| 1 | Roux-en-Y versus BillrothⅠreconstruction after distal gastrectomy for gastric cancer:A meta-analysis显示文摘AIM:To conduct a meta-analysis to compare Rouxen-Y(R-Y) gastrojejunostomy with gastroduodenal Billroth Ⅰ(B-Ⅰ) anastomosis after distal gastrectomy(DG) for gastric cancer.METHODS:A literature search was performed to identify studies comparing R-Y with B-Ⅰ after DG for gastric cancer from January 1990 to November 2012 in Medline,Embase,Science Citation Index Expanded and the Cochrane Central Register of Controlled Trials in The Cochrane Library.Pooled odds ratios(OR) or weighted mean differences(WMD) with 95%CI were calculated using either fixed or random effects model.Operative outcomes such as operation time,intraoperative blood loss and postoperative outcomes such as anastomotic leakage and stricture,bile reflux,remnant gastritis,reflux esophagitis,dumping symptoms,delayed gastric emptying and hospital stay were the main outcomes assessed.Meta-analyses were performed using RevMan 5.0 software(Cochrane library).RESULTS:Four randomized controlled trials(RCTs) and 9 non-randomized observational clinical studies(OCS) involving 478 and 1402 patients respectively were included.Meta-analysis of RCTs revealed that R-Y reconstruction was associated with a reduced bile reflux(OR 0.04,95%CI:0.01,0.14;P < 0.00 001) and remnant gastritis(OR 0.43,95%CI:0.28,0.66;P = 0.0001),however needing a longer operation time(WMD 40.02,95%CI:13.93,66.11;P = 0.003).Metaanalysis of OCS also revealed R-Y reconstruction had a lower incidence of bile reflux(OR 0.21,95%CI:0.08,0.54;P = 0.001),remnant gastritis(OR 0.18,95%CI:0.11,0.29;P < 0.00 001) and reflux esophagitis(OR 0.48,95%CI:0.26,0.89;P = 0.02).However,this reconstruction method was found to be associated with a longer operation time(WMD 31.30,95%CI:12.99,49.60;P = 0.0008).CONCLUSION:This systematic review point towards some clinical advantages that are rendered by R-Y compared to B-Ⅰ reconstruction post DG.However there is a need for further adequately powered,welldesigned RCTs comparing the same. | Jun-Jie Xiong Kiran Altaf Muhammad A Javed Quentin M Nunes Wei Huang Gang Mai Chun-Lu Tan Rajarshi Mukherjee Robert Sutton Wei-Ming Hu Xu-Bao Liu | 2013 | World Journal of Gastroenterology2013，19，7： | 33 |
| 2 | 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 |
| 3 | Changes in Nutrient-Homeostasis and Reserves Metabolism During Rice Seed Priming:Consequences for Seedling Emergence and Growth显示文摘In this study influence of different seed priming treatments on the nutrient-homeostasis and reserve metabolism during seedling emergence and growth of rice were determined. Seed priming treatments included pre-germination, hydropriming for 48 h, osmohardening with KCl and CaCl2, ascorbate priming and hardening. All treatments shortened the emergence time and enhanced the energy and index of seedling emergence. Seedlings from primed seeds had greater length, number of roots and fresh and dry mass than control. Among the treatments, CaCl2, ascorbate and KCl proved better in enhancing emergence and seedling growth. Seed priming changed the pattern of N and Ca2+ homeostasis both of the seeds and seedlings, which were associated to enhancing α-amylase activity and reducing sugars content. Positive correlations of seedling attributes with nutrient content suggested that as a result of seed priming, most of N and Ca2+ were partitioned to embryo, which enhanced seedling emergence and subsequent growth of rice seedlings. | Muhammad Farooq Shahzad M A Basra Abdul Wahid Nazir Ahmad | 2010 | Agricultural Sciences in China2010，9，2： | 4 |
