ve To evaluate the effects of lipopolysaccharide (LPS) on hemeoxygenase-1 (HO-1) mRNA and HO-1 protein expression in isolated rat thoracic aorta (TA) and pulmonary tissue (PT), trying to explain the mechanism of different patho-physiological changes of systemic and pulmonary circulation in septic shock. Methods Twenty-four Wistar rats of either sex weighing 250-400g were sacrificed by cervical spine dislocation. Thoracic aorta and lung tissue were removed under aseptic condition. They were randomly divided into four groups of six animals each: control group (C) and three test groups in which TA and PT were incubated with LPS (1?g?ml-1) for 3h (group LPS3), 8h(group LPS8) and 24h (group LPS24) respectively. HO-1 mRNA expression and HO-1 protein expression in TA and PT were detected by RT-PCR and Western Blot. Results (1) As compared with that in group C, HO-1 protein expression in TA reached peak level in group LPS3, and the peak level was maintained in groups LPS8 and LPS24; while in PT HO-1 protein expression started increasing in group LPS3 and peaked in group LPS8 and tended to decline in group LPS24 but the difference in HO-1 protein expression between group C and LPS 24 was still significant. (2) As compared with that in control group, the HO-1 mRNA expression in TA peaked in LPS3, the peak level was maintained in LPS 8, but it returned to baseline level in LPS 24; while in PT HO-1 mRNA expression started increasing in LPS 3 and peaked in LPS 8 and returned to baseline level in LPS 24. Conclusions LPS can significantly enhance HO-1 mRNA and protein expression in isolated rat thoracic aorta and pulmonary tissue but the time-course is somewhat different between the two tissues. This may explain the different patho-physiologic changes of systemic and pulmonary circulation in septic shock.

Objective To determine the factors contributing to the development of deep vein thrombosis (DVT) in the lower extremity in patients after hip or knee arthroplasty and hip fracture internal fixation.Methods One hundred and forty-seven consecutive patients receiving hip or knee arthroplasty and hip fracture internal fixation from 2004 to 2005 were included in this study. Their age ranged from 33 to 92 years. Duplex color ultrasonic inspection was performed on veins of the bilateral lower extremities before operation and 2 weeks after operation for detection of DVT. The patients were divided into a DVT group and a DVT-free group based on the development of DVT after operation. Detailed perioperative clinical information about the patients, surgery and anesthesia was collected.Results Lower extremity DVT was found in 42.2% of the patients after operation, while the incidence of proximal DVT was 2.7%. Compared with the DVT-free group, the usage rate and dosage of ephedrine increased significantly, the duration of anesthesia was significantly longer, and the white blood cell count (WBC) on the 1st postoperative day and the highest WBC count were significantly higher in the DVT group(P<0.05). Logistic regression analysis indicated that the above factors were closely related to DVT.Conclusion Duration of anesthesia > 3 h, ephedrine administration and a marked increase in WBC count after operation are the risk factors for DVT in the lower extremities in patients after hip or knee arthroplasty and hip fracture internal fixation.

Objective:To survey the incidence of deep venous thrombosis (DVT) in high risk patients undergoing thoracotomy and observe the changes of hemostatic activity. Methods: Fifty-two consecutive patients (ages that ranged from 35 to 79, 34 men and 18 women) with lung or esophagus cancer were enrolled into this prospective trial. The patients included underwent major thoracic surgery from February 2003 to April 2003. Bilateral lower extremity duplex ultrasonography for DVT screening was performed 3-10 days post surgery in all 52 patients and 57 matched clinic normal controls. Venous blood was collected to determine fibrinogen(FIB), D-dimer(D-D), plasminogen activator inhibitor (PAI), antithrombin (AT), thrombin antithrombin complex (TAT), prothrombin time (PT),international normalized ratio(INR), and activated partial thromboplastin time (APTT) immediately before surgery, the third and tenth days postoperatively. No patient had a prior thromboembotic history. Risk factors for DVT were evaluated. Results: Of the 52 patients, 28 (53.8%) had an acute postoperative DVT detected in the calf. One patient died of suspected pulmonary embolism postoperatively. Plasma levels of FIB and D-D increased significantly up to 7 d after operation. AT level decreased significantly 3 d after operation and returned to normal 7 d latter. TAT increased significantly 3 d post operation and decreased to normal on day 7. PAI level was lowered 3 d after surgery, but increased significantly on day 7 compared with that on day 3. With the addition of risk factors related to thrombosis, the incidence of DVT was increased correspondingly. Conclusion: Of the patients undergoing major thoracic surgery,53.8% of them had a postoperative DVT by postoperative screening duplex ultrasound. In Chinese population, incidence of DVT appears to be high without prophylaxis, which is similar to other reports of westerners. These patients had a number of risk factors for the development of DVT, which include older age, overweight, hypertension, diabetes, and history of thromboembolism, etc. Prophylactic measures should be taken against postoperative venous thromboembolism in major thoracic surgery with high risk, including early mobilization, anticoagulant therapy with heparins, and intermittent pneumatic compression (IPC).

