Objective:To analyze the registration status of clinical trials of TCM treatment for functional dyspepsia (FD); To provide references for relevant clinical trial registration and implementation.Methods:The clinical registration trials of TCM for the treatment of FD were retrieved from ChiCTR and clinicaltrials.gov until January 1st, 2025. Excel 2019 was used to extract and analyze study characteristics, including basic information (registration time, country/region, institution, funding source), study features and quality (study type, trial design, phase, number of centers, sample size, interventions, outcome measures, methodological quality, reporting quality), as well as recruitment status and ethical review.Results:A total of 89 registered studies were included. Registration began in 2008 with 3 studies, peaking in 2021 with 14 studies. The studies involved 6 countries, with domestic trials covering 18 provincial-level regions in China and 52 clinical trial institutions. Primary funding sources were national funding and pharmaceutical company support. Most studies were interventional with randomized parallel-controlled designs, commonly using simple randomization. Post-marketing drug trials were the most frequent phase, and single-center trials predominated, involving a total sample size of 19 776 cases. Common interventions included acupuncture/massage and Chinese patent medicines. Frequently used outcome measures were effectiveness rate, symptom evaluation, and quality of life assessment, though issues existed with non-standardized reporting and lack of TCM-specific indicators. Methodological quality needed further improvement.Conclusions:Although the number of registered clinical trials of TCM treatment for FD has increased, the overall quantity remains insufficient. Researchers should emphasize optimization of registration details and study protocols to further enhance registration quality.

With the widespread adoption of low-dose CT screening and the extensive application of high-resolution CT, the detection rate of sub-centimeter lung nodules has significantly increased. How to scientifically manage these nodules while avoiding overtreatment and diagnostic delays has become an important clinical issue. Among them, lung nodules with a consolidation tumor ratio less than 0.25, dominated by ground-glass shadows, are particularly worthy of attention. The therapeutic challenge for this group is how to achieve precise and complete resection of nodules during surgery while maximizing the preservation of the patient's lung function. The "watershed topography map" is a new technology based on big data and artificial intelligence algorithms. This method uses Dicom data from conventional dose CT scans, combined with microscopic (22-24 levels) capillary network anatomical watershed features, to generate high-precision simulated natural segmentation planes of lung sub-segments through specific textures and forms. This technology forms fluorescent watershed boundaries on the lung surface, which highly fit the actual lung anatomical structure. By analyzing the adjacent relationship between the nodule and the watershed boundary, real-time, visually accurate positioning of the nodule can be achieved. This innovative technology provides a new solution for the intraoperative positioning and resection of lung nodules. This consensus was led by four major domestic societies, jointly with expert teams in related fields, oriented to clinical practical needs, referring to domestic and foreign guidelines and consensus, and finally formed after multiple rounds of consultation, discussion, and voting. The main content covers the theoretical basis of the "watershed topography map" technology, indications, operation procedures, surgical planning details, and postoperative evaluation standards, aiming to provide scientific guidance and exploration directions for clinical peers who are currently or plan to carry out lung nodule resection using the fluorescent microscope watershed analysis method.

This study aims to investigate the potential effect of the water extract of fresh Rehmanniae Radix on hypercholesterolemia in mice that was induced by a high-fat and high-cholesterol diet and explore its possible mechanism from bile acid reabsorption. Male C57BL/6 mice were randomly assigned into the following groups: control, model, low-and high-dose(4 and 8 g·kg~(-1), respectively) fresh Rehmanniae Radix, and positive drug(simvastatin, 0.05 g·kg~(-1)). Other groups except the control group were fed with a high-fat and high-cholesterol diet for 6 consecutive weeks to induce hypercholesterolemia. From the 6th week, mice were administrated with corresponding drugs daily via gavage for additional 6 weeks, while continuing to be fed with a high-fat and high-cholesterol diet. Serum levels of total cholesterol(TC), triglycerides(TG), low density lipoprotein-cholesterol(LDL-c), high density lipoprotein-cholesterol(HDL-c), and total bile acid(TBA), as well as liver TC and TG levels and fecal TBA level, were determined by commercial assay kits. Hematoxylin-eosin(HE) staining, oil red O staining, and transmission electron microscopy were performed to observe the pathological changes in the liver. Three livers samples were randomly selected from each of the control, model, and high-dose fresh Rehmanniae Radix groups for high-throughput transcriptome sequencing. Differentially expressed genes were mined and KEGG pathway enrichment analysis was performed to predict the key pathways and target genes of the water extract of fresh Rehmanniae Radix in the treatment of hypercholesterolemia. RT-qPCR was employed to measure the mRNA levels of cholesterol 7α-hydroxylase(CYP7A1) and cholesterol 27α-hydroxylase(CYP27A1) in the liver. Western blot was employed to determine the protein levels of CYP7A1 and CYP27A1 in the liver as well as farnesoid X receptor(FXR), apical sodium-dependent bile acid transporter(ASBT), and ileum bile acid-binding protein(I-BABP) in the ileum. The results showed that the water extract of fresh Rehmanniae Radix significantly lowered the levels of TC and TG in the serum and liver, as well as the level of LDL-c in the serum. Conversely, it elevated the level of HDL-c in the serum and TBA in feces. No significant difference was observed in the level of TBA in the serum among groups. HE staining, oil red O staining, and transmission electron microscopy showed that the water extract reduced the accumulation of lipid droplets in the liver. Further mechanism studies revealed that the water extract of fresh Rehmanniae Radix significantly down-regulated the protein levels of FXR and bile acid reabsorption-related proteins ASBT and I-BABP. Additionally, it enhanced CYP7A1 and CYP27A1, the key enzymes involved in bile acid synthesis. Therefore, it is hypothesized that the water extract of fresh Rehmanniae Radix may exert an anti-hypercholesterolemic effect by regulating FXR/ASBT/I-BABP signaling, inhibiting bile acid reabsorption, and increasing bile acid excretion, thus facilitating the conversion of cholesterol to bile acids.

