Abstract
Synovial chondromatosis (SC) of the temporomandibular joint (TMJ) is a rare benign disease associated with the formation of multiple cartilaginous nodules in the synovial tissue of the TMJ. This can result in pain, swelling, clicking, limited mouth opening, and osseous degenerative joint changes. A retrospective cross-sectional study was performed to summarize the clinical features, radiographic findings, and surgical and histopathological findings of TMJ SC patients who underwent open surgery over a 24-year period. A radiographic scoring system was used to evaluate osseous changes and correlate condyle and joint fossa degeneration. The study included 38 patients and focused on 38 joints. All 38 of these joints showed degenerative changes in the condyle, while 37 showed osseous degenerative changes in the articular fossa. The degree of condylar degenerative changes was related to the duration of the chief complaints (r = 0.342, P = 0.036) and the histopathological stage of the TMJ SC (r = 0.440, P = 0.006), while the degree of joint fossa degenerative changes was associated with the radiographic extent of the SC (r = 0.504, P = 0.001), type of calcification (r = 0.365, P = 0.024), and the histopathological stage (r = 0.458, P = 0.004).

Abstract
BACKGROUND The neuroanatomical alteration in bipolar II depression (BDII-D) and its associations with inflammation, childhood adversity, and psychiatric symptoms are currently unclear. We hypothesize that neuroanatomical deficits will be related to higher inflammation, greater childhood adversity, and worse psychiatric symptoms in BDII-D. METHODS Voxel- and surface-based morphometry was performed using the CAT toolbox in 150 BDII-D patients and 155 healthy controls (HCs). Partial Pearson correlations followed by multiple comparison correction was used to indicate significant relationships between neuroanatomy and inflammation, childhood adversity, and psychiatric symptoms. RESULTS Compared with HCs, the BDII-D group demonstrated significantly smaller gray matter volumes (GMVs) in frontostriatal and fronto-cerebellar area, insula, rectus, and temporal gyrus, while significantly thinner cortices were found in frontal and temporal areas. In BDII-D, smaller GMV in the right middle frontal gyrus (MFG) was correlated with greater sexual abuse (r = -0.348, q < 0.001) while larger GMV in the right orbital MFG was correlated with greater physical neglect (r = 0.254, q = 0.03). Higher WBC count (r = -0.227, q = 0.015) and IL-6 levels (r = -0.266, q = 0.015) was associated with smaller GMVs in fronto-cerebellar area in BDII-D. Greater positive symptoms was correlated with larger GMVs of the left middle temporal pole (r = 0.245, q = 0.03). CONCLUSIONS Neuroanatomical alterations in frontostriatal and fronto-cerebellar area, insula, rectus, temporal gyrus volumes, and frontal-temporal thickness may reflect a core pathophysiological mechanism of BDII-D, which are related to inflammation, trauma, and psychiatric symptoms in BDII-D.

Abstract
BACKGROUND Alterations in brain functional connectivity (FC) have been frequently reported in adolescent major depressive disorder (MDD). However, there are few studies of dynamic FC analysis, which can provide information about fluctuations in neural activity related to cognition and behavior. The goal of the present study was therefore to investigate the dynamic aspects of FC in adolescent MDD patients. METHODS Resting-state functional magnetic resonance imaging data were acquired from 94 adolescents with MDD and 78 healthy controls. Independent component analysis, a sliding-window approach, and graph-theory methods were used to investigate the potential differences in dynamic FC properties between the adolescent MDD patients and controls. RESULTS Three main FC states were identified, State 1 which was predominant, and State 2 and State 3 which occurred less frequently. Adolescent MDD patients spent significantly more time in the weakly-connected and relatively highly-modularized State 1, spent significantly less time in the strongly-connected and low-modularized State 2, and had significantly higher variability of both global and local efficiency, compared to the controls. Classification of patients with adolescent MDD was most readily performed based on State 1 which exhibited disrupted intra- and inter-network FC involving multiple functional networks. CONCLUSIONS Our study suggests local segregation and global integration impairments and segregation-integration imbalance of functional networks in adolescent MDD patients from the perspectives of dynamic FC. These findings may provide new insights into the neurobiology of adolescent MDD.

Abstract
Background Florbetapir positron emission tomography (AV45 PET) is a widely employed modality for detecting cerebral amyloid-β (Aβ) deposition. However, in clinical settings, patients with cognitive impairment are frequently unable to sustain adequate stillness during the scanning procedure. Therefore, we aimed to investigate the effects of a short acquisition time on the image quality and Aβ detectability of AV45 PET. Methods In this cross-sectional study, 29 patients with Alzheimer's disease (AD) and 13 healthy participants underwent 15-minute AV45 PET/magnetic resonance imaging scanning. The PET data were subsequently reconstructed into 15-, 10-, 8-, 6-, 4-, 2-, and 1-minute duration groups (G15, G10, G8, G6, G4, G2, and G1). Subjective PET image quality was scored based on a 5-point Likert scale (poor-excellent: 1-5), and objective image quality was evaluated by the signal-to-noise ratio (SNR) of the 1 cm3 region of interest (ROI) inside the cerebellum. Aβ detectability was assessed by the calculation of regional standardized uptake value ratio (SUVR) values in all groups. The Kruskal-Wallis rank sum test and paired t-test were performed to compare the subjective scores, SNR, and SUVR values. The visual inspection was also performed by 2 nuclear physicians to give a binary diagnosis to each case. Results The subjective scores were decreased in the groups with shortened scanning time relative to the G15 group (4.67±0.48, all P<0.05). Notably, a good image quality score was also given to the G10 group (4.40±0.63), and sufficient image quality could be achieved with the G8 (3.86±0.68) and G6 (3.14±0.52) groups. The SNR values were decreased by 10.33%, 17.74%, and 23.26% in the G10, G8, and G6 group, respectively (all P<0.05). Compared with the G15 group (1.48±0.16), the composite SUVR values were increased in the G10 (1.50±0.16), G8 (1.50±0.17), and G6 groups (1.51±0.18, all P<0.05). By visual inspection, the diagnoses of each case in the G10, G8, and G6 group were identical with those in the G15 group. Conclusions The acquisition time of AV45 PET is required to reach at least 6 minutes to achieve acceptable image quality and maintained Aβ detectability.

Abstract
The development of preeclampsia (PE) is associated with the impaired trophoblast motility. MicroRNAs (miRs) contribute to the modulation of trophoblast invasion. In the current study, the role of miR-206/AGTR1 in the TNF-alpha-induced invasion defect of trophoblasts was explored. The levels of miR-206 and ATGR1 in clinical placenta tissues were investigated. Trophoblasts were treated with TNF-alpha, and the levels of miR-206 and ATGR1 were modulated. Changes in cell viability, invasion, and inflammation in trophoblasts were detected. The level of miR-206 was induced, while the level of AGTR1 was suppressed in placenta tissues. In in vitro assays, TNF-alpha suppressed viability, induced inflammatory response, inhibited invasion, upregulated miR-206, and down-regulated AGTR1. The inhibited expression of miR-206 or the overexpression of AGTR1 counteracted the effects of TNF-alpha, indicating the key role of the miR-206/AGTR1 in progression of PE. Collectively, miR-206 suppressed viability, induced inflammatory response, and decreased invasion of trophoblasts by inhibiting AGTR1.

Abstract
AIM Elevated inflammation and larger choroid plexus (ChP) volume has been previously identified in mood disorders. Connections between inflammation, ChP, and clinical symptoms in bipolar II depression (BDII-D) are unclear. Data-driven clustering based on neuroanatomical phenotypes may help to elucidate neurobiological associations in BDII-D. METHODS Inflammatory cytokines, clinical symptoms, and neuroanatomical features were assessed in 150 BDII-D patients. Sixty-eight cortical surface area (SA) and 19 subcortical volumes were extracted using FreeSurfer. The ChP volume was segmented manually using 3D Slicer. Regularized canonical correlation analysis was used to identify significantly correlated components between cortical SA and subcortical volumes (excluding the ChP), followed by k-means clustering to define brain-derived subgroups of BDII-D. Low-grade inflammation was derived by averaging the standardized z scores of interleukin (IL)-6, IL-1β, and tumor necrosis factor-α (TNF-α), which were computed to create a composite z-value score. Partial Pearson correlations followed by multiple comparison correction were conducted to explore associations between inflammation, clinical symptoms, and ChP volume. RESULTS Subgroup I demonstrated smaller subcortical volume and cortical SA, higher inflammation, and larger ChP volume compared with subgroup II. Greater ChP volume was associated with a higher low-grade inflammation (mean r = 0.289, q = 0.003), CRP (mean r = 0.249, q = 0.007), IL-6 (left r = 0.200, q = 0.03), and TNF-α (right r = 0.226, q = 0.01), while greater IL-1β was significantly associated with severe depressive symptoms in BDII-D (r = 0.218, q = 0.045). CONCLUSIONS Neuroanatomically-derived subgroups of BDII-D differed in their inflammation levels and ChP volume. These findings suggest an important role of elevated peripheral inflammation and larger ChP in BDII-D.

