Mechanisms of Qi-blood circulation and Qi deficiency syndrome in view of blood and interstitial fluid circulation

Xiaoke Bitong capsule alleviates inflammatory impairment via inhibition of the TNF signaling pathway to against diabetic peripheral neuropathy

BACKGROUND

Xiaoke Bitong capsule (XBC) is a crude herbal compound believed to tonify qi, improve blood circulation, and alleviate blood stasis. It has been used as an herbal formula for the prevention and treatment of diabetic peripheral neuropathy (DPN) under the guidance of traditional Chinese medicine (TCM). However, the pharmacological mechanisms by which XBC ameliorates DPN remain poorly understood. The interaction between pro-inflammatory factors and the activation of tumor necrosis factor (TNF) plays a critical role in the underlying mechanisms of DPN. XBC may protect against DPN through the regulation of the TNF pathway.

PURPOSE

Many studies show the association between DPN and nerve dysfunction, however, treatment options are limited. To identify specific therapeutic targets and active components of XBC that contribute to its anti-DPN effects, our study aimed to investigate the potential mechanism of action of XBC during the progression of DPN using a system pharmacology approach.

METHODS

An approach involving UPLC-Q-TOF/MS and network pharmacology was used to analyze the compositions, potential targets, and active pathways of XBC. Further, models of streptozocin (STZ) induced mouse and glucose induced RSC96 cells were established to explore the therapeutic effects of XBC. High glucose induced RSC96 cells were pretreated with small interfering RNA (siRNA) to identify potential therapeutic targets of DPN.

RESULTS

Seventy-one active compositions of XBC and five potential targets, including mitogen-activated protein kinase 8 (MAPK), interleukin-6 (IL-6), poly-ADP-ribose polymerase-1 (PARP1), vascular endothelial growth factor A (VEGFA), and transcription factor p65 (NF-κB), were considered as the potential regulators of DPN. In addition, the results revealed that the TNF signaling pathway was closely related to DPN. Moreover, DPN contributed to the decreased expressions of PI3K and AKT, increased TNF-α and IL-1β in RSC96 cells, which were both reversed by XBC or TNF-α siRNA.

CONCLUSION

XBC could protect against DPN by inhibiting the release of pro-inflammatory cytokines and regulating the activation of the TNF signaling pathway, further accelerating neurogenesis, and alleviating peripheral nerve lesions. Therefore, this study highlights the therapeutic value of XBC for DPN.

Citrus fruits, renowned for their abundant of phytochemicals and bioactive compounds, hold a prominent position as commercially grown fruits with health-promoting properties. In this context, tangerine peel (Citri Reticulatae Pericarpium, CRP) is garnering attention as a byproduct of citrus fruits. Within the framework of the circular economy, CRP has emerged as a focal point due to its potential health benefits. CRP, extracted from Citrus reticulata cv. and aged for over three years, has attracted increasing attention for its diverse health-promoting effects, including its anticancer, cardiovascular-protecting, gastrointestinal-modulating, antioxidant, anti-inflammatory, and neuroprotective properties. Moreover, CRP positively impacts skeletal health and various physiological functions. This review delves into the therapeutic effects and molecular mechanisms of CRP. The substantial therapeutic potential of CRP highlights the need for further research into its applications in both food and medicine. As a value-added functional ingredient, CRP and its constituents are extensively utilized in the development of food and health supplements, such as teas, porridges, and traditional medicinal formulations.

Western Medical Acupuncture Perception and Use for Pain Management Among Athletes: A Systematic Review

Purpose

This systematic review aims to assess the use and perception of "Western" medical acupuncture-based on conventional biomedical mechanisms and evidence-based medicine for diagnosis and needle placement-for pain management among athletes and their healthcare providers.

Methods

A systematic review is reported based on the PRISMA guidelines. PubMed, Web of Science, SPORTDiscus, Allied and Complementary Medicine databases, and Google Scholar were searched (search: from database inception to July 2023). Two authors independently conducted multi-stage screening, data extraction, and quality assessment. The outcomes of interest were prevalence of acupuncture prescriptions by healthcare professionals, prevalence of acupuncture use by athletes, and perceptions related to acupuncture effectiveness among healthcare professionals and athletes. Only studies wherein "Western" medical acupuncture was used for pain management were included.

