1Towards 6G wireless communication networks:vision,enabling technologies,and new paradigm shifts显示文摘The fifth generation(5G)wireless communication networks are being deployed worldwide from 2020 and more capabilities are in the process of being standardized,such as mass connectivity,ultra-reliability,and guaranteed low latency.However,5G will not meet all requirements of the future in 2030 and beyond,and sixth generation(6G)wireless communication networks are expected to provide global coverage,enhanced spectral/energy/cost efficiency,better intelligence level and security,etc.To meet these requirements,6G networks will rely on new enabling technologies,i.e.,air interface and transmission technologies and novel network architecture,such as waveform design,multiple access,channel coding schemes,multi-antenna technologies,network slicing,cell-free architecture,and cloud/fog/edge computing.Our vision on 6G is that it will have four new paradigm shifts.First,to satisfy the requirement of global coverage,6G will not be limited to terrestrial communication networks,which will need to be complemented with non-terrestrial networks such as satellite and unmanned aerial vehicle(UAV)communication networks,thus achieving a space-airground-sea integrated communication network.Second,all spectra will be fully explored to further increase data rates and connection density,including the sub-6GHz,millimeter wave(mmWave),terahertz(THz),and optical frequency bands.Third,facing the big datasets generated by the use of extremely heterogeneous networks,diverse communication scenarios,large numbers of antennas,wide bandwidths,and new service requirements,6G networks will enable a new range of smart applications with the aid of artificial intelligence(AI)and big data technologies.Fourth,network security will have to be strengthened when developing 6G networks.This article provides a comprehensive survey of recent advances and future trends in these four aspects.Clearly,6G with additional technical requirements beyond those of 5G will enable faster and further communications to the extent that the boundary between physical and cyber worlds disappears.Xiaohu YOU Cheng-Xiang WANG Jie HUANG Xiqi GAO Zaichen ZHANG Mao WANG Yongming HUANG Chuan ZHANG Yanxiang JIANG Jiaheng WANG Min ZHU Bin SHENG Dongming WANG Zhiwen PAN Pengcheng ZHU Yang YANG Zening LIU Ping ZHANG Xiaofeng TAO Shaoqian LI Zhi CHEN Xinying MA Chih-Lin I Shuangfeng HAN Ke LI Chengkang PAN Zhimin ZHENG Lajos HANZO Xuemin(Sherman)SHEN Yingjie Jay GUO Zhiguo DING Harald HAAS Wen TONG Peiying ZHU Ganghua YANG Jun WANG Erik GLARSSON Hien Quoc NGO Wei HONG Haiming WANG Debin HOU Jixin CHEN Zhe CHEN Zhangcheng HAO Geoffrey Ye LI Rahim TAFAZOLLI Yue GAO HVincent POOR Gerhard P.FETTWEIS Ying-Chang LIANG 2021Science China(Information Sciences)2021,64,1:122

4Pioglitazone attenuates the severity of sodium taurocholate-induced severe acute pancreatitis显示文摘AIM: To determine the effect of pioglitazone, a specific peroxisome proliferator-activated receptor-γ (PPARγ) ligand, on development of severe acute pancreatitis (SAP) and expression of nuclear factor-kappa B (NF-κB) and intercellular adhesion molecule-1 (ICAM-1) in the pancreas. METHODS: Male Sprague-Dawley (SD) rats (160-200 g) were randomly allocated into three groups (n = 18 in each group): severe acute pancreatitis group, pioglitazone group, sham group. SAP was induced by retrograde infusion of 1 mL/kg body weight 5% sodium taurocholate (STC) into the biliopancreatic duct of male SD rats. Pioglitazone was injected intraperitoneally two hours piror to STC infusion. Blood and ascites were obtained for detecting amylase and ascitic capacity. Pancreatic wet/dry weight ratio, expression of NF-κB and ICAM-1 in pancreatic tissues were detected by immunohistochemical staining. Pancreatic tissue samples were stained with hematoxylin and eosin (HE) for routine optic microscopy. RESULTS: Sham group displayed normal pancreatic structure. SAP group showed diffuse hemorrhage, necrosis and severe edema in focal areas of pancreas. There was obvious adipo-saponification in abdominal cavity. Characteristics such as pancreatic hemorrhage, necrosis, severe edema and adipo-saponification were found in pioglitazone group, but the levels of those injuries were lower in pioglitazone group than those in SAP group. The wet/dry pancreatic weight ratio, ascetic capacity, serum and ascitic activities of anylasein the SAP group were significantly higher than those in the sham group and pioglitazone group respectively (6969.50 ± 1368.99 vs 2104.67 ± 377.16, 3.99 ± 1.22 vs 2.48 ± 0.74, P < 0.01 or P < 0.05). According to Kusske criteria, the pancreatic histologic score showed that interstitial edema, inflammatory infiltration, parenchyma necrosis and parenchyma hommorrhage in SAP group significantly differed from those in the sham group and pioglitazone group (7.17 ± 1.83 vs 0.50 ± 0.55, 7.67 ± 0.82 vs 6.83 ± 0.75, P < 0.01, P < 0.05. The expression of NF-κB and ICAM-1 in sham group was lower than that in SAP group and pioglitazone group (0.50 ± 0.55 vs 33 ± 1.21, P < 0.01). There was a significant difference in the expression of NF-κB and ICAM-1 between SAP group and pioglitazone group (7.50 ± 1.05 vs 11.33 ± 1.75, 0.80 ± 0.53 vs 1.36 ± 0.54, P < 0.01 or P < 0.05) at 12 h after the induction of pancreatitis. CONCLUSION: Pioglitazone attenuates the severity of SAP. The beneficial effect of pioglitazone is multifactorial due to its anti-inflammatory activities, most likely through the inhibition of ICAM-1 expression and NF-κB activation. Specific ligands of PPARγ may represent the novel and effective means of clinical therapy for SAP.Ping Xu Xiao-Jiang Zhou Ling-Quan Chen Jiang Chen Yong Xie Long-HuaLv Xiao-Hua Hou 2007World Journal of Gastroenterology2007,13,13:20
5Efficacy and safety of Shexiang Baoxin pill(MUSKARDIA)in patients with stable coronary artery disease:a multicenter,double-blind,placebo-controlled phase IV randomized clinical trial显示文摘Background:The Shexiang Baoxin Pill(MUSKARDIA)has been used for treating coronary artery disease(CAD)and angina for more than 30 years in China.Nevertheless,methodologically sound trials on the use of MUSKARDIA in CAD patients are scarce.The aim of the study is to determine the effects of MUSKARDIA as an add-on to optimal medical therapy(OMT)in patients with stable CAD.Methods:A total of 2674 participants with stable CAD from 97 hospitals in China were randomized 1:1 to a MUSKARDIA or placebo group for 24 months.Both groups received OMT according to local tertiary hospital protocols.The primary outcome was the occurrence of a major adverse cardiovascular event(MACE),defined as a composite of cardiovascular death,non-fatal myocardial infarction(MI),or non-fatal stroke.Secondary outcomes included all-cause mortality,non-fatal MI,non-fatal stroke,hospitalization for unstable angina or heart failure,peripheral revascularization,angina stability and angina frequency.Results:In all,99.7%of the patients were treated with aspirin and 93.0%with statin.After 2 years of treatment,the occurrence of MACEs was reduced by 26.9%in the MUSKARDIA group(MUSKARDIA:1.9%vs.placebo:2.6%;odds ratio=0.80;95%confidence interval:0.45-1.07;P=0.2869).Angina frequency was significantly reduced in the MUSKARDIA group at 18 months(P=0.0362).Other secondary endpoints were similar between the two groups.The rates of adverse events were also similar between the two groups(MUSKARDIA:17.7%vs.placebo:17.4%,P=0.8785).Conclusions:As an add-on to OMT,MUSKARDIA is safe and significantly reduces angina frequency in patients with stable CAD.Moreover,the use of MUSKARDIA is associated with a trend toward reduced MACEs in patients with stable CAD.The results suggest that MUSKARDIA can be used to manage patients with CAD.Trial registration:chictr.org.cn,No.ChiCTR-TRC-12003513.Jun-Bo Ge Wei-Hu Fan Jing-Min Zhou Hai-Ming Shi Fu-Sui Ji Yang Wu Yu-Lan Zhao Jun Qian Yuan-Zhe Jin Ying-Wu Liu Sheng-Huang Wang Sheng-Hu He Ping Yang Jie Wu Feng Lu Zi-Shan Hou 2021Chinese Medical Journal2021,,2:17
