Abstract
STUDY DESIGN Imaging parameter study. OBJECTIVE Though lumbar alignment is better evaluated using standing radiograph than supine magnetic resonance imaging (MRI), few studies have researched this. Our study aimed to observe the correlation and difference in alignment between standing radiograph and supine MRI, and assess whether the change of position affects the lumbopelvic parameters. METHODS We analyzed 105 patients, measuring lumbar lordosis (LL), sacral slope (SS), pelvic tilt (PT), and pelvic incidence (PI). Inter- and intraparameter analyses were performed to identify any difference between standing radiograph and supine MRI. Statistical differences between the lumbopelvic parameters were compared. RESULTS There was excellent interobserver agreement for each parameter (interclass correlation coefficient > 0.75), and significant differences were observed in each parameter between radiograph and MRI (P < .05). Strong correlations were noted between the equivalent parameters in radiograph and MRI, both SS and PI were strongly correlated with LL in radiograph and MRI image, both PT and SS were strongly correlated with PI in radiograph and MRI image (r = -1.0 to -0.5 or 0.5 to 1.0). CONCLUSION Supine MRI obviously underestimated the measurements of lumbopelvic sagittal alignment parameters in standing radiograph. Therefore, standing lumbar radiographs should be obtained preoperatively in all surgical patients, not only supine MRI. In addition, we observed that PI was not a constant morphological parameter.

Abstract
Introduction: Type 2 diabetes mellitus (T2DM) is an independent risk factor of Alzheimer’s disease (AD), and populations with mild cognitive impairment (MCI) have high incidence to suffer from AD. Therefore, discerning who may be more vulnerable to MCI, among the increasing T2DM populations, is important for early intervention and eventually decreasing the prevalence rate of AD. This study was to explore whether the change of plasma β-amyloid (Aβ) could be a biomarker to distinguish MCI (T2DM-MCI) from non-MCI (T2DM-nMCI) in T2DM patients. Methods: Eight hundred fifty-two T2DM patients collected from five medical centers were assigned randomly to training and validation cohorts. Plasma Aβ, platelet glycogen synthase kinase-3β (GSK-3β), apolipoprotein E (ApoE) genotypes, and olfactory and cognitive functions were measured by ELISA, dot blot, RT-PCR, Connecticut Chemosensory Clinical Research Center (CCCRC) olfactory test based on the diluted butanol, and Minimum Mental State Examination (MMSE) test, respectively, and multivariate logistic regression analyses were applied. Results: Elevation of plasma Aβ1-42/Aβ1-40 is an independent risk factor of MCI in T2DM patients. Although using Aβ1-42/Aβ1-40 alone only reached an AUC of 0.631 for MCI diagnosis, addition of the elevated Aβ1-42/Aβ1-40 to our previous model (i.e., activated platelet GSK-3β, ApoE ε4 genotype, olfactory decline, and aging) significantly increased the discriminating efficiency of T2DM-MCI from T2DM-nMCI, with an AUC of 0.846 (95% CI: 0.794–0.897) to 0.869 (95% CI: 0.822–0.916) in the training cohort and an AUC of 0.848 (95% CI: 0.815–0.882) to 0.867 (95% CI: 0.835–0.899) in the validation cohort, respectively. Conclusion: A combination of the elevated plasma Aβ1-42/Aβ1-40 with activated platelet GSK-3β, ApoE ε4 genotype, olfactory decline, and aging could efficiently diagnose MCI in T2DM patients. Further longitudinal studies may consummate the model for early prediction of AD.

Developmental titanium dioxide nanoparticle exposure induces oxidative stress and neurobehavioral changes in zebrafish. AQUATIC TOXICOLOGY (AMSTERDAM, NETHERLANDS) 2021; 240:105990. [PMID: 34673465 DOI: 10.1016/j.aquatox.2021.105990] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/27/2021] [Revised: 09/01/2021] [Accepted: 10/02/2021] [Indexed: 06/13/2023]
Abstract
The widespread commercial application of titanium dioxide nanoparticles (TiO2 NPs) leads to ubiquitous presence of TiO2 NPs in the aquatic environment, which highlights the necessity to determine their potential adverse effects on aquatic organisms. The developing nerve system is particularly susceptible to environment perturbation. However, few studies have explored the developmental neurobehavioral toxicity of TiO2 NPs, especially at smaller particle size ranges (≤20 nm) that have relatively longer retention time in the water column. In this study, zebrafish embryos were exposed to non-teratogenic concentrations of 0.1 and 1 mg/L TiO2 NPs (average size of 14-20 nm) from 8 to 108 h post-fertilization (hpf) followed by various assessments at different time points up to 12 days post-fertilization (dpf). Our findings revealed that 1 mg/L TiO2 NPs perturbed the motor and social behaviors in larval zebrafish. These behavioral changes were characterized by decreased swimming speed in a locomotor response test at 5 dpf, increased travel distance in a flash stimulus test at 5 dpf, increased preference to the light zone in a light/dark preference test at 10 dpf, and increased mirror attack and percent time spent in the mirror zone in a mirror stimulus response assay at 12 dpf. Mechanistic examinations at 5 dpf revealed elevated cell apoptosis and oxidative stress. Cell apoptosis was characterized by increased acridine orange (AO) positive cells in the olfactory region and neuromasts of the lateral line system. Oxidative stress was characterized by increased lipid peroxidation, increased ROS production, and upregulated catalase (cat) gene expression. In addition, TiO2 NP exposure also upregulated genes associated with the developmental nervous system such as the growth associated protein 43 (gap43) and proliferating cell nuclear antigen (pcna). Our results suggest that the neurobehavioral changes in larvae exposed to 1 mg/L TiO2 NPs during early development may result from cell apoptosis and oxidative stress induced neuronal damages.

