Prospect of value and application of transcutaneous electrical acupoint stimulation to control blood pressure in proactive healthcare perspective. / 主动健康视域下经皮穴位电刺激调控血压的价值与应用展望.

Hypertension is a global problem threatening human health and life. Although there are many antihypertensive drugs, the low compliance of medication affects its efficacy, and the effect in regulating hypertension has become increasingly prominent. Focusing on the new trend of proactive healthcare management, in the present paper, we made a summary about the status and existing problems of transcutaneous electrical acupoint stimulation (TEAS) in the regulation of blood pressure, and put forward some suggestions, such as selecting acupoints based on classical acupuncture theory to highlight the advantages of TEAS to control blood pressure as a whole, optimizing and screening the parameters of TEAS in the regulation of blood pressure, expanding the research observation indexes etc. We also made a prospect about its future application, hoping to provide new ideas for the proactive regulation, whole-process regulation and integrated regulation of blood pressure.

Fractional extraction of lignin from coffee beans with low cytotoxicity, excellent anticancer and antioxidant activities.

Lignin, a biopolymer generated from renewable resources, is widely present in terrestrial plants and possesses notable biosafety characteristics. The objective of this work was to assess the edible safety, in vitro antioxidant, and anti-cancer properties of various lignin fractions isolated from commercially available coffee beans often used for coffee preparation. The findings suggest that the phenolic hydroxyl content increased from 3.26 mmol/g (ED70L) to 5.81 mmol/g (ED0L) with decreasing molecular weight, which resulted in more significant antioxidant properties of the low molecular weight lignin fraction. The findings of the study indicate that the viability of RAW 264.7 and HaCaT cells decreased as the quantity of lignin fractions increased. It was observed that concentrations below 200 µg/mL did not exhibit any harmful effects on normal cells. The results of the study demonstrated a significant reduction of cancer cell growth (specifically A375 cells) at a concentration of 800 µg/mL for all lignin fractions, with an observed inhibition rate of 95 %. The results of this study indicate that the lignin extracts derived from coffee beans exhibit significant potential in mitigating diseases resulting from excessive radical production. Furthermore, these extracts show promise as natural antioxidants and anti-cancer agents.

Efficacy and Safety of Chinese Medicine Resuscitation Pack for Enhanced Recovery after Bronchoscopy: A Randomized, Single-Blind, Placebo-Controlled Clinical Trial.

OBJECTIVE: To evaluate the efficacy and safety of a hospital-made resuscitation pack, a Chinese medicinal herbal compound formula designed to enhance recovery in post-bronchoscopy patients. METHODS: In this randomized, single-blind, placebo-controlled clinical trial, eligible patients were randomly assigned 1:1 to either the treatment or control groups. The patients in the treatment group applied the resuscitation pack, which contained aromatic compounded Chinese herbs. The patients in the control group applied a hospital-made, single herb placebo pack. Packs were placed on the Tiantu (CV 22) acupuncture point for 4 h as soon as the bronchoscopy finished. Efficacy indicators, such as recovery time, patients' symptoms including nausea and dizziness, and adverse events (AEs) were observed and compared. The outcome indices were evaluated at baseline, 1 and 24 h after the bronchoscopy. Subgroup analysis was further performed by patients' age and depth of sedation. RESULTS: When applying generalized estimating equations (GEE) to evaluate the intensity of post-bronchoscopy nausea and vomiting, the intensity was lower in the treatment group (163 cases) compared with the control group (162 cases; 95% CI: 0.004, 0.099, P=0.03]. Also, significantly lower intensity of nausea was observed in the 60-70 years of age subgroup (95% CI: 0.029, 0.169, P=0.006) and deep sedation subgroup (95% CI: 0.002, 0.124; P=0.04). There was no significant difference in dizziness between two groups by GEE (95% CI: -0.134, 0.297; P=0.459). In addition, no serious AEs were observed in either group. CONCLUSIONS: Our study found that the resuscitation pack markedly improved patients' symptoms by reducing nausea and vomiting after bronchoscopy without AEs, compared with placebo in the perioperative period.

