The volatile oil is the main component in the leaves of Perilla frutescens. According to the main types of monoterpenoids or aromatic compounds, it can be divided into different chemotypes and the main chemotypes of Chinese producing Perilla are PA type (mainly containing Perilla aldehyde and limonene), PK type (mainly containing perillaketone) and PP type (subdivided as PP-a type, with apiole as its main component; PP-m type, with myristicin as its main component; PP-e type, with elemicin as main component; PP-as type, with asarone as main component). Based on the biosynthetic pathways analysis, we also found that the formation of the particular chemotype is usually controlled by a single gene or a few genes, and different types have different pharmacological effects. In this paper, the classification under the species P. frutescens, main chemotypes of the volatile oil, and their biogenesis and regulation, pharmacological effect and influence factors are summarized and reviewed.

Objective To evaluate the influence and safety of topical ketamine on postoperative sore throat following endotracheal intubation. Methods The clinical literatures concerning topical application of ketamine for the prevention of postoperative sore throat (POST) were searched from online databases. Randomized controlled trials were selected by the inclusive and exclusive criteria. Meta-analysis was conducted to assess the risk ratio(RR) of the incidence of POST and software Stata 12.0 was used in this analysis. Results Seven randomized trials involving 490 patients were included in this meta-analysis. The results of meta-analysis showed that the incidence of POST was significantly reduced in the ketamine group,with RR 0.61(95%CI 0.47~0.79,P<0.001) at 0~1 h,0.55(95%CI 0.43~0.71, P<0.001) at 4 h and 0.48 (95%CI 0.34 to 0.66, P<0.001) at 24 h after surgery. No major complications related to topical ketamine were observed. Conclusions For the patients receiving general anesthesia and endotracheal intubation, topical prophylactic application of ketamine can significantly reduce the incidence of POST without major complications.

Objective To explore the effects of peripheral stem cell transplantation on extremely severe bone marrow form of acute radiation sickness.Methods One patient was radiated aecidently with the radiation dosage of 9～15 Gy and diagnosed as extremely severe bone marrow form of acute radiation sickness.Pretreatment was performed at 4th day after the accident and 3 days later,HLA- matched allogeneic stem cell transplantation on the patient was performed.Graft versus host disease (GVHD) was prevented with cyclosporin A (CsA) and mycophenolate mofetil (MMF).Results The haematopoiesis was recovered at 9th day after transplantation.At 11th day after transplantation, WBCs were increased to 14.74?10~9/L and returned to the normal levels subsequently,number of platelets risen to 51?10~9/L and hemaglobin was over 80 g/L.TRS-PCR and blood type dynamic detection testified that the donor's cells were stably implanted,the chromosome aberration and micro- nuclei disappeared after transplantation,and the patient's blood type changed into the donor's at 27th day after transplantation.But the radiation injury were still getting worse complicated with multiple infections,At 68th day after transplantation (75 days after the accident),the patient was died of mul- tiple organs failure.Conclusion Extremely severe bone marrow form of ARS can achieve hematopoie- sis recovery by allogeneic stem cell transplantation,but only hematopoiesis recovery can not cure the immunodefficiency and the radiation injury of the whole body.

Objective To explore the personality characteristics of abused children in order to reduce the incidence of child abuse.Methods Two hundred and ninty five middle school students were investigated with general questionnaire and Eysenck Personality Questionnaire of children. Eighty six students experiencing child abuse (CA) last year as study group and one hundred and ninety six non-abuse children as controls (NCA) were analyzed by means of Eysenck Personality Questionnaire of children.Results The score of neuroticism in CA group was significantly higher than that in the control group (55.62±10.60/52.65±10.98,t=-2.114 P=0.035). The score of lie in CA group was significantly lower than that in control group (42.21±9.87/46.04±9.20,t=3.184 P=0.002). On the impact of different sex, the psychoticism score of male was significantly higher than that in the control group(52.37±11.49/48.04±9.97,t=-2.227 P=0.028), and the lie score was significantly lower than that in control group(41.03±9.18/46.18±8.79,t=3.125 P=0.002).The scores of those in the female were not significant.Conclusions There is a close association between the unstable emotion and child abuse in children, so training emotional self-control and emotional expression of children might be a intervention strategy in the future. In addition, the frequency of lie in children is probably one of factors that determine whether children are abused or not.

Measuring the content of soluble reducing sugar, total sugar, soluble protein, guanosine, alkaloids, and succinic acid of Pinellia ternata tuber were measured by anthrone-sulfuric acid colorimetric method, Coomassie brilliant blue method, RP-HPLC, reverse potentiometric titration, acid dye colorimetry, respectively. The result showed that yellow light could promote the growth and development of P. ternata and increase the content of soluble reducing sugar, total sugar, alkaloids, and succinic acid. Under blue light could promote the content of soluble protein and guanosine. Red and yellow light increased the content of chlorophyll a and chlorophyll b, contrastively blue light reduced the content of chlorophyll a and chlorophyll b. White film through the most uniform spectrum was most conducive to the synthesis of chlorophyll a. As single film, blue film, yellow film were more conducive to the synthesis of chlorophyll a, green film and red film had been relatively beneficial to the synthesis of chlorophyll b. Bulbil formed the largest number and the biggest propagation coefficient of P. ternata under red light showed that it could increase the production of P. ternata under red light.

Nitrobenzene is one of the toxic compounds. Much work had focused on biodegradation of it sofar. Two main pathways for nitrobenzene biodegradation, oxidative and partial reductive pathways, were reviewed in this article. The mechanism of these pathways including involved enzymes and genes was introduce in details. Comparative analysis of the pathways would provide basis for the development and application of biodegradation technology for nitrobenzene and other organic pollutants.

In order to optimize the testing methods for Paeonia suffruticosa seed quality, and provide basis for establishing seed testing rules and seed quality standard of P. suffruticosa. The seed quality of P. suffruticosa from different producing areas was measured based on the related seed testing regulations. The seed testing methods for quality items of P. suffruticosa was established preliminarily. The samples weight of P. suffruticosa was at least 7 000 g for purity analysis and was at least 700 g for test. The phenotypic observation and size measurement were used for authenticity testing. The 1 000-seed weight was determined by 100-seed method, and the water content was carried out by low temperature drying method (10 hours). After soaking in distilled water for 24 h, the seeds was treated with different temperature stratifications of day and night (25 degrees C/20 degrees C, day/night) in the dark for 60 d. After soaking in the liquor of GA3 300 mg x L(-1) for 24 h, the P. suffruticos seeds were cultured in wet sand at 15 degrees C for 12-60 days for germination testing. Seed viability was tested by TlC method.

Twelve populations of Inula lineariifolia were used as materials to measure morphological characteristics, photosynthetic parameters and chemical constituents. It aims to provide a theoretical basis for germplasm resources evaluation. The results showed that I. lineariifolia had relatively rich morphological diversity, there were significant differences of morphological characteristics, photosynthetic parameters and chemical constituents among populations. There was positive correlation on morphological characteristics and P(n). Twelve populations were divided into three-type. The three populations of Xuyi, Mingguang and Fengyang were of narrower-longer leaf, bigger biomass,better photosynthetic and higher chemical constituents. Then they were classified for a similar group. It proved that the three populations were more suitable for cultivation and promotion.
