| 1 | PREVALENCE AND RISK FACTORS OF PERIPHERAL ARTERIAL DISEASE IN DIABETIC PATIENTS OVER 50 YEARS OLD IN CHINA显示文摘Objective To investigate the prevalence of peripheral arterial disease (PAD) in China type 2 diabetic patients and to demonstrate the relationships between putative risk factors and PAD. Methods In total 1 397 type 2 diabetic patients aged 50 years and older were enrolled and determined ankle-brachial index (ABI) and brachial-ankle pulse wave velocity (baPWV) in 15 Class III Grade A hospitals in 7 major cities of China. Results Mean patient age was 63.7±8.2 years and mean duration of diabetes mellitus was 9.39±7.4 years. Two hundreds and seventy-two (19.47%) patients were diagnosed as PAD by ABI <0.9, 122 (18.37%) in male and 150 (20.46%) in female. PAD patients had a significantly longer duration of diabetes mellitus, higher hemoglobin Alc, and a significantly lower mean body mass index than non-PAD ones. Aging, smoking, and systolic blood pressure were found to be positively related with the prevalence of PAD. In terms of lipid profiles, no variable was found to relate with PAD. Notably, baPWV showed as the same significant guiding index for PAD, almost matched with ABI. Conclusions PAD is a common complication in China type 2 diabetic patients. Therefore, PAD screening and treatment should be emphasized for diabetic patients with high risk factors. | Heng Guan Yong-jun Li Zhang-rong XU Guang-wei Li Xiao-hui Guo Zhi-min Liu Da-jin Zou Hui-li Xing Wei Liu Zheng-yan Sheng Hao-ming Tian Da-long Zhu De-min YU Wei-te Zhuang Lu-lu Chen Jian-ping Weng | 2007 | Chinese Medical Sciences Journal2007，22，2： | 41 |
| 2 | Systematic review of the outcomes of surgical resection for intermediate and advanced Barcelona Clinic Liver Cancer stage hepatocellular carcinoma:A critical appraisal of the evidence显示文摘AIM To perform a systematic review to determine the survival outcomes after curative resection of intermediate and advanced hepatocellular carcinomas(HCC).METHODS A systematic review of the published literature was performed using the PubM ed database from 1 st January 1999 to 31 st Dec 2014 to identify studies that reported outcomes of liver resection as the primary curative treatment for Barcelona Clinic Liver Cancer(BCLC) stage B or C HCC. The primary end point was to determine the overall survival(OS) and disease free survival(DFS) of liver resection of HCC in BCLC stage B or C in patients with adequate liver reserve(i.e., Child's A or B status). The secondary end points were to assess the morbidity and mortality of liver resection in large HCC(defined as lesions larger than 10 cm in diameter) and to compare the OS and DFS after surgical resection of solitary vs multifocal HCC.RESULTS We identified 74 articles which met the inclusion criteria and were analyzed in this systematic review. Analysis of the resection outcomes of the included studies were grouped according to(1) BCLC stage B or C HCC,(2) Size of HCC and(3) multifocal tumors. The median 5-year OS of BCLC stage B was 38.7%(range 10.0-57.0); while the median 5-year OS of BCLC stage C was 20.0%(range 0.0-42.0). The collective median 5-year OS of both stages was 27.9%(0.0-57.0). In examining the morbidity and mortality following liver resection in large HCC, the pooled RR for morbidity [RR(95%CI) = 1.00(0.76-1.31)] and mortality [RR(95%CI) = 1.15(0.73-1.80)] were not significant. Within the spectrum of BCLC B and C lesions, tumors greater than 10 cm were reported to have median 5-year OS of 33.0% and multifocal lesions 54.0%.CONCLUSION Indication for surgical resection should be extended to BCLC stage B lesions in selected patients. Further studies are needed to stratify stage C lesions for resection. | Ye Xin Koh Hwee Leong Tan Weng Kit Lye Juinn Huar Kam Adrian Kah Heng Chiow Siong San Tan Su Pin Choo Alexander Yaw Fui Chung Brian Kim Poh Goh | 2018 | World Journal of Hepatology2018，10，6： | 10 |
