ObjectiveThis study aims to systematically analyze the blood-absorbed components and metabolic profiles of Xiebaisan(XBS) in normal and chronic bronchitis (CB) mice using ultra performance liquid chromatography-quadrupole-electrostatic field orbitrap high resolution mass spectrometry(UPLC-Q-Exactive Orbitrap MS), while comparing differences between the two states. MethodsThirty female BABL/c mice were randomly divided into the normal group, the normal drug administration group, the CB group, the CB drug administration group and the dexamethasone group, with 6 mice in each group. The CB mouse model was established by inducing with ovalbumin (OVA). The mice in the normal drug administration group and the CB drug administration group started to be gavaged with XBS(13.2 g·kg-1) from the 21st day, and the dexamethasone group mice were simultaneously gavaged with dexamethasone (0.5 mg·kg-1) until the end of the 35th day of the experiment. Subsequently, serum samples were collected and evaluated for their efficacy, based on the pharmacological evaluation indicators, to determine the efficacy of XBS in treating CB. Then the UPLC-Q-Exactive Orbitrap MS was employed to identify and analyze the chemical constituents, blood-absorbed components, and metabolites of XBS. Chemometric analysis was conducted to reveal metabolic profile differences under "dual states". Concurrently, Real-time PCR technology was utilized to detect the expression levels of key liver metabolic enzymes CYP2E1, CYP3A1, UGT1A1, and UGT1A6. ResultsA total of 28 prototype components and 158 metabolites (including 48 phase Ⅰ metabolites and 110 phase Ⅱ metabolites) of XBS were unambiguously identified in the serum of normal mice. Additionally, a comprehensive characterization was performed on a total of 32 prototype components and 178 metabolites (including 50 phase Ⅰ metabolites and 128 phase Ⅱ metabolites) of XBS in the serum of CB mice. Among them, 27 prototype components were detected in both states, including 12 flavonoids, 2 alkaloids, 3 triterpenes, 4 organic acids, 3 amides, 1 stilbene and 2 other compounds. The chemometrics analysis revealed no significant difference in the prototype components and metabolites of XBS between normal and CB mice; however, there was a significant increase in the in-vivo exposure of XBS in CB mice. Compared to normal mice, the levels of phase Ⅰ metabolites such as oxidation, reduction and methylation of blood components of XBS as well as phase Ⅱ metabolites of glucuronidation showed significant changes in CB mice. Real-time PCR further confirmed that these alterations were attributed to the upregulation of CYP2E1 (P<0.05), CYP3A1 (P>0.05), UGT1A1 (P<0.01) and UGT1A6 (P<0.01) enzymes expression in the liver of CB mice. ConclusionThis study elucidated the disparities in the levels of the blood-absorbed components and metabolic profiles of XBS in normal and CB mice, especially in oxidation, reduction, methylation in phase Ⅰ metabolism and glucoaldehyde acidification in phase Ⅱ metabolism. And there are related to the differences in the expression levels of phase Ⅰ and phase Ⅱ metabolic enzymes CYP2E1, CYP3A1, UGT1A1 and UGT1A6 in the liver.

