Reported here is the fabrication of photopolymer hierarchical micronanostructures through a combinative process of electrospinning and subsequent photolithography. Electrospun SU-8 (epoxy-based negative photoresist)nanofiber films have been patterned into gratings with periods of 100, 200, 300, and 400 μm, respectively. Deposition of a silver nanolayer on these interlaced nanofiber films would lead to the formation of various plasmonic nanostructures,and therefore, giving rise to abundant surface-enhanced Raman scattering (SERS) “hot spots”. In the detection of Rhodamine 6G (R6G), probing molecule, the resultant SERS substrates show both high sensitivity and good reproducibility. The SERS enhancement factor could reach as high as ~108, indicating high efficiency. The fabrication of patterned, highly efficient SERS substrates may hold a great promise for the integration of SERS substrates in various microdevices such as microfluidic chips.
Calibration of Laser Inertial Navigator with Dual-axis Rotation

The calibration of inertial measurement units (IMU) is required to determine the coefficients in the input/output models of inertial sensors. High accuracy turntables and information on the north direction and the local level are usually required in traditional calibration methods. But for a laser inertial navigator with dual-axis rotation, in which the IMU is usually compactly designed, it is usually not convenient to remove the IMU from the navigator to high precision turntable for calibration. To improve the affordability, a simple calibration method is proposed using the dual-axis rotation function of the navigator itself. The method relaxes the orthogonality requirement of the rotation axes and eliminates the need of north information. Rough knowledge of the local plumb-line direction is enough to determine the signs of accelerometer calibration parameters. No re-installation of the IMU is required during the calibration and thus it makes automatic calibration easy to implement. Simulations show that the proposed method is feasible. The proposed method is also tested on an experimental laser inertial navigator with dual-axis rotation, and the navigation results show that the calibration accuracy meets the requirements of high performance inertial navigations.

A new hopane type pentacyclic triterpenoid, 2-hydroxydiplopterol (1) has been isolated from the metabolites produced by the halotolerant fungal strain Aspergillus variecolor B-17. The structure of 1 was determined by spectroscopic methods and single crystal X-Ray diffraction analysis. 2-Hydroxydiplopterol (1) exhibited cytotoxicity against K562 cells with an IC50 value of 22 μM.

In march of 2012, China’s legislature has re-modified the criminal procedure law from eight aspects, including the criminal defense system. After that, in terms of legislation, the status and rights of defense lawyers have great changes so that make China’s criminal defense system to a new level. This paper summarizes, analyses and interprets the new law.

Multi-granularity linguistic information has been studied by researchers in many disciplines, in which the scale of linguistic term sets is usually restricted in domain [0, 1]. In this paper, we consider the multiple attribute group decision making (MAGDM) problems, in which the evaluation of each alternative with respect to each attribute is provided by several experts of the corresponding field. In order to convey the preferences of different experts exactly and to describe the characteristics of different attributes, linguistic term sets with different granularities and different scales have been proposed to express their evaluation values. Moreover, the performance values given by the experts take the form of modified proportional 2-tuples. In this process, the modified proportional 2-tuple, its comparative rules as well as several aggregation operators have been proposed. A new method has been proposed to achieve a basic modified linguistic term set (BMLTS) and a transformation function has been defined to make the performance values uniform. An example is given to illustrate the applicability and flexibility of the method.
Plasma Post-operative miR-21 Expression in the Prognosis of Gastric Cancers

Tumor-associated microRNAs have been detected in serum or plasma, but whether plasma microRNA-21 (miR-21) could be a potential circulating biomarker for gastric cancer (GC) prognosis in Chinese is still uncertain. Real-time quantitative reverse transcription PCR (qRT-PCR) was employed in this study to compare the relative expression of miR-21 between pre-operative and post-operative paired plasmas from 42 patients with primary GCs. The results showed that the expression levels of miR-21 in the post-operative plasmas were significantly reduced by an average of 18.2 times in all patients when compared to the pre-operative plasmas, and by 22.1 times in the subgroup of patients without family history, while only 1.76 times in the subgroup of patients with a family history. With respect of clinicopathological characteristics, the plasma miR-21 expression was highly associated with differentiation degree and lymph node metastasis rate. The results suggested plasma miR-21 could be a novel potential biomarker for GC prognosis and evaluation of surgery outcomes, especially in patients without a family history.
Naringin and Naringenin Relax Rat Tracheal Smooth by Regulating BKCa Activation

Naringin and its aglycone, naringenin, occur naturally in our regular diet and traditional Chinese medicines. This study aimed to detect an effective therapeutic approach for cough variant asthma (CVA) through evaluating the relaxant effect of these two bioactive herbal monomers as antitussive and antiasthmatic on rat tracheal smooth muscle. The relaxant effect was determined by measuring muscular tension with a mechanical recording system in rat tracheal rings. Cytosolic Ca2+ concentration was measured using a confocal imaging system in primary cultured tracheal smooth muscle cells. In rat tracheal rings, addition of both naringin and naringenin could concentration dependently relax carbachol (CCh)-evoked tonic contraction. This epithelium-independent relaxation could be suppressed by BaCl2, tetraethylammonium, and iberiotoxin (IbTX), but not by glibenclamide. After stimulating primary cultured tracheal smooth muscle cells by CCh or high KCl, the intracellular Ca2+ increase could be inhibited by both naringin and naringenin, respectively. This reaction was also suppressed by IbTX. These results demonstrate that both naringin and naringenin can relax tracheal smooth muscle through opening big conductance Ca2+-activated K+ channel, which mediates plasma membrane hyperpolarization and reduces Ca2+ influx. Our data indicate a potentially effective therapeutic approach of naringin and naringenin for CVA.
