Review
The changing composition of gut microbiota, much like aging, accompanies people throughout their lives, and the inextricable relationship between both has recently attracted extensive attention as well. Modern medical research has revealed that a series of changes in gut microbiota are involved in the aging process of organisms, which may be because gut microbiota modulates aging-related changes related to innate immunity and cognitive function. At present, there is no definite and effective method to delay aging. However, Nobel laureate Tu Youyou's research on artemisinin has inspired researchers to study the importance of Traditional Chinese Medicine (TCM). TCM, as an ancient alternative medicine, has unique advantages in preventive health care and in treating diseases as it already has formed an independent understanding of the aging system. TCM practitioners believe that the mechanism of aging is mainly deficiency, and pathological states such as blood stasis, qi stagnation and phlegm coagulation can exacerbate the process of aging, which involves a series of organs, including the brain, kidney, heart, liver and spleen. Our current understanding of aging has led us to realise that TCM can indeed make some beneficial changes, such as the improvement of cognitive impairment. However, due to the multi-component and multi-target nature of TCM, the exploration of its mechanism of action has become extremely complex. While analysing the relationship between gut microbiota and aging, this review explores the similarities and differences in treatment methods and mechanisms between TCM and Modern Medicine, in order to explore a new approach that combines TCM and Modern Medicine to regulate gut microbiota, improve immunity and delay aging.

BACKGROUND
Airway mucus plugs are frequently identified on CT scans of patients with COPD with a smoking history without mucus-related symptoms (ie, cough, phlegm [silent mucus plugs]).
RESEARCH QUESTION
In patients with COPD, what are the risk and protective factors associated with silent airway mucus plugs? Are silent mucus plugs associated with functional, structural, and clinical measures of disease?
STUDY DESIGN AND METHODS
We identified mucus plugs on chest CT scans of participants with COPD from the COPDGene study. The mucus plug score was defined as the number of pulmonary segments with mucus plugs, ranging from 0 to 18, and categorized into three groups (0, 1-2, and ≥ 3). We determined risk and protective factors for silent mucus plugs and the associations of silent mucus plugs with measures of disease severity using multivariable linear and logistic regression models.
RESULTS
Of 4,363 participants with COPD, 1,739 had no cough or phlegm. Among the 1,739 participants, 627 (36%) had airway mucus plugs identified on CT scan. Risk factors of silent mucus plugs (compared with symptomatic mucus plugs) were older age (OR, 1.02), female sex (OR, 1.40), and Black race (OR, 1.93) (all P values < .01). Among those without cough or phlegm, silent mucus plugs (vs absence of mucus plugs) were associated with worse 6-min walk distance, worse resting arterial oxygen saturation, worse FEV % predicted, greater emphysema, thicker airway walls, and higher odds of severe exacerbation in the past year in adjusted models.
INTERPRETATION
Mucus plugs are common in patients with COPD without mucus-related symptoms. Silent mucus plugs are associated with worse functional, structural, and clinical measures of disease. CT scan-identified mucus plugs can complement the evaluation of patients with COPD.

Review
Euphorbia helioscopia L. which is called "Zeqi" in China, is a medicinal plant extensively distributed worldwide, especially in China, and has been widely used for decades to treat various diseases including edema, phlegm and cough, malaria, dysentery, scab, tuberculous fistula, osteomyelitis, and cancer. The present review aims to provide up-to-date information on E. helioscopia, including its traditional uses, phytochemistry, quality control, pharmacological research, toxicology, and human studies in exploring future scientific and therapeutic potentials in disease treatment. So far, a total of 173 terpenoids, as well as polyphenols, steroids, lipids, and volatile oils have been isolated and identified from E. helioscopia. Among them, diterpenoids and flavonoids are the most important and abundant bioactive constituents. Modern pharmacological studies have demonstrated that E. helioscopia has outstanding bioactivities especially on antiproliferative and multidrug resistance modulating. Nevertheless, most of these studies were carried out in vitro. The quality control, metabolites identification, in-depth in-vivo studies as well as toxicology and human studies for the crude extracts and active components are still very limited. Consequently, more well-designed pre-clinical and clinical studies are required to justify their reported therapeutic potential.

