Sustained inflammatory responses are closely related to various severe diseases,and inhibiting the excessive activation of inflammasomes and pyroptosis has significant implications for clinical treatment.Natural products have garnered considerable concern for the treatment of inflammation.Huanglian-Wumei decoction(HLWMD)is a classic prescription used for treating inflammatory diseases,but the necessity of their combination and the exact underlying anti-inflammatory mechanism have not yet been elucidated.Inspired by the supramolecular self-assembly strategy and natural drug compatibility theory,we successfully obtained berberine(BBR)-chlorogenic acid(CGA)supramolecular(BCS),which is an herbal pair from HLWMD.Using a series of characterization methods,we confirmed the self-assembly mechanism of BCS.BBR and CGA were self-assembled and stacked into amphiphilic spherical supra-molecules in a 2:1 molar ratio,driven by electrostatic interactions,hydrophobic interactions,and π-πstacking;the hydrophilic fragments of CGA were outside,and the hydrophobic fragments of BBR were inside.This stacking pattern significantly improved the anti-inflammatory performance of BCS compared with that of single free molecules.Compared with free molecules,BCS significantly attenuated the release of multiple inflammatory mediators and lipopolysaccharide(LPS)-induced pyroptosis.Its anti-inflammatory mechanism is closely related to the inhibition of intracellular nuclear factor-kappaB(NF-κB)p65 phosphorylation and the noncanonical pyroptosis signalling pathway mediated by caspase-11.

Purpose To investigate the expression of bone sialoprotein(BSP)in the tissues and cells of endome-trial cancer(EC)and its effects on the proliferation and invasion of EC cells.Methods The expression of BSP was assessed by immunohistochemistry in 235 EC tissues and 88 normal endometrial tissues,and its correlation with clinico-pathological features was analyzed.Western blot was used to compare BSP levels between human endometrial carcinoma cell line(HHUA)and normal human endumetial epithelial cells(HEEC).BSP was knocked down in HHUA cells via transient transfection,and the cells were divided into blank control group and BSP-knockdown group.The effects of BSP knockdown on cell cycle,proliferation,migration,invasion,and apoptosis were evaluated using PI staining,CCK-8,scratch,Transwell,and Annexin V-FITC assays,respectively.Protein levels of TGF-β signaling pathway compo-nents were analyzed by Western blot.Results BSP expression was significantly higher in EC tissues than in normal endometrium(P＜0.001)and correlated with lymph node metastasis and advanced FIGO stage(P＜0.05).BSP pro-tein level was also significantly elevated in HHUA cells(2.455 8±0.008 9)compared to HEECs(1.571 2±0.005 4)(P＜0.01).After knockdown,compared with the control group,the proliferation index(74.4±3.33),migration rate(0.48±0.03),and invasion ability(0.36±0.11)of the cells were increased,and the apoptosis rate(25.97％)of the cells was increased(P＜0.05).Furthermore,the expression levels of TGF-β signaling pathway downstream proteins TGF-β1(0.290 4±0.002 3)、TGF-β2(0.292 9±0.001 6)、Smad2(0.469 3±0.001 1)、Smad3(0.247 0±0.001 7)、pAKT(0.382 1±0.001 9)、ATK(0.119 6±0.001 6)and MEK1(0.258 9±0.000 3)in the BSP-knockdown group of EC cells decreased(P＜0.01).Conclusion BSP is highly expressed in endometrial cancer and promotes cancer cell proliferation,invasion,and metastasis by activating the TGF-β signaling pathway.

Objective To explore the impact of enteral nutrition formula containing slow-release starch on blood glucose variability and prognosis in patients with severe acute pancreatitis(SAP).Methods A total of 204 SAP patients were enrolled and randomly divided into control group and ob-servation group using a random number table method,with 102 patients in each group.The control group received early enteral nutrition support with a standard enteral nutrition formula,while the ob-servation group received early enteral nutrition support with an enteral nutrition formula containing slow-release starch.Blood glucose variability indicators[largest amplitude of glycemic excursions(LAGE),standard deviation of blood glucose(SDBG),blood glucose coefficient of variation(BGCV),mean blood glucose(MBG),mean amplitude of glycemic excursions(MAGE),and time in range(TIR)]were compared between the two groups after treatment,along with clinical indicators during hospitalization,inflammatory markers[procalcitonin,C-reactive protein,interleukin-6(IL-6),and tumor necrosis factor-α(TNF-α)],and nutritional indicators(albumin,prealbumin)levels.Kaplan-Meier analysis was conducted to assess the prognosis of the two groups,and multivariate Cox regression analysis was performed to identify factors influencing prognosis.Results After treat-ment,the observation group exhibited lower levels of MBG,LAGE,SDBG,BGCV,MAGE,and a higher TIR compared with the control group(P＜0.05).During hospitalization,the observation group had a shorter duration of enteral nutritiontherapy,lower insulin usage,and lower incidence rates of multiple organ failure and infectious pancreatic necrosis compared with the control group(P＜0.05).After treatment,the observation group had lower levels of procalcitonin,C-reactive protein,IL-6,and TNF-α compared with the control group(P＜0.05);however,there were no statistically significant differences in albumin and prealbumin levels between the two groups(P＞0.05).Kaplan-Meier analysis showed that the cumulative mortality rate in the observation group was 12.75％,which was lower than the 17.65％in the control group(Log-rank x2=4.361,P=0.037).Multivariate Cox regression analysis revealed that TIR after treatment(HR=0.920;95％CI,0.869 to 0.974)was an independent protective factor for prognosis in SAPpatients(P＜0.05),while infectious pancreatic necrosis(HR=4.269;95％CI,1.922 to 9.482)was an inde-pendent risk factor for prognosis in SAP patients(P＜0.05).Conclusion Enteral nutrition formu-la containing slow-release starch helps stabilize blood glucose variability,control inflammatory mark-er levels,improve nutritional status,and prognosis in SAP patients.Both TIR and infectious pancre-atic necrosis are closely related to the prognosis of SAP patients.

