ObjectiveTo observe the effects of Yiqi Huoxue Jiedu formula（YHJF） on immune cell exhaustion in the spleen of septic mice and to explore and validate its potential intervention targets. MethodsMice were randomly divided into the sham-operated， model， low-dose YHJF（4.1 g·kg^-1）， and high-dose YHJF（8.2 g·kg^-1） groups. Except for the sham-operated group， a cecal ligation and puncture（CLP） procedure was performed to establish a mouse sepsis model. The treatment groups received oral administration of the corresponding doses， while the sham-operated and model groups received an equal volume of physiological saline. After the intervention， the 7-day survival rate of each group was recorded， and spleen samples were collected 72 h post-intervention， and the spleen index was calculated. Terminal deoxynucleotidyl transferase deoxyuridine triphosphate（dUTP） nick end labeling（TUNEL） staining was used to detect apoptosis in spleen cells. Enzyme-linked immunosorbent assay（ELISA） was performed to measure the levels of interleukin（IL）-4 and IL-10 in the serum. Transcriptomics and metabolomics were used to screen for differentially expressed genes（DEGs） and differential metabolites in the spleen， followed by bioinformatics analysis to identify key targets. Real-time quantitative polymerase chain reaction（Real-time PCR）， flow cytometry， and multiplex immunofluorescence were used to verify the expressions of key genes and proteins. ResultsThe high-dose YHJF group significantly improved the 7-day survival rate of septic mice（P0.05）. Compared with the sham-operated group， the model group showed a significant increase in apoptosis of spleen cells and a decrease in the spleen index at 72 h post-modeling， with markedly elevated peripheral serum IL-4 and IL-10 levels（P0.01）. Compared with the model group， the high-dose YHJF group showed a reduction in apoptosis of spleen cells， an increase in the spleen index， and a significant decrease in peripheral serum IL-4 and IL-10 levels（P0.05）. Spleen transcriptomics identified 255 DEGs between groups， potentially serving as intervention targets for YHJF. Gene Ontology（GO） enrichment analysis revealed that DEGs were mainly involved in biological processes such as natural killer（NK） cell-mediated positive immune regulation， cell killing， cytokine production， positive regulation of innate immune cells， and interferon production. Kyoto Encyclopedia of Genes and Genomes（KEGG） pathway enrichment analysis showed that DEGs were mainly involved in cytokine-cytokine receptor interactions， viral protein interactions with cytokines and cytokine receptors， chemokine signaling pathway， and nuclear transcription factor-κB（NF-κB） signaling pathway. Protein-protein interaction（PPI） network analysis identified CD160， granzyme B（GZMB）， and chemokine ligand 4（CCL4） as key targets for YHJF in treating sepsis. Metabolomics identified 46 differential metabolites that were significantly reversed by YHJF intervention， and combined transcriptomics and metabolomics analysis identified 17 differential metabolites closely related to CD160. Pathway enrichment revealed that these metabolites were mainly involved in glycerophospholipid metabolism， arachidonic acid metabolism， glycosylphosphatidylinositol（GPI） anchor biosynthesis， linoleic acid metabolism， and α-linolenic acid metabolism pathways. Verification results showed that， compared with the sham-operated group， the model group exhibited significantly elevated CD160 mRNA expression level in the spleen， along with markedly decreased CCL4 and GZMB mRNA expression， and had a significant increase in CD160 expression on the surface of natural killer T（NKT） cells in the spleen（P0.01）. Compared with the model group， the high-dose YHJF group had a significant decrease in CD160 mRNA expression in the spleen， a significant increase in CCL4 and GZMB mRNA expressions. Further flow cytometry and immunofluorescence revealed that compared with the sham-operated group， CD160 expression on the surface of splenic NKT cells in the model group was significantly increased（P0.01）， while high-dose YHJF intervention significantly reduced CD160 expression（P0.01）. ConclusionYHJF may alleviate NKT cell exhaustion in sepsis by downregulating the expression of the negative co-stimulatory molecule CD160， and this regulatory effect is closely related to fatty acid metabolism pathways. This study provides new insights and targets for further exploration of strengthening vital Qi and detoxifying strategy to improve immune cell exhaustion in acute deficiency syndrome of sepsis.