Implementation of Enhanced Recovery After Surgery (ERAS) protocol for elderly patients receiving surgery for intertrochanteric fracture: a propensity score-matched analysis. J Orthop Surg Res 2021; 16:469. [PMID: 34315507 PMCID: PMC8317361 DOI: 10.1186/s13018-021-02599-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Accepted: 07/01/2021] [Indexed: 01/20/2023] Open
Abstract
Purpose Enhanced Recovery After Surgery (ERAS) is a multimodal approach to perioperative care that aims to reduce patient perioperative complications, accelerate patient recovery, and improve patient satisfaction by refining and optimizing all perioperative management processes. By comparing two groups of patients before and after the implementation of ERAS for intertrochanteric fracture (ITF) with a matching analysis of propensity score (PS), we aimed to demonstrate that the implementation of ERAS protocol shortens the length of hospital stay (LOS), reduces pain, decreases the incidence of postoperative complications, and promotes functional recovery of the joint. Methods We selected 2 periods of 1 year, before (n=98patients) and after ERAS implementation (n=92patients). Data were collected on patient demographics, operative and perioperative details, LOS, VAS score, Harris score, and 30-day complications. ERAS-trained nurses are engaged to support patients at each step of the pre/per/postoperative process, including completing a satisfaction survey, with the help of a mobile app. PS analyses were used for dealing with confounding bias in this retrospective observational study. Results After PS matching, the outcomes of 124 well-balanced pairs of patients were compared (conventional vs ERAS). LOS was significantly reduced from 24.3±3.9 to 15.2±2.9 days (P<0.001). With the same preoperative VAS scores, we found that patients in the ERAS group had significantly lower postoperative VAS scores than those in the conventional group at days 3 and 7 (P<0.001), but the difference was not statistically significant at day 14. patients in the ERAS group had higher Harris scores than those in the conventional group at 1 and 3 months, but the difference was not significant at 6 months. In addition, we found that only one patient in the ERAS group developed complications, while nine patients in the conventional group developed different complications. There was no significant difference concerning the satisfaction survey. Conclusion The introduction of ERAS for ITF in our institution has resulted in a significant decrease in LOS, alleviated patient pain, promoted early recovery of patient’s hip function while effectively preventing complications, and obtained patient satisfaction.

Early life stage transient aristolochic acid exposure induces behavioral hyperactivity but not nephrotoxicity in larval zebrafish. AQUATIC TOXICOLOGY (AMSTERDAM, NETHERLANDS) 2021; 238:105916. [PMID: 34303159 PMCID: PMC8881052 DOI: 10.1016/j.aquatox.2021.105916] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/14/2021] [Revised: 07/12/2021] [Accepted: 07/14/2021] [Indexed: 05/12/2023]
Abstract
Aristolochic acids (AA) are nitrophenanthrene carboxylic acids found in plants of the Aristolochiaceae family. Humans are exposed to AA by deliberately taking herbal medicines or unintentionally as a result of environmental contamination. AA is notorious for its nephrotoxicity, however, fewer studies explore potential neurotoxicity associated with AA exposure. The developing nervous system is vulnerable to xenobiotics, and pregnant women exposed to AA may put their fetuses at risk. In the present study, we used the embryonic zebrafish model to evaluate the developmental neurotoxicity associated with AA exposure. At non-teratogenic concentrations (≤ 4 µM), continuous AA exposure from 8 to 120 hours post fertilization (hpf) resulted in larval hyperactivity that was characterized by increased moving distance, elevated activity and faster swimming speeds in several behavioral assays. Further analysis revealed that 8-24 hpf is the most sensitive exposure window for AA-induced hyperactivity. AA exposures specifically increased motor neuron proliferation, increased apoptosis in the eye, and resulted in cellular oxidative stress. In addition, AA exposures increased larval eye size and perturbed the expression of vision genes. Our study, for the first time, demonstrates that AA is neurotoxic to the developmental zebrafish with a sensitive window distinct from its well-documented nephrotoxicity.

