Huanglian Jiedutang (HLJDT), as a classical formula for clearing heat and removing toxins, has been widely applied in the treatment of various clinical diseases in recent years, particularly during the fire-heat stage of stroke, where it has attracted considerable attention. Based on previous studies, this paper systematically elaborates on the research progress on the active components of HLJDT, its clinical application in ischemic stroke, and advances in studies on its mechanisms of action. Modern pharmacological studies have demonstrated that HLJDT contains multiple active components, including baicalin, geniposide, and berberine. In the treatment of ischemic stroke, these components exert therapeutic effects through multi-target, multi-pathway, and multi-level mechanisms. Clinical studies have shown that HLJDT can increase cerebral blood flow, reduce cerebral infarct volume, and improve post-stroke physical dysfunction in patients with ischemic stroke. Experimental studies have indicated that HLJDT can improve neurological function scores and increase cerebral perfusion in experimental stroke models. In addition, the mechanisms underlying the anti-ischemic stroke effects of HLJDT may be related to anti-inflammatory and antioxidant activities, promotion of angiogenesis, and regulation of amino acid and energy metabolism. Although existing studies have confirmed that HLJDT exhibits multi-target and multi-pathway synergistic therapeutic characteristics, further large-sample randomized controlled trials are still needed to verify its long-term efficacy and to further elucidate the dynamic interaction network among components, targets, and pathways. Combined with network pharmacology and molecular docking analyses, this study further clarifies the synergistic targets of the core components (berberine, baicalin, and geniposide), providing a theoretical basis for in-depth research and clinical translation of HLJDT in the treatment of ischemic stroke.

As people’s attention to health continues to increase, the market demand for traditional Chinese medicine (TCM) is growing steadily. The quality and safety of Chinese medicinal materials have attracted unprecedented social attention. In particular, the issue of exogenous harmful residue pollution in TCM has become a hot topic of concern for both regulatory authorities and society. The Chinese Pharmacopoeia 2025 Edition further refines the detection methods and limit standards for exogenous harmful residues in TCM. This not only reflects China’s high-level emphasis on the quality and safety of TCM but also demonstrates the continuous progress made by China in the field of TCM safety supervision. Basis on this study, by systematically reviewing the development history of the detection standards for exogenous harmful residues in TCM and analyzing the revisions and updates of these detection standards in the Chinese Pharmacopoeia 2025 Edition, deeply explores the key points of the changes in the monitoring standards for exogenous harmful residues in TCM in the Chinese Pharmacopoeia 2025 Edition. Moreover, it interprets the future development directions of the detection of exogenous residues in TCM, aiming to provide a reference for the formulation of TCM safety supervision policies.

OBJECTIVE:
To compare the clinical efficacy of jingjin needling combined with rehabilitation training and conventional acupuncture combined with rehabilitation training for post-stroke spastic paralysis.
METHODS:
A total of 60 patients with post-stroke spastic paralysis were randomly divided into an observation group and a control group, 30 cases in each one. Both groups received conventional rehabilitation training. In the observation group, jingjin needling was applied at tendon blockage points of the shoulder, elbow, wrist, hip, knee, and ankle. In the control group, conventional acupuncture was applied at Jianyu (LI15), Quchi (LI11), Hegu (LI4), Biguan (ST31), Fengshi (GB31), Taichong (LR3), etc. on the affected side. Treatment was given once daily, 5 days a week for 4 weeks in both groups. The scores of clinical spasticity index (CSI), modified Ashworth scale, modified Barthel index (MBI), and Fugl-Meyer assessment scale (FMA) were evaluated before and after treatment, and the onset time was compared between the two groups.
RESULTS:
After treatment, the scores of CSI and modified Ashworth scale were decreased compared with those before treatment (P<0.001), while the scores of MBI and FMA were increased compared with those before treatment (P<0.001) in the two groups. After treatment, the scores of CSI and modified Ashworth scale in the observation group were lower than those in the control group (P<0.05), the MBI score in the observation group was higher than that in the control group (P<0.05). There was no statistically significant difference in FMA scores between the two groups (P>0.05). The onset time of the observation group was earlier than that in the control group (P<0.05).
CONCLUSION
Both jingjin needling combined with rehabilitation training and conventional acupuncture combined with rehabilitation training can effectively treat post-stroke spastic paralysis, jingjin needling combined with rehabilitation training exhibits better therapeutic effect and rapider onset.

