ABSTRACT
ObjectiveTo explore the clinical application law and provide literature support and development ideas for the modern application of fresh Plantaginis Herba. MethodThe literature about the application of fresh Plantaginis Herba was retrieved from the fifth edition of Chinese medical dictionary， China national knowledge infrastructure （CNKI）， VIP， Wanfang data， and Chinese medical journals and analyzed. ResultFresh Plantaginis Herba appeared frequently in ancient books， with the effects of clearing heat， cooling blood， promoting urination， and relieving stranguria. It was used for the treatment of stranguria， urine retention， bloody urine， sore and carbuncle， epistaxis， red and swelling eye， suppurative inflammation in the throat， and gynecological and pediatric diseases. According to modern medical publications， fresh Plantaginis Herba is mainly used to treated diseases in the kidney， five sense organs， spleen， stomach， lung， liver， gallbladder， and skin and gynecological and pediatric diseases. Specifically， it is mainly used to treat the syndrome of dampness and heat in kidney and skin diseases caused by the accumulation of dampness and heat toxin， with the effects of clearing heat， removing toxin， promoting urination， and relieving stranguria. Since ancient times， there have been reports of using fresh Plantaginis Herbausing for food and health care. ConclusionFresh Plantaginis Herba is widely used in clinical practice and has a high medical value and economic value. However， its modern application lags behind， so it is necessary to promote the development of fresh Plantaginis Herba from the aspects of medicinal material production， storage， transportation， preparation research and development， and clinical application.
ABSTRACT
With the change in environmental pollution and lifestyle， the incidence and mortality of cancer are increasing year by year， which is a serious threat to human life and health. Autophagy is a process in which eukaryotic cells use lysosomes to degrade cytoplasmic proteins and damaged organelles under the regulation of autophagy-related genes. It plays a dynamic inhibiting or promoting role in the occurrence and development of cancer and is involved in the regulation of tumor formation， proliferation， metastasis， and response to anticancer therapy. With the deepening of the research on the mechanism of cancer， a variety of cancer treatment methods have been established， such as chemotherapy， radiotherapy， surgery， immunotherapy， and gene therapy. Pharmacological or genetic inhibition of autophagy has been shown to enhance the lethal effect of various anticancer treatments on tumor cells， suggesting that inhibition of autophagy is an effective sensitization strategy in cancer therapy. Meanwhile， over-stimulation of autophagy may also provide a new method for the treatment of drug-resistant cancer cells with high apoptotic thresholds. As a treasure of Chinese culture， traditional Chinese medicine plays an important role in the adjuvant treatment of cancer with its advantages of multi-target， multi-pathway， and small side effects. In recent years， many positive results have been achieved in the study of natural autophagy regulatory factors of traditional Chinese medicine in cancer， and they have been widely verified in different autophagy regulatory models. This article outlines the mechanism of autophagy， summarizes the dual regulatory role of autophagy in tumor biology， and collects relevant studies published in the databases of China National Knowledge Infrastructure (CNKI） and Wanfang Data for nearly 10 years that affect the role of tumorigenesis and development by regulating autophagy. The article also collates autophagy rules of tumor cells induced by traditional Chinese medicine and its active ingredients， so as to provide a certain reference for the research on the development and application of anti-tumor drugs.
