Objective To evaluate the role of TCD examination in diagnosis of the early cerebrovascular diseases in aged diabetic patients.Methods 179 cases of aged type Ⅱ diabetic patients were divided into three groups(PDR,BDR and NDB)according to their retinopathy.TCD and retina examination were performed in all patients and the data be analysed. Results (1)The systolic peak flow velocity(Vp) of MCA、ACA、ICA and BA were significant increased in diabetic pa- tients than in normal control group(P

Forty-two patients with type 2 diabetes mellitus (DM) were refered to 3 groups:type 2 DM without diabetic nephropathy (DN),type 2 DM with DN in the initial stage and type 2 DM with DN in the clinical stage.Ten healthy subjects were served as control group.Plasma adrenomedullin (ADM),urinary?_1- microglobulin (MG) and?_2-MG were detected.The results showed that the level of plasma ADM rose gradually with the development of DN and was positively correlated with markers of tubulointerstiial injury such as urinary?_1- MG and?_2-MG (both P

Objective To investigate the effect of intrathecal(IT)different concentrations of ozone(O_3) on pain threshold,motor function and cerebral spinal fluid(CSF)malondialdehyde(MDA)concentration and superoxide dismutase(SOD)activity and determine if ozone is toxic to central nervous system(CNS).Methods Thirty New Zealand white rabbits of both sexes aged 3-5 months,weighing 2.5-3.0 kg were randomly divided in 5 groups(n=6 each):groupⅠcontrol;groupⅡpure O_2;groupⅢO_2-O_3 30;groupⅣO_2-O_3 50 and groupⅤO_2-O_3 80.The animals were anesthetized with intraperitoneal pentobarbital.Cerebello-medullary cistern was punctured for IT administration of O_2 and O_3.In groupⅡ2 ml of pure oxygen(O_2)(for medical use)was injected IT.In groupⅢ,ⅣandⅤ2 ml of ozone(O_3)30,50 and 80 mg?L~(-1) was injected IT respectively.Ozone was manufactured by ozone generator(Ozoneline Co,Italy).Before and one day after IT O_3 paw withdrawal latency to heat(PWHL)and to mechanical stimulation(yon Frey filament)(PWML)were measured and motor function was assessed(1=normal,4=severe motor dysfunction and weakness).CSF was obtained at 1,2,4 h after IT O_3 for determination of MDA concentration and SOD activity.Results IT administration of the 3 concentrations of ozone did not affect pain threshold and motor function,but significantly increased SOD activity.MDA concentration decreased significantly at 4 h after IT O_2 or ozone administration in groupⅡ,ⅢandⅣ,but increased significantly at 1 and 2 h after IT ozone in groupⅤ.SOD/MDA was significantly increased at 1,2 and 4h after IT ozone in groupⅢandⅣ,but decreased at 1 and 2 h after IT ozone in groupⅤ.Conclusion IT ozone is toxic to CNS.

OBJECTIVETo explore the expression of human leucocyte antigen DR (HLA-DR) gene in peripheral blood mononuclear cells (PBMCs) of systemic lupus erythematosus (SLE) patients of various TCM syndrome types in order to seek an objective index for syndrome differentiation of SLE.

METHODSSLE patients were sorted into various syndrome types by TCM syndrome differentiation, i. e. Pi-Shen yang-deficiency type (A), yin-deficiency with internal heat type (B), qi-yin deficiency type (C) and Gan-Shen yin-deficiency type (D). Their peripheral blood sample was collected for detecting HLA-DR positive lymphocytes and monocytes in PBMC using flow cytometry.

RESULTSComparisons among patients of various syndrome type showed that the proportion of HLA-DR positive monocytes and lymphocytes in PBMC in patients of type A was the lowest (P < 0.01); proportion of HLA-DR positive lymphocytes in patients of type B was significantly higher than in those of type C and D (P < 0.01), and that in type D was higher than in type C (P < 0.05); total proportion of HLA-DR positive cells in patients of type A was the lowest, that in type B was higher than that in type C and D (P < 0.01, P < 0.05), while no significant difference was found between the latter two types (P > 0.05).

CONCLUSIONHLA-DR could be taken as an objective index for reference in syndrome differentiation of SLE.

