Objective:To develop an HPLC method for the determination of valacyclovir hydrochloride capsules. Methods: An Inertsil ODS (250 mm × 4. 6 mm,5μm) column was employed with methanol-0. 02 mol·L-1 potassium dihydrogen phosphate solution (20∶80) as the mobile phase, the flow rate was 1. 0 ml·min-1, the detection wavelength was at 251 nm, the column temperature was 30℃,and the sample size was 20μl. Results:The linear range of valacyclovir hydrochloride was 2-40μg·ml-1 , the correlation coeffi-cient was 0. 999 9 and the average recovery was 99. 8%(RSD=0. 16%,n=9). Conclusion:The analytical method is simple, accu-rate and special, which can be used in the content determination and quality control of valacyclovir hydrochloride capsules.
2.Uncertainty of target volume and organ at risk during fractional radiotherapy
Journal of International Oncology 2008;35(5):355-358
Anatomic structures and their relative position of the target and organs at risk surrounded will change more or less during fractional radiotherapy.These uncertainties will affect the practice of treatment planning correctly.The degree of these uncertainties can be investigated by imaging verification system during clinical practice.The possible reasons of these uncertainties may be tumor volume variations,organ motions orshape changes,patients weight or form changes and set-up errors.The development and practice of imageguided radiotherapy,dose guided radiotherapy and adaptive radiotherapy can offer rational approaches to over-come the uncertainties of the target and organ at risk surrounded during radiotherapy.
3.Empirical Analysis the Competitive Effects of Profit-making Hospitals
Chinese Health Economics 2014;(1):73-75
Objective: From the two prospective of hospital quantity and hospital market shares, to analyze the influences of profitmaking hospital’s competition on medical expenses and medical quality. Methods: The sample of provincial panel data from 2003 to 2011 is used, the fixed effect model is applied. Conclusion: For the competitive effect, the expanding of relative scale of profit-making hospitals increased outpatient expenses and reduced hospitalization expenses; for the quality effectiveness, the expand of relative scale of profit -hospitals improved the quality of outpatient service; the simple increase of the quantity of profit -making hospitals had no significant influences on medical expenses and quality of medical care.

5.TAKING THE MACRO FINANCE IDEAS AS THE GUIDE TO BUILD A NEW NORMAL FOR HOSPITAL FINE MANAGEMENT
Modern Hospital 2015;(10):130-131,133
Financial departments of hospitals should widen their horizons .Workers responsible for financial affairs should transform their functions and make the transition from the traditional business accountants to the value managers.The idea of macro financeis proposed in this paper to penetrate the financial ideas into every economic and business activity, every element of the workflows and every member of the staff .In practice, fine management of hospitals can be done jointly by using information platforms , employing financial management tools and organizing ef-ficient financial teams .By doing this , both financial management and operation efficiency of hospitals can be im -proved continuously .
6.The Bias Estimated and Comparative Research for two Kinds of Cholesterol Reagents
Journal of Medical Research 2006;0(11):-
Objective Estimating the determined result bias of two kinds of Cholesterol reagents,in order to research Comparability of results between different reagent method.Methods According to the file of NCCLS EP9-A of America,take 8 clinical serum samples every day,which conclude high、middle and low result samples,analyze each samples twice a day for 5 days,recorded results,analyzed the statistics.,to evaluate the bias estimation of two kinds reagents.According to contrast results,calibration for antomation system(c.f.a.s)taking two kinds calibration cost and using mixed human serum as calibration article,perform the same procedure described above but add 10 samples everyday.which conclude high、middle and low result samples,then statistics analysis was performed.Results The bias rate of two kinds reagents was 5.3%,the difference was statistically significant(P 0.05).Conclusions When changed regent or c.f.a.s in a clinical serum sample comparison experiment,for Cholesterol reagents from different company,c.f.a.s cannot take single calibration values,and cannot emendate the values of calibration serum only by the reply result from a single external quality assessment.Taking the mixed human serum calibrated by reference method as calibration values,which values can correct the determined bias caused by different regent.
7.Role of PET-CT in diagnosis of lung cancer
Chinese Journal of Practical Internal Medicine 2001;0(02):-
Lung cancer is one of the most common malignancies that are life-treatening to human beings.It ranks the first both in morbidity and mortality of malignant tumors.Early diagnosis,accurate staging,proper treatment and improvement of prognosis are the focuses of related studies in recent years.Imaging diagnosis is the main method for diagnosis of lung cancer.The development of imaging diagnosis and the application of advanced techniques such as CT scan,low-dose helical CT scan,MRI,PET and PET-CT ,play a great role in early diagnosis and staging of lung cancer.Recent researches have demonstrated that ET is one of the most efficient non-invasive methods for diagnosis of lung cancers.However,PET has limitation in precise location of the focus.PET-CT integrates the functions of CT and PET together,and is able to locate the focus precisely.This article mainly reviews the value of PET-CT in the diagnosis of lung cancer.
8.Estimation on the Relationship between Personal Health Expenditure and Economic Growth in China Based on the Logistic Smooth Transition Regression Model
Chinese Health Economics 2014;(4):13-14
Objective: To describe the non-linear relationship between out-of-pocket ( OOP ) payment and economic growth . Methods: Using logistic smooth transition regression model to analyze the impact of government health expenditure on the non-liner relationship between OOP payment and economic growth. Results:The impact of economic growth on OOP health expenditure is divided into 3 stages:from 1978 to 1996, the influence of economic growth on out-of-pocket payment approaches to highly-efficient mechanism operation;from 1997 to 2008 belongs to the transition period, it stays as low-efficient mechanism operation since 2009. Conclusion: To continue deepening the medical and health system reform and reduce the burden of personal health expenditure.
9.Effect of rivaroxaban on HIF-α, P-selectin and TNF-αin patients with lower extremity venous thrombosis
Chinese Journal of Biochemical Pharmaceutics 2015;37(7):82-84
Objective To investigate the effect of rivaroxaban on HIF-α, P-selectin and TNF-αin patients with lower extremity venous thrombosis.Methods 41 cases from May 2014 to February 2015 were selected and randomly divided into two groups, 21 cases in the control group were treated by routine treatment, 20 cases in the experiment group were treated on the base of the control group with ivaroxaban.Serum HIF-α, P-selectin and TNF-αwere detected before and after the treatment.ResuIts Compared with the control group, the clinical effect were higher ( P<0.05 ) , the adverse reactions occur rate was no difference (P>0.05).HIF-α, P-selectin and TNF-αwere lower(P<0.05),HIF-αwas positively correlated with TNF-α(r =-0.468,P<0.05), and was not correlated with P-selectin, P-selectin was not associated with TNF-α.ConcIusion Rivaroxaban can effectively improve the lower limb venous thrombosis in patients with clinical symptoms, reduce serum HIF-α, P-selectin and TNF-αexpression, has better clinical curative effect, for clinical treatment of lower limb venous thrombosis has important significance.
10.Analysis of the Total Health Expenditure in China Based on the State Space Model
Chinese Health Economics 2014;(3):50-51
Objective: To predict the growth trend of total health expenditure in China based on the dynamic relationship between total health expenditure and economic growth. Methods: First, analyze the relationship between total health expenditure and economic growth from 1978 to 2011 with the state space model, evaluate the accuracy of the model and predict total health expenditure range from 2012 to 2016 with the status space mode. Results: Up to 2016, the total health expenditure would reach to 5.681 trillion yuan, and the ratio of the expenditure to gross domestic product(GDP) would increase to 5.692%. Conclusion: It is needed to balance the relationship between total health expenditure and economic growth.