| 3 | Biofilm Microenvironment-Responsive Nanotheranostics for Dual-Mode Imaging and Hypoxia-Relief-Enhanced Photodynamic Therapy of Bacterial Infections显示文摘The formation of bacterial biofilms closely associates with infectious diseases.Until now,precise diagnosis and effective treatment of bacterial biofilm infections are still in great need.Herein,a novel multifunctional theranostic nanoplatform based on MnO_(2)nanosheets(MnO_(2)NSs)has been designed to achieve pH-responsive dual-mode imaging and hypoxia-relief-enhanced antimicrobial photodynamic therapy(aPDT)of bacterial biofilm infections.In this study,MnO_(2)NSs were modified with bovine serum albumin(BSA)and polyethylene glycol(PEG)and then loaded with chlorin e_(6)(Ce_(6))as photosensitizer to form MnO_(2)-BSA/PEG-Ce_(6)nanosheets(MBP-Ce_(6)NSs).After being delivered into the bacterial biofilm-infected tissues,the MBP-Ce_(6)NSs could be decomposed in acidic biofilm microenvironment and release Ce_(6)with Mn^(2+),which subsequently activate both fluorescence(FL)and magnetic resonance(MR)signals for effective dual-mode FL/MR imaging of bacterial biofilm infections.Meanwhile,MnO_(2)could catalyze the decomposing of H2O_(2)in biofilm-infected tissues into O_(2)and relieve the hypoxic condition of biofilm,which significantly enhances the efficacy of aPDT.An in vitro study showed that MBP-Ce_(6)NSs could significantly reduce the number of methicillin-resistant Staphylococcus aureus(MRSA)in biofilms after 635nm laser irradiation.Guided by FL/MR imaging,MRSA biofilm-infected mice can be efficiently treated by MBP-Ce_(6)NSs-based aPDT.Overall,MBP-Ce_(6)NSs not only possess biofilm microenvironment-responsive dual-mode FL/MR imaging ability but also have significantly enhanced aPDT efficacy by relieving the hypoxia habitat of biofilm,which provides a promising theranostic nanoplatform for bacterial biofilm infections. | Weijun Xiu Siyu Gan Qirui Wen Qiu Qiu Sulai Dai Heng Dong Qiang Li Lihui Yuwen Lixing Weng Zhaogang Teng Yongbin Mou Lianhui Wang | 2020 | Research2020，，1： | 7 |

| 6 | Validation of different personalized risk models of chemotherapy-induced nausea and vomiting:results of a randomized,double-blind,phase III trial of fosaprepitant for cancer patients treated with high-dose cisplatin显示文摘Background:Highly emetogenic chemotherapy induces emesis in cancer patients without prophylaxis.The purpose of this study was to evaluate the efficacy and safety of a fosaprepitant-based triple antiemetic regimen for the prevention of chemotherapy-induced nausea and vomiting(CINV)in patients with solid malignant tumors,determine risk factors and externally validate different personalized risk models for CINV.Methods:This phase III trial was designed to test the non-inferiority of fosaprepitant toward aprepitant in cancer patients who were to receive the first cycle of single-day cisplatin chemotherapy.The primary endpoint was complete response(CR)during the overall phase(OP)with a non-inferiority margin of 10.0%.Logistic regression modelswere used to assess the risk factors ofCRand no nausea.To validate the personalized risk models,the accuracy of the risk scoring systems was determined by measuring the specificity,sensitivity and area under the receiver operating characteristic(ROC)curve(AUC),while the predictive accuracy of the nomogram was measured using concordance index(C-index).Results:A total of 720 patients were randomly assigned.CR during the OP in the fosaprepitant group was not inferior to that in the aprepitant group(78.1%vs.77.7%,P=0.765)with a between-group difference of 0.4%(95%CI,-5.7%to 6.6%).Female sex,higher cisplatin dose(≥70 mg/m2),no history of drinking and larger body surface area(BSA)were significantly associated with nausea.The AUC for the acute and delayed CINV risk indexes was 0.68(95%CI:0.66-0.71)and 0.66(95%CI:0.61-0.70),respectively,and the C-index for nomogram CINV prediction was 0.59(95%CI,0.54-0.64).Using appropriate cutoff points,the three models could stratify patients with high-or low-risk CINV.No nausea and CR rate were significantly higher in the low-risk group than in the high-risk group(P<0.001).Conclusions:Fosaprepitant-based triple prophylaxis demonstrated non-inferior control for preventing CINV in patients treated with cisplatin-base chemotherapy.Female cancer patients without a history of alcohol consumption,with larger BSA and received high-dose cisplatin might be more vulnerable to CINV.Three personalized prediction models were well-validated and could be used to optimize antiemetic therapy for individual patients. | Yuanyuan Zhao Bing Zhao Gang Chen Yinlan Chen Zijun Liao Haiming Zhang Weineng Feng Yinyin Li Heng Weng Weidong Li Yuefen Zhou Biyong Ren Yanda Lu Jianhua Chen Zhenteng Liu Zhenzhong Su Wenliang Wang Li Zhang | 2023 | Cancer Communications2023，43，2： | 2 |

