Objective To evaluate the effectiveness of tobacco control interventions among employees in centers for disease control and prevention (CDC) in Hebei Province. Methods Tobacoo control interventions, including health education, Quit and Win competition, and founding smokeless CDC, were carried out in CDC system in Hebei Province from May 2006 to June 2008. Surveys on smoking rate of employees and on average cigarette quantity consumed by male employee smokers were conducted at the beginning and the end of the interventions. Results In 2006, 9 931 employees in 174 centers at provincial, city, county level in Hebei Province participated in this study. The overall smoking rate was 25.69%. Male employees had a higher smoking rate (51.28%) than the females (0.68%). The smoking rate of male employees was 50.92%, 49.48% and 51.72% for provincial, city and county CDC levels, respectively. The average cigarettes consumed by one smoker in one day were 15.0. In 2008, 9 139 employees in 189 centers participated in this study. The overall current smoking rate was 25.07%. The smoking rate was 52.26% and 0.43% for males and females, respectively. The smoking rates of male employees in provincial and city CDCs were 43.93% and 46.18%, significantly lower than those in 2006. The smoking rate of male employees in county CDCs was 53.98%, much higher than that in 2006. The average cigarettes consumed by one smoker in one day in 2008 were 12.4, significantly less than that in 2006. The current smoking rate of male employees in smokeless CDCs was 48.0% , significantly lower than 56.9% in non smokeless CDCs. Conclusion Male employees in Hebei Province CDC system had a high smoking rate. Tobacco control interventions play a role in reducing smoking rate and cigarettes consumption.

Objective To study the effects of desflurane on Ca 2+-ATPase activity isolated rat cardiac myocyte plasma membrane ,for the mechanisms of its inhibitory myocardial function.Methods The effects of different concentration desflurane(0%-11%) on Ca 2+-ATPase activity were studied at different calcium concentration(04-20?mol/L) and at 25℃ or 37℃Results Ca 2+-ATPase activity wan depressed by desflurane,the greater inhibitory effect,the higher desflurane concentration,and more severely at low calcium concentration or at 37℃ than at high calcium concentration or at 25℃Conclusions At clinical concentration desflurane produces tha inhibitory effect on rat cardiac myocyte plasma membrane Ca 2+-ATPase activity dose-dependently,which may in part explain its depression on myocardial function.

Objective To evaluate the effects of propofol and thiopontal on calcium and potassium channels in rat ventricular myocytes and to elucidate the underlying mechanisms of their inhibitory effect on myocardium. Methods Freshly isolated ventricular myocytes were prepared from hearts of rats by trypsin. The effects of propofol and thiopental on L-type calcium current(Ica) and delayed rectifier potassium current(IK)were compared using whole-cell patch clump technique. Results Propofol and thiopontal produced a concentration-dependent inhibition of Ica. Peak concentration of propofol(50 ?mol?L~(-1)) and thiopental(100 ?mol?L~(-1)) during induction of anesthesia decreased Ica by 28% and 46% and shifted the steady-state inactivation curve to more negative voltage, but had no effect on the steady-state activation curve. Propofol and thiopental also decreased IK in a concentration-dependent manner, but the effects of both anesthetics on IK were smaller compared with their effects on Ica. Conclusion The findings of this study suggest that the negative inotropic of propofol and thiopental are, at least in part, related to decrease in Ca~(2+) trans-sarcolemmal current by accelerating L-type calcium channel inactivation. Both anesthetics decrease delayed rectifier potassium current, thus partially antagonizing the effect of decreased calcium current.

Objective To study the effect of etomidate on the changes in [Ca2+]i in rat cerebrocortical synaptosomes induced by KCI. Methods Freshly isolated SD rat cerebrocortical synaptosomes were prepared. KCI was used as chemical stimulant. Neurochemical method was employed (Fura-2 was used as calcium indicator) . Etomidate was added (the end concentration was 0.4, 4, 40 and 100 ?mol?L-1 respectively) before and after stimulation with KCI 50 mmol?L-1 to determine the peak and plateau [Ca2+]i in the cerebrocortical synaptomes. Results Before KCI stimulation etomidate inhibited KCl-evoked increase in intra-synaptosomal [Ca2+ ]i in a concentration-dependent manner. The inhibitory ratio of peak calcium concentration was 5%?3% , 11%?6% , 24%?10% and 33%?12% respectively as compared with control. Etomidate at concentration of 40 ?mol?L-1 and above had significant effect on [Ca2+]i. When added immediately after KCI stimulation, 4,40 ?mol?L-1 etomidate significantly increased plateau [Ca2+]i in synaptosomes.Conclusion Etomidate alters KC1-induced calcium dynamics in rat cerebrocortical synaptosomes. Presynaptic calcium channels and calcium removal mechanism are involved in its anesthetic action.

