Lung cancer is the most common malignant tumor worldwide, ranking first in both incidence and mortality rates. According to the latest statistics from the International Agency for Research on Cancer (IARC), approximately 2.5 million new cases and around 1.8 million deaths from lung cancer occurred in 2022, placing a tremendous burden on global healthcare systems. The high mortality rate of lung cancer is closely linked to its subtle early symptoms, which often lead to diagnosis at advanced stages. This not only complicates treatment but also results in substantial economic losses. Current treatment options for lung cancer include surgery, radiotherapy, chemotherapy, targeted drug therapy, and immunotherapy. Among these, immunotherapy has emerged as the most groundbreaking advancement in recent years, owing to its unique antitumor mechanisms and impressive clinical benefits. Unlike traditional therapies such as radiotherapy and chemotherapy, immunotherapy activates or enhances the patient’s immune system to recognize and eliminate tumor cells. It offers advantages such as more durable therapeutic effects and relatively fewer toxic side effects. The main approaches to lung cancer immunotherapy include immune checkpoint inhibitors, tumor-specific antigen-targeted therapies, adoptive cell therapies, cancer vaccines, and oncolytic virus therapies. Among these, immune checkpoint inhibitors and tumor-specific antigen-targeted therapies have received approval from the U.S. Food and Drug Administration (FDA) for clinical use in lung cancer, significantly improving outcomes for patients with advanced non-small cell lung cancer. Although other immunotherapy strategies are still in clinical trials, they show great potential in improving treatment precision and efficacy. This article systematically reviews the latest research progress in lung cancer immunotherapy, including the development of novel immune checkpoint molecules, optimization of treatment strategies, identification of predictive biomarkers, and findings from recent clinical trials. It also discusses the current challenges in the field and outlines future directions, such as the development of next-generation immunotherapeutic agents, exploration of more effective combination regimens, and the establishment of precise efficacy prediction systems. The aim is to provide a valuable reference for the continued advancement of lung cancer immunotherapy.

Objective To understand the nursing practice of prone position ventilation for patients with moderate to severe acute respiratory distress syndrome(ARDS)in intensive care unit(ICU)in Shandong province,so as to provide basis for standardizing the nursing practice process of prone position ventilation and carrying out training for hospitals.Methods A self-made questionnaire was used,and convenience sampling was adopted.From September 15th to November 5th,2023,ICU nurses were selected from various hospital levels in Shandong province to investigate the obstructive factors of prone ventilation implementation,the weak links in nursing practice and status,and the occurrence of complications.Results A total of 1 188 questionnaires were collected,of which 991 were valid.92.8%(920/991)of nurses had performed prone position ventilation.The biggest obstacle to the implementation of prone position ventilation was the complexity of patient treatments and multiple devices involved[74.6%(686/920)].Regarding the status of training,90.5%(897/991)of nurses had received training on prone position ventilation and 77.0%(763/991)of nurses felt that training was needed.As for pre-operation assessment,more than 80.0%of nurses evaluated patients'vital signs,airway and secretions and so on,among which the evaluation awareness of analgesia was the worst[81.6%(751/920)].As for the main points of implementation,only 14.0%(129/920)of nurses chose the opposite side of the most important pipeline as the turning direction;48.6%(447/920)of nurses chose the anti-Trendelenburg position;36.3%(334/920)of nurses chose to ventilate≥12 hours.Facial edema[81.7%(752/920)],skin pressure injury[78.9%(726/920)]and eye complication[75.8%(697/920)]were the top 3 most frequent complications.Conclusions ICU nurses'prone position ventilation practices were generally line with the nursing team standard for prone position of adult mechanically ventilated patients and the best evidence recommendation,and needs to be further standardized in aspects of turning direction,position management,ventilation duration,and enteral nutrition management.It is recommended that nursing managers at all levels of hospitals further improve the quality of nursing practice of prone position ventilation according to relevant evidence-based evidence and the actual situation of hospitals.

