Gastrointestinal bleeding is a severe,complicated and commonly seen disease in Department of Digestive Diseases,the frequent etiology is peptic ulcer,acute gastric mucosal lesion,esophageal gastric varices and digestive tract tumors. In recent years,clinicians gradually noticed a kind of disease characterized by acute,recrudescent and life-threatening bleeding,that is the non-variceal vascular originated gastrointestinal hemorrhage. The guidelines and scholars have not paid enough attention to this problem. However,non-variceal vascular originated gastrointestinal hemorrhage is not uncommon,and is difficult and tricky in its management for clinicians. Therefore,clinicians should pay sufficient attention to the characteristics and therapeutic principles of non-variceal vascular originated gastrointestinal hemorrhage.

P300/CBP is one of the most important high molecular weight protein histone acetyltransferase ( HAT) Although it is encoded by multiple different genes , P300/CBP is highly homologous , Because they have the similar amino acid sequence and functions ,and belong to the same class of proteins ,normolly they are all called P300/CBP.P300/CBP is involved in the activation of many kinds of transcription factors ,the protein itself alsohas acetyltransferase activity ,and is capable of acetylation of 4 core histones and transcription factor .More and more studies have confirmed the relationship of P 300/CBP variation withmultiple human diseases , including in-flammation,diabetes,heart disease and especially cancer .In tumor P300/CBP is associated with some pathways , and these pathways play a different roles in the tumor .Although P300/CBP is usually regarded as a tumor sup-pressor factor ,is plays different roles in different tumors ,This review mainly introduces the relationship of P 300/CBP with some solid tumor disease genes ,related transcription factors and their signaling pathways .

Radiotherapy is important in cancer treatment, but improving the therapeutic effect of irradiation and decreasing its toxicity to normal human tissues is still a global problem. Epidermal growth factor receptor (EGFR) is a member of ErbB family and is an important transmembrane receptor with signal-transduction tyrosine kinase activity. EGFR can direct cellular migration, adhesion, proliferation, differentiation, and apoptosis, and plays a fundamental role in the development and growth of many types of human tumor cells. A series of preclinical studies showed that EGFR inhibitors can enhance the antitumor activity of ionizing radiation. EGFR inhibi-tors regulate radio-sensitization through multiple mechanisms, including cell cycle alterations, DNA repair modulation, and anti-angio-genesis. Reasonable application of EGFR inhibitors will effectively increase the radio-therapeutic effect, extend the local control of tu-mor, and improve a patient's quality of life.

Of all types of intracranial hemorrhage (ICH) in the neonates, germinal matrix intraventricular hemorrhage(GM-IVH) in the premature infant is the most common type, mainly attributed to the existence of immature germinal matrix, lt's usually lack of visible and specific symptoms and signs in the nervous system, so its early and final diagnosis depends on the imaging examine. GM-IVH can cause periventricular hemorrhagic infarction, post-hemorrhagic hydrocephalus, periventricular leukomalacia and the associated cerebellar hemorrhagic injury, which are critical determinants of neonatal morbidity, mortality, and neurodevelopmental outcome in the survivors. The overall aim of this article is to review the current knowledge of the cause,mechanisms, imaging diagnosis, complication, management and outcome of GM-IVH in the preterm infant.

Many studies have demonstrated that blockade of angiogenesis by antiangiogenic drugs in di-fferent ways can control the growth of tumor.Antiangiogenic agents can target different sites:vascular growth pro-moting f_ators,endothelial cells,basement membrane degradation,epidermal growth factor receptor,ete.Antian-giogenic agents have promising prospect.

Method 118 patients with vocal cord polyp from November 2013 to August 2015 in our hospital were chose as research subjects, all patients were divided into observation group (n=54) and control group (n=64) accord﹣ing to different treatment. Control group: patients received conventional laryngoscope resection; observation group:patients received CO2 laser under suspension laryngoscope. Then compare the two group patients' voice indexes, a﹣cute phase proteins, rehabilitation and recovery speed after treatment. Results Observation group patients' F0, HNR values were higher than control group patients, PPQ, APQ, NNE values were lower than that in control group (P<0.05);early observation group patients' postoperative serum CRP, α1-AG, CER,β2-MG values were lower than con﹣trol group patients, ALB value was higher than control group patients (P< 0.05); observation group patients' cure rate was higher than control group patients, valid and invalid rates were lower than control group patients, the first sound time, sound full recovery time, discharge time were shorter than control group patients (P< 0.05). Conclusion Vocal cord polyp patients receive laser under suspension laryngoscope treatment, can effectively promote recovery rate, have advantages of minimally invasive and rapid recovery after surgery.

