HFRS(HIAF FRagment Separator) will be the radioactive secondary beam separation line on High-Intensity heavy-ion Accelerator Facility(HIAF) in China. Several TPC detectors, with high count rates, are planned for particle identification and beam monitoring at HFRS. This paper presents an event-driven internal memory and synchronous readout(EDIMS)prototype ASIC chip. The aim is to provide HFRS-TPC with high-precision time and charge measurements with high count rates and a large dynamic range. The first prototype EDIMS chip integrated 16 channels and is fabricated using a 0.18-μm CMOS process. Each channel consists of a charge-sensitive amplifier, fast shaper, slow shaper, peak detect-and-hold circuit, discriminator with time-walk compensation, analog memory, and FIFO. The token ring is used for clock-synchronous readout. The chip is taped and tested.

Background： In Sus scrofa, methionine sulfoxide reductase B3（MSRB3） is a crucial candidate gene for ear size, and an important conformational trait of pig breeds. However, challenges in MSRB3 c DNA amplification have prevented further identification of MSRB3 allelic variants influencing pig ear ***： We cloned a full-length c DNA sequence of porcine MSRB3 by rapid-amplification of c DNA ends. The3,765-bp gene contained a 5＇-untranslated region（UTR）（190 bp）, a coding region（552 bp）, and a 3＇-UTR（3,016 bp） and shared 84 %, 84 %, 87 %, 86 %, and 70 % sequence identities with human, orangutan, mouse, chicken, and zebrafish,respectively. The gene encoded a 183-amino acid protein, which shared 88 %, 91 %, 89 %, 86 %, and 67 % identities with human, orangutan, mouse, chicken, and zebrafish, respectively. Tissue expression analysis using q RT-PCR revealed that MSRB3 was expressed in the heart, liver, lung, kidney, spleen, ear, muscle, fat, lymph, skeletal, and hypothalamic tissues. Three single nucleotide polymorphisms（SNPs） were identified in MSRB3： c.-735 C 〉 T in the 5＇ flanking region,c.2571 T 〉 C in the 3＇-UTR, and a synonymous mutation of c.484 T 〉 C in the coding region. The SNPs c.-735 C 〉 T and c.2571 T 〉 C were significantly associated with ear size in a Large White × Minzhu F2 population other than in Beijing Black pigs. Subsequently, at SNP c.-735 C 〉 T, the m RNA of MSRB3 was significantly higher expressed in ears of individuals with the TT genotype（Minzhu） than those with CC（Large White）.Conclusions： The porcine MSRB3 owned a 3,765-bp full-length c DNA sequence and was detected to express in ear tissue. Two SNPs of this gene were shown to be significantly associated with ear size in a Large White × Minzhu intercross population instead of Beijing Black pig population. What＇s more, the individuals with higher m RNA expression of MSRB3 have larger ear sizes. These results provide useful information for further functional analyses of MSRB3 influencing ear

Oxidation of ethylbenzene, n-propylbcnzene and n-butylbenzene gives the corresponding ketones and alcohols in good yields by organic polymer supported low—valent Ru (Ⅱ) complexes under 1 atm. of air or oxygen at 100℃ in the absence of solvent. The calalytic selectivity to total ketone and alcohol ranged from 98.7％ to 100％. The polymer complex polymer—bipy—Ru—bipy (bipy=2, 2'—bipyridine) is very stable and can be reused for 5 times (each for 5h) without appreciable change in catalytic activity.