Results

Our review included 11 observational studies and clinical trials. The prevalence of "Western" medical acupuncture prescription varied from 15.4% (UK) to 58.4% (US) among sports medicine healthcare professionals. Prevalence of acupuncture use among athletes ranged from 2.2% among college athletes in Palestine to 61% among professional football players in the Netherlands. Acupuncture was used for managing delayed-onset of soreness and pain due to various types of musculoskeletal injuries. Both athletes and their healthcare providers reported positive perceptions of acupuncture.

Conclusion

Our systematic review identifies a notable research gap in evaluating the practice and perception of "Western" medical acupuncture among healthcare professionals and athletes. Our findings suggest that "Western" medical acupuncture is not only prescribed by sport medicine professionals and used by athletes for diverse musculoskeletal pains but is also generally perceived positively for its effectiveness. Given the positive clinical experience of health professionals, athletes' favorable perception, and acupuncture's well-established safety profile, acupuncture should be given serious consideration-as a complementary approach-in the overall management of pain.

Efficacy of Moxibustion for Cancer-Related Fatigue in Patients with Breast Cancer: A Systematic Review and Meta-Analysis

INTRODUCTION

Breast cancer is the most commonly diagnosed cancer worldwide, and most patients experience fatigue. However, there are no effective treatments for cancer-related fatigue (CRF). Several randomized controlled trials (RCTs) have suggested that moxibustion improves CRF. We conducted a systematic review and meta-analysis to compare the differences in fatigue scale scores, quality of life, and clinical efficacy in patients with breast cancer who developed CRF and did versus did not receive moxibustion.

METHODS

RCTs were searched in 7 databases using a standardized search method from database inception to March 2023, and RCTs that met the inclusion criteria were selected.

RESULTS

Among 1337 initially identified RCTs, 10 RCTs involving 744 participants were selected for this study. The meta-analysis involved assessment of the revised Piper Fatigue Scale scores, Cancer Fatigue Scale scores, Karnofsky Performance Scale scores, Athens Insomnia Scale scores, clinical efficacy, and Qi deficiency syndrome scale scores. Compared with the control, moxibustion was associated with significantly better Piper Fatigue Scale scores (P < 0.0001), quality of life [Karnofsky Performance Scale scores (P < 0.0001)], clinical efficacy (P = 0.0007), and Qi deficiency syndrome scale scores (P = 0.02).

CONCLUSIONS

Moxibustion improves CRF in patients with breast cancer. The efficacy of moxibustion should be further examined by high-quality studies in various countries with patients subdivided by their breast cancer treatment status.

Review on the systems biology research of Yin-deficiency-heat syndrome in traditional Chinese medicine

Traditional Chinese medicine (TCM) is a systematic medical method that has existed for more than 3,000 years. Unlike Western medicine, the disease diagnosis in TCM is carried out by inspection, auscultation, olfaction, interrogation, and palpation. The patient is then treated according to the disease and corresponding TCM syndrome. However, the development of Chinese medicine is stagnated, partially because it can be influenced by subjective factors, such as the experience and knowledge of TCM practitioners, and there is a lack of relevant biological research on TCM syndromes. Yin-deficiency-heat (YDH) syndrome in TCM is characterized by a series of pathological changes caused by the insufficiency of Yin-fluid, inability to moisturize, and the failure to suppress Yang. In recent years, systems biology research on TCM syndromes has gradually become the focus of TCM research, including syndrome differentiation and functional research using systems biology methodologies such as proteomics, transcriptomics, and metabolomics. This journal aims to publish a series of issues on the systems biology research of TCM syndromes that can provide biological indicators for the syndrome differentiation of YDH syndrome and can provide perspectives on the biological research of YDH syndrome.