ABSTRACT
ObjectiveTo collect and analyze the properties and application characteristics of external use of roots and rhizomes of Chinese herbal medicines in the Chinese Materia Medica（《中华本草》） to provide data references for the research on clinical external use of Chinese medicine， in order to provide data reference for clinical external use of traditional Chinese medicine（TCM）. MethodThe Chinese herbal medicines included in the Chinese Materia Medica were systematically screened. The inclusion criterion was the explicit mention of terms like "root", "rhizome", "root bark", "tuber", "tuberous root", etc. under the "Source" in the Chinese Materia Medica. Information on properties, flavors, meridian tropism, medicinal parts, fresh use, toxicity, efficacies and indications, and dosage of roots and rhizomes of Chinese herbal medicines was collected. The information was then entered into an Excel spreadsheet for statistical analysis. ResultThe Chinese Materia Medica records 2 662 roots and rhizomes of Chinese herbal medicines, of which 1 653 are suitable for external use. The predominant properties and flavors are cool, cold, bitter, pungent, and sweet. These Chinese herbal medicines mainly act on the liver, lung, and spleen meridians. The primary medicinal parts used include root, rhizome, and root bark. More than half of the roots and rhizomes of Chinese herbal medicines can be used in their fresh form. The main efficacies include clearing heat, removing toxins, resolving stasis, dispersing accumulation, resolving blood stasis and stopping bleeding, reducing swelling and alleviating pain, dispelling dampness and relieving pain. The main indications are skin sores, traumatic injuries, and rheumatic diseases. Common external application methods include poultice, decoction for washing, and applying powdered form. Most of these Chinese herbal medicines lack specific dosage guidelines for external use, with an emphasis on using an appropriate amount. ConclusionThe Chinese Materia Medica contains a wide range of roots and rhizomes of Chinese herbal medicines suitable for external use, with definite therapeutic effects, providing a broad perspective for the application of Chinese medicine externally. However, there are still problems such as unclear dosages and limited research. Further studies are necessary to better utilize the advantages of the external use of Chinese medicine.
ABSTRACT
Chinese herbal medicines play a great role in disease prevention and treatment， while some may cause adverse effects on the human body after of long-term application. Liver injury， one of such adverse effects， is an important check item in the development of new Chinese medicines for clinical application and has become a major reason for the withdrawal of many listed drugs from the market. With the rising concern about the safety of Chinese herbal medicines， studies about liver injury caused by herbal medicines are increasing. Most of the studies focus on liver injury caused by Chinese herbal medicines or their ingredients. To improve the safety of Chinese herbal medicines， this paper summarizes the material basis and mechanisms of several Chinese herbal medicines that cause liver injury and the measures to reduce liver injury. These measures include reducing the dose and course of administration， changing the route of administration， and altering the dosage form， compatibility， and processing. In addition， this paper introduces the biological effects and mechanisms of single Chinese herbal medicines， Chinese medicine prescriptions， and active components in the prevention and treatment of liver injury. Furthermore， this paper proposes the safe dose and efficacy-toxicity boundary of Chinese herbal medicines that may cause liver injury by referring to the modern research on toxicity reduction， clarifies the mechanisms of toxicity reduction measures， and determines the material basis of liver injury induced by Chinese herbal medicines， which will ensure the safe application of herbal medicines in clinical practice. Finally， this paper suggests that efforts should be made to strengthen the clinical research on the prevention and treatment of liver injury and elucidate the scientific connotation of the prevention and treatment of liver injury by Chinese herbal medicines by using modern science and technology， aiming to provide a scientific basis for the clinical prevention and treatment of liver injury.
ABSTRACT
ObjectiveTo analyze the functions， formulae， dosage forms， and methods of administration of the menstruation-regulating Chinese patent medicines included in the 2020 edition of the Chinese Pharmacopoeia， so as to provide reference for rational clinical use. MethodThe relevant Chinese patent medicines were recorded one by one， and the efficacy， dosage forms， methods of administration， and contraindications were counted， classified， and summarized. Further， we analyzed the Chinese medicines used in these Chinese patent medicines， identified the high-frequency Chinese medicines for menstrual regulation， and analyzed their natures， tastes， meridian tropism， and functions， aiming to guide the clinical use. ResultA total of 142 Chinese patient medicines for menstrual disorders were included in this study. They were classified into 12 categories according to their efficacy， mainly for regulating menstruation and blood， tonifying， activating blood， and eliminating mass. The representative Chinese patent medicines were Bazhen Yimu pills， Shaofu Zhuyu pills， Lyujiao Buxue granules， and Guizhi Fuling pills， which are in line with the principles of moving Qi and blood and regulating liver and spleen. Menstruation-regulating Chinese patents medicines are mostly in pills and capsules and are mainly taken with yellow wine or ginger decoction. Pregnancy was the contraindication with the highest frequency， followed by menstruation and dietary precautions. The high-frequency Chinese medicines mainly had the functions of tonifying， activating blood， resolving stasis， and clearing heat， with the top three being Angelicae Sinensis Radix， Paeoniae Radix Alba， and Chuanxiong Rhizoma. These medicines mainly had warm nature， sweet， bitter， and pungent tastes， and tropism to liver and spleen meridians. ConclusionThe treatment of menstrual disorders should focus on nourishing and activating blood， regulating Qi， tonifying kidney， supporting spleen， nourishing liver， and harmonizing stomach. The appropriate dosage form should be selected according to the patient's specific conditions. The medicinal guide and the method of administration should be selected on the basis of syndrome differentiation with attention to the contraindications. In summary， the Chinese patient medicines for menstrual regulation should be chosen based on the patient’s syndrome under guidance of the theory of traditional Chinese medicine.
