ObjectiveTo analyze the research situation, hotspots, and trend of the compatibility of bitter and pungent medicinals in traditional Chinese medicine by knowledge mapping and provide reference for the inheritance and clinical application of this theory. MethodsThe literature on the compatibility of bitter and pungent medicinals was retrieved from 6 databases, including China National Knowledge Infrastructure (CNKI), VIP, Wanfang Data, SinoMed, Web of Science, and PubMed. The literature was searched with the keywords of bitter medicinals, pungent medicinals, compatibility, Banxia Xiexin decoction, Zhuyu pills, and Zuojin pills. The search time ranged from January 1, 1984 to August 10, 2024. NoteExpress 3.7 was used for literature screening, and CiteSpace 6.1.R2 was used to visualize the number of publications, authors, institutional cooperation network, and the co-occurrence, clustering, time line, and burst of keywords. ResultsA total of 628 Chinese articles and 151 English articles related to the compatibility of bitter and pungent medicinals were included, and the annual number of publications rose with fluctuations. WEI Wei was the core author of Chinses articles and SHEN Tao and ZHAO Yanling were the core authors of English articles. China Academy of Chinese Medical Sciences formed a close cooperative network with many research institutions at home and abroad. The high-frequency keywords included pungent dispersing and bitter descending, Coptidis Rhizoma, Euodiae Fructus, Banxia Xiexin decoction, Zuojin pills, compatibility, spleen and stomach diseases, and gut microbiota, which mainly involved common prescriptions, diseases responding specifically to traditional Chinese medicine, mechanism research and so on. The keyword bursts concentrated in famous doctors' experience, network Meta-analysis, inflammatory bowel disease, diabetes mellitus, intestinal microbiota, etc. The compatibility of bitter medicinals and pungent medicinals was widely used in clinical practice. Based on pungent dispersing and bitter descending, the middle energizer was regulated for treating spleen and stomach diseases and inflammatory bowel disease. Bitter and pungent medicinals descending the turbid were used to treat diabetes mellitus and hyperlipidemia by lowering blood glucose and lipid levels. The mild bitter and slightly pungent medicinals were used as supplements to treat depression and COVID-19 by regulating Qi movement. ConclusionIn the past 40 years, the number of publications on the compatibility of bitter and pungent medicinals has been increasing, and the research team has begun to take form. Clinically, the compatibility of bitter and pungent medicinals is the main treatment for spleen and stomach diseases and glycolipid metabolic diseases. At present, the modern scientific essence of the compatibility of bitter and pungent medicinals is mainly explained based on famous doctors' experience inheritance, network meta-analysis, and intestinal flora.

ObjectiveTo observe the efficacy and safety of Zhuyuwan in the treatment of hyperlipidemia (syndrome of phlegm turbidity and obstruction) complicated with carotid atherosclerosis. MethodsA total of 120 patients with hyperlipidemia (syndrome of phlegm turbidity and obstruction) complicated with carotid atherosclerosis were randomly allocated into a treatment group and a control group, with 60 patients in each group. The control group orally took rosuvastatin calcium tablets, 10 mg each time, once a day. The treatment group took Zhuyuwan granules, 1 dose a day in 3 times. Both groups received diet and exercise guidance and were treated for 24 consecutive weeks. The traditional Chinese medicine (TCM) symptom scores were recorded before and after treatment. The levels of blood lipids [total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C)], carotid color ultrasound [carotid intima-media thickness (IMT), plaque number, maximum plaque area, and maximum plaque thickness], vascular intimal repair-related factors [nitric oxide (NO), endothelin-1 (ET-1), soluble intercellular adhesion molecule 1 (sICAM-1), and thromboxane B2 (TXB2)], and oxidative stress-related indicators [superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px)] were measured before and after treatment. The occurrence of adverse reactions was observed during treatment, and the clinical efficacy of the two groups was compared after treatment. ResultsThe trial was completed and 112 patients (57 in the treatment group and 55 in the control group) were included in the statistical analysis, and the general information of the two groups was comparable. The total response rate in the treatment group was 87.72% (50/57), which was higher than that (74.55%, 41/55) in the control group (χ2=4.823, P<0.05). After treatment, the scores of main TCM symptoms such as body obesity, chest tightness, and limb numbness, the scores of secondary symptoms such as palpitation, insomnia, tastelessness in the mouth, reduced appetite, tongue and pulse manifestation scores, and the total TCM symptom score decreased in both groups (P<0.05, P<0.01). Moreover, the treatment group had lower scores of main symptoms such as body obesity, head heaviness, chest tightness, nausea, salivation, and limb numbness, scores of secondary symptoms such as tastelessness in the mouth and reduced appetite, and total TCM symptom score than the control group (P<0.05, P<0.01). After treatment, both groups showed declines in TC, TG, LDL-C, IMT, plaque number, maximum plaque area, maximum plaque thickness, ET-1, sICAM-1, and TXB2 (P<0.05, P<0.01) and elevations in levels of HDL-C, NO, and SOD (P<0.05, P<0.01). The treatment group had lower TC, TG, LDL-C, IMT, plaque number, maximum plaque area, maximum plaque thickness, ET-1, sICAM-1, and TXB2 (P<0.01) and higher levels of HDL-C, NO, SOD, and GSH-Px (P<0.05, P<0.01) than the control group. During treatment, adverse reactions occurred in 3 cases (5.26%, 1 case of dizziness, 1 case of acid reflux, and 1 case of constipation) in the treatment group and 4 cases (7.27%, 2 cases of upper respiratory tract infection, 1 case of abdominal pain, and 1 case of low back pain) in the control group. ConclusionZhuyuwan can effectively reduce blood lipid levels, inhibit the formation of carotid atherosclerotic plaque, and alleviate the syndrome of phlegm turbidity and obstruction by promoting vascular intima repair and improving the antioxidant function.

