腐蚀剂所致食管狭窄患者胆囊排空的改变

世界核心医学期刊文摘（胃肠病学分册） 2005年第8期1卷 10-11页

Ingestion of corrosive substances can lead to strictures of the esophagus and stomach. Cicatrization of the lower part of the esophagus can entrap vagal fibers in the process of fibrosis. The aim o f the present studywas to evaluate gallbladder dysfunction as a sequel to vagal damage in patients with corrosive-induced esophageal strictures. The cepha- lic phase of gallbladder emptying was stimulated by modified sham feeding acco rding to the chew-and-spit meth- od. gallbladder volume was measured by ultrasonography using the ellipsoid met hod after an overnight fast and every 15 min for a period of 90min after sham fe eding in 22 patients and 10 controls. Mean fasting gallbladder volume was signif icantly greater in patients than in controls (22.09±9.78 vs. 14.61±4.42 ml; P = 0.025). After sham feeding the gallbladder ejection fraction was significantly lower in patients than in controls(32.86±17.21 vs. 49.40±7.86%; P = 0.007).P atients with cicatrization in the distal one-third of the esophagus had a great er basal gallbladder volume (24.57±9.2 ml) and significantly lower ejection fra ction (20.47±8.9%) than patients with strictures at other sites (gallbladder v olume, 18.50±10.69 ml; ejection fraction, 47.48±13.3%; P=0.001). In conclusio n,patients with corrosive-in d- uced esophageal strictures,especially those in the distal one-third, had an i ncreased fasting gallbladder volume and decreased cephalic phase of gallbladder emptying, pointing to impaired vagal cholinergic transmission,possi- bly due to vagal entrapment in the cicatrization process.

Background: Fabella is a natural occurring sesamoid bone, cartilage or a mixture of both that is usually located at the posterolateral corner (PLC) of the knee [1]. Recently the PLC of the knee has been extensively investigated because it is a common site of injuries and diseases [2] [3]. The complexity of PLC anatomy needs to be fully understood because the fabella could be missed diagnosis as an osteochondral defect, osteochondritis dissecans (OCD), calcific tendinitis, or foreign body. We present a case report of fabella syndrome triggered by trauma and also performed a review of literature for the various diagnoses that might be confused with fabella syndrome. Case presentation: A 29-year-old, Sudanese male presented to the trauma center in King Khalid Hospital in KSA, complaining of pain and partial swelling in his left knee joint due to trauma. Fabella was detected in the posterior lateral corner (PLC) of the knee joint embedded in the lateral head of the gastrocnemius muscle. All other pathological conditions were excluded. Conclusion: Fabella is sesamoid bone with variable size, found in the PLC. Commonly if present it causes periodic pain especially in the fully extended knee or it remains asymptomatic. Trauma, surgery, sports or heavy extreme activities may trigger the pain of asymptomatic fabella. Clinicians should consider that pain in the PLC of the knee can result from the presence of the fabella in a condition called fabella syndrome.

数学信念就是人们对数学的看法，表现在对数学学科的看法、对数学教学的看法、对数学学习的看法．国内学者在数学信念方面的研究涉及的领域既有综合叙述型，又有比较研究型；既有针对大中小学生的研究，又有针对教师与数学家的调查．内地数学信念研究中，较多的是倾向于宏观论述，提出的大多是各自的想法和见解，实证研究方面及彼此观念间的融合有待加强；较多一块一块地进行，对于块与块之间联系的研究有待加强：在探讨不同的板块的关联时应给出启示．

采用基于PCR扩增的变性梯度凝胶电泳(PCR-DggE)技术,研究8种不同地理来源野生冬夏草中伴生细菌的群落结构,通过优势条带切胶测序分析,确定了不同来源冬虫夏草伴生优势细菌的种属信息,分析结果表明冬虫夏草中细菌群落多样性丰富,不同来源冬虫夏草的细菌多样性指数(H’)、丰度(D)和均匀度(J)均有所不同,且伴生细菌群落相似性与样品产地间的距离远近呈一定的正相关。本研究还发现了冬虫夏草样品中的4种共有细菌Flavihumibacter petaseus、Sphingomonas aestuarii、geobacillus pallidus和Methylovirgula ligni,为进一步研究伴生细菌在冬虫夏草生长发育中所起的作用奠定了基础。
