GDM患者脂肪组织中HMGB1表达与产后糖代谢异常的关系

目的研究脂肪组织中高迁移率族蛋白B1(HMGB1)表达增加与妊娠期糖尿病(GDM)患者胰岛素抵抗程度及产后糖代谢异常的关系。方法选择2016年10月至2019年3月期间在海安市中医院诊断为GDM并接受剖宫产的126例患者作为GDM组,选择同期在该院接受剖宫产的健康孕妇150例作为对照组,检测剖宫产当天孕妇血清HMGB1、空腹胰岛素(FINS)的含量及脂肪组织中HMBG1、胰岛素受体底物(IRS)-1、IRS-2的表达水平,计算胰岛素抵抗指数(HOMA-IR)。随访产后1年内糖代谢异常的发生情况并绘制K-M曲线。结果GDM组患者脂肪组织中HMGB1的表达水平、血清HMGB1含量及FINS、HOMA-IR水平明显高于对照组(t值分别为14.496、16.503、19.068、13.446,P<0.05),脂肪组织中IRS-1、IRS-2的表达水平明显低于对照组(t值分别为11.616、10.596,P<0.05);GDM组患者脂肪组织中HMGB-1的表达水平与血清HMGB1、FINS的含量及HOMA-IR的水平呈正相关(r值分别为0.405、0.358、0.405,P<0.05),与脂肪组织中IRS-1、IRS-2的表达水平呈负相关(r值分别为-0.278、0.255,P<0.05);经K-M曲线分析,与GDM组中脂肪组织HMGB1低表达患者比较,HMGB1高表达患者产后1年糖代谢异常累积发生率明显升高(χ^(2)=3.933,P<0.05)。结论GDM患者脂肪组织中HMGB1表达增加与胰岛素抵抗的加重、产后糖代谢异常的发生有关。     

纳催离和苯那普利治疗高血压合并糖尿病动态血压及微白蛋白尿的比较研究

探讨纳催离（吲哒帕胺）治疗高血压（HP）合并Ⅱ型糖尿病（NIDDM）病人降压效应及对微量白蛋白（mAlb)尿的影响,并与苯那普利（洛丁）的疗效相比较,对HP合并NIDDM病人46例给予催离以及44例给予苯那普利治疗6个月,进行用药前后24h动态血压（ABPM）及尿mAlb测定,结果显示：与对照组及自身对照相比,纳催离与苯那普利治疗后,ABPM指标及尿mAlb均显著改善（P＜0．05或P＜0．01）,而两药之间疗效对比无差异,上述结果提示,纳催离治疗HP合并NIDDM病人与苯那普利效果一样,明显降低血压的同时,还兼有降低mAlb的作用。     

多发伤的骨折内固定

目的：认识多发伤中骨折的主要特点,探讨内固定在救治中的意义。方法：回顾1994－08～1999－08间手术救治多发伤66例,对其161处骨折中的98处进行了“仿AO技术”有关方法内固定。结果：骨折均满意愈合;涉及骨折关节51个,功能恢复满意率为96．08％。结论：在多发伤中,骨折、合并伤与并发症远较“一般骨折”复杂、严重;有效固定骨折是一种重要的救命措施;内固定手术应争取在伤后24h进行,但如受条件制约,伤后1－3wk内手术也可获得满意效果;仿AO技术中的某些方法,如拉力螺钉、张力带钢丝及自动加压钢板等,用于内固定可使骨折获得卓有成效的稳定性。     

蠕变局部损伤开裂的有限元模型

建立了蠕变局部损伤法模型,并给出单元进入损伤态的判据和失效的临界拉伸应变条件,局部蠕变损伤理论的实质就是试样是多种不同蠕变性能材料的统一,并由蠕变应力再分布得到证实,应用有限元对双缺口圆试样作了蠕变局部损伤分析,启裂时间和断裂蠕变应变值均与实验结果相吻合。     

止泻颗粒剂治疗小儿消化不良性肠炎136例

运用止泻颗粒剂与思密达作对照治疗小儿消化不良性肠炎,治疗组136例,对照组80例,2组总有效率分别为95．5％,37．5％,疗效比较具有显著性差异,P＜0．01。     

IGF-1在成骨样细胞增殖中的作用及与钾离子通道的关系

目的 :研究胰岛素样生长因子 - 1(IGF - 1)促大鼠成骨样肉瘤细胞 (UMR10 6 )增殖作用及与钾离子通道活动的关系。方法 :采用磺基罗丹明 (SRB)染色法观察细胞增殖并用膜片钳技术记录细胞膜钾离子通道电流的变化。同时用3 H -TdR掺入测定DNA合成的改变。结果 :IGF - 1可以明显地促进UMR10 6细胞的增殖 ,且使3 H -TdR掺入率增加 93.5 7%。在含有生长因子IGF - 1(10 -8M)的培养液中培养 12h后 ,钾通道电流比对照有明显增加 ,而且用钾通道阻断剂后 ,3 H -TdR掺入率下降。结论 :IGF - 1可促进大鼠成骨样肉瘤的DNA合成和细胞增殖。且细胞膜钾通道的活动与此促增殖活动密切相关

Clinicopathological characteristics,prognosis, and chemosensitivity in patients with metastatic upper tract urothelial carcinoma

PurposeTo investigate the clinical characteristics, chemosensitivity, and outcome of metastatic upper tract urothelial carcinoma (UTUC).Patients and MethodsRecords of patients with metastatic UTUC since January 2005 were retrieved from a database that included clinical and survival data. Statistical analyses including survival and multivariate analyses of factors were respectively performed by the Kaplan-Meier method and Cox proportional hazard model.ResultsA total of 250 consecutive UTUC cases were evaluated. There were 56 patients (22.4%) with initially diagnosed stage IV disease. The most common metastatic sites were lung (39.6%), distant lymph nodes (39.2%), bone (19.6%), liver (18.0%), and adrenal gland (7.2%), respectively, and the local recurrence rate was 10.4%. Two hundred thirteen patients received first-line chemotherapy. The overall response rate was only 28.7% and the median progression-free survival time was only 5.0 months. The overall survival time of the cohort was 18.0 months. Multivariate analyses showed that initially diagnosed stage IV disease, number of metastatic organs ≥3, no response to chemotherapy and cycles of chemotherapy ≤2 were adverse prognosticators for overall survival.ConclusionUTUC presented to be more prone to metastasize than locally recur and thought to have low chemosensitivity. Stage IV disease at initial diagnosis, number of metastatic organs, response and cycles of chemotherapy were independent prognosticators for metastatic UTUC.
