| 5 | Effect of mild moxibustion on intestinal microbiota and NLRP6 inflammasome signaling in rats with post-inflammatory irritable bowel syndrome显示文摘BACKGROUND About one-third of refractory irritable bowel syndrome(IBS)cases are caused by gastrointestinal(GI)infection/inflammation,known as post-infectious/postinflammatory IBS(PI-IBS).Although it is known that intestinal microbiota and host NOD-like receptor family pyrin domain containing 6(NLRP6)inflammsome signaling are closely related to PI-IBS and moxibustion has a therapeutic effect on PI-IBS,whether moxibustion regulates the intestinal flora and host NLRP6 events in PI-IBS remains unclear.AIM To examine the regulatory effect of moxibustion on intestinal microbiota and host NLRP6 inflammatory signaling in PI-IBS.METHODS Sprague-Dawley rats were divided into a normal control group,a model control group,a mild moxibustion group,and a sham mild moxibustion group.PI-IBS rats in the mild moxibustion group were treated with moxibusiton at bilateral Tianshu(ST 25)and Zusanli(ST36)for 7 consecutive days for 10 min each time.The sham group rats were given the same treatment as the mild moxibustion group except the moxa stick was not ignited.Abdominal withdrawal reflex(AWR)score was measured to assess the visceral sensitivity,and colon histopathology and ultrastructure,colonic myeloperoxidase(MPO)activity,and serum C-reactive protein(CRP)level were measured to evaluate low-grade colonic inflammation in rats.The relative abundance of selected intestinal bacteria in rat feces was detected by 16S rDNA PCR and the NLRP6 inflammsome signaling in the colon was detected by immunofluorescence,qRTPCR,and Western blot.RESULTS The AWR score was significantly decreased and the low-grade intestinal inflammation reflected by serum CRP and colonic MPO levels was inhibited in the mild moxibustion group compared with the sham group.Mild moxibustion remarkably increased the relative DNA abundances of Lactobacillus,Bifidobacterium,and Faecalibacterium prausnitzii but decreased that of Escherichia coli in the gut of PI-IBS rats.Additionally,mild moxibustion induced mRNA and protein expression of intestine lectin 1 but inhibited the expression of IL-1β,IL-18,and resistance-like moleculeβby promoting the NLRP6 and reducing the mRNA and protein expression of apoptosis-associated speck-like protein containing CARD(ASC)and cysteinyl-aspartate-specific proteinase 1(Caspase-1).The relative DNA abundances of Lactobacillus,Bifidobacteria,Faecalibacterium prausnitzii,and Escherichia coli in each group were correlated with the mRNA and protein expression of NLRP6,ASC,and Caspase-1 in the colon.CONCLUSION These findings indicated that mild moxibustion can relieve low-grade GI inflammation and alleviate visceral hypersensitivity in PI-IBS by regulating intestinal microbes and controlling NLRP6 inflammasome signaling. | Chun-Hui Bao Chun-Ye Wang Guo-Na Li Yi-Lu Yan Di Wang Xiao-Ming Jin Lu-Yi Wu Hui-Rong Liu Xiao-Mei Wang Zheng Shi Huan-Gan Wu | 2019 | World Journal of Gastroenterology2019，25，32： | 45 |

| 8 | Environmental connections of novel avian-origin H7N9 influenza virus infection and virus adaptation to the human显示文摘A novel H7N9 influenza A virus has been discovered as the causative identity of the emerging acute respiratory infection cases in Shanghai,China.This virus has also been identified in cases of infection in the neighboring area Hangzhou City in Zhejiang Province.In this study,epidemiologic,clinical,and virological data from three patients in Hangzhou who were confirmed to be infected by the novel H7N9 influenza A virus were collected and analyzed.Human respiratory specimens and chicken feces from a contacted free market were tested for influenza virus by real-time reverse transcription PCR(RT-PCR) and sequencing.The clinical features of the three cases were similar featured with high fever and severe respiratory symptoms;however,only one of the patients died.A certain degree of diversity was observed among the three Hangzhou viruses sequenced from human samples compared with other reported H7N9 influenza A viruses.The sequences of the novel avian-origin H7N9 influenza viruses from Hangzhou City contained important amino acid substitutions related to human adaptation.One of the Hangzhou viruses had gained a novel amino acid substitution(Q226I) in the receptor binding region of