Effects of traditional Chinese culture-based bibliotherapy on the spiritual health of patients with liver cancer.

BACKGROUND: Liver cancer is a serious global health problem and is associated with poor spiritual health. Bibliotherapy is beneficial in improving health outcomes in cancer patients, yet there is a lack of empirical evidence of its effect on the spiritual health of liver cancer patients in China. The study aimed to investigate the effects of bibliotherapy based on Chinese traditional culture on the spiritual health of patients with liver cancer in China. This study was approved by the Ethics Committee of Hunan Normal University School of Medicine and registered with the Chinese Clinical Trial Registry with the registration (No: 2021260), which registration in June 30th 2021. METHODS: A total of 60 patients with liver cancer were divided into the intervention group (n = 30) and the control group (n = 30) through WeChat. The intervention group received bibliotherapy therapy based on traditional Chinese culture, while the control group received routine care. Spiritual health was assessed using the Spiritual Attitude and Involvement List (SAIL) and compared before and after the intervention between the two groups. The chi-square test and t-test were used to analyze the intervention effects. RESULTS: The two groups were comparable in all baseline characteristics including the SAIL score. After 5 weeks of intervention, the score of SAIL increased significantly from 96.76 ± 15.08 to 106.93 ± 13.82 in the intervention group (t = - 29.380, p < 0.001), while no significant difference in SAIL score was observed in the control group (from 95.27 ± 16.40 to 95.31 ± 16.24, t = - 0.189, p = 0.852). Similar patterns were also observed in its three dimensions of connecting with oneself, connecting with the environment, and connecting with transcendence. CONCLUSIONS: Our study showed that bibliotherapy based on traditional Chinese culture using the WeChat platform can greatly improve the spiritual health of patients with liver cancer and has the potential to be widely applied to cancer patients to improve their well-being.

Development and evaluation of short-form version of the Constitution in Chinese Medicine Questionnaire: study a new and best brief instrument of Chinese medicine for health management.

BACKGROUND: More efficient instruments for body constitution identification are needed for clinical practice. We aimed to develop the short-form version of the Constitution in Chinese Medicine Questionnaire (CCMQ) and evaluate for health management. METHODS: First, the short forms were developed through expert survey, classical test theory (CTT), and modern item response (IRT) based on the CCMQ. A combination of e-mail and manual methods was used in expert survey. Then, five indexes of CTT including criteria value-critical ratio, correlation coefficient, discrete tendency, internal consistency, and factor loading were used. And, IRT method was used through analyzing the discrimination and difficulty parameters of items. Second, the three top-ranked items of each constitution scale were selected for the simplified CCMQ, based on the three combined methods of different conditions and weights. Third, The psychometric properties such as completion time, validity (Construct, criterion, and divergent validity), and reliability (test-retest and internal consistency reliability) were evaluated. Finally, the diagnostic validity of the best short-form used receiver operating characteristic (ROC) curve. RESULTS: Three short-form editions were developed, and retained items 27, 23 and 27, which are named as WangQi nine body constitution questionnaire of Traditional Chinese Medicine (short-form) (SF-WQ9CCMQ)- A, B, and C, respectively. SF-WQ9CCMQ- A is showed the best psychometric property on Construct validity, Criterion validity, test-retest reliability and internal consistency reliability. The diagnostic validity indicated that the area under the ROC curve was 0.928 (95%CI: 0.924-0.932) for the Gentleness constitution scale, and were 0.895-0.969 and 0.911-0.981 for unbalance constitution scales using the cut-off value of the original CCMQ as 40 ("yes" standard) and 30 ("tendency" standard), respectively. CONCLUSIONS: Our study successfully developed a well short-form which has good psychometric property, and excellent diagnostic validity consistent with the original.

