AIM To determine the contents of the two free-and conjugated quercetin and genistein in Huaijiao Pills (Fructus Sohorae,Radix Sanguisorbae,Radix Scutellariae,etc.).by RP-HPLC. METHODS HPLC was employed with a column of Diamonsil ODS-C_ 18 (4.6 mm?150 mm,5.0 ?m) and a mobile phase of MeOH-H_2O-HAc(2∶ 3∶ 0.25),the detection wavelength being at 254 nm and the column temperature being at 30?C . RESULTS Nice linear correlation existed, when quercetin was within 0.204 8-1.229 ?g and genistein within 0.532 5-3.192 ?g.The correlation coefficient of each group was 0.999 1 and 0.999 8 respectively.The average recoveries of quercetin and genistein were 99.0 % and 99.1 % ,respectively.The RSDs were 1.02 % and 0.40 % ( n =5),respectively. CONCLUSION With this method,quercetin and genistein in Huaijiao Pills could be determined simultaneously and applicable to the quality control of Huaijiao Pill.

Objective To study the effect of He-Ne laser at lower power on proliferation and differentiation of embryo midbrain nerve cell.Methods The embryo midbrain nerve cell of rat embryo were randomly divided into one control group and three experimental groups.The cells in experimental groups were respectively irradiated at different time:3 min(A组),6 min(B组),10min(C组),each day.After ten days,we counted the concentration rate and determined the content of protein and the amount of superoxide dismutase(SOD)and malonyldialolehyde(MDA).Results The concentration rate of group A and of group B significantly increased than that of the control group(P

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.

A questionnaire survey was conducted in 724 students from three junior high schools in Shanghai Jinshan district.Total 642 students completed the questionnaire with a response rate of 88.7％,among them 75 were overweighted or obese.The positive rate of 6 out 8 unhealthy psycho-behavioral practices related to weight control in overweight or obese students was significantly higher than that of students with normal weight (all P ＜ 0.05).Binary logistic backward stepwise regression analysis showed that overweight or obesity was risk factor for the unhealthy psycho-behavior practices related to weight control in adolescent students.

Objective:To observe the anti inflammatory action of Yangfeihuoxue Decoction and its effects on inflammatory mediums. Methods: The mouse and rat inflammatory models were established by dimethylbenzene, carrageenin and paper strip investing method, and the rat model of pulmonary fibrosis was established by bleomycin. The inhibition of Yangfeihuoxue Decoction on various inflammatory reactions (with swelling rate, swelling degree and height of granuloma as markers) and its effects on levels of histamine (H) and tumor necrosis factor (TNF) in blood were studied. Results: Yanfeihuoxue Decoction can obviously inhibit acute, subacute and chronic inflammatory disease ( P

Objective To study the inductive effect of targeted UVB phototherapy on skin hyperpigmentation and its mechanism.Methods Ten brownish guinea pigs were used to develop experimental models.After depilation,four adjacent areas were selected on the back of each guinea pigs and served as the control,low-dose,moderate-dose and high-dose group to receive targeted UVB irradiation with a cumulative dose of O,2500,3500,4500 mJ/cm2,respectively.After 6-week irradiation,the guinea pigs were sacrificed and skin sampies were obtained.The hyperpigmentation induced by UVB irradiation was estimated by naked eyes,staining for melanocytes(Imokawa method)and melanin granules(Masson-Fontana staining),respectively.Immunohistochemistry was carried out to determine the level of nitric oxide synthase and HE staining to observe epidermal histological changes.Results A statistical difference was observed in the pigmentation score,quantity of melanin granules and dopa-positive melanocyte number among the four groups (P<0.05),and the moderatedose group was higher than the high-dose group in terms of these parameters.The expression of inducible nitric oxide synthase increased in a radiation dose-dependent manner,and the median value for inducible nitric oxide synthase expression level was 0.50,1.25,1.75,2.00 in the control,low-dose,moderate-dose and highdose group,respectively(P<0.05).Conclusions Targeted UVB phototherapy can induce hyperpigmentation of the skin in brownish guinea pigs in a dose-dependent manner,but higher dose may not work better.To irradiate with an initial dose close to or slightly higher than the minimum erythema dose may result in a satisfactory effect with reduced cumulative dose and potential risk for cancer.

Objective To study the method of surgical correction for pelvic obliquity secondary to leg length inequality. Methods Pelvic equilibrium operation is designed to correct the fixed pelvic obliquity, equilibrate the two lower limbs by bilateral iliac osteotomies with transfer of a block of iliac bone from the normal ilium into the abnormal ilium of the contralateral side. This procedure also corrects the associated acetabular dysplasia. Results In this series of 32 patients, none was lost to follow-up. Thirty-two patients, 19 males and 13 females, whose ages ranged from 14 to 34 years with a mean of 22 years, underwent surgery; twenty-four cases had fixed pelvic obliquity and acetabular dysplasia secondary to a short limb following anterior poliomyelitis. The deformities in seven cases were due to severe tuberculous infection in childhood which had resulted in a fixed adducted ankylosed hip. The pelvic equilibrium was caused by trauma in one case. During the review, the minimum time from surgery was 2 years and 6 months, and the maximum 13 years and 6 months with a mean of 6 years and 8 months. The results were excellent. Preoperatively, 29 patients walked on crutches, and postoperatively, 25 patients could walk unaided, one with a stick and three on single crutch. In this paper, we also presented the associated experiment research of pelvic equilibrium operation. Conclusion Pelvic equilibrium operation has been proved to be a new effective surgical correction method of pelvic obliquity secondary to leg length inequality.
