Objective To evaluate the sensitivity,repeatability,anti-degradation ability,in vivo temporal stability,and tissue specificity of the DNA methylation sequencing panel constructed in our previous study for height inference,so as to provide a reference for forensic application.Methods Sensitivity:different initial template quantities(50 ng,40 ng,30 ng,20 ng)were set for sequencing.Repeatability:DNA from the same sample was sequenced three times.Anti-degradation ability:whole blood was used to make blood stains,and DNA was extracted and sequenced at 0,3,6 and 9 months,respectively.In vivo temporal stability:the blood was collected at 0,3,6,and 9 months for sequencing.Tissue specificities:published data and findings were used to analyze the tissue specificities of CpGs in the panel.Results The sensitivity test showed that the initial template quantities of 20 ng detected all the CpG sites and still obtained accurate prediction results.The results of the three repeated predictions of the same sample are stable,and the differences are mainly due to the randomness of the DNN model,indicating good detection repeatability.A complete methylation profile was obtained for the blood stains left at room temperature for 9 months,and the predicted results showed a small range of fluctuations.The three samples were predicted to fluctuate within a range of 1.5 cm or less over nine months.Tissue-specific analyses showed a high correlation between blood and saliva,but can not apply to other tissues.Conclusion The DNA methylation detection system we developed in our previous study has good sensitivity,repeatability,anti degradation ability,in vivo time stability,as well as strong tissue specificity,making it suitable for height inference of blood samples.This supports the feasibility of using targeted DNA methylation analysis on whole blood samples to infer height in the field of forensic science.

BACKGROUND:Polyamines play a crucial role in tissue calcification.Spermidine/spermine N1-acetyltransferase 1(SAT1),as a key rate-limiting enzyme regulating intracellular polyamine metabolism,has been associated with various pathological processes.However,its role in vascular calcification remains unclear.OBJECTIVE:To investigate the role of SAT1 in rat vascular smooth muscle cell calcification.METHODS:(1)Bioinformatics analysis:Differential expression of SAT1 in human carotid atherosclerotic plaques and their surrounding healthy carotid artery tissues were using GEO datasets.PanglaoDB database was used to analyze SAT1 expression abundance and localization across different cell types through single-cell sequencing.(2)Rat vascular smooth muscle cells were divided into three groups:a control group cultured in DMEM medium,a calcification group induced by DMEM medium containing 10 mmol/L β-glycerophosphate sodium and 3 mmol/L calcium chloride,and the 50,100 μmol/L diacetylaminotriazamidine groups treated with the SAT1 inhibitor,diacetylaminotriazamidine,in addition to the calcification medium.After 7-10 days of culture,alizarin red S staining was performed,and cellular calcium content and alkaline phosphatase activity were assessed.Western blot was used to detect the protein expression of Runt-related transcription factor 2,bone morphogenetic protein 2,alpha-smooth muscle actin,and SAT1.Immunofluorescence staining was conducted to examine the expression of Runt-related transcription factor 2 and SAT1.RESULTS AND CONCLUSION:(1)Bioinformatics analysis revealed significantly upregulated expression of SAT1 and Runt-related transcription factor 2(P<0.05)in carotid atherosclerotic plaques compared with healthy carotid tissues(P<0.05).Single-cell sequencing database analysis confirmed SAT1 expression in vascular smooth muscle cells.(2)Compared with the control group,the calcification group showed significantly increased Runt-related transcription factor 2,bone morphogenetic protein 2,SAT1,calcium content,and alkaline phosphatase activity,while alpha-smooth muscle actin expression was significantly decreased(all P<0.05).Compared with the calcification group,the 50 and 100 μmol/L diacetylaminotriazamidine groups showed significantly decreased Runt-related transcription factor 2,bone morphogenetic protein 2,calcium content,and alkaline phosphatase activity,while alpha-smooth muscle actin expression was significantly increased(all P<0.05).(3)Immunofluorescence experiments demonstrated that compared with the calcification group,the expression intensity of Runt-related transcription factor 2 was significantly reduced in the 50 and 100 μmol/L diacetylaminotriazamidine groups.Overall,SAT1 may promote vascular smooth muscle cell calcification by upregulating Runt-related transcription factor 2 expression.

