Immunoglobulin A nephropathy （IgAN） is the primary glomerulonephritis with the highest incidence rate in the world. It is also the main cause of end-stage renal disease （ESRD） in China， which has brought heavy economic burden to the society and patient families. Traditional Chinese medicine （TCM） has certain advantages in treating IgAN. In TCM， IgAN is classified into consumptive disease， hematuria， and edema categories， with the location in the kidney and involving the lung， liver， and spleen. Professor Ren Jixue， a master of TCM， believes that kidney deficiency and spleen deficiency are the root causes of IgAN， and the throat is the source of the disease. He proposed the theory of throat-kidney correlation and used the method of tonifying kidney and invigorating spleen as well as detoxifying and relieving sore-throat to treat IgAN， achieving significant therapeutic effects. Studies have shown that IgAN is closely related to mucosal immune defense. IgAN patients often experience recurrent and gradually worsening symptoms due to mucosal infections， and polymeric Ig receptor （PIgR） is an important component of mucosal defense function. The lack of PIgR leads to the accumulation of IgA molecules in the mucosal lamina propria， and the molecules enter the bloodstream in large quantities and ultimately deposit in the kidneys， causing kidney damage. Complement regulatory protein complement receptor type 1 （CR1） exists on red blood cells and glomeruli and has the function of inhibiting the activation and differentiation of B cells， clearing immune complexes， and inhibiting excessive activation of the complement system. Therefore， regulating the immune defense function through the mucosal-renal axis mediated by PIgR-CR1 will be an important target for preventing and treating IgAN. Based on the theory of throat-kidney correlation， this article explores the effects and molecular mechanisms of tonifying kidney and invigorating spleen as well as detoxifying and relieving sore-throat in preventing and treating IgAN by regulating the mucosal-kidney axis mediated by PIgR-CR1. It provides effective theoretical support and a scientific basis for TCM prevention and treatment of IgAN based on the theory of throat-kidney correlation.

ObjectiveTo explore the current status and issues regarding the application of ancient books in clinical practice guidelines and expert consensus of traditional Chinese medicine （TCM） published in China， and to provide methodological recommendations for the incorporation of ancient books in the development of TCM guidelines. MethodsWe searched China National Knowledge Infrastructure （CNKI）， WanFang Data， VIP， SinoMed， PubMed， Embase， as well as six industry websites including China Association of Chinese Medicine， National Group Standards Information Platform， and Chinese Association of the Integration of Traditional and Western Medicine，etc. TCM clinical practice guidelines or expert consensus issued during January 1st， 2017， to November 26th， 2022 were searched. Clinical practice guidelines or expert consensus that explicitly referred to ancient books were included， and the content regarding the searching for ancient books， sources of access to ancient books， methods of evaluating the level of evidence， methods of evaluating the level of recommendation， and methods of evaluating the evidence for the ancient books were analysed. ResultsA total of 1,215 TCM clinical practice guidelines or expert consensus were retrieved， with 442 articles explicitly mentioning the application of ancient books， including 300 （67.87%） clinical practice guidelines and 142 （32.13%） expert consensus. Sixty of the 442 publications explicitly reported that ancient books searching had been conducted （13.57%）； among these 60 publications 27 （45.00%） explicitly reported ancient books searching strategies， and the most frequent method was manual searching with a total of 24 articles （40.00%）. The most popular search source was Chinese Medical Dictionary， a TCM classics database， with a total of 18 articles. 197 articles （44.57%） explicitly reported the evaluation criteria for the level of evidence， of which 141 articles （71.57%） involved the evaluation criteria for the ancient books； 413 articles （93.44%） mentioned ancient books in the recommendations， and only the source of formula name was mentioned in 409 （99.03%） of the publications. ConclusionThe current application of ancient books in TCM clinical practice guidelines and expert consensus is limited， with issues of non-standard searching and evaluation methods. Standar-dization and uniformity are needed in evidence grading and recommendation standards. Future research should clarify the scope and methods of applying ancient book， emphasize their integration with modern research evidence， and enhance their value and quality in the development of TCM clinical practice guidelines.

