Objective To study the clinical characteristics and therapeutic effect of the combination of intensive immunosuppression therapy with umbilical cord blood infusion in severe aplastic anemia (SAA) patients with infections.Methods A retrospective analysis of bacterial spectrum and treatment effect was performed for infections occurred in 27 SAA-Ⅰ patients who received antithymocyte globulin (ATG),cyclophosphamide (Cy) and cyclosporine A (CsA) followed by umbilical cord blood infusion.Results The prevalence of infections in 27 SAA-Ⅰ patients was 48.1％,among which 70 ％ were infected with bacteria (mostly gram-negative bacilli) and 30 ％ with fungal infection.Upper respiratory tract was the most common site,followed by the blood and lungs.The primary infections occurred at the median time of 9.5 d (-2-10 d)after the immunosuppressive therapy,and the initial infections of ANC were ＜ 0.2 ×109/L.Conclusion Combination of intensive immunosuppression and umbilical cord blood infusion is proven effective in treating SAA-Ⅰ.As a result,infection rate is low and can be controlled with sensitive antibiotics.

Single nucleotide polymorphism( SNP) is a major source of genetic differences, and the number of SNP is extremely large. Consequently, a high-throughput, rapid and cost-effective technique is essential for SNP typing. Recently, a set of solutions aimed directly at the bottlenecks in SNP detection were put forward, which including direct PCR from human whole blood, adapter-ligation mediated allele-specific amplification, gene polymorphism detection in one tube, microplate array parallel gel electrophoresis and microchip electrophoresis. These methods have been successfully applied in pharmacogenomics, disease-related research, herbal medicine identification and quality control. The results showed that the advantages of the genotyping platforms are highly specific, sensitive, easy to operate and inexpensive with a good prospect of application. The principles and applications of the genotyping platforms in detail were described in this paper.

Objective To analyze hospitalization expenses and influential factors of elderly inpatients with medical insurance,and to provide scientific evidences for curbing hospitalization expenses and adjusting medical insurance policy.Methods Based on hospitalization data derived from Beijing town during 2007-2011 from 65082 elderly urban inpatients under medical insurance,descriptive analysis and multiple stepwise linear regression methods were used to analyze the hospitalization expense and its influential factors.Results The last 5 year witnessed rising hospitalization expense and average hospitalization expense per admission of elderly patients with medical insurance; among the components of hospitalization expense,cardiovascular/cerebrovascular/tumor/respiratory system diseases cause the heaviest medical burden; days of stay,hospital level,out-of-pocket proportion are the most important influential factors on their hospitalization expense per time.Conclusion The hospitalization expense of elderly patients with medical insurance keeps growing.Therefore,shorter days of stay,rational referral of patients to appropriate hospitals,adjusting out-of-pocket proportion would be effective measures of curbing hospitalization expense.

BACKGROUND:The quantity and function reduction of circulating endothelial progenitor cells(CEPCs)indicate that vascular endothelial repair capacity reduces in hypertension patients,but the impact of statins on the CEPCs is still not very clear.OBJECTIVE:To investigate the effects of atorvastatin calcium on endothelial cells and CEPCs in renovascular hypertensive rats.DESIGN,TIME AND SETTING:Randomized controlled animal experiment was performed in Chongqing Key Laboratory ofNeurology from June 2008 to Febmary 2009.MATERIALS:Totally 24 SD male rats of SPF grade,and atorvastatin calcium was produced by Lipitor,Pfizer Inc.with batch number of 65837003.METHODS:The renovascular hypertension was induced with 2-kindey and 1-clip method in 16 SD rats,which were then randomly divided into two groups:hypertensive group(n=8)and statins group(n=8).control group(n=8)underwent the same operation,without silver slip.At 4 weeks after model construction,statins group was treated with atorvastatin calcium MAIN OUTCOME MEASURES:At 4 and 12 weeks of the experiment.three groups of rats were measured blood pressure and blood lipids;at 12 weeks,the thoracic aortic endothelial cells continuity was investigated through hematoxylin-eosin stain;the quantity,proliferation,adhesion and migration capacity of CEPCs were determined.RESULTS:At 4 and 12 weeks of the experiment,there was no significant differences in the systolic pressure between statins RESULTS:At 4 and 12 weeks of the experiment,there was no significant differences in the systolic pressure between statins group group and model group,which were dramatically high than control group(P＞0.01):the blood lipids in the statins group was not changed.In the model group,rat aortic endothelial cells were greatly damaged;the injury of CEPCs was dramatically relieved in the model group.Compared with statins group and control group,the number of CEPCs was significantly decreased,the capacities of proliferation,adhesion and migration were also significantly reduced in the model group(P＜0.01);moreover,statins group was inferior to control group in terms of these capacities.with significant differences among three groups(P＜0.01).CONCLUSION:Renovascular hypertensive rats thoracic aortic endothelial calls are severely damaged,CEPCs decline in the humber and function;atorvastatin calcium can increase the number of CEPCs and improve the function of CEPCs.

To establish a simple and rapid method to genotype the human single nucleotide polymorphisms(SNPs). Methods:In the presence of the appropriate Cy5-ddNTPs and dNTPs,the primer was extended by one or more bases depending on the sequence at the polymorphic site. The microchip electrophoresis was used to detect the product of extension.The switching characteristics of the primer extension reaction was increased by introducing an artificially mismatched base into the third position from the 3'-terminus of the primers. Results:Three human SNPs were detected and the alleles were distinguished on the basis of size of the extended product. All samples were accurately assayed within 100 s in microchip electrophoresis. Conclusion:This technique offers a high-speed,easy and cheap method for genotyping SNPs.

Objective To evaluate the efficacy and safety of common therapy and individualized treatment in newly diagnosed patients with Helicobacter pylori (H.pylori) infection.Methods From March 2008 to February 2010,September 2013 to April 2014,January to October 2015,a total of 1 440 patients with H.pylori infection who received eradication therapy and with complete clinical data were retrospectively enrolled.Each was 350 cases in individualized treatment group,clarithromycin and bismuth containing quadruple therapy group and concomitant therapy group.A total of 100 cases were in standard triple therapy group,90 cases in sequential therapy group,and 200 cases in levofloxacin and bismuth-containing quadruple therapy group.The eradication rate of H.pylori,incidence of adverse events and compliance rate were compared in the six groups.Chi square test was performed for statistical analysis.Results The results of intention-to-treat analysis indicated that there was no statistically significant difference in H.pylori eradication rates among six groups (x2 =0.985,P=0.323).However,the results of modified intention-to-treat analysis showed that H.pylori eradication rate of individualized treatment group was the highest (92.5％ (282/305) and 93.3％ (278/298)),second was levofloxacin and bismuth-containing quadruple therapy group (90.3％ (167/185) and 91.6％ (164/179)),and the differences were statistically significant (x2 =11.285 and 13.981,both P＜0.01).There was statistically significant difference in indcidence of adverse events among the six groups (x2 =5.692,P=0.018),the incidence of adverse events in levofloxacin and bimuth-containing quadruple therapy group was lowest (16.2 ％ (30/185)),and second was individualized treatment group (21.0％ (64/305)).There was statistically significant difference in compliance rates among the six groups (x2 =4.712,P=0.023),the compliance rates of standard triple therapy group and sequential therapy group were highest (100％ (100/100) and 100％ (90/90)),and second was individualized treatment group (97.7％ (298/305)).Conclusions Both the levofloxacin and bimuth-containing quadruple therapy group and individualized treatment group can effectively eradicate H.pylori infection.The former may be safe and effective to patients unable to receive individualized therapy.
