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.

Wastewater-based epidemiology has emerged as a transformative surveillance tool for estimating substance consumption and monitoring disease prevalence, particularly during the COVID-19 pandemic. It enables the population-level monitoring of illicit drug use, pathogen prevalence, and environmental pollutant exposure. In this perspective, we summarize the key challenges specific to the Chinese context: (1) Sampling inconsistencies, necessitating standardized 24-hour composite protocols with high-frequency autosamplers (≤ 15 min/event) to improve the representativeness of samples; (2) Biomarker validation, requiring rigorous assessment of excretion profiles and in-sewer stability; (3) Analytical method disparities, demanding inter-laboratory proficiency testing and the development of automated pretreatment instruments; (4) Catchment population dynamics, reducing estimation uncertainties through mobile phone data, flow-based models, or hydrochemical parameters; and (5) Ethical and data management concerns, including privacy risks for small communities, mitigated through data de-identification and tiered reporting platforms. To address these challenges, we propose an integrated framework that features adaptive sampling networks, multi-scale wastewater sample banks, biomarker databases with multidimensional metadata, and intelligent data dashboards. In summary, wastewater-based epidemiology offers unparalleled scalability for equitable health surveillance and can improve the health of the entire population by providing timely and objective information to guide the development of targeted policies.

Three-dimensional ordered porous carbon materials exhibit potential application prospects as excellent drug supports in drug delivery systems due to their high specific surface area, tunable pore structure, and excellent biocompatibility. In this study, three-dimensional ordered porous carbon materials were prepared using Acanthopanax senticosus herbal residues as raw material and KOH as activating agent through a one-step pyrolysis method. The prepared carbon-based material was systematically characterized by powder X-ray diffraction, scanning electron microscopy, N₂ adsorption-desorption and Fourier-transform infrared spectroscopy. The results show that the three-dimensional ordered porous carbon materials prepared with KOH as the activator via pyrolysis possess abundant functional groups, high porosity, and high specific surface area, with a specific surface area of 1 471.6 m²·g^-1. The three-dimensional ordered porous carbon materials prepared at 800 ℃ exhibits a high drug loading capacity (78.0%) and drug release rate (86.8%) for 5-fluorouracil. Three-dimensional orderly porous carbon materials show significant application advantages in drug construction, and their high specific surface area and adjustable pore size structure significantly improve the drug load rate and drug release rate, providing a solid foundation for the development of efficient and accurate drug delivery system.

Objective To summarize the epidemiological and clinical features of infectious diseases of the central nervous system(CNS)by a single-center analysis.Methods A retrospective analysis was conducted on the data of 1247 cases of CNS infectious diseases diagnosed and treated in the First Medical Center of PLA General Hospital from 2001 to 2020.Results The data for this group of CNS infectious diseases by disease type in descending order of number of cases were viruses 743(59.6％),Mycobacterium tuberculosis 249(20.0％),other bacteria 150(12.0％),fungi 68(5.5％),parasites 18(1.4％),Treponema pallidum 18(1.4％)and rickettsia 1(0.1％).The number of cases increased by 177 cases(33.1％)in the latter 10 years compared to the previous 10 years(P<0.05).No significant difference in seasonal distribution pattern of data between disease types(P>0.05).Male to female ratio is 1.87︰1,mostly under 60 years of age.Viruses are more likely to infect students,most often at university/college level and above,farmers are overrepresented among bacteria and Mycobacterium tuberculosis,and more infections of Treponema pallidum in workers.CNS infectious diseases are characterized by fever,headache and signs of meningeal irritation,with the adductor nerve being the more commonly involved cranial nerve.Matagenomic next-generation sequencing improves clinical diagnostic capabilities.The median hospital days for CNS infectious diseases are 18.00(11.00,27.00)and median hospital costs are ￥29,500(￥16,000,￥59,200).The mortality rate from CNS infectious diseases is 1.6％.Conclusions The incidence of CNS infectious diseases is increasing last ten years,with complex clinical presentation,severe symptoms and poor prognosis.Early and accurate diagnosis and standardized clinical treatment can significantly reduce the morbidity and mortality rate and ease the burden of disease.

