Are Published Cancer Care Trial Protocols With Traditional Chinese Medicine Interventions Concordant With SPIRIT-TCM Extension 2018? A Scoping Review on Published Trial Protocols Between 2019 and 2022. Integr Cancer Ther 2024; 23:15347354231223966. [PMID: 38291957 PMCID: PMC10832418 DOI: 10.1177/15347354231223966] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 10/31/2023] [Accepted: 12/15/2023] [Indexed: 02/01/2024] Open
Abstract
BACKGROUND The SPIRIT-TCM Extension 2018 was created to guide the design and reporting of Traditional Chinese Medicine (TCM) clinical trial protocols. This study aims to investigate the extent of concordance with this guideline in the relevant field of cancer care research. METHODS A scoping review of TCM cancer trial protocols published in English and Chinese since January 2019 was conducted. Five major academic databases (MEDLINE, EMBASE, CINAHL, CENTRAL, and China National Knowledge Infrastructure) were searched. Concordance with the SPIRIT-TCM Extension 2018 was assessed by descriptive analysis. RESULTS Fifty-three TCM cancer care trial protocols were identified, comprising 23 acupuncture, 26 Chinese herbal medicine (CHM), and 4 Tai Chi/Qigong (TCQ) interventions. The majority of the checklist items had a low rate of concordance, especially in the reporting of quality control and safety, dosage, TCM diagnostic patterns, possible interactions between Western Medicine and TCM interventions, and TCM-related outcome assessments. CONCLUSIONS Although the SPIRIT-TCM Extension 2018 guideline was established through extensive Delphi consultation, there are low rates of concordance between published TCM cancer care clinical trial protocols with the guideline. Further research is necessary to understand the low rate of concordance and how scientific rigors of reporting can be improved in TCM cancer care research.

Effectiveness of Chinese Herbal Medicine in Postoperative Fatigue Syndrome Following Total Joint Arthroplasty or Hip Fracture Surgery: Evidence from Randomized Controlled Trials. Comb Chem High Throughput Screen 2023; 27:CCHTS-EPUB-136390. [PMID: 38031783 DOI: 10.2174/0113862073258802231107060433] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Revised: 08/31/2023] [Accepted: 10/10/2023] [Indexed: 12/01/2023]
Abstract
BACKGROUND There is no high-quality, evidence-based protocol for the treatment of postoperative fatigue syndrome (POFS) after total joint arthroplasty (TJA) or fracture surgery with Chinese herbal medicine (CHM). PURPOSE The purpose of this study was to explore the efficacy of CHM in the treatment of POFS after TJA or hip fracture surgery (HFS). METHODS We searched six databases to obtain randomized controlled trials (RCTs) of CHM for the treatment of POFS after TJA or HFS. The retrieval time limit was from the establishment of each database to August, 2022. According to the Cochrane Handbook for Systematic Reviews version 5.1, we used RevMan 5.3 to evaluate the quality of the studies. Stata 14.0 software was used to merge and analyze the data. The weighted mean difference (WMD) was the effect estimate for statistical analysis. We also performed subgroup analyses according to different types of surgeries. RESULTS A total of 11 RCTs were included in this study, comprising 430 cases in the CHM group and 432 cases in the control group (CG). The meta-analysis results showed that there was no significant difference in the Brief Profile of Mood States (BPOMS) score (WMD=0.08, 95% confidence interval (CI): -0.29 to 0.45, P=0.688), Christensen Fatigue scale (CHFS) score (WMD = 0.15, 95% CI: -0.09 to 0.39, P=0.214) or Identity-Consequence Fatigue Scale (ICFS) score (WMD=-0.40, 95% CI: -1.84 to 1.05, P=0.589) between the CHM group and the CG on the first postoperative day. The use of CHM significantly reduced the BPOMS score (WMD=-0.85 and WMD=-3.01, respectively), CHFS score (WMD=-1.01 and WMD= -1.45, respectively), and ICFS score (WMD=-3.51 and WMD=-5.26) on postoperative days 3 and 7. Compared with the CG, the CHM group had significantly increased serum transferrin and IgG levels on postoperative days 3 and 7. The subgroup analysis results suggested that the application of CHM in HFS patients improved fatigue symptoms on postoperative days 3 and 7, while the application of CHM to treat POFS in TJA patients had great inconsistency in the evaluation of different indicators. CONCLUSION The application of CHM improved the fatigue status of POFS patients after TJA or HFS and increased the levels of transferrin and IgG in serum, which is conducive to promoting the postoperative rehabilitation process of patients. The subgroup analysis results showed that the application of CHM to intervene in POFS in HFS patients had obvious benefits.