Objective: To systematically analyzes the impact of blood donor characteristics on red blood cell (RBC) quality and transfusion outcomes, and to provide a scientific basis for optimizing donor selection criteria and developing personalized transfusion strategies. Methods: A literature search was conducted across electronic databases including CNKI, VIP, Wanfang Data, PubMed, and Embase using combinations of keywords such as "donor characteristics", "blood storage lesion", "blood quality", and "transfusion outcomes" for summary and analysis. Results: Factors associated with the blood donor characteristics including demographic characteristics (sex, age, body mass index), lifestyle habits (smoking, alcohol consumption, exercise), and dietary or pharmacological exposures significantly influence blood storage stability and transfusion efficacy by modulating erythrocyte metabolism, oxidative stress levels, and immune properties. Conclusion: The complexity and diversity of the blood donor characteristics are associated with blood quality and transfusion outcomes. Future efforts should focus on refining donor selection criteria and establishing personalized transfusion strategies to enhance blood product quality and improve patient outcomes.

Objectives:To investigate the application value of laparoscopic double stapler firings and double stapling technique combined with rectal eversion and total extra-abdominal resection (LDER) in the anal preservation treatment of low rectal cancer.Methods:Inclusion criteria: (1) age was 18-70; (2) the distance of the lower tumor edge from the anal verge was 4-5 cm; (3) primary tumor with a diameter ≤3 cm; (4) preoperative staging of T1~2N1~2M0; (5) "difficult pelvis", defined as ischial tuberosity diameter<10 cm or body mass index>25 kg/m 2; (6) patients with strong intention for sphincter preservation; (7) no preoperative treatment (e.g., chemotherapy, radiotherapy, molecular targeted therapy, or immunotherapy); (8) no lateral lymph node enlargement; (9) no previous anorectal surgery; (10) patients with good basic condition who could tolerate surgery.

The specific surgical steps are as follows: the distal end of the rectum was dissected to the level of the interspace between internal and external sphincters of anal canal. Five centimeters proximal to the tumor, the mesorectum was ligated, and a liner stapler was used to transect the rectum. The distal rectum with the tumor were then everted and extracted through the anus. The rectum was transected 0.5-1.0 cm distal to the tumor with a linear stapler. Full thickness suture was used to reinforce the stump of the rectum, which was then brought back into the pelvic cavity. Finally, an end-to-end anastomosis between the colon and the rectum was performed. A retrospective descriptive study was performed of the clinical and pathological data of 12 patients with T1-T2 stage low rectal cancer treated with LDER at Henan Provincial People's Hospital from January 2020 to December 2022. Results:All 12 patients successfully completed LDER with sphincter preservation, without conversion to open surgery or changes in surgical approach. The median surgical time was 272 (155-320) minutes, with a median bleeding volume of 100 (50-200) mL. No protective stoma was performed, and all patients received R0 resection. The average hospital stay was 9 (7-15) days. There were no postoperative anastomotic leakage or perioperative deaths. All 12 patients received postoperative follow-up, with a median follow-up of 12 months (6-36 months) and a Wexner score of 8 (5-14) at 6 months postoperatively. There was no tumor recurrence or metastasis during the follow-up period.Conclusions:LDER is safe and effective for the treatment of low rectal cancer.

Sepsis is a prevalent critical illness observed in emergency intensive care unit (ICU), characterized by life-threatening organ dysfunction caused by infection-induced inflammatory immune disorders in the body. The suppression of immune function plays a crucial role in the development and progression of sepsis. Traditional Chinese medicine theory of "acute deficiency syndrome" in sepsis shares similarities with the concept of "immunosuppression". According to this theory, ginseng is frequently utilized in clinical treatment of sepsis due to its ability to invigorate vitality and strengthen the body, playing a crucial role in tonifying deficiency and improving the overall health of patients. This paper provides a detailed discussion of the pathophysiological mechanisms of sepsis immune dysfunction and its correlation with "acute deficiency syndrome" in traditional Chinese medicine. It summarizes the current state of modern pharmacological research on ginseng's impact on the body's immune function, discusses relevant research progress and shortcomings regarding ginseng's therapeutic effects on immunosuppression in sepsis, and proposes future research directions.

Objective:To investigate the characteristics of primary catheter malposition (PCM) following totally implantable venous access port (TIVAP) implantation via the internal jugular vein (IJV) and management strategies.Methods:Clinical data of 587 consecutive breast cancer patients undergoing TIVAP implantation via the IJV performed by single team at the Department of Breast Surgery, the First Affiliated Hospital of Zhengzhou University from Aug 2017 to Aug 2022 was retrospectively analyzed.Results:A total of 593 TIVAP were implanted and PCM was found in 18 cases (3.0%). Four hundred and twenty five TIVAP were implanted via the right IJV with one PCM case (0.2%). One hundred and sixty eight TIVAP implantations were performed via the left IJV and PCM occurred in 17 cases (10.1%). The interventional management with a pigtail catheter was performed as a first-line strategy in 11 of the 18 PCM cases, with a success in 10 cases and failure in one. Three cases were successfully managed with the digital subtraction angiography (DSA)-guided open approach. Four cases underwent blind open procedure firstly and 2 suffered a failure.Conclusions:A higher incidence of PCM is found in TIVAP implantations via the left IJV than the right one. The interventional management with a pigtail catheter or the DSA-guided open procedure proves to be feasible for the correction of PCM.

