RESUMO

OBJECTIVES: The diagnosis of tuberculosis otitis media (TBOM) remains a great challenge. This study aims to suggest potential diagnostic clues and proper management of TBOM. METHODS: The study is a retrospective review of TBOM cases that were treated at our department, between January 2015 and June 2023. Summarizing their clinical characteristics, diagnosis, and treatment. Additionally, a literature review is conducted. RESULTS: Eight cases of TBOM, 6 female and 2 male patients, median age was 32 years old, were included in the study. TBOM mainly presents with symptoms of otorrhea, hearing loss, and occasional early-onset facial palsy. One case had a positive Purified Protein Derivative (PPD) before the operation. Middle ear tissue was pathologically biopsied in 7 cases, with 3 cases testing positive for Acid Fast Bacillus and 6 cases testing positive for Mycobacterium tuberculosis PCR. Middle ear surgery and Anti-tubercular treatment (ATT) were completed in all cases. The median follow-up was 11 months. No cases of TB relapse were observed. CONCLUSIONS: Proper suspicion and confirmation of TBOM is the primary clinical orientation. Middle ear surgery combination with ATT results in satisfactory outcomes. Hearing reconstruction should be performed after ATT is completed.

RESUMO

Inflammation is associated with an increased risk of developing various cancers in both animals and humans, primarily solid tumors but also myeloproliferative neoplasms (MPNs), myelodysplastic syndromes (MDS), and acute myeloid leukemia (AML). Multi-walled carbon nanotubes (MWCNTs), a type of carbon nanotubes (CNTs) increasingly used in medical research and other fields, are leading to a rising human exposure. Our study demonstrated that exposing mice to MWCNTs accelerated the progression of spontaneous MOL4070LTR virus-induced leukemia. Additionally, similar exposures elevated pro-inflammatory cytokines such as interleukin (IL)-1ß, IL-6, and tumor necrosis factor (TNF)-α and induced reactive oxygen species (ROS) in a murine macrophage cell line. These effects were significantly reduced in immunodeficient mice and when mice were treated with methoxypolyethylene glycol amine (PEG)-modified MWCNTs. These findings underscore the necessity of evaluating the safety of MWCNTs, particularly for those with hematologic cancers.

RESUMO

An increasing number of studies have revealed a correlation between tertiary lymphoid structures (TLS) and the outcome of hepatocellular carcinoma (HCC). Nevertheless, the associations between the heterogeneity of cellular composition and the overall survival (OS) in HCC remain unexplored. Herein, we evaluated the cancer tissues from 150 HCC individuals treated at the Tumor Hospital Affiliated with Nantong University using multiplex immunofluorescence to determine the presence and characteristics of TLS and to investigate the relationship between intra-TLS immunologic activity, TLS maturation and intratumoral immune cell infiltration. Prognostic factors influencing the outcome were identified through both univariate and multivariate analyses. Additionally, the levels of cytotoxic T-lymphocyte antigen-4 (CTLA-4), programmed death 1 (PD-1), programmed death-ligand 1 (PD-L1) and lymphocyte activation gene-3 (LAG3) were determined, as well as their relationship with TLS features. TLS was detected in 71 (47.3%) of the 150 HCC cases and was related to higher intratumoral infiltration levels of lymphocytes. Additionally, intra-TLS lymphocyte proliferation correlated with that of intratumoral lymphocytes, and the presence of TLS and a high proportion of mature TLS demonstrated a significant correlation with better prognosis (p=0.013 and p=0.03, respectively). Among TLS-positive tumors, a high proportion of B-cells expressing activation-induced cytidine deaminase (AID) and a high proportion of CD8+ T-cells expressing CD45RO were significantly related to improved OS (p=0.01 and p<0.001, respectively). Comparatively, a high proportion of CD21+CD20+ B-cells demonstrated a significant correlation with poorer OS (p<0.002). A markedly reduced number of CTLA4+ cells in the stromal regions in TLS-negative tumors was observed compared to TLS-positive tumors (p=0.01). These findings reveal a correlation between TLS presence and improved OS in HCC patients. However, TLS exhibited significant variation in maturation state, T and B cell proliferation, and expression of markers related to B and T cell function. Notably, these characteristics were also found to possess prognostic significance, indicating that certain TLS might hinder tumor immunity by inhibiting immune cells while others may foster antigen-driven immune responses, likely influenced by the composition and functional status of intra-TLS lymphocytes.

