Moreover,there was significant differences of CVD risk factors among different departments ( <0.05),which the overall prevalence rate being highest among nurses working in the operating room. Conclusion The nurses with high job stress from tertiary hospital have high risks of CVD,therefore intervention measures should be taken to reduce the risk of CVD.

Objective To investigate the diabetes self-management (DSM) ability and influencing factors in patients with type 2 diabetes in Kunming. Methods A face to face questionnaire survey was conducted on type 2 diabetes patients admitted in the 1st Affiliated Hospital of Kunming Medical University from November 2010 to April 2012. Diabetes self-management instrument ( DSMI) was used to test self-management behavior, and psychological status was assessed by Problem Areas in Diabetes (PAID-5).Results 300 patients participated in the survey.The participant population consisted of 120 males (41.8%) and 168 females (58.2%) .A total of 190 patients (68%) suffered from DM related psychological problems.The mean DSM score was 95.23±20.6, and mean scores for the domain of integration DM care into one’s life, self-regulations, interaction with health professionals,self-blood monitoring glucose,and adherence to recommended regimen were 28.11±6.15,25.22± 5.67,23.06±6.41,10.98±2.96,and 8.75±2.21,respectively. There was no significant difference in the mean score between males and females (P>0.05) .Patients with psychological problems had lower scores in five DSM dimensions than those without psychological problems (P<0.05) . The result of multiple regression showed higher level blood glucose was negatively associated with DSM score, whereas patients with higher income was associated with a higher DSM score (P<0.05) .Conclusions The DSM situation is not good among patients with type 2 diabetes in Kunming, and most of the patients suffer from psychological problem. It is necessary to enhance the effective health education among diabetic patients.

Objective To investigate the action of chondrogenesis differentiation of bone marrow stromal cells (BMSCs) transfected with adeno-hTGF-β1. Methods In the experiment group, replication-deficient a denoviruses carrying human hTGF-β1 complementary DNA (adeno-hTGF-β1 was constructed and applied to transfect to the first generation BMSCs. As a control, each BMSCs was transduced with 200 pfu of adeno-LacZ gene. One day after transfer, BMSCs were trypsinized, counted, and 5×105 cells aliuots were spun down at 500 rpm per minute in 15 ml polypropylene conical tubes and then cultured in a defined medium in an incubator at 37℃ for 21 days. The aggregates were harvested at time points to 21 days and assessed by gross observation, histological analyses and immunohistochemical localization of type Ⅱ collagen. Results When harvested at 21 days, each pellet shrinked to spheroid tissue with apearly opalescence in gross morphology and found to be relatively firm. H.E staining showed elongate dlining cells appeared as perichon drium-like cells at the surface. Some nests of cartilage were observed at the substrate of the tissue. Mature chon drocytes were embeded in the lacuna in the experiment group. In addition, Safranin'O staining confirmed the presence of sulfated proteoglycans in the ECM of chondrogenesis region. Immunohistochemical staining revealed the presence of type Ⅱ collagen in chondrogenesis region. By contrast, HE staining showed no evidence of cartilage formation in the control group. They were fibrous tissue with no architectural feature. Safranin'O staining and Immunohistochemical staining showed no evidence of sulfated proteoglycans or typeⅡ collagen expression. Conclusion BMSCs transfected with adeno-hTGF-β1 could induce its chondro-genesis when aggregate cultured in a defined medium in vitro, laying a foundation for the application of hTGFβ1 gene-transfected BMSCs in cartilage tissue engineering.

In order to research the infrared radiation characteristics of the skin covering Traditional Chinese acupuncture points, which are NeiGuan in the forearm and LaoGong in the center of the palm, we detected continuously the infrared radiation spectra of the human body surface by using Fourier Transform Infrared Spectroscopy. The experimental results showed that firstly, the differences of the infrared radiation spectra of the human body surface were obvious between individuals. Secondly, the infrared radiation intensity of the human body surface changed with time changing. The infrared radiation intensity in two special wavelength ranges (wavelengths from 6. 79 microm to 6. 85 microm and from 13. 6 microm to 14. 0 microm) changed much more than that in other ranges obviously. Thirdly, the proportions of the infrared radiation spectra changed, which were calculated from the spectra of two different aupuncture points, were same in these two special wavelength ranges, but their magnitude changes were different. These results suggested that the infrared radiation of acupuncture points have the same biological basis, and the mechanism of the infrared radiation in these two special wavelength ranges is different from other tissue heat radiation.

