Objective To evaluate the strength of tobacco control at or below county-level governments of Zhejiang Province,to explore the strategies and measures on tobacco control,and promote a smoke-free government.Methods By multistage stratified random sampling method,12 government ageucies were selected in 4 counties.The information of tobacco control strength and smoke-free environment creation was collected by interview and field observation,and the scores were calculated by using the percentage assignment method.An intercept suuvey was carried out in four counties and there were 405 civil servants under investigation.The data were analyzed by frequency statistic and correlation analysis.Results The smoking rate of civil servants was 17.8％,and the secondhand smoking rate was 61.9％;84.7％ of civil servants adnmitted the harm of smoking and 96.8％ admitted the harm of secondhand smoking.Support for forbidding the cigarette advertisements was highest and increasing the cigarette price was the weakest.The scores of smoke-free environment creation of project counties showed that the average score was 50.60,Zhuji and Luqiao got a maximum score of 57.14,Haiyan got a minimum score of 42.86.The scores of tobacco control strength showed that the average score was 82.35,Zhuji got a maximum score of 92.16,followed by Luqiao,Jiande and Haiyan counties,82.35,80.39 and 74.51 respectively.The scores of tobacco control strength,include policy,political will,capacity,and tobacco control efforts were the highest in Zhuji county.The results of correlation analysis showed that the total score of tobacco control strength had significant association with the score of smoke-free environment creation,smoking rate of civil servants,and approval rate of anti smoking in public places (P＜0.05).Conclusion The overall situation of tobacco control strength at or below county-level governments of Zhejiang province is good,but there is a relative shortage of smoke-free environment creation.Civil servants master the knowledge related to tobacco and support tobacco control policy.We should further promote the construction of smoke-free government.More effective smoking control measures should be conducted in order to raise the strength of tobacco control and finally implement the tobacco control legislation.

Objective To understand the prevalence of tobacco use among college students in different populations by sex,age and major,and to provide evidence for smoking control and health decision.Methods A total of 4 638 college students selected in 21 colleges through stratified multi-stage cluster sampling from Zhejiang Province were surveyed by using questionnaire analysis.Indicators such as tried smoking,current smoking,and secondhand smoke exposure,etc.,were calculated by weight on age proportions from the numbers of college students in Zhejiang.Results The prevalence of tried smoking and currcut smoking among college students were 29.72％ and 10.57％,respectively.The prevalence of tried smoking was 46.52％ for men,18.25％ for women;28.57％ for undergraduate,31.53％ for junior college;the prevalence of current smoking was 18.86％ for men,3.86％ for women;8.88％ for undergraduate,13.23％ for junior college students.The snoking rate in college students increased with age,the group of ≥21 Years was the highest (37.87％,16.09％).The lowest level of smoking was medical student (21.76％,2.19％).The prevalence of secondhand smoke exposure in outdoor and indoor places,and dormitory among students were 65.49％,60.33％,and 23.66％,respectively.In the past 30 days,college students have seen tobacco advertisement (47.38％),smoking scenes (60.20％),and got tobacco related gifts (10.40％),free tobacco products (8.93％);college students have seen information about tobacco control (60.50％),cigarette pack warning labels (58.45％),and learned the tobacco knowledge in class in the past 12 months (14.03％).Conclusion Current prevalence of smoking in college students in Zhejiang province remained at a high level,the rate of secondhand smoke exposure is high and in college students there was lack of tobacco control education in class.The results indicated that the policy about tobacco control in school was not enough and the task of health promotion should be taken more arduously.

