ABSTRACT

OBJECTIVE To analyze quality maker (Q-marker) of Ka nggongyan soft capsule (KSC). METHODS The fingerprints of 20 batches of KSC were established by ultra high performance liquid chromatography (UPLC)method. Similarity Evaluation System of TCM Chromatographic Fingerprint (2012 edition)were used to evaluate the similarity and confirm common peaks. The contents of norisoboldine ,leonurine hydrochloride ,forsythoside B ,acteoside,poliumoside and isoacteoside were determined by the same UPLC method. Targets and pathways related to KSC in the treatment of cervicitis were screened and analyzed by network pharmacology and molecular docking method to construct a “component-target-pathway”network,and analyze its potential Q-marker. RESULTS Twelve common peaks were identified in the fingerprints of 20 batches of KSC ,and the similarity was greater than 0.99. Six common peaks were identified ,including norisoboldine ,leonurine hydrochloride ,forsythoside B,acteoside,poliumoside and isoacteoside. The contents of the above 6 components were 1.336-1.774,0.093-0.143,4.970-5.888, 0.505-0.623,5.206-6.226 and 0.785-0.895 mg/g,respectively. By network pharmacology analysis ,14 key targets and 94 pathways were obtained ,and their binding energies to the core targets (protein kinase B 1,tumor necrosis factor )were all less than -6.4 kJ/cal. CONCLUSIONS Six components such as norisoboldine and leonurine hydrochloride are potential Q-marker of KSC.

ABSTRACT

As of 2020, there are more than 120 million diabetic patients in China. Diabetic wounds is one of the common complications of diabetes with increasing incidence and has the potential to cause disability and mortality. Traditional Chinese medicine (TCM) has a long history in treating diabetic wounds, demonstrating significant efficacy and safety. In recent years, increasing researchers have explored the mechanisms of polysaccharides from TCM in the repair of diabetic wounds. Polysaccharides are the main active ingredients of TCM and employ one or more blood sugar-lowering mechanisms. However, most studies focus on the repair mechanism of single polysaccharides, and there is little in-depth discussion and summary. To provide a new therapy for diabetic wounds, which meets international standards and has the characteristics of TCM, and provide reference for the clinical treatment of diabetic wounds, we reviewed relevant literature to summarize the mechanisms of TCM polysaccharides in treating diabetic wounds. The mechanisms include inhibiting inflammation to improve wound microenvironment, lowering blood sugar, promoting fibroblast migration and proliferation, regulating wound growth factor to promote angiogenesis, inhibiting oxidative stress response, and regulating immune function. Finally, we put forward some possible research directions in the future.

ABSTRACT

Paclitaxel is the first-line chemotherapy drug for a variety of cancers. However, the paclitaxel resistance greatly reduced the efficacy in the later treatment stage, which seriously increased the mortality and recurrence rate of cancer and limited the clinical application of paclitaxel. At present, Chinese medicine compound prescription, proprietary Chinese medicine, and Chinese medicine injection are widely used as the adjuvant chemotherapy drugs for the treatment of cancer in clinic. Chinese medicine has shown unique advantages in improving the efficacy of chemotherapy drugs and the prognosis of chemotherapy, and reducing the toxic and side effects. However, the specific mechanism and effective monomer composition of Chinese medicine for reversing the resistance of chemotherapy drugs are unclear, and the application of Chinese medicine in different types of cancer is also limited, which are worthy of further exploration. This review summarized the composition of Chinese medicine monomer with synergistic antitumor effect combined with paclitaxel in recent years. The specific mechanism and pharmacological activities of Chinese medicine monomer reversing paclitaxel resistance were classified. This review found that through acting on the membrane transport protein, Chinese medicine monomer promoted the accumulation of paclitaxel in tumor cells, inhibited the expressions of protein and metabolic enzyme related to multidrug resistance and the metabolism of paclitaxel, and regulated the levels of apoptosis genes and factors and apoptosis-related pathways to promote the inhibitory effect of paclitaxel on cell proliferation. Chinese medicine monomer also significantly improved paclitaxel chemotherapy sensitivity by regulating the expression levels of micro ribonucleic acid (microRNA) and long non-coding ribonucleic acid RNA (lncRNA), inhibiting the characteristics of tumor stem cells and tumor metabolic reprogramming, improving tumor microenvironment, and triggering tumor cell death autophagy and oxidative stress response. This review provides a theoretical basis for clarifying the specific anti-tumor mechanism of Chinese medicine monomer combined with paclitaxel, which is of great significance for the development of new Chinese medicine and the clinical research of the drugs combined with paclitaxel, and has certain value for the application of Chinese medicine combined with other chemotherapy drugs.

