Objective To explore the effect of early phase rehabilitation training on the urination function recovery of the patients with paraplegia caused by spinal cord injury (SCI).Methods Sixty-six patients with paraplegia caused by SCI were selected and divided into the rehabilitation and the control group.The rehabilitation group of patients received early phase rehabilitation training on the urination function,the control group received routine training on the urination training and urinary catheter nursing care.The urination function recovery effect was compared between two groups.Results The urination function recovery effect of the rehabilitation group was significantly better than the control group.Conclusions The usage of early phases of urination training measures on the SCI paraplegia patients can help them cast off the catheter,build up regular urination,and reduce complications.

Objective To investigate the effect of human bone marrow mesenchymal stem cells (BM-MSCs) stimulated by platelets in vitro on the metastasis of cancer cells.Methods The BM-MSCs were isolated and cultured in vitro and platelets from the peripheral blood of healthy persons were purified.The MSCs (control),platelets + MSCs,and platelets treated with culture media (CM) of SGC-7901 tumor cells + MSCs (T-platelets + MSCs) were cultured,respectively,and the MSCs and supernatants (MSCs-CM and SGC-7901-CM) were collected,respectively,after 24 hours.The expressions of markers of cancer-associated fibroblasts (CAF),such as α-SMA and Vimentin,were determined by Western-blotting.The immigration ability of BM-MSCs were analyzed by Transwell assay.The levels of P-selectin in platelets stimulated by MSCs-CM or SGC-7901-CM were detected with flow cytometry.The metastasis model of gastric cancer SGC-7901 cells was established in BALB/c nude mice by the injection of tail vein,and the tumor metastasis in vivo was observed.Results The expression levels of P-selectin in platelets stimulated by MSCs-CM ([21.37 ± 1.00] ％) or SGC-7901-CM ([31.4 ± 1.71] ％ were significantly higher than that in the control ([3.17 ± 0.40] ％,t =27.85 and 29.18,P ＜ 0.01).The expression levels of α-SMA and Vimentin in platelets + MSCs group (0.79 ± 0.08 and 0.88 ± 0.01) and T-platelets + MSCs group (0.90 ±0.06 and 0.96 ±0.04) were significantly higher than that in the control (0.64 ±0.02 and 0.75 ±0.05,t =2.96 and 6.45 forα-SMA,t =4.73 and 5.73 for Vimentin,P ＜0.01).The amounts of immigration cells in platelets + MSCs group (340.3 ±27.7) and T-platelets ± MSCs group (424.3 ± 17.6) were significantly higher than that in the control (220.7 ± 19.4,t =6.14 and 13.48,P ＜ 0.01).The in vivo experimental results showed that the metastatic foci in platelets ± MSCs group (4 ± 2) and T-platelets ± MSCs group (21 ± 4) were significantly higher than that in the control (0.33 ± 0.06,t =3.051 and 8.857,P ＜ 0.01).Conclusion Platelets promote the immigration and the enhanced tumor metastasis in vivo of BM-MSCs.