ObjectiveTo investigate the ameliorative effect of paeonol on acute alcohol-induced hepatic inflammation in mice via the regulation of the short-chain fatty acids (SCFAs)-specific receptor GPR43/mitogen-activated protein kinase (MAPK) signaling pathway. MethodsC57BL/6 mice were randomly divided into five groups: blank control group, model group, low-dose paeonol group (120 mg·kg-1), high-dose paeonol group (480 mg·kg-1), and silybin group (36.8 mg·kg-1). A mouse model of alcohol-induced liver disease (ALD) was established by ad libitum administration of a Lieber-DeCarli alcohol liquid diet. Serum lipid levels, liver function, inflammatory cytokines, and oxidative stress markers were measured. Liver hematoxylin-eosin (HE) staining and Oil Red O staining were performed to validate successful modeling. Western blot analysis was used to assess the expression levels of zonula occludens-1 (ZO-1), Claudin-1, and proteins related to the GPR43/MAPK signaling pathway in the colonic tissue. Immunohistochemistry was employed to detect the protein expression of GPR43, ZO-1, and Claudin-1 in the colon. Then 16S rDNA sequencing was performed to analyze differences in intestinal flora between the model group and the high-dose paeonol group. Additionally, fecal microbiota transplantation (FMT) experiments were conducted to validate the regulatory effect of paeonol on ALD via modulation of intestinal flora. ResultsCompared with the blank control group, the model group showed significantly elevated serum lipid levels, oxidative stress, and inflammatory cytokine expression (P<0.01). Liver histology revealed increased inflammatory infiltration and lipid droplet accumulation. Colonic mucosal injury and impaired intestinal barrier function were observed. Levels of MAPK pathway-related proteins in the colonic tissue were upregulated (P<0.01), while GPR43, ZO-1, and Claudin-1 protein expression levels were significantly decreased (P<0.01). The composition and abundance of the intestinal flora were markedly altered, with a reduced Bacteroidetes-to-Firmicutes ratio and decreased relative abundances of Eubacterium, Parabacteroides, Erysipelothrix, and Adlercreutzia, alongside increased abundances of Clostridium butyricum, Enterococcus, and Helicobacter pylori in the model group. Compared with the model group, paeonol significantly reduced serum lipid levels, oxidative stress responses, and the expression of inflammatory cytokines in ALD mice (P<0.05, P<0.01). It also attenuated hepatic lipid accumulation, restored intestinal barrier function, and repaired the structural integrity of liver and colonic tissues. The protein expression levels of ZO-1, Claudin-1, and GPR43 in the colonic tissue were significantly increased (P<0.05, P<0.01), while those of MAPK pathway-related proteins were significantly decreased (P<0.05, P<0.01). The intestinal flora dysbiosis was effectively alleviated, rendering its composition closer to that of normal mice. The efficacy of paeonol in modulating ALD was further confirmed by FMT experiments, supporting its mechanistic involvement in the SCFAs-GPR43/MAPK signaling pathway. ConclusionPaeonol exerts a protective effect against ALD in mice, which may be mediated through regulation of the SCFAs-GPR43/MAPK signaling pathway, thereby achieving anti-inflammatory effects and improving intestinal barrier function.

