Chronic post-surgical pain (CPSP) is a common long-term complication following lung surgery. Its high incidence significantly impacts patients’ quality of life and functional recovery, and imposes a substantial socioeconomic burden. This consensus aims to systematically establish a standardized integrated Chinese and Western medicine diagnostic and treatment framework for chronic post-lung surgery pain (CPLSP). Based on the latest domestic and international evidence-based medical research and multidisciplinary clinical experience, the working group comprehensively elaborates on core issues regarding CPLSP, including its definition, epidemiology, pathogenesis, clinical assessment, Western medical treatment, traditional Chinese medicine (TCM) treatment, and integrated strategies. The consensus emphasizes a patient-centered approach, adhering to the principles of multimodality, individualization, and stepwise management, highlighting the synergistic advantages of integrating Chinese and Western medicine throughout the entire perioperative management cycle encompassing "perioperative anti-inflammation, acute analgesia, and chronic rehabilitation." Through systematic literature retrieval and evidence integration, a total of 9 core recommendations were established to provide scientifically sound and clinically practical guidance.

ObjectiveTo observe the clinical efficacy of the Yiqi Yangyin Huoxue prescription （YYHP） in the treatment of cathartic colon （CC） and its effects on fecal short-chain fatty acids （SCFAs）， and to explore the correlations among CC severity indicators and between these indicators and patient history. MethodsAccording to the inclusion and exclusion criteria， 98 patients meeting the diagnostic criteria of both traditional Chinese and Western medicine for CC with the syndrome of Qi-Yin deficiency complicated by blood stasis were randomly assigned to an observation group and a control group. The observation group received YYHP granules， while the control group received lactulose. Both medications were administered twice daily， one sachet each time， half an hour after breakfast and dinner， with a treatment course of 8 weeks. The primary constipation symptom score， Patient Assessment of Constipation Quality of Life （PAC-QOL） score， and TCM syndrome score were assessed before and after treatment and at the 8^th week after the end of treatment. The overall clinical effective rate， as well as the efficacy attenuation index and degree， were evaluated. Fecal SCFA levels were measured using gas chromatography-mass spectrometry （GC-MS）. Spearman correlation analysis was performed to explore the correlations among CC severity indicators and between these indicators and patient history. ResultsThe overall clinical effective rate in the observation group （95.83%） was higher than that in the control group （78.72%） （P<0.05）. After treatment， the total scores for primary constipation symptoms， PAC-QOL， and TCM syndromes decreased in both groups （P<0.05）， with more significant reductions in the observation group （P<0.05）. The severity of all primary constipation symptoms was alleviated in both groups （P<0.05）. In terms of "excessive straining and difficult defecation"， "anal heaviness， incomplete evacuation， and bloating sensation"， "abdominal distension"， and "defecation frequency"， the observation group showed better efficacy than the control group （P<0.05）. Scores of the four PAC-QOL dimensions and the scores and severity of primary and secondary TCM symptoms were reduced in both groups （P<0.05）， with more significant reductions in the observation group （P<0.05）. After treatment， acetic acid， propionic acid， butyric acid， and total SCFAs in the observation group increased significantly （P<0.05）. The efficacy attenuation index and degree in the observation group were lower than those in the control group （P<0.05）. No severe adverse reactions occurred in either group， and there was no statistically significant difference in the incidence of adverse reactions between the two groups. Positive correlations of varying degrees were observed among the total scores of primary constipation symptoms， PAC-QOL， and TCM syndromes， as well as between these scores and the history of stimulant laxative use， disease duration， and age. ConclusionYYHP can effectively alleviate the primary constipation symptoms in CC patients， improve quality of life， and ameliorate TCM syndromes， with good safety. It also has the advantage of a lower rebound degree after drug withdrawal， and its mechanism may be related to increasing fecal SCFA levels. Long-term abuse of stimulant laxatives may aggravate the severity of CC and prolong the disease course.

