不同女性人群支原体感染状况分析

目的调查和分析解脲脲原体（Uu）、人型支原体（Mh）在生殖道感染者和健康女性人群中的感染状况，探讨其致病性和致病条件。方法在同期采集生殖道感染者和健康女性生殖道分泌物。采用培养法和倍比稀释法进行Uu和Mh的定性培养和颜色变化单位（CCU）浓度检测。对2类人群的支原体感染状况进行分析。结果生殖道感染者支原体阳性率（84．1％），显著高于健康女性人群（55．8％）（χ^2=26．4571，P〈0．0001）；生殖道感染者以Uu和Mh的混合感染为主，健康女性以单纯Uu感染为主。2者比较差异有统计学意义（χ^2=57．2132，P〈0．0001）。支原体CCU浓度检测结果显示，妇科炎症人群支原体浓度显著高于健康女性人群（Uu：秩和检验Z=-4．3094．P〈0．0001；Mh：秩和检验Z=-2．8820。P=0．0040）。结论Mh的致病性强于Uu；Uu和Mh并存具有一定的协同致病作用。且在感染菌量较高时易致临床症状出现。因此。对女性生殖道感染者进行支原体定量或半定量检测和有针对性治疗具有重要意义。     

解脲脲原体感染治疗效果影响因素调查研究

目的调查分析导致患者解脲脲原体(Uu)感染未能根治和治疗无效的相关因素,以提高临床Uu感染的治愈率。方法对Uu感染治疗无效或有残余支原体量的患者,分析其性别、给药途径、疗程、3类常用抗菌药物(大环内酯类、四环素类、喹诺酮类)选择、体外药物敏感试验等相关因素,并比较单一和联合用药治疗方案与Uu残余量的关系。结果克拉霉素、多西环素、米诺环素体外药敏试验敏感率依次为92.35%、87.76%、86.74%;而氧氟沙星、左氧氟沙星、罗红霉素敏感率仅为12.25%、35.71%、37.76%。性别、给药途径、疗程均影响Uu感染疗效(P<0.01):Uu未能根除患者中,女性患者占83.87%;静脉用药者占62.90%;疗程≤7d者占74.19%。克拉霉素治疗Uu感染所致Uu残留存在男女性别差异(P<0.01);联合用药组Uu转阴率为98.75%,高于单一药物治疗组(P<0.01)。结论选择敏感性药物,除考虑性别差异外,足疗程及联合用药有助于提高对患者泌尿生殖系残余Uu的清除。

Certain type of chronic lung disease of newborns is associated with Ureaplasma urealyticum infection in utero

BACKGROUND: Recent studies of chronic lung disease (CLD) of newborns emphasize the contribution of antenatal infection. However, the association of Ureaplasma urealyticum infection and CLD has been controversial. The purpose of the present paper was to determine whether U. urealyticum is associated with chorioamnionitis (CAM) and a certain type of CLD. METHODS: One hundred and five infants <32 weeks of gestation who were admitted to the neonatal intensive care unit at Jichi Medical School Hospital, who underwent both histological and microbiological examinations and who survived to discharge were included. CAM was determined by histological examination. Placenta, gastric and tracheal aspirates, and nasopharyngeal swabs were cultured for Mycoplasma and other microorganisms. CLD was defined as oxygen needed at 28 days of age with symptoms of persistent respiratory distress and hazy or emphysematous and fibrous appearance upon X-ray. CLD was further divided into two subtypes according to the presence of antenatal infection. RESULTS: CAM was associated with premature rupture of membrane (odds ratio [OR], 10.19; 95% confidence interval [CI]: 3.10-33.56), placental colonization of U. urealyticum (OR 6.73, 95%CI: 1.89-23.91), neonatal colonization of other microorganisms (OR 7.33, 95%CI: 1.22-44.13) and level of IgM (OR 1.06, 95%CI: 1.01-1.11). Comparisons between CLD and non-CLD patients showed that gestational age (OR 0.43, 95%CI: 0.30-0.61) and white blood cell count (WBC) at birth (OR 1.06, 95%CI: 1.01-1.11) were risk factors for CLD, while gestational age (OR 0.38, 95%CI: 0.23-0.64), neonatal colonization of U. urealyticum (OR 5.98, 95%CI: 1.17-30.6) and WBC (OR 1.08, 95%CI: 1.01-1.15) were independent risk factors for infection-related CLD compared with non-CLD. Within CLD, infection-related CLD was associated with neonatal colonization of U. urealyticum (OR 43.7, 95%CI: 2.84-673.8) and WBC (OR 1.27, 95%CI: 1.07-1.50). CONCLUSIONS: Placental colonization of U. urealyticum was significantly related to CAM; and neonatal colonization of U. urealyticum and leukocytosis at birth were risk factors for infection-related CLD.     

