1Type 2 diabetes mellitus and CA 19-9 levels显示文摘AIM:To prospectively investigate serum CA 19-9 levels in type 2 diabetic patients in comparison with age-and gender-matched control subjects. METHODS:We recorded duration of diabetes and examined fasting glucose levels,HbA1c levels and serum CA 19-9 levels in 76 type 2 diabetic patients and 76 controls.Abdominal CT was performed in order to eliminate abdominal malignancy in the diabetic and control groups. RESULTS:The average CA 19-9 level was 46.0±22.4 U/mL for diabetic patients whereas it was 9.97±7.1 U/mL for the control group(P<0.001).Regression analysis showed a positive correlation between diabetes and CA 19-9 independent from age,gender,glucose level and HbA1c level(t=8.8,P<001).Two of the diabetic patients were excluded from the study because of abdominal malignancy shown by CT at the initial evaluation.For all patients,abdominal CT showed no pancreatic abnormalities. CONCLUSION:CA 19-9 is a tumor-associated antigen, which is elevated in pancreatic,upper gastrointestinal tract,ovarian hepatocellular,and colorectal cancers,as well as in inflammatory conditions of the hepatobiliary system,biliary obstruction and in thyroid diseases. Diabetes has been claimed to be a risk factor for pancreatic cancer,which is increasing its incidence and has one of the lowest survival rates of all cancers.CA 19-9 is used in the diagnosis of pancreatic cancer but is also a marker of pancreatic tissue damage that might be caused by diabetes.We propose that a higher cut- off value of CA 19-9 should be used in diabetics to differentiate benign and malignant pancreatic disease, and subtle elevations of CA 19-9 in diabetics should be considered as the indication of exocrine pancreatic dysfunction.Oya Uygur-Bayramicli Resat Dabak Ekrem Orbay Can Dolapclo■lu Mehmet Sargin Gamze Kilico■lu Yüksel Güleryüzlü Alpaslan Mayada■li 2007World Journal of Gastroenterology2007,13,40:63

3Fields of applications,diagnostic yields and findings of OMOM capsule endoscopy in 2400 Chinese patients显示文摘AIM:To retrospectively analyze the fields of application,diagnostic yields and findings of OMOM capsule endoscopy in Chinese patients.METHODS:A database including 2400 Chinese patients who received OMOM capsule endoscopy in 27 endoscopy centers in China was retrieved from the Jianshan Science and Technology Ltd.OMOM capsule endoscopy database.The patient's age,gender,fields of application,the potentially relevant findings,pyloric transit time(PTT),small bowel transit time(SBTT),and complete small-bowel examination rate(CSER) were recorded and analyzed.RESULTS:Two thousand four hundred patients aged 9-91 years(mean,49 years),of whom 1510 were males(62.9%),underwent 2400 OMOM capsule endoscopy procedures.One thousand two hundred and thirty two(51.3%) were referred with obscure gastrointestinal bleeding(OGIB),642(26.8%) with abdominal pain,and 223(9.3%) with chronic diarrhea.The overall diagnostic yield was 47.7%(1144/2400).The diagnostic yield of OMOM capsule endoscopy in OGIB subgroup was much higher than in the non-OGIB subgroup(62.4% vs 32.1%,P<0.001).The most common findings of the small bowel in Chinese patients with OGIB were arteriovenous malformation(28.1%) and tumors(18.9%).There was no significant difference in the diagnostic yield between the male and female patients with OGIB.However,the diagnostic yield in patients aged more than 60 was higher than in patients aged less than 60(69.8% vs 58.9%,P<0.001).The median PTT was 41 min(range:1-544 min) and the mean SBTT was 247.2 ± 88.9 min.The overall CSER was 86.8%.CONCLUSION:The OMOM capsule endoscopy is a valuable tool for small bowel evaluation with good overall diagnostic yield and CSER.Liao, Zhuan Gao, Rui Li, Feng Xu, Can Zhou, Yi Wang, Jin-Shan Li, Zhao-Shen 2010World Journal of Gastroenterology2010,16,21:35
