Objective To explore the relationship uPAR in tissue and plasma of patients with cervical carcinoma and its clinical pathophysiological characteristics. Methods The preoperative plasma cancer tissue and its adjacent tissue in 42 cases of patient with ⅠB～ⅡA cervical carcinoma and the preoperative plasma and postoperative cervical tissue in 30 cases of patient with hysteromyoma were collected. Their uPAR were detected by ELISA. Results uPAR in the plasma of patients with cervical carcinoma was significantly higher than those in healthy controls and in patients with hysteromyoma. It was related to tumor invasive depth and lymph node metastasis and not related to tumor differentiation, uPAR in cancer tissue of patients with cervical carcinoma was significantly higher than those in normal cervical tissue. It was related to tumor differentiation and not to tumor invasive depth and lymph node metastasis. Conclusion uPAR in the plasma of patients with cervical carcinoma is related to invasion and metastasis, uPAR in the tissue is related to tumor differentiation.

There are many progresses in the therapy of MM with ASCT. ASCT improves the ratio of CR,EFS and OS,compared with conventional chemotherapy.Myeloma patients with renal failure or old age also can be candidate for ASCT.Tandem autologous transplantation improves the ratio of CR. Its impact to long-term EFS and OS still need to be judged.To improve conditional project,to choose suitable time,and- toselect consolidation schedule can boost therapeutic effect.

Objective To analyze the correlation between the levels of urinary ptasminogen activator receptor (uPAR) and the clinicopathological characteristics of patients with cervical carcinoma and it's clinical significance. Methods SABC immunohistochemistry was employed to detect the expression of uPAR in 50 cases of cervical carcinoma tissue and 50 cases of normal cervical tissue. ELISA method was used to determine the serum uPAR levels for the patients with cervical carcinoma. Results There was no expressionfor uPAR in normal tissues, The positive expression rate of uPAR was 66 % (33/50). The uPAR level of cervix cancer tissues [(70.92±28.55) ng/100 mg protein]was significantly higher than those in normal tissues [(11.01±5.40) ng/100 mg protein], (P ＜0.001). and uPAR levels were closely related to clinical stages,lymphatic metastasis and differentiation degree (P ＜0.05), but not related to deep myometrial invasion and vascular embolization (P ＞0.05) (however, they were not related to patient's age, tumor growth type and the size of tumor. Significant difference of uPAR level was observed between the patients with cervical carcinoma [(2.38±0.29) ng/ml]and in healthy controls [(0.50±0.16) ng/ml](P ＜0.001). Single factor analysis indicated that, before the treatment, the serum uPAR levels were closely related to clinical stages, lymphatic metastasis, vascular embolization, and deep myometrial invasion (P ＜0.05-P ＜0.01). However, they were not related to differentiation degree (P ＞0.05). Multifactor regression analysis showed that the pretreatment serum uPAR levels of patients were related to clinical stages (P =0.000), cavum pelvis lymphatic metastasis (P =0.000) and deep myometrial invasion. Patients with cervical carcinoma showed a dramatic drop in serum uPAR levels after treatment, which were significantly different compared to their pretreatment uPAR levels (P ＜0.001). Linear correlation analysis showed that there was a positive correlation between serum and tissue uPAR levels, (r =0.801, P ＜0.001). Conclusion There were high expression of uPAR in serum and tissues with cervical carcinoma. Pretreatment serum uPAR levels were closely related to patients' clinical stages,cavum pelvis lymphatic metastasis and deep myometrial invasion, serum uPAR levels may be an important tmnor marker for the diagnosis, detection, prognosis of cervical carcinoma.

