A novel soluble π-conjugated polymer, poly[(3-octanoylpyrrole-2,5-diyl)-p-(N,N-dimethylamino)benzylidene](POPDMABE), was synthesized firstly by the condensation of 3-octanoylpyrrole with para-dimethylaminobenzaldehyde. The chemical structure of the polymer was characterized by FTIR and 1H NMR spectrometries. The polymer is a potential nonlinear optical(NLO) material. According to the function of optical forbidden band gap(E_g) and photon energy(hν), the optical forbidden band gaps of the polymer before and after ion implantation were calculated. The resonant third-order nonlinear optical properties of POPDMABE before and after ion implantation were also studied by using the degenerate four-wave mixing(DFWM) technique at 532 nm. When the energy is 25 keV and the dose is 2.2×10 17 ions/cm 2, the {polymer′s} optical forbidden band gap is about 1.63 eV which is smaller than that of the non-implanted sample(1.98 eV) and the resonant third-order NLO susceptibility of POPDMABE is about 4.3×10 -7 esu, 1 order of magnitude higher than that of the non-implanted sample(4.1×10 -8 esu). The results show that nitrogen ion implantation is an effective method to improve the resonant third-order NLO property of the polymer.

Nonvalvular atrial fibrillation (NVAF) is the most common sustained cardiacarrhythmia in clinical practice, which if untreated results in a doubling of cardiovascularmorbidity and mortality. AF is an independent predictor of stroke, with an annual risk 5 to 6 timeshigher than patients in sinus rhythm. During recent years, several randomised clinical trialsconducted by investigators around the world involving 13 843 participants with NVAF havedemonstrated convincingly the value of warfarin therapies for stroke prevention in high riskpatients. However, the dose response of warfarin is complex and its activity is easily altered byconcurrent medications, food interactions, alcohol and illnesses. Adherence to medical advice androutine monitoring of the international normalized ratio (INR) is important, because lowanticoagulant intensity predisposes the patients to thromboembolic complications and high intensityto haemorrhage. Studies suggested that anticoagulant clinics could improve the quality ofanticoagulation control, and anticoagulant clinics are common in western countries. However, inChina, most AF patients taking warfarin usually attend the outpatient clinic of cardiology, whilethe quality of anticoagulation control is never investigated. We therefore assessed anticoagulationcontrol in the outpatient clinic of cardiology, and the quality of anticoagulation control since theestablishment of anticoagulant clinics.

Background Delayed cure had been observed in recurrent cases after indexablation of atrial fibrillation ( AF) , however, its mechanism and incidence have not beenelucidated in detail. This study aims to investigate the impact of different ablation strategies onthe incidence of delayed cure and its possible mechanisms after trans-catheter ablation of *** One hundred and fifty-one consecutive cases with highly symptomatic, drug refractory AF wereincluded in this study [M/F = 109/42, mean age (56. 0 ± 11. 2) (18 -79) years]. Segmentalpulmonary vein ablation (SPVA) was performed in 83 patients with the guidance of circular mappingcatheter (SPVA Group) , circumferential PV linear ablation ( CPVA) was carried out in the rest 68cases under the guidance of 3 dimensional mapping system in conjunction with circular mappingcatheter ( CPVA Group). Delayed cure was defined as that early recurrence of atrial tachyarrhythmias( AF, atrial tachycardia, or atrial flutter) after ablation procedure was no longer observed duringsubsequent follow-up, and stable sinus rhythm was maintained ≥ 2 months. Results Early recurrenceof atrial tachyarrhythmias was detected in 41 cases from SPVA group and 23 cases from CPVA group,and delayed cure occurred in 21. 9% (9/41 ) of the cases from SPVA group and 47. 8% (11/23) of thecases from CPVA group, more delayed cure in later group was observed (P < 0. 05 ) . Meanwhile,patients in SPVA group took a longer time to achieve a delayed cure [ (27. 0 ± 18. 0) days vs (14.0 ±8. 1) days, P <0. 05] , and presented more recurrent episodes [ (3. 50 ± 1. 08) times a week vs(2.42 ± 1. 11) times a week, P <0. 05]. However, recurrent episodes after index ablation weremarkedly decreased in cases with delayed cure from both groups ( P < 0. 05). Conclusions Despite ofan early recurrence of atrial tachyarrhythimas after index ablation of AF, delayed cure occurs in asignificant number of patients undergoing either SPVA or CPVA. However, different ablationstrateg

为探讨万寿菊类胡萝卜素降解过程中CCD4b的功能,以万寿菊(Tagetes erecta L.)‘Scarletade’品种舌状花为试材,利用同源基因克隆获得CCD4b,命名为TeCCD4b (GenBank:KY450708)。序列分析表明TeCCD4b cDNA全长为1 725bp,编码区长度1 392bp,所编码的产物含463个氨基酸,主要定位于质体膜,属RPE65超家族,包含CCD家族保守的结构域;同源分析表明TeCCD4b与向日葵HaCCD4-L、案头菊CmCCD4b同源性最高;系统进化树分析显示TeCCD4b与HaCCD4-L和CmCCD4b亲缘关系最近,与其他物种的CCD4和CCD4a存在差异,表明TeCCD4b在进化过程中保守性不强,不同种属之间具有明显差异,基本符合植物的进化规律;荧光定量PCR结果显示TeCCD4b在舌状花发育过程中均有表达,且与万寿菊花色变化基本一致,表明万寿菊舌状花颜色变化可能与TeCCD4b表达量高低相关。

由乡村到城市是中国内地社会转型的基本方式,而且这一方式在近些年来城市盲目扩展的大环境下,变得更为迅猛与无序,其直接后果就是问题成堆,尤其是"城中村"、城郊失地农民的生计着落。这一问题解决不好,城市化进程将会举步维艰。研究借助南宁市郊留肖壮族新村案例,讨论了城郊失地农民生计"内卷化"之成因,并从政府、城市居民、失地农民三个维度提出了调适策略。
