BIOEQUIVALENCE BETWEEN rhGH FOR RECONSTITUTION AND READY-TO-USE rhGH IN TWO LIQUID FORMULATIONS

Objective To evaluate the bioequivalence between recombinant human growth hormone （rhGH） for reconstitution, and two dosages of liquid formulation of rhGH [ （151U） 5mg or （301U） lOmg per 3ml ]. Methods The study drugs were tested in a randomized, single-blind and three-period crossover studies in 24 healthy male subjects. The three drugs were administered by subcutaneous injection at a dose of O. 21U/kg body weight. A continuous somatostatin infusion was given in order to suppress the secretion of endogenous GH. The ve- nous blood samples were drawn at different time points to test the serum concentration of GH. The pharmacokinetic parameters were analyzed by statistical methods. Results 90% confidence intervals （CI） of AUC0-24h among three products were all within 80% - 125% interval （ 103. 4% - 116. 5%, 105. 7% - 119. 6% and 91.9% - 103. 7%, respectively）, and the Cls of C,~ among three products were all within 70% - 143% interval （91.9% - 114. 0%, 103. 7% -127. 2% and 81.6% -97. 4%, respectively）. There was no statisitical difference of tmax among all the three products. Conclusion These data demonstrate that there is bioequivalence between rhGH for reconstitution and two liquid formulations of rhGH.

细胞移植治疗心肌梗死的研究与展望

细胞移植是治疗心肌梗死的一种新策略,本文对目前应用于临床研究的骨骼肌卫星细胞移植及骨髓干细胞移植治疗心肌梗死的进展进行综述。上述两种细胞移植均具有来源丰富、无排斥反应的特点,而且通过研究观察表明,上述两种细胞移植后,心脏功能均能得到改善,故具有美好发展前景。但二者亦均具有不足之处和需要解决的问题,还需进一步研究与探索。

目的总结钻颅碎吸治疗高血压性脑出血的疗效。方法利用配对方法与保守治疗病人进行对比。碎吸组反复穿刺血肿,调整血压。对照组采取降颅压,营养脑细胞等内科治疗。结果碎吸组病死率15.6%,对照组病死率27%,两组相比P<0.05,CT观察发现,碎吸治疗可加速血肿的吸收。半年后随访结果表明,碎吸治疗可降低致残率。结论钻颅碎吸术可作为治疗部分高血压性脑出血病人的理想选择。     

Comparison of clinical outcomes of frozen-thawed blastocysts transfer in natural and hormonally controlled cycles

Objectives:To assess the clinical outcomes of frozen-thawed blastocysts transfer in natural and hormonally controlled cycles.Methods:A retrospective analysis of natural and hormonally controlled cycle for 246 frozen-thawed blastocyst transfer cycles,the clinical pregnancy rate,implantation rate,early abortion rate were compared.Results:Of the 192 hormonally controlled cycles,the cancel rate,clinical pregnancy rate per ET,implantation rate and abortion rate were 7.3%(14/192),53.9%(96/178),38.8%(131/338)and 11.5%(11/96)respectively,whereas in 54 natural cycles,these rates were 16.7%(9/54),68.9%(31/45),52.9%(45/85)and 16.1%(5/31)respectively.There was no significant difference between the two groups with regard to the clinical pregnancy and abortion rate per ET,but the cancel rate and implantation rate were higher in natural cycles.However,the pregnancy and implantation rates of patients without PCOS in hormonal control cycles(57.2%,40.9%)were similar with those in natural cycles(P>0.05).Conclusion:These findings suggested that both hormonally controlled and natural cycles had similar pregnancy outcomes in frozen-thawed blastocysts transfer.     

肝硬化患者的心理状态分析

目的:分析肝硬化患者的心理状态.方法:对40 例肝硬化患者(研究组)及40 例健康志愿者(正常对照组)采用汉密尔顿焦虑量表(HAMA)和汉密尔顿抑郁量表(HAMD)进行问卷调查及对比研究.结果:肝硬化患者的焦虑发生率为27.5%,抑郁发生率为42.5%,焦虑合并抑郁的发生率为27.5%,与正常对照组相比,肝硬化患者的焦虑抑郁不良情绪的发生率升高(P＜0.05),其中家庭月收入少于1 000元、有并发症的肝硬化患者的抑郁积分较高(P＜0.01).结论:肝硬化患者的焦虑、抑郁情绪发生率显著高于正常人群,且受家庭经济状况和有无并发症的影响.
