ObjectiveIn order to provide a reference for the optimization of preparation process of stir-fried Glycyrrhizae Radix et Rhizoma(sf-GRR), the quality changes during the processing was studied. MethodsGlycyrrhizae Radix et Rhizoma was processed by stir-frying for 17 min, and samples were collected every 1 min during the processing. The appearance color of the samples was determined by visual analysis technology, the moisture and extract of the process samples were detected by the drying method and the hot extraction method of alcohol-soluble extract in the general rules of the 2020 edition of Chinese Pharmacopoeia(part Ⅳ), and the contents of liquiritin apioside, liquiritin, isoliquiritin apioside, isoliquiritin, licoricesaponin G2 and glycyrrhizic acid in the process samples were determined by high performance liquid chromatography(HPLC). Then principal component analysis(PCA), partial least squares-discriminant analysis(PLS-DA) and Spearman correlation analysis were used for clustering, discrimination and correlation analysis of the appearance color, moisture, extract and the contents of six internal components. Based on artificial neural network and random forest algorithm, the prediction model of processing degree of sf-GRR was established. On this basis, based on the five principles of quality marker(Q-Maker), explore the monitoring Q-Maker of sf-GRR. ResultsThe color of Glycyrrhizae Radix et Rhizoma deepened after stir-frying, and the appearance color of the sample changed from light yellow to dark yellow during processing. During the stir-frying process, the moisture content showed a decreasing trend with the extension of processing time, while the extract content showed an increasing trend with the extension of processing time. After stir-frying, the contents of liquiritin apioside, liquiritin and licoricesaponin G2 showed an overall decreasing trend, while the contents of isoliquiritin apioside and isoliquiritin increased, and the content of glycyrrhizic acid increased slightly. The correlation analysis showed that moisture was positively correlated with brightness(L*) and red/green value(a*), and negatively correlated with yellow/blue value(b*) and total color difference(E*ab). Isoliquiritin apioside and isoliquiritin had negative correlation with L* and a*, and positive correlation with b* and E*ab. The processing process of sf-GRR could be divided into two stages of the early stage(0-14 min) and the late stage(15-17 min), and could be divided into three stages of the early stage(0-6 min), the middle stage(7-14 min) and the late stage(15-17 min) by combining the moisture, extract, the contents of 6 components and color values. Based on artificial neural network analysis and random forest algorithm, isoliquiritin apioside, isoliquiritin, liquiritin and glycyrrhizic acid were selected as monitoring markers for sf-GRR. ConclusionBased on the analysis of the exterior-interior indicators of process samples of sf-GRR, this paper ultimately identifies four processing monitoring markers, which can provide a basis for optimizing the processing technology of sf-GRR.

Didangtang is a classic formula for treating blood stasis and heat, as recorded in the Treatise on Febrile Diseases, and it has been highly praised by medical practitioners throughout history. It has been recorded in many traditional Chinese medical texts and used to this day. This article comprehensively examined the records of Didangtang in different ancient versions of Treatise on Febrile Diseases by excavating and sorting out related ancient medical books and modern literature. It also investigated the dosage unit measurement, preparation method, and content of the formula in medical books throughout history. The article provided a detailed summary and exploration of the origins and processing methods of rhubarb, peach kernels, leeches, and flies in the formula. At the same time, it reviewed the clinical practice of Didangtang by medical practitioners throughout history in relevant medical books, mainly including the adjustment of dosage forms, the increase or decrease in medicinal taste and dosage, the expansion of clinical application, and the creation and elucidation of similar formulas. Although there may be differences in the above information among medical practitioners throughout history, the basic idea of attacking blood stasis and heat is consistent. In addition, based on clinical practice, the author adhered to the principle of treating stasis and heat disease as the first reference when using Didangtang. It was suggested that blood should be circulated instead of stopping in the treatment of stasis and heat accumulation syndrome. At the same time, it was believed that the use of the method of attacking stasis and heat to regulate brain diseases and mental illnesses derives from the fact that removing stasis and generating new energy can nourish the heart and mind, providing ideas for the treatment of such diseases with Didangtang. On this basis, modern clinical and animal experiments have shown that Didangtang has certain effects in improving microcirculation disorders, regulating blood rheology and hemodynamics, enhancing insulin resistance, and inhibiting inflammatory reactions. This may be an important mechanism for the formula to ''conquer blood stasis and heat''. This article explored the textual research and clinical mechanism of Didangtang, presenting facts and evidence, so as to provide a reference for the clinical application of Didangtang and the research on other prescriptions.

