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 epidemiological characteristics of respiratory human adenovirus(H AdV)infections in hospitalized children in Ningbo,and to provide data for formulating infection prevention and control strategies for HAdV.METHODS A total of 65 022 children hospitalized with respiratory infections at the Women and Children's Hospital of Ningbo University from Jul.2019 to Dec.2024 were selected as the study sub-jects.Multiple reverse transcription-polymerase chain reaction(RT-PCR)and capillary electrophoresis were used to detect 11 non-bacterial pathogens.Basic and clinical information of the children was collected for analysis.RESULTS A total of 65 022 specimens were tested,with 4 292 cases tested positive for HAdV positivity,yielding a positive rate of 6.60％.The lowest positive rate was observed in 2023(3.22％),while the highest was in 2024(13.97％).Compared to the years 2019-2023,the overall HAdV positive rate was high in 2024,peaking at 26.80％in Jun.,indicating an outbreak.The total HAdV positive rate was higher in boys(6.82％)than in girls(6.32％)(P=0.006).The highest HAdV positive rate was observed in the 2 to＜6 age group(9.00％),while the lowest was in the 0 to＜1 age group(2.33％).Among the HAdV-positive specimens,2 658 cases(61.93％)were single infections,and 1 634 cases(38.07％)were co-infections.The non-bacterial respiratory pathogens with the highest co-infection rates were human rhinovirus(34.09％),Mycoplasma pneumoniae(20.44％)and human parainfluenza virus(5.75％).CONCLUSIONS A n outbreak of HAdV infections is observed among hospitalized children in Ningbo in 2024.Higher positive rates are found in boys aged 2 to＜6 years,with a certain proportion of co-infections.

AIM To establish a rapid quantitative analysis model for saponins in Paris polyphylla var.yunnanensis(PPY)by near infrared spectroscopy.METHODS The contents of polyphyllins Ⅰ,Ⅱ,Ⅶ and there total content in PPY were determined by HPLC,while spectral data within the range of 10 000 to 4 000 cm-1 were collected.A quantitative analysis model was established by combining these data with partial least squares regression(PLSR).Multivariate scatter correction(MSC)and vector normalization(SNV)were applied prior to further preprocessing the spectra with original,first-order derivative(1stD),or second-order derivative(2ndD)treatments.Lastly,the model was optimized through non-smoothing(NS),Norris Derivative filtering(Nd),and Savitzky-Golay filtering(S-G)method.Model stability was evaluated based on correlation coefficients and variance.The predicted contents of each saponin component in the validation set samples were calculated.RESULTS The contents of polyphyllins Ⅰ,Ⅱ,Ⅶ were 0.42-17.98,0.46-10.44,0.23-3.86 mg/g,respectively.The total content ranged from 2.91 to 22.1 mg/g.The optimal parameters of three saponins were achieved when selecting the MSC+2ndD+S-G pretreatment method.The corresponding ratio of line segment length to segment gap was 13∶5,15∶5,11∶5,with correlation coefficients of 0.982,0.930,0.958,respectively.The root mean square errors of calibration(RMSEC)were 0.702,0.797,0.238,and the root mean square errors of prediction(RMSEP)were 1.120,0.835,0.304,respectively.The optimal parameters for the total content were obtained when selecting the MSC+2ndD+NS pretreatment method,with a correlation coefficient of 0.970,a RMSEC of 1.090,and a RMSEP of 1.740.CONCLUSION This accurate and rapid method can be used for detection of saponin contents in P.Polyphylla.

OBJECTIVES: Anxiety is a common negative emotion. Under current social circumstances, university young teachers face multiple stressors and are more prone to anxiety, seriously threatening their physical and mental health. This study aims to investigate the impact of job insecurity on anxiety of university young teachers, while exploring the mediating roles of perceived stress and insomnia on this relationship. METHODS: Using convenience sampling, young teachers from a general university in a Chinese province were surveyed online. Scores of the Job Insecurity Scale, Perceived Stress Scale, Athens Insomnia Scale-Short Form, and Generalized Anxiety Disorder Scale were collected. A chain mediation analysis was conducted using the PROCESS macro. RESULTS: A total of 798 subjects were finally included. The detection rate of anxiety among university young teachers was 36.47%. Mediation analysis showed that job insecurity not only had a direct effect on anxiety, but also indirectly affected anxiety via perceived stress (46.42% of the total effect) and insomnia (7.45%), as well as through the chain-mediating path of perceived stress→ insomnia (13.18%; all P<0.05). CONCLUSIONS Job insecurity is a significant predictor of anxiety in young university faculty. Perceived stress and insomnia serve as sequential mediators in this relationship. Targeted interventions addressing job insecurity, stress perception, and sleep disturbances, alongside efforts to improve mental health literacy and the working environment, may help promote the overall well-being of university young teachers.

