China Pharmacy 2017;28(1):141-144
OBJECTIVE:To provide reference for improving classification management and specifying standards of retail phar-macies in China. METHODS:The implementation status and standards of retail pharmacies'classification management in China were analyzed by using the method of comparative analysis. In view of the effects of classification management on retail pharmacy and its implementation difficulties,corresponding improvement measures were put forward. RESULTS & CONCLUSIONS:There are difference in the implementation status and standards of retail pharmacies'classification management in the national provinces and cities. Since the implementation of pilot in 2007,the main effects include retail pharmacies facing the survival of the fittest whipsaws pattern,the remote township small retail pharmacies facing a transition;the main implementation difficulties include gov-ernment failing to give a full propoganda the classification management of retail pharmacies,the construction of licensed pharma-cist team to be strengthened. It is suggested to include the ability of pharmaceutical care and credit level into the standard,imple-ment dynamic management,and complement classification management of retail pharmacies with the construction of licensed phar-macist team.
2.Bone marrow imaging and the application in the hematologic system
Journal of Leukemia & Lymphoma 2010;19(12):758-760
Bone marrow scintigraphy is a technology which is used in bone marrow mononuclear phagocytes may swallow colloidal imaging agent which is injected by intravenous, and the red bone marrow hematopoietic cells are consistent with mononuclear phagocytes. So it can indirectly observe the red bone marrow distribution. This technology can overcome disadvantage of the traditional biopsy which can only be partially drawn and can provide functional body imaging of bone marrow, simple and noninvasive. So it is used widely in the treatment of disease in the blood disease.

4.Screening and application of drug-eluting stents in patients with cardiovascular diseases
Chinese Journal of Tissue Engineering Research 2016;20(38):5770-5776
BACKGROUND:Drug-eluting stents have achieved better treatment outcomes, but late stent thrombosis shakes its status. With the development of drug-eluting stents, loaded drugs are the key to reduce stent thrombosis. OBJECTIVE:To analyze the screening and application of drug-eluting stents. METHODS:A computer-based search was performed for literatures published from 2010 to 2016 in databases of PubMed and WanFang using the keywords of“drug eluting stents;rapamycin (sirolimus);paclitaxel;heparin;zotarolimus;everolimus”in English and Chinese, respectively. According to inclusion and exclusion criteria, 30 eligible literatures were included for analysis. RESULTS AND CONCLUISON:An ideal drug-eluting stent can selectively inhibit vascular smooth muscle and is expected to be anti-coagulated, but makes no effects on vascular endothelial cel s or promoting the cel proliferation. Most of the loaded drugs are antithrombotic and anti-proliferative drugs, among which, rapamycin-eluting and paclitaxel-eluting stents are extensively used. Regardless of delaying the proliferation of vascular endothelial cel s and increasing the thrombosis risk, most of drug-eluting stents are stil loaded with these two drugs, and only few stents loaded with rapamycin derivatives, such as everolimus, zotarolimus, tacrolimus and pimecrolimus. Current research focuses on developing a stent with rapid drug releasing and anti-proliferative capacity. Meanwhile, the combination of drugs and biphasic releasing are another novel idea.
