Objective To explore the relationship among plasma cytokines’ level, adhesion molecules expression and skin damage in patients with chronic venous insufficiency (CVI) of lower extremities.Methods In 32 patients with CVI and 8 normal individuals as control, blood TNF ?, IL 1? and IL 2R were assayed with ELISA method; serum endothelial cell intercellular adhesion molecule 1(EC ICAM 1), polymorphonuclear CD 18 (PMN CD 18 ) and polymorphonuclear CD 11b (PMN CD 11b ) were assayed with immunohistochemical method; and ultrastructure of diseased veins was examined by electroscope.Results The results showed that the level of plasma TNF ? and IL 1? increased remarkably in Class 2-3 compared with Class 1 and control ( P 0.05) . The index of EC ICAM 1 and PMN CD 11b positively expression increased remarkably in Class 2-3 compared with that in Class 1 and control. The index of PMN CD 18 expression in Class 2-3 and Class 1 was greatly higher than that in control ( P

Objective To discuss the endothelial cell which was modified by exogenous anticoagulant genes contribute to the increase of antithrombosis activity of lined vascular prosthesis and the influence to other physiological functions of endothelial cells. Methods This summarized paper was made on literature review of recent years.Results The transfection of genes, including plasminogen activator (t-PA, u-PA, Urokinase), thrombomoduline (TM) and hirudin, etc, to endothelial cells resulted in not only the increase of antithrombosis activity of local vascular, but also the decrease of endothelial cell function in adherence and proliferation.Conclusion The increase of antithrombosis activity of lined vascular prosthesis has been done by exogenous genes. However, this technique ought to be studied, intensively.

Objective:To clarify the relationship between postoperative tumor recurrence and the type and dosage of immunosuppressants in patients undergoing liver transplantation.Method:A retrospective analysis was conducted on the clinical data of patients who underwent liver transplantation for liver cancer from September 2007 to January 2019 at the Department of Hepatobiliary Surgery, First Affiliated Hospital of Chongqing Medical University. According to whether there was tumor recurrence after liver transplantation, the patients were divided into the case group and the control group. The etiology, alpha-fetoprotein level, Child-Pugh score, model for end-stage liver disease (MELD) score, and cancer nodules, number of tumors, diameter of largest cancer nodule, microvascular infiltration (MVI), large vessel infiltration, Edmondson grade of tumor differentiation, postoperative immunosuppression regimen, and blood trough concentration of tacrolimus or cyclosporine were compared between the two groups. The effects of calcineurin inhibitor (CNI) exposure in groups of patients on tumor recurrence were compared, and statistically significant factors were included in the Cox regression analysis. Using the BCLC staging standard of liver cancer, all the subjects were stratified, and the influence of CNI exposure on tumor recurrence was further analyzed.Results:This study included 50 patients. There were 15 patients in the case group, aged (45.8±8.2) years, with 13 males (86.7%). There were 35 patients in the control group, aged (45.4±12.0) years, 31 males (88.6%). The diameter of the largest cancer nodule in the case group was significantly larger than that in the control group [(5.9±3.0) cm vs (3.5±1.8) cm, P<0.05]. The tacrolimus exposure levels in the case group at 14 d after operation were significantly higher than the control group[(11.7±7.7)ng/ml vs (5.9±3.0)ng/ml, t=2.48], 1 month after operation [(12.2±4.5) ng/ml vs (7.8±4.3) ng/ml, t=2.82], 9 months after operation [(6.9±4.0) ng/ml to (4.7±2.0) ng/ml, t=2.21] and the area under the curve at 1 year after operation [(100.1±21.1) vs (74.4±19.2), t=3.66], all P<0.05. Survival analysis showed that the cumulative tumor-free survival rate of the CNI high-exposure group was significantly lower than that of the CNI low-exposure group (52.2% vs 85.2%, χ 2=6.52, P<0.05). Multivariate analysis using the Cox proportional hazards regression model showed that the largest cancer nodule diameter ( RR=1.23, 95% CI: 1.01-1.60) and high CNI exposure ( RR=4.02, 95% CI: 1.10-14.74) were independent risk factors for tumor recurrence after liver transplantation. Stratified analysis showed that of the 17 patients with BCLC stage B, 6 patients (66.7%) with high CNI exposure developed tumor recurrence, while only 1 patient (12.5%) with low CNI exposure developed tumor recurrence. The difference was statistically significant ( P<0.05). Survival analysis showed that the cumulative tumor-free survival rate of patients with CNI high-exposure was significantly lower than that of patients with CNI low-exposure (33.3% vs 87.5%, χ 2=5.74, P<0.05). Of the 8 patients with BCLC stage C, 4 patients developed tumor recurrence with CNI high-exposure (100.0%). There was no tumor recurrence in patients with low CNI exposure. The difference between groups was statistically significant ( P<0.05). Survival analysis showed that the cumulative tumor-free survival rate of patients with high CNI exposure was significantly lower than that of low CNI exposure (0 vs 100.0%, χ 2=6.80, P<0.05). Conclusions:Tumor recurrence after liver transplantation was not significantly related to the type of immunosuppressant used. High CNI exposure was a risk factor for tumor recurrence after liver transplantation.

Objective To investigate the irradiating effect of low intensive microwave(LIM) on pathological process of blood vessel restenosis(RS) and assess the probability of LIM irradiation to prevent was used RS.(Methods Forty-four) male healthy New Zealand rabbits were randomly divided into 2 groups.Fogarty catheter traumatize to the tunica intima of iliac artery so as to establish RS models.Two thousand four hundred and fifty MHz microwave with different power of 2,5 and 10 mW/cm~2 was used,locally to irradiate EIA in irradiating group(1 h/d).Specimens were obtained at different time of 3,7,14 and 28 d after operation.Morphological changes of tissues were observed with HE and EF staining and the area of tunica intima,tunica media and the rate of cavity stenosis were analyzed with image analysis system;apoptosis was detected with TUNEL;phenotype and microstructure of VSMC were observed with TEM.Results After microwave irradiating,inflammatory reaction in early period was suppressed,mural thrombus decreased,the proliferation and migration of VSMC depressed,the area of tunica intima and the rate of cavity stenosis obviously reduced comparing with the control group(P0.05).At other different time,however,the rate of apoptosis cells in irradiating groups obviously increased than that of the control group(P

AIM: To provide experimental evidence for gene therapy of thrombophilia disease, we constructed the eukaryotic expression plasmid with human thrombomodulin (hTM) gene and observed the alteration of hTM expression on the surface of human umbilical vein endothelial cells (HUVECs) with and without the reconstructive plasmid. METHODS: The whole expressive fragment of hTM gene was amplified by PCR from human genome. Both hTM gene and pcDNA3.1(+)/neo empty vector was digested by HindⅢ and EcoRⅠ. Two digested fragments were ligated into pcDNA3.1/hTM with T_4DNA ligase. After identifying, the reconstructive plasmid transfected into HUVECs using lipofectin. The hTM antigen on the HUVECs was detected by immunohistochemistry. RESULTS: The hTM reconstructive plasmid was confirmed by double endonuclease redigesting and sequencing. About 10% HUVECs were transfected by pcDNA3.1/hTM plasmid with lipofectin and the high-level hTM was detected on the transfected cells. CONCLUSION: We constructed the pcDNA3.1/hTM plasmid successfully, and it could be expressed on the HUVECs. [
