RESUMO

BACKGROUND: Chronic severe hepatitis B patients often have limited survival. This investigation aimed to evaluate the short-term effects of nucleoside analog therapy on chronic severe hepatitis B. METHODS: We retrospectively, randomly collected the data of 129 chronic severe hepatitis B patients: 55 were treated with entecavir, and the remaining 74 were not treated with nucleoside analogues. RESULTS: No significant difference in short-term survival rate was found between the group treated with entecavir and that treated without nucleoside analogues. Although entecavir greatly reduced HBV replication in different periods of therapy (P<0.001), the model for end-stage liver disease (MELD) score and liver function (alanine aminotransferase, albumin, bilirubin, prothrombin time) showed no significant change. No significant differences were found in MELD scores and liver function in patients with different HBV DNA levels (< or =10(4) copies/ml, >10(4) to <10(6) copies/ml, > or =10(6) copies/ml). Nor correlation was observed between HBV DNA levels and MELD scores in different periods of therapy (P>0.05). The HBV DNA levels of patients who survived for over 3 months or less than 3 months were not significantly different either. However, the MELD score and parameters of liver function (albumin, bilirubin, prothrombin time) were different between the two groups (P<0.05). CONCLUSION: These results suggest that short-term suppression of HBV replication may not slow down the progression of liver failure in patients with chronic severe hepatitis B.

RESUMO

The study of sarcosaphagous insects is a subspecialty in forensic medicine based on the knowledge of entomology. It could help to determine the time of death, especially the postmortem interval in decomposed cases. This paper explores its history, species and erosion process of sarcosaphagous insects. It reviews the species identifying methods with molecular biology and entomological morphology. Details of its application in estimating postmortem interval in recent years and study of sarcosaphagous insects in the field of forensic medicine are summarized.
