1China’s urban expansion from 1990 to 2010 determined with satellite remote sensing显示文摘Based on the same data source of Landsat TM/ETM+ in 1990s,2000s and 2010s,all urban built-up areas in China are mapped mainly by human interpretation.Mapping results were checked and refined by the same analyst with the same set of criteria.The results show during the last 20 years urban areas in China have increased exponentially more than 2 times.The greatest area of urbanization changed from Northeastern provinces in 1990s to the Southeast coast of China in Jiangsu,Guangdong,Shandong,and Zhejiang in 2010s.Urban areas are mostly converted from croplands in China.Approximately 17750 km 2 croplands were converted into urban lands.Furthermore,the conversion from 2000 to 2010 doubled that from 1990 to 2000.During the 20 years,the most urbanized provinces are Jiangsu,Guangdong,Shandong and Zhejiang.We also analyzed built-up areas,gross domestic production (GDP) and population of 147 cities with a population of greater than 500000 in 2009.The result shows coastal cities and resource-based cities are with high economic efficiency per unit of built-up areas,resource-based cities have the highest population density,and the economic efficiency of most coastal provinces are lower than central provinces and Guangdong.The newly created urban expansion dataset is useful in many fields including trend analysis of urbanization in China;simulation of urban development dynamics;analysis of the relationship among urbanization,population growth and migration;studies of carbon emissions and climate change;adaptation of climate change;as well as land use and urban planning and management.WANG Lei LI CongCong YING Qing CHENG Xiao WANG XiaoYi LI XueYan HU LuanYun LIANG Lu YU Le HUANG HuaBing GONG Peng 2012Chinese Science Bulletin2012,57,22:64
2Adjuvant probiotics improve the eradication effect of triple therapy for Helicobacter pylori infection显示文摘AIM:To investigate whether the addition of probiotics can improve the eradication effect of triple therapy for Helicobacter pylori (H. pylori ) infection. METHODS:This open randomized trial recruited 234 H. pylori positive gastritis patients from seven local centers. The patients were randomized to one-week standard triple therapy (omeprazole 20 mg bid , clarithromycin 500 mg bid , and amoxicillin 1000 mg bid ; OCA group, n = 79); two weeks of pre-treatment with probiotics, containing 3 × 107 Lactobacillus acidophilus per day, prior to one week of triple therapy (POCA group, n = 78); or one week of triple therapy followed by two weeks of the same probiotics (OCAP group, n = 77). Successful eradication was defined as a negative C13 or C14 urease breath test four weeks after triple therapy. Patients were asked to report associated symptoms at baseline and during follow-up, and side effects related to therapy were recorded. Data were analyzed by both intention-to-treat (ITT) and per-protocol (PP) methods. RESULTS:PP analysis involved 228 patients, 78 in the OCA, 76 in the POCA and 74 in the OCAP group. Successful eradication was observed in 171 patients; by PP analysis, the eradication rates were significantly higher (P = 0.007 each) in the POCA (62/76; 81.6%, 95% CI 72.8%-90.4%) and OCAP (61/74; 82.4%, 95% CI 73.6%-91.2%) groups than in the OCA group (48/78; 61.5%, 95% CI 50.6%-72.4%). ITT analysis also showed that eradication rates were significantly higher in the POCA (62/78; 79.5%, 95% CI 70.4%-88.6%) and OCAP (61/77; 79.2%, 95% CI 70%-88.4%) groups than in the OCA group (48/79; 60.8%, 95% CI 49.9%-71.7%), (P = 0.014 and P = 0.015). The symptom relieving rates in the POCA, OCAP and OCA groups were 85.5%, 89.2% and 87.2%, respectively. Only one of the 228 patients experienced an adverse reaction. CONCLUSION:Administration of probiotics before or after standard triple therapy may improve H. pylori eradication rates.Yi-Qi Du Tun Su Jian-Gao Fan Yu-Xia Lu Ping Zheng Xing-Hua Li Chuan-Yong Guo Ping Xu Yan-Fang Gong Zhao-Shen Li 2012World Journal of Gastroenterology2012,18,43:54
