ObjectiveThe clinical features, bacteria distribution and antibiotic resistance proifle of blood stream infection(BSI) were investigated in the patients with decompensated liver cirrhosis for better management of such infections.MethodsThe clinical data of BSI were collected in the patients with decompensated liver cirrhosis between January, 2012 and December, 2014, and reviewed retrospectively in terms of risk factors, diagnosis and treatment, pathogen distribution and prognosis.ResultsOf the 1 071 patients with decompensated liver cirrhosis and suspected bacterial infection, 154 (14.4%) were diagnosed as BSI evidenced by blood culture. Of these patients, the leukocyte count in the peripheral blood was higher than 10×109/L in only 48 (31.2%) patients; neutrophil proportion>0.75 in 133 patients (86.4%); serum procalcitonin level>0.5 ng/mL in 74 patients (68.5%). A total of 155 bacterial strains were isolated, including 115 strains of gram-negative bacilli and 40 strains of gram-positive cocci. Most patients (68.8%) recovered and 31.2% died or discharged from hospital voluntarily. All these BSI patients had Child-Pugh grade C liver function. Some patients also had other serious systemic diseases or repeated hospitalization.ConclusionThe prevalence of BSI is high in the decompensated liver cirrhosis patients with poor prognosis. Gram-negative bacilli are the major pathogens of such septicemia. Early diagnosis and proper use of antibiotics based on antimicrobial susceptibility testing are important to improve patient outcome.

To implement the excellent doctor education training plan and construct the training model of practical ability in clinical education,the researchers analyzed the problems existing in the training of clinical practice ability and put forward a new train of thought,and constructed a training method system of personal experience,reading classics,teacher guidance,simulation training,clinical practice and reflection strengthening.In addition,we also established a safeguard mechanism with the characteristics of the organizational corporation of teaching,the expert-oriented teaching team,team-oriented mentoring,pro-ject-oriented ability training,the diversification of evaluation system,the modernization of teaching platform and the realistic training environment,to train the qualified clinical medical talents.

Objective To analyze the spatial clustering of human schistosomiasis at the village level in key counties in Hubei Province, to provide scientific evidence for formulating strategies for human schistosomiasis prevention and control in the next stage. Methods Gong^'an County and Jiangling County in Hubei Province were selected as representative counties for this study. A town or village was set up as a research unit. Schistosomiasis cases of a positive fecal examination in 2015 and cases with positive detection for schistosomiasis serological antibody titer equal or above 80 in 2016-2018 were selected as research subjects in these two counties. The Kulldorff circular scan statistic was used for the spatial clustering analysis of human schistosomiasis infection status in the population. Results There was spatial clustering of positive schistosomiasis cases of fecal examination, at the level of a town or village in both counties in 2015. There was spatial clustering of positive human serological antibody detection at the level of town or village from 2016-2018. Eighty-six endemic villages in five towns in the northeast of Gong^'an County, along the Yangtze river,including Mahaokou Town, Zhakou Town, Yangjiachang Town, Jiazhuyuan Town and Douhuti Town, were the most prominent. There was no spatial clustering of positive results of human serological antibody detection at the town and village level in Jiangling County, in2017, while there was spatial clustering of human serological antibody detection in 2016 and 2018,respectively. Fifty-seven endemic villages in two towns (Puji Town and Xionghe Town) in the southwest of Jiangling County, along the Yangtze river,were the most prominent. Conclusion There were spatial clustering of human schistosomiasis epidemic at village level both in Gong^'an County and Jiangling County, Hubei Province. Compared with the previous studies, there was a trend of shrink and decline of clustering areas. Therefore, the current situation of the epidemic has put forward higher requirements for the implementation of precise prevention and control in the progress of schistosomiasis elimination work in various epidemic areas.
