低温等离子灭菌器是医院消毒供应中心一种较为常见的医疗设备,其工作原理主要是利用过氧化氢在极度真空的灭菌舱环境中汽化后均匀扩散到整个空间,再由高频电压产生高频电场使得过氧化氢气体形成等离子体体系,多个因子间共同起到杀菌的效果。灭菌处理的全部过程均是在干燥的低温情况下进行,所以基本不会对医疗器械产生破坏作用,且不会残留任何毒性,因此其在金属与非金属的灭菌处理中均可使用。本院使用山东新华PS-100低温等离子灭菌器,为医疗器械灭菌消毒工作提供了诸多便利,但使用期间曾出现真空期超时、提纯器温度太低、扩散期压力太低、线路等故障,现就其检修过程进行分析,以供参考。 相似文献

王檀教授认为,哮病具有迁延难治且反复发作的特点,在北方严寒之地其发病率更为突出.引起哮病发作的原因错综复杂,其病因无外乎外感及内因.提出"哮病主于火"及"五脏六腑皆令人哮"为哮病的病机关键.从脏腑相干理论出发提出哮病因火、热而哮,因痰而作.治疗时,当辨清五脏六腑的寒热虚实,调整脏腑功能,尤其脾胃的功能的健运.从火、热论治哮病,发则治其标,缓则治其本. 相似文献

Aerobic glycolysis plays a key role in cancer cell metabolism and contributes to tumorigenesis, including that of non-small cell lung cancer (NSCLC). Tanshinone IIA (Tan IIA), an active compound of Salvia miltiorrhiza, exhibits antitumor properties. Multiple mechanisms are involved in the antitumor action of Tan IIA in lung cancer, such as inhibiting cell growth, promoting cell apoptosis and influencing cellular metabolism. However, the effects of Tan IIA on NSCLC cells and its mechanisms of action remain unclear. The present study shows Tan IIA dose-dependently attenuated the growth of NSCLC cells and in vitro in a dose-dependent manner. Moreover, Tan IIA markedly decreased the ATP level, glucose uptake and lactate production in the NSCLC cells in vitro. Tan IIA also inhibited tumor growth in a xenograft model in vivo. Mechanically, Tan IIA treatment decreased sine oculis homeobox homolog 1 (SIX1) mRNA and protein levels, thus leading to the downregulation of pyruvate kinase isozyme M2, hexokinase 2 and lactate dehydrogenase A (LDHA) expression in A549 cells. SIX1 knockdown with small interfering-RNA inhibited glycolysis in NSCLC cells, suggesting that SIX1 plays a role in the antitumor effect of Tan IIA on NSCLC cells. More importantly, it was demonstrated that SIX1 expression was stimulated in patients with NSCLC and was positively correlated with the LDH serum level. Finally, SIX1 low expression levels predicted the poor prognosis of patients with NSCLC. In conclusion, the present study showed that Tan IIA functioned as an anti-glycolysis agent in NSCLC cells by downregulating SIX1 expression and inhibiting cell proliferation. 相似文献

PURPOSE: To examine the influence of tan preference and skin type on sun protection behaviors of Australian adolescents. METHODS: The Australian Secondary School Alcohol and Drug Questionnaires were conducted in 1993, 1996, 1999 and 2002 among randomly selected students aged 12--17. Schools were randomly selected from each education sector in each state. The self-administered questionnaire contained questions about tan preferences, skin type and usual SunSmart behavior (use of sunscreen, hats and covering clothing). RESULTS: The routine use of SunSmart behavior was low in all survey years. There was a significant decrease over time in the proportion of students who practiced SunSmart behavior, with prevalence rates lower in 2002 than in any other survey year (males: p<0.01 and females: p<0.01). As desire for a tan increased, routine practice of SunSmart behaviors decreased. Across the four survey periods, male (p<0.01) and female (p<0.01) students who preferred no tan were significantly more likely to practice SunSmart behavior than students who preferred any sort of tan. Across the four survey years, male (p<0.01) and female (p<0.01) students with skin that 'just burns' were most likely to routinely practice SunSmart behavior. CONCLUSIONS: Sun protection practices among adolescents have continued to decline significantly over time. Future educational programs require an innovative approach to modify adolescent behaviors in relation to sun exposure and sun protection. 相似文献

Background
Recurrent pyogenic cholangitis (RPC) is a known risk factor for intrahepatic cholangiocarcinoma (ICC), whether it represents a poor prognostic factor remains controversial. The aim of this study was to investigate the post-hepatectomy oncological outcomes of patients with ICC and coexisting RPC.Method
A retrospective analysis with propensity score matching (PSM) was performed for comparison between ICC patient with and without RPC.Results
There were 143 patients with ICC with a median follow-up of 21 months. RPC was diagnosed in 18% of patients. The time from RPC diagnosis to ICC diagnosis was 137(47–481) months. The 3-year disease-free (DFS) and overall survival for the whole population was 34% and 43% respectively. Preoperative child score, elevated carcinoembryonic antigen, presence of microvascular invasion, multiple tumours, presence of postoperative complications and RPC were independent factors for DFS and OS. After PSM, 60 ICC patients who did not have RPC were compared with 20 ICC patients with RPC. Patients with RPC had significantly worse median DFS (10 vs 23 months, P = 0.020) and OS (15 vs 45 months, P = 0.004) when compared to the patients without RPC.Conclusion
RPC represents a poor prognostic factor affecting outcomes after hepatectomy for patients with ICC. 相似文献50.
