Objective To exam the personality traits and self-concept of school phobia patients with different academic achievements.Methods 38 school phobia patients with high academic achievement and 19 school phobia patients with low academic achievement were assessed with Eysenck' s personality questionnaire and Piers-Harris Children' s Self-concept Scale.Results High academic achievement group of psychoticism and neuroticism higher than that of low academic achievement group.High academic achievement group of Self-concept's total scores,behavior,intelligence and the school situation higher than that of low academic achievement group.High academic achievement group of anxiety scale score lower than that of low academic achievement group.The personality traits of school phobia correlated with the self-concept on some level.Conclusion Different academic achievements of school phobia patients have different personality traits and have different self-concept,so they need to individualized treatment options.

Objective To evaluate the quality of life of patients with diabetes mellitus in rural areas,and to analyze the main influencing factors.Methods The EQ -5D and questionnaire were used to collect information of patients with diabetes mellitus and to evaluate their quality of life.Logistic regression,multiple liner regression analyses and other statistical methods were used to analyze the related factors of life quality among rural patients with diabetes mellitus. Results A total of 416 patients with diabetes mellitus were investigated.The mean score of EQ -5D and EQ -VAS of all cases were 0.835 ±0.197 and 61.48 ±16.47 respectively,and the rates of the participants had problems at the dimensions of mobility,self -care,usual activities,pain/discomfort and anxiety/depression were 21.15%,11.54%,17.31%, 38.46% and 47.12% respectively.Logistic regressions for the five dimensions showed that complications were the common significant factors of all five dimensions,and age was related to the dimensions of mobility,usual activities,pain/discomfort and anxiety/depression.Gender and HbA1C were influencing factors of pain/discomfort dimension.Multiple liner regression analyses showed that the number of complications was the influencing factors of the valuation of EQ -5D and the score of EQ -VAS.Conclusion The quality of life among patients with diabetes mellitus in rural areas was lower than healthy people.Anxiety/depression was the most common problem,and complications were the main factor for the decrease of quality of life among diabetic patients.

According to the transcriptome dataset of Panax notoginseng, the key geranylgeranyl pyrophosphate synthase gene (GGPPS) in terpenoid backbone biosynthesis was selected to be cloned. Using specific primer pairs combining with RACE (rapid amplification of cDNA ends) technique, the full-length cDNA sequence with 1 203 bp, which containing a 1 035 bp open reading frame, was cloned and named as PnGGPPS. The corresponding full-length DNA sequence contained 2 370 bp, consisted of 1 intron and 2 exons. The deduced protein PnGGPPS contained 344 amino acids and shared more than 73% identity with GGPPS from Ricinus communis and Salvia miltiorrhiza. PnGGPPS also had specific Aspartic acid enrichment regions and other conserved domains, which belonged to the Isoprenoid-Biosyn-C1 superfamily. The quantitative real-time PCR showed that PnGGPPS expressed in different tissues of 1, 2, 3 years old root, stem, leaf and 3 years old flower, and the expression level in 3 years old leaf was significant higher than that in other organs, which suggested that it might not only be involved in the regulation of the growth and development, but also be associated with the biosynthesis of chlorophyll and carotenoids, the development of chloroplast, the shade habit and the quality formation of P. notoginseng.

OBJECTIVETo verify the pharmacological hypothesis of prescriptions by studying the targeted distribution of major components in stewed rhubarb in the rat model with acute pancreatitis (AP).

METHODNormal SD rats (control group, n = 5) and the AP model induced with intraperitoneal cerulein (model group, n = 5) were taken as the experimental objects. Rats of the two groups were orally administered with stewed rhubarb granules (20 g x kg(-1)). Their heart, liver, spleen, lung, kidney and pancreas were collected two hours after the administration. Such constituents as emodin, chrysophanol, physcion, rhein and aloe-emodin and their concentrations in each tissue homogenate were detected by high performance liquid chromatography-mass-mass.

RESULTAloe-emodin and physcion in stewed rhubarb whose concentrations in liver and kidney of normal rats were higher than that in pancreatic tissues, while the distribution spectrums and concentrations of the remaining components in pancreatic tissues had no significant difference with that of other organs. The concentrations of emodin, aloe-emodin, rhein and chrysophanol in stewed rhubarb in pancreatic tissues of the AP model group were higher than that in other tissues and organs, while their concentrations in pancreatic, renal and splenic tissues were notably higher than that in the normal group.

CONCLUSIONIn the conditions of AP, effective components in stewed rhubarb show a targeted distribution feature in pancreas, which provides experimental basis for the pharmacological hypothesis of prescriptions.

Chemical constituents of Inula japonica were isolated and purified by repeated column chromatographies, over silica gel, and Toyopearl HW-40, and preparative HPLC. On the basis of spectral data analysis, including NMR and MS data, the structures of the isolates were elucidated and their anti-inflammatory activities were assayed. Fifteen compounds were isolated from the ethyl acetate extract of I. japonica, and their structures were elucidated as dihydrosyringenin (1), (3S, 5R, 6S, 7E)-5,6-epoxy-3-hydroxy-7-megastigmen-9-one (2), (6R, 7E) -9-hydroxy-4,7-megastigmadien-3-one (3), arnidiol (4), taraxasterol acetate (5), 8,9,10-trihydroxythymol (6), taxifolin (7), luteolin (8), napetin (9), eupatin (10), spinacetin (11), quercetin (12), p-hydroxycinnamic acid (13), caffeic acid (14), and caffeoyl acetate (15). Compounds 1, 2, 7, 13 and 15 were isolated from the genus Inula for the first time, and compounds 3, 4, 9-11 and 14 were isolated from this plant for the first time. The anti-inflammatory activity result showed that compounds 3, 6-12 and 14 exhibited inhibition effect against leukotriene C4 (LTC4) synthesis and degranulation definitely in c-Kit Ligand (KL) induced mast cells, and compound 8 and 12 also had the suppression effect against lipopolysacharide(LPS) induced nitric oxide (NO) activity in RAW264.7 macrophages. It is firstly reported that compounds 7 and 9-11 possessed potent inhibition activities against LTC4 generation and degranulation in mast cells.
