Objective To describe self-care agency and its influence factors of the patients with temporary ileum stoma. Methods The descriptive statistics of non-experimental study was performed in the study. The convenience sample consisted of 144 patients from 3 hospitals in Shanghai. The self-care agency was measured by the Colostomy Self-care Agency Scale. Results 144 cases of colorectal cancer temporary ileum stoma patients′ self-care ability scored an average of 57.02 ± 7.00, including self- care willingness (37.19 ± 4.04) points, self-care knowledge 17 points, self-care skills 3 points. The multiple stepwise regression analysis showed that seven factors were statistically significant including age, gender, culture level, living area, postoperative months, presence of complications, whether to accept professional nursing training or education. Conclusions Temporary ileum stoma in patients of rectal cancer with medium self-care ability, but self-care skill level is relatively not high and should be strengthen attention in patients with rectal cancer undergoing ileum stoma. Targeted nursing intervention should be carried out to improve the self-care ability and improve the quality of life of patients with stoma.

OBJECTIVE: To study the influence of PD173074 on proliferation and apoptosis of nasopharyngeal carcinoma. METHOD: With immunoblotting and RT-PCR, FGFR1 expression was detected in CNE, PONE1 and C666-1 cell lines. With MTT assay,the time-effect and dose-effect correlation between PD173074 and inhibition of CNE proliferation was evaluated. After PD173074 stimulation, the phosphorylation level of FGFR1 and AKT was detected with immunoblotting assay. Furthermore, influence of PD173074 on the activation of Caspase3 and Caspase9 was detected to study the underlying mechanism of why PD173074 could inhibit CNE proliferation. RESULT: FGFR1 has the highest expression in CNE cell line. Under incubation of 10 nmol/L PD173074 stimulation for 36 hours to 72 hours, the phosphorylation of FGFR1 and AKT was impaired significantly, which further reduced the proliferation of CNE. Moreover, PD173074 can activate the intrinsic apoptotic pathway by stimulating Caspase9,which activated Caspase3 and induced the apoptosis. CONCLUSION PD173074 could inhibit proliferation of nasopharyngeal carcinoma cell through reducing the phosphorylation of FGFR1 and AKT. Additionally, PD173074 can induce CNE apoptosis by activating intrinsic apoptotic pathway via cleaving Caspase9 and Caspase3.

Objective To investigate the effects of leptin on the oxidative damage in human retinal pigment epithelial (RPE) cells.Methods Human RPE cells (ARPE-19) were cultured in vitro,and randomly divided into control group and insulin resistance group.RPE cells were treated with 0,10,100 ng/mL leptin for 24,48,72 hours respectively.Then the levels of reactive oxygen species (ROS) expression in RPE cells were detected by 2',7'-dichlorofluorescin-diacetate (DCFH-DA),and the levels of 8-hydroxy-2′-deoxyguanosine (8-OHdG) expression in RPE cells were observed by immunocytochemistry (ICC),and the levels of human 8-oxoguanine DNA glycosylase 1 (hOGG1) expression in lysate were measured by Western blot.Results After 24,48,72 hours,the level of ROS (Control group:F=37.136,37.178,49.634; P＜0.05.Insulin resistance group:F=9.822,28.881,71.150;P＜0.05),8-OHdG (Control group:F =88.643,390.920,1039.276; P ＜ 0.05.Insulin resistance group:F =273.311,299.155,82.237;P＜0.05) and hOGGl (Control group:F=470.062,1073.113,295.456;P＜0.05.Insulin resistance group:F =240.032,592.389,527.760 ; P＜0.05) expression increased significantly with the increase of leptin concentration in control group and insulin resistance group.Under the same leptin concentration,the level of 8-OHdG has a trend that it was higher in the insulin resistance group than the control group.After 24 hours,the difference of hOGGl expression between control group and insulin resistance group was not significant (F=23.392,P＞0.05).After 72 hours,the level of hOGGl expression was significantly higher in the insulin resistance group than the control group (F=129.394,P＜0.05).The level of hOGGl expression was significantly higher at 48 hours than that at 24 hours and 72 hours (P＜ 0.05).Conclusion Leptin could induce the oxidative damage of RPE cells in normal and insulin resistance status.With the increase of leptin concentration and time extended,the degree of oxidative damage and its repair were both increased.The degree of oxidative repair increased with the increase of leptin concentration,but decreased with time extended.