ABSTRACT

Traditional Chinese medicine (TCM), which owns abundant chemical components and complex action pathways, has been widely recognized in the prevention and treatment of diseases. Some analysis methods have been emerged in order to ensure the quality of TCM and to develop new TCM drugs. Matrix-assisted laser desorption ionization mass spectrometry (MALDI-MS) is a soft ionization mass spectrometric technique with the advantages of high throughput, high sensitivity, low cost and so on. It provides technical support for the molecular level study on TCM. At present, this technique has been used in the field of composition analysis and metabonomics research of TCM, and plays an important role in the identification of Chinese herbal medicines, real-time molecular screening and the construction of metabolic network pathway of active ingredients. Among them, the selection of appropriate matrix and sample preparation technology is the key to ensure the detection effect of MALDI-MS. With the development and optimization of new matrix, the continuous improvement of sample preparation technology and the combination of MALDI-MS with various analytical methods will greatly improve the detection effect. Based on this, this paper discusses the application of MALDI-MS in TCM, including high-throughput detection of active ingredients in TCM, monitoring of the original medicines and their metabolites in vivo, and in situ visualization and characterization of tissue distribution information of active ingredients in TCM. It also discusses the application prospect and existing problems of MALDI-MS in TCM, so as to provide technical support for the identification of active ingredients in TCM, drug utilization and metabolism.

ABSTRACT

Through consulting the ancient herbal medicine, prescription books and medical books, combined with modern relevant literature, standards and other information, this paper made a textual research on the name, origin, producing areas, harvesting and processing methods of Astragali Radix according to different historical development periods, providing a basis for the development of famous classical formulas containing Astragali Radix. According to the textual research, the original name of Astragali Radix is Huangqi, and "Qi" originally refers to the medicinal material Zhimu. Some people began to mistake it for Huangqi in the Ming dynasty, and then gradually used Astragali Radix as a medicinal material. The mainstream basis of Astragali Radix can be determined as the dried roots of Astragalus membranaceus var. mongholicus or A. membranaceus. In different historical periods, A. floridus, A. chrysopterus, A. emestii and other plants of Astragalus or even non-Astragalus were used as local Astragali Radix. The earliest production areas of Astragali Radix were Sichuan, Shaanxi, and Gansu, and then gradually expanded to the northeast. Since the Song dynasty, Mianqi in Shanxi province has been regarded as the genuine variety. In the Qing dynasty, besides Shanxi province, Inner Mongolia was also regarded as a genuine place. In the Republic of China, Huangqi produced in northeast China was praised highly. It is mainly produced in Shanxi, Inner Mongolia, Gansu, northeast and other provinces. The main commodity is cultivated products, and the quality of wild imitation cultivation in Datong and Xinzhou is better than other places. There are many processing methods of Huangqi recorded in the materia medica and prescription books, most of which are raw products, and honey processing is the mainstream of processed products. Based on the current situation of resource cultivation and production, 11 famous classical formulas in The Catalogue of Ancient Famous Classical Formulas (The First Batch) containing Huangqi suggested that all use A. membranaceus var. mongholicus, especially those from Datong and Xinzhou in Shanxi Province. In addition to honey processing of Qingxin Lianziyin, it is suggested to use raw products for other formulas.