Review
As a multifactorial degenerative disease, Parkinson disease (PD) causes tremor, gait rigidity, and hypokinesia, which interfere with normal life. Because the disease is usually discovered in the late stage of complete degeneration of neurons, it can greatly delay treatment and even eventually lead to death. Therefore, the diagnosis of this disease is very challenging, and it is gratifying that substantial progress has been made in the development of optical coherence tomography (OCT) as a diagnostic biomarker for this disease, and genetic and imaging tests have become part of routine protocols in clinical practice. In the cognition of traditional Chinese medicine (TCM), this disease belongs to deficiency in origin and excess in superficiality, which is always caused by deficiency of liver and kidney, deficiency of qi and blood, and is closely related to wind, fire, phlegm and blood stasis. A large number of studies have shown that TCM can effectively treat motor and non-motor symptoms of PD, combat oxidative stress and reduce inflammatory response, and improve the quality of life of patients. Based on the pathophysiological mechanism of PD, this paper discusses the treatment of PD by TCM acupuncture combined with medicine based on syndrome differentiation.

Meta-Analysis Review
ETHNOPHARMACOLOGICAL RELEVANCE
Many researchers have adopted resolving phlegm and unblocking fu-organs (RPUF) therapy for acute ischemic stroke (AIS) patients and yielded beneficial results in terms of clinical symptoms. However, there has been no systematically pooled analysis of RPUF therapy for AIS to date. Therefore, a well-designed systematic review and meta-analysis is necessary.
AIM
This systematic review aims to determine the efficacy and safety of traditional Chinese medicine (TCM) therapy for resolving phlegm and unblocking fu-organs (RPUF) for the treatment of acute ischemic stroke (AIS).
METHODS
Eight databases were searched to identify eligible randomized controlled trials (RCTs) involving RPUF therapy for AIS. The primary outcome included the modified Rankin Scale (mRS), and the secondary outcomes were the National Institute of Health Stroke Scale (NIHSS), the Neurological Deficit Score (NDS), Barthel Index (BI), Fugel-Meyer assessment (FMA), and the Glasgow Coma Scale (GCS). The Cochrane Handbook for Systematic Reviews of Interventions was used to assess risk of bias. The quantitative synthesis was analyzed using RevMan 5.3 and Stata 14.0 software.
RESULTS
The systematic review and meta-analysis comprised 61 RCTs with a total of 6056 participants. RPUF prescriptions combined with usual care were superior to usual care alone in individuals with AIS, as evidenced by decreased mRS (MD=-0.34; 95%CI [-0.65, -0.03]; P=0.03), NIHSS (MD=-3.38; 95%CI [-4.07, -2.68]; P<0.00001), and NDS (MD=-3.65; 95%CI [-4.07, -3.24]; P<0.00001), as well as improved BI (MD=10.4; 95%CI [8.21, 12.59]; P<0.00001), FMA (MD=20.41; 95%CI [17.40, 23.41]; P<0.00001), and GCS (MD=3.08; 95%CI [1.95, 4.20]; P<0.00001). No significant difference was observed in the incidence of adverse effects between the RPUF therapy group and the usual care group.
CONCLUSION
RPUF therapy appears to be an effective and safe approach for treating AIS; it could decrease mRS, NIHSS, and NDS while improving BI, FMA, and GCS. However, the methodological quality of the included RCTs was far from sufficient, and further high-quality, well-designed RCTs with long-term follow-up are still required.