Aim To investigate the effect of triptolide(TP)on corticosterone(CORT)-induced depression-like behaviors in mice and explore the antidepressant mechanism of TP based on the CREB/BDNF/TrkB sig-naling pathway.Methods Sixty 8-week-old male C57BL/6J mice were randomly divided into five groups:control group,CORT group,TP groups of low and high doses(10,30 μg·kg-1),and fluoxetine(FLU)group(10 mg·kg-1).Except for the control group,the other groups received subcutaneous injec-tions of CORT for three consecutive weeks to establish the model of depression.During the last two weeks of modeling,normal saline,TP and FLU were adminis-tered via intraperitoneal injection respectively.After the administration,depression-like behaviors in mice were assessed using forced swimming test,tail suspen-sion test,and sucrose preference test.Biochemical methods were used to measure the levels of SOD and MDA in the hippocampus and prefrontal cortex(PFC).Cell apoptosis was detected by TUNEL meth-od.Immunohistochemistry,immunofluorescence,and Western blotting were employed to detect the expres-sion of apoptosis/autophagy-related proteins,synaptic structure markers,and proteins related to the CREB/BDNF/TrkB signaling pathway.Results TP signifi-cantly ameliorated CORT-induced depression-like be-haviors in mice,mainly manifested by reduced immo-bility time in the tail suspension test and forced swim-ming test,and increased sucrose preference rate.TP alleviated CORT-induced oxidative stress by increasing SOD levels and reducing MDA production in brain tis-sue.Additionally,TP also inhibited apoptosis and ex-cessive autophagy of neurons in the hippocampus and prefrontal cortex,maintained synaptic plasticity,and significantly upregulated the expression of p-CREB,BDNF,and TrkB.Conclusions TP exhibits potential antidepressant effect in mice by upregulating the CREB/BDNF/TrkB signaling pathway,reducing oxida-tive stress,inhibiting excessive neuronal apoptosis and autophagy,and improving synaptic plasticity.

AIM To investigate the clinical effects of Modified Banxia Xiexin Decoction combined with Lizhong Decoction on patients with type 2 diabetes mellitus due to Cold-heat Complex in the Middle Energizer.METHODS One hundred and sixty-eight patients were randomly assigned into control group(84 cases)for 12-week intervention of conventional treatment,and observation group(84 cases)for 12-week intervention of Modified Banxia Xiexin Decoction,Lizhong Decoction and conventional treatment.The changes in clinical effects,compliance rate of blood glucoses,discontinuation and reduction rate of hypoglycemic drugs,continuous glucose parameters(TIR,GVP,FPG-ARV,MAGE),FPG,2 hPG,HbA1c,FINS,HOMA-β,HOMA-IR,lnISI,intestinal flora metabolites(SCFAs,CA,DC A,CDCA,CA/CDCA),score for Cold-heat Complex in the Middle Energizer and incidence of adverse reactions were detected.RESULTS The observation group demonstrated higher marked improvement rate,total effective rate,compliance rate of blood glucoses and discontinuation and reduction rate of hypoglycemic drugs,than the control group(P＜0.05).After the treatment,the two groups displayed increased TIR,FINS,HOMA-β,lnISI,SCFAs,CDCA(P＜0.05),and decreased GVP,FPG-ARV,MAGE,FPG,2 hPG,HbA1c,HOMA-IR,CA,DC A,CA/CDCA,score for Cold-heat Complex in the Middle Energizer(P＜0.05),especially for the observation group(P＜0.05).No significant difference in incidence of adverse reactions was found between the two groups(P＞0.05).CONCLUSION For the patients with type 2 diabetes mellitus due to Cold-heat Complex in the Middle Energizer,Modified Banxia Xiexin Decoction combined with Lizhong Decoction can improve islet β cell function and insulin resistance,enhance insulin sensitivity index and compliance rate of blood glucoses,reduce blood glucose fluctuation and dosages of hypoglycemic drugs,regulate intestinal flora metabolites,and affect glucose metabolism.

