?Objective:To study the influence of composite Danshen droplet pills on hemorheology in peripheral blood of patients with oral lichen planus (OLP).Methods:46 patients with OLP were treated by composite Danshen droplet pills for 8 weeks (oral administration,3 times/day,10 granules/time).The venous blood was taken and the hemorheology was studied with a LBY N6A hemorheology test machine before and after the treatment.Results:Effective results were observed in 33 patient and obvious effective results in 5,while no treating effect was found in 8 after treatment.Whole blood viscosity,blood plasm viscosity,erythrocyte aggregation indexs,thrombocyte aggregation rate,fibrinogen and ESR of the OLP patients were decreased ( P 0.05).Conclusion:The composite Danshen droplet pills may improve the hemorheology of OLP patients.

Peking University Health Science Center has various characteristics of educational manage-ment practice such as clear three level management, diversified management training and strict quality control, and at the same time there exist many deficiencies, such as lack of the implementation of management regulations and the requirements caused by multi-level management and management quality having ups and downs be-cause of human factors and etc.. By introducing life cycle management into national continuing medical educa-tion project management, we make management run through the whole life cycle of national continuing medical education project, namely five aspects of management from reporting and publishing, planning and publicity, holding and supervision, graduation and certificates, as well as summary and feedback, which plays an impor-tant role in standardizing the national continuing medical education project and improving the quality of the project.

Stroke is an important public health problem both in China and worldwide.Stroke genetics research has made great progress in recent years, especially the genome-wide association study (GWAS) and the emergence of epigenetics, has brought a breakthrough in this field. They studied the pathogenesis of stroke from the genetic level and the environmental factor levels. Although there are still many problems to be solved, the prospect of stroke genetics is bright.

Objective To observe the clinical efficacy and safety of Chushi Huowei Decoction in treating inflammation of gastric relict of spleen-stomach damp heat type. Methods Totally 62 patients with inflammation of gastric relict were divided into treatment group and control group with random number table, 31 patients in each group. The control group was given hydrotalcite and the treatment group was treated by adding of Chushi Huowei Decoction. After eight-week treatment, the clinical efficacy, gastric mucosal lesions efficacy, and gastric mucosal pathology efficacy of the two groups were compared. Results Eight-weeks later, traditional Chinese medicine symptom scores of both groups were obviously lower than those before treatment (P<0.01). And the decrease in the treatment group was more obvious than that in the control group (P<0.01). Curative effects of gastric mucosal lesions and pathologic condition in treatment group were better than those in the control group (P<0.05, P<0.01). Neither groups had any adverse reaction. Conclusion Chushi Huowei Decoction has reliable therapeutic effect and safety in treating inflammation of gastric relict of spleen-stomach damp heat type.

