In recent years， traditional Chinese medicine （TCM） has achieved significant progress in the treatment of inflammatory bowel disease （IBD）. A comprehensive literature search was conducted covering the period from January 1， 2010， to December 30， 2024， across Chinese databases including China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP China Science and Technology Journal Database， and the Chinese Biomedical Literature Service System， as well as international databases such as PubMed， Web of Science， and Embase. The clinical applications and mechanistic studies of TCM in IBD were systematically reviewed. The current status of TCM research on the etiology and pathogenesis of IBD， innovative clinical practices， and multimodal therapeutic approaches， including Chinese herbal formulas， single herbs or active compounds， acupuncture， herbal retention enema， and acupoint application， were summarized， together with their synergistic effects when combined with western medical treatments. The development and application of Chinese patent medicines for IBD are undergoing a profound transition from efficacy validation to mechanistic exploration. Mechanistic studies on the effects of TCM in IBD mainly focus on regulating gut microbiota homeostasis， repairing the intestinal mucosal barrier， and modulating intestinal immune balance. Furthermore， future research directions for TCM-based IBD management are proposed， including the establishment of TCM diagnostic and treatment models， expanding integrated applications of external and internal TCM therapies， innovating personalized treatment strategies， and advancing drug development. These efforts aim to provide insights for the standardized and precision-oriented development of TCM in the diagnosis and treatment of IBD.

Objective To investigate the microbial disinfection and sterilization effectiveness of an electron linear accelerator on the surface and interior of postal packages, and to design and conduct a penetrating radiation disinfection and sterilization experiment. Methods This experiment selected Bacillus pumilus E601 (ATCC 27142) as the indicator microbial strain for radiation. An experimental model of postal package was subjected to penetrating radiation with different dose gradients using high-energy electron beams generated by an S-band 10 MeV electron linear accelerator. The disinfection and sterilization effectiveness was assessed by culturing and counting B. pumilus after high-energy electron beam radiation treatment. A control group was established to analyze the influence of actual absorbed doses at different gradients on the disinfection and sterilization effectiveness of the electron linear accelerator. Results The actual absorbed doses of high-energy electron-beam radiation required to achieve 1-, 3-, and 6-log reductions of B. pumilus were 1.63, 5.07, and 10.22 kGy, respectively. Complete inactivation was achieved at an absorbed dose of 10.92 kGy, which met the processing requirements specified in the technical standard for ionizing-radiation disinfection. Conclusion The experimental data indicated that the actual absorbed dose for B. pumilus is linearly positively correlated with the log reduction of bacterial colonies killed by electron beam radiation. For disinfection and sterilization requirements in different scenarios, the required actual absorbed dose can be achieved by dynamically adjusting the operating speed of the under-beam transmission system.

Objective To analyze the genetic characteristics and variations of influenza A (H3N2) viruses in Ma'anshan from 2022 to 2024, and to provide a scientific basis for local influenza prevention and control. Methods From April 2022 to March 2024, influenza-like illness (ILI) specimens were collected from three national influenza surveillance sentinel hospitals in Ma’anshan. Samples positive for influenza by real-time PCR were subjected to virus culture and identification. A total of 40 representative A/H3N2 strains with hemagglutination titers ≥8 were selected for whole-genome sequencing. Genetic evolution, homology, amino acid variations, and glycosylation sites were analyzed. Results All H3N2 representative strains from the 2022–2023 influenza season belonged to clade 3C.2a1b.2a.1a.1, while those from the 2023–2024 season fell into clade 3C.2a1b.2a.2a.3a.1. The nucleotide and amino acid sequence similarities of HA and NA between the 40 representative strains and the vaccine strain A/Darwin/6/2021 were all above 97.35%. Compared with the vaccine strain, amino acid mutations were identified in antigenic sites A, B, C, and E, as well as in receptor-binding sites of the HA protein. An I222V substitution was detected in the NA protein. The HA protein contained four additional glycosylation sites compared to the vaccine strain, while the glycosylation pattern of the NA protein remained consistent. Conclusion No antigenic drift was observed in the influenza A/H3N2 viruses in Ma'anshan City from 2022 to 2024, but genetic changes such as branching variations, key amino acid substitutions, and an increase in HA glycosylation sites were observed. These findings underscore the importance of sustained molecular surveillance of local influenza viruses.

