ABSTRACT
Objective:To improve awareness of the diagnosis and treatment of splenic histiocytic sarcoma.Methods:The clinical data of one patient with splenic histiocytic sarcoma who was admitted to First Teaching Hospital of Tianjin University of Traditional Chinese Medicine in July 2020 were retrospectively analyzed, and the relevant domestic and foreign literature was reviewed.Results:The patient was diagnosed as splenic histiocytic sarcoma by histopathological and immunohistochemical examinations. The methylprednisolone combined with cyclosporine was ineffective. The patient received a total splenectomy, followed by chemotherapy with VECD and CHOP regimens. The patient's condition was stable during the 5-month follow-up after the operation. The result of bone puncture showed that there was no infiltration of histocytic sarcoma, and hematological remission was obtained.Conclusions:Splenic histocytic sarcoma is a highly malignant tumor with insidious onset, unclear pathogenesis, and lack of specificity in clinical manifestations and imaging examinations. The diagnosis depends on pathological biopsy and immunohistochemistry, and needs to be differentiated from other malignant tumors of lymphoid hematopoietic tissue. At present, there is no best treatment for splenic histiocytic sarcoma, and most patients have a poor prognosis.
ABSTRACT
Objective@#To report 3 cases of multiple myeloma (MM) with lung cancer.Combined with literature review to improve the understanding of MM with lung cancer.@*Methods@#The clinical characteristics, treatment and prognosis of 3 cases of MM with lung cancer in Shijingshan Teaching Hospital of Capital Medical University from January 2017 to December 2018 and the relevant literature were retrospectively reviewed.@*Results@#Among the 3 patients, 2 cases were male and 1 case was female, with an average age of 69.7 years.The pathological type of lung cancer patients was adenocarcinoma, of which 2 cases were positive for EGFR gene mutation and 1 case was positive for ALK fusion gene.Three cases of multiple myeloma were all IgG-kappa light chain type, with stage Ⅲ A. The chemotherapy regimens used in MM patients were all PD regimen 4-6 cycles; one patient died of pulmonary infection, one patient had MM CR, but lung cancer progressed, one patient had MM very good partial remission (VGPR), and there was no recurrence of lung cancer.@*Conclusion@#The pathogenesis of second primary malignancy in MM is not clear, which needs further study.

ABSTRACT
Objective To explore the effect of oral-muscle biofeedback system training on the rehabilitation of cognitive dysfunction in patients with obstructive sleep apnea (OSA) after ischemic stroke.Methods A total of 60 cases of poststroke OSA patients with cognitive dysfunction admitted to the rehabilitation center of deAn hospital in changzhou city from June 2017 to March 2018 were selected.On the basis of routine rehabilitation treatment,the control group was given positive pressure ventilation treatment,and the observation group was given oral muscle biofeedback system training.The changes of polysomnography (PSG) parameters,Montreal cognitive assessment (MoCA) score,serum matrix metalloproteinase-9 (MMP-9) and plasma homcysteinemia (Hcy) expression levels in the two groups before and after treatment were compared.Results Apnea hypopnea index and maximum apnea time of the two groups were significantly decreased after treatment compared with those before treatment,and the lowest SpO2 and average SpO2 were significantly higher than those before treatment(P＜0.05).After treatment,MoCA total score and the dimensions score of patients in the observation group were significantly higher than those in the control group at the same time (P＜0.05).After treatment,the levels of Hcy((12.38±4.54) μmol/L) and MMP-9((124.52± 12.94) μg/L) in the observation group were significantly lower than those in the control group at the same time(Hcy(17.52±6.27) μmol/L,MMP-9(268.25±20.5 7)μg/L),and the difference was statistically significant (Hcy:t=3.637,P＜0.05;MMP-9:t =32.395,P＜0.05).Conclusions Positive pressure ventilation and oral muscle biofeedback system training have the same effect on OSA after stroke,but oral muscle biofeedback system training can also effectively improve patients' cognitive function.
