AIM: To compare expression of Ca2+-regulating proteins in upper gastrointestinal (GI) tract of achalasia patients and healthy volunteers and to elucidate their role in achalasia. METHODS: Sarcoplasmic reticulum Ca2+ ATPase (SERCA) isoforms 2a and 2b, phospholamban (PLB), calsequestrin (CSQ), and calreticulin (CRT) were assessed by quantitative Western blotting in esophagus and heart of rats, rabbits, and humans. Furthermore, expression profi les of these proteins in biopsies of lower esophageal sphincter and esophagus from patients with achalasia and healthy volunteers were analyzed. RESULTS: SERCA 2a protein expression was much higher in human heart (cardiac ventricle) compared to esophagus. However, SERCA 2b was expressed predominantly in the esophagus. The highest CRT expression was noted in the human esophagus, while PLB, although highly expressed in the heart, was below our detection limit in upper GI tissue. Compared to healthy controls, CSQ and CRT expression in lower esophageal sphincter and distal esophageal body were signif icantly reduced in patients with achalasia (P < 0.05). CONCLUSION: PLB in the human esophagus mightbe of lesser importance for regulation of SERCA than in heart. Lower expression of Ca2+ storage proteins (CSQ and CRT) might contribute to increased lower esophageal sphincter pressure in achalasia, possibly by increasing free intracellular Ca2+.

Xanthogranulomatous cholecystitis （XGC） is a destructive inflammatory disease of the gallbladder, rarely involving adjacent organs and mimicking an advanced gallbladder carcinoma. The diagnosis is usually possible only after pathological examination. A 46 year-old woman was referred to our center for suspected gallbladder cancer involving the liver hilum, right liver lobe, right colonic flexure, and duodenum. Brushing cytology obtained by endoscopic retrograde cholangiography （ERC） showed high-grade dysplasia. The patient underwent an en-bloc resection of the mass, consisting of right Iobectomy, right hemicolectomy, and a partial duodenal resection. Pathological examination unexpectedly revealed an XGC. Only six cases of extended surgical resections for XGC with direct involvement of adjacent organs have been reported so far. In these cases, given the possible coexistence of XGC with carcinoma, malignancy cannot be excluded, even after cytology and intraoperative frozen section investigation. In conclusion, due to the poor prognosis of gallbladder carcinoma on one side and possible complications deriving from highly aggressive inflammatory invasion of surrounding organs on the other side, it seems these cases should be treated as malignant tumors until proven otherwise. Clinicians should include XGC among the possible differential diagnoses of masses in liver hilum.

背景虽然当前已有一些评估卫生保健指南可靠性的工具,但仍缺乏针对制定指南实际步骤的指导。针对指南制定者们所需考虑的相关资源和工具,我们系统研发了一份全面的条目清单,但这并不意味着每篇指南都需遵守该清单的所有条目。方法我们检索了国际指南制定机构的指南制定手册、指南的指南(主要是来自国际和国家机构以及专业学会的方法学报告),以及提供系统指导的最新文章。经过反复评价这些资料,尽可能全面地罗列和提取条目,并制定与指南有关的重要主题。通过反复讨论,我们对条目进行评价以去重和补漏,同时邀请指南制定专家对所增加的条目进行修改并提出建议。结果我们制定了一份包含18个主题、146个条目的清单,并建立了帮助指南制定者应用这些条目的网站。这些主题和条目涵盖了指南从规划、完成、实施和评估的全过程。最终的清单版本也包括了培训所需的资料以及应用这些条目时用到的方法学参考文献的链接。解释本清单将提供给指南制定者用作参考。仔细考虑清单中的条目将有助于指南的制定、实施和评估,我们也将会通过大众反馈来修订并持续更新清单。