ObjectiveTo observe the protective effect of Erchentang （ECT） on SiO₂-induced lung injury in rats and to explore its underlying mechanism. MethodsA rat model of lung injury was established by a single intratracheal instillation of 50 mg·mL^-1 SiO₂ suspension. Thirty male Sprague-Dawley （SD） rats were randomly assigned to five groups： control， model， low and high-dose （4.5 g·kg^-1·d^-1 and 9 g·kg^-1·d^-1， respectively） ECT， and dexamethasone （0.2 mg·kg^-1·d^-1）. All the groups were treated for 4 consecutive weeks. Histopathological alterations in the lung tissue were examined by hematoxylin and eosin （HE） staining. The levels of malondialdehyde （MDA）， superoxide dismutase （SOD）， and glutathione peroxidase （GSH-Px） in the lung tissue were measured through biochemical assays. The expression of key molecules in the nuclear factor erythroid 2-related factor 2 （Nrf2）/heme oxygenase-1 （HO-1） pathway was determined by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）， Western blot， and immunofluorescence assay. The primary active components of ECT were identified by ultra-performance liquid chromatography-tandem mass spectrometry （UPLC-MS/MS）， and their binding affinity to Nrf2/HO-1 was assessed by molecular docking. Untargeted metabolomics of the lung tissue was performed based on UPLC-quadrupole time-of-flight mass spectrometry （UPLC-Q-TOF-MS）， and correlation analysis was performed to identify differential metabolites and parameters closely associated with the Nrf2/HO-1 pathway. ResultsCompared with the control group， the model group exhibited a reduction in body weight gain， an increase in lung index， increased MDA content， weakened SOD and GSH-Px activities in the lung tissue， down-regulated mRNA and protein levels of Nrf2 and protein levels of HO-1 and GPX4， and an up-regulated protein level of Keap1 （P<0.05， P<0.01）. Treatment with ECT attenuated the SiO₂-induced decline in body weight （P<0.05）， alleviated inflammatory cell infiltration and silicotic nodule formation in alveoli， and reduced the MDA content and enhanced the SOD and GSH-Px activities in the lung tissue （P<0.05， P<0.01）. UPLC-MS/MS and molecular docking revealed that core components of ECT， such as hesperidin and glycyrrhizic acid， displayed strong binding affinity to Nrf2/HO-1. Molecular biological experiments demonstrated that ECT promoted nuclear translocation of Nrf2， up-regulated the mRNA and protein levels of HO-1 and GPX4， and down-regulated Keap1 expression （P<0.05， P<0.01）. Metabolomic analysis indicated that ECT reversed the SiO₂-induced aberrant expression of metabolites， including linoleic acid and glutamine （P<0.05， P<0.01）. Correlation analysis showed that Nrf2 and HO-1 were positively correlated with SOD and GSH-Px （P<0.05， P<0.01）， but negatively correlated with glutamine and serine （P<0.05， P<0.01）. ConclusionECT may activate the Nrf2/HO-1 pathway through its core active components， thereby regulating oxidative stress and metabolic disorders to ameliorate SiO₂-induced lung injury in rats. This study provides experimental evidence for ECT in the prevention and treatment of occupational lung injury.

Strabismus, a common ocular condition, arises from an imbalance in the extraocular muscle force and deviation of the visual axis due to various factors. Concomitant strabismus is the predominant form of exotropia, with its pathogenesis believed to be associated with hereditary factors, abnormal eye accommodation function, and anomalies in binocular anatomy. Surgical intervention is often necessary for aligning the visual axes of both eyes and facilitating the recovery and establishment of stereoscopic vision. Despite this, the etiology of concomitant exotropia remains incompletely understood. This review consolidates recent research on aberrant molecular expression and pathological morphological changes within extraocular muscles affected by concomitant exotropia, offering insights into disease causation at molecular and pathological levels to underpin future preventive measures and clinical interventions. The discussion encompasses histological changes observed under electron microscopy as well as the impact of heavy chain protein, satellite cells, cadherin, growth factors on extraocular muscle protein expression.