6Liver Enzymes Concentrations Are Closely Related to Pre-diabetes:Findings of the Shanghai Diabetes Study Ⅱ (SHDS Ⅱ)显示文摘Objective To investigate the relationship of liver enzymes with hyperglycemia in a large population in Shanghai and identify the association between liver enzymes and insulin resistance.Methods A total of 3 756 participants were enrolled.Each participant underwent an oral glucose tolerance test and completed a questionnaire.Anthropometric indices were recorded and serum samples were collected for measurement.Results Liver enzymes concentrations were independently associated with i-IGT,IFG+IGT,and diabetes.With the increase of ALT and GGT concentrations,ORs for i-IGT,IFG+IGT,and diabetes increased gradually.By comparing patients in the highest quartile of GGT concentrations or ALT concentrations with those in the lowest quartile (Q1),ORs for i-IGT,IFG+IGT,or diabetes was significant after adjustment.Both ALT and GGT concentrations were linearly correlated with HOMA-IR and independently associated with HOMA-IR [ALT OR (95% CI):2.56 (1.51-4.34) P=0.00;GGT OR (95% CI):2.66 (1.53-4.65) P=0.00].Conclusion Serum ALT and GGT concentrations were closely related to pre-diabetes and diabetes in the Shanghai population and positively associated with insulin resistance.GAO Fei PAN Jie Min HOU Xu Hong FANG Qi Chen LU Hui Juan TANG Jun Ling GU Hui Lin PAN Zhi Jian YAO You Hua SHEN Wei Zhen JIA Wei Ping 2012Biomedical and Environmental Sciences2012,25,1:15
7Responses of the Toll-like receptor and melanoma differentiation-associated protein 5 signaling pathways to avian infectious bronchitis virus infection in chicks显示文摘Avian infectious bronchitis virus(IBV) is a Gammacoronavirus in the family Coronaviridae and causes highly contagious respiratory disease in chickens. Innate immunity plays significant roles in host defense against IBV. Here, we explored the interaction between IBV and the host innate immune system. Severe histopathological lesions were observed in the tracheal mucosa at 3–5days post inoculation(dpi) and in the kidney at 8 dpi, with heavy viral loads at 1–11 and 1–28 dpi,respectively. The expression of m RNAs encoding Toll-like receptor(TLR) 3 and TLR7 were upregulated at 3–8 dpi, and that of TIR-domain-containing adapter-inducing interferon(IFN) β(TRIF) was upregulated at 21 dpi in the trachea and kidney. Myeloid differentiation primary response protein 88(My D88) was upregulated in the trachea during early infection. Tumor necrosis factor receptor-associated factor(TRAF) 3 and TRAF6 were upregulated expression in both tissues.Moreover, melanoma differentiation-associated protein 5(MDA5), laboratory of genetics and physiology 2(LGP2), stimulator of IFN genes(STING), and mitochondrial antiviral signaling protein(MAVS), as well as TANK binding kinase 1(TBK1), inhibitor of kappa B kinase(IKK) ?, IKKα, IKKβ,IFN regulatory factor(IRF) 7, nuclear factor of kappa B(NF-κB), IFN-α, IFN-β, various interleukins(ILs), and macrophage inflammatory protein-1β(MIP-1β) were significantly upregulated in the trachea and downregulated in the kidney. These results suggested that the TLR and MDA5 signaling pathways and innate immune cytokine were induced after IBV infection. Additionally,consistent responses to IBV infection were observed during early infection, with differential and complicated responses in the kidney.Yining He Zhiwen Xie Jinglong Dai Yanjie Cao Jinlian Hou Yansheng Zheng Tianchao Wei Meilan Mo Ping Wei 2016Virologica Sinica2016,31,1:14