Chinese Medicine Phenomics (Chinmedphenomics): Personalized, Precise and Promising

The systematicness of phenomics and Traditional Chinese Medicine (TCM) enable these two disciplines to interlink with each other. This article discussed the similarity in theory and application between TCM and phenomics and illustrates their respective advantages in diagnosis and treatment of diseases, forming a new discipline eventually. Chinese medicine phenomics (Chinmedphenomics) is built on classic TCM, combined with phenomics technology, and the development of which needs the mega cohort with TCM syndrome and the characteristics of precision medicine as well as multi-disciplinary cooperation, which is personalized, precise and promising, providing unique scientific insights into understanding human health.

Correlation between Traditional Chinese Medicine Syndromes and Type 2 Myocardial Infarction in Critically Ill Patients with Pulmonary Disease

Background

Treatment based on syndrome differentiation under the traditional Chinese medicine (TCM) framework has been shown to be helpful in patients with coronary artery disease. We hypothesized that syndrome types could predict the risk of type 2 myocardial infarction (T2MI) caused by imbalance between myocardial oxygen supply and demand in critically ill patients with pulmonary disease.

Methods

This retrospective study included consecutive critically ill patients with pulmonary disease admitted to the ICU at Jiading District Central Hospital Affiliated Shanghai University of Medicine & Health Sciences from January 1, 2017, to July 1, 2019. Diagnosis of T2MI was based on the fourth universal definition of myocardial infarction. Risk factors associated with T2MI were identified using multivariate regression analysis.

Results

A total of 244 patients were included in the study: 78 who developed T2MI and the remaining 166 who did not develop T2MI during hospitalization. The incidence of phlegm syndrome and deficiency syndrome was 61.9% and 38.1%, respectively. In comparison with the patients with phlegm syndrome, the incidence of T2MI in patients with deficiency syndrome is significantly higher (40.9% vs. 26.5%, P=0.019). In multivariate logistic regression, T2MI was independently associated with the baseline troponin level (OR 12.682, 95% CI 1.397∼115.121; P=0.024), hemoglobin < 55 g/L (OR 12.76, 95% CI 2.359∼69.021; P=0.003), mechanical ventilation (OR 2.244, 95% CI 1.029∼4.892; P=0.042), and TCM deficiency syndrome (OR 2.214, 95% CI 1.032∼4.749; P=0.041). After adjusting for confounding factors in Cox regression models, the hazard ratio (95% confidence interval) of qi deficiency syndrome groups was 1.183 (95% CI 1.053∼3.123, P=0.032).

Conclusions

Patients with deficiency syndrome are at high risk of T2MI, especially those combined with qi deficiency syndrome.

Effect of Natural Chinese Herbal Supplements (TCMF4) on Lactation Performance and Serum Biomarkers in Peripartal Dairy Cows

This study examined the effect of mixed medicinal herbs from China in the ground form on milk yield and various blood metabolites before and after parturition in Holstein cows. Crushed Agastache rugosus, Scutellaria barbata, Pericarpium citri reticulate, and Radix glycyrrhizae were used to develop TCMF4. Thirty-two Chinese Holstein cows were randomly divided into a control group or groups receiving 0.1, 0.3, or 0.5 kg TCMF4/cow/d from −7 through 21 d relative to parturition. Blood samples for serum isolation were collected at −7, −1, 1, 7, 14, and 21 d relative to parturition and used to measure glucose, β-hydroxybutyric acid (BHBA), total protein, albumin, globulin, and alkaline phosphatase. Milk production was recorded daily for the first 21 d postpartum, and composition was analyzed at 7, 14, and 21 d. Data were analyzed using a one-way analysis of variance (ANOVA) for multiple comparisons. The average milk production during the first 21-d postpartum was 28.7 ± 6.9, 27.2 ± 7.1, 31.2 ± 6.8, and 38.5 ± 6.1 kg/d for control group and groups receiving 0.1, 0.3, or 0.5 kg TCMF4. Thus, average daily milk production increased between 9 to 34% by supplementation with TCMF4 compared with the control group. Compared with the control group, in the middle dose group, milk concentrations of lactose and total protein decreased by 21 and 19%, respectively, at d 7 around parturition, while total solids increased by 23% at d 21 in the high-dose group. Furthermore, compared with the control group, serum BHBA decreased by 50 and 20% at d −1 and 21 around parturition in the high-dose group. Overall, TCMF4 supplementation improved dry matter intake (DMI) and milk production of dairy cows during the periparturient period without adverse effects on liver function, and plasma BHBA concentrations of dairy cows tended to decrease when dietary TCMF4 increased, which suggested that TCMF4 might be used as potential additives in dairy cows to improve production performance.

