Objective To detect the effect of Guided Relaxation Method with Music on pain sensitivity and hemodynamics in acupuncture.Methods 70 volunteers aged 18 to 22, all in good condition, were randomized to study group or control group (each 35).In the control group, volunteers were only treated with acupuncture in a routine way while volunteers in the study group were treated with acupuncture using Guided Relaxation Method with Music .Comparing the change of heart rate and blood pressure before and after the experiment, and the pain sensitivity between these two groups.Results By comparing the two groups, it showed that there were no significant differences in heart rate, diastolic blood pressure and systolic blood pressure level(p>0.05).Numerical rat-ing scale scores in study group was much lower (p<0.001), and systolic blood pressure level after the experiment decreased more significantly than that in the control group (p<0.05).However, no significant differences can be seen in heart rate and diastolic blood pressure level after the experiment (p>0.05).Conclusion Guided Relaxation Method with Music could help to alleviate the feeling of pain, and make acupuncture therapy more acceptable.

ObjectiveTo retrospectively analyze the relationship between clinicopathological,biological characteristics and the outcome of renal cell carcinoma(RCC) and evaluate the risk factors related to metastasis in young patients.MethodsThe data of 83 RCC patients younger than 40-year-old, treated from January 1986 to December 2007 in Tianjin Cancer Hospital,were analyzed retrospectively.The complete follow-up data of the 83 cases were collected.The operative methods included partial and radical surgery.Clinical staging were consistent with the 2004 UICC TNM classification criterion.The histological sections were reviewed.Various biological factors including VEGFR-1, VEGFR-2, VEGFR-3, PDGFR-α, PDGFR-β, c-kit and PCNA were tested by immunohistochemistry staining.The adjuvant radiation therapy, chemotherapy and immunotherapy after operation were carried out on the basis of pathological and biological features.The 83 cases were divided into two groups according to metastasis and non-metastasis status within 5 years.The prognosis related factors including clinical factors, pathological and biological factors were evaluated.Chi-square test was used for the analysis of 5-years metastasis status; and multivariate analysis was carried out using Cox proportional hazards models to assess the independent effect of the metastasis factors (the test standard α = 0.05).ResultsThe 5-year follow-up data showed that the metastasis rate in the 83 cases was 16.87％ (14/83).The Chi-square test results indicated that the patients with clinical stage Ⅲ and grade 3 had the highest metastasis rate (57.14％ and 78.57％respectively,x2 =38.042, x2 = 9.820; Ps ＜ 0.01) .The VEGFR-3 and PCNA positive expression rates were 92.86％ and 85.71％ respectively in metastasis group.The metastatic risk of early stage patients was 3.444 times as much as the advanced stage patients.ConclusionThe young patients with clinical advanced renal cell carcinoma had worse outcome.The stage,grade, VEGFR-3 and PCNA expression were the risk factors correlated with the metastasis risk for young RCC patients.TNM stage was an independent predictive risk factor of metastasis in young patients.

AIM: To investigate the protective effect of calcium antagonists on anoxia/reoxygenation (A/R) injury of cardiomyocytes. METHODS: Primary-cultured cardiomyocytes were divided into four groups, namely A/R, A/R+nifedipine(Nif), A/R+ruthenium red(Ru)+heparin (Hep) and control groups. The following parameters were measured in all groups: intracellular calcium concentration ([Ca 2+ ]i), cardiac cell viability, ATP content, lactate dehydrogenase (LDH) activity in the medium, PKC and MAPK activity and -Leucine(-Leu) incorporation. RESULTS: In comparison with A/R group, A/R+nifedipine(Nif) and A/R+ruthenium red(Ru)+heparin (Hep) groups showed a marked decrease in [Ca 2+ ]i and LDH content, and a significant increase in cell viability ,ATP content, activity of PKC and MAPK and -Leu incorporation(P