RESUMO

BACKGROUND: Gastric cancer-related morbidity and mortality rates are high in China. Patients who have undergone gastric cancer surgery should receive six cycles of chemotherapy according to their condition. During this period, intestinal obstruction is likely to occur. Electrolyte balance disorders, peritonitis, intestinal necrosis, and even hypovolemic shock and septic shock can seriously affect the physical and mental recovery of patients and threaten their health and quality of life (QoL). AIM: To quantitatively explore the effects of enhanced recovery after surgery (ERAS)-based nursing on anxiety, depression, and QoL of elderly patients with postoperative intestinal obstruction after gastric cancer. METHODS: The clinical data of 129 older patients with intestinal obstruction after gastric cancer surgery who were treated and cared for in our hospital between January 2019 and December 2021 were examined retrospectively. Nine patients dropped out because of transfer, relocation, or death. According to the order of admissions, the patients were categorized into either a comparison group or an observation group according to the random number table, with 60 cases in each group. RESULTS: After nursing care, the observation group required significantly less time to eat for the first time, recover bowel sounds, pass gas, and defecate than the comparison group (P < 0.05). No significant difference was noted in nutrition-related indicators between the two groups before care. Before care, the Symptom Check List-90 scores between the two groups were comparable, whereas anxiety, depression, paranoia, fear, hostility, obsession, somatization, interpersonal sensitivity, and psychotic scores were significantly lower in the observation group after care (P < 0.05). The QoL scores between the two groups before care did not differ significantly. After care, the physical, social, physiological, and emotional function scores; mental health score; vitality score; and general health score were significantly higher in the observation group, whereas the somatic pain score was significantly lower in the observation group (P < 0.05). CONCLUSION: ERAS-based nursing combined with conventional nursing interventions can effectively improve patient's QoL, negative emotions, and nutritional status; accelerate the time to first ventilation; and promote intestinal function recovery in elderly patients with postoperative intestinal obstruction after gastric cancer surgery.

RESUMO

OBJECTIVE: To evaluate the reporting quality of randomized controlled trials (RCTs) of acupuncture for depression. METHODS: Systematic searches were performed in PubMed, the Cochrane Library, EMbase, CNKI, Wanfang, SinoMed and VIP Database for RCTs of acupuncture in treatment of depression. The search time was from the establishment of database to December 1, 2023, and the language restriction was Chinese and English. The reporting quality of RCTs of acupuncture for depression was evaluated using the CONSORT statement, the international standardization for trial reporting, STRICTA, the international standard for clinical trial interventions of acupuncture, and SHARE, the guideline and checklist for reporting sham acupuncture controls. RESULTS: According to the CONSORT statement items, the items with the reporting rate less than 50% was accounted for 54.05% of all of the items for Chinese articles, and there were 8 and 1 items with a reporting rate of 0% and 100%, respectively. For the English articles, the items with the reporting rate less than 50% was accounted for 35.14% of all of the items, and there were 3 and 7 items with a reporting rate of 0% and 100%, respectively. The reporting rate of 15 items in Chinese and English articles was greater than 50%, e.g. structured abstract, background and purpose. Based on STRICTA criteria, the reporting rate of either Chinese or English articles was relatively high. The items for Chinese articles with the reporting rate less than 50% was accounted for 23.53% of all of the items, and there were 1 and 4 items with a reporting rate of 0% and 100%, respectively. For English articles, the items with the reporting rate less than 50% was accounted for 11.76% of all of the items, and there was 1 item with a reporting rate of either 0% or 100%. In compliance with SHARE checklist, the reporting rate was low for either Chinese or English articles. The items with the reporting rate less than 50% was accounted for 57.89% of all of the items for Chinese articles, and there were 2 and 0 items with a reporting rate of 0% and 100%, respectively. For English articles, the items with the reporting rate less than 50% was accounted for 52.63% of all of the items, and there was 1 item with a reporting rate of 0% and 100%, respectively. CONCLUSION: The overall reporting quality of RCTs of acupuncture for depression is low currently. It is urgent to enhance the reporting of the details on sham acupuncture control especially. It is suggested that RCTs should be reported strictly in compliance with the CONSORT statement, STRICTA criteria, and SHARE checklist in the future.

