OBJECTIVE To study the mechanism of loganin,the effective componet of Cornus officinalis,on protecting the glomerulus mesangial cell (GMCs) injured by advanced glycation end products (AGEs).METHODS GMCs were divided into control,model (AGEs: 200mg/L),loganin (0.1,1,10μmol/L) groups.The cell proliferation,FN and COL-Ⅳ secretion,microstructure lesions,RAGE,SphK1,S1P and TGF-β protein expressions were measured.RESULTS AGEs induced cell proliferation,FN and COL-Ⅳ secretions,microstructure lesions,RAGE,SphK1,S1P and TGF-β protein expressions were suppressed by loganin.CONCLUSION Loganin can improve the AGEs induced GMCs injury by regulating the AGEs/RAGE/SphK1 signal pathway,and then ameliorate the diabetic nephropathy.

The external medicine is an indispensable treatment of traditional Chinese medicine (TCM) surgery.The application of Hg is one of the characteristics of TCM surgery medicine for external use.This paper analyzes the present situation of clinical application of Hg and summarizes the common adverse reactions in the literature.The focus of the research on the development of new drugs containing Hg in traditional Chinese medicine is discussed.

Traditional Chinese medicine (TCM) for external use in the treatment of surgical disease has good clinical effect and security,even played a unique effect.At present,surgical department of TCM lack of external application drug.The hospital's own production of external use drug cannot meet the clinical needs,seriously restricting the development of surgical department of TCM.Under the background of attaching great importance to new drug innovation research and development in our country,in the caseof clinical demand of external application drug increases year by year,it is imperative to promote external application drug research and development.This article summarizes the clinical application situation of external application drug,sums up the opportunity and the challenge of new drug research and development,analyses the difficulties and problems in research and development,and the countermeasures were discussed.

Influenza (hereinafter referred to as "flu") guidelines is spe cifically defined to guide the clinical research for new drug of traditional Chinese medicine and the technical standards that the manager,applicant and researcher shall abide by.This article discusses the revision status of flue guidelines for a better understanding and aims to play a guiding role in the research for the new drug development of traditional Chinese medicine.

Traditional Chinese medicine (TCM) orthopedics formula is an important part of the prevention and treatment of orthopedics disease,which has curative effect and the advantages of the whole regulation,but it needs to strengthen its clinical development and reasonable application in clinical.In this paper,by reviewing the current clinical present situation and some problems of the research and development about the TCM orthopedics formula,research and development direction were put forward:the source of prescription,the change of disease spectrum,the clinical location,the apphcation of toxic drugs and animal materials,and the quality control of clinical trials should be paid attentions to,hoping to provide some thoughts for the research and development of TCM orthopedics formula.

Diabetic foot ulcer (DFU) is one of the serious complications of diabetes.With high disability,high amputation rate,serious harm to the physical and mental health of diabetes patients.Traditional Chinese medicine drugs for external use has a certain effect and advantages for treatment of DFU.In this paper analyzes the clinical characteristics of DFU and the status of external drug application,and the necessity of research and development of traditional Chinese medicine for DFU treatment.In the article pointed out the difficulties and of the concerns in process of clinical trials for the DFU traditional Chinese medicine research and development.The preliminary recommendations are given in this article.

Knee osteoarthritis (KOA) is a clinical common and frequent ly-occurring disease,traditional Chinese medicine (TCM) and Chinese medicine have certain advantages for patients in the treatment of early-middle period KOA.In this paper,by reviewingthe clinical feature,evaluation methods and present status of treatment of KOA,the evaluation of traditional Chinese medicine of KOA was proposed.the disease characteristics and clinical localization and clinical characteristics of TCM should be paid attention to,so as to select the evaluation method that can reflect the treatment of characteristics.

Objective The impact of late incomplete stent apposition(ISA)post sirolimus eluting stent(SES)implantation in patients with acute coronary syndrome(ACS)on long-term clinical outcomes remainB controversial.The alm of the present study was to eva]uate the association between late ISA and clinical outcomes in patients with ACS compared with that with stable angina(SA).Methods From February 2005 to March 2007,54 ACS patients and 83 SA patients were enrolled in this study,late ISA was determined by meallS of threc-dimensional volumetric intravaaculair ultrasound(IVUS)analyses one year after SES implantation and clinical outcomes one year post IVUS were obtained in these patients.Results In 219 treated lesions of the 137 patients,late ISA wag documented in 25 lesions in 16 patients(20 ISA in 12 ACS patients vs.5 ISA in 4 SA patients,P＜0.001).Thoush lunlen area in reference and stented segment,neointimal hyperplasia(NIH)area and percentage of NIH in stented segment,and external elastic membrane(EEM)area in reference segment were similar between two groups,EEM area in stented segment [(15.34±5.44)mm2vs.(13.83±4.51)mm2,P=0.026],stented/reference segment EEM area ratio (1.13±0.22 vs.1.02±0.18,P＜0.001),plaque and media area[(8.43±3.93)mm2vs.(7.01±2.93)mm2,P=0.002]was significantly lager in ACS group than that in SA group.Multivariable logistic analysis showed that ACS(OR 6.477 with 95%CI from 2.297 to 18.263,P＜0.001)and stent length≥23 mm(OR 3.680 with 95% CI from 1.181 to 11.469,P=0.025)were main independent factors of occurrence of late ISA.Incidence of main adverse cardiac events(MACE)one year post IVUS Wag similar between the two groups.Conclusion Compared with patients with SA,ACS patients had larger stented segment EEM area,plaque and media areaas well as increased incidence of ISA.However,the incidence of MACE was similar in ACS and SA patients one year after IVUS.

Objective To investigate the status quo of smoking cessation and analyze factors influencing smoking cessation in cigarette smoking patients with coronary artery disease(CAD).Method A total of 350 smoking patients with CAD was surveyed by questionnaire,logistic regression analysis was performed to analyze factors influencing smoking cessation.Results Incidence of smoking cessation was 57.1%(200/350)in this cohort.Patients were divided into two groups,the elderlv(>65 years old,n=111)and the young group(≤65 years old,n=239).The smoking cessation rate in the elderlv group is significantly higher than in the young group(71.2%vs.50.6%,P<0.001).Aged patients and patients with high cultural level are easier to give up smoking.Logistic analysis showed that age≤65 years old (OR=2.336,P=0.004),low cultural level(OR=1.310,P=0.028),PCI(OR=0.261.P<0.001).coronary artery bypass graft(OR=0.107,P=0.004),total family income>4000 RMB/month (OR=1.828,P=0.003)are risk factors for failed smoking cessation.There are 76 patients smoking again in current smokers,most due to lack of self-control(76.3%).Compared to the elderly group,there is a higher proportion of smoking again due to the need of daily communication and work in the young group.Conclusions We still need to raise the awareness of smoking cessation for smoking patients with CAD.Following factors should be focused for tobacco control in CAD patients:younger age,lower cuItural level,not treated with PCI or CABG,patients with smoking family members.higher body mass index and higher total family income.