4Plasma levels of omentin-1 and visfatin in senile patients with coronary heart disease and heart failure显示文摘Objective:To investigate the alteration of plasma levels of omentin-1 and visfatin in elderly patients with coronary heart disease(CHD)and heart failure.Methods:Plasma omentin-1 and visfatin levels were measured in 90 subjects(29 stable angina pectoris(SAP)cases,30 unstable angina pectoris(UAP)cases and 31 age-and sex-matched healthy controls(age≥60 years)by enzyme-linked immunosorbent assay methods.According to the New York Heart Association classification.59 CHDs were divided into three groups:functional I class,11 cases;functional II/III class,36 cases;and functional IV class,12 cases.Results:The plasma level of omentin-1in CHO patients was significantly lower than thai of the control group.Otnenlin-lin SAP group and UAP group were significantly lower compared to the control group(there was no statistical significance between UAP group and SAP group;P>0.05).The plasma level of visfatin in CHD patients was significandy higher than that of the control group.Similarly,visfatin in SAP group and UAP group were all significantly higher compared to the control group,while there was no statistical significance between UAP group,and SAP group.The plasma omentin-1 level was negatively correlated with SBP(r=-0.264,P<0.05),positively correlated with HDL-c level(r=0.271,P<0.05);the plasma visfatin level was positively correlated with TC(r=0.292,P<0.05),negatively correlated with HDL-c level(r=-0.266,P<0.05).There was a negative correlation between plasma omentin-1 and visfatin levels(r=-0.280,P<0.05).Moreover,multiple linear stepwise regression analysis showed that omentin-1 and visfatin levels might be affected by HDL-c level.Logistic regression analysis showed that visfatin could be an independent risk factor of CHD.Conclusions:Decreased levels of omentin-1 and increased levels of visfatin may be involved in the occurrence and development of CHD.Omentin-1 and visfatin,independently,may be protective and pro-inflammatory cytokines.Additionally,both omentin-1 and visfatin may be related to lipid metabolism.Visfatin may be an independent risk factor of CHD.Xiu-Hua Wang Ling-Zhi Dou Can Gu Xiao-Qing Wang 2014Asian Pacific Journal of Tropical Medicine2014,7,1:38
5Crustal and upper mantle structure and the deep seismogenic environment in the source regions of the Lushan earthquake and the Wenchuan earthquake显示文摘Following the M w 7.9 Wenchuan earthquake, the M w 6.6 Lushan earthquake is another devastating earthquake that struck the Longmenshan Fault Zone (LFZ) and caused severe damages. In this study, we collected continuous broadband ambient noise seismic data and earthquake event data from Chinese provincial digital seismic network, and then utilized ambient noise tomography method and receiver function method to obtain high resolution shear wave velocity structure, crustal thickness, and Poisson ratio in the earthquake source region and its surroundings. Based on the tomography images and the receiver function results, we further analyzed the deep seismogenic environment of the LFZ and its neighborhood. We reveal three main findings: (1) There is big contrast of the shear wave velocities across the LFZ. (2) Both the Lushan earthquake and the Wenchuan earthquake occurred in the regions where crustal shear wave velocity and crustal thickness change dramatically. The rupture faults and the aftershock zones are also concentrated in the areas where the lateral gradients of crustal seismic wave speed and crustal thickness change significantly, and the focal depths of the earthquakes are concentrated in the transitional depths where shear wave velocities change dramatically from laterally uniform to laterally non-uniform. (3) The Wenchuan earthquake and its aftershocks occurred in low Poisson ratio region, while the Lushan earthquake sequences are located in high Poisson ratio zone. We proposed that the effect of the dramatic lateral variation of shear wave velocity, and the gravity potential energy differences caused by the big contrast in the topography and the crustal thickness across the LFZ may constitute the seismogenic environment for the strong earthquakes in the LFZ, and the Poisson ratio difference between the rocks in the south and north segments of the Longmenshan Fault zone may explain the 5 years delay of the occurrence of the Lushan earthquake than the Wenchuan earthquake.ZHENG Yong GE Can XIE ZuJun YANG YingJie XIONG Xiong HSU HouTze 2013Science China Earth Sciences2013,56,7:37
