BACKGROUND:Titanium elastic intramedullary nailing for the treatment of significantly displaced midshaft clavicle fractures has the characteristics of minimally invasive and elastic fixation.The displacement of the fracture is closely related to the later function.However,there are few studies on the three-dimensional displacement analysis of the fracture ends before surgery and after intramedullary fixation such as titanium elastic intramedullary nailing.OBJECTIVE:To explore the three-dimensional displacement of fracture ends after midshaft clavicle fracture and fixation with titanium elastic intramedullary nails,and to analyze the risk factors.METHODS:A total of 91 patients with midshaft clavicle fracture(fracture end shortening ≥15 mm)admitted to Wendeng Orthopedic Hospital of Shandong Province from April 2019 to April 2024 were selected,including 57 males and 34 females,aged(51.73±10.21)years old.All patients received closed reduction and internal fixation with titanium elastic intramedullary nail.CT scans of the affected clavicle were performed before and on the first day after surgery.The CT data were imported into Mimics software for modeling.The length of the clavicle,lateral displacement of the fracture end,and rotation of the distal end of the fracture along the X,Y,and Z axes were measured and recorded before and after surgery.Pearson correlation coefficient was used for correlation analysis of various parameters,and generalized linear regression was used to evaluate risk factors.RESULTS AND CONCLUSION:(1)Preoperatively,the variable that increased the risk of lateral displacement was the number of comminuted bone fragments,the variable that increased the risk of shortening displacement was male patients,and the variable that increased the risk of Z-axis rotation was the left limb.Shortening displacement was significantly positively correlated with lateral displacement(r=0.715,P＜0.001);shortening displacement was significantly positively correlated with X-axis rotation displacement and Y-axis rotation displacement(r=0.265,P=0.028;r=0.303,P=0.011);lateral displacement was significantly positively correlated with Y-axis rotation and Z-axis rotation(r=0.258,P=0.032;r=0.250,P=0.038);X-axis rotation was significantly positively correlated with Y-axis rotation(r=0.382,P=0.001),and Z-axis rotation was significantly positively correlated with Y-axis rotation(r=0.280,P=0.020).(2)Postoperatively:The number of scapula fractures and comminuted bone fragments were variables that increased the risk of postoperative shortening and lateral displacement:Preoperative X-,Y-,and Z-axis rotation displacements were risk variables that increased postoperative X-,Y-,and Z-axis rotation displacements,respectively.Postoperative lateral displacement was significantly positively correlated with postoperative shortening and displacement(r=0.584,P=0.000),and postoperative lateral displacement was also significantly positively correlated with postoperative Y axis rotation and Z axis rotation(r=0.360,P=0.002;r=0.250,P=0.038).Postoperative Y axis rotation was significantly positively correlated with postoperative Z axis rotation(r=0.248,P=0.040).(3)The results showed that the three-dimensional displacement of the clavicle end before and after surgery was affected by many factors,especially the number of comminuted bone fragments,scapula fractures,gender,and original rotation displacement.At the same time,there were complex correlations between various displacements,especially the correlation between shortening displacement and lateral displacement was the strongest.

Conclusions:The duration of disease, number of involved joint, serum uric acid level, unhealthy lifestyles and lipid metabolism disorders are the independent risk factors of subcutaneous tophus among hospitalized gout patients.

