?Silent information regulator protein 1 ( SlRT1 ) is a kind of histone deacetylases class lll on which cell metabolism coenzyme NAD+ is dependent. By the transcriptional regulation, it participates in the regulation of gene transcription, energy metabolism and cell aging process, which can prolong the lifespan of organisms and delay the development of various age-related diseases and has attracted much attention in the field of anti - aging research. ln recent years, studies have shown that SlRT1 occupies an important position in the pathogenesis of many ophthalmic diseases, especially in ocular surface diseases, glaucoma, cataracts, uveitis, and ocular fundus diseases, etc. There is a possibility that the promotion of SlRT1 activity would be the new drug target of ophthalmic therapy. The paper will review studies on SlRT1 and ophthalmic diseases.

OBJECTIVETo study the applied value of double joystick technique in reduction-internal fixation for femoral shaft fracture in adults.

METHODSThirty-four patients (24 males and 10 females) with femoral shaft fractures were treated with reduction assisted by double joystick technique and internal fixation with interlocking intramedullary nail from September 2010 to June 2013. The average age of the patients was 41 years old, ranged from 17 to 65 years old. The duration of the disease course ranged from 3 to 7 days, with a mean of 5 days. The fractures belonged to AO types 32A (5 cases), 32B (20 cases) and 32C (9 cases) and located in left femur for 18 patients and right femur for 16 patients. The patients were followed up, and fracture healing and complications were observed. The curative effect were evaluated according to Thorsen femur fracture evaluation standard.

RESULTSThe operative time ranged from 40 to 110 min (mean 75 min) and intraoperative blood loss ranged from 200 to 300 ml (mean 250 ml). All the patients obtained a good fracture reduction and were followed up for 12 to 24 months (mean 18 months) after the surgery. All the fractures united between 4 and 8 months with a mean of 5 months. No complications such as breakage of nail, infection, osteofascial compartment syndrome, refracture and fracture malunion were found. According to Thorsen femur fracture evaluation standard, 30 patients obtained an excellent result, 3 good and 1 fair.

CONCLUSIONIn surgery of reduction-internal fixation for femoral shaft fracture in adults, the use of double joystick technique obtains good reduction result, short operative time, less injury, high healing rate of bone fractures, less complications and good limbs function, so it is worthy of popularizing in clinic.

Background Epipolis laser in situ keratomihusis(Epi-LASIK) is an potential surgery for myopia because it synthesize advantages of LASEK and LASIK. But its clinical effectiveness and safeness is remarkable.Objective This study was to evaluate the clinical curative effects and safeness of Epi-LASIK for myopia in different diopter of population. Methods Retrospective study was designed for 208 eyes of 104 patients who underwent EpiLASIK for the correction of myopia. The patients were divided into two groups according to preoperative diopter:lower myopia group( ≤ -6.00 D, 111 eyes) and high myopia group ( ＞-6.00 D,97 eyes). The time of epithelial healing, postoperative syndrome, postoperative visual acuity, refraction, intraocular pressure (IOP) , the safe index, the efficacy index and haze were evaluated at 1,3,6,12 months postoperatively. The written informed consent was obtained from each individual before surgery. Results After operation, 20 eyes ( 18.02% ) of lower myopia group and 29 eyes (29.90%) of high myopia group had obvious pain, presenting statistically significant difference between two groups (X2 = 4. 060, P＜0.05 ). The mean time of epithelial healing was (5.49±0. 83 )days in lower myopia group and (5.85± 0.68 )days in high myopia group with a delayed epithelial healing time in high myopia group( u= 3. 377 ,P＜0.05 ).One year after the treatment,the uncorrected visual acuity( UCVA ) ≥ 1. 0 was 90. 99% ( 101 eyes) in lower myopia group and 75.26% ( 73 eyes) in high myopia group, and 9.91% ( 11 eyes) and 15.46% ( 16 eyes) of the eyes improved byl line or more in best spectacle corrected visual acuity(BCVA) ;whereas 3.60% (4 eyes)and 6. 18% (6 eyes)lost a line or more. 91.89% ( 102 eyes) and 85.57% (83 eyes) in both groups gained within 1.00 D of the attempted correction. The safety index and efficacy index were 1.04 and 0. 98 in lower myopia group,and 1. 01 and 0. 96 in high myopia group without statistically significant difference( P＞0. 05 ). haze occurred in 6 eyes in lower myopia group and 9 eyes in high myopia group and the difference in haze grading was not statistically significant between two groups ( P＞0. 05 ). The high intraocular pressure appeared in 10 eyes and 9 eyes in low myopia group and high myopia group respectively during the fellow up duration and back to normal after topical use of timolol. Conclusion Epi-LASIK is an effective and safe method for correction of different diopters of myopia because of its mild symptom and lower incidence of haze.

BackgroundIt has been well-known that integrin linked kinase(ILK) plays an important role in the pathogenesis of neorascularization.But there are few researches to elucidate the relationship between ILK and retinal nevascularization. Objective This study was to explore the expression and significance of ILK on retinal neovascularization and new vessels regression in the oxygen-induced retinopathy(OIR) mouse model. Methods One hundred and twenty-eight 7-day-old C57BL/6J mice were randomly divided into the normal group and model group.The mice were rose in(75±2)％O2 environment with mother mice together for 5 days and then in normal environment for 5 days to establish the OIR models.The mice in normal group were rose in the normal environment for 21 days.The 17-day-old mice were sacrificed and retinal sections were prepared for histopathological examination and the numbers of the cellular nuclei of vascular endotheliumbreaking retinalinternal limiting membranewere calculated.Retinal sections and sheeting were prepared in 12,14,17 and 21 -day-old mice to examine the formation and regression of new blood vessel using ADP histochemistry staining,and then immunochemistry,real-time PCR and Western-blotting were used to detect the expressions of ILK and its mRNA in retina. ResultsThe numbers of the cellular nuclei of vascular endothelium breaking retinal internal limiting membrane were (45.64 ± 12.17 )in OIR group,and those of the normal group were( 0.35±0.14 )with a significant difference between two groups (t =22.85,P＜0.05).Retinal new blood vessel appeared in 14-day mice,and peaked in 17-day mice and then regression in 21-day mice.ILK protein was expressed mainly in retinal ganglion cell layer,inner nuclear layer,inner plexiform layer and photoreceptor layer.Real-time PCR showed that ILK mRNA expressing levels in retina in model group were( 1.00±0.22),(1.85±0.17),(1.58±0.43) and(1.53±0.36) respectively in 12-,14-,17- and 21-day mice.Westernblotting determined that the A value of the ILK/β-actin was increased in 12-,14-,17-day mice and decreased in 21-day mice,and the A values were significantly higher in model group than the control group in various aged mice ( t =2.97,P＜0.05 ;t =11.88,P＜0.01 ;t =16.84,P＜0.01 ;t =13.00,P＜0.01 ). ConclusionsThese results indicate a space-time corresponding relation between the expression of ILK and retinal neovascularization.The obvious positive expression of ILK may be highly correlated with retinal neovascularization.
