Objective To evaluate the neuroprotective effect and possible mechanisms of edaravone(3-methyl-1-phenyl-2-pyrazolin-5-one) in neonatal Harlequin(Hq) mutant mice brain after hypoxia-ischemia brain injury(HIBD) insult.Methods The nine-day-old male Hq mutant mouse pups were assigned randomly either edaravone(n=16) and vehicle(n=17) treatment group.The Hq mice were subjected to left common carotid artery occlusion combined with inhalation 100 mL/L oxygen for 45 minutes.The mice were injected intraperitoneally either with edaravone(10 mg/kg) or equivalent volume of saline immediately after artery occlusion and after hypoxia.Nitrotyrosine and lipid peroxidation formation were evaluated at 3 h and 24 h after hypoxia-ischemia(HI) by using immunohistochemistry staining.Nitrotyrosine formation and caspases activation were evaluated either by immunoblotting or fluorogenic activity measurement at 24 h after HI.Brain injury was evaluated at 72 h by neuropathological score and calculating the infarct volume.Results Brain injury encompassed cortex,hippocampus,striatum and thalamus.Edaravone treatment reduced brain injury significantly in all the brain regions.The total infarct volume was reduced 52.8% in edaravone treatment group compared with vehicle group(P

Edaravone treatment reduced brain injury significantly in all the brain regions. The total infarct volume was reduced 52.8% in edaravone treatment group compared with vehicle group (P<0.001). The edaravone treatment reduced nitrotyrosine formation as well as lipid peroxidation formation significantly, but without obviously effect on caspases activation.ConclusionEdaravone affords neuroprotection after neonatal HI insult, which correlated with the reduction of free radical formation.

Objective : To understand the current situation and characteristics of narcotic drugs and psychotropic drugs abuse or dependence among hospital patients and to provide reference for strengthening the management of narcotic drugs and psychotropic drugs. Methods : We collected clinical data from hospitals in Shandong and Guizhou provinces in 2016 and selected patients with history of narcotic drugs and psychotropic drugs. We investigated them through telephone or face-to-face interview,then described the characteristics of demographic information and abuse or dependence of narcotic drugs and psychotropic drugs in diagnosed drug abusers. Results : A total of 280 patients with drug abuse or dependence were recruited,of which 223 cases from nine hospitals in Shandong and 57 cases from five hospitals in Guizhou. There were 170 male patients,accounting for 60.71%; 193 patients aged 45 years and above,accounting for 68.93%; 223 married patients,accounting for 80.51%; 166 patients with a education level of junior high school and below,accounting for 61.25%; 125 patients engaged in agriculture,accounting for 48.64%. Benzodiazepine was the main drugs abused or dependenced by hospital patients,accounting for 73.57%（206 cases）. There were also 83 cases of polydrug abuse,accounting for 29.64%. Among the patients with drug abuse or dependence,45.71% had no special feelings,41.07% had symptoms or felt uncomfortable after withdrawal; 64.64% was for improving their sleep quality. Conclusion Most patients with abuse or dependence of narcotic drugs and psychotropic drugs are middle- or senior-aged and have polydrug abuse. Benzodiazepine are the main abused drugs. The common reason for narcotic and psychotropic drug abuse or dependence is to have a good sleep.