Travel for mindfulness through Zen retreat experience: A case study at Donghua Zen Temple

This study seeks to contribute knowledge of the Zen retreat experience unique to Buddhist tourism. The research setting is the Zen retreats found at the Donghua Zen Temple in China. This study examined feedback obtained from 520 tourists who stayed at Zen retreats. Zen retreat organizer insights were obtained through online discussions. This study identified four motivations for, and three outcomes of, staying at Zen retreats. Within the Zen retreat experience, this study clarified four themes in knowledge growth (mingxin), three themes in spiritual growth (jianxing), and two mechanisms to foster knowledge and spiritual growth. This study further proposed a figure demonstrating Zen practitioners' lifelong journey, and a figure categorizing tourists in Buddhist tourism into Zen tourism, Zen lifestyle, and Zen retreat by level of involvement.

Exploring the Biochemical Basis of the Meridian Tropism Theory for the Qi-Invigorating Traditional Chinese Medicine Herb Panax ginseng

We examined the effect of the Qi-invigorating Traditional Chinese Medicines (TCM) herb Panax ginseng (P.G.) on mitochondrial functions and cellular antioxidant capacity in different organs of mice. We found that the P.G. extracts had a significant effect on tissues of mice, with the generation of total adenylate pool (TAP) enhanced in all visceral tissues, but not for the brain. The mitochondrial membrane potential (MMP) and antioxidant capacity reflected by superoxide dismutase (SOD) and glutathione (GSH) increased only for the meridian tissues that P.G. belongs to including Heart, Spleen and Lung. Reactive oxygen species (ROS), as a combined result of the increased energy metabolism and antioxidant capacity, varied in different organs. We concluded that: 1) the Qi-invigorating TCM herb P.G. had a significant effect on mice by enhancing TAP production in all of the visceral tissues examined, except for the brain; 2) for the meridional tissues of P.G. (Heart, Spleen and Lung), the P.G. extracts not only promoted the TAP production, but also boosted the antioxidant capacity demonstrated by the simultaneous increase in TAP, and SOD and GSH.

The Role of Acupuncture on the Gut-Brain-Microbiota Axis in Irritable Bowel Syndrome

Irritable bowel syndrome (IBS) is a chronic dysfunction of the gastrointestinal tract, commonly characterized by abdominal pain or abdominal discomfort. These symptoms can substantially reduce the quality of life and work productivity of the patients. The exact pathogenesis of IBS remains unclear, as it has become apparent that multiple pathways are activated in the condition, including inflammation, immunology, neurology and psychology. Recent evidence has shown that symptoms in IBS are related to the dysfunction of the nervous system, particularly the viscerosomatic pathway, through immune-to-brain communication. The potential link between brain-gut relationships is gut microbiota. The management of IBS mostly focuses on symptomatically treating the patients. There are a wide range of standard treatments, including pharmacological to psychological interventions which are effective in some patients. Therefore, a combination of therapies including both standard and complimentary treatments, including Traditional Chinese Medicine (TCM) such as acupuncture, have been used in treating IBS patients. Several in vivo and clinical studies have demonstrated the efficacy of acupuncture in treating IBS. Increasing attention has been paid to research regarding the action mechanisms of acupuncture for IBS. This paper summarizes and discusses the possible mechanisms associated with acupuncture on the pathophysiology of IBS, including gastrointestinal (GI) motility, visceral hypersensitivity, the immune system, neurotransmitters, and the brain-gut axis. The results fromin vivo and clinical studies have been included. In addition, the effects of acupuncture on gut microbiota in IBS are included and any contradictory findings are deliberated.