Objective To investigate the temporal changes in pathological damage and macrophage polarization in liver and spleen tissues of mice infected with Angiostrongylus cantonensis, and to preliminarily unravel the peripheral immune responses during the early stage of A. cantonensis infection. Methods Forty female BALB/c mice at ages of 6 to 8 weeks were randomly divided into four groups, including the control group and 7-, 14-, and 21-day infection groups, with 10 mice in each group. Each mouse in the infection groups was inoculated with 30 third-stage (L3) larvae of A. cantonensis by oral gavage, and five mice were randomly selected from each infection group on days 7, 14, and 21 post-infection, while mice in the control group were given the same volume of physiological saline and five mice were randomly selected from the control group on the day of oral gavage. Mouse liver and spleen tissues were sampled. The histopathological changes of mouse liver and spleen tissues were observed using hematoxylin and eosin (HE) staining, and the percentage of positive staining area and the co-localization positive rates of the macrophage surface antigens F4/80, CD86, and CD206 were quantified in mouse liver and spleen tissues using immunohistochemical and immunofluorescence staining. In addition, five mice were collected from each infection group on days 7, 14, and 21 post-infection, and five mice were collected from the control group on the day of oral gavage. Mouse liver and spleen tissues were sampled for detection of macrophage markers CD86 and CD206 and macrophage phenotyping using flow cytometry, and the expression of M1 macrophage markers, including inducible nitric oxide synthase (Nos2), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and M2 markers, including arginase 1 (Arg1), mannose receptor C-type 1 (Mrc1) and chitinase-like protein 3 (Chil3) was quantified in mouse liver and spleen tissues using real-time quantitative PCR (RT-qPCR) assay. Results Proliferative lesions of the hepatocyte were observed in mouse liver tissues and the follicular structures of the mouse spleen white pulp were disrupted 21 days post-infection with A. cantonensis. Immunohistochemical staining showed that there were significant differences in the percentages of F4/80, CD86 and CD206 positive staining areas in the liver and spleen tissues among the four groups of mice (F = 242.40, 197.14, 183.19, 157.65, 242.35 and 146.24; all P values < 0.001), and the percentages of positive staining in the liver and spleen tissues of mice in the 14-day infection group [(4.45 ± 0.51)%, (3.74 ± 0.67)%, (8.32 ± 0.72)%, (16.56 ± 1.14)%, (11.62 ± 0.52)%, and (8.29 ± 0.72)%, respectively] and the 21-day infection group [(3.70 ± 0.11)%, (3.22 ± 0.43)%, (11.53 ± 1.03)%, (12.59 ± 1.05)%, (9.02 ± 0.83)%, and (11.67 ± 1.10)%, respectively] were higher than in the control group [(0.35 ± 0.16)%, (0.40 ± 0.02)%, (0.93 ± 0.05)%, (2.78 ± 0.26)%, (2.33 ± 0.20)%, and (1.85 ± 0.20)%, respectively] (all P values < 0.05). Immunofluorescence staining showed significant differences in the positive rates of F4/80 co-localization with CD86 and CD206 in mouse liver and spleen tissues among the four groups (F = 24.42, 25.28, 54.51 and 130.55; all P values < 0.001). Flow cytometry detected significant differences in the proportions of CD86⁺ and CD206⁺ macrophages in mouse liver and spleen tissues among the four groups (F = 67.98, 18.41, 29.77, 172.80; all P values < 0.001), and the proportions of CD206⁺ macrophages in the liver and spleen of the 21-day infection group were significantly higher than those in the control group [(9.25 ± 2.55)% vs (3.83 ± 0.72)%, and (4.22 ± 0.56)% vs (0.47 ± 0.18)%, respectively] (both P values < 0.05). In addition, RT-qPCR assay quantified significant differences in the relative mRNA expression of M1 macrophage markers (IL-1β, TNF-α and Nos2) and M2 macrophage markers (Arg1, Chil3 and Mrc1) in mouse liver and spleen tissues among the four groups (F = 41.30, 31.82, 199.33, 19.96, 62.01, 119.76, 23.67, 95.90, 72.27, 82.59, 123.41 and 29.75; all P values < 0.05). Conclusions A. cantonensis infection may cause progressive pathological damage in mouse liver and spleen tissues, accompanied by dynamic temporal changes in macrophage polarization. M1 macrophage polarization predominates at the early stage of A. cantonensis infection and shifts towards M2 polarization at the later stages, suggesting that M2 polarization may participate in immune regulation at late stages of A. cantonensis infection by suppressing excessive inflammatory responses and promoting tissue repair.

Objective: To explore the related factors of college students social network addiction based on problem behavior theory, so as to provide a basis for improving social networking addiction in this population. Methods: From May to June 2023, a method combining convenient sampling and cluster random sampling was used to select 1 768 college students from five universities in Shanghai for a questionnaire survey on social networking addiction, self esteem, loneliness, depressive symptoms, social support, interpersonal needs, sense of distress and frustration; at the same time, the physical exercise, smoking and drinking of college students were investigated. Multivariate Logistic regression analysis was applied to explore the association between the three systems of the problem behavior theory (personality, behavior, and social environment) and social networking addiction among college students. Results: The score on the Social Network Addiction Tendency Scale was (21.08±6.29) among college students, and the detection rate of social networking addiction was 66.29%. After adjusting for gender, family economic status, parental divorce status, and whether being an only child, multivariate Logistic regression analysis showed that in the personality system, higher loneliness ( OR =1.66) and higher depressive symptoms ( OR =2.18) were associated with increased risk of social networking addiction among college students; in the behavior system, alcohol consumption ( OR =1.42) was associated with higher risk of soical networking addiction compared to non drinkers; and in the social environment system, low social support ( OR =1.43) was associated with increased risk of social networking addiction (all P <0.05). Conclusions The rate of social networking addiction among college students is relatively high, and the systems of personality, behavior, and social environment are all related to social network addiction. Providing social support, cultivating healthy lifestyle habits, and increasing interpersonal interactions may help reduce excessive dependence on social networking among college students.

