Abstract
Intrathecal delivery of autologous culture-expanded adipose tissue-derived mesenchymal stem cells (AD-MSC) could be utilized to treat traumatic spinal cord injury (SCI). This Phase I trial (ClinicalTrials.gov: NCT03308565) included 10 patients with American Spinal Injury Association Impairment Scale (AIS) grade A or B at the time of injury. The study's primary outcome was the safety profile, as captured by the nature and frequency of adverse events. Secondary outcomes included changes in sensory and motor scores, imaging, cerebrospinal fluid markers, and somatosensory evoked potentials. The manufacturing and delivery of the regimen were successful for all patients. The most commonly reported adverse events were headache and musculoskeletal pain, observed in 8 patients. No serious AEs were observed. At final follow-up, seven patients demonstrated improvement in AIS grade from the time of injection. In conclusion, the study met the primary endpoint, demonstrating that AD-MSC harvesting and administration were well-tolerated in patients with traumatic SCI.

Abstract
Objective: To investigate the clinical efficacy and safety of ferric derisomaltose injection versus iron sucrose injection in the treatment of iron deficiency anemia (IDA) . Methods: A total of 120 patients with iron deficiency anemia admitted from June 2021 to March 2023 were given intravenous iron supplementation with ferric derisomaltose to assess the efficacy and safety of hemoglobin (HGB) elevation before and after treatment. Simultaneously, the clinical effects of iron supplementation with iron sucrose were compared to those of inpatient patients during the same period. Results: Baseline values were comparable in both groups. Within 12 weeks of treatment, the elevated HGB level in the ferric derisomaltose group was higher than that of the iron sucrose group, with a statistical difference at all time points, and the proportion of HGB increased over 20 g/L in the patients treated for 4 weeks was higher (98.7%, 75.9% ). During the treatment with ferric derisomaltose and iron sucrose, the proportion of mild adverse reactions in the ferric derisomaltose group was slightly lower than that of the iron sucrose group, and neither group experienced any serious adverse reactions. The patients responded well to the infusion treatment, with no reports of pain or pigmentation at the injection site. Conclusion: The treatment of IDA patients with ferric derisomaltose has a satisfactory curative effect, with the advantages of rapidity, accuracy, and safety. Therefore, it is worthy of widespread clinical use.

Abstract
Objective: This study aimed to investigate the role and clinical significance of MUC4 gene mutations in thrombotic events in patients with classic paroxysmal nocturnal hemoglobinuria (PNH) patients. Methods: A retrospective analysis was conducted on the clinical data and gene sequencing results of 45 patients with classic PNH admitted to the Department of Hematology, Tianjin Medical University General Hospital, from June 2018 to February 2022. MUC4 gene mutations in patients with classic PNH were summarized, and the risk factors for thrombotic events in these patients were analyzed. Additionally, the effects of MUC4 gene mutations on the cumulative incidence and survival of thrombotic events in patients with classic PNH were determined. Results: The detection rate of MUC4 gene mutations in patients with classic PNH who experienced thrombotic events (thrombotic group) was 68.8% (11/16), which was significantly higher than that in the non-thrombotic group [10.3% (3/29) ] (P<0.001). All mutations occurred in exon 2. MUC4 mutation (OR=20.815, P=0.010) was identified as an independent risk factor for thrombotic events in patients with classic PNH. The cumulative incidence of thrombotic events was 78.6% (11/14) in the MUC4 gene mutation group (mutation group) and 16.1% (5/31) in the non-mutation group, showing a statistically significant difference between the two groups (P<0.001). Survival analysis showed a lower overall survival (OS) rate in the thrombotic group compared with that in the non-thrombotic group [ (34.4±25.2) % vs. (62.7±19.3) % ] (P=0.045). The OS rate of patients was (41.7±29.9) % in the mutation group and (59.1±18.3) % in the non-mutation group (P=0.487) . Conclusion: MUC4 gene mutations are associated with an increased incidence of thrombotic events in classic PNH patients, highlighting their role as independent risk factors for thrombosis in this population. These mutations can be considered a novel predictive factor that aids in evaluating the risk of thrombosis in patients with classic PNH.

Abstract
Objective: To examine the clinical effect of auxiliary liver transplantation with ultra-small volume graft in the treatment of portal hypertension. Methods: Twelve cases of portal hypertension treated by auxiliary liver transplantation with small volume graft at Liver Transplantation Center,Beijing Friendship Hospital, Capital Medical University between December 2014 and March 2022 were studied retrospectively. There were 8 males and 4 females,aged 14 to 66 years. Model for end-stage liver disease scores were 1 to 15 points and Child scores were 6 to 11 points. The grafts was derived from living donors in 9 cases,from split cadaveric donors in 2 cases,from whole cadaveric liver of child in 1 case. The graft recipient body weight ratios of 3 cadaveric donor livers were 0.79% to 0.90%, and of 9 living donor livers were 0.31% to 0.55%.In these cases, ultra-small volume grafts were implanted. The survivals of patient and graft, complications, portal vein blood flow of residual liver and graft, abdominal drainage and biochemical indexes of liver function were observed. Results: All the grafts and patients survived. Complications included outflow tract torsion in 2 cases, acute rejection in 1 case, bile leakage in 1 case, and thyroid cancer at the later stage of follow-up in 1 case, all of which were cured. The torsion of outflow tract was attributed to the change of anastomotic angle after the growth of donor liver. After the improvement of anastomotic method, the complication did not recur in the later stage. There was no complication of portal hypertension. The measurement of ultrasonic portal vein blood flow velocity showed that the blood flow of residual liver decreased significantly in the early stage after operation, and maintained a very low blood flow velocity or occlusion in the long term after operation, and the blood flow of transplanted liver was stable. Conclusions: Auxiliary liver transplantation can implant ultra-small donor liver through compensation of residual liver. This method may promote the development of living donor left lobe donation and split liver transplantation. However, the auxiliary liver transplantation is complex, and it is difficult to control the complications. Therefore, this method is currently limited to centers that are skilled in living related liver transplantation and that have complete ability to monitor and deal with complications.

Abstract
Back pain with radicular symptoms is associated with detrimental physical and emotional functioning and economic burden. Conservative treatments including physical, pharmacologic and injection therapy may not provide clinically significant or long-standing relief. Regenerative medicine research including Platelet rich plasma (PRP), Platelet lysate (PL) or Plasma rich in growth factors (PRGF) continues to develop, however evidence appraisal for treatment of radicular pain remains lacking. Thus, we performed a systematic review to evaluate the effectiveness of epidural steroid injections containing PRP or related products to treat radicular pain. Embase, PubMed/MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL), and Google Scholar databases were queried. Twelve studies were included in qualitative analysis, consisting of three randomized controlled trials and nine observational studies. The primary outcome was pain intensity, and secondary outcomes included functional improvement, anatomical changes on advanced imaging, and adverse events. All studies identified improved pain intensity and functional outcomes after epidural injection of PRP, PRGF and/or PL. Similar or longer lasting pain relief was noted in the PRP cohort compared to the cohort receiving epidural steroid injections with effects lasting up to 12-24 months. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) analysis revealed a very-low certainty of evidence due to risk of bias, indirectness, and imprecision.

