Programmed cell death 1 (PD-1) inhibitor therapy for lung adenocarcinoma may induce rare but severe hematologic adverse events, including severe anemia. Although glucocorticoids are recommended for managing immune-related adverse events, therapeutic experience with PD-1 inhibitor-induced severe anemia remains limited, and its efficacy and safety have not been fully validated. This article reports a case of advanced lung adenocarcinoma in which severe anemia developed following combination therapy with chemotherapy and PD-1 inhibitor. After comprehensive evaluation, the patient was diagnosed with anemia of inflammation (AI) and achieved significant hemoglobin recovery following high-dose glucocorticoid treatment. These findings may provide new insights into the recognition and management of this rare hematologic toxicity in clinical practice.

Objective To discuss the application of multi-parameters of coronary CT angiography(CTA)in diagnosing coronary heart disease(CHD)and predicting major adverse cardiovascular events(MACE)after percutaneous coronary intervention(PCI).Methods A total of 350 patients with CHD,who received PCI at the Affiliated Beijing Rehabilitation Hospital of Capital Medical University of China from January 2021 to January 2024,were enrolled in this study as observation group.Other 180 patients with suspected CHD,who underwent coronary CTA and coronary angiography(CAG)to exclude coronary artery lesion in the same period as in the observation group,were collected and used as control group.According to whether MACE occurred or not within 6 months after PCI,the patients of observation group were further divided into MACE group and non-MACE group.The CTA parameters,including total plaque volume(TPV),plaque burden(PB),remodeling index(RI),fat attenuation index(FAI)around coronary artery,spot calcification and napkin-ring sign,were compared between the observation group and the control group as well as between MACE group and non-MACE group.Logistic regression analysis was used to analyze the independent factors influencing the occurrence of MACE after PCI.Area under receiver operating characteristic curve(AUC)was adopted to assess the value of each parameter in predicting the occurrence of MACE within 6 months after PCI.Results The TPV,PB,RI,FAI,and the detection rate of spot calcification and napkin-ring sign in the observation group were significantly higher than those in the control group(P＜0.05).Of the 350 patients in the observation group,54(15.43％)developed MACE within 6 months after PCI,including cardiac death(n=5,1.43％),non-fatal myocardial infarction(n=22,6.29％),target vessel reconstruction due to in-stent restenosis(n=15,4.29％),and hospitalization due to heart failure(n=12,3.43％),all the 54 patients were classified in MACE group.The non-MACE group had 296 patients.The TPV,PB,RI,FAI,and the detection rate of napkin-ring sign in MACE group were higher than those in non-MACE group(P＜0.05).Logistic multivariate analysis showed that TPV,PB and FAI were the independent factors influencing the occurrence of MACE in CHD patients after PCI(P＜0.05).ROC curve analysis indicated that in predicting the occurrence of MACE within 6 months after PCI the sensitivity of TPV,PB and FAI were 65.40％,76.90％and 76.90％respectively,and the specificity of TPV,PB and FAI were 63.80％,72.50％and 73.80％respectively.The sensitivity and specificity of the combined detection were 96.20％and 71.80％respectively,with an AUC of 0.896.Conclusion Multi-parameters of coronary CT A have important application value in diagnosing CHD and in predicting the occurrence of MACE after PCI.The combined detection of TPV,PB and FAI can provide important reference for making clinical decision.

