Chinese Journal of Rehabilitation Theory and Practice 2013;19(2):158-160
Objective To explore the effect of standardized comprehensive rehabilitation treatment on activities of daily living (ADL) of stroke patients. Methods 60 stroke patients were divided randomly into rehabilitation group (n=30) and control group (n=30). Both groups received routine internal medicine treatment, and the rehabilitation group received standardized comprehensive rehabilitation treatment additionally.ADL was assessed with BI at admission and 1, 2, 3 months after admission. Results In the control group, the score of BI was significantly higher 1 month after admission than at admission (P=0.000), and there was no difference 2 and 3 months after admission from 1 month after admission (P>0.05). In the rehabilitation group, the score of BI was significantly higher 1, 2 and 3 months after admission than at admission (P=0.000). There was no difference in the score of BI between 2 groups at admission (P>0.05), and the score of BI was significantly higher in the rehabilitation group than in the control group at other treatment periods (P=0.000). Conclusion Standardized comprehensive rehabilitation treatment could promote the ADL of stroke patients who have the trend of self-recovery at the early stage.

Objective To clarify the mechanism of immediate early response gene 5 (ler5)transcription induced by radiation. Methods Deletant construction, site-specific mutagenesis,electrophoretic mobility shift assay (EMSA) and chromatin immunoprecipitation (ChIP) were used to forecast the promoter region,binding sites and transcription factors of Ier5 gene in HeLa cells.Results The promoter region of Ier5 gene might be in the region of Ier5 -8 deletant ( -408 - -238 bp).The Ier5 gene had two transcription factors of GCF and NFI,and GCF had two binding sites located in the region of - 388 - - 382 bp and - 274 - - 270 bp of Ier5 promoter.The binding site of NFI was located in - 362 --357 bp of Ier5 promoter. GCF could inhibit the expression of Ier5 gene and this inhibition was diminished when the radiation dose increased. In contrast, NFI increased the expression of Ier5.Conclusions The most possible region of Ier5 promoter is from -408 to - 238 bp which has two binding sites for the radiosensitivity transcription factors of GCF and NFI that could negatively and positively regulate the expression of Ier5 respectively.

Objective:To explore how an enriched environment promotes synaptic remodeling in the hippocampus after cerebral ischemia.Methods:Among 60 clean, adult, male C57BL/6 mice, 16 were randomly selected into a sham operation group, while the remaining 44 underwent permanent left middle cerebral artery embolization. The 32 mice with successful modeling were randomly divided into a normal environment group and an enriched environment group, each of 16. The enriched environment group lived in an enriched environment for 28 days, while the other two groups were raised in normal conditions. The number of synapses in the CA3 area of the hippocampus was then measured using transmission electron microscopy, and the expression of Wnt7a, Dvl1, β-catenin, synaptophysin (SYN) and PSD-95 in the hippocampus were measured using western blotting.Results:Compared with the normal environment group, the average protein expression levels of Wnt7a, Dvl1, β-catenin, SYN and PSD-95 were all significantly higher in the enriched environment group. The number of synapses in the CA3 region of the enriched environment group was also significantly higher than in the normal environment group.Conclusion:An enriched environment can activate the Wnt7a-β-catenin-Dvl1 signaling pathway in the hippocampus after cerebral ischemia to promote synaptic remodeling, at least in mice.

