ObjectiveTo decipher the mechanism by which Zuoguiwan (ZGW) treat hyperthyroidism in rats with kidney-Yin deficiency based on the dopamine receptor D4 (DRD4)/nicotinamide adenine dinucleotide phosphate (NADPH) oxidase 4 (NOX4) signaling pathway. MethodsThe rat model of kidney-Yin deficiency was induced by unilateral intramuscular injection of dexamethasone (0.35 mg·kg-1). After successful modeling, the rats were randomized into model, methimazole (positive control, 5 mg·kg-1), low-, medium-, and high-dose (1.85, 3.70, 7.40 g·kg-1, respectively) ZGW, and normal control groups. After 21 days of continuous gavage, the behavioral indexes and body weight changes of rats were evaluated. The pathological changes of the renal tissue were observed by hematoxylin-eosin staining. The serum levels of thyroid hormones [triiodothyronine (T3), thyroxine (T4), thyroid-stimulating hormone (TSH)], renal function indexes [serum creatine (Scr) and blood urea nitrogen (BUN)], energy metabolism markers [cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP)], and oxidative stress-related factors [superoxide dismutase (SOD), malondialdehyde (MDA), and NADPH)] were measured by enzyme-linked immunosorbent assay (ELISA). Western blot was employed to analyze the expression of DRD4, NOX4, mitochondrial respiratory chain complex proteins [NADH:ubiquinone oxidoreductase subunit S4 (NDUFS4) and cytochrome C oxidase subunit 4 (COX4)], and inflammation-related protein [tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), p38 mitogen-activated protein kinase (MAPK)] pathway in the renal tissue. ResultsCompared with the normal group, the model group showed mental malaise, body weight decreases (P<0.01), inflammatory cell infiltration in the renal tissue, a few residual parotid glands in the thyroid, elevations in serum levels of T3, T4, Scr, BUN, cAMP, cAMP/cGMP, MDA, and NADPH (P<0.01), down-regulation in protein levels of TSH, SOD, and DRD4 (P<0.05, P<0.01), and up-regulation in expression of NOX4, p-p38 MAPK/p38 MAPK, and inflammatory factors (P<0.01). Compared with the model group, ZGW increased the body weight (P<0.05, P<0.01), reduced the infiltration of renal interstitial inflammatory cells, restored the thyroid structure and follicle size, lowered the serum levels of T3, T4, Scr, BUN, cAMP, cAMP/cGMP, MDA and NADPH (P<0.05, P<0.01), up-regulated the expression of TSH, SOD and DRD4 (P<0.05, P<0.01), and down-regulated the expression of NOX4, p-p38 MAPK/p38 MAPK, and inflammatory factors (P<0.05, P<0.01). Moreover, high-dose ZGW outperformed methimazole (P<0.05). ConclusionBy activating DRD4, ZGW can inhibit the expression of NOX4 mediated by the p38 MAPK pathway, reduce oxidative stress and inflammatory response, thereby ameliorating the pathological state of hyperthyroidism due to kidney-Yin deficiency. This study provides new molecular mechanism support for the clinical application of ZGW.

