BACKGROUND:The siphon of internal carotid artery is a complex of bending and surrounding structure, which has become a research hot in the field of medical imaging and regional anatomy. There is little research on the hemodynamics of internal carotid artery. Finite element analysis provides the basis for the related dynamics research. OBJECTIVE:To explicit the hemodynamic characteristics of the normal and stenosis internal carotid artery, and to explore the relevant influential factors. METHODS:Finite element model of the siphon of internal carotid artery was built based on 64-slice spiral CT data, and then, three-dimensional models were constructed using Mimics 10.01 software. There were simulations of the normal and post-stenosis blood flows with ANSYS 13.0 CFX software, to observe the changes of hemodynamics, and to analyze their characteristics and differences. RESULTS AND CONCLUSION:The normal blood flow at the siphon of internal carotid artery was in a laminar state, but rotation and turbulent flow formed at the two angle regions. The velocity of external bending zone was slower than that of the internal. The slower was the velocity, the more obvious was the turbulence. The wal shear force decreased at the angle regions, and the wal shear force of external bending zone was smal er than that of the internal. At the region of arterial stenosis, the blood flow was sped, and at the downstream, turbulent flow and low zone of wal shear force were formed. With the increase of stenosis severity, the turbulent flow and low wal shear force area were expanded. Central stenosis showed more obvious effects than the eccentric one. The degree of stenosis and bending at the siphon of internal carotid artery can directly influence the formation of turbulent flow and low wal shear force area, which are more obvious at the external bending zone and central stenosis.

Purpose: This study explored the performance of prenatal ultrasonography in the differential diagnosis of cystic biliary atresia (CBA) and choledochal cyst (CC). Methods: Fetuses diagnosed with hepatic hilar cyst in the second trimester were included in this study. A series of prenatal ultrasound examinations were performed in the second and third trimesters. The diameter of the gallbladder (GB) and hepatic cyst were measured, as well as the wall thickness of the GB. The GB-cyst connection, visibility of the right hepatic artery (RHA), and other concomitant abnormalities were carefully evaluated. A neonatal transabdominal ultrasound examination was performed within 1 week after birth, and clinical data were followed up to 6 months after birth. Results: Between January 1, 2016 and January 31, 2020, 53 fetuses diagnosed with hepatic hilar cyst were recruited. Eight were excluded because they were lost to follow-up. Among the 45 cases included in this study, 10 were diagnosed with CBA and 35 with CC after birth. Statistically significant differences were found in GB width, wall thickness, change in GB width, change in cyst length, GB-cyst connection, and RHA visibility between the CBA and CC groups. GB width showed the best diagnostic performance with an area under the curve (AUC) of 0.899. The combination of GB width, GB wall thickness, and GB-cyst connection yielded a comparable AUC of 0.971. Conclusion The GB should be carefully evaluated in fetuses with hepatic hilar cyst. Prenatal ultrasound findings could provide suggestive parameters for the differential diagnosis of CBA from CC.

Objective:To evaluate the value of contrast-enhanced ultrasound (CEUS) in the diagnosis of solid intraductal papilloma (sIDP) of breast by comparing with fibronenoma of breast (FA).Methods:The CEUS data of 62 cases of sIDP patients and 94 cases of FA patients that confirmed by pathology in the First Affiliated Hospital of Soochow University from October 2016 to January 2021 were retrospectively analyzed. The patients were divided into sIDP group and FA group according to the pathological results. The enhancement speed, enhancement degree, enhancement uniformity, whether the edge after enhancement was polished, whether the enhancement range was enlarged, whether there was a ring unenhanced area in the inner edge of the lesion and whether the inner edge of the unenhanced area was polished were observed in the two groups. SonoLiver software was used to perform offline analysis of the dynamic process of CEUS in the two groups respectively, the enhancement sequence diagram of the lesions was obtained. The pathological result was taken as the gold standard, univariate analysis was applied, and the parameters with statistical significance between the two groups were included in multivariate Logistic regression analysis to establish a differential diagnosis model. The diagnostic efficiency of sIDP was analyzed by ROC curve and diagnostic model.Results:Compared with the FA group, CEUS in the sIDP group mostly showed fast forward, high enhancement, and the enhancement sequence was mostly centrifugal. After CEUS, the lesion edges in the sIDP group were mostly accompanied by unenhanced areas and the inner edges of the unenhanced areas were not intact, and the differences between the two groups were statistically significant (all P<0.05). Binary Logistic regression showed that age, enhancement degree and enhancement order were independent risk factors for sIDP diagnosis. The ROC curve showed that the area under the ROC curve of age, enhancement degree and enhancement sequence combined for the diagnosis of sIDP was 0.874 (95% CI=0.812-0.922), the accuracy was 76.9%, the sensitivity was 67.7%, the specificity was 83.0%, the positive predictive value was 72.4%, and the negative predictive value was 79.6%. Conclusions:There are significant differences in age, enhancement degree and enhancement sequence between sIDP and FA patients. The three-parameter combination can improve the diagnostic efficiency of sIDP.

