ABSTRACT

ObjectiveTo summarize the thinking of treatment of headache based on syndrome differentiation by reviewing the literature of materia medica in the past dynasties, so as to guide the clinical practice. MethodAll the literature of materia medica in the Chinese Medical Dictionary, involving 76 works from Han to Qing Dynasties, were searched, and the information of the herbs for treating headache was extracted. According to Chinese Materia Medica (11th Edition) and Pharmacopoeia of the People's Republic of China (2020 Edition), the nature, taste, and meridian tropism of the selected herbs were statistically analyzed, and the syndrome elements of headache were classified and counted. In addition, the contents of syndrome differentiation and treatment of headache by different herbs were extracted. ResultFrom the 76 monographs of materia medica in the past dynasties, 114 herbs for treating headache were selected. The herbs mainly had cold or warm nature, pungent or bitter taste, and tropism to the lung and live meridians. The syndrome elements of headache treated by the herbs mainly included wind attack, fire disturbance, turbid obstruction, stagnation, cold coagulation, and healthy Qi deficiency. ConclusionHeadache is mainly treated with the herbs with the effects of dispelling pathogenic wind, clearing heat and purging fire, eliminating phlegm and resolving dampness, regulating Qi movement and activating blood, warming Yang and dispelling cold, and tonifying deficiency and reinforcing healthy Qi, and the herbs are often used in combinations. Headache is treated following the principles of dispelling wind and pathogen, regulating Qi and blood, and tonifying deficiency and purging excess, which is in line with the laws of obstruction and nutrient deficiency causing pain.

ABSTRACT

In recent years, with the development of metabolic reprogramming research, people have changed their understanding of the biological effects of immune cells. Under the stimulation of inflammatory response, immune cells re-regulate their metabolism and bioenergetics, provide energy and substrates for cell survival, and initiate immune effect functions. Nod-like receptor protein 3 (NLRP3) inflammasome, as an important component of the innate immune system, has been shown to sense metabolites such as uric acid and cholesterol crystals, and can be inhibited by metabolites such as ketones. It is also regulated by mitochondrial reactive oxygen species and glycolytic components (such as hexokinase). Recent studies have shown that a variety of metabolic pathways converge as effective regulators of NLRP3 inflammasome. The paper reviews the metabolic regulatory pathways and specificity of NLRP3 inflammasome activation, and its role in renal diseases.

