Objective To evaluate the clinical efficacy of a stroke unit combined with community health services for treating stroke survivors. Methods A total of 120 stroke patients were randomly divided into a " stroke unit combined with community medicine" group ( combined group) , a stroke unit group and a general treatment group. Patients in the former 2 groups were treated in a hospital stroke unit during their hospitali-zation. The general treatment group was given conventional medical treatment. After discharge, the combined group continued to receive regular rehabilitation therapy and guidance in the form of community medical services, while the stroke unit group received follow-up only. Assessment was by means of Fugl-Meyer scores, the Barthel index and self-rating on a depression scale ( SDS). The patients were assessed at admission, on discharge and 3 months after discharge. Results There were no significant differences in average limb motor function, ability in the activities of daily living ( ADL) or depressive mood among the 3 groups on admission, but at discharge, limb motor function and ADL ability in the combined group and stroke unit groups were significantly superior to those in the general therapy group. Limb motor function and ADL ability in the combined and stroke unit groups had improved further 3 months after discharge, with more significant improvements in the combined group. No significant change in depression was observed in any group at discharge, but average depression scores in the combined and stroke unit groups improved significantly in the 3 months after discharge, and there was a statistically significant difference between the combined group and the general group. Conclusion Supplementing the work of a stroke unit with community health services significantly improves stroke patients' recovery of limb motor function and ADL ability.

OBJECTIVETo evaluate the effects of Icariin (ICA) on the proliferation and osteogenic differentiation of human periodontal ligament stem cells (hPDLSCs) in vitro and in vivo.
METHODSAn enzymatic digestion block was used in vitro to culture hPDLSCs, which were separated and purified by limited dilution cloning. The hPDLSCs were identified using cell-surface markers and cocultured with 1 x 10(-7) mol.L-1 ICA solution. The proliferation ability of these cells was determined by thiazolyl blue tetrazolium bromide (MTT) assay. After staining with alkaline phosphatase (ALP), osteogenesis was detected by enzyme-linked immunosorbent assay. Osteoblast-related genes were analyzed by reverse transcription-polymerase chain reaction. Alizarin red staining was performed to measure the level of calcium deposition. The hPDLSCs were cocultured with 1 x 10(-7) mol.L-1 ICA and nano-hydroxyapatite scaffolds in vivo before transplantation into subcutaneous tissues of nude mice. Osteogenic abilities were histochemically analyzed after 30 days of induction.
RESULTSThe hPDLSCs were affected by 1 x 10(-7) mol.L-1 ICA, and MTT assay showed that the proliferation of the groups treated with ICA in vitro was better than that of the control groups on the second day. The ALP activity of the treated hPDLSCs was significantly enhanced after cell culture for 3, 5, and 7 days. The gene expression of osteoblastic markers was also significantly enhanced after 7 days. The deposition of mineralization after incubation with 1 x 10(-7) mol.L-1 ICA increased compared with the control after cell culture for 14, 21, and 28 days. Furthermore, the bone expression of the treatment groups in vivo was significantly enhanced compared with that of the control groups.
CONCLUSIONTreatment with 1 x 10(-7) mol.L-1 ICA can significantly promote proliferation and differentiation of hPDLSCs in vitro and in vivo. ICA can effectively function as a bioactive growth factor in periodontal tissue engineering to replace traditional growth factors.
