Objective To investigate the effects and safety of sequential treatments with methotrexate and mifepristone for ectopic pregnancy with fetal cardiac activity.Methods 4 cases of ectopic pregnancy with fetal car- diac activity in our hospital were given by sequential therapy with methotrexate and mifepristone.Serum?-HCG,liv- er function and renal function,blood routine and gastrointestinal response were observed.Results 4 cases of ectopic pregnancy with fetal cardiac activity with 1～4 periods of sequential treatments were cured.Except light gastroin- testinal response,and one had slight rise of serum ALT level and AST level,no one had rnyelosuppression and heavy hepatic injury.Conclusion The sequential therapy with methotrexate and mifepristone is an effective and safe method for the treatment to ectopic pregnancy with fetal cardiac activity.

Objective： This study was designed to observe the efficacy and side effects of autologous hematopoietic stem cell transplantation (AHSCT) in the treatment of hematological malignancies and solid tumors. Methods： In the 7 patients, two received autologous bone marrow transplantation (ABMT) and five received autologous peripheral blood stem cell transplantation (APBSCT). The conditioning regimen consisted of VCCA (Vincristine, Me-CCNU, Ara-C, CTX) and TLI(total lymph irradiation) for malignant lymphoma, VCCED (VCR, Me-CCNU, CTX, Vp-16, DNR) and TBI for acute myeloid leukemia-M4, VCCME (VCR, Me-CCNU, CTX, Mitoxantron,Vp-16) for breast cancer. All harvests of stem cells were stored at 4℃ except one at -80℃ ,than transfused back to the patients within 72 hours without purgation. Results： The number of mononuclear cells and CD34＋ cells in harvest in APBSCT patients was (7.45± 5.89)× 108/kg and (18.62± 4.74)× 106/kg,respectively. The patients' granulocyte count reached ≥ 0.5× 109/L on day＋ 9.6 and＋ 11, platelet count reached ≥ 50× 109/L on day ＋ 12.6 and＋ 21.5 and reticulocyte reached ≥ 0.5％ on day＋ 11.2 and＋ 16.5,respectively,after APBSCT and ABMT. The side effects were mainly the gastrointestinal reactions. Up to now, no relapse were seen but four women had developed secondary amenorrhea after AHSCT. Conclusion： AHSCT is an efficient way for malignant tumors and there were earlier hematopoietic reconstitution and fewer side effects in patient with APBSCT than with ABMT. The impairment of gonad by conditioning may affect the quality of life.

Objective To estimate the value of computed tomography perfusion for clinical stage and approach the correlation of perfusion parameters and Cyfra21-1.Methods 63 patients with head and neck squamous carcinoma were confirmed by pathology and follow up underwent CT perfusion,which were divided into three groups by international clinical staging criteria(stageⅠ,stageⅡand stageⅢ-Ⅳ).BF,BV,MTT,TTP and Cyfra21-1 were recorded and compared with correlation in different clinical staging.Results There was no significant difference of Cyfra21-1 between stageⅠand stageⅡ(Z =1.439,P =0.1 62).There was significant differ-ence of Cyfra21-1 between stageⅠand stageⅢ-Ⅳ(Z =3.356,P =0.000),stageⅡand stageⅢ-Ⅳ(Z =4.959,P =0.000).There was significant difference of BF and BV between stageⅠand stageⅡ,stageⅠand stageⅢ-Ⅳ(P <0.05),of MTT and TTP between stageⅠand stageⅢ-Ⅳ,stageⅡand stageⅢ-Ⅳ(P <0.05).There was no significant difference of BF and BV between stageⅡand stageⅢ-Ⅳ(P >0.05),of MTT and TTP between stageⅠand stageⅡ(P >0.05).Cyfra21-1 and perfusion parameters in all groups have relationship(r=0.76,0.76,-0.82,-0.82,P <0.05).Conclusion The statistically significant of positive correlation be-tween Cyfra21-1 and perfusion parameters in head and neck squamous carcinoma suggests that CT perfusion could play a complemen-tary role in clinical assessment.

Objective To detect EIA factor expression in human rectal cancer and normal tissue and to determine whether it is correlated with invasion and metastasis of human rectal cancer. Methods Real- time RT-PCR was used to detect E1AF expression in matched rectal cancers and normal tissues from g6 in- patients.Results Among the 86 rectal cancer samples tested,55 cases E1AF mRNA overexpression was ob- served. The mRNA expression of E1AF in the sample group was remarkably different from that in the control group.In carcinomas,E1AF mRNA expression correlated significantly with histological type,depth of inva- sion,lymph node and distant metastasis and advanced Duke stage.Conclusion E1AF is correlated signifi- cantly with invasion and metastasis of human rectal cancer and may be an important factor in the invasion and metastasis.