ObjectiveTo investigate the imaging features of calcium salt deposition and serological markers in patients with alveolar echinococcosis through a retrospective analysis, as well as independent risk factors for the degree of calcium salt deposition in lesions, and to provide a basis for assessing disease process. MethodsA retrospective analysis was performed for the imaging and clinical data of 107 patients with alveolar echinococcosis who were admitted to The First Affiliated Hospital of Shihezi University from December 2023 to June 2025, and according to the volume of calcium salt deposition, they were divided into non-deposition group with 16 patients, mild deposition group with 52 patients, moderate deposition group with 16 patients, and severe deposition group with 23 patients. A one-way analysis of variance or the Kruskal-Wallis H test was used for comparison of continuous data between groups, and the χ2 test or Fisher’s exact test was used for comparison of categorical data between groups. The four groups were further combined into the low deposition group (no/mild deposition) and the high deposition group (moderate/severe deposition). A binary logistic regression analysis was used to investigate the independent influencing factors for calcium salt deposition, and a predictive model was established. The receiver operating characteristic (ROC) curve was used to assess the predictive performance of the model, and the Bootstrap method was used for internal validation. ResultsThere were significant differences between the four groups in sex distribution, involvement of other sites, white blood cell count, lymphocyte percentage, fibrinogen, uric acid, sodium ion, chloride ion, and calcium ion (all P<0.05). The univariate analysis showed that there were significant differences between the four groups in sex, involvement of other sites, white blood cell count, lymphocyte percentage, fibrinogen, alanine aminotransferase, albumin, creatinine, uric acid, sodium ion, chloride ion, and calcium ion (all P<0.1). The multi-collinearity diagnosis showed that the VIF values for all continuous variables ranged from 1.104 to 1.760, suggesting that collinearity did not affect modeling. An ordinal logistic regression model was established based on sex, involvement of other sites, calcium ion, lymphocyte percentage, and uric acid. The multivariate analysis showed that lymphocyte percentage (odds ratio [OR]=1.106, 95% confidence interval [CI]: 1.041 — 1.174, P=0.001) and blood calcium level (OR=0.005, 95%CI: 0.000 —0.230, P=0.007) were independent influencing factors for the degree of calcium salt deposition. The regression equation was established as Logit(P)=8.231 + 0.100 × lymphocyte percentage -5.344 × calcium ion. The ROC curve analysis showed that the model had an area under the ROC curve of 0.716, with a Youden index of 0.353, a sensitivity of 1.000, and a specificity of 0.353. The Hosmer-Lemeshow test showed that the model had poor calibration (χ2=20.688, P=0.008). The Bootstrap method with 1000 repeated samples showed that the estimated values of lymphocyte percentage (OR=1.106, 95%CI: 1.049 — 1.186, P=0.002) and calcium ion (OR=0.005, 95%CI: 0.000 — 0.214, P=0.010) were consistent with the original model, and the confidence intervals did not include 1, which further supported the reliability of the model. ConclusionBoth lymphocyte percentage and blood calcium level are independent influencing factors for calcium salt deposition in alveolar echinococcosis, and the degree of calcium salt deposition in alveolar echinococcosis lesions increases with the reduction in blood calcium level and the increase in lymphocyte percentage.

OBJECTIVE:
To observe the effect of heat-sensitive moxibustion at "Feishu" (BL13) on immunoinflammatory response in rats with allergic rhinitis (AR) based on phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway, so as to explore its underlying mechanism.
METHODS:
Thirty-two male SD rats were randomly divided into a blank group (6 rats) and a modeling group (26 rats). In the modeling group, AR model was prepared using systemic and local attack sensitization method with ovalbumin. The successfully-modeled rats were randomized into a model group (6 rats), a medication group (6 rats) and a moxibustion group (14 rats). In the moxibustion group, the suspending moxibustion was operated at bilateral "Feishu" (BL13), 40 min each time, once daily, for 21 consecutive days; during which, the temperature of the body and tail was recorded. During intervention, if the temperature of the body and tail increased by >1 ℃, the heat-sensitive reaction at the point was determined in the rats of the moxibustion group, and these rats were collected in a heat-sensitive moxibustion group (8 rats involved and 6 rats of them were randomly collected to ensure the sample-size consistency); and those without heat-sensitive moxibustion reaction were assigned to a traditional moxibustion group (6 rats). In the medication group, fluticasone propionate nasal spray was applied, 8 μL on each side, once daily and for 21 days. The behavioral score for AR symptoms after modeling and intervention, and the content of serum immunoglobulin E (IgE) after modeling were observed. After intervention, the histological morphology of the nasal mucosa was observed using HE staining, the positive expression of thymic stromal lymphopoietin (TSLP) in the nasal mucosa was detected using immunohistochemistry, the levels of IgE, interleukin (IL)-4, IL-5, IL-13 and interferon-γ (IFN-γ) were detected by ELISA, and the protein expression of the member 4 of tumor necrosis factor receptor superfamily (OX40), phosphorylated protein kinase B (p-AKT), phosphorylated phosphatidylinositol 3-kinase (p-PI3K) in nasal mucosa was detected by Western blotting.
