Endothelial monocyte-activating polypeptide-Ⅱ (EMAP-Ⅱ ) is a novel proinflammatory cytokine with proinflammatory,proapoptotic and antiangiogenic properties.It is associated with many tumorassociated proteins,such as tumor necrosis factor,vascular endothelial growth factor,hypoxia inducible factor-1α,arginyl-tRNA synthetase,and insulin-like growth factor- Ⅰ.EMAP-Ⅱ has anti-tumor properties and has a good prospect in cancer prevention and treatment.

Objective:To investigate the different function of dendritic cells between patients with lupus nephritis and healthy control,and discuss the pathogenesis of the disease.Methods: Choose 50 healthy controls,50 patients with lupus nephritis,and isolation of blood dendritic cells.Then samples were induced with GM-CSF and IL-4,and cells were collected on day 7.DC maturity was evaluated using the following methods:fluorescence-activated cell sorting analysis for cell surface markers;enzyme-linked immunosorbent assay for cytokine production;cell proliferation assay for induction of T cell proliferation.Results: Compared with the control group,lupus nephritis group had increased MHC Ⅱ,CD86,CD80,and CD40 expression(P<0.05);displayed the increased IL-12 and TNF-αlevels(P<0.05);displayed a increased ability to drive lymphocyte cells proliferation (P<0.05).Conclusion:Compared with the control group ,dendritic cells in lupus nephritis group displayed the mature condition ,which indicates that dendritic cells play the important role in the pathogenesis of lupus nephritis.

Objective To evaluate the effectiveness of periodontal mechanical therapy on periodontal health and interleukin-6 (IL-6) levels in gingival crevicular fluid (GCF) in type 2 diabetic patients with chronic periodontitis. Methods GCF samples were obtained with filter papers in first molar sites from 37 type 2 diabetic patients with chronic periodontitis. The randomized controlled and blinded clinical trial with a duration of six months was designed to compare effects between three groups of professional mechanical tooth cleaning (PMTC), i.e. coronal scaling (group Ⅱ) with periodontal initial therapy (group Ⅰ) and without clinical therapy (control group). The clinical periodontal index such as probing depth (PD), attachment loss (AL), modified bleeding index (mBI) and bacteria plaque index (PLI) were obtained with a Williams type periodontal probe. Laboratory examination including GCF volume, concentrations and total amounts of IL-6 in GCF were detected with ELISA method. Results Significantly decreasing trends of PD, AL, mBI, GCF volume and total amounts of IL-6 were observed in group Ⅰin all test period. The group Ⅱ had a significant reduction of PD at the third month as compared with baseline (⊿=0.36 mm, P＜0.05), and the other figures showed descending trends but didn′t present statistical significances. At the end of study, the group Ⅰand Ⅱ had significant reductions of GCF volume compared with increases of control group (0.96 μ1＞0.03 μ1mm＞-0.20 μ1, P＜0.05). Conclusions The sequential periodontal supra- and sub- gingival scaling has definitive effects on periodontal health improvement and on reducing the IL-6 level in GCF in type 2 diabetic patients.

Epidemics of hand, foot and mouth disease (HFMD) have mainly been caused by Coxsackievirus A16 (CVA16) and Enterovirus A 71 (EV-A71), which circulated alternatively or together in the affected area. CVA16 has caused numerous outbreaks and epidemics in multiple countries and geographical regions, and has become an important public health problem. Based on an analysis of the complete VP1 coding region, all CVA16 strains can be divided into genotypes A, B1, and B2. Furthermore, genotype B1 can be divided into subgenotypes B1a, B1b, and B1c. After 2000, no reports of genotype B2 virus strains have been reported. All of the CVA16 strains reported in mainland China have belonged to subgenotypes B1a and B1b. Most CVA16-associated infections cause only mild symptoms; however, some CVA16 infections can lead to severe complications and even death. Vaccination is considered to be the most effective method to control the transmission and infection rate of this virus. A number of research groups are studying various vaccine types, including inactivated vaccines, genetic engineering vaccines, and DNA vaccines, amongst others. In this review, an overview is provided of the research advances in molecular epidemiology and vaccines of CVA16.

