Objective To demonstrate the influence of PCT concentration and its descent to the prognosis of patients with hospital acquired bacterial pneumonia. Methods The PCT concentration was determined. One hundred and thirteen HAP patients were enrolled from September 2011 and November 2012 , including 64 patients in the non-survival group and 49 patients in the survival group , and 92 non-infected patients in the control group. The relationship between PCT and hospital days and survival rate was analyzed. Results The initial value of PCT in the non-survival group and in the survival group were higher than that in the control group, while the PCT in the non-survival group was the highest, with significant difference (P =0.0002). Taking PCT = 0.78 μg/L as the cut-off value, the sensitivity and specificity to predict the mortality of the HAP patients was 0.66 and 70%, respectively. A significant negative correlation was shown between PCT value and hospital days in the non-survival group. The survival rate of patients with PCT decrease over 50% was higher than that of patients with PCT decrease less than 50% after treatment. Conclusion Dynamic monitoring PCT in patients with bacterial HAP possesses a certain significance.

Objective To study the prevalence of hypertension in She Chinese population of Fujian province and its epidemiological characteristics. Methods Using random sampling method to take advantage of number table, we select a sample of 5350 people who were conducted a questionnaire survey and measured weight, height, blood pressure and other indicators. Results The prevalence of hypertension in She Chinese population of Fujian province was 36. 09%, including undiagnosed number of 1374 cases. The main risk factors of hypertension were age,the level of education, BMI,saltintake. Smoking was not significant with hypertension. The prevalence rate of hypertension among people over 60 years was 63.10%, people comsumed above 8 grams of salt per day had higher pervalence than that in the goup which comsumed below 6 grams or between 6 grams to 8 grams of salt per day. Conclusions The prevalence of hypertension in She had grown rapidly. The She Chinese population should change their lifestyle and hypertension education should perform in this population.