Abstract
Although previous studies have demonstrated regional gray matter (GM) structural abnormalities in adolescents with major depressive disorder (MDD), how the topological organization of GM networks is affected in these patients is still unclear. Structural magnetic resonance imaging data were acquired from 100 first-episode drug-naïve adolescent MDD patients and 80 healthy controls (HCs). Whole-brain GM structural network was constructed for each subject, and a graph theory analysis was used to calculate the topological metrics of GM networks. Adolescent MDD patients showed significantly lower cluster coefficient and local efficiency compared to HCs. Compared to controls, adolescent MDD patients showed higher nodal centralities in the bilateral cuneus, left lingual gyrus, and right middle occipital gyrus and lower nodal centralities in the bilateral dorsolateral superior frontal gyrus, bilateral middle frontal gyrus, right anterior cingulate and paracingulate gyri, bilateral hippocampus, bilateral amygdala, bilateral caudate nucleus, and bilateral thalamus. Nodal centralities of the hippocampus were negatively associated with symptom severity and illness duration. Our findings suggest disrupted topological organization of GM structural networks in adolescent MDD patients. Impaired local segregation and abnormal nodal centralities in the prefrontal-subcortical-limbic areas and visual cortex regions may play important roles in the neurobiology of adolescent-onset MDD.

PURPOSE/OBJECTIVE(S) Radiation dermatitis is the most common complication of radiation therapy for oncology. Studies have shown that approximately 47% patients develop a second-degree or higher radiation skin reaction after radiotherapy. Although skin products that form a surface barrier such as dressings are standard of care in wound care management, they have been poorly reported in the management of radiation dermatitis. Many systemic and topical treatments have been investigated for the prevention and management of radiation dermatitis, however, how to improve this process is still needed. We hypothesize that silver sulfadiazine (SSD) dressings combined with recombinant human epidermal growth factor (EGF) may accelerate wound healing and reduce painful dressing changes. MATERIALS/METHODS Sixty patients who received radiotherapy and developed tertiary radiation dermatitis in our department from January 2019 to December 2022 were selected for the study, and were randomly divided into a control group (n = 30) and an observation group (n = 30) in a 1:1 ratio according to the inclusion criteria, both groups were first aseptically cleared with 0.9% sodium chloride injection and uniformly sprayed with recombinant human epidermal growth factor solution. In the control group, a foam dressing was used, while in the observation group, a silver sulfadiazine dressing was used to cover the wound, and in both groups, a double layer of sterile gauze was fixed on the outer layer. Wound healing time and pain level, and secondary observation endpoints were patient quality of life scores (SF-36, including physical function, psychological function, social function, daily activities, all scored on a percentage scale), patient satisfaction, and skin temperature. RESULTS The results of the control group vs. the observation group showed: wound healing time (d) of (12±5.08) vs. (8.57±3.11), p = 0.03; NRS pain score of (2.98±1.65) vs. (2.08±1.66), p = 0.04; quality of life assessment showed: psychological aspects (88.25±8.12) vs. 96.34±6.18), p = 0.0413; physical aspects (85.78±5.71) vs. (94.48±4.09), p = 0.0227; environmental aspects (90.15±3.56) vs. (98.09±1.21), p = 0.0137; satisfaction rate 28 (93.33%) vs. 30 (100.00%) , dissatisfaction rate was 2 (6.67%) vs. 0 (0.00%), p = 0.0086; skin temperature (32.08±0.79) vs. (32.14±0.43), no statistically significant difference p>0.05. CONCLUSION This randomized preliminary study showed that silver sulfadiazine dressing combined with recombinant human epidermal growth factor was significantly more effective than foam dressing in the treatment of tertiary radiation dermatitis, accelerating wound healing time, reducing patient painful dressing changes, and improving patient satisfaction.

Abstract
PURPOSE/OBJECTIVE(S) Vomiting and nausea (VN) caused by anticancer agents and/or radiation therapy (RT) can significantly affect a patient's quality of life, leading to poor compliance with further anticancer agents and/or RT. Few studies pay attention to synergistic effect of RT and concurrent highly emetogenic chemotherapy for inducing vomiting and nausea. The aim of this real-world study is to investigate the incidence of VN in patients receiving concurrent chemoradiotherapy (CCRT). MATERIALS/METHODS From June 2022 to December 2022, patients receiving concurrent chemoradiotherapy in our center were consecutively enrolled in this study. Patients received moderate and low emetic agents were excluded. The antiemesis regimens were NK1 receptor antagonist plus 5-HT3 antagonist and dexamethasone (NHD) with or without olanzapine, which were recommended by guideline of National Comprehensive Cancer Network. Acute and delayed VN were analyzed in the following stratification factors: tumor site and antiemesis regimen. Acute VN usually occurred after administration of anticancer agents and commonly resolves within the first 24 hours. Delayed VN develops in patients more than 24 hours after anticancer agent administration. The grade of VN was evaluated according to Common Terminology Criteria for Adverse Events Criteria. RESULTS A total of 312 patients were enrolled for analysis. During the CCRT period, the incidence rate of acute VN in all patients was 28.2%, the delayed VN occurred in 139 of 312 patients (44.6%). The incidence rate of acute nausea in head and neck, thorax and abdomen were 33.8%, 28.9% and 25.2%, respectively. The incidence rate of acute vomiting in head and neck, thorax and abdomen were 7.0%, 3.9% and 5.2%, respectively. The incidence rate of delayed nausea in head and neck, thorax and abdomen were 51.1%, 35.5% and 45.9%, respectively. The incidence rate of delayed vomiting in head and neck, thorax and abdomen were 14.0%, 5.3% and 9.6%, respectively. There were not significant differences between NHD regimen and NHD plus olanzapine in VN (acute nausea, 25.5% vs. 30.3%, P = 0.356; acute vomiting, 4.4% vs. 6.8%, P = 0.352; delayed nausea, 40.1% vs. 48%, P = 0.166; delayed vomiting, 8.0% vs. 10.8%, P = 0.4). Multivariate logistic regression analysis showed age <50 years (P = 0.030. HR, 95% CI: 1.893, 1.062-3.374) and history of vomiting = 0.017, HR, 95% CI: 2.249, 1.154-4.384) were risk factor for acute nausea; female (P = 0.026, HR, 95% CI: 4.254, 1.192-15.186) and sleeping time <7 hours (p = 0.049, HR, 95% CI: 3.373, 1.003-11.344) were risk factors for acute vomiting; pregnancy (P = 0.011, HR, 95% CI: 2.424, 1.228-4.783) was risk factor for delayed nausea; pregnancy = 0.013, HR, 95% CI: 3.060, 1.269-7.380) and history of vomiting = 0.020, HR, 95% CI: 2.845, 1.182-6.844) were risk factors for delayed vomiting in patients receiving CCRT. CONCLUSION CCRT still contributed high incidence of delayed nausea in patients receiving standard antiemesis regimen.

Abstract
PURPOSE/OBJECTIVE(S) Malnutrition which occurs in 90% patients with head and neck cancer (HNC) receiving concurrent chemoradiotherapy (CCRT). It may lead to inferior efficacy of antitumor treatment, increasing the adverse effects and reducing the quality of life. Several studies reported that hospital to home (H2H) standardized nutritional support management mode improved the nutritional status of patients with HNC during CCRT. However, these published studies were limited by retrospective data and small sample size. This randomized controlled study aimed to explore the improving nutritional status efficacy of H2H whole-course standardized nutritional support management mode in patients with HNC receiving CCRT. MATERIALS/METHODS From March 2021 to September 2021, patients with HNC receiving CCRT were randomly assigned into H2H nutrition management group (H2H group) and Routine nutritional management group (RTM group) in a 1:1 ratio. For H2H group, patients not only received individual nutritional management which was formulated by doctors, nutritionists and nutrition nurses from the hospital to the family at least once a week, but also received education of nutrition from network platforms. For RTM group, doctors and nurses made nutrition therapy according to nutritional status of patients. The primary endpoints of this study were nutritional status including weight, BMI, albumin, and hemoglobin. This study has been approved by the Ethics Committee of the First Affiliated Hospital of the Fourth Military Medical University (Ethics Committee Approval Number: KY20222067-F-1). RESULTS A total of 60 patients were enrolled in this study. Patient characteristics were well balanced in both arms. Compared with RTM group, patients in H2H group had better nutritional status as below: body weight (62.33±4.37) vs (60.14±4.56) kg, P = 0.037; BMI (21.84±3.01) vs (19.70±2.95) kg/m2, P = 0.033; Alb (39.25±2.17) vs (37.02±2.69) g/L, P = 0.031; Hb (132.7±9.03) vs (125.3±9.28) g/L, P = 0.039. The incidence of grade 3-4 oral mucositis in H2H group was less than RTM group (26% vs. 70%, P = 0.038). The score of quality of life was higher in H2H group compared RTM group (85.60±3.40 vs. 73.48±3.61, P = 0.000). The rate of nursing satisfaction in H2H group was higher than RTM group. Pre- and post-intervention satisfaction was 73.33% and 96.67%, respectively (p = 0.011). CONCLUSION H2H standardized nutritional support management model improve nutritional status, quality of life and rate of nursing satisfaction in patients with HNC receiving CCRT.

