This study attempted to develop an appropriate catalyst used for the steam reforming of gasified spent solvents. Rh2O3/ CeOE-Al2O3 catalysts with various CeO2 loadings were prepared and heated at different temperatures of 500 and 800 ℃, and their surface properties were studied using X-ray diffraction （XRD）, X-ray photoelectron spectroscopy （XPS）, transmission electron microscopy （TEM）, temperature programmed reduction （TPR） and Bmmauer-Emmett-Teller （BET） analyses. Rhodium existed in the form of Rh2O3, regardless of the sample composition as well as the heating temperature. In the tested range of cerium addition （up to 12 times the rhodium mass）, no significant changes in BET surface areas and binding energy corresponding to Rh 3d5/2 were observed. Instead, the addition of cerium led to a greatly enhanced dispersion of rhodium nanoparticles, and no agglomeration of rhodium was observed for samples heated even at 800 ℃. Honeycomb monolith rhodium catalysts promoted with cerium were fabricated and tested for the steam reforming of a gasified spent solvent, mainly consisting of butylene （C4H8）. The test results suggested that a cerium-promoted rhodium catalyst could be used as an appropriate reforming catalyst for treating low-quality non-methane hydrocarbons without the formation of coke at high temperatures of up to 900 ℃.

OBJECTIVE: Symptom patterns are an important diagnostic concept in terms of Traditional Chinese Medicine. Although symptom patterns and healthrelated quality of life(HRQOL) are common diagnostic measures for cancer patients, the association between them has not been studied. This study aimed to describe the changes in the pattern of symptoms of yang-deficiency, Yin-deficiency, blood stasis, and HRQOL before and after chemotherapy,and to examine the association between the patterns and the cancer patients' ***: A panel study was undertaken with 123 cancer patients who were about to begin their first course of chemotherapy at four teaching hospitals in Taiwan. A structured questionnaire was used before and after chemotherapy. HRQOL was assessed using the Medical Outcomes Survey Short-Form 36. The Traditional Chinese Medical Constitutional Scale was used to measure yang-deficiency, Yin-deficiency, and blood stasis patterns,with higher scores indicating a larger ***: The patients had significantly worse scores for yang-deficient pattern, Yin-deficiency pattern, blood stasis pattern, and the physical components of HRQOL after chemotherapy compared with before chemotherapy. The HRQOL scores correlated significantly with yang-deficiency, Yin-deficiency, and the blood stasis pattern scores. A generalized estimating equation model showed that the HRQOL scores were significantly worse after chemotherapy compared with before chemotherapy for the physical component, but not for the mental component. Blood stasis pattern was significantly associated with a decreased HRQOL in both the physical and mental components. A hemoglobin level yang-deficiency, Yin-deficiency,and blood stasis patterns were all associated with lower HRQOLincancerpatientsafterchemotherapy.

BACKGROUND Bariatric surgery is an efficient strategy for body weight and type 2 diabetes mellitus(T2 DM) management. Abnormal lipid deposition in visceral organs,especially the pancreas and liver, might cause beta-cell dysfunction and insulin resistance. Extracellular matrix(ECM) remodeling allows adipose expansion, and matrix metalloproteinases(MMPs) play essential roles in ECM ***-2 and MMP-9 are the substrates of MMP-7. Different studies have reported that MMP-2,-7, and-9 increase in patients with obesity and metabolic syndromes or T2 DM and are considered biomarkers in obesity and hyperglycemia *** prospectively investigate whether MMP-2, MMP-7, and MMP-9 differ after two bariatric surgeries: Gastric bypass(GB) and sleeve gastrectomy(SG).METHODS We performed GB in 23 and SG in 19 obese patients with T2 DM. We measured body weight, waist circumference, body mass index(BMI), and serum concentrations of total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, fasting blood sugar(FBS),hemoglobin A1 c(Hb A1 c), C-peptide, homeostasis model assessments of insulin resistance, and MMP-2, MMP-7, and MMP-9 levels at baseline and at 3, 12, and 24 mo *** Twenty-three patients aged 44.7 ± 9.7 years underwent GB, and 19 patients aged40.1 ± 9.1 years underwent SG. In the GB group, BMI decreased from 30.3 ± 3.4 to24.4 ± 2.4 kg/m2, Hb A1 c decreased from 9.2% ± 1.5% to 6.7% ± 1.4%, and FBS decreased from 171.6 ± 65.0 mg/d L to 117.7 ± 37.5 mg/d L 2 years post-operation(P < 0.001). However, the MMP-2, MMP-7, and MMP-9 levels pre-and post-GB were similar even 2 years post-operation(P = 0.107, 0.258, and 0.466,respectively). The SG group revealed similar results: BMI decreased from 36.2 ±5.1 to 26.9 ± 4.7 kg/m2, Hb A1 c decreased from 7.9% ± 1.7% to 5.8% ± 0.6%, and FBS decreased from 138.3 ± 55.6 mg/d L to 95.1 ± 3.1 mg/d L(P < 0.001).

OBJECTIVE: To examine and describe the use of Western and Chinese Medicine for pregnancy preparation among women with breast cancer after cancer-related treatment in ***: Women of reproductive age(20-49years) women who were treated for breast cancer from January 2011 through June 2015 in a Taiwan Residents city participated in the study. Of 306 eligible study participants, interviews were completed in197(64%). Participants were asked about sociodemographic variables, disease and treatment characteristics, their desire for fertility, and their use of Western or Chinese ***: The proportions of women who planned to use Western or Chinese Medicine to help achieve pregnancy were 17.3% and 14.7%, respectively. The result of binary logistic regression showed that current employment and lack of children were factors predictive of the use of Western Medicine. Younger age and the use of Chinese Medicine before treatment were predictors of using Chinese Medicine. While the desire for fertility preservation was related to the use of Western Medicine,the desire for pregnancy was related to the use of Chinese ***: Various characteristics guided the women's decisions to use Western or Chinese Medicine. Health care providers should learn patients' preferences for fertility preservation and provide appropriate advice, referring them to safe providers of their desired method of fertility treatment.

4-tert-butylstyrene-EPDM-divinylbenzene graft terpolymer (PBED) was prepared by graft cross-polymerization in toluene using BPO as an initiator. The gel-PBED and solPBED were isolated from extraction of tetrahydrofuran (THF), and then they were identified by IR spectroscopy. The maximum oil-absorptivity of gel-PBED produced from the optinum reaction conditions was 8 420% but its swelling rate was very low. The highest oil-absorptivity of photocrosslinked sol-PBED film was 5 800%. Although its oil absorbency was not as high as gel-PBED' s, swelling rate was higher than that of gelPBED and was suitable for commercial purpose. After swelling in oil, neither gel PBED nor photocrosslinked sol-PBED film having high oil-absorptivity had sufficient mechanical strength to be taken out of oil wholly. As is known, composite technique is one of the useful methods for reinforcing them. Fibers, sponges and non-woven cloths were used as reinforcers or supporters in this work. Oil-absorptivities and swelling kinetics were evaluated by method ASTM (F726 - 81 ) and an experimental equation. The mechanical properties and the morphologies of some composites were measured by tensile tester and SEM , respectively.

广西的大明山历史上其名称曾经有过多次的变迁:壮语名字叫"Byacwx",为祖山、灵山的意思。汉文文献记载的大明山,古称A天之山、博邪山、镆钅耶山、五峰山、大鸣山、大名山、大冥山等。历史归属和称呼的多次变迁并无损于大明山文明的发展,反而给予了大明山本身蕴含有某种历史魅力,无疑也增加了这座大山对世人的诱惑。
