Glypican-3 ( GPC3 ) plays very important role in the regulation of cell growth and differentiation in hepatocellular car-cinoma ( HCC ) . GPC3 is closely related to the occurrence and development of HCC. A dramatic elevation of GPC3 expression has been reported in a large proportion of HCC, which suggests that GPC3 is remarkably sensitive and specific to the diagnosis of HCC. GPC3 is a potential therapeutic target of HCC. This paper reviews the structure and function of GPC3, the progress of im-munotherapy based on GPC3 of HCC, and discusses the prospect of therapeutic target of liver cancer in the future.

Aim To investigate the apoptosis of human gastric carcinoma AGS cells induced by cecropinXJ. Methods Human gastric carcinoma AGS cells and human normal epithelial cells GES-1 were co-cultured with different concentrations of cecropinXJ ranging from 0. 01 to 1 000 mg·L-1 for 24 h. MTT assay was used to observe the effects of cecropinXJ on the proliferation of AGS cells and GES-1 cells. The ultrastructural changes of the AGS cells were observed by transmission electron microscopy. Hoechst staining was used to de-tect cell apoptosis. The changes of intracellular reac-tive oxygen species ( ROS) and mitochondrial potential were analysed by flow cytometery. The expression of Bax, Bcl-2, caspase-3 and cytochrome C in mRNA level was investigated by qRT-PCR. Western blot was used to determine the protein expression of Bax, Bcl-2, caspase-3 and cytochrome C. Results CecropinXJ significantly suppressed the proliferation of AGS cells in vitro (P<0. 05) in a dose-dependent manner, IC50 =61. 19 mg·L-1 , but had no inhibitive effects on the proliferation of GES-1 cells. After treatment for 24 h, cecropinXJ induced AGS cells nuclear condensation, and increased ROS production, disrupted mitochondri-al integrity. The results of qRT-PCR and Western blot demonstrated cecropinXJ could up-regulate the expres-sion of Bax and down-regulate the expression of Bcl-2 , promote the release of cytochrome C and activate caspase-3. Meanwhile, cecropinXJ promoted caspase-3 activity in a dose-dependent manner, and cell death ratio of AGS cells induced by cecropinXJ was signifi-cantly reduced by caspase-3 and caspase-9 specific in-hibitors treatment. Conclusion CecropinXJ can in-duce apoptosis of AGS cells by downregulating Bcl-2 , upregulating Bax and activating caspase-3 , which may be one of its anti-tumor mechanisms.

Objective:Antimicrobial peptides ( AMPs ) are peptides generated in the biological defense system against exogenous pathogens ,which is all important constituent of the non-specific immune system.The immune system can react and sometimes play an important role in tumor control both in animal models and in humans.In this study,CecropinXJ were used in the BALB/c Eca109 cells-bearing mice model.To investigate whether CecropinXJ exert anti-tumor efficiency through regulating immune response when treated with tumor-bearing mice.Methods:The expression of cytokines and DC surface molecules were detected by immunohisto-chemistry and Flow cytometry.Results:The experiment of mice showed that CecropinXJ could significantly inhibit the proliferation of transplanted tumors in dose-dependent manner.There were significant difference between control group and 10mg/kg CecropinXJ group on the volume and weight of tumor ( P<0.05 ).CecropinXJ inhibited Eca 109 cells infiltrating growth in tumor tissue without affecting viscera,and the expressions of VEGF and bFGF proteins were higher than those in the control group .The expression of cytokines and DC surface molecules,the results that,compared with the control group,CecropinXJ could not significantly promote the expression of CD4,IL-4 and IFN-γ,while not involving the expression of surface molecules on DCs in spleen (P>0.05).In CecropinXJ treatment group,TNF-αlevel in serum was significantly higher than the control group ( P<0.01 ).Conclusion: CecropinXJ could significantly inhibit tumor growth in Eca109 cells-bearing mice,and might not be affected anti-tumor efficiency through regulating immune response.