Purpose To explore the clinicopathological features,diagnosis and differential diagnosis of mantle cell lymphoma(MCL)with aberrant expression of CD10.Methods 14 cases of MCL with aberrant expression of CD10 were analyzed using hematoxylin-eosin,immunohistochemical stains,in situ hybridization,and fluorescence in situ hy-bridization(FISH)techniques to observe the histological morphology,immunophenotype,and molecular genetic char-acteristics.The relevant literatures were reviewed.Results There were 11 males and 3 females,with a male-to-fe-male ratio of 11∶3.The age ranged from 49 to 80 years,with an average age of 64.4 years and a median age of 64 years.10 cases occurred in lymph nodes,1 case in the nasopharynx,1 case in the right colon,1 case in the right eye-lid,and 1 case in the right testis.According to the Ann Arbor staging system,8 cases were classified as stage Ⅳ and 5 cases as stage Ⅲ,and 1 case with undetermined staging.Histologically,there was diffuse effacement of the normal architecture by tumor cells infiltration.Transparent degenerate small blood vessels and scattered individual epithelial-like tissue cells could be observed in the background.Among them,8 cases(8/14,57.14％)were composed of uni-form small to medium-sized lymphocytes with slightly irregular nuclei,unevenly dispersed chromatin,inconspicuous nucleoli,and scant cytoplasm,along with observable mitotic figures.In 3 cases(3/14,21.43％),the tumor cells were large and markedly pleomorphic,with round or irregular nuclei,prominent nucleoli,frequent mitotic figures,and abundant pale cytoplasm.Tumor cells in 3 cases(3/14,21.43％)were resembling lymphoblasts,characterized by round nuclei,fine chromatin,inconspicuous nucleoli,frequent mitotic figures,and scant cytoplasm.Immunophenotyp-ically,CD21 staining showed residual follicular dendritic meshworks.The tumor cells were diffusely and strongly posi-tive for CD20(14/14),PAX5(7/7),CD5(14/14),Cyclin D1(14/14),SOX11(11/11),and BCL2(13/13),partially positive for BCL6(8/14,57.14％)and MUM1(6/9,66.67％),but negative for CD3(14/14)and CD23(14/14).Among 14 cases,10 cases were diffusely and strongly positive for CD10(10/14,71.43％),and 4 cases were partially positive for CD10(4/14,28.57％).The percentage of Ki67 index ranged from 10％to 90％.All cases were negative for EBER(8/8).FISH analysis was performed in 9 cases,among which 7 cases showed CCND1 gene rearrangement,another 2 cases failed to detect due to insufficient tissue samples.Bone marrow biopsy was performed in 13 cases,revealing involvement in 8 cases(8/13,61.54％)and no involvement in 5 cases(5/13,38.46％).Con-clusion MCL with aberrant expression of CD10 is very rare,which commonly exhibits a diffuse growth pattern and blastoid and pleomorphic variants.It often has a high Ki67 proliferation index and poorer prognosis,and should be dis-tinguished from other subtypes of CD1O-positive B-cell lymphomas.

[Purpose]To analyze the incidence and mortality of thyroid cancer in Zhejiang cancer registration areas in 2021 and trends from 2000 to 2021.[Methods]Based on cancer data from 22 registries across Zhejiang Province between 2000 and 2021,the crude incidence/mortality rates,age-standardized incidence/mortality rates of thyroid cancer by Chinese and world standard population(ASIRC/ASMRC,ASIRW/ASMRW),cumulative rate(0～74 years old)and truncated rate(35～64 years old)were analyzed.Joinpoint regression model was employed to calculate the annual percentage change(APC)and average annual percentage change(AAPC)with 95％confidence in-terval(CI)for analyzing trends of thyroid cancer incidence and mortality rates from 2000 to 2021.[Results]The crude incidence rate of thyroid cancer increased from 3.62/105 in 2000 to 79.66/105 in 2021,and ASIRC rose from 3.11/105 to 69.49/105(AAPC=15.55％,95％CI:14.65％～16.61％).The AAPC for ASIRC was slightly higher in female(15.54％,95％CI:14.71％～16.49％)than that in male(15.02％,95％CI:13.53％～16.82％).The increase was significantly more pronounced in rural areas(AAPC=23.34％,95％CI:21.48％～25.33％)compared to urban areas(AAPC=14.12％,95％CI:13.15％～15.43％).Among age groups,the age group of 15～44 years old showed the fastest increase in crude incidence rate(AAPC=20.37％,95％CI:18.46％～22.31％),followed by the age group of 45～64 years old(AAPC=18.41％,95％CI:16.65％～20.19％).Between 2000 and 2021,the crude mortality rate of thyroid cancer rose from 0.34/105 to 0.56/105(AAPC=5.52％,95％CI:3.45％～7.70％),the trend of ASMRC was relatively stable.[Conclusion]From 2000 to 2021,the incidence of thyroid cancer in Zhejiang Province increased markedly,especially among females and younger to middle-aged adults,while the age-standardized mortality rate remained stable.