This article discusses the key pathogenesis of atherosclerosis (AS) based on the physiological characteristics and pathological changes of lipids and introduces the therapeutic effect of Zhuyuwan on AS, aiming to provide a theoretical basis for the treatment of cardiovascular diseases from the spleen. As essential substances, lipids have the same essence but different forms. They circulate throughout the body with body fluids under the action of Yang Qi to nourish the nutrient Qi and support the defensive Qi. Lipid metabolism disorder often leads to the obstruction of Qi movement, the accumulation of dampness and turbidity, and the generation of phlegm and blood stasis. It has been proven that the formation of vulnerable plaques in AS is attributed to the interaction of three pathogenic factors: deficiency of healthy Qi, phlegm-turbidity, and collateral stasis. Their pathological essence is closely related to abnormal lipid metabolism. As lipids constitute the thick and dense components of body fluids, their impaired dispersion may lead to phlegm-turbidity and blood stasis, the pathological process of which is predominantly ascribed to the dysfunction of the spleen in distributing essence. Therefore, AS is rooted in spleen-stomach disorder, manifests as plaques formed by pathological product accumulation in vessels, with lipid transport disorder as its core pathogenesis. Specifically speaking, the dysfunction of spleen in transportation with accumulation of dampness-turbidity marks the initial stage, and blood turbidity and coagulation and phlegm-nodules accumulating in vessels represent the intermediate phase. Cold accumulation and stagnated heat transforming into toxins represent the terminal stage. Zhuyuwan, first recorded in Taiping Holy Prescriptions for Universal Relief, contains equal proportions of Coptidis Rhizoma and Evodiae Fructus. Coptidis Rhizoma, bitter and cold, exerts descending and purging actions to assist stomach Qi in lowering turbidity. Evodiae Fructus, pungent-bitter and hot, disperses obstruction and promotes free flow to support spleen Qi in ascending the clear. The compatibility of Coptidis Rhizoma and Evodiae Fructus ascends the clear and descends the turbid to harmonize Yin and Yang, assisting the spleen in distributing essence and resolving lipid accumulation to reduce lipid levels. In terms of the therapeutic mechanism, Zhuyuwan modulates lipid metabolism by correcting immune-inflammation network imbalance, improving gut microbiota composition and metabolism, and enhancing reverse cholesterol transport. By analyzing the pathological characteristics of lipid transport disorder in AS, this study delves into the intrinsic connections between cardiovascular disease and lipid transport disorder, giving novel insights into the prevention and treatment of AS.

