RESUMEN

The accumulation and aggregation of α-synuclein (α-syn) is the main pathologic event in Parkinson's disease (PD), dementia with Lewy bodies, and multiple system atrophy. α-Syn-seeded fibril formation and its induced toxicity occupy a major role in PD pathogenesis. Thus, assessing compounds that inhibit this seeding process is considered a key towards the therapeutics of synucleinopathies. Using biophysical and biochemical techniques and seeding-dependent cell viability assays, we screened a total of nine natural compounds of alkaloid origin extracted from Chinese medicinal herbs. Of these compounds, synephrine, trigonelline, cytisine, harmine, koumine, peimisine, and hupehenine exhibited in vitro inhibition of α-syn-seeded fibril formation. Furthermore, using cell viability assays, six of these compounds inhibited α-syn-seeding-dependent toxicity. These six potent inhibitors of amyloid fibril formation and toxicity caused by the seeding process represent a promising therapeutic strategy for the treatment of PD and other synucleinopathies.

RESUMEN

BACKGROUND: During COVID-19, the public actively sought non-pharmacological and self-management approaches to prevent infection. Little is known on the use of traditional, complementary and integrative medicine (TCIM) by the public as preventive measures. This study investigated the prevalence and patterns of TCIM use during the pandemic, and identified factors associated with its use among the general population in Hong Kong. METHODS: An online cross-sectional survey was conducted from November to December 2020. The survey solicited information on the respondents' sociodemographic characteristics, risk perception of the pandemic, and use of TCIM before and during the pandemic. Logistic regression analysis was conducted to determine predictors of TCIM use. RESULTS: In total, 632 responses (completion rate = 88.1%) were analyzed. TCIM was used by 44.0% of respondents during the pandemic. The most popular forms of TCIM were vitamins or other dietary supplements (n = 160, 25.3%) and Chinese herbal medicine (n = 122, 19.3%) during the pandemic. The most frequently reported indication was strengthening the immune system, especially for vitamins or other dietary supplements (n = 142/160, 88.8%). Respondents who reported using TCIM were more likely to be female (adjusted odds ratio [aOR] = 1.82, 95% confidence interval [CI] = 1.29-2.59), had higher education attainment (aOR = 2.21, 95% CI = 1.39-3.59), and older-aged (age >55 years: aOR = 1.77, 95% CI = 1.04-3.02). Respondents who resided in districts with moderate to high number of confirmed COVID-19 cases (aOR = 1.60, 95% CI = 1.07-2.42) and had a higher level of risk perception (aOR = 1.04, 95% CI = 1.01-1.07) were also more likely to use TCIM. CONCLUSION: TCIM was used commonly in Hong Kong during the COVID-19 pandemic. While vaccination and social distancing remain the mainstay of controlling the pandemic, professional bodies should proactively consider public preferences and provide information regarding the effectiveness and safety of TCIM for COVID-19 prevention and treatment.