Objective To evaluate the short-term efficacy of the VISULYZE software generated nomogram in assis-ting small incision lenticule extraction(SMILE)for the correction of myopia and astigmatism.Methods Non-randomized controlled trial.Patients who underwent SMILE surgery with the original nomogram,assisted by the same surgeon at the Laser Myopia Treatment Center of Xi'an NO.1 Hospital between February 2023 and January 2024,were included.A total of 52 patients(102 eyes)of myopic astigmatism with 3-month postoperative follow-up were collected.VISULYZE software was then used to generate a new nomogram.Subsequently,a total of 40 patients(70 eyes)with myopic with-the-rule astigmatism and a preoperative cylinder of ≤2.00 D,who underwent SMILE assisted by the new nomogram at the same center between August and November 2024,were enrolled.Among them,50 eyes had a target refraction of plano and were assigned to the experimental group.In addition,from the database of patients who underwent SMILE assisted by the origi-nal nomogram,42 patients(70 eyes)with myopic with-the-rule astigmatism and a cylinder of ≤2.00 D were screened,of which 51 eyes had a target refraction of plano,and these were assigned to the control group.The postoperative visual and refractive outcomes of both groups were compared at 3 months.Astigmatism results were analyzed using Alpins vector analysis.Results At 3 months postoperatively,among eyes with a target refraction of plano,50 eyes(98.0％)in the control group and all 50 eyes(100.0％)in the experimental group achieved an uncorrected distance visual acuity(UDVA)of ≥ 20/20.No eye in either group experienced a loss of more than one line in corrected distance visual acuity(CDVA)compared with the preoperative level.At 3 months postoperatively,63 eyes(90.0％)in the control group and 66 eyes(94.3％)in the experimental group had a spherical equivalent(SE)within-0.50 to 0.50 D.The postoperative cylinder was significantly lower in the experimental group than in the control group(P＜0.05).Vector analysis revealed that the ex-perimental group had smaller values for the difference vector,index of success,and absolute angle of error than the control group,with all differences being statistically significant(all P＜0.05).At 3 months postoperatively,43 eyes(61.4％)in the control group and 57 eyes(81.4％)in the experimental group had an angle of error within-5° to 5°.Conclusion The use of the VISULYZE software generated nomogram can optimize SMILE surgery design,offering good efficacy,safety,and predictability,and improving the precision of SMILE surgery for correcting myopia and astigmatism.

Objective To develop a systematic and scientific assessment-adaptation-evaluation framework for wheelchair cushions.Methods A mixed-methods approach integrating literature review,qualitative interviews and Delphi expert consultation was employed.First,27 relevant studies were identified through systematic literature searches,comprehensively synthesizing wheelchair cushion types,performance indicators,key assessment/adaptation elements and evalua-tion methods.Second,semi-structured interviews were conducted with 24 wheelchair users and six assistive tech-nology specialists.Interview transcripts were analyzed using Colaizzi's phenomenological analysis to extract themes and deeply explore user needs and practitioner experiences.Based on the literature and interview find-ings,the research team developed a preliminary protocol comprising an assessment form,an adaptation process table and an effectiveness evaluation form.Finally,20 multidisciplinary experts participated in a two-round Del-phi consultation.Experts rated the importance of items using a 5-point Likert scale.Consensus was analyzed us-ing Kendall's W coefficient and the coefficient of variation(CV),supplemented by mean importance scores and full-score frequency to refine the protocol.Results The consultation demonstrated excellent expert engagement(100%response rate)and strong authority(Cr=0.90).The finalized protocol comprised of an assessment form(four primary domains/21 secondary items),an ad-aptation protocol(two primary domains/eight secondary items)and an evaluation form(two primary domains/15 secondary items).Statistical analysis revealed Kendall's W=0.20(P<0.05),mean importance scores of(4.48±0.72),CV=(0.15±0.05),and full-score frequency of(60.80±16.39)%,indicating acceptable consensus.Conclusion The assessment-adaptation-evaluation method for wheelchair cushions constructed in this study is scientific,comprehensive and operable,and can provide a standardized tool for clinical personalized adaptation.Future studies should enhance the applicability of the method in diverse clinical settings.