Aim To investigate the effect of Ginsen-oside Rh2 on apoptosis in human colorectal cancer cell SW480,and to explore the possible mechanism of it. Methods The proliferation activity of SW480 treated with Ginsenoside Rh2 was measured CCK-8 assay.Ap-optosis rates were evaluated by FCM.Hoechst 33258 staining was used to observe cell nucleus morphologi-cal;change SW480 cells were treated with Ginsenoside Rh2,and the protein expressions of Bcl-2,Bax,p53, cleaved caspase-3 ,PI3 K,AKT,P-AKT,GSK-3β,P-GSK-3βwere detected by Western blot;SW480 cells were treated with LY294002,Rh2,LY294002+Rh2, the expressions of PI3 K,AKT,P-AKT,GSK-3β,P-GSK-3βwere detected by Western blot.Results The proliferation of SW480 cells was significantly inhibited by Ginsenoside Rh2 in dose-dependent and time-de-pendent manner.FCM showed the inducing apoptosis effect of Ginsenoside Rh2 was significantly different from that of control group.Hoechst 33258 staining in-dicated clearly cell apoptosis in Ginsenoside Rh2 treat-ment groups.Western blot showed Ginsenoside Rh2 decreased expression of Bcl-2,increased expression of Bax,p53 and cleaved caspase-3,PI3K/AKT/GSK-3βpathway proteins PI3 K,P-AKT,P-GSK-3βdecreased obviously,AKT and GSK-3βwere not changed signifi-cantly in SW480.SW480 cells were separately treated with LY294002,Rh2,LY294002 +Rh2,there were no significant difference in AKT and GSK-3βprotein a-mong all groups,and the expression of PI3 K,P-AKT, P-GSK-3βdecreased more obviously in LY294002 +Rh2 group compared with LY294002 and Rh2 alone. Conclusion Rh2 induces colorectal cancer cell apop-tosis through PI3 K/AKT/GSK-3βpathway,which ac-tivates p53 and cleaved caspase-3,and destroys the balance of Bcl-2/Bax.

Aim To observe the protective effect of quercetin on rat cardiomyocyte apoptosis induced by adriamycin and explore its possible mechanism.Methods Cultured neonatal rat cardiomyocytes were randomly divided into six groups:normal control group, adriamycin group,quercetin control group, adriamycin+quercetin(25,50,100 ?mol?L-1)groups. The activity of LDH was detected by chromatometry, the cardiomyocyte viability was measured by MTT, the ultrastructure of cardiomyocyte was observed by electron microscope, the expression of protein Bcl-2 and Bax was analyzed by immunocytochemical, and the mRNA and protein of caspase-3 were detected by RT-PCR and Western blot respectively.Results Compared with the control group, the activity of LDH was increased but the viability of cardiomyocyte was decreased; the expression of Bax and caspase-3 was up-regulated while Bcl-2 was down-regulated in ADR group.Compared with ADR group, the above changes were lightened in adriamycin+quercetin groups. But the quercetin control group, in which cultured myocardial cells only exposed to quercetin without ADR, had no obvious changes.Conclusions Quercetin significantly inhibits the apoptosis induced by ADR in the cultured myocardial cells. Its mechanism is involved in the apoptosis-related pathways, including caspase-3, Bax and Bcl-2.

Objective Both right and left ventricular function should be taken into account in the assessment of anthracycline (ATC)-induced cardiotoxicity.The aim of this study was to assess the subclinical dysfunction of right cardiac system in patients with newly diagnosed lymphoma who received ATC treatment by echocardiography.Methods A total of 74 patients with lymphoma who received ATC treatment were enrolled.Each patient underwent transthoracic echocardiographic examination before chemotherapy as well as after two,four and six cycles of ATC remedy.Right atrial (RA) and right ventricular (RV) end-diastolic area (EDA) and end-systolic area (ESA) were calculated.RV end-diastolic volume (EDV) and end-systolic volume (ESV),as well as RV ejection fraction (EF) were measured simultaneously.Tissue Doppler imaging (TDI) measurements of systolic and early or late diastolic myocardial velocities of RV free wall at tricuspid annuals were also analyzed.Two-dimensional speckle tracking echocardiography (2DSTE) was conducted to evaluate RV free wall strain along with strain rate.Results None of the echocardiographic parameters showed significant alteration after two and four cycles of chemotherapy compared with those at baseline (P＞0.05).At the end of the therapy (i.e.after six cycles of ATC treatment),there was still no statistical difference on TDI data aswell as 2DSTE measurements (P＞0.05).An unexpected finding was that the RAEDA((6.6±1.9) cm2 vs (7.7±2.4) cm2) and RAESA ((8.8±2.5) cm2 vs (10.8±2.8) cm2) revealed obvious dilatation after six cures of the regimen compared with those at baseline (P＜0.01).Similar morphologic characteristics displayed on the RVEDA ((14.1 ±3.4) cm2 vs (16.2±3.7) cm2) and RVESA ((7.9±1.9) cm2 vs (9.0±2.2) cm2) (P＜0.01)simultaneously.Furthermore,RVEDV ((29.8±10.5) ml vs (37.0±12.7) ml) and RVESV ((12.7±4.4) ml vs (15.0±5.2) ml),as well as RVEF ((59.4±5.8)％ vs (56.4±5.8)％),in patients with lymphoma presented statistically significant difference between basic state and the level after six cycles of chemotherapy (P＜0.01).Meanwhile,no marked change was detected on left ventricular ejection fraction(LVEF) throughout the follow-up period (P＞0.05).Conclusions Echocardiography can be used easily and noninvasively to assess right cardiac system subclinical dysfunction.ATC-induced cardiotoxicity of right cardiac system is firstly manifested as morphological changes than the measurements with novel echocardiographic techniques.In addition,RVEF expresses as a valuable parameter for assessing subtle RV impaired performance in patients with lymphoma received ATC therapy.

