ObjectiveTo evaluate the relationship between the level of thoracic complete spinal cord injury(SCI) and ambulatory function wearing Reciprocating Gait Orthosis(RGO) through three dimentional gait analysis, and to explore the quantitative indicators of reconstructing walking capacity of thoracic complete SCI patients.Methods10 patients with thoracic complete spinal cord injury of lesion level from T4 to T12 who had experienced RGO gait training for at least 3 months. Three dimentional gait analysis system of Vicon Nexus 1.2 was used to test and examine the gait speed, cadence, stride length, pelvic angle of rotation, hip range of motion(ROM), crutch force, angular velocity of hip flexion and extension phases, etc. Pearson's product moment correlation coefficient and Spearman rank correlation coefficient were used to examine the relationship between the level of spinal cord injury and the kinematic and kinetic values.ResultsThe mean cadence and stride length were (37.4±2.15) steps/min and (91.6±9.09) cm. The mean hip ROM, angular velocity of hip flexion and extension phases were (42.57 °±5.43 °), (20.88 °±2.18 °)/s and (124.75 °±9.31 °)/s respectively. The gait speed, stride length, peak crutch force, hip ROM, mean crutch force and angular velocity of hip extension phase all had significant pertinence with the level of spinal cord injury.ConclusionThe limitation of hip ROM and excessive load of upper limbs mainly result in ambulatory disorder in higher thoracic complete SCI patients who should be undertaken some rehabilitation training to reduce excessive physiological load in order to improve their ambulatory capacity.

Objective:To investigate the characteristics of changes in peripheral blood regulatory T lymphocyte (Treg) levels in patients with B-cell lymphoma who received chimeric antigen receptor (CAR)-T cell immunotherapy, and the relationship between Treg levels and optimal efficacy and treatment response.Methods:The data of 23 patients with relapsed/refractory B-cell malignancies who received CD19/CD22 CAR-T cell immunotherapy in Wuhan Tongji Hospital from 2019 to 2021 were retrospectively studied. The enrolled patients were divided into complete remission (CR) group (8 cases), partial remission (PR) group (7 cases) and no response(NR) group (8 cases) according to Lugano′s revised lymphoma efficacy evaluation criteria. A total of 16 patients with B-cell lymphoma who did not receive CAR-T cell immunotherapy during the same period in Wuhan Tongji Hospital were collected as the control group.In different periods during CAR-T cell immunotherapy, multicolor flow cytometry(MFC) was used to dynamically detect peripheral blood the proportion of Treg in CD4 +T cells (Treg/CD4 +T), the proportion of lymphocytes (Treg/Lym), the proportion of Treg in white blood cells (Treg/WBC), and the absolute number of Treg (Treg#). The trend of Treg levels over time, as well as the differences in Treg levels in patients with different prognosis groups in different periods were analyzed.According to the proportion of Treg and the median level of absolute number within 1 to 15 days after CAR-T cell infusion, the patients were divided into a low-level group with 11 cases and a high-level group with 12 cases. The statistical differences in the peak value of CAR-T copy, iron protein, and IL-6 were compared between various groups. Independent samples t test, Mann-Whitney U test, Cox-Stuart trend existence test and one-way analysis of variance was used in statistical analysis. Results:In the 23 patients who received CAR-T cell immunotherapy, the mean values of Treg/CD4 +T and Treg/Lym before CAR-T cell infusion were (20.42±7.96)% and (13.61±7.13)%, respectively, which were significantly higher than that of the control group [(7.33±3.61)%, t=5.893, P<0.001; (1.91±0.90)%, t=6.53, P<0.001]. The number of Treg in the meantime was significantly lower [(1.81±1.52)/μl<(13.66±9.89)/μl, t=4.261, P<0.001]. After infusion, Treg/CD4 +T and Treg/Lym all remarkably decreased ( P<0.001),Treg/WBC increased significantly( P=0.01). The mean values of Treg/CD4 +T (12.87±1.93)%, Treg/Lym (6.35±2.84)%, and Treg/WBC (0.05±0.05)% in the patients with CR as the best response group were lower than those in the PR group [(29.68±5.49)%( P<0.01), (21.85±2.1)%( P<0.01), 0.50±0.69( P<0.05)] before CAR-T cell immunotherapy. Patients with lower mean Treg/CD4 +T within 1 to 15 days after reinfusion of CAR-T cells had higher peak CAR-T copy number ( P<0.05). Conclusion:Treg/CD4 +T and Treg/Lym were increased and then decreased during CAR-T treatment in B cell malignancies. The patients with lower proportions of Treg before infusion have favorable treatment efficacy. Besides, patients with lower Treg/CD4 +T after infusion have better CAR-T cell expansion. In the process of CAR-T cell immunotherapy, the use of MFC to dynamically monitor the proportion of Treg has certain clinical significance for the prediction of the optimal efficacy of immunotherapy and the prediction of treatment response.

Sulfonylureas are widely used oral anti-diabetic drugs. However, its long-term usage effects on patients' lifespan remain controversial, with no reports of influence on animal longevity. Hence, the anti-aging effects of chlorpropamide along with glimepiride, glibenclamide, and tolbutamide were studied with special emphasis on the interaction of chlorpropamide with mitochondrial ATP-sensitive K+ (mitoK-ATP) channels and mitochondrial complex II. Chlorpropamide delayed aging in Caenorhabditis elegans, human lung fibroblast MRC-5 cells and reduced doxorubicin-induced senescence in both MRC-5 cells and mice. In addition, the mitochondrial membrane potential and ATP levels were significantly increased in chlorpropamide-treated worms, which is consistent with the function of its reported targets, mitoK-ATP channels. Increased levels of mitochondrial reactive oxygen species (mtROS) were observed in chlorpropamide-treated worms. Moreover, the lifespan extension by chlorpropamide required complex II and increased mtROS levels, indicating that chlorpropamide acts on complex II directly or indirectly via mitoK-ATP to increase the production of mtROS as a pro-longevity signal. This study provides mechanistic insight into the anti-aging effects of sulfonylureas in C. elegans.
