RESUMEN
Lung cancer associated with cystic airspaces (LCCA) is a type of lung cancer characterized by the presence of cystic cavities in or around the tumor on imaging. Due to its high potential for misdiagnosis or underdiagnosis, the prognosis of LCCA patients is poor, necessitating further large-scale clinical studies to elucidate its characteristics. Currently, four imaging classification systems exist, and there has been a progressive increase in attention towards LCCA, particularly with regard to the study of its imaging features. The results indicate a correlation between the pathological features and imaging findings of LCCA; however, research on driver gene mutations and molecular subtyping associated with lung cancer remains insufficient. Due to the challenges associated with early diagnosis and the poorer prognosis compared to general types of lung cancer, this paper comprehensively reviews the research progress on LCCA, including its definition, etiology, pathogenesis, imaging features, histological and pathological features, treatment, and prognosis, aiming to serve as a valuable resource for clinical decision-making. .

Escherichia coli is a highly adaptable opportunistic pathogen bacterium that can form biofilms on the surface of implants and generates persistent cells,leading to life-threatening infections that are difficult to treat with antibiotics alone.Therefore,there is a need for an effective E.coli biofilm inhibitor to combat this public health threat.Indole is a novel quorum-sensing signaling molecule of E.coli discovered in recent years,which is of great significance in regulating bacterial growth and biofilm formation,and is a potential target for future research on new anti-biofilm preparations.This article reviews the research progress on the formation of Escherichia coli biofilms,the microbial metabolism of indole and its regulation of Escherichia coli biofilm formation,in order to provide information for clinical treatment and drug development.
RESUMEN
Objective To explore the effect of team-based tutorial system to nursing student in the order cultivation Pattern.Methods This study used the convenience sampling method.109 students were choosed from orientation training classes that 2012 and 2013 grade as the research subjects.The 59 students from 2013 grade as the test group,implement team-based tutorial system to them in the fourth semester.The 50 students from 2012 grade that had been implemented general management as the control group,then compare the fourth semester final grade,classes atmosphere,the evaluation of patients and clinical teachers over the same period.Results The test group and control group students' scores of their fourth semester final grade,classes atmosphere,the evaluation of clinical teachers and patients were (92.39±2.39),(3.45±0.64),(95.33±2.01),(94.75±2.38) points and (90.91±2.62),(3.14±0.63),(91.00±1.82),(90.63±2.34) points.There was difference between them,and the difference was statistically significant (t=-7.82 ~ 3.06,P < 0.05).Conclusions The implementation of team-based tutorial system to nursing student in the order cultivation pattern can improve students' academic performance,improve their class atmosphere and their communication skills so that patients get good evaluation of patients and clinical teachers.
