ObjectiveTo observe the effect of Jiawei Shenqi Yixin prescription on cardiovascular risk factors in the patients with heart failure with preserved ejection fraction and insulin resistance. MethodFrom January 2021 to January 2022, a total of 82 patients with heart failure with preserved ejection fraction were enrolled in the ward of the First Affiliated Hospital of Heilongjiang University of Chinese Medicine. The patients were randomly assigned into two groups ( 41 cases) and received the same basic treatment. The observation group was additionally treated with Jiawei Shenqi Yixin prescription for 8 weeks. The clinical efficacy, traditional Chinese medicine (TCM) efficacy, cardiac function indexes [NT-probrain natriuretic peptide (NT-proBNP) and 6-min walking test (6MWT)], echocardiographic parameters [left atrial volume index (LAVI), left ventricular mass index (LVMI), peak early diastolic to peak late diastolic mitral flow velocity (E/A) ratio], insulin resistance-related indexes [fasting insulin (FINS), fasting plasma glucose (FPG), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), homeostatic model assessment of insulin resistance (HOMA-IR), triglyceride-glucose index (TYG), and triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) ratio], inflammatory cytokines [tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), adiponectin (ADP), and C-reactive protein (CRP)], vascular endothelial function indicators [nitric oxide (NO), endothelial nitric oxide synthase (eNOS), inducible nitric oxide synthase (iNOS), and endothelin-1 (ET-1)], and the safety of treatment were determined. In addition, Pearson correlation analysis was performed to analyze the correlations of insulin resistance, inflammatory cytokines, and vascular endothelial factors with the mitigation of heart failure. ResultIn terms of clinical efficacy, the therapy of the observation group was significantly effective in 26 patients, effective in 12 patients, ineffective in 3 patients, with the total effective rate of 92.68%, the therapy of the control group was significantly effective in 14 patients, effective in 12 patients, and ineffective in 15 patients, with the total effective rate of 63.41%. The clinical total effective rate of the observation group was higher than that of the control group (χ2=11.6, P<0.05). In terms of TCM efficacy, the therapy of the observation group was significantly effective in 26 patients, effective in 11 patients, and ineffective in 4 patients, with the total effective rate of 90.24%; the therapy of the control group was significantly effective in 9 patients, effective in 13 patients, and ineffective in 19 patients, with the total effective rate of 53.66%. The TCM total effective rate of the observation group was higher than that of the control group (χ2=8.19, P<0.05). Compared with those before treatment, the levels of NT-proBNP, LAVI, LVMI, FPG, FINS, HOMA-IR, TYG, TG/HDL-C, TNF-α, IL-6, CRP, ET-1, and iNOS in two groups declined after treatment (P<0.05), while the levels of 6MWT, E/A, ADP, NO, and eNOS elevated (P<0.05). After treatment, the observation group had lower levels of NT-proBNP, LAVI, LVMI, FPG, FINS, HOMA-IR, TYG, TG/HDL-C, TNF-α, CRP, and ET-1 (P<0.05) and higher levels of 6MWT, E/A, ADP, and NO than the control group (P<0.05). In addition, the increase in 6MWT after treatment was positively correlated with the increase in NO and the decrease in ET-1. The decrease in LVMI after treatment was positively correlated with the increase in NO and the decrease in FINS. The increase in left ventricular ejection fraction after treatment was positively correlated with the decreases in TNF-α and TYG (P<0.05). Adverse reactions were observed in neither group. ConclusionJiawei Shenqi Yixin prescription can significantly mitigate the symptoms, reduce inflammation, and improve vascular endothelial function in the patients with heart failure with preserved ejection fraction and insulin resistance, being safe without causing adverse reactions.

This study analyzed the inherent relation between arterial blood mass flow and muscle atrophy of residual limb to provide some necessary information and theoretical support for the clinical rehabilitation of lower limb amputees. Three-dimensional arterial model reconstruction was performed on both intact side and residual limb of a unilateral transfemoral amputee who is the subject. Then hemodynamic calculation was carried out to comparatively analyze the mass flow state at each arterial outlet of both lower extremities. The muscle atrophy ratio of residual limb was calculated by measuring the cross-sectional area of bilateral muscles. Based on the blood supply relationship, the correlation between arterial blood flow reduction ratio and muscle atrophy ratio was discussed. The results showed that the mass flow of superficial femoral arteries and lateral circumflex femoral arteries severely reduced. Meanwhile rectus femoris, vastus lateralis and vastus medialis which were fed by these arteries showed great atrophy too. On the contrary, the mass flow of deep femoral arteries and medial femoral circumflex arteries slightly reduced. Meanwhile gracilis, adductor longus, long head of biceps which were fed by these arteries showed mild atrophy too. These results indicated that there might be a positive and promotion correlation between the muscle atrophy ratio and the blood mass flow reduction ratio of residual limb during rehabilitation.
