Objective To observe the change of nitric oxide(NO) and superoxide dismutase(SOD) in the epileptic rat brain cortex, and study the effect of the redox states of NO on epilepsy.Methods Using epileptic rat model induced by bemegride, the level of NO and the activity of SOD were measured in rat cerebral motor cortex during and only after seizures.Results The level of NO in rat cerebral motor cortex was significantly increased during and only after seizures than the normal controls. During seizures, SOD activity was decreased; but only after seizures, SOD activity was significantly increased.Conclusion The value of SOD activity than NO content had significantly difference in rat cerebral cortex between during and only after transient seizures. These results suggested that the different redox state of NO would play different role du ring the seizure.

Objective To investigate the changes of plasma bone morphogenetic protein-4 (BMP-4) levels in patients with coronary heart disease (CHD) and rosuvastatin intervention effect on BMP-4 level.Methods Fifty-two patients with CHD and 35 health people were enrolled in this study as CHD group and control group.ELISA method was used to detect the concentration of plasma BMP-4.Analyzed the relationship between plasma BMP-4 and blood lipids,flow-mediated dilation (FMD),nitric oxide (NO),cyclooxygenase-2 (COX-2),malondialdehyde (MDA) and superoxide dismutase (SOD).And observed the changing of plasma BMP-4 before and after rosuvastatin intervention.Results Plasma BMP-4 level in CHD patients was (7.53 ± 1.20) μg/L,higher than that of control group ((3.81 ± 0.79) μ g/L,t =3.541,P =0.006).After rosuvastatin treatment,plasma BMP-4 level in CHD patient was decreased from (7.53 ± 1.20) μg/L to (5.40± 0.98) μg/L (t =1.436,P =0.001).Plasma BMP-4 level was positively correlated with COX-2,MDA,low-density lipoprotein cholesterol,total cholesterol (r =0.395,0.350,0.274,0.288 respectively,P ＜ 0.01 or P ＜0.05).But,it was negatively correlated with NO,high-density lipoprotein cholesterol,SOD,FMD (r =-0.291,-0.253,-0.476,-0.320 respectively,P ＜0.01 or P ＜0.05).COX-2,SOD and FMD were independent risk factors of plasma BMP-4 in patients with CHD.Conclusion Oxidative stress and endothelial dysfunction are in patients with CHD.Rosuvastatin treatment can remarkably reduce plasma BMP-4 level,alleviate vascular endothelium injury induced by oxidative stress and improve endothelial function in patients with CHD.

Objective To investigate the mechanism of brain derived neurotrophic factor (BDNF) regulated by differ-ent isoforms of tyrosine kinase receptor B (TrkB) in epileptic hippocampal neurons. Methods Primary hippocampal neu-rons were cultured in vitro for 7 days, and divided into two groups, ALLN (calcineurin inhibitor) group and Anisomycin (trans-lation inhibitor) group. ALLN group included control group, control+BDNF group, epilepsy group, epilepsy+BDNF group, control+ALLN group, epilepsy+ALLN group and epilepsy+ALLN+BDNF group. Anisomycin group was sub-divided into con-trol group, control+BDNF group, epilepsy group, epilepsy+BDNF group, control+Anisomycin group, epilepsy+Anisomycin group and epilepsy+Anisomycin+BDNF group. The immunofluorescent technique was used to identificate the hippocampal neurons. Epileptiform discharges were detected by electrophysiological techniques. Western blot assay was used to deter-mine the protein expression of TrkB and phosphorylated TrkB (p-TrkB) in all cell groups. Results (1) In ALLN group, the gray value of p-TrkB/TrkB was higher in control+BDNF group compared with that of control group, the value was higher in epilepsy+BDNF group than that of epilepsy group but was lower than that of control+BDNF group. The gray value of p-TrkB/TrkB was lower in epilepsy+ALLN+BDNF group than that of epilepsy+BDNF group, but no significant difference compared with that of epilepsy+ALLN group. (2) In Anisomycin group:the gray value of p-TrkB/TrkB was higher in control+BDNF group than that of control group. The gray value of p-TrkB/TrkB was higher in epilepsy+BDNF group than that of epilepsy group, but which was lower than that of control+BDNF group. The gray value of p-TrkB/TrkB was higher in epilepsy+Aniso-mycin+BDNF group than that of epilepsy+BDNF group and epilepsy+Anisomycin group. Conclusion The decreased ex-pression of TrkB.T can improve the inhibition of BDNF/TrkB signaling, and BDNF can activate BDNF/TrkB signal pathway in epileptic hippocampal neurons. The increased TrkB.FL protein level by ALLN can’t improve the inhibition of BDNF/TrkB signal pathway.

