The epilepsy symptom and the pia microcirculatory blood flow volume (PMBFV) were investigated in epilepsy rat model induced by strychnine and the changes after treatment by using faradized frequency spectrum therapeutic equipment were observed. The epilepsy symptom was improved and the PMBFV increased after treatment. The convulsion seizure time was delayed, the seizure frequency and convulsion time were reduced, and the epilepsy even was not appeared in some cases. Results suggested that this improvement might be related to the change of PMBFV.

OBJECTIVETo investigate the effects of injecting adenosine A1 receptor agonist (CCPA) into Baihui (GV20) on the cerebral cortex induced by the ischemia/reperfusion of middle cerebral artery occlusion (MCAO) in rats.
METHODSTwenty-four SD rats were randomly divided into four groups, i. e., the sham-operation group, the model group, the DMSO group, and the CCPA group. The MCAO model was established by thread embolism method. At the moment of ischemia/reperfusion, the rats in DMSO group and the CCPA group were injected with DMSO (20 microL) and CCPA (0.1 mmol) 20 microL into Baihui respectively. The rats' behavior, the histomorphology of ischemic penumbra in the cerebral cortex, the expressions of Bcl-2 protein, and the apoptosis rate of neurocytes were assessed.
RESULTSCompared with the model group and the DMSO group, the rats' behavior were markedly improved in the CCPA group (P<0.05). No obvious karyopyknosis and cytoplasm empty dye of neurons appeared. The Bcl-2 expressions in rats' cerebral cortex obviously increased (P<0.01). The apoptosis number of neurons obviously decreased (P<0.01).
CONCLUSIONSInjecting CCPA into Bahui improved the rats' behavior and histomorphology in the ischemic penumbra, elevated the expressions of Bcl-2 protein, and reduced the neurons apoptosis rate in the ischemic penumbra. It alleviated the cerebral ischemia-reperfusion injury. Therefore, it could be taken as a new treatment method.

A bacterial strain which could grow well on the substrate of PAEs as the sole source of carbon and energy was isolated from contaminated sludge in the river of WeiFang in ShangDong province and it was designated as JDC-3. Based on the morphology,biophysical and biochemical properties as well as molecular characteristics,this isolate was preliminarily identified as Delftia sp.. A fragment of phthalate dioxygenase gene was successfully amplified from the genus of Delftia for the first time using a set of degenerate primers. Meanwhile,the degradation capability of JDC-3 was determined by HPLC using DMP as test substrate. The results showed that the optimal pH and temperature were at 7.0~8.0 and 30?C~35?C respectively. The degradation kinetics of JDC-3 was studied in different initial DMP concentration under optimal conditions. The results indicated that the degradation dynamic equation was ln C =-0.06837 t + A when DMP concentration was lower than 300 mg/L,with half life of 12.48 h. The degradation rate decreased and half life of JDC-3 prolonged as the initial concentration kept on increasing.

OBJECTIVETo observe whether adenosine Al receptor (Al R) mediated neuroprotection of Shenmai Injection (SI) on rat cerebral ischemia/reperfusion (I/R) injury.
METHODSThe focal cerebral I/R model was established by middle cerebral artery occlusion (MCAO). Totally 60 successfully modeled rats was divided into 5 groups according to randomized block principle, i.e., the model group, the SI group, the SI + AlR antagonist (1,3-dipropyl-8-cyclopentylxanthine, DPCPX) group, the AlR antagonist control group, and the dimethyl sulfoxide (DMSO) control group, 12 in each group. Besides, a sham-operation group was set up (n =12). SI at 15 mL/kg was peritoneally injected to mice in the SI group immediately after cerebral I/R. Equal volume of normal saline was injected to mice in the model group and the sham-operation group. DPCPX at 1 mg/mL was peritoneally injected to mice in the Al R antagonist control group 30 min before peritoneal injecting SI. DPCPX at 1 mg/kg and DMSO at 1 mL/kg were peritoneally injected to mice in the AlR antagonist control group and the DMSO control group 30 min immediately before cerebral I/R. Rats' neurobehavioral scores were assessed after 24 h reperfusion. The volume of cerebral infarction and Bcl-2 protein expression of cerebral infarction penumbra were also detected. Results Compared with the sham-operation group, neurobehavioral scores, the volume of cerebral infarction, and Bcl-2 protein expression increased (all P <0. 05). Compared with the model group, neurobehavioral scores and the volume of cerebral infarction obviously decreased, but Bcl-2 protein expression increased in the SI group (all P <0. 05). Compared with the SI group, neurobehavioral scores increased, the volume of cerebral infarction was obviously enlarged, and Bcl-2 protein expression was obviously reduced in the A1R antagonist control group (all P <0. 05).
CONCLUSIONSSI's neurobehavioral scores could be partially reversed in the Al R antagonist control group, the volume of cerebral infarction and Bcl-2 protein expression improved. AlR might possibly meditate neuroprotection of SI on MACO mire

OBJECTIVETo investigate the effects of Newcastle disease virus (NDV) infection on the expression of survivin and cell cycle in human tongue squamous carcinoma TSCCa cells.
METHODSThe proliferation of TSCCa cells infected with NDV in vitro was evaluated by means of MTT assay, and survivin expression in the infected cells was detected using RT-PCR and Western blotting. Flow cytometry was performed to assess the changes in the cell apoptosis, cell cycle and cell proliferation index (PI) of the cells.
RESULTSNDV infection resulted in decreased survivin expression and increased apoptosis of TSCCa cells, with reduced cell percentage in G2/M and S phases and lowered PI of the cells, showing significant differences from those of the negative control cells (P<0.05).
CONCLUSIONNDV infection can inhibit survivin expression, affect the cell cycle of TSCCa cells and induce their apoptosis.

Objective To explore the efficacy and safety of Solitaire stents and the multi-mode vascular recanalization in the treatment of acute cerebral infarction. Methods Twenty-two patients with acute cerebral infarction, who were treated by Solitaire stents and the multi-mode vascular recanalization (research group) in our hospital from November 2014 to February 2017, were included in this study. Among them, 16 cases were combined with balloon dilation after arterial thrombosis, 4 cases were given stent implantation (3 cases were given Solitair stent and 1 case was given Apollo stent), and 2 cases were given arterial catheter directed thrombolysis. Eighteen patients with acute cerebral infarction who were treated only by Solitaire stent artery occlusion from October 2011 to October 2014 were used as control group. Data of the onset to the vagina vasorum time, the onset to the recanalization time, the revascularization of interventional therapy, the NIHSS scores at admission and discharge, mRS score after 90-day treatment, incidence rate and the mortality were compared between two groups. Results There were no significant differences in the durations from onset to the vagina vasorum and from the onset to the recanalization between the two groups. The recanalization was better in research group than that of control group (P<0.05). There were no significant differences in scores of NIHSS at hospital discharge and admission between two groups. The near-term treatment efficacy was similar in two groups. However, mRS score was significantly lower in the research group than that in control group after 90-day treatment (P<0.05). There were no significant differences in the symptomatic intracranial hemorrhage, high perfusion encephalopathy, the incidence rate and the mortality rate of the complications related to the operation between two groups of patients. Conclusion Solitaire stents and the multi-mode vascular recanalization can significantly improve the revascularization, the further clinical prognosis and the quality of survival in patients with acute cerebral infarction, which are safe and efficacy without increasing incidence rate and mortality rate of complications.
