| 1 | Pathological evidence for residual SARS-CoV-2 in pulmonary tissues of a ready-for-discharge patient显示文摘Dear Editor,SARS-CoV-2,a novel coronavirus and causing COVID-19,has given rise to a worldwide pandemic.1,2 So far,tens of thousands of COVID-19 patients have been clinically cured and discharged,but multiple COVID-19 cases showed SARS-CoV-2 positive again in discharged patients,3 which raises an attention for the discharged patients.Also,there is an urgent need to understand the pathogenesis of SARS-CoV-2 infection.Here,we conducted postmortem pathologic study in a ready-fordischarge COVID-19 patient who succumbed to sudden cardiovascular accident.Pathological examination revealed SARSCoV-2-viruses remaining in pneumocytes and virus-caused pathological changes in the lungs.Our study provided new insights into SARS-CoV-2 pathogenesis and might facilitate the improvement of clinical guideline for virus containment and disease management. | Xiao-Hong Yao Zhi-Cheng He Ting-Yuan Li Hua-Rong Zhang Yan Wang Huaming Mou Qiaonan Guo Shi-Cang Yu Yanqing Ding Xindong Liu Yi-Fang Ping Xiu-Wu Bian | 2020 | Cell Research2020，30，6： | 35 |
| 2 | Evaluation of epithelial-mesenchymal transitioned circulating tumor cells in patients with resectable gastric cancer: Relevance to therapy response显示文摘AIM: To evaluate the epithelial-to-mesenchymal transition(EMT) of circulating tumor cells(CTCs) in gastric cancer patients.METHODS: We detected tumor cells for expression of four epithelial(E^+) transcripts(keratins 8, 18, and 19 and epithelial cell adhesion molecule) and two mesenchymal(M^+) transcripts(Vimentin and Twist) by a quantifiable, dual-colorimetric RNA-in situ hybridization assay. Between July 2014 and October 2014, 44 patients with gastric cancer were recruited for CTC evaluation. Blood samples were obtained from selected patients during the treatment course [before surgery, after surgery and at the 6^(th) cycle of XELOX based chemotherapy(about 6 mo postoperatively)].RESULTS: We found the EMT phenomenon in which there were a few biphenotypic E^+/M^+ cells in primary human gastric cancer specimens. Of the 44 patients, the presence of CTCs was reported in 35(79.5%) patients at baseline. Five types of cells including from exclusively E^+ CTCs to intermediate CTCs and exclusively M^+ CTCs were identified(4 patients with M^+ CTCs and 10 patients with M^+ or M^+ > E^+ CTCs). Further, a chemotherapy patient having progressive disease showed a proportional increase of mesenchymal CTCs in the post-treatment blood specimens. We used NCI-N87 cells to analyze the linearity and sensitivity of Can Patrol^(TM) system and the correlation coefficient(R^2) was 0.999.CONCLUSION: The findings suggest that the EMT phenomenon was both in a few cells of primary tumors and abundantly in CTCs from the blood of gastric cancer patients, which might be used to monitor therapy response. | Ting-Ting Li Hao Liu Feng-Ping Li Yan-Feng Hu Ting-Yu Mou Tian Lin Jiang Yu Lei Zheng Guo-Xin Li | 2015 | World Journal of Gastroenterology2015，21，47： | 29 |
| 3 | Laparoscopic vs open D2 gastrectomy for locally advanced gastric cancer: A meta-analysis显示文摘AIM:To conduct a meta-analysis comparing laparoscopic(LGD2)and open D2 gastrectomies(OGD2)for the treatment of advanced gastric cancer(AGC).METHODS:Randomized controlled trials(RCTs)and non-RCTs comparing LGD2 with OGD2 for AGC treatment,published between 1 January 2000 and 12January 2013,were identified in the Pub Med,Embase,and Cochrane Library databases.Primary endpoints included operative outcomes(operative time,intraoperative blood loss,and conversion rate),postoperative outcomes(postoperative analgesic consumption,time to first ambulation,time to first flatus,time to first oralintake,postoperative hospital stay length,postoperative morbidity,incidence of reoperation,and postoperative mortality),and oncologic outcomes(the number of lymph nodes