This study aims to evaluate the immediate efficacy of contralateral acupuncture (CAT) on SI3 combined with active exercise in treating ALS.Methods and Analysis: This study is a randomized controlled trial which will recruit 118 eligible participants aged 18 to 55 years with ALS at the Second Affiliated Hospital of Yunnan University of Chinese Medicine between March 2024 and December 2026. Participants will be randomly assigned to the acupuncture group or the sham-acupuncture group in a 1:1 ratio. The acupuncture group will receive a 10-minute acupuncture treatment combined with active exercise, while the sham-acupuncture group will receive a 10-minute sham acupuncture treatment combined with active exercise. Randomization will use a computer-generated sequence with allocation concealed in opaque envelopes. The primary outcome will be the pain visual analogue scale (VAS) scores after 10 minutes of treatment. Secondary outcomes will include the pain VAS scores at other time points (2, 4, 6, and 8 minutes post-treatment), the lumbar range of motion (ROM) scores at various time points, blinded assessment, the treatment effect expectancy scale, and the rescue analgesia rate. The analysis will follow the intention-to-treat principle. The primary outcome will be analyzed using ANCOVA, and secondary outcomes with repeated measures ANOVA. The rescue analgesia rate will be assessed using either the χ2 test or Fisher’s exact test.Discussion: This study is the first randomized controlled trial to assess the immediate efficacy of CAT in combination with active exercise for ALS. This study will provide a simple, rapid, and effective treatment for the clinical management of ALS.Keywords: acute lumbar sprain, immediate efficacy, contralateral acupuncture, active exercise, randomized controlled trial

Thus, we aimed to evaluate the effects of acupuncture for treating AECOPD.Methods: Eight databases were searched from database inception to July 30, 2023. All RCTs compared acupuncture plus conventional western medicine with conventional western medicine alone were included. Outcomes were quality of life, lung function, blood oxygen condition, exercise capacity, daily symptoms, duration of hospitalization, and adverse events. The statistical analyses were conducted using Stata 17.0, and methodological quality was measured by the Cochrane bias risk assessment tool. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to assess the quality of evidence.Results: Twelve studies including 915 patients were included. Compared with conventional western medicine alone, acupuncture combined with conventional western therapy significantly improved quality of life (CAT: MD: − 3.25; 95% CI: − 3.73 to − 2.78, P< 0.001) and arterial blood gas (PaCO2: MD: − 1.85; 95% CI: − 2.74 to − 0.95, P< 0.001; PaO2: MD: 5.15; 95% CI: 1.22 to 9.07, P = 0.01). And for lung function, statistical benefits were found in FEV1/FVC (MD: 4.66; 95% CI: 2.21 to 7.12, P< 0.001), but no difference was seen for FEV1% (MD: 1.83; 95% CI: − 0.17 to 3.83, P = 0.073). There was no significant improvement in exercise capacity (6MWD: MD: 96.69; 95% CI: − 0.60 to 193.98, P = 0.051), hospitalization duration (MD: − 5.70; 95% CI: − 11.97 to 0.58, P = 0.075), and dyspnea (mMRC: MD: − 0.19; 95% CI: − 0.61 to 0.63, P = 0.376) between two groups. Overall bias for CAT and mMRC was in “high” risk, FEV1%, FEV1/FVC, PaCO2, and PaO2 was in “some concern” and 1 RCT assessing hospitalization duration was in “low” risk. And the overall assessments were either moderate, low or very low certainty. Seven trials performed safety assessment of acupuncture, and no serious adverse events were reported.Conclusion: Acupuncture might have auxiliary effects on AECOPD. However, the quality of the evidence is limited, and more high-quality RCTs are needed to be performed in the future.Keywords: acute exacerbation of chronic obstructive pulmonary disease, acupuncture, systematic review, meta-analysis

