Portal vein embolization （PVE） can induce atrophy of the embolized lobe and compensatory regeneration of the non-embolized lobe. However， due to inadequate regeneration of future liver remnant （FLR） after PVE， some patients remain unsuitable for hepatectomy after PVE. In recent years， liver venous deprivation （LVD）， which combines PVE with hepatic vein embolization （HVE）， has induced enhanced FLR regeneration. Compared with associating liver partition and portal vein ligation for staged hepatectomy （ALPPS）， LVD triggers faster and more robust FLR regeneration， with lower incidence rate of postoperative complications and mortality rate. By reviewing related articles on LVD， this article introduces the effectiveness of LVD and analyzes the differences and safety of various technical paths， and it is believed that LVD is a safe and effective preoperative pretreatment method.

Acute high-altitude (HA) illnesses (AHAIs), including acute mountain sickness (AMS), HA cerebral edema (HACE), and HA pulmonary edema (HAPE), represent significant health challenges for individuals rapidly ascending to high altitudes. Cytokines (interleukins (ILs)) and chemokines, which are involved in inflammatory and immunological responses, regulate the response of the body to hypoxic stress. Their dysregulation can contribute to the clinical symptoms of AMS, HACE, and HAPE by increasing vascular permeability, causing edema and damaging tissue. AHAIs elevate the levels of pro-inflammatory cytokines and chemokines, such as IL-17, tumor necrosis factor α (TNF-α), IL-1, IL-6, C-X-C motif chemokine ligand (CXCL) 10, CXCL8, C-C motif ligand 2 (CCL2 (CCL2), and CCL3, exacerbating symptoms. Thus, this review focuses on the cytokines and chemokines involved in AHAIs and the molecular mechanisms that extend beyond these cytokines and chemokines in clinical and preclinical contexts. Identifying these mediators and pathways helps researchers design drugs that reduce symptoms, slow disease progression, and enhance outcomes. Cytokines and chemokines have complex functions in these disorders and may serve as prospective therapeutic targets. Finally, we discuss treatment possibilities for AHAIs (drugs, exercise, and other inhibitors). This knowledge will help us to protect and improve the health of individuals at high altitudes.

OBJECTIVE: To investigate the predictive value of early lactate/albumin ratio (LAR) combined with quick sequential organ failure assessment (qSOFA) for the 28-day prognosis of patients with sepsis caused by emergency community-acquired pneumonia (CAP). METHODS: The clinical data of patients with sepsis caused by CAP admitted to the department of emergency of Beijing Haidian Hospital from June 2021 to August 2022 were retrospectively analyzed, including gender, age, comorbidities, lactic acid (Lac), serum albumin (Alb), LAR, procalcitonin (PCT) within 1 hour, and 28-day prognosis. Patients were divided into two groups based on 28-day prognosis, and risk factors affecting patients' prognosis were analyzed using univariate and multivariate Cox regression methods. Patients were divided into two groups according to the best cut-off value of LAR, and Kaplan-Meier survival curves were used to analyze the 28-day cumulative survival of patients in each group. Time-dependent receiver operator characteristic curve (ROC curve) were plotted to analyze the predictive value of sequential organ failure assessment (SOFA), acute physiology and chronic health evaluation II (APACHE II), and qSOFA+LAR score on the prognosis of patients with sepsis caused by CAP at 28 days. The area under the curve (AUC) was calculated and compared. RESULTS: A total of 116 patients with sepsis caused by CAP were included, of whom 80 survived at 28 days and 36 died, 28-day mortality of 31.0%. There were no statistically significant differences in age, gender, comorbidities, pH, platelet count, and fibrinogen between the survival and death groups, and there were significantly differences in blood urea nitrogen (BUN), white blood cell count (WBC), hemoglobin, Lac, Alb, PCT, D-dimer, LAR, as well as qSOFA score, SOFA score, and APACHE II score. Univariate Cox regression analyses showed that BUN, WBC, pH, Lac, Alb, PCT, LAR, qSOFA score, SOFA score, and APACHE II score were associated with mortality outcome. Multifactorial Cox regression analysis of the above variables showed that BUN, WBC, PCT, and APACHE II score were independent risk factors for 28-day death in the emergency department in patients with sepsis caused by CAP [hazard ratio (HR) were 1.081, 0.892, 1.034, and 1.135, respectively, all P < 0.05]. The best cut-off value of early LAR for predicting the 28-day prognosis of sepsis patients was 0.088, the Kaplan-Meier survival curve showed that the 28-day cumulative survival rate of sepsis patients in the LAR ≤ 0.088 group was significantly higher than that in the LAR > 0.088 group [82.9% (63/76) vs. 42.5% (17/40), Log-Rank test: χ² = 22.51, P < 0.001]. The qSOFA+LAR score was calculated based on the LAR cut-off value and qSOFA score, and ROC curve analysis showed that the AUCs of SOFA score, APACHE II score, and qSOFA+LAR score for predicting 28-day death of patients with sepsis caued by CAP were 0.741, 0.774, and 0.709, respectively, with the AUC of qSOFA+LAR score slightly lower than those of SOFA score and APACHE II score, but there were no significantly differences. When the best cut-off value of qSOFA+LAR score was 1, the sensitivity was 63.9% and the specificity was 80.0%. CONCLUSION The qSOFA+LAR score has predictive value for the 28-day prognosis of patients with sepsis caused by CAP in the emergency department, its predictive value is comparable to the SOFA score and the APACHE II score, and it is more convenient for early use in the emergency department.

