The aggregation behavior and structure of hydrophobically modified block copolymers of acrylamide and 2-phenoxylethylacrylate were investigated by viscometry, 1H NMR relaxation, 2D NOESY, fluorescence and dynamic light scattering. It Was found that the aggregation behavior was strongly dependent on the concentration of polymer solution and the hydrophobe contents. With varying concentration from 2.0, 6.0, 8.0 to 12.0 g/L, there were different aggregate morphologies distributed in aqueous solutions, such as monopolymer chain, micelle-like aggregate, multi-micelle aggregate and cross-linked network. According to the model of aggregation, it can give a reasonable explanation on the large magnitude enhancement of viscosity with the increasing of polymer concentration. Additional data of 2D NOESY and fluorescence show that the copolymer with higher hydrophobe content（molar fraction≥ 1%） is likely to form intra-molecular association.

Researches and applications of Geographic Information Systems (GIS) in China started in the early 1980s. In the early period, the development of GIS was mainly depended on the progress and applications of remote sensing, aerial photography, as well as computer aided design (CAD). In recent years, with the development of Global positioning System(GpS) and Internet technology, GIS has being developed vigorously in the county. Looking ahead to the 21st century, a new era of “Digital Earth” and “Cyberspace” is coming, which will provide a great opportunity as well as a challenge to the China’s GIS circles.

AIM: To compare the efficacy and safety of acellular dermal matrix (ADM) bioprosthetic material and endorectal advancement flap (erAF) in treatment of complex anorectal fistula. METHODS: Ninety consecutive patients with complex anorectal fistulae admitted to Anorectal Surgical Department of First Affi liated Hospital, Xinjiang Medical University from March 2008 to July 2009, were enrolled in this study. Complex anorectal fistula was diagnosed following its clinical, radiographic, or endoscopic diagnostic criteria. Under spinal anesthesia, patients underwent identification and irrigation of the fistula tracts using hydrogen peroxide. ADM was securely sutured at the secondary opening to the primary opening using absorbable suture. Outcomes of ADM and erAF closure werecompared in terms of success rate, fecal incontinence rate, anorectal deformity rate, postoperative pain time, closure time and life quality score. Success was defined as closure of all external openings, absence of drainage without further intervention, and absence of abscess formation. Follow-up examination was performed 2 d, 2, 4, 6, 12 wk, and 5 mo after surgery, respectively. RESULTS: No patient was lost to follow-up. The overall success rate was 82.22% (37/45) 5.7 mo after surgery. ADM dislodgement occured in 5 patients (11.11%), abscess formation was found in 1 patient, and fistula recurred in 2 patients. Of the 13 patients with recurrent fistula using erAF, 5 (11.11%) received surgical drainage because of abscess formation. The success rate, postoperative pain time and closure time of ADM were significantly higher than those of erAF (p er, no difference was observed in fecal incontinence rate and anorectal deformity rate after treatment with ADM and erAF. CONCLUSION: Closure of fistula tract opening with ADM is an effective procedure for complex anorectal fistula. ADM should be considered a first line treatment for patients with complex anorectal fistula.

In this paper, we assessed the ecological and biodiversity status in the Bohai Sea through a quantitative survey on mac-rofaunal community at 25 stations in Laizhou Bay and adjacent waters in the autumn of *** tested the robustness and effectiveness of taxonomic distinctness as an ecological indictor by analyzing its correlation with species richness and natural environmental variables and by analyzing other ecological indicators (Shannon-Wiener H' and W statistics from Abundance Biomass Comparison curve).Results so obtained indicated that the benthic environment of the study waters in general is not under major impact of anthropogenic disturbance, but some stations in Laizhou Bay and along the coast of the Shandong peninsula and even in the central Bohai Sea might be moderately disturbed and showed signs of ecological *** taxonomic distinctness measures △+ and Λ+ were independent of sampling effort and natural environment factors and were compliant to other ecological *** application of the taxonomic distinctness indicator to assess marine biodiversity and ecosystem health on a larger regional scale with historical data seems promising.

AIM： To investigate the effects of gallbladder stones on motor functions of the gallbladder and the dynamics of bile flow in asymptomatic gallstone disease. METHODS： Quantitative hepatobiliary scintigraphy was performed to detect the parameters of gallbladder motor function [gallbladder ejection fraction （GBEF）, gallbladder visualization time （GBVT）, gallbladder time to peak activity （GBTmax）, gallbladder half emptying time （GBT1/2）, and transit time of bile to duodenum （TTBD）] in 24 patients with asymptomatic cholelithiasis who were diagnosed incidentally during routine abdominal ultrasonographic examination and 20 healthy subjects with normal gallbladder. RESULTS： Even though there was no significant difference in the clinical and laboratory parameters between the patient and control groups, all parameters of gallbladder function except TTBD were found to differ significantly between the two groups. GBEF in the patient group was decreased （p = 0.000） and GBVT, GBT GBT1/2 in the patient group were longer （p = 0.000, p = 0.015, p = 0.001, respectively）.there were not any clinical and laboratory findings, gallbladder filling and emptying could be impaired in patients with gallstone disease.

目的旨在探讨近年引起药物性肝损伤(DILI)的药物和临床特征,识别药物性肝功能衰竭和慢性DILI的危险因素,以便于早期识别和更好地管理。方法对2018年1月至2020年12月期间诊断为DILI并随访至少6个月的224例患者进行回顾性调查和分析。采用单因素和多因素logistic回归分析识别药物性肝功能衰竭和慢性DILI的危险因素。结果中药(占62.5%)包括草药(占中药的84.3%)和一些中成药是研究中发现引起DILI的主要原因。胆汁淤积型与严重和慢性DILI更相关。已存在胆囊疾病、初始总胆红素、初始凝血酶原时间、初始抗核抗体滴度是药物性肝功能衰竭的独立危险因素。碱性磷酸酶(ALp)、丙氨酸转氨酶(ALT)从峰值下降到峰值的50%的时间间隔(T_(0.5ALp)和T_(0.5ALT))延长为慢性DILI的独立危险因素(受试者操作特征曲线下面积=0.787,95%置信区间:0.697~0.878,pp)和T_(0.5ALT)可作为预测慢性DILI的指标。