Abstract
PURPOSE/OBJECTIVE(S) Radiationdermatitis is one of the most common complications in patients received radiotherapy. Previous studies shown that incidence of radiation induced dermatitis (RD) is 95%. HFMEA (Healthcare Failure Mode and Effect Analysis) is a new model of nursing management. Many studies reported that HFMEA could reduce incidence of complications and adverse events, and significantly improve patient satisfaction. MATERIALS/METHODS From March 2023 to October 2022, patients received radiotherapy in our center were recruited in this study. Participants were randomly divided into control group (N = 60) and observation group (N = 60) in a ratio of 1:1. Patients in the control group were given routine skin care, health education before radiotherapy and skin care manual during radiotherapy. Based on the standard care, a HFMEA-based nursing intervention was adopted in the observation group by the following methods: Set up HFMEA care team. HFMEA team is composed of head nurses, wound specialist nurses, psychotherapists, etc. The members of the group searched the literature, case analysis and brainstorming to find out the potential failure reasons in every process of nursing radiotherapy patients in the past. Implementation of targeted measures to improve the corresponding: all patients with radiation dermatitis baseline assessment, focus on high-risk patients to shift, regular guidance medication, responsible nurses check the management of patients' skin every day to strengthen the attention of medical staff and patients' family members to radiation dermatitis. The degree of skin injury, pain and psychological status were compared between the two groups at the end of radiotherapy. RESULTS A total of 120 patients were enrolled in this study. Grade 1 RD was the most common in the observation group at the end of radiotherapy, and Grade 2 and 3 skin RD were less in the observation group than in the control group. There was not significant difference in the scores of SAS and SDS between the two groups before and after nursing (P > 0.05). In the observation group, the SAS scores (44.10±11.25 vs. 32.29 ± 7.72, P = 0.016) and SDS scores (40.98 ± 9.12 vs. 30.11 ± 5.23, P = 0.013) were significantly higher than the control group after nursing(P<0.05). The scores of SAS and SDS in the Observation Group were significantly lower than those in the control group. The scores of SAS in the Observation Group VS the control group were 32.29 ± 7.72 VS 39.09 ± 9.37 after nursing, SDS scores of Observation Group VS control group (30.11 ± 5.23 VS 38.76 ± 7.52, P<0.05). The visual analogue scale (Vas) score in the observation group was significantly lower than that in the control group (2.37 ± 0.45 VS 4.02 ± 0.53, P & Lt; 0.001), and the satisfaction degree of patients in the observation group was significantly higher than that in the control group (96.67% VS 80%, p = 0.004). CONCLUSION HFMEA model could effectively reduce incidence of RD, eliminate negative emotion, relieve pain and improve nursing satisfaction.

Abstract
Although ammonium (NH4+-N) is an important nutrient for plants, increases in soil nitrogen (N) input and atmospheric deposition have made ammonium toxicity a serious ecological problem. In this study, we explored the effects of NH4+-N stress on the ultrastructure, photosynthesis, and NH4+-N assimilation of Ottelia cordata (Wallich) Dandy, an endangered heteroblastic plant native to China. Results showed that 15 and 50 mg L-1 NH4+-N damaged leaf ultrastructure and decreased the values of maximal quantum yield (Fv/Fm), maximal fluorescence (Fm), and relative electron transport rate (rETR) in the submerged leaves of O. cordata. Furthermore, when NH4+-N was ≥ 2 mg L-1, phosphoenolpyruvate carboxylase activity (PEPC) and soluble sugar and starch contents decreased significantly. The content of dissolved oxygen in the culture water also decreased significantly. The activity of the NH4+-N assimilation enzyme glutamine synthetase (GS) significantly increased when NH4+-N was ≥ 10 mg L-1 and NADH-glutamate synthase (NADH-GOGAT) and Fd-glutamate synthase (Fd-GOGAT) increased when NH4+-N was at 50 mg L-1. However, the activity of nicotinamide adenine dinucleotide-dependent glutamate dehydrogenase (NADH-GDH) and nicotinamide adenine dinucleotide phosphate-dependent glutamate dehydrogenase (NADPH-GDH) did not change, indicating that GS/GOGAT cycle may play an important role in NH4+-N assimilation in the submerged leaves of O. cordata. These results show that short-term exposure to a high concentration of NH4+-N is toxic to O. cordata.

Abstract
BACKGROUND Anesthesia with opioids negatively affects patients' quality of recovery. Opioid-free anesthesia attempts to avoid these effects. This study aimed to evaluate the effect of opioid-free anesthesia on the quality of recovery, using lidocaine on patients undergoing hysteroscopy. METHODS A parallel-group, randomized, double-blind, controlled trial was conducted in Yichang Central Peoples' Hospital, Hubei Province, China, from January to April, 2022. We included 90 female patients (age: 18-65 years, American Society of Anesthesiologists Physical Status Class I-II) scheduled for elective hysteroscopy, 45 of whom received lidocaine (Group L), and 45 received sufentanil (Group S). Patients were randomly allocated to receive either lidocaine or sufentanil perioperatively. The primary outcome was the quality of postoperative recovery, which was assessed using the QoR-40 questionnaire (a patient-reported outcome questionnaire measuring the quality of recovery after surgery). RESULTS The two groups were similar in age, American Society of Anesthesiology physical status, height, weight, body mass index, and surgical duration. The QoR scores were significantly higher in Group L than Group S. The incidence of postoperative nausea and vomiting, as well as the time to extubation were significantly lower in Group L than Group S. CONCLUSION Opioid-free anesthesia with lidocaine achieves a better quality of recovery, faster recovery, and a shorter time to extubation than general anesthesia with sufentanil. TRIAL REGISTRATION The trial was registered on January 15, 2022 in the Chinese Clinical Trial Registry ( http://www.chictr.org.cn/showprojen.aspx?proj=149386 ), registration number ChiCTR2200055623.(15/01/2022).

Abstract
BACKGROUND Gray matter volume (GMV) alterations in several emotion-related brain areas are implicated in mood disorders, but findings have been inconsistent in adolescents with major depressive disorder (MDD) or bipolar disorder (BD). METHODS We conducted a comprehensive meta-analysis of 35 region-of-interest (ROI) and 18 whole-brain voxel-based morphometry (VBM) MRI studies in adolescent MDD and adolescent BD, and indirectly compared the results in the two groups. The effects of age, sex, and other demographic and clinical scale scores were explored using meta-regression analysis. RESULTS In the ROI meta-analysis, right putamen volume was decreased in adolescents with MDD, while bilateral amygdala volume was decreased in adolescents with BD compared to healthy controls (HC). In the whole-brain VBM meta-analysis, GMV was increased in right middle frontal gyrus and decreased in left caudate in adolescents with MDD compared to HC, while in adolescents with BD, GMV was increased in left superior frontal gyrus and decreased in limbic regions compared with HC. MDD vs BD comparison revealed volume alteration in the prefrontal-limbic system. LIMITATION Different clinical features limit the comparability of the samples, and small sample size and insufficient clinical details precluded subgroup analysis or meta-regression analyses of these variables. CONCLUSIONS Distinct patterns of GMV alterations in adolescent MDD and adolescent BD could help to differentiate these two populations and provide potential diagnostic biomarkers.

