Exploration and example interpretation of real-world herbal prescription classification based on similarity matching algorithm / 中国中药杂志

In observational studies, herbal prescriptions are usually studied in the form of "similar prescriptions". At present, the classification of prescriptions is mainly based on clinical experience judgment, but there are some problems in manual judgment, such as lack of unified criteria, labor consumption, and difficulty in verification. In the construction of a database of integrated traditional Chinese and western medicine for the treatment of coronavirus disease 2019(COVID-19), our research group tried to classify real-world herbal prescriptions using a similarity matching algorithm. The main steps include 78 target prescriptions are determined in advance; four levels of importance labeling shall be carried out for the drugs of each target prescription; the combination, format conversion, and standardization of drug names of the prescriptions to be identified in the herbal medicine database; calculate the similarity between the prescriptions to be identified and each target prescription one by one; prescription discrimination is performed based on the preset criteria; remove the name of the prescriptions with "large prescriptions cover the small". Through the similarity matching algorithm, 87.49% of the real prescriptions in the herbal medicine database of this study can be identified, which preliminarily proves that this method can complete the classification of herbal prescriptions. However, this method does not consider the influence of herbal dosage on the results, and there is no recognized standard for the weight of drug importance and criteria, so there are some limitations, which need to be further explored and improved in future research.

Efficacy and safety of Regan Syrup in treatment of common cold (wind-heat syndrome):a multicenter, randomized, double-blind, double-dummy, placebo and positive drug-controlled, parallel, phase Ⅱb clinical trial / 中国中药杂志

Regan Syrup has the effect of clearing heat, releasing exterior, benefiting pharynx and relieving cough, and previous phase Ⅱ clinical trial showed that the efficacy of Regan Syrup high-dose and low-dose groups was better than that of the placebo group, and there was no statistically significant difference in the safety between the three groups. The present study was conducted to further investigate the efficacy and safety of the recommended dose(20 mL) of Regan Syrup in the treatment of common cold(wind-heat syndrome). Patients who met the inclusion and exclusion criteria were selected and divided into the test group(Regan Syrup+Shufeng Jiedu Capsules placebo), positive drug group(Regan Syrup placebo+Shufeng Jiedu Capsules) and placebo group(Regan Syrup placebo+Shufeng Jiedu Capsules placebo) at a 1∶1∶1 using a block randomization method. The course of treatment was 3 days. A total of 119 subjects were included from six study centers, 39 in the test group, 40 in the positive drug group and 40 in the placebo group. The onset time of antipyretic effect was shorter in the test group than in the placebo group(P≤0.01) and the positive drug group, but the difference between the test group and the positive drug group was not significant. The test group was superior to the positive drug group in terms of fever resolution(P<0.05), and had a shorter onset time of fever resolution than the placebo group, but without obvious difference between the two groups. Compared to the positive drug group, the test group had shortened disappearance time of all symptoms(P≤0.000 1). In addition, the test group was better than the positive drug group and the placebo group in relieving symptoms of sore throat and fever(P<0.05), and in terms of clinical efficacy, the recovery rate of common cold(wind-heat syndrome) was improved in the test group compared to that in the placebo group(P<0.05). On the fourth day after treatment, the total TCM syndrome score in both test group and positive drug group was lower than that in the placebo group(P<0.05). There was no significant difference in the incidence of adverse events between three groups and none of them experienced any serious adverse events related to the study drug. The results indicated that Regan Syrup could shorten the onset time of antipyretic effect, reduce the time of fever resolution, alleviate the symptoms such as sore throat and fever caused by wind-heat cold, reduce the total score of Chinese medicine symptoms, and improve the clinical recovery rate with good safety.

Application and significance of mixed methods research in traditional Chinese medicine and narrative medicine / 中国中药杂志

Since narrative medicine was introduced in China, it has been widely used in medical education and clinical practice. The research on narrative medicine in China is especially characterized by its combination with traditional Chinese medicine(TCM). At present, the research on narrative medicine in China is still in the stage of small-scale practicing and theory advocating. Besides, there is also a lack of guidance on experimental design methodology for clinical application, which leads to few high-quality studies in this field. The present study reviewed the current high-quality research on narrative medicine to discuss the value and prospects of mixed methods research in narrative medicine. In addition, the common design, application procedures, and notes of mixed methods research were explained to provide references for the extensive applications of narrative medicine in the medical field, especially TCM clinical practice, education, and scientific research.

Thoughts on path of R&D and registration of innovative traditional Chinese medicine with synchronous transformation of "series prescriptions" / 中国中药杂志

Since the implementation of drug registration in China, the classification of Chinese medicine has greatly met the needs of public health and effectively guided the transformation, inheritance, and innovation of research achievements on traditional Chinese medicine(TCM). In the past 30 years, the development of new Chinese medicine has followed the registration transformation model of " one prescription for single drug". This model refers to the R&D and registration system of modern drugs, and approximates to the " law-abiding" medication method in TCM clinic, while it rarely reflects the sequential therapy of syndrome differentiation and comprehensive treatment with multiple measures. In 2017, Opinions on Deepening the Reform of Review and Approval System and Encouraging the Innovation of Drugs and Medical Devices released by the General Office of the CPC Central Committee and the General Office of the State Council pointed out that it is necessary to " establish and improve the registration and technical evaluation system in line with the characteristics of Chinese medicine, and handle the relationship between the traditional advantages of Chinese medicine and the requirements of modern drug research". Therefore, based on the development law and characteristics of TCM, clinical thinking should be highlighted in the current technical requirements and registration system of research and development of Chinese medicine. Based on the current situation of registration supervision of Chinese medicine and the modern drug research in China, the present study analyzed limitations and deficiency of " one prescription for single drug" in the research and development of Chinese medicine. Additionally, a new type of " series prescriptions" was proposed, which was consistent with clinical thinking and clinical reality. This study is expected to contribute to the independent innovation and high-quality development of the TCM industry.