Impact of the COVID-19 pandemic on intention to use traditional Chinese medicine: A cross-sectional study based on the theory of planned behavior

Objective

Coronavirus disease 2019 (COVID-19) has become an increasingly severe public health emergency. Although traditional Chinese medicine (TCM) has helped to combat COVID-19, public perception of TCM remains controversial. We used the theory of planned behavior (TPB) to identify factors that affect the intention to use TCM.

Methods

A cross-sectional web-based survey of 10,824 individuals from the general public was conducted between March 16 and April 2, 2020. The participants were recruited using a snowball sampling method. Data were collected using a self-administered questionnaire, based on the TPB. The questionnaire consisted of demographic characteristics and TPB structures. Structural equation modeling was used to identify predictors of intention.

Results

The results indicated the model explained 77.5% and 71.9% of intention and attitude variance. Intention to use TCM had the strongest relationship with attitude (P < 0.001), followed by past behavior (P < 0.001), subjective norms (P < 0.001) and perceived behavioral control (P < 0.001). Attitudes toward TCM were significantly affected by perceived behavioral control (P < 0.001), subjective norms (P < 0.001) and cognition of TCM (P < 0.001).

Conclusion

Attitude is a key factor in determining the intention to use TCM, followed by past behaviors, subjective norms and perceived behavioral control. Our results offer important implications for health policy makers to promote the use of TCM.

Is 6-Shogaol an Effective Phytochemical for Patients With Lower-risk Myelodysplastic Syndrome? A Narrative Review

Myelodysplastic syndrome (MDS) evolves due to genomic instability, dysregulated signaling pathways, and overproduction of inflammatory markers. Reactive oxygen species contribute to the inflammatory response, which causes gene damage, cellular remodeling, and fibrosis. MDS can be a debilitating condition, and management options in patients with MDS aim to improve cytopenias, delay disease progression, and enhance quality of life. High serum ferritin levels, a source of iron for reactive oxygen species production, correlate with a higher risk of progression to acute myeloid leukemia, and iron overload is compounded by blood transfusions given to improve anemia. 6-shogaol is a natural phenolic compound formed when ginger is exposed to heat and/or acidic conditions, and it has been shown to possess anti-tumor activity against leukemia cell lines and antioxidant effects. This narrative review assessed the potential benefits of this phytochemical in lower-risk MDS patients through examining the current evidence on the pharmacological and therapeutic properties of ginger and 6-shogaol.

Association between cancer-related fatigue and traditional Chinese medicine body constitution in female patients with breast cancer

BACKGROUND

Cancer-related fatigue (CRF) is a common psychosomatic problem in breast cancer patients. Traditional Chinese medicine (TCM) has been used to address symptoms in patients with CRF. Identification of the specific constitution in TCM is essential for personalized care.

AIM

To explore the relationship between fatigue and specific constitutions in breast cancer.

EXPERIMENTAL PROCEDURE

We conducted a cross-sectional study in all breast cancer patients at Kaohsiung Chang Gung Memorial Hospital in Taiwan. The severity of fatigue was determined using the Brief Fatigue Inventory-Taiwanese (BFI-T) form. TCM patterns were determined using the Body Constitution Questionnaire (BCQ). The relationship between constitution and fatigue was analyzed using logistic regression.

RESULTS

We recruited 110 breast cancer patients with fatigue (mean age: 55 ± 11 years). The mean duration of breast cancer was 17.4 months. The major constitution among these patients with fatigue was Yang-Qi deficiency (50%). Phlegm-Stasis syndrome was correlated with a duration of breast cancer of more than 18 months (p = 0.02). Out of all participants, 42.7% (n = 47) reported clinically significant fatigue (BFI-T score ≥4). According to logistic regression, the score of Yang-Qi deficiency [odds ratio (OR): 3.5, 95% confidence interval (CI): 1.49-8.21, p < 0.01] was also associated with clinically significant fatigue.

CONCLUSION

Yang-Qi deficiency is associated with clinically significant fatigue in breast cancer patients. However, the association of Phlegm-Stasis syndrome and fatigue as disease duration increases cannot be ignored. Further studies are needed to determine whether treating both constitutions integrating TCM treatment can alleviate patients' fatigue symptoms.