Abstract
BACKGROUND Although progress has been made in exploring postpartum depression (PPD), the involvement of cerebral structure connectivity in PPD patients keeps unclear. PURPOSE To explore structural connectivity alternations in mothers with PPD, diffusion tensor imaging (DTI) and automated fiber quantification (AFQ) were used to calculate brain white matter microstructure properties. STUDY TYPE Cross-sectional. POPULATION A total of 51 women with first-episode, treatment-näive PPD, and 49 matched healthy postpartum women (HPW) controls. FIELD STRENGTH A 3.0 T; single-shot echo-planar imaging sequence. ASSESSMENT DTI measurements of fractional anisotropy (FA), axial diffusivity (AD), radial diffusivity (RD) and mean diffusivity (MD) were obtained for 18 specific white matter tracts. The relationship between PDD symptoms, hormone levels, and postpartum days was also investigated. STATISTICAL TESTS Two sample t test and Pearson's correlation analysis. The analysis was performed by using a permutation-based multiple-comparison correction approach, with the threshold of P < 0.05 (family wise error corrected [FWE-corrected]) separately across the four different outcome measures. RESULTS Women with PPD showed significantly increased FA and AD in right anterior thalamic radiation (ATR) tract and significantly increased FA and significantly reduced RD in the cingulum tract, compared to women without PPD. The RD values of right cingulum were significantly positively correlated with postpartum days in HPW (r = 0.39). There were no significant relationships between brain measures and hormone levels in either patients or controls. DATA CONCLUSIONS DTI measures have revealed altered integrity in the white matter of the cortical-thalamic circuits in women with PPD compared to HPW. Damage to these circuits may be a structural basis for the impaired emotional regulation and blunted mother-infant bonding in mothers with PPD and a potential target for the development of new treatments. EVIDENCE LEVEL 2 TECHNICAL EFFICACY: Stage 3.

Abstract
BACKGROUND Attention deficit hyperactivity disorder (ADHD) and bipolar disorder type I (BD-Ι) share great overlapping symptoms and are highly comorbid. We aimed to compare and obtain the common and distinct gray matter volume (GMV) patterns in adult patients. METHOD We searched four databases to include whole-brain voxel-based morphometry studies and compared the GMV patterns between ADHD and healthy controls (HCs), between BD-I and HCs, and between ADHD and BD-I using anisotropic effect-size signed differential mapping software. RESULTS We included 677 ADHD and 452 BD-Ι patients. Compared with HCs, ADHD patients showed smaller GMV in the anterior cingulate cortex (ACC) and supramarginal gyrus but a larger caudate nucleus. Compared with HCs, BD-Ι patients showed smaller GMV in the orbitofrontal cortex, parahippocampal gyrus, and amygdala. No common GMV alterations were found, whereas ADHD showed the smaller ACC and larger amygdala relative to BD-Ι. Subgroup analyses revealed the larger insula in manic patients, which was positively associated with the Young Mania Rating Scale. The decreased median cingulate cortex (MCC) was positively associated with the ages in ADHD, whereas the MCC was negatively associated with the ages in BD-Ι. LIMITATIONS All included data were cross-sectional; Potential effects of medication and disease course were not analyzed due to the limited data. CONCLUSIONS ADHD showed altered GMV in the frontal-striatal frontal-parietal circuits, and BD-Ι showed altered GMV in the prefrontal-amygdala circuit. These findings could contribute to a better understanding of the neuropathology of the two disorders.

Abstract
Objective: To explore the pathological characteristics of three mice models of temporomandibular joint degenerative joint disease (TMJDJD), including osteoarthritis and osteoarthrosis, and to provide references for animal experimental study regarding the pathological mechanism of osteoarthritis and osteoarthrosis. Methods: A total of 54 8-week-old male C57BL/6 mice were selected to construct three TMJDJD animal models, including bilateral temporomandibular joint (TMJ) Freund's complete adjuvant (FCA) injection model, bilateral TMJ monosodium iodoacetate (MIA) injection model, and right TMJ discectomy model. FCA injection model (15 mice) was divided into saline injection group, FCA injection group-1 week, FCA injection group-2 week, FCA injection group-4 week and FCA injection group-6 week, 3 mice were used at each time point, with a total of 6 TMJs on both sides. MIA injection model (15 mice) was separated into saline injection group, MIA injection group-1 week, MIA injection group-2 week, MIA injection group-4 week and MIA injection group-6 week, 3 mice were used at each time point, with a total of 6 TMJs on both sides. TMJ discectomy model (24 mice) was split into control group, discectomy group-2 week group, discectomy group-4 week and discectomy group-6 week, six mice were used at each time point, with a total of six right TMJs. General pictures of the bilateral joints area of mice were collected 1 day after drug injection, and stereoscopic images of condylar tissues were collected 4 weeks after microsurgery for discectomy. Mouse TMJ tissue sections from each time point were stained with HE and toluidine blue, respectively, synovial tissues were scored for synovial inflammation, and the percentage of proteoglycan in condylar cartilage was quantitatively analyzed. Results: One day after intra-articular FCA or MIA injection, the width of bilateral TMJ were significantly increased in FCA injection groups [(24.60±0.46) mm] compared with the saline injection group [(21.63±0.52) mm] (t=4.25, P<0.013), the width of bilateral TMJ in MIA injection groups [(24.50±0.62) mm] were also significantly higher than that in saline injection group [(21.40±0.52) mm] (t=3.82, P=0.019). The synovitis scores in FCA injection groups 1, 2, 4, 6 weeks after FCA injection were significantly higher than that of the saline injection group (F=18.09, P<0.001), with the proteoglycan of condylar cartilage increased firstly and then decreased compared with the saline injection group (F=21.59, P<0.001). Condylar cartilage proteoglycan loss in different degrees were observed 1, 2, 4 and 6 weeks after MIA injection (F=13.59, P<0.001), and synovitis scores were increased at different degrees compared with saline injection group (F=14.79, P<0.001). The morphology of condylar cartilage in discectomy groups mice were severely damaged, synovial tissues showed dense connective tissue lesions at 2, 4 and 6 weeks postoperatively, condylar cartilage tissues showed a time-dependent loss of proteoglycan compared with the control group (F=40.62, P<0.001). Conclusions: Intra-articular FCA injection establishes a mouse model of TMJ osteoarthritis with severe synovial inflammation. Intra-articular MIA injection constructs a mouse model of typical TMJ osteoarthritis. Discectomy establishes a mouse TMJ osteoarthrosis model with severe condylar cartilage destruction.

Abstract
BACKGROUND AND AIMS Perfectionism is correlated with the occurrence of exercise dependence. We aim to reveal the role of functional connectivity (FC) between gray matter (GM) and white matter (WM) networks in the association between perfectionism and exercise dependence. METHODS In this cross-sectional study, one hundred ten participants with exercise dependence underwent behavioral evaluation and resting-state functional magnetic resonance imaging. Perfectionism and exercise dependence were quantified using the Frost Multidimensional Perfectionism Scale (FMPS) and Exercise Dependence Scale (EDS). We used a K-means clustering algorithm to identify functional GM and WM networks and obtained the FCs of the GM-GM, GM-WM, and WM-WM networks. Partial correlation and mediation analyses were performed to explore the relationships among FCs, FMPS, and EDS. RESULTS We identified ten stable GM networks and nine WM networks. Of these, FCs existed between the corona radiata network (WM1) and default mode network (DMN, GM8), WM1 network and WM DMN (WM4), WM1 network and midbrain WM network (WM7), and WM4 network and inferior longitudinal fasciculus network (WM9). The WM1-GM8 and WM1-WM4 FCs were positively correlated with the EDS and negative FMPS. The mediating effects of the WM1-GM8 and WM1-WM4 FCs were established in the association between the negative dimensional FMPS and EDS. DISCUSSION AND CONCLUSIONS The WM1 network anatomically linked the subregions within the GM8 and WM4 networks, and WM1-GM8 and WM1-WM4 FCs mediated the association between negative dimensional FMPS and EDS. These findings indicated that DMN function might be involved in the increased risks of exercise dependence promoted by negative perfectionism.

Abstract
Temporomandibular joint degenerative disease is a common disease in the temporomandibular joint disorders, including osteoarthrosis and osteoarthritis. There were often confused in clinical diagnosis, treatment and basic research both of osteoarthrosis and osteoarthritis. That will affect the choice of clinicians and scientists to the treatment of disease, the judgment of prognosis, and the experimental results. The key to distinguishing the clinical significance of osteoarthrosis and osteoarthritis in temporomandibular degenerative disease lies in how to correctly recognize the main differences between the two, that is, whether there is pain in the temporomandibular joint and the masticatory muscle area. At the same time, it is necessary to judge the course of the disease, whether the two are transforming each other and the clinical significance of other dentistry.

