Objective To explore a separation and culture method of human adipose-derived stem cells(ADSCs) suitable for the clinical application .Methods The non-enzymatic method and the collagenase digestion method were adopted to isolate and culture the cells from the human adipose tissue in the individuals with liposuction .The characteristics of isolated mesenchymal stem cells were comparatively analyzed .Results The required time in the non-enzymatic method was one third of that in the collagenase di-gestion method and the cellular morphology ,reproductive capacity ,immunophenotype and differentiation potential of the isolated cells were consistent to those isolated by the collagenase digestion method .Conclusion The no-enzymatic method may isolate and culture ADSCs from the adipose tissue in the individual with liposuction ,which is a safety and reliable isolation and culture method of human adipose tissue-derived stem cells suitable for clinical application .

Objective To explore the change characteristics of physiological indexes between infants and children during living-donor liver transplantation and discuss methods of regulation and control.Method In this study,42 patients were selected and assigned into two groups according to age:infants group (＜1 year,n =25),and children group (1-16 years,n =17).The preoperative and peri-operative characteristics,intra-operative operation conditions,internal environment changes before and after re-perfusion,postoperative mechanical ventilation time,ICU time,hospital time,infection rate,additional surgery,complications and survival were analyzed.Result PELD (MELD) score,historical surgery rate and hematokrit were lower in children group than in infants group (P＜ 0.05).Serum creatinine and lactate concentrations increased significantly in children group as compared with infants group (P＜0.05).Intra-operative an-hepatic phase and cold ischemia time were shortened significantly (P ＜ 0.05),and incidence rate of re-perfusion syndrome was reduced in children group as compared with infants group (P＜0.05).As compared with pre-re-perfusion,blood lactate concentrations were significantly raised only in infants group and glucose concentrations significantly raised only in children group (P＜0.05).The blood levels of K + were decreased after reperfusion in both two groups,and those in infants group were lower than in children group (P＜ 0.05).Postoperative intensive care unit time was longer in children group than in infants group (P＜ 0.05),and there was no significant difference in survival rate between two groups.Conclusion There are many differences and change characteristics to physiological indexes between infants and children during the operation of living-donor liver transplantation.Timely management and regulation are critical for the success of surgery according to the differences.

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.

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.

A biomedical entity association evolution network was constructed by mining the implicit associations in PubMed-covered literature, which can help scientific researchers to form new scientific hypotheses, to analyze the topological features of associated network, to study the scientific literature-enriched knowledge structure, associa-tions, development rules, to introduce new visual angles and methods for literature-based knowledge discovery, and to improve the knowledge discovery efficiency.

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.

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.