Patients included 20 men and 22 women, with an average age of 55.97± 14.92 years. The average follow-up period was 13.19 months. The demographic data, operation time (min), and complications were recorded and analyzed. The visual analogue scale (VAS), Oswestry Disability Index (ODI) scores were used to evaluate the surgical outcomes. Three-dimensional CT scans and MRI were conducted to evaluate the radiographic improvement.Results: A total of 26 patients were diagnosed with lumbar disc herniation and 16 with lumbar spinal stenosis. All 42 patients underwent UME surgery and achieved satisfactory outcomes. The operation time was 154.46± 46.09 min. The average follow-up time was 13.19± 1.33 months. The preoperative back pain (VAS-Back) and the last follow-up VAS-Back were 3.84± 1.00 and 0.70± 0.46, respectively (P < 0.05). The preoperative leg pain (VAS-Leg) and the last follow-up VAS-Leg were 6.46± 1.08 and 1.03± 0.64, respectively (P < 0.05). Significant differences existed between preoperative ODI scores (58.70± 11.22%) and the last follow-up ODI scores (9.24± 3.04%; P< 0.05). All patients achieved significant pain relief and functional improvement after the surgery. No severe complications occurred, except for two cases of postoperative dysesthesia and one case suffered from vertebral compression fractures induced by a postoperative accidental injury. Symptoms of numbness disappeared within one week with treatment using dexamethasone and neurotrophic drugs. The vertebral fracture case recovered with percutaneous kyphoplasty treatment.Conclusion: This study suggests that UME is a promising treatment strategy for high-migrated disc herniation and bilateral spinal stenosis.Keywords: unilateral bi/multi-portal endoscopy, lumbar degenerative diseases, high-migrated disc herniation, bilateral spinal stenosis, ligamentum flavum, spinal endoscope

However, the underlying molecular mechanism of myocardial remodeling after MI remains obscure. This study aimed to identify the hub differential expression genes (DEGs) of myocardial remodeling after MI and determine the distribution of immune cells infiltrating the pathology.Methods: We downloaded GSE132143, GSE151834, and GSE176092 data from the GEO database. The GSE132143 dataset was used to identify DEGs, perform functional annotation, and screen hub genes based on protein-protein interaction (PPI) analysis. The GSE151834 dataset was used to validate the expression of hub genes. CIBERSORTx analysis was performed to explore the immune microenvironment in myocardial remodeling after MI. After conducting a literature review, we selected P3H3 to confirm the expression by utilizing immunohistochemistry and qRT-PCR. Finally, the snRNA-seq data in dataset GSE176092 was used for clarifying the expression of these hub genes in various cell clusters.Results: We found 975 DEGs in myocardial remodeling after MI. Four hub genes (P3H3, COL15A1, COL16A1, COL27A1) were identified and were verified in the GSE151834 dataset. According to immune infiltration analysis, CD4+ naive T cells, regulatory T cells, monocytes, M2 macrophages, and neutrophils were involved in the pathological process of myocardial remodeling after MI. Additionally, in vitro experiments verified that P3h3 expression was significantly elevated in myocardial remodeling after MI. The snRNA-seq data analyzed that P3h3, Col15a1, Col16a1, and Col27a1 were highly expressed in fibroblasts of post-MI.Conclusion: This study identified four hub genes P3H3, COL15A1, COL16A1, and COL27A1, particularly P3H3, as potential targets for targeted therapy in MI patients.Keywords: myocardial infarction, myocardial remodeling, hub genes, immune infiltration, bioinformatic analysis

MiRNA has important prospects in the treatment of diabetic foot refractory wound ulcers. Previous studies have reported that miR-185-5p reduces hepatic glycogen production and fasting blood glucose levels. We herein hypothesized that miR-185-5p might play an important role in the field of diabetic foot wounds.Materials and Methods: MiR-185-5p in skin tissue samples from patients with diabetic ulcers and diabetic rats were measured using quantitative real-time PCR (qRT-PCR). The streptozotocin-induced diabetes rat model (male Sprague-Dawley rats) for diabetic wound healing was conducted. The therapeutic potential was observed by subcutaneous injection of miR-185-5p mimic into diabetic rat wounds. The anti-inflammation roles of miR-185-5p on human dermal fibroblast cells were analyzed.Results: We found that miR-185-5p is significantly downregulated in diabetic skin (people with DFU and diabetic rats) compared to controls. Further, in vitro upregulation of miR-185-5p decreased the inflammatory factors (IL-6, TNF-α) and intercellular adhesion molecule 1 (ICAM-1) of human skin fibroblasts under advanced glycation end products (AGEs). Meanwhile, the increase of miR-185-5p promoted cell migration. Our results also confirmed that the topical increase of miR-185-5p decreases diabetic wound p-nuclear factor-κB (p-NF-κB), ICAM-1, IL-6, TNF-α, and CD68 expression in diabetic wounds. MiR-185-5p overexpression boosted re-epithelization and expedited wound closure of diabetic rats.Conclusion: MiR-185-5p accelerated wound healing of diabetic rats, reepithelization, and inhibited the inflammation of diabetic wounds in the healing process, a potentially new and valid treatment for refractory diabetic foot ulcers.Keywords: diabetes, miRNA, wound healing, inflammation

