目的 通过对婴幼儿泌尿系感染并发脓毒症的临床特点、病原菌情况及相关因素的分析,探讨其早期诊断和及时治疗的措施。方法 选取83例我科收治的确诊泌尿系感染合并脓毒症的婴幼儿作为研究对象,回顾性分析其临床表现、实验室检查及治疗预后情况。结果 所选婴幼儿均确诊泌尿系感染合并脓毒症,以男性患儿多见,全身中毒症状重,6月以下多以严重脓毒症、脓毒性休克为首诊表现,尿路刺激症状不明显。有明显细菌感染生物标记物的改变。细菌学培养共检出细菌22株,大肠埃希菌占54.55% (12/22),对头孢吡肟较为敏感,对亚胺培南、美罗培南全部敏感;屎肠球菌占22.73%(5/22),对万古霉素、利奈唑胺、替考拉宁敏感。结论 在婴幼儿常见的感染部位中,泌尿系感染容易被忽略。而小于6月的患儿更易并发严重脓毒症、脓毒症休克等危重症。因此,以脓毒症为首诊表现的婴幼儿应特别警惕泌尿系感染,尽可能早期明确感染部位,防止漏诊。首诊1小时内给予广谱抗生素治疗,可降低婴幼儿脓毒症的病死率,改善患儿预后。

Objective By analyzing the clinical features, laboratory tests, pathogenic bacteria culture and the treatments of infants and toddlers with urinary tract infection UTI accompanied with sepsis, we aim to guide the further clinical treatments and prevention. Methods We selected 83 cases from January 1, 2014 to December 31, 2016 in our hospital as the research objects which were accepted the diagnosis and treatments of urinary tract infection complicated with sepsis. Its clinical manifestations, laboratory tests, bacteriology examination and treatment prognosis were retrospectively analyzed. Results Among the selected infants and toddlers diagnosed with urinary tract infection complicated with sepsis, male patients were more common. Symptoms of systemic poisoning were observed in the majority especially in the children aging under 6 months, with severe sepsis and septic shock as the first manifestation, while conventional symptoms were not obvious. Biological markers of bacterial infection were significantly changed. In bacterial culture, 22 strains of bacteria were detected, Escherichia coli accounted for 54.55% (12/22), were almost sensitive to cefepime, and all sensitive to imipenem and meropenem; Enterococcus following accounted for 22.73% (5/22), could be more sensitive to vancomycin, linezolid, teicoplanin. Conclusion Urinary tract infection is common in under 3 years old babies. Patients aging under 6 months are more likely to be complicated with severe sepsis and septic shock. Therefore, we should be especially vigilant of the UTI among the babies whose first manifestations appear to be sepsis only. It is important to find out the site of infection as early as possible, in order to prevent misdiagnosis. It is also critical to use broad-spectrum antimicrobial therapy within 1 hour when severe sepsis is diagnosed in order to reduce the mortality of sepsis in infants and improve the prognosis.

Objective To analyze the correlation between viral load of chronic hepatitis B virus infection and liver function and pregnancy complications. Methods We selected 86 cases of pregnant women with chronic hepatitis B virus(HBV)in our hospital from January 2015 to December 2015 as the research objects, and then during the hospitalization to test the quality of the HBV deoxyribonucleic acid (HBV-DNA)for them before delivery. According to the HBV-DNA quantitative results, all patients were divided into low dosage group and high dosage group, and then the clinical data, liver function, the incidence rate of pregnancy complications and the outcomes of the two groups were compared; at last we analyzed the correlation among the HBV-DNA load, liver function of pregnant women during pregnancy and pregnancy complications. Results There was no difference between the two groups of pregnant women in the age, BMI, pregnancy and birth time, P>0.05; the low dose group was better than the high dose group in the liver function index during the pregnancy, P<0.01. The incidence of abnormal amniotic fluid volume (more or less) in the low dose group was higher than that in the high dose group, P<0.05; there was no significant difference between the two groups in the incidence of other complications, P>0.05. There was no statistical difference between the two groups in maternal and neonatal outcomes, P>0.05. The HBV load was positively correlated with the two liver function indexes ALT, 0<r<1, indicating that the higher the HBV-DNA, the higher theALT, the worse the liver function of the pregnant women. There was no correlation between HBV load and complications, |r|<0.3, P>0.05. Conclusion Chronic hepatitis B virus carriers during pregnancy with increasing viral load, liver function of pregnant women declined to maintain in normal level, but not associated with pregnancy complications; that of HBV-DNA positive pregnant women given close monitoring of disease through clinical routine treatment can ensure the safety of mother and child.

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.