Background： Primary anti-neutrophil cytoplasmic antibody-associated vasculitis （AAV） is a chronic autoimmune disease associated with multisystem dysfunction. Renal involvement is common and closely associated with outcome. The purpose of this study was to investigate the clinical determinants of mortality of patients with AAV-related renal injury in the first 2 years after diagnosis in a single West Chinese center. Methods： Demographic and laboratory parameters of 123 consecutive patients with AAV-related renal injury diagnosed in Renal Division and Institute ofNephrology, Sichuan Provincial People＇s Hospital between 2004 and 2012 were collected retrospectively. All patients were followed up for 2 years after diagnosis. Survivors were compared with nonsurvivors to identify the clinical baseline variables associated with mortality. Multivariate Cox regression model was used to determine the independent predictors of mortality. Results： Of the 123 patients, 46 （37.4%） died by the end of 2 years after diagnosis, with 41 （33.3%） patients dying within the first 12 months. In comparison with the survivors, Birmingham Vasculitis Activity Score （BVAS）, the incidence of pulmonary hemorrhage and digestive system （DS） involvement, serum creatinine, and erythrocyte sedimentation rate were significantly higher in nonsurvivors, whereas lymphocyte counts, hemoglobin, and complement 3 （C3） were significantly lower. Renal replacement therapy was more common in nonsurvivors. High BVAS （hazard ratio [HR] = 1.058, 95% confidence interval [CI]： 1.002-1. I17; P = 0.042）, pulmonary hemorrhage （MR = 1.970, 95% CI： 1.033-3.757; P = 0.04）, DS involvement （HR = 2.911,95% （7：1.212-6.911 ： P = 0.017）4 and serum creatinine 〉400 μmol/L （MR = 2.910, 95% CI： 1.271-6.664, P = 0.012） were independent predictors of death in patients with AAV-related renal injury. Conclusions： Patients with AAV-related renal injury have high early mortality. Those with high BVAS （particularly with pulmonary or DS invol

骨质疏松症是慢性肾脏病(chronic kidney disease,CKD)的合并症或并发症。低骨密度、骨质疏松症及骨折是CKD患者预后不良的风险因素,积极防治CKD患者骨质疏松症至关重要。地舒单抗是靶向核因子κB受体活化因子配体的全人源单克隆抗体,不经肾脏代谢或排泄。临床研究表明,不同阶段CKD(包括透析、肾移植)合并骨质疏松症患者使用地舒单抗后可增加骨密度,降低骨折风险,安全性良好。需要注意的是,CKD患者发生低钙血症的风险较高,在使用地舒单抗之前,需要密切监测并提前补充钙和维生素D,在治疗期间需要监测血钙水平。该文就地舒单抗在CKD患者的骨保护作用研究进展作一综述。

Although quantitative trait loci（QTLs） for number of thoracic-lumbar vertebrae have been identified on Sus scrofa chromosomes（SSCs） 1 and 7, the influence of these QTLs on the thoracic and lumbar vertebrae is not clear. The aim of this study was to identify single nucleotide polymorphisms（SNPs） associated with total number of thoracic-lumbar vertebrae and for each trait（number of thoracic and lumbar vertebrae） separately. A total of 581 individuals from an F2 Large White×Minzhu population were genotyped using an SNP60 K chip. Performing a genome-wide association study（GWAS） for total number of thoracic-lumbar vertebrae, 38 significant SNPs were identified in two QTL regions located on SSC1 and SSC7. Performing a GWAS for number of thoracic vertebrae only, 72 significant SNPs were located on SSC7. While performing a GWAS for number of lumbar vertebrae only, 17 significant SNPs were identified on SSC1. Gene mining suggested that the gene encoding orphan nuclear receptor, germ cell nuclear factor（NR6A1） on SSC1 was a strong candidate affecting the number of lumbar vertebrae in pigs. Additionally, genes encoding vertnin（VRTN）, prospero homeobox 2（PROX2）, Finkel-Biskis-Jinkins murine osteosarcoma viral oncogene homolog（FOS）, and transforming growth factor beta 3（TGFB3） may be important candidates affecting the number of thoracic vertebrae in pigs. QTLs on SSC1 and SSC7 independently influenced the numbers of thoracic and lumbar vertebrae. These results shed light on the complex genetic background of vertebrae development in pigs.
