Even though the relationship between antiarrhythmic drug usage and subsequent prostate cancer （PCa） risk has recently been highlighted, relevant findings in the previous literature are still inconsistent. In addition, very few studies have attempted to investigate the association between sodium channel blockers or potassium channel blockers for arrhythmia and the subsequent PCa risk. Therefore, this cohort study aimed to find the relationship between antiarrhythmic drug usage and the subsequent PCa risk using a population-based dataset. The data used in this study were derived from the Longitudinal Health Insurance Database 2005, Taiwan, China. We respectively identified 9988 sodium channel blocker users, 3663 potassium channel blocker users, 65 966 beta-blocker users, 23 366 calcium channel blockers users, and 7031 digoxin users as the study cohorts. The matched comparison cohorts （one comparison subject for each antiarrhythmic drug user） were selected from the same dataset. Each patient was tracked for a 5-year period to define those who were subsequently diagnosed with PCa. After adjusting for sociodemographic characteristics, comorbidities, and age, Cox proportional hazard regressions found that the hazard ratio （HR） of subsequent PCa for sodium channel blocker users was 1.12 （95% confidence interval [CI]： 0.84-1.50）, for potassium channel blocker users was 0.89 （95% CI. 0.59-1.34）, for beta-blocker users was 1.08 （95% Ch 0.96-1.22）, for calcium channel blocker users was 1.14 （95% Ch 0.95-1.36）, and for digoxin users was 0.89 （95% Ch 0.67-1.18）, compared to their matched nonusers. We concluded that there were no statistical associations between different types of antiarrhvthmic drug usage and subsequent PCa risk.

目的探讨一种结合血流储备分数(FFR)和冠脉造影图像评估冠状动脉微血管阻力的血流动力学新方法。方法入选2020年11月~2021年6月在空军军医大学西京医院行冠脉造影但无明显冠脉狭窄(FFR>0.8)或冠脉狭窄经PCI术治疗后FFR>0.8,且冠脉造影1月内行SPECT静息心肌灌注显像检查的患者。共纳入33例患者,35支血管。基于目标血管分区总评分(summed rest score of target vessel,SRSTV)将患者分为心肌灌注正常组(SRSTV≤1,n=21)和心肌灌注异常组(SRSTV>1,n=12)。35支血管中,SPECT静息心肌灌注正常组23支,异常组12支。通过多角度造影图像重建目标血管三维模型,基于FFR测量静息态和充血态的远近端压力,采用血流动力学方法分别计算目标血管对应血流量Q,并进一步计算微血管阻力R、归一化微循环阻力指数Rn、冠状动脉血流储备(CFR)和冠状动脉阻力储备(RRR)。比较两组间上述血流动力学参数的差异。结果两组患者年龄、性别、BMI、收缩压、舒张压、心率、住院天数、吸烟史、饮酒史、高血压、糖尿病史、心律失常史心、肌梗死史、脑血管病史、PCI史、CABG史、心血管病家族史、LVEF及用药史均无统计学差异。充血态条件下,归一化微血管阻力指数Rn在SPECT静息心肌灌注正常组和异常组间存在统计学差异,正常组显著低于异常组(P<0.01),但在静息态条件下,Rn在两组间差异不显著。其它项目两组间有数值上差异,无统计学意义。Spearman相关分析显示:微血管阻力R与SRSTV并无显著相关性,但归一化微血管阻力指数Rn在充血态与SRSTV呈现强相关关系(rho=0.602,95%CI:0.336~0.779,P<0.01),在静息态与SRSTV呈现弱相关关系(rho=0.335,95%CI:0.002~0.601,P<0.05),而CFR、RRR与SRSTV间均无显著相关性。结论在排除心外膜大血管功能学阻塞的患者中,结合FFR和冠脉造影图像的充血态归一化微循环阻力指数可很好区分心肌供血状态,为精准评估冠状动脉微血管阻力提供一种新的技术手段。

