Nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) is a cytosolic pattern recognition receptor that recognizes multiple pathogen-associated molecular patterns and damage-associated molecular patterns. It is a cytoplasmic immune factor that responds to cellular stress signals, and it is usually activated after infection or inflammation, forming an NLRP3 inflammasome to protect the body. Aberrant NLRP3 inflammasome activation is reportedly associated with some inflammatory diseases and metabolic diseases. Recently, there have been mounting indications that NLRP3 inflammasomes play an important role in liver injuries caused by a variety of diseases, specifically hepatic ischemia/reperfusion injury, hepatitis, and liver failure. Herein, we summarize new research pertaining to NLRP3 inflammasomes in hepatic injury, hepatitis, and liver failure. The review addresses the potential mechanisms of action of the NLRP3 inflammasome, and its regulation in these liver diseases.

Objective: To investigate the molecular mechanisms and pathways of action of total flavonoids of Dracocephalum moldavica L.(TFDM) in treating vascular cognitive impairment(VCI) based on network pharmacology and in vivo animal experiments. Methods : The swiss target prediction database, literature, and PubChem were used to screen the active components and action targets of TFDM. The online mendelian inheritance in man(OMIM) and GeneCards databases were utilized to screen for possible VCI targets. Venny software was used to obtain the intersection target of TFDM and VCI. The search tool for recurring instances of neighbouring genes(String) database and Cytoscape software was used to construct the PPI network. The database for annotation, visualization and integrated discovery(DAVID) database was utilized to screen for the kyoto encyclopedia of genes and genomes(KEGG) pathway and gene ontology(GO) enrichment analyses to explore the molecular mechanism and signaling pathway of TFDM for VCI. 24 rats were divided into Sham, Model, Donepezil, and TFDM groups. Except for the Sham group, the VCI model was created using modified bilateral common carotid artery ligation. After continuous gavage for 21 days, the Morris water maze test was used to evaluate the spatial learning and memory ability of rats. Hematoxy-lineosin(HE) staining was used to observe the pathological changes in the hippocampal CA1 and cortex region of the animals and immunohistochemistry detection of zonula occludens-1(ZO-1) content in the brains of the rats. Western blot was used to detect nuclear factor kappa-B p65(NF-κB p65) and tumor necrosis factor-α(TNF-α) in rat brains. Results : A total of 39 active ingredients of TFDM were screened, 209 corresponding targets, 10 417 gene targets of VCI, and 193 intersecting targets. According to the results of the GO enrichment of function analysis, TFDM could improve the response of reactive oxygen species and metabolic processes of reactive oxygen species, etc. KEGG pathway enrichment analysis suggested that TFDM might regulate TNF, IL-17 signing pathway, etc. The results of animal experiments showed that TFDM improved learning and memory while reduced pathological damage in the brains of VCI rats. In addition, TFDM upregulated the positive expression of ZO-1 and downregulated the protein levels of TNF-α and NF-κB p65(P<0.05). Conclusion TFDM can improve the cognitive function of VCI through multi-components and multi-targets, and its key mechanism may be related to inhibiting TNF-α/NF-κB p65 signaling pathway,reducing neuroinflammation,and improvement of blood-brain barrier permeability.

Objective To investigate the predictive ability of cyst fluid characteristics for malignant intraductal papillary mucinous neoplasms (IPMNs). Methods We prospectively collected fresh cyst fluid from patients undergoing pancreatic resection at the Department of Hepatobiliary Pancreatic Spleen Surgery, Changhai Hospital, Shanghai, from September 2023 to December 2024, who were ultimately pathologically confirmed with IPMN. We assessed the characteristics of cyst fluid, including viscosity, clarity, and color, and explored its predictive performance for benign or malignant. Results A total of 40 patients with IPMN were included. The sensitivity of the string sign （+） for diagnosing high-grade dysplasia/ invasive carcinoma （HGD/IC） was 90.9%, specificity was 92.9%, and accuracy was 76.0%. The cyst fluid of intestinal-type IPMN often exhibited a gelatinous consistency, and there was no significant difference in the distribution of gelatinous consistency between the HGD/IC group and the low-grade dysplasia （LGD） group. There were no significant differences in CEA, glucose, and amylase levels in the cyst fluid between the HGD/IC group and the LGD group. Conclusions The characteristics of pancreatic cyst fluid, especially viscosity, can effectively predict the benign or malignant nature of IPMN.

