Substation of vermicompost mitigates Cd toxicity, improves rice yields and restores bacterial community in a Cd-contaminated soil in Southern China.

Cadmium (Cd) contamination in agricultural soil is a global concern for soil health and food sustainability because it can cause Cd accumulation in cereal grains. An in-situ stabilizing technology (using organic amendments) has been widely used for Cd remediation in arable lands. Therefore, the current study examined the influence of vermicompost (VC) on soil biochemical traits, bacterial community diversity and composition, Cd uptake and accumulation in rice plants and grain yield in a Cd-contaminated soil during the late growing season in 2022. Different doses of VC (i.e., V1 = 0 t ha-1, V2 = 3 t ha-1 and V3 = 6 t ha-1) and two concentrations of Cd (i.e., Cd1 = 0 and Cd2 = 50 mg Cd Kg-1 were used. We performed high-throughput sequencing of 16S ribosomal RNA gene amplicons to characterize soil bacterial communities. The addition of VC considerably affected the diversity and composition of the soil bacterial community; and increased the relative abundance of phyla Chloroflexi, Proteobacteria, Acidobacteriota, Plantomycetota, Gemmatimonadota, Patescibacteria and Firmicute. In addition, VC application, particularly High VC treatment, exhibited the highest bacterial diversity and richness (i.e., Simpson, Shannon, ACE, and Chao 1 indexes) of all treatments. Similarly, the VC application increased the soil chemical traits, including soil pH, soil organic carbon (SOC), available nitrogen (AN), total nitrogen (TN), total potassium (TK), total phosphorous (TP) and enzyme activities (i.e., acid phosphatase, catalase, urease and invertase) compared to non-VC treated soil under Cd stress. The average increase in SOC, TN, AN, TK and TP were 5.75%, 41.15%, 18.51%, 12.31%, 25.45% and 29.67%, respectively, in the High VC treatment (Pos-Cd + VC3) compared with Cd stressed soil. Redundancy analysis revealed that the leading bacterial phyla were associated with SOC, AN, TN, TP and pH, although the relative abundance of Firmicutes, Proteobacteria, Bacteroidata, and Acidobacteria on a phylum basis and Actinobacteria, Gammaproteobacteria and Myxococcia on a class basis, were highly correlated with soil environmental factors. Moreover, the VC application counteracted the adverse effects of Cd on plants and significantly reduced the Cd uptake and accumulation in rice organs, such as roots, stem + leaves and grain under Cd stress conditions. Similarly, applying VC significantly increased the fragrant rice grain yield and yield traits under Cd toxicity. The correlation analysis showed that the increased soil quantities traits were crucial in obtaining high rice grain yield. Generally, the findings of this research demonstrate that the application of VC in paddy fields could be useful for growers in Southern China by sustainably enhancing soil functionality and crop production.

Goods and Bads of the Endocannabinoid System as a Therapeutic Target: Lessons Learned after 30 Years.

The cannabis derivative marijuana is the most widely used recreational drug in the Western world and is consumed by an estimated 83 million individuals (∼3% of the world population). In recent years, there has been a marked transformation in society regarding the risk perception of cannabis, driven by its legalization and medical use in many states in the United States and worldwide. Compelling research evidence and the Food and Drug Administration cannabis-derived cannabidiol approval for severe childhood epilepsy have confirmed the large therapeutic potential of cannabidiol itself, Δ9-tetrahydrocannabinol and other plant-derived cannabinoids (phytocannabinoids). Of note, our body has a complex endocannabinoid system (ECS)-made of receptors, metabolic enzymes, and transporters-that is also regulated by phytocannabinoids. The first endocannabinoid to be discovered 30 years ago was anandamide (N-arachidonoyl-ethanolamine); since then, distinct elements of the ECS have been the target of drug design programs aimed at curing (or at least slowing down) a number of human diseases, both in the central nervous system and at the periphery. Here a critical review of our knowledge of the goods and bads of the ECS as a therapeutic target is presented to define the benefits of ECS-active phytocannabinoids and ECS-oriented synthetic drugs for human health. SIGNIFICANCE STATEMENT: The endocannabinoid system plays important roles virtually everywhere in our body and is either involved in mediating key processes of central and peripheral diseases or represents a therapeutic target for treatment. Therefore, understanding the structure, function, and pharmacology of the components of this complex system, and in particular of key receptors (like cannabinoid receptors 1 and 2) and metabolic enzymes (like fatty acid amide hydrolase and monoacylglycerol lipase), will advance our understanding of endocannabinoid signaling and activity at molecular, cellular, and system levels, providing new opportunities to treat patients.

