ObjectiveThe development trend and knowledge structure of the research on human use experience (HUE) of traditional Chinese medicine (TCM) were systematically reviewed, and the core challenges and future directions were identified. This study aims to provide reference for the construction of a scientific and feasible research and development framework and evidence transformation system. MethodsLiterature related to "human use experience" published from January 1, 2019 to July 31, 2025 was retrieved from the China National Knowledge Infrastructure (CNKI), Wanfang, China Science and Technology Journal Database (VIP), and PubMed databases. Bibliometric visualization was conducted using Excel, VOSviewer, and CiteSpace, followed by in-depth reading and thematic summarization of core literature. ResultsA total of 181 papers were included for bibliometric analysis, with 45 articles used for in-depth thematic mining. The analysis showed that the number of publications on HUE research has increased in a stepwise manner over the past five years. Yang Zhongqi (24 times) was the core of the author network, the journal with the highest number of publications was China Journal of Chinese Materia Medica, the institutions publishing the most articles were mainly research institutions, regulatory agencies, hospitals, and universities, high-frequency keywords included "new TCM drugs", "real-world studies", and "clinical comprehensive evaluation", keyword clustering analysis formed three major clusters: Policy orientation, application fields, and methodological approaches. Thematic analysis reveals that HUE-based evaluation should be integrated throughout the research and development process, encompassing three dimensions: TCM theory, clinical value, and pharmaceutical fundamentals, with toxic herbs and compatibility contraindications being key foci. Data collection primarily relies on empirical data, while real-world data constitute the primary source for clinical research, with efficacy and safety as the shared core. Data management emphasizes quality control and statistical analysis; however, the management of bias and confounding remains a critical bottleneck in evidence transformation. In practice, HUE-based approaches have successfully supported the registration and evaluation of multiple categories of new TCM drugs. ConclusionThe research on HUE of TCM has formed a policy-driven pattern characterized by, rapid development and close link with regulatory practice. A technical framework covering the whole chain of research and development has been constructed with clinical value as the core, which provides methodological basis and strategy reference for the scientific transformation of HUE of TCM from "experience" to "evidence".

Objective:
To analyze the trends in incidence and mortality of prostate cancer in Ningbo City, Zhejiang Province, so as to provide insights into the prevention and control of prostate cancer.
Methods:
Data of the incidence and mortality of prostate cancer in Ningbo City from 2011 to 2023 were collected through Ningbo Chronic Disease Collaborative Management System. The incidence and mortality of prostate cancer were calculated and standardized by the data from the sixth national population census in 2010 and the Segi's world standard population in 1960. The trends in incidence and mortality of prostate cancer were evaluated using average annual percent change (AAPC).
Results:
A total of 15 411 cases of prostate cancer were reported in Ningbo City from 2011 to 2023, and the crude incidence, Chinese-standardized incidence and world-standardized incidence were 39.62/105, 22.18/105 and 16.49/105, respectively, showing upward trends (AAPC=14.782%, 10.390% and 10.608%, all P<0.05). The Chinese-standardized incidence of prostate cancer was higher in urban areas than in rural areas, and both showed upward trends (25.14/105 vs. 19.44/105; AAPC=9.057% and 14.272%, both P<0.05). The crude incidence of prostate cancer in the groups aged 50-<60 years, 60-<70 years, 70-<80 years and ≥80 years showed upward trends (AAPC=11.657%, 14.031%, 10.734% and 5.300%, all P<0.05). A total of 3 739 deaths were reported, and the crude mortality, Chinese-standardized mortality and world-standardized mortality were 9.66/105, 5.23/105 and 3.71/105, respectively, showing upward trends (AAPC=8.458%, 3.620% and 3.602%, all P<0.05). The Chinese-standardized mortality of prostate cancer was higher in urban areas than in rural areas, and both showed upward trends (5.35/105 vs. 5.13/105; AAPC=3.183% and 3.962%, both P<0.05). The crude mortality of prostate cancer the groups ageds ≥80 years showed an upward trend (AAPC=7.482%, P<0.05).
Conclusions
From 2011 to 2023, the incidence and mortality of prostate cancer in Ningbo City showed upward trends. Special attention should be paid to urban residents, and prostate cancer screening should be strengthened among males aged 50 years and older.