ObjectiveTo systematically compare the differential regulation of the maternal-fetal interface cell lineages and communication networks in the CBA/J×DBA/2 mouse model of recurrent pregnancy loss (RPL) by the two classic therapeutic methods-tonifying the kidney to stabilize the fetus and invigorating the spleen to stabilize the fetus (Shoutai Wan, Juyuan Jian)-of traditional Chinese medicine (TCM) at the single-cell resolution and clarify their modern scientific connotations. MethodsFemale non-pregnant CBA/J mice were caged with male BALB/c (blank group) and DBA/2 (modeling group) mice separately. Pregnant mice in the modeling group were randomly grouped as follows: high/low-dose Shoutai Wan, high/low-dose Juyuan Jian, model (RPL), and positive control (dydrogesterone), with 10 mice in each group. Starting from the day after the detection of the vaginal plug, mice were administrated with drugs or an equal volume of normal saline by gavage for 10 consecutive days. After the intervention, the following indicators were measured. ① Macroscopic evaluation: general conditions, uterine wet weight, embryo loss rate, four coagulation parameters [prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB), and thrombin time (TT)], and peripheral blood estradiol (E2) and progesterone (Pg) levels. The decidua with embryos was stained with hematoxylin-eosin (HE) and evaluated by transmission electron microscopy (TEM). The expression of B-cell lymphoma-2 (Bcl-2), vascular endothelial growth factor (VEGF), angiotensin Ⅱ (AngⅡ), matrix metalloproteinase-2 (MMP-2), interleukin-6 (IL-6), leukemia inhibitory factor (LIF), CXC chemokine ligand 12 (CXCL12), and microtubule-associated protein 1 light chain 3 homolog (LC3)Ⅰ/Ⅱ was quantified by Western blot. ② Mechanism analysis at the single-cell level: The decidua with embryos from the blank, model, high-dose Shoutai Wan, and high-dose Juyuan Jian groups (6 mice per group, with 3 single-cell samples per group, totaling 24 mice) were analyzed by the BD Rhapsody™ platform, and the whole-cell atlas was drawn by uniform manifold approximation and projection (UMAP) dimensionality reduction clustering combined with the single-cell mouse cell atlas (scMCA). The differentially expressed genes (DEGs) and cell interaction networks were analyzed via Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and CellChat, and the protein-protein interaction (PPI) map of subtype cells was constructed. The CytoTRACE pseudo-temporal analysis was performed to explore the developmental trajectories of core immune cells (natural killer cells, NK cells) from maternal and fetal sources. Results① Pathological and Western blot results indicated that compared with the blank group, the RPL group showed an increase in the embryo loss rate (P<0.01), down-regulated expression of Bcl-2, LIF, MMP-2, and Vegf in the decidua with embryos (P<0.05), up-regulated protein levels of CXCL-12, AngⅡ, and IL-6 (P<0.05), blocked angiogenesis, apoptosis-inflammation imbalance, and coagulation dysfunction. Both prescriptions dose-dependently reduced the abortion rate and restored the angiogenesis-inflammation balance, and Shoutai pill showed superior performance in restoring the E2 level to the Pg level (P<0.05). ② Single-cell transcriptome analysis indicated that compared with the blank group, the RPL group showed differences in multiple key cell populations such as decidual cells, trophoblast cells, endothelial cells, erythroblasts, NK cells, and macrophages at the maternal-fetal interface. Immunity and angiogenesis were the key links in RPL. Compared with the RPL group, high-dose Shoutai Wan reversed the changes of NK cells in the embryonic layer (upregulating the mRNA levels of 17 genes and downregulating the mRNA levels of 29 genes) and macrophages (upregulating the mRNA levels of 117 genes and downregulating the mRNA levels of 53 genes) through the regulation of gene expression. High-dose Shoutai pill regulated the immune cells to affect unfolded proteins, cell adhesion, and programmed cell death, thereby promoting decidualization and angiogenesis and modulating embryo-membrane development. High-dose Juyuan Jian regulated the key subgroups of NK cells (up-regulating the mRNA levels of 9 genes and down-regulating the mRNA levels of 17 genes) and macrophages (up-regulating the mRNA levels of 110 genes and down-regulating the mRNA levels of 81 genes), which affected decidual inflammation and apoptosis and intervened in glycolysis. ③ The pseudo-temporal analysis and communication network indicated that the communication frequency of the RPL group decreased. High-dose Shoutai Wan restored maternal-fetal tolerance through pathways such as NKG2D, CDH5, GDF, and FASLG. High-dose Juyuan Jian enhanced the IL-6/LIFR/JAK/signal transducer and activator of transcription 3 (STAT3) and desmosome/SEMA6/tumor necrosis factor-like weak inducer of apoptosis (TWEAK) signaling to improve endometrial receptivity. The RPL group showed an increased proportion of toxic dNK7, a decreased proportion of reparative dNK4, and blocked embryo fNK1. High-dose Shoutai Wan down-regulated dNK7 and up-regulated dNK4. High-dose Juyuan Jian inhibited the terminal differentiation of dNK7 and up-regulated LILRB1, thus restoring the balance of cytotoxicity and repair. ConclusionBoth the kidney-tonifying and spleen-invigorating methods are effective in treating RPL. NK and macrophages are the key immune cells in the interaction between the embryo and the membrane. The kidney-tonifying method (Shoutai Wan) has an advantage in regulating the phenotypes of unfolded protein, cell adhesion, and programmed cell death, and shows expression characteristics closer to the physiological state in the regulation of NKG2D and CDH5 signals. The spleen-invigorating method (Juyuan Jian) has an advantage in regulating epithelial-mesenchymal transition (EMT), angiogenesis, and glycolysis and shows higher communication intensity in the IL-6 and LIFR pathways.

