Objective To investigate awareness about tuberculosis (TB) prevention and treatment and influence of professional training on TB detection among health-care workers (HCWs) in general hospitals.Methods In total,750 HCWs were trained for TB-related knowledge for eight class-hours in a two-day course in three general hospitals,and 20 HCWs from each of the three hospitals classified as grade 3A and grade 2A in urban Beijing and grade B at suburban Beijing,respectively,were interviewed with questionnaire designed to understand their awareness about TB prevention policy,epidemiology,diagnosis and treatment,and to evaluate effectiveness of the training,respectively.All the trainees responded before and after the training,with a hundred percent of response rate.TB diagnosis and reporting one year before training in the three hospitals were compared to those one year after it.Results Scores of knowledge about TB diagnosis and treatment averaged 64-80 for HCWs before training,with statistically significant difference among three hospital (F = 5.984,P ＜ 0.01).Scores increased after training,but without significant difference from those before it (P ＞ 0.05).Awareness of TB prevention policy,regulations and epidemiology was insufficient in most HCWs of those hospitals,with lowest and highest average scores of 38.3 and 71.7 before training,respectively,but scores increased significantly after training (P ＜ 0.01).Proportion of TB diagnosis with chest roentgenograph at grades 3A and 2A hospitals was significantly higher one month,three months and six months after training,as compared to that at suburban hospitals (P ＜0.01).There was significant decrease (P ＜ 0.01) in proportion of chest roentgenograph at respiratory departments in hospitals grade 3A and grade 2A after training.There was no significant difference in reporting of pulmonary TB and positive sputum smear (P ＞ 0.05) before and after training.Conclusions HCWs in general hospitals had experience and capacity in diagnosis and treatment of pulmonary TB,but their knowledge of TB prevention policy and epidemiology was insufficient.Their ability in finding and reporting TB can not been improved with short-term training.

OBJECTIVE To study the carbapenemase genotypes among Acinetobacter calcoaceticus isolates infected after liver transplantation. METHODS The 5.4 software was used to analyze the resistance of Acinetobacter species. Eight strains of imipenem-resistant A. calcoaceticus which were resistant to multiple drugs were collected. Analytical isoelectric focusing electrophoresis was used to measure the pI of the ?-lactamase. The homology of the isolates was determined by pulsed field gel electrophoresis(PFGE). blaTEM, blaSHV, blaIMP, blaVIM, blaOXA Genes for resistant isolates were amplified and sequenced. RESULTS Imipenem-resistant A. calcoaceticus infected after liver transplantation was resistant to multiple drugs. All of 8 strains were produced OXA-23 carbapenemases (pI of 6.7). The results of PFGE indicated there was a trend of resistant clone transmisstion in the transplantation ward. CONCLUSIONS There is a transmisstion of A. calcoaceticus producing OXA-23 carbapenemase in the transplantation ward of our hospital. It is important to monitor powerfully the bacterial resistance to control infection more effectively.

AIM:To investigate the effect of exogenous epidermal growth factor(EGF) on expression of EGFR and EGF mRNA of the injuried lung tissue of neonatal premature rats exposed to hyperoxia.METHODS:The neonatal Sprague-Dawley rats of 21-day gestational age model of hyperoxia induced lung injury were made by continually inhaling 95% oxygen.The model rats were divided into two groups randomly,the EGF trail group and the NS control group.The other rats were taken into the air control group.Each group was divided into three subsets:a(1-3 days),b(4-6 days) and c(1-6 days) according to different application times of EGF or NS.Rats in sub groups were executed and the lung tissues were removed at postnatal 3th,7th,14th day respectively.Using immunohistochemistry method,the expression of EGF-R of lung tissues in different groups was observed,and the expression of EGF mRNA was determined by reverse transcriptase polymerase chain reaction(RT-PCR).RESULTS:The expression of EGF mRNA increased by degrees following the increasing postnatal days.Compared with the air control group,the expression of EGF-R and EGF mRNA increased in the hyperxia group at 7th day and 14th day.The expression of EGF-R increased in corresponding hyperxia NS control group at 14th day(P