RESUMEN

ABSTRACT: To explore the possible molecular mechanism of reproductive toxicity of Tripterygium wilfordii from the perspective of network pharmacology and bioinformatics.The compounds of T wilfordii were obtained by querying the relevant Chinese medicine database, the effective compounds were screened and the corresponding targets were obtained, and then compared with the reproductive toxicities related to disease targets obtained from the disease gene database to infer the potential toxic targets of reproductive toxicity of T wilfordii. Then, the key targets of reproductive toxicity of T wilfordii were screened using Search Tool for the Retrieval of Interacting Genes/Protein and Cytoscape. The gene ontology function and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, as well as module analysis, were performed on the key targets using Database for Annotation, Visualization, and Integrated Discovery and Cytoscape, respectively. Finally, the network between effective compounds-toxic targets was conducted to see how the compounds interacted.A total of 48 effective compounds and 482 potential toxic targets related to the reproductive toxicity of T wilfordii were screened. The enrichment analysis results showed that the key targets were mainly enriched in biological processes such as response to drug, ionotropic glutamate receptor signaling pathway, and KEGG pathways such as neuroactive ligand-receptor interaction, cAMP signaling pathway. In the protein-protein interaction network of potential toxic targets, there were 78 key targets such as TP53, INS, IL6, AGT, ADCY3, and so on. Enrichment analysis of the top module with 19 genes from module analysis indicated that T wilfordii might cause reproductive toxicity by gene ontology terms and KEGG pathways such as regulation of vasoconstriction, G-protein coupled receptor signaling pathway, inflammatory response, cAMP signaling pathway, and so on. In the network between effective compounds of T wilfordii and key targets, there were 5 compounds with high degree including Tingenone, Wilfordic Acid, Abruslactone A, Nobilin, and Wilforlide B.The complex molecular mechanism of reproductive toxicity of T wilfordii can be preliminarily elucidated with the help of the network pharmacology method, and the analysis results can provide some reference for the further mechanism research of reproductive toxicity of T wilfordii.

RESUMEN

Respiratory syncytial virus (RSV) can cause lower respiratory tract infections, such as bronchiolitis in infants. In China, traditional asthma-relieving medicine has numerous clinical applications in the treatment of RSV infections. However, due to the complexity of the traditional Chinese medicine system, its therapeutic mechanism and main pharmacological components remain unclear. Metabolomics can be used to analyze the efficacy of traditional Chinese medicine to provide modern scientific evidence for such treatments. In this study, an animal model experiment was performed with seven groups of three-week-old rats. The model group and five intervention groups were inoculated nasally with RSV for three consecutive days, and the normal group was treated with the same amount of saline for three consecutive days under the same conditions. In parallel, the five intervention groups were treated separately with the following via intragastric administration for seven consecutive days: asthma-relieving traditional Chinese medicine decoction, its three constituent agents (ascending (xuan) therapy, descending (jiang) therapy, pyretic clearing (qing) therapy), and ribavirin. Both normal group and RSV model group were administered with normal saline via intragastric administration as controls for seven consecutive days. The fundus plasma of rats in each group was collected on day 0, day 3, and day 7. Liquid chromatography-mass spectrometry-based untargeted metabolomics analysis was performed to investigate the changes in the metabolome after RSV infection, the effects of the asthma-relieving decoction on the regulation of metabolites related to RSV infection, and the primary source of efficacy. The detected metabolite ions were corrected using internal standards. Multivariate analysis of ions with an RSD value of less than 30% in quality control (QC) samples was used to construct principal component analysis models to monitor the overall metabolic changes of each group. The results showed that, during RSV infection and treatment, the asthma-relieving decoction and the positive control ribavirin had similar effects on the overall metabolic regulation of RSV-infected rats. Among the three asthma-relieving decoction constituent agents, the ascending (xuan) therapy agents which was composed of ephedra and ginkgo had a closer metabolic regulation effect with asthma-relieving decoction, and might be the main source of pharmacological efficacy. Based on the retention time, m/z value and tandem mass spectra in the database established by our laboratory, a total of 150 metabolites were identified. Paired t-tests were performed using data of the identified metabolites before and after RSV infection in each group, and it was found that 83 metabolite levels significantly changed after RSV infection, indicating that RSV infection could lead to disorders of multiple metabolic pathways in rats. The altered pathways included aminoacyl-tRNA biosynthesis, phenylalanine, tyrosine, and tryptophan biosynthesis, primary bile acid biosynthesis, phenylalanine metabolism and sphingomyelin metabolism. On the third day, the asthma-relieving decoction had regulatory effects on several metabolites such as bile acids, amino acids, organic acids, lipids, etc. Among the three asthma-relieving decoction constituent agents, the ascending (xuan) therapy agents had more similar effects on the regulation of metabolites with the asthma-relieving decoction. On the other hand, the descending (jiang) therapy agents and pyretic clearing (qing) therapy agents down-regulated the abnormal increase in acylcarnitine caused by the RSV infection. Additionally, both asthma-relieving decoction and its constituent agents could maintain the stability of the immune system and metabolism of the intestinal flora in rats. This study used metabolomics to evaluate the efficacy of an asthma-relieving decoction and demonstrate the metabolites and the corresponding changes after asthma-relieving decoction-based treatment. It provides theoretical support for research on the therapeutic mechanism and active ingredients of asthma-relieving decoction.