OBJECTIVE:
To evaluate the clinical efficacy and safety of Yangxue Qingnao Pills (YXQNP) combined with amlodipine in treating patients with grade 1 hypertension.
METHODS:
This is a multicenter, randomized, double-blind, and placebo-controlled study. Adult patients with grade 1 hypertension of blood deficiency and Gan (Liver)-yang hyperactivity syndrome were randomly divided into the treatment or the control groups at a 1:1 ratio. The treatment group received YXQNP and amlodipine besylate, while the control group received YXQNP's placebo and amlodipine besylate. The treatment duration lasted for 180 days. Outcomes assessed included changes in blood pressure, Chinese medicine (CM) syndrome scores, symptoms and target organ functions before and after treatment in both groups. Additionally, adverse events, such as nausea, vomiting, rash, itching, and diarrhea, were recorded in both groups.
RESULTS:
A total of 662 subjects were enrolled, of whom 608 (91.8%) completed the trial (306 in the treatment and 302 in the control groups). After 180 days of treatment, the standard deviations and coefficients of variation of systolic and diastolic blood pressure levels were lower in the treatment group compared with the control group. The improvement rates of dizziness, headache, insomnia, and waist soreness were significantly higher in the treatment group compared with the control group (P<0.05). After 30 days of treatment, the overall therapeutic effects on CM clinical syndromes were significantly increased in the treatment group as compared with the control group (P<0.05). After 180 days of treatment, brachial-ankle pulse wave velocity, ankle brachial index and albumin-to-creatinine ratio were improved in both groups, with no statistically significant differences (P>0.05). No serious treatment-related adverse events occurred during the study period.
CONCLUSIONS
Combination therapy of YXQNP with amlodipine significantly improved symptoms such as dizziness and headache, reduced blood pressure variability, and showed a trend toward lowering urinary microalbumin in hypertensive patients. These findings suggest that this regimen has good clinical efficacy and safety. (Registration No. ChiCTR1900022470).

OBJECTIVE:
To explore the therapeutic effects and underlying mechanisms of Dendrobium officinale (Tiepi Shihu) extract (DOE) on insomnia.
METHODS:
Forty-two male Sprague-Dawley rats were randomly divided into 6 groups (n=7 per group): normal control, model control, melatonin (MT, 40 mg/kg), and 3-dose DOE (0.25, 0.50, and 1.00 g/kg) groups. Rats were raised in a strong-light (10,000 LUX) and -noise (>80 db) environment (12 h/d) for 16 weeks to induce insomnia, and from week 10 to week 16, MT and DOE were correspondingly administered to rats. The behavior tests including sodium pentobarbital-induced sleep experiment, sucrose preference test, and autonomous activity test were used to evaluate changes in sleep and emotions of rats. The metabolic-related indicators such as blood pressure, blood viscosity, blood glucose, and uric acid in rats were measured. The pathological changes in the cornu ammonis 1 (CA1) region of rat brain were evaluated using hematoxylin and eosin staining and Nissl staining. Additionally, the sleep-related factors gamma-aminobutyric acid (GABA), glutamate (GA), 5-hydroxytryptamine (5-HT), and interleukin-6 (IL-6) were measured using enzyme linked immunosorbent assay. Finally, we screened potential sleep-improving receptors of DOE using polymerase chain reaction (PCR) array and validated the results with quantitative PCR and immunohistochemistry.
RESULTS:
DOE significantly improved rats' sleep and mood, increased the sodium pentobarbital-induced sleep time and sucrose preference index, and reduced autonomic activity times (P<0.05 or P<0.01). DOE also had a good effect on metabolic abnormalities, significantly reducing triglyceride, blood glucose, blood pressure, and blood viscosity indicators (P<0.05 or P<0.01). DOE significantly increased the GABA content in hippocampus and reduced the GA/GABA ratio and IL-6 level (P<0.05 or P<0.01). In addition, DOE improved the pathological changes such as the disorder of cell arrangement in the hippocampus and the decrease of Nissel bodies. Seven differential genes were screened by PCR array, and the GABAA receptors (Gabra5, Gabra6, Gabrq) were selected for verification. The results showed that DOE could up-regulate their expressions (P<0.05 or P<0.01).
CONCLUSION
DOE demonstrated remarkable potential for improving insomnia, which may be through regulating GABAA receptors expressions and GA/GABA ratio.

Intervertebral disc degeneration (IDD) is largely attributed to impaired endogenous repair. Nucleus pulposus-derived stem cells (NPSCs) senescence leads to endogenous repair failure. Small extracellular vesicles/exosomes derived from mesenchymal stem cells (mExo) have shown great therapeutic potential in IDD, while whether mExo could alleviate NPSCs senescence and its mechanisms remained unknown. We established a compression-induced NPSCs senescence model and rat IDD models to evaluate the therapeutic efficiency of mExo and investigate the mechanisms. We found that mExo significantly alleviated NPSCs senescence and promoted disc regeneration while knocking down thioredoxin (TXN) impaired the protective effects of mExo. TXN was bound to various endosomal sorting complex required for transport (ESCRT) proteins. Autocrine motility factor receptor (AMFR) mediated TXN K63 ubiquitination to promote the binding of TXN on ESCRT proteins and sorting of TXN into mExo. Knocking down exosomal TXN inhibited the transcriptional activity of nuclear factor erythroid 2-related factor 2 (NRF2) and activator protein 1 (AP-1). NRF2 and AP-1 inhibition reduced endogenous TXN production that was promoted by exosomal TXN. Inhibition of NRF2 in vivo diminished the anti-senescence and regenerative effects of mExo. Conclusively, AMFR-mediated TXN ubiquitination promoted the sorting of TXN into mExo, allowing exosomal TXN to promote endogenous TXN production in NPSCs via TXN/NRF2/AP-1 feed-forward circuit to alleviate NPSCs senescence and disc degeneration.
