Abstract
OBJECTIVES Studies related to air pollutants and spontaneous abortion in urban northwestern China are scarce, and the main exposure windows of pollutants acting on pregnant women are unclear. STUDY DESIGN Case-control study. METHODS Data were collected from pregnant women in Tongchuan City from 2018 to 2019. A total of 289 cases of spontaneous abortion and 1156 cases of full-term labor were included and analyzed using a case-control study. Logistic regression models were developed to explore the relationship between air pollutants and spontaneous abortion after Chi square analysis and Air pollutant description. RESULTS O3 (odds ratio [OR] = 1.028) is a risk factor for spontaneous abortion throughout pregnancy. PM2.5 (OR = 1.015), PM10 (OR = 1.010), SO2 (OR = 1.026), and NO2 (OR = 1.028) are risk factors for spontaneous abortion in the 30 days before the last menstrual period. PM2.5 (OR = 1.015), PM10 (OR = 1.013), SO2 (OR = 1.036), and NO2 (OR = 1.033) are risk factors for spontaneous abortion in the 30-60 days before the last menstrual period. PM2.5 (OR = 1.028), PM10 (OR = 1.013), SO2 (OR = 1.035), and NO2 (OR = 1.059) are risk factors for spontaneous abortion in the 60-90 days before the last menstrual period. CONCLUSION Exposure to high levels of air pollutants may be a cause of increased risk of spontaneous abortion, especially in the first trimester of the last menstrual period.

Abstract
PURPOSE/OBJECTIVE(S) The application of weak magnetic fields may improve radiation therapy efficacy by manipulating the free radical activity induced by radiation to optimize tumor death. Once the device is commercially available, we will conduct clinical trials to determine the clinical impact of the weak magnetic field. However, the magnetic field generator (MFG) restricts Linac gantry rotation to approximately 180° and this limitation may limit treatment plan quality. This work is a continuation of an ongoing study to determine if the gantry angle restrictions can be compensated for during treatment planning. MATERIALS/METHODS Previous work has demonstrated the feasibility for GBM cases. For this work, 10 prostate cancer treatment plans were retrospectively replanned using only coplanar arcs that spanned from 90° to 270° (half-arcs). The prescriptions were 60 Gy for 6 patients, 55.8 Gy for 2 patients, 54 Gy for 1 patient, and 40.05 Gy for 1 patient. The prescription doses were delivered to 95% of the planning target volume (PTV = GTV + 2 cm). The critical structure doses were compared to determine if clinically equivalent plans could be delivered using half-arcs. RESULTS The dose criteria that were met by the clinical plans were also met by the half-arc plans except for the cases shown in Table 1. Table 1: Doses that did not meet criteria CONCLUSION: The half-arc plans were able to deliver clinically equivalent dose distributions as the clinical treatment plans. This provides continuing evidence that clinical trials will be able to be developed to evaluate the use of weak magnetic fields for radiation therapy.

Abstract
PURPOSE/OBJECTIVE(S) Radiographic MRI response following prostate radiotherapy, particularly stereotactic body radiotherapy (SBRT), remains poorly understood. Our objective was to describe radiographic changes to the prostate gland and prostate tumor following SBRT of men treated on a prospective, randomized trial. MATERIALS/METHODS MIRAGE (NCT04384770) is a single center, randomized phase III trial of patients receiving either CT or MRI guided SBRT for localized prostate cancer. Patients underwent pre-treatment and annual post-treatment MRIs, in addition to routine PSA surveillance. Outcomes reported include percent gland shrinkage, percent PSA response at one year, and presence of residual tumor based on radiographic interpretation. Patient characteristics were compared via two-sample t-test or Fischer's exact test. Both univariate and multivariable logistical analysis were employed to identify potential clinical predictors of residual tumor on 1-year follow up MRI. RESULTS This study cohort included 94 eligible patients with baseline characteristics in Table 1. Residual lesions were seen in 13 patients (14%), 5/27 (18.5%) treated without ADT and 8/67 (12%) with ADT. PSA ablation was deep, with a 79% median decrease without ADT and 98% median decrease with ADT. Patients receiving ADT showed more gland shrinkage (17% vs. 34% shrinkage, p = 0.0001), while radiographic non-responders and responders experienced similar gland shrinkage (median 21% vs 29% shrinkage, p > 0.05). No significant clinical predictors of residual tumor were identified on univariate and multivariate analysis. No patient had any clinical or biochemical evidence of failure. CONCLUSION A total of 14% of patients were found to have residual tumor detected on MRI one year after SBRT. These data highlight the protracted nature of radiographic tumor response to radiation therapy, even with ablative radiation techniques. The analysis is limited by the lack of biopsy data to quantify whether visualized residual tumor harbor active cancer.

Abstract
PURPOSE/OBJECTIVE(S) Compared to CT-guided radiotherapy, MRI-guided radiotherapy (MRgRT) has been shown to reduce acute physician-scored and patient-reported gastrointestinal and genitourinary (GU) toxicities associated with prostate stereotactic body radiotherapy (SBRT) in the MIRAGE randomized trial (NCT04384770). We hypothesize that real-time intrafraction tracking/gating is important and is a critical enabler of aggressive margin reduction with MRgRT. MATERIALS/METHODS 79 patients received MRgRT on the MIRAGE trial with a planning margin of 2mm around the prostate and proximal seminal vesicles, which were treated to 40 Gy in five fractions on an MR-Linac. Tracking was performed at 4 frames/second in the sagittal plane during treatment with a gating boundary of 3mm for automatic beam hold. An in-house tool was developed to extract treatment time and beam gating status based on treatment logs and real-time cine images. The ratio of the time that the target was within the gating window/total time of target inside or outside the gating boundary was defined as the duty cycle (DC). Target contours were extracted from each frame of tracking and overlaid to create a motion-convolved target occupancy map. Minimum isotropic expansions of the prostate to cover 85%, 90% and 95% of the intrafraction motion were calculated with and without gating. RESULTS Median treatment time per fraction including image guidance procedure and beam delivery was 24.3 min (IQR: 22.2-27.7 min). The median time for image guidance 5.4 min (IQR: 4.2-6.7 min). A total of 391 treatment fractions were analyzed and the median DC per fraction was 0.974 (IQR: 0.926 -0.983). 89 (22.8%) and 35 (9.0%) of fractions had DC<90% and <80%, respectively, corresponding to 50/79 (62.3%) and 24/79 (30.4%) of patients having at least one fraction with a DC<90% and <80%, respectively. The minimum duty cycle of all fractions was lower among patients with grade ≥2 GU toxicity compared to those with grade 0-1 GU toxicity (mean 79.8% vs. 85.9%, p = 0.06). The proportion of patients with grade ≥2 GU toxicity was also greater in patients with a minimum gating cycle <80% (37.5% vs. 18.2%, p = 0.06). Gating significantly decreased the minimum isotropic expansion of the prostate to cover 85%, 90% and 95% of the intrafraction motion (p<0.0001 for all). Prostate intrafraction motion tended to be along the bladder-rectum axis secondary to bladder filling, rectal gas and bulk motion. Fractions with large prostate motion were mostly stochastic. CONCLUSION A large fraction (30%) of patients had at least of one treatment fraction with DC<80%, which correlated with increased acute GU toxicity. Gating effectively reduces the expansion needed to cover prostate intrafraction motion, and is necessary for real-time motion management given the unpredictable nature of prostate motion.