[摘 要] 目的：基于公开的卵巢癌（OC）单细胞测序数据并利用生物信息学方法构建OC上皮细胞亚型，探究上皮细胞异质性及其对OC肿瘤微环境（TME）的影响。方法：使用GSE118828卵巢癌单细胞数据集的分析得到的8种细胞类型及基因表达矩阵结果，使用反卷积方法估计整体转录组测序（bulk RNA-seq）数据中的细胞组成，依据上皮细胞丰度将OC分为高上皮细胞亚型（C1型）和低上皮细胞亚型（C2型）。分析C1型与C2型患者的生存时间及免疫微环境差异。基于C1、C2型及OC早期（Ⅰ~Ⅱ期）、晚期（Ⅲ~Ⅳ期）组间的差异表达基因（DEG），筛选与OC进展相关的上皮细胞相关基因并分析其对TME的影响。通过人类蛋白质图谱（HPA）数据库数据验证OC进展中上皮细胞相关基因的蛋白表达水平。结果：C1型患者的OS明显优于C2型患者（P < 0.05）。C1、C2型具有完全不同的免疫微环境浸润特性，C1型中辅助性T（Th）细胞、M1型巨噬细胞和激活的树突状细胞浸润程度显著高于C2型（均P < 0.05）。晚期高上皮细胞OC患者HAS1、DAPL1、ADH1B基因表达增加（均P < 0.05），同时，DAPL1基因在OC中的表达与巨噬细胞、Treg细胞的浸润程度呈正相关（P < 0.05）。HPA数据库数据证实，DAPL1蛋白在OC组织中表达显著增加。结论：卵巢癌高上皮细胞亚型可能由于Th细胞、M1型巨噬细胞和激活的树突状细胞的高度浸润发挥抗肿瘤作用；上皮细胞相关基因DAPL1的高表达可能会诱导巨噬细胞、Treg细胞的浸润程度，从而促进OC的进展。

OBJECTIVE To understand the safety of Ilaprazole sodium for injection in clinical practice. METHODS From Jan. 1st 2019 to Feb. 29th 2020， the data of 3 926 valid hospitalized patients receiving Ilaprazole sodium for injection were collected prospectively from 5 third-level hospitals through CHPS， and the post-marketing safety analysis was performed by using retrospective multicenter single cohort study. At the same time， a nested case-control study （the ratio of trial group and control group was 1∶4） was used to confirm the baseline stability of this study cohort and the correlation between adverse reactions and Ilaprazole sodium for injection. RESULTS Among 3 926 patients， 3 patients experienced 5 adverse drug events after using Ilaprazole sodium for injection， with the incidence of 0.076%. There was no serious adverse event， and the occurrence time was 2 days after medication； adverse drug events mainly include elevated liver function indicators （alanine transaminase， aspartate transaminase， total bilirubin）， which were mild and untreated， and all adverse drug events were improved. The results of the nested case-control study showed that the trial group and the control group belonged to the same background baseline， and the occurrence of adverse drug events was more closely related to Ilaprazole sodium for injection. CONCLUSIONS The overall safety of Ilaprazole sodium for injection is relatively high， and the occurrence of adverse events is more related to it.

Objective: To examine genetic variants of familial hematuria (FH) associated genes in 3 families with hematuria with probands initially diagnosed with IgA nephropathy (IgAN). Methods: A retrospective analysis was performed on the clinical data, laboratory tests and genetic test results of three children with hematuria and the probands in three families with hematuria. The families were ascertained at the Department of Pediatrics, Fuzhou General Hospital of Nanjing Military Command from August 2014 to May 2018. Results: The proband of Family One, an 8-year-old boy, manifested gross hematuria. His renal biopsy pathology revealed IgAN. His father also manifested hematuria. Genetic testing showed that the proband and his father carried a heterozygous variant of the CFHR5 gene,533A>G (Asn178Ser). The child of Family Two, a 4-year-old girl, manifested hematuria. Her father, the proband of the family, was 36 years old, and manifested hematuria, proteinuria, high-frequency sensorineural deafness and renal insufficiency. He was diagnosed as IgAN according to clinical manifestations, renal pathology and routine immunohistochemistry without renal biopsy electron microscopy, renal tissue type Ⅳ collagen α3, α4, α5 chains immunofluorescence and skin type Ⅳ collagen α5 chain immunofluorescence. Genetic testing showed that the girl carried a heterozygous variant of the COL4A5 gene,566G>T (Gly189Val), and her father carried the hemizygous variant. The child of Family Three, a 7-year-old girl, manifested hematuria and proteinuria. Her mother, the proband of the family, was 34 years old, and manifested hematuria and proteinuria as well. The proband was diagnosed as IgAN by the same method used for Family Two. The girl′s grandfather died of uremia at the age of 44. Genetic testing showed that the girl and her mother carried a heterozygous variant 539G>A (Gly180Glu)in COL4A5 gene. Conclusions The variant of the CFHR5 gene identified in Family One is of uncertain signifance, and the two variants of the COL4A5 gene identified in Families Two and Three are pathogenic. The probands of Families Two and Three are diagnosed as Alport syndrome. The study suggests that clinicians should examine genetic variants of FH associated genes in families with hematuria when the probands were diagnosed as IgAN by their clinical manifestations, renal pathology and routine immunohistochemistry.
