内源性感染

目的用分子流行病学方法研究呼吸机相关肺炎（VAP）内源性感染途径在VAP发病机制中的作用，为探索和发展全新的VAP预防措施提供理论依据。

OBJECTIVE To evaluate the role of endogenous infection route in the pathogenesis of ventilator-associated pneumonia ( VAP ) by molecular epidemiological methods , in order to explore and develop new prophylactic procedures of VAP .

大多数VVC患者为内源性感染（致病菌起源于阴道内或肛周），少数为外源性（性传播）感染。

Most of VVC patients were endogenous infection ( pathogenic origin from the vagina or anus ), a small number of them were exogenous ( sexually transmitted ) infection . Conclusions : 1 .

方法用背部烫伤法和盲肠结扎穿刺法（CLP）建立大鼠烧伤模型和内源性感染模型，用试剂盒测定血浆TNFα和MDA水平。

Methods The rat models for sepsis and burn were established and ELISA was used to determine the levels of TNF - α and MDA .

结论病原菌的PFGE同源性分析表明ICU中VAP患者存在胃腔→下呼吸道逆向内源性感染途径。

CONCLUSIONS The PFGE homologous analysis of pathogen might show that the reverse stomach-lower respiratory tract infection route could exist in VAP patients in ICU .

病原菌的PFGE同源性分析表明ICU中52例VAP患者有15例（其中14例为晚发性VAP）存在胃腔→下呼吸道逆向内源性感染途径，占VAP发病总数的288%；

The reverse endogenous stomach-lower respiratory tract infection route was verified in 15 cases ( among them 14 cases were late-onset VAP ) of the total 52 VAP patients by PFGE analysis , with the incidence of 28.8 % .

结论：①内源性感染和混合感染仍是急腹症外科感染性疾病的主要特征。

Conclusion : ① Acute abdomen surgical infections were characterized by opportunistic and endogenous existed pathogens .

结果内源性感染是机体在促使细菌易位的临床因素影响下，正常微生物群定位转移的结果。

RESULTS Endogenic infection was a result of translocation of normal microbiota in the body under the influence of clinical factors .

结论提高机体免疫力、控制内源性感染，是预防肿瘤感染的主要措施。

CONCLUSIONS The main prevention and control means of hospital infection among tumor patients are to improve the human immunity and control endogenous infections .

结论内源性感染是我院医院感染的主要部分：基础病严重、侵袭性操作、激素应用及不合理使用抗菌药物等是造成医院感染的主要危险因素；

CONCLUSIONS Endogenous infection is the main reason of hospital infection ; heavy primary disease , invasive examination , hormone application and irrational use of antibiotics are the main risk factors of hospital infection .

结果感染以中晚期患者为多，占83.6%，内源性感染为43.8%；感染部位以呼吸道为主，占59%；

Results The infection occurred more often in patients in mid-late stage ( 83.6 % ), with endogenous infection being 43.8 % and the infected regions were chiefly in the respiratory tract ( 59 % ) .

大多数妇女个人生活卫生习惯和性卫生行为良好，清洗外阴和洗澡频度不同的妇女内源性感染率差异具有统计学意义；

Personal hygiene practices and sexual behaviors among married women in the study were good in general . In terms of the prevalence of endogenous infection , there were statistical differences between women who had different frequencies of rinsing their vulvae and taking bath ;

Prevention of Endogenic Hospital Infection with Microecology Methods

目的论证用微生态学方法预防内源性医院感染发生的正确性和实用性。

OBJECTIVE To explore the correctness and practicability of microecology methods to prevent endogenic hospital infection .

目的由血红素氧合酶（HO）催化血红素分解代谢而形成的一氧化碳（CO）可能作为一种新的内源性介质参与感染性休克一系列病理生理过程。

Objective Endogenous carbon monoxide ( CO ), which was mainly produced through the metabolism of heme catalysed by hemeoxygenase ( HO ), was suggested to play a role in the pathophysiology of septic shock .