OBJECTIVE To provide references for the accurate identification and management of immune-related cutaneous adverse events (irCAEs) caused by durvalumab, and ensuring safe clinical drug use. METHODS Clinical pharmacists participated in the diagnosis and treatment process of a patient with gallbladder cancer who developed irCAEs caused by durvalumab. The clinical pharmacists systematically reviewed the patient’s past medical history and medication history, and assisted physicians in assessing the association between adverse drug reactions and administered drugs. Meanwhile, the clinical pharmacists conducted a graded assessment of the adverse reaction, proposed recommendations such as discontinuing durvalumab and adjusting the administration regimen of glucocorticoids, assisted physicians in restarting immunotherapy, and carried out medication education and other pharmaceutical care. RESULTS The occurrence of irCAEs in this patient was “highly likely” related to durvalumab and was classified as severe. The physicians adopted the clinical pharmacist’s opinion, and after symptomatic treatment, the patient’s skin symptoms improved, and discharged with medication. After the completion of glucocorticoid therapy for the patient, the physician restarted immunotherapy with tislelizumab, and no related adverse reactions occurred again in the patient. CONCLUSIONS Durvalumab can cause irCAEs such as severe skin maculopapular rash. In clinical practice, it is crucial to promptly identify and discontinue suspicious drugs, immediately implement effective symptomatic treatment measures, and actively resume immunotherapy to ensure the continuity and safety of the patient’s treatment.

Objective:
To investigate the current status of benefit finding among young and middle-aged patients with type 2 diabetes mellitus (T2DM) and analyze its influencing factors, so as to provide a reference for improving the level of benefit finding in this population.
Methods:
From November 2022 to May 2023, young and middle-aged patients with T2DM aged 18-59 years hospitalized in the endocrinology departments of 2 tertiary hospitals in Hengyang City, Hunan Province were selected as survey subjects by a convenience sampling method. Basic demographic information was collected using a general questionnaire survey. Benefit finding, resourcefulness, and stigma were evaluated using the Benefit Finding Scale, the Chinese Version of the Resourcefulness Scale, and the Type 2 Diabetes Stigma Assessment Scale, respectively. A multiple linear regression model was used to analyze the influencing factors of benefit finding among young and middle-aged patients with T2DM.
Results:
A total of 305 young and middle-aged patients with T2DM were investigated, including 222 males (72.79%) and 83 females (27.21%). There were 231 cases aged 45-59 years, accounting for 75.74%. The scores for benefit finding, resourcefulness, and stigma were (42.86±6.06), (75.12±11.30), and (41.20±10.10), respectively. Multiple linear regression analysis showed that young and middle-aged patients with T2DM who were male (β′=0.088), aged 18-<45 years (β′=0.083), absence of diabetes complications (β′=0.124), and had higher resourcefulness scores (β′=0.679) had higher levels of benefit finding, while patients with higher stigma scores (β′=-0.097) had lower levels of benefit finding.
Conclusion
The level of benefit finding among young and middle-aged patients with T2DM was moderate, and was related to gender, age, diabetes complications, resourcefulness, and stigma.

Objective:
To analyze the prevalence status and clustering patterns of risk factors for chronic diseases among adult residents in Rui' an City, Zhejiang Province, so as to provide a basis for formulating strategies for the prevention and control of chronic diseases and implementing risk factor interventions.
Methods:
A multi-stage random cluster sampling method was used to select residents aged ≥18 years in 5 townships (sub-districts) of Rui' an City as survey subjects from December 2023 to March 2024. Data on basic information, history of major chronic diseases, lifestyle behaviors, height, weight, and blood biochemical indicators were collected through questionnaire surveys, physical examinations, and laboratory tests. Descriptive analysis was used to analyze the prevalence status of 5 risk factors for chronic diseases. K-means clustering analysis was used to analyze clustering patterns.