Objective: Assess the 4-year antibody against hepatitis B surface antigen (anti-HBs) persistence after revaccination with 3-dose of hepatitis B vaccine (HepB) among low-responder infants following primary vaccination. Methods: According to stratified cluster sampling, a total of 4 147 infants were enrolled and primarily vaccinated with 5 μg HepB derived in Saccharomyces Cerevisiae (HepB-SC) at 0-1-6 months schedule from 75 towns of Jinan, Weifang, Yantai, Weihai prefectures, Shandong Province, China in Aug and Sep 2009. Blood samples were collected one to six months after the third dose of primary immunization and tested for anti-HBs using chemiluminescence microparticle immunoassay (CMIA). 717 infants who appeared low response (10 mU/ml ≤ anti-HBs<100 mU/ml) were revaccinated with 3-dose of HepB. Blood samples were collected from a total of 315 infants one month (T₀), four years (T₁) after revaccination and anti-HBs, antibody against hepatitis B core antigen (anti-HBc) and hepatitis B surface antigen (HBsAg) were detected by CMIA. Information about their birth, primary vaccination were collected. The risk factors associated with positive rate of anti-HBs and GMC of anti-HBs were identified by multiple non-conditional logistic regression analysis and multifactor linear regression model analysis, respectively. Results: Among 315 children, 165 (52.38%) were male and 150 (47.62%) were female. The positive rate was 83.81% (264/315) at T₀ and it decreased to 16.51% (149/529) at T₁. The corresponding GMC decreased from 473.15 mU/ml to 17.37 mU/ml. The average annual decreasing rate of positive rate and GMC was 33.38% and 56.23% from T₀ to T₁. Multivariable analysis showed the positive rate and GMC among those whose anti-HBs titer higher at T₀ were significantly higher at T₁. The positive rate at T₁ among those whose anti-HBs titer 400-<600, 600-<800, 800-<1 000, ≥1 000 mU/ml at T₀ were significantly higher than those whose anti-HBs titer less than 200 mU/ml. The OR (95%CI) of the positive rate was 4.29 (1.03-17.84), 4.53 (1.25-16.47), 4.19 (1.10-15.97) and 9.13 (2.91-28.63), respectively. The GMC at T₁ among those whose anti-HBs titer 400-<600, 600-<800, 800-<1 000 mU/ml and those whose anti-HBs titer ≥1 000 mU/ml at T₀ were higher than those whose anti-HBs titer<200 mU/ml. The b value (95% CI) of GMC was 0.84 (0.06-1.62), 1.13 (0.46-1.79), 1.33 (0.65-2.01) and 1.88 (1.33-2.44), respectively. GMC among full-term infants were significantly higher than premature infants at T₁. The b value (95% CI) of GMC was 0.86 (0.04-1.68). Conclusion Anti-HBs GMC decreased rapidly 4 years after revaccination among low-responder infants, but still kept good protection. The anti-HBs persistence after revaccination was associated with anti-HBs level of titer one month after revaccination.

Cordyceps sinensis(C.sinensis)is a widely used and highly valuable traditional Chinese medicine.Several dipeptides have been detected in C.sinensis,but current scientific knowledge of its chemical makeup remains limited.In this study,an improved approach that integrates offline two-dimensional liquid chromatography(2D LC)separation,precursor ion list,library screening,and diagnostic ion filtering was established to systematically screen and characterize dipeptides in C.sinensis.Offline 2D LC integrating hydrophilic interaction LC and reverse phase separations was established to eliminate interference and identify the target dipeptides.A library containing the potential 400 dipeptides was created,and a precursor ion list with all theoretical precursor ions was adopted to trigger the MS/MS scan with high sensitivity.To identify dipeptides,the type and connection sequence of amino acids were determined according to the product ions.Ile and Leu residues were differentiated for the first time according to the characteristic ion at m/z 69.07.Ultimately,170 dipeptides were identified or tentatively characterized from C.sinensis,and most are reported for the first time in this species herein.In addition,the identified dipeptides were also applied for discrimination among the three Cordyceps species,and 11 markers were identified.The obtained results provide a deeper understanding of the chemical basis of C.sinensis.
