1.Currrent study of breast cancer stem cells
Journal of International Oncology 2010;37(5):368-371
The breast cancer stem cells are a subpopulatiom of breast tumor cells that selectively possess tumor initiation and self-renewal capacity. Recent findings suggest that it may correlate with the failure treatment and relapse of breast cancer. The isolation of phenotypically distinct tumorigenic of breast cancers will find a way to elucidation of the pathways that account for their tumorigenic potential to cure the disease.

4.Application of anti-vascular endothelium growth factor in assisted surgery for proliferative diabetic retinopathy
Chinese Journal of Experimental Ophthalmology 2017;35(1):87-92
Proliferative diabetic retinopathy (PDR) is one of the serious ocular complications of patients with diabetes mellitus and also the leading cause of blindness.Pars plana vitrectomy (PPV) is an effective treatment for severe vitreous hemorrhage and PDR.The intraocular concentration of vascular endothelial growth factor (VEGF) of patients with PDR usually increase abnormally,which promote growth of neovessels and make it early to leak and bleed.Numerous neovessels in vitreous cavity and retinal surface can lead to intraoperative bleeding and may affect the definition and precision of operation and prolong surgical time.If we conduct gas/fluid exchange regardless of severe active bleeding,proliferate membrane may reoccur at a high rate postoperatively due to the residual platelet and impair the success rate of surgery seriously.In addition,with the high activity of neovessels,anterior chamber,vitreous and retinal hemorrhage may appear as well as other postoperative complications like postoperative high intraocular pressure caused by inflammation or hemorrhage and traction retinal detachment because of reoccurrence of fibro membrane,which directly affect the postoperative visual function recovery and long-term prognosis.As wide clinical application of anti-VEGF agents in recent years,studies found that preoperative intravitreal injection of anti-VEGF drugs assisted PPV can limit the activity of neovessels and significantly reduce the incidence of intraoperative and postoperative bleeding,facilitate operation,shorten surgical time and improve the success rate of surgery.In this paper,the mechanism,effectiveness,clinical utility and safety of anti-VEGF therapy assisted vitrectomy for the treatment of PDR are reviewed.

Chinese Journal of Biochemical Pharmaceutics 2017;37(9):266-268
Objective To investigate the efficacy of rabeprazole combined with mosapride in the treatment of reflux esophagitis. Methods A total of 92 patients with reflux esophagitis admitted from April 2016 to April 2017 in our hospital were divided into study group and routine group (n = 46). The routine group was treated with omeprazole and Mosapride,the study group was treated with rabeprazole and mosapride. The clinical efficacy and adverse reactions in the two groups were observed and compared. Results The total effective rate was 91.30% in the study group and 76.09% in the conventional group, the difference was statistically significant (P<0.05). The total effective rate of reflux symptoms, esophageal irritation and esophageal irritation was significantly higher in the study group than in the conventional group (P<0.05)The adverse reaction rate was 4.35% in the study group and 6.52% in the conventional group, the difference was not statistically significant (P<0.05). Conclusion In the course of clinical treatment of reflux esophagitis, attention should be paid to the two aspects of acid suppression and gastric motility. In the inhibition of acid, the effect of Bella is obviously higher than that of omeprazole. In gastric motility, mosapride in clinical effect is better. Reflux esophagitis by rabeprazole combined with mosapride treatment, clinical efficacy is significant, and adverse reaction rate is low, safe and reliable, worthy of clinical application.