Objective To understand the current situation of knowledge on healthy life style among researchers.Data on the knowledge of healthy life style including healthy behavior,general status on health,physical activity and the use of sports facilities were gathered.In 2006,same questionnaire was used to compare with the previous data.Results The percentage of overall knowledge on health among permanent percentage of people who were aware of knowledge on"no-smoking"."intake less salt","maintaining healthy diet program"and"insisting on exercise"were 72.97%,93.11%,86.58% and 87.25% respectively in 2006,higher than 67.38%,89.74%,82.12% and 82.78% during the baseline(P＜0.01)study in the previous years.The percentage of correct answer about the healthy life style as diet and prevention of common diseases was higher among the permanent residents than those of temporary residents in 2006(P＜0.05).The sources of health-related knowledge were mainly from media,newspapers and through health education programs carried out in the community.Conclusion The Beijing municipal government and the community residential committees attached great importance to providing knowledge on

ObjectiveTo investigate the influence of recombinant thioredoxin (TRX)on apoptosis of myocardium cell in viral myocarditis of mice.MethodsTwenty-four Balb/c mice,weighting 12 - 14 g,were randomly divided into 3 groups:the control group,the virus group and the protective group,8 mice in each group.The virus group and the protective group were injected with 0.1 ml 100TCID50 Coxackie virus B3 (CVB3)intraperitoneally,and the control group was injected equal volume of saline.Therewithal the protective group was injected with TRX(2 mg/kg) by tail vein,and the virus group was injected saline the same way.After 14 days all mice were killed and hearts were taken.Changes of myocardial histopathology was observed with optical microscope,cell apoptosis was checked by TUNEL technique,and the expression of apoptosis-related proteins (Bcl-2,caspase-3)in infiltrated cell of myocardium was determined by immunohistochemistry.Results(①)Lymphocyte infiltration and necrosis were observed in survivals of the virus group,sporadic coagulation necrosis and ballooning degeneration of cells were observed in the protective group,however no myocardial lesion was found in the control group.(②)TUNEL technique showed that the positive ratio of apoptosis in the virus group and the protective group[(90.23 ± 3.63)％,(20.02 ± 2.41)％] was significantly higher than that of the control group(0.00 ± 0.00,all P ＜ 0.05),the positive ratio of apoptosis in the protective group was significantly lower than that of the virus group (P ＜ 0.05 ).(③)Immunohistochemistry showed that the expression of protein Bcl-2(+,++,+++) in the virus group and the protective group was significantly higher than that of the control group (all P ＜ 0.05).The expression of protein Bcl-2 in the protective group was significantly higher than that of the virus group(P ＜ 0.05).The expression of caspase-3 (+,++) was significantly higher in the virus group and the protective group than the control group (all P ＜ 0.05).Compared with the virus group,the expression of caspase-3 in the protective group was significantly lower(P ＜ 0.05).ConclusionTRX could inhibit cardiomyocyte apoptosis in viral myocarditis mice and the inhibition is related to regulation of apoptosis-related protein expression.

Objective: To investigate the relationship between serum HGF levels and clinical severity of essential hypertension (EH). Methods: The serum HGF concentrations of 44 patients with EH were measur ed by ELISA. Results: The serum HGF levels in patients with EH w ere higher than that in control. Furthermore, the serum HGF levels of EH patient s with coronary atherosclerosis (CAS) were significantly higher than those of EH patients without CAS ［(920.8±250.0） pg/ml vs （747.9±132.1） pg/ml, P <0.01］ or control ［（643.8±98.2） pg/ml, P<0.01)］.The changes of HGF l evel were correlated with the clinical courses (r=0.63, P<0.01) and stag es (r=0.69, P<0.01) of hypertension. Conclusion: HGF may be considered as a new index for the severity of hypertension and an useful bio chemical parameter for estimating the development of atherosclerosis.

OBJECTIVETo compare the clinical outcomes between China made sirolimus-eluting stents (SES) and bare metal stents (BMS) implantation in patients with acute myocardial infarction (AMI).

METHODSConsecutive patients with AMI underwent primary percutaneous coronary intervention (PCI) were randomly divided into SES group (n = 87) and BMS group (n = 86). The incidence of major adverse cardiac events (MACE including death, reinfarction, in-stent thrombosis, restenosis rate, target vessel revascularization) up to 6 months post PCI were assessed.

RESULTSPostprocedure vessel patency, enzymatic release, cardiac function, and the incidence of short-term MACE were similar between the two groups (all P > 0.05). Two in-stent thrombosis was diagnosed in the SES group and bare stents group respectively (2.4% vs. 2.3%, P > 0.05). At 6 months, In-stent restenosis rate (4.5% vs. 40.0%, P < 0.01) and the in-segment restenosis rate (6.8% vs. 44.9%, P < 0.01) as well as MACE (8.0% vs. 24.4%, P < 0.01), which is mainly due to a marked reduction in the risk of target vessel revascularization (3.4% vs. 11.6%, P < 0.05) were significantly lower in SES group compared to BMS group.

CONCLUSIONThe China made SES were not associated with an increased risk of in-stent thrombosis but significantly reduced restenosis rate and MACE at 6 months post primary angioplasty in patients with AMI.
