Abstract
Data evaluating changes in bone mineral density (BMD) in Down syndrome (DS) individuals remains controversial. Therefore, we conducted a systematic review and meta-analysis to better understand associations between BMD and DS. A systematic literature search of PubMed, EMBASE, Web of Science, and the Cochrane Library up until 1st January 2021 was conducted. We used the keywords "bone mineral density" and "Down Syndrome." Fifteen studies were included. Overall, our results showed a significant decrease in BMD of total body (TB BMD) [MD = - 0.18; 95% CI (- 0.23 and - 0.12), P < 0.00001, I2 = 89%], total hip (TH BMD) [MD = - 0.12; 95% CI (- 0.15 and - 0.10), P < 0.00001, I2 = 0%], lumbar spine (LS BMD) [MD = - 0.12; 95% CI (- 0.14 and - 0.09), P < 0.00001, I2 = 18%], and femoral neck (FN BMD) [MD = - 0.08; 95% CI (- 0.10 and - 0.06), P < 0.00001, I2 = 0%] in DS individuals when compared with controls. Moreover, the volumetric BMD of lumbar spine (LS vBMD) [MD = - 0.01; 95% CI (- 0.02 and - 0.01), P = 0.0004, I2 = 19%] also showed a decreasing tendency while the volumetric BMD of the femoral neck (FN vBMD) [MD = 0.01; 95% CI (0.00 and 0.02), P = 0.02, I2 = 0%] was elevated in DS individuals versus controls. These findings demonstrated that individuals with DS had a decreased total and regional (TH, LS, and FN) BMD when compared with the general population. Additionally, when BMD was adjusted for skeletal volume, LS vBMD was also lower, while FN vBMD was elevated in DS individuals versus controls.

Abstract
Background Up to now, epidemiological studies on allergy rhinitis (AR) have primarily focused on determining the risk of disease in Chinese adults, with the majority of them designed by single centers, while cross-sectional and epidemiological data describing allergic sensitization in children with self-reported AR are scarce. Objective This study was estimating of the latest information about the sensitization patterns and risk factors of clinical AR to develop effective strategies for the prevention and treatment of AR. Methods We conducted a cross-sectional survey between January 2020 and June 2021 involving children from seven cities in China who reported AR. A total of 762 children participated in this survey. To evaluate the risk factors and specific sensitization patterns of clinical AR through questionnaires and specific immunoglobulin E to 11 aeroallergens. Results Of the 762 patients, 593 (77.8%) had at least one positive IgE level. Aged 7–14 years (OR 1.503, (95% CI 1.058–2.136), P = 0.023); With allergic conjunctivitis (OR 1.843, (95% CI 1.297–2.620), P = 0.001) and living in the Eastern (OR 1.802, (95% CI 1.263–2.573), P = 0.001) all elevated the risk of clinical AR associated with aeroallergens. The sensitization rates of D. pteronyssinus and D. farinae were higher than those of other allergens in the 0–6 and 7–14 years old age groups. The most common aeroallergens among self-reported children with AR in the eastern were D. farinae (74.9%) and D. pteronyssinus (74.3%), while in the western were mugwort (60.0%) and marguerite (56.6%). Majority of sIgE-positive subjects were sensitized to three or more of the tested pollen allergens in the Western (52.1%), compared with 5.7% in the Eastern. Conclusion There was an apparent geographic variation in childhood allergies in China. Age factors also had strong impacts on the allergen sensitization rate of children, but these impacts differed across regions.

Abstract
Hydrochar has been demonstrated to increase methane production rate during anaerobic digestion (AD) of organic wastes/wastewater by facilitating direct interspecies electron transfer (DIET). The present study compared the hydrochars prepared at different conditions (260 °C-1 h, 260 °C-8 h, 320 °C-1 h and 320 °C-8 h) on AD of glucose. Hydrochar prepared at lower temperature and residence time (260 °C-1 h) resulted in the highest methane production rate, which was 237% higher of control experiment without hydrochar. Modification of hydrochar (260 °C-1 h) by ball-milling further increased the capacity to increase methane production rate. Hydrothermal liquefaction (HTL) conditions affected the surface oxygen-containing functional groups that related with DIET, and hydrochar (260 °C-1 h) had higher peaks relating with C-O and O-H functional groups. Ball-milling enhanced the formation of such groups. Microbial analysis showed hydrochar (260 °C-1 h) by ball-milling resulted in the formation of different microbial communities as compared with control experiments, and Azospira and Methanosarcina were enriched, which might be involved in DIET.

Abstract
Background Horizontal neck wrinkle formation is gaining more attention among cosmetic practitioners and clients. To date, hyaluronic acid products are one of the most common treatment options for this aesthetic concern. However, different therapeutic strategies should be given to solve the problem due to multiple etiological reasons. Given that oxidative damage plays a critical role in neck wrinkle formation, anti-oxidative compounds are now considered by physicians when making a treatment plan. Aims To evaluate the efficacy and safety of a non-cross-linked hyaluronic acid filler in combination with L-carnosine in treating horizontal neck wrinkles. Methods Thirteen patients with a Wrinkle Assessment Scale (WAS) of 2–5 for horizontal neck wrinkles were treated with L-carnosine-containing non-cross-linked hyaluronic acid. Participants were followed-up for 3 months after treatment. The post-treated WAS scores evaluated by physicians were collected when patient satisfaction was surveyed. Any post-treatment adverse events were recorded. Results With a single injection of the above filler, the physician-evaluated WAS scores improved by at least one score at one month and the improvement kept consistent as far as three months after injection. According to the last follow-up visit, 11/13 patients were satisfied with the treatment effect of their neck wrinkle. Moreover, adverse events were rare after filler injection, except for local complications that were considered common reactions to the filler injection procedure. Conclusion The non-cross-linked hyaluronic acid filler containing L-carnosine is safe and effective for treating horizontal neck wrinkles.

Abstract
BACKGROUND The combination of navigational system and robotics has the potential to accurately identify and drill bone tunnels in anterior cruciate ligament (ACL) reconstruction. This study explores the feasibility and accuracy of bone tunnel positioning using the TiRobot, an orthopaedic surgical robot. METHODS The experiment was divided into two groups. In group A, the bone tunnels were positioned using the TiRobot surgical robot (n = 8). In group B, handheld locators were used for positioning (n = 8). RESULTS TiRobot can be used for positioning the ACL bone tunnel. The accuracy of positioning the femoral tunnel in group A and B was 1.00 ± 0.20 and 3.10 ± 0.59 mm, respectively (t = -9.49, P < 0.001). As for tibial tunnel, the accuracy was 1.02 ± 0.20 and 2.64 ± 0.14 mm, respectively (t = -18.54, P < 0.001). CONCLUSIONS The bone tunnel drilling precision using TiRobot for ACL reconstruction surgery was more accurate than traditional surgical techniques.

