ObjectiveTo explore the number, incidence, structure and regional distribution of intellectual disabilities, causes of disability, and needs, etc. in Shanxi province.Methods75,016 people from 88 towns and streets of 22 cities and districts were investigated by a multi-stage sampling method in accordance with established procedures forms composed by trained investigators.ResultsThe incidence of intellectual disability was 0.34% most of which were with grade three and four in Shanxi Province. The incidence was the highest in youth in men while highest in childhood in women. The number of grades one and two of youth was more than that of other people. Incidence of intellectual disability in rural areas was significantly higher than in urban (P＜0.001). The major causes of disability were brain diseases, unknown cause, genetic, seizure disorder and other trauma. Only 43.8% of the disabled received a little services and support, including medical services and relief, poverty relief and services, rehabilitation training and services. Different people had different needs of major rehabilitation.ConclusionThe situation of intellectual disabilities was hopeful in Shanxi province. There was no discrimination of gender. Expanding groups with receiving service and support, providing targeted prevention measures according to needs of different groups and strengthening rural governance residual disability were the focus for future work.

Objective:To investigate the mechanism of endoplasmic reticulum (ER) stress-induced chemoresistance to cisplatin in gastric cancer cells. Methods:ER stress models were established in both BGC823 and SGC7901 gastric cancer cells. The expression of GRP78, an ER stress marker, was examined by Western blot analysis. Moreover, whether ER stress can decrease the sensitivity of gastric cancer cells to cisplatin and activate P38 was explored by flow cytometry and Western blot analysis, respectively. Whether ER stress-induced chemoresistance to cisplatin can be abrogated by blocking P38 activity in gastric cancer was also elucidated using flow cytometry. Results:GRP78 protein expression markedly increased after treating BGC823 and SGC7901 gastric cancer cells with tunica-mycin (TM) or thapsigargin (TG) for 8, 16, and 24 h (P<0.05), compared with that in the group treated for 0 h. The apoptotic rates of TM-(or TG)-, cisplatin-, and TM (or TG) plus cisplatin-treated groups significantly increased (P<0.05) in both BGC823 and SGC7901 gastric cancer cells compared with the rate in the control group. The apoptotic rate of TM (or TG) plus cisplatin-treated group signifi-cantly decreased (P<0.05) in both BGC823 and SGC7901 gastric cancer cells compared with that of the cisplatin-treated group. Com-pared with the group treated for 0 h, phospho-P38 expression markedly increased after treating BGC823 and SGC7901 gastric cancer cells with TM (or TG) for 8, 16, and 24 h (P<0.05). No difference in P38 protein expression was observed between each group in both BGC823 and SGC7901 gastric cancer cells (P>0.05). Both P38 inhibitors, either SB203580 or PD169316, can inhibit the activation of P38. The inhibition of P38 activity can overcome ER stress-induced chemoresistance to cisplatin in gastric cancer cells (P<0.05). Con-clusion:ER stress can trigger the chemoresistance to cisplatin by activating P38 in gastric cancer cells.

ObjectiveTo investigate the situation characteristic, cause and needs of visual disability in Shanxi Province and to provide prevention measures corresponding to different causes.MethodsBy cluster random sampling, 88 townships were selected and 75016 persons received the eye examination in 22 countries in Shanxi from July 1 to May 31 in 2006. Visual acuity and eye examination were performed by ophthalmologist and judged the causes.ResultsThe total prevalence rate of visual impairment in Shanxi was estimated to be 6.21‰.The was a significant increase in the prevalence rate of visual impairment as the age grew older(χ2＝415.54, P<0.05), those in women was higher than that in men(χ2＝40.62, P<0.05). The prevalence rate of visual impairment in countryside was significantly higher than that in city(χ2＝25.37, P<0.05).The chief causes of visual impairment were cataract(39.34%), there are 43.91% of visual impairment who had not received any rehabilitation services, and most of those were medical services (35.26%).ConclusionVisual impairment prevention should establish a social security system and security system. Increase the investment of medical services and relief. To take different preventive measures corresponding to different ages. The preventive of visual impairment of shanxi should be focus on senile eye diseases. The major work should be put in remote rural area.

Objective To assess the activity of Crohn’s disease (CD)by using the quantitative parameter of dynamic contrast-enhanced MRI (DCE-MRI).Methods 50 CD patients with ileocecal solitary lesion were recruited in this study.All of patients underwent con-ventional and DCE-MRI.The quantitative parameter of volume transfer constant (Ktrans )and the clinical data including Harvey-Brad-show index (HBI)and C-reactive protein (CRP)were recorded.(1)the reliability and repeatability of Ktrans measurement were analyzed. (2)the correlation between Ktrans value and clinical data was analyzed by using Pearson analysis.(3)according to HBI,all of the CD patients were divided into severe group,mild-moderate group,and static group.The differences of Ktrans values among the three groups were compared by using Mann-Whitney U test.Results (1)the reliability of Ktrans measurement was high (Cronbach’s Alpha=0.993).(2)there was positive correlation between HBI and Ktrans(r=0.635,P<0.001),and between CRP and Ktrans(r= 0.764,P<0.001).(3)there was significant difference of Ktrans value between the static group and the mild-moderate group (P<0.001),be-tween the static group and the severe group (P<0.001),and.between the mild-moderate group and the severe group (P<0.001). Conclusion Quantitative parameter of DCE-MRI (Ktrans )had a high reliability and can be used to assess the inflammation activity of CD.
