3Modeling on Heat and Mass Transfer in Stored Wheat during Forced Cooling Ventilation显示文摘A mathematical model based on the theory of heat and mass transfer in porous media was developed to simulate the evolution of grain temperature and moisture content in a wheat storage bin during ventilation with cooling air at the constant temperature and humidity.Unlike the previous works on this aspect,the present work was not focused on cooling the stored grain by ventilation with ambient air,but with the refrigerated air.Validation was performed by comparing between predicted and measured grain temperature and grain moisture content for two cases.Predicted data were in reasonable good agreement with measured ones.The model and the parameter values used in the model are applicable for predicting temperature and moisture of stored grains under ventilation conditions.Yuancheng WANG,Haifeng DUAN,Hao ZHANG and Zhaohong FANG College of Thermal Energy Engineering,Shandong Jianzhu University,Jinan 250101,China 2010Journal of Thermal Science2010,19,2:27
4Hemodynamic analysis of esophageal varices in patients with liver cirrhosis using color Doppler ultrasound显示文摘AIM: To study the portal hemodynamics and their relationship with the size of esophageal varices seen at endoscopy and to evaluate whether these Doppler ultrasound parameters might predict variceal bleeding in patients with liver cirrhosis and portal hypertension.METHODS: One hundred and twenty cirrhotic patients with esophageal varices but without any previous bleeding were enrolled in the prospective study. During a 2-year observation period, 52 patients who had at least one episode of acute esophageal variceal hemorrhage constituted the bleeding group, and the remaining 68 patients without any previous hemorrhage constituted the non-bleeding group. All patients underwent endoscopy before or after color Doppler-ultrasonic examination, and images were interpreted independently by two endoscopists. The control group consisted of 30 healthy subjects, matched to the patient group in age and gender. Measurements of diameter,flow direction and flow velocity in the left gastric vein (LGV) and the portal vein (PV) were done in all patients and controls using color Doppler unit. After baseline measurements, 30 min after oral administration of 75 g glucose in 225 mL, changes of the diameter, flow velocity and direction in the PV and LGV were examined in 60 patients with esophageal varices and 15 healthy controls.RESULTS: The PV and LGV were detected successfully in 115 (96%) and 105 (88%) of 120 cirrhotic patients,respectively, and in 27 (90%) and 21 (70%) of 30 healthy controls, respectively. Among the 120 cirrhotic patients,37 had F1, 59 had F2, and 24 had F3 grade varices. Compared with the healthy controls, cirrhotic group had a significantly lower velocity in the PV, a significantly greater diameter of the PV and LGV, and a higher velocity in the LGV. In the cirrhotic group, no difference in portal flow velocity and diameter were observed between patients with or without esophageal variceal bleeding (EVB). However, the diameter and blood flow velocity of the LGV were significantly higher for EVB (+) group compared with EVB (-) group (P<0.01).Diameter of the LGV increased with enlarged size of varices.There were differences between F1 and F2, F1 and F3 varices, but no differences between F2 and F3 varices (P = 0.125). However, variceal bleeding was more frequent in patients with a diameter of LGV >6 mm. The flow velocity in the LGV of healthy controls was 8.70±1.91 cm/s (n = 21). In patients with liver cirrhosis, it was 10.3±2.1 cm/s (n = 12) when the flow was hepatopetal and 13.5±2.3 cm/s (n = 87) when it was hepatofugal. As the size of varices enlarged, hepatofugal flow velocity increased (P<0.01) and was significantly different between patients with F1 and F2 varices and between patients with F2 and F3 varices. Variceal bleeding was more frequent in patients with a hepatofugal flow velocity >15 cm/s (32 of 52 patients, 61.5%). Within the bleeding group, the