Objective To investigate the risk factors,clinical and coronary angiographic characteristics in women less than 50 years with coronary heart disease(CHD).Methods One hundred and twenty-six women less than 50 years were divided into CHD group and non-CHD group according to the result of coronary angiography(CAG).Risk factors,clinical and coronary angiographic characteristics were investigated retrospectively.Results In 6395 cases who were given CAG in the corresponding time period,126(1197%)women were less than 50 years,and 44 cases were confirmed as having CHD by CAG[CHD group,mean age(46.8±3.6)years)].Meanwhile 82 cases were in non-CHD group[mean age(45.4±4.3)years)].The incidence rate of hypertension[77.3%(34/44)vs 26.8%(22/82)],diabetes mellitus[34.1%(15/44)vs 4.9%(4/82)],hyperlipidemia[43.2%(19/44)vs 7.3%(6/82)],family history of CHD[43.2%(19/44)vs 7.3%(6/82)],and risk factors of family history of CHD[52.3%(23/44)vs 12.2%(10/82)]had significant difference between CHD group and non-CHD group(P<0.01).88.6%(39/44)CHD palients were acute coronary syndrome,50.0%(20/44)lesion was one-vessel lesion.Left anterior descending coronary was involved most easily.The degree of calcification was lighter.The type.of lesion was mostly localized and segmented.Conclusions Hypertension,hypedipidemia,diabetes mellitus,family history of CHD,and risk factors of family history of CHD are the major risk faetom in women less than 50 years with CHD. The possibility of CHD is higher when having classical angina and multiple risk faetom.

Objective To evaluate anti-HEV IgG and IgM diagnostic kits with sera from convalescent hepatitis E patients and to establish the quantification method of detecting anti-HEV lgG.Methods Detect 42 convalescent serum samples of over 6 months after onset of hepatitis E patients from Jiangsu province with anti-HEV IgM and IgG diagnostic kits. Select and mix the anti-HEV IgG positive sera which were confirmed by Western blot with ORF2 and ORF3 antigen. The mixed serum was calibrated with a WHO anti-HEV Ig standard. A series quantitative linear standard was made for quantitative detection of anti-HEV IgG in hepatitis E vaccine clinical trials phase Ⅲ. Results The positive rates of the anti-HEV IgG di-agnose kits of G, K, MP, Wantai were 71.4%, 78.6%, 92.9% and 100% respectively. The positive rates of G was lower than that of MP (χ~2 = 5.19, P<0.05) and obviously lower than Wantai (χ~2 = 11.76,P<0.01). The positive rates of K was also obviously lower than that of Wantai (χ~2 =7.96, P <0.01).The positive rates of the anti-HEV IgM diagnose kits of MP, G, X, Wantai, K were 21.4%, 7.1%,21.4%, 64.3%, 78.6% respectively. The positive rate of both K and Wantai were obviously higher than that of MP(χ~2 = 15.75 ,P<0.01 ; X2 = 27.43 ,P< 0.01). With the Western blot confirmation test, 30 and 18 sera were reactive to ORF2 and ORF3 antigen separately. The anti-HEV IgG concentration of HEV-D01 mixed by 13 samples was 57.94 U/ml by the calibration. Prepare seven 1.5-fold dilution series of quantita-tive linear standard for HEV vaccine clinical trials phase Ⅲ, concentration range from 0.077 to 0.877 U/ml. The quantitive values of high, medium and low concentrations quality control samples lay in the range of average ± 2s, and the CV of quantitative values were 16%, 16%, 12% respectively. Conclusion The quality of different anti-HEY IgM and IgG diagnose kits were different. This study had set up a set of anti-HEV IgG linear quantitative standard, which fit for detecting anti-HEV IgG antibodies quantitatively in HEVvaccine clinical trial phase Ⅲ.

