Background and aims The mechanism of cholestatic liver injury (CLI) is unclear, and effective therapies are lacking. While peroxisome proliferator-activated receptor alpha (PPARα) agonists show potential hepatoprotective effect and pyroptosis is implicated in hepatocellular damage, how PPARα activation mitigates lithocholic acid (LCA)-induced pyroptosis remains unknown. Methods The hepatoprotective effect of PPARα agonists was evaluated in a mouse model of intrahepatic cholestasis induced by LCA. Liver injury was assessed via serum biochemistry, hematoxylin and eosin and TUNEL staining, and electron microscopy. Pyroptosis pathways were analyzed using real-time quantitative polymerase chain reaction, Western blot, and co-immunoprecipitation. Results Combined morphological, histopathological, and biochemical analyses confirmed that PPARα activation protects against CLI. Compared with LCA treatment alone, PPARα activation significantly attenuated the elevation of serum lactate dehydrogenase (LDH), the increased TUNEL-positive cells, and the formation of hepatocyte membrane pores. Mechanistically, PPARα activation suppressed both NOD-like receptor protein 3 (NLRP3) inflammasome-mediated pyroptosis and apoptosis protease-activating factor-1 (APAF-1)/CASPASE-3/GSDME-mediated pyroptosis. Furthermore, PPARα agonist pretreatment inhibited activation of the nuclear factor-kappa B (NF-κB) and forkhead box O1 (FOXO1) signaling pathways. Conclusions PPARα protects against LCA-induced CLI by inhibiting both NLRP3 inflammasome-mediated pyroptosis associated with NF-κB and APAF-1/CASPASE-3/GSDME-mediated pyroptosis associated with the FOXO1 signaling pathway.

Objective:To investigate the prognostic value of aldosterone synthase (CYP11B2) immunohistochemical expression in adrenal specimens for surgical outcomes of primary aldosteronism (PA).Methods:The clinical data of 99 patients who underwent total unilateral adrenalectomy from June 2022 to January 2023 at Beijing Anzhen Hospital was retrospectively analysed. The clinical data of 99 patients who underwent unilateral total adrenalectomy at Beijing Anzhen Hospital from June 2022 to January 2023 were retrospectively analyzed.There were 59 patients in the PA group, age (53.02±10.56) years, body mass index (BMI) (26.28±4.33) kg/m 2, preoperative aldosterone 29.0(15.9, 61.5)ng/dl, plasma renin 1.3(0.6, 2.8)μIU/ml, aldosterone renin ratio (ARR) 19.3(9.1, 59.2) μg/μIU, preoperative potassium (3.60±0.69) mmol/L, and systolic blood pressure (156.54±21.39) mmHg (1 mmHg=0.133 kPa).There were 40 cases in the nonfunctioning adenoma (NFA) group, age (57.23±9.39) years, BMI (27.07±3.46) kg/m 2, preoperative aldosterone 9.0(7.2, 14.1) ng/dl, plasma renin 18.0(5.2, 47.6)μIU/ml, ARR 0.6(0.2, 1.4) μg/μIU, preoperative potassium (4.17±0.41) mmol/L, and systolic blood pressure (157.97±26.87) mmHg. The differences between the two groups were statistically significant for potassium ( P<0.01), aldosterone ( P=0.012), renin ( P<0.01), and ARR ( P<0.01).Surgical outcomes were assessed using the Consensus on the Outcome of Surgery for Primary Aldosteronism (PASO) (complete/partial/no success for clinical and biochemical outcomes). CYP11B2 expression was evaluated by immunohistochemistry using the 2022 World Health Organization's histopathology of primary aldosteronism (HISTALDO) criteria. The correlation between the expression of CYP11B2 and surgical outcomes was assessed. Results:The mean follow-up of 99 patients was (11.73±4.92) months. Of these, 36 out of 59 PA patients had positive CYP11B2 expression in their adrenal specimens, while 23 were negative; all 40 NFA patients were negative for CYP11B2. Among the 36 CYP11B2-positive PA patients, there were 19 cases of aldosterone-producing adenomas, 3 aldosterone-producing nodules, 4 aldosterone-producing micronodules, 8 multiple aldosterone-producing micronodules, and 2 aldosterone-producing diffuse hyperplasia. 36 cases of CYP11B2-positive PA patients had complete clinical success in 15 cases, partial success in 20 cases, and no success in 1 case, and complete biochemical success in 24 cases, partial success in 11 cases, and no success in 1 case; 23 CYP11B2-negative PA patients had complete clinical success in 4 cases, partial success in 15 cases, and no success in 4 cases, and complete biochemical success in 6 cases, partial success in 15 cases, and no success in 2 cases. Adrenal specimens from CYP11B2-positive PA patients had significantly better clinical ( P=0.038) and biochemical ( P=0.008) success rates than CYP11B2-negative PA patients. Patients with aldosterone-producing adenomas had complete clinical success in 8 cases, partial success in 11 cases, and no success in 0 cases, and biochemical success was completely achieved in 16 cases, partially achieved in 2 cases, and not successful in 1 case. They also had significantly higher clinical ( P=0.028) and biochemical ( P<0.01) success rates compared to CYP11B2-negative PA patients. Conclusions:Patients with PA who had immunohistochemical staining for CYP11B2 positivity and high expression in adrenal specimens had a better postoperative clinical and biochemical prognosis. Patients with aldosterone-producing adenomas had the greatest postoperative outcome of all pathological subtypes of PA.

