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.

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.

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.

Objective:To investigate the distribution of pathological types of unilateral primary aldosteronism, and to explore the clinical characteristics and prognosis of patients with different pathological types.Methods:A total of 241 patients with unilateral primary aldosteronism who underwent adrenal surgery were included in this study. The clinical data and postoperative follow-up data were collected, and the postoperative tissue sections were stained with HE and aldosterone synthase. According to the staining results, pathological types of 241 patients were classified, and the clinical characteristics and surgical prognosis of patients with unilateral primary aldosteronism were compared.Results:According to the international histopathology consensus for unilateral primary aldosteronism, among 241 patients with unilateral primary aldosteronism, 223 were classical(92.5%), 17 were non-classical(7.1%), and 1 was aldosterone producing carcinoma(0.4%). Among classical cases, 189 were aldosterone producing adenoma and 34 were aldosterone producing nodule. In the non-classical cases, 8 cases were multiple aldosterone producing nodule and 9 cases were multiple aldosterone producing nodule. Compared with the classical group, the non-classical group had a longer duration of hypertension(9.0 vs 5.0 years, P=0.062) and a lower baseline plasma aldosterone concentration(273 vs 305 pg/mL, P=0.147), but the difference was not significant. There was no significant difference between the two groups in the proportion of patients who achieved a complete biochemical response after surgery(98% vs 92.3%, P=0.281), but the proportion of patients who achieved a complete clinical response was significantly lower in the non-classical group(23.1% vs 52.9%, P=0.046). Conclusion:The pathological types of unilateral primary aldosteronism are predominantly classical, with aldosterone-producing adenoma being the most common. There were no significant differences in the clinical characteristics and postoperative biochemical remission rates between classical and non-classical patients, but the clinical prognosis of the latter was inferior to the former.

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.

Using constructivism theory, this study explored the relationship between the "origin" and "flow" of academic schools in traditional Chinese medicine (TCM), clarified the developmental patterns of schools, and provided insights for the modernization, inheritance, and innovation of current schools. Academic schools originate from different cultural sources, and their differentiation and development are similar to the replication, spread and variation of biological "genes". The theoretical characteristics of constructivism align well with the principles of formation and differentiation of academic schools. The construction of academic thoughts and core diagnostic and therapeutic concepts within each school can be seen as a multilevel unity of self-construction, mutual construction among individuals, and social construction. Firstly, individual medical practitioners choose and inherit from the origins of TCM, integrating personalized understanding, which then differentiates into various schools in the history of academia. Secondly, during the process of cultural inheritance, medical practitioners from different times and regions gradually form academic schools and local medical schools through the method of "tailoring strategies to three categories of etiological factors" and mutual construction among individuals. Finally, in the context of the scientific, standardized, and intelligent development of modern medicine, the further evolution of academic schools needs to follow the evolutionary laws of traditional medicine, combine with the health needs of the new era, adopt a social construction approach, facilitate multi-party participation in the inheritance and innovation of academic thoughts and clinical experiences, and utilize the internet and intelligent technology means to empower modern development.

Objective:To comprehensively evaluate the effectiveness of preventive measures for acute kidney injury (AKI) in children and identify the effective strategies.Methods:Databases were systematically searched including CNKI, Wanfang, VIP, China Biology Medicine National Knowledge Infrastructure, PubMed, Embase, Cochrane Library databases, and the reference lists of relevant papers for randomized controlled trials on preventing pediatric AKI up to December 2023. Literature screening was conducted based on the inclusion and exclusion criteria, followed by data extraction and quality assessment of included studies. Traditional and network meta-analyses were performed, along with trial sequential analysis (TSA).Results:A total of 21 studies involving 3 483 children were included. Traditional and network meta-analysis showed that dexmedetomidine was effective in preventing AKI in children undergoing cardiac surgery or cardiac angiography ( OR=0.26, 0.27; 95% CI 0.11-0.64, 0.13-0.58). Remote ischemic preconditioning (RIPC) was effective in preventing AKI in children after cardiac surgery ( OR=0.43, 0.44; 95% CI 0.24-0.79, 0.23-0.83). Traditional and network meta-analysis specific to children with sepsis or septic shock showed that balanced solution was effective in preventing pediatric AKI ( OR=0.58, 0.52; 95% CI 0.42-0.79, 0.37-0.73). TSA indicated that the total sample sizes of dexmedetomidine (348 cases) and RIPC (666 cases) both reached the required information size (320 and 534 cases); additionally, the Z-curve for balanced solution (cumulative Z=3.38) crossed the TSA monitoring boundary ( Z=3.29). Conclusion:Dexmedetomidine reduces the risk of AKI in children undergoing cardiac surgery or cardiac angiography, RIPC decreases the risk of AKI in children after cardiac surgery, and balanced solution lowers the risk of AKI in children with sepsis or septic shock.
