RESUMO
<p><b>OBJECTIVE</b>To characterize genotypic resistance within HBV RT region in chronic hepatitis B (CHB) patients with nucleos(t)ide analogue (NA) treatment.</p><p><b>METHODS</b>Serum samples of 229 CHB patients with NA treatment were obtained. Full-length HBV RT sequences were amplified, sequenced and analyzed, on the following NA resistant (NAr) mutations belonging to different NAr pathways.</p><p><b>RESULTS</b>Among 229 HBV isolates, 14.41% (33/229) and 85.59% (196/229) were genotype B and C, respectively; and the patients with HBV genotype C may be more susceptible to develope resistant mutations than patients with HBV genotype B(chi2 = 2.95, P < 0.05). NAr mutations were detected in 63 CHB patients. Mutations were not found at rtI169, rtT184, rtA194 or rtS202. RtM204 mutations were detected at the highest frequency among 63 mutants (40/63, 63.49%) and found to display 11 combination mutation patterns, in which rtM204I were associated with rtL80I/V and rtL180M, and rtM204V were associated with rtL1l80M, respectively. Conclusions There are complicated mutation patterns in the HBV RT region for chronic hepatitis B (CHB) patients with nucleos(t)ide analogue (NA) treatment. RtM204V/I mutation was the highest.</p>

<p><b>OBJECTIVE</b>To study the effect of medical ozone in the treatment of chronic hepatitis B.</p><p><b>METHODS</b>42 patients with chronic hepatitis B were divided randomly into two groups. 22 patients treated with basic therapy were as a control group. 20 patients treated with basic therapy plus ozone therapy were taken as a treatment group. Index of biochemistry and virology were studied at initial and post-treatment 8 weeks.</p><p><b>RESULTS</b>After the treatment, liver function of the treatment group and the control group had more significant improvement. The treatment group complete effective and partial effective were 10% and 35% difference. The control group complete effective and partial effective were 4.6% and 13.6% (P < 0.05).</p><p><b>CONCLUSION</b>Treatment of medical ozone on patients with chronic hepatitis B is effective.</p>
