ObjectiveTo analyze the differences in color, odor and volatile components of Citri Reticulatae Pericarpium(CRP) before and after being stir-fried with Halloysitum Rubrum, and to explore the material basis of enhancing the effect of strengthening spleen after processing and the scientific connotation of decoction pieces processed with Halloysitum Rubrum as the auxiliary material. MethodsThe volatile components of the samples before and after processing were identified and relatively quantified by headspace gas chromatography-mass spectrometry(HS-GC-MS), and the volatile components were analyzed by principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA). According to the principle of variable importance in the projection(VIP) value>1.5, volatile differential components before and after processing were screened. And combined with intelligent sensory technologies such as colorimeter and electronic nose, the chroma and odor information of CRP before and after being stir-fried with Halloysitum Rubrum were identified. Pearson correlation analysis was used to explore the correlation between volatile differential components and chroma values. ResultsA total of 112 volatile components were identified from CRP and CRP stir-fried with Halloysitum Rubrum, of which 84 were from CRP and 97 were from CRP stir-fried with Halloysitum Rubrum. And 7 differential components were selected, including α-pinene, β-myrcene, linalool, sabinene, ocimene isomer mixture, A-ocimene, and δ-elemene. After being processed with Halloysitum Rubrum, the brightness value(L*), yellow-blue value(b*) and total chromatic value(E*ab) of CRP were decreased(P<0.01), and red-green value(a*) was increased(P<0.01), the response values of S4, S5, S10 and S13 sensors were significantly increased(P<0.05), and the response values of S3 and S8 sensors were significantly decreased(P<0.05). Correlation analysis showed that α-pinene and β-myrcene were negatively correlated with L* and E*ab, but positively correlated with a*. Sabinene was positively correlated with L* and E*ab. Linalool was positively correlated with L* and E*ab, and negatively correlated with a*. The ocimene isomer mixture was positively correlated with the L*. ConclusionAfter being processed with Halloysitum Rubrum, the appearance color, odor and volatile components of CRP change significantly, and α-pinene, β-myrcene, sabinene, linalool and A-ocimene are the characteristic volatile components before and after processing, which can provide references for the quality evaluation and clinical application of CRP and its processed products.

Objective To investigate the effects of cucurbitacin B (CucB) on alleviating skin lesions and inflammation in psoriasis mice via the cGAS-STING signaling pathway. Methods The expression of genes associated with the cGAS-STING signaling pathway in psoriatic lesions and non-lesional skin was analyzed, and hallmark gene set enrichment analysis was performed. The cytotoxicity of CucB on BMDMs was evaluated using the CCK-8 assay. The expression levels of genes and proteins related to the cGAS-STING signaling pathway, along with the secretion of inflammatory cytokines, were measured at different concentrations of CucB using quantitative PCR, Western blotting, and ELISA. Imiquimod-induced psoriasis BALB/c mice were divided into four groups: normal group, model group, low-dose CucB group [0.1 mg/ (kg.d)], and high-dose CucB group [0.4 mg/ (kg.d)], with five mice per group. PASI scoring was performed to assess the severity of psoriasis after 6 days of treatment, and HE staining was conducted to observe pathological damage. Meanwhile, the mRNA levels of inflammatory cytokines and their secretion were detected by qPCR and ELISA. Results Most cGAS-STING signaling-related genes were upregulated in lesional skin of psoriasis patients, and the hallmark gene set enrichment analysis revealed that the most significantly upregulated genes were primarily associated with immune response signaling pathways. CucB inhibited dsDNA-induced phosphorylation of interferon regulatory factor 3 (IRF3) and STING proteins in both bone-marrow derived macrophages(BMDMs) and THP-1 cells. CucB also suppressed dsDNA-induced mRNA expression of IFNB1, TNF, IFIT1, CXCL10, ISG15, and reduced the secretion of cytokines such as IFN-β, IL-1β, and TNF-α in THP-1 cells. In the imiquimod-induced psoriasis mouse model, CucB treatment reduced psoriatic symptoms, alleviated skin lesions, and attenuated inflammation. ELISA and qPCR results showed that CucB significantly reduced serum secretion levels of IL-6, TNF-α, and IL-1β, as well as the mRNA levels of IL23A, IL1B, IL6, TNF, and IFNB1. Conclusion CucB inhibits cytoplasmic DNA-induced activationc of the GAS-STING pathway. CucB significantly attenuates skin lesions and inflammation in IMQ-induced psoriatic mice, and the potential molecular mechanism may be related to the down-regulation of the cGAS-STING pathway.