| 13 | Method for the extraction of circulating nucleic acids based on MOF reveals cell-free RNA signatures in liver cancer显示文摘Cell-free RNA(cf RNA) allows assessment of health, status, and phenotype of a variety of human organs and is a potential biomarker to non-invasively diagnose numerous diseases. Nevertheless, there is a lack of highly efficient and bias-free cf RNA isolation technologies due to the low abundance and instability of cf RNA.Here, we developed a reproducible and high-efficiency isolation technology for different types of cell-free nucleic acids(containing cf RNA and viral RNA) in serum/plasma based on the inclusion of nucleic acids by metal-organic framework(MOF) materials, which greatly improved the isolation efficiency and was able to preserve RNA integrity compared with the most widely used research kit method. Importantly, the quality of cf RNA extracted by the MOF method is about 10-fold that of the kit method, and the MOF method isolates more than three times as many different RNA types as the kit method. The whole transcriptome mapping characteristics of cf RNA in serum from patients with liver cancer was described and a cf RNA signature with six cf RNAs was identified to diagnose liver cancer with high diagnostic efficiency(area under curve = 0.905 in the independent validation cohort) using this MOF method. Thus, this new MOF isolation technique will advance the field of liquid biopsy, with the potential to diagnose liver cancer. | Yuqing Sun Haixin Yu Shaoqing Han Ruoxi Ran Ying Yang Yongling Tang Yuhao Wang Wenhao Zhang Heng Tang Boqiao Fu Boshi Fu Xiaocheng Weng Song-Mei Liu Hexiang Deng Shuang Peng Xiang Zhou | 2024 | National Science Review2024，11，1： | 0 |

| 15 | A neuropsin-based optogenetic tool for precise control of Gq signaling显示文摘G_(q)-coupled receptors regulate numerous physiological processes by activating enzymes and inducing intracellular Ca^(2+)signals.There is a strong need for an optogenetic tool that enables powerful experimental control over G_(q) signaling.Here,we present chicken opsin 5(cOpn5)as the long sought-after,single-component optogenetic tool that mediates ultra-sensitive optical control of intracellular G_(q) signaling with high temporal and spatial resolution.Expressing cOpn5 in HEK 293T cells and primary mouse astrocytes enables blue light-triggered,G_(q)-dependent Ca^(2+) release from intracellular stores and protein kinase C activation.Strong Ca^(2+) transients were evoked by brief light pulses of merely 10 ms duration and at 3 orders lower light intensity of that for common optogenetic tools.Photostimulation of cOpn5-expressing cells at the subcellular and single-cell levels generated fast intracellular Ca^(2+)transition,thus demonstrating the high spatial precision of cOpn5 optogenetics.The cOpn5-mediated optogenetics could also be applied to activate neurons and control animal behavior in a circuit-dependent manner.cOpn5 optogenetics may find broad applications in studying the mechanisms and functional relevance of G_(q) signaling in both non-excitable cells and excitable cells in all major organ systems. | Ruicheng Dai Tao Yu Danwei Weng Heng Li Yuting Cui Zhaofa Wu Qingchun Guo Haiyue Zou Wenting Wu Xinwei Gao Zhongyang Qi Yuqi Ren Shu Wang Yulong Li Minmin Luo | 2022 | Science China(Life Sciences)2022，65，7： | 0 |

| 18 | Lipopolysaccharide-induced podocyte injury is regulated by calcineurin/NFAT and TLR4/MyD88/NF-κB signaling pathways through angiopoietin-like protein 4显示文摘Podocyte injury is an important cause of proteinuria.Angiopoietin-like protein 4(Angptl4)is a secreted glycoprotein and has a role in proteinuria.However,the exact role of Angptl4 in podocyte injury and its upstream regulators has not been clarified.In this study,we used lipopolysaccharide(LPS)-induced mice and cultured podocytes as podocyte injury models.Our results indicated that LPS increased the expression of podocyte Angptl4 in vivo and in vitro.Furthermore,we showed that Angptl4 overexpression deteriorated LPS-induced podocyte injury by inducing podocyte cytoskeleton rearrangement,reducing the expression of synaptopodin while Angptl4 knockdown alleviated LPS-induced podocyte injury.In addition,we found that inhibitors and siRNA targeting TLR4/MyD88/NF-κB signaling inhibited the upregulation of Angptl4 in LPS-induced podocytes.Moreover,inhibitors and siRNA targeting calcineurin/NFAT signaling also relieved LPS-induced Angptl4 expression and podocyte injury in vivo and in vitro.Taken together,our study has elucidated that both of the TLR4/MyD88/NF-κB and calcineurin/NFAT signaling mediate the upregulation of Angptl4 in LPS-induced podocytes,which has important implications for further understanding the molecular mechanism of LPS-induced podocyte injury. | Xiujin Shen Chunhua Weng Yucheng Wang Cuili Wang Shi Feng Xiayu Li Heng Li Hong Jiang Haibing Wang Jianghua Chen | 2022 | Genes & Diseases2022，9，2： | 0 |
