Objective To investigate the relationship between hepatitis B virus reactivation and the level of blood T-lymphocyte subsets.Methods T lymphocyte subsets ( CD3,CD4,CDs ),CD4/CDs level of 40 patients with chronic carriers of hepatitis B virus and 35 patients with hepatitis B virus re-activation were detected by Flow cytometry(Epics XL).Results The hepatitis B virus reactivation in patients with CD3,CD4 and CD4/CDs levels were significantly lower than the chronic hepatitis B virus carriers,The difference between the two groups patients was significant[(71.31 ±5.20)％ vs (68.57 ±6.10)％,(37.82 ±4.90)％ vs (32.12 ±5.93)％,(1.37 ±0.28) vs (1.18 ±0.43 ),all P ＜ 0.05].Conclusion The levels of CD3,CD4 and CD4/CD8 ratio were significantly declined,it may be the one important reason of hepatitis B virus reactivation.

Objective To investigate the clinical effects of fenofibrate and polyene phosphatidylcholine in treatment of non-alcoholic fatty liver disease.Methods 86 patients with non-alcoholic fatty liver disease were randomly divided into two groups.45 cases in therapy group received 0.2g of fenofibrate once a day,and the others in control group received 456mg of polyene phosphatidylcholine for three times per day.All of the patients were treated for 12 weeks.Liver function,blood fat,clinical effect and liver B ultrasonic were analyzed before treatment and after 12 weeks.Results The improvement of liver function,blood fat,and liver ultrasonic imaging in therapy group was better than that in the control group.The cure rate was 82.2％ in therapy group and 63.4％ in control group.There was a statistical significance between the two groups ( x2 =3.874,P ＜ 0.05).Conclusion Fenofibrate had significant therapeutic effect in treatment of non-alcoholic fatty liver disease with lower costs and lower side effects.

Objective To explore the changes ofT lymphocyte subsets CD3+,CD4+,CD8+ in hepatitis B reactivation after chemotherapy.Methods Flow cytometry was used to detect T lymphocyte subsets of 32 patients with hepatitis B reactivation before and after chemotherapy.In addition,25 patients without hepatitis B reactivition were chosen as control group.Results After chemotherapy,the percentage of CD3+ and CD4+ T lymphocytes and the ratio of CD4+/CDs+ were significantly reduced than those before chemotherapy (P ＜ 0.05).However,the percentage of CD8+ T lymphocytes was not significantly changed(P ＞ 0.05).Conclusion The chemotherapy can change the number and ratio of T lymphocyte subsets,the inhibition of the cellular immune function is one of the reason of hepatitis B virus reactivation.