harvested,tumor recurrence and metastasis,disease-free rates,and overall survival rates).The Cochrane Collaboration tools and the modified Newcastle-Ottawa scale were used to assess the quality and risk of bias of RCTs and non-RCTs in the study.Subgroup analyses were conducted to explore the incidence rate of various postoperative morbidities as well as recurrence and metastasis patterns.A Begg’s test was used to evaluate the publication bias.RESULTS:One RCT and 13 non-RCTs totaling 2596patients were included in the meta-analysis.LGD2 in comparison to OGD2 showed lower intraoperative blood loss[weighted mean difference(WMD)=-137.87 m L,95%CI:-164.41--111.33;P<0.01],lower analgesic consumption(WMD=-1.94,95%CI:-2.50--1.38;P<0.01),shorter times to first ambulation(WMD=-1.03d,95%CI:-1.90--0.16;P<0.05),flatus(WMD=-0.98d,95%CI:-1.30--0.66;P<0.01),and oral intake(WMD=-0.85 d,95%CI:-1.67--0.03;P<0.05),shorter hospitalization(WMD=-3.08 d,95%CI:-4.38--1.78;P<0.01),and lower postoperative morbidity(odds ratio=0.78,95%CI:0.61-0.99;P<0.05).No significant differences were observed between LGD2 and OGD2 for the following criteria:reoperation incidence,postoperative mortality,number of harvested lymph nodes,tumor recurrence/metastasis,or three-or five-year diseasefree and overall survival rates.However,LGD2 had longer operative times(WMD=57.06 min,95%CI:41.87-72.25;P<0.01).CONCLUSION:Although a technically demanding and time-consuming procedure,LGD2 may be safe and effective,and offer some advantages over OGD2 for treatment of locally AGC. | Zhen-Hong Zou Li-Ying Zhao Ting-Yu Mou Yan-Feng Hu Jiang Yu Hao Liu Hao Chen Jia-Ming Wu Sheng-Li An Guo-Xin Li | 2014 | World Journal of Gastroenterology2014，20，44： | 25 |
| 4 | Systematic review and meta-analysis of laparoscopy-assisted and open total gastrectomy for gastric cancer显示文摘AIM:To evaluate the safety and efficacy of laparoscopy-assisted total gastrectomy(LATG)and open total gastrectomy(OTG)for gastric cancer.METHODS:A comprehensive search of PubMed,Cochrane Library,Web of Science and BIOSIS Previews was performed to identify studies that compared LATG and OTG.The following factors were checked:operating time,blood loss,harvested lymph nodes,flatus time,hospital stay,mortality and morbidity.Data synthesis and statistical analysis were carried out using RevMan 5.1 software.RESULTS:Nine studies with 1221 participants were included(436 LATG and 785 OTG).Compared to OTG,LATG involved a longer operating time[weighted mean difference(WMD)=57.68 min,95%CI:30.48-84.88;P<0.001];less blood loss[standard mean difference(SMD)=-1.71;95%CI:-2.48--0.49;P<0.001];earlier time to flatus(WMD=-0.76 d;95%CI:-1.22--0.30;P<0.001);shorter hospital stay(WMD=-2.67d;95%CI:-3.96--1.38,P<0.001);and a decrease in medical complications(RR=0.41,95%CI:0.19-0.90,P=0.03).The number of harvested lymph nodes,mortality,surgical complications,cancer recurrence rate and long-term survival rate of patients undergoing LATG were similar to those in patients undergoing OTG.CONCLUSION:Despite a longer operation,LATG can be performed safely in experienced surgical centers with a shorter hospital stay and fewer complications than open surgery. | Ke Chen Xiao-Wu Xu Ren-Chao Zhang Yu Pan Di Wu Yi-Ping Mou | 2013 | World Journal of Gastroenterology2013，19，32： | 23 |
| 5 | Totally laparoscopic gastrectomy for gastric cancer: A systematic review and meta-analysis of outcomes compared with open surgery显示文摘AIM:To systematically review the surgical outcomes of totally laparoscopic gastrectomy(TLG)vs open gastrectomy(OG)for gastric cancer.METHODS:A systematic search of PubMed,Embase,Cochrane Library,and Web of Science was conducted.All original studies comparing TLG with OG were included for critical appraisal.Data synthesis and statistical analysis were carried out using RevMan 5.1 software.RESULTS:One RCT and 13 observational studies involving 1532 patients were