Abstract
MSC (a.k.a. mesenchymal stem cell or medicinal signaling cell) cell therapies show promise in decreasing mortality in acute respiratory distress syndrome (ARDS) and suggest benefits in treatment of COVID-19-related ARDS. We performed a meta-analysis of published trials assessing the efficacy and adverse events (AE) rates of MSC cell therapy in individuals hospitalized for COVID-19. Systematic searches were performed in multiple databases through November 3, 2021. Reports in all languages, including randomized clinical trials (RCTs), non-randomized interventional trials, and uncontrolled trials, were included. Random effects model was used to pool outcomes from RCTs and non-randomized interventional trials. Outcome measures included all-cause mortality, serious adverse events (SAEs), AEs, pulmonary function, laboratory, and imaging findings. A total of 736 patients were identified from 34 studies, which included 5 RCTs (n = 235), 7 non-randomized interventional trials (n = 370), and 22 uncontrolled comparative trials (n = 131). Patients aged on average 59.4 years and 32.2% were women. When compared with the control group, MSC cell therapy was associated with a reduction in all-cause mortality (RR = 0.54, 95% CI: 0.35-0.85, I 2 = 0.0%), reduction in SAEs (IRR = 0.36, 95% CI: 0.14-0.90, I 2 = 0.0%) and no significant difference in AE rate. A sub-group with pulmonary function studies suggested improvement in patients receiving MSC. These findings support the potential for MSC cell therapy to decrease all-cause mortality, reduce SAEs, and improve pulmonary function compared with conventional care. Large-scale double-blinded, well-powered RCTs should be conducted to further explore these results.

Abstract
BACKGROUND CONTEXT There are limited treatments for discogenic low back pain. Intradiscal injections of biologic agents such as platelet-rich plasma (PRP) or stem cells (SC) are theorized to have regenerative properties and have gained increasing interest as a possible treatment, but the evidence supporting their use in clinical practice is not yet well-defined. PURPOSE Determine the effectiveness of intradiscal biologics for treating discogenic low back pain. STUDY DESIGN PRISMA-compliant systematic review. PATIENT SAMPLE Patients with discogenic low back pain confirmed by provocation discography or clinical and imaging findings consistent with discogenic pain. OUTCOME MEASURES The primary outcome was the proportion of individuals with ≥50% pain relief after intradiscal biologic injection at 6 months. Secondary outcomes included ≥2-point pain score reduction on NRS; patient satisfaction; functional improvement; decreased use of other health care, including analgesics and surgery; and structural disc changes on MRI. METHODS Comprehensive literature search performed in 2018 and updated in 2020. Interventions included were biologic therapies including mesenchymal stem cells, platelet rich plasma, microfragmented fat, amniotic membrane-based injectates, and autologous conditioned serum. Any other treatment (sham or active) was considered for comparative studies. Studies were independently reviewed. RESULTS The literature search yielded 3,063 results, 37 studies were identified for full-text review, and 12 met established inclusion criteria for review. The quality of evidence on effectiveness of intradiscal biologics was very low. A single randomized controlled trial evaluating platelet-rich plasma reported positive outcomes but had significant methodological flaws. A single trial that evaluated mesenchymal stem cells was negative. Success rates for platelet-rich plasma injectate in aggregate were 54.8% (95% Confidence Interval: 40%-70%). For mesenchymal stem cells, the aggregate success rate at six months was 53.5% (95% Confidence Interval: 38.6%-68.4%), though using worst-case analysis this decreased to 40.7% (95% Confidence Interval: 28.1%-53.2%). Similarly, ≥30% functional improvement was achieved in 74.3% (95% Confidence Interval: 59.8%-88.7%) at six months but using worst-case analysis, this decreased to 44.1% (95% Confidence Interval: 28.1%-53.2%). CONCLUSION Limited observational data support the use of intradiscal biologic agents for the treatment of discogenic low back pain. According to the Grades of Recommendation, Assessment, Development and Evaluation System, the evidence supporting use of intradiscal mesenchymal stem cells and platelet-rich plasma is very low quality.

Abstract
BACKGROUND During the last decades, platelet-rich plasma has been studied for the treatment of multiple chronic pain conditions, in addition to being employed in the enhancement of healing after tissue injury. OBJECTIVE To establish a framework for future research regarding the utilization of platelet-rich plasma in the treatment of chronic tissue injuries. METHODS Preclinical and clinical studies from 2000-2020 relevant to applications of platelet-rich plasma for the treatment of chronic pain conditions were extracted from PubMed and Medline databases. The studies were analyzed on the basis of the study population, type of intervention, method of platelet-rich plasma preparation, the number of treatments administered, the timeframe of injections, and clinical outcomes. RESULTS Although several preclinical studies and double-blind, randomized trials have shown promising results in the application of platelet-rich plasma for the treatment of multiple chronic pain conditions, various studies have also reported controversial results. Additionally, the methods employed for obtaining the platelet-rich plasma have not been standardized between studies, resulting in different concentrations of blood components between the preparations utilized. Moreover, differences between studies were also found regarding the number of injections administered per treatment. CONCLUSIONS Future research addressing the utilization of platelet-rich plasma in the treatment of chronic pain conditions should focus on shedding light on the following major questions: a) Is there a dose-effect relation between the platelet count and the clinical efficacy of the preparation?; b) What pathology determinants should be considered when selecting between leukocyte-enriched and leukocyte-depleted concentrates?; c) What is the role of platelet activation methods on the clinical efficacy of platelet-rich plasma?; d) Is there an optimal number of injections and time frame for application of multiple injection treatment cycles?; e) Does the addition of local anesthetics affect the clinical efficacy of platelet-rich plasma?; and f) Is there potential for future platelet-rich plasma applications for the treatment of neuropathic pain of peripheral origin?

Abstract
OBJECTIVE To analyze opioid intake interference with psychological, well-being, and functional outcomes and medication tapering in patients with fibromyalgia admitted to the Mayo Clinic Pain Rehabilitation Program (MCPRP) in Florida. PATIENTS AND METHODS A retrospective study on MCPRP outcomes was conducted. We reviewed the health records of 150 patients with fibromyalgia who participated in the program from May 1, 2014, to May 1, 2015. All patients were asked to fill out a survey at admission to and dismissal from the program. Surveys contained questions from the numeric pain score, Multidimensional Pain Inventory (perceived life control and interference of pain subscales), Center for Epidemiological Studies-Depression Scale, Pain Catastrophizing Scale, 36-Item Short-Form Health Status Survey (general health perceptions subscale), and Pain Self-Efficacy Questionnaire. A medical record review identified categories and number of medications at program admission and dismissal. Patients were divided in 2 groups: those whose concomitant medication did not include opioids at admission (no opioids group) and those whose concomitant medication included opioids at admission (opioids group). RESULTS By dismissal from the MCPRP, patients with fibromyalgia in the no opioids group had a significant (P<.05) improvement in all the self-reported scores. Medication, including opioids, were effectively tapered at a substantially higher percentage in the opioids group. CONCLUSION Benefit of the comprehensive pain rehabilitation program in patients with fibromyalgia was indicated by clinical improvements in pain severity, physical and emotional health, and functional capacity while successfully tapering medication. Opioid intake at admission may modify the program outcomes.

