Objective The microbiology specimen types were various and complex ,the system of main specimen types in micro-biological detection was established under the laboratory information system (LIS) for realizing the management target of quality control before microbiological analysis .Methods A total of 3304 submitted microbiological samples were collected from January 1 to 31 in 2015 .After setting the microbiological item application procedure of main specimen types in LIS ,1532 submitted microbio-logical specimens from June 20 to 24 were performed the statistics .The error rates of specimen types were compared before and af-ter setting .Then 1635 and 1340 submitted microbiological specimens were re-collected form July 9 to 13 and August 10 to 15 ;the change of error rates was continuously observed for comparing whether the statistical difference of error rates existing between be-fore and after setting .Results The error rate of submitted microbiological specimens before setting was 4 .6% (152/3304) ,which after setting was 1 .3% (20/1532)(χ2 =31 .224 ,P<0 .001) ,which during the continuous observation period maintained the lower level of 1 .04% (17/1635) ,χ2 =39 .658 ,P<0 .001) and 0 .9% (13/1340 ,χ2 =34 .673 ,P<0 .001) .Conclusion Re-setting the LIS reduces the error rate of microbiological specimen type ,effectively increase the working efficiency and reaches the quality control in-dex before microbiological analysis .

Vertebral artery hypoplasia is a congenital vessel variation. Its incidence is from 1. 9 to 26. 5% . In recent years, studies have shown that vertebral artery hypoplasia may be a potential risk factor for posterior circulation infarction, especialy when it coexists with other cerebrovascular risk factors. Vertebral artery hypoplasia may also cause regional hypoperfusion and complex neurovascular regulation, and it also has a certaln link with migralne.

With the development of functional genomics, high throughput analysis of genes’ function has been the mainstream of research, and exogenous gene's over expression via Agrobacterium-mediated transformation is the most commonly used method in gene functional analysis.The versatile plant expression vector cassette named pBHT-5 was constructed by the method of site-specific mutagenesis based on pBI121. First of all, the restriction enzyme SfiI recognition site in trfA gene (X00713) which was relevant to plasmid replication and stability was replaced without changing its amino acid composition. And then the SfiIA,SfiIB sites were added between promoter CaMV35s and terminator NOS. The versatile plant expression vector cassette can be directly used to construct plant expression vector containing the full-length genes cloned by Clontech SMARTTM technology, which will raise the efficiency of vector construction. The result will provide basis of new genes’ high throughput screening and functional analysis, then get the new genes functioning in plant osmotic stress resistance.

Two-dimensional electrophoresis(2-DE) is an important technique in proteomics research.The 2-DE system for proteome of Monascus ruber was established by comparing and analyzing the infection caused by different kinds of mediums,lysis buffer and the condition of rehydration.By cultivating the Monascus ruber with YES for 6 days,extracting total protein by TCA-acetone,lysis buffer with 8 mol/L urea,2 mol/L thiourea,4 % CHAPS,1 % DTT and 2 % Bio-lyte,an ideal 2-DE map with higher resolution and better legibility was obtained,which laid a foundation for the further studies on proteome of Monascus ruber.

Objective:To analyze the cause of the blood heat syndrome in psoriasis.Methods: Made the investigation form about information of psoriatic patients through DME method and reference both Chinese and foreign documents,analyzed main component of data by SAS software.Results: The first main component of blood heat syndrome in psoriasis are infection,drinking,dietetic problem,and emotion;the second main component is family history;the third main component is dampness;the forth main component is the allergy to the food;the fifth is outside irritation.Through the corresponding investigation we found that food include hot food,beef,sheep and sea food,emotion problem include over work and stress,dampness include work and living in humid place for long time,outside stimulus meant chemical stimulus.Conclusion: The main cause of the blood heat syndrome in psoriasis are infection,drinking,dietetic problem,and emotion,family history,humidity,allergy to the food and chemical stimulus in order.

Objective:To study the influence of Wnt5a gene silence on the proliferation,migration and invasion of lung squamous carcinoma cells.Methods:A recombinant plasmid pHI-siRNA~(Wnt5a-)was constructed and used to deliver small interference RNA (siRNA)targeting Wnt5a in SK-MES-1 cells;the transfected cells were screened to establish a stable transgenic cell line.MTT,cell cycle and Transwell assays were employed to evaluate the effect of Wnt5a gene silence on the proliferation,migration and invasion of lung squamous carcinoma cells.Results:Western blotting assay revealed that Wnt5a was lowly expressed in SK-MES-1~(Wnt5a-)(13.6%).The proliferation index(PI)of transgenic cell line was slightly lower than that of the control cell line([28.3?3.8]% vs[30.5?5.2]%). The migration and invasion capabilities of SK-MES-1~(Wnt5a-)cells were(47.3?9.2)% and(39.7?11.7)% of the control cells, respectively.Conclusion:Low Wnt5a expression can significantly inhibit the migration and invasion capabilities of SK-MES-1 cells, indicating that Wnt5a might be a potential target for gene therapy of lung squamous carcinoma.

Aim To research the protective effect and mechanisms of taurine on myocardial ischemia and reperfusion injury in rats. Methods Myocardial ischemia reperfusion models were established in SD rats. The effects of taurine on the size of myocardial infarction and the changes of activity of SOD , and the levels of MDA and NO in myocardium and plasma of rats with myocardial ischemia and reperfusion injury were observed. Results In rats with myocardial ischemia and reperfusion injury, the taurine could reduce the size of myocardial infarction (P

Background and objectives Proliferation of human vascular smooth muscle cells (VSMCs) induced by hyperinsulinemia is a very common clinical pathology. Extensive research has focused on PKC (Protein kinase C)-MAPK (mitogen-activated protein kinase)intracellular signal transduction and the phenotypic modulation accompanied by reorganization of intracellular F-actins in VSMCs.Methods DNA synthesis, signaling of ERK1/2 MAPKs, and changes in α-smooth muscle (SM) actin and F-actin were studied in hypertensive and normotensive human arterial VSMCs exposed to insulin and PMA with and without the PKC inhibitor, GF109203X.Results Differences among cell types in MAPK signaling, α-SM actin, and F-actin isoforms in VSMCs harvested from the arteries of patients with essential hypertension (EH) and normotension (NT) were identified in response to insulin treatment. Proliferation and activation of MAPK were more pronounced in EH VSMCs than in NEH VSMCs. Insulin exposure decreased expression of α-SM actin and was accompanied by rearrangement of intracellular F-actins in VSMCs, especially in the EH group. These effects were reversed by treatment with the PKC inhibitor. Conclusions Human mesenteric VSMCs of EH and NT patients differed in proliferation, MAPK signaling, and degree of changes in α-SM actin and F-actin isoforms immediately following insulin exposure in vitro.