AIM:To establish a kind of simple and efficient method for cell-free fetal DNA ( cff-DNA) enrich-ment and to investigate its range of applications and the advantages and disadvantages.METHODS:(1) The single nucleo-tide polymorphisms( SNPs) , which linked to paternalβ-thalassemia mutations, were screened.We analyzed the contact be-tween the SNPs inβ-thalassemia gene ( HBB gene) and haploid type by the Haploview software, and then selected these close SNPs which have higher heterozygosity with the HBB gene.(2) We selected 4 cases of different β-thalassemia muta-tions with their husband, and then we used TT-FAST-COLD-PCR to enrich the IVS-II-654 mutations in maternal plasma.If the IVS-II-654 mutation was not detected, we detected the SNP which linked to the IVS-II-654 mutation.Similarly, we used TT-FULL-COLD-PCR to enrich the CD41-42 mutations in the maternal plasma.At the same time, we used the conventional PCR to enrich CD41-42 mutation and IVS-II-654 mutation in the maternal plasma.RESULTS:(1) Nine cases of the SNP ( rs7480526) linked to the mutation at IVS-II-654 in HBB gene, and 11 cases of the SNP ( rs10768683) linked to the muta-tion at CD41-42 in HBB gene were detected.( 2 ) We detected 1 case who inherited the paternal β-thalassemia mutation (IVS-II-654).We did not directly detect patermal IVS-II-654 mutation in maternal plasma, but detected the SNP linked to the IVS-II-654 mutation in the other case and had 100%detection, and 2 cases inherited the paternal β-thalassemia muta-tions (CD41-42) in the maternal plasma by TT-FULL-COLD-PCR and had 100%detection.However, we detected nothing by conventional PCR.CONCLUSION:TT-COLD-PCR is applicable to enrich cell-free fetal DNA in maternal plasma and is a method in the field of noninvasive prenatal diagnosis.

Objective To investigate the value of detecting methylated SEPT9 gene (mSEPT9) in serum and stool in screening colorectal cancer in elderly people.Methods Subjects were divided into three groups, the colorectal cancer group (n=82), the colorectal polyps group (n=80) and the healthy control group (n=100).Real-time quantitative polymerase chain reaction (PCR) was used to detect mSEPT9 in peripheral blood and feces.The relationship between mSEPT9 and clinical and pathological characteristics of colorectal cancer was analyzed.The agreement between serum and stool results was analyzed.Results The positive rate of serum mSEPT9 was 73.2％ in the colorectal cancer group, 6.3％ in the colorectal polyps group and 4.0％ in the healthy control group, with statistical significance between the colorectal cancer group and the other two groups (P＜0.01).The sensitivity and specificity for plasma mSEPT9 detection in screening colorectal cancer were 73.2 ％ and 95.6％, respectively.The positive rate was higher in patients with tumor maximum diameter over 3.0 cm, invasion of the entire serosa layer, lower differentiation or advanced clinical staging (P＜0.05).The detection results of plasma mSEPT9 were in complete agreement with those of stool mSEPT9 from the same patients.Conclusions The expression of mSEPT9 is high in elderly patients with colorectal cancer and has a high sensitivity and specificity for PCR detection.Complete agreement can be seen in results from plasma and feces.Detecting mSEPT9 can be a valuable approach to screening colorectal cancer in the elderly.

Objective To explore the determinants of willingness to quit smoking among pre-pregnancy male smokers, and to provide evidence for smoking cessation strategies. Methods An intercept survey was carried out in four cities in Zhejiang, and there were 552 pre-pregnancy male smokers from 1401 newly wedded couples under investigation. Result The pre-pregnancy male smoking rate was 39.82%, and only 6.88%of pre-pregnancy male smokers were categorized as highly nicotine-dependent. The rate of recent willingness to quit smoking was 50.54%, and reasons for quitting were as follows:a planned pregnancy (62.50%), an example for children (47.70%), and objections from family members (45.22%). The tobacco knowledge among pre-pregnancy male smokers is relatively poor, only 49.64% of smokers were aware 8 points in 11 questions; 88.75% of smoker's wives supported their husband to quit smoking. The associated factors of smoking cessation include: tobacco knowledge (OR=0.38), health self-assessment well (OR=1.90), wife's willing for husband to quit smoking (OR=2.87). Conclusion Compared to ordinary people, the proportion of intention to quit smoking was higher in pre-pregnancy male smokers. To strengthen health education and make wife initiating in husband's quitting programs would be more effective.

