Objective To deeply understand the postoperative real experience of colostomy patients on ostomy management, and try to explore the difficulties and needs after discharge in order to provide theoretical basis for postoperative nursing intervention. Methods By using phenomenological research method, 10 colostomy patients were interviewed face- to- face, and the content was analyzed by Colaizzi method. Results Three themes were concluded: self- care obstacle related to ostomy; self- growth brought by ostomy; expectations for social support and family care. Conclusions Colostomy patients have to face so many problems after operation on ostomy management, and hospital, society and family have responsibility to help patients adapt to ostomy as soon as possible and improve their quality of life.

Objective To investigate the efficacy and safety of low-dose ammonia sulfur-sulfur-resistant treatment.Methods 120 patients with initial depression were randomly divided into a group(40 cases), the estercalyptrin group(40)and the drug group(40).The treatment was treated by the treatment of the ammonia sulfonate, 20 mg/d, 20 mg/d, and 20 mg/d of escitaloplan tablet.The clinical efficacy and response scale(TESS)was evaluated with the Hamilton depression scale(TESS)in the treatment of 1, 2, 4 and 8 over the weekend.Results Three groups showed significant improvement(P<0.01)during the 8th weekend of treatment of the HAMD scores.Grade 1 and 2 weekend, combined treatment group compared with single drug group score had significant difference(P<0.01), and the contrast between the single drug groups had no significant difference, 4 score over the weekend, and comparison between the three way were significant differences(P<0.05), 8 scores over the weekend, and share with escitalopram phthalein general group is no difference, but tolbutamide will benefit group compared with the other two groups had significant difference(P<0.01).Conclusion Small doses of tolbutamide will benefit has antidepressant effect, but the long-term curative effect of treatment is better than the amount of escitalopram citalopram, and share small doses of escitalopram citalopram tolbutamide will benefit can obviously accelerate the antidepressant treatment work.

AIM: To investigate the effect of digoxin on apoptosis and growth in human gastric carcinoma SGC7901 cells and its possible mechanism.METHODS: SGC7901 cells were incubated in the medium containing digoxin at different concentrations for 24 h.CCK-8 assay was employed to detect the anti-tumor effect of digoxin on SGC7901 cells, and IC50 value of digoxin was calculated.Flow cytometry was used to determine the apoptosis and the cell cycle.Western blot was used to analyze the protein levels of c-Src, p-c-Src(Tyr416), Akt, p-Akt(Ser473), ERK1/2 and p-ERK1/2 (Tyr204).The mRNA expression of c-Src was by RT-PCR.RESULTS: As the concentration of digoxin increased, the cell viability was reduced gradually starting at 50 nmol/L digoxin treatment (P<0.05).The cell viability was reduced to the lowest extent by exposure to 500 nmol/L digoxin (P<0.05).The IC50 value of digoxin was 191.45 nmol/L for 24 h.After treatment with 200 nmol/L digoxin for 24 h, the apoptotic rate and the proportion of G0/G1 phase were significantly increased (P<0.05), the phosphorylated levels of c-Src, ERK1/2 and Akt declined (P<0.05), the mRNA and protein levels of c-Src were down-regulated (P<0.05) and the ability of migration was weaker (P<0.05) than that in control group.CONCLUSION: Digoxin may suppress the growth and induce the apoptosis of human gastric carcinoma SGC7901 cells by inhibiting the expression of c-Src gene and down-regulating the phosphorylated levels of ERK1/2 and Akt.

AIM: To investigate the effect of suberoylanilide hydroxamic acid (SAHA) on the apoptosis of hu-man small-cell lung cancer H446 cells and its possible mechanism.METHODS: H446 cells were incubated in the medi-um containing SAHA.CCK-8 assay was used to detect the anti-tumor effect of SAHA on the H446 cells, and IC50 values of SAHA were calculated.Flow cytometry was used to analyze the apoptosis.After Notch3 gene was silenced, the pro-apopto-tic effect of SAHA on the H446 cells was inhibited ( P <0.05).Eukaryotic expression plasmid containing N3ICD was transfected into the H446 cells, so that N3ICD was expressed in the H446 cells.The mRNA expression of Notch3 was measured by RT-PCR.The protein levels of Notch3, N3ICD, Puma and cleaved caspase-3 were determined by Western blot.RESULTS: SAHA remarkably reduced the cell viability in a dose-dependent manner (P <0.05), and the IC50 value of SAHA was 1.91 μmol/L.SAHA induced apoptosis in a dose-dependent manner (P <0.05).The expression of Notch3 gene was negative in the H446 cells, SAHA reactivated Notch3 gene and Notch3 pathway in a dose-dependent manner (P <0.05).Notch3 knockdown inhibited apoptosis induced by SAHA (P <0.05).Over-expression of N3ICD up-regula-ted the protein levels of Puma and cleaved caspase-3.CONCLUSION: SAHA induces apoptosis in human small-cell lung cancer H446 cells by activating Notch3 pathway and up-regulating the protein level of Puma.