Abstract
Currently, large numbers of clinical trials are performed to investigate different forms of experimental therapy for patients suffering from chronic spinal cord injury (SCI). However, for the enrollment process, there are different views on how the time period between injury and interventions should be determined. Herein, we sought to evaluate the impact of time-to-enrollment in chronic SCI clinical trials. A data set comprising 957 clinical studies from clinicalTrials.gov was downloaded and analyzed focusing on the eligibility criteria for post-injury time-to-enrollment. We also aggregated individual patient data from nine clinical trials of regenerative interventions for chronic SCI selected by a systematic literature search from 1990 to 2018. Characteristics of the studies were assessed and compared by dividing into three groups based on time-to-enrollment (group 1 ≤ 12 months, group 2 = 12–23 months and group 3 ≥ 24 months). In ClinicalTrials.gov registry, 445 trials were identified for chronic SCI where 87% (385) were unrestricted in the maximum post-injury time for trial eligibility. From systematic literature search, nine studies and 156 patients (group 1 = 30, group 2 = 55 and group 3 = 71) were included. The range of time-to-enrollment was 0.5 to 321 months in those studies. We also observed various degrees of motor and sensory improvement in between three time-to-enrollment groups. Our results indicate that enrolling wide ranges of time-to-enrollment in a group may present imprecise outcomes. Clinical trial designs should consider appropriate post-injury time frames to evaluate therapeutic benefit.

Abstract
OBJECTIVE To evaluate the effectiveness and adverse events of autologous platelet-rich plasma (PRP) in individuals with lower-extremity diabetic ulcers, lower-extremity venous ulcers, and pressure ulcers. PATIENTS AND METHODS We searched multiple databases from database inception to June 11, 2020, for randomized controlled trials and observational studies that compared PRP to any other wound care without PRP in adults with lower-extremity diabetic ulcers, lower-extremity venous ulcers, and pressure ulcers. RESULTS We included 20 randomized controlled trials and five observational studies. Compared with management without PRP, PRP therapy significantly increased complete wound closure in lower-extremity diabetic ulcers (relative risk, 1.20; 95% CI, 1.09 to 1.32, moderate strength of evidence [SOE]), shortened time to complete wound closure, and reduced wound area and depth (low SOE). No significant changes were found in terms of wound infection, amputation, wound recurrence, or hospitalization. In patients with lower-extremity venous ulcers or pressure ulcers, the SOE was insufficient to estimate an effect on critical outcomes, such as complete wound closure or time to complete wound closure. There was no statistically significant difference in adverse events. CONCLUSION Autologous PRP may increase complete wound closure, shorten healing time, and reduce wound size in individuals with lower-extremity diabetic ulcers. The evidence is insufficient to estimate an effect on wound healing in individuals with lower-extremity venous ulcers or pressure ulcers. TRIAL REGISTRATION PROSPERO Identifier: CRD42020172817.

Abstract
Bone marrow aspiration (BMA) through the iliac crest is potentially unsafe due to the vicinity of neurovascular structures in the greater sciatic notch. Our objective was to investigate the safety of a recently described BMA technique, specifically a trajectory from the posterior superior iliac spine (PSIS) to the anterior inferior iliac spine (AIIS). We conducted a chart review of 260 patients, analyzing three-dimensional reconstructed computed tomography images of the pelvis and sacrum to validate that this new approach offers a wide safety margin from the greater sciatic notch. Analysis of three-dimensional computed tomography scans demonstrated that the PSIS to AIIS trajectory never crossed the greater sciatic notch. The trajectory was noted to be at least one cm away from the greater sciatic notch in all measurements. The new trajectory entered the PSIS at 25.29 ± 4.34° (left side) and 24.93 ± 4.15° (right side) cephalad from the transverse plane, and 24.58 ± 4.99° (left side) and 24.56 ± 4.67° (right side) lateral from the mid-sagittal plane. The area of bone marrow encountered with the new approach was approximately 22.5 cm2. Utilizing the same CT scans, the trajectory from the traditional approach crossed the greater sciatic notch in all scans, highlighting the potential for violating the greater sciatic notch boundary and damaging important neurovascular structures. Statistically significant sex-related differences were identified in needle trajectory angles for both approaches. We conclude that based on this three-dimensional computed tomography study, a trajectory from the PSIS to the AIIS for BMA may offer a wide safety margin from the greater sciatic notch.

Abstract
OBJECTIVE To evaluate the association between hypovitaminosis D and outcomes of symptom severity, mood disorders, fatigue, and quality of life in fibromyalgia (FM) patients. METHODS Five hundred ninety-three FM patients were surveyed from May 2012 to November 2013. Patients with serum vitamin D <25 ng/mL were considered to have hypovitaminosis D. The primary outcome was FM symptom severity (FIQ-R questionnaire). Secondary outcomes included quality of life (SF-36), fatigue (MFI-20), anxiety (GAD-7), and depression (PHQ-9). Independent t tests and chi-square tests were performed for continuous and categorical variables, respectively. Regression analysis was performed adjusting for age, gender, body mass index, ethnicity, and season. A post hoc analysis examined for correlation between outcomes and serum vitamin D (ng/mL) as a continuous variable. RESULTS One hundred twenty-two patients (20.6%) had hypovitaminosis D. In our adjusted regression analysis, the total FIQ-R score in patients with hypovitaminosis D was higher compared with control patients with adequate serum vitamin D (57.85 ± 18.09 vs 62.79 ± 18.10, P = 0.04). Adjusted regression analysis revealed higher total GAD-7 (P = 0.01) and higher total PHQ-9 scores (P = 0.04) in patients with hypovitaminosis D compared with control patients. There were no differences based on severity of depression or anxiety. No differences in fatigue or quality of life were identified. Unadjusted post hoc analysis revealed that as serum vitamin D increased, there was an association with lower total FIQ-R (β coefficient = -0.11, P = 0.02) and lower SF-36 subscale scores of role-physical (β coefficient = -0.10, P = 0.03). Adjusted post hoc analysis revealed no significant associations. CONCLUSIONS Hypovitaminosis D may be a risk factor for worse symptom severity, anxiety, and depression in FM patients.

Abstract
OBJECTIVE The purpose of this study was to explore the effects of Kruppel like factors 11 (KLF11) on oxidative stress, apoptosis, and endoplasmic reticulum stress (ERS) in osteoarthritis (OA) and its mechanism. PATIENTS AND METHODS Human articular cartilage tissue was used to study the correlation between KLF11 and OA. Furthermore, human chondrocytes were used to explore the effects of KLF11 on oxidative stress, apoptosis, and ERS in chondrocytes by overexpressing KLF11 and using the OA inducer IL-1β. The p38MAPK signaling pathway agonist P79350 was used to study the effect of KLF11 on the p38 MAPK signaling pathway. RESULTS Articular cartilage tissue in OA patients and IL-1β-induced chondrocytes expressed higher KLF11. Overexpression of KLF11 significantly reduced oxidative stress levels, apoptosis levels, and activity of ERS-related pathways in chondrocytes. Moreover, P79350 attenuated the protective effect of KLF11 on chondrocytes by activating the p38MAPK signaling pathway. CONCLUSIONS KLF11 protects against OA by inhibiting oxidative stress, apoptosis, and ERS in chondrocytes by inhibiting p38MAPK signaling pathway.

Abstract
Mesenchymal stromal cells (MSC) have immune regulatory and tissue regenerative properties. MSCs are being studied as a therapy option for many inflammatory and immune disorders and are approved to treat acute graft-versus-host disease (GvHD). The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic and associated coronavirus infectious disease-19 (COVID-19) has claimed many lives. Innovative therapies are needed. Preliminary data using MSCs in the setting of acute respiratory distress syndrome (ARDS) in COVID-19 are emerging. We review mechanisms of action of MSCs in inflammatory and immune conditions and discuss a potential role in persons with COVID-19.