Abstract
PURPOSE/OBJECTIVE(S) The post-operative prostate bed is a dynamic target volume due to the deformable nature of the bladder and rectum. These changes can lead to incorrect dosing of the prostate bed and organs at risk (OARs). Our objective was to quantify the dosimetric impact of prostate bed and OAR deformation. MATERIALS/METHODS SCIMITAR (NCT03541850) is a prospective phase II clinical trial evaluating stereotactic body radiotherapy (SBRT) in the post-prostatectomy setting. This analysis included a subset of patients who received 5 fractions of 6-6.8 Gy to the prostate bed under CT-based image guidance. The clinical target volume (CTV) and OARs were contoured on fractional CBCT images. Changes in volume, shape (via the dice similarity coefficient [DSC]), and dosimetry were quantified. Student's t-test was used to analyze the differences between planning and daily treatment outcomes. RESULTS A total of 29 patients (145 fractional images) were analyzed. We found the CTV volume remained stable (median change 1.1%; IQR: -15.1% - 16.1%), whereas the CTV shape was deformable (DSC of 0.76 [IQR: 0.71 - 0.79]). The bladder and rectum exhibited changes with median volume change of 5.7% (IQR: -24.3% - 51.0%) and 5.5% (IQR: -8.7% - 21.9%), respectively and median DSC of 0.77 (IQR: 0.68 - 0.84) and 0.74 (IQR: 0.69 - 0.80) respectively. The CTV received less radiation dose than planned (volume receiving 95%: 93.2% actual vs 99.6% planned, p < 0.01). 39% (56/145) of total fractions and 52% (15/29) of patients met criteria for CTV under-coverage (volume receiving 95% of the prescription dose < 93%). The rectum received higher dose than planned on several parameters (e.g., V27.5 Gy increased from 15.4% to 21.0% [p = 0.009] and V32.5 Gy increased from 6.0% to 10.9% [p = 0.006]) (Table 1). CONCLUSION We found underdosing of the prostate CTV and overdosing of the rectum in patients receiving CT-guided postoperative SBRT. While future work will correlate these dosimetric consequences with toxicity, these data suggest that approaches such as adaptive radiotherapy may be beneficial.

Abstract
PURPOSE/OBJECTIVE(S) The bladder trigone dosimetry is hypothesized to have a stronger correlation with post-SBRT urinary toxicity than that of the entire bladder. However, the trigone tends to move significantly between simulation and daily treatment. Its small size, large daily motion, and proximity to the target lead to potentially consequential but unaccounted-for dosimetric uncertainties. Manual segmentation of the structure can be inconsistent and time-consuming, even with MR-guided RT. Here, we propose and demonstrate a deep-learning-based framework for joint segmentation and landmark localization to support deformable registration and comprehensive dosimetric analysis. MATERIALS/METHODS A total of 30 patients were randomly selected for training, and 20 were held out for testing. Each patient had 1 simulation and 5 daily pre-treatment images obtained from a clinical 0.35T MR Linac. The trigone is defined as the triangular bladder section among three landmarks (2 ureteral orifices and the internal urethral orifice). In the manual contouring process, the 3 landmarks were identified first, followed by trigone segmentation. The proposed joint method uses a modified 3D nnU-Net with 2 decoders, one for segmentation and the other for landmark localization. The shared encoder is expected to extract features useful for both tasks. The joint framework was compared with a baseline method using two separate 3D nnU-Nets for landmark localization and trigone segmentation, respectively. Since the trigone is small (∼2% of the bladder volume), we further experimented with a second-stage prediction mimicking the human contouring process. The predicted landmarks from the first stage were used to crop the trigone region, and a second network was trained on cropped images. Evaluation metrics included the Dice score, 95% Hausdorff distance (HD95), and average surface distance (ASD) for segmentation, and Euclidean distance (ED) between the predicted and ground truth landmarks for localization. RESULTS The quantification metrics are summarized in the table below. The joint approach shows similar Dice performance to the baseline method but markedly better HD95 by 13%. For landmark localization, the proposed method is similar to the baseline, but the integration of the segmentation task stabilizes the training process. The two-stage approach further improves HD95, ASD, and ED by 27%, 24%, and 19%. CONCLUSION Combining segmentation and landmark localization exhibits a synergistic effect. The proposed two-stage approach provided additional improvement. Future studies will explore the deformable registration of the trigone based on the segmentation and landmark detection, as well as analyze cumulated dose distribution.

Abstract
PURPOSE/OBJECTIVE(S) Abscopal effect induced by radiotherapy and immune checkpoint blockade is a promising yet far from satisfactory strategy in clinical. The underlying immune mechanism, especially driven by monocytes remains poorly undefined. Monocytes consist of two phenotypically and functionally distinct subsets distinguished by expression of chemokine receptors CCR2 and CX3CR1: classical inflammatory Ly6ChiCCR2hi monocytes and nonclassical patrolling Ly6CloCCR2loCX3CR1hi monocytes. Monocytes differentiate and transit to other myeloid cells such as dendritic cells and macrophages according to various environmental cues. Herein we investigated the roles of monocyte subsets in modulating tumor control consisting of combination RT and myeloid checkpoint agonist αCD40 to specifically ignite myeloid cell activation. MATERIALS/METHODS To establish abscopal model, contralateral tumors were implanted in each mouse, while only one side were treated with RT (8 Gy × 3) + αCD40 agonist (50 μg, intra-tumor). Tumor volume and mice survival were compared in each group (control, RT, αCD40 and RT + αCD40). Ccr2RFP/+ Cx3cr1GFP/+ (R2 × 3), Ccr2RFP/RFPCx3cr1+/+ (R2-KO) and Ccr2+/+Cx3cr1GFP/GFP (X3-KO) mice were used for cell tracking and to dissect chemokine receptor CCR2 and CX3CR1 on monocyte. Tumor infiltrating immune cells were analyzed by flowcytometry and RNA-seq. RESULTS RT combined with αCD40 significantly dampened tumor growth on both ipsilateral and contralateral sides in abscopal model (p< 0.01), accompanied by upregulation of chemokine receptors CCR2 and CX3CR1 on myeloid cells were both increased in tumor and peripheral blood. Chemokine ligands CCL2, CCL3, CCL5, CCL7, CCL12 and CX3CL1 were upregulated in tumor after RT and αCD40 treatment, recruiting CCR2 and CX3CR1 expressing monocytes in situ. To elucidate the roles of CCR2 and CX3CR1 in mediating local and systemic anti-tumor immunity, R2 × 3, R2-KO and X3-KO mice with combined treatment were used. Tumor size on ipsilateral leg were similar among groups. However, tumor growth was significantly delayed on contralateral side in X3-KO mice while accelerated in R2-KO mice compared with that in R2 × 3 mice. Mechanistically, remarkable decrease of antigen presenting dendritic cells (MHCII+Ly6ChiCD11c+) were observed in R2-KO mice. Moreover, phagocytosis was strengthened in macrophages (F4/80+CD11b+) of X3-KO mice. CONCLUSION CX3CR1 deletion ignite anti-tumor immunity elicited by RT and αCD40 through enhanced phagocytosis in macrophages, while CCR2 deletion renders inferior tumor control through reduction of dendritic cells. Preferential targeting nonclassical patrolling monocyte may lead to enhanced local and systemic tumor control.

