Acute lung injury （ALI） is a critical respiratory emergency caused by various non-cardiogenic factors， including severe pulmonary and extrapulmonary infections， lung contusion， and sepsis. Its pathological features are centered on alveolar-capillary barrier dysfunction， uncontrolled inflammatory responses， and impaired alveolar fluid clearance， manifesting as refractory hypoxemia and respiratory distress， with a poor clinical prognosis. Modern studies have revealed that mitochondrial dysfunction and glucose metabolic reprogramming in macrophages， characterized by hyperactivated glycolysis， drive pro-inflammatory polarization and represent a key mechanism leading to excessive inflammatory responses and disease progression in ALI. Therefore， targeting macrophage glycolysis may be a potential therapeutic strategy for ALI. The Plain Questions： Special Discussion on Channels and Vessels in Huangdi's Internal Classic states that "The spleen disseminates essence upward to the lungs". When the spleen fails in transport and transformation， the distribution of refined nutrients becomes disordered， resulting in the endogenous generation of turbid pathogens that obstruct the pulmonary collaterals， causing failure of lung dispersion and descent and leading to dyspneic reversal. This forms the dynamic pathological pattern of ''deficiency in the root with excess in the manifestation''， thereby proposing the core pathogenesis of ALI as ''spleen deficiency with transport dysfunction and turbid pathogens obstructing the lungs''. This process is intrinsically associated with the inflammatory cascade triggered by disordered macrophage glucose metabolism. Taking the theory of ''spleen failing to disperse essence'' as the entry point， the present study systematically elucidates the progressive pathological mechanism of "energy metabolism disorder-cytokine storm'' in ALI from the perspectives of the ''spleen deficiency-turbid obstruction'' pathogenesis and macrophage glycolysis-pro-inflammatory polarization. In addition， we summarize Chinese medicine compound formulas and monomeric components that ''restore spleen transport and eliminate turbid pathogens''， and explore their potential mechanisms in the treatment of ALI by regulating macrophage metabolic phenotypes to improve the state of ''spleen failing to disperse essence''. This provides a molecular basis for elucidating the ''spleen-lung'' energy metabolism dialogue， deepens understanding of the multi-target regulatory mechanisms of herbal prescriptions， and promotes the deep integration of classical theory with modern medicine.

Objective To explore the value of contrast agent injection protocol based on individualized iodine delivery rate(IDR)applicated in enhanced spectral CT scanning of colorectal cancer.Methods Totally 131 colorectal cancer patients were prospectively collected and randomly divided into conventional group(group A,n=64,contrast agents were injected with routine method)and individualized group(group B,n=67,contrast agents were injected with individualized IDR method).Whole abdominal energy spectrum CT scanning was performed,and 70 keV images at arterial and venous phases(A70 keV)of group A and 40-70 keV images(interval 10 keV)at arterial and venous phases(B40-70 keV)of group B were reconstructed,and iodine-based material maps were reconstructed.Subjective and objective evaluation on quality of enhanced images were performed,lesions'normalized iodine concentration(NIC)were calculated,and the above indexes were compared between groups.Results Iodine intake in group B was lower than that in group A(P＜0.001).The subjective scores of B60 keV images at both arterial and venous phases were the highest,which were not different from those of A70 keV images(both P＞0.05).CT values,signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)of superior mesenteric artery(SMA)and abdominal aorta on arterial B40-60 keV images were higher than those in arterial A70 keV images(all P＜0.05).CT values,SNR and CNR of superior mesenteric vein(SMV)on venous B40-50 keV,as well as CT values and CNR of SMV on venous B60 keV images were all higher than those on venous A70 keV images(all P＜0.05).No significant difference of lesions'NIC in arterial and venous phases was detected between groups(both P＞0.05).Conclusion Injection of contrast agents based on IDR combined with 60 keV single energy image for enhanced energy spectrum CT scanning of colorectal cancer could reduce the amount of contrast agents while do not affect imaging quality.

