Background Unhealthy lifestyle behaviors may be associated with an increased risk of cardiometabolic risk factor aggregation (CMRF≥ 2), and few studies have focused on the correlation between the two in occupational populations. Objective To investigate the current status of CMRF≥2 and the compliance of healthy lifestyle in male occupational personnel, explore the effect of lifestyle on cardiometabolic risk, and provide reference for formulating healthy behavior promotion strategies and reducing cardiometabolic risk in occupational populations. Methods The study subjects were selected from male workers who completed occupational health examinations at an occupational disease prevention and control hospital in Shanxi Province from May to December 2023, and 15125 study subjects aged 18−60 years were finally included according to pre-determined inclusion and exclusion criteria. All subjects received a series of assessments including questionnaires (basic information, lifestyle habits, and occupational factors), physical examination, laboratory tests, and six cardiometabolic risk factors (central obesity, hypertension, type 2 diabetes, hypertriglyceridemia, low-density lipoprotein cholesterolemia, and hyperuricemia). A healthy lifestyle score was calculated based on six behavioral factors (smoking, drinking, physical activity, diet, sleep, sedentary behavior) and 1 point for one positive healthy behavior. The enrolled workers were then divided into three groups according to their total scores: 0−1 points (poor group), 2−3 points (moderate group), and 4−6 points (good group). Logistic regression models were used to analyze the statistical associations between lifestyle and CMRF≥2. Results The median age of the 15125 male study participants was 40 years, and the positive rate of CMRF≥2 was 53.5%. Adherence to moderate alcohol consumption was the most compliant healthy behavior (79.4%), followed by current non-smoking (41.7%), while adherence to adequate sedentary behavior (23.6%) and healthy eating (21.1%) were relatively low, and only 17.4% were able to adhere to four or more healthy lifestyle behaviors. After adjusting for confounders, when compared with the poor group high lifestyle score was found to be a protective factor for CMRF≥2 (moderate group: OR=0.70, 95%CI: 0.63, 0.77; good group: OR=0.66, 95%CI: 0.58, 0.75). In stratified analyses across different job types (coal miners, auxiliary workers, ground workers, and others), occupational stress (with or without), shift patterns (day shift, night shift, or rotating shift), dust exposure (with or without), and noise exposure (with or without), individuals with higher lifestyle scores exhibited a consistently lower risk of CMRF≥2. There was an interaction between shift pattern and lifestyle on CMRF≥2 (P_interaction<0.05). Conclusion This occupational group has a high positive rate of CMRF≥2 and a high prevalence of poor lifestyles with low adherence to some healthy behaviors. High healthy lifestyle scores are associated with a lower risk of aggregation of cardiometabolic risk factors, which may be reduced through lifestyle interventions.

CD47 is a transmembrane protein widely expressed on cell surface, which is considered as a key molecule for immune escape. With an increasing number of related studies, the role of CD47 and its ligands in immunomodulatory effects has been gradually understood. Recent studies have investigated the role of CD47 in ischemia-reperfusion injury of allogenetic kidney transplantation, rejection and xenotransplantation. Nevertheless, the specific role and the key mechanism remain elusive. In this article, the structure and function of CD47, common CD47 ligands, the relationship between CD47 and kidney transplantation, and the application of CD47 in kidney transplantation were reviewed, the latest research progress of CD47 in kidney transplantation was summarized, and the limitations of current research and subsequent research direction were analyzed, aiming to provide reference for subsequent application of CD47 in allogeneic and kidney xenotransplantation.

ObjectiveTo investigate the safety and efficacy of endoscopic ultrasound-guided tissue adhesive injection with the assistance of metal clips in the treatment of cirrhotic patients with gastric varices and gastric-renal shunt （GRS）. MethodsThe patients who attended Beijing Ditan Hospital， Capital Medical University， due to liver cirrhosis and gastric varices from February to June 2023 were enrolled， and all patients were confirmed to have GRS and received endoscopic ultrasound-guided tissue adhesive injection with the assistance of metal clips. The primary evaluation index was alleviation or disappearance of varicose veins after surgery， and the secondary evaluation indices were surgical completion and complications. ResultsA total of 11 patients were enrolled in this study， among whom there were 7 male patients and 4 female patients， with a median age of 55 years. Of all patients， 1 had Child class A liver function， 7 had Child class B liver function， and 3 had Child class C liver function. The maximum （median） diameter of the shunt was 8 mm， and the minimum （median） diameter of the shunt was 4 mm. The median blood flow velocity of the target vessel was 11 cm/s before treatment and 5 cm/s after occlusion with metal clips. The median amount of tissue adhesive injected was 2 mL， and the amount of lauromacrogol used was 1 mL. Disappearance of blood flow signals was observed in all patients after surgery （100%）， and the success rate of surgery was 100%. No patient experienced rebleeding after follow-up for 6 weeks. Gastroscopy at 1 month after surgery showed that gastric varices were eradicated or almost disappeared in 9 patients and were alleviated in 2 patients. ConclusionEndoscopic ultrasound-guided tissue adhesive injection with the assistance of metal clips is a feasible， safe， and effective treatment method for cirrhotic patients with gastric varices and GRS.

