ABSTRACT
@#AIM: To observe the efficacy and safety of pars plana vitrectomy(PPV)combined with air tamponade in the treatment of rhegmatogenous retinal detachment(RRD), which caused by superior break(s)following previous vitreoretinal surgery.<p>METHODS: Retrospective analysis of the inpatients in our hospital from November 2017 to October 2019. Patients with RRD caused by superior break(s)who had underwent previous vitreoretinal surgeries and the proliferative vitreoretinopathy less than PVR-C1 were enrolled. For treatment, patients underwent PPV combined with air tamponade. During the operation, the residual vitreous cortex was fully removed, and the subretinal fluid was aspirated from retinal break(s)as much as possible. Make sure the subretinal fluid around the hole was fully drained. Then firmly laser spots were accomplished to seal the retinal break(s). Finally, filtered air was left in the vitreous cavity as tamponade agent. The patients were informed to keep a prone position for 24h postoperation. The primary outcomes were primary and final success rates, best corrected visual acuity(BCVA), and the secondary outcomes were rate of postoperative cataract surgery and high intraocular pressure.<p>RESULTS: Totally 31 patients(31 eyes)with follow-up time more than 6mo were included. The range of retinal detachment was 6.7±3.8h, and the number of retinal breaks was 1.2±0.7. There are 23 eyes(74%)with macular detachment and 18 eyes(58%)with intraocular lens. 6 eyes(19%)were treated with phacoemulsification and intraocular lens implantation together. The rate of primary retinal reattachment in enrolled patients was 87%(27/31), and the final reattachment rate was 100%(31/31). At the 6mo of postoperatively, the BCVA(LogMAR)increased from 2.17±1.27 to 0.53±0.25(<i>P</i><0.001). Furthermore, 5 eyes(16%)developed transient ocular hypertension.<p>CONCLUSION: PPV with air tamponade can achieve a high success reattachment rate in the management of RRD following previous vitreoretinal surgery. It has the advantages of short postoperative prone time and fewer complications.
ABSTRACT
Objective:To construct a management program of hand function rehabilitation for adult inpatients after hand burn. Methods:Literatures of clinical practice guideline, evidence summary, systematic review and review were searched from OVID JBI, Cochranel Library, EBSCO, PubMed、EMbase、FEBM, CNKI, Wanfang Data and CBM, and so on. They were screened, evaluated, extracted evidence, found hinder factors following the steps of Knowledge to Action (KTA). Finally, a hand function rehabilitation management program was constructed. Results:Ten literatures were included. The management program included hand function rehabilitation intervention program and implementation procedures. Conclusion:Based on KTA framework, the hand function rehabilitation management program after burn can be used in clinic.

ABSTRACT
Abstract?AIM: To assess the current situation of trachoma in Shaanxi Province and analyze its epidemiology and clinical features.?METHODS: The World Health Organization ( WHO ) simplified trachoma grading system was used for the recognition and registration of cases of trachoma. Trachoma rapid assessment ( TRA ) was conducted and 30.3687 million people from Shaanxi province were screened. Eyelids, eyelashes, conjunctiva and cornea were examined.The prevalence of trachoma trichiasis ( TT) in Shaanxi Province was estimated.?RESULTS: Totally 987 cases with TT were collected in Shaanxi province, in which 395 cases were male and 592 cases were female. The overall TT prevalence was 0.0325‰.The age of TT cases ranged from 25-86 years old, and concentrated in the 60-80 years old, only 58 cases were <50 years old.There were 12 cases of TT combined corneal opacity (CO) and the ratio was 1.2%. Sixty-four patients were cured by electrolysis trichiasis, the remaining 923 patients corrected by surgery interventions.?CONCLUSION: Based on the results of this study, trachoma blind is no longer estimated as a public health problem in Shaanxi province, as the detection rate of TT was less than 1‰ which is the goal of “elimination of trachoma” worldwide.
ABSTRACT
AlM: To investigate expressions of matrix metalloproteinase-2 ( MMP-2 ) and extracellular matrix metalloproteinase inducer ( EMMPRlN) in retinoblastoma (Rb) and the relationships between MMP-2, EMMPRlN and tumor development.METHODS:lmmunohistochemical technique was used to detect expressions of MMP-2 and EMMPRlN in 39 cases of paraffin embedded Rb samples. Quantitative analysis of expressions of MMP-2 and EMMPRlN were assessed by measuring the mean gray scale of Rb tissue with LElCA lM50 Color Pathologic Analysis System. The differences of expressions of MMP-2 and EMMPRlN in each clinical and pathological stage were statistically analyzed, and the same step was also undertaken to study the relationship between Rb with MMP-2 positive expression and that with EMMPRlN positive expression.RESULTS:The positive expression rate of MMP-2 was 90% (Gray value: 109. 64 ± 14. 52; 35/39), and that of EMMPRlN was 85% (Gray value:108. 01±13. 60;33/39). The expressions of MMP - 2 and EMMPRlN were significantly higher in tumors of glaucomatous stage (Gray value:108. 21±11. 47 and 107. 56±14. 32) than those in intraocular stage ( Gray value: 121. 13 ± 11. 32 and 119. 34 ± 12. 66; P<0. 01 and P<0. 05). And the same conclusion can be concluded between those in extraocular stage (Gray value: 91. 03 ± 11. 71 and 92. 26 ± 12. 93) with those in glaucomatous stage (P<0. 01 and P<0. 05). The expressions of MMP-2 and EMMPRlN were significantly higher in tumors with optic nerve invasion (Gray value:103. 89±13. 39 and 105. 23±14. 00) than those without optic nerve invasion ( Gray value: 118. 39 ± 15. 11 and 117. 53±16. 13) (P<0. 01 and P<0. 05).CONCLUSlON:The positive expression levels of MMP-2 and EMMPRlN may correlate with tumor infiltration and metastasis.
ABSTRACT
AlM: To evaluate the efficacy of intravitreal ranibizumab in idiopathic choroid neovascularization ( lCNV ) , compare the difference of the curative effect between type I and Ⅱof lCNV by optical coherence tomography ( OCT ) , further provide evidence of the to effectiveness of ranibizumab in the treatment of choroidal neovascularization to guide clinical treatment.METHODS:A retrospective analysis on the clinical data who were diagnosed as lCNV between October 2013 and June 2014 in our hospital were carried out. Totally 31 cases ( 9 cases of type I and 22 cases of type Ⅱ) accepted ranibizumab injection voluntarily. All of the patients were evaluated by ophthalmic examination, funduscopy and OCT before and after the injection, classificated according to OCT results. The best -corrected visual acuity ( BCVA) and maximum of edema thickness after ranibizumab treatment at 3mo follow-up were compared. RESULTS: After statistically analyzed, BCVA and maximum thickness of the retinal lesions of 31 patients (type I9 cases, type Ⅱ 22 cases) before and 1, 3mo after treatment had statistical significance. ln different types of retinal lCNV patients, BCVA and maximum thickness of the retinal lesions before and after treatment had no statistical significance. lt was said that ranibizumab intravitreal injection had effectiveness for lCNV, however, there were no significant effectiveness for typeI andⅡ lCNV.CONCLUSlON: Ranibizumab intravitreal injection has obvious effectiveness for lCNV. However, it has no effect on type I and Ⅱ lCNV. lts safety and long - term complications need for further study.
