目的 探讨糖尿病胃轻瘫大鼠不同血糖水平对Cajal间质细胞(ICC)的影响及其机制。方法 选择雌性Wista大鼠60只进行随机分组,实验组40只,对照组20只。实验组糖尿病Wista大鼠模型以单次腹腔注射链脲佐菌素法诱导。免疫组织化学荧光染色检测不同血糖浓度大鼠胃ICC数量及网络结构。结果 实验组大鼠血糖浓度高于对照组,ICC数量,低于对照组,且比较差异有统计学意义(P<0.05)。实验组大鼠中血糖浓度越高,ICC数量越低,说明血糖浓度升高可能与平滑肌及神经末梢之间缝隙连接的减少及其ICC网络的超微结构损伤及异常有关。结论 DM小鼠胃组织中血糖水平的升高,可能是DM胃中ICC数量减少的原因;外源性降低血糖能改善DM相关的胃肠道ICC病变。

Objective To observe the effects of glucose fluctuations on Cajal interstitial cells (ICC) of rats with diabetic gastroparesis(DGP) and its mechanistic. Methods 60 Wistar rats were selected and randomly divided into two groups. 20 rats in experimental group and 40 rats in control group. Used immunofluorescence staining to detect the amount of gastric ICC and network structure in DGP rats with different glucose levels. Results The blood glucose concentration in the experimental group was significantly higher than that in the control group, the amount of ICC in the experimental group was significantly lower than that in the control group(P<0.05). The amount of ICC decreased with the increase of glucose levels. In the experimental group, The gap junctions between smooth muscle and nerve endings, ultrastructural damage and abnormalities of the ICC network were probably related to glucose level. Conclusion The increase of glucose level was probably the cause of the decrease of the amount in ICC. Exogenousy decrease glucose levels probably can help to improve the lesion of ICC with DGP.

Objective To analyze the recurrence risk factors of aged patients with minor ischemic stroke under standardized secondary prevention. Methods Patients over 80 years old and with minor ischemic stroke history were enrolled, and the following data were collected: demographic characteristics, medical history, current medicine, blood test, imaging findings and recurrence of ischemic strokes. Patients were divided into two groups: the recurrence group and the non-recurrence group. Chi-square test,logistic regression models were performed to assess correlations between baseline variables and recurrence of minor stroke events. Results In our study, 26 patients had recurrent minor ischemic stroke(32.5%). The prevalence of recurrence of minor stroke was positively correlated with hypertension(CI 0.265, P 0.018), SBP(CI 0.232,P 0.038), d-2-dimer(CI 0.232,P 0.048). Patients in recurrence group are more likely to presented with SBP elevation compared to non-recurrence group(χ²=6.919, P=0.031). Unconditional logistic regression analysis showed that hypertension, especially high SBP significantly related to minor ischemic stroke recurrence. Conclusion Hypertension,especially elevated SBP, were considered as an independent risk factors for aged old patients with minor ischemic stroke who received standardized secondary prevention.

Objective To study the effects of PF induced chemotherapy combined with intensity modulated radiation therapy and two-dimensional radiotherapy on the short and long term curative effects in nasopharyngeal carcinoma. Methods The treatment condition of 101 cases of patients with nasopharyngeal carcinoma who were treated in the Tumor Hospital Affiliated to San Yat-sen University between January and December 2008 were retrospectively analyzed. According to different treatments, the cases were divided into the intensity modulated group and the two-dimensional group. The clinical curative effects, short-term toxic and side effects and survival status were compared between the two groups. Results At the end of radiotherapy, the total remission rate in the intensity modulated group was 92.86% while in the two-dimensional group was 77.97% (P<0.05). In the intensity modulated group, the incidence rates of grade Ⅲ-Ⅳgastrointestinal tract reactions (26.19%) and mucositis (14.29%) were significantly lower than those in the two-dimensional group (P<0.05). There was no significant difference in long-term side effects and survival rate between the two groups (P>0.05). Conclusion PF induced chemotherapy combined with intensity modulated radiation therapy in the treatment of patients with nasopharyngeal carcinoma has good short and long-term curative effects and few toxic and side effects.

Objective This study aimed to investigate the autophagy activators and inhibitors effects in nasopharyngeal CNE2 cells radiotherapy sensitization. Methods Atg5 gene silencing by RNA interference technology, two groups of cell autophagy inhibition were built by rapamycin and chloroquine respectively. Then 5Gy x-ray irradiation of cells was taken every day, after 8 days in a row in each group of cell growth and setting a control group. The cell viability was clonaled colony formation by MTT method assay and cell cycle by flow cytometry analysis. Results The three cell group survival rate, colony-forming rate and survival after irradiation were significantly lower (P<0.05) than the control group. Detection of cell cycle in addition to control three other groups concentrated in the G0/G1 period.That of two other periods was relatively fewer than that of the G0/G1 period. Conclusion Autophagy inhibitors, activators and atg5 silence improved the radio-sensitization to CNE2. The autophagy activator group improving the sensitivity was better than the others.This study provided evidence to sensitive radiotherapy, explored a new promising radiosensitization ways.
