Plants, the primary producers on the Earth, use solar energy to convert CO2 and H2O into various organic compounds. Over the past 10 000 years, humans have exploited the plant synthesizing capability and developed agricultural practice to meet the basic needs for food, fiber, energy, chemicals, and medicines. Actually, all of the products are an assortment of compounds synthesized in plants though a variety of metabolic processes. It has been estimated that any given plant species can synthesize 5000-25 000 different compounds （Trethewey, 2004）. More than 100 000 metabolites, which may account for approximately 10% of the total natural products, have been identified in the plant kingdom.

BACKGROUND: Recent international multidisciplinary consultation proposed the use of local (sterile or infected pancreatic necrosis) and/or systemic determinants (organ failure) in the stratification of acute pancreatitis. The present study was to validate the moderate severity category by international multidisciplinary consultation definitions. METHODS: Ninety-two consecutive patients with severe acute pancreatitis (according to the 1992 Atlanta classification) were classified into (i) moderate acute pancreatitis group with the presence of sterile (peri-) pancreatic necrosis and/or transient organ failure; and (ii) severe/critical acute pancreatitis group with the presence of sterile or infected pancreatic necrosis and/ or persistent organ failure. Demographic and clinical outcomes were compared between the two groups. RESULTS: Compared with the severe/critical group (n=59), the moderate group (n=33) had lower clinical and computerized tomographic scores (both P<0.05). They also had a lower incidence of pancreatic necrosis (45.5% vs 71.2%, P=0.015), infection (9.1% vs 37.3%, P=0.004), ICU admission (0% vs 27.1%, P=0.001), and shorter hospital stay (15 +/- 5 vs 27 +/- 12 days; P<0.001). A subgroup analysis showed that the moderate group also had significantly lower ICU admission rates, shorter hospital stay and lower rate of infection compared with the severe group (n=51). No patients died in the moderate group but 7 patients died in the severe/critical group (4 for severe group). CONCLUSIONS: Our data suggest that the definition of moderate acute pancreatitis, as suggested by the international multidisciplinary consultation as sterile (pen-) pancreatic necrosis and/or transient organ failure, is an accurate category of acute pancreatitis.

OBJECTIVE To investigate the association between current and former smoking and the risk of mortality in elderly Chinese *** Our study participants were elderly(≥60 years)men recruited in a suburban town of *** smoking status was categorized as never smoking,remote(cessation>5 years)and recent former smoking(cessation≤5 years),and light-to-moderate(≤20 cigarettes/day)and heavy current smoking(>20 cigarettes/day).Cox proportional hazards models and restricted cubic splines were used to examine the associations of *** The 1568 participants had a mean age of 68.6±7.1 *** all participants,311 were never smokers,201 were remote former smokers,133 were recent former smokers,783 were light-to-moderate current smokers and 140 were heavy current *** a median follow-up of 7.9 years,all-cause,cardiovascular and non-cardiovascular deaths occurred in 267,106 and 161 participants,*** current smokers had the highest risk of all-cause and non-cardiovascular mortality,with an adjusted hazard ratio(HR)of 2.30(95%CI:1.34-4.07)and 3.98(95%CI:2.03-7.83)versus never smokers,*** former smokers also had a higher risk of all-cause(HR=1.62,95%CI:1.04-2.52)and non-cardiovascular mortality(HR=2.40,95%CI:1.32-4.37)than never *** regression restricted cubic spline models showed the highest risk of all-cause and non-cardiovascular mortality within 5 years of smoking cessation and decline *** subgroup analyses showed interaction between smoking status and pulse rate(≥70 beats/min vs.<70 beats/min)in relation to the risk of all-cause and non-cardiovascular mortality,with a higher risk in current versus never smokers in those participants with a pulse rate below 70 beats/*** Cigarette smoking in elderly Chinese confers significant risks of mortality,especially when recent former smoking is considered together with current smoking.