Abstract
BACKGROUND An accurate interpretation of the ABO blood group of an individual is of utmost importance to ensure patient safety and good transfusion practices. The aim of the study was to determine the incidence and causes of ABO typing discrepancies among patients and analysis of the clinical characteristics as well. METHODS A retrospective observational study was carried out in the Department of Laboratory Medicine in the General Hospital of Chinese PLA from March 2018 to December 2020. Records of patients were collected and analyzed for frequency, clinical characteristics, and influencing factors of ABO typing discrepancies. RESULTS There were 132 ABO typing discrepancies patients (57 females, 75 males), aged from 3 to 84 (50.3 ± 19.3) years, with history of operation 89 cases (67.42%) and blood transfusion 23 cases (17.42%). In the control group, there were 142 cases (63 females and 79 males), aged 10 - 78 years (50.5 ± 15.55), with operation history 68 cases (47.88%) and blood transfusion history 2 cases (1.40%). Among the inconsistent blood types group, there were 59 cases (44.7%) type B, 38 cases (28.8%) type A, 28 cases (21.2%) type AB, and 7 cases (5.3%) type O. There were 21 cases (15.9%) in the department of hematology, 15 cases (11.36%) in the department of orthopedics, 14 cases (10.6%) in the department of hepatobiliary surgery, 11 cases (8.33%) in the department of general surgery, 11 cases (8.33%) in the department of vascular surgery, and less than 5% in other departments. The common cause of ABO typing discrepancies was due to low/weak affinity antibody (3.79%), low/weak affinity antibody B (18.18%), weak A antigen (3.03%), weak B antigen (12.12%), hematopoietic stem cell transplantation (10.60%), irregular antibody (46.70%), subtype (3.79%), and cold agglutination (1.51%). The diseases in the ABO discrepancy group mainly included hematological disorders, malignant tumors, osteoarthritis and so on. Binary logistic regression showed that hematological disorders, malignant tumors, history of operation (p = 0.01), and history of blood transfusion (p = 0.017) were the influencing factors of ABO typing discrepancies. CONCLUSIONS It is possible that the antibody of ABO blood group system could not be detected. The independent influence factors were hematological disorders, malignant tumor, blood transfusion history and operation history for ABO typing discrepancies. It was necessary to analyze the causes correctly and judge the correct blood group by serological methods.

Abstract
Drug resistance is a major hurdle for the effectiveness of tamoxifen (TAM) to provide clinical benefit. Therefore, it is essential to identify a sensitizer that could be used to improve TAM efficacy in treating TAM-resistant breast cancer. Here, we investigated the ability of baicalein to reverse TAM resistance. We found that baicalein increased the efficacy of TAM in inhibiting proliferation and inducing apoptosis of TAM-resistant cells. It also enhanced the TAM-induced growth reduction of resistant cells from NOD/SCID mouse mammary fat pads, without causing obvious systemic toxicity. Analyses using the CellMiner tool and the Kaplan-Meier plotter database showed that HIF-1α expression was inversely correlated with TAM therapeutic response in NCI-60 cancer cells and breast cancer patients. HIF-1α expression was increased in TAM-resistant cells due to an increase in mRNA levels and reduced ubiquitin-mediated degradation. Baicalein reduced HIF-1α expression by promoting its interaction with PHD2 and pVHL, thus facilitating ubiquitin ligase-mediated proteasomal degradation and thereby suppressing the nuclear translocation, binding to the hypoxia-response element, and transcriptional activity of HIF-1α. As a result, baicalein downregulated aerobic glycolysis by restricting glucose uptake, lactate production, ATP generation, lactate/pyruvate ratio and expression of HIF-1α-targeted glycolytic genes, thereby enhancing the antiproliferative efficacy of TAM. Furthermore, baicalein interfered with HIF-1α inhibition of mitochondrial biosynthesis, which increased mitochondrial DNA content and mitochondrial numbers, restored the generation of reactive oxygen species in mitochondria, and thus enhanced the TAM-induced mitochondrial apoptotic pathway. The HIF-1α stabilizer dimethyloxallyl glycine prevented the baicalein-induced downregulation of glycolysis and mitochondrial biosynthesis and reduced the effects of baicalein on reversing TAM resistance. Our results indicate that baicalein is a promising candidate to help overcome TAM resistance by sensitizing resistant cells to TAM-induced growth inhibition and apoptosis. The mechanism underlying the effects of baicalein consists of inhibition of HIF-1α-mediated aerobic glycolysis and mitochondrial dysfunction.

Abstract
Abstract
Introduction/Objective
NTRK3 gene encodes a transmembrane protein receptor of the tropomyosin receptor kinase (Trk) family. Gene fusions involving NTRK3 result in a constitutive activation or overexpression of Trk receptor, potentially leading to oncogenesis. NTRK targeted therapies show a promising activity in varied cancer types with NTRK fusions. The aim of this case review is to describe the clinical and pathologic findings of thyroid neoplasm with NTRK3 gene fusions.
Methods/Case Report
The cytology fine needle aspiration (FNA), molecular testing results and pathology of surgical resections are reviewed in 220 cases of total and hemithyroidectomy from January 2018 to May 2021.
Results (if a Case Study enter NA)
Three cases with NTRK3 gene fusions are identified by Thyroseq or Afirma GSC from FNA of thyroid nodules with later surgical intervention. No other mutations or gene fusions were identified. Each case had total thyroidectomy. Case 1 is a 41-year-old female with FNA diagnosis of suspicious for papillary thyroid carcinoma (PTC) and ETV6/NTRK3 fusion found by Afirma GSC. Pathology diagnosis is PTC classic type, two tumor nodules 1.1cm and 1.0cm, lymphovascular invasion not identified, three lymph nodes not involved by tumor and pathologic stage pT1b(m) pN0. Case 2 is a 49-year-old female with FNA diagnosis of atypia of undetermined significance and ETV6/NTRK3 fusion detected by Thyroseq. Pathology diagnosis is infiltrative PTC follicular variant, 2.0cm, angioinvasion present, no lymph nodes submitted and pathologic stage pT1b(m) pNX. Case 3 is a 28-year-old female with FNA diagnosis of suspicious for follicular derived neoplasm and NTRK3/RBPMS fusion is detected by Afirma GSC. Pathology diagnosis is infiltrative PTC follicular variant, 1.5cm, 9 of 11 lymph nodes positive for metastatic carcinoma and pathologic stage pT1b pN1b.
Conclusion
Thyroid neoplasm with NTRK3-rearrangement is rare. Cases 1 and 2 with common ETV6-NTRK3 fusion show PTC classic type and infiltrative PTC follicular variant with angioinvasion. Case 3 with less common NTRK3/RBPMS fusion shows infiltrative PTC follicular variant and significant lymph node involvement. Our limited cases of NTRK3-rearranged thyroid carcinoma demonstrate infiltrative growth, diverse phenotypes, one case with angioinvasion and no lymph nodes submitted and one case with multiple lymph node metastasis. This suggests aggressive behavior of thyroid cancer with NTRK3 gene fusion and patients may benefit from targeted NTRK therapy.

