Avian coccidiosis, an acute parasitic disease that mainly harms chicks, is widely prevalent across the world, which poses a serious threat to poultry industry. Because of the single prophylactic formulations, veterinary clinical treatment of coccidiosis mainly relies on chemically synthesized agents, polyether ionophores and Chinese herbal medicines. The introduction of novel anticoccidial drugs is slow for a long period of time, and there is an increasing problem of anticoccidial drug resistance following long-term use, which has become an urgent problem to be solved in poultry industry. This review summarizes the levels of anticoccidial drug resistance across China from 2018 to 2023, and analyzes the resistance to various anticoccidial agents in coccidia. It is indicated that the overall prevalence of anticoccidial drug resistance is high in coccidia, and development of novel anticoccidial agents and products with reduced antibiotics use and alternatives of antibiotics is of an urgent need.

ObjectiveTo investigate the effects of Dihuang Yinzi on the cognitive function in the mouse model of learning and memory impairments induced by scopolamine (SCOP) and explore the treatment mechanism. MethodsA mouse model of learning and memory impairment was induced by intraperitoneal injection of SCOP. Sixty male C57BL/6J mice were randomized into six groups: control (0.9% NaCl, n=10), model (SCOP 1 mg·kg-1·d-1, n=10), low-, medium-, and high-dose Dihuang Yinzi (SCOP 1 mg·kg-1·d-1 + Dihuang Yinzi 5.5, 11.0, and 22.0 g·kg-1·d-1, n=10), and donepezil (SCOP 1 mg·kg-1·d-1 + donepezil 0.84 mg·kg-1·d-1, n=10). Mice were administrated with corresponding drugs for 6 weeks. Modeling started in the 4th week, and mice in other groups except the control group were injected with SCOP intraperitoneally 40 min after daily gavage. Behavioral testing began in the 5th week, 30 min after modeling each day. The Morris water maze and novel object recognition tests were carried out to evaluate the spatial learning and memory function of mice. Nissl staining was employed to observe the survival of neurons and Nissl bodies in the hippocampal CA1 region. Western blot was employed to determine the protein levels of silent information regulator 2 (SIRT2), α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptor 1 (GluA1), protein kinase A (PKA), cAMP response element-binding protein (CREB), phosphorylated-CREB (p-CREB), postsynaptic density protein 95 (PSD95), growth-associated protein-43 (GAP-43), and synaptophysin (SYN) in the hippocampus. Immunofluorescence was used to detect the expression of doublecortin (DCX) in the hippocampal dentate gyrus (DG) region. ResultsCompared with the control group, the model group showed impaired learning and memory (P<0.01), obvious neuronal damage in the hippocampal CA1 region, a reduction in neuron survival (P<0.01), a decrease in DCX expression in the hippocampal DG region (P<0.01), down-regulated proteins levels of GluA1, PKA, p-CREB/CREB, PSD95, SYN, and GAP-43 in the hippocampal tissue (P<0.05, P<0.01), and an up-regulated protein level of SIRT2 (P<0.01). Compared with the model group, the medium- and high-dose Dihuang Yinzi groups and the donepezil group showed improvements in learning and memory (P<0.05, P<0.01), while the low-, medium-, and high-dose Dihuang Yinzi groups and the donepezil group had increased neuron survival (P<0.05, P<0.01). The medium-dose Dihuang Yinzi group and the donepezil group showed increased DCX expression (P<0.05, P<0.01). The medium- and high-dose Dihuang Yinzi groups and the donepezil group showed up-regulation in the protein levels of GluA1, PKA, p-CREB/CREB, PSD95, SYN, and GAP-43 (P<0.05, P<0.01) and down-regulation in the protein level of SIRT2 (P<0.01). ConclusionDihuang Yinzi can improve the cognitive function in the mouse model of learning and memory impairments induced by SCOP by inhibiting the upregulation of SIRT2, activating the PKA/CREB signaling pathway, improving synaptic plasticity, and reducing hippocampal neuronal damage.

The Inner Canon of Yellow Emperor (《黄帝内经》) constructs its theoretical system under the influence of the holistic, symbolic, and holographic mental models of traditional Chinese medicine (TCM). It lays the theoretical foundation of TCM and provides a paradigm for TCM theory construction, serving as an original academic gene and theoretical source for the inheritance and innovation of modern TCM. Based on the theoretical paradigms derived from The Inner Canon of Yellow Emperor, the holistic mental model, the symbolic mental model, and the holographic mental model in shaping nature-human medicine theory, imagery-based theory, and fractal theory, this study revealed that TCM theory relies on the cognitive framework of traditional cultural mental models. On this basis, we proposed that the modern TCM mental model should return to its roots while fostering innovation, integrating tradition with modernity by combining macroscopic with microscopic perspectives, scientific with humanistic cognition, as well as evidence-based research with digital and artificial intelligence technologies. Furthermore, with a future-oriented approach, this paper discussed on the strategies for reshaping the modern TCM mental model from three dimensions of TCM diagnosis and treatment, TCM education, and TCM research, which could not only preserve the traditional clinical thinking characteristics of TCM, but also innovate modern TCM practice.

