OBJECTIVETo explore the therapeutic effect of diagnosis and treatment program of integrative medicine (IM) on level 2 hypertension in the young and middle-aged patients and their ambulatory blood pressure.

METHODSA randomized, placebo parallel and controlled, multi-center clinical trial was performed. Totally 199 young and middle-aged level 2 hypertension patients were randomly assigned to the treatment group (99 cases) and the control group (100 cases). All received combined hypotensive treatment program by taking Nifedipine Sustained Release Tablet and Hydrochlorothiazide as basic drugs. Patients in the treatment group additionally took Western medicine (WM) combined Jiangyabao serial drugs (0.31 g per tablet, 2 tablets each time, twice daily), while those in the control group additionally took WM combined simulative agents of Jiangyabao serial drugs (0.31 g per tablet, 2 tablets each time, twice daily). The treatment course was 8 weeks for all, and 24-week follow-ups performed. 24 h ambulatory blood pressure and casual blood pressure, and their efficacies were compared between the two groups, and safety assessed as well.

RESULTSCompared with before treatment in the same group, daytime and night casual blood pressure, as well as 24 h ambulatory blood pressure were all obviously improved in the two groups (P < 0.01). Average diastolic and systolic blood pressures at night decreased more in the treatment group than in the control group with statistical difference (P < 0.05). There was no statistical difference in total efficacies of daytime casual blood pressure or ambulatory blood pressure (P > 0.05).

CONCLUSIONJiangyabao serial drugs combined WM in treating young and middle-aged level 2 hypertension patients showed obvious effect in improving night blood pressure, especially for night diastolic blood pressure.

Objective To study the expression of signal transducers and activators of transcription 3(STAT3) in airway epithelial cells of asthmatic mouse model and its association with airway remodeling,explore the role of signal-transduction pathway in airway remodeling.Methods Thirty Balb/c mice were randomly divided into normal control group(n=10),asthma without intervention group(n=10) and AG490 intervention group(n=10).The mice were sensitized with ovalbumin to establish the asthmatic model.The histological changes were evaluated by HE staining,total brochial wall thickness(Wat)and smooth muscle thickness(Wam) were measured by image analysis system,the percentages of collagen deposition were detected by Masson′s trichrome staining,the expression of STAT3 in airway were detected by immunohistochemistry technique;lung tissue extracts were analyzed for phosphorylation of STAT3(p-STAT3)by Western blot.SPSS 13.0 software was used to analyze the data.Results 1.The histological changes including airway thickness,airway smooth cell proliferation and excessive collagen deposition in subepithelial aera were found under light microscope in asthmatic mice.2.The level of STAT3 and p-STAT3 in asthma without intervention group were significantly higher than those in normal control group(Pa

Objective To observe the effects of inhaled budesonide (BUD) in early phase on the airway inflammation in asthmatic mouse,and its effects on the IL-6/signal transducers and activators of transcription 3(IL-6/STAT3 )signaling pathway in airway,explore the therapeutic target of BUD.Methods Forty Balb/c mice were randomly divided into control group(n=10),asthma group(n=10),BUD group(n=10) and AG490 group(n=10).The mice were sensitized with ovalbumin to establish the asthmatic model.The histological changes were evaluated by HE staining.The levels of IL-4,IL-5 and IL-6 in bronchoalveolar lavage fluid (BALF) were measured by enzyme-linked immunosorbent assay.Lung tissue extracts were analyzed for total STAT3 and phospho-STAT3(p-STAT3) by Western blot.Results 1.The levels of inflammatory cells,EOS%, IL-4,IL-5 and IL-6 levels in the BALF in BUD group were significantly lower than those in asthma group (Pa0.05).Conclusions Inhaled corticosteroid can apparently ameliorate airway inflammation in early phase in asthmatic mouse model,and it can downregulate the expressions of IL-6 and STAT3,inhibit the signal-transduction pathway of STAT3.The IL-6 /STAT3 signaling pathway of airway may be one of the potential therapeutic targets of inhaled corticosteroid.