Abstract
STUDY DESIGN Bibliometric analysis. OBJECTIVE Cervical spondylotic myelopathy (CSM) has become the most common cause of spinal cord dysfunction. Many topics of CSM still remain controversial. This study aimed to illustrate the overall knowledge structure and development trends of CSM. METHODS Research data sets were acquired from the Web of Science database and the time span was defined as "2000 to 2019." VOS viewer and Citespace software was used to analyze the data and generate visualization knowledge maps. Annual trends of publications, distribution, H-index status, co-authorship status, and research hotspots were analyzed. RESULTS A total of 2367 publications met the requirement. The largest number of articles was from the United States, followed by Japan, China, Canada, and India. The highest H-index was found for articles from the United States. The highest number of articles was published in Spine. The cooperation between the countries, institutes, and authors were relatively weak. Cervical sagittal alignment, predictive factor, diffusion tensor imaging, and the natural history of CSM may become a frontier in this research field. CONCLUSION The number of publications showed an upward trend with a stable rise. Most of the publications are limited to a few countries and institutions with relatively weak interaction. The United States, Canada, Japan, China, and India have made significant contributions to the field of CSM. The United States is the country with the highest productivity, not only in quality but also in quantity. Cervical sagittal alignment, predictive factor, diffusion tensor imaging, and the natural history of CSM are the research hotspots in the recent years.

Abstract
Both tetrabromobisphenol A (TBBPA) and titanium dioxide nanoparticle (TiO2 NP) have widespread commercial applications, resulting in their ubiquitous co-presence in the environment and biota. Although environmental chemicals exist as mixtures, toxicity studies are nearly always conducted with single chemicals. Few studies explore potential interactions of different chemical mixtures. In this study, we employ the sensitive developing nerve system in zebrafish to assess the neurotoxicity of TBBPA/TiO2 NP mixtures. Specifically, zebrafish embryos were exposed to solvent control (0.1% DMSO), 2 μM TBBPA, 0.1 mg/L TiO2 NP, and their mixture from 8 to 120 h post fertilization (hpf), and motor/social behavioral assessments were conducted on embryos/larvae at different developmental stages. Our results showed that TBBPA/TiO2 NP single or co-exposures increased spontaneous movement, decreased touch response and swim speed, and affected social behaviors of light/dark preference, shoaling, mirror attack and social contact. In particular, many of these phenotypes were manifested with higher magnitude of changes from the mixture exposure. These behavioral deficits were also accompanied with increased cell death in olfactory region and neuromasts in the lateral line system, increased ROS in gallbladder, pancreas, liver, and intestine, as well as increased lipid peroxidation and decreased ATP levels in whole larval tissue homogenates. Further, genes coding for key cell apoptosis marker and antioxidant enzyme were significantly upregulated by these two chemicals, in particular to their mixture. Interestingly, the co-presence of TBBPA also increased the mean particle size of TiO2 NP in the exposure solutions and the TiO2 NP content in larval tissue. Together, our analysis suggests that TBBPA/TiO2 NP induced behavioral changes may be due to physical accumulation of these two chemicals in the target organs, and TiO2 NP may serve as carriers for increased accumulation of TBBPA. To conclude, we demonstrated that TBBPA/TiO2 NP together cause increased bioaccumulation of TiO2, and heightened responses in behavior, cell apoptosis and oxidative stress. Our findings also highlight the importance of toxicity assessment using chemical mixtures.

Abstract
ABSTRACT Cervical spondylotic radiculopathy (CSR) is the most common type of cervical spondylosis, accounting for about 60% of the incidence of cervical spondylosis. Both cervical traction and traditional Chinese medicine hot compress are common and effective treatment for CSR. This study will be performed to investigate the effect of a combination of cervical traction and traditional Chinese medicine hot compress on CSR. In this non-blinded, randomized controlled trial, 100 eligible patients will be randomly divided into a treatment group (intermittent cervical traction combines with traditional Chinese medicine hot compress) and a control group (intermittent cervical traction combined with hot compresses). Before and after the intervention, the Visual Analog Scale score, Neck Disability Index score, and 20-score scale of symptoms will be evaluated at baseline and at 7, 14, 21, and 28 days. During the treatment period, any signs of acute adverse events, such as paralysis of aggravated pain, nausea, dizzy, and even syncope, will be recorded at each visit. Although intermittent cervical traction and traditional Chinese medicine hot compress have been used in the treatment of CSR in China for many years, there is no consensus on its effectiveness of combination therapy. This experiment will provide convincing evidence of the efficacy of intermittent cervical traction combined with traditional Chinese medicine hot compress in the treatment of CSR.

