Traditional Chinese medicine(TCM) is the pillar for the development of motherland medicine, and animal medicine has a long history of application in China, characterized by wide resources, strong activity, definite efficacy, and great benefits. It has significant potential and important status in the consumption market of raw materials of TCM. In the context of global climate change, farming system alterations, and low renewability, the depletion of wild medicinal animal resources has accelerated. Accordingly, the conservation and sustainable utilization of wild resources of animal medicinal materials has become a problem that garners increasing attention and urgently needs to be solved. This paper summarizes the current situation of domestic and foreign medicinal animal breeding and research progress in industrial application in recent years and points out the issues related to standardized breeding, germplasm selection and breeding, and quality evaluation standards for medicinal animals. Furthermore, this paper discusses standardized breeding, quality standards, resource protection and utilization, and the search for alternative resources for rare and endangered medicinal animals. It proposes that researchers should systematically carry out in-depth basic research on animal medicine, improve the breeding scale and level of medicinal animals, employ modern technology to enhance the quality standards of medicinal materials, and strengthen the research and development of alternative resources. This approach aims to effectively address the relationship between protection and utilization and make a significant contribution to the sustainable development of medicinal animal resources and the animal-based Chinese medicinal material industry.

Objective To evaluate the frailty status and risk factors among hospitalized elderly patients after percutaneous coronary intervention(PCI),and to provide a reference for improving and delaying their frailty.Methods From March to August 2024,using convenience sampling,patients aged over 75 years who underwent PCI in a tertiary cardiovascular disease specialist hospital in Beijing were selected as the survey participants.Patient-related informations were collected through a self-designed general information questionnaire.The Fried Phenotype Frailty Scale,the Katz Activities of Daily Living,Lawton Instrumental Activities of Daily Living(IADL)scale,the Charlson Comorbidity Index,the Morse Fall Scale,the Mini Nutritional Assessment-Short Form(MNA-SF),and the 15-item Geriatric Depression Scale(GDS-15)were evaluated postoperatively until discharge.Univariate and multivariate logistic analyses were conducted to identify factors associated with frailty among patients after PCI.Results A total of 278 patients were included.The incidence of frailty after PCI was 52.16％.Based on Fried Phenotype scores,patients were divided into a non-frail group and a frail group.Univariate analysis showed statistically significant differences between the 2 groups in terms of age,gender,hemoglobin,NT-ProBNP,LVEF,IADL scores,living alone status,nutrition status,falls risk,and depression level(P＜0.05).Multivariate logistic regression analysis revealed that age,Lawton IADL scores,falls risk,nutrition status,depression level were factors influencing frailty,with odds ratios of 1.167,0.575,1.597,0.399,and 3.610,respectively(P＜0.05).Conclusion The incidence of frailty is high among patients aged over 75 years after PCI,and there are multiple risk factors affecting their frailty status.Clinical healthcare providers should prioritize long-term management of these patients and implement comprehensive interventions with the consideration of their physiological,psychological,and social conditions.