Objective To evaluate the subclinical dysfunction of left ventricle (LV) induced by anthracycline(ATC) in patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL) by two-dimensional speckle tracking echocardiography (2DSTE) as well as real-time three-dimensional echocardiography (RT3DE).Methods Traditional echocardiography images and RT3DE images were acquired from 59 patients with DLBCL before,after the completion of two cures(100 mg∕m 2)and four cures of the regimen(200 mg∕m 2).LV global longitudinal strain(GLS),global circumferential strain(GCS),LV apical rotation and basal rotation,LV end-diastolic volume (EDV),end-systolic volume (ESV),stroke volume(SV) and ejection fraction(EF)were calculated simultaneously.Results Compared with baseline, LV apical rotation and basal rotation reduced significantly after two cures and four cures of therapy [LV apical rotation:(5.34±1 .80)°vs (3.80±1 .45)°vs (2.96±1 .1 8)°;LV basal rotation:(-3.32±1 .14)°vs (-2.65±1 .12)°vs (-2.56±1 .19)°;both P <0.01].LV GLS and GCS decreased significantly till four cures of treatment compared with those at baseline[GLS:(-21 .62±2.5 1)% vs(-20.1 7±2.74)%;GCS:(-26.34±4.76)% vs (-23.27 ±4.73)%;both P <0.01].The alternation on EDV,ESV,SV and EF manifested no visible degradation during the whole procedure (P > 0.05 for all). Conclusions Cardiotoxicity during the early phase of anthracycline treatment can be detected via 2DSTE prior to the traditional echocardiographic expression of ventricular systolic function.The left ventricular rotation index seems to be more sensitive than strain parameters for the estimation of early cardiac injury in patients with ATC chemotherapy.There is no safe dose for anthracycline in all patients with DLBCL treated with anthracycline even at lower doses.

Objective To quantitatively analyze total hepatitis B virus (HBV) DNA (HBV tDNA),covalently closed circular DNA (cccDNA) and HBsAg in patients with chronic hepatitis B (CHB),HBV-related liver cirrhosis (LC) and hepatocellular carcinoma (HCC),and to analyze the characteristics.Methods HBV tDNA and HBV cccDNA in the serum and liver biopsy samples were measured in 21 CHB,23 LC and 25 HCC patients by real-time polymerase chain reaction (PCR) assay. HBsAg titer was measured by chemiluminescence. Normally distributed variables among multiple groups were analyzed by ANOVA and t-test.Correlation between two variables was tested using Pearson correlation analysis.Skewed distribution was tested using Rank sum test.Results In CHB,LC and HCC patients,the serum HBV tDNA levels were (5.38±2.08),(4.96± 1.65) and (4.18 ± 0.91) lg copy/mL,respectively; the intrahepatic HBV tDNA levels in three groups were (7.18±1.91),(6.51±1.87) and (5.87± 1.47) lg copy/ug,respectively; the intrahepatic HBV cccDNA levels were (3.53±2.03),(2.63±2.13) and (0.58± 1.40) lg copy/μg,respectively; the serum HBsAg levels were (3.30±0.65),(3.12±0.52) and (2.60± 1.03) lg IU/mL,respectively.In CHB patients,the serum HBV tDNA,intrahepatic HBV tDNA,HBV cccDNA and HBsAg levels were all significantly higher than those of HCC patients (t=2.446,P=0.013; t=2.562,P=0.014;t=5.799,P＜0.01 ; t=2.709,P=0.003,respectively).However,only intrahepatic HBV cccDNA and HBsAg levels were statistically different between LC and HCC patients (t=-3.894,P＜0.01;t=-2.237,P=0.023,respectively).HBV cccDNA was all negative in the serum of 69 patients.The serum HBsAg level was positively correlated with serum HBV tDNA (r=0.290,P=0.016),intrahepatic HBV tDNA (r=0.372,P =0.002) and intrahepatic HBV cccDNA (r=0.378,P=0.001).Conclusions The levels of HBV tDNA,HBV cccDNA and HBsAg decrease gradually with the disease progression.The serum HBsAg level is positively correlated with serum HBV tDNA,intrahepatic HBV tDNA and intrahepatic HBV cccDNA.
