目的评价骶椎CT、MRI影像融合建模3D打印引导骶神经穿刺的安全性和有效性。方法前瞻性收集2016年7月至2017年8月间上海交通大学医学院附属仁济医院拟行骶神经调控术(SNM)的42例患者,采用随机数字表法将患者随机分为对照组(n=22)与试验组(n=20)。对照组采用传统的X线透视下十字定位法进行骶神经穿刺,试验组采用骶椎CT、MRI影像融合建模3D打印辅助骶神经穿刺。记录两组穿刺次数、穿刺成功所用时间、刺激器调试时间、刺激器最小起效电压、累计X线辐射剂量和术后疗效(二期转化)、并发症。通过两独立样本t检验或χ^(2)检验比较两组间的差异。结果试验组的穿刺次数、穿刺成功所需时间、术中刺激器调试时间、辐射剂量、最小起效电压均低于对照组(P<0.05)。对照组和试验组各有15例和16例患者完成二期转化,差异无统计学意义(χ^(2)=0.757,P=0.384)。对照组术后3例出现并发症,其中感染2例,出血1例,试验组未出现并发症。结论骶椎CT、MRI影像融合建模3D打印方法能安全引导SNM骶神经穿刺,相较于传统X线下透视穿刺定位法,能有效提高穿刺效率,减少术中辐射剂量。

A hybrid structure consisting of boron-doped porous carbon spheres and graphene （BPCS-G） has been designed and synthesized toward solving the polysulfide- shuttle problem, which is the most critical issue of current li-S batteries. The proposed hybrid structure showing high surface area （870 m^2.g^-1） and high B-dopant content （6.51 wt.%） simultaneously offers both physical confinement and chemical absorption of polysulfides. On one hand, the abundant-pore structure ensures high sulfur loading, facilitates fast charge transfer, and restrains polysulfide migration during cycling. On the other hand, our density functional theory calculations demonstrate that the B dopant is capable of chemically binding polysulfides. As a consequence of such dual polysulfide confinement, the BPCS-G/S cathode prepared with 70 wt.% sulfur loading presents a high reversible capacity of 1,174 mAh.g^-1 at 0.02 C, a high rate capacity of 396 mAh·g^-1 at 5 G and good cyclability over 500 cycles with only 0.05% capacity decay per cycle. The present work provides an efficient and cost-effective platform for the scalable synthesis of high-performance carbon-based materials for advanced li-S batteries.

The fluvial geochemistry of the mainstream and tributaries of the Zengjiang River was investigated,and the mass balance approach and deduction methods were used to estimate the uptake of atmospheric CO2 through rock chemical *** results showed that the chemical runoff mainly consisted of HCO3-,Ca2+,Na+,and dissolved Si,and that silicate mineral weathering was significant,but carbonate mineral weathering was a minor source of dissolved loads in the Zengjiang River basin because of the low amount of interlayered carbonate rock strata in the *** ion composition indicated that atmospheric CO2 was the primary erosive agent for rock chemical weathering in the Zengjiang River *** CO2 consumption fluxes caused by rock chemical weathering were(3.50-3.81) × 105 mol km-2 a-1,which is just lower than that in tropical and subtropical basalt and carbonate regions,and is much higher than that in temperate and cold-temperate regions,indicating that surficial chemical weathering processes in the humid and hot monsoon current influencing the low-middle latitude zone of the Northern Hemisphere constitutes a significant carbon sink in the global biogeochemical cycle.

目的:探讨脂蛋白α[Lp(α)]和循环氧化低密度脂蛋白(ox-LDL)在主动脉瓣钙化性疾病(CAVD)中的水平及临床意义。方法:选取2018年8月至2023年12月新乡医学院第一附属医院的55例CAVD患者(CAVD组)和41例无瓣膜病变患者(对照组)作为研究对象,通过双源CT检查将CAVD组分为3组:轻度钙化组、中度钙化组和重度钙化组。比较并分析治疗前CAVD组和对照组血清Lp(α)和ox-LDL水平;比较并分析轻度钙化组、中度钙化组和重度钙化组血清Lp(α)和ox-LDL水平;比较并分析治疗前后CAVD组患者血清Lp(α)和ox-LDL水平。采用Pearson相关分析血清Lp(α)和ox-LDL水平与Agatston积分的关系。结果:CAVD组患者的Lp(α)和ox-LDL水平[(409.20±134.55)mg/L、(49.44±16.02)ng/ml]明显高于对照组[(173.94±71.09)mg/L、(14.40±7.32)ng/ml,t=10.08、12.89,P<0.05]。重度钙化组患者的Lp(α)和ox-LDL水平[(566.81±47.19)mg/L、(68.31±7.05)ng/ml]明显高于中度钙化组[(410.57±76.29)mg/L、(50.07±6.96)ng/ml]和轻度钙化组[(259.08±54.99)mg/L、(30.88±6.37)ng/ml,t=7.05、7.72、16.67、15.54,P<0.05]。Pearson相关分析结果显示,CAVD患者血清Lp(α)和ox-LDL水平与Agatston积分呈正相关(r=0.73、0.75,P<0.05)。CAVD患者治疗后的Lp(α)和ox-LDL水平[(273.51±93.99)mg/L、(31.66±8.70)ng/ml]明显低于治疗前[(409.20±134.55)mg/L、(49.44±16.02)ng/ml,t=6.08、7.17,P<0.05]。结论:Lp(α)和ox-LDL参与CAVD的发展,其水平变化与疾病的严重程度密切相关,是早期诊断和监测评估主动脉瓣钙化性疾病的良好预测因子。