9Effect of acupuncture at Neiguan (PC 6) on cardiac function using echocardiography in myocardial ischemia rats induced by isoproterenol显示文摘OBJECTIVE: To investigate the effect of acupuncture at Neiguan(PC 6) on cardiac function using echocardiography in rat models of myocardial ischemia(MI) induced by isoproterenol(ISO).METHODS: Twenty-seven Sprague-Dawley rats were randomly assigned to normal, model, and acupuncture groups. The model and acupuncture groups were given injections of ISO(85 mg/kg) to establish the MI model. After model establishment,the acupuncture group was treated with acupuncture at Neiguan(PC 6) for 30 min. Echocardiography was used to monitor diastolic and systolic function for 30 min starting from the time after the acupuncture needles were removed. Changes in the length of left ventricular internal diameter at end-diastole(LVIDd), length of left ventricular internal diameter at end-systole(LVIDs), the ratio of mitral peak velocity at early diastole and atrial contraction(E/A), ejection fraction(EF), fractional shortening(FS), and stroke volume(SV) were measured.RESULTS: Compared with the model group at 0and 15 min after needles were removed, the means of LVIDd and LVIDs were significantly lower(P <0.01) and E/A, EF, FS, and SV significantly higher(P < 0.01) in the acupuncture group. In the acupuncture group, the means of LVIDd and LVIDs15 min after the needles were removed were significantly higher(P < 0.01) than those at 0 min. The means of E/A, EF, FS, and SV significantly decreased(P < 0.01) from 0 to 15 min in the acupuncture group.CONCLUSION: These findings indicate that acupuncture at Neiguan(PC 6) can affect cardiac function by increasing left ventricular diastolic and systolic function in MI rat models, but the effect only lasts for 15 min.Wang Songzi Ren Lu Jia Lianqun Gu Zhongyue Fan Xu Chen Wenna Hou Ping Liang Fanrong Rong Peijing Ma Tieming Liu Xulai Chen Yiguo 2015Journal of Traditional Chinese Medicine2015,35,6:12
10Association between Chinese Medicine Therapy and Survival Outcomes in Postoperative Patients with NSCLC: A Multicenter, Prospective, Cohort Study显示文摘Objective:To evaluate the association between Chinese medicine(CM)therapy and disease-free survival(DFS)outcomes in postoperative patients with non-small cell lung cancer(NSCLC).Methods:This multiple-center prospective cohort study was conducted in 13 medical centers in China.Patients with stage I,II,or IDA NSCLC who had undergone radical resection and received conventional postoperative treatment according to the National Comprehensive Cancer Network(NCCN)guidelines were recruited.The recruited patients were divided into a CM treatment group and a control group according to their wishes.Patients in the CM treatment group received continuous CM therapy for more than 6 months or until disease progression.Patients in the control group received CM therapy for less than 1 month.Follow-up was 8nducted over 3 years.The primary outcome was DFS,with recurrence/metastasis rates as a secondary outcome.Results:Between May 2013 and August 2016,503 patients were enrolled into the cohort;266 were classified in the CM treatment group and 237 in the control group.Adjusting for covariates,high exposure to CM was associated with better DFS[hazard ratio(HR)=0.417,95%confidential interval(Cl):0.307-0.567)].A longer duration of CM therapy(6-12 months,12-18 months,>24 months)was associated with lower recurrence and metastasis rates(HR=0.225,0.119 and 0.083,respectively).In a subgroup exploratory analysis,CM therapy was also a protective factor of cancer recurrence and metastasis in both stage n-MA(HR=0.50,95%Cl:0.37-0.67)and stage IDA NSCLC postoperative patients(HR=0.48,95%Cl:0.33-0.71),DFS was even longer among CM treatment group patients.Conclusions:Lon ger duration of CM therapy could be 8nsidered a protective factor of cancer recurrence and metastasis.CM treatment is associated with improving survival outcomes of postoperative NSCLC patients in China.WANG Xue-qian ZHANG Ying HOU Wei WANG Ying-tian ZHENG Jia-bin LI Jie LIN Li-zhu JIANG Yi-lan WANG Shen-yu XIE Ying ZHANG Hong-liang SHU Qi-jin LI Ping WANG Wei YOU Jian-liang LI Ge LIU Jie FAN Hui-ting ZHANG Mei-ying LIN Hong-sheng 2019Chinese Journal of Integrative Medicine2019,25,11:12
