Abstract
OBJECTIVE Olfactory disturbance is one of the main symptoms of coronavirus disease-2019 (COVID-19). Various olfactory disorders caused by viral infections are treated with nasal corticosteroids. This study aimed to evaluate the safety and efficacy of nasal corticosteroids in the treatment of olfactory disorders caused by the severe acute respiratory syndrome coronavirus 2. DATA SOURCES We searched the Web of Science, Embase, PubMed, and Cochrane Library databases for clinical trials of nasal corticosteroids for treating COVID-19 olfactory dysfunction. REVIEW METHODS We assessed the effect of nasal corticosteroids on olfactory function in COVID-19-affected individuals using a Meta-analysis of published studies, considering the number of patients who fully recovered from olfactory dysfunction, olfactory scores following treatment, and olfactory recovery time. RESULTS Seven studies involving 930 patients were analyzed. The Meta-analysis results revealed that the olfactory score of the experimental group was 1.40 points higher than that of the control group (standardized mean difference [MD]: 1.40, 95% confidence interval [95% CI]: 0.34-2.47, P < .00001). However, the differences in the outcomes of cure rate (risk ratio: 1.18, 95% CI: 0.89-1.69, P = .21) and recovery time (MD: -1.78, 95% CI: -7.36 to 3.81, P = .53) were not statistically significant. Only 1 study reported adverse effects of nasal steroid treatment, namely tension, anger, and stomach irritation. CONCLUSION Although nasal steroid therapy does not result in significant adverse effects, it proves ineffective in the treatment of COVID-19 olfactory dysfunction.

Abstract
The pathogenesis of glucocorticoid (GC)-induced osteonecrosis of the femoral head (GIONFH) is still disputed, and abnormal bone metabolism caused by GCs may be an important factor. In vitro, Cell Counting Kit-8 (CCK-8) and 5-ethynyl-2′-deoxyuridine (EdU) staining were used to evaluate cellular proliferation, and western blotting was used to investigate osteogenesis. In vivo, we used micro-computed tomography (micro-CT), H&E staining, Masson staining, and immunohistochemistry (IHC) analysis to evaluate the impact of exosomes. In addition, the mechanism by which exosomes regulate osteogenesis through the miR-365a-5p/Hippo signaling pathway was investigated using RNA sequencing (RNA-seq), luciferase reporter assays, fluorescence in situ hybridization (FISH), and western blotting. The results of western blotting verified that the relevant genes in osteogenesis, including BMP2, Sp7, and Runx2, were upregulated. RNA-seq and qPCR of the exosome and Dex-treated exosome groups showed that miR-365a-5p was upregulated in the exosome group. Furthermore, we verified that miR-365a-5p promoted osteogenesis by targeting SAV1. Additional in vivo experiments revealed that exosomes prevented GIONFH in a rat model, as shown by micro-CT scanning and histological and IHC analysis. We concluded that exosomal miR-365a-5p was effective in promoting osteogenesis and preventing the development of GIONFH via activation of the Hippo signaling pathway in rats.

Abstract
BACKGROUND The oral cavity is a complex environment in which periodontal tissue is constantly stimulated by external microorganisms and mechanical forces. Proper mechanical force helps maintain periodontal tissue homeostasis, and improper inflammatory response can break the balance. Periodontal ligament (PDL) cells play crucial roles in responding to these challenges and maintaining the homeostasis of periodontal tissue. However, the mechanisms underlying PDL cell property changes induced by inflammatory and mechanical force microenvironments are still unclear. Recent studies have shown that exosomes function as a means of cell-cell and cell-matrix communication in biological processes. METHODS Human periodontal ligament stem cells (HPDLSCs) were tested by the CCK8 assay, EdU, alizarin red, and ALP staining to evaluate the functions of exosomes induced by a mechanical strain. MicroRNA sequencing was used to find the discrepancy miRNA in exosomes. In addition, real-time PCR, FISH, luciferase reporter assay, and western blotting assay were used to investigate the mechanism of miR-181b-5p regulating proliferation and osteogenic differentiation through the PTEN/AKT pathway. RESULTS In this study, the exosomes secreted by MLO-Y4 cells exposed to mechanical strain (Exosome-MS) contributed to HPDLSC proliferation and osteogenic differentiation. High-throughput miRNA sequencing showed that miR181b-5p was upregulated in Exosome-MS compared to the exosomes derived from MLO-Y4 cells lacking mechanical strain. The luciferase reporter assay demonstrated that miR-181b-5p may target phosphatase tension homolog deletion (PTEN). In addition, PTEN was negatively regulated by overexpressing miR-181b-5p. Real-time PCR and western blotting assay verified that miR-181b-5p enhanced the protein kinase B (PKB, also known as AKT) activity and improved downstream factor transcription. Furthermore, miR-181b-5p effectively ameliorated the inhibition of HPDLSC proliferation and promoted HPDLSC induced by inflammation. CONCLUSIONS This study concluded that exosomes induced by mechanical strain promote HPDLSC proliferation via the miR-181b-5p/PTEN/AKT signaling pathway and promote HPDLSC osteogenic differentiation by BMP2/Runx2, suggesting a potential mechanism for maintaining periodontal homeostasis.

