Herbal Textual Research on Farfarae Flos in Famous Classical Formulas / 中国实验方剂学杂志

By consulting ancient and modern literature， the herbal textual research of Farfarae Flos has been conducted to verify the name， origin， producing area， quality evaluation， harvesting and processing methods， so as to provide reference for the development and utilization of the famous classical formulas containing Farfarae Flos. According to the research， the results showed that Farfarae Flos was first described as a medicinal material by the name of Kuandonghua in Shennong Bencaojing（《神农本草经》）， and the name was used and justified by later generations. The main origin was the folwer buds of Tussilago farfara， in addition， the flower buds of Petasites japonicus were used as medicine in ancient times. The ancient harvesting time of Farfarae Flos was mostly in the twelfth month of the lunar calendar， and the modern harvesting time is in December or before the ground freeze when the flower buds have not been excavated. Hebei， Gansu， Shaanxi are the authentic producing areas with the good quality products. Since modern times， its quality is summarized as big， fat， purple-red color， no pedicel is better. Processing method from soaking with licorice water in the Northern and Southern dynasties to stir-frying with honey water followed by micro-fire in the Ming dynasty， and gradually evolved to the modern mainstream processing method of honey processing. Based on the research results， it is suggested that the dried flower buds of T. farfara， a Compositae plant， should be selected for the development of famous classical formulas containing Farfarae Flos， and the corresponding processed products should be selected according to the specific processing requirements of the formulas， and raw products are recommended for medicinal use without indicating processing requirements.

Clinical characteristics and pathogen analysis of bronchoalveolar lavage fluid in elderly patients with community-acquired pneumonia.

OBJECTIVE: To analyze the clinical characteristics and bronchoalveolar lavage fluid pathogens in elderly patients with community-acquired pneumonia (CAP). METHODS: This was a retrospective observational epidemiological study using that elderly cases diagnosed with community-acquired pneumonia receiving treatment at the Affiliated Hospital of North China University of Technology, Tangshan Hongci Hospital and Tangshan Fengnan District Hospital of Traditional Chinese Medicine. A total of 92 cases were divided into two groups according to age. There were 44 patients over 75-year-old and 48 patients between 65 and 74-year-old. RESULTS: Compared with the elderly 65 to 74-year-old, the elderly over 75-year-old with diabetes are more likely to suffer from CAP (35.42% vs. 63.64%, p = 0.007) and are more likely to have mixed infections (6.25% vs. 22.73%, p = 0.023) or larger lesions (45.83% vs. 68.18%, p = 0.031). Their hospital stays will also be extended (39.58% vs. 63.64%, p = 0.020), and the albumin level (37.51 ± 8.92 vs. 30.93 ± 6.58, p = 0.000), the neutrophils level (9.09(6.26-10.63) vs. 7.18(5.35-9.17),p = 0.026) is significantly lower and the d-dimer (505.42 ± 197.12 vs. 611.82 ± 195.85, p = 0.011), PCT (0.08 ± 0.04 vs. 0.12 ± 0.07, p = 0.001) levels are significantly higher. CONCLUSION: The clinical symptoms and signs of elderly CAP patients are not so typical, and the infection is more serious. Attention should therefore be paid to elderly patients. Hypoalbuminemia and high d-dimer can predict the prognosis of patients.

Herbal Textual Research on Stephaniae Tetrandrae Radix in Famous Classical Formulas / 中国实验方剂学杂志