Objective To examine the relationship between gender and intraventricular hemorrhage (IVH) in very low birth weight infants (VLBWI) and extremely low birth weight infants (ELBWI).Methods From January 1,1999 to December 31,2012,data on VLBWI and ELBWI,who were admitted to the neonatal intensive care unit of Yuying Children's Hospital within 14 d after birth,were retrospectively collected.The Chi-square test and t test were used to compare neonatal outcomes between male and female infants.The Logistic model was used to analyze the risk factors for IVH.Results A total of 1 008 cases were enrolled,including 615 males and 393 females,895 VLBWI and 113 ELBWI.The incidence of IVH was 15.1％ (152/1 008) and the incidence of severe IVH was 8.4％ (85/1 008).Compared with females,males had a higher total incidence of IVH [17.2％ (106/615) vs 11.7％ (46/393),x2=5.728,P＜0.05] and severe IVH [9.8％ (60/615) vs 6.4％ (25/393),x2=3.896,P＜0.05].These differences were also seen in VLBWI with a birth weight of 1 250 to 1 499 g [IVH:13.7％ (47/344) vs 7.8％ (17/217),x2=4.473,P=0.034; severe IVH:7.6％ (26/344) vs 2.8％ (6/217),x2=5.684,P=0.017].Logistic regression analysis showed that the risk factors for IVH were as follows:gestational age ＜28 weeks (aOR=2.012,95％CI:1.288-3.143,P＜0.05),neonatal respiratory distress syndrome (aOR=l.584,95％CI:1.007-2.492,P＜0.05),invasive mechanical ventilation (aOR=2.743,95％CI:1.826-4.121,P＜0.05),electrolyte disturbance (aOR=2.128,95％CI:1.092-4.149,P＜0.05) and periventricular leukomalacia (aOR=2.901,95％CI:1.312-6.416,P＜0.05),but not male sex (aOR=1.351,95％CI:0.917-1.991,P=0.128).The risk factors for severe IVH were gestational age ＜28 weeks (aOR=2.200,95％CI:1.305-3.708,P＜0.05),invasive mechanical ventilation (aOR=4.714,95％CI:2.809-7.911,P＜0.05) and electrolyte disturbance (aOR=2.232,95％CI:1.047 4.759,P＜0.05),but not male sex (aOR=1.361,95％CI:0.823 2.252,P=0.247).Conclusions Male VLBWI and ELBWI have a higher incidence of IVH and severe IVH,but male sex is not a risk factor for IVH or severe IVH.

Objective To assay the clinical effect of proximal dorsal digital artery pedicled island flap in treatment and sensory reconstruction of adjacent finger soft-tissue defect.Methods The study enrolled 21 cases of soft-tissue defect in 21 fingers treated from January 2013 to January 2014.All the defects were covered with the proximal dorsal artery pedicled island flaps raised from the adjacent finger.Index finger was injured in 7 patients,middle finger in 9 patients,ring finger in 4 patients,and little finger in 4 patients.Defect and flap dimensions varied from 1.9 cm × 1.5 cm to 4.3 cm × 2.3 cm and from 2.0 cm × 1.7 cm to 4.5 cm × 2.5 cm respectively.Donor site was resurfaced with a fullthickness skin harvested from medial side of the upper arm.Postoperative flap appearance and two-point discrimination were evaluated.Total active motion (TAM) of the finger was evaluated after operation.Results All the flaps and skin grafts survived after operation.Duration of the follow-up was 6-18 months (mean,14.7 months).Through the final follow-up,appearance and function of the flap were satisfactory,donor site healed well,and two-point discrimination was 5-9 mm (mean,6.3 mm).TAM evaluation was excellent in 19 patients and good in 2 patients with the excellent-good rate of 100％.Conclusion The proximal dorsal artery pedicled island flap raised from the adjacent finger is an ideal choice in finger soft-tissue reconstruction,for the technique has advantages of high survival rate,satisfactory appearance and sensory function as well as few complications.

OBJECTIVE: To investigate the applicability of EuroQol 5-Dimension 3-Level questionnaire (Chinese Version 1.0) (EQ-5D-3L) in the assessment of life quality of patients with idopathic sudden hearing loss. METHOD: In this retrospect study, the EQ-5D-3L was assigned to 60 patients with idopathic sudden hearing loss before and after drug therapy. Audiometry examinations were undertaken and concomitant symptoms were recorded. A Wilcoxon rank sum test was applicated to the comparisons of results of EQ-5D-3L before and after the treatment, a t-test for results of EQ-VAS and a Kappa measurement for the consistency of certain dimension correlated with the symptoms. RESULT: Sixty patients completed the five questions and visual analog scale of the EQ-5D. A statistically significant changes of pain/discomfort, anxiety/depression before and after the treatment were observed (P < 0.05). The domains of mobility, self-care and usual activities did not show statistically significant different (P > 0.05). The dimension of pain/discomfort was in agreement with the concomitant symptoms. And the result of EQ-VAS was in agreement with the therapeutic outcome. CONCLUSION It is suitable for the EQ-5D to be a general health measure with sensitivity to clinical change in idiopathic sudden sensorineural hearing loss, which monitors the patients' outcomes.

