Objective To study common Gram negative bacterial pathogens and their drug resistant pattern in sputum isolates from patients in pediatric intensive care unit (PICU) of Chengdu children' s hospital. Methods Comparing to the period of 2004-2006 with 2007-2009, we retrospectively reviewed eligible sputum isolates of common Gram negative bacilli and their drug resistance pattern. All specimens were processed according to standard microbiological methods for both quantitative and qualitative cultures. Pathogen was the single predominant growth after two consecutive cultures. Strict quality control was used in all test agents and paper disk for drug resistance analysis. Results Total of 598 Gram negative bacterial isolates were identified in patients over 6 years. The first 5 bacteria respectively were Escherichia coli 167 samples(27.93%), Klebsiella pneumoniae 109 samples ( 18.23% ), Enterobacter cloacae 93 samples ( 15.55% ),Acinetobacter baumannii 64 samples ( 10. 7% ), Pseudomonas aeroginosa 43 samples (7. 19% ). They were mostly sensitive to Imipenam, Amikacin, Piperacillin/Tazobactam. Most drug resistance rate was found in Amoxicillin, Ampicillin, Cephalosporin. Apart from Pseudomonas aeroginosa and Acinetobacter Baumannii,no Gram negative bacteria was found to be resistant to Imipenam. Klebsiella pneumoniae and ESBL secreting Escherichia coli isolates were obviously increasing when compared to 3 years ago. Conclusion Comparing the period of 2004-2006, the Gram negative bacterial isolates were increasing in our PICU patients during 2007 to 2009. Close monitoring of drug resistance pattern changes in PICU would guide rational use of antibiotics in these critically ill children.

Purpose To investigate the diagnostic value of gray-scale ultrasound on ovarian cystic teratoma.Materials and Methods 83 patients with primary diagnosis of ovarian cystic teratoma underwent gray-scale ultrasonography. The ultrasonic images were compared with postoperative pathologic results. Results 91 cases of 83 lesions were detected. The ultrasonic features were categorized into 6 types: cystoid, solid-like, intracystic dough sign, intracystic hair-ball, intracytic fat-fluid level, and intracytic cluttering sign. The diagnose accordance rate for each sign was 81.0%, 77.8%, 96.2%, 100% and 70.0% respectively. The diagnose accordance rate of ultrasonic diagnosis compared with pathologic results was 89.0% (81/91), and misdiagnosed rate and rate of missing diagnosis was 11.0% (10/91). Conclusion The ultrasonic features of ovarian cystic mature terotoma were of importance diagnostic value, whereas differentiation with ovarian chocolate cysts and ovarian mucus-cystic adenoma should be made cautiously.

South Africa is an ethnically and culturally diverse presidential republic country. The medical and health system consists of public and private medical care. AIDS, lower respiratory infections, neonatal diseases, and interpersonal violence and road injuries are the leading causes of adult death. South Africa has rich herbal resources, and a long history of traditional medicine, which is mainly black African traditional medicine. Until the establishment of diplomatic relations between China and South Africa in 1998, the development of TCM was significantly improved, and legislation of TCM was adopted by the government in 2000. Chinese herbal medicine has not yet formed industrial standardization, the TCM application and TCM education are insufficient. Therefore, it is suggested to accelerate the standardization of TCM, to strengthen the TCM education for professional TCM practitioners, and to form a large-scale, industrial and standardized development model. Only in these ways can TCM provide good medical services for residents in South African.

Objective:To investigate the clinical value of serum miR-208a in early differential diagnosis of acute coronary syndrome(ACS).Methods:One hundred ACS patients admitted to our department from January 2016 to January 2018 were randomly divided into the non-ST elevation myocardial infarction(NSTEMI)group(n=50)and the unstable angina(UA)group(n=50). Fifty healthy people during the same period were included as the control group(control). Serum levels of miR-208a, cardiac troponin-T(cTnT)and creatine kinase MB isoenzyme(CK-MB)were detected immediately, 4 h, 12 h and 24 h after admission and compared among the three groups of NSTEMI, UA and control.Receiver operating characteristic(ROC)curve was used to analyze the early diagnostic value of above serum indexes in NSTEMI and UA group, and the correlations of miR-208a level with cTnT and CK-MB were analyzed.Results:Serum miR-208a and cTnT levels had significant differences( P<0.05), while serum CK-MB level had no significant difference( P>0.05)among the NSTEMI and UA groups immediately after admission and the control group in the fasting state.There were significant differences in serum miR-208a, cTnT and CK-MB levels between NSTEMI group and UA group at different time points( P<0.05). After further multiple comparisons, the results showed that serum miR-208a and cTnT levels had statistical differences( P<0.05)and serum CK-MB level had no difference( P>0.05)between the NSTEMI group and the UA group immediately after admission.The above three biochemical indexes showed statistically significant differences between the NSTEMI group and the UA group at 4 h, 12 h and 24 h after admission( P<0.05). ROC curve analysis showed that miR-208a had a high diagnostic value in ACS(AUC>0.9, P=0.004), and the best diagnostic cut-off point was 9.278.The cTnT had a medium diagnostic value in ACS(0.7

Objective To investigate the exposure level of radioactive hazard factors and the health management of radiation workers in non-medical radiation institutions (excluding military institutions) in Jinan, China through radioactive hazard factor monitoring, to identify the weak links, and to provide a scientific basis for future work priorities. Methods According to the monitoring plan formulated by Jinan Municipal Health Commission, the task undertaking institutions at all levels in Jinan investigated the types of radioactive hazard factors, detection, training, and health monitoring of 101 non-medical radiation institutions in Jinan. In addition, the workplace radiation levels were detected in 25 institutions of 6 types of monitoring objects, including industrial flaw detection, non-medical accelerator, non-sealed radioactive material workplace, nuclear instrument, baggage detector, and others. Results The investigation objects included institutions engaged in industrial flaw detection, nuclear instrument, luggage detector, non-medical accelerator, non-sealed source workplace, and others. Of these institutions, 91.84% were equipped with radiation protection detectors, 92.86% were equipped with personal dose alarm, 97.73% were equipped with personal protective equipment, 94.36% performed radiation protection training, 92.69% employed radiation workers with certificates, 95.77% performed personal dose detection, 94.83% performed occupational health examination, and 100.00% were qualified for radiation protection detection in workplace. Conclusion There is still a gap between the radiation protection status of non-medical institutions in Jinan and the national regulations and standards, so it is necessary to further strengthen supervision and law enforcement and make greater efforts in training and publicity.
