Since haemoplasmodium is not detected for screening in blood donor,morbidity of transfusion-associated malaria increased rapidly in China recently and became an important problem of public health.It is necessary to emphasize donor screening for malaria.Hematology analyzer with MAPSS is recommended to screen malaria.Flow cytometry and immunochromatography test(ICT)can also screen malaria effectively.For the suspicious samples with haemoplasmodium,it is necessary to be reexamined by standard microscopic examination or polymerase chain reaction(PCR).

Objective To establish a HPLC method for determination of hypoxanthine and xanthine in Syngnathus.Methods A Lichrosper C_(18) Column was used.The mobile phase was methanol-0.1%HAc.Walvelength was 254nm.Results The linear range of hypoxanthine was within 5.91～94.56?g?mL~(-1),r=0.9999,sample recovery rate was 99.22%,RSD=(1.25)%.The linear range of Xanthine was within 2.04~32.64?g?mL~(-1),r=0.9998,sample recovery rate was 98.05%,RSD=1.21%.Conclusion This method has good repeatability and flexibility.It can be used for quality control in production of Syngnathus.

Objective:To explore the relationship between cognitive deficits and oxidative stress in male patients with heroin dependence (MPHD). Methods: The cognitive function of 140 MPHD and 75 healthy controls were evaluated with Wechsler Memory Scale (WMS), Cancellation Test (CT) and Modified Wisconsin Card Sorting Test (M-WCST). The levels of serum nitric oxide (NO) and malondialdehyde (MDA) were detected in colorimetry. Results:The performances of WMS, CT and M-WCST in MPHD were significantly lower than that in healthy controls (93.7?13.8/102.9?12.3, t=-2.83; 161.6?32.8/194.4?26.5, t=-4.28; 18.8?7.8/25.0?7.5, t=-3.38, P

The RD-1 locus has been considered crucial in the pathogenesis of M.tuberculosis, the RD-1 locus is 9.5 kb and spanning open reading frames Rv3871 to Rv3879c encoding 9 different proteins separately.The RD-1 locus is missing in all bacillus Calmette-Guerin(BCG) strains, and is one of the key virulence factor in M.tuberculosis.The RD-1 locus participates in a new secreting system named ESX-1, which can facilitate the secretion of some special proteins.The two important proteins encoded by the RD-1 locus named CFP-10 and ESAT-6 can form a tight 1∶1 complex, and has been shown to be coordinately secreted and lead to a strong T cell response, which suggests that these two proteins may act as ideal target antigens in diagnosis and prevention of tuberculosis(TB).

AIM:To investigate the influence of free hemoglobin on the initiation and progression of atherosclerosis and the role of CD163 in this process.METHODS:Thirty male SD rats were randomly divided into three groups:control group(group C),atherosclerosis group(group A),atherosclerosis and hemolysis group(group P).The hemolysis and atherosclerosis animal model was established.The free hemoglobin(FHb)and MDA levels in plasma,(RAAPIs)and intima area/midmembrane area(I/M)of each group were measured.The expressions of CD163 and heme oxygenase-1(HO-1)in atherosclerosis plaques in group A and P were detected and measured by means of immunohistochemistry and Western blotting.RESULTS:Compared with group C,the FHb,MDA,CD163 and HO-1 in group A and group P increased significantly(P0.05).The FHb level in plasma and the expressions of CD163 and HO-1 in atherosclerotic plaques correlated with each other(r=0.526,r=0.498,r=0.653;P

The aim of the present study is to investigate the effects of sequoyitol (Seq) on expression of eNOS and NOX4 in aortas of type 2 diabetic rats. Type 2 diabetic rats induced by high fat and high sugar diet and low dose of streptozotocin (STZ, 35 mg x kg(-1)) and were administered Seq (12.5, 25 and 50 mg x kg(-1) x d(-1)) for 6 weeks. The fasting blood glucose (FBG) and body weight were tested. Acetylcholine (Ach) induced endothelium-dependent relaxation and sodium nitroprusside (SNP) induced endothelium-independent relaxation were measured in aortas for estimating endothelial function. Aortic morphological change was observed with HE staining. The level of serum insulin was measured by radioimmunoassay. The total antioxidative capacity (T-AOC), malondialdehyde (MDA) and NO levels in aortas were determined according to the manufacturer's instructions. In addition, the expressions of eNOS and NOX4 in aortas were measured by immunohistochemisty, real-time PCR or Western blotting. The results showed that Seq significantly decreased FBG and insulin resistance, and improved aortic endothelium-dependent vasorelaxation function. The expressions of NOX4 and MDA content were obviously decreased, while the expression of eNOS, the levels of NO and T-AOC increased significantly in aortas of diabetic rats with Seq treatment. In conclusion, Seq protects against aortic endothelial dysfunction of type 2 diabetic rats through down-regulating expression of NOX4 and up-regulating eNOS expression.
