| 1 | 青海共和盆地达连海湖泊流域表土花粉-气候响应面分析显示文摘孢粉分析是研究过去全球变化的一种重要方法,而研究花粉与现代气候之间的相互关系是古气候定量重建研究中的前沿课题。要预测未来气候的中长期变化,必须从花粉记录中定量提取古气候信息,建立的多种孢粉-气候数学模型必须经过不同边界条件下的古气候数据检验校正才能应用到实际当中。花粉-气候响应面方法是考虑了花粉与气候间的非线形关系上,提出的将现代花粉丰度在地理空间的分布转换为气候空间的分布,并以提供定量的古气候数据,已被广泛应用于COHMAP等各种重要古气候研究项目。本文就是利用该方法,以青藏高原东北部共和盆地达连海湖泊流域54个表土样品中的花粉丰度及采样点的气候参数为基础数据,通过主成分分析选择了特征值高且指示意义明显的4种花粉类型,对其丰度与7月平均温度及年平均降水量两个气候参数进行多项式回归分析,其结果显示模型对数据拟合较好,为定量重建该区古气候变化提出了较为准确的数量指标。 | 陈英玉 QING Hai-ruo VELEZ M I LIU Meng 魏豆豆 蔡遥 | 2014 | 地球学报2014，35，1： | 10 |
| 2 | Meta-analysis of subtotal stomach-preserving pancreaticoduodenectomy vs pylorus preserving pancreaticoduodenectomy显示文摘AIM: To investigate the differences in outcome following pylorus preserving pancreaticoduodenectomy(PPPD) and subtotal stomach-preserving pancreaticoduodenectomy(SSPPD).METHODS: Major databases including Pub Med(Medline), EMBASE and Science Citation Index Expanded and the Cochrane Central Register of Controlled Trials(CENTRAL) in The Cochrane Library were searched for comparative studies between patients with PPPD and SSPPD published between January 1978 and July 2014. Studies were selected based on specific inclusion and exclusion criteria. The primary outcome was delayed gastric emptying(DGE). Secondary outcomes included operation time, intraoperative blood loss, pancreatic fistula, postoperative hemorrhage, intraabdominal abscess, wound infection, time to starting liquid diet, time to starting solid diet, period of nasogastric intubation, reinsertion of nasogastric tube, mortality and hospital stay. The pooled odds ratios(OR) or weighted mean difference(WMD) with 95% confidence intervals(95%CI) were calculated using either a fixed-effects or random-effects model. RESULTS: Eight comparative studies recruiting 650 patients were analyzed, which include two RCTs, one non-randomized prospective and 5 retrospective trial designs. Patients undergoing SSPPD experienced significantly lower rates of DGE(OR = 2.75; 95%CI: 1.75-4.30, P < 0.00001) and a shorter period of nasogastric intubation(OR = 2.68; 95%CI: 0.77-4.58,P < 0.00001), with a tendency towards shorter time to liquid(WMD = 2.97, 95%CI:-0.46-7.83; P = 0.09) and solid diets(WMD = 3.69, 95%CI:-0.46-7.83; P = 0.08) as well as shorter inpatient stay(WMD = 3.92, 95%CI:-0.37-8.22; P = 0.07), although these latter three did not reach statistical significance. PPPD, however, was associated with less intraoperative blood loss than SSPPD [WMD =-217.70, 95%CI:-429.77-(-5.63); P = 0.04]. There were no differences in other parameters between the two approaches, including operative time(WMD =-5.30, 95%CI:-43.44-32.84; P = 0.79), pancreatic fistula(OR = 0.91; 95%CI: 0.56-1.49; P = 0.70), postoperative hemorrhage(OR = 0.51; 95%CI: 0.15-1.74; P = 0.29), intraabdominal abscess(OR = 1.05; 95%CI: 0.54-2.05; P = 0.89), wound infection(OR = 0.88; 95%CI: 0.39-1.97; P = 0.75), reinsertion of nasogastric tube(OR = 1.90; 95%CI: 0.91-3.97; P = 0.09) and mortality(OR = 0.31; 95%CI: 0.05-2.01; P = 0.22).CONCLUSION: SSPPD may improve intraoperative and short-term postoperative outcomes compared to PPPD, especially DGE. However, these findings need to be further ascertained by well-designed randomized controlled trials. | Wei Huang Jun-Jie Xiong Mei-Hua Wan Peter Szatmary Shameena Bharucha Ilias Gomatos Quentin M Nunes Qing Xia Robert Sutton Xu-Bao Liu | 2015 | World Journal of Gastroenterology2015，21，20： | 8 |
| 3 | Prediction of the severity of acute pancreatitis on admission by urinary trypsinogen activation peptide: A meta-analysis显示文摘AIM: To undertake a meta-analysis on the value of urinary trypsinogen activation peptide (uTAP) in predicting severity of acute pancreatitis on admission. METHODS: Major databases including Medline, Embase, Science Citation Index Expanded and the Cochrane Central Register of Controlled Trials in the Cochrane Library were searched to identify all relevant studies from January 1990 to January 2013. Pooled sensitivity, specificity and the diagnostic odds ratios (DORs) with 95%CI were calculated for each study and were compared to other systems/biomarkers if mentioned within the same study. Summary receiver-operating curves were conducted and the area under the curve (AUC) was evaluated. RESULTS: In total, six studies of uTAP with a cut-off value of 35 nmol/L were included in this meta-analysis. Overall, the pooled sensitivity and specificity of uTAP for predicting severity of acute pancreatitis, at time of admission, was 71% and 75%, respectively (AUC = 0.83, DOR = 8.67, 95%CI: 3.70-20.33). When uTAP was compared with plasma C-reactive protein, the pooled sensitivity, specificity, AUC and DOR were 0.64 vs 0.67, 0.77 vs 0.75, 0.82 vs 0.79 and 6.27 vs 6.32, respectively. Similarly, the pooled sensitivity, specificity, AUC and DOR of uTAPvs Acute Physiology and Chronic Health Evaluation Ⅱ within the first 48 h of admission were found to be 0.64 vs 0.69, 0.77 vs 0.61, 0.82 vs 0.73 and 6.27vs 4.61, respectively. CONCLUSION: uTAP has the potential to act as a stratification marker on admission for differentiating disease severity of acute pancreatitis. | Wei Huang Kiran Altaf Tao Jin Jun-Jie Xiong Li Wen Muhammad A Javed Marianne Johnstone Ping Xue Christopher M Halloran Qing Xia | 2013 | World Journal of Gastroenterology2013，19，28： | 7 |
