Sphingosine kinase 1 (SphK1) plays critical roles in cell biological functions. Here we investigated the effects of SphK1 inhibitor SKI II on hepatoma HepG2 cell cycle progression and invasion. Cell survival was determined by SRB assay, cell cycle progression was assayed by flow cytometry, the ability of cell invasion was measured by Matrigel-Transwell assay and protein expression was detected by Western blotting. The results showed that SKI II markedly inhibited HepG2 cell survival in a dose-dependent manner, induced G1 phase arrest in HepG2 cell and inhibited cell invasion. SKI II markedly decreased the expressions of G1-phase-related proteins CDK2, CDK4 and Cdc2 and the levels of cell invasion-associated proteins MMP2 and MMP9. The results showed that SKI II inhibited cell cycle progression and cell invasion, implying SphK1 as a potential target for hepatoma treatment.

This study examined the effects of TRAIL-endostatin-based gene-radiotherapy on cellular growth, apoptosis and cell cycle progression in human vascular endothelial cells ECV304 in vitro. The expression of TRAIL and endostatin protein in ECV304 cells was detected by ELISA after the transfection of recombinant plasmid pshuttle-Egr1-shTRAIL-shES and X-ray irradiation. Then MTT assay was used for determining the cellular proliferation, and flow cytometry (FCM) plus Annexin V and propidium iodide (PI) double-staining or PI single-staining were employed for the detection of apoptosis and cell cycle progression. The results showed that expression of TRAIL and endostatin protein exhibited a time- and dose-dependent change in ECV304 cells after pshuttle-Egr1-shTRAIL-shES transfection in conjunction with irradiation. In the TRAIL-endostatin-based single- or double-gene-radiotherapy, the cell viability declined in a time- and dose-dependent manner, the percentage of cells at G(2)/M phase and apoptotic rate was increased, and the percentage of cells at G(0)/G(1) phase was lowered as compared with those receiving radiotherapy alone. Moreover, TRAIL-endostatin-based double-gene-radiotherapy demonstrated better effects on growth inhibition, promotion of apoptosis and induction of cell cycle arrest in ECV304 cells than single-gene-radiotherapy.

OBJECTIVEThis study aimed to observe the postoperative pain rate and degree of pain in preschool children with cleft lip and palate, and investigate the effect of nursing intervention on pain relief.

METHODSA total of 120 hospitalized cases of three- to seven-year-old preschool children with cleft lip and palate were selected from May to October 2011. The subjects were randomly divided into the control group and experimental groups 1, 2, and 3. The control group used conventional nursing methods, experimental group 1 used analgesic drug treatment, experimental group 2 used psychological nursing interventions, and experimental group 3 used both psychological nursing intervention and analgesic drug treatment. After 6, 12, 24, and 48 h, pain self-assessment, pain parent-assessment, and pain nurse-assessment were calculated for the four groups using the pain assessment forms, and their ratings were compared.

RESULTSThe postoperative pain rates of the four groups ranged from 50.0% to 73.3%. The difference among the four groups was statistically significant (P < 0.001). The differences among the control group and experimental groups 1 and 2 were not statistically significant (P = 0.871), whereas the differences among experimental group 3 and the other groups were statistically significant (P < 0.001).

CONCLUSIONPostoperative pain in preschool children with cleft lip and palate is common. Psychological nursing intervention with analgesic treatment is effective in relieving postoperative pain.

OBJECTIVETo evaluate the effectiveness of hypnotic and musical relaxation therapy and psychological consultation for parents of children with cleft lip and/or palate (CLP) and to provide a scientific basis of clinical-psychological treatment options.

METHODSSixty-six subjects with children with CLP participated in this study. The subjects were randomly assigned to a test group (n = 33) and a control group (n = 33). The test group was treated with hypnotic and musical relaxation therapy; the control group were subjected to psychological consultation. Anxiety and depression states were evaluated by using a self-rating anxiety scale (SAS) and a self-rating depression scale (SDS) before and after treatment was administered.