Objective To evaluate the efficacy and safety of rabbit anti-human thymocyte immuneglobulin(rATG)induction therapy in kidney transplant recipients from donation after cardiac death in China.Methods This was a prospective,multicenter,single-arm and interventional study conducted in China(NCT03099122).Adult patients who underwent kidney transplantation from donation after cardiac death and received rATG induction therapy(cumulative dose of 5 mg/kg)were included.Univariate and multivariate logistic regression analyses were used to identify factors associated with acute rejection(AR),delayed graft function(DGF),graft failure and patient death.The occurrence of adverse events was also analyzed.Results A total of 115 adult patients were enrolled in the study,of whom 107 were evaluable for efficacy.The incidence of biopsy-proven acute rejection(BPAR)and acute rejection(AR)was 2.8%(95%confidence interval 0.6%-8.0%)and 4.7%(95%confidence interval 1.5%-10.6%),respectively.The incidence of delayed graft function(DGF)was 13.1%(95%confidence interval 7.3%-21.0%).Graft and patient survival rates were 97.2%(95%confidence interval 92.0%-99.4%)and 99.1%(95%confidence interval 94.9%-100%),respectively.Multivariate logistic regression analysis showed that donor serum creatinine and recipient panel reactive antibodies were risk factors for DGF(both P<0.05).Common treatment-emergent adverse events(incidence>5%)included anemia(8.7%),infectious pneumonia(8.7%),and urinary tract infection(8.7%).Conclusions Standard-dose rATG induction therapy demonstrates low incidences of BPAR,AR,and DGF,and good safety in kidney transplant recipients from donation after cardiac death in China.

Objective:To evaluate the therapeutic value of radiotherapy in combined immunotherapy and chemotherapy as first-line treatment for patients with oligometastatic non-small cell lung cancer (NSCLC).Methods:A retrospective analysis was conducted on data from 195 NSCLC patients who lacked epidermal growth factor receptor (EGFR) or anaplastic lymphoma kinase (ALK) mutations and were treated at the Anyang Tumor Hospital and the Fourth Hospital of Hebei Medical University from January 2019 to December 2021. These patients consisted of 166 male and 29 female cases, aged from 28 to 85 years, with an average age of (61.4 ± 9.3) years. These patients were divided into two groups, with each group receiving the radiotherapy and combined immunotherapy and chemotherapy (the radiotherapy and combination group, n = 60) and combined immunotherapy and chemotherapy only (the combination group, n = 135). Then, propensity score matching (PSM) was performed to analyze the differences in prognosis between both groups before and after PSM, as well as the short-term efficacy and adverse reactions after PSM. Results:For the 195 NSCLC patients, the median follow-up time was 31.8 months, with median overall survival (OS) and median progression-free survival (PFS) recorded at 23.8 months and 9.2 months, respectively. The radiotherapy and combination group exhibited enhanced 1-, 2-, and 3-year survival rates of 78.5%, 55.9%, and 45.1%, respectively, significantly higher than the combination group (48.3%, 35.6%, and 26.6%, respectively, χ2 = 14.65, P < 0.001). Similarly, the radiotherapy and combination group displayed 1-, 2-, and 3-year PFS rates of 51.9%, 29.5%, and 22.7%, respectively, exceeding those of the combination group (30.0%, 24.5%, and 16.9%, respectively, χ2=6.09, P=0.014). After PSM, the radiotherapy and combination group manifested an objective response rate (ORR) of 60.0% (33/55) and a disease control rate (DCR) of 89.1% (49/55), which were 16.4% (9/55) and 56.4% (31/55), respectively for the combination group. These results suggested that the radiotherapy and combination group demonstrated significantly higher ORR and DCR ( χ2 = 22.18, 14.85, P<0.001). After PSM, the radiotherapy and combination group yielded 1-, 2-, and 3-year survival rates of 70.9%, 52.3%, and 41.9%, respectively, significantly than the combination group (43.6%, 29.8%, and 27.1%, respectively, χ2=8.95, P=0.003). The radiotherapy and combination group exhibited 1-, 2-, and 3-year PFS rates of 47.3%, 27.3%, and 18.7%, respectively, significantly higher than the combination group (23.6%, 17.6%, and 15.4%, respectively, χ2 = 6.71, P = 0.010). Multivariate Cox regression analysis revealed that independent factors affecting OS included clinical stage, treatment regimen, number of immunotherapy cycles, and treatment efficacy ( HR = 1.88, 2.11, 0.23, 1.79, P < 0.05). Similarly, independent factors affecting PFS consisted of treatment regimen, number of immunotherapy cycles, and treatment efficacy ( HR = 1.62, 0.37, 3.42, P <0.05). There were no statistical differences in the incidence of grade ≥ 2 bone marrow suppression (18.2% vs. 12.7%) and grade ≥ 2 pneumonia (21.8% vs. 14.5%) between both groups ( P>0.05). Conclusions:Introducing radiotherapy into combined immunotherapy and chemotherapy as first-line treatment for oligometastatic NSCLC can optimize both local and systemic disease control and significantly improve patient prognosis without increasing treatment-related adverse reactions.

