Objective To analyze the correlation of acute pancreatitis with hyperlipemia and C reactive pro-tein. Methods 42 patients with acute pancreatitis with hyperlipemia were divided into two groups of SAP group and MAP group under the diagnostic code. The blood fat and CRP were compared between the two groups, also the scores of APACHE Ⅱ , Ranson and CT were measured. Results The CRP and TG in group SAP compared with those in group MAP had significant difference(P<0.01),but the CHOL has no-difference;the scores of APACHEⅡ , Ranson and CT after control lipid in 42 patients were significantly' different( P < 0.05). Conclusion Hyperlipe-mia is one risk factors of the AP;combined with the CRP, it can be one evaluating index of the severity.

Objective To study the value of microwave coagulation therapy for liver malignant tumors.Methods Under local anesthesia,19 cases with hepatic malignant tumors treated with microwave knife under CT-guided.Results There were totally 23 tumors in 19 cases,13 tumors with≤3.5 cm in diameters were destroyed absolutely after the first treatmet,10 tumors among them were followed-up for 6-12 months and no recurred.10 tumors with＞3.5 cm in diameters treated at multiple points or angle,3～6 months later,CT showed that the tumors were destroyed completely in 6 and mostly in 4,by the hot condensate treatment secondly,3 tumors of 4 were destroyed completely 3 months later.There were no obvious complications.Conclusion The therapeutic effect under CT-guided microwave coagulation therapy for liver tumor which are ≤3.5 cm in diameter of the tumors is very reliable,the tumors＞3.5 cm in diameter can be destroyed mostly or completely by microwave treatment.

Objective To evaluate the role of temporary arteriovenous fistula(AVF) in the treatment of acute deep venous thrombosis(DVT) with Amplatz thrombectomy device(ATD). Method Seventy-six cases of acute DVT underwent mechanical thrombolysis with ATD, in which 50 cases received a temporary AVF after interventional therapy. Result One case died of pulmonary embolism. Ipsilateral limbs swelling subsided and pain alleviated in the remaining 72 cases since first post-operative day. Secondary contralateral DVT developed in 2 cases on the 7th post-operative day. The patency of temporary AVF was 86%(43/50). Sixty-eight cases (90.7%) were followed-up for 10~42 months post-operatively with limbs swelling completely subsided in 59 cases and ameliorated in 6 cases. Secondary inferior vena cava thrombosis developed in one case and 2 cases died of unrelated diseases. Conclusion Temporary AVF increases blood flow volume and blood velocity in the thrombectomized vein segment to improve the vein patency, hence is a valuable auxiliary means of ATD.

Objective To explore the clinical significance of interventional treatment of iliac vein compression syndrome(IVCS). Methods Percutaneous transluminal angioplasty(PTA) was performed in 40 cases. Thirty three cases underwent endovascular stent implantation and 27 cases underwent second stage left saphenous vein ligation and stripping and the valves of left femoral veins narrowing. Thirty one cases were followed up postoperatively and the duration was 6～66 months (mean 28 months). Results The dilation of iliac veins was successful in 36 cases and there were good efficacy in all patients when they discharged from hospital. Followed up during post operation, all the limbs ulcers were cured and varicose veins disappeared. The skin pigmentation disappeared in 17 of 19 cases and markedly relieved in 2 cases. Left lower limb swelling disappeared in 15 of 17 cases and relieved in 2cases. Conclusion There is good efficacy in the interventional treatment of left iliac vein lesions, but second stage procedures should be performed in secondary lesions of saphenous veins and valves of femoral veins.