Objective To compare the therapeutic effects of laparoscopic transabdominal preperitoneal repair(TAPP)and Bassini herniorrhaphy in the treatment of inguinal hernia.Methods 107 patients with inguinal hernia from January 2021 to December 2024 were selected and divided into the Bassini group(53 cases were repaired by Bassini herniorrhaphy)and the TAPP group(54 cases were repaired by TAPP)by random number table method.The surgical-related indicators,pain degree,stress index levels,quality of life,rehabilitation effect and incidence of complications of the two groups of patients were compared.Results The operation time of the Bassini group was significantly shorter than that of the TAPP group,the intraoperative blood loss was significantly more than that in the TAPP group,and the hospital stay was significantly longer than that in the TAPP group,the differences were statistically significant(P<0.05).The visual analogue scale(VAS)score of the two groups of patients after surgery showed a trend of first increasing and then decreasing.The VAS scores of the TAPP group at 3 and 7 days after surgery were significantly lower than those of the Bassini group,and the differences were statistically significant(P<0.05).The levels of cortisol and norepinephrine in both groups of patients 3 days after the operation were significantly higher than those before the operation,and the Bassini group was significantly higher than the TAPP group,the differences were statistically significant(P<0.05).The total effective rate of the TAPP group was 98.15%,significantly higher than that of the Bassini group(83.02%),and the difference was statistically significant(P<0.05).The Short Form 36(SF-36)score of the two groups of patients one month after the operation was significantly higher than that before the operation,and the TAPP group was significantly higher than the Bassini group,the differences were statistically significant(P<0.05).The incidence of complications in the TAPP group was 3.70%,significantly lower than 18.87%in the Bassini group,and the difference was statistically significant(P<0.05).Conclusion Compared with Bassini herniorrhaphy,TAPP can effectively shorten the hospital stay,reduce intraoperative blood loss,lower postoperative pain and stress response,improve the postoperative quality of life of patients,enhance rehabilitation effect and reduce the incidence of complications.It is worthy of clinical promotion and application.

Chronic prostatitis,a common condition in andrology,is clinically characterized by a prolonged course,resistance to treatment,and frequent recurrence.In traditional Chinese medicine,it is classified under the categories of"turbid sperm,""overstrain strangury,"and"vaginal pain."Based on the"host-guest interaction-collateral disease"theory,we believe that healthy qi deficiency,latent pathogenic factors,and collateral obstruction are the primary pathological factors of this disease,which run through the entire process of chronic prostatitis occurrence and development.Accordingly,we propose that obstruction of collaterals and apathesia of the semen chamber are the core pathogenesis.The disease progression can be divided into three pathological stages:"deficiency,depression,and blood stasis."Spleen and kidney deficiency and malnutrition of collaterals form the pathological foundation.In the deficiency stage,treatment strategies involve reinforcing qi and nourishing the collaterals,using Fuzheng Yangrong Decoction.During disease progression,dampness and heat invasion,as well as collateral stagnation qi,are key contributors to disease progression.Thus,treatment focuses on clearing heat and dampness,promoting qi flow,and smoothing the collaterals,achieved with a modified Qiantongding Decoction.In the final stage,blood stasis and collateral obstruction dominate,warranting therapeutic strategies aimed at tonifying and removing blood stasis,addressing both the body and the collaterals simultaneously using the modified Guiling Huayu Decoction.Overall,the clinical treatment generally focuses on the concept of function through free flow,combination of unblocking and tonifying.This study provides a novel perspective and reference for clinical differentiation and treatment of chronic prostatitis.

Objective·To investigate the changes in transcriptome and chromatin accessibility during the differentiation of human embryonic stem cells(hESCs)into neural progenitor cells(NPCs)using in vitro differentiation models and high-throughput multi-omics sequencing technologies.Methods·hESCs were first induced to differentiate into NPCs in vitro using the embryoid body formation method,and cells at both stages were collected.The cell phenotypes were identified by reverse transcription-quantitative real-time PCR(RT-qPCR)and immunofluorescence(IF)staining.Transcriptome sequencing(RNA-seq)was conducted to detect and analyze the differentially expressed genes(DEGs)between hESCs and NPCs.The assay for transposase-accessible chromatin with high-throughput sequencing(ATAC-seq)was employed to assess chromatin accessibility changes between hESCs and NPCs.Motif enrichment analysis was performed on differentially accessible chromatin regions to discover potential regulatory transcription factors.Finally,an integrated analysis of RNA-seq and ATAC-seq data and the protein-protein interaction(PPI)network were performed to identify key genes and regulatory pathways involved in the early stages of neural differentiation in vitro.Results·Both RT-qPCR and IF results indicated that the expression levels of pluripotency markers(NANOG and POU5F1)were high at the hESC stage but significantly decreased at the NPC stage,while early neural differentiation markers(PAX6,SOX1,and NES)were minimally expressed at the hESC stage but markedly upregulated at the NPC stage.RNA-seq analysis revealed that compared to the hESC stage,there were 5 597 genes upregulated and 3 654 genes downregulated at the NPC stage.Gene function enrichment analysis showed that the upregulated genes at the NPC stage were enriched in the functions related to neural development.ATAC-seq analysis demonstrated a total of 27 491 genomic regions had significant changes in chromatin accessibility during the differentiation from hESC to NPC,with 12 381 regions showing increased accessibility and 15 110 regions showing decreased accessibility.Motif enrichment analysis revealed that transcription factor genes such as DLX1 and LHX2 might play an important role in the differentiation process from hESCs into NPCs.Integrated analysis of RNA-seq and ATAC-seq data revealed that overlapping genes with high expression at the NPC stage were mainly enriched in axon guidance,forebrain development,and neuron migration.After neural differentiation,the expression levels of CTNND2 and LHX2 genes increased,and the chromatin accessibility of related genomic regions also increased.PPI network analysis indentified candidate downstream genes including PRKACA,CDH2,and ERBB4.Conclusion·The in vitro differentiation model of hESCs combined with high-throughput multi-omics sequencing technologies can be used to depict the changes in transcriptome and chromatin accessibility during the differentiation of hESCs into NPCs.In this process,the expression levels of genes related to axon guidance,forebrain development,and neuronal migration pathways increase and related chromatin accessibility is enhanced.