Results:
A total of 3 060 people were surveyed, including 1 476 males, accounting for 48.24%, and 1 584 females, accounting for 51.76%. The median age was 49.00 (interquartile range, 25.00) years. There were 1 275 cases (41.67%) of hypertension, 462 cases (15.10%) of diabetes, and 1 460 cases (47.71%) of dyslipidemia. Insufficient fruit and vegetable intake, excessive salt intake, overweight and obesity, excessive red meat intake, and smoking involved 2 201, 1 878, 1 541, 1 337, and 571 people, with prevalences of 71.93%, 61.37%, 50.36%, 43.69%, and 18.66%, respectively. K-means clustering analysis identified 4 clustering patterns: smoking-insufficient fruit and vegetable intake type (249 people, accounting for 8.20%), low intake type (1 421 people, accounting for 46.75%). high red meat type (245 people, accounting for 8.07%), and high BMI-high salt type (1 118 people, accounting for 36.96%). The prevalences of hypertension and diabetes were higher in adult residents of the high BMI-high salt type, at 56.53% and 20.30%, respectively. The prevalence of dyslipidemia was higher in adult residents of the smoking-insufficient fruit and vegetable intake type, at 59.44%.
Conclusions
The prevalence of insufficient fruit and vegetable intake among adult residents in Rui' an City is relatively high. The clustering pattern of chronic disease risk factors is dominated by the low intake type. The prevalence of chronic diseases is higher in adult residents of the high BMI-high salt type and smoking-insufficient fruit and vegetable intake type. It is suggested to carry out health education and collaborative intervention of risk factors for different risk groups.

OBJECTIVE To investigate the potential mechanism by which Juanxiao decoction improves bronchial asthma (hereinafter referred to as “asthma”) based on the nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 (NLRP3) inflammasome signaling pathway. METHODS Female SD rats were randomly assigned to normal group, model group and Juanxiao decoction low-, medium- and high-dose groups (0.36, 0.72 and 1.44 g/kg, calculated based on crude drug weight), as well as positive control group (Dexamethasone acetate tablets, 0.2 mg/kg), with 10 rats in each group. Except for the normal group, asthma models were established in the remaining groups via intraperitoneal injection of ovalbumin combined with aluminum hydroxide, followed by nebulized inhalation of ovalbumin. On day 14 of the experiment, rats in each group received intragastric administration of the corresponding solution or normal saline, once a day, for 7 consecutive days. Following the final administration, the following parameters were measured in each group: lung function indexes (forced vital capacity, forced expiratory volume in 0.3 second, peak expiratory flow), serum levels of inflammatory markers (interleukin-1β, interleukin- 18), and the percentages of inflammatory cells (lymphocytes, eosinophils, neutrophils) in bronchoalveolar lavage fluid. Histopathological changes in lung tissue were observed, and the protein and mRNA expressions of nuclear factor-kappa B (NF- κB), NLRP3 and caspase-1 in lung tissue were detected. RESULTS Compared with the normal group, pathological changes such as alveolar wall thickening and inflammatory cell infiltration were observed in rats in the model group. All pulmonary function indicators were significantly reduced in rats in the model group and the administration groups. The levels of inflammatory markers, the percentages of inflammatory cells, and the protein and mRNA expressions of NF-κB, NLRP3 and caspase-1 were significantly elevated or up-regulated (P<0.05). Compared with the model group, pathological changes in rats in each dosage group of Juanxiao decoction were significantly alleviated, and all quantitative indicators showed dose-dependent improvements (P<0.05). CONCLUSIONS Juanxiao decoction can reduce airway inflammatory responses in asthmatic rats, alleviate lung function impairment, and improve pathological changes such as inflammatory cell infiltration. Those effects may be related to the inhibition of the NLRP3 inflammasome signaling pathway.

Ulcerative colitis(UC) is a chronic non-specific inflammatory bowel disease characterized by inflammation and ulceration of the colonic mucosa and submucosa, and its complex pathogenesis involves immune abnormality, oxidative stress and other factors. The nuclear transcription factor E2-related factor 2(Nrf2), encoded by the Nfe212 gene, plays a central role in antioxidant responses. It not only activates various antioxidant response elements such as heme oxygenase-1(HO-1) and quinone oxidoreductase 1(NQO1), but also enhances the activity of glutathione-S-transferase(GST) and superoxide dismutase 1(SOD1), effectively eliminating reactive oxygen species(ROS) accumulated in the body, and mitigating oxidative stress-induced damage to intestinal mucosa. In addition, Nrf2 can reduce the release of inflammatory factors and infiltration of immune cells by regulating immune response, cell apoptosis and autophagy pathways, thereby alleviating intestinal inflammation and promoting the repair and regeneration of damaged mucosa. Based on this, this paper reviews the research progress of Chinese materia medica in the prevention and treatment of UC by modulating the Nrf2 signaling pathway. It deeply explores the physiological role of Nrf2, the molecular mechanism of activation, the protective effect in the pathological process of UC, and how active ingredients in Chinese materia medica regulate the Nrf2 signaling pathway through multiple pathways to exert their potential mechanisms. These studies have revealed in depth that Chinese materia medica can effectively combat oxidative stress by regulating the Nrf2 signaling pathway. It can also play a role in anti-inflammatory, promoting autophagy, inhibiting apoptosis, protecting the intestinal mucosal barrier, and promoting intestinal mucosal repair, providing new ideas and methods for the multi-faceted treatment of UC.