Abstract
Objective: To analyze the clinical characteristics and prognostic factors of patients with anti-melanoma differentiation-associated gene 5 (anti-MDA5)-positive dermatomyositis associated interstitial lung disease (DM-ILD). Methods: The patients with MDA5+DM-ILD who were admitted to Department of Respiratory Medicine, Nanjing Drum Tower Hospital from January 2017 to March 2021 were enrolled. The clinical data and survival information were analyzed retrospectively. Patients were divided into survival group or death group, and rapid progressive ILD (RP-ILD) group or non-rapid progressive ILD group, according to their survival status and clinical progression. Results: A total of 105 patients with anti-MDA5+DM-ILD (median age of onset 54 years) were enrolled, 58% being female (61 cases). The main sub-type of dermatomyositis was amyopathic dermatomyositis (n=74, 70%), followed by dermatomyositis (n=31, 30%). The main extrapulmonary manifestations were skin lesions (n=60, 57.1%), muscle manifestations(n=20, 19%) and arthralgia/arthritis (n=20, 19%). 15.4% of the patients had positive ANA (antibody titer≥1∶320), and 61.9% of the patients had anti-RO-52 kDa antibody. A total of 66 patients (62.8%) developed RP-ILD, and 58 patients (56.3%) died. Lower oxygenation index (OR=0.974, 95%CI:0.954-0.994, P=0.012) and no joint pain (OR=0.032, 95%CI: 0.002-0.663 P=0.026) were independent risk factors for RP-ILD. Cox regression analysis showed that RP-ILD (HR=3.194, 95%CI:1.025-9.954, P=0.045), older than 53 years (HR=3.450, 95%CI: 1.388-8.577, P=0.008), ferritin level more than 1 330.5 ng/ml (HR=3.032, 95%CI 1.208-7.610, P=0.018) and C-reactive protein (CRP) above 16.95 mg/L (HR=2.794, 95%CI:1.102-7.084, P=0.030) were independent predictors of mortality. Conclusions: The clinical manifestations of patients with anti-MDA5+DM-ILD presenting to the respiratory department were heterogeneous, with most being amyopathic dermatomyositis, and both the incidence of RP-ILD and the risk of death were high. Even in the absence of associated rash, joint, or muscle manifestations, anti-MDA5 antibody screening should be considered in patients with rapidly progressive ILD who were negative on baseline autoantibody screening but positive for anti-RO52kDa antibody.

Abstract
Objective: To explore the effect of blood lipids on the lesion distribution pattern in patients with acute ischemic stroke by using MRI technology based on population standard spatial analysis. Methods: The MRI data of 1 202 patients with acute ischemic stroke in General Hospital of Eastern Theater Command from January 2015 to December 2020 and Nanjing First Hospital from January 2013 to December 2021 were retrospectively collected, including 871 males and 331 females, aged 26 to 94 (64±11) years. According to the condition of blood lipids, they were divided into the dyslipidemia group (n=683) and the normal blood lipids group (n=519). After the automatic segmentation of diffusion-weighted imaging (DWI) images by artificial intelligence, the infarct sites were registered to the standard space which was used to draw the frequency heat map. The chi-square test was used to compare the difference in lesion location between the two groups. Generalized linear model regression analysis was used to observe the correlation between each blood lipid index and lesion site, and inter-group comparison and correlation analysis were used to observe the relationship between each blood lipid index and lesion volume. Results: Compared with the normal blood lipid group, the lesions in the dyslipidemia group were more extensive, mostly distributed in the occipital temporal region of the right posterior cerebral artery and the frontal region of the left middle cerebral artery. The brain regions of higher triglyceride(TG) and higher low-density lipoprotein cholesterol(LDL-C) groups were concentrated in the posterior circulation. The brain regions in the higher total cholesterol(TC) and lower high-density lipoprotein cholesterol(HDL-C) groups were concentrated in the anterior circulation(all P<0.05). In the anterior circulation infarct volume, the higher TC group was significantly higher than the normal TC group[(27.58±5.34) vs (17.73±1.18)ml, P=0.029]. In the posterior circulation infarct volume, the higher LDL-C group and the TG group were significantly higher than the normal LDL-C and TG groups[(7.55±2.51) vs (3.55±0.31) ml; (5.76±1.19) vs (3.36±0.30) ml](both P<0.05). Correlation analysis showed that TC and LDL-C were non-linearly (U-shaped) correlated with anterior circulation infarct volume (both P<0.05). Conclusions: Different blood lipids have effects on the distribution pattern and volume of ischemic stroke infarcts. Different hyperlipidemia is related to the specific distribution site and the larger extent of infarction.

Abstract
BACKGROUND Eribulin mesylate is a novel, nontaxane, microtubule dynamics inhibitor. In this study, we assessed the efficacy and safety of eribulin versus eribulin plus the oral small-molecule tyrosine kinase inhibitor anlotinib in patients with locally recurrent or metastatic breast cancer. PATIENTS AND METHODS In this single-center, open-label, phase II clinical study (NCT05206656) conducted in a Chinese hospital, patients with human epidermal growth factor receptor 2 (HER2)-negative, locally recurrent or metastatic breast cancer previously treated with anthracycline- or taxane-based chemotherapy were randomized (1 : 1) to receive eribulin alone or in combination with anlotinib. The primary efficacy endpoint was investigator-assessed progression-free survival (PFS). RESULTS From June 2020 to April 2022, a total of 80 patients were randomly assigned to either eribulin monotherapy or eribulin plus anlotinib combination therapy, with 40 patients in each group. The data cut-off was 10 August 2022. The median PFS was 3.5 months [95% confidence interval (CI) 2.8-5.5 months] for eribulin and 5.1 months (95% CI 4.5-6.9 months) for eribulin plus anlotinib (hazard ratio = 0.56, 95% CI 0.32-0.98; P = 0.04). The objective response rates were 32.5% versus 52.5% (P = 0.07), respectively, and disease control rates were 67.5% versus 92.5% (P = 0.01), respectively. Patients <50 years of age, with an Eastern Cooperative Oncology Group performance status score of 0, visceral metastasis, number of treatment lines of four or more, hormone receptor negative (triple-negative), and HER2 low expression appeared to benefit more from combined treatment. The most common adverse events in both groups were leukopenia (n = 28, 70.0%, patients in the eribulin monotherapy group versus n = 35, 87.5%, patients in the combination therapy group), aspartate aminotransferase elevations (n = 28, 70.0%, versus n = 35, 87.5%), neutropenia (n = 25, 62.5%, versus n = 31, 77.5%), and alanine aminotransferase elevations (n = 25, 62.5%, versus n = 30, 75.0%). CONCLUSION Eribulin plus anlotinib can be considered an alternative treatment option for HER2-negative locally advanced or metastatic breast cancer.

