Clinical Experience in TCM Differential Treatment of Fatty Liver

In recent years, with improvement of living standard, changes in dietary structure and technical progress in medical tests, the rate of detecting fatty liver has been rising, hence constant increase in its incidence. Based on the TCM principle for differentiating syndromes, the authors have achieved remarkable curative effects in treating fatty liver. TCM Conception on Fatty Liver There is no fatty liver in the terms of TCM. However, according to its clinical manifestations, the disease may belong to the categories of “abdominal mass”, “mass at hypochondria”, “hypochondriac pain”, “accumulation of phlegm with stasis”. Its etiology and pathogenesis mainly lie in uncontrolled diet or     

拉米夫定阻断乙型肝炎病毒宫内传播的临床探讨

【目的】研究拉米夫定对HBsAg阳性孕妇的乙肝病毒 (HBV)宫内阻断作用。【方法】拉米夫定组 43例 ,孕 2 8周起口服拉米夫定 ,每天 10 0mg至产后 30d。对照组 5 2例 ,未予用药。两组孕妇均于孕 2 8周、分娩前 ,其新生儿于生后 2 4h内免疫接种前抽静脉血检测HBsAg、HBeAg及HBV的定量。【结果】拉米夫定组孕妇HBV的DNA水平显著下降 (P <0 0 5 ) ,其新生儿宫内感染率 (16 3% )明显低于对照组 (32 7% ) ,P <0 0 5。两组孕妇及其新生儿未发现有不良反应。【结论】携带HBV孕妇产前服用拉米夫定可有效减少HBV宫内感染发生率。     

生物化学与细胞生物学课程整合的探讨

为了适应新世纪教学内容和课程体系改革的要求,我校借鉴美国哈佛大学医学院的经验,将生物化学与细胞生物学两门课程整合为“细胞的化学与生物学”。整合后在减少两个学科间重复内容、增加学科间联系、减少学时、早期接触临床、培养学生分析解决问题的能力、创新能力等方面有了很大改进,为这两门课程的改革开辟了新途径。     

Organic anion transport in HepG2 cells: absence of the high-affinity, chloride-dependent transporter.

In previous studies, we identified a 55 kD organic anion-binding protein in liver cell sinusoidal plasma membrane subfractions. Other investigators identified another 55 kD bromosulfophthalein/bilirubin binding protein on the surface of rat hepatocytes and HepG2 cells and suggested that this protein served as a transporter for these ligands. In this study, transport of 35S-sulfobromophthalein by the human hepatoma cell line, HepG2, was quantified in the presence and absence of bovine serum albumin to further clarify the possible function of these plasma membrane binding proteins. In contrast to results in normal rat hepatocytes, virtually no uptake of 35S-sulfobromophthalein by HepG2 cells in the presence of bovine serum albumin was found. In the absence of albumin, HepG2 cells expressed temperature-dependent uptake of 35S-sulfobromophthalein. However, the high-affinity Cl(-)-dependent sulfobromophthalein transport that characterizes normal rat hepatocytes was absent, as indicated by an approximately 95-fold lower affinity and 170-fold higher capacity of HepG2 cells for sulfobromophthalein compared with previous results with rat hepatocytes. These results suggest that 55 kD sulfobromophthalein/bilirubin-binding protein on the liver cell surface differs from organic anion-binding protein and is not responsible for sulfobromophthalein extraction in the presence of albumin, although it may play some role in lower affinity transport by cells. Immunoblot analysis and metabolic labeling of HepG2 cells demonstrated synthesis of organic anion-binding protein. However, light microscopic immunocytochemistry and immunoprecipitation of surface iodinated rat hepatocytes and HepG2 cells with antibody to a recombinant organic anion-binding protein fusion protein indicated absence of organic anion-binding protein on the surface of HepG2 cells.(ABSTRACT TRUNCATED AT 250 WORDS)     

米非司酮配伍米索前列醇终止早孕用药方法的探讨

作者对１２０例妊娠４９ｄ以内的孕妇采用４种不同的服药方法进行药物流产，其中使用第３、４种用药方法的孕妇均于加用米索前列醇后８ｈ内排出孕囊，且２ｈ内排出率明显增加，与常规用药方法比较有显著性差异（Ｐ＜０．０１），同时对用药机理作了讨论。     

吸入一氧化氮对心瓣膜置换术后肺动脉高压患者血流动力学的影响

目的：观察吸入一氧化氮（ＮＯ）对心瓣膜置换术后肺动脉高压患者血流动力学的影响。方法：选择９例心瓣膜置换术后伴肺动脉高压的病人，吸入ＮＯ０．００３％，观察三个时象点：吸入ＮＯ前；开始吸入ＮＯ后１５分钟；停止吸入ＮＯ后１５分钟。结果：吸入ＮＯ能显著降低肺动脉压和肺循环阻力指数（Ｐ＜０．０１），停止吸入ＮＯ１５分钟后，肺动脉压和肺循环阻力指数恢复到原有水平。在整个观察过程中，心率、平均动脉压、中心静脉压、肺动脉楔压、体循环阻力指数和心脏指数均无显著变化（Ｐ＞０．０５）。结论：吸入ＮＯ具有选择性肺血管扩张作用，是治疗心瓣膜置换术后肺动脉高压的较理想药物。     

Partial mastectomy with axillary lymph node dissection and radiotherapy as a new treatment modality of breast cancer (I).

This is the first preliminary report among two consecutive papers. Partial mastectomy(PM), axillary lymph node dissection(AD) and radiotherapy (RT) were performed on seventeen operable breast cancer patients who had been admitted from April 1991 to March 1992 to the department of surgery, Yongdong Severance Hospital for improved cosmetic appearance and better survival rate. Of seventeen patients, 47% were T1 lesion and 76% were stage I and II. Extensive intraductal component(EIC) within or around the tumor was also analyzed. Twenty nine per cent of the patients were EIC positive. The mean number of axillary lymph nodes was 21.5 after PM with AD and 20.5 after mastectomy. For radiotherapy, 4,500 rad was delivered to the breast parenchyma and 1,600 rad of boost to the primary tumor site using the electron beam method after surgery. All patients have since been living well without any local recurrence and were satisfied with breast preservation for the one-year follow-up period. We concluded that the PM, AD and RT can be another surgical treatment modality of breast cancer. A longer follow-up data will be followed on the second paper.