Based on the positive effect of both intergroup contact and ingroup identification on mental health and well-being, this article proposes and tests a new model of individual loneliness reduction through intergroup contact by promoting common ingroup identity.Methods: A total of 263 majority ethnic members and 275 minority ethnic members from China participated in the survey. Intergroup contact, common ingroup identity and loneliness were measured at three time-points (T1-T3) over an 8-month period. Longitudinal mediation analysis and parallel process Latent Growth Curve Model for mediation are used for the examination of the indirect effect of common ingroup identity.Results: Longitudinal mediation analysis showed that intergroup contact quality at T1 positively predicted common ingroup identity at T2, and common ingroup identity at T2 alleviated loneliness at T3. Intergroup contact quality at T1 was indirectly linked to loneliness at T3 via common ingroup identity at T2. The parallel process latent growth curve model for mediation confirmed the robustness of the indirect effect of common ingroup identity. In addition, the growth rate of the quality of intergroup contact increased the growth rate of common ingroup identity, but reduced the growth rate of loneliness.Conclusion: The current study revealed the protectiveness of intergroup contact and common ingroup identity on loneliness, viz., intergroup contact reduces individual loneliness by promoting common ingroup identity, the implication being that intergroup contact and common ingroup identity should be taken into account in intervening process of loneliness prevention so that an individual’s physical and mental health could be better safeguarded.Keywords: intergroup contact, common ingroup identity, loneliness, group-based intervention

Our previous study has demonstrated the effectiveness of Shu-Mu ACE in the treatment of abdominal obesity (AO). However, the neurological mechanism of Shu-Mu ACE for weight loss has not yet been elucidated. The mechanism of the combination of the Shu and Mu acupoints may be related to the central integrative effects of the brain. This paper aims to explore the potential neural mechanisms of Shu-Mu ACE in female patients with AO.Methods and Analysis: A total of 100 eligible female AO patients and 20 healthy female subjects will be recruited for this study. 100 AO patients will be randomly allocated to five groups: Shu-Mu ACE (Group A), Shu ACE (Group B), Mu ACE (Group C), sham ACE (Group D), and waiting-list (Group E). Treatment will be administrated once every two weeks for 12 weeks. The body mass index (BMI), waist circumference (WC), Visual Analog Scales (VAS) of appetite, Self-Rating Anxiety Scale (SAS), and Self-Rating Depression Scale (SDS) will be utilized to evaluate the clinical efficacy. Outcomes will be assessed at baseline and at each time point of treatment. Multimodal MRI will be performed at baseline and after 12-week treatment and the results will be used to investigate the neural mechanisms of ACE for obesity. Neurological changes and clinical data will be analysed for correlation.Discussions: This study hypothesized that Shu-Mu ACE therapy has a synergistic effect and may treat AO by modulating the neuropathological alterations in the brain. Our findings will demonstrate the neurological mechanism of AO treated by “Shu-Mu” Acupoint Catgut Embedding and compatibility relation.Trial Registration: This trial is registered at the Chinese Clinical Trial Registration Center (No. ChiCTR2100048920).Keywords: acupoint catgut embedding, female, abdominal obesity, Shu-Mu acupoints, compatibility relation, study protocol, neurological mechanism

Thermodynamic behavior has been extensively used to evaluate the stability of materials and predict the direction of the chemical reaction at different pH values, temperatures, potentials, and ion concentrations. Although researching efforts on Sn species in an aqueous solution system (Sn/H2O) of acid, alkali, and salt have been reported, scattered data leads to the inefficiency of a thermodynamic method in the practical application. This article provides a brief review on the potentialpH diagram for Sn/H2O system, which reflects the thermodynamic behavior of Sn species in an aqueous solution and extracts thermodynamic data for the practical application of Sn species. Firstly, the relationship of the thermodynamic behavior, potential-pH diagram, and equilibrium relations of Sn species for Sn/H2O system was overviewed. Additionally, the potential-pH diagram of Sn/H2O system at different temperatures (298 K, 373 K, and 550 K), dissolved Sn activities (1, 10−1, 10−3, and 10−6), and the potential-pH diagram of the Sn species in a chloridion aqueous solution (Sn/H2O-Cl) was summarized. Finally, the application prospect of the potential-pH diagram for Sn/H2O system was investigated in the intelligent simulation of Sn metallurgy and the practical application of Sn materials.

