Objective To evaluate the association of body weight with brachial-ankle pulse wave velocity (baPWV) in females.Methods A total of 2 921 residents (≥20 years old) were selected by the stratified cluster random sampling method from March to December 2011.Arterial stiffness was assessed by baPWV.Multivariate logistic regression analysis was used to evaluate the effect of body mass index (BMI) on arteriosclerosis.The predictive value of BMI to evaluate arteriosclerosis was analyzed by using receiver operation characteristic (ROC) curve.Results The prevalence of arteriosclerosis was significantly increased in overweight/obese residents (P＜0.01).BMI was positively correlated with baPWV (r=0.310,P＜0.01).The prevalence of increased arterial stiffness in individuals≥65 years older was higher than that in people of 20-40 or 41-64 years old (x2 values were 677.30 and 347.26,respectively; both P＜0.01).For females of 20-40 or 41-46 years old,the prevalences of increased arterial stiffness in overweight and obese groups were higher than those in normal body weight group (both P＜0.01).In univariate analysis,age,resting heart rate,systolic blood pressure (SBP) and diastolic blood pressure (DBP) were correlated with arteriosclerosis (all P＜0.01).The odds ratio for the prevalence of arteriosclerosis in overweight women was 2.017 (95％ confidence interval (CI):1.637-2.486,P＜0.01) and that in obese women was 2.759 (95％ CI:1.964-3.876,P＜0.01) after adjustment for age,resting heart rate and blood pressure.The area under the ROC curve was 0.693 (95％ CI:0.671-0.715,P＜0.01) to evaluate arteriosclerosis in females and the optimal cut-off point for BMI was 23.42 kg/m2.Conclusions For females,overweight and obesity may be risk factors of arteriosclerosis.The optimal cut-off point for BMI to evaluate arteriosclerosis in women could be 23.42 kg/m2.

Objective To understand the isolation and change of drug resistance of mucoid Pseudomonas aeruginosa in sputum from 2013 to 2015 so as to provide a scientific basis for reasonable clinical use of antibacterial drugs.Methods The isolation,culture and identification were carried out according to the fourth edition of National Clinical Laboratory Operation Rules.The drug susceptibility testing was performed with the use of Kindy-Bauer.The drug susceptibility testing results were judged according to the standards of CLSI 2014.The clinical data were analyzed by software WHONET 5.6.Results Among 1 653 strains of Pseudomonas aeruginosa isolated in the clinical sputum specimens from 2013 to 2015,including 255(15.4%)strains of mucoid Pseudomonas aeruginosa;during the three years,the drugs of highest drug resistance rate was piperacillin,which was 29.0%;the drug resistance rate less than 10.0% had amikacin and piperacillin/tazobactam;the drugs with larger increase range of resistance rate included imipenem,levofloxacin,ciprofloxacin and ciprofloxacin,their resistance rates were increased from 12.5%,9.7%,8.3% and 9.7% in 2013 to 20.5%,17.0%,19.3% and 15.9% in 2015.Conclusion The isolating rate of mucoid Pseudomonas aeruginosa in sputm is gradually increased year by year from 2013 to 2015.At the same time,the drug resistance rates show an increasing trend in recent three years.It is necessary to strengthen the surveillance of drug resistance of mucoid Pseudomonas aeruginosa.

Xiao Zhi Ling Injection is a Chinese herbal aqueous solution of praeparatum which is mainly made of gallnut and alum, it can make a " strengthening body resistance " treatment in polytype tumors, mainly through promoting apoptosis of tumor cells, destructing tumor cells, inhibiting tumor growth, enhan-cing immunity of organism and so on, the clinical effect is certain, with the development of theory and tech-nology in tumor molecular biology, it has become the core of future research that how to further explore Xiao-Zhi-Ling injection to promote tumor cell apoptosis by impacting on related genes, and its lucubrate inevitably provide new hope in gene therapy of cancer.

Objective To construct a recombinant plasmid for expressing the HPV18 E2 gene and develop some materials for HPV18 related disease.Methods The E2 gene of HPV18 was amplified by PCR from PBR322-HPV18 and cloned into PIRES2-EGFP.The sequence of cloned HPV18E2 was confirmed by restriction analysis and DNA sequencing,then transfected into HeLa cells.E2 gene was detected by RT-PCR.Results HPV18 E2 gene fragment was amplified by PCR and ligated to PIRES2-EGFP,then transfected into HeLa cells successfully.The expression of green fluorescence cells was observed by fluorescence microscopy.Specific band could be seen in transfected cells by RT-PCR.Conclusion Recombinant plasmid PIRES2-EGFP is effectively expressed after being transfected into HeLa cells in vitro.

piRNA is a novel class of small single strand RNA that were recently isolated from testes of the mammals. These RNAs are bigger (26～31 nt) than most previously described small RNAs (21～23 nt) and are associated with Piwi-subfamily members of the Argonaute protein family.

The ability of repair and regeneration of central nervous system (CNS) is limited. So many researchers applied themselves to search a valuable cell resource for treating severe diseases of the CNS. Several studies from different laboratories have recently reported that stem cells derived from human umbilical cord blood under certain in vitro conditions can manifest neural features that resemble features of neural-derived cells. In vivo transplantation studies have shown that these stem cells persistently engraft in the CNS, some engrafted cells acquire the characteristics of neurons and glia, and improve functional recovery after central nervous system injury. The existence of stem/progenitor cells with previously unappreciated proliferation and differentiation potential in umbilical cord blood raise the possibility that cord blood may provide an efficient source of cells differentiating into the neural lineage, with a potential to be employed in the therapy of human CNS diseases. The achievement and focuses on the mechanisms and modulation of induction of differentiation and in vitro and in vivo studies in this field was reviewed.

Objective:To develop an interface program between a hospital inspection information system and Hospital Information System(HIS). Such interface program not only guarantees the safety and independence of HIS, but achieves interoperability between HIS and other third-party system.Methods: The interface program between the inspection information system and HIS conforming to hospital demands is developed by using Visual Studio 2008 development platform and WebServices+XML technology.Results: The interface between the inspection information system and HIS operates stably, reliably and efficiently, avoiding manually input information errors, reducing the amount of registration work, and raising work efficiency.Conclusion:WebServices+XML technology is utilized to develop an interface characterized by safety, stability and reliable performance, realizing resource sharing among information systems in the hospital. Besides, the interface can be expanded in the future to adapt to other third-party system, achieving customization.

AlM: To evaluate the clinical effect of 200g/L protein-free calf blood extract eye gel for corneal epithelial defect.METHODS: One hundred and sixty - eight cases of corneal epithelial defect ( 58 cases with herpes simplex keratitis; 24 cases with chemical injury; 85 cases with pterygium operation injury ) were randomly divided into two groups: 84 eyes were treated with protein-free calf blood extract eye gel; 84 cases were treated with basic fibroblast growth factor eye gel ( bFGF ) . The bFGF and protein-free calf blood extract eye gels were used 4 times a day. The treatment course was 7d. Epithelial defect restoration, local symptom and sign were observed.
RESULTS: The difference between pre-treatment and post-treatment was significant ( P<0. 01 ) in the two groups. The effect of protein-free calf blood extract eye gel (83. 3%) group was prior to that of bFGF (69%) for corneal epithelial defect. The effective rate of protein-free calf blood extract eye gel in the herpes simplex keratitis, chemical injury and pterygium operation injury was 72. 4%,69. 2% and 95. 2%. Localized stimulus and adverse reaction of all over the body were not been observed.
