Objectives To study the effect of ubiquitin proteasome inhibitor bortezomib on apoptosis and Caspase-3 expression in human umbilical arterial vascular smooth muscle cells. Methods Human umbilical artery vascular smooth muscle cells were cultured in vitro. Different doses of bortezomib (0, 4, 10, 40nmol/L) were used to treat cell. Cell proliferation activity were detected by using CCK8 method. Western Blot assay was used to measure the expression of Pro-caspase-3 and Cleaved-PARP protein. Morphology of cells in different groups are observed by confocal microscopy and apoptosis rate were detected by flow cytometry analysis. Results Bortezomib inhibits proliferation activity of vascular smooth muscle cells. With increasing of drug concentration and treating time, cell viability are reduced (P < 0.01). Cells treated with different concentrations bortezomib for 48 h showed increased apoptosis rate (P < 0.01), decreased pro-caspase-3 protein expression and increased cleaved-PARP protein expression (P < 0.01). Laser confocal microscope found that with the increase of drug concentration, the number of apoptotic cells showed an upward trend under per high-power vision. Conclusion The ubiquitin proteasome inhibitor bortezomib may decrease the expression of pro-caspase-3 and increase Cleaved-PARP expression in human umbilical artery vascular smooth muscle cells. Additionally , it could induce apoptosis in a dose-dependent manner.

Objective To discuss the demands of replacement care service for family caregivers of the aged in Zhengzhou City,so as to provide the reference for replacement care service of the aged.Methods A total of 145 family caregivers of the aged were collected in Zhengzhou city and were investigated with a self-designed questionnaire.Results In the 145 questionnaires,106 were valid.81 (76.4％) of them expressed needing to be replaced in the process of care,and 68 (64.1％) were willing to accept replacement care service.Order of demands of replacement service content was daily life nursing (77,72.6％),disease (66,62.3％) and psychological care (60,56.6％),etc.Influencing factors of selecting replacement care service for family caregivers included quality of service (63,59.4％),service price (38,35.8％) and professional skill (37,34.9％).The degree of demand of different ages,different careers,as well as different duration of daily care of family caregivers was statistically significant for replacement care service.Conclusions The degree of demand of family caregivers of the aged for replacement care service was higher.The government needs to establish replacement care service mechanism which is suitable for China's national conditions through policy guidance and support.

Objective To construct a home-care service package for the urban disabled elderly that satisfy their demands and improve the efficiency of service. Methods From August to October, 2014, a total of 285 disabled (mild, medium and severe) elderly from a cluster sampling were investigated with the self-designed questionnaire about home-care demands among them. An initiatory service package was drawn to meet the demands reported by 40% of them or above. The package was consulted by a group of 15 experts using Delphi method. Results The final service package included 11, 19, 20 items of care for the mild, medium and severe disabled elderly, respectively. Conclu-sion The disabled elderly home-care package in Zhengzhou has been created based on the demands among disabled elderly.

Among the single index detections,the sensitivity and negative predictive value of CA72?4 were the highest ( 61. 6%, 68. 3%) , the specificity of CA19?9 was the highest( 91. 9%) ,the positive predictive value of CEA was the highest ( 80. 4%) . The sensitivity,positive predictive value and negative predictive value of the joint detection were all higher than those in each single index detection (80. 3%,87. 3%,74. 1%). The levels of CEA,CA19?9,CA242,CA72?4, CA125 and CA50 in patients with stage III and IV were significantly higher than those in patients with stageⅠandⅡ(CEA:(32. 7±7. 1)μg/L vs. (15. 9±4. 4)μg/L;CA19?9:(127. 8±33. 7) U/ml vs. (52. 5±13. 8) U/ml;CA242:(40. 3±12. 7) U/ml vs. (23. 5±8. 6) U/ml;CA72?4:(37. 6±10. 2) U/ml vs. (13. 6±4. 1) U/ml;CA125:(128. 9±38. 4) U/ml vs. (59. 7±12. 8) U/ml;CA50:(88. 3±23. 7)μg/L vs. (41. 8±15. 6)μg/L,t=13. 04,13. 32,7. 11,14. 06,10. 99,10. 64,P<0. 05) . The levels of CEA,CA19?9,CA242,CA72?4,CA125 and CA50 in the recurrent metastasis group were significantly higher than those in the non?recurrent metastasis group ( CEA:( 37. 7 ± 8. 6 ) μg/L vs. ( 3. 8 ± 1. 7 ) μg/L;CA19?9:( 110. 5 ± 29. 4 ) U/ml vs. ( 25. 5 ± 13. 8 ) U/ml;CA242:( 33. 6 ± 10. 3 ) U/ml vs. ( 15. 5 ± 6. 6 ) U/ml;CA72?4:( 33. 1 ± 15. 3 ) U/ml vs. ( 9. 3 ± 3. 0 ) U/ml;CA125:(113. 4±31. 7) U/ml vs. (28. 7±7. 8) U/ml;CA50:(55. 4±14. 6)μg/L vs. (16. 8±9. 6)μg/L,t=29. 04,18. 31,9. 86,11. 47,19. 28,14. 65,P<0. 05) .
