Objective:To optimize the extraction process of the total flavonoids from Ephedrae Radix Et Rhizoma. Methods:The purification method of the total flavonoids from Ephedrae Radix Et Rhizoma was optimized with the yield and content of the total fla-vonoids as the indices. Based on the above research, the process parameters were optimized by an orthogonal test. Results:The opti-mum purification conditions were as follows:the volume fraction of ethanol was 50%, the stirring extraction time was 20 min, and the liquid-solid ratio was 8∶ 1(ml·g-1). Conclusion:The optimum purification technology is simple and reproducible, and suitable for the industrial production.

Objective:To optimize the extraction process for the total saponins from the root of Thladiantha dubia Bunge. Meth-ods:The extraction technology was optimized by orthogonal experiment with the dissolution content of total saponins as the index and the extraction times, extraction duration and ratio of solid to liquid as the influencing factors. Results:The optimum extraction condi-tions for the total saponins from the root of Thladiantha dubia Bunge were as follows:the reflux extraction was conducted twice(1. 5 h per time) with 70% ethanol as the solvent, and the ratio of solid to liquid was 1 ∶6. Conclusion:The optimum extraction technology is simple, reproducible and stable.

Objective To study the etiology,diagnosis and treatment of xanthogranulomatous cholecystitis (XGC).Methods Clinical data of 78 cases with xanthogranulomatous cholecystitis (confirmed by postoperative pathology) from January 1985 to December 2012 were reviewed retrospectively.Results All 78 cases underwent ultrasonography,50 cases did CT scan.Preoperative diagnosis included chronic calculous cholecystitis in 60 cases,gallbladder carcinoma with cholelithiasis in 8 cases,gallbladder space-occupying lesions in 10 cases.Among those 68 cases of tentative gallstone disease,67 cases were with gallbladder neck incarcerated stones.Surgery were performed in all 78 cases including cholecystectomy in 48 cases,partial cholecystectomy or subtotal resection in 13 eases,cholecystectomy with partial hepatic wedge resection in 12 cases.Intraoperatively 5 cases were misdiagnosed as the carcinoma of the gallbladder and underwent partial liver resection along with cholecystectomy.17 cases underwent choledocholithotomy.2 cases suffered from hepatic duct injury and received Roux-en-Y hepatojejunal anastomosis.Conclusions XGC is a special type of chronic cholecystitis,and accompanied by yellow granuloma formation.Preoperative diagnosis of XGC is often difficult,the definite diagnosis depends on intraoperative fiozen and postoperative paraffin pathology.

Objective To evaluate the vulnerability of carotid arteriosclerosis plaque by ultrasound real-time tissue elastography in patients with SSS-TOAST1 style cerebral infarction, and discussing the value of the technique in assessment of the clinical course after cerebral infarction. Methods There were 113 patients of SSS-TOAST1 style cerebral infarction who had carotid arteriosclerosis plaque and 48 patients of contrast group who had carotid arteriosclerosis plaque selected by ultrasound in Department of Ultrasound, Beijing Tiantan Hospital, Capital University of Medical Sciences. The results between two groups were compared. The cerebral infarction group was divided into two sub-groups according to the clinical course of patients after cerebral infarction, and the difference between them was compared. Results The size had no significant difference between cerebral infarction group and contrast group as well as between aggravated group and non-aggravated group (t=15.61, 10.77, 4.52, P<0.05). The real-time tissue elastography of carotid arteriosclerosis plaques were red-green in most patients of cerebral infarction group. The real-time tissue elastography of carotid arteriosclerosis plaques were green-blue in most patients of in control group. The value of elasticity of plaque, vessel wall and stiffness of carotid arteriosclerosis plaque between cerebral infarction group and control group had significant differences (t=15.61, 10.77, 4.52, P<0.05). The value of real-time tissue elastography between aggravated group and non-aggravated group had significant difference (t=6.39, 2.30, 3.80, P<0.05). Conclusion Real-time tissue elastography could evaluate the stiffness of carotid arteriosclerosis plaque, which was related with the vulnerability of carotid arteriosclerosis plaque. The values of elasticity of plaque, vessel wall and stiffness of carotid arteriosclerosis plaque in patients with SSS-TOAST1 style cerebral infarction were lower, and the vulnerability of carotid arteriosclerosis plaque was higher. Real-time tissue elastography had some worth in evaluating the clinical course of patients after cerebral infarction.
