Objective To explore the strategies of prevention and treatment of MRSA infection in ICU patients. Methods The clinical data of 6 patients with MRSA infection occurring at the same time in ICU were reviewed retrospectively. Results Vancomycin was given in 4 cases, 250mg twice daily, and teicoplanin was given in one case, 400mg once daily. MRSA cultures were negative in 5 cases after antibiotic treatment. Conclusions MRSA infection occurs frequently in ICU patients, and it spreads readily. Antibiotic treatment, isolation and bacteriological monitoring are very important measures for control of MRSA infection in ICU patients. [HS(1*2/3]

Objective In the present study we examined the roles of three proinflammatory cytokines, i.e. tumor necrosis factor-?(TNF-?), interleukin 1?(IL-1?), and IL-8 in the early phase of APTE, and analyze the impact of these cytokines on the systemic circulation. Methods APTE was induced in 7 anesthetized dogs by injecting the thrombus of own blood into the right jugular vein. Seven animals receiving only warm sterile saline served as controls. Arterial serum samples were collected regularly (0h, 0.5h, 1h, 2h, 4h, 6h) and cytokine levels could be measured by radio-immunity assay. Results Introduction of clots into the pulmonary circulation caused significant increase in the mean pulmonary arterial pressure(from 99.1?5.7 to 66.8?15.3mmHg, P

Objective On the basis of the Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ), to establish and appraise a new prognostic evaluation system for elder patients with respiratory failure undergoing mechanical ventilation in order to predict hospital mortality in the respiratory intensive care unit. Methods Two hundred and thirty-eight senile patients with respiratory failure having had mechanical ventilation during their hospitalization were retrospectively analyzed. Patients were randomly divided into 2 groups: model group (n=138) and validation group (n=100). Data of model group were analyzed by monofactorial and multifactorial regression analysis to screen the risk factors. Risk factors were given numerical values according to different grades, and complementary scoring system was then established. APACHE Ⅱ system was combined with complementary scoring system with Logistic multiple regression to form SRFMV system, a special evaluation system for the senile patients with respiratory failure undergoing mechanical ventilation. One hundred patients from validation group were evaluated by both SRFMV system and APACHE Ⅱ system, and the results were then compared to assess the validity and reliability of SRFMV system. Oxygenation index, positive end expiratory pressure (PEEP), tidal volume, phlegm quantity and character, and pulmonary auscultation were selected to serve as standard for complementary scoring system. Mortality equation was set up with logistic multiple regression analysis. Results The predication sensitivity and specificity evaluated by SRFMV system in validation group (0.878 and 0.821, respectively) outstripped that evaluated by APACHE Ⅱsystem (0.818 and 0.771, respectively); the area under ROC curve in SRFMV system and the X2 value in Lemesshow-Hosmer statistic (0.911 and 13.77, respectively) also outstripped that in APACHE Ⅱsystem (0.860 and 11.808, respectively). Conclusions SRFMV system is of better sensitivity and specificity, in which the prediction of mortality is closely consistent with the reality. SRFMV system can be applied to obtain valid predictions of relevant outcomes in senile patients with respiratory failure underwent mechanical ventilation.

Objective To evaluate systematically the clinical efficacy of surgery combined with anti-TNFalpha in treatment of Crohn's disease (CD) with perianal fistula.Method Database including China Biology Medicine disc,Wan Fang Database,PubMed,Cochrane Library and EMBASE were searched withCrohn's disease,anal fistula,fistula,perianal fistula,surgical procedure,surgery,surgical,anti-tumor necrosis factoralpha,anti-TNF-alpha,TNF-alpha,克罗恩病,Crohn's病,肛瘘,手术治疗,外科手术,抗肿瘤坏死因子α制剂,肿瘤坏死因子,肿瘤坏死因子配体超家族员2”between the database establishment and June 2016.Literatures of retrospective case-control studies about surgery combined with anti-TNF-alpha therapy and single surgery in treatment of CD with perianal fistula were retrieved.Data were extracted and evaluated by 2 independent researchers.Patients who underwent surgery combined with anti-TNF-alpha therapy were allocated into the combined therapy group and patients who underwent single surgical treatment were allocated into the surgery group.The complete healing rate,partial healing rate and recurrence rate after therapy were compared between the 2 groups.Count data were represented as the odds ratio (OR) and 95% confidence interval (CI).The heterogeneity was analyzed by theI2 test.Result Six retrospective case-control studies were retrieved and total sample size was 598 patients,including 256 in the combined therapy group and 342 in the surgery group.The result of Meta analysis showed that there was no significant difference in postoperative complete healing rate and partial healing rate between the 2 groups (OR =1.36,1.47,95 % CI:0.94-1.97,0.56-3.88,P > 0.05),and recurrence rate after therapy in the combined therapy group was significantly lower than that in the surgery group (OR =0.26,95% CI:0.16-0.44,P < 0.05).Conclusion The complete healing rate and partial healing rate of patients with CD with perianal fistula undergoing surgery combined with anti-TNF-alpha therapy are not superior to that undergoing single surgical treatment,however,recurrence rate after therapy is lower for patients undergoing surgery combined with anti-TNF-alpha therapy.

This paper demonstrates the successful application of a novel approach to the computer aided design (CAD) of removable partial denture (RPD) framework. Firstly, we get the data of the partially edentulous cast, a mandibular Kennedy Class II, through a 3D-optical grating measuring system after corresponding pretreatment. Then, the reverse engineering software and 3D CAD software was used to design basis, big conjunction, clasp, small conjunction of the RPD framework. Finally 3D surface model of the RPD framework was created in preparation for direct manufacture using rapid prototyping (RP) methods and foundry. The result indicated that the RPD framework was fabricated successfully and the resulting frameworks provided a satisfactory fit.
