| 5 | Surveillance-based evidence:elimination of schistosomiasis as a public health problem in the Peoples’Republic of China显示文摘Background:A steady progress on schistosomiasis control in the Peoples’Republic of China(P.R.China)was achieved and broadened into the twelve-year medium and long term national plan(MLNP)which marled the implementation of an integrated control strategy across all endemic areas in P.R.China in 2004.To understand the endemic trends of schistosomiasis to assess the effectiveness of an integrated strategy,we conducted an analysis of schistosomiasis surveillance data spanned from 2005 to 2015.Methods:The schistosomiasis sentinel surveillance data from sentinel sites were collected and analyzed from 2005 to 2015.In these sentinel sites,residents aged 6 years or above were screened annually by indirect hemagglutination assay(IHA),while only antibody positives were followed by stool examination either Kato-katz method(KK)and/or hatching technique(HT).Domestic animals raised in sentinel sites were examined by HT for confirming the infection of schistosomes.Snail investigation was conducted each year through systematic sampling method combined with environmental sampling method.The snails collected from field were tested by microscopic dissection method.The infection rates of schistosomes in residents,domestic animals and snails,as well as the indicators reflecting the snails’distribution were calculated and analyzed.ANOVA analysis was used to examine the changes of the number of eggs per gram feces in population and Chi-square test was used to examine any change in proportions among groups.Results:A total of 148902 residents from sentinel sites attended this study and 631676 blood samples were examined by IHA test during the 11 covered years.The annual average antibody positive rates presented a significant decrease trends,from 17.48%(95%CI:17.20–17.75%)in 2005 to 5.93%(95%CI:5.71–6.15%)(χ2=8890.47,P<0.001)in 2015.During 2005–2015,the average infection rate of schistosomes in residents declined from 2.07%(95%CI:1.96–2.17%)to 0.13%(95%CI:0.09–0.16%),accompanied by significant decrease of infection intensity in population.In 2015,the stool positives were only found in farmers,fishermen and boatmen with infection rate of 0.16%(95%CI:0.11–0.20%),0.17%(95%CI:0–0.50%)respectively.The infection rate of schistosomes in domestic animals dropped from 9.42%(538/5711,95%CI:8.66–10.18%)to 0.08%(2/2360,95%CI:0–0.20%)from 2005 to 2015.Infections were found in eight species of domestic animals at the beginning of surveillance while only two cattle were infected in 2015.Totally 98 ha of new snail habitats were found,while 94.90%(93/98)distributed in lake and marshland regions.The percentage of frames with snails decreased from 16.96%(56884/335391,95%CI:16.83–17.09%)in 2005 to 4.28%(18121/423755,95%CI:4.22–4.34%)in 2014,with a slightly increase in 2015.Meanwhile,the infection rate of schistosomes in snails was decreased from 0.26%(663/256531,95%CI:0.24–0.28%)to zero during 2005–2015.Conclusions:The infection rate of schistosomes declined significantly,providing evidence that the goal of the MLNP was achieved.Elimination of schistosomiasis as a public health problem defined as WHO was also reached in P.R.China nationwide.Surveillance-response system should be improved and strengthened to realize the final goal of schistosomiasis elimination. | Jing Xu Shi-Zhu Li Li-Juan Zhang Robert Bergquist Hui Dang Qiang Wang Shan Lv Tian-Ping Wang Dan-Dan Lin Jian-Bing Liu Guang-Hui Ren Kun Yang Yang Liu Yi Dong Shi-Qing Zhang Xiao-Nong Zhou | 2020 | Infectious Diseases of Poverty2020，9，3： | 20 |