RESULTS:
After modeling, the behavioral score of AR symptoms and serum IgE level in the modeling group were higher than those of the blank group (P<0.01), suggesting the success of AR modeling. After intervention, compared with the blank group, the behavioral score of AR symptoms was increased (P<0.01);the nasal mucosa structure was disordered, the inflammatory infiltration was severe; the positive expression of TSLP in the nasal mucosa increased (P<0.01), the levels of serum IgE, IL-4, IL-5, and IL-13 elevated (P<0.01), and the level of IFN-γ decreased (P<0.01); and the protein expression of OX40, p-AKT, and p-PI3K in the nasal mucosa increased (P<0.05) in the model group. Compared with the model group, the behavioral score of AR symptoms was reduced (P<0.01); the nasal mucosa structure, inflammatory infiltration, and vascular dilation were ameliorated to varying degrees; the positive expression of TSLP in the nasal mucosa decreased (P<0.01); the content of serum IgE, IL-4, IL-5, and IL-13 decreased (P<0.05), and that of IFN-γ increased (P<0.05) in the medication, traditional moxibustion, and heat-sensitive moxibustion groups. Compared with the model group, the protein expression of p-AKT was reduced in the medication and traditional moxibustion groups (P<0.05), the protein expression of OX40, p-AKT, and p-PI3K in the nasal mucosa decreased in the heat-sensitive moxibustion group (P<0.05). When compared with the medication group, the positive expression of TSLP in the nasal mucosa was reduced (P<0.05) in the heat-sensitive moxibustion group. In comparison with the traditional moxibustion group, the content of serum IL-13 was reduced and the content of IFN-γ elevated in the heat-sensitive moxibustion and the medication groups (P<0.05), the protein expression of p-PI3K reduced in the medication group (P<0.05), and the positive expression of TSLP and the protein expression of OX40 and p-PI3K in the nasal mucosa were reduced in the heat-sensitive moxibustion group (P<0.05).
CONCLUSION
Heat-sensitive moxibustion at "Feishu" (BL13) can alleviate the symptoms of AR rats, ameliorate the inflammatory infiltration and telangiectasia of nasal mucosa, and inhibit immunoinflammatory response, which may be obtained by regulating PI3K/AKT signal pathway.

Based on his extensive clinical experience and the team's mechanistic research, Professor XU Nenggui has proposed the academic concept that "the governor vessel governs the brain and treats cerebral viscus diseases", and established a novel acupuncture approach for encephalopathy treatment centered on the integrated theory of "governor vessel-brain-mind", and developed a staged acupuncture protocol of "governor vessel regulating spirit" for ischemic stroke. This article introduces the academic features of this method in treating post-stroke dysphagia from four aspects: theoretical framework, treatment principles and point selection, mechanistic research, and clinical case studies. In clinical application, the method emphasizes syndrome differentiation based on meridians, harmonization between the conception and governor vessels; precise acupoint selection to treat both form and spirit; stage-specific differentiation with targeted needling. Furthermore, Professor XU integrates basic research with clinical practice, focusing on the neurobiological mechanisms underlying the efficacy of acupuncture in treating post-stroke dysphagia.

