OBJECTIVE:To study related factors of ACEI/ARB drugs in hypertension patients with coronary heart disease. METHODS:Six hundred hypertension patients with coronary heart disease were selected from a hospital during Jan. 2012-Jan. 2015,310 patients receiving ACEI/ARB drugs were included in observation group,and 290 patients not receiving these drugs were included in control group. General information and lab indexes of 2 groups were collected and analyzed. RESULTS:There were sta-tistical significances in ambulatory arterial stiffness indexes [(0.57±0.13),(0.40±0.11)],24 h average systolic blood pressure [ (146.42±11.24)mmHg,(132.31±9.85)mmHg],24 h average diastolic blood pressure [(78.14±9.21)mmHg,(82.79±8.33) mmHg],24 h ambulatory pulse pressure [(64.89±13.57)mmHg,(53.54±9.78)mmHg],drinking rate(58.71%,28.28%),moder-ate intensity rate(31.29%,65.17%),BMI[(33.28±2.07)kg/m2,(23.17±2.86)kg/m2],LVEF [(35.65±11.42)%,(48.01± 12.45)%],dyslipidemia rate(66.77%,30.34%),myocardial infarction rate(68.39%,39.66%),revascularization rate(69.68%, 33.10%)and duration of coronary heart disease between 2 groups(P<0.05). The duration of coronary heart disease,dyslipid-emia,myocardial infarction,revascularization were included in multivariate Logistic regression analysis,with statistical signifi-cance(P<0.05). CONCLUSIONS:The application of ACEI/ARB drugs in hypertension patients complicated with coronary heart disease is influenced by many factors;dyslipidemia,myocardial infarction and revascularization are positive independent influential factors of ACEI/ARB drug use in the treatment,but drug use rate will decline with the duration increase.

Objective To study the effects of discoidin domain receptor 1 (DDR1) mediated phosphorylation of protein Tau on hypoxic-ischemic brain damage (HIBD) in neonatal rats and its possible mechanism.Methods Sixty-four seven-day-old male specific-pathogen-free Wistar rats were randomly divided into four groups with sixteen in each: Sham, HIBD, HIBD with normal saline (HIBD+NS) and HIBD with DDR1 inhibitor (HIBD+DI) groups. A rat model of HIBD was established by subjecting the rats to left common carotid artery ligation, followed by exposing them to hypoxia for two hours. In HIBD+DI group, the inhibitor of DDR1 was immediately injected into lateral cerebroventricles of the rats following modeling. Forty-eight hours after injection, tissues of left cerebral cortex were collected from each rat to evaluate histopathological changes with HE staining. Western-blotting was used to assess the phosphorylation levels of DDR1 and protein Tau. Enzyme-linked immunosorbent assay was performed to detect the concentrations of acetylcholine. Analysis of variance ort test were used for statistical analysis.Results (1) Damages in cerebral cortex: Percentages of abnormal neurons in the rats of HIBD group were higher than those in Sham group [(80.28±4.51)% vs (10.40±2.17)%,t=39.491,P<0.01]. Pyknotic or necrotic neurons in the rats of HIBD+DI group were less than those in HIBD+NS group [(31.91±3.05)% vs (82.01±7.20)%,t=18.123,P<0.01]. (2) Phosphorylation of DDR1 and protein Tau: Levels of phosphorylated DDR1 in the cerebral cortexes of rats in HIBD group were higher than those in Sham group (0.922±0.199 vs 0.095±0.023,t=10.379,P<0.01), and those levels in HIBD+NS group were higher than those in HIBD+DI group (1.200±0.171 vs 0.255±0.111,t=11.901, P<0.01). The phosphorylation of protein Tau was similar to that of DDR1 (0.919±0.228 vs 0.194±0.224 in HIBD and Sham groups,t=7.347; 1.100±0.167 vs 0.291±0.210 in HIBD+NS and HIBD+DI groups,t=9.447;bothP<0.01). (3) Levels of acetylcholine: Levels of acetylcholine in cerebral cortexes of rats in HIBD group were lower than those in Sham group [(3.685±0.472) vs (7.429±0.861) ng/g protein,t=10.781,P<0.01], and that levels in HIBD+DI group were higher than those in HIBD+NS group [(7.058±0.915) vs (2.521±0.723) ng/g protein,t=10.989,P<0.01].Conclusions Activation of DDR1 plays a key role in enhancing the phosphorylation of protein Tau and in reducing the secretion of acetylcholine in cerebral cortexes of rats with HIBD. Inhibitor of DDR1 could protect neonatal rats from HIBD through the decreasing of protein Tau phosphorylation and increasing of acetylcholine release by inhibiting the activation of DDR1.

