Objective To investigate the effects of C-terminal fragment of parathyroid hormonerelated protein (PTHrP107-139) on bone mineral density (BMD), bone histomorphometry and biomechanical properties in ovariectomized (OVX) rats and its effect on bone metabolism is also explored. Methods Forty 4-month old female Wistar rats in which 30 were ovariectomized and then divided into 3 groups: the placebo, the PTHrPC and the CT groups, the other 10 rats were Sham-operated as the control group (Sham). Five weeks later, the rats of PTHrPC and CT groups were subcutaneously injected with PTHrP107-139 (40 μg/kg) and Salmon Calcitonin (15 U/kg) respectively once every other day. The rats of the placebo and sham groups were injected with 0.2 ml saline once every other day. After treatment of 12 weeks, all rats were sacrificed and all samples were collected and analyzed. Results ① Compared with the placebo, the BMD and bone strength of PTHrPC and CT groups were significantly increased (P<0.05). ② Histomorphometry revealed that the tetracycline labeled bone surfaces, osteoid surfaces, mineral apposition rate and bone resorption rate were remarkably decreased in PTHrPC, and CT groups comparing with those of the placebo group. Conclusion Cter-minal PTHrP107-139 is effective in increasing the BMD, bone strength and quality when administered intermittently to ovariectomy-induced osteoporotic rats. Its increasing in bone quality may relate to reducing bone turnover and inhibiting resorption.

Objective To investigate the therapeutic effects of human parathyroid hormone related protein (PTHrP1-34) on osteoporosis of ovariectomized osteoporotic rats. Methods Sixty 4-month-old female Wislar rats were involved in this study and 40 of them were ovariectomized and another 20 received sham operation. After 6 weeks of ovariectomy the osteoporosis model was confirmed by examing 10 ovariectomized and sham-operated rats. The 30 osteoporotic rats were randomly divided into 3 treatment groups, i.e. PTHrP, estradiol and placebo. Human 40 ?g/kg PTHrP1-34 was subcutaneously injected once daily to PTHrP group and the estradiol group was injected with 40 ?g/kg estradiol benzoate once every 3 days.The placebo and shamoperated rats were given 0.2 ml saline every 3 days. The bone mineral density (BMD), bone histomorphology, the bone weight of dry and ash and serum Ca,P,alkaline phosphatase (ALP) were measured after 3 months' therapy. Results After 6 weeks of ovariectomy, the lumbar BMD of ovariectomized rats were significantly declined compared with those of the sham-operated rats. After 12 weeks treatment the femoral and lumbar BMD and the rate of bone weight of dry and ash in the PTHrP group were increased obviously compared with those of placebo groups.There was no significant difference between PTHrP group and estradiol group, in PTHrP group the percent age of trabecular area,trabecular width,osteoblast surface and mineral apposition rate were obviously higher than those in placebo group.Conclusion Treatment with 40 ?g/kg dose of hPTHrP1-34 administered once daily is effective in treating ovariectomy-induced osteoporosis.

Objective To observe multiple metabolic changes within one year after Roux-en-Y gastric bypass (RYGB) surgery in obese patients with type 2 diabetes mellitus, and to evaluate the index of the gastric bypass surgery and the determination of applicable population. Methods The clinical and laboratory data before and after surgery in 112 patients diagnosed as type 2 diabetes mellitus by RYGB were included in this study. According to BMI, these patients were divided into two groups: normal group (≤ 25kg/m2), and the overweight group (> 25 kg/m2). The physiologic and biochemical indexes of the patients were followed up at 1, 3, 6, 12 months, respectively. The statistical analysis was performed by SPSS17.0 software. Results Compared with the preoperative period, the levels of HbA1c and HOMA-IR in the postoperative period were significantly increased in the two groups. Principal component analysis showed that the postoperatively contributions of BMI and HbA1c in 6 months was bigger than that of the other indexes, while HOMA-β, HOMA-IR had larger contributions after 6-month postoperative period. Conclusion Various metabolic indexes in patients with type 2 diabetes improve significantly within one year after surgery, and the complete remission rate is gradually increased. The indexes including weight, blood glucose, serum lipids, HOMA-βand HOMA-IR in overweight and obese group have more significant improvements than those in normal group. Obese patients are more appropriate for the surgical treatment. The indexes, such as BMI, HbA1c,HOMA-βand HOMA-IR, should help to evaluate the operating effectiveness and preoperative indications.