AIMTo establish an HPLC-ELSD method for the quantification of pedunculoside, ziyuglycoside I and rutundic acid, in the leaves of Ilex purpurea Hassk.

METHODSBy optimizing the chromatographic conditions of HPLC and the parameters of ELSD to study the methodology. Column: Allsphere ODS-2 (250 mm x 4.6 mm ID, 5 microns), mobile phase: methanol-water (59:41), flow rate: 1.0 mL.min-1, drift tube temperature: 59 degrees C, gas flow rate: 2.38 L.min-1.

RESULTSThe calibration curves were linear in the range of 2.56-25.60 micrograms for pedunculoside, 1.64-16.40 micrograms for ziyuglycoside I and 3.74-37.40 micrograms for rutundic acid. The average recovery of pedunculoside was 96.3%, RSD 1.59% (n = 5), ziyuglycoside I 97.3%, RSD 3.82% (n = 5), rutundic acid 97.7%, RSD 2.11% (n = 5). All of RSDs of the precision were less than 4% (n = 6), and the reproduciblities less than 5% (n = 6).

CONCLUSIONThe method is simple, accurate, effective and feasible. It can be used for the determination of the contents of pedunculoside, ziyuglycoside I and rutundic acid in leaf of Ilex purpurea Hassk.

One hundred and fifty two actinomycetes were isolated from forty two radiation-polluted soil samples,using six different isolation media. Sixty cultures were chosen for 16S rRNA gene sequence and systematic analysis,which based on their morphology and ARDRA. Results of 16S rRNA gene sequences blasting showed that the strains were assigned to 12 recognized genera of actinomycetes,most of them fall within Streptomyces genus and a great deal of strains belonged to rare actinomycetes,which indicated a rich diversity of actinomycetes in the radiation-polluted soil.

Objective To investigate the expression of immunohistochemistry of gastrin(GAS),somatostatin(SS),proliferating cell nuclear antigen(PCNA) and Fas-ligand(Fas-L) in the sinus ventriculi of children with pediatric gastritis and to explore the significance of their expression in the pathogenesis of pediatric chronic gastritis.Methods Fifty cases of the sinus ventriculi mucosa samples were enrolled in 3 groups:chronic gastritis,helicobacter pylori(Hp) positive(group A,n=20);chronic gastritis,Hp negative(group B,n=19);control group,normal sinus ventriculi mucosa,Hp negative(group C,n=11).Immunohistochemistry En Vision were carried out including GAS,SS,PCNA and Fas-L.Results In the expression of GAS and SS,the values of group A and B were comparatively higher than those of group C,but there was no significant difference among them in statistics.In the expression of PCNA,the value of group A was comparatively higher and that of group B.The value difference between 2 groups was significant(P=0.019);in the expression of Fas-L,no significant difference was found among these 3 groups.Conclusions Expressions of GAS and SS both increase in children with chronic gastritis and maybe the increase of GAS and SS play a role in the pathogenesis of pediatric chronic gastritis;Hp infection promotes the multiplication of the sinus ventriculi membrana mucosa epithelium cell in pediatric chronic gastritis.

OBJECTIVETo explore the action mechanism of Jiedu Quyu Zishen Recipe (JQZR) on the signal transduction of glucocorticoid receptor alpha (GRalpha) in the renal tissue of MRL/lpr mice.

METHODSThirty MRL/lpr mice were randomly divided into three groups, i.e., the model group, the Western medicine group, and the Chinese medicine group, 10 in each. Besides, another 10 Kunming mice was taken as the normal control group. The pathological changes of the renal tissue were observed using HE staining. The expression of GRalpha was analyzed using Real-time PCR and Western blot. The effects of JQZR on the binding power of GRalpha to cyclophilin A were detected using co-immunoprecipitation.

RESULTSThe renal injury degree of MRL/lpr mice in the Western medicine group and the Chinese medicine group was alleviated. Compared with the model group, the relative quantitation of GRalpha mRNA and protein expressions in the renal tissue of mice in the Western medicine group decreased, while they increased in the Chinese medicine group, showing statistical difference (P < 0.01). JQZR could significantly elevate the binding potency of GRalpha to cyclophilin A.

CONCLUSIONUp-regulating the expression of GRalpha and enhancing mutual actions of GRalpha and cyclophilin A was one of JQZR's effects on improving the lesion of the renal tissue.