RESULTS1) The test group demonstrated a significant decrease in SAS and SDS scores (t = 2.855, P < 0.01; t = 2.777, P < 0.01). The control group showed a significant decrease in the SAS score (t = 1.831, P < 0.05) but failed to show a significant change in the depression score (t = 0.909, P > 0.05). 2) The test group yielded a higher percentage of remission indicated by the SDS scores than the control group (test group = 75.76%; control group = 60.61%; P < 0.05). The test group also displayed a higher percentage of remission indicated by the SAS scores than the control group (test group = 78.79%, test group = 69.70%; P < 0.05).

CONCLUSIONHypnotic and musical relaxation therapy can more effectively reduce the scores of the anxiety and depression states of the parents of patients with cleft lip and/or palate than psychological consultation.

OBJECTIVETo investigate the quality of life of cleft lip and/or palate children's parents and discuss the factors to provide the oretical basis for improving the quality of life of these parents and promoting the healthy growth of children with cleft lip and/or palate.

METHODSA total of 115 parents whose children had cleft lip and/or palate surgery treatment were selected as the experiment group, and another 198 parents (with healthy children having a similar age with those in the experiment group) as the control group. The experiment group was divided into three subgroups according to different types of cleft lip and/or palate: cleft Lip (CL), cleft palate (CP), cleft lip and palate (CLP). The experiment group and the control group were both divided into four subgroups according to age: 0-1, 1-3, 3-6 years old, and more than 6 years old. The experiment group and the control group were both divided into three subgroups according to education: junior middle school and the following, high school and technical secondary school, junior college degree or above. The GQOLI-74 scale was selected to assess the experiment group and the control group. SPSS 16.0 software was used to analyze data.

RESULTS1) The experiment group had no significant difference with the control group in terms of the overall score and the scores of various children ages. 2) The scores of every item had no significant difference in CL, CP, CLP subgroup (P > 0.05). 3) The quality of life scores and scores of psychological function dimension and social function dimension of parents with 3-6 years old patients were obviously lower than those of parents with more than 6 years old patients (P<0.05). The scores of social function dimension of parents with 0-1, 1-3, 3-6 years old patients were obviously lower than those of parents with more than 6 years old patients (P < 0.05). The other items had no significant difference. 4) The scores of material life dimension and social function dimension of parents with junior college degree or above were higher than those of parents with junior middle school degree and the following (P < 0.05). The scores of social function dimension of parents with high school and technical secondary school degree were higher than those of parents with junior middle school degree and the following (P < 0.05).

CONCLUSIONNo difference was observed in the quality of life between cleft lip and/or palate children's parents and normal group. The parents with the low age children with cleft lip and/or palate and low-levels of education need more help and support to improve quality of life.

Objective To explore the effect of multiple low dose radiation(LDR)on the apoptosis of splenocytes and immune factors in diabetes mellitus(DM)rats.Methods The rats were randomly divided into control,DM and DM + LDR groups.The irradiation doses were 25,50 and 75 mGy,and the irradiated times were 15.At the fourth weekend after the DM rats irradiated,the apoptotie rate and TCRαβ percentage of splenoeytes were detected by flow cytometry,and the content of IL-2 in both serum and supernatant of cultured splenocytes were detected by ELISA.Results Compared with that in the control,the body weight(BW)decreased in the DM and DM + LDR groups,particularly in DM group.The blood glucose(BG)level in the DM + LDR groups was higher than that in the control,but decreased significantly as compared with that in the DM group(P < 0.01).As compared with those in the control,the apoptotic rate in DM + 50 mGy(P < 0.05)and the content of serum IL-2 in DM + 75 mGy group(P < 0.01)all increased significantly,while the content of IL-2 in supernatant of cultured splenocytes decreased significantly in the DM + LDR groups.Compared with those in the DM group,the apoptotic rate and the percentage of TCRαβ in splenocytes in the DM + LDR groups(P < 0.01-P < 0.001)and the content of IL-2 in serum in DM + 50 mGy group(P < 0.01)decreased significantly.Conclusions The multiple LDR could weaken the loss of BW and increase of BG caused by DM,decrease the splenocyte apoptosis induced by DM,and regulate the immune factors.