Meta-Analysis
Effect of Traditional Chinese Medicine combined with Western Medicine on blood lipid levels and inflammatory factors in patients with angina pectoris in coronary heart disease identified as intermingled phlegm and blood stasis syndrome: a network Meta-analysis.
OBJECTIVE
To evaluate the clinical efficacy of Traditional Chinese Medicine prescriptions for resolving phlegm in the treatment of angina pectoris of phlegm-stasis coronary heart disease by a network Meta-analysis.
METHODS
Randomized controlled trials (RCTs) on clinical efficacy of CHD angina pectoris with interaction of phlegm and blood stasis were searched in PubMed, Springer, the Cochrane Library and Chinese-language databases China National Knowledge Infrastructure, China Science and Technology Journal Database, and Wanfang Data from their inception to December 2021. Literature was screened and literature bias risk was assessed by RevMan5.4 software. The overall response rate, the duration of angina attack, the levels of serum lipids such as total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), and high density lipoprotein cholesterol (HDL-C), and expression of hypersensitive C-reactive protein (hs-CRP) were selected as outcome indicators for network Meta-analysis and mapped using Stata15.1 software.
RESULTS
Totally, 26 RCTs were included, involving 2098 participants. There were 6 TCM formulas with the effects of dispelling phlegm and removing blood stasis. Taking conventional Western Medicine as the common intervention measures, the results showed that the overall response improvement rate from high to low was displayed as modified Xiaoxianxiong decoction (, MXD), Danlou tablet (, DT), modified Gualou Xiebai Banxia decoction (, MGXBD), modified Wendan decoction (, MWD), modified Zhishi Xiebai Guizhi decoction (, MZXGD), and modified Erchen decoction (, MED). The sequence of angina attack duration improvement from high to low was MZXGD, MGXBD, DT, MWD, MXD. The sequence of TC improvement from high to low was MZXGD, MED, DT, and MGXBD. Sequence of improving TG from high to low was MED, MZXGD, MGXBD, and DT. For LDL-C improvement, the effect from good to poor was MZXGD, MGXBD, DT, and MED. With regard to HDL-C improvement, the effect was ranked as MED, MZXGD, MGXBD, and DT from good to poor. hs-CRP expression from high to low was MZXGD, MXD, MED, MWD, and MGXBD.
CONCLUSION
TCM formula with the effects of dispelling phlegm and removing blood stasis combined with conventional Western Medicine has obvious advantages in treating CHD angina pectoris with interaction of phlegm and blood stasis. MZXGD has great potential in increasing the overall response rate, reducing Duration of angina attack improving blood lipids, and reducing inflammatory factors. However, due to the limitations of extant studies, the conclusions of this study need to be confirmed by numerous reasonably-designed RCTs.

Review
BACKGROUND
Parkinson's disease (PD) is the second most common neurodegenerative disease with no treatment currently available to modify its progression. Traditional Chinese medicine (TCM) has gained attention for its unique theoretical basis and clinical effects. Many studies have reported on the clinical effects and pharmacological mechanisms of Chinese herbs in PD. However, few studies have focused on the treatment mechanisms of anti-PD TCM drugs from the perspective of TCM itself.
PURPOSE
To elaborate the treatment mechanisms of anti-PD TCM drugs in the perspective of TCM.
METHODS
We performed a literature survey using traditional books of Chinese medicine and online scientific databases including PubMed, Web of Science, Google Scholar, China National Knowledge Infrastructure (CNKI), and others up to July 2021.
RESULTS
TCM theory states that PD is caused by a dysfunction of the zang-fu organs (liver, spleen, kidney, and lung) and subsequent pathogenic factors (wind, fire, phlegm, and blood stasis). Based on the pathogenesis, removing pathogenic factors and restoring visceral function are two primary treatment principles for PD in TCM. The former includes dispelling wind, clearing heat, resolving phlegm, and promoting blood circulation, while the latter involves nourishing the liver and kidney and strengthening the spleen. The anti-PD mechanisms of the active ingredients of TCM compounds and herbs at different levels include anti-apoptosis, anti-inflammation, and anti-oxidative stress, as well as the restoration of mitochondrial function and the regulation of autophagy and neurotransmitters.
CONCLUSION
Chinese herbs and prescriptions can be used to treat PD by targeting multiple pharmacological mechanisms.