ObjectiveTo investigate the mechanism by which Huanglian Jiedutang (HLJDT) inhibits pyroptosis and neuroinflammation in Alzheimer's disease (AD) mice via the NOD-like receptor protein 3 (NLRP3)/cysteinyl aspartate-specific protease-1 (Caspase)-1/gasdermin D (GSDMD) pathway. MethodsThirty APP/PS1 double transgenic mice were randomly and evenly divided into the model group (model group), the positive control group (Donepezil group, 0.65 mg·kg-1), and the HLJDT treatment group (HLJDT group, 5.2 g·kg-1). Ten C57BL/6 mice were assigned to the blank control group (control group). The Morris water maze and novel object recognition tests were used to evaluate learning and memory abilities. Nissl staining was employed to observe the morphology, quantity, and distribution of neurons in the hippocampal region. Golgi staining was used to examine the morphology and density of neuronal dendritic spines in the hippocampus. Real-time quantitative polymerase chain reaction (Real-time PCR) was performed to detect the mRNA expression of neuroinflammation-related factors and genes in the NLRP3/Caspase-1/GSDMD pyroptosis pathway in the hippocampus. Western blot was used to detect the expression of postsynaptic density protein 95 (PSD95), amyloid precursor protein (APP), inflammatory factors including nuclear factor-κB (NF-κB), phosphorylated NF-κB (p-NF-κB), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), as well as pyroptosis pathway-related proteins including NLRP3, Caspase-1, GSDMD, and GSDMD-N. ResultsCompared with the control group, the model group exhibited significantly decreased learning and memory abilities (P<0.01), reduced numbers of neurons in the hippocampal CA3 region and dendritic spines in the hippocampal CA1 region (P<0.01), and significantly increased hippocampal mRNA expression levels of NLRP3, Caspase-1, GSDMD, NF-κB, TNF-α, IL-1β, and IL-18 (P<0.01). Protein levels of PSD95 were markedly decreased, while the expression levels of NLRP3, Caspase-1, GSDMD, p-NF-κB/NF-κB, TNF-α, IL-1β, and APP were significantly elevated (P<0.01). Compared with the model group, both the Donepezil and HLJDT groups showed significantly improved learning and memory abilities (P<0.05, P<0.01), increased numbers of hippocampal neurons in the hippocampal CA3 region and dendritic spines in the hippocampal CA1 region (P<0.01), and significantly decreased hippocampal mRNA expression levels of NLRP3, Caspase-1, GSDMD, NF-κB, TNF-α, IL-1β, and IL-18 (P<0.05, P<0.01). Protein levels of NLRP3, Caspase-1, GSDMD, p-NF-κB/NF-κB, TNF-α, IL-1β, and APP were significantly downregulated, while PSD95 expression was significantly upregulated (P<0.05, P<0.01). There was no statistically significant difference in GSDMD-N levels in the Donepezil group, while GSDMD-N expression was significantly decreased in the HLJDT group (P<0.05). ConclusionThis study confirms that HLJDT can improve learning and memory abilities in APP/PS1 double transgenic mice, and attenuate neuronal loss and synaptic damage, possibly through inhibition of pyroptosis via the NLRP3/Caspase-1/GSDMD pathway.

Objective:To explore the independent association between handgrip strength and chronic kidney disease (CKD) in adult residents in Anhui Province using data from the China Adult Chronic Disease and Risk Factor Surveillance (2023).Methods:A multi-stage stratified cluster random sampling method was used to select residents aged ≥18 years for surveys, physical measurements, and laboratory tests. Relevant covariates were adjusted, and a multivariable logistic regression model was established to infer the association between handgrip strength and CKD, followed by subgroup analysis.Results:A total of 7 295 participants were included in the study, with age of (61.5±13.2) years, and 55.6% of the study participants were women. The results of the multivariate logistic regression analysis showed that with each 1.0 kg increase in handgrip strength, the risk for CKD decreased by 1.3% ( OR=0.987, 95% CI: 0.978-0.997). Compared with those with low handgrip strength, the people with moderate hasdgrip strength ( OR=0.818, 95% CI: 0.694-0.964) and high handgrip strength ( OR=0.729, 95% CI: 0.598-0.989) had lower risk for CKD. In the subgroup analysis, the association between handgrip strength and risk for CKD remained unchanged regardless age, sex, smoking status, and alcohol consumption statuys, and the prevalence of hypertension and hyperlipidemia (interaction P>0.05), except BMI and diabetes. Conclusion:The decline in handgrip strength is associated with an increased risk for CKD in adult residents in Anhui.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

