RESUMO
Objective To investigate the clinical features, laboratory findings, chest CT findings and treatment of patients with COVID-19, and to analyze their relationship with prognosis. Methods From January to February 2020, the clinical data on the 42 patients with COVID-19 admitted to the Wenzhou Sixth People′s Hospital were analyzed retrospectively. Results The clinical symptoms of the 42 cases included fever (35 cases), cough (26 cases), fatigue (14 cases), aspiration (9 cases), sore throat (4 cases), muscle ache (5 cases), headache (2 cases), nausea (4 cases), diarrhea (6 cases) and abdominal pain (1 case).The absolute number of blood lymphocyte decreased to different degrees in 22 cases.Fourteen cases had lactate dehydrogenase obviously, with no obvious change in procalcitonin.The imaging manifestations were cloud-like and ground-glass-like high density shadows scattered outside the lungs, small flaky consolidation and bronchus inflating sign were seen locally.A few images showed diffuse high density, most of the lesions showed consolidation or striate change, and local fibrosis was formed in the lower lobes of both lungs. Conclusion Fever and cough are the first symptoms of COVID-19, and a few cases are associated with shortness of breath and diarrhea, accompanied by different degrees of systemic symptoms, but most of the patients improve their conditions after active antivirus, anti-infection, systematic symptoms improvement and supportive treatment.The disease is highly infectious and its condition changes rapidly.Therefore, early detection, early diagnosis and comprehensive treatment of the whole body as soon as possible are the keys to treatment.
RESUMO
Animals integrate various environmental stimuli within the nervous system to generate proper behavioral responses. However, the underlying neural circuits and molecular mechanisms are largely unknown. The insulin-like signaling pathway is known to regulate dauer formation, fat metabolism, and longevity in Caenorhabditis elegans (C. Elegans). Here, we show that this highly conserved signaling pathway also functions in the integrative response to an olfactory diacetyl and a gustatory Cu(2+) stimuli. Worms of wild-type N2 Bristol displayed a strong avoidance to the Cu(2+) barrier in the migration pathway to the attractive diacetyl. Mutants of daf-2 (insulin receptor), daf-18 (PTEN lipid phosphatase), pdk-1 (phosphoinositide-dependent kinase), akt-1/-2 (Akt/PKB kinase) and sgk-1 (serum- and glucocorticoid-inducible kinase) show severe defects in the elusion from the Cu(2+). Mutations in DAF-16, a forkhead-type transcriptional factor, suppress the integrative defects of daf-2 and akt-1/-2 mutants. We further report that neither cGMP nor TGFβ pathways, two other dauer formation regulators, likely plays a role in the integrative learning. These results suggest that the insulin-like signaling pathway constitutes an essential component for sensory integration and decision-making behavior plasticity.
