Abstract
Recently a dark matter-electron (DM-electron) paradigm has drawn much attention. Models beyond the standard halo model describing DM accelerated by high energy celestial bodies are under intense examination as well. In this Letter, a velocity components analysis (VCA) method dedicated to swift analysis of accelerated DM-electron interactions via semiconductor detectors is proposed and the first HPGe detector-based accelerated DM-electron analysis is realized. Utilizing the method, the first germanium based constraint on sub-GeV solar reflected DM-electron interaction is presented with the 205.4 kg·day dataset from the CDEX-10 experiment. In the heavy mediator scenario, our result excels in the mass range of 5-15 keV/c^{2}, achieving a 3 orders of magnitude improvement comparing with previous semiconductor experiments. In the light mediator scenario, the strongest laboratory constraint for DM lighter than 0.1 MeV/c^{2} is presented. The result proves the feasibility and demonstrates the vast potential of the VCA technique in future accelerated DM-electron analyses with semiconductor detectors.

Abstract
Preparation from the aqueous alkoxide route of doped and co-doped lithium niobate nanocrystals with Er3+ and Yb3+ ions, and detailed investigations of their optical properties are presented in this comprehensive work. Simultaneous emission under femtosecond laser excitation of second harmonic generation (SHG) and up-conversion photoluminescence (UC-PL) is studied from colloidal suspensions according to the lanthanide ion contents. Special attention has been paid to produce phase pure nanocrystals of constant size (∼20 nm) thus allowing a straightforward comparison and optimization of the Er content for increasing the green UC-PL signals under 800 nm excitation. An optimal molar concentration at about 4 molar% in erbium ions is demonstrated, that is well above the concentration usually achieved in bulk crystals. Similarly, for co-doped LiNbO3 nanocrystals, different lanthanide concentrations and Yb/Er content ratios are tested allowing optimization of the green and red up-conversion excited at 980 nm, and analysis of the underlying mechanisms from excitation spectra. All together, these findings provide valuable insights into the wet-chemical synthesis and potential of doped and co-doped LiNbO3 nanocrystals for advanced applications, combining both SHG and UC-PL emissions from the particle core.

Abstract
It is unidentified whether information communication technology (ICT) agglomeration can contribute to carbon reduction and to what extent it plays a role in energy conservation and emission reduction, and further exploration is urgently needed. Based on the panel data of 108 cities in the Yangtze River Economic Belt from 2008 to 2019, the spatial panel Durbin model and intermediary effect model are employed to explore the effect of ICT agglomeration on carbon emissions and its pathways. It can be indicated from the results as below. (1) The local ICT agglomeration can reduce carbon emissions, but an increase in the level of ICT agglomeration in surrounding cities will increase local carbon emissions. (2) ICT agglomeration can reduce carbon emissions through reducing energy intensity and capital mismatch. (3) The effect of ICT agglomeration on carbon emissions is heterogeneous. ICT agglomeration can suppress carbon emissions in the middle and lower reaches of the Yangtze River, while it will increase carbon emissions in the upper reaches. ICT agglomeration increases carbon emissions in old industrial cities, reduces carbon emissions in non-old industrial cities, and has a more significant emission reduction effect in non-resource-based cities. We suggest promoting the formation of a coordinated linkage mechanism for ICT industry development and carbon emission reduction policies among regions, and implement differentiated ICT development strategies according to different industrial structure types.

Abstract
A 53-year-old female patient complained of 1 week of bilateral visual blurring. She was previously diagnosed with metastatic melanoma of the inguinal lymph nodes and treated with the oral targeted drug vemurafenib. She exhibited aqueous flare in the left eye, and her fundus examination revealed optic disc swelling in the left eye and bilateral serious detachment of the retinal neuroepithelial layer. Fluorescein angiography showed multiple pinpoint hyperfluorescence leakage spots in the prometaphase and appeared as multilobular dye pooling in the late phase. We diagnosed her as Vogt-Koyanagi-Harada syndrome and gave glucocorticoid treatment for eyes. Oral vemurafenib was also taken intermittently under the guidance of an oncologist. After treatment, her bilateral vision improved, the anterior segment inflammation disappeared, and the retinal neuroepithelial layer reattached, with presence of the "sunset glow" fundus.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:14801.

