Lysine specific demethylase 1( LSD1) is a kind of flavin adenine dinucleotid ( FAD) dependent amine oxidase and can specifically demethylate H 3K4me2/me1 and H3K9me2/mel, thus it can regulate gene transcriptional activity .LSD1 is essential for mammalian development and is involved in many biological proces-ses,including cell differentiation,gene activation,and gene repression.Nowadays,it is demonstrated that LSD1 might promote cell phase transition(deficiency in LSD1 leads to partial cell cycle arrest in G2/M)and cell prolif-eration,suggesting that the over -expression of LSD1 might promote tumorigenesis.LSD1,as a demethylase,may be a new target for anti -cancer therapy.Hereby,we review on the structure,action mode of LSD1 and its rela-tionship with oncogenesis .

The introduction of research study in the course of biochemical engineering is discussed in the essay both in theory teaching and practice period to cuhivate the students'ability of self-development and innovation

Objective To study the change and its application of the brain stem auditory evoked potentials (BAEP) in language -impaired children. Methods We used evoked potentials Denmark Wedy Keypoint device to analysis the BAEP test results of the 79 cases of children in our hospital from August 2006 to December 2008. Rsults The total rate of BAEP abnormalities in children was 64.6% , of which 15.7% for one of the bilateral BAEP wave disappeared, 11.8% for the unilateral BAEP wave disappeared with the other side of the wave being abnormal BAEP,and 72.5% for the wave latency (PL) and wave interphase (IPL) abnomal. Conclusion BAEP is a sim-ple, noninvasive, threshold stability, results reliable and reproducible method of examination. For language -impaired children of hearing damage and abnormal neural pathway ,it can provide valuable objective indicators.

Objective To study the application value of laparoscopic uterine artery occlusion and uterine myomectomy for uterine myo-mas. Methods The data of 80 patients with uterine myomas in our hospital from January 2011 to January 2015 were studied. They were ran-domly divided into control group and observation group,40 cases in each group. The patients in control group received the laparoscopic myo-mectomy and the patients in observation group were treated by uterine artery occlusion and myomectomy. The hospitalization time,blood loss, disease incidence and recurrence between two groups were compared and analyzed. Results There was no statistically significance in aver-age operative time between two groups(P>0. 05). The exhaust time and hospital stay time in observation group were significantly shorter than those in the control group,the difference were statistically significant(P<0. 05). The blood loss in the control group(145. 2 ± 35. 5) mL was significantly higher than that of observation group(50. 8 ± 21. 6) mL,the difference were statistically significant(χ2 =14. 367 5,P=0. 000 0). The improved rate of postoperative menorrhagia in observation group was 100%, the control group was 25%,the differences were statistically significant(χ2 =4. 599 6,P=0. 032 0). There was no postoperative morbidity and recurrence in observation group. The postoperative morbidi-ty and recurrence rate in the control group were 5 cases (12. 50%) and 11 cases (27. 50%) respectively,the differences between two groups were statistically significant(P<0. 05). Conclusion Laparoscopic uterine artery occlusion combined with uterine myomectomy can reduce blood loss,shorten hospital stay time,reduce postoperative complication and recurrence of uterine myomas.

OBJECTIVE:To discuss about the development strategy of pharmaceutical enterprises in our country in the new century.METHODS:To expound the developing strategy that domestic pharmaceutical enterprises should adopt in respect to technical innovation,development of product,exploitation of market,human capital and enterprise culture.RESULTS & CONCLUSION:Facing the new management environment,the pharmaceutical enterprises in our country should achieve new breakthrough in development strategy to adapt to trend of the times,grasp opportunity and face challenge.

As an inevitable outcome of industrialization and modernization,fashion has already underlined and comprised our daily life.No matter it is fashion of substances,concepts or behaviors,all of them are crashing against the traditional ethics value system.Its unique characteristic tries to overthrow the traditional behavior mode and cognition mode,reflecting individual's abnormal sense of value.Fashion is a two-blade sword.On the one hand,it brings both society and individuals with positive ethical effect.On the other hand,it also leads to the popularity of consumerism,corroding people's spiritual world.Morality can be used as a guide and model of fashion,and fashion can also be used for decorating morality.To avoid dull preaches is the key to balance the mutual relationship between morality and fashion.

AIM:To compare and analyze the effect of recombinant bovine basic fibroblast growth factor ( bFGF ) eye drops and hydroxyl indican eye drops on the tear film stability and dry eye symptoms after age-related cataract surgery. ·METHODS: A total of 115 patients ( 115 affected eyes ) with dry eyes after age-related cataract surgery were divided into the bFGF group, the hydroxyl indican group and the blank control group by the random number table method. The blank control group was only given routine anti-inflammatory treatment, and on the basis, the bFGF group and the hydroxyl indican group were treated with bFGF eye drops and hydroxyl indican eye drops respectively. The clinical efficacy, adverse reactions, changes in scores of dry eye symptoms, Schirmer test ( SⅠt) , tear film break- up time ( BUT ) and corneal fluorescein staining ( CFS) scores at different time points were compared among the three groups. ·RESULTS:The total markedly effective rates in the bFGF group ( 89. 5%) was higher than that in the hydroxyl indican group ( 70. 3%) or the blank control group (47. 5%) (P<0. 05). Scores of dry eye symptoms, CFS, SⅠt and BUT in the three groups at 2 and 5wk after surgery were significantly different (P<0. 05). The above-mentioned indexes in the bFGF group at 2 and 5wk after surgery were significantly better than those in the hydroxyl indican group and the blank control group, and better in the hydroxyl indican group than the blank control group ( P < 0. 05 ). There were no obvious adverse reactions. ·CONCLUSION: The tear film is unstable in early stage after age-related cataract surgery, and there are dry eye symptoms. The intervention with bFGF eye drops and hydroxyl indican eye drops can effectively restore the tear film stability and significantly relieve dry eye symptoms, and the effect of bFGF eye drops is more significant.

Myopia is the most common human eye disorder in the world.Severe or high-grade myopia is a leading cause of blindness.We summarize genetic and environmental factors involved in the development of myopia.Multiple high-grade myopia genetic loci have been identified,but the exact pathogenesis of myopia remains unclear.Most myopia is caused by vitreous axial elongation,refracting to the light focus on the front of retina.The development of myopia is controled by two mechanism including high central and local in the eye.In this paper we focus on the genetic,cellular and molecular mechanisms in the development of myopia.
