Hepatocyte growth factor(HGF) is a mesenchyme-derived pleiotropic factor which regulates cell growth,cell motility,and morphogenesis of various types of cells,and is thus considered a humoral mediator of epithelial-mesenchymal interactions responsible for angiogenesis,apoptosis and oxidative stress,etc.This article reviewed the relationships between HGF and cardiovascular diseases.

Objective To test the pathogeny of Vibrio cholerae strains of the epidemic in Jinzhou of Hubei Province.Methods Traditional methods of biochemistry,immobihzation test,string test and typing of blood serum were used to test the 6 strains isolated.The virulence gene which was cholera enterotoxin (ct) was detected by PCR.The whole genome DNA finger print of confirmed strains was analyzed by pulsed field gel electrophoresis (PFGE) after digestion respectively with two enzymes Not Ⅰ and Sfi Ⅰ.The DNA fingerprints were analyzed for clusters.Results The 6 strains of Vibrio cholerae were all O139 by traditional laboratory tests;virulence gene was detected in all 6 strains.The banding pattern was the same in the two maps of PFGE.The results of cluster analysis showed that the similarity coefficient of the six strains was 100％.Conclusion The epidemic of Vibrio cholerae is caused by the same pathogenic bacterium which is O139.

OBJECTIVE:To investigate the characteristics of ARDs induced by ciprofloxacin lactate.METHODS:Using philometric method,65 cases developing drug adverse reactions to ciprofloxacin lactate,reported in domestic journals during the past 2 years,were analysed.RESULTS:Of the ARDs in 65 cases,40 were allergic reactions(61.5%),13 reactions of nervous system(12.3%),3 kidney function damage(4.6%),1 liver function damage,1 cardiovascular reaction(1.5%) and 6 reactions of urinary system.CONCLUSION:The ARDs should be under consideration in choice of ciprofloxalin lactate.

A method was developed for determining residual dexamethasone and betamethasone in swine liver by HPLC-MS/MS with isotope dilution. The samples were digested by β-glucuronidase/aryl sulfatase, and extracted) with acetonitrile. Further cleanup was performed on C_(18)) cartridge and liquid-liquid extraction with sodium) carbonate solution. Then the supernatant was dried under nitrogen and residues were dissolved in mobile) phase. The samples were analyzed by HPLC-MS/MS on a Hypercarb C_(18)) column with a mixture of acetonitrile-water-formic acid as the mobile phase. The samples were quantified with the internal standard calibration curve method using isotope dilution. The limit of detection for dexamethasone and betamethasone in swine liver was 0.12 μg/kg and 0.14 μg/kg, respectively. The limits of quantification were 0.42 μg/kg and0.47 μg/kg), respectively. The average recoveries were 97.3%-111.0%, the intra-assay relative standard deviations were 1.85%-5.65% and the inter-assay relative standard deviations were 2.8%-8.0% at spiked levels of 0.75-2.00 μg/kg. There was a good linear correlation (the correlation coefficient is above 0.9997) between the ratio of peak areas of quantitative ion-pair to internal standard and concentration of analyte) in the range of 10-500 μg/L.

Objective To evaluate the impacts of self-management on quality of life of patients with chronic obstructive pulmonary disease (COPD) in community. Method A total of 130 patients with COPD from selected 3 neighbourhood residential committees in Longhua community were randomized into intervention group (65 cases) and control group (65 cases). The control group was treated with conventional health education, the intervention group was treated with self-management education program. Both groups were evaluated by the Chinese version of the chronic disease self-management study measures and SF-36 profile before and after the 6 months intervention. Result After 6 months, the scores of the chronic disease self-management study in the control group were holistic health (3.52 ± 0.64), symptom (18.86 ± 3.06), shortness of breath (3.92 ± 1.74), somatic function (8.15 ± 0.51) and impact on life (22.21 ± 7.14), while the scores in the intervention group were holistic health (2.43±0.43), symptom (15.68±3.66), shortness of breath (2.06 ± 1.30), somatic function (5.73 ± 1.08) and impact on life (16.43 ± 5.17) , and the differences were statistically significant (P<0.01). Compared with the control group, the dimensions and total score of quality of life of the intervention group were (52.41±7.90 vs. 71.63±8.11, P<0.01). Conclusion The effective self-management could improve symptoms, the ability of self-management and their quality of life.

