This study was aimed to improve the drug activity of three kinds of isoflavones from Chickpeas.Biochanin A,formononetin and genistein were used as raw materials.Acetone was used as solvent.Potassium carbonate was used as catalyst.The etherification reaction was with 1,3-dibromopropane,1-bromopropane and 3-bromopropene.The results showed that 9 isoflavone ramifications were synthesized.This method was simple,easy to control with high yield.It was concluded that the product structure was confirmed by 1H-NMR,13C-NMR and ESI-MS analysis.It laid a foundation for the structural study basis in the further research of its drug activity.

Purpose To evaluate the clinical and pathological features of extramammary Paget’ s disease ( EMPD) and to investigate the related prognostic factors. Methods The clinical and pathological data of 30 patients with EMPD were reviewed retrospectively. The HE slides in the file were rechecked. Immunohistochemical stains were performed on archival paraffin-embedded sections with En-Vision method in 20 cases. Follow-up data were recorded. The relationship between the clinicopathological parameters and prognosis was statistically analyzed. Results Among the 30 patients, there were 26 males and 4 females, aged from 53 to 88 years with median age 70. Macroscopically, typical presentations of EMPD were eczematoid lesions. Microscopically, Paget’s cells were distributed sin-gly or in groups ( as glandular or nests patterns) within the epidermis. Immunohistochemical stains showed that Paget’ s cells were pos-itive for CK7, and negative for CK5/6 and p63. Follow-up data were available in 23 cases, 8 cases recurred resection, among them, 6 patients had positive resected margin and 4 died. The recurrent rate and mortality between the groups of dermal invasion and no der-mal invasion (P<0. 01 and P<0. 05), the groups of lymphatic metastasis and no lymphatic metastasis (P<0. 01), and the groups of positive and negative resected margin (P<0. 01 and P<0. 05) were statistically different. There were no statistically different with age and extent of lesion (P>0. 05). Conclusions CK7 is a sensitive and specific marker of Paget’s cells. Dermal invasion, lymphatic metastasis and positive resected margin are poor prognostic factors in EMPD.

To observe the effects of paeoniflorin and total flavones extracted from Qixue Bingzhi Recipe on proliferation of vascular smooth muscle cells (VSMCs) cultured in endothelial cell conditioned medium (EC-CM) induced by oxidized low-density lipoprotein (ox-LDL) and the expressions of platelet-derived growth factor and its receptor genes.

Objective To explore the influencing factors of degenerative lumbar spondylolisthesis (DLS).Methods Sixty-one DLS patients (DLS group) were enrolled in this study.The control group was formed by 61 patients with same gender and age matched.The lesion position was L4 in two groups.The correlation of intervertebral joint angle,degeneration degree,lumbosacral angle and lumbar spondylolisthesis were analyzed.Results The intervertebral joint and sagittal angle in DLS group was less than that in control group[(37.11 ± 7.52)° vs.(42.44 ± 7.61)°] (P ＜ 0.01).The lumbosacral angle between two groups had no significant difference (P ＞ 0.05).The degeneration degree between two groups had significant difference (P ＜ 0.01).Conclusion Intervertebral joint and sagittal angle and intervertebral joint degeneration degree have important roles in DLS.

Total 52 patients with breast lesions underwent dynamic contrast-enhanced breast MRI; and the breast vascularization was scored on the MRI vascular maps with a range of 0 to 3. The mean number of vessels per ipsilateral breast in malignant cases was higher than that of benign cases (3.8±2.0 vs. 1.3± 1.0; P=0.000). When the breast vascularity score 0-1 was defined as benign and 2-3 was defined as malignant, the sensitivity and specificity was 79% and 83%, respectively. Results indicate that dynamic contrast-enhanced breast MRI is of value in diagnosis of malignant breast lesions.

Objective: To summarize the clinical characteristics and therapeutic experience of optic gliomas. Methods: The clinical data of 7 patients of our department in the past 3 years were analyzed. Results: In this series of optic glioma patients, the average age was 18.7 years, the ratio of men to women was 4∶3,and 100% of the tumors were sub-totally removed. Diabetes inspidus was the most comman postoperative complication. Conclusion: The optic glioma is benign intracranial tumor with good prognosis. The key point of treatment is surgical resection combined with proper postoperative radiotherapy.

Objective To identify objective methods for medical service performance evaluation,and means to improve the efficiency of medical services.Methods By means of collection of medical records from 10 tertiary hospitals in Yunnan in 2012,and Diagnosis-related groups of Beijing version(BJDRGs)as a risk-adjustment tool,medical service performance was made to such hospitals.Results The capacity,efficiency and medical safety of hospital of the hospitals were subject to a comprehensive evaluation of their medical service capabilities.In terms of discharged inpatients and total weight,hospital A were found to be the highest(77 458 cases,104 227.5 respectively),and hospital I the lowest(25 450 cases,38 162.28)among these hospitals in 2012; compared with other hospitals,DRG groups of hospitals A,b and D were found higher,while the case mix index(CMI)of hospitals e and I were higher.The expenditure index of hospital C is the lowest(0.9359,0.8514); the mortality in cases of low risk of hospitals B,c and D were the lowest,while hospital F was the highest.Conclusion DRGs as a risk adjustment tool,can significantly improve the reliability,science and continuity of medical service performance evaluation,providing reliable basic data for hospitals accreditation in Yunnan.

Objective To analyze the differentially expressed genes in esophageal squamons cell carcinoma (ESCC), para-cancerous tissue (PCT) and normal esophagus tissue (NET) using oligomicroarray and to identify the target genes related to the development and progression of esophageal carcinoma. Methods The total RNAs isolated from ESCC, PCT or NET using one step Trizol method were purified and reversely transcribed into cRNAs. The cRNAs were then fluorescence labeled and hybridized with Agilent oligomicroarray (21 074 probes). The fluorescence intensity features were detected by Agilent scanner and quantified by feature extraction software. The selected candidate genes were confirmed by real time real time fluorescent quantitative RT-PCR immunohistochemistry andWestern blotting.Results ① The oligomicroarray demonstrated that there were 38 up-regulated genes and 61 down-regulated genes. ② The real time fluorescent quantitative RT-PCR revealed that five genes (CTHRC1, INHBA, SPP1 ,LUM, HRK)were more differentially expressed in up-regulated genes. Of which, CTHRC1 displayed more disparity.③ Immunohistochemistry examination showed that the higher expression of CTHRC1 (56.5 %, 26/46) was observed in ESCC. There was significantly difference in expression of CTHRC1 between patients with or without lymph node metastasis (P<0.05). ④ CTHRC1 protein was expressed in both TE-13 and Eca-109 cell lines. Conclusion CTHRC1 is probably one of the most significant biomolecules in ESCC.

The introduction of highly active antiretroviral therapy (HAART) has greatly changed the pattern and natural history of ocular diseases of HIV-infected patients, resulting from the immune recovery and reduction of opportunistic infections. However, ophthalmic complica-tion continues to be concern in AIDS even in the HAART era, especially in developing areas, where absolute majority of HIV-positive patients live. Lack of test facilities and experience, poor conditions of hygiene, different microbiological environment, absence of effective treatment etc., characterize the ophthalmic manifestation of HIV-infected patients in developing countries from that in developed regions and thus pose a great challenge to the ophthalmic treatment in developing area. Not only varied from region to region, ocular complications are distinctive between adults and children. At the same time, the side effects due to the application of HAART pose their own risks of ocular complication and should, therefore, be given more research attention.