mean LGV blood flow velocity was 16.6±2.62 cm/s. No correlation was observed between the portal blood flow velocity and EVB. In all healthy controls, the flow direction in the LGV was hepatopetal, toward the PV. In patients with F1 varices, flow direction was hepatopetal in 10 patients, to-and-fro state in 3 patients, and hepatofugal in the remaining 18. The flow was hepatofugal in 91% patients with F2 and all F3 varices. Changes in diameter of the PV and LGV were not significant before and after ingestion of glucose (PV: 1.41±1.5 cm before and 1.46±1.6 cm after; LGV: 0.57±1.7 cm before and 0.60±1.5 cm after).Flow direction in the LGV was hepatopetal and to-and-fro in 16 patients and hepatofugal in 44 patients before ingestion of glucose. Flow direction changed to hepatofugal in 9 of 16 patients with hepatopetal and to-and-fro blood flow after ingestion of glucose. In 44 patients with hepatofugal blood flow in the LGV, a significant increase in hepatofugal flow velocity was observed in 38 of 44 patients (86%) with esophageal vadces. There was a relationship between the percentage changes in flow velocity and the size of varices. Patients who responded excessively to food ingestion might have a high risk for bleeding. The changes of blood flow velocity in the LGV were greater than those in the PV (LGV: 28.3±26.1%, PV: 7.2±13.2%, P<0.01), whereas no significant changes in the LGV occurred before and after ingestion of glucose in the control subjects.CONCLUSION: Hemodynamics of the PV is unrelated to the degree of endoscopic abnormalities in patients with liver cirrhosis. The most important combinations are endoscopic findings followed by the LGV hemodynamics.Duplex-Doppler ultrasonography has no value in the identification of patients with cirrhosis at risk of variceal bleeding. Hemodynamics of the LGV appears to be superior to those of the PV in predicting bleeding.Feng-Hua Li Jing Hao Jian-Guo Xia Hong-Li Li Hua Fang 2005World Journal of Gastroenterology2005,11,29:23
5The Chinese Society of Clinical Oncology(CSCO)clinical guidelines for the diagnosis and treatment of nasopharyngeal carcinoma显示文摘Nasopharyngeal carcinoma(NPC)is a malignant epithelial tumor originating in the nasopharynx and has a high incidence in Southeast Asia and North Africa.To develop these comprehensive guidelines for the diagnosis and management of NPC,the Chinese Society of Clinical Oncology(CSCO)arranged a multi-disciplinary team comprising of experts from all sub-specialties of NPC to write,discuss,and revise the guidelines.Based on the findings of evidencebased medicine in China and abroad,domestic experts have iteratively developed these guidelines to provide proper management of NPC.Overall,the guidelines describe the screening,clinical and pathological diagnosis,staging and risk assessment,therapies,and follow-up of NPC,which aim to improve the management of NPC.Ling-Long Tang Yu-Pei Chen Chuan-Ben Chen Ming-Yuan Chen Nian-Yong Chen Xiao-Zhong Chen Xiao-Jing Du Wen-Feng Fang Mei Feng Jin Gao Fei Han Xia He Chao-Su Hu De-sheng Hu Guang-Yuan Hu Hao Jiang Wei Jiang Feng Jin Jin-Yi Lang Jin-Gao Li Shao-Jun Lin Xu Liu Qiu-Fang Liu Lin Ma Hai-Qiang Mai Ji-Yong Qin Liang-Fang Shen Ying Sun Pei-Guo Wang Ren-Sheng Wang Ruo-Zheng Wang Xiao-Shen Wang Ying Wang Hui Wu Yun-Fei Xia Shao-Wen Xiao Kun-Yu Yang Jun-Lin Yi Xiao-Dong Zhu Jun Ma 2021Cancer Communications2021,41,11:22
6Left posterior fascicular block: a new endpoint of ablation for verapamil-sensitive idiopathic ventricular tachycardia显示文摘Background Verapamil-sensitive, idiopathic left ventricular tachycardia (ILVT) with right bundle branch block configuration and left-axis deviation is known to be due to re-entry mechanism but the exact nature of reentrant circuit in ILVT is not fully elucidated. Radiofrequency (RF) ablation was applied during ventricular tachycardia (VT) and termination of the VT or abolishing the inducibility of the tachycardia was used as an endpoint for successful RF. In this study, the left posterior fascicular block in surface electrocardiogram (ECG) was used as a new endpoint of ablation to cure ILVT. Methods Electrophysiological studies and radiofrequency ablation were performed in 39 consecutive patients [30 men, 9 women; age ranging from 10 to 64 years, mean (29±16) years] with verapamil-sensitive ILVT and structurally normal hearts. VT could be terminated by the intravenous administration of verapamil in all patients. The target site was the midseptum of LV where the earliest Purkinje potentials were recorded during VT. RF current was applied to the target site with or without late diastolic potential (LDP) during sinus rhythm in 37 patients and during VT in 2 patients to meet the ablation endpoint: the left posterior fascicular block in the surface ECG. Results Thirty-seven patients with ILVT had been treated by RF ablation during sinus rhythm and two had been treated during VT. All of them met the endpoint of the left posterior fascicular block. Thirty-eight cases were symptom-free without medications during the follow-up period (range from 3 to 95 months, median 17 months). One patient developed a clinical recurrence and the left posterior fascicular block in surface ECG disappeared. The patient received another treatment. The endpoint was met and the procedure was successful. Conclusions The left posterior fascicular block in surface ECG used as an endpoint of RF ablation to treat ILVT is effective. It is important especially in those patients whose VT can not be induced or the inducible condition is unstable. The effective endpoint implied that the left posterior fascicle might be a critical part of the re-entrant circuit.MA Fu-sheng MA Jian TANG Kai HAN Hao JIAYu-he FANG Pi-hua CHU Jian-min PU Jie-lin ZHANG Shu 2006Chinese Medical Journal2006,,5:21

12Calcium channel blockers reduce severe fever with thrombocytopenia syndrome virus (SFTSV) related fatality显示文摘Severe fever with thrombocytopenia syndrome (SFTS),an emerging tick-borne infectious disease caused by a novel phlebovirus (SFTS virus, SFTSV), was listed among the top 10 priority infectious diseases by the World Health Organization due to its high fatality of 12%-50% and possibility of pandemic transmission. Currently, effective anti-SFTSV intervention remains unavailable. Here, by screening a library of FDA-approved drugs, we found that benidipine hydrochloride, a calcium channel blocker (CCB), inhibited SFTSV replication in vitro. Benidipine hydrochloride was revealed to inhibit virus infection through impairing virus internalization and genome replication. Further experiments showed that a broad panel of CCBs, including nifedipine, inhibited SFTSV infection. The anti-SFTSV effect of these two CCBs was further an a lyzed in a humanized mouse model in which CCB treatment resulted in reduced viral load and decreased fatality rate. Importantly, by performing a retrospective clinical investigation on a large cohort of 2087 SFTS patients, we revealed that nifedipine administration enhaneed virus clearance, improved clinical recovery, and remarkably reduced the case fatality rate by >5-fold. These findings are highly valuable for developing potential host-oriented therapeutics for SFTS and other lethal acute viral infections known to be inhibited by CCBs in vitro.Hao Li Lei-Ke Zhang Shu-Fen Li Shao-Fei Zhang Wei-Wei Wan Yu-Lan Zhang Qi-Lin Xin Ke Dai Yuan-Yuan Hu Zhi-Bo Wang Xiang-Tao Zhu Yu-Jie Fang Ning Cui Pan-He Zhang Chun Yuan Qing-Bin Lu Jie-Ying Bai Fei Deng Geng-Fu Xiao Wei Liu Ke Peng 2019Cell Research2019,29,9:15

14Effects of seed aerosols on the growth of secondary organic aerosols from the photooxidation of toluene显示文摘Hydroxyl radical(.OH)-initiated photooxidation reaction of toluene was carried out in a self-made smog chamber.Four individualseed aerosols such as ammonium sulfate,ammonium nitrate,sodium silicate and calcium chloride,were introduced into the chamberto assess their influence on the growth of secondary organic aerosols(SOA).It was found that the low concentration of seed aerosolsmight lead to high concentration of SOA particles.Seed aerosols would promote rates of SOA formation at the start of the reaction andinhibit its formation rate with prolonging the reaction time.In the case of ca.9000 pt/cm3 seed aerosol load,the addition of sodiumsilicate induced a same effect on the SOA formation as ammonium nitrate.The influence of the four individual seed aerosols on thegeneration of SOA decreased in the order of calcium chloride>sodium silicate and ammonium nitrate>ammonium sulfate.HAO Li-qing WANG Zhen-ya HUANG Ming-qiang FANG Li ZHANG Wei-jun 2007Journal of Environmental Sciences2007,19,6:14
