Objective To investigate the changes of vascular endothelial growth factor (VEGF),transforming growth factor-?1 (TGF-?1) and platelet derived growth factor (PDGF) in plasma and apheresis platelets with or without activation by shaking. Methods A total of 10 units of double therapeutic dose platelets were collected and each unit was divided into 3 groups to take samples of plasma (3ml/person,as control group),fresh apheresis platelets (5ml/person,as experimental group1) and activated apheresis platelets (platelets stored by shaking at 22 ℃ for 5 days,5ml/person,as experimental group2). The levels of VEGF,TGF-?1 and PDGF in the samples of the 3 groups were measured by ELISA. The expression of CD62p in 2 apheresis experimental groups was measured by flow cytometry. The differences between the two groups were compared. Results The levels of VEGF,TGF-?1 and PDGF,which were (410.95?95.07) pg/ml,(91.15?19.50) ng/ml and (12.60?2.06) ng/ml,respectively,in group 1 were markedly higher than those in the plasma control group,which were 149.09?28.11,37.38?10.73 and 3.28?0.79,respectively (P

Objective To study the bacteriological effect of different dosages of gamma irradiation on Escherichia Coli (E. Coli) in red blood cells (RBC) products,and assess the appropriate dose of gamma irradiation. Methods Prepare RBC samples inoculated with(102-106)/ml of E. Coli. The contaminated RBCs were irradiated by 0 (as control),15,20,25,30 and 35Gy of gamma irradiation. E. Coli in the RBCs were tested on days 0,7, and 14 after irradiation. Results The quantities of E. Coli changed after irradiation. The RBCs inoculated with less than 103cfu/ml of E. Coli were completely sterilized by 25 Gy irradiation. Conclusion 25 Gy gamma irradiation can eradicate less than 103cfu/ml of E. Coli in the RBC products.

OBJECTIVE:To investigate the improvement effect of Prostatitis capsule on chronic non-bacterial prostatitis(CNP) model rats. METHODS:60 rats were randomly divided into sham operation group (distilled water),model group (distilled wa-ter),Pule'an tablet group(positive control,2 g/kg)and Prostatitis capsule high-dose,medium-dose,low-dose groups(16,8,4 g/kg). Except for sham operation group,other 5 groups were injected Xiaozhiling injection 0.2 mL to reduce CNP model. After 7 d of modeling,they received related medicines,ig,once a day,for 45 d. After 24 h of last administration,prostate lesions were ob-served by eyes and wet quality was weighed. White blood cell(WBC)count and lecithin body(SPL)count were conducted under microscope,and prostate tissue slices were pathologically observed. RESULTS:Compared with sham operation group,prostate showed gray nodules,adhesion in glands and surrounding tissue;wet quality of prostate and WBC,SPL count in prostate tissue were significantly increased(P<0.01);under microscope,there were significant congestion,edema and a variety of inflammatory cell infiltration in prostate interstitial. Compared with model group,gray nodules in prostate in Pule'an tablet group and Prostatitis capsule group were reduced,as well as adhesion degree in prostate and surrounding tissue;wet quality of prostate and WBC,SPL count in prostate tissue were significantly decreased(P<0.01);pathological changes had improved to varying degrees under micro-scope,especially the changes in Prostatitis capsule high-dose group,and prostate tissue only showed mild congestion,edema and little inflammatory cell infiltration. CONCLUSIONS:Prostatitis capsule has a certain improvement effect on CNP model rats.

69 crabs were collected from Daxing, Gekui and Niukong townships of Lvchun county, Yunnan Province in 2006 and excysted metacercariae were only obtained from crabs of Niukong. The infection rate was 27.6% (8/29) with an average metacercaria number of 2.25 each crab. No encysted metacercariae were found. The excysted metacercariae were morphologically identified as Paragonimus proliferus.

Objective To study the effect of anti-epileptic,nootropic drugs on the expression of NCAM and ERK2 in the hippocampus changes on the epileptic rats with cognitive dysfunction.Methods A total of 120Wistar rats were used.20 controls and 100 in which epilepticus with cognitive dysfunction were randomly assigned to 5 groups (n =20/group) that received daily treatments for 30 days with either (1) saline (epilepsy),(2) carbamazine (traditional anti-epileptic),(3) oxcarbazine (new anti-epileptic),(4) aniracetam (brain protective),or (5) donepezil (nootopic).Spatial learning and memory were assessed with a Morris Water Maze (MWM).Hippocampus tissue was assessed for NCAM1 and ERK-2 mRNAs by RT-PCR and proteins by immunochemistry.Results The mean escape latency of the place navigation test:EP group ((67.14 ± 7.37)s)was all higher than NS group (35.78 ± 4.84 s)and there was statistical significance (P ＜ 0.01),carbamazepine group ((81.23 ± 9.46)s) ＞ EP group((67.14 ±7.37)s) ＞ donepezi group((53.75 ±6.74) s) (P＜0.01).Immunohistochemical and RT-PCR result:carbamazepine ＜ oxcarbazepine ＜ epilepsy ＜ aniracetam ＜ donepezi group.Compared with control group,donepezil group ＞ control group (P ＜ 0.01),aniracetam group ＞ control group (P ＜ 0.05).Conclusion ERK-2 expression is decreased and NCAM 1 expression is increased in the hippocampus in the epileptic rats.Thus,both are involved in cognitive dysfunction.Carbamazepine aggravates cognitive dysfunction,whereas donepezil improves cognitive dysfunction associated with epilepsy.

INTRODUCTIONThe present study aimed to investigate the possible associations between serum levels of visfatin, an adipokine, and atherosclerosis in patients with ischaemic cerebrovascular disease.

METHODSA total of 95 participants were recruited for this study. Group A comprised 35 individuals with no history of cerebrovascular disease (control group) and Group B comprised 60 patients with ischaemic cerebrovascular disease. Group B was further categorised into two subgroups based on the ultrasonographic findings of the common carotid artery intima‑media thickness (CCA‑IMT) - Group B1 consisted of 21 patients with no atherosclerosis (i.e. CCA‑IMT ≤ 0.9 mm) and Group B2 consisted of 39 patients with atherosclerosis (i.e. CCA‑IMT > 0.9 mm). The body mass index, fasting blood total cholesterol, triglycerides, high‑density lipoprotein cholesterol, low‑density lipoprotein cholesterol and glucose levels of each patient were measured. Serum visfatin levels were determined using enzyme‑linked immunosorbent assays. Visfatin levels were compared between groups, and stepwise logistic regression analysis was used to identify risk factors for atherosclerosis, including visfatin levels.

RESULTSThe mean serum visfatin level of the patients in Group B was higher than that in Group A (75.5 ± 77.80 ng/mL vs. 8.6 ± 4.69 ng/mL; p < 0.05) and the level was higher in patients from Group B2 than those from Group B1 (89.0 ± 80.68 ng/mL vs. 50.4 ± 72.44 ng/mL; p < 0.05). Multivariate regression analysis showed that CCA‑IMT values were not significantly associated with visfatin levels. However, logistic regression analysis showed that serum visfatin was an independent risk factor for atherosclerosis (odds ratio 37.80; p = 0.004).

CONCLUSIONSerum visfatin may be an independent risk factor for cerebral infarction, as high serum visfatin levels are positively associated with the underlying pathogenic mechanisms of ischaemic cerebrovascular disease.