| 6 | Characterization of drug responses of mini patient-derived xenografts in mice for predicting cancer patient clinical therapeutic response显示文摘Background:Patient-derived organoids and xenografts(PDXs)have emerged as powerful models in functional diag-nostics with high predictive power for anticancer drug response.However,limitations such as engraftment failure and time-consuming for establishing and expanding PDX models followed by testing drug efficacy,and inability to subject to systemic drug administration for ex vivo organoid culture hinder realistic and fast decision-making in selecting the right therapeutics in the clinic.The present study aimed to develop an advanced PDX model,namely MiniPDX,for rapidly testing drug efficacy to strengthen its value in personalized cancer treatment.Methods:We developed a rapid in vivo drug sensitivity assay,OncoVee®MiniPDX,for screening clinically relevant regimens for cancer.In this model,patient-derived tumor cells were arrayed within hollow fiber capsules,implanted subcutaneously into mice and cultured for 7 days.The cellular activity morphology and pharmacokinetics were systematically evaluated.MiniPDX performance(sensitivity,specificity,positive and negative predictive values)was examined using PDX as the reference.Drug responses were examined by tumor cell growth inhibition rate and tumor growth inhibition rate in PDX models and MiniPDX assays respectively.The results from MiniPDX were also used to evaluate its predictive power for clinical outcomes.Results:Morphological and histopathological features of tumor cells within the MiniPDX capsules matched those both in PDX models and in original tumors.Drug responses in the PDX tumor graft assays correlated well with those in the corresponding MiniPDX assays using 26 PDX models generated from patients,including 14 gastric cancer,10 lung cancer and 2 pancreatic cancer.The positive predictive value of MiniPDX was 92%,and the negative predictive value was 81%with a sensitivity of 80%and a specificity of 93%.Through expanding to clinical tumor samples,Min-iPDX assay showed potential of wide clinical application.Conclusions:Fast in vivo MiniPDX assay based on capsule implantation was developed-to assess drug responses of both PDX tumor grafts and clinical cancer specimens.The high correlation between drug responses of paired MiniPDX and PDX tumor graft assay,as well as translational data suggest that MiniPDX assay is an advanced tool for personalized cancer treatment. | Feifei Zhang Wenjie Wang Yuan Long Hui Liu Jijun Cheng Lin Guo Rongyu Li Chao Meng Shan Yu Qingchuan Zhao Shun Lu Lili Wang Haitao Wang Danyi Wen | 2018 | Cancer Communications2018，38，1： | 20 |

| 8 | Effectiveness of Different Waist Circumference Cut-off Values in Predicting Metabolic Syndrome Prevalence and Risk Factors in Adults in China显示文摘Objective To study the effectiveness of waist circumference cut-off values in predicting the prevalence of metabolic syndrome(MetS) and risk factors in adults in China. Methods A cross-sectional survey was condcuted in 14 provinces(autonomous region, municipality) in China. A total of 47 325 adults aged ≥20 years were selected by multistage stratified sampling, and questionnaire survey and physical and clinical examination were conducted among them. MetS was defined according to the International Diabetes Federation(IDF) criteria and modified IDF criteria.Results The age-standardized prevalence of MetS was 24.2%(22.1% in men and 25.8% in women) and 19.5%(22.1% in men and 18.0% in women) according to the IDF criteria and modified IDF criteria respectively. The age-standardized prevalence of pre-MetS was 8.1%(8.6% in men and 7.8% in women) according to the modified IDF criteria. The prevalence of MetS was higher in urban residents than rural residents and in northern China residents than in southern China residents. The prevalence of central obesity was about 30% in both men and women according to the ethnicity-specific cut-off values of waist circumference for central obesity(90 cm for men and 85 cm for women). Multivariate regression analysis revealed no significant difference in risk factors between the two MetS definitions. Conclusion Using both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China. | ZHOU Hai Cheng LAI Ya Xin SHAN Zhong Yan JIA Wei Ping YANG Wen Ying LU Ju Ming WENG Jian Ping JI Li Nong LIU Jie TIAN Hao Ming JI Qiu He ZHU Da Long CHEN Li GUO Xiao Hui ZHAO Zhi Gang Li Qiang ZHOU Zhi Guang GE Jia Pu SHAN Guang Liang | 2014 | Biomedical and Environmental Sciences2014，27，5： | 17 |
