目的探讨腹腔镜食管裂孔疝修补术联合改良DOR胃底折叠术治疗食管裂孔疝（HH）合并胃食管反流病患者的临床疗效。 方法选择2016年1月至2019年1月河北北方学院附属第二医院收治的108例食管裂孔疝合并胃食管反流病患者开展回顾性研究，按照不同手术方式将患者分为2组，每组患者54例。对照组行常规开腹手术，联合组行腹腔镜食管裂孔疝修补术联合改良DOR胃底折叠术，比较2组患者术前及术后6个月反流时间、反流次数、DeMeester评分、食管下括约肌压力及Gerd Q量表评分。 结果2组术前反流时间、反流次数、DeMeester评分、食管下括约肌压力及Gerd Q量表评分比较，差异无统计学意义（P>0.05）；2组患者术后6个月反流症状与术前比较，均得到明显改善，差异有统计学意义（P<0.05）；2组术后反流时间、反流次数、DeMeester评分、食管下括约肌压力及Gerd Q量表评分比较，差异有统计学意义（P<0.05）。联合组患者的手术时间、术中出血量及术后住院时长均明显优于对照组，差异有统计学意义（P<0.05）。 结论腹腔镜食管裂孔疝修补术联合改良DOR胃底折叠术对HH合并胃食管反流病患者效果显著，有利于患者身体快速恢复，微创、安全且近期疗效满意。     

旋覆代赭汤对反流性食管炎大鼠模型TLR4/NF-κB的影响

目的观察旋覆代赭汤对反流性食管炎(RE)模型大鼠食管黏膜与脂多糖(LPS)、Toll样受体4(TLR4)、核因子κB(NF-κB)表达的影响。方法将60只雄性Wistar大鼠按随机数字表法分为正常对照组、模型组、旋覆代赭汤组(简称中药组,9.89 g/kg)、西药(奥美拉唑+莫沙比利,2.58 mg/kg)组,每组15只。除正常对照组外大鼠采用“4.2 mm幽门夹+2/3胃底结扎术”制备酸碱混合反流RE大鼠模型。术后第7天予相应药物干预,持续干预14天。利用光学显微镜观察大鼠食管下段黏膜组织形态学变化;应用ELISA法检测定外周血中LPS含量;采用Western Blot法与RT-PCR法检测食管黏膜组织中TLR4、NF-κB蛋白和基因表达。结果与正常对照组比较,模型组大鼠食管黏膜镜下损伤最为严重,食管黏膜呈炎性改变,可见急慢性炎细胞浸润,病理积分和外周血中LPS含量升高(P<0.05),食管组织中TLR4、NF-κB蛋白和基因表达升高(P<0.05)。与模型组比较,中药组、西药组病理积分和外周血中LPS含量降低(P<0.05),食管组织中TLR4、NF-κB蛋白和基因表达亦明显降低(P<0.05)。结论旋覆代赭汤能够减轻RE模型大鼠食管黏膜的损伤,抑制TLR4、NF-κB的表达,促进食管黏膜损伤的恢复。     

基于TGF-β1/p38MAPK/FN信号通路的放射性食管炎发病机制的研究

Objective To investigate the pathogenesis mechanism of radiation esophagitis from the perspective of mucosal regeneration and to determine whether it is associated with TGF-β1/p38MAPKs/FN signaling pathway. Methods The pathological analysis of esophageal specimens was performed by HE staining method. The expression of FN and TGF-β1 genes were observed by real time-PCR method, and the expression of tissue proteins TGF-β1, p38 and FN were detected by Western blot. Results The weights, food intakes and water intakes at the first week after the occurrence of radiation esophagitis were significantly decreased (P<0.05) and recovered at the fourth week. The esophageal mucosa was destructed at the first and second weeks, and the regeneration occurred in the fourth weeks; TGF-β1 and p38MAPK protein expression increased first and then decreased, while FN protein expression decreased first and then increased. Conclusion The TGF-β1/p38MAPK/FN signaling pathway may be involved in the process of mucosal repair. © 2020, CHINA RESEARCH ON PREVENTION AND TREATMENT. All rights reserved.     

