Comprehensive Evaluation of the Nutritional Properties of Different Germplasms of Polygonatum cyrtonema Hua.

Polygonatum cyrtonema Hua, an edible resource and medical material, is mainly consumed as a food in China. However, few published studies have comprehensively assessed its nutritional components. In this study, the proximate, carbohydrate, and dietary fiber contents as well as the mineral, vitamin, and amino acid compositions of five sources of P. cyrtomena grown in Yuhang district, Hangzhou city, Zhejiang province, were investigated. The nutritional profile of the five germplasms was investigated using analytical chemistry methods. All germplasms had a low starch content and contained greater amounts of carbohydrates (23.25-34.29%), protein (2.96-5.40%), Ca (195.08-282.08 mg/100 g), Fe (29.68-59.37 mg/100 g), and vitamin C (60.49-149.86 mg/100 g) in comparison to ginger, yam, and potatoes. The polysaccharide content ranged from 16.92% to 28.48%, representing the main source of carbohydrates. Fructose, a desirable sweetener, was the most abundant monosaccharide, representing 1.06% to 4.88% of the content. P. cyrtonema was found to be high in dietary fiber, with pectin and resistant starch being the major soluble components and hemicellulose being the dominant insoluble dietary fiber. A correlation analysis (CA) revealed significant correlations for the carbohydrate components and dietary fiber fractions with other nutrients. A principal component analysis (PCA) identified significant differences between the nutritional characteristics of the five germplasms, with Huanggang having the highest comprehensive quality scores. Moreover, ten nutrient components were selected as potential indicators that could be used to further evaluate the nutritional quality of P. cyrtomena. Our results demonstrate the rich nutrient composition and characteristics of P. cyrtonema and provide a valuable reference for the future development and utilization of Polygonatum.

Clinical significance of N-terminal natriuretic peptide combined with inflammatory factors, oxidative stress factors and blood lipid detection in elderly patients with Type-2 diabetes complicated with coronary heart disease.

Objectives: To observe the clinical significance of N-terminal natriuretic peptide combined with inflammatory factors, oxidative stress factors and blood lipid detection in elderly patients with Type-2 diabetes complicated with CHD (CHD), and provide a theoretical basis for the diagnosis and treatment of elderly patients with Type-2 diabetes complicated with CHD. Methods: A total of 40 patients with Type-2 diabetes complicated with CHD admitted to Affiliated Hospital of Hebei University from July 2019 and July 2020 were selected as the experimental group, and 40 patients with CHD who were hospitalized in our hospital during the same period without diabetes were selected as the control group. Venous blood was taken from all patients on morning and fasting basis, and their serum inflammatory factors as well as antioxidant molecules were examined respectively. Serum inflammatory factors include serum tumor necrosis factor α (TNF-A), interleukin-6 (IL-6), and C-reactive protein. Antioxidant molecules include antioxidant molecules superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), total antioxidant capacity (TAC), catalase (CAT), glutathione reductase (GR), N-terminal natriuretic peptide (NT-proBNP), white blood cells (WBC), hemoglobin (HBG), albumin (ALB) and blood lipid levels. The differences of the above indexes between experimental group and control group were compared and analyzed. Results: The serum levels of TNF-a, CRP, and IL-6 in the experimental group were apparently higher than those in the control group, with a statistically significant difference (P=0.00); The levels of SOD, TAC and CAT in the experimental group were significantly lower than those in the control group, with a statistically significant difference (P=0.00); The level of NT-proBNP and WBC count in the experimental group were significantly higher than those in the control group, with a statistically significant difference (NT-proBNP, P=0.01; WBC, P=0.00). However, no statistically significant difference was observed in the levels of HBG and ALB between the two groups (P>0.05). The experimental group had significantly higher TC and TG levels than the control group, with statistically significant differences (TC, P=0.01; TG, P=0.02), but had a significantly lower HDL level than the control group, with a statistically significant difference (P=0.00). Conclusion: Elderly patients with Type-2 diabetes complicated with CHD showed systemic microinflammation, decreased antioxidant molecule content, as well as myocardial damage and abnormal lipid metabolism compared with patients with CHD alone. For this reason, attention should be paid to the above risk factors in clinical practice, and proactive prevention and treatment should be taken to reduce the probability of related complications.

Effect of Tirofiban Injection on vascular endothelial function, cardiac function and inflammatory cytokines in patients with acute myocardial infarction after emergency Percutaneous Coronary Intervention.

