AIM: To retrospectively analyze the effect of different surgical treatment on intraocular foreign bodies, according to different types and position.
METHODS: Clinical data of 46 cases diagnosed with intraocular foreign bodies from June 2010 to April 2013 were retrospectively analyzed.
RESULTS:Intraocular foreign bodies in anterior segment could be removed or magnetically attracted directly, intraocular foreign bodies in posterior segment could be attracted if there was accurate location. Vitrectomis was more favorable for the non magnetic or intraocular foreign bodies in posterior segment. In 46 cases, all intraocular foreign bodies ( 100%) in posterior segment were removed successfully. Among them the functional cure in 33 cases ( 72%) , the anatomical cure in 12 cases ( 26%) , discharged in 1 case (2%).
CONCLUSION:The aim of operation is to reconstruct of eyeball structure preserve and restore visual function. We should find more appropriate mode of operation and timing of surgery according to the foreign bodies'different types and injury of eyeball, reduce complications, preservation eyeball and improve visual function.

OBJECTIVETo evaluate the clinical efficacy of manipulative reduction combined with percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP) in treating osteoporotic vertebral compression fracture (OVCF) using meta-analysis method, in order to provide a reference for clinical treatment.

METHODSA systematic computer-based search (from January 1987 to April 2014) from CNKI, Wanfang database, Web of Science and PubMed were performed for the collection of controlled clinical researches on manipulative reduction combined with PVP or PKP in treating OVCF. The quality of selected researches was evaluated. Meta-analysis was adopted to evaluate visual analog scale, Cobb angle, anterior height ratio of the injured vertebra.

RESULTSA total of 7 researches of 410 patients were included in the present analysis, there were 5 RCTs and 2 non-RCTs and all come from China. Manipulative reduction combined with PVP could got better improvement in Cobb angle (WMD=-7.35; 95%CI: -12.15, -2.54) and anterior height ratio of the injured vertebra (P<0.01) than simple PVP, but no significant difference was found in improvement of visual analog scale (WMD=-0.01; 95%CI: -0.45, 0.42). There were no significant differences in the improvement of visual analog scale, Cobb angle, anterior height ratio of the injured vertebra between manipulative reduction combined with PKP and simple PKP (P>0.05).

CONCLUSIONCompared with simple PVP, manipulative reduction combined with PVP may result in more clinical efficacy on the improvement of Cobb angle and anterior ratio of the injured vertebra. And compared with simple PKP, manipulative reduction combined with PKP has no obvious advantages on the improvement of visual analog scale, Cobb angle, anterior height ratio of the injured vertebra. However, the number and quality of the literatures, may resulted in the effect of mistrust, so more large sample and high-quality RCTs are needed in future.

Diversity-oriented synthesis (DOS) aims to efficiently generate collections of small molecules with diverse appendages, functional groups, stereochemistry and skeletons, thus yielding diverse biological activities capable of modulating a wide variety of biological processes. In this review, we discussed the common strategies employed in DOS with specific examples from recent literature, including reagent-based approach, substrate-based approach, build-couple-pair strategy and privileged substructure-based DOS. The application of some DOS libraries in drug discovery is also presented.

Objective To investigate the effects of RDP1258 on survival of rat cardiac allograft. Methods RDP1258 was synthesized and the model of rat heart abdominal transplantation was established. Animals were divided into four groups. Group 1 received no immunosuppression. Group 2 received CsA alone. Group 3 received RDP1258 alone. Group 4 received RDP1258 and subtherapeutic CsA. In all cases RDP1258 was administrated intraperitoneally and CsA was gavaged. Light and electron microscopic examinations were taken . Transplanted hearts were monitored daily by direct palpation. Results The purity of synthesized RDP1258 was over 95 % and the molecular weight was in accord with theoretical value. The histology and the ultrastructure changed little in grafts in group 3 and group 4. Survival of rat cardiac allograft was significantly prolonged in group 4. Conclusions RDP1258 can suppress acute rejection. Perioperative administration of RDP1258 in combination with CsA can significantly prolong survival of rat cardiac allograft.

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.

Objective To investigate the association between the lumbar vertebral fracture damage degree with the fracture classification,injury score,kyphosis deformity and nerve function injury.Methods According to the damage degree of posterior lig ament complex(PLC),the patients were divided into the PLC intact group and PLC injury group.Its relationship with PLC injury was researched by evaluating the fracture classification,injury score and nerve function injury situation in the two groups.Results The LCS score and TLICS score in the PLC injury group were (7.1±0.8) points and (8.2±0.6) points,which were higher than (5.7±0.5) points and (4.6±0.7) points in the PLC intact group.The Denis score in the PLC injury group was more serious.The Cobb angle in the PLC injury group was 29°,and which in the PLC intact group was 19°.The proportion of nerve function insufficiency in the PLC injury group was 89％,while which in the PLC intact group was only 60 ％.Conclusion The thoracolumbar vertebral fracture is closely related with PLC.PLC damage degree is positively correlated with the fracture classification,injury score,kyphosis deformity and nerve function injury degree.