The aim of this updated guideline is to provide comprehensive recommendations for the management of gout in patients with common comorbidities, such as chronic kidney disease(CKD), cardiovascular disease(CVD), diabetes, osteoarthritis(OA), and gastrointestinal disorders. This guideline was developed by a multidisciplinary expert panel consisting of specialists in endocrinology, rheumatology, nephrology, cardiology, gastroenterology, and methodology. The development process adhered to standard methodologies, including PICO(population, intervention, comparator, and outcomes) question deconstruction, systematic literature review, the Grading of Recommendations Assessment, Development and Evaluation(GRADE) for evidence and recommendation evaluation, Delphi voting, and expert consensus. The guideline presents 26 evidence-based recommendations addressing 7 clinical questions for patients with hyperuricemia and gout in the context of comorbidities. Key recommendations include the maintenance of strict serum urate targets, particularly for patients with CKD stage≥3, chronic gouty arthritis, and OA, in order to prevent disease progression. In patients with CVD or diabetes, intra-articular triamcinolone is preferred over systemic glucocorticoids. Prioritized anti-inflammatory treatments for patients with CKD, gastrointestinal diseases and OA are recommended. The guideline also introduces emerging therapies, such as interleukin-1 inhibitors and selective urate transport inhibitors, as potential treatment options for refractory cases. The update offers a comprehensive, patient-centered approach to managing gout, particularly in individuals with associated comorbidities. Multidisciplinary collaboration and emerging new treatments and evidence ensure the optimization of the recommendations.

Objective:To explore the application value of the double-low technique of auto-prescription technique combined with iterative reconstruction algorithm in CT pulmonary angiography (CTPA).Methods:A total of 86 patients who were clinically suspected of having pulmonary embolism and underwent CTPA examination in the First Affiliated Hospital of Dalian Medical University were prospectively collected and randomly assigned to a control group ( n = 45) and an observation group ( n = 41) according to the random number table method. In the control group, a tube voltage of 120 kVp was used with a standard iodine contrast agent dose of 60 ml, and images were reconstructed using the 40% adaptive statistical iterative reconstruction algorithm (ASIR-V). In the observation group, the tube voltage was set by auto-prescription technique, and 0.4 ml/kg of personalized low iodine contrast agent was used. Images were reconstructed with 40%, 60%, and 80% ASIR-V, respectively, and designated as observation 1, observation 2, and observation 3 respectively. The volume CT dose index (CTDI vol), dose-length product (DLP), and effective dose ( E) were recorded and compared among the four groups. The CT values and standard deviation (SD) of the main pulmonary artery, left and right pulmonary arteries, as well as the left and right pulmonary lobe arteries were measured, and the signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of these arteries were calculated. Additionally, the SD value at the contrast medium concentration in the superior vena cava was measured, and the artifact index (AI) was subsequently calculated. Two observers independently assessed the visibility of the pulmonary arteries, image noise, and sclerosis artifacts in the superior vena cava using a blinded method. Results:The E in the observation group was 3.28 (2.08, 3.93) mSv, which was significantly lower than that in the control group [5.03 (4.86, 5.20)] mSv, and the difference was statistically significant ( Z = 174.00, P < 0.05). The contrast agent dosage in the observation group was 28 (25, 30) ml, which was lower than that in the control group (60 ml), and the difference was statistically significant ( Z = 0, P < 0.05). The CT values for the main pulmonary artery and the left and right pulmonary lobe arteries in the observation group were higher than those in the control group, and the differences were all statistically significant ( t = -3.65 to -3.89, P < 0.05). The SNR and CNR of the observation groups 2 and 3 were greater than those of the control group ( t = -9.20 to -2.98, P < 0.05). The consistency of subjective evaluations between the two observers was good ( Kappa = 0.729 - 0.879, P < 0.05). There was no statistically significant difference in the subjective score of pulmonary artery visibility between the control and observation group ( P > 0.05). The subjective scores for image noise in observation group 2 and group 3 were higher than those in the control group ( U =598.50, 654.00, P < 0.05). The presence of artifacts due to sclerosis in the superior vena cava was significantly lower in the observation group compared to the control group ( χ2 = 46.09, P < 0.001). Conclusions:The combination of auto-prescription technique with ASIR-V reconstruction algorithm and low contrast agent imaging protocol can reduce the radiation dose and contrast agent dose without compromising image quality, and enable personalized double low CTPA imaging.