ObjectiveTo unveil the mechanism of Jianpi Huogu prescription (JPHGP) in ameliorating the dyslipidemia of steroid-induced osteonecrosis of the femur head (SONFH) by oxylipidomics combined with transcriptomics. MethodsSixty SD rats were assigned into normal, model, low-, medium-, and high-dose (2.5, 5, 10 g·kg-1, respectively) JPHGP, and Jiangushengwan (1.53 g·kg-1) groups. Lipopolysaccharide was injected into the tail vein at a dose of 20 μg·kg-1 on days 1 and 2, and methylprednisolone sodium succinate was injected at a dose of 40 mg·kg-1 into the buttock muscle on days 3 to 5. The normal group received an equal volume of normal saline. Drug administration by gavage began 4 weeks after the last injection, and samples were taken after administration for 8 weeks. Hematoxylin-eosin staining was conducted to reveal the histopathological changes of the femoral head, and the number of adipocytes, the rate of empty bone lacunae, and the trabecular area were calculated. Micro-computed tomography was used for revealing the histological and histomorphometrical changes of the femoral head. Enzyme-linked immunosorbent assay was employed to measure the serum levels of triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), apolipoprotein A1 (ApoA1), and apolipoprotein B (ApoB). At the same time, the femoral head was collected for oxylipidomic and transcriptomic detection. The differential metabolites and differential genes were enriched and analyzed, and the target genes regulating lipid metabolism were predicted. The predicted target proteins were further verified by molecular docking, immunohistochemistry, and Western blot. ResultsCompared with the normal group, the model group showcased thinning of the femoral head, trabecular fracture, karyopyknosis, subchondral cystic degeneration, increases in the number of adipocytes and the rate of empty bone lacunae (P<0.01), a reduction in the trabecular area (P<0.01), decreases in BMD, Tb.Th, Tb.N, and BV/TV, and increases in Tb.Sp and BS/BV (P<0.01). Compared with the model group, the JPHGP groups showed no obvious thinning of the femoral head or subchondroidal cystic degeneration. The high- and medium-dose JPHGP groups presented declines in the number of adipocytes and the rate of empty bone lacunae, an increase in the trabecular area (P<0.05, P<0.01), rises in BMD, Tb.Th, Tb.N, and BV/TV, and decreases in Tb.Sp and BS/BV (P<0.05, P<0.01). Compared with the normal group, the model group showcased raised serum levels of TG, TC, LDL, and ApoB and lowered serum levels of HDL and ApoA1 (P<0.01). Compared with the model group, the JPHGP groups had lowered serum levels of TG, TC, LDL, and ApoB (P<0.05, P<0.01) and a risen serum level of ApoA1 (P<0.05, P<0.01). Moreover, the serum level of HDL in the high-dose JPHGP group increased (P<0.01). A total of 19 different metabolites of disease set and drug set were screened out by oxylipidomics of the femoral head, and 119 core genes with restored expression were detected by transcriptomics. The enriched pathways were mainly concentrated in inflammation, lipids, apoptosis, and osteoclast differentiation. Molecular docking, immunohistochemistry, and Western blot results showed that compared with the normal group, the model group displayed increased content of 5-lipoxygenase (5-LO) and peroxisome proliferator-activated receptor γ (PPARγ) in the femoral head (P<0.01). Compared with the model group, medium- and high-dose JPHGP reduced the content of 5-LO and PPARγ (P<0.05, P<0.01). ConclusionJPHGP can restore the levels of oxidized lipid metabolites by regulating the 5-LO-PPARγ axis to treat SONFH in rats. Relevant studies provide experimental evidence for the efficacy mechanism of JPHGP in the treatment of SONFH.

OBJECTIVE:
To explore the effect and mechanism of acupuncture at "Weizhong" (BL40) on microcirculation of paravertebral skeletal muscle in rats with chronic blunt injury of lumbar muscle based on the insulin-like growth factor-1 (IGF-1)/phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) pathway.
