BACKGROUND:Mesenchymal stem cel s are the seed cel s for tendon tissue engineering which can be obtained in large quantities, but how to induce in vitro is a key technology.
OBJECTIVE:To explore the effect of platelet-rich plasma on the proliferation and col agen production of in vitro cultured mesenchymal stem cel s.
METHODS:The rabbit mesenchymal stem cel s were separated ad cultured. The high-dose platelet-rich plasma group, middle-dose platelet-rich plasma group and low-dose platelet-rich plasma group were set to induce the mesenchymal stem cel s, and the blank control group was set as control.
RESULTS AND CONCLUSION:The proliferation of mesenchymal stem cel s in the high-dose platelet-rich plasma group, middle-dose platelet-rich plasma group and low-dose platelet-rich plasma group was high, and in rapid growth with big increase amplitude, and there was no significant difference in the proliferation when compared with the blank control group (P<0.05). The effect was positively correlated with the culture time, and after cultured for a certain time, the effect was in dose-dependent manner, as higher dose platelet-rich plasma had more significant effect on the proliferation of the cel s. The results indicate that platelet-rich plasma can significantly promote the synthesis of col agen type Ⅰ and Ⅲ of mesenchymal stem cel s, the higher the dose, the more significant the effect on the col agen.

Objective To investigate the distribution of neurons expressing Fos protein in central nervous system (CNS) following esophageal mucosal acid exposure,and to map the contribution of spe- cific brain areas in sensitizing responsivity and emphasize the coding change of CNS to the esophageal acid stimulation.Methods Thirty-six healthy Sprague-Dwley rats were randomly divided into five groups. Group A (n=6) was normal group of home cage control animals to which no stimulation was given. Group B (n=7) was saline group which received esophageal perfusion with normal saline solution (0.9% NaCl).Group C (n=8) was treated with esophageal mucosal acid exposure containing 0.1 mol/L HCl. Group D (n=7) was sensitized by ovalbumin.Group E (n=8) received basal ovalbumin-sensitization plus esophageal mucosal acid exposure.The rat model of esophageal visceral hypersensitivity was estab- lished by the basic ovalbumin-sensitization combined with intra-esophageal mucosal acid exposure.The neuronal expressions of c-fos proto-oncogene were detected with immunohistochemical counter-staining and computerized color image analyzer under various conditions.Results The rats in model group with basic ovalbumin-sensitization plus esophageal acid perfusion initiated a high density expression of c-fos- immunoreactive(Fos-IR) neurons in multineuronal networks.A significantly higher number of Fos positive neurons was found in the model group than those in the corresponding regions of other groups (P＜0.05) in the following brain areas:frontal and parietal cortex,insular cortex,cingulated cortex,central amyg- daloid nucleus,the K(?)lliker-Fuse nucleus,the nucleus ambiguus,parabrachial nucleus,hypothalamic paraventricular nucleus,paraventricular thalamic nucleus,paratrigeminal nucleus,the nucleus of solitary tract,area postrema,reticular nucleus of medulla,whereas no significant difference was found in the dorsal motor nucleus of the vagus,supraoptic nucleus,periaqueductal gray matter or orbital part of infe- rior frontal gyrus.The values of Fos-IR neurons were also increased in the central amygdala,parabrachi- al nucleus,paraventricular nucleus,the paratrigeminal nucleus and NTS in the model group than that in the corresponding regions of other groups (P＜0.05).Conclusion The basic ovalbumin-sensitization fa- cilitated dramatically the c-fos expression evoked by esophageal acid perfusion,suggesting that visceral hypersensitivity induced by ovalbumin may alter cortical reactivity processing of esophageal acid stimula- tion in brain areas.

Objective To investigate the efficacy of the combination of improved intramedullary VSD drainage and contained antibiotics bone graft to treat chronic tubular bones osteomyelitis.Methods From March,2011 to December,2013,our department have total of 40 patients with chronic tubular bones osteomyelitis.Twenty cases (group A) treat with one-stage osteomyelitis debridement cortical bone slotted,contained antibiotic bone and autologous bone implants and wound repair.Twenty cases (group B) treat with improved intramedullary VSD drainage 3-5 days temporarily after osteomyelitis debridement cortical bone slotted,then contained antibiotic bone and autologous bone implants and wound repair.A retrospective comparison of two groups of an average residence time of wound drainage postoperative,bone bed bacterial culture positive rate,average healing time,the average time of hospital stay,the average bone healing time,and recurrence rate of osteomyelitis.Statistical analysis with T test was used for above independent parametric.Results The two groups were followed-up for 6-24 months,independent samples t-test was used for two groups in the wound healing time,bone healing time,the drainage tube removal time and the length of hospital stay,in group A bone bed bacteria culture positive rate was 40％,group B was 5％,group A infection relapse has 2 cases,1 case was debridement cured,1 case was amputation,and the recurrence rate of 10％.Group B without infection recurrence,and the recurrence rate of 0％ ; The healing time and hospital stay of intramedullary drainage surgery patients (18.05 ± 2.74 d and 22.65 ± 2.80 d,respectively,in group B) was significantly less than one-stage surgery patients (24.10 ± 8.20 d and 28.10 ± 9.35 d,respectively,in group A),but the bone healing time and the drainage tube removal tine of two groups.There was no significant difference (P ＞ 0.05).Conclusion Contained antibiotic bone and autologous bone implants with wound healing therapy after osteomyelitis debridement cortical bone slotted with improvement VSD intramedullary drainage to treat patient with tubular bones osteomyelitis was more effective,it worthy of clinical spread.

Aim To discuss the influence of endosome/ lysosome transport proteins SNX10 on macrophage, providing new potential targets for the treatment of variety of related immune diseases . Methods The genotype of mice was identified by PCR. The role of SNX10 in phagocytosis of bacterial components and sterilization by macrophages were assessed. The levels of TNF-α、IL-12 / 23 p40 and IL-6 were measured by q-PCR and ELISA assay. Finally, the NF-κB signaling pathway was evaluated by Western blot and immuno-fluorescence staining. Results Ex vivo experiments showed that SNX10 knockout could enhance bactericid-al ability and inhibit the expression and production of TNF-α, IL-12 / 23 p40 and IL-6 of macrophages.These effects might attribute to the inhibition of NF-κB signaling pathway activation. Conclusion SNX10 knockout could enhance bactericidal ability and inhibit the inflammatory response of macrophages, and its mechanism may be achieved through the NF-κB signa-ling pathway.
