Based on the background of macro-political environment of China from 1978 to 2016, this paper tries to outline the development path of Chinese cultural policy in order to better understand Chinese current cultural production and consumption. China, as a socialist country, has a strong macro-guiding capacity through making policies. Cultural policy is also heavily affected by the macro national policy. That is why only through the background of macro-political environment, the development path of Chinese cultural policy can be understood clearly. According to means of literature research, policy text analysis, and data comparisons and so on, this paper divides and discuss the development path of Chinese cultural policy into four stages. On one hand, in each stage, the most important changes on cultural policy are described and the formations of important concepts are discussed. On the other hand, it is explained how the four stages are combined as one through the problems in real social conditions. The development path of Chinese cultural policy is complex, dynamic, and extensive. Therefore, because of the limited number of words and important but relatively less perspectives, it is very difficult that the dynamic process are studied perfectly. However, the paper has meaning for aiming to inspire that more studies on Chinese cultural policy would be researched from lots of other perspectives.

Excited states of 113In have been populated through the heavy-ion fusion evaporation reaction 110Pd(7Li, 4n)113In. A new band with the configuration of a proton d5/2 orbital is identified. Two ΔI = 2 intruder bands, built on the πh11/2 and the πg7/2 orbitals, have been extended to spins (63/2-)ħ and (55/2+)ħ, respectively. The negative-parity πh11/2 intruder band shows a smooth increase in aligned spin, which is attributed to a strong proton-neutron interaction. The properties of the positive-parity πg7/2 band are discussed based on tilted axis cranking model calculations, and the features of the antimagnetic rotation for this band are shown after backbend. Furthermore, the contributions of the two-shears-like mechanism, the neutron (gd)ν shell and the core rotation are investigated for the positive-parity πg7/2 band.

In this work, flake-like poly(2,3-dimethylaniline) (P(2,3-DMA)) with enhanced thermal stability andanticorrosive ability was synthesized by in situ polymerization using H2O2/Fe2+ catalytic oxidation system, comparingwith traditional oxidant ammonium persulfate (APS) synthetic method. The structure and morphology of thesamples were characterized Fourier transform infrared (FTIR) spectra, X-ray diffraction (XRD) and field-emissionscanning electron microscope (FESEM). The experimental results demonstrated that using H2O2/Fe2+ catalytic oxidationsystem was more inclined to form the two-dimensional P(2,3-DMA) flakes. The enhancement in thermostabilityand corrosion resistance was attributed to the formation of phenazine-like structures in the polymer chains,which could serve as templates to form the flake-like morphology. In addition, using H2O2/Fe2+ catalytic oxidationsystem is more environmental friendly than the APS method that can avoid ammonium pollution on aquatic life aswell as waters.
H∞ Control with Multiple Packets Compensation Scheme for T-S Fuzzy Systems Subject to Cyber Attacks

This paper is concerned with the H∞ controller design problem for a class of network-based nonlinearsystems (NCSs) represented by the Takagi-Sugeno (T-S) fuzzy model. A multiple packets compensation schemeis developed which uses all the data stored in a finite memory buffer to compensate the negative effects of packetdropouts. This model contains the medium access constraint problem as a special case. The time-multiplexingmechanism may be used for such a case so that there are multiple packets arrive at the receiver side. By taking thestochastic cyber attacks into account, the desired controller in terms of linear matrix inequalities (LMIs) is designedby using fuzzy-rule-dependent Lyapunov method. The sufficient condition is obtained which makes the closed-loopsystem be asymptotically mean-square stable and achieve the prescribed H∞ disturbance-rejection-attenuation level. Finally, a mass-spring-damping system is given to show the effectiveness of the algorithm.

Scutellaria barbata D. Don (S. barbata), a traditional Chinese medicine, is used to treat cancers, inflammation, and urinary diseases. This study aimed to determine any protective effects of S. barbata crude extract (CE-SB) against rat liver tumorigenesis induced by diethylnitrosamine (DENA). Liver malfunction indices in serum were measured by biochemical examination. Hematoxylin and eosin staining was performed to examine liver pathology. Contents of malondialdehyde (MDA) and superoxide dismutase (SOD) were measured in liver homogenates to evaluate oxidative stress. The levels of liver malfunction indices in the CE-SB groups, especially in the CE-SB high dose group, were lower than that of the model group (P<0.05). The results from histological examination indicated that the number of liver nodules in the CE-SB groups decreased compared with the model group (P<0.05). Content of MDA determined in liver was significantly decreased, and level of SOD elevated by CE-SB. CE-SB can inhibit experimental liver tumorigenesis and relieve hepatic injury in rats.

While screening for cellulase-producing fungi from insect gut, a fungus with high endoglucanase (carboxymethylcellulase; CMCase) activitywas isolated fromthe larval gut of Bombyx mori. Based onmorphological characteristicsand using an 18S rRNA-based molecular phylogenetic approach, the fungus, strain BMC-2, was identified as aMucor sp. expressing a novel alkalotolerant cellulase. The maximum production of cellulase by the BMC-2 strainwas observed at 55°C and pH8.0. The CMCase activity was inhibited by Cu2+ N Na+ N Zn2+ N Mg2+ N Ba2+, andinduced by Ca2+, Mn2+, Fe2+, and K+.

Background: This study aimed to summarize the potential diagnostic value of serum DKK1 levels in cancer detection. Materials and Methods: Serum DKK1 was measured using enzyme-linked immunosorbent assay in a case-control study. Then we performed a meta-analysis and the pooled sensitivity, specificity, diagnostic odds ratio, and summary receiver operating characteristic (sROC) curves were used to evaluate the overall test performance. Results: Serum DKK1 levels were found to be significantly upregulated in gastric cancer as compared to controls. ROC curve analysis revealed an AUC of 0.636, indicating the test has the potential to diagnose cancer with poor accuracy. The summary estimates of the pooled sensitivity, specificity and diagnostic odds ratio in meta-analysis were 0.55 with a 95% confidence interval (CI) (0.53-0.57), 0.86 (95%CI, 0.84-0.88) and 12.25 (95%CI, 5.31-28.28), respectively. The area under the sROC was 0.85. Subgroup analysis revealed that the diagnostic accuracy of serum DKK1 in lung cancer (sensitivity: 0.69 with 95%CI, 0.66-0.74; specificity: 0.95 with 95%CI, 0.92-0.97; diagnostic odds ratio: 44.93 with 95%CI, 26.19-77.08) was significantly higher than for any other cancer. Conclusions: Serum DKK1 might be useful as a noninvasive method for confirmation of cancer diagnosis, particularly in the case of lung cancer.
