Objective: To evaluate the service competence of 99 smoking cessation clinics in Zhejiang Province, so as to provide reference for the improvement. Methods: The questionnaire, prepared by Tobacco Control Office of Chinese Center for Disease Control and Prevention, was used to investigate all the smoking cessation clinics in Zhejiang Province, to score the basic and developmental indicators, and to assess the qualified rates ( basic indicators >50 points and total scores >60 points ). Results: There were 99 smoking cessation clinics, with 52 in secondary hospitals and 47 in tertiary hospitals. The overall assessment scored from 11 to 96 points, with an average of ( 53.99±16.56 ) points. The smoking cessation clinics in secondary and tertiary hospitals scored ( 53.92±15.88 ) points and ( 54.06±17.45 ) points. The scores of basic and developmental indicators were ( 45.66±12.16 ) points and ( 8.33±5.39 ) points, with the scoring rates of 65.23% and 27.77%. The overall assessment of 43 smoking cessation clinics were qualified and the rate was 43.43%, which was 44.23% in secondary hospitals and 42.55% in tertiary hospitals. Conclusion The qualified rate of smoking cessation clinics in Zhejiang Province was 43.43%, which was similar between second hospitals and tertiary hospitals.

OBJECTIVETo evaluate the effect of Zinc oxide-eugenol cement and Gluma desensitizer on the sheer bond strength of three kinds of dentin bonding agents. The three dentin bonding agents were Zinc phosphate cement, Glass ionomer cement and Super-Bond C&B. To find the theory depending for the using of different protective methods and the selecting of different kinds of dentin bonding agents in prepared abutment teeth.

METHODSThe buccal surfaces of ninety freshly extracted human premolars were flattened to expose an adequate area of lower dentin. Followed by wet-grinding on a series of silicon carbide paper from number 320, 400, 600 grit to produce the dentin bonding surface. The teeth roots were embedded in self-curing resin with the crown out of the resin. The embedded ninety teeth were divided randomly into three groups. The group A was control and the dentin surfaces were not treated. The group B was covered with a paste of Zinc oxide-eugenol cement. The group C was covered with Gluma desensitizer. Calculating the sheer strength between three bonding agents and dentin after the two treatments of dentin surface. The results were statistically assessed with SPSS software. Dentin surfaces were observed with scanning electron microscope (SEM).

RESULTSThe sheer bond strengths of Zinc phosphate cement had significant decrease (P<0.05), especially the C1 group. The sheer bond strengths of Glass ionomer cement and Super-Bond C&B had no significant difference.

CONCLUSIONZinc oxide-eugenol cement and Gluma desensitizer could reduce the sheer bond strength of Zinc phosphate cement with dentin surface. Zinc oxide-eugenol cement and the Gluma desensitizer could not effect Glass ionomer cement and the Super-Bond C&B with dentin.

Objective To observe the effects of acupuncture therapy with finger on back-shu point on acid reflux and lower esophageal sphincter pressure (LESP) of the patients with gastroesophageal reflux disease (GERD). Methods Totally 120 patients of GERD were randomly divided into treatment group and control group through random number table method, 60 cases in each group. Patients in the treatment group were treated with the acupuncture therapy with finger on back-shu point, and patients in control group were treated with lansoprazole tablets and dispersible mosapride citrate for two weeks. Total percentage of acid reflux time, the long time acid reflux episodes, and the longest acid reflux time of two groups were observed six months after the treatment. At the same time, the LESP variation of two groups was followed up six months after the treatment. Results The total percentage of acid reflux time, the long time acid reflux episodes, and the longest acid reflux time decreased significantly in all patients after treatment (P<0.01), while the comparison between groups showed no significant difference (P>0.05). After treatment, LESP of two groups was significantly improved (P<0.05) than before treatment. After stopping treatment half a year, the treatment group had obvious difference (P<0.05) compared with before treatment, while the control group had no significant difference (P>0.05). Conclusion The acupuncture therapy with finger on back-shu point can reduce acid reflux, and achieve the goal of treatment of GERD by improving the lower esophageal sphincter pressure. The duration of improving LESP is longer.

OJBECTIVETo investigate the predictive value of the qualitative assessment of general movements (GMs) for adverse outcomes at 24 months of age in full-term infants with asphyxia.

METHODSA total of 114 full-term asphyxiated infants, who were admitted to the neonatal intensive care unit between 2009 and 2012 and took part in follow-ups after discharge were included in the study. All of them received the qualitative assessment of GMs within 3 months after birth. The development quotient was determined with the Bayley Scales of Infant Development at 24 months of age.

