重组人酸性成纤维细胞生长因子促进创伤愈合的研究

目的：研究重组人酸性成纤维细胞生长因子（rh-aFGF)对兔创伤的促愈合作用。方法：采用兔背部刀割伤模型，将rh-aFGF溶液隔日一次滴注于创面，用创面照像、透明膜描记称量法记录伤后第4、8、12、16天创面面积，用注水法测量伤腔容积，伤后第8、16天取创面组织，观察创面的病理学变化，包括肉芽组织生长与再上皮化情况。结果：rh-aFGF可明显加速兔皮肤创伤的愈合，使创面面积明显缩小（P＜0．05），使伤腔容积明显减少（P＜0．05）。组织学检查：rh-aFGF组创面伤后8天成纤维细胞生长活跃、数量多，其毛细血管胚芽与成纤维细胞数量显著多于对照组；伤后16天，创面收缩与再上皮化明显，新生上皮向创面中心爬行较快。结论：rh-aFGF对兔背部刀伤创面有明显的促修复作用。

准分子激光角膜屈光术后感染性角膜炎

准分子激光角膜屈光术后感染性角膜炎是准分子激光角膜屈光术后少见而严重的并发症，一旦发生，可对视力造成严重损害。完善的术前筛查及准备工作、术中严格的无菌操作、术后合理用药及定期随访、一旦感染发生能及时正确地处理可有效预防或控制感染，最大限度地减轻并发症对视力的损害。     

Biological characteristics of newly diagnosed poor prognosis acute myelogenous leukemia

A pilot study was conducted of the biological characteristics of the leukemia cells of newly diagnosed patients with poor prognosis acute myelogenous leukemia (AML). This study included measurements of the pretherapy proliferative rate of the leukemia cells in vivo, assessment of differentiation in vivo during remission induction therapy, and the level of expression of the fms, myc, and IL1β genes in pretherapy leukemia cells. Short cell cycle times were characteristic of the best prognostic category and were associated with a rapid reduction in marrow leukemia cells in cytosine arabinoside (araC)-sensitive patients. Expression of c-fms was associated with rapid reduction in marrow leukemia cells during araC therapy and with a successful treatment outcome. Expression of the IL1β gene was associated with short remissions. These studies suggest that when compared to newly diagnosed standard prognosis AML, the leukemia of poor prognosis patients is more likely to exhibit long cell cycle times, low levels of fms expression, and is less likely to be associated with myeloid differentiation during remission induction therapy. © 1993 Wiley-Liss, Inc.     

营养不良老年人非药物干预临床实践指南

老年人是营养不良的高发人群,营养不良与众多不良临床结局密切相关,严重影响老年人的身体健康和生活质量,给家庭和社会造成沉重负担。因此,采取有效措施改善老年人的营养不良至关重要,非药物干预是改善营养状况的重要措施。然而,国内尚无专门针对营养不良老年人的非药物干预临床实践指南,因此,中国老年护理联盟、国家老年医学中心和国家老年疾病临床医学研究中心的营养专家,通过对老年人营养不良最新的国内外文献的全面检索与分析,采用推荐意见评估、制订及评价(GRADE)分级体系制订了本指南,针对营养不良老年人非药物干预提出9条推荐意见,以期能够改善老年人营养不良状况,提高生活质量。本指南侧重于可经口进食的营养不良老年人,聚焦于肠内营养,肠外营养不在本指南讨论范围内。     

Use of an autovenous transplant, polytetrafluoroethylene prosthesis and human umbilical vein bioprosthesis for creating an arteriovenous fistula for programmed hemodialysis

The work presents an experience with 84 operations of making nonstandard arteriovenous fistulas in 75 patients using autovenous transplants, polytetrafluorethylene prosthesis and home bioprostheses from human umbilical veins made at plant "Sever". Results of the operations were followed-up during 3 years. It was shown that arteriovenous fistulas made of plastic materials generally have a higher level of complications and shorter terms of functioning as compared with ordinary fistulas. Nevertheless, using nonstandard fistulas is justified in a certain category of patients.