Abstract
Abstract
Introduction/Objective
Thyroid adenoma-associated (THADA)-IGF2BP3 fusions is related to strong overexpression of insulin-like growth factor 2 mRNA-binding protein 3 (IGF2BP3) mRNA and protein, increased IGF2 translation and IGF1 receptor signaling via PI3K and MAPK pathways. THADA-IGF2BP3 have been identified as an oncogenic event in thyroid neoplasms, but the clinicopathologic features have not been greatly evaluated. The purpose of this cases review is to describe the clinical and pathologic findings of thyroid nodules with THADA-IGF2BP3 fusion on molecular testing.
Methods/Case Report
Surgical Pathology 220 cases of total and hemithyroidectomy from January 2018 to December 2019 were reviewed for cytology fine needle aspiration (FNA), molecular testing results and surgical resection pathology.
Results (if a Case Study enter NA)
Three cases of THADA-IGF2BP3 fusion identified by Thyroseq testing from FNA of thyroid nodules with all diagnosed as atypia of undetermined significance, Bethesda category 3. No other mutations or gene fusions are identified. Successive surgical interventions are performed. Case 1 is a 49-year-old female right hemithyroidectomy with pathologic diagnosis of papillary thyroid carcinoma (PTC) follicular variant with tumor capsular invasion and no lymphvascular invasion. The tumor is 2cm, two lymph nodes evaluated are not involved by tumor and pathological stage is pT1b pN0. Case 2 is a 71-year-old female total thyroidectomy and the pathologic diagnosis is PTC follicular variant with tumor capsular invasion and no lymphvascular invasion. The tumor is 2cm, one lymph node evaluated is not involved by tumor and pathologic stage is pT1b pN0. Case 3 is a 76-year-old male left hemithyroidectomy and pathologic diagnosis is PTC follicular variant with tumor capsular invasion and no lymphvascular invasion. The tumor is 2cm, two lymph nodes evaluated are not involved by tumor and pathologic stage is pT1b pN0.
Conclusion
THADA-GF2BP3 fusion is uncommon in thyroid neoplasms and only three cases are detected in 220 cases evaluated. The three cases of thyroid nodules are all diagnosed as AUS by FNA, and all are diagnosed as PTC follicular variant with capsular invasion upon resection without lymphvascular invasion or lymph node involvement. THADA-F2BP3 fusion is associated with thyroid carcinoma, with low-risk non-aggressive behavior, conservative surgery appears necessary and lobectomy is likely adequate.

Abstract
Abstract
Introduction/Objective
Endometrial stromal sarcoma (ESS), a rare malignant neoplasm of endometrial stroma, accounts for less than 1% of all uterine tumors. High grade ESS (HGESS) is aggressive and commonly relapses even after surgical and neoadjuvant therapy. Abdominal and pelvic regions are common sites of metastasis, however, distant metastases to the liver, lung, vertebrae, and brain have been reported.
Methods/Case Report
We encountered a 49-year-old female who presented with shortness of breath, found to have a left pleural effusion and multiple pleural masses. She initially presented three years ago with heavy irregular menses and left pelvic pain for one year. D&C revealed prominent small spindle cells for which a stromal nodule and low-grade or malignant process was probable. CT scan showed an enlarged uterus. Hysterectomy with bilateral salpingo- oophorectomy, bilateral pelvic and para-aortic lymph node dissection, and partial omentectomy were performed. The uterus revealed an intramural 7 cm mass with a serpiginous growth pattern and lymphovascular invasion. Tumor cells were plump to spindled with areas of high cellularity, rounded nuclei, increased atypia and mitosis. Atypical areas were positive for cyclin D1, focally positive for CD10, and negative for ER, PR, SMA, desmin, AE1/3 and CAM5.2. FISH studies showed rearrangement of YWHAE gene (17p13.3) and no rearrangement of JAZF1 or PHF1 gene regions. Findings supported the diagnosis of HGESS. The patient received post-operative chemotherapy. Biopsy of the current pleural lesion revealed a nonspecific malignant spindle cell neoplasm positive for BCL1, CD56, CD117, CD99, TLE1 and INI1, while negative for AE1/3, CAM5.2, EMA, ER, PR, CK5/6, calretinin, SMA, desmin and S100. The CD10 stain was inconclusive. FISH studies showed rearrangement of YWHAE gene (17p13.3) and no rearrangement involving JAZF1 or PHF1 gene regions. No rearrangement of the SS18 gene region was observed and synovial sarcoma was excluded. Overall findings support the diagnosis of metastatic HGESS.
Results (if a Case Study enter NA)
NA
Conclusion
HGESS, a rare tumor with a nonspecific immunostain profile, has the ability to metastasize to rare body sites, such as the pleura in our case. Display of spindle cell morphology is a nonspecific finding that raises broad differential diagnoses. In women, with or without a history of uterine neoplasm, HGESS is a clinically worthwhile diagnosis to be mindful of.

Abstract
Dorzagliatin is a novel allosteric glucokinase activator targeting both pancreatic and hepatic glucokinase currently under clinical investigation for treatment of type 2 diabetes (T2D). This study aimed to investigate the effect of renal impairment (RI) on dorzagliatin’s pharmacokinetics (PKs) and safety, and to guide appropriate clinical dosing in patients with diabetic kidney disease, including end‐stage renal disease (ESRD). Based on the results from physiologically‐based pharmacokinetic modeling, the predicted outcome of RI on dorzagliatin PK property would be minimum that the plasma exposure area under concentration (AUC) of dorzagliatin in patients with ESRD would increase at about 30% with minimal change in peak concentration (Cmax) comparing to those in healthy volunteers (HVs). To definitively confirm the prediction, a two‐part RI study was designed and conducted based on regulatory guidance starting with the patients with ESRD matched with HVs. Results of the RI study showed minimum difference between patients with ESRD and HVs with respect to dorzagliatin exposure with geometric mean ratio of ESRD to HV at 0.81 for Cmax and 1.11 for AUC. The elimination half‐life, volume of distribution, and systemic clearance for dorzagliatin were similar between the two groups. Dorzagliatin was well‐tolerated in patients with ESRD during the study. Therefore, RI showed no significant impact on dorzagliatin PK, suggesting that dorzagliatin can be readily used in patients with T2D at all stages of RI without need for dose adjustment.

Abstract
Body size is an important trait in companion animals. Recently, a primitive Japanese dog breed, the Shiba Inu, has experienced artificial selection for smaller body size, resulting in the "Mame Shiba Inu" breed. To identify loci and genes that might explain the difference in the body size of these Shiba Inu dogs, we applied whole genome sequencing of pooled samples (pool-seq) on both Shiba Inu and Mame Shiba Inu. We identified a total of 13,618,261 unique SNPs in the genomes of these two breeds of dog. Using selective sweep approaches, including F ST, H p and XP-CLR with sliding windows, we identified a total of 12 genomic windows that show signatures of selection that overlap with nine genes (PRDM16, ZNF382, ZNF461, ERGIC2, ENSCAFG00000033351, CCDC61, ALDH3A2, ENSCAFG00000011141, and ENSCAFG00000018533). These results provide candidate genes and specific sites that might be associated with body size in dogs. Some of these genes are associated with body size in other mammals, but 8 of the 9 genes are novel candidate genes that need further study.