Thinking and practice of key links in design of clinical trial scheme for treatment of influenza with traditional Chinese medicine / 中国中药杂志

To sort out the key points in "PICOS" design of clinical trial scheme for influenza, and optimize the clinical trial scheme of Chinese patent medicine in the treatment of influenza by strictly following the principle of evidence-based medicine, focusing on the clinical practice of the disease, and highlighting the characteristics of traditional Chinese medicine. "The design of a randomized, double-blind, positive parallel control study of a certain herbal preparation for the treatment of non-severe influenza" was taken as an example in this study, and the key points in the clinical trial design of Chinese patent medicine for the treatment of influenza were specifically discussed from six aspects, including the type of study, object of study, intervention measures, control measures, outcome indicators and frequently asked questions in test design. From methodological suggestions, in the design scheme of clinical trial on efficacy and safety of Chinese patent medicine in the treatment of influenza, the randomized controlled study should be the first choice for type of study; the inclusion criteria should define both the diagnostic criteria of Western medicine and the syndromes of traditional Chinese medicine(TCM); the exclusion criteria should include a comprehensive list of confounding factors and special circumstances lea-ding to bias in the study results; the interventions should be based on a well-defined dosing programme; internationally recognized positive drugs or guidelines should be used as control measures, with median antipyretic time as the main outcome indicator. For the evalua-tion of curative effect, disease symptom scale can be set, and the TCM syndrome scoring scale was carefully used in this study, with time nodes set for the efficacy evaluation standard. The full name of the drugs should be written in the regulations on combined drug use and prohibited drug use.

Mechanism of Xuanfei Baidu Tang in treatment of COVID-19 based on network pharmacology / 中国中药杂志

The study aimed to investigate the multi-constituent, multi-target mechanism of Xuanfei Baidu Tang(XFBD) in the treatment of coronavirus disease 2019(COVID-19), through exploring the main ingredients and effective targets of XFBD, as well as analyzing the correlation between XFBD targets and COVID-19. The compounds of each herb in XFBD were collected from TCM-PTD, ETCM, TCMSP and SymMap database. Next, the information of meridian tropisms was collected from Chinese Pharmacopoeia(2015 edition), and the target information of the major constituents of XFBD were obtained from TCM-PTD, ETCM, TCMSP and TargetNet database. Subsequently, the target network model and the major modules were generated by Cytoscape, and the functional enrichment analysis of XFBD targets were completed by DAVID and STRING. As a result, ten of the 13 herbs in XFBD belonged to the lung meridian, and 326 of the 1 224 putative XFBD targets were associated with the disease target of COVID-19, among which 109 targets were enriched in the disease pathways of viral infection and lung injury. The main biological pathways regulated by the key XFBD targets included viral infection, energy metabolism, immunity and inflammation, parasites and bacterial infections. In conclusion, the therapeutic mechanism of XFBD in COVID-19 showed a multi-herb, multi-constituent, multi-target pattern, with lung as the chief targeted organ. By regulating a series of biological pathways closely related to the occurrence and development of diseases, XFBD plays a role in balancing immunity, eliminating inflammation, regulating hepatic and biliary metabolism and recovering energy metabolism balance.

Furthermore, in order to promote the Guideline more clearly, we should strengthen the doctor-patient education, improve guidance quality and increase the publicity, providing basis for the implementation and promotion strategies of the Guideline.

Interpretation and prospect of clinical practice guideline on traditional Chinese medicine therapy alone or combined with antibiotics for sepsis / 中国中药杂志

Clinical practice guideline on traditional Chinese medicine therapy alone or combined with antibiotics for sepsis is strictly in accordance with the latest diagnostic criteria for sepsis (sepsis-3) for the treatment of septic patients at different stages through syndrome differentiation. At present, the abuse of antibiotics and the prevalence of drug-resistant bacteria are very serious, without effective solutions. Thus, this is the first time to focus on traditional Chinese medicine combined with antibiotics to treat sepsis, in order to minimize the incidence of drug-resistant bacteria. This Guideline tends to systematically analyze the sepsis period, septic shock period as well as different clinical symptoms and traditional Chinese medicine measures for organ dysfunction in the sepsis process. By analyzing and interpreting the Guideline systematically, the clinicians could understand its purpose, significance and core ideas more thoroughly, and grasp the recommended specific interventions as well as their advantages and disadvantages, hoping to better implement the Guideline, provide guidance to clinicians and standardize the treatment of sepsis by traditional Chinese medicine.

Spinal gastrin-releasing peptide system mediates sexual function of males: advances in studies / 中华男科学杂志

A collection of neurons in the upper lumbar spinal cord (lumbar segments 3 and 4) of male rats project to the lower lumbar spinal cord (lumbar segments 5 and 6) and release a gastrin-releasing peptide (GRP) to the somatic and autonomic regions, which are known to regulate male sexual reflexes. The GRP plays some special functions when bound to the specific GRP receptor (GRPR). The spinal GRP system is regulated by androgens. Accumulating evidence shows that GRP plays an important role in rat penile erection and ejaculation, and pharmacological stimulation of GRPRs with a specific agonist can restore penile reflexes and ejaculation in castrated male rats. Therefore, the GRP system appears to be a potential therapeutic target for the treatment of erectile dysfunction or ejaculatory dysfunction. The present paper briefly reviews the recent studies on the role of the spinal GRP system in regulating the sexual function of males.