hemagglutinin.More importantly,the virus sequenced from the chicken feces had a 627E substitution in the PB2 protein instead of the mammalian-adapted 627K substitution that was found in the PB2 proteins from the Hangzhou viruses from the three patients.Therefore,the newly-emerging H7N9 virus might be under adaptation pressure that will help it 'jump' from avian to human hosts.The significance of these substitutions needs further exploration,with both laboratory experiments and extensive field surveillance. | LI Jun YU XinFen PU XiaoYing XIE Li SUN YongXiang XIAO HaiXia WANG FenJuan DIN Hua WU Ying LIU Di ZHAO GuoQiu LIU Jun PAN JingCao | 2013 | Science China(Life Sciences)2013，56，6： | 32 |

| 10 | Effect of bax,bcl-2 and bcl-xL on regulating apoptosis in tissues of normal liver and hepatocellular carcinoma显示文摘AIM: To investigate the expression of bax, bcl-2 and bcl-xL mRNA in the tissues of normal liver and hepatocellular carcinoma (HCC), and analyze the relationship between the expression of bax, bcl-2 and bcl-xL mRNA and clinical parameters of HCC patients.METHODS: The expression of bax, bcl-2 and bcl-xL mRNA of normal liver and HCC was measured by Northern blot. Statistical analyses were made by t test and correlation analysis.RESULTS: A very low mRNA level was indicated at bax,bcl-2 and bcl-xL in the HCC tissues in contrast to the tissues of normal liver by Northern blot analysis. The analyses of mRNA level revealed that HCC tissues exhibited a mean 7.6-fold decrease in bax, 4.2-fold in bcl-2 and 3.5-fold in bcl-xL in comparison with normal control tissues, respectively. Positive correlation was found between bax and bcl-xL (r=0.7061,P<0.01). There was no significance between the mRNA expression of these three genes and age, gender, tumor differentiation and tumor stage of HCC patients. CONCLUSION: The results are consistent with the fact that apoptosis rarely occurs in normal livers but increases in HCC, indicating that bcl-2 and bcl-xL may play a very important role in regulating the apoptosis of normal liver and HCC. | Xiao-Zhong Guo Xiao-Dong Shao Min-Pei Liu Jian-Hua Xu Li-Nan Ren Jia-Jun Zhao Hong-Yu Li Di Wang,Department of Gastroenterology,General Hospital of Shenyang Military Region,Shenyang 110016,Liaoning Province,China | 2002 | World Journal of Gastroenterology2002，8，6： | 34 |
| 11 | Postharvest Treatment with β-Aminobutyric Acid Induces Resistance Against Dry Rot Caused by Fusarium sulphureum in Potato Tuber显示文摘The effectiveness of postharvest β-aminobutyric acid (BABA) treatment was studied for inducing resistance against dry rot caused by Fusarium sulphureum in tubers and slices of two potato cultivars (resistant cultivar Shepody and susceptible cultivar Xindaping). The results showed that BABA at 100 mmol L-1 significantly reduced lesion diameter in inoculated both tubers and slices. The chemical at 100 mmol L-1 showed an effective reduction in infection ability of F. sulphureum inoculated 48 and 72 h after treatment in slices of resistant cultivar, and 72 and 96 h in susceptible ones. BABA increased the activitives of peroxidase (POD), polyphenoloxidase (PPO) and phenylalanine ammonialyase (PAL), and accumulated the contents of lignin, flavonoids and phenolics in slices. The resistant cultivar had a stronger resistant response than the susceptible one. These findings suggest that the BABA treatment can induce the resistance in potato tubers, however, the inducing degree depends on the original level of resistance present in each cultivar. | YIN Yan LI Yong-cai BI Yang CHEN Song-jiang LI Ying-chao YUAN Li WANG Yi WANG Di | 2010 | Agricultural Sciences in China2010，9，9： | 24 |

| 13 | Incidence and mortality of esophagus cancer in China, 2008-2012显示文摘Objective: To analyze the incidence and mortality rates of esophagus cancer in China from 2008 to 2012.Methods: Incident and mortality cases of esophagus cancer were retrieved from the National Central Cancer Registry(NCCR) database collecting from 135 cancer registries in China during 2008-2012. The incidence and mortality rates of esophagus cancer were calculated by area(urban/rural), region(eastern, middle, western), gender and age group(0, 1-4, 5-84 by 5 years and 85+ years). China census in 2000 and Segi’s world population were applied for age-standardized rates. Joinpoint model was used for time-trend analysis.Results: The crude incidence rate of