3China's wetland change (1990-2000) determined by remote sensing显示文摘Two wetland maps for the entire China have been produced based on Landsat data acquired around 1990 and 2000. Wetlands in China have been divided into 3 broad categories with 15 sub-categories except rice fields. In 1990, the total wetland area in China was 355208 km2 whereas in 2000 it dropped to 304849 km2 with a net loss of 50360 km2. During an approximate 10-year period, inland wetland reduced from 318326 to 257922 km2, coastal wetland dropped from 14335 to 12015 km2, while artificial wetland increased from 22546 to 34911 km2. The greatest natural wetland loss occurred in Heilongjiang, Inner Mon- golia, and Jilin with a total loss of over 57000 km2 of wetland. In western China, over 13000 km2 of wetlands were newly formed in Xinjiang, Tibet, and Qinghai. About 12000 km2 of artificial wetlands were also added for fish farm and reservoir constructions. The newly formed wetlands in western China were caused primarily by climate warming over that region whereas the newly created artificial wetlands were caused by economic developments. China’s wetland loss is caused mainly by human activities.Peng Gong ZhenGuo Niu Xiao Cheng KuiYi Zhao DeMin Zhou JianHong Guo Lu Liang XiaoFeng Wang DanDan Li HuaBing Huang et al. 2010Science China Earth Sciences2010,53,7:28
4Decreased expression of serotonin in the jejunum and increased numbers of mast cells in the terminal ileum in patients with irritable bowel syndrome显示文摘AIM: To investigate if there are changes in serotonin (5-HT) levels, enterochromaffin (EC) cells and mast cells in small intestinal mucosa of patients with irritable bowel syndrome (IBS). METHODS: Diarrhea-predominant (IBS-D, n = 20), or constipation-predominant (IBS-C, n = 18) IBS patients and healthy controls (n = 20) underwent colonoscopy and peroral small intestinal endoscopy, and mucosal samples were obtained at the descending part of the duodenum, proximal end of jejunum and terminal ileum. High-performance liquid chromatography- electrochemistry and immunohistochemical methods were used to detect 5-HT content, EC cells and mast cells. RESULTS: (1) There were no differences in the number and distribution of EC cells between IBS patients and the normal group. (2) The mucosal 5-HT contents at the duodenum, jejunum and ileum in IBS-C patients were 182 ± 90, 122 ± 54, 61 ± 35 ng/mg protein, respectively, which were all lower than those in the normal group (256 ± 84, 188 ± 91, and 93 ± 45 ng/ mg protein, respectively), with a significant difference at the jejunum (P < 0.05). There were no differences in the small intestinal mucosal 5-HT contents between IBS-D patients and the normal group. The mucosal 5-HT contents at the duodenum were significantly higher than those at the ileum in the three groups (P < 0.001). (3) The numbers of mast cells in patients with IBS-C and IBS-D at the ileum were 38.7 ± 9.4 and 35.8 ± 5.5/highpower field (hpf), respectively, which were significantly more than that in the normal group (29.8 ± 4.4/hpf) (P < 0.001). There was no significant difference in the numbers of mast cells at the other two parts between IBS patients and the normal group. The numbers of mast cells in IBS-C, IBS-D, and normal groups were all significantly higher at the ileum (38.7 ± 9.4, 35.8 ± 5.5, 29.8 ± 4.4/hpf, respectively) than at the duodenum (19.6 ± 4.7, 18.5 ± 6.3, 19.2 ± 3.3/hpf, respectively, P < 0.001). CONCLUSION: The changes in the 5-HT signaling pathway at the jejunum of IBS-C patients and the increase in mast cells in patients with IBS at the terminal ileum may offer evidence to explain the pathogenesis of IBS.Shen-Hao Wang Lei Dong Jin-Yan Luo Jun Gong Lu Li Xiao-Lan Lu Shui-Ping Han 2007World Journal of Gastroenterology2007,13,45:25
5Effect of ecoimmunonutrition supports on maintenance of integrity of intestinal mucosal barrier in severe acute pancreatitis in dogs显示文摘Background One of the major causes of death in severe acute pancreatitis (SAP) is severe infection owing to bacterial translocation. Some clinical studies suggested that ecoimmunonutrition (EIN) as a new strategy had better treatment effect on SAP patients. But the experiment studies on the precise mechanism of the effect of EIN were less reported. In this study, we mainly investigated the effects of EIN on bacterial translocation in SAP model of dogs. Methods SAP was induced by retrograde infusion of 5% sodium taurocholate into the pancreatic duct in healthy hybrid dogs. The SAP dogs were supported with either