Background Erythropoietin (EPO) was proved to be express in hematopoietic tissue and nervous system and play the effects of stimulating blood cell production and protecting nervous tissue.Researches showed that EPO is expressed in the embryon brain of animal.However,whether EPO exist in nervous-derived retina and its action on retina with the development is concerned. Objective This research was to investigate the expression of EPO during the embryonic development period of rat retina and explore the role of EPO in retina development process.Methods Clean Wistar rats with pregnancy for 12 days,16 days and 20 days were collected,and the embryonic 12-day rats (E12 d,5 rats),embryonic 16-day rats (E16 d,5 rats) and embryonic 20-day rats ( E20 d,5 rats) were obtained by caesarean operation,and 5 12-month W istar rats were used as controls.The rats were sacrificed by cervical dislocation and the retinal sections were prepared in the different-embryo-phase (12 d,16 d,20d) and growth phase.The expression of EPO protein and mRNA in rat retina was detected by immunohistochemistry and reverse transcription-polymerase chain reaction (RT-PCR),respectively.The feed and use of the animals followed the Regulation for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results EPO was positively expressed in the cytoplasm and nuclei in the neuroepithelial layer and pigment epithelium of every-embryo-phase rats but only in retinal ganglion cell layer in 12-month-old rats.The gray scale values of EPO expression in retina were 105.55±10.35,99.35± 8.71,83.27± 7.84and 30.30± 3.80 in E12 d rats,E16 d rats,E20 d rats and 12-month-old rats respectively with a statistically significant difference (F=76.13,P<0.01 ).RT-PCR revealed that the relative values of EPO mRNA expression in retina were 0.876±0.10,0.861 ±0.09 and 0.256±0.03 in E16 d rats,E20 d rats and 12-month-old rats respectively,presenting a elevated value in embryonic rats compared with adult rats ( P =0.00).Gel imaging deletion showed that the A value of EPO amplification products was highest in E16 d rats and lowest in adult rats.Conclusions The expression of EPO appears a high to low fashion during the embryonic development of Wistar rats,which is closely associated with the developing procedure of retina.

Contrary to being an idle bystander,the surrounding tumor microenvironment or stroma,actively participates in,and contributes to tumor progression directly or indirectly.It is evident that tumor stromal cells exhibit specific tumor-suppressive and tumor-promoting abilities that serve to regulate neoplastic growth of the epithelium.Due to the mounting evidence demonstrating the far-reaching effects of stroma during the process of malignant transformation,the involvement of stroma in cancer progression has become an area of intense investigations in recent years.

AIM: To compare the effectiveness of botulinus toxin of type A and complete resection of the periorbital muscle on idiopathic blepharospasm.
● METHODS: Patients with idiopathic blepharospasm and having undergone either of two procedures from Dec. 2010 to Jun. 2015 were selected ( 60 patients ) . Among them, group A (30 patients, 60 eyes) underwent botulinus toxin of type A, group B (30 patients, 60 eyes) underwent complete resection of the periorbital muscle.
●RESULTS: ln group A, the patients with complete response, obvious response, partial response, and no response were 36(60. 0%), 20(33. 3%), 2(3. 3%) and 2 (3. 3%) cases respectively. ln group B, the patients with complete response, obvious response, partial response, and no response were 16(26. 7%), 24(40. 0), 12(20. 0%) and 8 ( 13. 3%) cases respectively. The difference was statistically significant ( Z = - 2. 968, P = 0. 003 ). The relapse rate of group A and group B were 93. 3% and 20. 0% after 6mo, the difference was statistically significant (χ2=32. 851, P<0. 001).
●CONCLUSION: The botulinus toxin injection of type A is effective for idiopathic blepharospasm. But recurrence rate is high after 6mo. Complete resection of the periorbital muscle have long-term efficacy for idiopathic blepharospasm. It′s a supplementary therapy after idiopathic blepharospasm recurrence.

To control the quality of Humulus scandens, the quality standard was established in this study. According to the method recorded in the Appendix of Chinese Pharmacopoeia (2010 Edition) , the water and ash inspections were carried out. The component luteoloside and cosmosiin in Humulus scandens were identified and assayed by TLC and HPLC. The results showed a strong characteristics microscopic of Humulus scandens, and trichoromethane-methanol-formic acid (10: 3: 0. 3) as the mobile phase of TLC, the spots at 365 nm with a UV lamp was clear. The 16 batches of samples were analyzed by HPLC with a gradient elution of acetonitrile and phosphate solution (0.2%) at a flow rate of 1.0 mL · min(-1) and detected at 350 nm. The content of luteoloside was 0.015%- 0.651% (average 0.148%); the content of cosmosiin was 0.003%-0.118% (average 0.036%). The linear calibration curve of luteoloside and cosmosiin was acquired in the ranges of 0.011-0.364 g · L(-1) (r = 1.000 0) and 0.003-0.096 g · L(-1) (r = 1.000 0), respectively. The average recovery was 100.5% and 98.5%, respectively. The methods are convenient and reliable, which can be ap- plied for quality assessment of Humulus scandens.
