同侧肾缺血及对侧肾切除时留存肾DNA合成的研究

幼年小白鼠经体内~3H-TdR参入法液闪测定,检测一侧肾缺血及对侧肾切除后留存肾DNA合成的影响。结果表明:肾缺血、肾切除24h后均促进留存肾DNA合成。而一侧肾缺血同时对侧肾切除留存肾脏~3H-TdR参入量升高最明显。并探讨了一侧肾缺血及对肾切除后留存肾的代偿机理。     

阴道超声扫描对多囊卵巢综合征的诊断价值

对比２２例多囊卵巢综合征（ＰＣＯＳ）妇女经腹部及阴道超声扫描卵巢的声像图，以评价阴道超声对ＰＣＯＳ的诊断价值。结果表明：用阴道超声比腹部超声更易探及卵巢髓质回声异常及多囊改变（卵巢髓质回声异常分别为６８．１％及９．１％，Ｐ＜０．０１）；多囊改变分别为７７．３％及４０．９％，Ｐ＜０．０５）。提示使用阴道超声诊断ＰＣＯＳ其敏感性及准确性明显优于腹部超声。     

EFFECT OF ROSIGLITAZONE AND METFORMIN ON CLOMIPHENE CITRATE RESISTANCE IN WOMEN WITH POLYCYSTIC OVARY SYNDROME

Objective To evaluate the impacts of rosiglitazone and metformin on ovarian response, hirsutism and insulin action in women with polycystic ovary syndrome (PCOS). Methods Ninety women resistant to clomiphene citrate with PCOS were randomized, 40 cases to rosiglitazone group, 50 cases to meformin group. Rosiglitazone and metformon were administered for 6 months in combination with clomiphene citrate on cycle day 5th to 9th, respectively. The clinical evaluations were performed monthly. Reproductive hormone, serum glucose and insulin levels were observed before and after treatment. The data were analyzed using repeated analysis of variance (ANOVA). Results There were significant changes in reducing hirsutism score, serum testosterone level, LH/FSH ratio, and restoration of ovarian ovulation after metformin or rosiglitazone administration respectively (P<0.05). Insulin sensitivity was more significantly improved in the rosiglitazone group than in metformin group (P<0.05) After treatment. Homa IR and Homa β were decreased from 1.54±0.34 to 0.83±0.38 and from 5.83±0.55 to 4.95±0.54 (P<0.05) in the rosiglitazone group. The body mass index(BMI) was decreased from 25.30±3.64 to 23.83±2.32 in the metformon group (P<0.05). There were no significant changes in ovulation rate and pregnancy rate between groups (P>0.05). Conclusion Rosiglitazone can increase insulin sensitivity. Metformon may reduce BMI. They all restore regular menstrual cycles, increase pregnancy rate, and reduce testosterone and LH concentration in women with polycystic ovary syndrome.     

~(131)I—OIH肾图在双肾实质病变时的应用

本文对61例受检者~(131)I-OIH肾图及有关肾功能检查结果进行综合分析,试图探讨~(131)I-OIH肾图在双肾实质病变时的价值。结果表明:血、尿β-MG均和肾脏指数相关(n=20 γ_血=0.5125 γ_尿=-0.61624),尿β_2-MG和15min残留率相关(n=20,γ=0.6020)。正常人(n=19)与肾病综合症Ⅱ型(n=6),正常人与慢性肾盂肾炎(n=5)间,肾病综合症Ⅰ(n=5)、Ⅱ型间及急(n=5)、慢性肾盂肾炎间肾脏指数存在差异,15min残留率存在显著性差异。不同肾功能组间肾脏指数存在显著性差异。这说明:肾脏指数可以反映肾小管、肾小球的功能,而15min残留率主要反映肾小管功能。

PCR技术对两个Huntington舞蹈病家系的遗传学分析

本文对两个Ｈｕｎｔｉｎｇｔｏｎ舞蹈病家系进行调查并应用ＰＣＲ技术作了基因检测，所用引物５’－ＣＴ－ＧＴＧＧＧＡＣＣＴＣＧＧＣＴＡＡＧＣ－３‘及５’－ＧＴＣＡＧＣＡＣＣＴＣＡＧＡＣＣＡＧＡＧ－３‘，合成了ＰＹＮＺ－３２标志基因，经多态性连锁分析提示它对国人Ｈｕｎｔｉｎｇｔｏｎ舞蹈病进行基因检测和临床应用具有可能性。
