BACKGROUND:Prolyl hydroxylase domain 2(PHD2)inhibitors can regulate bone metabolism and relieve osteoporosis in ovariectomized rats.cpd17 is a small molecule oral PHD2 inhibitor newly developed by China Pharmaceutical University.It is effective in the treatment of renal anemia with few side effects,but its effect on bone formation and bone resorption is still unclear. OBJECTIVE:To investigate the effects of cpd17 on mouse osteogenic precursor cells. METHODS:Osteogenic precursor cells were treated with cpd17.Alkaline phosphatase activity and extracellular matrix mineralization were measured,and the expression levels of osteogenesis-and osteoclastogenesis-related markers,as well as PHD2 and hypoxia-inducible factor 1α,were detected.After inhibition of the hypoxia-inducible factor 1α pathway using LW6(a hypoxia-inducible factor 1α pathway inhibitor),alkaline phosphatase activity and extracellular matrix mineralization were detected again,as well as the expression levels of osteogenesis-and osteoclastogenesis-related markers,PHD2 and hypoxia-inducible factor 1α. RESULTS AND CONCLUSION:cpd17 significantly enhanced alkaline phosphatase activity and extracellular matrix mineralization,up-regulated the expression of osteogenesis-related markers,down-regulated the expression of osteoclastogenesis-related markers,up-regulated the expression of hypoxia-inducible factor 1α,down-regulate the expression of PHD2.However,cpd17's effects were significantly attenuated by LW6.To conclude,the PHD2 inhibitor cpd17 promotes osteogenic differentiation and inhibits osteoclastic differentiation through activation of the hypoxia-inducible factor 1α signaling pathway.

The European Society of Cardiology (ESC) released the "2024 ESC guidelines for the management of elevated blood pressure and hypertension" on August 30, 2024. This guideline updates the 2018 "Guidelines for the management of arterial hypertension." One notable update is the introduction of the concept of "elevated blood pressure" (120-139/70-89 mm Hg). Additionally, a new systolic blood pressure target range of 120-129 mm Hg has been proposed for most patients receiving antihypertensive treatment. The guideline also includes numerous additions or revisions in areas such as non-pharmacological interventions and device-based treatments for hypertension. This article interprets the guideline's recommendations on definition and classification of elevated blood pressure and hypertension, and cardiovascular disease risk assessment, diagnosing hypertension and investigating underlying causes, preventing and treating elevated blood pressure and hypertension. We provide a comparison interpretation with the 2018 "Guidelines for the management of arterial hypertension" and the "2017 ACC/AHA guideline on the prevention, detection, evaluation, and management of high blood pressure in adults."

Mycophenolic acid (MPA), the active moiety of both mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), serves as a primary immunosuppressant for maintaining solid organ transplants. Therapeutic drug monitoring (TDM) enhances treatment outcomes through tailored approaches. This study aimed to develop an evidence-based guideline for MPA TDM, facilitating its rational application in clinical settings. The guideline plan was drawn from the Institute of Medicine and World Health Organization (WHO) guidelines. Using the Delphi method, clinical questions and outcome indicators were generated. Systematic reviews, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence quality evaluations, expert opinions, and patient values guided evidence-based suggestions for the guideline. External reviews further refined the recommendations. The guideline for the TDM of MPA (IPGRP-2020CN099) consists of four sections and 16 recommendations encompassing target populations, monitoring strategies, dosage regimens, and influencing factors. High-risk populations, timing of TDM, area under the curve (AUC) versus trough concentration (C0), target concentration ranges, monitoring frequency, and analytical methods are addressed. Formulation-specific recommendations, initial dosage regimens, populations with unique considerations, pharmacokinetic-informed dosing, body weight factors, pharmacogenetics, and drug-drug interactions are covered. The evidence-based guideline offers a comprehensive recommendation for solid organ transplant recipients undergoing MPA therapy, promoting standardization of MPA TDM, and enhancing treatment efficacy and safety.

Objective:To investigate the effects of navigation bronchoscopy and artificial intelligence in the standardized training of residents on basic bronchoscopy skills, with the goal of enhancing their practical abilities.Methods:We selected 26 trainees (14 on standardized training of residents and 12 on standardized training of specialists) who participated in the basic navigational bronchoscopy skills and technique training (NBSTAT) at Ruijin Hospital, Shanghai Jiao Tong University School of Medicine from September 2023 to January 2024. The training was structured around a modular curriculum with navigation as the core design concept, consisting of five modules: lesion identification, precise localization, route planning, navigation operation, and real-time error correction. Theoretical teaching and skill practice were combined. The skill proficiency of the trainees was assessed using the Ruijin Hospital bronchoscopy simulation training system and the electromagnetic navigation bronchoscopy system. SPSS 26.0 was used to perform the t-test and Wilcoxon rank-sum test for comparisons. Results:After the training, the trainees as a whole showed significant improvements in practicing the skills, with the simulated operation time was reduced from (125.08±48.16) seconds to (77.69±24.75) seconds, the number of errors decreased from 1 to 0, the total score increased from (60.77±15.01) to (75.19±17.63), and the navigation operation time was reduced from 3 (3, 4) minutes to 2 (2, 3) minutes (all P<0.05). There were no significant differences in these assessment items between resident trainees and specialist trainees. The satisfaction rate of the trainees with the training reached 100.00%. Conclusions:The curriculum is effective in basic bronchoscopy skill training, remarkably enhancing the bronchoscopy skills of resident and specialist physicians, which is a useful approach for physicians to cope with the continuous development of diagnostic and therapeutic techniques for pulmonary diseases.