Abstract
Microglia play an important role in the central sensitization and chronic pain. However, a direct connection between microglial function and pain development in vivo remains incompletely understood. To address this issue, we applied chemogenetic approach by using CX3CR1creER/+:R26LSL-hM4Di/+ transgenic mice to enable expression of inhibitory Designer Receptors Exclusively Activated by Designer Drugs (Gi DREADD) in microglia. We found that microglial Gi DREADD activation inhibited spinal nerve transection (SNT)-induced microglial reactivity as well as chronic pain in both male and female mice. Gi DREADD activation downregulated the transcription factor interferon regulatory factor 8 (IRF8) and its downstream target pro-inflammatory cytokine interleukin 1 beta (IL-1β). Using in vivo spinal cord recording, we found that activation of microglial Gi DREADD attenuated synaptic transmission following SNT. Our results demonstrate that microglial Gi DREADD reduces neuroinflammation, synaptic function and neuropathic pain after SNT. Thus, chemogenetic approaches provide a potential opportunity for interrogating microglial function and neuropathic pain treatment.

Abstract
Objective To investigate sex-related differences in patients with fibromyalgia (FM) in terms of demographic characteristics and clinical features, including tender point count (TPC), mood disorders, sleep problems, FM symptom severity, fatigue, cognitive dysfunction, and quality of life (QOL). Patients and Methods We studied 668 consecutive patients with FM (606 women) from May 1, 2012, to November 30, 2013. Validated questionnaires assessed outcomes of depression (Patient Health Questionnaire-9), anxiety (Generalized Anxiety Disorder-7), sleep problems (Medical Outcomes Study Sleep Scale), FM symptom severity (Revised Fibromyalgia Impact Questionnaire), fatigue (Multidimensional Fatigue Inventory), cognitive dysfunction (Multiple Ability Self-report Questionnaire), and QOL (36-Item Short Form Health Survey). Nonparametric Mann-Whitney U and Pearson χ2 tests were used to compare continuous and categorical outcome measures, respectively, between men and women. Linear regression models were performed for all continuous dependent variables, adjusting for age, body mass index, ethnicity, marital status, and highest education level completed. P<.05 was considered statistically significant. The Benjamini-Hochberg procedure was used to adjust for multiple comparisons. Results Multiple linear regression analysis revealed a significant association of female sex and greater TPC (P<.001), lower overall FM symptom severity (lower overall Revised Fibromyalgia Impact Questionnaire score; P=.03), and higher QOL subscale score for vitality (36-Item Short Form Health Survey vitality subscale score; P=.02). After adjustment for multiple comparisons, only the association between female sex and greater TPC remained significant. There were no sex-related differences in demographic characteristics, depression, anxiety, sleep problems, FM symptom severity, cognitive dysfunction, and QOL. Conclusion A higher TPC may be associated with female sex in patients with FM. The assumption of other sex-based differences in the clinical presentation of FM was not supported in our study.

Abstract
BACKGROUND This systematic review appraises the evidence from human clinical trials comparing postoperative pain scores and opioid consumption in patients receiving intra-articular ketamine versus other modalities of analgesia after orthopedic joint procedures. METHODS Studies were identified from Embase, Scopus, and OVID Medline databases. Included studies compared patients receiving intra-articular ketamine versus other modalities of analgesia. The primary outcome of interest was postprocedural pain score and total opioid consumption, whereas secondary outcomes included time to rescue analgesic medication request, active range of motion, time to mobilization, and adverse effects. RESULTS Seventeen studies were included. Dosage of ketamine varied widely from 0.25 to 2 mg/kg. Fifteen of 17 demonstrated decreased overall pain scores and decreased total postoperative opioid consumption in patients receiving intra-articular ketamine versus control groups. Included studies generally demonstrated reduced time to mobilization and increased latency until rescue analgesic medication in the intra-articular ketamine group. CONCLUSIONS Patients who received intra-articular ketamine generally reported lower pain scores and had lower postoperative opioid consumption after orthopedic joint procedures. This suggests that the intra-articular route of ketamine delivery may be a useful analgesic modality, although future larger-scale trials should explore its pharmacokinetics, optimal dosing, safety, and cost-effectiveness.

Abstract
OBJECTIVE This study aims to explore whether the inhibitory role of metformin could inhibit LPS-induced inflammatory response in vascular smooth muscle cells (VSMCs) and its underlying mechanism. MATERIALS AND METHODS VSMCs were extracted from aorta of Sprague Dawley rats. MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay was performed to detect VSMCs viability after treatment with different concentrations of metformin. Levels of monocyte chemoattractant protein-1 (MCP-1), interleukin 6 (IL-6) and tumor necrosis factor-α (TNF-α) in VSMCs were detected by ELISA (enzyme-linked immunosorbent assay) and qRT-PCR (quantitative Real time-polymerase chain reaction). Protein and mRNA levels of toll like receptor 4 (TLR4) and peroxisome proliferators activated receptor γ (PPAR-γ) in VSMCs were detected by Western blot and qRT-PCR, respectively. Finally, VSMCs were treated with the PPAR-γ antagonist GW9662 and inflammatory indicators in cells were detected. RESULTS No significant difference in VSMCs viability was found after 0-2 mM metformin treatment or 500 μg/L LPS induction for 24 h. After 500 μg/L LPS induction in VSMCs for 24 h, levels of MCP-1, TNF-α and IL-6 were remarkably elevated. Both mRNA and protein levels of TLR4 in VSMCs were upregulated after 500 μg/L LPS induction for 24 h, which were remarkably reversed by the treatment of different concentrations of metformin. Knockdown of TLR4 remarkably inhibited LPS-induced inflammatory response in VSMCs, manifesting as decreased levels of MCP1, TNF-α and IL-6, which were further downregulated after combination treatment of TLR4 knockdown and 20 mM metformin. Furthermore, both mRNA and protein levels of PPAR-γ in VSMCs were downregulated after 500 μg/L LPS induction for 24 h, which were remarkably reversed by the treatment of different concentrations of metformin. GW9662 treatment resulted in elevated expressions of MCP-1, TNF-α and IL-6, which were reversed by metformin treatment. CONCLUSIONS Metformin can effectively inhibit the mRNA and protein expressions of IL-6, MCP-1, and TNF-α in LPS-induced VSMCs. The anti-inflammatory effects of metformin inhibit the inflammatory response through downregulating rely on the downregulation of TLR4 expression and upregulation ofng PPAR-γ activity.

Abstract
Severe cases of COVID-19 infection, often leading to death, have been associated with variants of acute respiratory distress syndrome (ARDS). Cell therapy with mesenchymal stromal cells (MSCs) is a potential treatment for COVID-19 ARDS based on preclinical and clinical studies supporting the concept that MSCs modulate the inflammatory and remodeling processes and restore alveolo-capillary barriers. The authors performed a systematic literature review and random-effects meta-analysis to determine the potential value of MSC therapy for treating COVID-19-infected patients with ARDS. Publications in all languages from 1990 to March 31, 2020 were reviewed, yielding 2691 studies, of which nine were included. MSCs were intravenously or intratracheally administered in 117 participants, who were followed for 14 days to 5 years. All MSCs were allogeneic from bone marrow, umbilical cord, menstrual blood, adipose tissue, or unreported sources. Combined mortality showed a favorable trend but did not reach statistical significance. No related serious adverse events were reported and mild adverse events resolved spontaneously. A trend was found of improved radiographic findings, pulmonary function (lung compliance, tidal volumes, PaO2 /FiO2 ratio, alveolo-capillary injury), and inflammatory biomarker levels. No comparisons were made between MSCs of different sources.