Background::While type 2 diabetes mellitus (T2DM) is considered a putative causal risk factor for coronary artery disease (CAD), the intrinsic link underlying T2DM and CAD is not fully understood. We aimed to highlight the importance of integrated care targeting both diseases by investigating the phenotypic and genetic relationships between T2DM and CAD.Methods::We evaluated phenotypic associations using data from the United Kingdom Biobank ( N = 472,050). We investigated genetic relationships by leveraging genomic data conducted in European ancestry for T2DM, with and without adjustment for body mass index (BMI) (T2DM: Ncase/ Ncontrol = 74,124/824,006; T2DM adjusted for BMI [T2DM adjBMI]: Ncase/ Ncontrol = 50,409/523,897) and for CAD ( Ncase/ Ncontrol = 181,522/984,168). We performed additional analyses using genomic data conducted in multiancestry individuals for T2DM ( Ncase/ Ncontrol = 180,834/1,159,055). Results::Observational analysis suggested a bidirectional relationship between T2DM and CAD (T2DM→CAD: hazard ratio [HR] = 2.12, 95% confidence interval [CI]: 2.01–2.24; CAD→T2DM: HR = 1.72, 95% CI: 1.63–1.81). A positive overall genetic correlation between T2DM and CAD was observed ( rg = 0.39, P = 1.43 × 10 -75), which was largely independent of BMI (T2DM adjBMI–CAD: rg = 0.31, P = 1.20 × 10 –36). This was corroborated by six local signals, among which 9p21.3 showed the strongest genetic correlation. Cross-trait meta-analysis replicated 101 previously reported loci and discovered six novel pleiotropic loci. Mendelian randomization analysis supported a bidirectional causal relationship (T2DM→CAD: odds ratio [OR] = 1.13, 95% CI: 1.11-1.16; CAD→T2DM: OR = 1.12, 95% CI: 1.07-1.18), which was confirmed in multiancestry individuals (T2DM→CAD: OR = 1.13, 95% CI: 1.10-1.16; CAD→T2DM: OR = 1.08, 95% CI: 1.04-1.13). This bidirectional relationship was significantly mediated by systolic blood pressure and intake of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, with mediation proportions of 54.1% (95% CI: 24.9-83.4%) and 90.4% (95% CI: 29.3-151.5%), respectively. Conclusion::Our observational and genetic analyses demonstrated an intrinsic bidirectional relationship between T2DM and CAD and clarified the biological mechanisms underlying this relationship.

Objective To investigate the correlation between the total CSVD burden and fundus vasculopathy,and evaluate significance of fundus vasculopathy for cognitive impairment in CSVD patients.Methods A total of 290 inpatients who taking physical examination in our department from May 2021 to August 2022 were consecutively recruited,and according to their score of CSVD,they were divided into group 0(129 cases),group 1(51 case),group 2(42 cases),group 3(44 cases),and group 4(24 cases).All the subjects underwent brain magnetic resonance imaging,fundus fluorescein angiography,and cognitive function assessment.The total CSVD burden and fundus vasculopathy were evaluated.The general clinical data,results of laboratory tests,fundus vascularization,and cognitive function were compared among the groups with different CSVD burden scores.Spearman correlation analysis and linear correlation analysis were used to explore the correlation between total CSVD burden score and fundus vascular disease.Results Significant differences were observed in terms of age,years of education,cerebral infarction/TIA,total cho-lesterol,LDL-C,creatinine,MoC A and MMSE scores,positive results of connectivity test,digit-symbol conversion test,Stroop colour-word interference test and verbal fluency test,values of CRAE,CRVE,AVR,Scheie grade,DWMH and PVWMH,enlarged perivascular space in the basal ganglia(BG-EPVS),lacunar infarct and cerebral microbleeds(CMB)in different CSVD total bur-den groups(P＜0.05,P＜0.01).Spearman correlation analysis showed that total CSVD burden was negatively correlated with CRAE and AVR(r=-0.655,P=0.000;r=-0.679,P=0.000),and positively with CRVE and Scheie grade(r=0.560,P=0.000;r=0.685,P=0.000).Multivari-ate linear analysis showed that the total CSVD burden after adjusting for relevant risk factors was significantly correlated with CRAE,CRVE,AVR and Scheie grades(P＜0.01).Conclusion Fun-dus vasculopathy is strongly associated with increased total CSVD burden,and it can be regarded as a valid predictor of CSVD-related cognitive impairment.

With the development of modern sequencing techniques and bioinformatics, genomes that were once thought to be noncoding have been found to encode abundant functional micropeptides (miPs), a kind of small polypeptides. Although miPs are difficult to analyze and identify, a number of studies have begun to focus on them. More and more miPs have been revealed as essential for energy metabolism homeostasis, immune regulation, and tumor growth and development. Many reports have shown that miPs are especially essential for regulating glucose and lipid metabolism and regulating mitochondrial function. MiPs are also involved in the progression of related diseases. This paper reviews the sources and identification of miPs, as well as the functional significance of miPs for metabolism-related diseases, with the aim of revealing their potential clinical applications.