By reviewing ancient materia medica， medical and prescription books， combined with modern literature， the textual research of Stephaniae Tetrandrae Radix has been conducted to verify the name， origin， producing area， harvesting and processing methods. Through textual research， the results show that the mainstream name of this herb recorded in the past dynasties is Fangji， which is also called Hanzhong Fangji because it is produced in Hanzhong city， and after the Tang dynasty， it was gradually divided into Hanfangji and Mufangji， and there is the saying that Han Zhushuiqi， Mu Zhufengqi. The names of Fenfangji and Guangfangji were first seen in the republic of China. In addition， Fenfangji was once distributed in Hankou， so it was also known as "Hanfangji"， which is easily confused with the traditional Hanzhong Fangji for short. Based on the original research， it is concluded that Aristolochia heterophylla（Hanzhong Fangji）is the mainstream of Stephaniae Tetrandrae Radix used in the Qing dynasty and before， and the application history of Cocculus orbiculatus can be traced back to before the Tang dynasty. After the Ming dynasty， Stephania tetrandra gradually became another main origin， and in the Republic of China， A. fangchi was used as a medicine for Stephaniae Tetrandrae Radix， but in modern times it was banned because it contained aristolochic acid as a toxic ingredient， and S. tetrandra has become the mainstream legal origin. The traditional production area of Hanzhong Fangji is Hanzhong， Shaanxi province， while today the mainstream of S. tetrandra is manly produced in Jiangxi and other places. Based on the quality evaluation research， the quality of Hanzhong Fangji is better with the radial texture of section used as radial solution， yellow solid and fragrant. Fenfangji with solid quality， white inside， powdered enough， less fiber and radiating texture is better. From the harvesting and processing research， the root of Fangji is mostly harvested in spring and autumn， and the outer bark should be removed in some literature. Before the Ming dynasty， this herb was dried in the shade， and after the Ming dynasty， it was dried in the sun. The modern production processing of Fangji is to harvest it in autumn， wash it， remove the rough bark， dry it to half dry， cut it into sections， and then cut it longitudinally if it is large， and dry it. Based on the results， combined with current studies on the toxicity of aristolochic acid and influencing factors such as commercial circulation， it is suggested that S. tetrandra should be used as the origin of Fangji， the processed products are selected according to the prescription requirements， and those without specified requirements can be processed by referring to the raw products in the 2020 edition of Chinese Pharmacopoeia.

Research progress of histone acetylation in prevention and treatment of heart failure and new ideas based on traditional Chinese medicine / 中国中药杂志

Chronic heart failure(CHF) has become a worldwide public health problem due to its high morbidity and mortality, which seriously endangers people's lifespan and quality of life. In recent years, the treatment strategy of CHF has shifted its emphasis on short-term improvement and transformation of hemodynamics to long-term repair as well as improvement of the biological properties of heart failure. At present, with the continuous deepening of medical research, it has been found that histone acetylation is closely related to the occurrence and development of CHF. Traditional Chinese medicine, via regulating histone acetylation, delays ventricular remodeling, improves energy metabolism, inhibits fibrosis and cardiomyocyte hypertrophy, and intervenes in the development process of heart failure, thus reducing the mortality and the readmission rate and ultimately improving long-term prognosis. Therefore, this study reviewed the mechanism of histone acetylation in the treatment of heart failure as well as its prevention and treatment with traditional Chinese medicine, to provide reference for clinical treatment of CHF.

Herbal Textual Research on Trichosanthis Fructus and Trichosanthis Radix in Famous Classical Formulas / 中国实验方剂学杂志

Through reviewing the ancient and modern literature， the name， origin， producing area， quality evaluation， harvesting and processing methods of Trichosanthis Fructus（TF） and Trichosanthis Radix（TR） in famous classical formulas were systematically sorted out following the chronological order. The results showed that there were many nicknames of TF and TR， and Gualou and Tianhuafen have become the mainstream names for its fruit and root， respectively. Both of them took Trichosanthes kirilowii as the mainstream base. TF and TR have been used as medicines in the Han dynasty， and since the North and South dynasties， Leigong Paozhilun had been clear that the effects of peels， seeds， stems， roots were different. TF was used as medicine with intact fruits， harvested after maturity from September to October， hung and dried in the shade， and its quality has been summarized in recent times as being best for those who are mature， large， thick and pliable peels， orange-yellow in color， and with sufficient sugary properties. In ancient times， the processing of TR was mostly crushed or shredded with the peels and seeds， or processing for pancakes and creams. TR was used as medicine with the roots， it is harvested from November to December， peeled and dried in the sun， and its quality was best when it was deep in the soil， large， white， powdery， firm and delicate with few muscles and veins， and it was considered to be toxic when it was born in briney land. Processing method of TR was to do powder into the medicine in the Tang dynasty， and gradually evolved into direct slicing use in the Ming and Qing dynasties. Since the modern era， the authentic producing areas of TF and TR were in the vicinity of Lingbao， Henan province， known as Anyang Huafen， and in modern times， there are well-known production areas such as Anguo， which produces Qihuafen， and Jinan， which produces Changqing Gualou. In the Song dynasty， there was a habit of substituting Trichosanthis Semen for the whole herb， which was later corrected by the materia medica in Ming dynasty. Based on the results， It is suggested that T. kirilowii be selected as the basal plant for the development of famous classical formulas involving TR and TF. In Qingjin Huatantang， Trichosanthis Semen is processed by stir-frying method， while TR and TF in other five formulas from the Catalogue of Ancient Famous Classical Formulas（The First Batch） were all used in raw form.