ABSTRACT

Through consulting the ancient and modern literature, this paper makes a textual research on the name, origin, producing area, harvesting and processing of Poria, so as to provide a basis for the development of the famous classical formulas containing this medicinal material. The description of Poria and the characteristics of the attached figures in the Chinese herbal literature of the past dynasties are consistent with Poria cocos. The medicinal parts are dried sclerotia or P. cocos peel. Poria was originally produced in Taishan, Shandong province. In the Tang dynasty, along with the change of pine forest resources, producing area of Poria was transferred to Huashan area in Shaanxi province. In the Ming dynasty, the authentic producing area was transferred to Yunnan, and has continued to now. In ancient times, the processing methods of Poria were steaming, boiling, slicing, mashing and other subsequent processing after peeling. It is suggested that Poria in famous classical formulas should be sliced according to the 2020 edition of Chinese Pharmacopoeia.

ABSTRACT

Through consulting the ancient and modern literature, this paper makes a textual research on the name, origin, producing area, harvesting and processing methods of Asini Corii Colla, so as to provide a basis for the development of the famous classical formulas containing the medicinal material. Before the Tang dynasty, cow leather was the main source of Asini Corii Colla, and donkey was rare as an introduced species. From the end of Tang dynasty to Song dynasty, due to the development of doctors' understanding of the properties and effects of medicines, with the increase of the number of donkeys and the limitation of the use of cow leather, the source of Asini Corii Colla changed from cow leather to donkey skin. During the Ming and Qing dynasties, the theory of medicine property was further developed, and all doctors basically agreed that black donkey skin and E-well water were two essential factors for making genuine Asini Corii Colla. Therefore, it is suggested that Asini Corii Colla should take Equus asinus as the authentic origin in the development of the famous classical formulas, attach importance to the quality of water source, take Liaocheng in Shandong province as the authentic producing area, and the processing should be carried out in accordance with the requirements of the 2020 edition of Chinese Pharmacopoeia.

ABSTRACT

This paper made a systematic textual research on the historical evolution and changes of the name, origin, producing area, harvesting and processing methods of Jujubae Fructus used in famous classical formulas by referring to the ancient literature, so as to provide a basis for the sampling and research of the formulas containing the medicinal materials. According to textual research, there are many names of Jujubae Fructus, most of which are named by characters or producing areas, which are called Dazao. Ziziphus jujuba has always been the mainstream variety in all dynasties, and Z. jujuba var. inemmis has also been used. Considering that the differences between the two are not obvious, we can use Z. jujuba and Z. jujuba var. inemmis as the origins of Dazao. The germplasm resources of Jujubae Fructus are rich, which are distributed all over the country. Qingzhou (now Shandong), Jinzhou (now Shanxi) Jiangzhou (now Shanxi), Puzhou (now Shanxi) have been recorded as authentic producing areas of Jujubae Fructus in the past dynasties, especially in Shandong. At the beginning of the 21st century, the planting of Jujubae Fructus in Xinjiang gradually developed, and now has a high market recognition, becoming an emerging production area of high-quality samples. Harvest period of Jujubae Fructus is mostly August in the past dynasties, and this is basically the same as today. The main processing method is simple cleansing and drying. Through textual research, it is suggested that Jujubae Fructus in famous classical formulas should be mainly from Shandong, Shanxi and other traditional high-quality producing areas, the processing method should follow the 2020 edition of Chinese Pharmacopoeia for simple cleansing and drying.

