Objective: A method for determination of glycyrrhizine and paeoniflorin in Fubao Danggui Jiao by RP HPLC was established.Methods: Shim pack CLC ODS column was used with TBAH solution (10→300) methanol (36∶64) (pH=6.0) as a mobile phase for glycyrrhizine and acetonitrile water (containing 0.1% phosphoric acid) (15∶85) as a mobile phase for paeoniflorin. The detection wavelength was at 254nm and 230nm, respectively. The flow rate was 1mL?min -1 .Results: A good linearity was found at the concentration range of 100 1000ng for glycyrrhizine and paeoniflorin. The average recovery was 98.37%,97.44% and the relative standard deviation was 0.32%,0.48%, respectively.Conclusion: This method was simple,accurate,rapid,sensitive and reproducible. The RP HPLC could be used for quality control of Fubao Danggui Jiao preparations.

Promotion of outstanding people to head nurses is key to hospital nursing management.In view of the current shortcomings in the analysis of appraisal data and the interpretation of appraisal results,the analysis of means(ANOM)method is introduced to the process of hospital human resource management.The proposed method aims to solve the problem when the score differences between interviewers are great and the score differences between candidates are small.An example for head nurses' promotion appraisal in a hospital is offered to demonstrate that statistical tools can provide the decision support for hospital personnel selection.Finally,the application differences between ANOM and analysis of variance(ANOVA) in human resources appraisal are compared.

Objective To develop a new method for Tinospora sagittata species identification and genetic map construction. Methods Sequence-related amplified polymorphism (SRAP) was applied for T. sagittata to carry on PCR amplification of its DNA and optimize the reaction parameter grade by grade. Results The stable and reproducible SRAP reaction system of T. sagittata has been developed. Conclusion SRAP is an effective method for T. sagittata identification in molecular degree and it has set up a foundation for the further species identification and genetic map construction of T. sagittata.

Objective To compare the efficacy of contrast-enhanced ultrasound (CEUS) and enhanced CT (CECT) in differential diagnosis of benign and malignant space-occupying lesions of gallbladder.Methods The clinical data of 68 cases of space-occupying lesions of gallbladder confirmed by surgery and biopsy were retrospectively analyzed.The diagnostic accuracy,sensitivity and specificity of CEUS and CECT were analyzed and compared.Results In a total of 68 cases of space-occupying lesions of gallbladder,31 cases were benign lesions and 37 were malignant lesions (gallbladder cancer).For the benign lesions cases,CEUS and CECT were mainly hyper-enhanced in the early stage of enhancement,which were 90.3％ and 83.9％,respectively.In the late stage of enhancement,they were mostly low-enhanced,which were 93.5％ and 87.1％,respectively.For the gallbladder cancer cases,CEUS and CECT were predominantly hyper-enhanced in the early stage of enhancement,which were 94.6％ and 89.2％,respectively,and were all low-enhanced in the late stage of enhancement.In the differential diagnosis for benign and malignant space-occupying gallbladder lesions by CEUS,the differences in peak time,extinction time,peak intensity and average transit time were statistically significant (all P＜0.01).The inhomogeneous enhancement rates were 41.9％ and 48.4％ respectively for CEUS and CECT in the benign lesions cases,and 94.6％ and 91.9％ in the gallbladder cancer cases.Besides,the incomplete gallbladder wall rates are 89.2％ and 91.9％ in the gallbladder cancer cases.However,these differences were all not statistically significant (all P＞0.05).In the diagnosis of benign and malignant lesions cases,the diagnostic accuracy of CEUS and CECT were 92.6％ and 89.7％,the sensitivity was 93.5％ and 90.3％,and the specificity was 89.2％ and 83.8％,respectively,but the differences were not statistically significant (all P＞0.05).Conclusion CEUS and CECT have comparable efficacy in differential diagnosis of benign and malignant space-occupying lesions of gallbladder.CEUS has advantages over CECT and is worthy of extensive clinical application and promotion.

Objective In this study,we explored the role of combination of autophagy inhibition and anti-VEGF in proliferation,migration and tube formation of mouse retinal vascular endothelial cells(RVECs). Methods Well cultured mouse RVECs were randomly divided into four groups:autophagy inhibition group(add-ing autophagy inhibitor 3-MA),anti-VEGF group(adding anti-VEGF-A neutralized antibody),autophagy inhibi-tion+anti-VEGF group(adding the two reagents)and the control group.All cells were then cultured in the hypoxic condition. The cell proliferation,migration and tube formation were detected by EdU,transwell and matrigel as-say,respectively. Results The cell proliferation rate,number of migrated cells and number of tube formation of the other three groups decreased when compared with the control group.These data above in autophagy inhibition+anti-VEGF group were all significantly less than 3-MA group and anti-VEGF group. Conclusion Combination of autophagy inhibition and anti-VEGF may be more effective than simple anti-VEGF in inhibition of retinal neovascu-larization.
