Background: Diabetic macrovascular and microvascular complications often coexist and may share similar risk factors and pathological pathways. We aimed to investigate whether 10-year atherosclerotic cardiovascular disease (ASCVD) risk, which is commonly assessed in diabetes management, can predict incident diabetic nephropathy (DN) and retinopathy (DR) in patients with type 2 diabetes mellitus (T2DM). Methods: This prospective cohort study enrolled 2,891 patients with clinically diagnosed T2DM who were free of ASCVD, nephropathy, or retinopathy at baseline in the Guangzhou (2017–2022) and Shaoguan (2019–2021) Diabetic Eye Study in southern China. The 10-year ASCVD risk was calculated by the Prediction for ASCVD Risk in China (China-PAR) equations. Multivariable- adjusted Cox proportional hazard models were developed to estimate hazard ratios (HRs) with 95% confidence intervals (CIs). The area under the receiver operating characteristic curve (AUC) was used to evaluate predictive capability. Results: During follow-up, a total of 171 cases of DN and 532 cases of DR were documented. Each 1% increment in 10-year ASCVD risk was associated with increased risk of DN (pooled HR, 1.122; 95% CI, 1.094 to 1.150) but not DR (pooled HR, 0.996; 95% CI, 0.979 to 1.013). The model demonstrated acceptable performance in predicting new-onset DN (pooled AUC, 0.670; 95% CI, 0.628 to 0.715). These results were consistent across cohorts and subgroups, with the association appearing to be more pronounced in women. Conclusion Ten-year ASCVD risk predicts incident DN but not DR in our study population with T2DM. Regular monitoring of ASCVD risk in routine diabetes practice may add to the ability to enhance population-based prevention for both macrovascular and microvascular diseases, particularly among women.

Accurate segmentation of oral surgery-related tissues from cone beam computed tomography(CBCT)images can significantly accelerate treatment planning and improve surgical accuracy.In this paper,we propose a fully automated tissue segmentation system for dental implant surgery.Specifically,we propose an image preprocessing method based on data distribution histograms,which can adaptively process CBCT images with different parameters.Based on this,we use the bone segmentation network to obtain the segmentation results of alveolar bone,teeth,and maxillary sinus.We use the tooth and mandibular regions as the ROI regions of tooth segmentation and mandibular nerve tube segmentation to achieve the corresponding tasks.The tooth segmentation results can obtain the order information of the dentition.The corresponding experimental results show that our method can achieve higher segmentation accuracy and efficiency compared to existing methods.Its average Dice scores on the tooth,alveolar bone,maxillary sinus,and mandibular canal segmentation tasks were 96.5%,95.4%,93.6%,and 94.8%,respectively.These results demonstrate that it can accelerate the development of digital dentistry.

Background and Objectives: This study aims to clarify the systems underlying regulation and regulatory roles of hydrogen combined with 5-Aza in the myogenic differentiation of adipose mesenchymal stem cells (ADSCs). Methods: and Results: In this study, ADSCs acted as an in vitro myogenic differentiating mode. First, the Alamar blue Staining and mitochondrial tracer technique were used to verify whether hydrogen combined with 5-Aza could promote cell proliferation. In addition, this study assessed myogenic differentiating markers (e.g., Myogenin, Mhc and Myod protein expressions) based on the Western blotting assay, analysis on cellular morphological characteristics (e.g., Myotube number, length, diameter and maturation index), RT-PCR (Myod, Myogenin and Mhc mRNA expression) and Immunofluorescence analysis (Desmin, Myosin and β-actin protein expression). Finally, to verify the mechanism of myogenic differentiation of hydrogen-bound 5-Aza, we performed bioinformatics analysis and Western blot to detect the expression of p-P38 protein. Hydrogen combined with 5-Aza significantly enhanced the proliferation and myogenic differentiation of ADSCs in vitro by increasing the number of single-cell mitochondria and upregulating the expression of myogenic biomarkers such as Myod, Mhc and myotube formation. The expressions of p-P38 was up-regulated by hydrogen combined with 5-Aza. The differentiating ability was suppressed when the cells were cultivated in combination with SB203580 (p38 MAPK signal pathway inhibitor). Conclusions Hydrogen alleviates the cytotoxicity of 5-Aza and synergistically promotes the myogenic differentiation capacity of adipose stem cells via the p38 MAPK pathway. Thus, the mentioned results present insights into myogenic differentiation and are likely to generate one potential alternative strategy for skeletal muscle related diseases.