The human body's structure and function are complex,encompassing five viscera,six bowels,as well as differences in qi,blood,yin,and yang.However,the fundamental life activity primarily relies on the body's yang.Physiologically,when the body has sufficient yang and smooth blood circulation without stagnation,the five organs are nourished,ensuring their proper function.Conversely,pathologically,the deficiency of yang caused by cold injury leads to blood stagnation and prolonged stasis,resulting in inadequate nourishment of the five viscera and subsequent dysfunction.Depression is a condition that can be triggered by cold condensation and blood stasis.Acupuncture treatment follows the principle of warming yang and activating blood circulation.Key acupuncture points such as Baihui(GV20),Dazhui(GV14),Zhiyang(GV9),Mingmen(GV4),Guanyuan(CV4),and Zusanli(ST36)are used to warm yang and replenish qi,while Xuehai(SP10),Weizhong(BL40),and Sanyinjiao(SP6)are utilized to activate blood circulation and open up the veins.Additionally,supplementary points like Danzhong(CV17),Zhongwan(CV12),Qihai(CV6),Hegu(LI4),and Taichong(LR3)are employed to regulate qi and alleviate stagnation,facilitating the smooth flow of qi and blood.This comprehensive approach addresses both the symptoms and the root cause,simultaneously addressing deficiencies and replenishing the body.It aims to restore deficient yang,resolve blood stasis,promote the full and calm flow of qi and blood,nourish the five viscera and restore their proper function,ultimately leading to the self-healing of depression.

ObjectiveTo observe the effect of gastrodin on the steroid regulatory element-binding protein 1c （SREBP1c） signaling pathway in high-fat high-cholesterol diet （HFHC）-induced mice and explore the mechanism of gastrodin in the treatment of non-alcoholic fatty liver disease （NAFLD）. MethodEight-week-old male C57BL/6J mice were used in vivo and divided into the following four groups， with six mice in each group： normal group， gastrodin group （50 mg·kg^-1）， model group， and model + gastrodin group （50 mg·kg^-1）. NAFLD model was established by feeding mice with HFHC for four weeks， and the mice were euthanized and the liver tissues were collected after four weeks. In vitro experiments were performed using Huh7 cells which were divided into five groups， and induced with free fatty acids （FFA， 200 μmol·L^-1， oleic acid-palmitic acid 2∶1） to establish an NAFLD cell model. After 24 h， different concentrations of gastrodin （0， 5， 10， 20， and 40 μmol·L^-1） were added to each group and cultured for another 24 h. Oil red O staining was used to detect lipid accumulation in mouse liver and Huh7 cells. Hematoxylin-eosin （HE） staining was used to observe pathological changes in liver tissue. Levels of serum total cholesterol （TC）， low-density lipoprotein cholesterol （LDL-C）， and triglycerides （TG） were measured using an automatic biochemical analyzer. Relevant assay kits were used to detect liver TC， TG， and FFA levels. Real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot were used to detect the expression of lipid synthesis-related proteins fatty acid synthase （FASN）， acetyl-CoA carboxylase 1 （ACC1）， and stearoyl-CoA desaturase 1 （SCD1）. ResultCompared with the normal group， the model group showed significantly increased serum TC， LDL-C， and TG levels （P<0.01）， liver TC， TG， and FFA levels （P<0.01）， increased lipid accumulation in Huh7 cells （P<0.01）， and significantly increased expression levels of lipid synthesis-related genes SREBP1c， FASN， ACC1， and SCD1 in mice and Huh7 cells （P<0.01）. Compared with the model group， after gastrodin treatment， the serum TC， LDL-C， and TG levels in mice significantly decreased （P<0.05， P<0.01）， the severity of fatty liver disease improved significantly， liver TC， TG， and FFA levels decreased significantly （P<0.05， P<0.01）， lipid accumulation in Huh7 cells decreased significantly （P<0.05， P<0.01）， the expression levels of lipid synthesis-related genes SREBP1c， FASN， ACC1， and SCD1 in mice and Huh7 cells decreased significantly （P<0.05， P<0.01）. ConclusionGastrodin can reduce hepatic lipid accumulation and blood lipid levels， improve HFHC-induced NAFLD， and its mechanism of action may be related to the regulation of the SREBP1c lipid synthesis-related signaling pathway.