BACKGROUND:Wolff's law points out that the lack of mechanical stress in the body will lead to the degradation of the microstructure of bone tissue,mass loss,and metabolic disorders,and eventually lead to osteoporosis,which suggests that mechanical stress plays an important role in the growth,reconstruction,and formation of bone tissue.At present,the relevant studies concerning mechanical stress on osteoblasts mainly focus on fluid shear force,but it is difficult to intervene in vivo.Meanwhile,some studies have found that compressive stress can also play a similar role in fluid shear force to a certain extent.Exploring the mode of action and influence of compressive stress on cells in vitro experiments can enrich the interaction relationship between mechanical stress and cells.It helps provide a theoretical basis for studies of metabolic bone diseases,including osteoporosis,and other diseases.OBJECTIVE:To review in vitro experiments,the application of compressive stress to cells,different biological behaviors caused by cells,the possible signaling pathways,and possible future applications.METHODS:We searched PubMed,Web of Science,CNKI,and WanFang databases from January 2000 to March 2024 to include all articles related to compressive stress on cells,including basic research and microscopic mechanism studies,using search terms"compressive stress,mechanical stress,hydrostatic pressure,cell"in Chinese and English.Finally,the 63 included articles were reviewed.RESULTS AND CONCLUSION:(1)There are various ways to apply compressive stress,and different experimental equipment has different ways of pressurizing cells,so it is necessary to further standardize the experimental equipment,standardize the pressurization unit,reduce the confounding factors,and make the reference and comparability between different experimental groups.(2)Compressive stress can cause changes in cell proliferation,differentiation,autophagy,apoptosis,migration,etc.,and the effect of compressive stress is time-or dose-dependent in most cases.(3)At present,most in vitro experimental studies have shown that compressive stress may mainly act on osteoblasts through MAPK signaling pathway and Wnt/β-catenin signaling pathway,causing osteoblasts to produce different responses.(4)The effect of compressive stress on different cells is not the same,and its possible biological effects need to be studied.(5)Further research on compressive stress is helpful to provide a theoretical basis for treatment in orthopedics,stomatology,tumors and other fields,and gentle disinfection using hydrostatic pressure is a promising disinfection method.

Objective To analyze the correlation between lesion volume,lesion mass,and maximum lesion diameter in the assessment of advanced hepatocarcinoma with lung metastasis,and to evaluate the application value of total volume response and total mass response of lung metastatic lesions in efficacy assessment.Methods A retrospective analysis was conducted on the CT imaging data of 20 patients clinically confirmed with hepatocarcinoma and lung metastases,followed by subsequent follow-up to monitor their survival outcomes.Volume measurement software was used to measure the volume of lesions before and after treatment.We recored lesion diameter,volume measurements and CT values,calculated the mass of the lesions.The correlation between lesion volume,mass and diameter was analyzed,as well as the correlation between the change rates of volume,mass and lesion diameter.Additionally,the total volume and total mass of all lesions were calculated.The correlation between the change rates of total volume/total mass and the change rate of pulmonary lesion diameter under the RECIST 1.1 criteria,as well as the correlation with changes in patients'tumor markers,were analyzed.Furthermore,the overall volume response and overall mass response of lesions were evaluated based on changes in total volume and total mass,and their consistencies with the RECIST 1.1 criteria for efficacy evaluation were analyzed.Finally,univariate Cox regression analysis was performed to explore the association between these variables and patient survival outcomes.Results There was strong correlation between lesion volume,mass and tumor diameter(r=0.771,0.775),between the rate of change in mass and the rate of change in lesion diameter(r=0.846),and between the rates of change in total volume/total mass and the rate of change in pulmonary lesion diameter under the RECIST 1.1 criteria(r=0.800,0.896).The correlation between the rates of change in total volume/total mass and patients'tumor markers was not statistically significant.There was moderate correlation between the rate of change in volume and the rate of change in lesion diameter(r=0.692).The evaluation results of total volume response and total mass response for pulmonary lesions in advanced hepatocarcinoma with lung metastasis were generally consistent with the RECIST 1.1 criteria(Kappa=0.486,0.426).Univariate Cox regression analysis revealed that total lesion volume(P=0.047)and total lesion mass(P=0.049)were independent prognostic factors for survival outcomes.Conclusion Lesion volume,mass,and diameter,as well as their respective change rates,were found to be interrelated.Furthermore,total lesion volume and total lesion mass were identified as independent prognostic factors for survival outcomes.The total volume response and total mass response are promising evaluation methods in evaluating the efficacy of lung metastasis of hepatocarcinoma,which are different from the RECIST 1.1 evaluation criteria.
