*** The Altay Orogenic Belt in Xinjiang,China is located in the west of the Central Asian Orogenic Belt and in the transition zone between the Siberian Plate and the Kazakhstan-junggar Plate,extending approximately 500 km in northern Xinjiang,China(Fig.1a).The Altay Orogenic Belt has undergone two-way accretion of the Paleozoic crust and the Meso-Cenozoic intracontinental orogeny,leading to the formation of large numbers of intermediate-acid *** than 100000 pegmatite veins have been discovered in the intermediate-acid intrusions,and they constitute an important rare metal metallogenic belt of China(Fig.1b).

A novel and efficient method was developed for the liquid-phase synthesis of Nj,4-disubstitutedbenzodiazepine-2,5-diones with 2-chloro-5-nitrobenzoic acid as initiating material via 4 step reactions containing esterifieation, ＂Ulmn reaction＂, acylation, alkylation and cyclization. The reaction conditions were mild and the overall yields of the products ranged from 45% to 71%.

AIM: To determine the relationship between CD11 c expression level and prognosis in patients with gastric cancer(GC).METHODS: This retrospective survival study was performed from July 31,2008 to june 30,2014. Our study inclusion criteria included all the patients with GC who underwent surgical resection between January 1998 and December 2009 in the Third Affiliated Hospital of Soochow University. CD11 c expression levels in 140 patients with GC at different UICC stages were evaluated using immunohistochemistry,and GC tissues from 16 cases were further verified by q RTPCR. The χ2 test was used to compare the patientand disease-related factors between the low CD11 c expression group and the high expression group. Univariate probabilities of overall survival(OS) and disease-free survival(DFS) were assessed using the Kaplan-Meier method. The log rank test was used to compare survival curves. Different multivariate COX models were used to estimate the association between CD11 c expression and both death and recurrence riskin GC ***: The average CD11 c expression level was 5.1 ± 1.8/high power field(HPF) in 10 gastritis samples,4.5 ± 2.3/HPF in 10 gastric polyp samples and 9.7 ± 6.3/HPF in 140 gastric cancer samples,respectively. The CD11 c expression level was significantly decreased from UICC stage Ⅰ to stage Ⅳ(stage Ⅰ: 16.0 ± 7.4,stage Ⅱ: 10.4 ± 5.5,stage Ⅲ: 9.4 ± 6.1,stage Ⅳ: 5.3 ± 3.2,P < 0.001). Patients in the high CD11 c expression group had a greater 3- and 5-year OS probability and longer median survival time compared with the low CD11 c expression group,(67.7% vs 39.2%; 51.4% vs 29.0%; 67.0 mo vs 28.0 mo; χ2 = 6.80,P = 0.009),and had a greater 3- and 5-year DFS probability and longer median DFS time(63.7% vs 24.0%; 49.1% vs 11.9%; 64.0 mo vs 18.0 mo; χ2 = 15.39,P < 0.001). Patients with high CD11 c high expression had a reduced risk of death(HR = 0.56,95%CI: 0.33-0.98,P < 0.05) and relapse(HR = 0.39,95%CI: 0.23-0.67,P < 0.01) compared with patients

Objective NaFeEDTA was considered as a promising iron fortificant for controlling iron deficiency anemia. Soy sauce is a suitable food carder for iron fortification and is a popular condiment in China. Iron absorption rates of NaFeEDTA and FeSO4 were observed and compared in adult female subjects. Methods The stable isotope tracer method was used in Chinese females consuming a typical Chinese diet. Ten healthy young Chinese women were selected as subjects in the 15-day study. A plant-based diet was used based on the dietary pattern of adult women in the 1992 National Nutrition Survey. Six milligram of 54Fe in 54FeSO4 soy sauce and 3 mg 5SFe in NaSSFeEDTA soy sauce were given to the same subjects in two days. Food samples and fecal samples were collected and analyzed. Results Iron absorption rates of NaFeEDTA and FeSO4 were 10.51%：~：2.83 and 4.73%＋2.15 respectively. The 5SFe （NaFeEDTA） absorption was significantly higher than that of 54Fe （FeSO4）（P〈0.01）. The iron absorption rate from NaFeEDTA was 1.2 times higher than that from FeSO4 in Chinese adult women consuming a typical Chinese diet. Conclusion The higher absorption rate of NaFeEDTA suggested that NaFeEDTA would be a better iron fortificant used in soy sauce for the controlling of iron deficiency anemia in China.
