Objective:To construct the plasmid containing short hairpin RNA(shRNA)of survivin and modify human bladder transitional cell carcinoma(BTCC)T24 cell line with it to evaluate its inhibition on tumor growth and proliferation and further discuss its functions in T24 cells.Methods:Survivin specific oligonucleotides were designed and synthesized.These oligonucleotides were annealed to form double strand DNA fragment and this fragment was inserted into plasimid PTZU6+1 to generate the plasimid pshRNA-survivin2.Then T24 cells were inoculated into the right-back legs of BALB/c nude mice to establish bladder cancer model.Through plasimid PTZU6+1,T24/survivin-siRNA expressing survivin was successfully constructed to study the effects of survivin-siRNA on BTCC growth and proliferation.Microscope was used to observe the morphological changes.Histological examination was under HE staining.Survivin was detected by SABC to evaluate the expression of survivin after the treatment of survivin-siRNA through PTZU6+1.Results:The expression of survivin in transfected T24 cells in vivo was markedly depressed as compared with control groups(P

That provincial hospital hosting the local hospital is an important measure to deepening the reform of medical and health system.Advanced hospital management mechanism and excellent technical experts were gradually introduced into the local hospital to establish South Hubei healthcare alliance,and form province-city-county healthcare alliance.In this way,high quality management,manpower and technology resource sink,overall medical technology level achieves good breakthrough.This promotes the rapid development of healthcare alliance member hospitals in the region.

Rheumatism of TCM(Traditional Chinese Medicine) is a kind of clinical frequent,common-see and refractory disease,which owns complex pathogenesis and pathogenic factors,with marginal and multi-disciplinary manifestations.The inconsistency in synopsis results in some di culties in research and impairs the development of clinical treatment.Therefore,it is a utmost important theme before us that how and by which ways to perform researches,also an important premise for normalization research on this disease.We try to explore the thinking and method of scienti c research of rheumatic disease from both basic and clinical aspects in this paper.

After chemotherapy, the healthy qi of acute leukemia (AL) patients was severly demaged, remnant toxin with internal amassment, qi and blood deficiency, blood stasis, vertigo with syndrome of stagnation and blockade of phlegm-damp. The clinical symptoms with cold-heat intermingled together which are complicated and changable were quite similar to those of Jueyin disease. Therefore, this paper tried to explore the differentiation and treatment of AL after chemotherapy from Jueyin. It was concluded that the treatment of AL after chemotherapy should be treated with cold and heat method, attacking and supplementing together, with nourishing the liver as the main part. At the same time, it was importance to protect healthy qi. Combined with the basic pathogenesis of AL, it was proposed that Danggui-Sini Decoction was suitable for the treatment of AL after chemotherapy. All in all, the paper explored the differentiation and treatment of AL after chemotherapy from Jueyin in order to use more Chinese medicine therapy in the field of AL treatment.

AIM To develop the quality control methods for Yixuning Tablet (Fructus Lycii,Radix Polygoni Multiflori Preparata,Radix Codonopsis,etc.) METHODS RP-HPLC was performed for the assay of 2,3,5,4′-tetrahydroxy-stilbene-2-O-?-D-glycoside.TLC was used to identify Fructus Lycii,Radix Polygoni Multiflori,and Radix Angelicae Sinensis. RESULTS The good linearity was within the range of 20-180 ?g?mL -1 ( r = 0.999 9 ).The average recovery was 99.0 % ( RSD was 2.8 T《B》 % ).TLC methods were special. CONCLUSION The method is convenient,accurate and sensitive.and suitable for the quality control of the preparation.

The ongoing health reform features direct hosting of county-level hospitals by provincial level hospitals as an important means and effective attempt to improve comprehensive service capacity of the former.This paper introduces the“Hanchuan Model”,in which Hubei People’s Hospital has hosted Hanchuan city People’s Hospital,and analyzed the operation performance and hurdles found.Based on such studies,the authors recommend on the vertical integration of medical resources by means of hosting, and comprehensive reforms of county public hospitals.

Cell senescence is an important anti-cancer mechanism and may contribute to cancer therapeutic outcome. The present study observed the effects of Tenglong Buzhong Decoction (TLBZD), a Chinese herbal formula, on senescence in human colon carcinoma LS-174-T cells.

Objective To investigate the relationship between the levels of circulating pregnancy-associated plasma protein A(PAPP-A,a novel marker of atherosclerotic plaque activity) and myocardial perfusion before or after percutaneous coronary intervention(PCI) in patients with non-ST elevation acute coronary syndrome(NSTEACS).Methods Forty-four patients with high-risk NSTEACS were examined for serum PAPP-A levels,cardiac troponin T and the brachial artery flow-mediated vasodilation(FMD) before PCI.The angiographic data was analyzed before and after PCI in terms of TIMI myocardial perfusion grade(TMPG) in the area of culprit vessels.Results Before PCI,twenty patients with TMPG 1-2 had higher PAPP-A levels(30.41?21.33 mIu/L vs.23.55?18.61 mIu/L,P=0.036) and lower FMD(2.95%?1.71% vs.3.54%?1.58%,P=0.027) companed with the patients with TMPG 2-3.After PCI,twelve patients with TMPG 1-2 had higher PAPP-A levels(35.64?20.58 mIu/L vs.21.87?19.30 mIu/L,P=0.009) and lower FMD(2.26%?1.83% vs.3.95%?1.43%,P=0.018) than those with TMPG 2-3.Conclusion The PAPP-A level and the degree of endothelial dysfunction play roles in myocardial perfusion in patients with high-risk NSTEACS.

Objective: To observe the effects of Tenglong Buzhong Decoction (TLBZD), a compound traditional Chinese herbal medicine, on proliferation and apoptosis of colon carcinoma cell line LS174T in vitro. Methods: Human colon carcinoma cell line LS174T and human colon epithelial cell line CRL-1790 were treated with different doses of TLBZD. Cell proliferation was detected with cell counting kit-8 (CCK-8) assay and clone formation assay. Cell cycle and apoptosis were detected by flow cytometry, and caspase-3, -8 and -9 activities in LS174T cells were detected by colorimetric assay. Results: TLBZD had no obvious cytotoxicity in normal CRL-1790 cells. After 72-hour treatment of 1 mg/mL TLBZD, or 48- and 72-hour of 2 mg/mL TLBZD, or 24-, 48- and 72-hour of 5-20 mg/mL TLBZD, proliferation of LS174T cells was significantly inhibited. Clone formation of LS174T cells was significantly inhibited by 1 to 20 mg/mL TLBZD treatment. TLBZD at doses of 5 to 20 mg/mL also induced apoptosis and cell cycle arrest at G(0)/G(1) phase in LS174T cells. In addition, caspase-3, -8 and -9 activities were significantly elevated after 5 to 20 mg/mL TLBZD treatment. Conclusion: TLBZD can inhibit cell proliferation, arrest cell cycle at G(0)/G(1) phase, and induce apoptosis in LS174T cells, which may be related to activating of caspase-3, -8 and -9.

Objective To study the method for determination of nipacide PX and triclosan in disinfectant by high performance liquid chromatography. Methods High performance liquid chromatography, based on the mobile phase (CH3CN:H2O=60:40, pH=3.0) and diode array detector(DAD, ?= 280 nm), was chosed to determine nipacide PX and triclosan in disinfectant. Results The detection limit of nipacide PX was 2.48 ng and triclosan was 2.08 ng. The rate of recovery was 95.4%-103.3%,the relative standard deviations(RSD) was 0.6%-3.4%. Conclusion The method is simple, precise and suitable for the determination of nipacide PX and triclosan in disinfectant.
