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 .

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.

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 evaluate the clinical value of plasma procalcitonin and D-dimer measurements in estima-ting the prognosis of patients with sepsis.Methods According to prognosis,68 patients with sepsis were divided in-to survival group and death group,levels of procalcitonin and D-dimer,and acute physiology and chronic health eval-uation II (APACHE II)of two groups of patients were compared,predictive value of above markers in estimating the prognosis of patients with sepsis were evaluated.Results Of 68 patients with sepsis,28 survived and 40 died, mortality was 58.82%.There were significant differences in levels of procalcitonin and D-dimer,as well as APACHE II between two groups(both P<0.05),death group were all higher than survival group.Procalcitonin and D-dimer level were positively correlated with APACHE II score(P<0.05).Conclusion Procalcitonin,D-dimer level and APACHE II score can be used to evaluate condition of patients with sepsis as well as the prognosis of dis-ease.

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.

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.

Objective:To investigate the clinical effect of Six Ingredient Rehmanuia Decoction variation and cortial hormone for autoimmune hepatitis. Methods: 60 patients with autoimmune hepatitis were divided into two groups: the treatment grouup(30 cases) and control group(30 cases). Both the treatment group and control group were given methyl prednisolone. The treatment group was treated with hormone with the additon of Six Ingredient Rehmanuia Decoction, etc., one packet a day. The treatment courses of two groups were all 8 weeks. Results: The treatment group was superior to the control group in symptom, liver function and improvement of immune function. Conclusion: Six Ingredient Rehmanuia Decoction and a small dose of cortical hormone is effective for autoimmune hepatitis. No side effect is observed.
