Objective: To evaluate the relationship between visceral pleural invasion (VPI) and other clinicopathological features in lung adenocarcinoma with tumor size ≤3 cm, and to investigate the impact of VPI on the patients′ prognosis. Methods: The clinical and pathological features were retrospectively reviewed in 231 cases of lung adenocarcinoma with the largest diameter of tumor ≤3 cm, following complete resection and systemic lymphadenectomy. VPI was divided into three grades, PL0, PL1 and PL2 according to modified Hammar classification for lung cancer upon elastic fiber staining. Survival analysis was performed by Kaplan-Meier method, and the risk factors for prognosis were explored by Cox proportional hazards model. Patient prognosis was evaluated by progression-free survival (PFS) and overall survival (OS). Results: In all 231 cases, the number of patients with VPI was 70 (30.3%), of which 61 cases were PL1 and 9 cases were PL2. The remaining 161 cases (69.7%) had no VPI (PL0). The tumor size (P=0.003), histological grade (P<0.01), the presence of solid component (P=0.001) and micropapillary component (P=0.009), N stage (P<0.01) and TNM stage (P<0.01) were significantly correlated with VPI. Patients with VPI had significantly shorter PFS and OS than those without VPI (P<0.01). There were significant differences in PFS and OS between patients with different VPI levels (P<0.01). Cox multivariate regression analysis showed that VPI was not an independent prognostic factor, whereas PL2 was an independent prognostic factor for PFS (P=0.007), but not an independent prognostic factor for OS (P=0.052). Conclusions For patients with lung adenocarcinoma of tumor size ≤3 cm, VPI is related to poor prognosis; However, only PL2 is an independent prognostic factor for PFS. It may be not necessary to separate PL0 and PL1 status in smaller lung adenocarcinomas. Therefore, the definition of VPI may need further modification through large cohort studies.

Objective:To investigate the status of depression and physiological, psychological and social factors among people with type 2 diabetes(T2DM), as well as the mediating effects of illness perception and diabetes distress on glycemic control and depression.Methods:A total of 511 patients with type 2 diabetes were recruited and investigated using general demographic questionnaire, self-rating depression scale(SDS), brief illness perception questionnaire(BIPQ) and diabetes distress scale(DDS). Body mass index (BMI) and hemoglobin a1c (HbA1c) were detected in laboratory.Results:The mean score of SDS was (57.48±9.94). The distribution of depression condition were 138(27.0%)without depression, 179(35%)with mild depression, 174(34.1%)with moderate depression and 20(3.9%)with severe depression.SDS score was significantly positively correlated with poor glycemic control ( r=0.157, P<0.01), illness perception( r=0.359, P<0.01) and four dimensions of diabetes distress( r=0.177-0.354, P<0.01). Partially mediating effect of illness perception( B=0.216, 95% CI=0.112-0.372) was found in glycemic control and depression, the proportion of effect was 25.9%.The chain mediating effect ( B=0.086, 95% CI=0.042-0.149) of illness perception and diabetes distress was also found between glycemic control and depression, whose indirect effect size was 10.3%. Conclusion:Glycemic control is significantly related with depression.Illness perception and diabetes distress are partly mediating the effect between glycemic control and depression.

Boron neutron capture therapy(BNCT), a promising radiotherapy, belongs to precision treatment for cancers. BNCT can accurately kill cancer cells and protect normal cells at the same time relying on 10B compounds with high efficacy. The research about developing new 10B compounds is in progress, and novel and efficient 10B compounds are emerging, which greatly facilitate broadening the advantages and efficacy of BNCT. Considering the mixed rays generated from the BNCT process, its biological effects on tumor cells are relatively complex, and related studies are still lacking. The molecular mechanisms underlying BNCT need to be elucidated further. BNCT has been applied in the treatment of malignant brain tumors, head and neck cancers, and malignant melanoma with favorable curative effects. This review mainly focuses on the development of 10B compounds, biological mechanisms, potential advantages, and clinical applications.
