Objective To investigate the expression and significance of interkeulin 10 (IL-10)in children patients with mycoplasma pneumoniae pneumonia(MP). Methods Twenty-six children patients with MP( MP group)and20 health control( contrl group)were sequentially enrolled in this study. The production of IL-10 mRNA was measured by fluorescent quantitative polymerase chain reaction. Results Expression of IL-10 mRNA in MP group (33 893.22±5 207.60) copy/μg was significantly lower than that in control group(59 341.92 ±6 712.98) copy/μg(t = - 14. 49, P ＜ 0. 01 ). Expression of IL-10 mRNA in heavy degree MP group was significantly lower than that of mild degree MP group ( t= - 2. 20, P ＜ 0. 05 ). Conclusion The expression of IL-10 was low, and played an important role in the development of patients with MP.

Objective To explore the molecular types of methicillin-resistant Staphylococcus aureus (MRSA) strains present in major hospitals in Qingdao area, using pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) methods, trying to find out the epidemiological characteristics of these MRSA isolates. Correlation of the PFGE types with microbiological phenotypes and clinical data was also studied. Methods 360 isolates of MRSA were procured during 2003 to 2007 from major hospitals in Qingdao. PFGE technology was applied to comparatively analyze the chromosomal DNA digested with endonuclease Sma Ⅰ . Comparison of DNA fragments patterns from each MRSA strain and cluster analysis were performed with the Bionumericus version ' 2.0' software. A dendogram was generated using PFGE macrorestriction fragments on gel images. Data was used to predict the possibility of each PFGE type via SPSS software version 11.0, using the variables as predictors including groups on patient's age, gender, source and the site where MRSA was isolated. Antibiotic sensitivity patterns of these MRSA isolates were determined by K-B tests, and a correlation between these patterns and PFGE types was investigated. Housekeeping genes were amplified with PCR and sequenced in representative strains of variant PFGE types to identify their allelic profile. Results 5 types of PFGE patterns (M0-M4) were identified with MI being the predominant and M2 next to it which was significantly correlated to the isolates from wounds. M3 type strains were mainly isolated from ICU wards and there were a few cases complied with M4 type with no correlated variant factors found in this study. A unique pattern of MRSA isolates with its M0 distinct from other types had not been reported. No significant association was found between PFGE individual types,gender or age groups. M1 and M2 types were the major proportional PFGE patterns among different hospitals. No vancomycin-resistant isolates were detected among 360 MRSA strains. No significant association was found between individual antibiotic resistance and specific PFGE types. Data from MLST analysis showed that the aUelic profiles of M1 and M3 type strain had the same ST239 linage which was commonly present in China. For M2 and M4 representative strains, the allelic profiles were ST5 and ST240, respectively. ST45 and ST398 were corresponding to two PFGE patterns clustered as M0 type. Conclusion Nosocomial infection due to MRSA was evenly distributed among different age groups and no gender bias was observed. The PFGE types of MRSA strains isolated in major hospitals in Qingdao were highly correlated with the sources of isolates and ST239 isolate seemed the prevalent and widespread one. Strategies should be designed to further monitor and prevent or minimize the spread of ST5 MRSA isolates and the like, in Qingdao area.

Objective To investigate the effect of comprehensive intervention therapy of reducing fat on sex hormone and growth hormone(GH) in adolescent girl students with simple overweight and obesity.Methods Girl students with simple obesity were accepted a comprehensive measures composed of aerobicexercise,reasonable diet,behavior modification for 10 monthes,and their sex hormone and GH were detected and analyzed before,during and after test respectively.Results GH and estradiol(E_2) levels were significantly lower in obese subjects than those in normal subjects,but the level of testosterone(T) was highter,and GH and E_2 were increased obviously after reducing fat.Level of T decreased significantly(P

Objective:To search, evaluate and integrate the best evidence for lactation maintenance of very low birth weight infant(VLBWI) mothers, and to provide evidence for lactation maintenance.Methods:Up to Date, BMJ best practice, Newborn Services Clinical Guidelines, ABM, NICE, OVID evidence-based database, NGC, Joanna Briggs Institute Library, Cochrane Library, Web of Science, PubMed, CNKI, CBM and Wanfang Data were retrieved by computer on the Maintenance of Mother′s Lactation in VLBWI: Guidelines, Systematic Evaluation, Expert Consensus/Opinions, Evidence Summary Literature screening, quality evaluation, evidence extraction and integration of documents which met the requirements.Results:A total of 10 articles were included, including 3 guidelines, 4 systematic reviews, 1 expert consensus and 2 expert opinions. A total of 41 evidences were summarized from 9 aspects, including lactation support, lactation initiation, lactation monitoring and the application of lactating agents.Conclusion:The evidence of lactation maintenance of VLBWI mothers is sufficient, which can provide a basis for medical staff to make clinical decisions.

By organizing literature, summarizing and analyzing the relevant experimental and clinical studies, this article analyzed the study status of the analgesic action of electroacupuncture with different frequencies from the chemical mechanism, neuro- physical mechanism, molecular mechanism, and action mechanism. It brought up that electroacupuncture of different frequencies can activate different regions in the central system and generate different central opioid peptides, excite different receptors and afferent neurons, and different acupuncture manipulations can induce different neural electrical information encoding sequences. This article has provided theoretical evidences for future researches on the mechanism of acupuncture analgesia.