Chinese Herbal Medicine for the Treatment of Adult Viral Myocarditis: An Overview of Systematic Reviews and Meta-analyses of Randomized Controlled Trials.

PURPOSE: Viral myocarditis (VMC) is a life-threatening disease that can affect all ages and genders, with middle-aged adults being particularly susceptible. Numerous systematic reviews have been conducted to investigate the efficacy and safety of Chinese herbal medicine (CHM) in treating adult viral myocarditis (AVM). The objective of this study was to conduct a comprehensive overview of systematic reviews and meta-analyses of randomized controlled trials (RCTs) regarding the efficacy and safety of CHM for AVM. METHODS: A comprehensive systematic search was conducted across 8 electronic databases from their inception to June 23, 2022, augmented by manual searches of the gray literature. Systematic reviews were independently selected and data extracted in accordance with predetermined criteria by 2 reviewers. Included systematic reviews were assessed for methodologic and reporting quality using Assessing the Methodological Quality of Systematic Reviews 2 and Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The quality of evidence relating to outcome measures was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation tool. Recalculation of effect sizes and subsequent determination of 95% CIs were conducted with either a fixed-effects or random-effects model. FINDINGS: The current overview of systematic reviews included a total of 6 systematic reviews, which reported on 67 RCTs with a participant pool of 5611 individuals. The findings of our study indicate that the combination of CHM and Western medications had positive effects on the effective rate, cure rate, ECG recovery, atrial premature contraction/premature ventricular contraction, left ventricular ejection fraction, myocardial enzymes, and improvement of clinical symptoms for AVM. The adverse drug reactions in the combination therapy group were generally less than or lighter than that in the Western medication group (relative risk = 0.79; 95% CI, 0.44-1.40; P > 0.05, I2 = 0). IMPLICATIONS: Our research results provide evidence that combining CHM with Western medicine could offer potential benefits for patients with AVM. However, the number of studies included in our review is limited and the methodologic quality of these studies is modest. Therefore, there are potential uncertainties regarding the conclusion that CHM with Western medication may benefit patients with AVM. We call for more large-scale, high-quality studies with standardized designs to further verify and support our findings. This would promote a better understanding of the efficacy and safety profile of CHM and provide reliable reference evidence for clinical practice and policy making. Moreover, future research should explore optimal drug combinations, examine therapeutic doses and durations of CHM combination therapy, and evaluate its long-term efficacy and safety.

[Effects of moxibustion at "Tianshu"（ST25） and "Shangjuxu" （ST37） on colonic metabolites and inflammatory factors in rats with Crohn's disease].