朱生樑辨治难治性胃食管反流病经验撷英

介绍朱生樑教授辨治难治性胃食管反流病的经验。认为难治性胃食管反流病的辨证难点在于涉及多个脏腑,病程中又易形成内生之邪,相似证候、性质不同的病机常复合存在。提出立足主要矛盾、明辨脏腑自身及相似脏腑病机变化的特点、厘清虚实权重的辨证思路,在脏腑辨证结合气血津液辨证的基础上立法处方。并附验案2则。     

Gastro-oesophageal reflux in children: surgical management

Gastro-oesophageal reflux disease (GORD) is symptomatic reflux of gastric contents into the oesophagus. Factors predisposing to GORD are loss of the physiological antireflux barrier and anatomic abnormalities of the oesophagus or diaphragm. Conservative measures and medical management results in resolution of symptoms in a majority of children. Surgery is indicated in the event of failure of medical management or severe complications. Surgical procedures include open or laparoscopic fundoplication in children with normal neurology; fundoplication with or without vagotomy and pyloroplasty; surgical feeding jejunostomy and oesophago-gastric dissociation in the severely neurologically impaired children.     

Endovascular management of multiple intracranial dural arteriovenous fistulas

Background and purposeMultiply occurring intracranial dural arteriovenous fistulas (dAVFs) have been documented but rarely occur, and neither pathogenesis nor prognosis is clearly understood. This study was conducted to analyze angiographic characteristics of multiple dAVFs and to chronicle our treatment experience.MethodsBetween April, 2002 and January, 2018, data prospectively collected from 310 patients with intracranial dAVFs were systematically reviewed, assessing clinical and anatomic outcomes of endovascular treatment in 32 patients with multiple dAVFs (≥ 2 fistulas each). Lesions were categorized as multifocal or diffuse type, depending on presentation, and further characterized as progressive or non-progressive disease.ResultsOverall, 18 patients (56.3%) experienced aggressive presentations, including intracerebral hemorrhage or venous infarction. Cortical venous reflux (CVR) was observed in 26 patients (81.3%), and sinus thrombosis or occlusion was seen in 24 (75.0%). Clinical outcomes in patients with multifocal fistulas (n = 11) were excellent (100%), marked by a moderately high rate of complete occlusion (54.5%). Those with progressive disease (n = 10) regularly displayed certain angiographic findings, namely diffuse configuration (100%), sinus thrombosis (100%), and CVR (100%). Complete anatomic obliteration was achieved in 12 patients (37.5%), and in 26 patients (81.3%), clinical outcomes were favorable.ConclusionMultiple dAVFs are typically aggressive at presentation, given strong associations with CVR and sinus thrombosis. In diffuse-type fistulas, the potential to recur or progress is high. Although definitive treatment poses a challenge, outcomes of endovascular therapeutics may be still optimized in this setting through strategic procedural modifications and careful follow-up monitoring.     

Duodenogastric biliary reflux assessed by scintigraphic scan in patients with reflux symptoms after sleeve gastrectomy: preliminary results

BackgroundBile reflux is a factor in the appearance of severe esophagitis and Barrett’s esophagus, which have been reported after sleeve gastrectomy (SG). Incompetent lower esophageal sphincter and increased gastroesophageal acid reflux have been demonstrated after this operation. Some reports have shown bile content in the antrum during endoscopic control, but no investigations objectively confirm the presence of duodenogastric bile reflux in these patients.ObjectivesTo evaluate the presence of duodenogastric bile reflux (DGR) after SG in patients presenting reflux symptoms.SettingUniversity hospital.MethodsProspective study of 22 patients presenting reflux symptoms who underwent SG for morbid obesity and who received endoscopic evaluation and scintigraphic study to confirm esophagitis and duodenogastric bile reflux.ResultsErosive esophagitis was observed in 11 patients and Barrett’s esophagus in 2 patients. Seven patients (31.8%) presented positive DGR. Among them, 3 had type B and C esophagitis. The other 4 patients did not present esophagitis in spite of reflux symptoms.ConclusionDGR may be present in patients with gastroesophageal reflux after SG. This line of investigation requires further studies to confirm this hypothesis.