OBJECTIVE To construct a clinical model of motion sickness(MS),provide a relatively objective diagnostic model for MS research,and provide a basis for further clinical intervention of the disease.METHODS A total of 60 subjects were included and divided into experimental group and control group according to the presence or absence of MS.The MS clinical model was established using SRM-IV rotating chair.Peripheral blood was collected before and after acceleration exposure,and the contents of adrenocorticotropic hormone(ACTH),growth hormone(GH),prolactin(PRL),follicle stimulating hormone(FSH),luteinizing hormone(LH),thyroid stimulating hormone(TRH)and gastrin-17(G-17),acetylcholine(ACH)and 5-hydroxytryptamine(5-HT)were detected,Graybiel scale was used to evaluate the severity of MS.The correlation between MS symptoms and signs and peripheral blood indexes was analyzed by multiple linear regression,and the diagnostic model was established.construct a clinical model of MS and a diagnostic model based on blood parameters,so as to provide a reliable clinical model and an objective diagnostic model for MS research,and to provide a basis for further clinical intervention of the disease.RESULTS After acceleration exposure,the Graybiel scores,ACH,5-HT,ACTH,GH and PRL levels in peripheral blood of the experimental group were higher than those before exposure,and were significantly different from those of the control group(P<0.001).There was no significant difference in FSH,LH,TRH and G-17 between the two groups before and after acceleration exposure(P>0.05).Multi-index combined diagnostic model:Graybiel scores=-9.32+0.131×ACTH+0.055×ACH+0.041×5-HT.CONCLUSION The levels of ACH,5-HT,ACTH,GH and PRL increased during the onset of MS.The multi-index combined diagnosis model can provide a certain basis for the objective diagnosis of MS in clinical practice.

OBJECTIVE To identify key factors involved in the regulation of hypoxia-induced inflammation-related signaling pathways using a combination of bioinformatics methods and experiments. METHODS A cellular model of hypoxia-induced hippocampal neuronal damage was prepared by treating mouse hippocampal neuronal HT22 cells with CoCl2. The cells were then collected for transcriptome sequencing. Based on the sequencing results,key molecules were identified using differential analysis,gene ontology(GO) function and Kyoto Encyclopedia of Genomes(KEGG) pathway analysis,and protein-protein interaction network(PPI) analysis. The effects of key molecules on cells were investigated. RESULTS Differential analysis revealed a total of 8975 differential genes,which were subjected to GO and KEGG analysis. KEGG analysis revealed that these genes were involved in signaling pathways such as pancreatic cancer,EGFR tyrosine kinase inhibitor resistance,animal mitosis,base excision repair,and chronic myeloid leukemia. PPI networks were constructed for genes enriched in these pathways,and the MCC algorithm screened the top 5 key genes,which were shown to be HRAS,KRAS,PTEN,VEGFA,and SRC. HRAS and VEGFA were selected for subsequent experiments,and the results showed that after CoCl2 treatment,the viability of HT22 cells was significantly decreased(P<0.05),HRAS was significantly down-regulated and VEGFA was significantly up-regulated in CoCl2-treated cells(P<0.05),the levels of TNF-α,IL-1β,and IL-6 were significantly increased(P<0.001). However,treatment with overexpression of HRAS or low expression of VEGFA led to an increase in the activity of cell growth(P<0.05) as well as a significant decrease in TNF-α,IL-1β,and IL-6 levels(P<0.001). CONCLUSION In sleep apnea,HRAS or VEGFA may lead to cognitive impairment by affecting inflammatory factors.