Abstract
Ossification of the ligamentum flavum (OLF) is characterized by a process of ectopic bone formation in the ligamentum flavum. The definitive pathophysiology of OLF still remains unclear, but the epigenetic m6A modification plays an important role in OLF. In addition, no studies have reported the function of ALKBH5 in OLF development. In this study, we investigated the function of the m6A demethylation enzyme ALKBH5 in OLF. To evaluate the function of ALKBH5, OLF tissues and normal ligamentum flavum tissues were collected. In vitro methods, including HE, IHC and western blotting assays, were used to evaluate the association of ALKBH5 with OLF. In addition, we verified the effects of ALKBH5 on osteogenesis using alizarin red and ALP staining. MeRIP q-PCR was performed to investigate the methylation level of BMP2. Moreover, the mechanism of ALKBH5-mediated regulation of the ossification of the ligamentum flavum cells through the AKT signaling pathway was also verified. The present study showed that the expression of ALKBH5 increased in OLF tissues. The overexpression of ALKBH5 increased the expression of osteogenic genes and promoted the ossification of ligamentum flavum cells. Furthermore, BMP2 was significantly enriched in the ligamentum flavum cells of the anti-m6A group compared with those of the IgG group. The overexpression of ALKBH5 led to the activation of p-AKT, and BMP2 was regulated by ALKBH5 through the AKT signaling pathway. ALKBH5 promoted the osteogenesis of the ligamentum flavum cells through BMP2 demethylation and AKT activation. ALKBH5 was shown to be an important demethylation enzyme in OLF development.

Abstract
Disuse osteoporosis (DOP) is a common complication resulting from the lack of or disuse of mechanical loading and has been unsatisfactorily treated. We hypothesized that exosomes derived from human umbilical cord mesenchymal stem cells (HUCMSCs) could reduce bone marrow mesenchymal stem cell (BMSC) apoptosis in rat DOP via the miR-1263/Mob1/Hippo signaling pathway. To evaluate the function of exosomes derived from HUCMSCs (HUCMSC-Exos) in DOP, hind limb unloading (HLU)-induced DOP rat models were prepared. In vitro, the proliferation of BMSCs were evaluated using CCK-8 assays. Further, the apoptosis of BMSCs were evaluated using annexin V-FITC assay and Western blots. In vivo, the protective effects of HUCMSC-Exos were evaluated using HE staining and microCT analysis. The underlying molecular mechanism of exosome action on BMSC apoptosis through the miR-1263/Mob1/Hippo pathway was also investigated by high-throughput RNA sequencing, luciferase reporter assays, RNA-pull down assays and Western blots. The RNA-seq and q-PCR results showed that the level of miR-1263 was most abundant among differentially expressed microRNAs. Exosomal miR-1263 could bind to the 3'untranslated region (3' UTR) of Mob1 and exert its function by directly targeting Mob1 in recipient cells. The inhibition of Mob1 could activate YAP expression. Hippo inhibition reversed the in vitro HLU-induced apoptotic effect on BMSCs. The microCT and HE staining results indicated that HUCMSC-Exos ameliorated DOP in vivo. Exosomes derived from HUCMSCs are effective at inhibiting BMSC apoptosis and preventing rat DOP. This mechanism is mediated by the miR-1263/Mob1/Hippo signaling pathway.

