ObjectiveTo evaluate the clinical efficacy and safety of the traditional Chinese medicine （TCM） compound Chaiqin Xiaoyong Decoction （柴芩消痈饮， CXD） combined with Jinhuang Ointment （金黄膏， JO） in treating the nodular stage of acne mastitis of liver meridian heat accumulation type. MethodsA randomized， double-blind， placebo-controlled clinical trial was conducted. A total of 108 patients with liver meridian heat accumulation type acne mastitis in the nodular stage were randomly assigned to a treatment group and a control group， with 54 patients in each group. Both groups received topical application of JO once daily at a thickness of 3~5 mm for 8 hours， along with standard nursing care. On this basis， the treatment group received oral CXD granules， while the control group received placebo granules， administered twice daily， 3 sachets per dose， for 14 consecutive days. Clinical efficacy， TCM symptom scores， nodule size， visual analogue scale （VAS） pain scores， white blood cell （WBC） count， C-reactive protein （CRP） level， and systemic immune-inflammation index （SII） were compared. At the end of treatment， efficacy and safety indicators were evaluated. A 6-month follow-up was conducted to compare the proportion of patients undergoing surgical treatment. ResultsThe total clinical efficacy rate in the treatment group was 90.38% （47/52）， significantly higher than 32.00% （16/50） in the control group （P＜0.01）. The treatment group also showed significantly lower TCM symptom scores， VAS scores， nodule size， WBC count， CRP level， and SII （P＜0.05 or P＜0.01）. During follow-up， the surgical intervention rate in the treatment group was 5.77% （3/52）， lower than 14.00% （7/50） in the control group， with a statistically significant difference （P＜0.01）. No significant abnormalities were observed in safety indicators before and after treatment in either group. ConclusionCXD effectively reduces nodule size and alleviates symptoms such as redness and pain in patients with acne mastitis of liver meridian heat accumulation type， improves TCM symptom scores， enhances overall clinical efficacy， and demonstrates good safety.

BACKGROUND: The American Heart Association recently released a new cardiovascular health (CVH) metric, Life's Essential 8 (LE8), for health promotion. However, the association between LE8 scores and the risk of chronic kidney disease (CKD) remains uncertain. We aimed to explore the association of LE8 scores with new-onset CKD and examine whether socioeconomic deprivation and genetic risk modify this association. METHODS: A total of 286,908 participants from UK Biobank and without prior CKD were included between 2006 and 2010. CVH was categorized using LE8 scores: low (LE8 scores <50), moderate (LE8 scores ≥50 but <80), and high (LE8 scores ≥80). The study outcome was new-onset CKD, ascertained by data linkage with primary care, hospital inpatient, and death data. Cox proportional hazard regression models were used to investigate the association between CVH categories and new-onset CKD. RESULTS: During a median follow-up of 12.5 years, 8857 (3.1%) participants developed new-onset CKD. Compared to the low CVH group, the moderate (adjusted hazards ratio [HR], 0.50; 95% confidence interval [CI]: 0.47-0.53) and high CVH (adjusted HR, 0.31; 95% CI: 0.27-0.34) groups had a significantly lower risk of developing new-onset CKD. The population-attributable risk associated with high vs. intermediate or low CVH scores was 40.3%. Participants who were least deprived ( vs.  most deprived; adjusted HR, 0.75; 95% CI: 0.71-0.79) and with low genetic risk of CKD ( vs.  high genetic risk; adjusted HR, 0.89; 95% CI: 0.85-0.94) had a significantly lower risk of developing new-onset CKD. However, socioeconomic deprivation and genetic risks of CKD did not significantly modify the relationship between LE8 scores and new-onset CKD (both P -interaction >0.05). CONCLUSION Achieving a higher LE8 score was associated with a lower risk of developing new-onset CKD, regardless of socioeconomic deprivation and genetic risks of CKD.