RESUMO

Most nonconventional luminogens enjoy good water solubility and biocompatibility, showing unique application prospects in fields like biological imaging. Although clustering-triggered emission (CTE) mechanisms have been proposed to explain such emissions, the have not been thoroughly elucidated, which limits their development and application. Here, the photoluminescence properties of carboxymethyl ß-cyclodextrin (CM-ß-CD) aqueous solution are utilized to further investigate the effects of changes in concentration, in order to elucidate the emission mechanism through cryo-transmission electron microscopy (cryo-TEM), small-angle X-ray scattering (SAXS), molecular interaction analysis, and theoretical calculation. The results showed that the size distribution, morphology, and distance between water aggregates were successfully correlated with the cluster emission centers. The emission mechanism of nonconventional luminogen solutions was more clearly and intuitively elucidated, which has a promoting effect on the emission and application of this field. It is interesting that temperature-dependent emission spectra show the blue-shift phenomenon of PL with increasing excitation wavelengths. Moreover, due to its strong static quenching effect for Fe3+, CM-ß-CD can efficiently detect Fe3+ in mixed-ion aqueous solutions. It provides a strategy to clarify the CTE mechanism of nonconventional luminogen solutions more clearly and its application of mixed-ion detection.

RESUMO

OBJECTIVE: Colorectal cancer (CRC) is a form of malignancy that exhibits a comparatively elevated occurrence and fatality rate. Given the relatively slower progress in diagnostic and therapeutic approaches for CRC, there is a need to investigate more accurate and efficient biomarkers. METHODS: Core regulatory genes were screened using the TCGA database, and the expression of neurexophilin 4 (NXPH4) and its prognostic implications were validated using tissue microarray staining. The assessment of NXPH4 functions involved a range of experiments, including cellular, organoid, and murine models. Furthermore, a regulatory network between m5C, NXPH4, and HIF1A was established through several in vitro experiments. RESULTS: The overexpression of NXPH4 is associated with unfavorable prognoses in patients with CRC and hepatocellular carcinoma. Additionally, it facilitates the progression of malignant tumors both in laboratory settings and in living organisms of colorectal carcinoma. Our research also reveals that NXPH4 mRNA can avoid degradation through RNautophagy, relying on an m5C-dependent mechanism. Moreover, NXPH4 amplifies the HIF signaling pathway and stabilizes HIF1A by competitively binding to PHD4. CONCLUSIONS: NXPH4, regulated by m5C, promotes malignant tumor progression and regulates the HIF pathway. Consequently, targeting NXPH4 through molecular therapies could potentially serve as an efficacious therapeutic strategy for the management of CRC exhibiting elevated NXPH4 expression.