| 9 | Simulation of particle flow in a bell-less type charging system of a blast furnace using the discrete element method显示文摘A three-dimensional model was established by the discrete element method(DEM) to analyze the flow and segregation of particles in a charging process in detail.The simulation results of the burden falling trajectory obtained by the model were compared with the industrial charging measurements to validate the applicability of the model.The flow behavior of particles from the weighing hopper to the top layer of a blast furnace and the heaping behavior were analyzed using this model.A radial segregation index(RSI)was used to evaluate the extent of the size segregation in the charging process.In addition,the influence of the chute inclination angle on the size segregation and burden profile during the charging process was investigated. | Jianliang Zhang Jiayong Qiu Hongwei Guo Shan Ren Hui Sun Guangwei Wang Zhengkai Gao | 2014 | Particuology2014，12，5： | 16 |
| 10 | EZH2 and STAT6 expression profiles are correlated with colorectal cancer stage and prognosis显示文摘AIM: To investigate the role of enhancer of zeste homologue 2 (EZH2) and STAT6 immunohistochemistry in the evaluation of clinical stages and prognosis of colorectal cancer (CRC). METHODS: The expression patterns were examined by immunohistochemistry in both tumor and adjacent non-neoplastic tissues of 119 CRC patients who underwent operation during the time period from 2002 to 2004. RESULTS: The positive rates of EZH2 and STAT6 in CRC cases were 69.7% (83 of 119) and 60.5% (72 of 119), respectively, and there was signifi cant differ-ence when compared with tumor adjacent non-neoplastic tissues (P < 0.05). In all CRC cases, patientswith EZH2-positive, or STAT6-positive expression had lower survival rates than those with EZH2-negative or STAT6-negative expression (P = 0.002 and P = 0.005, respectively). Co-expression of EZH2 and STAT6 showed signifi cantly higher levels in CRC cases of high clinical TNM stages (P = 0.001), and the expression of STAT6 was also correlated with lymph node metastasis and distant metastasis (P = 0.001 and P = 0.016, respectively). Multivariate analysis revealed that EZH2 expression was an independent prognostic indicator of CRC (P = 0.039). CONCLUSION: EZH2 and STAT6 expressions have significant values in distinguishing clinical stages of CRC and predicting the prognosis of the patients. | Wang, Cheng-Gang Ye, Ying-Jiang Yuan, Jing Liu, Fang-Fang Zhang, Hui Wang, Shan | 2010 | World Journal of Gastroenterology2010，16，19： | 16 |
| 11 | Influence of moisture on the growth and biomass allocation in Haloxylon ammodendron and Tamarix ramosissima seedlings in the shelterbelt along the Tarim Desert Highway, Xinjiang, China显示文摘The authors studied the effects using three different levels of irrigation on the growth and biomass allocation in H. ammodendron and T. ramosissima seedlings in the shelterbelt along the Tarim Desert Highway. The three irrigation amounts were 35 (CK), 24.5 (treatment 1), and 14 (treatment 2) kg·ind. plant-1·once-1, respectively. The results show that (1) the vertical depth of the two seedlings’ root increased with lower levels of irrigation showing that the two species adapted to decreased irrigation by root elongation in the hinterland of the Taklimakan Desert, and the vertical root depth of H. ammodendron under treatment 2 was notably higher than CK. (2) Compared with CK, the belowground biomass of treatment 1 and 2 both showed a significant increase as follows: H. ammodendron seedlings in- creased by 14.51% and 37.03% under treatment 1 and 2, respectively, while T. ramosissima seedlings increased by 68.19% and 25.78% under treatment 1 and 2, respectively. This means that H. ammoden- dron seedlings were more adapted to the conditions in treatment 2 while T. ramosissima seedlings were better adapted to treatment 1 conditions. (3) When compared with CK, the fine root bomass of these two species all exhibited some increase under both treatments, and ANOVA analysis showed that the biomass of deep layer