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 study the clinical features and gene mutation of congenital hyperinsulinism (CHI). Methods Clinical data of one newborn infant with CHI were retrospectively analyzed, and relevant literatures were reviewed. Results The infant was admitted at 24 days after birth due to recurrent hypoglycemia. Genetic examination revealed the single heterozygous mutation on ABCC8, which conifrmed the diagnosis of CHI. Experimental treatment of Diazoxide was effective. The blood glucose was normal in the follow up. Conclusions The improvement of genetic testing at the soonest can not only helps early diagnosis of CHI, but also guides the long-term clinical management of CHI.

OBJECTIVE:To observe therapeutic efficacy and safety of S-1 capsules combined with recombinant human end-ostatin in the treatment of middle and advanced primary liver carcinoma. METHODS:Totally 94 patients with middle and advanced primary liver carcinoma in the First College of Clinical Medical Science of China Three Gorges university during Feb. 2012-Dec. 2014 were divided into combination group(48 cases)and control group(46 cases)according to random number table. Both groups were given S-1 capsules 40-60 mg orally within 30 min after breakfast and supper. Combination group additionally received Recom-binant human endostatin injection 150 mg added into 0.9%Sodium chloride injection 210 mL with portable micro pump for continu-ous pump of 120 h. A course involved 14 d treatment and 7 d interval. Short-term objective therapeutic efficacy,clinical benefit re-sponse (CBR) and ADR were evaluated after 2 courses. Disease progression time and average survival period were compared be-tween 2 groups. RESULTS:Objective response rate,disease control rate,disease progression time and average survival period of combination group were 14.6%,66.7%,(5.5 ± 1.3) months,(10.7 ± 3.8) months;those of control group were 8.7%,45.6%, (4.8±1.2)months,(8.9±3.3)months,with statistical significance between 2 groups(P<0.05). CBR rate of combination group (79.2%)was significantly higher than control group(52.2%),with statistical significance(P<0.05). There was no statistical sig-nificance in the incidence of ADR between 2 groups (P>0.05). CONCLUSIONS:S-1 combined with recombinant human end-ostatin show good therapeutic efficacy and tolerance for patients with middle and advanced primary liver carcinoma,and do not in-crease the incidence of ADR.

Objective To study normal flora components of conjunctiva, explore the relationship between normal flora and ocu- lar bacterial infections.Methods The data of 1 198 bacterial cultures of conjunctiva in non-infectious cataract patients were re- viewed and compared with the results of 985 specimens of conjunctivitis, keratitis and endophthalmitis from January 2000 to December 2004.Results Positive culture of conjunctiva in non-infectious cataract patients was 628 in 1 198 specimens (52.4%).These bacteria including gram-positive cocci and gram-neganve bacilli constituted the normal flora of conjunctiva. Staphylococcus epidermidis was the predominant bacteria (51.1%, 341/667) and its prevalence increased during this 5-year period.S.epidermidis and S.aureus were also the most frequently isolated pathogens in specimens of conjunctivitis, keratitis and endophthalmitis.The correlation was statistically significant between the positive rate in normal eye and conjunctivitis or keratitis in terms of these two species, but not statistically significant between normal eye and endophthalmitis.The resistance rate of normal flora of conjunctiva to ampicillin, amikacin, tobramycin, ciprofloxacin, and ofloxacin increased year by year. The resistance rate to gentamicin and the combination of two drugs decreased.The changing resistant pattern was similar in pa- tients with eye infection.Conclusions There is a close relationship between the normal flora S.aureus and S.epidermidis of conjunctiva and the bacterial infection of ocular surface, but no significant correlation between normal flora and the pathogen of endophthalmitis.