OBJECTIVES: In recent years, the incidence and detection rate of pancreatic cystic lesions (PCLs) have increased significantly. Endoscopic ultrasound (EUS) plays an indispensable role in the diagnosis and differential diagnosis of PCLs. However, evidence comparing the diagnostic performance of EUS-guided fine-needle aspiration (EUS-FNA) and fine-needle biopsy (FNB) remains limited. This study aims to compare the diagnostic yield, adequacy of tissue acquisition, and safety between EUS-FNA and EUS-FNB in evaluating PCLs to inform clinical practice. METHODS: A retrospective review was conducted on patients with PCLs who underwent either EUS-FNA or EUS-FNB between January 2014 and August 2021. The diagnostic yield, tissue acquisition adequacy, and incidence of adverse events were compared between the 2 groups. RESULTS: A total of 90 patients with PCLs were included (52 in the FNA group and 38 in the FNB group). The diagnostic yield was similar between the FNA and FNB groups (94.2% vs 94.7%, P>0.05). The adequacy of tissue acquisition was 71.2% in the FNA group and 81.6% in the FNB group (P>0.05). No statistically significant difference was observed in the incidence of adverse events between the 2 groups (P>0.05). CONCLUSIONS Both EUS-FNA and EUS-FNB demonstrate equally high diagnostic yields and tissue adequacy in PCLs, with excellent safety profiles. Both methods are safe and effective diagnostic tools for evaluating PCLs.

Abdominal aortic aneurysm (AAA) is a deadly condition of the aorta, carrying a significant risk of death upon rupture. Currently, there is a dearth of efficacious pharmaceutical interventions to impede the advancement of AAA and avert it from rupturing. Here, we investigated dihydromyricetin (DHM), one of the predominant bioactive flavonoids in Ampelopsis grossedentata (A. grossedentata), as a potential agent for inhibiting AAA. DHM effectively blocked the formation of AAA in angiotensin II-infused apolipoprotein E-deficient (ApoE^-/-) mice. A combination of network pharmacology and whole transcriptome sequencing analysis revealed that DHM's anti-AAA action is linked to heme oxygenase (HO)-1 (Hmox-1 for the rodent gene) and hypoxia-inducible factor (HIF)-1α in vascular smooth muscle cells (VSMCs). Remarkably, DHM caused a robust rise (∼10-fold) of HO-1 protein expression in VSMCs, thereby suppressing VSMC inflammation and oxidative stress and preserving the VSMC contractile phenotype. Intriguingly, the therapeutic effect of DHM on AAA was largely abrogated by VSMC-specific Hmox1 knockdown in mice. Mechanistically, on one hand, DHM increased the transcription of Hmox-1 by triggering the nuclear translocation and activation of HIF-1α, but not nuclear factor erythroid 2-related factor 2 (NRF2). On the other hand, molecular docking, combined with cellular thermal shift assay (CETSA), isothermal titration calorimetry (ITC), drug affinity responsive target stability (DARTS), co-immunoprecipitation (Co-IP), and site mutant experiments revealed that DHM bonded to HO-1 at Lys243 and prevented its degradation, thereby resulting in considerable HO-1 buildup. In summary, our findings suggest that naturally derived DHM has the capacity to markedly enhance HO-1 expression in VSMCs, which may hold promise as a therapeutic strategy for AAA.