Abstract
During the domestication of the goose a change in its feather color took place, however, the molecular mechanisms responsible for this change are not completely understood. Here, we performed whole-genome resequencing on three pooled samples of geese (feral and domestic geese), with two distinct feather colors, to identify genes that might regulate feather color. We identified around 8 million SNPs within each of the three pools and validated allele frequencies for a subset of these SNPs using PCR and Sanger sequencing. Several genomic regions with signatures of differential selection were found when we compared the gray and white feather color populations using the FST and Hp approaches. When we combined previous functional studies with our genomic analyses we identified 26 genes (KITLG, MITF, TYRO3, KIT, AP3B1, SMARCA2, ROR2, CSNK1G3, CCDC112, VAMP7, SLC16A2, LOC106047519, RLIM, KIAA2022, ST8SIA4, LOC106044163, TRPM6, TICAM2, LOC106038556, LOC106038575, LOC106038574, LOC106038594, LOC106038573, LOC106038604, LOC106047489, and LOC106047492) that potentially regulate feather color in geese. These results substantially expand the catalog of potential feather color regulators in geese and provide a basis for further studies on domestication and avian feather coloration.

Abstract
Background: The varying effectiveness of anterior cruciate ligament (ACL) injury
prevention programs between soccer and basketball may be due to differences
in sport-specific injury mechanisms. Bone bruise patterns may provide
information regarding injury mechanisms. Purpose: To compare bone bruise and meniscal injury patterns for ACL injuries
sustained in soccer versus basketball. Study Design: Cross-sectional study; Level of evidence, 3. Methods: Clinical notes, operative reports, and magnetic resonance imaging scans were
reviewed for patients who sustained a noncontact ACL rupture while playing
soccer or basketball between August 2016 and August 2018. The presence,
location, and signal intensity of bone bruises on the tibia and femur were
documented, and patterns were classified according to the location of the
bone bruise in the lateral-medial direction. The meniscal and bone bruise
injury patterns and the specific bone bruise locations were compared between
the soccer and basketball groups. Results: Overall, 138 patients were included (56 with soccer-related and 82 with
basketball-related ACL injury). No significant difference between the groups
was observed in bone bruise patterns (P = .743) or meniscal
injury patterns (P = .952). Bone bruise on the lateral side
only of both the femur and the tibia was the most common pattern in both
soccer (41.9%) and basketball (47.0%) groups; the most common meniscal
injury type was an isolated lateral meniscal injury in both soccer (50.0%)
and basketball (45.0%) groups. For patients with bone bruises on both the
lateral and the medial sides of both the femur and the tibia (BF+BT), the
bone bruise signal intensity on the lateral side of the femur
(P < .001) and tibia (P = .009) was
significantly higher than that on the medial side for both groups. The bone
bruises on the lateral side of the femur (P < .001) and
tibia (P = .002) were significantly more anterior than
those on the medial side for patients with the BF+BT pattern. Conclusion: No significant differences in bone bruise location or meniscal injury type
were detected when comparing ACL injuries sustained during soccer versus
basketball. The study results suggest a similar biomechanical loading
pattern for ACL injuries in these sports.

Abstract
Vietnam’s transition towards a market orientation has generated many changes in cultural values, competing demands and diverse expectations related to managerial leadership. This study makes a timely contribution to both theory and practice by exploring what makes effective leadership in the Vietnam’s context. Taking into account ‘universalistic’ and ‘contextual’ perspectives, this study addresses two research questions regarding the characteristics of indigenous leadership in Vietnam and its interaction with coexisting cultural values and norms in the country’s transition. These research questions were examined based on 48 qualitative interviews conducted across a broad spectrum of domestic-private, foreign-invested and state-owned companies. Study findings enrich the understanding of indigenous interpretations of the leadership phenomenon and provide support for context-specific examinations of general management leadership issues in transitional economies.

Abstract
BACKGROUND The altered coordination variability was related to anterior cruciate ligament (ACL) re-injury after ACL reconstruction (ACL-R). As motor performance is affected by the cognitive loading, understanding the interaction of cognition and coordination variability is crucial for addressing secondary injury prevention and restoring function in rehabilitation programs. RESEARCH QUESTION To investigate the lower extremity movement coordination variability asymmetry in individuals following ACL-R and determine the effects of cognitive loading on the coordination variability. METHODS Twenty-five males who received unilateral ACL-R using hamstring tendon autograft (7.4 ± 1.3 months past reconstruction). Participants performed walking without (single-task condition) and with the concurrent cognitive task (dual-task condition). The coordination variability in hip-knee coupled motion in different gait phases was calculated using vector coding technique. RESULTS The injured leg demonstrated greater coordination variability in hip flexion/knee flexion (HF/KF) during mid-stance phase (P = 0.012) than the uninjured leg in both conditions. No significant differences were observed in other phases of HF/KF variability or other measures in all phases between the injured and uninjured legs. Both legs increased the HF/KF coordination variability during loading response phase in dual-task condition than that in single-task condition (P < 0.001). SIGNIFICANCE Individuals following ACL-R demonstrated coordination variability asymmetry of sagittal plane hip-knee coupled motion. The dual cognitive task increased the coordination variability of hip flexion/knee flexion during loading response phase in individuals following ACL-R.

Abstract
Alcohol drinking has been established as a major risk factor for esophageal diseases. Our previous study showed that ethanol exposure inhibited PAX9 expression in human esophageal squamous epithelial cells in vitro and in vivo. In this study, we aimed to investigate the molecular pathways through which alcohol drinking suppresses PAX9 in esophageal squamous epithelial cells. We first demonstrated the inhibition of NOTCH by ethanol exposure in vitro. NOTCH regulated PAX9 expression in KYSE510 and KYSE410 cells in vitro and in vivo. RBPJ and NOTCH intracellular domain (NIC) D1 ChIP-PCR confirmed Pax9 as a direct downstream target of NOTCH signaling in mouse esophagus. NOTCH inhibition by alcohol drinking was further validated in mouse esophagus and human tissue samples. In conclusion, ethanol exposure inhibited NOTCH signaling and thus suppressed PAX9 expression in esophageal squamous epithelial cells in vitro and in vivo. Our data support a novel mechanism of alcohol-induced esophageal injury through the inhibition of NOTCH-PAX9 signaling. © 2020 The Pathological Society of Great Britain and Ireland.

Abstract
Purpose
Although team reflexivity has been identified as a potent tool for improving organizational performance, how and when it influences individual employee innovative behavior remains theoretically and conceptually underspecified. Taking a knowledge management perspective, this study aims to investigate the role of team-level knowledge sharing and leadership in transforming team reflexivity into innovative behavior at the individual level.
Design/methodology/approach
The paper follows a multilevel study design to collect data (n = 441) from 91 teams in 48 knowledge-based organizations. The paper tests our multilevel model using multinomial logistic techniques.
Findings
The overall results confirm that knowledge sharing in teams mediates the influence of team reflexivity on individual employee innovative behavior, and that leadership plays an important role in moderating these influences. Specifically, authoritarian leadership is found to attenuate the team reflexivity and knowledge sharing effect, whereas benevolent leadership is found to amplify this indirect effect.
Originality/value
The multilevel study design that explains how team-level processes translate into innovative behavior at the individual employee level is novel. Relatedly, our use of a multilevel analytical framework is also original.