parenteral nutrition (PN) or elemental enteral nutrition (EEN) or EIN. The levels of serum amylase, serum aminotransferase and plasma endotoxin were detected before and after pancreatitis induction. On the 7th day after nutrition supports, peritoneal fluid, mesenteric lymph nodes (MLN), liver, and pancreas were collected for bacterial culture with standard techniques to observe the incidence of bacterial translocation. Pathology changes of pancreas were analyzed by histopathologic grading and scoring of the severity of pancreas, and the degree of intestinal mucosal damage was assessed by measuring mucosal thickness, villus height, and crypt depth of ileum. Results Compared with PN and EEN, EIN significantly decreased the levels of serum amylase, serum aminotransferase, plasma endotoxin, and the incidence of bacterial translocation. Furthermore, compared with the others, the histology scores of inflammation in pancreas and the ileum injury (ileum mocosa thickness, villus height, and crypt depth) were significantly alleviated by EIN (P<0.05). Moreover, concerning liver function, the serum levels of alanine aminotransferase, aspartate aminotransferase and albumin were ameliorating significantly in the EIN group. Conclusion Our results suggested that EIN could maintain the integrity of intestinal mucosal barrier and reducing the incidence of bacterial translocation in SAP dogs. Early EIN was safe and more effective treatment for SAP dogs.XU Gui-fang LU Zheng GAO Jun LI Zhao-shen GONG Yan-fang 2006Chinese Medical Journal2006,,8:23

10Remimazolam benzenesulfonate anesthesia effectiveness in cardiac surgery patients under general anesthesia显示文摘BACKGROUND Sedation with propofol injections is associated with a risk of addiction,but remimazolam benzenesulfonate is a comparable anesthetic with a short elimination half-life and independence from cell P450 enzyme metabolism.Compared to remimazolam,remimazolam benzenesulfonate has a faster effect,is more quickly metabolized,produces inactive metabolites and has weak drug interactions.Thus,remimazolam benzenesulfonate has good effectiveness and safety for diagnostic and operational sedation.AIM To investigate the clinical value of remimazolam benzenesulfonate in cardiac surgery patients under general anesthesia.METHODS A total of 80 patients who underwent surgery in the Department of Cardiothoracic Surgery from August 2020 to April 2021 were included in the study.Using a random number table,patients were divided into two anesthesia induction groups of 40 patients each:remimazolam(0.3 mg/kg remimazolam benzenesulfonate)and propofol(1.5 mg/kg propofol).Hemodynamic parameters,inflammatory stress response indices,respiratory function indices,perioperative indices and adverse reactions in the two groups were monitored over time for comparison.RESULTS At pre-anesthesia induction,the remimazolam and propofol groups did not differ regarding heart rate,mean arterial pressure,cardiac index or volume per wave index.After endotracheal intubation and when the sternum was cut off,mean arterial pressure and volume per wave index were significantly higher in the remimazolam group than in the propofol group(P<0.05).After endotracheal intubation,the oxygenation index and the respiratory index did not differ between the groups.After endotracheal intubation and when the sternum was cut off,the oxygenation index values were significantly higher in the remimazolam group than in the propofol group(P<0.05).Serum interleukin-6 and tumor necrosis factor-αlevels 12 h after surgery were significantly higher than before surgery in both groups(P<0.05).The observation indices were re-examined 2 h after surgery,and the epinephrine,cortisol and blood glucose levels were significantly higher in the remimazolam group than in the propofol group(P<0.05).The recovery and extubation times were significantly lower in the remimazolam group than in the propofol group(P<0.05);there were significantly fewer adverse reactions in the remimazolam group(10.00%)than in the propofol group(30.00%;P<0.05).CONCLUSION Compared with propofol,remimazolam benzenesulfonate benefited cardiac surgery patients under general anesthesia by reducing hemodynamic fluctuations.Remimazolam benzenesulfonate influenced the surgical stress response and respiratory function,thereby reducing anesthesia-related adverse reactions.Fang Tang Jian-Min Yi Hong-Yan Gong Zi-Yun Lu Jie Chen Bei Fang Chen Chen Zhi-Yi Liu 2021World Journal of Clinical Cases2021,9,34:19