OBJECTIVE To investigate the protective effect and potential mechanism of cornuside on diabetic nephropathy (DN) model mice. METHODS Male KK-Ay mice were fed with high-fat and high-sugar diet for two weeks to reproduce the DN model. The successfully modeled mice were randomly grouped into model group, aminoguanidine group (positive control,100 mg/kg) and cornuside group (100 mg/kg), and male C57BL/6J mice were included as normal group, with 6 mice in each group. Administration groups were given relevant medicine intragastrically, and normal group and model group were given a constant volume of normal saline intragastrically, once a day, for 8 consecutive weeks. The levels of fasting blood glucose (FBG), 24 h urinary protein, serum interleukin-12 (IL-12), IL-10, blood urea nitrogen (BUN) and serum creatinine (Scr) were detected; the pathological injury, fibrotic change and glomerular microstructure of renal tissue were observed; the expressions of the receptor of advanced glycation end products (RAGE), collagen type Ⅳ (COL-Ⅳ) and inducible nitric oxide synthase (iNOS) in renal cortex were detected in each group. RESULTS Compared with normal group, the renal cortex of mice in model group showed obvious inflammatory cell infiltration and fibrotic changes; the mesangial hyperplasia of glomerulus was serious and the basement membrane had a large number of irregular dark dense deposits; the levels of FBG and 24 h urinary protein, the serum levels of IL- 12, BUN and Scr, and the expression levels of RAGE, COL-Ⅳ and iNOS in the renal cortex were significantly increased, while the serum level of IL-10 was significantly decreased (P<0.01). Compared with the model group, the renal pathological injuries, fibrotic changes and glomerular microstructure of mice in administration groups were improved significantly, and the above quantitative indexes were generally improved (P<0.05 or P<0.01). CONCLUSIONS Cornuside has a certain protective effect on DN model mice. It can inhibit the inflammatory response, reduce urinary protein excretion, and alleviate renal fibrosis, which may be related to the inhibition of the advanced glycation end products/RAGE signaling pathway.

OBJECTIVE To provide evidence for the safe clinical application of Trastuzumab for injection. METHODS Reports of adverse drug reaction (ADR) related to Trastuzumab for injection submitted in Beijing from June 2018 to May 2023 were collected. Statistical analyses were performed using SPSS 25.0 software. The gender and age of patients with ADRs, outcome, types of cancer, and the time of onset, severity, affected organs/systems of ADRs were included for analyses. The univariate Logistic regression analysis was conducted on patient fever and ADR prognosis. RESULTS A total of 195 patients with 318 instances of ADRs were included in the study. Women (87.69%) and patients aged 60-69 (33.85%) were more likely to experience ADRs. Breast cancer dominated (86.67%) in terms of cancer types; in terms of outcomes, most patients (67.69%) showed improvement, and some patients (27.69%) achieved full recovery. Overall, 68.72% of ADRs mainly occurred on the day of medication, and 95.38% of ADRs were of “moderate” severity. The most affected organs/systems were general diseases and various reactions at the administration site (40.57%), with chills (18.87%) and fever (18.24%) being the most common. Univariate Logistic regression analysis showed that fever mostly occurred within 1 day of medication (OR=5.63, 95%CI was 2.26-14.02, P< 0.001). The time of onset of ADR greater than 1 day was a risk factor for poor ADR prognosis (OR=20.08, 95%CI was 2.45- 164.43, P=0.005), mainly manifesting as bone marrow suppression and liver function abnormalities. Neutrophilia, cardiorespiratory arrest, and mixed liver damage were new ADRs not recorded in the drug’s instructions. CONCLUSION Women and patients aged ≥60 are high-risk groups for ADRs of Trastuzumab for injection. Chills and fever remain the most common ADRs of this drug, and these symptoms mostly occur within 1 day of medication, which have better prognoses. Close attention should be paid to the patient’s temperature changes on the day of drug infusion, with timely intervention. Regular monitoring of the patient’s hematological indicators is necessary to detect any bone marrow suppression and liver function abnormalities after medication.
