Objective To study the FT-IR fingerprint characteristics of Hedysari Radix from 8 producing counties in Gansu Province; To provide references for identification and application of Hedysari Radix in different producing counties. Methods FT-IR fingerprints of 110 batches of Hedysari Radix from 8 producing counties in Gansu Province were collected in the wave number range of 4000–400 cm-1. The common pattern of the fingerprints were analyzed, and the similarity analysis were used to analyze the FT-IR fingerprints of Hedysari Radix from 8 producing counties. The FT-IR fingerprint characteristics of Hedysari Radix from 8 producing counties in Gansu Province were compared. Results The rank of average similarity of FT-IR fingerprints of Hedysari Radix from 8 producing counties was Tanchang County > Li County > Xihe County > Wudu District > Zhang County > Min County > Longxi County >Weiyuan County, and Hedysari Radix from Longxi County and Weiyuan County were very different from other producing counties. The FT-IR fingerprints of Hedysari Radix from Longnan City (Tanchang County, Li County, Xihe County and Wudu District) were similar, and the average similarity was relatively high; while that from Dingxi City (Zhang County, Min County, Longxi County and Weiyuan County) were similar, and the average similarity was relatively low. Hedysari Radix from every producing county had a significant and unique FT-IR fingerprint characteristic. Conclusion The identification and application of Hedysari Radix from 8 producing counties in Gansu Province can be realized according to FT-IR fingerprint characteristics.

OBJECTIVETo screen out the HAb18G/CD147 binding peptides and find out an antagonist against hepatoma invasion.

METHODSHAb18G/CD147 was purified by affinity chromatographic method and the antigen binding peptides acquired by bio-panning a phage-displayed 12-peptide library. After obtaining the sequence of the selected phage-displayed peptides, all the 9 peptides were synthesized by solid-phase method and identified by mass spectrograph. The peptides' anti-metastatic function was tested by Boyden Chamber assay.

RESULTSThe purified HAb18G/CD147, identified by Western blot (molecular weight about 65 kd) could be used to bio-pan the phage-displayed peptide library. After 3 rounds of bio-panning, 9 positive phage clones were selected and sequenced. The synthesized peptides had uneven inhibitory activities and three of them were able to markedly inhibit the hepatoma cell invasion (P < 0.01). The most effective peptide decreased by 90.1% of hepatoma cells migrating through the Boyden Chamber membrane as compared with the control.

CONCLUSIONBio-panning the phage-displayed peptide library can be used successfully to screen out the antigen binding peptides. Hepatoma metastatic potential can be inhibited by peptide antagonist which could be a good foundation of developing peptide therapeutic agent against hepatoma metastasis.

Objective To explore the significance of urine deoxypyridinoline to diagnosis on osseous metastasis of lung neoplasms.Methods.182 cases with lung carcinoma was divided into two groups.One group was case with osseous metastasis,the other group was case without osseous metastasis,uDPD/uCr, uCa/Cr,sCa and sAKP in two groups were respectively compared.Sensitivity and specificity of these indexes to diagnosis on osseous metastasis of lung cancer were also acalculated and compared.80 cases without osseous metastasis were follow-up for 6 months.Results The ratio of uDPD/uCr with osseous metastasis group[(12.35?2.65)nmol/mmol]was significantly higher than that of without osseous metastasis group [(7.76?2.11)nmol/mmol](t=2.46,P

Objective To detect the feasibility of magnetically labeled swine bone marrow mesenehymal stem cells(MSCs)with SHU 555A combined with poly-L-arginine(PLL),under MR imaging in vitro and in vivo.Methods Swine mesenehymal stem cells were isolated and culture-expanded 3 passages in vitro,then magnetically labeled by incubation with SHU 555A(25?g Fe/ml,Resovist,Schering)for 24 hours with 750 ng/mL poly-L-lysine(PLL;average MW_275 kDa)added 1 hour before incubation.Cellular iron incorporation and detention at 0 d,4 d,8 d,12 d,16 d,20 d after labeling was qualitatively assessed using Prussian blue and quantified at atomic absorption spectrometry.Cell viability was assessed by trypan-blue exclusion test.Cell suspensions underwent MR imaging with T_1-and T_2-weighted spin-echo and fast field-echo sequences on a clinical 1.5 T MR system.At last,1?10~6 SHU 555A labeled and unlabeled MSCs were transextracardially implanted into the infracted and normal myocardium approximately 2 week following the ligation of left anterior descending coronary artery in 1 swine respectively,and finally performed 1.5-T MRI within 1 week after infarction.Results①Intracytoplasmic particles stained with Prussian blue stain were detected for all cells with mean cellular iron content of(13.13?2.30)pg per cell.With division of stem cells, the stained particles decreased gradually with iron content(0.68?0.20)pg per cell.at 16 days after labeling, approximately to the prelabeled baseline values.(0.21?0.06)pg per cell(P＞0.05).The viability of the labeled cells at various time points were not significantly different with that of nonlabeled cells(P＞0.05).②MR images showed signal intensity changed most obviouly in T2*WI in vitro.The percentage change of signal intensity increased with increasing cell numbers,and decreased with the time.As few as 5?10~4-1?10~5 cells could be detected by using this approach.③Two injected sites containing MR-MSCs were detected in vivo,presentingas low signal intensity areas with the T_2*WI scanning sequence.Conclusion Swine bone marrow MSCs can be labeled with SHU555A-PLL and depicted with a standard 1.5-T MR imager in vitro and in vivo.(J lntervent Radiol,2007,16:115-121)

