AIM:To compare the clinical efficacy of three combined surgical treatments for cataract induced by silicone oil -filled eye.
METHODS: The data of 75 eyes of 75 patients with cataract induced by silicone oil-filled eye were reviewed. Those patients were divided into group A, B, C. The patients in group A were treated by phacoemulsification combined with silicone oil removal through pupil and IOL implantation, the patients in group B were treated by phacoemulsification combined with silicone oil removal through 23G vitrectomy system and IOL implantation, the patients in group C were treated by phacoemulsification combined with silicone oil removal through 20G vitrectomy system and IOL implantation. The operation time, intraocular pressure, best corrected visual acuity ( BCVA ) , discomfort days and complications before and after the surgery were compared.
RESULTS: The differences of the intraocular pressure were not statistically significant between the three groups after the surgery. The BCVA of the three groups were all improved, but the differences were not statistically significant between three groups. The differences in postoperative complications showed no statistically significant. Otherwise, group A and B cost less operation time. The discomfort days of group A were less than other groups.
CONCLUSION: Three different surgical methods were safe and effective, appropriate surgical approach could be chosen according to the patients' clinical manifestations. For patients with cataract induced by silicone oil-filled eye whose retina recovered well, phacoemulsification combined with silicone oil removal through pupil and IOL implantation is a time-saving, safe and effective method.

AIM:To investigate the findings of the eyes which were examined preoperatively by three mirror contact lens before the implantation of implantable collamer lens ( ICL) . To analysis the retinal pathological changes and to explore the clinical analysis of early diagnosis and treatment in retinopathy on fundus examination before operation.
METHODS:The retrospective case series study included 127 eyes of 64 patients who underwent phakic intraocular lens implantation were received the fundus examination by three mirror from April 2011 to April 2012 in our hospital. The age, refractive diopter, the findings of Goldmann three mirror examination and the condition of retinal photocoagulation were analysed and concluded.RESULTS:A total of 34 eyes (26. 8%) out of all 127 eyes ( 64 cases ) were found to have peripheral retinal pathological changes. Eight eyes ( 6. 3%) with retinal holes, 15 eyes(11. 8%) with retinal lattice degeneration, 5 eyes ( 3.9%) with retina cream degeneration, 3 eyes (2.4%)with retinal paving stone degeneration,2 eyes with vitreoretinal adhesion and traction, 1 eye ( 0. 8%) with retinal hemorrhage. Twenty-five cases were given retinal photocoagulation and then received the ICL implantation after 3mo. The follow - up time was 1a. No retinal detachment happened.
CONCLUSION: Phakic before intraocular lens implantation for fundus examination by three mirror is contributed to find the peripheral retinal pathological changes and abnormity. And make the appropriate treatment before operation for improving the security of operation, it can also give help to the postoperative follow-up of the fundus of these patients.

?AlM: To analyze the result of ultrasound biomicroscopy ( UBM ) of patients with rhegmatogenous retinal detachment ( RRD ) who need to perform pars plana vitrectomy ( PPV ) to explore the value of clinical application of UBM at preoperation.
?METHODS:Patients who underwent PPV for RRD in our hospital from January to December 2014 were selected. The preoperative results of UBM were recorded and the positive findings of UBM were analyzed, the value of preoperative application of UBM was investigated.
?RESULTS:Totally 356 cases (357 eyes) of patients with RRD were received PPV. All patients were examined by UBM, 122 eyes ( 34. 17%) were positive, 56 eyes were ciliochoroidal detachment, 28 eyes were narrow anterior chamber angle, 6 eyes were chamber angle-closure, 28 eyes were ciliary body cyst, 4 eyes were iris cyst, 11 eyes were anterior proliferative vitreoretinopathy, 1 eye was retinal cyst. There were 12 eyes existing two lesions at the same times. ln this study, patients with choroidal detachment was detected by UBM in 56 eyes, the positive rate was 15. 7%, while 25 eyes was detected by B -ultrasonography, the positive was 7. 0%. The difference was statistical significant(χ2=13. 382, P<0. 05).
?CONCLUSlON: The patients with RRD have underwent PPV for the condition of illness, preoperative UBM can be examined to detect the condition of anterior chamber angle, iris, ciliary and anterior choroid, which is significant for comprehensively understanding the preoperative condition of patients, estimating the difficulty of the operation, and guiding operation and the postoperative follow-up.