Objective To investigate the effects of different doses of fentanyl on pain-activated brain areas as demonstrated by functional magnetic resonance imaging (fMRI) at 3.0 T.Methods Twenty healthy right-handed male volunteers aged 20-40 yr were randomly divided into 2 groups ( n =10 each); group F1 (fentanyl 1.0 μg/kg) and group F2 (fentanyl 1.5 μg/kg).Mechanical stimulation with von Frey filaments (vFFs,300 g) was delivered to left sole.The intensity of pain was assessed by VAS scores.fMRI was performed before and after fentanyl administration and the changes in the brain areas activated by pain were recorded.Results In group F1 ipsilateral (left) cingulate gyrus was activated after a bolus of fentanyl 1.0 μg/kg under stimulation with vFFs 300 g,while in group F2 bilateral cingulate gyrus and contralateral (right) insula were activated under vFFs stimulation after fentanyl 1.5 μg/kg.Conclusion Cingulate gyrus and insula may be the target brain areas of fentanyl analgesia.

BACKGROUND:Intracerebral administration of selective drugsviathe carotid artery is currently one of the effective methods to enhance the drug concentration in the brain and reduce the influence of drugs on other system functions. OBJECTIVE:To establish the muscle-relaxation rabbit models by infusing propofol continuously in the internal carotid artery and analyze the variations of propofol concentration. METHODS: The muscle-relaxation rabbit models were established by continuously infusing propofol at a constant speedviacatheterization in the internal carotid artery. The pharmacokinetic characteristics could be analyzed by the methods of obtaining arterial and venous blood on both sides of neck and samples of brain tissue on both sides in different points, detecting drug concentration using high pressure liquid assay, and then mathematicaly conversing the resulting data for fitting processing and statistical regression. RESULTS AND CONCLUSION:The method of determining the concentration of propofol using high pressure liquid assay is feasible, stable and reliable. Through investigating the concentration of propofol infused via the carotid artery at different time points, we discovered that the growth rate distribution of propofol concentration and data distribution are in log-normal distribution profile which belong to non-exponential kinetics model,i.e., modified log-normal distribution model,??)(ln x μ 2 1 fx ()=e 2σ2 , whereσ is the range of drug concentration growth indicating stability xk 2πσ of concentration changes, which is an integrated variable related to various factors, such as brain tissue uptake of drugs and brain circulation. The pharmacokinetic model of continuously infusing propofol in the internal carotid artery belongs to log-normal distribution function, i.e., a non-exponential function kinetics model. The brain concentration variations on both sides changing over time folow log-normal distribution function law.

Objective To investigate the possible effects on radiosensitivity in human umbilical vein endothelial cells after transfection of pcDNA3.1+Ape1 plasmid. Methods The expressing vector pcDNA3.1+ Ape1, the control vector pcDNA3.1+or non-transfection cells was irradiated by 2, 4, 6, and 8 Gy photon beam at 48 h post-transfection. The value of initial and residual Oliver tail moment (OTM) under the alkaline single cell gelelectrophoresis assay and the colony forming test were utilized as the markers for the evaluaton of cells intrinsic radiosensitivity. The effect on radiosensitivity in human umbilical vein endothelial cells after transfection of the expressing vector pcDNA3.1+Ape1 was analyzed according to the radio-dose, compared to the empty vecor control and non-transfection cells. Results The initial and residual OTM value of endothelial cells transfected by 3 μg pcDNA3.1+Ape1 plasmid was lower significantly than ones of endothelial cells untransfected at 2 Gy irradiation (P<0.01), but was no significant difference at 8 Gy (P>0.05), and SF2 was higher remarkably in transfected cells than one in untransfected cells (P<0.05), but SF4, SF6 and SF8 were no significant differences (all of P>0.05). Conclusions The transfection of pcDNA3.1+Ape1 plasmid could enhance radioresistance of endothelial cells to the low-dose irradiation.
