[Objective] To investigate the result from continuous quality improvement of care management in the prevention of ventilator-associated pneu-monia(VAP).[Method] The ICU patients from June to December 2010 were selected in a control group before the continuous quality improvement ,and the ICU patients from January to June 2011 were selected in the observation group after the continuous quality improvement. Before and after the contin-uous quality improvement,to investigate and analyze their knowledge on VAP and their adherence of continuing implementation about the VAP bundle nursing strategy in 26 medical staff.[Results] After the continuous quality improvement ,there was more significantly difference in their knowledge on VAP and their adherence of continuing implementation about the VAP bundle nursing strategy than before. By the continuous quality improvement, the VAP infection rate decreased from 41.2%to 23.7%,and the difference was statistical y significant. [Conclusion] In the care management for preventing VAP ,the application of continuous quality improvement management can increase the awareness of VAP ,improve the implementation of VAP prevention and con-trol measures,and reduce the incidence of VAP.

A melanoma is a highly malignant tumor that originates from melanocytes in the skin, mucosa, or tunica pigmentosa. The incidence and mortality rate of cutaneous melanoma are increasing annually. However, the efficacy of traditional therapy is extremely limited because of its low sensitivity and high toxicity. The application of the anti-CTLA-4 antibody and the BRAF inhibitor dramatically improves the overall survival of patients with advanced melanoma. However, their limited benefit ratio and high drug resistance curtail the use of anti-CTLA-4. Since the US Food and Drug Administration approved the use of the anti-PD-1 and anti-PD-L1 antibodies for ad-vanced melanoma in 2014, a significant survival benefit has been observed in patients with advanced melanoma. This review aims to highlight the applications of the anti-PD-1 antibody (pembrolizumab, nivolumab, and pidilizumab) and the anti-PD-L1 antibody (MP-DL3280A, BMS-936559, and MEDI4736) in the clinical treatment of melanoma by succinctly summarizing the results of recent reports.

Objective To investigate the dynamic expression of SOCS-3, TNF-α in live and spleen of mice induced by AOPP, and to discuss the mechanism of MODS induced by AOPP, so that to give some intervention method over MODS in the future. Method Thirty-six adult BALB/c mice were divided into 3 groups randomly: AOPP group (n=12). Water normal group (n=12) and normal group (n=12). After post poison 2 hours, 6 hours, 12 hours and 24 hours,the fiver and the spleen tissue were taken out. The expression of SOCS-3 and TNF-α were detected by RT-PCR. And data were analyzed with ANOVA. Results After AOPP of 2,6,12,24 hours, the mRNA expression of SOCS-3 increased obviously in the liver and spleen compared with the normal group (P<0.05), it reached peak at the 24th hour in liver,and reached peak at the 12th hour in spleen, then descended at 24th hour (P<0.05). The mRNA expression of TNF-α increased obviously in the liver and spleen than normal group (P<0.05), and reached peak at the 12th hour,then descended at 24th hour (P<0.05), the electro-phoresis image of RNA was 5 s 15 s and 30 s,RT-PCR amplification of β-actin showed,the expression of SOCS-3, reached peak at the 24th hour in liver and it reached peak at the 12th hour in spleen, then descended at 24th hour (P<0.05), TNF-α reached peak at 12th hour in the liver and spleen, then descended at 24th hour. By statistic analysis, positive correlation was indicated among SOCS-3 and TNF-α mRNA expression in liver (y=0.089+0.758x, r=0.939, F=252. 168, P<0.01) positive correlation was indicated among socs-3 and TNF-α mRNA expression in spleen (y=0.057+0.361x,r=0.953,F=336.122, P<0.01). Conclusions At different point of time after Aopp,the mRNA expression of socs-3 and TNF-α showe the same trend in liver and spleen,the levels of SOCS-3, TNF-α all increase significenfly.

Objective The coronary slow flow phenomenon (CSFP) is a coronary artery disease with a benign course,but its pathological mechanisms are not yet fully understood.The purpose of this controlled study was to investigate the cellular content of blood in patients diagnosed with CSFP and the relationship of this with coronary flow rates.Methods Coronary angiographies of 3368 patients were selected to assess thrombolysis in myocardial infarction (TIMI) frame count (TFC) values.Seventy eight of them had CSFP,and their demographic and laboratory findings were compared with 61 patients with normal coronary flow.Results Patients'demographic characteristics were similar in both two groups.Mean corrected TFC (cTFC) values were significantly elevated in CSFP patients (P ＜ 0.001).Furthermore,hematocrit and hemoglobin values,and eosinophil and basophil counts of the CSFP patients were significantly elevated compared with the values obtained in the control group (P =0.005,P =0.047,P =0.001 and P =0.002).The increase observed in hematocrit and eosinophil levels showed significant correlations with increased TFC values (r =0.288 and r =0.217).Conclusion Significant changes have been observed in the cellular composition of blood in patients diagnosed with CSFP as compared to the patients with normal coronary blood flow.The increases inhematocrit levels and in the eosinophil and basophil counts may have direct or indirect effects on the rate of coronary blood flow.