[ ABSTRACT] AIM:To investigate the different dose of perindopril on cardiac function in the rabbits with ische-mic cardiac dysfunction .METHODS:Male rabbits weighing 2.5~3.0 kg ( n=30) were randomly divided into 3 groups (n=10):high dose perindopril group (HD group), low dose perindopril group (LD group) and cardiac dysfunction group (CD group).The Left anterior descending coronary artery of the rabbits was ligatured for model preparation .In HD group, the rabbits were treated with perindopril split normal saline solution (1 g/L)2 mL· kg-1 · d-1 .In LD group, the rabbits were treated with perindopril split normal saline solution (0.33 g/L)2 mL· kg -1 · d-1.In CD group, the rabbits were treated with normal saline solution 2 mL· kg-1 · d-1 .Four weeks after treatment , the cardiac function was measured via echocardiography , the mRNA expression of angiotensin-converting enzyme 2 ( ACE2 ) and angiotensin type 2 receptor (AT2R) was analyzed by real-time PCR, serum angiotensin (Ang)-(1-9) and Ang-(1-7) levels were detected by ELISA. RESULTS:Compared with CD group , the cardiac function of the 2 groups treated with perindopril was significantly im-proved (P<0.01), and more improvement in HD group was observed than LD group (P<0.05).The serum angiotensin ( Ang)-(1-9) and Ang-(1-7) level and the mRNA expression of ACE 2 and AT2R in the 2 groups treated with perindopril were significantly improved (P<0.01).Compared with LD group, the mRNA expression of ACE2 and AT2R and the ser-um levels of Ang-(1-9) in HD group were significant improved (P<0.05), while no difference of serum Ang-(1-7) level was observed.Correlation analysis revealed that the improvement of the cardiac function was associated with serum Ang -(1-9) level, mRNA expression of ACE2 and AT2R (P<0.01), but has no significant correlation with serum Ang-(1-7) lev-el.CONCLUSION:High dose of perindopril may improve more cardiac function in ischemic cardiac dysfunction model in rabbits.The mechanism may relate to increasing serum Ang-(1-7) level to activate AT2R.

Objective: To investigate the inlfuence of angiotensin converting enzyme 2 (ACE2) on lectin-like oxidized low density lipoprotein receptor-1 (LOX-1) protein expression and to explore the protective effect of ACE2 on vascular endothelial cells. Methods: Our work includedin vitro andin vivo studies. For in vitro experiment, the human umbilical vein endothelial cell (HUVEC) were cultured and transfected with replication deficient recombinant adenovirus of ACE2 (Ad-ACE2), and LOX-1 protein expression stimulated by angiotensin 2 was examined by Western blot analysis. Forin vivo study, atherosclerosis plaques were induced in 20 apolipoprotein E-deifcient (ApoE-/-) mice, and then randomly divided them into 2 groups: ACE2 group, the mice received Ad-ACE2 (2.5×109 pfu/ml) injection through caudal vein, EGFP (enhanced green lfuorescent protein) group, the mice received equal replication deifcient recombinant adenovirus of EGFP (Ad-EGFP) injection through caudal vein.n=10 in each group. The animals were executed after 1 month treatment to collect abdominal aorta. Lipid content in atherosclerosis plaque was evaluated by Oil red O staining and LOX-1 protein expression was examined by immunohistochemistry and Western blot analysis. Results: Bothin vitro andin vivo experiments conifrmed that endothelial cell LOX-1 protein expression was signiifcantly inhibited by ACE2 transfection. The lipid content in ACE2 group was obviously lower than that in EGFP group byin vivo study. Conclusion: ACE2 may inhibit LOX-1 protein expression and therefore reduce the progress of atherosclerosis.