OBJECTIVE: To observe the effects of moxibustion at "Tianshu"（ST25） and "Shangjuxu"（ST37） on the colonic metabolites and inflammatory factors in rats with Crohn's disease（CD）, so as to explore the mechanisms of moxibustion in protecting colon of CD rats based on metabolomics. METHODS: Twelve rats were first randomly selected from 36 male SD rats as a normal group（NG）. The CD model was induced by 2, 4, 6 trinitrobenzene sulfonic acid（TNBS） enema on the rest 24 rats. After successful modeling, rats were randomly divided into model（TNBS） and moxibustion（TNBS+MOX） groups（n=10 rats/group）. Moxibustion was applied at bilateral ST25 and ST37 for 30 min, once daily for 7 consecutive days in the TNBS+MOX group, while rats in the NG and TNBS groups did not receive any interventions. Body weight of rats was recorded and disease activity index（DAI） was assessed during the experiment. After interventions, HE staining was performed to observe pathological damage of colon. Serum levels of inflammatory factors were measured by ELISA. NMR hydrogen spectroscopy was used to detect colonic metabolites of each group, and orthogonal partial least squares discriminant analysis（OPLS-DA） was used to screen differential colonic metabolites between groups, followed by pathway analysis using MetaboAnalyst 5.0 platform. RESULTS: After modeling, compared with the NG group, the body weight of the rats in the TNBS group was significantly decreased（P<0.05）, the DAI score was increased （P<0.05）, the colon had obvious inflammatory damage and the pathological injury index was increased（P<0.05）, and levels of serum tumor necrosis factor-α（TNF-α）, interleukin（IL）-1ß and interferon-γ（IFN-γ） were significantly increased（P<0.05）. After moxibustion intervention, compared with the TNBS group, the body weight was significantly increased（P<0.05）, while the levels of serum TNF-α, IL-1ß, IFN-γ, and DAI score of the rats in the TNBS+MOX group were significantly decreased（P<0.05）, with alleviated colonic inflammatory injury detected by HE staining. Compared with the NG group, the relative expressions of colonic hypoxanthine, betaine, creatine, inositol, taurine, uracil, and methanol of the TNBS group were decreased（P<0.05）, while the relative expressions of histidine, leucine, proline, lysine, isoleucine, phenylalanine, tyrosine, propionic acid, and valine were increased（P<0.05） in the TNBS group, among which, relative expressions of hypoxanthine, leucine, lysine, isoleucine, betaine, tyrosine, and taurine were reversed in the TNBS+MOX group relevant to the TNBS group, mainly involving phenylalanine, tyrosine and tryptophan biosynthesis, and taurine and subtaurine metabolism pathway. CONCLUSION: The mechanism of moxibustion at ST25 and ST37 for CD may be related to improving colon metabolic disorder state by regulating multiple metabolic metabolites and metabolic pathways, and reducing the level of inflammatory factors, so as to maintain intestinal immune homeostasis.

OBJECTIVE: This study aimed to examine the effects of mindfulness-based stress reduction (MBSR) in patients with acute myocardial infarction (AMI) after primary percutaneous coronary intervention (PPCI). METHODS: A retrospective study was conducted with data collected from AMI patients who underwent successful PPCI. The study included 61 cases that received 8-week MBSR intervention (MBSR group) and 61 cases that received weekly health education (control group) over the same period. Outcome measures, including hemodynamic parameters, psychosocial characteristics [Hospital Anxiety and Depression Scale (HADS), Perceived Stress Scale (PSS), Perceived Social Support Scale (PSSS)], health-related quality of life [HRQoL, 7-item Seattle Angina Questionnaire (SAQ-7)], and major adverse cardiovascular events (MACE), were assessed at baseline (T1), post-intervention (T2), 1 month after the post-intervention (T3) and 3 months after the post-intervention (T4). RESULTS: Compared to the control group, the MBSR group showed improvements in blood pressure, specifically in systolic blood pressure (SBP) at T4, and diastolic blood pressure (DBP) at T3 and T4, and mean arterial blood pressure (MABP) at T3 and T4. Additionally, the MBSR group had lower scores of anxiety and perceived stress (HADS, PSS) and higher scores of perceived social support (PSSS) after the intervention. Furthermore, the MBSR group had higher scores on the SAQ-7 at all measurement points. The control group had a significantly higher total MACE rate compared to the MBSR group (26.23% vs. 9.84%). CONCLUSIONS: This study provides support for the potential benefits of MBSR as an adjunctive treatment for AMI patients undergoing PPCI.

Lutein inhibits tumor progression through the ATR/Chk1/p53 signaling pathway in non-small cell lung cancer.

