RESUMO
Objective To investigate the epidemiologic features of infant rotavirus(RV) diarrhea in Guilin area .Methods The detection of group A rotavirus were performed on 1 300 patients from Guilin 181st hospital by using immune colloidal gold method , and the epidemiological analysis were done according to the detection results .Results In the 1 300 patients ,132 were found rotavir‐us positive ,the total positive rate was 10 .15% .The positive rate of >1-2 years old group was the highest(23 .08% ) ,compared with other age groups(P<0 .05) .In November ,December and January ,the positive rates were 24 .14% ,20 .00% ,23 .53% ,respec‐tively .Compared with the positive rate in other months ,there was statistically significant difference(P<0 .05) .Conclusion Infants of 6 months to less than 2 years old in Guilin have higher detection rate of RV infection ,and the infection peak appears in autumn and w inter .
RESUMO
Objective To explore the clinical accuracy of urine cellular components of RBC,WBC,etc.detected by the Urit-1500 urine analyzer.Methods 1 085 urine samples in this hospital from June to October 2013 were selected and detected by the Urit-1500 urine analyzer and the microscope detection respectively.The results of urine cellular components detected by the urine analy-zer were analyzed.Results In 1 085 urine samples,the coincidence rate of two detection methods in detecting RBC and WBC was 93.8%(1 018/1 085)and 94.0%(1 020/1 085)respectively.In 295 RBC positive urine samples tested by the urine analyzer,the number of negative results tested by microscopy was 49,accounting for 16.6%.In 790 RBC negative urine samples tested by the u-rine analyzer,the number of negative results tested by microscopy was 18,accounting for 2.3%.In 197 WBC positive urine samples tested by urine analyzer,the number of negative results tested by microscopy was 28,accounting for 14.2%.In 888 WBC negative urine samples by urine analyzer,the number of negative results tested by microscopy was 37,accounting for 4.2%.Conclusion De-tecting urine RBC and WBC by using the Urit-1500 urine analyzer should combined with the microscopy and other test indexes and even clinical data to conduct the comprehensive analysis for reducing the misdiagnosis and missed diagnosis as far as possible.
RESUMO
Objective To investigate the clinical value of detection of procalcitonin(PCT ) and high sensitivity C-reactive protein (hs-CRP) in early diagnosis of bloodstream infection(BSI) .Methods The serum levels of PCT and hs-CRP of 58 BSI patients(test group) and 58 non BSI patients(control group) were detected .The early diagnosis value of PCT and hs-CRP was evaluated by ROC curve .Results There were significant difference between the serum PCT and hs-CRP levels of test group and control group(P<0 .05) .The ROC AUC of PCT and hs-CRP were 0 .902(95% CI:0 .850-0 .955) and 0 .706(95% CI:0 .611-0 .801) ,respectively . With 2 .24 ng/mL being the diagnostic cut-off value ,the diagnostic sensitivity ,specificity ,positive predictive value ,and negative pre-dictive value of PCT were 77 .6% ,91 .4% ,90 .0% ,and 80 .3% ,respectively .With 64 .83 mg/L being the diagnostic cut-off value ,the di-agnostic sensitivity ,specificity ,positive predictive value ,and negative predictive value of hs-CRP were 74 .1% ,62 .1% ,54 .4% ,and 59 .5% , respectively .Conclusion Detection of serum PCT and hs-CRP has important clinical value in early diagnosis of BSI .
