ObjectiveTo analyze the satisfaction of service recipients with the preliminary assessment service of the unified elderly care needs evaluation in Shanghai， so as to provide reference for further optimization of the service system. MethodsA multi-stage random sampling method was employed to recruit participants. A total of 110 individuals who had received unified elderly care needs evaluation service in six districts of Shanghai were investigated using a structured questionnaire. SPSS 25.0 was used to analyze the data. Univariate analyses were conducted using the Chi-square test and Fisher’s precision probability test， while multivariate analysis was performed using ordinal regression. ResultsThere were differences in satisfaction with various aspects of the preliminary assessment process among participants from different areas， with those from outer suburbs generally exhibiting lower satisfaction （P<0.01）. Multivariate analysis results indicated that satisfaction with the timing of the preliminary assessment was related to the service recipients’ residential area and their primary source of income； satisfaction with the service attitude and capability of the assessment personnel was only related to the residential area. Satisfaction with the preliminary evaluation results was related to the participants’ marital status， educational level， income level， and the specific rating results. ConclusionThe satisfaction level with the preliminary assessment of the unified elderly care needs assessment in Shanghai is relatively high. In the process of evaluation， a deeper analysis and exploration of individual needs based on various personal information are essential to ensure the appropriateness of the provided elderly care services， and thereby effectively enhancing recipient satisfaction.

MethodsA survey was conducted among 93 assessment personnel randomly selected from 29 elderly care needs assessment agencies in Shanghai. The personnel’s perception of their work and their levels of job satisfaction were examined. Chi-square test and Fisher’s precision probability test were used to compare regional differences， while the two-factor theory was employed to analyze the factors influencing job satisfaction. ResultsRegarding perception of the work， 92.5% of the surveyed personnel believed their work was important. Moreover， 87.1% were interested in their assessment tasks， and 84.9% believed they made a positive contribution to the assessment work and the assessment position was in line with their personal preferences. Regarding job satisfaction， 83.9% of the participants were satisfied with their assessment work， 78.5% considered the workload appropriate， and 74.2% found the working hours suitable. Additionally， 65.6% expressed satisfaction with the level of cooperation from the assessment subjects， while 94.6% and 91.4% of the personnel were satisfied with the support provided by the assessment agencies and had a sense of belonging， respectively. Furthermore， 65.6% of the personnel expressed satisfaction with their job compensation and benefits. Hygiene factors affecting job satisfaction included salary and compensation， workload， time spent on the job and institutional support related to external assistance， job suitability， teamwork， and client cooperation （P<0.05）， while motivational factors included recognition of the significance of the job， sense of achievement， interest in the job， sense of belonging， and opportunities for personal growth （P<0.05）. ConclusionThe overall work cognition and satisfaction of unified elderly care needs assessment personnel in Shanghai towards their work are relatively positive. Main issues include the heavy workload and actual job subsidies not meeting expectations. It is recommended to improve the standardization of the assessment process， establish a professional team of assessment personnel， and enhance the compensation and incentive mechanisms to continuously increase staff satisfaction.