Abstract
Ninety percent of elderly patients with lumbar disc herniation (LDH) have problems with the mechanics of the spine and muscle tissue. Shi-style spine balance manipulation combined with guidance (Daoyin) of muscle and bone as an alternative therapy for LDH can tone the muscle groups around the spine and maintain optimal mechanical and static sagittal balance of the spine. This study will be performed to investigate the effect of a combination of Shi-style spine balance manipulation and Daoyin therapy on LDH in middle-aged and elderly patients. In this non-blinded, randomized controlled trial, 72 eligible patients will be randomly divided into a treatment group (Shi-style spine balance manipulation combined with Daoyin therapy) and a control group (lumbar mechanical traction). Before and after the intervention, lumbar X-ray and magnetic resonance imaging examinations will be performed to observe the sagittal balance parameters of the spine and pelvis and the lumbar muscle strength. The visual analog scale score, Oswestry disability index score, and pressure pain threshold will be evaluated at baseline and at 2, 4, 12, and 24 weeks. During the treatment period, any signs of acute adverse events, such as paralysis of the lower extremities or cauda equina syndrome, will be recorded at each visit. Although Shi-style spine manipulation combined with Daoyin therapy has been used in the treatment of LDH in middle-aged and elderly people in China for many years, there is no consensus on its effectiveness. This experiment will provide convincing evidence of the efficacy of Shi-style spine manipulation combined with Daoyin therapy in the treatment of LDH in middle-aged and elderly people.

Abstract
OBJECTIVES Plantar fasciitis (PF) is the most common cause of heel pain. Though PF is self-limited, it can develop into chronic pain and thus treatment is needed. Early and accurate prognostic assessment of patients with PF is critically important for selecting the optimal treatment pathway. Nevertheless, there is no scoring system to determine the severity of PF and no prognostic model in choosing between conservative or surgical treatment. The study aimed to develop a novel scoring system to evaluate the severity of plantar fasciitis and predict the prognosis of conservative treatment. METHODS Data of consecutive patients treated from 2014 to 2018 were retrospectively collected. One hundred and eighty patients were eligible for the study. The demographics and clinical characteristics served as independent variables. The least follow-up time was 6 months. A minimal reduction of 60% in the visual analog scale (VAS) score from baseline was considered as minimal clinically important difference (MCID). Those factors significantly associated with achieving MCID in univariate analyses were further analyzed by multivariate logistic regression. A novel scoring system was developed using the best available literature and expert-opinion consensus. Inter-observer reliability and intra-observer reproducibility were evaluated. The appropriate cut-off points for the novel score system were obtained using receiver operating characteristic (ROC) curves. RESULTS The system score = VAS (0-3 point = 1; 3.1-7 point = 3; 7.1-10 point = 5) + duration of symptoms (<6 months = 1; ≥1 6 months = 2) + ability to walk without pain (>1 h = 1; ≤1 h = 4) + heel spur in X-ray (No = 0; Yes = 2) + high intensity zone (HIZ) in MRI (No = 0; Yes = 2). The total score was divided in four categories of severity: mild (2-4 points), moderate (5-8 points), severe (9-12 points), and critical (13-15 points). Inter-observer agreement with a value of 0.84 was considered as perfect reliability. Intra-observer reproducibility with a value of 0.92 was considered as perfect reproducibility. The optimum cut-off value was 10 points. The sensitivity of predictive factors was 86.37%, 84.21%, 91.22%, 84.12%, and 89.32%, respectively; the specificity was 64.21%, 53.27%, 67.76%, 62.37%, and 79.58%, respectively; the area under curve was 0.75, 0.71, 0.72, 0.87, and 0.77, respectively. The Hosmer-Lemeshow test showed a good fitting of the score system with an overall accuracy of 90.6%. CONCLUSIONS Based on prognostic factors, the present study establishes a novel scoring system which is highly comprehensible, reliable, and reproducible. This score system can be used to identify the severity of plantar fasciitis and predict the prognosis of conservative treatment accurately. The application of this scoring system in clinical settings can significantly improve the decision-making process.

Abstract
AbstractBillions of Internet of Thing (IoT) devices are deployed in edge network. They are used to monitor specific event, process and to collect huge data to control center with smart decision based on the collected data. However, some malicious IoT devices may interrupt and interfere with normal nodes in data collection, causing damage to edge network. Due to the open character of the edge network, how to identify the credibility of these nodes, thereby identifying malicious IoT devices, and ensure reliable data collection in the edge network is a great challenge. In this paper, an Active and Verifiable Trust Evaluation (AVTE) approach is proposed to identify the credibility of IoT devices, so to ensure reliable data collection for Edge Computing with low cost. The main innovations of the AVTE approach compared with the existing work are as follows: (1) In AVTE approach, the trust of the device is obtained by an actively initiated trusted detection routing method. It is fast, accurate and targeted. (2) The acquisition of trust in the AVTE approach is based on a verifiable method and it ensures that the trust degree has higher reliability. (3) The trust acquisition method proposed in this paper is low-cost. An encoding returned verification method is applied to obtain verification messages at a very low cost. This paper proposes an encoding returned verification method, which can obtain verification messages at a very low cost. In addition, the strategy of this paper adopts initiation and verification of adaptive active trust detection according to the different energy consumption of IoT devices, so as to reliably obtain the trust of device under the premise of ensuring network lifetime. Theoretical analysis shows that AVTE approach can improve the data collection rate by 0.5 ~ 23.16% while ensuring long network lifetime compared with the existing scheme.

