To explore the diagnostic value of 75 commonly used clinical laboratory markers for differentiation of traditional Chinese medicine syndromes such as liver and gallbladder damp-heat and liver depression and spleen deficiency in patients with chronic hepatitis B.

OBJECTIVETo study the significance of trace immunoglobulin M (IgM) deposits in glomerular mesangium in children with minimal change primary nephrotic syndrome (PNS).

METHODSOne hundred and six children who were clinically diagnosed with PNS and pathologically diagnosed with minimal change disease (MCD) and trace deposition of IgM in renal tissues were enrolled as subjects. Eighty-one PNS children with MCD but no deposition of immune complexes were used as the control group. The clinical characteristics and efficacies of glucocorticoids and immunosuppressants were retrospectively analyzed in the two groups. All patients were given full-dose prednisone by oral administration, and patients with glucocorticoid resistance or frequent relapses were additionally given immunosuppressants.

RESULTSThe incidence of glucocorticoid resistance in the IgM deposit group was significantly higher than that in the control group (27.2% vs 12.3%; P<0.05). The incidence of frequent relapses in the IgM deposit group was also significantly higher than that in the control group (48.1% vs 10.4%; P<0.05). The complete remission rate for glucocorticoid-resistant patients treated with prednisone combined with mycophenolate mofetil (MMF) was 68% and 62% respectively in the IgM deposit and control groups (P>0.05). The relapse frequency in patients with frequent relapses was significantly reduced in both groups after treatment with prednisone and MMF in combination (P<0.05).

CONCLUSIONSTrace deposition of IgM in renal tissues may be an important factor for glucocorticoid resistance and frequent relapses in PNS children with MCD. Prednisone combined with MMF may be a better choice in the treatment of patients with glucocorticoid resistance or frequent relapses.

ObjectiveTemporal heterogeneity in lung cancer presents as fluctuations in the biological characteristics, genomic mutations, proliferation rates, and chemotherapeutic responses of tumor cells over time, posing a significant barrier to effective treatment. The complexity of this temporal variance, coupled with the spatial diversity of lung cancer, presents formidable challenges for research. This article will pave the way for new avenues in lung cancer research, aiding in a deeper understanding of the temporal heterogeneity of lung cancer, thereby enhancing the cure rate for lung cancer. MethodsRaman spectroscopy emerges as a powerful tool for real-time surveillance of biomolecular composition changes in lung cancer at the cellular scale, thus shedding light on the disease’s temporal heterogeneity. In our investigation, we harnessed Raman spectroscopic microscopy alongside multivariate statistical analysis to scrutinize the biomolecular alterations in human lung epithelial cells across various timeframes after benzo(a)pyrene exposure. ResultsOur findings indicated a temporal reduction in nucleic acids, lipids, proteins, and carotenoids, coinciding with a rise in glucose concentration. These patterns suggest that benzo(a)pyrene induces structural damage to the genetic material, accelerates lipid peroxidation, disrupts protein metabolism, curtails carotenoid production, and alters glucose metabolic pathways. Employing Raman spectroscopy enabled us to monitor the biomolecular dynamics within lung cancer cells in a real-time, non-invasive, and non-destructive manner, facilitating the elucidation of pivotal molecular features. ConclusionThis research enhances the comprehension of lung cancer progression and supports the development of personalized therapeutic approaches, which may improve the clinical outcomes for patients.
