RESUMEN
ObjectiveTo observe the clinical efficacy of the Modified Tongmai Anshen Formula (通脉安神方加减, MTAF) in the treatment of stable angina pectoris (SAP) with sleep disorders. MethodsA total of 148 patients suffering from SAP with sleep disorder were included and randomly divided into control group and treatment group, with 74 patients in each group. The control group received conventional western medicine, and the treatment group additionally received MTAF (1 dose per day), both for 4 weeks. The changes in angina pectoris symptoms, traditional Chinese medicine (TCM) syndromes, sleep quality, quality of life, serological indicators including serum intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1), brain-derived nerve growth factor (BDNF) and tyrosine kinase receptor B (TrkB) were compared between groups before and after treatment, and the safety was evaluated. ResultsIn the treatment group and the control group, the total effective rates of TCM syndromes(82.43% vs 52.70%), angina pectoris (79.73% vs 64.86%) and sleep (89.19% vs 68.92%) showing significant difference (P<0.001). After treatment, the total TCM syndrome score, primary symptom score, secondary symptom score, and secondary symptoms sleeplessness, restlessness, tiredness and fatigue individual score, angina pectoris score, PSQI total score and each item score were all significantly reduced in both groups, while the SF-36 single item score significantly increased (P<0.05). The total TCM syndromes and primary symptom scores, secon-dary symptoms sleeplessness, restlessness, tiredness and fatigue individual score, angina pectoris score, time to fall asleep, sleep quality, hypnotic medication, sleep disturbance, daytime dysfunction score and PSQI total score were significantly lower in the treatment group than those in the control group after treatment (P<0.05), while the somatic pain, general health status, social functioning, emotional functioning, mental health, and health change were significantly higher in the treatment group (P<0.05). After treatment, ICAM-1 and VCAM-1 level significantly decreased (P<0.05), and BDNF and TrkB levels increased (P<0.05) in the treatment group, while BDNF level significantly decreased in the control group (P<0.05). The TrkB level was significantly higher in the treatment group compared to the control group after treatment (P<0.05). A total of four adverse events occurred during the treatment, none of which were considered to be related to this study. ConclusionMTAF can significantly improve angina pectoris symptoms, TCM syndromes, sleep quality and quality of life in patients suffering from SAP with sleep disorders, the mechanism of which may be related to the protection of vascular endothelial function and central neurons.
RESUMEN
【Objective】 To investigate the association of platelet/albumin ratio (PAR), platelet/hemoglobin (PHR) and C-reactive protein/albumin (CAR) with diabetes mellitus. 【Methods】 Based on the data of China Health and Nutrition Survey (CHNS2009), with gender and age matched by their ID, a total of 8 258 individuals with serological test results were finally included and were divided into diabetes group and control group according to the fasting blood glucose and HbA1c, and then the blood lipid and blood cell changes, PAR, PHR and CAR differences between groups were compared, and the correlation analysis of diabetes was performed. 【Results】 Compared with those in the control group, serum uric acid, total cholesterol, triacylglycerol and low-density lipoprotein cholesterol (LDL-C) were significantly increased in diabetes group, while high-density lipoprotein cholesterol (HDL-C) was significantly decreased. Besides, there was no significant difference in PAR or PHR between the two groups, while CAR was significantly increased in diabetes (0.48±0.18 vs. 0.08±0.23, P<0.001), and was positively correlated with the levels of fasting glucose (r=0.181 8, P<0.001), HbA1c (r=0.186 6, P<0.001), and HOMA-IR (r=0.188 1, P=0.003). However, CAR was not an independent risk factor for diabetes. In addition, increased red blood cell count (B=1.324, 95% CI: 1.182-1.483, P<0.001) and leukocytes count (B=1.230, 95% CI: 1.166-1.298, P<0.001) may be independent risk factors for the incidence of diabetes. 【Conclusion】 CAR is correlated with diabetes mellitus, but it is not an independent risk factor. Dyslipidemia, elevated leukocytes and red blood cell counts may be independent risk factors for diabetes, but further study is needed.