Abstract
Introduction Immature ovarian teratomas are a type of malignant germ cell tumor composed of complicated cell types and are characterized by pathological features of immature neuroectodermal tubules/rosettes. However, there is a lack of understanding of patient-derived immature ovarian teratomas (PDT) at the single cell level. Moreover, whether stem cell lines derived from immature teratomas (CDT) can be used as models for research on PDT remains to be elucidated. Methods Single-cell RNA sequencing (scRNA-seq) and subsequent bioinformatic analysis was performed on three patient-derived immature ovarian teratomas (PDT) samples to reveal the heterogeneity, evolution trajectory, and cell communication within the tumor microenvironment of PDT. Validations were conducted in additional seven samples through multiplex immunofluorescence. Result A total of qualified 22,153 cells were obtained and divided into 28 clusters, which can match to the scRNA-seq annotation of CDT as well as human fetal Cell Atlas, but with higher heterogeneity and more prolific cell-cell crosstalk. Radial glia cells (tagged by SOX2) and immature neuron (tagged by DCX) exhibited mutually exclusive expression and differentiated along distinct evolutionary trajectory from cycling neural progenitors. Proportions of these neuroectodermal cell subtypes may play important roles in PDT through contributing to the internal heterogeneity of PDTs. Moreover, the immune cells in PDTs were infiltrated rather than teratoma-derived, with more abundant macrophage in immature neuron than those in radial glia cells, and the infiltrated macrophage subtypes (i.e., M1 and M2) were significantly correlated to clinical grade. Overall, suppressed evolution process and transcriptome regulation in neuroectodermal cells, reduced cell-cell crosstalk, higher M1/M2 proportion ratio, and enhanced T cell effects in tumor microenvironment are enriched in patients with favorable prognosis. Discussion This study provides a comprehensive profile of PDT at the single cell level, shedding light on the heterogeneity and evolution of neuroectodermal cells within PDTs and the role of immune cells within the tumor microenvironment. Also, our findings highlight the potential usage of CDTs as a model for research on PDT.

Abstract
Cancer-associated fibroblasts (CAFs) are the predominant components of the tumor microenvironment (TME) and influence cancer hallmarks, but without systematic investigation on their ubiquitous characteristics across different cancer types. Here, we perform pan-cancer analysis on 226 samples across 10 solid cancer types to profile the TME at single-cell resolution, illustrating the commonalities/plasticity of heterogenous CAFs. Activation trajectory of the major CAF types is divided into three states, exhibiting distinct interactions with other cell components, and relating to prognosis of immunotherapy. Moreover, minor CAF components represent the alternative origin from other TME components (e.g., endothelia and macrophages). Particularly, the ubiquitous presentation of endothelial-to-mesenchymal transition CAF, which may interact with proximal SPP1+ tumor-associated macrophages, is implicated in endothelial-to-mesenchymal transition and survival stratifications. Our study comprehensively profiles the shared characteristics and dynamics of CAFs, and highlight their heterogeneity and plasticity across different cancer types.

Abstract
BACKGROUND Osteoarthritis (OA) affects the entire joint, initially with a low degree of inflammation. Synovitis is correlated with the severity of OA clinical symptoms and cartilage degradation. The synovial lymphatic system (SLS) plays a prominent role in clearing macromolecules within the joint, including the pro-inflammatory cytokines in arthritic status. Scattered evidence shows that impaired SLS drainage function leads to the accumulation of inflammatory factors in the joint and aggravates the progression of OA, and the role of SLS function in OA is less studied. DESIGN This review summarizes the current understanding of synovial lymphatic function in OA progression and potential regulatory pathways and aims to provide a framework of knowledge for the development of OA treatments targeting lymphatic structure and functions. RESULTS SLS locates in the subintima layer of the synovium and consists of lymphatic capillaries and lymphatic collecting vessels. Vascular endothelial growth factor C (VEGF-C) is the most critical regulating factor of lymphatic endothelial cells (LECs) and SLS. Nitric oxide production-induced impairment of lymphatic muscle cells (LMCs) and contractile function may attribute to drainage dysfunction. Preclinical evidence suggests that promoting lymphatic drainage may help restore intra-articular homeostasis to attenuate the progression of OA. CONCLUSION SLS is actively involved in the homeostatic maintenance of the joint. Understanding the drainage function of the SLS at different stages of OA development is essential for further design of therapies targeting the function of these vessels.

Abstract
Background: The aesthetic facial traits are closely related to life quality and strongly influenced by genetic factors, but the genetic predispositions in the Chinese population remain poorly understood. Methods: A genome-wide association studies (GWAS) and subsequent validations were performed in 26,806 Chinese on five facial traits: widow’s peak, unibrow, double eyelid, earlobe attachment, and freckles. Functional annotation was performed based on the expression quantitative trait loci (eQTL) variants, genome-wide polygenic scores (GPSs) were developed to represent the combined polygenic effects, and single nucleotide polymorphism (SNP) heritability was presented to evaluate the contributions of the variants. Results: In total, 21 genetic associations were identified, of which ten were novel: GMDS-AS1 (rs4959669, p = 1.29 × 10−49) and SPRED2 (rs13423753, p = 2.99 × 10−14) for widow’s peak, a previously unreported trait; FARSB (rs36015125, p = 1.96 × 10−21) for unibrow; KIF26B (rs7549180, p = 2.41 × 10−15), CASC2 (rs79852633, p = 4.78 × 10−11), RPGRIP1L (rs6499632, p = 9.15 × 10−11), and PAX1 (rs147581439, p = 3.07 × 10−8) for double eyelid; ZFHX3 (rs74030209, p = 9.77 × 10−14) and LINC01107 (rs10211400, p = 6.25 × 10−10) for earlobe attachment; and SPATA33 (rs35415928, p = 1.08 × 10−8) for freckles. Functionally, seven identified SNPs tag the missense variants and six may function as eQTLs. The combined polygenic effect of the associations was represented by GPSs and contributions of the variants were evaluated using SNP heritability. Conclusion: These identifications may facilitate a better understanding of the genetic basis of features in the Chinese population and hopefully inspire further genetic research on facial development.

