Non-vascular interventional diagnostic methods of thyroid nodules include ultrasonography-guided fine-needle aspiration cytology(USgFNAC)and ultrasonography-guided core-needle biopsy(USgCNB).USgFNAC is a practical method used to select and to guide the treatment of various thyroid nodules, however, it is difficult to make a differentiation between benign and malignant lesions simply to rely on the findings of a small number of cells.USgCNB has the advantage of being able to obtain satisfactory specimen enough for making a histological diagnosis, although this procedure is contraindicated in some patients.Non-vascular interventional treatments of thyroid nodules include percutaneous ethanol injection(PEI) and ultrasonography-guided interstitial laser photocoagulation(USgILP).Both PEI and USgILP have fine effect on the benign thyroid nodules.Compared with PEI, laser-induced necrosis can be well controlled, thus, the adverse reactions, such as the formation of fibrosis adjacent to the nodule, vocal cord paralysis, etc.can be avoided.Non-vascular interventional treatments may cause some untoward effects.For the diagnosis and treatment of thyroid nodules, the non-vascular interventional procedure is simple, safe, effective and economic with less complications, therefore, this technique is worth being popularized in clinical practice.

Purpose:To evaluate the accuracy of diagnosing the gastrointestinal vascular malformation and the value of treatment of the hemorrhage of the interventional radiology.Materials and Methods:The superior mesenteric arteriography or/and the inferior mesenteric arteriography or arteriography of coeliac axis were performed by applying Seldinger's techniques in 22 cases with the gastrointestinal bleeding which were suspicous of the gastrointestinal vascular malformation,otherwise were negative or equivocal in di- agnosis by performing with non-interventional study.Results:Focci were detected in 31 arteriographies (22 cases)with the positive gastrointestinal vascular malformation.Operative treatment were performed in 14 of 22 cases,with confimation of the vascular malformation pathologically.Conclusion:The se- lective coeliac arteriography may be a reliably unique method in detection of the gastrointestinal vascular malformation.

Objective To investigate the serum level of free fatty acid (FFA) and explore its relationship with cytokines and atherosclerosis (AS) in chronic kidney disease (CKD).Methods The serum level of FFA was determined with enzymatic colorimetry.IL-1 β, IL-6 and TNFα were determined with ELISA.High-sensitivity C-reactive protein (hsCRP) was measured with immunoturbidimetry.Prevalence of atherosclerosis was detected with carotid ultrasonography.We evaluated the relationship between serum levels of FFA and IL-1β,IL-6, TNFα, hsCRP as well as the renal function in 130 adult patients with CKD, stratified according to the GFR ( based on the National Kidney Foundation/Kidney Dialysis Outcomes Quality Initiatives) and in 58 hemodialytic (HD) patients.The relationship between FFA level and cardiac geometry incidence in CKD patients was analyzed with logistic regression model.Results The serum level of FFA was significantly higher in CKD patients as compared with that in the healthy controls [(492.63 ± 143.59)vs (302.65 ± 142.18) μ mol/L, P ＜ 0.01], even in the early stage of CKD.The level of FFA increased with the progression of renal dysfunction.In the non-dialytic CKD group, the level of FFA was negatively related to GFR and positively related to the proteinuria (P ＜ 0.05), while in the HD group, it was positively correlated with dialysis duration ( P ＜ 0.05 ).The serum levels of FFA were higher in CKD patients with carotid artery atherosclerosis than those in patients without ( P ＜ 0.05 or ＜ 0.01 ).However, in both groups with impairment of renal function, the levels of FFA were positively correlated with hsCRP, IL-1 β, IL-6,TNFα and TG( all P ＜ 0.05 ).A positive correlation between the level of FFA and the clinical manifestations such as carotid intimal medial thickness (IMT) and AS was also found.A negative correlation was found between the level of FFA and the serum level of albumin and GFR( P ＜ 0.05).Conclusion Serum levels of FFA are significantly higher either in non-dialytic CKD or in HD patients and it is related with hsCRP, IL-1 β, IL-6, TNFα as well as carotid artery atherosclerosis, indicating that FFA is an independent risk factor of AS in CKD.

