Alzheimer's disease (AD), a prototypical neurodegenerative disorder, encompasses multifaceted pathological processes. As pivotal cellular structures within the central nervous system, ion channels play critical roles in regulating neuronal excitability, synaptic transmission, and neurotransmitter release. Extensive research has revealed significant alterations in the expression and function of ion channels in AD, implicating an important role of ion channels in the pathogenesis of abnormal Aβ deposition, neuroinflammation, oxidative stress, and disruptions in calcium homeostasis and neural network functionality. This review systematically summarizes the crucial roles and underlying mechanisms of ion channels in the onset and progression of AD, highlighting how these channel abnormalities contribute to AD pathophysiology. We also discuss the therapeutic potential of ion channel modulation in AD treatment, emphasizing the importance of addressing multifactorial nature and heterogeneity of AD. The development of multi-target drugs and precision therapies is proposed as a future direction of scientific research.

With the improvement of China's socioeconomic status,the issue of aging has become increasingly prominent,making cerebral infarction a common disease among the elderly.In recent years,research on cerebral infarction has gradually deepened,shifting focus from merely protecting and repairing neurons to emphasizing the complex interplay between inflammatory response and autophagy in the brain vascular unit,covering various aspects such as the blood-brain barrier,astrocytes,microglia,and autophagy.This shift in research direction has provided us with a profound understanding of the mechanisms underlying cerebral infarction,offering strong support for innovative future treatment strategies.In this review,we delved into the importance of the interplay between inflammatory response and autophagy in the pathogenesis of cerebral infarction,emphasized the intricate interactions among these biological components,which might lay the groundwork for more effective managements and treatments of cerebral infarction.By comprehensively reviewing existing literatures,we proposed future research directions,aiming to provide more scientific and systematic guidance for the clinical management and treatment of cerebral infarction.

To understand the current quality status and rearing situation of Bombyx Batryticatus, the authors collected 102 batches of Bombyx Batryticatus from different main producing areas and five major Chinese medicine markets from 2016 to 2018, and measured the properties and quality of the silk gland, to clarify the quality status of Bombyx Batryticatus from different producing areas and markets. In addition, 35 batches of Bombyx Batryticatus from 2019 to 2022 were used to verify the silk gland after revision. Moreover, Beauveria Bassiana was inoculated in the silkworm of 4-5 instars, and standardized rearing was carried out until they die. The death rate and the quality of Bombyx Batryticatus were measured to determine the differences in Bombyx Batryticatus of different instars, and explore the rationality of the infection age of Bombyx Batryticatus in Chinese Pharmacopoeia(2020). The results revealed that in the 102 batches of Bombyx Batryticatus, the qualification rate of silk gland was low; the content of total ash far exceeded the standard; the content of beauvericin varied greatly. The qualification rate of the silk gland of the 35 batches of Bombyx Batryticatus was only 47.49%, which could be increased to 73.00% if the number of silk gland was 2 to 4. The death rate of Bombyx Batryticatus at different infection ages was quite different, with uneven quality. Generally, the yield of Bombyx Batryticatus inoculated on the first day of the fifth instar was high with good quality. Therefore, in combination with the quality and actual production of Bombyx Batryticatus, the following suggestions were proposed for revision of Bombyx Batryticatus in Chinese Pharmacopoeia(2025): The number of silk gland should be revised as 2-4 bright brown or bright black silk glands, after which, the quality of Bombyx Batryticatus could be guaranteed, and the "quality identification based on character" could also be reflected scientifically; the content determination index that the content of beauvericin shall not be less than 0.017% should be added to better control the quality of Bombyx Batryticatus; the infection age should be revised as the first day of the fifth instar to narrow the age span, which could better fit the actual production and ensure the quality of Bombyx Batryticatus.

