ABSTRACT

Purpose@#To generate the under-sampling pattern using a self-supervised learning framework based on a graph convolutional network. @*Materials and Methods@#We first decoded the k-space data into the graph and put it into the network. After the processing of graph convolution layers and graph pooling layers, the network generated the under-sampling pattern for MR reconstruction.We trained the network on the simulated brain dataset enabled by the selfsupervised learning strategy. We did simulation along with the in vivo brain and liver experiments under different noise levels and accelerating factors to compare the performance between the proposed method and traditional methods using the PSNR and SSIM index. @*Results@#The simulation experiments showed that the proposed method can achieve the best performance with low accelerating factors (2 and 3) at all noise levels and in high accelerating factors (4 and 5) at high noise levels (50 and 70 dB). In in vivo experiments, the proposed method attained the highest PSNR and SSIM in the brain dataset as well as in the liver dataset after fine tuning on a small liver dataset. @*Conclusion@#The self-supervised learning framework based on a graph convolutional network was able to design the under-sampling mask for MR reconstruction. The superior performance in the simulation and in vivo experiments demonstrated the feasibility and flexibility of the proposed method and its potential in clinical use.

ABSTRACT

We hereby reported the diagnosis, treatment process and perinatal outcome of a patient with novel coronavirus infection in perinatal period. The pregnant woman delivered a boy by cesarean section at 37+2 gestational weeks due to severe liver dysfunction. She subsequently had a high fever 2 days later, and novel coronavirus infection was confirmed by nucleic acid test in a throat swab. After a 12-day isolation and support treatment, her two consecutive throat swab results for novel coronavirus turned negative and she was discharged. The novel coronavirus was tested in the patient's blood, urine, breast milk as well as the neonatal throat swab, and the results were all negative. The neonate had an elevated myocardial enzyme, but was otherwise well and was discharged after 14-day isolation with normal myocardial enzyme.

ABSTRACT

Objective:To fully understand the maternal and neonatal outcomes in pregnant women with COVID-19 and explore the evidence of intrauterine vertical transmission of 2019-nCoV by analyzing clinical and laboratory information in peer-reviewed publications on COVID-19 in pregnant women.Methods:PubMed, Embase, China National Knowledge Infrastructure, China Academic Journals, and Wanfang Databases were searched to retrieve articles on COVID-19 in pregnancy published from December 1, 2019, to April 9, 2020. In addition, the World Health Organization COVID-19 Database and the reference lists in each included article were also searched. All included cases were positive for 2019-nCoV nucleic acid with maternal and neonatal outcomes regardless of delivery or not. Clinical manifestations, perinatal and neonatal outcomes were analyzed systematically.Results:This study reviewed 29 publications involving 146 pregnant women who tested positive for 2019-nCoV nucleic acid and their 116 newborns (including two twins). Five cases of severe COVID-19 and three cases of unidentified type that were admitted to ICU for treatment were severe symptoms, accounting for 5.5% (8/146) of all cases. Totally, 69.9% (102/146) of the women underwent cesarean section and 8.2% (12/146) gave birth vaginally. Thirty (20.5%) women continued their pregnancies. One case (0.7%, 1/146) terminated the pregnancy at 26 weeks of gestation due to bidirectional affective disorder and one (0.7%, 1/146) received artificial abortion at 6 weeks of gestation. Fever (58.2%, 85/146) and cough (32.9%, 48/146) were the most common symptoms. However, 15.8% (23/146) of the pregnant women were asymptomatic on admission and symptoms appeared or became worse after delivery in 20.5% (30/146). Lymphocytopenia (49.6%, 56/113) and elevated C-reactive protein (58.4%, 66/113) were the main laboratory findings. The most common computed tomography (CT) finding was bilateral multiple patchy ground-glass opacity in lungs (79.7%, 94/118). The outcomes of 92.2% (107/116) of the newborns were good, and the rest 7.8% (9/116) showed different abnormalities of varying degrees. Among the nine newborns, six showed different degrees of dyspnea, cyanosis and vomiting including one died of multiple organ failure and disseminated intravascular coagulation; one tested positive for viral nucleic acid 36 hours after birth; one was stillbirth due to unknown reason, but intrauterine vertical transmission was excluded; one neonatal death in a critically ill mother undergoing cesarean delivery.Conclusions:Pregnant women are less likely to progress to severe COVID-19 and mostly have a good outcome. Despite reports of adverse neonatal outcomes, evidence of intrauterine vertical transmission of 2019-nCoV remains insufficient.

