Objective To explore the clinical features and diagnosis of pulmonary sarcoidosis.Methods The data of 60 cases of pulmonary sarcoidosis confirmed by pathology was reviewed to determine the clinical features and the value in the diagnosis of sarcoidosis.Results The main clinical manifestations of sarcoidosis included bilateral hilar and mediastinal lymphadenopathy.The results of lung function tests showed that these patients had restrictive ventilating obstacles with decreased DLCO.The diagnosis was confirmed in 80% of the bronchial mucosa biopsies and 77.8% of the transbranchial lung biopsies through fiberotic bronchoscopy,87% of the biopsies of peripheral lymphnodes and 87.5% of the subskin nodes biopsies.Conclusion Nonspecific constitutional symptoms may occur in the cases of sarcoidosis.To the diagnosis of intrathoracic sarcoidosis,peripheral lymph nodes biopsies,the bronchical mucosa biopsies and TBLB are the convenient methods with highly definite diagnosis rate and microinvasion in clinical practice.

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.

Purpose To investigate the anti-inflammatory effect of Radix Rehmanniae Praeparata(RRP)on the footpad inflammation induced by complete Freund's adjuvant(CFA)in rats.Methods CFA 100 μL were injected subcutaneously to the Wistar rats at the pad of right hindfoots.19 days later,the rats were daily siven RRP water extract(0.625,1.250,2.500 g/kg·bw)or dexamethasone(0.5mg/ks·bw)intragastrically.The changes of body weight and foot volume were measured.The indexes of organ and blood were determined at the 29th day,the foot pad was removed,and routine paraffin section was performed.Results The model rats kept foot swelling and lymphocyte infiltrating,and the platelet number decreased.The other indexes were statistically insignificant when compared to the controls.RRP did not display any anti-inflammatory effect on the swollon foots,but thoracic gland and spleen indexes were rescued,and platelet number and creatinine content were increased by RRP administration in a dose-dependent manner.The anti-inflammation of dexamethasone was conspicuous,but the side effects were also significant.Conclusion RRP may be plays an adjunctive action in herbal recipes to treat rheumatoid arthritis.

For solving the problem that common similarity algorithms are insensitive to the relative differences of different chromatographic fingerprints data, this paper improved the algorithms of improved extent similarity), which named new improved extent similarity. It was confirmed that new improved extent similarity could distinguish) the samples with the same total difference and different distribution of relative differences. by applying) the similarity algorithm to simulated data and the chromatographic fingerprints of nine batches Rukuaixiao tablets. New improved extent similarity could reflect the relative differences of peak areas more sensitively when the relative differences of common peak areas was less than 100%. The result indicates that new improved extent similarity can reflect the large deviation from the established proportion of components, which can be applied to the control of the fluctuation of the established proportion of effective components and the process quality control of Traditional Chinese Medicine .

Objective To analyse the clinical significance of LHRH exciting test in the differential diagnosis of constitutional delayed puberty (CDP) and hypogonadotropic hypogonadism (HH). Methods Eighty-one cases from 1982 to 1998 were investigated and followed up. They were all at genital stage Ⅰ. After injection of 100 ?g LHRH, the blood samples (3 ml) were taken at -15, 0, 15, 30, 45, 60, 90 and 120 min. The serum LH and FSH levels were determined by radioimmunoassay. Then they were followed up every 3-24 months. After they received LHRH exciting test, they were followed up until over 18 years old. According to their puberty development status, they were divided into 3 groups, normal group (n=34),CDP group (n=16) and HH group (n=31),andthemeanage,whenthey received LHRH exciting test, was (10.2?0.9, range 9-14) years, (16.0?1.0, range 14-18) years and (17.1?1.4, range 16-22) years respectively. Results There were no significant differences in serum LH baseline level and peak time in normal, CDP and HH groups, but the serum LH peak level, LH increment (peak LH level minus baseline LH level), LH increment ratio (peak level/baseline level of LH) and the area under LH curve (AUC LH ) of normal group were significantly higher than those of CDP group and HH group (all P