RESUMEN

The relevant provisions of bloodletting for expelling pathogens are collected from the works of the medical representative scholars in Jin-Yuan Dynasties and Ming-Qing Dynasties respectively to construct the databases of bloodletting for expelling pathogens of Jin-Yuan Dynasties and Ming-Qing Dynasties. Using frequency analysis, the bloodletting device, bloodletting location, bloodletting volume, the related pathogens and indications are compared between these two times so that the evidences could be provided for the inheritance and development of the academic thought of bloodletting for expelling pathogens. It is found that the three-edge needle is the most commonly used device for bloodletting in Jin-Yuan Dynasties and Ming-Qing Dynasties and yang meridians and local affected area are generally selected for bloodletting. The range of meridian and acupoint selection in Ming-Qing Dynasties are more extensive than those in Jin-Yuan Dynasties, while bloodletting volume is less than that in Jin-Yuan Dynasties. In Jin-Yuan Dynasties, bloodletting therapy is mainly for expelling exogenous pathogens i.e. heat, fire and wind, while, in Ming-Qing Dynasties, this therapy is specially for clearing heat and removing stasis. The disorders of internal medicine are often treated with such therapy in these two dynasties. But, compared with Jin-Yuan Dynasties, the indication of bloodletting therapy is expanded gradually in Ming-Qing Dynasties. It is shown that the academic thought of bloodletting for expelling pathogens in Jin-Yuan Dynasties is inherited and developed from Ming-Qing Dynasties.

RESUMEN

BACKGROUND: Rheumatoid arthritis (RA) is a common autoimmune disease that severely impacts quality of life. Currently available medications for the treatment of RA have adverse side effects. Emerging evidence suggests that intradermal acupuncture (IA) is feasible and safe for patients, but its application in RA patients has not been examined. Our study aims to explore the efficacy and safety of IA for the treatment of RA. METHODS: This study is a randomised, sham-controlled, patient-outcome assessor-statistician blind trial that aims to evaluate the effects of IA in patients with RA. We will recruit 132 patients aged ≥ 18 years with a diagnosis of RA. Patients will be randomly allocated with a 1:1 ratio to IA or sham IA groups. Both groups will receive basic treatment and nursing routines for RA. The experimental group will receive actual IA treatment, whereas the control group will receive sham IA treatment. All patients will receive one course of treatment (i.e., four consecutive treatment sessions with an intervening 1-day interval). Primary outcomes will be traditional Chinese medicine (TCM) syndromes before and after a treatment course and Health Assessment Questionnaire (HAQ) scores. Secondary outcomes will be disease activity score 28 (DAS28) and levels of serum C-reactive protein (CRP). Outcome measures will be collected pre- and post-treatment. DISCUSSION: This study aims to provide high-quality evidence for the efficacy and safety of IA for treating RA. In addition, the results will provide references for selection of acupoints for other syndromes in clinical practice. TRIAL REGISTRATION: Chinese Clinical Trial Registry ChiCTR2000038028 .

