PREPARATION OF MACROPOROUS CELLULOSE-BASED SUPERABSORBENT POLYMER THROUGH THE PRECIPITATION METHOD
Yu Chen,Yunfei Liu,Hui-Min Tan
BioResources , 2008,
Abstract: Superabsorbent polymer was prepared by graft polymerization of acrylic acid onto the chain of carboxymethyl cellulose. This superabsorbent polymer was further treated by the solvent precipitation method. We found that the water absorption rate of the treated polymer was greatly increased and the microstructure of the treated polymer was changed from close-grained structures to loose macropores. The swelling processes of the polymers before and after modification fit first-order dynamic processes. The amount of the residual acrylic acid detected through high performance liquid chromatography (HPLC) with aqueous solution of MOPS of 0.02mol/L (pH=5.70) as the mobile phase. It was found that the amount of the residual acrylic acid decreased from 83.8×10-4 % to 6.7×10-4 % after treatments.

Abstract: BACKGROUND: Chronic severe hepatitis is a critical disease with high mortality. Currently, effective drugs and therapy still lack. Comprehensive and supportive treatment, artificial liver and liver transplantation are the main therapies. A great number of studies on traditional Chinese medicine (TCM) in many ways combined with Western medicine treatment for chronic severe hepatitis have been reported, but the efficacy and safety still lack systematic evaluation.OBJECTIVE: To evaluate the efficacy and safety of integrative medicine therapy for chronic severe hepatitis.SEARCH STRATEGY: Literature was searched from PubMed, the Cochrane Library, the China National Knowledge Infrastructure Database, the Chongqing VIP Chinese Science and Technology Periodical Database, the Chinese Biomedical Literature Database and Wanfang Database. The time limitation ran from the commencement of each database to February 29, 2012.INCLUSION CRITERIA: Randomized controlled trials (RCTs) testing Chinese herbal medicine (CHM) combined with Western medicine (comprehensive and supportive treatment or artificial liver plasma exchange) against Western medicine were included.DATA EXTRACTION AND ANALYSIS: Two authors collected and extracted data independently. The methodological quality of literature was assessed by risk of bias table from Cochrane Collaboration and the data were analyzed by RevMan 5.1 software. Heterogeneity of the included studies was checked by Chi-square test. The efficacy measure was relative risk (RR) or mean difference with a 95% confidence interval (CI).RESULTS: A total of 45 RCTs involving 4 449 patients with chronic severe hepatitis were included. Quality of all included trials was low. The oral CHM, enema and combined TCM with either Western medicine or plasma exchange were superior to Western medicine alone in improving total effective rate and reducing mortality with significant differences. In laboratory parameters, the integrative medicine treatment group was better than Western control group in reducing the total bilirubin and alanine aminotransferase, but two groups showed equal efficacy in lowering aspartate aminotransferase activity. The oral Chinese medicine combined with Western medicine or plasma exchange was better than Western medicine used alone in improving albumin synthesis and coagulation function, but Chinese medicine enema had no significant effect on the level of plasma albumin. The main side effects of the treatment group were abdominal pain, diarrhea and other intestinal symptoms after enema, while adverse reactions of the control gro

Abstract: Particle Swarm Optimization (PSO) has been successfully applied to many optimization problems on real search space. For integer programming, there exist some difficulties and problems for the direct applications of PSO due to the variables belonging to the set of integers. In this paper, a new PSO algorithm is presented for integer programming, which evolves on the set of Integer space. The results regarding the performance of PSO algorithm on the class of problems are reported.
Astataricusones A–D and Astataricusol A, Five New Anti-HBV Shionane-Type Triterpenes from Aster tataricus L. f.

Molecules , 2013, DOI: 10.3390/molecules181214585
Abstract: Five new shionane-type triterpenes, astataricusones A–D (compounds 1– 4) and astataricusol A ( 5), together with one known shionane-type triterpene 6 were obtained from the roots and rhizomes of Aster tataricus L. f. Their structures were elucidated on the basis of spectroscopic data, mainly NMR and MS data. The absolute configurations of 1 and 4 was determined by single crystal X-ray diffraction and CD analysis. Compound 2 showed inhibitory activity on HBsAg secretion with an IC 50 value of 23.5 μM, while 2 and 6 showed inhibitory activities on HBeAg secretion with IC 50 values of 18.6 and 40.5 μM, and cytotoxicity on HepG 2.2.15 cells with CC 50 values of 172.4 and 137.7 μM, respectively. Compounds 2 and 6 also exhibited inhibitory activities on HBV DNA replication with IC 50 values of 2.7 and 30.7 μM, respectively.
A SCHEME FOR OBTAINING HIGH GAIN-LENGTH PRODUCT IN RECOMBINATION X-RAY LASER BY USING A LOW DENSITY TARGET

PENG HUI-MIN,

中国物理 B , 1995,
Abstract: A scheme for obtaining high gain-length product(GL) of recombination X-ray laser is proposed and theoretically studied, in which a thin fiber with a density less than the critical one is driven by a short pulse laser. The features of laser-produced plasma and the gain coefficients of the transition from n = 3 to n = 2 of the H-like ions for a solid fiber and a low-density cylindrical target of carbon are shown. The Sobolev escape probability in a self-similarly expanding cylindrical geometry is used to evaluate the trapping effect on the gain coefficient. According to the simulations there are three obvious advantages of the low-density target, ie., wider gain region, longer lasing duration and no drift of the gain region. In addition, only a few joules are needed for getting saturated GL value.

Computer Science , 2005, DOI: 10.1016/j.jcss.2007.10.004
Abstract: We investigate the condition under which the Eulerian trail of a digraph is unique, and design a finite automaton to examine it. The algorithm is effective, for if the condition is violated, it will be noticed immediately without the need to trace through the whole trail.

Computer Science , 2007,
Abstract: Thermalcycler were extensively used machine for amplify DNA sample. One of the major problems in the working time was that it spent most of time for cooling and heating. In order to improve the efficient, this study presented a novel method for amplify DNA sample. For this concept, the DNA sample in the silicon chamber which was pushed by a beam through three temperature regions around a center and then the DNA segments could be amplified rapidly after 30 cycles. The polymerase chain reaction platform was composed of thin-film heaters, copper plates, DC powers, and temperature controllers. The photolithography and bulk etching technologies were utilized to construct the thin-film heater and DNA reaction chambers. Finally, 1 pound gL 100bp DNA segment of E. coli K12 was amplified successfully within 36 minutes on this PCR platform.
