ObjectiveTo investigate the effects of Huangqi Jianzhongtang （HQJZ） on macrophage polarization and fat consumption in cancer cachexia （CC） mice. MethodsUltra-performance liquid chromatography-quadrupole/electrostatic field Orbitrap high-resolution mass spectrometry （UPLC-Q-Orbitrap HRMS） was used to control the quality of HQJZ. （1） In vitro experiment： HQJZ-containing serum was prepared， and the optimal concentration was determined by cytotoxicity assay. Mouse monocyte-derived macrophages （RAW264.7） were cultured and randomly divided into six groups， including a blank group， a classically activated macrophages （M1） group， an alternatively activated macrophages （M2） group， a HQJZ + blank group， a HQJZ+M1 group， and a HQJZ + M2 group. The relative expression of macrophage marker genes CD86， inducible nitric oxide synthase （iNOS）， CD206， and arginase-1 （Arg1） was detected by real-time quantitative polymerase chain reaction （Real-time PCR ）. （2） In vivo experiment： Thirty-two BALB/c mice were randomly divided into a control group， a model group， a medroxyprogesterone acetate （MPA） group， and a HQJZ group. Except for the control group， the other mice were injected with CT-26 colon cancer cells to establish a CC model. Mice in the MPA and HQJZ groups were given MPA （0.13 g·kg^-1·d^-1） or HQJZ （13.13 g·kg^-1·d^-1） by gavage， respectively， while mice in the control and model groups were given an equal volume of saline by gavage， with interventions continued for 10 d. Real-time PCR was used to detect the expression of macrophage markers （iNOS， Arg1， CD86， CD206） and fat browning-related genes uncoupling protein 1 （UCP1） and peroxisome proliferator-activated receptor γ （PPARγ） in epididymal adipose tissue. Western blot （WB） was used to detect protein expression levels of UCP1 and PPARγ. Micro-computed tomography （micro-CT） was used to measure residual fat volume， and hematoxylin-eosin （HE） staining was used to assess fat browning and calculate pathological scores. ResultsIn vitro， the dominant effective concentration of HQJZ-containing serum was 12.5%. Real-time PCR results showed that， compared with the blank group， Arg1 expression decreased in the HQJZ+blank group （P<0.05）， CD206 showed a downward trend without statistical significance， while iNOS and CD86 expression were significantly increased （P<0.05）. Compared with the M1 group， Arg1 and CD206 expression decreased in the HQJZ+M1 group （P<0.05）. Compared with the M2 group， CD206 expression decreased in the HQJZ+M2 group （P<0.05）， CD86 expression increased significantly （P<0.01）. In vivo， Real-time PCR results showed that， compared with the control group， CD86 and CD206 expression levels were significantly increased in the model group （P<0.01）. Compared with the model group， CD206 expression in the MPA group was significantly decreased （P<0.01）. In the HQJZ group， CD206 was significantly decreased （P<0.01）. WB results showed that， compared with the model group， protein expression of UCP1 and PPARγ was significantly reduced in the HQJZ group （P<0.05， P<0.01）. micro-CT results showed that the total white fat volume in the HQJZ group was greater than that in the model group （P<0.05）. HE staining results showed that pathological scores in the HQJZ group were lower than those in the model group （P<0.05）. ConclusionHQJZ may inhibit white adipose tissue browning by promoting macrophage M1 polarization and suppressing M2 polarization， thereby delaying fat consumption in CC mice.