11The Effects of Demographic Features on Differences in Sensitivity between PCL-C and SCL-90 Scores in a Follow-up Study in Secondary School Students in the Wenchuan Earthquake Region显示文摘Objective To analyze the sensitivity of effect factors between the PCL‐C and the SCL‐90,to provide evidence for social psychological crisis screening and post‐trauma interventions.Methods We administered the PCL‐C and SCL‐90 to screen for PTSD and other psychological problems among students who survived the disaster and continued their school studies.The surveys were carried out 3,6,9,and 12 months after the earthquake.A bivariate 2‐level logistic model was used to explore the different levels of sensitivity among students.The factors influencing the relationships between PTSD and depression,and between PTSD and anxiety were examined.Results We analyzed data from 1 677 students,revealing that female students in higher grades were more likely to exhibit symptoms of depression,rather than PTSD,compared with the control group (males in lower grades),and the difference was significant (P<0.05).In contrast,ethnic minorities were more likely to exhibit PTSD symptoms compared to the others.In addition,female students were more likely to exhibit symptoms of anxiety than PTSD.Other effects that did not reach statistical significance were suggested to have a similar influence on PTSD,depression,and anxiety.Conclusion After a natural disaster,specific aspects of depression and anxiety should be examined,avoiding an overemphasis on PTSD in social psychological crisis interventions.HOU Feng Su LI Ting LI Juan HU Xiao Qin LIU Zhi Yue YUAN Ping 2011Biomedical and Environmental Sciences2011,24,6:11
12Mechanisms of Huangqi Decoction Granules (黄芪汤颗粒剂) on Hepatitis B Cirrhosis Patients Based on RNA-Sequencing显示文摘Objective: To explore the action mechanisms of Huangqi Decoction Granules(黄芪汤颗粒剂, HQDG) on hepatitis B cirrhosis. Methods: A total of 85 patients with hepatitis B cirrhosis were randomly divided into HQDG group(42 cases) and control group(43 cases) by a random number table and were treated with HQDG or placebo for 48 weeks(6 g per times and orally for 3 times a day), respectively. After RNA-sequencing of serum samples extracted from the patients, the differentially expressed genes(DEGs) in HQDG and control groups before and after treatment were separately screened. The DEGs were then performed pathway enrichment analysis and proteinprotein interaction(PPI) network analysis. The expression levels of key genes were detected by quantitative realtime polymerase chain reaction(qRT-PCR). Results: After the investigation, 4 and 3 cases were respectively excluded from HQD and control groups because of the incomplete data. Additionally, 3 and 5 cases were lost to follow up in HQD and control groups, respectively. Finally, a total of 70 cases with good compliance were included for further DEGs analysis. A total of 1,070 DEGs(including 455 up-regulated genes and 615 down-regulated genes) in HQDG group and 227 DEGs(including 164 up-regulated genes and 63 down-regulated genes) in the control group were identified after treatment. Compared with the control group, 1,043 DEGs were specific in HQDG group. Besides, 1 up-regulated transcription factor(TF, such as GLI family zinc finger 1, GLI1) and 25 down-regulated TFs(such as drosophila mothers against decapentaplegic proteinfamily member 2, SMAD2) were identified. Pathway enrichment analysis showed that down-regulated Ras homolog gene family member