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.

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.

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 investigate the value of brain natriuretic peptide (BNP) in differentiating acute dyspnea from aged pa-tients with heart failure. Methods The concentration of plasma BNP was measured with immunofluorescence assay in 145 aged patients with dyspnea who admitted to hospital by emergency or were out - patients. Results The BNP level in patients with dyspnea caused by heart failure was significantly higher than that of lung disease patients. BNP for the diagnosis of left heart failure had a very strong predic-tive value, while the early diagnosis of pulmonary heart disease and right heart failure has yet to be explored. BNP values > 100ng / L for differentiating of heart failure was the following: the sensitivity of diagnosis was 94.1%, accuracy 93. I%, specificity 79.5%, positive predictive value was 91.3%, and negative predictive value was 85.4%. Conclusion BNP assay was a convenient, rapid and sensitive method for differentiating diagnosis in aged patients with heart failure, especially with left heart failure. It can be used as an important dif-ferential method in elderly patients with acute dyspnea.

Objective To investigate the diagnostic value of Lugol solution staining combined with nar-row band imaging (NBI)for esophageal cancer and precancerous lesions.Methods From December 201 3 to December 2014,1 87 patients who were with suspicious esophageal lesions and stained with Lugol solution under endoscopy were selected as control group,while from January 2015 to June 2015,124 patients who were with sus-picious esophageal lesions and examined with Lugol solution staining and NBI under endoscopy were selected as observation group.The sensitivity,specificity and accuracy between the two groups were compared and analyzed. Results One hundred and four cases (75.0%)were found among observation group,which was higher than 93 cases (55.6%)among control group (χ2 =12.07,P <0.01 ).The total detection rates of esophageal cancer and high grade intraepithelial neoplasia (HGN)were 29.0% and 17.7% in observation group respectively,which were higher than 1 8.2% and 6.4% in control group (χ2 =4.15,P =0.04;χ2 =8.54,P <0.01 ).The Kappa value in observation group was 0.55,which was higher than 0.36 in control group.The sensitivity and accuracy in observation group were 89.9% and 82.3% respectively,which were significantly higher than 71 .8% and 68.4% in control group (χ2 =9.79,P <0.01 ;χ2 =7.38,P <0.01 ).Conclusion The sensitivity and accuracy of endoscopic Lugol solution staining combined with NBI for esophageal cancer and precancerous lesions are higher than Lugol solution staining,and it is worthy to popularize the application of Lugol solution staining com-bined with NBI in diagnosing esophageal cancer and precancerous lesions.

As a rational economic man and agent, in the primary care Physicians not only pursue target in-come, but also pursue the utility of the agent. Different health care payment has different effect on physician, due to imperfect physician agent of the primary health care, the health care payment is difficult to achieve economic neutral. Based on the theory of target income and physician-induced demand, the paper proves that in the primary health care with the third party payment, there should be a prospective component of payment and fees should be lower than mar-ginal cost, which can not only improve the role of agent, but also constraint the physician-induced demand, so as to achieve health care for physician’s behavior constraints.