BACKGROUND:
The main cause of restenosis after percutaneous transluminal angioplasty (PTA) is the excessive proliferation and migration of vascular smooth muscle cells (VSMCs). Lin28a has been reported to play critical regulatory roles in this process. However, whether CCAAT/enhancer-binding proteins β (C/EBPβ) binds to the Lin28a promoter and drives the progression of restenosis has not been clarified. Therefore, in the present study, we aim to clarify the role of C/EBPβ-Lin28a axis in restenosis.
METHODS:
Restenosis and atherosclerosis rat models of type 2 diabetes ( n = 20, for each group) were established by subjecting to PTA. Subsequently, the difference in DNA methylation status and expression of C/EBPβ between the two groups were assessed. EdU, Transwell, and rescue assays were performed to assess the effect of C/EBPβ on the proliferation and migration of VSMCs. DNA methylation status was further assessed using Methyltarget sequencing. The interaction between Lin28a and ten-eleven translocation 1 (TET1) was analysed using co-immunoprecipitation (Co-IP) assay. Student's t -test and one-way analysis of variance were used for statistical analysis.
RESULTS:
C/EBPβ expression was upregulated and accompanied by hypomethylation of its promoter in restenosis when compared with atherosclerosis. In vitroC/EBPβ overexpression facilitated the proliferation and migration of VSMCs and was associated with increased Lin28a expression. Conversely, C/EBPβ knockdown resulted in the opposite effects. Chromatin immunoprecipitation assays further demonstrated that C/EBPβ could directly bind to Lin28a promoter. Increased C/EBPβ expression and enhanced proliferation and migration of VSMCs were observed after decitabine treatment. Further, mechanical stretch promoted C/EBPβ and Lin28a expression accompanied by C/EBPβ hypomethylation. Additionally, Lin28a overexpression reduced C/EBPβ methylation via recruiting TET1 and enhanced C/EBPβ-mediated proliferation and migration of VSMCs. The opposite was noted in Lin28a knockdown cells.
CONCLUSION
Our findings suggest that the C/EBPβ-Lin28a axis is a driver of restenosis progression, and presents a promising therapeutic target for restenosis.

BACKGROUND:
The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China.
METHODS:
This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences.
RESULTS:
Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n = 278] vs . 43.7% [ n = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses.
CONCLUSION
This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

BACKGROUND:
Urolithiasis is a widespread disease with a high prevalence worldwide. This study aims to evaluate the disease burden of urolithiasis and its trends from 1990 to 2021 globally, based on the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 database.
METHODS:
The numbers and age-standardized rates (ASRs) of incidence, disability-adjusted life years (DALYs), and mortality of urolithiasis were extracted from GBD 2021 to represent the disease burden. Joinpoint regression analyses were conducted to assess the temporal trends in the burden of urolithiasis. The male-to-female ASR ratio indices were used to evaluate sex disparities. Additionally, we explored the relationship between the ASR ratio and the sociodemographic index (SDI).
RESULTS:
The total numbers of incidence, DALY, and mortality of urolithiasis were 105,983,780 cases (95% uncertainty interval [UI] = 88,349,356-128,645,155 cases), 693,444 cases (95% UI = 567,765-850,490 cases), and 17,672 cases (95% UI = 13,932-21,241 cases), respectively, in 2021. There is an increasing trend in the number of these measures globally, whereas the ASRs have decreased over the past 30 years. The age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) were significantly higher in males than in females in 2021. The sex disparities in the age-standardized DALY rate (ASDR) and ASMR of urolithiasis were negatively correlated with the SDI. In 2021, the ASIR of urolithiasis was 964.70 (95% UI = 801.26-1175.09) per 100,000 people in China, which is much lower than the global average (1242.84 [95% UI = 1034.94-1506.99] per 100,000 people). Compared with the global average, a more pronounced decline in ASIR was observed in China from 1793.16 (1446.0-2235.14) in 1990 to 964.70 (801.26-1175.09) per 100,000 people in 2021.
CONCLUSIONS
Urolithiasis poses a significant healthcare burden worldwide. More robust global and national strategies are warranted to address the prevention and treatment, especially in low SDI countries and regions.