ObjectiveTo observe the apoptosis induced by paeoniflorin （PF） in non-small cell lung cancer （NSCLC） cells and explore its mechanism. MethodCell counting kit-8 （CCK-8） was used to detect the inhibition rates of H1299， H292 and A549 cells with different concentrations of PF （2.5， 5， 10， 20， 25 µmol·L^-1）， and to screen suitable concentrations of PF and experimental cells. The inhibitory effect of PF on lung cancer cells was detected by clone formation assay. The effect of PF on cell apoptosis was detected by flow cytometry with annexin V-FITC/propidium iodide （PI） double staining. With the right concentration of drugs， levels of apoptosis-associated protein B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， cleaved Caspase-3 and Caspase-3 were detected by Western blot. At the same time， the molecular expressions of hypoxia inducible factor -1α （HIF-1α） and Hippo signaling pathway were determined. ResultCompared with the blank group， PF significantly inhibited the growth of H1299， H292 and A549 cells of human lung cancer （P<0.01）. PF significantly induced apoptosis in A549 cells （P<0.01）， decreased the Bcl-2/Bax ratio （P<0.01）， and significantly increased the cleaved Caspase-3 expression （P<0.01）. Compared with those in the blank group， the expression levels of HIF-1α， transcriptional coactivator with PDZ-binding motif （TAZ）， large tumor suppressor 1 （LATS1）， Mps one binding 1 （MOB1） and Yes-associated protein （YAP） in A549 cells of the PF treatment group were significantly decreased （P<0.01）， while the expressions of p-LATS1， p-MOB1 and p-YAP were significantly increased （P<0.01）. At the same time， there was no significant effect on the expression levels of phosphorylated mammalian Ste20-like kinase 1 （p-MST1） and MST1， which did not reach a statistical difference. ConclusionAll data demonstrated that PF showed an anti-tumor effect by improving hypoxic conditions and inhibiting the abnormally activated Hippo signaling pathway， thereby inducing and promoting apoptosis in non-small cell lung cancer.

