P2 X7 receptor is a member of ATP-gated non-selective cation channels;and is one subtype family of the P2X purinergic receptor.Signaling pathways of P2X7 receptor couple with several key inflammatory molecules including IL-1β;IL-6 and COX-2;which suggests that P2 X7 receptor plays a key role in the development of dis-eases via increased inflammation;indicating its potential as a novel therapeutic target.Recent studies show that P2 X7 receptor has a relationship with renal diseases.This article reviews the effect of P2 X7 receptor on renal diseases and its mechanism.P2 X7 receptor may be a new drug target;and its selectivity antagonist may be a new therapeutic agent for the treatment of renal diseases.

Aim To investigate the protection effect of icariin on isoproterenol induced neonatal rat cardiomyocytes injury.Methods Isolation of cardiomyocytes from Sprague-Dawley rats aging 1～3 d were performed.Cardiomyocytes were grown in DMEM culture medium containing 15% fetal bovine serum.The cell density was adjusted to 1?105～5?105 cells?L-1,and the suspension was pipetted into each well of culture plates.Cells were incubated at 37 ℃ in 5% CO_2 atmosphere for 72 h.Cultured rat cardiomyocytes were divided into different groups:control,0.5 mmol?L-1 isoproterenol(model),and therapeutic groups with 0.1,1 and 10 ?mol?L-1 icariin.Cell viability was analyzed using MTT assay.The potential of mitochondrial membrane was determined by laser scanning confocal microscope.Apoptotic cells were detected by using flow cytometric analysis.Results Compared with the control group,the cell activity was lower in model group(P

AlM: To evaluate the effectiveness of Spot Vision Screener on vision screening of children without cycloplegia.METHODS:A total of 87 children (174 eyes) aged from 2~9 years old were examined with Spot Vision Screener and optometrist before cycloplegia.RESULTS: Statistical analysis demonstrated that the cylinder diopter and axis, the equivalent spherical diopter in both eyes, and the spherical diaopter in left eye had no significant change ( P>0. 05 ). However, the spherical diaopter in right eye had statistical significance. CONCLUSlON: Spot Vision Screener is a suitable instrument in vision screening of children without cycloplegia.

Uncoupling protein 4 (UCP4) is a member of the multigenic uncoupling proteins (UCPs), specific expressing in the cerebral cortex and hippocampus. UCP4 plays an important role in Parkinson's disease, multiple sclerosis, epilepsy, stroke, brain trauma and other central nervous system diseases by uncoupling, decreasing mitochondrial membrane potential,regulating Ca2+ homeostasis and oxidative stress. This article reviews UCP4 and its roles in the central nervous system diseases in order to provide certain basis for the development of UCP4targeted medication.

Objective To solve the problem that traditional electronic medical records(EMR) system could not be extended to patients' bedside because of the wired network connection restrictions.Methods Based on wireless transmission and data synchronization technologies in PDA,a mobile nursing station was developed.Results Such functions were realized as patient identity verification,implementation of doctor's orders and vital signs collection beside patients' bed.Conclusion Technical support is provided for closing EMR information chain and improving medical quality.[Chinese Medical Equipment Journal,2008,29(2):53-54]

To improve the yield of industrial fermentation, a method based on near infrared spectroscopy was presented to predict the growth of yeast.The spectral data of fermentation sample were measured by Fourier-transform near-infrared (FT-NIR) spectrometer in the process of yeast culture.Each spectrum was acquired over the range of 10000-4000 cm1.Meanwhile, the optical density (OD) of fermentation sample was determined with photoelectric turbidity method.After that, a method based on competitive adaptive reweighted sampling (CARS) was used to select characteristic wavelength variables of NIR data, and then extreme learning machine (ELM) algorithm was employed to develop the categorization model about the four growth processes of yeast.Experimental result showed that, only 30 characteristic wavelength variables of NIR data were selected by CRAS algorithms, and the prediction accuracies of training set and test set of the CARS-ELM model were 98.68% and 97.37%, respectively.The research showed that the near infrared spectrum analysis technology was feasible to predict the growth process of yeast.

Objective To compare the efficiencies of imatinib and dasatinib in patients with chronic myeloid leukemia-chronic phase (CML-CP).Methods The databases were retrieved,including Cochrane Library,OVID,Embase,PubMed,China National Knowledge Infrastructure (CNKI),WanFang database and VIP database,besides,references of articles were further to search.The quality of randomized controlled trials (RCTs) was assessed by the Cochrane collaboration' s risk tool.Meta-analysis was performed by RevMan 5.1 software.Results A total of 5 articles involved 2 031 patients with CML-CP were included.Meta-analysis showed that the rate of complete cytogenetic response (CCyR) at the 12th month in dasatinib group was higher than that in imatinib group [83.6 ％ (478/572) vs 70.6 ％ (406/575),OR =2.11,95 ％ CI 1.59-2.80,P＜ 0.05],and the rate of major molecular response (MMR) at the 12th month in dasatinib group was higher than that in imatinib group [49.3 ％ (296/600) vs 30.6 ％ (185/605),OR =2.22,95 ％ CI 1.75-2.82,P ＜ 0.05].Conclusion Dasatinib can improve CCyR and MMR rate at the 12th month in CML-CP patients.

AIM: To investigate the effect of lipopolysaccharide (LPS) priming on macrophage(M?). METHODS: Macrophage cell line RAW264.7 were pretreated with or without LPS for 1 h, then challenged with PMA, or LPS, muramyl dipeptide(MDP), Zymosan, formyl-methionyl-leucyl-phenylalanine(FMLP) for 1 h . O  2 production in supernatants and intracellular free calcium([Ca 2+ ]i ) were measured, and changes in [Ca 2+ ]i and LPS induced O  2 production were compared. RESULTS: LPS pretreatment significantly increased O  2 production in RAW264.7 cells challenged with the stimuli, and in a certain extent, both O  2 production and increase of resting intracellular [Ca 2+ ]i were dose- and time-dependent on LPS pretreatment.Furthermore,the peak [Ca 2+ ]i was significantly higher in LPS pretreated groups than that of LPS unpretreated groups when challenged with PMA. Pretreatment with Ca 2+ inophore A23187 mimicked the LPS priming effects on O  2 production, but pretreatment with Ca 2+ chelator BAPTA and EGTA blocked this priming effect. CONCLUSION: LPS induced M? priming effect on O  2 production is dependent on elevation of resting intracellular [Ca 2+ ]i .
