Objective To investigate the effects of volatile oils of Rhizoma Acori Tatarinowii (RAT), Semen Myristicae (SM) and Pericarpium Citri Reticulatae (PCR) on percutaneous penetration of total alkali of Shortstalk Monkshood Root through mouse skin in vitro. Methods By using an improved Franz diffusion cells, the effects of these 3 kinds of volatile oil on the percutaneous penetration of total alkali of Shortstalk Monkshood Root were observed and compared with Azone, and the cumulative amount of Bullatine A was determined by HPLC. Results 7% (v/v) volatile oil RTA and SM, 5% (v/v) volatile oil of PCR and 3% (v/v) Azone were best concentration, the penetration coefficient were 5.88, 6.91, 5.30, 5.75, respectively. Compared with the group without penetration enhencers, the enhancement ratios were 1.09,1.28, 0.98, 1.06, respectively. Conclusion The volatile oil of RAT and SM enhance penetration of total alkali of Shortstalk Monkshood Root. The volatile oil of PCR cannot enhance penetration.

Objective:
To investigate the status and influencing factors of substance-induced psychotic disorders in residents over 18 years old in Hebei Province, and to provide evidence for the prevention and control of substance-induced psychotic disorders.
Methods:
Using multi-stage stratified random sampling method, the permanent residents aged 18 years and over were selected from urban and rural areas in Hebei Province. The demographic data was collected, the 12-Item General Health Questionnaire ( GHQ-12 ) and eight risk factors about mental disorder questionnaire were used to find out mental disorders. The multivariate logistic regression model was conducted to analyze the influencing factor for substance-induced psychotic disorders.
Results:
A total of 23 675 questionnaires were sent out, 20 884 were valid ( 88.20% ).The weighted lifetime prevalence rates of substance-induced psychotic disorders, alcohol-related disorders, sedatives/hypnotics/anti-anxiety disorders and other substance-induced psychotic disorders were 6.20%, 5.93%, 0.24% and 0.04%, respectively. Multivariate logistic regression analysis showed that age ( 35-<45, OR=1.582, 95%CI: 1.091-2.292; 45-<60, OR=2.185, 95%CI: 1.524-3.132; ≥60, OR=2.061, 95%CI: 1.422-2.986 ), males ( OR=10.832, 95%CI: 8.265-14.196 ), urban area (OR=1.431, 95%CI: 1.202-1.703 ), non-poor family ( OR=2.291, 95%CI: 1.652-3.177 ), physical diseases ( OR=2.028, 95%CI: 1.678-2.452 ) and genetic history ( OR=1.574, 95%CI:1.181-2.098 ) were the influencing factors for substance-induced psychotic disorders.
Conclusion
The lifetime prevalence of substance-induced psychotic disorders among residents aged 18 years and over in Hebei Province is 6.20%, which is mainly related to age, gender, region, family economic situation, physical disease history and genetic history.

OBJECTIVE:To provide reference for rational use of antipsychotic drugs in schizophrenia patients. METHODS:The general information and antipsychotic treatment information,which were extracted from the database of prior drug investigation in Mental Health Center of Hebei Province in 2002,2006 and investigation data in 2012 of 5014 schizophrenia patients,were ana-lyzed. RESULTS:Over time,the frequency of the first generation antipsychotic drugs decreased(P<0.05),while that of the sec-ond generation antipsychotic drugs increased (P<0.01). The frequency of long-acting antipsychotic drugs were generally low among outpatients and inpatients in 2002,2006,2012,with statistical significance(P<0.01). There were no significant difference in the proportion of outpatients receiving antipsychotic drugs combination treatment and monotherapy (P>0.05). Over time,the proportion of inpatients receiving monotherapy decreased,while that of inpatients receiving combination treatment increased (χ2=18.682,P<0.01). CONCLUSIONS:The second generation antipsychotic drugs have gradually replaced the first generation antipsy-chotic drugs,and have became the leading drugs in the treatment of schizophrenia in Hebei province. The proportion of inpatients receiving combination treatment has increased,which is different from the domestic and foreign prevention and treatment guide-lines.

Objective To compare the differences of prescription pattern, adverse events, economic burden and drug-use adherence between preferred mood stabilizers and preferred antipsychotics in patients with bipolar disorder. Methods We investigated 240 cases of patients with bipolar disorder from 39 mental health institutions in 11 cities in Hebei province. The self-made questionnaire was used to investigate the demographic information, disease characteris-tics, prescription pattern and medical expense. The clinical global impression scale-severity of illness (CGI-SI) was used to assess the disease severity. The treatment emergent symptom scale (TESS) was used to assess the adverse drug reac-tions. The medication adherence rating scale (MARS) was used to assess drug therapy compliance in patients. Results One hundred fifty-two patients (63.3%) used antipsychotics as the first choice (antipsychotics group), 88 patients (36.7%) used mood stabilizers as the first choice (mood stabilizers group). The number of patients in-patient (90.1%vs. 76.1%), patients with psychotic symptom (27.0%vs. 11.4%), incidences of adverse events (46.1%vs. 31.8%), drug daily cost (me-dians 12.00 yuan vs. 8.37 yuan) and drug total cost (medians 344.61 yuan vs. 144.64 yuan) were larger in antipsychotics group than in mood stabilizers group (P<0.05). There was no significant difference between two groups in pattern of pre-scription, severity of adverse events and total scores of MARS (P>0.05). Conclusion The bipolar disorder patients more frequently use antipsychotics as the first choice in Hebei province. The use of antipsychotics does not alter the combina-tion medication pattern. In addition, antipsychotics cause a higher incidence of adverse events and heavier economic bur-den compared with mood stabilizers, suggesting that mood stabilizers should be the first choice to bipolar disorder.