Objective To investigate the effects of levocarnitine combined with urimetazidine on left ventricular remodeling in maintenance hemodialysis(MHD)patients.Methods All of 86 MHD patients and 40 healthy volunteers(health control group)were involved in the study.all of 86 MHD patients were randomly divided into two groups,disease treatment group(46 cases)and disease control group(40 cases),who had undergone hemodialysis for at least 3 months before the study and were in a stable clinical status without signs of infection or disease activity.In disease treatment group,1.0 g of levocarnitine was infused at the end of each dialysis treatment and 20 mg of trimetazidine was taken orally 3 times each day for 6 months,while the parameters for free fatty acid(FFA),free carnitine(FC),inflammation and oxidative stress were studied before and after the treatmenL In disease control group these two drugs were not used.The left ventricular end-diastolic diameter(LVDd),left ventricuhr end-systolic diameter(LVDs),left atrial diameter (LAD),left ventricular posterior wall thickness(LVPWT),interventricular septal thickness(IVST)and left ventricular ejection fraction(LVEF)were detected by ultrasonic cardiography.Results Before treatment,the serum levels of FFA,high-sensitivity C-reactive protein(hs-CRP),intedeukin(IL)-1β,IL-6,tumor necrosis factor(TNF)-αand malondialdehyde(MDA)were higher in disease treatment group and disease control group than those in health control group(P<0.05 or<0.01),while the serum levels of FC,glutathione peroxidase(GSHPx)and superoxide dismutase(SOD)were lower in disease treatment group and disease control group than those in health control group(P<0.05 or<0.01).Compared with those before treatment,the serum levels of FFA,hs-CRP,IL-1β,IL-6,TNF-α,MDA were decreased(P<0.05 or<0.01),FC,GSHPx,SOD were increased(P<0.05 or<0101),the scores of LVDd,LAD,IVST,LVPWT,LVMI were also decreased significantly(P<0.05),while LVEF increased markedly after treatmem in disease treatment group(P<0.05).There were significant differences in all indexes between disease treatment group and disease control group(P<0.05 or<0.01).Conclusion Supplements of levocarnitine combined with trimetazidine in MHD patients appear to be associated with an improvement of left ventricular remodeling.

Obiective To evaluate the current status of studies on interventional recallalization of fallopian tube.Methods According to the standard of evidence-based medicine,literatures were analyzed by two readers in three time periods:1997 to 2000,2001 to 2004 and 2005 t0 2008.Two separate evaluation results were tested by the statistical method Kappa to test its consistency.Scores of clinical controlled trials (CCT)and randomized controlled trials(RCT)were calculated according to Jadad score scale.The accurate criteria of case selection,case exclusion,and effect determination;the method of randomization;the number of samples:the comparability of baseline;the blinded procedure;the therapeutic method;the method of statistical analysis:the follow-up cases; the drop-out cases and the conclusions derivation of RCT and CCT into descriptive analysis were evaluated Results One hundred and fifty seven therapeutic articles were searched and 30 RCT and CCT articles(25 RCT and 5 CCT)were analyzed.The Kappa value was 0.85 and P＜0.05 indicating that the evaluation was in good consistency.2,15 and 8 RCT received 0 point,1 point and 2 points respectively in Jadad score scale.RCT and CCT contained 9 articles(30.0%)fulfilled the accurate criteria of case selection and exclusion:12 articles(40.0%)met the accurate criteria of effect determination:4 articles(13.3%)utilized the definite method of randomization;27 articles (90.0%)had the number of sample beyond 60;14 articles(46.7%)met the baseline comparability;only 1 article(3.3%)used the single-blinded method,17 articles(56.7%)utilized the method of statistical analysis;13(43.3%)mentioned follow-up in articles;4(13.3%)mentioned drop-out cases in the articles and 14(46.7%)articles had the conclusions derived by considering the statistical significance and clinical significance.Conclusion The quality of studies on interventional recanalization of fallopian tube is poor and could not meet the standard of evidence-based medicine.

Objective To study the non-iridoid constituents from the roots of Gentiana straminea.Methods The compounds were repeatedly separated and purified on column chromatography of silica gel,Sephadex LH-20,and ODS,and their structures were identified on the basis of spectral and chemical methods.Results Twelve compounds were isolated from 70% ethanol extract of G.straminea and were identified as(-)-syringaresinol-4,4′-bis-?-O-D-glucopyranoside(1),gentiaphyllide-D(2),erythrecentaurin(3),macrophyiioside D(4),gentiaphyllide-E(5),roburic acid(6),uvaol(7),?-sitosterol(8),daucosterol(9),gentianose(10),?-glucose(11),and ?-glucose(12),respectively.Conclusion Compounds 1-6 and 10 are isolated from this plant for the first time.

Objective:To investigate the relationship between levels of plasma thrombopoietin(TPO) and thrombocytopenia.Methods:Sixty-eight thrombocytopenia with different causes were injected with rhIL-11 domestically made, by 25 ?g/(kg?d) for 10 days continuously. The plasma TPO levels were determined by quantitative sandwich enzyme immunoassay technique in thrombocytopenic patients between before and after treatment.Results:(1)The serum TPO controls of patients with thrombocytopenia after acute leukemia(AL) chemotherapy were lower than normal controls. The plasma TPO levels in aplastic anemia(AA) and myelodysplastic syndrome(MDS) patients were all elevated compared to those in normal controls.The serum TPO levels in patients with idiopathic thrombocytopenic purpura(ITP) and liver cirrhosis had no difference with the normals. Bone marrow megakaryocytes(MK) count in after chemotherapy AL and AA patients were lower than those with normal serum TPO levels controls. (2)In all above patients used interleukin-11(rhIL-11), their TPO levels were close to normal in efficiency patients. On the contrary, their TPO did not change dramatic. Those react to rhIL-11, their TPO levels were inversely correlated with platelet count.Conclusion:Testing serum TPO levels would be helpful for distinguish the thrombocytopenia with different causes, and provides theorical support to patients to use rhIL-11 reasonably.
