ABSTRACT
Objective:To study the effects of sacubitril valsartan sodium on vascular sclerosis and ventricular remodeling in patients with ischemic cardiomyopathical coronary heart disease.Methods:A prospective research method was adopted. One hundred and eighty-six patients with coronary heart disease who were treated in Hangzhou Ninth People′s Hospital from January to December 2021 were selected and divided into control group and observation group by random digits table method, with 93 cases in each group. The control group adopted routine treatment method of aspirin + metoprolol + nitroglycerin + captopril according to the guideline, while the observation group was additionally treated with sacubitril valsartan sodium on the basis of the control group. The clinical efficacy, vascular endothelial function and hardness, cardiac function, ventricular remodeling and adverse reactions were compared between the two groups.Results:The total effective rate of treatment in observation group was significantly higher than that in control group: 96.77%(90/93) vs. 87.10%(81/93), and there was statistical difference ( P<0.05). After treatment, the brachial artery flow-mediated dilation in observation group was significantly higher than that in control group: (14.46 ± 2.80)% vs. (13.09 ± 2.74)%, the level of endothelin-1 was significantly lower than that in control group: (73.32 ± 9.63) ng/L vs. (77.47 ± 10.35) ng/L, and there were statistical differences ( P<0.05). After treatment, the left ventricular ejection fraction (LVEF) in observation group was significantly higher than that in control group: (50.87 ± 3.52)% vs. (49.72 ± 3.71)%, the left ventricular end-systolic diameter, left ventricular end-diastolic diameter and ventricular remodeling indicators of interventricular septal thickness and left ventricular mass index were significantly lower than those in control group: (38.26 ± 5.18) mm vs. (40.05 ± 5.20) mm, (50.49 ± 4.33) mm vs. (52.08 ± 4.25) mm, (8.95 ± 0.39) mm vs. (9.08 ± 0.41) mm, (118.49 ± 9.58) g/m 2 vs. (121.58 ± 9.62) g/m 2, and there were statistical differences ( P<0.05). There were no statistical differences in the levels of total cholesterol, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol after treatment between the two groups ( P>0.05). There were no statistical differences in the incidences of adverse reactions between the two groups ( P>0.05). Conclusions:Sacubitril valsartan sodium has a good clinical efficacy in the treatment of coronary heart disease, and it can improve cardiac function and vascular sclerosis and reverse ventricular remodeling. In addition, it has no significant adverse reactions and is conducive to disease recovery.
ABSTRACT
As the nerve regeneration has been researched more and more, nerve regeneration related signaling pathways after spinal cord injury (SCI) comes into the view. Inhibiting apoptosis signaling pathways may reduce the apoptosis, inflammation and nerve degenera-tion after SCI. Mitogen activated protein kinase (MAPK) signaling pathway plays an important role in regulation of gene expression, cell proliferation and apoptosis, and there was interaction among the four subordinate pathways. Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway does not only participate in the body cell survival, proliferation, differentiation and apoptosis, but also in the process of inflammatory and oxidative stress in the body. It has been found that blocking the Wnt signaling pathway after inju-ry in the central nervous system would inhibit neural axon regeneration. Exogenous Wnt3a can increase the number of neurons after SCI and promote the axon conduction and nerve function. Inhibiting mammalian target of rapamycin (mTOR) signaling pathway after SCI can signif-icantly reduce neuronal loss, cell death and well promote the functional recovery. When Notch signaling pathways are activated, neural stem cells proliferate actively and differentiation are inhibited, and stem cells enter the stage of differentiation as the pathway inhibited. Activa-tion of Ras homolog gene/Rho associated coiled coil forming protein kinase (Rho/ROCK) signaling pathways leads to the collapse of the growth cone, inhibition of axon regeneration, whereas the selective inhibition of Rho can promote axon regeneration and recovery of motor function after SCI.
ABSTRACT
@#Objective To explore the effect of Governor Vessel electroacupuncture in different time points on motor function and p75 neurotrophin receptor (p75NTR) after spinal cord injury. Methods A total of 180 adult male Sprague-Dawley rats were randomly divided into three groups (one day, three days and seven days after modeling), and each group was divided into normal control group, normal electroacupuncture group, sham operation group, model group and Governor Vessel electroacupuncture group with 12 cases in each group. The spinal cord injury model was established with the modified Allen's method. The normal electroacupuncture group and the Governor Vessel electroacupuncture group received electroacupuncture on Dazhui (DU14) and Mingmeng (DU04) acupoints. Basso-Beattic-Bresnahan (BBB) Scale was performed to assess the motor function of rats. The expression of p75NTR was detected with Western blotting. Results The BBB score of the model group and the Governor Vessel electroacupuncture group were significantly lower than that of the other three groups. The BBB score was significantly higher in the Governor Vessel electroacupuncture group than in the model group seven days after intervention (t=-4.510, P<0.001). The expression of p75NTR was siginificantly lower in the Governor Vessel electroacupuncture group than in the model group (P<0.01). Conclusion The expression of p75NTR increased after spinal cord injury. Governor Vessel electroacupuncture could improve the motor function, and inhibit the p75NTR expression of damaged spinal cord tissues.
ABSTRACT
@#Spinal cord injury is a kind of central nervous system diseases with high morbidity. Acupuncture and moxibustion has unique advantages in treating spinal cord injury and its complications including neurogenic bladder, neuropathic pain, intestinal disorders, and muscle spasms. This article reviewed the researches of acupuncture and moxibustion treatment on spinal cord injury. It is presented to provide reference for clinical research.