Abstract
PURPOSE The COVID-19 pandemic has suddenly brought about a number of disruptions to when and where work is undertaken for hospitality employees. The rapid spread of COVID-19 forced many hospitality managers to use digital technologies to perform work from home, termed digital work connectivity. Yet little is known about how hospitality employees cope with it. The purpose of this study is to investigate an important yet underspecified issue as to how digital work connectivity can be detrimental for employees' work behavior. DESIGN/METHODOLOGY/APPROACH We test our hypotheses using multi-wave and multi-source data collected from 467 middle managerial-level hospitality employees in China. FINDINGS The findings show that digital work connectivity can lead to self-control depletion, which in turn is associated with disengagement from work. Further, the findings show that relational energy is an important resource that can buffer the detrimental effects of digital work connectivity on hospitality employees. PRACTICAL IMPLICATIONS The association of digital work connectivity with employee withdrawal behavior highlights the urgent need for hospitality enterprises to have clear guidelines that regulate technology use at home for work purposes. SOCIAL IMPLICATIONS Our research shows that the absence of clear guidelines in relation to the use of digital technology for work at home risks producing unintended consequences for both hospitality employees and their enterprises. ORIGINALITY/VALUE Our research draws from recent advances in resource allocation theories of self-control and adopts a more nuanced approach to uncover a counterintuitive reality that while people use digital technology to remain connected with work, doing so can actually contribute to their withdrawal behavior.

Abstract
PURPOSE Previous evidence has shown that psychological stress can trigger the onset of autoimmune disease. This study aimed to investigate the prevalence of stressful life events preceding the onset of symptoms in female primary Sjogren's syndrome (pSS) in China compared to controls and the possible associations of stressful life events with disease activity. PATIENTS AND METHODS This was a hospital-based retrospective case-control study. Sixty-seven consecutive female pSS patients and an equal number of age-matched (± 3 years) healthy controls were recruited for assessment using the related Stressful Life Events Scale. The pSS disease activity was measured by the EULAR Sjogren's syndrome disease activity index. Data were analyzed by SPSS, version 23, using chi-square, univariate logistic regression, multiple logistic regression, and partial correlation. RESULTS A higher number of negative stressful life events before disease onset in pSS patients compared with healthy controls suggest that these play a role in increasing the risk of disease occurrence (OR = 2.59, 95% CI: 1.87-3.58, p < 0.05). The number of positive life events did not differ between the two groups. Both the number and severity of the negative stressful life events were also significantly correlated with disease activity. CONCLUSION Patients with pSS experienced more negative stressful life events in the year preceding the onset of symptoms than controls. Negative stressful life events before symptom onset may be risk factors for pSS and may affect pSS disease activity.

Abstract
OBJECTIVES To compare the ability of detailed routine ultrasound examination, performed without knowledge of maternal serology and fetal status, with that of targeted prenatal imaging performed in prenatal diagnostic units in cases of known fetal infection to identify cytomegalovirus (CMV)-infected fetuses that will develop long-term sequelae. METHODS All prenatal imaging reports were collected for 255 children with congenital CMV in a registered cohort between 2013 and 2017 (NCT01923636). All women had undergone detailed routine fetal ultrasound examination at 20-24 and 30-34 weeks as part of routine antenatal care. All cases of known fetal CMV infection had also undergone targeted prenatal ultrasound examination. Postnatal structured follow-up for up to 48 months of age involved clinical, audiological and neurological assessment, including Brunet-Lezine scoring. Long-term sequelae (> 12 months) were considered to be mild in cases with isolated unilateral hearing loss and/or vestibular disorders, and severe in cases with bilateral hearing loss and/or neurological sequelae. All imaging reports were analyzed retrospectively with the knowledge of congenital CMV infection, searching for reference to findings that were, or could have been, related to fetal infection. Findings were analyzed in relation to whether the cases were diagnosed with CMV in utero or only postnatally. RESULTS There were 237 children with complete follow-up data (> 12 months), for a median of 24 (range, 12-48) months. Of these, 30% (71/237) were diagnosed with CMV prenatally and 70% (166/237) were diagnosed within 3 weeks after birth. 72.5% (29/40) of children with long-term sequelae, including 74% (14/19) with severe long-term sequelae, were not identified in the prenatal period. Among those diagnosed prenatally, the sensitivity of prenatal imaging for predicting long-term sequelae and severe long-term sequelae was 91% and 100%, respectively, while, in the group diagnosed only postnatally, non-specific infection-related ultrasound findings had been reported without raising suspicion in 48% of cases with long-term sequelae and 64% of those with severe long-term sequelae. CONCLUSIONS Routine detailed ultrasound examination in pregnancy is not an appropriate screening tool for congenital CMV infection that leads to long-term sequelae, in contrast with the high performance of targeted prenatal imaging in known cases of fetal infection. The non-specific nature of ultrasound features of CMV and their evolution, and a lack of awareness of caregivers about congenital CMV, are likely explanations. Awareness of the sonologist regarding congenital CMV and knowledge of the maternal serological status in the first trimester seem key to the performance of prenatal ultrasound.

Abstract
Dorzagliatin, a novel glucokinase (GK) activator targeting both pancreatic and hepatic GK, is currently in late-stage clinical development for treatment of type 2 diabetes (T2D). For the optimization of dosing regimens to ensure adequate safety and efficacy, it is critical to have a deep understanding of pharmacokinetic (PK) and pharmacodynamic (PD) profiles of the drug in various targeting patient populations, considering the fact that T2D adversely affects a vast patient population who often times also suffer from a wide range of comorbidities including severe liver and/or kidney damage. Since drug efficacy seems to be closely related to unbound drug concentrations at the site of action, therefore, the determination of plasma unbound concentrations/fractions of dorzagliatin is of crucial importance, especially when performing the PK/PD assessment in those special populations. In the current study, a method was developed and validated for determining the unbound fraction (fu) of dorzagliatin in human plasma by using equilibrium dialysis for the separation of the bound and unbound drug, and LC-MS/MS for subsequent quantification. We have successfully addressed two widely recognized challenges for determination of the fu, i.e., the lack of knowledge on the "true fu" and the difficulty in assessing the accuracy and reproducibility of the measurement. Using this method, a 0.2 mL aliquot of human plasma samples were first dialyzed against 0.35 mL of phosphate buffered saline buffer at 37 °C for 5 h in the equilibrium dialysis device to separate the unbound dorzagliatin. Afterwards, post-dialysis samples were extracted by protein precipitation using acetonitrile. Separation of dorzagliatin and potential interferences were achieved using a Gemini C18 column coupled with gradient elution. Subsequent detection was carried out on tandem mass spectrometer operated by multiple reaction monitoring in positive mode using electrospray ionization. The standard curve over the concentration range of 0.125-250 ng/mL exhibits good linearity. The method was fully validated meeting the requirements in current bioanalytical guidance and was successfully applied in a clinical PK study of dorzagliatin in healthy volunteers and patients with renal function impairment. Method reproducibility was demonstrated in incurred sample reanalysis. With demonstrated accuracy, stability and reproducibility, reliable analytical results were obtained from clinical samples for PK/PD interpretation, providing valuable insight for the development of dorzagliatin.