| 4 | Surface plasmon polariton at the interface of dielectric and graphene medium using Kerr effect显示文摘We theoretically investigate the control of surface plasmon polariton(SPP) generated at the interface of dielectric and graphene medium under Kerr nonlinearity. The controlled Kerr nonlinear signal of probe light beam in a dielectric medium is used to generate SPPs at the interface of dielectric and graphene medium. The positive, negative absorption, and dispersion properties of SPPs are modified and controlled by the control and Kerr fields. A large amplification(negative absorption) is noted for SPPs under the Kerr nonlinearity. The normal/anomalous slope of dispersion and propagation length of SPPs is modified and controlled with Kerr nonlinearity. This leads to significant variation in slow and fast SPP propagation. The controlled slow and fast SPP propagation may predict significant applications in nano-photonics, optical tweezers, photovoltaic devices, plasmonster, and sensing technology. | Bakhtawar Muhammad Haneef B A Bacha H Khan M Atif | 2018 | Chinese Physics B2018，27，11： | 3 |
| 5 | Seed priming improves early seedling vigor, growth and productivity of spring maize显示文摘Potential of seed priming treatments in improving the performance of early planted maize was evaluated against timely planting. Seeds of maize hybrid FH-810 were soaked in water(hydropriming), Ca Cl2(2.2%, osmopriming), moringa leaf extracts(MLE 3.3%, osmopriming) and salicylic acid(SA, 50 mg L–1, hormonal priming) each for 18 h. Untreated and hydroprimed seeds were taken as control. Seeds primed with SA took less time in emergence and had high vigor in early planted maize. Amongst treatments, hormonal priming, reduced the electrical conductivity, increased the leaf relative and chlorophyll contents followed by osmopriming with Ca Cl2 at seedling stage. Likewise, plant height, grain rows and 1 000-grain weight, grain and biological yield and harvest index were also improved by seed priming; however hormonal priming and osmopriming with MLE were more effective in this regard. Improved yield performance by hormonal priming or osmopriming with MLE in early planting primarily owed to increased leaf area index, crop growth and net assimilation rates, and maintenance of green leaf area at maturity. In conclusion, osmopriming with MLE and hormonal priming with SA were the most economical treatments in improving productivity of early planted spring maize through stimulation of early seedling growth at low temperature. | Hafeez ur Rehman Hassan Iqbal Shahzad M A Basra Irfan Afzal Muhammad Farooq Abdul Wakeel WANG Ning | 2015 | Journal of Integrative Agriculture2015，14，9： | 3 |

| 9 | Structural, electronic, and optical properties of ZnO_(1-x)Se_x alloys using first-principles calculations显示文摘The structural, electronic, and optical properties of binary ZnO, ZnSe compounds, and their ternary ZnO 1-x Se x alloys are computed using the accurate full potential linearized augmented plane wave plus local orbital (FP-LAPW + lo) method in the rocksalt (B1) and zincblende (B3) crystallographic phases. The electronic band structures, fundamental energy band gaps, and densities of states for ZnO 1-x Se x are evaluated in the range 0 ≤ x ≤ 1 using Wu-Cohen (WC) generalized gradient approximation (GGA) for the exchange-correlation potential. Our calculated results of lattice parameters and bulk modulus reveal a nonlinear variation for pseudo-binary and their ternary alloys in both phases and show a considerable deviation from Vegard's law. It is observed that the predicted lattice parameter and bulk modulus are in good agreement with the available experimental and theoretical data. We establish that the composition dependence of band gap is semi-metallic in B1 phase, while a direct band gap is observed in B3 phase. The calculated density of states is described by taking into account the contribution of Zn 3d, O2p, and Se 4s, and the optical properties are studied in terms of dielectric functions, refractive index, reflectivity, and energy loss function for the B3 phase and are compared with the available experimental data. | Muhammad Rashid Fayyaz Hussain Muhammad Imran S A Ahmad N A Noor M U Sohaib S M Alay-e-Abbas | 2013 | Chinese Physics B2013，22，8： | 2 |
