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.

Phyllosphere and epiphytes have attracted significant interest of more and more researchers by their unique biological characteristics. Progress of research on phyllosphere and epiphytes was summarized in this paper, and the special emphasis was put on the characteristic of phyllosphere, microbial communities, invasion and the location of bacteria on leaf surfaces. Some ideas for further studies on phyllosphere microbes were also proposed.

Objective To explore the different characteristics of tumor recurrence after liver transplantation (LT)and hepatectomy(HC)in patients with hepatocellular carcinoma(HCC).Methods The literatures about tumor recurrence of HCC after LT and HC were reviewed and their characteristics were compared.Results There are distinctions of recurrence rates,time,common sites between the recurred tumors after LT and HC,and their correlation factors and mechanisms of recurrence are also different.Conclusion Preventive measures should be strengthened and treatments should be more targeted according to the different characteristics of tumor recurrence after LT and HC to improve postoperative life quality and increase the survival rate.

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.

Objective To investigate the technique of b iliary reconstruction and treatment of biliary complications in orthotopic liver transplantation (OLT). Methods From Feb. 1999 to Jan. 2003, OLT was performed in 103 patients with end-stage l iver disease. OLT was performed with standard techniques with or without a veno -venous bypass. Reconstructions of biliary tract were performed using choledoc hocholedochostomy (CDC) or Roux-en-Y choledochoje- junostomy (RCDJ). CDC was carried out in 94 cases, with T tube (CDCT) in 62 cases and without T tube (CDCO ) in 32 cases respectively. Among the 32 cases without T tube, 11 had a small tu be placed in the common bile duct through the recipient cystic duct. RCDJ was pe rformed in 9 cases without internal stent. Diagnosis of the biliary complication s after OLT was based on the clinical manifestations, ultrasound findings, MRCP and ERCP. All the patients were followed up regularly after discharge for 12 to 48 months. Results The overall incidence of biliary complications in 103 patients after OLT was 7 .8% (8/103). Of the 62 cases of CDCT posttransplant, biliary complications occ urred in 6 cases ( 9.6% ), including 4 cases of bile leaks following OLT and 2 cases of bile leaks following T-tube removed. Of the 32 patients subject to CD CO, 1 ( 3.1% ) had stricture of anastomosis. Of the 9 cases subject to RCDJ, one patient was complicated with bile leaks at the anasto mosis. Two cases of the bile leaks were drained reoperatively, and others were k ept adequate drained. The patient with stricture of CDCO was cured by balloon di latation and stent placed endoscopically. No death associated with biliary compl ications occurred. Conclusions Bile leaks and stricture of anatomosis are the common biliary complications afte r OLT. Good blood supply to biliary tract and surgical technique are the keys to prevent biliary complications after OLT. The timely endoscopical and radiologic al technique is a valuable nonoperative precedure for diagnosis and treatment of biliary complicat ions.

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.

AlM:To observe clinical effects between the laser in situ keratomileusis ( LASlK ) surgery and the laser subepithelial keratomileusis ( LASEK ) surgery as the second operation after an unsuccessful LASlK surgery.METHODS:Forty-nine patients (98 eyes) with refractive regression after LASlK operation received the second surgery. All patients were divided into two groups:group A and B. Group A (48 eyes of 24 patients) received LASlK surgery and group B ( 50 eyes of 25 patients ) received LASEK surgery. lnspect the main parameters included visual acuity, refraction, corneal curvature, and the total value of high-aberration after 1wk, 1mo and 1a, t-test of groups was used as statistical analysis method.RESULTS: There was statistically significant (P<0. 05) between the two groups in visual acuity after 1wk. There was no statistically significant between the two groups in visual acuity after 1mo, and there was also no statistically significant between the two groups in visual acuity, average spherical equivalent refractive degree, average corneal curvature, and the total value of high-aberration after one year (P>0. 05). There developed one case of epithelium in growth after LASlK surgery, and one case of haze Ⅱ after LASEK surgery.CONCLUSlON: Both LASlK and LASEK surgery can obtain satisfactory therapeutic results after an unsuccessful LASlK surgery.