Objective:To evaluate the impact of orthopedic robotic assistance and conventional freehand methods on surgical strategies, the safety of pedicle screw placement, and clinical efficacy in patients with upper cervical spine diseases.Methods:From January 2017 to March 2023, a total of 63 cases with upper cervical spine disease, were divided into two groups based on the screw placement technique: the robot-assisted pedicle screw placement (RA) group (41 cases) and the conventional freehand pedicle screw placement (CF) group (22 cases), were retrospectively included. These patients in the RA and CF groups underwent two types of posterior cervical surgery, including occipitocervical fusion (9 cases and 8 cases) and fixation and fusion of atlantoaxial and distal vertebrae (32 cases and 14 cases). The outcome parameters, including the disease course, surgical time, intraoperative blood loss, fluoroscopy frequency, radiation dose, hospital stay, treatment costs, complications, the rate of the pedicle screw placement, accuracy of upper cervical pedicle screw placement, and the risk factors that possibly affected the accuracy were recorded and analyzed. Postoperative follow-up was conducted for at least 6 months, and the efficacy of patients was assessed using imaging parameters, ASIS classification, VAS, and JOA scores.Results:Both groups had no screw-related complications and no spinal cord or vertebral artery injuries. In the RA group, the pedicle screw placement rates for the patients with occipitocervical fusion, and fixation and fusion of atlantoaxial and distal vertebrae were 100% (48/48) and 89.6% (138/154), respectively, far exceeding the placement rate in the CF group 42.9% (18/42) and 78.3% (54/69) (χ 2=37.403, P<0.001; χ 2=5.128, P=0.024). The fluoroscopic exposure dose and operation time of the two types of surgical patients in the RA group were both higher than those in the CF group ( P<0.05). Compared with the CF group, the accuracy of C 1 screws in the RA group increased from 42% (11/26) to 80% (51/64), with statistical significance (χ 2=13.342, P=0.004); while the accuracy of C 2 screws improved from 77% (33/43) to 88% (63/72) with no statistical difference (χ 2=2.863, P=0.413). Non-parametric correlation analysis found a significant correlation between the accuracy of C 1 and C 2 pedicle screw placement and the order of guide wire insertion in the RA group ( r=0.580, P<0.001; r=0.369, P=0.001). Postoperatively, both groups showed significant differences in cervicomedullary angle (CMA), Chamberlain angle (CL), McGregor angle, Boogard angle, Bull angle, clivus-canal angle (CCA), occipitocervical (C 0-C 2) angle, posterior occipitocervical angle (POCA), C 2-C 7 angle, and anterior atlantodental interval (ADI) ( P<0.05). The ASIA classification improved to varying degrees for both groups postoperatively, but there were no statistically significant differences between preoperative, postoperative, and last follow-up evaluations. VAS and JOA scores significantly improved for both groups postoperatively and at the last follow-up ( P<0.05). Conclusion:Both orthopedic robotic-assisted and conventional freehand pedicle screw placement techniques achieved satisfactory therapeutic effects in the treatment of upper cervical spine diseases. The orthopedic robot can effectively ensure the accuracy of upper cervical pedicle screw placement, the increase placement rate of pedicle screws in the upper cervical spine, and reduce fluoroscopy exposure. However, it is necessary to avoid the vertebral displacement caused by the priority insertion of the guide needle, which may affect the accuracy of subsequent planning.

ObjectiveTo explore the mechanism of Buzhong Yiqitang in ameliorating inflammatory injury in autoimmune thyroiditis (AIT) mice based on the Toll-like receptor 4（TLR4）/nuclear transcription factor-kappa B（NF-κB）/absent in melanoma 2（AIM2）inflammasome signaling pathway. MethodThe 120 genetically susceptible 8-week-old NOD.H-2^h4 mice were selected and randomly divided into control group， model group， low， medium and high dose groups of Buzhong Yiqitang （4.78， 9.56， 19.12 g·kg^-1）， and western medicine group （selenium yeast tablets， 3.033×10^-5 g·kg^-1）. The AIT model mice in each group drank ad libitum 0.05% sodium iodide aqueous solution for 8 weeks to establish the AIT model， and the control group drank ad libitum distilled water. Eight weeks later， the mice in each dosing group were divided into groups and gavage. The swelling of thyroid tissue was observed with the naked eye， and the weight of spleen was weighed. The content of serum inflammatory factors interleukin-1β （IL-1β）， interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α） was measured by enzyme-linked immunosorbent assay （ELISA）， and Real-time PCR was used to detect the expression of HMGB1， TLR4， AIM2， NF-κB p65，apoptosis-associated speck-like protein（ASC），cysteinyl aspartate-specific protease-1（Caspase-1）， IL-1β mRNA. Western blot was used to detect the expression of high motility group protein 1 （HMGB1）， TLR4， AIM2， NF-κB p65， phosphorylation（p）-NF-κB p65， ASC， Caspase-1， and IL-1β proteins in thyroid tissue， and immunofluorescence staining was used to observe the protein expression of HMGB1， AIM2， and NF-κB p65 in thyroid tissue of mice. ResultCompared with the control group， the thyroid tissue of mice in the model group was significantly swollen， the spleen quality was significantly increased， and the expression of HMGB1， TLR4， NF-κB p65， AIM2， ASC， Caspase-1， IL-1β in thyroid tissue was significantly increased （P<0.01）. Compared with the model group， the swelling of thyroid tissue in mice in each dose group of Buzhong Yiqitang was improved， the quality of spleen was significantly reduced， and the expression of HMGB1， TLR4， AIM2， NF-κB p65， p-NF-κB p65， ASC， Caspase-1， IL-1β in thyroid tissue was significantly reduced （P<0.05， P<0.01）. ConclusionBuzhong Yiqitang can effectively improve the inflammatory injury of AIT， and regulating the abnormal activation of the TLR4/NF-κB/AIM2 inflammasome signal pathway may be one of its intervention mechanisms.