Objective To find out the brain function characters of visual information integration and visual working memory with attention deficit hyperactivity disorder (ADHD) children. Methods 1∶ 1 case-control study was used on the study. 45 ADHD children who met DSM-IV criteria were recruited as case group,45 normal children from primary school were chosen as control group. Two groups children received the test of contour-integration,positional noise, temporal order memory, pattern memory. Results The ADHD double eyes' contour integration ( ( 1.62 ± 0. 81 ), ( 1.69 ± 0.87 ) ) were significantly lower than the control group' ( (2.02 ± 1.10), ( 1.98 ±0.81 )). There was no significant difference of double eyes' positional noise between case group( (1.98 ±0.89 ), ( 2.20 ± 1.10 ) ) and the control group ( ( 2.20 ± 0. 97 ), ( 2.30 ± 0. 83 ) ). The temporal order memory,pattern memory ( ( 1.89 ± 1.30), ( 1.18 ± 0.44) ) showed significantly lower in case group(P＜ 0.05 ) than that in control group ( ( 2.98 ± 1.25 ), ( 1. 44 ± 0. 66) ). Conclusion Results indicate that children with ADHD have deficiency in visual perception and the ability of visual information integration, and have significantly deficiency in visual working memory and executive-function.

Objective:To investigate the effect of silica gel column separation component of Artemisia asiatica (AEM-SC) on the maturation and immune function of mouse dendritic cells (DCs). Methods:Artemisia asiatica components were prepared by macroporous resin eluted with 70% ethanol, and then isolated by silica gel column to obtain AEM-SC. The contents of polysaccharides, flavonoids and triterpenes were quantified. Flow cytometry was used to detect the expression level of DCs surface molecules and antigen phagocytosis ability and to stimulate the proliferation of allogeneic T cells. ELISA method was used to detect the effect of DCs on cytokine secretion. Results:The contents of polysaccharides, flavonoids and triterpenes in AEM-SC were 10.12%, 5.7% and 3.62%, respectively. Functional tests showed that AEM-SC significantly reduced the expression levels of LPS-induced DCs surface molecules CD40, CD86 and MHC-II, reduced the expression levels of inflammatory cytokines IL-12p40, TNF-α and IL-6 (all P<0.05), improve the ability of phygocytosis ( P<0.01), and reduce the ability of DCs to stimulate the proliferation of CD4 +T and CD8 +T lymphocytes in the spleen of mice (all P<0.001). In the inflammatory mouse model experiment, AEM-SC significantly reduced the expression levels of DCs surface molecules CD40, CD86, CD80 (all P<0.001), and the expression levels of inflammatory cytokines TNF-α, IL-12p40 in serum (all P<0.01). Conclusions:AEM-SC can inhibit the maturation of DCs-induced LPS both in vitro and in vivo, indicating that AEM-SC has the immunosuppressive effect.

Objective:To evaluate the diagnostic and therapeutic value of bedside severe ultrasound in children with shock.Methods:Children who were diagnosed shock in the PICU of Shengjing Hospital of China Medical University from May 1, 2019 to April 31, 2020 were included in this study.Rapid ultrasound in shock (RUSH) exam was used to evaluate the morphology and function of heart, lung and abdomen of children with shock, so as to assist the diagnosis and treatment of shock.Results:Twenty-six children with shock were evaluated immediately according to the RUSH exam when they were admitted to hospital.Eight cases were diagnosed as septic shock, six cases as cardiogenic shock, six cases as hypovolemic shock and six cases as mixed shock.The left ventricular ejection fraction (LVEF) of children with cardiogenic shock was (26.5±8.24)%, and the width of inferior vena cava was greater than 10 mm.After the shock was corrected, LVEF increased to (32.17±26.11)%.However, the LVEF of children with septic shock was (73.25±1.28)% at admission and (50.12±31.41)% at shock correction.Nine cases (34.6%) found more B-lines in the lungs after fluid resuscitation for one hour in 26 children with shock.Among them, about 50% of the children with cardiogenic shock found more B-lines in their lungs one hour after fluid resuscitation, and 11 cases(57.9%) of the surviving children showed more B-lines after shock correction, but only six children could hear blisters after physical examination.Conclusion:According to RUSH exam, we can evaluate the volume status, cardiac function, volume responsiveness and focus on infection in children with shock, distinguish the type of shock earlier and more accurately, assist in guiding fluid resuscitation, and facilitate accurate and individualized fluid management and treatment of patients.
