To develop an alarm device for the mechanical compression device displacement (MCD), and further evaluate its effectiveness in clinical use. The alarm device is mainly composed of buzzer, indicator light, magnetic sheet. This is a prospective randomized and controlled study. Four hundred patients who met the inclusion/exclusion criteria were included and randomly assigned to two groups (MCD group vs alarm + MCD group). The primary outcome measures were the sensitivity and specificity of the alarm device to detect MCD displacement, time to hemostasis (TTH), time to ambulation (TTA), time to hospital discharge (TTHD), hospital costs (HC), complication rates, and patient satisfaction. The sensitivity and specificity of the alarm device in detecting MCD displacement were 94.44% and 88.46%, respectively. The study group achieved shorter TTH (p =.034), shorter TTA (p =.021), lower complication rates (p =.025), and better patients' satisfaction (p <.001) compared to the control group. However, no significant difference was observed in TTHD (p =.361) and HC (p =.583). The alarm device is highly sensitive in detecting MCD displacement, while achieving better clinical outcomes compared with artificial monitoring. [ABSTRACT FROM AUTHOR]

Background: The introduction of multiparameter MRI and novel biomarkers has greatly improved the prediction of clinically significant prostate cancer (csPCa). However, decision-making regarding prostate biopsy and prebiopsy examinations is still difficult. We aimed to establish a quick and economic tool to improve the detection of csPCa based on routinely performed clinical examinations through an automated machine learning platform (AutoML). Methods: This study included a multicenter retrospective cohort and two prospective cohorts with 4747 cases from 9 hospitals across China. The multimodal data, including demographics, clinical characteristics, laboratory tests, and ultrasound reports, of consecutive participants were retrieved using extract-transform-load tools. AutoML was applied to explore potential data processing patterns and the most suitable algorithm to build the Prostate Cancer Artificial Intelligence Diagnostic System (PCAIDS). The diagnostic performance was determined by the receiver operating characteristic curve (ROC) for discriminating csPCa from insignificant prostate cancer (PCa) and benign disease. The clinical utility was evaluated by decision curve analysis (DCA) and waterfall plots. Results: The random forest algorithm was applied in the feature selection, and the AutoML algorithm was applied for model establishment. The area under the curve (AUC) value in identifying csPCa was 0.853 in the training cohort, 0.820 in the validation cohort, 0.807 in the Changhai prospective cohort, and 0.850 in the Zhongda prospective cohort. DCA showed that the PCAIDS was superior to PSA or fPSA/tPSA for diagnosing csPCa with a higher net benefit for all threshold probabilities in all cohorts. Setting a fixed sensitivity of 95%, a total of 32.2%, 17.6%, and 26.3% of unnecessary biopsies could be avoided with less than 5% of csPCa missed in the validation cohort, Changhai and Zhongda prospective cohorts, respectively. Conclusions: The PCAIDS was an effective tool to inform decision-making regarding the need for prostate biopsy and prebiopsy examinations such as mpMRI. Further prospective and international studies are warranted to validate the findings of this study. Trial registration: Chinese Clinical Trial Registry ChiCTR2100048428. Registered on 06 July 2021.

The COVID-19 pandemic increases the risk of psychological problems including suicidal ideation (SI) in the general population. In this study, we investigated the risk factors of SI after the COVID-19 pandemic was initially controlled in China. We conducted an online questionnaire via JD Health APP in China in June 2020. Demographic data, feelings and experiences related to the COVID-19 pandemic and psychological problems were collected. The participants (n = 14,690) were divided into the non-SI and SI groups. A binary logistic regression analysis was used to examine the correlates of SI. Nine percent of the participants (1328/14690) reported SI. The regression analysis showed that SI was positively associated with ethnic minority (OR = 1.42 [1.08–1.85]), age (e.g. 18–30 years: OR = 2.31 [1.67–3.20]), having history of mental disorders (OR = 2.75 [2.27–3.35]), daily life disturbance due to health problems (OR = 1.67 [1.38–2.01]), being around someone with the COVID-19 (OR = 1.58 [1.30–1.91]), being uncertain about effective disease control (OR = 1.23 [1.03–1.46]), and having depressive symptoms (OR = 4.40 [3.59–5.39]), insomnia symptoms (OR = 2.49 [2.13–2.90]) or psychological distress (OR = 1.87 [1.59–2.18]). The main limitation is that the cross-sectional design of this study could not allow us to further explore the causality of SI. The prevalence of SI was relatively high in general population after the COVID-19 pandemic was initially controlled in China. SI should be monitored continually after the COVID-19 pandemic. [Display omitted] • The rate of SI was still high after the COVID-19 pandemic was initially controlled. • Multiple factors were associated with suicidal ideation after the COVID-19 pandemic was initially controlled. • Mental health and SI should continue to be monitored after the COVID-19 pandemic.