OBJECTIVE: To investigate the spatial patterns of the prevalence, awareness, treatment, and control rates of dyslipidemia at the provincial level in China. METHODS: A national and provincial representative cross-sectional survey was conducted among 178,558 Chinese adults in 31 provinces in mainland China in 2018-2019, using a multi-stage, stratified, cluster-randomized sampling design. Subjects, as households, were selected, followed by a home visit to collect information. Both descriptive and linear regression procedures were applied in the analyses. RESULTS: The overall prevalence of dyslipidemia was 35.6%, and wide geographic variations of prevalence, treatment, and control rates of dyslipidemia were identified among 178,558 eligible participants with a mean age of 55.1 ± 13.8 years. The highest-lowest difference regarding the provincial level prevalence rates were 19.7% vs. 2.1% for high low-density lipoprotein cholesterol, 16.7% vs. 2.5% for high total cholesterol, 35.9% vs. 5.4% for high triglycerides, and 31.4% vs. 10.5% for low high-density lipoprotein cholesterol. The treatment rate of dyslipidemia was correlated with the socio-demographic index ( P < 0.001), urbanization rate ( P = 0.01), and affordable basic technologies and essential medicines ( P < 0.001). CONCLUSION Prevailing dyslipidemia among the Chinese population and its wide geographic variations in prevalence, treatment, and control suggest that China needs both integrated and localized public health strategies across provinces to improve lipid management.

With the aging of population intensifies and the level of population health have improved, thus much attention has been directed to how to delaying or preventing skin aging. Skin aging is associated with age, ultraviolet and lifestyle, mainly characterized as skin sagging, wrinkles, pigmentation, so it is urgent to seek traditional Chinese medicine and related cosmetics to solve the problem of skin aging. Traditional Chinese medicine has the functions of anti-oxidation, enhancing human immunity, promoting body metabolism and regulating endocrine, therefore, it has become a research focus in anti-skin aging. This article reviews the skin aging mechanism and the research advances of traditional Chinese medicine anti-skin aging, in order to provide a reference for future research and development of anti-aging traditional Chinese medicine.

Objective:To explore the difference of lymphocyte subsets in peripheral blood(PB)between aplastic anemia(AA)and hypoplastic myelodysplastic syndrome(hypo-MDS)patients,meanwhile to compare the clinical parameters obtained from PB and bone marrow(BM).Methods:The lymphocyte subsets in hypo-MDS(n=25)and AA(n=33)patients were investigated by flow cytometry.Meanwhile,the differences in PB cell counts,biochemical indicators,BM cell counts and abnormal chromosomes between the two groups were analyzed.Results:The percentage of CD8+T cells in A A group was significantly higher than that in hypo-MDS group(P=0.001),while the percentage of CD4+T cells and the CD4+/CD8+ratio in AA group were obviously lower than those in hypo-MDS group(P=0.015 and0.001,respectively).Furthermore,the proportion of CD4+andCD8+activated T(TA)cells,and memory Tregs in AA group was distinctly lower than those in hypo-MDS group(P=0.043,0.015 and 0.024,respectively).Nevertheless,the percentage of CD8+naive T(TN)cells in AA patients was remarkably higher(P=0.044).And hypo-MDS patients had declined lymphocyte counts(P=0.025),increased levels of total bilirubin(TBil),lactate dehydrogenase(LDH),vitamin B12 and proportion of BM blasts than AA patients(P=0.019,0.023,0.027 and 0.045,respectively).Conclusion:In this study it was confirmed that the percentages of CD4+and CD8+TA cells,memory Tregs and CD8+TN cells were significantly different between AA and hypo-MDS patients,which provide an essential basis for the identification of these two diseases.

OBJECTIVE Corona-virus disease 2019 (COVID-19) is an infectious disease caused by SARS-CoV-2 virus. The variant of corona-virus first identified in India, known as Delta, has become the dominant strain in China. Unfortunately, more conta-gious and unknown variants are coming, leading to a number of close contacts under quarantine. Chinese medicine (TCM) has been recommended to prevention and treatment due to the satisfactory therapeutic effects. However, the effect of TCM to decrease positive rate in close contacts remains unknown. METHODS We conducted an retrospective cohort study in Yangzhou, China to assess the effect of Chinese medicine on decreasing positive rate in close contacts under quarantine. The primary observation outcome was positive rate of Nucleic Acid Amplification Tests (NAATs). The secondary observation outcome was a composite of viral load of positive NAATs, severity levels of confirmed cases (asymptomatic, mild, moderate, or severe), daily body temperature, and levels of close contact (primary or secondary). RESULTS A total of 1286 subjects were collected, of which 1016 (79.00％) in TCM group and 270 (21.00％) in control group with 55 participants tested positive. The incidence of the primary outcome, positive rate of NAATs was significantly lower in the Chinese medicine group than in the control group, occurring in male and age≥60 years subjects. Multi-varia-ble logistic regression (excluding NO viral load) indicated that the risk of testing positive was reduced by 0.547 times in TCM groupcompared to control group. CT value of TCM group was higher than that of control group in all subjects and female subjects, and the re-sult showed statistically significant difference. CONCLUSIONS In our study involving close contacts under quarantine, Chinese medicine resulted in lower positive rate of NAATs and viral load than control.