ABSTRACT

Purpose To investigate the value of simultaneousnon-contrast angiographyand intra-plaquehemorrhage (SNAP) in assessing Willis circle integrity of the brain using three-dimensional time of flight (TOF) MRA as a reference. Materials and Methods According to the inclusion criteria, a total of 62 patients with stroke symptoms within 3 months were collected. All patients underwent head SNAP and TOF on Philips 3.0T MR scanner. TOF and SNAP were treated respectively at the Philips workstation using maximum and minimum intensity projections to generate non-enhanced MRA images which were, afterwards, interpreted using blind reading to determine the presence or absence of individual blood vessels in the circle of Willis. In order to assess the consistency of the interpretation, all images were interpreted again 2 weeks later to avoid memory bias. Finally, The consistency of the two interpretations was analyzed, and the ability of SNAP and TOF in evaluating the integrity of Willis circle was compared. In addition, for 15 patients with VISTA images, the plaque of Willis circle vascular wall was evaluated using SNAP and VISTA images to compare their evaluation ability. Results The results of the first and second interpretations of SNAP and TOF were highly consistent. The arteries with exactly the same interpretation included left anterior cerebral artery A1 (LA1), right anterior cerebral artery A1 (RA1), left posterior cerebral artery P1 (LP1) and right posterior cerebral artery P1 (RP1) (Kappa=1.000). The results in terms of left posterior communicating artery (LPCoA) (Kappa=0.926 and 0.924, respectively), right posterior communicating artery (RPCoA) (Kappa=0.931 and 0.732, respectively) and integrity (Kappa=0.815 and 0.816, respectively) were relatively consistent, while there was a relatively low consistency in terms of anterior communicating artery (ACoA) (Kappa=0.640 and 0.675, respectively). In evaluating the constituent vessels of the circle of Willis and its integrity, SNAP and TOF showed good consistency. Vessels with identical SNAP and TOF interpretations include LA1, RA1, LP1, and RP1 (Kappa=1.000). The interpretation consistency of the two imaging techniques on LPCoA (Kappa=0.852 and 0.848), RPCoA (Kappa=0.796 and 0.796, respectively), and integrity (Kappa=0.701 and 0.742, respectively) was relatively high. While the consistency of SNAP and TOF in terms of ACoA was slightly lower (Kappa=0.680 and 0.714, respectively). In assessing the plaque of Willis circle vascular wall, the evaluation results of SNAP and VISTA were consistent. Conclusion As a non-enhanced angiography technique, the magnetic resonance SNAP sequence can well evaluate the integrity of Willis circle, as well as the presence or absence of plaque on Willis circle vascular wall.

