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.

Objective To explore the prognostic impact of miR137 target gene Kruppel-like transcription factor 12 (KLF12) in multiple myeloma (MM). Methods The target genes of miR137 were predicted by software. The GFP analysis of KLF12 and the prognosis of MM were constructed. Overexpressing miR137 in MM NCI-H929 cell line was also constructed. Real-time qPCR and Western blot were used to detect the expression of KLF12 in this cell line. Results The target genes of miR137 were MITF, BUE2H, SH3BP5 and KLF12. High expression of KLF12 in 455 patients included 75 patients (16.5 %) died, 104 patients with low expression of KLF12, and 25 patients (24.0 %) died, but no significance was detected in the different subgroups. KLF12 expression was higher in MM NCI-H929 cell line with miR137 over expression. The expression of miR137 was positively correlated with the expression of KLF12. Conclusion miR137-KLF12 is an important index to judge the prognosis of MM.
