Objective:
o develop an onset risk prediction nomogram for patients with homocysteine-type (H-type) hypertension (HTH) based on pulse diagram parameters to assist early clinical prediction and diagnosis of HTH.
Methods:
Patients diagnosed with essential hypertension and admitted to Shanghai Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Shanghai Hospital of Traditional Chinese Medicine, and Shanghai Hospital of Integrated Traditional Chinese and Western Medicine from July 6th 2020 to June 16th 2021, and from August 11th 2023 to January 22nd 2024, were enrolled in this retrospective research. The baselines and clinical biochemical indicators of patients were collected. The SMART-I TCM pulse instrument was applied to gather pulse diagram parameters. Multivariate logistic regression was adopted to analyze the risk factors for HTH. RStudio was employed to construct the nomogram model, receiver operating characteristic (ROC) curve, and calibration curve (bootstrap self-sampling 200 times), and clinical decision curve were drawn to evaluate the model’s discrimination and clinical effectiveness.
Results:
A total of 168 hospitalized patients with essential hypertension were selected and divided into non-HTH group (n = 29) and HTH group (n = 139). Compared with non-HTH group, HTH group had a lower body mass index (BMI), and higher proportions of male patients and drinkers (P < 0.05). The ventricular wall thickening (VWT) could not be determined. The proportions of left common carotid intima-media wall thickness (LCCIMWT) and serum creatinine (SCR) were higher in HTH group (P < 0.05). The pulse diagram parameter As was significantly higher, and H4/H1 and T1/T were lower in HTH group (P < 0.05). Gender, alcohol consumption, serum creatinine, and the pulse diagram parameter H4/H1 were identified as independent risk factors for HTH (P < 0.05). The nomogram’s area under the ROC curve (AUC) was 0.795 [95% confidence interval (CI): (0.706 6, 0.882 8)], with a specificity of 0.724 and sensitivity of 0.799. After 200 times repeated bootstrap self-samplings, the calibration curve showed that the simulated curve fits well with the actual curve (x2 =

OBJECTIVE To develop a population pharmacokinetic (PPK) model for mycophenolate mofetil active metabolite mycophenolic acid (MPA) in children with primary IgA nephropathy, explore the factors affecting the pharmacokinetic parameters of MPA, and provide a basis for clinical individualized therapy. METHODS Retrospective collection was conducted on 636 concentrations and clinical data from 47 pediatric patients with primary IgA nephropathy. PPK analysis was carried out by using the nonlinear mixed-effects model; the covariates were tested with a stepwise method. Goodness-of-fit plots, Bootstrap and visual predictive check were employed to evaluate the final model. RESULTS The pharmacokinetics of MPA in children with IgA nephropathy in vivo conformed to the first-order absorption and elimination two-compartment model (objective function value of 3 276.31). Covariate analysis suggested that body weight and albumin (ALB) levels were significant influencing factors on apparent clearance rate and apparent distribution volume. The typical values of PPK parameters of MPA in the final model were as follows: the central room had a distributed volume of 5.79 L, the clearance rate was 4.06 L/h, the volume of peripheral ventricular distribution was 430.93 L, the clearance rate between compartments was 15.40 L/h, the oral absorption rate constant was 1.29 h-1. After verification, most of the predicted corrected observed concentration points were within the 90% confidence interval of the predicted corrected simulated concentration, indicating that the MPA final model had good predictive performance. CONCLUSIONS The PPK model of MPA in children with primary IgA nephropathy is established in this study, identifying body weight and ALB levels are significant factors affecting MPA metabolism.

OBJECTIVE To explore the potential mechanism of the effect of Xuebijing injection (XBJ) on neurological function and survival of rats after cardiac arrest (CA)/cardiopulmonary resuscitation (CPR) based on the S-nitrosoglutathione reductase (GSNOR)/S-nitrosoglutathione (GSNO) pathway. METHODS The CA/CPR rat model was established by ventricular fibrillation. Using a sham operation group as control, high-throughput sequencing was employed to analyze and mine the differentially expressed genes (DEGs). Enzyme-linked immunosorbent assay was used to determine the contents of GSNOR and GSNO in the hippocampus; the active components of XBJ were screened and subjected to molecular docking analysis with GSNOR. The rats successfully modeled using the same method were divided into model group (n=30), inhibitor (GSNOR inhibitor) group (n=30), XBJ group (n=30) and XBJ+inhibitor group (n=30), and a sham operation group (n=30) was set up. Neurological function was evaluated and survival status was recorded at 3 hours, 24 hours and 3 days after the first 89) drug intervention. The contents of GSNOR and GSNO in the hippocampus of rats were determined in each group at the 0191) above time points, and the relationship of the contents of GSNOR and GSNO with modified neurologic severity scale (mNSS) score was analyzed. RESULTS GSNOR coding gene was differentially expressed between the model group and the sham operation group. Compared with the sham operation group, GSNOR content increased significantly in the hippocampus of rats in model group, while GSNO content decreased significantly (P<0.05). The active components of XBJ, such as 4- methylenemiltirone and salviolone, could be bound to GSNOR protein, with the binding energy lower than -6 kcal/mol, mainly connected by hydrogen bonds. Animal experiments revealed that mNSS score and GSNOR levels in the hippocampus of rats in the model group were significantly higher than those in the sham operation group (P<0.05), while GSNO levels and survival rate were significantly lower than those in the sham operation group (P<0.05). The above indexes of rats were improved significantly in administration groups, the mNSS score in the XBJ group was significantly lower than that in the inhibitor group, the content changes of GSNOR and GSNO in the inhibitor group were more obvious than those in the XBJ group, and the various indicators in the XBJ+inhibitor group were significantly better than the XBJ group and the inhibitor group (P<0.05). GSNOR content was positively correlated with the mNSS score, and GSNO content was negatively correlated with the mNSS score (P<0.05). CONCLUSIONS XBJ can improve the neurological function of rats and enhance their survival rates after CA/CPR, the mechanism of which may be associated with the down-regulation of GSNOR and the up-regulation of GSNO.

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.