Objective To study the effect of high-glucose-high-fat diet on expression and methylation of insulin receptor ( INSR) gene in F1 offspring. Methods Sixty 5-week-old male SD rats were randomly divided into two groups:normal diet group and high-glucose-high-fat diet group. After rats were fed for three months, all male rats were performed to copulate with normal female rats. The body weight, blood glucose, and blood insulin of neonatal rats of F1 offspring were measured. The genome DNA, total RNA, and total protein were extracted from livers, brains, and muscles of neonatal rats. Relative expression of INSR in both mRNA level and protein level were detected using a realtime PCR test and a Western blot test respectively. Methylation of INSR promoter was analyzed by a methylation specific PCR ( MSP ) . Results Both body weight and fasting glucose were without significant difference in two groups. In high-glucose-high-fat diet group, both the glucose tolerance and insulin tolerance of neonatal rats in F1 offspring were significantly decreased. Except that in brains, the expressions of INSR gene in livers and in muscles of neonatal rats in high-glucose-high-fat diet group were down-regulated in mRNA ( realtime PCR ) and protein levels ( Western blot) compared to the normal diet group. Meanwhile, the methylation of INSR gene in livers and muscles were strengthened in high-glucose-high-fat diet group. Conclusion A high-glucose-high-fat diet fed to male SD rats leads to the decrease in glucose tolerance, insulin tolerance, and the inhibition of expression of hepatic and muscle INSR gene in neonatal offspring. The methylation of INSR gene could be involved in this phenomenon.

ObjectiveTo study the sirolimus (SRL)-associated interstitial pneumonitis,which is a severe side effect of sirolimus therapy. Methods In 7 renal grafts treated with SRL, interstitial pneumonitis (8 times) was diagnosed. One patient suffered a relapse after sirolimus treatment was given again. Two patients received de novo sirolimus treatment, and rest 5 patients were switched from a calcineurin inhibitor-containing regimen to a SRL-based protocol for various indications: chronic allograft nephropathy (n = 4) and cancer (n = 1 ). The patients presented with fever, dyspnea on exertion and the chest X-ray or computed topographic (CT) scan on admission showed bilateral mostly peripheral interstitial infiltrates. ResultsSRL was discontinued in 4 patients and the dose was reduced in the remaining 3 patients. Symptoms were improved within 3-14 days in all patients, the radiographic findings improved within 2-4 weeks, and the lesions were absorbed completely in 2-6 months.ConclusionThe frequency of interstitial pneumonitis appears to be increased in renal transplant patients receiving SRL. Discontinuation or reduced dose of SRL appears to be the safest treatment option for the patients with interstitial pneumonitis.

Objective To observe the clinical efficacy of staphylococcal protein A immunoadsorption plus nonmyeloablative chemotherapy with CD34+ autologous peripheral blood stem cell transplantation in the treatment of refractory systemic lupus erythematosus (SLE). Methods Three patients with active SLE were enrolled into this study. All patients were diagnosed with lupus nephritis by renal biopsy and poorly responded to routine therapy. Before transplantation, patients were given 6 sessions of immunoadsorption apheresis using columns of staphylococcal protein A-silica with an interval of 3 days; each session processed 3 L plasma and a total of 18 L plasma was processed over the 6 treatments. Three days following the immunoadsorption apheresis, the mobilization of stem cells was realized by intravenous cyclophosphamide at a dose of 2 g per square meter of body surface area and subcutaneous recombinant human granulocyte colony-stimulating factor (G-CSF) at a dose of 5 g per kilogram of body weight per day for 5 days. Then, peripheral blood raonoclonal cells were obtained by CS-3000 Cell Separator, and passed through the Clini Macs CD34+ cell selection device, with the final concentration of CD34+ cells being 2.6×106, 2.1×106 and 2.4×106 per kilogram of body weight respectively, and that of CD3+ cells being 3×105, 2.1×105, and 2.0×105 per kilogram of body weight, respectively, in these three patients. The conditioning regimen consisted of oral fludarabine of 50 mg/d for 5 days plus intravenous pig anti-human thymocyte immunoglobulin (ATG) at a daily dose of 90 mg/kg for 5 days. After 72-hour treatment with ATG, the frozen stem cells were infused back to the patients. Clinical manifestations and lupus-correlated immune parameters were compared in patients at baseline and after transplantation. Results Following immunoadsorption apheresis, an obvious decrease was observed in the level of serum anti-dsDNA, antinuclear antibody and IgG antibodies, while an increase in the level of serum complement 3. All patients achieved the reconstruction of hemopoiesis 2-3 days after the transplantation. Also, an apparent clinical remission was achieved with the SLEDAI score being less than 3. Six months after the transplantation, serum anti-dsDNA and antinuclear antibodies as well as urine protein were undetectable, the level of complement 3 reached the normal range, and renal function was restored. Conclusions Staphylococcal protein A immunoadsorption plus nonmyeloablative CD34+ autologous peripheral blood stem cell transplantation are effective and safe for refractory SLE, but the long-term effect remains to be connfirmed by further studies.

