Histone deacetylase (HDAC) is a protease which regulates gene expression and modify the structure of chromosome. The balance between acetylation and deacetylation of histone plays an important role in maintaining cellular function and the process of genes expression. Overexpression of HDAC and recruitment by transcription factors inhibit the expression of certain genes, leading to tumorigenesis and other diseases. Recently, with the further research on cancer epigenetics, HDAC inhibitors have increasingly caught attention. As a novel class of antitumor agents, HDAC inhibitors are widely explored in hematological malignancies. There are several kinds of HDAC inhibitors for the treatment and clinical research of non-Hodgkin lymphoma (NHL), such as vorinostat, belinostat, chidamide, CUDC-907. This article mainly describes the development of the HDAC inhibitors in NHL.

Objective To investigate the efficacy of amplitude-integrated electroencephalographic (aEEG)in evaluating the maturation of cerebral function in preterm infants.Methods Ninety one neurologically normal and clinically stable preterm infants admitted to neonatal intensive care unit were studied prospectively by using aEEG.Background of aEEG activity patterns,presence of sleep-wake cycles,and the lower and higher border were analyzed.Results 112 aEEG were analyzed.The sleep-wake cycle and the continuity became more mature with PMA increased.The lower border were increased and the higher border were decreased with PMA increased(r =0.982,P ＜ 0.01 ; r =-0.964,P＜0.01).Conclusion In preterm infants,aEEG is a useful tool to evaluate the maturation of cerebral function.

Objective To investigate the present situation and outcome of cardiopulmonary resuscitation (CPR) for pediatric in-hospital cardiopulmonary arrest and to analyze the prognostic risk factors.Methods Data were collected from October 2008 till October 2011 using Ustein style.Patients older than 28 days who received CPR were evaluated.Returning of spontaneous circulation(ROSC) more than 24 hours was the primary outcome.Neurological outcome was assessed by pediatric cerebral performance categories half year after discharge.Results Of the 36 patients,15 (41.7％) achieved sustained ROSC.Seven (19.4％) patients survived to discharge.Single factor analysis indicated that the beginning heart rhythm,defibrillation and original disease were significantly different between the two groups(P ＜0.05).The beginning heart rote of the patient in ROSC ＞ 24 h group was mostly sinus bradycardia.Patients who need defibrillation had bad prognosis.Patients with heart disease had a lower rate of ROSC ＞ 24 h.At half year follow-up study,4 patients had 1 or 2 score,1 patient had 4 and 1 had 5 score in the pediatric cerebral performance categories scales.Condusion The successful rate of CPR in our hospital was the same as that in developed country.The beginning heart rhythm,defibrillation and original disease were associated with the outcome.Most of the patients who survived to discharge had a good neurological outcome.

Objective To explore the association between human papilloma virus(HPV)infection and antisperm antibodies(As-Ab)in male infertile patients in Xinjiang area.Methods A total of 127 cases of infertile male patients were selected as experimental group,other 130 cases of normal male were enrolled in the control group.HPV sperm infection was detected by using reverse dot blot hybridization kit.The levels of AsAbs in semen specimen were measured by using the enzyme-linked immunosorbent assay (ELISA).Results The infection rate of male infertile patients(67.7%)was higher than that of normal male(1 6.2%),with signifi-cant differences(P <0.05).The positive rate of AsAb of male infertile patients with HPV infection(38.4%)was higher than that of male infertile patients without HPV infection(1 7.1%),with significant differences(P <0.05).Compared with male infertile pa-tients without HPV infection,the percentages of sperm motility and grade (a+b)sperm motility were decreased in male infertile pa-tients with HPV infection,wihile the sperm malformation rate was increased in male infertile patients with HPV infection,with sig-nificant differences(P <0.05).Conclusion The HPV infection rate of male infertile patients is relatively high in this area.HPV sperm infection could be associated with AsAb that may further reduce male fertility.

Objective To investigate the effects of focal mild hypothermia on apoptotic neurons and the expression of glutamate transporter(GLT-1)and metabotropic glutamate receptor(mGluR2/3)after cerebral ischemia in rats.Methods Eighty-eight adult rats were randomly divided into mild hypothermia group,normothermia group and control group.Unilateral permanent middle cerebral artery occlusion(pMCAO)was induced.In mild hypothermia group,the brain temperature of occlusive side was decreased and maintained for 3 h at(33?0.5)℃ with Sticking Focal Mild Hypothermia Instrument.The body temperature of normothermia group was maintained at(37?0.5)℃.3 h,6 h,12 h,24 h,3 d,7 d after cerebral ischemia,the expression of GLT-1 and mGluR2/3 around infarction cortex were determined by Western Blot.6 h,24 h,3 d,7 d after cerebral ischemia,TUNEL method was performed to label neuronal apoptosis.Results 24 h,3 d after cerebral ischemia of mild hypothermia group,24 h,3 d,7 d after cerebral ischemia of normothermia group,the apoptotic neurons around infarction core markedly increased comparing with 6 h after cerebral ischemia(all P

Objective To observe the earlier changes of left heart structure and function in patients with Grade 1 hypertension.Methods 65 patients with Grade 1 hypertension were measured on the left atrial diameter(LAD),left ventricular diameter,thickness of ventricular,mass index and evaluate the left ventricular systolic and diastolic function by UCG.Results Compaired to 50 normal controls,the LAD and left ventricular diastolic function of the patients(38.06?3.68 mm,0.72?0.11) was significantly different with those of 50 normal controls(29.86?3.08 mm,1.18?0.08)(P