Tripterygium glycosides tablet(TGT),the classical commercial drug of Tripterygium wilfordii Hook.F.has been effectively used in the treatment of rheumatoid arthritis,nephrotic syndrome,leprosy,Behcet's syndrome,leprosy reaction and autoimmune hepatitis.However,due to its narrow and limited treatment window,TGT-induced organ toxicity(among which liver injury accounts for about 40％of clinical reports)has gained increasing attention.The present study aimed to clarify the cellular and molecular events underlying TGT-induced acute liver injury using single-cell RNA sequencing(scRNA-seq)technology.The TGT-induced acute liver injury mouse model was constructed through short-term TGT exposure and further verified by hematoxylin-eosin staining and liver function-related serum indicators,including alanine aminotransferase,aspartate aminotransferase,alkaline phosphatase and total bilirubin.Using the mouse model,we identified 15 specific subtypes of cells in the liver tissue,including endothelial cells,hepatocytes,cholangiocytes,and hepatic stellate cells.Further analysis indicated that TGT caused a significant inflammatory response in liver endothelial cells at different spatial locations;led to marked inflammatory response,apoptosis and fatty acid metabolism dysfunction in hepatocytes;activated he-patic stellate cells;brought about the activation,inflammation,and phagocytosis of liver capsular macrophages cells;resulted in immune dysfunction of liver lymphocytes;disturbed the intercellular crosstalk in liver microenvironment by regulating various signaling pathways.Thus,these findings elaborate the mechanism underlying TGT-induced acute liver injury,provide new insights into the safe and rational applications in the clinic,and complement the identification of new biomarkers and ther-apeutic targets for liver protection.

Objective:To evaluate the quality of life (QoL) of Chinese chronic pancreatitis (CP) patients based on the Chinese version of the pancreatitis quality of life Instrument (PANQOLI) and explore its impact factors.Methods:404 patients with CP admitted to the Department of Gastroenterology of the First Affiliated Hospital of Naval Medical University between September 2021 and January 2022 were enrolled. The Chinese version of PANQOLI was used for questionnaire survey on QoL of CP patients. Univariate analysis and multiple linear regression analysis were used to explore the impact factors for QoL of CP patients.Results:The total score of QoL of 404 Chinese CP patients was 28-94(72.47±13.61), which declined by 29.64% compared to the highest total score (103) in the Chinese version of PANQOLI. Score of physical function, role function, emotional function, and self-worth domain was 25.63±4.84, 13.86±2.78, 16.98±6.21 and 16.00±4.65, respectively. Compared to the highest scores (30, 25, 24 and 24), the scores of aforementioned four domains declined by 14.57%, 44.56%, 29.25% and 33.33%, respectively. Univariate analysis showed that sex, age, employment status, smoking, alcohol consumption, and frequency of pancreatitis recurrence were significantly associated with QoL of CP patients. Multiple linear regression analysis indicated that older age (coefficient=-0.127), unemployment status (coefficient=-0.106), smoking (coefficient=-0.176), and high frequency of pancreatitis recurrence (coefficient=-0.123) were independent factors for QoL of CP patients (all P value <0.05). Conclusions:The Chinese version of PANQOLI could be effectively applied to Chinese CP patients. Older age, unemployment, smoking, and pancreatitis attacks were risk factors for QoL of CP patients, indicating that the formulation of personalized intervention measures may help to improve QoL of CP patients.

