AIM: To analyze T cell clonality in patients with T cell acute lymphoblastic leukemia (T-ALL). METHODS: The complementarity determining region 3 (CDR3) size of 24 T cell antigen receptor variable β (TCR Vβ) region gene was analyzed in peripheral blood mononuclear cell (PBMC) samples from 6 T-ALL cases and 10 normal individuals by using reverse transcriptase-polymerase chain reaction (RT-PCR). The PCR products were further studied by genescan and sequencing analysis. RESULTS: Some TCR Vβ subfamily T cells display mono- or oligoclonal expansions in 3 cases of T-ALL, predominantly in Vβ2, Vβ3, Vβ6, Vβ9, Vβ21 or Vβ24, respectively. Polyclonal expansions of T cells were found in the other three cases, which could also be found in normal samples. CONCLUSION: A part of T cell acute lymphoblastic leukemia cells may arise from a clonal expansion of TCR Vβ subfamily T cell. This method may be useful for the detection of minimal residual disease in clinical study of the disease.

Objective:To analyze influencing factors for sarcopenia in people of advanced age, in order to provide insight and evidence for the prevention and treatment of sarcopenia in people belonging to this age group.Methods:Data from 167 people of advanced age seeking care at our department from December 2014 to July 2017 were retrospectively analyzed.According to the diagnostic criteria for sarcopenia of the Asian Working Group for Sarcopenia, subjects were divided into the sarcopenia group( n=46, 27.5%)and the non-sarcopenia group( n=121). Differences in body composition, energy intake, quantities and proportions of three major nutrients were analyzed between males and females.Related influencing factors for sarcopenia were analyzed by using multiple linear regression. Results:Compared with the non-sarcopenia group, the sarcopenia group had lower body mass index, waist-hip ratio, fat mass, total energy intake and protein( P<0.05)but higher age and fat intake( P<0.05). Values for grip strength, muscle mass, index of skeletal muscle, adjusted muscle mass by body mass index, total energy intake, carbohydrates, fat and protein were lower and the percentage of body fat was higher in females than in males( P<0.05). Multiple Logistic regression analysis showed that insufficient intake of protein( β=-0.290, OR=0.748, 95% CI: 0.569-0.984, P<0.05), reduction of body fat mass( β=-2.673, OR=0.069, 95% CI: 0.010-0.488, P<0.05)and excessive visceral fat accumulation( β=0.739, OR=2.094, 95% CI: 1.219-3.597, P<0.01)were correlated with sarcopenia in people of advanced age. Conclusions:The occurrence of sarcopenia is higher in people of advanced age and is related to insufficient intake of protein, reduction of body fat mass and excessive visceral fat accumulation.Individualized nutrition evaluation and support should be carried out as early as possible for people in this age group.

Objective:To investigate the muscular quality and its related influencing factors in elderly with sarcopenic obesity.Methods:The internalized 696 elderly subjects meeting inclusion and exclusion criteria were divided into four groups including the sarcopenic obesity(n=55), sarcopenia(n=8), simple obesity(n=481)and normal control(n=152)groups.The intergroup difference was retrospectively analyzed in the parameters of body composition, dietary intake of total energy and three major nutrients and their proportions.Multiple linear regression analysis was used to analyze the influencing factors related to the occurrence of sarcopenic obesity in the elderly.Results:The sarcopenic obesity group versus normal control group showed a higher level or value in age, body mass index, waist-hip ratio, fat mass, percentage of body fat, visceral fat area, fasting blood glucose, estimated glomerular filtration rate( P<0.01 or 0.05), and showed a lower level or value in grip strength, skeletal muscle, skeletal muscle index, muscle quality(grip strength/limb skeletal muscle), intake of energy, carbohydrate, fat and protein, body weight-adjusted intake of energy and protein, as well as ideal body weight-adjusted intake of energy and protein( P<0.01). The detection rate of sarcopenic obesity was 7.90%(n=55), including 7.60% in males(n=48)and 11.48% in females(n=7 cases). The detection rate of sarcopenic obesity was increased along with increasing age with 0.07%(2/287)in 60-69 years old group, 4.94%(12/243)in 70-79 years old group, and 24.70%(41/166)in ≥80 years old group( χ2=87.76, P<0.01). Taking the median point of grip strength/limb skeletal muscle volume as the cutoff point, the decrease rate of muscle quality was 12.36%(86/696)in total elderly subjects, 2.63%(4/152)in the control group, 11.64%(86/635)in the obesity group, 37.5%(3/8)in the sarcopenia group and 41.82%(23/55)in the sarcopenic obesity group, with an increasing trend of the decrease of muscle quality, which had significant differences( χ2=62.25, P<0.01). Multiple logistic regression analysis showed that aging, excessive visceral fat area, insufficient protein intake and decreased basal metabolism were the independent risk factors for sarcopenic obesity in elderly people( P<0.01 or P<0.05). Conclusions:The incidence of decrease of muscle quality is higher in the elderly with sarcopenic obesity than other elderly groups.Sarcopenic obesity is correlated with aging, insufficient intake of protein, decreased basal metabolism and excessive visceral fat accumulation.Individual evaluation and support is necessary in elderly people with sarcopenic obesity.