Progress of injection sites of local infiltration analgesia in total knee arthroplasty / 中国修复重建外科杂志

OBJECTIVE@#To review the research progress of injection sites of local infiltration analgesia (LIA) in total knee arthroplasty (TKA).@*METHODS@#The relevant domestic and foreign literature in recent years was extensively reviewed. The neuroanatomy of the knee, and the research progress of the selection and the difference of effectiveness between different injection sites of LIA in clinical studies were summarized.@*RESULTS@#Large concentrations of nociceptors are present throughout the various tissues of the knee joint. Patellar tendon, subpatellar fat pad, lateral collateral ligament insertions, iliotibial band insertions, suprapatellar capsule, and posterior capsule were more sensitive to pain. Most current studies support injections into the lateral capsule, collateral ligament, retinaculum, quadriceps tendon, fat pad, and subcutaneous tissue. Whether to inject into the back of the knee and subperiosteum is controversial.@*CONCLUSION@#The relative difference of knee tissue sensitivity to pain has guiding significance for the selection of LIA injection site after TKA. Although researchers have conducted clinical trials on injection site and technique of LIA in TKA, there are certain limitations. The optimal scheme has not been determined yet, and further studies are needed.

Medication rules of traditional Chinese medicine compounds for pain / 中国中药杂志

The present study collected data on traditional Chinese medicine(TCM) compounds effective in relieving pain from the patent database of the State Intellectual Property Office(SIPO), sorted out the TCM compounds against pain in patents, and analyzed the medication rules to provide references for the research and development of new TCM drugs against pain. The data were subjected to frequency statistics, association rules, cluster analysis, and complex network analysis by IBM SPSS Modeler 18.3 and SPSS Statistical 26.0. The results showed that among the 101 oral prescriptions included in the statistics, the top 5 drugs were Glycyrrhizae Radix et Rhizoma, Angelicae Sinensis Radix, Paeoniae Radix Alba, Chuanxiong Rhizoma, and Salviae Miltiorrhizae Radix et Rhizoma, and among the 49 external prescriptions included in the statistics, the top 5 drugs were Myrrha, Olibanum, Angelicae Dahuricae Radix, Borneolum Syntheticum, and Chuanxiong Rhizoma. Whether oral or external prescriptions, the drugs were mainly warm in nature, and bitter, pungent, and sweet in flavor. According to TCM complex network analysis, the core drugs were Glycyrrhizae Radix et Rhizoma, Angelicae Sinensis Radix, Paeoniae Radix Alba, and Chuanxiong Rhizoma in oral prescriptions, and Olibanum, Myrrha, Glycyrrhizae Radix et Rhizoma, Chuanxiong Rhizoma, and Angelicae Sinensis Radix in external prescriptions. Overall, the therapeutic principles of oral prescriptions were mainly replenishing Qi, nourishing blood, and promoting Qi and blood circulation, while those of external prescriptions were activating blood, resolving stasis, promoting Qi flow, and relieving pain on the basis of the oral prescriptions. In the future research and development of TCM compounds against pain, the prescriptions should be modified with mind-tranquilizing and depression-relieving drugs. With the modernization of TCM, the development of new pain-relieving TCM compound patents based on ancient methods and clinical experience adhering to the guidance of TCM treatment based on syndrome differentiation can meet the new demand for pain treatment in the current society and give full play to the advantages of TCM in pain treatment.

Effects of isorhyncophylline on hippocampal metabolism using 1H NMR-based metabolomics combined with molecular docking analysis / 药学学报

The purpose of this study was to investigate the effect of isorhyncophylline on hippocampal endogenous metabolites in spontaneously hypertensive rats (SHR) by 1H NMR metabolomics and molecular docking. Twelve SHR were randomly divided into a model group and a treatment group. Six Wistar-Kyoto rats were selected as a control group. The rats in the treatment group were administered isorhyncophylline (0.3 mg·kg-1) while the rats in the other two groups were treated with the same amount of sterilized saline solution. Animal experiment was authorized by the Ethics Committee of Shandong University of Traditional Chinese Medicine (No. SDUTCM20210721002). Hippocampal tissues were removed after administration for 8 weeks and assayed by 1H NMR based metabolomics technology combined with a pattern recognition method to find characteristic metabolites, and the metabolic targets were retrieved from the Kyoto Encyclopedia of Genes and Genomes database. Molecular docking technology was used to evaluate binding of isorhyncophylline to the core targets. The results of a principal components analysis (PCA) and partial least squares discriminant analysis (PLS-DA) showed a clear cluster of samples among three groups. There were seven differentially altered metabolites, and glucose metabolism and glutamate metabolism were the principal related pathways. Molecular docking indicated that isorhyncophylline had good binding properties with nine key candidate target proteins. According to the above research results, isorhyncophylline can influence energy metabolism and glutamate metabolism in the hippocampus.