RESUMEN

BACKGROUND: Currently, coronavirus disease-2019 (COVID-19) is continuously and rapidly circulating, resulting in serious and extensive effects on human health. Due to the absence of antiviral medicine for COVID-19 thus far, there is a desperate need to develop effective medicine. Traditional Chinese medicine (TCM) has been widely applied in the treatment of epidemic diseases in China, with the aim of achieving clinical efficacy and decreasing the use of antibiotics and glucocorticoids. The aim of this study was to evaluate the efficacy and safety of Baidu Jieduan granules in treating COVID-19. METHODS/DESIGN: This multicentre, open-label, randomized controlled trial will be conducted in 300 patients with COVID-19. The patients will be randomly (1:1) divided into a treatment group and a control group. All patients will receive standard therapy at the same time. Patients in the experimental group will receive Baidu Jieduan granule treatment twice a day for 14 days. The outcomes will be assessed at baseline and at 3, 5, 7 and 14 days after treatment initiation. The primary outcome will be the rate of symptom (fever, fatigue and coughing) recovery. Adverse events (AEs) will be monitored throughout the trial. DISCUSSION: The study will provide high-quality clinical evidence to support the efficacy and safety of Baidu Jieduan granules in the treatment of moderate COVID-19, and enrich the theory and practice of TCM in treating COVID-19.

RESUMEN

Under the guidance of the theory of "kidney governing reproduction", this study demonstrated the mechanism of six types of ovulatory infertility caused by kidney deficiency and blood stasis, including anovulatory bleeding, polycystic ovary syndrome, hyperprolactinemia, luteinized unruptured follicle syndrome, luteal phase deficiency, and primary ovarian insufficiency. A series of studies have confirmed that integrated Chinese and western medicine can increase the responsiveness of the ovaries to gonadotropins and improve ovarian function by regulating the effects of estradiol(E_2), prolactin(PRL), and reducing follicle-stimulating hormone(FSH), luteinizing hormone(LH), progestin(P), and testosterone(T). It can also improve ovulation rate and pregnancy success rate by promoting follicle development, discharging, and synchronizing endometrial growth. This study illustrated the diagnosis and treatment of ovulatory infertility caused by kidney deficiency and blood stasis with integrated traditional Chinese and Western medicine in the "disease-syndrome-symptom" research mode, and highlighted the traditional Chinese medicine(TCM) idea of differentiating diseases based on syndromes and unique advantages of the combination of disease differentiation and syndrome differentiation, and interpreted TCM principle of "treating different diseases with the same method".

RESUMEN

Hyperprolactinemia(HPRL) is one of the diseases leading to anovulatory infertility, which is a refractory gynecological disease and seriously affects female reproductive function. Professor MA Kun has summarized his experience in clinical and scientific studies for many years. And believes that kidney deficiency is the pathogenesis of HPRL and blood stasis is the dominant pathological manifestation of HPRL and can promote the progress of the disease. In view of this, Professor MA Kun took the therapy of kidney-tonifying and blood-activating as the principle for treating anovulatory infertility caused by HPRL, with soothing the liver and promoting Qi as adjuvant therapies. She has also summarized and refined the prescriptions for tonifying kidney and inducing ovulation, which have a remarkable clinical efficacy.

RESUMEN

In the context of the new era, paying attention to maternal and child health and advocating prenatal and postnatal care can effectively improve the quality of the birth population. Traditional Chinese medicine has a long history of prenatal and postnatal healthcare with rich content, which is the theoretical basis of modern related services. With the social development and the improvement of people's awareness of prenatal and postnatal healthcare, people have gradually shifted the focus of prenatal and postnatal healthcare to the peri-pregnancy stage at present, namely that couples of childbearing age are guided to prepare for pregnancy under the premise of solving their basic diseases. Infertility is a common and refractory disease for women of childbearing age. Ovulation disorder is one of its common pathological mechanisms. Traditional Chinese medicine believes that kidney deficiency is the main cause and pa-thogenesis of anovulation infertility and blood stasis is an important factor throughout the disease course. In clinical practice, therapies for invigorating kidney and activating blood are safe and reliable to treat anovulatory infertility mainly by adjusting the hypothalamus-pituitary-ovarian axis, improving ovarian function, uterine environment and gamete quality and increasing endometrial volume. Under the guidance of the thought of prenatal and postnatal healthcare, the authors tried to explore the effect of therapies for kidney-tonifying and blood-activating in the treatment of anovulatory infertility in eugenics, with the purpose of providing ideas and basis for subsequent relevant clinical studies and contributing to prenatal and postnatal healthcare services.

