盐酸恩丹西酮预防化疗所致呕吐Ⅱ期临床研究

观察国产５－ＨＴ３阻滞剂－盐酸恩丹西酮预防化疗所致呕吐的临床疗效。方法：采用随机自身交替对照方法分为两组观察，接受顺铂联合化疗组及非顺铂联合化疗组各２５例。盐酸恩丹西酮８ｍｇ，化疗前１５分钟静注，恩丹西酮８ｍｇ，化疗后８小时口吸口服。对照组：胃复安２０ｍｇ，化疗前１５分钟肌注，胃复安８ｍｇ化疗后８小时口服。     

β-内酰胺酶抑制短肽SIPIS04-01的表达、纯化与抑制作用测定

通过酵母双杂交系统从一个随机DNA片段文库中筛选到一个编码能与β-内酰胺酶结合的短肽SIPIS04—01的DNA序列，将它克隆到pGEX-4T-1的多克隆位点中，得到重组质粒pYG205。当用适量的IPTG诱导后，携带pYG205的E．coli DH5α能表达短肽SIPIS04-01-GST融合蛋白。利用谷胱甘肽Sepharose 4B亲和层析介质分离纯化短肽SIPIS04-01-GST融合蛋白，经凝血酶切割并分离纯化后，体外试验表明短肽SIPIS04-01具有抑制β-内酰胺酶的作用。     

乡镇卫生院生存状况

长期以来，由于各地卫生部门的重视程度不够，乡、镇医疗机构职工人心涣散，机构业务极度萎缩，经济效益低下，连年亏损甚至濒临倒闭。透视乡镇卫生院面临的生存困难，我们不难发现，出现这种局面的原因是多方面的。

Association between TGF-Beta1 in allograft and chronic allograft nephropathy]

OBJECTIVE: To investigate the relation between TGF-beta1 in allograft and chronic allograft nephropathy (CAN). METHODS: The levels of urine TGF-beta1 were tested in 146 recipients whose renal function were normal from September 1, 2000 to January 31, 2001. Twenty recipients with the highest level of urine TGF-beta1 were classified in group A, while 20 other recipients with the lowest level of urine TGF-beta1 were classified in group B. In these two groups biopsies were carried out in 14 cases and 12 cases respectively, and TGF-beta1 mRNA in the biopsies was measured by RT-PCR. The levels of TGF-beta1 in the blood were also measured in the two groups. Three years later, the renal function was compared between the two groups. Biopsies were carried out in renal recipients whose creatinine is higher than normal. RESULTS: The level of TGF-beta1 in the blood showed no significant difference between the two groups; 3 years after transplantation, the loss of renal function in group A was severer than that in group B. The number levels of CAN cases in group A was larger than that in group B. The expression levels of TGF-beta1 and TGF-beta1 mRNA of the allografts were higher in group A than in group B; there were statistically significant differences between the two groups. CONCLUSION: The findings suggest that there is an association between TGF-beta1 in kidneys and CAN. The level of urine TGF-beta1 after renal transplantation may predict future renal function.

动脉血气分析碱剩余在创伤救治中的研究进展

动脉血气分析碱剩余作为创伤早期评估和预后指标,可预测创伤患者的休克、复苏、输血、死亡率及重症监护室（Intensive Care Unit,ICU）入住率等,在儿科创伤、老年创伤和创伤骨科患者的评估中也仍然具有价值。随着急诊床旁即时检验（Point-of-care Testing,POCT）血气分析的发展,其结果也可快速获取。近年来动脉血气分析碱剩余值在创伤救治中已有一定的研究。本文将就动脉血气分析中碱剩余在各种创伤中的应用进行回顾总结,同时提出了碱剩余在未来临床应用中的展望。     

当归补血汤中不同组分对正常及血虚小鼠免疫功能的影响

目的：比较当归补血汤中的不同组分对正常及血虚小鼠模型的免疫调节作用。方法：采用MTT法测T、B淋巴细胞的增殖率;分光光度法检测脾细胞中抗体的生成;用乙酰苯肼和环磷酰胺制备小鼠血虚模型。结果：黄芪中的4个不同组分对正常小鼠均具有增强T、B淋巴细胞增殖率及促进抗体生成作用,而当归中的3个不同组分则作用各异,但是对血虚模型小鼠均表现出明显的免疫调节作用。体外实验发现：在2．5－250μg/mL浓度范围内,黄芪黄酮、黄芪皂苷以及黄芪和当归的挥发油部分均表现为良好的双向免疫调节作用,而黄芪和当归的多糖组分则为明显的浓度依赖性作用方式。结论：当归补血汤中的组分具有不同程度的免疫调节作用。