AIM To investigate the effect of allicin on the regulation of VEGF mRNA expression in human hepatocellular carcinoma cells. METHODS Hepatocellular carcinoma cells were treated with the concentration 10 ?g?L -1 allicin in culture medium,and then the relative VEGF mRNA level at 8 h in human hepatocellular carcinoma cells was evaluated by reverse transcriptase polymerase chain reaction using HPRT(hypoxanthine phosphoribosyltransferase)as an internal control standard. RESULTS The expression of VEGF gene mRNA was inhibited obviously by allicin. Compared with control group, the relative expression level of VEGF gene mRNA was decreased by about 66 36%( P

ObjectiveTo observe andanalyze the clinical efficacy of needle knife treatment for knee meniscus injury from improving knee biomechanical balance and to provide a therapeutic basis and method for clinical practice.MethodOne hundred patients (112 knees) with knee meniscus injury meeting the inclusion criteria were allocated, in order of visits, to observation and control groups, 50 cases each. They were treated with a needle knife and an injection of sodium hyaluronate injectio into knee joint cavity, respectively. Changes in the indices were observed and assessed in the two groups by recording the plantar pressure analysis score and the knee function score before and after treatment and at follow-up. The clinical therapeutic effects were evaluated in the two groups.ResultThemaximum load, time integral difference value and load ratio around the knee joint decreased significantly in both observation and control groups after treatment and at follow-up (P<0.05). The regulating effect on knee joint force balance was better in theneedle knife group than in the control group (P<0.05). The improving effect on knee joint function was significantly better in the observation group than in the control group (P<0.01). The excellence rate was significantly higher in the observation groupthan in the control group after treatment and at follow-up (P<0.05).ConclusionNeedle knife treatment restores the function of the knee joint by loosing focal soft tissues around the knee joint, improving knee joint load imbalance and correcting the mechanical equilibrium around the knee joint in patient with knee meniscus injury. It has a definite curative effect on the disease.

ObjectiveTo evaluate the local failure and the impact on survival by prospectively comparing involved field radiotherapy (IFRT) and elective nodal irradiation (ENI) in combination with concurrent chemotherapy for locally advanced non-small cell lung cancer ( LA-NSCLC ).Methods LANSCLC patients were treated with 2 cycles of carboplatin ( AUC =5 - 6,d1 ) combined with paclitaxel ( 175mg/m2 ),followed assessment without distant metastasis,then randomized into IFRT (45 patients) or ENI (54 patients) arm.IFRT included primary tumor,ipsilateral hilar and positive mediastinal lymph nodes;ENI included the primary lesion,ipsilateral hilar,hilateral mediastinal lymph node drainage and bilateral supraclavicular area.The prescription dose was given as high as possible with V20 ≤35％ and spinal cord dose ≤50 Gy,combined weekly paclitaxel 40 mg/m2 concurrent chemotherapy.The Kaplan-Meier method was used to estimate survival data and the log-rank method was used to test distribution of survival time between arms.ResultsThe follow-up rate was 99％.49,29 and 17 patients were followed-up for 1-,2-and 3-year,respectively.More patients from group IFRT received ＞60 Gy than ENI (49％ vs.26％,x2 =5.59,P =0.018 ).The local failure rates were 29％ and 36％,respectively ( x2 =0.46,P =0.497 ).The 1-,2-and 3-year local tumor progression-free survival rates were 76％,69％,65％ and 80％,53％,49％ ( x2 =0.74,P =0.389),respectively; the 1-,3-and 5-year overall survival rates were 80％,41％,33％ and 69％,32％,13％ (x2 =3.97,P =0.046),respectively.There were no significant differences in acute and late toxicities between the arms ( x2 =3.910 - 0.155,P =0.142 - 0.925 ).ConclusionsIFRT improved radiation dose and survival rate and did not increase the failure of elective lymph node region compared with ENI.The toxicities were no differences between IFRT and ENL Further investigation with big size sample is warranted.
