OBJECTIVE:To evaluate the application situation of anesthetic sedative agents in our hospital.METHODS:11945prescriptions of anesthetic sedative agents in inpatient department of our hospital during the period of2001～2003were statistically analyzed.RESULTS:There were5kinds of commonly used anesthetic sedative agents in3dosage types alto-gether;the anesthetic sedatives agents were mainly used in patients ranging from40～50years old;the drug use index(DUI)of all the kinds were all less than1,with the DUI of the majority at no more than0.5.CONCLUSION:Anesthetic sedative dosage for the treatment of cancer of late stage is lower than one needed,which suggests that sufficient dosage should be given to the cancer suffering patients by the physician.

AIM:To investigate the inhibitory effect of rabbit lens epithelial cell(RLEC)survival and growth by propylene glycol mannate sulfate(PGMS)on the rabbit capsular bag in vitro.METHODS;Capsular bags were prepared from rabbit eyes after extracapsular cataract extraction(ECCE)and incubated in 0.2,0.4,0.8g/L PGMS in 2,5,10 minutes incubation periods.After treatment,the capsular bags were cultured for 7 days in Dulbecco minimum essential medium(DMEM)supplemented with 50mL/L fetal calf serum(FCS).The specimens were examined with light microscopy and transmission electron microscopy(TEM).Capsular bags without receiving PGMS only served as controls.RESULTS:PGMS inhibited the proliferation of RLEC in the manner of concentration and time dependentment.At the threshold protocol of incubation in PGMS at 0.8g/L for 5 or 10 minutes,proliferative activity of cells were largely arrested and nearly no RLEC was seen on the posterior capsule(P＜0.05).Control group had no effect on structure and proliferative activity of RLEC,and the growth proceeded rapidly so that the posterior capsule were totally covered by a confluent monolayer of cell by the end of 7 days.Under TEM,the cells in the control group were tightly arrayed with clearly defined cellular boundary and structure;while cellular deformity and undefined intracellular structure could be seen in the 0.4g/L and 0.8g/L experimental groups.CONCLUSION:PGMS can effectively inhibit the proliferation of RLEC.

Objective To explore the effect of evidence-based nursing on improving the compliance of chronic obstructive pulmonary disease (COPD) patients with noninvasive positive pressure ventilation. Methods Forty-five patients hospitalized in the first half of the year were assigned as control group and another 45 patients hospitalized in the second half of the year were as experiment group. The control group was treated with traditional nursing methods. In the experiment group, a nursing panel was set up to analyze the causes of noncompliance of COPD patients with noninvasive positive pressure ventilation and gave care to the patients based on the analyses. The two groups were compared in terms of adverse reactions and the compliance with treatment. Result The rates of compliance with treatment and adverse reactions such as fear and anxiety , the man-machine confrontation and flatulence in the experiment group were significantly lower than those of the control group obviously (P<0.05). Conclusion The evidence-based nursing can reduce the incidence of adverse reactions , and enhance the compliance of COPD patients with noninvasive positive pressure ventilation effectively.

Objective:To establish a method for the content determination of total nitrogen in Nidus Vespae by salicylic acid and sodium hypochlorite spectrophotometry. Methods:The content of total nitrogen in Nidus Vespae from different areas with various batches was detected. Nidus Vespae was treated with sulfuric acid and hydrogen peroxide, and colored by salicylic acid and sodium hypochlo-rite. Using ammonium chloride as the control sample, the content of total nitrogen in the samples was tested at 650 nm. To ensure the method reliability, single factor experiments were performed to study the effects of temperature, reaction time and reagent dosage; or-thogonal experiments were used to screen optimum amounts of phosphate buffer solution, sodium salicylate solution and sodium hypo-chlorite solution. Results:The results showed that the optimum temperature was ambient, and the optimum time was 1. 5h. The opti-mum amount of phosphate buffer solution , sodium salicylate solution and sodium hypochlorite solution was 4 ml,7 ml and 1. 5 ml, re-spectively. The linear range of total nitrogen was 0. 06-0. 78 μg·ml-1(r=0. 9998), and the average recovery was 100. 98% (RSD=2. 10%,n=6). Conclusion:The method can be used to determine the total nitrogen content in Nidus Vespae. The total nitrogen content in Nidus Vespae is various in various areas with different batches.

Objective To explore the effect of nursing intervention on cerebral trauma patients in recovery phase. Methods 156 cerebral trauma patients who had more than 6 months course of disease received rehabilitation training and nursing care, and their activities of daily living (ADL) were accessed by modified Barthel index. Results The score of ADL in patients who had course of disease about 6~12 months was lower than patients who had more than 12 months course (P<0.05) before nursing care. The scores improved in both groups after nursing care (P<0.05), and there was no significant difference between 2 groups (P>0.05). Conclusion Rehabilitation training and nursing care may facilitate the recovery of ADL of cerebral trauma patients in recovery phase.

Objective To investigate the level of illness uncertainty and coping styles of parents of children with diabetes mellitus and their relationship, and provide theoretical basis of clinical intervention. Methods Totally 155 patients of children with diabetes mellitus were investigated with General Information Questionnaire, Parents′ Perception of Uncertainty Scale (PPUS) and Coping Health Inventory for Parents (CHIP) to analyze the correlation between illness uncertainty of parents and its influencing factors and coping styles. Results The total score of illness uncertainty was 80.15±10.38 in parents of children with diabetes mellitus. There was significant difference in total uncertainty score in parents with different number of children, parent′s age, education degree, profession, economic conditions and locations (P < 0.05). Coping style, education and Parent′s age entered into the multiple linear regression equation of illness uncertainty, predicting 23.2% of total variation in illness uncertainty. The level of illness uncertainty was negatively associated with coping styles (P < 0.01). Conclusions The illness uncertainty was at higher levels in parents of children with diabetes mellitus. Clinical nurses should measure illness uncertainty of parents of children with diabetes mellitus and improve their coping capacity to reduce illness uncertainty, so as to provide better services of family and promote the quality of life for children .