Abstract
Low back pain due to lumbar Degenerative Disc Disease (DDD) is one of the most common causes of disability and morbidity, particularly among older adults. Current research efforts in lumbar DDD management are shifting towards identifying and correcting the pathology in intervertebral discs without any external manipulation. Herein, we present a systematic review of current literature regarding regenerative treatments for lumbar DDD. An electronic search of databases including PubMed, Ovid/MEDLINE, Cochrane and Scopus was conducted for articles in all available years. Studies that investigated treatment for discogenic pain in lumbar DDD, including any type of stem cell or bone marrow concentrate as the treatment agent and studies that report both baseline and follow-up pain and Oswestry Disability Index (ODI) scores were included in the review. Changes in pain and ODI scores were calculated for 3-month, 6-month and 12-month periods. Six studies with a total of 93 patients were evaluated. Mean (SD) age of the pooled sample was 40.0(8.1) and 39.5% (32/81) of patients were female. Pain improvement was reported in 38.8% of patients at 3-month, 40.8% at 6-month and 44.1% at 12-month follow-up. Average improvement in ODI score for 3-month, 6-month and 12-month follow-ups was calculated to be 24.0, 26.5 and 25.7, respectively. Regenerative treatments are being increasingly employed across all spectrums of medicine. Review of six single arm studies revealed a potential positive impact in the preliminary results. However, these promising 'preliminary' results should not be interpreted as the definite treatment and should be validated with further prospective studies.

Abstract
Heterotopic Ossification (HO) refers to the formation of bone within soft tissue. Traumatic spinal cord injury (SCI) has been shown to be associated with development of HO. However, risk factors for HO following SCI are unknown. In light of this knowledge gap, we performed a systematic review and meta-analysis to summarize available evidence and elucidate risk factors associated with heterotopic ossification. An electronic literature search was conducted using five databases. Studies containing SCI patients, with a proportion diagnosed with HO, were included. Meta-analyses were performed to assess the association between following risk factors and development of HO: sex, type of injury, spasticity, pressure ulcer, injury level, urinary tract infection (UTI), deep vein thrombosis (DVT), number of smokers, and pneumonia. Nine studies with 2,115 patients were included. It was found that males (Odds Ratio [95% Confidence Interval]: 2.25 [1.61, 3.13]), smokers (2.88 [1.62, 5.11]), patients with complete injury (3.61 [2.29, 5.71]), pneumonia (2.86 [2.18, 3.75]), pressure ulcers (2.45 [1.89, 3.18]), UTI (3.84 [2.63, 5.62]) and spasticity (2.12 [1.67, 2.68]) had significantly higher odds of developing HO after spinal cord injury. In contrast, location of injury (Cervical vs. thoracic injury; (1.03 [0.72, 1.49]) and DVT (1.37 [0.91, 2.07]) were not associated with development of HO. Pooled results from existing literature on HO development show that several factors are significantly associated with development of HO. Given the complexity of SCI management, the results might have a positive impact on the clinical practice by leading to an effective screening aproach.

Abstract
Spinal cord injury (SCI) is a devastating condition with limited pharmacological treatment options to restore function. Regenerative approaches have recently attracted interest as an adjuvant to current standard of care. Adipose tissue-derived (AD) mesenchymal stem cells (MSCs) represent a readily accessible cell source with high proliferative capacity. The CELLTOP study, an ongoing multidisciplinary phase 1 clinical trial conducted at Mayo Clinic (ClinicalTrials.gov Identifier: NCT03308565), is investigating the safety and efficacy of intrathecal autologous AD-MSCs in patients with blunt, traumatic SCI. In this initial report, we describe the outcome of the first treated patient, a 53-year-old survivor of a surfing accident who sustained a high cervical American Spinal Injury Association Impairment Scale grade A SCI with subsequent neurologic improvement that plateaued within 6 months following injury. Although he improved to an American Spinal Injury Association grade C impairement classification, the individual continued to be wheelchair bound and severely debilitated. After study enrollment, an adipose tissue biopsy was performed and MSCs were isolated, expanded, and cryopreserved. Per protocol, the patient received an intrathecal injection of 100 million autologous AD-MSCs infused after a standard lumbar puncture at the L3-4 level 11 months after the injury. The patient tolerated the procedure well and did not experience any severe adverse events. Clinical signs of efficacy were observed at 3, 6, 12, and 18 months following the injection in both motor and sensory scores based on International Standards for Neurological Classification of Spinal Cord Injury. Thus, in this treated individual with SCI, intrathecal administration of AD-MSCs was feasible and safe and suggested meaningful signs of improved, rather than stabilized, neurologic status warranting further clinical evaluation.

Abstract
PURPOSE Adipose-derived mesenchymal stem cells (MSCs) are attractive biological agents in regenerative medicine. To optimize cell therapies, it is necessary to determine the most effective delivery method for MSCs. Therefore, we evaluated the biological properties of MSCs after exposure to various temperatures to define optimal storage conditions prior to therapeutic delivery of MSCs. DESIGN Prospective observational study. METHODS AND MATERIALS Adherent and non-adherent MSCs were incubated at multiple temperatures (i.e., 4, 23 and 37 °C) in Lactated Ringers (LR) solution lacking essential cell growth ingredients, or in culture media which is optimized for cell growth. Cells were assessed either after the temperature changes (4 h) or after recovery (24 h). Metabolic activity of MSCs, cell number and expression of representative mRNA biomarkers were evaluated to assess the biological effects of temperature. We monitored changes in mRNAs expression related to cytoprotective- or stress-related responses (e.g., FOS, JUN, ATF1, ATF4, EGR1, EGR2, MYC), proliferation (e.g., HIST2H4, CCNB2), and extracellular matrix production (ECM; e.g., COL3A1, COL1A1) by quantitative real time reverse-transcriptase polymerase chain reaction (RT-qPCR) analysis. RESULTS Our study demonstrates that storing MSCs in Lactated Ringers (LR) solution for 4 h decreases cell number and metabolic activity. The number of viable MSCs decreased significantly when cultured at physiological temperature (37 °C) and severe hypothermia (4 °C), while cells grown at ambient temperature (23 °C) exhibited the least detrimental effects. There were no appreciable biological differences in mRNA markers for proliferation or ECM deposition at any of the temperatures. However, biomarkers related to cytoprotective- or stress-responses were selectively elevated depending on temperature or media type (i.e., LR versus standard media). CONCLUSION The biological impact of nutrient-free media and temperature changes after 4 h exposure persists after a 24 h recovery period. Hence, storage temperature and media conditions should be optimized to improve effective dosing of MSCs.

Abstract
OBJECTIVE To assess the biologic effects of lidocaine on the viability, proliferation, and function of human adipose tissue-derived mesenchymal stromal/stem cells (MSCs) in vitro. METHODS Adipose-derived MSCs from three donors were exposed to lidocaine at various dilutions (2 mg/mL to 8 mg/mL) and exposure times (0.5 to 4 hours). Cell number and viability, mitochondrial activity, and real-time reverse-transcriptase quantitative polymerase chain reaction (RT-qPCR) were analyzed at 0 (immediate effects) or 24 and 48 hours (recovery effects) after treatment with lidocaine. RESULTS Trypan blue staining showed that increasing concentrations of lidocaine decreased the number of observable viable cells. 3-[4,5,dimethylthiazol-2-yl]-5-[3-carboxymethoxy-phenyl]-2-[4-sulfophenyl]-2H-tetrazolium (MTS) assays revealed a concentration- and time- dependent decline of mitochondrial activity and proliferative ability. Gene expression analysis by RT-qPCR revealed that adipose-derived MSCs exposed to lidocaine express robust levels of stress response/cytoprotective genes. However, higher concentrations of lidocaine caused a significant downregulation of these genes. No significant differences were observed in expression of extracellular matrix (ECM) markers COL1A1 and DCN except for COL3A1 (P < .05). Levels of messenger RNA (mRNA) for proliferation markers (CCNB2, HIST2H4A, P < .001) and MKI67 (P < .001) increased at 24 and 48 hours. Expression levels of several transcription factors- including SP1, PRRX1, and ATF1-were modulated in the same manner. MSC surface markers CD44 and CD105 demonstrated decreased expression immediately after treatment, but at 24 and 48 hours postexposure, the MSC markers showed no significant difference among groups. CONCLUSION Lidocaine is toxic to MSCs in a dose- and time- dependent manner. MSC exposure to high (4-8 mg/mL) concentrations of lidocaine for prolonged periods can affect their biologic functions. Although the exposure time in vivo is short, it is essential to choose safe concentrations when applying lidocaine along with MSCs to avoid compromising the viability and potency of the stem cell therapy.

