        • Effects of Improved Gastric Lavage for Patients of Acute Poisoning

          目的 探討改良洗胃法在急性中毒患者洗胃中的應用效果。 方法 將2010年1月-2012年2月收治的口服藥物中毒需采用電動洗胃機洗胃的患者分為觀察組和對照組,觀察組采用改良洗胃法,對照組采用傳統的洗胃方法,比較兩組患者洗胃總時間、洗胃總液量、一次性插管成功率、堵管發生率及并發癥發生率。 結果 觀察組患者洗胃總時間低于對照組[(28.60 ± 6.32)、(34.51 ± 5.37)min],洗胃總液量低于對照組[(10 856 ± 3 818)、(17 962 ± 3 855)mL],差異有統計學意義(P<0.001);一次性插管成功率高于對照組(93.02% 、67.44%),差異有統計學意義(P=0.03);堵管發生率為低于對照組(4.88%、27.91%),差異有統計學意義(P=0.03);并發癥發生率低于對照組(2.33%、37.21%),差異有統計學意義(P<0.001)。 結論 改良洗胃法可減少洗胃總時間及洗胃液總量,提高一次性插管的成功率,同時可降低堵管及并發癥的發生率。

        • 小卡子在防止重癥患者胃內容物外溢中的應用及效果

          目的 總結和驗證小卡子在防止危重患者腸內營養液及管喂藥物后2 h內發生外溢的方法及效果。 方法 2011年5月-8月將ICU收治的80例需管喂的危重患者,隨機分為兩組,對照組采用傳統的胃管末端蓋子封閉胃管,試驗組采取胃管遠端加設小卡子夾閉胃管封閉法,比較兩種方法在預防胃內容物外溢中的作用及效果。 結果 試驗組患者無1例發生胃內容物外溢,兩組比較差異有統計學意義(P<0.05)。小卡子夾閉胃管可有效防止胃內藥物或營養物質丟失。 結論 在胃管遠端使用小卡子夾閉胃管的方法能有效降低胃內容物外溢發生率。

        • CLINICAL FEATURES AND THE CAUSES OF MISDIAGNOSIS OF GASTRIC EOSINOPHILIC GRANULOMA (A REPORT OF 14 CASES)

          目的 探討胃嗜酸性肉芽腫的診斷、誤診原因和治療方法。方法 對14例胃嗜酸性肉芽腫的臨床資料進行回顧性分析。結果 全部病例均有上腹疼痛和返酸史; 伴潰瘍形成11例,穿孔4例,上消化道出血3例; 術前行胃鏡檢查2例,X線鋇餐透視檢查6例,無1例獲確診; 其余病例亦全部誤診為胃潰瘍或癌腫。結論 胃鏡多部位取材,特別是在潰瘍與周邊粘膜移行處,采取挖掘式取材,能減少誤診率; 胃大部切除術是主要的治療方法。

        • APPLICATION OF THE THREE PTERGOID FORCEPS ON RECONSTRUCTION OF GASTROENTERIC DUCT (A REPORT OF 40 CASES)

          目的 推薦在胃底賁門癌和直腸上段癌切除的病例,如果無條件使用胃腸吻合器,在胃腸道重建吻合時應用三翼鉗。方法 我科自1990年7月至1998年11月在胃底賁門癌和直腸上段癌切除術中,應用三翼鉗進行胃腸道重建吻合共40例。其中全胃切除12例,近側胃切除7例,直腸上段及部分乙狀結腸切除21例。重建術式有: 食管空腸Roux-Y吻合5例,食管空腸袢式吻合2例,食管十二指腸吻合3例,橫結腸間置代胃2例,食管胃吻合7例,乙狀結腸、直腸盆內吻合21例。結果 全部手術除1例術后死于呼吸衰竭外均恢復順利出院,無1例發生吻合口瘺。術后病理證實僅1例遠側直腸端可見癌細胞浸潤,其它均證實兩斷端已切干凈。隨訪半年內發生吻合口狹窄4例。結論 對胃底賁門癌或直腸上段癌切除的病例應用三翼鉗技術有如下優點: ①食管或直腸切除長度符合腫瘤切除標準; ②吻合時兩端對合整齊,且無張力; ③吻合端不出血,視野清晰; ④吻合操作時從容穩定; ⑤全層吻合確實,可靠; ⑥結腸吻合時可避免糞便污染。

