Objective To investigate the effect of chain management on education among hypertensive patients of the community. Methods A total of 144 cases of hypertension patients in community were selected as the research objects, they were divided into the control group(72 cases, from February to July 2015) and the countryside group (72 cases, from September 2015 to February 2016).The control group was given routine education, and the countryside group received education with chain management. The treatment compliance and blood pressure values were compared between the two groups before and after intervention. Results The score of patients behavior of drug compliance, adverse drug, self life management and cigarettes-alcohol addiction management after intervention in the countryside group were (20.32±4.41), (34.62±5.08), (41.27±3.54), (10.02±1.79) points, while they were (13.41±3.07), (26.23 ± 5.12), (39.78 ± 2.47), (7.94 ± 1.83) points in the control group. And the scores of the countryside group were significantly higher than those of the control group (t=2.930-9.864, P<0.05). There were no significant differences in the systolic blood pressure, diastolic blood pressure and mean arterial pressure before the intervention between the two groups (P > 0.05). The systolic blood pressure, diastolic blood pressure and mean arterial pressure after intervention in the countryside group were (129.63 ± 8.07), (80.12 ± 7.62), (87.43 ± 9.35) mmHg(1 mmHg=0.133 kPa), while they were (135.42 ± 8.13), (87.56 ± 7.79), (99.31 ± 8.72) mmHg in the control group, and there were significant differences(t=4.295, 3.800, 9.201, P<0.01). Conclusions The chain management mode of community hypertension patients with education, can effectively improve the control of blood pressure in patients, improve the treatment compliance of patients.

The feasibility of frontal chromatography for determining the complexation stability constant KML and total mole of binding site Λo was demonstrated by the accuracy and precision binding experiments between metal ions (Cu2+, Ni2+ and Co2+) and chelating ligand (IDA), in which R2>0.98 and RSD <5%.To further prove the universality of the frontal chromatography, the changing rules of KML values between Cu2+, Ni2+, Co2+ and IDA, Asp, L-Glu were examined under NaAc-HAc, Na-PB and Tris-HCl buffer systems.The results showed that the binding strength of chelating ligands for metal ions followed IDA>Asp>Glu;binding strength of metal ions for chelate ligands followed Cu2+>Ni2+>Co2+;and the binding effect with NaAc-HAc buffer was the best.In aqueous solution, quantum computing of binding energy (ΔE) and gibbs free energy (ΔG) between chelating ligand and metal ion was performed at the M06/6-311++G (d, p) level.According to ΔE and ΔG, the binding rules between chelating ligand and metal ion were predicted theoretically.These rules were basically in agreement with above experimental results.The present work provided effective method for studying on binding characteristics of metal ions for aminocarboxyl chelating ligands, thus exhibited a good foundation for improving the stability of immobilized metal affinity chromatographic column and solving the leakage of metal ions from the column in the process of competitive elution.

Objective:To investigate the effect of acute myocardial infarction (AMI)-activated inflammation on adipokine imbalance and the therapeutic effects of statin.Methods:A total of 32 C57BL/6 mice were divided into 4 groups:a sham group,an AMI group,a low-dose atorvastatin [2 mg/(kg.d)] group and a high-dose atorvastatin [20 mg/(kg.d)] group.AMI models were established by surgical coronary artery ligation.Plasma levels of high sensitive C reaction protein (hs-CRP),adiponectin and resistin were measured.Adiponectin and resistin expressions were determined.In addition,mouse 3T3-L1 preadipocytes in vitro were differentiated and they were stimulated by oxidized low density lipoprotein (ox-LDL).The protein expressions of adiponectin and resistin in adipocytes were detected.The effects of atorvastatin on ox-LDL-induced adipokine imbalance in adipocytes were identified.Results:The plasma levels of hs-CRP and resistin in AMI mice were significantly increased,whereas the plasma levels of adiponectin were remarkably decreased.However,atorvastatin treatment blocked the changes in the plasma levels of hs-CRP,resistin and adiponectin in AMI mice in a dose-dependent manner.Consistent findings regarding the adipose expressions of the two adipokines were obtained.The plasma levels of hs-CRP were positively correlated with resistin but negatively with adiponectin.In vitro study,ox-LDL increased resistin protein and adiponectin expressions in adipocytes,which were dose-dependently reversed by atorvastatin.Conclusion:Inflammation activation in AMI mice leads to adipokine imbalance.Atorvastatin ameliorates the AMI-induced adipokine imbalance via anti-inflammation.
