| 2 | 末次盛冰期和全新世大暖期毛乌素沙地的空间变化显示文摘沙漠/沙地边缘和内部的古风成沙层、砂质古土壤是重建晚第四纪以来地表变化的直接地质证据。位于我国北方半干旱区的毛乌素沙地,其地表过程对气候变化响应敏感。在对毛乌素沙地进行野外拉网式调查以及前人研究的基础上,我们在沙地南部和东部的沙漠-黄土过渡带发现了大量的埋藏古风成沙丘沉积,指示了干冷期沙漠扩张的最南、东界限;沙地内部广泛发育的砂质古土壤则表明在气候相对暖湿期地表植被生长,土壤发育,沙丘基本被固定。对14个典型风成沙/黄土/古土壤沉积剖面进行了光释光年代学样品的采集和测试,结合空间分析和他人研究结果,发现在末次盛冰期(约26~16ka),毛乌素沙地的流动沙丘向南、东扩张,扩张距离现代边界约30~50km,面积扩大至少约10000km^2,占现代沙地面积的25%;在全新世大暖期(约9~5ka),毛乌索沙地大部分被固定,发育了较厚的砂质古土壤。研究结果揭示了毛乌素沙地的地表过程对末次盛冰期和全新世大暖期气候变化的直接响应。 | 徐志伟 鹿化煜 弋双文 周亚利 Joseph A Mason 王晓勇 陈英勇 朱芳莹 张瀚之 翟秀敏 | 2013 | 第四纪研究2013,33,2: | 30 |
| 3 | Proposal of an ultrasonographic classification for hepatic alveolar echinococcosis: Echinococcosis multilocularis Ulm classification-ultrasound显示文摘AIM: To establish an ultrasonographic classification based on a large sample of patients with confirmed hepatic alveolar echinococcosis(AE).METHODS: Clinical data and ultrasonography(US) findings of 185 patients(100 males; 85 females; mean age at diagnosis: 51.4 ± 17.6 years; mean age at time of US examination: 58.7 ± 18.2 years) were retrospectively reviewed with respect to the US morphology of hepatic AE lesions. The sonomorphological findings were grouped according to a five-part classification scheme.RESULTS: Application of the new classification resulted in the following distribution of sonomorphological patterns among the patients examined: hailstorm(54.1%); pseudocystic(13.5%); ossification(13.0%); hemangioma-like(8.1%); and metastasis-like(6.5%). Only 4.9% of lesions could not be assigned to a sonomorphological pattern.CONCLUSION: The sonomorphological classification proposed in the present study facilitates the diagnosis,interpretation and comparison of hepatic alveolar echinococcosis in routine practice and in the context of scientific studies. | Wolfgang Kratzer Beate Gruener Tanja EM Kaltenbach Sarina Ansari-Bitzenberger Peter Kern Michael Fuchs Richard A Mason Thomas FE Barth Mark M Haenle Andreas Hillenbrand Suemeyra Oeztuerk Tilmann Graeter | 2015 | World Journal of Gastroenterology2015,21,43: | 16 |
| 4 | Complications associated with prone positioning in elective spinal surgery显示文摘Complications associated with prone surgical positioning during elective spine surgery have the potential to cause serious patient morbidity.Although many ofthese complications remain uncommon,the range of possible morbidities is wide and includes multiple organ systems.Perioperative visual loss(POVL)is a well described,but uncommon complication that may occur due to ischemia to the optic nerve,retina,or cerebral cortex.Closed-angle glaucoma and amaurosis have been reported as additional etiologies for vision loss following spinal surgery.Peripheral nerve injuries,such as those caused by prolonged traction to the brachial plexus,are more commonly encountered postoperative events.Myocutaneous complications including pressure ulcers and compartment syndrome may also occur after prone positioning,albeit rarely.Other uncommon positioning complications such as tongue swelling resulting in airway compromise,femoral artery ischemia,and avascular necrosis of the femoral head have also been reported.Many of these are well-understood and largely avoidable through thoughtful attention to detail.Other complications,such as POVL,remain incompletely understood and thus more difficult to predict or prevent.Here,the current literature on the complications of prone positioning for spine surgery is reviewed to increase awareness of the spectrum of potential complications and to inform spine surgeons of strategies to minimize the risk of prone patient morbidity. | J Mason De Passe Mark A Palumbo Maahir Haque Craig P Eberson Alan H Daniels | 2015 | World Journal of Orthopedics2015,6,3: | 7 |

