| 7 | Current status of endoscopic retrograde cholangiopancreatography in patients with surgically altered anatomy显示文摘Endoscopic retrograde cholangiopancreatography(ERCP)in patients with surgically altered anatomy must be performed by a highly experienced endoscopist.The challenges are accessing the afferent limb in different types of reconstruction,cannulating a papilla with a reverse orientation,and performing therapeutic interventions with uncommon endoscopic accessories.The development of endoscopic techniques has led to higher success rates in this group of patients.Device-assisted ERCP is the endoscopic procedure of choice for high success rates in short-limb reconstruction;however,these success rate is lower in long-limb reconstruction.ERCP assisted by endoscopic ultrasonography is now popular because it can be performed independent of the limb length;however,it must be performed by a highly experienced and skilled endoscopist.Stent deployment and small stone removal can be performed immediately after ERCP assisted by endoscopic ultrasonography,but the second session is needed for other difficult procedures such as cholangioscopy-guided electrohydraulic lithotripsy.Laparoscopic-assisted ERCP has an almost 100%success rate in longlimb reconstruction because of the use of a conventional side-view duodenoscope,which is compatible with standard accessories.This requires cooperation between the surgeon and endoscopist and is suitable in urgent situations requiring concomitant cholecystectomy.This review focuses on the advantages,disadvantages,and outcomes of various procedures that are suitable in different situations and reconstruction types.Emerging new techniques and their outcomes are also discussed. | Chonlada Krutsri Mitsuhiro Kida Hiroshi Yamauchi Tomohisa Iwai Hiroshi Imaizumi Wasaburo Koizumi | 2019 | World Journal of Gastroenterology2019，25，26： | 23 |
| 8 | 不同剂量全身糖皮质激素对重度慢阻肺合并肺部感染患者血糖的影响显示文摘目的探讨不同剂量的全身糖皮质激素对慢阻肺患者血糖的影响。方法入选慢阻肺者按平均每天糖皮质激素总量分为低剂量组(A组)87例、中剂量组(B组)81例、高剂量组(C组)80例,检测其血糖水平,比较各组之间高血糖事件的发生率及出现高血糖时间的差异,并将中、高剂量组高血糖事件患者中血糖值与CPIS评分、APACHE II评分进行相关性分析。结果不同剂量组之间高血糖事件的发生率有差异,低、中剂量组较高剂量组出现高血糖时间长;中、高剂量组高血糖事件患者中血糖值与CPIS评分、APACHE Ⅱ评分值存在正相关。结论不同剂量的糖皮质激素的慢阻肺患者的高血糖事件发生率及出现高血糖的时间会有所不同,激素诱导高血糖的慢阻肺患者的高血糖与其生理健康状况及感染有一定的关系。 | 肖靖华 陈子盛 陈卫萍 田东波 廖小雯 张亦飞 | 2017 | 临床肺科杂志2017，22，9： | 21 |
| 9 | 简支梁-CRTSⅡ型板式无砟轨道制动力传递规律显示文摘为研究制动力作用下高速铁路简支梁桥与CRTSⅡ型板式无砟轨道的相互作用问题,以沪昆高铁上某12×32m双线简支箱梁为工程背景,建立考虑钢轨-轨道板-底座板-梁体-墩台的一体化有限元模型,系统分析单线制动和双线同向制动工况下轨道和桥梁结构的受力及变形规律。研究结果表明:钢轨制动力及位移对加载位置极为敏感,检算时应考虑多种荷载位置的影响;单线制动作用下钢轨与轨道板相对位移、CA砂浆剪切位移、桥梁和底座板相对位移均处于弹性范围内;当车辆在桥上靠近桥台处制动时,摩擦板可有效地减少传递至路基段的纵向力;双线同向制动作用下各项效应与单线制动有载侧趋势相同,桥梁和底座板将发生相对滑动。 | 朱乾坤 戴公连 闫斌 | 2014 | 铁道科学与工程学报2014，11，6： | 17 |

