Appropriate materials collaborated with reasonable structure can significantly increase the separator performance for lithium-ion *** this work,taking the advantages of microfibrous and nanofibrous membranes and compensating for their defects,we developed a composited separator(GOPPH)with excellent overall performance by first wetting-modifying the polyethylene terephthalate microfibers and then laminating a polyvinylidene fluoride-hexafluoropropylene nanofiber *** a combination not only offers the GOPPH separator,from the perspective of structure,with high porosity and hierarchical structure in terms of fiber diameter and pore size,but also provides satisfactory features including wettability,mechanical strength and thermal shutdown function that benefit from the selected ***,as determined by experimental and theoretical approaches,the obtained GOPPH separator exhibits considerably enhanced lithium ion transport ability with a high lithium ion transference number and transport rate,which thereby endowing the cell with superior cycling stability with a capacity retention of 93%after 200 cycles at 1 ***,considering battery safety and performance,the GOPPH fibrous membrane could be a promising separator candidate for lithium-ion batteries.

选择壳寡糖(GT)和复合寡糖(KP)为制剂处理,以大棚常规对照(CG)和清水对照(CK)为对比,分析黄瓜叶片叶绿素相对含量(SPAD)、叶绿素荧光参数和超微结构,根系表观形态和根系活力(RV),以及抗氧化酶和内源激素的变化,比较不同类型寡糖制剂对设施黄瓜生长及产量的调控作用。结果表明:与其他处理相比,KP处理能有效促进黄瓜叶片和根系生长,其SPAD、最大光化学量子产量(Fv/Fm)、光化学淬灭系数(qP)、非光化学淬灭系数(NPQ)和RV均显著增加4.15%~15.63%、6.49%~20.03%、33.33%~152.63%、10.37%~71.62%和8.51%~171.43%;超氧化物歧化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CAT)活性显著提升6.75%~91.49%、3.85%~97.62%和3.00%~28.15%;此外,促使黄瓜生育后期叶片生长素(IAA)含量显著提高5.43%以上,脱落酸(ABA)含量显著降低4.35%~18.63%;黄瓜产量和可溶性糖含量显著增加13.72%和11.52%以上。比较而言,GT处理对黄瓜根冠生长,内源激素和抗氧化酶活性的影响表现出不稳定性,仅坐果期叶片光合生理特性(SPAD、叶绿素荧光参数和叶片超微结构)和RV有所改善。相较于GT处理,KP处理在促进黄瓜根冠生长,调控抗氧化酶活性和内源激素平衡方面具有明显优势。结合相关性分析发现,黄瓜产量与NPQ、RV、SOD和POD活性呈极显著正相关(P<0.01),与Fv/Fm显著正相关(P<0.05);且SOD和POD活性均与ABA含量显著负相关(P<0.05)。综上,外源复合寡糖主要通过促进黄瓜根冠协调生长,维持生育后期高光合效率、根系活力和叶片功能结构稳定,调节抗氧化酶活性,促进生长激素和抑制生长激素间的平衡,保障生育后期细胞膜功能稳定,延缓叶片自然衰老,实现黄瓜的提质增产。

“血不利则为水”出自《金匮要略》,是张仲景提出的一种关于血水之间病理关系的论述。瘀血阻滞是子宫腺肌病的核心病机,湿瘀互结型是其较为多见的临床证型。本文通过探讨血水之间互化互病的关系,以“血不利则为水”为切入点论治湿瘀互结型子宫腺肌病,提出瘀血是子宫腺肌病发病之源,瘀血阻滞进而引发津液运行代谢失常产生病理水湿,水湿停滞又加重瘀血的阻滞,瘀血与水湿互为因果、相互胶结而发病,故治疗应调治津血,可选择祛瘀与除湿并行的血水同治法,为子宫腺肌病的临床治疗提供理论依据。

AIM: To clarify the role of inducible nitric oxide synthase(i NOS) in blood-retinal barrier(BRB) injury after acute high intraocular pressure(IOP) in ***: Forty-two Sprague-Dawley(SD) rats were randomized into 7 groups [control(Cont), 3, 6, 12, 24, 48, and 72 h, n=6]. Except Cont group, other groups’ retina tissue was obtained at corresponding time points after a model of acute high IOP have been established in rats. The expression of i NOS and tight junction protein zonula occludens(ZO)-1 was detected by Western blotting. Evans blue(EB;3%) was injected into the great saphenous vein to detect the leakage of EB by spectrophotometer. Nine rats were divided into Cont, 6 h, 12 h groups, the expression of i NOS was localized by immunofluorescence. In order to verify the role of i NOS in the damage to BRB, thirty-six rats were randomly divided into 4 groups [Cont, Cont+inhibitor(Inh), 6 h and 6 h+Inh, n=9]. After treatment with the i NOSspecific inhibitor 1400 W, the expression of i NOS and ZO-1 and the leakage of BRB were detected ***: The immunofluorescence results showed that the expression of i NOS was observed in the Cont group and 6 h group, but not in the 12 h group. i NOS was mainly expressed in the retinal nerve fiber layer, ganglion cell layer and inner nuclear layer and that it did not colocalize with the retinal ganglion cell marker Neu N but was co-expressed with the vascular endothelial cell marker CD31. Western blotting showed that in the early period(3 h, 6 h) after acute high IOP, the expression of i NOS was upregulated, then the down-regulation of i NOS were tested in the follow-up timing spots. ZO-1 expression showed a continuous downregulation after 6 h. The quantitative results for EB showed that the amount of EB leakage began to increase at 3 h after acute high IOP. At 6 h, the leakage of EB was lower, but at 12 h, the leakage of EB was highest, after which it gradually recovered but remained higher than that in the Cont group. The