Objective:To investigate preliminary results of chest wall reconstruction with local kiss flap following mastectomy for locally advanced breast cancer (LABC).Methods:Clinical data of the LABC patients receiving treatment at the Department of Breast Surgery, the First Affiliated Hospital of Zhengzhou University between June 2020 and July 2021 was retrospectively analyzed. All patients underwent modified radical mastectomy after neoadjuvant chemotherapy. And the local kiss flap was used for reconstruction of the secondary chest wall soft tissue defects. Two small local flaps were designed intraoperatively and harvested from inferior (flap A) and lateral (flap B) to the defect, respectively, resurfacing a large chest wall soft tissue defect side by side with primary closure of both two donor sites. The flap perfusion was routinely monitored postoperatively. Adjuvant systemic therapies were implemented based on both pre- and post-operative pathological results. And the adjuvant radiotherapy was started immediately after wound healed completely. All cases were followed up regularly.Results:A total of five female patients were included, with an average age of 53.4 (ranging from 41 to 71). Stage Ⅲ (T 3-4N 2-3M 0) breast cancer was diagnosed in all cases. After mastectomy, chest wall soft tissue defect was presented in all cases, ranging from 12.0 cm × 12.0 cm to 22.0 cm × 20.0 cm. The flap A measured from 7.0 cm × 7.0 cm to 14.0 cm × 13.0 cm and the flap B from 5.0 cm × 4.0 cm to 11.0 cm × 7.0 cm. Only 1 flap A suffered tip necrosis and the remnant flaps survived totally. All donor sites recovered uneventfully and no donor-site morbidity was noted. The mean post-operative follow-up period was 15.8 months (ranging from 13 to 20 months). No tumor recurrence or metastasis was noted in all patients, except one patient, who did not receive radiotherapy, suffered local recurrence 4 months after surgery. Conclusion:Given its simplicity and satisfying results, the local kiss flap is a feasible and reliable reconstructive option for chest wall soft tissue defect reconstruction after mastectomy in selected LABC patients.

Objectives:To explore the microanatomy and functional MRI(fMRI) of arcuate fasciculus(AF) and superior longitudinal fasciculus(SLF),and to analyze their functions.Methods:Ten normal adult cadaveric head specimens (20 cerebral hemispheres) were fixed with 10% methanal at the Translational Research Institute for Neurological Disorders of the Wannan Medical College from February to December 2022.The Klingler fiber dissection technique was utilized to perform white matter fiber dissection,with a magnification ranging from 6 to 40.The study focused on the microanatomical structures of the AF and SLF,aiming to explore their relationships with deep brain fibers.Furthermore, six healthy adult volunteers who underwent fMRI of the brain were included.The collected diffusion tensor imaging (DTI) data were processed and integrated with the microanatomical findings for a comprehensive analysis.Results:After removing the gray matter of the cerebral cortex,the superficial U fibers were exposed.The long association fibers that beneath the U fibers were the AF and SLF,which were the main long association fibers in the superficial layers of the brain.The AF could be divided into dorsal and ventral parts,while the SLF could be divided into Ⅰ,Ⅱ,and Ⅲ.SLF Ⅰ lied within the upper bank of the cingulate sulcus,travels medial to the callosal sulcus.The SLF Ⅱ,Ⅲ,and the AF were located on the lateral surface of the brain.By removing the gray matter of the insular cortex and the extreme capsule,exposing the external capsule and claustrum.Subsequently,the AF and SLF Ⅱ,Ⅲ were dissected,revealing the corona radiata and sagittal stratum,along with other deep brain fibers.During the dissection,it was observed that there was a close connection between the AF,SLF Ⅱ,and the deep brain fibers.Furthermore,in the regions above the lateral fissure of the cerebral hemisphere,there was no direct connection of long association fibers between the gray matter cortex and the deep U fibers in the coronal plane.These findings were further supported by DTI studies.Conclusions:The AF and SLF are the major long association fibers that located in the superficial layers of the brain,and closely connect to the gray matter cortex and U fibers,even closely relate with deep brain fibers.In the regions above the lateral fissure of the hemisphere,only the AF and SLF Ⅱ and Ⅲ serve as superficial long association fibers in the anterior-posterior direction.These fibers are likely involved in the transmission of brain functional information between the top and bottom gray matter cortex in the coronal plane above the lateral fissure.
