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 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 study the effects of common percutaneous enhancers on transdermal permeability of cetirizine hy-drochloride(CET). METHODS:Using pH 7.4 phosphate buffer as receiving solution,accumulative permeation rate as index,mod-ified Franz diffusion cell was used to investigate the effects of common percutaneous enhancers on transdermal permeability of CET in skin of abdomen isolated from mice,such as azone (0.06%-2.5%),oleic acid (0.5%-10%),1,3-propanediol (0.5%-10%),propanetriol(0.5%-5%). RESULTS:1,3- propanediol had no improvement effect on the permeability of CET. 24 h accu-mulative permeation amount of CET in 0.06% azone,0.5% oleic acid and 1% propanetriol were the highest among same types, being 227.94,85.25 and 215.15 μg/cm2,respectively. CONCLUSIONS:Of four percutaneous enhancers,the transdermal enhanc-ing efficiencies from high to low are azone>glycerol>oleic acid>1,3-propanediol. Azone and glycerol have the conspicuous pene-tration enhancing effects.

Objective To investigate the role of T-type calcium channel in lidocaine-induced neuronal cytotoxicity . Methods SH-SYSY cell line was a gift from cell biology laboratory of our medical university. The cells were cultured in DMEM liquid culture medium at 37℃ in incubator filled with 5% CO2 , and randomly divided into 4 groups ( n = 66 each) : control group (group C)and M, L and ML groups were exposed to 5 μmol/L mibefradil (a T-type calcium channel blocker), 10 mmol/L lidocaine and 5 μmoL/L mibefradil + 10 mmol/L lidocaine for 24 h. Cell morphology was examined by electronic microscopy at 24 h of drug exposure. Cell viability (by MTT) and neuronal apoptosis (by flow cytometry) were detected immediately before and at 1, 6, 12 and 24 h of exposure to mibefradil or/and lidocaine.Results In C and M groups, the cells demonstrated dendritic protrusions, enlarged nerve processes and dense lattice. After being exposed to lidocaine for 24 h, the dendritic protrusions disappeared,the cells decreased in size, shrinked and became round; the cell viability was significantly decreased while the neuronal apoptosis increased. The lidocaine-induced changes were significantly attenuated by co-incubation with mibefradil. ConclusionT-type calcium channel is involved in lidocaine-induced neuronal cytotoxicity.

ObjectiveTo establish a rat model of nerve damage induced by intrathecal(IT) lidocaine.MethodsFifty-five adult male SD rats weighing 200-220 g were randomly divided into 5 groups (n =11 each):group normal control (group C); group dimethyl sulfoxide (DMSO)-the solvent(group D) and groups IT 5％,10％,15％ lidocaine (groups L5.10.15 ).IT catheter was successfully implanted without complication in groups D,L5,L1o,L15.DMSO,5％,10％ and 15％ lidocaine 20 μl were injected IT in groups D,L5,L10,L15 respectively.Motor dysfunction of hindlimb was assessed and scored (0 =normal,2 =complete block) and paw withdrawal threshold to mechanical stimulation (von Frey filaments) (MWT) and paw withdrawal latency to thermal nociceptive stimulus (TWL) were measured before (baseline) and at 1,2,3,4,5,7 d after IT administration in 8 animals in each group.Three animals in each group were sacrificed at 1 d after IT administration.The lumbar segment (L4-5) was removed for microscopic examination.ResultsThere was no significant difference in motor dysfunction score,MWT and TWL among groups C,D and L5.MWT was significantly increased and TWL prolonged at 1 and 2 d after IT administration in group L10,while in group L15 motor dysfunction score was significantly increased at 1,2 d after IT administration and MWT was significantly increased and TWL prolonged at 1,2,3 d after IT administration.There was significant histologic damage to spinal cord in groups L10 and L15.Conclusion Nerve damage can be induced by IT 10％ lidocaine.