Objective To investigate the association of the levels of serum oxidized low density lipoprotein ( ox -LDL ) , C -reactive protein ( CRP) and matrix metalloproteinase -9 ( MMP -9 ) of atherosclerotic cerebral in infarction patients with the carotid intima -media thickness ( IMT) and the stability of plaque.Methods A total of 110 patients with atherosclerotic cerebral infarction (ACI, group A),90 patients with lacunar infarction ( LACI, group B ) and 100 healthy volunteers ( group C) were selected.The levels of serum ox -LDL,CRP and MMP-9 by enzyme linked immunosorbent assay (ELISA) were detected and the IMT and the plaque formation were measured.Results The serum ox-LDL, CRP,MMP-9,IMT and the detection rate of group A and B were signifi-cantly higher than those of group C ( P<0.05 );serum ox-LDL, CRP, MMP-9 , smoking were the independent risk factors of the formation of carotid plaque in cerebral infarction patients ( P<0.05 ).The levels of serum ox -LDL, CRP, MMP -9 in the cerebral infarction patients without plaque group , with stable plaque group and unstable plaque group increased in turn ( P<0.05 ).Conclusion The increased levels of serum ox -LDL, CRP, MMP -9 in cerebral infarction patients are closely related with the bodiness of carotid artery IMT , the formation of the plaque and the stability.

BACKGROUNDCatheter-directed thrombolysis (CDT) for deep venous thrombosis (DVT) of the lower extremity has good effect, but whether iliac vein stent placement after thrombolytic therapy is still controversial. The goal of this study was to evaluate the efficacy of stent placement in the iliac vein following CDT in lower extremity DVT.

METHODSThis was a single-center, prospective, randomized controlled clinical trial. After receiving CDT, the major branch of the distal iliac vein was completely patent in 155 patients with lower extremity DVT, and 74 of these patients with iliac vein residual stenosis of >50% were randomly divided into a control group (n = 29) and a test group (n = 45). In the test group, stents were implanted in the iliac vein, whereas no stents were implanted in the control group. We evaluated the clinical indicators, including patency of the deep vein, C in CEAP classification, Venous Clinical Severity Score (VCSS), and Chronic Venous Insufficiency Questionnaire (CIVIQ) Score.

RESULTSAll patients had postoperative follow-up visits for a period of 6-24 months. Venography or color ultrasound was conducted in subjects. There was a significant difference between the patency rate at the last follow-up visit (87.5% vs. 29.6%) and the 1-year patency rate (86.0% vs. 54.8%) between the test and control groups. The change in the C in CEAP classification pre- and post-procedure was significantly different between the test and control groups (1.61 ± 0.21 vs. 0.69 ± 0.23). In addition, at the last follow-up visit, VCSS and CIVIQ Score were both significantly different between the test and control groups (7.57 ± 0.27 vs. 0.69 ± 0.23; 22.67 ± 3.01 vs. 39.34 ± 6.66, respectively).

CONCLUSIONThe stenting of iliac vein obstruction following CDT in lower extremity DVT may increase the patency of the deep vein, and thus provides better efficacy and quality of life.

BACKGROUNDInterventional therapy is widely accepted as the first choice for the treatment of the Budd-Chiari syndrome, but the use of radical correctional therapy should not be discarded. This study describes radical correction by controlling bleeding from distal end of pathological segment of the inferior vena cava (IVC) and discusses potential surgical errors and postoperative complications.

METHODSOf the 216 patients in the study, 78 were treated with simple membranectomy, 64 with dissection of the pathological segment of the IVC and vascular prosthesis or pericardial patch plasty, 60 with resection of the pathological segment of the IVC and orthotopic graft transplantation with vascular prosthesis, and 14 with resection of the occlusive main hepatic vein and its upper IVC, hepatic venous outflow plasty and vascular prosthesis orthotopic graft transplantation from the hepatic venous entrance to the IVC of right atrial ostium.

RESULTSExcept 14 cases who were discharged after hepatic vein outflow plasty, four cases died postoperatively, and 198 patients were discharged without complications. The symptoms of 15 patients were relieved partially and 2 without any change. There were no deaths intraoperatively. Of the 112 cases who were followed up for 72 months, 13 suffered from a relapse.

CONCLUSIONSRadical correction is a beneficial therapy in the treatment of Budd-Chiari syndrome.

BACKGROUNDIliac vein compression syndrome (IVCS), the symptomatic compression of the left common iliac vein between the right common iliac artery and the vertebrae, is not an uncommon condition. The aim of this research was to retrospectively evaluate long-term outcome and the significance of endovascular treatment in patients with left IVCS.

METHODSBetween January 1997 and September 2008, 296 patients received interventional therapy in the left common iliac vein. In the second stage, 170 cases underwent saphenous vein high ligation and stripping. Two hundred and thirty-one cases were followed up over a period of 6 to 120 months (average 46 months) and evaluated for symptom improvement with color ultrasound and ascending venography.

RESULTSThe stenotic or occlusive segments of the left iliac vein were successfully dilated in 285 cases, of whom 272 received stent implantation therapy. Most of the patients achieved satisfactory results on discharge. During the follow-up period, varicose veins were alleviated in 98.7% of the patients, and leg swelling disappeared or was obviously relieved in 84% of cases. About 85% of leg ulcers completely healed. The total patency rate was 91.7% as evaluated with color ultrasound and 91.5% with ascending venography.

CONCLUSIONSEndovascular treatment of IVCS provides effective symptomatic improvement and good long-term patency in most patients.
