RESUMEN
BACKGROUND: Osteoarthritis (OA) is a chronic disease of the bones and joints that commonly affects middle-aged and elderly individuals, characterized by the degeneration of articular cartilage and inflammation of the joints. The molecular mechanisms of OA urgently need to be further examined. Our study intended to uncover circ-NFKB1/miR-203a-5p/ERBB4 axis in regulating interleukin-1ß (IL-1ß) induced chondrocytes apoptosis. METHODS: GSE178724, GSE79258 and GSE169077 were downloaded from Gene Expression Omibus (GEO) database and differentially expressed circRNAs, miRNAs and mRNAs were obtained by R software. Annexin V assay was used to determine cell apoptosis rate. ELISA was further performed to identify the inflammation response. Dual-luciferase reporter gene assay was conducted to examine the combination among circ-NFKB1, miR-203a-5p and ERBB4. RESULTS: Our research demonstrated that circ-NFKB1 and ERBB4 were significantly upregulated through bioinformatic analysis. MiR-203a-5p was significantly downregulated through bioinformatic analysis. Silencing of circ-NFKB1 notably inhibited the IL-1ß induced chondrocytes apoptosis and upregulated ERBB4 expression. Through prediction on bioinformatics analysis, miR-203a-5p was the target binding circ-NFKB1, and ERBB4 was the potential target of miR-203a-5p. Subsequently, these changes induced by the silencing of circ-NFKB1 were reversed upon addition of pcDNA/ERBB4. CONCLUSIONS: Silencing circ-NFKB1 could sponge miR-203a-5p to regulate ERBB4 expression and alleviate OA progression.

OBJECTIVE: To compare the clinical results of the direct anterior approach (DAA) and posterolateral approach (PLA) in total hip arthroplasty (THA) patients. METHODS: From January 2017 to September 2019, 80 patients who received primary THA in our hospital were retrospectively selected based on the propensity score matching (PSM) method. Baseline characteristics of patients who underwent the DAA and PLA were collected. Moreover, the incision length, intraoperative blood loss, operative time, length of stay, and Harris hip score were compared between patients in the two groups. The CK level was used to assess muscle damage between patients in the DAA and PLA groups. The complications of these two approaches were also evaluated at patients' 12-month follow-up evaluation. RESULTS: There was no significant difference in baseline characteristics between patients in the two groups (p > 0.05). The patients in the DAA group had a shorter incision length (9.2 ± 0.2 vs 14.7 ± 0.5, respectively; p < 0.05) and shorter length of hospital stay (9.5 ± 0.7 vs 12.9 ± 0.8, respectively, p < 0.05) than patients in the PLA group. Moreover, the DAA was associated with a decrease in intraoperative blood loss compared with the PLA (109.1 ± 12.6 vs 305.1 ± 14.1 ml, respectively, p < 0.05). However, the operation time was longer in patients in the DAA group (130.7 ± 1.7) than in patients in the PLA group (112.6 ± 1.3 min, p < 0.05). The CK level of patients in the DAA group was lower than that of patients in the PLA group (p < 0.05). The CK level at 48 h post-surgery was negatively correlated with the Harris hip scores at 6 months after THA (r = -0.538, p = 0.000). Compared with patients in the PLA group, the muscle strength of patients in the DAA group was significantly higher than that of patients in the DAA group at 4 days (p < 0.05) and 7 days (p < 0.05) after THA. The Harris hip scores of patients in the DAA group and PLA group were 81.0 ± 0.8 vs 70.8 ± 0.7 at 6 weeks, 93.4 ± 0.9 vs 86.4 ± 0.6 at 3 months, and 96.8 ± 1.1 vs 93.4 ± 0.8 at 6 months, respectively, both p < 0.05. There was no significant difference in the incidence of complications between patients in the DAA and PLA groups (p > 0.05). CONCLUSION: DAA was superior to the PLA in improving hip function after THA. Compared with the PLA, the DAA could reduce muscle damage, which is negatively correlated with hip function. Further multi-institution studies are required with longer follow-up durations, and larger patient populations are needed to provide more definitive conclusions.