The quality markers(Q-markers) of Shujin Huoxue Capsules were comprehensively discriminated based on the five principles of transfer and traceability, specificity, compatibility, effectiveness and measurability. The compounds that could be transferred from the original medicinal materials to the preparation were selected with the principle of transfer and traceability. The specific components in the prescription were screened by reviewing literature with the principle of specificity. According to the principle of compatibility, the attributes of compounds were evaluated by the sovereign, minister, assistant and guide combination rules of the original medicinal materials in the prescription. According to the principle of measurability, the measurable components were summarized by reference to the pharmacopoeia and literature combined with the content. The mechanism of Shujin Huoxue Capsules in the treatment of osteoporosis was studied through network pharmacology based on the principle of effectiveness, which was the evaluation index of effectiveness. The chemical components screened out above were regarded as candidate Q-markers, and the cobweb model was plotted to obtain the comprehensive score of Q-markers. Hydroxysafflor yellow A, trachelosid, eleutheroside B, α-cyperone, protocatechuic acid, protocatechualdehyde and 4-methoxy salicylaldehyde were discriminated as the Q-markers of Shujin Huoxue Capsules based on the five principles combined with cobweb model.

Meta-analysis of effect of Qishen Yiqi Dripping Pills combined with Western medicine on adverse cardiovascular events and quality of life after percutaneous coronary intervention / 中国中药杂志

To systemically evaluate the effect of Qishen Yiqi Dripping Pills combined with Western medicine on adverse cardiovascular events and quality of life after percutaneous coronary intervention(PCI). A total of 7 Chinese and English databases including CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library and Web of Science were searched by computer to collect the randomized controlled trials(RCTs) on Qishen Yiqi Dripping Pills combined with Western medicine in the treatment of patients with coronary heart disease after PCI with the retrieval time from the database establishment to April 1, 2020. Two researchers independently conducted li-terature screening, data extraction and bias risk assessment. Then, Meta-analysis was performed by using RevMan 5.3 software. A total of 31 RCTs were included, involving 3 537 patients. The results of Meta-analysis showed that in terms of major adverse cardiovascular events(MACE) after PCI, the combination of Qishen Yiqi Dripping Pills could significantly reduce the recurrence of angina pectoris, incidence of arrhythmia, heart failure and re-revascularization, and the effect was better than that of Western medicine treatment alone. However, there was no significant difference between the two groups in the improvement of non-fatal myocardial infarction, cardiac death, stent restenosis, stroke and other adverse cardiovascular events. In terms of improving left ventricular ejection fraction(LVEF), 6 min walking test(6 MWT), high-sensitivity C-reactive protein(hs-CRP) and Seattle angina pectoris scale(SAQ), the combination of Qishen Yiqi Dripping Pills and Western medicine treatment had obvious advantages over Western medicine treatment alone in increasing LVEF, 6 MWT and SAQ, and reducing the level of hs-CRP, with statistically significant differences. There were few adverse reactions in both groups, and there was no significant difference between the two groups. The main manifestations were gastrointestinal reactions, rash, gingiva and other small bleeding, and no serious adverse reactions occurred. The above reactions could disappear after drug withdrawal or symptomatic treatment. The application of Qishen Yiqi Dripping Pills combined with Western medicine in the treatment of patients after PCI could reduce the occurrence of MACE, improve the clinical efficacy, quality of life and prognosis in a safe and reliable manner. However, due to the quantity and quality limitations of included studies, more standardized, rigo-rous and high-quality clinical studies are still needed to further verify the above conclusions.

