Objective To investigate the clinical effects of Shenlian capsule,trastuzumab combined with SOX regimen in the treatment for HER-2 positive advanced gastric carcinoma.Methods A total of 314 patients with HER-2 positive advanced gastric carcinoma in our hospital were randomly divided observation group and control group,157 cases in each group.The observation group was treated by SOX regimen and trastuzumab,while the control group was given Shenlian capsule on the base of control group.After treatment,the short-term effects in the 2 groups were evaluated.Before and after the treatment,the levels of SDF-1,CXCR4,FSP-1 and MRP-l4 in the 2 groups were detected.During the treatment,the rates of neurotoxicity,gastrointestinal reaction,liver function injury,renal function injury,rashes and bone marrow suppression were observed in the 2 groups.After the treatment,3 years follow-up was performed,the 1 year survival rate,3 year survival rate,overall survival (OS) and progression-free survival (PFS) were observed.Results After the treatment,the control rate (92.7％ vs.79.9％;Z=3.812,P=0.037) and efficiency rate (78.1％ vs.66.4％;Z=3.712,P=0.039) were significantly higher in treatment group than which in the control group (P＜0.05).After the treatment,the levels of SDF-1,CXCR4,FSP-1,MRP-14 in treatment group were significantly lower than control group (t=4.091,4.310,3.972,3.821,P＜0.05).During the treatment,the rates of neurotoxicity,gastrointestinal reaction,liver function injury,renal function injury,rashes,bone marrow suppression were significantly lower in treatment group than control group (x2=5.182,4.671,4.491,5.091,5.204,4.925,P＜0.05 or P＜0.01).After the treatment,the PFS,OS (t=3.714,3.612,P＜0.05),3 year survival rate (x2=3.105,P=0.043) were significantly higher in treatment group than the control group.Conclusions The Shenlian capsule,trastuzumab combined with SOX regimen has a good effect and low toxic effects in the treatment of HER-2 positive advanced gastric carcinoma,and they could prolong the survival time.

Objective To investigate the CT and MRI manifestations of intra-abdominal aggressive fibromatosis and correlation with pathology.Methods The CT and MRI manifestations of 26 cases with intra-abdominal aggressive fibromatosis confirmed by pathological examination were analyzed retrospectively.Results 26 cases showed single solid mass,13 cases showed well-circumscribed and round-like,9 cases wrapped around the common bile duct,intestine or ureter,4 cases were lobulated which had unclear margin with surrounding tissues in pelvic.All the lesions displayed isodensity or slightly low density non-enhanced CT appearance,heterogenous high intensity FS T2WI,some larger tumors showed mixed signal.CT/MRI enhanced scan showed gradual enhancement in 26 cases.Conclusion Intra-abdominal aggressive fibromatosis have some certain imaging features,MRI can offer the histo logical features of tumors and have some correlation with pathology.

This paper summarized the characteristics, rehabilitation needs, and situation and problems of stroke dysfunction in China. Approaches and methods of family rehabilitation were also discussed.

One of the distinct characters of Latrodectus tredecimguttatus is that its toxic components exist not only in the venomous glands, but also in the tissues outside the venomous glands and even in the eggs. Investigation on the toxins outside the venomous glands can deepen our understanding of spider toxins and discover new lead molecules with important application prospects. In order to explore the low-abundance proteinaceous toxins in the L. tredecimguttatus eggs, we used bioinformatic strategies to mine a gene sequence encoding a peptide toxin from the transcriptome of L. tredecimguttatus eggs, and then heterologously expressed the gene successfully with a 3'-RACE combined with nest PCR strategy. Biological activity analyses indicated that the expressed peptide toxin, named latroeggtoxin-Ⅵ (LETX-Ⅵ), could inhibit Na⁺ channel currents in ND7/23 cells and promote dopamine release from PC12 cells, without obvious toxicity against Periplaneta americana and bacteria as well as fungi including Staphylococcus aureus and Candida albicans, demonstrating that LETX-Ⅵ is a mammal-specific neurotoxin with a potential application prospect in development of the tool reagents for neurobiological study and the drugs for treating related diseases.