Lung cancer is the leading cause of cancer-related death. In particular, non-small cell lung cancer (NSCLC) accounts for approximately 85% of all lung cancer cases. Due to tumor resistance and the toxicity of chemotherapeutic agents, it is increasingly critical to discover novel, potent antitumorigenic drugs for treating NSCLC. Lutein, a carotenoid, has been reported to exert toxic effects on cells in several tumor types. However, the detailed functions and underlying mechanisms of lutein in NSCLC remain elusive. The present study showed that lutein significantly and dose-dependently inhibited cell proliferation, arrested the cell cycle at the G0/G1 phase, and induced apoptosis in NSCLC cells. RNA-sequencing analysis revealed that the p53 signaling pathway was the most significantly upregulated in lutein-treated A549 cells. Mechanistically, lutein exerted antitumorigenic effects by inducing DNA damage and subsequently activating the ATR/Chk1/p53 signaling pathway in A549 cells. In vivo, lutein impeded tumor growth in mice and prolonged their survival. In conclusion, our findings demonstrate the antitumorigenic potential of lutein and reveal its molecular mechanism of action, suggesting that lutein is a promising candidate for clinical NSCLC treatment.

The interaction study of soluble pectin fiber and surimi protein network from silver carp (Hypophthalmichthys molitrix) based on a new prediction model.

Pure surimi of silver carp (Hypophthalmichthys molitrix) cannot meet the texture requirements in novel 3D printing of food. In this work, the effect mechanism of adding soluble pectin fiber on the quality of surimi was studied at molecular scale, and the interaction has been discussed by a novel prediction model. In comparison with pure surimi, pH and water-holding capacity decreased with increasing pectin, and texture properties improved. The storage modulus firstly rose and then decreased, reaching a maximum value of 15012 Pa at 0.5 % pectin addition. The thermal transition temperature of myosin was moved from 52.13 to 49.80 °C. Pectin extended the T22 relaxation time, suggesting a decrease in immobilized water. A new Time-series prediction model and interaction analysis further explored the intrinsic correlation of various parameters of surimi with different pectin additions. This work contributes to add our understanding of pectin application in surimi products in future special dietary food.

[Effect of herbal cake-separated moxibustion on behavioral stress reactions and blood lactic acid level and muscular AMPK/PGC-1α signaling in rats with chronic fatigue syndrome].

OBJECTIVE: To observe the effect of herbal cake-separated moxibustion (HCSM) on serum lactic acid (BLA) level and AMPK/PGC-1α signaling pathway in the quadriceps femoris in chronic fatigue syndrome (CFS) rats, so as to explore its mechanisms underlying improvement of CFS. METHODS: According to the random number table, 50 SD rats were divided into blank control, model, HCSM, sham HCSM and medication (herbal medicine gavage) groups, with 10 rats in each group. The CFS model was established by using chronic restraint and exhaustive swimming, alternately, once daily for 21 days. The herbal cake was made of Xiaoyao Powder (Mental Ease Powder, composed of [Danggui (Radix Angelicae Sinensis), Baishao (Radix Paeoniae Alba), Chaihu (Radix Bupleuri), Fuling (Poria), Baizhu (Rhizoma Atractylodis, Macrocephalae), etc.]. The HCSM was applied to "Shenque" (CV8), "Guanyuan "(CV4), bilateral "Zusanli" (ST36) and "Qimen" (LR14), 5 moxa-cones for each acupoint, once daily for 10 days. For sham HCSM, the excipient was instead of herbal cake, and the same 5 moxa-cones was given as the HCSM group. Rats of the medication group received gavage of Xiaoyao Powder suspension (60 mg·kg-1), once daily for 10 days. The open field test and tail suspension test were conducted for determining the animals' locomotor activity. The blood sample was taken from the abdominal aorta under anesthesia for assaying the levels of serum BLA, chemokine ligand CXCL9 and ß-endorphin (EP) by ELISA. Bilateral quadriceps femoris were sampled for observing histopathological changes after staining with conventional H.E. technique, and for detecting the expression levels of phosphorylated AMP-activated protein kinase (p-AMPK) and peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α) by using immunohistochemistry. RESULTS: Compared with the blank control group, the number of rearing and horizontal grid-crossing times, struggling times of tail suspension test were significantly decreased (P<0.05), and the immobility time was obviously prolonged (P<0.05) in the model group. Compared with the model group, both HCSM and medication groups had a significant increase of rearing, horizontal grid-crossing times and struggling times (P<0.05), and the immobility time had a significant decrease (P<0.05). But there were no significant differences in the total movement distance among the 5 groups (P>0.05), and in the 5 indexes of behavioral measurements between the HCSM and medication groups (P>0.05). The sham HCSM could also evidently increase the struggling times and reduce the immobility time (P<0.05). The contents of serum BLA, CXCL9 and ß-EP were obviously higher in the model group than in the blank control group (P<0.05), as well as remarkably lower in the HCSM and medication groups than in the model group (P<0.05). Whereas the expression levels of muscular p-AMPK and PGC-1α were considerably lower in the model group than in the blank control group (P<0.05), and significantly increased in both HCSM and medication groups relevant to the model group (P<0.05). Compared with the sham HCSM group, the contents of BLA, CXCL9 and ß-EP in serum of the HCSM group and contents of CXCL9, ß-EP in medication group were significantly decreased (P<0.05), and the protein expressions of p-AMPK and PGC-1α in quadriceps femoris in both HCSM and medication groups were significantly increased (P<0.05). H.E. staining showed smaller intercellular space, uneven cytoplasmic staining in some muscle fibers, nucleus pyknosis and condensation, and inflammatory cell infiltration in the model group, which was milder in both HCSM and medication groups. CONCLUSION: HCSM can mitigate the stress behavioral state in CFS rats, which may be related with its functions in lowering the levels of serum BLA, CXCL9 and ß-EP, and activating AMPK/PGC-1α signaling pathway (balancing energy metabolism) in the quadriceps femoris.

