Low-k and high aspect ratio blind through-silicon-vias （TSVs） to be applied in ＂via-last/backside via＂ 3-D integration paradigm were fabricated with polyimide dielectric liners formed by vacuum-assisted spin coating technique. MIS trench capacitors with diameter of-6 μm and depth of-54 μm were successfully fabricated with polyimide insulator step coverage better than 30%. C-V characteristics and leakage current properties of the MIS trench capacitor were evaluated under thermal treat- ment. Experimental results show that, the minimum capacitance density is around 4.82 nF/cm2, and the leakage current density after 30 cycles of thermal chock tests becomes stable and it is around 30 nA/cm2 under bias voltage of 20 V. It also shows that, the polyimide dielectric liner is with an excellent capability in constraining copper ion diffusion and mobile charges even un- der test temperature as high as 125℃. Finite element analysis results show that TSVs with polyimide dielectric liner are with lower risks in SiO2 interlayer dielectric （ILD） fracture and interfacial delamination along dielectric-silicon interface, thus, higher thermo-mechanical reliability can be expected.

Developing new polymeric semiconductors with excellent device performance is essential for organic electronics. Herein, we synthesized two new thiazoloisoindigo(Tz II)-based polymers, namely, P(Tz II-d Th-d Th) and P(Tz II-d Th-d Tz), by copolymerizing thiophene-flanked Tz II with bithiophene and bithiazole, respectively. Owing to the more electron-deficient nature of bithiazole than bithiophene, P(Tz II-d Th-d Tz)possesses deeper LUMO/HOMO levels of-3.45/-5.47 e V than P(Tz II-d Th-d Th)(-3.34/-5.32 e V). The organic field-effect transistor(OFET) devices based on P(Tz II-d Th-d Th) exhibited p-type behaviors with an average hole mobility value as high as 1.43 cm^(2)·V^(-1)·s^(-1), while P(Tz II-d Th-d Tz)showed typical ambipolar characteristics with average hole and electron mobilities of 0.38 and 0.56 cm^(2)·V^(-1)·s^(-1). In addition, we compared the performances of both polymers with other Tz II-based polymers reported in our previous work, and showed that the charge carrier polarity can be manipulated by adjusting the number of the thiophene units between the acceptor unit. As the increase of the number of thiophene rings,charge carrier polarity shifts from electron-dominated ambipolar transport to hole-dominated ambipolar transport and then to unipolar hole transport in OFETs, which provides an effective molecular design strategy for further optimization of polymer OFET performance.

针对地球红外辐射姿态测试方法中弹体表面红外辐射干扰较大的问题,建立旋转弹体自身红外辐射补偿模型,从而提高弹体姿态测量精度。首先,采用瞬态热平衡微分方程推导出旋转弹体表面温度变化曲线,获取弹体自身红外辐射亮度。然后,根据地球红外辐射及其在大气中的传播规律,建立了弹体自身红外辐射补偿数学模型。最终结合红外传感器输出和所推导的补偿模型,估算红外辐射补偿参数。结果表明补偿后姿态角解算误差显著降低,俯仰角和横滚角解算误差最终分别保持在±0.2°和±0.4°以内。本方法对姿态测量误差的减小具有显著效果,补偿方法简单有效,对旋转弹体的红外姿态测试技术的研究具有借鉴意义。

