        • 甲亢合并巨幼紅細胞性貧血臨床研究(附2例報告)

          目的:探討甲狀腺機能亢進(甲亢)所致巨幼紅細胞性貧血(巨幼貧)原因及預防策略。方法:回顧性分析2例甲亢合并巨幼貧的臨床資料。結果:長期甲亢耗竭維生素B12,葉酸造成缺乏和胃腸蠕動增強及伴發病如胃炎等致吸收障礙,導致營養缺乏性巨幼貧。結論:甲亢需要營養物質較正常人多,預見性補充維生素B12,葉酸可防止巨幼貧發生或減輕其貧血程度。

        • 低鉀周期性麻痹發病機制的研究進展

          低鉀周期性麻痹(HypoPP)是一組以反復發作的骨骼肌弛緩性癱瘓伴低血鉀為特征的疾病,嚴重者可以引發呼吸肌麻痹,惡性心律失常甚至死亡。目前HypoPP的診斷以臨床診斷為主,對該病早期的篩查和診斷尤顯重要。研究表明原發性HypoPP與遺傳相關,已明確CACNA1S和SCN4A兩個相關基因,同樣,對甲亢性HypoPP研究認為,它是由遺傳易感性、甲狀腺毒癥和環境因素三者共同作用引起的內分泌性通道疾病。對HypoPP的基因研究不僅豐富該病的基因庫,還能早期對可疑基因進行重點篩查,早期識別易感人群,積極避免疾病嚴重后果發生。現對HypoPP發病機制進行綜述,以期為臨床工作中對HypoPP的早期篩查和診斷提供參考依據。

        • 甲狀腺癌分子生物學研究進展

          甲狀腺癌是內分泌系統最常見的腫瘤,且各國甲狀腺癌發病率不斷上升。依據不同的組織學和臨床特征,濾泡細胞來源的甲狀腺癌分為高分化癌(包括乳頭狀癌、濾泡狀癌)和未分化癌。另有起源于濾泡旁降鈣素分泌細胞的甲狀腺髓樣癌。隨著分子生物學的發展,與甲狀腺癌有關的基因突變不斷被人們所認識。近年來,分子靶向治療成為研究熱點,多種治療甲狀腺癌的分子靶向藥物進入臨床試驗階段,為甲狀腺癌尤其是難治性甲狀腺癌的治療帶來希望。現就甲狀腺癌的分子生物學研究進展作一綜述。

        • 蠟狀芽孢桿菌分泌的致吐毒素對胰島β細胞毒性作用研究進展

          糖尿病是一種常見病、多發病,其患病率呈上升趨勢,且認為這種上升趨勢與環境因素有關,但具體的影響因素目前尚不明確。特定蠟狀芽孢桿菌株分泌的致吐毒素主要存在于淀粉類食物中,由于其耐熱、耐酸及不易被蛋白水解酶破壞的特性,使其很難從食物及消化道清除。致吐毒素具有鉀離子載體的特性,通過破壞胰島β細胞線粒體跨膜電位導致胰島素分泌減少以及細胞凋亡。體外研究顯示,極低劑量的致吐毒素也具有毒性作用,而胰島β細胞對其尤為敏感。然而目前尚缺乏相關的體內研究,未來亟需進行相關體內研究,以進一步闡明致吐毒素與糖尿病發生的相關性。

        • Preliminary Study on the Relationship between Growth Hormone Releasing Hormone Receptor and Adrenal Tumors

          目的 初步探討生長激素釋放激素受體(GHRHR)在腎上腺腫瘤組織中的表達及其在臨床中的實際應用價值。 方法 應用免疫組織化學方法檢測2001年1月-2009年10月間187例腎上腺腫瘤和20例正常腎上腺組織標本中GHRHR的表達。 結果 腎上腺皮質腫瘤與腎上腺髓質腫瘤、正常腎上腺組織比較,GHRHR表達明顯增高(陽性率分別為99%、45%、55%),GHRHR在腎上腺皮質醇瘤和醛固酮瘤中表達的差異有統計學意義,在腎上腺皮質腺瘤、皮質腺癌、皮質增生中表達的差異有統計學意義。 結論 GHRHR在人正常腎上腺及腎上腺腫瘤組織中的表達,為在垂體外組織及人類腫瘤組織存在GHRHR的表達提供了直接證據;GHRHR可能會用于腎上腺皮質腫瘤和髓質腫瘤的鑒別診斷,但GHRHR尚不能用于良性和惡性腎上腺皮質腫瘤的鑒別診斷。GHRHR在腎上腺皮質相關腫瘤的高表達,可能與腎上腺皮質腫瘤的發病機制有關。