RESUMEN

Pelvic inflammatory disease(PID) has become one of the leading causes of female infertility, with an increasing incidence in recent years. Modern medicine believes that risk factors of PID will affect the formation of eggs and embryo implantation, especially on the encounter of gametes, fertilization, and transport of fertilized eggs to the uterine cavity. Therapies for infertility due to PID include medication, sonographic hydrotubation, surgery, and assisted reproductive technology. Professor Ma Kun believes that the disease is located in the uterus with appendages with the main pathogenesis of kidney deficiency and blood stasis. Blood stasis is the pathological basis, and kidney deficiency is the fundamental pathogenesis, which exhibits deficiency-excess in complexity. Kidney deficiency will cause blood stasis over time, while blood stasis will aggravate kidney deficiency in turn, making PID-induced infertility refractory. In clinical practice, basic therapies follow the principles of kidney-tonifying and blood-activating, removing blood stasis, dredging collaterals, and coordinating thoroughfare and conception vessels. The oral administration of Chinese medicine combined with enema, external application, and external washing displays better efficacy in improving the pelvic microenvironment and increasing the pregnancy rate and pregnancy success rate in the treatment of PID-induced infertility.

RESUMEN

This study used network pharmacology and molecular docking to study the mechanism of Bushen Culuan Formula in the treatment of infertility caused by polycystic ovary syndrome(PCOS). The active ingredients and potential drug targets of Bushen Cu-luan Decoction were obtained by searching the Traditional Chinese Medicine System Pharmacology(TCMSP) database, and the targets of PCOS by searching GeneCards. After the drug targets and disease targets were corrected by Uniprot, the intersection genes were obtained. STRING database and Cytoscape 3.7.2 were used for protein-protein interaction(PPI) analysis of the intersection genes. The ClueGO plug-in of Cytoscape 3.7.2 was employed to perform gene ontology(GO) enrichment and KEGG pathway enrichment for the intersection genes. Finally, molecular docking of the key active ingredients with the targets of Bushen Culuan Formula was performed using AutoDockVina and MGLtools. A total of 136 active ingredients and 314 drug targets of the decoction were obtained from TCMSP, and 136 disease targets from GeneCards. Finally, 49 drug-disease intersection genes were obtained. GO enrichment found that the genes were mainly involved in the regulation of muscle cell apoptosis, positive regulation of small molecule metabolism, core promoter binding, RNA polymerase Ⅱ regulation of pri-miRNA transcription, negative regulation of transmembrane transport and other biological functions. The enriched KEGG pathways mainly included MAPK, PI3 K-Akt, p53, and HIF-1 signaling pathways. The results of molecular docking showed that quercetin and PTGS2 can bind stably and interact through amino acid residues THR206, TRP387, ASN382, etc. This study preliminarily reveals the multi-component, multi-target, and multi-pathway mechanism of Bushen Culuan Formula in the treatment of PCOS-related infertility, which provides a basis for further research.