As new evidence emerges, treatment strategies toward the functional cure of chronic hepatitis B are evolving. In 2019, a panel of national hepatologists published a Consensus Statement on the functional cure of chronic hepatitis B. Currently, an international group of hepatologists has been assembled to evaluate research since the publication of the original consensus, and to collaboratively develop the updated statements. The 2.0 Consensus was aimed to update the original consensus with the latest available studies, and provide a comprehensive overview of the current relevant scientific literatures regarding functional cure of hepatitis B, with a particular focus on issues that are not yet fully clarified. These cover the definition of functional cure of hepatitis B, its mechanisms and barriers, the effective strategies and treatment roadmap to achieve this endpoint, in particular new surrogate biomarkers used to measure efficacy or to predict response, and the appropriate approach to pursuing a functional cure in special populations, the development of emerging antivirals and immunomodulators with potential for curing hepatitis B. The statements are primarily intended to offer international guidance for clinicians in their practice to enhance the functional cure rate of chronic hepatitis B.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

[Purpose]To analyze the incidence and mortality rates of female breast cancer in Henan Province in 2020 and the trends from 2010 to 2020.[Methods]Breast cancer incidence and mor-tality data stratified by urban and rural areas and age groups were collected from Henan Provincial tumor registry,and the province's household population statistics were used.The crude incidence/mortality rate,age-standardized incidence/mortality rate by Chinese standard population(ASIRC/ASMRC)and world standard population(ASIRW/ASMRW),cumulative rate(0～74 year old)were calculated.The annual percentage change(APC),average annual percentage change(AAPC)and 95％confidence interval(CI)were calculated using Joinpoint software to analyze the trends of the incidence and mortality from 2010 to 2020.[Results]In 2020,24 744 new cases and 4 989 deaths of female breast cancer were documented in Henan Province,with a crude incidence rate of 46.96/105,ASIRC of 38.43/105 and ASIRW of 35.71/105;a crude mortality rate of 9.47/105,ASMRC of 6.80/105 and ASMRW of 6.72/105,respectively.The above indicators in urban areas were signifi-cantly higher than those in rural areas.The highest incidence was observed in the age group of 50～54 years old,while the highest mortality reached in the age group of 85 years old and above.From 2010 to 2020,the overall incidence of female breast cancer showed a slow upward trend(AAPC=2.09％,95％CI:0.62％～3.58％,P=0.010),while the mortality rate exhibited a signif-icant downward trend(AAPC=-3.49％,95％CI:-5.62％～-1.30％,P=0.005).[Conclusion]The incidence and mortality rates of female breast cancer in Henan Province are still at a high level,and corresponding preventive measures and control strategies are needed to effectively reduce the health hazards of breast cancer to women.

The choice of biopsy method is critical in diagnosing prostate cancer (PCa). This retrospective cohort study compared systematic biopsy (SB) or cognitive fusion-targeted biopsy combined with SB (CB) in detecting PCa and clinically significant prostate cancer (csPCa). Data from 2572 men who underwent either SB or CB in Fudan University Shanghai Cancer Center (Shanghai, China) between January 2019 and December 2023 were analyzed. Propensity score matching (PSM) was used to balance baseline characteristics, and detection rates were compared before and after PSM. Subgroup analyses based on prostate-specific antigen (PSA) levels and Prostate Imaging-Reporting and Data System (PI-RADS) scores were performed. Primary and secondary outcomes were the detection rates of PCa and csPCa, respectively. Of 2572 men, 1778 were included in the PSM analysis. Before PSM, CB had higher detection rates for both PCa (62.9% vs 52.4%, odds ratio [OR]: 1.54, P < 0.001) and csPCa (54.9% vs 43.3%, OR: 1.60, P < 0.001) compared to SB. After PSM, CB remained superior in detecting PCa (63.1% vs 47.9%, OR: 1.86, P < 0.001) and csPCa (55.0% vs 38.2%, OR: 1.98, P < 0.001). In patients with PSA 4-12 ng ml -1 (>4 ng ml -1 and ≤12 ng ml -1 , which is also applicable to the following text), CB detected more PCa (59.8% vs 40.7%, OR: 2.17, P < 0.001) and csPCa (48.1% vs 27.7%, OR: 2.42, P < 0.001). CB also showed superior csPCa detection in those with PI-RADS 3 lesions (32.1% vs 18.0%, OR: 2.15, P = 0.038). Overall, CB significantly improves PCa and csPCa detection, especially in patients with PSA 4-12 ng ml -1 or PI-RADS 3 lesions.

