Objective: To investigate mechanism on the restenosis after percutaneous transluminal coronary angioplasty (PTCA) with FSZ (Hirudo, Rhizoma Coptidis, Radix et Rhizoma Rhei, Radix Curcumae, Rhizoma Polygonati Odoroti, etc) by studying the protective effects of FSZ on arrhythmia and injury induced by ischemia and reperfusion.Methods:Rats were randomly divided into four groups and administered orally with FSZ. Left coronary artery ligature was used to form ischemia and reperfusion model. Lipid peroxidation (LPO), superoxide dismutase (SOD), cyclic adenosine monophosphate (cAMP), area of myocardial infarction, myocyte ultrastructural injury and occurrence of arrhymia were investigated.Results: FSZ could improve the changes in ST segment. In rats treated with FSZ, the levels of SOD were elevated while cAMP, LPO, and the specific viscosity of whole blood or plasma and the aggregation of the platelet were lowered, keep to improving the hemorheological changes. It also could antagonize the myocardial damage by myocardial ischemia or reperfusion reduced the area of myocardial infarction. Especially, Fufangshuizhijing Capsule reduced the area of left ventricular (LV) compared with the control group remarkably.Conclusion: FSZ could obviously antagonize arrhythmia and the injury induced by the ischemia and reperfusion, FSZ may scavenge oxygen free radical, regulate the second messenger, remarkably improve the local circulation to reduce the specific viscosity of whole blood of plasma and the aggregation of the platelet in rats, protect mitochondria safeguard the cardiac myocyte to treat PTCA.

Objective To explore the mechanism and effect of miR-146a on alveolar macrophages and to observe the changes of miR-146a expression in the LPS-induced alveolar macrophages. Method NR8383 alveolar macrophages were divided into LPS-stimulated group and control group, and the cells of former group were treated with LPS ( 1 μg/mL) and then incubated for 3 h, 6 h and 12 h, respectively. The level of TNF-α in the supernatant of cells was assayed by using enzyme-linked immunosorbent assay (ELISA), and the expression of miR-146a of cells was detected by using Real-Time PCR (TaqMan probe).Statistical analysis carried out by using SPSS 13.0 software package in which One-way ANOVA and Student's t-test were used. Results Compared with control group, the levels of TNF-α in the supernatant of cells were significantly increased 3 h, 6 h and 12 h after LPS challenge (P ＜ 0.01 ). The expression of miR-146a increased 6 h and 12 h after LPS stimulation in NR8383 cells( P ＜0.01 ), and it had an upward tendency.Conclusions The expression of miR-146a in alveolar macrophages increases after LPS-stimulation. It hints miR-146a may be involved in the regulation of the inflammatory responses produced by alveolar macrophages.

ObjectiveTo investigate the protective effect of transfected microRNA-146a (miR-146a) on mice with sepsis-induced acute lung injury (ALI) in vivo.Methods Twenty-four healthy male BALB/C mice were randomly divided into sham group, sepsis group, transfection group and transfection control group, eachn = 6. Mice in transfection group were given miR-146a agomir loaded by in vivo-jetPEITM via airway before reproduction of model, and mice in transfection control group were given negative control loaded by in vivo-jetPEITM only via airway. The septic model was reproduced by cecal ligation and puncture (CLP) 12 hours after transfection , and the mice in the sham group underwent laparotomy and closure only without ligation and puncture of the cecum. The mice of each group were sacrificed at 24 hours post-operation. The expression of miR-146a in lung tissue was determined by real time fluorescence quantitative reverse transcription-polymerase chain reaction (RT-qPCR), and the quantity of tumor necrosis factor-α (TNF-α) in the bronchial alveolar lavage fluid (BALF) was determined with enzyme-linked immunosorbent assay (ELISA). The wet/dry ratio of lung (W/D) was determined. The pathohistological changes in the lung were observed and scored. Results The expression of miR-146a showed a significant increase in sepsis group, transfection group and transfection control group, which were (3.56±0.43), (27.64±3.46) and (3.72±0.54) folds of that in sham group, respectively (P< 0.05 orP< 0.01). The miR-146a expression in transfection group was significantly increased compared with sepsis group and transfection control group (bothP< 0.01), but no statistical difference in the expression was found between sepsis group and transfection control group (P> 0.05). Compared with the sham group, higher level of TNF-αin the BALF was found in the sepsis group, transfection group and transfection control group (ng/L: 511.65±43.47, 305.74±34.76, 492.27±42.21 vs. 50.72±7.23, allP< 0.01). The level of TNF-α in transfection group was significantly lower than that in sepsis group and transfection control group (bothP< 0.01). Compared with the sham group, the W/D ratio of lung in sepsis group, transfection group and transfection control group showed a significant increase (6.11±0.32, 5.02±0.29, 6.05±0.43 vs. 4.18±0.10, allP< 0.01). The W/D ratio of lung in transfection group was significantly lower than that of sepsis group and transfection control group (bothP< 0.01). The lung injury score of transfection group was significantly lower than that of sepsis group and transfection control group (6.12±0.75 vs. 10.53±1.52, 9.73±1.08, bothP< 0.01).Conclusions miR-146a agomir loaded by in vivo-jetPEITM instillation into airway was able to increase the expression of miR-146a in the lung tissue of septic mice. Up-regulation of miR-146a inhibit the release of the inflammatory cytokine TNF-α stimulated by sepsis, and alleviate inflammatory reaction and lung tissue injury in mice with sepsis-induced ALI.

