| 1 | Drain amylase value as an early predictor of pancreatic fistula after cephalic duodenopancreatectomy显示文摘AIM:To determine predictors of clinically relevant pancreatic fistulas(CRPF)by measuring drain fluid amylase(DFA)in the early postoperative period.METHODS:This prospective clinical study included382 patients with periampullary tumors that were surgically resected at our department between March 2005and October 2012.A cephalic duodenopancreatectomy (DP)was performed on all patients.Two closed suction drains were placed at the end of the surgery.The highest postoperative DFA value was recorded and analyzed during the first three postoperative days and on subsequent days if the drains were kept longer.Pancreatic fistula(PF)was classified according to the International Study Group of Pancreatic Fistula(ISGPF)criteria.Postoperative complications were defined according to the Dindo-Clavien classification.All data were statistically analyzed.The optimal thresholds of DFA levels on the first,second and third postoperative days were estimated by constructing receiver operating curves,generated by calculating the sensitivities and specificities of the DFA levels.The DFA level limits were used to differentiate between the group without PF and the groups with biochemical pancreatic fistula(BPF)and CRPF.RESULTS:Pylorus-preserving duodenopancreatectomy was performed on 289(75.6%)patients,while the remaining patients underwent a classic Whipple procedure(CW).The total incidence of PF was 37.7%(grade A22.8%,grade B 11.0%and grade C 3.9%).Soft pancreatic texture(SPT)was present in 58.3%of patients who developed PF.Mortality was 4.2%.The median DFA value on the first postoperative day(DFA1)in patients who developed PF was 4520 U/L(range 350-99000 U/L)for grade A fistula(BPF)with a SPT and a diameter of the main pancreatic duct(MPD)of≤3 mm.For grade B/C(CRPF),the median DFA1 value was 8501 U/L(range377-92060 U/L)with a SPT and MPD of≤3 mm.These values were significantly higher when compared to the patients who did not have PF(122;range 5-37875 U/L).The upper limit of DFA values for the first 3 postoperative days in the examined stages of PF were:DFA1 1200U/L for the BPF and CRPF;DFA3 350 U/L for BPF and DFA3 800 U/L for CRPF.The determined values were highly significant and demonstrated a reliable diagnostic test for both BPF and CRPF.CONCLUSION:DFA1≥1200 U/L is an important predictive factor for PF of any degree.The trend of DFA3(decrease of<50%)compared to DFA1 is a significant factor in the differentiation of CRPF from transient BPF. | Vladimir D Dugalic Djordje M Knezevic Vladan N Obradovic Miroslava G Gojnic-Dugalic Slavko V Matic Aleksandra R Pavlovic-Markovic Predrag D Dugalic Srbislav M Knezevic | 2014 | World Journal of Gastroenterology2014，20，26： | 7 |

| 3 | Engineering of dendritic dopant-free hole transport molecules:enabling ultrahigh fill factor in perovskite solar cells with optimized dendron construction显示文摘Developing dopant-free hole-transporting materials(HTMs)for high-performance perovskite solar cells(PVSCs)has been a very active research topic in recent years since HTMs play a critical role in optimizing interfacial charge carrier kinetics and in turn determining device performance.Here,a novel dendritic engineering strategy is first utilized to design HTMs with a D-A type molecular framework,and diphenylamine and/or carbazole is selected as the building block for constructing dendrons.All HTMs show good thermal stability and excellent film morphology,and the key optoelectronic properties could be fine-tuned by varying the dendron structure.Among them,MPA-Cz-BTI and MCz-Cz-BTI exhibit an improved interfacial contact with the perovskite active layer,and non-radiative recombination loss and charge transport loss can be effectively suppressed.Consequently,high power conversion efficiencies(PCEs)of 20.8%and 21.35%are achieved for MPA-Cz-BTI and MCz-Cz-BTI based devices,respectively,accompanied by excellent long-term storage stability.More encouragingly,ultrahigh fill factors of 85.2%and 83.5%are recorded for both devices,which are among the highest values reported to date.This work demonstrates the great potential of dendritic materials as a new type of dopant-free HTMs for high-performance PVSCs with excellent FF. | Wei Chen Yang Wang Bin Liu Yajun Gao Ziang Wu Yongqiang Shi Yumin Tang Kun Yang Yujie Zhang Weipeng Sun Xiyuan Feng Frédéric Laquai Han Young Woo Aleksandra B.Djurisic Xugang Guo Zhubing He | 2021 | Science China Chemistry2021，64，1： | 2 |