BACKGROUND:
Bile acids (BAs) facilitate the progression of gastric intestinal metaplasia (GIM). Long non-coding RNAs (lncRNAs) dysregulation was observed along with the initiation of gastric cancer. However, how lncRNAs function in GIM remains unclear. This study aimed to explore the role and mechanism of lncRNA PVT1 in GIM, and provide a potential therapeutic target for GIM treatment.
METHODS:
We employed RNA sequencing (RNA-seq) to screen dysregulated lncRNAs in gastric epithelial cells after BA treatment. Bioinformatics analysis was conducted to reveal the regulatory mechanism. PVT1 expression was detected in 21 paired biopsies obtained under endoscopy. Overexpressed and knockdown cell models were established to explore gene functions in GIM. Molecular interactions were validated by dual-luciferase reporter assay, RNA immunoprecipitation (RIP), and chromatin immunoprecipitation (Ch-IP). The levels of relative molecular expression were detected in GIM tissues.
RESULTS:
We confirmed that lncRNA PVT1 was upregulated in BA-induced GIM model. PVT1 promoted the expression of intestinal markers such as CDX2 , KLF4 , and HNF4α . Bioinformatics analysis revealed that miR-34b-5p was a putative target of PVT1 . miR-34b-5p mimics increased CDX2 , KLF4 , and HNF4α levels. Restoration of miR-34b-5p decreased the pro-metaplastic effect of PVT1 . The interactions between PVT1 , miR-34b-5p, and the downstream target HNF4α were validated. Moreover, HNF4α could transcriptionally activated PVT1 , sustaining the GIM phenotype. Finally, the activation of the PVT1 /miR-34b-5p/ HNF4α loop was detected in GIM tissues.
CONCLUSIONS
BAs facilitate GIM partially via a PVT1/miR-34b-5p/HNF4α positive feedback loop. PVT1 may become a novel target for blocking the continuous development of GIM and preventing the initiation of gastric cancer in patients with bile reflux.

Processing for deodorization is widely used in the production of animal-derived Chinese medicinal materials. In this study, Heracles Neo ultra-fast gas-phase electronic nose combined with chemometrics was employed to analyze the overall odor difference of Cervi Cornu Pantotrichum(focusing on that derived from Cervus nippon Temminck in this study) before and after processing. The results showed that the electronic nose effectively distinguished between the medicinal materials and decoction pieces of Cervi Cornu Pantotrichum. HS-GC-MS was used to identify and quantify the volatile components in the medicinal materials and decoction pieces of Cervi Cornu Pantotrichum, and 35 and 37 volatile components were detected in the medicinal materials and decoction pieces, respectively. The medicinal materials and decoction pieces contained 28 common volatile components contributing to the odor of Cervi Cornu Pantotrichum. The odor activity value(OAV) of each volatile component was calculated based on the olfactory threshold and relative content. The results showed that there were 17 key odor substances such as isovaleraldehyde, 2-methylbutanal, isobutyraldehyde, hexanal, and methanethiol in the medicinal materials and decoction pieces of Cervi Cornu Pantotrichum. All of them had bad odor and were the main source of the odor of Cervi Cornu Pantotrichum. The results of principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) showed that there were significant differences in volatile components between the medicinal materials and decoction pieces of Cervi Cornu Pantotrichum. Based on the thresholds of P<0.05 and Variable Importance in Projection(VIP)>1, 21 differential volatile odor components were screened out. Among them, isopentanol, isovaleraldehyde, 2-methylbutanal, n-nonanal, and dimethylamine were the key differential odor compounds between the medicinal materials and decoction pieces of Cervi Cornu Pantotrichum. The odor compounds and their relative content reduced, and some flavor substances such as esters were produced after processing with wine, which was the main reason for the reduction of the odor after processing of Cervi Cornu Pantotrichum.
