Objective: To determine the anti rejection effects of CTLA 4 Ig fusion protein on cardiac allografts in mice and to discuss its mechanism in vivo . Methods: BALB/c recipients were performed cervical heterotopic heart transplantation to receive C57BL/6 donor hearts with a cuff technique. BALB/c recipients were intraperitoneally injected with CTLA 4 Ig [100 ?g/d?15 times], control immunoglobins and PBS to observe the survival time of allografts with ECG. The hyporesponsiveness of splenic T cell, the polarization of the T subsets were analyzed after the recipients treated with CTLA 4 Ig. Results: After treated with CTLA 4 Ig, the survival of cardiac grafts was significantly prolonged compared with the control groups, and more than 40% cardiac grafts survived over 2 months. The splenic T cells isolated from recipients did not respond to restimulation of donor splenocytes in MLR, but did exhibit the capacity to proliferate in response to C3H splenocytes(third party).The levels of IL 2 and IFN ? decreased and the level of IL 10 increased in CTLA 4 Ig treated mice. Conclusion: Administration of CTLA 4 Ig can induce donor specific tolerance, which induce T subsets to polarize toward Th2 subset and hyporesponsiveness to alloantigen, and prolong the survival time of the cardiac grafts effectively.

BACKGROUND:Liver regeneration is the key factor influencing the prognosis of living donor liver transplantation. There has not been the research on special miRNA of liver regeneration after living donor liver transplantation. OBJECTIVE:To analyze the variation of miRNAs expression profile after rat reduced-size liver transplantation at certain time point, select and verify target miRNA which can provide targeting intervention strategies in liver regeneration after rat reduced-size liver transplantation and provide theoretical evidence for liver regeneration after living donor liver transplantation.METHODS:The reduced-size liver transplantation models were established. miRNAs microarray was used to detect miRNA expression. In differentialy expressed microRNAs, real-time quantitative PCR was utilized to detect target miRNAs. The credibility of miRNAs microarray results was verified. RESULTS AND CONCLUSION:Compared with rat liver tissue in the sham operation group, 11 miRNAs up-regulated in reduced-size liver transplantation, including let-7b-5p, let-7c-5p, miR-101a-3p, miR-103-3p, miR-130a-3p, miR-142-5p, miR-186-5p, miR-199a-3p, miR-21-5p, 221-3p and miR-34a-5p. Four miRNAs were down-regulated, including miR-26b-5p, miR-150-5p, miR-19a-3p and rno-miR-146-5p. PCR test further verified that miR-221-3p and miR-199a-3p expression changes approximated the chip results at 24, 48 hours and 1 week, indicating that results of miRNA microarray were believable. These results verified that it exists variation of miRNAs expression profile after rat reduced-size liver transplantation, which picked out and verified the target miRNAs.

BACKGROUND: Greater tuberosity of humerus, as the attachment point of rotator cuff, plays a vital role in shoulder.Neer and AO classification for proximal humeral fractures have been accepted extensively. However, the classification for single greater tuberosity fractures of the proximal humerus is little reported, and its fixation method remains controversial.OBJECTIVE: To explore the curative efficacy of the double-row suture anchors under arthroscopy for avulsion-type greater tuberosity fractures (Mutch type Ⅰ) METHODS: Clinical data of 24 patients with avulsion-type greater tuberosity fractures (Mutch type Ⅰ) undergoing double-row suture anchors under arthroscopy were analyzed retrospectively. The displacement distance of the greater tuberosity of humerus was measured on CT before and after fixation. The shoulder joint was evaluated by Constant-Murley Score and the University of California, Los Angeles score at baseline, 1, 3, 6 and 12 months postoperatively. Besides, the visual analogue scale scores were detected at baseline and 12 months postoperatively.RESULTS AND CONCLUSION: (1) Double-row suture anchors effectively improved the displacement of greater tuberosity and rotator cuff injury. (2) The patients accompanied by rotator cuff injury accounted for 79.16%. (3) The Constant-Murley Score and the University of California, Los Angeles scores were significantly improved at each time point (P < 0.05). The visual analogue scale scores after fixation were significantly superior to those before fixation (P < 0.05). (4) These results suggest that the double-row suture anchors under arthroscopy can effectively improve the displacement of greater tuberosity and alleviate the pain. Moreover, it is conductive for early recovery of the shoulder function with little trauma, so it is a good choice for avulsion-type greater tuberosity fractures (Mutch type Ⅰ).