BACKGROUND:Magnesium and magnesium-based materials have good biocompatibility,stable osteogenic properties,and biological activities such as vascularization and immune regulation,and show a broad application prospect in stomatology.OBJECTIVE:To summarize the mechanism of magnesium-based materials in the treatment of oral diseases in terms of osteogenesis,angiogenesis,and immunomodulation,and to review the application prospects of magnesium and magnesium-based materials in the field of oral diseases in recent years.METHODS:Chinese search key words were"magnesium,magnesium alloys,magnesium-based metals,fractures,implants,restorations,endodontics,periodontitis,periodontal disease,cysts,oral cancer."English search key works were"magnesium,magnesium-based alloy,fracture,facial bone fractures,denture,dental implant,restorative dentistry,pulpitis,periodontitis,periodontal diseases,oral cancer."The articles were retrieved on CNKI,WanFang,PubMed,and Web of Science databases.By analyzing and reading literature for screening,84 articles were finally included for review.RESULTS AND CONCLUSION:Magnesium and magnesium-based materials can be used as bone internal fixation devices for jaw fracture or orthognathic surgery.Due to the special biological properties of magnesium,it can not only ensure stable osteogenesis,but also avoid the possibility of secondary surgery,which has the potential to be widely used.In the field of bone regeneration in stomatology,magnesium,relying on its superior biological properties,shows better mechanical properties and antibacterial properties than existing clinical materials,providing more options for the development and application of materials in this field.With the help of the biological activity of magnesium,magnesium-based coating materials give full play to the anti-inflammatory and antioxidant effects,further promote implant bone bonding and soft tissue integration,and have great application prospects in implant surface modification and promoting implant stability.Although magnesium has been involved in maxillofacial intraoral soft tissue regeneration and treatment,dental tissue engineering,there are still a lot of gaps.To ensure the stable biological characteristics of magnesium,it is usually necessary to add other alloys or carry out magnesium surface modification.However,the biological evaluation system of degradable metal implants is not perfect at present.The clinical application of magnesium in oral diseases still needs to be further clarified in the future.

Objective:To conduct an integrative review of follow-up practices in post-bariatric surgery patients, clarify current follow-up strategies and influencing factors, and provide references for clinical practice and future research.Methods:An integrative review approach was employed. Systematic searches were conducted in PubMed, Web of Science, Cochrane Library, CINAHL, China National Knowledge Infrastructure, Wanfang, and VIP for studies related to post-bariatric surgery follow-up. The search period extended up to December 1, 2024. Data extraction and synthesis were performed by two independent researchers.Results:A total of 30 studies were included, comprising 12 non-randomized quantitative studies, 11 descriptive quantitative studies, three randomized controlled trials, three qualitative studies, and one mixed-method study. Among them, 15 studies explored factors contributing to loss to follow-up, which were mainly categorized into subjective psychological factors, objective barriers, demographic characteristics, and medical-related factors. A total of 12 studies evaluated the effectiveness of various follow-up strategies, showing that telemedicine and IoT-based remote follow-up models could improve patient adherence and reduce the risk of postoperative complications. Additionally, multidisciplinary collaborative models demonstrated superior outcomes in increasing follow-up rates, lowering complication rates, and improving excess weight loss compared to traditional management approaches. The use of financial incentives exhibited short-term effectiveness, with quantitative studies indicating sustained adherence for up to six months; however, qualitative studies suggested that while patients acknowledged financial incentives as a supportive measure, they perceived their impact on long-term motivation to be limited. Furthermore, routine monitoring, continuity of care led by dedicated personnel, and efficient team communication were identified as effective strategies to enhance follow-up adherence and postoperative management.Conclusions:Multiple factors influence follow-up adherence in post-bariatric surgery patients. Technology-driven remote follow-up and personalized support strategies have shown significant advantages in enhancing follow-up rates. Future efforts should focus on standardizing post-bariatric surgery follow-up protocols.

