Objective:To evaluate the clinical efficacy and safety of sulodexide soft capsules in treating proteinuria after renal transplantation, as well as its impact on graft function.Methods:The clinical data from 80 recipients who developed proteinuria after renal transplantation and were treated with sulodexide soft capsules during regular follow-up at the outpatient department of Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from March 1, 2019, to March 1, 2023, were retrospectively analyzed. Proteinuria levels, graft function, safety-related indicators (coagulation function), and adverse events were compared before treatment and at 1, 2, 3, 6, and 12 months after treatment. Based on efficacy, recipients were divided into a satisfactory efficacy group (67 cases) and a general efficacy group (13 cases). Univariate and multivariate logistic regression analyses were conducted to stratify baseline data and explore factors influencing efficacy.Results:Among the 80 recipients, 63 (78.75%) had mild proteinuria and 17 (21.25%) had moderate proteinuria. The overall treatment response rate was 91.25% (73/80). Drug-related adverse events occurred in 12 patients (15.0%). Median urinary protein excretion at 1, 2, 3, 6, and 12 months post-treatment was 0.35 (0.20, 0.55) g/24 h, 0.30 (0.17, 0.44) g/24 h, 0.23 (0.15, 0.39) g/24 h, 0.21 (0.13, 0.32) g/24 h, and 0.15 (0.10, 0.23) g/24 h, respectively, all significantly lower than the pre-treatment level of 0.52 (0.43, 0.90) g/24 h (all P<0.001). The median urinary albumin-to-creatinine ratios at the corresponding time points were 99.15 (45.33, 201.13) μg/mg, 77.20 (43.30, 176.20) μg/mg, 57.50 (31.35, 173.75) μg/mg, 53.55 (25.90, 142.00) μg/mg, and 39.05 (20.53, 103.60) μg/mg, also significantly reduced compared to the pre-treatment value of 152.05 (71.90, 271.23) μg/mg ( P=0.012, P=0.003, P<0.001, P<0.001, P<0.001, respectively). At 12 months post-treatment, the serum creatinine level (132.86±36.86 μmol/L) showed a statistically significant improvement compared to the pre-treatment level (146.60±48.42 μmol/L) ( P=0.045). Univariate analysis indicated that satisfactory efficacy was associated with the time of proteinuria onset post-transplantation, the interval between proteinuria onset and treatment initiation, and recipient age ( HR= 1.001, 95% CI: 1.001-1.020, P=0.043; HR = 1.034, 95% CI: 1.009-1.058, P=0.006; HR=1.058, 95% CI: 1.003-1.116, P=0.040). Stratified univariate analysis revealed that proteinuria onset within 2 years post-transplantation, treatment initiation within 2 years of proteinuria onset, and age younger than 45 years were significantly associated with satisfactory efficacy ( HR=5.524, 95% CI: 1.510-20.207, P=0.010; HR= 7.800, 95% CI: 2.104-28.920, P=0.002; HR=5.972, 95% CI: 1.497-23.822, P=0.011). Multivariate analysis identified the interval between proteinuria onset and treatment initiation as an independent factor influencing satisfactory efficacy ( HR=1.025, 95% CI: 1.010-1.093, P=0.015). Conclusions:Sulodexide effectively reduces proteinuria after renal transplantation, particularly in mild-to-moderate or early-onset cases, while maintaining stable allograft function without significant adverse effects

Tooth autotransplantation is a restoration technology that grafts the patient's own teeth to the missing tooth area, usually by using the third molar to replace a nonnormally functioning molar for the purpose of "turning waste into treasure". Robotic surgical assistance has been widely used in the fields of breast cancer, liver cancer, and orthopedics; however, its application in the dental field, particularly in tooth autotransplantation, remains relatively rare. This paper reports a case of tooth autotransplantation with the assistance of a domestic autonomous oral surgery robot, providing a reference for the application of robotic surgery assistance in tooth autotransplantation.

To address the limitations of traditional minimally invasive thermal ablation technology such as poor conformability, carbonization and electromagnetic radiation, this paper proposes a steam thermal ablation technology that uses saturated steam internal energy to replace the traditional electromagnetic radiation energy. Through the steam thermal ablation system and the steam thermal ablation needle designed based on simulation, the ex vivo pig liver experiments were carried out. The results have the characteristics of the maximum ablation axis ratio (short diameter / long diameter) and non-carbonization with the same type of thermal ablation technology. Based on the near-infrared light, in this paper the curative effect of the reduced scattering coefficient of the steam thermal ablation results was evaluated. The reduced scattering coefficients of the coagulation area all exceeded 16, reaching the completely damaged state, which verified that the steam thermal ablation can effectively inactivate the tumor cells.

The minimally invasive thermal ablation technology differs from traditional surgical operations, which requires auxiliary equipment to evaluate ablation results. However, the ultrasound and CT currently used in clinical practice have shortcomings such as artifacts and radiation. Therefore, this paper proposes a design for a minimally invasive thermal ablation evaluation system based on the principle of electrical impedance tomography technology to monitor the ablation range. At the same time, the innovative introduction of a programmable gain feedforward signal as the parameter signal of the multiplier demodulator in the electrical impedance tomography system design can effectively solve the problem of weak signals being submerged in noise and improve imaging accuracy. The system controls the amplitude of the excitation current signal and the acquisition / processing of boundary voltages via an STM32, uploads the collected data to an upper computer, and reconstructs the conductivity distribution using the Newton-Raphson algorithm to map the size of the ablation area. Experimental results show that the system can effectively reflect the size of the microwave ablation area. Under the same minimally invasive ablation parameters, the average imaging errors are 0.6 mm for the long diameter, 0.8 mm for the short diameter, and 1.75% for the axial ratio (long diameter / short diameter), demonstrating high consistency. This verifies the technical potential of electrical impedance tomography in minimally invasive thermal ablation.

Biological age (BA) is a marker to accurately assess aging, facilitating the prediction of age-related diseases and promoting healthy aging. In recent years, first- and second-generation organ-system-specific BA has been developed using chronological age (CA) or aging-related outcomes (mortality) as training phenotypes and data from questionnaires, physical examinations, clinical biochemistry, imaging, and multi-omics to investigate the specificity of organ systems aging. Here, we review the methodologies for constructing BA, current efforts to assess organ system-specific BA, and related genome-wide association studies (GWAS). Previous studies predominantly used the first-generation BA method, using CA as training phenotypes. Organ-system-specific BA can accurately predict the disease risk of corresponding organ systems. We propose the development of organ system-specific BA through second-generation BA models and conducting GWAS and Mendelian randomization studies to explore organ system-specific aging processes, which will provide a theoretical foundation for the clinical application of organ system-specific BA.