Objective:To investigate the prognosis of patients with initially resectable gastric cancer liver metastasis (GCLM) who were treated by different modalities, and analyze the influencing factors for prognosis of patients.Methods:The retrospective cohort study was conducted. The clinicopathological data of 327 patients with initially resectable GCLM who were included in the database of a nationwide multicenter retrospective cohort study on GCLM based on real-world data from January 2010 to December 2019 were collected. There were 267 males and 60 females, aged 61(54,68)years. According to the specific situations of patients, treatment modalities included radical surgery combined with systemic treatment, palliative surgery combined with systemic treatment, and systemic treatment alone. Observation indicators: (1) clinical characteristics of patients who were treated by different modalities; (2) prognostic outcomes of patients who were treated by different modalities; (3) analysis of influencing factors for prognosis of patients with initially resectable GCLM; (4) screening of potential beneficiaries in patients who were treated by radical surgery plus systemic treatment and patients who were treated by palliative surgery plus systemic treatment. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. The Kaplan-Meier method was used to calculate survival rate and draw survival curve, and Log-Rank test was used for survival analysis. Univariate and multivariate analyses were conducted using the COX proportional hazard regression model. The propensity score matching was employed by the 1:1 nearest neighbor matching method with a caliper value of 0.1. The forest plots were utilized to evaluate potential benefits of diverse surgical combined with systemic treatments within the population. Results:(1) Clinical characteristics of patients who were treated by different modalities. Of 327 patients, there were 118 cases undergoing radical surgery plus systemic treatment, 164 cases undergoing palliative surgery plus systemic treatment, and 45 cases undergoing systemic treatment alone. There were significant differences in smoking, drinking, site of primary gastric tumor, diameter of primary gastric tumor, site of liver metastasis, and metastatic interval among the three groups of patients ( P<0.05). (2) Prognostic outcomes of patients who were treated by different modalities. The median overall survival time of the 327 pati-ents was 19.9 months (95% confidence interval as 14.9-24.9 months), with 1-, 3-year overall survival rate of 61.3%, 32.7%, respectively. The 1-year overall survival rates of patients undergoing radical surgery plus systemic treatment, palliative surgery plus systemic treatment and systemic treatment alone were 68.3%, 63.1%, 30.6%, and the 3-year overall survival rates were 41.1%, 29.9%, 11.9%, showing a significant difference in overall survival rate among the three groups of patients ( χ2=19.46, P<0.05). Results of further analysis showed that there was a significant difference in overall survival rate between patients undergoing radical surgery plus systemic treatment and patients undergoing systemic treatment alone ( hazard ratio=0.40, 95% confidence interval as 0.26-0.61, P<0.05), between patients undergoing palliative surgery plus systemic treatment and patients under-going systemic treatment alone ( hazard ratio=0.47, 95% confidence interval as 0.32-0.71, P<0.05). (3) Analysis of influencing factors for prognosis of patients with initially resectable GCLM. Results of multivariate analysis showed that the larger primary gastric tumor, poorly differentiated tumor, larger liver metastasis, multiple hepatic metastases were independent risk factors for prognosis of patients with initially resectable GCLM ( hazard ratio=1.20, 1.70, 1.20, 2.06, 95% confidence interval as 1.14-1.27, 1.25-2.31, 1.04-1.42, 1.45-2.92, P<0.05) and immunotherapy or targeted therapy, the treatment modality of radical or palliative surgery plus systemic therapy were independent protective factors for prognosis of patients with initially resectable GCLM ( hazard ratio=0.60, 0.39, 0.46, 95% confidence interval as 0.42-0.87, 0.25-0.60, 0.30-0.70, P<0.05). (4) Screening of potentinal beneficiaries in patients who were treated by radical surgery plus systemic treatment and patients who were treated by palliative surgery plus systemic treatment. Results of forest plots analysis showed that for patients with high-moderate differentiated GCLM and patients with liver metastasis located in the left liver, the overall survival rate of patients undergoing radical surgery plus systemic treatment was better than patients undergoing palliative surgery plus systemic treatment ( hazard ratio=0.21, 0.42, 95% confidence interval as 0.09-0.48, 0.23-0.78, P<0.05). Conclusions:Compared to systemic therapy alone, both radical and palliative surgery plus systemic therapy can improve the pro-gnosis of patients with initially resectable GCLM. The larger primary gastric tumor, poorly differen-tiated tumor, larger liver metastasis, multiple hepatic metastases are independent risk factors for prognosis of patients with initial resectable GCLM and immunotherapy or targeted therapy, the treatment modality of radical or palliative surgery plus systemic therapy are independent protective factors for prognosis of patients with initially resectable GCLM.

Approximately 25%of cancers worldwide are related to obesity and sedentary lifestyle.Changing behavior(exer-cise)may be a cost-effective means of prevention and treatment.Studies have found that exercise plays an important role in reducing cancer risk,inhibiting tumor growth,improving cancer-related quality of life,and improving the effectiveness of treatment.However,this protection mechanism is largely unclear.Clarifying the mechanism of action is essential to fully exploit the potential of exercise therapy,this article reviews the possible mechanisms for exercise to reduce the risk of cancer.

