment group and the control group all significantly decreased (the treatment group t=14.280, 13.530, 18.847,the control group t=11.514, 9.424, 13.829, P<0.01), and IBS-QOL increased markedly(t=-16.848, -11.712, P<0.01). Compared with HAMA, IBS-SSS and IBS-QOL in treatment group, the control group showed statistical difference(t=-3.183, -2.549, 3.904, P<0.01 or 0.05). The total effective rate of the treatment group was 94%higher than 75%of the control group(χ2=4.727, P<0.05). Conclusion Shugan-Jianpi TCM decoction and pepper umbilical dressing can improve the clinical symptoms and psychological symptoms and improve the quality of life of IBS-D patients.

Stromal preadipocytes from human omental adipose tissues were isolated with enzyme-digesting method,and cultured for inducing differentiation.Preadipocyte factor-1 was abundant during preadipoeyte stage,whereas lipoprotein lipase and PPARγ2 mRNA were rapidly up-regulated at early stage of differentiation and CCAAT/enhancer binding protein expression was increased rather late.In addition,resistin expression and secretion was primarily detectable in preadipocytes,leptin was gradually increased during adipogenesis,whereas adiponectin appeared specifically in mature adipocytes.Insulin-like growth factor-Ⅰ secretion was remarkably detected in both preadipocytes and mature adipocytes.

Objective To analyse the clinical significance of LHRH exciting test in the differential diagnosis of constitutional delayed puberty (CDP) and hypogonadotropic hypogonadism (HH). Methods Eighty-one cases from 1982 to 1998 were investigated and followed up. They were all at genital stage Ⅰ. After injection of 100 ?g LHRH, the blood samples (3 ml) were taken at -15, 0, 15, 30, 45, 60, 90 and 120 min. The serum LH and FSH levels were determined by radioimmunoassay. Then they were followed up every 3-24 months. After they received LHRH exciting test, they were followed up until over 18 years old. According to their puberty development status, they were divided into 3 groups, normal group (n=34),CDP group (n=16) and HH group (n=31),andthemeanage,whenthey received LHRH exciting test, was (10.2?0.9, range 9-14) years, (16.0?1.0, range 14-18) years and (17.1?1.4, range 16-22) years respectively. Results There were no significant differences in serum LH baseline level and peak time in normal, CDP and HH groups, but the serum LH peak level, LH increment (peak LH level minus baseline LH level), LH increment ratio (peak level/baseline level of LH) and the area under LH curve (AUC LH ) of normal group were significantly higher than those of CDP group and HH group (all P