| 6 | Parameters affecting different acoustic radiation force impulse applications in the diagnosis of fibrotic liver changes显示文摘AIM: To analyze the virtual touch tissue quantification(VTTQ) and virtual touch imaging quantification(VTIQ) techniques, and identify possible factors that may influence VTTQ and VTIQ measurements.METHODS: One hundred and eighty-six(104 women/82 men) of 323 subjects met the inclusion criteria(age > 18 years, no history of chronic or gastrointestinal disease, body-mass index(BMI) < 30 kg/m2, a fasting period of at least three hours, no history of hepatotoxic pharmaceuticals, alcohol consumption < 24 g/d in men and < 12 g/d in women, and normal findings upon ultrasound examination of the abdomen). Measurements were taken at depths of 50 mm with VTTQ, 15 mm and 25 mm with VTIQ in the right hepatic lobe, and at 15 mm with only VTIQ in the left hepatic lobe. The examiner acquired six measurements per position, thereby giving 24 measurements in total.RESULTS: The 95% confidence intervals of mean were1.23-1.29 m/s for VTTQ and 1.29-1.37 m/s, 1.17-1.23 m/s, and 1.48-1.57 m/s for VTIQ in a depth of 15 mm and 25 mm in the right hepatic lobe and 15 mm in the left hepatic lobe. Only superficial measurements in the right hepatic lobe with the VTIQ method exhibited an effect of age on shear wave velocity. Measurements acquired using the 6C1 probe with the VTTQ method showed no dependence on BMI. By comparison, BMI influenced measurements taken with the VTIQ method using the 9L4 probe in the superficial and deep areas of the right hepatic lobe, as well as in the left hepatic lobe(P = 0.0160, P = 0.0019, P = 0.0173, respectively). Gender influenced measurements at depths of 50 mm with VTTQ and 25 mm with VTIQ in the right hepatic lobe(P = 0.0001, P = 0.0269). Significant differences were found between measurements with the 6C1(VTTQ) and 9L4 probes(VTIQ)(P = 0.0067), between superficial and deep measurements(P < 0.0001), and between the right and left lobes of the liver(P < 0.0001). CONCLUSION: Measurements in the right lobe and deep regions are preferable. Gender differences must be considered. BMI must be considered when assessing VTIQ technology. | Sabrina Galgenmueller Heike Jaeger Wolfgang Kratzer Stefan A Schmidt Suemeyra Oeztuerk Mark M Haenle Richard A Mason Tilmann Graeter | 2015 | World Journal of Gastroenterology2015,21,27: | 5 |

| 9 | Prevalence of cholelithiasis in patients with chronic inflammatory bowel disease显示文摘AIM: To investigate the effect of chronic inflammatory bowel disease (CIBD) specific risk factors for cholecystolithiasis,as duration and involvement pattern of the disease and prior surgery in patients with Crohn's disease (CD) and ulcerative colitis (UC).METHODS: A total of 222 patients with CD (135 females,87 males; average age, 35.8±11.8 years; range 17-81 years)and 88 patients with UC (39 females, 49 males; average age, 37.2±13.6 years; range 16-81 years) underwent clinical and ultrasound examinations. Besides age, sex and degree of obesity, patients' CIBD specific parameters, including duration and extent of disease and prior operations were documented and evaluated statistically using logistic regression.RESULTS: The overall prevalence of gallbladder stone disease in patients with CD was 13% (n = 30). Only age could be shown to be an independent risk factor (P = 0.014).Compared to a collective representative for the general population in the same geographic region, the prevalence of cholecystolithiasis was higher in all corresponding age groups. Patients with UC showed an overall prevalence of gallbladder stone disease of only 4.6%.CONCLUSION:Only age but not disease-specific factors such as duration and extent of disease, and prior surgery are independent risk factors for the development of cholecystolithiasis in patients with CIBD. | Wolfgang Kratzer Mark M Haenle Richard A Mason Christian von Tirpitz Volker Kaechele | 2005 | World Journal of Gastroenterology2005,11,39: | 3 |

| 12 | Sand dunes as potential sources of dust in northern China显示文摘While saltation bombardment of sand grains on a fine substrate can produce considerable dust, the well-sorted nature of sand dunes tends to preclude them from consideration as major dust sources. Recent research, however, has revealed that sand dunes can, in some cases, be large sources of dust. We used the PI-SWERL(Portable In-Situ Wind Erosion Laboratory) to measure in the field the potential of sand dunes and other desert landforms to emit particulate matter <10 μm(PM-10) dust in the Tengger, Ulan Buh, and Mu Us deserts of northern China. Combined with high resolution particle size measurements of the dune sand, an assessment of sand dunes as a dust source can be made. Large active transverse dunes tend to contain little to no stored PM-10, yet they produce a low dust flux. Coppice dunes stabilized by vegetation contain appreciable PM-10 and have very high dust emission potential. There is a positive correlation between the amount of PM-10 stored in a dune and its potential dust flux. Saltation liberates loose fines stored in dunes, making them very efficient dust emitters compared to landforms such as dry lake beds and washes where dust particles are unavailable for aeolian transport due to protective crusts or sediment cohesion. In cases where large dunes do not store PM-10 yet emit dust when active, two hypotheses can be considered:(1) iron-oxide grain coatings are removed during saltation, creating dust, and(2) sand grains collide during saltation, abrading grains to create dust. Observations reveal that iron oxide coatings are present on some dune sands. PI-SWERL data suggests that low dust fluxes from dunes containing no stored dust may represent an estimate for the amount of PM-10 dust produced by removal of iron oxide coatings. These results are similar to results from dunes in the United States. In addition, PI-SWERL results suggest that dust-bearing coppice dunes, which cover vast areas of China's sandy deserts, may become major sources of dust in the future if overgrazing, depletion of groundwater, or drought destabilizes the vegetation that now partially covers these dunes. | Mark R SWEENEY LU HuaYu CUI MengChun Joseph A MASON FENG Han XU ZhiWei | 2016 | Science China Earth Sciences2016,59,4: | 2 |