RESUMO

Dysfunction of voltage-gated sodium channel Nav1.2 causes various epileptic disorders, and inhibition of the channel has emerged as an attractive therapeutic strategy. However, currently available Nav1.2 inhibitors exhibit low potency and limited structural diversity. In this study, a novel series of pyrimidine-based derivatives with Nav1.2 inhibitory activity were designed, synthesized, and evaluated. Compounds 14 and 35 exhibited potent activity against Nav1.2, boasting IC50 values of 120 and 65 nM, respectively. Compound 14 displayed favorable pharmacokinetics (F = 43%) following intraperitoneal injection and excellent brain penetration potency (B/P = 3.6). Compounds 14 and 35 exhibited robust antiepileptic activities in the maximal electroshock test, with ED50 values of 3.2 and 11.1 mg/kg, respectively. Compound 35 also demonstrated potent antiepileptic activity in a 6 Hz (32 mA) model, with an ED50 value of 18.5 mg/kg. Overall, compounds 14 and 35 are promising leads for the development of new small-molecule therapeutics for epilepsy.

RESUMO

OBJECTIVES: To evaluate the predictive value of fasting plasma glucose (FPG) for in-hospital mortality in patients with acute myocardial infarction (AMI) with different glucose metabolism status. METHODS: We selected 5,308 participants with AMI from the prospective, nationwide, multicenter CAMI registry, of which 2,081 were diabetic and 3,227 were nondiabetic. Patients were divided into high FPG and low FPG groups according to the optimal cutoff values of FPG to predict in-hospital mortality for diabetic and nondiabetic cohorts, respectively. The primary endpoint was in-hospital mortality. RESULTS: Overall, 94 diabetic patients (4.5%) and 131 nondiabetic patients (4.1%) died during hospitalization, and the optimal FPG thresholds for predicting in-hospital death of the two cohorts were 13.2 mmol/L and 6.4 mmol/L, respectively. Compared with individuals who had low FPG, those with high FPG were significantly associated with higher in-hospital mortality in diabetic cohort (10.1% vs. 2.8%; odds ratio [OR] = 3.862, 95% confidence interval [CI]: 2.542-5.869) and nondiabetic cohort (7.4% vs. 1.7%; HR = 4.542, 95%CI: 3.041-6.782). After adjusting the potential confounders, this significant association was not changed. Furthermore, FPG as a continuous variable was positively associated with in-hospital mortality in single-variable and multivariable models regardless of diabetic status. Adding FPG to the original model showed a significant improvement in C-statistic and net reclassification in diabetic and nondiabetic cohorts. CONCLUSIONS: This large-scale registry indicated that there is a strong positive association between FPG and in-hospital mortality in AMI patients with and without diabetes. FPG might be useful to stratify patients with AMI.

RESUMO

BACKGROUND AND AIMS: Physical activity has proven effective in preventing atherosclerotic cardiovascular disease, but its role in preventing degenerative valvular heart disease (VHD) remains uncertain. This study aimed to explore the dose-response association between moderate to vigorous physical activity (MVPA) volume and the risk of degenerative VHD among middle-aged adults. METHODS: A full week of accelerometer-derived MVPA data from 87 248 UK Biobank participants (median age 63.3, female: 56.9%) between 2013 and 2015 were used for primary analysis. Questionnaire-derived MVPA data from 361 681 UK Biobank participants (median age 57.7, female: 52.7%) between 2006 and 2010 were used for secondary analysis. The primary outcome was the diagnosis of incident degenerative VHD, including aortic valve stenosis (AS), aortic valve regurgitation (AR), and mitral valve regurgitation (MR). The secondary outcome was VHD-related intervention or mortality. RESULTS: In the accelerometer-derived MVPA cohort, 555 incident AS, 201 incident AR, and 655 incident MR occurred during a median follow-up of 8.11 years. Increased MVPA volume showed a steady decline in AS risk and subsequent AS-related intervention or mortality risk, levelling off beyond approximately 300 min/week. In contrast, its association with AR or MR incidence was less apparent. The adjusted rates of AS incidence (95% confidence interval) across MVPA quartiles (Q1-Q4) were 11.60 (10.20, 13.20), 7.82 (6.63, 9.23), 5.74 (4.67, 7.08), and 5.91 (4.73, 7.39) per 10 000 person-years. The corresponding adjusted rates of AS-related intervention or mortality were 4.37 (3.52, 5.43), 2.81 (2.13, 3.71), 1.93 (1.36, 2.75), and 2.14 (1.50, 3.06) per 10 000 person-years, respectively. Aortic valve stenosis risk reduction was also observed with questionnaire-based MVPA data [adjusted absolute difference Q4 vs. Q1: AS incidence, -1.41 (-.67, -2.14) per 10 000 person-years; AS-related intervention or mortality, -.38 (-.04, -.88) per 10 000 person-years]. The beneficial association remained consistent in high-risk populations for AS, including patients with hypertension, obesity, dyslipidaemia, and chronic kidney disease. CONCLUSIONS: Higher MVPA volume was associated with a lower risk of developing AS and subsequent AS-related intervention or mortality. Future research needs to validate these findings in diverse populations with longer durations and repeated periods of activity monitoring.