Randomized Controlled Trial
BACKGROUND
Traditional Chinese medicine (TCM) theories assert that body constitution and meridian energy lay the foundation for disease prevention. TCM-based health concepts have not yet been incorporated into mobile health (mHealth) apps for individuals with prediabetes.
OBJECTIVE
The aim of this study was to examine the effectiveness of a TCM mHealth app for individuals with prediabetes.
METHODS
This randomized controlled trial recruited 121 individuals with prediabetes at a teaching hospital in New Taipei City between February 2020 and May 2021. The participants were randomly assigned to the TCM mHealth app group (n=42), ordinary mHealth app group (n=41), or control group (n=38). All participants received the usual care that included 15-20 minutes of health education about the disease, along with healthy diet and exercise encouragement. The ordinary mHealth app included physical activity (PA), diet, and disease education, along with individual records. The TCM mHealth app additionally included qi and body constitution information, along with constitution-based PA and diet advice. The control group received the usual care alone and did not have access to any app. Data were collected at baseline, at the end of the 12-week intervention, and 1 month after the intervention. Body constitution, including yang-deficiency, yin-deficiency, and phlegm-stasis, was measured according to the Body Constitution Questionnaire, with higher scores indicating a greater deficiency. Body energy was examined using the Meridian Energy Analysis Device. The Short-Form 36 questionnaire was used to evaluate health-related quality of life (HRQOL), which yielded physical component scores and mental component scores, with higher scores indicating better physical and mental aspects of HRQOL, respectively.
RESULTS
Compared to the control group, the TCM mHealth app group showed greater improvement in hemoglobin A (HbA), yang-deficiency and phlegm-stasis body constitution, and BMI; however, no significant differences were found in these outcomes between the TCM mHealth app and ordinary mHealth app groups. The TCM mHealth app group showed better improvement in body energy and mental component scores than the ordinary mHealth app group. There were no significant differences in fasting plasma glucose, yin-deficiency body constitution, Dietary Approaches to Stop Hypertension dietary behavior, and total PA among the three groups after the intervention.
CONCLUSIONS
Use of either the ordinary or TCM mHealth app improved HRQOL among individuals with prediabetes. Compared to the outcomes of controls not using any app, use of the TCM mHealth app was effective at improving HbA, BMI, yang-deficiency and phlegm-stasis body constitution, and HRQOL. Moreover, using the TCM mHealth app seemed to improve the body energy and HRQOL more than when using the ordinary mHealth app. Further studies with a larger sample size and longer follow-up period may be necessary to determine whether the differences favoring the TCM app are clinically meaningful.

Review
In western medicine, obstructive sleep apnea hypopnea syndrome (OSAHS) is an increasingly serious public health hazard, which is exacerbated by the obesity epidemic and an aging population. Ancient medical literature of traditional Chinese medicine (TCM) also recorded OSAHS-like symptoms but described the disease from a completely distinct theoretical perspective. The earliest records of snoring in ancient China can be traced back 2500 years. In TCM, the pathogenesis of OSAHS can be attributed mainly to turbid phlegm and blood stasis. Various TCM prescriptions, herbal medicines, and external therapy have also been proposed for the prevention and therapy of OSAHS. Some of these strategies are still used in current clinical practice. This review highlights historical characterizations of OSAHS and the theory of TCM and also explores its therapy in TCM, which may shed light on future OSAHS research. This is the first systematic English review of the role of TCM in the treatment of OSAHS.

PURPOSE
Occupational exposure to dust has been recognised as a significant health hazard to mine workers. This study aimed to investigate the association between exposure to inhalable (INH) and respirable (RES) dust and respiratory health among mine workers in Western Australia using an industry-wide exposure database.
METHODS
The database comprised cross-sectional surveys conducted by mining companies for the period 2001-2012. The study population consisted of 12,797 workers who were monitored for exposure to INH and RES dust and undertook health assessments including a respiratory questionnaire and spirometry test.
RESULTS
Despite the general trend of declining exposure to both INH and RES dust observed over the 12 years period, mine workers reported a higher prevalence of phlegm and cough when exposed to elevated concentrations of INH and RES dust. Logistic regression analysis further confirmed the positive association between INH dust exposure and the prevalence of phlegm with an adjusted odds ratio of 1.033 (95% CI 1.012-1.052). Overall, 6.3% of miners might have potential airway obstruction, and exposure to INH dust was associated with impaired lung function parameters.
CONCLUSION
Exposure levels of INH and RES dust particles among mine workers have reduced considerably and were well below currently legislated occupational exposure limits. However, given the reported higher prevalence of phlegm and cough among those with elevated dust concentrations, there is a continued need for effective dust exposure monitoring and control in the mineral mining industry.