Abstract
Objective: To raise the awareness of idiopathic pleuroparenehymal fibroelastosis (iPPFE) through investigating the clinical, radiographic and pathological features. Methods: Five cases of iPPFE proved by pathology. The clinical data were studied respectively, and the relevant literature was reviewed. Results: All the cases of iPPFE were manifested by cough and dyspnea. The patients including 3 males and 2 females, aged from 30 to 70 years Chest CT scan showed pleural thickening, subpleural consolidation in both upper lungs complicated with tractive bronchiectasis.Computed tomography-guided percutaneous lung biopsy or surgical lung were performed and the same pathological showed pleura and subpleural dense elastic and collagen fibers. The elastic fibers stain was also positive,which was consistent with PPFE. One patient received low-dose corticosteroid, two received pirfenidone therapy, the others received no treatment. Three patients were stable during the follow-up. Conclusions: iPPFE has characteristic pathological features. However, the number of clinically reported cases is low due to missed diagnosis or misdiagnosed. Improving the understanding of features of iPPFE is helpful for the dianosis, therapy, and prognosis of this disease.

Abstract
OBJECTIVES The frail elderly have an increased risk of frailty because of reduced physical activity, cognitive ability and quality of life. This study aims to evaluate the effects of integrated exercise intervention on the attenuation of frailty in elderly nursing home residents. DESIGN This study was a cluster randomized controlled trial. SETTING AND PARTICIPANTS 146 elderly frailty people from 8 elderly nursing homes in Harbin, China, were randomly assigned into the intervention group and control group after obtaining their informed consent. INTERVENTION The intervention group performed integrated exercise interventions for 12 months, while the control group only continued with their daily activities. MEASUREMENTS Sociodemographic, health-related data, frailty levels, gait parameters, cognition, and quality of life were evaluated. RESULTS The mean age of participants was 80.74± 2.89 years, and 70.37% (n=95) were female. The Difference-in-difference regression showed that, compared with the control group, phenotypic frailty score (β3 =-1.40, p < 0.001) and stride time (β3 = -0.38, p <0.001) decreased significantly in the intervention group, stride velocity (β3 = 0.24, p < 0.001), step length (β3 = 0.08, p <0.001), cadence (β3 = 17.79, p < 0.001), MMSE total score (β3 = 1.90, p < 0.001) and QOL total score (β3 = 11.84, p < 0.001) increased significantly in the intervention group. CONCLUSION The integrated exercise intervention can effectively improve the attenuation of frailty, gait parameters, cognitive function, and quality of life in elderly nursing homes. We can use the findings of this study as a reference for the design of activities for the elderly nursing home residents, to provide them with appropriate exercises, improve their physical functions, and improve or delay their frailty level, which is principally important for developing countries in east Asia where rehabilitation resources are generally scarce.

Abstract
OBJECTIVE The systemic spread of colorectal cancer (CRC) is dominated by the portal system and exhibits diverse patterns of metastasis without systematical genomic investigation. Here, we evaluated the genomic evolution of CRC with multiorgan metastases using multiregion sequencing. DESIGN Whole-exome sequencing was performed on multiple regions (n=74) of matched primary tumour, adjacent non-cancerous mucosa, liver metastasis and lung metastasis from six patients with CRC. Phylogenetic reconstruction and evolutionary analyses were used to investigate the metastatic seeding pattern and clonal origin. Recurrent driver gene mutations were analysed across patients and validated in two independent cohorts. Metastatic assays were performed to examine the effect of the novel driver gene on the malignant behaviour of CRC cells. RESULTS Based on the migration patterns and clonal origins, three models were revealed (sequential, branch-off and diaspora), which not only supported the anatomic assumption that CRC cells spread to lung after clonally expanding in the liver, but also illustrated the direct seeding of extrahepatic metastases from primary tumours independently. Unlike other cancer types, polyphyletic seeding occurs in CRC, which may result in late metastases with intermetastatic driver gene heterogeneity. In cases with rapid dissemination, we found recurrent trunk loss-of-function mutations in ZFP36L2, which is enriched in metastatic CRC and associated with poor overall survival. CRISPR/Cas9-mediated knockout of ZFP36L2 enhances the metastatic potential of CRC cells. CONCLUSION Our results provide genomic evidence for metastatic evolution and indicate that biopsy/sequencing of metastases may be considered for patients with CRC with multiorgan or late postoperative metastasis.

Abstract
Silicosis is an occupational lung parenchymal disease caused by inhaling silica. It requires differentiation from a malignant tumour and granulomatous disease. We describe the case of a woman with silicosis who exhibited enlargement of bilateral cervical lymph nodes, pericardial effusion and lung abnormalities. She was diagnosed with silicosis based on histological examination of a resected cervical lymph node, lung tissue biopsy and history of silica exposure. She underwent glucocorticoid therapy during hospitalization. The lung abnormalities, enlarged cervical lymph nodes and pericardial effusion were ameliorated by glucocorticoid therapy, but she relapsed shortly thereafter. In conclusion, silicosis with cervical lymph node enlargement and pericardial effusion is rare and should be differentiated from a malignant tumour and granulomatous disease. Some patients may respond well to steroids in the short term.

Abstract
The long-term feeding of a high-concentrate diet (the concentrate ratio is greater than 60 %) leads to mammary gland inflammatory response in ruminants and decreased quality in dairy cows and affects the robust development of the dairy industry. The main reason is closely related to elevated lipopolysaccharide (LPS) in the body. In this experiment, a bovine mammary epithelial cell line (MAC-T) was used as a model, and LPS at different concentrations (0 ng/ml, 1 ng/ml, 10 ng/ml, 100 ng/ml, 1000 ng/ml, 10000 ng/ml) was added to the cells. The cell survival rate, oxidative stress indicators, total lipid droplet area, triglyceride content and key genes regulating lipid metabolism were detected by 3-(4,5)-dimethylthiahiazo(-z-y1)-3,5-di-phenytetrazoliumromide (MTT), assay kit, microscope observation and RT-PCR methods to explore the regulatory mechanism of mammary health and milk fat synthesis. The results showed that compared with those of the control group, the survival rates of cells were significantly decreased after 9 h of stimulation with 1000 ng/ml and 10000 ng/ml LPS (P<0.01). The contents of superoxide dismutase (SOD), catalase (CAT) and total antioxidant capacity (T-AOC) in cells were significantly decreased (P<0.05). Compared with that of the control group, the content of malondialdehyde (MDA) in cells was significantly increased (P<0.05) after stimulation with 10000 ng/ml LPS for 9 h. After 9 h of stimulation with 100 ng/ml, 1000 ng/ml and 10000 ng/ml LPS, the total lipid drop area and triglyceride (TG) content of MAC-T cells were significantly decreased (P<0.05). The expression levels of fatty acid synthesis-related genes Acetyl-CoA carboxylase (ACC) and Stearoyl-CoA desaturase 1 (SCD-1) were significantly decreased after 9 h of stimulation with 100 ng/ml, 1000 ng/ml and 10000 ng/ml LPS (P<0.05), while the expression levels of Fatty Acid synthetase (FAS) were significantly decreased after stimulation with 1000 ng/ml and 10000 ng/ml LPS (P<0.05). TG synthesis by the related gene Diacylglycerol acyltransferase-1 (DGAT1) was significantly lower than that of the control group after stimulation with 1000 ng/ml and 10000 ng/ml LPS for 9 h (P<0.05), and Diacylglycerol acyltransferase-2 (DGAT2) also showed a significant decrease after 10000 ng/ml LPS stimulation (P<0.05). In conclusion, adding different concentrations of LPS to MAC-T cells not only led to a decrease in cell activity, resulting in oxidative damage, but also affected fatty acid and TG synthesis, which may ultimately be closely related to the decrease in milk fat synthesis.