Abstract
BACKGROUND Taiwan's unique health behaviour, such as extensive exposure to Chinese Herbal Medicine (CHM), has introduced a risk of inadvertent doping among competing athletes. Pharmacy professionals have an imperative role in advising athletes on the safe use of medicines. This study provides an overview of anti-doping knowledge and educational needs among pharmacists in Taiwan and examines influencing factors. METHODS A cross-sectional online questionnaire survey consisting of five domains, namely demographic characteristics, source of prohibited substances, identification of prohibited substances, understanding of doping control, and education needs on anti-doping, was distributed to the registered pharmacists in Taiwan. In total, 491 responses were included in the analyses. RESULTS Respondents (65% female, aged 41.9 ± 11.4 years, with 68% having a Bachelor's degree) reported a moderate anti-doping knowledge score of 37.2 ± 4.9, ranging from 21 to 48 (out of 51). Fifteen per cent of them had the experience of being counselled about drug use in sports. Higher knowledge scores were observed in younger respondents, showing an age-dependent effect (p < 0.001). Individuals practising in southern Taiwan (compared to northern Taiwan) and those working at clinics (compared to hospitals) exhibited lower knowledge. Most of the respondents (90%) knew that stimulant ephedrine is prohibited in sports, but few had recognised diuretic furosemide (38%) and CHM (7%) containing β2-agonist higenamine. Approximately 90% of respondents agreed with the need for anti-doping education. CONCLUSIONS This study highlights the heterogeneity of anti-doping knowledge among pharmacy professionals and provides practical relevance in organising future educational topics and research-based activities.

Abstract
SARS-CoV-2 Omicron led to the most serious outbreak of COVID-19 in Hong Kong in 2022. Under the pressure of a high volume of patients and limited medical resources, Chinese herbal medicine (CHM) has been extensively used. This is a case-control study of the infected patients that aims to evaluate the effectiveness of CHM using data extracted from the Hong Kong Baptist University Telemedicine Chinese Medicine Centre database. Patients with COVID-19 confirmed by either a rapid antigen test or a polymerase chain reaction who had completed two consultations and taken CHM within 10 days of the first positive test were included in the study (CHM group, [Formula: see text]). The matched control cases were those who did not take CHM within 10 days of the first positive test and were based on age ([Formula: see text] 3 years), vaccine doses ([Formula: see text] 3 doses, or 3 doses), and gender (no-CHM group, [Formula: see text]). The outcomes included the negative conversion time (NCT, primary outcome), total score of individual symptoms, number of the reported symptoms, and individual symptom disappearance rates. The NCT of the CHM group (median days: 7.0, interquartile range: 6.0-8.0) was significantly shorter than that of the no-CHM group (8.0, 7.0-10.5; [Formula: see text]). CHM treatment significantly reduced the total score of individual symptoms ([Formula: see text]) and the number of the reported symptoms ([Formula: see text]) as compared with that of the no-CHM group. Additionally, the symptom disappearance rates of symptoms such as chills, cough, sputum, dry throat, itching throat, headache, chest tightness, abdominal pain, diarrhea, and fatigue were significantly higher in the CHM group than in the no-CHM group. In conclusion, CHM intervention can significantly reduce NCT and COVID-19 symptoms. Chinese medicine can be accurately prescribed based on a telemedical consultation.

Abstract
Current medical treatments for endometriosis-associated pain (EAP) have limitations, including symptom recurrence and hormonal side effects. For this reason, it is important to elucidate any alternative or complementary treatments available, while Chinese herbal medicine (CHM) shows potential to be this treatment. This study aims to provide evidence for the efficacy and safety of CHM for EAP. Randomized control trials comparing CHM to other treatments for EAP in women with endometriosis were considered eligible, and they were searched for in Medline, Embase, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov, as well as in the Chinese databases Sino-Med and CNKI, from inception to October 2021. Numerous outcomes were put through meta-analysis using a weighted mean difference and a 95% CI, and the results of dichotomous data were presented as a pooled RR with a 95% CI. A total of 34 eligible studies with 3389 participants were included. Compared with no treatment, there was a statistically significant pooled benefit of CHM on dysmenorrhea at the end of 3-month treatment, and these effects continued for 3 months, but not 9 months, after treatment. Compared with conventional therapy, a significant difference was found in the levels of pelvic pain with a lower rate of hot flush and irregular vaginal bleeding at the end of treatment for 3 months, but not after treatment. Comparing combined treatment with CHM and conventional therapy with conventional therapy alone, significant decreases were found in dysmenorrhea, dyspareunia, and pelvic pain after a 3-month treatment cycle, and in dysmenorrhea after a 4-month treatment cycle with a lower hot flash rate. In conclusion, CHM, used alone or in combination with conventional therapies, appears to have benefits in relieving EAP with fewer side effects than traditional treatment.

