Objective:To explore the prognostic factors of patients with Vibrio vulnificus sepsis. Methods:The clinical data of 67 patients with Vibrio vulnificus sepsis from January 2008 to December 2019 in the First Affiliated Hospital of Wenzhou Medical University were retrospectively analyzed. Univariate analysis was used to compare the differences in general information, clinical manifestations, admission laboratory indicators, antibiotics and surgery between the death group and the cured group. Then the factors with significant difference in univariate analysis were included in multivariate analysis, and the factors of prognosis were obtained. Results:Univariate analysis showed that there were significant difference in liver disease, admission with hypotension shock, multiple limb injuries; admission leukocytes, platelets, pH value, albumin, lactic acid, aspartate aminotransferase, creatinine, procalcitonin, creatine kinase, activated partial thromboplastin time, prothrombin time between the death group and the cured group (all P <0.05). Multivariate analysis showed that admission lactate ( OR=0.628, 95% CI: 0.461-0.855, P=0.003), albumin ( OR=1.330, 95% CI:1.062-1.667, P=0.013), creatine kinase ( OR=0.999, 95% CI: 0.998-1.000, P=0.016) and admission surgery time ( OR=0.118, 95% CI: 0.015-0.938, P=0.043) were risk factors of the prognosis. Patients with high lactate, creatine kinase and low albumin at admission indicate poor prognosis; patients with admission surgery time≤ 12 h have better prognosis. Conclusion:For the treatment of patients with Vibrio vulnificus sepsis, medical staff should dynamically evaluate these prognostic factors in the early stage, and early surgical treatment should be adopted to improve the prognosis of patients.

Objective:To investigate the diagnostic value of endoscopic ultrasonography (EUS) in pancreatic duct stones.Methods:The clinicopathologic data of 204 patients undergoing EUS for symptoms such as abdominal pain, abdominal distension and jaundice suspected of pancreatic duct stones, who were admitted to the General Hospital of Western Theater Command from January 2019 to April 2023 were retrospectively analyzed. Of 159 patients were finally enrolled, including 47 females and 112 males, aged (51.8±13.9) years. Surgery or endoscopic retrograde cholangiopancreatography (ERCP) is considered the " gold standard" for the diagnosis of pancreatic duct stones. Of 38 patients (23.9%) had abdominal ultrasound, 143 (89.9%) had CT scan and 93 (58.5%) had magnetic resonance cholangiopancreatography (MRCP) at the same time. The diagnostic accuracy of imaging examinations in pancreatic duct stones was compared.Results:In 159 patients, 61 (38.4%) were diagnosed of pancreatic duct stones. In the 159 patients, 61 (38.4%) were diagnosed of pancreatic duct stones by EUS. The diagnostic sensitivity, specificity, positive predictive value, negative predictive value, Youden index and accuracy of EUS for pancreatic duct stones were 98.4%, 99.0%, 98.4%, 99.0%, 97.3% and 98.7%, respectively. The accuracy of EUS in diagnosing pancreatic duct stones was higher than that of percutaneous ultrasound, CT and MRCP (χ 2=7.71, 13.76, and 5.70, P=0.012, <0.001, 0.033). The diagnostic accuracy of EUS is comparable with operation and ERCP (Kappa=0.854, P<0.001). Conclusion:EUS could be a superior imaging approach to diagnose the pancreatic duct stone.

The dynamic activity of transposable elements (TEs) contributes to the vast diversity of genome size and architecture among plants. Here, we examined the genomic distribution and transposition activity of long terminal repeat retrotransposons (LTR-RTs) in Arabidopsis thaliana (Ath) and three of its relatives, Arabidopsis lyrata (Aly), Eutrema salsugineum (Esa), and Schrenkiella parvula (Spa), in Brassicaceae. Our analyses revealed the distinct evolutionary dynamics of Gypsyretrotransposons, which reflects the different patterns of genome size changes of the four species over the past million years. The rate of Gypsy transposition in Aly is approximately five times more rapid than that of Ath and Esa, suggesting an expanding Aly genome. Gypsy insertions in Esa are strictly confined to pericentromeric heterochromatin and associated with dramatic centromere expansion. In contrast, Gypsy insertions in Spa have been largely suppressed over the last million years, likely as a result of a combination of an inherent molecular mechanism of preferential DNA removal and purifying selection at Gypsy elements. Additionally, species-specific clades of Gypsy elements shaped the distinct genome architectures of Aly and Esa.

Soluble epoxide hydrolase (sEH) is related to arachidonic acid cascade and is over-expressed in a variety of diseases, making sEH an attractive target for the treatment of pain as well as inflammatory-related diseases. A new series of memantyl urea derivatives as potent sEH inhibitors was obtained using our previous reported compound 4 as lead compound. A preferential modification of piperidinyl to 3-carbamoyl piperidinyl was identified for this series via structure-based rational drug design. Compound A20 exhibited moderate percentage plasma protein binding (88.6%) and better metabolic stability in vitro. After oral administration, the bioavailability of A20 was 28.6%. Acute toxicity test showed that A20 was well tolerated and there was no adverse event encountered at dose of 6.0 g/kg. Inhibitor A20 also displayed robust analgesic effect in vivo and dose-dependently attenuated neuropathic pain in rat model induced by spared nerve injury, which was better than gabapentin and sEH inhibitor (±)-EC-5026. In one word, the oral administration of A20 significantly alleviated pain and improved the health status of the rats, demonstrating that A20 was a promising candidate to be further evaluated for the treatment of neuropathic pain.
