Objective To investigate the diagnostic values of model of end-stage with incorporation of serum sodium (MELD-Na) score, chronic liver failure-sequential organ failure assessment (CLIF-SOFA) score and APASL-ACLF research consortium score (AARC-ACLF) for evaluation of prognosis of hepatitis B virus related acute-on-chronic liver failure (HBV-ACLF). Methods A total of 72 consecutive patients with HBV-ACLF were included in the study and divided into two groups (group A and group B) according to the prognosis in three-month. Group A were included 29 patients with stable disease or better after medical treatment at least for 3 months, and group B included 43 patients who were dead after treatment or received liver transplantation as failure of medical treatment. When the patients were diagnosed as ACLF or after admission, the data were collected. Results of the laboratory examination were collected when the international normalized ratio (INR) was minimum. Data of total bilirubin (TBIL), prothrombin time (PT), INR, serum creatinine (Cr), serum sodium (Na), albumin (ALB), MELD-Na, CLIF-SOFA and AARC-ACLF scores were calculated respectively. The comparative analysis was performed. Areas under the receiver operating characteristic curve (AUC-ROC) of MELD-Na and CLIF-SOFA scores were used to assess the short-term prognosis in patients with acute-on-chronic liver failure. Results The values of TBIL, INR, MELD-Na, AARC-ACLF and CLIF-SOFA were significantly higher in group B than those in group A (P<0.05). The serum level of Na was significantly lower in group B than that of group A (P<0.05). The area under curve (AUC) values generated by the ROC curves was higher for CLIF-SOFA score (AUC 0.887) than that of MELD-Na score (AUC 0.764) (Z=2.255, P<0.0167). The AUC values generated by the ROC curves showed no significant differences between CLIF-SOFA score and AARC-ACLF score (AUC 0.825) or MELD-Na score and AARC-ACLF score (Z=1.361, 1.127, P>0.0167). The cut-off scores of MELD-Na, CLIF-SOFA and AARC-ACLF were 23.84, 8.50 and 8.50 respectively. Conclusion MELD-Na, CLIF-SOFA and AARC-ACLF scores have appreciable values to evaluate the prognosis in patients with HBV-related ACLF. AARC-ACLF is better than that of MELD-Na and CLIF-SOFA in assessing prognosis of HBV-related ACLF.

Objective To explore the correlation between the enhancement pattern of hepatocellular carcinoma (HCC) on contrast-enhanced ultrasound (CEUS) and its tumor differentiation on histopathology. Methods HCC lesions (n=259) from 224 patients were retrospectively evaluated with CEUS and histopathological examination. CEUS was performed with SonoVue. The characteristics of blood perfusion and parameters of the time-intensity curve (TIC) were analyzed by ACQ soft?ware. Histopathological diagnoses were decided base on Edmonson grading system. Results Pathologic grading of HCC was not related to the arrival time(P>0.05);The washing-out time point and the enhancement time point and peak time point all appeared earlier in poorly differentiated HCC group, than those in moderately differentiated HCC group than those in well differentiated HCC group(P<0.01);The enhancement time point and the expurgation time point are shorter in poorly differ?entiated HCC group than those in moderately differentiated HCC group than those in well differentiated HCC group. All dif?ferences were with statistical significance. The mode of arterial perfusion in early stage was divided into 3 types:spider web type, radiative type and mixed type. The well differentiated HCC group mainly presented as radiative type ( 28/49, 47.14%). But the most of poorly differentiated HCC group mainly present as spider web type(88/127, 69.29%). The mix type was more common in moderately differentiated HCC group(49/83, 59.03%). Conclusion CEUS show different features of TIC pa?rameters and blood perfusion in different pathological stages of HCC lesions so it can serve as a method to assess the biologi?cal behavior of hepatocellular carcinoma.

Objective To assess prevalence and risk factors of illness within the past 2 weeks among rural residents in Menglian,under the background of essential public health service implemented generally. Methods In February 2012, the questionnaire method was employed to investigate the two-week morbidity in 2011 rural residents sampled by multistage stratified random sampling from Menglian population. Results The prevalence, that of illness within two-week among 2011 rural residents in Menglian, was 97.5‰ (95%CI 84.5‰-110.5‰) . It was lower than that of the rural region IV in China (149.6‰, <0.05) .Its age trend was the same as that of the rural region IV in China,the prevalence in 0-14 years old children,however,was higher than the counterpart in the rural region IV in China. The diseases, which two-week morbidity ranked the top five, were acute upper respiratory infection, acute gastroenteritis, hyperostosis, acute tracheobronchitis and rheumatoid arthritis. The results of multilevel logistic regression model fitted by group-level explanatory variable mountainous area, individual-level random slopes variable gender and other individual background variables indicated that there were across-level interactions between mountainous area and gender ( <0.05), the family income lower than RMB 15000 (odds ration 3.2378, 95%CI 1.9014-5.5130) and age (odds ration 1.0163, 95%CI 1.0002-1.0327) had a positive effect to two-week morbidity, and contrasting to unmarried, married had a negative effect to two-week morbidity (odds ratio 0.4727, 95%CI 0.2534-0.8819) . Conclusions Comparing with that of the rural region IV in China before implementing essential public health service, the two-week morbidity in Menglian was lower. For further elevating the health level of population, the strategies, such as intensifying material and child hygiene in the mountain area, improving sanitary conditions of low income family, and updating health consciousness in single population,would be implemented.