Abstract
Measurements of cartilage defect size under an arthroscope are essential for prognosis and treatment decisions. A new method called arthroscopic measurement by computer graphics (ACG) was developed to accurately calculate the size of the cartilage under an arthroscope. This study aimed to validate the accuracy and utility of this method. In this controlled laboratory study, the ACG method was validated by measuring the sizes of three cartilage defects in a knee joint of a pig, using the following techniques: traditional arthroscopic measurement by ruler (TAR), ACG, incised measurement by computer graphics (ICG), and incised measurement by ruler (IR, control, gold standard). Measurements were conducted by two blinded trained observers. Intra- and inter-observer variabilities were determined by calculating the intra-class correlation coefficient (ICC). Consistency among TAR, ACG, ICG and IR was analyzed using the command "Concord" in Stata. For arthroscopic measurements using ACG and ICG, the overall ICC intra- and inter-observer values were 0.99 and 0.98, respectively, which showed excellent reproductivity. The concord value showed consistency of various approaches relative to the gold standard method. The average concord value for TAR was 0.813, and the average concord value for ACG and ICG was 0.886 and 0.917, respectively. ACG utilizes computer graphics for measuring the size of cartilage defects of any size under an arthroscope, without reconditioning the injured cartilage. ACG showed excellent intra- and inter-observer reproducibility and satisfactory accuracy. This method would make it possible to more accurately match the graft with the defect, thereby facilitating cartilage repair.

Abstract
Background Although studies have reported the sex differences in injury patterns among recreational skiers, the findings are still conflicting. This study aims to analyse the sex differences of orthopaedic knee injuries that occurred during alpine skiing. Methods A total of 306 recreational alpine skiers (125 females and 181 males) who sustained knee surgeries between June 2016 and December 2018 participated in this study. Age, height, weight, and physical activity level of the patients were recorded. The orthopaedic knee injury patterns were analysed based on the diagnosis given by the physicians. Results Male skiers (17.13%) had a higher proportion of multiple knee ligament injuries than females (6.40%). The combined anterior cruciate ligament (ACL) and medial collateral ligament injury were the most common injury types in both females and males, with ACL injury being more prevalent for females (79.20%) than that in males (56.35%). The proportion of female skiers (17.6%) with vigorous-intensity activity level was significantly lower than that of males (30.9%). Female skiers had lower body height, body weight, and body mass index than male skiers (P < 0.001). Conclusions ACL injury is the most common orthopaedic injury among both female and male knee-injured recreational skiers. The proportion of females with an ACL injury is higher than that of males, but the proportion of multiple knee ligament injuries is lower than that of males. More male recreational skiers have vigorous-intensity activity level habits in daily life than females.

Abstract
Background and aim The use of anti-inflammatory and analgesic drugs such as nonsteroidal anti-inflammatory drugs(NSAIDs) for treating acute gout has limitations, such as adverse reactions in the gastrointestinal tract and toxicity in the liver, kidney, and heart. Hence, a new safe and effective treatment approach needs to be explored to reduce the use of anti-inflammatory and analgesic drugs, incidence of adverse reactions, and patients’ burden. This randomized controlled clinical trial aimed to investigate the clinical efficacy and safety of the external application of compound Qingbi granules (CQBG) in treating acute gouty arthritis(AGA), providing evidence for designing a safe, effective, and optimized protocol for AGA comprehensive treatment. Methods A total of 90 patients in line with the diagnostic standard of AGA were recruited and randomly divided into control, T1, and T2 groups (30 in each group). All the participators in the three groups all received Western-medicine-basic treatment (low-purine diet, drinking water more than 2000 mL/days, oral loxoprofen, and NAHCO3). Besides, the T1 group received an external application of diclofenac diethylamine emulgel, while the T2 group received an external application of CQBG. The participants in the control group received single-use Western-medicine-basic treatment. With a treatment course of 7 days and a follow-up of 7 days, the three groups were compared in terms of primary outcome indicators, including swelling, pain improvement, and change in pain duration and secondary outcome indicators, including serum C-reactive protein (CRP) level, uric acid (UA) level, and change in the thickness of the inflammatory synovium of joints under ultrasound. Meanwhile, the safety of the protocol was evaluated. Results The three groups of patients had no apparent differences in age, body mass index, history of gout, complications, and so on before recruitment. A comparison between pretreatment and post-treatment revealed remarkable reductions in the arthralgia visual analog scale score(VAS) and the swelling score in the three groups after the treatment and the improvements in the T2 group were more significant than those in the T1 and control groups (P < 0.05). Regarding the onset time of pain improvement and pain duration, the T2 group had more significant efficacy compared with the other two groups (P < 0.05). The serum CRP and blood UA levels in the three groups significantly decreased after the treatment, but with no significant intergroup difference. The improvement in the thickness of the inflammatory synovium in joints tested by ultrasound was more significant in the T2 group than in the control group (P < 0.05). For safety evaluations, no significant difference in the incidence of adverse events was found. Conclusions The external application of CQBG combined with Western-medicine-basic treatment in patients with AGA improved arthralgia and swelling, shortened the period of taking NSAIDs, and reduced the levels of CRP and serum UA. Its therapeutic effect was significantly better than the effect of single-use Western-medicine-basic treatment. The study provided evidence for the clinical application of CQBG combined with Western medicine in treating AGA. Trial registration: ChiCTR, ChiCTR1800018020.

Abstract
Plant organellar RNA editing is a distinct type of post-transcriptional RNA modification that is critical for plant development. We showed previously that the RNA editing factor SlORRM4 is required for mitochondrial function and fruit ripening in tomato (Solanum lycopersicum). However, a comprehensive atlas of the RNA editing mediated by SlORRM4 is lacking. We observed that SlORRM4 is targeted to both chloroplasts and mitochondria, and its knockout results in pale-green leaves and delayed fruit ripening. Using high-throughput sequencing, we identified 12 chloroplast editing sites and 336 mitochondrial editing sites controlled by SlORRM4, accounting for 23% of chloroplast sites in leaves and 61% of mitochondrial sites in fruits, respectively. Analysis of native RNA immunoprecipitation sequencing revealed that SlORRM4 binds to 31 RNA targets; 19 of these targets contain SlORRM4-dependent editing sites. Large-scale analysis of putative SlORRM4-interacting proteins identified SlRIP1b, a RIP/MORF protein. Moreover, functional characterization demonstrated that SlRIP1b is involved in tomato fruit ripening. Our results indicate that SlORRM4 binds to RNA targets and interacts with SlRIP1b to broadly affect RNA editing in tomato organelles. These results provide insights into the molecular and functional diversity of RNA editing factors in higher plants.

