Objective To study the clinical significance of the expression of matrix metalloproteinase-9(MMP-9) and E-cadherin(E-cad) in patients with non-small cell lung cancer (NSCLC).Methods Immunohistochemical method (SP) was used to detect the expression of the MMP-9 and E-cad in 62 NSCLC tissues and 18 normal lung tissues.Results The positive expression rate of MMP-9 and the abnormal expression rate of E-cad in NSCLC were closely related to the TNM stages,pathological grades and lymph node involvement (P

Liver metastasis is the leading cause of death from colorectal cancer.Surgical treatment is so far the best choice for the treatment of colorectal liver metastases (CRLM).However,how to suitably select an individualized chemotherapy in perioperative period and surgical time and tool is still under controversy.Therefore,the key factors of improving the prognosis of patients with CRLM include overall evaluation of the patients and their preoperative examination outcomes,dividing patients into different groups based on different therapeutic goals,understanding different therapeutic goals of each group,selecting suitable chemotherapy and targeted therapy,ensuring surgical time (synchronous or stepwise resection) and tools (minimally invasive or open surgery) through multidisciplinary team model.

Objective To investigate the relationship between Atherogenic Index of Plasma(AIP) and the dorsalis pedis artery atherosclerosis in type 2 diabetes. Methods One hundred and twenty-seven patients with type 2 diabetes and 33 healthy individuals were included in the study. The diabetic patients were devided into 2 groups, with( n = 66) or without ( n = 61 ) atherosclerosis. The intima media thickness (IMT) of dorsalis pedis artery were measured by B-mode Doppler ultrasonography. The triglyceride(TG) ,high density lipoproteincholesterol(HDL-C) and other glucolipid metabolic indices were measured in all patients. The AIP was defined as the log value of TG/HDL-C ratio. The one-way ANOVA test was performed to determine the differences among three groups. The relationships between IMT and the other indicators were assessed using Pearson bivariate correlations analysis. The optimal operating point of AIP to diagnose the dorsalis pedis artery atherosclerosis in type 2 diabetes was obtained by drawing ROC curve. Results The AIP value in atherosclerosis diabetic patients,no-atherosclerosis diabetic patients and healthy subjects were 0. 229 ± 0. 132,0. 112 ± 0. 074 and -0. 045 ± 0. 033 respectively. The IMT value were (0. 71 ± 0. 24 ) mm, (0. 49 ± 0. 09 ) mm and (0. 34 ± 0. 15 ) mm respectively. Both indices shown statistical differences among the three groups (Ps = 0. 001 respectively). After adjusting for potential influence factors, AIP showed positive correlation with IMT( r = 0. 315, P = 0. 001 ). The OOP of AIP was 0. 1671 ,the area under the curve was 0. 783. Conclusion AIP was well related to the dorsalis pedis artery atherosclerosis in type 2 diabetes,and the OOP of AIP had good diagnostic reference value in these patients.
