Chinese Journal of Primary Medicine and Pharmacy 2012;19(7):989-990
ObjectiveTo investigate the expression and clinical significance of myeloperoxidase (MPO) in patients with chronic ischemic cerebrovascular disease.Methods70 carotid atherosclerotic plaques patients with plasma MPO level in our hospital were measured and taken ultrasound examination at the same time.ResultsThere was no significant difference for those with contrast-enhanced imaging and without increase in the general information (P >0.05).The enhanced infarct rate was 80.5% (33/41).The non-enhanced infarct was 44.8% (13/29).The carotid plaque ultrasound contrast enhancement in patients with cerebral infarction group was significantly higher than non-enhanced group(P < 0.01 ).In the plasma levels of MPO detection,contrast-enhanced carotid ultrasound group was significantly higher than non-enhanced group( P < 0.01 ).The cerebral infarction patients was significantly higher than non-cerebral infarction group (P < 0.01 ).ConclusionThe atherosclerotic plaque instability in patients with high expression level of MPO was significantly higher,which indicated high level expression of MPO in the diagnosis of chronic cerebrovascular disease had a very important role.Supplemented by the results of ultrasound imaging may had a clear diagnosis.

Chinese Journal of Primary Medicine and Pharmacy 2015;(22):3407-3409
Objective To observe the protective effects with vascular endothelium of Danhong injection for unstable angina (UA)after percutaneous coronary intervention in patients.Methods 180 patients with UA were ran-domly divided into two groups,and patients undergoing percutaneous coronary intervention (PCI)therapy.In addi-tion,90 cases in the control group were treated with conventional western medicine treatment,90 cases in the observa-tion group were treated with conventional western medicine treatment and Danhong injection therapy.The serum super-oxide dismutase (SOD),malondialdehyde (MDA)and brachial artery flow -mediated endothelium -dependent vaso-dilation (FMD),von Willebrand factor (vWF),plasma nitric oxide (NO),endothelin -1 (ET -1)levels and other indicators before and after treatment were detected.Results The total effective rate of the observation group was 96.67%,which was significantly higher than 75.56% of the control group (χ2 =9.23,P <0.05).The endothelial function parameters NO(73.66 ±11.58)μmol/L,ET -1 (64.75 ±6.83)ng/L,vWF(114.58 ±16.24)%,FMD (6.54 ±0.88)% of the observation group after treatment were significantly improved than before treatment (t =8.04,7.90,8.44,7.67,all P <0.05),which of the control group were (62.78 ±10.42)μmol/L,(92.31 ±8.67)ng/L, (152.64 ±18.75)%,(4.18 ±0.72)%,there were significant differences(t =6.78,7.34,7.70,6.56,all P <0.05).The serum SOD (154.62 ±21.37)U /mL and MDA (4.18 ±0.79)nmol/L levels of the observation group were significantly improved than before treatment(t =7.58,8.67,all P <0.05 ),which of the control group were (132.45 ±26.89)U /mL,(5.27 ±1.16)nmol/L,there were significant differences (t =7.22,7.81,all P <0.05). Conclusion Danhong injection for the treatment of UA stasis syndrome can be widely promoted by reducing oxidative stress on vascular endothelial damage,and improving endothelial function in patients after PCI,has great clinical value.

Objective To evaluate the vascular remodeling features in the elderly hypertensives through detecting the changes of large arterial structure and function by ultrasonography. Methods High resolution ultrasound was applied to examine 52 lightly or moderate elderly hypertensives(LMEH), 52 elderly normal subjects(EN) and 25 adult normal subjects(AN). Carotid and humeral arterial intimal-medial thickness (IMT), lumen diameter(r) and IMT/r were determined as the index for the changes of arterial structure, and the humeral arterial endothelium-dependent vasodilation and cross-sectional compliance were used to reflect the changes of arterial functions. Results Carotid IMT and lumen diameter were larger in LMEH group than those in EN group(0.97?0.21)% vs. (0.82?0.12)%, (7.41?2.13)% vs. (6.38?0.45)%, all P

OBJECTIVE: To explore the effects of Houttuynia Cordata on expression of human beta-defensin-2 (HBD-2) in pulmonary epithelial cells (SPC-A-1) in vitro; and to observe the correlationship between the level of HBD-2 mRNA and the concentrations or treatment times of Houttuynia Cordata. METHODS: The SPC-A-1 cells were cultured with different concentrations of Houttuynia Cordata in vitro, including 0, 12.5, 25, 50, 100 and 200 microg/ml. And then, the SPC-A-1 cells were cultured with the optimal concentration of Houttuynia Cordata in different lengths of time, including 1, 2, 4, 8, 16 and 24 hours. After the treatment, the mRNA level of HBD-2 in pulmonary epithelial cells was detected by means of semi-quantitative reverse transcription polymerase chain reaction (RT-PCR). RESULTS: After being cultured with Houttuynia Cordata, the expression of HBD-2 mRNA had positive correlation with the stimulus concentrations (rs=0.829, P=0.042) and stimulus time (rs=0.914, P=0.003). The highest expression of HBD-2 mRNA was induced by 100 microg/ml Houttuynia Cordata after 8-hour treatment. In comparison with the normal control group and the interleukin-1beta group, 100 microg/ml Houttuynia Cordata could significantly up-regulate the expression of HBD-2 mRNA in SPC-A-1 cells after 8-hour treatment (P<0.01). CONCLUSION: Houttuynia Cordata can up-regulate expression of HBD-2 mRNA in SPC-A-1 cells, and the highest expression level of HBD-2 mRNA can be obtained by culture with 100 microg/ml Houttuynia Cordata for 8 hours.

Objective To analyze inducing factors of acute left heart failure(AHF) of emergency case.Methods According to different age and gender,the inducing factors of AHF of 211 patients were retrospectively analyzed.Results Infection(42.99%) was the most important inducing factors of AHF in all the four age-groups,but as for patients elder 80,the arrhythmias was also play an important part in inducing factors of AHF.The difference of inducing factors was found among the four age-groups.but the difference of inducing factors was not found between the two gender-groups. Conclusion Since the most important inducing factors of AHF of emergency case was infection,anti-infectives is important for preventing and controlling AHF.

Objective · To determine the expression of miRNA-7 in TWEAK-stimulated macrophages and their secreted exosomes;to investigate the role of exosomal miRNA-7 from TWEAK-stimulated macrophages in modulating the metastasis of epithelial ovarian cancer (EOC) cells.Methods · Real-time PCR analysis was used to determine the miRNA-7 expression in TWEAK-stimulated macrophages,their exosomes and recipient HO8910-PM cells.The activity of EGFR signaling pathway in HO8910-PM cells was detected by Western blotting analysis.AntagomiR-7 was used to downregulate the miRNA-7expressions in macrophage exosomes and then their effect on metastasis of HO8910-PM cells was examined by transwell assay.Results ·TWEAK increased the levels of miRNA-7 in macrophages and their secreted exosomes and also resulted in an elevated level of miRNA-7 in recipient HO8910-PM cells,which eventually reduced the activity of EGFR/AKT/ERK1/2 pathway.Pre-transfection of antagomiR-7 remarkably decreased the levels of miRNA-7 in macrophages,their secreted exosomes and the recipient EOC cells,with the enhancement of HO8910-PM metastasis.Conclusion · Exosomal miRNA-7 from TWEAK-stimulated macrophages plays a critical role in suppressing the metastasis of EOC cells by attenuation of EGFR signaling pathway.
