Objective To establish a rapid surface-enhanced Raman spectroscopy(SERS)method for detection of five banned benzodiazepines in blood,including alprazolam,nitrovalam,Temazepam,diazepam and cloazepine.Methods Ethanol was used as extraction agent to extract nitrodiazepam,nitrazepam,diazepam and clonazepam from blood,a mixture of PSA and C18 was added for optimization,and SERS technology was used for detection.Results Experiments showed that nitalprazolam,nitrodiazepam,Temazepam,diazepam and chlorazepine all had corresponding Raman characteristic signal peaks,which could be used as the basis for qualitative discrimination.The detection limits of these benzodiazepines in blood were between 0.5 and 1 μg/mL.Conclusion This method is simple to operate and has a fast analysis speed.It is suitable for the rapid detection of drugs in blood samples.

Objective:To explore the effect of hand making combined with social skills training on the self-care ability and quality of life of patients with schizophrenia.Methods:According to random number table method, totally 120 patients with schizophrenia admitted to the Second People ′s Hospital of Chuzhou City, Anhui Province from January to December 2019 were divided into observation and control groups, which had 60 patients in each groups, 10 cases and 7 cases fell off respectively. The control group received antipsychotic medication and routine nursing, meanwhile the general recreational activities (circles, radio exercises, etc.) and physical therapy were also carried out in the department and rehabilitation physical therapy center. The observation group was given hand making and social skills training for 12 weeks on the basis of the control group. The self-care ability and quality of life of patients in the two groups were compared before intervention, 6 and 12 weeks after intervention. Results:Before intervention, there was no statistical significance in the scores of World Health Organization Quality of Life Scale (WHOQOL-BREF) and Activities of Daily Living (ADL) in 2 groups ( P>0.05). After 6 and 12 weeks of intervention, ADL scores in the observation group were (96.40±3.79) and (98.50±2.53) points, while those in the control group were (93.96±4.31) and (94.06±4.28) points. And the difference between the two groups was statistically significant ( t values were 3.38, 6.36, P<0.05). However, after 6 weeks of intervention, there was no significant difference in WHOQOL-BREF scores between the two groups ( P>0.05); after 12 weeks of intervention, the scores of WHOQOL-BREF in the domains of G1(patients′ self-rated quality of life), G4(patients′ satisfaction with self-rated health status), physiology, psychology, social relations and environment in the observation group were (3.76±1.14), (3.86±1.03), (14.83±2.56), (15.04±3.07), (14.72±3.67) (14.55±3.22) points. The scores of the control group were (3.00±0.83), (3.34±0.90), (12.79±2.06), (12.70±2.45), (12.70±3.06) and (12.64±2.42) points. And the difference between the two groups was statistically significant ( t values were from 2.73 to 4.47, P<0.01). Conclusions:Hand making combined with social skills training can improve the self-care ability and quality of life of patients with schizophrenia, and it is an effective means of treatment to help the patients with schizophrenia to achieve recovery, out of the hospital, back to society.