RESUMEN
【Objective】 To explore the correlation of the intake of different nutrients with the levels of serum lipids and uric acid. 【Methods】 Based on the data of China Health and Nutrition Survey (CHNS2009), a total of 1 343 individuals were finally included by ID matching with demographic data, serological tests and dietary nutrition results. We compared serum lipids and uric acid levels between groups of different nutrients intake (group Q1-Q4) and conducted the correlation analysis. 【Results】 The total cholesterol (TC), triglyceride (TG), and low-density lipoprotein (LDL-C) in the men were significantly higher than those in the women, while high-density lipoprotein (HDL-C) was significantly lower in the men. The average intakes of daily energy, carbohydrate, fat and protein were significantly higher in the males than in the females. Intergroup comparisons and correlation analyses showed that total energy and protein intakes were positively correlated with TG (r=0.070 9,P=0.008 4;r=0.051 7,P=0.012 3), while fat intake was positively correlated with TC (r=0.086 1,P=0.001 4). The blood uric acid level was positively correlated with the intake of fat and protein (r=0.127 3,P<0.001;r=0.138 0,P<0.001). The results of subgroup analysis of the males were consistent with those of the whole population. However, there was a significantly negative correlation between carbohydrate intake and blood uric acid level in the females (r=-0.107 9,P=0.002 2). Multiple linear regression analysis showed that TC, TG and uric acid were correlated with gender, age and intake of different nutrients. 【Conclusion】 The levels of blood uric acid and lipids are significantly higher in men than in women. Different types of dyslipidemia and hyperuricemia are related to different nutrient intakes in different genders and ages.
RESUMEN
【Objective】 To explore the potential mechanism of Salvia miltiorrhiza and its active monomers in patients with coronary heart disease (CHD) complicated with depression or anxiety disorder based on network pharmacology. 【Methods】 We collected the clinical data of 147 patients with CHD admitted to our hospital from March to April 2021 and investigated biochemical examination, drug treatment and the use of Chinese herbal compound. The downstream targets of active monomers of Salvia miltiorrhiza were screened based on TCMSP, PubChem and SwissTargetPrediction databases, and depression or anxiety-related genes were mining in OMIM, GeneCards and TTD databases. Protein-protein interaction network and GO and KEGG gene enrichment analyses were performed by matching Chinese herbal compound with disease targets. Chinese herbal compound-target-disease network was built by Cytoscape. 【Results】 Shuxuening (44.9%), Salviae miltiorrhiza (27.9%), and Sofren injection (21.8%) were the most commonly used Chinese herbal or injections in the clinical treatment of CHD, and there was no difference in the frequency of use between genders. Network pharmacology showed that the active components of Salvia miltiorrhiza might act on neuroactive ligand-receptor binding, 5-hydroxytryptamine synapses and dopaminergic synapses and participate in the regulation of neurotransmitter transport, dopamine and catecholamine metabolism and stress response. Target-disease network analysis showed that many active components of Salvia miltiorrhiza interacted with catechol-O-methyltransferase, monoamine oxidase, 5-hydroxytryptamine receptor and opioid receptor, which may be the potential targets of Salvia miltiorrhiza in improving depression and anxiety. 【Conclusion】 Salvia miltiorrhiza is involved in the regulation of neurotransmitters and synaptic activities, thus making it a potential drug for the clinical treatment of CHD complicated with depression and anxiety disorder.