Objective To compare the clinical efficacy of intraoperative slide rail CT combined with C-arm X-ray assis-tance and just C-arm for percutaneous screw in the treatment of pelvic posterior ring injury.Methods A retrospective analysis was performed on the patient data of 76 patients with posterior pelvic ring injury admitted to the Department of Orthopedic Trauma from December 2018 to February 2022.Among them,39 patients in the CT group were treated with C-arm combined with slide rail CT-assisted inline fixation including 23 males and 16 females with an average age of(44.98±7.33)years old;and the other 37 patients in the C-arm group were treated with intraline fixation treatment under only C-arm fluoroscopy in-cluding 24 males and 13 females with an average age of(44.37±10.82)years old.Among them,42 patients with anterior ring fractures were treated with percutaneous inferior iliac spines with internal fixation(INFIX)or suprapubic support screws to fix the anterior pelvic ring.Postoperative follow-up time,operation time,complications of the two groups were compared.Results of Matta reduction criteria,Majed efficacy evaluation,the CT grading and the rate of secondary surgical revision were com-pared.Results The nailing time of(32.63±7.33)min in CT group was shorter than that of(52.95±10.64)min in C-arm group(t=-9.739,P＜0.05).The follow-up time between CT group(11.97±1.86)months and C-arm group(12.03±1.71)months were not statistically significant(P＞0.05).The postoperative complication rates between two groups were not statistically significant(x2=0.159,P＞0.05).Results of Matta reduction criteria(Z=2.79,P＜0.05),Majeed efficacy evaluation(Z=2.79,P＜0.05),CT grading(Z=2.83,P＜0.05)in CT group were better than those in C-arm group(P＜0.05);the secondary surgical revision rate in the CT group was significantly lower than that in the C-arm group(x2=5.641,P＜0.05).Conclusion Compared with traditional C-arm fluoroscopy,intraoperative slide rail CT combined with C-arm assisted percutaneous sacroiliac joint screw placement surgery has the characteristics of short operation time,high accuracy and safety,and significant decrease in postoperative sec-ondary revision rate,and is one of the effective methods for re-establishing the stability of the posterior ring of pelvic fracture.

BACKGROUND: Patients with atrial fibrillation (AF) and prior stroke history have a high risk of cardiovascular events despite anticoagulation therapy. It is unclear whether catheter ablation (CA) has further benefits in these patients. METHODS: AF patients with a previous history of stroke or systemic embolism (SE) from the prospective Chinese Atrial Fibrillation Registry study between August 2011 and December 2020 were included in the analysis. Patients were matched in a 1:1 ratio to CA or medical treatment (MT) based on propensity score. The primary outcome was a composite of all-cause death or ischemic stroke (IS)/SE. RESULTS: During a total of 4.1 ± 2.3 years of follow-up, the primary outcome occurred in 111 patients in the CA group (3.3 per 100 person-years) and in 229 patients in the MT group (5.7 per 100 person-years). The CA group had a lower risk of the primary outcome compared to the MT group [hazard ratio (HR) = 0.59, 95% CI: 0.47-0.74, P < 0.001]. There was a significant decreasing risk of all-cause mortality (HR = 0.43, 95% CI: 0.31-0.61, P < 0.001), IS/SE (HR = 0.73, 95% CI: 0.54-0.97, P = 0.033), cardiovascular mortality (HR = 0.32, 95% CI: 0.19-0.54, P < 0.001) and AF recurrence (HR = 0.33, 95% CI: 0.30-0.37, P < 0.001) in the CA group compared to that in the MT group. Sensitivity analysis generated consistent results when adjusting for time-dependent usage of anticoagulants. CONCLUSIONS In AF patients with a prior stroke history, CA was associated with a lower combined risk of all-cause death or IS/SE. Further clinical trials are warranted to confirm the benefits of CA in these patients.

Aim To study the therapeutic effect of Balanophora polysaccharide(BPS)on gastric ulcer(GU)induced by acetic acid in rats and to investigateits mechanisms. Methods Sixty male SD rats were randomly divided into sham-operated group, GU model group, omeprazole positive group(3.6 mg·kg-1), and low, medium and high dose of BPS treatment groups(100, 200 and 400 mg·kg-1). The GU model group was prepared by acetic acid cautery method, and the morphology and pathological changes of ulcers were observed by visual observation combined with HE staining, and the ulcer area and inhibition rate were measured and calculated; superoxide dismutase(SOD)activity, malondialdehyde(MDA)content and glutathione peroxidase(GSH-PX)activity were measured by enzymatic assay; tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)content were detected by ELISA. The expression levels of epidermal growth factor(EGF)and epidermal growth factor receptor(EGFR)were measured by immunohistochemistry staining and Western blot. Results Compared with the sham-operated group, obvious ulcer damage was seen in the model group. Compared with the model group, the BPS-treated group showed a significant reduction in ulcer area, an increase in SOD and GSH-PX activity and EGF and EGFR expression levels, and a significant decrease in MDA, TNF-α and IL-6 content. Conclusions BPS has a therapeutic effect on GU in rats, and its mechanism may be related to the inhibition of oxidative stress, suppression of inflammatory stimuli and promotion of regenerative repair of gastric mucosa.

