Asarum forbesii is a perennial herb born in a shaded and humid environment, which is warm in nature. With the efficacy of warming lung, resolving fluid retention, and relieving coughs, it can be used to treat the syndrome of cold fluid accumulating in lung. To investigate the effects of different shading conditions on the composition and efficacy of A. forbesii, this study planted A. forbesii under 20% natural light(NL20), 40% natural light(NL40), 60% natural light(NL60), and 80% natural light(NL80) and utilized ultra performance liquid chromatography(UPLC) and micro broth 2-fold dilution method to detect the volatile chemical compounds and the minimum inhibitory concentration. At the same time, the study investigated the effects of A. forbesii grown under different shading conditions on the signs, pathological changes of lung tissues, serum cytokine levels, activities of mitochondrial respiratory chain complexes Ⅰ-Ⅴ in lung tissues, and relative expression of related genes of mice with syndrome of cold fluid accumulating in lung. The results indicated that with the increase of shading, the content of kakuol, methyl eugenol, and asarinin in A. forbesii and the antibacterial effect showed a tendency of increasing first and then decreasing, and the NL40 group was significantly better than the other groups. Under the conditions of NL20 and NL40, A. forbesii significantly alleviated the pathological damage to lung tissues, restored the homeostasis of the lung, and enhanced the energy metabolism level of mice with syndrome of cold fluid accumulating in lung. In addition, A. forbesii planted under the two conditions reduced the content of interleukin-8(IL-8), interleukin-13(IL-13), tumor necrosis factor-α(TNF-α), and mucin 5AC(MUC5AC), increased the levels of interleukin-10(IL-10) and aquaporin 1(AQP1), lowered the expression of MMP9, VEGF, TGF-β, and MAPK3. In conclusion, the therapeutic effect of A. forbesii on the syndrome of cold fluid accumulating in lung was positively correlated with the degree of shading, and the chemical composition and efficacy of warming lung and resolving fluid retention were optimal under the conditions of NL20-NL40. This study can provide reference for the pharmacological research and cultivation of A. forbesii.

Tauopathies, including Alzheimer's disease (AD), are a series of neurodegenerative diseases characterized by pathological accumulation of the microtubule-associated protein tau. Since the abnormal modification and deposition of tau in nerve cells are crucial for tauopathy etiology, methods for reducing tau levels, such as promoting tau degradation, may become effective strategies for disease treatment. Herein, we identified that sorafenib significantly reduced total tau and phosphorylated tau levels through screening FDA-approved drugs. We showed that sorafenib treatment attenuated cognitive deficits and tau pathologies in PS19 tauopathy model mice. Mechanistically, we found that sorafenib inhibited multiple kinases involved in tau phosphorylation and promoted autophagy. Importantly, we further demonstrated that sorafenib also promoted the expression of the E3 ubiquitin ligase FBXW7, which could bind tau and mediate tau degradation through the ubiquitin-proteasome pathway. Finally, we showed that FBXW7 expression decreased in the brains of AD patients and tauopathy model mice, and that overexpression of FBXW7 in the hippocampus attenuated cognitive deficits and tau pathologies in PS19 mice. These results suggest that sorafenib may be a promising treatment option for tauopathies by promoting tau degradation and reducing tau phosphorylation, and that targeting FBXW7 could also serve as an alternative therapeutic strategy for tauopathies.

With the growing emphasis on maternal and child oral health, the significance of managing oral health across preconception, pregnancy, and infancy stages has become increasingly apparent. Oral health challenges extend beyond affecting maternal well-being, exerting profound influences on fetal and neonatal oral development as well as immune system maturation. This expert consensus paper, developed using a modified Delphi method, reviews current research and provides recommendations on maternal and child oral health management. It underscores the critical role of comprehensive oral assessments prior to conception, diligent oral health management throughout pregnancy, and meticulous oral hygiene practices during infancy. Effective strategies should be seamlessly integrated across the life course, encompassing preconception oral assessments, systematic dental care during pregnancy, and routine infant oral hygiene. Collaborative efforts among pediatric dentists, maternal and child health workers, and obstetricians are crucial to improving outcomes and fostering clinical research, contributing to evidence-based health management strategies.

Further evidence is needed to explore the impact of high-altitude environments on the neurologic function of neonates.Non-invasive techniques such as cerebral near-infrared spectroscopy and amplitude-integrated electroencephalography can provide data on cerebral oxygenation and brain electrical activity.This study will conduct multiple cerebral near-infrared spectroscopy and amplitude-integrated electroencephalography monitoring sessions at various time points within the first 3 days postpartum for healthy full-term neonates at different altitudes.The obtained data on cerebral oxygenation and brain electrical activity will be compared between different altitudes,and corresponding reference ranges will be established.The study involves 6 participating centers in the Chinese High Altitude Neonatal Medicine Alliance,with altitude gradients divided into 4 categories:800 m,1 900 m,2 400 m,and 3 500 m,with an anticipated sample size of 170 neonates per altitude gradient.This multicenter prospective cohort study aims to provide evidence supporting the impact of high-altitude environments on early brain function and metabolism in neonates.[Chinese Journal of Contemporary Pediatrics,2024,26(4):403-409]