Objective:To compare the efficacy of cannulated screw internal fixation combined with quadratus femoris bone flap with preservation of the posterior superior retinaculum and cannulated screw internal fixation alone in the treatment of femoral neck fracture in young and middle-aged patients.Methods:A retrospective cohort study was conducted to analyze the clinical data of 83 young and middle-aged patients with femoral neck fracture admitted to the 920th Hospital of Joint Logistic Support Force of PLA from January 2018 to January 2023, including 56 males and 27 females, aged 28-55 years [(42.7±3.2)years]. According to Garden classification, the fractures were classified as type III in 22 patients and type IV in 61. Based on Pauwels classification, the fractures were classified as type I in 15 patients, type II in 38 and type III in 30. Forty patients were treated with cannulated screw internal fixation combined with modified quadratus femoris bone flap (cannulated screw combined with bone flap group) and 43 with cannulated screw internal fixation alone (cannulated screw group). The two groups were compared in terms of the operation time, intraoperative blood loss, time to weight-bearing, length of hospital stay, and wound healing. The visual analogue scale (VAS) scores and Harris hip function scores at 1, 3, 6, 12 months after surgery and at the last follow-up. The postoperative complication rate was detected.Results:All the patients were followed up for 20-70 months [(40.0±1.2)months]. The operation time and intraoperative blood loss were (105.2±2.7)minutes and (100.6±16.3)ml in the cannulated screw combined with bone flap group, which were longer or more than (92.4±4.7)minutes and (92.5±14.6)ml in the cannulated screw group ( P<0.01). The time to weight-bearing was (12.1±1.4)weeks in the cannulated screw combined with bone flap group, shorter than (23.6±1.2)weeks in the cannulated screw group ( P<0.01). There was no statistically significant difference in the length of hospital stay between the two groups (P>0.05). The incisions in both groups were healed by first intention. At 1 month after surgery, no statistically significant difference was observed in VAS scores between the two groups ( P>0.05); at 3, 6, 12 months after surgery and at the last follow-up, the VAS scores were (6.6±0.2)points, (4.5±0.3)points, (3.2±0.5)points, and (2.6±0.4)points in the cannulated screw combined with bone flap group, lower than (7.0±0.1)points, (5.2±0.2)points, (3.9±0.4)points, and (3.3±0.1)points in the cannulated screw group ( P<0.05 or 0.01). At 1 and 3 months after surgery, no statistically significant difference was observed in the Harris hip function scores between the two groups ( P>0.05); at 6, 12 months after surgery and at the last follow-up, the Harris hip function scores were (82.2±1.7)points, (90.0±1.4)points, and (91.6±1.0)points in the cannulated screw combined with bone flap group, higher than (75.2±1.7)points, (83.4±1.9)points, and (85.2±0.7)points in the cannulated screw group ( P<0.01). At the last follow-up, in the cannulated screw combined with bone flap group, the Harris hip function was rated excellent in 32 patients, good in 5, and fair in 3, with an excellent and good rate of 92.5%, while in the cannulated screw group, the Harris hip function was rated excellent in 20 patients, good in 13, and fair in 10, with an excellent and good rate of 76.7% ( P<0.05). The postoperative complication rate was 5.0% (2/40) in the cannulated screw combined with bone flap group, significantly lower than 23.2% (10/43) in the cannulated screw group ( P<0.05). Conclusion:Compared with cannulated screw internal fixation alone, cannulated screw internal fixation combined with quadratus femoris bone flap with preservation of the posterior superior retinaculum has the advantages of earlier weight-bearing, less pain, better recovery of hip joint function, and lower incidence of postoperative complications in the treatment of femoral neck fracture in young and middle-aged patients, despite longer operation time and more intraoperative blood loss.

Objective There are complex pathophysiological changes in each component of cerebral tissue after cerebral ischemia-reperfusion injury，and routine neuroprotective strategies fail to exert an effective therapeutic effect in clinical practice. However， the proposal of neurovascular unit（NVU） provides a new conceptual framework for a more comprehensive understanding of the pathophysiological process for interactions between each component of cerebral tissue after cerebral ischemia-reperfusion injury， laying a theoretical foundation for investigating new targets for clinical treatment. Methods A novel NVU in vitro model was established in Transwell co-culture plate using the neurons， astrocytes， and brain microvascular endothelial cells （BMECs） derived from the cortex of Sprague-Dawley rats， and MTT assay was used to measure cell viability in the modified and classical NVU models after OGD/R injury for 1 hour. Results An in vitro NVU model with the three-layer structure of neurons， astrocytes， and BMECs from the top to the bottom was successfully established using Transwell co-culture plate. After OGD/R injury for 1 hour， the neurons in the modified in vitro NVU model showed a significantly higher viability than those in the classical NVU model （P<0.05）， while there were no significant differences in the viability of astrocytes and BMECs between the two models （P>0.05）. Conclusion The modified in vitro NVU model is more suitable for the research on ischemic cerebrovascular disease.

Hepatic encephalopathy(HE),a neuropsychiatric syndrome caused by acute or chronic liver failure or portosystemic shunting,is characterized by metabolic disturbances and varying degrees of cognitive dysfunction.HE is one of the most common complications and is the leading cause of mortality in cirrhotic patients.Although the exact pathogenesis of HE has not yet been fully elucidated,recent advances have improved our understanding of its pathophysiology,leading to evolving therapeutic strategies.This review summarizes the mechanisms underlying HE and the latest progress in its treatment,aiming to enhance the knowledge and improve diagnosis and therapy.