Reduced SARS-CoV-2 infection risk is associated with the use of Seven-Flavor Herb Tea: A multi-center observational study in Shanghai, China / 中西医结合学报

OBJECTIVE@#Omicron, a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant, is responsible for numerous infections in China. This study investigates the association between the use of Seven-Flavor Herb Tea (SFHT) and the risk of SARS-CoV-2 infection to develop precise and differentiated strategies for control of the coronavirus disease 2019 (COVID-19).@*METHODS@#This case-control study was conducted at shelter hospitals and quarantine hotels in China. A total of 5348 laboratory-confirmed COVID-19 patients were enrolled between April 1 and May 31, 2022, while 2190 uninfected individuals served as healthy controls. Structured questionnaires were used to collect data on demographics, underlying diseases, vaccination status, and use of SFHT. Patients were propensity-score-matched using 1:1 nearest-neighbor matching of the logit of the propensity score. Subsequently, a conditional logistic regression model was used for data analysis.@*RESULTS@#Overall, 7538 eligible subjects were recruited, with an average age of [45.54 ± 16.94] years. The age of COVID-19 patients was significantly higher than that of uninfected individuals ([48.25 ± 17.48] years vs [38.92 ± 13.41] years; t = 22.437, P < 0.001). A total of 2190 COVID-19 cases were matched with uninfected individuals at a 1:1 ratio. The use of SFHT (odds ratio = 0.753, 95% confidence interval: 0.692, 0.820) was associated with a lower risk of SARS-CoV-2 infection compared to untreated individuals.@*CONCLUSION@#Our findings suggest that taking SFHT reduces the risk of SARS-CoV-2 infection. This is a useful study in the larger picture of COVID-19 management, but data from large-sample multi-center, randomized clinical trial are warranted to confirm the finding.

Herbal Textual Research on Anemarrhenae Rhizoma in Famous Classical Formulas / 中国实验方剂学杂志

Through reviewing ancient and modern literature， the textual research of Anemarrhenae Rhizoma（AR） has been conducted to verify the name， origin， changes in production areas， quality evaluation， harvesting and processing methods， so as to provide reference for the development and utilization of the famous classical formulas containing AR. Through the herbal textual research， AR was first published in Shennong Bencaojing， and has been used as the proper name for this herb for generations， and the mainstream source of AR used for generations is the rhizome of Anemarrhena asphodeloides. The high-quality production areas that have been revered throughout the ages are Hebei， Shanxi， Shaanxi， Inner Mongolia and Fangshan district of Beijing， etc. In recent times， AR produced in Yixian county of Hebei province（Xiling Zhimu）， is better known and is regarded as a very good source. At present， cultivated AR is mainly produced in Yixian county and Anguo of Hebei province， Bozhou of Anhui province and other places. The medicinal parts of AR in ancient and modern times are all rhizomes， and the quality is better if it has thick flesh， hard wood， yellow outer color and white section color. The harvesting time recorded in ancient medical books is usually in lunar February and August， with exposure to dryness， while modern harvesting is spring and autumn. The processing methods of the past dynasties were mainly to remove the hair when using， avoid iron when cutting， process with wine or salt water， while the two main specifications in modern times are raw and salted products. Based on the systematic research， it is recommended that the dried rhizome of A. asphodeloides in the famous classical formulas be used for AR. If the original formula specifies processing requirements， it should be operated according to the requirements， if the processing requirements are not indicated， the raw products can be used as medicine.

Herbal Textual Research on Armeniacae Semen Amarum in Famous Classical Formulas / 中国实验方剂学杂志

