ABSTRACT
OBJECTIVE@#To evaluate the value of serum free light chain (sFLC) κ/λ ratio (sFLCR) on the diagnosis and prognosis of patients with newly diagnosed multiple myeloma(MM), and explore the effect of sFLCR normalization on the prognosis of patients after 4 courses of induction therapy.@*METHODS@#The clinical data of 43 newly diagnosed MM patients from January 2014 to January 2019 were analyzed retrospectively. Immunoturbidimetry was used to detect the expression levels of sFLC κ and λ. According to the ratio of involved and uninvolved sFLC, using 100 as a boundary, the MM patients were divided into the high ratio group (sFLCR≥100 or ≤0.01) and the low ratio group (0.010.05).@*CONCLUSION@#Patients in the high ratio group at the initial diagnosis have worse renal function, later stage of disease, lower deep remission rate, earlier disease progression, shorter survival time, and worse clinical prognosis.

Aim The effects of antibiotics and anticoagulants on mouse peritonaeum were ob-served to explore the factor of the peritoneal dialysis related sclerosing peritoni-tis. Methods The experimental models of peritoneal dialysis were established in miceby infusing different kind of drugs to the peritoneal cavity and the changes of the peri-toneal membrane for each drug at different time were observed by the autopsy and lightmicroscope for several weeks. Results Amikacin, Cefradine, Zinacef, Ciprofloxacin,Heparin and Urokinase could induce sclerosing changes of peritoneal membrane such asloss of peritoneal mesothelum infiltration of inflammatory cells and of proliferation fibrecell.These changes were irreversible after the drugs were stoped.Conclusion Thedrugs commonly used in peritoneal dialysis may in different degree result in peritonealsclerosis.
