Objective To investigate the effect of pancreatic ? cell dysfunction on abnormal glucose tolerance during Graves hyperthyroidism. Methods We investigated 6 healthy people and 36 Graves disease patients with abnormal glucose tolerance, and determined blood sugar and insulin at 0, 60 and 120 minutes after breakfast respectively. Then the HOMA-IR, HOMA-? and ISI were compared between the two groups. Results The HOMA-IR in the Graves disease patients with abnormal glucose tolerance is evidently higher than in the healthy subjects (P

Objective To elucidate the function and regulatory mechanism of LyGDI involved delayed cell death in the human K562 cells and HL-60 cells induced by 60Co γ-rays. Methods Erythrosine B cells staining was used to count the apoptosis rate. PI staining and flow cytometry were applied to check the cell cycle. The expression of LYGDI and Rac1 was resolved by Western blot by using monoclonal antibody of LyGDI and Racl. The distribution of Racl protein in cells was observed with immunofluorescence by using the confocal microscope. Results The K562 cells showed G2/M phase arrest and the percent age was 71.3%. The apoptosis rate was very low at early post-irradiation stage in the K562 cells. The apoptosis rate was 14% in the K562 cells at 24 h post-irradiation with 8 Gy of γ-rays, and delayed cell apoptosis was present. LyGDI was cleaved in the K562 cells irradiated by 4 Gy 60 Co γ-rays after 24 hours post-irradiation. The expression of Racl protein was not altered at all, but the distribution was changed in the irradiated cells while the Racl protein moved to cell membrane and a little in cell nucleus. The Racl was activated with the losing the binding affinity with the LyGDI. Conclusion LyGDI could promote the delayed cell apoptosis, which is through the activation of the Rac1.

Objective To evaluate the efficacy of intensity-madulated radiotherapy(IMRT) as the primary treatment in nasopharyngeal carcinoma (NPC). Methods Between November 2001 and March 2006,147 newly diagnosed NPC patients were treated with IMRT. The disease was Stage I in 3 patients, Stage Ⅱ in 35,Stage Ⅲ in 67 and Stage Ⅳ in 42. For T1-2 disease,the prescription dose was 70 Gy to the gross tumor volume( GTVnx) and positive neck nodes ,60 Gy to the planning target volume I, and 50-56 Gy to the clinically negative neck. For T3-4 disease,the prescription dose was 74-78 Gy to GTVnx. The local control rate(LC),overall survival (OS), disease-free survival (DFS) and distant metastasis-free survival (DMFS) were estimated by Kaplan-Meier method. Results The 3-year LC, OS, DFS and DMFS of the whole group were 93.2% ,93.5% ,72.6% and 74.4% ,respectively. T stage was a significant predictor of LC and OS. For patients with T1-2 and T3-4 disease,the LC was 100% and 86.9% (P=0.007) and OS was 95.5% and 91.3% (P=0.030), respectively. N stage was a significant predictor of OS, DFS and DMFS(P=0.03,0.004 and 0.0004,respectively). The grade Ⅰ+ Ⅱ and Ⅲ acute toxieities of parotid were 96.6% and 1.4%. The rate of grade Ⅱ xerostomia at 3-month, 6-month, 1-year and 2-year after radiotherapy were 43.0%, 12.0% ,4.9% and 3.2%. Conclusions The treatment results are promising according to our target definition and dose prescription protocol for nasopharyngeal carcinoma.

Expressions of interleukin-6 (IL-6) and its receptor (gp80、gp130) in 8 patients with Graves' disease (GD) were compared with those in 8 euthyroid patients with nodular goiter or benign thyroid adenoma. The thyroid tissues of GD expressed significantly higher IL-6 mRNA, gp130 mRNA and IL-6 protein than those of the control group, suggesting that activated IL-6/gp130 signal pathway in the thyroid tissue may contribute to the pathogenesis of GD.

Objective To study the effects of rhubarb on the mitogen-activated protein kinase (MAPK) sig-naling transducfon pathway in rats with severe acute pancreatitis (SAP),and to investigate the treatment mecha-nism of rhubarb on SAP. Method One hundred SD rats were provided by from the Animal Center of Nanjing Uni-versity. All animals were randomly divided into sham operation (n=33), SAP (n=33) and rhubarb groups (n=34). SAP model was induced by retrograde injection of 5% sodittm taurocholate. Rhubarb was given with 10% rhubarb decoction (2 mi/100 g) at the time of pancreafitis induction in the rhubarb groups. At 1, 3, 6, and 12 h after the models were established,animals were killed. MAPK activity in pancreatic tissue was examined by West-em blotting and the mRNA levels of TNF-α and IL-6 in pancreatic tissues were detected by RT-PCR. All data were analyzed by SPSS statistical software and statistical differences between values from two sroups were determined by the Student's t -test. Results MAPK activity, TNF-α and IL-6 mRNA levels in pancreatic tissues were signifi-cantly enhanced in the SAP group compared with the sham operation group (all P<0.01). Rhubarb treatment markedlyinhibited MAPK activation,TNF-α,IL 6 mRNA (all p<0.01). Conclusions Rhubarb can alleviate the inflammatory response of SAP by down-regulating MAPK activity.