The molecular mechanism by which the circadian rhythm regulates body metabolism and research progress on intervention in the circadian rhythm by traditional Chinese medicine / 药学学报

Circadian rhythm is an internal regulatory mechanism that allows organisms to adapt to circadian changes in the external environment, and can regulate the body's steady state by affecting the metabolic pathways of multiple organs. When exogenous factors such as eating time, worktime changes, and sleep disturbances cause the body's circadian rhythm to be disrupted, the risk of developing metabolic syndrome is significantly increased. This article explores the relationship between circadian rhythm and body metabolism and summarizes the molecular mechanisms by which circadian rhythm regulates the digestive system, liver and bile acid production, and kidney function. We review research progress on intervention in the circadian rhythm by traditional Chinese medicine and provide a reasonable and valuable basis for follow-up studies on the role of traditional Chinese medicine in research on the molecular mechanisms of regulation of circadian rhythm.

Research progress on animal models of chronic pain and its application in traditional Chinese medicine research / 中国中药杂志

The classification of chronic pain is complex and its pathogenesis is not clear, which led to the limited progress of treatment measures.Traditional Chinese medicine(TCM) has certain advantages in the treatment of chronic pain, and its mechanism needs further exploration. The ideal animal model is helpful to elucidate the key mechanism of the occurrence and development of chronic pain and play an important role in the discovery of new drug targets, the development of new therapies and the research on the analgesic mechanism of TCM.In recent years, many scholars at home and abroad have done a lot of research to explore the pathogenesis of chronic pain and the mechanism of TCM, which have achieved some results. On this basis, this study summarizes the selection of experimental animals for chronic pain and the commonly evaluation methods of animal models. According to the latest international classification of diseases, this review organizes the induced methods, evaluation indicators, advantages and disadvantages of seven kinds of chronic pain animal models, such as chronic primary pain, chronic cancer-related pain and so on. Next, this review introduces the chronic pain animal models commonly used in TCM research, in order to provide guidance for the targeted selection of animal models when carrying out relevant experiments in the future.

Research progress of natural non-alkaloids with analgesic activity / 中国中药杂志

Pain is a complex, unpleasant feeling and emotional experience associated with actual or potential tissue damage, and manifests itself in certain autonomous psychological and behavioral responses. The commonly used opioid and non-steroidal anti-inflammatory analgesics(NSAIDs) may cause adverse reactions to the kidney, liver, cardiovascular or gastrointestinal system and cause problems of drug abuse. Therefore, it is necessary to study new analgesic drugs with less side effects and significant analgesic effects. A variety of natural products derived from terrestrial plants, microorganisms, marine organisms and fungi have been an important source of clinical medicines and provide an inexhaustible resource for the development and innovation of modern medicines. Therefore, this paper mainly reviews the natural non-alkaloids with analgesic activity in order to provide reference for the research and development of analgesic drugs derived from natural products.

Research progress of natural alkaloids with analgesic activity / 中国中药杂志

Pain is a protective defense response of the body to harmful stimuli. Long-term pain not only seriously affects the body of the patient and brings great pain to the patient, but also brings huge economic burden to the patient's family and society. It has become one of the most serious problems affecting human health. At present, opioids and non-steroidal anti-inflammatory drugs(NSAIDs) are commonly used as painkillers, but they tend to cause a variety of adverse reactions or risk of addiction. To find and develop new analgesic drugs, which are safer and more effective, has become the hot spot and difficulty in medical research. A variety of alkaloids derived from terrestrial plants, microorganisms, marine organisms and fungi have been an important source of clinical analgesic medicines. Various alkaloids have been proved to have good analgesic effects, such as morphine and the related to opioids, the main analgesic active components from Corydalis Rhizoma and Aconiti Lateralis Radix Praeparata. Here we summarized the research progress of natural alkaloids with analgesic activity, in order to provide reference for the research and development of analgesic drugs based on natural products.

Functionality-Independent DNA Encoding of Complex Natural Products.

DNA encoded chemical libraries (DELs) link the powers of genetics and chemical synthesis via combinatorial optimization. Through combinatorial chemistry, DELs can grow to the unprecedented size of billions to trillions. To take full advantage of the DEL approach, linking the power of genetics directly to chemical structures would offer even greater diversity in a finite chemical world. Natural products have evolved an incredible structural diversity along with their biological evolution. Herein, we used traditional Chinese medicines (TCMs) as examples in a late-stage modification toolbox approach to annotate these complex organic compounds with amplifiable DNA barcodes, which could be easily incorporated into a DEL. The method of end-products labeling also generates a cluster of isomers with a single DNA tag at different sites. These isomers provide an additional spatial diversity for multiple accessible pockets of targeted proteins. Notably, a novel PARP1 inhibitor from TCM has been identified from the natural products enriched DEL (nDEL).

