Objective To study the effect of trans-theoretical model of behavior on ambulation training in stroke hemiplegic patients. Methods Sixty hospitalized stroke hemiplegic patients from June to December 2013 were selected as control group. The control group was treated with routine nursing and ambulation training guidance. Sixty-two hospitalized stroke hemiplegia patients, from January 2014 to June 2014, were selected as intervention group. Patients in the intervention group received trans-theoretical model of behavior together with ambulation training guidance for 3 weeks and follow-up record for 6 months. Holden functional ambulation categories ( FAC ) and Bathel index were used to evaluate the effect of ambulation training . Result Trans-theoretical model of behavior training improved the walking function and activities of daily living in intervention group patients , compared with those of the control group. Conclusions Taking trans-theoretical model of behavior in walking training health education can improve the ambulation ability and ability of daily living of stroke hemiplegic patients. Therefore this theory can enhance the stroke hemiplegic patients′life quality.

Objective To study the effect of the neck rotation and lateral bending on the vertebral artery blood flow, and to analyze the relationship between the artery blood flow and cervical vertigo. Methods Thirty patients with cervical vertigo were studied with exclusion of auditory vertigo and severe cardio-cerebrovascular disease, which involved 18 males and 12 females, whose average age was 52.13 years with a range of 42-73 years. They all had cervical degenerative change in different degree and neck-shoulder-back pain history. The study also included 15 volunteers without vertigo, 8 males and 7 females, the average age was 49.47 years with range, 38-70 years, they also had some cervical degenerative change. They were selected to detect the blood flow of bilateral intracranial segments of the vertebral arteries using TCD with the neck in neutral, bilateral rotation 15?,30?,45?,60? and bilateral bending. Results In neutral position, vertebral artery blood flow was lower in study group than in control(P

Purpose To investigate the expression of insulin-like growth factorIImRNA binding protein 3 ( IMP3 ) and microvessel density (MVD) in squamous carcinoma of the cervix (SCC) and analysis their relationship in SCC. Methods The expression of IMP3 and MVD was examined by immunohistochemistry SP method in normal cervical epithelium ( NCE) , low-grade cervical intraepi-thelial neoplasia (CIN-L), high-grade cervical intraepithelial neoplasia (CIN-H) and SCC. Results (1)The positive expression rates of IMP3 in NCE, CIN-L, CIN-H, SCC tissues were 0(0/15), 0(0/11), 37.5%(9/24) and 86.0%(43/50), the difference was statistically significant (x 2 =53.345, P=0.000). IMP3 expression was significant difference among NCE and CIN-H, SCC (P<0.008 3), and that was also among SCC and CIN-L, CIN-H (P<0.008 3). (2)The MVD count was increased with the development of cervical squamous lesion, there was significant difference among those groups (F=145.968, P<0.01), and the difference was al-so statistically significant between every two groups (P<0.05). The positive expression of IMP3 and MVD count in 50 cases of SCC tissues showed statistical difference in different pathologic grade, lymph node metastasis, and depth of tumor invasion groups ( P<0.05), but didn't in different patients’age groups (P>0.05). And the positive expression of IMP3 was closely related with MVD count in SCC tissues (rs =0.323, P<0.05). Conclusion IMP3 plays an important role in the occurrence, infiltration and metasta-sis of SCC, and the abnormal expression of IMP3 may relate with the angiogenesis of tumors.

In this article we report the results on the synthesis and accumulation of PHAs by Rhodocista pekingensis (strain 3-p), a phototroph that was isolated from wastewater treatment plant. Our results showed that the optimal conditions for PHAs accumulation with strain 3-p were as following: 0.01% Yeast Extract, 0.01% NH 4Cl, Acetate 5 g/L, and medium pH of 7.0～7.2.Under optimized conditions, strain 3-p accumulated PHAs up to 60% of its cellular dry weight. Enzymatic activities of ?-ketothiolase, acetoacetyl-CoA reductase, and PHA polymerase were detected and their activities increased as PHA synthesis initialized. Based on these study, we proposed the metabolic pathway of this strain should be:Acetate (or other fatty acids) - Acetyl-CoA --- thiolase Acetoacetyl-CoA --- reductase D (-)-?-Hydroxybutyryl-CoA ----- PHA polymerase PHAs.