It was a retrospective study. The propensity score matching was applied to divide the type 2 diabetes mellitus (T2DM) patients who have underwent percutaneous coronary intervention (PCI) into two groups: short-term (<4 weeks) sodium-glucose cotransporter 2 inhibitor (SGLT2i) group (213 patients) and control group (213 patients). The occurrence of contrast-induced acute kidney injury (CIAKI) after PCI was compared between the two groups. The results showed that the incidence of CIAKI in the SGLT2i group was not significantly different from the control group [10.8% (23/213) vs. 7.5% (16/213), χ2=1.383, P=0.313]. The incidence of CIAKI in patients with SGLT2i application time <1 week was higher than that in control patients, but the difference was not statistically significant [13.00% (16/123) vs. 7.5% (16/213), χ2=2.734, P=0.122]. Multivariate logistic regression analysis showed that short-term (<4 weeks) use of SGLT2i would not increase the risk of CIAKI after PCI in T2DM patients ( OR=0.507, 95% CI 0.238-1.077, P=0.077). Short-term application of SGLT2i before PCI may not increase the risk of CIAKI, but it is advisable to avoid initiating the application of SGLT2i before PCI as much as possible.

Urinary tract obstruction symptoms as the predominant manifestation of interstitial cystitis/bladder pain syndrome (IC/BPS) are uncommon and can easily be misdiagnosed as bladder neck obstruction, benign prostatic hyperplasia, or prostatitis. This article reports three cases of such patients. Case 1 was a 61-year-old male, case 2 was a 53-year-old female, and case 3 was a 26-year-old male. Cases 1 and 2 were initially suspected of having bladder neck obstruction, and both underwent bladder neck incision, which resulted in poor outcomes. Case 3 was initially diagnosed with chronic prostatitis. All three patients were diagnosed with IC/BPS after undergoing bladder hydrodistention therapy. One patient received intravesical botulinum toxin A injection following hydrodistention. After treatment, the patients were followed up for 4 months, 2.5 months, and 1.5 months, respectively, and all reported satisfactory symptom improvement.

Paraganglioma（PGL）is an extra-adrenal catecholamine-secreting endocrine tumor. We reported a young female patient who was admitted to the hospital with right flank pain and diagnosed with right retroperitoneal PGL with Mayo Ⅳ inferior vena cava tumor thrombus（double tumor thrombus）. After multidisciplinary consultation，right retroperitoneal PGL resection，right nephrectomy，inferior vena cava Mayo Ⅳ tumor thrombus resection and reconstruction were performed. Postoperative pathology showed that the primary tumor and inferior vena cava tumor thrombus was consistent with PGL. Genetic testing revealed a heterozygous germline nonsense mutation at c.69_70delinsTT（p.Q24*）locus of the SDHB gene in the patient. His mother was a carrier of the gene，but his father and sister did not carry the mutation. The patient recovered smoothly after surgery.

Objective:To investigate the influencing factors of the quality of inpatient medical record home page information in public hospitals under the background of the reform of diagnosis related groups(DRG)-based payment system and their mechanisms of action, so as to provide references for continuous improvement of the quality of medical record home page information.Methods:From July to August 2024, semi-structured interviews were conducted with clinical physicians and personnel engaged in the filling, quality control, review, and management of inpatient medical record home pages in public hospitals in Hangzhou, using purposeful sampling. The interview data were qualitatively analyzed based on the grounded theory to identify the influencing factors of the quality of medical record home page information and construct a theoretical model of the mechanisms of action of these factors.Results:Through open coding of the 17 interview materials, 53 initial concepts and 13 categories were identified. Further induction through axial coding led to the extraction of four main categories: external environment, organizational resources, person-job fit, and work ecology. The theoretical model of the mechanisms of action of the influencing factors on the quality of medical record home page information was as follows: external environmental factors such as policies and regulations played a macroscopic guiding role in the quality of medical record home pages; organizational resource factors such as the hospital′s information construction played a mesoscopic regulating role in the quality of medical record home pages; person-job fit factors such as the professional skills of clinical physicians and medical record-related staff played a direct driving role in the quality of medical record home pages; and work ecology factors such as the workload of clinical physicians and medical record-related staff played an external modulating role in the quality of medical record home pages.Conclusions:Under the background of DRG reform, the quality of inpatient medical record home page information was influenced by multiple factors. To systematically improve the quality of medical record home page information, it is necessary for multiple parties to work together. Relevant government departments should improve the top-level design and optimize the external environment, guide and assist medical institutions in building quality control systems, and strengthen resource allocation. Medical institutions should focus on enhancing the job competence and person-job fit of relevant personnel and also use intelligent means to optimize work processes to reduce workload.