Abstract
Endometriosis is a chronic, estrogen-dependent condition that causes dysmenorrhea and pelvic pain. Chinese herbal medicine (CHM) has been used for endometriosis for many years in Asian populations. This is a retrospective study in a territory teaching hospital of the China Academy of Chinese Medical Sciences in Beijing, China to compare the short- and long-term effectiveness and safety of CHM for endometriosis associated pain (EAP) before and after CHM treatment. A total of 338 out of 1143 women confirmed with endometriosis by ultrasonogram or surgery within three months received a CHM decoction twice a day for at least 3 and up to 24 months. All data were collected by a Structured Medical Records of Endometriosis (SMRE) in every clinic visit covering the whole treatment period. Pain score, evaluated by Numeric Rating Scale, was significantly decreased from 3rd to 12th month in women with moderate or severe pain. Frequency and severity rating of menstrual symptoms, evaluated by Cox Menstrual Symptom Scale, were significantly decreased in women with any pain level. Psychological changes rated by Self-rating Anxiety Scale (SAS) were significantly lower in 3, 6, 12, and 24 months of treatment, but those by Self-rating Depression Scale (SDS) was significantly decreased in six months of treatment. There was no severe adverse event but only minor side-effects. In conclusion, our study showed that CHM relieved EAP and related symptoms with minimal side-effects after treatment. A large-scale randomized and placebo-controlled trial could be designed to confirm the efficacy and safety.

Abstract
Breast cancer is currently the most common cancer in women, and it accounts for 11.6% of all cancer diagnoses in 2018. Breast cancer patients frequently resort to alternative medicine in addition to conventional Western therapy. This study is to evaluate clinical effectiveness of Chinese herbal medicine (CHM) on breast cancer by conducting meta-analyses on 81 randomized controlled trials (RCTs) with a total of 7215 subjects from eight databases. All RCTs compared patients using Western therapy alone and those using additional CHM therapy to evaluate the difference of primary (tumor response, mean time to progression (mTTP), overall survival (OS) and progression free survival (PFS)) and secondary outcome measures (tumor markers). Results showed that under the RECIST1.1 criteria, 52% patients with additional CHM therapy (67%, under WHO criteria) achieved either a complete response (CR) or a partial response (PR), compared to 38% patients with Western therapy alone (53%, under the WHO criteria). The risk ratio was 1.31 ([Formula: see text] < 0.00001, 95% CI = 1.15-1.50) for patients with CHM plus Western therapy and 1.25 ([Formula: see text] < 0.00001, 95% CI = 1.18-1.98) for those with Western therapy. Moreover, patients with complementary CHM therapy were associated with an mTTP of 2.79 months longer ([Formula: see text] < 0.00001) and an OS of 1.90 months longer ([Formula: see text] < 0.00001); they also had an increase in 3-year PFS ([Formula: see text]= 0.002), 2- ([Formula: see text]= 0.0002) and 5-year ([Formula: see text]= 0.006) OS rates. Therefore, complementary CHM therapy might demonstrate clinical benefits for breast cancer patients in terms of tumor response and survival. Clinical studies with further stratification of tumor stages and intervention types are highly warranted.

