The rapid development and promotion of minimally invasive thoracic surgery represented by video-assisted thoracoscopy surgery has gradually replaced traditional thoracic surgery technique as the primary choice for the treatment of pulmonary nodules, including early lung cancer. With the clinical application of double-lumen bronchial catheters, the realization of one-lung ventilation technology not only provides a solid anesthesia foundation for the popularization of minimally invasive thoracic surgery, but also provides a guarantee for the rapid and smooth implementation of the operation. However, compared with single-lumen bronchial catheters, the diameter of the double-lumen bronchial catheter is thicker, and the tube body is hard and difficult to shape, which brings inconvenience to anesthesia intubation. The bronchial structure is different, and the incidence of dislocation during anesthesia intubation is also high. With the gradual clinical use of video double-lumen tube (VDLT), it has become a hot spot in thoracic surgery in recent years. This article reviews the application and research progress of VDLT in thoracic surgery.

Conventional therapies for hemophilia A (HA) are prophylactic or on-demand intravenous FVIII infusions. However, they are expensive and inconvenient to perform. Thus, better strategies for HA treatment must be developed. In this study, a recombinant FVIII cDNA encoding a human/rat hybrid FVIII with an enhanced procoagulant potential for adeno-associated virus (AAV)-delivered gene therapy was developed. Plasmids containing human FVIII heavy chain (hHC), human light chain (hLC), and rat light chain (rLC) were transfected into cells and hydrodynamically injected into HA mice. Purified AAV viruses were intravenously injected into HA mice at two doses. Results showed that the hHC + rLC protein had a higher activity than the hHC + hLC protein at comparable expression levels. The specific activity of hHC + rLC was about 4- to 8-fold higher than that of their counterparts. Hydrodynamic injection experiments obtained consistent results. Notably, the HA mice undergoing the AAV-delivered hHC + rLC treatment exhibited a visibly higher activity than those treated with hHC + hLC, and the therapeutic effects lasted for up to 40 weeks. In conclusion, the application of the hybrid FVIII (hHC + rLC) via an AAV-delivered gene therapy substantially improved the hemorrhagic diathesis of the HA mice. These data might be of help to the development of optimized FVIII expression cassette for HA gene therapy.

In recent years, many scholars have explored the clinical application value of a number of peripheral hematology indexes in tumor patients. The significant correlation of neutrophil to lymphocyte ratio and platelet to lymphocyte ratio with the prognosis in various tumors has also been confirmed. At present, more peripheral blood indexes have been gradually applied to the evaluation of the prognosis in patients with malignant tumors. Small cell lung cancer (SCLC) is a type of highly malignant tumor and most patients are in advanced stage at the time of diagnosis. The evaluation value of tumor stage for survival is extremely limited. Therefore, this review intends to explain the relationship between various peripheral hematology indexes and the prognosis of SCLC patients, so as to provide some academic evidence for the clinical assessment of the survival of SCLC patients and formulation of appropriate treatment strategy, which may contribute to the improvement of the prognosis.

Objective:This study aimed to investigate the effect of short-term antipsychotic medication treatment of patients with schizophrenia on the effect of the thalamocortical resting-state functional connectivity.Methods:83 first-episode drug-na?ve schizophrenia patients and 117 matched healthy controls participated in the present study. The study collected resting-state fMRI data before and after the patients received short-term antipsychotics to assess the changes in the thalamocortical circuits and clinical symptoms. The directional interactions between the thalamus and other brain regions were investigated using a standard seed-based whole-brain correlation by choosing the bilateral thalamus as the seeds. Spearman′s correlation analysis was carried out between the change of abnormal functional connectivity and improved clinical symptoms in patients.Results:Compared with the healthy controls, schizophrenia patients showed decreased thalamic-prefrontal functional connectivity (including the middle frontal cortex, inferior frontal cortex, middle cingulate cortex, posterior cingulate cortex, and inferior parietal lobe, all P<0.05, FDR corrected) and increased thalamic-sensorimotor functional connectivity(including the precentral gyrus, superior temporal cortex, middle temporal cortex, inferior temporal cortex, parahippocampus, and middle occipital cortex, all P<0.05, FDR corrected)at baseline. After short-term antipsychotic treatment, the thalamic-prefrontal hypo-connectivity was significantly enhanced, and the thalamic-sensorimotor hyper-connectivity was significantly decreased. Furthermore, the changes of abnormal functional connectivity were correlated significantly with the PANSS total score changes improvement ( r=0.435, P=0.014; r=0.394, P=0.028,uncorrected). Conclusions:The present study replicates previous findings that the abnormalities of thalamocortical circuits in schizophrenia are characterized by thalamic-prefrontal hypoconnectivity and thalamic-sensorimotor hyperconnectivity. Moreover, short-term antipsychotic treatment partly improves thalamocortical abnormalities, which further relates to clinical symptom relief; Restoring of abnormal thalamocortical circuits plays an important role in the early treatment of schizophrenia.

