Circular RNA AFF4 modulates osteogenic differentiation in BM-MSCs by activating SMAD1/5 pathway through miR-135a-5p/FNDC5/Irisin axis.

Bone marrow-derived mesenchymal stem cells (BM-MSCs), the common progenitor cells of adipocytes and osteoblasts, have been recognized as the key mediator during bone formation. Herein, our study aim to investigate molecular mechanisms underlying circular RNA (circRNA) AFF4 (circ_AFF4)-regulated BM-MSCs osteogenesis. BM-MSCs were characterized by FACS, ARS, and ALP staining.

[Analysis of related factors of deep venous thrombosis after spinal cord injury].

Objective: To explore the high-risk factors of deep vein thrombosis (DVT) formation in patients after spinal cord injury (SCI) and to provide some reference value for the prevention of DVT.

Methods: Eighty-five patients with spinal cord injury caused by thoracolumbar burst fracture from January 2016 to December 2017 were selected as subjects. All patients were followed up for 6 months, of which 5 cases were lost and 80 cases were finally included.

A biopsychosocial model of resilience for breast cancer: A preliminary study in mainland China.

Purpose: Patients diagnosed with breast cancer exhibited critical biopsychosocial functions following surgery or adjuvant treatment; therefore, it is important that they exhibit resilience. A Resilience Model for Breast Cancer (RM-BC) was developed using Chinese breast cancer patients to increase our understanding of how resilience outcomes are positively and negatively affected by protective and risk factors, respectively.

Methods: Chinese women with breast cancer completed the questionnaires within 1 week of beginning treatment.

Psychometric properties of the Chinese version of resilience scale specific to cancer: an item response theory analysis.

Objective: Classic theory test has been used to develop and validate the 25-item Resilience Scale Specific to Cancer (RS-SC) in Chinese patients with cancer. This study was designed to provide additional information about the discriminative value of the individual items tested with an item response theory analysis.

Methods: A two-parameter graded response model was performed to examine whether any of the items of the RS-SC exhibited problems with the ordering and steps of thresholds, as well as the ability of items to discriminate patients with different resilience levels using item characteristic curves.

The role of RANKL/RANK/OPG system in the canine model of hip periprosthetic infection osteolysis.

Purpose: We aimed to investigate whether the RANKL/RANK/OPG system is associated with the incidence of periprosthetic osteolysis with septic loosening, and to investigate the differences of RANKL/RANK/OPG system expression in synovial fluid surrounding the normal and septic loosening hip prosthesis in canine models.

Methods: Twelve healthy adult mongrel canines were divided into two groups: experimental and control. Femoral head and stem replacements were conducted on the right side in both groups.

[Establishment of arthroscopic trans-septal approach and its clinical application].

Objective: To investigate the method and result of arthroscopic trans-septal approach (ATS).

Methods: Ten fresh cadaveric knees were prepared for anatomical study about the posterior septum, and 65 posterior compartment arthroscopy of the knees were performed to view the structure of the posterior septum. The initial diagnosis included: rheumatoid arthritis, pigmented villonodular synovitis, osteoarthritis, loose body or foreign body in the posterior compartment, posterior cruciate ligament (PCL) injury or avulsion fracture, posterior horn tear of meniscus, undiagnosed swollen knee with pain and effusion, osteochondritis dissecans, pyogenic arthritis, gout.

[Study on the patterns of TCM syndrome differentiation of 900 patients with posthepatitic cirrhosis].

Objective: To investigate the formula for TCM syndrome pattern differentiation in patients with posthepatitic cirrhosis.

Methods: Factors analysis, C mean clustering and fuzzy comprehensive assessment were used for analyzing the basic information, including clinical symptoms and signs, obtained from 900 patients with posthepatitic cirrhosis to establish the formula for syndrome pattern differentiation through collecting the syndromic factors.

Results: Multivariate statistic analysis showed the syndromic factors could be classified into two categories: the common characteristics related factors, which reflected the basic pathology of cirrhosis as qi deficiency and blood stasis, and the factors for differentiating 5 syndrome patterns (Gan-Shen yin-deficiency, dampness-heat accumulation, stasis-heat accumulation, Gan-qi stagnation with Pi-deficiency, and Pi-Shen qi-deficiency), which reflected the different pathological features of different syndrome patterns, showing the complexity and polymorphism of syndrome construction.
