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.

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.

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.

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 investigate the character of real-time gray-scale contrast-enhanced ultrasonography (CEUS) and its clinical value in diagnosing hepatic focal lesion. Methods One hundred and three patients with 142 focal hepatic lesions were examined by CEUS after an intravenous administration of the contrast agent, then the characters of the images were analyzed. Results The initial contrast-enhanced signal patterns were classified into 5 modes, peak contrast-enhanced signal patterns into 4 modes, and contrast agent perfusion patterns into 7 modes. Different lesions had different characters of contrast-enhanced phases. The accuracy rate of the CEUS in diagnosing focal hepatic lesion was 93.0%. which was significantly higher than that of conventional ultrasound and contrast-enhanced CT (X2=47.430, P<0.05). Conclusions The characteristic initial contrast-enhanced pattern and contrast agent perfusion pattern are helpful in the differential diagnosis of hepatic focal lesion, while peak contrast-enhanced signal pattern is relatively unreliable. Compared with conventional ultrasound and contrast-enhanced CT, CEUS can dramatically improve the accuracy of qualitative diagnosis of hepatic focal lesion.

Objective To investigate the litholytic effect of stirring by plastic stem inside biliary tract in large common bile duct (CBD) stone. Methods Forty-five patients with large CBD stones were included in this study (8 with the distal bile duct stricture and 5 with too-small Vater's papilla).Plastic stent of 8.5Fr was inserted into the CBD under the guidance of guide wire in all the 45 patients. Results In 10 of the 45 patients, ERCP showed that there was no stone in CBD 3 months later after stent placement. In 22 cases, repeated ERCP revealed that the stone had become smaller to the extent of more than a half or became stone fragments that were easily extracted by baskets or balloon dilation. Thirteen patients continued to have large stone at the second time ERCP treatment, and a new stent was replaced and follow-up performed by B mode ultrasonography of abdominal region per month. Further endoscopic treatment was performed immediately when the stone became small enough. The percentage of 95.6% (43/45) of large CBD stone were eventually cleared after endoscopic treatment for an average of 2.4 times. There were no severe complications related to ERCP or stent placement. Conclusion Placement of plastic biliary stent is a convenient and effective measure for the treatment of large CBD stones. It is especially appropriate for aged patients of CBD stone of high risk.