OBJECTIVES: To evaluate the effect of tirofiban injection on vascular endothelial function, cardiac function, inflammatory cytokines and other indicators in patients with acute myocardial infarction after emergency PCI and its clinical significance. METHODS: Eighty patients with acute myocardial infarction admitted to Affiliated Hospital of Hebei University from March 18, 2020 to October 18, 2020 were enrolled and randomly divided into two groups: the experimental group and the control group, with 40 cases in each group. Patients in both groups underwent PCI. Patients in the control group were given oxygen inhalation, monitoring, and basic medications for myocardial infarction, such as nutritional myocardial drugs, statins, aspirin, nitrates, clopidogrel, and ß-blockers. In contrast, patients in the experimental group received tirofiban 10 ug/kg intravenously over 5min immediately before PCI in addition to basic treatment, and then tirofiban 0.1 ug/(kg/min) was pumped via intravenous pump postoperatively for 48 hour. The changes of vascular endothelial function, cardiac function and adverse drug reactions (ADRs) in the two groups before treatment, one week and one month after treatment, as well as changes of inflammatory cytokines such as CRP and IL-6 in the two groups before and after treatment were compared and analyzed. RESULTS: Compared with the control group, FMD, NO, ET-1 and other indexes in the experimental group were significantly improved one week and one month after treatment, with statistically significant differences (p<0.05). BNP, LVEDD, LVEF and additional indexes in the experimental group were significantly lower than those in the control group at one week and one month after treatment, with statistically significant differences (p=0.00). Moreover, the incidence of ST-segment fallback > 70% in the experimental group was 72.5% after treatment, which was significantly better than that of 47.5% in the control group, with a statistically significant difference (p=0.03). CRP and IL-6 in the experimental group were significantly lower than those in the control group after treatment, with a statistically significant difference (p=0.00). There was no statistical significance in the incidence of ADRs between the two groups after treatment (p=0.42). CONCLUSION: Tirofiban injection after emergency PCI is a beneficial treatment regime for patients with STEMI. With such a treatment regime, cardiac function and vascular endothelial function of patients can be dramatically improved, coronary blood supply will be ameliorated, inflammatory cytokines can be reduced, and no significant increase can be seen in the incidence of adverse reactions.

Etiology Exploration of Non-alcoholic Fatty Liver Disease From Traditional Chinese Medicine Constitution Perspective: A Cross-Sectional Study.

Background: From the traditional Chinese medicine (TCM) constitution theory perspective, the phlegm-dampness constitution is thought to be closely related to the occurrence of non-alcoholic fatty liver disease (NAFLD). However, this viewpoint still lacks rigorous statistical evidence. This study aimed to test the association between the phlegm-dampness constitution and NAFLD. Methods: We conducted a cross-sectional study. Participants were residents living in Chengdu, China, undergoing health checkups at the health management center of Affiliated Hospital of Chengdu University of Traditional Chinese Medicine between December 2018 and September 2020. TCM constitution type was diagnosed by DAOSH four examinations instrument, NAFLD was diagnosed according to the liver ultrasonography and medical history. Multivariate logistic regression and propensity score matching (PSM) were used to analyze a total of 1,677 qualified data. Results: 1,037 participants had biased constitution(s), 67.8% of which had mixed constitutions (with at least two constitutions). Among 1,677 participants, the phlegm-dampness constitution was associated with the yang-deficiency, yin-deficiency, dampness-heat, qi-depression, and blood-stasis constitutions. The correlation coefficients were 0.11, 0.32, 0.42, 0.20, 0.14, respectively. Between the phlegm-dampness constitution and NAFLD, the odds ratio (OR) and the 95% confidence interval (CI) was 2.05 (1.57-2.69) in the crude model. After adjusting for age, gender, Body mass index (BMI), other biased constitutions, smoking, high blood pressure, diabetes, and dyslipidemia, the OR reduced to 1.51 (1.04-2.18). The associations of seven other biased TCM constitutions and NAFLD were not statistically significant in the fully adjusted model. The PSM analysis showed consistent results with the logistic regression. Conclusions: Among eight biased TCM constitutions, the phlegm-dampness constitution is independently associated with NAFLD. We speculate the phlegm-dampness constitution is a risk factor of NAFLD. Longitudinal studies are needed to confirm this causal relationship in the future. In addition, inconsistent with some TCM practitioners' experience, we disagree that the blood-stasis constitution is associated with NAFLD.

Traditional Chinese medicine fumigation as auxiliary treatment of diabetic peripheral neuropathy: A protocol for systematic review and meta-analysis.

BACKGROUND: Diabetic peripheral neuropathy (DPN) is 1 of the most common clinical complications of diabetes, which seriously affects the quality of life of patients and causes a substantial economic burden on diabetes care. The pathogenesis of DPN is complex. There is no targeted treatment method, and mainstream treatment methods have low efficacy and large side effects. Traditional Chinese medicine has rich clinical experience in the prevention and treatment of diabetic peripheral neuropathy, which has dramatically improved the quality of life of patients. It is clinically proven that traditional Chinese medicine fumigants (TCMF) have apparent effects in treating diabetic peripheral neuropathy. Therefore, we aim to systematically review the effectiveness and safety of TCMF for DPN. METHODS: We will search the following databases: PubMed, Embase, Cochrane Library, MEDLINE, the China National Knowledge Infrastructure, the Chinese Biomedical Literature Database, Cqvip Database, and Wanfang Data. Besides, we will also search for clinical trial registrations, potential grey literature, relevant conference abstracts, and reference lists of established studies. The studies published from the inception of the database to November 2020 will be retrieved. The randomized controlled trials on TCMF for DPN will be included. Also, we will search for clinical trial registrations, potential grey literature, relevant conference abstracts, and reference lists of established studies. The main result is clinical efficacy and nerve conduction velocity. Fasting blood glucose, 2 hours postprandial blood glucose, blood lipid, glycosylated hemoglobin, and adverse events are secondary results. We will perform the analyses using RevMan V.5.3 software. RESULTS: This study will provide a high-quality comprehensive evaluation of the efficacy and safety of TCMF in the treatment of DPN. CONCLUSIONS: This systematic review will evaluate the effectiveness and safety of TCMF in the treatment of DPN, and provide the latest evidence for clinical application.
