OBJECTIVE To systematically evaluate the quality of the Heat-clearing and symptom-relieving formula and screen potential marker components that influence the quality of the formula. METHODS The contents of 11 components （calycosin-7- O - β -D-glucoside， ononin， hyperoside， isoquercitrin， baicalin， baicalein， cryptotanshinone， tanshinone Ⅱ A ， tanshinone Ⅰ， senkyunolide A， ferulic acid） in the Heat-clearing and symptom-relieving formula were determined by high-performance liquid chromatography-tandem mass spectrometry （HPLC-MS/MS）. Using the contents of the aforementioned components as variables， cluster analysis （CA）， principal component analysis （PCA）， and orthogonal partial least squares-discriminant analysis （OPLS-DA） were conducted using OriginPro 2024 software and SIMCA 14.1 software； marker components affecting the quality of the Heat-clearing and symptom-relieving formula were then screened based on the criteria of variable importance in the projection （VIP） value＞1 and P ＜0.05. The comprehensive evaluation of 20 batches of samples was carried out using the entropy weight-technique for order preference by similarity to ideal solution（TOPSIS） and grey correlation analysis （GCA） methods. RESULTS The contents of the above 11 components were 7.993-72.866， 4.542-31.228， 727.666-1 901.884， 496.846-1 293.279， 1 995.501-6 779.150， 54.500-241.280， 150.302-304.339， 79.698-189.206， 257.118-682.418， 5.498-21.687， 7.524-26.935 μg/g. CA， PCA and OPLS-DA results showed that 20 batches of samples were grouped into 2 categories. Q1， Q3， Q4， Q7-Q9， Q12， Q15， Q16 were grouped into one category， and the rest were grouped into another category； VIP values of ferulic acid， tanshinone Ⅱ A ， baicalin， cryptotanshinone， calycosin-7- O - β -D-glucoside and ononin were all greater than 1 （ P ＜0.05）. Both the entropy weight-TOPSIS and GCA methods showed that the samples ranked in the top 11 according to the euclidean distance and relative correlation degree were Q2， Q5， Q6， Q10， Q11， Q13， Q14， Q17-Q20. CONCLUSIONS The established HPLC-MS/MS method is rapid， accurate and highly sens itive. Combined with chemical pattern recognition analysis， entropy weight-TOPSIS and GCA methods， this method can be used to evaluate the quality of the Heat-clearing and symptom-relieving formula. Ferulic acid， tanshinone Ⅱ A ， baicalin， cryptotanshinone， calycosin-7- O - β -D-glucoside and ononin may be the marker components that affect the quality of this formula. The overall quality of 11 batches of the Heat-clearing and symptom-relieving formula， including Q17， is relatively superior.

Background/Aims: Non-pharmacological treatments are crucial for managing irritable bowel syndrome (IBS), yet patient engagement remains a challenge. Understanding patients' knowledge, attitudes, and practices regarding these treatments is essential for improving care. Methods: A cross-sectional study was conducted across 5 hospitals, from October 2023 to February 2024. A self-designed knowledge, attitudes, and practices questionnaire along with the IBS quality of life and IBS severity scoring system was administered, and 496 valid responses were analyzed. Statistical analyses included correlation tests, multivariate linear regression, and mediation effect analysis. Results: The median scores for knowledge, attitude, and practice were 28, 25.5, and 21, respectively. Significant positive correlations were found between knowledge-attitude (r = 0.195), knowledge-practice (r = 0.364), and attitude-practice (r = 0.151). The multivariate linear regression analysis further indicated that knowledge (β = 0.399, P < 0.001) and attitude (β = 0.219, P = 0.022) positively correlated with the practical performance. SEM revealed that knowledge had a significant direct effect on both attitude (β = 0.186, P = 0.013) and practice (β = 0.356, P = 0.006). However, the direct effect of attitude on practice was not significant, and attitude did not mediate the relationship between knowledge and practice. Conclusions IBS patients exhibit a significant gap between their positive attitudes and their actual practices concerning non-pharmacological treatments. Knowledge is a direct driver of practice, but positive attitudes alone are insufficient to translate into behavior. Healthcare providers must move beyond simply fostering positive attitudes and focus on targeted educational interventions that provide actionable knowledge and skills to improve patient outcomes.