11Construction and Identification of a Human Liver Specific MicroRNA Eukaryotic Expression Vector显示文摘MiR-122 is one of the non-coding RNAs which showed its effects on the lipo-metablism,virus infection and HCC forming through regulation of liver gene expression.Its eukaryotic expression vector was constructed by using pSuper which was widely applied in the siRNA expression.The precursor of human miR-122 gene was amplified by polymerase chain reaction(PCR)from the human genomic DNA.The positive clones were screened by PCR and restriction enzyme digestion.The new expression vector of miR-122 was named pHsa-m122.PHsa-m122 and its controls were transfected to HepG2 cells.The miR-122 expression activity was evaluated by GFP122i sensor reporter plasmid through fluorescence detection and Western blot.It was shown that the fluorescence intensity of GFP122si and pHsa-m122 co-transfection group was weaker than that of the controls,so the functional activity of expressed miR-122 was detected.When HepG2 cells were co-transfected with HBV1.3 and pHsa-m122 plasmids, the results showed miR-122 may down-regulate the gene expression of HBV.The human liver specific microRNA eukaryotic expression vector of miR-122 was constructed successfully,which may facilitate further study of its function in the development of liver virus infection diseases and HCC.Shanshan Chen Ming Ni Bing Yu Tingting Lv Mengji Lu Feili Gong 2007Cellular & Molecular Immunology2007,4,6:18
12Th immune response induced by H pylori vaccine with chitosan as adjuvant and its relation to immune protection显示文摘AIM:To study the immunological protective effect of H pylori vaccine with chitosan as an adjuvant and its mechanism.METHODS:Female BALB/c mice were randomly divided into seven groups and orally immunized respectively with PBS,chitosan solution,chitosan particles,H pylori antigen,H pylori antigen plus cholera toxin(CT),H pylori antigen plus chitosan solution,H pylori antigen plus chitosan particles once a week for four weeks.Four weeks after the last immunization,the mice were challenged twice by alive H pylori(1 × 109 CFU/mL)and sacrificed.Part of the gastric mucosa was embedded in paraffin,cut into sections and assayed with Giemsa staining.Part of the gastric mucosa was used to quantitatively culture H pylori.ELISA was used to detect cytokine level in gastric mucosa and anti-H pylori IgG1,IgG2a levels in serum.RESULTS:In the groups with chitosan as an adjuvant,immunological protection was achieved in 60% mice,which was significantly higher than in groups with H pylori antigen alone and without H pylori antigen(P < 0.05 or 0.001).Before challenge,the level of IFN and IL-12 in gastric mucosa was significantly higher in the groups with chitosan as an adjuvant than in the control group and the group without adjuvant(P < 0.05 or 0.005).After challenge,the level of IFN and IL-12 was significantly higher in the groups with adjuvant than in the groups without adjuvant and antigen(P < 0.05 or 0.001).Before challenge,the level of IL-2 in gastric mucosa was not different among different groups.Afterchallenge the level of IL-2 was significantly higher in the groups with adjuvant than in the control group(P < 0.05 or 0.001).Before challenge,the level of IL-10 in gastric mucosa was significantly higher in the groups with chitosan as an adjuvant than in other groups without adjuvant(P < 0.05 or 0.01).After challenge,the level of IL-10 was not different among different groups.Before challenge,the level of IL-4 in gastric mucosa was significantly higher in the groups with chitosan as an adjuvant than in other groups without adjuvant(P < 0.05).After challenge,the level of IL-4 was significantly higher in the groups with chitosan particles as an adjuvant than in the group with CT as an adjuvant(P < 0.05),and in the group with chitosan solution as an adjuvant,the level of IL-4 was significantly higher than that in control group,non-adjuvant group and the groups with CT(P < 0.05 or 0.001).The ratio of anti-H pylori IgG2a/IgG1 in serum was significantly lower in the groups with chitosan as an adjuvant than in the groups with CT as an adjuvant or without adjuvant(P < 0.01).CONCLUSION:H pylori vaccine with chitosan as an adjuvant can protect against H pylori infection and induce both Th1 and Th2 type immune response.Yong Xie Nan-Jin Zhou Yan-Feng Gong Xiao-Jiang Zhou Jiang Chen Si-Juan Hu Nong-Hua Lu Xiao-Hua Hou 2007World Journal of Gastroenterology2007,13,10:18

