Abstract?AIM: To observe the clinical efficacy of intravitreal Lucentis injection combined with panretinal photocoagulation ( PPR ) and compound trabeculectomy for neovascular glaucoma ( NVG) .?METHODS:A total of 14 cases (14 eyes) with NVG were collected from January to November 2015.All cases were treated with intravitreal lucentis injection, PPR and compound trabeculectomy by turns.Intraocular pressure ( IOP) , visual acuity and the complications at pre-or post-surgery were recorded, respectively.?RESULTS: Followed up for 3-6mo, the average IOP preoperatively was significantly decreased than that detected at post-operation ( 18.00 ±6.70 vs 41.65 ± 4.07mmHg, t=11.288, P<0.05).IOP less than 21mmHg with or without the usage of anti-intraocular pressure drugs was defined as the sign of successful or effective surgery, respectively.At the ultimate follow-up, 11 cases were successful, 2 cases were effective, and the success rate was 79%, effective rate was 14%.Only 1 case was applied cyclocryotherapy due to the uncontrolled IOP. Moreover, the results of visual acuity detection demonstrated that 6 eyes got a better visual acuity, 7 eyes remained the same condition and 1 case got no light perception. Meanwhile, 13 cases showed none iris neovascularization during the follow-up; 1 case got a reappearance of iris neovascularization on the third month, which was then dissolved subjected to the intravitreal lucentis injection in combination with PPR. One case developed post -operative hyphema and absorbed after 1wk. No shallow anterior chamber and eyeball atrophy happened.?CONCLUSION:Intravitreal lucentis injection combined with PPR and compound trabeculectomy is an effective and safe therapeutic strategy for the treatment of NVG.

Protein ubiquitin-like modification of Neddylation is an important post-translational modification mode of protein to widely regulate cell cycle, growth, development and other biological processes. Recent studies have found that MLN4924, small molecule inhibitor of Neddylation modification, has a significant anti-tumor effect, which can inhibit the tumor growth by inducing cell cycle arrest, senescence and apoptosis, and inhibiting tumor angiogenesis. This paper reviews the related mechanism research of cell programmed death induced by Neddylation modification pathway inhibitor MLN4924.

Objective To determine the variation of bone mineral density(BMD)and bone mineral content (BMC)in cadaveric lumbar vertebrae and investigate their significance in determining fracture modes and biomecha- nical properties.Methods The lumbar motion segments of the spines of 19 cadavers(mean age:56 years)were compressed to failure.The BMD and BMC of the cranial and caudal endplates were determined,along with the BMD and BMC of the upper and lower 1/3 transverse sub-endplate layers and the middle 1/3 transverse layer.The anteri- or,middle and posterior 1/3 vertical parts,anterior and posterior 1/2 vertical parts and the whole BMD and BMC were measured by using dual energy X-ray absorptiometry as well.All the data were analyzed statistically.Results Among the 19 segments,macrography after dissection revealed that 16 had been fractured,about 84.2%.The frac- ture always occurred in the centre or in the anterior part of the endplate.Within a vertebral body,the BMD and BMC of the cranial endplate were less than those of the caudal endplate,and the cranial 1/3 transverse layer and middle layer had lower BMD and BMC readings than the caudal layer.For the vertical region,from the anterior 1/3 to the posterior 1/3,or from the anterior 1/2 to the posterior 1/2,the BMD and BMC increased.For the endplate around the disc,the BMD of upper endplate was higher than that of the lower one,but the BMCs were equal.In one motion segment,the failure load correlated positively with BMD,and with the BMC of the endplate and the sub-endplate bone.Conclusion The variations in BMD and BMC within a vertebra and around a disc can explain why vertebral fractures are concentrated on the upper endplate,and why compressive fractures are always wedge-shaped.This un- derstanding can assist in the placement of inter-vertebral spacers.