A(RHOA) was enriched in pathogenic Escherichia coli infection. In the PPI network, up-regulated epidermal growth factor receptor(EGFR), and down-regulated cell division cycle 42(CDC42) as well as v-akt murine thymoma viral oncogene homolog 1(AKT1) had higher degrees. Moreover, long non-coding RNAs(lncR NA) growth arrest-specific 5(GAS5) was involved in the lncR NA-target regulatory network. Furthermore, qR T-PCR revealed that expression levels of CDC42 and GLI1 had significant differences in HQDG group before and after treatment(P<0.05). Conclusions: CDC42 and GLI1 may be the targets of HQDG in patients with hepatitis B cirrhosis. Additionally, SMAD2, EGFR, AKT1, RHOA and GAS5 might be associated with the curative effect of HQDG on hepatitis B cirrhosis patients.CHENG Yang LIU Ping HOU Tian-lu Maerbiya Maimaitisidike Reyangguli Ababaikeli Aini Abudureyimu 2019Chinese Journal of Integrative Medicine2019,25,7:10
13Lymphocyte-to-monocyte ratio effectively predicts survival outcome of patients with obstructive colorectal cancer显示文摘BACKGROUND Obstructive colorectal cancer(OCC)is always accompanied by severe complications,and the optimal strategy for patients with OCC remains undetermined.Different from emergency surgery(ES),self-expandable metal stents(SEMS)as a bridge to surgery(BTS),could increase the likelihood of primary anastomosis.However,the stent failure and related complications might give rise to a high recurrence rate.Few studies have focused on the indications for either method,and the relationship between preoperative inflammation indexes and the prognosis of OCC is still underestimated.AIM To explore the indications for ES and BTS in OCCs based on preoperative inflammation indexes.METHODS One hundred and twenty-eight patients who underwent ES or BTS from 2008 to 2015 were enrolled.Receiver operating characteristic(ROC)curve analysis was used to define the optimal preoperative inflammation index and its cutoff point.Kaplan–Meier analyses and Cox proportional hazards models were applied to assess the association between the preoperative inflammation indexes and the survival outcomes[overall survival(OS)and disease-free survival(DFS)].Stratification analysis was performed to identify the subgroups that would benefit from ES or BTS.RESULTS OS and DFS were comparable between the ES and BTS groups(P>0.05).ROC curve analysis showed derived neutrophil-to-lymphocyte ratio(dNLR)as the optimal biomarker for the prediction of DFS in ES(P<0.05).Lymphocyte-tomonocyte ratio(LMR)was recommended for BTS with regard to OS and DFS(P<0.05).dNLR was related to stoma construction(P=0.001),pneumonia(P=0.054),and DFS(P=0.009)in ES.LMR was closely related to lymph node invasion(LVI)(P=0.009),OS(P=0.020),and DFS(P=0.046)in the BTS group.dNLR was an independent risk factor for ES in both OS(P=0.032)and DFS(P=0.016).LMR affected OS(P=0.053)and DFS(P=0.052)in the BTS group.LMR could differentiate the OS between the ES and BTS groups(P<0.05).CONCLUSION Preoperative dNLR and LMR could predict OS and DFS in patients undergoing ES and BTS,respectively.For OCC,as the potential benefit group,patients with a low LMR might be preferred for BTS via SEMS insertion.Xian-Qiang Chen Chao-Rong Xue Ping Hou Bing-Qiang Lin Jun-Rong Zhang 2019World Journal of Gastroenterology2019,25,33:10

