Dynamic observations on NK cell activity and IL-2 and IFNγ productionin vitro in patients on maintenance hemodialysis

Summary In order to study the immune function of patients on maintenance hemodialysis (MHD), we assayed NK cell cytotoxicity against K⁵⁶² targets in 40 patients on MHD, and the production of IL-2 and IFN in peripheral blood mononuclear cells (PBMC) after PHA stimulation, in contrast to those in normal controls. The results showed that NK cell activity and IL-2 and IFN levels were markedly lower in the patients than in the controls. Afeter a single dialysis, NK cell activity as well as IL-2 and IFN levels were elevated to different extent. But there was no significant change in patients after long-term dialysis. There was a positive correlation between the NK cell activity and IL-2 and IFN activity in the controls, but no such correlation was found in the patients on MHD. There was a positive correlation between the NK cell activity and IL-2 activity in patients after dialysis, suggesting that immune function were impaired in the patients on MHD, with a decline in the activity of NK cell and IL-2 and IFN, and a disorder of immune regulation cycle. These abnormal immune impairments in the patients could be partly corrected by hemodialysis. However, long-term hemodialysis is not much helpful in the improvement of patient’s immune function.     

健康教育项目设计PRECEDE诊断评价模式

美国著名健康教育专家Lawrence W.Green 提出的健康教育项目设计PRECEDE 诊断评价模式,站在社会健康的宏观高度,全面规划健康教育内容、方式与作用环节,并从项目设计开始就将监测评价纳入项目内容。由于设计思维的缜密与方法的科学性,保证了健康教育项目能够紧紧抓住重点健康问题,做到有的放矢。因此,在模式的引进和使用过程中,应结合我国妇幼卫生的现状和当地的实际情况,设计出适合我国国情的妇幼卫生健康教育项目规划,为发展我国妇幼卫生事业服务。     

肝炎和肝硬化患者胆囊超声改变的观察与分析

目的 :研究肝炎肝硬化患者胆囊彩色B超声像图变化 ,并探讨其临床意义。方法 :采用彩色超声诊断仪对 139例肝炎和肝硬化患者及 4 2例非肝炎体检者进行胆囊超声检查。结果 :慢性肝炎、重型肝炎、肝硬化患者组与非肝炎对照组彩色B超胆囊异常率比较均差异显著 (P <0 .0 1)。重型肝炎、肝硬化组与慢性肝炎组之间胆囊异常率也存在明显的差异 (P <0 .0 5 )。结论 :慢性肝病患者胆囊异常与胆囊本身炎症无关。胆囊声像图的改变对判断肝脏实质性病变的严重程度及指导临床治疗有一定的参考价值。     

7β-(6-取代-2-喹诺酮-3-乙酰氨基)头孢菌素的合成

以6-取代-2-喹诺酮-3-乙酸为侧链,用CDI法和潘化酯法与7-ADCA,7-ACA,7-ACT,和7-ACD缩合,合成了16个新的7β-(6-取代-2-喹诺酮-3-乙酰氨基)头孢菌素类化合物,通过溶媒转提,葡聚糖凝胶(Sephadex LH-20)柱层析及离心薄层层析分离精制,得到纯品。初步体外抑菌试验表明:新化合物对革兰氏阳性及某些阴性菌具有高度敏感性。大多数化合物对所试试验菌的抗菌活性与头孢唑啉和青霉素G钠相当,有些比它们还强。     

Optimizing Suicide Gene Therapy for Head and Neck Cancer

An effective “suicide gene” therapy strategy in experimental studies has been the use of the herpes simplex virus thymidine kinase gene(HSV-tk) to sensitize tumors to the cytotoxic effects of ganciclovir administration. Previous studies using this model have focused on utilizing maximal viral titers and high levels of ganciclovir that are not compatible with human dosing. Because of the high ganciclovir doses and the maximal viral titers, this strategy has limited application to actual clinical scenarios. In the following studies the authors investigate tumor regression in an oral squamous cell carcinoma animal model as a function of variable adenoviral titers and more physiologic ganciclovir dosing. Using adenoviral titers ranging from 1 × 10⁸ to 2 × 10⁹ plaque forming units(pfu) to treat oral tumors, they found no statistical difference in tumor regression among the different viral doses, despite differences in mitotic activity. Each treatment group, however, demonstrated a significant effect on tumor regression when compared with controls. Furthermore, the authors were able to reduce the level of ganciclovir administration to 10 mg/kg twice daily from established levels of 100 to 150 mg/kg twice daily while maintaining significant tumor responses to the HSV-tk therapy. Mean survival of animals treated with this lower ganciclovir dose was significantly higher than in controls and was equal to established means based on previous studies using higher ganciclovir doses. The optimization of this suicide gene therapy strategy is imperative in order to minimize theoretical and known viral and ganciclovir toxicities while establishing a foundation upon which to design appropriate and effective clinical trials.
