肺部解脲脲原体感染对支气管肺发育不良影响的Meta分析

目的 分析肺部解脲脲原体(UU)感染对支气管肺发育不良(BPD)的影响,为早产儿BPD的防治提供依据。 方法 检索Pubmed、Embase、Web of Science、Cochrane Library、中国知网、万方、维普及中国生物医学数据库(CBM)8个数据库,收集关于肺部UU感染对BPD影响的队列研究,检验标本为气管内分泌物,检索时间为自建库至2020年4月15日,采用Stata 15.1软件对纳入研究进行Meta分析。 结果 共纳入21项研究,均为队列研究,其中18篇文献以生后28 d为评估结局,9篇文献以校正胎龄36周为评估结局,共包含研究对象3 039例,其中UU感染组831例,非UU感染组2 085例。随机效应模型显示,UU感染不会增加BPD的发病风险(出生后28 d评估:RR=1.69, 95%CI:1.42~2.01, 矫正胎龄36周评估:RR=1.20, 95%CI:0.91~1.58)。 结论 基于现有研究数据,不能确定UU感染是BPD的影响因素,尚需统一的BPD诊断标准以及更高质量的队列研究来探索UU感染与BPD之间的关系。

The role of Ureaplasma parvum serovar-3 or serovar-14 infection in female patients with chronic micturition urethral pain and recurrent microscopic hematuria

BackgroundUreaplasma parvum (UP) is commonly isolated in the genitor-urinary tract and may cause various clinical features, including microscopic hematuria (MH). Some UP serovars are more commonly related with specific urogenital disease, but the evidences have been conflicting. This study primarily aimed to research the possible associations between specific UP serotypes and genito-urinary pathogenicity in female patients showing MH with/without chronic micturition urethral pain (CMP).MethodsThis study retrospectively reviewed 276 female patients having MH with/without CMP, who visited health screening center or female infertility clinic. All patients underwent multiplex polymerase chain reaction (PCR) tests with vaginal and urine samples to evaluate the infection rate and serotypes of UP. The antimicrobial susceptibility of UP and the predictors of CMP among UP infected patients were also analyzed. All patients were followed up at least for 6-months.ResultsForty-nine patients (17.8%) showed urinary UP infection. Urinary UP serotyping showed the prevalence of seorvar-1, -3, -6 and -14 were 24.5%, 30.6%, 18.4% and 26.5%, respectively. 79.6% of the urinary UP positive patients accompanied vaginal UP infection. 22 patients of the cohort (8.0%) had CMP whereas serovars-3 and -14 accompanied CMP in 54.5% and 41.0% cases, respectively. No serovars-6 infection case had CMP. 26.4% of the cohort were infertile whereas 10.9% of these infertile patients were positive for urinary tract infection with UP serotype-3 or -14. Doxycycline, josamycin and pristinamycin were the most active antibiotics with the lowest rate of resistance (0.0%) for treating UP. At 1-month post-initial treatment with doxycycline, all UP serotypes were eradicated and no patient complained of urethral discomfort. However, simultaneous urinary and vaginal reinfection of serovar-3 (5 cases) and serovar-5 (1 case) were confirmed at 3-months post-initial doxycycline therapy. The logistic regression analyses revealed that serovars-3 [hazard ratio (HR) 1.354, P value 0.018] and -14 (HR 1.103, P value 0.046) were significantly associated with CMP in female patients having MH.ConclusionsUP serovars-3 and -14 infections could be associated with CMP in female patients having MH. Doxycycline, josamycin and pristinamycin were effective for treating UP. Serovar-3 showed higher reinfection rate than other serotypes after antibiotics treatment.     

不育患者Y染色体AZF微缺失的分析

目的探讨Y染色体上AZF区域微缺失与男性不育的关系。方法采用多重PCR技术,对20例不育患者AZF4个区的l5个序列标签位点（STS）进行了微缺失检测和细胞遗传学检查。结果20例患者中共有3例发现微缺失（15%）。结论AZF微缺失是导致男性不育的重要原因之一,细胞遗传学检查与AZF微缺失无相关性。

Ureaplasma urealyticum infection in newborns: Three case reports

We report three newborns with different manifestations ofUreaplasma urealyticum infection; a term newborn with acute neonatal pneumonia and two very low birth weight infants with bronchopulmonary dysplasia and osteomyelitis of the femur, respectively. The association ofU. urealyticum with acute and chronic respiratory disease in term and preterm newborns has recently been reported. Our two cases are similar to other case reports from the literature, but we were unable to find any previous reports of osteomyelitis due toU. urealyticum in the premature babies. Isolation ofU. urealyticum in pure culture from the blood was considered to be related to local infection in all three patients. All patients were cured by erythromycin.
