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.

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.

Objective To analyze the effect of CO2 laser under suspension laryngoscope on patients with vocal cord polyp. 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.

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 .

Objective To observe the changes of plasminogen activator inhibitor-1(PAI-1)mRNA expression in experimental lung iniury and to evaluate the effect of inhaled nitric oxide(NO)on PAI-1 mRNA expression.Methods In this study,acute lung injury rat model was established by lipopolysaccharide(LPS)-induced endotoxemia followed by a second LPS attack via intratracheal injection.Eighty-nine SD male rats aged 4～5 week were randomly assigned to three groups:saline control(C-A)group,LPS-A group attacked by LPS,LPS-NO group treated by nitric oxide.Realtime PCR was used to study the expression of PAI-1 mRNA in the lung.Histopathological lung injury score was evaluated.Results In LPS group,the histopathological lung injury score values were significantly higher than that of C-A group at 2 h[(3.10±0.38)vs(1.12±0.84)](P＜0.05)and the score values after 2 h were higher than that of LPS group at 2 h(P＜0.05).PAI-1 mRNA in lung increased gradually in LPS groups at 2 h,4 h,8 h,16 h,24 h(P＜0.05)and decreased at 48 h(P＞0.05).The PAI-1 mRNA decreased in LPS-NO groups at 4h(P＜0.05).Conclusion The study above demonstrates that PAI-1 mRNA expression is early elevated in rats with endotoxin-induced acute lung injury.Decreased PAI-1 mRNA expression is associated with the efficacy of inhaled nitric oxide.

Objective To determine the efficiency of cervical length by transvaginal sonography combined with serum relaxin for predicting premature birth.Methods The study enrolled 280 single births primipara.Cervical length was measured by transvaginal sonography during mid-trimester and late-trimester of pregnancy.Serum relaxin was measured during mid-trimester of pregnancy,late-trimester of pregnancy and postpartum.Sensitivity of cervical length,serum relaxin and cervical length combined with serum relaxin were applied for predicting premature birth.Results The sensitivity of cervical length and serum relaxin during mid-trimester of pregnancy for predicting premature birth were 54.43％ and 57.72％,respectively.The sensitivity of cervical length and serum relaxin during late-trimester of pregnancy for predicting premature birth was 62.74％ and 66.49％,respectively.Sensitivity of cervical length and serum relaxin during late-trimester of pregnancy for predicting preterm birth were more satisfying than those during mid-trimester of pregnancy.The sensitivity of cervical length combined with serum relaxin for predicting premature birth were 70.76％ and 71.51％,which were obviously higher than those obtained using cervical length or serum relaxin alone.Conclusion The combination of cervical length and serum relaxin can significantly improve the sensitivity of predicting premature birth,which can diagnose premature birth early and exactly.