解脲脲原体感染与精子DNA完整性的相关性的研究

目的:探讨不育男性解脲脲原体(Uu)感染与精子核DNA完整性及精液各参数的相关性。方法:95例不育症患者的精液用Uu培养液进行解脲脲原体的培养,按WHO的标准,用计算机辅助精液分析系统(CASA)进行精液各参数的分析,然后通过精子低渗肿胀实验,吖啶橙(AO)荧光染色检测精子膜的完整性和精子核DNA的完整性。结果:Uu阳性40例,Uu阴性55例,Uu阳性组与阴性组比较,精子核DNA完整性与精子的密度、a+b级精子百分率以及精子的肿胀率都有显著性差异(P<0.01,P<0.05)。同时Uu阳性组与阴性组的精子核DNA完整性与精子的肿胀率存在显著的正相关性(r=0.438,P=0.014;r=0.438,P=0.01)。结论:Uu感染能够降低精子膜的完整性以及精子核DNA的完整性,这可能是Uu致男性不育的又一因素。

(S)-(-)-9-氟-2,3-二氢-3-甲基-10-[4-(2-吡啶)-1-基哌嗪]-7-氧代-7H-吡啶[1,2,3-de][1,4]苯并噁嗪-6-羧酸(YH-6)与其它抗微生物药体外抗支原体活性的比较(英文)

目的:测定新喹诺酮YH-6对支原体的抑制活性并与其它抗微生物药剂作比较。方法:MIC的测定采用微量稀释法。结果:YH-6对解脲支原体(Uu),人型支原体(Mh),口腔支原体(Mo),唾液支原体(Ms)的MIC分别为250μg·L~(-1),500μg·L~(-1),125μg·L~(-1),125μg·L~(-1),它的抑制活性与红霉素,柱晶白霉素相当,是氧氟沙星的2-8倍。Uu,Mh对YH-6及交沙霉素和泰洛星不易产生诱导耐药性,而对红霉素和四环素易产生诱导耐药性和多重耐药性,而对YH-6,交沙霉素和泰洛星无多重耐药性。结论:YH-6对支原体有很强的抑制活性,且不易形成诱导耐药性。Uu和Mh的红霉素或四环素抗性菌株对YH-6无多重耐药性。     

Analysis on Factors Related to Infection of Ureaplasma Urealyticum in Infertile Couples

Objective：To study the relationship between related factors and infection of Ureaplasma Urealyticum(UU).Design：A clinical abservational study.Methods:A total of 212 female and 338 male infertility patients were recruited.The statistic methods are chisqaure test and logistic regression analysis.Results:1) Age was related to the infection of UU:the older women‘s age,the higher the UU infection rate.As the women’s marrige age and husband age increased,the infection rate was reduced.2) Occupation is related to the infection of UU,the infection rate being highest in the peasants group.3)As husband smoked more cigarettes and drank more alcohol,the infection rate of UU was higher.4)The more sexual life,the higher the infection rate.5)The duration of infertility had nothing to do with the UU infection.Conclusion:The women‘s age,marriage age,husbands‘ age,occupution,sexual life frequency and husbands‘s smoking and alcoholism are factors related to UU infection.