Objective:To explore the effect of thymol on improving the core symptoms of autism through regulating scinderin expres-sion in autism spectrum disorder(ASD)rats by constructing valproic acid-induced ASD rat model and intervening with thymol.Methods:The ASD-like behaviors of rats were observed using three box social experiment,open field experiment,and youth social ex-periment.RNA-seq was used to detect the expression of RNA in the prefrontal cortex of rats.The protein level of scinderin in the pre-frontal cortex of rats was measured by Western blot.Results:Compared with the rats in the control group,the rats in the model group showed ASD-like behaviors,including decreased social ability,impaired social preference,decreased exploration ability,and repeated stereotyped behavior.Compared with the control group,the model group showed reduced standing times(P<0.001)and increased self combing time(P=0.003).Moreover,the expression level of scinderin in the prefrontal cortex increased in model rats.After thymol treat-ment,the ASD-like behaviors in the model group were significantly improved.Compared with the model group,the number of standing times in the intervention group increased(P<0.001)and the self grooming time decreased(P=0.004).The expression of scinderin basi-cally returned to the normal level.Conclusion:The abnormal expression of scinderin in the prefrontal cortex of ASD model rats can lead to ASD-like behaviors.Thymol intervention can reduce the expression of scinderin and improve the core symptoms of ASD.

Objective To discuss the efficacy of transcatheter arterial chemoembolization(TACE)in combination with targeted therapy and immune checkpoint inhibitors for advanced hepatocellular carcinoma(HCC),and to identify the influencing factors.Methods A total of 60 patients with advanced HCC,who were admitted to the Air Force Medical Center of China from January 2016 to December 2022,were enrolled in this study.Thirty patients received TACE combined with targeted therapy and immune checkpoint inhibitors(TACE-L-P group),and the other 30 patients received TACE combined with targeted therapy(TACE-L group).The progression-free survival(PFS),overall survival(OS),disease control rate(DCR),and objective response rate(ORR)were compared between the two groups.Results In the TACE-L group and TACE-L-P group,the median PFS(mPFS)was 7 months and 10 months respectively(P=0.011),the median OS(mOS)was 15.5 months and 29 months respectively(P=0.014).Child-Pugh class B(HR=3.89,95％CI:1.27-11.94,P=0.018)and Barcelona Clinic Liver Cancer(BCLC)stage C(HR=2.83,95％CI:1.32-6.03,P=0.007)were the independent risk factors for OS,while micro wave ablation(HR=0.21,95％CI:0.07-0.63,P=0.005)and TACE-L-P(HR=0.09,95％CI:0.03-0.3,P=0.001)were the independent protection factors for OS.Besides,elevated bilirubin level(HR=1.03,95％CI:1-1.06,P=0.032)and elevated gamma-glutamyl transferase(GGT)level(HR=1.01,95％CI:1-1.01,P=0.002)were the independent risk factors for disease progression,and TACE-L-P(HR=0.27,95％CI:0.09-0.79,P=0.017)was the independent protection factor for disease progression.The ORR and DCR in TACE-L-P group were remarkably higher than those in TACE-L group,which were 43.4％vs 13.3％and 63.4％vs 23.3％respectively,the differences between the two groups were statistically significant(both P＜0.05).Conclusion In treating advanced HCC,TACE combined with targeted therapy and immune checkpoint inhibitors is superior to TACE combined with targeted therapy in therapeutic efficacy.

