ABSTRACT

Urolithiasis is a common and complex disease of the urinary system, which can cause urinary tract blockage, urinary tract infection, and even damage to urinary system-related tissues. Although urolithiasis can be cured, its high recurrence rate and the development of chronic kidney disease in some patients have drawn the attention of nephrologists. Although the application of extracorporeal lithotripsy, percutaneous nephrolithotomy and other minimally invasive techniques have made the treatment of urolithiasis more efficient, pharmacotherapy plays an indispensable role in reducing their morbidity and recurrence rates. Traditional Chinese medicine (TCM) has been used for treatment and prevention of urolithiasis in developing countries for centuries, known for its unquestionable efficacy and safety. This article reviews the progress of clinical trials and pharmacological studies on the treatment of urolithiasis with Chinese herbal medicines (CHMs). The mechanism of CHMs in the treatment of urolithiasis mainly involve preventing further growth and aggregation of urolithiasis, reducing the PH of urine, promoting calculus dissolution. Furthermore, some CHMs can increase urine output, relax smooth muscles, and promote the removal of calculus. These findings provide new treatment strategies and options for urolithiasis and secondary kidney damage.

ABSTRACT

Prostate cancer remains the second most common malignancy in men worldwide, is a global health issue, and poses a huge health burden. Precision medicine provides more treatment options for prostate cancer patients, but its popularity, drug resistance, and adverse reactions still need to be focused on. Chinese herbal medicines (CHMs) have been widely accepted as an alternative therapy for cancer, with the advantages of multiple targets, multiple pathways, and low toxicity. We searched the experimental research and clinical practice of CHMs for prostate cancer treatment published in PubMed, Embase, and Web of Science in the last five years. We found five CHM formulas and six single CHM extracts as well as 12 CHM-derived compounds, which showed induction of apoptosis, autophagy, and cell cycle arrest, suppression of angiogenesis, proliferation, and migration of prostate cancer cells, reversal of drug resistance, and enhancement of anti-tumor immunity. The mechanisms of action include the PI3K/Akt/mTOR, AR, EGFR and Wnt/β-catenin signaling pathways, which are commonly implicated in the development of prostate cancer. We also summarized the advantages of CHMs in patients with hormone-sensitive and castration-resistant prostate cancer and provided ideas for their further experimental design and application.

ABSTRACT

Based on the data of 56 kinds of diseases and drug use in 100 kinds of cultivated Chinese herbal medicines, this paper used frequency analysis method to count the types of diseases and their drug use characteristics, and systematically analyzed the status of drug registration and monitoring standards for disease prevention and control of Chinese herbal medicines. The results showed that 14 diseases such as root rot, powdery mildew, and drooping disease were common in the production of Chinese herbal medicines. Among the 99 pesticides reported, 67.68% were chemically synthesized, 23.23% were biological pesticides, and 9.09% were mineral pesticides. Among the reported pesticides, 92.93% of them were low toxic, with relative safety. However, 70% of the production drugs were not registered in Chinese herbal medicines, and the phenomenon of overdose was serious. The current pesticide residue monitoring standards does not match well with production drugs in China. Although the matching degree between Maximum Residue Limit of Pesticide in Food Safety National Standard(GB 2763-2021) and production drugs is more than 50%, there are few varieties of Chinese herbal medicines covered. The matching degree between Chinese Pharmacopoeia(2020 edition), Green Industry Standard of Medicinal Plants and Preparations(WM/T2-2004), and production drugs is only 1.28%. It is suggested to speed up the research and registration of Chinese herbal medicine production and further improve the pesticide residue limit standard combined with the actual production, so as to promote the high-quality development of Chinese herbal medicine industry.

ABSTRACT

Ulcerative colitis (UC) is one of types of inflammatory bowel disease with high recurrence. Recent studies have highlighted that microbial dysbiosis as well as abnormal gut immunity are crucial factors that initiate a series of inflammatory responses in the UC. Modulating the gut microbiota-intestinal immunity loop has been suggested as one of key strategies for relieving UC. Many Chinese herbal medicines including some of single herb, herbal formulas and the derived constituents have been reported with protective effect against UC through modulating gut microbiome and intestinal immunity. Some clinical trials have shown promising results. This review thus focused on the current knowledge on using Chinese herbal medicines for treating UC from the mechanism aspects of regulating intestinal homeostasis involving microbiota and gut immunity. The existing clinical trials are also summarized.

