Clinical Medicine of China 2010;26(7):707-709
Objective To compare the efficiency of repairing perimembranous ventricular septal defect (VSD) with continuous stitching to that with interrupted stitching. Methods Of the 158 patients with perimembranous VSD ( 54% males) ,102 ( 65% ) patients underwent the repairing of continuous stitching (continuous group) ,and 56 patients underwent interrupted stitching (interrupted group). All the surgeries were performed under hypothermic cardiopulmonary bypass. Results The cardiopulmonary bypass time and aortic cross-clamp times were (31 ±14) mins and (18 ±12) mins in the continuous group, which was significantly less that those of (42 ± 16) mins and (25 ±11) mins in the interrupted group (t =4.49 and 3. 61 .respectively ,P <0. 05) . No case was died. The main complications involved temporary M atrioventricular block (AVB) of two cases (1 case in each group),which disappeared after 1 week. There were two remnants remaining leak (n =2) which was less than 3 mm and automatically cured after 3-6 months. Complete right bundle branch block(CRBBB) occurred in 3 cases in the continuous group and 6 cases in the interrupted group,of which 3 disappeared after 1 month and 2 disappeared after 12 months. The outcome was good in all cases after 1-3 years follow up. Conclusions Continuous stitching showed a shorter cardiopulmonary bypass and aortic cross-clamp times, and reduced the CRBBB.

BACKGROUND: Studies in recent years have suggested the involvement of chemoattractant cytokines in the recruitment of peripheral blood cells to the injured spinal tissue. Monocyte chemoattractant protein-1(MCP-1) belongs to the CC-type chemokines and is capable of specific chemotactic attraction of the macrophages.OBJECTIVE: To observe MCP-1 expression in the serum of patients with acute spinal cord injury and explore the possible mechanism of secondary spinal cord injury.DESIGN: A non-randomized and controlled concurrent pilot study.SETTING and PARTICIPANTS: Eight patients with acute incomplete spinal cord injury and 8 with compression fracture of the spine were treated in the Department of Orthopaedics, Renmin Hospital of Wuhan University during the period from January 2001 to December 2002. Another 8 healthy subjects were included as the controls.METHODS: In the next morning after hospitalization, totally(8-10) mL of fasting peripheral venous blood was collected from the patients and the serum separated for determination of MCP-1 level with enzyme-linked immunosorbent assay(ELISA) . Serum MCP-1 level was also measured in the healthy subjects in the same manner.MAIN OUTCOME MEASURES: Serum level of MCP-1 in each group.RESULTS: Serum levels of MCP-1 in the healthy subjects, patients with compression fracture of the spine and those with acute incomplete spinal cord injury were(124 ± 15), (184 ±21) and(428 ± 11) ng/L, respectively, with significant differences between any two groups( P < 0.01 ).CONCLUSION: MCP-1 may induce secondary inflammation by recruiting inflamnatory cells to the injury site and thus aggravate the spinal cord injury.

BACKGROUND: Under wear particles stimulation, mononuclear macrophages, fibroblasts, and osteoblasts can produce a large amount of inflammatory factors, leading to periprosthetic osteolysis. But the precise mechanisms remain unclear. OBJECTIVE: To analyze the molecular biological mechanism underlying osteolysis induced by titanium wear particles . RESULTS AND CONCLUSION: Cleaned titanium particles stimulation induced an unbalanced ratio of RANK mRNA to OPG mRNA. Over-expressed RANK bound to RANK ligand and promoted osteolysis. No RANK mRNA expression was detected in the LPS group, but OPG mRNA expression was transiently increased at 4 hours. NF-κB/inflammatory cytokine, rather than RANK/OPG, is the main signal pathway for LPS to induce osteolysis. After LPS binding to titanium particles, these two signal mechanisms, RANK/OPG and NF-κB/inflammatory cytokine, have synergistic effects during artificial joint loosening.