Background: and Purpose Limited evidence exists on the effectiveness of endovascular treatment (EVT) for acute posterior circulation tandem lesion (PCTL). This study aimed to explore the role of extracranial vertebral artery (VA) stenting in patients with PCTL stroke undergoing EVT. Methods: Individual patient data were pooled from the BASILAR (EVT for Acute Basilar Artery Occlusion Study) and PERSIST (Posterior Circulation Ischemic Stroke) registries. Patients with PCTLs who underwent EVT were included in the present cohort and divided into the stenting and nonstenting groups based on the placement of extracranial VA stents. The primary efficacy outcome was the modified Rankin Scale (mRS) scores at 90 days and 1 year. Safety outcomes included 24-hour symptomatic intracranial hemorrhage (sICH) and all-cause mortality at 90 days and 1 year post-surgery. Results: A combined dataset of 1,320 patients with posterior circulation artery occlusion, including 263 (19.9%) with tandem lesions, of whom 217 (median age, 65 years; 82.9% male) met the inclusion criteria for the analysis. The stenting group had 84 (38.7%) patients, while the non-stenting group had 133 (61.3%). After adjustment for the potential confounders, extracranial VA stenting was associated with favorable shifts in mRS scores at both 90 days (adjusted common odds ratio [OR], 2.30; 95% confidence interval [CI], 1.23–4.28; P<0.01) and 1 year (adjusted OR [aOR], 2.04; 95% CI [1.05–3.97]; P=0.04), along with lower rate of mortality at both 90 days (aOR, 0.45; 95% CI [0.21–0.93]; P=0.01) and 1 year (aOR, 0.36; 95% CI [0.16–0.79]; P=0.01), with no significant difference in sICH incidence (aOR, 0.35; 95% CI [0.06–1.98]; P=0.24). Conclusion Extracranial VA stenting during EVT may improve functional outcomes and reduce mortality in patients with PCTL strokes.

Objective:To analyze the efficacy of transjugular intrahepatic portosystemic shunt (TIPS) combined with main splenic artery embolization in the treatment of patients with portal hypertension upper gastrointestinal bleeding complicated with extensive portal vein thrombosis (PVT).Methods:This study was a prospective, single-center, open-label, single-arm clinical trial. In the first phase, 81 patients with portal hypertension upper gastrointestinal bleeding who were admitted to Beijing Shijitan Hospital, Capital Medical University from January 2018 to December 2018 were consecutively enrolled, including 57 males and 24 females, with the age of (51.3±10.4) years. During TIPS surgery, the pressure of the portal vein before and after the balloon blocking the splenic artery was measured to clarify the contribution of the splenic artery to portal hypertension. In the second stage, from January 2019 to December 2022, 104 patients with portal hypertension upper gastrointestinal bleeding complicated with extensive PVT were re-enrolled, including 71 males and 33 females, with the age of (50.9±12.5) years. TIPS combined with main splenic artery embolization was performed, and portal vein pressure was measured before and after embolization. Follow up on the postoperative esophageal and gastric varices of the patients in the second stage.Results:The portal vein pressures before and after the first stage of balloon occlusion of the splenic artery were (35.2±8.4) mmHg (1 mmHg=0.133 kPa) and (24.2±6.3) mmHg, respectively. The pressure after occlusion was lower than that before occlusion, and the difference was statistically significant ( t=10.54, P<0.001). The portal vein pressures before and after the second stage embolization were (36.1±9.5) mmHg and (21.1±4.7) mmHg respectively. The pressure after embolization was lower than that before embolization, and the difference was statistically significant ( t=13.47, P<0.001). In the second stage, among the 104 patients, the proportion of those whose varicose veins disappeared or improved 6 months after the operation was 43.3%(45/104) and 51.0%(53/104), respectively. There were no patients with aggravation or rebleeding due to rupture. One year later, 8 patients (7.7%) had aggravated or ruptured esophageal and gastric varices with bleeding. Two years later, 12 patients (11.5%) had aggravated or bleeding. Conclusion:TIPS combined with main splenic artery embolization can effectively reduce the portal vein pressure in patients with portal hypertension upper gastrointestinal bleeding complicated with extensive PVT, improve the degree of esophageal and gastric varices, and reduce the risk of gastrointestinal bleeding.