Objective To study the expression of thymic stromal lymphopoietin(TSLP) and the activation of DCs in OVA-induced murine asthma model, and investigate the effects and underlying mecha-nisms of TSLP on lung inflammation. Methods Thirty BALB/c mice were randomly divided into control group, OVA group and TSLP neutralizing antibody treated group. The asthma model was evaluated by airway responsiveness and histological analysis of lung tissues ; The levels of TSLP mRNA in lungs were determined by quantitative real-time PCR; The expression of TSLP in lungs were determined by immunohistochemistry and Western blot; The expression of CD40, CD80, CD86 in BALF was detected by FACS. Results Both the histological analysis of lung tissues and the airway responsiveness were all consistent with the characteris-tic of murine asthma model. The expression of TSLP and TSLP mRNA in the OVA group was significantly in-creased compared with blank group. The expression of CD40, CD80, CD86 in BALF from OVA group was increased significantly compared with the control group. Furthermore, treating mice with TSLP neutralizing antibody reduced the expression of CD40, CD80, CD86 on dendritic cells, and IL-4, IL-5, IL-13 in the OVA group. Conclusion Our study indicate that TSLP was highly expressed in the bronchial epithelia of murine asthma model, via upregulation of CD40, CD80, CD86, induce DCs to active CD4~+ T cells and pro-duce type 2 responses, so that aggravating the lung inflammation of asthma. Blocking TSLP is capable of in-hibiting the production of Th2 cytokines, thus presents a promising strategy for the treatment of asthma.

OBJECTIVEThis study examined the changes of serum levels of interleukin 12 ( IL-12), transforming growth factor beta 1 (TGFbeta 1) and immunoglobulin E ( IgE) in children with asthma as well as the correlation of IL-12 and TGFbeta 1 with IgE in order to investigate their roles in asthma.

METHODSSerum levels of IL-12 , TGFbeta 1 and IgE were detected using ELISA in 85 asthmatic children at the acute and the remission stages. Thirty healthy children served as control group.

RESULTSCompared with the control group, serum IL-12 and TGFbeta 1 levels were significantly lower and serum IgE levels were significantly higher in the asthmatic group through the acute to the remission stages. Serum IL-12 and TGFbeta 1 levels (40.42+/-15.26 ng/L and 65.41+/-22.38 pg/mL) significantly increased in the asthmatic group at the remission stage compared with those at the acute stage (28.42+/-10.73 ng/L and 40.25+/-11.73 pg/mL) (P<0.01), but remained lower levels than those in the control group (67.42+/-20.58 ng/L and 178.54+/-90.56 pg/mL) (P<0.01). The asthmatic patients at the remission stage showed significantly decreased serum IgE levels (145.67 +/-51.25 IU/mL) compared with those at the acute stage (280.35 +/-80.54 IU/mL) (P<0.01), but the IgE level in the remission stage was obviously higher than in the control group (53.61+/-13.32 IU/mL) (P<0.01). Serum IL-12 and TGFbeta 1 levels were negatively correlated with serum IgE level in asthmatic children.

CONCLUSIONSThere might be an imbalance in serum IL-12, TGFbeta 1 and IgE levels in asthmatic children. IL-12, TGFbeta 1 and IgE may play an important role in the pathogenesis of asthma. They may be useful in the diagnosis and severity evaluation of asthma.