Scutellariae Radix(Huangqin) is a well-known traditional Chinese medicine(TCM) used for the treatment of clearing heat in clinical application. It is bitter-cold by using directly, but the bitter-cold property can be relieved after wine-frying. The study of taste changes before and after wine-frying of Scutellariae Radix is of great significance in identifying Scutellariae Radix and wine-processed Scutellariae Radix and clarifying the traditional theory of wine-processing. In this experiment, 10 batches of Scutellariae Radix and wine-processed Scutellariae Radix were prepared. The contents of 5 flavonoids were determined by high performance liquid chromatography(HPLC), and principal component analysis(PCA) was performed with 5 flavonoids as variables. As a result, the contents were different in different batches of Scutellariae Radix, but Scutellariae Radix and wine-processed Scutellariae Radix could not be distinguished. Five sensory attributes(sour, salty, fresh, sweet, and bitter) were evaluated by artificial tasting, and the response values of 7 sensors(AHS, AHS, PKS, CTS, NMS, CPS, ANS, SCS) representing the taste of pieces were detected by electronic tongue. The correlation between sensory evaluation and response values of the electronic tongue were analyzed, and the results showed that the sensory evaluation of sour, salty, fresh, sweet, bitter and AHS, CTS, NMS, ANS, SCS sensors had different degrees of correlation, indicating that the electronic tongue technology can be used as an alternative to artificial taste and can serve as a means for quantifying the taste, and it can be used to evaluate the taste of TCM pieces. The taste method was used to analyze the response values of the electronic tongue, and the results showed that the bitterness of wine-processed Scutellariae Radix decreased and the salty taste increased. PCA was used to analyze taste changes before and after wine-processed Scutellariae Radix, and the results showed that taste differences between 2 pieces were divided into 2 categories. PCA loading scattering plots showed that response of saltiness and bitterness were the major factors to affect overall taste in Scutellariae Radix and wine-processed Scutellariae Radix. Based on electronic tongue response values, the Fisher discriminant model for Scutellariae Radix and wine-processed Scutellariae Radix was established, which showed that it could effectively discriminate them with a recognition rate of 100%. The experimental results showed that the electronic tongue combined with multivariate statistical analysis can be used to evaluate taste of TCM, at the same time, it could provide a fast and simple method for identifying different processed products.

Seminal duct obstruction may result in obstructive azoospermia (OA) and severe oligoasthenoteratozoospermia (OAT) (<0.5 million/mL) (Nordhoff et al., 2015). Cases of partial OA and OAT can be treated effectively by microsurgical anastomosis (Goldstein and Kim, 2013) to obtain successful surgical reversal. However, microsurgical vasovasostomy (VV) (Dickey et al., 2015) and vasoepididymostomy (VE) (Peng et al., 2017) are not suitable for patients with atypical OA and poor epididymis conditions or unpredictable obstruction of the distal vas deferens. For those patients, cross anastomosis may be applied instead of routine VE or VV. A single-center, retrospective, comparison study was conducted, which assessed the usefulness of the cross VV (CVV) in the scrotum for indication and efficacy. A total of 77 cases with OA or OAT were included, and 20 cases implemented cross anastomosis, including unilateral CVV (UCVV) in 4 cases, unilateral VE plus CVV (UVE+CVV) in 11 cases, and unilateral VV-based CVV (UVV+CVV) in 5 cases. The other 57 cases received no cross-matching anastomosis. The patency and natural pregnancy rates in one year were 75.0% and 50.0%, respectively, in the UCVV group; 54.5% and 27.3%, respectively, in the UVE+CVV group; and 60.0% and 40.0%, respectively, in the UVV+CVV group. The CVV in the scrotum in the selected patients with OA and severe OAT could yield good results. We regard the CVV in the scrotum as an efficacious operation with a lower risk of injury in cases of atypical OA.
