1999至2001年广州地区临床常见肠杆菌科细菌耐药性监测结果分析

目的 了解临床分离常见肠杆菌科细菌的耐药性。方法 统一采用纸片扩散法进行实验，以美国NCCLS文件为判断标准，每次监测均有质控数据。结果 共有11家广州市三级甲等医院实验室参加耐药性监测，三年共统计临床常见肠杆菌科细菌3147株。结论 对肠杆菌科细菌，亚胺培南的耐药率最低，可考虑为临床首选药物，阿米卡星、头孢他啶耐药率相对较低，可选择用药。庆大霉素的耐药率有逐年下降的趋势，将来可能成为临床一线药。而磺胺甲噁唑／甲氧苄啶、四环素、萘啶酸等耐药率相对较高，应慎用。氨节西林的耐药率很高，应避免使用。     

小鼠胚泡着床相关基因的差减筛选

目的:筛选新的小鼠胚泡着床相关基因。方法:对孕4.5 d小鼠着床和非着床位点的子宫内膜组织进行PCR差减。获得了2个新的在小鼠胚泡着床位点高表达的EST(EST8和EST81)。结果:EST8在孕4.5 d小鼠着床位点、肝脏中表达较高,在非着床位点和卵巢中亦有微量表达。EST81主要在孕4.5 d小鼠子宫着床组织和卵巢中表达,其它各种组织中也有微量表达。用PCR方法获得了相应的全长。cDNA,长度分别为1665bp和1364bp。结论:用差减筛选获得的两种cDNA是孕小鼠着床相关基因,其功能有待进一步研究。     

TNF-α和IL-6对绒毛膜11β-羟基类固醇脱氢酶I型和前列腺素合成酶II型的调节

目的 :研究肿瘤坏死因子 (TNF α)、白细胞介素 6(IL 6)对胎膜糖皮质激素代谢酶 11β 羟基类固醇脱氢酶I型 (11β HSD1)和前列腺素合成酶II型 (PGHS 2 )的影响 ,以探讨细胞因子导致分娩启动的机制。方法 :利用薄层层析法 (TLC)和Westernblot杂交法分别从酶活性、蛋白表达水平 ,研究IL 6、TNF α对原代培养的人类绒毛膜细胞 11β HSD1及PGHS 2水平的影响。结果 :TNF α和IL 6对绒毛膜滋养层细胞 11β HSD1还原酶活性有促进作用 ,对绒毛膜细胞 11β HSD1和PGHS 2的蛋白表达均有上调作用。 结论 :IL 6、TNF α对胎膜 11β HSD1及PGHS 2的诱导作用可能是其导致分娩启动的机制之一     

不同剂量HCG对体外受精-胚胎移植的影响

目的 :比较使用不同剂量人绒毛膜促性腺激素 (HCG)对体外受精 /胞浆内单精子注射 (IVF/ICSI)的结局及对卵巢过度刺激综合征 (OHSS)发病率的影响。方法 :对在本所接受IVF/ICSI辅助生育的 2 6 2例采用GnRH a长方案促排卵的患者进行回顾性分析 ,按HCG用量分为A组 (HCG 5 0 0 0～ 6 0 0 0U)、B组 (HCG 80 0 0～ 10 0 0 0U)。结果 :两组临床妊娠率分别为 35 .94 %和 38.0 5 % (P >0 .0 5 ) ,OHSS发生率分别为 2 .34%和 4 .4 8% (P >0 .0 5 )。结论 :减少HCG用量后对IVF/ICSI的临床妊娠率无明显影响 ,且可以减少OHSS的发生。     

胃癌患者血清肝细胞生长因子的检测及意义

Objective To explore the clinical significance of serum HGF level changes in gastric cancer pa-tients. Methods 60 cases of patients who operatied and clinicopathological confirmed gastric cancer, were detected serum HGF level by enzyme linked immunosorbent assay(ELISA) .40 cases were administered radical gastrectomy,20 cases of patients who had distant metastasis and loss operative chance were detected 7 days and 3 months preopera-tive,postoperative serum HGF level respectively. At the same time 40 cases of chronic gastritis patients and 40 cases of healthy examination people were selected as control group. Results Serum HGF level in patients with gastric canc-er was significantly higher than that of chronic gastritis and normal controls(P <0. 01). The serum HGF level of pa-tients with tumor vascular invasion significantly increased(P <0. 05). The patients with lymph node metastasis,serum HGF level was significantly higher than that patients with no lymph node metastasis(P <0. 05). The serum HGF level of patients with liver metastasis was significantly higher than that patients with no liver metastasis(P <0. 05). The se-rum HGF level of gastric cancer patients whose maximum diameter of the tumor ≥3cm were significantly higher than that maximum diameter of the tumor <3cm(P<0. 05). According to TNM staging of gastric cancer,the serum HGF level of Ⅰ phase and Ⅱ phase patients were significantly lower than that Ⅲ phase and Ⅳ phase patients(P <0.05).The serum HGF level of gastric cancer patients had no significant correlation with sex ,age and histological type(P <0.05). The serum HGF level of 40 cases of patients who were 1 week after surgery were significantly decreased,the patients who were 3 months after surgery were more obvious(P <0. 05 and P <0. 001). Conclusion HGF may play an important role in gastric cancer occurrence and development. The detection of serum HGF level can become an im-portant index for monitoring the degree of gastric cancer and prognosis of patients.

EXPRESSION OF p16,CYCLIN D1 AND RB PROTEIN IN GASTRIC CARCINOMA AND PREMALIGNANT LESIONS

Gastric carcinoma is one of the most serious diseases in mankind. Its pathogenesis has not been understood very clearly. Recent researches suggested that oncogenes (such as cyclin D1), antioncogenes (ie., p16, Rb) and cell cycle played an important role in the pathogenesis of gastric carcinoma. But there are few reports about the relationship between these genes in gastric carcinoma and gastric premalignant lesions. In this study, we will discuss these problems. MATERIALS AND METHO…