RESUMEN
【Objective】 To explore the correlation between serum trace elements and systolic and diastolic blood pressure in healthy population and patients with hypertension. 【Methods】 The health examination data of the subjects from our hospital from September 2018 to May 2021 were selected. They consisted of 3430 healthy people with no history of chronic diseases and 216 patients with hypertension previously diagnosed. We measured the levels of serum zinc, iron, calcium, magnesium, lead, copper and cadmium and analyzed their correlation with systolic blood pressure (SBP) and diastolic blood pressure (DBP). 【Results】 The incidence of low zinc (9.5%) and hypomagnesemia (1.8%) was relatively low, while hypomagnesemia (27.8%) was relatively common in the healthy population. Logistic regression analysis showed that age, BMI and serum albumin were associated with increased SBP and DBP. Fasting blood glucose (OR=1.095, 95% CI: 1.007-1.191) and blood lead (OR=1.006, 95% CI: 1.000-1.012) were risk factors for SBP. Serum total cholesterol (OR=1.244, 95% CI: 1.095-1.412), serum iron (OR=1.275, 95% CI: 1.114-1.460) and blood lead (OR=1.010, 95% CI: 1.004-1.015) were risk factors, while serum magnesium (OR=0.488, 95% CI: 0.266-0.894) acted as a protective factor for DBP. After adjusting for age, gender, BMI, waist-hip ratio, and smoking history, there was no significant difference in serum trace element levels between the hypertension and healthy control groups. 【Conclusion】 SBP is correlated with serum lead, while DBP is positively correlated with serum iron and lead, but negatively correlated with serum magnesium in normal healthy population. There was no significant difference in serum trace element content between hypertensive patients and healthy control group, but the conclusion still needs to be further verified.
RESUMEN
【Objective】 To investigate the inhibitory effect of magnesium citrate (MgCit) on hyperphosphorus-induced VSMCs calcification and its mechanisms. 【Methods】 VSMCs were divided into the following groups: normal control group, high-phosphorus group, low-dose MgCit group, high-dose MgCit group and high-dose MgCit+NPS2143 (calcium-sensitive receptor inhibitor) group. Alizarin red staining was used for semi-quantitative analysis of VSMCs calcification and the calcium content in VSMCs was detected by the commercial kit. The osteogenic transdifferentiation parameters including alkaline phosphatase (ALP) activity, as well as mRNA and protein levels of smooth muscle 22α (SM22α), runt-related transcription factor 2 (RUNX2) and bone morphogenetic protein 2 (BMP2), were detected in each group. 【Results】 Compared with those in the control group, the calcium content of VSMCs in the model group was increased, ALP activity, and the mRNA and protein expressions of RUNX2 and BMP2 were increased, and the mRNA expression of SM22α was decreased (P<0.05). MgCit could reduce VSMCs calcification, decrease ALP activity, decrease mRNA and protein levels of RUNX2 and BMP2, and increase mRNA levels of SM22α induced by high-phosphorous (P<0.05). The above effects of MgCit were reduced when NPS2143 was administered simultaneously (P<0.05). 【Conclusion】 MgCit can reduce VSMCs calcification and osteogenic transdifferentiation induced by high phosphorus through activating of CaSR.
RESUMEN
【Objective】 To investigate the negative emotions among university students during home quarantine under the epidemic of coronavirus disease 2019 (COVID-19) so as to provide scientific basis for psychological counseling. 【Methods】 We conducted an online questionnaire survey to collect 405 undergraduates’ and postgraduates’ DASS-21 scale scores and responses to epidemic prevention knowledge, and analyzed the university students’ negative emotions during the epidemic and influencing factors. 【Results】 Of the 405 students surveyed, 178 individuals (44.0%) had depression, 171(42.2%) felt anxious, and 119(29.4%) felt stressed. Individuals in the DASS21+ group spent much time on entertainment on the cell phone daily than those in the DASS21- group (P<0.001), and the degree of impact by COVID-19 on daily life was significantly higher (P<0.001). Correlation analysis showed that entertainment time on the cell phone, the severity of COVID-19, and the impact of the epidemic were positively related to DASS-21 scores, with correlation coefficients of 0.231, 0.143 and 0.259, respectively (all P<0.01). Binary logistic regression analysis found that mobile entertainment time for over 5 hours per day (OR=3.370, 95% CI: 1.369-8.294, P=0.008) was a risk factor for negative emotions during quarantine at home. 【Conclusion】 During quarantine at home in the epidemic of COVID-19, nearly half of university students are prone to breed negative emotions, like depression, anxiety or stress, which may be related to long-term mobile phone entertainment.
