目的 了解中山市7家医院金黄色葡萄球菌感染的临床分布,并对耐药基因进行检测,为临床经验治疗金黄色葡萄球菌感染提供用药及分子生物学依据。方法 收集2015年1月—2015年6月中山市7家医院分离到的金黄色葡萄球菌,使用ATB半自动细菌鉴定及药敏分析仪(法国梅里埃)对分离到的菌株进行鉴定及药敏试验,使用PCR技术对耐甲氧西林金黄色葡萄球菌(MRSA)的耐药基因进行检测。结果 7家医院共分离到89株金黄色葡萄球菌,其中MRSA检出33株,检出率为37.1%。金黄色葡萄球菌主要来源于呼吸内科(32株,36.0%)、骨科(20株,22.5%),主要分离自痰(41株,46.1%),伤口分泌物(16株,18%),对万古霉素、替考拉宁、奎奴普丁/达福普丁、复方新诺明、左氧氟沙星、诺氟沙星具有较高敏感性,MRSA对常用抗菌药物耐药率高于甲氧西林敏感金黄色葡萄球菌。共有32株MRSA检出bla_mecA基因,检出率为97%。结论 MRSA耐药情况较为严峻,临床科室应根据微生物培养报告合理使用抗菌药物。bla_mecA基因在MRSA检出较高,是MRSA主要的耐药机制。

Objective To analyze clinical distribution of Staphylococcus aureus infections from 7 hospitals in Zhongshan city, as well as to provide basis of empirical treatment and molecular biology for Staphylococcus aureus infections. Methods Staphylococcus aureus were collected from January 2015 to June 2015 in Zhongshan city, and then the strains were identified and tested antibiotic susceptibility by using ATB semiautomatic analyzer(Merieux). Resistance gene of methicillin-resistant Staphylococcus aureus(MRSA) was detected by polymerase chain reaction. Results 89 strains of Staphylococcus aureus were isolated from 7 hospitals and with prevalence of 33 strains of MRSA. Of all strains, 32(36.0%) were isolated from respiratory medicine and 20(22.5%) from orthopedics. 41(46.1%) strains of Staphylococcus aureus were isolated from sputum and 16(18.0%) from wound secretion. 89 strains of Staphylococcus aureus had highly susceptibility to vancomycin, teicoplanin, quinupristin/dalfopristin, cotrimoxazole, levofloxacin, norfloxacin. Resistance rates to commonly used antimicrobial drugs of MRSA were significantly higher than methicillin-sensitive. A total of 32 MRSA were detected carrying bla_mecA gene with the detection rate of 97%. Conclusion Clinical departments should be based on microbial culture report for rational use of antibiotics because of MRSA with more serious drug resistance. The gene of bla_mecA is the main mechanism of resistance for MRSA.

目的 探讨糖尿病胃轻瘫大鼠不同血糖水平对Cajal间质细胞(ICC)的影响及其机制。方法 选择雌性Wista大鼠60只进行随机分组,实验组40只,对照组20只。实验组糖尿病Wista大鼠模型以单次腹腔注射链脲佐菌素法诱导。免疫组织化学荧光染色检测不同血糖浓度大鼠胃ICC数量及网络结构。结果 实验组大鼠血糖浓度高于对照组,ICC数量,低于对照组,且比较差异有统计学意义(P<0.05)。实验组大鼠中血糖浓度越高,ICC数量越低,说明血糖浓度升高可能与平滑肌及神经末梢之间缝隙连接的减少及其ICC网络的超微结构损伤及异常有关。结论 DM小鼠胃组织中血糖水平的升高,可能是DM胃中ICC数量减少的原因;外源性降低血糖能改善DM相关的胃肠道ICC病变。

Objective To observe the effects of glucose fluctuations on Cajal interstitial cells (ICC) of rats with diabetic gastroparesis(DGP) and its mechanistic. Methods 60 Wistar rats were selected and randomly divided into two groups. 20 rats in experimental group and 40 rats in control group. Used immunofluorescence staining to detect the amount of gastric ICC and network structure in DGP rats with different glucose levels. Results The blood glucose concentration in the experimental group was significantly higher than that in the control group, the amount of ICC in the experimental group was significantly lower than that in the control group(P<0.05). The amount of ICC decreased with the increase of glucose levels. In the experimental group, The gap junctions between smooth muscle and nerve endings, ultrastructural damage and abnormalities of the ICC network were probably related to glucose level. Conclusion The increase of glucose level was probably the cause of the decrease of the amount in ICC. Exogenousy decrease glucose levels probably can help to improve the lesion of ICC with DGP.

Objective To investigate the associations between different time and types of intrauterine device with female reproductive tract infection in order to provide evidence for reducing infection rate. Methods 360 females using intrauterine device were continually recruited during Jan 2013-Jan 2015 in our hospital, and their clinical data was also collected in the same period. The associations between reproductive track infection and clinical characteristics including service time, types, age, gravidity and menopause status were further analyzed. Results We found that the female using intrauterine device with tail wire, as well as with non-menopause had higher infection risk than those did not have(P<0.05). In addition, service time of intrauterine device was significantly associated with infection risk in those patients using intrauterine device with tail wire. However, there was no any remarkable relevance for age and gravidity with risk of reproductive track infection. Conclusion The use of intrauterine device with tail wire, as well as longer service time, could cause the increased risk of reproductive track infection for females.