ABSTRACT

Objective:To investigate the regional homogeneity (ReHo) among the major depressive disorder patients without mixed features (MDD noMF), major depressive disorder with mixed features (MMF), bipolar disorder with mixed features (BMF) and bipolar disorder patients without mixed features (BD noMF) patients, and to explore the brain activity and functional connectivity patterns of the MMF and BMF patients. Methods:This was a cross-sectional study. The MDD noMF patients (MDD noMF group), MMF patients (MMF group), BMF patients (BMF group), BD noMF patients (BD noMF group), and age-and gender-matched healthy controls (HC group) were recruited from Beijing Anding Hospital, Capital Medical University between April, 2021 and June, 2022. All the participants underwent resting-state functional MRI scanning. The ReHo values was computed with the DPABI software based on the MATLAB. Firstly, the difference in ReHo among the patients with MDD noMF, MMF, BMF, BD noMF and HC group were estimated by the analysis of covariance and the post-hoc method (LSD or Games-Howell). And then, the brain regions with significant different ReHo values were selected as the seeds to calculate the functional connectivity with the whole brain. Results:A total of 29 cases in the MDD noMF group, 24 cases in the MMF group, 26 cases in the BMF group, 29 cases in the BD noMF group, and 42 in the HC group were included. The differences in ReHo values in the left fusiform and the left precuneus of the 5 groups were statistically significant ( P<0.05). Among of them, the ReHo values of the left fusiform were lower in the MMF, BMF and BD noMF groups compared with the HC group ( P<0.05), while the ReHo values of the left precuneus in MDD noMF, MMF, BMF and BD noMF groups were higher than that in the HC group ( P<0.05). The ReHo value of the left fusiform was lower in the MMF group compared with the MDD noMF group ( P=0.001); the ReHo value of the left fusiform was lower in the BMF group compared with the MDD noMF and BD noMF groups ( P<0.05). The functional connectivity between the left fusiform and vermis, left insula, right putamen, and left medial superior frontal gyrus, and functional connectivity between the left precuneus and right superior frontal gyrus (dorsolateral) showed significant difference among the MDD noMF, MMF, BMF, BD noMF and HC groups ( P<0.05). Compared with HC group, MDD noMF, MMF, BD noMF groups showed higher functional connectivity between the left fusiform and the vermis, and MDD noMF, MMF, BMF, BD noMF group showed higher functional connectivityy between the the left fusiform and the left insula, left medial superior frontal gyrus and right putamen ( P<0.05). Compared with the MDD noMF group, the MMF, BMF and BD noMF groups showed higher functional connectivity between the left fusiform and the left insula ( P<0.05). Compared with the MDD noMF group, the BMF and BD noMF groups had higher functional connectivity between the left fusiform and the left medial superior frontal gyrus ( P<0.05). The BMF group showed higher functional connectivity of the left fusiform with the right putamen than the MDD noMF and BD noMF groups. Additonally, the BMF and BD noMF groups showed higher functional connectivity between the left precuneus and the right superior frontal gyrus (dorsolateral) than HC, MDD noMF and MMF groups ( P<0.05). Conclusions:MMF and BMF patients have local abnormalities of functional activity synchronization in the left fusiform and precuneus and abnormal functional connectivity patterns with multiple brain regions. MMF and BMF patients have specific neuroimaging features compared to MDD noMF or BD noMF patients and also share similar neuroimaging pathogenesis.

ABSTRACT

Objective:To investigate the relationship between n7-methylguanosine (m7G) related long non-coding RNA (lncRNA) expression and glioma prognosis, and to construct a prognosis model with m7G-related lncRNA in patients with glioma.Methods:Data related to the test set and validation set were downloaded from the Cancer and Tumor Genome Atlas (TCGA) database and the China Glioma Genome Atlas (CGGA) database. LASSO regression and random forest algorithm were used to establish the glioma prognosis model with m7G related lncRNA. Individualized risk scores were calculated using the weighted expression levels of the 12 extracted lncRNA coefficients, and test set and validation set glioma patients were categorized into high and low risk groups based on median risk score. Kaplan-Meier survival curve was drawn, the comparison method used log rank test. The efficacy of risk score in predicting the 1-, 2- and 5-year survival rate in patients with glioma was evaluated using the receiver operating characteristics (ROC) curve.Results:A total of 12 lncRNA associated with m7G were obtained, with a risk score = 1.026 × AC002454.1 + 1.086 × AC131097.4 + 1.039 × AC147651.3 + 1.01 × AGAP2-AS1 + 1.036 × CRNDE + 0.733 × GDNF-AS1 + 1.321 × HOXD-AS2 + 0.934 × LINC00641 + 1.183 × PAXIP1-AS2 + 1.258 × PVT1 + 0.909 × SOX21-AS1 + 0.754 × TTC28-AS1, with a median risk score of - 0.45 scores. Kaplan-Meier survival curve analysis result showed that the median survival time in high risk group was significantly shorter than that in low risk group (1.98 years vs. 9.51 years, log-rank χ2 = 131.78, P<0.01). ROC curve analysis result showed that the area under the curve (AUC) of risk score in predicting the 1-, 2- and 5-year survival rate in patients with glioma was 0.891, 0.923 and 0.912. In the validation set of glioma patients, Kaplan-Meier survival curve analysis result showed that the median survival time in high risk group was significantly shorter than that in low risk group (1.29 years vs. 6.88 years, log-rank χ2 = 103.27, P<0.01); ROC curve analysis result showed that the AUC of risk score in predicting the 1-, 2- and 5-year survival rate in patients with glioma was 0.724, 0.795 and 0.762. In the test set and validation set, multivariate Cox regression analysis result showed that the risk score was the independent risk factors of prognosis in patients with glioma ( HR = 1.992 and 1.247, P<0.01 or <0.05). Conclusions:A risk score model with m7G related lncRNA based on transcriptome is a novel approach to predict the prognosis of glioma patients.