BackgroundIndividuals with chronic multimorbidity exhibit a high prevalence of sleep disturbances， which impair their physical and psychological well-being and impede chronic disease management. Although sleep quality is closely influencing with psychological functioning， empirical evidence regarding the longitudinal trajectories of sleep quality and their influencing factors in this population remains insufficient. ObjectiveTo investigate the longitudinal trajectories of sleep quality and associated factors among patients with chronic multimorbidity from hospitalization through 6 months post-discharge， aiming to facilitate the early identification of high-risk individuals and the development of personalized sleep interventions. MethodsA total of 228 inpatients with chronic multimorbidity， primarily with cardiovascular and metabolic chronic conditions， were enrolled via random sampling at The Third People's Hospital of Fuyang from January 2023 to September 2024. Baseline assessments were conducted during hospitalization using the general socio-demographic questionnaire， the Sleep Dysfunction Rating Scale （SDRS）， the Ruminative Response Scale （RRS）， and the Hospital Anxiety and Depression Scale （HADS）. Sleep quality was further evaluated using the SDRS at 1-， 3-， and 6-month post-discharge. Latent class growth model was employed to delineate trajectories of sleep quality. Multivariate logistic regression analysis was subsequently performed to identify influencing factors of sleep quality. ResultsA total of 201 patients with chronic diseases were included.Based on four predefined assessment time points （baseline， 1 month， 3 months， 6 months post-discharge）， the latent class growth model identified three distinct trajectories of sleep quality： persistent high sleep disturbance （n=72， 35.82%）， moderate sleep disturbance-progression （n=73， 36.32%）， and low sleep disturbance （n=56， 27.86%）. Multivariate logistic regression analysis revealed that， compared with the low sleep disturbance group， multiple factors increased the odds of membership in the persistent high sleep disturbance group： per capita monthly household income of <3 000 yuan （β=13.131， P<0.01） or 3 000–5 000 yuan （β=5.913， P<0.05）， aged 45–65 years （β=9.536， P<0.05）， presence of 3 （β=7.792， P<0.05） or >3 comorbid chronic conditions （β=6.626， P<0.05）， as well as higher RRS （β=0.334， P<0.01） and HADS score （β=1.628， P<0.01）. Additionally， patients aged 45–65 years （β=2.777， P<0.05）， with 3 （β=3.802， P<0.01） or >3 comorbid chronic conditions （β=2.463， P<0.01）， and with higher RRS （β=0.111， P<0.01） and HDAS scores （β=0.350， P<0.05） also demonstrated significantly increased odds of belonging to the moderate sleep disturbance–progression group. ConclusionThere is significant population heterogeneity in sleep quality trajectories among patients with chronic multimorbidity， with age， per capita household monthly income， number of comorbidities， rumination， and anxiety/depression symptoms being identify as the primary influencing factors.

Objective: To investigate the association between habitual reading/writing postures and the co-occurrence of common health conditions (overweight/obesity, visual impairment, hypertension, and scoliosis) and comorbidities among children and adolescents, in order to provide data support for the joint prevention of common diseases and comorbidities among children and adolescents. Methods: From September 2021 to June 2022, a multi-stage cluster random sampling method was used to select a total of 4 577 children and adolescents from 16 primary and secondary schools in Ningxia: Jinfeng District of Yinchuan City, Shapotou District of Zhongwei City, Yanchi County of Wuzhong City, and Pingluo County of Shizuishan City. A weighted complex sampling design was used to investigate the association of habitual reading and writing postures with common comorbidities in children and adolescents. Results: The prevalence rates of common diseases among children and adolescents in Ningxia were as follows: overweight/obesity was 22.87%, visual impairment was 62.52%, scoliosis was 2.30%, and hypertension was 1.30%. The prevalence of multimorbidity (co-occurrence of ≥2 conditions) among Ningxia children and adolescents was 15.95%. Multivariate unconditional Logistic regression analysis showed that frequent/always collapsing waist and sitting forward with head lowered increased the risk of common comorbidities in children and adolescents ( OR =1.90, P <0.05). Compared with the corresponding reference group, male children and adolescents aged 9 to 12 years and boys had relatively lower risks of overweight/obesity ( OR =0.71, 0.70); the risk of poor vision among children and adolescents aged 9 to 12 years, male, and urban was relatively low ( OR =0.59, 0.60, 0.73)( P < 0.05 ). Children and adolescents who often/always sat leaning to the left or right were at higher risk of poor vision ( OR =1.78); urban children and adolescents had a higher risk of developing scoliosis ( OR =3.71); children and adolescents aged 9 to 12 had a relatively low risk of developing hypertension ( OR =0.09), and children and adolescents who often/always bent their backs and sat forward on their knees had a higher risk of hypertension ( OR =5.03)( P <0.05). Conclusions Ningxia has a high incidence of common diseases and multiple diseases among children and adolescents, frequent or always collapsing waist and sitting forward with head lowered is associated with common comorbidities in children and adolescents in Ningxia. Proper postural measures for reading and writing should be carried out as soon as possible to encourage children and adolescents to develop good reading and writing habits for effectively preventing and controlling the occurrence of common diseases.

