Aim To study the effect of oxymatrine (OMT)on protecting human umbilical vein endothelial cells (HUVECs)from toxicity induced by high glucose in vitro.Methods The HUVECs were cultured with medium containing different concentrations of glucose or OMT. The cells were randomly divided into 6 groups:5.5 mmol·L -1 control group(Control),22.2 mmol·L -1 high glucose (22.2 mmol·L -1 ),44.4 mmol·L -1 high glucose (44.4 mmol·L -1 ),control+OMT(control +OMT),22.2 mmol·L -1 high glu-cose +OMT(22.2 mmol·L -1 +OMT),44.4 mmol ·L -1 high glucose +OMT (44.4 mmol · L -1 +OMT).The protective effect of oxymatrine was as-sessed by MTS assays.The expression of A2B in HU-VECs was detected by Real-time quantitative PCR (qPCR)and Western Blot methods.Results The glucose was shown to have caused cytotoxicity in HU-VECs.Oxymatrine (3 μmol·L -1 )was found to have protected HUVECs from glucose toxicity effectively, and reduced the expression of A2B significantly.Con-clusion Oxymatrine can obviously protect HUVECs from cytotoxicity induced by high glucose and the effect is performed partly by decreasing A2B expression.

Objective To study Baizhu's inhibitory effect on S180 sarcoma growth and its effect on Bcl-2 expression in tumor-transfected mice. Methods S180 cells were subcutaneously injected into 60 healthy Kunming mice. Meanwhile the mice were dealt with MTX or Baizhu, separately; the weight of tumor was measured in the following two weeks; the expression of Bcl-2 was detected by RT-PCR. Results The tumor's weight in Baizhu group was lower than that in model group, but higher than in MTX group (P<0.05), but Baizhu's inhibition was not associated with its dose (P>0.05), and Baizhu's rate of tumor growth inhibition was lower than that of MTX. Compared with that in control group, Bcl-2 expression was lower in Baizhu group obviously. Conclusion Baizhu can inhibit tumor growth and serve as an adjuvant drug in tumor therapy.

China Pharmacy 2005;0(15):-
OBJECTIVE:To establish a RP-HPLC method to determinate the plasma concentration of paclitaxel in tumor patients.METHODS:Paclitaxel was extracted from plasma with organic phase(ethyl-acetate)by two-step extraction on Tianhe Kromasil C18 column(250 mm?4.6 mm,5 ?m)with a mobile phase consisted of acetonitrile-methanol-water(40∶25∶40)at a flow rate of 1 mL?min-1.The detective wavelength was set at 227 nm and the column temperature was maintained at 35 ℃.RESULTS:The linear range of paclitaxel was 0.05~5.00 mg?L-1(r=0.999 7)with average recovery rate at 98.75%~100.44%.Both intra-day RSD and inter-day RSD were less than 5%(n=5).The plasma concentration-time profile in 11 patients after iv infusion of paclitaxel was in line with a two-compartment model.CONCLUSION:This established method is simple,accurate,reproducible and applicable for clinical determination of blood drug concentration and pharmacokinetic studies.

[Objective]To investigate the clinical value of OCM approach of minimally invasive total hip arthroplasty(MIS-THA).[Method]From February 2005 to December 2006,18 cases of MIS-THA were performed with OCM approach technique.The mini-incision through the intermuscular interval provided a good exposure for total hip replacement,preserved muscle integrity and kept the posterior capsule intact.A two-stage osteotomy of femoral neck was conducted.Specialized acetabular and femoral instruments were applied to fix the prosthesis.[Result]The average length of skin incision was 9.2 cm,the blood loss and drainage were 230 ml and 90 ml,respectively.At 6 months after operation,the mean Harris scores of hip increased from 46.2 to 87.1 for all cases.One case of femoral fracture around prosthesis and one of excessive anteversion were observed.[Conclusion]OCM approach brought satisfactory clinical outcomes when applied in MIS-THA.This surgical technique shows an obvious learning curve,but requires specialized instruments.
7.Application of different colorants in the surgery of idiopathic macular hole
International Eye Science 2017;17(10):1849-1851
Internal limiting membrane ( ILM) peeling is commonly used in the operation of idiopathic macular hole ( IMH ) surgery. The success of ILM peeling has been greatly improved with the assistance of vital dyes. Currently, several kinds of vital dyes such as indocyanine green ( ICG ) , brilliant blue G ( BBG ) are applied in the ILM staining. However, all of the vital dyes have potential toxicity and side effects on the retina. In recent years, many kinds of dyes and staining improved emerge in endlessly. This paper reports the progress in the application of different colorants in the operation of IMH.

Objective: To review the problems existing in the development and application of current electroacupuncture (EA) apparatuses, and provide reference for the development of EA apparatuses. Methods: Related literatures about EA apparatus were derived from China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang) and Chongqing VIP Database (CQVIP) between 2013 and 2017. Literatures about the development of EA apparatuses and the application for experimental research and clinical treatment published in Chinese journals were retrieved, and the development and application of EA apparatuses were summarized. Results: Among the 107 selected literatures, 48 types of EA apparatuses were used, of which only 11 models could be found in the registration list and within the validity period. There was no registration information for the EA apparatus newly developed in the past 5 years. The EA parameters used in experimental research and clinical treatment in Chinese medicine were different, and the combination of stimulation parameters was diverse. Conclusion: At present, most of the new EA products are still in the experimental or research stage, and the transformation of results has not yet been achieved. Moreover, there is no unified standard for the use of EA apparatus and its stimulation parameters in experimental research and clinical treatment, which is not conducive to the standardization process of EA stimulation.

To promote the understanding and practice of evidence-based medicine (EBM) in coronary artery bypass grafting (CABG). The transition of CABG graft materials from saphenous vein to arterial conduits were perceived using the principles of EBM. The arterial conduits were increasingly performed based on the principles and practice of EBM, therefore the postoperatively long-term graft patency rate, survival rate, and free cardiac event rate were significantly improved. CABG outcomes can be significantly improved by using arterial conduits based on principles of EBM.
