Objective To investigate the current status analysis the risk factors of medical adhesive related skin injury(MARSI) in neonates in NICU, in order to provide guidance in prevention and nursing of the skin injury. Methods Convenience sampling five NICU in Shenyang, prospective investigate the incidence of MARSI of neonates during the NICU stay, and analysis the incidence , injury type distribution and risk factors. Results The incidence of MARSI in neonates in NICU was 12.8%(53/413);the major injury type of MARSI was epidermal stripping(47.2%,25/53)and skin tear(35.8%,19/53) in mechanical injury;Logistic analysis showed that the independent risk factors of MARSI were the use of stomach tube, dehydrate skin and blue light therapy (χ2=5.953, 9.806 and 7.568, P<0.05). Conclusions MARSI is frequency interrupted in neonates during the NICU stay, correct selection of medical adhesive products, application of suitable paste and remove skills are helpful to reduce the incidence of MARSI in neonates during the NICU stay.

Background and purpose: High-dose chemotherapy followed by autologous stem cell transplantation (auto-HSCT) is considered as the ifrst line treatment for patients with relapse/refractory lymphoma after conventional chemotherapy. However, most of these patients still relapse the second time. The purpose of this study was to analyze the efifcacy of the consolidation chemotherapy after autologous stem cell transplantation (HSCT) refractory/relapse lymphoma in high risk. Methods:A total of 38 patients with relapsed/refractory lymphoma including Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) were included, who were underwent auto-HSCT in our transplan-tation department from Jan. 2010 to Dec. 2013. In treatment group, 19 patients received 2 courses of consolidation che-motherapy after auto-HSCT every 2 to 3 months, with the regimen of mini-BEAM or modiifed mini-CBV. Another 19 patients had no chemotherapy after auto-HSCT as control group. Results:The median follow-up duration was 17.2 and 7.5 months in the treatment and control group respectively. The follow-up data demonstrated prolonged progression-free survival (PFS) in the treatment group than the control group [24.7 months vs 7.8 months, P=0.029 under intend-to-treat analysis ITT;24.7 months vs 5.2 months, P=0.01 under per protocol analysis(pp)]. There is also a trend of improved overall survival (OS) in the treatment group (P=0.055, ITT). Conclusion:Consolidation chemotherapy after auto-HSCT for refractory/relapsed lymphoma patients delay the relapse and tend to improve the overall relapse rate.

Objective To evaluate the effect of using serf-designed facial support in prone position for patients after vitrectomy and silicone oil tamponade. Methods 100 patients with vitrectomy and sili-cone oil tamponade were randomly divided into the experimental group and the control group with 50 pa-tients in each group. The self-designed facial support in prone position was used in the experimental group, while the routing nursing measure was used in the control group. The ocular adverse effect and re-lapse rate were compared between the two groups. Results The incidence rate of corneal edema, in-creased intraocular pressure and retinal redetachment in the experimental group was higher than those in the control group, the time of keeping position in the experimental group was longer than that in the con-trol group. Conclusions Self-designed facial support in prone position can decrease discomfort and pain caused by compulsive position, reduce the incidence of complications, improve retinal attachment and increase the successful rate for the patients with vitrectomy and silicone oil tamponade.

Objective Use MRS technology to detect in vivo Glx concentration of Zelanian rabbits' muscle.Methods Tweenty Zelanian rabbits are collected,SS-PRESS sequence is applied to check their Signal Ratio of Glx/TCr.After deta collection,draw blood and do the biopsy of the FOV's muscle tissue immediately.Mensurate the rabbits' blood Crn concentration,Glx and TCr concentration in muscle.Research the correlation between the above factors,attempt using the MRS Glx/TCr Signal Ratio and blood Crn concentration to predict muscular Glx concentration.Results The correlation between MRS Glx/TCr Peak Ratio and muscular Glx/blood Crn concentration ratio is 0.681.A linear regression formula is obtained: The predict Value of Glx concentration in muscle(?mol/g muscle)= Glx/TCr Peak Ratio ? Crn concentration in blood(mg/dl)?28.754-0.631.Conclusion Using a linear regression formula to predict the muscular Glx concentration,the results can reflect the level of the true values without biopsy,though it's not accurate enough for quantitatively analysis.

Objective To investigate the relationship between acute radiation proctitis and radiation dose,volume as well as radiation time,in the process of intensity-modulated radiation therapy (IMRT) for the cervical cancer patients.Methods A total of 51 patients with locally advanced cervical cancer were enrolled from January 2011 to December 2013.Those patients were then classified into grade 1 to 4 groups,according to the RTOG/EORTCtoxicity grading standard.The exposure dose volume and the average dose of rectum under the standard plan were evaluated with dose-volume histogram (DVH).The ANOVA test was used for analyzing Dmax,D mean,D1 cm3,D2cm3,D40 and V40 values of rectum and the average exposure dose of rectum.Results The average time of acute radiation proctitis with clinical symptoms was (23.06 ± 12.01) d after radiotherapy.Dmaxvalues of rectum in grade 2 group was lower than those in grade 3 and 4 groups (F =5.268,P ＜ 0.05).Moreover,D1 cm3 and D2 cm3 values of rectum in grade 1 and 2 groups were also lower than those in grade 3 and 4 groups (F =4.893,4.406,P ＜ 0.05).There was no statistically significant difference between D40 and V40 values.Conclusions The acute radiation proctitis could be frequently found around 20 days during the IMRT for cervical cancer patients.Mild and moderate acute radiation proctitis are more common,while severe acute radiation proctitis is rare.Minimizing Dmax,D1 cm3 and D2 cm3 values of rectum might reduce the incidence of severe acute radiation proctitis in cervical cancer patients receiving IMRT.
