Objective To establish a new method for rapid detection of electrolytes based on micro spectrometer and dry reagent.Methods The liquid electrolyte reagent was lyophilized for the preparation of reagentin powder form,which was then sealed into a detector cup of micro spectrometer for later experiment.During determination,the detector cup,in which the specimens and diluents were added to the dry reagent,was put into the detector slot of micro spectrometer,the contents in the detector cup were then well mixed by the magnetic stirring system of micro spectrometer and incubated for 6min with the heating system.Afterwards,the A values of potassium ion,sodium ion and chloride ion were detected respectively at 620nm,405nm and 456nm following the reaction principles of turbidimetry,enzymatic method and chemical method.Based on the findings of those detections mentioned above,the performance of the electrolytic dry reagent was evaluated,and the results were then statistically analyzed.Results The linear range of each parameter could meet the demand for clinical analysis,and the dry reagents had good reaction stability for 90 days after being lyophilized,with the intra-assay coefficient variation(CV) less than 4%,inter-assay CV less than 5%,and the recovery rate from 95% to 105%.No obvious interference was observed in the determination results under the circumstance that the serum TB was less than 290.40?mol/L and the TG was less than 11.20mmol/L.The detection results by this method were well correlated with that of dry chemical analysator VITRO S-250(R≥0.98).Conclusion The method is accurate and reliable in determining the serum electrolytes,and its process is simple process and convenient to carry out.Therefore,it can satisfy the condition for field aid as well as primary care.

Objective To explore the clinical effect of psychological nursing pathway for patients with hepatocellular carcinoma (HCC) who are receiving 125I particle implantation therapy.Methods A total of 130 HCC patients,who were scheduled to receive 125I particle implantation therapy,were randomly and equally divided into the study group and the control group with 65 patients in each group.Traditional routine psychological nursing method was conducted for patients of the control group,while routine psychological nursing that was based on psychological nursing pathway was carried out for patients of the study group.The patient's conditions of both groups were evaluated by using self-rating anxiety scale (SAS),trait coping style questionnaire (TCSQ) and the quality of life assessment scale (SF-36).The results were statistically analyzed with t test.Results After nursing intervention,SAS scores of the study group and the control group were (43.76±6.25) and (46.16±7.19) points respectively,the difference between the two groups was statistically significant (t=-3.92,P＜0.001).The PC and NC values of the TCSQ score in the study group were (41.61±4.82) points and (20.53±5.88) points respectively,while those in the control group were (37.32±4.62) and (22.80±6.93) respectively,the differences between the two groups were statistically significant (t=5.944 and t=-3.316 respectively,P＜0.01).One month after discharge,the mental health scores of the study group and the control group were (74.58±8.68) points and (71.53±8.16) points respectively,the emotion function scores were (79.46±10.05) points and (75.13±15.09) points respectively,and the differences in both mental health score and emotion function score between the two groups were statistically significant (P＜0.05).Conclusion Standardized psychological nursing pathway can make nurses more clear about the content of psychological nursing work and enable nurses to actively plan and complete psychological nursing care measures,so that patients can get prospective,individual and comprehensive psychological care to alleviate his or her negative emotion,and to improve the quality of life.
