Unveiling antibiotic contamination in surface water: A study of the Huaihe River Basin's Huaibei Plain, a significant Chinese herbal medicine planting region

The abuse of antibiotics has caused the accumulation of antibiotic residues in environmental media, threatening the ecosystem and human health. Many studies on the distribution of aqueous antibiotics have been reported. However, the pollution status of antibiotics in the environment in Chinese herbal medicine planting areas is rarely comprehensively clarified, resulting in the lack of updated pollution data and conducive suggestions for ecological cultivation and sustainable development of Chinese herbal medicine. Thus, we comprehensively investigated the distribution, profiles, sources, and risks of the antibiotics in the surface water of an important tributary of the Huaihe River Basin, located in Bozhou City, a significant Chinese herbal medicine planting region. Solid-phase extraction coupled with an ultra-performance liquid chromatography-tandem mass spectrometer (SPE-UPLC-MS) was utilized to detect the antibiotics in the water. 27 kinds of antibiotics were identified with total concentrations ranging from 75.01 to 1737.99 ng·L−1, with doxycycline (DC) and doxycycline hydrochloride (DCH) possessed the highest concentration. And DC, DCH, oxilinic acid (OA), sulfamethoxazole (SMZ), clarithromycin (CLA), and roxithromycinum (ROX) were the main antibiotics detected in this basin. Correlation analysis and principal component analysis (PCA) indicated that animal husbandry was the primary source of antibiotics. Furthermore, the ecological risk assessment revealed that certain antibiotics could seriously threaten the survival of aquatic organisms, implying that local Chinese herbal medicines might be at similar growth risk. The drinking risk assessment showed that antibiotics in the water posed low risks for human, and children faced a greater drinking risk than adults. The study can help to facilitate the management of aqueous antibiotic pollution for the ecological cultivation and safe production of Chinese herbal medicine.

Appropriate crop rotation alleviates continuous cropping barriers by changing rhizosphere microorganisms in Panax notoginseng

Crop rotation is the most sustainable way to solve the CCO which is the main problem restricting the development of Chinese herbal medicine. In this study, we used Illumina high-throughput sequencing technology to study the effects of different interval years on rhizosphere microorganisms of Panax notoginseng at 1, 2 and 3 years intervals. The results showed that the number of beneficial bacteria increased while the pathogenic bacteria decreased during crop rotation. We also found that choosing the suitable crop is more effective than extending the rotation cycle duration. Phylogenetic analysis results showed that the preceding crop plays a decisive role in the rotation. Indicator, Random forest and Network all showed that crop rotation is to increase Trichoderma to combat CCOs. Our study indicated that job's tears is more suitable as the preceding crop of P. notoginseng. T. asperellum play a key role in crop rotation.

PI3K/AKT Signal Pathway: A Target of Natural Products in the Prevention and Treatment of Alzheimer's Disease and Parkinson's Disease.

Alzheimer’s disease (AD) and Parkinson’s disease (PD) are two typical neurodegenerative diseases that increased with aging. With the emergence of aging population, the health problem and economic burden caused by the two diseases also increase. Phosphatidylinositol 3-kinases/protein kinase B (PI3K/AKT) signaling pathway regulates signal transduction and biological processes such as cell proliferation, apoptosis and metabolism. According to reports, it regulates neurotoxicity and mediates the survival of neurons through different substrates such as forkhead box protein Os (FoxOs), glycogen synthase kinase-3β (GSK-3β), and caspase-9. Accumulating evidences indicate that some natural products can play a neuroprotective role by activating PI3K/AKT pathway, providing an effective resource for the discovery of potential therapeutic drugs. This article reviews the relationship between AKT signaling pathway and AD and PD, and discusses the potential natural products based on the PI3K/AKT signaling pathway to treat two diseases in recent years, hoping to provide guidance and reference for this field. Further development of Chinese herbal medicine is needed to treat these two diseases.

Research progress on anti-alcoholic gastric injury active components and mechanisms of Chinese herbal medicine

Alcohol is considered to be one of the main causes for gastric injury, and alcoholic gastric injury has been becoming one of the global health problems, which seriously affects the quality of human life. Many studies suggest that the active components extracted from Chinese herbal medicine can effectively reduce the degree of alcohol-induced gastric injury. The active components and its mechanism of anti-alcoholic gastric injury of Chinese herbal medicine reported in recent five years were preliminarily summarized according to the classification of terpenoids, flavonoids, polyphenols, polysaccharides, volatile oils, phenylpropanoids and alkaloids in this paper. The terpenoids could improve oxidative stress and inflammatory response by regulating relevant signaling pathways. The flavonoids are mainly related to antioxidant and anti-inflammatory properties. The polyphenols mainly regulate the level of relevant factors involved in inflammatory pathway, oxidative stress and apoptosis pathway. The polysaccharides could enhance the ability of gastric mucosal defense factor by inhibiting oxidative stress injury and inflammatory response. Phenylpropanoids could enhance the gastric mucosal defense factor. The volatile oils mainly inhibit H~+/K~+-ATPase activity or inflammatory reaction. Alkaloids are closely related to the inhibition of inflammatory response and the improvement of antioxidant system. This paper aims to provide reference for further research and development of Chinese herbal medicine against alcoholic gastric injury.

