AIM: To investigate the complications of intravitreal triamcinolone acetonide (IVTA) for the treatment of macular edema, and to determine the risk factors for intraocular pressure (IOP) elevation. METHODS: Charts of patients with macular edema secondary to branch retinal vein occlusion (BRVO), diabetic retinopathy and uveitis who had received IVTA injections were reviewed to document its complications. IOP elevation was defined as a pressure of ≥24mmHg at some point during follow-up. Multivariate logistic regression analysis was performed to characterize baseline risk factors for this elevation. RESULTS: The study included 111 eyes of 65 female and 46 male patients with a mean follow-up of (11.6±5.1) months. Of the 111 eyes, 52 (46.8%) had macular edema secondary to BRVO, 44 (39.6%) had clinically significant diabetic macular edema (CSDME) and 15 (13.5%) had non-infectious uveitis with macular edema. IOP was recorded ≥24mmHg in 38 eyes (34.2%) during the follow-up. Higher baseline IOP (P =0.022), younger age (P =0.003), and male gender (P = 0.014) were significant risk factors for IOP elevation after IVTA injection. Eyes with prior vitrectomy were less likely to have IOP elevation (P =0.054). Two eyes (5.2% of eyes with increased IOP) underwent trabeculectomy, and 9 eyes (16.3% of the phakic eyes) necessitated cataract surgery. Other complications included branch vein occlusion (1.8%), sterile endophthalmitis (0.9%) and pseudohypopyon (0.9%). CONCLUSION: IVTA has side effects with IOP elevation and cataract formation being the two most common. A subset of patients is more prone to developing increased IOP following IVTA, namely, younger male patients with higher baseline IOP.

Molybdenum trioxide(MoO_(3))has recently attracted wide attention as a typical conversion-type anode of Li-ion batteries(LIBs).Nevertheless,the inferior intrinsic conductivity and rapid capacity fading during charge/discharge process seriously limit large-scale commercial application of MoO_(3).Herein,the density function theory(DFT)calculations show that electron-proton co-doping preferentially bonds symmetric oxygen to form unstable HxMoO_(3).When the-OH-group in HxMoO_(3) is released into the solution in the form of H_(2)O,it is going to form MoO_(3-x)with lower binding *** the means of both electron-proton co-doping and high-energy nanosizing,oxygen vacancies and nanoflower structure are introduced into MoO_(3) to accelerate the ion and electronic diffusion/transport *** from the promotion of ion diffusion kinetics related to nanostructures,as well as both the augmentation of active sites and the improvement of electrical conductivity induced by oxygen vacancies,the MoO_(3-x)/nanoflower structures show excellent lithium-ion storage *** prepared specimen has a high lithium-ion storage capacity of 1261 mA h g^(-1)at 0.1 A g^(-1)and cyclic stability(450 cycle),remarkably higher than those of previously reported MoO_(3)-based anode materials.

BACKGROUND： Some research exists on the effect of non-pharmacological approaches for labor pain relief However, there is limited information about effectiveness of breathing exercises in pregnant women to reduce maternal pain during labor. OBJECTIVE： To determine whether breathing exercises for pregnant women during the second stage of labor have beneficial effects on maternal pain, duration of labor, and the first-minute Appearance, Pulse, Grimace, Activity and Respiration （APGAR） scores. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS： This randomized clinical trial involved 250 pregnant women, who were randomly divided into two groups： intervention group （IG; n = 125） and control group （CG; n = 125）. IG received one session breathing exercise training and performed breathing exercises during the second stage of labor versus the CG that did not receive any breathing exercise training. MAIN OUTCOME MEASURES： The effects of breathing exercises on maternal pain were determined by Visual Analogue Scale （VAS）, duration of the second stage of labor, and the first-minute APGAR scores. RESULTS： The mean age of the participants was （23.2 _＋ 4.2）（range： 18 to 42） years. Both IG and CG had similar baseline characteristics in terms of age, education level, occupation, and smoking （P 〉 0.05）. The mean VAS scores of IG and CG were （88.2 ＋_ 6.3） and （90.5 ＋_ 7.0）, respectively （P 〈 0.001）. The duration of the second stage of labor was （369.6 ＋ 92.0） s for IG and （440.7 ＋ 142.5） s for CG （P 〈 0.001 ）. The mean first-minute APGAR scores were （8.84 ＋ 0.50） for IG and （8.73 ＋ 0.89） for CG （P 〉 0.05）. CONCLUSION： Based on this study, breathing exercises with deep inhalation and exhalation in pregnant women are effective in reducing the perception of labor pain and shortening the duration of the second stage of delivery. Therefore, we recommend breathing exercises as an effective modality for labor pain management and shortening the duration of labor. TRIAL REGISTRATION： This study i

相干多普勒测风激光雷达(CDWL)在大气探测中被广泛应用,但传统的CDWL因多比特采样导致原始采样数据难以保存。提出了一种基于单比特采样的CDWL方案,利用时间交织采样技术,等效构建高速单比特模数转换器,有效降低原始采样数据存储的难度,同时降低计算复杂度和功耗。通过连续观测实验对比单比特和多比特采样的CDWL的功率谱特征值,风速差异的均值在0.08 m/s以内,其标准差在0.86 m/s以内。实验结果表明,单比特采样可以保持CDWL的性能,同时有效地减少原始数据量,展示了其在CDWL应用中的潜力。

Creation of fermionic particles by a time-dependent electric field and a space-dependent magnetic field is studied with the Bogoulibov transformation method. Exact analytic solutions of the Dirac equation are obtained in terms of the Whittaker functions and the particle creation number density depending on the electric and magnetic fields is determined.

This paper firstly analyzes the Brexit’s impact on the US stock market using a novel interval methodology. The interval-valued dummy variables are proposed to measure the direction and magnitudes of the changes in the inter-day trend and the intra-day volatility of S&P500 returns simultaneously. It is found that both the trend and the volatility of S&P500 returns increased before the Brexit. Besides, the Brexit negatively affected S&P500 returns’ trend in the short term after the event,while its impact on market volatility was positive, which slowly decayed across time. Furthermore, a new interesting finding is that there are both short-term momentum effects(i.e., positive autocorrelation of trends) and volatility clustering in stock markets.