ABSTRACT

Through the combing of ancient books of Chinese herbal medicine in the past dynasties, a textual research of Coptidis Rhizoma involved the name, origin, medicinal parts, producing area, quality evaluation, harvesting and processing methods in famous classical formulas was conducted in this paper. After textual research, the mainstream varieties of Coptidis Rhizoma in the Ranunculaceae family before Tang and Song dynasties were Coptis chinensis and C. chinensis var. brevisepala, after the Ming and Qing dynasties, C. deltoidea, C. teeta and C. omeiensis were gradually praised. In ancient times, the authentic producing area of Coptidis Rhizoma has the characteristics of gradually moving to the west. The eastern Coptidis Rhizoma was highly praised in the early stage, while in the later stage, western Coptidis Rhizoma like chicken feet was highly praised. In the early stage, western Coptidis Rhizoma probably originated from C. chinensis and its genus, while Coptidis Rhizoma like chicken feet was cultivated, and no wild species has been found so far. As Coptidis Rhizoma has mixed use of multiple origins in ancient books of past dynasties, based on the current shortage of market resources in C. teeta and C. deltoidea, there are also endangered and protected plants of C. chinensis var. brevisepala and C. omeiensis, combined with the mainstream medicines and resources of past generations, it is recommended to choose C. chinensis as the base of the formulas. In ancient times, there were many processing methods for Coptidis Rhizoma, such as frying and wine-, ginger-, honey-processed. In the process of developing famous classical formulas, the appropriate processing specifications of Coptidis Rhizoma should be selected based on the original source records and the requirements of the medicinal material.

ABSTRACT

Based on various ancient documents such as materia medica, prescription books, classics and history, combined with relevant research materials in modern times, this paper made a textual research on the name, origin, geoherbalism, harvesting time, processing methods of Chuanxiong Rhizoma, which provides a basis for the development of famous classical formulas containing this herb. According to the textual research, the original name of Chuanxiong is Xiongqiong (芎䓖), which was first recorded in Shennong Bencaojing , there are many aliases and trade names in the past dynasties. Since the Song dynasty, doctors all take Xiongqiong produced in Sichuan as the best medicine, so they take Chuanxiong as the rectification of name. In the early stage, the origin of Chuanxiong Rhizoma was relatively complicated, and the main origin was Ligusticum chuanxiong, which was a cultivated and domesticated species of Ligusticum. However, wild related plants of Ligusticum are still used as medicine. After the Ming dynasty, new cultivated varieties appeared in various places, such as Jiangxi L. sinense cv. Fuxiong, which gradually turned to self-production and self-marketing after the Republic of China. After several changes in the authentic producing area of Chuanxiong Rhizoma, Tianshui in Gansu province was highly praised in the Tang dynasty, and Dujiangyan in Sichuan province was the best place in the Song dynasty and later dynasties. Chuanxiong Rhizoma has been widely used in the past dynasties as raw products, and it has also been processed with excipients. For example, wine-processed products can enhance the effect of promoting blood circulation, promoting Qi circulation and relieving pain. There are other processing methods such as stir-frying and vinegar processing. Chuanxiong Rhizoma in the famous classical formulas can be selected according to this research conclusion.

ABSTRACT

By consulting the ancient herbal and medical books, combined with modern literature, the name, origin, geoherbalism, harvesting and processing changes of Bambusae Caulis in Taenias in famous classical formulas were sorted out. According to the research, ancient doctors only approved three kinds of bamboo medicinal materials, namely, Jinzhu (䈽竹), Kuzhu (苦竹) and Danzhu (淡竹), and took bamboo leaves, made Bambusae Caulis in Taenias and Zhuli (竹沥) for medicine. Bamboo medicinal materials with different origins have different properties, tastes and effects, after clinical optimization, it is gradually considered that Danzhu is the best source of Bambusae Caulis in Taenias and Zhuli. According to the morphological description of the original plants and the attached drawings, it is considered that the Danzhu in ancient Chinese materia medica should be Phyllostachys nigra var. henonis, which has been included in the 2020 edition of Chinese Pharmacopoeia as one of the genuine sources of Bambusae Caulis in Taenias. Therefore, It is suggested that P. nigra var. henonis can be added as the source of Bambusae Caulis in Taenias in famous classical formulas, and the medicinal part is the dry middle layer of its stem. Ginger-processed can increase the anti emetic effect of Bambusae Caulis in Taenias, and the three formulas involving Bambusae Caulis in Taenias from The Catalogue of Ancient Famous Classical Formulas (The First Batch) all contain ginger, and the processing method of Bambusae Caulis in Taenias is not marked in the original formula, so it is suggested to use raw products in the three formulas of Jupi Zhurutang, Wendantang and Zhurutang.