Objective:The investigation and research on the application status of Hepatic Venous Pressure Gradient (HVPG) is very important to understand the real situation and future development of this technology in China.Methods:This study comprehensively investigated the basic situation of HVPG technology in China, including hospital distribution, hospital level, annual number of cases, catheters used, average cost, indications and existing problems.Results:According to the survey, there were 70 hospitals in China carrying out HVPG technology in 2021, distributed in 28 provinces (autonomous regions and municipalities directly under the central Government). A total of 4 398 cases of HVPG were performed in all the surveyed hospitals in 2021, of which 2 291 cases (52.1%) were tested by HVPG alone. The average cost of HVPG detection was (5 617.2±2 079.4) yuan. 96.3% of the teams completed HVPG detection with balloon method, and most of the teams used thrombectomy balloon catheter (80.3%).Conclusion:Through this investigation, the status of domestic clinical application of HVPG has been clarified, and it has been confirmed that many domestic medical institutions have mastered this technology, but it still needs to continue to promote and popularize HVPG technology in the future.

Objective:To investigate the clinical efficacy of Dog-Bone double button in the treatment of acute acromioclavicular dislocation under shoulder arthroscopy.Methods:A retrospective analysis was conducted of the 20 patients with acute acromioclavicular dislocation who had been treated at Department of Sports Medicine, Northern Jiangsu People's Hospital of Jiangsu Province from November 2018 to December 2020 by Dog-Bone double button under shoulder arthroscopy. They were 11 males and 9 females, aged from 31 to 63 years. Recorded were their visual analogue scale (VAS), Constant-Murley shoulder function score and range of shoulder anteflexion at preoperation and the last follow-up, as well as complications and the X-ray parameters at one month postoperation and the last follow-up [including coracoclavicular distance (CCD), distance between the upper and lower Dog-Bone titanium plates (DDD), angle between the coracoid process tunnel and the tangent line of the superior clavicle (CTCA), and widths of the clavicle tunnel and the coracoid process tunnel].Results:The 20 patients were followed up for 6 to 12 months (average, 10.5 months). Their preoperative VAS score, Constant score, and range of shoulder anteflexion were 3.0 (3.0, 4.0), 57.0 (54.3, 61.5) and 130° (110°, 140°), which were significantly improved to 0 (0, 0.8), 90.0 (86.5, 91.0) and 170° (170°, 180°) at the last follow-up ( P<0.05). Their CCD, DDD, CTCA, and widths of the clavicle tunnel and the coracoid process at one month postoperation were (5.0±1.0) mm, (32.4±3.5) mm, 91.7° (88.5°, 104.9°), 3.0 (3.0, 3.0) mm and 3.0 (3.0, 3.0) mm, which were significantly improved to (6.3±1.3) mm, (32.8±3.7) mm, 84.8° (81.8°, 92.0°), 3.5 (3.4, 3.6) mm and 3.2 (3.1, 3.3) mm with the exception of DDD at one month postoperation ( P<0.05). The last follow-up observed postoperative reduction loss in only one patient. Conclusion:For acute acromioclavicular joint dislocation, the Dog-Bone fixation technique under shoulder arthroscopy can lead to fine surgical efficacy and patient satisfaction, because it has advantages of limited trauma, good functional recovery of the shoulder, and effective prevention of reduction loss.

Objective To investigate the clinical efficacy and prognostic factors for combined caudate lobectomy radical resection plus broad lymph node dissection in patients of hilar cholangiocarcinoma.Methods The clinical data and follow-up results of patients with hilar cholangiocarcinoma surgically treated from Feb 2008 to Feb 2017 were retrospectively analyzed.Result The R0 resection rate[72.2％ (13/18) vs 43.9％ (18/41)],operation time [(433 ± 136) min vs (302 ± 122) min],intraoperative blood loss [(1 789 ± 1 091) ml vs (776 ± 755) ml] and postoperative complication rate [66.7％ (12/18) vs 36.6％ (15/41)]were significantly higher in the hepatic lobe combined with caudate lobe resection group than that without caudate lobe resection group (P ＜ 0.05).The median survival time of patients with enlarged lymph node dissection was longer than that of patients with regional lymph node dissection (33 months vs 13 months,P ＜0.05).Univariate and multivariate analysis showed that the preoperative serum CA199 level ＞ 1 000 U/ml,the degree of microscopic margin and tumor TNM stage were significantly correlated with the prognosis of the patients (P ＜ 0.05).Conclusion Combined with caudate lobe resection can improve R0 resection rate.Targeted lymph node dissection helps prolong survival.The degree of microscopic margin,preoperative CA199 and TNM staging are independent risk factors for the prognosis of patients with hilar cholangiocarcinoma.