BACKGROUND: Autologous bone graft was always applied to repair bony cavity defect produced by benign bone tumor.OBJECTIVE: Taking autogenous bone graft for repairing bony cavity defect caused by bone tumor or tumor-like pathological change as control standard, to observe transplantation of deproteined bovine cancellous bone combined with autogenous red marrow in occluding the residual cavity and the density of newly formed bone.DESIGN: A randomized grouping design, controlled observation SETTING: Department of Orthopaedics, the 175 Hospital of Chinese PLA PARTICIPANTS:We recruited 175 cases of bony cavity defect who received treatment in the Department of Orthopaedics, the 175 Hospital of Chinese PLA from July 1993 to July 1998. They were randomly assigned into two groups: experimental group and control group. There were 63 cases treated in the experimental group. The average disease-suffering time was (6.2±2.1) months and bone defect was (136±30) mm3. There were 62 cases treated in the control group. The average disease-suffering time was (6.1±2.3)months, and bone defect was (133±37) mm3.METHODS: Deproteined bovine cancellous bone combined with autogenous red marrow was transplanted in the experimental group and autologous bone graft was applied in the control group. We curetted tumor completely, cauterized the wound with alcohol of 0.95 volume fraction, then curetted the area of cauterization to make it bled. Bone graft was applied.The quantity of implanted bone should be abundant, and disposed compactly. The X-ray films of the first week after operation were used as a standard for density of new bone growth. X-ray films were taken at the 3rd,6th and 8th months postoperatively, and the X-ray films of the eighth months after operation were used as a standard.MAIN OUTCOME MEASURES: To compare the bone union in two groups with a standard of residual cavity occluding and density of bone growth.RESULTS: All patients were followed up for an average of 20 months.One case was lost six months after operation. And two cases were lost eighteen months after operation respectively in the experimental group and control group. After 8 months of operation, residual cavities of bone defect of 44 cases in experimental group and 46 cases in control group were disappeared. Palingenetic bone fused with left bone organization. Its density was the same as or higher than normal bone organization. Residual cavities of 12 cases in experimental group and 10 cases in control group were disappeared basically. The density of palingenetic bone was approximate to normal bone organization. To compare with autologous bone graft, deproteined bovine cancellous bone and an autogenous red marrow had an identical effect for repairing bony cavity defect.CONCLUSION: Bony cavity defect produced by benign bone tumor is often repaired by bone transplantation. To explore the substitutable grafting materials of autogenous bone in this study, a composite material composed of deproteined bovine cancellous bone and an autogenous red marrow (DBCAM) is applied to repair the bony cavity defect.

Objective To evaluate the influnce of atrial fibrillation(AF)/atrial flutter on the mortality and prognosis of patients with AMI. Methods A total of 297 consecutive patients were studied from Jan.2001 to Dec. 2005 and were categorized into 2 groups according to the presence or absence of AF/atrial flutter. The 30 d and 6 mo mortalities, Killip Grades, cardiogenic shock, arrhythmia and left ventricular ejectory functional (LVEF) 6 months after AMI with Doppler US between the 2 groups were compared. Results The incidence of AF/atrial fluttler was 12.5% with older age, higher Killip Gorade, higher CPK peak, higher rates of previous myocardial infarction and multivascular involvement than those without AF/atrial flutter. The short and medium-term mortalities in AF/atrial flutter group were both significantly higher than those of non-AF/atrial flutter group(P

Objective To explore the perioperative management and surgical outcomes of fracture-dislocation of the upper cervical spine complicated with vertebral artery injury.Methods We retrospectively analyzed the clinical data of 19 patients diagnosed with fracture-dislocation of the upper cervical spine complicated with vertebral artery injury who had been treated at our department from January 2008 through December 2012.They were 14 males and 5 females,aged from 22 to 53 years (mean,35.2 years).All the patients had fractures of the atlas and/or axis,and disordered atlanto-axial relationship as well.According to Frankel grading system,8 cases were Grade D and 11 Grade E.The cervical posterior fixation with pedicle screws was adopted for all and hemostasis was conducted for those with bleeding from the broken vertebral artery.Their Frankel grade,Japanese Orthopedic Association (JOA) score and visual analogue scale (VAS) score were compared between preoperation and final follow-up.Results Intraoperative hemorrhage occurred in 2 patients from the injured vertebral artery.Hemostasis was achieved through direct tamponade with bone wax and gelatin sponge in one and through endovascular intervention after bleeding control by direct tamponade in another.Neither of them presented with symptoms of posterior circulation ischemia after operation.The mean operation time was 153.5 min,and the mean blood loss was 542.1 mL.All the patients were followed up for an average time of 28 months.Bony union was obtained in all after an average time of 13.5 weeks.Follow-ups revealed no ischemic stroke in this series.Symptoms of transient ischemic attack,like transient dizziness and blurred vision,appeared in 2 patients.At the final follow-up,all the patients were assessed as Frankel Grade E.Their mean JOA and VAS scores were significantly improved from 8.1 ± 1.2 and 7.0 ± 1.7 preoperatively to 12.7 ± 1.6 and 1.3 ± 1.2,respectively (P ＜ 0.05).Conclusions Angiography examination is routinely indicated for the patients with fracture-dislocation of the upper cervical spine perioperatively.Preoperative evaluation of the vertebral artery and its adjacent structures and effective intraoperative hemostasis can avoid uncontrollable bleeding during operation,reduce postoperative complications,and improve surgical outcomes.