The article of acupoint catgut embedding (ACE) on AO has already been accepted to be published and showed significant effect. However, whether ACE is effective for abdominally obese female with strong appetite is still unclear.Methods: This is a mixed analysis of a multicenter, double-blind, randomized controlled trial.Which was conducted in China between July 2018 and March 2020 (n = 101), while with the supplementary samples (n = 22) between April 2020 and June 2022. According to the appetite and intervention methods, 123 abdominally obese female were divided into ACE group with strong appetite (n = 27) and moderate appetite (n = 31), control (non-acupoint catgut embedding) group with strong appetite (n = 37) and moderate appetite (n = 28). Four subgroups were given a 12-week actual intervention period and a 4-week follow-up. Waist circumference (WC), appetite, body weight and BMI were applied and assessed at baseline and after 6, 12 and 16 weeks.Results: In this study, the mean onset age of abdominal obesity in females was 25.27 (8.19) years old. The longer duration of AO, the lower the appetite in females (p< 0.05). At 12 and 16 weeks, ACE group with strong appetite showed significant decrease in WC and appetite than control group with strong appetite (p< 0.01). However, ACE group with moderate appetite showed no significant decrease than control group with moderate appetite in WC, appetite, body weight and BMI (p> 0.05). At 12 and 16 weeks, there was no significant difference in appetite between the ACE groups (strong and moderate appetite)(p> 0.05), while there was still a difference between the control groups (p< 0.05).Conclusion: Younger abdominally obese female had a stronger appetite. ACE own the remarkable therapeutic effects for younger abdominally obese female and showed the perfect effect on appetite-reduction.Keywords: acupoint catgut embedding, abdominal obesity, obese female, appetite, waist circumference

Improvement of postoperative life quality, proof of clinical efficacy and evidence-based evaluation are the current research trends and frontiers.Keywords: acupuncture analgesia, pain after surgery, bibliometric analysis, CiteSpace

Purpose: To evaluate the biomechanical profile of subcortical backup fixation (subcortical button [SB]) in anterior cruciate ligament (ACL) reconstruction as compared with a bicortical post and washer (BP) and suture anchor (SA) when used with interference screw (IS) primary fixation and to evaluate the utility of backup fixation for tibial fixation with extramedullary cortical button primary fixation. Methods: Fifty composite tibias with polyester webbing–simulated graft were used to test constructs across 10 methods. Specimens were separated into the following groups (n = 5): 9-mm IS only, BP (with and without graft and IS), SB (with and without graft and IS), SA (with and without graft and IS), extramedullary suture button (with and without graft and IS), and extramedullary suture button with BP as backup fixation. Specimens were tested under cyclic loading and then loaded to failure. Maximal load at failure, displacement, and stiffness were compared. Results: Without a graft, the SB and BP had similar maximal loads (802.46 ± 185.18 N vs 785.67 ± 100.96 N, P = .560), and both were stronger than the SA (368.13 ± 77.26 N, P < .001). With graft and an IS, there was no significant difference in maximal load between the BP (1,461.27 ± 173.75 N), SB (1,362.46 ± 80.47 N), and SA (1,334.52 ± 195.80 N). All backup fixation groups were stronger than the control group with IS fixation only (932.91 ± 99.86 N, P < .001). There was no significant difference in outcome measures between the extramedullary suture button groups with and without the BP (failure loads of 721.39 ± 103.32 N and 718.15 ± 108.61 N, respectively). Conclusions: Subcortical backup fixation in ACL reconstruction has similar biomechanical properties to current methods and is a viable backup fixation alternative. Backup fixation methods work synergistically with IS primary fixation to strengthen the construct. There is no advantage to adding backup fixation to extramedullary button (all-inside) primary fixation when all suture strands are secured to the extramedullary button. Clinical Relevance: This study provides evidence that subcortical backup fixation is a viable alternative for surgeons during ACL reconstruction.

