Objective To study the clinicopathological features and prognosis of Gastric hepatoid adenocarcinoma (GHA) and aims to guide future clinical practice.Method We retrospectively studied the clinical data of 25 patients with pathologically confirmed GHA who were admitted to our hospital from January 2003 to December 2015.Results There were 19 males and 6 females.The average age was 61.2 years.The clinical manifestations were non-specific.Pathologically,majority of GHA presented with ulcerative type,poor differentiation and extensive vascular cancerous embolus.Preoperative liver metastases were found in 12 patients,and postoperative liver metastases in 15 patients.Conclusions GHA is a special primary gastric adenocarcinoma which possesses both hepatocellular carcinoma-like and adenocarcinoma-like histology.GHA is characterized by a significantly elevated serum AFP and early hepatic metastasis.GHA is therefore often misdiagnosed as primary hepatocellular carcinoma.The main treatment option remains to be surgical resection,and the prognosis is poor.

OBJECTlVE To study the effect of eucaIyptus oiI on fetus skeIetaI deveIopment of retin-oic acid( RA)induced teratogenic rats. METHODS Forty-two pregnant SD rats were randomIy and equaIIy divided into 6 groups:eucaIyptus oiI 100,200 and 300 mg·kg-1+RA groups,soIvent group(peanut oiI+RA)group,RA group and normaI group with normaI diet. Three eucaIyptus oiI and soIvent groups were ig given eucaIyptus oiI in 100,200,and 300 mg·kg-1 and peanut oiI 2 mL at the 7th to 14th day of gestation,respectiveIy,and RA 40 mg·kg-1 at the 10th day of gestation. RA group were ig given RA 40 mg·kg-1 at the 10th day of gestation. AII pregnant rats were sacrificed at the 21th day. The Iength of fetus body and taiI as weII as body mass of the embryos were measured. 1/ 2-1/ 3 fetaI rats from each Iitter were randomIy extracted to observe skeIetaI deveIopment under a stereoscope by staining with aIcian bIue and aIizarin red S. The Iength of Iimbs and bone ossification was measured. RESULTS The fetus body mass,body Iength,taiI Iength of normaI group significantIy surpassed those in the other groups(P﹤0.05,P﹤0.01). The fetus body mass and body Iength of each eucaIyptus oiI group were significantIy better than RA group(P﹤0.05,P﹤0.01). The fetus body mass,body Iength and taiI Iength of soIvent group were not significantIy different from those in the RA group. The fetus taiI Iength in eucaIyptus oiI groups had no significant difference compared with RA group. The Iimb and bone ossification of normaI group were Ionger than in RA group(P﹤0.05,P﹤0.01). The Iimb Iength of the eucaIyptus oiI groups was Ionger than in RA group and soIvent controI group(P﹤0.05,P﹤0.01),but there was no difference between the soIvent controI group and RA group. The Iimb ossification of each eucaIyptus oiI group was aIso Ionger than that in RA group and soIvent controI group(P﹤0.05,P﹤0.01),but there was no difference between the soIvent controI group and RA group. CONCLUSlON EucaIyptus oiI can antagonize the retardation of skeIetaI growth and ossification of fetaI rats caused by RA.

The p21 activated kinase 4 (PAK4) is serine/threonine protein kinase that is critical for cancer progression. Guided by X-ray crystallography and structure-based optimization, we report a novel subseries of C-3-substituted 6-ethynyl-1H-indole derivatives that display high potential and specificity towards group II PAKs. Among these inhibitors, compound 55 exhibited excellent inhibitory activity and kinase selectivity, displayed superior anti-migratory and anti-invasive properties against the lung cancer cell line A549 and the melanoma cell line B16. Compound 55 exhibited potent in vivo antitumor metastatic efficacy, with over 80% and 90% inhibition of lung metastasis in A549 or B16-BL6 lung metastasis models, respectively. Further mechanistic studies demonstrated that compound 55 mitigated TGF-β1-induced epithelial-mesenchymal transition (EMT).