Objective To investigate the clinicopathology and immunophenotype of primary non- Hodgkin lymphoma(NHL)of the female genital system,and to analyze the prognosis of such tumors. Methods Clinicopathologic features of 43 cases of primary NHL of the female genital system were studied retrospectively,with the histological classification based on the Classification of Haematopoietic and Lymphoid Tumors(WHO,2001).Immunochemistry technique,in-situ-hybridization and polymerase chain reaction methods were used to detect the immunophenotype,epstein barrvirus(EB)virus infection status and immunoglobulin heavy chain gene rearrangement,respectively.Results(1)Primary lesions:there were 24 cases of lymphoma originating in the ovary,3 cases in the endometrium,10 cases in the cervix,2 cases in the vagina and 4 cases in the vulva.(2)Staging:12 cases(28%)were in stage Ⅰ,9 cases (21%)in stage Ⅱ,and 22 cases(51%)in stage Ⅲ.(3)Histological classification:37 cases(86%)were diffuse large B cell lymphoma(DLBCL),3 cases were Burkitt lymphoma and the remaining 3 cases were unspecified peripheral T-cell lymphoma according to biopsy,immunophenotype analysis,in-situ- hybridization technique and IgH gene rearrangement detection.(4)Prognosis analysis:increase in the level of lactic acid dehydrogenase,stage Ⅲ,DLBCL and single operation suggest poor prognosis.Conclusions Establishment of the diagnosis of primary NHL of the female genital system is based on biopsy, immunophenotype analysis,in-situ-hybridization technique and IgH gene rearrangement detection,which play important roles in diagnosis and differential diagnosis of the tumor.Combined therapy is the first choice of therapeutic regimens.

Objective To investigate the effect of Ulinastatin on the delivery of cytokines in patients with septic shock.Methods It was a prospective and controlled clinical study.Seventy-eight patients with septic shock were randomly divided into control group and treatment group and thirty-nine in every group.Patients in treatment group received Ulinastatin 200 000 units intravenous everyday for 3 days,while those in control group received equal volume of normal saline as placebo.At different time points (at 24 th,48 th,72 th hour after start of treatment),the levels of tumor necrosis factor-alpha (TNF-?),interleukin-1 (IL-1),interleukin-6 (IL-6 ),interleukin-8 (IL-8) and superoxide dismutase (SOD) in serum were assayed.Results In comparison with control group,the levels of TNF-?,IL-1,IL-6,IL- 8 of treatment group decreased markedly (P＜0.05,P＜0.01) at different time points,whereas the level of SOD was higher markedly (P＜0.05,P＜0.01) at various time points.Conclusion Ulinastatin has protective effect on patients with septic shock through decreasing the levels of TNF-?,IL-1,IL-6,IL-8 and increasing in the level of SOD.

Objective To investigate whether elevated pre-procedural C-reactive protein (CRP) and Interleukin-6 (IL-6) concentrations may be relevant to early outcome in patients undergoing PCI.Method 100 consecutive patients undergoing pereutaneuous coronary intervention (PCI) were included in our study.Peripheral blood samples for CRP and IL-6 testing were withdrawn before PCI.Acute vascular complications resulted from PCI were determined by subsequently coronary angiography.The early coronary events during hospitalization were clinically followed.Results Thirty patients developed acute vessel occlusion,and another one developed subacute coronary thrombosis at 2 days after PCI.Increased levels of CRP correlated well with the occurrence of vascular complications as regards the significant difference existing amongⅠvsⅢandⅠvsⅣquartile groups,P

To construct the Bac-to-Bac expression system of Bombyx mori nucleopolyhedrovirus (BmNPV), a transfer vector was constructed which contained an Escherichia coli (E. coli) mini-F replicon and a lacZ: attTN7: lacZ cassette within the upstream and downstream regions of the BmNPV polyhedrin gene. B. mori larvae were cotransfected with wild-type BmNPV genomic DNA and the transfer vector through subcutaneous injection to generate recombinant viruses by homologous recombination in vivo. The genomic DNA of budded viruses extracted from the hemolymph of the transfected larvae was used to transform E. coli DH10B. Recombinant bacmids were screened by kanamycin resistance, PCR and restriction enzyme (REN) digestion. One of the bacmid colonies, BmBacJS13, which had similar REN profiles to that of wild-type BmNPV, was selected for further research. To investigate the infectivity of BmBacJS13, the polyhedrin gene was introduced into the bacmid and the resultant recombinant (BmBacJS13-ph) was transfected to BmN cells. The budded viruses were collected from the supernatant of the transfected cells and used for infecting BmN cells. Growth curve analysis indicated that BmBacJS13-ph had a similar growth curve to that of wild-type BmNPV. Bio-assays indicated that BmBacJS13-ph was also infectious to B. mori larvae.
