Objective: To understand the prevalence of elevated blood pressure and its association with dietary patterns in children and adolescents in China, providing evidence for developing dietary intervention of hypertension in children and adolescents. Methods: Data were derived from the China Children s Nutrition and Health System Survey and Application Project(2019-2021). A stratified cluster random sampling method was used to include 7 933 participants from 28 survey sites in seven major regions of Northeast, North, Northwest, East, Central, South and Southwest China. Multivariate Logistic regression models were used to analyze associations between demographic characteristics, nutritional status and elevated blood pressure. Exploratory factor analysis identified dietary patterns, which were divided into three quartile groups (T3, T2, T1) based on factor scores (compliance for dietary pattern) from high to low, and multivariate Logistic regression model assessed the correlation between elevated blood pressure and dietary patterns. Results: The prevalence of elevated blood pressure was 15.4% among Chinese children aged 7-17 years. Significant differences were observed across nutritional status (reference: underweight; normal weight: OR =1.57; overweight: OR = 2.61 ; obesity: OR =3.85), urban/rural residence (reference: rural; urban: OR =0.86), and paternal education (reference: junior high school and below; bachelor degree or above: OR =0.68) ( P <0.05). The detection rates of high blood pressure in T3 group children and adolescents with four dietary patterns (staple food, animal based food, snacks, vegetables and fruits) were 15.7%, 14.6%, 16.8%, and 15.8%, respectively. After adjusting for residence, paternal education, and nutritional status, the "snack dietary pattern" (mainly candy, sugar sweetened beverages, and processed snacks) showed positive associations with elevated blood pressure in T2 ( OR =1.21) and T3 ( OR =1.19) tertiles ( P <0.05). Conclusions The snack dietary pattern is a related factor for elevated blood pressure in children and adolescents. Restricting unhealthy snack intake may promote cardiovascular health.

Folic acid is a fully oxidized synthetic folate with high bioavailability and stability which has been extensively prescribed to prevent congenital disabilities. Here we revealed the immunosuppressive effect of folic acid by targeting splenic marginal zone B (MZB) cells. Folic acid demonstrates avid binding with the Fc domain of immunoglobulin M (IgM), targeting IgM positive MZB cells in vivo to destabilize IgM-B cell receptor (BCR) complex and block immune responses. The induced anergy of MZB cells by folic acid provides an immunological escaping window for antigens. Covalent conjugation of folic acid with therapeutic proteins and antibodies induces immunological evasion to mitigate the production of anti-drug antibodies, which is a major obstacle to the long-term treatment of biologics by reducing curative effects and/or causing adverse reactions. Folic acid acts as a safe and effective immunosuppressant via IgM-mediated MZB cells targeting to boost the clinical outcomes of biologics by inhibiting the production of anti-drug antibodies, and also holds the potential to treat other indications that adverse immune responses need to be transiently shut off.

OBJECTIVE To investigate the improvement effects of Runchang granules on the constipation in mice and its potential mechanism. METHODS The mice were randomly divided into normal control group， model group， Runchang granules low-dose and high-dose groups （5， 10 g/kg）， mosapride group （0.003 g/kg， positive control）， with 6 mice in each group. The latter 4 groups were given loperamide intragastrically （0.004 g/kg）， twice a day， for 3 consecutive days. Normal control group and model group were given purified water intragastrically， and administration groups were given relevant medicine intragastrically for 7 consecutive days. After the last medication， fecal moisture content and intestinal motility of mice were determined， while the structures of colon and ileum， and the secretion of colonic mucus were observed. Protein expressions of tyrosine kinase receptor （c-kit）， mucin 2 （MUC2） and stem cell factor （SCF） were determined in colon； meanwhile， the mRNA expression levels of inflammatory factors [tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， IL-1β， inducible nitric oxide synthase （iNOS）] as well as factors related to promoting intestinal motility [neuronal nitric oxide synthase （nNOS）， smooth muscle myosin light chain kinase （smMLCK）， 5-hydroxytryptamine 4 receptor （5-HT4R）， MUC2， SCF， c-kit] were determined. RESULTS Compared with model group， the fecal water content， intestinal propulsion rate， protein expression of c-kit in colon， relative expressions of MUC2 and SCF protein， and mRNA expressions of factors related to promoting intestinal motility （except for nNOS and SCF in Runchang granules low-dose group） were all increased significantly in Runchang granules low-dose and high-dose groups， and mosapride group （P＜0.05 or P＜0.01）. mRNA expression levels of inflammatory factors were decreased significantly（P＜0.05 or P＜0.01）. Both colon and ileum injuries improved， and the secretion of colon mucus was increased significantly in Runchang granules high-dose group （P＜0.01）. CONCLUSIONS Runchang granules have laxative effect and can improve constipation in mice， and its mechanism may be related to the promotion of the secretion of colon mucus and MUC2 expression， and the activation of SCF/c-kit signaling pathway.

