Thanks to popularization of dance education and its spread over institutions such as art centers, culture centers, palaces for the youth(the organizations for political and cultural activities), universities, and middle schools, people of all social classes in China have formed a complete education system for dance and strengthened it for a few years. This study analyzes the current condition of dance education in China, based on Beijing dance academy and Beijing university of teaching, suggests the features of dance education in both schools; it investigates dance, classification and curriculum in the middle/high schools attached to Beijing dance academy and explores the dance education in primary schools and outside schools. Beijing dance academy had been founded in 1954 and was ratified in 1978 by Ministry of Culture. Currently, it has five majors (acting, choreography, dance studies, visual art design of acting, and management of public utilities), 9 dance departments, a center for life-long education, a center for training teachers, dance troupe of the youth, and a secondary dance school. The academy has an authority to grant a master degree of dance and qualification for training students with a master degree of research in 36 fields. Each department has different purpose and training course; there is a distinction between Chinese traditional dance and dance of Chinese people in educational objective. Beijing university of teaching was established in 1954; dance department belongs to Music School in the university; the school is designed to develop talent, competent students, by means of continuous dance performance, courses for creating dance movement, basic course, and courses for dance theories. The major classes consist of ballet, Chinese dance, dance of Chinese people, modern dance, dance choreography, production, creation, repertoire, dance theories, and sports dance; the courses of dance theories are composed of analysis of works, the history of dance in China and foreign countries, dance esthetics, a methodology of dance for Chinese people, an introduction to art, and the department of business administration for dance art. Dance in China is largely divided higher into vocational education, aiming to develop capable dancers; they are encouraged to realize their full potentials, based on acquisition of a vast basics and in-depth knowledge. Looking into the subject classification and curricular assignment in the middle, high schools attached to Beijing dance academy, dance education in China is mostly focused on training both amateurs in universities and professionals of the organizations concerned; there are about 108 secondary dance schools in a city. China is changing rapidly in the 21st century; it is believed that science has a important role in China's prosperity, with education being fundamental; organization, integration of dance education has come as a new challenge. Faced with the era of innovation, development, the dance business in China is said to be the age of science. For improvement in China dance, more systematic approach to it is required.

( Tian Pei ),( Chen Guozhen ),( Li Nianfeng ) 한국인터넷정보학회 2019 KSII Transactions on Internet and Information Syst Vol.13 No.12

When the length of sampling data sequence is too large, the method of gesture recognition based on traditional Dynamic Time Warping (DTW) algorithm will lead to too long calculation time, and the accuracy of recognition result is not high.Support vector machine (SVM) has some shortcomings in precision, Edit Distance on Real Sequences(EDR) algorithm does not guarantee that noise suppression will not suppress effective data.A new method based on Improved Interpolation Dynamic Time Warping (IIDTW)algorithm is proposed to improve the efficiency of gesture recognition and the accuracy of gesture recognition. The results show that the computational efficiency of IIDTW algorithm is more than twice that of SVM-DTW algorithm, the error acceptance rate is FAR reduced by 0.01%, and the error rejection rate FRR is reduced by 0.5%.Gesture recognition based on IIDTW algorithm can achieve better recognition status. If it is applied to unlock mobile phone, it is expected to become a new generation of unlock mode.

The aim of this study was to compare the functional characteristics of mesenchymal stromal cells (MSCs) from a sheep model of traumatic temporomandibular joint (TMJ) fibrous and bony ankylosis. A sheep model of bilateral TMJ trauma-induced fibrous ankylosis on one side and bony ankylosis on the contralateral side was used. MSCs from fibrous ankylosed callus (FAMSCs) or bony ankylosed callus (BA-MSCs) at weeks 1, 2, 4, and 8 after surgery were isolated and cultured. MSCs derived from the bone marrow of the mandibular condyle (BM-MSCs) were used as controls. The MSCs from the different sources were characterized morphologically, phenotypically, and functionally. Adherence and trilineage differentiation potential were presented in the ovine MSCs. These cell populations highly positively expressed MSC-associated specific markers, namely CD29, CD44, and CD166, but lacked CD31 and CD45 expressions. The BA-MSCs had higher clonogenic and proliferative potentials than the FA-MSCs. The BA-MSCs also showed higher osteogenic and chondrogenic potentials, but lower adipogenic capacity than the FA-MSCs. In addition, the BA-MSCs demonstrated higher chondrogenic, but lower osteogenic capacity than the BM-MSCs. Our study suggests that inhibition of the osteogenic and chondrogenic differentiations of MSCs might be a promising strategy for preventing bony ankylosis in the future.

PKM2 Regulates Hepatocellular Carcinoma Cell Epithelial-mesenchymal Transition and Migration upon EGFR Activation

Fan, Fang-Tian,Shen, Cun-Si,Tao, Li,Tian, Chao,Liu, Zhao-Guo,Zhu, Zhi-Jie,Liu, Yu-Ping,Pei, Chang-Song,Wu, Hong-Yan,Zhang, Lei,Wang, Ai-Yun,Zheng, Shi-Zhong,Huang, Shi-Le,Lu, Yin Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.5

Pyruvate kinase isozyme type M2 (PKM2) was first found in hepatocellular carcinoma (HCC), and its expression has been thought to correlate with prognosis. A large number of studies have demonstrated that epithelial-mesenchymal transition (EMT) is a crucial event in hepatocellular carcinoma (HCC) and associated metastasis, resulting in enhanced malignancy of HCC. However, the roles of PKM2 in HCC EMT and metastasis remain largely unknown. The present study aimed to determine the effects of PKM2 in EGF-induced HCC EMT and elucidate the molecular mechanisms in vitro. Our results showed that EGF promoted EMT in HCC cell lines as evidenced by altered morphology, expression of EMT-associated markers, and enhanced invasion capacity. Furthermore, the present study also revealed that nuclear translocation of PKM2, which is regulated by the ERK pathway, regulated ${\beta}$-catenin-TCF/LEF-1 transcriptional activity and associated EMT in HCC cell lines. These discoveries provide evidence of novel roles of PKM2 in the progression of HCC and potential therapeutic target for advanced cases.

