目的:调查深圳地区乳腺癌术后患者的义乳佩戴情况,探讨影响义乳佩戴质量相关因素,为制定有效的护理决策提供依据。方法:通过“汝康云”乳腺癌康复俱乐部平台,采取网络微信调查问卷的形式,对2012年5月至2020年5月期间119例乳腺癌改良根治术后患者佩戴义乳相关认知内容进行调查,并分析调查的结果。结果:79.83%乳腺癌患者知道义乳的存在,52.10%患者有获取义乳佩戴的途径。80.00%的患者认为义乳可以改善形体缺失,达到美观作用;61.05%的患者认为可维持身体平衡;47.37%的患者认为还可保护胸部。半数以上(52.10%)的患者有佩戴义乳的需求,能够接受的义乳价位主要集中在>200~≤500元之间。结论:义乳佩戴的宣传力度不够、患者对义乳作用认识不全、患者对义乳佩戴需求差异可能是影响义乳佩戴的关键因素。

To explore fertilization methods for wine bamboo cultivation in southwestern semi-arid areas of China, this study analyzed annual changes in sap yield and nutrient composition from May 2013 to March 2015 by using bamboo charcoal-based bio-fertilizer （ZT） and organic fertilizer treatments （CK）. The study also provided basic data for functional beverage preparation and for application of ZT. The results of the two experimental cycles revealed that under the ZT treatment, sap was available for collection from May, the beginning of the rainy season, to November, the beginning of the dry season. The period of abundance was July to October with the highest yield of sap of 3.18 L stalk-1 in September, 2014, still lower than the moso bamboo sap, which was likely due to the scale of sap production of monopodial bamboos being different from that of sympodial bamboos. In January, trace amounts of sap were still detected, suggesting that the effect of the treatment was significant. Moreover,in the dry season, soil water content and soil temperatures at 10-15 cm depths indicated that the fertilizer had the ability to maintain soil temperatures and moisture. In both fertilizer treatments, the correlation between the collected sap and environmental parameters was significant. In the ZT treatment for the entire 2 years, the effectual environ- mental factors were soil water at 10-15 cm, air tempera- tures, and wind speeds. The same determining factors were observed for the rainy season. In the CK treatments, the effectual environmental factors for the entire year and the rainy season were soil water at 0-5 cm and air moisture. The bamboo charcoal-based bio-fertilizer elevated the potassium, calcium, iron, manganese, copper, and total phosphorus content, simultaneously increasing the sap yield, protein and reducing sugar contents, and with a relative increase in sap pH. The wine bamboo sap con- tained 18 amino acids. Glutamic acid, alanine and proline were the most abundant. Compared to the controls, the treatment showed higher le

Hydrogen is known for its elevated energy density and environmental compatibility and is a promising alternative to fossil fuels.Alkaline water electrolysis utilizing renewable energy sources has emerged as a means to obtain high-purity hydrogen.Nevertheless,electrocatalysts used in the process are fabricated using conventional wet chemical synthesis methods,such as sol-gel,hydrothermal,or surfactantassisted approaches,which often necessitate intricate pretreatment procedures and are vulnerable to post-treatment contamination.Therefore,this study introduces a streamlined and environmentally conscious one-step potential-cycling approach to generate a highly efficient trimetallic nickel-iron-copper electrocatalyst in situ on nickel foam.The synthesized material exhibited remarkable performance,requiring a mere 476 mV to drive electrochemical water splitting at 100 mA cm^(-2)current density in alkaline solution.Furthermore,this material was integrated into an anion exchange membrane watersplitting device and achieved an exceptionally high current density of 1 A cm^(-2)at a low cell voltage of2.13 V,outperforming the noble-metal benchmark(2.51 V).Additionally,ex situ characterizations were employed to detect transformations in the active sites during the catalytic process,revealing the structural transformations and providing inspiration for further design of electrocatalysts.

Climate data during 1971-2010 showed that mo st areas of Qinghai-Tibet Plateau showed warm wet climate change type dominated by temperature and humidity increase.Temperature increase magnitude was the smallest in spring and the largest in winter,and the precipitation increased at the low-altitude area and decreased at high altitude.The warm wet climate change caused Qinghai-Tibet Plateau alpine grassland degradation,reduction of glacier and frozen soil,wetland reduction and other environmental problems.