Objective To investigate the levels and clinical significance of microRNA(miR)-17-5p and miR-141-3p in the serum of children with bacterial meningitis(BM).Methods A total of 111 children with BM ad-mitted to the First Affiliated Hospital of Xinjiang Medical University from May 2019 to May 2022 were in-cluded as the study group,and another 111 healthy children who underwent physical examinations were in-cluded as the control group.Real-time fluorescence quantitative PCR(qRT-PCR)was used to measure the ex-pression levels of serum miR-17-5p and miR-141-3p.Pearson correlation was used to analyze the correlation between serum miR-17-5p,miR-141-3p levels and inflammatory factors in children with BM.Multivariate Lo-gistic regression was applied to analyze the influencing factors of BM occurrence.Receiver operating character-istic(ROC)curve was applied to analyze the diagnostic value of miR-17-5p and miR-141-3p levels for BM.Re-sults The serum levels of miR-17-5p and miR-141-3p in the study group were obviously lower than those in the control group(P＜0.05),while the serum levels of C-reactive protein(CRP),procalcitonin(PCT),inter-feron-γ(IFN-γ),tumor necrosis factor-α(TNF-α),interleukin(IL)-1β,and IL-6 in the study group were high-er than those in the control group(P＜0.05).According to Pearson correlation analysis,miR-17-5p and miR-141-3p were negatively correlated with CRP,PCT,IFN-γ,TNF-α,IL-1β,and IL-6(P＜0.05).According to multivariate Logistic analysis,CRP,PCT,IFN-γ,TNF-α,IL-1β,and IL-6 were risk factors affecting the occur-rence of BM(P＜0.05),while miR-17-5p and miR-141-3p were protective factors affecting the occurrence of BM(P＜0.05).According to the ROC curve,the area under the curve(AUC)of serum level of miR-17-5p for diagnosing BM was 0.756,and the AUC of serum level of miR-141-3p for diagnosing BM was 0.720.The AUC of the combination of the two for diagnosing BM was 0.819,which was larger than that of single detec-tion(Zcombination vs.miR-17-5p=2.278,Zcombination vs.miR-141-3p=2.425,P＜0.05).Conclusion The expression levels of miR-17-5p and miR-141-3p in the serum of children with BM are reduced.The two are related to the levels of inflammatory factors,and their combined detection has a high diagnostic value for BM.

Objective To investigate the correlation of peripheral blood follicle suppressor-like protein L(FSTL-1)and chitosanidase 1(CHIT-1)levels with cardiovascular diseases(CVD)in hemodialysis patients and their clinical value.Methods A total of 150 hemodialysis patients treated in Chongqing Liangjiang New Area People's Hospital from January 2021 to June 2023(case group)and 60 healthy people who underwent medical checkups(control group)were selected.The case group consisted of 62 patients who had CVD(CVD group)and 88 patients who did not have CVD(non-CVD group).Enzyme-linked immunosorbent assay was used to detect the levels of FSTL-1 and CHIT-1 in peripheral blood.The levels of FSTL-1 and CHIT-1 among the groups were compared,and the correlation between the levels of FSTL-1 and CHIT-1 with the Gensini scores,high-sensitivity C-reactive protein(hs-CRP),troponin T(cTnT),and left ventricular ejection fraction(LVEF)were analyzed by Pearson's correlation test.Multivariate Logistic regression was used to analyze the influencing factors affecting the occurrence of CVD.Receiver operating characteristic(ROC)curve was used to assess the predictive efficacy of FSTL-1 and CHIT-1 for the occurrence of CVD.Results The levels of FSTL-1 and CHIT-1 were higher in the CVD group and non-CVD group than those in the control group(F=229.200,273.200,P＜0.05),and the levels of FSTL-1 and CHIT-1 in the CVD group were higher than those in the non-CVD group(P＜0.05).The peripheral blood FSTL-1 and CHIT-1 levels in hemodialysis patients were positively correlated with Gensini score,cTnT,hs-CRP(r=0.662,0.724,0.712,r=0.679,0.502,0.341,P＜0.05)and negatively correlated with LVEF(r=-0.463,-0.581,P＜0.05).Compared with the non-CVD group,CVD group had longer chronic kidney disease duration,higher hs-CRP,cTnT,Gensini score,FSTL-1,CHIT-1(P＜0.05),and lower LVEF(P＜0.05).High levels of cTnT,FSTL-1,and CHIT-1 were independent risk factors for CVD in hemodialysis patients(P＜0.05).The area under the curve of the com-bined detection of peripheral blood FSTL-1 and CHIT-1 levels for predicting the occurrence of CVD in hemo-dialysis patients was 0.852(95％CI:0.789-0.915),which was significantly larger than those of the single index of FSTL-1 and CHIT-1(Z=-2.084,-3.112,P=0.038,0.002).Conclusion The increased levels of peripheral blood FSTL-1 and CHIT-1 levels in CVD patients are correlated with cardiovascular injury,cardiac function,and inflammatory indexes in hemodialysis patients,which are independent risk factors affecting the occurrence of CVD in hemodialysis patients,and the combined detection of the two could improve the predic-tive efficacy for the occurrence of CVD in hemodialysis patients.

