BACKGROUND:The objective of this retrospective hospital-based study was to describe the epidemiological features of traumatic spinal cord injury(TSCI)in the intensive care unit(ICU)and assess the incidence and possible risk factors for venous thromboembolism(VTE)following TSCI. METHODS:We retrospectively reviewed the medical records of 370 patients with TSCI who were admitted between January 2018 and March 2023.The following parameters were collected:age,sex,body mass index,occupation,underlying diseases,smoking history,education level,etiology of injury,injury segments,American Spinal Injury Association(ASIA)Impairment Scale score,severity of injury,injury severity score(ISS),VTE risk score(Caprini score),treatment,VTE prophylaxis,ICU length of stay,length of hospital stay,concomitant injuries,and complications.Descriptive statistics were used to summarize the demographic and clinical characteristics of the study participants.Logistic regression analysis was used to determine the risk factors for VTE. RESULTS:The mean age of patients with TSCI was 55.5±13.4 years,with a male-to-female ratio of 6.5:1.The leading cause of TSCI was falls from height(46.5%),followed by traffic accidents(36.5%).The cervical spinal cord was the most affected segment,followed by the thoracolumbar region.Among all the patients,362(97.8%)had concomitant injuries.Complications were observed in 255 patients(68.9%)during hospitalization.The incidence rate of VTE was 25.1%.Logistic regression analysis revealed that age(OR=1.721,95%CI:1.207-2.454,P=0.003),mechanical ventilation(OR=3.427,95%CI:1.873-6.271,P<0.001),and non-use of chemical prophylaxis(OR=2.986,95%CI:1.749-5.099,P<0.001)were risk factors for VTE. CONCLUSION:Falls from height and traffic accidents were the main causes of TSCIs in the ICU,especially for male patients with cervical spinal cord injuries.VTE is a frequent complication in patients with TSCI in the ICU.Age,mechanical ventilation,and non-use of chemical prophylaxis were found to be independent risk factors for VTE following TSCI.

OBJECTIVE To investigate the mechanisms by which Pinggan Yishen Decoction(PGYSD)contributes to alleviating target organ damage in spontaneously hypertensive rats.METHODS The chemical components of PGYSD were determined by ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF/MS)and were analyzed by target a-nalysis and functional enrichment combined with network pharmacology methods to predict the potential mechanism of PGYSD in trea-ting hypertension and its target organ damage.Spontaneously hypertensive rats were randomly divided into the model group,low-dose PGYSD group(2 g·kg-1),high-dose PGYSD group(5 g·kg-1),and valsartan group(7.2 mg·kg-1),with 6 rats in each group.Wistar-Kyoto rats were used as the control group,and the control group and the model group were gavaged with normal saline for 8 consecutive weeks.HE and Masson staining were used to observe the pathological damage and fibrosis degree of rat heart and tho-racic aorta.Immunohistochemical staining and Western blot were used to detect the expression level of EGFR in the heart,liver and kidney of rats.Immunofluorescence staining was used to detect the co-localization of EGFR and EEA1 in the heart,liver and kidney of rats.RESULTS Twenty-six components of PGYSD were detected by UPLC-Q-TOF/MS.Network pharmacology revealed that EG-FR,PIK3R1 and EP300 may be key therapeutic targets of action of PGYSD for the treatment of hypertension and its target organ dam-age,and that the treatment of hypertension and its target organ damage by PGYSD may be closely related to EGFR tyrosine kinase in-hibitor resistance,lipids and atherosclerosis and HIF-1 signaling pathway.The high-dose group of PGYSD significantly reduced sys-tolic blood pressure and mean blood pressure in rats(P<0.05,P<0.01),attenuated pathological damage and fibrosis in the heart and thoracic aorta(P<0.01,P<0.001),significantly reduced the expression level of EGFR in the liver and kidney of rats(P<0.01),and treated fibrosis in liver and kidney,reduced the co-localization of EGFR and EEA1 in the kidney of rats(P<0.001),attenuated fibro-sis in kidney.CONCLUSION The paper integrates UPLC-Q-TOF/MS,network pharmacology and spontaneously hypertensive rat model and preliminarily explores the effect mechanism of PGYSD in the treatment of hypertension and its target organ damage,provi-ding a scientific basis for further mechanism research and clinical application of PGYSD in the treatment of hypertension.

Background and objective Pembrolizumab(PEM)has been shown to be effective in clinical trials for the treatment of advanced non-small cell lung cancer(NSCLC),but clinical trials were based on cohorts of patients selected on specific criteria,and whether the findings are consistent with real-world patients is debatable.The aim of this study is to evaluate the efficacy and safety of PEM in the treatment of advanced NSCLC based on real-world data.Methods A retro-spective collection of real-world data from patients with advanced NSCLC receiving PEM was conducted.Propensity score matching was used to eliminate inter-group differences and assess the efficacy and safety of PEM compared to chemotherapy.Results Among 450 matched patients,the incidence rates of any-grade adverse events were 79.87％in the PEM group and86.71％inthe chemotherapy group,while the incidence rates of grade＞3 adverse events were 4.03％and 7.31％,respectively.The objective response rates were 48.63％for PEM and 36.00％for chemotherapy(P=0.011).The median progression-free survival was 15.5 months for PEM and 8.8 months for chemotherapy(P＜0.001),and the median overall survival was not reached for PEM and 26.2 months for chemotherapy(P＜0.001).Conclusion PEM treatment for advanced NSCLC demonstrates favorable survival outcomes and acceptable safety in real-world clinical practice.