Abstract
BACKGROUND Surgery is the most effective way to treat bromhidrosis, but postoperative complications are still the biggest obstacles for patients to choose surgical treatment. OBJECTIVES To introduce an innovative application of follicular unit extraction (FUE) in the treatment of bromhidrosis. METHODS We conducted a case series study on 20 patients who received FUE technique for the treatment of bromhidrosis. The axillary hair follicles were extracted with a one-millimetre punch. The released hair follicles were collected for histological examination. After the operation, the wounds were wrapped with moderate pressure. The dressing was removed 24 h after the FUE operation. The postoperative complications were collected, and the improvement of malodour was evaluated by the 10-point visual analogue scale. RESULTS Immediately postoperation, many needle-shaped holes appeared in the armpits. The holes healed 7 days after the operation, with no scar or pinpoint-like scars. Except for a female who complained of mild pain in the left armpit, no other patients had any discomfort. The malodour level varied between 0 and 4 during the follow-up period. The tissue examination showed that more than 90% of the completely plucked hair follicles were accompanied by apocrine glands, and many blocked and dilated apocrine glands were observed. The lumens of the blocked glands were filled with decapitation products, which were positive for K5, Brst-2 and CEA. CONCLUSIONS Patients with bromhidrosis have a positive response to FUE technique. The FUE technique is well-tolerated, with only a few postoperative complications, which deserves to be widely promoted.

Abstract
Objective: To understand the time for observation and related factors in the clinics after vaccination among children's parents. Methods: From December 2019 to January 2020, parents of children aged 0-3 years were recruited by multiple-stage sampling from 34 vaccination clinics in 12 districts and counties in 6 provinces (Shandong, Guangdong, Henan, Sichuan, Inner Mongolia, and Liaoning). A questionnaire survey on the time of observation after vaccination was conducted. A multivariate logistic regression model was used to analyze the related factors of parental observation time after vaccination. Results: A total of 3 292 parents of 0-3 year's old children were selected, and 3 178 parents were finally included in the analysis. 87.85%(2 792/3 178) of the parents reported that the observation time after vaccination at clinics was ≥30 minutes. Multivariate logistic regression analysis showed that, after adjusting for the regions, the main factors affecting the observation time at clinics after vaccination among parents appeared as observation time informed by physicians at the clinic appeared ≥30 minutes (OR=31.622, 95%CI: 19.847-50.384), parents were medical personnel (OR=2.779, 95%CI: 1.505-5.133), parents being volunteers working on vaccination-related publicity and education activities (OR=1.986, 95%CI: 1.438-2.743), parents aged 35 years old or above (OR=1.900, 95%CI: 1.215-2.971), being parents of the first child (OR=1.663, 95%CI: 1.282-2.156), per capita annual income of the family as 8 000- Yuan (OR=1.646, 95%CI: 1.168-2.319), children aged 0-12 months old (OR=1.646, 95%CI: 1.203-2.252) or 13-24 months old (OR=1.506, 95%CI: 1.064-2.133), obedient to physicians' advice at the clinic (OR=1.481, 95%CI: 1.067-2.055). Conclusions: The proportions of parents observed for ≥30 minutes at the clinics of vaccination were high. When the information was from the physicians at the vaccination clinic, the observation time was the most critical factor for parents to observe at clinics as required.

Abstract
Objective: To understand the overall satisfaction rate with vaccination services in parents of children, and the impact of additional time consumed for vaccination service on overall satisfaction rate. Methods: From December 2019 to January 2020, a total of 3 178 parents of 0-3 years old children were investigated to collect the information about their basic characteristics, additional time spent for vaccination service and overall satisfaction through questionnaires. Binary logistic regression model and restricted cubic spline model were used to evaluate the impact of additional time spend on the overall satisfaction rate. Results: The overall satisfaction rate of parents with vaccination services was 92.32%. The median time for parents to move from home to vaccination clinic was 10.00 (10.00, 20.00) minutes, the median waiting time to make an appointment was 10.00 (5.00, 15.00) minutes, the median waiting time for vaccination was 5.00 (3.00, 10.00) minutes, and the median total additional time spent was 30.00 (20.00, 45.00) minutes. The binary logistic regression analysis showed that after adjusting the relevant factors, the main factors affecting the overall satisfaction rate were the waiting time for making an appointment (the 4- minutes group vs. 8- minutes group: OR=1.863, 95%CI: 1.307-2.657), waiting time for vaccination (the <4 minutes group vs. 8- minutes group: OR=1.529, 95%CI: 1.102-2.120; the 4- minutes group vs. 8- minutes group: OR=1.534, 95%CI: 1.104-2.130), total additional time spent (the 15- minutes group vs. 30- minutes group: OR=1.470, 95%CI: 1.094-1.976). Restricted cubic spline analysis showed that the waiting time for making an appointment (non-linear: χ2=13.18, P=0.001), the waiting time for vaccination (non-linear: χ2=13.50, P=0.001), and the total additional time consumed (non-linear: χ2=9.38, P=0.009) showed a non-linear inverted "V" dose response relationship to the overall satisfaction of vaccination services. Conclusions: The waiting time for parents to make an appointment, the waiting time for vaccination and the total additional time spent for receiving vaccination services affected the overall satisfaction rate of the vaccination services. And the waiting time for making an appointment was the most important factor, and it is necessary to shorten the waiting time for appointment. It is suggested that the vaccination clinic should make use of information technology (such as WeChat public account, APP) to make accurate appointments, make appointments to the time period to control the number of people within time period.

Abstract
Long-term forest dynamics monitoring plots provide information on number of individual species in the plot, allowing us for the first time to construct seed dormancy profiles at the species and individual levels for a specific site. Focusing on the Xishuangbanna tropical season rainforest plot (XTRDP), we used data from nine forest dynamics plots (two for tropical, four for subtropical and three for temperate) and information on kind of seed dormancy to generate seed dormancy profiles for communities across tropical to temperate latitudes at the species and individual levels. Seed dormancy information was collected from previous publications, and some data were provided by two germplasm banks that test seed germination of wild plants in China. In XTRDP, 35% of the species and 58% of individuals have non-dormant seeds; the dominant species have non-dormant seeds. In all plots, the most common kind of dormancy among species and individuals with dormant seeds was physiological dormancy. At the species level, the profile for tropical, subtropical and temperate plots was similar to profiles for each of these vegetation regions. In all plots, except one subtropical plot, the percentage of species versus individuals with dormant seeds differed. All temperate plots had a higher percentage of individuals than species with dormant seeds, but this pattern was not consistent for tropical or subtropical plots. We show that dormancy increases with latitude at both the species and individual levels. Dormancy profiles at the individual tree level provide new insight into seed dormancy relationships within plant communities.