RESUMEN

Qixuehe Capsules is a compound Chinese patent medicine developed for treating the disorder of Qi and blood(a common etiology of gynecological disease), which has remarkable effects on smoothing liver and regulating Qi, activating blood circulation, and relieving pain. However, due to its complex prescriptions(15 herbs) and multiple effects, the quality control of Qixuehe Capsules has always been a bottleneck problem limiting its sustainable development. Therefore, this study adopted the traditional Chinese medicine Q-markers quantitative identification system established previously by our research group based on the combination of analytic hierarchy process and entropy weight methods. With the different effects of Qixuehe Capsules as the entry point, the comprehensive scores of chemical ingre-dients in Qixuehe Capsules under the items of effectiveness(smoothing liver and regulating qi, activating blood circulation, and relieving pain), testability and specificity were calculated and integrated, respectively. Subsequently, through the analysis of compatibility relationship of Qixuehe Capsules, 15 active ingredients with high comprehensive scores were found to be the top Q-mar-kers of Qixuehe Capsules, including ferulic acid, quercetin, caffeic acid, kaempferol, rutin, Z-ligustilide, senkyunolide Ⅰ, vanillic acid, protocatechuic acid, chlorogenic acid, rosmarinic acid, senkyunolide A, gallic acid, tetrahydropalmatine and eugenol. Collectively, this study not only provided scientific evidence for further research on the improvement and standardization of quality standards of Qixuehe Capsules but also provided methodological references for the quantitative identification of Q-markers of multi-effect traditional Chinese medicine formulae.

RESUMEN

The mixing process is one of the key operation units for solid preparation of traditional Chinese medicine. The physical properties such as particle size, density and viscosity of the mixture are key factors that need to be controlled, which will directly affect the performance of the preparation molding process and product quality. Subsequent dripping process performance and appearance qua-lity of dripping pills will be affected by dynamic viscosity of materials in the mixing process. Based on this, with mixing process of compound Danshen dripping pills as the object, a feedforward control method for the dripping pill mixing process was established based on the concept of quality by design(QbD). Firstly, critical quality attribute(CQA)-dynamic viscosity, critical material attributes(CMAs)-the moisture content of compound Danshen extract, average molecular weight of polyethylene glycol 6000 and critical process parameter(CPP)-mixing temperature were identified through the analysis of properties for multiple batches of the raw materials and excipients as well as technological mechanism. Then the Box-Behnken experimental design was used to establish the regression model among CMA, CPP and CMA(R■=0.972 0, RMSE =16.24) to obtain the design space. Finally, through the verification of three batches within the design space, the mixing process temperature was adjusted according to the properties of the raw materials and exci-pients to achieve accurate control of the dynamic viscosity attribute. The relative deviation between the actual dynamic viscosity value and the target value was less than 3.0 %. The feedforward control of the mixing process of compound Danshen dripping pills was rea-lized in this study, which can contribute to improving quality consistency of the mixing process intermediates, simultaneously provide a reference for the research on the process quality control of other Chinese medicine dripping pills.

RESUMEN

OBJECTIVE: To evaluate the clinical efficacy and safety of combination of traditional Chinese and Western medicine in the treatment of coronavirus disease 2019 (COVID-19) by Meta analysis. METHODS: The clinical randomized controlled trials (RCT) and cohort studies on the treatment of COVID-19 with combination of Chinese traditional and Western medicine published on CNKI, Wanfang database, VIP database and PubMed were searched by computer from January 2020 to June 2020. Patients in the simple Western medicine treatment group were treated with routine treatment of Western medicine, and the patients in integrated traditional Chinese and Western medicine treatment group were treated with traditional Chinese medicine on the basis of routine treatment of Western medicine. The main outcome was the total effective rate of treatment. The secondary outcome were the antipyretic rate, chest CT recovery rate, lymphocyte count (LYM), C-reactive protein (CRP) level and safety. The Cochrane manual and the Newcastle Ottawa Scale (NOS) were used to evaluate the quality of the literature; the RevMan5.3 software was used to analyze the articles that meets the quality standards, and a funnel chart was drawn to evaluate the total effective publication bias. RESULTS: Thirteen articles were analyzed, including 1 039 COVID-19 patients, 559 in integrated traditional Chinese and Western medicine treatment group and 480 in simple Western medicine treatment group. The results of Meta- analysis showed that compared with the simple Western medicine treatment group, the combination of routine treatment of Western medicine and traditional Chinese medicine Qingfei Paidu decoction, Lianhua Qingwen granule, Shufeng jiedu capsule, Xuebijing injection or Reyanning mixture could significantly improve the total effective rate, antipyretic rate and chest CT recovery rate [total effective rate: odds ratio (OR) = 2.95, 95% confidence interval (95%CI) was 2.10-4.14, P < 0.000 01; antipyretic rate: OR =3.01, 95%CI was 1.64-5.53, P = 0.000 4; chest CT recovery rate: OR = 2.53, 95%CI was 1.83-3.51, P = 0.000 1], increase LYM levels [mean difference (MD) = 0.26, 95%CI was 0.02-0.50, P = 0.03], and reduce of CRP content (MD = -17.68, 95%CI was -33.14 to -2.22, P = 0.02). Based on the funnel chart analysis of 12 articles with total efficiency, the result showed that the funnel chart distribution was not completely symmetrical, indicating that there might be publication bias. CONCLUSIONS: On the basis of routine treatment with Western medicine, combined with traditional Chinese medicine can significantly improve the total effective rate of COVID-19 and improve the laboratory results and clinical symptoms of patients. Compared with the routine treatment of Western medicine alone, the combination of traditional Chinese and Western medicine has better clinical efficacy and safety.

