BACKGROUND: There are various kinds of design methods about preoperative osteotomy of ankylosing spondylitis with kyphosis, but each has their own errors and limitations. A convenient, precise and available method needs to bedeveloped.OBJECTIVE: To compare the clinical efficacy of two different preoperative osteotomy designs using paper-cut andphotoshop software for ankylosing spondylitis with kyphosis.METHODS: Thirty-nine patients suffering ankylosing spondylitis with kyphosis undergoing osteotomy in the Departmentof Spinal Surgery, Affiliated Hospital of Yan'an University between June 2009 and January 2015 were enrolled, andrandomly allotted to paper-cut (n=19) and photoshop (n=20) groups, followed by the preoperative osteotomy design,respectively. All patients were followed for 12-40 months to compare the postoperative osteotomy angle error andcorrection efficacy at the last follow-up between groups.RESULTS AND CONCLUSION: (1) The postoperative osteotomy angle error in the photoshop group was significantly smaller than that in the paper-cut group (P < 0.05). (2) At the last follow-up, the key parameters of sagittal spine and pelvis (sagittal vertical axis, Cobb angle and pelvic tilt) showed significant differences between groups (P < 0.05). (3) The Oswestry disability index and Scoliosis Research Society-22 questionnaire scores in the photoshop group weresignificantly superior to those in the paper-cut group at the last follow-up (P < 0.05), while the visual analog scale scoresdid not differ significantly between groups (P > 0.05). (4) To conclude, compared with the osteotomy design usingtraditional paper-cut splice, the photoshop software can achieve a smaller osteotomy angle error and better postoperative balance of spinal sagittal plane, thus providing precise osteotomy for surgeons to obtain proper correction.

BACKGROUND: Recent studies have shown that Taohong Siwu Decoction can alleviate the damage of vascular endothelial cells and maintain their normal secretory function, and endothelial progenitor cells can promote the repair of endothelial injury. Therefore, it is assumed that Taohong Siwu Decoction may protect endothelial function by improving the functional activity and increasing the number of endothelial progenitor cells. OBJECTIVE: To investigate whether Taohong Siwu Decoction can augment the number and functional activity of peripheral blood endothelial progenitor cells. METHODS: Endothelial progenitor cells were isolated from the peripheral blood of healthy subjects, and divided into control, low-, moderateand high-concentration Taohong Siwu Decoction groups. Cells were then cultured to observe the dose-effect relationship within 24 hours. Meanwhile, the high-concentration Taohong Siwu Decoction group was cultured for respective time points (6, 12, 24 and 48 hours) for observing the time-effect relationship. The number of endothelial progenitor cells was counted under inverted phase contrast microscope. Proliferation, adhesion and migration of endothelial progenitor cells were detected by MTT chromatometry, adhesion activity assay and modified Boyden chamber assay, respectively. RESULTS AND CONCLUSION: (1) The proliferation, adhesion and migration abilities of endothelial progenitor cells in the Taohong Siwu Decoction groups were significantly higher than those in the control group and showed a certain dose-effect relationship. (2) The proliferation, adhesion and migration abilities of endothelial progenitor cells in the Taohong Siwu Decoction groups were enhanced in a time-dependent manner, especially at 24 hours after intervention (P < 0.01). To conclude, the Taohong Siwu Decoction can increase the number of endothelial progenitor cells and promote cell functions. High-concentration Taohong Siwu Decoction exhibits the best interventional effect at 24 hours after intervention.

This paper introduced the present situation and the existing problems of palliative care and hospice care system in Russia.The coverage of palliative is narrow,regional development is not balanced,the medical professionals in palliative care is lack,the professional skills should be improved urgently,the training system of palliative care is not perfect and the quality of training is not high,the medical professionals have high work pressure,the brain drain is serious,the social cognition is not enough,the volunteer service system is underdeveloped,and the acquisition rate of mental and narcotic drugs is low.On the basis of the above,this paper introduced the development strategy of Russian palliative care,and discussed the enlightenment to our country.For example,government departments should attach importance to the introduction of legal norms of palliative care,perfect the service system of palliative care,establish the supporting facilities,reasonably plan palliative care system,implement the integration of service management and scientific research,and bring the guarantee palliative care fund into the national budget.