Objective:To compare the differences of actual absorbed doses of liver malignant tumors after 90Y-selective internal radiation therapy (SIRT) evaluated by 90Y PET/CT and 90Y bremsstrahlung (BRS) SPECT/CT imaging, and to compare the image quality of the 2 imaging methods. Methods:Twenty-one patients (15 males and 6 females; age: (52.4±15.4) years) with liver malignant tumors (15 cases of primary liver cancer, 6 cases of liver metastases; 39 lesions) between September 2021 and August 2022 were retrospectively analyzed. All patients underwent both 90Y PET/CT imaging and 90Y BRS SPECT/CT imaging in the Department of Nuclear Medicine, Hainan Cancer Hospital. The ratios of the actual absorbed doses based on 90Y PET/CT imaging and 90Y BRS SPECT/CT imaging to the lowest standard absorbed dose(100 Gy) for tumor response were calculated. The image contrast and distinguishability of the two imaging methods were scored. Wilcoxon signed rank test and Wilcoxon rank sum test were used for data analysis. Results:The tumor absorbed doses evaluated by 90Y PET/CT and 90Y BRS SPECT/CT were 143.94(55.91, 233.48) Gy and 107.82(53.59, 157.53) Gy respectively. The doses evaluated by 90Y PET/CT were higher than the standard threshold in 24 lesions, while 19 lesions showed higher evaluated doses by 90Y BRS SPECT/CT than the standard threshold. Compared with 90Y PET/CT, 90Y BRS SPECT/CT underestimated the tumor absorbed dose of -24.25%(-32.32%, -12.14%). The ratio of dose evaluated by 90Y PET/CT to the lowest standard threshold was 1.33(0.56, 1.91), which was higher than that of dose evaluated by 90Y BRS SPECT/CT to the lowest standard threshold (0.97(0.47, 1.25); z=0.04, P<0.001). PET/CT image contrast was scored 0, 1, 2, 3 in 2, 2, 12, 23 lesions respectively, and SPECT/CT image contrast was scored 0, 1, 2, 3 in 2, 3, 16, 18 lesions respectively ( z=-1.29, P=0.199). The distinguishability scores of 0, 1, 2 based on PET/CT images were found in 3, 15, 21 lesions, while those based on SPECT/CT images were found in 4, 32, 3 lesions respectively ( z=-2.79, P=0.005). Conclusion:90Y PET/CT imaging is superior to 90Y BRS SPECT/CT imaging in radiation dose evaluation and tumor focus differentiation in patients with liver malignant tumors after 90Y-SIRT.

Objective:To investigate the effect of immune checkpoint inhibitors on reducing residual lymph node metastasis in patients with gastric cancer.Methods:The cohort of this retrospective study comprised patients from Nanfang Hospital of Southern Medical University and the First Affiliated Hospital of Xiamen University who had undergone systemic treatment prior to gastrectomy with D2 lymphadenectomy and had achieved Grade 1 primary tumor regression (TRG1) from January 2014 to December 2023. After exclusion of patients who had undergone preoperative radiotherapy, data of 58 patients (Nanfang Hospital: 46; First Affiliated Hospital of Xiamen University: 12) were analyzed. These patients were allocated to preoperative chemotherapy (Chemotherapy group, N=36 cases) and preoperative immunotherapy plus chemotherapy groups (Immunotherapy group, N=22 cases). There were no significant differences between these groups in sex, age, body mass index, diabetes, tumor location, pathological type, Lauren classification, tumor differentiation, pretreatment depth of invasion by primary tumor, pretreatment lymph node stage, pretreatment clinical stage, mismatch repair protein status, number of preoperative treatment cycles, or duration of preoperative treatment (all P>0.05). The primary outcome measure was postoperative lymph node downstaging. Secondary outcomes included postoperative depth of invasion by tumor, number of lymph nodes examined, and factors affecting residual lymph node metastasis status. Results:Lymph node downstaging was achieved significantly more often in the Immunotherapy group than the Chemotherapy group (pN0: 90.9% [20/22] vs. 61.1% [22/36]; pN1: 4.5% [1/22] vs. 36.1% [13/36]; pN2: 4.5% [1/22) vs. 0; pN3: 0 vs. 2.8% [1/36], Z=-2.315, P=0.021). There were no significant difference between the two groups in number of lymph nodes examined (40.5±16.3 vs. 40.8±17.5, t=0.076, P=0.940) or postoperative depth of invasion by primary tumor (pT1a: 50.0% [11/22] vs. 30.6% [11/36]; pT1b: 13.6% [3/22] vs. 19.4% [7/36]; pT2: 13.6% [3/22] vs. 13.9% [5/36]; pT3: 13.6% [3/22] vs. 25.0% [9/36]; pT4a: 9.1% [2/22] vs. 11.1% [4/36], Z=-1.331, P=0.183). Univariate analysis revealed that both preoperative treatment regimens were associated with residual lymph node metastasis status in patients whose primary tumor regression was TRG1 (χ 2=6.070, P=0.014). Multivariate analysis incorporated the following factors: pretreatment depth of invasion by primary tumor, pretreatment lymph node stage, pretreatment clinical stage, number of preoperative treatment cycles, and preoperative treatment duration. We found that a combination of immunotherapy and chemotherapy administered preoperatively was an independent protective factor for reducing residual lymph node metastases in study patients whose primary tumor regression was TRG1 (OR=0.147, 95%CI: 0.026–0.828, P=0.030). Conclusion:Compared with preoperative chemotherapy alone, a combination of preoperative immunotherapy and chemotherapy achieved greater reduction of residual lymph node metastases in the study patients who achieved TRG1 tumor regression in their primary lesions.

