RESUMEN
ObjectiveTo investigate the effect and mechanism of echinacoside （ECH） in improving liver injury in rats with acute pancreatitis by establishing a rat model of acute pancreatitis and liver injury. MethodsA total of 24 Sprague-Dawley rats were randomly divided into blank group （Con group）， control group （Con+ECH group）， acute pancreatitis group （AP group）， and acute pancreatitis+ECH intervention （AP+ECH group）. The rats were given intraperitoneal injection of 10 mg/kg ECH on day 7 before the establishment of the model of acute pancreatitis； at 24 hours after the last administration of cerulein， blood samples were collected via the abdominal aorta， and serum was separated for biochemical analysis including alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， lactate dehydrogenase （LDH）， gamma-glutamyl transpeptidase （GGT）， alkaline phosphatase （ALP）， albumin （Alb）， total bilirubin （TBil）， cholinesterase， blood amylase （Amy）， and lipase （LPS）. HE staining was used to observe the histopathological changes of the pancreas and the liver； transmission electron microscopy （TEM） was used to observe the microstructural changes of pancreas and liver tissue； ELISA was used to measure the levels of interleukin-1β （IL-1β）， interleukin-16 （IL-6）， tumor necrosis factor-α （TNF-α）， and interleukin-10 （IL-10） in liver tissue homogenate； immunohistochemistry was used to measure the levels of TNF-α and p-p65 NF-κB in pancreas and liver tissue； Western blot was used to measure the expression levels of NF-κB pathway proteins in liver tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the SNK test or the Dunnett’s T3 method was used for further comparison between two groups. ResultsCompared with the Con group， the AP group had significant increases in ALT， AST， GGT， LDH， ALP， TBil， Amy， and LPS （all P<0.01）， as well as significant increases in the levels of IL-1β， IL-6， IL-10， and TNF-α in liver tissue homogenate （all P<0.01）. ECH intervention reduced the levels of ALT， AST， GGT， LDH， ALP， TBil， AMY， and LPS and inhibited the secretion of IL-1β， IL-6， and TNF-α in rats with acute pancreatitis. HE staining showed that ECH intervention alleviated the vacuolar degeneration of acinar cells， inflammatory cell infiltration in pancreatic tissue， and the necrosis of hepatocytes compared with the AP group. TEM showed that compared with the AP group， there was a reduction in the degree of mitochondrial swelling in liver and pancreatic cells after ECH intervention. ECH intervention partially reversed the elevated expression levels of p-p65 NF-κB and TNF-α in liver and pancreatic tissue. In addition， the expression levels of MyD88， p-IκBα， p-IKKα， and p-p65 were upregulated in liver tissue of rats with acute pancreatitis， which could be partially reversed after ECH intervention. ConclusionEchinacoside can alleviate liver and pancreatic injury induced by acute pancreatitis by inhibiting the TLR4/MyD88/NF-κB pathway.
RESUMEN
Echinococcosis is a zoonotic parasitic disease caused by infection with Echinococcus species. As the drug of first choice for treatment of echinococcosis, albendazole suffers from problems of large doses and remarkable adverse reactions in clinical therapy. Development of novel drugs against echinococcosis is of urgent need. Recently, great advances have been achieved in the research on traditional Chinese medicine for treatment of echinococcosis. This review summarizes the progress of researches on traditional Chinese medicine for treatment of echinococcosis, aiming to provide insights into development of anti-echinococcosis drugs.
RESUMEN
Alveolar echinococcosis (AE) is considered as a fatal zoonosis caused by the larvae of Echinococcus multilocularis. The lungs and brain are the most common metastatic organs. We report a human case of hepatic alveolar echinococcosis accompanied by lung and brain metastasis. In particular, the patient had a history of tuberculosis and the lung lesions were easily misdiagnosed as lung abscesses. The lesions of liver and lung underwent radical resection and confirmed as alveolar echinococcosis by pathological examination. The patient had no surgical complications after operation and was discharged after symptomatic treatment. Unfortunately, the patient later developed multiple intracerebral AE metastases. We required the patient to take albendazole orally for life and follow up.

RESUMEN
[ABSTRACT]OBJECTIVETo investigate the relationship between upper airway MRI parameters and the severity of patients with obstructive sleep apnea hypopnea syndrome (OSAHS). Then the values of upper airway MRI parameters in waking state were assessed.METHODS The MRI upper airway parameters of 37 OSAHS patients and 18 nonsnoring normal subjects were measured and compared. Then data analysis were carried out to find out significant correlations between the MRI upper airway parameters and the severity of patients (the apnea hypopnea index, AHI; the lowest oxygen saturation, LSaO2; the oxygen desaturation index, ODI) with OSAHS.RESULTSThe correlation between cross-sectional areas and left-right diameter in the narrowest retropalatal region, the thickness of lateral pharyngeal wall, the length of the tongue, the length and thickness of the soft palate and the cross-sectional areas of the soft palate on midsagittal planes and severity of OSAHS were found (P<0.05).CONCLUSIONThe MRI upper airway parameters can be used in evaluating the severity of OSAHS in some ways, locating the obstruction sites and choosing the best treatment planning.