root of the two species under treatment 2 was notably higher than CK and treatment 1. This should help seedlings to more effectively absorb soil water from deep layers during dry conditions. (4) The root-shoot ratio was different for these two species. For H. ammodendron seed- lings, the root-shoot ratio was less than 1, while for T. ramosissim seedlings it was larger than 1. The root-shoot ratio of H. ammodendron seedlings increased with decreasing levels of irrigation, and that of T. ramosissim seedlings also increased under treatment 2. (5) With decreasing levels of irrigation, due to the difference of species, the growth variation of aboveground indexes was also different, while compared with CK, it was not significant. | SHAN LiShan ZHANG XiMing WANG YouKe WANG Hui YAN HaiNong WEI Jiang XU Hao | 2008 | Chinese Science Bulletin2008，53，S2： | 15 |
| 12 | Linggui Zhugan Decoction(苓桂术甘汤)Inhibits Ventricular Remodeling after Acute Myocardial Infarction in Mice by Suppressing TGF-β1 Smad Signaling Pathway显示文摘Objective:To investigate the inhibitory effect of Linggui Zhugan Decoction(LZD,苓桂术甘汤)on the ventricular remodeling(VR)after acute myocardial infarction(AMI)and related mRNA and proteins expression in transforming growth factor-beta 1(TGF-β1)/Smad signaling pathway,and explain its putative mechanism.Methods:A VR model was generated by ligation of coronary artery in mice.Two weeks after surgery,60 mice were randomly divided into the model group,the sham-operation group(distilled water),the positive control group(2.4 mg/kg simvastatin),and the low-,medium-and high-dose LZD groups(2.1,4.2,8.4 g crude drug/kg,respectively)by a random number table,10 mice in each group.Mice in each group was treated for 4 weeks.Changes of hemodynamics indices and cardiac weight index were detected by the PowerLab data acquisition and analysis recording instrument.Morphology changes of myocardial tissue were observed by hematoxylin-eosin and Masson staining.The expressions of TGF-β1,Smad2,Smad3,p-Smad2 and p-Smad3 in myocardial tissue were detected by Western blotting.The mRNA expressions of TGF-β1,Smad2 and Smad3 were detected by reverse transcription-quantitative polymerase chain reaction(RT-qPCR).The expressions of matrix metalloprotein 2(MMP2),MMP9,collagenⅠand collagen Ⅲ were observed by immunohistochemical methods.Results:VR mice showed significant dysfunction in hemodynamic indices and cardiac structure and function.Compared with the shamoperation group,myocardial tissue damage,interstitial fibrosis occurred in the model mice,left ventricular systolic pressure(LVSP),left ventricular pressure maximum contraction rate(+dp/dtmax)and left ventricular pressure maximum relaxation rate(-dp/dtmax)decreased significantly(all P<0.01),while left ventricular end-diastolic pressure(LVEDP),cardiac weight index and left ventricular weight index elevated significantly,meanwhile TGF-β1,p-Smad2,p-Smad3,Smad2,Smad3,MMP2,MMP9,collagen Ⅰ,collagen Ⅲ protein expressions in myocardial tissue and TGF-β1 Smad2 and Smad3 mRNA expressions increased significantly(all P<0.01).Compared with the model group,LZD could significantly improve the pathological changes of myocardial tissue,increase LVSP,+dp/dtmax and-dp/dtmaxf lower LVEDP,reduce the whole heart weight index and left ventricular weight index and inhibit the over-expressions of TGF-β1f p-Smad2,p-Smad3,Smad2,Smad3,MMP2,MMP9,collagenⅠand collagenⅢproteins in myocardial tissue and mRNA expressions of TGF-β1 Smad2 and Smad3(P<0.05 or P<0.01).Conclusion:LZD can significantly suppress VR induced by AMI,and its underlying mechanism may be associated with its inhibitory effect on the TGF-β1/Smad signaling pathway. | WANG Liang SHI Hui HUANG Jin-ling XU Shan LIU Pei-pei | 2020 | Chinese Journal of Integrative Medicine2020，26，5： | 15 |