This study was aimed at understanding the prevalence and drug resistance status of Salmonella of waterfowl ori-gin in the Guangdong region in the past decade,to guide prevention and control efforts.The drug-sensitive paper slide method was used to conduct drug susceptibility testing on 314 waterfowl-originating Salmonella strains isolated from 238 waterfowl farms in the Guangdong region from 2013 to 2023.The isolated Salmonella strains were most resistant to penicillin,amoxicil-lin,cefradine,and cefazolin in the β-lactam group;sulphadoxine dimethylpyrimidine in the sulphonamide group;and tetracy-cline in the tetracycline group.The resistance rates ranged from 73.57％to 89.49％.The highest sensitivity was observed to amikacin,gentamicin,and kanamycin in the aminoglycoside group,and norfloxacin in the quinolone group,with susceptibility rates all exceeding 50％.The 280 strains of Salmonella showed multi-drug resistance to six classes of antimicrobial drugs and high resistance(as much as 60.83％)to five drug classes.Correlation analysis revealed the highest correlations for florfenicol with gentamicin,and for amoxicillin with penicillin(r=0.650 for both),followed by gentamicin with kanamycin(r=0.620).Salmonella resistance in waterfowl in Guangdong Province was generally severe and showed a complex pattern of drug resist-ance.Detection of waterfowl pathogens should be strengthened to prevent the spread of drug-resistant bacteria and support ra-tional use of antibiotics.This work provides a reference for Salmonella prevention and control in waterfowl farms.

Objective To investigate the effect of salvianolic acid B(Sal B)on high glucose(HG)induced necrotic apoptosis of retinal pigment epithelial cells(RPE)by regulating the receptor-interacting protein kinase 1(RIP1)/RIP3/mixed lineage kinase domain like protein(MLKL)signaling pathway.Methods RPE cells ARPE-19 were used as the research object and separated into control(Con)group,HG group,L-Sal B group,M-Sal B group,H-Sal B group,pcDNA3.1-NC group,and pcDNA3.1-RIP1 group.The qRT-PCR method was applied to detect the expression of RIP1,RIP3,and MLKL in ARPE-19 cells in each group.CCK8 was applied to detect ARPE-19 cell survival rate.Flow cytometry was applied to detect cell apoptosis.DCFH-DA fluorescent probe was applied to detect reactive oxygen species(ROS)level.ELISA was applied to detect the expression of tumor necrosis factor-α(TNF-α),interleukin(IL-1β),and IL-6.Western blot was applied to detect the expression of RIP1,RIP3,and MLKL proteins.Results The cell survival rate was lower in the HG group than in the Con group(P<0.05).The cell apoptosis rate,the proportion of ROS-positive cells,TNF-α,IL-1β,IL-6,and the mRNA and protein expressions of RIP1,RIP3,and MLKL were higher in the HG group than in the Con group(P<0.05).The cell survival rates were higher,while the cell apoptosis rates,the proportion of ROS-positive cells,TNF-α,IL-1β,IL-6,and the mRNA and protein expressions of RIP1,RIP3,and MLKL were lower in the L-Sal B,M-Sal B,and H-Sal B groups than in the HG group(P<0.05).The cell survival rates increased successively(P<0.05),while the cell apoptosis rates,the proportion of ROS-positive cells,TNF-α,IL-1β,IL-6,and the mRNA and protein expressions of RIP1,RIP3,and MLKL decreased successively in the L-Sal B,M-Sal B,and H-Sal B groups(P<0.05).The cell survival rate was lower(P<0.05),while the cell apoptosis rate,the proportion of ROS-positive cells,TNF-α,IL-1β,IL-6,and the mRNA and protein expressions of RIP1,RIP3,and MLKL were higher in the pcDNA3.1-RIP1 group than in the H-Sal B and pcDNA3.1-NC groups(P<0.05).Conclusions Sal B may inhibit the necrotic apoptosis of RPE cells induced by HG by suppressing the RIP1/RIP3/MLKL signaling pathway.
