BACKGROUND: Edaravone can alleviate brain injury and improve neurological functions and symptoms. This study aimed to investigate the effect of edaravone on the p38Mitogen-activated protein kinases/Caspase-3 (p38MAPK /Caspase-3) pathway after diffuse brain injury (DBI) in rats. METHODS: DBI models were established according to the description of Marmarou's method. A total of 250 rats were divided (random number) into four groups: control group (CG, n=45), model group (MG, n=77), low-dose edaravone group (n=67, dosage 5 mg/kg) and high-dose edaravone group (n=61, dosage 10 mg/kg). After 1, 6, 24, 48, and 72 hours after injury, brain tissues were collected. The changes of neuron morphous in the hippocampal region were observed through Nissl staining. The expression levels of phosphorylated p38MAPK and caspase-3 were detected by immunohistochemistry and Western blotting respectively. Learning and memory function were tested with Morris water maze from the 3rd to 7th day after injury. RESULTS: Some neurons had histopathologic changes of necrosis and apoptosis in the model group compared with the control group. The phosphorylated p38MAPK expressions increased at 1, 6, 4, and 48 hours (P<0.05), but no significant difference was observed at 72 hours (0.54±0.19 vs. 0.40±0.14, P>0.05). Caspase-3 expressions increased at 6, 24, 48, and 72 hours respectively (P<0.05), but there was no significant difference at 1 hour (0.59±0.29 vs. 0.40±0.17, P>0.05). From the 3rd to 6th day during the Morris water maze test, the latency to find the platform was significantly prolonged (P<0.05) and times of rats crossing the platform was decreased on the 7th day (2.28±1.18 vs. 8.20±1.52, P<0.05). The phosphorylated p38MAPK expressions decreased at 6, 24 and 48 hours respectively in the low dose edaravone group compared with the model group (P<0.05), whereas no significant difference was seen at 1 hour (1.66±0.80 vs. 1.85±0.86, P>0.05). Caspase-3 expression decreased at 6, 24, 48, and 72 hours (P<0.05). The latency to find the platform was significantly shortened (P<0.05), and times of rats crossing the platform increased (4.17±1.15 vs. 2.28±1.18, P<0.05). The above mentioned parameters changed more significantly in the high-dose edaravone group than in the low-dose edaravone group. CONCLUSION: Edaravone can alleviate brain tissue damage after DBI, inhibit p38MAP signal activation after early injury, reduce the expression of caspase-3, and promote the recovery of neurological function in the late period.

Objective To explore the association between ambient average temperature and hospital emergency room visits for cardiovascular diseases(International Classification of Diseases,Tenth Vision ICD-10:I00-I99) in Beijing,China.Methods Data was collected on daily hospital emergency room visits for cardiovascular diseases from Peking University Third Hospital,including meteorological data(daily average temperature,relative humidity,wind speed,and atmospheric pressure) from the China Meteorological Data Sharing Service System,and on air pollution from the Beijing Municipal Environmental Monitoring Center.Time-stratified case-crossover design was used to analyze data on 4 seasolls.Results After adjusting data on air pollution,1 degree(℃) increase of ambient average temperature would associate with the emergency room visits of odds ratio(Ors)as 1.282(95%CI:1.250-1.315).1.027(95%CI:1.001-1.055),0.661(95%CI:0.637-0.687),and 0.960 (95%CI:0.937-0.984) in spring,summer,autumn,and winter respectively.After controlling the influence of relative humidity,wind speed,and atmospheric pressure,1℃ increase in the ambient average temperature would be associated with the emergency room visits on Ors value as 1.423 (95%CI:1.377-1.471).1.082(95%CI:1.041-1.124),0.633(95%CI:0.607-0.660)and 0.971(95%CI:0.944-1.000) in spring,summer,auttmm,and winter respectively.Conclusion These data on outcomes suggested that the elevated level of ambient temperature would increase the hospital emergeney room visits for cardiovascular diseases in spring and summer while the elevated level of ambient temperature would decrease the hospital emergency room visits for the cardiovascular diseases in autumn and winter,suggesting that patients with cardiovascular diseases should pay attention to the climate change.