| 13 | Bacterial infection triggers and complicates acute-on-chronic liver failure in patients with hepatitis B virus-decompensated cirrhosis: A retrospective cohort study显示文摘BACKGROUND Reports on bacterial infection(BI)in decompensated cirrhosis(DC)is mainly from alcoholic cirrhosis.The role of BI as a trigger or complication of acute-onchronic liver failure(ACLF)in patients with hepatitis B virus decompensated cirrhosis(HBV-DC)remains to be investigated.AIM To investigate the impact of BI on the outcomes of the patients with HBV-DC admitted into the hospital with or without ACLF.METHODS This retrospective study included patients with HBV-DC admitted to two tertiary centers in China.In-hospital overall survival,90-d transplant-free survival,5-year post-discharge survival,and cumulative incidence of ACLF were evaluated.Risk factors for death were analyzed considering liver transplantation as a competing event.RESULTS A total of 1281 hospitalized HBV-DC patients were included;284 had ACLF at admission.The overall prevalence of BI was 28.1%.The patients with BI had a significantly lower in-hospital survival and transplant-free 90-d survival than those without,in both the patients admitted with and without ACLF.The presence of BI significantly increased the risk of developing ACLF[subdistribution hazard ratio(sHR)=2.52,95%CI:1.75-3.61,P<0.001]in the patients without ACLF.In the patients discharged alive,those who had an episode of BI had a significantly lower 5-year transplant-free survival.BI was an independent risk factor for death in the patients admitted without ACLF(sHR=3.28,95%CI:1.93-5.57),while in ACLF admissions,the presence of pneumonia,but not other type of BI,independently increased the risk of death(sHR=1.87,95%CI:1.24-2.82).CONCLUSION BI triggers ACLF in patients with HBV-DC and significantly impairs short-term survival.HBV-DC patients should be monitored carefully for the development of BI,especially pneumonia,to avoid an adverse outcome. | Zhu-Jun Cao Yu-Han Liu Chuan-Wu Zhu Shan Yin Wei-Jing Wang Wei-Liang Tang Gang-De Zhao Yu-Min Xu Lu Chen Tian-Hui Zhou Ming-Hao Cai Hui Wang Wei Cai Shi-San Bao Hai Li Qing Xie | 2020 | World Journal of Gastroenterology2020，26，6： | 15 |
| 14 | Changing Proportions of HIV-1 Subtypes and Transmitted Drug Resistance Among Newly Diagnosed HIV/AIDS Individuals—China,2015 and 2018显示文摘Introduction:With the expansion of human immunodeficiency virus(HIV)antiretroviral therapy(ART),HIV drug resistance is becoming more and more serious.This study describes the changing prevalence of HIV-1 subtypes and transmitted drug resistance(TDR)among newly diagnosed individuals in China,2015 and 2018.Methods:A total of 8,980 individuals in 2015 and 2018 from 31 provincial-level administrative divisions(PLADs)were enrolled in this study.Viral RNAs were amplified and sequenced using an in-house polymerase chain reaction(PCR)protocol.The Stanford HIV Drug Resistance Database(HIVdb)was used to predict susceptibility to 12 antiretroviral drugs.Results:The prevalence of TDR was not significantly increased over time.The prevalence of TDR was 3.8%and 4.4%in 2015 and 2018,respectively(P=0.13).The prevalence of CRF55_01B increased from 2.3%in 2015 to 3.9%in 2018(P<0.001).The drug resistance prevalence of nonnucleoside reverse transcriptase inhibitors(NNRTI)increased from 2.4%in 2015 to 3.3%in 2018(P<0.01).The prevalence of E138(P<0.001),H221(P=0.03),and V179(P<0.001)mutations increased from 0.30%,0.09%,and 0.70%in 2015 to 1.10%,0.30%,and 1.70%in 2018,respectively.Conclusions:HIV drug resistance affects the effect of antiretroviral treatment,so the monitoring of HIV TDR should be strengthened to control the transmission of HIV drug resistance. | Jingjing Hao Shan Zheng Mengze Gan Aobo Dong Ruihua Kang Miaomiao Li Shuai Zhao Jing Hu Chang Song Lingjie Liao Yi Feng Yiming Shao Yuhua Ruan Hui Xing | 2021 | China CDC weekly2021，3，53： | 13 |