Traumatic brain injury (TBI) can cause a series of secondary changes, such as neuronal dysfunction, blood-brain barrier destruction, secondary neurovascular injury, neuroinflammation, and even neurodegenerative diseases. In recent years, studies have found that microglia can regulate the long-term inflammation and tissue repair process after TBI through the changes of M1 phenotype and M2 phenotype, affecting the TBI progress. Therefore, this article reviews the recent advance in role of microglia, regulatory mechanisms and related therapies of microglia after TBI, in order to provide some references for TBI treatment.

Objective:To document any effect of a pulsed electromagnetic field (PEMF) on the regulation of neuropeptide Y (NPY) in nucleus pulposus (NP) tissue, NP cell apoptosis and matrix degradation using rats with intervertebral disc degeneration (IDD).Methods:Eighteen Sprague-Dawley rats were randomly divided into a control group, an IDD model group (the model group), and a PEMF group. IDD was induced in both the model and PEMF groups. Right after the modeling, the PEMF group received 14 days of PEMF treatment, while the control group and model group were given no special treatment. Meanwhile, the primary rat nucleus pulposus cells (NPCs) were cultured using Dulbecco′s Modified Eagle Medium at 37℃ and 5% CO 2. When the fusion rate reached 90% after passage, the NPCs were divided into a control group, a TNF-α model group (referred to as model group) and TNF-α + PEMF group (referred to as PEMF group) and treated accordingly. Eight weeks after the modeling, safranin-o/fast green staining was used to assess any pathological morphology changes. The expression of NPY, neuropeptide Y receptor Y2 (NPY2R), bcl-2-associated X protein (Bax), B-cell lymphoma 2 (Bcl-2), collagen type II (Col-II) and matrix metalloproteinase-3 (MMP3) in the intervertebral disc and the cultivated nucleus pulposus cells of the 3 groups were determined. Results:The intervertebral disc cells in the model group were ruptured and folded, with significantly increased polysaccharide and protein components, and significantly increased bone fibers. In the PEMF group the cell boundaries were clearer, with less fibrin fracture and increased cartilage tissue. NPY was expressed in the fibrous annulus and the nucleus pulposus of the intervertebral disc in the model group. The average expression levels of NPY and NPY2R were significantly higher than in the control group and the model group. Compared with the control group, there was a significant increase in the level of Bax and a significant decrease in the expression of Bcl-2 in the model group, and there was a significant decrease in the level of Bax in the PEMF group. Compared with the control group, there was a significant decrease in the Col-II level but a significant increase in the MMP3 protein expression in the model group. The average Col-II mRNA expression was significantly higher in the PEMF group compared with the model group, but the average MMP3 protein expression was significantly less. Those results are consistent with observations in vivo.Conclusion:PEMF may reverse the imbalance of ECM metabolism and delay IDD degeneration by up-regulating the expression of NPY and Bcl-2, as well as blocking the Bax/Bcl-2 signaling pathway to inhibit apoptosis of nucleus pulposus cells.

Objective:To compare the efficacy and safety of low-dose and standard-dose radiotherapy (LD-RT vs. SD-RT) in the treatment of oropharyngeal cancer patients with positive human papillomavirus (HPV). Methods:All comparative studies of low-dose versus standard-dose radiotherapy in the treatment of HPV-positive oropharyngeal cancer were searched from PubMed, Web of Science, Cochrane Library, EMbase, Chinese Biomedical Literature Database (CBM), CNKI, Chongqing VIP, and Wanfang databases from January 1, 2000 to February 9, 2023. According to the inclusion and exclusion criteria, the data were strictly screened, and the RevMan 5.4 software was used for meta-analysis.Results:A total of 8 studies were included. The pooled results showed that the overall survival (OS) and progression-free survival (PFS) of patients in the LD-RT group were similar to those in the SD-RT group ( HR=0.83, 95% CI=0.59-1.18, P=0.31; HR=0.97, 95% CI=0.53-1.78, P=0.92), but the rate of percutaneous endoscopic gastrostomy (PEG) insertion was significantly reduced ( RR=0.45, 95% CI=0.28-0.72, P=0.001). Conclusion:LD-RT yields similar efficacy and lower rate of PEG insertion compared with SD-RT in HPV-positive oropharyngeal neoplasm patients.