By consulting ancient Chinese herbal medicines and medical books， the textual research of Armeniacae Semen Amarum has been conducted to verify the name， origin， producing area， quality evaluation， harvesting and processing changes. Through textual research， Shennong Bencaojing began to contain Xinghe. After Xinxiu Bencao， Xingheren were gradually taken as the mainstream name， Xingren was first used as the correct name since Leigong Paozhilun， and gradually became the mainstream rectifying in the Ming and Qing dynasties. Before the Qing dynasty， there was no distinction between Armeniacae Semen Amarum and Armeniacae Semen Dulcis in the materia medica works， while the differences between them were clearly defined in some works of the Qing dynasty， but did not record them separately. In order to make them more accurate in clinical application， Armeniacae Semen Amarum was recorded as the correct name in the 1953 edition of Chinese Pharmacopoeia， and Armeniacae Semen Dulcis was included in the provincial standards. The original plants of Armeniacae Semen Amarum from Prunus armeniaca （Armeniaca vulgaris in Flora of China） and its cultivated varieties with bitter seeds were taken as the mainstream， which are reflected in the Chinese Pharmacopoeia. Its yellow ripe fruit was generally harvested in May， the seed kernel was taken out for drying or baking， finally the seed coat was removed to use. It is recorded that the production area of Armeniacae Semen Amarum is Taihang Mountain area of Shanxi province in ancient times. At present， its producing area is mainly concentrated in Shanxi， Shandong， Hebei and other places in north China. Historical literature pointed out that Armeniacae Semen Amarum had small toxicity， and heat treatment could reduce toxicity and increase efficiency， its main processing method was blanching and stir-frying. In addition， it is generally believed that raw products with seed coat can enhance its sweating effect since the Ming and Qing dynasties. Until now， three processed products are stipulated in the Chinese Pharmacopoeia， namely raw products， boiled and fried products. Based on textual research， it is recommended that A. vulgaris should be used as the original plant of Armeniacae Semen Amarum in famous classical formulas， and the use of processed products should follow the processing requirements marked in the formulas.

Practical value and thought on "co-regulation of body and mind" in treatment of post-stroke spasticity with acupuncture / 中国针灸

This paper reviews the application of "co-regulation of body and mind" of acupuncture for post-stroke spasticity. It is found that acupoints on the head and the back of the governor vessel, as well as Jiaji (Ex-B 2) points are mainly used for regulating the mind, and the local sites of spastic muscles and the points on the antagonistic muscles are for regulating the body specially. It is believed that regulating the mind should be integrated with regulating the body, while, the acupoint selection be associated with needling methods so as to fully achieve the "co-regulation of body and mind" and enhance the practical value of acupuncture for post-stroke spasticity. It is proposed that the classical anti-spastic needling techniques, such as huici (relaxing needling) and guanci (joint needling), should be more considered.

Efficacy of electroacupuncture for patients with dry eye syndromes: a randomized controlled trial / 针灸推拿医学（英文版）

Objective: To observe the efficacy of electroacupuncture (EA) in treating dry eye syndromes (DES) and its regulatory effects on patient's quality of life (QOL), anxiety, and depression.Methods: By following a randomized controlled study design, eligible DES patients were allocated to an EA group (EAG) or an acupuncture group (AG). Patients in the AG were intervened by acupuncture alone, while in the EAG, electrical stimulation was applied to Cuanzhu (BL2) and Taiyang (EX-HN5) in addition to the same treatment in the AG. Changes in clinical manifestations, ocular surface disease index (OSDI), Schirmer tear test-1 (STT-1), tear-film break-up time (TF-BUT), cornea fluorescein staining (CFS), and corneal sensitivity (CS) were observed, as well as changes in the short-form 36-item health survey (SF-36) and hospital anxiety and depression scale (HADS) scores. Results: The scores of clinical symptoms, OSDI, and CFS decreased significantly in both EAG and AG when compared with the baseline values (P<0.05), respectively, while the TF-BUT and CS increased significantly (P<0.05), and the tear secretion of patients in the EAG increased (P<0.05). Compared with those before treatment, the scores of physical role functioning, general health perception, emotional role functioning, and mental health of patients in both EAG and AG showed significant increases after treatment (P<0.05), together with a marked decrease in the score of anxiety (P<0.05). Compared with the AG, the EAG obtained a more significant increase in STT-1 (P<0.05).Conclusion: DES patients respond well to both EA and acupuncture treatments, manifested by prolonged TF-BUT and improvement of CS. Meanwhile, the two approaches can improve QOL and reduce anxiety. Furthermore, EA appears more effective in increasing tear secretion than acupuncture alone.