ABSTRACT

Diabetic neuropathic pain (DNP) is one of the common complications of diabetic peripheral neuropathy, which is difficult to be cured. The clinical manifestations of DNP include reduced pain threshold, neuropathic pain in extremities, and abnormal pain. Studies have demonstrated that nuclear factor-kappa B (NF-κB), mitogen-activated protein kinase (MAPK), Toll-like receptor 4 (TLR4), nuclear factor erythroid 2-related factor 2 (Nrf2), and phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathways are involved in the treatment of DNP by inhibiting the activation and release of inflammatory cytokines [e.g., tumor necrosis factor-alpha (TNF-α) and interleukin (IL)], regulating inflammation-mediating factors [e.g., reactive oxygen (ROS), inducible nitric oxide synthase (iNOS), cyclooxygenase (COX-2), and NF-κB inhibitor (IκB)], suppressing neurogenic inflammation, destroying the persistent damage of peripheral nerves, and repairing damaged peripheral nerves. The literature of modern medical research has demonstrated that the treatment of DNP with Chinese herbal medicines is associated with the signaling pathways above. They can treat DNP by regulating the expression of key proteins in the signaling pathways to control neurogenic inflammation and repair diabetic peripheral neuropathic damage. By summarizing the available studies, this review aims to provide a reference for the in-depth research on Chinese herbal medicines in the treatment of DNP and give new insights into the protection of diabetic peripheral nerves and the treatment of DNP with Chinese herbal medicines.

ABSTRACT

Atopic dermatitis is a chronic, refractory and inflammatory skin disease with the clinical manifestations of severe pruritus and recurrent attacks. It has a high incidence and is closely correlated with other allergic, autoimmune or infectious diseases, which can cause a variety of secondary diseases and mental and psychological disorders, seriously affecting the life quality of patients. Chinese herbal medicines have been used for the prevention and treatment of atopic dermatitis for thousands of years, and many Chinese herbal medicines (including compound prescriptions) effective for this disease have been recorded. These medicines generally have little adverse reactions and the treated patients have low recurrence rate of atopic dermatitis. According to the evidence of modern medicine, the onset of atopic dermatitis is related to the impairment of skin barrier function, abnormal immune response, and abnormal differentiation of mast cells, antigen-presenting cells, and eosinophils. Additionally, it is associated with mental, endocrine, metabolic and other factors. The defect of skin barrier function and the dysfunction of immune system are the main pathogenesis of atopic dermatitis. In recent years, scientists have achieved certain progress in improving skin barrier function with Chinese herbal medicines. This paper systematically summarizes the studies about the application of Chinese herbal medicines in regulating the expression of epidermal proteins, epidermal lipids, aquaporins, tight junction proteins, and antimicrobial peptides in recent 10 years, aiming to clarify the pathological mechanism and provide reference for the clinical research and application of Chinese herbal medicines in the treatment of atopic dermatitis.

ABSTRACT

Bladder cancer is the most prevalent malignant tumor in the urinary tract in China. Western medical treatments, including long-term regular endoscopy, intravesical chemotherapy, immunotherapy, and radical cystectomy, are effective, whereas the high recurrence rate still plagues both doctors and patients. Among the classical signaling pathways involved in the formation and progression of bladder cancer, the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway is a key one. Modern pharmacological studies have demonstrated that Chinese herbal medicines and their monomer components can alleviate the discomfort, prolong the survival, and improve the quality of life of the patients undergoing tumor treatment. The relevant literature in the past decade has revealed that flavonoids, terpenoids, polysaccharides, gambogic acids, bibenzyls, and alkaloids from Chinese herbal medicines regulate the PI3K/Akt signaling pathway to play a role in the proliferation, apoptosis, invasion, migration, drug resistance, and autophagy of bladder cancer cells, thereby exerting the activity against bladder cancer. Although some targets and the potential mechanisms of the monomer components in the treatment of bladder cancer have been clarified, the research on the monomer components is limited to in vitro cellular experiments and animal experiments. Researchers face the great challenge in the application of the monomer components from Chinese herbal medicines into clinical practice. We summarized the recent studies about the regulatory effects of monomer components from Chinese herbal medicines on the PI3K/Akt signaling pathway in bladder cancer, aiming to give insights into the research on the drug therapy of bladder cancer and the underlying mechanism.