Abstract
Objective: To investigate the effects of Streptococcus pneumoniae (Spn) colonization and the change of upper airway microbiome on the clinical manifestations in children with respiratory syncytial virus (RSV) infection. Methods: A retrospective cohort included 508 RSV-infected children with pneumonia and hospitalized in Respiratory Department of Children's Hospital of Chongqing Medical University from July 2009 to July 2018. A total of 508 cases of RSV-infected children (RSV non-sequencing group) were divided into 2 groups: children with Spn airway colonization (RSV+Spn group) and children without with Spn airway colonization (RSV group) according to the detection for virus and bacteria in nasopharyngeal aspirate, and these 2 groups were compared in terms of clinical manifestations by chi-square test in different age groups. In addition, in RSV pandemic season from November 2018 to February 2020, nasopharyngeal aspirates were collected from 20 children hospitalized in Respiratory Department of Children's Hospital of Chongqing Medical University and infected with RSV but without any positive detection of bacteria (RSV 16 S-sequencing group) and from children undergoing surgery without any sign of respiratory infection (control group). The difference of microbiome detected by 16 S RNA sequencing was compared using rank sum test between RSV 16 S-sequencing group and control group, and also between children with severe and mild pneumonia in RSV 16 S-sequencing group. Results: A total of 508 RSV non-sequencing group included 346 males and 162 females, and the visiting age was 6 (2, 12) months. RSV group included 443 cases and RSV+Spn group included 65 cases. In the study 244 cases were aged <6 months and 264 cases were aged ≥6 months. In children aged ≥6 months of RSV non-sequencing group, the proportion of cases presenting fever over 38 ℃ and cases with severe pneumonia in RSV+Spn group were higher than those in RSV group (53.2% (25/47) vs. 34.6% (72/217), 38.3% (18/47) vs. 21.2% (46/217), χ²=5.70,6.15, both P<0.05). RSV 16 S-sequencing group included 16 males and 4 females and the visiting age was 3.0 (1.9, 8.0) months. Airway microbiome diversity in RSV 16 S-sequencing group was lower than that in control group (alpha index: 0.93 (0.42, 2.51) vs. 3.05 (2.88, 3.61), U=60.00, P=0.001). Conclusions: RSV infection is associated with the changes of the upper airway microbiome. When the balance of airway microbiome is broken and the presence of the dominant colonization of Spn follows, it may aggravate the severity of RSV infection in children aged ≥6 months.

Abstract
Temporomandibular joint osteoarthritis (TMJOA) is a common degenerative joint disease without effective intervention strategies. Previous research implied that alpha-kinase 1 (ALPK1) is involved in the inflammatory responses of gout, a chronic arthritis. Herein, we found the main distribution of ALPK1 in a proliferative layer of condylar cartilage and marrow cavity of subchondral bone, as well as a lining layer of synovial tissues in human temporomandibular joint. Moreover, the expression of ALPK1 was augmented in degraded condylar cartilage of monosodium iodoacetate (MIA)-induced TMJOA mice. After MIA induction, ALPK1 knockout mice exhibited attenuated damage of cartilage and subchondral bone, as well as synovitis, as compared with wide type mice. In contrast, intra-articular administration of recombinant human ALPK1 aggravated the pathology of MIA-induced TMJOA. Furthermore, ex vivo study demonstrated that ALPK1 exacerbated chondrocyte catabolism by upregulating matrix metalloproteinase 13 and cyclooxygenase 2 by activating NF-κB (nuclear factor-kappaB) signaling and suppressed anabolism by downregulating aggrecan by inhibiting ERK1/2 (extracellular signal-regulated kinase 1/2) in articular chondrocytes. Taken together, ALPK1 exacerbates the degradation of condylar cartilage during TMJOA through the NF-κB and ERK1/2 signaling pathway. This study provides a new insight regarding the role of ALPK1 during TMJOA pathology.

And to provide a reference to establish personalized diagnosis and treatment plans for TMD patients so as to prevent TMD and reduce predisposing factors. Methods: A total of 141 TMD patients, who were admitted in the Department of Oral and Maxillofacial Surgery in School and Hospital of Stomatology, Wuhan University from October 2018 to February 2021 were selected. There were 121 females and 20 males, with an average age of 30 years. A total of 90 healthy people were included as controls. A full-time psychologist conducted relevant questionnaire surveys. The questionnaires include general clinical survey forms and TMD symptom questionnaire. In addition, Axis Ⅱ assessment instruments include graded chronic pain scale, jaw functional limitation scale, oral behaviors checklist, patient health questionnaire-9 (depression), generalized anxiety disorder scale, patient health questionnaire-15 (physical symptoms), etc. The main observational indicators include: pain level, pain impact rates, overall classification of chronic pain, limited chewing function score, limited motor function score, limited communication function score, total jaw function restricted score, depression score, anxiety score, somatic symptom score and oral behavior score.The survey data were imported into SPSS 22.0 software for statistical analysis. Results: In the TMD group 60.3% (85/141) patients had various degrees of pain, 24.1% (34/141) of those with pain effect grades from 1 to 3 and 61.0% (86/141) showed chronic pain overall grades from Ⅰ to Ⅳ. The chewing function restricted score was 2.67(1.17, 4.25), motor function restricted score was 4.25(1.75, 6.12), communication function restricted score was 1.13(1.00, 2.25) and total jaw function restricted score was 2.56(1.47, 4.15) respectively. Patients with mild depression or above accounted for 59.6%(84/141), patients with mild anxiety or above accounted for 56.7%(80/141), 46.1%(65/141) patients had somatization symptoms. Statistical differences (P<0.05) were determined between TMD group and control group in various scores of jaw function, oral behavior grading, depression, anxiety, and physical symptoms. Physical symptoms had significantly statistical difference between different diagnostic classification(P<0.05). Meanwhile, among the different chronic pain levels in the TMD group, there were statistical differences in the various scales of mandibular dysfunction, depression, anxiety, and somatization. In the TMD group, other significant differences were noticed between males and females in terms of the average score of mouth opening, verbal and facial communication, the total score of mandibular dysfunction as well as physical symptoms (P<0.05). Conclusions: Compared with the healthy people, patients with TMD had more abnormal oral behaviors, different restriction of the mandibular functional activities. At the same time, depression, anxiety, and somatization were more serious. Patients with osteoarthritis and subluxation of temporomandibular joint were more likely to suffer physical symptoms. TMD patients suffering from pain had more severe mandibular dysfunction and symptoms of depression, anxiety, and somatization.

Abstract
Lipoic acid (LA) is an endogenous antioxidant that exists widely in nature. Supplementation with LA is a promising approach to improve the outcomes of patients with multiple sclerosis (MS). This systematic review aimed to provide a comprehensive overview of both in vitro and in vivo studies describing the pharmacokinetics, efficacy, safety, and mechanism of LA in MS‐related experiments and clinical trials. A total of 516 records were identified by searching five databases, including PubMed, Web of Science, Embase, Scopus, and Cochrane Library. Overall, we included 20 studies reporting LA effects in cell and mouse models of MS and 12 studies reporting LA effects in patients with MS. Briefly, cell experiments revealed that LA protected neurons by inhibiting the expression of inflammatory mediators and activities of immune cells. Experimental autoimmune encephalomyelitis mouse experiments demonstrated that LA consistently reduced the number of infiltrating immune cells in the central nervous system and decreased the clinical disability scores. Patients with MS showed relatively stable Expanded Disability Status Scale scores and better walking performance with few adverse events after the oral administration of LA. Notably, heterogeneity of this evidence existed among modeling methods, LA usage, MS stage, and trial duration. In conclusion, this review provides evidence for the anti‐inflammatory and antioxidative effects of LA in both in vitro and in vivo experiments; therefore, patients with MS may benefit from LA administration. Whether LA can be a routine supplementary therapy warrants further study.

Abstract
Temporomandibular joint osteoarthritis (TMJOA) is one of the most common diseases causing chronic pain in the oral and maxillofacial region. So far, there are few ways to relieve the pain of TMJOA. Melatonin (MT) has a good analgesic effect in many diseases, including fibromyalgia, neuropathic pain, chronic headache, and burn pain, with very low acute toxicity and side effects. This study was to investigate the role and mechanism of MT in TMJOA chronic pain. In rats TMJOA chronic pain occurred at day 14 after an intra-temporomandibular joint injection of monosodium iodoacetate, which we previously reported. The enzyme-linked immunosorbent assay results showed that MT levels were higher in the synovial fluid from patients and rats with TMJOA as compared with those from control. Fluorescent retrograde tracing (Dil) identified that upregulation of MT type 2 receptor (MT2R) in trigeminal ganglion (TG) neurons innervating rat temporomandibular joints was accompanied by TMJOA chronic pain. Nociceptive behavior as assessed by von Frey and the Rat Grimace Scale demonstrated that exogenous administration of MT relieved chronic pain in TMJOA rats, whereas blocking MT2R with 4P-PDOT reversed the analgesic effect of MT. Immunofluorescence analysis also confirmed that MT inhibited CGRP and IB4 expression of TG neurons, and this inhibition was reversed by administering the MT2R antagonist in TMJOA rats. By using Fluo-3 AM-based calcium imaging in vitro, MT elicited calcium transients in Dil+ TG neurons, which were significantly abolished by 4P-PDOT. Collectively, this study suggested that MT relieves the TMJOA chronic pain of rats through downregulation of sensitized CGRP+ and IB4+ neurons in TG via MT2R. This will be helpful for health care professionals utilizing MT as an option against TMJOA chronic pain.