Abstract
Ecological welfare performance contributes directly to human well-being and regional sustainable development. Improving the regional ecological welfare performance in the process of pursuing green and sustainable development demands theoretical innovation and empirical exploration. Based on the super-efficiency SBM model, this study evaluated the ecological welfare performance of 108 cities during the period of 2009 to 2019. The Dagum Gini coefficient decomposition and spatial convergence model were employed to analyze the differences in ecological welfare performance across and within the study area and explore the underlining causes of such spatial differentiation in the Yangtze River Economic Belt and the upper, middle and lower reaches. It can be seen from the results that: (1) the overall difference in the ecological welfare performance of the Yangtze River Economic Belt is associated with a fluctuating downward trend during the study period. Regional and inter-regional differences were revealed and hypervariable density was identified as the main source of the differences. (2) The ecological welfare performance of the Yangtze River Economic Belt has absolute and conditional β convergence, and the ecological welfare performance of each city-region and surrounding urban areas has a positive impact on each other. (3) The difference in the spatial-temporal differentiation trend is manifested by the difference in the convergence rate. The cities in the middle reaches of the Yangtze River have the fastest convergence rate, followed by the cities in the upper reaches, and the cities in the lower reaches are the slowest. This geographic difference is mainly driven by the combined effects of industrial structure, urban characteristics, environmental regulation, foreign direct investment, and transportation accessibility. Finally, it is proposed that future policies should focus on the imbalanced regional development in the study area, and each region needs to explore ways to improve local ecological welfare performance according to local conditions, and ultimately promote the overall green, coordinated and high-quality development in the Yangtze River Economic Belt.

Abstract
Abstract
Introduction/Objective
Plasmacytoma is a discrete, solitary mass of neoplastic plasma cells. Extramedullary plasmacytoma (EMP) is a rare entity arising in tissues other than bone and it constitutes about 1% of all plasma cell neoplasms. Most cases of reported EMPs are in the upper aerodigestive tract (~80%). We present a very rare case with the initial presentation as an ovarian mass with metastasis into the peritoneal and pleural cavity.
Methods/Case Report
This is a 66-year-old female who presented with generalized abdominal pain, unexpected weight loss, and occasional fever and night sweats. Computed tomography (CT) scan of abdomen and pelvis showed an extensive metastatic disease including bilateral cardiophrenic angle lymphadenopathy, peritoneal spread encasing the bowel loops, bladder, and uterus as well as moderate right pleural effusion. The positron emission tomography (PET)-CT showed an ill-defined soft tissue density in the pelvis with hypermetabolism. The pelvic ultrasound showed a 2.6 x 2.2 x 1.1 cm hypoechoic mass in the left adnexa. The patient's serum cancer antigen (CA-125) was elevated at 123 U/mL and the post-thoracentesis chest x-ray was unremarkable with no acute osseous abnormalities. Other clinical data were not available.
Results (if a Case Study enter NA)
Cytopathologic evaluation of the pleural fluid showed abundant atypical cells with eccentrically located nuclei, scant to moderate cytoplasm with a paranuclear hof, frequent binucleation and mitoses. The cells ranged in size from small to large. Further immunohistochemical (IHC) analysis on the cell block showed that the tumor cells diffusely positive for CD138 and lambda light chain and negative for MOC31, BerEP4, calretinin, D2-40, WT1, HHV8, ALK1, and EBER in situ hybridization (ISH). The biopsy of the left adnexal mass showed a diffuse proliferation of tumor cells with frequent mitotic figures. The IHC analysis on the biopsy specimen showed tumor cells positive for CD79a and CD56 (weak) and negative for CD20 and PAX5. Kappa/lambda ISH analysis confirmed lambda light chain restriction of the tumor cells. These morphological and immunophenotypic features were consistent with plasma cell neoplasm.
Conclusion
The ovary is an unusual location to be involved by plasma cell neoplasm. We use this case to remind the pathologists and clinicians that ovarian plasmacytoma can be the initial presentation of the plasma cell neoplasm, although rare, and to aid the patients to receive an appropriate treatment. A thorough workup is needed to make an accurate diagnosis of this entity.