ABSTRACT

In this study, name, origin, producing areas, harvesting time and processing methods of ancient Alismatis Rhizoma were systematically researched by consulting the literature of ancient herbs, medical and prescription books, so as to provide a basis for the development of famous classical formula containing this herb. According to textual research, the main base of ancient Alismatis Rhizoma was Alisma plantago-aquatica and A. orientale. A. canaliculatum and A. gramineum and other genera were sometimes used as the source of Alismatis Rhizoma, there was a confusion of medicinal varieties. The earliest producing area of Alismatis Rhizoma was in today's Henan province, and later Hanzhong, Shaanxi province, became the high-quality producing area of Alismatis Rhizoma. Since the Ming dynasty, its production area expanded to Fujian. In the Qing dynasty, Jian'ou in Fujian was the authentic production area of Alismatis Rhizoma. In the period of the Republic of China, Sichuan and Jiangxi were added to the production areas of Alismatis Rhizoma. Based on the research results, it is suggested that the dried tubers of A. orientale from Fujian and Jiangxi or A. plantago-aquatica from Sichuan should be used in the famous classical formulas. In ancient times, Alismatis Rhizoma was processed by wine, but most of the standards and specifications in modern times are no longer included the processing specifications of Alismatis Rhizoma with wine. Although salt-processed Alismatis Rhizoma is commonly used in modern times, it didn't become one of the main processing methods until the Qing dynasty. According to the relevant national documents, it is suggested that Alismatis Rhizoma without clear processing requirements in famous classical formulas should be used as raw products, and the formulas with processing requirements should be selected as processed products such as salt and wine according to the meaning of the formulas.

ABSTRACT

Through consulting the ancient herbal and medical books, combined with the field investigation, the name, origin, collection and processing of Dendrobium medicinal materials were researched, which provided a basis for the development of famous classical formulas containing this kind of herbs. Due to the wide distribution of D. officinale, the Dendrobium species represented by D. officinale and D. huoshanense, which are short, fleshy and rich in mucus, should be the most mainstream of Dendrobium medicinal materials in previous dynasties. Compared with Shihu, Muhu with loose texture, long and hollow is born on trees. According to the characteristic description, it should be D. nobile, D. fimbriatum and so on, of which D. nobile was the mainstream. The Chinese meaning of Jinchai was confused in the past dynasties, so it was not suitable to be treated as a plant name. The production areas of Dendrobium medicinal materials in the past dynasties have changed with the discovery of varieties, artificial cultivation and other factors. Lu'an, Anhui province, was the earliest recorded in the Han and Wei dynasties. Since the Tang and Song dynasties, it had been extended to Guangdong and Guangxi, and it was considered that "Dendrobii Caulis in Guangnan was the best". In the Ming dynasty, Sichuan and Zhejiang products were highly praised, and in the Qing dynasty, Huoshan products were highly praised. Dendrobium medicinal materials had been used as medicine by stems in all dynasties. The medicinal materials were divided into fresh products and dry products. The fresh products can be used immediately after removing the sediment from the roots. The dry products need further processing, most of them used wine as auxiliary materials for steaming, simmer to paste or decoction into medicine. D. officinale and D. huoshanense have special processing specifications since the middle of Qing dynasty, that is, "Fengdou". According to the research results, in Ganluyin, the effect of Dendrobium medicinal materials is mainly heat clearing, and D. nobile with bitter taste can be selected. The main effect of Dendrobium medicinal materials in Dihuang Yinzi is tonic, D. officinale or D. huoshanense can be selected.

