目的 对3例儿童Rotor综合征的临床特点及SLCO1B1和SLCO1B3基因突变分析,提高儿科医生对Rotor综合征的认识。方法 收集广州市妇女儿童医疗中心2018年—2019年确诊的3例Rotor综合征患儿的临床资料,对患儿及其家系成员肝脏常见遗传代谢性疾病二代测序筛查并家系验证结果进行分析。结果 患儿主要临床表现为反复或持续巩膜和(或)皮肤轻度黄染,实验室检查提示高直接胆红素血症。二代测序发现3例患儿均为SLCO1B1基因c.1738C＞T纯合突变和SLCO1B3基因5号内含子区域大片段插入纯合突变。SLCO1B1基因和SLCO1B3基因2处纯合突变均进行了家系验证。文献报道的SLCO1B1基因c.1738C＞T突变是无义突变,可以造成蛋白功能缺失;SLCO1B3基因的大片段插入突变虽暂未有文献收录或报道,但大片段的插入突变可引起移码突变而造成编码蛋白功能丧失。结论 由于基因检测技术的不断进步,Rotor综合征不断被儿科医生所认识。SLCO1B1和SLCO1B3双基因纯合或复合杂合突变是3例Rotor综合征患儿的分子遗传基础。

Objective To better understand Rotor syndrome(RS)in children,the clinical features and SLCO1B1 and SLC01B3 gene mutations were analyzed. Methods The clinical data of the 3 pediatric cases diagnosed in Guangzhou Women and Children's Medical Center between 2018 and 2019 was collected. Genomic DNA was extracted from the children and their family members, and subjected for second-generation sequencing to screen the known genes for liver genetic metabolic diseases. Then the detected mutations were confirmed by Sanger sequencing analysis. Results The main clinical manifestations were recurrent or persistent mild yellowish sclera and/or skin. Laboratory examinations showed hyperbilirubinemia with direct bilirubin elevating. Second generation sequencing showed that all 3 children were c.1738c＞Thomozygous mutations of SLCO1B1 gene and homozygous mutations of large fragment insertion in SLCO1B3 gene intron 5. Two homozygous mutations in SLCO1B1 gene and SLCO1B3 gene were verified in families.SLCO1B1 gene c.1738C＞T mutation,a nonsense mutation reported in references,could lead to protein function loss.A large insertion mutation of SLCO1B3 gene could cause frame-shift mutation which might lead to protein function loss even though it was neither reported in the references nor recorded in SNP database. Conclusion Due to the progress in the clinical application of gene detection technology, RS has been recognized gradually by pediatricians. Homozygous mutations or compound heterozygous mutations simultaneously occurred in SLCO1B1 and SLCO1B3 gene were the molecular genetics base in these cases of RS.

Objective The Guangzhou area is a high-risk area for dengue fever. This study aim to provide a basis for the early diagnosis and prevention of dengue fever by analyzing the clinical and laboratory characteristics and epidemiological analysis of dengue patients in Guangzhou,especially in critically ill patients. Methods A total of 944 patients with dengue fever diagnosed at the First People's Hospital of Guangzhou from 2010 to 2017 were collected. The enrolled patients were divided into 3 groups according to the severity of the disease,the clinical and biological variables between the groups were compared,and multiple regression analysis was used to analyze the effects of risk factors for severe dengue. Results This study retrospectively analyzed the clinical manifestations and laboratory tests of 944 patients with dengue fever in the past 7 years,showing that dengue fever cases in Guangzhou are mainly mild. 77.5% of them have underlying diseases,mainly diabetes (15.4%) and hypertension (34%). Most patients developed high fever (39.05±0.67)℃ at the time of seeing doctors,positive for dengue virus IgM and/or IgG,decreased white blood cells and thrombocytopenia,and abnormal liver and kidney function. AST and LDH values were significantly elevated in critically ill patients compared with mild cases. Patients with coronary heart disease and neoplastic disease have a higher proportion of severe cases. Epidemiological analysis of dengue virus showed an outbreak of dengue fever in 7 years (2014). September-October is the season of high incidence of dengue fever. The incidence of dengue fever was not statistically different between men and women. The high-incidence ages of men and women are 71～80 years old and 51～60 years old,respectively. The incidence rate is the lowest under the age of 10,and the highest in the 50～80 age group. Conclusion Dengue fever patients in Guangzhou are dominated by the elderly,and patients with underlying diseases are at high risk of dengue fever. Dengue fever patients have high fever,positive dengue pathogen detection,blood and liver and kidney dysfunction characteristics. Strengthening the dengue pathogen examination for hyperthermia patients during the high season of September-October is conducive to the early diagnosis and prevention of dengue fever.

Objective To investigate the characteristics and regularity of CT imaging of colorectal cancer liver metas tases. Methods A retrospective analysis of 84 cases of colorectal cancer liver metastases from March 2016 to March 2018 in our hospital. CT dynamic imaging images and clinical data were recorded and statistically analyzed for different blood flow in flows and different enhancement periods. For the CT imaging results, the patients were divided into the left colon group and the right colon group according to the primary tumor site, and the left colon group was grouped according to the blood vessel reconstruction. Results There was no statistic difference in the distribution of left and right lobe between the primary tumor and the left colon in the left colon （P>0.05） . However, in the right colon, the dominant distribution of the right lobe in the metastatic tumor was more than that in the left lobe. The advantage （P=0.00） in the left colon group, the left leaf dom inant distribution of the metastatic tumor of group A was more than that of the right lobe, and the difference was statistically significant （P=0.00）, and the ratio of left and right lobe was about 4∶1;There was no statistic difference in the distribu tion of left and right leaves between group B metastases （P>0.05） . The right leaf dominant distribution of group C metasta ses was more than that of left lobe （P=0.00） . Among 84 patients, a total of 338 liver metastases were found. In the plain scan, the low-density foci were more than the high-density foci, and at least the iso-density foci;in the dynamic CT-en-hanced scan, the annular intensified foci were more than the nodular intensive foci, and the other atypical intensive foci were the least, and the portal vein period enhanced stove display is the clearest. Conclusion The characteristics of CT liver scan in patients with liver metastases from colorectal cancer do have certain regularity, which may provide a theoretical basis for the diagnosis of primary colorectal cancer and early metastasis of colorectal cancer.