Objective To study the effect of Gabapentin(GBP)on the transient receptor potential vanilloid l(TRPV1)in dorsal root ganglion (DRG)of rats with chronic constriction injury(CCI). Methods SD male rats were used to establish CCI model and randomly divided into 3 groups,the control group,the CCI group,and the CCI+GBP group. Mechanical allodynia and thermal hyperalgesia were measured to evaluate the es?tablishment of CCI model and the analgesic effect of GBP. At the postoperative 8 days,all rats were sacrificed and dorsal root ganglions were collect?ed for further RT?PCR and Western?blotting analysis to detect expression of TRVP1 in DRG. Results The mRNA and protein expression of TRPV1 were both significantly increased in DRG after CCI operation and GBP could decrease mRNA expression of TRPV1 gene in DRG after CCI. Conclusion The expression of TRPV1 was increased in DRG after CCI operation which was decreased after administration of GBP.

ObjectiveBy the study of histological feature of the regenerated nerve at different time after operation,to explore the mechanism of the peripheral nerve regenerationwhen the distal nerve stump is repaired by a smaller proximal end with artery sleeve briding.MethodsFour Wistar rats were served as the donors of arteris for bridging.Sixteen Wistar rats were randomized into 2 groups (n =8 per group).In control group,the right sciatic nerves were cut off and received epineurial suture.In experimental group,the right sciatic nerves received artery sleeve bridging in different size.HE staining was taken to observe the histological changes of the regenerated nerve at 7,14,21 and 28 days after operation.ResultsThe new regenerated axons need about 21 days to pass the bridging gap.Twenty-eight days after operation,the number of the regenerated axons in distal segment was greater than that of the proximal in the experimental group.The regenerated axons were matured and more regular.Conclusion The functional reserve of repaired nerve is exists when the proximal end is smaller than the distal in size by means of amplification effect.And the method of artery sleeve bridging provides a better situation for functional reserve.

BACKGROUND:High fat diet (HFD) can induce overweight and obesity,which have been considered to positively affect bone mineral density (BMD) in adults.However,it is unclear how HFD affects the bone development during childhood.OBJECTIVE:To determine the effect of HFD on bone development in young female mice.METHODS:Twelve female CD1 mice were fed with either HFD or normal fat diet (NFD) starting at 4-week of age for 10 weeks.The bone mineral content (BMC),BMD,fat and lean mass were examined in 14-week old mice using dual-energy X-ray absorptiometry,and bone biomechanical properties were also evaluated using three-point bending test.Serum concentration of bone metabolic markers was measured using enzyme immunoassay.Femora were sectioned in the transverse plane and stained with hematoxylin and eosin for observing the adiposity of bone marrow and changes in trabecular bone area.RESULTS AND CONCLUSION:The body weight and fat mass in HFD-treated mice were increased compared with those in NFD-treated mice,respectively.There were no significant differences between HFD-treated and NFD-treated mice in whole body BMD,BMC,bone area and lean mass.However,the spine BMC and bone area in HFD mice were significantly lower than that in NFD mice,while femoral BMD,BMC and bone area in HFD mice were significantly greater than that in NFD mice.But,there was no statistically different in bone biomechanical values between the two groups.Bone metabolic markers were lower in HFD mice than NFD mice,indicating the less active of bone metabolism in HFD mice.It is suggested that HFD can produce deleterious effect on bone during the active growing phase of young mice.Vertebral bone is more sensitive to this negative effect than cortical bone due to the decreased vertebral mineralization.Weight-bearing bone does not response sufficiently to compensate for the excessive weight gaining.