ABSTRACT

Based on the ancient literature of all dynasties, this article makes a systematic textual research on the name, origin, producing area, quality, harvesting and processing of Zisu (Perillae) in the famous classical formulas, so as to clarify the information of the drug in different historical periods and provide a reference for the development and utilization of the related formulas. The main origin of Perillae in the ancient literature was Perilla frutescens var. frutescens (purple leaf type), followed by P. frutescens var. acuta (purple leaf type), but not Baisu. Modern chemical composition studies also show that there are obvious differences between Perillae and Baisu, which provides a scientific basis for distinguishing them. Although they are often treated as a species in plant classification, P. frutescens var. frutescens (purple leaf type) is recommended in the development of famous classical formulas, and Baisu should be avoided. Perillae is widely distributed, but its producing area did not record in most of the literature in the past dynasties, or the producing area is described as everywhere today. In the period of the Southern and Northern dynasties, the medicinal parts of Perillae included stems, leaves and seeds, and doctors in the Ming dynasty began to pay attention to the differentiation of different medicinal parts. The harvesting and processing methods of Perillae in the past dynasties are close to that of today. Perillae Fructus is mostly stir-fried and ground into medicine, Perillae Folium and Perillae Caulis are mainly simple cleansing. In production, we can refer to the 2020 edition of Chinese Pharmacopoeia.

ABSTRACT

The name, origin, place of origin, medicinal parts, harvesting and processing of lotus are verified by consulting ancient Chinese herbal medicines and medical books, combined with modern literature, providing a basis for the development of famous classical formulas containing lotus. According to textual research, the original base of lotus is Nelumbo nucifera since ancient times, rhizome (Nelumbinis Rhizomatis Nodus), leaf (Nelumbinis Folium), seed (Nelumbinis Semen), embryo (Nelumbinis Plumula), receptacle (Nelumbinis Receptaculum), stamen (Nelumbinis Stamen) and other medicinal parts of N. nucifera can be used as medicine and have different clinical effects. Nelumbinis Semen was originally produced in Henan, and then gradually expanded to Jiangnan. Today, it can be cultivated and planted throughout the country, with Fujian, Hunan, and Jiangxi as the authentic production areas. After combing the medicinal parts of N. nucifera and the historical evolution of its processing, it is suggested that the dried and mature fruits of N. nucifera taking in autumn and removing the shell and Nelumbinis Plumula should be used in Qingxin Lianziyin. Nelumbinis Folium in Erdongtang should be harvested in summer and autumn, and the raw products was used as medicine and processed in accordance with the provision of the 2020 edition of Chinese Pharmacopoeia.

ABSTRACT

OBJECTIVES@#To study the metabolic mechanism of neonatal sepsis at different stages by analyzing the metabolic pathways involving the serum metabolites with significant differences in neonates with sepsis at different time points after admission.@*METHODS@#A total of 20 neonates with sepsis who were hospitalized in the Department of Neonatology, Hunan Provincial People's Hospital, from January 1, 2019 to January 1, 2020 were enrolled as the sepsis group. Venous blood samples were collected on days 1, 4, and 7 after admission. Ten healthy neonates who underwent physical examination during the same period were enrolled as the control group. Ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry was used for the metabonomic analysis of serum samples to investigate the change in metabolomics in neonates with sepsis at different time points.@*RESULTS@#On day 1 after admission, the differentially expressed serum metabolites between the sepsis and control groups were mainly involved in the biosynthesis of terpenoid skeleton. For the sepsis group, the differentially expressed serum metabolites between days 1 and 4 after admission were mainly involved in pyruvate metabolism, and those between days 4 and 7 after admission were mainly involved in the metabolism of cysteine and methionine. The differentially expressed serum metabolites between days 1 and 7 after admission were mainly involved in ascorbic acid metabolism.@*CONCLUSIONS@#The metabolic mechanism of serum metabolites varies at different stages in neonates with sepsis and is mainly associated with terpenoid skeleton biosynthesis, pyruvate metabolism, cysteine/methionine metabolism, and ascorbic acid metabolism.
