:1-7
 
目的 探讨SNCG蛋白在卵巢癌组织中的表达情况及临床意义,明确SNCG在人卵巢癌中的表达情况及其恶性程度的关系,为临床卵巢癌的诊断、治疗及预后提供理论依据。方法 收集2010年1月—2015年1月石河子大学医学院第一附属医院收治的具有完整临床病理资料和石蜡切片的119例卵巢癌以及50例正常卵巢患者,用免疫组化方法检测组织中SNCG的表达情况,并分析SNCG的表达与卵巢癌患者临床病理特征及预后的关系。结果 SNCG在卵巢癌组织中的表达高于正常卵巢组织(χ2=73.575,P<0.001);SNCG的表达与卵巢癌患者的肿瘤分期、分化程度、淋巴结转移、达到满意减瘤术、CA125以及HE4水平相关,差异均有统计学意义(P<0.05);与卵巢癌肿瘤的原发部位、腹水、复发及化疗耐药无关,差异无统计学意义(P>0.05);SNCG的过表达与HGSOC患者的PFS、OS相关,差异有统计学意义(P<0.05);多变量Cox比例风险模型分析显示SNCG是HGSOC患者的独立预后因素,与PFS(HR=2.107,95%CI:1.014~3.795,P=0.034)、OS(HR=1.238,95%CI:0.716~1.928,P=0.047)相关。结论 SNCG在卵巢癌中高表达,与患者肿瘤分期、分化程度、淋巴结转移、达到满意减瘤术、CA125以及HE4水平有关,与卵巢癌患者的复发与化疗耐药无关,SNCG蛋白的过表达可作为HGSOC患者的独立预后因素,指导临床诊治。
Objective To detect the expression of SNCG in ovarian cancer tissue and its clinical significance, to clarify the relationship between the expression of SNCG in human ovarian cancer and the degree of malignancy, so as to provide theoretical basis for the diagnosis, treatment and prognosis of clinical ovarian cancer. Methods From January 2010 to January 2015 in First Affiliated Hospital of Medical College of Shihezi University,119 patients with ovarian cancer and 50 patients with normal ovarian which had complete clinical data and paraffin section were selected. Immunohistochemical method was used to detect ovarian SNCG expression, and the expression of SNCG relationship with clinical pathological characteristics and prognosis of patients with ovarian cancer was analyzed. Results The expression of SNCG in ovarian cancer tissue was significantly higher than that in normal ovarian tissue (χ2=73.575,P<0.001). SNCG expression was correlated with tumor stage, degree of differentiation, lymph node metastasis, satisfying tumor reduction, CA125 and HE4 levels in ovarian cancer patients, and the differences were statistically significant (P<0.05). It was not correlated with the tumor primary site, ascites, recurrence of ovarian tumor and chemotherapy resistance, and the differences were not statistically significant (P>0.05).The overexpression of SNCG was correlated with PFS and OS in HGSOC patients, and the differences were statistically significant (P<0.05). Analysis of multivariate Cox proportional risk model showed that SNCG was an independent prognostic factor in patients with HGSOC, related to PFS (HR=2.107,95%CI: 1.014-3.795,P=0.034) and OS (HR=1.238,95%CI: 0.716-1.928,P=0.047). Conclusion The high expression of SNCG in ovarian cancer is related to tumor stage, degree of differentiation, lymph node metastasis, satisfying tumor reduction, CA125 and HE4 expressions, but it is not related to the recurrence of ovarian cancer or chemotherapy resistance. The overexpression of SNCG protein can be used as an independent prognostic factor in patients with HGSOC for clinical diagnosis and treatment guidance.

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.

Objective To evaluate the value of neutrophil-lymphocyte ratio (NLR) in the chemotherapy curative effect and prognosis of patients with advanced colorectal cancer (CRC). Methods Retrospective collection of clinical data from 50 patients with advanced unresectable colorectal cancer who received oxaliplatin-based standard first-line chemotherapy between January 2016 and April 2019. Chemotherapy curative effect was evaluated following 2 chemotherapy cycles. Calculation of neutrophil to lymphocyte ratio (NLR) based on pre-chemotherapy hematology data. The receiver operating characteristic curve was used to determine the optimal cutoff value of NLR,according to patients who were divided into groups of high NLR(NLR≥3.785)and low NLR(NLR≥3.785).The differences between high and low NLR and clinicopathological features, efficacy of chemotherapy, progression-free survival (PFS), and total survival (OS) were compared. COX regression analysis mode was used to analysis of factors affecting PFS and OS in patients with advanced colorectal cancer. Results The differences in tumor differentiation (P=0.030), ECOG score (P=0.003), CEA (P=0.011), CA19-9 (P=0.047) in the high and low NLR groups were statistically significant. The differences in chemotherapy between the two groups was statistically significant (P<0.001), and the high NLR group was less effective. The median PFS of the high and low NLR groups were 3.44 months and 12.84 months, respectively, and the difference was statistically significant (χ2=39.730, P<0.001). The median OS of the high and low NLR groups was 7.59 months and 22.32 months, respectively, and the difference was statistically significant (χ2=40.505, P<0.001). Cox regression analysis suggested that NLR levels and CEA levels were independent prognostic factors for PFS and OS(P<0.05). Conclusion High-level NLR is associated with poor chemotherapy response and poor prognosis in patients with advanced colorectal cancer, and was used as an indicator of chemotherapy efficacy and prognosis.

The group implemented accelerated rehabilitation surgery measures to compare postoperative recovery, hospitalization, and immune function. Results The first exhaust time, the time of getting out of bed, the time of early feeding and the time of catheter extraction were shorter in the observation group than that in the control group(P<0.05). The hospitalization time and total hospitalization cost in the observation group were less than those in the control group(P<0.05). There were no significant differences in Hs-CRP(high-sensitivity C-reactive protein), ALB(albumin), PA(pre-albumin) and Hb(hemoglobin) between the two groups before surgery(P>0.05). On the 3rd day after operation, the indexes of Hs-CRP, ALB, PA and Hb in the observation group were better than those in the control group(P<0.05). Conclusion Accelerated rehabilitation surgery is of great value in the development of laparoscopic assisted colorectal cancer radical surgery.

目的 利用GEPIA数据库,包括TCGA数据库和GTEX数据库,探讨二氢丹参酮I通过氧化应激治疗胃癌的潜在靶点。方法 在数据库中检索二氢丹参酮I在胃癌中潜在靶点的文献,利用GEPIA数据库工具分析二氢丹参酮I在胃癌中的潜在作用机制,分析潜在靶基因与表达关键抗氧化应激蛋白基因的相关性;二氢丹参酮I对胃癌潜在靶基因表达水平的分析;二氢丹参酮I对胃癌潜在靶基因的预后分析。结果 二氢丹参酮I对潜在靶基因的主要靶向基因(蛋白)为缺氧诱导因子-1(hif-1)和瓜氨酸组蛋白h3(cith3),其基因分别为HIF1 A和NOS2;GEPIA数据库显示HIF1 A与CAT(P=e-04,r=0.18)、GPX1(P=0.033,r=0.11)或NFE2L2呈正相关。(P=0,r=0.41),而NOS2与SOD1仅呈正相关(P=0.21,r=0.18),与其它三个基因均无相关性;HIF1 A和NOS2在胃癌组织中的表达水平高于正常胃旁组织;HIF1 A的高表达降低了胃癌患者的总生存率。结论 二氢丹参酮I可通过活性氧介导的氧化应激诱导AGS细胞凋亡,抑制HIF1 A和NOS2的表达,从而抑制AGS细胞的抗氧化应激,提高胃癌患者的总生存率。
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.