Licochalcone B induces DNA damage, cell cycle arrest, apoptosis, and enhances TRAIL sensitivity in hepatocellular carcinoma cells.

Hepatocellular carcinoma (HCC) is a highly fatal disease recognized as a growing global health crisis. Traditional Chinese herbal medicines have been used to treat patients with cancer for many years in China. This study investigated the effects of licochalcone B (LCB), a flavonoid compound isolated from the root of Glycyrrhiza uralensis Fisch., on cell proliferation, DNA damage and TNF-related apoptosis-inducing ligand (TRAIL)-mediated apoptosis in HCC cells. Our results showed that LCB inhibited cell proliferation and induced DNA damage, cell cycle arrest and apoptosis. Treatment with LCB significantly inhibited the Akt/mTOR pathway and activated endoplasmic reticulum (ER) stress and mitogen-activated protein kinase (MAPK) signaling pathway. Moreover, combined treatment with LCB and TRAIL yielded evident enhancements in the viability reduction and apoptosis. LCB upregulated death receptor 4 (DR4) and death receptor 5 (DR5) protein in a concentration- and time-dependent manner. The knockdown of DR5 significantly suppressed TRAIL-induced cleavage of PARP, which was enhanced by LCB. Treatment with an extracellular-regulated kinase (ERK) inhibitor (PD98059) or c-Jun N-terminal kinase (JNK) inhibitor (SP600125) markedly reduced the LCB-induced upregulation of DR5 expression and attenuated LCB-mediated TRAIL sensitization. In summary, LCB exhibits cytotoxic activity through modulation of the Akt/mTOR, ER stress and MAPK pathways in HCC cells and effectively enhances TRAIL sensitivity through the upregulation of DR5 expression in ERK- and JNK-dependent manner. Combination therapy with LCB and TRAIL may be an alternative treatment strategy for HCC.

[Clinical efficacy and safety evaluation of acupuncture combined with moxibustion in treatment of allergic rhinitis].

