目的:观察人慢性萎缩性胃窦炎( Chronic atrophic antral gastritis ,CAAG)与生长抑素( so-matostatin,SST)水平降低、胃黏膜适应性保护的关系。方法:临床纳入CAAG患者75例,对患者的胃黏膜进行活检,并对患者的外周血液进行采集。采用放射免疫法检测组织标本以及血样中的SST 水平。光镜、电镜下观察胃黏膜的组织以及超微结构的改变。另外,采用免疫组化法对SST在胃窦黏膜中的分布进行半定量检测。结果:CAAG患者胃窦D细胞的数量较正常人显著降低,黏液上皮细胞胞质内线粒体出现肿胀,线粒体嵴发生断裂,粗面内质网扩张,黏原颗粒数量降低,细胞内核膜消失,染色质聚集。 CAAG患者血液、上皮+隐窝部SST 水平分别为(10.51±7.60)pg/100μL、(1.29±1.58)pg/μL蛋白,正常人分别为(21.17±12.81)pg/100μL、(4.78±9.53)pg/μL蛋白,差异有显著性(P<0.05);CAAG患者隐窝SST水平为(6.79±3.15)×103,正常人隐窝SST水平为(36.5±15.24)×103,差异有显著性( P<0.05)。结论:在无全身炎性反应的情况下,机体幽门腺D细胞生成SST的能力降低,与CAAG及胃黏膜适应性保护削弱有关。
目的:觀察人慢性萎縮性胃竇炎( Chronic atrophic antral gastritis ,CAAG)與生長抑素( so-matostatin,SST)水平降低、胃黏膜適應性保護的關繫。方法:臨床納入CAAG患者75例,對患者的胃黏膜進行活檢,併對患者的外週血液進行採集。採用放射免疫法檢測組織標本以及血樣中的SST 水平。光鏡、電鏡下觀察胃黏膜的組織以及超微結構的改變。另外,採用免疫組化法對SST在胃竇黏膜中的分佈進行半定量檢測。結果:CAAG患者胃竇D細胞的數量較正常人顯著降低,黏液上皮細胞胞質內線粒體齣現腫脹,線粒體嵴髮生斷裂,粗麵內質網擴張,黏原顆粒數量降低,細胞內覈膜消失,染色質聚集。 CAAG患者血液、上皮+隱窩部SST 水平分彆為(10.51±7.60)pg/100μL、(1.29±1.58)pg/μL蛋白,正常人分彆為(21.17±12.81)pg/100μL、(4.78±9.53)pg/μL蛋白,差異有顯著性(P<0.05);CAAG患者隱窩SST水平為(6.79±3.15)×103,正常人隱窩SST水平為(36.5±15.24)×103,差異有顯著性( P<0.05)。結論:在無全身炎性反應的情況下,機體幽門腺D細胞生成SST的能力降低,與CAAG及胃黏膜適應性保護削弱有關。

Objective: To observe the chronic atrophic antral gastritis ( CAAG ) and somatostatin ( SST ) , the relationship between reduced levels of gastric mucosal adaptive protection .Method: Clinical CAAG patients included 75 cases , biopsy of gastric mucosa , and collected the patient's peripheral blood .Ra-dioimmunoassay was applied to detect the level of SST in blood and tissue specimens .Light microscope , elec-tron microscope observation of gastric mucosa and the ultrastructure changes .In addition, immunohistochem-istry method was used for semi quantitative detection on the distribution of SST in the gastric antrum mucosa in the.Result: The number of CAAG patients with gastric antral D cells decreased obviously than that in controls group , mucinous epithelial cell mitochondria swelling , mitochondrial crista rupture , dilation of rough endoplasmic reticulum , mucous granules in the cell number decreased , the nuclear membrane disappeared , chromatin aggregation.CAAG patients with blood, crypt epithelial +SST levels were (10.51±7.60) pg/100μL, (1.29±1.58) pg/μL protein, normal people were (21.17±12.81) pg/100μL, (4.78±9.53) pg/μL protein, the difference was significant (P <0.05);CAAG SST level for patients recess (6.79±3.15) × 103, SST level in normal people recess is (36.5±15.24)×103, the difference was significant (P <0.05). Conclusion:In the absence of systemic inflammatory reaction conditions , reduce the ability of the body py-loric gland D cell generation SST , associated with CAAG and gastric mucosal adaptive protection weakened .