15Hypoglycemic activity of puerarin through modulation of oxidative stress and mitochondrial function via AMPK显示文摘Hyperglycemia is the dominant phenotype of diabetes and the main contributor of diabetic complications. Puerarin is widely used in cardiovascular diseases and diabetic vascular complications. However, little is known about its direct effects on diabetes. The aim of our study is to investigate its antidiabetic effect in vivo and in vitro, and explore the underlying mechanism. We used type I diabetic mice induced by streptozotocin to observe the effects of puerarin on glucose metabolism. In addition, oxidative stress and hepatic mitochondrial respiratory activity were evaluated in type I diabetic mice. In vitro, glucose consumption in Hep G2 cells was assayed along with the q PCR detection of glucogenesis genes expression. Moreover, ATP production was examined and phosphorylation of AMPK was determined using Western blot. Finally, the molecular docking was performed to predict the potential interaction of puerarin with AMPK utilizing program Lib Dock of Discovery Studio 2018 software. The results showed that puerarin improved Hep G2 glucose consumption and upregulated the glucogenesis related genes expression. Also, puerarin lowered fasting and fed blood glucose with improvement of glucose tolerance in type I diabetic mice. Further mechanism investigation showed that puerarin suppressed oxidative stress and improved hepatic mitochondrial respiratory function with enhancing ATP production and activating phosphorylation of AMPK. Docking study showed that puerarin interacted with AMPK activate site and enhancing phosphorylation. Taken together, these findings indicated that puerarin exhibited the hypoglycemic effect through attenuating oxidative stress and improving mitochondrial function via AMPK regulation, which may serve as a potential therapeutic option for diabetes treatment.HOU Bi-Yu ZHAO Yue Rong MA Peng XU Chun-Yang HE Ping YANG Xiu-Ying ZHANG Li QIANG Gui-Fen DU Guan-Hua 2020Chinese Journal of Natural Medicines2020,18,11:9

17Comparison of microwave-assisted extraction of aloe-emodin in aloe with Soxhlet extraction and ultrasound-assisted extraction显示文摘This paper reports the extraction of aloe-emodin from aloe by microwave-assisted extraction.The effects of various factors,including the solvent,the ratio (mL/g) of the solvent to the sample,microwave irradiation time and microwave power,were discussed in the experiments.The yield of aloe-emodin was determined by HPLC.The optimized conditions for microwave-assisted extraction of aloe-emodin were concluded as follows: the solvent is 80% ethanol (V/V) solution,microwave irradiation time is 3 min and microwave power is 340 W.Additionally,HPLC fingerprint was developed for consistency evaluation of aloe.The similarities of 3 aloe samples obtained by microwave-assisted extraction,ultrasound-assisted extraction and Soxhlet extraction were more than 0.9,indicating that 3 aloe samples were consistent.Compared with Soxhlet extraction and ultrasound-assisted extraction,microwave extraction is a rapid method with higher yield and less solvent consumption.Aloe samples treated by microwave-assisted extraction,ultrasound-assisted extraction and Soxhlet extraction were observed using transmission electronic microscopy.The micrographs provide evidence of more breakage of chloroplasts treated by microwave-assisted extraction as compared to Soxhlet extraction and ultrasound-assisted extraction.WANG GuiHua SU Ping ZHANG Fan HOU XiangYan YANG Yi GUO ZhenKu 2011Science China Chemistry2011,54,1:8
18Simultaneous Detection of 13 Key Bacterial Respiratory Pathogens by Combination of Multiplex PCR and Capillary Electrophoresis显示文摘Objective Lower respiratory tract infections continue to pose a significant threat to human health. It is important to accurately and rapidly detect respiratory bacteria. To compensate for the limits of current respiratory bacteria detection methods, we developed a combination of multiplex polymerase chain reaction(PCR) and capillary electrophoresis(MPCE) assay to detect thirteen bacterial pathogens responsible for lower respiratory tract infections, including Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, Staphylococcus aureus, Mycoplasma pneumoniae, Legionella spp., Bordetella pertussis, Mycobacterium tuberculosis complex, Corynebacterium diphtheriae, and Streptococcus pyogenes. Methods Three multiplex