Azone and glycerol have the conspicuous pene-tration enhancing effects.

Objective The aim of this study was to describe nursing student-patient relationship in Yunnan province,and study its influencing factors and practice effectiveness.Methods The multi-phase stratified cluster random sampling method was adopted to investigate 483 internship nursing students in two first class hospitals in Yunnan province.Results Among 483 nursing students,379 (78.5％) students belonged to facilitative relationship,101 (20.9％) students belonged to authoritative relationship,and 3 (0.6％) students belonged to mechanistic relationship.Sociodemographic data and factors related to three type of relationship showed no statistical significance among three types of nursing students.But student's personal and professional growth,student's increased confidence and self-esteem demonstrated statistical significance among three types of nursing students.In student's personal and professional growth,students of authoritative relationship got the lowest score (3.96±0.78) compared with students of mechanistic relationship and facilitative relationship [(4.17±0.29),(4.17±0.54)],F=4.82,P ＜ 0.01.In student's increased confidence and self-esteem,no significant difference was seen.Conclusions Nursing students' perceptions of student-patient relationship are mostly facilitative.And students' personal and professional growth and confidence and self-esteem increased obviously through internship for students with facilitative student-patient relationship.

Objective To observe the relationship between degree of venous injury and the indwelling time by injection of chemotherapy drugs with intravenous catheter system. Methods Totally 43 New Zealand rabbits were selected as the study sample. Among them, three rabbits were chosen by lot as a blank control, the others were evenly divided into two groups randomly. The veins at the edges of the two ears were taken out as the tested blood vessels for the infusion with intravenous catheter system. The two groups were injected respectively with physiological saline and chemotherapy drugs once daily, and then blocked with heparin salt water. After intraperitoneal anaesthesia, pathological sections were prepared by taking live samples from the ear vein where intravenous catheter system puncturing on the 2nd, 4th, 6th,8th and 10th day of transfusion. And inflammation and thrombosis in the vein had been observed under the light microscope. Results In the same indwelling time, the inflammatory response of the two groups was compared: no difference on the 2nd day; difference was seen on the 4th、6th and 8th day; but again no difference on the 10th day. Thrombosis compared: no difference on the 2nd, 4th day, but difference was seen on the 6th, 8th and 10th day. Conclusions Chemotherapy drugs has a strong irritant on blood vessels.The indwelling time should not be too long, generally advisable 2 days,even if no abnormal response is observed locally by the naked eye.

Objective To evaluate the effect of oxycodone on migration of human colon cancer cells and the role of μ and κ receptors.Methods The human colon cancer HCT116 cells at the logarithmic growth phase were seeded in 24-well or in 6-well plates at a density of 1 × 106 cells/mnl (0.5 ml/well or 2 ml/well,144 wells in total).The cells were divided into 6 groups (n=24 each) using a random number table:control group (group C),1,5 and 10 μmol/L oxycodone groups (group O1,group O2 and group O3),oxycodone plus μ receptor antagonist CTOP group (group O2+CTOP) and oxycodone plus κ receptor antagonist nor-binaltorphimine group (group O2+BNI).The cells were incubated for 24 h with oxycodone 1,5 and 10 μmol/L in O1,O2 and O3 groups,respectively.The cells were incubated for 24 h with 5 μmol/L oxycodone plus 20 μmol/L CTOP and 5 μmol/L oxycodone plus nor-binahorphimin 20 μmol/L in O2+CTOP and O2+BNI groups,respectively.The invaded and migrated cells were counted,and the levels of Ras homolog gene family member A (RhoA),Rho-associated protein kinase 1 (ROCK1),matrix metalloproteinase-2 (MMP-2) and MMP-9 were detected.Results Compared with group C,the number of invaded and migrated cells was gradually decreased,and the levels of RhoA,ROCK1,MMP-2 and MMP9 were gradually decreased in O1,O2 and O3 groups (P＜0.05),and no significant change was found in the parameters mentioned above in group O2+BNI (P＞0.05).Compared with group O2,the number of invaded and migrated cells was significantly increased,and the levels of RhoA,ROCK1,MMP-2 and MMP9 were increased in group O2 + BNI (P＜0.05),and no significant change was found in the parameters mentioned above in group O2+CTOP (P＞0.05).Conclusion Oxyc odone can inhibit the migration of human colon cancer cells,and the mechanism is totally related to inhibition of RhoA/ROCKl signaling pathway activation after activating κ receptors,but not related to μ receptors.

Objective To explore the clinical signiifcance of combined detection of thyroid stimulating hormone (TSH) and free thyroxin (FT4) in dried blood spots in screening for congenital hypothyroidism (CH) in neonates. Methods The TSH and FT4 levels in dried blood spot were measured by time-resolved lfuorescence immunity in live born neonates from June to December 2013. If the screening was positive, the blood was drawn and the serum TSH and FT4 were measured and compared with the results from dried blood spots. Results In a total of 31 199 neonates screened, 12 cases were diagnosed with CH and the prevalence rate of CH was 1/2 600;4 cases were hyperthyropinemia and no pituitary CH was detected. There was no signiifcant difference between TSH or FT4 levels in dried blood spot and those in serum in neonates diagnosed with CH (P>0.05). Conclusions Combined detection of TSH and FT4 in dried blood spot can be used for neonatal screening of CH. It can be applied for early distinguishing CH from hyperthyropinemia, and also helpful for early diagnosis and treatment of central CH.
