Whole CanA Gene Amplification of Helicobacter pylori and Its Fingerprinting by Restriction Fragment Length Polymorphism

To set up a method of amplification for the whole CagA gene of Helicobacter pylori and its fingerprinting by restriction fragment length polymorphism(RFLP),nested PCR was employed in combination with TD-PCR to amplify the gene and EcoRI and Hind Ⅲ were used to generate the RFLP fingerprinting.Target DNA fragments from 13 of 20 samples were successfully amplified and the relevant RFLP fingerprintings were obtained.It is concluded that the method can be used to amplify the whole CagA gene and CagA gene has apparent diversity of RFLP profile.     

输尿管回肠吻合术在可控性尿流改道中的应用

目的 评价输尿管回肠吻合术在可控性尿流改道术后抗返流及防止上尿路感染中的效果。方法 根治性膀胱切除术后行去带盲升结肠可控膀胱术和新膀胱术的患者10例，采用带回盲瓣的回肠段作为可控性膀胱的输入襻，双侧输尿管黏膜下隧道法与回肠吻合，随访观察患者术后输尿管返流及上尿路感染情况等。结果 10例手术顺利，术后随访6～36个月，均未发生输尿管返流或上尿路感染，1例发生单侧肾积水，为吻合口狭窄所致。结论 黏膜下隧道法输尿管回肠吻合术预防去带盲升结肠可控性尿流改道术后输尿管返流及上尿路感染效果良好。

~(123)I-MIBG心肌显像预测依那普利对扩张型心肌病患者治疗效果的临床价值

目的探讨123I-MIBG心肌显像在治疗前预测依那普利对扩张型心肌病(DCM)患者治疗效果的临床价值。方法对24例DCM患者于依那普利治疗前行早期(20min)及延迟(3h)123I-MIBG心肌显像,采用心/上纵隔(H/M)比和心脏放射性洗脱率(WR)作为相对半定量计数分析,与超声心功能参数进行对比。根据123I-MI-BG心肌显像延迟相的H/M分为3组延迟H/M≥1.7为组Ⅰ,1.5<延迟H/M<1.7为组Ⅱ,延迟H/M≤1.5为组Ⅲ。组Ⅰ和组Ⅱ在平均治疗4.5个月后重复以上检查。结果治疗前3组间超声心功能参数比较均无统计学差异。治疗后组Ⅰ的左室射血分数(LVEF)和左室收缩末径(LVDs)明显改善,早期H/M和延迟H/M均明显改善(P<0.05),而WR无明显变化。治疗后组Ⅱ的延迟H/M明显改善(P<0.05),而早期H/M和WR均无明显变化,心功能参数也无改善。组Ⅰ和组Ⅱ患者均能耐受依那普利治疗,而组Ⅲ患者均不能耐受依那普利治疗。结论123I-MIBG心肌显像在治疗前预测依那普利对DCM患者的治疗效果方面有一定价值。     

ALTERATION OF CHOLESTEROL SULFATE IN HUMAN SERA DURING THE COURSE OF PREGNANCY

Objective To determine the concentrations of cholesterol sulfate ( CS) in human sera and pla-cental villi during the course of pregnancy. And to analyze its inhibitory activity on thrombin and further characterize the functional significance of CS. Methods The concentrations of CS were determined by thin-layer chromatog-raphy (TLC) on 60 cases of normal pregnant women and 30 cases of normal placental villi. The effect of CS in human sera on the activity of thrombin was analyzed. Results The concentrations of CS in human sera gradually increased from the first to third trimester of gestation with a correlation coefficient of 0. 69, and a correlation between the concentration of CS and weeks of gestation (P <0. 01). CS was also contained in the placental villi, and its concentrations at the second and third trimester of gestations were 4. 7 and 6. 2-fold of that at the first trimester of gestation. CS inhibited the activity of thrombin. Conclusion Placental CS is one of the sources of CS in the serum , pr