included(721 TLG and811 OG).TLG was associated with longer operation time[weighted mean difference(WMD)=58.04min,95%CI:37.77-78.32,P<0.001],less blood loss[WMD=-167.57 min,95%CI:-208.79-(-126.34),P<0.001],shorter hospital stay[WMD=-3.75 d,95%CI:-4.88-(-2.63),P<0.001]and fewer postoperative complications(RR=0.71,95%CI:0.58-0.86,P<0.001).The number of harvested lymph nodes,surgical margin,mortality and cancer recurrence rate were similar between the two groups.CONCLUSION:TLG may be a technically safe,feasible and favorable approach in terms of better cosmesis,less blood loss and faster recovery compared with OG. | Ke Chen Yu Pan Jia-Qin Cai Xiao-Wu Xu Di Wu Yi-Ping Mou | 2014 | World Journal of Gastroenterology2014，20，42： | 19 |
| 6 | Staging laparoscopy improves treatment decision-makingfor advanced gastric cancer显示文摘AIM To evaluate the clinical value of staging laparoscopyin treatment decision-making for advancedgastric cancer (GC).METHODS: Clinical data of 582 patients with advancedGC were retrospectively analyzed. All patientsunderwent staging laparoscopy. The strength ofagreement between computed tomography (CT) stage,endoscopic ultrasound (EUS) stage, laparoscopic stage,and final stage were determined by weighted Kappastatistic (Kw). The number of patients with treatmentdecision-changes was counted. A χ 2 test was used toanalyze the correlation between peritoneal metastasisor positive cytology and clinical characteristics.RESULTS: Among the 582 patients, the distributions ofpathological T classifications were T2/3 (153, 26.3%),T4a (262, 45.0%), and T4b (167, 28.7%). Treatmentplans for 211 (36.3%) patients were changed after staging laparoscopy was performed. Two (10.5%) of19 patients in M1 regained the opportunity for potentialradical resection by staging laparoscopy. Unnecessarylaparotomy was avoided in 71 (12.2%) patients. Thestrength of agreement between preoperative T stageand final T stage was in almost perfect agreement (Kw= 0.838; 95% confidence interval (CI): 0.803-0.872;P 〈 0.05) for staging laparoscopy; compared with CTand EUS, which was in fair agreement. The strengthof agreement between preoperative M stage andfinal M stage was in almost perfect agreement (Kw= 0.990; 95% CI: 0.977-1.000; P 〈 0.05) for staginglaparoscopy; compared with CT, which was in slightagreement. Multivariate analysis revealed that tumorsize (≥ 40 mm), depth of tumor invasion (T4b), andBorrmann type (Ⅲ or Ⅳ) were significantly correlatedwith either peritoneal metastasis or positive cytology.The best performance in diagnosing P-positive wasobtained when two or three risk factors existed.CONCLUSION: Staging laparoscopy can improvetreatment decision-making for advanced GC anddecrease unnecessary exploratory laparotomy. | Yan-Feng Hu Zhen-Wei Deng Hao Liu Ting-Yu Mou Tao Chen Xin Lu Da Wang Jiang Yu Guo-Xin Li | 2016 | World Journal of Gastroenterology2016，22，5： | 17 |
| 7 | Case-matched comparison of laparoscopy-assisted and open distal gastrectomy for gastric cancer显示文摘AIM: To compare shortand long-term outcomes of laparoscopy-assisted and open distal gastrectomy for gastric cancer. METHODS: A retrospective study was performed by comparing the outcomes of 54 patients who underwent laparoscopy-assisted distal gastrectomy (LADG) with those of 54 patients who underwent open distal gastrectomy (ODG) between October 2004 and October 2007. The patients' demographic data (age and gender), date of surgery, extent of lymphadenectomy, and differentiation and tumor-node-metastasis stage of the tumor were examined. The operative time, intraoperative blood loss, postoperative recovery, complications, pathological findings, and follow-up data were compared between the two groups.RESULTS: The mean operative time was significantly longer in the LADG group than in the ODG group (259.3 ± 46.2 min vs 199.8 ± 40.85 min; P < 0.05), whereas intraoperative blood loss and postoperative