PCR reactions were built, and the products were analyzed by capillary electrophoresis using the high-throughput DNA analyzer. The specificity of the MPCE assay was examined and the detection limit was evaluated using DNA samples from each bacterial strain and the simulative samples of each strain. This assay was further evaluated using 152 clinical specimens and compared with real-time PCR reactions. For this assay, three nested-multiplex-PCRs were used to detect these clinical specimens. Results The detection limits of the MPCE assay for the 13 pathogens were very low and ranged from 10^(-7) to 10^(-2) ng/μL. Furthermore, analysis of the 152 clinical specimens yielded a specificity ranging from 96.5%-100.0%, and a sensitivity of 100.0% for the 13 pathogens. Conclusion This study revealed that the MPCE assay is a rapid, reliable, and high-throughput method with high specificity and sensitivity. This assay has great potential in the molecular epidemiological survey of respiratory pathogens.JIANG Lu Xi REN Hong Yu ZHOU Hai Jian ZHAO Si Hong HOU Bo Yan YAN Jian Ping QIN Tian CHEN Yu 2017Biomedical and Environmental Sciences2017,30,8:8
19Association of Overlapped and Un-overlapped Comorbidities with COVID-19 Severity and Treatment Outcomes: A Retrospective Cohort Study from Nine Provinces in China显示文摘Objective Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.Methods A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of COVID-19.Results Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two weeks.Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.MA Yan ZHU Dong Shan CHEN Ren Bo SHI Nan Nan LIU Si Hong FAN Yi Pin WU Gui Hui YANG Pu Ye BAI Jiang Feng CHEN Hong CHEN Li Ying FENG Qiao GUO Tuan Mao HOU Yong HU Gui Fen HU Xiao Mei HU Yun Hong HUANG Jin HUANG Qiu Hua HUANG Shao Zhen JI Liang JIN Hai Hao LEI Xiao LI Chun Yan LI Min Qing LI Qun Tang LI Xian Yong LIU Hong De LIU Jin Ping LIU Zhang MA Yu Ting MAO Ya MO Liu Fen NA Hui WANG Jing Wei SONG Fang Li SUN Sheng WANG Dong Ting WANG Ming Xuan WANG Xiao Yan WANG Yin Zhen WANG Yu Dong WU Wei WU Lan Ping XIAO Yan Hua XIE Hai Jun XU Hong Ming XU Shou Fang XUE Rui Xia YANG Chun YANG Kai Jun YUAN Sheng Li ZHANG Gong Qi ZHANG Jin Bo ZHANG Lin Song ZHAO Shu Sen ZHAO Wan Ying ZHENG Kai ZHOU Ying Chun ZHU Jun Teng ZHU Tian Qing ZHANG Hua Min WANG Yan Ping WANG Yong Yan 2020Biomedical and Environmental Sciences2020,33,12:8
20SDN Based Next Generation Mobile Network With Service Slicing and Trials显示文摘Software-Defined Network(SDN)empowers the evolution of Internet with the OpenFlow,Network Virtualization and Service Slicing strategies.With the fast increasing requirements of Mobile Internet services,the Internet and Mobile Networks go to the convergence.Mobile Networks can also get benefits from the SDN evolution to fulfill the Sth Generation(5G) capacity booming.The article implements SDN into Frameless Network Architecture(FNA) for5G Mobile Network evolution with proposed Mobile-oriented OpenFlow Protocol(MOFP).The Control Plane/User Plane(CP/UP)separation and adaptation strategy is proposed to support the User-Centric scenario in FNA.The traditional Base Station is separated with Central Processing Entity(CPE) and Antenna Element(AE) to perform the OpenFlow and Network Virtualization.The AEs are released as new resources for serving users.The mobile-oriented Service Slicing with different Quality of Service(QoS) classification is proposed and Resource Pooling based Virtualized Radio Resource Management(VRRM) is optimized for the Service Slicing strategy with resource-limited feature in Mobile Networks.The capacity gains are provided to show the merits of SDN based FNA.And the MiniNet based Trial Network with Service Slicing is implemented with experimental results.XU Xiaodong ZHANG Huixin DAI Xun HOU Yanzhao TAO Xiaofeng ZHANG Ping 2014China Communications2014,11,2:7
