RESUMO
OBJECTIVE: Platelet to albumin ratio (PAR) and prognostic nutritional index (PNI) are potential indicators for evaluating nutritional and inflammatory status. This study aimed to examine the relationship between PAR and PNI and the acute complicated course of acute hematogenous osteomyelitis (AHO). METHODS: AHO patients were divided into the simple course group and the acute complicated course group. The patient's gender, age, site of infection, body temperature, laboratory results, and pathogen culture results were collected and compared. Multivariate logistic regression analysis was used to determine the independent risk factors of the acute complicated course group. The receiver operating characteristic curve was applied to determine the optimal cut-off value. RESULTS: In total, 101 AHO patients with a median age of 7.58 years were included. There were 63 cases (62.4 %) in the simple course group and 38 cases (37.6 %) in the complicated course group. Binary logistic regression analysis revealed that PAR and PNI were independent risk factors for predicting the acute complicated course of AHO (p = 0.004 and p < 0.001, respectively). Receiver operating characteristic curve analysis demonstrated that the combination of PAR and PNI had an area under the curve of 0.777 (95 % CI: 0.680-0.873, p < 0.001) with a cut-off value of 0.51. CONCLUSIONS: The incidence of acute complicated courses was significantly higher in patients with high PAR and low PNI. A combined factor greater than 0.51, derived from PAR and PNI measurements within 24 h of admission, may be useful for predicting AHO patients who are likely to develop severe disease.

BACKGROUND: Hip dysplasia is one of the most prevalent disorders in children and one of the three primary congenital orthopedic deformities. Although there are numerous existing methods (e.g., CT, MRI and arthrography) for early identification of hip dysplasia, their diagnostic criteria differ widely. It is critical to establish a safe, accurate, and reliable way for early diagnosis and treatment of hip dysplasia. OBJECTIVE: This study aimed to analyze the diagnostic efficacy of high-frequency ultrasound (HFU) for congenital developmental hip dysplasia and hip dislocation and to provide a reference for the early diagnosis of congenital hip dysplasia in the future. METHODS: A total of 104 infants and children suspected of having congenital hip dislocation or developmental hip dysplasia admitted to our hospital from April 2019 to August 2022 were enrolled as study subjects. All the infants and children were subjected to HFU and X-ray examination in our hospital. The diagnostic efficacy of HFU for congenital hip dysplasia was observed using X-ray as the gold standard. RESULTS: HFU confirmed 79 cases of congenital hip dysplasia, while X-ray confirmed 71 cases. The sensitivity and specificity of HFU were 77.42% and 83.33%, respectively, in the diagnosis of congenital developmental hip dysplasia, 76.47% and 96.55% in the diagnosis of congenital hip dislocation, and 77.22% and 60% in the diagnosis of congenital hip abnormality, which is very close to the gold standard. According to statistics on infants and children, the majority of patients were girls, and the left joint was more likely to be affected. CONCLUSION: HFU has excellent diagnostic efficiency for congenital developmental hip dysplasia and hip dislocation, which can be considered an early assessment method for congenital hip dysplasia in the future.
