Carpal tunnel syndrome （CTS） accompanied by secondary axonal degeneration cannot be clearly dis- criminated using the current cross-validated ultrasound severity classification system. This study aimed at exploring cut-off values of ultrasound parameters, including wrist cross-sectional area （W-CSA）, wrist perimeter （W-P）, ratio of cross-sectional area （R-CSA） and perimeter （R-P）, changes of CSA and P from wrist to one third distal forearm （△CSA＆AP） for differentiation. Seventy-three patients （13 male and 60 female） were assigned into group A （demyelination only, n = 40） and group B （demyelination with secondary axonal degeneration, n = 33） based on the outcomes of nerve conduction studies （NCS）. Receiver Operative Characteristics （ROC） curves were plotted to obtain sensitivity, specificity, and accuracy of cut- off values for all the ultrasound parameters. The overall identified cut-off values （W-CSA 12.0 mm2, W-P 16.27 mm, R-CSA 1.85, R-P 1.48, △CSA 6.98 mm2, △P 5.77 mm） had good sensitivity （77.1-88.6%）, fair specificity （40-62.2%） and fair-to-good accuracy （0.676-0.758）. There were also significant differences in demographics （age and severity gradation, P 〈 0.001）, NCS findings （wrist motor latency and conduction velocity, P 〈 0.0001; wrist motor amplitude, P 〈 0.05; distal sensory latency, P 〈 0.05; sensory amplitude, P 〈 0.001） and ultrasound measurements （W-CSA, W-P, R-CSA, R-P, △CSA＆△P, P 〈 0.05） between groups. These findings suggest that ultrasound can be potentially used to differentiate demyelinating CTS with sec- ondary axonal degeneration and provide better treatment guidance.

Impact of tumour histological subtype on chemotherapy outcome in advanced oesophageal cancer

World Journal of Gastrointestinal Oncology 2017年第8期9卷 333-340页

作者： Michael Davidson Ian chau David Cunningham Komel Khabra Timothy Iveson Tamas Hickish Matthew Seymour Naureen Starling Royal Marsden Hospital NHS Foundation Trust London and Surrey Southampton University Hospital NHS Trust and Salisbury Hospital NHS Foundation Trust Department of Haematology and Oncology Bournemouth University and Poole Hospital NHS Trust St James’s Institute of Oncology St James’s Hospital

To investigate the impact of histology on outcome in advanced oesophageal cancer treated with first-line fluoropyrimidine-based chemotherapy. METHODSIndividual patient data were pooled from three randomised phase III trials of fluoropyrimidine-based chemotherapy ± platinum/anthracycline in patients with advanced, untreated gastroesophageal adenocarcinoma or squamous cell carcinoma (SCC) randomised between 1994 and 2005. The primary endpoint was overall survival of oesophageal cancer patients according to histology. Secondary endpoints were response rates and a toxicity composite endpoint. RESULTSOf the total 1836 randomised patients, 973 patients (53%) were eligible (707 patients with gastric cancer were excluded), 841 (86%) had adenocarcinoma and 132 (14%) had SCC. There was no significant difference in survival between patients with adenocarcinoma and SCC, with median overall survivals of 9.5 mo vs 7.6 mo (HR = 0.85, 95%CI: 0.70-1.03, P = 0.09) and one-year survivals of 38.8% vs 28.2% respectively. The overall response rate to chemotherapy was 44% for adenocarcinoma vs 33% for SCC (P = 0.01). There was no difference in the frequency of the toxicity composite endpoint between the two groups. CONCLUSIONThere was no significant difference in survival between adenocarcinoma and SCC in patients with advanced oesophageal cancer treated with fluoropyrimidine-based chemotherapy despite a trend for worse survival and less chemo-sensitivity in SCC. Tolerance to treatment was similar in both groups. This analysis highlights the unmet need for SCC-specific studies in advanced oesophageal cancer and will aid in the design of future trials of targeted agents.

Journal of Environmental Science and Engineering(A) 2014年第3期3卷 141-149页

作者： chau Tran Vinh Nguyen Minh Khuyen Nguyen Hong Hieu Doan Van long Nguyen Tien Bach Trinh ThiThu Van Department of Water Resources Management Ministry of Natural Resources and Environment Hanoi 100000 Vietnam

This paper presents the quantitative assessment results of rainwater supply to groundwater in Cai Phan Rang River basin, Ninh Thuan province, Vietnam. In order to obtain the results, the authors developed two experimental areas with 10 wells which were monitored in one year to assess the infiltration supply of rainwater to groundwater. The results of this research assessed the amount of rainwater infiltrates into groundwater varies from 307.16-314.98 tam·year^-1, average is 311 mm·year^-1. The findings are significant in terms of science which identify sources of groundwater storage from the infiltration supply of rainwater. The findings are also practical in suggesting measures to reserve groundwater for the purpose of socio-economic development in the study area.
