Objective The kinetic house tree person test has many advantages compare to traditional psychometrics,but also some limits such as scoring subjectively and ambiguous.This research attempted to develop a reliable scoring system.That can distinguish college students with emotional disorder from normal college students by employing kinetic house tree person (KHTP) drawings.Methods 143 College students were invited to partake in the research KHTP drawings,the Beck Depression Inventory Ⅱ (BDI-Ⅱ),the Beck Anxiety Inventory (BAI) were administered to the subjects.Undergraduates with a BDI score of ≥ 14 or a BAI score of ≥8 were classified as the clinical group,while those with a BDI-Ⅱ and a BAI score are minimal were classified as the controis.The researcher and an expert studied and analyzed the KHTP drawings Manual,filtrate 35 indicators correlate to emotional disorder,and then researcher make standard for evaluation of every indicator.The standard for evaluation were then revised by the researcher and another rater then finalized by the expert.Results The results showed that 35 indicators correlate to emotional disorder were found,and there were significant differences in facial expressions (x2 =19.109,P<0.01) and actions (x2 =13.341,P< 0.01) between clinical group and normal group.The Pearson coefficient of concordance showed that the inter-rater reliability and inner-rater reliability was consistent(r=0.932,r=0.913,P<0.01).The t-test was employed to verify the discriminant validity between the clinical and control groups.The result showed that a significant discriminant validity was found with the scoring system developed in this research(t=14.890,P<0.01).Conclusion The scoring system developed from this study has good inter-rater reliability,inner-rater reliability and discriminant validity.

OBJECTIVE To study the protective mechanism of Bawei chenxiang powder containing serum on H9c2 cells injured by oxygen-glucose deprivation (OGD). METHODS H9c2 cells were divided into blank group, model group and Bawei chenxiang powder low-dose, medium-dose and high-dose groups (the dose of drug containing serum 2.5, 8, 12 g/kg). H9c2 cells were cultured in vitro to establish OGD model. After intervention with drug-containing serum, survival rate of cell was detected. The cell morphology was observed; the levels of lactate dehydrogenase (LDH), creatine kinase (CK), superoxide dismutase (SOD), catalase (CAT), respiratory chain complexⅠ (ComplexⅠ), glutathione peroxidase (GSH-Px) and malondialdehyde (MDA) were detected. The contents of reactive oxygen species (ROS), mitochondrial membrane potential and apoptosis were also detected. The expressions of oxidative stress-related proteins [Kelch ECH association protein 1 (Keap1), nuclear factor erythroid 2- related factor 2 (Nrf2), heme oxygenase 1 (HO-1), NADH oxidoreductase coenzyme 10 (Ndufa10), thioredoxin (Trx)] and apoptosis-related proteins [B-cell lymphoma 2 (Bcl-2), Bcl-2 associated X protein (Bax), Caspase-3 and cytochrome C (Cytc)] were detected. RESULTS Compared with blank group, the cell morphology of model group was damaged; the levels of LDH, CK and MDA were significantly increased (P<0.01), while the levels of CAT, ComplexⅠ, SOD and GSH-Px and mitochondrial membrane potential were significantly decreased (P<0.01). The content of intracellular ROS and apoptotic rate were significantly increased (P<0.01); the expressions of oxidative stress-related proteins (Keap1, Nrf2, HO-1, Ndufa10 and Trx) and pro- apoptosis proteins (Bax, Caspase-3 and Cytc) were significantly increased (P<0.05), while the expression of anti-apoptotic protein Bcl-2 was significantly decreased (P<0.05). After administration of Bawei chenxiang powder containing serum, the cell morphology improved, and most of the above indexes were significantly reversed (P<0.05 or P<0.01).CONCLUSIONS Bawei chenxiang powder containing serum E-mail:345783110@qq.com has a good protective effect on H9c2 cells damaged by OGD,the mechanism of which is related to the reduction of oxidative damage and inhibition of cell apoptosis.