Potential Benefits of Acupuncture and Herbs for Obesity-Related Chronic Inflammation by Adipokines

The adipose tissue is an organ that stores energy in the form of fats. It also has been known as an endocrine playing an integral role in metabolic homeostasis by secreting various adipokines. In obesity, the adipokine components and secretion patterns are altered toward proinflammation with weight gain, causing low chronic inflammation, which is closely linked to various metabolic diseases. Acupuncture and herbs are used for the management of obesity and its comorbidities, and it has been observed that these therapies affect the amount of expression and concentration of adipokines with improved metabolic phenotypes in both animal and human metabolic diseases. In this review, we discuss the role of adipokines and summarize beneficial effects of the treatments such as electroacupuncture, pharmacopuncture, catgut embedding acupuncture, and single and multiple medicinal herbs on obesity and its relations to adipokine composition. It will provide a new insight for applying adipokines as surrogate markers in complementary and alternative medicine practice.

Efficacy of Electroacupuncture Combined with Auricular Point Pressing in Improving Mental Well-Being among Individuals with Heroin Use Disorder: A Randomized Controlled Crossover Trial and Pilot Study

Objective

To evaluate the clinical efficacy of combining electroacupuncture with auricular point pressing in improving quality of life of individuals with heroin use disorder undergoing methadone maintenance treatment.

Design

A randomized controlled crossover trial.

Subjects

50 participants were recruited from Taipei City Hospital, Linsen Chinese Medicine and Kunming branches, and randomly allocated to treatment groups.

Method

The 36-Item Short Form Health Survey (SF-36) was used. Group A received electroacupuncture at the Hegu (LI4) and Zusanli (ST36) and auricular point pressing on Ear Shenmen, and Group B received only auricular point pressing on Ear Shenmen biweekly for 4 weeks. After a 1-week washout period, crossover of the groups was performed.

Results

The SF-36 mental component scores of the combined treatment group improved relative to the single treatment group (11.09 vs. 10.33, p=0.023). Methadone dosage was reduced in both groups (combined therapy group: 8.58 ± 4.17/7.76 ± 4.11 (baseline/posttreatment) vs. single therapy group: 8.36 ± 4.20/8.30 ± .28, p=0.001).

Conclusion

Combined therapy of high-frequency electroacupuncture with auricular point pressing had better efficacy in enhancing quality of life, especially for mental well-being, and in gradually reducing methadone dosage.

A metabonomics and lipidomics based network pharmacology study of qi-tonifying effects of honey-processed Astragalus on spleen qi deficiency rats

Honey-processed Astragalus is a dosage form of radix Astragali processed with honey, which is deemed to contain better qi-tonifying effects in traditional Chinese medicine theroy. Our previous study has demonstrated that honey-processed Astragalus exhibited a better effect on reinforcing qi (vital energy) and immune improvement toward spleen qi deficiency compared with radix Astragali. However, the detailed mechanisms related to qi-tonifying effects of honey-processed Astragalus is still unclear. In this study, we evaluated the qi-tonifying effects of honey-processed Astragalus on spleen qi deficiency rats and predicted the mechanisms by aggregating metabonomics, lipidomics and network pharmacology. The results revealed that body weights, symptom scores, the levels of red blood cell, white blood cell, lymphocyte, spleen and thymus indexes, and three cytokines (TNF-α, IL-6, IFN-γ) in honey-processed Astragalus treated rats were improved in comparison with spleen qi deficiency rats. In parallel, based on the 26 biomarkers screened in metabonomics and lipidomics, we inferred that glycerophospholipid metabolism significantly regulated in pathway analysis was connected with qi-tonifying effects. Moreover, the network pharmacology analysis concluded that the compounds targets of honey-processed Astragalus CDK2, NOS3, MAPK14, PTGS1 and PTGS2 interacted with markers targets PLA2G(s) family and LYPLA1 could be responsible for regulation of glycerophospholipid metabolism to develop qi-tonifying effects. What's more, the above processes were possibly through VEGF signaling and MAPK signaling pathways.