Sarin(GB)is a typical representative of nerve agents with high toxicity,and very low amount can cause death.GB can cause water and atmospheric environment poisoning,so the detection of GB in water and air is of great significance.In this work,a colorimetric sensor array(CSA)based on GB inhibition of cholinesterase activity was constructed to detect GB with high selectivity.A 4×4 colorimetric array was constructed using acetylcholinesterase(AChE),butyryl cholinesterase(BuChE)and the corresponding substrate acetylthiocholine iodide(S-ACh),butyryl thiocholine iodide(S-BCh),acetylcholine chloride(ACh),butyryl choline chloride(BCh)and 2,6-dichloroindophenol ethyl ester(DCIE).The linear curve of the sensor was Y=131.3×lgC+271.6(R2=0.997),where Y was the array response Euclidean distance,C was the concentration of GB(mg/L),the linear range was 0.03?0.32 mg/L,and the detection limit was 27.6 μg/L.The method could effectively distinguish chemical warfare agents(CWA)such as VX,Soman(GD),mustard gas(HD),Louie reagent(L),and had high anti-interference ability,sensitivity and good repeatability.It was successfully applied to the detection of GB in simulated water and simulated air samples,and the sample recovery rate was 97.2% ?100.9%.This method would be potentially applied to the field rapid detection of nerve agents.

Objective:To analyze the clinical features and prognosis of acute B lymphoblastic leukemia (B-ALL) children carrying a TCF3: : PBX1 fusion gene and to evaluate the prognostic value of this gene.Methods:Retrospective cohort study.A total of 2 164 B-ALL children aged 0-18 years diagnosed and treated at 19 pediatric centers from October 2016 to June 2022 were enrolled.They were divided into the positive group and the negative group according to whether they carried a TCF3: : PBX1 fusion gene.The clinical characteristics, treatment response, adverse reactions, and prognosis of the 2 groups of patients were analyzed.The rank sum and Kruskal-Wallis tests were used to compare two and more than two groups of numerical variables, respectively.Fisher′s exact test was used to compare categorical variables.Results:Among the 2 164 patients, 116 (5.4%) were TCF3: : PBX1 positive, of which 70 patients were female, accounting for 60.3%.There were 840 female patients in the TCF3: : PBX1-negative group, accounting for 41.0%.There was a significant difference in the ratio of females between the TCF3: : PBX1-positive and TCF3: : PBX1-negative groups ( P<0.001).No significant difference was observed in age of onset between the two groups( P>0.05).The proportion of bone marrow naive cells [54.00 (14.00, 76.50)% vs.29.00 (3.00, 68.00)%], white blood cell counts [25.30 (10.46, 60.94)×10 9/L vs.9.03 (4.38, 30.73)×10 9/L] and hemoglobin counts [82.00(63.00, 101.00) g/L vs.74.00(60.00, 90.00) g/L] in the TCF3: : PBX1-positive group were significantly higher than those in the negative group at the onset (all P<0.05).In terms of treatment response, the proportion of peripheral blood naive cells on Day 8 in the TCF3: : PBX1-positive group was significantly higher than that in the negative group [2.00 (0, 9.00)% vs.0 (0, 2.00)%, P<0.001].The proportion of minimal residual disease <0.1% on Day 15 in the TCF3: : PBX1-positive group was significantly higher than that in the negative group ( P=0.038).There were no significant differences in cumulative recurrence rate, treatment-related mortality (TRM), and overall survival (OS) between the TCF3: : PBX1-positive group and TCF3: : PBX1-negative group (all P>0.05).The cumulative recurrence risk of TCF3: : PBX1-positive patients was 9.646 times higher than that of ETV6: : RUNX1-positive patients with better prognosis( HR=9.646, 95% CI: 1.026-90.700, P=0.047).There were no significant differences in TRM and OS between TCF3: : PBX1-positive and ETV6: : RUNX1-positive patients (all P>0.05).A significant enrichment of PAX5 mutations was detected in TCF3: : PBX1-positive patients.Among the 7 high-risk TCF3: : PBX1-positive patients in a single center, 4 patients had PAX5 mutations, and this proportion was significantly higher than that in other patients ( P<0.001). Conclusions:B-ALL children carrying a TCF3: : PBX1 fusion gene have a high remission rate and good long-term prognosis after intensive chemotherapy.It is suggesting that TCF3: : PBX1-positive B-ALL patients should be rated at intermediate risk to receive intensive chemotherapy.
