Chinese Journal of Plastic Surgery 2020;36(12):1400-1404
The symmetry of facial contours is an important reference for assessing the attractiveness of human face. Restoring facial symmetry is the main goal in the treatment of many craniofacial conditions; therefore, the accurate measurements of symmetry deviation is highly relevant when planning surgical treatment. Quantitative assessment of facial asymmetry first requires the establishment of a reliable midline or midsagittal plane (MSP). Direct anthropometry, two-dimensional photometry, cephalometric, computed tomography imaging or three-dimensional, etc. can be used for qualitative and quantitative evaluate facial asymmetry. The following review summarize the progress of quantitative method for evaluating facial asymmetry, so as to provide some references for surgeons to accurately, qualitatively and quantitatively analyze the facial contour symmetry of patients before surgery.

Objective To assess the relationship of CYP2C19 gene polymorphism with clopidogrel respon-siveness and the level of EETs in patients with ACS. Methods A total of 123 patients with ACS receiving aspirin combined with clopidogrel dual antiplatelet were enrolled. According to the results of CYP2C19 genotype,patients were divided into three groups:fast metabolic type ,medium metabolic type ,and slow metabolism type. The concentration of EETs and PAIR were compared between three groups. Logistic analysis was used to analyze the risk factors of LCR. Results There were differences statistically in level of EETs and PAIR among the three groups(P<0.05). Logistic analysis showed that the slow metabolism of CYP2C19 gene and lower EETs level were risk factors for LCR. The area under the ROC curve was 0.893(P < 0.05)by EETs level to predict the CYP2C19 genotype. Conclusion The slow metabolism of CYP2C19 gene was an independent risk factor for LCR,while the increase of plasma EETs level was a protective factor.

Objective Through the study of color Doppler ultrasound imaging, to explore the mechanism of portal vein thrombosis for patients with liver cirrhotic portal hypertension splenectomy and its influencing factors. Methods From January 2013 to December 2013, a total of 284 cases of patients with cirrhosis and portal hypertension plenectomy plus pericardial devascularization in 302 Hospital of PLA were reviewed. Color Doppler ultrasound technique was employed to record the thrombosis of portal vein, splenic vein and superior mesenteric vein before and after the surgical procedure. According to the occurrence of portal vein thrombosis after splenectomy, patients were divided into portal vein thrombosis group and non portal vein thrombosis group; the factors that may affect the formation of portal vein thrombus were analyzed by using Logistic regression. Results One hundred and twenty-nine cases of portal vein thrombosis occurred among the 284 patients with splenectomy, the incidence rate was 45.42% (129/284). Logistic regression analysis shows that inner diameters of splenic vein for the group with portal vein thrombosis are significantly different from that of the group without portal vein thrombosis (Z=2.034, P < 0.05), postoperative inner diameter of portal vein (Z=2.037, P<0.05), and prothrombin time (Z=-2.171, P<0.05) are significantly higher in the group with portal vein thrombosis, while preoperative platelet count is significantly lower in the group with portal vein thrombosis (Z=-2.146, P < 0.05); gender, preoperative hepatic artery flow velocity, and blood coagulation time are also the influencing factors of portal vein thrombosis (all P>0.05). Conclusion Color Doppler ultrasound technology can not only monitor, the thrombus formation in portal venous system post splenectomy, it can assess the risk factors of portal vein thrombosis post splenectomy.