6.Effect of Mcl-1 siRNA on TRAIL-induced apoptosis in gastric cancer cells
Acta Universitatis Medicinalis Anhui 2016;51(1):47-51
Objective To explore the effect of Mcl-1 small interference RNA ( siRNA) on tumor necrosis factor-re-lated apoptosis-inducing ligand ( TRAIL)-induced apoptosis in gastric cancer HGC-27 cells. Methods The apop-totic rates of cells treated with TRAIL and pan-caspase inhibitor ( z-VAD-fmk) alone or combination were measured by propidium iodide (PI) method using flow cytometry. The activation of caspase-3, cleavage of PARP-1, as well as the protein level of anti-apoptotic Bcl-2 proteins Bcl-2, Bcl-XL and Mcl-1 before and after TRAIL treatment were monitored by Western blot analysis. Transfection of Mcl-1 siRNA was performed using Lipofectamine 2000 reagent. The efficiency of gene silencing was quantified by Western blot and the effect of Mcl-1 siRNA on TRAIL-induced apoptosis was measured using PI method. Results HGC-27 cells were resistant to TRAIL-induced apoptosis, and z-VAD-fmk pretreatment could block apoptosis nearly completely. Activation of caspase-3 and cleavage of PARP-1 occurred in the late stage of apoptosis. The expression levels of Bcl-2, Bcl-XL and Mcl-1 were not altered after exposure to TRAIL. Transfection with Mcl-1 siRNA could obviously downregulate the expression evel of Mcl-1 in HGC-27 cells and enhanced the sensitivity of cells to TRAIL-induced apoptosis. Conclusion Overexpression of Mcl-1 may account for the resistance of HGC-27 cells to TRAIL.ownregulationof Mcl-1 by siRNA can effectively enhance the sensitivity of HGC-27 cells to TRAIL-induced apoptosis.
7.Cross-talk and molecular mechanisms between NMDA receptor and opioid receptor in opioid dependence
Chinese Pharmacological Bulletin 1987;0(01):-
Opioid dependence is based on compensatory adaptations in neurons following chronic exposure to opioids. Recent researches show antagonists of N methyl D aspartate (NMDA) receptors inhibit physical and psychic dependence on opioids. This review focuses on the interactions between opioid receptor system and NMDA receptor system, and on the molecular mechanisms of NMDA receptor contributing to opioid dependence. The clinical prospects of NMDA receptor antagonists and related substances on preventing and treating opioid dependence are aslo discussed.
8.The Clinical Features of the Sick Sinus Syndrome in Elderly Patients
Journal of Chinese Physician 2002;0(S1):-
Objective To Study the clinical characteristics of the :sick sinus syndrome,(SSS) in elderly patients.Methods The disease onset age and causes, natural course and symptoms,dynamic electrocardiography(DCG) and cardiac pacing occasion were reviewed and analyzed. in 50 elderly patients had the diagnosis of SSS.Results The morbidity of SSS had increased significantly in elderly men over 70 years. The ordinary causes were coronary heart disease (CHD),specific SSS and the hypertensive heart disease,cardiomyopathy; and degenerative valvular heart disease etc.The mean natural course were about 10 years.The course of DCG type III was the longest one and the type IV was the shortest. The early symptoms were palpitation, dizzy and weakness,and the late symptoms were transient amaurosis, syncope and the worse cardiac angina and heart failure .The cardiac pacing was predicated by the clinical symptom's severity, which was determinated by both of the severity of bradycardia or sinus arrest and the patient's ability of compensation and adaptation.DCG was the commonly used diagnostic method for SSS in elderly patients.Conclusions The SSS has high incidence in elderly men over 70 and is caused by kinds of deasese,such as CHD and specific SSS,etc.The course is frequently intermittent,hide and very long the disease course. The early symptoms and DCG are atypical. The late symptoms commonly are transient amaurosis and syncope .and the late DCG has four types.The cardiac pacing was predicated by the clinical symptom's severity and DCG was the commonly used to diagnose SSS in elderly patients.
9.ECV304 cells can be used as a general model, tool or target in the re search of biomedicine and pharmacology
Chinese Journal of Pathophysiology 1986;0(01):-
ECV304 was reported first in 1990 as a spont aneously-transformed and immortalized cell line derived from a Japanese HUVEC. S ubsequently, many studies validated that the ECV304 is a permanent endothelial cell line. It has been used widely as an endothelial cell model and an useful re search tool in biomedicine and pharmacology. However, several distinct differenc es exist between ECV304 and HUVEC. Some studies even pointed out that ECV304 is not of HUVEC origin. According to the research data including ours, this reporte dly endothelial-derived permanent human cell line ECV304 may be dedifferentiated towards an epithelial phenotype. It is therefore not an appropriate cell line t o study endothelial cell biology. But cultured ECV304 cells can still be used as a model, tool or target in the pathophysiological and pharmacological studies, depending on whether or not their functional expression or markers are suitable for the research work.