Abstract
OBJECTIVE The stability of fractures of the middle and lower 1/3 of the displaced humeral shaft is poor, and surgery is currently the main treatment. The posterolateral approach to the upper arm has many advantages but it is not widely used in clinical applications. The aim of the study was to investigate the clinical effect of open reduction and internal fixation with a steel plate through the triceps approach in the treatment of fractures of the middle and lower 1/3 of the humerus. PATIENTS AND METHODS A retrospective analysis was performed on 26 patients with fractures of the middle and lower 1/3 of the humerus who were admitted to our hospital from January 2018 to December 2021. According to the AO ASIF classification, 12 patients had type A, 8 patients had type B, and 6 patients had type C fractures. The posterior transtriceps approach was used for open reduction and internal fixation with a steel plate to evaluate its clinical efficacy. RESULTS All patients were followed completely, and the follow-up time was 6.0-18.0 months. Fracture nonunion occurred in 1 patient after the operation, and the other 25 patients healed well; 2 patients showed symptoms of radial nerve injury and numbness in the tiger's mouth area, which improved after 2 weeks. The average healing time of the fracture was 12.3 weeks. There were no infections or complications such as plate fractures. Elbow joint function according to Mayo scoring standards was as follows: 19 cases were excellent, 3 cases were good, 2 cases were fair, and 2 cases were poor. The excellent and good rate was 84.6%. CONCLUSIONS Open reduction through the triceps approach and internal fixation with a steel plate for the treatment of the middle and lower 1/3 of the humerus can directly expose and protect the radial nerve and its branches and reduce radial nerve damage, and plate fixation on the tension side is biomechanical and worthy of clinical application.

Abstract
The increased prevalence of temporomandibular joint osteoarthritis (TMJOA) in children and adolescents has drawn considerable attention as it may interfere with mandibular condyle growth, resulting in dento-maxillofacial deformities. However, treatments for osteoarthritis have been ineffective at restoring the damaged bone and cartilage structures due to poor understanding of the underlying degenerative mechanism. In this study, we demonstrate that Gli1+ cells residing in the subchondral bone contribute to bone formation and homeostasis in the mandibular condyle, identifying them as osteogenic progenitors in vivo. Furthermore, we show that, in a TMJOA mouse model, derivatives of Gli1+ cells undergo excessive expansion along with increased but uneven distribution of osteogenic differentiation in the subchondral bone, which leads to abnormal subchondral bone remodeling via Hedgehog (Hh) signaling activation and to the development of TMJOA. The selective pharmacological inhibition and specific genetic inhibition of Hh signaling in Gli1+ osteogenic progenitors result in improved subchondral bone microstructure, attenuated local immune inflammatory response in the subchondral bone, and reduced degeneration of the articular cartilage, providing in vivo functional evidence that targeting Hh signaling in Gli1+ osteogenic progenitors can modulate bone homeostasis in osteoarthritis and provide a potential approach for treating TMJOA.

Abstract
Purpose Most randomized controlled trials (RCTs) in patients with acute respiratory distress syndrome (ARDS) revealed indeterminate or conflicting study results. We aimed to systematically evaluate between-trial heterogeneity in reporting standards and trial outcome. Methods A systematic review of RCTs published between 2000 and 2019 was performed including adult ARDS patients receiving lung-protective ventilation. A random-effects meta-regression model was applied to quantify heterogeneity (non-random variability) and to evaluate trial and patient characteristics as sources of heterogeneity. Results In total, 67 RCTs were included. The 28-day control-group mortality rate ranged from 10 to 67% with large non-random heterogeneity (I2 = 88%, p < 0.0001). Reported baseline patient characteristics explained some of the outcome heterogeneity, but only six trials (9%) reported all four independently predictive variables (mean age, mean lung injury score, mean plateau pressure and mean arterial pH). The 28-day control group mortality adjusted for patient characteristics (i.e. the residual heterogeneity) ranged from 18 to 45%. Trials with significant benefit in the primary outcome reported a higher control group mortality than trials with an indeterminate outcome or harm (mean 28-day control group mortality: 44% vs. 28%; p = 0.001). Conclusion Among ARDS RCTs in the lung-protective ventilation era, there was large variability in the description of baseline characteristics and significant unexplainable heterogeneity in 28-day control group mortality. These findings signify problems with the generalizability of ARDS research and underline the urgent need for standardized reporting of trial and baseline characteristics.