RESULTSThe results of the qualitative assessment of GMs within 3 months after birth showed that among 114 infants, 20 (17.5%) had poor repertoire movements and 7 (6.1%) had cramped-synchronized movements during the writhing movements period; 8 infants (7.0%) had the absence of fidgety movements during the fidgety movements period. The results of development quotient at 24 months of age showed that 7 infants (6.1%) had adverse developmental outcomes: 6 cases of cerebral palsy and mental retardation and 1 case of mental retardation. There was a poor consistency between poor repertoire movements during the writhing movements period and the developmental outcomes at 24 months of age (Kappa=-0.019; P>0.05). There was a high consistency between cramped-synchronized movements during the writhing movements period and the developmental outcomes at 24 months of age (Kappa=0.848; P<0.05), and the results of predictive values of cramped-synchronized movements were shown as follows: predictive validity 98.2%, sensitivity 85.7%, specificity 99.1%, positive predictive value 85.7%, and negative predictive value 99.1%. There was a high consistency between the absence of fidgety movements during the fidgety movements period and the developmental outcomes at 24 months of age (Kappa=0.786; P<0.05), and its predictive values were expressed as follows: predictive validity 97.4%, sensitivity 85.7%, specificity 98.1%, positive predictive value 75.0%, and negative predictive value 99.1%.

CONCLUSIONSCramped-synchronized movements and absence of fidgety movements can predict adverse developmental outcomes at 24 months of age in full-term infants with asphyxia.

Objective To learn the smoke-free environment and smoking status at or below county-level governments of Zhejiang Province, and to promote a smoke-free government.Methods By multi-stage random sampling method, 4 cities were selected in Zhejiang Province, then 4 counties were selected in 4 cities, finally12 governments were selected in 4 counties.With the methods of field observation,interview and questionnaire survey,smoke-free environment and smoking behavior , tobacco related knowledge of civil servants were investigated.Results A total of 12 governments and 405 civil servants were investigated.The smoke-free environment of 12 governments were relatively well.The total smoking rate of civil servants was 17.78%, and the highest was 26.67% in Jiande City, and the lowest were 9.00% in Zhuji City.For the civil servants ,male(26.62%), aged 50-(40.74%),divorced or widowed(40.00%),graduation of technical secondary school (33.33%),cadre of section rank(57.14%),above 20 years' work(28.81%),smoking anywhere at home(50.00%), smoking in certain areas at work(22.95%)were significantly higher.The rate of cognition on the hazards of smoking was lower among the smokers than that of non-smokers (P<0.05).The rate of agreement on MPOWER tobacco control strategies and smoking bans in public places were lower among the smokers than that of non-smokers (P<0.05).Non-conditional logistic regression analysis showed that age of 30-39(OR=9.87,95%CI:1.45-67.29),50-(OR=9.87,95%CI:1.45-67.29), smoking anywhere at home(OR=12.28,95%CI:2.95-51.18),and smoking in certain areas at home(OR=6.57,95%CI:3.07-14.08) may be the risk factors about smoking behavior.Conclusion The situation of smoking control at or below county-level governments in Zhejiang Province was good, and smoking rates has declined.But tobacco related knowledge and behavior of civil servants were relatively insufficient.Aiming at the problems found in the investigation, it is necessary to strengthen education on smoking control among civil servants, and to promote a smoke-free government.

BACKGROUNDMyocardial bridging with systolic compression of the left anterior descending coronary artery (LAD) may be associated with myocardial ischaemia. The clinical outcome in patients with surgical treatment for symptomatic myocardial bridging remains undetermined. This study assessed the middle- and long-term results of surgical treatment for symptomatic myocardial bridging.

METHODSFrom 1997 to 2006, 37,463 patients received selective coronary angiography in the Fuwai Cardiovascular Hospital, Beijing, China. Of these, 484 patients had angiographic diagnosis of myocardial bridging. Of the 484 patients, 35 underwent surgery for treatment of myocardial bridging with significant systolic arterial compression. Among the surgical treatment patients, 24 presented with other cardiac disorders, and the remaining 11 symptomatic patients with isolated myocardial bridging were included in the follow-up study.

