Objective To establish a high performance liquid chromato-graphic method for determining the concentration of baicalin in healthy volunteers.Methods The assay was conducted on the Agilent HC-C18 (250 mm × 4.6 mm,5 μm)column with methanol-acetonitrile-phosphoric acid (47 ∶ 53∶0.2)as the mobile phase.The detection wave length was set at 280 nm,and wogonin was taken as the internal standard.Results The linearity range was 0.25～ 12.0 μg/ml with a regressive equation of Y=0.0094 C-0.00175 (r=0.9997).The recovery was above 80％,with both intra-day RSD and inter-day RSD below 10％.Conclusion The method was convenient,rapid,accurate,and suitable for the pharmacokinetic study of baicalin and monitoring its concentration of clinical application.

Congenital heart disease (CHD) is the most common defect in human.The genetic basis of CHD is rather complicated.Chromosome aberrations,single gene disorders and polygenic disorders are three known genetic mechanisms that are responsible for cardiac malformations.Recently,with the application and development of molecular genetic approaches in CHD,significant advances in the understanding of the pathogenesis of cardiac malformations are being made.

Concerning the principal individual medical financing responsibility,Singapore provided well medical insurance for low-income groups through the general shared medical subsidy system and the medical assistance system based on income examination.Based on the whole framework of medical insurance system,it analyzed the structure and main content of the all-dimension and multi-tiered medical assistance system in Singapore.It provided references for the medical assistance development in China,including rationally define the scope of medical assistance,respond the outpatient demand and adjust the ageing social development;implementing designated medical institutions treatment systems,especial for primary institutions:introducing social forces during the management of medical assistance.

Embryonic stem cells(ESCs)are pluripotential cells,and they can be induced to differentiate into bone cells,cartilage cells,muscle cells,blood vessels and neurogenesis cells.In addition,ESCs are able to participate in the regeneration of ocular surface.At present,many research groups,domestic and abroad,have reported that ESCs can not only differentiate into corneal epithelium-like cells,but also play an important role in the repair of corneal epithelium.However,other unsolved problems in ESCs-related corneal tissue engineering are being concerned,such as the molecular biologic mechanism underlying the directional differentiation from ESCs to corneal cells,and the potential tumorigenicity with grafting of transformed or undifferentiated ESCs.The purpose of this review was to provide a summary of research progress in the differentiation of ESCs into corneal epithelial cells.

Pulmonary embolism or pulmonary vein thrombosis is rare in children but does occur.Compare to adults,the vast majority of children with PE have risk factors.The clinical manifestation includes shortness of breath,pleuritic chest pain,and hemoptysis,however,which are not specific.The majority of evidence for treatments in the pediatric population is extrapolated from adult populations; the choice of treatment should be guided by risks and benefits,underlying disease,and especially,the hemodynamic stability of the patient.This article reviews the current knowledge of pulmonary embolism and pulmonary vein thrombosis in the pediatric population,summarizing its characteristics from epidemiological aspects to diagnostic and therapeutic relevant issues.

Objective To study the impacts of health insurance schemes on the equity of health services access and the financial protection for disease risk exposure of the elderly population.Methods The descriptive statistics method and econometrics models.Results Full coverage of the health insurance fails to eliminate the inequity in health services access.For example,the two-week clinical visit rate and hospitalization rate of the high-income group are 1.57 and 1.21 times higher than those of the low-income group;the disease risk economic protection function of the health insurance falls below requirement,as the out-of-pocket ratio is as high as 30%~40%;the security for urban workers is far better than urban residents,as the utilization level of outpatient service and hospitalization service of senior workers are 1.18 and 1.33 times that of senior urban residents respectively.Conclusion Despite the full population coverage of health insurance schemes,it is a long way to go before the goal of universal health coverage. Future reforms should aim at filling the financial gaps between different health insurance schemes.

Through observation on changes of inflammatory mediators and hemorrheology among chronic prostatitis patients before and after treatment, this study was aimed to compare the therapeutic differences between the applications of standard retention enema ofQu-Yu Tong-Bi (QYTB) decoction andα-blockers combined with quinolones. During the same period, 164 patients of the Henan Province of Traditional Chinese Medicine Hospital were randomly divided into the observation group and control group, with 62 cases in each group. Retention enema of QYTB decoction was given in the observation group; andα-blockers combined with quinolones were used in the control group. The treatment course was one month. And the differences were compared. The results showed that the total effective rate of the observation group was 79.03% (49 cases); and that of the control group was 61.29%(39 cases). There was statistical significance between two groups (P < 0.05). There was statistical significance on TNF-α, IFN-γ and NIH-CPSI score comparison before and after treatment of two groups (P < 0.05). Compared to the control group, the posttreatment TNF-α, IFN-γ and NIH-CPSI score in the observation group had significant difference (P < 0.01). There were no significant differences on the whole blood viscosity (high shear), plasma viscosity and erythrocyte deposited test value contrast between pretreatment and posttreatment in the control group. There were significant differences on the whole blood viscosity (high shear) and plasma viscosity between pretreatment and posttreatment in the observation group (P < 0.05). However, there was no significant differences on erythrocyte deposited test value contrast. It was concluded that both methods had certain therapeutic effect in the treatment of chronic prostatitis. However, the effect of retention enema of QYTB decoction was better than the treatment of quinolones combined withα-blockers.

AIM: The metabolites of scutellarin were studied in gastrointestinal tract.METHODS: Scutellarin was hydrolyzed with hydrochloric acid and ?-glucuronidase.Human intestinal flora and scutellarin were incubated in vitro.The metabolites were identified by UPLC-MS/MS method.RESULTS: Scutellarin could be hydrolyzed with hydrochloric acid and ?-glucuronidase,and could be metabolized by human intestinal bacteria.A main metabolite,scutellarein,also was found in the plasma of healthy volunteers after oral administration.CONCLUSION: There were scutellarin and scutellarein in intestinal before absorption.It was suitable for scutellarin pharmacokinetic studies to determine scutellarein or total aglycone.

Objective:To evaluate the effect and toxic side-effect of paclitaxel combined with cisplatin(TP regiment) chemotherapy in treatment of pulmonary metastasis tumor.Methods:Forty tumor patients with pulmonary metastasis accepted chemotherapy by paclitaxel 135mg/m~2 infusion intravenous on d1,and cisplatin 25mg/m~2 daily on d2～4.Each treatment cycle was four weeks.Each patient received more than 2 courses of treatment.Results:In 40 patients,7 were with complete response (17.5%)and 18 were with partial response(45%),the complete remission and partial remission(CR+PR)was 62.5%;The disease kept stable in 11 case(27.5%)and progressed in 4 case(10%).The median time to tumor progression was 6.0months, and the median actuarial survival was10.0 months.The most common toxic side-effects were myelosuppression and alopecia. Conclusion:The combined chemotherapy of paclitaxel and cisplatin is good short-term efficacy in treatment of pulmonary metastasis tumor.The toxic side-effects are tolerable and mild.