Simple Summary: We performed transcriptome sequencing of the ovaries and testis of T. blochii to acquire sex-biased miRNAs. RNA-seq analysis yielded 1366 known and 69 novel miRNAs with 289 significant DEMs (p < 0.05). KEGG analysis indicated that the target genes of the DEMs were mainly enriched in pathways connected to sex differentiation and gonadal development signals, consisting of the MAPK signaling pathway, Wnt signaling pathways, and steroid biosynthetic pathways. Co-expression network analysis of miRNA-mRNA indicated that some miRNAs (oar-let-7b, bta-miR-2898, pma-miR-138b, and novel-176) may play crucial roles in gonadal development in T. blochii. Our research identified a set of sex-biased miRNAs that might be regulatory factors affecting gonadal development in T. blochii. This provides new insight and may further our understanding the role of miRNAs in gonadal development of this economically valuable species. The golden pompano (Trachinotus blochii) is a marine fish of considerable commercial importance in China. It shows notable sexual size dimorphism; the growth rate of females is faster than that of males. Therefore, sex-biased research is of great importance in T. blochii breeding. However, there have been few studies on sex differentiation and mechanisms underlying sex determination in T. blochii. MicroRNAs (miRNAs) play crucial roles in sex differentiation and determination in animals. However, limited miRNA data are available on fish. In this study, two small RNA libraries prepared from the gonads of T. blochii were constructed and sequenced. The RNA-seq analysis yielded 1366 known and 69 novel miRNAs with 289 significantly differentially expressed miRNAs (p < 0.05). Gene ontology (GO) analysis confirmed that the TFIIA transcription factor complex (GO: 0005672) was the most significantly enriched GO term. The Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis showed that the differentially expressed miRNAs and target genes were mainly related to sex determination and gonadal developmental signaling pathways, specifically the Wnt signaling pathway, MAPK signaling pathway, and steroid biosynthetic pathway. MiRNA-mRNA co-expression network analysis strongly suggested a role for sex-biased miRNAs in sex determination/differentiation and gonadal development. For example, gata4, foxo3, wt1, and sf1 genes were found to be regulated by bta-miR-2898; esr2 and foxo3 by novel_176, and ar by oar-let-7b. Quantitative real-time polymerase chain reaction analysis of selected mRNAs and miRNAs validated the integrated analysis. This study established a set of sex-biased miRNAs that are potential regulatory factors in gonadal development in T. blochii. These results provide new insight into the function of miRNAs in sex differentiation and determination in T. blochii and highlight some key miRNAs for future studies. [ABSTRACT FROM AUTHOR]

Tetratrichomonasgallinarum and Trichomonas gallinae can colonize the alimentary tract of domestic birds. However, little information is available on the epidemiology of the two trichomonad species in domestic free-range poultry in China. In this study, the occurrence and genetic characteristic of T. gallinarum and T. gallinae among free-range chickens, ducks, and geese in Anhui Province, China, were investigated. The 1910 fecal samples collected from 18 free-range poultry farms throughout Anhui Province were examined for the presence of T. gallinarum and T. gallinae by PCR and sequence analysis of the small subunit (SSU) rRNA gene of T. gallinarum and ITS1-5.8S-ITS2 sequence of T. gallinae. The overall occurrence of T. gallinarum in poultry was 1.2% (22/1910), with infection rates of 2.1% (17/829) in chickens, 0.2% (1/487) in ducks, and 0.7% (4/594) in geese. The constructed phylogeny tree using the concatenated ITS1-5.8S-ITS2 region and SSU rRNA indicated the T. gallinarum isolates detected in this study were closely related to previously defined genogroups A, D, and E, respectively. Nine (0.5%) fecal samples were positive for T. gallinae, with infection rates of 0.8% (7/829) in chickens, 0.4% (2/487) in ducks, and 0% (0/594) in geese. Sequence and phylogenetic analysis showed that four T. gallinae ITS1-5.8S-ITS2 sequences obtained from chicken feces and one duck fecal sample belonged to genotype ITS-OBT-Tg-1. This is the first report of the prevalence and genetic characterization of T. gallinarum and T. gallinae in free-range chickens, ducks, and geese in China. [ABSTRACT FROM AUTHOR]

Pompano fishes have been widely farmed worldwide. As a representative commercial marine species of the Carangidae family, the golden pompano (Trachinotus blochii) has gained significant popularity in China and worldwide. However, because of rapid growth and high-density aquaculture, the golden pompano has become seriously threatened by various diseases. Cell lines are the most cost-effective resource for in vitro studies and are widely used for physiological and pathological research owing to their accessibility and convenience. In this study, we established a novel immortal cell line, GPF (Golden pompano fin cells). GPF has been passaged over 69 generations for 10 months. The morphology, adhesion and extension processes of GPF were evaluated using light and electron microscopy. GPF cells were passaged every 3 days with L-15 containing 20 % fetal bovine serum (FBS) at 1:3. The optimum conditions for GPF growth were 28 °C and a 20 % FBS concentration. DNA sequencing of 18S rRNA and mitochondrial 16S rRNA confirmed that GPF was derived from the golden pompano. Chromosomal analysis revealed that the number pattern of GPF was 48 chromosomes. Transfection experiments demonstrated that GPF could be utilized to express foreign genes. Furthermore, heavy metals (Cd, Cu, and Fe) exhibited dose-dependent cytotoxicity against GPF. After polyinosinic-polycytidylic acid (poly I:C) treatment, transcription of the retinoic acid-inducible gene I-like receptor (RLR) pathway genes, including mda5 , mita , tbk1 , irf3 , and irf7 increased, inducing the expression of interferon (IFN) and anti-viral proteins in GPF cells. In addition, lipopolysaccharide (LPS) stimulation up-regulated the expression of inflammation-related factors, including myd88 , irak1 , nfκb , il1β , il6 , and cxcl10 expression. To the best of our knowledge, this is the first study on the immune response signaling pathways of the golden pompano using an established fin cell line. In this study, we describe a preliminary investigation of the GPF cell line immune response to poly I:C and LPS, and provide a more rapid and efficient experimental material for research on marine fish immunology. • GPF was established and became a stable fin cell line of Trachinotus blochii. • GPF can be used to assess the cytotoxicity of heavy metals. • GPF can be utilized to express foreign genes with 32 % transfection efficiency. • GPF's immune response to LPS and poly I: C challenge proved it can be used for in vitro immunology study.