However, the pathogenesis of PE is unclear and reliable early diagnostic methods are still lacking. The purpose of this review is to summarize potential metabolic biomarkers and pathways of PE, which might facilitate risk prediction and clinical diagnosis, and obtain a better understanding of specific metabolic mechanisms of PE.Methods: This review included human metabolomics studies related to PE in the PubMed, Google Scholar, and Web of Science databases from January 2000 to November 2021. The reported metabolic biomarkers were systematically examined and compared. Pathway analysis was conducted through the online software MetaboAnalyst 5.0.Results: Forty-one human studies were included in this systematic review. Several metabolites, such as creatinine, glycine, L-isoleucine, and glucose and biomarkers with consistent trends (decanoylcarnitine, 3-hydroxyisovaleric acid, and octenoylcarnitine), were frequently reported. In addition, eight amino acid metabolism-related, three carbohydrate metabolism-related, one translation-related and one lipid metabolism-related pathways were identified. These biomarkers and pathways, closely related to renal dysfunction, insulin resistance, lipid metabolism disorder, activated inflammation, and impaired nitric oxide production, were very likely to contribute to the progression of PE.Conclusion: This study summarized several metabolites and metabolic pathways, which may be associated with PE. These high-frequency differential metabolites are promising to be biomarkers of PE for early diagnosis, and the prominent metabolic pathway may provide new insights for the understanding of the pathogenesis of PE.Keywords: gestational hypertension, metabolite, biomarker, prediction

Although intergroup relationships have been studied extensively, the individual roles of quantity and quality of contact in relationships with cognition, emotion, and intention of behavior toward other ethnic minority groups are not fully understood. This study explores the situation via network analysis among Zhuang and Yao ethnic minorities in Southwest China.Methods: We investigated the quantity and quality of intergroup contact and cognition, emotion, and intention of behavior among a sample of 543 Zhuang and 490 Yao ethnic group members. Data were analyzed using the R-package. Network structures were analyzed via the Qgraph package, and the accuracy and stability of the network were measured via the Bootnet package; communities were detected via the Igraph package; bridge analyses were conducted via the Networktools package; and the network difference was compared via the Network Comparison Test package.Results: The results indicated perceived intimacy is the central node. Quantity of contact constructed a community with “perceived connection,” “sense of community,” “knowledge about out-group,” and “perceived similarity.” Meanwhile, quality of contact constructed a community with “intergroup attitude” and a “feeling thermometer.” The remainder of the nodes constructed two additional communities. The network global connectivity and structure between the two ethnic groups were highly similar.Conclusion: The study examined the quantity and quality of intergroup contact via network analysis for two ethnic minority groups. It was shown that the two groups’ global network structures of intergroup contact and their effects are highly similar. Specifically, quantity and quality of contact produce different effects on intergroup relations. Quantity of contact has proximal effects, including instant cognitive and emotional response without depth cognition, while quality of contact has proximal effects that may change deep-seated cognition and subsequently improve intergroup relations.Keywords: quantity, quality, community analysis, network global connectivity, ethnic minorities, intergroup relationships

However, there is no bibliometric analysis of functional magnetic resonance imaging (fMRI) studies on acupuncture analgesia. This study visualized the current status, hot spots and frontiers of fMRI studies on acupuncture analgesia in the past 20 years to provide a theoretical basis for its clinical application.Methods: All publications were obtained from Science Citation Index-Expanded (SCI-E) of Web of Science (WOS). We used CiteSpace to analyze publications, journals, cited journals, authors, cited authors, institutions, countries, references, and keywords. We also analyzed collaborative network maps and co-occurrence network maps.Results: We retrieved a total of 797 articles. Regarding the volume of publications, the total number of annual publications showed a fluctuating but overall increasing trend. Evidence-based Complementary and Alternative Medicine (21 articles) was the most productive journal, and Pain (225 articles) was the most cited journal. The most productive author was Qin W (16 articles), and the most co-cited author was Hui KKS (111). The most prolific institution and country were Massachusetts General Hospital (34 articles) and USA (212 articles). “Pain” was the top-ranked for keyword frequency and centrality. “Functional connectivity” was the frontier hotspot for 2018– 2021.Conclusion: First, fMRI researches on acupuncture analgesia involved several countries (regions) and institutions, mainly located in the USA, China and Korea, and most of them were universities. In addition, the USA was a major contributor in this field. Second, in terms of disciplinary distribution, the literatures were mainly from clinical neurology, neuroscience, and radiology nuclear medicine medical imaging. Third, the keyword co-occurrence analysis showed that the hot keywords included pain, fMRI, and lower back pain. Fourth, through keyword clustering analysis, the hot disease was found to be lower back pain, and the hot contents were acupuncture specificity and frequency specificity. Fifth, a timeline analysis of the references identified that chronic low back pain and specificity will remain a hot topic for future research.Keywords: acupuncture analgesia, functional magnetic resonance imaging, CiteSpace, bibliometric analysis

