Objective In this study, by the established HEK293T cell line with stable expression of human platelet CD36, murine anti-human CD36 monoclonal antibody was prepared and characterized. Methods The established HEK293T cell line with stable expression of human platelet CD36 was used to immunize CD36 (-/-) C57 mice, and the spleen was fused with mouse myeloma cells to screen for positive cloning.After the purification of monoclonal antibody, the antibody binding activity was detected by Western blot.Mouse rapid antibody isotyping reagent was used to identify the subtype of monoclonal antibody.Its diagnostic value was evaluated by flow cytometry and monoclonal antibody-specific immobilization of platelet antigen (MAIPA). Results After screening, a high-producing hybridoma cell was obtained, the subtype of monoclonal antibody was IgG2a and the light chain was κ chain. Western blot analysis showed that the monoclonal antibody could specifically recognize CD36 antigen of human platelet. MAIPA results showed that the monoclonal antibody was more sensitive than the commercial monoclonal antibody FA6-152.

Objective To explore quality of life and its risk factors in patients with refractory irritable bowel syndrome(RIBS). Methods 601 IBS patients in gastroenterology clinic and 100 healthy volunteers were invited to complete irritable bowel syndrome- symptom severity scale (IBS-SSS), the Hamilton Rating Scale of Anxiety/ Depression (HAMA/HAMD), Irritable bowel syndrome-quality of life(IBS-QOL). And multiple linear regression analysis was used to explore the determinants of quality of life in patients with RIBS. Results The overall score and subscale scores of IBS-QOL in RIBS group were lower than those in the non-RIBS and healthy group (P<0.05). There were no significant differences in the overall scores of IBS-QOL among different subtypes of RIBS. However, the interference with activities, health anxious, social reaction scores were different among the subtypes (P<0.05). Multiple linear regression analysis demonstrated that quality of life in RIBS was independently associated with the scores in IBS-SSS and HAMA. Conclusion Quality of life in RIBS is obviously decreased. Quality of life in RIBS is closely related to clinical symptoms and anxiety condition.
