Xuzhou Cancer Hospital explored a development and reform of the hospital in the PPP framework,while adhering to the principles of Public nature as before,staff status as before,and government supervision as before. The reform features proactive attempts in operation and management,personnel management,and remuneration system,in an effort to build an operation system featuring board governance,total cost accounting,and dynamic total salary management in its reform toward building an innovative mixed ownership.

BACKGROUND:Adenovirus, expressing within a limited period, can limit the expression time and amount of target genes that is not conducive to ongoing experiments. Here, we select adenovirus as vectors for genetic recombination with tumor necrosis factor (TNF)-related apoptosis-inducing ligand (Trail) gene fragment.
OBJECTIVE:To explore the construction of recombinant lentiviral vector carrying Trail in rats
METHODS:The Trail gene was obtained:according to GenBank in rat Trail gene sequence (NM_145681.1), we designed the gene specific primers of Trail-Age I-F and Trail-AgeI-R, and used AgeI as enzyme cutting site. PCR was applied to amplify Trail gene from rat cDNA Library and construct recombinant plasmids after cutting Trail gene to be cloned into expression vector GV218 by AgeI. Recombinant plasmids were transfected into 293T cells by Lipofeetamine2000 encapsulated recombinant plasmid and auxiliary packaging carrier. The Trail protein of lentiviral plasmids was expressed. Fol owing virus col ection, we identified virus titer and extracted protein from cells to detect Trail expression by western blot assay.
RESULTS AND CONCLUSION:Screened positive Escherichia coli DH5a competent cells were sequenced with 861 bp, which was consistent with Trail nucleotide sequence in GenBank. After transfection 2 days, virus liquid was col ected and confirmed as recombinant plasmid including Trail gene by PCR and Trail proteins expressed in 293T cells by western blot assay. Hole dilution method and real-time fluorescent quantitative PCR determination showed that the virus titer was 2×109 TU/mL. In this study, recombinant lentiviral vector carrying Trail is successful y constructed by homologous recombination in Escherichia coli.

Traditional Chinese medicine Polygoni Multiflori Radix is dried roots of Polygonaceae Polygortum multiflorum Thunb. Its clinical application records were first discovered in literatures of the Tang dynasty. The origins, efficacy, toxicity, processing and taboos of Polygoni Multiflori Radix have been discussed in many ancient herb literatures. In recent years, with the increase in the public awareness in health, Polygoni Multiflori Radix admits preparations have been more widely applied in the treatment and prevention of diseases. However, there have been more and more reports about Polygoni Multiflori Radix induced liver injury, the safety of Polygoni Multiflori Radix has increasingly attracted attention of the society. In this paper, the authors summarized and analyzed the toxicity and medication risk factors of Polygoni Multiflori Radix recorded in ancient herb literatures, and proposed that more attention shall be given to the effect of the planting and processing methods on the components and toxicity of Polygoni Multiflori Radix in safety studies, which provides clues for the further studies.

The renal toxicity and mutagenicity of aristolochic acid (AA) as well as its carcinogenicity on upper urinary tract transitional epithelial cells have been widely known. Since 2003, drug regulatory departments have successively cancelled the quality standards for AA-containing medicines such as Aristolochiae Radix, Aristolochiae Manshuriensis Caulis and Aristolchiae Fangchi Radix, and adopted measures for strengthening regulation and revising package insert or quality standards for other AA-containing medicines, including Aristolochia Cinnabarina Radix, Aristolochiae Fructus, Aristolochiae Mollissimae Herba, in order to control its safety risk. In recent years, domestic and foreign studies on AA have mainly involved action mechanism and clinical performance of AA toxicity, early-stage diagnosis and treatment method. In this paper, authors gave a brief summary and evaluation on risk factors for using AA-containing medicines, and offered measures and suggestions for preventing and controlling AA toxicity.

Objective To investigate the mechanism of preventing islet β-cell apoptosis in NOD mice with pioglitazone.Methods Female NOD mice at 4 weeks of age were divided into pioglitazone group ( n =21,0.02％pioglitazone was added into the feed ) and control group ( n =21,fed with regular diet).The accumulative incidence of diabetes was followed-up to 52 weeks of age in each group of NOD mice.Pancreas was removed from NOD mice at 12 weeks of age in each group ( n =15 ) to score severity of insulitis by routine H-E staining.The apoptotic β-cells in islets were observed with double-labeling technique of TUNEL in situ combined with standard sensitive avidin-biotin complex (sABC) immunohistochemical method.The spleens were taken for cell culture; IL-4 and IFN-γ levels in sera and supernatants of cultured splenocyte,the activity of PPARγ and NF-κB nuclear proteins in cultured splenocyte were measured by ELISA.Results (1)At 30 and 52 weeks of age,the respective incidences of diabetes were 57.1％ and 76.2％ in pioglitazone group,and 76.2％ and 90.5％ in control group ( all P＞0.05 ).At 15 weeks of age,the incidence became 4.8％ in pioglitazone group,and 33.3 ％ in control group ( P =0.045 ).( 2 ) At 12 weeks of age,the percentages of non infiltrated islet and peri-insulitis islet in pioglitazone group were higher than those in control group ( 14.73％ vs 5.69％,P＜0.01 ; and 26.02％ vs 15.72％,P＜0.01 ),and that of intraislet insulitis was lower than that in control group ( 59.25％ vs 78.59％,P＜0.01 ).The percentage of apoptotic β-cell in pioglitazone group was lower than that in control group( 6.17％ ±3.62％ vs 10.62％ ±4.43％,P=0.008 ).(3) In sera,IFN-γ level in pioglitazone group was lower than that in control group [( 561.05±78.61 ) vs ( 666.43 ± 28.42 ) pg/ml,P =0.045].In cultured splenocyte supernatant,the level of IFN-γ in pioglitazone group was lower than that in control group[(605.84+65.60) vs (692.20+44.98) pg/ml,P=0.041].(4) In cultured splenocyte,PPARγ nuclear protein activity in pioglitazone group was higher than that in control group ( 0.06 ± 0.01 vs 0.03 ± 0.01,P =0.013 ),and NF-κB nuclear protein activity was lower than that in control group ( 0.03 ± 0.01 vs 0.08± 0.01,P =0.001 ).Conclusions Pioglitazone activates PPARγ nuclear protein,inhibits activity of NF-κB nuclear protein,downregulates IFN-γ,diminishes differeutiation of Th cells to Th1,and subsequently prevents insulitis and β-cell apoptosis in NOD mice.