Hypertrophic scar is a fibrous hyperplastic disorder that arises from skin injuries. The current therapeutic modalities are constrained by the dense and rigid scar tissue which impedes effective drug delivery. Additionally, insufficient autophagic activity in fibroblasts hinders their apoptosis, leading to excessive matrix deposition. Here, we developed an active microneedle (MN) system to overcome these challenges by integrating micromotor-driven drug delivery with autophagy regulation to remodel the scar microenvironment. Specifically, sodium bicarbonate and citric acid were introduced into the MNs as a built-in engine to generate CO2 bubbles, thereby enabling enhanced lateral and vertical drug diffusion into dense scar tissue. The system concurrently encapsulated curcumin (Cur), an autophagy activator, and triamcinolone acetonide (TA), synergistically inducing fibroblast apoptosis by upregulating autophagic activity. In vitro studies demonstrated that active MNs achieved efficient drug penetration within isolated scar tissue. The rabbit hypertrophic scar model revealed that TA-Cur MNs significantly reduced the scar elevation index, suppressed collagen I and transforming growth factor-β1 (TGF-β1) expression, and elevated LC3 protein levels. These findings highlight the potential of the active MN system as an efficacious platform for autonomous augmented drug delivery and autophagy-targeted therapy in fibrotic disorder treatments.

Rice (Oryza sativa L.), as a thermophilic crop, is highly susceptible to cold stress during its growth process. Chilling injury at the plumule stage and seedling stage often affects the morphological development and leads to yield reduction of rice. The exploration and utilization of cold tolerance genes are among the most direct and effective approaches to address cold stress in rice. To identify quantitative trait loci (QTLs) associated with cold tolerance at plumule and seedling stages, in this study, we measured the seedling rates and survived seedling rates of the indica rice cultivar 'HZ', the japonica cultivar 'Nekken2', and their 120 recombinant inbred lines (RILs) under cold stress. A previously constructed high-density genetic linkage map was used for the mapping of the QTLs conferring cold tolerance at the plumule and seedling stages. A total of 4 QTLs for plumule-stage cold tolerance and 9 QTLs for seedling-stage cold tolerance were detected, with the maximum limit of detection reaching 5.20. Notably, a genetically overlapping QTL for both plumule and seedling stages was identified on chromosome 8, spanning a physical interval of 24 432 953-25 295 129 bp. Candidate genes within the detected QTL intervals were screened, and quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to analyze the gene expression during the plumule and seedling stages. The results revealed that LOC_Os03g06570, LOC_Os03g07100, LOC_Os06g08280, LOC_Os08g38440, LOC_Os08g39100, and LOC_Os08g39540 exhibited significantly differential expression between the parental lines. These genes were either significantly downregulated or upregulated under cold stress. Among them, the first three gene (LOC_Os03g06570, LOC_Os03g07100, and LOC_Os06g08280) were hypothesized to be key candidates regulating the cold tolerance of rice seedlings, while the latter three genes (LOC_Os08g38440, LOC_Os08g39100, and LOC_Os08g39540) were identified as comprehensive regulators of cold tolerance during both plumule and seedling stages. These findings lay a foundation for the fine mapping and cloning of cold tolerance genes at the plumule and seedling stages, providing valuable insights for breeding cold-tolerant rice varieties.

ObjectiveTo develop a scientifically rigorous and contextually appropriate instrument for evaluating the health service experience of pulmonary tuberculosis patients in China, to enable systematic assessment of core medical care dimensions, and to provide quantitative evidence for service improvement. MethodsGrounded in the theoretical framework of healthcare accessibility and the clinical care pathway for tuberculosis patients, the tool was developed through a systematic literature review and the Delphi expert consultation method. A multi-stage cluster sampling strategy was employed to survey pulmonary tuberculosis patients who had been receiving treatment for more than two months, aimed to explore the scale’s applicability in real-world settings. Reliability was assessed using Cronbach’s α and split-half reliability coefficients. Validity was evaluated through content validity, structural validity, convergent validity, and discriminant validity. ResultsThe tool was composed of 21 items across four dimensions: awareness, accessibility, affordability, and acceptability of tuberculosis medical care. It demonstrated a Cronbach’s α coefficient of 0.838 and a split-half reliability coefficient of 0.859. Exploratory factor analyses extracted six factors: satisfaction with healthcare services, supportive role of nurses, affordability of treatment costs, doctor-patient communication, waiting time for medical appointments, and transportation cost. The goodness-of-fit index (GFI) and other indices met the recommended standards, with the loading matrix indicating robust structural validity of the tool. The constructed factor model exhibited satisfactory content validity and discriminant validity. ConclusionThe scale for assessing patients’ experiences with tuberculosis-related medical care developed in this study demonstrates good reliability and validity and serves as a practical tool for evaluating patient experiences of tuberculosis medical care in China.

