CONTEXT Humeral torsion (HT) has been linked to various injuries and benefits. However, the exact interplay between HT, shoulder range of motion (ROM), competition level differences, and injury risk is unclear. OBJECTIVE To determine the relationship between HT, ROM, and injury risk in baseball players. Secondarily, to determine HT based on competition level. DATA SOURCES PubMed, Embase, Web of Science, CINAHL, and Cochrane databases were searched from inception until November 4, 2018. STUDY SELECTION Inclusion criteria consisted of (1) HT measurements and (2) arm injury or shoulder ROM. STUDY DESIGN Systematic review. LEVEL OF EVIDENCE Level 3. Selleck Temsirolimus DATA EXTRACTION Two reviewers recorded patient demographics, competition level, HT, shoulder ROM, and injury data. RESULTS A total of 32 studies were included. There was no difference between baseball players with shoulder and elbow injuries and noninjured players (side-to-side HT difference mean difference [MD], 1.75 [95% CI, -1.83 to 2.18]; dominant arm MD, 0.17 [95% CI, -1.83 to 2.18]). Meta-regression determined that for every 1° increase in shoulder internal rotation (IR), there was a subsequent increase of 0.65° in HT (95% CI, 0.28 to 1.02). HT did not explain external rotation (ER ROM 0.19 [95% CI, -0.24 to 0.61]) or horizontal adduction (HA ROM 0.18 [95% CI, -0.46 to 0.82]). There were no differences between HT at the high school, college, or professional levels. CONCLUSION No relationship was found between HT and injury risk. However, HT explained 65% of IR ROM but did not explain ER ROM or HA ROM. There were no differences in HT pertaining to competition level. The majority of IR may be nonmodifiable. Treatment to restore and maintain clinical IR may be important, especially in players with naturally greater torsion. HT adaptation may occur prior to high school, which can assist in decisions regarding adolescent baseball participation.Bone defects caused by various causes remain a major problem in orthopaedic clinic. A number of different treatments have been developed and proposed, but until now, none has proven to be completely satisfactory. For 26 patients with bone defects but limited autologous bone source or allogeneic bone graft failure, we used individual tissue-engineered bones (iTEBs) for repairing, which were constructed by autologous bome marrow mesenchymal stem cells (BMSCs) and allogenic decalcified bone matrix (DBM) scaffolds. The clinical outcomes, including efficacy and safety, were evaluated by radiological examinations, postoperative function recovery score and laboratory tests. 26 patients, including 18 males and 8 females, were followed up for an average of 10 years to analyze the long-term outcome. The mean healing time for patients with lacunar bone defects was 3.87±2.01 months (range, 2-9 months) and that for structural bone defects was longer than 12 months. The Musculoskeletal Tumor Society (MSTS) functional evaluation system and the Barthel Index (BI) scores were significantly improved during the long-term follow-up. The WBC, ESR, CRP, Complement, Immunoglobulins, liver and renal functions were not significantly affected by bone grafting. One patient with bone cyst relapsed at 3 years postoperatively and achieved bone healing after re-transplantation. No tumorigenesis, tumor metastasis or blood transmissible disease was found in the whole process. The results demonstrated that iTEBs were effective and safe for repairing bone defects in the long period, especially for those with lacunar bone defects and limited autograft source.Human basic fibroblast growth factor (hbFGF) is involved in a wide range of biological activities that affect the growth, differentiation, and migration. Due to its wound healing effects and therapy, hbFGF has the potential as therapeutic agent. Therefore, large-scale production of biologically active recombinant hbFGF with low cost is highly desirable. However, the complex structure of hbFGF hinders its high-level expression as the soluble and functional form. In the present study, an efficient, cost-effective, and scalable method for producing recombinant hbFGF was developed. The modified collagen-like protein (Scl2-M) from Streptococcus pyogenes was used as the fusion tag for producing recombinant hbFGF for the first time. After optimization, the expression level of Scl2-M-hbFGF reached approximately 0.85 g/L in the shake flask and 7.7 g/L in a high cell-density fermenter using glycerol as a carbon source. Then, the recombinant Scl2-M-hbFGF was readily purified using one-step acid precipitation and the purified Scl2-M-hbFGF was digested with enterokinase. The digested mixture was further subject to ion-exchange chromatography, and the final high-purity (96%) hbFGF product was prepared by freeze-drying. The recovery rate of the whole purification process attained 55.0%. In addition, the biological activity of recombinant hbFGF was confirmed by using L929 and BALB/c3T3 fibroblasts. Overall, this method has the potential for large scale production of recombinant hbFGF.Background Anastomotic leakage (AL) is arguably the most troublesome complication of anterior resection (AR). In recent years, however, indocyanine green (ICG) fluorescence imaging has been recently used to evaluate blood flow in the anastomosis site, and it has been suggested that AL may be predicted. We reported the effectiveness of predicting AL in colorectal cancer surgery by observing a quantitative laparoscopic ICG fluorescence imaging for the first time. The purpose of this study was to predict the risk of postoperative AL by quantitative laparoscopic ICG fluorescence imaging focused on the rectal stamp, which is one of the major causes of AL in AR, and to construct diverting stoma (DS) only in appropriate cases. Methods We studied the 25 patients who underwent elective laparoscopic AR for rectal cancer at our hospital between July 2016 and June 2017. Before enforcing double-stapling technique anastomosis, we injected ICG intravenously, and laparoscopically evaluated blood flow on the rectal stump. We analyzed quantitatively the relationship between various parameters and AL. Results Median T0, from when the ICG was injected intravenously and the ICG disappeared from the injection route to the rise of the histogram of intensity, in AL group was significantly longer than that in non-AL group (P = .03). There were no other significant differences between AL and non-AL groups. Conclusions T0 was longer in patients with AL than in those without. If prolonged T0 can be recognized intraoperatively, it will be possible to construct DS for appropriate patients only.
