Immunogenicity, safety, and immune persistence of a novel inactivated human enterovirus 71 vaccine: a phase II, Randomized, double-blind, placebo-controlled Trial.

Background: Vaccination is considered a top priority for the control of human enterovirus 71 (EV71) infection outbreaks.

Methods: On the basis of phase I trial results, we conducted a double-blind, randomized, controlled trial to evaluate the optimal dose, immunogenicity, safety and immune persistence of the vaccine. A total of 480 healthy infants were randomly assigned to receive 2 injections of 100 U of vaccine, 200 U of vaccine, 400 U of vaccine, or placebo.

The prognostic value of serum tau in patients with intracerebral hemorrhage.

Objectives: This study aimed to investigate the relationship between serum tau concentrations and 3-month clinical outcomes in patients with intracerebral hemorrhage.

Design And Methods: Serum tau concentrations of 176 patients were quantified by enzyme-linked immunosorbent assay. The end points were mortality and poor outcome (modified Rankin Scale score>2) after 3 months.

Safety and immunogenicity of a novel human Enterovirus 71 (EV71) vaccine: a randomized, placebo-controlled, double-blind, Phase I clinical trial.

Unlabelled: There is an urgent need for a novel vaccine that is effective against human Enterovirus 71 (EV71) outbreaks. A double-blind, randomized controlled study was to evaluate the safety and immunogenicity of a human EV71 vaccine in healthy adults, children and infants. The vaccine dosages were 200 U and 400 U for children and adults, and 100 U, 200 U and 400 U for infants.

Ketogenic diet protects against epileptogenesis as well as neuronal loss in amygdaloid-kindling seizures.

Ketogenic diets (KD) have shown beneficial effects in terms of anticonvulsant and anti-epileptogenic properties in several experimental models. However, few studies have investigated the consequences of KD with regards to the anti-epileptogenic and neuroprotective effects in kindling-induced seizures. Here, postnatal day 28 male Sprague-Dawley rats received one of two experimental diets for 4 weeks: (a) a 'classic' 4:1 KD; and (b) a normal regular rodent chow diet (ND).

[A study of microPET for assessing regional cerebral glucose metabolism and the expression of dopamine receptor type 2 in a rat model of Parkinson's disease].

Objective: To employ (18)F-fluoro-2-deoxyglucose ((18)F-FDG) and (3-N-[(11)C] methylspiperone)(11)C-NMSP microPET to assess the changes of regional cerebral glucose metabolism and the expression of dopamine receptor type 2 (DRD(2)) in a rat model of Parkinson's disease (PD).

Methods: A hemiparkinsonian model was established in rats by unilateral pretreatment with 6-hydroxydopamine (6-OHDA). At 2 weeks after 6-OHDA insult, (18)F-FDG and (11)C-NMSP microPET scan were performed to compare the differences of regional cerebral glucose metabolism and the expression of DRD(2) between the PD and control groups respectively.

[Effect of hyperbaric oxygen treatment on mitochondrial free radicals after transient focal cerebral ischemia in rats].

Objective: To investigate the effect of hyperbaric oxygen(HBO)therapy on mitochondrial free radicals after transient focal cerebral ischemia in rats.

Methods: The male SD rats were randomly assigned into two groups, control and HBO groups. All animals were subjected to 90 min intra-luminal middle cerebral artery occlusion (MCAO) with the regional cerebral blood flow monitored in vivo by laser Doppler flowmetry.

An insulinoma with clinical and electroencephalographic features resembling complex partial seizures.

We described a female patient with insulinoma who experienced recurrent episodes of automatism, confusion and convulsion. Furthermore, her electroencephalography (EEG) findings resembled the pattern in complex partial seizures with secondary generalization. The interictal EEG showed spikes and sharp waves, as well as focal slowing over the left temporal lobe, and the ictal EEG revealed generalized spikes and sharp waves associated with diffused slowing.

[Effect of irbesartan on focal cerebral ischemia in rats].

Aim: To investigate whether the selective AT1 receptor antagonist irbesartan exerts neuroprotective effect on focal cerebral ischemia in normotensive rats.

Methods: Cerebral ischemia was induced by middle cerebral artery occlusion (MCAO) for 90 min followed by reperfusion, with the monitoring of laser Doppler flowmetry. To avoid the interaction with peripheral AT1 receptors, irbesartan was infused intracerebroventricularly (ICV) at a dose which effectively inhibited brain- but not vascular AT1 receptors.

[Effect of hyperbaric oxygenation treatment on the apoptotic cell death pathway after transient focal cerebral ischemia].

Aim: To evaluate the effects of administration of hyperbaric oxygenation(HBO) when initiated at different time after acute transient ischemia. Apoptosis in the ischemic penumbra was further investigated to search for the possible mechanism.

Methods: The male SD rats were randomly assigned to the following groups: control, HBO therapy initiated 3 h after ischemia, HBO therapy initiated 6 h after ischemia, HBO therapy initiated 12 h after ischemia.

Significance of vascular endothelial growth factor expression and its correlation with inducible nitric oxide synthase in gastric cancer.

Aim: To investigate the clinical significance of the expression of VEGF165mRNA and the correlation with vascular endothelial growth factor (VEGF) protein and inducible nitric oxide synthase (iNO) in human gastric cancer.

Methods: We tested VEGF165mRNA expression in 31 cases of resected gastric cancer specimens and normal paired gastric mucosae by RT-PCR. Total RNA was extracted with TRIzol reagents, transcribed into cDNA with oligo (dT15) priming, inner controlled with beta-actin expression and agarose gel isolated after PCR.

[Expression of urokinase-type plasminogen activator and its receptor in plasma of patients with cerebral infarction].

Objective: To measure the urokinase-type plasminogen activator (UPA) and its receptor (UPAR) in the plasma of patients with cerebral infarction and to study the effects of UPA and UPAR on cerebral infarction.

Methods: ELISA sandwich method was used to measure the plasma levels of UPA and UPAR in 89 patients with acute cerebral infarction, subdivided into mild, moderate and severe subgroups according to the modified Edinburgh-Scandinavia stroke scale (mESSS), and 30 patients with other disease and 30 healthy persons as controls.

Results: Within 2 days after the onset of cerebral infarction the UPA and UPAR levels were (1663.

[Serum levels of soluble intercellular adhesion molecule-1 in patients with cerebral infarct].

Objective: To observe the changes of the levels of soluble intercellular adhesion molecule-1(sICAM-1) in serum of patients with cerebral infarct and to explore the effect of sICAM-1 on cerebral infarct.

Methods: The serum levels of sICAM-1 in 55 patients with cerebral infarct both in acute stage(within 2 days) and convalescence(2 weeks after attack) were detected by using ELISA. At the same time, we compare the results with those of 32 patients having other neurologic diseases(20 patients with sciatica, 12 with trigeminal neuralgia) and 30 healthy subjects.