| 15 | Topographic differentiations of biological soil crusts and hydraulic properties in fixed sand dunes, Tengger Desert显示文摘Biological soil crusts(BSCs) play an important role in surface soil hydrology. Soils dominated with moss BSCs may have higher infiltration rates than those dominated with cyanobacteria or algal BSCs. However, it is unnown whether improved infiltration in moss BSCs is accompanied by an increase in soil hydraulic conductivity or water retention capacity. We investigated this question in the Tengger Desert, where a 43-year-old revegetation program has promoted the formation of two distinct types of BSCs along topographic positions, i.e. the moss-dominated BSCs on the interdune land and windward slopes of the fixed sand dunes, and the algal-dominated BSCs on the crest and leeward slopes. Soil water retention capacity and hydraulic conductivity were measured using an indoor evaporation method and a field infiltration method. And the results were fitted to the van Genuchten–Mualem model. Unsaturated hydraulic conductivities under greater water pressure(<–0.01 MPa) and water retention capacities in the entire pressure head range were higher for both crust types than for bare sand. However, saturated and unsaturated hydraulic conductivities in the near-saturation range(>–0.01 MPa) showed decreasing trends from bare sand to moss crusts and to algal crusts. Our data suggested that topographic differentiation of BSCs significantly affected not only soil water retention and hydraulic conductivities, but also the overall hydrology of the fixed sand dunes at a landscape scale, as seen in the reduction and spatial variability in deep soil water storage. | Zhi Shan ZHANG Yong Le CHEN Bin Xing XU Lei HUANG Hui Juan TAN Xue Jun DONG | 2015 | Journal of Arid Land2015，7，2： | 13 |
| 16 | Seasonal and spatial distributions of phytoplankton biomass associated with monsoon and oceanic environments in the South China Sea显示文摘Seasonal variations of phytoplankton/chlorophyll-a (Chl-a) distribution, sea surface wind, sea height anomaly, sea surface temperature and other oceanic environments for long periods are analyzed in the South China Sea (SCS), especially in the two typical regions off the east coast of Vietnam and off the northwest coast of Luzon, using remote sensing data and other oceanographic data. The results show that seasonal and spatial distributions of phytoplankton biomass in the SCS are primarily influenced by the monsoon winds and oceanic environments. Off the east coast of Vietnam, Chl-a concentration is a peak in August, a jet shape extending into the interior SCS, which is associated with strong southwesterly monsoon winds, the coastal upwelling induced by offshore Ekman transport and the strong offshore current in the western SCS. In December, high Chl-a concentration appears in the upwelling region off the northwest coast of Luzon and spreads southwestward. Strong mixing by the strong northeasterly monsoon winds, the cyclonic circulation, southwestward coastal currents and river discharge have impacts on distribution of phytoplankton, so that the high phytoplankton biomass extends from the coastal areas over the northern SCS to the entire SCS in winter. These research activities could be important for revealing spatial and temporal patterns of phytoplankton and their interactions with physical environments in the SCS. | GAO Shan WANG Hui | 2008 | Acta Oceanologica Sinica2008，27，6： | 11 |
| 17 | Applying the China-PAR Risk Algorithm to Assess 10-year Atherosclerotic Cardiovascular Disease Risk in Populations Receiving Routine Physical Examinations in Eastern China显示文摘Objective To assess the 10-year Atherosclerotic Cardiovascular Disease(ASCVD) risk score among adults in eastern China using the China-PAR equation which formulated primarily for the Chinese population. Methods Data from 72,129 individuals from 35-74 years old who received routine physical examinations in eastern China were analyzed in this study. The 10-year risk scores were calculated using the China-PAR equation. The chi-square test and logistic regression were then performed to evaluate the association between the selected risk factors and overall CVD risk. Results The mean 10-year ASCVD risk scores were 3.82% ± 3.76% in men and 1.30% ± 1.65% in women based on the China-PAR equation. Overall, 20% of men and 3.5% of women were intermediate-risk, and 7.3% of men and 0.3% of women were high-risk. Waist to hip ratio(WHR) [OR = 1.16(CI 95% = 1.06-1.26)], waist to height ratio(WHtR) [OR = 1.16(CI 95% = 1.05-1.28)], non-high-density