BACKGROUND:Many foreign studies confirm that recombinant human growth hormone (rhGH) is a safe and effective agent for treatment of idiopathic short stature (iSS), but there are no long-period and systematical researches reported in China.OBJECTIVE: To observe the promoting effect of rhGH on the growth of children with ISS.DESIGN: Case-control observation.SETTING: Department of Pediatrics, the Affiliated Hospital of Medical College of Qingdao University.PARTICIPANTS: Ninety-eight children with ISS who were treated in the Department of Pediatrics, the Affiliated Hospital of Medical College of Qingdao University during December 2004 to March 2006 were involved in this study.Informed consents were obtained from the guardians of these children with ISS. According to the etiological factors, the children were assigned into 2 groups: ISS group (n =30) and growth hormone deficiency (GHD) group (n =68).METHODS : The children in ISS group and GHD group received subcutaneous administration of home-made rhGH (Jinsai Pharmaceutical Co.,Ltd., Changchun at 0.15 IU/(kg ·d) and 0.1 IU/(kg ·d) respectively before sleeping within 6 months.The body height, body mass and bone age were measured before, 3 and 6 months after treatment. The local region of injection was observed and the growth rate was calculated. Bone age was calculated by graphic atlas method and body height was predicated by BP method.MAIN OUTCOME MEASURES: Body height, body mass, bone age and growth rate of children in two groups before, 3 and 6 months after treatment.RESULTS: All the 98 children wereinvolved in the result analysis, without deletion. ①Intragroup comparison: The body height, growth rate of children in two groups 3 and 6 months after treatment were significantly superior to those before treatment [ISS group: body height:(126.5±9.4), (129.1±8.6), (121.1 ±11.0) cm (P ＜ 0.01), growth rate: (7.3±2.9), (7.5±2.7),(3.5±2.1) cm/year (P＜ 0.01); GHD group: body height: (111.0±13.0),(114.0±13.0),(108.0±12.0) cm(P＜ 0.01),growth rate: (13.2±3.5), (13.5±3.6), (4.0±2.9) cm/year(P ＜ 0.01)]. Six months after treatment, body height was increased in 27 of 30 children in ISS groups, and in all the 68 children in GHD group. ② Intergroup comparison: The growth rate of children in GHD group was concurrently higher than that in ISS group 3 and 6 months after treatment. ③Adverse reaction and side effect: During the treatment, hypothyroidism was observed in 2 children within 1 to 3 months of treatment,but there was no influence on growth rate after oral administration of thyroxin tablets. Local red swelling of skin was observed in another patient, which stopped automatically after one week duration, but the injection continued.CONCLUSION: Home-made rhGH is a safe and effective reagent for treatment of ISS. It can obviously enhance the body height and growth rate of children. Whereas the inhomogeneity of treatment effect does exist, what's more, therapeutic effect in ISS children is inferior to that in GHD children.

AIM To investigate whether pioglitazone can protect cortical neurons from lipopolysaccharides(LPS)-induced neurotoxicity and the mechanisms responsible for this protective effect. METHODS After 7 d cultures，cultured cortical neurons were incubated with LPS 10 mg·L~(-1) for 4-24 h with or without other drugs. In co-incubation experiments, other drugs were added to the neurons 30 min or 1 h prior to incubation with LPS. The cell viability was assessed by MTT assay. The neuronal apoptosis was quantified by scoring the percentage of cells with apoptotic nuclear morphology after Hoechst 33258 staining. The cultured cells were then fixed on the 7th day and immunocytochemically stained with phosphorylated JNK1 antibody. The protein expressions of active caspase 3 and phosphorylated JNK1 were measured by Western blot. Nitric oxide (NO) generation was measured by Griess method. RESULTS The decrease of cell viability and the increase of apoptotic cells in cultured cortical neurons were observed incubated with LPS for 24 h compared with the normal controls. The cell viability of cortical neurons was decreased from (100.0±10.9)% in the normal control group to (72.3±2.1)% in the LPS-treated group and the apoptotic cell percentages were increased from (11.5±4.2)% in the normal control group to (39.5±8.2)% in the LPS group. LPS induced the increases in phospho-JNK1, active caspase 3 expression, and NO generation. Pioglitazone 0.01, 0.1 and 1 μmol·L~(-1), respectively inhibited LPS-induced decrease in cell viability and increase of apoptotic morphology, active caspase 3 expression in cultured neurons. In LPS+pioglitazone 1 μmol·L~(-1) group, cell viability was （97.8±9.7）%, the apoptotic cells percentage was (20.6±5.0)%, NO generation (6.8±1.3)μmol·L~(-1). Furthermore, pioglitazone also inhibited LPS-induced the increase in JNK1 phosphorylation and NO generation. JNK inhibitor SP600125 5 μmol·L~(-1) significantly inhibited LPS-induced neurotoxicity, cell viability was increased from (72.3±2.1)% to (109.8±11.8)%, the apoptotic cells percentage from (39.5±8.2)% decreased to (19.1±4.8)%, NO generation from （21.1±5.0）μmol·L~(-1) decreased to（4.0±1.3）μmol·L~(-1). The PPARγ antagonist GW9662 10 μmol·L~(-1) did not reverse the effects of pioglitazone. In LPS+pioglitazone 1 μmol·L~(-1)+GW9662 10 μmol·L~(-1) group, cell viability was (90.7±6.9)%, the apoptotic cells percentage was (23.4±4.1)%, and NO concentration was (5.8±0.7)μmol·L~(-1). CONCLUSION Pioglitazone protects cortical neurons against LPS insult at least via inhibiting JNK activity and NO generation, but not PPARγ activation.

Objective: To investigate the characteristics and prevalence of HIV infection among AIDS volunteer counseling and testing ( VCT ) clients in Shangcheng District, Hangzhou City from 2016 to 2019, so as to provide insights into local AIDS control. Methods: The demographic features, reasons for counseling and detection of anti-HIV antibody were captured from the VCT clinic of Shangcheng Center for Disease Control and Prevention from 2016 to 2019, and the reasons for counseling and prevalence of HIV infections were analyzed. Results: A total of 2 205 clients were included, among whom 1 920 participants ( 87.07% ) were male, 1 094 ( 49.61% ) were at ages of < 30 years, 1 293 ( 58.64% ) were single, and 1 165 ( 52.83% ) had an education level of diploma and above. The common reasons for counseling included a history of homosexual behaviors with men (887 clients, 40.23%), non-commercial irregular heterosexual behaviors ( 661 clients, 29.98% ), commercial heterosexual behaviors ( 308 clients, 13.97% ), HIV-positive spouse/regular sex partners ( 123 clients, 5.58% ), and no high-risk behaviors ( 47 clients, 2.13% ). The positive rate of anti-HIV antibody was 2.95% among the 2 205 clients, and a high positive rate was observed among clients at ages of 50 years and below ( 6.15% ), single clients ( 3.71% ), clients with an education level of primary school and below ( 6.04% ) and clients with HIV-positive spouse/regular sex partners ( 11.38% ). Conclusions Single men at ages of less than 30 years and with a high education level are predominant among VCT clients in Shangcheng District, and a history of homosexual behaviors with men is the predominant reason for counseling. There is a relative low prevalence rate of HIV infection among VCT clients in Shangcheng District; however, a high prevalence rate is found among single visitors at ages of 50 years and older, with an education level of primary school and below and HIV-positive spouse/regular sex partners.
