Objective To study the effect of intestinal trefoil factor on nuclear factor-κB in neonatal rats intestinal tissues with necrotizing enterocolitis, and to discuss whether ITF had protective function in NEC, and its role in the mechanism of NEC.

目的 研究肠三叶因子对坏死性小肠结肠炎新生大鼠肠黏膜组织核因子－κB表达的影响，探讨ITF是否对NEC具有保护作用及其在NEC发病机制中的作用。

Objective To establish a prokaryotic expression system for expressing mouse enterokinase which could recognize and cut the sequence of4-Lys in order to provide a technique platform for application of recombinant enterokinase.

目的：制备能在原核表达系统中表达并特异性识别4-Lys序列的鼠源性肠激酶，为推广应用重组肠激酶提供技术平台。

Recombinant mouse enterokinase can be expressed in Ecoli in inclusion manner so that the prokaryotic expression system for recombinant enterokinase with native conformation needs to be optimized.

鼠源性肠激酶轻链在原核细胞中多以包涵体形式表达，天然构象重组肠激酶的获得还需对表达系统进行优化。

Small intestinal biopsies showed subepithelial collagen deposition with varying degrees of villous atrophy and varying numbers of intraepithelial lymphocytes. Four patients had previous biopsies showing enteropathic changes without collagen deposition. Seven cases were associated with collagenous colitis and 1 also had features of lymphocytic colitis. Three patients also had collagen deposition in gastric biopsies. One case was associated with lymphocytic gastritis. Celiac disease (CD, gluten-sensitive enteropathy) was documented in 4 patients. Five patients made a clinical improvement with combinations of a gluten-free diet and immunosuppressive therapy. Two patients died of complications of malnutrition and 1 of another illness. Clonal T-cell populations were identified in 5 of 6 cases tested. Four of these patients improved clinically after treatment but 1 has died. Collagenous sprue evolved on a background of CD in 4 cases. There was no history of CD in others and these cases may be the result of a biologic insult other than gluten sensitivity.

小肠活检表现为上皮下胶原沉积，绒毛萎缩程度不一，上皮内淋巴细胞浸润数量不等。4例患者以往曾做过活检，表现为其他肠病改变，并没有胶原沉积。7例患者合并胶原性结肠炎，且1例还有淋巴细胞性结肠炎的特征。3例患者胃活检也发现有胶原沉积。1例患者合并淋巴细胞性胃炎。4例患者有乳糜泻（CD，谷蛋白敏感性肠病）病史。5例患者经无麸质饮食和免疫抑制治疗后，临床症状有所改善。2例患者因营养不良合并另一种疾病而死亡。6例患者做了T细胞受体基因重排，其中5例发现有克隆性T细胞群，这5例中有4例治疗后临床症状加重，且1例死亡。4例患者在CD的基础上病发胶原性口炎性腹泻；其余患者无CD病史，他们的发病也许是生物源性损害，而非谷蛋白敏感。

Result: 96 cases acute adhesive intestinal obstrnction patients recovered after conservative treatment. 4 cases that had peritonitis were treated with enterotomy.

结果：112例保守治疗后96例痊愈出院，其中16例2月后再次发作。9例有腹膜炎体征入院后行急诊手术治疗，术中出现有肠坏死作肠切除者4例。

These two traditional Chinese medicine has a strong antibacterial activity and, more importantly, they have an advantage that lower toxicity than traditional disinfectant drug - Formocresol, CP. In order to help in the developmentof new strategies to prevent or eliminate the infection byE. faecalis, thereby improving treatment results in endodontics and give a reference to clinical application, In this research , using traditional Drug formocresol and the current most respected calcium hydroxide ( calcium hydroxide mixed with propylene glycol ) as the conventional control, we investigated the antimicrobial activity of Chinese herbs cinnamic aldehgd and Chinese gallnut against E. faecalis in root canals in vitro.

上述两种中药都具有很强的抗菌作用，更重要的是它们作为中药具有较传统消毒药物—甲醛甲酚、樟脑酚毒副作用小的优点，本研究通过离体牙根管消毒实验，并用传统消毒药物甲醛甲酚及当前最受推崇的氢氧化钙制剂做为常规对照，对两种中药的抗粪肠球菌性能进行评价，以期探讨更有效且安全的抑制或杀灭粪肠球菌的方法，提高根管治疗的成功率，为临床应用提供一定参考。
