ABSTRACT
Objective To assess the expression of T cell subset in patients with hepatitis B virus-associated primary liver cancer (HBV-PLC) and its influence on the clinical outcome.Methods 136 cases with PLC were selected, and divided into HBV-PLC group (78 cases) and non-HBV-PLC group (58 cases) according to HBV infection.The percentage of CD4+T cells, CD8+T cells and Treg cells in serum was tested by flow cytometry.After 6 months of follow-up, HBV-PLC patients were divided into death group and survival group.Binary logistic regression analysis was performed to explore the factor and degree affecting clinical outcome of HBVPLC patients.Results As compared with non-HBV-PLC group, dysregualted T cell subset was observed in the HBV-PLC group, percentage of CD4+T cells and Treg cells in HBV-PLC patients was higher (P＜0.05), while CD8+T cell percentage was decreased (P＜0.05).The percentage of CD4+T cells and Treg cells was higher in death group than survival group (P＜0.05), but CD8+T cell percentage was lower than that of survival group (P＜0.05).T-lymphocyte subset (CD4+T cells and Treg cells) was a strong risk factor for adverse clinical outcome of HBV-PLC (OR values were 3.765 and 2.238, respectively, P＜0.05), but CD8+T cell was a protective factor (OR value was-3.537, P＜0.05).Conclusion Obvious dysfunction of T cellular immune function exists in HBV-PLC patients, and T cell subset may be a predictive factor for clinical outcome of HBV-PLC patients.
ABSTRACT
Objective To assess the quality of randomized controlled trials (RCTs) of delirium prevention of elderly published in China.Methods The literatures from China National Knowledge Infrastructure(CNKI),WANFANG Data and VIP Database for Chinese Technical Periodicals were evaluated according to Cochrane collaboration's tool for assessing risk of bias and Jadad scale.Results A total of 53 RCTs were included,14 (26.4％,14/53) described radom number table used to generate the random allocation sequence,4 (7.5％,4/53) conducted experiments in a blinded manner,7 (13.2％,7/53) did not use intentionto-treat to analyse those who did not complete the study,9 (17.0％,9/53) had high risk of other bias,none described allocation concealment mechanism and blinding to participants and intercention implementers.Based on Jadad scales,the score was 1-4,average score was (2.3±0.8),19 (35.8％,19/53) were high-quality literatures.Conclusions The quality of present published literatures is not high,the further domestic studies should be designed high-quality to better improve clinical practice.