Traditionally, stem cells in adult tissues were believed to be restricted in their differentiation potential and limited to generate the types of cell present in the tissue in which the stem cell resides. Recently, however, many studies indicate that stem cells may display a broader differentiation potential, termed plasticity or transdifferentiation, than what was previously thought. But the validity of this understanding has been challenged by some investigators. In this review, the authors present some standpoints on stem cell plasticity and discuss some phenomena of stem cell plasticity observed on animal models those have been generally accepted currently.

Objective To provide evidence for diagnosis and treatment by investigating the pathogens and drug resistance of immunocompromised host (ICH)pneumonias.Methods Statistical method was used to analyze retrospectively the data of pathogens and drug resistance of ICH pneumonia treated in our hospital in 2014. Results We confirmed 187 cases of ICH pneumonia by pathogen study of 324 patients.Gram-negative bacillus (68.42%)was the main pathogen of ICH pneumonia.Acinetobacter baumanii (AB)accounted for the first place. Staphylococcus aureus infection was still the first of Gram-positive coccus.Conclusion Gram-negative bacillus was the main pathogen of ICH pneumonia in our hospital and the isolated bacteria show strong antibiotic resistance. Therefore,it is necessary to strengthen dynamic monitoring of pathogens in the secretions from ICH pneumonia patients’ lower respiratory tract and drug resistance.It is suggested that clinicians make anti-infection treatment cover drug-resistant bacteria.

BACKGROUND: Smad7 is a major repressible protein in transforming growth factor β(TGF-β1) signal transduction pathway,which possess antifibrotic effects.OBJECTIVE: To construct rat Smad7 eukaryotic vector and to observe the mRNA expression level of TGF-β1, collagen Ⅰ and collagen Ⅲ in rat hepatic stellate cells (HSC)-T6 cell.DESIGN, TIME AND SETTING: The gene recombination and cytology observation experiment was performed at the First Affiliated Hospital of Shihezi University School of Medicine.MATERIALS: pcDNA3.1 (+) plasmid was reserved in the laboratory. E coil DH5α was presented by Key Laboratory of Xinjiang Endemic and Ethnic Diseases, Shihezi University School of Medicine. The HSC T6 cell was provided by Cancer Institute and Hospital, Chinese Academy of Medical Sciences.METHODS: Rat Smad7 cDNA was cloned into eukaryotic plasmid pcDNA3.1(+) to construct Smad7/pcDNA3.1(+) plasmid and transfected it into HSC-T6 ceils by Lipofectmine 2000. The experiment was divided into normal control, empty vector and Smad7 transfected groups, and the positive cells were selected by G418.MAIN OUTCOME MEASURES: The levels of Smad7, TGF-β1, collagen Ⅰ and Ⅲ mRNA was detected by reverse transcriptase polymerase chain reaction, respectively.RESULTS: Smad7 eukaryotic vector was successfully constructed and confirmed by endonuilease digestion and sequencing. Compared to the control and empty vector groups, Smad7 mRNA expression was significantly higher in Smad7 transfected group (P < 0.01 ); and TGF-β1 and collagen Ⅰ mRNA expression was notably reduced (P < 0.01). There was no statistically significant difference of the change of collagen Ⅲ mRNA expression among the three groups (P>0.05). The difference of Smad7, TGF-β1,collagen Ⅰ and Ⅲ mRNA expression had no statistically significant between control and empty vector groups (P_(all) > 0.05)CONCLUSION: Smad7 eukaryotic expression vector is successfully constructed. The Smad7 gene can effectively expressed in transfected HSC-T6 cell, and decrease mRNA expressions of TGF-β1 and collagen Ⅰ.
