Background: To investigate tumor inhibition effects and mechanisms of Angelica sinensis and Sophorae flavescentis ait decoction (ASSF) combined with diamine-dichloroplatinum (DDP). Materials and Methods: Bodyweight, tumor inhibition rate and q value were calculated for single ASSF or ASSF combined with DDP on H22 carcinoma xenograft KM mice. Biochemical methods for serum LDH, AST, ALT, and AKP, ELISA method for serum HIF-$1{\alpha}$, pathological assessemnt of thymus, immunohistochemistry detection of tumor tissue caspase3 and mutant p53 protein, and qRT-PCR detection of bax/ bcl-2 mRNA were applied. Results: Compared with DDP control group, the bodyweight increased in ASSF-DDP group (p<0.01). Tumor inhibition rates for DDP, ASSF, ASSF-DDP were 62.7%. 43.7% and 71.0% respectively, with a q value of 0.90. Compared with other groups, thymus of DDP control group had obvious pathological injury (p<0.01), serum LDH, AST, ALT, AKP increased significantly in DDP control group (p<0.01), while serum HIF-$1{\alpha}$ was increased in the model control group. Compared with this latter, the expression of mutant p53 protein and bcl-2 mRNA were decreased in all treatment groups (p<0.01), but there were no statistical difference between DDP control p and ASSF-DDP groups. The expression of caspase3 protein and bax mRNA was increased in all treatment groups, with statistical differences between the DDP and ASSF-DDP groups (p<0.01). Conclusions: ASSF can inhibit bodyweight decrease caused by DDP, can inhibit tumor growth synergistically with DDP mainly through increasing serum HIF-$1{\alpha}$ and pro-apoptotic molecules such as caspase 3 and bax, rather than through decreasing anti-apoptotic mutant p53 and bcl-2. ASSF can reduce DDP toxicity due to decreasing the release of LDH, AST, ALT, AKP into blood and enhancing thymus protection.
A New Audio Event Detection Method by Using Contextual Information
Qi Hong-zhuo,Chen De-yun 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.3
This paper focuses on audio event detection in tennis match. A new audio event detection method is proposed my making use of contextual information. This method detects the sounds of ball hit and line judge’s shout by the grunts of players when they hit the ball. To model for audio events, the proposed method adopts unsupervised learning to use the information of grunts. Compared with current methods, the proposed method possesses two advantages. First, it does not need any labeled data which is appeal in real applications. Second, this method can reduce the mismatch between training and testing to further improve the performance. Experimental results show that the proposed method can improve the performance of audio event detection substantially.

A new fungus, Ophiocordyceps alboperitheciata, parasitic on the larva of Noctuidae (Lepidoptera) was identified from a survey of entomopathogenic fungi in Kunming Wild Duck Forest Park, Yunnan Province, China. It can be primarily distinguished from relatives by its longer fertile parts, sterile tips, superficial perithecia, narrower asci, and smaller septa of ascospores. As revealed from phylogenetic analyses inferred from nrSSU, nrLSU, tef-1α, rpb1, and rpb2 sequence data, O. alboperitheciata belongs to the Hirsutella citriformis clade in the genus Ophiocordyceps of Ophiocordycipitaceae, and forms a separated clade from other related species. The uniqueness of the taxon is significantly evidenced by both molecular phylogeny and morphology. Furthermore, the interspecific relationships in the H. citriformis clade are discussed.

To evaluate efficacy of microwave ablation in a primary clinical study, sixty patients (44 men, 16 women; mean age 53 years) with 96, 1-8 cm (mean $3.20{\pm}0.17$ cm) liver cancers were treated with 2,450-MHz internally cooled-shaft antenna. Complete ablation (CA) and local tumor progression (LTP) rates as well as complications were determined. CA rates in small (< 3.0 cm), intermediate (3.1-5.0 cm) and large (5.1-8.0 cm) liver cancers were 96.4% (54/56), 92.3% (24/26) and 78.6% (11/14), respectively. During a mean follow-up period of $17.17{\pm}6.52$ months, LTP occurred in five (5.21%) treated cases. There was no significant difference in the CA and LTP rates between the HCC and liver metastasis patient subgroups (P<0.05). Microwave ablation provides a reliable, efficient, and safe technique to perform hepatic tumor ablation.

Mu‐jie Qi,박보선,Cheng-De LI,레수안비,배양섭 한국곤충학회 2013 Entomological Research Vol.43 No.5
Four species of the genus Evergestis Hübner, 1816–1826 are recognized from NE China, of which E. pallidata (Hufnagel 1767) is reported for the first time from China. The adults and genitalia of the species are briefly redescribed and illustrated with their distributional ranges, host plants and biology. A key to species of the genus based on the external characters is provided.

Purpose: Urapidil is putatively effective for patients with hypertension and acute heart failure, although randomized controlled trials thereon are lacking. We investigated the efficacy and safety of intravenous urapidil relative to that of nitroglycerin in older patients with hypertension and heart failure in a randomized controlled trial. Materials and Methods: Patients (>60 y) with hypertension and heart failure were randomly assigned to receive intravenous urapidil (n=89) or nitroglycerin (n=91) for 7 days. Hemodynamic parameters, cardiac function, and safety outcomes were compared. Results: Patients in the urapidil group had significantly lower mean systolic blood pressure (110.1±6.5 mm Hg) than those given nitroglycerin (126.4±8.1 mm Hg, p=0.022), without changes in heart rate. Urapidil was associated with improved cardiac function as reflected by lower N terminal-pro B type natriuretic peptide after 7 days (3311.4±546.1 ng/mL vs. 4879.1±325.7 ng/mL, p=0.027) and improved left ventricular ejection fraction (62.2±3.4% vs. 51.0±2.4%, p=0.032). Patients given urapidil had fewer associatedadverse events, specifically headache (p=0.025) and tachycardia (p=0.004). The one-month rehospitalization and all-cause mortality rates were similar. Conclusion: Intravenous administration of urapidil, compared with nitroglycerin, was associated with better control of blood pressure and preserved cardiac function, as well as fewer adverse events, for elderly patients with hypertension and acute heart failure.

A rotating magnetic field (RMF) was applied in the solidification process of Cu-8Fe alloy. Focus on the mechanism of RMFon the solid solution Fe(Cu) atoms in Cu-8Fe alloy, the influences of RMF on solidification structure, solute distribution, andmaterial properties were discussed. Results show that the solidification behavior of Cu–Fe alloy have influenced through thechange of temperature and solute fields in the presence of an applied RMF. The Fe dendrites were refined and transformed torosettes or spherical grains under forced convection. The solute distribution in Cu-rich phase and Fe-rich phase were changedbecause of the variation of the supercooling degree and the solidification rate. Further, the variation in solute distributionwas impacted the strengthening mechanism and conductive mechanism of the material.

The physical vapour deposition process of serial bideposition is used to fabricate inorganic retardation plates of LaF3, NdF3,Sc2O3 and SmF3. For a deposition angle of 70.the form-birefringent materials exhibit linear birefringence in the range 0.090.13 atwavelength 248 nm. The study shows that NdF3 and Sc2O3 are unsuitable for use at 193 nm, due to excessive absorptive loss, andthat LaF3 is the preferred material.
