Objective To investigate the expressions of matrix metallopro-teinase-7 (MMP-7),basic fibroblast growth factor (bFGF)in NSCLC,and to elucidate the correlations among MMP-7,bFGF and MVD, as well as their relationships with cancer metastasis in NSCLC.Methods The expressions of MMP-7,bFGF and MVD were detected by immunohistochemical SP method in 80 cases of NSCLC and 40 cases of normal lung tissue,compare the expression of MMP-7 and bFGF in NSCLC and normal lung tissue,and then invest the rela-tionship between their expression and lymph node metastasis in NSCLC.The MVD was investigated within the CD34 positive slides,check the relationship between MVD and the expression of MMP-7 ,bFGF in NSCLC, and also its relationship with histology type,differentiation degree,lymph node metastasis and TNM stage. Results The positive ratesof MMP-7 and bFGF were significantly higher in NSCLC than those in normal lung tissue (70.0% vs 1 2.5%,χ2 =35.276,P =0.000;65.0% vs 1 0.0%,χ2 =32.41 1 ,P =0.000).The posi-tive rates of MMP-7 and bFGF were also significantly higher in group with lymph node metastasis compared to those group without lymph node metastasis (83.0% vs 51 .5%,χ2 =9.1 39,P =0.003;80.9% vs 42.4%,χ2 =1 2.584,P =0.000).The numbers of MVD were significantly higher in cases with MMP-7 and bFGF posi-tive expressions than those in cases with MMP-7 and bFGF negative expressions (46.78 ±1 1 .1 1 vs 31 .1 2 ± 7.62,t =5.831 ,P =0.000;45.05 ±1 0.97 vs 34.77 ±8.56,t =5.364,P =0.000).The number of MVD in group with lymph node metastasis was also significantly higher than that in group without lymph node metasta-sis (61 .32 ±21 .61 vs 40.52 ±1 8.31 ,t =3.865,P =0.008).The number of MVD in staging Ⅲ-Ⅳ group was significantly higher than that in stagingⅠ-Ⅱgroup (55.28 ±1 5.64 vs 41 .73 ±1 6.48,t =2.531 ,P =0.01 3).Conclusion The expression levels of MMP-7 and bFGF in NSCLC are high,and the positive rates of MMP-7 and bFGF are correlated with the lymphnode metastasis.The numbers of MVD are significantly higher in cases with MMP-7 and bFGF positive expressions than those in cases with MMP-7 and bFGF negative expre-ssions.MVD is correlated with lymph node metastasis and the TNM stage.It suggests that the expressions of MMP-7,bFGF and MVD may involve in the invasion and metastasis of NSCLC.

The Kirkpatrick Model has been widely used in nursing staff training. This paper reviews the development, content and application of Coriolis evaluation model in nursing training, in order to provide reference for improving nursing training methods and improving the professional quality of nursing staff.

OBJECTIVE To investigate the effects of renally inappropriate medication （RIM） on the frailty of elderly patients with diabetes. METHODS The data of elderly patients with diabetes mellitus admitted to a third-grade class A hospital in Yunnan province from January to December 2022 were collected， and Beers criteria （2019 edition） and Chinese version of FRAIL scale were used to evaluate RIM and the frailty of the patients； the patients were divided into the trial group （with RIM） and the control group （without RIM） according to whether there was RIM. The propensity score matching was used to balance confounding factors between two groups， and the influence of RIM on the frailty of elderly diabetic patients was analyzed by the Logistic regression model. RESULTS Among the 367 patients， 80 patients （21.80%） had RIM， the drugs involved RIM were spironolactone （82.56%）， rivaroxaban （13.95%） and gabapentin （3.49%）. After reaching the balance between groups using the propensity score matching method， the incidence of frailty was 77.94% in trial group and 27.94% in control group （P＜0.001）； the difference was not statistically significant in other confounding factors between the two groups （P＞0.05）. Results of Logistic regression analysis showed that the risk of frailty in the experimental group was 3.118 times that of the control group （odds ratio was 3.118，95% confidence interval was 1.758-5.530， P＜0.001）. CONCLUSIONS RIM is a risk factor for the frailty of elderly patients with diabetes， which can be considered as an indicator for early identification and screening of the frailty of elderly diabetes patients.