Abstract
With the coming of the era of the aging population, hypertension has become a global health burden to be dealt with. Although there are multiple drugs and procedures to control the symptoms of hypertension, the management of it is still a long-term process, and the side effects of conventional drugs pose a burden on patients. Flavonoids, common compounds found in fruits and vegetables as secondary metabolites, are active components in Chinese Herbal Medicine. The flavonoids are proved to have cardiovascular benefits based on a plethora of animal experiments over the last decade. Thus, the flavonoids or flavonoid-rich plant extracts endowed with anti-hypertension activities and probable mechanisms were reviewed. It has been found that flavonoids may affect blood pressure in various ways. Moreover, despite the substantial evidence of the potential for flavonoids in the control of hypertension, it is not sufficient to support the clinical application of flavonoids as an adjuvant or core drug. So the synergistic effects of flavonoids with other drugs, pharmacokinetic studies, clinical trials and the safety of flavonoids are also incorporated in the discussion. It is believed that more breakthrough studies are needed. Overall, this review may shed some new light on the explicit recognition of the mechanisms of anti-hypertension actions of flavonoids, pointing out the limitations of relevant research at the current stage and the aspects that should be strengthened in future researches.

Abstract
Traditional Chinese medicine (TCM) is a systematic medicine. It provides alternative strategies for the treatment of depression with its clinical experience, comprehensive diagnosis, and treatment theory. Chinese herbal medicine (CHM) is the major form of TCM prescription, and numerous CHMs have been demonstrated to possess remarkable antidepressant-like properties. A diversity of mechanisms have been implicated in CHM-associated antidepressant property. This paper reviewed the neuroplastic mechanisms underlying the antidepressant actions of CHM, finding that CHM repairs neuroplasticity by improving neurogenesis, neurotrophic factors, synaptic spine morphology, cell signaling, glutamatergic system, monoamine neurotransmitters, and neural apoptosis. CHM thereby exerts an antidepressant effect, attempting to offer a better understanding of the mechanisms implicated in TCM-related antidepressant-like efficacy and laying a foundation for the scientific evaluation and development of TCM in treating depression.

Abstract
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a frustrating and often debilitating disease. Current studies have shown that Traditional Chinese Medicine (TCM) can improve patients' quality of life and alleviate CP/CPPS symptoms. In this study, the efficacy of Hedyotis diffusa Willd aqueous extraction in experimental autoimmune prostatitis (EAP) mice models was revealed. The C57BL/6 mice were randomly assigned to three groups. Except for the control group, all other groups were subcutaneously injected with 0.2 ml emulsion of T2 peptide, on day 0 and day 14, for inducing EAP models. After the EAP modelling, oral saline was given to the model group, while the H. diffusa group was treated with aqueous extract of H. diffusa Willd. Micturition habits and withdrawal response frequencies were measured. Haematoxylin and eosin staining and immunohistochemistry were used to investigate inflammatory cell infiltration and TNF-α in the prostate tissue respectively. TNF-α levels in the serum were evaluated by ELISA. The H. diffusa Willd aqueous extraction considerably reduced the urine spots number and increased the pain threshold in H. diffusa group. H. diffusa group showed significantly reduced inflammatory lesion and inflammatory cell infiltration than the model group. The levels of TNF-α in H. diffusa group were considerably reduced.

Abstract
Coronavirus disease-2019 (COVID-19) is a respiratory tract infection, accompanied with severe or fatal pneumonia like symptoms and sometime death. It has posed to be an ongoing global health emergency caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Due to a sudden outbreak and a large number of infections and deaths, it became a major concern all over the world. The options available as effective therapeutic, should be urgently exercised to handle this pandemic disease. So far, no specific and accurate anti-SARS-CoV-2 treatment is recommended because of the absence of sufficient clinical evidence. In such cases, the clinical use of available drugs is always considered to be on top priority. A broad-spectrum antiviral agent, Remdesivir is found effective in many cases and recommended by many clinicians in many countries. This drug acts as a potential inhibitor of viral RNA-dependent RNA polymerase protein, and thus likely to be efficacious in SARS-CoV-2 infection. Tocilizumab is currently recommended by many hospitals as an alternative treatment for critically ill COVID-19 patients. The tocilizumab has been administered to control cytokine storms that occurred due to the release of proinflammatory cytokine including interleukin 6. Chloroquine and hydroxychloroquine were also used in hospitals, to handle severe COVID-19 patients. Currently, plasma therapy has been exercised as a therapeutic alternative, especially to handle severe COVID-19 patients. In addition, herbal medicines are expected to play significant role in the control and prevention of COVID-19. All these therapeutic options have their advantages and limitations. This review highlights the therapeutic potential of these available drugs, along with their mechanism of action and shortcomings. We have provided detailed information on available therapeutic options, which have proved to be effectual in improving clinical symptoms of severe COVID-19 patients.