OBJECTIVE To introduce a case of interstitial pneumonia induced by vedolizumab （VDZ）， summarize and analyze the characteristics of the occurrence of VDZ-associated lung toxicity， and provide a reference for the clinically safe use of drugs. METHODS From the perspective of clinical pharmacists， the diagnosis and treatment of a case of VDZ-induced interstitial pneumonia were retrospectively analyzed， and the association of adverse drug reactions （ADR） was analyzed. Retrieving from Chinese and English databases such as CNKI， VIP， PubMed and Web of Science， case reports of VDZ-associated lung toxicity were summarized and analyzed. RESULTS The patient developed interstitial pneumonia during the use of VDZ and empirical anti- infective therapy with antibiotics was ineffective. After withdrawal of VDZ and treatment with methylprednisolone， symptoms and imaging examinations improved， but interstitial pneumonia still existed. According to Naranjo’s ADR evaluation scale and based on China Adverse Drug Reaction Reporting and Monitoring Manual， the association between VDZ and interstitial pneumonia was “very likely”. Results of the literature analysis showed that among 29 involved patients （including the patient reported in this article）， there were 19 males and 10 females， with an average age of （49.24±17.06） years. Lung toxicity mainly included VDZ- associated pneumonia， eosinophilic pneumonia， pulmonary granulomas or necrobiotic nodules， interstitial lung injury， etc.， which mostly occurred ≤24 weeks after medication （58.62%）. The main clinical manifestations included cough， dyspnea and fever. The vast majority of patients improved or recovered after drug withdrawal and/or glucocorticoid treatment， but one patient died of respiratory failure. CONCLUSIONS Lung toxicity is a rare ADR of VDZ with insidious onset and nonspecific symptoms. Once patients experience symptoms such as cough and dyspnea， early diagnosis，timely drug withdrawal，and symptomatic treatment measures such as glucocorticoid should be taken to ensure medication safety.

Objective: To analyze the association of strength quality of junior high school students with comorbid depressive and anxiety (CDA) and its subtypes, so as to provide reference for mental health improvement among junior high students. Methods: A convenient sampling method was used to select 10 007 junior high students aged 13-16 from four cities (Nanchang, Ganzhou, Jiujiang, Shangrao) in Jiangxi Province during September to November 2023. A questionnaire survey and physical fitness tests were employed to collect basic information and assess students depressive and anxiety status, as well as strength quality. The χ 2 test was used to compare the distribution differences of CDA and its subtypes among different demographic characteristics, sleep, physical activity, and overweight/obesity conditions. Logistic regression models were applied to infer the association strength between strength quality and CDA and its subtypes. Results: The overall detection rate of CDA among junior high students was 11.04%. Among the CDA subtypes, the detection rates for mild depression-mild anxiety type, anxiety dominant type, depressiondominant type, and severe depression-severe anxiety type were 3.67%, 3.35%, 0.39% and 3.64%, respectively. Compared to the grip strength and standing long jump scores in the > P 75 group, the risk of CDA occurrence increased in other groups (grip strength: P 25 - P 75 , OR =1.20; < P 25 , OR =1.28; standing long jump: P 25 - P 75 , OR =1.31; < P 25 , OR =1.51; P <0.05). In stratified analysis of different CDA subtypes, compared to the grip strength > P 75 group, the risks for mild depression-mild anxiety type increased in the P 25 - P 75 and < P 25 groups ( OR=1.32, 1.44, P <0.05). Compared to the standing long jump > P 75 group, the risks for anxiety dominant type and severe depression-severe anxiety type increased in other groups (anxiety dominant type: P 25 - P 75 , OR =1.32; severe depression-severe anxiety type: < P 25 , OR =1.87; P < 0.05 ). Conclusions Lower levels of grip strength and standing long jump performance among junior high students are positively correlated with CDA and its subtypes. Lower levels of lower limb strength may be an important predictor of CDA in severe depression and anxiety.