ABSTRACT

As the overweight and obese population is growing, the incidence of obstructive sleep apnea is rising, and most of the cases are complicated with coronary heart disease and other cardiovascular diseases. The two diseases affect each other and seriously endanger the patients' health, becoming a major public health problem of global concern. It is of great clinical importance to explore the combination of Chinese and Western medicine in the prevention and treatment of coronary heart disease complicated with obstructive sleep apnea syndrome. Researchers have explored the relationship between the two based on traditional Chinese medicine(TCM) theory and found that the two diseases belong to the TCM disease categories of chest impediment and snoring, respectively, and their co-morbidity is associated with the abnormal physiological functions of the heart and lungs. The failure of the heart to govern blood leads to the generation of blood stasis, and that of the lung to govern Qi movement leads to the generation of phlegm. The accumulation of phlegm and blood stasis in the chest causes chest impediment and snoring due to obstruction of the airway. This paper discusses the internal linkage between the pathogenesis of coronary heart disease and obstructive sleep apnea syndrome in Chinese and Western medicine from the TCM theory of heart-lung correlation. Furthermore, this paper proposes the treatment principles of simultaneously treating the heart and lung and activating blood and resolving phlegm, aiming to provide a theoretical basis for the clinical prevention and treatment of coronary heart disease complicated with obstructive sleep apnea.

ABSTRACT

As the guiding theory for the diagnosis and treatment of encephalopathy in traditional Chinese medicine (TCM), The marrow sea theory has important theoretical connotation and clinical value. This paper summarized the clinical research literature on the differentiation and treatment of common encephalopathy based on the marrow sea theory published in recent years, analyzed the treatment method and effects from eight aspects in terms of stroke, dizziness, insomnia, headache, constraint syndrome, dementia, tremor syndrome, and atrophy syndrome, and discussed the possible mechanism based on the relevant basic research. It is believed that marrow sea depletion is the common pathogenesis of encephalopathy in TCM. Guided by the method of supplementing essence and boosting marrow, the corresponding formulas and medicinals are recommended in accordance with differentiated syndromes, which can effectively improve the symptoms of the disease, delay the progression, increase the daily life ability of the patients, and improve the quality of life. Based on the marrow sea theory, the method of supplementing essence and boosting marrow, rectifying healthy qi and dispelling pathogen can be used to highlight the advantages of TCM and provide ideas for the diagnosis and treatment of encephalopathy in TCM.

ABSTRACT

Vascular complications are the primary cause of the high disability and mortality in diabetic patients. Vascular calcification is a pathological basis of diabetic vascular complications and increases the risk of adverse cardiovascular events and the difficulty of revascularization in diabetic patients. It is of great clinical value to explore the measures for prevention and treatment of diabetic vascular calcification with integrated traditional Chinese and Western medicine. This paper explores the intrinsic association of stasis, toxin, and deficiency with diabetic vascular calcification to reveal the pathogenesis of diabetic vascular calcification. Stasis and toxin are causally affected by and combined with each other; deficiency refers to the deficiency of healthy Qi and the loss of Qi and blood. The three elements are associated with the occurrence and development of blood vessel diseases. This paper proposes the evolutional law of stasis, toxin, and deficiency in traditional Chinese medicine (TCM) for diabetic vascular calcification. Specifically, diabetic vascular calcification is rooted in the stasis of meridians and collaterals, develops due to the combination of stasis and toxin, and is aggravated by middle Qi deficiency. Furthermore, this paper proposes the TCM intervention principle of activating blood, removing toxin, tonifying deficiency, and dredging collaterals for the prevention and treatment of diabetic vascular calcification. The aim is to provide a theoretical basis for clinical and translational research on the prevention and treatment of diabetic vascular calcification with integrated Chinese and Western medicine.