Abstract
Chinese Herbal Medicines (CHM) are the most common interventions of traditional Chinese medicine (TCM), typically administered as either single herbs or formulas. Systematic reviews (SRs) are essential references for evaluating the efficacy and safety of CHM treatments accurately and reliably. Unfortunately, the reporting quality of SRs with CHM is not optimal, especially the reporting of CHM interventions and the rationale of why these interventions were selected. To address this problem, a group of TCM clinical experts, methodologists, epidemiologists, and editors has developed a PRISMA extension for CHM interventions (PRISMA-CHM) through a comprehensive process, including registration, literature review, consensus meeting, three-round Delphi survey, and finalization. The PRISMA checklist was extended by introducing the concept of TCM Pattern and the characteristics of CHM interventions. A total of twenty-four items (including sub-items) are included in the checklist, relating to title (1), structured summary (2), rationale (3), objectives (4), eligibility criteria (6), data items (11), synthesis of results (14, 21), additional analyses (16, 23), study characteristics (18), summary of evidence (24), and conclusions (26). Illustrative examples and explanations are also provided. The group hopes that PRISMA-CHM 2020 will improve the reporting quality of SRs of CHM.

Abstract
Clinical studies have shown that renal injury in Corona Virus Disease 2019 (COVID-19) patients has been a real concern, which is associated with high mortality and an inflammation/apoptosis-related causality. Effective target therapy for renal injury has yet been developed. Besides, potential anti-COVID-19 medicines have also been reported to cause adverse side effects to kidney. Chinese Herbal Medicine (CHM), however, has rich experience in treating renal injury and has successfully applied in China in the battle of COVID-19. Nevertheless, the molecular mechanisms of CHM treatment are still unclear. In this study, we searched prescriptions in the treatment of renal injury extensively and the potential mechanisms to treat COVID-19 related renal injury were investigated. The association rules analysis showed that the core herbs includes Huang Qi, Fu Ling, Bai Zhu, Di Huang, Shan Yao. TCM herbs regulate core pathways, such as AGE-RAGE, PI3K-AKT, TNF and apoptosis pathway, etc. The ingredients (quercetin, formononetin, kaempferol, etc.,) from core herbs could modulate targets (PTGS2 (COX2), PTGS1 (COX1), IL6, CASP3, NOS2, and TNF, etc.), and thereby prevent the pharmacological and non-pharmacological renal injury comparable to that from COVID-19 infection. This study provides therapeutic potentials of CHM to combat COVID-19 related renal injury to reduce complications and mortality.

Abstract
Xin Su Ning (XSN) is a China patented and certified herbal medicine used to treat premature ventricular contractions (PVCs) since 2005. A recent completed clinical trial of 861 patients showed that XSN had similar PVC inhibition rate to the class I antiarrhythmic drug mexiletine, at 65.85% for XSN and 63.10% for mexiletine. We have previously reported that XSN prolongs action potential duration (APD) and suppresses action potential amplitude (APA) of the cardiac ventricular myocytes. In this report we aim to reveal the effect of XSN on the ionic channels that govern APD and APA, which would help to explain the cellular electrophysiological mechanism of XSN. Our main findings are: (1) On ECG recorded in isolated rat, in the presence of XSN the amplitude of R wave was significantly decreased and the amplitude of T wave was increased significantly; (2) XSN blocked hNaV1.5 channel stably transfected cell line in a dose-dependent manner with an IC50 of 0.18 ± 0.02 g/L; and (3) XSN suppresses hERG channels in a dose-dependent manner with an IC50 of 0.34 ± 0.01 g/L. In conclusion, the clinical antiarrhythmic efficacy of XSN is based on its class I and Class III antiarrhythmic properties by suppression hNaV1.5 channel and hERG channels, which are directly responsible for XSN’s effect on APA suppression and APD prolongation.