RESUMEN

A novel coronavirus named SARS-CoV-2 is causing the severe acute pneumonia (COVID-19) and rapid spread nationally and internationally, resulting in a major global health emergency. Chinese governments and scientists have implemented a series of rigorous measures and scientific research to prevent and control the SARS-CoV-2 infection. However, there is still no specific antiviral drug or vaccine against SARS-CoV-2. It has been proven that traditional Chinese medicine (TCM) exerts an important role in the prevention and treatment of the COVID-19 caused by SARS-CoV-2 during the outbreak. Although the therapeutic effects of these TCM formulas are attractive, the molecular mechanism of action has not been fully elucidated. An emerging strategy of systems pharmacology has been proposed to be a promising method to interpret drug action in complex biological systems and quickly screen out the bioactive compounds from TCM to treat treatment of COVID-19 caused by SARS-CoV-2. Therefore, in this study, the epidemiology, TCM therapy, and the systems pharmacology-based method for TCM are reviewed for COVID-19 to provide a perspective for the prevention and treatment of SARS-CoV-2 infection. Further efforts should be made to reduce disease burden and improve the ability to design antiviral drugs and vaccines, which will benefit the health care system, economic development and even social stability.

RESUMEN

BACKGROUND: Knee osteoarthritis (KOA) is a common joint disease worldwide, and the main cause of pain and disability in the elderly. Due to increased aging and rates of obesity of the global population, the number of patients with KOA is expected to increase. To reduce the burden of KOA, effective and safe interventions should be developed to reduce pain and improve range of motion, functionality, and quality of life. The aim of the proposed randomized controlled study was to evaluate the efficacy and safety of a traditional Chinese medicine (TCM) rehabilitation therapy in the treatment of KOA. METHODS: This multicenter, randomized, double-blind, parallel group, placebo-controlled trial will include a total of 200 patients with KOA. The enrolled patients will be randomly divided into the experimental group (n=100) and control group (n=100). The experimental group will receive basic treatment plus TCM rehabilitation therapy, while the control group will receive basic treatment plus physiotherapy regimen. Primary endpoints will include clinical efficacy outcomes, visual analog scale, Western Ontario and McMaster Universities Osteoarthritis Index score, and Knee Outcome Survey Activities of Daily Living Scale score. The data will help determine whether TCM rehabilitation therapy is beneficial for the treatment of KOA. DISCUSSION: The results will provide high-quality guidance for the current clinical treatment of KOA, and provide patients with more options for symptom relief. The findings from this study may provide updated evidence concerning the efficacy and safety of TCM for patients with KOA.

