Objective To observe the expression of serum carcinoembryonic antigen(CEA)and interleu-kin-35(IL-35)in patients with differentiated thyroid cancer(DTC),and to analyze the correlation between them and lung metastasis.Methods A total of 150 patients with DTC treated in the hospital from January 2018 to December 2021 were selected as the case group,and another 150 healthy individuals who underwent the physical examination in the hospital in December 2021 were selected as the control group.The case group was divided into lung metastasis group and non lung metastasis group according to the occurrence of lung me-tastasis.The clinical data,serum CEA,IL-35 levels and other laboratory indexes in each group were counted,the correlation between the expression of serum CEA and IL-35 and lung metastasis of DTC patients was ana-lyzed,and the evaluation value of receiver operating characteristic(ROC)curve and area under curve(AUC)on lung metastasis of DTC patients was evaluated.Results The serum CEA level in the case group was higher than that in the control group,and the serum IL-35 level was lower than that in the control group,and the differences were statistically significant(P＜0.05).Among 150 patients with DTC,25 cases had lung metas-tasis,accounting for 16.67％.The levels of serum thyroid stimulating hormone,thyroglobulin and CEA in pa-tients with DTC in lung metastasis group were higher than those in non lung metastasis group,and the level of serum IL-35 was lower than that in non lung metastasis group,and the differences were statistically significant(P＜0.05).The correlation analysis showed that there was a positive correlation between the expression of serum CEA in DTC patients and lung metastasis(r=0.580,P＜0.001),and there was a negative correlation between serum IL-35 and lung metastasis(r=-0.283,P＜0.001).ROC curve analysis was drawn and showed that the area under the curve(AUC)of serum CEA and IL-35 alone and in combination for predicting lung metastasis in patients with DTC were 0.906,0.711 and 0.936 respectively,the sensitivity corresponding to the cut off value was 0.760,0.840 and 0.840 respectively,and the specificity was 0.984,0.544 and 0.968 respectively.Conclusion There is a certain correlation between the expression of serum CEA and lung metas-tasis in DTC patients.Although serum IL-35 is related to lung metastasis,the correlation is extremely weak.The combination of serum CEA and IL-35 has the potential to be used for the evaluation of clinical DTC lung metastasis.

Objective:To analyze the mediating effects of psychological resilience on the relationship between perceived social support and health behavior capacity in patients with ischemic stroke.Methods:In this cross-sectional study, 500 patients with ischemic stroke were consecutively recruited using purposive sampling in the First People′s Hospital of Lianyungang between July and September in 2023. The sociodemographic characteristics, perceived social support scale, psychological resilience questionnaire and self-rated abilities for health practices scale in the patients were collected. A total of 500 questionnaires were distributed and 493 questionnaires were collected, of which 473 (95.9%) were valid. The structural equation model was constructed to explore the mediating effects of psychological resilience on the relationship between perceived social support and health behavior capacity in patients with ischemic stroke.Results:Among the 473 patients included in the analysis, there were 254 males and 219 females, with an average age of (66.8±11.4) years. The duration of stroke was less than 3 months for 329 patients (69.6%); the scores for perceived social support, psychological resilience and health behavior capacity was (59.68±11.15), (23.68±6.52), and (60.54±23.52), respectively. Perceived social support exerted significant direct effect ( β=0.334, bias-corrected 95% CI: 0.232-0.438) on health behavior capacity in patients with ischemic stroke, accounting for 63.62% of the total effect. Psychological resilience played a mediating role in the relationship between perceived social support and health behavior capacity ( β=0.191, bias-corrected 95% CI: 0.142-0.248), accounting for 36.38% of the total effect (all P<0.05). Conclusion:The health behavior capacity of patients with ischemic stroke is at a moderately low level, perceived social support may positively affect health behavior capacity through the positive mediating effect of psychological resilience.

Purpose To investigate the clinicopathological features and differential diagnosis of anaplastic large-cell lymphoma(ALCL)with the small cell variant.Methods The clinical data of 15 cases of small cell variant of ALCL were retrospectively analyzed.Hematoxylin-eosin staining,immunohistochemistry,EBER in situ hybridization,TCR and IgG rearrangement were performed.The clinicopathological features,prognosis and differential diagnosis were summarized with review of the literature.Results Among the 15 cases of small cell ALCL,5 were females and 10 were males,with a male-to-female ratio of 2:1.Among the 15 cases of small cell ALCL,14 were systemic ALCL[(12 cases of ALK+),and the age range was 5-63 years old(median age 20 years);There were 2 cases of ALK(-),aged more than 60 years],and 1 case of ALCL of primary cutaneous ALK(-).Microscopic features were dominated by small to medium-sized tumor cells,with irregular nuclear membranes,inconspicuous nucleoli,and a lack of or few iconic large cells.Immunohistochemically:3 cases were ALK-negative and 12 cases were ALK-positive.Tumor cells were CD30 positive in 14/15 cases,CD3 positive in 7/15 cases,CD2 positive in 2/6 cases,CD4 positive in 5/11 cases,CD5 positive in 2/8 cases,CD7 positive in 4/6 cases,CD8 positive in 1/8 cases,TIA-1 positive in 7/7 cases,Granzyme B positive in 4/6 cases and EMA positive in 6/7 cases.CD20 was negative in all cases.Immuno-globulin IgG and TCR gene rearrangement were negative in case 4 and case 11.Case 13 was positive for TCR rear-rangement and negative for immunoglobulin IgG.Twelve of the 15 patients were followed up for 0.7-165 months(me-dian,7 months),3 patients were lost to follow-up and 7 patients died.Conclusion Small cell variant ALCL is easily misdiagnosed as an inflammatory or infectious disease.A group of antibodies,including CD30 and ALK,should be routinely used in routine work,especially in young patients with systemic symptoms and leukemia manifestations or in small biopsies,to reduce misdiagnosis and missed diagnosis.

In recent years, increasing evidence has shown that hyperthermia is safe, effective and causes low toxicity. Hyperthermia can exert synergistic effect with other treatments, such as radiotherapy and chemotherapy. It has become an important adjuvant anti-tumor treatment secondary to surgery, chemotherapy, radiotherapy and biological treatment. Hyperthermia can improve the efficacy of radiotherapy and chemotherapy by directly inhibiting tumor cells and heat-induced radiosensitizing effect. Hence, hyperthermia is gradually applied in the multimodality treatment of tumors. In this article, we intend to review the research progress on the application of tumor hyperthermia in conventional radiotherapy, chemotherapy, immunotherapy and new biomaterials.

As the main type of lung cancer, non-small cell lung cancer (NSCLC) is a common cancer which is characterized by low 5-year survival rate and worse prognosis. Nowadays, some studies show that the low survival rate and worse prognosis are due to the resistance to radiotherapy caused by circRNA. Therefore, to find out the relationship between circRNA and radiotherapy resistance of NSCLC was imoprtant. According to research the relevant literatures, the relationship between circRNA and radiotherapy resistance of NSCLC was explored. CircRNA plays an important role in the invasion, metastasis, proliferation and treatment resistance of NSCLC. The radiation resistance of tumor cells induced by circRNA has become a crucial problem in radiotherapy. CircRNA plays an important role in the radiotherapy resistance of NSCLC.
