BACKGROUND Non-proliferative diabetic retinopathy(NPDR)poses a significant challenge in diabetes management due to its microvascular changes in the *** photocoagulation,a conventional therapy,aims to mitigate the risk of progressing to proliferative diabetic retinopathy(PDR).AIM To compare the efficacy and safety of multi-spot vs single-spot scanning panretinal laser photocoagulation in NPDR *** Forty-nine NPDR patients(86 eyes)treated between September 2020 and July 2022 were *** were randomly allocated into single-spot(n=23,40 eyes)and multi-spot(n=26,46 eyes)*** outcomes,including bestcorrected visual acuity(BCVA),central macular thickness(CMT),and mean threshold sensitivity,were assessed at predetermined intervals over 12 *** reactions were also *** Energy levels did not significantly differ between groups(P>0.05),but the multi-spot group exhibited lower energy density(P0.05).CONCLUSION While energy intensity and safety were comparable between modalities,multi-spot scanning demonstrated lower energy density and showed superior short-term improvements in BCVA and CMT for NPDR patients,with reduced laser-induced damage.

Gold nanoparticles (nano Au)/titanium dioxide (TiO2) hollow microsphere membranes were prepared on the carbon paste electrode (CPE) for enhancing the sensitivity of DNA hybridization detection. The immobilization of nano Au and TiO2 microsphere was investigated with cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The hybridization events were monitored with EIS us-ing [Fe(CN)6]3-/4- as indicator. The sequence-specific DNA of the 35S promoter from cauliflower mosaic virus (CaMV35S) gene was detected with this DNA electrochemical sensor. The dynamic detection range was from 1.0×10-12 to 1.0×10-8 mol/L DNA and a detection limit of 2.3×10-13 mol/L could be ob-tained. The polymerase chain reaction (PCR) amplification of the terminator of nopaline synthase (NOS) gene from the real sample of a kind of transgenic soybean was also satisfactorily detected.

Using the data specially observed on the Bohai Sea oil platform by the authors for studying thermocline for two weeks, the thermocline depth, the temperature and the salinity of the layers below and above the thermocline were numerically modelled. The model is based on the Stigebrandt model and some important supplements are made in this paper in accordance with the local condition of the sea. The modelling results fit well in the observations. It is proved that the entrainmem due to both the tide and the wind can give rise to rather intense mixing cross the thermocline. This process makes the temperature rising below the thermocline,and causes the nutrient increasing above it,which has important significance for the marine physical environment and the marine organism.

In this paper, the color elements of painting in the package design and color selection are studied, finding that although the color painting on the function of packaging design and color is different, but the color elements of painting can be used in the design of the packing. Through the research and analysis, any basic training is useful and necessary, and any basic training is step by step and also whether to study painting masters can learn to essence. It＇s important that design excellent works in the future.

Ammonia volatilization losses from urea applied as a basal fertilizer and a top dressing at tillering stage in a wheat field of Taihu Region, China, were measured with a micrometeorological technique. Urea as fertilizer was surface broadcast at 81 (low N) and 135 (high N) kg N ha-1 as basal at the 3-leaf stage of the wheat seedling on December 2002, and 54 (low N) and 90 (high N) kg N ha-1 as top dressing on February 2003. Ammonia volatilization losses occurred mainly in the first week after applying N fert…

为了揭示旋流周向位置对下游进口导叶(IGV)气动特性的影响机理,采用数值模拟方法计算并分析了进口旋流在多个不同周向位置处时旋流与通道内二次流的相互作用原理,进而重点分析了3个典型位置算例中的二次流动、涡系结构和熵增情况。研究表明:进口旋流与通道内固有二次流动之间的相互作用及黏性耗散是旋流所造成损失的主要原因;通道损失最大的工况不在旋流正对叶片头部时出现,而是在旋流靠近叶片头部近压力面一侧时产生;此外,旋流与通道涡相互作用,在进口旋流达到一定强度时会在叶片尾缘附近形成诱导涡。

Coronary arteriovenous fistula （CAVF） is an uncommon anomaly, occurring 0.1% to 0.2% atcoronary angiography. Although majority of CAVF are small and silent, they may cause fistula-related complications, especially in the elderly patients. Therapeutic strategies for CAVF have not been clearly defined because of uncertainty of its natural history. Surgical repair for CAVF is generally recommended in the presence of symptoms of heart failure or significant left-to-right shunt. Various devices have been used during interventional treatment of CAVF through percutaneous approach.3 In this study, we report a rare female case of coronary-pulmonary artery fistula concomitant with a giant saccular coronary artery aneurysm, arising from the left anterior descending artery and draining into pulmonary artery. It was eventually closed by percutaneous intervention with coils.
