RESUMO
Insect-induced plant volatile organic compounds (VOCs) may function as either direct defence molecules to deter insects or indirect defence signals to attract the natural enemies of the invading insects. Tea (Camellia sinensis L.), an important leaf-based beverage crop, is mainly infested by Ectropis obliqua which causes the most serious damage. Here, we report a mechanistic investigation of tea plant-derived VOCs in an indirect defence mechanism against E. obliqua. Parasitoid wasp Parapanteles hyposidrae, a natural enemy of E. obliqua, showed strong electrophysiological response and selection behaviour towards S-linalool and ß-ocimene, two monoterpenes with elevated emission from E. obliqua-damaged tea plants. Larvae frass of E. obliqua, which also released S-linalool and ß-ocimene, was found to attract both mated female or male Pa. hyposidrae according to gas chromatography-electroantennogram detection and Y-tube olfactometer assays. In a field setting, both S-linalool and ß-ocimene were effective in recruiting both female and male Pa. hyposidrae wasps. To understand the molecular mechanism of monoterpenes-mediated indirect defence in tea plants, two novel monoterpene synthase genes, CsLIS and CsOCS-SCZ, involved in the biosynthesis of S-linalool or ß-ocimene, respectively, were identified and biochemically characterised. When the expression of these two genes in tea plants was inhibited by antisense oligodeoxynucleotide, both volatile emission and attraction of wasps were reduced. Furthermore, gene expression analysis suggested that the expression of CsLIS and CsOCS-SCZ is regulated by the jasmonic acid signalling pathway in the tea plant.

OBJECTIVE: To create civil capacity rating scale for mentally disabled patients, and explore its feasibility during the forensic psychiatric expertise. METHODS: The civil capacity-related items were determined after discussion and consultation. The civil capacity rating scale for mentally disabled patients was established and the manual was created according to the logistic sequence of the assessment. The rating scale was used during the civil assessment in four institutes. RESULTS: There were 14 items in civil capacity rating scale for mentally disabled patients. Two hundred and two subjects were recruited and divided into three groups according to the experts' opinion on their civil capacities: full civil capacity, partial civil capacity and no civil capacity. The mean score of the three groups were 2.32 +/- 2.45, 11.62 +/- 4.01 and 25.02 +/- 3.90, respectively, and there was statistical differences among the groups. The Cronbach alpha of the rating scale was 0.9724, and during the split-reliability test, the two-splited part of the rating scale were highly correlated (r = 0.9729, P = 0.000). The Spearman correlative coefficient between each item and the score of the rating scale was from 0.643 to 0.882 (P = 0.000). There was good correlation between the conclusion according to the rating scale and the experts' opinion (kappa = 0.841, P = 0.000). When the discriminate analysis was used, 7 items were included into the discrimination equation, and 92.6% subjects were identified as the correct groups using the equation. CONCLUSION: There is satisfied reliability and validity on civil capacity rating scale for mentally disabled patients. The rating scale can be used as effective tools to grade their civil capacity during the forensic expertise.

OBJECTIVE: To determine the best time for assessing mental disability due to brain damage. METHODS: Ninety-three mental disabilities due to brain damage in traffic accidents were assessed and their follow-up studies were taken in different period after the brain injury: 3 months, 6 months, 9 months and 12 months. The patients' brain imaging, electroencephalogram (EEG) and detailed medical history were collected. Then to interview the patients' family members and to assess the patients' mental conditions with Wechsler Adult Intelligence Scale (WAIS), Social Disability Screening Schedule (SDSS), and Activity of Daily Living Scale (ADL). Diagnosis and disability assessments were based on all of the above information. RESULTS: ADL and SDSS had good distinction between different levels of disability and different time. The overall sample demonstrated that there was no statistically significant difference between patients' ADL and SDSS averages in 9 and 12 months. For mild disability, there was no statistically significant difference between ADL and SDSS averages in 6, 9 and 12 months. For moderate disability, there was no statistically significant difference between ADL and SDSS in 9 and 12 months. And there was no statistically significant difference between ADL and SDSS averages in 6, 9 and 12 months for severe disability. CONCLUSION: For mild disability, it is recommended to assess the mental disability 6 months after the injury, for moderate disability, it is 9 months. The statistics data recommended that the best assessment time for severe disability is 6 months after injury. However, our comprehensive analysis concludes that the suitable time is 9 months after injury.

Testamentary capacity is one of the civil competences, it means that a natural person enjoys the capacity or qualification to establish testament and deal with his property. Recently, the cases of testamentary capacity assessment of the mentally disordered are increasing. This article firstly introduces the concepts of the testament as well as the testamentary capacity, and then summarizes the assessment standard of the testamentary capacity, by using the Banks v. Goodfellow case as a basis to make the standard criteria including: the understanding of the nature of a will and codicil, the knowledge of the general extent of one's assets, the knowledge of the natural object of one's bounty, the understanding of the impact of the distribution of the assets of the estate, and the absence of a delusion specifically affecting the distribution of the estate. The impact factors of the testamentary capacity, including dementia, mood disorder, schizophrenia, alcohol, drug, and undue influence, etc., are summarized. Lastly, the related assessment tools such as the Mini-Mental State Examination, the Clock-Drawing Test, and the Testament Definition Scale are introduced briefly.

In China, the criminal responsibility of the mentally disordered offenders is divided into three levels, there are the whole responsibility, diminished responsibility and irresponsibility. According to the Criminal Law, "If a mental disordered patient causes harmful consequences at a time when he is unable to recognize or control his own conduct, upon verification and confirmation through legal procedure, he shall not bear criminal responsibility." That means there are two standards of assessing criminal responsibility, namely volitional and cognitive capacity. It is as equal as the Mc'Naughton Rule and the Irresistible Impulse Test. But for a long time, the criminal responsibility was assessed mainly by experience because of lacking of standardized assessment instrument. Recently, we have developed "the rating scale of criminal responsibility for mentally disordered offenders (RSCRs)". The scale includes eighteen items, namely criminal motivation, aura before offense, inducement of crime, time and place and object and tool selectivity of crime, emotion during the crime, shirking responsibility after offense, concealing the truth during inquest, camouflage, understanding the nature of the offense, estimating the consequence of the offense, impairment of life ability, impairment of learning or work, impairment of insight, impairment of reality testing, and impairment of self-control. This scale can be applicable for all cases and easy to use. This scale had been tried out in several forensic psychiatry institutes, the Cronbach α of the scale is 0.93, and all items have high correlation with the total score of the scale (r=0.50-0.89). Two factors were extracted by the factorial analysis, and the cumulative squared loading was 68.62%. The scores of the three levels were 9.66 ± 5.11, 26.54 ± 5.21 and 40.08 ± 7.90 respectively and highly significant differences were observed among groups. By establishing discrimination analysis among three levels, classification results suggested that 88.90% of the original grouped cases were correctly classified, and the discriminant value had high conformity with the experts' opinions. The data showed that the scale would be the best validated instrument for the criminal responsibility in China.
