目的 对86例青春期多囊卵巢综合症(polycystic ovary syndrome,PCOS)患者进行随访,探讨患者长期治疗的依从性。方法 选择2009年11月—2012年6月在我院门诊首次诊断为青春期PCOS患者进行前瞻性队列研究。按随诊方法不同分为常规随访组和可及与连贯病人服务(ACC)组,前瞻随访6个月。分别在初次就诊时、3个月及6个月后对比两组的身体质量指数(Body Mass Index, BMI)、复诊率和遵医嘱服药率。结果 共86名患者入组,其中常规随访组43人,ACC组43人。两组基线资料基本一致。随访3月时,两组的BMI、复诊率和遵医嘱服药率的差异无统计学意义(P>0.05)。随诊6月时,ACC组的复诊率和服药依从性均优于常规随访组分别为(97.7% 比 81.4%,97.7% 比 76.7%,P＜0.05),BMI比常规随访组下降(22.33±7.31 比 24.59±7.8 kg/m²,t<0.05)。结论 可及与连贯的病人服务可以改善青春期PCOS患者BMI及长期随诊的复诊率和服药依从性。

Objective To investigate the compliance of adolescent patients with polycystic ovary syndrome (PCOS) in long-term treatment by access to care and continuity of care(ACC) on 86 cases. Methods A prospective cohort study was taken for 6 months on adolescent patients diagnosed as PCOS for the first time in out-patient department from November 2009 to June 2012. These patients were selected and divided into ACC group and regular follow-up group according to the different modes of follow-up visit. The relevant data including body mass index (BMI), clinic visit rate and rate of medication adherence were compared in the first visit and 3rd, 6th month in the follow-up visit. Results 86 patients were enrolled with 43 in ACC group and 43 in regular follow-up group. The baseline information was similar between the two groups. There were no statistically significant difference between groups in BMI, clinic visit rate and rate of medication adherence after 3 months (P>0.05). However, after 6 months, BMI, clinic visit rate and rate of medication adherence were significantly improved in the ACC group compared to the regular follow-up group (22.33±7.31 vs 24.59±7.8 kg/m², 97.7% vs 81.4%, 97.7% vs 76.7%, P＜0.05, respectively). Conclusion ACC could improve BMI, clinic visit rate and medication adherence of adolescent patients with polycystic ovary syndrome in long-term treatment.

Objective To investigate the molecular characteristic of Community-acquired Methicillin-resistant Staphylococcus aureus(CA-MRSA) isolates from pediatric patients in Guangzhou. Methods 65 non-duplicate strains of Community-acquired Methicillin-susceptible Staphylococcus aureus(CA-MSSA) isolated from our hospital in 2009-2014 were investigated. Panton-valentine leukocidin(PVL) gene was detected by polymerase chain reaction(PCR). The sequence type (ST) of each strain was determined by muhilocus sequence typing (MLST). The genotypes of staphylococcal cassette chromosome mec(SCCmec) of the CA-MRSA isolates were confirmed by multiplex PCR. Results Among 65 isolates of CA-MRSA, the positive rate of PVL genes was 47.69%(31／65). The most common MLST type was ST59 (n=22, 33.84%), followed by ST88 (n=15, 23.07%). Three SCCmec types were found. The most common type was SCCmecIV (49.23%, 32/65), followed by SCCmecⅡ (32.30%, 21/65) and SCCmecV (8.46%, 12/65). Conclusion The PVL gene-positive rate of CA-MRSA isolates in our hospitals is at a relatively high level. SCCmec type IV and SCCmec type V could spread among hospitals and cause a small scale epidemic. Their phenotypes have a variety of ST types.

Methods The specimen sources and the clinical distribution of the 381 pathogens isolated from 2007 to 2011 were retrospectively analyzed. The drug resistance was observed in ICU that causing nosocomial infections. Results The sputum was the major specimens source in ICU, accounting for 78.2%. Of the 381 pathogens causing nosocomial infections in ICU, the 262 gram-negative bacilli (68.8%), 70 gram-positive cocci (24.9%),and 49 fungi (17.4) were isolated, Among gram-negative bacilli the top three were acinetobacter baumannii (24.7%), klebsiella pneumonia(10.8%),and pseudomonas aeruginosa (9.2%). The drug resisitance rate of baumannii to antibiotics were more than 40%,beside carbapenem and B-Lactamaseinhibitors. The main gram-positive cocci of causing nosocomial infections was saphylococcus aureus in ICU. The drug resisitance rate of S. aureus to penicillin, erythromycin and gentamicin were higher than 50.0%. Conclusion The main distribution area of nosocomial infections was the respiratory tract and the gram-negative bacilli were the common pathogens in ICU. It was benefit to avoid presenting of drug resistant strain, and antibiotics should be reasonably used in clinic.