Background Chemokines and their receptors have been a research focus in transplantation immunology. Chemokines and their receptors play a role in lymphocyte recruitment and differentiation process. This study aimed to observe whether IL-4 and IL-10 may regulate the expression of chemokine receptors CCR3, CCR5 and CXCR3 on CD4^＋ T cells in CBA/J×DBA/2 mouse model and to explore the role of CCR3, CCR5, CXCR3 in immune tolerance in pregnancy. Methods The mouse model of spontaneous abortion （CBA/J×DBA/2） and the normal pregnant mouse model （CBA/J×BALB/c） were used. CBA/J×DBA/2 mice were injected with IL-4 （CBA/J×DBA/2-IL-4）, IL-4 and IL-10 （CBA/J×DBA/2-IL-4＋IL-10）, or normal saline （CBA/J×DBA/2-NS） as a control. The expression of CCR3, CCR5 and CXCR3 on CD4^＋ T cells from mouse peripheral blood was measured by the double-labelled FCM method, and the embryo resorption rate was also examined. Results The embryo resorption rate in the CBA/J×DBA/2 group without any treatment was significantly higher than that in the CBA/J×BALB/c group （17.9% vs 3.7%, P 〈0.01）. The embryo resorption rate in the CBA/J×DBA/2 group immunized with IL-4 or IL-4 together with IL-10 was significantly decreased, compared with that in the control and NS groups respectively. CCR3 expression on CD4^＋ T cells in the CBA/J×DBA/2 group without any treatment was significantly lower than that in the CBA/J×BALB/c group （0.3738±0.3575 vs 1.2190±0.2772, P 〈0.01）; both CCR5 （3.0900±1.5603 vs 1.2390±0.6361, P〈0.01） and CXCR3 （2.4715±0.9074 vs 0.9200±0.5585, P 〈0.01） expressions on CD4^＋ T cells of the CBA/J×DBA/2 group without any treatment were significantly higher than those of the CBA/J×BALB/c group. Significant up-regulation of CCR3 and down-regulation of CXCR3 were found in the CBA/J×DBA/2 group treated with IL-4 （CCR3： 2.0360±0.6944, CXCR3： 1.3510±0.5263, P〈0.01） or IL-4 and IL-10 （CCR3： 1.8160±1.0947, CXCR3：1.0940±0.7168, P〈0.01）. Because of the CCR5, IL-4 and IL-10 （1.9400±0.8504 vs 3.0900±1.5603, P 〈0.0

Objective To investigate the effect of FTY720-treated immature bone marrow-derived dendritic cells（BMDCs） on the embryo resorption rate in the CBA/J× DBA/2 abortion mouse *** The dendritic cells（DCs） were derived from bone marrow of DBA/2 mice, and then co-cultured with FTY720. The abortion mouse models were established by mating female CBA/J mice with DBA/2 mice. Via the CBA/J×DBA/2 abortion mouse model, six groups were established, group A： normal pregnancy model; group B： abortion mouse model with no treatment; group C： abortion mouse model injected with DC culture medium（DCCM）; group D： abortion mouse model injected with DC; group E： abortion mouse model injected with FTY720; group F： abortion model mouse injected with FTY720-DC. The differences were compared in the embryo resorption rates of the CBA/J ×DBA/2 abortion mouse model treated with FTY720-DC or different controls observed on gestation day 12 to 14, and then the microenvironment in murine pregnancy was *** The embryo resorption rate was statistically significantly decreased in group D and group E when they compared with group B and group C（P〈0.05, respectively）.Furthermore, the embryo resorption rate in group F showed a statistically significant decrease when compared with the other groups except group A（P〈0.01）. These resultssuggest that FTY720-DCs possess a notable advantage over DCs or FTY720 in reducing the embryo resorption rate of the abortion mouse model. The percentage of Th17（IL-17＋CD4＋T cells） in peripheral blood mononuclear cell（PBMC） in the abortion mouse model was 4.35%±0.34% before treated with FTY720-DC, and was1.34%±0.28% after treated with FTY720-DC（P〈0.01）. The percentage of Tregs（CD4~＋CD25~＋Foxp3~＋T cells） in PBMC was significantly increased in group F（8.35%±1.80%） as compared with group B（2.68%±0.65%）（P〈0.01）.Conclusion Adoptive transfer of FTY720-DC can statistically significantly reduce the embryo resorption rate in the CBA/J×DBA/2 abortion mouse model.

背景:在临床中不稳定型股骨转子间骨折应用股骨近端防旋髓内钉修复较为常见,而且修复效果较好,但是存在髋内翻畸形风险。反向倒置股骨远端微创内固定系统是一种最新的治疗方式,能够避免患者髋内翻畸形,但是目前关于两者的系统性比较研究很少。目的:比较股骨近端防旋髓内钉与反向倒置股骨远端微创内固定系统修复老年不稳定型股骨转子间骨折的临床疗效、并发症及关节功能的差异。方法:回顾性分析64例老年不稳定型股骨转子间骨折患者的临床资料,其中采用反向倒置股骨远端微创内固定系统治疗者28例,采用股骨近端防旋髓内钉治疗者36例,分别比较两组患者骨折愈合时间、负重时间、并发症及内固定后髋关节功能Harris评分等指标。结果与结论:倒置股骨远端微创内固定系统组较股骨近端防旋髓内钉组患者负重时间更早,而在骨折愈合时间、内固定后并发症发生率、髋关节功能Harris评分的比较中差异无显著性意义(P>0.05)。提示反向应用倒置股骨远端微创内固定系统修复老年不稳定型股骨转子间骨折的疗效和并发症与股骨近端防旋髓内钉相似,是一种固定可靠、并发症少的内固定方法。