Objective:To investigate the differences in prosthesis implantation accuracy, biomechanical indicators, and 2-year postoperative clinical outcomes between robotic-assisted traditional posterior approach (RA-PLA) and robotic-assisted direct anterior approach (RA-DAA) in total hip arthroplasty (THA).Methods:This study is a prospective randomized controlled trial. Patients with unilateral femoral head ischemic necrosis or primary hip osteoarthritis who meet the inclusion and exclusion criteria and were admitted to the Department of Orthopedics,Xinqiao Hospital, Army Medical University from May to September 2022. Divided into RA-PLA group and RA-DAA group through central randomization. Use cumulative and fitting methods to analyze the learning curve of robotic surgery and eliminate cases before the inflection point of the learning curve. Compare the abduction angle and anteversion angle of acetabular cup implantation between two groups of patients, as well as the rate of falling into the safe zone, the difference in length between the two lower limbs, hip joint eccentricity, rotation center height, the complete accuracy of prosthesis planning (the number of cases in which acetabular cup prosthesis, femoral stem prosthesis specifications, and neck shaft angle were completely consistent with surgical planning during surgery/total cases×100%), patient reported outcome indicators (including Harris hip score (HHS), Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC), and 12 item Short Form Health Survey (SF-12) score) and clinical outcomes. Data comparison was conducted using independent sample t-test, Wilcoxon rank sum test, chi square test, Fisher′s exact probability method, or repeated measures analysis of variance. Results:A total of 98 patients were included in this study, with 48 in the RA-PLA group and 50 in the RA-DAA group. After excluding cases before the inflection point of the learning curve, 30 patients were included in each group. There was no statistically significant difference in baseline data between the two groups before surgery (all P>0.05). There was no significant difference in the values of the anterior tilt angle and abduction angle between the two groups of acetabular cups compared to preoperative planning (all P>0.05). The proportion of patients who fell into the Lewinnek and Callanan safe zones was 90.0% (27/30) and 96.7% (29/30), respectively ( χ2=0.268, P=0.605). There was no significant difference in postoperative lower limb length, hip joint eccentricity, and rotation center height deviation and grading between the two groups (all P>0.05). The complete accuracy of prosthesis planning in the RA-DAA group was higher than that in the RA-PLA group (86.7% (26/30) compared to 63.3% (19/30), χ2=4.356, P=0.037).All patients were followed up for more than 2 years. In terms of postoperative HHS, WOMAC, and SF-12 score, there was no statistically significant difference in the inter group effect comparison (all P>0.05), but there was a significant statistical significance in the time effect (all P<0.05). There was no significant difference in the incidence of perioperative complications and adverse events between the RA-DAA group and the RA-PLA group (20.0% (6/30) vs. 13.3% (4/30), χ2=0.480, P=0.488). Conclusions:RA-DAA and RA-PLA techniques can achieve similar clinical efficacy after two years of surgery, and both can achieve similar reconstruction accuracy in terms of acetabular cup implantation angle, lower limb length, hip joint eccentricity, and rotation center height. The accuracy of prosthesis planning in RA-DAA is higher.