Objective To analyze the risk factors for moderate-to-severe coronary artery stenosis in the population of Tacheng,Xinjiang Uygur Autonomous Region,and to construct and verify a nomogram prediction model for the degree of coronary artery ste-nosis.Methods We retrospectively selected 629 patients who were hospitalized in the Cardiovascular Department of Tacheng Peo-ple's Hospital from January 2021 to June 2023.Using R language software,the sociodemographic data,disease-related data,and va-rious laboratory indicators of the 629 patients were included in the initial screening of risk factors for use in the LASSO regression analysis using a random number table method.The 629 patients were divided into a training group(n=440)and a validation group(n=189)in a 7:3 ratio.Data from the training group were used for model construction,with the degree of coronary artery stenosis as the dependent variable,and the variables selected by LASSO regression as independent variables in the logistic regression model.The validation group was used for model validation.Based on the results of the logistic regression analysis,a visual nomogram for predicting the degree of co-ronary artery stenosis was constructed using R language software.The discriminability,calibration,and clinical utility of the model were evaluated using the area under the receiver operating characteristic curve(AUC),a calibration curve,and decision curve analysis(DCA).Results Age,non-Han ethnicity,hypertension,hyperlipidemia,and a history of cerebrovascular disease were risk factors for mode-rate-to-severe coronary artery stenosis and were included in the risk prediction model.The AUC of the training group and the validation group were 0.905(95％CI:0.790-0.863)and 0.864(95％CI:0.744-0.861),respectively.The predicted values of the calibration curve were consistent with the actual values(Brier scores of the training and validation group:0.03 and 0.14,respectively).The predictive per-formance of the model was good,and the DC A results indicated that the model had net clinical benefits.Conclusion The risk prediction model for coronary artery stenosis in the population of the Tacheng area constructed in this study has good predictive performance and can provide a simple,feasible,economical,and easy-to-promote evaluation tool for medical personnel to screen patients with moderate-to-se-vere coronary artery stenosis.

Objective:To analyze the prevalence trends and epidemiological characteristics of cardiometabolic multimorbidity(CMM) in Beijing from 2005 to 2022.Methods:A series of representative cross-sectional surveys were conducted in Beijing between 2005 and 2022 using a stratified multistage cluster random sampling method. A total of 110 496 permanent residents aged 18-79 years participated in face-to-face interviews, physical examinations, and laboratory testing. Complex sampling logistic regression models were employed to identify factors associated with CMM, and Joinpoint regression was used to assess temporal trends in prevalence. Results:The prevalence of CMM was 22.3% in 2005 and 24.3% in 2022, with an average annual percent change of 0.1%(95% CI -1.3%-1.3%, P>0.05). In rural areas, the prevalence increased by 1.3% per year(95% CI 0.2%-2.6%, P<0.05), while among obese individuals, it decreased by 1.0% annually( P<0.05). The most common CMM patterns were hypertension combined with dyslipidemia(13.2%), hypertension combined with diabetes(7.0%), and diabetes combined with dyslipidemia(5.8%). The prevalence of hypertension and dyslipidemia comorbidity showed a long-term decline among females, those aged 60-79 and obese individuals( P<0.05). In contrast, the prevalence of hypertension and diabetes comorbidity increased over time in rural residents and individuals with normal body weight( P<0.05). Furthermore, diabetes and dyslipidemia comorbidity rates increased significantly among males, adults aged 18-59 years, those with a college education or above, rural residents and individuals with normal body weight( P<0.05). Multivariable logistic regression indicated that male, older age, overweight, obese, and lower education level were independently associated with a higher risk of CMM( P<0.05). Conclusion:From 2005 to 2022, the prevalence of CMM remained high among adults in Beijing. While prevalence decreased among obese individuals, it increased significantly in rural areas. Hypertension combined with dyslipidemia was the most common multimorbidity pattern throughout the study period.

