RESUMEN
OBJECTIVE: Non-cirrhotic porto-mesenteric vein thrombosis (NC-PMVT) is a rare but severe clinical condition. The study aims to assess the effectiveness and safety of transjugular intrahepatic portosystemic shunt (TIPS) coupled with dual-access thrombolysis in patients with acute severe NC-PMVT. METHODS: From January 2018 to February 2023, a total of 25 patients with acute severe NC-PMVT who were treated with TIPS in conjunction with mechanical thrombectomy and dual-access thrombolysis. The period of thrombolysis was determined by the improvement of clinical symptoms and vascular recanalization. The technical success, recanalization rate, clinical success, and procedure-related complications were analyzed. RESULTS: The technical success rate was 100 %. The median duration for thrombolytic catheter removal was 5 (IQR 3.5 - 7) days. Full and partial recanalization were accomplished in 10 (40 %) and 15 (60 %) patients respectively before discharge. No significant procedure-related complications were reported. The clinical success rate was 88 %, with a mortality rate of 12 %. Over a median follow-up of 8 months, 3/22 (13.64 %) patients had a recurrence of thrombosis; 1/22 (4.54 %) patients underwent partial intestinal resection one and a half months post-discharge; the remaining patients did not experience any portal hypertensive complications. CONCLUSION: The combination of TIPS and dual-access thrombolysis appears to be safe and effective for patients with acute severe NC-PMVT.
RESUMEN
The miR2118 is highly conserved in leguminous plants. Its function is to regulate the expression of genes encoding the TIR-NBS-LRR resistance protein. In this study, cin-miR2118 from Caragana intermedia was functionally characterized, especially with regard to its role in drought stress resistance. Two target genes of cin-miR2118 were predicted and cloned, the occurrence of miR2118 target sequence in both genes indicated that they might be targets of cin-miR2118. We investigated the expression patterns of cin-miR2118 and its target genes in C. intermedia stems and found diverse changes in expression in response to drought stress. CiDR1 was negatively correlated with corresponding miR2118 expression while CiDR2 was positively correlated with cin-miR2118. For further study, induced tolerance was observed in the transgenic Tobacco with overexpression cin-miR2118 upon 140-min water deficiency. And the expression level of cin-miR2118 was dramatically increased under drought stress. These results reveal that cin-miR2118 exert positive effects on drought stress tolerance. In addition, our study unexpectedly found that overexpression of cin-miR2118 in Tobacco can cause phenotype changes, which suggested that cin-miR2118 may have a novel function as a growth regulator in Tobacco.