OBJECTIVE To investigate the improvement effects of 3,5,6,7,8,3′,4′-heptamethoxyflavone (HMF) of Fructus Aurantii on rats with damp blockage of the middle energizer. METHODS The rats were randomly divided into normal group, model group, positive control group (Raceanisodamine tablet, 1 mg/kg), HMF low-dose, medium-dose and high-dose groups (0.3, 0.6, 0.9 mg/kg), with 7 rats in each group. Except for the normal group, the other groups were modeled by internal and external composite factors. After successful modeling, the rats in each group were given the corresponding drug or normal saline, once a day, for 14 days. The general behavioral states such as dietary intake, water intake and mental state of the rats were observed, and the fecal water content rate and saliva flow rate were measured. Hematoxylin-eosin (HE) staining was used to observe the pathological and morphology in gastric and small intestinal tissues of rats. The plasma content of aldosterone was detected, and the expression of aquaporins (AQP3) in the gastric tissue of rats was determined. RESULTS Compared with the normal group, the dietary intake and water intake of the model group rats were significantly decreased (P<0.01), the fecal water content rate, salivary flow rate, plasma content of aldosterone and the expression of AQP3 in gastric tissue were increased significantly (P<0.01). Gastric tissue injury invaded the mucosal muscle layer, resulting in mucosal muscle layer rupture; pathological and morphological changes such as small intestinal villous erosion and glandular structure destruction were observed in the small intestine. Compared with the model group, the dietary intake and water intake of rats were increased in HMF groups; fecal water content rate, salivary flow rate, plasma content of aldosterone, the expression of AQP3 in gastric tissue were decreased, most of the above differences were statistically significant (P<0.05 or P<0.01). The pathological and morphological changes in the gastric and small intestine tissues of rats had been improved to varying degrees. CONCLUSIONS HMF of Fructus Aurantii with dry property HMF could improve the symptoms of rats with damp blockage of middle energizer, the mechanism of which may be associated with reducing the content of plasma aldosterone and down-regulating the expression of gastric AQP3.

In the era of evidence-based medicine, it is necessary to explore the unique advantages of traditional Chinese medicine (TCM) based on standardized technical methods and operating procedures in order to achieve the modernization and internationalization of TCM and benefit all humanity. The proposal of a three-pronged evidence system combining TCM theory, human experience and experimental evidence marks an important progress in the thinking method of the TCM evaluation system. The multi-evidence body integrated through appropriate methods provides a strong support for the clinical guideline recommendations and evidence-based health decision-making in TCM. Based on the current methodological progress of international evidence synthesis and grading, this paper proposes a novel approach for integrating multi-evidence in TCM: the MERGE framework. The aim is to establish a solid foundation for the development of this methodology and provide guidance for the advancement of evidence-based medicine framework in TCM.

Immune checkpoint inhibitors (ICIs) have been approved for the treatment of urothelial carcinoma(UC). However, the use of antibiotics, proton pump inhibitors, corticosteroids, beta-blockers, metformin, and statin concomitant medications in some patients due to complications during the treatment process may affect the clinical efficacy of ICIs through different pathway, making it difficult for patients to derive clinical benefit or making it more likely to develop drug resistance. In this paper, we present a review of the effects of the above concomitant drugs on ICIs in the treatment of patients with advanced UC, with a view to provide reference for the application of individualized treatment strategies of ICIs in patients with advanced UC.

Objective To explore the influencing factors of visual acuity recovery in patients with high myopia after posterior chamber phakic intraocular lens(ICL)implantation.Methods A prospective study was conducted on 210 pa-tients(420 eyes)with high myopia who underwent ICL implantation at the Second Affiliated Hospital of Zhengzhou Univer-sity from May 2021 to March 2023.The patients were divided into a good recovery group[best corrected visual acuity(BC-VA)recovery ≥0.3 D]and a poor recovery group(BCVA recovery<0.3 D)based on their visual acuity recovery status three months after surgery.The baseline data of patients in the two groups were compared,and the factors affecting visual acuity recovery were analyzed using Logistic regression.The receiver operating characteristic(ROC)curve was used to an-alyze the predictive value of the Logistic regression model for poor visual acuity recovery in patients with high myopia after ICL implantation.Results Three months after surgery,149 patients(298 eyes)were in the good recovery group,and 61 patients(122 eyes)were in the poor recovery group.There were no significant differences in gender,age,years of myopi-a,body mass index,and academic performance between the two groups(all P>0.05).The proportions of patients with corneal astigmatism<1.30 D(55.74%),corneal diopter<45 D(59.02%),Pittsburgh Sleep Quality Index(PSQI)<7 points(63.93%),and average central radius of curvature[(7.82±0.27)mm]in the poor recovery group were lower than those in the good recovery group[83.89%,81.88%,85.91%,and(7.90±0.24)mm,respectively].The central flat me-ridian curvature(k1)of the anterior corneal surface[(43.27±1.43)D],steep meridian curvature(k2)of the anterior corneal surface[(44.84±1.53)D],and arch height[(628.49±67.28)μm]in the poor recovery group were higher than those in the good recovery group[(42.73±1.42)D,(44.12±1.47)D],and[(417.56±80.14)pm],with significant differences(all P<0.05).Logistic regression analysis showed that corneal astigmatism,corneal diopter,k1,k2,arch height,and PSQI score were independent influencing factors of poor visual acuity recovery after ICL implantation in pa-tients with high myopia(all P<0.05).ROC curve analysis showed that the area under the ROC curve for predicting poor visual acuity recovery after ICL implantation in patients with high myopia by Logistic regression model was 0.938(95%CI:0.896-0.966),the sensitivity was 83.61%,and the specificity was 91.95%(P<0.05).Conclusion The visual acuity recovery after ICL implantation in patients with high myopia is affected by corneal astigmatism,corneal diopter,k1,k2,arch height,and PSQI score.The Logistic regression model based on these factors has high predictive value for visual acui-ty recovery after ICL implantation.