Objective:To analyze gene expression profiling of left ventricular myocardium in patients with chronic congestive heart failure(CHF)caused by rheumatic heart disease(RHD)with the normal controls in order to identify CHF associated target genes. Methods:The gene expression profiles of left ventricular myocardium from patients with CHF by RHD and normal controls were obtained from six human whole-genomic oligonucleotide microarrays(Affymetrix HG U133 Plus 2.0 GeneChip). GeneSpring software was used to identify the differentially expressed genes in both groups,and bioinformatic analysis was applied to analyze the target genes associated with CHF. Real-time PCR was carried out to validate the expression of three target genes. Results:We identified 102 target genes associated with CHF which were classified into 7 gene clusters. Microarray results were further confirmed by real time PCR for three genes. ATF3 was markedly down-regulated,IGFBP2 and NPPB were notably up-regulated in the left ventricular myocardium samples from CHF patients. Conclusion:A lot of differentially expressed genes,obtained by using the whole-genomic expression profiling technology,might be a contributory factor for the initiation and progression of CHF and it helpful for the understanding of underlying pathophysiological implications. Further investigation on these genes would provide a strategy to identify genetic markers and molecular events associated with CHF caused by RHD.

Objective:To investigate the effects of allicin on the proliferation, migration and angiogenesis of rat vascular endothelial cells (RVES), and to explore the influencing mechanism of allicin on epidural fibrosis.Methods:According to the results of preliminary experiments, RVECs were divided into control group (0 mg/L), low concentration group (25 mg/L), medium concentration group (50 mg/L) and high concentration group (100 mg/L). The morphology, viability, migration rate, cell cycle, apoptosis rate and cell lumen formation ability were measured using fluorescence microscope, AnnexinV-FITC double staining, PI/RN-asestaining, scratch assay and Transwell experiments test. Western Blot was used to measure the protein expression level of JAK2, STAT3, p-STAT3, PCNA, Bax and Bcl-2 protein. Using random number method, 36 adult male SD rats were divided into sham operation group, saline group and allicin group, with 12 rats in each group. Hematoxylin-eosin (HE) staining, Masson staining and immunohistochemical staining were used to analysis the epidural fibrosis in each group.Results:With the increase of concentration of allicin, cell viability, cell migration and lumen formation ability significantly lower than that of control group ( P<0.05). With the increase of allicin concentration, the percentage of cells in the G1 and S phases gradually decreased ( P<0.05), the percentage of cells in the G2 phase and the apoptosis rate gradually increased ( P<0.05), and the cells were blocked in the G2/M phase. With the increase of allicin concentration, the protein expression levels of JAK2, STAT3, p-STAT3, PCNA and Bcl-2 were gradually down-regulated ( P<0.05), while the protein expression level of Bax was gradually up-regulated ( P<0.05), the ratio of p-STAT3/STAT3 was decreased ( P<0.05), and the ratio of Bax/Bcl-2 was increased ( P<0.05). There was no death, infection or abnormal gait in all the experimental animals. Dense scar tissue could be observed in the extradural area of the sham operation group and the epidural area of the control group, but there was obvious space between the epidural scar and the dura mater in the allicin group, and the density of collagen, the number of blood vessels, and the protein density of p-STAT3 were significantly lower than those in the control group ( P<0.05). Conclusion:Allicin inhibits angiogenesis and the severity of epidural scar after laminectomy, and the mechanism may be through inhibiting the JAK2/STAT3 signaling pathway of vascular endothelial cells.
