Laparoscopic subtotal gastric resection for chronic gastric ulcers.

OBJECTIVES: We analyzed our experience with the laparoscopic approach for treating benign gastric lesions. METHODS: Between June 1998 and June 2002, we performed 18 gastric resections with the laparoscopic approach for 7 pyloric stenoses, 8 recurrent duodenal ulcers, and 3 chronic gastric ulcers. RESULTS: In our series, we performed Billroth II laparoscopic distal gastrectomy with no morbidity and mortality. CONCLUSIONS: Billroth II laparoscopic distal gastrectomy is safe in cases of benign gastric or duodenal lesions.     

采血者针刺伤的调查及危险因素分析

针刺伤在采血工作中经常发生，其危害大，后果严重，一般情况下还没有引起人们足够的重视。我国是肝炎的高流行区，近年来艾滋病在我国的发病率呈倍增的趋势。血液污染的针刺伤是导致血站采血人员发生血源性传染病最主要的职业因素。作者从实际工作出发，收集相关资料，系统的阐述了针刺伤的发生因素及预防措施等，并结合相关理论提出了一系列的措施和建议。     

Differential diagnosis of leg ulcers

In Germany about 0.7 % of the adult population have a chronic leg ulcer. Although chronic venous insufficiency accounts for at least 80 % of all chronic leg ulcers, knowledge of the relevant differential diagnostic considerations is of crucial importance, in particular for patients who are refractory to therapy. In addition to vascular disease, other causes include neuropathic, metabolic, hematologic and exogenous factors as well as neoplasias, infections, drugs, genetic defects and some primary skin disorders. For the long‐term successful treatment of patients with chronic leg ulcers, it is necessary to identify all relevant factors, in order to enable a pathogenesis‐oriented, interdisciplinary therapeutic approach.     

甘草酸及肾十方治疗慢性马兜铃酸肾病26例疗效观察

目的观察甘草酸及复方中药肾十方对慢性马兜铃酸肾病的疗效。方法26例符合慢性马兜铃酸肾病的患者，给予甘草酸二铵150mg加中药复方汤剂肾十方治疗3个疗程。观察治疗前后尿素氮（BUN）、血肌酐（SCr）、尿酶及24h尿蛋白排泄量，血红蛋白、红细胞压积。结果治疗后患者临床症状有显著改善，总有效率80.76％；BUN、SCr、尿N-乙酰葡萄胺酶（NAG）、β2-微球蛋白（β2-MG）均显著下降（P〈0．05），血红蛋白、红细胞压积较治疗前升高（P〈0．05）。结论甘草酸及复方中药肾十方对慢性马兜铃酸肾病有确切的疗效。     

延边地区农村朝、汉族肥胖与慢性病危险因素关系分析

目的：分析延边农村地区朝、汉族肥胖与慢性病危险因素关系。方法：随机抽取延边地区农村50～60岁朝、汉族常驻人群447名，采用面对面询问法进行问卷调查，观察不同民族体质指数（BMI）、腰围（WC）水平与慢性病危险因素-血清总胆固醇（TC）、高密度脂蛋白胆固醇（HDI—C）、甘油三醋（TG）、收缩压（SBP）、舒张压（DBP）及血糖（FBG）的关系。结果：不同民族居民WC、SBP、DBP、FBG及HDL—C分布特征存在差异。不同民族BMI、WC与慢性病危险因素的相关性存在差异。结论：制定延边地区慢性病防治策略和措施时应考虑民族与肥胖种类的因素。     

Basic fibroblast growth factor and epidermal growth factor reverse impaired ulcer healing of the rabbit oral mucosa

BACKGROUND: The therapies for refractory ulcers on the oral mucosa are symptomatic and very unsatisfactory. We hypothesized that application of growth factors might be able to achieve successful remission of the lesion. We evaluated the effects of systemic administration and topical application of epidermal growth factor (EGF) and basic fibroblast growth factor (bFGF) on impaired wound healing of ulcers in the rabbit gingiva. METHODS: Almost uniform round ulcers could be created on the gingiva of the rabbits by chemical injury with acetic acid. When the submandibular glands were removed or i.v. injection of cisplatin (CDDP) and peplomycin sulfate was performed before ulcer formation, healing of the ulcers took longer than in untreated rabbits. To ascertain whether or not human EGF and bFGF affect rabbit cells, we first examined the effects of EGF and bFGF on the proliferation of the cells derived from rabbit gingiva. We then applied EGF or bFGF in these impaired healing models. RESULTS: EGF and bFGF promoted proliferation of the fibroblasts, and EGF also promoted proliferation of the keratinocytes isolated from gingival tissue of rabbits in vitro. Systemic injections of EGF and bFGF in rabbits, which had their submandibular glands removed, and topical application of bFGF accelerated healing of ulcers created in rabbits injected with CDDP and peplomycin sulfate. The ability of bFGF to promote the healing of ulcers was much greater than that of EGF. CONCLUSION: Basic FGF may be effective for refractory oral mucosal lesions.     

慢性肾衰竭急性加重的临床特征及相关因素分析

目的：探讨慢性肾衰竭（CRF）急性加重因素及其治疗措施对预后的影响。方法：对2001年1月～2005年6月住院治疗的CRF急性加重患者42例，按其加重原因、基础疾病、治疗方式和疗效进行回顾性总结。结果：CRF急性加重因素依次为各种感染（45．2％）、原发病加重（19．0％）、高血压未控制（14．3％）、水电解质紊乱（11．9％）、肾毒性药物（11．9％）、心功能不全（9．5％）、尿路梗阻（4．8％）、血高粘滞状态（2．4%），7例同时存在≥2种上述病因（16．7％）。CRF急性加重原发病以慢性肾小球肾炎（52．4％）和糖尿病肾病（11．9％）为主。积极治疗后肾功能恢复达到或接近原来水平者40例，死亡2例，死亡2例的年龄均在60岁以上。结论：对于CRF肾功能急剧恶化的患者，应积极寻找其加重因素，并采取非透析和透析相结合治疗，改善肾功能，降低病死率，延长患者生命。