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by persistent inflammation and joint damage, accompanied by the accumulation of plasma cells, which contributes to its pathogenesis. Understanding the genetic alterations occurring during plasma cell differentiation in RA can deepen our comprehension of its pathogenesis and guide the development of targeted therapeutic interventions. Here, our study elucidates the intricate molecular mechanisms underlying plasma cell differentiation by demonstrating that PRDX1 interacts with DOK3 and modulates its degradation by the autophagy-lysosome pathway. This interaction results in the inhibition of plasma cell differentiation, thereby alleviating the progression of collagen-induced arthritis. Additionally, our investigation identifies Salvianolic acid B (SAB) as a potent small molecular glue-like compound that enhances the interaction between PRDX1 and DOK3, consequently impeding the progression of collagen-induced arthritis by inhibiting plasma cell differentiation. Collectively, these findings underscore the therapeutic potential of developing chemical stabilizers for the PRDX1-DOK3 complex in suppressing plasma cell differentiation for RA treatment and establish a theoretical basis for targeting PRDX1-protein interactions as specific therapeutic targets in various diseases.

OBJECTIVE To evaluate the efficacy and safety of intranasal corticosteroids （INCS） combined with oral H1- antihistamine （AH） in the treatment of allergic rhinitis. METHODS A comprehensive literature search was conducted in PubMed， Embase， CNKI， and VIP database to collect randomized controlled trial （RCT） that INCS combined with AH （experimental group） versus INCS （control group） in the treatment of allergic rhinitis from the inception to December 31， 2024. After study selection， data extraction， and quality assessment， a meta-analysis was performed by using RevMan 5.3 software. RESULTS A total of 12 RCTs were included in the meta-analysis， with a total of 1 842 patients. Results of meta-analysis showed that， compared with the control group， patients in the experimental group had a greater reduction in sneezing scores， rhinorrhea scores， nasal congestion scores， nasal itching scores， total nasal symptom scores， total ocular symptom scores， and rhinoconjunctivitis quality of life questionnaire scores （P＜0.05）. The incidence of headache was lower in the experimental group （P＜0.05）； whereas there were no significant differences between the two groups in the incidence of nosebleed， dryness of the mouth and nose， drowsiness， fatigue， and total adverse events （P＞0.05）. CONCLUSIONS Compared with INCS monotherapy， the combination of INCS and oral AH provides superior efficacy and safety in the treatment of allergic rhinitis.

Objective To analyze the microanatomical characteristics of the internal carotid artery(ICA)bifurcation through the lateral orbital keyhole(LOK)approach,thereby providing anatomical support for clipping the ICA bifurcation aneurysm.Methods A total of 15 cases(30 sides)of frozen cadaveric head specimens fixed with 10%formaldehyde and infused with red and blue latexes were selected.Craniotomy was performed by simulated LOK approach.The structure,and the course and quantity of the surrounding major perforator vessels of the ICA bifurcation were observed under the microscope,and the relevant data were recorded.Results The terminal diameter of ICA was(5.40±0.65)mm,and the length of ICA above the optic nerve plane was(11.99±1.86)mm.The proximal diameter of A1 was(1.85±0.26)mm,and the length of A1 was(12.90±3.13)mm;meanwhile,the proximal diameter of M1 was(3.64±0.64)mm,and the length of M1 was(15.54±2.10)mm.There were significant differences in the proximal diameter and length between A1 and M1(P<0.05).The angle between A1 and ICA was(77.61±19.43)°,while the angle between M1 and ICA was(137.93±10.31)°,and the difference between the two was statistically significant(P<0.001).There was no obvious linear relationship between the diameter ratio of A1 and ICA and the angle between A1 and ICA,and there was no obvious linear relationship between the diameter ratio of M1 and ICA and the angle between M1 and ICA.The peripheral perforator branches mainly consisted of 8.50(5.00,12.00)branches deriving from the proximal end of A1,0.50(0,3.25)branch deriving from the proximal end of M1,0(0,0.25)branch deriving from the distal end of ICA,(8.80±2.40)branches deriving from the posterior communicating artery,and(9.60±3.80)branches deriving from the anterior choroidal artery.The recurrent artery of Heubner was found in 28 sides,its main body could be the single trunk(30.00%),double trunk(43.00%),and triple trunk(20.00%).Conclusion The main structure and perforator branches of the ICA bifurcation can be clearly exposed through the LOK approach.When applying the LOK approach,it should be combined with the bifurcation angle,perforator branches distribution,and vascular variation characteristics of ICA bifurcation to optimize the aneurysm clipping plan,thereby thoroughly treating the lesion and minimizing the injury risk of perforator branches.