ABSTRACT

Ovarian cancer is a malignant tumor of female reproductive system with high morbidity and mortality. Currently, ovarian cancer patients are mainly treated by primary debulking surgery combined with taxotere/cyclophosphamide (TC) chemotherapy, with the five-year survival rate of 36%-46%. Chinese medicinal materials play a positive role in preventing the occurrence and development of ovarian cancer via multiple targets. The flavonoid monomers in representative Chinese herbal medicines, such as Epimedii Folium, Scutellariae Radix, Curcumae Longae Rhizoma, Ginkgo Folium, Bupleuri Radix, and Longicerae Japonicae Flos, have been proved to have significant anti-tumor activity and been widely used in the treatment of malignant tumors. We reviewed the relevant literature and summarized that flavonoid monomers can regulate multiple signaling pathways to inhibit cell proliferation, block tumor cell cycle, induce apoptosis and autophagy, reduce the ability of cell invasion and migration, inhibit tumor angiogenesis, and reverse platinum resistance, thereby inhibiting the occurrence and development of ovarian cancer. Such pathways include phosphatidylinositol 3- kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signaling pathway, Janus kinase (JAK)/signal transducer and activator of transcription 3 (STAT3) signaling pathway, mitogen-activated protein kinase (MAPK) signaling pathway, secreted glycoprotein (Wnt)/β-catenin signaling pathway, Notch signaling pathway, and nuclear factor kappaB (NF-κB) signaling pathway. By reviewing the regulatory effect of flavonoid monomers on the signaling pathways of ovarian cancer, we aim to provide a theoretical basis for the research on the roles of flavonoid monomers in inhibiting the occurrence and development of ovarian cancer.

ABSTRACT

As a unique medical resource in China, Chinese herbal medicine plays a key role in the prevention and treatment of human diseases. With the gradual expansion of applications, the quality of Chinese herbal medicine has become the focus of attention. The quality of Chinese herbal medicines depends largely on their source authenticity. Tracing the origin of Chinese herbal medicines plays an important role in ensuring their quality and efficacy and reducing the mixing and adulteration of Chinese herbal medicines from different regions. Stable isotope technology, as a key technology for origin tracing of agricultural products and food, has been used in the research of Chinese herbal medicines from multiple sources and origins in recent years. This new technological means contributes to standardizing the origin of Chinese herbal medicines and controlling their quality from the source. Apart from introducing the basic principles of stable isotope technology and the characteristics of common stable isotopes, this study reviewed the application status of light and heavy stable isotopes in the origin tracing of Chinese herbal medicines and their correlation with ecological factors, and forecasted the application prospect of this technology in the authentication of Chinese herbal medicines, aiming to provide reference for the geographical origin tracing of Chinese herbal medicines and promote the sustainable development of traditional Chinese medicine.

ABSTRACT

Chinese herbal medicines (CHMs) are one of the important bioresources of medicine, which works by unlocking nature's ability to prevent diseases and recover from illnesses. Recently, it has ascended to the world stage and become a global icon. Nowadays, a considerable of researches have focused on the quality evaluation of CHMs. However, it is difficult to meet the reasonable needs of human beings for safe drug use to evaluate the quality of a huge number of inferior goods for the CHMs contaminated by pesticides and heavy metals. Hence to explore an eligible medicinal plant cultivation pattern, which can provide high quality CHMs sustainably, is most promising. This review analyzed the situation and characteristics of medicinal plant resources in different periods, including wild-harvested and cultivated resources during different stages, putting forward that ecological cultivation must be the way to develop medicinal plant cultivation and to obtain high quality CHMs.

ABSTRACT

Chinese traditional medicine has provided, since ancient times, a basis for health care and medicine to the Chinese nation and for China's national stability. Identification of the constituents responsible for therapeutic and undesired effects of Chinese herbal medicines is a type of key research facilitating the modernization of these medicines. For a complex Chinese herbal medicine, multi-compound pharmacokinetic research is a useful approach to identifying its constituents that are bioavailable (in their unchanged and/or metabolized forms) at loci responsible for the medicine's therapeutic action and to characterizing the compounds' disposition and pharmacokinetics related to the action. In addition, such pharmacokinetic research is also useful for identifying herbal compounds associated with the medicine's adverse effects and drug-drug interaction potential. Over the past decade, great advances have been achieved in the theory, methodology, associated techniques, and their application of such multi-compound pharmacokinetic research, which has become an emerging field in pharmacokinetics. In this perspective, we elaborate on the methodology, technical requirements, and key analytical techniques of multi-compound pharmacokinetic research on Chinese herbal medicines, describe research examples regarding investigation of pharmacokinetics and disposition of a class of bioactive herbal constituents (ginsenosides of Panax notoginseng root) and pharmacokinetics-based identification of potential therapeutic compounds from a dosed Chinese herbal medicine (LianhuaQingwen capsule), and discuss follow-up development for the multi-compound pharmacokinetic research.