6Source parameters inversion of the 2013 Lushan earthquake by combining teleseismic waveforms and local seismograms显示文摘On April 20, 2013, a magnitude M s 7.0 earthquake occurred in Lushan, Sichuan Province, China, and caused heavy casualties and economic losses. Based on the local broadband waveforms in Sichuan and adjacent provinces regional networks and teleseismic broadband records from IRIS stations, the focal mechanism and the focal depth are determined by the CAP (Cut And Paste) and its upgraded methods, CAPtele and CAPjoint, respectively. The results show that the focal mechanisms and depth from different methods are steady, and the best double couple solution derived from the joint inversion is 210°, 44°, and 91° for strike, dip, and rake angles respectively for one nodal plane and 29°, 46°, and 89° for another with 16 km focal depth and M w 6.66 moment magnitude. In order to verify the reliability of the results, a number of tests are performed based on local seismograms with different velocity models. They indicate that there is about 10 degree's fluctuation in focal mechanisms and about 2 km variation in focal depth with a complex velocity structure. Furthermore, inverted by re-sampling the teleseismic waveforms on the basis of epicentral distance, the solutions are consistent with each other, which manifests that the teleseismic records are effective for constraining source parameters of the Lushan earthquake.XIE ZuJun JIN BiKai ZHENG Yong GE Can XIONG Xiong XIONG Cheng HSU HouTze 2013Science China Earth Sciences2013,56,7:35

9Outbreak of Dengue Fever in Central China,2013显示文摘In 2013,the first dengue fever(DF) outbreak in central China was reported in the central of Henan province,northern temperate regions,although they have been sequentially recorded in Southern China.106 suspected DF cases were reported and 73 patients were confirmed dengue virus type 3(DEN-3) infections.62/392(15.8%) local health persons showed DEN antibodies positive.To this day Henan is the northernmost province in China which has been reported about outbreak of DF and what is important is that it warns us the endemic range of DF has been expanded geographically in China.HUANG Xue Yong MA Hong Xia WANG Hai Feng DU Yan Hua SU Jia LI Xing Le TANG Xiao Yan MA Hong Peng ZU Bing Can ZHANG Qiao Hong CHEN Hao Min XU Bian Li 2014Biomedical and Environmental Sciences2014,27,11:30
10Photovoltaic and Solar Power Forecasting for Smart Grid Energy Management显示文摘Due to the challenge of climate and energy crisis,renewable energy generation including solar generation has experienced significant growth.Increasingly high penetration level of photovoltaic(PV)generation arises in smart grid.Solar power is intermittent and variable,as the solar source at the ground level is highly dependent on cloud cover variability,atmospheric aerosol levels,and other atmosphere parameters.The inherent variability of large-scale solar generation introduces significant challenges to smart grid energy management.Accurate forecasting of solar power/irradiance is critical to secure economic operation of the smart grid.This paper provides a comprehensive review of the theoretical forecasting methodologies for both solar resource and PV power.Applications of solar forecasting in energy management of smart grid are also investigated in detail.Can Wan Jian Zhao Yonghua Song Zhao Xu Jin Lin Zechun Hu 2015CSEE Journal of Power and Energy Systems2015,1,4:29
11Additive manufacturing of metals:Microstructure evolution and multistage control显示文摘As a revolutionary industrial technology,additive manufacturing creates objects by adding materials layer by layer and hence can fabricate customized components with an unprecedented degree of freedom.For metallic materials,unique hierarchical microstructures are constructed during additive manufacturing,which endow them with numerous excellent properties.To take full advantage of additive manufacturing,an in-depth understanding of the microstructure evolution mechanism is required.To this end,this review explores the fundamental procedures of additive manufacturing,that is,the formation and binding of melt pools.A comprehensive processing