Abstract
Inherited predispositions to acute lymphoblastic leukemia have been well investigated in pediatric patients, but studies on adults, particularly Chinese patients, are limited. In this study, we conducted a genome-wide association study in 466 all-age Chinese patients with Acute lymphoblastic leukemia (ALL) and 1,466 non-ALL controls to estimate the impact of age on ALL susceptibility in the Chinese population. Among the 17 reported loci, 8 have been validated in pediatric and 1 in adult patients. The strongest association signal was identified at ARID5B locus and gradually decreased with age, while the signal at GATA3 exhibited the opposite trend and significantly impact on adult patients. With genome-wide approaches, germline variants at 2q14.3 rank as the top inherited predisposition to adult patients (e.g., rs73956024, P = 4.3 × 10-5) and separate the genetic risk of pediatric vs. adult patients (P = 3.6 × 10-6), whereas variants at 15q25.3 (e.g., rs11638062) have a similar impact on patients in different age groups (overall P = 2.9 × 10-7). Our analysis highlights the impact of age on genetic susceptibility to ALL in Chinese patients.

Abstract
BACKGROUND Anaplastic thyroid cancer (ATC) is a rare but lethal malignancy, and few systematic investigations on genomic profiles of ATC have been performed in Chinese patients. METHODS Fifty-four ATC patients in West China Hospital between 2010 to 2020 were retrospectively analyzed, while 29 patients with available samples were sequenced by whole-exome sequencing (WES). The associations between genomic alterations and clinical characteristics were statistically evaluated. RESULTS The median overall survival was 3.0 months in the entire cohort, which was impacted by multiple clinical features, including age, tumor size, and different treatment strategies. In the WES cohort, totally 797 nonsilent mutations were detected; the most frequently altered genes were TP53 (48%), BRAF (24%), PIK3CA (24%), and TERT promoter (21%). Although these mutations have been well-reported in previous studies, ethnic specificity was exhibited in terms of mutation frequency. Moreover, several novel significantly mutated genes were identified including RBM15 (17%), NOTCH2NL (14%), CTNNA3 (10%), and KATNAL2 (10%). WES-based copy number alteration analysis also revealed a high frequent gain of NOTCH2NL (41%), which induced its increased expression. Gene mutations and copy number alterations were enriched in phosphatidylinositol 3-kinase/AKT/mechanistic target of rapamycin (mTOR), NOTCH, and WNT pathways. CONCLUSIONS This study reveals shared and ethnicity-specific genomic profiles of ATC in Chinese patients and suggests NOTCH2NL may act as a novel candidate driver gene for ATC tumorigenesis.

Abstract
We describe a 40-year-old female who presented with progressive breathlessness and hypercapnic respiratory failure during pregnancy secondary to undiagnosed muscle-specific kinase myasthenia gravis. Her presentation was progressive and protracted, having over five contacts with healthcare professionals over nine months, many of these predating her pregnancy. Her atypical presentation for myasthenia with minimal limb weakness led to consideration of other causes of hypercapnic respiratory failure. Once diagnosed, she was treated with intravenous immunoglobulin and non-invasive ventilation. She gave birth to a pre-term infant by planned caesarean section. Her insidious presentation and the progressive nature of her breathlessness were unusual and our report highlights the predominant involvement of respiratory muscles in muscle-specific kinase myasthenia. Her pregnancy may have further delayed her diagnosis due the attribution of some symptoms to normal pregnancy. Early recognition and treatment of myasthenia gravis are important to prevent life-threatening complications.

Abstract
BACKGROUND A few epidemiological investigations and animal studies have demonstrated that bisphenol A (BPA) may affect female reproductive health. However, no epidemiologic study has investigated the relationship between BPA exposure and the risk of premature ovarian insufficiency (POI). METHODS In this case-control study, urinary concentrations of BPA and serum levels of reproductive hormone were measured. Associations between BPA concentrations and the risk of POI and POI-related hormone levels were estimated. RESULTS Among BPA quartiles, no obvious association was found between BPA levels and the risk of POI (p = 0.603). Although the adjusted odds ratio (OR) of POI was slightly increased for participants in the highest BPA concentration quartile, the association was not statistically significant (OR = 1.282, 95% confidence interval [CI] 0.615-2.049 for the highest vs. lowest quartile, p = 0.508). Although follicle stimulating hormone (FSH) and anti-Mullerian hormone (AMH) levels showed no tendency of an association with BPA (p = 0.941 and p = 0.876 for FSH and AMH, respectively), the highest quartile of luteinizing hormone was significantly positively associated with BPA levels (OR = 1.333, 95% CI 0.986-1.803, p = 0.042). CONCLUSIONS The urinary concentrations of BPA determined in this study were consistent with the range of exposure currently observed in Chinese women. However, BPA exposure at a relatively low level is not associated with POI in Chinese women. Further epidemiological studies are needed to confirm our findings.

Abstract
Monoterpenes present in the essential oils exhibit anti-inflammatory properties. In this study, we investigated the preventive effect of alpha-pinene (AP), a monoterpene, against isoproterenol (ISO)-induced myocardial infarction and inflammation in Wistar rats. Male Wistar rats were pretreated with AP (50 mg/kg body weight (bw)) administration for 21 days and ISO (85 mg/kg bw) was administered subcutaneously for last two consecutive days (20th day and 21st day). We noticed that there was an increased activity of cardiac marker enzymes in ISO-treated rats. We also observed that elevated levels of lipid peroxidative indices decreased activities of antioxidant status in plasma, erythrocyte, and heart tissue in ISO-induced rats. Furthermore, ISO-treated rats showed an increase in the levels of inflammatory mediators like tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in the serum. Besides, we confirmed the upregulated expression of TNF-α, IL-6, and nuclear factor kappa-light-chain-enhancer of activated B cells in ISO-induced rat heart tissue. Conversely, we found that AP pretreatment significantly decreased levels of cardiac markers like serum cardiac troponin T and cardiac troponin I, lipid peroxidative markers, and restored antioxidants status in ISO-treated rats. Besides, AP administration attenuated ISO-induced inflammatory marker expression. The present findings demonstrated that AP significantly protects the myocardium and exerts cardioprotective and anti-inflammatory effects in experimental rats.