ABSTRACT

Lung diseases and their related complications represent a critical source of morbidity and mortality globally and have become a research focus in recent years. There are plenty of hazards that threaten the health of lung by exposure to external environmental stimuli, such as dust, cigarette smoke, PM2.5, air pollution and pathogen infection. These risks lead to the impairment of lung function and subsequent lung diseases including pneumonia, chronic obstructive pulmonary disease (COPD), asthma and idiopathic pulmonary fibrosis (IPF). Compared with antibiotics and corticosteroids therapies, traditional Chinese medicine prescriptions are more effective with fewer side effects. A considerable variety of bioactive ingredients have been extracted and identified from Chinese herbal medicines and are used for the treatment of different lung diseases, including resveratrol. Increasing studies have reported promising therapeutic effects of resveratrol against lung diseases by inhibiting oxidative stress, inflammation, aging, fibrosis and cancer both in vitro and in vivo. In this review, the recent progress in the studies of lung-protective effects and underlying mechanisms of resveratrol and also highlight the potency of resveratrol and traditional Chinese prescriptions containing resveratrol as promising therapeutic options were summarized for the treatment of lung and respiratory diseases.

ABSTRACT

The progression of renal damage in diabetic nephropathy(DN)is closely related to Nod-like receptor protein3(NLRP3)inflammasome activation. The characteristics of NLRP3 inflammasome activation include the changed expression and combination levels of NLRP3, apoptosis-associated speck-like protein(ASC)and pro-caspase-1, the increased expression levels of caspase-1, interleukin(IL)-1β and IL-18 and the excessive release levels of the relative inflammatory mediators. Its molecular regulative mechanisms involve the activation of multiple signaling pathways including reactive oxygen species(ROS)/thioredoxin-interacting protein(TXNIP)pathway, nuclear factor(NF)-κB pathway, nuclear factor erythroid-related factor 2(Nrf2)pathway, long non-coding RNA(lncRNA)pathway and mitogen-activated protein kinases(MAPKs)pathway. In addition, more importantly, never in mitosis aspergillus-related kinase 7(Nek7), as a kinase regulator, could target-combine with NLRP3 at upstream to activate NLRP3 inflammasome. Some extracts of Chinese herbal medicines(CHMs)such as quercetin, curcumin, cepharanthine, piperine and salidroside, as well as Chinese herbal compound prescriptions such as Wumei Pills both could treat NLRP3 inflammasome to ameliorate inflammatory renal damage in DN. Therefore, accurately clarifying the targets of anti-inflammatory CHMs and Chinese herbal compound prescriptions delaying DN progression by targeting the molecular regulative mechanisms of NLRP3 inflammasome activation will be one of the development directions in the future.

ABSTRACT

@#Introduction: Consumption of Chinese Herbal Medicine (CHMs) have escalated globally. They are preferred treatment for minor diseases or disorders. In Malaysia, CHMs are common home remedies during pregnancy and postpartum. Angelica sinensis (Danggui) is a staple CHMs during postpartum for purpose of nourishing blood and resolving stasis. Concerns are raised over possible heavy metals toxicity. Objective: This study aims to (i) determine Danggui consumption among postpartum mothers, (ii) quantify its heavy metals level, namely Lead (Pb), Cadmium (Cd), Arsenic (As) and Chromium (Cr) and (iii) determine health risks of Danggui consumption among mothers. Methods: A cross-sectional study involving 112 postpartum mothers was carried out in Kuala Lumpur. Danggui samples were collected from nine districts in Kuala Lumpur (Segambut, Seputeh, Cheras, Kepong, Bandar Tun Razak, Titiwangsa, Setiawangsa, Batu and Lembah Pantai). Heavy metals were extracted using microwave digester and analysed using Inductively coupled plasma mass spectrometry (ICPMS). Hazard Quotient (HQ) was used to determine non-carcinogenic health risks for herbal medicine consumption. Results: Danggui was consumed by 19.6% of mothers (n=22). Among them, incidence of jaundice was 63.6% and need for phototherapy was 40.9%. Heavy metals contaminations were found in the decreasing order of Cr > As > Pb > Cd with median (interquartile) of 3996.3 (2805.6) μg/ kg, 128.3 (56.7), 98.6 (99.1) and 37.0 (35.0) respectively. No non-carcinogenic health risks were found for all four metals. Conclusion: Alarming concentrations of heavy metals were quantified in Danggui warranting for further investigation to safeguard health of postpartum mothers.

ABSTRACT

The soil fertility has great impacts on the yielding of Chinese medicinal materials, as well as the generation of major components. The practices showed that soil fertility has been decayed with the growth of cultivation years,which is leading to adverse effect on quality and quantity of Chinese medicinal materials. However, there was a lack of domestic unified standard for assessment of soil fertility of Chinese medicinal material cultivation, which has seriously limited the soil management and quality control. In this text, we reviewed the progress on research of soil fertility evaluation, built the soil fertility evaluation index including soil texture,soil bulk density,soil organic matter,soil acidity and alkalinity,soil available nitrogen,soil available phosphorus, soil available potassium,soil animals and soil microorganisms. It would provide the direction and thought for standard-settin on soil fertility evaluation of Chinese medicinal material cultivation.