map is proposed that integrates melt pool energy-and geometry-related process parameters together.Based on it,additively manufactured microstructures are developed during and after the solidification of constituent melt pool.The solidification structures are composed of primary columnar grains and fine secondary phases that form along the grain boundaries.The post-solidification structures include submicron scale dislocation cells stemming from internal residual stress and nanoscale precipitates induced by intrinsic heat treatment during cyclic heating of adjacent melt pool.Based on solidification and dislocation theories,the formation mechanisms of the multistage microstructures are thoroughly analyzed,and accordingly,multistage control methods are proposed.In addition,the underlying atomic scale structural features are briefly discussed.Furthermore,microstructure design for additive manufacturing through adjustment of process parameters and alloy composition is addressed to fulfill the great potential of the technique.This review not only builds a solid microstructural framework for metallic materials produced by additive manufacturing but also provides a promising guideline to adjust their mechanical properties.Zhiyuan Liu Dandan Zhao Pei Wang Ming Yan Can Yang Zhangwei Chen Jian Lu Zhaoping Lu 2022Journal of Materials Science & Technology2022,,5:27
12Matrine attenuates oxidative stress and cardiomyocyte apoptosis in doxorubicin-induced cardiotoxicity via maintaining AMPKα/UCP2 pathway显示文摘Oxidative stress and cardiomyocyte apoptosis are involved in the pathogenesis of doxorubicin(DOX)-induced cardiotoxicity. Matrine is well-known for its powerful anti-oxidant and anti-apoptotic capacities. Our present study aimed to investigate the effect of matrine on DOX-induced cardiotoxicity and try to unearth the underlying mechanisms. Mice were exposed with DOX to generate DOX-induced cardiotoxicity or normal saline as control. H9 C2 cells were used to verify the effect of matrine in vitro.DOX injection triggered increased generation of reactive oxygen species(ROS) and excessive cardiomyocyte apoptosis, which were significantly mitigated by matrine. Mechanistically, we found that matrine ameliorated DOX-induced uncoupling protein 2(UCP2) downregulation, and UCP2 inhibition bygenipin could blunt the protective effect of matrine on DOX-induced oxidative stress and cardiomyocyte apoptosis. Besides, 50-AMP-activated protein kinase α2(Ampkα2) deficiency inhibited matrine-mediated UCP2 preservation and abolished the beneficial effect of matrine in mice. Besides, we observed that matrine incubation alleviated DOX-induced H9 C2 cells apoptosis and oxidative stress level via activating AMPKα/UCP2, which were blunted by either AMPKα or UCP2 inhibition with genetic or pharmacological methods. Matrine attenuated oxidative stress and cardiomyocyte apoptosis in DOX-induced cardiotoxicity via maintaining AMPKα/UCP2 pathway, and it might be a promising therapeutic agent for the treatment of DOX-induced cardiotoxicity.Can Hu Xin Zhang Wenying Wei Ning Zhang Haiming Wu Zhenguo Ma Lingli Li Wei Deng Qizhu Tang 2019Acta Pharmaceutica Sinica B2019,9,4:25

16Current status of surgical treatment of rectal cancer in China显示文摘With the changing lifestyle and the acceleration of aging in the Chinese population,the incidence and mortality of colorectal cancer(CRC)have risen in the last decades.On the contrary,the incidence and mortality of CRC have continued to decline in the USA since the 1980s,which is mainly attributed to early screening and standardized diagnosis and treatment.Rectal cancer accounts for the largest proportion of CRC in China,and its treatment regimens are complex.At present,surgical treatment is still the most important treatment for rectal cancer.Since the first Chinese guideline for diagnosis and treatment of CRC was issued in 2010,the fourth version has been revised in 2020.These guidelines have greatly promoted the standardization and internationalization of CRC diagnosis and treatment in China.And with the development of comprehensive treatment methods such as neoadjuvant chemoradiotherapy,targeted therapy,and immunotherapy,the post-operative quality of life and prognosis of patients with rectal cancer have improved.We believe that the inflection point of the rising incidence and mortality of rectal cancer will appear in the near future in China.This article reviewed the current status and research progress on surgical therapy of rectal cancer in China.Yong Yang Han-Yang Wang Yong-Kang Chen Jia-Jia Chen Can Song Jin Gu 2020Chinese Medical Journal2020,,22:21