Nanocrystalline cellulose(NCC) was produced from rice husk biomass(Oryza sativa) by a chemical extraction process to explore the potential aspect of agro-waste biomass in Australia. In this work, the delignified rice husk pulp(D-RHP) was produced by alkaline delignification of raw rice husk biomass(R-RHB) using 4 mol·L^(-1) alkali solutions(Na OH) in a jacketed glass reactor under specific experimental conditions. D-RHP was bleached using 15% sodium hypochlorite, and the bleached rice husk pulp was coded as B-RHP. Finally,raw suspension of NCC was produced by the acid hydrolysis of B-RHP using 4 mol·L^(-1) sulphuric acid. The raw suspension of NCC was neutralized by a buffer solution and analyzed by TAPPI, FT-IR, XRD, SEM, AFM, and TEM. FT-IR spectra of NCC are different to R-RHB but similar with B-RHP and D-RHP. From XRD results, the crystallinity of NCC was found to be approximately 65%. In AFM analysis particle thicknesses have been confirmed to be in the range of(25 ± 15.14) nm or(27 ± 15.14) nm which is almost the same. From TEM analysis particle dimensions have been confirmed to be in the range of(50 ± 29.38) nm width and(550 ± 302.75) nm length with the aspect ratio ~ 11:1(length/diameter) at a 500 nm scale bar. On the other hand, at a 200 nm scale bar the particle dimensions have been confirmed to be in the range of(35 ± 17) nm width and(275 ± 151.38)nm length with the aspect ratio ~ 8:1. The aspect ratio of individual crystalline domain was determined in TEM analysis which is 10:1(100/10). Therefore the aspect ratios and dimensions of nanoparticles in NCC suspension are almost the same and in nano-meter scale, as confirmed from both AFM and TEM results. The yield of NCC from B-RHP was found to be approximately 95%, and the recovery of cellulose from R-RHB is about 90%.

Prior studies suggested that the use of androgen deprivation therapy （ADT） in patients with prostate cancer （PC） might cause the impairment of cognitive function which is one of the common symptoms of dementia; however, the association between ADT and cognitive impairment still remains controversial. This retrospective cohort study aimed to investigate the relationship between ADT and subsequent risk of dementia using a population-based dataset, Data for this study were taken from the Taiwan （China） Longitudinal Health Insurance Database 2005. We included 755 PC patients who received ADT in the study cohort and 559 PC patients who did not receive ADT in the comparison cohort. Each patient was individually tracked for a 5-year period to define those who subsequently received a diagnosis of dementia. Results show that the incidence rates of dementia per 100 person-years were 2.35 （95% confidence interval [95% CI]： 1.82-2.98） and 1.85 （95% Ch 1.35-2.48） for PC patients who received ADT and those who did not receive ADT, respectively. The adjusted hazard ratio （HR） for dementia for PC patients who received ADT was 1.21 （95% Ch 0.82-1.78, P = 0,333） compared to those who did not receive ADT. In addition, the adjusted HRs for dementia for PC patients receiving ADT with gonadotropin-releasing hormone （GnRH） agonists and without GnRH agonists were 1.39 （95% Ch 0.80-2.40, P = 0.240） and 1.13 （95% CI： 0.75-1.71, P = 0.564）, respectively, compared to PC patients not receiving ADT. We concluded that there was no difference in the risk of subsequent dementia between PC patients who did and those who did not receive ADT.

Graphene nanoplatelets （GNPs） were used as multifunctional nanofiller to enhance thermal and mechanical properties as well as electrical conductivity of two different biodegradable thermoplastics： poly lactide （PLA） and poly （butylene adipate-co-terephthalate）（PBAT）. Morphological investigations showed different levels of GNP dispersion in the two matrices, and consequently physical properties of the two systems exhibited dissimilar behaviours with GNP incorporation. Crystallinity of PLA, determined from differential scanning calorimetry, was observed to increase markedly with addition of GNPs in contrast to the decrease in crystallinity of PBAT. Isothermal and non-isothermal thermogravimetric analyses also revealed a more significant delay in thermal decomposition of PLA upon addition of GNPs compared to that of PBAT. Furthermore, results showed that increasing GNP content of PLA and PBAT nanocomposites influenced their Young＇s modulus and electrical conductivity in different ways. Modulus of PBAT increased continuously with increasing GNP loading while that of PLA reached a maximum at 9wt% GNPs and then decreased. Moreover, despite the higher conductivity of pure PBAT compared to pure PLA, conductivity of PLA/GNP nanocomposites overtook that of PBATIGNP nanocomposites above a certain GNP concentration. This demonstrated the determining effect of nanoplatelets dispersion state on the matrices properties.
