To investigate the association between sleep-related phenotypes and the risk of malignancy in pulmonary nodules, and to provide complementary evidence from a general population cohort and genetic analyses.

Objective The finite element pelvis model with detailed anatomical structures which meets the Chinese human 95th percentile characteristics is developed,and the influence of cortical bone modeling method on the biomechanical response of the real pelvis is explored.Methods Based on the pelvic medical images of a 95th percentile male volunteer,two finite element pelvis models with real hip bone cortical bone thickness(REA-M)and 2 mm uniform cortical bone thickness(CON-M)dominated by hexahedral elements were constructed.Using the simulation method to reconstruct the loading conditions of cadaver experiments,the validation of models was verified by comparing the cadaver experimental results and simulation results,and biomechanical response differences of two models under different working conditions were discussed.Results The simulation data showed that there was a strong correlation between the overall biomechanical responses of two pelvic models and the cadaver experiment,and the mechanical response difference between two models was mostly within 8％,and the correlation score difference between two models was smaller than 2％.Conclusions The validation of two pelvic models established in this study is verified by rebuilding multiple simulation experiments.Although the biomechanical responses of CON-M and REA-M models were different,the difference was small.From the perspective of model simplification,the CON-M model can be used to study the biomechanical response of the pelvis.

Carbon ion radiotherapy(CIRT)is an advanced radiotherapy method with unique physical and biological properties.It increases the dose to the tumor target area while providing better protection to normal tissues.CIRT can be used for hypoxic tumors resistant to photon radiotherapy.It also has the potential superiority of inducing immune responses and can produce the"abscopal effect"when com-bined with different immunotherapies.Radioimmunotherapy can not only ablate tumors at the irradiated site but also partially control dis-tant metastases at the unirradiated site.However,the underlying mechanism has not been fully elucidated.Due to the protection of the tu-mor microenvironment,tumors can sometimes be difficult to completely clear through CIRT-mediated anti-tumor immunity;this can also in-dicate functional limitations of some immune organs after CIRT.Therefore,this study reviewed the impact of CIRT on both innate and adapt-ive immune responses.It also examined the relationship between different radiation doses/fractions and immune protein expression,as well as compared the differences in imaging techniques between carbon ion radiotherapy and traditional radiotherapy.We have also proposed future directions to enhance the superiority of CIRT.This study aimed to provide a strong theoretical basis for improving the efficacy of CIRT and its combination therapy,ultimately benefiting more patients with cancer.

Progress in the treatment of gastric cancer(GC)is a major concern because GC is a common cancer worldwide.Recently,by studying the molecular mechanisms of GC,researchers learned that GC progression involved a series of changes at the molecular lev-el,including the activation of signaling pathways,abnormal expression and mutation of genes,and response to related targeted drugs used in clinics.However,many targeted drugs produce resistance in a short period of time because of complicated cellular,microenvi-ronmental,and genetic instabilities.Therefore,it is important to find new targets against GC.In this review,we present the current re-search status and progress with respect to GC targets.