Abstract
BACKGROUND AND PURPOSE The relationship between glycemic control in patients with type 2 diabetes mellitus and intracranial atherosclerotic plaque features has remained understudied. This study aimed to investigate the association of type 2 diabetes mellitus and glycemic control with the characteristics of intracranial plaques using vessel wall MR imaging. MATERIALS AND METHODS In total, 311 patients (217 [69.8%] men; mean age, 63.24 ± 11.44 years) with intracranial atherosclerotic plaques detected on vessel wall MR imaging were enrolled and divided into 3 groups according to type 2 diabetes mellitus and glycemic control statuses: the non-type 2 diabetes mellitus group, the type 2 diabetes mellitus with good glycemic control group, and the type 2 diabetes mellitus with poor glycemic control group. The imaging features of intracranial plaque were analyzed and compared among the groups. The clinical risk factors for atherosclerosis were also analyzed using logistic regression analysis. RESULTS The plaque length and thickness were significantly higher in the type 2 diabetes mellitus with poor glycemic control group than in the non-type 2 diabetes mellitus group. The prevalence of strongly enhanced plaques was significantly higher in the type 2 diabetes mellitus with poor glycemic control group than in the non-type 2 diabetes mellitus and type 2 diabetes mellitus with good glycemic control groups (92.9%, 63.4%, and 72.7%, respectively; P < .001). Multivariate logistic regression analysis showed a significant association of poor glycemic control with the plaque length (OR = 1.966; 95% CI, 1.170-3.303; P = .011), plaque thickness (OR = 1.981; 95% CI, 1.174-3.340; P = .010), and strongly enhanced plaque (OR = 5.448; 95% CI, 2.385-12.444; P < .001). CONCLUSIONS Poor glycemic control, compared with the history of diabetes, might have a greater impact on the burden and vulnerability of intracranial atherosclerotic plaques.

BACKGROUND Cardiovascular disease (CVD) was in common in coronavirus disease 2019 (COVID-19) patients and associated with unfavorable outcomes. We aimed to compare the clinical observations and outcomes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected patients with or without CVD. METHODS Patients with laboratory-confirmed SARS-CoV-2 infection were clinically evaluated at Wuhan Seventh People's Hospital, Wuhan, China, from 23 January to 14 March 2020. Demographic data, laboratory findings, comorbidities, treatments and outcomes were collected and analyzed in COVID-19 patients with and without CVD. RESULTS Among 596 patients with COVID-19, 215 (36.1%) of them with CVD. Compared with patients without CVD, these patients were significantly older (66 vs. 52 years) and had higher proportion of men (52.5% vs. 43.8%). Complications in the course of disease were more common in patients with CVD, included acute respiratory distress syndrome (22.8% vs. 8.1%), malignant arrhythmias (3.7% vs. 1.0%) including ventricular tachycardia/ventricular fibrillation, acute coagulopathy(7.9% vs. 1.8%) and acute kidney injury (11.6% vs. 3.4%). The rate of glucocorticoid therapy (36.7% vs. 25.5%), Vitamin C (23.3% vs. 11.8%), mechanical ventilation (21.9% vs. 7.6%), intensive care unit admission (12.6% vs. 3.7%) and mortality (16.7% vs. 4.7%) were higher in patients with CVD (both P < 0.05). The multivariable Cox regression models showed that older age (≥65 years old) (HR 3.165, 95% CI 1.722-5.817) and patients with CVD (HR 2.166, 95% CI 1.189-3.948) were independent risk factors for death. CONCLUSIONS CVD are independent risk factors for COVID-19 patients. COVID-19 patients with CVD were more severe and had higher mortality rate, early intervention and vigilance should be taken.

Abstract
OBJECTIVE To explore the effects of miR-21 on the rats with proliferative diabetic retinopathy by regulating the transforming growth factor-beta (TGF-β) signaling pathway. MATERIALS AND METHODS A total of 36 Sprague-Dawley rats were randomly divided into the normal group (n=12), model group (n=12), and inhibitor group (TGF-β signaling inhibitor) (n=12). No treatment was performed in the normal group, the diabetic retinopathy model was established in the model group, and the model was established in the inhibitor group after the intraperitoneal injection of the inhibitor. Then, the materials were sampled for detection. In each group, the retinal morphology was observed via hematoxylin-eosin (HE) staining, the expressions of TGF-β1 and Smad3 were detected via immunohistochemistry, the relative protein expression levels of phosphorylated Smad3 (p-Smad3) and TGF-β were determined via Western blotting, the expression of miR-21 was detected via quantitative Polymerase Chain Reaction (qPCR), and the hemodynamic indicators of the ocular tissues were detected using the color Doppler ultrasonography. RESULTS The HE staining results revealed that the rats in the model group had evident retinal damage, which could be effectively improved using the inhibitor. According to the immunohistochemistry detection results, the positive expression level of TGF-β1 was substantially raised in both model group and inhibitor group compared with that in the normal group (p<0.05), and it was notably lower in the inhibitor group than that in the model group (p<0.05). Moreover, the three groups did not differ in the positive expression level of Smad3 (p>0.05). The Western blotting results showed that the model and inhibitor groups had remarkably higher relative protein expression levels of p-Smad3 and TGF-β1 than the normal group (p<0.05), and they were markedly lowered in the inhibitor group compared with those in the model group (p<0.05). According to the qPCR results, the expression level of miR-21 was notably elevated in both model group and inhibitor group compared with that in the normal group (p<0.05), and there was no difference in the expression level of miR-21 between the former two groups (p>0.05). Finally, based on the color Doppler ultrasonography findings, the levels of the hemodynamic indicators substantially declined in both model group and inhibitor group compared with those in the normal group (p<0.05), and they were notably higher in the inhibitor group than those in the model group. CONCLUSIONS We found that miR-21 regulates the TGF-β signaling pathway to affect the hemodynamics in the rats with proliferative diabetic retinopathy.