| 11 | Diagnostic value of gamma-glutamyltransferase/aspartate aminotransferase ratio, protein induced by vitamin K absence or antagonist II, and alpha-fetoprotein in hepatitis B virus-related hepatocellular carcinoma显示文摘BACKGROUND Researchers have investigated the diagnostic value of protein induced by vitamin K absence or antagonist II (PIVKA-II) and alpha-fetoprotein (AFP) in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC), and obtained abundant clinical diagnostic data. However, PIVKA-II and AFP have unsatisfactory specificity and sensitivity in the diagnosis of early-stage HBV-related HCC. Gamma-glutamyltransferase (γ-GT) and aspartate aminotransferase (AST) are common biomarkers for evaluating liver function, and we hypothesized that the γ-GT/AST ratio in combination with PIVKA-II and AFP would improve the diagnosis of early-stage HBV-related HCC. AIM To evaluate the diagnostic value of γ-GT/AST ratio alone or in combination with PIVKA-II and AFP in HBV-related HCC. METHODS Serum levels of γ-GT, AST, PIVKA-II, and AFP were detected and analysed in 176 patients with HBV-related HCC and in 359 patients with chronic hepatitis B. According to tumour size and serum level of HBV DNA, HBV-related HCC patients were divided into the following categories: Early-stage HCC patients, HCC patients, HBV DNA positive (HBV DNA+) HCC patients, and HBV DNA negative (HBV DNA-) HCC patients. Receiver-operating characteristic (ROC) curves were used to analyse and compare the diagnostic value of the single and combined detection of various biomarkers in different types of HBV-related HCC. RESULTS Tumour size was positively correlated with serum levels of PIVKA-II and AFP in HCC patients (r = 0.529, aP < 0.001 and r = 0.270, bP < 0.001, respectively), but there was no correlation between tumour size and the γ-GT/AST ratio (r = 0.073, P = 0.336). The areas under the receiver-operating characteristic curves (AUROCs) of the γ-GT/AST ratio in early-stage HCC patients, HBV DNA+ HCC patients and HBV DNA- HCC patients were not significantly different from that in the total HCC patients (0.754, 0.802, and 0.705 vs 0.779, respectively;P > 0.05). When PIVKA-II was combined with the γ-GT/AST ratio in the diagnosis of earlystage HCC, HCC, and HBV DNA+ HCC, the AUROCs of PIVKA-II increased, with values of 0.857 vs 0.835, 0.925 vs 0.913, and 0.958 vs 0.954, respectively. When AFP was combined with the γ-GT/AST ratio in the diagnosis of early-stage HCC, HCC, HBV DNA+ HCC, and HBV DNA- HCC, the AUROCs of AFP increased, with values of 0.757 vs 0.621, 0.837 vs 0.744, 0.868 vs 0.757, and 0.840 vs 0.828, respectively. CONCLUSION The γ-GT/AST ratio may be better than PIVKA-II and AFP in the diagnosis of early-stage HBV-related HCC, and its combination with PIVKA-II and AFP can improve the diagnostic value for HBV-related HCC. | Qiang Wang Qi Chen Xia Zhang Xiao-Lan Lu Qin Du Tao Zhu Guo-Yuan Zhang Dong-Sheng Wang Qu-Ming Fan | 2019 | World Journal of Gastroenterology2019，25，36： | 17 |

| 18 | A MODIFIED PROJECTION AND CONTRACTION METHOD FOR A CLASS OF LINEAR COMPLEMENTARITY PROBLEMS显示文摘Recently, we have proposed an iterative projection and contraction (PC) method for a class of linear complementarity problems (LCP)[4]. The method was showedto be globally convergent, but no statement could be made about the rate of con-vergence. In this paper, we develop a modified globally linearly convergent PCmethod for linear complementarity problems. Both the method and the convergence proofs are very simple. The method call also be used to solve some linearvariational inequalities. Several computational experiments are presented to indi-cate that the method is surprising good for solving some known difficult problems. | B.S.

| 20 | Ocular surface changes in type II diabetic patients with proliferative diabetic retinopathy显示文摘AIM: To detect and analyze the changes on ocular surface and tear function in type II diabetic patients with proliferative diabetic retinopathy(PDR), an advanced stage of diabetic retinopathy(DR), using conventional ophthalmic tests and the high-resolution laser scanning confocal microscopy.METHODS: Fifty-eight patients with type II diabetes were selected. Based on the diagnostic criteria and stage classification of DR, the patients were divided into the non-DR(NDR) group and the PDR group. Thirty-six patients with cataract but no other ocular and systemic disease were included as non-diabetic controls. All the patients were subjected to the conventional clinical tests of corneal sensitivity, Schirmer I test, and corneal fluorescein staining. The non-invasive tear film break-up time(NIBUT) and tear interferometry were conducted by a Tearscope Plus. The morphology of corneal epithelia and nerve fibers was examined using the high-resolution confocal microscopy.RESULTS: The NDR group exhibited significantly declined corneal sensitivity and Schirmer I test value, as compared to the non-diabetic controls(P <0.001). The PDR group showed significantly reduced corneal sensitivity, Schirmer I test value, and NIBUT in comparison to the non-diabetic controls(P <0.001).Corneal fluorescein staining revealed the progressively injured corneal epithelia in the PDR patients. Moreover,significant decrease in the corneal epithelial density andmorphological abnormalities in the corneal epithelia and nerve fibers were also observed in the PDR patients.CONCLUSION: Ocular surface changes, including blunted corneal sensitivity, reduced tear secretion, tear film dysfunction, progressive loss of corneal epithelia and degeneration of nerve fibers, are common in type II diabetic patients, particularly in the diabetic patients with PDR. The corneal sensitivity, fluorescein staining scores,and the density of corneal epithelial cells and nerve fibers in the diabetic patients correlate with the duration of diabetes. Therefore, ocular surface of the patients with PDR should be examined regularly by conventional approaches and confocal microscopy to facilitate early diagnosis and treatment of keratopathy. | Yan Gao Yan Zhang Yu-Sha Ru Xiao-Wu Wang Ji-Zhong Yang Chun-Hui Li Hong-Xing Wang Xiao-Rong Li Bing Li | 2015 | International Journal of Ophthalmology(English edition)2015，8，2： | 11 |
