Background:Diagnosis of liver cirrhosis in early stage with early intervention may stabilize disease progression, avoiding or delaying the occurrence of decompensation. Seeking non-invasive serum biomarkers is becoming an important topic in the diagnosis and assessment of liver cirrhosis. Aims:To study the value of serum miR-192 and miR-29a as non-invasive biomarkers for the diagnosis of liver cirrhosis. Methods:Differentially expressed serum miRNAs between patients with liver cirrhosis and healthy controls were screened through online literature retrieval and then confirmed by real-time PCR. Serum levels of two confirmed miRNAs,miR-192 and miR-29a were analyzed in 120 patients with liver cirrhosis and 76 healthy volunteers by real-time PCR. A mathematical model of combined detection of miR-192 and miR-29a for diagnosis of liver cirrhosis was established by binary logistic regression. The diagnostic performance of various non-invasive serum indicators was evaluated by ROC curve analysis. Results:Compared with healthy controls,expression level of serum miR-192 in cirrhotic patients was significantly increased and that of serum miR-29a was significantly reduced(P ﹤ 0. 001). The diagnostic performance of risk score obtained from mathematical model of combined detection of serum miR-192 and miR-29a was superior to that of single miRNA detection or other non-invasive serum indicators,such as APRI,FIB-4 and ARR,the areas under ROC curve of the above mentioned indicators were 0. 968,0. 887,0. 933,0. 796,0. 793,and 0. 571,respectively. Serum levels of miR-192,miR-29a and the risk score of their combined detection were significantly correlated with the stage of liver cirrhosis according to the Child-Pugh classification( P ﹤ 0. 05). Conclusions:Serum miR-192,miR-29a and the risk score of their combined detection might be novel non-invasive biomarkers for the diagnosis and assessment of liver cirrhosis.

Objective To explore the short?term functional outcomes of the reconstruction of the proximal humerus by re?verse shoulder arthroplasty after tumor rescetion. Methods 8 patients who underwent reverse shoulder arthroplasty after tumor resection between January 2013 and December 2014. 5 were female and 3 were male, mean aged was 38 years old (25-61). 2 chon?drosarcomas and 6 giant cell tumors. Enneking stageing of 2 cases with chondrosarcoma were stageⅠB and stageⅡB. 6 giant cell tumors were Campanacci stage 3, meanwhile 3 cases had pathological fractures. The deltoid and axillary nerve were intact in all patients by image analysis before the operation. The proximal humerus was resected according to Malawer typeⅠresection. Then reverse shoulder arthroplasty reconstruction and bone graft was performed. The follow?up was scheduled, and the patient received X?ray examination of the shoulder. The range of motion of the shoulder was measured, the Constant?Murley score and musculoskel?etal tumor society(MSTS) score was recorded. Results The mean duration of the operation was 2.7 h (2-3.5 h). The bleeding in the operation was 510 ml (300-850 ml). The mean length of humerus resection was 8 cm (6-10 cm). The allografts were used in 7 cases and reimplantation after tumor bone deactivation was used in one. The latissimus dorsi transfer were performed in 2 cases. The rotator cuff were resected 1-1.5 cm from the great and lesser tubercles. The follow?up was 13 months (3-26 months). No infec?tion, dislocation, or loosening of prosthesis was found by the last follow?up. The X?ray showed the case who received reimplanta?tion after tumor bone deactivation had achieved bone union 1 year postoperation,7 cases received allograft had still nonunion at the host?graft junction. Bone resorption were found in all cases in different extent but the prosthesis were stable. No local recur?rence of the tumor was found. At last follow?up, active abduction was 155° (100°-175° ) and active forward elevation was 150° (115°-170°) and Constant?Murley score was 76%(68%-87%). The MSTS score was 92%(87%-97%). Conclusion The func?tional outcomes of the reconstruction of the proximal humerus by reverse shoulder arthroplasty after tumor rescetion was satisfied in early period. The reverse shoulder arthroplasty can be used in younger patient, but long?term results need further study.