| 19 | Dynamical and allosteric regulation of photoprotection in light harvesting complex Ⅱ显示文摘Major light-harvesting complex of photosystemⅡ(LHCⅡ)plays a dual role in light-harvesting and excited energy dissipation to protect photodamage from excess energy.The regulatory switch is induced by increased acidity,temperature or both.However,the molecular origin of the protein dynamics at the atomic level is still unknown.We carried out temperature-jump time-resolved infrared spectroscopy and molecular dynamics simulations to determine the energy quenching dynamics and conformational changes of LHCⅡtrimers.We found that the spontaneous formation of a pair of localα-helices from the 310-helix E/loop and the C-terminal coil of the neighboring monomer,in response to the increased environmental temperature and/or acidity,induces a scissoring motion of transmembrane helices A and B,shifting the conformational equilibrium to a more open state,with an increased angle between the associated carotenoids.The dynamical and allosteric conformation change leads to close contacts between carotenoid lutein 1 and chlorophyll pigment 612,facilitating the fluorescence quenching.Based on these results,we suggest a unified mechanism by which the LHCⅡtrimer controls the dissipation of excess excited energy in response to increased temperature and acidity,as an intrinsic result of intense sun light in plant photosynthesis. | Hao Li Yingjie Wang Manping Ye Shanshan Li Deyong Li Haisheng Ren Mohan Wang Luchao Du Heng Li Gianluigi Veglia Jiali Gao Yuxiang Weng | 2020 | Science China Chemistry2020，63，8： | 0 |
| 20 | Biochemical recurrence of pathological T2+localized prostate cancer after robotic-assisted radical prostatectomy:A 10-year surveillance显示文摘BACKGROUND pT2+prostate cancer(PCa),a term first used in 2004,refers to organ-confined PCa characterized by a positive surgical margin(PSM)without extracapsular extension.Patients with a PSM are vulnerable to biochemical recurrence(BCR)following radical prostatectomy(RP);however,whether adjuvant radiotherapy(aRT)is imperative to PSM after RP remains controversial.This study had the longest follow-up on pT2+PCa after robotic-assisted RP since 2004.Moreover,we discussed our viewpoints on pT2+PCa based on real-world experiences.AIM To conclude a 10-year surveillance on pT2+PCa and compare our results with those of the published literature.METHODS Forty-eight patients who underwent robotic-assisted RP between 2008 and 2011 were enrolled.Two serial tests of prostate specific antigen(PSA)≥0.2 ng/mL were defined as BCR.Various designed factors were analyzed using statistical tools for BCR risk.SAS 9.4 was applied and significance was defined as P<0.05.Univariate,multivariate,linear regression,and receiver operating characteristic(ROC)curve analyses were performed for statistical analyses.RESULTS With a median follow-up period of 9 years,25(52%)patients had BCR(BCR group),and the remaining 23(48%)patients did not(non-BCR group).The median time for BCR test was 4 years from the first postoperative PSA nadir.Preoperative PSA was significantly different between the BCR and non-BCR groups(P<0.001),and ROC curve analysis of preoperative PSA suggested a cutoff value of 19.09 ng/mL(sensitivity,0.600;specificity:0.739).The linear regression analysis showed no correlation between time to BCR and preoperative PSA(Pearson’s correlation,0.13;adjusted R2=0.026).CONCLUSION Robotic-assisted RP in pT2+PCa of worse conditions can provide better BCR-free survival.A surgical technique limiting the PSM in favorable situations is warranted to lower the pT2+PCa BCR rate.Preoperative PSA cut-off value of 19.09 ng/mL is a predictive factor for BCR.Based on our experiences and review of the literature,we do not recommend routine aRT for pT2+PCa. | Che Hseuh Yang Yi Sheng Lin Yen Chuan Ou Wei Chun Weng Li Hua Huang Chin Heng Lu Chao Yu Hsu Min Che Tung | 2021 | World Journal of Clinical Cases2021，9，5： | 0 |
