[ABSTRACT]OBJECTIVETo study the clinical effect of CO2 laser in the treatment of hypertrophic ventricular dysphonia.METHODSFrom December 2011 to December 2013, 40 patients with hypertrophic ventricular dysphonia were treated in our department. Conservative treatment had no valid for all of them. All the patients were examined with strobolaryngoscope and voice analysis (including fundamental frequency, jitter, shimmer and harmonic to noise). After general anesthesia, the hypertrophic ventricular cords were excised with CO2 laser under suspension laryngoscope.RESULTS The Hoarseness were better in all the patients after operation. The ventricular cord and mucosal waves of the vocal cord were normal. The jitter and shimmer were lower than that before operation, but the fundamental frequency and harmonic to noise were higher than that before operation. There were no complications. CONCLUSIONThe treatment of hypertrophic ventricular dysphonia with CO2 laser under suspension laryngoscope is safe, reliable and practical.

Hierarchical diagnosis and treatment system has become one of the strategies for overcoming the diffi-culties in medical reform in our country. The important role of health information and its application in hierarchical diagnosis and treatment were thus elaborated in this paper in order to provide reference for the health information construction in establishing hierarchical diagnosis and treatment system at different levels in our country.

The paper objectively analyzes the opportunities and challenges of Internet + medical,and puts forward relevant strategies and recommendations for deeply integratingInternet +into the traditional medical industry in several aspects,including strengthening the construction of Internet infrastructure in the medical industry,regulating the market access and improving the industry standards,as well as establishing and improving relevant supporting laws,regulations and policies.

It is one of the important tasks to promote the development of traditional Chinese medicine culture crea-tive industry in constructing the culture-rich Shandong Province. The major factors that influence the development of traditional Chinese medicine culture creative industry in Shandong Province and the ranks of their importance were thus analyzed by questionnaire survey and hierarchy analysis, respectively. Certain suggestions were put for-ward for the development of traditional Chinese medicine culture creative industry in Shandong Province.

The aim of the study was to investigate the sesquiterpene constituents from the rhizomes of Curcuma wenyujin Y．H．Chen et C．Ling．The isolation and purification of the constituents from the 50％ EtOH extracts of the rhizomes were performed with repeated column chromatography over sillica gel and macroporous resin．Eight sesquiterpenes were obtained and identified as wenyujinlactone A(1),neolitamone A(2),zedoarondiol(3),isozedoarondiol(4),aerugidiol(5),curcumol (6),curdione(7) and (1R,10R)-epoxy-(-)-1,10-dihydrocurdine (8) by means of spectral analysis．Among them,compound 1 was found to be a new eudesmane sesquiterpene lactone,whilst compounds 2-5 were obtained from this plant for the first time．

This study was aimed to offer a scientific basis for the differentiation and control quality of Castanea mol-lissima Blume shell. The determination was given from the morphological identification, microscopical identification and TLC identification. The results showed that through obtained information such as morphological traits, tissue powder and TLC characteristics, the longitudinal section micrographs of C. mollissima Blume shell and the micro-scopic images of tissue powder had been received. It was concluded that the study provided a reliable reference for the identification of the quality control standards of C. mollissima Blume shell.

The key words, social network and author cooperation network in papers ( published in 2003-2014 ) on reform in domestic public hospitals were analyzed using Ucinet and CiteSpace visual softwares with CNKI as the data source.The current situation in reform in domestic public hospitals was revealed by mining its research hotspots, progress and author cooperation .Some suggestions were put forward for strengthening the reform in domestic public hospitals .

Objective To generate recombinant Pichia pastoris for high-copy expression of human tissue factor pathway inhibitor (TFPI). Methods The cDNA encoding human TFPI was inserted into the expression vector pPIC9K and the constructed expression vector rhTFPI-pPIC9K was confirmed by restriction endonuclease analysis and DNA sequencing. The recombinant plasmids were subsequently transformed into Pichia pastoris GS115 cells, and the transformants were confirmed by PCR amplification of the genomic DNA.The recombinant Pichia pastoris with high copies of TFPI cDNA was screened by G418 selection. Western blot and TFPI ELISA Kit were employed to analyzing. The temperature, time and concentration of methanol for the induction of recombinant protein were optimized. Results PCR analysis and DNA sequencing confirmed the successful construction of the expression vector rhTFPI-pPIC9K. Real time quantitative PCR and Western blot analysis demonstrated the positive correlation between TFPI expression level and the copy number of TFPI cDNA in Pichia pastoris cells. Optimization of the induction condition significantly elevated the expression level and activity of TFPI (9.95±0.78 mg/L and 3.91±1.37 U/mL). Conclusion The Pichia pastoris strain with high copy of TFPI expression was successfully constructed, which lays a solid foundation for the further investigation on the function of TFPI and its application in the prevention and therapy of diseases.

AIM:Tostudywhe ther theangiotens in-(1-7)[Ang-(1-7)]/Mas receptor axis protects cardio-myocytes against high glucose (HG)-induced injury by inhibiting nuclear factor-κB (NF-κB) pathway.METHODS:The cell viability was measured by CCK-8 assay.The intracellular levels of reactive oxygen species ( ROS) were detected by DCFH-DA staining .The number of apoptotic cells was tested by Hoechst 33258 nuclear staining .Mitochondrial membrane potential ( MMP) was examined by JC-1 staining.The levels of NF-κB p65 subunit and cleaved caspase-3 protein were de-termined by Western blotting.RESULTS: Treatment of H9c2 cardiac cells with 35 mmol/L glucose (HG) for 30, 60, 90, 120 and 150 min significantly enhanced the levels of phosphorated ( p) NF-κB p65, peaking at 60 min.Co-treatment of the cells with 1 μmol/L Ang-(1-7) and HG for 60 min attenuated the up-regulation of p-NF-κB p65 induced by HG. Co-treatment of the cells with Ang-(1-7) at concentrations of 0.1~30μmol/L and HG for 24 h inhibited HG-induced cy-totoxicity, evidenced by an increase in cell viability .On the other hand, 1 μmol/L Ang-(1-7) ameliorated HG-induced apoptosis, oxidative stress and mitochondrial damage , indicated by decreases in the number of apoptotic cells , cleaved caspase-3 level, ROS generation and MMP loss .However, the above cardioprotective effects of Ang-(1-7) were markedly blocked by A-779, an antagonist of Ang-(1-7) receptor (Mas receptor).Similarly, co-treatment of H9c2 cardiac cells with 100 μmol/L PDTC ( an inhibitor of NF-κB) and HG for 24 h also obviously reduced the above injuries induced by HG.CONCLUSION:Ang-(1-7)/Mas receptor axis prevents the cardiomyocytes from the HG-induced injury by inhibiting NF-κB pathway .