Objective:To analyze the predictive factors of GGU between biopsy and radical prostatectomy pathology based on 2014 ISUP grouping system, then establish and evaluate nomogram.Methods:Patients undergoing radical prostatectomy in Shanghai Ruijin Hospital from March 2012 to March 2019 were reviewed, and the clinical and pathological information were collected. Age(68.1±7.2), body mass indes(BMI) (24.2±3.2)kg/m 2, prostate specific antigen(PSA) 11.5(6.7-20.4)ng/ml, prostate specific antigen destiny(PSAD) 0.35(0.20-0.66). Before March 2017, the number of biopsy cores were 6 to 8; After then, all patients toke 12 cores systemic biopsy. Based on 2014 ISUP grouping system, the differences between biopsy and radical prostatectomy grades were counted. The independent predictors of GGU were analyzed by univariate and multivariate logistic regression analysis, then the nomogram for predicting GGU were established and evaluated. Results:429 patients were enrolled. There were 161 (37.5%) patients in GGU group and 268 (62.5%) patients in non-GGU group. After multivariate logistic regression analysis, body mass index (BMI)>28 kg/m 2( OR=2.54, P=0.021), prostate specific antigen density (PSAD)( OR=1.65, P=0.018)and 2014 ISUP grouping sysyem ( OR=0.53, P<0.001) of biopsy specimen were independent impact factors of GGU. The predicting model was established according to BMI, PSAD and 2014 ISUP grouping system. The area under the ROC cure of the model was 0.735 (95% CI 0.681-0.789). The nomogram model was well calibrated, with the mean absolute error of 6.7%, which means the prediction of GGU is fairly consistent with the actual situation. Conclusions:Based on the 2014 ISUP grouping system, BMI>28 kg/m 2, PSAD and 2014 ISUP grouping of biopsy specimen were independent predictors of GGU. The nomogram model for predicting GGU has a good statistical significance.

Objective:To survey the awareness status of risk factors for gastric cancer and related factors among residents in Shijiazhuang city.Methods:From October to November 2020, residents aged>18 years were selected through convenience sampling from Xinhua District and Yuhua District in Shijiazhuang for a face-to-face questionnaire survey. The demographic characteristics and awareness levels of risk factors for gastric cancer among 1 490 subjects were analyzed. The multivariate linear regression model was applied to analyze the related factors.Results:There were 522 male participants (35.0%) and 968 female participants (65.0%). The mean knowledge score of risk factors of gastric carcinoma in the respondents was 5.0 (1.0, 11.0). There were 57.0% (849/1 490) of the participants who had a low knowledge level about risk factors of gastric cancer. The more highly recognized risk factors were irregular diet (47.4%, 706/1 490), consumption of pickled foods (45.2%, 674/1 490), consumption of smoked foods (45.0%, 671/1 490); the less-recognized risk factors included physical inactivity (14.8%, 221/1 490), male sex (17.3%, 258/1 490) and older age (19.5%, 291/1 490). Only 26.8% (400/1490) of the participants regarded H. pylori infection as a risk factor of gastric cancer. Univariate analysis showed that educational level ( Z=39.34), marital status ( Z=53.31), monthly income ( Z=11.82), family member or friend ever having stomach problem ( H=-2.98), and family history of gastric cancer ( H=-2.34) were significantly associated with the knowledge score of risk factors for gastric cancer ( P<0.05). Multivariate analysis showed that compared to participants with educational levels of primary school or below, those with educational level of junior high school ( β=0.27, P<0.001), high school ( β=0.23, P<0.001), or college ( β=0.16, P<0.001) had a higher levels of knowledge of risk factors for gastric cancer; compared to unmarried participants, awareness of risk factors was significantly better in those who were married ( β=0.16, P<0.001), divorced ( β=0.05, P=0.039), or widowed ( β=0.06, P=0.027); compared to participants with monthly income<3 000 yuan, the subjects with monthly income from 5 000 to 10 000 yuan ( β=0.07, P=0.020) had a higher knowledge score; compared to participants with no family history of gastric cancer, subjects with family history had higher knowledge level of risk factors for gastric cancer ( β=0.06, P=0.029). Conclusion:The knowledge levels of risk factors for gastric cancer are generally low among residents in Shijiazhuang city. Educational initiatives are required to improve the awareness of risk factors for gastric cancer, and interventions need to be implemented concurrently to change unhealthy behaviors among residents in Shijiazhuang city.
