目的分析药物涂层球囊(DCB)处理冠状动脉小血管狭窄病变的疗效和发生再狭窄的危险因素。方法回顾性分析该院2021年12月至2023年6月收治的160例存在冠状动脉小血管狭窄病变,行DCB经皮腔内冠状动脉成形术(PTCA)介入治疗患者的临床资料,术后6~12个月返院复查患者共90例。对比分析其中44例治疗后再狭窄患者(研究组)与46例治疗后未发生狭窄患者(对照组)的基本临床资料、血脂指标[总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、同型半胱氨酸(Hcy)、超敏C反应蛋白(hs-CRP)]水平及手术资料。结果2组患者在性别、年龄、吸烟史、肥胖、既往经皮冠状动脉介入手术(PCI)病史、高血压、糖尿病、慢性肾功能衰竭、甲状腺功能亢进、甲状腺功能减退方面比较,差异均无统计学意义(P>0.05);2组患者的TC、TG、HDL-C、LDL-C、Hcy、hs-CRP水平比较,差异均无统计学意义(P>0.05);2组患者DCB管径比较,差异有统计学意义(P0.05)。研究组患者冠心病家族史、未规范服药比例明显高于对照组,差异均有统计学意义(P<0.05)。经多因素logistic回归分析结果显示,DCB管径、冠心病家族史、未规范服药是DCB处理冠状动脉小血管狭窄病变发生再狭窄的独立危险因素(P<0.05)。结论DCB处理冠状动脉小血管狭窄病变时,DCB管径小(2.00~2.25 mm)则再狭窄率相对高。DCB管径小、冠心病家族史、未规范服药是DCB处理冠状动脉小血管狭窄病变发生再狭窄的独立危险因素。

Crop residue management affects both crop productivity and soil fertility as well as human and environmental health,thus playing a critical role in the sustainability of cropping systems.We conducted a meta-analysis to examine the effect of in situ retention of crop residues on rice yield in China,and evaluated their fertilizer value for rice production.Results indicated that overall,crop residue retention significantly increased rice yield by 5.2%in China.Spikelet number per panicle and grain weight showed significant positive responses to crop residue retention,whereas the number of panicles and the percentage of filled grains were not significantly affected.Yield gains under crop residue retention were lowest,but significant,at mean annual temperature of 11-15℃.Yield responses to crop residue retention were not significantly affected by soil N content,residue types (legume vs.non-legume),and tillage regimes(no-tillage vs.conventional tillage).Rice yield gains under crop residue retention increased with increasing experimental duration.Yield responses to crop residue retention increased when the proportion of inorganic N fertilizer applied in the vegetative stage increased from 70%to 100%.Compared to full rates of inorganic fertilization alone,rice yield was not adversely affected by crop residue retention with reduced rates of inorganic N,P,and K fertilizers by averages of 29.4%,8.3%,and 21.9%, respectively.Therefore,we conclude that crop residue retention can significantly increase rice yield and substitute a part of inorganic fertilizers,while the magnitude of yield gains and fertilizer reduction may be site-specific and depend on agronomic practices.

作者：薛奇戴庆平丁建夫武培怡 Department of Chemistry Nanjing UniversityNanjing.

The coordination polymerization of benzotriazole with metallic copper has been investigated by infrared and X-ray photoelectron spectroscopies. We found that benzotriazole could react with copper (0) under mild conditions to form bis (benzotriazolato) copper (Ⅱ) and benzotriazolato copper (Ⅰ)which covered the surface of copper metal in the shape of polymeric materials. Since benzotriazole is of great interest as a ligand in that its presence in many biological system with metal ions, and is considered as a corrosion inhibitor, this work will be in favour of the study of protective corrosion.

Background:Light at night(LAN)has become a concern in interdisciplinary research in recent years.This global interdisciplinary study aimed to explore the exposure-lag-response association between LAN exposure and lung cancer incidence.Methods:LAN data were obtained from the Defense Meteorological Satellite Program’s Operational Linescan System.Data of lung cancer incidence,socio-demographic index,and smoking prevalence of populations in 201 countries/territories from 1992 to 2018 were collected from the Global Burden of Disease Study.Spearman correlation tests and population-weighted linear regression analysis were used to evaluate the correlation between LAN exposure and lung cancer incidence.A distributed lag nonlinear model(DLNM)was used to assess the exposure-lag effects of LAN exposure on lung cancer incidence.Results:The Spearman correlation coefficients were 0.286-0.355 and the population-weighted linear regression correlation coefficients were 0.361-0.527.After adjustment for socio-demographic index and smoking preva-lence,the Spearman correlation coefficients were 0.264-0.357 and the population-weighted linear regression correlation coefficients were 0.346-0.497.In the DLNM,the maximum relative risk was 1.04(1.02-1.06)at LAN exposure of 8.6 with a 2.6-year lag time.After adjustment for socio-demographic index and smoking prevalence,the maximum relative risk was 1.05(1.02-1.07)at LAN exposure of 8.6 with a 2.4-year lag time.Conclusion:High LAN exposure was associated with increased lung cancer incidence,and this effect had a specific lag period.Compared with traditional individual-level studies,this group-level study provides a novel paradigm of effective,efficient,and scalable screening for risk factors.