RESUMO

INTRODUCTION: To investigate the autoinflammatory effect and biological behaviour of simvastatin (SIM) on adamantinomatous craniopharyngioma (ACP) cells. METHODS: Craniopharyngiomas imaging, intraoperative observations, and tumour histopathology were employed to investigate the correlation between esters and craniopharyngiomas. Filipin III fluorescent probe verified the validity of SIM on the alternations of synthesized cholesterol in craniopharyngioma cells. The cell counting kit-8 (CCK8) assay detected the impacts of SIM on cell proliferation and determined the IC50 value of tumour cells. Reverse transcription polymerase chain reaction (RT-PCR) measured the expression of inflammatory factors. Flow cytometry technique detected the cell cycle and apoptosis, and cell scratch assay judged the cell migration. Meanwhile, Western blot was adopted to determine the expression of proteins related to inflammation, proliferation, and apoptosis signalling pathways. RESULTS: In the ACP tumour parenchyma, many cholesterol crystalline clefts were observed, and the deposition of esters was closely associated with craniopharyngioma inflammation. After simvastatin intervention, a reduction in cholesterol synthesis within ACP was noted. RT-PCR analysis revealed SIM inhibited the transcription of inflammatory factors in ACP cells. Western blot analysis demonstrated SIM inhibited nuclear factor-kappa B (NF-κB) p65 activation expression while promoted the expressions of Cl-caspase-3 and P38 MAPK. CCK8 assay indicated a decrease in ACP cell activity upon SIM treatment. Scratch assay signified that SIM hindered ACP cell migration. Flow cytometry results suggested that the drug promoted ACP cell apoptosis. CONCLUSION: SIM suppressed the inflammatory response to craniopharyngiomas by inhibiting craniopharyngioma cholesterol synthesis, inhibited proliferation of ACP cells, and promoted their apoptosis.

RESUMO

Purpose: Tanshinone IIA (Tan-IIA) is widely used in patients with diabetic nephropathy (DN), but its protective effect on podocytes in DN has not been well studied. In this study, the effects of Tan-IIA on autophagy and inflammation of glomerular podocytes in DN were observed in vivo and in vitro, and the underlying mechanisms were investigated. Irbesartan, an angiotensin II receptor blocker, is a representative medication for the clinical treatment of DN. So irbesartan was chosen as a positive control drug. Methods: Eight-week-old male db/db mice were randomly divided into a DN group, an irbesartan group, and three groups receiving different doses of Tan-IIA. The control group consisted of the db/m littermate mice. Blood, urine, and kidney samples were taken from the mice after 12 weeks of continuous administration. Renal protection of Tan-IIA was evaluated using enzyme-linked immunosorbent assay kits, haematoxylin and eosin staining, transmission electron microscopy, Western blotting, and immunohistochemistry. In vitro, the protective effect of Tan-IIA on podocytes was explored using MPC5 cells cultured with high glucose. Results: Tan-IIA significantly improved renal pathological injury and relieved the renal dysfunction in DN. Compared with the DN group, Tan-IIA could up-regulate the expression of Synaptopodin, Podocin, LC3II/I and Beclin-1 (p < 0.05), and down-regulate the expression of p62, F4/80, NF-κB p65, IL-1ß, TNF-α and IL-6 (p < 0.05) both in vivo and in vitro, suggesting that Tan-IIA treatment alleviated podocyte injury by promoting autophagy and inhibiting inflammation during DN. The levels of p-PI3K/PI3K, p-Akt/Akt and p-mTOR/mTOR in Tan-IIA group were lower than those in DN group (p < 0.05), indicating that Tan-IIA inhibited the PI3K/Akt/mTOR signalling pathway in podocytes, which was a key pathway in regulating both autophagy and inflammation. Conclusion: Tan-IIA prevented podocyte injury in DN by fostering autophagy and inhibiting inflammation, at least in part via inhibition of the PI3K/Akt/mTOR signalling pathway.