BACKGROUND:There is no consensus on the optimal bone tunnel position in the lateral clavicle,which guides coracoclavicular ligament reconstruction.Postoperative complications such as enlargement of the lateral clavicle bone tunnel,bone osteolysis,clavicle fracture,and failure of internal fixation are likely to occur.Bone mass density plays an important role in the strength and stability of endophytic fixation.Regional differences in the bone mass density of the distal clavicle should not be overlooked in the repair and reconstruction of acromioclavicular dislocation.Currently,there are no quantitative clinical studies in humans regarding the bone mass density of the distal clavicle. OBJECTIVE:To measure the magnitude of bone mass density in different regions of the distal clavicle by quantitative CT to provide a reference for surgeons to repair and reconstruct the coracoclavicular ligament. METHODS:101 patients undergoing quantitative CT checking in Fuyang People's Hospital Affiliated to Anhui Medical University from October to December 2022 were enrolled,from which 1 616 samples of subdivisional bone mass density of the distal clavicle were measured.For each of the quantitative CT samples,firstly,the distal clavicle was divided medially to laterally into the following four regions:conical nodal region(region A),inter-nodal region(region B),oblique crest region(region C)and distal clavicular region(region D).Secondly,each region was divided into the first half and the second half to determine eight subdivisions,then setting semiautomatic region of interest(ROI)in each subdivision:(ROI A1,A2,B1,B2,C1,C2,D1,and D2).Thirdly,each quantitative CT scan was transferred to the quantitative CT pro analysis workstation,and cancellous bone mass density was measured in the distal clavicle ROI.Finally,the clavicular cortex was avoided when measuring. RESULTS AND CONCLUSION:(1)There was no statistically significant difference in bone mineral density on the different sides of the shoulder(P＞0.05).(2)The analysis of bone mineral density in eight sub-areas of the distal clavicle A1,A2,B1,B2,C1,C2,D1,and D2 showed statistically significant differences(P＜0.05).It could be considered that there were differences in bone mineral density in different areas of the distal clavicle.After pairwise comparison,there was no statistically significant difference in bone mineral density between A1 and A2,D1 and D2,A2 and B1(P＞0.05),and there was a statistically significant difference in bone mineral density between the other sub-areas(P＜0.05).(3)The bone mineral density in the region A2 of the anatomical insertion of the conical ligament was significantly higher than that in the inter-nodular area(region B)(P＜0.05).The bone mineral density in the region A1 was higher than that in the region A2,but the difference was not statistically significant(P＞0.05).The bone mineral density in the region C1 of the anatomical insertion of the trapezium ligament was higher than that in regions C2,D1 and D2,and the bone mineral density in the inter-nodular area(region B)was significantly higher than that in regions C and D(P＜0.05).(4)These results have suggested that there are differences in bone mass density in different regions of the distal clavicle;regional differences in bone mass density in the distal clavicle during repair and reconstruction of acromioclavicular dislocation cannot be ignored.Consideration should be given not only to biomechanical factors but also to the placement of implants or bone tunnels in regions of higher bone mass density,which could improve the strength and stability of implant fixation and reduce the risk of complications such as bone tunnel enlargement,osteolysis,fracture and implant failure.