The frequency and T-cell receptor beta-chain variable （TCRBV） patterns of peripheral CD4＋CD25＋ regulatory T-cells （Tregs） are ambiguously altered in chronic hepatitis B （CHB） patients following tenofovir disoproxil fumarate （TDF） treatment. Moreover, the clinical significance of these parameters in relation to hepatitis B e antigen （HBeAg） seroconversion （SC） is largely unknown. In this study, the circulation of Tregs in HBeAg-positive CHB patients was determined by flow cytometry, and the molecular profiles of frequent TCRBV patterns of Tregs were analyzed using a gene melting spectral pattern. The parameters, such as Treg frequency, the number of skewed TCRBV patterns, hepatitis B virus （HBV） DNA levels, and alanine aminotransferase （ALT） levels, were analyzed by comparing their associations in seroconverting and non-seroconverting patients following TDF treatment. The Treg frequency was significantly correlated with the ALT level in seroconverting but not in non-seroconverting patients. Similarly, skewed TCRBV patterns were remarkably associated with HBV DNA levels in the SC group. Six TCRBV families （BV3, BV11, BV12, BV14, BV20, and BV24） were more prevalent than other TCRBV members in seroconverting patients pretreated with TDF, while BV12, BV15, and BV22 were predominant in non-seroconverting patients during TDF treatment. Taken together, the preferential TCRBV patterns may be associated with immune responses related to SC. The dynamic frequency and skewed TCRBV patterns of peripheral Tregs could contribute to predicting SC in CHB patients. Moreover, the conserved TCRBV complementarity-determining region （CDR3） motif may be targeted to develop personalized immunotherapy for CHB patients.

湟水流域是河湟谷地重要的组成部分,协同环境因素预测土壤养分空间分布对农业土壤养分管理尤为重要。土壤养分反演研究中对于参数对模型结果的影响和模型适用性的研究较少。选取研究区地形因子、土壤pH及光谱反射率共28个因子,结合贝叶斯优化算法构建人工神经网络(ANN)、支持向量机(SVM)和极端梯度提升(XGBoost)3种机器学习模型预测耕地土壤养分空间分布,计算决定系数(R2)、均方根误差(RMSE)和相对分析误差(RPD)评价3种模型的精度。结果表明:(1)基于贝叶斯优化超参数的XGBoost模型对全氮(TN)含量预测精度优于其他模型(R2=0.893,RMSE=0.359,RPD=2.470),预测土壤有机质(SOM)、速效磷(AP)和速效钾(AK)含量时,XGBoost模型验证集R2分别为0.801、0.509、0.442。(2)对比3种模型的寻优次数和误差发现,BOA-XGBoost模型参数优化次数少、效率高,具有更好的鲁棒性。对于不同的养分,ANN和SVM模型预测精度存在差异,SVM模型预测SOM含量时精度更高(RPD=1.580),而ANN模型预测TN时精度最佳(RPD=2.460)。基于贝叶斯算法进行超参数优化构建的XGBoost模型预测精度高,可以达到良好的预测效果,可为湟水流域精准农业施肥提供参考。

枸杞产业已成为青藏高原的优势产业,但存在氮肥利用率低、环境污染等问题。适当施用氮肥和硝化抑制剂是减少氮肥气态损失、提高氮肥利用率和降低温室气体排放的有效途径。为探讨枸杞栽培的适宜施肥方式,于2020年在柴达木盆地青海诺木洪农场,以11年生宁杞1号为试验材料开展田间试验,设置4个处理:N267、N133处理分别施用纯氮267、133 kg·hm^(-2),N267I1.33、N133I0.67处理分别在N267、N133处理施氮量的基础上配施硝化抑制剂—2-氯-6(三氯甲基)-吡啶(nitrapyrin)1.33、0.67 kg·hm^(-2),研究施氮量和2-氯-6(三氯甲基)-吡啶对施用的15N-尿素在枸杞-土壤系统去向的影响。结果表明,N267I1.33处理枸杞全株的干物质量、吸氮量和植株15N累积量(Ndfa)均最高,较N267处理分别提高了25.04%、30.17%、1.96%。秋果期及休眠前期N267I1.33处理的0~200 cm土层15N残留量较其他处理分别增加了73.89%~122.47%、80.33%~165.86%。N267处理的15N损失率最高,较N267I1.33处理提高了4.25个百分点,N133I0.67处理的15N损失率最低,较其余处理降低了2.08~10.29个百分点。N267I1.33处理的总产量最高,较其他处理提高了5.00%~9.48%。综上,267 kg N·hm^(-2)配施2-氯-6(三氯甲基)-吡啶1.33 kg·hm^(-2)可提高枸杞产量、植株吸氮量和土壤氮残留量,相同施氮量配施硝化抑制剂有利于提高枸杞生育后期土壤中的15N-尿素残留量进而降低土壤氮损失,是提高柴达木地区高肥力枸杞园氮肥利用率的推荐组合。本研究结果可为柴达木地区枸杞合理施肥提供科学依据。