Objective To systematically review the efficacy and tolerance of levofloxacin-based rescue regimens for H.pylori eradication failures.Methods A search of Medline,Embase,Cinahl, CBM-disc was performed.Randomized controlled trials comparing levofloxacin-based triple therapy with bismuth-based quadruple therapy were selected for meta-analysis.Assessment of study quality and ex- tracting data to calculate eradication rate and side effect rate.Results Seven randomized controlled stud- ies met the inclusion and exclusion criteria were recruited.Ten-day levofloxacin-based triple therapy was more effective(86.9% vs 61.8% P

OBJECTIVETo investigate the potential of Gomphidius viscidus, a kind of ectomycorrhizal fungi, for phytoremediation of anthracene in soil.

METHODSAbsorptioe changes of micro-habitat were studied in detail.

CONCLUSIONEctomycorrhizal plants have a strong potential for remediation of polycyclic aromatic hydrocarn characteristics of both active and inactivated mycelia.

RESULTSA high calculated adsorption capacity of 1,886.79 mg/g and 1,515.15 mg/g at 25 °C, pH 6.0 for active and inactivated mycelia respectively, was obtained based on Langmuir model. The ANT biosorption was more ideally characterized by the Langmuir model than by the Freundlich model. The biosorption of anthracene to biomass was extremely fast and could be modeled with pseudo-second order adsorption kinetics. Moreover, ectomycorrhizal mycelia demonstrated a strong ability to adjust the physiological process to get adapted to the change of micro-habitat.

Fifty-six patients with Graves' ophthalmopathy(GO)were treated with antithyroid drug and oral prednisone for three months,TSH receptor antibody(TRAb)level was reduced,GO activity and severity of some patients were ameliorated but still positively associated with TRAb.It suggests that TRAb not only triggers off GO but also plays a possible role in the maintenance of the autoimmune process in GO.

Objective To compare the diagnostic value of myocardial perfusion imaging (MPI) and 64 multi-slice spiral CT (64-MSCT) for coronary artery disease (CAD). Methods Fifty-two patients with suspected or known CAD were included in the study. Each patient underwent both stress and rest MPI,MSCT as well as conventional coronary angiography (CAG) within 1 month. The stress and rest MPI were scored by a 5-grade criteria (0 ～ 4) based on 17 coronary artery segments. The difference between summed stress and rest scores ＞ 1 was defined as myocardial ischemia. Stenosis in one main vessel or one main branch of the main vessel ≥50% was defined as myocardial ischemia by MSCT. CAG was used as the reference for comparison. Statistical analysis was performed using SPSS 13. 0 software. Kappa value was used to test the accordance of MPI and MSCT results. X2 test was used to evaluate the difference between MPI and MSCT results. Results The patient-based sensitivity, specificity, positive and negative predictive values and accuracy of MPI and MSCT for the diagnosis of CAD were 86.7% (26/30), 77.3% ( 17/22),83.9% (26/31), 81.0% ( 17/21), 82.7% (43/52) and 83.3% ( 25/30), 86.4% ( 19/22), 89.3%( 25/28), 79.2% ( 19/24), 84.6% (44/52), respectively. The vessel-based sensitivity, specificity, positive and negative predictive values and accuracy of MPI and MSCT were 74.5% (38/51), 81.0% (85/105 ), 65.5% (38/58), 86.7% ( 85/98), 78.8% ( 123/156 ) and 90.2% (46/51 ), 88.6% ( 93/105 ),79.3 % (46/58), 94.9% (93/98), 89.1% ( 139/156), respectively. There was no statistically significant difference between MPI and MSCT for either patient or lesion-based diagnosis (X2 =0.44, 0.21, both P ＞0.05 ). 96.0% (24/25) patients with both abnormal MPI and MSCT positive were valified by CAG while 83.3% (15/18) patients with both MPI and MSCT negative were excluded by CAG. Conclusions Both MPI and MSCT are reliable diagnostic modalities for CAD. They also provide complementary diagnostic value to each other.
