Clinically,the incidence of portal vein thrombosis(PVT)in patients with cirrhosis can be up to 10％-23％.When PVT is not treated promptly,it may develop to cavernous transformation of the portal vein(CTPV).CTPV can aggravate portal hypertension,accelerate the progression of esophagogastric varices bleeding,refractory ascites,refractory peritonitis,biliary tract diseases,and hepatic insufficiency.At present,noninvasive imaging techniques such as portal vein reconstruction,enhanced CT and ultrasound are mostly used to make the diagnosis and evaluation of CTPV.It is rather difficult to perform portosystemic shunt surgery in patients with CTPV complicated by portal hypertension,which was once regarded as a contraindication for interventional portosystemic shunt procedures.With the improvement of related technologies and surgical instruments,the transjugular intrahepatic portosystemic shunt(TIPS)has become an important treatment for CTPV.This paper aims to make a comprehensive review about the relevant researches concerning the portosystemic shunt surgery in patients with CTPV so as to clarify the importance of TIPS in the treatment of CTPV.

Objective:To investigate the alterations in soft tissue morphology and thickness in the mid-face region of patients with cleft lip and palate (UCLP) secondary to maxillofacial deformity following Le Fort I osteotomy.Methods:A total of 22 patients (16 males and 6 females aged from 17 to 28 years with an average of 20 years) diagnosed with cleft lip and palate secondary to maxillofacial deformity were collected from the Wuhan University Hospital of Stomatology from July 2012 to August 2020. All patients underwent Le Fort I osteotomy. CBCT scans were obtained at T0 (3 days before surgery), T1 (7 days after surgery), and T2 (1 year after surgery). The Dolphin11.95 software and 3D Slicer software were utilized to measure and analyze the soft tissue near the mid-face osteotomy line. Differences in soft tissue thickness before and after surgery were compared.Results:Before and after the operation, the soft tissue thickness at P3, P5, P6, and P8 on the affected side was thicker than that on the healthy side, and the difference was statistically significant, with a P-value of <0.05. At P5, P6, P7, P8, and P9 below the osteotomy line at T2-T0, the degree of postoperative thinning on the affected side was more apparent than that on the healthy side, and there was statistical significance at P6 ( P<0.05). The postoperative soft tissue asymmetry in the Ck region was improved compared with the preoperative one. The preoperative average protruding of the affected side was 0.63 compared with the healthy side, and the postoperative value was 0.17. The preoperative and postoperative Mann-Whitney U tests showed significantly statistical difference. Conclusions:After Le Fort I osteotomy, the facial asymmetry of patients with unilateral cleft lip and palate secondary to maxillofacial deformity is improved. However, there is still a difference in the soft tissue thickness between the healthy side and the affected side, and the change in soft tissue thickness on the affected side is more significant than that on the healthy side.

Objectives To analyze the clinical characteristics and signiflcance of Mycoplasma pneumoniae pneumonia (MPP) combined with secondary thrombocytosis in infants and young children. Methods Clinical features, laboratory and imaging data of the infants and young children with MPP were collected, and compared between the two groups of children with and without secondary thrombocytosis. Results Sixty-seven (67) infants and young children with secondary thrombocytosis (28 males and 39 females, with onset at 2 years and 2 months after birth in average) and 269 infants and young children with normal platelet counts (138 males and 131 females, at 2 years and 3 months after birth in average) were included. Signiflcant longer durations of hospitalization(P =0.018) and fever(P =0.000), higher temperature peak(P =0.000), as well as higher morbidity of refractory MPP(P =0.001) and more complications(P =0.000)were observed in the group of MPP with secondary thrombocytosis. Moreover, the laboratory data of white blood cell count(P =0.000), C-reactive protein(P =0.000),procalcitonin (P =0.000), erythrocyte sedimentation rate(P =0.000)and higher morbidity of multiple pathogen infection(P =0.033) were observed between the two groups.Conclusions More severe clinical manifestations and higher complication morbidity could be observed in the group of MPP combined with secondary thrombocytosis, implicating the value of platelet count in clinical assessment of MPP in infants and young children at early stage.
