BACKGROUND:Retinal diseases are caused by damage or apoptosis of the retinal cel s and lack of ideal treatment. Induced pluripotent stem cel s have self-renewal ability and differentiation potential. A new potential source from which to produce stem cel s as a therapeutic platform for the treatment of retinal diseases and avoid ethics issues is the research focus currently.
OBJECTIVE:To review recent advancement of induced pluripotent stem cel s and the potential utility for retinal diseases.
METHODS:The first author searched related articles published from 2006 to 2011 by computer retrieval in PubMed database using the keywords of“induced pluripotent stem cel s, retinal, photoreceptor, retinal pigment epithelium, retinal ganglion cel”in English. Final y, total y 42 papers were involved.
RESULTS AND CONCLUSION:Induced pluripotent stem cel s can be induced to differentiate into retinal cel s which have a possibility to be used as donor cel s for transplantation therapies. Patient-derived induced pluripotent stem cel s can be used as disease models for mechanistic studies and drug screening. It is a promising therapy for retinal degenerative diseases. However, some problems stil remain, such as risk of teratoma formation and low efficiency of somatic cel s to be successful y induced into induced pluripotent stem cel s. It stil requires further more studies.

Objective To investigate the changes of lymphocyte subsets before and after the treatment with operation and chemotherapy in patients with breast cancer.Methods Using cytometer to measure lymphocyte subsets of CD3+,CD4+, CD8+,CD4+/CD8+ and NK of 25 breast cancer patients before and after treatment.The all 25 patients were treated with operation and chemotherapy after pathological diagnosis.The article compared the figures of T cell subsets before and after treatment.Results Compared with before operation and chemotherapy,the CD8+ statistically decreased after 1~3 months of treatment (t=2.57),and NK statistically increased after 3~6 (t=-2.23).After 6 months of treatment,the patients’ CD3+(t=-2.25),CD4+(t=-2.07)were statistically lower and NK (t=-3.56)was statistically higher.There was no significant difference for other items.Conclusion Lymphocyte subsets test against breast cancer patients can reflect immuni-ty level at a certain level during treatment.But how to explain the figures in different stage against treatment effectiveness and prognosis need further research.

Objective To investigate the distribution and antimicrobial resistance of gram-negative bacilli isolated from wound specimens of orthopedic patients,and provide reference for the rational use of antimicrobial agents. Methods 682 isolates of gram-negative bacilli were collected from orthopedic department in a comprehensive hospi-tal between January 2011 and December 2013, antimicrobial susceptibility testing results were analyzed. Results The main gram-negative bacilli isolated from wound specimens of orthopedic patients were Pseudomonas aeruginosa (P .aeruginosa)(16.72%),Escherichia coli (E.coli)(15.40%),and Enterobacter cloacae (E.cloa-cae)(12.76%).The detection rates of extended-spectrum beta-lactamase-producing E.coli and Klebsialla pneu-moniae (K .pneumoniae)were 54.29%(57/105)and 31 .43% (22/70)respectively,and mainly distributed in the trauma orthopedic department,accounting for 49.12% and 45.45% respectively.The susceptibility rates of E.coli, K .pneumoniae ,and E.cloacae to meropenem and imipenem were all 100.00%.The susceptibility rates of E.coli and K .pneumoniae to amikacin,piperacillin-tazobactam and amoxicillin/clavulanic acid were all >80%.Suscepti-bility rate of E.cloacae to most antimicrobial agents were 71 .26% -100.00% except for piperacillin(64.37%). Susceptibility rates of P .aeruginosa to most antimicrobial agents were >85% except for cefepime (78.95%)and aztreonam (65.79%).Conclusion Gram-negative bacilli are the most common pathogens in wound infection of or-thopedics patients.In order to use antimicrobial agents rationally and improve clinical treatment effect,it is impor-tant to realize the distribution of pathogens and antimicrobial resistance.

The transesterification reaction conditions of lard with methyl acetate with combined use of immobilized lipases as catalysts were conducted. Initially, according to single factorial experiments, the studies on Lipozyme TL IM and Novozym 435 respectively catalyzed transesterification of lard showed that the optimal parameters of transesterification reaction were: the molar ratio of methyl acetate to oil of 14∶1, 40% enzyme added based on oil weight, temperature 50℃. Combined use of Lipozyme TL IM and Novozym 435 was proposed further to improve the catalytic performance by the response surface method (RSM). Herein, a 5-level-3-factor central composite rotated design was employed to evaluate the effects of lipase loading, the proportion of the two lipases and amount of methyl acetate. The optimum conditions were as followings: 40% lipase loading based on oil weight, 50%/50% the proportion of lipases (Novozym 435/Lipozyme TL IM), and the molar ratio of methyl acetate to oil of 14∶1. And under the optimal conditions, the highest biodiesel yield of 97.6% could be attained, which was higher than the biodiesel yield with each single one of the two lipases. The results suggested that the technics of combined use of certain immobilized lipases catalyzed transesterification reaction of lard for biodiesel production with methyl acetate as the acyl acceptor could raise the FAME yield and save the production cost.

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.