lipoprotein cholesterol(non-HDL-C) [OR = 1.23(CI 95% = 1.09-1.39)], and total cholesterol(TC)/HDL-C [OR = 1.68(CI 95% = 1.46-1.94)] were more strongly associated with CVD risk than body-mass index(BMI), waist circumference(WC), and TC alone. Conclusion Male-specific prevention and treatment strategies for ASCVD are needed in eastern China. In addition, WHR, WHtR, non-HDL-C, and TC/HDL-C which not included in the the China-PAR equation were also independently associated with 10-year ASCVD risk score categories. | LI Hui Hua HUANG Shan LIU Xing Zhen ZOU Da Jin | 2019 | Biomedical and Environmental Sciences2019，32，2： | 9 |

| 19 | Cross electro-nape-acupuncture ameliorates cerebral hemorrhageinduced brain damage by inhibiting necroptosis显示文摘BACKGROUND Receptor interacting protein kinase 1(RIPK1)-mediated cell death,including apoptosis and necroptosis,belongs to programmed cell death.It has been reported that RIPK1-mediated necroptosis exists in lesions of cerebral hemorrhage(CH).Electroacupuncture,a treatment derived from traditional Chinese medicine,could improve neurological impairment in patients with brain injury.AIM To investigate the protective role of cross electro-nape acupuncture(CENA)in CH,and clarify the potential mechanism.METHODS CH rat models were established,and CENA was applied to the experimental rats.Neurological functions and encephaledema were then measured.Necrotic cells in the brain of rats with CH were evaluated by propidium iodide staining.Necroptosis was assessed by immunofluorescence.Activation of the necroptosisrelated pathway was detected by western blot.Extraction of brain tissue,cerebrospinal fluid and serum samples was conducted to measure the expression and secretion of inflammatory cytokines by quantitative real-time polymerase chain reaction and enzyme-linked immunosorbent assay.RESULTS The necroptotic marker p-MLKL was detectable in the brains of rats with CH.Next,we found that CENA could ameliorate neurological functions in rat models of CH.Moreover,the upregulation of RIPK1-mediated necroptosis-related molecules in the brains of rats with CH were inhibited by CENA.Further investigation revealed that CENA partially blocked the interaction between RIPK1 and RIPK3.Finally,in vivo assays showed that CENA decreased the expression of the inflammatory cytokines tumor necrosis factor-α,interleukin-6 and interleukin-8 in CH rat models.CONCLUSION These findings revealed that CENA exerts a protective role in CH models by inhibiting RIPK1-mediated necroptosis. | Guo-Feng Cai Zhong-Ren Sun Zhe Zhuang Hai-Chun Zhou Shan Gao Kai Liu Li-Li Shang Kun-Ping Jia Xiu-Zhen Wang Hui Zhao Guo-Liang Cai Wen-Li Song Sheng-Nan Xu | 2020 | World Journal of Clinical Cases2020，8，10： | 9 |
| 20 | Celastrol targets adenylyl cyclase-associated protein 1 to reduce macrophages-mediated inflammation and ameliorates high fat diet-induced metabolic syndrome in mice显示文摘Metabolic syndrome is a clustering of metabolic disorder with unclear molecular mechanism.Increasing studies have found that the pathogenesis and progression of metabolic syndrome are closely related to inflammation.Here,we report celastrol,a traditional Chinese medicine,can improve high fat diet-induced metabolic syndrome through suppressing resistin-induced inflammation.Mechanistically,celastrol binds to adenylyl cyclase associated protein 1(CAP1)and inhibits the interaction between CAP1 and resistin,which restrains the cyclic adenylate monophosphate(cAMP)-protein kinase A(PKA)-nuclear factor kappa-B(NF-kB)signaling pathway and ameliorates high fat diet-induced murine metabolic syndrome.Knockdown of CAP1 in macrophages abrogated the resistin-mediated inflammatory activity.In contrast,overexpression of CAP1 in macrophages aggravated inflammation.Taken together,our study identifies celastrol,which directly targets CAP1 in macrophages,might be a promising drug candidate for the treatment of inflammatory metabolic diseases,such as metabolic syndrome. | Yuyu Zhu Ning Wan Xinni Shan Guoliang Deng Qiang Xu Hui Ye Yang Sun | 2021 | Acta Pharmaceutica Sinica B2021，11，5： | 9 |
