A method for measurement of neutrophil function and opsonic activity by chemiluminescence (CL) was reported in this paper.The factors influencing the emission of CL were discussed. The experimental results suggested that CL depends on the concentration of luminol, the dilution of serum opsonin, the number of neutrophils and the environmental temperature. The optimum conditions defined in present study were: the concentration of luminol was 1?105M, the number of neutrophils 2?106/mml, the reactive temperature 37℃. According to the relationship between CL emission and the bactericidal activity of phagocytizing neutrophils, the measurement of CL may be used as a rapid, simple and usefull tool to determine the funetion of humoral-phagocyte axis.

Objective To investigate clinical significance and related factors of fluid-attenuated inversion recov?ery vascular hyperintensities (FVH) in transient ischemic attack (TIA) of carotid system. Method Data including general information and TIA risk factors was continuously collected from 142 patients with carotid system TIA from the depart?ment of neurology of Sheng jing Hospital affiliated China Medical University from January 2012 to February 2014.All pa?tients completed brain MRI including FLAIR and diffusion-weighted imaging (DWI)and MRA examinations within 72 hours after TIA. All patients were followed up for one month. Risk factors and FVH situations were analyzed based on clinical manifestations and DWI results. Result There were 87 male cases (61.27%)and FVH positive 57 cases (40.14%) among 142 cases with carotid system TIA (mean age 63.2±11.5). Logistic regression analysis revealed that the large intra?cranial carotid artery stenosis≥50%(OR=2.44,95%CI:1.09~5.49, P=0.03) and prior history of ischemic stroke (OR=3.88,95%CI:1.04~14.5, P=0.04) were independently associated with positive FVH. At one month followed-up, 40 cas?es (28.17%) of 142 patients progressed to acute cerebral infarction. Vulnerable plaque number in the contralateral carot?id artery (P=0.018), contralateral intracranial large vessel stenosis in MRA≥50%(P=0.007) and contralateral FVH oc?currence rate (P=0.001) were significantly higher in cerebral infarction group than in non-cerebral infarction group. Con?clusion FVH is common in carotid TIA patients, which is associated with intracranial carotid artery stenosis ischemic and previous history of ischemic stroke. Vulnerable plaque number of contralateral carotid artery, contralateral intracranial large vessel stenosis≥50%and the rate of occurrence of contralateral FVH may be associated with short-term progress leading TIA to acute infarction.

Objective To investigate the effects of eritoran on the expressions of the inflammatory cytokines interleukin-1β (IL-1β),tumor necrosis factor-α (TNF-α) and interferon-[ (IFN-β) mRNA in the basilar artery after subarachnoid hemorrhage (SAH) in rabbits.Methods Atotal of 36 healthy adult male New Zealand white rabbits were randomly allocated into three groups:SAH (n =12),normal saline (n =12) and eritoran (n =12) groups.A SAH model was induced by injection of autologous arterial blood into cisterna magnatwice.An equal amount of cerebrospinal fluid was displaced with the saline in the normal saline group.An equal amount of autologous non-heparinized arterial blood was injected immediate after the replacementof cerebrospinal fluid in the SAH group.Eritoran 1.5 mg/kg was injected intravenously immediately after the blood injection via the cisterna magna each time in the eritoran group.The food intake and neurological deficit were assessed.The expressions of IL-1β,TNF-α and IFN-β mRNA in the basilar artery were detected by real-time fluorescence quantitative polymerase chain reaction.Results The food intake scores (1.20 ± 0.41 vs.2.20 ±0.61; t =53.073,P =0.002),the neurological deficit scores (1.46 ± 0.32 vs.2.6 ± 0.08; t =306.431,P =0.001),the expressions of IL-1β (1.22 ±0.48 vs.2.38 ±0.06,P =0.000),TNF-α (1.39 ±0.07 vs.3.32 ±0.21,P =0.000) and IFN-β (1.51 ±0.08 vs.2.18 ±0.05,P =0.000) in Eritoran group were all significantly lower than those in the SAH group.Conclusions Eritoran may downregnlate the expressions of inflammatory cytokines IL-1β,TNF-α and IFN-β mRNA in the basilar artery after SAH in rabbits,increasing food intake,and improving neurological deficits.