Abstract
Background Lumbar spinal stenosis (LSS) is a chronic condition that causes low back pain and neurogenic claudication, often resulting in significant limitation of daily activities. In this open-label randomized controlled pilot study, we assessed the safety and feasibility of 4-week novel integrative inpatient treatments for LSS. Methods Thirty-six symptomatic LSS patients were randomly and equally allocated to one of the three groups: Mokhuri Chuna treatment 1 (MT1) group, Mokhuri Chuna treatment 2 (MT2) group, or conventional management treatment (CMT) group. MT1 patients were treated with herbal medication, Mokhuri Chuna, and acupuncture, and received daily physician consultation; MT2 patients were treated with Mokhuri Chuna and acupuncture without any herbal medication, and received daily physician consultation; and CMT patients received conventional pain management therapy that included epidural steroid injection, oral NSAID, and muscle relaxant medication, along with daily physiotherapy. The primary outcome of this pilot study was safety as measured by the type and incidence of adverse events (AEs). The secondary outcome measures included VAS score for low back pain and leg pain, Oswestry Disability Index, Oxford Claudication Score (OCS), walking capacity on a 50 m flat track and treadmill, and EuroQol-5D score. Magnetic resonance imaging was also performed up to 6 months after treatment cessation. Results Thirty-four treated patients were included in the analysis, based on the modified intention-to-treat principle. No serious AEs were observed or reported. Compared to the CMT group, the MT1 and MT2 groups did show significant improvement at 3 and 6 months in various domains, including pain (VAS score for leg and back pain) and function (OCS and treadmill walking). Conclusion These novel multimodal integrative treatments for LSS are both clinically safe and logistically feasible. Larger, adequately powered randomized controlled trials will be necessary to assess comparative efficacy and thoroughly analyze the cost-effectiveness of each treatment approach. Clinical trial registration number (CRIS) KCT0001218.

Abstract
Objective The aim of this paper is to review the available literature investigating the effect of epidural steroid injections (ESIs) on bone mineral density (BMD) and vertebral fracture risk. Study design Systematic review of current literature. Methods The sources of the data were PubMed, Embase, Cochrane, and Scopus. Papers included in the review were original research articles in peer-reviewed journals. Results A total of 7,233 patients (eight studies) with a mean age ranging between 49 and 74 years and an average follow-up between six and 60 months were studied. Steroids that were used included triamcinolone, dexamethasone, and methylprednisolone (MP), with a mean number of injections ranging from one to 14.7 and an average cumulative dose in MP equivalents between 80 and 8,130 mg. Epidural steroids were associated with significantly decreased BMD in four out of six included studies, and with increased risk of vertebral fracture in one out of two included studies. Significant reductions in BMD were associated with a cumulative MP dose of 200 mg over a one-year period and 400 mg over three years, but not in doses of less than 200 mg of MP equivalents for postmenopausal women and at least 3 g for healthy men. The risk of osteopenia and osteoporosis was lower in patients who were receiving anti-osteoporotic medication during the treatment course. Conclusions ESIs should be recommended with caution, especially in patients at risk for osteoporotic fractures, such as women of postmenopausal age. Anti-osteoporotic medication might be considered prior to ESI.

Abstract
Objective: To explore the distribution and intensity of kitchen waste treatment plant, providing scientific basis for occupational diseases prevention and treatment in that industry. Methods: 30 operating personnel in a kitchen waste disposal enterprise were selected as the research group and 16 non-operating personnel as the control group. The epidemiological survey was carried out in June 2015 and July 2016, and the results of occupational hazards and occupational health monitoring during 2015 to 2017 were analyzed. Results: The results of various occupational hazards factors during 2015 to 2017 were all in accordance with the occupational health limit, but the results of occupational health examination were abnormal. The occupational correlation could not be ruled out by the abnormality of electrical audiometry, electrocardiogram and Department of Dermatology examination. Conclusion: Workers in kitchen waste treatment plant are likely to suffer low-intensity, continuous health damage. There is occupational health risk in that industry. The accumulation of basic information and the improvement of relevant standards and methods are needed for further study.

Abstract
Objective To evaluate the association between smoking and cognitive function in patients with fibromyalgia. Patients and Methods We surveyed 668 patients with fibromyalgia from May 1, 2012 through November 30, 2013 at a major tertiary referral center. Patients were categorized by smoking status. Primary outcome of interest was cognitive function (MASQ questionnaire), and secondary outcomes included fibromyalgia symptom severity (FIQ-R questionnaire), quality of life (SF-36 questionnaire), fatigue (MFI-20 questionnaire), sleep (MOS-sleep scale), anxiety (GAD-7 questionnaire), and depression (PHQ-9 questionnaire). Independent Students' t-tests and χ2 tests were performed for continuous and categorical variables, respectively. Univariate regression analysis identified variables predictive of outcomes, adjusting for age, gender, body mass index, marital status, and educational level. Results Ninety-four (14.07%) patients self-identified as smokers. There was an association of lower education level, unmarried status, and younger age in smokers compared with nonsmokers. In the adjusted univariate regression analysis, fibromyalgia smokers reported greater perceived total cognitive dysfunction (P=.009) and greater subscale scores of perceived difficulty in language (P=.03), verbal memory (P=.003), visual-spatial memory (P=.02), and attention (P=.04) compared with nonsmokers with fibromyalgia. For secondary outcomes, smokers with fibromyalgia reported greater severity of fibromyalgia-related symptoms (P=.006), worse quality-of-life index in the mental component scale (P=.02), greater sleep problems (P=.01), and increased anxiety (P=.001) compared with nonsmokers who had fibromyalgia. Conclusion In patients with fibromyalgia, smoking is a risk factor for cognitive dysfunction. Moreover, smokers with fibromyalgia were more likely to report increased severity of fibromyalgia symptoms, worse quality of life, more sleep problems, and increased anxiety compared with nonsmokers with fibromyalgia.

