ObjectiveTo summarize the recent research progress on pathogenesis of human arrest defective 1(ARD1) protein in colorectal cancer and treatment process. MethodsSearched the related literatures from the databases such as CNKI, PubMed and so on, the relevant ARD1 in the development, diagnosis and treatment of colorectal cancer were reviewed. ResultsARD1 has effect of anti colorectal cancer, it can inhibit the proliferation and promote apoptosis of colorectal cancer cells, and improve the sensitivity of colorectal cancer cells to anticancer drugs at the cellular level. The treatment is mainly through the induction of cancer cell apoptosis or (and) decreased the proliferation ability of cancer cells, thus delaying the disease process. However, it is still in the research stage of animal experiments, which can not be directly applied to clinical practice. Conciusions ARDl study on the mechanism of anti colorectal cancer cells has become the focus of research with animal research and promotion, and provide new therapy concepts and measures for diagnosis and treatment of colorectal cancer.
【Abstract】ObjectiveTo study the mechanism of spontaneous rupture of hepatocellular carcinoma (HCC). MethodsArticles have been reviewed to find out the theory of spontaneous rupture of HCC. ResultsResearchful results suggested that the injury of small arteries was usually followed in patients of spontaneous rupture of HCC. In this review, the immune complex, which composed of hepatitis B virus e antigen, complement C1q and immunoglobulins, was found deposited in the elastic membrane of arteries. Likely as a result of immune complex deposition, vascular injury occurs mainly in the small arteries where the deposition of immune complex was present. The small arteries in which immune complex deposited are readily injuried and cause hemorrhage and rupture of HCC during vascular load increase. ConclusionWe would conclude that immune complex deposition in vessel wall led to the small arteries injury may be the factor involved in the pathogenesis of spontaneous ruptured HCC.
目的 探讨聚腺苷二磷酸核糖聚合酶-1（poly ADPribose polymerase-1,PARP-1） mRNA在重症急性胰腺炎(severe acute pancreatitis，SAP)大鼠肾脏中的表达及意义。方法 48只Wistar大鼠按随机数字表法分为SAP组和假手术组(SO)组，分别于造模术后1、3、6及12 h测定血清肌酐，观察胰腺和肾脏组织病理变化，并以RT-PCR法检测PARP-1 mRNA在肾脏中的表达水平。结果 SAP组大鼠术后血清肌酐逐渐升高，于3、6及12 h明显高于SO组(Plt;0.05)。SAP组大鼠术后胰腺出现腺体破坏、腺泡坏死、出血、炎性细胞浸润等病理损害，且呈进行性加重； SO组各时相胰腺组织基本正常。SAP组大鼠术后出现肾小管上皮细胞变性、坏死、肾小球瘀血、缺血等改变，并随时间延长逐渐加重，其损伤程度在3、6及12 h明显较SO组严重(Plt;0.05)。SO组大鼠肾脏组织仅表达少量PARP-1 mRNA，而SAP组大鼠随病程延长肾脏组织中PARP-1 mRNA表达逐渐增加，自3 h时起明显高于SO组（Plt;0.01）。结论 在SAP发病过程中，PARP-1 mRNA的表达在肾脏组织中逐渐增加，PARP-1可能参与了SAP相关肾损伤过程。
Objective To investigate the protective effects and the mechanism of recombinant human growth hormone on the intestinal barrier function. Methods The literatures of recent years were reviewed and summarized． Results The recombinant human growth hormone not only prevent mucosal cells and immunological cells from apoptosis, but also antagonize the damage of NO, cytokines, as well as endotoxin on intestinal barrier. What’s more, it increases the intestinal uptake and utilization of glutamine. All of the above could maintain the integrity and functions of the intestinal barrier. Conclusion The recombinant human growth hormone protects the intestinal barrier function through different ways.
ObjectiveTo explore and hypothesize the potential mechanisms of cancer stem cell(CSC) in peritoneal metastasis of gastric cancer. MethodsThe databases of PubMed and CNKI were searched, and relevant literatures were reviewed to draw out systematic hypotheses. ResultsMetastatic cancer stem cell(MCSC) was the subpopulation of CSC with the capacity of metastasis, had still not been well investigated. MCSC transfer was the tendency of migration and planting to specific target tissue by multi-steps of "homing" process. Peritoneal metastasis of gastric cancer was a simplified "homing" process, and we thinked that the key steps were adhesion, migration, and niche establishment of MCSC in peritoneum. That capturing human MCSC of peritoneal metastases in gastric cancer and identifying its stemness feature to determine high tumorigenicity and high invasive ability of it were the important research fields. ConclusionMCSC might play certain role in multiple processes in peritoneal metastasis of gastric cancer, but currently it's lack of relevant researches.
The study of relation between hepatogenic peptic ulcer and portal hypertension,transmitter metabolic disturbance,hepatic insufficiency and infection;and the therapeutic principles of complications of peptic ulcer are described.Twenty four of 58 patients with hepatogenic peptic ulcer were examined by color Doppler ultrasound.Portal venous flow volume (24 cases) was 1060.9±96ml/min.Portal venous pressure(8 cases)was 3.77±2.51kPa tested during operation.Histamine concentration (8 cases) was 0.70±0.31μmol/L in peripheral blood.The gastrin contents of 9cases tested 3cm,5cm away from the ulcer were 2195.6±1043.89ng/L and 2140.3±978.5ng/L respectively. H pylori positive rate was 80% in 58 cases.The therapeutic results were satisfactory with no death.The results suggest that pathogenesis of hepatogenic peptic ulcer is closely related to these factors foresaid.The treatment is nonsurgical and massive hemorrhage or perforation once occurs,surgical treatment is necessary.
