Objective To observe the pulmonary inflammation and oxidative stress in rats with cecal ligation and puncture sepsis. Methods The male rats in 8 weeks were randomly divided into control group, sham operation group and model group,The ALI model of sepsis was prepared by cecal ligation and puncture (CLP). In order to achieve the effect of experimental observation, the rats were killed after the operation 12 h, and the lung tissue HE staining analysis was performed, and the levels of MPO and MDA were observed. Results The degree of lung injury and the levels of MPO and MDA in the model group were significantly higher than those in the control group and the sham operation group (P < 0.01).Conclusion Rats with cecal ligation and puncture sepsis model can well simulate sepsis inflammatory response and oxidative stress.

OBJECTIVETo study the constituents of Evodia rutaecarpa.
METHODThe constituents were isolated by various chromatographic techniques and the structures were elucidated by their physicochemical properties and the spectral data analysis.
RESULTEleven compounds were isolated and identified as rutaecarpine (1), dehydroevodiamine (2), limonin (3), wuchuyuamide I (4), evocarpine (5), daucosterol (6), taraxerone (7), 14-ursen-3-ol-1-one (8), trans-caffeic acid methylate (9), methyl coumarate (10), caffeine (11).
CONCLUSIONCompounds 7, 8, 10, 11 were isolated from E. rutaecarpa for the first time.

Increasing prevalence of childhood obesity poses threats to the global health burden. Because this rising prevalence cannot be fully explained by traditional risk factors such as unhealthy diet and physical inactivity, early-life exposure to endocrine disrupting chemicals (EDCs) is recognized as emerging novel risk factors for childhood obesity. EDCs can disrupt the hormone-mediated metabolic pathways, affect children’s growth and mediate the development of childhood obesity. Many organic pollutants are recently classified to be EDCs. In this review, we summarized the epidemiological and laboratory evidence related to EDCs and childhood obesity, and discussed the possible mechanisms underpinning childhood obesity and early-life exposure to non-persistent organic pollutants (phthalates, bisphenol A, triclosan) and persistent organic pollutants (dichlorodiphenyltrichloroethane, polychlorinated biphenyls, polybrominated diphenyl ethers, per- and polyfluoroalkyl substances). Understanding the relationship between EDCs and childhood obesity helps to raise public awareness and formulate public health policy to protect the youth from exposure to the harmful effects of EDCs.

Purpose:
Whether a dilated intrahepatic bile duct (IHBD) has any effect on the prognosis of choledochal cyst (CC) remains controversial. We aimed to summarize the clinical characteristics and prognosis of CC with IHBD dilatation.
Methods:
One hundred ninety-two children diagnosed with CC were identified, including 127 without IHBD dilatation (group A) and 65 with IHBD dilatation (group B). A retrospective analysis was performed to explore the clinical characteristics and prognosis of CC with IHBD dilatation based on clinical indices, symptoms, and complications.
Results:
Compared with group A, incidences of jaundice and fever were higher in group B (P = 0.010 and P = 0.033). Preoperative total bilirubin, direct bilirubin, and indirect bilirubin were increased in group B compared to group A (P = 0.005, P < 0.001, and P = 0.014), as were preoperative ALT, AST, γ-GT, and total bile acid (P = 0.006, P = 0.025, P < 0.001, and P = 0.024). The risk of liver fibrosis or cirrhosis was significantly increased for group B compared with group A (P = 0.012) and also occurred earlier in group B (P = 0.006). In the dilated IHBDs, 95.4% (62 of 65) recovered to normal, and more than half of dilated IHBDs (37 of 65) recovered to normal in 1 week.
Conclusion
Most IHBDs can recover to normal postoperatively in a short time, and proactive treatment is recommended for CC patients with IHBD dilatation for significant abnormal liver functions.