OBJECTIVETo analyze the genetic polymorphism, distribution of haplotypes, common and well-documented (CWD) and rare alleles of high-resolution HLA-A, B and DRB1 alleles by analysis from hematopoietic stem cell (HSC) donors in Jiangsu Han Chinese.
METHODSPCR-sequence-based typing and PCR-sequence specific oligonucleotide probes methods were applied for HLA-A, B and DRB1 high-resolution genotyping of 3238 unrelated healthy donors of hematopoietic stem cells in Jiangsu branch of Chinese National Marrow Donor Program registry.
RESULTS46 alleles of HLA-A,85 HLA-B and 51 HLA-DRB1 locus were found. The frequencies of the most common alleles were A * 11:01 (16.52%), B * 13:02 (11.60%) and DRB1 *07:01 (15.78%). That of the most common haplotype was A * 30: 01-B * 13: 02-DRB1 * 07: 01 (8.87%). 40 alleles of HLA-A,77 alleles of HLA-B, and 47 HLA-DRB1 alleles of HLA-DRB1 were CWD, which account for 99. 8% of total number of samples, and a few rare alleles not reported in Chinese population were found.
CONCLUSIONThe results of high-resolution, CWD and rare alleles showed the characteristics of HLA distribution in Jiangsu Han population, which may be useful for finding HLA matched unrelated donors, as well as for HLA correlation with population genetics and disease association studies.

AIM To establish an HPLC method for determining the contents of three constituents in Polygoni multiflori Radix Praeparata in plasma of atherosclerosis rats.METHODS After the rats were intragastrically administrated with Polygoni multiflori Radix Praeparata CMC-Na solution,the plasma was collected.The HPLC analysis was carried out on a 30 ℃ thermostatic Hypersil C1s column (250 mm ×4.6 mm,5 μm),with the mobile phase comprising of acetonitrile-0.03% phosphoric acid flowing at 0.9 mL/min in a gradient elution manner,and the detection wavelength was set at 280 nm.DAS2.0 software was applied to drawing concentration-time curves and calculating pharmacokinetic parameters.RESULTS Stilbene glucoside,emodin and physcion showed good linear relationships within the ranges of 61.25-6 125 μg/L (r =0.999 8),12.6-3 150 μg/L (r =0.999 3) and 24.1-6 030 μg/L (r =0.999 5),respectively.The method recoveries were 99.5%-105.8% with the RSDs of 1.3%-3.3%,while the extraction recoveries were 87.2%-96.3% with the RSDs of 3.2%-5.9%.The pharmacokinetic behaviors of three constituents all accorded with two-compartment model,but their contents in plasma were much lower than those in medicinal material.CONCLUSION The bioavailabilities of stilbene glucoside,emodin and physcion are relatively low in plasma of atherosclerosis rats,which may be related to constituents' intestinal absorption after intragastric administration with Polygoni multiflori Radix Praeparata.

OBJECTIVETo study the linkage between -148C/T polymorphism of beta-fibrinogen gene and plasma fibrinogen levels in patients with acute cerebral infarction.
METHODSOne hundred and fifty-one patients with cerebral infarction and 101 healthy individuals were enrolled in this trial. The beta-fibrinogen gene -148C/T polymorphism was analyzed by PCR-restriction fragment length polymorphism, and plasma fibrinogen levels were obtained from prothrombin time assay.
RESULTSPlasma fibrinogen levels of patients were significantly higher than those of controls (P<0.01). In both groups, T allele carriers had higher plasma fibrinogen levels than other those did (P<0.01); and the fibrinogen level difference was still significant if both groups was based on their sex (P<0.05). Divided by age, each group of the study cases has significant difference between two genotypes (P<0.05). T -148 allele frequency of the middle age case in study group was higher than that in control group (P<0.05).
CONCLUSIONHigh plasma fibrinogen level is a risk factor to cerebral infarction. Plasma fibrinogen level is affected by -148C/T polymorphism of beta-fibrinogen gene. With or without other risk factors and environmental factors affecting, T allele increases plasma fibrinogen level and may be a heritable risk factor to cerebral infarction.