Abstract
The relapse rate for children with acute myeloid leukemia is nearly 40% despite aggressive chemotherapy and often stem cell transplant. We sought to understand how environment-induced signaling responses are associated with clinical response to treatment. We previously reported that patients whose AML cells showed low G-CSF-induced STAT3 activation had inferior event-free survival compared to patients with stronger STAT3 responses. Here, we expanded the paradigm to evaluate multiple signaling parameters induced by a more physiological stimulus. We measured STAT3, STAT5 and ERK1/2 responses to G-CSF and to stromal cell-conditioned medium for 113 patients enrolled on COG trials AAML03P1 and AAML0531. Low inducible STAT3 activity was independently associated with inferior event-free survival in multivariate analyses. For inducible STAT5 activity, those with the lowest and highest responses had inferior event-free survival, compared to patients with intermediate STAT5 responses. Using existing RNA-sequencing data, we compared gene expression profiles for patients with low inducible STAT3/5 activation with those for patients with higher inducible STAT3/5 signaling. Genes encoding hematopoietic factors and mitochondrial respiratory chain subunits were overexpressed in the low STAT3/5 response groups, implicating inflammatory and metabolic pathways as potential mechanisms of chemotherapy resistance. We validated the prognostic relevance of individual genes from the low STAT3/5 response signature in a large independent cohort of pediatric AML patients. These findings provide novel insights into interactions between AML cells and the microenvironment that are associated with treatment failure and could be targeted for therapeutic interventions.

Abstract
BACKGROUND COVID-19 is a new pneumonia. It has been hypothesized that tobacco smoking history may increase severity of this disease in the patients once infected by the underlying coronavirus SARS-CoV-2 because smoking and COVID-19 both cause lung damage. However, this hypothesis has not been tested. OBJECTIVE Current study was designed to focus on smoking history in patients with COVID-19 and test this hypothesis that tobacco smoking history increases risk for severe COVID-19 by damaging the lungs. METHODS AND RESULTS This was a single-site, retrospective case series study of clinical associations, between epidemiological findings and clinical manifestations, radiographical or laboratory results. In our well-characterized cohort of 954 patients including 56 with tobacco smoking history, smoking history increased the risk for severe COVID-19 with an odds ratio (OR) of 5.5 (95% CI: 3.1-9.9; P = 7.3 × 10-8 ). Meta-analysis of ten cohorts for 2891 patients together obtained an OR of 2.5 (95% CI: 1.9-3.3; P < 0.00001). Semi-quantitative analysis of lung images for each of five lobes revealed a significant difference in neither lung damage at first examination nor dynamics of the lung damage at different time-points of examinations between the smoking and nonsmoking groups. No significant differences were found either in laboratory results including D-dimer and C-reactive protein levels except different covariances for density of the immune cells lymphocyte (P = 3.8 × 10-64 ) and neutrophil (P = 3.9 × 10-46 ). CONCLUSION Tobacco smoking history increases the risk for great severity of COVID-19 but this risk is achieved unlikely by affecting the lungs.

Abstract
STUDY OBJECTIVES Unobtrusive monitoring of sleep and sleep disorders in children presents challenges. We investigated the possibility of using Ultra-Wide band (UWB) radar to measure sleep in children. METHODS Thirty-two children scheduled to undergo a clinical polysomnography participated; their ages ranged from 2 months to 14 years. During the polysomnography, the children's body movements and breathing rate were measured by an UWB-radar. A total of 38 features were calculated from the motion signals and breathing rate obtained from the raw radar signals. Adaptive boosting was used as machine learning classifier to estimate sleep stages, with polysomnography as gold standard method for comparison. RESULTS Data of all participants combined, this study achieved a Cohen's Kappa coefficient of 0.67 and an overall accuracy of 89.8% for wake and sleep classification, a Kappa of 0.47 and an accuracy of 72.9% for wake, rapid-eye-movement (REM) sleep, and non-REM sleep classification, and a Kappa of 0.43 and an accuracy of 58.0% for wake, REM sleep, light sleep and deep sleep classification. CONCLUSION Although the current performance is not sufficient for clinical use yet, UWB radar is a promising method for non-contact sleep analysis in children.

Abstract
BACKGROUND The paradox of similar diagnostic criteria but potentially different neuropathologies in panic disorder (PD) and social anxiety disorder (SAD) needs to be clarified. METHODS We performed a qualitative systematic review and a quantitative whole-brain voxel-based morphometry (VBM) meta-analysis with an anisotropic effect-size version of seed-based D mapping (AES-SDM) to explore whether the alterations of grey matter volume (GMV) in PD are similar to or different from those in SAD, together with potential confounding factors. RESULTS A total of thirty-one studies were eligible for inclusion, eighteen of which were included in the meta-analysis. Compared to the respective healthy controls (HC), qualitative and quantitative analyses revealed smaller cortical-subcortical GMVs in PD patients in brain areas including the prefrontal and temporal-parietal cortices, striatum, thalamus and brainstem, predominantly right-lateralized regions, and larger GMVs in the prefrontal and temporal-parietal-occipital cortices, and smaller striatum and thalamus in SAD patients. Quantitatively, the right inferior frontal gyrus (IFG) deficit was specifically implicated in PD patients, whereas left striatum-thalamus deficits were specific to SAD patients, without shared GMV alterations in both disorders. Sex, the severity of clinical symptoms, psychiatric comorbidity, and concomitant medication use were negatively correlated with smaller regional GMV alterations in PD patients. CONCLUSION PD and SAD may represent different anxiety sub-entities at the neuroanatomical phenotypes level, with different specific neurostructural deficits in the right IFG of PD patients, and the left striatum and thalamus of SAD patients. This combination of differences and specificities can potentially be used to guide the development of diagnostic biomarkers for these disorders.

Abstract
Objective: This study aims to investigate the significant alterations in brain white matter integrity in individuals with bipolar disorder (BD) who had attempted suicide by applying a tract-based spatial statistics (TBSS) approach with tensor-based spatial normalization. Methods: A TBSS approach with novel tensor-based registration was used to compare the white matter fractional anisotropy (FA) between 51 individuals with BD, of whom 19 had attempted suicide, and 43 healthy controls (HC). The suicide attempt was assessed with the Columbia-Suicide Severity Rating Scale (C-SSRS). In addition, we also investigated the correlations of FA values with clinical measures in BD, including illness duration, and the severity of depression and anxiety measured by the Hamilton Depression Rating Scale (HAMD) and Hamilton Anxiety Rating Scale (HAMA), respectively. Results: A significant reduction of FA value in the hippocampal cingulum was observed in BD individuals who had attempted suicide compared with those who had not. For the genu/body of the corpus callosum, inferior fronto-occipital fasciculus, uncinate fasciculus, and anterior thalamic radiation, the reductions in FA values were significantly greater in both BD subgroups who attempted suicide and who did not, compared to HC. The correlation analysis showed that the illness duration of attempters was correlated to the FA value of the genu of the corpus callosum, while the HAMD and HAMA scores of non-attempters were relevant to the FA of the superior longitudinal fasciculus. Conclusion: The observation that white matter integrity was altered in the hippocampal cingulum in BD individuals who attempted suicide suggested that this brain area may be the neurobiological basis of suicide attempts. Our findings also support the involvement of white matter (WM) microstructure of frontal-subcortical circuits in the neurobiological mechanism of BD. In addition, the illness duration of patients with attempted suicide may have an effect on the altered integrity of the corpus callosum.

Abstract
Background Background activity on fluorine-18-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) is often used as a reference to assess a patient's response to tumor treatment. To produce a suitable background activity reference, we examined the variations in standardized uptake values (SUVs) in the blood pool and liver of a large multi-aged population. Methods A total of 2,526 subjects underwent 18F-FDG PET/CT examinations and were divided into 12 age groups. Pearson's partial correlation and multivariate regression analyses were performed to assess the associations between individual factors and SUVs of the blood pool and liver and to identify the factor that most influenced the SUVs. The mean SUVs across the age groups were also determined. Results Positive correlations were found between individual factors and SUVs. Age appeared to be the most important predictor of SUVs and was significantly associated with the blood pool SUVmax (ß=0.466, P=0.000), blood pool SUVmean (ß=0.393, P=0.000), liver SUVmax (ß=0.347, P=0.000), and liver SUVmean (ß=0.354, P=0.000). Blood pool and liver SUVs rose rapidly until the age of 20 and then showed a slow upward trend without reaching a plateau. Conclusions Age is an important factor that influences variations in the blood pool and liver SUVs. Our study clarified this understanding of age-related variations in SUVs and provided a normal range of blood pool and liver SUVs that may aid clinicians in evaluating tumors with greater accuracy.

