Objective:To observe the effect of point injection at Zusanli(ST36)plus abdominal point application on gastrointestinal dysfunction after laparoscopic surgery.Methods:A total of 204 patients with gastrointestinal dysfunction after laparoscopic surgery were recruited and divided into four groups using the random number table method,with 51 cases in each group.The control group received conventional postoperative intervention.In addition to the treatment in the control group,the point injection group was given point injection at Zusanli(ST36),the application group was offered abdominal point application,and the integrated group received point injection at Zusanli(ST36)and abdominal point application.The treatment lasted 3 consecutive days in all four groups.The recovery time of gastrointestinal function indicators and the incidence rate of postoperative nausea and vomiting(PONV)were observed and recorded.Before and after treatment,the visual analog scale(VAS)was used to assess abdominal pain intensity,the venous blood type 1 helper T cells/type 2 helper T cells(Th1/Th2)was determined,the serum levels of interleukin(IL)-6 and interferon(IFN)-γ were detected using the enzyme-linked immunosorbent assay,and the plasma levels of motilin and gastrin were measured using radioimmunoassay.Results:Compared to the control group,the first exhaust time,the first defecation time,and the time of restoring fluid diet came earlier in the other three groups(P<0.05)and were earlier in the integrated group than in the point injection and application groups(P<0.05).The point injection,application,and integrated groups had a lower PONV incidence rate than the control group,and the integrated group was lower than the point injection and application groups(P<0.05).The intra-group comparisons showed that the VAS score and the levels of IL-6 and INF-γ decreased after treatment in all four groups(P<0.05);the point injection,application,and integrated groups were lower than the control group(P<0.05),and the integrated group was lower than the point injection and application groups(P<0.05).The intra-group comparisons also demonstrated that the levels of Th1/Th2,motilin,and gastrin increased after the intervention in the four groups(P<0.05);the point injection,application,and integrated groups were higher than the control group(P<0.05),and the integrated group was higher than the point injection and application groups(P<0.05).Conclusion:Point injection at Zusanli(ST36)plus abdominal point application can encourage postoperative exhaust,defecation,and the recovery of diet fluid,alleviate postoperative abdominal pain,reduce PONV,balance Th1/Th2,and regulate the secretion of motilin and gastrin in patients with gastrointestinal dysfunction after laparoscopic surgery.

To investigate the expression and distribution of follicular dendritic cell(FDC)and follic-ular helper T cells(Tfh)in mouse spleen and lymph nodes induced by foot-and-mouth virus-like particles(FMDV-VLPs),the recombinant pCMV-HA-HBcAg-VP1-VP4 plasmid was transfected into CHO-K1 cells to prepare FMDV-VLPs,and the recombinant FMDV VP1-VP4 protein was expressed and purified through a prokaryotic expression system.BALB/c mice were subcutaneous-ly immunized with FMDV-VLPs(VLP group)and recombinant FMDV VP1-VP4 protein(VP1-VP4 group),and PBS control group(PBS group)was set up.At 21 d post primary immunization(dpi),booster immunization was carried out.Spleen,shoulder lymph nodes,and submandibular lymph nodes were collected at 7,28,42,72 and 102 dpi,and frozen sections were prepared.Immu-nohistochemical staining was used to observe the expression and distribution of FDC and Tfh.The results showed that the number of FDC and Tfh cells in the VLP group in the spleen and lymph nodes showed a gradual increase from 7 to 42 dpi,and gradually decreased to non-immune levels starting from 72 dpi.The results indicate that FMDV-VLPs can induce the formation of GC in the spleen and lymph nodes,and the number of FDC and Tfh cells in GC can last for at least 42 d.This study provides a theoretical basis for the study of the immune memory response mechanism of B cells induced by FMDV virus-like particles.

Objective To study the effect of diltiazem on coronary microcirculation and vascular endothelial function in patients with acute coronary syndrome(ACS)before surgery.Methods A total of 96 ACS patients admitted to Fengfeng General Hospital of North China Medical and Health Group between October 2023 and October 2024 were selected as subjects.The patients were divided into experimental group(n=48)and control group(n=48)by using a random number table method.The experimental group received slow intravenous infusion of diltiazem dilution before surgery and continued intravenous diltiazem during the procedure,while the control group received normal saline both preoperatively and intraoperatively.During the operation,coronary microcirculation parameters[coronary angiography,myocardial perfusion grading(TIMI),microcirculatory resistance index,intraoperative slow blood flow,and no-reflux status]were monitored.Vascular endothelial indexes(endothelin-1,vascular endothelial growth factor)were detected before and one week after surgery.Cardiovascular adverse events were also observed within six months postoperative.Results Postoperative TIMI myocardial perfusion grading in experimental group was superior to than that in control group,and the incidence of slow blood flow and no reflux during surgery in experimental group were lower than those in control group.The levels of endothelin-1 and vascular endothelial growth factor in experimental group were lower than those in control group,and the incidence of cardiovascular adverse events in experimental group were lower than those in control group,with statistically significant differences(P＜0.05).Conclusion The use of diltiazem before percutaneous coronary intervention in patients with ACS can effectively increase coronary blood flow,improve coronary microcirculation,and protect vascular endothelial function.