Objective To investigate the effect of oncolytic adenovirus vector SG600-IL24expressing human melanoma differentiation associated gene-7 (mda-7/IL-24) on hepatocellular carcinoma cell lines with different metastatic potential of HepG2, SMMC7721, MHCC97L and normal liver cell line LO2. Methods The oncolytic adenovirus SG600-IL24 which carrying mda-7/IL-24 gene was transfected into hepatocellular carcinoma cell lines and normal liver cell line. The mRNA and protein expression of mda7/IL-24 in HepG2, SMMC7721, MHCC97L and LO2 cell lines was confirmed by RT-PCR,ELISA assay and Western blot respectively. MTT assay and flow cytometry were used to study tumor cell proliferation and cell cycle in vitro. Hoechst33258 and flow cytometry were studied to indicate the apoptosis effects. Results It was confirmed by RT-PCR, ELISA assay and Western-blot that the exogenous mda-7/IL-24 gene was highly expressed in HepG2, SMMC7721, MHCC97L and LO2 cell lines. MTT and apoptosis detection indicated that MDA-7/IL-24 can induce the growth suppression (the inhibition rate was 75% ±2. 5% ,86% ±3. 5% ,and promotes apoptosis ( the apoptosis rate was 56. 5% ± 4. 0% , 34. 4% ± 2. 0% , 43. 3% ± 2. 5%cell lines at G2/M phase ( the blocking rate was 35. 4% ± 4. 2% , 40. 5% ± 5. 0% , 42. 0% ± 5. 0%metastatic potential hepatocellular carcinoma cell lines but not in normal liver cell line.Conclusions Oncolytic adenovirus vector SG600-IL24 can selectively induce growth suppression, promote apoptosis in hepatocellular carcinoma lines in vitro but not in normal liver cell LO2.

Objective To evaluate interventional therapy for Budd-Chiari syndrome. Methods IVC venography was first carried out, the obliteration or stenosis in the IVC was opened or dilated with the hard tip of guid wire or puncture needle and balloon, then a stent was implanted. Results The procedure was successful in 271 out of 312 cases including IVC intervention in 260 cases, and hepatic vein intervention in 11 cases. IVC stent was used in 195 cases and hepatic vein stent in 1 case. There was no pulmonary embolism happened, acute renal failure occurred in 6 cases, hepatic coma in 1 case and acute heart failure in 21 cases. One patient died in this group and 2 were complicated with acute IVC thrombosis. Follow up of 6 to 104 mos was made in 203 cases with recurrence found in 21 cases. Conclusion Interventional therapy is indicated for most types of BCS with safe and effective results.

Objective To investigate the impact of 1,25(OH)2D3 on histological changes and activation of STAT3 in BLM?induced pulmonary fibrosis mice. Methods 30 male C57BL/6 mice were randomly divided into control group ,BLM group and BLM+VD group. Mice in BLM group and BLM+VD group received intratracheal injection of BLM(3 U/kg). Control group were intratracheally injected equal volume of sterile saline. From the first day after the surgery,mice in BLM+VD group received intraperitoneal injection of VD (5μg/kg·d). After 21 days, H&E and Masson′s trichrome staining were carried out. Aschroft score were used to evaluate histological changes in lungs. IL?6,IL?4 and INF?γin BALF were assessed by Elisa. p?STAT3,α?SMA and Collagen I were detected by western blot (WB) and immunohistochemistry. Results Fibrosis score and level of α?SMA,Collagen I in BLM group were significantly higher than that in control group (P < 0.05). However ,treatment with VD effectively at?tenuated fibrosis (P<0.05). IL?6 and IL?4 increased while INF?γwas decreased in BALF of BLM group (P<0.05). VD could ameliorate these changes. Upregulation and neuclear translocation of p?STAT3 were observed in BLM group,while VD intervention could inhibit phosphorylation of STAT3. Conclusions VD attenuate BLM?induced pulmonary fibrosis and regulate inflammatory cytokines probably by blocking STAT3 activation.

Objective To explore the appropriate method for mechanical thrombectomy, selection of vena cava filter and its duration in place. Method Fifty-five cases of severe acute deep vein thrombosis of the lower limbs were enrolled. Vena cava filter was first placed, then thrombectomy was performed with Amplatz thrombectomy device (ATD). The iliac vein lesions were dilated by balloon followed by temporary arterivenous fistula construction. Result Procedures were all successful in 52 cases, iliac vein stenosis was found in 47 cases and dilated by balloon. Permanent vena cava filters were placed in 20 cases while temporary in 32 cases. Fifty cases were followed-up for 3～30 monthes. Tumefaction disappeared in 46 cases leaving no after thrombosis syndrome. Conclusion This comprehensive modality is effective, less traumatic and of quick recovery. During the procedure, possible residual thrombi should always be under close attention and stenosis in iliac veins be confirmed by repeated venography. In most cases, placing a temporary vena cava filter was the best choice.