Adsorption characteristics of Cu(II) and Zn(II) by nano-alumina material synthesized by the sol-gel method in batch mode.

This study mainly focuses on the preparation, characterization, and sorption performance for Cu(II) and Zn(II) by using nano-alumina material (NA) synthesized through the sol-gel method. The SEM, EDS, FT-IR, and XRD analysis methods were implemented to identify the micromorphology and crystal structure of the synthesized NA absorbent and its structure after the adsorbing procedure. The effect of effective variables including various absorbent dose, contact time, initial ion concentration, and temperature on the removal of Cu(II) and Zn(II) from aqueous solution by using NA was investigated through a single factor experiment. Kinetic studies indicated that adsorption of copper and zinc ions by NA was chemical adsorption. The adsorption isotherm data were fitted by Langmuir (R2: 0.919, 0.914), Freundlich (R2: 0.983, 0.993), and Temkin (R2: 0.876, 0.863) isotherms, indicating that copper and zinc ions were easily adsorbed by NA with maximum adsorption capacities of 87.7 and 77.5 mg/g for Cu2+ and Zn2+, respectively. Thermodynamic parameters indicated that the adsorption of Cu2+ was spontaneous(G<0) and the adsorption of Zn2+ might not be spontaneous (G > 0) by NA. Graphical abstract ᅟ.

[The protective effect of tea polyphenols on chronic alcoholic liver injury in rats].

OBJECTIVE: To investigate the protective effects and potential mechanisms of tea polyphenols intervention on excess alcohol intake induced liver injury in rats. This study established the animal model of chronic liver injury rats induced by alcohol. Our results will provide experimental evidence for the effects of tea polyphenol on chronic alcoholic liver injury. METHODS: Alcohol-induced liver injury rat models were established, and the tea polyphenols intervention was performed in the meantime. After 8 weeks, rats were anesthetized, and visceral fat and liver samples were separated, weighted and stored. Visceral fat content was evaluated in fat/body weight ratio. Liver lipid accumulation was assessed by liver index and the result of Oil Red O staining. Hepatic superoxide dismutase (SOD) activity, malondialdehyde (MDA) content, total antioxidant capacity assay (T-AOC) and glutathione peroxidase (GSH-Px) activity were detected. And fatty acid translocase (FAT/CD36) protein level in liver was detected. RESULTS: Compared with the control group rats, the fat/body weight ratio, SOD/MDA, T-AOC and GSH-Px activity of chronic liver injury rats were decreased significantly (P<0.05,P<0.01). Meanwhile the liver index, FAT/CD36 protein level and lipid deposition in liver of chronic liver injury rats were increased (P<0.01). Compared with chronic liver injury rats, the tea polyphenols intervention increased fat/body weight ratio (P<0.05), and significantly increased SOD/MDA, T-AOC and GSH-Px activity (P<0.01). Meanwhile the tea polyphenols intervention reduced liver index (P<0.01), FAT/CD36 protein level (P<0.01) and lipid deposition in liver. CONCLUSIONS: Tea polyphenols intervention can improve lipid deposition and oxidative stress in chronic alcoholic liver, which is concurrent with decreased FAT/CD36 protein expression on the hepatocyte membrane.

Systematic Reviews/Meta-Analyses of Integrative Medicine in Chinese Need Regulation and Monitoring Urgently and Some Suggestions for Its Solutions / 中国结合医学杂志

With the introduction and development of evidence-based medicine in China, it has been spread rapidly in the area of integrative medicine (IM) and has become a new unique discipline. During almost 20 years, as one of the most important parts of evidence-based IM, systematic review (SR)/meta-analysis (MA) of IM have shown a good development momentum in the aspects of quantity, depth, breadth and influence, but also face the harsh situation of the uncontrolled quantity and quality, especially for SRs in Chinese. Therefore, how to supervise and standardize this area effectively becomes a problem to be solved. Based on the experience both at home and abroad, the authors put forward several kinds of solutions for laying the foundation for further development such as promoting the registration system of SR/MA of IM, effectively setting up the regulatory platform of quality and quantity, launching professional training for SR/MA reviewers, forming qualification registration, developing the data transfer and sharing platform to realize the transparency of evidence process.
