Objective To investigate the expression of survivin in T lymphocytes that were stimulated by Con A and alloantigens in renal grafts in vitro and in vivo. Methods According to the different treatments, the experiment was divided into three parts. (1) The C57BL/6 mice splenocytes stimulated by Con A (10 mg/L) were cultured in the RPMI-1640 medium. Following the proliferation blockade or not, the expression of Survivin in the splenocytes was detected. (2) The GVHR model was established by transfusing the C57BL/6 mice splenocytes into Balb/c× C57BL/6 F1 mice, and the expression of Survivin in the donor splenocytes was detected at the different time points. (3) Seventythree cases of clinical renal allograft biopsy specimens were collected, pathologically diagnosed and classified according to the Banff 97 classification, and then the expression of Survivin was detected.Results Survivin was expressed in the CD3+ splenocytes that received Con A stimulation. The positive cell count reached the peak on the day 3, and subsequently declined. In the GVHR model, the lymphocytes infiltration and Survivin expression were detected around the portal vein and portal area on the post-splenocytes-transfused day (PSTD) 4 to 12. But on the PSTD 14, the Survivin expression could not be detected in the infiltrated lymphocytes. In the renal allograft biopsy specimens,lymphocytes did not express Survivin in 13 specimens of the group without acute cellular rejection.was difference between the two groups (P<0. 01 ). Conclusion The activated T cells possess the capacity to express Survivin, and the expression is time-dependent. For the characteristics of Survivin expression of T cells, it may be applied as an approach to diagnose the acute cellular rejection and judge its degree and stage in the clinical allograft biopsy specimens.

Anemarrhena asphodeloides processed by salt and raw product was compared including both chemical composition and laxative function in order to find the possible active substance to cure constipation. Processed and raw Anemarrhenae laxative effect on experimental constipation models was observed as well as chemical composition using UPLC-MS technology and the total sugar content was determined by phenol sulfuric acid method. Processed Anemarrhenae water extract improved excrement more than raw which has significant difference compared with the blank group (P < 0.05). On the other hand, the total ion flow spectrum showed no significant difference in most substance, but the total sugar content was significantly higher than raw product. Anemarrhenae ancient be recognized benefitting for draining body water in traditional Chinese medicine which has been lost in modern books because it is manifested as excellent laxative effect not diuretic effect. Saccharides carbohydrate may have closely relationship with this magically effect.

Objective: To observe the clinical efficacy of acupuncture plus MOTOmed intelligent motor training in treating children with spastic cerebral palsy, and analyze the effects on lower limb motor function, intelligence development level, immune function and cerebral hemodynamics.Methods: A total of 42 children with spastic cerebral palsy were selected as the observation objects, and enrolled into the observation group. Another 42 cases treated in the same period were selected as the control group. Both groups received MOTOmed intelligent motor training, and the observation group was given additional acupuncture therapy, and the control group was given additional conventional rehabilitation treatment. After 2 consecutive treatment courses, the psychomotor development index (PDI) and mental development index (MDI) of Children's Developmental Center of China (CDCC) scale, the scores of gross motor function measure (GMFM) scale and modified Ashworth scale (MAS), and the changes in CD3+, CD4+, CD8+ and CD4+/CD8+ were observed. The peak systolic velocity (PSV) and mean flow velocity (MFV) of the anterior cerebral artery (ACA), middle cerebral artery (MCA) and posterior cerebral artery (PCA) were observed and measured. The clinical efficacy was evaluated. Results: Compared with the same group before treatment, the scores of GMFM, PDI and MDI, levels of CD3+, CD4+ and CD4+/CD8+, PSV and MFV levels of ACA, MCA and PCA in both groups were significantly increased after treatment (all P<0.05), while the CD8+ level had no significant change (both P>0.05). After treatment, the total effective rate of lower limb spasm in the observation group was 90.5%, significantly higher than 71.4% in the control group (P<0.05). The scores of GMFM, PDI and MDI, the levels of CD3+ and CD4+, PSV and MFV, and the levels of ACA, MCA and PCA in the observation group were all significantly higher than those in the control group (all P<0.05). There were no significant differences in the CD8+ level and CD4+/CD8+ between the groups (all P>0.05). Conclusion: Acupuncture plus MOTOmed intelligent motor training has a better clinical efficacy than conventional rehabilitation plus MOTOmed intelligent motor training in treating children with spastic cerebral palsy, and is also superior in improving lower limb motor function and the level of intellectual development. And the mechanism may be related to the improvement of cerebral hemodynamics.