16Phase 1 clinical trial demonstrated that MUC1 positive metastatic seminal vesicle cancer can be effectively eradicated by modified Anti-MUC1 chimeric antigen receptor transduced T cells显示文摘Recent progress in chimeric antigen receptor-modified T-cell(CAR-T cell) technology in cancer therapy is extremely promising, especially in the treatment of patients with B-cell acute lymphoblastic leukemia. In contrast, due to the hostile immunosuppressive microenvironment of a solid tumor, CAR T-cell accessibility and survival continue to pose a considerable challenge, which leads to their limited therapeutic efficacy. In this study, we constructed two anti-MUC1 CAR-T cell lines. One set of CAR-T cells contained SM3 single chain variable fragment(sc Fv) sequence specifically targeting the MUC1 antigen and co-expressing interleukin(IL) 12(named SM3-CAR). The other CAR-T cell line carried the SM3 sc Fv sequence modified to improve its binding to MUC1 antigen(named p SM3-CAR) but did not co-express IL-12. When those two types of CAR-T cells were injected intratumorally into two independent metastatic lesions of the same MUC1+ seminal vesicle cancer patient as part of an interventional treatment strategy, the initial results indicated no side-effects of the MUC1 targeting CAR-T cell approach, and patient serum cytokines responses were positive. Further evaluation showed that p SM3-CAR effectively caused tumor necrosis, providing new options for improved CAR-T therapy in solid tumors.Fengtao You Licui Jiang Bozhen Zhang Qiang Lu Qiao Zhou Xiaoyang Liao Hong Wu Kaiqi Du Youcai Zhu Huimin Meng Zhishu Gong Yunhui Zong Lei Huang Man Lu Jirong Tang Yafen Li Xiaochen Zhai Xiangling Wang Sisi Ye Dan Chen Lei Yuan Lin Qi Lin Yang 2016Science China(Life Sciences)2016,59,4:16
17Geographical characteristics of China’s wetlands derived from remotely sensed data显示文摘In this paper, we report the first wetland mapping of the entire China using Landsat enhanced thematic mapper plus (ETM+) data. These data were obtained from the Global Land Cover Facility at the University of Maryland spanning from 1999 to 2002. A total of 597 scenes of Landsat images were georeferenced and mosaiced. Manual image interpretation of satellite images was aided with elevation data, soil data, land cover/land use data and Google Earth. The minimum mapping unit is 10 pixel × 10 pixel, equivalent to 9 ha. The aim of our first round of mapping was only targeted at the boundary delineation of any type of wetland except those wetlands that are under agricultural use (i.e., paddy fields), which has already been well mapped by others. Our interpretation results indicate that a total of 359478 km2 of wetlands are of non-agricultural use. Among our preliminarily mapped wetland, 339353 km2 are inland wetland, 2786 km2 are non-agricultural artificial wetland, and 17609 km2 are coastal wetland. Because low-tide is rarely captured in satellite images, an under-estimation of coastal wetland is inevitable. We conducted some statistics based on our mapped wetlands and compared them with those previously obtained from a number of sources including a land cover/land use map made with satellite images during the late 1990s and early 2000s, a marshland map developed in approximately the same period, survey data of coastal wetland in early 1980s, and area data for approximately 400 larger patches of marshland in China compiled in 1996. Because some inconsistencies exist in the guidelines of those different wetland surveys, difference in area is expected. Some further comparison indicates that the wetland distributions derived from the preliminary wetland map are reasonable and more objective than other sources. The mapping process also indicated that the method adopted by us was efficient and cost-effective. We also found that in order to ensure comparability of the wetland maps developed at different times, a set of standard guidelines on the wetland categories to be mapped, and the mapping methods to be used must be well conceived, developed and effectively employed. We carried out some initial geographical analysis on the distribution of wetlands.NIU ZhenGuo GONG Peng CHENG Xiao GUO JianHong WANG Lin HUANG HuaBing SHEN ShaoQing WU YunZhao WANG XiaoFeng WANG XianWei YING Qing LIANG Lu ZHANG LiNa WANG Lei YAO Qian YANG ZhenZhong GUO ZiQi DAI YongJiu 2009Science China Earth Sciences2009,52,6:15