Objective To investigate the quality of life status in patients with type 2 diabetes mellitus and its influencing factors,understand their demands for continuous nursing services,analyze the correlation,and provide a reference for formulating and implementing continuous nursing plans for diabetes in the later stage.Methods From May to December 2024,a cross-sectional survey was conducted among 294 patients with type 2 diabetes mellitus in this hospital by using the Self-Rating Anxiety Scale(SAS),the Diabetes Pa-tient-Specific Quality of Life Scale(DSQL),and the Questionnaire on the Need for Continuous Care.Results The SAS score of patients with type 2 diabetes was 45.76±7.45,DSQL score was 54.68±10.99,and the score of continuous care needs was 32.98±5.79.The quality of life of patients with type 2 diabetes mellitus is mainly influenced by factors such as age,family type,educational level,average monthly family in-come,duration of diabetes,blood glucose control,dietary compliance,intensity of physical exercise,and diabet-ic complications.The quality of life of patients with type 2 diabetes mellitus was positively correlated with need for continuous care(P<0.05).Conclusion The quality of life of patients with type 2 diabetes mellitus is influenced by multiple factors and is related to the need for continuous care.Professional continuous care plans can be formulated and implemented based on the needs of patients with type 2 diabetes mellitus.

Objective To systematically analyze the domestic and foreign literature related to interventional nursing care for patients with coronary heart disease in the past 10 years and to make a further understanding of the research status,hot spots and trends in this field so as to provide useful reference for the in-depth research in this field.Methods A computerized retrieval of academic papers concerning the interventional nursing care for patients with coronary heart disease from the databases of CNKI,Wanfang,VIP-CMJD,PubMed and Web of Science was conducted.The retrieval time period was from 1 January,2014 to February 27,2024.NoteExpress and CiteSpace software were used to make visualization analysis for the literature meeting the inclusion and exclusion criteria.Results A total of 4 098 Chinese articles and 381 English articles were enrolled in the analysis.Between 2014 and 2021,the number of domestic and foreign documents was on the rise.The number of foreign publications continued to increase in 2022,thereafter,the number of publications was declined in 2023.The authors with the most published academic papers were WANG Jing(15 articles)and Ayman Elbadawi(7 articles).The research keywords involved a wide range,and the research focus was on the characteristics and perioperative care of coronary heart disease,including quality of life,evidence-based nursing care,complications,myocardial infarction,outcome,mortality,etc.The obvious trend of research was to emphasize the psychological nursing,continuation nursing and rehabilitation nursing for patients with coronary heart disease receiving interventional treatment.Conclusion Although the number of research publications concerning the interventional nursing care for patients with coronary heart disease in the past decade is very large,the authors and institutions lack effective communication and collaboration.In order to improve the overall health,self-care ability and quality of life of patients,the future studies should further strengthen the quality of research,focus on key population,and innovate nursing pattern.

Objective To make an investigation on the current situation of the general surgical nurse's knowledge-attitude-practice for mechanical prevention of venous thromboembolism(VTE),and to analyze its influencing factors,so as to provide scientific basis for improving the mechanical prevention care work of VTE.Methods Using convenience sampling method,from April 2023 to May 2023 a total of 508 general surgery nurses from 28 provinces,municipalities and autonomous regions were selected as the study subjects.A VTE mechanical prevention knowledge-attitude-practice questionnaire designed based on expert consensus was used to conduct the questionnaire survey.Linear regression analysis was used to determine the related factors affecting the knowledge-attitude-practice level of mechanical prevention care work of VTE in general surgery nurses.Results Multiple linear regression analysis showed that the sub-specialty of vascular surgery(P＜0.001)and the frequency of VTE mechanical prevention theory training in hospital(P=0.023)were the factors influencing VTE mechanical prevention knowledge dimension score of general surgery nurses;the sub-specialty of vascular surgery(P=0.033)was the factor influencing attitude dimension score;the sub-specialty of vascular surgery(P＜0.001)and the frequency of VTE mechanical prevention theory training in hospital(P=0.043)were the factors influencing practice dimension score.Conclusion General surgery nurses have a high level of attitude and practice in mechanical prevention of VTE for hospitalized patients,but their knowledge reserve is relatively insufficient.Therefore,the study of VTE-related knowledge and vascular surgery specialty should be strengthened,meanwhile,the frequency of VTE mechanical prevention training at the hospital and department level should be increased.