Objective To measure the peak skin dose (PSD) in two cardiovascular interventional procedures,including coronary angiography (CA) and percutaneous transluminal coronary angioplasty (PTCA) using radiochromic film.Methods Gafchromic XR-RV3 film was selected to measure PSD in two hospitals.The films were placed on the table underneath the patient during interventional surgery.The kV,mA,fluoroscopy time,dose-area product (DAP),and cumulative dose at reference point and other relevant information were recorded for all cases.Using the Epson V750 flatbed scanner for scanning and analyzing film,FilmQA software was chosen to analyze the pixel value of red,green and blue color channels.The PSD was determined using red channel data.The correlation and linear regression analysis between PSD and device-displayed parameters was carried out.Results PSD were measured using XR-RV3 film for 26 CA and 19 CA + PTCA procedures.For CA procedures,maximum fluoroscopy time,cumulative dose and DAP were 17.62 min,1 498.50 mGy and 109.68 Gy · cm2,respectively.The maximum PSD was 361.20 mGy.However,for CA + PTCA procedures,maximum fluoroscopy time,cumulative dose and DAP were 64.48 min,6 976.20 mGy and 5 336.00 Gy· cm2,respectively.One patient with CA + PTCA procedures was found to have received the PSD value more than 2 Gy,up to 2 195.70 mGy.DAP was found to be a good indicator (R2 =0.815,P <0.05) of PSD for CA procedure,and correlated with cumulative dose (R2 =0.916,P < 0.05) for CA + PTCA procedures.Conclusions The PSD value of some patients in cardiac interventional procedures would exceed 2 Gy,the threshold of deterministic effects recommended by ICRP.The dose-related parameters value showed on DSA device can only used to estimate PSD roughly.Using XR-RV3 film accurate measurement of the PSD in interventional projects is a very fast and effective method.

OBJECTIVE:
To develop the single-tube one-step methylation variable position (MVP) analysis technology-single-tube post-digestion PCR-melting curve analysis (PDP-MCA).
METHODS:
Based on differentially methylated region (DMR) reported previously as the model, a set of primers with different melting temperatures of products in the two sides of MVP were designed. By using the FastDigest methylation-sensitive restriction enzyme (MSRE), DNA digestion, multiplex amplification, MCA detection and MCA profiles were performed in a single reaction tube. Same samples (peripheral venous blood, semen, and vaginal fluid, 5 samples each type) were tested by single-tube one step MVP and traditional MSRE-PCR MCA technology. To verify the feasibility of this method, the results were compared with that of the traditional technology. The MCA/HRM profiles of different samples were analyzed and compared.
RESULTS:
When the melting temperature of the fragments had a differential of 2 degrees C, the MCA melting peaks separated well, and MCA detection after multiplex amplification was successful. The single-tube PDP-MCA assay was developed, which integrated multiple reactions (digestion, amplification and detection) into one tube. By this method, the sample-specific profiles and data were analyzed in 2 h, which is similar to that of the traditional method. The rapid classifications of the samples were also realized.
CONCLUSION
Multiplex MVPs can be analyzed in a single closed-tube. The single-tube PDP-MCA technology is a simple, fast, and automatable method. It can be used for detection of DNA methylation variations.

Background The integration of segregated pathways from the two eyes first appears in V1 neurons,where it not only plays a critical role in the generation of a three-dimensional visual representation.Abnormal visual experiences in critical period usually lead to amblyopia and binocular integration defects.Objective Present study was to investigate how neurons of kitten coordinate their activity patterns in response to synchronous dichoptic stimulus inputs in striate cortex.Methods Spike rate and local field potential(LFP) gamma band(20-90Hz) power of three kitten(1-1.2Kg,8-10 weeks old) to monocular and synchronous dichoptic presented gratings were assessed for 28 binocular neurons in V1 of kitten by in vivo extracellular record method under anaesthesia and paralysis.Ocular dominance index(ODI) and binocular integration index(BII) were assessed and the correlation between these two indexes were analyzed.Results In 28 cells with binocular characteristic,the absolute value of spike-ODI was significant larger than that of LFP-ODI(t=2.606,P=0.021).A positive linear correlation between the ocular preferences of spike and LFP was found(R2=0.513,F=27.423,P=0.003).In dichotic trails,binocular facilitation with BII for spike was 2.348±0.996,showing a significant reduce in comparison with BII for LFP(3.678±1.974)(t=2.671,P=0.019).Binocular integration index for two signals were greater when monocular responses of both eyes were similar(P=0.035 and P=0.124,respectively).Conclusion Both spike rate and gamma band power of LFP exhibited binocular facilitation to synchronous presented dichotic stimuli with significant facilitation induced by balanced monocular responses.Spiking activity and LFP reflect neural activities of different spatial scales and source components.