Association of TCM body constitution with insulin resistance and risk of diabetes in impaired glucose regulation patients

Background

Impaired glucose regulation (IGR) patients have increased risk of type 2 diabetes mellitus (T2DM). Identifying relevant risk factors in IGR subjects could facilitate early detection and prevention of IGR progression to diabetes. This study investigated the association between Traditional Chinese Medicine (TCM) body constitution and serum cytokines, and whether body constitution could independently predict diabetes in IGR subjects.

Method

Patients with IGR (n = 306) received a blood test and their body constitution type was assessed using a body constitution questionnaire (BCQ). Serum levels of cytokines were measured by ELISA. Patients were followed up for at least three years, and their status of diabetes were recorded. Multivariate logistic regression was used to estimate odds ratios (ORs) of diabetes for body constitution.

Results

Phlegm-damp, Damp-heat and Qi-deficiency were three most common unbanlenced constitutions among IGR subjects. Phlegm-damp and Damp-heat constitution subjects showed higher serum levels of interleukin 6 (IL-6), tumour necrosis factor-α (TNF-α), leptin and lower serum levels of adiponectin (P<0.05). Qi-deficiency constitution subjects showed higher serum levels of leptin and lower serum levels of adiponectin, glucagon-like peptide-1 (GLP-1) and gastric inhibitory polypeptide (GIP) (P<0.05). Subjects with Phlegm-damp or Damp-heat constitution demonstrated a significantly higher risk of diabetes (P<0.05).

Conclusion

Phlegm-damp and Damp-heat TCM body constitution are strongly associated with abnormal serum cytokines, and could potentially serve as a predictor of diabetes in IGR subjects. Body constitution can help to identify IGR subjects who are at a high risk of progression to diabetes.

Altered Impedance of Ear Acupuncture Point MT2 in Breast Cancer Patients: A Preliminary Observation

Skin impedance at acupuncture points (APs) has been used as a diagnostic aid for more than 50 years. In this study, we have a diagnostic tool (JXT-2008) to measure the skin impedance of ear APs of 30 breast cancer patients and the corresponding skin impedance of ear APs of 30 healthy humans, and then we compared these changes in ear AP impedance in breast cancer patients and healthy individuals.

Effects of TCMC on Transformation of Good Health Status to Suboptimal Health Status: A Nested Case-Control Study

To explore the effects of traditional Chinese medicine constitution (TCMC) on transformation of good health status to suboptimal health status (SHS), we conducted a nested case-control study among college students in China. During the 18-month mean follow-up time, 543 cases of SHS (42.7%) occurred in 1273 healthy students. There was a significant (P = 0.000) and marked reduction in SHMS V1.0 total score in the case group at the 18-month follow-up (69.32 ± 5.45) compared with baseline (78.60 ± 4.70), but there was no significant change in the control group. Conditional logistic regression analysis showed that respondents reporting Yin-deficiency and Qi-deficiency were, respectively, 2.247 and 2.198 times more likely to develop SHS, while tendency to Yin-deficiency and tendency to Damp-heat were, respectively, 1.642 and 1.506 times more likely to develop SHS. However, the Balanced Constitution was a significant protective factor (OR 0.649; P < 0.05). Altogether, these findings demonstrate that Yin-deficiency, Qi-deficiency, tendency to Yin-deficiency, and tendency to Damp-heat appeared to induce a change in health status to SHS, while the Balanced Constitution seemed to restrain this change. We conclude that regulating the unbalanced TCMC (such as Yin-deficiency and Qi-deficiency) may prevent a healthy status developing into SHS or lead to the regression of SHS.