Abstract
Purpose: Glucocorticoid-induced osteonecrosis of the femoral head (GIONFH) is a common disease after long-term or high-dose glucocorticoid use. The pathogenesis of GIONFH is still controversial, and abnormal bone metabolism caused by glucocorticoids may be one of the important factors. Exosomes, owing to their positive effect on bone repair, show promising therapeutic effects on bone-related diseases. In this study, we hypothesised that exosomes reduce osteocyte apoptosis in rat GIONFH via the miR-21-PTEN-AKT signalling pathway. Methods: To evaluate the effects of exosomes in GIONFH, a dexamethasone-treated or exosome-treated in vitro cell model and a methylprednisolone-treated in vivo rat model were set up. In vitro, a CCK-8 assay and 5-ethynyl-2'-deoxyuridine staining were performed to evaluate the proliferation of osteocytes. Further, a terminal deoxynucleotidyl transferase dUTP nick end labelling (TUNEL) assay, annexin V-fluorescein isothiocyanate-propidium iodide staining, and western blotting were conducted to evaluate the apoptosis of osteocytes. In vivo, we used micro-computed tomography and histological and immunohistochemical analyses to assess the effects of exosomes. Moreover, the mechanism of exosome action on osteocyte apoptosis through the miR-21-PTEN-AKT pathway was investigated by high-throughput RNA sequencing, fluorescence in situ hybridisation, luciferase reporter assays, and western blotting. Results: High-throughput RNA sequencing results showed that the AKT signalling pathway was up-regulated in the exosome group. Quantitative PCR and western blotting confirmed that the relative expression of genes in the AKT pathway was up-regulated. Western blotting revealed that AKT activated by exosomes inhibited osteocyte apoptosis. RNA fluorescence in situ hybridisation and luciferase reporter assays were performed to confirm the interaction between miR-21 and PTEN. According to the experiment in vivo, exosomes prevented GIONFH in a rat model as evidenced by micro-computed tomography scanning and histological and immunohistochemical analyses. Conclusions: Exosomes are effective at inhibiting osteocyte apoptosis (in MLO-Y4 cells) and at preventing rat GIONFH. These beneficial effects are mediated by the miR-21-PTEN-AKT signalling pathway.

Abstract
PURPOSE large doses of glucocorticoids (GCs) are the most common cause of glucocorticoid-induced osteonecrosis of femoral head (GIONFH). Although awareness of GIONFH among patients with GCs history has increased over recent years, several studies indicate that its mechanism remains unclear. METHODS To evaluate the function of circUSP45 in GIONFH, femoral heads in GIONFH patients or femoral heads in fracture patients were collected. In vitro, RT-PCR, FISH, RNA pull down and Western blotting assay were used to evaluate the function of circUSP45. In addition, we also verified the effects of circUSP45 on osteogenesis using alizarin red staining. In vivo, we used HE staining and microCT analysis to evaluate the bone mass. Moreover, the mechanism of circUSP45 regulating osteogenesis through the miR-127-5p/PTEN/AKT pathway was also investigated. RESULTS The results showed that expression of circUSP45 increased in GIONFH patients. The overexpression of circUSP45 decreases osteogenic gene expression and inhibits the proliferation of BMSCs. Furthermore, circUSP45 was located mainly in the cytoplasm and directly interacted with miR-127-5p. MiR-127-5p acts with its targets PTEN to regulate the osteogenesis. MicroCT and HE staining verify the function of circUSP45 in GIONFH rat model. CONCLUSION CircUSP45 decreases osteogenesis in bone GIONFH by sponging miR-127-5p through PTEN/AKT signal pathway.

Abstract
BACKGROUND Total knee arthroplasty (TKA) is accompanied by moderate-to-severe postoperative pain. Postoperative pain will hamper functional recovery and lower patients' satisfaction with surgery. Recently, periarticular local infiltration analgesia (LIA) has been widely used in TKA. However, there is no definite answer as to the efficacy and safety of LIA compared with femoral nerve block (FNB). METHOD Randomized controlled trials about relevant studies were searched from PubMed (1996 to July 2017), Embase (1980 to July 2017), and Cochrane Library (CENTRAL, July 2017). Ten studies which compared LIA with FNB methods were included in our meta-analysis. RESULTS Ten studies containing 950 patients met the inclusion criteria. Our pooled data indicated that LIA was as effective as the FNB in terms of visual analog scale score for pain at 24 hours (P = .52), 48 hours (P = .36), and 72 hours (P = .27), and total morphine consumption (P = .27), range of motion (P = .45), knee society score (P = .51), complications (P = .81), and length of hospital stay (P = .75). CONCLUSIONS Our current meta-analysis results demonstrated that there were no differences in efficacy between the FNB and LIA method.

Abstract
Intertrochanteric fractures are common injuries in the elderly. Conventional intramedullary nails including Gamma 3 locking nail and proximal femoral nail antirotation (PFNA) were designed for unstable intertrochanteric fractures. The InterTan (IT) nail system, introduced in 2005, has been reported superior biomechanical and clinical outcomes compared with 1-screw nailing system. However, some recent studies have reported that IT did not improve functional recovery in patients with intertrochanteric fractures. Randomized controlled trials (RCTs) or prospective cohort studies were included in our meta-analysis. We used the PRISMA guidelines and Cochrane Handbook to evaluate the quality of included studies to ensure that the pooled data of our meta-analysis were reliable and veritable. Our pooled data analysis demonstrated that IT was as effective as the control group in terms of Harris Hip Score (HHS), blood loss, total complications, union time, length of hospital stay, revision rate, and fluoroscopy time. IT shows less implant cut-out rate and femoral fractures when compared with control groups.

