AIM: To investigate the early outcomes of vision, objective visual quality and their correlation after cataract surgery with trifocal intra.cular lens ***: The visual examination and objective visual quality analysis using Optical Quality Analysis System(OQAS) at 1 mo and 3 mo, and defocus curve examination at 3 mo were performed in 20 patients(27 eyes) after phacoemulsification combined with trifocal intra.cular lens implantation ***: The uncorrected distant(UD), intermediate and near visual acuity(va. were significantly improved after surgery(Pva.at 1 mo after the surgery was slightly better than that after 3 mo(P=0.026). The defocus curve after 3 mo indicated that the peak of distant vision was close to 0 logma., and UDva.was lower than 0.3 logma. in the range of-1.5 D to-3.0 D. The modulation tra.sfer function(MTF) cutoff frequency, strehl ratio(SR), Optical Quality Analysis System va.ues(OVs), includes OV100, OV20 and OV9 after the surgery were significantly better than before surgery(Pva.at 3 mo after the surgery had correlations with MTF cutoff, OSI, OV100 and OV20(r=-0.400, 0.431,-0.437,-0.411, P=0.039, 0.025, 0.023, 0.033). The uncorrected intermediate va.after 3 mo of the surgery had correlations with OSI and OV100(r=0.478,-0.411, P=0.012, 0.033). CONCLUSION: Trifocal intra.cular lens implantation can provide good distant, intermediate and near va. and the vision shows a well correlation with objective visual quality during early surgery.

为分析和挖掘西藏地区油菜籽特征品质,推动西藏油菜高质量发展,选取31份西藏地区与448份长江流域代表性油菜籽样品,分析了油菜籽含油量、脂肪酸和植物甾醇含量,比较了西藏地区与长江流域油菜品质差异。结果发现西藏油菜籽含油量显著高于长江流域冬油菜区,但植物甾醇含量显著低于长江流域冬油菜区。考虑到油菜籽中甾醇含量与芥酸含量呈负相关,在西藏地区取低芥酸油菜籽样品,验证了芥酸含量高是导致西藏地区油菜籽甾醇平均含量低于长江流域的重要原因,并筛选出含油量高于长江流域平均值,甾醇含量高的油菜籽品种新油20、清湘油168、新油17和藏油12号,可作为高甾醇油菜品种在西藏地区推广,对提升西藏地区油菜籽品质、巩固脱贫成果具有重要意义。

Multifactors have been reported to affect the gut microbiome, including genotype, age, diet, and ***, few reports have investigated the relative capacity of different factors to shape the gut microbiome in a single study. Our design used a genetic vitamin A-deficient mouse model, the Rbp4^(-/-)mouse,feeding with the low vitamin A diets at different ages of initiation(4 or 7 weeks) for 28 days. Fecal samples were collected for bacterial profiling at seven time points after diet controlling. With Rbp4 depletion,Akkerma.sia decreased and Bacteroides increased, whereas Desulfovibrio, Barnesiella, Clostridium_Xl va.and Lactobacillus fluctuated. The bacterial community swiftly adjusted with the vitamin A-deficient diet administra.ion and gradually changed(e.g., decrease of Barnesiella and increase of Desulfovibrio). Age exerted a relatively weaker but long-last influence. At an earlier age to feed a vitamin A-deficient diet, a higher microbial dysbiosis index will be va.ued. Of note, the shaping effects of diet and age on the bacterial community va.ied with the difference of genotype, which might indicate a greater role of genotype than diet and age in shaping the gut microbiome.

In this paper, for time-to-event data, we propose a new statistical framework for casual inference in eva.uating clinical utility of predictive bioma.kers and in selecting an optima. treatment for a particular patient. This new casual framework is based on a new concept, called Bioma.ker Adjusted Treatment Effect （BATE） curve. The BATE curve can be used for assessing clinical utility of a predictive bioma.ker, for designing a subsequent confirma.ion trial, and for guiding clinical practice. We then propose semi-p^rametric methods for estima.ing the BATE curves of bioma.kers and establish asymptotic results of the proposed estima.ors for the BATE curves. We also conduct extensive simulation studies to eva.uate finite-sample properties of the proposed estima.ion methods. Finally, we illustra.e the application of the proposed method in a real-world data set.

International Journal of Ophthalmology(English edition) 2018年第7期11卷 1222-1226页

作者： Ying-Jie ma.Bo Yu Yun-Hai Tu Bang-Xun ma. Xin-Yi Yu Wen-Can Wu Eye Hospital of Wenzhou Medical University Wenzhou 325000 Zhejiang Province China Department of Orbital and Oculoplastic Surgery Eye Hospital of Wenzhou Medical University Wenzhou 325000 Zhejiang Province China

AIM： To investigate a possible correlation between visual acuity（va. prognosis and the presence at baseline of va.ious orbital and ocular signs in patients affected by indirect tra.ma.ic optic neuropathy（ITON）. METHODS： From July 1 st, 2012 to July 1 st, 2015, 224 adults diagnosed with ITON who underwent endoscopic tra.sethmosphenoid optic canal decompression（ETOCD） were reviewed. Visual outcome before and after treatment were taken into comparison. RESULTS： Accompanied older in age, longer time to medical treatment and existence of optic canal fracture（OCF） were the independent predictors for poor postoperative va.and lower improvement degree of visual acuity（IDva., while worse preoperative va.was predictive factor for poor postoperative va.only. Mean va.ue of IDva.in patients with OCF was 0.19±0.30. Mean va.ue of IDva.in patients without OCF was 0.29±0.35. IDva.in cases without OCF was significant higher than those with OCF（t=2.272, P〈0.05）. CONCLUSION： Patients suffered from ITON without OCF before ETOCD have better surgical outcome than those with OCF. Older in age, longer time to medical treatment and existence of OCF are independent factors for poor va.prognosis and lower IDva. Preoperative va.is independent factor for va.prognosis only.