OBJECTIVE: To evaluate the clinical efficacy and safety of acupuncture combined with moxibustion on allergic rhinitis. METHODS: Using the random number table, 80 patients with allergic rhinitis were divided into a medication group and an acupuncture combined with moxibustion (acu-mox) group, 40 cases in each one. In the medication group, ioratadine tables were prescribed for oral administration, one tablet daily for 10 days as 1 session , 3 sessions of treatment were required. In the acupuncture combined with moxibustion group, bilateral Yingxiang (LI20), Yintang (EX-HN3), bilateral Hegu (LI4) and bilateral Shenshu (BL23) were selected as the main points and stimulated with acupuncture and moxibustion; and the acupoint prescription was modified according to symptoms. This combined treatment was given once every day, stimulating for 30 min each time, and 10 treatments made 1 course, for 3 courses of treatment totally. Before and after treatment, the scores for symptoms and physical signs, as well as the score of rhino-conjunctivitis related quality of life scale (R-QOL) were evaluated separately. The sample of the inferior turbinate mucosa tissue was collected and the distribution of eosinophil (EOS) was scored using HE staining and Sheldeny evaluation. Using enzyme-linked immunosorbent assay (ELISA), the contents of serum immunoglobulin E (IgE), retinoic-acid-receptor-related orphan nuclear receptor γt (RORγt), forkhead box protein P3 (Foxp3), interleukin-17 (IL-17), IL-27 and IL-33 were determined. The clinical efficacy was evaluated in the patients with allergic rhinitis of two groups and all the adverse reactions were recorded during treatment. RESULTS: The scores of symptoms and physical signs as well as the score of R-QOL, and EOS distribution score and the contents of serum IgE, RORγt, IL-17 and IL-33 were all reduced as compared with those before treatment in each group (P<0.05), and the contents of serum Foxp3 and IL-27 were increased as compared with those before treatment in each group (P<0.05). After treatment, the scores of symptoms and physical signs as well as the score of R-QOL, and the contents of serum IgE, RORγt and IL-33 in the acu-mox group were lower than those in the medication group (P<0.05), and the contents of serum Foxp3 and IL-27 were higher than those of the medication group (P<0.05). The total effective rate of the acu-mox group was 100.0% (40/40), significantly higher than 82.5% (33/40) in the medication group (P<0.05). No ob-vious adverse reaction was found in either group during and after treatment. CONCLUSION: Acupuncture combined with moxibustion is significantly effective and safe in treatment of allergic rhinitis. Its effect mechanism may be related to the balance modulation of Th1/Th2 and Th17/Treg cells mediated by naive CD4+T cells.

Connotation and Clinical Application of Tong （Dredging） Method in Treatment of Coronary Heart Disease / 中国实验方剂学杂志

