    • 缺血預處理對脊髓缺血損傷細胞內Ca2+變化的影響

      目的 觀察缺血預處理對脊髓缺血損傷細胞內Ca2+變化的影響. 方法 將44只健康新西蘭大白兔隨機分為三組:缺血組20只,缺血預處理組20只,假手術組4只.缺血組于左腎動脈下夾閉腹主動脈40分鐘后開放灌注;缺血預處理組夾閉腹主動脈5分鐘,開放15分鐘,再次夾閉40分鐘后開放再灌注;假手術組動物手術操作同缺血組,但不夾閉腹主動脈.分別于夾閉40分鐘后即刻、開放再灌注2小時、8小時、24小時和72小時各時相點測定脊髓組織Ca2+含量,并評定、記錄動物后肢神經功能. 結果 缺血預處理組脊髓組織Ca2+顯著低于缺血組各時相值;再灌注8小時后神經功能評分缺血預處理組明顯高于缺血組(P<0.01). 結論 缺血預處理具有降低神經元胞漿游離Ca2+濃度,防止Ca2+超載,穩定細胞內環境的能力,對主動脈阻斷所致的脊髓缺血損傷有良好的保護作用.其表現為明顯降低癱瘓發生率,增加術后神經評分.

    • Clinical Significance and Expression of T Helper Cell Secretory Cytokines in Esophageal Squamous Cell Carcinoma Tissues

      Objective To investigate the clinical significance and expression of T helper cell secretory cytokines in esophageal squamous cell carcinoma tissues, which provide theoretical basis of reasonable and effective therapy for patients with esophageal carcinoma. Methods Fifty-six specimens of patients who underwent esophageal carcinoma resection were divided into two groups. Group A (n=28) included grade Ⅰand Ⅱ specimens of esophageal squamous cell carcinoma, group B (n=28) included grade Ⅲ and Ⅳ specimens of esophageal squamous cell carcinoma. Control group included 6 specimens of esophagitis. The expression of tumor necrosis factor alpha (TNF-α), interleukin 10 (IL-10) and transforming growth factor beta (TGF-β) in all specimens were detected. Results The positive expression of TNF-α,TGF-β and IL-10 in group A and group B were significantly higher than those in control group(Plt;0.01); the positive expression of TNF-α in group A was higher than that in group B, while the positive expression of TGF-β and IL-10 were lower than those in group B (Plt; 0.01). There was negative correlation between the positive expression of TNF-α and IL-10, TGF-β(Plt;0.01), and positive correlation between TGF-β and IL-10 (Plt; 0.01). The positive expression of TNF-α in patients of survival period in 3 years was lower than that exceed 3 years(F=36.25 ,Plt;0.01),while the positive expression of IL-10 and TGF-β in the patients of survival period in 3 years were higher than those exceed 3 years(F=29.29,26.69;Plt;0.01). Conclusion By the way of changing the level of cytokines secretion from T helper cells, esophageal squamous cell carcinoma tissues destroyed the balanced condition of patient’s immune system, which made esophageal carcinoma tissues escape the attack from the patient’s immune system and promote the invasion into surrounding tissues.
