Objective To explore neural plasticity around an injured region of the spinal cord and the effects of step training on functional recovery after incomplete spinal cord injury (SCI). Methods Adult female Sprague-Dawley rats ( n = 24) were induced with spinal cord contusion at T10 and divided into a step training group and a control group ( 12 rats in each). Training started from the 7th day post-injury and lasted for (20 ± 10)min per day, 5 days per week, for 9 weeks. Treadmill speeds were 3 m/min at the beginning, and adjusted daily according to each rat's tolerance up to 11 m/min or more. The functional recovery was measured weekly with the open-field locomotor rating scale of Basso, Beattie and Bresnahan (BBB score). The expression of glial fibrillary acidic protein (GFAP), neurofilament protein (NF) and growth-associated protein-43 (GAP-43) in the spinal cord around the injured region were detected. Results After 70 days of step training, the average BBB score of the step training group reached ( 12.86 ± 0.94 ), significantly higher than that of the control group ( 10.71 ± 0.95 ). The expression of NF and GAP-43 around the injured region increased significantly more in the step training group than among the controls. Conclusions Step training can promote functional recovery and neural plasticity in rats after incomplete SCI.

Objective To investigate the changes and prognostic significance of bone marrow(BM) oil drop and megakaryocyte counts after chemotherapy in acute myeloid leukemia (AML) patients (non-M3).Methods Ninty-nine adult patients with denovo AML (non-M3) were retrospectively analyzed to evaluate the change of BM oil drop and megakaryocyte counts and their influences on overall survival(OS) and disease free survival (DFS) during all stages of standardized therapy.Results The median DFS and OS were 21 (2-88);months and 70 (4-89) months,respectively; and 3-year predicted DFS and OS were 47.3 % and 55.8 %,respectively.After AML patients (non-M3) achieving complete remission (CR) by induction therapy,BM oil drop tended to increase along with postremission chemotherapy cycle accumulation, while megakaryocyte counts tended to decrease.The univariate analysis indicated that megakaryocyte counts decreased after the second course of postremission therapy. BM oil drop increased after the first to the third course of postremission therapy.Grade of myelofibrosis in BM biopsy,serum lactate dehydrogenase (LDH) level at diagnosis,flow cytometric immunophenotyping, the percentage of BM blast cells at diagnosis and the percentage of residual leukemic cells (RLC) during aplasia (7-10 days after the end of induction therapy) had prognostic significance.Multivariable COX analysis indicated the percentage of BM blast cells at diagnosis and change of BM oil drop after the third postremission therapy were independent prognostic factors for DFS (P =0.010,0.018 respectively),and RLCs during aplasia and change rate of the megakaryocyte counts after the second postremission therapy were independent prognostic factors for OS (P =0.009, 0.038respectively).Conclusion After AML patients (non-M3) achieving CR by induction therapy,BM oil drop tends to increase along with postremission chemotherapy cycles accumulation,while the megakaryocyte counts tend to decrease.Dynamic observations of bone marrow oil drop and megakaryocyte counts are helpful for assessing the prognosis of acute myeloid leukemia (non-M3).

To study the protective effect of astragalus saponin extracts (AS) on kidneys of diabetic rats. Totally 32 diabetic rats induced by streptozotocin (STZ) were divided into AS high and low dose groups, the positive control group and the model group (DM group) and orally administered with 50 mg x- kg(-1) x d(-1) AS 200, 25 mg x kg(-1) x d(-1) valsartan, 10 mL x kg(-1) x d(1) physiological saline, respectively. Another 8 healthy rats were collected in the normal control group (NC group, physiological saline 10 mL x kg(-1). d(-1)). All rats were treated for consecutively 6 weeks. After the administration, the body weight was measured every week, the concentration of blood glucose was monitored on week 2, 4 and 6. The total urine and total urinary protein (U-TP) in 24 h were measured by the metabolic cage method on week 6; At the end of week 6, blood samples were collected from hearts to detect blood urea nitrogen (BUN), serum creatinine (Scr), uric acid (UA) , total cholesterol (CH) triglyceride (TG) by biochemical methods. Kidneys were collect to calculate the kidney hypertrophy index and observe the pathological sections. The laboratory results show that in the DM group, the blood glucose, metabolic cost in 24 h, kidney hypertrophy index, U-TP, BUN, Scr, UA, TG were significantly higher than that in the NC group (P < 0.01, P < 0.05) , with significant pathological changes; After the intervention with AS, the metabolic value in 24 h, kidney hypertrophy index, U-TP, BUN, Scr, UA, TG were significantly lower in the high dose group (P < 0.01, P < 0.05), and the kidney hypertrophy index, BUN, Scr, UA, TG in the low dose group were also significantly lower (P < 0.05), with slight reduction in renal pathological changes in both groups. In conclusion, Astragalus saponin extracts have a certain protective effect on kidneys of diabetic rats.