esophagus cancer was 22.57/100,000. The age-standardized incidence rates by China standard population(ASIRC) and by world standard population(ASIRW) were 14.58/100,000 and14.80/100,000, respectively. The crude mortality rate of esophagus cancer was 17.19/100,000. The agestandardized mortality rates by Chinese standard population(ASMRC) and by world standard population(ASMRW) were 10.80/100,000 and 10.86/100,000 respectively. Incidence and mortality rates of esophagus cancer were higher in males than in females and higher in rural areas than in urban areas. The crude incidence rate in middle areas was the highest among all areas, followed by western areas and eastern areas. The age-specific incidence rate of esophagus cancer was relatively low in age groups before 40 years old and then increased after 45 years old. It peaked in the age group of 80-84 years. The patterns of age-specific mortality rates of esophagus cancer were close to those of age-specific incidence rates. The ASIRC of esophagus cancer decreased dramatically by 29.87% between 2003 and 2012, from 14.33/100,000 to 10.05/100,000. The esophagus cancer incidence rate decreased by 3.76% per year(P>0.05). The mortality rate of esophagus cancer decreased annually over the decades from 2003 to 2012 in China(P>0.05). In females, the annual percentage change(APC) of mortality rate was-5.43%[95% confidence intervals(95% CI):-6.50%,-4.30%](P<0.05) and the mortality rate of esophagus cancer in rural females was statistically significant(APC:-3.20%, 95% CI:-4.20%,-2.20%)(P<0.05).Conclusions: The focus of prevention and treatment for esophagus cancer is strengthening primary prevention of esophageal cancer, and promoting esophagus cancer secondary prevention to reduce incidence and mortality rates of esophagus cancer, prolong survival rate of patients and decline the burden of esophagus cancer in China. | Yutong He Daojuan Li Baoen Shan Di Liang Jin Shi Wanqing Chen Jie He | 2019 | Chinese Journal of Cancer Research2019，31，3： | 24 |
| 14 | SHRIMP U-Pb Zircon Geochronology of the Xiaotongguanshan and Shatanjiao Intrusions and Its Petrological Implications in the Tongling Area, Anhui显示文摘This paper determines the crystallization ages of the Xiaotongguanshan quartz monzodiorite and Shatanjiao quartz monzonite porphyry from the Tongling area using the SHRIMP zircon U-Pb method. The crystallization age of the former is 142.8±1.8 Ma; that of the latter is 151.8±2.6 Ma. These data indicate that they were formed during the Late Jurassic (142.8 to 151.8 Ma). Zoned magma chamber was formed because of double diffusive convection. Therefore, the intrusive sequence of magma is generally from quartz monzonite through quartz monzodiorite to pyroxene monzodiorite, i.e. an inverted sequence. | DI Yongjun WU Ganguo ZHANG Da SONG Biao ZANG Wenshuan ZHANG Zhongyi LI Jinwen | 2005 | Acta Geologica Sinica(English Edition)2005，79，6： | 22 |
| 15 | Incidence and mortality rate of esophageal cancer has decreased during past 40 years in Hebei Province,China显示文摘Background:Hebei province is located in North of China with of approximately 6% of whole national population.It is known as a high-risk area for esophageal cancer in China and worldwide.The aim of our study was to estimate the esophageal cancer burden and trend in Hebei Province.Methods:Eight cancer registries in Hebei Province submitted cancer registry data to the Hebei Provincial Cancer Registry Center.All data were qualified and compiled for cancer statistics in 2011.The pooled data were stratified by gender and age group(0,1-4,5-9,10-14…80+).Incidence and mortality rates were age-standardized to World Segi's population standard and expressed per 100,000 persons.In addition,proportions and cumulative incidence/mortality rates for esophageal cancer were calculated.Esophageal cancer mortality data during the periods 1973-1975,1990-1992,and 2004-2005 were extracted from the national death surveys.Mortality and incidence rate data from Cixian and Shexian were obtained from population-based cancer registries in each county.Results:The estimated number of newly diagnosed esophageal cancer cases and deaths in 2011 in Hebei Province was 24,318 and 18,226,respectively.The crude incidence rate of esophageal cancer was 33.37/100,000(males,42.18/100,000 and females,24.31/100,000).The age-standardized rate by world standard population(ASRW) was 