Objective: To explore the mechanism of herbal cake-partitioned moxibustion in Crohn disease (CD) treatment by observing the effect of herbal cake-partitioned moxibustion on protein expressions of colonic M2 macrophage marker CD206, AMP-activated protein kinase (AMPK) and tuberous sclerosis complex (TSC) 2. Methods: Twenty-six specific pathogen free male rats were randomly divided into a normal group, a model group and a herbal cake-partitioned moxibustion group. The CD model was prepared by enema with the mixture of 5％ (W/V) 2,4,6- trinitrobenzene sulfonic acid (TNBS) and 50％ ethanol at 2:1 (volume ratio). After the model was successfully prepared, rats in the herbal cake-partitioned moxibustion group received herbal cake-partitioned moxibustion at Qihai (CV 6) and bilateral Tianshu (ST 25). Hematoxylin-eosin (HE) staining was used to observe the histopathological changes of rat colon; immunohistochemical technique was used to detect the expression of colonic CD206 protein; Western blot, immunofluorescence, and real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) technologies were used to detect the protein and mRNA expressions of colonic AMPK and TSC2. Results: Compared with the normal group, rats in the model group showed damaged colonic mucosa, missing of the epithelial layer, thickened submucosa, vascular proliferation, massive infiltration of monocytes and lymphocytes, and cracked ulcers that reached the muscle layer. Rats in the herbal cake-partitioned moxibustion group showed reduced intestinal inflammation and healing intestinal epithelium ulcers. Compared with the normal group, rat colonic CD206 protein expression, and the protein and mRNA expressions of colonic AMPK and TSC2 were decreased in the model group (all P<0.01); compared with the model group, rat colonic CD206 protein expression was increased (P<0.01), as well as the protein and mRNA expressions of AMPK and TSC2 in the herbal cake-partitioned moxibustion (all P<0.05). Conclusion: Herbal cake-partitioned moxibustion can reduce intestinal inflammation in CD rats, increase colonic CD206 protein expression, and up-regulate the protein and mRNA expressions of colonic AMPK and TSC2.

Differences in the chemical composition of Dendrobium officinale Kimura et Migo and Dendrobium crepidatum Lindl based on UPLC-Q-TOF-MS/MS and metabolomics / 药学学报

italic>Dendrobium officinale Kimura et Migo is a rare Chinese herbal medicine, while Dendrobium crepidatum Lindl is a local medicine in Yunnan, both of which have the function of nourishing yin and stomach. To reveal the differences in chemical composition between the two species, ultra-performance liquid chromatography-quadrupole-time of flight mass spectrometry (UPLC-Q-TOF-MS/MS) was used to analyze the chemical composition of stems and leaves of D. officinale and D. crepidatum. Principal component analysis (PCA) and partial least squares discriminant analysis (OPLS-DA) were used to determine the differences in metabolites between species and parts of Dendrobium. Fifty-eight chemical compounds were identified in the two species. Analysis indicated that the side ring of alkaloids connected with nitrogen was readily cleaved during analysis. The results of PCA analysis showed that the stems and leaves of D. officinale and D. crepidatum could be easily differentiated, and the chemical constituents of D. officinale and D. crepidatum were significantly different. OPLS-DA analysis showed that there were 16 metabolite differences between the stems and 22 differences in metabolites between the leaves of D. officinale and D. crepidatum. The main metabolite differences in components between the two Dendrobium species were dendrocrepidine B, dendrocrepidine C and dendrocrepine. There were 14 differences in metabolites between the stems and leaves of D. crepidatum. In conclusion, the chemical compositions of D. officinale and D. crepidatum are quite different; the small molecular compounds of D. officinale are mainly terpenoids and flavonoids, and the content of alkaloids is low. There is no significant difference between stem and leaf. In contrast, D. crepidatum is mainly composed of alkaloids and terpenoids, with crepidamine and dendrocrepine as its unique components, and there are great differences in the components between stems and leaves. This study provides a theoretical basis for the development and utilization of Dendrobium resources.

