Aim: To investigate the effect of endogenous nociceptin/orphanin FQ(N/OFQ) on arrhythmias induced by myocardial ischemia/reperfusion (I/R) in rats and the role of microRNA-1 (miR-1) in it. Methods: Twenty-four Sprague-Dawley rats were randomly divided into sham-operation group (Sham group), ischemia/reperfusion group (I/R group) and the pretreatment of N/OFQ receptor antagonist (UFP-101) group(U + I/R group). The model of myocardial ischemia/reperfusion was prepared by ligating the left anterior descending branch of the coronary artery of rats. The incidence and arrhythmogenic scores during reperfusion in rats were recorded and analysed. The myocardium at the risk of ischemia was collected at 120 min after reperfusion. MiR-1, GJA1 and KCNJ2 levels were detected by qRT-PCR and Cx43 and kir2. 1 protein levels were detected by Western blot. Results: Antagonism of endogenous N/OFQ could significantly reduce reperfusion arrhythmias and arrhythmogenic scores, compared with I/R group (P < 0. 01). The qRT-PCR and Western blot results suggested that compared with sham group, miR-1 expression significantly increased in I/R group(P < 0. 01), while the expression of Cx43, Cx43 mRNA and kir2. 1 decreased(P< 0. 05); compared with I/R group, pretreatment with UFP-101 led to reduction of miR-1 (P<0. 05) and rise of Cx43 and kir2. 1 (P < 0. 05). Conclusions: Endogenous N/OFQ up-regulates miR-1 and inhibits the expression of Cx43 and kir2. 1 proteins, leading to reperfusion arrhythmias in rats.

Objective To observe the clinical efficacy of bloodletting and cupping at Fengchi (GB 20) plus acupuncture in treating peripheral facial paralysis in acute stage.Method Sixty patients with peripheral facial paralysis in acute stage (disease duration ≤7 d) were randomized into a treatment group and a control group, 30 cases in each group.

Objective To study the efficacy of trimctazidine combined with atorvastatin for primary hypertension with paroxysmal auricular fibrillation,and its effects on LAD and CRP. Methods 160 patients of pri-mary hypertension with paroxysmal auricular fibrillation were randomly divided into 4 groups. Forty patients were treated with amiodarone (control group),600 mg/d for the first week,400 mg/d for the second week and 200 mg/d later;40 patients were treated with atorvastatin (20 mg/d,3 times per day) in addition to amiodarone (the atorvasat-in group);40 patients were treated with trimetazidine (20 mg/d,3 times per day) in addition to armiodarone (the trimetazidine group);40 patients were treated with combination of trimetazidine and atorvastatin in addition to amiod-atone (the combination group),and the dose was the same as the above groups. The treatment was started within 24 hours of recovering from paroxysmal auricular fibrillation and lasted for 1 year. Results After 1 year there was 1 pa-the control group,and 62.5% (25/40) for the atorvasatin group,64.1% (25/39) for the trimetazidine group,and 84.6% (33/39) for the combination group. Compared to the control group,the effective rate of the 3 treatment groups were all significantly higher (X2=4.56、5.13、17.55,P<0.05). The effective rate of the combination group was significantly higher than that of the atorvasatin group and the trimetazidine group (X2=4.95、4.30,P<0.05),and there was no significant difference of effective rate between the atorvasatin group and the trimetazidine group(X2= >0.05). After treatment LAD was (40.96+1.81) mm in the control group,(38.65±1.90) mm in the atorvasatin group,(39.15±1.85)mm in the trimetazidine group,and (37.22±1.74) mm in the combination group. LAD of the 3 treatment groups were all significantly different from the control group(F=3.42,P<0.05). LAD of the combina-tion group was significantly smaller than that of the atorvasatin group and the trimetazidine group (P<0.05),and there was no significant difference of the LAD between the atorvasatin group and the trimetazidine group(P>0.05). There was no significant difference between the 4 groups on CRP before treatment (F=0.96,P>0.05). After treat-ment CRP was (8.85±1.45) mg/L in the control group,(5.96±1.26) mg/L in the atorvasatin group,(6.81± 1.37) mg/L in the trimetazidine group,and (3.75±1.15) mg/L in the combination group. CRP of the 3 treatment groups were all significantly different from the control group (F=3.63,P<0.05). CRP of the combination group was significantly lower than that of the atorvasatin group and the trimetazidine group (P<0.05),and there was no signif-icant difference of CRP between the atorvasatin group and the trimetazidine group (P>0.05). Conclusion The treatment with trmetazidine combined with atorvastatin could prevent recurrence of paroxysmal auricular fibrillation though anti-inflammatory and inhibiting the remodeling of left atrial.

