Objective to investigate the emotional state and childhood trauma among users of amphetaminetype-stimulants under compulsory seclusion rehabilitation in Shaoxing.Methods A cross-sectional design was conducted on 140 users of ATS in Shaoxing compulsory isolation drug rehabilitation center,collecting general information using homemade questionnaires.Using the Patient Health Questionnaire (PHQ-9),Generalized Anxiety Disorder Scale (GAD-7) and Mood Disorder Questionnaire(MDQ) to investigate the emotional state of users of ATS.The Childhood Trauma Questionnaire (CTQ) was applied to explore the childhood trauma experiences of users of ATS.Results Among the 140 users of ATS,84 (60％) users had emotional problems,24 users (17.14％) of anxiety disorder,22 users (15.72％) of depression,27 users (19.28％) of depression and anxiety disorder.66 users (47.1％)experienced at least one childhood trauma.The most common childhood trauma is the physical neglect,60 users (42.9％),followed by emotional neglect in 23 users(16.4％),again sexual abuse in 18 users (12.9％),emotional abuse and physical abuse is relatively fewer.Conclusion Among users of ATS under compulsory seclusion rehabilitation,emotional problems is prevalent.Proper emotional intervention and treatment in users of ATS would promote their mental health,thereby reducing the re-use of ATS,better return to society life.

Early life stress and schizophrenia:a retrospective case-control study / 中华全科医师杂志

A total of 105 patients with first-episode schizophrenia (male =51,female =54) and 99 normal controls (male =51,female =48) were included into this retrospective case-control study.Childhood trauma questionnaire-28 item short form (CTQ-SF) was used to assess the experience of childhood abuse.The result of binary logistic regression showed that emotional abuse (β =0.630,P ＜ 0.05) and emotional neglect(β =0.270,P ＜ 0.05) were included into the final model of predicting schizophrenia.It indicates that patients with first-episode schizophrenia experienced more early life stress than controls.Particularly emotional abuse and emotional neglect may play important roles in the onset of schizophrenia.

Study on Chemical Constituents of Citrus mediea var. sarcodactylis from Sichuan Province (Ⅱ) / 中药新药与临床药理

Objective To investigate the chemical constituents of Citrus medica var. sareodactylis from Sichuan province, and to provide evidence for the development and utilization and quality evaluation of the medicinal material.Methods Various chromatographic techniques were used to purify the components of this herb. Compounds were identi-fied by their physical characteristics and spectral feature. Results Seven compounds were isolated from Citrus medica var. sarcodactylis, and they were identified as sibiricol (Ⅵ), 7-methylesculetin (Ⅶ), bergapten (Ⅷ), sigmasteryl acetate(Ⅸ), 5-methoxyfurfural(Ⅹ), limonin(Ⅺ), daucosterol (Ⅻ). Conclusion Compound Ⅵ, Ⅶ and Ⅸ are isolated from plants of Rutaceae for the first time.

Determination of Lasiokaurin in the Stems and Leaves of Rabdosia nervosa by HPLC / 广州中医药大学学报

Objective To develop a HPLC method for the determination of Lasiokaurin in the stems and leaves of Rabdosia nervosa.Methods HPLC was performed on a Kromsil C18 reversed-phase column(250mm?4.2mm,5?m).All of the reference substances and samples were separated with the mobile phase of methanol :water(55:45) under isocratic elution for 30min,flow rate was 1.0ml/min,the detection wavelength was 234nm,and the column temperature was 30℃.Results The content of Lasiokaurin was 0.005mg/g in the stems and 0.372mg/g in the leaves,the content in the stems were almost 1/75 times as much as that in the leaves.The average recovery of Lasiokaurin was 96.21%.Conclusion This developed method,which is simple and with good precision,high sensitivity and selectivity,can be used for quality evaluation of Lasiokaurin in Rabdosia nervosa.

Determination of Oridonin in Rabdosia nervosa by HPLC / 中药新药与临床药理

Objective To develop a HPLC method for the determination of oridonin in the leaves and stems of Rabdosia nervosa.Methods All of reference substances and samples were separated with the mobile phase of methanol:water (45 ∶55) under isocratic elution for 20 min on a Kromasil C18 reversed-phase column(250 mm?4.0 mm,5 ?m),the flow rate was 1.0 mL?min-1,the detection wavelength was 235 nm,and the column temperature was 30 ℃.Results The content of oridonin was 0.047 mg/g in stems and 0.791 mg/g in leaves,the content in stems being about one seventeenth of that in leaves.The average recovery of oridonin was 98.33 %.Conclusion This method is simple,sensitive,accurate and suitable for quantitative determination of oridonin in Rabdosia nervosa.

Fingerprints of Fructus Citri Sarcodactylis from Guangdong by HPLC / 中草药

Objective To establish the HPLC fingerprints(HPLC-FPS)of Fructus Citri Sarcodactylis(FCS)from Guangdong for reflecting the internal chemical information,evaluating its internal quality of FCS and identifying them from different cultural areas.Methods The HPLC-FPS of 12 FCS samples were obtained.The HPLC separation was performed on a Kromasil C18 analytical column by gradient eluting with acetonitrile-0.5% acetic acid at the flow rate of 1.0 mL/min.The column temperature was 30 ℃,the UV detection wavelength was 290 nm,and the collection time was 75 min.Results The mutual mode of HPLC fingerprints was set up and the similar degrees to the crude drugs from different cultural areas were compared.Conclusion The method is stable,reliable,and with full information which can be used as a quality control item for FCS from Guangdong.