Objective: To investigate the patterns of antipsychotic use in China and to analyze the factors that influence antipsychotic prescriptions. Methods: A standardized survey was conducted from May 20 to 24 2002 in five different regions of China with varying economic levels. The patterns of antipsychotic medication use were analyzed in a sample of 4,779 patients with schizophrenia. The survey gathered information on demographic characteristics, clinical profiles, and antipsychotic medications prescribed. Multiple logistic regression was used to analyze factors related to patterns of antipsychotic medication use. Results: A plurality of patients with schizophrenia was treated with clozapine (39%); this was followed by risperidone, sulpride,chlorpromazine, perphenazine, and haloperidol. More than 56.3% of patients were treated with only one atypical antipsychotic. The mean daily dose of chlorpromazine was 365±253 mg (mean±standard deviation), and 6.5% of patients were treated with depot injections of typical antipsychotic medications. A total of 73.7% (n=3,523) of patients with schizophrenia received monotherapy,24.8% (n=1,183) received two antipsychotics, 1.1% (n=52) received three antipsychotics, and one received four different antipsychotics. Patients often simultaneously received other classes of medications including anticholinergic agents, benzodiazepines,β-blockers, antidepressants, and mood stabilizers. Economic status and clinical symptoms were the main factors that contributed to the patterns of antipsychotic prescription. Conclusion: The present study suggests that atypical antipsychotic medications, especially clozapine, are the primary psychiatric treatments of choice in the management of schizophrenia in China. Moreover, the economic status and clinical profile of the patient are the major factors affecting the prescription of antipsychotic medication.

Effects of Exogenous Elicitors on Triterpenoids Accumulation and Expression of Farnesyl Diphosphate Synthase Gene in Inonotus obliquus

Pei Lin,Zheng-Fei Yan,Chang-Tian Li 한국생물공학회 2020 Biotechnology and Bioprocess Engineering Vol.25 No.4

Exogenous elicitors can influence accumulation of triterpenoids by regulating FPS (farnesyl pyrophosphate synthase) in Inonotus obliquus, such as birch bark (BB), birch rhizosphere soil (BS), Frankia alni (FA), and Rhizobium indigoferae (RI). Among them, the highest yield of biomass (15.6 mg/mL) could be detected by treatment with RI at 2 μg/mL for 10 d, about 2.1-fold of the control. Results showed the significant effect of elicitors on accumulation of triterpenoids by regulating FPS expression level. RI stimulated mycelium to achieve the highest accumulation of triterpenoids about 48.2 mg/g, which was about over 4-fold of the control (9.5 mg/g). Its effect on FPS expression level was greater than that of others, which was about over 10-fold of the control. However, accumulation of triterpenoids and FPS expression level were clearly down-regulated under treatment with BS. In addition, two endogenous factors (H2O2 and NO) in I. obliquus could affect accumulation of triterpenoids by regulating FPS expression level. Effect of RI on H2O2 and NO contents were higher than that of others, about 3.5-fold of the control. The minimum value of H2O2 content was detected by treatment with BS for 10 d, which was about 0.5-fold of the control. RI that assist with CAT (catalase) and SNP (sodium nitroprusside dehydrate) could stimulate triterpenoid contents to achieve highest accumulation, which was about 5.5-fold of the control. Fluctuation of H2O2 and NO content seems to play a pivotal role in accumulation of triterpenoids by regulating FPS expression level.

Purpose Triple-negative breast cancer (TNBC) is highly malignant and has poor prognosis and a high mortality rate. The lack of effective therapy has spurred our investigation of new targets for treating this malignant cancer. Here, we identified RON (macrophage-stimulating 1 receptor) and MET (MET proto-oncogene, receptor tyrosine kinase) as a prognostic biomarker and therapeutic targets for potential TNBC treatment. Materials and Methods We analyzed RON and MET expression in 187 primary TNBC clinical samples with immunohistochemistry. We validated the targeted therapeutic effects of RON and MET in TNBC using three tyrosine kinase inhibitors (TKIs): BMS-777607, INCB28060, and tivantinib. The preclinical therapeutic efficacy of the TKIs was mainly estimated using a TNBC xenograft model. Results Patients with TNBC had widespread, abnormal expression of RON and MET. There was RON overexpression, MET overexpression, and RON and MET co-overexpression in 63 (33.7%), 63 (33.7%), and 43 cases (23.0%), respectively, which had poor prognosis and short survival. In vivo, the TKI targeting RON ant MET inhibited the activation of the downstream signaling molecules, inhibited TNBC cell migration and proliferation, and increased TNBC cell apoptosis; in the xenograft model, they significantly inhibited tumor growth and shrank tumor volumes. The TKI targeting RON and Met, such as BMS-777607 and tivantinib, yielded stronger anti-tumor effects than INCB28060. Conclusion RON and MET co-overexpression can be significant pathological characteristics in TNBC for poor prognosis. TKIs targeting RON and MET have stronger drug development potential for treating TNBC.