ABSTRACT
Cerebral ischemia-reperfusion is a serious cerebrovascular disease with high morbidity and mortality. In recent years， reperfusion therapy based on thrombolysis and thrombectomy has been the main treatment method for patients with ischemic stroke. Numerous studies have shown that Chinese medicine saponins can effectively interfere with cerebral ischemia-reperfusion in a multi-target and multi-way manner， which have great potential on the treatment and prevention of cerebral ischemia-reperfusion. Taking China National Knowledge Infrastructure （CNKI） literature database and Wanfang literature database as the analysis sources， this paper used SPSS statistics to summarize the number of papers on the treatment of cerebral ischemia-reperfusion with Chinese medicine saponins and CiteSpace to conduct cluster analysis on the high-frequency keywords of the research， thereby expounding the research hotspots and research status of Chinese medicine saponins in the treatment of cerebral ischemia-reperfusion. Based on literature analysis and summary of animal experiments on the treatment of cerebral ischemia-reperfusion with Chinese medicine saponins in the past two decades， Chinese medicine saponins exerted effects by anti-inflammation， inhibition of oxidative stress， immune regulation， protection of nerve cells， inhibition of thrombosis， promotion of thrombolysis， protection of mitochondria， blood-brain barrier repairing， and other ways. The specific mechanism， therapeutic effect， and signaling pathway of each Chinese medicine saponin have been summarized in this study， which provide a theoretical basis for the in-depth research， new drug development， and clinical application of Chinese medicine saponins for the treatment of cerebral ischemia- reperfusion.

ABSTRACT
ObjectiveTo explore the macroscopic medication pattern of traditional Chinese medicine （TCM） in treating esophageal cancer （EC） and provide medication references for the clinical application of TCM in EC treatment. MethodRelevant literature on TCM treatment of EC was retrieved from three major Chinese databases： China National Knowledge Infrastructure （CNKI）， Wanfang Data， and VIP. Information about Chinese herbal medicines was entered into Excel to establish a prescription database for EC. The data were standardized， summarized， and subjected to frequency analysis， association rules， and cluster analysis of medication in the prescriptions. Based on the TCM classification of EC syndromes， clinical indications corresponding to each syndrome were identified， and high-frequency drugs and drug pairs were analyzed correspondingly with syndromes. ResultA total of 136 prescriptions containing 240 Chinese herbal medicines were screened， with a cumulative frequency of 1 853 times. The top 5 frequently used Chinese herbal medicines were Glycyrrhizae Radix et Rhizoma， Poria， Atractylodis Macrocephalae Rhizoma， Astragali Radix， and Pinelliae Rhizoma. In terms of functions， the Chinese herbal medicines were mainly deficiency-tonifying， urination-promoting and dampness-draining， deficiency-tonifying， deficiency-tonifying， and phlegm-resolving and cough and dyspnea-relieving ones. The statistical analysis of flavor， property， and meridian tropism showed that Chinese herbal medicines were mainly bitter and sweet， warm， cold， and neutral， and acted on the spleen， lung， and stomach meridians. Association rule analysis yielded nine potential drug combinations， and cluster analysis of high-frequency drugs resulted in four combination categories. The four TCM syndromes for EC corresponded to respective clinical indications， treatment drugs， and drug pairs. ConclusionTonifying deficiency， reinforcing healthy Qi， descending adverse Qi， resolving phlegm， activating blood， and resolving stasis are the basic principles of TCM treatment for EC， which are supplemented by clearing heat and dissipating mass while focusing on regulating and smoothing the qi movement. The drug combinations obtained from high-frequency drug and association rule analysis provide references for different TCM syndrome treatments of EC， offering valuable insights for clinical medication.