Chinese herbal medicine resources: Where we stand

In recent years, the development of Chinese herbal medicine (CHM) has been challenged by shortages of CHM resources and drug safety concerns related to end products. There have been significant efforts by Chinese scholars to tackle these challenges, which are revealed by analyzing the research trend of CHM resources via surveying Chinese Traditional and Herbal Drugs (Zhong Cao Yao), a representative journal in CHM. Our study focused on 781 articles in CHM resources from 2013 to 2018 and included four subject areas: germplasm resources, quality analysis and evaluation, cultivation, and bioengineering of CHM. Discussion and prospective for future investigations were also presented, including: construct the core germplasm of medicinal plants and expand germplasms; combine molecular research with field experiments and promote the deeper study of cultivation of CHM plants; improve the quality evaluation method of CHM and strengthen the identification of Chinese patented medicines; promote the sustainable development of CHM resources by utilizing bioengineering and synthetic biology. This study helps international scholars understand the status quo of CHM research and provides theoretical support for the healthy, modern, and international development of CHM, and it will facilitate the sustainable development of the traditional Chinese medicine industry.

Chinese herbal medicine for acute upper respiratory tract infections and reproductive safety: A systematic review.

Acute upper respiratory tract infections (AURTIs) are common and self-limited in people with normal immunity but sometimes lead to poor clinical outcomes under specific conditions such as pregnancy if not treated appropriately. Chinese herbal medicines (CHM), which are widely used to treat AURTIs, have proven to be effective in preclinical and clinical studies. This review focuses on the bioactivities of typical CHM and the adverse reactions they cause, and especially issues with reproductive safety when treating AURTIs. The main mechanisms for clinical efficacy may include anti-viral, anti-bacterial, anti-inflammatory, antipyretic, and immunomodulatory action as indicated by preclinical evidence. Most clinical trials indicate that CHM shortens the natural course of AURTIs and that it relieves related symptoms such as a fever, headaches, coughing, myalgia, a cold, sore throat, and a nasal obstruction. However, some CHM have a range of adverse effects and potentially affect reproduction from endocrinal secretion to embryo development while others do not. Therefore, clinical adverse reactions and preclinical studies on the toxicity of CHM are discussed. More reliable evidence is required to conclude that CHM are efficacious and safe for pregnant women with AURTIs. This review should help to promote advances in the research on and development of CHM as alternative treatments for AURTIs and offer insight into strategies to manage the safety of CHM during clinical use.

Usefulness of Chinese Herbal Medicines as Host-Directed Therapeutics against Mycobacterial Infections: A Review.

The high incidence of tuberculosis (TB) in developing countries, the resurgence of TB in industrialized countries, and the worldwide increase in the prevalence of Mycobacterium avium complex infections have prompted the quest for new antimycobacterial drugs. However, the development of such chemotherapeutics is currently making very slow progress. It therefore appears that devising improved administration protocols for clinical treatment against intractable mycobacteriosis using existing chemotherapeutics is more practical than awaiting the development of novel antimycobacterial drugs. The modulation of host immune responses using immunoadjunctive agents may increase the efficacy of antimicrobial treatment against mycobacteriosis. Particularly, the mild and long-term up-regulation of host immune reactions against mycobacterial pathogens using Chinese herbal medicines (CHMs) may be beneficial for immunoadjunctive therapy. This review focuses on the current status and future prospects regarding the development of CHMs that can be useful for the clinical control of intractable mycobacterial infections.

Though there exists a weak basic research and it is hard for promotion and regulation, the policy of good and the desire for botanical pesticides will accelerate its development, and replace traditional chemical pesticides gradually. This paper reviews the current situation of botanical pesticides, and gives some pertinence suggestions according to the existing problems and challenges. Research on botanical pesticides will become the key point to solve the problem of excessive pesticides residues and heavy metal contamination, and promote the healthy development of Chinese materia medica.

Research model on commodity specification standard of radix Chinese materia medica

As an important part of the market commodity circulation, the standard grade of Chinese traditional medicine commodity is very important to restrict the market order and guarantee the quality of the medicinal material. The State Council issuing the "protection and development of Chinese herbal medicine (2015-2020)" also make clear that the important task of improving the circulation of Chinese herbal medicine industry norms and the commodity specification standard of common traditional Chinese medicinal materials. However, as a large class of Chinese herbal medicines, the standard grade of the radix is more confused in the market circulation, and lack of a more reasonable study model in the development of the standard. Thus, this paper summarizes the research background, present situation and problems, and several key points of the commodity specification and grade standard in radix herbs. Then, the research model is introduced as an example of Pseudostellariae Radix, so as to provide technical support and reference for formulating commodity specifications and grades standard in other radix traditional Chinese medicinal materials.

Standardization of the terms for Chinese herbal functions based on functional targeting

Functional analysis concisely summarizes and concentrates on the therapeutic characteristics and features of Chinese herbal medicine. Standardization of the terms for Chinese herbal functions not only plays a key role in modern research and development of Chinese herbal medicine, but also has far-reaching clinical applications. In this paper, a new method for standardizing the terms for Chinese herbal function was proposed. Firstly, functional targets were collected. Secondly, the pathological conditions and the mode of action of every functional target were determined by analyzing the references. Thirdly, the relationships between the pathological condition and the mode of action were determined based on Chinese medicine theory and data. This three-step approach allows for standardization of the terms for Chinese herbal functions. Promoting the standardization of Chinese medicine terms will benefit the overall clinical application of Chinese herbal medicine.