complications were significantly lower (160.2 ± 85.9 mL vs 257.8 ± 151.0 mL; 13.0% vs 24.1%, respectively, P < 0.05). In addition, the time to first flatus, time to initiate oral intake, and postoperative hospital stay were significantly shorter in the LADG group than in the ODG group (3.9 ± 1.4 d vs 4.4 ± 1.5 d; 4.6 ± 1.2 d vs 5.6 ± 2.1 d; and 9.5 ± 2.7 d vs 11.1 ± 4.1 d, respectively; P < 0.05). There was no significant difference between the LADG group and ODG group with regard to the number of harvested lymph nodes. The median followup was 60 mo (range, 5-97 mo). The 1-, 3-, and 5-year disease-free survival rates were 94.3%, 90.2%, and 76.7%, respectively, in the LADG group and 89.5%, 84.7%, and 82.3%, respectively, in the ODG group. The 1-, 3-, and 5-year overall survival rates were 98.0%, 91.9%, and 81.1%, respectively, in the LADG group and 91.5%, 86.9%, and 82.1%, respectively, in the ODG group. There was no significant difference between the two groups with regard to the survival rate. CONCLUSION: LADG is suitable and minimally invasive for treating distal gastric cancer and can achieve similar long-term results to ODG. | Wei Wang Ke Chen Xiao-Wu Xu Yu Pan Yi-Ping Mou | 2013 | World Journal of Gastroenterology2013，19，23： | 15 |
| 8 | Intracorporeal esophagojejunostomy after totally laparoscopic total gastrectomy: A single-center 7-year experience显示文摘AIM: To assess the efficacy and safety of intracorporeal esophagojejunostomy in patients undergoing laparoscopic total gastrectomy(LTG) for gastric cancer.METHODS: A retrospective review of 81 consecutive patients who underwent LTG with the same surgical team between November 2007 and July 2014 was performed. Four types of intracorporeal esophagojejunostomy using staplers or hand-sewn suturing were performed after LTG. Data on clinicopatholgoical characteristics, occurrence of complications, postoperative recovery, anastomotic time, and operation time among the surgical groups were obtained through medical records.RESULTS: The average operation time was 288.7 min, the average anastomotic time was 54.3 min, and the average estimated blood loss was 82.7 m L. There were no cases of conversion to open surgery. The first flatus was observed around 3.7 d, while the liquid diet was started, on average, from 4.9 d. The average postoperative hospital stay was 10.1 d. Postoperative complications occurred in 14 patients, nearly 17.3%.However, there were no cases of postoperative death.CONCLUSION: LTG performed with intracorporeal esophagojejunostomy using laparoscopic staplers or hand-sewn suturing is feasible and safe. The surgical results were acceptable from the perspective of minimal invasiveness. | Ke Chen Yu Pan Jia-Qin Cai Xiao-Wu Xu Di Wu Jia-Fei Yan Rong-Gao Chen Yang He Yi-Ping Mou | 2016 | World Journal of Gastroenterology2016，22，12： | 14 |
| 9 | Laparoscopic splenic hilum lymph node dissection for advanced proximal gastric cancer:A modified approach for pancreasand spleen-preserving total gastrectomy显示文摘AIM:To investigate the feasibility and optimal approach for laparoscopic pancreasand spleen-preserving splenic hilum lymph node dissection in advanced proximal gastric cancer.METHODS:Between August 2009 and August 2012,12 patients with advanced proximal gastric cancer treated in Nanfang Hospital,Southern Medical University,Guangzhou,China were enrolled and subsequently underwent laparoscopic total gastrectomy with pancreasand spleen-preserving splenic hilum lymph node(LN)dissection.The clinicopathological characteristics,surgical outcomes,postoperative course and followup data of these patients were retrospectively collected and analyzed in the study.RESULTS:Based on our anatomical understanding of peripancreatic structures,we combined the characteristics of laparoscopic surgery and developed a modified approach(combined supraand infra-pancreatic approaches)for laparoscopic pancreasand