Objective To explore the immunomodulation property of bone marrow-derived mesenchymal stem cells (BMSCs) from Sprague-Dawley (SD) rats after they are isolated, cultured and identified by surface marker and differentiation potential examination. Methods BMSCs were isolated from femur and tibia of SD rats and passaged by trypsinization. The surface markers of the 3rd passage BMSCs were detected by flow cytometry and the capacity of their adipocyte and cartilage differentiation were examined. In order to explore the immunomodulation property of BMSCs, allogeneic spleen T cells of Wi?star rats were co-cultured with BMSCs through either cell-to-cell contact or transwell, then its effect on the T cell subsets and related mechanism was also examined. Results BMSCs were mainly spindle-shaped in culture. Surface marker detec?tion showed that BMSCs expressed high levels of CD29, CD44 and CD90 but no CD34 nor CD45 at the third generation. Un?der specific condition, BMSCs could differentiate into adipocytes and chondrocytes. The CD8+effector T cells (Teffs) decreas?es effectively and the CD4+CD25+regulatory T cells (Tregs) increased remarkably when BMSCs were co-cultured with allo?geneic spleen T cells for 48 hours. The expressions of IL-10 and TGF-β1 of BMSCs significantly increased after co-culture with T cells, and this effect was more obvious in cell-to-cell contact group. Conclusion The immunomodulation property of BMSCs were presumably function through cell-to-cell contacts and cytokine secretion.

Objective:To investigate the risk factors of rotator cuff tears combined with long head of bicep tendon (LHBT) lesion and its effects on preoperative function.Methods:From January 2016 to January 2020, there were 680 patients with rotator cuff tears, including 260 males and 420 females, were included. The average age was 56.1±8.7 (range 27-74 years). There were 250 cases on the left side and 430 cases on the right side. There were 436 cases on the main side, while 274 cases had definite trauma before operation. The following were the Post rotator cuff tears classification, 133 cases in partial injury, 473 cases in small and medium size of rotator cuff tears, 74 cases in large and massive size of rotator cuff tears. The Habermayer-Walch classification of LHBT lesions was as following, 302 cases in type 0 (normal), 216 cases in type 1 (tendonitis), 29 cases in type 2 (dislocation and subluxation), 104 cases in type 3 (partial tear), 20 cases in type 4 (complete tear) and 9 cases in type 5 (SLAP injury above type II). The patient with rotator cuff tears were divided into partial tears group, medium and small tears group, large and massive tears group according to the classification of Post. The visual analogue scale (VAS), simple shoulder test (SST), Constant-Murley function score and the score of the University of California Los Angeles (UCLA) were recorded. The differences in age, sex, main side, trauma and LHBT lesion in patients with three types of rotator cuff tears were analyzed. The preoperative pain and function scores of patients with or without LHBT lesions in various rotator cuff tears were compared among the groups by t-test. The age, sex, main side, with trauma or not, and the classification of rotator cuff tears were analyzed by Logistic regression to investigate the risk factors of patients with rotator cuff tears with LHBT lesions. Results:There were 378 cases (55.6%) with LHBT lesions in 680 patients with rotator cuff tears, including 216 cases of tendinitis (57.1%), 104 cases of partial tear (27.5%), 29 cases of dislocation and subluxation (7.7%), 20 cases of complete tear (5.3%) and 9 cases of SLAP injury (2.4%). The incidence of partial injury, small and medium injury, large and massive rotator cuff injury combined with LHBT lesions were 35.3% (47/133), 57.5% (272/473) and 79.7% (59/74) respectively. The preoperative VAS score, UCLA score, Constant-Murley score and SST score were 5.20±1.52, 14.81±4.12, 41.45±4.93 and 4.56±1.96 respectively in rotator cuff tears group and 5.29±1.65, 14.34±4.01, 41.60±5.88, 4.47±1.97 in LHBT group ( P>0.05). In the partial rotator cuff tears group, the VAS score was 5.16±1.41 in patients with simple rotator cuff tears and 5.68±1.46 in patients with LHBT lesion ( t=2.004, P=0.047). Regression analysis showed that age ≥60 years and rotator cuff tears degree were the risk factors for rotator cuff tears with LHBT ( P<0.001). Conclusion:It is common for patients to have rotator cuff tears with LHBT lesions. The more severe the rotator cuff tears are, the higher the incidence of LHBT lesions will be. Patients with rotator cuff tears aged 60 and above are more likely to have LHBT lesions. However, the complications of LHBT could not affect the preoperative pain and functional scores of patients with rotator cuff tears.

E2F transcription factor 1 (E2F1) is a major member of the E2F transcription factor family and participates in a wide range of physiological regulatory processes, such as cell cycle, survival, apoptosis, and metabolism. It is proved that the activity of E2F1 is related to the G1/S phase regulation of the cell cycle dependent on tumor suppressor retinoblastoma protein (RB). Recent studies have shown that E2F1 is highly expressed in prostate cancer cells, manifested as an oncogene, and its expression level is closely related to the occurrence, development, and poor clinical prognosis of prostate cancer. Androgen receptor (AR) is the main driving factor for the growth and progression of prostate cancer, and the changes of AR pathway play a key role in the pathological progression of prostate cancer. This article provide a systematic and comprehensive summary on recently published articles to review the role of the E2F1 pathway in prostate cancer.