        • Expressions and Significances of HIF-1α and BAK in Gastric Cancer

          目的 探討HIF-1α和BAK蛋白在胃癌中的表達情況,以及二者在胃癌中的相互關系及作用。方法 應用免疫組化SABC染色法檢測80例胃癌組織和20例正常胃組織中的HIF-1α和BAK蛋白的表達情況。結果 胃癌中HIF-lα和BAK蛋白的表達陽性率分別為56.3%(45/80)和67.5%(54/80),而在胃正常組織中分別為5.0%(1/20)和20.0%(4/20),二者在胃癌中的表達顯著高于胃正常組織,其差異有統計學意義(P<0.05)。HIF-1α蛋白表達與胃癌組織的浸潤范圍、分化程度及淋巴結轉移有關(P<0.05),與臨床分期、年齡及性別無關(P>0.05);BAK蛋白表達與胃癌浸潤及分化程度相關(P<0.05),與淋巴結轉移、臨床分期、年齡及性別無關(P>0.05)。胃癌組織中HIF-1α與BAK蛋白的陽性表達之間呈正相關(列聯系數r=0.056,P<0.05)。結論 HIF-1α與BAK蛋白在胃癌的臨床分期及浸潤轉移中存在關系,這對于研究胃癌的發生和發展,以及對于探索以二者為靶點的抗腫瘤治療有重要意義。

        • Efficacy of Cinobufacin for Stomach Cancer: A Systematic Review

          目的 系統評價華蟾素治療胃癌的療效。 方法 計算機檢索Cochrane (2011年第3期),PubMed (1966年1月-2011年9月),EMBASE(1974年1月-2011年9月),中國生物醫學數據庫(CBM,1978年1月-2011年9月),維普(1989年1月-2011年9月),中國期刊全文數據庫(1994年1月-2011年9月);手工檢索相關雜志。納入華蟾素治療胃癌的隨機對照試驗(RCT),對納入的RCT進行質量評價,并用RevMan 5.0軟件進行Meta分析。 結果 共納入9個RCT,Meta分析結果顯示:華蟾素聯合常規化學療法(化療)治療中晚期胃癌的有效率高于常規化療組,且差異有統計學意義[RR=1.23,95%CI(1.03,1.46),P=0.02],而1年生存率兩組比較差異無統計學意義[RR=1.28,95%CI(0.69,2.36),P=0.43]。 結論 常規化療加華蟾素治療胃癌的療效優于常規化療,但因為納入研究質量較低,尚需高質量、大樣本、長期的隨機對照試驗進一步驗證上述結論。

        • Study on Expression of Urokinase-Type Plasminogen Activator mRNA in Gastric Cancer

          Objective To investigate the expression of urokinase-type plasminogen activator (uPA) mRNA in gastric cancer tissues and cancer-adjacent tissues and the relationship between its expression and biologic behavior of tumor. Methods Fourty-eight cases with gastric cancer were detected for the expression of uPA mRNA by fluorogenic probe quantitative reverse transcription polymerase chain reaction (RTPCR). Results The positive expression rate of uPA mRNA was 83.3%, 25.0%, 93.8% and 62.5% in gastric cancer tissues,cancer-adjacent tissues, gastric cancer tissues with lymph node metastasis and with non-lymph node metastasis respectively. Expression of uPA mRNA was positively related with the invasion depth of gastric cancer. Conclusion Expression of uPA mRNA is significantly increased in gastric cancer and it can be used as an indicator to judge the metastasis and prognosis of tumor.

        • Effect of Preoperative Gastric Arterial Chemoembolization on Apoptosis of Lymph Node Metastasis of Gastric Cancer

          【Abstract】ObjectiveTo study the effect of preoperative gastric arterial chemoembolization on apoptosis of lymph node metastasis of gastric cancer. MethodsForty patients with gastric cancer and lymph node metastasis underwent curative resection, among which there were 20 patients who received the preoperative gastric arterial chemoembolization, and they constituted the treatment group. The rest of the patients were included in the control group. The expressions of p53, CD95 and bcl-2 were examined by immunohistochemistry and apoptosis in the lymph node metastasis was examined by in situ terminal transferasemediated dUTP nick end labeling (TUNEL). ResultsThe expression intensity of p53 and CD95 in lymph node metastasis of treatment group increased more significantly than that of control group, whereas the expression intensity of bcl-2 decreased in treatment group. There was a significantly positive correlation between the expressions of p53 and CD95 and the apoptosis.ConclusionPreoperative gastric arterial chemoembolization may affect the expressions of p53, CD95 and bcl-2 and may induce the apoptosis of lymph node metastasis. It may be helpful to improve the effect of curative resection of gastric cancer.
