Objective To evaluate the diagnostic value of procalcitonin in early ventilator-associated pneumonia. Methods CNKI database, Wanfang database and PubMed (2000-2014) were applied for document retrieval through keyword searching approach. Meta-analysis was used in all eligible studies. Results Thirteen studies were collected. The sample bank includes 1 137 cases , of which 599 cases were diagnosed as ventilator-associated pneumonia. Heterogeneity test showed that the homogeneity of the studies was good. The value of the weighted sensitivity was 59% (43% ~ 73%), the specificity was 89% (82% ~ 93%), the positive likelihood ratio was 3.69 (3.21 ~ 4.23), the negative likelihood ratio was 0.42 (0.32 ~ 0.55), and the SROC area under the curve (AUC) was 0.86. The value of the weighted sensitivity was 81%(73% ~ 87%), the specificity was 83%(73% ~ 90%). Conclusion Procalcitonin can be regarded as a valuable marker in early ventilator-associated pneumonia diagnosis , when the cut-off point of PCT is 2.0 μg/L.

Objective To investigate Monilia infection and adverse pregnancy outcomes of pregnant women in labor.Methods Before informed consent,542 cases of pregnant women in labor were collected in Obstetrics Department of Maternity and Child Healthcare of Maoming City from January 2013 to April 2014,and all of these cases were examined by Monilia inspec-tion of vaginal secretions.All of these cases were 20 to 30 years old,without vaginal pathogenic infection symptoms,but in-cluded in a few of formulation of clinical features of vaginal Candida infection.With the two methods of 10% potassium hy-droxide solution wet sheet and Gram staining,if blastospore or pseudohypha of Candida mycoderma were found out in the two methods under microscope,this case was diagnosed as positive result,otherwise as negative result.Respectively choosing positive cases as observation group,and negative cases as control group,the indexes of premature rupture of membranes,per-ineum wound infection,neonatal thrush and neonatal diaper rash of the two groups were recorded.The statistical method:e-numeration data by chi-square test,measurement data using analysis of varianc.Results The positive rate of Monilia was 23.1% (125/542),higher than 19.3% reported in domestic.The incidence rates of neonatal diaper rash,premature rupture of membranes,neonatal thrush and perineum wound infection of the observation group were respectively 19.2%,8.0%, 16.8% and 12.8%,all much higher than the control group respectively was 8.4%,1.2%,3.8% and 1.7%,(χ2 =12.578~29.273,all P <0.01).Conclusion Monilia infection of pregnant women in labor could increase the chance of adverse preg-nancy outcomes.Healthy or clinical doctors should suggest that pregnant women early carry out routine examination and ear-ly treatment,in order to prevent adverse pregnancy outcomes.
