RESUMO
BACKGROUND@#TRIM proteins are important members of E3 ubiquitin ligases, and many studies have confirmed that TRIM family members play an important role in the development of various tumors. We found that TRIM59 expression level in non-small cell lung cancer (NSCLC) was significantly increased through second-generation sequencing. The purpose of this study was to investigate the expression of TRIM59 in NSCLC and its relationship with the clinicopathological parameters as well as the prognosis of patients.@*METHODS@#The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) datasets were excavated to analyze the expression of TRIM59 mRNA in NSCLC and its relationship with the prognosis of patients; The expression of TRIM59 protein in 90 tumor tissues and adjacent tissues was detected by immunohistochemical staining, and the relationship between the expression of TRIM59 protein and clinicopathological parameters and prognosis was analyzed.@*RESULTS@#Overexpression of TRIM59 mRNA in tumor tissues predicted poor prognosis. The expression level of TRIM59 protein was significantly higher in tumor tissues than in adjacent tissues, and TRIM59 protein expression was correlated with tumor size (P=0.007), tumor differentiation (P=0.009), tumor-node-metastasis (TNM) stage (P=0.003) and lymph node metastasis (P=0.003). Multivariate Cox regression analyses showed that along with TNM stage, overexpression of TRIM59 could be considered an independent prognostic factor for NSCLC patients.@*CONCLUSIONS@#The expression of TRIM59 is closely related to the prognosis of NSCLC patients, and it is an independent risk factor for NSCLC patients.
RESUMO
Objective@#To compare the safety and efficacy between proximal gastrectomy and total gastrectomy and to ascertain the optimized procedure for patients with upper third gastric cancer through meta-analysis.@*Methods@#The English literatures about proximal gastrectomy and total gastrectomy for upper third gastric cancer were searched from PubMed, EMBASE, the Cochrane Library and the Web of Science database and then collected. The quality of enrolled studies was independently assessed by two researchers according to the Newcastle-Ottawa Scale for retrospective studies and Jadad scale for RCT studies. The basic information of the literature and related clinical indicators were extracted. The primary endpoints were 5-year overall survival rate and recurrence rate. The secondary endpoints were operative time, intraoperative blood loss, morbidity of postoperative complication, incidence of anastomotic stenosis and incidence of reflux esophagitis. Considering the influence of tumor staging on postoperative clinicopathological features and prognosis, a subgroup analysis was performed on the literatures including cases of early gastric cancer and those including cases of tumor stage I to IV. Statistical analyses were carried out by the "metafor" and "meta" software packages from RevMan 5.3 software and R software (V3.2.4).@*Results@#Twenty-five literatures involving 3667 patients (proximal gastrectomy for 1483, total gastrectomy for 2184) were finally enrolled for analysis, including 24 retrospective studies with ≥ 5 points and 1 RCT with 3 points, and all the literatures were of high quality. A total of 2516 cases of early gastric cancer were enrolled in 18 articles, including 1027 with proximal gastrectomy and 1489 with total gastrectomy. A total of 1151 cases with stage I to IV were enrolled in 7 articles, including 456 in proximal gastrectomy group and 695 in total gastrectomy group. Five-year survival rate was not significantly different for patients with early gastric cancer between the proximal gastrectomy group and total gastrectomy group (OR=1.16, 95% CI: 0.72 to 1.86, P=0.54). Similarly, there was no significant difference for patients with stage I to IV between the proximal gastrectomy group and the total gastrectomy group (OR=1.19, 95% CI: 0.92 to 1.53, P=0.18). Recurrence rate of early gastric cancer patients was not significantly different between the proximal gastrectomy group and the total gastrectomy group (OR=0.40, 95% CI: 0.05 to 3.16, P=0.39).However, the recurrence rate of the proximal gastrectomy group was higher than that of the total gastrectomy group in patients with stage I to IV (OR=1.55, 95% CI: 1.09 to 2.19, P<0.01), whose difference was statistically significant. There was no significant differences in postoperative complication between the groups, both in patients with early gastric cancer, and in those with stage I to IV (both P>0.05). The incidences of postoperative anastomotic stenosis (OR=3.57, 95% CI: 1.82 to 6.99, P<0.01) and reflux esophagitis (OR=2.83, 95% CI: 1.23 to 6.54, P=0.01) in the proximal gastrectomy group were significantly higher than those in the total gastrectomy group in patients with early gastric cancer.@*Conclusions@#There is no significant difference in long-term survival outcomes between total gastrectomy and proximal gastrectomy for upper gastric tumors. However,incidence of anastomotic stenosis and reflux esophagitis, and tumor recurrence rate after total gastrectomy are significantly lower. The total gastrectomy is recommended as the first choice for advanced upper gastric tumor.
RESUMO
Objective To study the association between renal dysfunction and platelet parameters in elderly patients with early heart failure (HF).Methods 637 patients (350 old-aged and 287 middle-aged) with hypertension,CHD,T2DM admitted to our hospital from January 2013 to December 2014 served as a disease group and 464 subjects (229 old-aged and 235 middle-aged) selected from the 973 Aging Project in September 2007-June 2008 served as a healthy group.Their eGFR and platelets (PLT) were calculated,their plateletcrit (PCT) and mean platelet volume (MPV) were measured.Association between platelet parameters and renal dysfunction was analyzed by binary logistic regression analysis.Results The MPV and PCT were significantly lower in the old-aged disease group than in the old aged healthy group (9.78± 1.45 vs 10.66±0.78,P＜0.01;19.79 ± 6.21 vs 21.82 ± 6.04,P＜0.01).The PLT and PCT were closely associated with the eGFR in two groups (P＜0.05,P＜0.01).Binary logistic regression analysis indicated that the median and high PLT in disease group and the median PLT in healthy group were independently associated with renal dysfunction (OR=0.560,95％CI:0.315-0.996;OR=0.480,95％CI:0.262-0.879;OR=0.483,95％CI:0.249-0.936,P＜0.05).Conclusion Attention should be paid to the effect of PLT and their functional activity on renal function in treatment of early HF patients because aging-induced change of PLT and their functional activity are associated with renal dysfunction.