ABSTRACT
Fibrosis refers to the disorder of repair response after tissue damage， which is mainly characterized by the increase of fibrous connective tissue and the decrease of parenchymal cells in organs. Progressive fibrosis can lead to the destruction of tissue structure and organ failure. Ferroptosis is a new type of programmed cell death， which is caused by the accumulation of iron dependent lipid peroxides and regulated by iron metabolism， iron autophagy， amino acid metabolism and lipid metabolism. Ferroptosis plays an important role in the pathological process of fibrosis， participating in many pathological processes such as organ parenchymal cell injury， macrophage inflammation， oxidative stress and myofibroblast transformation. Studies have shown that ferroptosis occurs in myofibroblasts during extracellular matrix deposition in the fibrous cascade reaction， and the targeted regulation of ferroptosis can effectively reduce chronic organ injury and tissue fibrosis. It has been confirmed that a variety of traditional Chinese medicine and its active components can regulate the ferroptosis parenchyma cells of organs and play an anti-fibrosis effect， showing a good research prospect. This article summarizes the role of ferroptosis in the pathological process of liver， lung， kidney and heart fibrosis and the intervention of related Chinese medicine， in order to provide a new target for Chinese medicine to prevent and treat fibrosis.

ABSTRACT
In recent years， as people's diets have changed and diversified， the incidence of dental arthritis has increased year by year， seriously affecting the quality of life of patients. Therefore， the prevention and treatment of dental arthritis should be emphasized. To further study the pathogenesis of dental arthritis and the development and screening of therapeutic drugs， this paper summarized and analyzed the modeling methods， mechanisms， as well as the advantages and disadvantages of the existing animal models of dental arthritis. The clinical diagnostic criteria of traditional Chinese medicine （TCM） and western medicine was established， and the compatibility of TCM and western medicine anastomosis in animal models was evaluated. The results showed that the gel perfusion model had a good match between TCM and western medicine， with simple operation and short cycle. By combining the pathogenic factors of TCM and western medicine， the models of kidney deficiency and stomach heat with kidney deficiency in TCM were obtained， which fully reflected the clinical syndrome characteristics of TCM and western medicine， thus simulating the pathogenesis of human natural dental arthritis. Besides， ligation line model， as the most commonly-used animal model of dental arthritis with a good match to western medicine， was mature and highly repeatable， and had a high success rate. Ligation line model was widely used in various periodontal disease studies， but it did not involve the pathogenic factors of TCM. The current animal model of dental arthritis is given priority to western medicine disease model， and the combination of disease and model is rare， which cannot meet the requirements of the syndrome characteristics of TCM. Only an animal model of dental arthritis with TCM syndrome that conforms to the clinical syndrome characteristics effectively assists to study the nature of TCM syndrome and develop innovative Chinese medicine. Therefore， the establishment of an accurate and standardized animal model of dental arthritis combined with TCM and western medicine is still the focus of future study on the pathogenesis of dental arthritis. This study is intended to provide a certain basis for the discovery， screening， and evaluation of medicines for the treatment of dental arthritis.
