Objective To explore the clinical effect of agar alginate combined impression preparation of a fLxed partial denture impressions.Methods 88 cases of patients with fixed partial dentures were divided into experimental group(group A) and control group(group B).Group A of 45 patients with 93 abutments,the legal system to take an impression of agar and alginate combined impression; group B of 43 patients with 80 base,the use of alginate impression preparation of an impression.Were observed with a magnifying glass impression of the type and number of records the number of abutments,impression defects.Results 63(67.8％) of group A were ideal,30(32.2％) had defects,33(41.2％) of group B were ideal,47(58.8％) had defects,there were significant differences(x2 =19.36,19.28,all P ＜ 0.05).At the cervical margin of bubbles,the gingival sulcus and shoulder were not clear,there was significant difference(x2 =10.46,11.25,all P ＜ 0.05).There were no significant difference in tear or defect of the neck at the edge of the two impression.Conclusion Agar and alginate impression of the legal systemcan take an impression of reduced defects,which is worthy of clinical application

Primary hypophysitis includes 3 subtypes:lymphocytic,granulomatous and xanthomatous hypophysitis. The primary hypophysitis has a low morbidity and the final diagnosis is mostly determined based on the pathological findings after operation.Now it is considered as an organ specific autoimmune disease.Its clinical manifestations and imaging features are similar to hypophyseal tumor,but the endocrine and pathologic features are different.Glucocortieoid pulse therapy and surgery are the two methods of treatment.

Objective To study the relationship between hyperhomocysteinemia and type 2 diabetes patients with cerebral infarction and its influencing factors.Methods Serum homocysteine levels were measured by high performance liquid chromatography (HPLC) in type 2 diabetes patients with cerebral infarction (DS group), type 2 diabetes patients without complications (DNC group) and normal control subjects. Plasma folate and VitB 12 concentrations were detected by radioimmune assay.Results The levels of homocysteine in DS group and DNC group were significantly higher than in normal control group (all P

ObjectiveTo evaluate the performance of diagnosis-related groups,Beijing version (BJ-DRGs) which were locally developed in Beijing.MethodA total of 1.3 million inpatient records from 149 hospitals in Beijing in 2008 were drawn from Beijing Public Information Center.Coefficient of variation (CV) was used to measure the performance of DRGs system.ResultsBJ-DRGs produced the best CV results for expenditure.ConclusionsUnder Beijing's medical information condition,BJ-DRGs produced good performance.

In this study, we aimed to investigate the regulatory effect of troglitazone (TGZ) on aromatase activity (AA) in human ovarian granulosa cells. The granulosa cells obtained from women who underwent in vito fertilization were treated with various concentrations of TGZ and/or retinoid X receptor ligand (RXR) LG100268 (LG), for 24h, and then cellular AA and the level of P450arom mRNA were determined. The treatment of the cells with TGZ for 24 h resulted in a dramatic inhibition of AA in a dose dependent manner. While the treatment with LG alone inhibited AA, the combined treatment with both TGZ and LG caused a much more reduction in AA. The changes in AA by TGZ and/or LG were associated with comparable changes in P450arom mRNA assessed by RT PCR. These results suggested that TGZ directly inhibited AA in human granulosa cells probably via nuclear receptor system which was composed of peroxisome proliferator activated receptor ?(PPAR?):RXR heterodimer.

Objective To evaluate the utility of three-dimensional digital subtraction angiography(3D-DSA) in the diagnosis of cerebral vascular diseases.Methods Seventy-one patients suspected and diagnosed with cerebral vascular diseases underwent conventional DSA and 3D-DSA. Three-dimensional (3-D) reconstructed images were obtained at a separate advantage 4.0 workstation after the rotational images were transferred. The available visualization techniques included maximum intensity projection (MIP), shaded surface display (SSD), and virtual angioscopy (VA). Results Sixty-four aneurysms were found in 44 cases. Nineteen cases were diagnosed as cerebral arteriovenous malformation (AVM) and 8 cases of cerebral ischemia were due to cerebral vascular stenosis (internal carotid artery in 6 cases and occlusion of anterior cerebral artery in 2 cases).Conclusions 3D-DSA is reliable, fast and safe for diagnosis of cerebral vascular diseases, especially involving intracanal areurysms AVM and vascular stenosis.

Objective To study the clinical evaluation of the effect of topical application of Periocline ointment in the adjuvant treatment of periodontitis.Methods100 patients with periodontitis as the research object in this study in Xi'an Jiaotong university school hospital from April 2015 to August 2016 were randomly divided into the control group and the experimental group, 50 cases in each group.The control group were treated with the conventional treatment, at this basis, the experimental group were given Periocline ointment topical application as the auxiliary treatment.Eight weeks after treatment, the clinical treatment and related indicators were compared in the two groups.ResultsThe bleeding index, probing depth and attachment level in the experimental group were significantly better than those in the control group (P<0.05).In the experimental group of 50 patients, the total effective number of cases in the treatment of 48 cases, The total effective rate in the experimental group was 94.0%, which was significantly higher than 88.0% in the control group (P<0.05).ConclusionIt can improve the effective rate that Periocline ointment was local applicated in the adjuvant treatment of periodontitis;it is worthy of clinical application.

Objective To investigate the imaging manifestations and clinical features of hepatic and renal angiomyolipoma. Meth-ods The clinical data and imaging findings of hepatic and renal angiomyolipoma in a 51-year-old woman was retrospectively ana-lyzed with literature review. Results CT scan showed a large polymorphous hypodense mass in the right lobe of liver. After contrast -enhanced CT scan, the mass was enhanced gradually from periphery to ceritre. Bilateral kidneys obviously enlarged and appeared as alveolate appearance mixed density with spotty and stripped fat structures. At contrast-enhanced scan, the normal structures of cor-tex and medulla were disappeared, the alveolate walls were enhanced obviously. The arteries and veins of bilateral kidneys were com-pressed and displaced. Conclusion The imaging features of liver and kidney are of certain characteristic compared with other benign and malignant masses,but the final diagnosis of it is still depending on pathology mostly.

Objective Beijing plans to run a DRGs-PPS pilot.The relative height of each DRG group produced by the price of charge categories.Because of serious distortions of medical services prices,DRGs'weight must be adjusted.Methods Dividing medical service into 5 major class-medical,nursing,technique,drugs and consumables,management,a conversion with currency were established to produce the cost.Results The weight of groups involve intervention from MDCF are drop.ConclusionThe weight regulated can optimize resources allocation and reflect the ture value of medical service.