28.09/100,000,ranking third among all cancers.The esophageal cancer mortality rate was 25.01/100,000(males,31.40/100,000 and females,18.45/100,000),ranking third in deaths among all cancers.The mortality rates of esophageal cancer displayed a significant decreasing trend in Hebei Province from 1973-1975(ASRW =48.69/100,000) to 2004-2005(ASRW =28.02/100,000),with a decreased rate of 42.45%.In Cixian,the incidence of esophageal cancer decreased from 250.76/100,000 to 106.74/100,000 in males and from 153.86/100,000 to 75.41/100,000 in females,with annual percentage changes(APC) of 2.13 and 2.16,while the mortality rates declined with an APC of 2.46 for males and 3.10 for females from 1988 to 2011.In Shexian,the incidence rate decreased from 116.90/100,000 to 74.12/100,000 in males and from 46.98/100,000 to 40.64/100,000 in females,while the mortality rates declined,with an APC of 4.89 in males from 2003 to 2011.Conclusions:Although the incidence and mortality rates of esophageal cancer remain high,an obvious decreasing trend has been observed in Hebei Province,as well as in high-risk regions,such as Cixian and Shexian,over the past 40 years. | Yutong He Yan Wu Guohui Song Yongwei Li Di Liang Jing Jin Denggui Wen Baoen Shan | 2015 | Chinese Journal of Cancer Research2015，27，6： | 22 |
| 16 | Epidemiology of Diabetes in Adults Aged 35 and Older from Shanghai,China显示文摘Objective This study aimed to investigate the epidemiology of diabetes in adults from Shanghai, aged 35 and older, in 2013. Methods We estimated the diabetes prevalence in a representative sample of 18,736 adults who were selected through a multistage stratified cluster sampling process. A standard questionnaire containing questions about demographic characteristics and lifestyle factors was distributed. After an overnight fast of at least 10 hours, a venous blood sample was collected from each participant. For each patient without a history of diabetes, another blood sample was drawn 120 min after an oral glucose tolerance test to identify undiagnosed diabetes and prediabetic condition. Results Among Shanghai residents aged 35 and above, the overall weighted prevalence of diabetes was 17.6% [95% confidence interval(CI): 16.4%-18.8%]. The prevalences were 19.3% in men and 15.8% in women as well as 19.1%, 15.4%, and 16.1% in urban, suburban, and rural residents, respectively. In addition, the weighted prevalence of prediabetes was 16.5%(95% CI: 15.3%-17.8%), with the prevalences of 16.5% in men, 16.6% in women, 15.2% in urban residents, 18.0% in suburban residents, and 18.5% in rural residents. Among all patients with diabetes, 68.1%(95% CI: 64.3%-71.6%) were aware of their status, 63.5%(95% CI: 60.0%-66.9%) received diabetes treatment, but only 35.1%(95% CI: 32.4%-37.8%) had adequate glycemic control. Conclusion In Shanghai, diabetes and prediabetes are highly prevalent. However, 1/3rd of diabetes cases are undiagnosed, and the rate of glycemic control is low. | RUAN Ye YAN Qing Hua XU Ji Ying YANG Qun Di YAO Hai Hong LI Rui SHI Yan | 2016 | Biomedical and Environmental Sciences2016，29，6： | 22 |
| 17 | Cell–cell contact with proinflammatory macrophages enhances the immunotherapeutic effect of mesenchymal stem cells in two abortion models显示文摘Mesenchymal stem cells(MSCs),which are pluripotent cells with immunomodulatory properties,have been considered good candidates for the therapy of several immune disorders,such as inflammatory bowel diseases,concanavalin A-induced liver injury,and graft-versus-host disease.The embryo is a natural allograft to the maternal immune system.A successful pregnancy depends on the timely extinction of the inflammatory response induced by embryo implantation,followed by the switch to a tolerant immune microenvironment in both the uterus and the system.Excessive infiltration of immune cells and serious inflammatory responses are triggers for embryo rejection,which results in miscarriage.Here,we demonstrated that adoptive transfer of MSCs could prevent fetal loss in a lipopolysaccharide(LPS)-induced abortion model and immune response-mediated spontaneous abortion model.The immunosuppressive MSCs alleviated excessive inflammation by inhibiting CD4+T cell proliferation and promoting the decidual macrophage switch to M2 in a tumor necrosis factor-stimulated gene-6(TSG-6)-dependent manner.Cell-tocell contact with proinflammatory