Objective:To investigate the clinical efficacy of cervical cerclage in singleton pregnancy with different degrees of short cervix.Methods:The clinical data of singleton pregnant women who underwent transvaginal ultrasound examination at 18-24 +6 weeks of gestation and found cervical dilation with cervical length (CL) ≤20 mm, and without history of spontaneous preterm delivery or late abortion in Women′s Hospital, Zhejiang University School of Medicine from January 2021 to September 2023 were collected and retrospectively analyzed. According to the case control matching, 78 pregnant women in the cerclage group and 78 women in the conservative treatment group were finally included. The pregnancy outcomes and neonatal prognosis of the two groups were compared. Meanwhile, the two groups of pregnant women were divided into three subgroups for stratification (CL≤10, 11-15, 16-20 mm). Multivariate logistic regression analysis and Kaplan-Meier curve were used to evaluate the effect of cervical cerclage on pregnancy outcomes in different subgroups. Results:(1) Compared with the conservative treatment group, the gestational age at delivery (median: 36 vs 37 weeks) and the duration of pregnancy extension (median: 90 vs 97 days) in the cerclage group were not significantly prolonged (all P>0.05). There was no significant difference in the cumulative non-delivery rate between the cerclage group and the conservative treatment group ( P=0.143). The rate of neonatal intensive care unit (NICU) admission in the cerclage group was significantly higher than that in the conservative treatment group (46.1% vs 31.2%, P<0.001), but there were no significant differences in other neonatal outcomes between the two groups (all P>0.05). (2) CL 16-20 mm subgroup: compared with the conservative treatment group (28 cases), the cerclage group (18 cases) had a significantly higher rate of preterm birth before 37 weeks of gestation (3.6% vs 6/18, P<0.001) and a significantly lower neonatal birth weight (median: 3 370 vs 2 925 g, P<0.001). There was no significant difference in the cumulative non-delivery rate between the cerclage group and the conservative treatment group ( P=0.168). (3) CL 11-15 mm subgroup: compared with the conservative treatment group (26 cases), the gestational age of delivery in the cerclage group (32 cases) was later (median: 36 and 37 weeks, respectively), and the difference was statistically significant ( P<0.05). The cumulative non-delivery rate in the cerclage group was significantly higher than that in the conservative treatment group ( P=0.001). (4) CL≤10 mm subgroup: compared with the conservative treatment group (24 cases), the pregnant women in the cerclage group (28 cases) had a later gestational age at delivery (median: 34 vs 37 weeks), a longer duration of pregnancy (median: 74 vs 97 days), and a larger newborn birth weight (median: 2 300 vs 3 165 g). The rates of preterm birth before 34 weeks of gestation (45.8% vs 14.3%) and before 37 weeks of gestation (83.3% vs 39.3%) were lower, and the differences were all statistically significant (all P<0.05). The cumulative non-delivery rate of pregnant women in the cerclage group was significantly higher than that in the conservative treatment group ( P<0.001). Conclusion:Cervical cerclage could significantly prolong the gestational weeks and improve the perinatal outcomes for singleton pregnant women with cervical internal orifice dilation and CL≤15 mm without a history of spontaneous preterm delivery or late abortion.

Purpose To explore the effect of Calumenin(CALU)on migration and invasion ability of gastric cancer cells,as well as epithelial-mesenchymal transition(EMT).Methods The immunohistochemical experiments and Western blot were applied to evaluate the protein level of CALU in gastric cancer.After constructing a gastric canc-er cell line with low expression of CALU,CCK8 assay,wound-healing analysis and Transwell migration and invasion assays were performed to determine cell proliferation,Migration and invasion ability.Western blot was performed to an-alyse the effect of CALU knockdown on EMT molecules.Results CALU expression was significantly higher in gastric cancer tissues compared to normal gastric tissues(P＜0.05),and high CALU expression was significantly associated with TNM stage and lymph node metastasis(P＜0.05).Compared with GES-1 cells,the protein expression of CALU upregulated in gastric cancer cells(P＜0.05).CALU knockdown suppressed the proliferation,migration,invasion of BGC823 cells and SGC7901 cells(P＜0.05).Rescue experimental evidence showed that synonymous mutations of CALU could reverse the inhibitory effect of CALU knockdown on the proliferation,migration,and invasion ability of gastric cancer cells(P＜0.05).Knockdown of CALU resulted in the downregulation of vimentin and Snail expression,while E-cadherin and β-catenin expression were upregulated in human gastric cancer cells(P＜0.05).Conclusion CALU knockdown inhibits the proliferation,migration,invasion,and EMT of human gastric cancer cells.
