ABSTRACT
Objective To obtain Hangzhou residents' awareness, understanding, demands, and intentions of health examination and explore the factors influencing health examination. Methods Totally 1 183 residents (male: 542, female: 641, aged from15 to 80 years) were investigated by mean of questionnaire which included demographic characteristics, health status, medical behavior and awareness, the subjective reasons of unwilling to take health examination, the intention of choosing an institution, and the data of questionnaire were analyzed using single factor Chi-square test and conditional logistic regression analysis. Results Single factor Chi-square test showed that the factors affecting health examination participation which have statistical significances were as follows, gender (χ2=11.61,P=0.000), age (χ2=9.09, P=0.028), residence registration (χ2=44.16,P=0.000), marital status (χ2=8.96,P=0.03), educational backgroud (χ2=17.33,P=0.000), employment status (χ2=7.97,P=0.005), personal monthly income (χ2=22.82, P=0.000), having any kinds of health insurance (χ2=16.08,P=0.000), and the health examination fees paid by company (χ2=44.78,P=0.000). Conditional logistic regress analysis showed that the related fators which affecting the peoples participating rates of taking health examination are gender (P=0.003, OR=1.782), residence registration (P=0.000, OR=2.208), personal monthly income (P=0.009, OR=1.307), taking any kinds of insurance (P=0.004,OR=2.913)and the company organizing and paying for the healthy examination or not (P=0.000,OR=1.923). Conclusion The participation rates of taking health examination were affected by the factors such as male, younger than 45 years old, divorce, temporary residents, the jobless, low educational diploma and income, not having any insurance, taking the health examinaiton at their own expense and so on.
ABSTRACT
Objective To explore the relationship between body mass index(BMI) and blood lipid,physical activity,blood pressure and electrocardiagram(ECG) lead V1 P wave terminal force(PTFv1).Methods A total of 1 548 heahy volunteers with no diabetes,cardiovascular disease and hypertension were assigned to the normal control,overweight or obese groups.The correlation between BMI and lipid profiles was analyzed.One hundred and ninty-five volunteers without exercise-induced asthma and emergency were required to do treadmill exercise test to analyze the correlation between physical activity score,blood maximum pressure and Ptfv1.Results BMI was significantly different by blood lipid (Cholesterol:F=7.57,P＜0.05; Triglyceride:F=73.40,P＜0.05),physical activity score(F=4.52,P＜0.05) and blood maximum pressure(F=1 1.75,P＜0.05) other than age(P＞0.05).In the three groups,treadmill exercise test was significantly different in Ptfv1(normal control group vs obese group:x2=5.67,P＜0.05; overweight group vs obese group:x2=6.17,P＜0.05).Conclusion With the increase of BMI,blood lipid and maximal systolic pressure were increased,although physical activity score was decreasing.Abnormal PTFv1 was significantly associated with BMI.increased Treadmill exercise test may be helpful in screening potential cardiovascular disease among high risk obesity populations.
ABSTRACT
Objective To evaluate the diagnostic value of power Doppler ultrasonography through vagina in malignant trophoblastic tumor(MTT).Methods The features of power Doppler flow imaging of 43 cases with MTT were studied retrospectively.The imaging differences in normal group,benign gestational trophoblastic tumors and malignant gestational tropho-blastic tumors were compared,and the relationship between imaging character and benign or malignant gestational trophoblastic tumors was analyzed.At the same time,the change of blood flow in uterine intramuscular layer was obeserved before and after chemotherapy combined with β-hCG.Results The blood folw character of uterine intramuscular layer in normal group was punctate and scattered blood flow signal,flow shape was regular;The blood folw character of uterine intramuscular layer in benign gestational trophoblastic tumors group was short pole blood flow signal,flow shape was less regular;The blood folw character of uterine intramuscular layer in malignant gestational trophoblastic tumors group was very rich blood flow signal,flow shape was anomalistic; After chemotherapy,the extent and diameter of the blood folw of uterine intramuscular layer was decreased seriously,while the β-hCG reduced.Conclusion PDI had diagnostic value in MTT and could be seemed as a guide for observing the chemotherapeutic effect and prognosis of MTT.
ABSTRACT
Objective To investigate the diagnostic value of color doppler transvaginal scan for patients with ectopic pregnancy. Methods Transvaginal scan and transabdominal scan were used to inspect 109 cases that were clinically doubted as early ectopic pregnancy. 126 cases only received transabdominal scan were as control group. Results Through transvaginal scan,35 cases were found as early unruptured ectopic pregnancy after they stop men-stru-ation about 35 to 42 days. The inspected time of the other 74 cases and control cases was post-poned obviously. All cases were compared with laparoscopy or skive belly operation and got the consilient rate of 97%. And the inspected time was earlier for 11. 3 days than the contrel group. This was a notable discrepancy (P < 0.01). Conclusion Transvaginal scan could improve the inspected rate for the early ectopic pregnancy greatly. It had more value than other methods,so it was worth being utilized widely.