We aim to comprehensively delineate oligodendrocyte heterogeneity in young and aged mice and to reveal the underlying mechanism for myelin loss during aging.Methods: Diffusion tensor imaging and immunofluorescent staining were performed to verify the demyelination in the aged brains of both rodents and human. Further, the single-cell RNA sequencing data of all brain cells from young and aged mice were deeply analyzed to identify the subsets of oligodendrocyte lineage cells. Cell-to-cell interaction analysis was performed to detect the mechanism of observed changes in oligodendrocyte generation.Results: Oligodendrocytes were observed to up-regulate several senescence associated genes in aged brain. Four clusters of oligodendrocyte precursor cells (OPCs) were identified in both young and aged brains. The number of those OPCs in basal state was significantly increased, while the OPCs in the procedure of differentiation were immensely decreased in aged brain. Furthermore, it was identified that activated microglia in the aged brain released inflammatory factors to suppress OPC differentiation. Stat1 might be a potential target to transform senescent microglia into tissue repair type to promote oligodendrocyte generation.Conclusion: These results provided a perspective on how age activated microglia could impede remyelination and might give a new therapeutic target for age-related remyelinating diseases.Keywords: remyelination, oligodendrocyte precursor cells, microglia, oligodendrocytes, single cell RNA sequencing

OAB scores and QOL scores were collected before and 6 months after DBS treatment (The target of DBS is STN). We evaluated the related factors affecting QOL score and also the changes in QOL score after DBS treatment.Results: The mean age of 20 patients was 60.6± 6.3 years, with 65% of patients identified with OAB in urodynamic studies. The mean OAB total score and QOL score at baseline were 7.3± 3.7 and 5.0± 1.1, respectively. Four items in the OAB score were found to be independent factors and they influenced the baseline QOL scores. Six months after DBS treatment, the OAB total score and the QOL score were significantly decreased (3.7± 3.2 (p = 0.002) and 3.4± 1.4 (p < 0.001), respectively). Improvements in OAB item 2 (nocturia) and item 3 (urgency) scores were found to be independent factors, which had an influence on the improvement in QOL scores from multivariate analysis. Improvement of OAB item 2 (nocturia) exhibited the greatest influence on improvement in the QOL score. After DBS treatment, 40% of the patients showed significant improvement in urination symptoms (≥ 2 points reduction in QOL score), 30% of the patients showed mild improvement (1 point reduction in QOL score), and 30% patients showed no improvement (no change in QOL score). No patients exhibited worsening urination symptoms.Conclusion: Most parkinsonian female patients with lower urinary tract symptoms were diagnosed with OAB. DBS treatment improved OAB symptoms. Improvement of nocturia and urgency positively impacts the QOL of female parkinsonian patients.Keywords: Parkinson’s disease, urodynamics, OAB score, QOL score

Thus, we attempted to generate a risk score system according to the expression pattern of different EMT hallmark genes in head and neck squamous-cell carcinoma (HNSC).Methods: Differentially expressed EMT hallmark genes were screened to generate a risk score (RS) on TCGA HNSC dataset. The relative prognostic value of the RS compared to clinicopathological characteristics was explored using multivariable Cox analysis. Functional enrichment analysis was performed to reveal the biological characteristics. An external dataset was applied to validate the prognostic value of the RS.Results: Nine genes constituted the EMT hallmark gene-based RS, which is significantly associated with poor prognosis and could successfully divide patients with HNSC into high- and low-risk groups. The RS was also an independent prognostic indicator compared to routine clinical factors.Conclusion: We proposed and validated a nine-EMT hallmark gene-based risk score system in HNSC.Keywords: head and neck squamous-cell carcinoma, epithelial-to-mesenchymal transition, EMT, risk score system, angiogenesis

