Objective To evaluate the efficacy and safety of transarterial chemoembolization (TACE)combined with sonographically guided percutaneous microwave coagulation therapy(PMCT)for hepatic carcinoma with diameter＞5.0 cm.Methods We retrospectively reviewed 68 cases of hepatic carcinoma with diameter＞5.0 cm under treatment of TACE combined with PMCT.CT,USG and correlated laboratory tests of hepatic carcinoma were carried out.Results Among 68 cases,complete ablation were 5 cases(5/68),tumor ablation area more than 50% or tumor shrinkage less than 30% were 59 cases(59/ 68),tumor ablation area less than 50% or tumor shrinkage more than 30% were 6 cases(6/68).Forty five cases with high AFP descended more than 50% after the procedure in 42 eases(93.33%).Thirty seven cases and 29 cases with increase of CEA and CA19-9 decreased to 28(75.97%)and 23(93.10%)cases with corresponding index decreasing more than 50% respectively.Survival time reached 4-6 months in 3 cases, more than 6 months for 31 cases,more than 12 months of 34 cases.Two cases among them showed no recurrence up to now after stoppage of treatment for 24 months and finally no correlative mortality occurred. Conclusion TACE combined with sonographically guided PMCT for hepatic carcinoma with diameter more than 5 cm is safe and effective.

Objective:To investigate association of the new polymorphism G352A in the dopaminetransporter gene(DAT1)exon 15 with attention deficit hyperactivity disorder(ADHD)in Han Chinesechildren.Methods:The new mutant polymorphism G352A in the dopamine transporter gene(DAT1)ex-on 15 was found by the fluorescently-labeled dye-terminators assay.The study samples were comprised of337 ADHD children,207 unrelated controls and 201 integrated ADHD trios(included proband and bio-logical parents).Associations of polymorphisms with ADHD and its subtypes were examined by:(i)comparing cases and controls;and(ii)using family-based association study in transmission-disequilibri-um test(TDT).Results:The allele frequencies at the DAT1 G352A locus in the control samples were79.5% for 352G and 20.5% for 352A respectively.Association studies revealed no association betweenG352A in exon 15 of DAT1 and ADHD.But after a stratification by gender,there was possible associationbetween G352A and ADHD girls:the 352G allele had a tendency to be preferentially transmitted toADHD girls.Conclusion:There is no association between G352A,the new polymorphism,in exon 15 ofDAT1 and ADHD.The 352G allele has a tendency to be preferentially transmitted to ADHD girls,but thefindings require replication before drawing a definitive conclusion.

OBJECTIVETo investigate the effects of carbaryl on serum steroid hormone and function of antioxidant system in female Sprague Dawley rats.

METHODSCarbaryl was administrated to the adult female rats at doses of 0, 1.028, 5.140 and 25.704 mg x kg(-1) x d(-1) for 30 d. Vaginal smears of rats were taken to determine estrous cycle. Serum 17beta-estradiol (E(2)) and progesterone (P(4)) concentrations were measured by radioimmunoassay. The activities of superoxide dismutase (SOD) and glutathione-s-transferase (GST), and the levels of malondialdehyde (MDA) and glutathione (GSH) were measured by spectrophotometry.

RESULTSThe number of estrous cycle in exposed groups were obviously lower than in control group (P < 0.05, P < 0.01). Body weight gain in high dose group (25.704 mg x kg(-1) x d(-1)) was significantly lower than that in control. Meanwhile, the organ coefficient of ovary and uterus declined in a dose-dependent manner. Serum E(2) level [(19.93 +/- 2.21) nmol/L] in 25.704 mg group was lower than in control group [(28.76 +/- 6.12) nmol/L, P < 0.05], and P(4) level (1.21 +/- 0.40) nmol/L in 1.028 mg group was higher than that in control group [(0.63 +/- 0.39) nmol/L, P < 0.05]. The activity of SOD first reduced then rose in ovary, and first rose then reduced in serum. The contents of MDA increased in ovary, while decreased in the serum. GSH contents and GST activity increased in ovary, while in serum GSH contents decreased and GST activity first increased then decreased.

CONCLUSIONCarbaryl could disrupt estrous cycle and affect serum steroid hormone, and the function of antioxidant system in female SD rats.