Abstract
Nine autosomal dominant spinocerebellar ataxias (SCAs) are caused by an abnormal expansion of CAG trinucleotide repeats that encodes a polyglutamine (polyQ) tract within different genes. Accumulation of aggregated mutant proteins is a common feature of polyQ diseases, leading to progressive neuronal dysfunction and degeneration. SCA type 3 (SCA3), the most common form of SCA worldwide, is characterized by a CAG triplet expansion in chromosome 14q32.1 ATXN3 gene. As accumulation of the mutated polyQ protein is a possible initial event in the pathogenic cascade, clearance of aggregated protein by ubiquitin proteasome system (UPS) has been proposed to inhibit downstream detrimental events and suppress neuronal cell death. In this study, Chinese herbal medicine (CHM) extracts were studied for their proteasome-activating, polyQ aggregation-inhibitory and neuroprotective effects in GFPu and ATXN3/Q 75 -GFP 293/SH-SY5Y cells. Among the 14 tested extracts, 8 displayed increased proteasome activity, which was confirmed by 20S proteasome activity assay and analysis of ubiquitinated and fused GFP proteins in GFPu cells. All the eight extracts displayed good aggregation-inhibitory potential when tested in ATXN3/Q 75 -GFP 293 cells. Among them, neuroprotective effects of five selected extracts were shown by analyses of polyQ aggregation, neurite outgrowth, caspase 3 and proteasome activities, and ATXN3-GFP, ubiquitin, BCL2 and BAX protein levels in neuronal differentiated ATXN3/Q 75 -GFP SH-SY5Y cells. Finally, enhanced proteasome function, anti-oxidative activity and neuroprotection of catalpol, puerarin and daidzein (active constituents of Rehmannia glutinosa and Pueraria lobata) were demonstrated in GFPu and/or ATXN3/Q 75 -GFP 293/SH-SY5Y cells. This study may have therapeutic implication in polyQ-mediated disorders.

Abstract
Although the efficacy and the health care advantages of Chinese herbal medicine (CHM) have become increasingly recognized worldwide, the potential side effects and toxicity still restrict its broader application. This study established and applied an integrated platform anchored on automatic patch clamp system to screen and evaluate a collection of CHM extracts, compositions and monomeric compounds for in vitro cardiac toxicity. Of 1036 CHM samples screened, 2.79% significantly inhibited hERG channel activity. Among them, Strychnine was identified for the first time as a potent hERG inhibitor with an IC 50 of 6.65±1.04μ M in comparison to that of Dofetilide at 1.80±0.24μ M and Quinidine at 7.42±0.54μ M. Langendorff-perfusion experiments confirmed that strychnine increased QT interphase from 71.69±5.34 ms to 98.61±5.54 ms and decreased heart rates from 227.65±5.40 bmp to 162.91±14.70 bmp in isolated rat hearts. The cardiac toxicity effect of strychnine appears to be specific to hERG channel since an in vitro multiplex imaging analysis showed that it did not affect cellular phenotypes such as cell vitality, nucleus area, mitochondria mass and function, nor intracellular calcium in rat primary myocytes. This integrated high-throughput hERG patch clamp and high-content multi-parameter imaging cardiac toxicity screen approach should be useful for large-scale preclinical evaluation of complex Chinese herbal medicine.

Utilization of Chinese herbal medicine and its association with the risk of fracture in patients with Parkinson's disease in Taiwan. JOURNAL OF ETHNOPHARMACOLOGY 2018; 226:168-175. [PMID: 30118835 DOI: 10.1016/j.jep.2018.08.021] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/15/2018] [Revised: 08/12/2018] [Accepted: 08/13/2018] [Indexed: 06/08/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional Chinese medicine (TCM) has been used for over two thousand years to treat motor impairments corresponding to the clinical manifestations of Parkinson's disease (PD). AIM OF THE STUDY This study aimed to investigate the prescription of Chinese herbal medicine (CHM) for the management of PD and further determine whether CHM can improve motor function and decrease the risk of incident fracture. MATERIALS AND METHODS Patients older than 40 years newly diagnosed with PD between January 1997 and December 2010 were selected from the National Health Insurance Research Database (NHIRD) and followed up until the end of 2013. We used 1:1 frequency matching by age, sex, index year, and initial diagnostic year to compare the TCM users and non-TCM users. We used a Cox regression model and the Kaplan-Meier method to estimate the risk of developing fracture among the TCM and non-TCM users. RESULTS In total, 7197 patients older than 40 years were newly diagnosed with PD between 1997 and 2010 in Taiwan. Among these patients, 3456 were TCM users, and 3730 were non-TCM users. We compared 2007 PD patients with comparable demographic characteristics and comorbidity profiles between the two cohorts. During the follow-up period, compared with the non-TCM cohort, fewer patients in the TCM cohort had incident fractures (adjusted hazard ratio: 0.5, 95% CI: 0.44-0.56). The cumulative incidence of fracture was lower in the TCM cohort (log-rank test, p < 0.0001). Shi-Chang-Pu (Acorus gramineus Aiton), Yuan-Zhi (Polygala tenuifolia Willd), Bei-Mu (Fritillaria cirrhosa D. Don), Hai-Piao-Xiao (Sepiella maindronide Rochebrune; Sepia esculenta Hoyle), and Tian-Ma (Gastrodia elata Blume) constituted the core Chinese herbal medicine prescriptions used to treat PD patients. CONCLUSIONS The present study identified the core prescription pattern for the management of PD in Taiwan. Complementary CHM therapy was associated with a reduced risk of fracture in PD patients.

