无机材料学报 , 2012, DOI: 10.3724/sp.j.1077.2012.00209
Abstract: Y2O3 (5mol%) and Gd2O3 (5mol%) co―doped SrZrO3 (Sr(Zr0.9Y0.05Gd0.05)O2.95, SZYG) was synthesized by solid state reaction method. The phase stability of the SZYG powder synthesized at high temperature of 1450 for a long period and at temperature range of 200?1400 was characterized by XRD and DSC, respectively. The coefficients of thermal expansion (CTEs) of bulk SZYG recorded by a high―temperature dilatometer show that the phase transitions of SrZrO3 is suppressed remarkably by co―doping Y2O3 and Gd2O3. The thermal conductivity of bulk SZYG at 1000 is 1.36 W/(m·K), which is 35% lower than that of bulk SrZrO3 and 8YSZ. The good chemical compatibility of SZYG with 8YSZ and Al2O3, is detected after heat―treatment at 1250 for 24 h.

Abstract: We propose a LBO-based ultra-broadband chirped pulse optical parametric amplifier employing pulse-front-matching to yield transform-limited sub-12-fs pulses. Measurement of the maximum possible gain bandwidth for the LBO-based OPCPA demonstrates more than 60nm gain bandwidth FWHM. For the generation of TL pulses by the use of this OPCPA, a suitable combination of OPCPA and PFM is first presented. The PFM pump geometry realizes tilt-free signal amplification, and permits this OPCPA to generate TL sub-12-fs pulses.

Abstract: The characteristic elements and their assembly of plant can indicate the effect of special geochemical environment on the local plant. In this paper fourteen trace elements in soil and Kaempferia Galangal L samples were measured to explore the feasibility of characteristic elements as the fingerprinting marker of products of origin in Shuangjiao of Yangchun region. The results showed that: there was a significant correlation between the contents of trace elements in soil and in plant; the absorptive capacities of Kaempferia Galangal L. to trace elements were different; Mg, Mn, Zn, Sb, Fe, Cu and Sr were the characteristic elements of Kaempferia Galangal L. by weight analysis. Effect of regional geochemical background on the products of origin should be further explored.

Abstract: In the title compound, [Cu(NO3)2(C14H36N6)](NO3)2·4H2O, the CuII atom, lying on an inversion center, is six-coordinated in a distorted octahedral environment by four N atoms from a centrosymmetric 14-membered tetraazacyclotetradecane macrocyclic ligand and two O atoms from two nitrate anions. The supramolecular network is consolidated by extensive O—H...O and N—H...O hydrogen-bonding interactions.

Abstract: Objective  To evaluate the effect of low-concentration preoxygenation on physical work capacity with a heart rate of 170 beat per minute (PWC170) in recruits arrived on Qinghai-Tibet Plateau (3651m height above sea level), and investigate the possible correlation between new recruits' coping style and physical work capacity. Methods  Thirty-nine recruits coming from plains (799m or 620m height above sea level) were involved in our study. They were randomly divided into 3 groups: experimental group I (n=12), experimental groupⅡ (n=12), and control group (n=15). The group I had 1L/min low concentration preoxygenation for 30min, and groupⅡ had 2L/min for 30min, once a day for 3 days. No preoxygenation in control group. The new recruits's PWC170 values were measured by stepping stairs for evaluating their physical ability, and the new recruits's coping responses were investigated with "Physical Training Coping Scale", and then those data compared with these of 98 soldiers stationed in Tibet (senior soldier group, stationed in Tibet for at least 2 years). Results  Each basic PWC170 values showed no significant diffierence between group Ⅰand Ⅱ (P>0.05). Each basic PWC170 was significantly higher in the experimental groups Ⅰand Ⅱthan in control group (P<0.05). As for the coping style, there was no significant diffierence between experimental group, control group, and senior soldier group (P>0.05). Correlation analysis showed that there was a significant positive correlation between the "active response" factor and basic PWC170 value, and between "emotional management" factor and PWC170 value on second day between the two experimental groups (r=0.329 and 0.344 respectively, P<0.05). There was also a significant correlation between PWC170 values (day 1, day 2 and day 3), and the correlation coefficients were between 0.570 and 0.594 (P<0.01). Conclusions  Low concentration preoxygenation possibly can improve the physical fitness level of new recruits'. To certain extent, the basic PWC170 may be related to the coping style of "active response" of new recruits to Tibet in physical training, while the maintenance of physical fitness level may be associated with "emotional management" factor.