Objective:To develop a 3D-printed extraocular muscle teaching model and evaluate its teaching effect and learning experience among residents in standardized training.Methods:A total of 24 residents in standardized training who entered the Department of Ophthalmology, Peking Union Medical College Hospital from 2022 to 2024 were included, with 10, 7, and 7 residents in the first, second, and third grades, respectively. A simulated orbit and movable eyeball were constructed based on 3D printing technology. Tractionable elastic silicone bands were arranged on it to simulate healthy extraocular muscles, and non-elastic ropes were used to simulate diseased extraocular muscles. The model was applied in teaching rounds. Before and after the rounds, the residents were tested on basic knowledge (including diagnosis and judgment of surgical indications, with a full score of 40) and core knowledge (including judgment of mainly involved extraocular muscles and surgical design, with a full score of 60). Pearson correlation analysis was used to evaluate the correlation between the residents′ grades and their scores before the rounds, scores after the rounds, and score increments. A questionnaire survey (full score of 100) was conducted to assess their learning experience.Results:Before the teaching rounds, the average basic knowledge score of all residents was (21.0±7.5) and the core knowledge score was (11.3±7.7). These scores were positively correlated with the residents′ grades ( r=0.74, 0.69, all P<0.001) but generally low. After the teaching rounds, the basic knowledge score increased to (31.7±4.6), and the core knowledge score increased significantly to (48.5±3.8). There were no statistically significant differences in these scores among different grades ( P=0.22, P=0.83). The increments of basic knowledge and core knowledge scores decreased with the increase of residents′ grades, with statistically significant correlations ( r=-0.60, -0.65; P=0.002, P=0.001). The average scores of all residents in appearance, convenience, effectiveness, and total score were (18.2±1.1), (26.6±2.2), (40.0±4.0), and (84.8±5.0), respectively. There was no statistically significant correlation between these scores and the residents′ grades ( P=0.24, P=0.84, P=0.25, P=0.58). Suggestions for improving the current teaching model included: increasing the model size for long-distance viewing; enhancing the adhesion between silicone bands (simulating eye muscles) and the simulated eyeball; reducing the friction between the inner sphere and outer shell of the simulated eyeball to improve the model′s maneuverability and flexibility. Conclusions:The 3D-printed extraocular muscle teaching model can help residents of all grades quickly master the key and difficult points in learning restrictive strabismus caused by thyroid-associated ophthalmopathy. In clinical teaching of complex ocular diseases related to systemic diseases, constructing physical teaching models can effectively improve teaching effects and students′ learning experience.

