Background and purpose:Exposure to estrogen is an important independent determinant of the risk of breast cancer.Moreover,chemokines and its corresponding receptors play an important role in breast cancer occurrence and development.Our study is to investigate the impact and related mechanism of estrogen on chemokines expression in breast cancer cells.Methods:Microarray was performed to analyse chemokine and corresponding receptors' mRNA expression in MCF-7 cells treated with estradiol.Real-time(RT)-PCR was applied to confirm the change of chemokine expression at different time point with different dose of estradiol in presence or absence of ICI182,780.ELISA was used to analyse the change of extracelluar secrete protein.Results:Physiological estradiol could obviously up-regulate CXCL12 mRNA expression in breast cancer cell MCF-7,which emerged from 4h after treatment and continued to 24 h.In addition,estradiol could stimulate CXCL12 protein secretion from 2h to 24h after treatment.These effects could be totally inhibited when MCF-7 was treated with ICI182,780(ER antagonist)prior to estradiol.Conclusions:Our study demonstrated that estrogen could up-regulate CXCL12 mRNA expression and its extracelluar protein secretion,which was mediated through ER signaling pathway.

Objective To describe the initial experience of transperitoneal laparoscopic renal plication for giant hydronephrosis,and to evaluate the clinical feasibility of the procedure. Methods This series included 12 cases of giant hydronephrosis (5 men and 7 women;age ranged from 19 to 64 years with a mean of 42.6 years).Of them 4 cases had upper ureter calculi;2 had ureteropelvic junction(UPJ) obstruction;2,middle ureter calculi;3,nephrolithiasis and 1,middle ureter stricture. The upper urinary tract obstruction was relieved and plication was performed via laparoscope. Results All the 12 operations were completed successfully.The intraoperative blood loss was 50 to 200 ml,operative time was 75 to 210 min.The postoperative follow-up lasted 3 to 18 months.In all these cases,hydronephrosis was relieved and renal function was improved. Conclusions Laparoscopic renal plication is an effective and minimally invasive method and can be considered as an alternative for treatment of giant hydronephrosis.

Objective To investigate the effect of nerve growth factor (NGF) on recuperate of optic nerve after contusion by clamping in adult rabbits. Methods Sixteen adult rabbits were randomly divided into NGF and the control group with 8 rabbits in each group. After the optic nerve of the right eyes was clamped,tissue engineering nerve containing (0.06 ml) NGF(concentration: 5?10~(-4) g/L, NGF group) and 0.06 ml of PBS (control group) was immediately transplanted into the injured eyes respectively, and 0.02 ml NGF(concentration: 5?10~(-4) g/L, NGF group)and 0.02 ml of PBS (control group) were injected into the vitreous of right eyes respectively. Flash visual evoked potential (FVEP) test was performed on the eyes 1 day, 2 weeks and 8 weeks after the injury. The number of retinal ganglion cells (RGCs) and changes of optic nerves were observed by light microscopy and electron microscopy at the 8th week after contusion,and a computer-image-analysis system was used to count the optic nerve axons. Results The ratio of amplitude of FVEP of the injured and healthy eyes was 0.765?0.150 in NGF group and 0.494?0.108 in the control at the 2th week after injury with a significant difference between the two groups (P

Serum levels of macrophage migration inhibitory factor (MIF) were measured with enzyme linked immunosorbent assay (ELISA) in 60 patients with vitiligo vulgaris (case group) and 30 healthy individuals (control group).The case group was further divided into two subgroups:progressive stage (n =30) and stable stage (n =30).The association of MIF level with vitiligo area and severity index (VASI) score of disease was analyzed.The results showed that the serum MIF levels in patients with progressive stage were significantly higher than those in stable stage and in healthy controls (79.8 ± 38.0) μg/L vs.(48.4 ± 17.6) μg/L vs.(29.6 ± 22.1) μg/L,respectively,both P ＜ 0.001.Serum MIF levels were positively correlated with VASI scores of patients (r =0.48,P ＜0.001).The results indicate that MIF may be involved in the pathogenesis of vitiligo vulgaris.