ABSTRACT

ObjectiveTo screen and establish animal models of combined stasis and toxin syndrome based on the comparison of three modeling methods, i.e., carrageenan (Ca), Ca combined with dried yeast (Ca+Yeast), and Ca combined with lipopolysaccharide (Ca+LPS). MethodForty SPF male SD rats were randomly divided into normal group, Ca group, Ca+Yeast group, and Ca+LPS group, with 10 rats in each group. The Ca group, Ca+Yeast group, and Ca+LPS group received an intraperitoneal injection of Ca (10 mg·kg-1) on the first day. The Ca+LPS group received an intraperitoneal injection of LPS (50 μg·kg-1) on the second day, and the Ca+Yeast group received a subcutaneous injection of dry yeast suspension (2 mg·kg-1) on the back on the second day. The rectal temperature of each group was dynamically observed after modeling. After 24 hours of modeling, the macroscopic evaluation indexes, including tongue manifestation, pulse, and black tail length in each group were observed. The PeriCam PSI imaging system was used to detect the blood flow perfusion of the rat tail. The automatic hemorheology analyzer was used to measure the whole blood viscosity and plasma viscosity of each group. The PL platelet function analyzer was used to detect the platelet aggregation rate of the rats. The enzyme-linked immunosorbent assay (ELISA) was used to detect the interleukin-6 (IL-6) level in the rat plasma. The myocardial tissue, brain tissue, and lung tissue of each group of rats were observed by hematoxylin-eosin (HE) staining. ResultCompared with the normal group, all three model groups showed varying degrees of black tail (P<0.05, P<0.01), reduced blood flow perfusion at the tail end (P<0.05, P<0.01), decreased R, G, and B values of tongue manifestation (P<0.05, P<0.01), and increased maximum platelet aggregation rate (P<0.05, P<0.01). The pulse amplitudes of the Ca+Yeast group and the Ca+LPS group were lower than that of the normal group (P<0.05, P<0.01). In addition, the average rectal temperature of the Ca+Yeast group increased after 24 hours of modeling (P<0.01), and the low-, medium-, and high-shear whole blood viscosity and plasma viscosity increased (P<0.05, P<0.01) as compared with those in the normal group. Additionally, the expression level of the plasma inflammatory factor IL-6 was significantly up-regulated (P<0.05). Pathological morphology results showed that the Ca+Yeast group had the most severe pathological changes, with small foci of myocardial fiber dissolution, inflammatory cell infiltration, and fibroblast proliferation observed. In the hippocampal area, the neurons were sparse and had undergone red degeneration. In the small focus of the lung interstitium, lymphocytes and neutrophils were infiltrated. ConclusionThe animal model of combined stasis and toxin syndrome was properly established using Ca+Yeast. The systematic evaluation system of the model, which includes traditional Chinese medicine four diagnostic information, western medicine microscopic indicators, and tissue pathological morphology, is worthy of consideration and reference by researchers.

ABSTRACT

ObjectiveTo discuss the thought of treatment of orifices in the Chinese herbal classics in the past dynasties based on the correspondence between drugs and symptoms to guide the clinical treatment based on syndrome differentiation. MethodAll the literature data of Chinese herbal classics were retrieved from the database of the Chinese Medical Dictionary, involving 76 works of Chinese herbal classics and covering representative works from the Han dynasty to the Ming and Qing dynasties. The information on Chines herbal drugs for the treatment of orifices was collected and sorted out. According to Chinese Materia Medica (11th Edition) and Pharmacopoeia of the People's Republic of China (2020 Edition), the nature, flavor, and meridian tropism of the selected Chinese herbal drugs were statistically analyzed. The pathogenesis elements in the treatment of orifices were classified and counted, and the contents of syndrome differentiation and treatment in various Chinese herbal classics were extracted. ResultIn 76 Chinese herbal classics in the past dynasties, 93 Chinese herbal drugs for the treatment of orifices were selected. The nature of drugs was mainly warm, followed by cold and mild. The flavor was mainly pungent, followed by bitter and sweet. In terms of meridian tropism, drugs mainly acted on the lung meridian, followed by stomach, heart, liver, spleen, and kidney meridians. The pathogenesis elements of orifices could be divided into six categories, i.e., wind invasion, turbid obstruction and Qi stagnation, water and dampness stagnation, blood stasis and collaterals blockage, heat and toxin damage, deficiency of vital Qi and cold coagulation. ConclusionOrifices are mainly treated with drugs effective in dispelling wind and pathogenic factors, resolving turbidity and removing stagnation, inducing diuresis and eliminating dampness, promoting blood circulation and dredging collaterals, clearing heat and purging fire, tonifying deficiency and dispelling cold, which are used in combination. Eliminating pathogenic factors and dredging, tonifying deficiency and purging excess are the main characteristics of treatment of orifices based on syndrome differentiation, which is in line with the physiological dysfunction state of orifices in losing the function, evil Qi blockage and healthy Qi deficiency.