Abstract
A small proportion of patients with acute lymphoblastic leukemia (ALL) may experience severe leukopenia after treating with 6-mercaptopurine (6MP), which can be largely explained by germline variants in TPMT and NUDT15. However, a minority of patients who suffered such adverse drug reaction have NUDT15 wt/wt TPMT wt/wt genotype, indicating that other genetic factors may take part in. In this study, we genotyped 539 exon-located nonsilent pharmacogenetic variants in genes involved in phase I/II of drug metabolism in 173 pediatric patients with ALL and conducted association screening for 6MP-induced leukopenia. Besides NUDT15 (rs116855232, P = 6.4 × 10-11) and TPMT (rs1142345, P = 0.003), a novel variant was identified in CYP2A7 gene (i.e., rs73032311, P = 0.0007), which is independent of NUDT15/TPMT variant. In addition, a variant (i.e., rs4680) in COMT is significantly associated with 6MP-induced hepatotoxicity (P = 0.007). In conclusion, variants in CYP2A7 and COMT may be considered as novel potential pharmacogenetic markers for 6MP-induced toxicities, but additional independent validations with large sample size and investigations on related mechanisms are further needed.

Abstract
AIM To undertake a systematic review and meta-analysis of the diagnostic performance of CT for differentiating peritoneal tuberculosis (PTB) from peritoneal carcinomatosis (PC). MATERIAL AND METHODS PubMed, Embase, the Web of Science, and the Cochrane Library were searched for papers published before 23 July 2019. The methodological quality of the studies was analysed. Overlapping descriptors used in different studies to denote the same image finding were subsumed under a single CT feature. Sensitivity, specificity, and positive and negative likelihood ratios were pooled. A summary receiver operating characteristic curve (sROC) was constructed and the area under the curve (AUC) of the included studies was calculated when possible. RESULTS Six studies were included and 17 CT features were analysed. The pooled sensitivity and specificity of smooth peritoneal thickening were 59% (95% CI: 52-66%) and 84% (95% CI: 79-88%), respectively. The AUC of smooth peritoneal thickening was 0.83. Omentum line/rim, lymph node necrosis or calcification, and mesenteric macro nodules had a pooled specificity ranging from 95% to 100% and a pooled sensitivity ranging from 12% to 67%. The other 12 signs had a pooled sensitivity ranging from 21% to 79% and a pooled specificity ranging from 19% to 81%. Omentum involvement (cake-like pattern) showed a threshold-effect, so only the AUC (=0.70) was calculated. CONCLUSIONS Smooth peritoneal thickening shows fairly good diagnostic accuracy, while omentum rim/line, lymph nodes necrosis or calcification, mesenteric macro nodules have good specificity but limited sensitivity. The informative features summarised in this study may aid clinical practice and future studies.

Abstract
Doctors and patients attempt to accelerate orthodontic tooth movement with a minimally invasive surgery approach. The purpose of this systematic review was to evaluate the evidence of accelerated tooth movement in minimally invasive surgery and the adverse effects from it. A systematic search of the literature was performed in the electronic databases of PubMed, CENTRAL (Cochrane Central Register of Controlled Trials), Embase, Scopus, Web of Science, Science Direct, and Medline and was complemented by a manual search until February 2019. The inclusion criteria were prospective clinical studies of patients treated with a fixed appliance, and the intervention was accelerated orthodontic treatment with minimally invasive surgery. Nineteen articles (538 participants) were included in the review: 9 studies assessed the rate of upper canine movement; 5 considered the treatment time; 1 evaluated the en masse retraction time; and 4 studied adverse effects. We performed a meta-analysis for the rate of canine movement and treatment time and described the results for the adverse effects in a systematic review. The results of the subgroup analysis according to micro-osteoperforation and piezocision were included in the study. No accelerated tooth movement was found in the micro-osteoperforation group. After flapless corticotomy procedures, increased tooth movement rates were identified by weighted mean differences of 0.63 (95%CI = 0.22, 1.03, P = 0.003) and 0.64 (95% CI, −25 to 1.53; P = 0.16) for 1 and 2 mo, respectively. The mean treatment time was 68.42 d (95% CI, −113.19 to −23.65; P = 0.003) less that than for minimally invasive surgery. Moreover, no significant adverse effect was found. Because of the high heterogeneity of the meta-analysis, the results must be validated by additional large-sample multicenter clinical trials. There is not sufficient evidence to support that the single use of micro-osteoperforation could accelerate tooth movement, and there is only low-quality evidence to prove that flapless corticotomy could accelerate tooth movement.

Abstract
Abstract
Background
Acute ST-segment elevation myocardial infarction (STEMI) is typically characterized by an occlusive coronary thrombus propagation on a disrupted or eroded atherosclerotic plaque. A variable period of plaque instability and thrombus formation occur days or weeks old in approximately 50% of patients with STEMI. Presence of late stage (older) thrombi in aspirated coronary material is an independent predictor of 1-year and long-term mortality in STEMI patients. However, the relationship between coronary thrombus healing to underlying plaque morphology and characteristics in vivo still remains largely unknown.
Purpose
Our objective was to assess differences in thrombus healing between ruptured and eroded plaques in vivo and evaluate the impact of underlying plaque characteristics on thrombus healing using optical coherence tomography (OCT).
Methods
Analyzable coronary material was obtained during primary percutaneous coronary intervention (PCI) from 135 patients with STEMI within 12h of symptom onset. Thrombi were morphologically classified as either early or late stage (lytic changes or organization). Of the 135 patients, 110 were eligible for culprit lesion evaluation using OCT. Quantitative and qualitative underlying plaque characteristics were assessed by OCT.
Results
Late-stage thrombi were found in 49 of 110 (44.5%) culprit plaques. Patients with eroded plaques more frequently had late-stage thrombi compared with ruptured plaques (59.0% vs. 36.6%, p<0.001). Subgroup analysis was performed between plaque rupture, identified in 71 patients (64.5%) and plaque erosion in 39 patients (35.5%). In plaque ruptures, patients with late-stage thrombi had larger lipid core length (12.4±3.3 vs. 14.5±3.8, p=0.020), larger rupture cavity length [1.5 (1.0, 2.0) vs. 1.9 (1.5, 2.8), p=0.034] and increased residual thrombus length [7.8 (6.3, 11.2) vs. 10.3 (7.8, 13.8), p=0.021] assessed by OCT compared with early thrombus group. However, in plaque erosions, late stage thrombi were associated with decreased residual thrombus burden compared with patients with early thrombus group [16.8 (12.8, 20.4) vs. 13.4 (10.7, 14.8), p=0.012]. No significant difference was found between thrombus healing with peak creatine kinase concentration or maximum NT-pro BNP in subgroup analysis.
Conclusions
Coronary thrombi in STEMI patients exhibited diverse phases of healing, depending on the etiology of the underlying culprit plaque in vivo. These observations indicate entirely distinct mechanisms of thrombus propagation, maturation and healing between plaque rupture and erosion, illustrating an opportunity for more tailored treatment in patients with different plaque type.
