Metabolic syndrome( MS) is a group of clinical symptoms,which is based on the pathophysiol-ogy of insulin resistance that mainly includes obesity,hyperglycemia,hypertension,dyslipidemia,nonalcoholic fatty liver disease and other components.In recent years,many studies have suggested that the occurrence of colorectal cancer( CRC) is closely related with the MS components.This article reviews the research progress on the associa-tion between the major components of MS and the pathogenesis of CRC.

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.