Objective To investigate the clinical value of the combination of routine magnetic resonance imaging (MRI),magnetic resonance cholangiopancreatography (MRCP),diffusion weighted imaging (DWI)and enhanced magnetic resonance imaging in the diagnosis of recurrent pyogenic cholangitis (RPC).Methods The clinical and MRI data of 2 1 cases of RPC confirmed by surgery or puncture were retrospectivly analyized.Results All of 2 1 patients were performded with routine MRI (FSE T2 WI,FSPGR T1 WI and FIASTA),MRCP and DWI.1 2 cases were underwent three-dimensional dynamic contrast-enhanced MRI with a liver volume accelerated acquisition sequence (LAVA).The raw data was uploaded to GE ADW4.4 station and the three dimensional MRCP and DWI were analyzed.(1)All of 21 cases were hepatolithiasis complicated with irregular expansion.11 cases were involved left intra-hepatic bile duct,7 cases were right intrahepatic duct,and 3 cases were involved left and right intrahepatic bile duct.Wall thickening was in 19 cases,normal biliary duct wall was in 2 cases.(2)Common bile duct disease:calculus of intrahepatic and extrahepatic bile duct complicated with bile duct dilatation were in 8 cases.Calculus of intrahepatic bile duct were individually in 13 cases.(3)Gall-bladder disease:there were 5 cases of gallstone,9 cases of chronic cholecystitis,3 cases of acute cholecystitis and 4 cases of chole-cystectomy.(4)Liver parenchyma disease:there were 6 cases of liver atrophy in all the cases (left lobe atrophy of 4 cases,right lobe atrophy of 4 cases).The inflammatory changes around dilated bile ducts were found in 1 2 cases.The MRI findings of those were slight patchy hyperintensity signal on conventional T2 WI,the area of hyperintensity signal on T2 WI was extended on DWI.On dynamic contrast-enhanced MRI,the inflammatory areas were uniformity minor enhancement on arterial phase,and hardening in-creases on portal and delayed phase.Conclusion Multi-sequences MRI can be more fully reflected the pathologic changes of RPC, which is important for imaging diagnosis of the disease.

Objective To study the effect of miR-204 on BDNF/TrkB signaling and pathogenesis on the neuron model of epilepsy. Methods Primary hippocampal neurons were cultured in vitro for 7 days, and were divided into control group, control+BDNF group, epilepsy group, epilepsy+BDNF group , control+miR204 group, epilepsy+miR204 group and ep-ilepsy+miR204+BDNF group. The epilepsy model of hippocampal neurons was established by being exposed to Mg2+free me-dia for 3 hours. The miR-204 lentivirus vector was constructed. The effect of miR-204 on BDNF/TrkB expression was detect-ed by immunohistochemistry, patch clamp and Western blot technique. Results Compared with the control group, the TrkB phosphorylation level was higher in control+BDNF group. The TrkB phosphorylation level was lower in epilepsy+BDNF group than that of control+BDNF group, but it was higher than that of epilepsy group. The TrkB phosphorylation level was higher in epilepsy+miR204+BDNF group than that of epilepsy+BDNF group and epilepsy+ miR204 group. Conclusion BDNF and miR-204 can improve the inhibitory condition of BDNF/TrkB signaling and may play an important role in alleviat-ing epilepsy disease.

Staphylococcus aureus ( S. aureus ) osteomyelitis, a significant complication for patients un-dergoing fracture fixation, is a great challenge for orthopaedic surgeons due to its extreme difficulty in mangae-ment. Animal models play an important role in exploring the pathogenesis of osteomyelitis and determining the efficacy of prophylactics and therapeutic treatment. To help understand current animal models of S. aureus os-teomyelitis, we conduct a systematic search to identify animal experiments that have investigated the management of S. aureus osteomyelitis. Experimental studies are categorized by animal species and are further classified by the setting of infection. Study methods are summarized and the advantages and disadvantages of each species and model are discussed.

Objective Preoperative preparation of blood is common.The preoperative blood ordering and transfusion practices for elective obstetric surgery were evaluated in our Renji hospital in order to develop a reasonable preoperative blood preparation schedule for those procedures where a cross-match appears necessary.Methods We evaluated blood ordering practices in total 16 232 elective obstetric surgeries in our hospital from January 1,2013 to June 30,2017 retrospectively.The age of patients,preoperative diagnosis,surgical procedures type,preparation volume of blood,intra-operative transfusion volume of blood,and excessive usage ratio of blood were calculated and analyzed.Results 455 patients transfused intraoperatively total 1 610 U red blood cells.The usage ratio of blood was 2.80％ for patients and 4.87％ for blood preparation volumes respectively.Placenta previa,ectopic pregnancy,twin pregnancy accounted for the first three of the possibility of intraoperative blood transfusion in obstetric surgeries.Conclusion The relationship between preoperative diagnosis and the risk of blood transfusion in obstetric surgery should be take attention to.Preoperative blood typing,antibody screening and appropriate cross-matching could ensure the safety of obstetric surgery.

Multidrug resistance (MDR) is one of the main causes leading to the failure in cancer treatment. Differential proteins between esophageal squamous cell carcinoma (ESCC) cell line EC9706 and its cisdiamminedichloroplatinum (CDDP)-resistant subline EC9706/CDDP revealed by quantitative analysis may provide deeper insights into the molecular mechanisms of MDR implicated in ESCC. EC9706/CDDP was generated by exposure of its parental sensitive EC9706 to a step-wise increase of CDDP concentration during EC9706 cultivation. The stable isotope labeling with amino acids in cell culture (SILAC) was used to label EC9706 and EC9706/CDDP with heavy and light medium, separately. Mixed peptides derived from EC9706 and EC9706/CDDP were analyzed by high performance liquid chromatography-electrospray ionization-mass spectrometry (HPLC-ESI-MS/MS) and subsequently subjected to bioinformatics analysis to identify differential proteins between EC9706 and EC9706/CDDP. Compared to parental EC9706, EC9706/CDDP manifested phenotypes of slow proliferation, cell pleomorphology, atypia and increased resistant-index 3.23. Seventy-four differential proteins identified in the present study belongs to various families with multiple functions, such as cytoskeleton (20%), energy metabolism (11%), transcription regulation and DNA repair (11%), redox homeostasis (9.5%), protein biosynthesis and mRNA processing (12%), ribosome constituent (8.1%), molecular chaperone (8.1%), immunity/inflammation (5.4%), intracellular transport (5.4%) and nucleosome assembly (2.7%), which indicated that development of MDR is a complicated process involving dysregulation of multiple molecules and pathways. The data is of great value for in-depth elucidation of molecular mechanisms of the MDR implicated in ESCC and may represent potential molecular targets for future therapeutic development.