15Application of thyristor controlled phase shifting transformer excitation impedance switching control to suppress short-circuit fault current level显示文摘Short-circuit fault current suppression is a very important issue in modern large-interconnected power networks. Conventional short-circuit current limiters, such as superconducting fault current limiters, have to increase additional equipment investments. Fast power electronics controlled flexible AC transmission system(FACTS)devices have opened a new way for suppressing the fault current levels, while maintaining their normal functionalities for steady-state and transient power system operation and control. Thyristor controlled phase shifting transformer(TCPST) is a beneficial FACTS device in modern power systems, which is capable of regulating regional powerflow. The mathematical model for TCPST under different operation modes is firstly investigated in this study. Intuitively, the phase shifting angle control can adjust the equivalent impedance of TCPST, but the effect has been demonstrated to be weak. Therefore, a novel transformer excitation impedance switching(EIS) control method, is proposed for fault current suppressing, according to the impedance characteristics of TCPST. Simulation results on IEEE 14-bus system have shown considerable current limiting characteristic of the EIS control under various fault types. Also, analysis of the timing requirement during fault interruption, overvoltage phenomenon, and ancillary mechanical support issues during EIS control is discussed,so as to implement the proposed EIS control properly for fast fault current suppression.Jun LIU Xudong HAO Xu WANG Yefu CHEN Wanliang FANG Shuanbao NIU 2018Journal of Modern Power Systems and Clean Energy2018,6,4:14

17Control of differential tectonic evolution on petroleum occurrence in Bohai Bay Basin显示文摘The Bohai Bay Basin(BBB)is the most petroliferous Cenozoic basin in the east of China.It consists of seven depressions.Each depression has been subjected to different stress states and then has experienced varying faulting processes since the Neogene,especially during the Neotectonism(from the Pliocene to the present).On the basis of the investigation of fault patterns,fault densities and fault activity rates(FARs)for each depression,this paper demonstrates the discrepancy of faulting development and evolution across the BBB.The dynamic mechanism for the differences in faulting is also discussed by the analysis of the regional stress state.The Bozhong Depression is just situated in the transtensional zone induced by the two active strike-slip faults,namely Yingkou-Weifang and Beijing-Penglai.In this depression,the major faults which cut through the Paleogene or the Cenozoic have had higher than 10 m/Ma FARs since the Neogene,and the highest FARs have reached or exceeded 25 m/Ma during the Neotectonism.As a result,most of the petroleum has migrated along these major faults and accumulated within the Neogene.In contrast,in the other depressions of the BBB away from the Bozhong Depression,the FARs of the major faults were decreased to lower than 10 m/Ma since the Neogene,and tended to be zero during the Neotectonism.Therefore,the major faults could not serve as vertical conduits for petroleum migration,and the petroleum was entrapped in the Paleogene.Consequently,the faulting since the Neogene,especially during the Neotectonism,controlled the petroleum richness in vertical strata.TENG ChangYu ZOU HuaYao HAO Fang 2014Science China Earth Sciences2014,57,5:13