RESUMO
Objective: To compare the effectiveness of ultrasound- and arthrography-assisted Kirschner wire fixation in the treatment of Jakob type â ¡ lateral condylar humerus fracture (LCHF) in children. Methods: A clinical data of 101 children with Jakob type â ¡ LCHF, who met the selection criteria and were admitted between April 2021 and April 2022, was retrospectively analyzed. Of them, 47 cases were treated with ultrasound-assisted Kirschner wire fixation (group A), and 54 cases with arthrography-assisted surgery (group B). There was no significant difference in gender, age, cause of injury, fracture side, and disease duration between groups (P>0.05). Intraoperative fluoroscopy times, operation time, and hospital stay, Flynn elbow joint function score, and postoperative complications were recorded and compared between groups. X-ray examination was performed to observe the healing of fracture, and measure the carrying angle and the shaft-condylar angle (SCA). Results: The success rate of closed reduction was significantly higher in group A than in group B (P<0.05), and the intraoperative fluoroscopy times was significantly less in group A than in group B (P<0.05). There was no significant difference in operation time and hospital stay between groups (P>0.05). All children in both groups were followed up 12-18 months, with an average of 13.6 months. X-ray reexamination showed that the fractures of both groups healed, and the difference in healing time was not significant (P>0.05). At last follow-up, there was no significant difference in carrying angle and SCA between unaffected side and affected side in both groups and between groups A and B in affected side (P>0.05). There was no significant difference in Flynn elbow joint function score between groups (P>0.05). There were 18 cases of lateral spurs formation in group A, 1 case of pinning infection and 26 cases of lateral spurs formation in group B, and there was no significant difference in the incidence of the above complications (P>0.05). Conclusion: Compared with the arthrography, the ultrasound-assisted Kirschner wire fixation in the treatment of Jakob type â ¡ LCHF in children can avoid the open reduction and decrease the number of intraoperative fluoroscopy, and obtain the good effectiveness.

Objective: To explore the effectiveness of thumb blocking technique through closed reduction of ulnar Kirschner wire threading in the treatment of Gartland type â ¢ supracondylar humerus fractures in children. Methods: The clinical data of 58 children with Gartland type â ¢ supracondylar humerus fractures treated with closed reduction of ulnar Kirschner wire threading by thumb blocking technique between January 2020 and May 2021 were retrospectively analyzed. There were 31 males and 27 females with an average age of 6.4 years ranging from 2 to 14 years. The causes of injury were falling in 47 cases and sports injury in 11 cases. The time from injury to operation ranged from 24.4 to 70.6 hours, with an average of 49.6 hours. The twitch of ring and little fingers was observed during operation, the injury of ulnar nerve was observed after operation, and the healing time of fracture was recorded. At last follow-up, the effectiveness was evaluated by Flynn elbow score, and the complications were observed. Results: There was no twitch of the ring and little fingers when the Kirschner wire was inserted on the ulnar side during operation, and the ulnar nerve was not injured. All children were followed up 6-24 months, with an average of 12.9 months. One child had postoperative infection in the operation area, local skin redness and swelling, and purulent secretion exudation at the eye of the Kirschner wire, which was improved after intravenous infusion and regular dressing change in the outpatient department, and the Kirschner wire was removed after the initial healing of the fracture; 2 children had irritation at the end of the Kirchner wire, and recovered after oral antibiotics and dressing change in the outpatient department. There was no serious complication such as nonunion and malunion, and the fracture healing time ranged from 4 to 6 weeks, with an average of 4.2 weeks. At last follow-up, the effectiveness was evaluated by Flynn elbow score, which was excellent in 52 cases, good in 4 cases, and fair in 2 cases, and the excellent and good rate was 96.6%. Conclusion: The treatment of Gartland type â ¢ supracondylar humerus fractures in children by closed reduction and ulnar Kirschner wire fixation assisted with thumb blocking technique is safe and stable, and will not cause iatrogenic ulnar nerve injury.