Abstract: Objective: To investigate the effect of ginseng total saponins (GTS) on expression of nerve growth factor in rat with polycystic ovaries.Methods: A total of thirty rats were randomly divided into normal control group, untreated group and GTS group. Polycystic ovaries were induced by a single intramuscular injection of 4 mg estradiol valerate (EV) in rats of the untreated group and GTS group. The rats in the GTS group were administered 50 mg/kg GTS every other day by intraperitoneal injection for 30 days after the EV injection. The expressions of NGF in the ovaries, pituitary and hippocampus were observed by method of immunohistochemistry.Results: Comparison with the normal control group revealed that the expressions of NGF in ovaries, pituitary and hippocampus of rats in the untreated group were increased (P<0.05). The ovarian morphology of the GTS group was almost as normal as that of the normal control group. As compared with the untreated group, the expression of NGF in ovaries of the rats in GTS group was obviously decreased (P<0.05), while the expression of NGF in pituitary and hippocampus showed on difference. Conclusion: GTS can decrease the expression of NGF in ovary tissue in rats with polycystic ovaries induced by EV, which may be its mechanism in lessening the polycystic ovary.

Journal of Chongqing Normal University , 2010,
Abstract: The WLAN treats wireless channel as transmission medium, but its open characteristics cause wiretapping ,identity threats, counterfeiting and tampering of information are actually ubiquitous. In this paper, based on cloud computing model, we set up hundreds of millions of times per second, super-computing platform;Secondly, we crack WEP the most common WLAN encryption protocol to verify a series of safety mechainsm proposed by IEEE 802.11 to be ineffective, such as identiffication authentication and the data encryption and so on. Then we use the experimental data to prove the system supported by cloud computing threat WLAN's reliability and security seriously, to shorten the time to crack thousands of times; inally, we recommend WAP/WPA2and TKIP to replace simple fixed RC4 as solution.
Antimetastatic therapy targeting aberrant sialylation profiles in cancer cells

Drugs and Therapy Studies , 2010, DOI: 10.4081/dts.2011.e12
Abstract: Neoplasm metastases involve a fixed cascade of pathological processes, and are responsible for more than 60% cancer deaths worldwide and can only be controlled or inhibited by drugs now. Antimetastatic drugs targeting aberrantly sialylated in tumors have involved about a quarter of a century and might be a future therapeutic option apart from currently utilized antimetastatic drugs, such as antivascular and matrix metalloproteinase (MMP) inhibitors. Since neoplasm tissues often manifest high levels of sialic acids and sialyl antigens or glycoligands, and some types of sialic acid analogue, such as N-glycolylneuraminic acid (Nau5Gc) occurred in most tumor tissues, is absent in common humans, more attentions are needed to work with new therapeutic approaches to target these changes. Previously preliminary data have shown some compounds that inhibit some pathways of sialic acids can inhibit the tumor metastasis in vitro and tumor metastasis in experimental animal models. This type of pharmacological work can be helped by glycome investigations in order to deep understanding their mechanisms. As the central dogma of glycobiology is still unknown, some fundamental questions related to carbohydrate itself are even more welcoming and decisive to our understanding to nature of cancer. These types of work also need mathematical analysis of data. In this review, we will document and discuss the latest experimental therapeutic data and their clinical significance between cancer pathological profiles and therapeutics benefits.
