Multiple myeloma (MM) is a largely incurable B-cell hematologic malignancy. Although some patients treated with traditional therapies, such as chemotherapy and radiotherapy,can enter a remission,the disease remains incurable. One of the biggest improvements in the treatment of MM is the use of high-dose chemotherapy followed by stem cell transplantation, which have resulted in an improved remission rate, diseasefree survival and overall survival.

Objective To evaluated the effect of Total Glucosides of Paeony (TGP)combined with urokinase for the patients with acute cerebral ischemic stroke.MethodsA total of 152 patients with ACIS were divided into the control group (77 patients) and the observation group (75 patients) by completely randomized grouping method. Patients in the control group were treated with Urokinase by intravenous, and the observation group were treated with TGP combined with Urokinase. All patients were treated with thrombolysis treatment with in the 24 h after the exclusion of cerebral hemorrhage by brain CT and coagulation mechanism disorder. In the following 14 days, they were given the treatment of anti platelet aggregation, lowering blood lipid, trophic nerve and improving circulation. The National Institutes of Health Stroke Scale(NIHSS), the modified Rankin scale(mRS) and the daily life ability index(Barthel) were measured.ResultsThere were 28 (37.3%) patients with the NIHSS scores decreasing 4 points in observation group and 12 (15.6%) in control group after treatment of 7 days,and there was significant difference between two groups (χ2=8.181,P=0.004). There were 68 (90.7%) patients with mRS score less than 4 points in observation group and 51 (15.6%) in control group after treatment of 14 days,and there was significant difference between two groups (χ2=11.945,P=0.001). The NIHSS scores in the observation group was lower than control group (8.3 ± 2.2vs. 9.9 ± 2.5;t=4.192,P<0.05). The mRS score in the observation group was lower than control group (2.3 ± 0.9vs. 2.9 ± 1.1;t=3.684,P<0.01), and the Barthel index in the observation group was higher than the control group (88.7 ± 16.2vs. 77.5 ± 15.2;t=4.401,P<0.01). ConclusionsThe TGP capsules combined with Urokinase intravenous thrombolysis could improve the neurological deficit, and the ability of daily life of ACIS patients.

Objective To investigate the effect of electrovaporization on prostatic tissue structure in vivo. Methods 26 cases of benign prostatic hyperplasia underwent electrovaporization of prostatic tissue,the surface area of the vaporized prostatic tissue and the depth at the central area being observed with light microscope and electron microscope. Results The vaporizing effect on tissue with pure cut current were stronger than that with pure coagulative current, the greater the output power the stronger the vaporizing effect.6 millimeter under the vaporized surface caused by pure coagulative current still revealed some histological alterations of injury,while these histological alterations in pure cut current electrovaporization was less. Conclusions These findings may have implications that in transurethral electrovaporization of prostate,injury to the adjacent or deep tissues should be avoided as much as possible.

0.05).Follow-up coronary angiography was more frequently performed in group A than in group B.Conclusion In patients with acute myocardial infarction treated with primary percutaneous coronary intervention,the transradial approach is a safe and feasible technique.With the higher rate of follow-up angiography,it was found that the incidence of MACE at 1-month follow-up and 6-month follow-up using the transradial approach was similar to transfemoral approach.Therefore,the transradial approach is expected to become the substitute approach for treatment in AMI patients.

Cardio-protective action of synthetic peptide 6A, fibrinogen degradation segment, was observed on the myocardial injury model produced by subcutaneous injection of iso-proterenol (30 mg?kg-1-d-1) into rat. Treatment with peptide 6A (50 ?mol?kg-1? d-1,iv) significantly ameliorated isoproterenol-induced myocardial lesion, inhibited release of myocardial creatine phosphokinase, ?-hydroxybutyratedehydrogenase, lactate dehydrogenase and gluta-mate-oxaloacetate transaminase, lowered plasma fibrinogen content,and markedly prevented myocardial calcium accumulation. The results suggest that peptide 6A could have potential significance for clinical therapy of ischemia heart diseases.

OBJECTIVE:To establish a method for the simultaneous determination of uracil,hypoxanthine,xanthine,uridine and adenosine in Eisenia foetida. METHODS:HPLC was performed on the column of Venusil XBP C18 with mobile phase of 50%methanol-0.01 mol/L potassium dihydrogen phosphate solution(gradient elution)at a flow rate of 1.0 ml/min. The detection wave-length was 254 nm with a column temperature at 30 ℃,and the injection volume was 10 μl. RESULTS:The linear range was 0.05-1.60 μg for uracil(r=0.9991),0.05-1.60 μg for hypoxanthine(r=0.9993),0.002-0.010 μg for xanthine(r=0.9991), 0.0075-0.24 μg for uridine(r=0.9999)and 0.0250-0.80 μg for adenosine(r=0.9990);RSDs of precision,stability and accuracy tests were lower than 3%;recoveries were 98.30%-100.76%(RSD=0.8%,n=9),98.68%-100.96%(RSD=0.8%,n=9), 95.16%-97.67%(RSD=0.9%,n=9),96.15%-99.57%(RSD=1.5%,n=9)and 96.39%-101.93%(RSD=1.8%,n=9),respective-ly. CONCLUSIONS:The method is simple and stable with good reproducibility,and can be used for the simultaneous determina-tion of uracil,hypoxanthine,xanthine,uridine and adenosine in E. foetida.

