RESUMEN
Objective To explore the clinical application value of minimally invasive endoscopic visual artificial abortion operation system in Painless abortion. Methods 250 cases early pregnant women who underwent minimally invasive endoscopic visual artificial abortion operation system implementation of Painless abortion from June 2015 to December 2015 were selected as visual painless abortion group,while Two hundred and fifty cases early pregnant women who demanded routine painless abortion during the same period were selected as routine painless abortion group. The operation time, the amount bleeding, the villus integrity, the number of cases of once again clear palace operation , the vaginal bleeding time after operation, and the first menstruation recovery time after operation among the pregnant women in the two groups were analyzed. Results There was statistically significant difference in the operation time, amount bleeding, villus integrity, the number of cases of once again clear palace operation , vaginal bleeding time after operation, and the first menstruation recovery time after operation between the two groups ( P<0. 05) . The Observation index of the pregnant women in visual painless abortion group was Obviously superior of that in routine induced abortion group . Conclusion Minimally invasive endoscopic visual artificial abortion operation system implementation of Painless abortion is worthy to be popularized and applied in clinic.
RESUMEN
Objective To investigate the value of Color Doppler ultrasound in hemodynamic changes of non-alcoholic fatty liver disease.Methods 120 cases with non -alcoholic fatty liver disease were selected and divided into the mild group,moderate group and severe group.According to the degree of fatty infiltration of the liver taxono-my,40 cases in each group,hemodynamic changes of each group were detected in Color Doppler ultrasound equip-ment.Results Hepatic venous pulse waveform analysis and comparison constituted of the three groups and control group,the difference was statistically significant (χ2 =25.343,P <0.05).PPVV,MPVV,HARI of the three groups and control group were compared,the difference was statistically significant(F =34.67,51.03,31.06,all P <0.05).Conclusion Color Doppler ultrasound which is used to detect hemodynamic changes in non -alcoholic fatty liver disease had good clinical value,can assess disease progression in patients,can provide the basis for clinical treat-ment.
RESUMEN
Objective To investigate the diagnostic value of ultrasound elastography hardness score and area ratio to identify benign and malignant lesions.Methods 90 patients with breast lumps were selected and divided into the malignant and non -malignant group according to surgical pathology diagnosis,they were 40 cases (a total of 45 tumors)and 50 cases (a total of 57 tumors),two groups of patients were detected in ultrasound elastography,anal-ysis of imaging hardness ratings and area ratio and other information,to investigate the clinical diagnostic value. Results The ultrasound elastography of 50 cases with benign tumor were 0 -2 point,7 cases were 3 -4 point, 7 cases with malignant tumors were 0 -2 point,38 cases were 3 -4 point,the difference between the two groups were statistically significant (χ2 =28.55,P <0.05);The average area ratio of benign tumor was (1.01 ±0.27),malignant tumors was (2.28 ±1.68),the difference between the two groups was statistically significant(t =9.22,P =0.001);the sensitivity,specificity,accuracy of elastography hardness rating in diagnosis of malignant breast tumors were 87.72%,84.44%,86.27%,the area ratio method were 85.96%,86.67%,86.27%,joint inspection of the two groups were 96.49%,95.55%,96.08%,joint inspection had obvious advantages,the difference was statistically sig-nificant(χ2 =16.24,13.58,P <0.05).Conclusion Ultrasound elastography hardness rating combined area ratio has a higher accuracy rate for differentiating benign and malignant breast tumors.
