Objective To observe the efficacy of rosiglitazone treatment in impaired glucose tolerance (IGT) with hyperinsulinemia. Methods 56 IGT patients were divided into two groups randomly:control group (28 cases) and rosiglitazone group (28 cases). Improving life style were given to control group,while improving life style and rosiglitazone (4mg/d) were given to rosiglitazone group for 12 weeks. The body mass index (BMI),fasting and postprandial plasma glucose,insulin and insulin sensitivity index (ISI) were observed. Results In control group the fasting and postprandial plasma glucose and insulin showed no difference between pre-and post-treatment (P>0.05).The levels of the fasting and postprandial plasma glucose and insulin dropped obviously in rosiglitazone group compared to both the baseline levels and the levels of control group at 12 weeks of treatment(P<0.05). The BMI and body weight dropped obviously in control group at 12 weeks of treatment (all P<0.05),but showed no difference in rosiglitazone group (P>0.05). The ISI increased markedly in rosiglitazone group (P<0.05),but showed no difference in control group (P>0.05). Conclusions The rosiglitazone treatment increases insulin sensitivity obviously,improves first-phase insulin secretion,and postpones the progression to T2DM from impaired glucose tolerance in patients with IGT

Objective To investigate the role of serotonin transporter (SERT) in pathogenesis of abdominal pain in irritable bowel syndrome (IBS). Methods Neonatal SD rats were divided into control group and IBS abdominal pain model group which was established by colorectal distension.The colon, nucleus raphes dorsalis (NRD) and prefrontal cortex (FC) tissues were harvested when all rats grew into adults. Expressions of SERT and 5-HT were determined by real-time PCR and immunohistochemistry. Results The expression of SERT mRNA in colon, NRD and FC tissues in model and control group were 13.95±2.05 vs 8.65±1.33, 52.69±22.59 vs 13.82±5.71 and0.48±0.17 vs 0.17±0.14, respectively, with significant differences (all P values ＜0.05). The protein expression of SERT in colon and NRD,but not FC tissues,decreased in model group compared with control group (13.19±3.82 vs 21.35±4.49,2.47±0.44 vs 4.55±0.92, respectively, P＜0.05).Meanwhile, in comparison with control group, the expression of 5-HT in colon was significantly increased in model group (5.56±0.48 vs 2.68±0.22), but decreased in NRD and FC tissues (3.75±0.43 vs 7.46±0.72, 5.07 ± 0.80 vs 7.97 ±1.10, respectively, P＜0.05). Conclusions Low expression of SERT in brain and colon may attribute to the pathogenesis of abdominal pain in IBS.

Paraneoplastic pemphigus(PNP) is a clinically, histologically, and immunopathologically distinct autoimmune bullous disease characterized by severe painful mucosal erosions and polymorphous skin lesions. Histopathology shows acantholysis with lichenoid dermatitis or keratinocyte necrosis, and there are autoantibodies to various epidermal proteins with underlying neoplasia. We report two cases of paraneoplastic pemphigus in China firstly. The clinical, histologic, and immunopathologic findings of both cases strongly suggest the diagnosis of paraneoplastic pemphigus associated with Castleman′ s tumor.

The purpose of this study was to construct expression vectors of idiotype (Id) SmIg in patients with B-chronic lymphocytic leukemia and to express them in E.coli to obtain recombinant Id, and to investigate the effect of the protein on the proliferation and secretion of IL-2 and IFN-gamma of stimulated peripheral blood mononuclear cells (PBMC) in vitro. Light chain gene and Fd fragment of heavy chain gene were inserted into fd-tet-DOG2 vector to construct fd-tet-DOG2-Fab. Fab gene was further cloned into expression vector pHEN2 to construct the soluble expression vector pHEN2-Fab. After induction by IPTG, Fab protein was purified by Ni-NTA-chromatography. MTT was used to determine the effects of purified protein on the proliferation of stimulated PBMC in vitro and the concentrations of IL-2 and IFN-gamma in the culture supernatants were detected by ELISA. The results showed that recombinant pHEN2-Fab expression vector was constructed successfully. Fab protein was expressed in positive clone after induced by IPTG and two specific bands at 24-25 kD position were observed by SDS-PAGE electrophoresis. Proliferation of PBMC could be induced by purified Fab and the concentrations of IL-2 and IFN-gamma in culture supernatants were increased significantly after induction. It was suggested that the expression vector of SmIg Fab fragment was constructed successfully, and expressed and secreted from E. coli. The Fab protein could induce proliferation of PBMC and promote secretion of IL-2 and IFN-gamma.

Objective To evaluate the role of 18F fluorodeoxyglucose positron emission tomography computed tomography (PET-CT) in nasopharyngeal carcinoma (NPC) after radiotherapy. Methods A total of 27 NPC patients received 18FDG PET-CT 8-32 weeks after radiotherapy. All the patients were followed up for about 12 months after the examination. Metastasis and residual were evaluated by PET-CT. The correlation between SUV and prognosis was analyzed. Results Of these 27 patients, metastasis was found in 2 patients by PET-CT. Local persistence was diagnosed as for SUV≥2. 5 by PET-CT in 20 patients, among whom 18 were confirmed by biopsy and then received brachytherapy or conformal radiotherapy. One year local control and survival rates were 70% and 81%. Based on SUV, the patients were divided into group one for SUV between 2. 5 and 5(9 patients) or group two for SUV≥5 (11 patients). In group one and group two, the one year local control rate, survival rate and metastasis rate were 67% , 55% (P=0.670) , 64% ,89%(P=0.319), and 22% , 82% (P =0. 022) , respectively. Conclusions PET-CT is valuable for the identification of residual nasopharyngeal carcinoma. SUV of residual tumor is related to metastasis.