Objective:To analyze the survival outcomes and prognostic factors of patients with ovarian carcino-sarcoma(OCS)based on SEER database.Methods:The data of 1285 OCS patients from 2000 to 2018 in SEER database were retrospectively analyzed.Univariate and multivariate Cox proportional hazards models were used to evaluate the prognostic factors associated with overall survival(OS)and cancer specific survival(CSS).Kap-lan-Meier survival curve was drawn to evaluate the survival analysis of patients' prognosis after clinical treatment.Results:①The study cohort included a total of 1285 OCS patients,The mean age of these patients was 66.21±11.71 years.Most patients had already experienced regional(22.80％)or distant(72.22％)metastasis at the time of diagnosis.②Multivariate Cox regression revealed,SEER stage of regional or distant metastasis,no surger-y,no chemotherapy,and no lymphadenectomy were independent risk factors for both patient OS and CSS(HR＞1,P＜0.05).Age ≥67 years was an independent risk factor for OS(HR＞1,P＜0.05).Age ≥ 83 years was an in-dependent risk factors for CSS(HR＞1,P＜0.05).③Kaplan-Meier survival analysis showed that among surgical patients with adjacent tissue invasion or distant metastasis had significantly better overall survival rate after lymph node dissection than those without(P＜0.001);We didn't see the significantly different effects of lymphadenecto-my on patients with localized disease(P=0.266).Among all patients who underwent surgery,the overall survival rate of all patients who received adjuvant chemotherapy after surgery was significantly better than that of those who did not(P＜0.001).Conclusions:Prognosis of OCS patients is associated with age,SEER comprehensive stage,surgery status,chemotherapy status,lymphadenectomy status.Patients with OCS who underwent cytore-ductive surgery and adjuvant chemotherapy had a better prognosis.However,it is questionable whether lymph-adenectomy is necessary in OCS patients with very early stage.

Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

Objective:To investigate the effects of remote ischemic preconditioning (RIPC) on myocardial injury after non-cardiac surgery (MINS) in elderly patients with hip fracture.Methods:A prospective randomized controlled trial was conducted on 78 elderly patients with hip fracture admitted to the Seventh Medical Center of the PLA General Hospital between October 2023 and September 2024. The patients were divided into RIPC group and non-RIPC group using a random number table. They were treated with closed reduction internal fixation, open reduction internal fixation, or hip arthroplasty for hip fracture under regional anesthesia. The RIPC group received RIPC intervention on the day before surgery and after entering the operating room on the day of surgery (3 cycles of 5-minute upper limb exsanguination followed by 5-minute reperfusion using an inflatable tourniquet cuff). The non-RIPC group received the same perioperative management as the RIPC group except RIPC. Plasma high-sensitivity cardiac troponin I (hs-cTnI) concentrations were measured at admission, immediately after surgery, on the morning of the first postoperative day, and on the morning of the third postoperative day and MINS incidence was calculated based on the hs-cTnI concentrations. The incidence of MINS within 3 days postoperatively and the intraoperative complications were compared in the overall cohort and in age-stratified groups (<80 years, ≥80 years). The local adverse reactions at the RIPC application sites were observed within 3 days after surgery.Results:Among the 78 elderly patients with hip fracture, including 21 males and 57 females, aged 60-99 years [79.5(70.0, 87.0)years], 40 were assigned to the RIPC group and 38 to the non-RIPC group. No significant difference was found in the general data of the two groups. There was no significant difference in the overall MINS incidence between the two groups ( P>0.05). In the patients aged <80 years, no MINS incidence was found (0/21) in the RIPC group, compared with 22% (4/18) in the non-RIPC group ( P<0.05), while in the patients aged ≥80 years, no significant difference in MINS incidence was observed between the two groups ( P>0.05). There were no significant differences in intraoperative complication rates in the overall cohort, patients aged <80 years, or patients aged ≥80 years ( P>0.05). None of the patients had local adverse reactions at the RIPC application sites. Conclusion:For elderly patients with hip fracture who received regional anesthesia, RIPC can significantly reduce the incidence of MINS in patients aged <80 years, but exerts no significant effect on MINS incidence in the overall cohort or in patients aged ≥80 years.
