A kinetic method for the detemination of trace rhodium based on the catalytic effect of Rh on the oxidative color reaction of diantipyry1-(p-dimethylamino)-phenylmethane (DAMAM) with potassium periodate in the H3PO4 medium and ot wateer bath was estabished. The optimum condition and kinetic parameters of this reaction were studied in detail. The linear range of the determination was 0～80μg/L, and the detection limit was 6.20×10-7g/L. The apparent activation energy og catalytic reaction was found to be 89.03kJ/mol, rate constant was 2.51×10-4/s. The system wasstable at least 6h. The method has been applid to determine trace rhodium in some catalyst samples with the relative standard deviation of 2.7%～3.2%(n=6) and recovery of 98.2%～103.2% (n=5).

OBJECTIVE:To provide reference for the establishment of prevention and control measures for medication errors. METHODS:Based on JCI standard,51 cases of medication error reported by ADE information platform of our hospital in 2012 were summarized,and analyzed in terms of error type,error time,working life of responsible person,etc. The prevention and con-trol strategies were introduced. RESULTS:Referring to related requirements of JCI standard,medication errors reduced significant-ly during 2013-2014 through personnel training and education,system improvement and process optimization. CONCLUSIONS:Medication errors surveillance and control is important for the promotion of rational use of drugs. JCI standard has played an impor-tant role in monitoring and preventing medication errors.

The catalytic effect of ruthenium on the oxidation reacti on of methylene blue (MB) was investigated and applied for the determination of ruthenium(Ⅲ) by the kinetic spectrophotometry in the sulfuric acid medium at 90±0.5℃. The optimum reaction conditions, kinetic parameters and r eaction mechan ism were studied. The linear ranges for the determination of ruthenium (Ⅲ) were 0.0～1.2 and 1.2～5.6 μg/L with a detection limit of 0.05 μg/L . Almost no foreign ions more than 50-fold concentration of Ru(Ⅲ) I nterfered with the determination. The method, which was of high sensitivity, good selectivity and stability, was s uccessfully applied for the determination of trace ruthenium in some ores and m e tallurgical products, the RSD (n=8) was 1.3%～2．2％ and the recovery was between 99% and 105%.

To summarize the causes of relocation stress in family members of patients transferred from ICU.Based on muhidisciplinary collaboration,stress prevention before transfer and stress intervention after transfer were implemented.For thirty family members of patients in our group,their level of relocation stress 7d after transfer was low.

Objective: To evaluate the long term efficacy of treating the primary dysmenorrhea of cold-damp stagnation type by Acupuncture of Liji therapy. Methods: In this study, a total of 76 cases of primary dysmenorrhea of cold-damp coagulation type were randomly divided into the acupuncture of Liji therapy group, and the body acupuncture group, with38 cases in each group. Both groups were continuously treated 3 menstrual cycles, and followed up in the third and six menstrual cycles after the end of the treatment. Visual analogue scale for abdominal pain and Dysmenorrhea Symptoms scale were used as therapeutic indexes. Remove shedding cases, the long-term effects and scores of the 2 groups were compared. Besides, untoward and side effects needed to be recorded. Results: There were 2 cases lost in the acupuncture ofLiji therapy group and 1 cases in the body acupuncture group. After treatment, The clinical comprehensive efficacy of acupuncture ofLiji therapy group was better than that of body acupuncture group (P ＜ 0. 05) . Both groups of VAS scores and dysmenorrhea symptom scores were decreased to different degrees during treatment and follow-up period (P ＜ 0.05) .The follow-up data of the body acupuncture group after six menstrual cycles were higher than that of the third menstrual cycles after treatment. Compared with the two groups, the acupuncture of Liji therapy group was superior to the body acupuncture group during the third menstrual cycles follow-up (P ＜ 0.05) and six menstrual cycles follow-up (P ＜ 0.01) .The treatment satisfaction of acupuncture of Liji therapy and body acupuncture was 91.67％ and 72.97％. There were no adverse reactions in the two groups during the study period. Conclusion: Acupuncture of Liji therapy can effectively relieve dysmenorrhea symptoms and the general discomfort caused by dysmenorrhea, the long-term effect is stable and durable. primary dysmenorrhea of cold-damp stagnation type with acupuncture of Liji therapy has definitely long term curative effect. In addition, the treatment of patients with acupuncture of Liji therapy is more satisfactory, it is worthy of cilnlcal application.

ObjectiveTo investigate the status and influencing factors of medication adherence in patients with severe mental disorders in Zhengzhou， so as to provide references for the formulation of prevention and treatment measures for severe mental disorders. MethodsFrom March to June 2021， a stratified multistage cluster sampling method was applied to select 342 patients from the National Information System for Severe Mental Disorders in Zhengzhou. The general demographic data of patients were collected via self-designed questionnaire， and the medication status was investigated， then the influential factors were summarized. The differences in influential factors of medication adherence were compared between the medication adherence group and the medication non-adherence group. Thereafter， Logistic regression analysis was applied to explore the factors influencing medication adherence. ResultsA total of 320 patients were included in the final analysis， altogether 76.56% of patients （n=245） complied with medication. The differences between patients in the medication adherence group and those in the medication non-adherence group were statistically significant in terms of residence， occupation， and outpatient chronic disease reimbursement （χ²=14.015， 7.502， 13.106， P<0.05 or 0.01）. In the questionnaire of influential factors on medication adherence， there were statistically significant differences in the scores of lack of insight， stigma and drug-related factors between the two groups （Z=7.588， 2.379， 2.893， P<0.05 or 0.01）. Outpatient chronic disease reimbursement was a protective factor for medication adherence （OR=2.727， 95% CI： 1.320~5.634， P<0.01）， while rural residence （OR=0.465， 95% CI： 0.221~0.977， P<0.05） and lack of insight （OR=0.398， 95% CI： 0.286~0.553， P<0.01） were risk factors for medication adherence. ConclusionPatients with severe mental disorders in Zhengzhou have a high rate of medication adherence， moreover， the outpatient chronic disease reimbursement， lack of insight and residence may be influencing factors for medication adherence in patients with severe mental disorders.
