Objective To investigate effects of early administration of high-dose rosuvastatin(40 mg) on coronary microvascular function and short-term outcome in patients treated with primary percutaneous coronary intervention (PCI) for acute myocardial infarction(AMI). Methods Ninety-four consequent AMI patients treated with primary PCI were divided into rosuvastatin group (50 patients) and control group (44 group). The infarct-related artery flow of epicardium was classified in compliance with the TIMI criteria. Myocardial and microvascular perfusion was assessed using the TMPG. The incidence of the MACE and the cytotoxicity and hepatotoxicity of rosuvastatin was respectively recorded in 30 d follow-up period. Results Either patients in the rosuvastatin group or in the control group showed better TMPG immediately after PCI (P<0.05), compared with that before treatment. However, the post-PCI TMPG of the rosuvastatin group was obviously much better than that of control group (P<0.05). Compared with that in control group, the 30-day composite MACE rate was lower in rosuvastatin group and in the TMPG 3 patients of rosuvastatin group:12.0%(6/50) vs. 34.1%(15/44), P<0.05;11.1%(3/27) vs. 42.9%(6/14). There was no cytotoxicity and hepatotoxicity in two groups. Conclusions Early administration of high-dose rosuvastatin (40 mg) can improve coronary microvascular function and short-term outcome in patients treated with primary PCI for AMI, and it is efficient and safety.

BACKGROUND:Enriching material for bone marrow stem cells is a current research hotspot. Preparation and screening of a new type of bone marrow stem cells-enriched material is crucial for the development of tissue engineering and clinical applications. OBJECTIVE:To observe the surface character and effect of a new type of bone marrow stem cells-enriched material on enriching bone marrow stem cells of decalcified bone matrix decorated with poly-L-lysine by selective cellretention technology. METHODS:Decalcified bone matrix was decorated with poly-L-lysine as the scaffold material. Bone marrow mesenchymal stem cells were col ected by using selective cellretention technology. Control group was decalcified bone matrix and experimental groups were Decalcified bone matrix decorated with poly-L-lysine at different concentrations (0.01%, 0.05%, 0.1%, 0.5%, 1%) with freeze-drying method. Material components were analyzed by Raman spectrum and infrared spectrum. Pore size, porosity, surface and cross section were observed under three-dimension video microscope and scanning electron microscope. The number of bone marrow nucleated cells, fibroblast colony-forming units and platelets were counted pre-and post-enrichment. RESULTS AND CONCLUSION:Decalcified bone matrices were covered with wel-distributed and dense poly-L-lysine. The poly-L-lysine/decalcified bone matrix had a high porosity with much more internal y connected pores. After enrichment with enriched material prepared by 0.1%poly-L-lysine, the number of bone marrow nucleated cells, fibroblast colony-forming units and platelets were increased (3.18±0.31), (5.25±1.40) and (3.88±0.68) times, respectively;the binding efficiency were (53±12)%, (73±13)%and (34±10)%, respectively;the selective rate of fibroblast colony-forming units was 1.41±0.34. The new constructed poly-L-lysine/decalcified bone matrix has good three-dimension space with high selective retention. It is an effective enriching material for bone marrow mesenchymal stem cells.

Objective:To analyze risk factors that were associated with loss of correction curvature after short-segment restoration and fixation in cases who had single-segment thoracolumbar fracture.Methods:87 Cases who had experienced single-segment thoracolumbar fracture and had underwent short-segment restoration and fixation in our department from Jan 2008 to Jan 2011,and had complete follow-up imaging were included.Cobb angles were measured on lateral thoracolumbar X-ray preoperatively,postoperatively and before removal of internal fixation.And these included the angle formed by vertebras that located above and below injured vertebrae (α angle),superior endplate of injured vertebrae and its superior vertebrae (β angle),inferior endplate of injured vertebrae and its inferior vertebrae (γ angle),inferior and superior endplate of injured vertebrae (δ angle).T-test was used to analyze these angles and their changes.And correlation analysis was used to analyze relationships between α angle change and other risk factors.Results:When compared with preoperative angles,the mean α angle,β angle,γ angle and δ angle were all significantly increased (p＜0.05) after the operation.The mean α angle and δ angle before the removal of internal fixation were both significantly smaller than those after the operation (p＜0.05),and the mean change ofα angle was-2.85 degrees.After the correlation analysis,we found significant correlations between the change ofα angle and postoperative correction curvature(-0.342,p=0.026),injured region in endplate(0.374,p=0.015),and change of the δ angle(0.231,p=0.041).Conclusion:There was significant loss in the correction curvature before the removal of internal fixation.And the loss was significantly associated with postoperative correction curvature,injured region in endplate,and change of the δ angle.