Objective:To investigate the infection rate of cytomegalovirus (CMV) and Epstein-Barr virus (EBV) in patients with severe aplastic anemia (SAA) after intensive immunosuppressive therapy in combination with a thrombopoietin receptor agonist (lST+TPO-RA) as well as assess the clinical impact of treatment.Methods:A retrospective, case series study was undertaken involving patients with SAA who were admitted to Soochow Hopes Hematonosis Hospital, The First Affiliated Hospital of Soochow University, and Zhengzhou Third People′s Hospital from June 2022 to February 2025. Thirty patients with complete CMV and EBV monitoring data after IST+TPO-RA treatment were enrolled. The first activation time of CMV and EBV, the maximum viral load, the first negative conversion time, and blood routine tests within 3 days before CMV and EBV positivity, during the positive period, and within 3 days after turning negative were recorded. The patients were followed up for 9 months after the completion of IST. One-way analysis of variance was used to compare the changes of blood routine before and after virus positivity and after turning negative. The χ2 test was used to compare the viral infection rate and the therapeutic effect of IST between the two groups. Results:The 30 SAA patients comprised 15 males and 15 females with an average age of (40.0±16.9) years. Of the 30 patients, 18 (60.0%) were infected with CMV and 6 (20.0%) with EBV. Among them, 17 cases received rabbit anti-human thymocyte immunoglobulin (r-ATG) treatment (r-ATG group), 13 cases received porcine anti-human lymphocyte immunoglobulin (p-ALG) treatment (p-ALG group). The CMV infection rate was significantly higher in the r-ATG group than in the p-ALG group (15/17 vs. 3/13, χ2=13.03, P<0.001); meanwhile, the rate of EBV infection was only slightly higher in the r-ATG group than in the p-ALG group, and the difference did not reach statistical significance (5/17 vs. 1/13, χ2=2.17, P=0.196). In patients infected with CMV, neutrophil, hemoglobin, and platelet counts were significantly decreased during the infection phase, followed by significant increases after CMV clearance ( F=14.48, 11.38, 4.73; all P<0.05). No significant differences in treatment efficacy were found between the r-ATG and p-ALG groups at 3, 6, and 9 months post-IST (all P>0.05). Conclusions:This preliminary study showed that the incidence of CMV and EBV infection in patients with SAA increased after IST, with CMV infections occurring significantly more frequently than EBV infections. The CMV infection rate was significantly higher in patients treated with r-ATG than in those receiving p-ALG. CMV infection was associated with notable alterations in hematological parameters, highlighting the need for close clinical monitoring.

Thoracolumbar spine fracture often leads to severe pain, functional impairments, and neurological deficits, for which open reduction and internal fixation can effectively restore the spinal structural stability. Open decompression and reduction with internal fixation can help relieve spinal cord compression and improve spinal function in cases of concomitant cord injury. Although spinal stability can be restored through surgery, patients often face chronic pain and functional impairments postoperatively. A postoperative rehabilitation program is critical in optimizing therapeutic outcomes, reducing complications, and minimizing the risk of secondary injuries. However, current rehabilitation methods, such as physical therapy, functional training, and pain management, are confronted with problems in clinical practice, including significant variation in efficacy, poor patient adherence, and prolonged rehabilitation period. There is an urgent need for a unified rehabilitation strategy to address these problems. To this end, the Spinal Trauma Group of the Orthopedic Physicians Branch of the Chinese Medical Association and the Spine Health Professional Committee of the Chinese Human Health Technology Promotion Association organized experts from relevant fields to formulate Evidence-based guidelines for rehabilitation treatment after internal fixation of thoracolumbar spine fracture in adults ( version 2025) by integrating evidences from clinical researches and advanced rehabilitation concepts at home and abroad. A total number of 14 recommendations concerning the rehabilitation treatment with multimodal analgesia, psychological intervention, deep vein thrombosis prevention, core muscle and extremity exercise, appropriate use of braces, early weight-bearing, device-aided rehabilitation exercise, neuroregulatory therapy, rehabilitation team were put forward, aiming to standardize the post-operative rehabilitation process following internal fixation, promote the functional recovery, and enhance patients′ quality of life.