18Relation of abnormal gallbladder arterioles to gallbladder emptying in patients with gallstone and diabetes mellitus显示文摘BACKGROUND: Diabetes mellitus is thought to be related to gallstone formation in emptying the gallbladder. Diabe- tes mellitus may lead to many changes in microarterioles and micronerves; the aim of this study was to investigate the abnormality of arterioles in the gallbladder and its rela- tion to gallbladder hypomotility in patients with gallstone and diabetes mellitus. METHODS: Thirty patients with simple gallstones and 30 patients with gallstones and diabetes mellitus were analy- zed , and their gallbladder emptying function was measured with B ultrasound before operation. After operation, the arterioles of the gallbladder rinsed with periodic acid-schiff (PAS) reagent in photos were used for analysis of the tu- blar area and stereo system with the Beihang CM-2000B biological and medical photo system. RESULTS: In patients with gallstones and diabetes mellitus, the gallbladder emptying function was significantly im- paired, the area ratio of the arteriole wall to whole arte- rioles in cross section was significantly higher than that in patients with simple gallstones (0.81 ±0.09 vs. 0.58±0.15, P < 0. 01), and the average sound density was also higher (0.41 ±0.07 vs. 0.30 ±0.12, P<0.01) in patients with gall- stones and diabetes mellitus than in those with simple gall- stones. The size of arterioles (diameter) was not signifi- cantly related to the area ratio (P >0.05). CONCLUSION: In patients with diabetes mellitus, the se- dimentation of PAS positive material in the wall of arte- rioles leads to the stenosis of arterioles. It is probably con- tributive to hypomotility of the gallbladder.Xiong Ding, Jian-Ping Gong, Chang-You Lu, Chang-An Liu, Yu-Jun Shi and Gen-Wu Gao Chongqing, China Department of Hepatobiliary Surgery, Second Clinical College, Chongqing University of Medical Science, Chongqing 400010, China 2004Hepatobiliary & Pancreatic Diseases International2004,3,2:15
19Analysis and Evaluation of Nutritional Quality in Chinese Radish (Raphanus sativus L.)显示文摘Radish (Raphanus sativus L.) is an important vegetable crop worldwide. High nutritional quality was critical in itsgenetic improvement and production. The nutritional quality of 42 Chinese radish cultivars was analyzed in this study.The contents of six nutritional facts, dry matter (DM), crude fiber (CF), total soluble sugar (TSS), vitamin C (VC), protein,and nitrate, ranged from 29.7 to 88.2, 4.507 to 18.546, 2.233 to 15.457, 0.1416 to 0.3341, 0.34 to 1.15, and 1.81 to 5.89 g kg-1 freshweight (FW), respectively. Significant differences among the 42 radish cultivars were detected in the contents of nutritionalfacts. The data were subjected to cross-correlation analysis and principal component analysis (PCA). It was found that DMcontent was positively correlated with the content of TSS (r = 0.7104), VC (r = 0.4011) and protein (r = 0.4120). Vitamin C (VC)content of radish showed a positive correlation (r = 0.3300) with the protein content. According to the principal componentanalysis, out of the 42 radish cultivars, Nau-17, Nau-28, Nau-6, Nau-11, Nau-10, Nau-27, and Nau-31 were detected with veryhigh scores in comprehensive evaluation. It could be concluded that abundant diversity of nutritional fact content occurredin different radish genotypes, and PCA analysis was effective for selecting radish germplasm with high quality. The resultscould contribute useful knowledge of nutritional quality, and provide important germplasms for the elite cultivar developmentand the inheritance study of nutritional facts in radish.LU Zhao-liang LIU Li-wang LI Xiao-yan GONG Yi-qin HOU Xi-lin ZHU Xian-wen YANG Jin-lan WANG Long-zhi 2008Agricultural Sciences in China2008,7,7:15
