Objective To investigate the NO and NOS activities of retina tissue after hemorrhagic shock and resuscitation in rabbit and the effects of taurine on them. Methods Twenty four New Zealand rabbits were randomly divided into three groups: control group, shock and resuscitation (SR) group and taurine group. Chromatometry was used to detect the NOS activities. Results The ON content and NOS activities, either in retina tissue or in plasm, increased significantly 3 h after hemorrhagic shock and resuscitation (P

Objective: To determine the contents of thromboxane (TXA_2) and prostacyclin (PGI_2) in optic nerves after acute intraocular hypertension injury so as to provide experimental data for the treatment of the clinical intraocular hypertension. Methods: A rabbit acute intraocular hypertension injury model was established by 90-min anterior chamber douche. Thirty adult rabbits were equally randomized into 5 groups: 4 intraocular hypertension injury groups (60 min, 90 min, 24 h and 48 h after intraocular tension normalization) and a normal control group. The eyes of all rabbits were removed and the homogenate of optic nerves was used to determine the contents of TXB_2 and 6-Keto-PGF_ 1?, and the metabolites of TXA_2 and PGI_ 2 by radioimmunoassay. Results: The contents of TXB_2 and 6-Keto-PGF_ 1? in the 60 min and 90 min groups were significantly higher than those of the normal control group (P

Objective To study the effect of core stability training on motor function in patients with hemiplegia after stroke. MethodsSixty-eight patients with hemiplegia after stroke were randomly divided into a treatment group (34 cases) and a control group (34 cases).Both groups were given regular rehabilitation training.The patients in the treatment group also were taught core stability training.The trunk control test (TCT),Berg's balance scale (BBS),the modified Barthel index (MBI),functional ambulation categories (FACs) and the Fugl-Meyer assessment scale (FMA) were used to assess motor function before and after treatment. ResultsThere were significant differences between the two groups in average TCT scores,BBS scores,FACs,M BI scores and FMA scores after treatment.The gains in the treatment group were significantly superior to those in the control group.The patients'trunk control was positively correlated with the BBS,MBI,FAC and FMA results.Conclusion Core stability training can improve the motor function of patients with hemiplegia after stroke.

Objective:To explore the possible effects of Bushen Huoxue Formula (the kidney tonifying and blood activating prescription) on the proliferation and extracellular matrix synthesis of nucleus pulposus cells by regulating the circ_0036763/miR-583 axis.Methods:Real time fluorescence quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression levels of circ0036763 and miR-583 in normal and intervertebral disc degeneration (IDD) nucleus pulposus cells; IDD nucleus pulposus cells were divided into pcDNA group, pcDNA circ_0036763 group, pcDNA circ_0036763+ mimic NC group, and pcDNA circ_0036763+ miR-583 mimic group. qRT-PCR was used to detect the expression levels of circ_0036763 and miR-583 in nucleus pulposus cells in each group, methyl thiazolyl tetrazolium (MTT) was used to detect cell proliferation (A value), and Western blot was used to detect the expression of proliferating cell nuclear antigen (PCNA), collagen Ⅰ, and collagen Ⅱ proteins in nucleus pulposus cells, The dual luciferase assay reported experimental validation of the targeting relationship between circ_0036763 and miR-583. 27 mice were divided into sham surgery group, IDD group, and kidney tonifying and blood activating formula group. IDD models were established in all groups except for the sham surgery group. After successful modeling, the sham surgery group and IDD group were given physiological saline by gavage, while the kidney tonifying and blood activating formula group was given 1.5 g/ml of kidney tonifying and blood activating formula by gavage for 3 consecutive weeks. QRT-PCR was used to detect the expression levels of circ0036763 and miR-583 in the nucleus pulposus cells of mice in each group, MTT was used to detect cell proliferation, and Western blot was used to detect the expression of PCNA, collagen Ⅰ, and collagen Ⅱ proteins.Results:The expression level of circ_0036763 in IDD nucleus pulposus cells decreased, while the expression level of miR-583 increased (all P<0.05); Overexpression of circ_0036763 can promote proliferation and extracellular matrix synthesis of nucleus pulposus cells (all P<0.05); Circ_0036763 targets miR-583 and upregulates miR-583 reversible overexpression. Circ_0036763 enhances the proliferation and extracellular matrix synthesis ability of IDD nucleus pulposus cells. Compared with the sham surgery group, the IDD group showed an increase in collagen Ⅰ protein expression and miR-583 expression levels (all P<0.05), while the cell A value, PCNA and collagen Ⅱ protein expression, and circ_0036763 expression levels decreased (all P<0.05); Compared with the IDD group, the Kidney Tonifying and Blood Activating Formula group showed a decrease in collagen Ⅰ protein expression and miR-583 expression levels (all P<0.05), while the cell A value, PCNA and collagen Ⅱ protein expression, and circ_0036763 expression levels increased (all P<0.05). Conclusions:The kidney tonifying and blood activating formula (Bushen Huoxue) may induce proliferation and extracellular matrix synthesis of nucleus pulposus cells by regulating the circ_0036763/miR-583 axis.
