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 analyze the causes of misdiagnosis of acute myocardial infarction(AMI)with non -specific clinical symptoms.Methods Clinical data of 32 cases of nonspecific clinical symptoms of AMI misdi-agnosis were collected retrospectively,and analyzed misdiagnosis reasons of nonspecific clinical symptoms of AMI. Results Of 32 AMI patients,10 cases were misdiagnosed as digestive system disease,6 cases of cardiovascular system diseases,respiratory diseases in 5 cases,otolaryngology disease in 1 case,4 cases of cerebrovascular disease, immune system disease in 4 cases,endocrine system disease 1 case,1 case of periarthritis of shoulder.Conclusion The diagnosis of atypical AMI patients should follow evidence -based medicine,it can get the correct diagnosis and the best treatment plan and treatment effect in the shortest time,and to reduce mortality and improve prognosis is par-ticularly important.
RESUMO
Objective To compare the clinical efficiency between laparoscopic and open complete mesocolic excision for right-sided colon cancer.Methods Between January 2011 and August 2012,a total of 134 patients with right-sided colon cancer who underwent CME at Fuzhou General Hospital of Nanjing Military Command were divided into laparoscopic (71) and open (63) groups.The intraoperative parameters,pathology,postoperative course and short-term outcomes were compared between groups.The chi-test and the student t test were used for statistics.Result There were no significant differences in the length of distal (P=0.427) and proximal margin (P=0.515),tumor diameter (P =0.440) and number of lymph nodes dissected (P =0.377).Postoperatively patients were followed for up to 12 months,no significant differences were found in local regional recurrence rates (4.2％ vs 1.6％) (P =0.622) and distal metastasis rates (5.6％ vs 3.2％) (P =0.684) between the two groups.The mean operative time (P =0.134) and postoperative complication rate (P =0.977) were similar.The mean intraoperative blood loss was less (P =0.000),bowel flatus passed earlier (P =0.000) and hospital stay shorter (P =0.000) in laparoscopic than that in open group.Conclusions Laparoscopic CME has the same oncologic clearance effects and short-term follow-up result compared with open CME for right-sided colon cancer,and laparoscopic CME is minimally invasive,less bleeding,less pain and quick recovery.
RESUMO
Objective To evaluate the clinical significance of low ligation and high ligation of inferior mesenteric artery (IMA) and lymph nodes dissection on radical resection for rectal cancer.Methods One hundred and fifty-six patients who were diagnosed rectal cancer in our hospital between May 2007 and May 2008 were divided into low ligation group (80 cases)and high ligation group (76 cases).The low ligation group was treated with low ligation of IMA and lymph nodes dissection,the high ligation group was cured by high ligation of IMA and lymph nodes dissection.cases.The IMA lymph nodes metastasis,number of lymph nodes,cancer recurernce rate,5-year survival rate,complication rate were compared and analyzed.Results The rate of lymph nodes metastasis around the origin of inferior mesenteric artery was 15.0％ in the low ligation group,the rate of lymph nodes metastasis around the origin of inferior mesenteric artery was 14.5％ in the high ligation group,and the difference was not statistically significant (P ＞ 0.05).Compared two groups of postoperative recurrence rate,5-year survival rate,anastomotic leakage rate,sexual dysfunction rate and urinary retention rate,there was no significant differences (P ＞ 0.05).The intestinal function recovery time and low anterior resection syndrome incidence of the low ligation group were lower than the high ligation group,there were significant differences (P ＜ 0.05).Conclusions Low ligation of inferior mesenteric artery and lymph nodes dissection can achieve radical resection for rectal cancer.Compared with traditional high ligation of inferior mesenteric artery,there were no differences for patients on recurrence rate,5-year survival rate and complication rate.
RESUMO
OBJECTIVE:To determine content of paeoniflorin in shaofuzhuyu superfine powder granules by HPLC. METHODS: The separation was performed on C18 chromatographic column, the mobile phase was methanol -0.05mol/L KH2PO4(40∶65)with a flow speed at 1ml/min, detection wavelength at 230nm and column temperature at 30℃. RESULTS:The linear range of paeoniflorin was 15.04～752.00?g/ml(r=0.9 998,n=6),the mean recovery rate was 103.3%(RSD=1.53%,n=3).CONCLUSION:This method was simple, accurate, good in recurrence and high in precision, and which can be used for the contents determination and the quality control of the shaofuzhuyu superfine powder granules.