ObjectiveTo investigate the alleviating effect of calcium cyanamide (CaCN2) soil fumigation on replanting problems of Rehmannia glutinosa. MethodsNewly soil (NP) was used as the control group, while three treatment groups were established: replanted soil (RP), newly soil treated with CaCN2 (120 g·m², tillage depth 25 cm) (NPCC), and replanted soil treated with CaCN2 (RPCC). R. glutinosa was cultivated in all groups. At harvest, the tuber agronomic traits (number of enlarged roots, maximum root diameter, fresh weight, dry weight) were measured. The content of catalpol and rehmannioside D was quantified by ultra-high-performance liquid chromatography (UPLC) to evaluate medicinal quality. Rhizosphere soil available nutrients and enzyme activities were analyzed by assay kits. The community structure and composition of fungi and bacteria in rhizosphere soil were assessed via internal transcribed spacer 2 (ITS2) sequencing and 16S rDNA sequencing, respectively. ResultsCompared with NP, the RP group showed obviously reduced in tuber agronomic traits and quality indicators (P0.05). However, the RPCC group showed significant improvement in agronomic traits and a notable increase in rehmannioside D content compared to RP (P0.05). The contents of available phosphorus and potassium in RPCC and NP groups were obviously lower than those in RP (P0.05). The polyphenol oxidase soil (S-PPO) activity in RP was obviously lower than in NP (P0.05), while sucrose soil (S-SC), acid phosphatase soil (S-ACP), and S-PPO activities in RPCC were obviously higher than in RP (P0.05). Microbial richness and diversity in RP were obviously higher than in NP (P0.05), whereas no significant differences were observed between the RPCC and NP. The relative abundances of fungal genera Nectria, Myrothecium, Tomentella, and bacterial genus Skermanella were obviousl lower in RPCC and NP than in RP (P0.05). Correlation analysis that S-ACP activity was positively correlated with the content of rehmannioside D (P0.05). Fungal genera Engyodontium and Alternaria, and bacterial genera Pir4 lineage, Pirellula, Methyloversatilis, Brevundimonas, Ralstonia, and Acidibacter were obviously positively correlated with tuber dry weight (P0.05). Conversely, fungal genera Pseudaleuria, Nectria, Haematonectria, Ceratobasidium, and bacterial genera Streptomyces, Skermanella, RB41, Gemmatimonas, and Bacillus were obviously negatively correlated with dry weight (P0.05). The fungal genus Alternaria and bacterial genera Brevundimonas, Ralstonia, Acidibacter, and Dongia showed positive correlations with medicinal quality of R.glutinosa tuber, while fungal genera Pseudaleuria, Nectria, Stachybotrys, Fusarium, Gibberella, Ceratobasidium, and bacterial genera Sphingomonas, Skermanella, RB41, Gemmatimonas, and Bacillus were obviously negatively correlated (P0.05). ConclusionCaCN2 soil fumigation can significantly improve enzyme activities in replanted Rehmannia rhizosphere soil, enhance the utilization of available nutrients, reshape microbial community structure of replanted R.glutinosa at the family and genus level, and notably improve tuber agronomic traits and medicinal quality. This study provides a novel approach to alleviating replanting problems and offers insights for the integrated development of standardized cultivation techniques, including soil disinfection, nutrient-targeted regulation, and microbial inoculant application.

Given the increasing concern regarding antibacterial resistance, the antimicrobial properties of naphthoquinones have recently attracted significant attention. While 1,4-naphthoquinone and its derivatives have been extensively studied, the antibacterial properties of 5,8-dihydroxy-1,4-naphthoquinone derivatives remain relatively unexplored. This study presents a comprehensive in vitro and in vivo analysis of the antibacterial activity of 35 naturally sourced and chemically synthesized derivatives of 5,8-dihydroxy-1,4-naphthoquinone. Kirby-Bauer antibiotic testing identified three compounds with activity against methicillin-resistant Staphylococcus aureus (MRSA), with one compound (PNP-02) demonstrating activity comparable to vancomycin in minimum inhibitory concentration, minimum bactericidal concentration (MBC), and time-kill assays. Microscopic and biochemical analyses revealed that PNP-02 adversely affects the cell wall and cell membrane of MRSA. Mechanistic investigations, including proteomic sequencing analyses, Western blotting, and RT-qPCR assays, indicated that PNP-02 compromises cell membrane integrity by inhibiting arginine biosynthesis and pyrimidine metabolism pathways, thereby increasing membrane permeability and inducing bacterial death. In an in vivo mouse model of skin wound healing, PNP-02 exhibited antibacterial efficacy similar to vancomycin. The compound demonstrated low toxicity to cultured human cells and in hemolysis assays and remained stable during serum incubation. These findings suggest that PNP-02 possesses promising bioactivity against MRSA and represents a potential novel antibacterial agent.

Chinese Journal of School Health 2025;46(12):1760-1764
Objective:
To analyze the current status of clinical trial registration for childhood and adolescent obesity, so as to provide insights for the registration and implementation of related trials.
Methods:
ClinicalTrials.gov and the ChiCTR database were searched for obesity related clinical trial registrations up to 1 June 2025. Data included basic characteristics (registration region, date, funding source, status, sample size), trial design features, participant demographics, interventions, outcome measures, methodology, and reporting quality. Statistical and descriptive analyses were conducted.
Results:
A total of 1 450 registered studies were included, covering 59 regions globally. North America hosted the highest number of registrations (876, 60.41%), with the United States accounting for the largest share (771, 53.17%). The earliest registered study dated to 1985, while 2016 saw the highest annual registrations ( n =87). Funding sources predominantly originated from universities (834 studies, 57.52%). Currently, completed trials accounted for the majority (1 003 trials, 69.17%). Globally, the majority of studies employed sample sizes within the 11-50 range (331 studies, 22.83%). Interventional studies predominated in design type (1 186, 81.79%), predominantly employing randomized parallel group controlled trials. Main interventions included comprehensive lifestyle interventions, physical activity and exercise interventions, and diet and nutrition interventions. High frequency outcome indicators primarily involved body composition and anthropometric measurements, metabolic and biochemical indicators, etc. Methodology and reporting quality required improvement.
Conclusions
The registration of clinical trials related to childhood and adolescent obesity globally shows a positive development trend, but issues of regional imbalance and methodological limitations exist. It is necessary to strengthen clinical trial registration norms, optimize study designs, and focus on the innovation of interventions and the systematicity of outcome indicators.