METHODS:
Forty-eight SPF-grade SD rats were randomized into a blank group (8 rats) and a modeling group (40 rats). Chronic blunt injury model was established by weight impact method in the modeling group. Forty rats were successfully modeled, and were randomly divided into a model group, an acupuncture at Weizhong group (Weizhong group), an acupuncture at non-acupoint group (non-acupoint group), an inhibitor group, and an inhibitor+acupuncture at Weizhong group (inhibitor+Weizhong group), 8 rats in each group. In the Weizhong group and the inhibitor+Weizhong group, acupuncture was applied at bilateral "Weizhong" (BL40). In the non-acupoint group, acupuncture was applied at non-acupoints, i.e. points 0.5 cm inward from bilateral "Weizhong" (BL40). The acupuncture intervention was delivered 20 min each time, once a day for continuous 2 weeks. In the inhibitor group and the inhibitor+Weizhong group, intraperitoneal injection of IGF-1 receptor (IGF-1R) inhibitor was given once a day, at a dosage of 2 mg/100 g, for continuous 2 weeks. Before modeling and on the 1st, 7th and 14th days of intervention, the body mass was measured. Before and after modeling, and after intervention, the limb grip strength and paw withdrawal threshold (PWT) were measured. After intervention, the morphology of psoas muscle was observed by HE staining; the ultrastructure of psoas muscle capillaries was observed by electron microscopy; the levels of serum vascular endothelial growth factor (VEGF) and endothelial nitric oxide synthase (eNOS) were detected by ELISA; and the protein and mRNA expression of IGF-1, IGF-1R, PI3K, AKT of psoas muscle was detected by Western blot and real-time PCR.
RESULTS:
Compared with the blank group, in the model group, the body mass on the 7th and 14th days of intervention, the limb grip strength, and the PWT of left and right hind feet were decreased (P<0.001, P<0.01); the skeletal muscle cells showed enlarged intercellular space, loosely arranged and irregularly shaped, the capillaries in the psoas muscle tissues were edematous, and the lumen of the blood vessels was obviously atrophied; the levels of serum VEGF and eNOS were decreased (P<0.001); in psoas muscle, the protein expression of IGF-1 and IGF-1R, as well as the p-PI3K/PI3K, p-AKT/AKT values were decreased (P<0.001), the mRNA expression of IGF-1, IGF-1R, PI3K and AKT was decreased (P<0.001, P<0.05). Compared with the model group, in the Weizhong group, the body weight was increased on the 7th and 14th days of intervention (P<0.001), the limb grip strength and the PWT of the left and right hind feet were increased (P<0.001, P<0.01); the arrangement of the skeletal muscle cells was relatively tight and the intercellular space was reduced, the blood vessels tended to be regular and the structure of the basement membrane was continuous, while the lumens of blood vessels were collapsed locally; the levels of serum VEGF and eNOS were increased (P<0.001); in psoas muscle, the protein expression of IGF-1 and IGF-1R, as well as the p-PI3K/PI3K, p-AKT/AKT values were increased (P<0.001), the mRNA expression of IGF-1, IGF-1R, PI3K and AKT was increased (P<0.001, P<0.01). Compared with the model group, in the inhibitor group, the body mass was decreased on the 7th and 14th days of intervention (P<0.05, P<0.01); the limb grip strength and the PWT of the left hind foot were decreased (P<0.01, P<0.001); the intercellular space of skeletal muscle cells was larger, the nuclei of the cells and erythrocytes were scattered in the intercellular space, the damage of the capillaries in the muscular tissues was serious, the collagen fibers were sparsely distributed and disorganized; the levels of serum VEGF and eNOS were decreased (P<0.001, P<0.01); in psoas muscle, the protein expression of IGF-1 and IGF-1R, as well as the p-PI3K/PI3K and p-AKT/AKT values were decreased (P<0.01, P<0.05, P<0.001), the mRNA expression of IGF-1, IGF-1R, PI3K, and AKT was decreased (P<0.01, P<0.001, P<0.05).

BACKGROUND:
Disease-modifying therapies have been approved for the treatment of relapsing multiple sclerosis (RMS). The present study aims to examine the safety of teriflunomide in Chinese patients with RMS.
METHODS:
This non-randomized, multi-center, 24-week, prospective study enrolled RMS patients with variant (c.421C>A) or wild type ABCG2 who received once-daily oral teriflunomide 14 mg. The primary endpoint was the relationship between ABCG2 polymorphisms and teriflunomide exposure over 24 weeks. Safety was assessed over the 24-week treatment with teriflunomide.
