Objective:China is a developing country with urban–rural disparities and accelerating population aging.Therefore,quantifying the effects of population aging on the cancer mortality burden is urgently needed.Methods:Using data from China’s death surveillance datasets(2004–2017),we decomposed and quantified the effects of population aging and factor variations on cancer mortality rates in urban and rural China during 2004–2017 through a decomposition method.R ratios were used to assess the extent of the mortality decreases attributable to factor variations offsetting the increases attributable to population aging for 4 aging-related cancers(lung,colorectal,esophageal,and stomach cancer).Results:Overall,population aging has led to continued increases in cancer mortality rates in China during 2004–2017(mortality rates attributable to population aging:8.63/100,000 for urban men,4.21/100,000 for urban women,11.95/100,000 for rural men,and 5.66/100,000 for rural women).The 4 cancers displayed 3 patterns.The mortality rates from lung cancer in rural China and from colorectal cancer nationwide increased because of both population aging and factor variations.Population aging was primarily responsible for the growing mortality due to lung cancer in urban areas.However,for esophageal and stomach cancer,the effect of population aging was not dominant,thus resulting in decreases in mortality rates.Conclusions:Health resource allocation should prioritize areas or cancers more adversely affected by population aging.The burden of cancer will continue to increase in the future,because of rapid population aging,but can still be offset or even reversed with enhanced cancer control and prevention.

Prussian blue analogues(PBAs) are considered as superior cathode materials for potassium-ion batteries(PIBs) because of their three-dimensional open framework structure,high stability,and low cost.However,the intrinsic lattice defects and low potassium content typically results in poor rate and cycling performance,thus limited their practical applications.In this work,high-quality K1.64FeFe(CN)6(PW-HQ)material with less crystalline water(6.21%) and high potassium content(1.64 mol^(-1)) was successfully synthesized by a novel coprecipitation method with potassium citrate(K-CA) and potassium chloride(KCl) addition.Specifically,the electrode delivers a reversible capacity of 113.1 mA h g^(-1)at the current rate of 50 mA g^(-1)with~100% coulombic efficiency.Besides,the electrode retained 90% reversible capacity at 500 mA g^(-1)current density after 1000 cycles,indicating only 0.01% capacity decay per cycle.Moreover,we have revealed that the introduction of K-CA controlled the chelating rate of Fe(Ⅱ) and the addition of KCl increased the K+content,hence improving the capacity and stability of the asprepared electrodes.Structural evolution and potassium storage mechanism were further investigated by detailed ex-situ X-ray diffraction and in-situ Raman measurements,which demonstrated reversible potassiation/depotassiation behavior and negligible volume change during the electrochemical process.In general,this work provides an efficient strategy to eliminate water contents in Prussian blue cathode and improve its electrochemical performance,which plays a key role in promoting the industrialization of potassium ion batteries.

Bronze phase titanium dioxide(TiO_(2)(B))could be a promising high-power anode for lithium ion battery.However,TiO_(2)(B)is a metastable material,so the as-synthesized samples are inevitably accompanied by the existence of anatase phases.It has been found that the TiO_(2)(B)'s purity is positively correlated with its electrochemical performance.Herein,we have established an accurate quantification of the TiO_(2)(B)/anatase ratio,by figuring out the function between the purity of TiO_(2)(B)phase in the high purity range and its Raman spectra features in combination of the calibration by the synchrotron radiation X-ray diffraction(XRD).Compared with the time-consuming electrochemical method,the rapid,sensitive and non-destructive features of Raman spectroscopy have made it a promising candidate for determining the purity of TiO_(2)(B).Further,the correlations developed in this work should be instructive in synthesizing pure TiO_(2)(B)and furthermore optimizing its electrochemical charge storage properties.

Stabilizing SEI by cyclic ethers toward enhanced K^(+) storage in graphite

The poor cycling stability of graphite in traditional ester electrolyte limits its applications as anodes for potassium ion batteries(KIBs).Herein,we demonstrate that the introduction of cyclic ether co-solvents into ester electrolytes can remarkably enhance the cycling stability of graphite anodes.The graphite anode in ester electrolyte with cyclic ether could achieve a reversible capacity of 196.1 m Ah g^(-1) after 100 cycles at 0.3 C(1 C=280 m A g^(-1)),about three times higher than those in ester electrolytes with or without linear ether.Compared with the SEI formed in ester electrolytes,the addition of tetrahydrofuran promotes the generation of K_(2)CO_(3) and ethylene oxide oligomers(PEO),of which the K_(2)CO_(3) is expected to be more conductive and PEO is mechanically robust.The more uniform,conductive and stable solid electrolyte interphases(SEIs)on graphite in electrolytes with cyclic ethers contribute to the enhancement of the electrochemical performances of graphite.This work provides a novel design of commercialized electrolytes to achieve high-performance anodes for KIBs,which potentially accelerates the development of KIBs.

The design of supercapacitor materials with both high areal capacity(C)and high mass loading is vitally important for enhancing energy density(E).Herein,we prepared a NiCosingle bondOH/NiCoOOH composite film consisting of NiCosingle bondOH/NiCoOOH nanosheets on an expanded graphite paper(EGP)by using a facial anodization method.The as-prepared NiCosingle bondOH/NiCoOOH film exhibits ultra-high C of 11 mA·h·cm^(-2)at a mass loading of 165 mg·cm^(-2),high rate capability of 71%and excellent cycling stability of 95%after 12000 cycles.The outstanding performance is ascribed to the low-crystalline feature of the NiCosingle bondOH/NiCoOOH nanosheets,and the synergistic effect of the NiCosingle bondOH and NiCoOOH phases and high conductive porous EGP.An aqueous asymmetric supercapacitor,assembled with the NiCosingle bondOH/NiCoOOH on EGP and Fe_(2)O_(3)on EGP as positive-and negative-electrode,respectively,shows a highest E of 3.8 mW·h·cm^(-2)at a power density(P)of 4 mW·cm^(-2)and a maximum P of 107 mW·cm^(-2)at an E of 2.7 mW·h·cm^(-2).

Complicated relationships exist in both occurrence and progression of surgical complications,which are difficult to account for using a separate quantitative method such as prediction or grading.Data of 51,030 surgical inpatients were collected from four academic/teaching hospitals in a prospective cohort study in China.The relationship between preoperative factors,22 common complications,and death was analyzed.With input from 54 senior clinicians and following a Bayesian network approach,a complication grading,cluster-visualization,and prediction(GCP)system was designed to model pathways between grades of complication and preoperative risk factor clusters.In the GCP system,there were 11 nodes representing six grades of complication and five preoperative risk factor clusters,and 32 arcs representing a direct association.Several critical targets were pinpointed on the pathway.Malnourished status was a fundamental cause widely associated(7/32 arcs)with other risk factor clusters and complications.American Society of Anesthesiologists(ASA)score≥3 was directly dependent on all other risk factor clusters and influenced all severe complications.Grade III complications(mainly pneumonia)were directly dependent on4/5 risk factor clusters and affected all other grades of complication.Irrespective of grade,complication occurrence was more likely to increase the risk of other grades of complication than risk factor clusters.