Developing high-performance separation membrane with good durability is a highly desired while challenging ***,we reported the successful fabrication of chemically and mechanically durable superhydrophobic membrane that was prepared by embedding UiO-66 as size-sieving sites within the supramolecular fiber structure of collagen fiber membrane(CFM),followed by the polydimethylsiloxane(PDMS)*** as-prepared CFM/UiO-66(12)/PDMS membrane featured capillary effect-enhanced separation flux and homogeneous porous channels guaranteed high separation *** utilized as double-layer separation membranes,this new type of composite membranes separated various surfactant stabilized water-in-oil microemulsions and nanoemulsions,with the separation efficiency high up to 99.993%and the flux as high as 973.3 L m−2 h−*** with commercial polytetrafluoro ethylene(PTFE)membrane,the advantage of the double-layer CFM/UiO-66(12)/PDMS membranes in separation flux was evident,which exhibited one order of magnitude higher than that of commercial PTFE *** CFM/UiO-66(12)/PDMS membrane was acid-alkali tolerant,UV-aging resistant and reusable for emulsion ***,the CFM/UiO-66(12)/PDMS membrane was mechanically durable against strong mechanical abrasion,which was still capable of separating diverse water-in-oil emulsions after the abrasion with sandpaper and assembled as double-layer separation *** anticipate that the combination of CFM and metal organic frameworks(MOFs)is an effective strategy for fabricating high-performance separation membrane with high mechanical and chemical durability.

单层网壳是近年来大型场馆的常用结构形式,具有结构轻薄、造型多变的特点。由于单层网壳平面外刚度小,因此其整体稳定性是结构设计需要考虑的关键问题。以实际工程案例为背景,研究了异形单层网壳结构的结构受力机制,对不同结构方案的挠度控制效果和经济指标进行了优化比选。采用ANSYS软件对优化完成后的网壳体系进行模态分析,考虑初始几何缺陷的双重非线性整体稳定分析,并分析了整体稳定性对几何缺陷的敏感度。一系列分析证明:通过加强体系的鲁棒性,可在降低用钢量的情况下,使结构稳定承载力仍满足设计要求。

In order to assure a real-time medical care for the elders who live alone or have a chronic disease and also to improve the responsiveness and quality of the community hospital, a community health service architecture was designed according to the Internet of Things on Health-Care. The users' body physiological and sports information can be collected intelligently by the health sensors at home and then the health information can be transmitted to the community health-care center through networks after information processing. The community doctors can provide a medical service on kinds of video, voice or email according to the users' process notes, test data and symptoms. Of course, doctors also can communicate and share their opinions with other specialist who is online. The key technology of this system is Internet of Things on Health-Care, which system can get users' health information actively and then make out intelligent decisions promptly and finally provide a more personal health service.

Since 1982,Landsat series of satellite sensors continuously acquired thermal infrared images of the Earth’s land *** this study,Landsat 5,7,and 8 land surface temperature(LST)products in the conterminous United States from 2009 to 2019 were validated using in situ measurements collected at 6 SURFRAD(Surface Radiation Budget Network)sites,6 ARM(Atmospheric Radiation Measurement)sites,and 9 NDBC(National Data Buoy Center)*** results indicate that a relatively consistent performance among Landsat 5,7,and 8 LST products is obtained for most sites due to the consistent LST retrieval algorithm in conjunction with the same atmospheric compensation and land surface emissivity(LSE)correction methods for Landsat 5,7,and 8 *** bias and root mean square error(RMSE)of Landsat LST product are obtained at some vegetated sites due to incorrect LSE estimation where LSE is invariant with the increasing of normalized difference vegetation index(NDVI).Except for the sites with incorrect LSE estimation,a mean bias(RMSE)of the differences between Landsat LST and in situ LST is 1.0 K(2.1 K)over snow-free land surfaces,−1.1 K(1.6 K)over snow surfaces,and−0.3 K(1.1 K)over water surfaces.