Objective To study the right ventricular function of patients with pulmonary thromboembolism by using color Doppler ultrasound.Methods 31 patients with acute pulmonary thromboembolism,compared with 31 vohnteers,were enrolled in this study.The right ventricular anterior wall movement,right ventricular end diastolic volume,right ventricular ejection fraction,and myocardial performance index were observed by echocardiography.Resuits The right atrium diameter,right ventricles diameter,right ventrieular end diastolic volume and pulmonary artery inner diameter in study group were much larger than that in control group (P<0.01),and the right ventricular anterior wall movement and right ventrieular ejection fraction decreased in study group (P<0.01).Tricuspidal annular E peak velocity tended to be decreased,isovolumie relaxation time and isovolumic contraction time were prolonged and myocardial performance index was increased (P<0.01).Right ventricular myocardial performance index showed significant correlation with right ventrieular ejection fraction (r=0.78,P<0.01),isovolumic relaxation time and isovolumic contraction time(rl=0.88,r2=0.57,P<0.01).Conclusion The right ventricular function in patients with pulmonary thromboembelism is decreased and myocardial performance index is a sensitive index which can be used to reflect right ventricular function in pulmonary thromboembolism.

Objective To observe the effect of scalp acupuncture and rehabilitation training on the regulation of neuro-plasticity-associated protein MAP-2 in gerbils modelling cerebral ischemia and reperfusion.Methods Cerebral ischemia and reperfusion were modelled into thirty-six male gerbils.They were then randomly divided into a model group (A),a scalp acupuncture and rehabilitation training group (B) and a rehabilitation training group (C),each of 12 cases.The scalp acupuncture and rehabilitation training were administered daily to the gerbils in group B beginning 24 h after modeling,for 14 d.Any changes in Bederson scores were observed after one,7 and 14 days.On the 14th day the expression of MAP-2 around the infarct focus was detected using western blotting in all 3 groups.Results On the 7th day the average Bederson score in group B (1.81 ± 0.52) was not significantly different from that in group A (2.13 ± 0.49) or group C (2.00 ± 0.31) (P ＞ 0.05).At the end of the treatment,however,there were significant differences between the groups,with group B (0.47 ± 0.31) scoring significantly better than groups C (1.04 ± 0.63) and A (1.46 ± 0.72) (P ＜ 0.05).Group C was also significantly better than group A (P ＜0.05).The expression of MAP-2 as measured as integrated optical intensity (IOD) in group B (0.91 ±0.18) was significantly higher than that in group A (0.43 ± 0.21) and group C (0.67 ± 0.24) (P ＜ 0.05) ; so was group C compared to group A (P ＜0.05).Conclusion The scalp acupuncture combined with rehabilitation training can improve the recovery of motor function and enhance the expression of neuro-plasticity-associated protein MAP-2 in gerbils with after cerebral ischemia and reperfusion.

Objective To observe the effect of transcutaneous electrical acupoint stimulation (TEAS) on the recovery of gastrointestinal function after laparoscopic intestinal operation.Methods Sixty patients of the selective laparoscopic intestinal resection, 28 males and 32 females, aged 18-65 years, ASA physical status Ⅰ or Ⅱ, were enrolled and randomly allocated into two groups: TEAS group and control group, 30 in each group.Patients in TEAS group accepted transcutaneous electrical acupoint stimulation treatment at Neiguan, Hegu, Zusanli points from the time before induction of anesthesia to 3 days after surgery, and patients in the control group were treated with transcutaneous electrical acupoint stimulation, but the electrode pads were just attached on the related points with no electric stimulation.Plasma motilin concentrations preoperatively, postoperatively 12, 24, 48 and 72 h were measured in the two groups.The recovery time of intestinal peristalsis, anal flatus time, in-hospital time and the incidence of nausea and vomiting within 3 days after operation were observed.Results Compared with the control group, serum motilin concentration postoperative 24 h increased significantly [(218.5±52.3) pg/ml vs (141.8±45.8) pg/ml, P<0.05], the time of intestinal peristalsis recovery [(19.4±3.2) h vs (29.6±7.8) h, P<0.05] and flatus [(23.2±4.7) h vs (36.5±8.9) h, P<0.05] were shorter, the incidence of postoperative nausea and vomiting within 3 days after operation decreased significantly in TEAS group (16.7% vs 36.7%, P<0.05).There was no statistically significant difference of the in-hospital time between the two groups.Conclusion TEAS can promote the recovery of gastrointestinal function in patients undergoing laparoscopic intestinal surgery.

Objective To explore the peripheral blood circulating microRNA expression profile of ischemic and hemorrhagic stroke patients by using microRNA array. Methods The whole blood of 3 patients with acute ischemic stroke, 3 patients with cerebral hemorrhage and 3 healthy volunteers were collected for whole blood RNA through Norgen exosome isolation kit, and then underwent quality and density measurement through PCR. The miRNAs expression profile was studied through μParaflorTM microRNA. All the data were analyzed by associated software and statistics methods. Results 8 miRNAs associated with cerebral stroke in ischemia stroke patients and cerebral hemorrhage patients were discovered, and showed significant difference (P<0.05). 11 differential expression miRNAs were found between ischemia stroke patients and control group, and 24 were found between hemorrhage patients and control group. However, after up-regulation, no significant difference was found (P > 0.05). Conclusions Different expression profiles of miRNA between ischemic stroke patients and hemorrhagic stroke patients may provide insights into their roles in the pathogenesis and progression of stroke. The study of miRNA can contributes to elucidate the epigenetics molecular mechanism of acute stroke.