macrophages increased the TSG-6 production by the MSCs,thereby enhancing the suppressive regulation of T cells and macrophages.Moreover,proinflammatory macrophages in contact with the MSCs upregulated the expression of CD200 on the stem cells and facilitated the reprogramming of macrophages towards an anti-inflammatory skew through the interaction of CD200 with CD200R on proinflammatory macrophages.Therefore,the results demonstrate that a TSG-6-mediated paracrine effect,reinforced by cell-to-cell contact between MSCs and proinflammatory macrophages,is involved in the mechanism of MSC-mediated abortion relief through the induction of immune tolerance.Our study also indicates the potential application of MSCs in clinical recurrent miscarriages. | Yanhong Li Di Zhang Ling Xu Lin Dong Ji Zheng Yikong Lin Jiefang Huang Yanyun Zhang Yu Tao Xingxing Zang Dajin Li Meirong Du | 2019 | Cellular & Molecular Immunology2019，16，12： | 23 |
| 18 | Spatial-temporal Characteristics of Land Use Intensity of Coastal Zone in China During 2000–2010显示文摘Based on remote sensing and GIS techniques, land use maps in 2000, 2005 and 2010 in China′s coastal zone were produced, and structural raster data of land use were further generated to calculate land use intensity comprehensive index(LUICI) for analyzing land use spatial-temporal characteristics at 1 km scale. Results show that: 1) from the perspective of spatial patterns of landforms at a macro scale, there is a significant difference in land use intensity between the north and the south of China′s coastal zone. Hotspots of changes mainly concentrated in metropolitan areas, estuaries and coastal wetlands; 2) elevation is an important factor that controlling land use spatial patterns at local scale. Land use intensity is much higher within areas below the elevation of 400 m and it decreased significantly as the elevation increasing; 3) there is a significant land-ocean gradient for land use intensity, which is low in island and near-shore areas, but high in the regions that 4–30 km far away the coastline because of much intensive human activities; however, in recent decades land use intensity had been promoted significantly in low near-shore area due to extensive sea reclamations; 4) significant differences of land use intensity were also found among provincial administrative units. A rising trend of land use intensity was found in provincial-level administrative units from 2000 to 2010. To sum up, elevation, land-ocean gradient, socio-economic status and policy are all influencing factors to the spatial patterns and temporal variations of land use intensity in China′s coastal zone. | DI Xianghong HOU Xiyong WANG Yuandong WU Li | 2015 | Chinese Geographical Science2015，25，1： | 20 |
| 19 | Neuroprotective effects of ginsenoside Rg1-induced neural stem cell transplantation on hypoxic-ischemic encephalopathy显示文摘Ginsenoside Rg1 is the major pharmacologically active component of ginseng,and is reported to have various therapeutic actions.To determine whether it induces the differentiation of neural stem cells,and whether neural stem cell transplantation after induction has therapeutic effects on hypoxic-ischemic encephalopathy,we cultured neural stem cells in 10–80 μM ginsenoside Rg1.Immunohistochemistry revealed that of the concentrations tested,20 m M ginsenoside Rg1 had the greatest differentiation-inducing effect and was the concentration used for subsequent experiments.Whole-cell patch clamp showed that neural stem cells induced by 20 μM ginsenoside Rg1 were more mature than non-induced cells.We then established neonatal rat models of hypoxic-ischemic encephalopathy using the suture method,and ginsenoside Rg1-induced neural stem cells were transplanted via intracerebroventricular injection.These tests confirmed that neural stem cells induced by ginsenoside had fewer pathological lesions and had a significantly better behavioral capacity than model rats that received saline.Transplanted neural stem cells expressed neuron-specific enolase,and were mainly distributed in the hippocampus and cerebral cortex.The present data suggest that ginsenoside Rg1-induced neural stem cells can promote the partial recovery of complicated brain functions in models of hypoxic-ischemic encephalopathy. | Ying-bo Li Yan Wang Ji-ping Tang Di Chen Sha-li Wang | 2015 | Neural Regeneration Research2015，10，5： | 20 |
