Current status and future prospects for the use of tertiary lymphatic structures in the diagnosis and treatment of lung cancer / 中华胸心血管外科杂志

Lung cancer is one of the malignant tumors with the highest incidence and mortality rate worldwide and has a poor prognosis. With the popularization of thin layer CT, more and more early lung cancers are being detected. In recent years, thoracoscopic technology and robotic surgery technology have been innovated, and multiple adjuvant therapies such as chemotherapy, targeted therapy and immunotherapy have progressed rapidly, providing lung cancer patients with multiple treatment options. However, the prognosis of lung cancer patients has not been significantly improved, which is related to the overall poor prognosis of lung cancer patients on the one hand, and the urgent need to find effective predictive markers for patients' prognosis, to accurately screen patients, and to carry out targeted treatment in order to improve patients' prognosis on the other hand. In this paper, we review the progress of tertiary lymphoid structures (TLSs) in lung cancer and discuss the prognostic predictive value of TLSs in lung cancer and their feasibility as biomarkers for adjuvant therapy.

Changes of serum brain derived neurotrophic factor and heat shock protein 70 and their significance in children with complicated febrile convulsions / 中华神经医学杂志

Objective To investigate the serum levels of brain derived neurotrophic factor (BDNF) and heat shock protein 70 (HSP70),and evaluate their clinical significance in brain injury of children with complicated febrile convulsions (CFC).Methods Forty-three patients with CFC,41 children with simple febrile convulsions and 36 healthy controls were recruited in this study; their serum levels of BDNF and HSP70 were detected by enzyme linked immunosorbent assay (ELISA); correlation between levels of BDNF and HSP70 and both time of twitch duration and twitch frequency were analyzed.Results The mean serum concentrations of BDNF (4.96±1.21 ng/mL) and HSP70 (2.86± 0.93 ng/mL) in patients of CFC group were significantly higher than those in patients of simple febrile convulsions and healthy controls (P＜0.05); while no significant difference was noted between patients of simple febrile convulsions and healthy controls (P＞0.05).These changes were closely related to the duration time and frequency of convulsions(r=0.553,P=0.015; r=0.587,P=0.012; r=0.526,P=0.024; r=0.562,P=0.018).Conclusions It is sure that some brain injury exists in children with CFC; BDNF and HSP-70 might be one of the molecular mechanisms for the brain injury and protective effect.
