Objective To explore influence of norm-setting three-stage rehabilitation training on hemiplegic stroke patients with movement and cognitive dysfunction. Methods A prospective randomized controlled study and stepwise linear regression analysis was carried out to investigate the early variation factors, which affected the integrated functional recovery of stroke patients. According to variation factors we established our norm-setting three-stage rehabilitation training program. 200 patients were randomly selected, according to the cerebral infarction and cerebral hemorrhage classification, and then randomly divided into the rehabilitation group and the control group with 100 patients in each group. All patients accepted general neurology routine nursing. The rehabilitation group was given an extra norm-setting three-stage rehabilitation training. The improvement of motor and cognitive function were observed. Results The early variation factors of integrated functional outcome were treatment programs, CNFD score, age, diabetes, SFMA score, smoking and the intensity of labor within six months since stroke onset. Movement and cognitive function of the rehabilitation group significantly improved than the control group as well as upon admission on the first, 3rd and 6th months since stroke onset. Conclusions The norm-setting three-stage rehabilitation training obviously promotes the improvement of motor and cognitive function at all stages.

Objective To investigate the diagnosis and treatment of idiopathic chronic colonic pseudo-obstruction(ICCPO). MethodsIn this study 69 patients admitted for “constipation” were finally found falling into one of the 4 groups: 11 cases of outlet obstructive constipation, 16 cases of slow transit constipation, 26 cases of mixed type, and 16 of ICCPO. ResultsThe main symptoms of these 16 ICCPO cases were intractable constipation, compared with that in other entities ICCPO tends to affect patients at younger age, with shorter clinical course, and often needs surgical intervention due to intractable bowel obstruction, usually total colectomy. ConclusionsICCPO, STC and mixed constipation are different clinical entities. The differentiation of ICCPO from other entities is sometimes very difficult especially when patients are suffering from acute onset of bowel obstruction.

OBJECTIVEWe explored the expressions of the Notch and Wnt signaling pathways and their significance in the repair process of alveolar bone defects by establishing animal models with a composite of autologous bone marrow mesenchymal stem cells (BMSCs) and platelet-rich fibrin (PRF) to repair bone defects in the extraction sockets of rabbits.
METHODSA total of 36 two-month-old male New Zealand white rabbits were randomly divided into four groups, and the left mandibular incisors of all the rabbits were subjected to minimally invasive removalunder general anesthesia. BMSC-PRF compounds, single PRF, and single BMSC were implanted in Groups A, B, and C. No material was implanted in Group D (blank control). The animals were sacrificed at 4, 8 and 12 weeks after surgery, the bone defect was immediately drawn, and the bone specimens underwent surgery after four, eight, and twelve weeks, with three rabbits per time point. The expressions of Notch1 and Wnt3a in the repair process of the bone defect were measured via immunohistochemical and immunofluorescence detection.
RESULTSImmunohistochemistry showed that the expressions of Notch1 and Wnt3a in Groups A, B, and C were higher than that in Group D at the fourth and eighth week after operation (P<0.05). By contrast, the expressions of Notch1 and Wnt3a in Group D were higher than those in Groups A, B, and C at the twelfth week (P<0.05). Immunofluorescence showed that the expressions of both Notch1 and Wnt3a reached their peaks in the new bone cells of the bone defect after four weeks following surgery and gradually disappeared when the bone was repaired completely.
CONCLUSIONNotch1 and Wnt3a signaling molecules are expressed in the process of repairing bone defects using BMSC-PRF composites and can accelerate the healing by regulating the proliferation and differentiation of BMSCs. Moreover, the expressions of Notch and Wnt are similar, and a crosstalk between them may exist it.
