Objective To investigate the effect of comprehensive intervention including education, lifestyle intervention and drug intervention for patients with hypertension in Kailuan community. Methods Employees who took part in the health checkup of Kailuan Group, Ltd. from June 2008 to June 2009 were enrolled in this study. The changes of hypertension awareness, treatment and control rates and cardiovascular health behaviors and factors have been observed in the follow-up. Results A total of 5 361 patients with hypertension were enrolled. After a period of 2 years of follow-up, the treatment rate and up to standard rate hypertension were significantly increased compared to pre-intervention (11.90%vs. 100.00%;0.82% vs. 36.93%. P<0.01). After comprehensive intervention, the average score of ideal cardiovascular health behaviors and factors increased from (6.85 ± 1.90) to (7.52 ± 1.92) (P<0.01). Conclusion Comprehensive intervention is an effective means for the prevention and control of hypertension in the community.

Objective To explore the significance of activated protein C resistance (APCR) and antiphospholipid antibody(APA) in patients with neuropsychiatric lupus erythematosus(NPLE). Methods APCR, anticardiolipid antibody (ACA)(IgG, M, A), lupus anticoagulant (LA) were measured with APTT? APC, ELISA, PTT－ LA methods, respectively, in 21 NPLE patients and 88 SLE patients without NPLE(NNPLE). Results The positive rates of APCR and ACA(IgG) in NPLE group were 78.9％ (15/19) and 52.4％ (11/21), respectively, which were significantly higher than those in NNPLE group: 44.3％ (39/88) and 22.7％ (20/88), respectively (P

Objective To explore the effect of tiotropium bromide combined with ambroxol hydrochloride oral liquid on chronic obstructive pulmonary disease (COPD) at remission.Methods According to the digital table, 38 patients with COPD at remission were randomly divided into treatment group and control group .The control group was given with conventional treatment ,and anti-infection and symptomatic treatment when acute attacking ,while the treatment group was treated with inhaled tiotropium bromide and ambroxol Hydrochloride oral liquid base on the con -trol group.Both groups were treated and observed for 6 months.Times of expectoration and acute attack of COPD were observed,and scores of COPD Assessment Test ( CAT) were noted everyday during therapy .Results Compared with the control group ,the total times and means of expectoration in treatment group were much less ,with very significant statistical difference(t=5.19,P<0.05);the cases,times and means of acute attack of COPD were obviously less than those in control group,with very significant statistical difference (t=2.92,P<0.05);the total scores and means of CAT in treatment group were much lower,with significant statistical difference(t=2.65,P<0.05).Conclusion With long-term treatment ,inhaled tiotropium bromide combined with ambroxol hydrochloride oral liquid can effectively decrease the times of expectoration and acute attack in patients with COPD at remission,and improve their qualities of life.

Purpose　The aim is to obtain the cDNA sequence of encoding extramembrane human FL gene with high level expression in E.coli. Methods　The primers were designed based on the known FL cDNA sequence. The total RNA was isolated from fetal liver cells , and then RT-PCR was performed. The fragment was cloned into pUC-18T vector, and further sequenced by automatic sequence analyzer. The gene was inserted into GST fusion expression vector between BamH Ⅰ and EcoR Ⅰ sites. The recombinant plasmid was transformed into E.coli strain DH5 α and induced with 1mmol/L IPTG.Results　The 546bp DNA fragment was amplified by RT-PCR method from fetal liver cells and its sequence was identical to the published sequence encoding human FL. The expressed fusion protein, with molecular weight of about 22kD, was about 10% of the total bacteria protein by SDS-PAGE and densitometry analysis.Conclusion　cDNA was cloned successfully. This study provided a basis for the further fundamental research and clinical application of FL.

The wild type cells of human stomach glandular carcinoma, cell line BGC 823, were treated firstly by a chemical carcinogen (MNNG) for the induction of mutagenesis, then the cells were selected in medium with gradually increasing amount of 8-AG (8-azaguanine) from 1-20?g/ml. It was found that the mutant cells could grow vigorously in the medium containing 20?g/ml of 8-AG but not in HAT medium. The HGPRT assay showed an obvious quantitative difference between the wild type and HGPRT mutant cells of BGC 823.

Objective To investigate the relationship between the anti-phospholipid antibodies (APLs)and activated protein C resistance (APCR). Methods The response to activated protein C (APC) was studied by an APTT-based (clotting) assay with a Stago autoanalyzer and expressed as the ratio between the APTT obtained in the presence and absence of exogenous APC. APC sensitive ratio higher than 2 was regarded as APCR. Anti-?2-glycoprotein Ⅰ (?2GP-Ⅰ) antibody and anti-cardiolipin antibodies (ACL) were measured by an enzyme-linked immunosorbent assay (ELISA). Lupus anticoagulant (LA) was tested by activated partial thromboplastin time (APTT). Results The existence of LA and acquired APCR showed significant correlation (?2=16.332, P=0.008). Acquired APCR was significantly associated with the presence of anti-?2GP-Ⅰ antibody (?2=6.179, P=0.012), but not ACL. The presence of APCR was associated with an increased frequency of history of thromboembolic events and/or recurrent abortions (?2=7.347, P=0.01). Conclusion This study suggests that APCR is linked to the presence of LA and anti-?2GP-Ⅰ antibody. APLs may interfere with the activation of protein C. APCR phenotype may be a major risk factor for thrombophilia in patients with APLs. Combined detection of APLs has the potential value for predicting thrombosis.

Objective To analyze the clinical and biological features of mixed acute leukemia(MAL).Methods Bone marrow specimens of 38 MAL patients were evaluated to prove the diagnosis and the classification by morphoiogic,immunologic examinations.These patients were treated with protocols suitable for both acute myeloid leukemia(AML)and acute lymphoblastic leukemia(ALL).Results All MAL patients had a leukemia syndrome.Morphologically,the subtypes of M1,M2 and M5 were predominant in AML,as L2 Was in ALL.Immunologically,coexpression of myeloid and B lineage associated antigens was predominant,about 68.4%;cytogenetically,Ph chromosome was observed in 33.3%(5/15)of MAL patients,and immunophenotype was B-M;1 Ph chromosome(+)MAL patient,fusion gene bcr-abl 190(+)and immunophenotype was B-M.In 38 cases,32 patients received chemotherapy.The complete remission rate was 28.1%(9/32).CR of.normal karyotype was significantly higher than that of abnormal ones.Conclusion Patients with MAL have unique biological features and the complete remission rate was low and the prognosis was poor.

Objective To analyze the treatment efficacy and safety of a modified GMALL protocol for adult acute lymphoblastic leukemia (ALL). Methods Data of 37 patients with newly diagnosed adult ALL treated with a modified GMALL protocol from January 2005 to December 2009 were retrospectively analyzed,and compared with that of 44 patients treated with an in-house conventional protocol at the same period.Results The complete remission (CR) rate was 89.2 %(33/37) treated with modified GMALL protocol. The cumulative overall survival (OS) rates at 1 year, 2 years, 3 years and 4 years were 77.5 %, 48.0 %, 40.0 %and 40.0 %, respectively. The main adverse events were grade 3 or grade 4 hematological toxicities and infections which were easily managed, and the treatment-related mortality rate was low. The OS of modified GMALL protocol was superior to that of the conventional protocol. Conclusion The modified GMALL protocol has a satisfying effect and the adverse events can be tolerated for adult ALL, so its clinical application can be encouraged.