RESUMO

BACKGROUND: Machine learning (ML) risk prediction models, although much more accurate than traditional statistical methods, are inconvenient to use in clinical practice due to their nontransparency and requirement of a large number of input variables. OBJECTIVE: We aimed to develop a precise, explainable, and flexible ML model to predict the risk of in-hospital mortality in patients with ST-segment elevation myocardial infarction (STEMI). METHODS: This study recruited 18,744 patients enrolled in the 2013 China Acute Myocardial Infarction (CAMI) registry and 12,018 patients from the China Patient-Centered Evaluative Assessment of Cardiac Events (PEACE)-Retrospective Acute Myocardial Infarction Study. The Extreme Gradient Boosting (XGBoost) model was derived from 9616 patients in the CAMI registry (2014, 89 variables) with 5-fold cross-validation and validated on both the 9125 patients in the CAMI registry (89 variables) and the independent China PEACE cohort (10 variables). The Shapley Additive Explanations (SHAP) approach was employed to interpret the complex relationships embedded in the proposed model. RESULTS: In the XGBoost model for predicting all-cause in-hospital mortality, the variables with the top 8 most important scores were age, left ventricular ejection fraction, Killip class, heart rate, creatinine, blood glucose, white blood cell count, and use of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs). The area under the curve (AUC) on the CAMI validation set was 0.896 (95% CI 0.884-0.909), significantly higher than the previous models. The AUC for the Global Registry of Acute Coronary Events (GRACE) model was 0.809 (95% CI 0.790-0.828), and for the TIMI model, it was 0.782 (95% CI 0.763-0.800). Despite the China PEACE validation set only having 10 available variables, the AUC reached 0.840 (0.829-0.852), showing a substantial improvement to the GRACE (0.762, 95% CI 0.748-0.776) and TIMI (0.789, 95% CI 0.776-0.803) scores. Several novel and nonlinear relationships were discovered between patients' characteristics and in-hospital mortality, including a U-shape pattern of high-density lipoprotein cholesterol (HDL-C). CONCLUSIONS: The proposed ML risk prediction model was highly accurate in predicting in-hospital mortality. Its flexible and explainable characteristics make the model convenient to use in clinical practice and could help guide patient management.