ObjectiveTo observe the clinical efficacy and safety of Tangning Tongluo tablets in the treatment of nonproliferative diabetic retinopathy (DR). MethodsFourteen research centers participated in this study, which spanned a time interval from September 2021 to May 2023. A total of 240 patients with nonproliferative DR were included and randomly assigned into an observation group (120 cases) and a control group (120 cases). The observation group was treated with Tangning Tongluo tablets, and the control group with calcium dobesilate capsules. Both groups were treated for 24 consecutive weeks. The vision, DR progression rate, retinal microhemangioma, hemorrhage area, exudation area, glycosylated hemoglobin (HbA1c) level, and TCM syndrome score were assessed before and after treatment, and the safety was observed. ResultsThe vision changed in both groups after treatment (P<0.05), and the observation group showed higher best corrected visual acuity (BCVA) than the control group (P<0.05). The DR progression was slow with similar rates in the two groups. The fundus hemorrhage area and exudation area did not change significantly after treatment in both groups, while the observation group outperformed the control group in reducing the fundus hemorrhage area and exudation area. There was no significant difference in the number of microhemangiomas between the two groups before treatment. After treatment, the number of microhemangiomas decreased in both the observation group (Z=-1.437, P<0.05) and the control group (Z=-2.238, P<0.05), and it showed no significant difference between the two groups. As the treatment time prolonged, the number of microhemangiomas gradually decreased in both groups. There was no significant difference in the HbA1c level between the two groups before treatment. After treatment, the decline in the HbA1c level showed no significant difference between the two groups. The TCM syndrome score did not have a statistically significant difference between the two groups before treatment. After treatment, neither the TCM syndrome score nor the response rate had significant difference between the two groups. With the extension of the treatment time, both groups showed amelioration of TCM syndrome compared with the baseline. ConclusionTangning Tongluo tablets are safe and effective in the treatment of nonproliferative DR, being capable of improving vision and reducing hemorrhage and exudation in the fundus.

ObjectiveBased on ultra performance liquid chromatography-quadrupole-electrostatic field orbital trap high-resolution mass spectrometry(UPLC-Q-Orbitrap-MS), to identify the in vivo and in vitro chemical components of total phenolic acids in Gei Herba(TPAGH), and to clarify the pharmacological effects and potential mechanisms of the effective part in promoting acute wound healing and inhibiting scar formation. MethodsUPLC-Q-Orbitrap-MS was used to identify the chemical components of TPAGH and ingredients absorbed in vivo after topical administration. A total of 120 ICR mice were randomly divided into the model group, recombinant human epidermal growth factor(rhEGF) group(4 mg·kg-1), and low, medium, and high dose groups of TPAGH(3.5, 7, 14 mg·kg-1), with 24 mice in each group. A full-thickness skin excision model was constructed, and each administration group was coated with the drug at the wound site, and the model group was treated with an equal volume of normal saline, the treatment was continued for 30 days, during which 8 mice from each group were sacrificed on days 6, 12, and 30. The healing of the wounds in the mice was observed, and histopathological changes in the skin tissues were dynamically observed by hematoxylin-eosin(HE), Masson, and Sirius red staining, and enzyme-linked immunosorbent assay(ELISA) was used to dynamically measure the contents of interleukin-6(IL-6), tumor necrosis factor-α(TNF-α), vascular endothelial growth factor A(VEGFA), matrix metalloproteinase(MMP)-3 and MMP-9 in skin tissues. Network pharmacology was used to predict the targets related to the promotion of acute wound healing and the inhibition of scar formation by TPAGH, and molecular docking of key components and targets was performed. Gene Ontology(GO) biological process analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis were carried out for the related targets, so as to construct a network diagram of herbal material-compound-target-pathway-pharmacological effect-disease for further exploring its potential mechanisms. ResultsA total of 146 compounds were identified in TPAGH, including 28 phenylpropanoids, 31 tannins, 23 triterpenes, 49 flavonoids, and 15 others, and 16 prototype components were found in the serum of mice. Pharmacodynamic results showed