Infection-related glomerulonephritis (IRGN) is an immune-mediated glomerular injury triggered by infectious agents. This article reports a case of immune complex-mediated glomerulonephritis following acute hepatitis B virus infection, which continued to progress despite standard antiviral and immunosuppressive therapy. Given the significant elevation of soluble complement membrane attack complex (sC5b-9), an indicator of terminal complement pathway activation, the patient was treated with eculizumab. Following treatment, the patient's urine protein-to-creatinine ratio significantly decreased, hypoalbuminemia and hematuria markedly improved, and sC5b-9 levels declined. This case suggests that abnormal complement system activation may be a key mechanism driving disease persistence in some patients with IRGN. For those unresponsive to conventional therapy, complement function screening and targeted terminal complement pathway inhibition may represent an effective salvage strategy.

OBJECTIVE:
To analyze the time characteristics of the Ethos online adaptive radiotherapy (OART) process in clinical practice and provide guidance for the comprehensive optimization of each stage of adaptive radiotherapy.
METHODS:
The study involved 61 patients with cervical, rectal, gastric, lung, esophageal, and breast cancers who underwent Ethos OART. The mean ± standard deviation of segmental time, total time, and target volume for these patients were tracked. The time characteristics for different cancer types were evaluated, and the average time for target and organ at risk (OAR) modifications was compared with the average target volume for each cancer type.
RESULTS:
Cervical cancer born the longest total treatment time, while breast cancer had the shortest. For all cancer types except breast cancer, the modification time for target and OAR was the most time-consuming segment. The average time for target and OAR modifications aligned with the trend of the average target volume.
CONCLUSION
The total treatment time for various cancers ranges from 15 to 35 minutes, indicating room for improvement.

Objective:To compare the outcomes of multiple scales, primarily the speech, spatial, and other qualities of hearing scale for parents(SSQ-P), in children with ipsilateral vs. Contralateral cochleareimplantat ion(CRI). Methods: A total of 69 children who received cochlear implantation surgery from April 1999 to June 2024 were included. Patients were divided into two groups based on whether the implantation was on the same side. General information such as gender, age, age at initial implantation and reimplantation was collected. The primary caregivers of the children were followed up by telephone using the categories of auditory performance(CAP), speech intelligibility rating(SIR), and SSQ-P questionnaires. Statistical methods including stepwise regression, linear regression, and permutation tests were employed to investigate if there were any statistically significant differences in the scores of CAP, SIR, SSQ-P total, SSQ-P speech perception, SSQ-P spatial hearing, and SSQ-P auditory quality dimensions between the ipsilateral and contralateral reimplantation groups. Results:Of the 69 children included, 62 were in the ipsilateral reimplantation group with a mean age of 11.1 years, and 7 were in the contralateral reimplantation group with a mean age of 11.7 years. Statistical analysis showed that patients in the contralateral reimplantation group had significantly lower SSQ-P total scores (P<0.05) and spatial hearing dimension scores (P<0.05) than those in the ipsilateral reimplantation group after controlling for the corresponding confounders. Conclusion:The effect of ipsilateral reimplantation of cochlear implants is superior to that of contralateral reimplantation in terms of overall auditory function and spatial hearing in daily life for children, but the mechanisms require further investigation.

In the century-long evolution of insulin pharmaceuticals, each transformative advancement in this drug class has been closely tied to the ability to obtain new insulin isoforms for research. Despite this, the recently discovered naturally occurring isoforms of glycosylated human insulin have remained largely unattainable for proper characterization. Herein, we demonstrate for the first time that total chemical synthesis can be used to generate all isoforms. This achievement required maintaining the correct positions of the interchain disulfide bonds while effectively removing protecting groups on complex glycans. Notably, the availability of seven glycoforms reveals the important effects of natural sialylated glycans in suppressing insulin self-association and enhancing its solubility, surpassing the performance of currently employed rapid-acting insulin drugs. This work not only offers a readily adaptable platform for exploring natural O-glycosylation in other therapeutic proteins and peptides but also lays the groundwork for further research into harnessing natural glycosylation for therapeutic applications.

Objective:To evaluate the clinical efficacy of cannulated screws combined with suture anchor in the treatment of comminuted patellar fractures.Methods:A retrospective study was conducted to analyze the data of 72 patients who had been admitted to Department of Orthopaedics, The Second Hospital of Shanxi Medical University for comminuted patellar fractures between January 2020 and June 2023. The patients were divided into 2 groups based on the surgical techniques used. In group A of 34 patients subjected to fixation using cannulated screws combined with suture anchors, there were 22 males and 12 females with an age of 49 (39, 58) years, and 7 cases of AO type 34-C2 and 27 cases of AO type 34-C3. In group B of 38 patients subjected to fixation using cannulated screws combined with titanium cables, there were 19 males and 19 females with an age of 55 (40, 62) years, and 11 cases of AO type 34-C2 and 27 cases of AO type 34-C3. Comparisons were made between the 2 groups regarding general preoperative data, postoperative range of knee motion, fracture healing time, complications, soft tissue irritation, secondary surgery, postoperative pain assessed by visual analogue scale (VAS), postoperative Bostman knee score, and postoperative Levack knee score.Results:The 2 groups were comparable because there were no statistically significant differences in the general preoperative data and follow-up time between them ( P>0.05). There were no statistically significant differences between the 2 groups either in postoperative range of knee motion, fracture healing time, or Bostman knee score or Levack knee score at the last follow-up (all P>0.05). In group A, the VAS pain score and the rate of soft tissue irritation at the last follow-up were respectively 0.0 (0.0, 1.0) and 0% (0/34), significantly lower than those in group B [1.0 (0.0, 1.3) and 15.8% (6/38)] ( P<0.05). The overall incidence of complications and secondary surgery rate in group A were respectively 5.9% (2/34) and 2.9% (1/34), lower than those in group B [21.1% (8/38) and 15.8% (6/38)], but showing no statistically significant difference between the 2 groups ( P>0.05). Conclusions:In the treatment of comminuted patellar fractures, fixation using cannulated screws combined with both titanium cables and suture anchors can lead to comparable clinical efficacy, but fixation using cannulated screws and suture anchors can reduce soft tissue irritation, alleviate pain, and improve the quality of life of patients.