Abstract
BACKGROUND Cervical spondylotic myelopathy (CSM) is the most serious type of cervical spondylosis, which is often treated surgically in patients with progressive neurological symptoms following ineffective conservative treatment. However, some patients have residual symptoms such as neck pain, stiffness, and C5 nerve palsy after surgery. The Qishe pill can effectively relieve the symptoms of neck pain and numbness, but there is no evidence showing the efficacy and safety of the Qishe pill in treating symptoms after spinal cord surgery. METHODS/DESIGN A multicenter, randomized controlled clinical trial will be conducted to evaluate the efficacy and safety of the Qishe Pill. A total of 330 patients with CSM who receive surgical treatment will be randomly divided into 2 groups, treated for 12 weeks and with a 1-year follow-up. The primary outcome will be Japanese Orthopaedic Association score from the baseline to 4 weeks, 12 weeks, 24 weeks, and 48 weeks after surgery. Secondary outcomes will include Visual Analogue Scale score, Neck Disability Index, and imaging indicators (including magnetic resonance imaging and X-ray). Additionally, adverse reactions will be observed and recorded as safety indicators. DISCUSSION Although the Qishe pill can effectively improve the discomfort of the neck and upper limbs in clinical applications, there is a lack of clinical research on postoperative patients. This study will investigate the efficacy and safety of the Qishe pill in treating postoperative symptoms of CSM. TRIAL REGISTRATION Clinical Trials.gov ID: ChiCTR1900028173.

BACKGROUND To illustrate the research framework, overall knowledge structure, and development trends of Chinese medicine (CM) treatment for osteosarcoma (OS) by using a bibliometric analysis and newly developed visualization tools. METHODS Research datasets were acquired from the Web of Science (WOS) database from January 1, 1980 to September 30, 2019. VOS viewer and Citespace software was used to analyze the data and generate visualization knowledge maps. Annual trends of publications, distribution of institutes, distribution of journals, citation and H-index status, co-authorship status, research hotspots and co-citation status were analyzed. RESULTS A total of 223 publications in the WOS database met the requirement. The number of published articles showed a rise but the citation frequency and the H-index of China were relatively low. The cooperation between the countries, institutes and authors were relatively weak. Most publications were basic researches. Most of the previous researches focused on basic mechanisms of CM in treating OS, and therapy and improvement of dosage form may become a frontier in this research field. CONCLUSIONS Compared with other fields, the field of CM treatment for osteosarcome is still in infancy. The distribution of researches is imbalanced and cooperation between countries, institutions and authors remains to be strengthened. Furthermore, basic research occupies an absolute dominant position, and the exploration of the molecular mechanism of CM in preventing and treating OS may become a key point in the future.

Abstract
BACKGROUND Neck pain, sensory disturbance and motor dysfunction in most patients suffered cervical spondylotic myelopathy (CSM). However, some conservative treatments are limited by their modest effectiveness. In the other hand, surgical treatment is necessary when symptoms are refractory to conservative treatments and neurological function of the patients has deteriorated. Many patients use complementary and alternative medicine, including traditional Chinese medicine, to address their symptoms. The purpose of the present study is to examine effectiveness and safety of Yiqi-Huayu-Tongsui (YQHYTS) granule, a compound traditional Chinese herbal medicine, on symptoms in patients with mild or moderate CSM. METHODS/DESIGN A randomized, double blinded, placebo-controlled clinical trial to evaluate the efficacy and safety of YQHYTS granule is proposed. 72 patients in Longhua Hospital with the diagnosis of mild or moderate CSM will be randomly allocated into 2 groups, and treated with YQHYTS granule or placebo. The prescription of the trial drugs (YQHYTS granule/placebo) is 20 grams twice a day for 3 months. The primary outcome measurements include visual analog scale, Japanese Orthopedic Association, and Neck Disability Index score. The secondary outcome measurements are electromyogram and Pfirrmann classification. DISCUSSION YQHYTS granule has been established and applied in Longhua Hospital for many years. As it has a potential benefit in treating mild or moderate CSM, we designed a double-blind, prospective, randomized controlled trial and would like to publish the results and conclusions later. If YQHYTS granule can alleviate neck pain, sensory disturbance, and even motor dysfunction without adverse effects, it may be a unique strategy for the treatment of mild or moderate CSM.