Objective:To investigate the effect of CIRc_0000267 on proliferation, migration, invasion and apoptosis of gastric cancer cells in vitro.Methods:Gastric cancer cell lines with circ_0000267 knockdown and miR-661 overexpression were constructed in vitro, and the expressions of circ_0000267, miR-661 and NGAL mRNA in gastric cancer tissues and cells were detected by qRT-PCR. Cell proliferation, migration, invasion and apoptosis were detected by clonogenesis, Transwell chamber and flow cytometry, and related protein expression was detected by Western blot. Online prediction combined with double luciferase assay and RNA pull down assay was used to verify the targeting relationship between circ_0000267, miR-661 and NGAL. Tumogenesis assay in nude mice was used to observe the effect of circ_0000267 knockout on the growth of gastric cancer cells in vivo. Results:Circ_0000267 was highly expressed in gastric cancer tissues and cells. Knockdown circ_0000267 inhibited the proliferation, migration and invasion of gastric cancer cells and promote apoptosis. Circ_0000267 targeted miR-661, and inhibition of miR-661 partially reversed the effect of circ_0000267 on gastric cancer cells. NGAL was the target gene of miR-661, and overexpression of miR-661 regulated the proliferation, migration, invasion and apoptosis of gastric cancer cells by inhibiting NGAL. Knockdown circ_0000267 targeting miR-661 inhibited NGAL expression in gastric cancer cells; Knockdown circ_0000267 inhibited the growth of gastric cancer cells in vivo.Conclusions:Circ_0000267 may regulate the proliferation, migration, invasion and apoptosis of gastric cancer cells and inhibit the growth of tumors in vivo by regulating the expression of miR-661/NGAL.

Objective:To evaluate the precise guidance of intraoperative ultrasound for closed reduction and fixation with intramedullary titanium elastic nail (TEN) in the treatment of clavicle fractures.Methods:The data of 40 patients with fresh clavicle fracture were retrospectively analyzed who had undergone closed reduction and TEN fixation under precise guidance of intraoperative ultrasound at Department of Emergency Trauma, Shandong Wendeng Osteopathic Hospital from January 2017 to March 2019. They were 25 males and 15 females, aged from 25 to 68 years (average, 52.1 years), with 27 cases on the left side and 13 on the right. Reduction and fixation of the fracture was monitored during operation to avoid iatrogenic injuries to the subclavian brachial plexus nerve, subclavian artery and vein and thoracic cavity. The Neer scoring was used at the last follow-up to assess shoulder joint function and complications were recorded.Results:Closed reduction and TEN fixation was completed uneventfully in all the 40 patients under precise guidance of intraoperative ultrasound. The operation time ranged from 20 to 56 min, averaging 36 min; the blood loss from 10 to 35 mL, averaging 22 mL. No injury occurred to the subclavian brachial plexus, subclavian artery or vein, or thoracic cavity. The 40 patients were followed up for 4 to 6 months (average, 4.8 months). All fractures achieved bony union, with no displacement or breakage of internal fixation, or fracture malunion. At the last follow-up, the shoulder joint function was good, with Neer scores ranging from 85 to 95 points (average, 93.1 points).Conclusion:The precise guidance of intraoperative ultrasound improves surgical accuracy and safety, making the closed reduction and TEN fixation a safe and minimally invasive treatment for clavicle fractures.

Four hundred and four male patients with primary gout were enrolled. According to the degree of nonalcoholic fatty liver diseases (NAFLD), the patients were divided into simple gout ( n=121), gout combined with mild NAFLD ( n=149) and gout combined with moderate-severe NAFLD ( n=134). The height, weight, waist, hip, blood pressure and blood biochemistry parameters of patients were measured. The degree of NAFLD was negatively correlated with the age of patients in three groups. The BMI, ratio of waist/hip, count of red cells, hemoglobin, hematocrit, red blood cell distribution width ( SD and CV), triglyceride, alanine aminotransferase and HOMA-IR were increased with the increasing of NAFLD severity (all P<0.05). Red blood cell count, hemoglobin, alanine aminotransferase, serum uric acid increased with the increasing of NAFLD severity (all P<0.05). Platelet, serum urea nitrogen and serum creatinine were decreased with the increase of NAFLD severity. Logistic regression showed that BMI, hemoglobin and HOMA-IR were independent risk factors for NAFLD. The prevalence and the severity of NAFLD was increased with increasing quadrates of hemoglobin. Taking group Q1 as a control, OR of NAFLD in group Q2 was 1.166(95 %CI:0.638-2.133), OR in group Q3 was 2.011(95 %CI:1.122-3.605)and OR in group Q4 was 3.120(95 %CI:1.613-6.034). The result indicates that hemoglobin levels are associated with the development and the severity of NAFLD in male patients with primary gout.
