目的 了解广东地区糖尿病足患者创面病原菌分布及耐药性变迁。方法 回顾性分析A组(2010年1月—2014年12月就诊的糖尿病足患者)和B组(2015年1月—2018年1月就诊的糖尿病足患者)研究者创面病原菌分布及耐药性变迁。结果 B组中创面G⁺菌及G^-菌均有下降趋势且G^-菌下降较快,细菌种类明显增加,真菌及混合感染明显上升,A组以金黄色葡萄球菌、铜绿假单胞菌、大肠埃希菌感染为主;B组以金黄色葡萄球菌、奇异变形杆菌、铜绿假单胞菌及真菌感染为主;B组相对于A组的细菌耐药性增加。结论 近年来糖尿病足患者病原菌种类明显增加且混合感染及真菌感染上升,且其耐药性增加,因此早期经验用药而后根据药敏选择抗菌药物治疗是糖尿病足感染治疗的关键。

Objective To investigate the distribution and drug resistance of pathogenic bacteria in diabetic foot wounds in Guangdong area. Methods Patients with diagnosis of diabetic foot between group A (from Jan 2010~Dec 2014 ) and group B (from Jan 2015 to Jan 2018) were retrospectively analyzed. We studied the bacteria distribution and drug resistance of pathogenic changes of group A and group B. Results In group B, both G+ and G- bacteria had a decreased trend while G- bacteria decreased rapidly, but the species of bacteria increased obviously just as fungi and mixed infection increased obviously. Bacteria infection in group A were mainly about Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli wihle group B were Staphylococcus aureus, Proteus mirabilis, Aeruginosa and Fungal infection; the resistance of group B to A was lower. Conclusion In recent years, kinds of pathogenic bacteria of diabetic foot were significantly increased and the mixed infection and increased fungal infection as well as its drug resistance increased, so the early experience of medication choice of antibiotics based on drug sensitivity and treatment are the key to the treatment of diabetic foot infection.

目的 分析雷替曲塞致药品不良反应(ADR)的特点及相关因素影响,为临床用药提供参考依据。方法 以“雷替曲塞”、“不良反应”、“raltitrexed”等为检索词,在中国期刊网全文数据库(CNKI)、维普中文期刊数据库等检索近5年的文献,共纳入符合标准文献28篇进行整理,分析雷替曲塞所致ADR类型及在不同给药剂量、联合化疗或同步放疗及老年患者、特殊给药途径下ADR发生的特点。结果 雷替曲塞常见的ADR包括消化系统症状、中性粒细胞减少和转氨酶升高,而中性粒细胞减少和转氨酶升高对临床治疗影响较大。给药剂量对ADR影响较小,而联合放疗会增加骨髓抑制的风险;在两药联合化疗时,雷替曲塞与长春瑞滨联合致中性粒细胞减少的风险增加;雷替曲塞引起的转氨酶升高多为Ⅰ~Ⅱ级,高龄(≥70 a)、肝转移对转氨酶升高影响不大。结论 雷替曲塞在不同治疗方案中的ADR发生存在差异,临床应用时应注意监测,防范严重和罕见ADR的发生。

Objective To Summarize the literature on adverse drug reactions(ADR) of Raltitrexed,in order to provide reference for the rational use of the drug in clinic. Methods Raltitrexed and adverse reaction were both used as key words to retrieve articles in CNKI and VIP database, 28literatures which met the inclusion and exclusion criteria were collected and analyzed. The characteristics of ADR were analyzed indifferent dosage, combined chemotherapy or radiotherapy, elderly patients and using with special administration. Results The main adverse reactions of Raltitrexed in the treatment included digestive system symptoms, neutropenia and elevation of aminotransferase, and the latter two had a great influence on the clinical treatment.Combination with radiotherapy increased the risk of myelosuppression. Incidence of neutropenia in combination Raltitrexed with Vinorelbine was higher. Transaminase elevations were generally Ⅰ-Ⅱ grades. Age(≥70 a) and liver metastasis had little effected on transaminase increase. Conclusion There were differences in the occurrence of ADR in different therapeutic schemes. Attention should be paid to ADRs of Raltitrexed especially to monitoring and reporting rare and severe ADRs in clinic.

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.