ObjectiveTo observe the possible mechanism of Dihuang Yinzi Decoction (地黄饮子) for improving cognitive dysfunction in Alzheimer's disease (AD) from the perspective of retina. MethodsForty-five APP/PS1 mice (AD model mice) were randomly divided into model group, Dihuang Yinzi Decoction group, and memantine group, with 15 mice in each group, while 15 wild-type C57BL/6J mice from the same litter were used as blank group. Mice in Dihuang Yinzi Decoction group were given Dihuang Yinzi Decoction 30.03 g/(kg·d) by gavage, mice in the memantine group were given memantine hydrochloride 6.1 mg/(kg·d) by gavage, and mice in the blank group and the model group were given normal saline 2 ml/(kg·d) by gavage for 4 consecutive weeks. Fasting blood glucose was measured weekly. After 4 weeks of intervention, oral glucose tolerance test (OGTT) and insulin tolerance test (ITT) were performed; Morris water maze was used to detect the changes in spatial memory ability of mice; glucose oxidase method was used to detect retinal glucose content of mice; enzyme-linked immunosorbent assay (ELISA) was used to detect serum and retinal insulin content of mice, and Homeostatic Model Assessment of insulin resistance (HOMA-IR) was calculated. Hematoxylin-eosin (HE) staining was performed to observe the histopathological changes in the retina, and the retinal thickness and ganglion cell number were counted; protein immunoblotting was performed to detect the retinal pathway-associated proteins [insulin receptor substrate 1 (IRS1), phosphorylated insulin receptor substrate 1 (pIRS1), phosphatidylinositol-3-hydroxykinase (PI3K), protein kinase B (Akt1), phosphorylated protein kinase B (pAkt1)] expression; retinal glucose transporter protein 4 (GLUT4) expression was detected by immunohistochemistry. ResultsCompared with the blank group, fasting blood glucose of mice in the model group at weeks 1, 2, 3, and 4, blood glucose and area under the curve (AUC) at different time point of OGTT and ITT test, fasting serum insulin, and HOMA-IR increased (P<0.05, P<0.01); in the Morris water maze experiment, the escape latency increased from day 3 to day 5, and the number of crossing platforms, the percentage of target quadrant distance, and the percentage of target quadrant time decreased (P<0.05, P<0.01); the outer nuclear layer of the retina became sparse, thinner, and the number of ganglion cells decreases (P<0.01); the expression level of retinal glucose increased, while the expression levels of insulin, pIRS1/IRS1, PI3K/β-Actin, pAkt1/Akt1, and GLUT4 proteins decreased (P<0.01). Compared with the model group, fasting blood glucose at week 4, blood glucose at each time point of the OGTT and ITT tests AUC decreased (P<0.05, P<0.01), and fasting serum insulin and HOMA-IR decreased (P<0.05) in Dihuang Yinzi Decoction group; In the Morris water maze test, the escape latency shortened on day 4 and day 5, number of platform crossings, target quadrant distance as a proportion of total distance, and target quadrant movement time as a proportion of total time decreased (P<0.05, P<0.01); retinal pathological changes alleviated, and retinal thickness and ganglion cell number increased (P<0.01); retinal glucose content decreased, and retinal pIRS1/IRS1, PI3K/β-Actin, and GLUT4 protein expression elevated (P<0.05 or P<0.01). ConclusionsDihuang Yinzi Decoction can improve cognitive dysfunction of Alzheimer's disease, which may be related to regulating retinal insulin content and insulin signaling pathway.

Objectives:To investigate the safety and efficacy of concomitant mitral valvuloplasty(MVP)and implantation of domestic third-generation magnetically levitated Corheart 6 left ventricular assist device(LVAD). Methods:Clinical data of 13 end-stage heart failure patients who underwent Corheart 6 LVAD implantation and MVP at Central China Fuwai Hospital of Zhengzhou University from October 2021 to March 2023 were retrospectively analyzed.Mortality and complication events during hospitalization and at follow-up were collected,and changes in myocardial injury biomarkers,renal function,hemodynamics,and echocardiographic indices were observed. Results:There were no perioperative deaths and no MVP-related complications in these patients.During a mean follow-up of(14.2±5.6)months,2 patients died due to COVID-19 pneumonia and cardiac arrest respectively,11 cases(84.6%)survived.There were no recurrences of moderate-to-severe mitral regurgitation in the survived patients.Compared with preoperative value,higher cardiac output,lower central venous pressure,pulmonary artery systolic pressure(PASP),and mean pulmonary artery pressure(PAMP)were evidenced at 24 h and 72 h postoperatively,estimated glomerular filtration rate was also reduced at 1 week post operation(all P<0.010).High-sensitive troponin T level was significantly increased at 1 week post operation and then reduced at 1 month post operation,but still not returned to pre-operative level([125.5±281.9]pg/ml at baseline,[1 295.6±654.6]pg/ml at 1 week post operation and[278.0±300.5]pg/ml at 1 month post operation).Echocardiography showed that compared with preoperative period,the left ventricular ejection fraction tended to be higher at 1 and 6 months postoperatively(both P>0.017),whereas left ventricular end-diastolic dimension,PASP,and PAMP were significantly reduced(all P<0.010). Conclusions:Domestic third-generation magnetically levitated Corheart 6 LVAD implantation with concomitant MVP is safe and feasible,there is no recurrence of moderate-to-severe mitral regurgitation,a significant reduction in pulmonary artery pressure,and significant hemodynamic improvement in early to mid-term postoperatively are observed in survived patients.