Objective By in vitro culture of mouse macrophage cell line RAW264. 7 and primary mouse bone marrow macrophages, the expression of Siglec-1 when stimulated by ox-LDL was observed. Meanwhile, Siglec-1 was up-regulated by M-CSF and down-regulated by small interference RNA targeting Siglec-1 ( si-RNA-Siglec-1) , and the expression of chemokines and lipid uptake ability by macrophages were observed, to explore the role of Siglec-1 on macrophages in atherosclerosis. Methods LDL was oxidized by copper. According to preliminary experiment results, ox-LDL 100 μg/ml was selected as a stimulus. There were 6 experimental groups:normal control group,ox-LDL 100 μg/ml group, ox-LDL 100 μg/ml + si-RNA 2509 2 ng/ml group,ox-LDL 100 μg/ml + si-RNA 3618 2 ng/ml group,ox-LDL 100 μg/ml + M-CSF 5 ng/ml group and ox-LDL 100 μg/ml + M-CSF 10 ng/ml group. si-RNA-Siglec-1 was transfected into macrophage to inhibit the expression of Siglec-1, whereas M-CSF 10 ng/ml or 5 ng/ml were added into the culture medium to enhance the expression of Siglec-1. Quantitative real-time polymerase chain reaction ( qRT-PCR) was used to determine the interfere efficiency of si-RNA-Siglec-1 or M-CSF. After stimulation with ox-LDL for 48 h, cell culture supernatants were collected to determine MIP-1 alpha, MCP-1 and IL-8 concentration by ELISA (n =3 for each group) to evaluate the activation of macrophages. Internalization of lipid particles by macrophages was analyzed by oil red 0 staining. Results Observed by fluorescence microscope, si-RNA-Siglec-1 could be effectively transfected into macrophages with a transfection efficiency about 90% ;PCR results showed that si-RNA 2509 and si-RNA 3618 in a concentration of 40 pmol/L had an inhibition rate of 0. 54 ±0. 11 or 0. 52 ±0. 16 vs 1. 00 ±0. 24 (control group) , t =5. 227 and 4. 992, respectively, all P < 0.01, while M-CSF 10 ng/ml could increase Siglec-1 mRNA expression approximately 4-fold (4. 16 ± 1. 25 vs 1.00 ±0. 24, t =7. 448, P<0. 01). The secretion of MCP-1, MIP-1 alpha, and MIP-2 in si-RNA3618-Siglec-1 group [(359. 28±47. 80) pg/ml, (33. 76 ± 14. 28) ng/ml and (7.87±1.55) ng/ml for MCP-1,MIP-1 alpha, and MIP-2, respectively] was significantly reduced in compare with ox-LDL 100 μg/ml group [ (577. 89 ± 35. 95 ) pg/ml, (69. 17 ± 11. 82) ng/ml and (12.28 ± 1.19) ng/ml for MCP-1, MIP-1 alpha, and MIP-2, respectively], with P value of 0.01, 0.05 and 0.01. In contrary, ox-LDL 100 μg/ml plus M-CSF 10 ng/ml group could significantly promote macrophage chemokine secretion [ (672. 89 ± 43.80) pg/ml, (101.31 ±24.17) ng/ml and (14.81 ±0.54) ng/ml for MCP-1, MIP-1 alpha, and MIP-2, respectively], with P < 0.05 compared with ox-LDL 100 μg/ml group. Meanwhile, lipid intemalization and foam cell formation was inhibited in si-RNA3618-Siglec-l group while ox-LDL 100 μg/ml plus M-CSF 10 ng/ml group could enhance the phagocytosis of ox-LDL by macrophage. Conclusions Siglec-1 may served as a potential phagocytic receptor for ox-LDL involving in macrophage uptake of lipid and turn into foam cells. Furthermore, it can active macrophages and enhance the secretion of MIP-1 alpha, MCP-1 and IL-8, attracting more macrophages and lymphocytes to the site of inflammatory plaque. Targeted inhibition of Siglec-1 reduces macrophage uptake of lipid and secretion of chemokines. Siglec-1 may possibly serve as a potential target of treatment or delay the development of atherosclerosis.