Objective To study whether bergapten (BG) protects PC12 cells from oxygen-glucose deprivation (OGD) induced cell injury by regulating long non-coding RNA (lncRNA) opioid receptor gene (Oprm1) expression. Methods PC12 cells were divided into control (Con) group, OGD group, OGD+ low concentration BG (BG-L) group, OGD+medium concentration BG (BG-M) group, OGD + high concentration BG (BG-H) group, OGD + pcDNA group, OGD+pcDNA-Oprm1 group, OGD+BG+si-NC group, OGD+BG+si-Oprm1 group. The malondialdehyde (MDA) content, superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities were measured by the kits. Cell apoptosis rate was analysed by flow cytometry. The expression level of Oprm1 was analysed by Real-time PCR. Results Compared with the Con group, the apoptosis rate and MDA content of PC12 cells in OGD group increased significantly, whereas Oprm1 expression, SOD and GSH-Px activity decreased significantly (P < 0. 05). Compared with the OGD group, the apoptosis rate and MDA content of PC12 cells in the OGD + BG-L group, OGD + BG-M group, OGD + BG-H group were significantly reduced, whereas the Oprm1 expression, SOD and GSH-Px activities increased significantly (P < 0. 05). Compared with the OGD+pcDNA group, the apoptosis rate and MDA content of the PC12 cells in the OGD+pcDNA-Oprm1 group reduced significantly, whereas the SOD and GSH-Px activities increased significantly (P<0. 05). Compared with the OGD+BG+si-NC group, the apoptosis rate and MDA content of PC12 cells in the OGD+BG+si-Oprm1 group increased significantly, whereas the SOD and GSH-Px activities decreased significantly (P < 0. 05). Conclusion Bergapten may alleviate OGD-induced PC12 cell injury, which is correlated to the up-regulation of lncRNA Oprm1 expression.

Objective:To investigate the effect of early postoperative enteral nutrition(EN)on postoperative rehabilitation and inflammation after laparoscopic radical gastrectomy for gastric cancer,in order to provide reference for postoperative rehabilitation of such patients.Methods:Patients who received laparoscopic assisted radical gastrectomy in Department of Gastrointestinal Surgery of The First Affiliated Hospital of Bengbu Medical College from January 2020 to December 2022 were included in the analysis.According to the different ways of postoperative nutritional treatment,patients were divided into the observation group(early postoperative EN group)and the control group(parenteral nutrition group),and indexes such as postoperative rehabilitation,abdominal drainage flow and the level of inflammatory mediators in drainage fluid were compared between the two groups.Results:A total of 81 patients were included,including 41 in the observation group and 40 in the control group.Interval of the first postoperative exhaust(t=3.806;P＜0.001)and resuming diet day(t=5.510;P＜0.001),and length of postoperative hospital stay(t=2.401;P=0.019)in the observation group were shorter than those in the control group.Levels of peripheral blood albumin(t=14.040;P＜0.001)and prealbumin(t=9.832;P＜0.001)of the observation group at postoperative day(POD)5 were significantly higher than those of the control group,but there was no significant difference in hemoglobin level(t=1.477;P=0.144).The level of CRP in peripheral blood of the observation group at POD 5(t=7.758;P＜0.001)and the incidence of postoperative SIRS[(12.2％,5/41)vs(32.5％,13/40),x2=4.830;P=0.028)]were significantly lower than those in the control group.The average drainage volume(t=6.858;P＜0.001),drainage removal time(t=5.016;P＜0.001),and TNF-α level(t=4.993;P＜0.001)and IL-6 level(t=20.640;P＜0.001)in postoperative drainage at POD 5 were significantly lower in the observation group than those in the control group.Conclusion:Early postoperative EN could accelerate the rehabilitation process after laparoscopic radical gastrectomy,improve postoperative nutritional status,and reduce abdominal inflammation.

OBJECTIVE: To investigate the causes of ineffectiveness of platelet transfusion with monoclonal antibody solid phase platelet antibody test (MASPAT) matching in patients with allogeneic hematopoietic stem cell transplantation and explore the strategies of platelet transfusion. METHODS: A case of donor-specific HLA antibodies (DSA) induced by transfusion which ultimately resulted in transplantation failure and ineffective platelet transfusion with MASPAT matching was selected, and the causes of ineffective platelet transfusion and platelet transfusion strategy were retrospectively analyzed. RESULTS: The 32-year-old female patient was diagnosed as acute myeloid leukemia (high risk) in another hospital with the main symptoms of fever and leukopenia, who should be admitted for hematopoietic stem cell transplantation after remission by chemotherapy. In the course of chemotherapy, DSA was generated due to platelet transfusion, and had HLA gene loci incompatible with the donor of the first transplant, leading to the failure of the first transplant. The patient received platelet transfusion for several times before and after transplantation, and the results showed that the effective rate of MASPAT matched platelet transfusion was only 35.3%. Further analysis showed that the reason for the ineffective platelet transfusion was due to the missed detection of antibodies by MASPAT method. During the second hematopoietic stem cell transplantation, the DSA-negative donor was selected, and the matching platelets but ineffective transfusion during the primary transplantation were avoided. Finally, the patient was successfully transplanted and discharged from hospital. CONCLUSIONS DSA can cause graft failure or render the graft ineffective. For the platelet transfusion of patients with DSA, the platelet transfusion strategy with matching type only using MASPAT method will miss the detection of antibodies, resulting in invalid platelet transfusion.
