Hernia is a common and frequently occurring condition in general surgery, referring to the displacement of an organ or part of an organ from its normal anatomical position through a congenital or acquired weak point, defect, or space into another area. Its pathogenesis is complex, involving multiple factors such as abdominal wall weakness or increased intra-abdominal pressure. The clinical manifestations of hernia vary depending on its type, location, and severity. As the aging of the population continues to advance, the incidence of hernia has been increasing annually. Animal models serve as an important tool in hernia research. They enable the evaluation of the safety and efficacy of new repair materials and techniques, as well as assisting clinicians in developing new surgical methods and investigating the mechanisms and novel therapies for certain hernia diseases and their complications. Given the significant differences in the pathophysiological mechanisms of different types of hernia diseases, the methods and evaluation criteria for establishing animal models are highly diverse. Furthermore, the methods for establishing animal models are closely related to experimental objectives, and different experimental goals require different animal models. Therefore, selecting appropriate animal models based on experimental objectives is crucial for ensuring the smooth progress of research and obtaining reliable results. To this end, this review summarizes effective methods for establishing animal models for external abdominal hernias (including incisional hernia, inguinal hernia, umbilical hernia, parastomal hernia, incarcerated hernia, and pelvic floor hernia), congenital diaphragmatic hernia, hiatal hernia, and cerebral hernia. It provides a detailed analysis of the advantages, disadvantages, and evaluation criteria of these models. Additionally, this review summarizes recent preclinical applications of new hernia repair materials, aiming to provide references for animal experimental research in the field of hernia studies.

ObjectiveTo evaluate the efficacy and safety of Xiaoji Hufei Formula in protecting children with close contact exposure to influenza， and to provide reference and evidence-based support for better clinical prevention and treatment of influenza in children. MethodsA multicenter， prospective， non-randomized， parallel， controlled trial was conducted from October 2021 to May 2022 in five hospitals， including Dongfang Hospital of Beijing University of Chinese Medicine. Confirmed influenza cases and influenza-like illness （ILI） cases were collected， and eligible children with close contact exposure to these cases were recruited in the outpatient clinics. According to whether the enrolled close contacts were willing to take Xiaoji Hufei formula for influenza prevention， they were assigned to the observation group （108 cases） or the control group （108 cases）. Follow-up visits were conducted on days 7 and 14 after enrollment. The primary outcomes were the incidence of ILI and the rate of laboratory-confirmed influenza. Secondary outcomes included traditional Chinese medicine （TCM） symptom score scale for influenza， influenza-related emergency （outpatient） visit rate， influenza hospitalization rate， and time to onset after exposure to influenza cases. ResultsA total of 216 participants were enrolled， with 108 in the observation group and 108 in the control group. Primary outcomes： （1） Incidence of ILI： The incidence was 12.0% （13/108） in the observation group and 23.1% （25/108） in the control group， with the observation group showing a significantly lower incidence （χ²=4.6， P<0.05）. （2） Influenza confirmation rate： 3.7% （4/108） in the observation group and 4.6% （5/108） in the control group， with no statistically significant difference. Secondary outcomes： （1） TCM symptom score scale： after onset， nasal congestion and runny nose scores differed significantly between the two groups （P<0.05）， while other symptoms such as fever， sore throat， and cough showed no significant differences. （2） Influenza-related emergency （outpatient） visit rate： 84.6% （11 cases） in the observation group and 96.0% （24 cases） in the control group， with no significant difference. （3） Time to onset after exposure： The median onset time after exposure to index patients was 7 days in the observation group and 4 days in the control group， with a statistically significant difference （P<0.05）. ConclusionIn previously healthy children exposed to infectious influenza cases under unprotected conditions， Xiaoji Hufei formula prophylaxis significantly reduced the incidence of ILI. Xiaoji Hufei Formula can be recommended as a specific preventive prescription for influenza in children.