OBJECTIVE To establish a core competency evaluation system for drug clinical trial quality management personnel in China and validate its application. METHODS Based on the scope of work， responsibilities， and role positioning of quality management personnel in drug clinical trials， a preliminary draft of the core competency evaluation system was constructed through literature analysis and expert consultation. The draft was refined through a Delphi method involving 17 experts who provided feedback and revisions， ultimately forming a complete evaluation system. The developed system was applied to conduct electronic surveys from March to May 2024 among 110 quality management personnel from 38 drug clinical trial institutions， comparing their scores on indicator importance and self-assessed capabilities. RESULTS The response rate of both rounds of questionnaire survey was 100%， with Kendall’s W coefficients of 0.256 and 0.277 （P＜0.001 for both）， and an expert authority coefficient of 0.946. The finalized evaluation system for core competencies of clinical trial quality management personnel comprised 9 primary indicators， covering individual professional competence， communication skills， implementation condition verification， informed consent process review， clinical trial execution monitoring， adverse event disposal， reporting and documentation， trial record examination， trial report auditing， and inspection of other tasks， and 107 secondary indicators. Empirical research revealed significant discrepancies between importance scores and self-assessed competency scores across 70 indicators among 110 respondents （P＜0.05）. Indicators with relatively notable gaps between importance scores and self-assessed competency scores included in-depth understanding of Good Clinical Practice （GCP） requirements （0.34-point gap）， familiarity with national and institutional clinical trial inspection priorities （0.24-point gap），etc. CONCLUSIONS The indicator system constructed in this study has good scientificity and reliability. Clinical trial quality management personnel demonstrate deficiencies in multiple critical competencies， highlighting the urgent need for targeted training programs to enhance their overall professional capabilities.

Objective To explore the effect of Orem self-care mode on disease management ability and quality of life of diabetic patients.Methods A total of 130 patients with diabetes were divided into the control group and the observation group by random number table method,65 cases in each group.The control group underwent routine nursing intervention,and the observation group were treated with Orem self-care mode.The intervention effects of the two groups were compared.Results After the intervention,the knowledge of diabetes management,the self-care ability and the improvement of quality of life in the observation group were better than those in the control group(P<0.05).Conclusion The application of Orem self-care mode can significantly improve patients'cognition of the disease and self-management ability,which is of great significance to improve patients'condition and improve their quality of life.

Lung cancer ranks the top of malignancies that cause cancer-related deaths worldwide.The leaves of Morus alba L are traditional Chinese medicine widely applied in respiratory diseases.Our previous work has demonstrated the anti-lung cancer effect of secondary metabolites of mulberry leaf,but their mechanism of action has still not fully elucidated.We synthesized Moracin N(MAN)-Probe conjugated with alkyne to label lung cancer cells and identified protein targets by chemical proteomic analysis.MAN and its probe exerted similar growth-inhibitory effect on human lung cancer cells.Chemical proteomic results showed that MAN targeted the programmed death ligand 1(PD-L1)checkpoint pathway and T cell receptor(TCR)signaling pathway,indicating its immune-regulatory function.Cell-free surface plasmon resonance(SPR)results showed the direct interaction of MAN with PD-L1 protein.Molecular docking analysis demonstrated that MAN bound to E158 residue of PD-L1 protein.MAN downregulated the expression levels of PD-L1 in a time-and dose-dependent manner and disrupted the PD-L1/programmed death 1(PD-1)binding,including other secondary metabolites of mulberry leaves Guangsangon E(GSE)and Chalcomoracin(CMR).Human peripheral blood mononuclear cells(PBMCs)co-cultured with MAN-treated A549 cells,resulting in the increase of CD8+GZMB+T cells and the decrease of CD8+PD-1+T cells.It suggested that MAN exerts anti-cancer effect through blocking the PD-L1/PD-1 signaling.In vivo,MAN combined with anti-PD-1 antibody significantly inhibited lung cancer development and metastasis,indicating their synergistic effect.Taken together,secondary metabolites of mulberry leaves target the PD-L1/PD-1 signaling,enhance T cell-mediated immunity and inhibit the tumorigenesis of lung cancer.Their modulatory effect on tumor microenvironment makes them able to enhance the therapeutic efficacy of immune checkpoint inhibitors in lung cancer.