Abstract
Acceptor-sensitised 3-cube fluorescence resonance energy transfer (FRET) imaging (also termed as E-FRET imaging) is a popular fluorescence intensity-based FRET quantification method. Here, an automated E-FRET microscope with user-friendly interfaces was set up for dynamical online quantitative live-cell FRET imaging. This microscope reduces the time of a quantitative E-FRET imaging from 12 to 3 s. After locating cells, calibration of the microscope and E-FRET imaging of the cells can be performed automatically by clicking 'Capture' button on interfaces. E-FRET imaging was performed on the microscope for living cells expressing different FRET tandem constructs. Dynamical E-FRET imaging on the microscope for live cells coexpressing CFP-Bax and YFP-Bax treated by staurosporine (STS) revealed three Bax redistribution stages: Bax translocation from cytosol to mitochondria within 10 min, membrane insertion with conformational change on mitochondrial membrane within about 30 min, and subsequent oligomerisation within about 10 min. Because of excellent user-friendly interface and stability, the automated E-FRET microscope is a convenient tool for quantitative FRET imaging of living cell. LAY DESCRIPTION: Acceptor-sensitised 3-cube fluorescence resonance energy transfer (FRET) imaging (also termed as E-FRET) is a popular fluorescence intensity-based FRET quantification methods. E-FRET measurements are currently performed manually, and a complete FRET measurement takes about 12 s. E-FRET measurement necessitates not only a skilled operator and specialised equipment but also expertise in the interpretation of FRET signals, a considerable challenge in the application of FRET technology in living cells. Furthermore, manual E-FRET microscope is hard to perform dynamical quantitative FRET measurement, the ever-increasing applications in mapping the biochemical signal transduction within cells. Here, an automated E-FRET microscope with user-friendly interfaces was set up for dynamical online quantitative live-cell FRET imaging. This microscope reduces the time of a quantitative E-FRET imaging from 12 to 3 s. After locating cells, calibration of the microscope and E-FRET imaging of the cells can be performed automatically by clicking 'Capture' button on interfaces.

Abstract
Abstract
Background
The use of mesenchymal stem cells (MSCs) in clinical applications for the treatment of musculoskeletal disease is steadily increasing in office-based practice. The so-called “first generation” of MSCs is defined as autologous stem cells that have undergone minimal manipulation and are used for a homologous purpose. Systematic reviews of the clinical trials completed to date of such MSCs enable practitioners to better understand what is currently known about the outcomes and side effects of such treatments.
Study Design
A systematic review of human clinical studies of office-based MSC therapy for the treatment of painful degenerative musculoskeletal conditions.
Methods
A search of the Ovid MEDLINE, EMBASE, and Scopus databases was conducted from 2006 through September 2016. Seven hundred sixty-one records were identified from database searching, and two records from reference review of included papers. Studies with human subjects that evaluated treatment of musculoskeletal disease with minimally manipulated MSCs were included.
Results
Eight studies were included in this review based on selection criteria. A total of 941 patients were included, 841 of whom received cellular products, and no significant adverse events were reported. Symptomatology generally improved, though no differences were seen over controls where present.
Conclusion
Support in the literature is strongest for the use of bone marrow aspirate concentrate (BMAC) injections for the treatment of knee pain, but applications of the use of BMAC and peripheral blood–derived MSCs for the treatment of hip pain, tendon pain, and disc pain have all been reported. Further research is required, with large randomized controlled trials.

Abstract
BACKGROUND/AIMS MicroRNA (miRNA)-induced suppression of dendritic cells (DCs) has been implicated in many diseases. Therefore, accurate monitoring of miRNA endocytosis by DCs is important for understanding the role of miRNAs in many diseases. Recently, a method for measuring the co-localization of Argonaute 2 (AGO2)-associated miRNAs on laser-scanning confocal microscopy method was proposed to localize the miRNAs. But its definition was limited by the number of observed cells through its accuracy. METHODS In this study, a method based on imaging flow cytometry was developed to localize miR-590-5p with fluorescent probes in DCs. miR-590-5p proven to play an important role in tumor immunity. This method enabled the quantification, visualization and localization of the fluorescence intensity in 30,000 individual cells. RESULTS Using this method, the DCs with different endocytotic ability were distinguished. The behaviour of miR-590-5p during endocytosis under the stimulation of tumor antigen in DCs was observed, binding to its cognate target mRNA and degradation in DCs. CONCLUSION This method based on imaging flow cytometry provide an additional method to study miRNA processing in DCs, which makes it a valuable addition to existing miRNA research techniques.

Abstract
OBJECTIVE To establish an apicoectomy guide template design and manufacturing method, based on multi-source data fusion, computer aided design (CAD) and fused deposition modeling (FDM). The feasibility of the guide template was preliminary evaluated by the in vitro model experiment. METHODS An extracted upper anterior tooth, after root canal treatment, was optical scanned, after which the extracted upper anterior tooth was poured in an apicoectomy plaster model. Cone-beam computed tomography (CBCT) scanning of the apicoectomy plaster model was performed, after which optical scanning of the plaster model for apical resection surgery was carried out. All of the relevant CBCT and optical scanning data of the extracted upper anterior tooth and the apicoectomy plaster model were introduced into the Geomagic Studio 2012 software. The multi-source data fusion technology was used to virtually simulate the three-dimensional positional relationship of the extracted tooth, the dentition, the alveolar bone and the gingival, based on which, the three-dimensional design of the apicoectomy guide template was completed in the Geomagic Studio 2012 software. With the technology of fused deposition modeling, the apical resection surgical guide template was three-dimensionally printed with the material of polylactic acid (PLA). Under the guidance of the surgical guide template, the root apical resection was performed on the plaster model. After the apicoectomy, the extracted upper anterior tooth was taken off from the apicoectomy plaster model and then was given the optical scanning. The apical resection length and angle were calculated by the function of distance measurement and angle measurement, and the results were compared with the preset values. RESULTS The length of the apical resection was 2.88 mm along the direction of the long axis of the tooth, which was 0.12 mm lower than the preset 3 mm. The included angle between the apical resection plane and the long axis of the tooth was 77.9°, 12.1° lower than the preset 90°. CONCLUSION This study successfully established a digital design and production method of apicoectomy guide template by combing the multi-source data fusion, CAD and FDM technology. The design route and the production method are feasible. The study will provide a technology and methodology reference for the development of domestic special software for the digital design of apicoectomy guide template.

Abstract
BACKGROUND Preserving the donor's gallbladder during living donor liver transplantation (LDLT) is a better method for liver transplantation surgery, but not enough is known about gallbladder complications after the operation. METHODS We retrospectively investigated postsurgical donor gallbladder complications in clinical LDLT with gallbladder preservation. The feasibility of retaining the gallbladder during liver graft procurement is discussed. Ninety-one donors with retained gallbladder after LDLT with the hepatic left lateral sectionectomy (from June 2013 to October 2015) were retrospectively analyzed. Donors were followed for 12.6 to 40.7 months after surgery (median 26.1 months). Sonography was used to evaluate gallbladder characteristics before and after surgery. RESULTS Gallbladder function had recovered to almost normal 1 month after transplantation. Four donors (4.40%) experienced gallbladder enlargement that resolved after 3 days. Thickening of the gallbladder wall in 31 donors (34.07%) was restored within 2 to 75 days. Biliary sludge appeared in 9 donors (9.89%); 6 of them recovered within 3 to 34 days. Three (3.30%) and 1 donor (1.10%) suffered gallstone and gallbladder polyps, respectively, which persisted until the last follow-up. CONCLUSION The rate of postoperative complications of the gallbladder in donors was relative low. Preserving the gallbladder in liver transplantation donors during liver graft procurement is feasible and safe.

