AⅡ受体拮抗剂ACEI对慢性肾衰患者血浆ANF及RAS的影响

目的了解血管紧张素Ⅱ受体拮抗剂(ATRA)和转换酶抑制剂(ACEI)对慢性肾衰(CRF)高血压患者血浆心钠素(ANF)和肾素*.血管紧张素系统(RAS)的影响。方法受试者口服氯沙坦(Los组)或福辛普利(Fos组)连续12周，于治疗前和治疗后第4、8及12周测定坐位舒张压(SiDBP)、血清尿素氮(BUN)、血清肌酐(SCr)、ANF、血管紧张素Ⅰ(AⅠ)和血管紧张素Ⅱ(AⅡ)。用SPSS7.0软件作统计分析。结果经12周治疗，两组患者SiDBP均降至目标值。Fos组与治疗前比较，AⅡ下降，ANF和Scr升高(P<0.01)。Los组AⅡ明显升高(P<0.01)，ANF在短暂升高后降至治疗前水平，Scr无变化。结论ACEI可能对CRF高血压患者肾内灌注压有影响，ANF动态改变可作为肾内灌注压变化的指标之一。ATRA对肾内灌注压影响小于ACEI。     

带蚓状肌的游离足趾再造拇、手指

人外周血CD68^＋单核细胞体外的分选及诱导分化为破骨细胞

OBJECTIVE: To establish a method for obtaining highly purified primary human osteoclast precursors for the biochemical and molecular biological research. METHODS: CD68(+) mono/macrophages were separated from peripheral blood mononuclear cells (PBMCs) of healthy donors by means of immunomagnetic cell sorting for subsequent analysis with flow cytometry. The isolated cells were incubated on coverslips or bone slices in the presence of dexamethasone(10(-8) mol/L), macrophage colony-stimulating factor (25 microg/L ) and soluble receptor activator of nuclear factor (NF)-kappaB ligand (s-RANKL, 16 microg/L). Calcitonin receptor (CR) immunocytochemistry and tartrate-resistant acid phosphatase (TRAP) histochemistry were employed. The bone slices were also studied by scanning electron microscopy (SEM). RESULTS: Fluorescence-activated cytometric analysis showed that 93.06%+/-0.61% n=4 of the selected cells were CD68(+) cells. After 7 days of culture of the CD68(+) cells, VR+, TRAP+ multinucleated giant cells appeared, and resorption lacunae could be observed by SEM. CONCLUSION: Highly purified CD68(+) cells can be obtained from human PBMCs as the osteoclast precursors, and mature osteoclasts can be induced from CD68(+) mono/macrophages by RANKL.     

太太,十年打造金字招牌

一个企业风光几年,在全世界都是一种普遍现象。在日本曾经做过统计,经营历史超过5年的企业不到20%,80%都在5年内消失了。然而创建于1992年12月18日的深圳太太药业股份有限公司,虽然是以保健品起家,多年来却一直保持着持续稳定的增长势头,成为行业的翘楚。1993年3月8日面市以来,太太口服液已连续畅销近十年,静心口服液上市三年来,销售也一直保持快速的增长态势,在2001年度销售更是势头迅猛,年销售额达21,656.62万元;同时,在OTC药品方面,太太药业陆续推出了意可贴、正源丹、汉林清脂等一系列产品,市场反应都极为积极,2000年推出的意可贴,更是用小药做出了大市场,赢得了非常理想的市场份额和患者口碑。2001年6月8日,深圳太太药业股份有限公司在上海证交所挂牌上市,并一举融资17亿,2002年4月3日太太药业股份有限公司发布公告,拟变更募集资金用途,用于收购健康药业“中国”有限公司100%股权及购买鹰牌商标物注册商标所有权。此次受让健康药业股权及鹰牌商标款共计折台人民币14,151万元。这是太太药业上市面上后首次的收购行动,也是资本在太太药业身上的首次说话。太太,已经变得越来越强大,用太太药业董事长朱保国的话说:低于10亿美元,别想买太太药业。那么,太太是如何取得今天的成就的呢?     

被覆自体微粒皮的辐照氟银猪皮移植治疗深度烧伤15例报告

OBJECTIVE: To study the feasibility of using irradiated porcine skin impregnated with fluorine and silver covered by autogenous skin granule graft in the treatment of severe burn injury. METHODS: Autogenous split-thick skin grafts were cut into small pieces (<1 mm3), which were transferred onto the sheet of porcine skin mounted with a layer of Xinnaxing ointment (2 mm in thickness). After eschar removal, the burn wound was covered with the prepared porcine skin, sutured and fixed with small holes at the lower site for drainage. The growth of autogenous granule skin was then observed and the criteria for therapeutic effect evaluation drafted. RESULTS: The layer of Xinnaxing ointment on the the porcine skin improved the adhesion of the autogenous small skin grafts, therefore full use could be made of the donor skin source. In the 15 patients receiving this treatment, the graft-covered area was (12.3+/-3.5) % that of the wound, with the donor-recipient area ratio of 1: (11.0+/-2.7) and subsequent healing time of 27.5+/-5.5 d. Primary healing was achieved in 9 cases, and secondary healing in 6, demonstrating similar clinical effect to that of allo-skin grafting. CONCLUSION: The method is easy and economic, which saves autogenous skin source and produces satisfactory clinical effect.

Promoting effect of the Chinese medicinal herb, wikstroemia chamaedaphne and tung oil extracts on carcinoma of the uterine cervix induced by HSV-2 or methylcholanthrene (MCA) in mice

The promoting effect of the Chinese medicinal herb, Wikstroemia chamaedaphne and Tung oil extracts (WC and HHPA) on carcinoma of uterine cervix induced by HSV-2 or MCA in mice was studied. The results showed that WC and HHPA extracts were not carcinogenic themselves. After carcinogen HSV-2 and MCA treatment, WC and HHPA were added separately. The inducing rates by HSV-2 increased from 7.4% to 21.1% and 26.3%, those by MCA increased from 56.5% to 82.8% and 84.4%. There was a significant difference between the combined groups and groups with HSV-2 or MCA only. The experimental results suggest that these two kinds of extracts play a promoting effect on carcinogenesis. The relation between the carcinogenesis of uterine cervix or nasopharynx and WC or HHPA extracts is discussed.     

JX-1对雄性小鼠生殖细胞致突变作用的研究

本文采用小鼠精子试验和小鼠睾丸DNA合成抑制试验,检测了JX-1对雄性生殖细胞的致突变作用。实验结果表明JX-1对小鼠精子总数、精子活动率及精子畸形率均无统计学意义的增加,与小鼠睾丸DNA合成抑制试验阴性反应一致。作者认为JX-1对雄性生殖细胞为一种非诱变剂。