        • Comparison between Assay of Immunoblotting Test, ELISA and RIA in Detection for Islet Autoantibodies

          目的:評價免疫印跡法檢測胰島自身抗體(GAD-A、ICA、IAA)與酶聯免疫法測ICA、GAD-A放射免疫法測IAA結果的一致性。方法:采用免疫印跡法測定81例糖尿病患者胰島自身抗體,將結果與酶聯免疫法測定的GAD-A、ICA,放射免疫法測定IAA結果進行比較。結果:免疫印跡法陽性檢出率為:GAD-A 51.8%,ICA 18.5%,IAA 27.1%;酶聯免疫法(GAD-A、ICA)、放射免疫法(IAA)陽性檢出率:GAD-A 32.1%,ICA 34.5%,IAA 30.8%;上述兩組結果進行比較,兩組相比ICA和GAD-A有統計學差異(Plt;0.05),IAA無統計學差異。兩組結果一致率比較:GAD-A 50.6%,ICA 64.2%,IAA 69.1%。結論:與臨床常用酶聯免疫法檢測GAD-A、ICA,放射免疫法檢測IAA比較,免疫印跡法和酶聯免疫法在ICA及GAD-A陽性檢出率上的差異有顯著性,和放射免疫法在IAA陽性檢出率上差異無顯著性。

        • Influence of Hydrochloric Acid to the Measurement of Free Cortisol in 24-hour Urine

          目的 研究尿標本中防腐劑鹽酸對24 h尿游離皮質醇測定的影響。 方法 收集2008年7月-2009年1月正常人、庫欣病患者及其他疾病患者的24 h尿液,混勻后,一部分濃鹽酸防腐,一部分未加鹽酸直接保存。電化學發光免疫分析法同步檢測尿游離皮質醇濃度。 結果 經配對 t 檢驗加濃鹽酸后的24 h尿游離皮質醇測值均高于未加酸者,比較有統計學意義(Plt;0.05)。加鹽酸和未加鹽酸所測尿游離皮質醇二者之間具有較好的相關性,相關系數 r =0.97,P lt;0.05。 結論 濃鹽酸防腐的標本24 h尿游離皮質醇測值較未加酸保存的標本高。因此,為了得到相對準確的值,更好地反映腎上腺實際分泌情況,測定24 h尿游離皮質醇的標本不應使用鹽酸防腐。

        • Effects of Venlafaxine and Carbamazepine for Painful Peripheral Diabetic Neuropathy: A Randomized, Double-blind and Double-dummy, Controlled Multi-center Trial

          Objective To evaluate the safety and efficacy of venlafaxine and carbamazepine on painful peripheral diabetic neuropathy. Methods This was a randomized, parallel-group, double-blind, double-dummy clinical trial. 132 patients a venlafaxine group (n=66) and a carbamazepine group (n=66) with painful peripheral diabetic neuropathy were recruited from 3 clinical centers. The venlafaxine group took venlafaxine 25 mg plus one dummy carbamazepine tablet twice a day and the carbamazepine group took carbamazepine 0.1 g plus one dummy venlafaxine tablet twice a day both for 2 weeks. The primary efficacy measurement consisted of a numeric pain intensity scale and the secondary measurement assessed quality of life. Results One hundred and nineteen patients completed the trial. Venlafaxine was superior to carbamazepine in improving mean pain intensity scores at 5,7,10 and 14 days by per-protocol analysis (P=0.02, P=0.03, P=0.003 and P=0.001 respectively). The effects of venlafaxine on the improvement in the total quality of life scores were better than those of carbamazepine at 10 and 14 days (P=0.02 and P=0.01 respectively). Sleep interference and mood were improved by both venlafaxine and carbamazepine, but the efficacy of venlafaxine was superior to that of carbamazepine. The common adverse events of venlafaxine included mild gastrointestinal discomfort, dizziness and somnolence. The frequency of adverse events in the venlafaxine group was about 43.9% (4 patients withdrew because of adverse events) and in the carbamazepine group about 25.76% (2 patients withdrew because of adverse events) (P =0.06). Conclusions Venlafaxine and carbamazepine are effective in the treatment of painful diabetic neuropathy, venlafaxine is superior to carbamazepine in improving pain and quality of life. Both drugs may be safe and well tolerated.