Abstract
OBJECTIVE The maturation of neural network-based techniques in combination with the availability of large sleep datasets has increased the interest in alternative methods of sleep monitoring. For unobtrusive sleep staging, the most promising algorithms are based on heart rate variability computed from inter-beat intervals (IBIs) derived from ECG-data. The practical application of these algorithms is even more promising when alternative ways of obtaining IBIs, such as wrist-worn photoplethysmography (PPG) can be used. However, studies validating sleep staging algorithms directly on PPG-based data are limited. RESULTS We applied an automatic sleep staging algorithm trained and validated on ECG-data directly on inter-beat intervals derived from a wrist-worn PPG sensor, in 389 polysomnographic recordings of patients with a variety of sleep disorders. While the algorithm reached moderate agreement with gold standard polysomnography, the performance was significantly lower when applied on PPG- versus ECG-derived heart rate variability data (kappa 0.56 versus 0.60, p < 0.001; accuracy 73.0% versus 75.9% p < 0.001). These results show that direct application of an algorithm on a different source of data may negatively affect performance. Algorithms need to be validated using each data source and re-training should be considered whenever possible.

Abstract
Objective: To evaluate the MRI and cone beam CT (CBCT) image registration methods of the temporomandibular joint (TMJ), and to explore the clinical application of the registered images and clinical diagnostic data for examining the relationship between the articular disc and condyle. Methods: Three patients with TMJ disc disposition were recruited at the Department of Oral and Maxillofacial Surgery, School of Stomatology, Wuhan University from January to March 2018. One patient was male, aged 30, and the others were females, aged 21 and 26 respectively. Three-dimensional (3D) images of CBCT and MRI of the TMJ were reconstructed and registered by using Mimics software. The images were then evaluated after the registration. The evaluation indicators selected were the area and volume of the articular disc, the position of the articular disc or the distance between the highest point of the condyle (point C) to the center point of the articular disc (point D), the distance between the last point of the joint disc (point P) to point C, as well as the angle between line CD and FH plane (∠DCF) at either opened- or closed-mouth condition. Results: The registration images of TMJ, at the closed- and opened-mouth positions of the 3 patients, showed the anatomical structures and interrelationships of the articular disc, articular nodules, joint fossa and condyle. Combined with clinical diagnosis, the difference of CD distances at the normal articular disc position was the minimum (1.94 mm), the difference of CD distances was small at the anterior disc displacement with non-reduction and larger with reduction. When the joint disc was in the opened-mouth position, ∠DCF angle was minimal (3.81°). The patients with anterior disc displacement with non-reduction showed the largest ∠DCF angle (48.03°). Conclusions: The position of the articular disc relative to the condyle and articular nodules, either at closed- or opened-mouth conditionds, could be accurately displayed after the image registration and fusion. The registration image not only could fully show the shape and position of the articular disc in different status from a 3D perspective, but also might provide basis for clinical study of TMJ disc displacement.

Abstract
Patterns of change in whole-brain functional networks remain poorly understood in patients with end-stage renal disease (ESRD) undergoing hemodialysis (HD). We conducted a prospective research to investigate the topological properties of whole-brain functional networks in those patients using a graph-based network analysis. Resting-state functional magnetic resonance imaging was performed on 51 ESRD patients (25 HD and 26 nondialysis patients) and 36 healthy controls (HCs). We compared the topological properties of brain functional networks among the three groups, and analyzed the relationships between those significant parameters and clinical variables in ESRD patients. Progressively disrupted global topological organizations were observed from nondialysis patients to HD patients compared with HCs (all p < 0.05 after Bonferroni correction). HD patients, relative to HCs, showed significantly decreased nodal centralities in the left temporal pole: superior temporal gyrus, bilateral median cingulate and paracingulate gyri, bilateral hippocampus, bilateral parahippocampal gyrus, and bilateral amygdala, and showed increased nodal centralities in the orbital part of the bilateral middle frontal gyrus, left cuneus, and left superior occipital gyrus (all p < 0.05 after Bonferroni correction). Furthermore, nodal centralities in the bilateral hippocampus were significantly decreased in HD patients compared with nondialysis patients (p < 0.05 after Bonferroni correction). Dialysis duration negatively correlated with global efficiency in ESRD patients undergoing HD (r = -0.676, FDR q = 0.004). This study indicates that ESRD patients exhibit disruptions in brain functional networks, which are more severe in HD patients, and these alterations are correlated with cognitive performance and clinical markers.

Abstract
Our purpose was to measure the temporomandibular joint (TMJ) synovial fluid (SF) levels of vascular endothelial growth factor (VEGF) and fibroblast growth factor-2 (FGF-2) before and after intra-articular injection of hyaluronic acid (HA) and to investigate the possible mechanism involved in the therapeutic value of HA. We analysed the synovial fluid of 30 patients with unilateral internal derangement (ID) or osteoarthritis (OA) of the TMJ (confirmed by magnetic resonance imaging and cone-beam computed tomography) and recorded clinical signs and symptoms including maximal mouth opening, subjective joint pain, and joint noise at the patient's each visit. All clinical signs significantly improved after injection of HA, and there was no significant difference between ID and OA groups. In synovial fluid parameters, the concentration of VEGF was significantly higher before treatment with HA than after treatment, but there was no significant difference in the concentration of FGF-2 between before and after treatment. The study findings suggest intra-articular injection of HA may reduce the synovitis and improve the internal state of the TMJ in a short period.

Abstract
Vibration exercise (VE) has been suggested for effective muscle training and conditioning. Surface electromyogram (EMG) is employed as a powerful tool for the analysis of VE. However, sharp peaks are observed in the EMG spectrum. The interpretation of these peaks is controversial, complicating the extraction of EMG parameters for VE analysis. The present study is therefore aiming at quantifying the relevance of these spectral peaks in EMG recording during VE. To this end, surface EMG was recorded on the biceps brachii during VE at different amplitudes and frequencies. The power percentage contained in the two narrow bands (±0.5 Hz) around the vibration frequency and its first harmonic (PPv) was calculated. The root mean square (RMS) value of the EMG was calculated with and without including the spectral peaks and then compared. The results show an average PPv value of 20.7 ± 7.9 % and a relative RMS difference (∆RMS) of 12.2 ± 3.8 %. In PPv and addition, RMS∆ seem to be influenced by vibration amplitude and frequency. Our results provide useful information for the analysis of VE and contribute to better understanding of the EMG spectral peaks.

Abstract
BACKGROUND The differences and relationships between stimulus-related brain activation for sexually preferred stimuli and sexually nonpreferred stimuli are still unclear. AIM This study aimed to identify brain regions that were mostly associated with sexual stimuli. METHODS We used the activation likelihood estimation, meta-analytic connectivity modelling, and behavioral domain metadata in the BrainMap database to perform this analysis. OUTCOMES We found convergent activation foci and created a model for the extended brain network involved in responses to sexual stimuli and also assessed the functional properties of these regions. RESULTS A total of 34 experiments from 15 studies including 368 subjects and 343 foci were analyzed. The results showed that sexual stimuli are related to the extensive activation of the occipital-temporal-limbic system and less extensive activation of the basal ganglia. Sexually preferred stimuli activated mainly the anterior cingulate cortex and right fusiform gyrus, while sexually nonpreferred stimuli activated the limbic system, occipital gyrus, and thalamus. CLINICAL IMPLICATIONS To have a further understanding of the central mechanisms of human sexuality. STRENGTHS & LIMITATIONS Patient characteristics and analysis techniques in the included studies were heterogeneous. CONCLUSIONS These findings suggest that the anterior cingulate cortex is an important cognitive control area for both sexually preferred and nonpreferred stimuli. Meta-analytic connectivity modelling analysis revealed a network of the core brain areas involved in response to sexual stimuli, and behavioral domain analysis indicated that these areas have both common and discrete functional properties.

