AIM:To explore the cataract suspensory ligament rupture and artificial lens implantation suture fixation into capsular bag without capsular tension ring(CTR).METHODS:We reviewed 20 cases of 20 cataract suspensory ligament rupture without CTR intraocular lens (IOL) implantation fixation in our department from Jan.2012 to Dec.2016.The needle crossed into ocular ciliary sulcus, in the equator of the eye ball which suspensory ligament rupture from, then the needle crossed out 1.5mm away from the angle of sclera.Sutures fixed on the IOL, then the artificial lens implantation in the pouch, carried out in accordance with the Z type suture, or to the beforehand prepared triangle scleral flap.The visual acuity, intraocular pressure, the anterior chamber and the IOL position were measured after operations.RESULTS:All of the postoperative visual acuity improved different level.The postoperative best corrected visual acuity(BCVA) was ≥0.8 in 4 eyes(20%), 0.5-0.6 in 7 eyes(35%), 0.3-0.4 in 8 eyes(40%), 0.1 in 1 eye(5%) because of the glaucoma optic atrophy.There were 12 cases with mild corneal endothelium edema, 4 cases exudation membrane in the pupil area, 2 cases hyphema, all of which recovered after treatment.There were 2 eyes with vitreous prolapse in the pupil, 1 case appeared mild IOL center deviation and no special treatment for the vision did not be involved.Followed up for 6mo, displaced stitches or artificial lens shift did not occur.CONCLUSION:Without CTR, the IOL implantation and suture fixation in capsular bag during cataract surgery is a surgical method for basic-level hospitals.

Objective To investigate the effect of eosinophils(EOS)in asthmatic guinea pigs airway and explore the mechanism of antiasthma by inhaled arsenic trioxide. Methods The guinea pigs asthma models were established with ovalbumin(OVA)challenge method,2 groups received inhaled different doses of arsenic trioxide,and three control groups respectively received normal saline inhaled and high dose of arsenic trioxide by intraperitoneal injection and dexamethasone(DEX)intraperitoneally. EOS invaded and apoptosis with all of the groups were assessed after 7 days intraperitoneal injection or inhalation. Results Compared with group of inhaled normal saline, both EOS invaded and apoptosis in bronchus submuconsa were significantly different(P0.05)among groups of inhaled low dose arsenic trioxide [2.0 mg(kg?d)]and intraperitoneal injection with higher dose arsenic trioxide[5.0 kg/(kg?d)]and DEX[10 mg/(kg?d)]for these two parameters. Conclusions The mechanism of arsenic trioxide antiasthma with arsenic trioxide can decrease EOS amount in bronchial submucosa and accelerate EOS apoptosis, and relieve bronchial inflammation in asthma. For inhaled lower dose arsenic trioxide or intraperitoneal injection with high dose arsenic trioxide ,the effect of EOS is equivalent. The antiasthma effect of inhaled lower dose arsenic trioxide[2.0 mg/(kg?d)]is equivalent to intraperitoneal injection higher dose[5.0 mg/(kg?d)],and may be safe comparatively. The mechanism of antiasthma by inhaled arsenic trioxide is the same with DEX.

Trehalose is a naturally occurring non-reducing disaccharide. This sugar has been known as a protector of biomembrane and macromolecules. And it has been widely used in foods, medicines, cosmetics. Trehalose synthase (TreS) is an intramolecular transglycosylase. It can catalyze the conversion of maltose into trehalose in one step. As the simple protocol and cheap substrate, it is very prospect in the industrial production. Here we have discussed the properties, catalytic mechanism and gene-engineering of TreS, and also proposed some solutions to its present research problems.

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 observe enhancing effect of nerve regeneration on peripheral nerve defect models bridged by VPA/PRGD conduit combined with adipose derived mesenchymal stem cells (ADSCs).Methods From February,2013 to August,2014,the hollow nerve scaffolds were constructed by PRGD and VPA.The activity of AD SCs proliferation was tested through the method of CCK-8.Moreover,the effect of VPA/PRGD conduit combined with ADSCs on peripheral nerve regeneration was evaluated,as well as recovery of motor function following sciatic nerve resection in rats.A 10 mm sciatic nerve deficit was created in a rat model and bridged by VPA/PRGD conduit combined with ADSCs (group A),VPAfPRGD conduit (group B) and autograft (group C) respectively.The results was analyzed by the method of group t-test of SPSS 19.0.Results At 3 d,6 d,9 d,CCK-8 test showed that the OD value of groups VPA/PRGD and control has no significance(P ＞ 0.05).At 12 weeks after surgery,the numbers of regenerated nerve proximal to the tube of group A (268±7.48),group B (269±6.86) and group C (271±7.55),had no significant difference between two groups(P ＞ 0.05).The numbers of regenerated nerve in the tube of group A (257±6.19) and group C (260±5.60) were significantly higher than those of group B (229±5.08) (P ＜ 0.05).There was no significant between groups A and C (P ＞ 0.05).The numbers of regenerated nerve distal to the tube of group A (246±5.89) and group C (247±5.02) were significantly higher than those of group B (214±7.55) (P ＜ 0.05).There was no significant between groups A and C (P ＞ 0.05).Conclusion These promising results illustrate that this novel VPA/PRGD combined with ADSCs conduit can obviously facilitate the regeneration of injured nerve in rats.