为有效提高海参废弃物利用率,本文以海参肠废弃物为原料,采用热水提取法提取海参肠多糖,结合响应面法优化提取工艺并分析海参肠多糖理化性质。结果表明,海参肠多糖最优提取工艺条件为:提取时间1 h、提取温度80℃、料液比1:8(mg/mL)、重复提取2次,在此条件下多糖的平均得率为4.43%±0.17%。利用高效液相色谱法分析该条件下提取的多糖平均分子量为4.91×10^(6) Da。通过气相色谱法分析海参肠多糖主要由岩藻糖、甘露糖和阿拉伯糖组成,含有部分半乳糖和葡萄糖。采用热重分析仪研究热力学性质,发现温度在309℃时多糖结构发生崩解,在800℃时多糖重量损失为85.46%。运用扫描电子显微镜观察形貌结构,发现多糖表面是由不均匀椭圆形球状颗粒组成。以上结果初步揭示了热水提取海参肠多糖的特性,为海参废弃物资源利用提供了理论基础。

为探究含钙物质对酸性镉污染农田粉葛生长及镉富集特征,以江西省新余市酸性镉污染土壤为研究对象,研究了施用石灰和牡蛎粉2种钙素材料对土壤化学性质、粉葛各部位镉含量及生物量的影响。结果表明,与对照比,施钙(石灰、牡蛎粉)处理显著提高了土壤pH(0.85~0.87个单位),显著降低了土壤有效态镉含量(53.85%),施钙处理还降低了镉在粉葛体内富集。与对照相比,石灰处理粉葛总生物量、产量和收益分别增加了34.26%、38.20%和107.15%,块根和葛粉中镉含量分别降低了34.09%和15.38%。与对照相比,牡蛎粉处理粉葛总生物量、产量和收益分别增加了42.46%、38.07%和173.08%,块根和葛粉中镉含量分别降低了63.64%和69.23%,其中以牡蛎粉处理的增产降镉效果最佳。相关分析表明,粉葛生物量及产量与土壤pH呈显著正相关(P<0.05),与土壤镉含量呈显著负相关(P<0.05);粉葛各部位镉含量与土壤pH呈显著负相关(P<0.05),与土壤中镉含量呈显著正相关(P<0.05)。综上,在镉污染耕地上施用牡蛎粉(2250 kg·hm^(-2))更有利于促进粉葛的生长,提高粉葛产量、品质及收益,同时还能有效降低镉在粉葛体内的富集,实现粉葛安全生产。

【目的】镉(Cd)是一种有毒重金属,稻田Cd污染和稻米中Cd的积累已严重影响了现代农业高质量发展。研究不同土壤改良剂对南方Cd污染石灰性稻田中土壤Cd化学形态变化及水稻吸收积累Cd的影响,为选择适合修复南方石灰性稻田Cd污染的钝化材料和保障粮食安全生产提供理论依据。【方法】研究以Cd污染石灰性稻田为研究对象,通过大田原位修复试验,在等量氮磷钾养分投入条件下,研究了添加土壤调理剂(AF)、炭基微生物菌剂(CMF)和复合微生物肥+RBM微生物液体菌剂(RBM)对Cd污染稻田土壤化学性质、Cd形态含量变化以及水稻各部位Cd富集与转移的影响。【结果】施用土壤改良剂在一定程度上能保证水稻产量。与单施化肥处理相比,添加炭基微生物菌剂可以提高土壤有机碳含量,增幅为13.19%,而且施用土壤改良剂的处理均能增加土壤CEC,同时降低水稻成熟期土壤DTPA有效态Cd含量和土壤酸可提取态Cd含量,其中AF和CMF处理土壤酸可提取态Cd含量显著降低了8.84%和8.37%,促进了土壤Cd由活性强的形态向稳定态转化;通过BCR法分析土壤中Cd的4种化学形态发现,各处理土壤化学形态Cd含量大小均表现为残渣态>可还原态>酸可提取态>可氧化态;AF处理TF_(Leaf/Stem)降低了15.01%,而CMF和RBM处理TF_(Leaf/Stem)分别提高了15.14%和28.29%;此外,CMF处理水稻植株中TF_(Stem/Root)和TF_(Rice/Root)分别降低了29.61%和43.52%,进而导致施用土壤改良剂的处理糙米中Cd含量降幅为22.75%~26.98%。相关分析表明,土壤有机碳与可氧化态和残渣态Cd含量呈显著正相关,糙米Cd含量与土壤酸可提取态Cd含量和糙米Cd富集系数均呈显著正相关。【结论】Cd污染石灰性稻田中施用土壤调理剂、炭基微生物菌剂、复合微生物肥+RBM微生物液体菌剂主要是通过提高土壤有机碳和CEC达到削减Cd生物有效性的效果,进而减少了水稻植株对Cd的吸收,降低了Cd从水稻根系向地上部的转移。可以考虑采用炭基微生物菌剂和复合微生物肥修复Cd污染石灰性稻田,达到生态修复目标。