Fu Liang, Linlin Cao School of Business Administration, Shandong University of Finance and Economics, Jinan, People’s Republic of ChinaCorrespondence: Linlin Cao Email cll2021@163.comBackground: Environmental uncertainty has become the normal surviving and development environment for organizations. Resilience is the key to manage the crisis and abrupt crush, and the relationship between employee resilience and organizational resilience still needs to be explored in Chinese context. The study is to uncover the black box between employee resilience and organizational resilience.Methods: Based on the conservation of resource theory, this study introduced managerial resilience, problem-focused coping and emotion-focused coping into the relational mechanism between employee resilience and organizational resilience. The study adopted structural equations, bootstrapping methods, and analyzed 329 multi-point employee–manager matching data as the research basis from high-tech industries, service industries, and traditional manufacturing industries.Results: This study demonstrated that employee resilience is positively associated with organizational resilience; The indirect effects of employee resilience on organizational resilience through problem-focused coping and emotion-focused coping were statistically significant; moreover, managerial resilience positively moderated the relation between employee resilience and emotion-focused coping, and it also moderated the indirect effect of employee resilience on organizational resilience through emotion-focused coping.Conclusion: This study adds value to the literature by revealing employee resilience boots problem-focused coping and emotion-focused coping, resulting in more or less organizational resilience in the context of Chinese enterprises. It is suggested that in the daily management of the organization, we should pay more attention to cultivate and develop employee resilience to improve organizational resilience.Keywords: employee resilience, managerial resilience, problem-focused coping, emotion-focused coping, organizational resilience

We aim to build and validate a risk-based model so as to improve compliance and increase the benefits of screening.Patients and Methods: Using data from the Shanghai CRC screening cohort, we conducted a population-based nested case–control study to build a risk-based model. Cases of early colorectal neoplasm were extracted as colorectal adenomas and stage 0-I CRC. Each case was matched with five individuals without neoplasm (controls) by the screening site and year of enrollment. Cases and controls were then randomly divided into two groups, with two thirds for building the risk prediction model and the other one third for model validation. Known risk factors were included for risk prediction models using logistic regressions. The area under the receiver operating characteristic curve (AUC) and Hosmer–Lemeshow chi-square statistics were used to evaluate model discrimination and calibration. The predicted individual risk probability was calculated under the risk regression equation.Results: The model incorporating age, sex, family history and lifestyle factors including body mass index (BMI), smoking status, alcohol, regular moderate-to-intensity physical activity showed good calibration and discrimination. When the risk cutoff threshold was defined as 17%, the sensitivity and specificity of the model were 63.99% and 53.82%, respectively. The validation data analysis also showed well discrimination.Conclusion: A risk prediction model combining personal and lifestyle factors was developed and validated for high-risk early colorectal neoplasm among the Chinese population. This risk-based model could improve the pre-selection for screening and contribute a lot to efficient population-based screening in low-resource countries.Keywords: cancer prevention, colorectal cancer, risk model, screening

Peng Xu, Feng Liang The State Key Laboratory of Refractories and Metallurgy, Coal Conversion and New Carbon Materials Hubei Key Laboratory, School of Chemistry and Chemical Engineering, Wuhan University of Science and Technology, Wuhan 430081, People’s Republic of ChinaCorrespondence: Feng Liang Email feng_liang@whu.edu.cnAbstract: In recent years, photothermal therapy (PTT) particularly nanomaterial-based PTT is a promising therapeutic modality and technique for cancer tumor ablation. In addition to killing tumor cells directly through heat, PTT also can induce immunogenic cell death (ICD) to activate the whole-body anti-tumor immune response, including the redistribution and activation of immune effector cells, the expression and secretion of cytokines and the transformation of memory T lymphocytes. When used in combination with immunotherapy, the efficacy of nanomaterial-based PTT can be improved. This article summarized the mechanism of nanomaterial-based PTT against cancer and how nanomaterial-based PTT impacts the tumor microenvironment and induces an immune response. Moreover, we reviewed recent advances of nanomaterial-based photothermal immunotherapy and discussed challenges and future outlook.Keywords: nanomaterials, cell death mechanism of PTT, tumor microenvironment, immunogenic cell death, photothermal immunotherapy