Abstract
Increasing researches have focused on the biological functions of long noncoding RNAs (lncRNAs) in human cancers. HOXA11-AS, a widely known lncRNA, has been confirmed to be involved in the progression of several cancers, including gastric cancer (GC). Whereas, the detailed mechanism of this lncRNA in GC remains to be further illuminated. The abundances of HOXA11-AS, miR-148a and WNT1 in GC tissues and cell lines were examined by qRT-PCR. Clinicopathological and Kaplan-Meier survival analyses were determined to explore the relationship between HOXA11-AS expression and outcomes of patients. Transwell assay was performed for the evaluation of cell migration and invasion. Bioinformatics, dual-luciferase reporter and RNA immunoprecipitation assays were employed to analyze the correlation between HOXA11-AS and miR-148a or miR-148a and WNT1. The protein levels of WNT1 and β-catenin were assessed by western blot assay. Results showed that HOXA11-AS and WNT1 expression levels were upregulated, while miR-148a level was downregulated in GC tissues and cell lines relative to matched controls. Elevated expression of HOXA11-AS was associated with increased tumor size, lymph node metastasis, advanced TNM stage, as well as reduced survival of GC patients. HOXA11-AS induced migration and invasion of GC cells through serving as a molecular sponge for miR-148a. Furthermore, miR-148a inactivated WNT1/β-catenin signaling pathway via directly targeting WNT1. HOXA11-AS increased WNT1/β-catenin pathway activity, which was abolished by miR-148a overexpression in GC cells. In conclusion, overexpression of HOXA11-AS contributed to migration and invasion of GC cells via activation of WNT1/β-catenin signaling pathway through repressing miR-148a, providing a prospective therapeutic target for GC.

Abstract
OBJECTIVE As a kind of malignant tumor in the male genitourinary system, prostate cancer exhibits significantly increased occurrence. Prostate-specific antigen (PSA) expression can be seen in the prostate cancer, prostatitis, and other diseases, therefore, lack of diagnostic specificity. The miR-155 expression is abnormally increased in the tumors. Therefore, this study aims to explore the clinical significance of PSA combined miR-155 detection in the early diagnosis of prostate cancer. PATIENTS AND METHODS A total of 86 patients diagnosed with prostate cancer were enrolled in this study. PSA and miR-155 gene expression in tumor tissue were detected by using Real-time PCR. The serum levels of PSA were measured by using enzyme-linked immunosorbent assay (ELISA). The correlation of PSA and miR-155 expression with age, body mass index (BMI), tumor volume, tumor-node-metastasis (TNM) stage, lymph node metastasis (LNM), and other clinicopathological features were analyzed, respectively. RESULTS Serum PSA expression and PSA gene in tumor tissue were significantly higher compared to that in adjacent tissues (p<0.05). PSA gene and protein increased significantly with the clinical stage of TNM and decreased following the increase of grade (p<0.05). The miR-155 level was significantly elevated in the tumor tissue compared with para-carcinoma tissue (p<0.05). PSA and miR-155 expressions were positively correlated with TNM stage, tumor volume, and LNM, and negatively correlated with grade (p<0.05). CONCLUSIONS PSA and miR-155 were closely related to the clinicopathological features of prostate cancer. Combined detection is helpful for the early diagnosis of prostate cancer.
