OBJECTIVE: To study the stability of dexamethasone sodium phosphate(DSP) eye drops and predict its validity duration.METHODS: The content of DSP in eye drops was determined by HPLC and its validity duration was predi-cated using initial average rate method.RESULTS: The linear concentration range of DSP was 18～70 ?g?mL-1(r=0.999 9) with an average recovery rate of 99.74%(RSD=0.37%).The content of DSP in the eye drops decreased as its storing temperature increased and the storing time prolonged,but its pH was stable. The validity duration of the eye drops was computed to be 70 days at 25 ℃ and 438 days at 4 ℃.CONCLUSION: This eye drops were stable at 4 ℃.

This study was aimed to compare the pharmacokinetics (PK) of Shengmai injection and Shenmai injection with a single injection administration using a constant speed in subjects with stable angina pectoris.A total of 20 subjects with stable angina pectoris were divided into two groups.Each group was administered with Shengmai and Shenmai injection.The liquid chromatography-mass spectrometry (LC/MS) was adopted to determine concentrations of ginsenosides in plasma at different time points.PK parameters were calculated for comparison.The results showed that after a single intravenous infusion of Shengmai and Shenmai injection,the Cm.of ginsenoside Rg1,ginsenoside Re,ginsenoside Rb1 and ginsenoside Rc in Shenmai group were higher than those of the Shengmai group with statistical significance (P ≤0.05).There were differences on the T1/2 of ginsenoside Rg1,AUC0-144h and CL of ginsenoside Rc,as well as Tmax of ginsenoside Rd (P ≤ 0.05).However,there was no significant difference shown on other PK parameters.It was concluded that after a single Shengmai or Shenmai injection,there were PK differences of ginsenoside Rg1,ginsenoside Re,ginsenoside Rb1 and ginsenoside Rc in the human body.The clinical medication selection should be based on syndrome differentiation and treatment of patients.

ObjectiveTo explore the effect of synthesized rehabilitation on detoxification addicts.Methods100 detoxification addicts were randomly divided into the rehabilitation group and control group with 50 cases in each group. Cases of the rehabilitation group were treated with "ten-step" rehabilitation treatment, but that of the control group did not. The rehabilitating treatment included cognitive psychotherapy, behavioral therapy, family treatment, social skill training and etc. The effects of two groups were evaluate with Symptom Checklist-90 (SCL-90) scale.ResultsExcept hostility, other factorial scores of the rehabilitation group including positive items, somatization, obsession, interpersonal sensitivity, depression, phobia, paranoid and psychotic factors were significantly higher than that of the control group (P<0.05～0.01).ConclusionThe synthesized rehabilitation can obviously improve the psychology of detoxification addicts.

ObjectiveTo investigate the Character of Symptom Checklist 90 (SCL-90) in detoxification addicts in reeducation center.Methods100 detoxification addicts in reeducation center were evaluated.ResultsThe results showed that the mean scores of all factors in detoxification addicts were higher than those of normal population, and there was difference between different drug dependence addicts.ConclusionThe detoxification addicts shows serious psychological disorders.

Objective To discuss the evaluation basis of the clinical rational use of Dahuang Zhechong Capsule and to establish its rationality evaluation criterion to promote the sensible use of Dahuang Zhechong Capsule.Methods The rationality evaluation criterion for Dahuang Zhechong Capsule was formulated by referring to the package insert,treatment guidelines,and other literature.According to the criterion,270 outpatient prescriptions using Dahuang Zhechong Capsule in Xiyuan Hospital,China Academy of Chinese Medical Sciences were reviewed from January to June 2020.The indication,usage and dosage,drug combination,and repeated administration were analyzed.The pharmaceutical intervention was performed to address the problems found in the prescription reviews,and 328 outpatient prescriptions using Dahuang Zhechong Capsule in October 2020 were reevaluated.Results The irrational use rate of Dahuang Zhechong Capsule from January to June 2020 was 42.22％(114 cases),including 108(40％)cases of inappropriate indications,five(1.85％)cases of improper usage and dosage,and one(0.37％)case of inappropriate administration route.However,the pharmaceutical intervention in October 2020 remarkably reduced the irrational use rate of Dahuang Zhechong Capsule(4.27％,14 cases),all of which were inappropriate indications.Conclusion Dahuang Zhechong Capsule is being used irrationally;therefore,establishing an evaluation criterion is required.The specific situation of irrational drug use can be identified by prescription review according to its rationality evaluation criterion to manage its clinical use better and promote its rational use.