Objective To study the association of liver fat content (LFC) with insulin resistance and β cell function. Methods One hundred and nine subjects including 31 cases with impaired glucose regulation (IGR), 31 newly diagnosed type 2 diabetes (NT2DM) and 47 normal controls (NC) with normal metabolic parameters were involved in the study. LFC was measured by 1H magnetic resonance spectroscopy (1H MRS) and the insulin resistance and β cell function were evaluated by oral 75 g glucose tolerance test. Results (1 ) LFCs were3.83% (2.35% ～7.59% ) ,12. 82% (8.10%～21.37%), and 21.99% (11.89%～34.43%), being progressively raised in the respective NC, IGR, NT2DM groups(P<0.01). (2) The subjects were divided into four subgroups according to LFC Quartile: Quartile 1 (LFC<4. 04% ) , Quartile 2(4. 04% ≤LFC<9. 77% ), Quartile 3 (9.77% ≤LFC<20.78% ) ,and Quartile 4( LFC≥20.78% ). Homeostasis model assessment of insulin resistance index (HOMA-IR) values were elevated significantly and progressively starting from Quartile 2(P<0. 01). (3) Insulin from 0 to 30 min ( △I30), the ratio of insulin from 0 to 30 min to glucose from 0 to 30 min ( △I30/ △G30) , C peptide from 0 to 30 min (△CP30) had a trend of increase in Quartile 2,then trended to decrease in Quartile 3. In Quartile 4, △CP30 and △I30/△G30 sharply decreased (P<0.05 or P<0.01). The ratio of C peptide from 0 to 30 min to glucose from 0 to 30 min ( △CP30/△G30) began to decrease from Quartile 3 (P<0. 05). The ratio of area under curve of C peptide to area under curve of glucose (CPAUC/GAUC) was significantly decreased from Quartile 3(P<0.05). From Quartile 3,glucose level became abnormally elevated to impaired fasting glucose and impaired glucose tolerance (P<0.01). (4) LFC was positively correlated with HOMA-IR (rs =0. 618 ,P<0.01), but was negatively correlated with △CP30(rs =-0.282), △CP30/△G30(rs = -0. 404), and CPAUC/GAUC(rs = -0. 308,all P<0.01). (5) Stepwise regression analysis demonstrated that LFC was the strongest predictor of HOMA-IR. Conclusions When LFC accumulated to 4% , insulin resistance occurred and the early phase of insulin secretion was compensatively increased. As the LFC further accumulated to 10% , both the early phase as well as β cell function in whole were deteriorated, and hyperglycemia developed.

To study the hemolytic effect of polyphyllin II (PP II) mediated by anion channel protein and glucose transporter 1 (GLUT1), in order to initially reveal its hemolytic mechanism in vitro. In the experiment, the spectrophotometric method was adopted to detect the hemolysis of PP II in vitro and the effect of anion channel-related solution and blocker, glucose channel-related inhibitor and multi-target drugs dehydroepiandrosterone (DHEA) and diazepam on the hemolysis of PP II. The scanning electron microscope and transmission electron microscope were used to observe the effect of PP II on erythrocyte (RBC) morphology. The results showed that PP II -processed blood cells were severely deformed into spherocytes, acanthocyturia and vesicae. According to the results of the PP II hemolysis experiment in vitro, the anion hypertonic solution LiCl, NaHCO3, Na2SO4 and PBS significantly inhibited the hemolysis induced by PP II (P < 0.05), while blockers NPPB and DIDS remarkably promoted it (P < 0.01). Hyperosmotic sodium chloride, fructose and glucose at specific concentrations notably antagonized the hemolysis induced by PP II (P < 0.05). The glucose channel inhibitor Cytochalasin B and verapamil remarkably antagonized the hemolysis induced by PP II (P < 0.01). The hemolysis induced by PP II could also be antagonized by 1 gmol x L(1) diazepam and 100 μmol x L(-1) DHEA pretreated for 1 min (P < 0.01). In conclusion, the hemolytic mechanism of PP II in vitro may be related to the increase in intracellular osmotic pressure and rupture of erythrocytes by changing the anion channel transport activity, with GLUT1 as the major competitive interaction site.