OBJECTIVE To study the differences in toxicity between intravenous(iv)administration and aqueous solution exposure of Dichroa alkali salt(DAS)in zebrafish.METHODS ① Well-devel-oped zebrafish larvae of 2 d post fertilization(2 dpf)were randomly divided into the normal control(no treatment),solvent control(saline,iv),and DAS groups(0.125,0.25,0.50,1.00 and 2.00 mg·kg-1,iv)before being observed for 3 consecutive days after administration.A heart rate of 0 was determined as death of zebrafish,and the mortality rate,maximum non-lethal dose(MNLD),and 10 percent lethal dose(LD10)were calculated.The incidence of venous sinus congestion,pericardial edema,slowing heart rate and blood flow of zebrafish in the 0.50 and 2.00 mg·kg-1 groups were observed and calculated by somatoscopic microscopy at 4 h after drug administration.Zebrafish larvae were iv given DAS at doses of 0.041,0.136,0.412,and 0.452 mg·kg-1 while the malformation phenotypes of zebrafish larvae development were observed under a stereomicroscope for 3 consecutive days,including pericardial edema,abnormal heart rate,slow blood flow,loss of circulation,eye abnormalities,brain malforma-tions,jaw abnormalities,loss/degeneration of the liver,delayed yolk sac absorption,intestinal abnormal-ities,abnormal body coloration,body edema,curvature of the trunk/tail/nodal cord and muscle degener-ation before the incidence was calculated.②Zebrafish larvae were randomly divided into a normal control group and DAS aqueous solution exposure groups at concentrations of 2.5,5.0,10.0,25.0,50.0,75.0,and 100.0 mg·L-1,observed for 3 d until the mortality rate,LD10,and MNLD were calculated.Zebrafish were exposed to DAS aqueous solutions at concentrations of 0.32,1.06,3.20,and 11.00 mg·L-1,and the malformation phenotypes of zebrafish larvae development were observed under a stereomicro-scope for 3 consecutive days to calculate the incidence.RESULTS ① The MNLD and LD10 of DAS iv administered to zebrafish larvae were 0.412 and 0.452 mg·kg-1,respectively.Compared with the solvent control group,4 h after DAS iv administration,the incidence of sinus congestion,slow heart rate and pericardial edema in the 0.50 and 2.00 mg·kg-1 groups significantly increased(P<0.05,P<0.01),so was the incidence of slow blood flow in the 2.00 mg·kg-1 group(P<0.01).The rate of delayed yolk sac absorption was significantly increased in the 0.041,0.136,0.412,and 0.452 mg·kg-1 groups(P<0.05,P<0.01),so was the mortality rate in the 0.452 mg·kg-1 group(P<0.05),with pericardial edema observed in the dead zebrafish.② The MNLD and LD10 of DAS aqueous solution exposure for zebrafish larvae were 3.20 and 11.00 mg·L-1,respectively.Compared with the normal control group,the incidence of decreased heart rate and slow blood flow was significantly increased in the 3.20 and 11.00 mg·L-1 groups(P<0.01),so was the incidence of significantly darkened intestines in the 1.06,3.20,and 11.00 mg·L-1 groups(P<0.01).The incidence of delayed yolk sac absorption was significantly increased in the 0.32,1.06,3.20,and 11.00 mg·L-1 groups(P<0.05,P<0.01),so was the incidence of trunk curvature and lower jaw malformation in the 11.00 mg·L-1 group(P<0.01).CONCLUSION The toxic phenotypes of DAS are different between iv administration and aqueous solution exposure in zebrafish larvae.DAS aqueous solution exposure can not only lead to slow heart rate,slow blood rheology,delayed yolk sac absorption and intestinal blackening,but also induce neurodevelopmental toxicity.However,iv adminis-tration can effectively ward off significant gastrointestinal damage and neurodevelopmental toxicity.