Host genes involved in lipid metabolism are differentially affected during the early stages of hepatitis C virus (HCV) infection.Here we demonstrate that artificial up-regulation of fatty acid biosynthesis has a positive effect on the replication of the HCV full-length replicon when cells were treated with nystatin.Conversely,the HCV RNA replication was decreased when fatty acid biosynthesis was inhibited with 25-hydroxycholesterol and PDMP(D-threo-1-phenyl-2-decanoylamino-3- morpholino-1-propanol).In agreement with these results,the expression level of GlcT-1(ceramide glucosyltransferase),a host glucosyltransferase in the first step of GSL (glycosphingolipid) biosynthesis,was found to be closely associated with the expression and replication of HCV RNA.On the other hand,the viral RNA can also activate GlcT-1 in the early stage of viral RNA transfection in vitro.To identify viral factors that are responsible for GlcT-1 activation,we constructed ten stable Vero cell lines that express individual HCV proteins.Based on the analyses of these cell lines and transient transfection assay of the GlcT-1 promoter regions,we conclude that HCV proteins,especially NS5A and NS5B,have positive effects on the expression of GlcT-1.It is possible that NS5A and NS5B stimulate transcription factor(s) to activate the expression of GlcT-1 by increasing its transcription level.

Objective To evaluate the effect of the noxious stimulation factor on γ-aminobutyric acid (GABA) distribution in dog spinal cord during propofol anesthesia.Methods Sixteen healthy mongrel dogs of both sexes,aged 12-18 months,weighing 10-12 kg,were randomly divided into 2 groups (n =8 each):noxious stimulation group (S group) and control group (C group).Anesthesia was induced with propofol 7 mg/kg.The animals were mechanically ventilated after tracheal intubation.Right femoral artery was cannulated for mean arterial pressure (MAP) and pulse rate monitoring.Anesthesia was maintained with propofol infusion at a constant rate of 70 mg· kg-1 · h-1.5 ％ formalin 300 μl was subcutaneously injected into the central region of tails in group S,while the equal volume of normal saline was injected instead of formalin in group C.MAP and pulse rate were recorded before injection of formalin or normal saline (T1) and after injection of formalin or normal saline (T2).The dogs were scarified by decapitation at 50 min of continuous propofol infusion and cervical 2-3 segments of the spinal cord were removed for determination of GABA level in different regions of the spinal cord (frontal horn,posterior horn,intermediate zone,frontal funiculus,posterior funiculus and lateral funiculus) by HPLC.Results MAP and pulse rate were significantly higher at T2 than at T1 in S group (P ＜ 0.05).There were no significant differences in GABA level among the different regions of the spinal cord in C group (P ＞ 0.05).Compared with C group,GABA level in the frontal horn and posterior horn was significantly increased (P ＜ 0.05),and no significant change was found in the other regions of the spinal cord in S group (P ＞ 0.05).Conclusion The noxious stimulation factor can induce an increase in GABA level in the frontal horn and posterior horn of dog spinal cord during propofol anesthesia.

Objective To evaluate the reliability of PainVision method for assessment of postoperative pain in patients undergoing gynaecological laparoscopy.Methods Twenty ASA physical status Ⅰ-Ⅱ patients,aged 30-45 yr,undergoing gynaecological laparoscopy under fentanyl-propofol-cisatracurium anesthesia,were studied.Pain intensity was simultaneously assessed using PainVision method and visual analog scale (VAS) at 12,24 and 48 h after surgery.PainVision was a new method for quantitative measurement of pain intensity using a painless electrical stimulation (PainVision PS-2100 device).Pain degree was calculated from two parameters,current perception threshold and pain compatible electrical current by using PainVision.The former parameter was defined by the lowest electrical current detected ; the latter parameter defined by the electrical current judged as being compatible with the intensity of ongoing pain.Results There was a significant positive correlation between pain degree calculated by PainVision method and VAS scores,and the correlation coefficient was 0.902 (P ＜ 0.01).Conclusion PainVision method can be applied for assessment of postoperative pain in patients undergoing gynaecological laparoscopy.
