Objective To evaluate the reliability of axial view of patella with the knee joint flexed at 60 and 90 degrees on imaging diagnosis of patellar subluxation with DR (digital radiography). Methods 60 cases confirmed patella subluxation were reviewed retrospectively. In addition to routine anteroposterior and lateral DR views, axial DR views of patella with the knee flexed at 60 degrees and 90 degrees were taken meanwhile. Results Of the 60 cases, 45 failed to provide any patellar problems, while the other 15 cases revealed suspicious imaging view of patella subluxation in their normal AP and lateral DR views. In the axial DR views of patella with the knee flexed at 60 degrees and 90 degrees, 50, 4 and 6 cases revealed subluxation, suspicious subluxation and normal alignment of patella. Conclusion Axial DR view of patella with the knee joint flexed at 60 and 90 degrees could provide helpful roentgenographic information in determining the existence of patella subluxation.

Membranous nephropathy (MN) is a type of glomerular disease characterized by diffuse thickening of glomerular basement membrane with subepithelial immune complex deposition, and traditional diagnosis of MN mainly relies on the pathological results of renal biopsy. In recent years, the emergence of biomarkers related to MN such as phospholipase A2 receptor and thrombospondin type-1 domain-containing 7A has changed the diagnosis and treatment mode of MN, providing a new basis for the diagnosis, treatment and prognosis of MN. MN patients with positive specific target antigens exhibit different clinical manifestations and prognoses. Specific target antigens can not only guide diagnosis, but also has predictive value for prognosis. Immunosuppressive therapy is a common treatment for idiopathic MN patients, and the emergence of novel medications such as biologics represents a advance in the treatment of MN, providing a broader array of options for managing the condition. Conversely, the treatment approach for secondary MN primarily targets the management of the primary disease. Based on multiple and new literature, we reviewed the researches progress of target antigens and immunosuppressive therapy related to MN, so as to provide references for clinical diagnosis and treatment of MN.

It was a single-center cross-sectional study to investigate the association of serum C3 level with blood pressure and estimated glomerular filtration rate (eGFR) in patients with idiopathic membranous nephropathy (IMN). The clinical and pathological data of 98 patients with IMN diagnosed by renal biopsy in the Department of Nephrology of East Hospital Affiliated to Tongji University from August 1, 2018 to October 31, 2023 were retrospectively analyzed. The demographic characteristics, serum complement C3 and other clinical data were compared between the non-hypertension group ( n=37) and hypertension group ( n=61). Pearson or Spearman correlation analysis method was used to analyze the correlation between serum C3 and eGFR in IMN patients and IMN patients with hypertension. Multiple linear regression analysis was used to analyze the related factors of eGFR in IMN patients with chronic kidney disease stage 1-3 in hypertension group. The results showed that compared with the non-hypertension group, the patients in hypertension group were older, and had higher levels of serum creatinine, cystatin C, urinary microalbumin to creatinine ratio, serum C3 and C4, and lower eGFR (all P<0.05). The correlation analysis showed that there was no correlation between serum C3 level and eGFR in IMN patients ( r=0.118, P=0.247). However, serum C3 level was positively correlated with eGFR in IMN patients with hypertension ( r=0.325, P=0.011). Multiple linear regression analysis showed that eGFR was negatively correlated with age ( β=-0.328, P=0.013), and positively correlated with serum C3 level ( β=0.228, P=0.048). The study shows that serum C3 level in hypertension group is higher than that in non-hypertension group in IMN patients. Moreover, serum C3 is positively correlated with eGFR.
