OBJECTIVE To analyze the nosocomial infection cases,which were failed to be reported,and to grope for countermeasure to lessen the rate of nosocomial infection cases in disguise.METHODS The clinical data of the inpatients who were getting treatments in Oct 2004 and in Oct 2005 in the hospital were reviewed and analyzed.RESULTS The understanding and the recognition of nosocomial infection,the standards for judgement,the quatification of the medical workers,the medical cost and economic benefit ratio were all the causes that prevented nosocomial infection cases from being reported.CONCLUSIONS Propagandize the nosocomial infection management to make our medical workers attach importance to it,implement an objective obligation,constitute a hortative system,to exert the director's function and the workers′ enthusiasm,and choose high qualified workers to take charge in the nosocomial infection management,thus can prevent nosocomial cases from being reported.

Thermotherapy is one of the combined therapies of malignant tumor. It can enhance the sen-sitivity to radiotherapy by inhibiting cell DNA repair,changing cell signaling, modulating cell cycle checkpoint and inhibiting tumor cell metastasis. Many clinical trials have also confirmed that the combination of thermother-apy and radiotherapy can enhance the curative effect of head and neck,ventrum and pelvic malignant tumor. In this article,the synergistic effects and mechanism of tumor thermoradiotherapy are reviewed.

Objective To contrast and observe the bone marrow stem mobilization induced by Yiqi Wenyang Huoxuefang and G-CSF,and the influence to left ventricle reconstruction. Methods Model rat was made by ligate LAD,quantity of circulation stem cells(CSC) at the first,fifth and tenth day was detected. After be treated 8 weeks,the heart index,the expansion index and the thinning ratio were calculated. Results The quantity of CSC of Chinese herbs group increased at the fifth day(P

Fifty percent TBSA third degree burns was inflicted to 24 dogs and they were treated with immediate fluid infusion (8 dogs),delayed conventional infusion (n=8),and delayed fast infusion (n=8),It was found that in the immediate and delayed fast infusiong groups,strike volume,strike index, left ventricular strike work index,right ventricular strike index and femoral arterial pressure were maintained at a level more than 50% of the normal and were gradually restored.Their pulmonary artery wedge pressure was larger than 1.3 kPa.ALT and LDH were increased but never exceeded the preburn level.DB,TB,UN,Cr,PaO2,P(A-a)O2 were maintained in the normal range.MDA RCR,ADP/O,ATP,positive blood culture rate,mortality rate and morbility of multiple organ failure were all lower than those of the delayed conventional infusion group.It is believed that in the early stage of burn injury,the development of multiple organ failure can prevented effectively with immediate infusion and partially with delayed fast infusion while delayed conventional infusion exerts no protection at all.

Objective To analyze clinical distribution and drug resistance of extended-spectrum β-lactamase(ESBLs)-producing and non ESBLs-producing Escherichia coli(E.coli) isolated from 2014 to 2015.Methods Collected 4 721 clinical specimens from January 2014 to December 2015,separated and identified by using VITEK 2-Compact automatic microorganism identification and sensitivity analysis system of Biomerieux,France.Results A total of 1 181 E.coli were isolated from 4 721 clinical specimens,the isolation rate was 25.02%,and the isolation rates of 2014 and 2015 were 17.38% and 19.24% respectively.Meanwhile,the isolation rates of ESBLs-producing E.coli from 2014 and 2015 were 44.46% and 51.71%,increased 7.25%.For the ESBLs-producing E.coli,the main specimens from urine,sputum,blood,appendix content,pus and secreta,and general surgery department,pneumology department,urology,Neurosurgery departments were the main infection departments.For the non ESBLs-producing E.coli,the main specimens from urine,blood,sputum,appendix content,pus and secreta.The drug resistance of E.coli to antibiotics showed increasingly upward trend from 2014 to 2015.However,it showed high sensitive to amikacin,imipenem and meropenem.Conclusion As the isolation rate of E.coli increased in 2015,so does the drug resistance,and it is need combine with the actual situation of medication to regulate the usage of antibiotics.

OBJECTIVE:To understand the prophylactic antibiotics use in general surgeries performed in the hospital where the authors work.METHODS:500copies of discharge record of common surgical cases written between Jul.2005and Feb.2006were checked randomly,and the questionnaires about the general data and medication of the patients were filled out.Then the collected data were analyzed statistically.RESULTS:The prophylactic drug use rate in TypeⅠincision operations reached up to98.8%,of which58.5%cases lacked clear indications of medication.The high rate of prophylactic drug use,improper time of drug use,and the prolonged continuous drug use were among the problems that existed in TypeⅠand TypeⅡincision operation.CONCLUSION:There remain many problems in the use of prophylactic antibiotics in the general surgeries performed in our hospital,which requires the strengthening of standardized administration of prophylactic antibiotic use.

Objective To study the clinical diagnosis value and CT features of gastric fundus and cardiac part lesions.Methods The CT findings and examining method of gastric fundus and cardiac part lesions were analyzed and summarized in 64 cases.Results (1)Use water as oral contrast can show the gastric mucosa clearly,it was a simple,effective way.(2)CT had important significance for stages and infiltration of cardiac cancer.(3)Varix of gastric fundus had three types:pseudotumor,tuber and thinking-wall.(4)The CT characteristic features of leiomyoma were the continuous linear enhancement in mucosa.Conclusion CT is method for gastrointestinal examining,it has special value to the gastric fundus and cardiac part lesions.

Patients' safety is a hot topic of hospital management all over the word. Strengthening the patients' safety education for medical students and nursing students is an effective measure to protect patients' safety. In nursing school of Chongqing Medical University,patients' safety education was con-ducted through the course of undergraduate education. Contents of patients' safety education were com-bined with the professional courses,which are taught step by step in the professional course learning phase for different grades. Patients' safety education took a lot of teaching forms to cultivate the students' patient safety consciousness and preliminary results were achieved.

Objective To study the relationships of alcohol consumption to the prevalence of metabolic syndrome and its re‐lated components in Yichang professional population and provide decision making basis for lifestyle intervention to MS crowd in the city .Methods We examined baseline data from 3 640 participants (2 285 men and 1 355 women) aged 20 to 70 years who under‐went a careful drinking habits survey ,then physical examination and blood chemical examination .They were divided into three groups by average ethanol intake [non ,occasional (<10 g/day) ,moderate (≥10 and <30 g/day) ,and heavy (≥30 g/day) drink‐ers] .Results Compared with no drinking and occasional drinking group ,the prevalence of MS and abnormal rate of BMI ,DBP ,TG , UA increased significantly (P< 0 .05) while SBP decreased significantly in moderate drinking group;compared with moderate drinking group ,the prevalence of MS and abnormal rate of BMI ,DBP and SBP ,GLU ,TCH ,TG ,LDL C ,UA increased significantly (P<0 .05) in heavy alcohol consumption group;whether moderate or heavy drinking ,abnormal rate of CRP and HDL C did not change significantly(P>0 .05) .Conclusion Even moderate drinking has a significant effect to BMI ,DBP ,TG ,LDL C ,UA ,but not obvious to CRP ,GLU ,TCH ,HDL C .Excessive alcohol consumption has a very bad effect on BMI ,DBP ,SBP ,GLU ,TCH ,TG , HDL C ,LDL C ,UA .Both the prevalence of MS and the abnormal rate of its related components are proportional to the alcohol in‐take .Although moderate drinking could lower SBP and GLU ,but can not reduce the incidence of MS .