Objective To explore the effectiveness of transperineal tension-free repair of rectal seromuscular layer in the treatment of acquired rectovestibular fistula.Methods Clinical data of 97 girls with acquired rectovestibular fistula from May 2016 to November 2023 were enrolled.The surgical age ranged from 6 months to 11 years old(median,3 years old).The fistula was disconnected and resected via the perineal approach.The anterior wall of the rectum was fully disconnected.Then the fistula was repaired with horizontal continuous tension-free suture of rectal plasmomuscular layer with 5-0 PDS sutures.After continuous suture reinforcement,the perineal muscle layer and skin were longitudinally continuously sutured.The internal fistula opening was exposured with an anal dilator or small hook,and the mucosal layer was continuously sutured with 5-0 PDS sutures.Postoperatively,the anal tube and urinary tube were retained for 5-7 d and antibiotics was administered for treatment.Results The mean operation time was(60.5±9.0)min,the mean fistula diameter was(5.2±2.1)mm,and the mean hospital stay was(7.4±1.9)d.The follow-ups time was 4.5 months to 8.5 years(median,4.25 years).Primary healing was achieved in 92 cases(94.8％),with satisfactory perineal appearance,smooth stool passage,and regular defecation.Fistula recurred within 5-10 d after operation in 5 cases(5.2％),2 of which healed after 3 weeks of sitz baths by using 3％boric acid or Kangfuxin solution,2 of which healed after second operation,and 1 of which experienced recurrence after secondary fistula repair.Conclusion Transperineal tension-free rectal seromuscular layer repair is a simple,safe,and effective surgical method for the treatment of acquired rectovestibular fistula in girls.

Objective:To evaluate the efficacy and safety of omalizumab in the treatment of chronic urticaria in children.Methods:A retrospective study was conducted. Patients with chronic urticaria were collected from the Department of Dermatology, Hunan Children′s Hospital from January to December 2021, and divided into a control group and a combination group according to different medication regimens. The patients in the combination group received subcutaneous injections of omalizumab (150 mg, once every 4 weeks) combined with conventional-dosage antihistamines, while the patients in the control group were only treated with double-dosage or multiple types of antihistamines. The course of treatment was 3 to 6 months. The clinical efficacy and adverse reactions were evaluated at 3, 6, and 12 months after the start of treatment, and the recurrence was evaluated at 3 and 6 months after the end of treatment.Results:A total of 46 children with chronic urticaria were collected. There were 23 children (13 males and 10 females) in the combination group, aged from 6 to 17 years and including 16 aged from 6 to 12 years and 7 aged from 13 to 17 years; according to the total serum IgE levels before treatment, the patients in the combination group were divided into an increased IgE subgroup (11 cases) and a normal IgE subgroup (12 cases). In the control group, there were 13 males and 10 females, aged from 6.33 to 16 years and including 15 aged from 6 to 12 years and 8 aged from 13 to 17 years. At 3, 6, and 12 months after the start of treatment, the response rates in the combination group were all 86.96% (20/23), which were all significantly higher than those in the control group (52.17% [12/23], 56.52% [13/23], 56.52% [13/23], P = 0.010, 0.022, 0.022, respectively). In the combination group, the response rates at 3, 6, and 12 months after the start of treatment were all 14/16 in the children aged 6 to 12 years and 6/7 in those aged 13 to 17 years, and there were no significant differences between the two age groups (all χ2 = 0.01, P = 0.907) ; in the control group, the response rates were 5/15, 6/15 and 5/15 respectively in the children aged 6 to 12 years, which were all significantly lower than those in the combination group ( P = 0.002, 0.006, 0.006, respectively). In the combination group, the response rates at 3, 6, and 12 months after the start of treatment were all 9/11 in the increased IgE subgroup and 11/12 in the normal IgE subgroup, and there were no significant differences between the two subgroups (all P = 0.484). During the treatment, no serious adverse reactions were observed in the combination group or control group, and mild somnolence only occurred in 2 children in the control group. At 3 months after the end of treatment, no recurrence was observed in 16 patients in the combination group, 2 out of 6 patients experienced recurrence in the control group, and the recurrence rate was lower in the combination group than in the control group ( P = 0.030) ; at 6 months after the end of treatment, no recurrence was observed in 16 patients in the combination group, 3 out of 6 patients experienced recurrence in the control group, and the recurrence rate was lower in the combination group than in the control group ( P = 0.022) . Conclusion:Omalizumab combined with conventional-dosage antihistamines could improve the clinical efficacy and reduce the recurrence rate in the treatment of chronic urticaria in children, with few adverse reactions.