Cervical spondylotic radiculopathy(CSR)is a condition caused by the degeneration of cervical intervertebral discs and facet joints,primarily manifesting as the pain,sensory abnormalities,and motor dysfunction in the cervical nerve innervation area of neck,shoulder,and upper limb.For the treatment of CSR,tendon-bone syndrome differentiation in traditional Chinese medicine often faces the issues of conceptual confusion and non-standard syndrome differentiation.Based on the traditional tendon-bone syndrome differentiation and by integrating modern anatomical insights,Professor LIN Ding-Kun,an esteemed scholar of Traditional Chinese Medicine,proposed a classification system for the cervical spine that includes the categories of tendons,joints,bones and marrow.This paper explored the thoughts of Professor LIN for the tendon-bone syndrome differentiation of CSR,summarized the targets of manual therapy,and proposed the four kinds of pathological changes such as tendon overstrain,joint dislocation,bone lesion,and marrow injury,as well as the four techniques of traditional Chinese medicine manipulations,i.e.relaxation of tendons,reduction of joints,protection of marrow,and treatment of bones.The aim is to improve the syndrome-differentiation and treatment for CSR with orthopedic and traumatologic manipulations,and to provide reference for clinical practice.

Objective:To compare the efficacy of amide proton transfer-weighted (APTw) imaging with time-dependent diffusion MRI (td-dMRI) in the diagnosis of malignant breast lesions.Methods:This study was a cross-sectional study. The clinical, pathological and imaging data of patients with breast lesions admitted to the First Affiliated Hospital of Zhengzhou University from March to August 2023 were prospectively analyzed. All patients firstly underwent T 2WI, diffusion-weighted imaging, followed by dynamic contrast-enhanced MRI (DCE-MRI), and finally APTw imaging and td-dMRI were performed for breast lesions using DCE-MRI as reference. Reconstructed images from APTw imaging measured lesions with a frequency shift of 3.5 ppm asymmetric magnetic susceptibility MTR asym(+3.5 ppm). The apparent diffusion coefficient (ADC) values at different oscillating frequency gradients (ADC PGSE, ADC 17 Hz, ADC 33 Hz values) were measured using reconstructed td-dMRI images. Independent sample t-test was used to compare APTw imaging, td-dMRI parameter differences between benign and malignant breast tumors, breast malignant tumors with different molecular types [estrogen receptor (ER) negative and positive, progesterone receptor (PR) negative and positive, human epidermal growth factor receptor (HER-2) negative and positive, proliferation index (Ki-67) low and high expression] and different histological grades (grade Ⅱ and Ⅲ). Receiver operating characteristic curve and area under the curve (AUC) were used to evaluate the efficacy of APTw imaging and td-dMRI parameters in differentiating benign and malignant breast tumors, molecular classification and histological grading of malignant breast lesions. Results:There were 171 lesions in 171 patients, including 103 malignant lesions and 68 benign lesions. Histological grades were grade Ⅱ in 51 cases and grade Ⅲ in 38 cases of 89 cases of invasive carcinoma. Totally 98 cases of malignant lesions were included in molecular typing analysis, 36 cases were ER negative and 62 cases were ER positive. PR was negative in 51 cases and positive in 47 cases. There were 33 negative HER-2 patients, 65 positive HER-2 patients. There were 50 cases of low Ki-67 expression and 48 cases of high Ki-67 expression. The MTR asym(+3.5 ppm) value of malignant breast lesions was higher than that of benign lesions ( t=5.76, P<0.001), and the ADC PGSE, ADC 17 Hz and ADC 33 Hz values were lower than those of benign breast lesions ( t was 4.84, 4.62, 4.01, respectively, all P<0.001). MTR asym(+3.5 ppm) had the highest AUC value (0.83) and the highest specificity (90.38%), and ADC PGSE had the highest sensitivity (85.86%). There were no significant differences in MTR asym(+3.5 ppm), ADC PGSE, ADC 17 Hz and ADC 33 Hz between grade Ⅱ and grade Ⅲ histological grades of malignant breast lesions (all P>0.05). The ADC PGSE value of ER negative was higher than that of ER positive ( t=2.34, P=0.018), and the AUC for distinguishing ER positive from negative was 0.64. The ADC PGSE and ADC 17 Hz values of PR negative were higher than those of PR positive ( t=2.87, 2.81, P=0.004, 0.006, respectively), and their AUCs for identifying PR positive versus negative breast malignant lesions were 0.68 and 0.67, respectively. The ADC 33 Hz value of negative HER-2 was lower than that of positive HER-2 ( t=3.00, P=0.003), and the AUC for distinguishing positive and negative HER-2 was 0.67. There were no significant differences in other parameters among different subtypes of breast malignant lesions (all P>0.05). Conclusion:Compared with td-dMRI, APTw imaging is more effective in differentiating benign and malignant lesions of breast tumors, and ADC values at different gradient oscillation frequencies obtained by td-dMRI show better diagnostic efficacy in differentiating different molecular types of breast malignant lesions.