Abstract
BACKGROUND Pain management after spinal surgery has been studied for years. Gabapentin is a third-generation antiepileptic drug that selectively affects the nociceptive process and has been used for pain relief after surgery. However, the relationship between gabapentin and postoperative pain in spinal surgery is still controversial. OBJECTIVE To assess the efficacy of the pre-emptive use of gabapentin in spinal surgery. STUDY DESIGN A meta-analysis of randomized controlled studies. SETTING The MEDLINE, EMBASE, ClinicalTrials.gov, and Web of Science databases were systematically searched. METHODS This meta-analysis of randomized controlled trials (RCTs) was performed to compare the use of gabapentin with placebo in spinal surgery regarding to the following: the mean difference (MD) of postoperative opioid requirements, the changes of visual analog scale (VAS) scores in 2 groups, and the incidence rate of adverse effects. An electronic-based search of all related literatures was conducted, and only RCTs for spinal surgery were included. The MD of postoperative opioid requirements and VAS scores and the relative risk (RR) of the incidence rate of adverse effects in the gabapentin group versus the placebo group were extracted throughout the study. RESULTS Ten trials, involving 827 patients, met the inclusion criteria and were included in this meta-analysis. The total morphine consumption was significantly lower over the first 24 hours postoperatively in the gabapentin group (P < 0.05). The VAS scores at 2, 4, 6, 12, and 24 hours were less in the gabapentin group (P < 0.05). The incidence rate of vomiting, pruritus, and urinary retention was significantly less in the gabapentin groups (RR = 0.53, 95% CI 0.32-0.86, P < 0.05; RR = 0.38, 95% CI 0.22-0.66, P < 0.05; RR = 0.57, 95% CI 0.34-0.98, P < 0.05, respectively). LIMITATIONS All of the studies we screened were published online except for unpublished articles. Only 10 RCTs met our inclusion criteria, so the sample size was still relatively small. CONCLUSION This meta-analysis suggests that the administration of gabapentin is effective in reducing postoperative opioid consumption, VAS scores, and some side effects after spinal surgery. KEY WORDS Gabapentin, analgesia, spinal surgery, meta-analysis, randomized controlled trials, visual analog scale score, side effect.

Abstract
Background Total knee arthroplasty (TKA) is gradually regarded as an effective choice for end-stage osteoarthritis or rheumatic arthritis. In the past, the management of tranexamic acid (TXA) using intravenous injection or topical application has been extensively researched. However, several studies have reported that oral TXA has an effect on blood loss. Therefore, a meta-analysis should be performed to determine whether oral TXA helps to prevent blood loss. Methods Randomized controlled trials or retrospective cohort studies about relevant studies were searched in PubMed (1996–April 2017), Embase (1980–April 2017), and the Cochrane Library (CENTRAL, April 2017). Six studies that compared oral TXA to non-TXA were included in our meta-analysis. Meta-analyses (PRISMA) guidelines, the Cochrane Handbook, and the Jadad scale were used to evaluate the included studies and the results to ensure that the meta-analysis was viable. Results In accordance with inclusion and exclusion, six studies with 2553 patients (oral TXA = 1386, without TXA = 1167) were eligible and accepted into this meta-analysis. Pooled data indicated that the oral TXA group was effective compared to the without TXA group in terms of hemoglobin (Hb) drop (P < 0.05), blood loss at 24 h (P < 0.05), total blood loss (P < 0.05), and the transfusion rate (P < 0.05). No significant differences were found in the length of hospital stay (P = 0.96) and complications (P = 0.39). Conclusion Compared to the non-TXA group, the oral TXA group showed effects of blood sparing. Considering the cost and effectiveness, oral TXA is useful for TKA.

Abstract
The mechanism behind osteonecrosis of the femoral head (ONFH) remains unclear. The aim of this study was to explore the pathogenesis of ONFH from a biomechanical standpoint to provide a theoretical basis for improved treatments. We compared the bone structure of fractured femoral heads with that of necrotic femoral heads by Micro-CT scanning and histological evaluation. In addition, we compared the biomechanical properties of each zone in fractured femoral heads with those in necrotic femoral heads by using biomechanical tests. Compared with fractured femoral heads, bone microarchitecture and bone morphometry in necrotic zone and sclerotic zone of necrotic femoral heads have altered markedly. In addition, the biomechanical properties of the necrotic zone in femoral heads weaken markedly, while those of the sclerotic zone strengthen. We hypothesize that discordance between bone structure and function of the femoral head may be involved in the pathogenesis of ONFH and that more attention should be paid to the prevention and treatment of such discordance.