ABSTRACT
Diabetes mellitus （DM） is a metabolic disease mainly characterized by chronic hyperglycemia and has multiple etiologies. The complications of DM， such as coronary atherosclerosis， nephropathy， foot disease and cardiac dysfunction， have high morbidity， disability rate and mortality. DM and its complications have a long course of disease and are easy to relapse， which are difficult to be cured， seriously affecting people's life and health. NOD-like receptor pyrin domain-containing 3 （NLRP3） inflammasome is an important component of inflammatory response and innate immune system. The inflammatory cascade induced by NLRP3 activation is involved in the occurrence and development of DM as well as its complications by releasing inflammatory factors， damaging endothelial cells and affecting metabolic stress. Therefore， as the core of the inflammatory response， NLRP3 may provide a new target for the treatment of DM and its complications. Traditional Chinese medicine plays a key role in the treatment of DM and its complications， and has a regulatory effect on NLRP3. Thus it has become a novel research strategy to prevent and treat DM and its complications via modulating NLRP3. However， at present， there are relatively scattered reports and a lack of systematic review on the role of traditional Chinese medicine in the treatment of DM and its complications from the perspective of NLRP3. As a result， this paper reviewed domestic and foreign literature in recent years and conducted the discussion from two aspects： the influence of NLRP3 on the occurrence and development of DM and its complications， and the progress of traditional Chinese medicine in intervening in DM and its complications through NLRP3. This paper provided reference for the research on the regulation of NLRP3 and a new direction for the treatment of DM and its complications.
ABSTRACT
ObjectiveEsophageal cancer is a common malignant tumor of the upper gastrointestinal tract， and has high incidence and mortality in China. Its incidence is increasing year by year， and survival rate is low， thus seriously threatening human life and health. To further explore the pathogenesis of esophageal cancer and its systematic and efficient diagnosis and treatment methods， the animal models of esophageal cancer was evaluated according to the animal model evaluation method previously established by our team based on the characteristics of its clinical symptoms of traditional Chinese and western medicine， and suggestions for model improvement were proposed. MethodThe existing animal models of esophageal cancer were summarized through China National Knowledge Infrastructure （CNKI） and Wanfang Data. The relevant indexes of the models were assigned， and their coincidence with the clinical diagnostic guidelines of traditional Chinese and western medicine for esophageal cancer was evaluated. ResultExcept the spontaneous animal model of esophageal cancer with high clinical coincidence adopted in few studies， the animal model induced by methylbenzylnitrosamine was in good agreement with the clinical data， which simulated the etiology and pathogenesis of esophageal cancer to a certain extent. The model partially reflected some indicators of clinical diagnosis in western medicine， and also indicated the body weight loss， purple nail and increased number of drinking in traditional Chinese medicine （TCM）. However， there was still a lack of differentiation of TCM syndromes. ConclusionOn the basis of the original model， the animal model induced by methylbenzylnitrosamine and the mouse model of xenogeneic gastric wall transplantation of human esophageal cancer cells were applied， which were intervened with the factors of phlegm and qi mutual obstruction syndrome， blood stasis and phlegm stagnation syndrome， Yin deficiency and internal heat syndrome and Qi deficiency and yang weakness syndrome， and were distinguished to reflect the performance of TCM syndrome. The animal model of esophageal cancer combined with TCM syndrome was thus obtained， which embodied the clinical symptoms of esophageal cancer in TCM， and the characteristics of the animal model combined with TCM syndrome， and simulated the clinical practice of traditional Chinese and western medicine， providing an accurate pathological model carrier for basic research.