ABSTRACT

Exploiting cells as vehicles combined with nanoparticles combined with therapy has attracted increasing attention in the world recently. Red blood cells, leukocytes and stem cells have been used for tumor immunotherapy, tissue regeneration and inflammatory disorders, and it is known that neutrophils can accumulate in brain lesions in many brain diseases including depression. -Acetyl Pro-Gly-Pro (PGP) peptide shows high specific binding affinity to neutrophils through the CXCR2 receptor. In this study, PGP was used to modify baicalein-loaded solid lipid nanoparticles (PGP-SLNs) to facilitate binding to neutrophils . Brain-targeted delivery to the basolateral amygdala (BLA) was demonstrated by enhanced concentration of baicalein in the BLA. An enhanced anti-depressant effect was observed and The mechanism involved inhibition of apoptosis and a decrease in lactate dehydrogenase release. Behavioral evaluation carried out with rats demonstrated that anti-depression outcomes were achieved. The results indicate that PGP-SLNs decrease immobility time, increase swimming time and climbing time and attenuate locomotion in olfactory-bulbectomized (OB) rats. In conclusion, PGP modification is a strategy for targeting the brain with a cell-nanoparticle delivery system for depression therapy.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the mechanisms of lysophosphatidic acid (LPA) in stimulating invasion and metastatic colonization of ovarian cancer cells.</p><p><b>METHODS</b>The metastatic ability in vivo of ovarian cancer SK-OV3, HEY, OVCAR3, and IGROV1 cells was determined in tumor-bearing nude mouse models. Matrigel assay was used to detect the changes of response in vitro of ovarian cancer cells to LPA after Rac(-) or Rac(+) adenovirus treatment. LPA-induced Rho GTPase activation was detected by GST-fusion protein binding assay.</p><p><b>RESULTS</b>The peritoneal metastatic colonization assay showed overt metastatic colonization in mice receiving SK-OV3 and HEY cell inoculation, indicating that they are invasive cells. Metastatic colonization was not detected in animals receiving OVCAR3 and IGROV1 cells, indicating that these cells are non-invasive cells. In the matrigel invasion assay, exposure to LPA led to a notably greater migratory response in metastatic SK-OV3 and HEY cells (Optical density: SK-OV3 cells: 0.594±0.023 vs. 1.697±0.049, P<0.01; HEY cells: 0.804±0.070 vs. 1.851±0.095, P<0.01). But LPA did little in the non-metastatic OVCAR3 and IGROV1 cells (Optical density A: OVCAR3 cells: 0.336±0.017 vs. 0.374±0.007, P>0.05; IGROV1 cells: 0.491±0.036 vs. 0.479±0.061, P>0.05). LPA migratory responses of ovarian cancer cells were closely related to their metastatic colonization capabilities (r = 0.983, P<0.05). Rac(-) blocked the LPA response of invasive SK-OV3 and HEY cells (LPA-induced fold increase of cell migration: SK-OV3 cells: 2.988±0.095 vs. 0.997±0.100,P=0.01; HEY cells: 2.404±0.059 vs. 0.901±0.072, P=0.01). But Rac(+) confered the non-invasive cells with LPA response and invasion capability (LPA-induced fold increase of cell migration: OVCAR3 cells: 1.072±0.080 vs. 1.898±0.078, P<0.01; IGROV1 cells: 1.002±0.044 vs. 2.141±0.057, P<0.05). Among Rho GTPases, only Rac activation was different between ovarian cancer cell lines with different metastatic capability after LPA stimulation: Cdc42 could not be activated in both the invasive and non-invasive cell lines. RhoA could be activated in both the invasive and non-invasive cell lines. Rac could be activated by LPA in the invasive ovarian cancer cell lines. However, Rac could not be activated in the non-invasive cell lines.</p><p><b>CONCLUSION</b>Lysophosphatidic acid stimulates invasion and metastasis of ovarian cancer cells through Rac activation.</p>

ABSTRACT

Neonatal hypoglycemia is a common metabolic problem. The definition and clinical management of neonatal hypoglycemia remains controversial. The concerned reasons are mainly as follows:the course of a physiological decrease and recovery in the level of blood glucose is usually existed in newborn infants after birth;asymptomatic hypoglycemia(many newborn infants' blood glucose level is very low but without any clinical signs or symptoms);and the lack of the complete comprehension for the relationship between neonatal hypoglycemia and the long-term neurologic prognosis. The review describes the etiology,definition and clinical management of hypoglycemia in newborn infants.

ABSTRACT

Objective To determine the expression of phosphatidyhnositol 3-kinase (PI3K), phosphorylated protein kinase B (P-AKT) and protein kinase B (AKT) in cervical cancer and explore the correlations with the genesis and development of cervical cancer. Methods Western blot was used to detect the expression of PI3K, P-AKT and AKT proteins in 66 cases of cervical tissues, including 33 cervical cancers, 23 cervical intraepithelial cancer, 10 normal cervical tissues, and analyzed the clinical significances according to clinical informations. Results In cervical cancers, cervical intraepithelial cancer and normal cervical tissues, the expression of PI3K protein were 1.3880±0.0435, 0.5330±0.0939, 0.2427±0.0888 and had significant differences among them, but there was no significant difference in the ratio of P-AKT and AKT, which were 5.8702±0.0543, 5.0755±0.0888, 3.8353±0.0056. The ratios of P-AKT and AKT had association with histological type, the ratios in squamous cancer of the cervix and in adenocancer and denosquamous cancer were 6.7823±0.7745 and 0.7621±0.0709, and the ratios were much higher in squamous cancer of the cervix than adenocancer and denosquamous cancer. Conclusions Overexpression of PI3K protein is involved in the occurrence of human cervical cancer. The ratio of P-AKT and AKT plays a more important role in squamous cancer of the cervix.