RESULTS:
Eighty-two patients were assigned to variant ( n = 42) and wild type groups ( n = 40), respectively. Geometric mean and geometric standard deviation (SD) of pre-dose concentration (variant, 54.9 [38.0] μg/mL; wild type, 49.1 [32.0] μg/mL) and area under plasma concentration-time curve over a dosing interval (AUC tau ) (variant, 1731.3 [769.0] μg∙h/mL; wild type, 1564.5 [1053.0] μg∙h/mL) values at steady state were approximately similar between the two groups. Safety profile was similar and well tolerated across variant and wild type groups in terms of rates of treatment emergent adverse events (TEAE), treatment-related TEAE, grade ≥3 TEAE, and serious adverse events (AEs). No new specific safety concerns or deaths were reported in the study.
CONCLUSION:
ABCG2 polymorphisms did not affect the steady-state exposure of teriflunomide, suggesting a similar efficacy and safety profile between variant and wild type RMS patients.

In 2040, neurodegenerative diseases (NDD) will overtake cancer as the second leading cause of death after cardiovascular and cerebrovascular diseases. Therefore, the search for effective intervention measures has become the top priority to deal with this difficult burden. Hyperbaric oxygen therapy (HBOT) has been used for the past 50 years to treat conditions such as decompression sickness, carbon monoxide poisoning and radiation damage. In recent years, studies have confirmed that HBOT has good effects in improving cognitive impairment after brain injury and stroke, and alleviating neurodegeneration and dysfunction related to NDD. Here we reviewed the pathogenesis and treatment state of NDD, introduced the application of HBOT in animal models and clinical studies of NDD, and expounded the application potential of HBOT in the treatment of NDD from the perspective of mitochondrial function, neuroinflammation, neurogenesis and angiogenesis, oxidative stress, apoptosis, microcirculation and epigenetics.

Polygonati Rhizoma demonstrates significant potential for addressing both chronic and hidden hunger. The supply of high-quality seedlings is a primary factor influencing the development of the Polygonati Rhizoma industry. Warm water soaking is often used in agriculture to promote the rapid germination of seeds, while its application and molecular mechanism in Polygonati Rhizoma have not been reported. To rapidly obtain high-quality seedlings, this study treated Polygonatum kingianum var. grandifolium seeds with sand storage at low temperatures, warm water soaking, and cultivation temperature gradients. The results showed that the culture at 25 ℃ or sand storage at 4 ℃ for 2 months rapidly broke the seed dormancy of P. kingianum var. grandifolium, while the culture at 20 ℃ or sand storage at 4 ℃ for 1 month failed to break the seed dormancy. Soaking seeds in 60 ℃ warm water further increased the germination rate, germination potential, and germination index. Specifically, the seeds soaked at 60 ℃ and cultured at 25 ℃ without sand storage treatment(Aa25) achieved a germination rate of 78. 67%±1. 53% on day 42 and 83. 40%±4. 63% on day 77. The seeds pretreated with sand storage at 4 ℃ for 2 months, soaked in 60 ℃ water, and then cultured at 25 ℃ achieved a germination rate comparable to that of Aa25 on day 77. Transcriptomic analysis indicated that warm water soaking might promote germination by triggering reactive oxygen species( ROS), inducing the expression of heat shock factors( HSFs) and heat shock proteins( HSPs), which accelerated DNA replication, transcript maturation, translation, and processing, thereby facilitating the accumulation and turnover of genetic materials. According to the results of indoor controlled experiments and field practices, maintaining a germination and seedling cultivation environment at approximately 25 ℃ was crucial for the one-year seedling cultivation of P. kingianum var. grandifolium.