ABSTRACT

Cardiometabolic disease (CMD) is a clinical syndrome in which there is a causal relationship between metabolic abnormalities and cardiovascular damage. The incidence and mortality rates of CMD remain high despite the use of potent pharmacologic interventions and clinical therapeutic approaches. There is an urgent need for effective evidence-based comprehensive management measures to improve patients' lifespan and quality of life. From the concept of "nourishing through food" proposed in the Huangdi's Internal Classic (Huang Di Nei Jing) to the widespread application of modern dietary patterns such as dietary restriction, plant-based diets, and Jiangnan cuisine, dietary regulation plays a significant role in preventing diseases, early treatment of existing diseases, and recovery. This article systematically reviewed the traditional Chinese medicine (TCM) theory related to dietary patterns, elucidated the cutting-edge evidence and mechanisms of modern dietary patterns like dietary restriction in preventing and treating CMD, and explored the strategy of integrating TCM theory with dietary patterns, aiming to establish a new food-nutrition-medicine approach that combines traditional Chinese and western medicine and provide novel insights and directions for the clinical management of CMD.

ABSTRACT

Background Few studies have investigated the association between air pollution and arterial stiffness in Chinese population, and the findings are inconsistent. The problem of multicollinearity exists when modeling multiple air pollutants simultaneously. Objective To investigate potential association between air quality index (AQI) and population brachial-ankle pulse wave velocity (baPWV) in Beijing. Methods This study retrieved medical examination data of 2971 participants from the Beijing Health Management Cohort, who were under 60 years old and not yet retired, from January 1, 2015 to December 31, 2019. The most recent medical examination data available were utilized for this analysis. AQI data from 35 air pollution monitoring sites in Beijing and meteorological data (including atmospheric pressure, air temperature, wind speed, and relative humidity) from 16 meteorological monitoring stations from January 1, 2014 to December 31, 2019 were collected. An average AQI exposure level for 365 d before the date of physical examination for each participant was computed using inverse distance weighting. Multiple linear regression analysis was employed to investigate the relationship between AQI and baPWV in Beijing, after adjusting for confounding variables including age, gender, body mass index, mean arterial pressure, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, fasting blood glucose, atmospheric pressure, temperature, wind speed, relative humidity, medication history of diabetes, medication history of hypertension, cardiovascular disease, education, smoking status, drinking status, and physical activity intensity. Subgroup analysis was performed by age, sex, presence of diabetes, and presence of hypertension. Results AQI demonstrated an overall decreasing trend during the study period and was lower in the northern regions and higher in the southern regions of Beijing. After adjusting the confounding variables, each 10 unit increase in AQI was associated with 6.18 (95%CI: 1.25, 11.10) cm·s−1 increase in baPWV in all participants, 8.05 (95%CI: 2.32, 13.79) cm·s−1 increase in the participants <50 years, 15.82 (95%CI: 8.33, 23.31) cm·s−1 increase in the female group, 10.10 (95%CI: 4.66, 15.55) cm·s−1 increase in the participants without diabetes, and 9.41 (95%CI: 4.21, 14.62) cm·s−1 increase in the participants without hypertension. However, there was no statistically significant association observed between AQI and baPWV in the age group ≥50 years, the male group, the diabetic group, and the hypertensive group (P>0.05). Conclusion An increase in long-term AQI levels is associated with an elevation in the degree of arterial stiffness. Individuals under 50 years old, females, without hypertension or diabetes are susceptible populations to arterial stiffness when being exposed to air pollution. Improving air quality may contribute to prevent arterial stiffness.