OBJECTIVE To provide reference for improving the pre-prescription review system and reducing the occurrence of medication error by analyzing the drug-related problems (DRPs) in the pre-prescription review orders of pediatric outpatient clinics using the Pharmaceutical Care Network Europe (PCNE) classification system. METHODS The data of pre-prescription review orders were retrospectively collected from outpatient department of Shanghai Children’s Medical Center, Shanghai Jiao Tong University School of Medicine from July 2022 to June 2023; DRPs in the pre-prescription review orders were classified and summarized by using the PCNE classification system (version 9.1), and then analyzed in terms of types and causes of issues, and the acceptance of interventions. RESULTS A total of 66 017 DRPs orders were included, involving 41 165 patients. The proportion of DRPs orders in children aged ≤5 years old was the highest (58.25%), followed by children aged 6-12 years old (33.52%); the department with the highest proportion of DRPs was internal medicine of pediatrics department (71.41%); the department with the highest incidence of DRPs was thoracic surgery department (9.73%); top three drug categories of DRPs orders were systemic anti- infective drugs (25.26%), Chinese patent medicines (24.74%) and respiratory drugs (22.38%). Referring to PCNE classification system, the types of DRPs mainly focused on treatment safety (64.86%); the reasons of DRPs orders mainly focused on dose selection (82.09%), of which 41.26% were due to excessive drug dosage; 92.13% of interventions could be accepted and fully executed by doctors. CONCLUSIONS DRPs orders identified by the pre-prescription review system can be effectively analyzed by using PCNE classification system. Pharmacists should focus on medication use in children aged ≤5 years old, update and develop personalized prescription review rules timely, and meet the rational needs of clinical medication for children.

Jianghuanglian is one of the representative processed products of Coptidis Rhizoma for treating cold syndrome with drugs of heat nature, and ginger is used to restrict the bitter cold of Coptidis Rhizoma, which can be traced back to Bojifang, and it is suitable for stagnation of damp-heat in middle-jiao, cold-heat mutual knots and other symptoms. Jianghuanglian retains the alkaloids, phenylpropanoids and flavonoids of Coptidis Rhizoma, and also introduces gingerol components such as 6-gingerol in ginger, which has pharmacological activities such as anti-inflammatory, antibacterial, anti-tumor, and improving gastrointestinal function. The 2020 edition of Chinese Pharmacopoeia and many local processing specifications have included the traditional processing process and quality standards of Jianghuanglian, but the specific process parameters and quality standards are incomplete, which limits the production and clinical application of this processed product. By summarizing the processing history, process research, quality evaluation, pharmacodynamic and medicinal property changes and application of Jianghuanglian in the past 20 years, there are differences in the processing methods and standards in various provinces and cities, which are mainly reflected in the preparation method, dosage, processing process and quantitative standards of ginger juice. In addition, there are also certain differences in the changes of the main components of Jianghuanglian prepared from ginger or dried ginger, as well as their efficacy and medicinal properties. The research on the processing process of Jianghuanglian plays an important role in improving its quality standards, and this review can provide a reference for improving the quality evaluation system of Jianghuanglian.