Tong （dredging） method in traditional Chinese medicine （TCM） emphasizes soothing the stagnated Qi， blood， and body fluid in zang-fu organs， meridians， and collaterals to remove pathogens， reinforce vital Qi， and balance Yin and Yang of the human body. Tong method can be adopted to disperse sweat pore， attack pathogenic Qi， harmonize Yin and Yang， as well as tonify deficiency， and resolve stagnation. It has been proved effective in treating coronary heart disease （CHD）， which falls into the category of "chest impediment and heart pain" in TCM， with the key pathogenesis lying in blood vessel obstruction. Therefore， dredging blood vessels is the primary therapeutic principle for CHD. Specifically， there are four aspects. The first is dispersing and dredging the sweat pore of the heart. If the sweat pore is occluded by pathogenic cold， which makes Yang-qi undissipated， Cinnamomi Ramulus， Piperis Longi Fructus， Alpiniae Officinarum Rhizoma， and Asari Radix et Rhizoma can be prescribed for warming and dredging heart Yang. If the Yang-qi of the heart and chest stagnated in the body， which hinders Qi and blood to nourish the myocardium， resulting in chest pain， Poria and Alismatis Rhizoma can be prescribed. For CHD due to atherosclerosis and inflammation， heat-clearing， toxin-removing， and inflammation-resisting Chinese medicinal herbs such as Coptidis Rhizoma and Rhei Radix et Rhizoma are recommended. The second is attacking and dredging the collaterals of the heart. Salviae Miltiorrhizae Radix et Rhizoma， Chuanxiong Rhizoma， Notoginseng Radix et Rhizoma， etc. can be prescribed for blood stasis， Trichosanthis Fructus， Allii Macrostemonis Bulbus， Pinelliae Rhizoma， etc. for phlegm， and Aquilariae Lignum Resinatum， Euodiae Fructus， etc. for pathogenic cold. Since the chronic disease can affect collaterals， Moschus and Santali Albi Lignum can be added to promote blood circulation and remove the obstruction of collaterals of the heart. The third is harmonizing and dredging the mind. Cinnamomi Ramulus， Coptidis Rhizoma， Cinnamomi Cortex， etc. are selected for restoring the coordination between the heart and the kidney. According to the specific syndrome， the methods of nourishing the mind and calming the nerves through tranquilizing the mind， calming down the mind， and inducing resuscitation can be selected using such Chinese medicines as Ziziphi Spinosae Semen， Polygalae Radix， and Draconis Ossa. The fourth is tonifying and dredging the Qi and blood of the heart. The deficiency syndrome of CHD is divided into Qi deficiency and kidney deficiency. Invigorating Qi and strengthening the heart are the first essentials for the treatment of CHD. In Qi invigoration， Qi and blood must be strengthened simultaneously to strengthen the heart and clear the pulse. Hence， Bazhentang modified by Salviae Miltiorrhizae Radix et Rhizoma and Carthami Flos can be chosen. In kidney Qi tonifying， kidney and heart must be strengthened simultaneously， and the methods of tonifying kidney and activating blood can be used. Ginseng Radix et Rhizoma and Astragali Radix are considered as the first choice for tonifying heart Qi， and Epimedii Folium and Morindae Officinalis Radix for tonifying kidney Qi， which are added with Salviae Miltiorrhizae Radix et Rhizoma and Rehmanniae Radix Praeparata to obtain the kidney-tonifying and blood-activating prescription. It is suitable for treating CHD due to kidney deficiency and blood stasis. Simultaneous treatment of heart and kidney is more suitable for middle-aged and elderly patients and chronically ill patients. Tong method can be used in various clinical diseases as well as CHD.

ObjectiveTo evaluate the clinical efficacy and safety of Yangxin Dawayimicol honey ointment （YDHO） in the treatment of insomnia with the syndrome of Qi stagnation and blood stasis. MethodEighty insomnia patients who met the inclusion criteria in the Department of Encephalopathy of the Third Affiliated Hospital of Henan University of Chinese Medicine from November 2019 to October 2020 were randomly divided into an experimental group （48 cases） and a control group （32 cases）. The experimental group was treated with YDHO + Xuefu Zhuyu capsule simulators，and the control group was treated with Xuefu Zhuyu capsules + YDHO simulators for eight weeks. The changes in Pittsburgh sleep quality index（PSQI）score，traditional Chinese medicine （TCM） syndrome score，insomnia severity index （ISI），neurotransmitter indexes ［γ-aminobutyric acid（GABA），glutamic acid（Glu），and 5-hydroxy tryptamine（5-HT）］，serum inflammatory indexes ［interleukin-6（IL-6）and interleukin-10（IL-10）］， and safety index of the two groups were compared. ResultThe total effective rate was 97.83%（45/46） in the experimental group， higher than 68.75%（22/32） in the control group（Z=-4.292，P<0.01）. The experimental group was superior to the control group in PSQI score，ISI score，TCM syndrome score， and sleep duration（P<0.05）. The curative effects were equivalent between the two groups in shortening the time to fall asleep. The experimental group showed increased serum content of GABA，5-HT， and IL-10 and reduced content of Glu and IL-6，with few adverse reactions （P<0.05）. ConclusionYDHO is effective，safe， and reliable in the treatment of insomnia with Qi stagnation and blood stasis syndrome.