OBJECTIVE: To investigate the application value of liquid crystal digital display goniometer in total hip arthroplasty. METHODS: From January 2018 to December 2019, 83 patients underwent primary total hip arthroplasty, including 28 males and 55 females, aged 42 to 81 (70.4±7.9) years. There were 63 cases of femoral neck fracture and 20 cases of avascular necrosis of femoral head. All patients used liquid crystal digital goniometer to control the anteversion of acetabular cup prosthesis during operation, and CT scanning was used to measure the anteversion of acetabular cup after operation. The two methods were compared to understand the accuracy of using liquid crystal digital goniometer. RESULTS: Postoperative CT measurement showed that the acetabular anteversion of all patients was in the safe area advocated by Lewinnek. The anteversion angle of acetabular cup measured by liquid crystal digital goniometer was 14.20(12.80 to 15.40)°, and the anteversion angle of acetabular cup measured by postoperative CT scan was 14.20 (13.40 to 15.50)°. There was no significant difference between the two (Z=-1.725, P=0.085). CONCLUSION: It is an accurate and reliable method to control the anteversion of acetabular cup with liquid crystal digital display angle instrument, which has a good auxiliary reference value.

BACKGROUND: Patellar mobilization technique during total knee replacement (TKR) has been debated, with some suggesting that lateral retraction, rather than eversion, of the patella may be beneficial. This randomized controlled trial was to investigate the effects of patellar eversion on functional outcomes in TKR. METHODS AND ANALYSIS: This single-center, prospective, randomized controlled test will be conducted in Jingjiang People's Hospital. Primary end-stage osteoarthritis patients that prepared for unilateral TKR were randomized to one of two patellar exposure techniques during the primary total knee arthroplasty: lateral retraction or eversion. The informed consent will be acquired in each patient. The primary outcome was operation time, length of hospital stay, and straight leg raising time. Second outcomes including Insall-Salvati ratio; range of motion at 1 month, 3 months, and 1 year following TKR; visual analog scale (VAS) at 1 month, 3 months; and Knee Society Score (KSS) score at 1 year following TKR. The significance level was defaulted as P < .05. RESULTS: Results will be published in relevant peer-reviewed journals. CONCLUSION: Our study aims to systematically assess the functional outcomes of patellar eversion for TKR patients, which will provide clinical guidance for TKR patients.

BACKGROUND: Total knee arthroplasty is a common surgery for end-stage of knee osteoarthritis. Proprioceptive training has become an important part in athletes training programmes in different sports. However, the effects of proprioceptive training on the recovery of total knee arthroplasty were unknown. This meta-analysis, with its comprehensive and rigorous methodology, will provide better insight into this problem. METHODS AND ANALYSIS: Electronic databases including PubMed, EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI) database, Wanfang Database and Chinese Biomedical Literature Database (CBM) were searched from its inception to October 21, 2020. We only included proprioceptive training vs placebo in patients after total knee arthroplasty and pooled results were summarized by STATA 12.0 software. Two researchers independently selected the study and assessed the quality of the included studies. The heterogeneity was measured by I2 tests (I2â<â50 indicates little heterogeneity, I2 ≥ 50 indicates high heterogeneity). Publication bias was ruled out by funnel plot and statistically assessed by Beggs test (Pâ>â.05 as no publication bias). RESULTS: Results will be published in relevant peer-reviewed journals. CONCLUSION: Our study aims to systematically present the clinical effects of proprioceptive training after total knee arthroplasty patients, which will be provide clinical guidance for total knee arthroplasty patients.

