PAX6 gene plays an important role in embryological development, and the mutation of this gene may result incongenital aniridia, retinoblastoma, macula hypoplasia, Peters' anomaly and so on. A brief introduction of the background PAX6 gene, and the association between PAX6 and retinal diseases were summarized in this review.

AIM:To evaluate the efficacy of treating traumatic optic neuropathy( TON) with mouse nerve growth factor.
METHODS: We searched the Cochrane Library, Pubmed, Medline, CNKI, Wanfang database and VIP to collect randomized controlled trials ( RCTs ) of using mouse nerve growth factor for TON. The quality of the included trials was assessed and poor-qualified trials were eliminated before the meta - analysis was conducted.
RESULTS:Seven RCTs with a total of 399 eyes included were retrieved, and OR=3. 78 with a 95%CI of [ 2. 35, 6.06], the difference was significant (P<0. 01).
CONCLUSION:The existing evidence supports that the prognosis of TON is better when mouse nerve growth factor are adopted in treatment, but there is still a need for well-planned, large-scale and multicenter RCTs to verify it.

BACKGROUND:Nowadays, most of the studies regarding tissue engineering bone have mostly focused on critical-size bone defects of the backbone; however, there are less studies and reports on its spinal fusion. OBJECTIVE:To explore the feasibility of xenogeneic deproteinized cancelous bone as bone tissue engineering scaffold in the treatment of spinal intertransverse fusion. METHODS:The cancelous part in the distal femur of adult pigs was obtained to prepare xenogeneic deproteinized cancelous bone. After combined with the recombinant human bone morphogenetic protein, the xenogeneic deproteinized cancelous bone was combined with bone marrow mesenchymal stem cels to prepare tissue engineering bone. Twenty-four goats were obtained to prepare intertransverse bone bed, and randomly divided into two groups: observation and control groups. In the observation group, the tissue engineered bone was implanted into the left side, and the xenogeneic deproteinized cancelous bone of recombinant human bone morphogenetic protein was implanted into the right side. In the control group, the autologous iliac bone was implanted into the left side, and xenogenic deproteinization cancelous bone was implanted into the right side. At the 4th, 8th and 12th weeks after implantation, the fusion segment was obtained for gross observation, X-ray observation, histological observation and biomechanical testing. RESULTS AND CONCLUSION:X-ray films showed that the implant materials from these two groups were fixed wel and reliably. At different time points after implantation, the implant materials from each group were al in good position. There were no purulent and necrotic tissues around the material. Soft tissue ingrow and wraping were present. There were no effusions and necrosis surrounding the implant materials. The imaging and histological performance in the tissue engineering bone group outperformed that in the recombinant human bone morphogenetic protein xenogenic deproteinized cancelous bone group and xenogenic deproteinized cancelous bone group, which was the most close to the autogenous bone. At the 12th week after implantation, the maximum bending load in the tissue engineering bone group was the most close to the autogenous iliac bone group. There was no significant difference between these two groups. These results demonstrate that as bone tissue engineering scaffold, xenogenic deproteinized cancelous bone has a certain application feasibility in the treatment of spinal intertransverse fusion.

In anesthetic clinical teaching,Dalian Medical University Department of Anesthesiology pays more attention to humanity education and keeps improving teaching methods.It also adopts the methods of “the combination of the virtual and reality”,multiple apprentices,PBL and other ways to enhance students' operational skills development and promote their clinical thinking.

?Ocular trauma related glaucoma is one of secondary glaucoma, which can lead to serious visual loss. According to the complex clinical findings and pathogenesis of ocular trauma related glaucoma, we divide traumatic secondary glaucoma into hyphema related glaucoma, angle recession related, lens injury related, adhesion and proliferation related. The treatment of secondary traumatic glaucoma with ocular trauma were different, specific treatment measures should be given according to the specific case to protect visual function.

Abstract?AlM: To observe the clinical efficacy and safety of glaucoma filtration surgery combined with the application of 5 - fluorouracil for clinical treatment to offer the reference.?METHODS:A total of 91 cases of patients with glaucoma treated in our hospital were randomly divided into three groups, 30 cases of group A were given mitomycin in surgery, 31 cases of group B were given 5-fluorouracil, 30 cases of group C were given cyclosporine. They were given 12 -month-follow-up after operation, the operation success rate were recorded, the incidence of 1 -year-adverse reactions, visual acuity, intraocular pressure, low intraocular pressure, shallow anterior chamber, corneal damage index were recorded.?RESULTS: lntraocular pressure ofgroups A, B, C were respectively (20.5±8.6)mmHg,(15.2±5.5)mmHg,(20.0± 8. 1 ) mmHg, by the analysis of variance, group B was significantly lower than other two groups,P<0. 05;patients of groups A, B, C whose visual acuity increased ratios after 1y were respectively 22. 5%, 38. 1%,and 23. 1% , by the Chi. square test, the increased ratio of group B was higher than other two groups , P<0. 05; The operation success rates after 1y of operation of groups A, B, C were respectively 67. 5%,88. 1%,71. 8%,by the Chi square test, the increased ratio of group B was higher than other two groups, P<0. 05;The general incidence of adverse reaction were respectively 22. 5%,9. 5%,20. 5%,by the Chi square test , the increased ratio of group B was lower than other two groups, P<0. 05.?CONCLUSlON:Glaucoma filtration surgery combined with the application of 5-fluorouracil can improve the operation success rate, decrease the occurrence rate of adverse reaction, and safety can be improved.

Objective To establish rat models with Alzheimer's disease(AD) induced by ?-amyloid,and to observe the effects of nicotine on learning and memorizing ability of the rats. Methods Aggregated A?1-40 was injected into the bilateral basal forebrain of the rats.Learning and memorizing ability of the rats were inspected through Morris water maze test.The effects of nicotine on learning and memorizing ability of the rats induced by ?-amyloid peptide were observed.

Objective To observe the expression of zinc finger protein A20(A20), NF-κB and related inflammatory factors before and after lipopolysaccharide (LPS) stimulates degeneration of rabbit intervertebral disc nucleus pulposus cells.Methods The normal and degenerative nucleus pulposus cells were isolated and cultured, then divided into normal group,degenerative group,LPS stimulation group and NF-κB inhibition group.HE staining observe the morphological changes of nucleus pulposus and annulus fibrosus,immunohistochemistry was used to detect the expression of A20,NF-κB/p65 and COL-Ⅱ.Real-time PCR was employed to analyze the expression of A20,IL-1β,TNF-α,NF-κB and COL-Ⅱ,Western blot was used to observe the A20 protein,p65 and COL-Ⅱexpression in the four groups, and TNF-α, IL-1β in cell supernatant was determined by ELISA.Results The number of nucleuspulposus cells significantly decreased, aggregation occured in the degenerative group.COL-Ⅱ was obvious lower and A20, p65 significantly higher than that in normal group by immunohistochemical staining.Compared with the normal group,A20,TNF-α,IL-1β,p65 expression was significantly increased and COL-Ⅱ decreased in the mRNA and protein levels in degenerative group.Above indexes changed more significant in LPS stimulation group than in degenerative group.The expression of A20, TNF-α, IL-1β, p65 in the NF-κB inhibitor group was lower than that in the LPS group, and the expression of type Ⅱ collagen increased(P<0.05).Conclusions Intervertebral disc inflammatory response is closely related to the development of intervertebral disc degeneration, A20 may play an important role.