spleenpreserving splenic hilum LN dissection.Surgery was completed in all 12 patients laparoscopically without conversion.Only one patient experienced intraoperative bleeding when dissecting LNs along the splenic artery and was handled with laparoscopic hemostasis.The mean operating time was 268.4 min and mean number of retrieved splenic hilum LNs was 4.8.One patient had splenic hilum LN metastasis(8.3%).Neither postoperative morbidity nor mortality was observed.Peritoneal metastasis occurred in one patient and none of the other patients died or experienced recurrent disease during the follow-up period.CONCLUSION:Laparoscopic total gastrectomy with pancreasand spleen-preserving splenic hilum LN dissection using the modified approach for advanced proximal gastric cancer could be safely achieved. | Ting-Yu Mou Yan-Feng Hu Jiang Yu Hao Liu Ya-Nan Wang Guo-Xin Li | 2013 | World Journal of Gastroenterology2013，19，30： | 13 |
| 10 | Adaptive dynamic surface control of NSVs with input saturation using a disturbance observer显示文摘An adaptive dynamic surface control(DSC)scheme is proposed for the multi-input and multi-output(MIMO)attitude motion of near-space vehicles(NSVs)in the presence of external disturbance,system uncertainty and input saturation.The external disturbance and the system uncertainty are efficiently tackled using a Nussbaum disturbance observer(NDO),and the adaptive controller is constructed by combining the dynamic surface control technique to handle the problem of‘‘explosion of complexity’’inherent in the conventional backstepping method.For handling the input saturation,an auxiliary system is designed with the same order as that of the studied MIMO attitude system.Using the error between the saturation input and the desired control input as the input of the designed auxiliary system,a series of signals are generated to compensate for the effect of the saturation in the dynamic surface control design.It is proved that the developed control scheme can guarantee that all signals of the closed-loop control system are semi-globally uniformly bounded.Finally,simulation results illustrate that the proposed control scheme can achieve satisfactory tracking performance under the composite effects of the input saturation and the external disturbance. | Chen Mou Yu Jing | 2015 | Chinese Journal of Aeronautics2015，28，3： | 12 |
| 11 | Sedimentary Facies and Distribution of Reservoir Rocks from the Feixianguan Formation in the Daxian-Xuanhan Region, NE Sichuan显示文摘The Lower Triassic Feixianguan Formation in the Daxian-Xuanhan region, northeastern Sichuan is interpreted to be a carbonate platform intermediate between the West Hubei-East Chongqing marine basin and Guangyuan-Wangcang marine basin. Outcrops, well logs and seismic data have disclosed that three sedimentary facies can be identified for the formation: open platform, platform exposed shoal and restricted platform facies. During the early stage of deposition of the Feixianguan Formation, there existed a sedimentary framework all the same as the Late Permian one: open platform in the west, and platform exposed shoal, restricted platform and open platform eastwards. The gradual increase of the shoal area permitted eastward migration of the shoal facies. During the deposition of the third member of the Feixianguan Formation, the study area was invaded by temporary transgressions. Till the deposition of the fourth member of the formation, the study area was prevailed over the unified restricted platform deposits, as indicated by the sedimentary model for the typical carbonate platform shoal deposits. The reservoir rocks in the Feixianguan Formation consist mostly of solution opening dolostone, and the rock types are assembled by oolitic dolostone, residual oolitic dolostone and sucrosic residual oolitic medium- to coarse-grained dolostone. The deep and shallow dual laterologs show relatively high resistivity, clear