Topic: Analyzing the Impact of Social Media Use on Anxiety and Depression in Health Crises: A Comparative Study of Chinese and International Students in China During COVID-19
Abstract: The purpose of this study was to ascertain whether there exist differences in the impact of social media use on anxiety and depression among Chinese and International students in China during the peak of COVID-19. A structured online questionnaire was distributed among Chinese and International students across China, based on modified instruments from the generalized anxiety disorder 7 (GAD-7), the Patient Health Questionnaire 9 (PHQ-9), and social media use. Three hundred and ten (310) responses from Chinese students and 474 from International students were further analyzed using the Partial Least Squares based on structural equation Modelling (PLS-PM). This study found a significant negative relationship between social media use and anxiety (β= -0.382, p<.001) and social media use and depression (β= -0.134, p< .001) among Chinese students. Similarly, a significant negative relationship was observed between social media use and anxiety (β= -0.381, p<.001) and social media use and depression (β=-0.390, p< .001) among International students. This suggests that social media use did not cause increased anxiety and depression of Chinese and International students during COVID-19. No significant difference was also found between the impact of social media use on anxiety and depression among the two categories of students. This study provides valuable insights into understanding the impact of social media use on anxiety and depression among students during the peak of COVID-19. Based on the findings of this study, stakeholders must continue to roll out online initiatives, such as mental health programs, online counselling and circulation of relevant COVID-19 related information on universities' websites, microblogs and other social media websites. These programs could help mitigate the harmful effects of social media among students in COVID-19.

Topic: Metabolic Culprits in Obese Pregnancies: Big Moms, Big Babies, and Big Picture
Abstract: Obesity has become a major health issue in recent decades, and has been documented to exert unfavourable effects on humans and animals and potentially affect the health of their offspring. However, the long-term effects of maternal obesity during the perinatal period on metabolic systems of the offspring have not been determined. Our group has long been focus on to explore epigenetic mechanisms underlying the inter- or trans-generational influence of maternal obesity/diabetes and identify critical molecules which are associated with metabolic programming under conditions of intrauterine and or postnatal obesogenic conditions. Here, we investigate metabolic effect of early activated hypothalamic endoplasmic reticulum (ER) stress in offspring exposed to maternal obesogenic environment and the potential mechanism underlying the metabolic abnormalities. Our study demonstrated that the uncoordinated interaction between the unfolded protein response and the heat shock response might be responsible for the malformed hypothalamic feeding circuit of the offspring exposure to maternal obesogenic conditions and were linked with deleterious metabolism in adulthood, especially when exposure to high-energy conditions.

Topic: Stress-Induced Phosphoprotein 1 Restrains Spinal Cord Ischemia-Reperfusion Injury by Regulating Nf-Κb Signaling
Abstract: This study aims to investigate the effects of stress-induced phosphoprotein 1 (STIP1) on spinal cord ischemia-reperfusion injury (SCII). SCII was induced by clamping the abdominal aorta for 1 h and reperfusion for 24 h in rats. Immunoblotting and immunohistochemical staining results showed that STIP1 rapidly increased and then decreased in the spinal cord of rats with SCII treatment. Lentivirus containing STIP1 coding sequence was intrathecally injected into rats to overexpress STIP1. Neurological function score, HE staining, immunofluorescent staining, and western blot results revealed that STIP1 overexpression alleviated SCII-induced motor dysfunction of hind limbs, neuronal loss and inflammation in the spinal cord, and inhibited activity of nuclear factor kappa B (NF-κB) signaling in rats. Moreover, STIP1 co-located with Iba-1, a marker of activated microglia. Mouse microglia BV2 underwent oxygen and glucose deprivation (OGD) for 6 h, and reperfusion for 24 h. STIP1 ameliorated OGD-induced inflammation and activation of NF-κB signaling in BV2 cells. In addition, STIP1 resulted in the decrease of heat shock protein family A member 8 (HSPA8), an increase of inhibitor of NF-κB (IκB)β levels, and IκBβ bound to HSPA8 in BV2 cells. We hypothesized that STIP1 elevated IκBβ levels by occupying HSPA8, and then deactivated NF-κB signaling. In summary, STIP1 alleviated ischemia-reperfusion induced neuronal injury and inflammation in the spinal cord of rats and mouse microglial cells by deactivating NF-κB signaling. These findings may provide novel insights for clinical diagnosis and treatment for spinal cord injury.

Topic: Key Molecular Alterations in Endothelial Cells in Human Glioblastoma Uncovered by Single-Cell RNA Sequencing
Abstract: Glioblastoma is the most aggressive type of brain tumor with poor therapeutic response and prognosis. Passage of systemically delivered pharmacological agents into the brain is largely blocked by the blood-brain-barrier (BBB), an organotypic specialization of brain endothelial cells (ECs). Tumor vessels in GBM are abnormal and generally more permeable, but the heterogeneity of BBB breakdown in different parts of the tumor vascular tree and in vessels surrounding the tumor is largely unknown. Here, through single-cell RNA sequencing (sc-RNAseq) of freshly isolated ECs from human glioblastoma and paired non-malignant tissues, we have constructed a molecular atlas of human brain ECs providing unprecedented molecular insight into the heterogeneity of the human BBB and its molecular alteration in glioblastoma. We identified 5 distinct EC phenotypes, resembling different phenotypes and associating with distinct anatomical location within the tumor. This unique resource will provide key information for designing rational therapeutic regimens and optimizing drug delivery.