Abstract
BACKGROUND Transplantation of mesenchymal stem cells (MSCs) is a promising therapy for degenerative spine conditions. However, cell therapy for painful spine degeneration presently requires use of contrast agents during fluoroscopy-guided injections, and the effects of these agents on MSCs represents a gap in knowledge. OBJECTIVE To investigate the biological effects of contrast media (CM) that are coinjected with MSCs. DESIGN Prospective observational study. SETTING Academic medical center. PARTICIPANTS Patient-derived clinical-grade culture expanded MSCs. INTERVENTIONS Iohexol (Omnipaque300) was reduced to 12.5%, 25%, 50%, and 100% of the stock solution and incubated with MSCs for 30 minutes, 4 hours, and 48 hours. We also used complete media and 12.5%, 25%, 50%, 100% of phosphate-buffered saline as a control group. MAIN OUTCOME MEASURES We examined cytotoxicity of iohexol at different concentrations and exposure duration, as well as the potential for recovery over time. Cell counts, mitochondrial activity, and quantitative real time reverse-transcriptase polymerase chain reaction of related genes were analyzed immediately after exposure (day 0) and after 2 days of exposure (day 2). RESULTS Human MSCs exhibit a time- and concentration-dependent cytotoxic response to iodinated CM. A brief, 30-minute exposure did not affect MSCs function and viability. However, extended treatment with iohexol for 4 hours at 50% or higher concentration had a significant impact on both viability and gene expression in MSCs. CONCLUSIONS CM (Omnipaque300) is cytotoxic to MSCs in a time-and concentration-dependent manner. Hence, the concentration of CM that accompanies MSC injections should be carefully considered during MSC therapy for disk-degenerative diseases. LEVEL OF EVIDENCE To be determined.

Abstract
UNLABELLED Degenerative disk disease of the spine is a major cause of back pain and disability. Optimization of regenerative medical therapies for degenerative disk disease requires a deep mechanistic understanding of the factors controlling the structural integrity of spinal tissues. In this investigation, we sought to identify candidate regulatory genes controlling extracellular matrix synthesis in spinal tissues. To achieve this goal we performed high throughput next generation RNA sequencing on 39 annulus fibrosus and 21 nucleus pulposus human tissue samples. Specimens were collected from patients undergoing surgical discectomy for the treatment of degenerative disk disease. Our studies identified associations between extracellular matrix genes, growth factors, and other important regulatory molecules. The fibrous matrix characteristic of annulus fibrosus was associated with expression of the growth factors platelet derived growth factor beta (PDGFB), vascular endothelial growth factor C (VEGFC), and fibroblast growth factor 9 (FGF9). Additionally we observed high expression of multiple signaling proteins involved in the NOTCH and WNT signaling cascades. Nucleus pulposus extracellular matrix related genes were associated with the expression of numerous diffusible growth factors largely associated with the transforming growth signaling cascade, including transforming factor alpha (TGFA), inhibin alpha (INHA), inhibin beta A (INHBA), bone morphogenetic proteins (BMP2, BMP6), and others. CLINICAL SIGNIFICANCE this investigation provides important data on extracellular matrix gene regulatory networks in disk tissues. This information can be used to optimize pharmacologic, stem cell, and tissue engineering strategies for regeneration of the intervertebral disk and the treatment of back pain. © 2017 Orthopaedic Research Society.

Abstract
BACKGROUND The use of pediatric donor liver for pediatric liver transplantation (LT) remains controversial and few studies have focused on pediatric deceased donors. To address this issue, we decided to perform a retrospective research, trying to compare the clinical effects between deceased donor LTs (DDLTs) and living donor LTs (LDLTs). METHODS A retrospective review of pediatric LTs using grafts from deceased donors and living donors from June 2013 to August 2016 was performed. The children were divided into a DDLT group and a LDLT group based on their donor styles. The incidence of early vascular complications (VC), biliary complications, and graft and patient survival rates were observed between the 2 groups. RESULTS There were 217 cases of pediatric LTs performed in our hospital from June 2013 to August 2016 (83 DDLTs and 134 LDLTs). The 1-year cumulative survival rates of grafts and recipients were 89.16% and 91.57% in DDLTs, and 95.47% and 95.52% in LDLTs, respectively (P > .05). The incidence of early VC was lower in LDLTs than that in DDLTs (3.7% vs 19.3%, P < .001). The incidence of HAT in children aged less than 1 year was significantly higher in the DDLT group (P < .001) and can be up to 31.82%. The incidence of biliary complications was similar in the 2 groups (8.4% vs 13.5%, P = .285). CONCLUSIONS Pediatric DDLTs have similar graft and patient survival rates with LDLT. The incidence of early VC was higher in DDLTs, and children aged less than 1 year are at a higher risk of developing HAT.

Abstract
PURPOSE To explore the effects and mechanisms of anti-tumor necrosis factor-α (TNF-α) antibody on insulin resistance (IR) in rats with sepsis-induced stress hyperglycemia. METHODS The sepsis-induced stress hyperglycemic rat model was constructed by cecal ligation and puncture combined with the intraperitoneal injection of lipopolysaccharide. The rats were randomly divided into six groups: normal control (NC) group, surgical rats (Cntl) group, high-dose anti-TNF-α antibody therapy (TNF, 6 mg/kg) group, low-dose anti-TNF-α antibody therapy (Tnf, 3 mg/kg) group, insulin therapy (INS) group, and INS + Tnf group. The blood glucose and serum insulin concentrations were detected, followed by analysis of intraperitoneal glucose tolerance test (IPGTT) and hyperinsulinemic-euglycemic clamp. Finally, the expression levels of phospho-Akt (p-Akt), Akt, p-mTOR, mTOR, nuclear factor-κB (NFκB), I kappa beta kinase (IKKβ), and suppressor of cytokine signaling (SOCS-3) were detected by western blotting. RESULTS There was no significant difference in blood glucose concentrations among these groups, while the serum insulin concentration in TNF and Tnf groups was lower than that in the Cntl group at postoperative 6 h (P < 0.05). IPGTT analysis revealed that blood glucose level was lower in the TNF group than that in the Cntl group (P < 0.05). The glucose infusion rate in the Cntl group was lower than that in the Tnf and TNF groups (P < 0.05). The p-Akt/Akt, p-mTOR/mTOR ratio, and expression levels of NFκB, IKKβ and SOCS-3 were lower in the drug intervention than that in the Cntl group (P < 0.05). CONCLUSIONS Anti-TNF-α antibody could reduce IR by inhibiting AKt/mTOR signaling pathway and the expression levels of NFκB, IKKβ, and SOCS-3 in rats with sepsis-induced stress hyperglycemia.

Abstract
Objective Intra-articular injections of the C1–2 joint are an effective therapeutic option for pain generated from degenerative and inflammatory conditions affecting the joint. Limited information exists about the adverse events (AEs) associated with these injections. The primary aim of this study is to describe the frequency and type of AEs associated with C1–2 joint injections. The secondary aim is to identify clinical factors associated with the occurrence of AEs of C1–2 joint injections. Design/methods A retrospective chart review was conducted on all C1–2 joint injections performed at the Mayo Pain Medicine Clinic in Rochester, MN, from January 1, 2005 through July 31, 2015. AE data were extracted from procedural and post-procedural clinical notes. Analysis was conducted to determine correlations between any AE and demographic and clinical characteristics. Using univariate and multivariate logistic regression analyses, associations were determined. Results From January 1, 2005 to July 31, 2015, 135 C1–2 injections were performed on 72 patients. Overall, at least 1 AE was reported in 18.5% of the injections. The most common AEs were post-procedural increase in pain and procedural vascular contrast uptake. There was a significant association between AE occurrence and greater pre-procedural maximum pain score. Conclusions AEs from C1–2 joint injections occurred commonly, but there were no persistent or serious AEs associated with these injections. The data also demonstrate that patients with higher pre-procedural maximum pain scores are more likely to experience an AE.
