Studies on the in Vitro Dissolution of Insoluble Volatile Drug from Su-Anxin Nasal Inhalant and Its Correlation on the Nose Steady Self-Controllable Expiration and Inspiration at Night  [PDF]
Xiaodong Li, Guoxiang Xie, Suyun Li, Chao Hou
Pharmacology & Pharmacy (PP) , 2011, DOI: 10.4236/pp.2011.22008
Abstract: In the paper, the in vitro dissolution of borneol in 12 hours from 6 batches of optimized inhalant samples were investigated. As a new dosage form, the in vitro release apparatus of nasal inhalant was invented and a pushing bump was used according to the simulation of the nose expiration and inspiration. Based on the data of r2 in the profile and similar factor f2 from 6 linear release tendencies, a good controlled release and a zero order tendency were observed. It can be suggested that there is a good correlation between the in vitro controlled release and the nose steady self-controllable expiration and inspiration, which will contribute to the trend of insoluble volatile drug controlled release and the effect of quick absorption in nasal pulmonary delivery to cure severe or acute cardiovascular or lung diseases at patients' sleeping, such as angina or breathing obstruction. Also, it was concluded that the prescription composed of insoluble volatile drugs can be prepared to be nasal inhalant from which drugs can be absorbed through nose steady self-controllable inspiration to the lung then into the blood and have a great effectiveness improvement of bioavailability at night timing drug delivery system.

Abstract: Pattern recognition receptors play an important role in insect immune defense. We cloned the β-1,3-glucan recognition protein, lectin-5 and C-type lectin 1 genes of Antheraea pernyi and examined the expression profiles of immune-stimulated pupae. After infection with Bacillus subtilis, Escherichia coli, Antheraea pernyi nuclear polyhedrosis virus ( ApNPV) and Saccharomyces cerevisiae, respectively, the pupae showed different gene expression levels in the different tissues examined (midgut, fatbody, epidermis, testis, and hemocytes). ApβGRP and Aplectin-5 was induced by all the microorganisms, and mainly in epidermis and hemocytes, but not in testis; Aplectin-5 was also expressed in fatbody. Ap C-type lectin 1 was, on the contrary, highly expressed in testis and also in fatbody, but not in hemocytes. Unlike ApβGRP and Aplectin-5, Ap C-type lectin 1 was not induced by Gram-positive bacteria. The results suggest that the cloned lectins may have different functions in different tissues of A. pernyi.

Guomin Zhang,Suyun Wang,Li Li,Xiaodong Zhang,Hongsheng Ma
Chinese Science Bulletin , 2002, DOI: 10.1007/BF02907562
Abstract: Focal depth data of earthquakes in Mainland China are processed and analyzed in this paper, as well as the relationship between the focal depths and large-scale tectonic structures. As a basic parameter for earthquakes, focal depth is used to investigate deep environment of seismogenic regions, tectonic backgrounds for concentration and release of seismic energy, the inner crustal deformation and its mechanic features. Depth data of 31282 Ml 2.0 events with 1st class and 2nd class precision in Mainland China from Jan. 1, 1970 to May 31, 2000 are used to get spatial features of earthquakes distributed with depth and to provide average depth for each grid area throughout China. Researches show that the average depth (D) for all the earthquakes used in this paper is (16 ± 7) km, and (13 ± 6) km and (18 ± 8) km for the events in eastern China and western China, respectively. The area with the deepest focal depth is located in southwest Xinjiang region, near the western and southwestern ends of the Tarim Basin. The focal depth related to large-scale tectonic structures, for instance, D= (33 ± 12), (21 ± 10), (14 ± 7), (11 ± 5) and (10±4) km in Tibet plateau block, Xinjiang block, North China, Northeastern China and South China, respectively. The earth-quakes are deeper at the bounders of the integrated tectonic blocks, including the southwestern and northern brims of the Tarim Basin, southern brim of the Zhunge’r Basin and that of the Alashan block, as well as the eastern and western sides of the Edos block and the western brim of the Sichuan Basin. The earthquakes at the newly ruptured belts are relatively shallower, for instance, at the southwestern Yunnan seismic belt and the Zhangjiakou-Bohai seismic belt. The mechanic behavior, deformation and features for the crust and mantle structures are also discussed.

Abstract: CD105 is a well-known tumor metastasis marker and useful for early monitoring of metastasis and cancer relapse. It is important to generate rapid, reliable and precise analytical information regarding CD105 levels. To establish a simple, selective and sensitive detection method, we prepared an immunosensor with novel bioconjugates based on Pt nanoparticles, thionin acetate and antibodies. The proposed immunosensor displayed a broader linear response to CD105, with a working range of 1.3 to 200.0 ng/mL and a detection limit of 0.9 ng/mL under optimal conditions. Moreover, the studied immunosensor exhibited high sensitivity, fast analysis and adequate stability. The proposed methodology could readily be extended to other clinical- or environment-related biospecies.
Mixed-Mean Inequality for Submatrix
Lin Si,Suyun Zhao
Mathematics , 2010,
Abstract: For a $m\times n$ matrix $B=(b_{ij})_{m\times n}$ with nonnegative entries $b_{ij}$ and any $k\times l-$submatrix $B_{ij}$ of $B$, let $a_{B_{ij}}$ and $g_{B_{ij}}$ denote the arithmetic mean and geometric mean of elements of $B_{ij}$ respectively. It is proved that if $k$ is an integer in $(\frac{m}{2}, m]$ and $l$ is an integer in $(\frac{n}{2}, n]$ respectively, then $$\Big(\prod_{i=k,j=l\atop B_{ij}\subset B}a_{B_{ij}}\Big)^{\frac{1}{C_m^k\cdot C_n^l}} \geq\frac{1}{C_m^k\cdot C_n^l}\Big(\sum_{i=k,j=l\atop B_{ij}\subset B}g_{B_{ij}}\Big),$$ with equality if and only if $b_{ij}$ is a constant for every $i,j$.

Tongfei Tu, Suyun Luo
Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104559
In order to solve the problem that the PKE (passive keyless enter) with a fixed-frequency used in middle and low grade cars was interfered and broken easily, which led to the damage of anti-theft system and even the loss of cars, and in order to ensure the PKE can be used long and be expanded and upgraded in the future, a new, low power consumption and high reliability PKE was designed with the S3C2410 microprocessor which is based on ARM9 and the RF transceiver chip nRF905 which has the function of frequency modulation. As frequency-hopping communication technology was used in the system, the information would not be disturbed or blocked in the communication process, which increased the reliability of the system. With reasonable power-management module, the system power consumption was greatly reduced. Test shows that the new PKE can well meet the practical application.
Pedestrian Detection with Improved LBP and Hog Algorithm  [PDF]
Wei Zhou, Suyun Luo
Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104573
This article aims to improve the HOG SVM pedestrian detection method proposed by previous researchers. The speed of HOG SVM to detect pedestrians is relatively slow, and the detection accuracy is not very good. This paper proposes a PCA (principal component analysis) dimension reduction for HOG and also interpolates it. The article combines the dimensions of individual HOG features and improves their accuracy, and fuses them with improved LBP features. The features of the fusion of HOG features and LBP features can both express pedestrian profile information and obtain pedestrian texture information. This can improve the speed of pedestrian detection and improve the accuracy of detection, which is beneficial to reduce false detection and missed detection. Although some researchers have combined the two features of HOG and LBP, after simple fusion of these two features, the experimental results show that the detection effect is not much improved. This article is aimed at different formats of video detection material, an application program written on the MFC platform, making pedestrian detection of the material quickly verified, which is conducive to pedestrian detection results data analysis and recording.
