Remote Sensing technology, which is characterized by producing imagery an multi-platform, different temporal and spatial resolution, has greatly improved mankind's capability of acquisition, processing and application of spatial information. The increase of spatial data sources and the development, applications and industrialization of spatial information technology are urging the need of spatial data sharing and exchanging. Based an a brief introduction an the China Spatial Information Network (CSI) and its database system, the CSI Spatial Science and Technology Information Database (SSTID) management system was designed and implemented in this paper.

A series of polyphenylquinoxaline (PPQ) ultrafine non-woven fibrous membranes have been first successfullyprepared via the electrospinning procedure with the soluble PPQ solutions as the starting materials. For this purpose, variousorgano-soluble PPQ resins were synthesized via the one-step high temperature polycondensation procedure from thearomatic ether-bridged bis(α-diketone) and bis(o-diamine) monomers. Flexible ether linkages and pendant bulky phenylsubstituents endowed the PPQ resins good solubility in polar aprotic solvents. The high-molecular-weight PPQ resins weredissolved in N-methyl-2-pyrrolidone (NMP) to afford the PPQ electrospinning solution except PPQ-Ia derived from 4,4'-oxydibenzil (ODB) and 3,3'-diaminobenzidine (DAB) due to the limited solubility in the solvent. All the derived PPQultrafine non-woven fibrous membranes maintained good structure integrity after hydrolysis aging either at room temperature(25 oC) for 72 h or at refluxing temperature (100 oC) for 24 h in an aqueous sodium hydroxide (NaOH) solution at a solidcontent of 20 wt%. Comparatively, the polyimide (PI) reference electrospun membrane (PI-ref) derived from 1,2,4,5-pyrromellitic anhydride (PMDA) and 4,4'-oxydianiline (ODA) lost its original structure only after boiling in the same NaOHsolution within 3 h. In addition, the developed PPQ ultrafine non-woven fibrous membranes exhibited good thermal stabilitywith the 5 % weight loss temperatures (T5%) higher than 555.0 oC in nitrogen and glass transition temperatures (Tg) in therange of 248.1-266.1 oC, respectively.

Background and Purpose: Cisplatin is the most common chemotherapeutic agent for loco-regionally advanced nasopharyngeal carcinoma (NPC); however, toxicity is a limiting factor for some patients. We retrospectively compared the efficacy and toxicity of weekly docetaxel-based and cisplatin-based concurrent chemoradiotherapy in loco-regionally advanced NPC. Methods and Materials: Eighty-four patients with Stage III and IVA-B NPCs, treated between 2007 and 2008, were retrospectively analyzed. Thirty received weekly docetaxel-based concurrent chemotherapy, and 43 were given weekly cisplatin-based concurrent chemotherapy. Radiotherapy was administered using a conventional technique (seven weeks, 2.0 Gy per fraction, total dose 70-74 Gy) with 6-8 Gy boosts for some patients with locally advanced disease. Results: Median follow-up time was 42.3 months (range, 8.6-50.8 months). There were no significant differences in the 3-year loco-regional failure-free survival (85.6% vs. 92.3%; p=0.264), distant failure-free survival (87.0% vs. 92.5%; p=0.171), progression-free survival (85.7% vs. 88.4%; p=0.411) or overall survival (86.5% vs. 92.5%, p=0.298) of patients treated concurrently with docetaxel or cisplatin. Severe toxicity was not common in either group. Conclusions: Weekly docetaxel-based concurrent chemoradiotherapy is potentially effective and has a tolerable toxicity; however, further investigations are required to determine if docetaxel is superior to cisplatin for advanced stage NPC.

Cardiotoxin III (CTX III), a basic polypeptide with 60 amino acid residues isolated from Naja naja atra venom, has been reported to have anticancer activity. CTX III-induced K562 cell apoptosis was confirmed by DNA fragmentation (DNA ladder, sub-G1 for-mation) and phosphatidylserine (PS) externalization with an IC50 value of 1.7 g/ml at 48 h. A mechanistic analysis demonstrated that CTX III-induced apop-totic cell death was accompanied by up-regulation of both Bax and endonuclease G (Endo G), and downregulation of Bcl-XL. CTX III had no effect on the levels of Bcl-2, Bid, XIAP survivin, and AIF proteins. CTX III treatment caused loss of the mitochondrial membrane potential (Ψm), release of mitochon-drial cytochrome c to the cytosol, and activation of both caspase-9 and -3. CTX III-induced apoptosis was significantly blocked by the broad-spectrum cas-pase inhibitor Z-VAD-FMK. However, CTX III did not generate reactive oxygen species (ROS) and talase, did not block CTX III-induced apoptosis in K562 cells. Modulation of Bax, Bcl-XL, and the Endo G proteins, release of mitochondrial cytochome c, and activation of caspase-3 and -9 all are involved in the CTX III-triggered apoptotic process in human leukemia K562 cells.