amplitude differences and time difference saltation of acoustic waves in some intervals. The seismic responses are indicated by low-frequency and highly variable amplitudes and chaotic reflection configurations. The reservoir rocks are characterized by high porosity-high permeability and medium porosity-medium permeability, showing a marked correlation between porosity and permeability. Solution openings are extremely developed in the reservoir rocks, including cast pores, intergranular solution openings, intercrystal pores, intercrystal solution openings, solution openings (caves) and minute fissures. Macropores and coarse pore throats are common. The reservoir rocks are apparently controlled by sedimentary facies in distribution patterns. Vertically, they occur dominantly in the second and first members of the Feixianguan Formation, and laterally in the platform exposed shoals and restricted platforms, where good natural gas potential is expected. | MA Yongsheng MOU Chuanlong GUO Xusheng YU Qian TAN Qinyin | 2006 | Acta Geologica Sinica(English Edition)2006，80，1： | 11 |
| 12 | Analysis and improvement of missile three-loop autopilots显示文摘The non-minimum phase feature of tail-controlled missile airframes is analyzed.Three selection strategies for desired performance indexes are presented.An acceleration autopilot design methodology based on output feedback and optimization is proposed.Performance and robustness comparisons between the two-loop and classical three-loop topologies are made.Attempts to improve the classical three-loop topology are discussed.Despite the same open-loop structure,the classical three-loop autopilot shows distinct characteristics from a two-loop autopilot with PI compensator.Both the two-loop and three-loop topologies can stabilize a static unstable missile.However, the finite actuator resource is the crucial factor dominating autopilot function. | Lin Defu Fan Junfang Qi Zaikang Mou Yu | 2009 | Journal of Systems Engineering and Electronics2009，20，4： | 10 |
| 13 | Nitrogen Biological Cycle Characteristics of Seepweed(Suaeda salsa) Wetland in Intertidal Zone of Huanghe(Yellow) River Estuary显示文摘From April 2008 to November 2009,the nitrogen(N) cycle of plantsoil system in seepweed(Suaeda salsa) wetland in the intertidal zone of the Huanghe(Yellow) River estuary was studied.Results showed that soil N had sig-nificant seasonal fluctuations and vertical distribution,and the net N mineralization rates in topsoil were significantly different in growing season(p < 0.01).The N/P ratio(9.87 ± 1.23) of S.salsa was less than 14,indicating that plant growth was limited by N.The N accumulated in S.salsa litter at all times during decomposition,which was ascribed to the N immobilization by microbes from the environment.Soil organic N was the main N stock of plant-soil system,accounting for 97.35% of the total N stock.The N absorption and utilization coefficients of S.salsa were very low(0.0145 and 0.3844,respectively),while the N cycle coefficient was high(0.7108).The results of the N turnovers among compartments of S.salsa wetland showed that the N uptake amount of aboveground part and root were 7.764 g/m2and 4.332 g/m2,respectively.The N translocation amounts from aboveground part to root and from root to soil were 3.881 g/m2 and 0.626 g/m2,respectively.The N translocation amount from aboveground living body to litter was 3.883 g/m2,the annual N return amount from litter to soil was more than 0.125(-) g/m2(minus represented immobilization),and the net N mineralization amount in topsoil(0-15 cm) in growing season was 1.190 g/m2.The assessment of N biological cycle status of S.salsa wetland indicated that N was a very important limiting factor and the ecosystem was situated in unstable and vulnerable status.The S.salsa was seemingly well adapted to the low-nutrient status and vulnerable habitat,and the N quantitative relationships determined in the compartment model might provide scientific base for us to reveal the special adaptive strategy of S.salsa to the vulnerable habitat in the following studies. | SUN Zhigao MOU Xiaojie SUN Jingkuan SONG Hongli YU Xiang WANG Lingling JIANG Huanhuan SUN Wanlong SUN Wenguang | 2012 | Chinese Geographical Science2012，22，1： | 9 |
