There was significant difference in the awareness between the two neighborhoods ( P ＜ 0. 01 ). Factors related to their awareness of TB prevention and treatment knowledge included family annual income, educational level, publicity by telecision and broadcasting.

Objective To investigate the clinical diagnostic value of electrocardiogram(ECG)in patients with low blood potassium.Methods From January 2015 to October 2015,patients with low blood potassium were given ECG examination in Yueqing Maternal And Child Health Care Hospital.The relationship between low blood potassium and ECG changes was analyzed.Results The concentration of serum potassium in patients with 0.9 -2.5mmol/L electrocardiogram U wave change,T wave change,ST segment changes,Q -T prolongation,arrhythmia were significantly higher than that of serum potassium concentration in 2.6 -3.4mmol/L patients,and the difference was statistically significant (χ2 =4.63,4.10,4.47,5.01,4.92,all P <0.05).Of patients with hypokalemic ECG showed characteristics of U wave amplitude increased,ST segment depression,T wave amplitude decreased,QT interval prolongation,arrhythmia,of which the most common was premature ventricular contractions,severe low blood potassium could also be occurrence of malignant ventricular arrhythmia.Conclusion Low blood potassium has characteristic changes of ECG,ECG as a noninvasive,simple and quick examination,which is helpful for the rapid diagnosis of low blood potassium.

Objective To evaluate the value of ultrasonic mini probe(UMP) in the diagnosis of lower digestive tract lesions . Methods one hundred and fifteen patients with lesions of lower digestive tract were undergone EUS with UMP (Olympus UM-3R, 20MHz; UM-2R, 12MHz). Results Eighty one cases with colorectal carcinoma appeared as a hypoechoic mass under UMP. UMP had an overall accuracy rate of 82. 7% (67/81) in the diagnosis of depth of infiltrative colorectal carcinoma. The sensitivity and specificity of UMP in the diagnosis of lymph node metastasis were 55. 4% and 68. 8% respectively. All 15 cases with submucosal tumors were diagnosed correctly under EUS except one leiomyoma misdiagnosed as leiomyosarcoma and other 10 and 9 cases were ulcerative colitis and Crohn's diseases respectively. Conclusions UMP has a high accuracy in determining the invasive depth of colorectal carcinoma and submucosal tumors. The preoperative UMP may provide much information and influence on the choice of therapy for colorectal carcinoma and submucosal tumors.

Objective To study and analyze the treatment effect of routine western medicine combined with psychological intervention on senile hypertension. Methods 100 elderly patients with hypertension in our hospital from February 2015 to October 2016 were selected as the subjects. They were randomly divided into the control group and the experimental group, with 50 patients in each group. The patients in the control group were given Kato Pury treatment, and the experimental group was given psychological intervention on the basis of the control group, and pay attention to the psychological state of the patients. The therapeutic effects of the experimental group and the control group were compared and analyzed. Results After the corresponding treatment, the SAS score and SDS score of the experimental group were (41.09±2.26), respectively (38.92±2.15). The SAS score and SDS score of the control group were (53.18±2.41), respectively (48.19±2.56).