Background Lowing intraocular pressure (IOP) is the only effective treating method in glaucoma.Making sure the change of optic disc parameters and retinal nerve fiber layer thickness(RNFLT) in primary open-angle glaucoma (POAG) patients after IOP reduced can provide objective evidence for evaluating the effect of lowing-IOP on the function of optic nerve.Objective The present study was to evaluate the change of optic disc parameters and RNFLT in POAG patients after trabeculectomy,and analyze the affecting factors of image parameters.Methods A serial case-observational study was adapted.Forty eyes of 39 patients with POAG underwent trabeculectomy were recruited in the study.IOP was examined and perimetry was performed before operation and 2 weeks,1 month,3 months,6 months and 1 year after surgery.Optical parameters and RNFLT were measured using Heidelberg retina tomography (HRT) and optical coherence tomography (OCT) in above-mentioned time points.The correlations between lowing-IOP range or disease severity and optical disc parameters or mean RNFLT (mRNFLT) were analyzed by Pearson linear correlation.Results Mean IOP of the 40 eyes was (32.77±8.64) mmHg before operation and (12.45 ±3.65) mmHg,(13.05±3.90) mmHg,(13.42± 3.33) mmHg,(14.22± 2.60) mmHg and (14.74±2.46)mmHg 2 weeks,1 month,3 months,6 months and 1 year after operation,with a significant difference among various time points (F=13.73,P =0.00).However,no significant difference was seen in the mean defect of perimetry among the different time points (F=1.02,P=0.41).The cup area (CA),cup/disc area ratio (C/DAR),cup volume (CV),mean cup depth (MCD),cup shape measurement (CSM),horizontal C/D,vertical C/D,rim area (RA),rim/disc area ratio (R/DAR),height variation contour (HVC),rim volume (RV),mRNFLT,RNFL cross sectional area (RNFLA) were gradually improved after operation in comparison with before operation.One year after operation,RV,CSM,mRNFLT,RNFLA were still increased,but vertical C/D was reduced after operation than that of before (P＜0.05).No significant differences were found in the whole mRNFLT and superior quadrant mRNFLT,inferior quadrant mRNFLT,nasal quadrant mRNFLT and temporal quadrant mRNFLT among before and after operation (F=1.63,P=0.16; F=0.51,P=0.77; F=1.44,P=0.20;F=1.02,P=0.32; F=1.31,P=0.30).Positive correlations were found between lowing-IOP range and the improvement of RV,CSM,vertical C/D (r =0.45,P =0.02; r=0.41,P=0.04; r=0.58,P=0.00),and negative correlations were seen between absolute value of MD and the improvement of RV,CSM 1 year after operation (r=-0.43,P=0.03; r=-0.62,P=0.00).Conclusions Reduction of IOP after trabeculectomy results in the reversal of optic disc parameters.The improvement of the optic disc parameters may be a protective factor for progression of glaucomatous optical nerve damage.

Objective To study the effects of ?2-adrenergic receptor gene Arg16Gly polymorphism on blood lipid and apolipoprotein ratio and its role in blood lipid and apolipoprotein ratio mediated by high carbohydrate/low fat (HC/LF) diet in healthy young persons.Methods Fifty-six healthy young volunteers had regular diet for 7 d followed by HC/LF diet for 6 d.Twelve-hour fasting venous blood samples were collected on days 1,8 and 14 to measure blood lipid and apolipoprotein (apo) AI and B100 levels,and to calculate ratios of TG/HDL-C,log (TG/HDL-C),TC/HDL-C,LDL-C/HDL-C and apoAI/apoB100.DNA was isolated from genome.Arg16Gly polymorphism was analyzed by PCR-RFLP.Results No significant difference was found in the baseline lipid and apolipoprotein ratio in subjects with AA genotype and G carriers before and after regular or HC/LF diet.The ratios of TG/HDL-C (P=0.017),log (TG/HDL-C) (P=0.031),and apoAI/apoB100 (P=0.006) were significantly higher,while those of TC/HDL-C (P=0.001) and LDL-C/HDL-C (P

Objective To evaluate the perioperative management of blood pressure in patients with bilateral carotid artery severe stenosis underwent staging carotid endarterectomy (CEA).Methods This retrospective study included 31 patients with bilateral carotid stenosis who underwent bilateral revascularizations in our department from April 2012 to November 2015.Patients were recorded with general information,and the changes of blood pressure in preoperative,intraoperative and postoperative were observed,respectively.Regulation and control of blood pressure were performed according to individual patient's condition.Results Thirty one patients underwent a total of 62 consecutive procedures successfully.Postoperative symptoms disappeared or significantly reduced.Twenty three cases (74.2％) had high perfusion symptoms in the ipsilateral CEA,and 5 cases (16.1％) with high perfusion syndrome in the contralateral surgery.Patients were improved after strict control of blood pressure and dehydration reduced intracranial pressure.The high peffusion symptoms in patients were significantly improved or disappeared after 1 week.Doppler ultrasound was used to evaluate the carotid artery before discharge.Conclusions For patients with bilateral carotid stenosis,staging purposes CEA is safe and effective.However,perioperative blood pressure management is very important.Individual control of blood pressure can significantly reduce the risk of postoperative high perfusion and cerebral infarction.Blood pressure control is recommended after 1 week in about 85％ of preoperative blood pressure.