OBJECTIVE: To compare the outcomes of the direct anterior approach (DAA) with the lateral approach (LA) for total hip arthroplasty (THA) patients. METHODS: Three English databases, PubMed, Embase, and the Cochrane Library, were searched for randomized controlled trials (RCTs) comparing the DAA with LA for THA. Information on the country, sample size, intervention, outcomes, and follow-up were extracted. Meta-analysis was performed using Stata 12.0. RESULTS: Five RCTs totaling 475 patients (DAA = 236, LA = 239) were included in this meta-analysis. Compared with the LA, the DAA was associated with a reduction in the VAS at 6 weeks (weighted mean difference (WMD) = - 0.41, 95% confidence interval (CI) - 0.63 to - 0.19, P = 0.000) and total blood loss for THA patients (WMD = - 45.73, 95% CI - 84.72 to - 6.02, P = 0.024). Moreover, the DAA was associated with an increase in walking velocity (WMD = 5.01, 95% CI 2.32 to 7.70, P = 0.000), stride length (WMD = 3.12, 95% CI 2.42 to 3.82, P = 0.000), and step length (WMD = 4.09, 95% CI 1.03 to 7.14, P = 0.009) compared with the LA group. There was no significant difference between groups in the Harris hip score, operation time, transfusion rate, length of hospital stay, and the occurrence of complications. CONCLUSION: Current evidence demonstrated a trend showing that the DAA had a better effect on pain relief and blood-saving effects for THA patients. However, considering the number and sample size of the included trials, more large-scale RCTs with high quality are needed to confirm our conclusion.

BACKGROUND: This meta-analysis aimed to evaluate the postoperative clinical outcomes and safety of the direct anterior approach (DAA) versus posterior approach (PA) in total hip arthroplasty (THA). METHODS: We searched PubMed, Embase, Web of Science, the Cochrane Library, and Google databases from inception to June 2018 to select studies that compared the DAA and PA for THA. Only randomized controlled trials (RCTs) were included. Outcomes included Harris hip score at 2 weeks, 6 weeks, 12 weeks, and 1 year; VAS at 24 h, 48 h, and 72 h; incision length, operation time, postoperative blood loss, length of hospital stay, and complications (intraoperative fracture, postoperative dislocation, heterotopic ossification (HO), and groin pain). RESULTS: Nine RCTs totaling 754 THAs (DAA group = 377, PA group = 377) met the criteria to be included in this meta-analysis. The present meta-analysis indicated that, compared with PA group, DAA group was associated with an increase of the Harris hip score at the 2-week and 4-week time points. No significant difference was found between DAA and PA groups of the Harris hip scores at 12 weeks, 1 year length of hospital stay (p > 0.05). DAA group was associated with a reduction of the VAS at 24 h, 48 h, and 72 h with statistical significance (p < 0.05). What is more, DAA was associated with a reduction of the incision length and postoperative blood loss (p < 0.05). There was no significant difference between the operation time and complications (intraoperative fracture, postoperative dislocation, HO, and groin pain). CONCLUSION: In THA patients, compared with PA, DAA was associated with an early functional recovery and less pain scores. What is more, DAA was associated with shorter incision length and blood loss.

Src family kinases (SFKs) are hyperactivated in acute myeloid leukemia (AML). SFKs impede the retinoic acid receptor, and SFK inhibitors enhance all-trans retinoic acid (ATRA)-mediated cellular differentiation in AML cell lines and primary blasts. To translate these findings into the clinic, we undertook a phase-I dose-escalation study of the combination of the SFK inhibitor dasatinib and ATRA in patients with high-risk myeloid neoplasms. Nine subjects were enrolled: six received 70 mg dasatinib plus 45 mg/m2 ATRA daily, and three received 100 mg dasatinib plus 45 mg/m2 ATRA daily for 28 days. Headache and QTc prolongations were the only two grade 3 adverse events observed. No significant clinical responses were observed. We conclude that the combination of 70 mg dasatinib and 45 mg/m2 ATRA daily is safe with acceptable toxicity. Our results provide the safety profile for further investigations into the clinical efficacy of this combination therapy in myeloid malignancies.
