AIM: To evaluate the clinical effect and the rotational stability of AcrySof Toric intraocular lens ( IOL ) implantation to correct preexisting corneal astigmatism in cataract surgery.
METHODS: Twenty-three patients ( 28 eyes ) were enrolled from the department of ophthalmology in the first Affiliated Hospital of Nanjing Medical University. All patients underwent similar phacoemulsification procedure combined with AcrySof Toric IOL implantation from June 2012 to December 2013. The uncorrected visual acuity ( UCVA ) , best corrected visual acuity ( BCVA ) , anticipated residual astigmatism, postoperative residual astigmatism, and Toric IOL axis were detected and measured.
RESULTS:Three months after operation, the UCVA of all eyes were 0. 75±0. 16 and the BCVA were 0. 84±0. 15, there was no significant difference between UCVA and BCVA ( t = 1. 036, P>0. 05 ). The anticipated residual astigmatism was ( 0. 28±0. 12 ) D. The actual residual astigmatism after 3mo of the operation was (0. 42±0. 17) D. There was no significant difference between anticipated and actual residual astigmatism (t=1. 259, P>0. 05). The mean axis rotation of Toric IOL was 3. 02o±1.56o (0o-7o) after 1d of operation and 3. 28o±1. 85o (0o-7o) after 3mo. Among all the eyes, 25 eyes ( 89%) rotated <5o, in 3 eyes (11%) rotated 5o-7o.
CONCLUSION: The AcrySof Toric IOL implantation shows good effectiveness, predictability and stability in correcting pre-existing astigmatism in cataract patients.

Objective To study the survival,migration and differentiation of the neural stem cells which transplanted into ventral horn of spinal cord after brachial plexus avulsion.Methods Neural stem ceils isolated from spinal cord of neogenetic rats and cultured,expanded,labeled by BrdU before transplanted. Twenty adult healthy SD rats preformed as the model of brochial plexus avulsion(Roots C_(5~7)),then transplan- rod stem ceils into the C_6 ventral horn of spinal cord.On 1,2,4,8,12 weeks postoperatively,immunohisto- chemistry assay were carried out in the spinal cord.Results Transplanted into ventral horn of spinal cord after brachial plexus avulsion.Neural stem cells can survive,migrate for at least one segment of spinal cord and differentiate to neurons and astrocytes.The differentiation of stem cells were time-depends.Conclusion Neural stem cells can survive,migrate and differentiate after transplanted into ventral horn of spinal cord in the rats which suffered from brachial plexus avulsion.

AlM: To monitor long - term changes of matrix metalloproteinase-2 ( MMP-2 ) in human tears fluid after laser in situ keratomileusis ( LASlK) .
METHODS: Thirty - two myopia cases ( 64 eyes ) underwent uneventful LASlK were enrolled in the study. Tear fluid were collected and MMP-2 expression was analyzed by Western - bolt assay preoperatively and postoperatively on 15d, at 1, 3mo, and 1a.
RESULTS:LASlK increased the concentration of MMP-2 in human tear fluid. At 15d postoperatively, the magnitude of MMP-2 was 1. 4 times that of preoperative, thereafter subsided, but didn't return to preoperative level by 3mo ( P < 0. 05 ). Up to 1a after surgery, the concentration of MMP-2 almost recovered (P>0. 05).
CONCLUSlON: MMP- 2 is significantly expressed in human tear fluid after LASlK, then subsided with time, but didn't return to preoperative level by 3mo and almost recovered up to 1a, indicating wound healing of LASlK would continue up at least 3mo after surgery and almost recovered 1a postoperatively.

Objective To evaluate the performance of nested PCR in the detection of different fungi in paraffin wax embedded tissues. Methods Forty-four tissue samples were resected from rats infected with Fonsecaea monophora, patients with chromoblastomycosis, sporotrichosis or penicilliposis marneffei followed by preparation of paraffin wax embedded tissue sections for pathological examination and DNA extraction. Nested PCR was performed by using specific primers targeting the ribosomal DNA of Fonsecaea, Sporothrix and Penicillium marneffei, respectively. The sensitivity and specificity of nested PCR were analyzed and compared with those of pathological examination. Results The nested PCR showed positive results in 8 of 20 samples from rats with chromoblastomycosis, 7 of 10 samples from patients with sporotrichosis and all of the 10 samples from patients with penicilliposis marneffei, but not in the control samples. In the detection of Fonsecaea,Sporothrix schenki and Penicillium marneffei, the sensitivity was 40% ,70% and 100%, respectively, and the specificity was consistently 100%, for the nested PCR. Pathological examination revealed fungal elements in 95%, 70% and 80% of the corresponding samples, respectively. Conclusion Detection of fungal DNA in paraffin wax embedded tissue by nested PCR can be applied to the diagnosis of deep mycosis, especially to the diagnosis of penicilliposis marneffei.

Background Bevacizumab is primarily aimed at pathologic angiogenesis for off-label uses such as the treatment of ocular neovascular disorders.However,as a new anti-fibrotic and anti-angiogenic agent following trabeculectomy,the safety and efficacy of bevacizumab by multiple-time and high-dose subconjunctival injection are still under study.Objective This study was to assess the safety and efficacy of bevacizumab after multiple-time and high-dose subconjunctival injections.Methods Regular trabeculectomy filtration surgery was performed on both eyes of 18 clean New Zealand White rabbits 0.1ml of bevacizumab(25g/L) was subconjunctivally injected intraoperatively and 3,5,7 days postoperatively in the left eyes of rabbits,and no any intervene in the right eyes were as normal controls.Bleb morphology was examined every 2 days and graded based on Moorefield's criteria and compared between the bevacizumab-treated eyes and normal saline(NS) eyes.The animals were sacrificed at 10,20 and 30 days after surgery respectively.The histopathological changes of the blebs were detected by hematoxylin and eosin stain to evaluate the cellular element around the bleb,and Masson stain was used to assess the degree of fibroblast proliferation.The degree of vascularity of bleb was identified by anti-vWf stain.Approval of this protocol was obtained and permitted from People's Hospital Institutional Animal Care and Use Committee of Peking University.The use of experimental animals complied with the Regulation for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results Compared to the NS-treated eyes,bevacizumab-treated eyes showed the larger and more diffusely elevated blebs with the significant difference(2.48±0.22cm2 versus 1.73±0.27cm2,t=5.194,P<0.05).The survival time of the filtration bleb in bevacizumab panel was longer in bevacizumab-treated eyes compared to control eyes,showing a significantly difference between them(21.0±1.56 days versus 12.5±1.97 days,t=3.830,P=0.005).Histological and immunohistochemical analysis confirmed that bleb and adjacent conjunctiva vascularity(A value) was significantly less in bevacizumab-treated eyes than that in control eyes at 20 days after surgery with the difference value 14320.7±4134.9(t=12.275,P<0.05),and fibroblast deposition value was evidently diminished after bevacizumab treatment at 30 days following surgery in comparison with control eyes with the mean difference 0.27±0.03(t=15.980,P<0.05=.Conclusion Repeated subconjunctival injection of bevacizumab can effectively prolong the survival time of bleb in a rabbit model of trabeculectomy and limit the degree and area of vascularization in 30 days following surgery.Bevacizumab inhibit fibroblast-meditated tissue formation significantly in the later phase of vascularization after trabeculectomy.
