Résumé
<p><b>OBJECTIVE</b>To study the effects of Lingmao Recipe (LR) on starvation-induced autophagy in HepG 2.2.15 cell.</p><p><b>METHODS</b>Fifteen SD rats were selected to prepare LR drug serum. The Earle's balanced salt solution (EBSS) group, the EBSS + vehicle serum group, the EBSS + 5 times LR serum group, the EBSS + 10 times LR serum group, and the DMEM group were set up, 3 samples in each group. The HepG2.2.15 cells were cultured for 1, 2, 4, and 6 h respectively. The pEGFP-N1-LC3B eukaryotic expression vector was constructed and transfected with HepG2. 2.15 cell. The GFP-LC3B morphological changes were observed under fluorescent microscope. The ratio of the dotty GFP-LC3B number and the GFP-LC3B transfected HepG2.2.15 number was calculated. The intracytoplasmic autophagosome changes were observed using electronic transmission electron. The microtubule-associated protein 1 light chain 3 beta II/I was detected in HepG2.2.15 of each group using Western blot.</p><p><b>RESULTS</b>Two h after culture, when compared with the EBSS + vehicle serum group, GFP-LC3B changing from diffused distribution to dotted distribution was obviously inhibited in the EBSS +5 times LR serum group and the EBSS +10 times LR serum group (P<0.01). The electronic transmission electron showed that the formation of autophagosome was inhibited in the EBSS +5 times LR serum group and the EBSS +10 times LR serum group. Results of Western blot showed that microtubule-associated protein 1 light chain 3 beta II/I obviously decreased more in the EBSS +10 times LR serum group than in the EBSS +vehicle serum group (P<0.01).</p><p><b>CONCLUSION</b>LR could inhibit starvation-induced autophagy in HepG 2.2.15.</p>

<p><b>UNLABELLED</b>To analyse the live pathology characteristics in mild ALT-elevated (1 x ULN less than ALT less than 2 x ULN ) HBeAg-positive and HBeAg-negative chronic hepatitis B (CHB) patients, and to explore the influence of the age and HBV DNA level to liver pathology in different HBeAg status patients.</p><p><b>METHODS</b>All the patients who met the inclusion criteria form "eleventh five-year plan" National Science and Technology Major Project, the treatment program of integrative traditional and western medicine for CHB were enrolled in this study between October 2009 and March 2011 .B type ultrasound-guided liver biopsy was carried out in all patients and hepatitis B surface antigen (HBsAg) , HBeAg titer as well as HBV DNA level were detected at the same time. Hepatic tissue inflammation and fibrosis degree of patients according to HBeAg-positive and negative, age ( more than or equal to 40 years and less than 40 years), HBV DNA level (more than or equal to 10