Image classification aims to automatically group a set of images into several categorizations, which is widely applied in scene categorization, image clustering. Lung cancer recognition can be achieved by using image classification technique, since there are distinct differences between healthy lung and sick lung images. In this paper, we propose lung cancer recognition based on image quality assessment, which can distinguish sick lung images from healthy lung images. First, our dataset is acquired using low-dose CT scan combined with full-mode iterative recombination (IMR). Then, we incorporate both low-level and high-level features to extract deep representation from obtained dataset. Specifically, our designed low-level features include color moment and texture feature, and CNN based method is leveraged for deep feature extraction. For reducing artifacts and noise of images, we assign quality score for each training image. And quality score and deep feature are fused to generate deep representation. Afterward, we propose a probabilistic model to learn the distribution of deep representation. Finally, lung cancer recognition can be achieved using learned model. We conduct comprehensive experiments and our proposed method is verified effective. [ABSTRACT FROM AUTHOR]

• Lignin stabilization was achieved by aggregate protection in broadleaf-pine forest. • Lignin accumulation was enhanced by plant residues input in broadleaf forest. • High macroaggregate proportion did not support great SOC sequestration in broadleaf forest. The variation of soil organic carbon (SOC) stability is independent of the amount of SOC in the soil. For predicting the conservation of soil carbon in different forest ecosystems, it is crucial to investigate the mechanisms of plant derived residues allocation and stabilization in soil aggregates in different forest ecosystems. The role of aggregate protection in SOC sequestration (using lignin as a biochemical indicator) requires understanding of the interaction of many factors. We studied aggregate proportion, SOC amount and lignin phenol contents in the soil fractions from 0–5, 5–10 and 10–20 cm layers in a virgin mixed broadleaf-Korean pine (BK) and secondary broadleaf Betula-Populus (BP) stands at Changbai Mountain Nature Reserve, Northeastern China. Macroaggregates had higher lignin contents compared to the bulk soil in both BK and BP. The SOC and lignin contents in bulk soil and aggregates obviously declined with soil deepening in the two stands. BK exhibited more protected lignin in aggregates compared to the same particles from BP. The results suggested that the aggregates have limited capability to sequestrate more carbon, which causes carbon loss in the soil particles with soil depth increment in the secondary broadleaf forest. Stable lignin sequestration was achieved via effective aggregate protection in BK, while lignin occlusion was mainly regulated by the importation of plant residues into the topsoil of BP.

Background: The purpose of this study was to assess the clinical outcome of percutaneous kyphoplasty (PKP) assisted with mixed reality (MR) technology in treatment of osteoporotic vertebral compression fracture (OVCF) with intravertebral vacuum cleft (IVC). Method: Forty cases of OVCF with IVC undergoing PKP were randomized into a MR technology-assisted group (group A) and a traditional C-arm fluoroscopy group (group B). Both groups were performed PKP and evaluated by VAS scores, ODI scores, radiological evidence of vertebral body height, and kyphotic angle (KA) at pre-operation and post-operation. The volume of injected cement, fluoroscopy times, and operation time were recorded. And cases of non-PMMA-endplates-contact(NPEC) in radiological evidence was also recorded postoperatively. The clinical outcomes and complications were evaluated afterwards. All patients received 10 to 14 months follow-up, with an average of 12 months. Result: This MR-assisted group (group A) acquired more about the amount of the polymethyl methacrylate (PMMA) injection and postoperative vertebral height and less about postoperative KA, fluoroscopy times, and operation time compared with the control group (group B) (P < 0.05). The VAS scores and ODI scores in both groups have improved, but more significantly in group A (P < 0.05). Also, more cases achieve both-endplates-touching of cement in group A (P < 0.05). And there are less of the loss of vertebral height, KA, and occurrence of re-collapse of the vertebra in group A during the follow-up (P < 0.05). Conclusion: PKP assisted with MR technology can accurately orientate the position of IVC area, which can be augmented by the balloon leading to more satisfied vertebral height improvement, cement diffusion, and pain relief.