Objective: To compare the effectiveness of open reduction and internal fixation with plate and closed reduction and internal fixation with Kirschner wire (K-wire) in the treatment of intra-articular displaced calcaneal fractures in older children. Methods: A clinical data of 35 older children (37 feet) with intra-articular displaced calcaneal fractures who were admitted between November 2014 and November 2020 and met the selection criteria were retrospectively analyzed. Among them, 19 cases (20 feet) underwent open reduction and internal fixation with plate (plate group), and 16 cases (17 feet) underwent closed reduction and internal fixation with K-wire (K-wire group). There was no significant difference in gender, age, cause of injury, side and type of fracture, and time from injury to admission, and preoperative calcaneal Gissane angle and Böhler angle ( P>0.05). The postoperative calcaneal Gissane angle, Böhler angle, complications, and fracture healing were compared between the two groups. The ankle function was evaluated based on the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot scoring system. Results: Incision necrosis occurred in 1 foot in the plate group after operation, which healed after symptomatic treatment; the other incisions in the two groups healed by first intention. All children were followed up 12-39 months (mean, 19 months). X-ray films showed that the fractures in both groups healed; the healing time was (2.65±0.71) months in the plate group and (2.24±1.38) months in the K-wire group respectively, with no significant difference ( t=1.161, P=0.253). At last follow-up, the calcaneal Gissane angle and Böhler angle returned to normal; and the difference between pre- and post-operation in the two group was significant (P<0.05), but there was no significant difference between the two groups in the difference between before and after operation ( P>0.05). In the plate group, the plate was removed at 11-22 months after operation (mean, 16.8 months). At last follow-up, the AOFAS ankle-hindfoot score in the plate group was 91.2±5.1, which was significantly higher than that in the K-wire group (86.9±6.1) ( t=2.316, P=0.027). The ankle function was rated as excellent in 15 feet, good in 4 feet, and fair in 1 foot in the plate group, and excellent in 14 feet and good in 3 feet in the K-wire group, and the difference between the two groups was not significant ( Z=1.712, P=0.092). Conclusion: For intra-articular displaced calcaneal fracture in older children, the open reduction and internal fixation with plate and closed reduction and internal fixation with K-wire can achieve good effectiveness, but the former has better recovery of ankle function.

Circular RNA (circRNA) is a unique type of endogenous RNA. It does not have free 3 'or 5' ends, but forms covalently closed continuous rings. Rheumatoid arthritis (RA) is a common chronic autoimmune joint disease, characterized by chronic inflammation of the joint synovial membrane, joint destruction, and the formation of pannus. Although the pathogenesis of rheumatoid arthritis remains incompletely understood, a growing amount of research shows that circRNA has a close relationship with RA. Researchers have found that abnormally expressed circRNAs may be associated with the occurrence and development of RA. This article reviews the inflammatory immune, functions, mechanisms, and values of the circRNAs in RA to provide new ideas and novel biomarkers for the diagnosis and treatment of RA.
RESUMO
BACKGROUND: As a malignant tumor, the progression of osteosarcoma (OS) is mediated by multiple regulators, including circular RNAs (circRNAs). However, the role of circ_0000885 in OS is unclear. MATERIALS AND METHODS: Quantitative real-time polymerase chain reaction (qRT-PCR) was applied to detect the expression of circ_0000885, miR-1294 and fibroblast growth factor receptor 1 (FGFR1). Cell proliferation was evaluated using 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyltetrazolium bromide (MTT) assay and colony formation assay. Flow cytometry and transwell assay were employed to determine the cell cycle distribution, cell migration and invasion, respectively. Moreover, the relationship between miR-1294 and circ_0000885 or FGFR1 was confirmed by dual-luciferase reporter assay. The protein level of FGFR1 was assessed via Western blot (WB) analysis. Animal experiments were used to verify the effect of circ_0000885 silencing on OS tumor growth in vivo. RESULTS: Circ_0000885 level was increased in OS tissues and cells. Knockdown of circ_0000885 repressed the proliferation, migration, invasion and induced cell cycle arrest in OS cells. There was a binding relationship between miR-1294 and circ_0000885, and miR-1294 inhibitor could reverse the inhibitory effect of silenced circ_0000885 on OS progression. MiR-1294 could target FGFR1, and overexpressed FGFR1 could invert the suppression effect of miR-1294 mimic on OS progression. Silencing of circ_0000885 hindered FGFR1 expression, while this effect could be recovered by miR-1294 inhibitor. In addition, circ_0000885 knockdown reduced OS tumor growth via regulating the FGFR1 expression by sponging miR-1294 in vivo. CONCLUSION: Circ_0000885 played an active role in OS progression, indicating that it might be a potential target for OS therapy.
