Objective To observe the level changes of interleukin-15 (IL-15) and its role and clinical sig-nificance in severe type B hepatitis(HB). Methods IL-15 levels of 47 cases of severe HB and 20 cases of healthy subjects were detected by ELISA,meanwhile the alanine aminotransferase (ALT),total bilirubin (TBIL) and pro-thrombase activity (PTA) were measured as well. The correlation between IL-15 and ALT,TBIL and PTA were ana-lyzed. Results IL-15 in severe HB eases were higher than in control group [(18.9±7.5 ) ng/L vs. (5.9±2.0) ng/L,P <0.01] ,which was higher in death group than in survival group[(24.1±7.5) ng/L vs. (15.7±5.4) ng/L, P<0.01]. IL-15 level was decreasing with the improvement of general condition and liver function recovery. In addition, IL-15 in severe HB was positively correlated with TBIL (r=0.570,P<0.01) and negatively correlated with PTA(r=-0.529,P<0.01) but was not significantly correlated with ALT(r=0.099,P>0.05). Conclusion IL-15 may take part in the pathogenesis of severe HB ,which is consistent with disease condition and is closely re-lated to the improvement of disease. The detection of IL-15 may exert a predicting role in the prognosis of severe HB.

Objective To investigate the correlation of hepatitis B virus (HBV) markers between umbilical cord blood and maternal serum.Methods A total of 340 HBsAg positive mothers who delivered at the Third People' s Hospital of Changzhou during August 2009 and November 2010 were included in the study.HBV markers in the maternal serum before childbirth and umbilical cord blood after birth were quantitatively detected.The neonates received 3 doses of hepatitis B vaccine and 2 doses of hepatitis B immunoglobulin (HBIG),and followed up for 12 months.Measurement data were expressed as median (M),and Kruskal-Wallis test and Spearman correlation analysis were performed.Results There were 175HBeAg-positive and 165 HBeAg-negative mothers,and a total of 341 infants were delivered.The positive rates of HBsAg,anti-HBs,HBeAg,anti-HBe and anti-HBc in maternal serum were 100.00%,0.0%,51.47%,38.82% and 99.41%,respectively; while those in umbilical cord bloods were 14.66%,0.59%,26.69%,39.88% and 95.31%,respectively.HBsAg concentration in maternal serum of HBsAg-positive umbilical cord blood group was higher than that of HBsAg-negative umbilical cord blood group (419.40∶ 387.95,x2 =4.592,P < 0.05) ; while HBsAg concentration in umbilical cord blood of HBeAg-positive maternal serum was higher than that of the HBeAg-negative maternal serum group (0.04 ∶ 0.01,x2 =5.674,P < 0.05).Anti-HBe and anti-HBc in umbilical cord blood were positively correlated with those in maternal serum (r =0.838,0.764,P < 0.01).Seven out of 62 (11.29%) infants were infected with HBV in HBeAg-positive maternal serum group; while no infant infected in HBeAg-negative matemal serum group.Conclusion The higher maternal serum HBsAg concentration,the greater the risk of perinatal transmission,and infants born by HBeAg-positive mothers are of high risk of HBV infection.

Objective:
To explore the relationship between liver controlled attenuation parameters (CAP) and body fat mass and its distribution.
Methods:
From May to December 2018, 978 adult patients visited at the fatty liver center of the Third People's Hospital of Changzhou were treated. The patient's liver controlled attenuation parameters were measured by transient elastography and the body fat mass and its distribution were measured by bioelectrical impedance technology. Pearson’s correlation coefficient was adopted to describe the correlation between liver CAP value and body mass index (BMI), body fat mass index (BFMI), trunk fat mass index (TFMI), limbs fat mass index (LFMI) and visceral fat area (VFA). Receiver operating characteristic curve (ROC) and area under the curve (AUC) were used to evaluate BMI, BFMI, TFMI, LFMI and VFA to differentiate the cut-off points and efficacy of CAP for diagnosing grading of fatty liver changes in S0-1 and S2-3.
Results:
In 653 cases of male, S0 ~ S3 accounted for 4.90%, 3.37%, 22.36% and 69.37%, respectively, and in 325 cases of females, S0 ~ S3 accounted for 7.38%, 6.46%, 13.23% and 72.92%, respectively. Female patients had more visceral, trunk and limbs fat than male (