Abstract
Abstract
Background:
Breast cancer is the most common malignancy in women worldwide and important therapeutic progress has been achieved over the past decade. The identification of new biomarkers in breast cancer is urgently needed to stratify populations who may benefit from new personalized therapies. Defects in the homologous recombination DNA damage repair (HR-DDR) pathway sensitizes tumors to therapeutics that target this pathway, such as (PARP) inhibitors. The aim of our study was to determine the prevalence of HR-DDR pathogenic mutations and their correlation with tumor mutation burden (TMB).
Materials and Methods:
Formalin-fixed, paraffin-embedded (FFPE) and matched blood samples of 328 Chinese breast cancer patients were collected for 450 cancer gene next-generation sequencing (NGS) targeted panel assay. Genomic alterations (GAs), including single base substitution, short and long insertion/deletions, copy number variations, gene fusions, and rearrangements, and TMB values were assessed with a mean coverage of 1000X. Samples with at least 1 GA in the HR pathway genes (ARID1A, ATM, ATR, ATRX, AURKA, BAP1, BARD1, BLM, BRCA1/2, BRIP1, CHEK1/2, FANCA/C/D2/E/F/G/L/M, MRE11A, NBN, PALB2, RAD50/1/1B/1C/1D/2, RAD54B/L, or WRN) were identified as HR-DDR deficient (HRD).
Results:
Our cohort included 326 females and 2 males with a median age of 49 years old. Molecular subtypes included HR+ (49%, n=161), HER-2+ (32.6%, n=107), and triple-negative breast cancer (TNBC) (18.2%, n=60). HR-DDR mutations were detected in 38.1% (125/328) of patients, and more than one mutation was found in 23 patients. The most commonly mutated genes included BRCA2 (7.31%), ARID1A (6.4%), BRCA1 (5.48%), AURKA (2.4%), and RAD50 (2.1%). No mutations were identified in genes of CHEK1, FANCE/F/G/L, MRE11A, RAD51/1B/1D, or RAD54L. HRD variations were enriched in 47.3% of stage IV cases, and only in 13.6% of cases at earlier stages (p<0.01). HRD mutations were not significantly associated with molecular subtypes, including HR+ (38.5%, n=62), HER-2+ (37.4%, n=40), and TNBC (38.3%, n=23). HRD cases had a higher median TMB than non-HRD cases (5.4 vs 3 muts/Mb, respectively, P <0.01). HRD-related germline mutations were found in 11.9% (39/328) of patients, and HR+ patients seemed to harbor more HRD-related germline mutations. BRCA1/2 mutations were the most frequent germline mutations (BRCA1, n=8; BRCA2, n=13). One patient had 2 germline mutations (BRCA2/FANCA).
Conclusions:
Our study revealed that HR-DDR mutations occurred in 38.1% of Chinese breast cancer patients, and BRCA2 was the most commonly mutated gene. HR-DDR mutations were associated with a higher TMB value, indicating a potential strategy for immunotherapy in Chinese breast cancer patients. The role of HRD-directed therapies, including poly-ADP ribose polymerase inhibitors and newer agents such as ATR inhibitors, needs to be explored.

Abstract
The normalcy index (NI) has been implemented by several studies as a simple index for quantitatively analyzing diffident gait abnormalities, such as children with cerebral palsy and idiopathic toe-walkers. However, whether the NI can be used in anterior cruciate ligament (ACL) deficiency with different types of meniscus injuries or not, has not been reported yet. In this study, 25 patients who combined different types of ACL and meniscus injuries were evaluated by the NI analysis. 12 healthy subjects were used to define the normal range of NI. The result showed that NI values of patients were significantly larger than the control group (P < 0.05). Meanwhile, the tendency of increasing NI values associated with increasing pathology were significant with only 5 subjects in the smallest group (Jonkheere-Terpsta test: P < 0.001). These results indicated that the NI was a concise yet effective tool to evaluate combined ACL and meniscus injury patients. Increasing severity degree of meniscus tears in ACL rupture patients is corresponded to increasing NI values. It also demonstrates that the proposed NI can be applied as a robustness factor to detect the discrepancy between healthy and patient subjects clinically, and has the potential in the quantitative evaluation of pre- or post-surgery and rehabilitation.

Abstract
Background: The posterior cruciate ligament (PCL) is an important structure in knee stabilization. Knee cartilage degeneration after a PCL injury has been reported in several studies. Understanding the changes in movement patterns of patients with PCL ruptures could help clinicians make specific treatment protocols to restore patients’ sporting ability and prevent joint degeneration. However, the kinematics and kinetics of the lower limb in patients with PCL injuries are still not clear. Purpose: To investigate the biomechanical characteristics during level walking in patients with isolated PCL deficiency. Study Design: Controlled laboratory study. Methods: Three-dimensional videographic and force plate data were collected for 27 healthy male participants (control group) and 25 male patients with isolated PCL-deficiency (PCL-d group) walking at a constant self-selected speed. Paired and independent t tests were performed to determine the differences between the involved and uninvolved legs in the PCL-d group and between the PCL-d and control groups, respectively. Results: Compared with the control leg, both legs in the PCL-d group had smaller knee moments of flexion and internal rotation; greater hip angles of flexion and adduction; greater hip moments of internal rotation; greater ankle angles of extension and adduction; and smaller ankle moments of flexion, adduction, and internal rotation. Moreover, compared with the uninvolved leg in the PCL-d group, the involved leg in the PCL-d group had significantly smaller knee extension angles and moments during the terminal stance phase, greater hip external rotation angles and extension moments, and smaller ankle adduction angles and flexion moments. Conclusion: PCL ruptures altered walking patterns in both the involved and uninvolved legs, which could affect alignment of the lower limb and loading on the knee, hip, and ankle joints. Patients with PCL injuries adapted their hip and ankle to maintain knee stability. Clinical Relevance: The kinematic and kinetic adaptations in the knee, hip, and ankle after a PCL rupture during level walking are likely to be a compensatory strategy for knee instability. The results of this study suggest that these adaptations should be considered in the treatment of patients with PCL ruptures.

Abstract
Background: Patients with anterior cruciate ligament–deficient (ACLD) knees with medial
meniscal posterior horn tears (MMPHTs) have been reported to demonstrate a
combined stiffening and pivot-shift gait pattern compared with healthy
controls. Movement asymmetries are implicated in the development and
progression of osteoarthritis. Purpose: To investigate the knee kinematics and kinetic asymmetries in ACLD patients
with (ACLD + MMPHT group) and without (ACLD group) MMPHTs while walking on
level ground. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 15 patients with isolated unilateral ACL ruptures, 10 with
unilateral ACL ruptures and MMPHTs, and 22 healthy controls underwent gait
testing between January 2014 and December 2016. Between-leg differences
(BLDs) in knee kinematics and kinetics were compared among participants in
all groups. Results: The ACLD + MMPHT group demonstrated significantly greater BLDs in knee
moments in the sagittal plane during the loading response phase than the
ACLD and control groups. Compared with the control group, the ACLD and ACLD
+ MMPHT groups demonstrated significantly greater BLDs in knee angles in the
sagittal plane during the midstance and terminal stance phases. Compared
with the control group, significantly greater BLDs in knee rotation moments
were found throughout the stance phase in both the ACLD and the ACLD + MMPHT
groups. BLDs in lateral ground-reaction forces (GRFs) in the ACLD + MMPHT
and ACLD groups were both significantly greater than the control group
during the loading response phase. BLDs in anterior GRFs in the ACLD + MMPHT
and ACLD groups were both significantly greater than the control group
during the loading response phase. Only the ACLD + MMPHT group demonstrated
greater BLDs in vertical GRFs than the control group during the loading
response phase, while no significant differences were observed between the
ACLD and control groups. Conclusion: The ACLD + MMPHT group demonstrated significantly more knee flexion moment
asymmetries than the ACLD and control groups during the loading response
phase. Both the ACLD + MMPHT and the ACLD groups demonstrated significant
knee angle and moment asymmetries in the sagittal plane during the terminal
stance phase than the control group. Both the ACLD + MMPHT and the ACLD
groups demonstrated knee rotation moment asymmetries during the midstance
and terminal stance phases compared with the control group. A rehabilitation
program for ACLD patients both with and without MMPHTs should take into
consideration these asymmetric gait patterns.