[Purpose]To analyze the incidence and mortality of colorectal cancer in Zhejiang can-cer registration areas in 2021 and its temporal trends from 2000 to 2021.[Methods]Data from 22 cancer registries in Zhejiang Province in 2021 that met the quality standards were included.The crude incidence/mortality rate,age-standardized incidence/mortality rates by Chinese standard population(ASIRC/ASMRC)and by world standard population(ASIRW/ASMRW),and cumulative incidence(mortality)rate for 0～74 years old were calculated.Trends from 2000 to 2021 were ana-lyzed using the Joinpoint regression model by calculating the annual percentage change(APC)and average annual percentage change(AAPC).[Results]In 2021,the number of new colorectal cancer cases in Zhejiang cancer registration areas was 12 265,with 4 323 deaths.ASIRC and ASMRC were significantly higher in men(32.74/105 and 10.11/105)than those in women(20.78/105 and 5.99/105).Urban areas showed higher ASIRC and ASMRC(28.27/105 and 8.06/105)than rural areas(24.12/105 and 7.85/105).The age-specific incidence and mortality rates of colorectal cancer in Zhejiang Province showed an increasing trend with age,with a peak of 219.63/105 in the age group of 80～84 years old.The age-specific mortality rate peaked in the age group of 85 years old and above,with a peak of 199.65/105.From 2000 to 2021,ASIRC in Zhejiang Province showed an upward trend(AAPC=2.23％,P＜0.001),ASMRC showed a marginal increase(AAPC=0.78％,P=0.067).[Conclusion]The incidence of colorectal cancer in Zhejiang Province had been on a continuous rise in the past 22 years,and health education and early screening should be empha-sized.

Objective:To report the preclinical trial results of the application of a domestic high-flow percutaneous left ventricular assist device (pLVAD) in patients with low cardiac output syndrome (LCOS) following cardiac surgery.Methods:Six patients who developed LCOS after direct cardiac surgery were implanted with a domestic high-flow pLVAD. Clinical outcomes, including hemodynamic changes, complications, and survival rates were observed post-implantation.Results:Four patients underwent pLVAD implantation under digital subtraction angiography (DSA) guidance, while two patients had the procedure performed under ultrasound guidance. The implantation process was straightforward, rapid, and uneventful, with no instances of bleeding or arrhythmias. The flow rate at the initiation of pLVAD support was 3.8-5.0 (4.22±0.44)L/min, and the flow rate during pump removal was 1.0-1.3(1.18±0.15)L/min. The duration of pLVAD support was 16.5-165.0(101.3±60.65)h. Hemodynamic parameters showed immediate improvement following pLVAD support: mean arterial pressure increased from (62.67±4.46)mmHg to (80.50±18.96)mmHg (1 mmHg=0.133 kPa, P=0.049), cardiac output increased from (2.45±0.66)L/min to (4.35±1.32)L/min( P=0.01), cardiac index improved from (1.95±0.21)L·min -1·m -2 to (2.77±0.33)L·min -1·m -2( P<0.001), pulmonary artery diastolic pressure decreased from (27.50±1.87) mmHg to(18.33±4.18)mmHg( P=0.001), and left ventricular ejection fraction improved from 0.27±0.04 to 0.37±0.06 ( P=0.004). No visible hemoglobinuria was noted during the support period. No malignant arrhythmias or cerebrovascular complications occurred. One patient required transition to surgical LVAD implantation, while the other five patients had the pLVAD successfully removed and were discharged. Three months later, all six patients were alive, with functional status classified as New York Heart Association (NYHA) Class Ⅰ-Ⅱ. Conclusion:The implantation of a domestic high-flow pLVAD provides a safe and effective therapeutic option for patients with LCOS following cardiac surgery.
