S.mutans and S.sobrinus can be easily and reliably identified by colony morphology and biochemical tests.

Objective To investigate the levels and clinical significance of monocyte chemoattractant protein (MCP)-1 and tissue factor (TF) in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD).Methods Forty-nine elderly patients with AECOPD(AECOPD group) and 30 healthy controls (control group) were selected,and AECOPD group was divided into procalcitonin (PCT) increased group (PCT ≥ 0.5 μ g/L,19 cases) and PCT normal group (PCT ＜ 0.5 μ g/L,30 cases) according to the level of serum PCT.The levels of plasma TF,serum MCP-1 and PCT were determined by enzyme linked immunosorbent assay.Results The levels of plasma TF and serum MCP-1 were (203.6 ± 92.9),(152.8 ±99.9) ng/L in AECOPD group,and (136.9 ±24.3),(87.5 ±41.5) ng/L in control group.There were significant differences in the levels of plasma TF and serum MCP-1 between AECOPD group and control group (P＜0.01).The level of plasma TF was positively correlated with serum MCP-1 (r =0.673,P=0.029).The levels of plasma TF and serum MCP-1 were (215.3 ±71.2),(181.1 ±61.6) ng/L in PCT increased group,and (192.4 ±79.7),(137.3 ±74.4) ng/L in PCT normal group.There were significant differences in the levels of plasma TF and serum MCP-1 between PCT increased group and PCT normal group (P＜0.05).Conclusions In patients with AECOPD,hypercoagulability state is activated,and it is more severe in the patients with increased PCT.The level of plasma TF is positively correlated with serum MCP-1 in patients with AECOPD.To monitor the levels of plasma TF and serum MCP-1 is particularly important for elderly patients of AECOPD with hypercoagulability state to prevent cardiovascular,lungs and cerebrovascular thrombotic disease.

BACKGROUND: Radiofrequency catheter ablation (RFCA) in dog triggers myocardial nerve sprouting and sympathetic hyperinnevation. It is possible that RFCA in humans has the same effect. Nerve growth factor (NGF) is a neurons nurture that supports the survival and differentiation of sympathetic neurons and enhances target innervation. Therefore, it is hypothetic that RFCA can increases plasma NGF concentration in humans.OBJECTIVE: To test the hypothesis that RFCA increases plasma NGF concentration in humans.DESIGN: Self-control experiment.SETTING: Department of Cardiology, Tangdu Hospital, the Fourth Military Medical University of Chinese PLA.PARTICIPANTS: Forty-three patients were selected from the Cardiological Department of Tangdu Hospital, the Fourth Military Medical University of Chinese PLA from January to June 2005, including atrioventricular nodal reentrant tachycardia (AVNRT) (n=18), right-sided accessory pathways (RSAP) (n=13) and left-sided accessory pathways (LSAP) (n=12), 20 males and 23 females, ages 28-65 years, all agreed to participate in the study voluntarily.METHODS: Blood samples were obtained from the peripheral veins before ablation and at 6 hours, 1, 3, 5, 7 days after ablation. The plasma concentration of NGF was determined with enzyme-linked immunosorbent assay (ELISA).MAIN OUTCOME MEASURES: The plasma concentration of NGF was determined with ELISA before RFCA and at 6 hours, 1, 3, 5, 7 days after RFCA in each patient.RESULTS: Total 43 patients who were referred for ablation therapy for AVNRT, RSAP and LSAP were involved in the result analysis without loss. Plasma NGF increased at 6 hours after RFCA. Increased NGF continued to 7 days in the RFCA treated patients. The plasma NGF concentrations at 6 hours, 1, 3, 5, 7 days after RFCA in AVNRT, RSAP and LSAP ablations treated patients were (29.72±7.04), (30.94±5.68),(31.39 ±4.92), (31.06 ±4.56), (29.11 ±4.59), (31.77 ±6.25), (30.69 ±5.10),(31.46±4.96), (30.15±4.01), (30.43±3.14), (31.42±6.75), (31.00±5.20),(32.08±4.62), (30.67±3.71), (29.27±2.75) μg/L, respectively, and all more than that before RFCA [(14.89±2.84), (15.00±2.71), (15.51±2.75) μg/L, P ＜ 0.01]. However, there were no significant differences in the NGF levels at 6 hours, 1, 3, 5 and 7 days after RFCA (P ＞ 0.05). The plasma NGF concentration was not significant different among AVNRT, RSAP and LSAP ablation patients at any given time (P ＞ 0.05). The number of RFCA applications, the procedure time and the total energy have no correlation with NGF concentration at any given time instance.CONCLUSION: RFCA increases plasma NGF concentration in humans and lasts for at least 7 days. The number of RFCA applications, the procedure time and the total energy have no correlation with NGF concentration at any given time instance.

Objective:To investigate the behavior of tobacco use among migrants in construction sites and explore the associated factors .Methods: A total of 652 migrants in 10 construction sites were selected in Xi’ an and Tongchuan .Chi-square and logistic regression were used to analyze the influencing factors of tobacco use.Results:The average age of the migrants in the construction site was (38.23 ± 10.61), and males occupied 82.7%(535/647) of the total.The current smoking rate of the migrants was 55.8%(364/652), with 64.3%(344/535) in males and 14.3%(16/112) in females.82.5%(329/399) smokers wanted to quit smoke , however only 52.7%(210/399) had tried quitting smoking in action, and 8.8%(35/399) quitted smoking successfully .Multivariable regression indicated that the migrants who were at lower age , and sick within 2 weeks, had perceived not difficult to stop smoking and who disagree with the benefits of smoking were more likely to try to quit smoking .Conclusion:Migrants in construction sites show their characteristics of old age , low level of health literacy , male-domination , high smoking rate and high intention of quitting smoking .Tobacco control projects should be implemented in construction sites to promote the translation of smoking quitting intention into action .
