Objective To evaluate the effect of transcatheter arterial chemoembolization (TACE) and delayed surgery for infant hepatoblastoma.Methods TACE was performed with the initial digital subtractive angiography (DSA) under general anesthesia 1-3 times in 8 infants with huge hepatoblastoma, whose age was 2 to 12 months. DSA was done via arterials in hepatoblastoma each time before chemoembolization. The arterials were perfused with chemodrugs and suspensions in ultrasome iodized oil , and were blocked with spring rings. DSA findings indicated that the tumor shrank without new tumorous arterials after 1 month in 6 cases, and 4 of them showed no tumorous staining, and the delayed surgery was performed successfully 1 week later in 6 infants. One boy underwent systemic chemotherapy alone during 6 months after 3 times of TACE. Results TACE therapy did not encounter any major technical problem or toxic reaction caused by chemotherapy. The following DSA test 4 weeks later did not detect any new tumorous vessels in 6 cases. Six children received TACE and surgery had been followed-up with no tumor recurrence for months averagely. The boy underwent TACE and venous chemotherapy for 6 months , without surgery , had been followed-up for 48 months until the present report. CT, AFP and DSA did not show any hints of tumor recurrence. Six cases receiving 3 times TACE combined with surgery survived without tumor recurrence. Conclusions TACE is a very effective, safe and helpful therapy for hepatoblastoma, which stressed the repeated use of spring ring to block tumor vessels lastingly if necessary. If surgery is required, DSA test is needed beforehand to detect new tumorous vessels or neoplasm. If there is any , TACE is repeated. TACE combined with surgery may provide an additional promising choice in the treatment of hepatoblastoma, and repeated TACE alone may cure hepatoblastoma in infants.

Objective To investigate the effect of individual nostalgia therapy on positive feelings and sadness of the spouses of postoperative patients with esophageal cancer. Method From June 2014 to June 2015, 60 hospitalized patients and their 60 spouses were set as control group. Routine health education and guidance were conducted once or two times a week for 7 weeks. Another 60 cases of hospitalized patients and their 60 spouses during July 2015 and June 2016 were set up as observation group. The patients were treated with the same nursing intervention as in the control group, and their spouses were subjected to individual nostalgia treatment once a week for 7 weeks. Before the intervention (postoperative day 2) and 7 weeks after the intervention, the positive aspects of caregiving (PAC) and the Margit-Meuser caregiver grief ineventary short form (MM-CGI-SF) were used to investigate their positive feelings and sadness. Result The score on spouse's positive feelings in the observation group after intervention was significantly higher than those of the control group and that of the observation before intervention (P < 0.01). Conclusion Individual nostalgia can effectively improve the feelings of the spouses of esophageal cancer patients and reduce their grief.

The G protein-coupled estrogen receptor (GPER), also known as G protein-coupled receptor 30 (GPR30), was identified in the recent years as a functional membrane receptor different from the classical nuclear estrogen receptors. This receptor is widely expressed in the cortex, cerebellum, hippocampus, heart, lung, liver, skeletal muscle, and the urogenital system. It is responsible for the mediation of nongenomic effects associated with estrogen and its derivatives, participating in the physiological activities of the body. The present study reviews the molecular structure, subcellular localization, signaling pathways, distribution, and function of GPER in the male reproductive system.

OBJECTIVEEffects of ginsenoside Rb1, Rg1 and Re on neurotrophic factor signal transduction pathway using liposome-mediated transfection of eukaryotic cells approach.
METHODThe injury model was established by treating SH-SY5Y cells with 0.6 mmol x L(-1) of corticosterone (CORT) by 24 h. SH-SY5Y cell were pretreated with CORT for 30 min followed by co-treated with 120,60 and 20 micromol x L(-1) of Rb1, 120, 80 and 40 micromol x L(-1) of Rg1 and 120, 80 and 40 micromol x L(-1) of Re for 24 h. Cells viability was determined by Cell Counting Kit (CCK) assay. CREB expressing Luciferase reporter gene was constructed and transfected with plasmid containing hRaf, hcAMP, hAkt, hCaMK gene into human embryonic kidney (HEK293) cells using liposornal transfection reagent lipofection 2000. The expression of CREB before and after it addion of Rb1, Rg1 and Re was examined by Luc assay system and Western blotting.
RESULTCompared with normal control group, CORT significantly decreased the viability of SH-SY5Y cells to 67.21% (P < 0.01). CCK results show that Rb1 (60 micromol x L(-1)), Rg1 (80 micromol x L(-1)) and Re (80 micromol x L(-1)) on SH-SY5Y cells have significant protective effect (P < 0.01). Lucassay and Western blotting results show that the gene and protein levels of CREB increased significantly through the pathway of Raf and Akt with Rb1 and Rg1 (P < 0.01), Re can increase significantly the gene and protein levels of CREB through the pathway of Raf and CaMK II.
CONCLUSIONRb1, Rg1 and Re protects SH-SY5Y cells from CORT-induced damage and the neuroprotective mechanism may be associated with the Raf-CREB, Akt-CREB and CaMK II -CREB pathways.