Objective To establish a new T staging system for nasopharyngeal carcinoma ( NPC) based on magnetic resonances imaging ( MRI) and intensity?modulated radiotherapy ( IMRT) . Methods A retrospective analysis was performed on the clinical data of 608 patients who were newly diagnosed with non?metastatic NPC by MRI and treated with IMRT in our hospital from 2008 to 2010. All patients were staged according to the 7th edition of the UICC/AJCC staging system for NPC. The survival rates were calculated using the Kaplan?Meier method and analyzed using the log?rank test. The Cox regression model was used for multivariate analyses. To deal with the deficiency in the current UICC/AJCC staging system, a new T staging system for NPC was established and systematically evaluated. Results The 5?year follow?up rate was 94?5%. The 5?year overall survival (OS), disease?free survival, local relapse?free survival (LRFS), and distant metastasis?free survival rates were 81?5%, 80?1%, 86?0%, and 81?1%, respectively. The univariate and multivariate analyses showed that the anatomic structures of nasopharynx, parapharyngeal space, and skull base were influencing factors for the OS rate (P=0?000?0?045). New T staging criteria were proposed based on the risk differences and survival curves:stage T1:invasion of the nasopharynx, parapharyngeal space, oropharynx, nasal cavity, skull base, and internal pterygoid muscle;stage T2:invasion of the external pterygoid muscle, paranasal sinus, intracalvarium, infratemporal fossa, and cranial nerves. The proposed T staging system achieved a good separation in both OS and LRFS curves. Conclusions The proposed new T staging system gives an objective prognostic prediction in patients with NPC, which provides an exploratory attempt toward a new clinical staging system for NPC.

ObjectiveTo systematically evaluate the efficacy and safety of glycyrrhizin in patients with chronic severe hepatitis B. MethodsLiterature published from January 1990 to July 2014 were searched in databases including PubMed, Cochrane Library, CBMdisc, CNKI, VIP, and Wanfang Data. The randomized controlled trials comparing the efficacy of glycyrrhizin combined with internal comprehensive therapy versus internal comprehensive therapy alone in patients with chronic severe hepatitis B were included in the analysis. The methodological quality of included trials was independently assessed and the data were extracted. Meta-analysis was carried out with Review Manager Software 5.1, and the heterogeneity, sensitivity, and bias of the analysis were evaluated. ResultsSeven randomized controlled trials involving 298 patients in the test group and 294 in the control group were included in the analysis. The results of meta-analysis showed that glycyrrhizin combined with internal comprehensive therapy was remarkably more effective than internal comprehensive therapy alone, indicated by significantly reduced mortality rate ［relative risk(RR)=0.56, 95% confidenceinterval(CI):0.42~0.76, P＜0.01］, significantly decreased level of total bilirubin (TBil) ［mean difference(MD)=-92.56, 95%CI:-122.92~-62.20, P＜0.01］, and significantly higher prothrombin activity (PTA) ［mean difference(MD)=11.14, 95% CI:5.40~16.87, P＜0.01］. No severe adverse reactions were found in all patients. ConclusionGlycyrrhizin can significantly reduce the mortality and improve TBil and PTA in patients with chronic severe hepatitis B.

This paper is mainly devoted to the relationship between the correlation dimension (CD) of exercise heart rate variability (EHRV) and the status of cardiovascular function. Hypertensive patients and healthy people were enrolled in two contrast groups. Dynamic electrocardiograph (ECG) in step exercise was recorded. EHRV was extracted by wavelet transform. The CDs in the whole course of exercise and in three stages of exercise were calculated, the three stages being named rest-before-exercise, during-exercise, and after-exercise. SPSS software was used for statistical analysis. The results revealed all the CDs showed significant difference between two groups except that in the stage of during exercise. By discrimination analysis, the average correct rate was 92.2%. It indicated that the CD in stress status probably could be an effective non-linear parameter for assessing cardiovascular function status.

Objective: To survey the prevalence of drug resistant HIV-1 in Shandong province in 2013-2015. Methods: WHO truncated sequential sampling technique was adopted by using 77 and 53 samples of newly diagnosed as HIV-1 positive and aged 16-25 years in Shandong province in 2013 and 2015. RNA was prepared and HIV-1 pol region was amplified by RT-PCR and nested PCR. Pol genetic mutation associated with drug resistance was analyzed. Results: The success rates for sequence acquisition of the survey were 100% (77/77) and 94% (50/53) in 2013 and 2015, and the main subtype was CRF01_AE. A total of 2 surveillance drug-resistance mutation(SDRMs) and 3 SDRMs were found by analyzing the 47 sequences each year, sampled in 2013 and 2015, indicating that the prevalence of drug resistant HIV-1 stains was low in 2013, and moderate in 2015. A total of 5 individuals with drug resistant HIV-1 stains found in this study were mainly infected by homosexual transmission (3 cases), and the other two samples were different: one was infected by heterosexual transmission, the other was infected by IDU. The subtype was CRF01_AE (2 cases) , CRF07_BC (2 cases) and B (1 case) . SDRMs for protease inhibitor (PIs), nucleotide HIV-reverse transcriptase inhibitor (NRTIs) and non-NRTI (NNRTIs) were all found in the individuals with drug resistant HIV-1 stains. Conclusion CRF01_AE were the main HIV-1 subtypes of recently reported HIV-infected individuals in Shandong province, and the HIV-1 drug resistant strains transmission was catalogued as at low and moderate prevalence level in 2013 and 2015.