Objective_ To investigate the effect of resting heart rate on the progression to diabetes in impaired glucose regulation patients. Methods A total of 638 patients with impaired glucose regulation, from January 2011 to December 2012 in our endocrinology clinic, were selected for the study. According to the resting heart rate, patients were divided into four groups:<66 beat/min group, 66 to 69 beat/min group, 70 to 75 beat/min group, and>75 beat/min groups. All patients'baseline data were collected. The incidences of diabetes in different resting heart rate groups were compared, and the relationship between resting heart rate and the progression to diabetes was estimated using multiple regression analysis. Results In 704 patients with impaired glucose regulation, 636 patients have been completed 2 years follow-up, or reached the end of follow-up ( diagnosed as diabetes ) , the follow-up rate was 90. 34%. During two years follow-up, the incidence of diabetes of<66 beat/min group, 66 to 69 beat/min group, 70 to 75 beat/min group, and>75 beat/min group were 16. 2%, 19. 4%, 25. 0%, and 33. 0%, respectivlely. And the Cochran Armitage trend test showed that χ2 =11. 109, P=0. 001, the difference was statistically significant ( P<0. 05). According to blood glucose monitoring, the 636 patients with impaired glucose regulation were divided into impaired fasting glucose group, impaired glucose tolerance group and impaired fasting glucose combined with impaired glucose tolerance group:the Cochran Armitage trend test showed that, with the resting heart rate accelerating, the incidence of diabetes increased. The incidence of diabetes in impaired fasting glucose combined with impaired glucose tolerance group was higher than that of impaired fasting glucose group and impaired glucose tolerance group ( P=0. 062, 0. 113). The average resting heart rate in 68 impaired glucose regulation patients progressed to diabetes was (79.8±8.3)beat/min,andin568non-diabetescases,itwas(74.5±7.2)beat/min(t=-5.043,P<0.01). With the use of patients progressing to diabetes as the dependent variable, different resting heart rate group as independent variables, and resting heart rate<66 beat/min group as a reference, the logistic regression analysis showed that the risk of the progression to diabetes increased with the resting heart rate levels. Conclusion Higher resting heart rate is linked to higher risk of diabetes in patients with impaired glucose regulation.

Objective To examine the usefulness of shock index (Sl) and adjusted shock index (corrected to temperature) (ASI) in predicting prognosis of patients with return of spontaneous circulation after cardiac arrest.Methods A prospective study,which data such as vital signs of the cases were collected by the Utstein template,was conducted in 111 of cases with return of spontaneous circulation after cardiac arrest to assess the value of SI and ASI for predicting their prognoses.Results There was no evidence to show difference between the cases with survival to hospital discharge and the ones who died about systolic blood pressure and heart rate (P ＞0.05).SI and ASI [(1.109 ±0.428) and (1.082 ±0.410)] of the group of death were higher significantly than the ones [(0.899 ± 0.303) and (0.844 ± 0.265)] of the group with survival to hospital discharge,P ＜ 0.05.The risk of death was elevated in the group with ASI ＞ 1.1,which odds ratio (5.4) higher than the ones of systolic blood prcssure ＜90 mm Hg (1.6)and ventricular rat ＞ 100 beat/min (3.1) significantly.The odds ratio of death with AS ＞ 1 was 2.8.Conclusions Shock index and adjusted shock index are easy to derive and conducive to predict effectively diseases prognosis such as survival to hospital discharge or death of patients with ROSC.

Objective: To investigate the characteristics of etiology and drug resistance of nosocomial infection in the neurosurgery intensive care unit(NICU),and provide useful information for clinical practice.Methods: We analyzed the clinical data of 179 cases of nosocomial infection among 1 163 patients admitted in the NICU from June 2005 to March 2007.Results: From the 179 patients,346 strains of bacteria were obtained,of which Gram's negative bacili accounted for 52.89%,Gram's positive cocci 38.15% and fungi 8.96%.Of the diagnosed nosocomial infections,83.80% involved the lower respiratory tract,10.61% the urinary tract,2.79% the blood vessels,1.68% the central nervous system and 1.12% the hematological system.Conclusion: To reduce nosocomial infections in the NICU,emphasis should be placed on the control of lower respiratory tract infection as well as on the prevention and treatment of Gram's positive coccus infection in the acute stage and Gram's negative bacillus infection in the later stage.Intensified prevention measures based on the standard ones could help to get the drug-resistant strains under control.
