Objective To explore the role of fibrogenic cytokines and inflammatory cytokines in the pathogenesis of frozen shoulder. Methods From September, 2014 to April, 2016, 20 patients with frozen shoulder accepted arthroscopic surgery were included, ten of them were diagnosed as primary frozen shoulder (group A), the other ten were secondary frozen shoulder (group B). Other ten patients undergo-ing shoulder arthroscopy for instability (4 cases), rotator cuff injury (3 cases) and subacromial impingement (3 cases) were as the controls (group C). The mRNA levels of matrix metalloproteinase (MMP) 1, MMP3, tumour necrosis factor-α (TNF-α), interleukin (IL)-1, IL-6, IL-8, granulocyte-macrophage colony stimulating factor (GM-CSF) and M-CSF in synovium were analyzed with quantitative polymerase chain reaction. Results The expression of mRNA of MMP1, MMP3, TNF-α, IL-1, IL-6, IL-8, GM-CSF and M-CSF were more in group A and group B than in group C (P<0.05). There was no significant difference between group A and group B (P>0.05). Conclusion The fibro-genic cytokines and inflammatory cytokines may play a role in the pathogenesis of frozen shoulder.

BACKGROUND:Silk fibroin/mesoporous glass ceramic composites have been reported to exert satisfactory repair outcomes in bone defects and hold good biocompatibility. However, the biosafety and preparation methods are rarely reported. OBJECTIVE:To investigate the preparation method and treatment outcomes of silk fibroin/mesoporous bioactive glass ceramic in skul repair. METHODS:Thirty-two Sprague-Dawley rats were enrol ed to establish the skul defect models and were thenrandomized into two groups:fibroin/mesoporous glass ceramic materials and silk fibroin were respectively implanted into the defect region in experimental and control groups. At 4 and 8 weeks after implantation, the CT examination and histological observation were performed. RESULTS AND CONCLUSION:CT examination showed that at 4 weeks after implantation, the defect area in the experimental group diminished in size, showing more dense new bones. The defect area of the control group was reduced, and a smal amount of new bones were observed. At 8 weeks after implantation, bone defect repair was completed in the experimental group, but not in the control group. The bone volume in the experimental group was significantly larger than that in the control group at different time points after implantation (P<0.05). Hematoxylin-eosin staining found that at 4 weeks after implantation, in the experimental group, there was new bone between the implant and the bone, which did not cause inflammation;there were few new bones and fibrous tissues in the control group. At 8 weeks after implantation, many new bones formed in the experimental group, with similar morphology to the host bone and the scaffold was degraded completely. Conversely, the implant material stil existed in the control group. In conclusion, the silk fibroin/mesoporous glass ceramic composite can promote bone repair.

This study was aimed to compare different preparation methods of Wei-Chang Fu-Yuan (WCFY) De-coction, which is a self-made traditional Chinese medicine (TCM) decoction of our hospital, through the investiga-tion of difference in recovery time of gastrointestinal function after gynecological abdominal surgery. A total of 120 cases after gynecological abdominal surgery in our hospital between 2011 and 2012 were randomly divided into the treatment group and the control group, with 60 cases in each group. The hospital self-made WCFY Decoction was given to patients 8 hours after surgery in the treatment group and control group. Decoctions given to two groups were prepared with different methods. Decoction given to the treatment group was by the decoction ma-chine of multiple decoctions preparation. Decoction given to the control group was prepared as the traditional sin-gle dose decoction. The first anus flatus time was observed in both groups. The results showed that the flatus time of treatment group was 16 h and that of the control group was 13 h. The flatus time of patients from two groups was in skewed distribution, so the distance between the median and quartile was used to describe. The non-para-metric tests (Kolmogorov-Smirnov method) were used in the comparison of flatus time of two groups. There was statistical significance between two groups (P < 0.05). It was concluded that different preparation methods affect the clinical efficacy of WCFY Decoction. Compared with the traditional single dose decoction, the fist flatus time was postponed 3 hours by the decoction machine of multiple decoctions preparation. Therefore, with the widely using of decoction machine of multiple decoctions preparation today, the function of decoction machine should be improved and the program should be perfected in order to increase the clinical efficacy of this preparation method.