ABSTRACT

Objective To construct a cardiovascular chip model for evaluating the damage of vascular glycocalyx induced by four marine toxins: okadaic acid (OA), conotoxin (CTX), tetrodotoxin (TTX) and gymnodimine (GYM), and explore the protective effect of triptolide on toxin-induced injury. Methods Human umbilical vein endothelial cells(HUVEC) were inoculated into a three-channel microfluidic chip. CCK-8 method and immunofluorescence staining were used to analyze the damage of cell viability and glycocalyx tissue induced by low, middle and high concentrations of marine toxin, as well as the protective effect of triptolide on toxin-induced injury. Results The cells in the cardiovascular chip grew well and had structurally intact glycocalyx. Compared with the control group, the activity of HUVEC cells were inhibited in group of the medium and high concentration of OA and high concentration of GYM (P<0.05). The activity of cells had not been inhibited by CTX and TTX significantly , but all the four toxins caused serious damage to the glycocalyx tissue (P<0.01). After pre-protection with triptolide, the toxicity of the four toxins to HUVEC cells and the damage rate of glycocalyx decreased significantly. Conclusion The four marine biotoxins could damage the activity and glycocalyx of HUVEC cells in a dose-dependent manner, while triptolide has a protective effect on HUVEC cells injured by toxin.

ABSTRACT

Breast cancer is a kind of malignant tumor discovered lately, with a high incidence and a poor prognosis. The shortage of relevant biological biomarkers lead to the unsatisfactory treatment efficacy and the early diagnosis in breast cancer. Metabolomics is a new discipline that uses high-throughput analysis techniques to study the dynamic changes of endogenous metabolites under the influence of different pathological physiological stimulation or gene mutations, which has provided a novel way for biomarker screening and disease diagnosis and treatment. The overview of metabolomics and its applications in breast cancer early diagnosis, drug efficacy evaluation, and disease prognosis were summarized in this review.

ABSTRACT

@#Chondroitin sulfate is an important component of extracellular matrix (ECM) in animal and human body. In recent years, chondroitin sulfate has been proven to have potential efficacy in biomedical application and has been widely used in bone regeneration and osteogenesis, especially in craniofacial reconstruction and dental medicine. Research shows that chondroitin sulfate derivatives and chondroitin sulfate composite scaffolds have great potential in promoting osteogenesis and biomineralization. However, due to the variety of chondroitin sulfate and various application forms, study on its mechanism of osteogenic repair is still insufficient. In this paper, biological characteristics, bone regeneration and osteogenesis of chondroitin sulfate, its application in different biomaterial design and future prospect are discussed.

ABSTRACT

Objective To optimize the microwave-assisted extraction process of green tea polyphenols. Methods The extraction yield of tea polyphenols was figured up by building the standard curve of gallic acid and examining the concentration of tea polyphenols in green tea extract with the introduction of a correction factor. The effects of four single factor levels of microwave extraction time, microwave output power, liquid-to-material yield, and ethanol volume fraction on the extraction yield of tea polyphenols were primarily studied in this experiment. The response surface was applied to further optimize the extraction process of green tea polyphenols after exploring the appropriate range of four single factor levels. Results The optimal extraction process was as follows: extraction time 37 s, microwave output power 350 w, material - liquid yield 1∶45 (g/ml), ethanol volume fraction 55%, and the actual extraction yield of tea polyphenols was 25.65%, which was not much different from the theoretical value. Conclusion The microwave-assisted green tea polyphenol extraction process optimized by response surface methodology is time-saving and practicable, and the extraction yield is high.