Objective The practical evaluation of Rosco Disk Diffusion method on the clinical antifungal susceptibility test for yeast-like fungi. Methods The Fluconazole susceptibility test was detected by Rosco Disk Diffusion method and NCCLS M27-A broth macrodilution method with 76 yeast-like fungus strains isolated from clinical specimens. Three standard strains were used as the quality control. Results Coincidence rate of the two methods was 90.8%,The sensitive strains detected by one method didn't show resistance in another detection method, and the resistant strains detected by one method yet didn't show sensivity in another.Conclusion Rosco disk diffusion method can be used in clinical detection instead of NCCLS M27-A broth macrodilution method.

Objective To discuss the surgical effect of adult lipomatous tethered cord syndrome (TCS). Methods The clinical data of 29 patients with adult lipomatous TCS were systematically analyzed. Eleven of male and 18 of female,who ranged from 20 to 59 years. All patients were performed filum terminale release and lipoma excision, the clinical outcome after operation was analyzed according to Hoffman grading criteria and visual analog scale (VAS). Results According to Hoffman grading criteria, 9 cases were obviously improved in leg muscle weakness, including 1 case with urination disturbance improved significantly. Also the lower back pain of patients were improved obviously: (2.63 ± 1.30) scores vs. (8.67±0.30) scores, there was significant difference (P<0.05). Conclusions Filum terminale release and lipoma excision can effectively improve the symptom of lower back pain of adult lipomatous TCS patients, meanwhile the symptom of paraparesis can improve appropriate postoperatively. But urinary deficits do not show a significant change.

Objective To determine the relation between the graduation and type of Modic change and low back pain. Methods Ninety-seven patients with low back pain associated with Modic change were enrolled, and the data of clinical were analyzed. The degree of back pain was evaluated by visual analog score (VAS) and Oswestry disability index (ODI). The relation between Modic change and the degree of low back pain was evaluated. Results In 97 patients, the type of Modic change:28 cases (28.9%) were type Ⅰ, 37 cases (38.1%) were type Ⅱ, 11 cases (11.3%) were Ⅱ/Ⅲ, and 21 cases (21.6%) were type Ⅲ. The graduation of Modic change:39 cases (40.2%) were minimal, 34 cases (35.1%) were moderate, and 24 cases (24.7%) were severe. The VAS of type Ⅰ, type Ⅱ, typeⅡ/Ⅲand typeⅢin patients with Modic change were (3.8 ± 0.4), (2.6 ± 0.2), (1.7 ± 0.5) and (1.0 ± 0.6) scores, and there were statistical differences (P<0.05). The ODI scores of type Ⅰ, type Ⅱ, type Ⅱ/Ⅲ and type Ⅲ in patients with Modic change were (11.8 ± 0.7), (8.4 ± 1.1), (5.7 ± 1.3) and (2.0 ± 1.0) scores, and there were statistical differences (P<0.05). Spearman correlation analysis result showed that the type of Modic change was negatively correlated with the intensity of low back pain (r=-0.342, P<0.01). There were no statistical difference in VAS and ODI score among the patients with minimal, moderate and severe of Modic change (P>0.05). Spearman correlation analysis result showed that the graduation of Modic change had no correlation with the intensity of low back pain (r = 0.351, P>0.05). Conclusions The graduation of Modic change does not directly correlate with the low back pain, but the type of Modic lesion is more important.

