The effects of continuous occlusion of thoracic or abdominal aorta (OTA or OAA) via intra-aortic balloon inflation on coronary perfusion pressure (CPP) were observed in 12 dogs after 10 min of cardiac fibrillation in comparison with those of different doses of epinephrine (0.02~0.14 mg/kg). The results showed that OTA could not increase CPP. However, during 30 min of cardiopu-Imonary resuscitation(CPR), every 3 min of OAA was followed by markedly increased CPP, 067 ~ 12kPa higher than the value in balloon deflation peritxl right before(P

Objective To analyze catheter-related bloodstream infections due to Rhizobium radiation (R.radiobacter) in pediatric patients.Methods Clinical data of 1 014 pediatric patients with intravascular catheterization were collected from February 2012 to February 2014,including age,length of time a catheter remained in place,laboratory findings and outcome of R.radiobacter bloodstream infection in order to explore the factors for R.radiobacter infection.Results There were 26 children contracting R.radiobacter bloodstream infection children,and of them,21 were under 2 years old (80.77％),and the length of time for catheter dwelt in vessel longer than 5 days in 20 children (76.92％).There were significant differences in age under 2 years old,length of time longer than 5 days for catheter remained in place,CD4 and CD4/ CD8 between 26 children with R.radiobacter infection and uninfected children (P ＜ 0.01).The re-infection with different varieties of bacterial strains was found in 12 of all R.radiobacter infection children (46.15％) after treatment,and of them,R.radiobacter bloodstream infection was detected twice in 2 children,and 2 died (7.69％).Conclusions Age under 2 years old,the length of time for intra-vascular catheter remained in place longer than 5 days,and weakened immunity are the important risk factors of R.radiobacter bloodstream infection,and the improper medical care may be the cause of re-infections in pediatric patients with prolonged intra-vascular catheter-dwelling.

ObjectiveTo investigate the incidence and risk factors of antibiotic-associated diarrhea (AAD) of pediatric patients with severe bacterial pneumonia.MethodsClinical data of 1086 pediatric patients with severe bacterial pneumonia from January 2010 through January 2014 were recruited. The incidence and risk factors of AAD were retrospectively analyzed. ResultsThe incidence of AAD in 1086 pediatric patients with severe bacterial pneumonia was 36.74%. The incidence of AAD in patients younger than 2 years old were higher than that in those older than 2 years, once or more times of mechanical venti-lation history were higher than that with no arrangements of this treatment, administering of combined antibiotics therapy were higher than that with single antibiotics, and the incidence of AAD due to amoxicillin/clavulanate, piperacillin/tazobactam, cefo- perazone/sulbactam in pediatric patients were 43.55%, 43.75%, and 45.03%, respectively. Three β-lactam/β-lactamase inhibitors above were risk factors of AAD through multivariate Logistic regression analysis.ConclusionThe high incidence of AAD in pediatric patients with severe bacterial pneumonia was associated with some risk factors, including younger than 2 years old, me-chanical ventilation, combined antibiotics therapy and administration of β-lactam/β-lactamase inhibitor (amoxicillin/clavulanate, piperacillin/tazobactam, cefoperazone/sulbactam).

(P > 0. 05). Conclusions:Metronidazole-containing triple therapy may reduce the CD infection secondary to eradication of Hp infection in pediatric patients,and has no negative impact on efficacy of Hp eradication.

OBJECTIVETo analyze the incidence and treatment of Clostridium difficile infection (CDI) in pediatric patients with antibiotic-associated diarrhea (AAD).

METHODClinical data of totally 577 pediatric patients with AAD seen from January 2012 to January 2014 were collected; those children were divided according to age into 4 groups, 0.25 -1 year, >1 -4 years, >4 -12 years and >12 -18 years old groups, and 220 healthy children were enrolled as controls. CDI was tested by C. Diff Quik Chek Complete (QCC) and BD GeneOhm™ C. Diff Assay (BD-PCR) in all children, and the CDI incidence of four groups was added up. All pediatric patients with AAD were divided into mild, general and severe type according to different symptoms of diarrhea, and grading treatment, the general type and severe type of CDI children were treated with metronidazole and (or) vancomycin, afterwards, the results of grading treatment were analyzed.

RESULTThe number of pediatric patients with AAD were 178, 177, 132 and 90 in 0. 25 - 1 year, > 1 -4 years, > 4 - 12 years and > 12 - 18 years old group, respectively. The positive rate of CDI (22. 0% (39/177)) in > 1 -4 years old AAD patients was very significantly higher compared to the controls (4% (4/91), P < 0. 001), the rate of CDI (21. 2% (28/132)) in > 4 - 12 years old AAD pediatric patients was significantly higher compared to the controls (4% (2/53), P = 0. 004), the rates of CDI in 0. 25 - 1 year and > 12 - 18years old AAD groups were not significantly different from that of the controls (P >0. 05). There were 285 mild type AAD children (no CDI children), 176 general type AAD children (including 47 CDI children), and 116 severe type AAD children (including 81 CDI children). After grading and symptomatic treatment, there were 16 recurrent diarrhea in 128 CDI patients (severe type AAD), and the rest recovered. Two cases were transferred for referral treatment, 2 cases died, and the rest 12 recurrent diarrhea children fully recovered after administration of metronidazole, vancomycin, probiotics and symptomatic treatment.

CONCLUSIONThe > 1 -12 years old AAD children had higher CDI rate than healthy children; administration of metronidazole and (or) vancomycin was effective for CD infection.

Objective: To evaluate comprehensive health status of 31 provinces in China and compare with other countries (regions). Methods: Social-demographic index, life expectancy and healthy life expectancy in 134 countries (regions) and 31 provinces in China were collected from the Global Burden of Disease Study 2015. K-means clustering method was used to classify comprehensive health status of various countries (regions) in the world. HemI 1.0.3 software was applied to draw distribution heat maps of social-demographic index, life expectancy and healthy life expectancy in different provinces of Mainland China. Discriminant analysis was used to evaluate comprehensive health status of different provinces in Mainland China. Results: Comprehensive health status of 134 countries (regions) was grouped into category 1-8 from good to poor, and Mainland China was in the category 4. The comprehensive health status of provinces in Mainland China is better in the east coast and poorer in the west inland, among which Shanghai and Beijing were grouped into the category 1, Zhejiang, Jiangsu, Guangdong and Tianjin into the category 2, Fujian, Liaoning and Shandong into the category 3, Yunnan, Guangxi, Xinjiang and Guizhou into the category 5, Qinghai and Tibet into the category 6, and the rest 16 provinces into the category 4. Conclusion Comprehensive health status of Mainland China ranked middle to upper level in the world, and health status disparities were observed among different provinces in Mainland China.
