急性胆囊炎是常见的急腹症之一。近年来,随着微创技术的进步和外科医师腹腔镜水平的提升,腹腔镜下胆囊切除术已成为治疗急性胆囊炎的金标准,因其创伤小、操作简单、术后恢复快而备受推崇。但对于高龄、合并严重基础疾病的高危患者而言,...急性胆囊炎是常见的急腹症之一。近年来,随着微创技术的进步和外科医师腹腔镜水平的提升,腹腔镜下胆囊切除术已成为治疗急性胆囊炎的金标准,因其创伤小、操作简单、术后恢复快而备受推崇。但对于高龄、合并严重基础疾病的高危患者而言,急诊行LC存在着较高的手术风险。超声引导下经皮经肝胆囊穿刺引流术能够有效减轻胆囊压力、迅速缓解感染症状,目前已逐渐成为有手术禁忌的患者首选的治疗措施。本文对PTGBD的现状和问题进行综述,并对其未来前景进行讨论。Acute cholecystitis is one of the common acute abdominal diseases. In recent years, with the advancement of minimally invasive technology and the improvement of surgeons’ laparoscopic level, laparoscopic cholecystectomy has become the gold standard for the treatment of acute cholecystitis, which is highly respected because of its small trauma, simple operation, and fast postoperative recovery. However, for high-risk patients of advanced age and combined with severe underlying diseases, there is a high surgical risk of performing LC in emergency. Ultrasound-guided percutaneous transhepatic gallbladder puncture and drainage (PTGBD) can effectively reduce gallbladder pressure and rapidly alleviate the symptoms of infection, and has gradually become the preferred therapeutic measure for patients with contraindications to surgery. This article reviews the current status and problems of PTGBD and discusses its future prospects.展开更多
基于ROMS(the Regional Ocean Model System)模式,以等温线范围变化作为黄海冷水团范围变化的示性指标,采用谱分析及相关分析的方法,分析夏季黄海冷水团范围变化。结果表明:黄海冷水团范围的变化存在明显的年变化特征,与纬向风速和经向...基于ROMS(the Regional Ocean Model System)模式,以等温线范围变化作为黄海冷水团范围变化的示性指标,采用谱分析及相关分析的方法,分析夏季黄海冷水团范围变化。结果表明:黄海冷水团范围的变化存在明显的年变化特征,与纬向风速和经向风速相关,风速大则范围就大;黄海冷水团的范围还存在着5年的周期变化特征,其与ENSO现象相关;厄尔尼诺年时,滞后17个月的黄海冷水团的分布范围一般会较小;而拉尼娜年时,滞后17个月的黄海冷水团的分布范围会比较大。展开更多