Abstract
An atom-efficient, straightforward method for the synthesis of 2,4,6-triaryl-1,3,5-triazines via iron-catalyzed cyclization of aldehydes with NH4I as the sole nitrogen source is demonstrated. This strategy works smoothly under air atmosphere, and affords symmetrical 2,4,6-trisubstituted and unsymmetrical 1,3,5-triazines with yields from 18% to 72%. Compared to other methods, the present protocol provides a straightforward and atom-efficient approach to 2,4,6-trisubstituted 1,3,5-triazines using an inexpensive, easily available ammonium salt as the sole nitrogen source. Research into the preliminary mechanism indicates that N-benzylidenebenzimidamides are involved in this cyclization reaction.

Abstract
Circulating miRNAs have been proposed as the effective diagnostic biomarkers for muscular fibrosis-associated diseases. However, circulating biomarkers for early diagnosis of contracture muscles are limited in gluteal muscle contracture (GMC) patients. Here we sought to explore the abnormally expressed miRNAs in plasma and contraction bands of GMC patients. The results showed miR-29a-3p expression in plasma and contraction bands tissue was significantly reduced in GMC patients compared with normal control. Cell viability and levels of proliferation-associated protein cyclin D1 and cyclin-dependent-kinase 2 (CDK2) were powerfully inhibited by miR-29a mimics and enhanced by miR-29a inhibitor compared with negative control. Furthermore, miR-29a mimics effectively impeded, while miR-29a inhibitor enhanced the expression of collagen I and collagen III, followed by the secretion of transforming growth factor beta1 (TGF-beta1), TGF-beta3 and connective tissue growth factor (CTGF) in primary human contraction bands (CB) fibroblasts. The miR-29a-3p negatively regulated the expression of TGF-beta1 through binding to the 3´ UTR region of SERPINH1 (encoding heat shock protein HSP47), but had no effect on Smad2 activity. The miR-29a-3p was inversely correlated with HSP47 in contraction bands tissue from GMC patients. Collectively, miR-29a was notably depressed and regulated cell viability and fibrosis by directly targeting HSP47 in GMC, which suggest that circulating miR-29a might be a potential biomarker for early diagnosis and provides a novel therapeutic target for GMC.

Abstract
Biomechanical risk factors associated with the alignment and position of the knee for anterior cruciate ligament (ACL) injury are still not conclusive. As bone bruises identified on magnetic resonance imaging (MRI) following acute ACL injury could represent the impact footprint at the time of injury. To improve understanding of the ACL injury mechanism, we aimed to determine the knee kinematics during ACL injury based on the bone bruises. Knee MRI scans of patients who underwent acute noncontact ACL injuries were acquired. Numerical optimization was used to match the bone bruises of the femur and tibia and predict the knee positions during injury. Knee angles were compared between MRI measured position and predicted position. The knee flexion, abduction, and external tibial rotation angles were significantly greater in the predicted position than that in MRI measured position. Relative to MRI measured position, patients had a mean of 34.3 mm of anterior tibial translation, 4.0 mm of lateral tibial translation, and 16.0 mm superior tibial translation in the predicted position. The results suggest that knee valgus and external tibial rotation accompanied by knee flexion are high-risk movement pattern for ACL injury in patients with lateral compartment bone bruising in conjunction with ACL injury.

Abstract
Acceleration of the anaerobic digestion (AD) process is crucial to achieving energy-efficient recycling of organic wastes. Hydrochar is produced by hydrothermal liquefaction of biomass, yet its application in the AD process is rarely reported. The present study showed that sewage sludge-derived hydrochar (SH) enhanced the methane production rate of glucose by 37%. SH increased the methane production rate from acetate but did not affect acidification and the methane production rate from H2/CO2. SH enhanced hydrogenotrophic methanogenesis, which could be due to direct interspecies electron transfer (DIET) by converting H+, e-, and CO2 to methane. Trichococcus and Methanosaeta were dominant in the AD process with SH. Label-free proteomic analysis showed Methanosaeta was involved in DIET as reflected by the up-regulation of proteins involved in hydrogenotrophic methanogenesis. Hydrochars derived from corn straw (CH), Enteromorpha algae (EH), and poplar wood (PH), as well as activated carbon (AC), were also tested in the AD process. SH, CH, and EH obviously increased the methane production rates, which were 39%, 15%, and 20% higher than the control experiment, respectively. It was neither electrical conductivity nor the total redox property of hydrochars and AC but the abundances of surface oxygen-containing functional groups that correlated to the methane production rates.

Abstract
Background Bone bruises observed on magnetic resonance imaging (MRI) after an anterior cruciate ligament (ACL) injury could provide significant information about ACL injury mechanisms. Purpose/Hypothesis The purpose of this study was to investigate common bone bruise patterns after an ACL injury. It was hypothesized that the most common bone bruise distribution pattern would be only the lateral side of both the femur and tibia. Study Design Cross-sectional study; Level of evidence, 3. Methods Knee MRI scans of patients who underwent acute ACL reconstruction from August 2016 to August 2018 at our institution were selected. Imaging sequences in the sagittal and coronal planes were used for determining the bone bruise location in the lateral-medial and anterior-posterior directions, respectively. The presence, location, and intensity of bone bruises within specific compartments of the tibia and femur were documented. The relative bone bruise patterns of the tibia and femur were classified and analyzed. Results A total of 207 patients (165 men, 42 women) met the inclusion criteria from a total of 4209 ACL reconstruction cases. The most common relative bone bruise pattern was located on only the lateral side of both the femur and the tibia (44.4%), followed by the lateral and medial sides of both the femur and tibia (29.0%). For the pattern found on the lateral and medial sides of both the femur and tibia, the bone bruises on only the lateral side of both the tibia and femur were more severe (P < .001 and P < .001, respectively) and more anterior (P < .001 and P < .001, respectively) than those on only the medial side. Conclusion The most common relative bone bruise pattern observed was on only the lateral side of both the tibia and femur. Bone bruises on the lateral side were more severe than those on the medial side in patients with bone bruises on the lateral and medial sides of both the femur and tibia. Anterior translation of the tibia relative to the femur occurred during an ACL injury based on the location of bone bruises in the anterior-posterior direction.
