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.

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 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

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.

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.

Sixty lumbar intervertebral disc herniation (LDH) cases were treated with electroacupuncture on such major points as Jiaji ( Ex-B 2) in L4, L5, and S1 and Huantiao (GB 30) as well as adjunctive corresponding points in the affected area plus short-lever micro-adjustment manipulation. Another 60 cases in the control group were treated with tra-ction. After three treatment courses, the former got the effective rate of 93.3%, while the latter only got 77.8%. The two groups have a statistical difference in therapeutic effect (P＜0.05).

Objective To analyze the serum level of 25-hydroxy vitamin D [25-(OH) D] in pregnant women in Nanjing and its relationship with age,gestational week,pre-pregnancy body mass index (BMI) and season,so as to provide some guidance on clinical application of vitamin D measurement and supplementation.Methods 880 pregnant women (in 21-36 gestational weeks) regularly visiting antenatal clinic in Obstetrics and Gynecology Hospital Affiliated to Nanjing Medical University were selected from January to December 2015.Their serum 25-(OH)D concentrations were measured by enzyme-linked immunosorbent assay (ELISA).Results The mean serum 25-(OH) D concentration in these pregnant women was (42.03 ± 19.22) nmol/L and sufficient in only 42 (4.77％).Vitamin D levels showed seasonal variation (P =0.0164),with the levels in summer [(44.61 ±23.57) nmol/L] and autumn [(43.43 ± 19.31) nmol/L] being higher than spring [(39.68 ± 16.91) nmol/L] and winter [(39.65 ± 13.36) nmol/L].There was no statistically significant difference in serum vitamin D level among different gestational weeks (P =0.929 4).There was statistically significant difference in serum vitamin D level among different age groups (P =0.038 3).Vitamin D level was not associated with pre-pregnancy BMI.Conclusions Vitamin D deficiency is highly prevalent among pregnant women in Nanjing.We suggest vitamin D testing be carried out more actively.

Purpose:To evaluate the effect of continuous intraperitoneal washing chemotherapy in treating the abdominal cavity tumor of nude mice with human ovarian epithelial cancer.Methods:The abdominal cavity tumor of nude mice models was established with human ovarian serous epithelial cancer cell line SKOV 3. 20 experimental nude mice were divided into 3 groups: the common treatment group(7 mice),the continuous washing intraperitoneal chemotherapy group(7 mice) and the control group(6 mice).All the mice were killed after two courses of treatment and the weight and volume of the cavity tumor were examined. The cell cycle expresstion rate of C erbB2 and Fas of abdominal neoplasms tissues in washing liquid were detected with FCM. Results:In the intraperitoneal washing group,the nude mice's FBW/IBW was 0.886. The volume of the cavity tumor is obviously smaller than the routine group. Significant difference in tumor growth inhibition rate was found between the routine group and the washing group.In the washing liquid, G 1 and S phase ratios were markedly lower ( P 0.05); C erbB2 rates were 66%、59% and 42% in control、common and washing group respectively, which was significant different between all groups ( P
