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.

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.

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.

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.

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 .

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.

AIM\ To study whether total astragalosides(TA) induces apoptosis in human hepatoma cells and its mechanism of action. METHODS\ The human hepatoma HepG2 and Bel 7404 were cultured with TA (20,40 and 80 mg?L -1 ) for 6 days and DNA fragmentation and the expression of wtp53 protein were determined by flow cytometry. RESULTS\ HepG2 and Bel 7404 cell apoptosis induced by TA(20,40 and 80 mg?L -1 ) were found by flow cytometry. The apoptotic peak of HepG2 cells increased in dose dependent manner in the range from 4 1% to 74 5%; The apoptotic peak of Bel 7404 cells also increased from 4 5% to 50 5%. The expression of wtp53 in HepG2 cells and Bel 7404 cells treated with TA (80 mg?L -1 ) were upregulated. CONCLUSION\ TA may induce apoptosis in HepG2 cells and Bel 7404 cells, its mechanism of action might be associated with upregulating the expression of wtp53.

Objective To explore the levels of serum adiponectin(APN)and homocysteine(Hcy)in elderly patients with type 2 diabetes metlitus(T2DM)complicating retinopathy and the relation between these two indicators.Methods Sixt-eight cases of complicating retinopathy(T2DM+DR group)were screened from the elderly inpatients with T2DM in our hospital from January 2012 to December 2014.Their general data were investigated.The routine biochemical indicators were tested.The enzyme-linked immunosorbent assay(ELISA)was employed to measure the serum total APN,high molecular weight APN and Hcy levels.Mean while the correlation among total APN,high molecular weight APN and Hcy was evaluated by adopting the Pearson correlation analysis.Contemporaneous 65 cases of elderly T2DM and 70 elderly people undergoing the healthy physical examination were chosen as the T2DM group and NC group respectively.Results The WHR,FBP,TC,TG,LDL-C,HbA1c,FINS and HOMA-IR in the T2DM+DR group and T2DM group were higher than those in the NC group,while the HDL-C level was lower than that in the NC group(P＜0.05);the duration and BMI of the T2DM-4-DR group were higher than those of the T2DM group,the difference was statistically significant(P＜0.05);the levels of total APN and high molecular weight APN in the T2DM+DR group and T2DM group were lower than those in the NC group,while the Hcy level was higher than that in the NC group(P＜0.05);moreover the levels of total APN and high molecular weight APN in the T2DM+DR group were lower than those in the T2DM group,and Hey level was higher than that in the T2DM group,the difference was statistically significant(P＜0.05);the levels of total APN(r=-0.654)and high molecular weight APN(r=-0.562)were negatively correlated with the Hey level in the T2DM+DR group(P＜ 0.05).Conclusion The serum APN level is decreased and Hcy level is increased in elderly patients with T2DM complicating retinopathy,which may be associated with the progression of retinopathy in T2DM.

One pathogenic free-living amoeba, strain W042302 (Fig. 1.), was first isolated from the cooling water of a power plant in Shanghai, in April, 1986. It could result in the deaths of mice, and recovered from the brain tissue of the dead mice. This pathogenic free living amoeba could be induced into trophozoite with two flagellae (Fig. 2.). Protein patterns obtained by PAGE showed twelve bands stained by Coomassie brilliant blue R250. The isoenzyme patterns of both acid phosphatase and alkaline phosphatase of the amoebic extract exhibit only a single band, while iactate dehydrogenase is devoid of noticeable activity. From the results obtained in the present study, it is inferred that strain W042302 may be belong to Naegleria australiensis.
