Brazilian leading business magazine EXAME Editor-in-chief Lucas Amorim and Editor in macroeconomics Luciano Pádua recently talked about the cooperation between Brazil and China in an interview with China News Network as this year marks the 50th anniversary of the establishment of diplomatic relationship between the two countries.

Amorim mentioned that he had been to China four times and visited several Chinese technology companies. He noted that Chinese companies offer excellent products and technologies, with many already leading the Brazilian market in sectors including electric vehicles.

Pádua highlighted the challenges of cultural exchange between Brazil and China, stressing that promoting cultural exchange and mutual understanding between the two nations can strengthen cooperation between their peoples.(Gong Weiwei)

原标题:美商务部长定了他,将“领导”对华加税

用可乐治疗胃结石的机制是碳酸饮料能中和植物性胃结石中的鞣酸蛋白,两者能够产生化学反应,产物是二氧化碳+水+可溶性的鞣酸钠。二氧化碳具有一定的压力(压力大小取决于二氧化碳的量),压力产生渗透力及冲击力,能使胃结石表面及内部变得松软,从而裂解胃结石。而且,可乐中含有碳酸和磷酸,能够与胃结石中的钙等无机物结合,破坏结石的聚合物质。

“喝可乐化胃结石”适合哪些患者呢?这种方法适用于急性、松软的高鞣酸性胃结石,比如有山楂石、柿子石,且不合并胃溃疡的患者。该疗法对慢性胃结石、黑枣石治疗效果很差。黑枣石的硬度明显比山楂石、柿子石大,往往需要医生在胃镜下通过器械将其绞碎,然后经胃窦(胃的出口)排出,然后再结合药物溶石的方法来治疗。胃中结石质地坚硬、体积较大且经胃镜治疗失败的胃结石患者,以及合并消化道大出血、梗阻、穿孔的患者,应选择外科手术治疗。

胃结石最常见的危害是胃多发溃疡、胃黏膜多发糜烂及消化道出血。胃溃疡的形成主要是由于胃结石对局部黏膜造成刺激和损伤,也就是胃结石摩擦导致的物理性损伤。较大的石头会引起胃出口梗阻,而小的结石会通过胃出口进入小肠,有时会导致小肠梗阻,使患者出现腹痛、呕吐等症状。最严重的情况是胃穿孔、胃活动性出血或者腹膜炎等急腹症的出现。所以,胃结石患者要抓紧时间治疗,高危人群应重视预防和管理。