Objective To explore clinical characteristics of chronic total occlusion(CTO) in population with routine coronary angiography,and to cumulate therapeutic experience.Methods Retrospective analysis was performed on clinical data of 57 cases with CTO selected from 825 patients undergone coronary angiography.Results Among 57 cases,the percentage of male,myocaridial infarction,diabetes mellitus,hyperlipidermia and left ventricular dysfunction was 73.7%,84.2%,22.8%,73.7% and 22.8%,respectively.The types of lesions included single branch(n=11),double branches(n=29) and three branches(n=17).Of 70 branches lesion vessels,44 were TIMI 0 of blood flow classification and 26 were TIMI1.The position of lesions occurred at left anterior descending branch(n=32),left circumflex branch(n=16),right coronary artery(n=22).The occlusion time was less than three months(n=41) and more than three months(n=29).The lengths of lesion was divided into less than 20 mm(n=43) and more than 20 mm(n=27).The shapes of terminal lesion looked like rat-tail(n=42) and blaze knife-edge(n=28).The coronary stents were performed at 57 lesions among 70 branches and the successful rate of operation was 82.9%.Conclusions Timely coronary angiography and selecting suitable treatment on different kinds of lesions for male patients with myocardial infraction,especially complicated with diabetes mellitus,might play important roles in prevention of CTO and in improvement of the successful rate of percutanous coronary intervention for the complex lesion.

Objective To detect the expression of hypoxia inducible factor-lα (HIF-1α) in both mRNA and protein and reactive oxygen species (ROS) levels in human epithelial ovarian cancer,and investigate the abnormal state of oxygen metabolism and their interaction in human epithelial ovarian cancer develoment.Methods The expression of HIF-1α in mRNA and protein in epithelial ovarian cancer were detected by real time reverse transcription-polymerase chain reaction and immunohistochemical Elivision plus two-step method,and the level of ROS was detected by fluorescence microplate reader.Results The relative content of HIF-1α mRNA in the epithelial ovarian cancer group was 4.466±0.754,which was higher than that of the benign control group (6.073±1.053) (t =-7.701,P =0.000).The expression of HIF-1α mRNA was raised gradually in tissues of the benign ovarian tumor,early and advanced stage of epithelial ovarian cancer (t =5.301,P =0.000).The expression of HIF-1α mRNA in the epithelial ovarian cancer had positive correlation with grade and lymph node metastasis (t =3.724,-3.851,P =0.000).The positive expression rate of HIF-1 α protein in epithelial ovarian cancer was 63.49 ％ (40/63),which was higher than that of the benign group (U =433,P =0.005),which had positive correlation with lymph node metastasis and stage (x2 =4.289,12.360; P =0.038,0.000).The expression of ROS in the epithelial ovarian cancer was 110.239±18.414,which was higher than that of the benign group (58.366±20.360) (t =11.068,P =0.000),which had positive correlation with grade,lymph node metastasis and stage (t =-2.055,2.816,-4.138; P =0.044,0.007,0.000).There was a moderate positive correlation between the expression of HIF-1α mRNA and ROS in epithelial ovarian cancer (r =0.572,P =0.000),and that was similar in low differentiation group and advanced group,there was a relatively high positive correlation in lymph node metastasis group (r =0.703,P =0.001),there was a relatively low correlation between HIF-1α mRNA and ROS (r =0.376,P =0.002).Conclusion Hypoxia is the basic characteristic of human epithelial ovarian carcers.This study suggested that HIF-1α is associated with human epithelial overaian cancer prognosis.ROS and HIF-1α might be involved in the genesis of human epithelial ovarian cancer,and the regulation of ROS to HIF-1α may play the important roles in the invasion and metastasis process of human epithelial ovarian cancer.The expression of HIF-1α is regulated by ROS at the transcriptional and protein levels,probably mainly on protein level.

Objective:To explore the relationship among occupational benefits,turnover intention and quality of life in nurses using structural equation model,thus to provide evidence for improving the quality of life.Method:We conduct a survey among 965 nurses using the general information questionnaire,the occupational benefits scale,turnover intention scale (TIS) and the SF-36 scale.Restult:The total score of occupational benefits was (135.79 ± 18.82),the TIS score was (13.48 ±4.11),and the SF-36 score was (532.91 ± 141.75).There was a positive correlation between occupational benefits and the quality of life,and the turnover intention was negatively correlated with the quality of life.Structural equation model analysis showed that the occupational benefits and turnover intention had a direct significant effect on nurses' quality of life;occupational benefits has a direct negative effect on turnover intention,and indirectly effects quality of life of nurse through the mediating effect of turnover intention.Conclusion:The nurses' quality of life needs to be improved,and occupational benefits and turnover intention have significant prediction effect on quality of life.