Abstract
Chinese herbal medicine (CHM) has been widely used in the treatment of advanced non-small-cell lung cancer (NSCLC), but their efficacy and safety remain controversial. We sought to comprehensively aggregate and evaluate the available evidence on the efficacy and safety of the combination treatment with CHM and epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) in NSCLC patients. Our exhausted and systematical searching strategy yielded 64 related randomized controlled trials involving 4384 patients. Compared with EGFR-TKIs therapy alone, meta-analysis showed significant differences favoring the combination treatment in progression-free survival ([Formula: see text]), median survival time ([Formula: see text]), one-year survival rate ([Formula: see text]), two-year survival rate ([Formula: see text]), probability of severe toxicities ([Formula: see text]), objective response rate ([Formula: see text]), Karnofsky performance status ([Formula: see text]), and improvement in percentage of CD3[Formula: see text] T lymphocyte ([Formula: see text]) and CD4[Formula: see text] T lymphocyte ([Formula: see text]). Though these results require further confirmation, they are prone to show a potential therapeutic value of CHM in improving the clinical effect, overcoming the drug resistance and toxicities as an adjunctive therapy to EGFR-TKIs.

Abstract
MaZiRenWan (MZRW, also known as Hemp Seed Pill) is a Chinese Herbal Medicine which has been demonstrated to safely and effectively alleviate functional constipation (FC) in a randomized, placebo-controlled clinical study with 120 subjects. However, the underlying pharmacological actions of MZRW for FC, are still largely unknown. We systematically analyzed the bioactive compounds of MZRW and mechanism-of-action biological targets through a novel approach called “focused network pharmacology.” Among the 97 compounds identified by UPLC-QTOF-MS/MS in MZRW extract, 34 were found in rat plasma, while 10 were found in rat feces. Hierarchical clustering analysis suggest that these compounds can be classified into component groups, in which compounds are highly similar to each other and most of them are from the same herb. Emodin, amygdalin, albiflorin, honokiol, and naringin were selected as representative compounds of corresponding component groups. All of them were shown to induce spontaneous contractions of rat colonic smooth muscle in vitro. Network analysis revealed that biological targets in acetylcholine-, estrogen-, prostaglandin-, cannabinoid-, and purine signaling pathways are able to explain the prokinetic effects of representative compounds and corresponding component groups. In conclusion, MZRW active components enhance colonic motility, possibly by acting on multiple targets and pathways.

Abstract
Autophagy is an evolutionarily conserved degradation process which eliminates dysfunctional proteins and cytoplasmic components to maintain homeostasis for cell survival. Increasing evidence has demonstrated the modulatory role of autophagy in ischemic heart diseases (IHDs). Traditionally, this process has been recognized as having protective functions, such as inhibiting atherosclerosis progression and reducing cell death during the ischemic phase. However, recent studies have suggested its dual roles in myocardial ischemia/reperfusion (MIR) injury. Excessive autophagy may play a deleterious role in cardiac function, due to overwhelming clearance of cellular constituents and proteins. Hence modulation of autophagy to increase cardiomyocyte survival and improve cardiac function is meaningful for the treatment of IHD. Chinese herbal medicine, including extractive compounds and patented drugs, has shown its potential role in treating IHD by addressing autophagy-related mechanisms. This review summarizes the updated knowledge on the molecular basis and modulatory role of autophagy in IHD and the recent progress of Chinese herbal medicine in its treatment.