18Recurrent atrial tachycardia and atrial fribrillation after circumferential pulmonary vein ablation:What’s the difference?显示文摘Background Recurrent atrial tachyarrhythmia (ATa) after circumferential pulmonary vein ablation (CPVA) includes atrial tachycardia (AT) and atrial fribrillation (AF). However, whether there are some differences in clinical course and mechanisms between the recurrent AT and the recurrent AF remained unclear. This study was conducted to investigate the incidence, mechanism, clinical course of the recurrent AT and AF in patients under CPVA.Methods One hundred and thirty consecutive patients (M/F=95/35) with highly symptomatic and multiple antiarrhythmic drugs (AADs) refractory paroxysmal (n=91) or persistent (n=39) AF were included. The ablation protocol consisted solely of two continuous circular lesions around the ipsilateral pulmonary veins (PV) guided by CARTO system. The endpoint of CPVA is PV isolation. For patients with recurrent ATa within 2 months after the initial procedure, cardioversion with direct current was attempted if the ATa lasted for more than 24 hours. A repeat ablation procedure was performed only for patients with AADs refractory recurrent ATa and at least followed up for 2 months after the initial procedure.Results Within 2 months after the initial procedure, 52 patients (40.0%) had experienced episodes of symptomatic recurrent ATa. Among them, 23 patients (44.2%) with recurred AT alone (AT group), 14 patients (26.9%) with recurred AF alone (AF group), and 15 patients (28.8%) with recurred AT and AF (AT plus AF group). The delayed cure rate (65.2%) in AT group was significant higher than that in AF group (21.4%, P<0.05) and AF plus AT group (26.7%, P<0.05). A repeat ablation was performed in 21 patients, including 6 patients with recurrent AT alone, 8 patients with recurrent AF alone, and 7 patients with recurrent AF plus AT. The mean number of PV gaps was 1.2±0.4 in AT group, which was significantly lower than that in AF group (2.6±0.7, P<0.05) and AF plus AT group (2.0±0.6, P<0.05). Delayed cure rate and number of PV gaps between AF group and AF plus AT group were comparable (P>0.05).Conclusions Present study indicates that recurrent AT and AF after CPVA have the different clinical course and different electrophysiological findings during repeat procedure as follows: ⑴After CPVA, spontaneous resolution of recurrent ATa was mainly found in patients with recurrent AT alone (about two thirds patients). ⑵The type of recurrent ATa after CPVA is associated with the number of PV gaps.LIU Xing-peng LONG De-yong DONG Jian-zeng LIU Xiao-qing FANG Dong-ping HAO Peng MA Chang-sheng 2005Chinese Medical Journal2005,,21:13

20Ultrafast and broadband photodetectors based on a perovskite/organic bulk heterojunction for large-dynamic-range imaging显示文摘Organic-inorganic hybrid perovskite(OIHP)photodetectors that simultaneously achieve an ultrafast response and high sensitivity in the near-infrared(NIR)region are prerequisites for expanding current monitoring,imaging,and optical communication capbilities.Herein,we demonstrate photodetectors constructed by OIHP and an organic bulk heterojunction(BHJ)consisting of a low-bandgap nonfullerene and polymer,which achieve broadband response spectra up to 1μm with a highest external quantum efficiency of approximately 54%at 850 nm,an ultrafast response speed of 5.6 ns and a linear dynamic range(LDR)of 191 dB.High sensitivity,ultrafast speed and a large LDR are preeminent prerequisites for the practical application of photodetectors.Encouragingly,due to the high-dynamicrange imaging capacity,high-quality visible-NIR actual imaging is achieved by employing the OIHP photodetectors.We believe that state-of-the-art OIHP photodetectors can accelerate the translation of solution-processed photodetector applications from the laboratory to the imaging market.Chenglong Li Hailu Wang Fang Wang Tengfei Li Mengjian Xu Hao Wang Zhen Wang Xiaowei Zhan Weida Hu Liang Shen 2020Light(Science & Applications)2020,9,1:13