Abstract
OBJECTIVES Impaired intestinal barrier function has been demonstrated in the pathophysiology of diarrhea-predominant irritable bowel syndrome (IBS-D). This study aimed to describe the intestinal ultrastructural findings in the intestinal mucosal layer of IBS-D patients. METHODS In total, 10 healthy controls and 10 IBS-D patients were analyzed in this study. The mucosa of each patient's rectosigmoid colon was first assessed by confocal laser endomicroscopy (CLE); next, biopsied specimens of these sites were obtained. Intestinal tissues of IBS-D patients and healthy volunteers were examined to observe cellular changes by transmission electron microscopy (TEM). RESULTS CLE showed no visible epithelial damage or inflammatory changes in the colonic mucosa of IBS-D compared with healthy volunteers. On transmission electron microscopic examination, patients with IBS-D displayed a larger apical intercellular distance with a higher proportion of dilated (>20 nm) intercellular junctional complexes, which was indicative of impaired mucosal integrity. In addition, microvillus exfoliation, extracellular vesicle as well as increased presence of multivesicular bodies were visible in IBS-D patients. Single epithelial cells appeared necrotic, as characterized by cytoplasmic vacuolization, cytoplasmic swelling, and presence of autolysosome. A significant association between bowel habit, frequency of abdominal pain, and enlarged intercellular distance was found. CONCLUSION This study showed ultrastructural alterations in the architecture of intestinal epithelial cells and intercellular junctional complexes in IBS-D patients, potentially representing a pathophysiological mechanism in IBS-D.

Abstract
BACKGROUND AND PURPOSE Previous studies have shown perfusion abnormalities in the thalamus and upper brain stem in patients with epilepsy with impaired consciousness. We hypothesized that these areas associated with consciousness will also show metabolic abnormalities. However, metabolic abnormalities in those areas correlated with consciousness has not been characterized with multiple-voxel 1H-MRS. In this study, we investigated the metabolic alterations in these brain regions and assessed the correlation between seizure features and metabolic alterations. MATERIALS AND METHODS Fifty-seven patients with epilepsy and 24 control subjects underwent routine MR imaging and 3D multiple-voxel 1H-MRS. Patients were divided into 3 subgroups: focal impaired awareness seizures (n = 18), primary generalized tonic-clonic seizures (n = 19), and secondary generalized tonic-clonic seizures (n = 20). The measured metabolite alterations in NAA/Cr, NAA/(Cr + Cho), and Cho/Cr ratios in brain regions associated with the consciousness network were compared between the patient and control groups. ROIs were placed in the bilateral inferior frontal gyrus, supramarginal gyrus, cingulate gyrus, precuneus, thalamus, and upper brain stem. Correlations between clinical parameters (epilepsy duration and seizure frequency) and metabolite alterations were analyzed. RESULTS Significantly lower NAA/Cr and NAA/(Cho + Cr) ratios (P < .05 and < .01, respectively) were observed in the bilateral thalamus and upper brain stem in all experimental groups, and significantly high Cho/Cr ratios (P < .05) were observed in the right thalamus in the focal impaired awareness seizures group. There were no significant differences in metabolite ratios among the 3 patient groups (P > .05). The secondary generalized tonic-clonic seizures group showed a negative correlation between the duration of epilepsy and the NAA/(Cr + Cho) ratio in the bilateral thalamus (P < .05). CONCLUSIONS Metabolic alterations were observed in the brain stem and thalamus in patients with epilepsy with impaired consciousness.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Fritillaria cirrhosa D. Don bulbs contain alkaloids and are one of the most intensively exploited alpine Himalayan medicinal species. In terms of proprietary medicines, our study shows that 210 F. cirrhosa products are offered by 46 suppliers, most of which (44) are situated in China and two in Nepal. A widespread commercial use is as one of the main ingredients in cough syrups. A well known example is "Nin Jiom Pei Pa Koa Herbal Cough & Throat Syrup", which typically contains more F. cirrhosa than any other herbal ingredient in the formulation. The biggest market for F. cirrhosa bulbs is China, where demand exceeds supply of this wild harvested species for use in traditional Chinese medicine (TCM). Cross-border trade from Nepal to China occurs in significant quantities. Bhutan also imports F. cirrhosa bulbs from Nepal. In addition, F. cirrhosa is registered as an active ingredient in traditional herbal medicinal preparations in Australia, Canada, Hong Kong SAR, Malaysia, Republic of Korea, Singapore and Taiwan. There is also an export trade in F. cirrhosa to Europe. Assessing how much F. cirrhosa is traded is complex, however, due to a "look-alike" challenge, as nine Chinese Fritillaria species are traded in Europe (Fritillaria cirrhosa, F. delavayi, F. hupehensis, F. pallidiflora, F. przewalskii, F. thunbergii, F. unibracteata, F. ussuriensis and F. walujewii). AIMS OF THE STUDY The aims of this review were to assess the scale of the global trade in F. cirrhosa, and to synthesise studies of the impacts of wild harvest on F. cirrhosa populations and on the extent of emerging cultivation initiatives as an alternative to wild harvest. METHODS Firstly, we reviewed published information on studies on impacts of wild F. cirrhosa harvest from across the geographic range of this species. Secondly, global trade data for F. cirrhosa were analysed. RESULTS The principal demand for F. cirrhosa bulbs is in China, where hundreds of different companies produce Fritillaria preparations. Trade data also show that in 2013, China exported over 44 tonnes of F. cirrhosa bulbs to Taiwan and 26.7 tonnes to the Republic of Korea. Extensive commercial use and limited wild stocks result in a high price (2000 - 3800 CNY per kg (around US$ 303 -560 per kg in 2017)) for F. cirrhosa bulbs. Prices of cultivated Fritillaria bulbs are much lower (600-680 CNY per kg in 2017) than wild harvested bulbs. But due to very specific growth requirements of F. cirrhosa, cultivation is not yet able to meet total demand. The consequence is continued exploitation of wild stocks. At the same time, however, an increasing proportion of the demand is met by cultivation of alternative Fritillaria species that are easier to grow than F. cirrhosa. The air-dry mass of F. cirrhosa bulbs varies between 0.0917 and 0.1116 g per bulb. This represents 8960 - 10,900 bulbs/kg or 8.9 - 10.9 million bulbs per tonne. Current demand therefore represents billions of bulbs per year. CONCLUSIONS Demand for F. cirrhosa bulbs, particularly from China, makes this species one of the most intensively harvested alpine Himalayan medicinal bulbs. Although F. cirrhosa is listed as a Class III protected species in China, billions of these tiny, wild harvested bulbs are sold per year. Due to demand exceeding supply, the price of F. cirrhosa bulbs has increased dramatically. Between 2002 and 2017, for example, the price of wild harvested F. cirrhosa bulbs increased over nine-fold, from the equivalent of US$60 in 2002 to US$560 per kg in 2017. To date, cultivation has been unable to meet the entire market demand for F. cirrhosa bulbs, although other Fritillaria species are successfully cultivated on a larger scale.

Abstract
The normal commissure is not a simple joint of the upper and lower lip, but a triangular mucosal area. To reconstruct a symmetrical oral commissure in patients with a unilateral transverse facial cleft, we designed composite vermilion flaps, including triangular flaps. We retrospectively studied 17 patients with unilateral transverse facial clefts from 2013-2016. Three-dimensional images were obtained with a 3-dimensional photogrammetry system at the 1-year follow-up, and we used an anthropometric method to evaluate the postoperative symmetry of the commissure. No obvious deformity was found during the follow-up examination, and comparison of the cleft and non-cleft sides by the paired samples t test showed that in all cases both horizontally and vertically symmetrical commissures had been achieved.

Abstract
BACKGROUND Altered visceral sensation is common in irritable bowel syndrome (IBS) and nerve growth factor (NGF) participates in visceral pain development. Sodium butyrate (NaB) could induce colonic hypersensitivity via peripheral up-regulation of NGF in animals. Enteric glial cells (EGCs) appear to be an important source of NGF. Whether butyrate could induce visceral hypersensitivity via increased EGC-derived NGF is still unknown. METHODS CRL-2690 cells were used for transcriptome analyses after butyrate treatment. Rats received butyrate enemas to induce colonic hypersensitivity. Colorectal distention test was performed to assess visceral sensitivity. Immunofluorescence studies were used to evaluate the co-expression of glial fibrillary acidic protein (GFAP) and NGF or growth associated protein 43 in animal model. NGF expression in rat colon was also investigated. In vitro, CRL-2690 cells were stimulated with NaB or trichostatin A (TSA). NGF or GFAP expression was also examined. KEY RESULTS Transcriptome analyses showed that butyrate induced marked changes of genes expression related to neurotrophic signaling pathways. NaB-treated rats showed increased visceral sensitivity. An improved NGF expression level was observed in NaB-treated rats. Meanwhile, a 2.1-fold increase in co-expression of GFAP and NGF was also determined in rats received NaB enemas. In cultured cells, both NaB and TSA treatment could cause obvious NGF expression. Thus, butyrate might regulate EGC function via histone deacetylase inhibition. CONCLUSIONS & INFERENCES Butyrate-EGC interplay may play a pivotal role in regulation of NGF expression and the development of colonic hypersensitivity in IBS-like animal model.
