Diabetic kidney disease (DKD) with increasing global prevalence lacks effective therapeutic targets to halt or reverse its progression. Therapeutic targets supported by causal genetic evidence are more likely to succeed in randomized clinical trials. In this study, we integrated large-scale plasma proteomics, genetic-driven causal inference, and experimental validation to identify prioritized targets for DKD using the UK Biobank (UKB) and FinnGen cohorts. Among 2844 diabetic patients (528 with DKD), we identified 37 targets significantly associated with incident DKD, supported by both observational and causal evidence. Of these, 22% (8/37) of the potential targets are currently under investigation for DKD or other diseases. Our prospective study confirmed that higher levels of three prioritized targets-insulin-like growth factor binding protein 4 (IGFBP4), family with sequence similarity 3 member C (FAM3C), and prostaglandin D2 synthase (PTGDS)-were associated with a 4.35, 3.51, and 3.57-fold increased likelihood of developing DKD, respectively. In addition, population-level protein-altering variants (PAVs) analysis and in vitro experiments cross-validated FAM3C and IGFBP4 as potential new target candidates for DKD, through the classic NLR family pyrin domain containing 3 (NLRP3)-caspase-1-gasdermin D (GSDMD) apoptotic axis. Our results demonstrate that integrating omics data mining with causal inference may be a promising strategy for prioritizing therapeutic targets.

This study aims to establish a high-performance size-exclusion chromatography (HPSEC) method for determining the content of the classical swine fever virus (CSFV) E2 protein and screen the optimal stabilizer to enhance the stability of this protein. The optimal detection conditions were determined by optimizing the composition of the mobile phase, and characteristic chromatographic peaks were identified by SDS-PAGE and Western blotting. The specificity, repeatability, precision, linearity, limit of detection (LOD), and limit of quantitation (LOQ) of the method were assessed. The method established was used to determine the content of CSFV E2 protein antigen and vaccine. Differential scanning fluorimetry (DSF) was employed to screen the buffer system, pH, and salt ion concentrations, and sugar, amino acid, and alcohol stabilizers were further screened. The results showed that using a 200 mmol/L phosphate buffer provided the best column efficiency. An antigen-specific chromatographic peak appeared at the retention time of 18 min, which was identified as the CSFV E2 protein by SDS-PAGE and Western blotting. The method exhibited high specificity for detecting the CSFV E2 protein, with no absorbance peak observed in the blank control. The relative standard deviation (RSD) of the peak area for six repeated injections of the CSFV E2 protein was 0.74%, indicating good repeatability of the method. The RSD for repeated detection of two different concentrations of CSFV E2 protein samples by different operators at different time points was less than 2%, suggesting good intermediate precision of the method. The peak area of the CSFV E2 protein was linearly related to its concentration, with the regression equation showing R² of 1.000. The LOD and LOQ of the method were 14.88 μg/mL and 29.75 μg/mL, respectively. Application of the developed method in the detection of three batches of CSFV E2 protein antigen and three batches of vaccine demonstrated results consistent with those from the bicinchoninic acid (BCA) assay, which meant that the method could accurately determine the content of CSFV E2 protein antigen and vaccine. The DSF method identified 50 mmol/L Tris-HCl at pH 8.0 as the optimal buffer, and the addition of sugar and alcohol stabilizers further improved the stability of the CSFV E2 protein. The HPSEC method established in this study is simple, fast, and exhibits good accuracy and repeatability, enabling precise measurement of the CSFV E2 protein content. It is expected to play a crucial role in the quality control of the CSFV E2 vaccine. Furthermore, the strategy for improving the CSFV E2 protein stability, identified through DSF screening, has significant implications for enhancing the stability of the CSFV E2 vaccine.

OBJECTIVE Aimed at investigating whether reflux pharyngitis is an independent risk factor for the failure of type Ⅰ tympanoplasty for chronic otitis media.This is achieved by analyzing the relationship between the postoperative tympanic membrane healing in patients who underwent type Ⅰ tympanoplasty and pharyngolaryngeal reflux finding score(RFS).METHODS Patients who underwent type Ⅰ tympanoplasty in the Department of Otolaryngology Head and Neck Surgery,Nanshan People's Hospital,Shenzhen,China,from January 2023 to July 2024 were retrospectively included.All the patients received preoperative perfect nasal endoscopy,laryngoscopy,evaluation by the RFS questionnaire,preoperative otoscopy for tympanoplasty,pure tone hearing threshold,and temporal bone thin-layer CT examination.Postoperative otoscopic examination was performed to observe tympanic membrane healing and followed up for 3 months.The patients were divided into surgery success group and failure group based on the criterion of whether a complete tympanic membrane was formed by endoscopic examination within 3 months.The RFS scores of the two groups were statistically analyzed.RESULTS A total of 135 patients with an average age of 44.78 years(±12.22 years)took part in this study,with 60 males and 75 females included,and 68 left ears and 67 right ears involved.There were 120 patients in the surgery success group,and 15 patients in the failure group.Statistical analysis revealed that the RFS score of the patients in the tympanoplasty failure group was remarkably higher than that of the patients in the tympanoplasty success group.Moreover,there were significantly more cases with suspected reflux pharyngitis in the surgery failure group(P=0.007).Reflux-induced tympanic membrane lesion and reperforation mostly occurred in the central part of the tympanic membrane graft.CONCLUSION Reflux pharyngitis has been implicated with tympanoplasty failure,and thus may be a causative factor.Additionally,the RFS can be used to screen patients with chronic suppurative otitis media for suspected reflux pharyngitis.Findings from this work indicate that perioperative anti-reflux therapy,combined with dietary and lifestyle counselling for the patients who suffer from reflux pharyngitis and are about to undergo the tympanoplasty surgery may improve surgical success rate.

Objective To analyze the clinical characteristics and prognosis of patients with spon-taneous coronary artery dissection(SCAD).Methods A retrospective analysis was conducted in 40 patients with acute myocardial infarction(AMI).All patients were diagnosed with SCAD during hos-pitalization through coronary angiography(CAG)or intravascular ultrasound(IVUS).The clinical characteristics,CAG or IVUS findings,and treatment regimens of the patients were analyzed,and their prognosis was assessed through follow-up.Results Among 40 SCAD patients,there were 11 males and 29 females,with a mean age of(53.04±9.15)years.Twelve patients had identified causative factors,and seven patients presented with chest pain as the initial symptom.CAG or IVUS results showed that a total of 69 SCAD lesions were detected in 40 patients,with 15 patients having a single lesion.The primary treatment approach for the patients was medical therapy.The median fol-low-up duration was 34 months(ranging 2 to 48 months),during which 5 major adverse cardiovascu-lar and cerebrovascular events(MACCE)occurred.The patients were divided into MACCE group(5 patients)and non-MACCE group(35 patients)based on occurrence of MACCE.The mean age and the incidence of regional wall motion abnormalities on echocardiography were higher in the MACCE group than in the non-MACCE group(P＜0.05).Conclusion SCAD has distinct imaging features on CAG,and IVUS can confirm the diagnosis.Most patients are treated with medical therapy and have a generally favorable prognosis.However,patients with older age or regional wall motion abnormali-ties on echocardiography have poorer prognosis.
