Objective To explore the correlation between human cytomegalovirus(HCMV) infection with infantile hepatitis syn‐drome(IHS) and hepatic function damage .Methods The real‐time fluorescent quantitative polymerase chain reaction(PCR) was a‐dopted to test the urine HCMV DNA in 236 infants with IHS and 236 healthy infants ,respectively .The hepatic functions in 254 in‐fants with HCMV infection were analyzed retrospectively .Results Among these 236 cases of IHS ,the positive rates of HCMV DNA in urine sample was 62 .7% (148/236) .The positive rates of HCMV DNA and HCMV IgM in the IHS group were significant‐ly higher than those in the control group with statistical difference(P< 0 .01) .The liver function indexes in 254 infants with HCMV infection showed that the serum concentrations of total bilirubin (TBIL ) ,gamma glutamyl transpeptidase (GGT ) ,total bile acid (TBA) ,aspartate aminotransferase(AST ) and alanine aminotransferase(ALT ) were higher than the normal reference ranges ,and the differences were statistically significant(P < 0 .01) .Conclusion The detection rate of HCMV infection is high among the in‐fants with IHS in Guangxi area and HCMV is an important pathogen of IHS .HCMV may lead to hepatic function damage .

Objective To evaluate the role of nutritional parameters in prognosis,especially in the early and late mortality of hospital-acquired acute kidney injury (AKI) patients.Methods This study was a prospective cohort study conducted in a hospital comprising 1500 beds in Shanghai, China. One hundred ninety-four patients with hospital-acquired AKI, as determined using the RIFLE staging criteria,were enrolled as subjects after obtaining informed consent.Patients with AKI caused by postrenal obstruction,glomerulonephritis,interstitial nephritis or vasculitis were excluded.Nutritional evaluation,including subjective global assessment (SGA),anthropometric and laboratory examination,was conducted. Other laboratory measurements and clinical data were recorded.The primary outcome was early mortality (≤ 7 days) and late mortality (8-28 days) after enrolling into the study. Results AKI patients at enrollment were characterized by a high prevalence of malnutrition as determined by SGA, anthropometric and laboratory examination.Univariate analysis showed that the SGA,the serum levels of prealbumin,cholesterol and total lymphatic cells, and the Maastricht index were significantly different among early mortality,late mortality and survival groups.The serum prealbumin and cholesterol levels in the early death group were significantly lower than those in the survival and late death groups (P＜0.05).Multivariate analysis revealed that SGA,albumin,prealbumin and cholesterol remained independently and significantly associated with early mortality after adjusting for age,sex,dialysis,ventilation,hemoglobin,platelets,bilirubin,and Glasgow coma score.The areas under the receiver operating characteristic curve to predict early mortality for albumin,prealbumin and cholesterol were 0.591,0.736 and 0.603,respectively,with that of prealbumin significantly higher than others (P＜0.05). Conclusion Low levels of serum prealbumin,albumin and cholesterol at enrollment are independtly associated with increased early mortality in hospital-acquired AKI patients.