A combination of the "disease-syndrome-symptom" approach was used to study the syndrome characterization and features of dampness-heat obstruction syndrome in papain-induced knee osteoarthritis(KOA) model rats during the disease process. Forty-eight male SD rats were randomly divided into sham and model groups. The KOA model was established by injecting a mixture of papain and L-cysteine into the joint cavity on days 1, 3, and 5. During the 8 weeks following model establishment, the rats were assessed weekly for the plantar mechanical pain threshold, knee joint diameter, local skin temperature of the knee joint, weight-bearing difference between the two hind feet, and the modified Lequesne MG score of the knee joint. Samples were collected at 1, 2, 4, 6, and 8 weeks after model establishment to observe the gross lesions in cartilage and synovium. Histopathological changes in joint tissues were examined using hematoxylin-eosin, Masson's trichrome, and Senna red O-solid green staining. ELISA and immunohistochemical analysis were performed to detect the levels of interleukin(IL)-1β, IL-6, tumor necrosis factor(TNF)-α, prostaglandin E2(PGE2), and the expression of aquaporins(AQP) 1 and 3 in serum and synovium. The results showed that the ink score of articular cartilage in the model group significantly increased from 4 to 8 weeks, the cartilage Mankin's score and the percentage of Masson-positive area in cartilage increased significantly from 1 to 8 weeks. The percentage of red-stained area for cartilage proteoglycans decreased significantly from 1 to 8 weeks. The synovitis score from 1 to 6 weeks and the percentage of blue-stained collagen fibers in the synovium from 1 to 8 weeks increased significantly, with statistically significant differences compared to the sham group. The mechanical pain threshold in the model group significantly decreased from 1 to 8 weeks, the knee joint diameter significantly increased from 1 to 6 weeks, and the local skin temperature of the knee joint, the weight-bearing difference between the two hind feet, and the modified Lequesne MG score from 1 to 5 weeks significantly increased, all with statistically significant differences compared to the sham group. The levels of IL-1β, IL-6, TNF-α, and PGE2 in serum and synovium of the model group significantly increased from 1 to 6 weeks. Serum TNF-α and PGE2, and synovial IL-1β, also significantly increased at 8 weeks. The levels of cartilage AQP1 and AQP3 significantly increased from 1 to 4 weeks, while synovial AQP1 and AQP3 increased significantly from 1 to 6 weeks, with all differences statistically significant compared to the sham group. In conclusion, papain-induced KOA rats exhibited pathological changes, including articular cartilage degeneration and synovial inflammation, within 1 week of induction. The KOA rats showed characteristics of dampness-heat obstruction syndrome, such as joint pain, swelling, elevated skin temperature, and decreased function, as well as increased inflammatory factors and AQP1、AQP3 in serum and joint tissues within 5 to 6 weeks of disease onset. These results provide an experimental model for studying the syndromes of KOA with dampness-heat obstruction syndrome.

Jiuwei Xifeng Granules have become a Chinese patent medicine in the market. Because the formula contains Os Draconis, a top-level protected fossil of ancient organisms, the formula was to be improved by replacing Os Draconis with Ostreae Concha. To evaluate whether the improved formula has the same effectiveness and safety as the original formula, a randomized, double-blind, parallel-controlled, equivalence clinical trial was conducted. This study enrolled 288 tic disorder(TD) of children and assigned them into two groups in 1∶1. The treatment group and control group took the modified formula and original formula, respectively. The treatment lasted for 6 weeks, and follow-up visits were conducted at weeks 2, 4, and 6. The primary efficacy endpoint was the difference in Yale global tic severity scale(YGTSS)-total tic severity(TTS) score from baseline after 6 weeks of treatment. The results showed that after 6 weeks of treatment, the declines in YGTSS-TSS score showed no statistically significant difference between the two groups. The difference in YGTSS-TSS score(treatment group-control group) and the 95%CI of the full analysis set(FAS) were-0.17[-1.42, 1.08] and those of per-protocol set(PPS) were 0.29[-0.97, 1.56], which were within the equivalence boundary [-3, 3]. The equivalence test was therefore concluded. The two groups showed no significant differences in the secondary efficacy endpoints of effective rate for TD, total score and factor scores of YGTSS, clinical global impressions-severity(CGI-S) score, traditional Chinese medicine(TCM) response rate, or symptom disappearance rate, and thus a complete evidence chain with the primary outcome was formed. A total of 6 adverse reactions were reported, including 4(2.82%) cases in the treatment group and 2(1.41%) cases in the control group, which showed no statistically significant difference between the two groups. No serious suspected unexpected adverse reactions were reported, and no laboratory test results indicated serious clinically significant abnormalities. The results support the replacement of Os Draconis by Ostreae Concha in the original formula, and the efficacy and safety of the modified formula are consistent with those of the original formula.