18Mechanism-based anti-anxiety effects of polysaccharides extracted from Shudihuang (Radix Rehmanniae Preparata) by two-dimensional electrophoresis analysis in rat hippocampus proteins显示文摘OBJECTIVE: To investigate mechanism-based anti-anxiety effects of Shudihuang (Radix Rehmanniae Preparata) polysaccharides (RRPPs) through two-dimensional electrophoresis (2-DE) analysis with mass spectrometry (MS) of hippocampus proteins in rats treated with monosodium L-glutamate (MSG).METHODS: MSG (4 g/kg) or normal saline (NS) was injected subcutaneously into infant male rats on days 2, 4, 6, 8, 10 after birth. MSG-treated rats at 8 weeks old were given NS, diazepam, or RRPPs daily for seven consecutive days by intragastric administration, while NS-treated rats given the same volume of NS. Elevated plus maze (EPM) and light/ dark transition (LDT) tests were used to observe anti-anxiety effects of RRPPs at 1 h after the last administration. After EPM and LDT tests, hippocampus tissues were excised on ice rapidly from the brains of rats. Thereafter, 2-DE and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF/MS) were used for detecting differential proteins in hippocampus of rats so as to explore the potential mechanisms. RESULTS: RRPPs (200, 400 mg/kg) could significantly inhibit MSG-induced decrease of time and entries percentages in open zones in EPM test and numbers of light-dark transition in LDT test. Further analysis of 2-DE and MALDI-TOF/MS indicated that β-synuclein, protein DJ-1, peroxiredoxin-2, peroxiredoxin-6, dimethylarginine dimethylaminohydrolase 1 (DDAH-1) and iron-sulfur proteins were all found to be down-regulated significantly in MSG-treated rats, while such down-regulation was significantly inhibited after treatment with RRPPs. CONCLUSION: RRPPs showed anti-anxiety effects and potential mechanisms might be related to inhibiting MSG-induced down-regulation of β-synuclein, DJ-1, peroxiredoxin-2, peroxiredoxin-6, DDAH-1 and iron-sulfur proteins in hippocampus of rats.Ying Cui Chunlei Rong Junming Wang Can Cui Li Wang Zhiyi Feng Jing Feng Bing Niu 2013Journal of Traditional Chinese Medicine2013,33,4:19
19Blunt trauma related chest wall and pulmonary injuries: An overview显示文摘Physical traumas are tragic and multifaceted injuries that suddenly threaten life.Although it is the third most common cause of death in all age groups,one out of four trauma patients die due to thoracic injury or its complications.Blunt injuries constitute the majority of chest trauma.This indicates the im porta nee of chest trauma among all traumas.Blunt chest trauma is usually caused by motor vehicle accident,falling from height,blunt instrument injury and physical assault.As a result of chest trauma,many injuries may occur,such as pulm onary injuries,and these require urge nt in terve ntion.Chest wall and pulmonary injuries range from rib fractures to flail chest,pneumothorax to hemothorax and pulmonary contusion to tracheobronchial injuries.Following these injuries,patients may present with a simple dyspnea or even respiratory arrest.For such patie nt,it is imports nt to understa nd the treatme nt logic and to take a multidisciplinary approach to treat the pulmonary and chest wall injuries.This is because only 10%of thoracic trauma patients require surgical operation and the remaining 90%can be treated with simple methods such as appropriate airway,oxygen support,maneuvers,volume support and tube thoracostomy.Adequate pain control in chest trauma is sometimes the most basic and best treatment.With definite diagnosis,the morbidity and mortality can be significantly reduced by simple treatment methods.Bekir Nihat Dogrul Ibrahim Kiliccalan Ekrem Samet Asci Selim Can Peker 2020Chinese Journal of Traumatology2020,23,3:19