Objective To investigate the common pathogens of neonatal bacterial meningitis in the past 5 years,and to evaluate the brain injury in the acute phase through amplitude-integrated electroencephalogram (aEEG),brainstem auditory evoked potential (BAEP) and brain MRI.Methods Sixty children were selected from the past 5 years who were treated in Department of Neonatology,Guangzhou Women and Children's Medical Center in March 2011 to March 2015 as the objects of study.According to the results of etiological culture,the children were divided into streptococcus lactis group (14 cases),escherichia coli group (10 cases),other positive bacteria group (11cases) and culture-negative group (25 cases).The results of aEEG,BAEP and brain MRI of brain injury in the acute phase of these 4 groups were compared.Results Twenty-nine cases of the 60 patients (48.3％) showed positive blood culture,and 14 cases (23.3％) showed positive cerebrospinal fluid (CSF) culture.Streptococcus lactics and escherichia coli were found to be the most common pathogens that caused neonatal bacterial meningitis.By evaluating the cerebral function in the acute phase of 57 cases,it was found that aEEG total abnormal rate was 61.4％,escherichia coli group abnormal rate was 80.0％,while moderate to severe damage seemed to be the most remarkable feature.The abnormal rate was of statistical significance between escherichia coli group and culture-negative group (x2 =3.941,P =0.047).Forty-eight cases manifested potential anomaly evoked by brainstem auditory,with the total abnormal rate as 84.2％.A significant increase in the ratio of severe hearing loss was found in children with bacterial meningitis which was caused by escherichia coli and streptococcus agalactiae.The abnormal rate was of statistical significance between escherichia coli group and culture-negative group (x2 =4.399,P =0.036),and hearing damage caused by escherichia coli was more serious than that in other bacteria group.Of these 57 cases,MRI total abnormal rate was 77.2％,with hydrocephalus as the most common complication.Of the 44 abnormal cases,16 cases showed hydrocephalus,6 cases of which were from the escherichia coli group.The second most common complication was subdural effusion.And another 5 cases showed cerebral softening,3 cases of which were from the escherichia coli group.The data suggested that escherichia coli meningitis easily combined hydrocephalus and brain softening.Conclusions The main pathogens of neonatal bacterial meningitis is streptococcus agalactiae and escherichia coli.The brain injury in neonatal bacterial meningitis caused by escherichia coli is more serious than those caused by other pathogens.

OBJECTIVETo confirm the inhibitory effect of Chinese herbs of acid taste on melanin synthesis.

METHODSActive ingredients of 22 kinds Chinese herbs of acid tastes were extracted by alkali extraction and acid precipitation, alcohol extraction, and water extraction, respectively, which was then dispensed into 25.00, 12.50, and 6.25 g/L suspension. Their effects on activities of tyrosinase were detected using mushroom-tyrosinase-DOPA speed oxidation. Their inhibition rates on activities of tyrosinase were respectively compared with inhibition rates of 1.0, 0.5, and 0.1 mmol/L arbutin.

RESULTSThe 22 kinds Chinese herbs of acid taste included Cornus Officinalis, Crataegus pinnatifida, dark plum fruit, Schisandra Chinensis, Chaenomeles sinensis Koehne, Reynoutria japonica Houtt, Achyranthes Bidentata, Sanguisorba officinalis L., Semen Ziziphi Spinosae, Herba Ecliptae, blueberry, immature bitter orange, submature bitter orange, Prunus mume Var, Hovenia acerba Lindl., Fructus Mori, Pomegranate Rind, white paeony root, Rosa laevigata Michx., Portulaca oleracea L, Terminalia chebula Retz, Rhus chinensis Mill. Their alkaline extractions showed inhibition to activities of tyrosinase to different degrees except Herba Ecliptae. Of them, the highest inhibition rate (88.49% ± 9.98%) was got by dark plum fruit at 25 g/L, while the lowest inhibition rate (11.22% ± 3.36%) was got by immature bitter orange at 6.25 g/L. Their alcohol extractions showed inhibition to activities of tyrosinase to different degrees except Herba Ecliptae. Of them, the highest inhibition rate (75.92% ± 5.57%) was got by Hovenia acerba Lindl. at 25 g/L, while the lowest inhibition rate (9.60% ± 1.15%) was got by submature bitter orange at 6.25 g/L. Their water extractions all had inhibition on activities of tyrosinase. Of them, the highest inhibition rate (54.23% ± 3.56%) was got by Fructus Mori at 25 g/L, while the lowest inhibition rate (10.25% ± 1.83%) was got by Semen Ziziphi Spinosae at 6.25 g/L. Compared with 1 mmol/L arbutin water solution, alkaline extractions of dark plum fruit, Schisandra Chinensis, Rhus chinensis Mill., Rosa laevigata Michx., blueberry, Chaenomeles sinensis Koehne, Portulaca oleracea L, Fructus Mori, Achyranthes Bidentata, Pomegranate Rind; alcohol extractions of dark plum fruit, Rhus chinensis Mill., Pomegranate Rind, Hovenia acerba Lindl., Crataegus pinnatifida, Achyranthes Bidentata; water extractions of Chaenomeles sinensis Koehne, blueberry, and Fructus Mori at 25 g/L got obviously higher inhibition rates (P < 0.05, P < 0.01). Compared with 0.5 mmol/L arbutin water solution, alcohol extraction of Chaenomeles sinensis Koehne and alcohol extraction of dark plum fruit at 12.5 g/L got obviously higher inhibition rates (P < 0.05, P < 0.01).
