Objective To explore the best fat liquefaction prevention measures for gynecological obese patients with abdominal incision.Methods 84 gynecological obese patients with abdominal incision were divided into the observation group(46 cases)and control group(38 cases),according to the negative pressure attract ball placed or not in the subcutaneous fat layer during operation.Patients in both groups were taken abdominal incision physiotherapy.Results The fat liquefaction rate of the observation group was 8.7％,which was lower than that of the control group(26.3％)(x2=4.65,P＜0.05).Conclusion It is very important to keep the incision dry,smooth drainage for prevention and treatment of fat liquefaction in gynecological obese patients after abdominal incision.

Objective To explore the value of the histogram of ultrasound in diagnosing and grading of fatty liver. Methods Ninety subjects were enrolled in normal group, light or moderate to severe fatty liver group (each n=30), respectively. All the subjects underwent histogram of ultrasound of the liver, kidney, spleen and right hepatic vein (RHV), and the ratio of histogram M value of different area were analyzed. Results Statistical differences of the ratio of histogram M value of anterior hepatic tissue of kidney and kidney (AntK) between normal group and two fatty liver groups were detected (P<0.05). The ratio of histogram M value of anterior hepatic tissue of RHV and RHV (AntV) between the normal group and moderate to severe fatty liver group, as well as the light and moderate to severe fatty liver group had statistical differences (P<0.05). When 0.97, 0.78 were used respectively as the critical value of the ratio of histogram M value in diagnosing and grading of fatty liver at AntK and AntV, the sensitivity was all 80.00% and 80.00%, specificity was 85.00% and 70.00%, respectively. Conclusion The ratio of histogram M value of AntK, AntV can be used as the referent index in diagnosing and grading of fatty liver.

Objective To assess the ability of quantitative ultrasound index to predict the severity of CCl4?induced liver fibrosis in a rat model us?ing logistic regression analysis. Methods In a rat model of 40%CCl4?induced liver fibrosis,ultrasound detected the portal vein diameter,blood flow velocity,and Young's modulus. The degree of hepatic fibrosis was determined using a light microscope after hematoxylin and eosin staining of tissue. Results Portal vein diameter and Young's modulus were useful predictors of the severity of liver fibrosis,with statistical significance(P<0.05). Young's modulus was most effective with an R2 value 0.788. Young's modulus combined with the distal diameter of portal vein effectively improved the predictive ability,showing an R2 value 0.821. Conclusion Young's modulus is the most predictive index to assess the severity of liver fibrosis. A combination of multiple indices can improve the ability to predict the severity of liver fibrosis.

s] Objective To analyze the diagnostic value of combined detection of sFIt-1, PLGF and Survivin in early onset preeclampsia. Methods From January 2017 to January 2018, 100 patients with early-onset PE were selected as observation group and 100 healthy pregnant women as control group in Tangshan Maternal and Child health Hospital Gynecology and Obstetrics. The expression levels of sFIt-1, PLGF and Survivin in serum were detected by enzyme-linked immunosorbent assay (ELISA), and the diagnostic value of each index was analyzed separately and jointly. Results The levels of sFIt-1 in the observation group were significantly higher than those in the control group: (36.58 ± 18.34) μg/L vs. (28.43 ± 3.28) μg/L (P<0.05), and the levels of PLGF and Survivin in the observation group were significantly lower than those in the control group: (213.18 ± 48.23) ng/L vs. (398.17 ± 41.19) ng/L, (0.72 ± 0.29) μg/L vs. (1.43 ± 0.32) μg/L (P<0.05); 103 cases of positive sFIt-1, 108 cases of positive PLGF, 107 cases of positive Survivin, 121 cases of positive parallel combined diagnosis and 121 cases of positive series combined diagnosis were found. The sensitivity and negative predictive value of parallel combined diagnosis were significantly higher than those of individualized diagnosis (P<0.05), and the specificity and positive predictive value of series combined diagnosis were significantly higher than those of individualized diagnosis (P < 0.05). Conclusions The combined detection of sFIt-1, PLGF and Survivin in serum can effectively improve the diagnostic accuracy of early-onset preeclampsia and has high clinical value.
