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.

There has been an ongoing search for clinically acceptable methods for the accurate, efficient and simple diagnosis and prognosis of hepatocellular carcinoma (HCC). Optical spectroscopy is a technique with potential clinical applications to diagnose cancer diseases. The purpose of this study was to obtain the optical properties of HCC tissues and non-tumorous hepatic tissues and identify the difference between them. A total of 55 tissue samples (HCC tissue, n=38; non-tumorous hepatic tissue, n=17) were surgically resected from patients with HCC. The optical parameters were measured in 10-nm steps using single-integrating-sphere system in the wavelength range of 400 to 1800 nm. It was found that the optical properties and their differences varied with the wavelength for the HCC tissue and the non-tumorous hepatic tissue in the entire wavelength range of research. The absorption coefficient of the HCC tissue (1.48±0.99, 1.46±0.88, 0.86±0.61, 2.15±0.53, 0.54±0.10, 0.79±0.15 mm(-1)) was significantly lower than that of the non-tumorous hepatic tissue (2.79±1.73, 3.13±1.47, 3.06±2.79, 2.57±0.55, 0.62±0.10, 0.93±0.16 mm(-1)) at wavelengths of 400, 410, 450, 1450, 1660 and 1800 nm, respectively (P<0.05). The reduced scattering coefficient of HCC tissue (5.28±1.70, 4.91±1.54, 1.26±0.35 mm(-1)) and non-tumorous hepatic tissue (8.14±3.70, 9.27±3.08, 2.55±0.57 mm(-1)) was significantly different at 460, 500 and 1800 nm respectively (P<0.05). These results show different pathologic liver tissues have different optical properties. It provides a better understanding of the relationship between optical parameters and physiological characteristics in human liver tissues. And it would be very useful for developing a non-invasive, real-time, simple and efficient way for medical management of HCC in the future.

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 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.