Objective To discuss the application of Chinese version of Stanford Acute Stress Reaction Questionnaire (SASRQ) in trau-matic fracture patients. Methods 96 patients with traumatic fracture in the Second Hospital of Tangshan City were recruited in the early stage. All the subjects were assessed with SASRQ in 2 weeks after trauma for the first time, and then they were assessed with SASRQ for the second time after an interval of 2 days. 496 patients with traumatic fracture completed SASRQ and Abbreviated Injury Scale-Injury Se-verity Score (AIS-ISS) assessment. Results The Cronbach's alpha was 0.930 in SASRQ, and were 0.729~0.812 in each dimension (P<0.01). Test-retest reliability at 2-day intervals was 0.980 (P<0.01). 133 cases (26.8%) were detected with acute stress disorder (ASD). According to a single entry≥3 as a positive screening, 31.7%suffered separation symptoms, 49.6%suffered re-experience traumatic symptoms, 39.5%suffered avoidance symptoms, 75.6%suffered symptoms of anxiety or increased awareness. The scores of SASRQ (t=37.807, P<0.05) and each dimension (t=36.503, 29.019, 31.111, 19.369, respectively, P<0.001) was significantly higher in the ASD positive group than in the neg-ative group. There was significantly difference in the score of SASRQ and each dimension in different age groups (F=112.319, 94.109, 95.099, 103.291, 61.497, respectively, P<0.001), the acute stress symptoms were lighter in the older group than in the other groups. There was significantly difference in the score of SASRQ and each dimension between men and women (t=7.707,-6.190,-8.944,-7.221,-9.949, respectively, P<0.001), the acute stress symptoms were lighter in men than women. There was sig-nificantly difference in the score of SASRQ and each dimension in different trauma types (F=68.516, 44.464, 59.725, 48.966, 54.827, P<0.001), the acute stress symptoms were severer in the traffic accident patients group than in the other groups. There was significantly differ-ence in the score of SASRQ and each dimension in different trauma degrees (F=63.584, 69.704, 51.569, 43.669, 33.911, respectively, P<0.001), the acute stress symptoms were lighter in the lighter group than in the other groups. Conclusion There is a high incidence and clear gender and age differences of ASD in patients with traumatic fracture.

Objective To investigate the correlation between the inflammatory-nutritional index (INI) and recurrence and prognosis in patients with gastric cancer. Methods A total of 78 cases patients of gastric cancer with recurrence and 64 cases without recurrence were enrolled. INI was calculated by the ratio of serum albumin and C-reactive protein. The value of INI predicting recurrence was analyzed using receiver operating characteristic curve (ROC). According to this value, the Kaplan-Meier curves and Cox regression analysis were used to evaluate the effect of INI on prognosis. Results Compared with the control group, the recurrence group showed smaller INI, larger tumors, lower degree of differentiation, deeper invasion and higher TNM stage, the differences were statistically significant (all P < 0.01); The INI significantly predicted the recurrence of gastric cancer, with a sensitivity of 62.5%, specificity of 79.5% and critical value of 0.36 (P < 0.01); Additionally, The pathological features were worse in the low INI group than the high INI group , the differences were statistically significant (P < 0.01); The INI significantly predicted the prognosis of gastric cancer, with a sensitivity of 65.9%, specificity of 66.8% and the critical value of 0.34 (P < 0.01); Obviously, the survival rate was lower in the low INI group than the high INI group (48.8% vs 25.0%, P < 0.01). Furthermore, INI was an independent risk factor for prognosis of gastric cancer (OR = 1.78, 95% CI: 1.34 ~ 2.59, P < 0.01). Conclusion The INI is closely related to the characteristics of gastric cancer, it is an effective marker to predict recurrence and prognosis of gastric cancer.

Meshes or prostheses for hernia repair have been developing for half a century, while the best material is far away from being found.Although a few of disadvantages have been made up with products updating, new problems with usage have still arisen.In this review, development process of the repair materials for hernia was summarized and explored.

Atrial fibrillation is the most common arrhythmia in clinical practice.However,the therapeutic effects of traditional antiarrhythmic medicines are far from satisfactory,because of the high rate of arrhythmia recurrence and the potential proarrhythmia effect.Recently,with the further investigation of the mechanisms that initiate and perpetuate atrial fibrillation,and the support of extensive data from clinical trials and animal experiments,thera-peutics based on anti-inflammation,antioxidation,regulation on renin-angiotensin-aldosterone system(RAAS)and gap junction may be new therapeutic targets for the treatment of arrhythmia.In this paper,the potential molecular mechanisms involved in these processes and several clinical trials about some non-traditional antiarrhythmic medi-cines were reviewed,in order to propose a new idea about the development of antiarrhythmic medicines.