Objective To investigate the protective effects of erythropoietin (EPO) on myocardium injury after sepsis in rats in order to clarify the mechanisms.Methods The rat models of sepsis were produced by cecal ligation and perforation method (CLP).Ninty-six healthy SD rats were randomly (random number) divided into 3 groups:the sham operation group (Sham group,n =32),the sepsis group (CLP group,n =32),and the EPO treatment group (EPO group,n =32) treated with EPO 1000 IU/kg intraperitoneal injection after the CLP.The observation intervals were set at 3 h,6 h,12 h and 24 h after the surgery.The cardiac hemodynamics of the CLP group were measured.Plasma levels of inflammatory factors and myocardial enzyme indicators were determined by enzyme-linked immunosorbent assay (ELISA) ; Membrane potential levels of chondriosome of myocardial cells,cell apoptosis rates and expressions of nuclear factor-κB p65 of myocardium tissue were detected by flow cytometer; Then the pathological change of myocardium with HE staining was observed under light microscopy.Results (1) Compared with the CLP group,left ventricle systolic pressure (LVSP),left ventricle diastolic end pressure (LVEDP),the maximum rate of left ventricle rise and fall (+ dp/dtmax and-dp/dtmax) in the EPO group improved (P ＜0.05,P＜0.01); (2) Compared with the Sham operation group,plasma levels of tumor necrosis factoralpha (TNF-α),interleukin-6 (IL-6),C-reactive protein (CRP),cardiac troponin-I (cTNI),creatine kinase (CK),lactate dehydrogenase (LDH) and glutamine-oxaloacetic transaminase (GOT) in the CLP group increased at each interval (P ＜ 0.05),and those biomarkers in the EPO group were lower than those in the CLP group (P ＜ 0.05) ; On the contrary,plasma level of anti-inflammatory factor IL-10 in EPO group was higher than that in the CLP group (P ＜ 0.01) ; (3) Compared with the Sham operation group,the cell apoptosis rates in the CLP group increased significantly (P ＜ 0.01),and it decreased obviously in the EPO group (P ＜ 0.01); (4) Compared with the Sham group,membrane potential levels of chondriosome of myocardial cell in the CLP group decreased (P ＜0.01),while it increased in the EPO group in comparison with the CLP group (P ＜ 0.01) ; (5) Pathological changes of myocardium after the CLP could be lessened by the EPO treatment.Conclusions EPO may increase membrane potential levels of chondriosome and decrease the apoptosis rates of myocardial cell in rats after sepsis,and it may reduced the production of inflammatory factors to protect the myocardial cell by down-regulating NF-κB p65.Both increased membrane potential level of chonriosome and decreased inflammatory factor may implicate in myocardium protection thereby improving cardiac function after sepsis.

Objective Metabolic syndrome ( MS), a disorder involving multiple metabolic abnormalities such obesity,hypertension, diabetes or abnormal glucose tolerance and dyslipidemia, has been observed in many patients receiving coronary artery bypass procedures. In this study we try to examine the perioperative effects of metabolic syndrome on the off-pump coronary artery bypass (OPCABG). Methods A prospective study was conducted in 1060 consecutive OPCABG patients who were admited to Beijing Anzhen Hospital from July 2009 to March 2010. The patients were grouped as MS group and non-MS group according to the diagnostic criteria for Chinese metabolic syndrome. The outcomes such as mortality, atrial fibrillation,stroke, staying in ICU for more than three days, use of IABP, ECMO, dialysis, multiple organ dysfunction score ( MOOS) ,postoperative score for cardiac surgery (PSCS), PaO2/FiO2 , heart rate x central venous pressure/mean artery pressure(pressure-adjusted heart rate, PAHR) ,renal and liver function, platelets, and the dosage of vasoactive agents were analyzed and compared between the two groups by x2 test or t test. Results Three hundred and eighty-nine cases were diagnosed with MS among 1060 cases with OPCABG. In the MS group, 17 cases stayed in ICU for more than 3 days, 2 cases died, 76 had atrial fibrillation, 3 had stroke, 18 cases were treated with intra-aortic balloon counterpulsation (IABP). In the non-MS group, 47 cases stayed in ICU for more than 3 days, 12 cases died, 148 had atrial fibrillation, 3 had stroke, 48 cases were treated withIABP, 3 cases received ECMO and 4 cases received dialysis. No significant difference between MS group and non-MS group was identified in the aspects of mortality, atrial fibrillation, stroke, duration of more than three days in ICU, the use of IABP,ECMO, dialysis after OPACBG based on the x2 test(P＞0.05). However, on the operative days, the MODS and PSCS in MS group were significantly higher than that in non-MS group (P ＜ 0.05). MODS 2. 57 ± 1. 62 in MS group vs. 2. 15 ± 1.65 in non-MS group, PSCS 4.27 ±2.15 in MS group vs. 3.92 ±2.29 in non-MS group. PaO2/FiO2 in MS group was significantly lower than that in non-MS group (249.23 ± 110.99 vs. 283. 33 ± 114. 35), P ＜ 0. 01. PAHR in MS group was significantly higher than that in non-MS group (9.98 ±3.54 vs. 9.23 ±3. 88), P ＜0.05. On the first postoperative days, the MODS in MS group was also significantly higher than that in non-MS group (3.05 ±1.64 vs. 2.82 ± 1.72), P＜0.05. PaO2/FiO2 in MS group was significantly lower than that in non-MS group (277.11 ±122.99 vs.318.47 ±143.84), P＜0.05. Conclusion MS was not a predictor for death, atrial fibrillation, stroke, duration of more than three days in 1CU, the use of IABP, ECMO, dialysis after OPACBG. However, MS had a temporary adverse effect on the respiratory and circulatory systems on the operative day and the first postoperative day after OPCABG.
