Coronary heart disease is a kind of heart disease that is caused by atherosclerosis. The lipid deposition in the vessel wall results in occlusion of coronary artery and stenosis, which could induce myocardial ischemia and oxygen deficiency. Intervention therapies like percutaneous coronary intervention (PCI) and coronary stent improve myocardial perfusion using catheter angioplasty to reduce stenosis and occlusion of coronary artery lumen. Accordingly, intervention therapies are widely applied in clinic to treat ischemic cardiovascular disease, arterial intima hyperplasia and other heart diseases, which could save the patients' life rapidly and effectively. However, these interventions also damage the original endothelium, promote acute and subacute thrombosis and intimal hyperplasia, and thus induce in-stent restenosis (ISR) eventually. Studies indicated that the rapid reendothelialization of damaged section determined postoperative effects. In this review, reendothelialization of implants after intervention therapy is discussed, including the resource of cells contributed on injured artery, the influences of implanted stents on hemodynamic, and the effects of damaged degree on reendothelialization.

Objective:To investigate the in vitro inhibitory effect of methylene blue mediated photodynamic therapy (PDT) combined with berberine on Porphyromonas gingivalis (P.g). Methods:P.g was cultured until the middle to late log phase, and methylene blue was added to P.g suspension at different mass concentrations for 5 min, and a laser (wavelength 660 nm, power 140 mW/cm 2) was irradiated for 2 min to find the optimal concentration of methylene blue combined with the laser for in vitro inhibition of P.g. The effect of methylene blue mediated PDT on the in vitro inhibition of P.g and the effect of berberine on the growth curve of P.g were observed. The inhibitory effect of methylene blue mediated PDT and berberine on P.g was investigated by successive combined applications. The effect of methylene blue mediated PDT on P.g morphology was observed by scanning electron microscopy. The absorption peaks of each component were measured by ultraviolet spectrophotometer. Results:The best inhibition was achieved at a methylene blue mass concentration of 24.414 1 μg/ml under 660 nm laser excitation. The differences were statistically significant in both the methylene blue and PDT groups compared with the control group (all P<0.001). 0.05 mg/ml berberine had an inhibitory effect on the planktonic bacteria of P.g. After P.g was treated with methylene blue mediated PDT, the bacterial cell walls were crumpled into clusters. Compared with the control group, the number of colonies was reduced in the 0.05 mg/ml berberine group, and the difference was statistically significant ( P<0.01). The difference between the 0.05 mg/ml berberine + light group and the control group was not statistically significant ( P>0.05). When PDT was combined with berberine, there was a synergistic inhibitory effect on P.g. PDT followed by berberine shows a better inhibitory effect on bacteria, and the differences were statistically significant (all P<0.01). After the berberine treatment, the bacterial surface became smooth, and the length of the bacterial body increased compared with the control group. Conclusions:Methylene blue mediated PDT has an inhibitory effect on P.g. When combined with berberine, it has a synergistic inhibitory effect on P.g., and the inhibition effect is better when PDT is applied first and then berberine is applied in combination.

PURPOSE: Although it is widely accepted that hormone receptor (HR) status is associated with later post-diagnostic periods, a debate exists as to whether the association is independent of age. The aim of our study was to confirm the impact of HR status on later period breast cancer-specific death (LP-BCSD) and later period non-breast cancer-specific death (LP-non-BCSD) in different age subgroups. METHODS: Surveillance, Epidemiology, and End Results databases were utilized to identify 181,108 breast cancer patients with > 5 years survival. The cumulative incidence of LP-BCSD and LP-non-BCSD was calculated using the Gray method. The subdistribution hazard ratio (SHR) of variables was estimated via the Fine and Gray proportional hazard regression model. Subgroup analyses for LP-BCSD and LP-non-BCSD were performed according to the HR status. RESULTS: The risk of LP-BCSD was exceeded by that of LP-non-BCSD at > 5 years since the diagnosis, particularly in old women. The competing risk regression model indicated that hormone receptor-positive (HR+) was an independent factor for more LP-BCSD (hazard ratio, 1.54; 95% confidence interval, 1.44–1.54; p < 0.001). However, stratified analysis indicated that HR+ was only associated with more LP-BCSD in the young women subgroup. Although HR+ was associated with more LP-non-BCSD, the predictive value of HR+ for LP-non-BCSD was eliminated after adjusting for age. CONCLUSIONS: HR+ was related to LP-BCSD in the premenopausal population. LP-BCSD should be an optimal endpoint in future trials designed to evaluate the role of extended adjuvant endocrine therapy.
