Objective To analyse the factors that lead to venous thrombosis among breast cancer patients who need totally implantable access port(TIAP) for chemotherapy. Methods Collecting the clinical data of 60 breast patients admitted to Guanzhou First People's Hospital from May 2018 to April 2019, analysed with SPSS 26.0. Results Catheter-related thrombosis(CRT) occurred in 21 out of 60(35%) patients with TIAP. 30.3% patients with BMI≤24 and 40.74% patients with BMI＞24 had CRT, and incidences of CRT were 20%, 33.34%, 44.12% at the fourth, sixth, eighth therapy respectively. The access terminal position at T5-T8 had 66.67%, 26.09%, 28.57%, 50% of incidence for CRT respectively. 27.5% CRT was with high Ki-67 expression and 50% CRT was with low Ki-67 expression; 47.62% patients with polyurethane catheter and 28.21% patients with silicone catheter got CRT. There were no significant differences in the comparisons above. CRT incidence in ER/PR negative patients was 60%,while 23.08% in ER/PR positive patients (P＜0.05). In HER-2 positive and negative patients, the incidences of CRT were 50% and 23.53% (P＜0.05). Logistic regression noticed that ER/PR negative would increase the incidence of CRT(OR=4.482, 95%CI:1.116～17.998, P＜0.05), low Ki-67 expression would accelerate CRT(OR=7.051, 95%CI:1.513～32.858, P＜0.05). There was no significant difference in the formation of CRT with HER-2 expression(OR=0.254, 95%CI:0.058～1.115, P＞0.05). Conclusion CRT was a common complication of TIAP, which related with ER/PR expression, and should pay attention to during clinical practices.

Objective To analyze the mechanism of aspirin against colorectal cancer(CRC)by bioinformatic analysis. Methods DrugBank 5.1.5 was used to identify direct protein targets (DPTs) of aspirin. The protein-protein interaction (PPI) network of DPTs was constructed and involved signaling pathways were analyzed. CRC-associated gene expression datasets were downloaded from GEO database, and the top twenty differentially expressed genes with the highest degree were screened out as Hub genes. Common genes between the genes associated with the DPTs and the Hub genes of CRC were the potential targets of aspirin against CRC. The potential targets in TCGA database colon adenocarcinoma (COAD) samples were examined. GO functional enrichment analysis and KEGG signaling pathway analysis of the potential targets were performed. The potential targets of aspirin against CRC cells were verified by reverse transcription-polymerase chain reaction (RT-PCR) and western blot (WB). Results Eleven DPTs of aspirin were identified in DrugBank 5.1.5. KEGG signaling pathway showed that 6 genes (EDNRA, IKBKB, NFKB2, NFKBIA, PTGS2, TP53) were associated with the occurrence and development of CRC. By intersecting 20 Hub genes of CRC with genes associated with the DPTs of aspirin, it was found that 5 genes (CDK1, AURKA, CCNB1, MAD2L1, TPX2) might be the potential targets of aspirin against CRC. They were all up-regulated in TCGA-COAD samples, and the gene functions were mainly enriched in cell cycle regulation. The results of RT-PCR and WB showed that aspirin could down-regulate the mRNA and protein expression levels of CDK1, AURKA, CCNB1, MAD2L1 and TPX2 in human colon cancer cells respectively. Conclusion CDK1, AURKA, CCNB1, MAD2L1 and TPX2 could be potential targets of aspirin against CRC by affecting the progress of cell cycle regulation.

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 To investigate the clinical features of infantile allergic proctocolitis and its endoscopic lesions and pathological features. Methods A retrospective analysis of 110 cases of infantile allergic proctocolitis admitted to our hospital from January 2016 to December 2018 and its colonoscopy and pathological results, food allergen-specific IgG, blood routine, fecal routine, serum total IgE detection and treatment. Results Among 110 patients with allergic proctocolitis, 67 were male and 43 were female, 98 were < 6 months old; 26 were breastfed exclusively, 19 were fed milk alone, and 65 were mixed feeding. The clinical manifestations were diarrhea, most of children with bloody stools (93 cases), some children with eczema (23 cases), defecation and crying (67 cases), restless sleep (61 cases), vomiting (8 cases), malnutrition (6 cases); blood eosinophils increased in 63 cases,serum total IgE increased in 21 cases. Food allergen-specific IgG test results:103 cases of milk, 62 cases of eggs. Endoscopic lesions involved the descending colon, sigmoid colon, rectum, 76 cases of transverse colon, 47 cases of ascending colon and 18 cases of ileocecal. Most common manifested as herpes-like changes (106 cases), erosion (97 cases), ulcers (13 cases). Histopathology showed 91 cases of intestinal mucosal eosinophil infiltration, 21 cases of cryptitis and crypt hyperplasia, 18 cases of lymphoid follicle formation and 4 cases of superficial ulcer formation. 18 cases were improved after the mother evaded diet. 8 cases were improved by feding with amino acid milk powder for one week, and then breast milk was gradually introduced; 19 cases were improved after switching to deep hydrolysis or amino acid milk powder. 65 cases were improved after switching to deep hydrolysis or amino acid milk powder and simultaneously the mother evaded diet. Conclusion Infantile allergic proctocolitis lack of insufficient specific manifestations, most of the clinical cases are good, only a few are complicated by malnutrition. Milk is the most important allergen. Diarrhea, history of blood in the stool, elevated blood eosinophils, intestinal herpes-like changes, bowel mucosal eosinophil infiltration, are suggesting a high possibility of allergic proctocolitis. Mothers avoiding diet or switching to amino acids or deep hydrolyzed milk powder treatment is also effective, and this is also the standard of diagnosis of proctocolitis.

Objective In this study, GEPIA database, including TCGA database and GTEx database, were used to explore the potential targets of dihydrotanshinone I on gastric cancer through oxidative stress. Methods Literatures on potential targets of dihydrotanshinone I in gastric cancer were searched in the database;GEPIA database tool was used to analyze the potential mechanism of dihydrotanshinone I on gastric cancer;taking analysis of the correlation between potential target genes and genes expressing key antioxidant stress proteins;We had analysis of expression level of dihydrotanshinone I on potential target genes in gastric cancer patients;and prognostic analysis of dihydrotanshinone I on potential target genes in gastric cancer patients. Results The main targeting genes(proteins) of dihydrotanshinone I on potential target genes were hypoxia inducible factor-1(hif-1) and citrulline histone H3(CITH3), whose genes were HIF1 A and NOS2, respectively;GEPIA database showed that there was a positive correlation between HIF1 A and CAT(P=2e-04, R=0.18), GPX1(P=0.033, R=0.11), or NFE2L2(P=0, R=0.41), while NOS2 only had a positive correlation with SOD1(P=0.21, R=0.18), and no correlation with other three genes. The expression levels of HIF1 A and NOS2 in gastric cancer tissues were higher than those in normal adjacent gastric tissues. The overall survival rate of patients with gastric cancer decreased with the high expression of HIF1 A. Conclusion Dihydrotanshinone I may induce apoptosis of AGS cells through reactive oxygen species mediated oxidative stress, and inhibit the expression of HIF1 A and NOS2, thus inhibit their antioxidative stress, which may improve the overall survival rate of gastric cancer patients.
