BACKGROUND: The incidence and mortality rates of lung cancer remain on the rise, creating an urgent need for screening among high-risk populations and early prevention. This study aims to explore the association and interaction between multidimensional lifestyle, socioeconomic status, and the incidence of lung cancer, and to provide scientific evidence for screening high-risk populations and preventing lung cancer. METHODS: Healthy lifestyle score was constructed using information on smoking, alcohol consumption, exercise, diet and sleep obtained through a questionnaire survey. Socioeconomic status was evaluated based on information on education, employment, and family income, and genetic testing data were used to assess the risk of genetic variation. A proportional hazards assumption test was conducted, and the Cox proportional hazards model was applied to analyze the associations between healthy lifestyle scores, socioeconomic status, and lung cancer, as well as the interactions among various factors, after adjusting for the risk of genetic variation, age, gender, diabetes, hypertension and the living environment score. RESULTS: A total of 245,538 samples that entered the cohort from March, 2006 to October, 2010 were included and followed up until December 31, 2022. The participants were divided into the case group (n=1472) and the control group (n=244,066). The analysis results showed that after adjusting for covariates, there was still an association between the healthy lifestyle score, socioeconomic status, and the incidence of lung cancer: compared with participants with a high healthy lifestyle score, the risk of lung cancer in participants with medium and low healthy lifestyle scores was significantly increased, with hazard ratios (HR) of 2.12 (95%CI: 1.86-2.41) and 3.36 (95%CI: 2.82-3.99) respectively; compared with participants with high socioeconomic status, the risk of lung cancer in participants with medium and low socioeconomic status was significantly increased, with HR of 1.29 (95%CI: 1.13-1.48) and 1.67 (95%CI: 1.46-1.90) respectively. Moreover, there were interactions between smoking status and socioeconomic status (Pfor interaction=0.05), as well as the other four lifestyle factors (Pfor interaction=0.02). CONCLUSIONS This study identified the association between multidimensional lifestyle factors and socioeconomic status with the incidence of lung cancer, as well as interactions between smoking and socioeconomic status and four other lifestyle factors, providing a scientific basis for screening and prevention in high-risk populations for lung cancer.

Stearoyl-coenzyme A desaturase 1 (SCD1) catalyzes the rate-limiting step of de novo lipogenesis and modulates lipid homeostasis. Although numerous SCD1 inhibitors were tested for treating metabolic disorders both in preclinical and clinic studies, the tissue-specific roles of SCD1 in modulating obesity-associated metabolic disorders and determining the pharmacological effect of chemical SCD1 inhibition remain unclear. Here a novel role for intestinal SCD1 in obesity-associated metabolic disorders was uncovered. Intestinal SCD1 was found to be induced during obesity progression both in humans and mice. Intestine-specific, but not liver-specific, SCD1 deficiency reduced obesity and hepatic steatosis. A939572, an SCD1-specific inhibitor, ameliorated obesity and hepatic steatosis dependent on intestinal, but not hepatic, SCD1. Mechanistically, intestinal SCD1 deficiency impeded obesity-induced oxidative stress through its novel function of inducing metallothionein 1 in intestinal epithelial cells. These results suggest that intestinal SCD1 could be a viable target that underlies the pharmacological effect of chemical SCD1 inhibition in the treatment of obesity-associated metabolic disorders.

BACKGROUND:Large deep burn wounds are often accompanied by scar hyperplasia after healing,requiring transplantation of medium-thickness skin for repair,and the medium-thickness skin slices taken generally reach below the papillary layer of the dermis.If not handled correctly,complications such as delayed healing,ulceration,and post-healing pain and itching in the donor area can easily occur.Therefore,the repair of wounds in the donor area should be emphasized.OBJECTIVE:To observe the safety and practicability of autologous scalp repair of skin donor area in patients with deep burns and scarring.METHODS:Sixty patients with deep burn and scar hyperplasia admitted to the Burn Department of Zhengzhou First People's Hospital from January 2021 to September 2023 were selected as the study subjects.They all needed medium-thickness skin transplantation and repair,and were divided into study group(n=30)and control group(n=30)according to random systematic sampling method.The skin was taken from the patient's own medium-thickness skin on the leg or back.In the study group,the skin donor area was repaired with self-blade thick scalp replantation,and in the control group,the skin donor area was repaired with absorbent dressing.The wound healing rate and the time to complete epithelialization of the wound were observed and compared in the two groups 6 days after surgery.The pain of dressing change at 3 and 6 days after surgery and scar hyperplasia in the skin donor area at 6 months after surgery were compared between two groups.RESULTS AND CONCLUSION:Compared with the control group,the time to complete epithelialization of the wound was significantly lower in the study group(P<0.05),and the wound healing rate was significantly higher in the study group(P<0.05),the pain score for dressing change at 3 and 6 days after surgery was significantly lower in the study group(P<0.05),and the scar hyperplasia rate,scar score and itch score were also significantly lower in the study group(P<0.05)at 6 months after surgery.In conclusion,autologous scalp repair of the medium-thickness skin donor area can accelerate wound healing and reduce scar hyperplasia.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

Objective To investigate the correlation between the expression of cysteine protease inhibitor S(CST4)and vascular endothelial growth factor-A(VEGF-A)in esophageal squamous cell carcinoma(ESCC)and clinical pathological parameters.Methods Immunohistochemistry was used to detect the expression of CST4 and VEGF-A in the tissues of 50 patients with ESCC,and the correla-tion between them and pathological parameters was analyzed.The enrichment and correlation of them were confirmed by combining the re-sults of Enrichr and GEO databases.Results Compared with adjacent tissues,the positive expression rates of CST4 and VEGF-A in ESCC was significantly increased(P＜0.05).There were significant differences in the positive expression rate of CST4 in ESCC with dif-ferent lymph node metastasis,depth of invasion,and neurovascular invasion(P＜0.05).There were significant differences in the positive expression rate of VEGF-A in ESCC with different lymph node metastasis,depth of invasion,neurovascular invasion,and pathological stage(P＜0.05).Kaplan-Meier survival analysis indicated that postoperative survival rate of patients was related to the expression of CST4 and VEGF-A,depth of invasion,TNM stage and lymph node metastasis(P＜0.05).Spearman correlation analysis showed a pos-itive correlation between the expression of CST4 and VEGF-A in ESCC tissues(r=0.601,P＜0.05).COX regression analysis showed that VEGF-A expression level,CST4 expression level,lymph node metastasis,depth of invasion and pathological stage were risk factors for survival(P＜0.05).Enrichment analysis showed that CST4 and VEGF-A play a synergistic role in cell migration and invasion.Conclusion CST4 and VEGF-A are higher expressed in ESCC tissues than normal tissues.They are involved in the development and metastasis of ESCC,and they are expected to be important indicators for the treatment and prognosis of ESCC.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