OBJECTIVE：To study the improvement effects of paeon iflorin（PF）on myocardial injury in type 2 diabetes mellitus（T2DM）model rats and its mechanism. METHODS ：The experiment was set up in the normal group ，model group ， positive control group （metformin 90 mg/kg），PF high-dose ，medium-dose and low-dose groups （90，60，30 mg/kg），with 8 rats in each group. Except for normal group ，other groups were given high-glucose and high-fat diet and intraperitoneal injection of streptozotocin （30 mg/kg） to induce T 2DM model. After modeling ， administration groups were given relevant medicine intragastrically，normal group and model group were given constant volume of normal saline intragastrically ，once a day ，for consecutive 4 weeks. The body weight ，fasting blood glucose and oral glucose tolerance were measured ；serum levels of glycosylated serum protein （GSP），total cholesterol （TC），triacylglycerol（TG），glutathione peroxidase （GSH-Px），superoxide dismutase（SOD），malondialdehyde（MDA），creatine kinase isoenzyme-MB （CK-MB） and troponin Ⅰ （cTn Ⅰ） were determined. The pathomorphological changes of myocardium were observed. The apoptosis index of rat cardiomyocytes was （ detected. The protein expression of B-cell lymphoma 2 （Bcl-2），Bcl-2 related X protein （Bax）and caspase- 3 in rat myocardium were detected by immunohistochemistry and Western blot. RE SULTS：Compared with normal group ，the body weight ，serum levels of GSH-Px and SOD ，protein expression of Bcl- 2 in myocardium were decreased significantly in model group（P＜0.01）；while fasting blood glucose ，area under blood glucose curve ，serum levels of biochemical indexes （GSP，TC， TG，MDA，CK-MB，cTnⅠ），cardiomyocyte apoptosis index ，protein expression of Bax and caspase- 3 in myocardium were increased significantly （P＜0.05 or P＜0.01）. The arrangement of myocardium was relatively irregular ，and some muscle fibers were broken. Compared with model group ，except for body weight ，serum levels of SOD and MDA ，the protein expression of Bax in myocardium in PF low-dose group ， above indexes of PF groups were reversed significantly （P＜0.05 or P＜0.01）. CONCLUSIONS：PF can regulate glycolipid metabolism ，enhance antioxidant ability ，inhibit cardiomyocyte apoptosis and improve myocardial injury in T 2DM model rats ；the mechanism may be associated with increasing the protein expression of Bcl- 2 and down-regulating the protein expression of Bax and caspase- 3 in myocardium.

Tumor microenvironment (TME) is a dynamic network distributed around tumor cells. Cancer-associated fibroblasts (CAFs), as an important component of the TME, are not only closely related to normal fibroblasts, but also can secrete a variety of substances to participate in the regulation of the TME. Exosomes, one of the substances from CAFs, can promote the formation and development of lung cancer, including promoting the formation of TME, increasing pulmonary tumor cell invasion and metastasis, mediating pulmonary tumor immunosuppression and participating in radiotherapy and chemotherapy resistance. This article reviews the current research status and progress of cancer associated fibroblasts-derived exosomes in lung cancer.

The good results of enhanced recovery after surgery (ERAS) combined with minimally invasive surgery are reflected in reducing the incidence of perioperative complications and shortening the length of hospitalization (LOS). It has been widely used in surgical fields of different specialties. The implementation of the day surgery mode can shorten the waiting time for patients and reduce the financial burden. Especially in thoracic surgery, the shorter the waiting time in the hospital, the more beneficial for the patient's physical and psychological recovery. With the widespread implementation of minimally invasive technology and accelerated rehabilitation procedures, the application of ERAS in thoracic surgery has made it possible for some thoracic surgery to be completed in the day surgery. This article summarizes the current application of ERAS in the field of thoracic surgery and the development prospects of day surgery models in China.

The cell cycle-related transcription factor E2F1 is a member of the cell cycle-related transcription factor E2F family, mainly involved in various cell processes including cell cycle progression, DNA repair, DNA replication, cell differentiation, proliferation, and apoptosis. E2F1 is highly expressed in a variety of tumor tissues and cells, and it plays a role as a cancer-promoting gene. The up-regulation of E2F1 expression is closely related to the occurrence, development, metastasis and prognosis of tumors. Therefore, E2F1 is expected to become a new target for cancer treatment. This article reviews the latest research progress of E2F1 in current common tumors.