Circulating MicroRNA Profiles Differ between Qi-Stagnation and Qi-Deficiency in Coronary Heart Disease Patients with Blood Stasis Syndrome

We compared the circulating microRNA profiles of Qi-stagnation (QSB) and Qi-deficiency (QDB) in coronary heart disease (CHD) patients with blood stasis syndrome. Twenty-nine CHD patients were divided into QSB group and QDB group. The analysis was carried out through comparing their circulating microRNA profiles and the following bioinformatics analysis. The number of differential miRNAs in QDB group was much more than that in QSB group. Functional annotations of the differentially expressed miRNAs target genes in the QSB group and QDB group were, respectively, related to regulation of cellular component organization, regulation of glucose metabolic process, and so forth and protein kinase cascade, phosphate metabolic process, and so forth. KEGG pathway analysis showed that the process Qi-deficiency was associated with phagocytosis including endocytosis and mTOR signaling pathway. Specifically, pathway of cell adhesion molecules played the crucial role in the pathological process of Qi-stagnation, with a unique upregulation except for pathways associated with cancer signal. MicroRNA-gene-net analysis indicated that let-7c, miR-4487, miR-619, miR-8075, miR-6735, and miR-32-5p and miR-17-5p, miR-130a, and miR 320 family had the most important and extensive regulatory function for Qi-stagnation syndromes and Qi-deficiency syndromes, respectively. Differentially expressed miRNAs and concerned pathways suggest different molecular mechanisms that may mediate the pathological process of QSB and QDB syndromes.

Relationship between EGF, TGFA, and EGFR Gene Polymorphisms and Traditional Chinese Medicine ZHENG in Gastric Cancer

In traditional Chinese medicine (TCM), correct syndrome differentiation is the most important principle guiding the prescription of Chinese herbal formulae for the treatment of gastric cancer (GC). We aimed to reveal the genetic mechanisms underlying GC syndrome differentiation (ZHENG) in a population of 387 GC patients. Twenty-nine single nucleotide polymorphisms (SNPs) in EGF, TGFA, and EGFR were investigated. Two SNPs, rs11466285 in TGFA and rs884225 in EGFR, were significantly associated with the distribution of ZHENG (P < 0.05). The rs11466285 TT genotype increased the risk of damp heat with toxin (DHT) and deficiency of both Qi and yin (DQY) compared with obstruction of blood stasis (OBS). The rs884225 AA genotype could increase the risk of DQY and deficiency of both Qi and blood (DQB) compared with yin deficiency due to stomach heat (YDSH). Parallel comparison among the SNPs and syndrome types revealed that DQB was distinct from YDSH, disharmony between the liver and stomach, stagnation of phlegm muddiness (SPM), OBS, and other syndromes at several SNP loci (P < 0.05). The rs11466285 TT and rs884225 AA genotypes exhibit increased risk of DQB compared with OBS and SPM (P < 0.05), respectively. In conclusion, the formation of GC ZHENG was related to EGF, TGFA, and EGFR gene polymorphisms.

Immunomodulatory effects of Hedysarum polybotrys extract in mice macrophages, splenocytes and leucopenia

Astragali Radix (Huang-Qi) is a popular herbal medicine commonly used as a constituent in tonic herbal preparations. Hedysarum polybotrys Handel-Mazzetti is one species used of Astragali Radix. In this study, the immunomodulatory properties of H. polybotrys were explored by LPS-activated and SNP-treated RAW 264.7 cells and splenocytes and, daunoblastina-induced leucopenia BALB/c mice. Formononetin was used as the bioactive marker to monitor the quality of the H. polybotrys extracts. H. polybotrys was extracted with hot-water and methanol, and MeOH extract partitioned with H₂O (M-H) and ethyl acetate (M-EA) to yield four different fractions. M-EA had the highest formononetin and total proanthocyanidin content and showed stronger inhibitory effects on the production and expression of NO, PGE₂, iNOS and COX-2 in LPS-activated RAW 264.7 cells and splenocytes than the other fractions. In addition, M-EA significantly stimulated the proliferation of LPS-activated RAW 264.7 cells and splenocytes, enhanced NO radicals scavenging and attenuated NO-induced cytotoxicity. Furthermore, M-EA also significantly increased the rate of recovery of white blood cells level in daunoblastina-induced leucopenia mice. These evidences suggest that this traditional Qi-tonifying herb has potential effects in clinical conditions when immune-enhancing and anti-inflammatory effect is desired.
