Single phase lead titanate (PbTiO 3 ) was prepared by solid-state route using lead (II) oxide (PbO) and titanium dioxide (TiO 2 ) as precursors. The effects of using impact mill (IM) and ball mill (BM) in solid state reaction have been observed. X-ray diffraction (XRD) pattern was recorded at room temperature and analyzed by employing Rietveld method. X-ray diffraction (XRD) pattern shows that the PbTiO 3 particles are tetragonal with tetragonality (c/a) ratio ranging from 1.058 to 1.063 and average crystallite size from 40.8 to 64.2 nm. It is found that the impact mill (IM) can be used to produce pure tetragonal perovskite with a lower tetragonality and average crystallite size.

Meplazumab,a humanized CD147 antibody,has shown favourable safety and efficacy in our previous clinical *** DEFLECT(NCT04586153),167 patients with severe COVID-19 were enroled and randomized to receive three dosages of meplazumab and a *** at 0.12 mg/kg,compared to the placebo group,showed clinical benefits in significantly reducing mortality by 83.6%(2.4%vs.14.6%,p=0.0150),increasing the proportion of patients alive and discharged without supplemental oxygen(82.9%vs.70.7%,p=0.0337)and increasing the proportion of patients who achieved sustained clinical improvement(41.5%vs.31.7%).The response rate in the 0.2 mg/kg group was relatively increased by 16.0%compared with the placebo group(53.7%vs.46.3%).Meplazumab also reduced the viral loads and multiple cytokine *** with the placebo group,the 0.3 mg/kg significantly increased the virus negative rate by 40.6%(p=0.0363)and reduced IL-8 level(p=0.0460);the 0.2 mg/kg increased the negative conversion rate by 36.9%,and reduced IL-4(p=0.0365)and IL-8 levels(p=0.0484).In this study,the adverse events occurred at a comparable rate across the four groups,with no unexpected safety findings *** conclusion,meplazumab promoted COVID-19 convalescence and reduced mortality,viral load,and cytokine levels in severe COVID-19 population with good safety profile.

利用PS-TDP8插针式热扩散探针技术,在不同生长季节对吐鲁番盆地杏树树干液流变化进行监测,并同步记录果园气象因子,分析杏树树干液流变化规律,建立树干液流与环境因子之间的关系模型,为干旱地区杏高效、节水栽培提供依据。结果表明:吐鲁番盆地杏树树干液流速率日变化具有明显的昼夜变化规律,6、7月液流速率日变化峰值为最大,分别达到0.71、0.78 g·s^(-1);杏液流速率表现为晴天高于阴天,且晴天液流产生时间比阴天早1 h;夏季液流启动时间于07:30—08:00左右,比春季和秋季早1 h,并持续时间长,单位时间内的液流量大,这导致夏天杏树液流速率峰值最大,平均单位时间液流量、日平均液流量及月液流量均高于其他季节,分别为0.461 L·h^(-1)、11.062 L·d^(-1)、331.68 L·month^(-1)。气温、光照辐射和水汽压亏缺的变化规律与液流速率的变化规律基本上一致,呈现出极显著正相关关系(P<0.01);相对湿度的变化规律与杏树树干液流速率日变化规律相反,呈现出极显著负相关关系(P<0.01)。构建了杏树树干液流速率与环境因子的逐步回归模型,各方程均达到极显著水平,各月份决定系数R2均大于0.85以上,拟合良好。总之,吐鲁番盆地夏日光照辐射强,气温较高,夏季杏树液流量加快,蒸腾耗水量增加,因此夏季要及时灌溉,且灌溉时间宜选日出前或日落后,避免蒸发造成灌溉水损失。