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objective To observe the value of 5.0T MRI in measuring the volumes of hippocampal formation(HF)subfields in healthy adults.Methods Cranial high-resolution TIWI were prospectively obtained in 23 healthy adult volunteers using 5.0T and 3.0T MR scanners,respectively.HF was divided into 38 subfields,and then the volume of each subfield was measured using FreeSurfer software.The volumes of HF subfield based on 5.0T and 3.0T MR T1WI were compared,and the correlations of the outcomes were analyzed.Results Significant differences of the volumes of bilateral hippocampal tails,left parasubiculum,left molecular layer of hippocampal head,left granular cell-molecular layer-dentate gyrus head,right granular cell-molecular layer-dentate gyrus body,left cornu Ammonis(CA)1 head,left CA3 head,left CA4 head,right fimbria of hippocampus and left hippocampus amygdala transition area were found between 5.0T and 3.0T T1WI(all P＜0.05).The volumes of HF subfields measured based on 5.0T and 3.0T T1WI were moderately to highly positively correlated(all r＞0.5,all P＜0.01).Conclusion 5.0T MRI could be used to measure the volume of HF subfield in adults.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To evaluate the potential causal relationship between inflammatory factors and PCa using the two-sample Mendelian randomization(MR)method.Methods:We selected summary statistics of genome-wide association studies(GWAS)(n=14 824)on 91 inflammatory factors,with PCa as the outcome in the latest 9th edition of FinnGen database for MR analysis.We evaluated the causal relationship between inflammatory factors and PCa using the odds ratio(OR)and 95%confidence interval(CI)of such regression models as inverse variance weighting(IVW),MR-Egger regression,simple mode(SM),weighted mode(WM)and weighted median estimator(WME),with IVW as the main statistical method for this study.We further verified the results of MR by Bayesian analysis,and evaluated the heterogeneity of genetic instrumental variables,pleiotropic effects and sensitivity of single nu-cleotide polymorphisms(SNP)as instrumental variables to the exposure-outcome relationship by Cochran's Q test,MR-Egger intercept test and leave-one-out cross validation.Results:IVW showed that among the 91 inflammatory factors,interleukin-22 receptor A1(IL-22RA1)and sulfotransferase 1A1(ST1A1)were correlated positively with the risk of PCa;IL-22RA1:IVW(OR[95%CI]:1.12[1.00-1.25],P=0.04);ST1A1:IVW(OR[95%CI]:1.08(1.00-1.16),P=0.03),while Chemokine ligand 11(CXCL11)and interleukin 17 A(IL-17 A)negatively with the risk of PCa;CXCL11:IVW(OR[95%CI]:0.88[0.81-0.95],P=0.00);IL-17A:IVW(OR[95%CI]:0.91[0.84-0.98],P=0.02).No potential horizontal pleiotropy was detected by MR-Egger intercept analysis(P>0.05,IL-22RA1=0.885,ST1A1=0.949,CXCL11=0.391,IL-17A=0.884),nor biased SNPs in the MR pleiotropy residual sum and outlier(MR-PRESSO)test(P>0.05,IL-22RA1=0.479,ST1A1=0.629,CXCL11=0.326,IL-17A=0.444),or heterogeneity P>0.05,IL-22RA1=0.543,ST1A1=0.677,CXCL11=0.336,IL-17A=0.494).Leave-one-out sensitivity analysis indicated no significant impact of individual SNP sites on the overall causal rela-tionship prediction,suggesting the reliable results of analysis.Conclusion:Among the 91 inflammatory factors,IL-22RA1 and ST1A1 have a positive causal relationship,while CXCL11 and IL-17A have a negative causal relationship with PCa.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.