Abstract
Stroke is one of the major causes of death and adult disability worldwide. The underlying pathophysiology of stroke is highly complicated, consisting of impairments of multiple signalling pathways, and numerous pathological processes such as acidosis, glutamate excitotoxicity, calcium overload, cerebral inflammation and reactive oxygen species (ROS) generation. The current treatment for ischemic stroke is limited to thromolytics such as recombinant tissue plasminogen activator (tPA). tPA has a very narrow therapeutic window, making it suitable to only a minority of stroke patients. Hence, there is great urgency to develop new therapies that can protect brain tissue from ischemic damage. Recent studies have shown that new vessel formation after stroke not only replenishes blood flow to the ischemic area of the brain, but also promotes neurogenesis and improves neurological functions in both animal models and patients. Therefore, drugs that can promote angiogenesis after ischemic stroke can provide therapeutic benefits in stroke management. In this regard, Chinese herbal medicine (CHM) has a long history in treating stroke and the associated diseases. A number of studies have demonstrated the pro-angiogenic effects of various Chinese herbs and herbal formulations in both in vitro and in vivo settings. In this article, we present a comprehensive review of the current knowledge on angiogenesis in the context of ischemic stroke and discuss the potential use of CHM in stroke management through modulation of angiogenesis.

Are meta-analyses of Chinese herbal medicine trials trustworthy and clinically applicable? A cross-sectional study. JOURNAL OF ETHNOPHARMACOLOGY 2015; 162:47-54. [PMID: 25554640 DOI: 10.1016/j.jep.2014.12.028] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/31/2014] [Revised: 12/18/2014] [Accepted: 12/18/2014] [Indexed: 06/04/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Meta-analysis (MA) on Chinese herbal medicine (CHM) trials is increasingly published and indexed in major international databases but their trustworthiness and clinical applicability is uncertain. We aimed to assess the characteristics and methodological quality of MA on CHM. MATERIALS AND METHODS Cross-sectional study. MA published during 1993-2013 was sampled from MEDLINE, EMBASE, Cochrane Database of Systematic Reviews and Database of Abstracts of Reviews of Effect. Bibliographical characteristics were abstracted and methodological quality was assessed using the validated AMSTAR tool by two independent reviewers. RESULTS Total of 201 MA were included and half were published in or after 2009. Only 7.5% being updates of previous reviews. Majority are published in journals with low or no impact factor, with a median of 1.5. These MA demonstrated methodological strengths in ensuring comprehensive literature search, providing characteristics of the included studies, assessing the scientific quality of included studies and appropriately using the scientific quality of included studies in formulating conclusions. Nevertheless, weaknesses in protocol provision, listing of included and excluded studies, inclusion of grey literature, use of appropriate meta-analytic technique as well as reporting of funding sources were prevalent. CHM and control interventions pooled in majority of MA are found to have substantial clinical heterogeneity in terms of composition, dosage form and route of administration. CONCLUSIONS There are rooms for improvement in methodological rigor, and in choosing clinically homogenous interventions and control for statistical pooling. These shortcomings limit the trustworthiness and clinical applicability of existing MA on CHM trials. To overcome the limitations of pair-wise meta-analysis in synthesizing trials comparing different CHM and control interventions, the potential of network meta-analysis should be explored.

Effects of sheng hua tang on uterine involution and ovarian activity in postpartum dairy cows. ASIAN-AUSTRALASIAN JOURNAL OF ANIMAL SCIENCES 2014; 26:1247-54. [PMID: 25049906 PMCID: PMC4093405 DOI: 10.5713/ajas.2013.13042] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/15/2013] [Revised: 05/16/2013] [Accepted: 04/08/2013] [Indexed: 11/27/2022]
Abstract
The effects of Sheng Hua Tang (SHT) on uterine involution and ovarian activity were investigated in postpartum dairy cows. SHT (70 g) was given to dairy cows (n = 10) to evaluate its effects for five days from the first postpartum day. Postpartum cows fed with a basal diet without SHT were used as the control group (n = 10). Ultrasounds and blood tests were recorded for four weeks from postpartum day seven with a 3-d interval. The results showed that the areas and diameters of endometria were significantly (p<0.01) reduced in the group that received SHT compared to the control group on the seventh postpartum day. The group that received SHT had an intrauterine fluid volume mean of 1.2±0.6 cm(3), which was significantly lower than that of the control group, 2.3±0.8 cm(3) (p<0.01) on the 13th postpartum day. In addition, the uterine tension score was a mean of 1.0±0.0 in the group that received SHT, which was also significantly lower than that of the control group, 1.5±0.5 (p<0.01) on the 19th postpartum day. Taken together, the Chinese herbal medicine remedy, SHT, promoted uterine involution and ovarian activity in postpartum dairy cows.