RESUMO

BACKGROUND: Chemotherapy for malignant tumors can cause brain changes and cognitive impairment, leading to chemotherapy-induced cognitive impairment (CICI). Current research on CICI has focused on breast cancer and Hodgkin's lymphoma. Whether patients with non-Hodgkin's lymphoma (NHL) undergoing chemotherapy have cognitive impairment has not been fully investigated. AIM: To investigate whether NHL patients undergoing chemotherapy had cognitive impairments. METHODS: The study included 100 NHL patients who were required to complete a comprehensive psychological scale including the Brief Psychiatric Examination Scale (MMSE) at two time points: before chemotherapy and within 2 wk of two chemotherapy courses. A language proficiency test (VFT), Symbol Number Pattern Test (SDMT), Clock Drawing Test (CDT), Abbreviated Daily Cognition Scale (ECog-12), Prospective and Retrospective Memory Questionnaire, and Karnofsky Performance Status were used to assess cognitive changes before and after chemotherapy. RESULTS: The VFT scores for before treatment (BT) and after treatment (AT) groups were 45.20 ± 15.62, and 42.30 ± 17.53, respectively (t -2.16, P < 0.05). The CDT scores were 8 (3.5-9.25) for BT and 7 (2.5-9) for AT groups (Z -2.1, P < 0.05). Retrospective memory scores were 13.5 (9-17) for BT and 15 (13-18) for AT (Z -3.7, P < 0.01). The prospective memory scores were 12.63 ± 3.61 for BT and 14.43 ± 4.32 for AT groups (t -4.97, P < 0.01). The ECog-12 scores were 1.71 (1.25-2.08) for BT and 1.79 (1.42-2.08) for AT groups (Z -2.84, P < 0.01). The SDMT and MMSE values did not show a significant difference between BT and AT groups. CONCLUSION: Compared to the AT group, the BT group showed impaired language, memory, and subjective cognition, but objective cognition and execution were not significantly affected.

RESUMO

China faces a healthcare challenge due to its aging population, necessitating an integrated old-age healthcare system considering multiple stakeholders' interests. Conflict and inequality may arise from varying stakeholder interests. This study develops a conflict resolution strategy for the coordination of stakeholders involved in the old-age healthcare service system, promoting harmonization and minimizing conflict to establish an equitable system meeting elderly needs. It contributes to a robust healthcare system for comprehensive, quality care. The focus of the study is to identify relevant stakeholders and decision-makers involved in developing an integrated old-age healthcare service system and explore a feasible solution through stakeholder analysis using the Mitchell score-based technique and stakeholder theory. Decision-makers' preferences are estimated using the Analytic Hierarchy Process (AHP). Solution strategies are developed through multiple stability concepts within the graph model for conflict resolution (GMCR). The conflict resolution analysis based on the integrated AHP-GMCR approach reveals that the development of an integrated old-age healthcare system is feasible by addressing potential conflicts among the stakeholders. Considering the current predicament of comprehensive medical services in China, governments should distribute authority, simplify procedures, and improve the insurance system. Furthermore, medical institutions should explore funding options, expand services, and enhance accessibility. Elderly individuals should prioritize healthy aging and seek suitable healthcare providers. Stakeholder participation is crucial for effective implementation. These recommendations enable China to advance integrated elderly care successfully, addressing challenges posed by the aging population.

RESUMO

Snakebite envenomation often induces acute kidney injury (AKI) and acute liver injury (ALI), leading to augmented injuries and poor rehabilitation. Phospholipase A2 (PLA2) and metalloproteinase (SVMP) present in venom are responsible for the envenomation-associated events. In this study, mice envenomed with Deinagkistrodon acutus, Naja atra, or Agkistrodon halys pallas venom exhibited typical AKI and ALI symptoms, including significantly increased plasma levels of myoglobin, free hemoglobin, uric acid, aspartate aminotransferase, and alanine aminotransferase and upregulated expression of kidney NGAL and KIM-1. These effects were significantly inhibited when the mice were pretreated with natural inhibitors of PLA2 and SVMP isolated from Sinonatrix annularis (SaPLIγ and SaMPI). The inhibitors protected the physiological structural integrity of the renal tubules and glomeruli, alleviating inflammatory infiltration and diffuse hemorrhage in the liver. Furthermore, the dual therapy alleviated oxidative stress and apoptosis in the kidneys and liver by mitigating mitochondrial damage, thereby effectively reducing the lethal effect of snake venom in the inhibitor-treated mouse model. This study showed that dual therapy with inhibitors of metalloproteinase and phospholipase can effectively prevent ALI and AKI caused by snake bites. Our findings suggest that intrinsic inhibitors present in snakes are prospective therapeutic agents for multi-organ injuries caused by snake envenoming.
