Traditional Chinese Drug Research & Clinical Pharmacology 2009;20(4):347-349
Objective To establish a HPLC method for determining of the content of palmatine hydrochloride in Fuke Qianjin Tablets. Methods HPLC was performed on Shimadzu-C18 column. The mobile phase consisted of 0.05 mol·L-1 sodium acid phosphate (pH=3, adjusted by phosphoric acid)-acetonitrile (72 : 28). The detection wavelength was at 265 nm. Results The linear correlation was in the range of 0. 051 μg~0. 255 μg(r=0. 999 9). The average recovery was 100. 04 %, and RSD=1.03 % (n=5). Conclusion The method is accurate and specific.

Objective To establish a HPLC method for determining of the content of palmatine hydrochloride in Fuke Qianjin Tablets. Methods HPLC was performed on Shimadzu-C18 column. The mobile phase consisted of 0.05 mol? L-1 sodium acid phosphate (pH=3, adjusted by phosphoric acid)-acetonitrile (72 ∶ 28). The detection wavelength was at 265 nm. Results The linear correlation was in the range of 0.051 ? g~ 0.255 ? g(r=0.999 9). The average recovery was 100.04 % , and RSD=1.03 % (n=5). Conclusion The method is accurate and specific.
3.Clinical trial data validation and user acceptance testing.
Acta Pharmaceutica Sinica 2015;50(11):1480-1484
For pharmaceutical industries, clinical data is one of the most valuable deliverables. It is also the basis of analysis, submission, approval, labeling and marketing of a drug product. To ensure the integrity and reliability of clinical data, a scientific standardized quality control (QC) has to be established at each step of a clinical trial. Data validation is conducted to ensure the reasonability and compliance of clinical data by checking data quality before the data is statistically analyzed. This paper focuses on purpose of data validation, creation of data validation plan, rationale of data validation, types of data validation and performance of user acceptance testing on clinical database.

International Journal of Cerebrovascular Diseases 2012;(11):866-869
Platelet membrane glycoproteins play a key role in the processes of platelet adhesion,activation and aggregation and thrombosis.Many studies have shown that platelet membrane glycoprotein gene polymorphisms are associated with ischemic stroke.This article reviews the relationship between platelet membrane glycoprotein gene polymorphisms and ischemic stroke.

To determine the content of astragaloside IV in Xiao' er Weijining Mixt ure, TCL conditions were optimized by comparing various refined methods. And the y were as follows: the underlayer of CHCl3-CH3OH-H2O(65∶35∶10) below 10 ℃was developed at 15~18℃ and sprayed with 10%H2SO4-C2H5OH,the heating tempe rature was 105℃ for 3~5 min,and λS=400 nm, λR =700 nm.

Half-synthetic oil ester (of fruit of a cubeb litsea tree) Suppositories. The speed of medicine release was 85% within 20min in S-40 Suppositories and nearly 100% within 30 min. Conclusion: S-40 can be used as the ground substance for the antipyretic Suppositories for children.
8.Study on the Standards of Residents′Competency Cultivation in Zhuhai
Chinese Medical Ethics 2016;29(5):755-758
From the view of medical professionals, this paper explored the standards of residents′ competency cultivation in Zhuhai using Delphi method. The research outcome that consisted of 53 factors and 6 dimensions was obtained after two rounds of expert consultation. There are 6 first-level indexes including professionnalism and body-mind quality, clinical practice skill, the competency of lifelong learning and self-improvement, humanistic medicine practice skill, medical knowledge, and the competency of promoting the medical system to develop. As well, there are 18 second-level indexes and 29 third-level indexes. The standards stated that the clinical prac-tice skill would not be the main part of residents′competency cultivation. Qualified residents should reach the na-tional standard of the clinical practice skill but also the other five indexes.

[Objective] To investigate the clinical effects in the treatment of gluteus muscles contracture of small incision insidious lysis and three steps rehabilitative drills.[Method]One hundred and eighteen patients were treated with small incision insidious lysis and three steps rehabilitative drills(treatment group),and fifty-six patents with gluteus maximus lysis(control group)from February 1988 to February 2006.Clinical classification of gluteal muscle contracture,mechanism of crook-lateral and spread-lateral limb cross-leg tests designed by the author,main points of small incision insidious lysis and implement of three steps rehabilitative drills were evaluated.[Result]The cases were followed up for 1~8 years,clinical outcomes were evaluated by the Huang Yao-tian's scoring system.The early clinical effect were evaluated after 45 days of operation.All the results showed statistically significant difference(
10.Vitreous condition of the eye with diabetic macular edema
Chinese Journal of Ocular Fundus Diseases 2003;0(06):-
Objective To investigate the relationship between the posterior vitreous detachment (PVD) and the diabetic macular edema (DME). Methods A total of 169 eyes with DME which were diagnosed by funduscopy,fundus fluorescein angiography (FFA) and optical coherence tomography (OCT) were retrospectively analysed. PVD and partial PVD were detected by OCT and biomicroscopy. The characterizations of OCT images of DME were analysed. Results In 169 eyes, 156 (92.3%) had no PVD with the average thickness of fovea of 297 ?m; 11 (6.5%) had complete PVD with the average thickness of fovea of 229 ?m; 2 (1.2%) had partial PVD with the average thickness of fovea of 347 ?m. Conclusions Only a few PVD were found in DME eyes, so traction of PVD may not be the main cause of DME.