Abstract
Background Intertrochanteric fracture (ITF) is increasing with the rapid increase in the aging population, often causes a high mortality rate in old patients and increases the economic burden of the family and society. ERAS (Enhanced Recovery after Surgery) is a powerful guarantee for patients to accelerate their recovery after surgery. TCM (traditional Chinese medicine) promotes repair of injured tissues and eliminates traumatic aseptic inflammation. Therefore, this prospective randomized controlled clinical trial aims to evaluate the clinical effect of the evidence-based ERAS pathway of integrating TCM with western medicine on perioperative outcomes in ITF patients undergoing intramedullary fixation and provide reliable evidence-based data for applying the program to clinical practice. Methods/design We will conduct a prospective randomized, blinded, controlled trial to compare the effectiveness of ERAS care pathway with traditional care pathway and to investigate whether the ERAS care pathway can improve the perioperative outcome in ITF patients undergoing intramedullary fixation. A total of 60 patients with ITF will be enrolled and treated with the two care pathway, respectively. Length of stay, economic indicators, Harris score, VAS score, time to get out of bed, 30-day readmission rates, postoperative transfusion rates, discharge to home, and mortality will be evaluated. Any signs of acute adverse reactions will be recorded at each visit during treatment. Discussion Although an evidence-based process using the best available literature and Delphi expert-opinion method has been used to establish an ERAS pathway of integrating TCM with western medicine, there is a lack of consensus about its effectiveness. This trial will provide convincing evidence about the effect of ERAS pathway. Trial registration Registered on 12 October 2019. Trial number is ChiCTR1900026487.

Abstract
OBJECTIVE To establish a simple and reliable model of cervical vertigo in rats with hyperactivity of liver-yang syndrome, and to establish a simple and feasible method for evaluating the degree of vertigo in animals. METHODS SPF male SD rats (aged 8 weeks, weighing 280 to 320 g) were randomly divided into 4 groups (6 rats in each group). The model of cervical vertigo of hyperactivity of liver yang syndrome (joint modeling group) was established by combining local injection of lauromacrogol (hardener) and receiving fuzi decoction by gavage. The joint modeling group was compared with the hardener group, the fuzi decoction group and the blank control group. The vertigo degree of rats was measured by the time of passing through a glass tube (running time) before modeling, 2 weeks and 3 weeks after the established model. RESULTS There was no statistical difference in the running time between control group and fuzi decoction group, between joint modeling group and hardener group. The running time in the hardener group and the joint modeling group was longer than that in the control group (P< 0.05), and was even longer than that in the fuzi decoction group (P<0.01). There was significant difference in running time after modeling compared with that before modeling (P<0.05); there was no significant difference in running time between 2 and 3 weeks after modeling (P>0.05). CONCLUSION This method can effectively establish a rat model of cervical vertigo with hyperactivity of liver-yang syndrome, and the running time can reflect the degree of vertigo in rats to a certain extent. This experiment provides a simple and feasible animal model and detection method for research of cervical vertigo in the future.

Abstract
BACKGROUND Most patients with spinal tumors suffer no symptoms or have mild symptoms, but about 14% of patients have refractory pain caused by mechanical instability, or symptoms of spinal cord damage caused by epidural spinal cord compression. The Spinal Instability Neoplastic Score (SINS) and Kostuik classification are commonly used to evaluate spinal stability, and help to make a more detailed operation plan. The objectives of this study are to evaluate the reliability and reproducibility of the SINS and Kostuik classification, and to explore their clinical application value. METHODS All 80 patients with spinal tumors were enrolled. Six spine surgeons who have certain clinical experience were selected. Patients were scored according to the SINS scoring system and classification was determined according to the Kostuik system. We used Fleiss and Cohen κ values to check the coefficient consistency for multifactors. We used Cohen κ value to check the interobserver reliability and intraobserver reproducibility. After 12 weeks, we repeated the analysis. RESULTS The interobserver reliability and intraobserver reproducibility of the SINS scoring system were near perfect with values of 0.831 and 0.874, respectively. The interobserver reliability and intraobserver reproducibility of the Kostuik classification system were moderate with values of 0.505 and 0.595, respectively. CONCLUSIONS Compared with the Kostuik classification system, the SINS scoring system has better interobserver reliability and intraobserver reproducibility, which can be widely used in clinical practice and has great significance in the decision-making of spinal tumor treatment. Although the Kostuik classification system is often used in clinical practice, it shows inferior reliability and reproducibility in our study.

Abstract
BACKGROUND Symptomatic degenerative lumbar spondylolisthesis (DLS) presents spinal problems in daily life. Shi-style lumbar manipulation (SLM), as an alternative treatment for DLS, is popular in China. SLM is based on the channels and collaterals theory of the traditional Chinese medicine, in which the symptoms are believed to result from channel blockage and joint displacement. However, there is no solid evidence to show the effect of the SLM on the management of symptomatic DLS. METHODS/DESIGN We conduct a prospective randomized, blinded, controlled trial to compare the effectiveness of SLM with mechanical lumbar traction and explore whether it could be a potential therapy for symptomatic DLS. A total of 60 patients with symptomatic DLS will be enrolled and treated with the SLM or mechanical lumbar traction for 2 weeks. VAS score and SF-36 questionnaire were assessed at baseline and at 2, 4, 12, and 24 weeks. Any signs of acute adverse reactions, such as lower limb paralysis or syndrome of cauda equina, will be recorded at each visit during treatment. DISCUSSION Although the SLM has been used in China for many years to treat symptomatic DLS, there is a lack of consensus about its effectiveness. This trial will provide convincing evidence about the effect of SLM on symptomatic DLS. TRIAL REGISTRATION Registered on 6 January 2019; the trial number is ChiCTR1900020519 .