OBJECTIVE: To explore the clinical characteristics and genetic etiology of a child with Oral-facial-digital syndrome type Ⅰ(OFDSⅠ). METHODS: A child with OFDSⅠ who received treatment at the Women and Children's Hospital Affiliated to Ningbo University in March 2023 was selected as the study subject. A retrospective research method was used to collect the clinical data of the child. Peripheral venous blood samples were collected from the child, her parents and sister. Genomic DNA was extracted, and whole exome sequencing (WES) was performed. Candidate variants were validated using Sanger sequencing for familial verification. According to the Standards and Guidelines for the Interpretation of Sequence Variants developed by the American College of Medical Genetics and Genomics (ACMG) (hereinafter referred to as the "ACMG Guidelines"), the pathogenicity of the candidate variant was rated. This study was approved by the Medical Ethics Committee of Ningbo University Affiliated Women and Children's Hospital (Ethic No.: EC 2024-063). RESULTS: The child was a prematurely born female with deformities of the oral cavity, fingers, and toes. She was admitted to the Neonatal Department of the Hospital where she was born due to shortness of breath 15 minutes after birth. The WES results indicated that the child has harbored a heterozygous c.710dup (p.Y238Vfs*2) frameshifting variant of the OFD1 gene. Sanger sequencing confirmed that neither of the child's parents nor her sister had carried the same variant. According to the ACMG guidelines, the variant was rated as pathogenic (PVS1+PS4_Moderate+PM2-Supporting+PM6_Supporting+PP4). CONCLUSION Children with OFDSⅠ have clinical features such as oral, finger, and toe deformities. The c.710dup (p.Y238Vfs*2) variant of the OFD1 gene probably underlay the OFDSⅠ in this child. Above result has enriched the mutational spectrum of the OFD1 gene.

OBJECTIVE: To analyze the ABO serological and molecular characteristics of a Chinese pedigree carrying an ABO*cisAB.01 allele for the blood subgroup. METHODS: A proband undergoing blood preparation for a surgery due to an open rupture of the extensor hallucis longus tendon in the left thumb on September 5, 2024 at Weihai Central Hospital and his family members were selected as study subjects. ABO serological type of six individuals from three generations was determined by serological methods. PCR was carried out to amplify exons 6 and 7 of the ABO gene, and the amplified products were directly sequenced. Samples of the proband and his mother, son, and daughter were subjected to clone sequencing analysis. This study was approved by the Medical Ethics Committee of Weihai Central Hospital (Ethics No.: LL-2024-269-01). RESULTS: Serological testing showed that the proband and his mother were of the AB subtype, whilst his daughter was A subtype B, his father was of O, his wife was AB, and his son was A. Direct sequencing showed that the proband's genotype was ABO*cisAB.01/O.01.02, and his mother, son, and daughter had all carried an ABO*cisAB.01 allele. There were significant differences in allelic competition when the A, B and O genes were co-dominant with the cisAB.01 allele, respectively. CONCLUSION There is allelic competition between the cisAB.01 allele and different ABO alleles. Blood type serological tests combined with molecular methods and family investigations can help ascertain and interpret the ABO blood type phenotypes.

Circulating tumor cells(CTCs)are cells that dissociate from the tumor tissue and enter the lymphatic system or bloodstream with close association with tumor metastasis and recurrence.CTCs contain complete pathological information,which can be extracted by isolation,enrichment,and analysis of the CTCs to guide cancer diagnosis and treatment,thereby significantly improving the monitoring efficiency and prognosis of cancer.Compared with tissue biopsy,liquid biopsy with CTCs as a biomarker enables specific and dynamic detection of tumor growth with a less painful experience.For detection of CTCs,the cells must be captured from body fluids,followed then by their release and enrichment.This review summaries the latest research progress in responsive isolation of CTCs(e.g.with light,dielectrophoresis,acoustophoresis and magnetophoresis),chemical isolation(specific molecules and topological structure)and responsive release(e.g.,light,electric,thermal,pH,enzyme responsiveness,and substrates break).Responsive isolation utilizes the differences in physical properties between CTCs and blood cells,while chemical isolation utilizes specific recognition mechanisms to capture the CTCs.These techniques result in low cell damage with a high specificity to facilitate further analysis.Currently,CTC detection has been applied for early diagnosis and prognostic assessment of multiple cancers including lung cancer,liver cancer,colorectal cancer,and prostate cancer.