Objective To construct the pshuttle-Egr-1-hSmac plasmid and transfect human breast cancer MDA-MB-435 cells,and to observe its radiotherapy enhancing effect on tumor cells.Methods The empty vector pshuttle and pshuttle-Egr-1-hSmac plasmid were transfected into MDA-MB-435 cells by liposomal.At different time(4,8,12,24 and 48 h)after irradiation with 2.0 Gy X-ray and 24 h after irradiation with 0.5 -5.0 Gy,the total RNA and protein were collected and extracted from these cells to analyze the Smac mRNA and protein expression levels with RT-PCR and Western blotting methods. The cells were divided into control, pshuttle, pshuttle-Egr-1-hSmac,2.0 Gy irradiation group, pshuttle + 2.0 Gy irradiation and pshuttle-Egr-1-hSmac+2.0 Gy irradiation groups.MTT method was used to evaluate cell proliferation,and the cell survival ability was measured with clone formation assay;Annexin Ⅴ/PI double staining and PI single staining were used to examine the apoptosis and cell cycle of MDA-MB-435 cells. Results There was no Smac mRNA expression in MDA-MB-435 cells in control and pshuttle groups,but the Smac mRNA expression levels in MDA-MB-435 cells in pshuttle-Egr-1-hSmac plasmid group were gradually increased with the time prolongation, and reached the maximum at 24 and 48 h;the Smac mRNA expression levels in MDA-MB-435 cells were increased gradually 24 h after irradiation of 0.5 - 5.0 Gy X-ray with the increasing of irradiation doses, and reached the maximum after 2.0 and 5.0 Gy irradiation. The Smac protein expression levels in pshuttle-Egr-1-hSmac plasmid group were increased gradually with the time prolongation,and reached the maximum at 24 h.The Smac protein expression lervels were increased 24 h afer irradiation of 0,0.5,1.0,2.0 and 5.0 Gy X-ray,especially in 5.0 Gy group. The MTT results showed that the A490 values in 2.0 Gy,pshuttle+2.0 Gy and pshuttle-Egr-1-hSmac groups 24, 48,and 72 h after irradiation were lower than those in control group(P<0.01);the A490 values of MDA-MB-435 cells in pshuttle-Egr-1-hSmac group after 1.0-5.0 Gy X-ray irradiation were lower than those in 0 Gy group (P<0.05 or P<0.01);the survival fraction(SF)in pshuttle-Egr-1-hSmac group was lower than those in control group (P<0.01).The percentages of the cells at G0/G1 and S phase in pshuttle-Egr-1-hSmac group were lower than those in 2.0 Gy group(P<0.01),the percentage of the cells at G2/M phase was higher than that in 2.0 Gy group (P<0.01);the apoptotic rate of the cells in pshuttle-Egr-1-hSmac group was higher than that in 2.0 Gy group (P<0.01).Conclusion X-ray irradiation can significantly increase the Smac mRNA and protein expression levels in MDA-MB-435 cells transfected with pshuttle-Egr-1-hSmac plasmid,inhibit the cell survival rate,and induce G2/M arrest and apoptotic increasing;Smac gene combined with radiotherapy could significantly increase the radiosensitivity of breast cancer cells.

Objective To investigate the toxicity-reducing and action-enhancing effects of total glucosides of paeony (TGP) on tripterygium glycosides (TG) in treating murine lupus nephritis (LN).Methods Chronic graft-versus-host disease (cGVHD) murine LN model was established.Modeling mice were randomly divided into three groups:LN group,TG group (in the dose of 30 mg?kg-1?d-1),and TG+TGP group (TG in the dose of 30 mg?kg-1?d-1 and TGP in the dose of 200 mg?kg-1?d-1),6 mice in each group.Another six normal mice served as control.Medication groups received corresponding medicine according to the experimental design,and mice in the normal control group and LN group received the same volume of saline,qd,for 4 weeks.After the treatment,the levels of 24-hour urinary protein excretion (UPE),blood urea nitrogen (BUN),serum creatinine (SCr),serum alanine transferase (ALT) and aspartate transferase (AST),and contents of superoxide dismustase (SOD),malondialdehyde (MDA),and glutathione peroxidase (GSH-Px) in liver tissue homogenate were measured.Meanwhile,the pathologic changes of kidneys in each group were detected.Results Compared with LN group,levels of UPE,BUN and SCr in TG group and TG+TGP group were decreased notablely (P