Background::An evidence gap still exists regarding the efficacy and safety of tegoprazan in patients with erosive esophagitis (EE) in China. This study aimed to verify the efficacy and safety of tegoprazan vs. esomeprazole in patients with EE in China. Methods::This study was a multicenter, randomized, double-blind, parallel, active-controlled, non-inferiority phase III trial of patients with EE randomized 1:1 to tegoprazan 50 mg/day vs. esomeprazole 40 mg/day. This study was conducted in 32 sites between October 24, 2018 and October 18, 2019. The primary endpoint was the cumulative endoscopic healing rate at week 8. The secondary endpoint included endoscopic healing rate at week 4, changes in the reflux disease questionnaire (RDQ) and gastroesophageal reflux disease health-related quality of life (GERD-HRQL) scores, and symptom improvement. Results::A total of 261 patients were randomized: 132 to the tegoprazan group and 129 to the esomeprazole group. The cumulative endoscopic healing rate at 8 weeks in the tegoprazan group was non-inferior to that of the esomeprazole group (91.1% vs. 92.8%, difference: -1.7%, 95% confidence interval [CI]: -8.5%, 5.0%, P = 0.008). There were no statistically significant differences in the changes in RDQ (total, severity, and frequency) and GERD-HRQL scores between the two groups (all P >0.05). The percentages of days without symptoms, including daytime and nighttime symptoms based on patients' diaries, were similar between the two groups (all P >0.05). In the tegoprazan and esomeprazole groups, 71.5% (93/130) and 61.7% (79/128) of the participants reported adverse events (AEs), 2.3% and 0 experienced serious AEs, while 70.0% and 60.2% had treatment-emergent AEs, respectively. Conclusion::Tegoprazan 50 mg/day demonstrated non-inferior efficacy in healing EE, symptom improvement, and quality of life, and it has similar tolerability compared with esomeprazole 40 mg/day.

Objective:To investigate the long-term efficacy and influencing factors of transcatheter adrenal ablation in patients with primary aldosteronism (PA).Methods:This cohort study retrospectively enrolled PA patients who underwent transcatheter adrenal ablation at Daping Hospital, Army Medical University between January 2021 and December 2024. According to PASO criteria, patients were categorized into groups based on clinical outcomes (complete, partial, or no remission), biochemical outcomes (complete, partial, or no remission), and composite outcomes (complete or incomplete remission). All participants underwent 1-year follow-up, with intergroup comparisons of clinical characteristics and surgical approaches. Multivariate logistic regression models were used to identify factors influencing long-term efficacy post-transcatheter adrenal ablation in PA patients.Results:A total of 122 PA patients were enrolled, aged (47.7±11.1) years, including 55 males (45.1%). Baseline aldosterone-to-renin ratio was 0.43(0.19,0.86)(pmol·L -1)/(μU·L -1). Bilateral adrenal lesions were present in 33 cases (27.1%), while 70 (57.4%) had nodules or adenomas. Adrenal venous sampling confirmed lateralized hypersecretion in 107 patients (87.7%, left or right dominance). According to PASO criteria, 93.4% (114/122) and 95.1% (116/122) of patients achieved complete or partial remission in biochemical and clinical parameters at 1-year post-ablation, respectively. For biochemical outcomes: 40 complete, 74 partial, and 8 no remission. Patients in the partial-remission group were older than those in the no-remission group ((49.4±11.2) vs. (39.6±9.8) years), while complete-remission group had higher bilateral non-lateralized secretion rates than partial remission group (27.5% vs. 4.1%, both P<0.05). For clinical outcomes: 26 complete, 90 partial, 6 no remission. Compared to complete-remission group, partial-remission group had higher male proportion (51.1% vs. 26.9%), longer hypertension duration (4.0 (0.7, 10.0) years vs. 1.5 (0.1, 5.0) years), but lower office diastolic blood pressure ((88±11) mmHg vs. (94±12 mmHg), 1 mmHg=0.133 kPa, all P<0.05). For composite outcomes: 56 complete and 66 incomplete remission. Compared with incomplete remission group, complete remission group had lower prevalence of diabetes (8.9% vs. 22.7%) and higher proportion of bilateral non-lateralized secretion (21.4% vs. 4.6%, both P<0.05). Multivariate logistic regression identified diabetes ( OR=3.635, 95% CI 1.029-12.834, P=0.045) and lateralized secretion ( OR=9.056, 95% CI 2.039-40.212, P=0.004) as independent risk factors for poor composite outcomes after transcatheter adrenal ablation in PA patients, whereas higher office diastolic blood pressure acts as a protective factor ( OR=0.957, 95% CI 0.925-0.992, P=0.015). Conclusion:One year after transcatheter adrenal ablation, the majority of patients achieved complete or partial remission in biochemical and clinical parameters.Patients with non-lateralized adrenal hypersecretion demonstrated a higher likelihood of sustained biochemical remission and superior composite outcomes compared to those with lateralized hypersecretion.
