·AIM: To investigate a surgical method of modified lensectomy within combined lensectomy and vitrectomy surgery in traumatic eyes.·METHODS: Clinical records were studied retrospectively for a series of consecutive 27 traumatic patients who were performed vitrectomy combined with lensectomy surgery. A modified lensectomy through pars plana incision of sclera was performed to these cases and lens capsule was reserved. It was then combined with vitreous and retinal operations.·RESULTS: All lens were removed completely with lens capsule remained. All cases achieved improved visual acuity.Intraocular pressure (IOP) in all eyes was in normal range after surgery.·CONCLUSION: The modified lensectomy is a safe and effective surgery manner which has few complications and is more suitable for traumatic eyes in the combined lensectomy and vitrectomy surgery.KEYWORDS:ocular trauma; lensectomy; vitrectomy

·AIM: To investigate the effect of vitamin A on the conjunctival goblet cells of rat after corneal transplantation.·METHODS: Rat graft rejection models of corneal transplantation were established. SD rats were receptor and Wistar rats were donors. After corneal allografts were performed, 48 SD rats were randomly divided into three groups, 16 rats in each group. Group A was blank control group; group B was treated by oculotect gel (containing vitamin A); group C was treated by 1g/L dexamethasone eyedrops. Besides, group D was normal unoperated eyes.Slit-lamp microscope was employed to record and compare rejection index (RI) of corneal transplantation. Through HE,PAS staining of conjunctival histological sections and image analysis system, the number and morphology of conjunctival goblet cells were observed and analyzed between operation group and normal group.·RESULTS: The HE, PAS staining detection showed that the number of conjunctival goblet cells in oculotect gel group,1g/L dexamethasone eyedrops group and control group is lower than that in normal group after surgery (P＜0.01). The number of conjunctival goblet cells in oculotect gel group and 1g/L dexamethasone eyedrops group is higher than that in control group (P＜0.05). The number of conjunctival goblet cells in 1g/L dexamethasone eyedrops group is higher than that in oculotect gel group (P＜0.05).·CONCLUSION: The results indicate that vitamin A may inhibit the decrease of conjunctival goblet cells after corneal allograft rejection in rats.

AIM: To investigate the alterations of tear film after sutureless large incision manual cataract extraction (SLIMCE). METHODS: Sixty-eight SLIMCE operation eyes were studied with slit-limp microscope, break- up time (BUT), SchirmmerⅠtest (SⅠt),and fluorescence(FL) to observe the alterations of tear film at different time points in postoperation. Impression cytology and microphoto-analyses technique were also applied to observe the goblet cells at different time points postoperation(7,14,30,60,90 days). RESULTS: Subjective complaint of dry eye within 90 days after the operations were significantly increased compare with preoperations(5-27,23,19,16,13; 2-16,14,8,6,3). The schirmmer Ⅰ test were greatly increased in 14 days postoperation(10.1±4.5;15.0±4.7,13.8±5.7),the mean scores of fluorescence increased (0-17,9,5;0-8,3,1) and the mean break-up time decreased in 30 days post-operation(10.3±2.2;5.5±2.3,7.0±2.4,7.9±2.2) (P<0.05). CONCLUSION: SLIMCE operation have effect on the stability of tear film.

Objective To explore the predictive value of ventricle late potential (LP) for arrhythmic events in the patients with Brugada syndrome. Methods Totally 43 patients with Brugada syndrome were divided into symptom group (n=24) and asymptom group (n=19).Signalaveraged electrocardiography(SAECG) was performed to analyze characteristics of LP in all subjects.The occurrence of arrhythmic events was observed in all patients during the dynamic follow-up for (33.8±9.0) months.Results There were 22 cases (91.7％) and 7 cases (36.8％) with LP positive in patients with symptom and asymptom,respectively.The incidences of arrhythmic events were 72.4％ in Brugada syndrome patients with positive LP and 14.3％ in patients with negative LP,respectively.The relative risk (RR,95％ CI) for LP prediction of the arrhythmic events was [5.1,(1.4～ 18.6)] (P =0.002). ConclusionsLP may be one of effective factors predicting arrhythmic events in the patients with Brugada syndrome.

OBJECTIVETo observe the effect of acupuncture along affected meridian on the mem- brane metallo-endopeptidase (MME) gene expression of migraine patients without aura (MO) of Gan-yang hyperactivity syndrome (GYHS).

METHODSTotally 20 MO patients of GYHS were randomly assigned to the acupoint group (acupuncture along affected meridian) and the non-acupoint group, 10 cases in each group. Needling was performed once per day for 10 consecutive days. Gene chip technology was used to obtain two sets of gene expression profiles and analyzed using Gene Ontology (GO).

RESULTSIn the acupoint group, MME gene expression decreased after needling (P = 0.0023).That gene was rich in the beta-amyloid metabolic process (P = 3.16E-05) and the peptide metabolic process (P = 0.009612). Its expression was not seen in the non-acupoint group.

CONCLUSIONThe effect of point selection along affected meridian could be achieved possibly by regulating the MME gene expression.
