To discuss the distribution of patents' holders for Chinese herbal compounds in treating cardiovascular and cerebrovascular, the patents' holders for Chinese herbal compounds in treating cardiovascular and cerebrovascular were cluster analyzed by means of simple statistics and cluster analysis. Clustering variables were composed of patent applications, patent maintained number, related papers' quantity, etc. Chinese herbal compound patents' holders were divided into four categories according to their different scientific research and patent strength. It is the magic weapon for Chinese herbal compound patents' holders that have scientific research patents' transforming and make coordination of patent protection and scientific innovation.

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.

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 compare the clinical efficacy and safety of continuous subcutaneous insulin infusion (CSII) and multiple subcutaneous insulin injection (MSII) in elderly patients with severe type 2 diabetes.Methods Thirty-seven elderly patients with severe type 2 diabetes in the hospital intensive care unit (ICU) were divided into observation group (19 cases) and control group (18 cases) by random number table method.The observation group was treated with continuous subcutaneous insulin recombinant human insulin lispro injection,and control group was treated with recombinant human insulin lispro injection before meals and at bedtime routine insulin glargine subcutaneous injection.Two groups of patients and their families were given diabetes education.Changes in blood glucose,insulin dosage,blood glucose control standard time,rate of hypoglycemia and hospitalization time between 2 groups before and after treatment were compared.Results After treatment,fasting blood glucose in observation group was (7.2 ± 1.2) mmol/L,2 hour postprandial blood glucose was (9.4 ± 1.2) mmol/L,bedtime blood glucose was (9.4 ± 1.3) mmol/L; which in control group was (8.5 ± 3.0),(10.0 ± 2.4),(10.2 ± 2.4)mmol/L respectively.Fasting blood glucose,2 hour postprandial blood glucose and bedtime blood glucose significantly decreased after treatment in two groups,but there was significant difference between 2 groups (P ＜ 0.05).Blood glucose control standard time in observation group was (5.4 ± 2.5) d,insulin dosage was (43 ± 9) U/d,in control group was (12.8 ± 3.8) d,(55 ± 10) U/d respectively,and there was significant difference (P ＜ 0.05).Observation group had no hypoglycemia.Conclusion CSII for elderly patients with severe type 2 diabetes has better curative effect and security than MSII,and is more conducive to the control of blood glucose and the improvement of the condition.

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 explore the clinical characteristics of neonatal-onset carbamoyl phosphate synthetase I deficiency (CPS1D). Methods Clinical data and result of genetic detection of one neonate with CPS1D were retrospectively analyzed. The pertinent literature was reviewed. Results A 3-day old girl, with onset symptoms of nonspecific performance, such as poor feeding, less activity, tachypnea, and seizures. After fasting, anti-infection, and respiratory support etc. the condition was improved. However, the condition deteriorated and developed rapidly after feeding restarted. MRI showed extensive cerebral white matter lesions. Blood ammonia?>?500 μmol/L. Gene detection found two heterozygous mutations in pathogenic gene CPS1 in twentieth exon of c.2407C?>?G (p.803, R, G) and fourth exon C.323G?>?A (p.108, G, E), according to which CPS1D was diagnosed finally. Conclusions For neonate with normal birth, had feeding difficulty, seizures, and consciousness disorder after establishment of normal feeding, if blood ammonia level significantly increased, the blood and urine amino acids analysis and gene detection should be performed to confirm the diagnosis.