BackgroundDiabetic retinopathy (DR) is the result of the cytokine network disorders,the imbalance of angiogenic factor and vascular inhibitory factor is the start factor.ObjectiveTo analyze the levels of CXC chemotatic factors of type 2 diabetes mellitus patients,evaluate the clinical application value of them in different clinical types of DR using receiver operating characteristic (ROC)analysis and to approach the new way of individualized treatment.Methods This was a prospective research.The gold standard was ophthalmolscope and fundus fluorescein angiography.The levels of CXC chemotatic factors and multiplicaiton factors were measured in 96 cases with type 2 diabetes mellitus (66 cases with retinopathy and 30 cases without retinopathy as control).The assessment tasks were performed for these index and courses of DR with ROC curve.Results The expression of age,course of disease has significant difference in different courses of DR ( F =8.507,P =0.001 ; F =28.143,P =0.000).Compared with the control group,the expression of growth-related oncogene-α ( GROα ) ( t =- 2.172,P =0.035,AUC =0.625 ),whole blood viscosity 200 ( t =- 3.724,P =0.001,AUC =0.904 ) and neutrophilic leukocyte (t=-2.562,P =0.013,AUC =0.577 ) has significant difference in the group of mild NPDR.Compared with the control group,the expression of interferon-γ-inducible protein 10 ( IP-10 ) ( t =-3.591,P =0.001,AUC =0.592 ),platelet derivation growth factor-BB ( PDGF-BB ) ( t =- 3.233,P =0.003,AUC =0.735 ),vascular endothelial growth factor(VEGF) ( t =- 3.617,P =0.001,AUC =0.776 ),C peptide ( t =- 3.366,P =0.002,AUC =0.962 ),leukocyte ( t=-3.201,P =0.003,AUC =0.852) and neutrophilic leukocyte(t =-4.201,P=0.000,AUC =0.852) has significant difference in the group of moderate and severe NPDR.ConclusionsCXC chemotatic factors may act as reactivator in the pathogenesis of DR,GROα and IP-10 may be useful for clinical monitoring of the severity of DR,and evaluating the imbalance state of chemotatic factors maybe a new approach to clinical monitoring and prognosis of DR.

Objective: To analyze the relationship between thrombin activatable fibrinolysis inhibitor ( TAFI ) and coronary heart disease ( CHD ), and to provide evidence for the prevention of CHD. Methods: The patients with CHD in Fushun Central Hospital in Liaoning Province were selected as the case group, the patients without CHD in the same hospital and period were selected as the control group. The demographic information and clinical examination results ( serum TAFI, lipid, glucose, etc. ) were collected to analyze the association between TAFI and CHD by logistic regression models.The multivariate logistic regression analysis was used to explore the relationship between TAFI and CHD. Results: There were 222 cases, including 100 cases of stable angina, 44 cases of unstable angina and 78 cases of acute myocardial infarction, and 222 controls. The median ages of cases and controls were 62 and 57 years old. The results of multivariate logistic regression analysis showed that serum TAFI>22.88 μg/mL ( P75 of controls ) was associated with the risk of CHD ( OR=1.619, 95%CI: 1.011-2.593 ), unstable angina ( OR=2.917, 95%CI: 1.433-5.939 ) and acute myocardial infarction ( OR=2.626, 95%CI: 1.007-6.847 ). Conclusion The high level of TAFI is related to CHD, unstable angina and acute myocardial infarction.

OBJECTIVETo optimize a pretreatment method of urine proteomics in children with primary nephrotic syndrome.

METHODSUrine from children with primary nephrotic syndrome was treated in different pH and isolated by cold acetone precipitation for different durations. Then the amounts and kinds of proteins were compared by quantify, SDS-polyacrylamide gel electrophoresis (SDS-PAGE) and two-dimensional electrophoresis (2-DE) in order to optimize a way to deal with urine protein.

RESULTSMost proteins were obtained at pH 2.7. The amounts of protein precipitated by acetone for 0.5 hr was obviously less than those precipitated for 1 and 2 hrs (P<0.05), while there was no significant difference between the amount of protein precipitated for 1 and for 2 hrs. Protein precipitated by cold acetone for 1 hr at pH 2.7 was selected as the best pretreatment method. Satisfactory 2-DE maps can be acquired.

CONCLUSIONSUrine protein can be best obtained at pH 2.7 and precipitated by cold acetone for 1 hr.

OBJECTIVETo observe the effects of Ganoderma lucidum spores on Cytochrome C (Cyt-C) and mitochondrial calcium in the testis of NIDDM rats.

METHODSFifty male Wistar rats were divided randomly into three groups: model, ganoderma and normal control, the first two groups injected with 2% STZ through vena caudalis, and the last one with half-and-half sodium citrate/citrate buffer solution. Two weeks after normal diet, glucose tolerance tests were performed and the rats with abnormal glucose tolerance from the model and ganoderma groups received high-fat and high-carbohydrate food, the ganoderma group given Ganoderma lucidum spores (250mg/[ kg x d] ) in addition, both for 10 weeks. Glucose tolerance tests were repeated 1 day before the end of the experiment and the rats were castrated and relevant indexes measured.

RESULTSThe NIDDM model was successfully constructed. In the model group, the levels of mitochondrial Cyt-C and mitochondrial calcium were significantly lower (P <0. 05) while that of the plasma Cyt-C was significantly higher than in the ganoderma and the control groups.

CONCLUSIONCyt-C and calcium ion are involved in the damage of the testis. Ganoderma lucidum spores can protect the testis of NIDDM rats.
