OBJECTIVE:To find out potential financial risk in the listed Chinese pharmaceutical companies and to provide rec-ommendations. METHODS:The Z-score established with Altman E was adopted to classiy and analyzed empirically 143 listed phar-maceutical companies in China during 1998-2013 by sub-sectors(medical devices,pharmaceutical commercial,biological products chemical raw medicine,traditional TCM). The effects of some data in annual reports on Z-score were validated by using stepwise regression. RESULTS:The result showed that the average Z-score values percentage of the best 3 companies were 90.95%,47.96%and 41.25%,respectively,from 1998-2013;while for the worst 3 companies,the values were 0.80%,1.14%and 1.21%,respective-ly. At the same time,the financial situations of chemical raw medicine companies were the worst among 5 sub-sectors,of which dur-ing 2004-2006,the constituent ratios of companies in“Distress”zones went over 50.00%,which were 60.00%,55.20% and 53.60%,respectively. If counted by calendar year,the market value per share of 10 years and float of 9 years significantly affected the Z-score values(P<0.05);if counted by listed year,the market value per share of 15 years significantly affected the Z-score val-ues. CONCLUSIONS:Although major pharmaceutical companies have good financial status,financial crisis still exists in some companies. Especially,the financial situations of chemical raw medicine companies should not be neglected. The government should pay more attention to share price in order to prevent financial crisis which was induced by stock bubbles;at the same time,supervi-sion system should be established to evaluate the financial situation of listed pharmaceutical companies,even for all listed companies.

Objective To investigate the distribution of T follicular helper(Tfh)cell subsets in hepa-titis B patients at different immune stages and to clarify the relationships between the level of CXCL13 and the distribution of Tfh cell subsets. Methods Flow cytometry analysis was performed to detect the distribution of Tfh cells. Enzyme-linked immunosorbent assay(ELISA)was performed to measure the levels of CXCL13 in ser-um samples collected from hepatitis B patients. RT-PCR and Western blot assay were used to analyze the expres-sion of CXCL13 in HepG2 and HepG2. 2. 1. 5 cells. Results The percentages of Tfh1 cells were significantly up-regulated at the immune activation(IA)stage,while those of Tfh2 cells were significantly raised at the im-mune tolerance(IT)stage. The percentages of Tfh17 cells in patients at the stage of IT were similar to those in patients at the stage of IA,but were higher than those in responders with HBsAg seroconversion(RP)or healthy controls(HC). The expression of CXCL13 was positively correlated with the percentage of Tfh2 cells. More over,hepatitis B virus(HBV)enhanced the expression of CXCL13 at both transcriptional and translational lev-els. Conclusion HBV might up-regulate the percentage of Tfh2 cells through promoting the expression of CXCL13,which resulted in the induction of immune tolerance. Elucidating the functions of Tfh1,Tfh2 and Tfh17 cells and understanding the type conversion mechanism among the three subsets are important for further researches on HBV-induced immunosuppression.
