Levels and Clinical Significances of sPD-1 and sPD-L1 in Peripheral Blood of Lymphoma Patients / 中国实验血液学杂志

OBJECTIVE@#To observe the levels of soluble programmed cell death protein 1 (sPD-1) and soluble programmed cell death ligand 1 (sPD-L1) in peripheral blood of lymphoma patients, and reveal their clinical significances.@*METHODS@#The peripheral blood specimens and clinical data of 64 newly diagnosed lymphoma patients and 30 healthy volunteers were collected. The levels of sPD-1 and sPD-L1 were detected by enzyme-linked immunosorbent assay (ELISA), and their correlations with clinical characteristics of the patients including pathological type, stage, lactate dehydrogenase (LDH) level, T cell subsets were analyzed.@*RESULTS@#The levels of both sPD-1 and sPD-L1 in peripheral blood of lymphoma patients were higher than those of normal controls (P <0.05). There were no significant differences in sPD-1 and sPD-L1 levels in peripheral blood between Hodgkin lymphoma and non-Hodgkin lymphoma patients. Different pathological subtypes of lymphoma had different levels of sPD-1. The level of sPD-1 in patients with T-cell lymphoma was higher than that in patients with B-cell lymphoma (P =0.001). The levels of both sPD-1 and sPD-L1 in patients with Ann Arbor stage III and IV were higher than those in patients with stage I and II (P <0.05). The level of sPD-L1 in patients with abnormally increased LDH was higher than that in patients with normal LDH (P =0.001), but there was no significant difference in sPD-1 level. T cell subset analysis showed that the level of sPD-L1 was negatively correlated to CD4+ T cell content (r =-0.265).@*CONCLUSION@#The levels of sPD-1 and sPD-L1 in peripheral blood of lymphoma patients are related to the pathological type, Ann Arbor stage, LDH content and T cell subsets, and will be potential biomarkers in predicting the prognosis of lymphoma.

Analysis on detection situation of motor cognitive risk syndrome and risk factor / 中华老年医学杂志

Objective:To investigate the detection rate of motoric cognitive risk(MCR)syndrome and explore the possible risk factors at different age groups.Methods:A total of 561 patients from geriatric outpatient clinic of Hubei Provincial Hospital of Traditional Chinese Medicine from November 2018 to December 2019 were divided into two age groups under 70 years old(n=241)and 70 years old and above(n=320). The general information, Pittsburgh Sleep Quality Index, Geriatric Depression Scale-15(GDS-15), 4-meter walking test, Mini-Mental State Examination and Morse Fall Scale were collected.Patients with MCR were screened out according to the MCR diagnostic criteria.Logistic multiple regression analysis was used to analyze the associated risk factors.Results:7 cases(7/241, 2.9%)met the MCR diagnostic criteria in age<70 years group, and 34 cases(34/320, 10.7%)in age ≥ 70 years group.The proportion of hearing impairment complaints and GDS-15 scores of MCR patients were higher than those of the non-MCR group in age<70 years group, and the Morse Fall Scale of MCR patients was higher than that of the non-MCR group in age ≥70 years old group( P<0.05). After adjusting for associated confounding factors, multiple logistic regression analysis showed that hearing impairment complaints( OR=26.394, P<0.05)and GDS-15( OR=1.385, P<0.05)were independent risk factors for MCR in age<70 years group.And female( OR=0.445, P<0.05)was a protective factor for MCR in age ≥70 years old group. Conclusions:Motoric cognitive risk syndrome has different risk factors in different age groups, which may indicate that the causes and predictive significance of MCR in these two different age groups are different.

Analysis of 64 slice spiral CT efficiency of grade three hospitals / 中国医学装备

Objective:Through the analysis of the 64 rows of 128 slice spiral CT two years usage data, establishes CVP analysis model.Methods: Using the rate of return on investment, the investment recovery period, cost recovery rate, the amount of profit, data analysis method, etc.Results: Comprehensive embodiment of equipment through various analysis methods of operation efficiency, to use department and management department to provide relevant data, and provide reference for the rational use of equipment.Conclusion: Through the large medical equipment benefit analysis, can make the hospital more clear understanding of medical equipment to hospitals with economic benefits, so as to improve the efficiency in the use of equipment, reduce the waste of money.

Differences of clinical trails on domestic and international treatment of knee osteoarthritis with acupuncture / 中国针灸

Literatures on knee osteoarthritis treated by acupuncture both in China and abroad published in the mainstay periodicals in recent 10 years were selected, and analyses were done in the following aspects: (1) Randomization, (2) Control group, (3) Sample size, (4) Intervention measurements, (5) Intervention periods, (6) Evaluation on therapeutic effects, (7) Follow-up assessment, (8) Adverse effects, (9) Ratio of the lost case. The result indicates that differences can still be found on the trial designation in China and abroad. The domestic research design should be more comprehensively and strictly.