Objective:To explore the clinical characteristics of adrenal lesions in unilateral primary aldosteronism.Methods:This is a prospective study. Consecutive patients diagnosed with unilateral primary aldosteronism at the First Affiliated Hospital of Chongqing Medical University from December 2023 to November 2024 were included. Inclusion criteria：① Age is 18 to 80 years old；② The laboratory test indicators are in line with the diagnosis of primary aldosteronism；③ The auxiliary examination proved that only one side was involved；④ Patient undergo unilateral total adrenalectomy. The exclusion criteria are as follows：① Complete biochemical remission was not achieved during the 1-6 month follow-up after the surgery；② Postoperative loss to follow-up；③ No surgical specimens were received or the surgical specimens were incomplete，making continuous sectioning impossible. Patients meeting the inclusion criteria were recruited，and their clinical and biochemical data were recorded. The number of adrenal nodules visible on CT scans and the number of macroscopically visible nodules in the postoperative adrenal gross specimens were documented. Hematoxylin-eosin（HE）staining and aldosterone synthase CYP11B2 immunohistochemical staining were performed on the adrenal tissues after the operation. The number of nodules visible under the light microscope and the number of CYP11B2-positive nodules were recorded.Results:A total of 114 cases were included in this study. The age of the patients was（49.86 ± 9.80）years，the body mass index was（25.49 ± 3.40）kg/m2，the preoperative aldosterone level was 352（2012，556）pg/ml，and the direct renin concentration was 1.63（0.50，4.56）μIU/ml. The aldosterone/renin ratio was 224.9（57.1，641.6）（aldosterone concentration unit was pg/ml，renin concentration unit was μIU/ml），the minimum blood potassium concentration was 2.87（2.50，3.40）mmol/L，and the systolic blood pressure was（144.5 ± 19.5）mmHg. Among the 114 patients，105 had adrenal nodules detected by preoperative CT，of whom 2（1.75%）had multiple nodules. Postoperative gross adrenal specimen evaluation and CYP11B2 immunohistochemical staining revealed that 90 out of 114 cases were solitary nodules，2 cases had no nodules，and 22 cases（19.30%）had multiple nodules detected（17 cases had 2 nodules and 5 cases had 3 nodules）. Among them，12 cases（10.53%）presented as grossly visible multinodular lesions，while 10 cases（8.77%）appeared as solitary nodules macroscopically but demonstrated multinodular patterns on immunohistochemical staining. CYP11B2 staining showed that among the 22 patients with multiple nodules，13 had multiple CYP11B2-positive nodules，while the remaining had only one positive nodule. Among the 22 patients with multiple nodules，preoperative CT showed single nodules in 19 cases，hyperplasia in 1 case，and multiple nodules in 2 cases（9.09%）. Among the 12 patients with grossly visible multinodular lesions，preoperative CT showed single nodules in 9 cases，hyperplasia in 1 case，and multiple nodules in 2 cases（16.67%）.Conclusions:Multiple adrenal nodules associated with unilateral primary aldosteronism are relatively common，and are often not detected by preoperative CT examination. Partial adrenalectomy based solely on CT-visible nodules may fail to achieve complete remission of primary aldosteronism. This study provides evidence supporting total adrenalectomy as the preferred surgical approach for unilateral primary aldosteronism.