Objective To investigate the effects of electroacupuncture for the restoration of muscle regeneration and the secretion of exosomes around acupoints in a model of erector spinae muscle injury.Methods Forty SPF-grade male SD rats were randomly divided into blank group,model group,electroacupuncture group,and electroacupuncture+exosome inhibitor group,with 10 rats per group.Except for the blank group,the erector spinae muscle injury models were established in other groups by intramuscular injection of 0.5%bupivacaine.The blank control group received no treatment,whereas the rats in the electroacupuncture and electroacupuncture+exosome inhibitor groups were treated with electroacupuncture at"Weizhong"(BL40)and"Shenshu"(BL23)acupoints,respectively,stimulation was applied daily for 7 consecutive days,with each session lasting 20 minutes.The parameters used were a sparse-dense wave waveform,a frequency of 2/10 Hz,and a current intensity of 1 mA.The exosome inhibitor GW4869(3 g/L,50 μL per acupoint)was injected 1 h before each electroacupuncture in the electroacupuncture+exosome inhibitor group.After intervention,the erector spinae muscles were collected and observed by HE and Masson staining for morphological changes.The expression of paired box gene 7(Pax7)and recombinant myogenic differentiation(MyoD)was detected by immunohistochemistry,while the expression of myogenin(MyoG)and myosin heavy chain(MyHC)proteins was detected by western blotting.The serum exosomes of rats in each group were extracted and identified by transmission electron microscopy and nanoparticle tracking analysis,and the expression of Alix,differentiation cluster 63(CD63),and tumor susceptibility gene 101(TSG101)proteins were detected by Western blotting.Results Compared with the blank group,the model group,the electroacupuncture group,and the electroacupuncture+exosome inhibitor group exhibited spinae muscle fiber fragmentation,degeneration,necrosis,and inflammatory cell infiltration in HE staining.The result of Masson staining showed that collagen fiber hyperplasia was increased.The model group showed increased expression of MyoD,Pax7,MyoG,MyHC,and CD63,while TSG101 expression was downregulated(P<0.05).In the electroacupuncture group,the expression of MyoD,Pax7,Alix,and TSG101 was elevated(P<0.05),and the expression of MyHC and CD63 was decreased(P<0.05).The electroacupuncture+exosome inhibitor group displayed increased expression of MyHC,Alix,and TSG101(P<0.05),and the expression of CD63 was decreased(P<0.05).Compared with the model group,the electroacupuncture group and the electroacupuncture+exosome inhibitor group showed reduced muscle fiber degeneration,necrotic areas,and inflammatory cell infiltration as observed in HE staining,along with decreased collagen fiber hyperplasia in Masson staining.Specifically,the electroacupuncture group demonstrated increased expression of MyoD,Pax7,MyoG,Alix,and TSG101(P<0.05),and the expression of CD63 was decreased(P<0.05).The electroacupuncture+exosome inhibitor group displayed downregulated expression of Pax7,MyoG,MyHC,and CD63(P<0.05),and the expression of Alix and TSG101 was regulated(P<0.05).Compared with the electroacupuncture+exosome inhibitor group,the electroacupuncture group exhibited less muscle fiber degeneration and necrosis,reduced inflammatory cell infiltration in HE staining,and decreased stained collagen fibers in Masson staining.The electroacupuncture group showed increased expression of MyoD,Pax7,MyoG,MyHC,Alix,and CD63(P<0.05).Conclusion Electroacupuncture can up-regulate the expression of Pax7 and MyoD,and promote the regeneration of erector spinae muscles,which may be related to stimulating the secretion of exosomes around the acupoint.Exosomes may be an important mediator for the efficacy of acupuncture.