Objective To quickly observe the tonic effects of Cervi Colla on enriching blood,strengthening bones and anti-aging in zebrafish model.Methods Glyphosate(Gly)was used to construct the erythrocyte injury model in adult zebrafish,and methotrexate(MTX)was used to construct the hematopoietic function injury model of juvenile zebrafish.Prednisolone(Pred)was used to establish the inhibition model of bone formation in zebrafish larvae.The ocular cell apoptosis model of zebrafish larvae was established by dibutyl phthalate(DBP).Results Cervi Colla could improve the Gly-induced abnormal erythrocyte nucleus in adult zebrafish and promote the expression of hematopoietic factors SCL and GATA1.Cervi Colla improved Pred-induced inhibition of bone formation in juvenile zebrafish,and promoted the expression of osteoblast-related gene ALP and Runx2a.The number of ocular cell apoptosis induced by DBP was decreased,and the expression of anti-apoptotic factor Bcl-2 was promoted.Conclusion Cervi Colla has significant effects on protecting erythrocyte,protecting hematopoiesis,protecting bone formation and anti-apoptosis.These effects may be related to replenish blood,anti-osteoporosis,and anti-aging.This study provides a scientific basis for the clinical application of Cervi Colla,and lays a foundation for further development and application.

Objective: Taxifolin is a natural flavonoid compound that can be isolated from onions, grapes, oranges and grapefruit. It also acts as a medicine food homology with extraordinary antioxidant and anti-inflammatory activity. This study aims to explain the protective effects and potential mechanisms of taxifolin against inflammatory reaction. Methods: Levels of interleukin (IL)-6, IL-1β and intracellular reactive oxygen species (ROS) were assessed in different time after the treatment of taxifolin in RAW264.7 cells induced by lipopolysaccharide (LPS). Subsequently, the mRNA and protein levels of inducible nitric oxide synthase (iNOS), vascular endothelial growth factor (VEGF), cyclooxygenase (COX)-2, tumor necrosis factor (TNF)-α and the phosphorylation expression levels of the MAPK signal pathway were also evaluated. A silico analysis was used to explain the binding situation for the investigation of taxifolin and MAPK signal pathway. And then MAPK inhibitors were used to reveal the expression level of iNOS, VEGF, COX-2 and TNF-α in RAW264.7 cells. Results: It was demonstrated that cell inflammatory damage induced by LPS was significantly alleviated after the treatment of taxifolin. Then, the mRNA and protein levels of iNOS, VEGF, COX-2 and TNF-α were reduced and the phosphorylation expression levels of the MAPK signal pathway were down-regulated remarkably as well. In silico analysis, taxifolin could form a relatively stable combination with MAPK signal pathway. MAPK inhibitors showed increasing or decreasing effect in the mRNA levels of iNOS, VEGF, COX-2 and TNF-α, which suggesting that taxifolin down-regulated iNOS, VEGF, COX-2 and TNF-α expressions were not entirely through the MAPK pathway. Conclusion: This finding demonstrated that taxifolin improved the inflammatory responses that partly involved in the phosphorylation expression level of MAPK signal pathway in RAW264.7 cells exposed to acute stress.

Objective:To investigate the prevention and treatment status of venous thromboembolism (VTE) of pregnant women in general hospitals and specialized hospitals in China.Methods:This study was a cross-sectional survey about VTE prevention and treatment in 112 hospitals across China from January 1st to December 31st, 2019, including general information, resource accessibility, hospital system and strategy. According to the characteristics, the hospitals were divided into general hospital group (70 hospitals) and specialized hospital group (42 hospitals). The basic information, VTE diagnosis and treatment resources, prevention systems and the preference of the VTE risk assessment form of the two groups were compared. Logistic regression was used to analyze the proportion of VTE incidence and related factors in the two groups of hospitals.Results:(1) The median annual delivery volume of the general hospital group was significantly lower than that of the specialized hospital group (3 428 vs 9 969 cases, P<0.01), the diagnostic accessibility of CT pulmonary angiography (CTPA) was significantly higher than that of the specialized hospital [92.9% (65/70) vs 59.5% (25/42), P<0.01], and the proportion of obstetric VTE risk assessment was significantly higher than that of the specialized hospital group [85.7% (60/70) vs 66.7% (28/42), P=0.017]. (2) Among the 88 hospitals using the VTE risk assessment sheet, the utilization rate of the evaluation sheet recommended by the obstetric VTE guideline in specialized hospitals (78.6%, 22/28) was higher than that of general hospitals (48.3%, 29/60), and the difference was statistically significant ( P=0.007). (3) The proportion of VTE incidence in general hospital group was 0.126% (360/286 517), and the proportion of VTE incidence in specialized hospital group was 0.032% (154/484 111). Logistic regression analysis showed that the OR value of the specialized hospital group was 0.253 (95% CI: 0.209-0.305) and the difference was statistically significant ( P<0.01) compared with the general hospital group. After adjusting the hospital level, B-ultrasonography and CTPA accessibility, whether to establish a risk assessment and obstetric VTE system, the proportion of VTE incidence in specialized hospitals was still lower than that in general hospitals ( OR=0.307, 95% CI: 0.251-0.376, P<0.01). Conclusions:General hospitals have higher access to resources for diagnosing VTE than specialized hospitals, and the VTE evaluation system is better implemented. The utilization rate of the obstetric VTE guidelines in specialized hospitals is higher than that of general hospitals.