Taking the content of four chromogens as evaluation indexes, the weight coefficients of each index were given, and the comprehensive score was calculated to optimize the extraction process. Then, prim-O-glucosylcimifugin was used as the reference, the relative calibration factors(RCFs) of cimifugin, 4'-O-β-D-glucosyl-5-O-methylvisamminol and sec-O-glucosylhamaudo to prim-O-glucosylcimifugin were calculated respectively. The contents of four components in Saposhnikoviae Radix were determined by both external standard method(ESM)and quantitative analysis of multi-components by single marker(QAMS) method, and the results were compared. At last, combined with principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA) to evaluate the quality of the Saposhnikoviae Radix in different production areas. The optimal extraction process parameter of the Saposhnikoviae Radix was as follows: liquid-to-material ratio is 60∶1(mL·g~(-1)), extraction time is 35 min, and ethanol concentration is 70%. The repeatability of the RCFs was perfect, and the results calculated by the QAMS were consistent with the results from the ESM. The stoichiometric results indicate that there are obvious differences in the distribution of Saposhnikoviae Radix in different production areas, and cimifugin and prim-O-glucosylcimifugin are the characteristic compounds that cause this difference. In this study, the optimal extraction process is stable and feasible, and the method of QAMS is accurate and reliable. From the perspective of four chromogens, there are differences in the quality of the Saposhnikoviae Radix in different production areas. Therefore, the established extraction process combined with the method of QAMS can be used to evaluate the quality of Saposhnikoviae Radix and provide a scientific basis for the quality control of Saposhnikoviae Radix.

Meta-analysis of Danhong Injection in treatment of diabetes mellitus complicated with coronary heart disease / 中国中药杂志

To systematically evaluate the clinical efficacy and safety of Danhong Injection combined with conventional therapy in improving diabetes mellitus complicated with coronary heart disease. Based on the online literature database(CNKI, Wanfang, VIP, PubMed, Web of Science, Cochran Library), the Chinese and English papers about the randomized controlled trial(RCT) of Danhong Injection in the treatment of diabetes mellitus complicated with coronary heart disease were searched comprehensively from the establishment of the databases to January 1, 2020. The papers were screened strictly according to the inclusion and exclusion criteria. Based on Jadad scale, the risk assessment of literature was carried out, and Meta-analysis was performed by STATA 12.0 software. Seventeen RCTs were included, involving 1 453 patients. The results of Meta-analysis showed that the combination of Danhong Injection and conventio-nal treatment could improve the clinical comprehensive effective rate(RR=1.47, 95%CI[1.38, 1.58], P<0.000 1), electrocardiogram(ECG) efficiency(RR=1.30, 95%CI[1.16, 1.46], P<0.000 1), efficiency of the angina pectoris(RR=1.41, 95%CI[1.25, 1.58], P<0.000 1), cholesterol level(SMD=-1.05, 95%CI[-1.95,-0.16], P=0.02), low-density lipoprotein(LDL) level(SMD=-0.50, 95%CI[-0.79,-0.21], P<0.000 1), coronary angina attack frequency(SMD=-3.71, 95%CI[-4.05,-3.36], P<0.000 1) and duration of angina pectoris(SMD=-2.96, 95%CI[-3.25,-2.66], P<0.000 1), with statistically significant differences. But the differences in fasting plasma glucose(FPG)(SMD=-0.19, 95%CI[-0.45, 0.08], P=0.16), plasma glucose of two hours after meal(2 hPG)(SMD=0.19, 95%CI[-0.11, 0.49], P=0.22), and high-density lipoprotein(HDL) level(SMD=0.10, 95%CI[-0.30, 0.49], P=0.62) after treatment were not statistically significant. Compared with the control group, there was no significant difference in adverse reactions(SMD=-2.96, 95%CI[-3.25,-2.66], P=0.75). The existing evidence shows that the combination of Western medicine and Danhong Injection can improve the clinical effect for diabetes mellitus complicated with coronary heart disease and has no obvious adverse reactions. However, due to the low level of overall literature evidence, high risk and some kind of publication bias, it still needs more high-quality randomized controlled trials and low-bias studies for further verification.

Technical specification for Instructions for Clinical Application of Chinese Patent Medicines in China Association of Chinese Medicine / 中国中药杂志

In order to solve the problems of confusion in clinical medication and imperfect instructions in Chinese patent medicines(CPMs), the Standardization Department of the China Association of Chinese Medicine and Center for Pharmacovigilance and Rational use of Chinese Medicine in Beijing University of Chinese Medicine jointly compiled the Instructions for Clinical Application of Chinese Patent Medicines(CPMs). As the interpretation and supplement of drug instruction information, it aims to guide clinical safety and rational use of CPMs. In addition, the technical specification for clinical application description of CPMs has been formulated, which covers the seven processes of "carding instructions, clinical investigation, data retrieval, data screening, evidence classification, path transformation and writing format". It will enable readers of Instructions for Clinical Application of Chinese Patent Medicines to understand the work behind the compilation.