This article reports the diagnosis and treatment of two cases of complex ureteral obstruction (UO) in transplanted kidneys managed at Tangdu Hospital of Air Force Medical University of PLA in 2023. UO is a challenging complication following kidney transplantation, with surgical repair being the primary treatment approach. Both patients underwent robot-assisted laparoscopic (RAL) anastomosis of the transplanted kidney collecting system with the autologous ureter. The procedures were successfully performed, and both recipients were discharged without complications. During a six-month postoperative follow-up, the morphology and function of the transplanted kidneys remained stable, with no recurrence of hydronephrosis, fever, pain, urinary frequency, or urgency. This case report provides new insights into the diagnosis and surgical management of complex UO in kidney transplant recipients.

Background and purpose:Members of the serine protease inhibitor(SERPIN)family can influence tumorigenesis,progression,and prognosis by modulating processes such as apoptosis,invasion,metastasis,and angiogenesis in tumor cells.However,their role in pancreatic cancer remains unclear.This study aimed to investigate the impact of high expression of serine protease inhibitor A3(SERPINA3)on the proliferation,apoptosis,migration,and chemoresistance of pancreatic cancer cells and its mechanism.Methods:This study analyzed the SERPINA3 expression levels in the normal pancreatic ductal epithelial cell line hTERT-HPNE and pancreatic cancer cell lines SW1990,Capan-1,PANC-1,and ASPC-1 by real-time reverse transcription quantitative polymerase chain reaction(qRT-PCR).We established gemcitabine-resistant pancreatic cancer cell lines PANC-1/R and ASPC-1/R,and used qRT-PCR assay and cell counting kit-8(CCK-8)to determine the SERPINA3 expression levels in the constructed resistant cell lines and their parental sensitive cell lines,as well as the differences in their chemosensitivity to gemcitabine.We constructed the SERPINA3-knockdown cell line si-SERPINA with siRNA,and the negative control group si-SERPINA#NC with siRNA negative control.We used MDA assay,CCK-8 assay,EdU cell proliferation assay,transwell migration assay,matrigel invasion assay,scratch assay,and apoptotic assay to respectively detect the lipid oxidation levels,proliferation,migration,invasion,wound-healing ability,and the influence on apoptosis of the gemcitabine-resistant pancreatic cancer cells in the si-SERPINA group and the si-SERPINA#NC group.Results:Compared with normal pancreatic ductal epithelial cells hTERT-HPNE,the expression level of SERPINA3 in various pancreatic cancer cell lines was significantly increased(P＜0.05).mRNA and protein expression levels of SERPINA3 in PANC-1/R and ASPC-1/R were significantly increased compared with those in parent cells(P＜0.001).When SERPINA3 was knocked down in PANC-1/R and ASPC-1/R cells,the survival rate of the cells under different concentrations of gemcitabine chemotherapy decreased,and MDA detected that the lipid oxidation level was increased(P＜0.001).In addition,the proliferation rate of PANC-1/R and ASPC-1/R cell lines with SERPINA3 knockout,the number of migrating/invading cells and the healing rate of scratch test were significantly decreased(P＜0.01),and flow cytometry demonstrated that the number of apoptotic cells was increased(P＜0.05).These results suggest that SERPINA3 knockdown can inhibit the proliferation,migration,invasion and wound healing ability of gemcitabine-resistant pancreatic cancer cells,and promote the apoptosis of these resistant cells.Conclusion:SERPINA3 overexpression was found in various pancreatic cancer cells.SERPINA3 overexpression promoted malignant progression and chemotherapy resistance of pancreatic cancer,and interference with SERPINA3 expression promoted ferroptosis and enhanced chemotherapy sensitivity of gemcitabine-resistant pancreatic cancer cells.
