Objective To determine the expression of CD38 and HLA -DR on CD +8 T cells in patients with chronic hepatitis B and HBV carriers,and to disscuss the relation between immune activation and disease progression of HBV infection.Methods Thirty -two chronic hepatitis B patients receiving adefovir dipivoxil treatment,31 HBV carriers and 28 normal controls were collected.The counts of CD +4 and CD +8 T cells and the percentage of CD +8 CD +38 and CD +8 HLA -DR +T cells were tested by flow cytometry.HBV DNA and liver function were tested in the central laboratory of our hospital.Results The percentage of CD +8 CD +38 T cells in CHB patients was (58.4 ±12.7)%,and was higher than that in HBV carriers (46.8 ±8.5)% and normal controls (46.8 ±8.5)%,and decreased after adefovir dipivoxil treatment (34.2 ±9.4%)(F =8.27,P =0.000).The percentage of CD +8 CD +38 T cells in HBV carriers was (43.3 ±12.5)%,and was much higher than that in normal controls (9.8 ±5.7)%(F =13.48,P =0.000).The percentage of CD +8 HLA -DR + T cells in CHB patients was higher than that in normal controls,but similar to that in HBV carriers (37.1 ±11.3)%.CD +8 HLA -DR + T cells in CHB patients also decreased after adefovir dipivoxil treatment (P <0.05 ).Conclusion Our study demonstrates that activation of CD +8 T cells is increased in HBV infection but decreased by adefovir dipivoxil treatment.The percentages of CD +8 CD +38 and CD8 +HLA -DR +T are good markers for disease progression of HBV infection.

OBJECTIVE:To observe the effect of compound glycyrrhizin on patients with chronic type B hepatitis.METH_ ODS:126patients with chronic type B hepatitis were randomly divided into two groups:the control group was administered with common therapy like reducing jaundice and protecting liver;the trial group was administered with compound glycyrrhizin plus the therapy of the control group.Time of therapy for both groups was8wk.RESULTS:The total effective rates for the tri_ al group and the control group were93.6%and33.3%,respectively,and significant differences were noted between groups(P

Objective To investigate the direct economic loss of nosocomial infection at a tertiary hospital, so as to provide data support for the improvement of hospital infection control. Methods Inpatients discharged in 2013-2015 period were divided into two groups at a 1:1 pairing ratio, having those suffering from nosocomial infection in only one occasion as the infection group, and those without as the non-infection group. The two groups were compared of their differences in days of stay and hospitalization expenses. Results The days of stay of the infection group were significantly longer than the non-infection group, averaging 6 days longer in terms of the median. Compared with the non-infection group, the total hospitalization cost and the differences with sub-categories other than the treatment cost were of significance. The costs over the non-infection group were mostly contributed by drugs, accounting for 50. 39%, while 23. 50% of which were spent on antibiotics. The additional antibiotics costs were mainly incurred by respiratory tract infections during hospitalization, as the costs of antimicrobial agents for the infection group were 27. 34 times that of the non-infection group. The second contributor was surgical site infection, with the cost of antibiotics 7. 63 times that of the non-infection group. Conclusions Hospital infections prolong the days of stay, increase direct economic loss, especially increase the cost of antibiotics. Prevention and control of respiratory system and surgical site infection can effectively reduce the direct economic loss of hospital infection.