Abstract
BACKGROUND Primary melanocytic neoplasms in the central nervous system are rare lesions arising from leptomeningeal melanocytes. These lesions produce neural deficits that resemble those of a meningioma or a schwannoma radiologically. CASE DESCRIPTION A tumor around the left S1 root with an extension into the left paraspinal compartment was identified in a 32-year-old female with persistent left leg pain for 6 months. The tumor was hyperintense on T1-weighted image and hypointense on T2-weighted image with a homogeneous enhancement. The clinical features, radiologic presentations, treatment choice, and pathologic characteristic were illustrated. The treatment outcome was compared with those reported in the previous literature. The tumor was en-bloc resected with the S1 nerve root reserved. Grossly, the tumor was a soft, capsulated, well-circumscribed, black pigmented lesion. Immunohistochemistry revealed that the tumor cells were positive for HMB-45, S-100 protein, and vimentin. The patient's symptoms were greatly relieved postoperatively. No signs of local recurrence were observed. CONCLUSIONS Spinal meningeal melanocytoma inside the nerve root is rare and benign. It is difficult to diagnose and often misdiagnosed as schwannoma or meningioma. HMB-45 has been suggested as a significant marker for the diagnosis of meningeal melanocytoma. Complete surgical resection is recommended as the primary treatment. Radiotherapy, chemotherapy, and other treatments can be selected as adjuvant therapies, but their effects are controversial. The recurrence and metastasis rates also remain unclear.

Abstract
OBJECTIVE Designing surgical strategies for ossified lesions in the upper cervical spine is challenging owing to the complex anatomic structures. The present study aimed to clarify the prevalence of ossified lesions in the upper cervical spine in patients with ossification in the posterior longitudinal ligament and illustrate the clinical features, radiological findings, and surgical outcomes of this abnormality. METHODS Demographic and clinical data were collected for all patients preoperatively and included age, gender, body mass index, alcohol and tobacco use, history of diabetes, visual analog score, and Japanese Orthopaedic Association score. The cervical angle, morphology of ossification in the posterior longitudinal ligament, K-line, occupation ratio, space available for the spinal cord, high-intensity zone, and compression ratio of the spinal cord were calculated. The operative approach, technique used, and complications were recorded. RESULTS A total of 38 patients were enrolled. The upper cervical segment in 23 patients was not surgically addressed. In the group with the upper cervical segment addressed surgically, 10 patients were treated with C3-C6 open-door laminoplasty and C2 partial laminectomy, 1 with C1-C7 laminoplasty, 1 with C2-C7 laminoplasty, 2 with C3-C6 total and C2 partial laminectomy, and 1 with C1-C5 laminectomy and occipitocervical fusion. CONCLUSIONS The development of ossified lesions in the upper cervical spine has a high incidence. Decompressive surgery for upper cervical spine segments should be recommended for patients with severe narrowing of the spinal canal and a high signal intensity that extends to the upper cervical segment of the spinal cord. We hope that the findings from the present study will aid in clinical decision-making and provide useful information that can be incorporated into future guidelines.

Abstract
Surgical therapy is vital for thoracolumbar burst fracture in restoring vertebral height, correcting kyphosis, decompressing nervous, and maintaining stability. Patients have unexpectedly lower hemoglobin levels postoperatively, which is remarkably inconsistent with the measured blood loss. However, hidden blood loss (HBL) is often neglected.To investigate HBL during perioperative period and determine its influential factors after surgery.A total of 68 patients who underwent surgery in our institution between January 2015 and January 2017 were included in the study. The demographic information, including the patients' age, gender, weight, height, duration of symptoms, surgery approach, time of operation, volume of drainage, classification of fracture, percentage of vertebral height loss and restoration, was collected. HBL was calculated according to the Gross formula. Influential factors were further analyzed using multivariate linear regression analysis.The mean HBL was 303.5 (range 18.4-803.5) mL, accounting for 67.5% of total blood loss. It indicated that the amount of HBL was much higher than we expected. Multiple and stepwise regression analysis revealed that blood loss, preoperative activated partial prothrombin time (APPT), percentage of anterior and medium vertebral height restoration were positively correlated with HBL. The association between HBL and the influential factors was analyzed based on the regression model equation: HBL = [1 + e [216.737 + 0.627*blood loss + 10.817*APTT + 207.549*anterior height restoration + 20.002*medium height restoration]]-1.HBL during perioperative period accounted for a substantial portion of the total blood loss and was much larger than what we thought. The blood loss, preoperative APPT, percentage of anterior and medium vertebral height restoration were positively correlated with HBL. Therefore, more attention needs to be paid to HBL to ensure patients' safety.