Objective To explore the beneficial effects and mechanisms of neutrophil elastase (NE) and myeloperoxidase (MPO) on lead-induced hepatic inflammation in mice. Methods The specific pathogen free male C57BL/6 mice were randomly divided into four groups： control group, lead-exposed group, NE inhibitor group, and MPO inhibitor group, with three mice in each group. The mice in lead-exposed group, NE inhibitor group, and MPO inhibitor group were intraperitoneally injected with a dose of 10 mg/kg body mass of lead acetate solution, while the mice of control group received an equal volume of 0.9% saline three times per week for four weeks. In the last seven days, mice in both inhibitor groups were intraperitoneally injected with a dose of 40 mg/kg NE inhibitor sivelestat sodium or MPO inhibitor 4-aminobenzoic acid hydrazide (4-ABAH) once per day. Mouse body weight and liver histopathological changes were observed. The mRNA expression of genes associated with inflammation, such as tumor necrosis factor-α (Tnfa), interleukin-1β (Il1b), interleukin-6 (Il6), and nucleotide-binding oligomerization domain-like receptor protein 3(Nlrp3), apoptosis-associated speck-like protein (Asc) and cysteinyl aspartate specific proteinase (Caspase1) in the mouse liver tissues was detected by real-time quantitative polymerase chain reaction. The protein expression of NLRP3, ASC, and CASPASE-1 was detected using Western blotting. Results The activities of mice in all four groups were generally normal, and there was no significant difference in body weight (P>0.05). The results of hematoxylin-eosin staining showed that the cell size of hepatocytes varied in the lead-exposed mice, with indistinct cell boundaries, indicating early inflammatory responses in liver tissues. After intervention with NE or MPO inhibitors, the early inflammatory responses improved in the liver tissues of the mice in both inhibitor groups, with a better improvement observed in MPO inhibitor group compared with the NE inhibitor group. The mRNA expression of Tnfa, Il1b, Il6, Nlrp3, Asc, and Caspase1, as well as the protein expression of ASC, and CASPASE-1 in the livers of mice in the lead-exposed group was higher compared with those in the control group (all P<0.05). Compared with the lead-exposed group, the relative mRNA expression of Tnfa, Il1b, Il6, Nlrp3 and Asc was decreased in the liver tissues of mice in the NE inhibitor group (all P<0.05), while the relative expression of mRNA of Tnfa, Il1b, Il6, Caspase1 and the protein expression of ASC and CASPASE-1 were decreased in the liver tissues of mice in the MPO inhibitor group (all P<0.05). Conclusion Lead induce hepatic inflammation in mice by activating NLRP3 inflammasome. The inhibition of NE or MPO improve the lead-induced hepatic inflammatory responses in mice by alleviating NLRP3 inflammasome activation.

Methods The targets prediction network of curcumin in treating silicosis was established based on the collection of targets of curcumin and silicosis in multiple databases, cross-targets were submitted to the STRING database, and their connectivity was analyzed by Cytoscape software. Gene ontology (GO) function analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed on the top 20 genes. The molecular docking was performed on the key targets to study the mechanism of action of curcumin in treating silicosis. Results A total of 311 targets related to curcumin, 270 targets related to silicosis, and 74 cross-targets were obtained from the databases. GO function analysis revealed 2 665 related pathways, and KEGG pathway enrichment analysis revealed 188 related pathways. Molecular docking results showed that curcumin had good binding ability with the targets of mitogen-activated protein kinase 3 (MAPK3), interleukin (IL) 6, serine/threonine kinase 1 (AKT1), vascular endothelial growth factor A (VEGFA), signal transducer and activator of transcription 3, albumin, Jun proto-oncogene, tumor necrosis factor (TNF), IL1B, tumor protein p53, C-C motif chemokine ligand 2 and fibronectin 1. Conclusion The therapeutical effects of curcumin on silicosis were implemented through multi-targets and multi-pathways. Curcumin may play a role in the treatment of silicosis by binding to the core targets MAPK3, IL6, AKT1, VEGFA and TNF and regulating the MAPK, IL6, TNF, phosphatidylinositol 3-kinase/protein kinase B and VEGF signaling pathways.