Objective:To investigate the effect of ultrasound-guided scalp nerve block (SNB) combined with dexmedetomidine on cerebral blood flow after craniotomy in patients with acute traumatic brain injury (TBI).Methods:A randomized controlled design was conducted. Patients aged 25-65 years, with ASA physical status I–III and Glasgow Coma Scale scores of 9-12, who underwent craniotomy for acute TBI at Kunshan Traditional Chinese Medicine Hospital between January 2024 and February 2025 were selected. Patients with unstable vital signs, cranial tumors, cardiovascular diseases, local anesthetic allergies, or infections at the puncture site were excluded. Using a random number table, patients were divided into two groups: the ultrasound-guided SNB combined with dexmedetomidine group (SD group) and the dexmedetomidine-alone group (D group). General clinical data, peak systolic velocity (PSV), mean blood flow velocity (MBFV), intracranial pressure (ICP), S100 calcium-binding protein beta (S-100β protein), neuron-specific enolase (NSE) levels, and postoperative complications were compared. Dynamic changes in PSV and MBFV were analyzed using repeated measures analysis of variance, while inter-group comparisons used independent sample t-tests. Results:A total of 79 patients were included, with 40 in the SD group and 39 in the D group. There were no significant differences in general clinical data between the two groups (all P>0.05). In the D group, PSV and MBFV at T 1 and T 2 were significantly higher than at T0 [(125.04±20.43) cm/s vs. (126.83±21.76) cm/s vs. (110.63±18.49) cm/s, P=0.001; (61.75±8.34) cm/s vs. (62.81±8.54) cm/s vs. (57.82±6.93) cm/s, P=0.017], whereas no significant differences were observed in the SD group (all P>0.05). PSV, MBFV, ICP, S-100β protein, and NSE levels at T1 and T2 in the SD group were lower than those in the D group (all P<0.05). The incidence of postoperative hypertension, agitation, and the use rate of vasoactive drugs were also lower in the SD group compared to the D group (all P<0.05). Conclusion:The application of ultrasound-guided SNB combined with dexmedetomidine in TBI patients after craniotomy can help stabilize cerebral blood flow and ICP, mitigate neuronal injury, and reduce the incidence of postoperative complications.

Objective To investigate the effect of arthroscopic surgery on anterior ankle impingement syndrome.Method Arthroscopic surgery was performed on 42 patients with anterior ankle impingement syndrome admitted to the People's Hospital of Wuhan University from April 2016 to October 2021.The patients were followed up for 14 to 26 months.The visual analogue scale(VAS)was used to evaluate pain,and the American Orthopaedic Foot and Ankle Society,AOFAS(Ankle and hind foot function scores)were used to evaluate the therapeutic effect and ankle joint function,and to compare the preoperative and postoperative changesResults The wounds of all patients were healed in stage I without infection,nerve,blood vessel or tendon injury.The AOFAS score was(45.52±6.64)before surgery,(76.33±6.52),(92.86±3.48)and(94.95±3.68)at 1 month,3 months and 14 months after surgery,respectively.The VAS score was(7.95±0.70)before surgery,(3.86±0.65),(1.83±0.79)and(1.24±0.96)at 1 month,3 months and 14 months after surgery,respectively.AOFAS scores and VAS scores at 1 month,3 months and 14 months after operation were significantly improved compared with those before operation,and the difference was statistically significant(P＜0.05),there was significant improvement at 3 and 14 months after surgery compared with 1 month after surgery,and the difference was statistically significant(P＜0.05),14 months after surgery was better than 3 months after surgery,but the difference was not statistically significant(P＞0.05).Conclusion Arthroscopic surgery in the treatment of anterior ankle impingement syndrome,less trauma,quick recovery,good effect,can be effective in the treatment of ligamentous and osteochondral injury,mid-term follow-up effect is stable.

Objective To investigate the effect of embryonic inflammatory exposure on the response of mouse offspring to interphotoreceptor retinoid-binding protein(IRBP)-induced experimental autoimmune uveitis(EAU).Methods RNA transcriptome sequencing data from eyeballs of C57BL/6J mouse offspring born to mothers with active EAU were used to screen immune-associated differentially expressed genes in the eyes of the exposed offspring.Gene fragments overlapping in the two datasets were screened using Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses to identify biological pathways associated with the gene fragments.Hub genes were identified from these intersecting genes by protein-protein interaction network analysis.EAU models of maternal uveitis were established by immunization with IRBP651-670,and expression levels of the pivotal genes in the offspring exposed to inflammation by maternal uveitis were examined by fluorescence quantitative polymerase chain reaction.EAU severity,T lymphocyte proliferation,and serum cytokines were detected to investigate the immune effect in offspring from mothers with an active inflammation response to IRBP induction.Results Microarray analysis identified 72 immune-related differentially expressed genes in exposed samples compared with the findings in control samples.These genes were mainly enriched in Toll-like receptor signaling,mitogen-activated protein kinase signaling,and B cell receptor signaling pathways.Protein-protein interaction network interaction analysis screened out four hub genes,Psmc5,Psmc3,Psmd4,and Psmd8,and mRNA levels of these four genes were increased in the adult offspring from mothers with active uveitis compared with the findings in healthy offspring.In addition,the group induced with 150 μg IRBP showed an increase in the severity of clinical and pathological outcomes in offspring with EAU affected by active inflammation,compared with the healthy offspring group(P=0.0087,P=0.0410).Meanwhile,T cell proliferation in the offspring was enhanced during the inflammatory activity stage and secretion of the inflammatory cytokines interleukin(IL)-17 and IL-6 was increased(P=0.0450,P=0.0300).Conclusions Psmc5,Psmc3,Psmd4,and Psmd8 may be important genes exacerbating uveitis in offspring of mothers with active uveitis,associated with increased T cell proliferation and production of IL-17 and IL-6.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