Objective To investigate the correlation between apathy and imaging markers in pa-tients with aCSVD.Methods A total of 143 patients diagnosed with aCSVD and hospitalized in the Department of Neurology of the First Affiliated Hospital of Baotou Medical College,Inner Mongolia University of Science and Technology from August 2023 to August 2024 were continu-ously included as the study objects.According to MAES,they were divided into an apathetic group(MAES score＞14,68 cases)and a non-apathetic group(MAES score ≤14,75 cases).The clinical data and imaging markers were compared between the two groups.Results The apathetic group had significantly older age and larger ratio of hypertension,but shorter years of education and lower MAES score than the non-apathetic group(P＜0.05,P＜0.01).The apathetic group also had notably higher Fazekas score of white matter hyperintensity(WMH),larger recent small sub-cortical infarct(RSSI),lacunar infarct(LI),and perivascular space(PVS)in the basal ganglia and the centrum semiovale,more obvious cerebral atrophy and cerebral microbleed(CMB),and high-er total imaging burden score when compared with the non-apathetic group(P＜0.01).In the aCSVD patients,the MAES score was positively correlated with WMH Fazekas score,RSSI,LI,basal ganglia PVS,centrum semiovale PVS,cerebral atrophy,CMB,and total imaging burden score(P＜0.01).WMH Fazekas score was an independent risk factor for apathy in the aCSVD patients(OR=2.218,95％CI:1.343-3.664,P=0.002).Conclusion The higher the score of ima-ging markers in patients with aCSVD,the more severe the apathy.

Objective:To investigate the related factors of cognitive impairment in middle-aged and old-aged patients with type 2 diabetes mellitus(T2DM).Methods:A total of 970 patients with T2DM(585 middle-aged group and 385 old-aged group)were selected from residents of a large community in Beijing from September to December 2018.The Mini-Mental State Examination(MMSE)was used to assess the cognitive func-tion.Multivariate logistic regression was used to analyze the related factors.Results:The detection rates of cognitive impairment were 12.0％and 13.5％in middle-aged and old-aged patients with T2DM,respectively.Among mid-dle-aged patients with T2DM,work(OR=0.22,95％CI:0.03-0.77)and education at the junior college or un-dergraduate level and above(OR=0.18,95％CI:0.04-0.55)were protective factors for cognitive impair-ment.Myocardial infarction(OR=4.13,95％CI:1.26-13.63)was a risk factor for cognitive impairment.Among old-aged patients with T2DM,drinking tea 1-2 times a week(OR=0.11,95％CI:0.01-0.58)and education at the junior college or undergraduate level and above(OR=0.19,95％CI:0.05-0.54)were protective factors for cognitive impairment.Stroke(OR=3.64,95％CI:1.55-8.39)and good sleep self-assessment(OR=2.75,95％CI:1.13-7.35)were risk factors for cognitive impairment.Conclusion:Cognitive impairment in middle-aged pa-tients with T2DM is related to work,education level and myocardial infarction,and cognitive impairment in old-aged patients with T2DM is related to lifestyle,education level and stroke.

Objective:To construct a humanistic care nursing program for adult ICU patients, providing guidance for the clinical practice of humanistic care in ICUs.Methods:Based on a literature review and clinical practice experience, a preliminary humanistic care nursing program for adult ICU patients was drafted. From August to September 2024, the Delphi method was used to conduct two rounds of expert consultation with 16 experts to revise the content of each item and the overall program, resulting in the final version of the humanistic care nursing program for ICU adult patients. The experts' engagement was measured by the effective response rate of the questionnaires, their authority by the expert authority coefficient, and the coordination of expert opinions by the Kendall's coefficient of concordance.Results:The effective response rate for the Delphi expert consultation questionnaires was 100.00% (16/16) in both rounds. The expert authority coefficients were 0.872 and 0.875, respectively. After the second round of consultation, the Kendall's coefficients for the importance, applicability, and feasibility of each level of item ranged from 0.119 to 0.313 ( P<0.05). The final humanistic care nursing program for adult ICU patients included three first-level items, 12 second-level items, and 55 third-level items. Conclusions:The humanistic care nursing program for adult ICU patients constructed in this study is scientific, targeted, and feasible, providing guidance for the clinical practice of humanistic care in ICU settings.