that, compared with the model group, the TPAGH groups showed a significant increase in relative wound healing rate and relative scar inhibition rate(P<0.05), and the number of new capillaries, number of fibroblasts, number of new skin appendages, epidermal regeneration rate, collagen deposition ratio, and Ⅲ/Ⅰ collagen ratio in the tissue were significantly improved(P<0.05, 0.01), the levels of IL-6, TNF-α, MMP-3 and MMP-9 in the skin tissues were reduced to different degrees, while the level of VEGFA was increased. Network pharmacology analysis screened 10 core targets, including tumor protein 53(TP53), sarcoma receptor coactivator(SRC), protein kinase B(Akt)1, signal transducer and activator of transcription 3(STAT3), epidermal growth factor receptor(EGFR) and so on, participating in 75 signaling pathways such as advanced glycation end-products(AGE)-receptor for AGE(AGE/RAGE) signaling pathway, phosphatidylinositol 3-kinase(PI3K)/Akt signaling pathway, mitogen-activated protein kinase(MAPK) signaling pathway. Molecular docking confirmed that the key components genistein, geraniin, and casuariin had good binding ability to TP53, SRC, Akt1, STAT3 and EGFR. ConclusionThis study comprehensively reflects the chemical composition of TPAGH and the absorbed components after topical administration through UPLC-Q-Orbitrap-MS. TPAGH significantly regulates key indicators of skin healing and tissue reconstruction, thereby clarifying its role in promoting acute wound healing and inhibiting scar formation. By combining in vitro and in vivo component identification with network pharmacology, the study explores how key components may bind to targets such as TP53, Akt1 and EGFR, exerting therapeutic effects through related pathways such as immune inflammation and vascular regeneration.

ObjectiveTo establish the self-reported core outcome set (COS) for patients with an example of a community study on heat-sensitive moxibustion for primary hypertension (PH), to provide a reference for the selection of effectiveness evaluation indicators in community study on heat-sensitive moxibustion. MethodsA systematic literature search was conducted to collect outcomes used in randomized controlled trials and systematic review of heat-sensitive moxibustion for PH (Jan 2021), and additional outcomes were added through patient and expert questionnaires (Feb 2021) to create a pool of outcome entries. A multidisciplinary expert Delphi survey was conducted to screen outcomes applicable to patient self-reporting (Apr 2021), and the importance of outcome indicators was rated on a 5-Point Likert Scale. Finally, patient self-reported COS was determined through a consensus conference (June 2021). ResultsA pool of patient self-reported indicators in the community study of heat-sensitive moxibustion treatment for PH was generated by standardizing and combining the outcome indicators based on the results of the literature search and the questionnaire survey, which consisted of totally 100 measurement tools or contents, excluding 51 indicators or measurement tools required measurement by specialized physicians or hospital equipment, and 49 items were retained to enter the initial list of indicator entries. For the first round of Delphi survey, the mean score for expert familiarity was 0.819, the mean score for basis of judgment was 0.710, and the expert authority coefficient was 0.765, with a total of 21 indicator measurement tools or contents deleted (significance score ≤ 75 or coefficient of variation > 0.25), 28 retained, and 3 new expert-added indicator entries added. In the second round of Delphi survey, the average score for expert familiarity was 0.859, the average score for basis for judgment was 0.763, and the expert authority coefficient was 0.811, with a total of 11 indicator measurement tools or contents deleted and 20 retained involving 5 domains. Following an expert consensus meeting, 8 outcome indicators were finalized for inclusion in the patient self-reported COS, including 6 indicators of effectiveness evaluation such as quality-of-life scores, blood pressure, traditional Chinese medicine symptom scores, cost-benefit, cardiovascular and cerebrovascular events, and adverse reactions/events, and 2 indicators of factors influencing effectiveness such as sensation of heat-sensitive moxibustion, and adherence. ConclusionIn this study, we initially established a criteria for evaluating the effectiveness in the community study on heat-sensitive moxibustion by constructing patient self-reported COS in the community study on heat-sensitive moxibustion for PH, which can provide a scientific research paradigm for the subsequent development of the community study on heat-sensitive moxibustion.