Abstract
INTRODUCTION Guillain-Barré syndrome (GBS) is an inflammatory demyelinating autoimmune disease, associated with blood-nerve barrier breakdown, inflammatory cells infiltration, and cytokine leakage in the peripheral nervous system. Currently, it has been revealed that monocytes play key roles in the inflammatory response. Therefore, we aimed to assess the correlation between monocyte count and GBS in this study. METHODS Retrospective study was conducted in 114 patients with GBS and 120 age- and gender-matched individuals. RESULTS Absolute monocyte count in patients with GBS was higher than that in healthy controls (0.61 ± 0.24 vs 0.41 ± 0.10; P < .001). Interestingly, monocyte count had significant positive correlations with CRP, ESR, and disease severity of GBS (r = .244, P = .009; r = .269, P = .004; r = .322, P < .001). A cutoff value of 0.515 for monocyte count was observed in patients with GBS (areas under the curve = 0.808, 95% confidence interval = 0.749-0.868, P < .001). Meanwhile, absolute monocyte count was independently associated with GBS in logistic regression analysis (odds ratio = 2.291, 95% confidence interval = 3.557-27.493, P < .001). CONCLUSION Our findings demonstrated that elevated monocyte count is independently associated with GBS patients, and suggested monocyte count is positively associated with disease severity of GBS.

Abstract
BACKGROUND Lumbar disk herniation (LDH) is considered a common cause of lumbosacral radiculopathy. Epidural steroid injection is a common method to treat inflammation associated with low back-related leg pain. Spinal manipulations are widely used, and systematic reviews have also shown that these manipulations are more effective than placebos. OBJECTIVE Due to the absence of clinical evidence, we designed a prospective, randomized, single-blind controlled trial in patients with LDH with radiculopathy, aiming to detect the safety and clinical efficacy of targeted indwelling catheter combined with "4-step" manipulative therapy in patients with LDH. METHODS Patient visits were performed at baseline and days 1, 3, 7, and 28 after treatment. Clinical outcomes were measured using visual analog scale for back and leg pain, Oswestry Disability Index (ODI), and clinical symptom scores of the Japanese Orthopedic Association (JAO). RESULTS The study included 85 eligible patients. They were categorized with a randomization schedule into a Catheter Group (N = 43) and No-Catheter Group (N = 42). Between the measurement points, there was a statistically significant difference in the visual analog scale (back) at days 1, 3, and 7 of follow-up after treatment between the 2 groups. The change was statistically different at days 1 and 3, and a higher change was observed in the Catheter Group compared with the No-Catheter Group. There was a statistically significant difference in change of JOA and ODI scores at day 1 of follow-up after treatment between the 2 groups, and a greater change was seen in the Catheter Group at days 1 and 3 compared with the No-Catheter Group. LIMITATIONS The small sample size was small, and the follow-up time was short. The study also lacked documents of adjuvant therapies, like individual patient exercise routines and analgesic drug therapy. CONCLUSION Both methods were effective in reducing pain intensity and functional disability compared with pretreatment. The Catheter Group showed a more significant decrease in visual analog scale and greater changes in JOA and ODI scores of short/term follow-up, compared with the No-Catheter Group. The therapy project was safe.

Abstract
BACKGROUND AND OBJECTIVES Paraganglioma rarely develops in the spine. With few cases reported, little knowledge about this disease was known. The objective of this study is to illustrate the clinical features, imaging manifestations, pathological appearances and long-term outcomes of the consecutive surgeries by literature review. METHODS The clinical and follow-up data of 18 patients who were diagnosed of spinal paraganglioma and treated with surgeries in our hospitals from 2003 to 2014 were retrospectively analyzed. RESULT A total of fourteen patients radiographed of intra-spinal tumor underwent extra-capsular tumor resection. Of five patients with obvious vertebral bone damage, four cases underwent piecemeal resection, and the left one with sacral tumor underwent en bloc tumor excision. Spinal reconstruction was performed in all cases. Follow-up lasted for 16-96 months (44.1 months on average). There was no local recurrence or distant metastasis in cases without obvious bone invasion. Of those five cases with vertebral bone damage, one case suffered and survived from the repeat relapse of T1 vertebral body tumor. Local recurrence was not observed in one case with T10 vertebral tumor after tumor resection, but the tumor metastasized to T2 attachment during the follow-up and was finally eradicated by re-operation. No tumor recurrence was observed in the left three cases. CONCLUSION Paraganglioma, usually benign, rarely occurs. Surgical resection, especially complete surgical resection, is preferred to treat spinal paraganglioma. Chemotherapy, radiotherapy, use of octreotide and other somatostatin are selected as adjuvant therapies, but their effects remain unknown.