“Runner’s high” refers to a momentary sense of pleasure that suddenly appears during running or other exercise activities, characterized by anti-anxiety, pain relief, and other symptoms. The neurobiological mechanism of “runner’s high” is unclear. This review summarizes human and animal models for studying “runner’s high”, analyzes the neurotransmitters and neural circuits involved in runner’s high, and elucidates the evidence and shortcomings of researches related to “runner’s high”. This review also provides prospects for future research. Research has found that exercise lasting more than 30 min and with an intensity exceeding 70% of the maximum heart rate can reach a “runner’s high”. Human experiments on “runner’s high” mostly use treadmill exercise intervention, and evaluate it through questionnaire surveys, measurement of plasma AEA, miRNA and other indicators. Animal experiments often use voluntary wheel running intervention, and evaluate it through behavioral experiments such as conditional place preference, light dark box experiments (anxiety), hot plate experiments (pain sensitivity), and measurement of plasma AEA and other indicators. Dopamine, endogenous opioid peptides, endogenous cannabinoids, brain-derived neurotrophic factor, and other substances increase after exercise, which may be related to the “runner’s high”. However, attention should be paid to the functional differences of these substances in the central and peripheral regions, as well as in different brain regions. Moreover, current studies have not identified the targets of the neurotransmitters or neural factors mentioned above, and further in-depth researches are needed. The mesolimbic dopamine system, prefrontal cortex-nucleus accumbens projection, ventral hippocampus-nucleus accumbens projection, red nucleus-ventral tegmental area projection, cerebellar-ventral tegmental area projection, and brain-gut axis may be involved in the regulation of runner’s high, but there is a lack of direct evidence to prove their involvement. There are still many issues that need to be addressed in the research on the neurobiological mechanisms of “runner’s high”. (1) Most studies on “runner’s high” involve one-time exercise, and the characteristics of changes in “runner’s high” during long-term exercise still need to be explored. (2) The using of scales to evaluate subjects lead to the lacking of objective indicators. However, some potential biomarkers (such as endocannabinoids) have inconsistent characteristics of changes after one-time and long-term exercise. (3) The neurotransmitters involved in the formation of the “runner’s high” all increase in the peripheral and/or central nervous system after exercise. Attention should be paid to whether peripheral substances can enter the blood-brain barrier and the binding effects of neurotransmitters to different receptors are completely different in different brain regions. (4) Most of the current evidence show that some brain regions are activated after exercise. Is there a functional circuit mediating “runner’s high” between these brain regions? (5) Although training at a specific exercise intensity can lead to “runner’s high”, most runners have not experienced “runner’s high”. Can more scientific training methods or technological means be used to make it easier for people to experience the “runner’s high” and thus be more willing to engage in exercise? (6) The “runner’s high” and “addiction” behaviors are extremely similar, and there are evidences that exercise can reverse addictive behaviors. However, why is there still a considerable number of people in the sports population and even athletes who smoke or use addictive drugs instead of pursuing the “pleasure” brought by exercise? Solving the problems above is of great significance for enhancing the desire of exercise, improving the clinical application of neurological and psychiatric diseases through exercise, and enhancing the overall physical fitness of the population.

Type 2 diabetes mellitus (T2DM) and hypertension are common and frequent chronic non-communicable diseases, which often coexist in clinical practice, resulting in a large number of cardiovascular events and deaths, and their case fatality rate far exceeds that of other factors such as dyslipidemia and obesity. Based on the diagnostic standards, guidelines, and animal model evaluation methods of T2DM with hypertension at home and abroad, this study summarized, evaluated, and analyzed the characteristics of the existing animal models of T2DM with hypertension based on the clinical symptoms in traditional Chinese and Western medicine. The animal models showing high fitting degrees with the clinical symptoms in Western medicine are mainly established by injection of streptozocin (STZ) in SHR rats in the surgical induction and chemical induction methods and feeding a high-fat and high-salt diet combined with STZ injection in SD rats in the dietary induction methods. The models showcasing high fitting degrees with the clinical symptoms in traditional Chinese medicine (TCM) are mainly established by the surgical induction method. Considering the fitting degrees and the advantages and disadvantages, the ideal modeling method for T2DM with hypertension is the two-kidney, one clip (2K1C) method (a surgical induction method) combined with feeding a high-fat and high-sugar diet and STZ injection. However, the available models lack the characteristics of TCM and the evaluation indicators have poor specificity. This study found that there are few animal models of T2DM with hypertension considering the characteristics of both disease and syndrome, which may be related to the identification and attribution of TCM syndromes in animal macroscopic information. In view of this problem, it is suggested that the evaluation criteria should be established and improved for the animal models combining disease and syndrome, which can help to evaluate the fitting degree of the pathological characteristics of different syndromes in the animal models of T2DM with hypertension. In this way, ideal animal models of T2DM with hypertension can be established to simulate the disease occurrence and development in the human body. The animal models are expected to provide an ideal approach for the further research on the pathogenesis of T2DM and its prevention and treatment with TCM, which is of great significance for the treatment and prevention of T2DM with hypertension and the prognosis of its complications. At the same time, breakthroughs in the basic syndrome models of comorbidities are expected to lay a foundation for the leapfrog development of TCM research.