RESUMEN

BACKGROUND: Extensive-stage small-cell lung cancer (ES-SCLC) is characterized by extensive metastases, aggressive progression, and poor prognosis. Chemotherapy is applied as a preferred first-line regimen for ES-SCLC, but inadequate for improving its overall survival. Traditional Chinese medicine (TCM) is widely used in the clinical practice of ES-SCLC for its synergy with chemotherapy. However, there is still no substantial evidence to prove that TCM can effectively improve the long-term efficacy of ES-SCLC patients. The study intends to determine whether the TCM with chemotherapy can improve the overall survival (OS) in treating with ES-SCLC when compared with chemotherapy alone. METHOD/DESIGN: A multicenter, randomized, single-blind, placebo-controlled clinical trial will be conducted to determine whether the TCM granules combined with chemotherapy can improve the OS of ES-SCLC. Two hundred seventy participants will randomly receive 4-6 cycles (21 days per cycle) of chemotherapy plus TCM granules or placebo. The primary outcome measure is OS. The secondary outcome measures includes progression-free survival (PFS), objective response rate (ORR), quality of life (QoL), and tumor markers. Visits will be performed at the end of each cycle during the treatment period and then every 3 months in the follow-up period until the patients' death or study completion. DISCUSSION: The study's result will provide a high-level evidence for TCM granules using with chemotherapy on the first-line treatment of ES-SCLC.

RESUMEN

BACKGROUND: Bacterial infection is an important cause of diarrhea in children, potentially leading to malnutrition, growth and development disorders, and even death. Antibiotic abuse and resistance are widespread problems worldwide, especially in China. We therefore designed a study to evaluate the clinical efficacy and mechanism of traditional Chinese medicine in alleviating the effects of antibiotic resistance in childhood bacterial diarrhea and enhancing the sensitivity of pathogenic bacteria to antibiotics. METHODS: This randomized, double-blind, placebo-controlled clinical trial has completed ChiCTR registration. The trial will randomly divide 120 children who meet the inclusion criteria into three groups: experimental group 1 (basic treatment + Gegen Qinlian decoction granules + Erbai drink placebo), experimental group 2 (basic treatment + Erbai drink granules + Gegen Qinlian decoction placebo), and control group (basic treatment + Gegen Qinlian decoction placebo + Erbai drink placebo). The main efficacy indicators will be antibiotic use rate and clinical cure rate, and the secondary efficacy indicators will be time to antibiotic intervention, effective rate, and course of treatment determined after 5 days. The following physical and chemical indicators will be measured: routine blood parameters, procalcitonin, C-reactive protein, electrocardiogram, liver and kidney function, electrolytes, routine urinalysis, routine stool analysis, and stool culture (including drug sensitivity). DISCUSSION: The results of this study may provide an objective clinical basis for the use of traditional Chinese medicine in managing antibiotic-resistant bacterial diarrhea in children, formulating relevant guidelines, and demonstrating the use of traditional Chinese medicine for reducing the use of antibiotics.

RESUMEN

For a long time, Chinese medicine has attached great importance to "pulse diagnosis for patients before acupuncture treatment", which emphasizes the close relationship between pulse diagnosis and acupuncture. Pulse diagnosis information is closely related to acupuncture research and runs through the whole process of diagnosis and treatment. However, the lack of repeatable and quantifiable real-time detection means of pulse diagnosis information has affected the application of pulse diagnosis in acupuncture research. Photo plethysmo graphy (PPG) technology has the advantages of convenient acquisition, low price, non-invasive, easy to use and so on. Under the guidance of TCM diagnosis theory, this paper discussed the principle and characteristics of fingertip volumetric pulse wave, studied its relationship with Cunkou pulse diagnosis, developed a new fingertip blood volumetric pulse wave measuring instrument, explored the acquisition and measurement methods of volumetric pulse wave signal, and proposed the relationship between the measuring instrument and acupuncture research. It can provide basic tools and data analysis and support for acupuncture research.