Objective To explore the value of serum Annexin A2(ANXA2),vasohibin-1(VASH1)and caveolin-1(CAV-1)in evaluating pregnancy outcomes in patients with hypertensive disorders of pregnancy(HDP).Methods From June 2020 to April 2023,125 patients with HDP admitted to Qingdao Women's and Children's Hospital were regarded as the research group,according to the pregnancy outcomes,they were separated into a good pregnancy outcome group(n=77)and a poor pregnancy outcome group(n=48).In addition,100 normal pregnant women who underwent pregnancy tests during the same period were regarded as the control group.Enzyme-linked immunosorbent assay(ELISA)was used to detect serum levels of ANXA2,VASH1,and CAV-1.Binary logistic regression was used to analyze the influencing factors of pregnancy outcomes in pregnant women with HDP,and receiver operating characteristic(ROC)curves were drawn to analyze the diagnostic value of serum ANXA2,VASH1,and CAV-1 in the diagnosis of HDP patients pregnancy outcome.Correlation of serum ANXA2,VASH1 and CAV-1 with 24-h urine protein content and blood pressure indices analyzed by Pearson's method.Results Compared with the healthy group,the serum ANXA2(353.19±37.31 μg/L vs 415.32±42.65 μg/L)and CAV-1(6.05±0.64 μg/L vs 6.89±0.73 μg/L)levels in the case group were greatly reduced(t=11.644,9.188),while VASH1(615.48±62.46 ng/L vs 528.63±54.39 ng/L)level was greatly increased(t=10.969),and the differences were statistically significant(all P<0.05).The serum NXA2(322.54±34.24 μg/L vs 372.29±39.23 μg/L)and CAV-1(5.56±0.59 μg/L vs 6.38±0.67 μg/L)levels in poor pregnancy outcomes group were greatly lower than those in good pregnancy outcomes group(t=7.323,6.706),while VASH1(660.29±67.34 ng/L vs 587.56±59.42 ng/L)level was greatly higher(t=6.321),and the differences were statistically significant(all P<0.05).24h urine protein level,VASH1 were risk factors affecting adverse pregnancy outcomes in patients with HDP(P<0.05),serum ANXA2 and CAV-1 were protective factors affecting adverse pregnancy outcomes in patients with HDP,and the differences were statistically significant(P<0.05).ROC curve results showed that the Area under the curve(AUC)of ANXA2,VASH1,CAV-1,and their combination in predicting pregnancy outcomes in HDP patients was 0.809,0.747,0.775 and 0.909,respectively.The AUC predicted by the combination of ANXA2,VASH1,and CAV-1 were greatly better than those predicted by ANXA2,VASH1 and CAV-1 alone(Z=2.720,3.334,3.320,all P＜0.05).ANXA2,VASH1 was negatively correlated with 24h urine protein level and systolic and diastolic blood pressure(r=-0.435～-0.406,all P<0.05),and CAV-1 was positively correlated with 24h urine protein level and systolic and diastolic blood pressure(r=0.428,0.409,0.421,P<0.05).Conclusion The serum ANXA2 and CAV-1 levels in HDP patients decreased,while Ang1 level increased,which has certain auxiliary predictive value for the diagnosis of HDP and the evaluation of pregnancy outcomes.

Pancreatic cancer is a highly lethal malignancy that is usually diagnosed at an advanced stage because of its absence of early symptoms and lack of effective screening tools. Although existing treatments (e.g., surgery, chemotherapy, and radiotherapy) can provide temporary relief, the therapeutic effect of pancreatic cancer remains limited, with major issues related to drug resistance and recurrence. In recent years, immunotherapy and targeted therapy have provided renewed hope to the treatment of pancreatic cancer. The immune microenvironment of pancreatic cancer is complex and strongly immunosuppressive. Immune cells such as tumor-associated macrophages and regulatory T cells can weaken the antitumor function of the immune system by secreting inhibitory factors, thereby enabling the tumor to evade immune surveillance. Meanwhile, immune escape is exacerbated by the infiltration of hypo-immune cells and the role of tumor-associated fibroblasts in the tumor microenvironment of pancreatic cancer. In response to these immune escape mechanisms, combining immunotherapy with targeted therapy has emerged as a focal point of current research. This review compiles the characteristics of the immune microenvironment in pancreatic cancer based on current literature, aiming to provide a basis and insights for related drug development.

Objective: To evaluate the efficacy and safety of the single-use hemoperfusion device (UA230) in treating refractory gout (RG) via plasma perfusion. Methods: Thirty-four RG patients aged 18-65 years were recruited and randomly divided into a control group (febuxostat therapy, n=17) and an experimental group (plasma perfusion combined with febuxostat therapy, n=17). Differences in serum uric acid (SUA) levels and urate-lowering rates between the two groups were analyzed using t-tests. Between-group differences in incidence of adverse reactions were analyzed using chi-square tests. Results: At 7 and 14 days post-treatment, SUA levels in the experimental group were significantly lower than those in the control group, with a higher urate-lowering rate (all P<0.05). However, no statistically significant differences in SUA levels or urate-lowering rate were observed at 28 days post-treatment (all P>0.05). The incidence of adverse reactions showed no significant difference between the two groups (χ =0.15, P>0.05). Conclusion: The single-use hemoperfusion device (UA230), combined with plasma perfusion technology, is a safe and effective treatment for RG. It may serve as a novel therapeutic approach for RG patients in clinical practice.