Abstract
BACKGROUND Pain management after total knee arthroplasty (TKA) varies and has been investigated for years. Pregabalin as an anticonvulsant agent that selectively affects the nociceptive process has been used for pain relief after operation. This meta-analysis was conducted to examine the evidence of pregabalin in TKA. METHODS Systematic searches of all related literatures were conducted using the following databases: MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials. Only randomized-controlled trials (RCTs) for TKA were included. The postoperative narcotic requirements, visual analog scale scores, knee flexion range, and relative risk of incidence rate of adverse effects in the pregabalin group versus placebo group were extracted throughout the study. RESULTS Seven placebo-controlled RCTs met the inclusion criteria. The use of pregabalin significantly decrease the postoperative total morphine consumption (P < .05) and increase the passive knee flexion range (P < .05). Compared with the control group, the incidence of some side effects (nausea, vomiting, pruritus, and constipation) was less in the pregabalin group (P < .05). CONCLUSIONS The administration of pregabalin is not only efficacious in the reduction of narcotic requirements and incidence of some adverse effect, but also workable for the improvement of passive knee flexion range after TKA.

Abstract
BACKGROUND Total knee arthroplasty (TKA) is gradually emerging as the treatment of choice for end-stage osteoarthritis. In the past, the method of liposomal bupivacaine by periarticular injection (PAI) showed better effects on pain reduction and opioid consumption after surgery. However, some recent studies have reported that liposomal bupivacaine by PAI did not improve pain control and functional recovery in patients undergoing TKA. Therefore, this meta-analysis was conducted to determine whether liposomal bupivacaine provides better pain relief and functional recovery after TKA. METHODS Web of Science, PubMed, Embase, and the Cochrane Library were comprehensively searched. Randomized controlled trials, controlled clinical trials, and cohort studies were included in our meta-analysis. Eleven studies that compared liposomal bupivacaine using the PAI technique with the conventional PAI method were included in our meta-analysis. The preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines and Cochrane Handbook were applied to assess the quality of the results published in all included studies to ensure that the results of our meta-analysis were reliable and veritable. RESULTS Our pooled data analysis demonstrated that liposomal bupivacaine was as effective as the control group in terms of visual analog scale score at 24 hours (P = .46), 48 hours (P = .43), 72 hours (P = .21), total amount of opioid consumption (P = .25), range of motion (P = .28), length of hospital stay (P = .53), postoperative nausea (P = .34), and ambulation distance (P = .07). CONCLUSION Compared with the conventional PAI method, liposomal bupivacaine shows similar pain control and functional recovery after TKA. Considering the cost for pain control, liposomal bupivacaine is not worthy of being recommended as a long-acting alternative analgesic agent using the PAI method.

Abstract
Steroid-associated osteonecrosis (SAON) is one of the common complications of clinical glucocorticoid (GC) administration, with osteocyte apoptosis appearing as the primary histopathological lesion. However, the precise mechanism underlying SAON remains unknown. Epigenetic modification may be a major cause of SAON. Recently, cumulative research revealed that Ten-Eleven Translocation (TET) proteins can catalyze the conversion of 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC) and then alter the epigenetic state of DNA. Here, we report that TET3-5hmC was upregulated in the femoral head tissues of SAON patients and MLO-Y4 cells with dexamethasone (Dex) treatment. Knockdown of TET3 in MLO-Y4 cells decreased 5hmC enrichment and rescued Dex-induced apoptosis. Meanwhile, the local intramedullary injection of TET3 siRNA in Sprague-Dawley rats abrogated GC-induced osteocyte apoptosis, histopathological changes, abnormal MRI signals, and bone microstructure declines in the femoral head in vivo. Moreover, a hydroxymethylated DNA immunoprecipitation (hMeDIP)-chip analysis of Dex-treated osteocytes revealed 456 different 5hmC-enriched genes. The Akt pathway was found to mediate the functional effect of Dex-induced dynamic 5hmC change; this was further verified in clinical samples. The loss of TET3 in MLO-Y4 cells abrogated Dex-induced Akt signaling pathway inhibition. Therefore, our data for the first time identify the effect of TET3-5hmC on the Akt pathway and the necessity of this signaling cascade in SAON, identifying a new potential therapeutic target. © 2016 American Society for Bone and Mineral Research.
