AIM: To investigate whether viable apoptotic cells and phagocytosis of them affect the activation of T lymphocytes. METHODS: Ultraviolet irradiation was used to induce apoptotic cells in vitro and the model of phagocytosis of these cells was established. Cytokine TGF ?1 was detected by ELISA. The rate of apoptotic cells and phagocytosis of them were assessed by flow cytometry. Furthermore, flow cytometry was also employed to examine the expression of activation signs, such as CD69, CD25, CD71, of T lymphocytes under the intervention of apoptotic cells and macrophage which ingested apoptotic cells, to reflect whether the apoptotic cells and the phagocytosis of these cells could influence the activation of lymphocytes stimulated by Con A. RESULTS: Ingestion of apoptotic cells increased TGF ?1 secretion. Only the macrophages that had ingested apoptotic cells could suppress the activation of lymphocytes. The expression of the markers of lymphocytes activation such as CD69, CD25, CD71 had been restrained. These inhibition effects were abolished by monoclonal anti-TGF ?1 antibody. CONCLUSION: The macrophages that have ingested apoptotic cells inhibit expression of CD69, CD25 and CD71 of T lymphocytes stimulated by ConA. This effect is dependent on the increase in TGF ?1 secretion in local site. [

BACKGROUND: Posterior transarticular screw fixation (Magerl’s) is recommended for atlantoaxial instability. However,some patients do not suit for Magerl’s fixation. OBJECTIVE: To evaluate the clinical outcomes of atlantoaxial pedicle screw system in the treatment of atlantoaxial instability from odontoid fracture. DESIGN,TIME AND SETTING: The retrospective case analysis was performed at the Department of Orthopedics,Sichuan People’s Hospital between July 2004 and June 2007. PARTICIPANTS: Twenty-one cases of atlantoaxial instability from odontoid fracture were selected. According to Anderson and D’Alonzo classification,9 of them belonged to type II odontoid fracture with atlantoaxial instability and 12 to type Ⅲ with severe atlantoaxial dislocation. All cases suffered pain at occipitocervical part and limited activities of cervical spine. According to Frankel classification in function of spinal cord,16 cases of them belonged to Grade E and 5 cases to D. METHODS: All cases were fixed with C1 and C2 pedicle screws system following skull traction and reduction. MAIN OUTCOME MEASURES: Biocompatibility between materials and host; bone graft fusion and functional improvement. RESULTS: No vertebral artery injury or spinal injury was found during operation,neither incision infection was. All cases were followed up for at least 8 months. Postoperative radiograph and CT detection revealed good positions of all screws with no loosening or breakage. All fractures healed within 5 months,and activities of cervical vertebra were not obviously limited except slightly limited rotation function. As for nerve function,5 cases of Grade D recovered up to Grade E. CONCLUSION: Posterior pedicle screw fixation system exhibits no specific biocompatibility responses. It greatly improves atlantoaxial stability and promotes functional recovery of spinal cord but has little influence on cervical function.

Objective To explore the speech respiratory characteristics of 7-15 years old children with spastic cerebral palsy and the differences between ordinary children and children with cerebral palsy.Methods The maximum phonation time (MPT) and maximum counting ability (MCA) of 90 ordinary children and 58 children with cerebral palsy aged 7-15 years were measured and a comparison between the 2 groups were conducted.Results (1) Age has significant effects on MPT and MCA of the ordinary children (P <0.05).The MPT and MCA of the ordinary children at the age of 7 ~9 years and 10 ~ 12 years are lower than the ones at the age of 13 ~ 15 years.Age has almost no effects on MPT and MCA of children with cerebral palsy(P >0.05) ; (2)Sex has no significant effects on MPT and MCA of ordinary children and children with cerebral palsy (P >0.05) ; (3) The MPT and MCA of children with cerebral palsy are significantly lower than those of ordinary children (P <0.05).Conclusions The MPT and MCA of ordinary children are increased with the growth of age,especially after the age of 13 years,but the children with spastic cerebral palsy do not show that kind of trend and demonstrate a state of retardation of speech respiratory function.Compared with ordinary children,the children with spastic cerebral palsy are easier to suffer from insufficient respiratory support and poor respiratory-phonatory coordination.

At present, there are many effective ways to achieve high performance in cluster system storage management, including server-end disk, server-end caching, local caching and cooperative caching. The cooperative caching mechanism shares caches among different clients so as to avoid expensive disk access costs and to improve overall throughput of cluster system. In this paper, a Single Copy Cooperative Cache model is proposed together with block lookup algorithm, block replacement algorithm and the consistency algorithm based on the model. Meanwhile, the prototype system of the model is implemented in PVFS file system. Finally, the performance of this system is tested in InfiniBand Framework, the result of which shows that in contrast to the original PVFS system, read performance of PVFS file system is improved by about two times, while write performance is reduced by nearly ten percent.

Objective To study preparation of micronized Shuanghuangpo hydrogel patch and its characteristics of transdermal penetration in vitro. Methods Micronized Shuanghuangpo hydrogel patch was prepared with some macromolecular water-soluble materials as gel base.The content of berberine was determined by HPLC method.Its transdermal penetration in vitro was determined according to the method of Chinese Pharmacopoeia 2010 edition. The rat skin penetration test in vitro was performed by modified Franz diffusion cell method. Results The hydrogel patch had constant content of berberine. Its release property in vitro conformed to Higuchi equation. The penetration of berberine in the hydrogel patch through the rat skin followed zero-order dynamics in 12 h.Its release rate was 7.934μg??(cm2)-1??h1/2 and percutaneous rate was 0.571μg??(cm2)-1??h-1. Conclusion The micronized Shuanghuangpo hydrogel patch is a new transdermal agent with sustained release property.
