RESUMO
@#Abstract: Superior mesenteric veinous thrombosis (SMVT) is a rare complication that often occurs in conjunction with intra-abdominal diseases such as diverticulitis, appendicitis, inflammatory bowel disease, etc. Its clinical symptoms are non-specific and include fevers, abdominal pain; it has no specific symptoms, and the diagnosis depends on clinical laboratory tests and imaging studies. The occurrence of superior mesenteric veinous thrombophlebitis is related to septic phlebitis caused by the sloughing of the embolus containing bacteria into the portal vein with blood flow. Due to the nonspecific clinical features of this disease, diagnosing it based on clinical characteristics and microbiological aspects is a challenge. A case of superior mesenteric veinous septic thrombophlebitis caused by Bacteroides fragilis infection is reported and to provide a reference for the diagnosis and treatment of such diseases. The patient was a 34-year-old man who was admitted the hospital with intermittent abdominal pain and fever. Computed tomography (CT) showed partial thrombosis of the superior mesenteric vein, colonoscopy revealed diverticulitis in the ileoceca, and the blood culture grew Bacteroides fragilis. The patient was treated with anti-infection (ceftazidime 2.0 g q12h intravenous infusion for 11 days; metronidazole 0.5 g, q8h intravenous infusion for 3 days) and anticoagulation (rivaroxaban 20 mg qd orally for 8 days. On the 11th day of hospitalization, the patient's condition improved, and he was discharged. In this case, for patients with fever and abdominal pain, superior mesenteric venous thrombophlebitis should be included in the differential diagnosis. Through auxiliary examination, blood sample culture and other technologies, clear diagnosis should be made in time to improve patient outcomes.
RESUMO
BACKGROUND: The aim of this study was to explore epilepsy-related mechanism so as to figure out the possible targets for epilepsy treatment. METHODS: The gene expression profile dataset GES32534 was downloaded from Gene Expression Omnibus database. We identified the differentially expressed genes (DEGs) by Affy package. Then the DEGs were used to perform gene ontology (GO) and pathway enrichment analyses. Furthermore, a protein-protein interaction (PPI) network was constructed with the DEGs followed by co-expression modules construction and analysis. RESULTS: Total 420 DEGs were screened out, including 214 up-regulated and 206 down-regulated genes. Functional enrichment analysis revealed that down-regulated genes were mainly involved in the process of immunity regulation and biological repairing process while up-regulated genes were closely related to transporter activity. PPI network analysis showed the top ten genes with high degrees were all down-regulated, among which FN1 had the highest degree. The up-regulated and down-regulated DEGs in the PPI network generated two obvious sub-co-expression modules, respectively. In up-co-expression module, SCN3B (sodium channel, voltage gated, type III beta subunit) was enriched in GO:0006814 ~ sodium ion transport. In down-co-expression module, C1QB (complement C1s), CIS (complement component 1, S subcomponent) and CFI (complement factor I) were enriched in GO:0006955 ~ immune response. CONCLUSION: The immune response and complement system play a major role in the pathogenesis of epilepsy. Additionally, C1QB, C1S, CFI, SCN3B and FN1 may be potential therapeutic targets for epilepsy.