RESULTSThe angiographic prevalence of myocardial bridging was 1.3% in this study. The coronary angiographies of the 11 patients revealed myocardial bridging in the middle segment of LAD causing systolic compression > or = 75% (ranging from 75% to 90%). The mean age of patients was 48.4 years. Surgical myotomy was performed in 3 patients and coronary artery bypass grafting (CABG) in 8 patients. Eight patients were operated on with an off-pump approach and 3 with a cardiopulmonary bypass technique after median sternotomy. Conversion to on-pump CABG surgery was necessary in 1 patient because of perforation of the right ventricle. The left internal mammary artery was used in all patients with CABG. The acute clinical success rate was 100% with respect to the absence of myocardial infarction, death or other major in-hospital complications. All of the patients were followed up clinically. The median follow-up was 35.3 months (range: 6 to 120 months). Nine patients were free from symptoms and one of them continued taking beta blockers. The remaining 2 patients with myotomy had atypical chest pain. One received coronary angiography again and no stenosis was found two years after operation; while exercise testing was performed in the other patient and revealed no evidence of myocardial ischaemia. None of the patients sustained a myocardial infarction or other major adverse cardiac events (death or vessel revascularization) during follow-up.

CONCLUSIONSMyocardial bridging is a relatively common angiographic finding. Surgical myotomy or CABG should be limited to patients who are refractory to oral medication. Surgical relief of myocardial ischaemia due to systolic compression of intramyocardial coronary arteries can be accomplished with low operative risk and excellent middle- and long-term results.

OBJECTIVETo identify the relationship between smoking, alcohol intake and hyperlipidemia in fishermen.

METHODS115 fishermen were randomly recruited and divided into case and control groups according to the result of blood lipoprotein. A questionnaire was used to record general information and the history of smoking and alcohol intake. Statistics were gathered to compare the difference of lipoprotein and apolipoprotein level between exposure and control groups and to calculate the OR value of smoking and alcohol intake.

RESULTSThe OR of smoking was 3.417 (95% CI: 1.132 - 10.308), with significant dosage-effect relationship between smoking index and hyperlipidemia. The serum low density lipoprotein-cholesterol (LDL-C) and apolipoprotein (apo) B levels in smoking group was higher than that of control group. The OR value of alcohol intake at early age (early than 20) were 3.275 (95% CI: 1.249 - 8.580) and 4.016 (95% CI: 1.475 - 10.952) respectively. The LDL-C, apoB, the serum total cholesterol (TC)/high density lipoprotein-cholesterol (HDL-C) levels in alcohol abuse group were higher than that of control group.

CONCLUSIONSmoking and alcohol abuse were important risk factors of hyperlipidemia, through changing the level of LDL-C and apoB. There was synergistic action between smoking and alcohol abuse in the development of hyperlipidemia.

OBJECTIVETo study the in vivo stability of normal and anterior cruciate ligament (ACL)-injured knee joint before and after epidural anesthesia under 134 N pre-loading and evaluate the influence of muscular tension on the knee stability.

METHODSEight volunteers with unilateral ACL rupture and normal contralateral knee were enrolled in this study. CT (3D) images and 2 orthogonal images of the knee were captured at 0°, 30°, 60°, and 90° under 134 N pre-loading. The orthogonal images were used to recreate the in vivo knee positions at each of the targeted flexion angles by 2D/3D registration to analyze the tibial translation data.

RESULTSThe anterior tibia translation of both the intact and ACL-injured knees after anesthesia was significantly different from that before anesthesia at all the angles (P<0.05). The anterior tibial translation of the intact knee after anesthesia increased by 1.7 mm at 0°, 2.7 mm at 30°, 2.6 mm at 60°, and 2.3 mm at 90°, as compare to the increase of ACL-injured knee by 4.2 mm, 2.6 mm, 1.2 mm, and 1.6 mm, respectively.

CONCLUSIONThe muscular tension has evident influence on the knee stability in static loading.

OBJECTIVETo study the difference in prevalence of dyslipidemia, hypercholesterolemia, hypertriglyceridemia and low blood high-density lipoprotein cholesterol (HDL-C) between the residents of urban and rural areas of varied regions in China.

METHODSFasting plasma levels of total cholesterol, triglyceride and HDL-C were determined with the enzyme methods for 49,252 subjects aged 18 and over during August to December, 2002.

RESULTSPrevalence of dyslipidemia in Chinese adults aged 18 and over was 18.6%, with 17.0%, 22.9% and 23.4% in the groups of 18-44, 45-59 and over 60 years old, respectively, 22.2% and 15.9% in males and females, respectively, and 21.0% and 17.7% in urban and rural areas, respectively. Prevalence of hypercholesterolemia, hypertriglyceridemia and low blood HDL-C in those aged 18 and over was 2.9%, 11.9% and 7.4%, respectively.

CONCLUSIONSDyslipidemia has become one of important risk factors threatening health of Chinese people, with hypertriglyceridemia and low blood HDL-C as two major types in those aged 18 and over. Prevalence of dyslipidemia was nearly the same in the middle-aged and in the elderly people, and not significantly different in those living in urban areas from those in rural areas. It is very important to pay more attention to earlier comprehensive prevention and control of dyslipidemia.