OBJECTIVE To explore the way to re-use epidermal growth factor receptor-tyrosine kinase inhibitors （EGFR-TKI） in patients with EGFR-TKI-induced interstitial pneumonia （IP）， using osimertinib as an example. METHODS The IP treatment regimen and re-use of EGFR-TKI regimen in a patient who developed IP after the use of osimertinib were analyzed. And a literature review was made by combining the characteristics of the cases which reported in the literature and the characteristics of this case. RESULTS The patient’s IP symptoms due to treatment with osimertinib had resolved after treatment. The patient’s IP symptoms also did not worsen after using almonertinib in combination with hormones as re-use of EGFR-TKI regimen. However， almonertinib was discontinued as the patient experienced disease progression. The adverse reactions of IP needed to be dealt with in time， the EGFR-TKI should be discontinued and symptomatic treatment should be given. CONCLUSIONS EGFR-TKI targeted therapy could be re-selected by replacing EGFR-TKI， adjusting the dose of EGFR-TKI， and using hormones in combination. EGFR-TKI-induced adverse drug reactions of IP are rare， but need to be observed closely. If other EGFR-TKI is used， close monitoring of adverse reactions and curative effects are also required in order to adjust the patient’s treatment plan in time.

Syndrome differentiation and treatment is a unique mode of diagnosis in traditional Chinese medicine （TCM）. The establishment of scientific and standardized syndrome diagnosis standards is an important link to evaluate the clinical efficacy of TCM objectively and systematically， and also a prerequisite for the promotion and development of TCM to obtain international recognition. This article reviewed the basic modes and existed problems of the current syndrome diagnosis criteria， and proposed to construct a multidimensional core information set integrating the minimized core symptoms， the artificial intelligence signs， the multi-modal laboratory indicators， and multi-omics specific markers， so as to present syndrome characteristics from multiple perspectives systematically. This paper also described the basic mode， constructure， as well as the process and methodology to be adopted in the establishment of the standardized diagnostic research method. The core information set of diagnostic symptoms not only took into account the specificity of the disease， but also improved the inconsistency due to the complexity and subjectivity of the syndrome differentiation， thereby providing a methodological basis for the standardization of TCM syndrome differentiation in clinical research.

Colorectal cancer is one of the most common malignant tumors of digestive tract. In 2020， 1.93 million new cases of colorectal cancer were diagnosed globally， ranking third in the global incidence spectrum， and 930 000 new deaths were reported， ranking second in the global cause of death spectrum. Meanwhile， the medical cost of metastatic colorectal cancer is the highest among all stages. A large number of studies have demonstrated that traditional Chinese medicine（TCM） treatment can bring clinical benefits to patients with metastatic colorectal cancer with unique efficacy. In order to further standardize the TCM diagnosis and treatment for metastatic colorectal cancer and improve the level of TCM diagnosis and treatment， Xiyuan Hospital， China Academy of Chinese Medical Sciences， together with other relevant units in China， according to the guideline development process of the World Health Organization Handbook for Guideline Development and the relevant requirements of the Clinical Evidence Grading Criteria on TCM Based on Evidence Body， the Regulations for Group Standards of China Association of Chinese Medicine and others， combined with the characteristics of TCM diagnosis and treatment and the actual situation in China， the Guidelines for TCM Diagnosis and Treatment of Metastatic Colorectal Cancer was developed in accordance with the Catalogue of TCM Diagnosis and Treatment Plans for 105 Diseases in 24 Specialties issued by Department of Medical Administration of National Administration of TCM.
