ABSTRACT
@#The field of rehabilitation medicine physical therapist (PT) training and education has been relatively weak links in China, how to build a rehabilitation therapist team, we constantly explore and get a greater progress. However, most of the time is still confined to empty the contents of most theoretical level, and some basic steps and the specific contents are lacked. How to stabilize therapists team? How to position therapists? It deserves to pay more attentions.
ABSTRACT
Objective To investigate microRNA expression profiles of colonic cancer without lymph node metastasis and identify the specific microRNAs associated with carcinogenesis of colon.Methods Cancerous and para-cancerous tissues (5 cm from cancer tissues of the colon) confirmed without lymph node metastasis were collected from 3 patients. The microRNAs were extracted and isolated by mirVana RNA kit. Hybridizations were made by applying the microRNAs to Agilent microRNA microarray. Data analysis was done by software of Feacture Extraction. The discovered microRNAs were confirmed by real time PCR assay. Results Twelve out of 14 microRNAs associated with colonic cancer were up-regulated in colonic tissues. They were miR-106b, miR-135b,miR-18a,miR-18b,miR-196b, miR-19a, miR-224, miR-335, miR-424, miR-20a' , miR-301b and miR-374a. The rest two of miR-378 and miR 378* were down-regulated. Two up-regulated microRNAs (miR-18a and miR-135b) were detected in 3 pairs of cancerous and para-cancerous tissues. The expression level of miR-18a and miR-135b were accordant with the results of real time PCR.Conclusions microRNA.such as miR-106b,miR-135b.miR-18a.miR-18b,miR-196b,ect,were differentially expressed between cancerous and para-cancerous tissues.Many of these target genes are supposed to participate in the process of multiple tunmorgenesis.These microRNAs play an important role in the carcinogenesis of colon.
ABSTRACT
Objective To investigate the effect of cognition training on the recovery of balance after stroke. Methods forty-five hemiplegic strokd patents with cognition deficit were revruited and sddigned into an experimental group and a control group according to the results of an assessment with Loewenstein's Occupational Therapy Cognition Assessment battery (LOTCA). The patients in the two groups folloled routine systmatic rehabilitation programs. The patients in the (LOTCA). The patients in the two groups followed routine systmatic rehabilitation programs.The patiena in the experimental group received pertinent cognition training 5 days/week for 6 weeks. LOTCA,Brunel's Balance Assessment (BBA), the Berg Balance Scale (BBS) and Brunnatrom functional categories were enployed to evaluate the patients before and after treatment with regard to their cognition, balance control and motor function in their lower limbs. Results After treatment, there were statistically significant differences between preand post-treatment BBA and BBS scores in all groups. Average BBA, BBS and LOTCA scores in the experimental group were significantly higher than in the control group. The improvements in BBS, BBA and LOTCA scores in the experimental grou were significantly greater than in control group. Conclusion Cognition treatment can contribute significantly to improving balance and postural control among stroke survivors.
ABSTRACT
Objective To study the expression and clinical significance of?-catenin and c-myc in gastric adenocarcinoma and corresponding para cancer gastric mueosa.Methods Two hundreds and ninety seven samples were collected from 102 cases of gastric adenocarcinoma,including 102 cancerous tissues and 195 para-cancerous tissues.Each sample was made into 282,156 and 156 dots tissue microarrays.Expressions of?-catenin and c-myc proteins were detected by immunohistochemical stain- ing.Results The expressions of?-catenin and c-mye were increased gradually in the process of gastric carcinogenesis.The rates of?-catenin and c myc expression were higher in carcinoma than that in intesti- nal metaplasia( P＜0.05,P＜0.001).The aberrant expression of?-catenin was closely related to the depth of invasion(P＜0.05),and the expression of c-myc was related to histological grade( P＜0.05). The aberrant expression of?-catenin was significantly correlated with the expression of c-myc in gastric adenocarcinoma(P＜0.05).Conclusions The aberrant expression of?-catenin may activate the expres sion of target gene c-myc,which plays a pivotal role in the carcinogenesis and progression of gastric adenocarcinoma.