Andrographolide sulfonate (AS) is a sulfonated derivative of andrographolide extracted from Andrographis paniculata (Burm.f.) Nees, and has been approved for several decades in China. The present study aimed to investigate the novel therapeutic application and possible mechanisms of AS in the treatment of rheumatoid arthritis. Results indicated that administration of AS by injection or gavage significantly reduced the paw swelling, improved body weights, and attenuated pathological changes in joints of rats with adjuvant-induced arthritis. Additionally, the levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and IL-1β in the serum and ankle joints were reduced. Bioinformatics analysis, along with the spleen index and measurements of IL-17 and IL-10 levels, suggested a potential relationship between AS and Th17 cells under arthritic conditions. In vitro, AS was shown to block Th17 cell differentiation, as evidenced by the reduced percentages of CD4⁺ IL-17A⁺ T cells and decreased expression levels of RORγt, IL-17A, IL-17F, IL-21, and IL-22, without affecting the cell viability and apoptosis. This effect was attributed to the limited glycolysis, as indicated by metabolomics analysis, reduced glucose uptake, and pH measurements. Further investigation revealed that AS might bind to hexokinase2 (HK2) to down-regulate the protein levels of HK2 but not glyceraldehyde-3-phosphate dehydrogenase (GAPDH) or pyruvate kinase M2 (PKM2), and overexpression of HK2 reversed the inhibition of AS on Th17 cell differentiation. Furthermore, AS impaired the activation of phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signals in vivo and in vitro, which was abolished by the addition of lactate. In conclusion, AS significantly improved adjuvant-induced arthritis (AIA) in rats by inhibiting glycolysis-mediated activation of PI3K/AKT to restrain Th17 cell differentiation.

Objective To identify potential ergonomic risk factors of works and quickly assess their risks of developing work-related musculoskeletal disorders (WMSDs) in the medical staff. Methods A total of 188 medical staff were selected as the research objects using a two-stage random sampling method. The method for the identification of musculoskeletal stress factors (PLIBEL) was used to analyze the adverse ergonomic factors in the work process, and the rapid entire body assessment (REBA) was used to quickly assess the whole-body posture load. Results The PLIBEL assessment results showed that various adverse ergonomic factors affected different parts of the body during the work process of medical staff. Specifically, 18 adverse ergonomic factors were identified in the neck, shoulders, and upper back, while 10 adverse ergonomic factors were identified in the elbow, forearm, hand, and lower back. Rehabilitation therapists and nurses engaged in patient handling in general wards and medication preparation and blood collection were exposed to ≥35 adverse ergonomic factors. The REBA assessment showed that the REBA score was 3-12 points for medical staff during their work process. Rehabilitation therapists were classified as having an extremely high ergonomic risk. High-risk occupations included ward housekeeping nurses, surgery assistant nurses, operating-room instrument nurses, and surgeons. Medium-risk occupations included general ward nurses (medication preparation and blood collection, venipuncture/infusion, and patient handling), intensive care unit (ICU) nurses, internal medicine residents, and dentists. Low-risk occupations included administrative front-desk nurses, outpatient internal medicine physicians, and technicians/physicians in ultrasonography, laboratory medicine, physical examination, and occupational health departments. Conclusion Adverse ergonomic factors of medical staff predominantly affect the neck, shoulders, upper back, elbows, forearms, hands, and the lower back during the work process. Rehabilitation therapists, ward housekeeping nurses, ICU nurses, operating-room instrument nurses, and surgeons are high-risk groups for WMSDs. Attention should be paid to the management and control of adverse ergonomic factors for medical staff to prevent the occurrence of WMSDs.

Breast cancer(BRCA)remains one of the leading causes of cancer-related deaths worldwide due to its high rates of metastasis and recurrence,making it crucial to explore its underlying molecular mechanisms.Our previous study demonstrated that miR-326 inhibits BRCA progression by targeting EPH receptor B3(EPHB3).This study further explores the molecular mechanism by which long non-coding RNAs(LncRNAs)regulates BRCA progression via the competing endogenous RNA(ceRNA)mecha-nism,in which it competes with EPHB3 for miR-326 binding.Bioinformatics analysis identified LncRNA Small Nucleolar RNA Host Gene 12(SNHG12)as a potential miR-326-binding molecule.SNHG12 was found to be significantly upregulated in BRCA tissues,exhibiting a negative correlation trend with miR-326 and a positive correlation trend with EPHB3,suggesting its potential involvement in the ceRNA regu-latory network.Nuclear-cytoplasmic fractionation assays revealed cytoplasmic localization of SNHG12,while dual-luciferase reporter assays confirmed its direct binding to miR-326.Functional experiments demonstrated that SNHG12 knockdown significantly suppressed BRCA cell proliferation,invasion,and migration,while miR-326 inhibition reversed these effects.Furthermore,miRNA pulldown assay re-vealed significant enrichment of SNHG12 and EPHB3 in the miR-326 pulldown products,indicating di-rect binding between them.Western blotting and rescue experiments revealed that SNHG12 upregulates EPHB3 expression by sponging miR-326,thereby promoting the malignant behaviors of BRCA cells.Col-lectively,this study revealed that LncRNA SNHG12 promotes BRCA progression by regulating the miR-326/EPHB3 axis through a ceRNA mechanism.The SNHG12/miR-326/EPHB3 pathway may represent a promising target for the molecular diagnosis and targeted therapy of BRCA.