ABSTRACT
ObjectiveTo explore the pharmacodynamic effects of total flavonoids of Paeonia suffruticosa flower （TFPFs） on rats with hyperuricemia and provide scientific data support for the research and development of therapeutic drugs for hyperuricemia. MethodThe hyperuricemia model was induced by adenine combined with ethambutol in rats. The rats were randomly divided into a blank control group， a model group， two positive control groups （allopurinol at 42 mg·kg-1 and Tongfengshu tablets at 600 mg·kg-1）， and high-， medium-， and low-dose TFPFs groups （260， 130， and 65 mg·kg-1）. The general conditions of rats were observed and recorded， and the body weight was recorded once every 5 days. The 24-hour urine volume， water intake， uric acid （UA）， and urinary protein of rats were determined after the last administration. The kidney index was calculated. The pathological changes in thymus and spleen tissues of rats were observed by hematoxylin-eosin （HE） staining. The serum activities of UA， creatinine （Cr）， blood urea nitrogen （BUN）， malondialdehyde （MDA）， superoxide dismutase （SOD）， and total antioxidant capacity （T-AOC） of rats were determined. The xanthine oxidase （XOD） and adenosine deaminase （ADA） activities in the liver were detected. The content of uric acid transporter 1 （URAT1）， organic anion transporter 1 （OAT1）， and glucose transporter 9 （GLUT9） in the kidney was detected by enzyme-linked immunosorbent assay （ELISA）. ResultCompared with the results in the model group， TFPFs could improve the mental state of rats， increase the body weight（P<0.01）， promote UA excretion（P<0.01）， reduce the content of urinary protein（P<0.05）， relieve renal glomerular atrophy， renal tubular epithelial cell status， and urate crystal deposition in renal tubules， dwindle 24-hour urine volume， water intake， kidney index（P<0.05）， serum levels of UA， Cr， BUN， and MDA（P<0.05，P<0.01）， inhibit the activities of XOD（P<0.05） and ADA（P<0.05，P<0.01）in the liver， diminish the expression of GLUT9 in the renal homogenate（P<0.05）， and increase serum SOD and T-AOC activities as well as OAT1 expression（P<0.01） in the kidney. The pathological changes of thymus and spleen were improved. ConclusionTFPFs possess a protective effect on the kidney of rats with hyperuricemia， which is achieved by promoting uric acid excretion， inhibiting oxidation and the activity of key enzymes in uric acid synthesis， and regulating the expression of uric acid transporters.

ABSTRACT
OBJECTIVE:To study the effects of total glucosides of Verbena officinalis on chronic nonbacterial prostatitis (CNP)in mice and its anti-inflammatory and analgesic effects. METHODS:60 mice were randomized into normal group(normal saline),model group(normal saline),positive group(Qianliekang tablet 1.5 g/kg)and total glucosides of V. officinalis high-dose, medium-dose and low-dose groups(0.2,0.1,0.05 g/kg),with 10 mice in each group. CNP model was induced in those groups ex-cept for normal group;mice were given relevant medicine once a day for consecutive 21 days since 8th day of modeling. The white blood cell count,lecithin corpuscle density and pathological changes of prostate samples were observed. 50 mice were randomly di-vided into model group(normal saline),positive group(Aspirin tablet 0.3 g/kg or Dexamethasone acetate tablet 0.01 g/kg)and to-tal glucosides of V. officinalis high-dose,medium-dose and low-dose groups(0.2,0.1,0.05 g/kg);they were given relevant medi-cine intragastrically once a day for consecutive 7 days. The xylene-induced ear swelling test (Aspirin tablet as positive drug) and cotton-pellet granuloma test (Dexamethasone acetate tablet as positive drug) were conducted to determine the the degree of ear swelling and the net weight of granuloma. The acetic acid writhing test and hot plate test(Aspirin tablet as positive drug)were car-ried out to determine the latency period of writhing,the times of writhing within 20 min and pain threshold. RESULTS:Compared with model group,white blood cells count of prostate tissue were lowered while the density of lecithin corpuscles were increased significantly in medicine groups;the pathology of prostate tissue were improved significantly in positive group and total glucosides of V. officinalis high-dose and medium-dose groups,and mostly were 0 and Ⅰ grade. The degree of ear swelling and the net weight of granuloma were markedly reduced in positive group and total glucosides of V. officinalis high-dose and medium-dose groups;the times of writhing within 20 min decreased in medicine groups,and the latency period of writhing prolonged and pain threshold in-creased in positive group and total glucosides of V. officinalis high-dose group. All of the results showed statistical difference(P<0.05 or P<0.01). CONCLUSIONS:Total glucosides of V. officinalis can improve CNP in mice,and shows good anti-inflammatory and analgesic effects.
