OBJECTIVE: To investigate the effect of enzymatically modified low density lipoprotein(E-LDL) on differation and maturation of human dendritic cells(DC) in peripheral blood and the effect of diltiazem on it.METHODS: Human monocytes were isolated by using gradient centrifugation method and cultured in DC Cellgro medium containing rhGM-CSF and rhIL-4 for 5 days,then DC was then obtained.DC were treated with E-LDL or E-LDL plus diltiazem for 48 hours,the morphological changes were observed under the microscope,and the FACS was used to investigate the expression of DC(CD1a,CD80,CD86 and HLA-DR).PBS group was set up for comparison.RESULTS: The morphological changes were nor observed.The expressions of CD1a,CD80,CD86 and HLA-DR in each groups were significant different(P

Objective To investigate the relationship between microalbuminuria (MAU) and the risk factor for acute ischemic stroke,the severity of the disease and outcomes.Methods A total of 156 consecutive patients with acute ischemic stroke were enrolled prospectively.They were randomly divided into either an MAU positive group (≥ 30 mg/g) or an MAU negative group (＜ 30 mg/g) according to urinary albumin/creatinine ratio (UACR).They were also randomly divided into either a good outcome group (0-2) or a poor outcome group (＞2) according to the modified Rankin scale (mRS) scores.The various demographic and clinical data were compared,and the poor outcome of acute ischemic stroke and the independent factors of positive MAU were analyzes.Results A total of 156 patients with acute ischemic stroke were enrolled,including 84 males and 72 female; aged 53 to 78 years (mean 65.4 ± 6.2); the time from onset to admission was 1.5 to 28 h; 94 patients had good outcomes,62 had poor outcomes,and no one died; MAU was positive in 76 patients and MAU was negative in 80 ones.Multivariate logistic regression analysis showed that advanced age (odds ratio [OR] 1.992,95％ confidence interval [CI] 1.108-2.374; P =0.015),complicated with diabetes (OR 2.497,95％ CI 1.177-5.298; P =0.017) and atrial fibrilhtion (OR 2.338,95％ CI 1.062-5.148; P =0.035),high serum homocysteine (Hcy) level (OR 2.541,95％ CI 1.073-6.02; P =0.047) and UACR (OR 2.130,95％ CI 1.396-3.017; P =0.001),MAU positive (OR 3.291,95％ CI 1.681-6.444; P =0.001),high baseline National Institutes of Health Stroke Scale (NIHSS) score (OR 9.196,95％ CI 2.828-19.815; P＜ 0.001) were the independent risk factors for poor outcomes in patients with acute ischemic stroke.There were significant differences in the proportion of the patients complicated with diabetes (P =0.038) and fasting blood glucose level (P =0.025),serum Hey level (P =0.022),and carotid intima-media thickness (IMT) (P =0.019) between the MAU positive group and the MAU negative group.The proportion of anterior circulation infarction was lower (P =0.033),the rates of the baseline NIHSS score (P =0.003) and poor outcome were higher in the MAU positive group (P ＜ 0.001).Multivariate logistic regression analysis showed that increased diabetes (OR 2.237,95％ CI 1.036-4.829; P =0.040) and fasting blood glucose (OR 1.223,95％ CI 1.145-1.673; P =0.027),the increased Hey level (OR 2.542,95％ CI 1.047-6.612; P=0.025),carotid artery IMT (OR 1.295,95％ CI 1.106-1.362; P =0.023) and baseline NIHSS score (OR1.206,95％ CI 1.044-1.219; P =0.023) were correlated independently with the positive MAU in patients with acute ischemic stroke.Conclusions Positive MAU is one of the independent risk factors for poor outcomes of acute ischemic stroke,it is closely associated with some risk factors for acute ischemic stroke,and it has a significant impact on the severity of acute ischemic stroke and outcomes.

Objective To explore the correlation of pulmonary heart disease (PHD) with erythrocyte immunity function and serum erythropoietin(EPO)level. Methods Forty-eight patients with PHD were selected as PHD group, while forty people were chosen as control group. The erythrocyte C3b receptor (E-C3bRR), erythrocyte immunity complex (RBC-ICR) and serum EPO content were detected by yeast rosette method and enzyme-linked immunosorbent assay (ELISA),and blood gas indexes were examined by blood gas analyser.Results The E-C3bRR and serum EPO content were lower, while the RBC-ICR was higher in PHD group than in control group(both P< 0. 01). Compared with control group, PCOz and HCO3-levels were higher, but blood oxygen saturation(SaO2) level was lower in the PHD group than in control group(both P<0. 01). There were no differences in pH value and PO2between two groups(both P>0. 05). The E-C3bRR was positively related to serum EPO content (r=0. 623, P<0.01), and HCO3-was positively related to pH value and PCO2(r=0. 219 ,P<0. 05;r=0. 585,P<0. 01) ,whereas PCO2was negatively related to pH value(r=-0. 529,P<0.01),and PO2was positively related to SaO2(r=0. 682,P<0.01)in PHD group. Conclusions There is a correlation between E-C3bRR and serum EPO content in PHD patients.

Aim To isolate HIV-1 from the blood specimen of HIV-infected persons, and study on the features of the isolates. Methods PBMCs from 10 heparinized blood specimens of HIV-1 infected persons were collected to isolate the virus with PBMC cocultivation method. Neuramindase was added to the culture medium to raise the HIV isolation rate. The supernatant of cocultures were detected by p24 antigen capture assay and also IFA test was used to identify the isolates. Cell tropism of the HIV-1 isolates was tested byuse of H9 and MT4 cell lines, respectively. Results HIV-1 was isolated from9 of the 10 specimens, the isolation rate could reached 90%. The 9 isolates were used to infect MT4 cells, respectively, and all of them could cause cell syncytias.8 of the isolates showed only a transient infection in MT4 cells, but the isolate FJ113 could infect MT4 successively, OD values kept no changes even it passed 15 generations, therefore, it is consider as a rapid/high replicating virus. Conclusions Addition of neuramindase into T cell culture medium may useful to raise HIV isolation rate. Most of HIV-1 isolates in Fujian are M tropic.