| 14 | Prognostic value and nomograms of proximal margin distance in gastric cancer with radical distal gastrectomy显示文摘Objective:The proximal margin(PM)distance for distal gastrectomy(DG)of gastric cancer(GC)remains controversial.This study investigated the prognostic value of PM distance for survival outcomes,and aimed to combine clinicopathologic variables associated with survival outcomes after DG with different PM distance for GC into a prediction nomogram.Methods:Patients who underwent radical DG from June 2004 to June 2014 at Department of General Surgery,Nanfang Hospital,Southern Medical University were included.The first endpoints of the prognostic value of PM distance(assessed in 0.5 cm increments)for disease-free survival(DFS)and overall survival(OS)were assessed.Multivariate analysis by Cox proportional hazards regression was performed using the training set,and the nomogram was constructed,patients were chronologically assigned to the training set for dates from June 1,2004 to January 30,2012(n=493)and to the validation set from February 1,2012 to June 30,2014(n=211).Results:Among 704 patients with p TNM stage I,p TNM stage II,T1-2,T3-4,N0,differentiated type,tumor size≤5.0 cm,a PM of(2.1-5.0)cm vs.PM≤2.0 cm showed a statistically significant difference in DFS and OS,while a PM>5.0 cm was not associated with any further improvement in DFS and OS vs.a PM of 2.1-5.0 cm.In patients with p TNM stage III,N1,N2-3,undifferentiated type,tumor size>5.0 cm,the PM distance was not significantly correlated with DFS and OS between patients with a PM of(2.1-5.0)cm and a PM≤2 cm,or between patients with a PM>5.0 cm and a PM of(2.1-5.0)cm,so there were no significant differences across the three PM groups.In the training set,the C-indexes of DFS and OS,were 0.721 and 0.735,respectively,and in the validation set,the C-indexes of DFS and OS,were 0.752 and 0.751,respectively.Conclusions:It is necessary to obtain not less than 2.0 cm of PM distance in early-stage disease,while PM distance was not associated with long-term survival in later and more aggressive stages of disease because more advanced GC is a systemic disease.Different types of patients should be considered for removal of an individualized PM distance intra-operatively.We developed a universally applicable prediction model for accurately determining the 1-year,3-year and 5-year DFS and OS of GC patients according to their preoperative clinicopathologic characteristics and PM distance. | Jun Luo Yuming Jiang Xinhua Chen Yuehong Chen Jhang Lopsang Gurung Tingyu Mou Liying Zhao Guoqing Lyu Tuanjie Li Guoxin Li Jiang Yu | 2020 | Chinese Journal of Cancer Research2020，32，2： | 8 |
| 15 | The Anti-allergic Activity of Polyphenol Extracted from Five Marine Algae显示文摘Natural polyphenol has been widely believed to be effective in allergy remission. Currently, most of the natural polyphenol products come from terrestrial sources such as tea, grape seeds among others, and few polyphenols have been developed from algae for their anti-allergic activity. The aim of the study was to screen some commercial seaweed for natural extracts with anti-allergic activity. Five algae including Laminaria japonica, Porphyra sp., Spirulina platensis, Chlorella pyrenoidosa and Scytosiphon sp. were extracted with ethanol, and the extracts were evaluated for total polyphenol contents and anti-allergic activity with the hyaluronidase inhibition assay. Results showed that the total polyphenol contents in the ethanol extracts ranged from 1.67% to 8.47%, while the highest was found in the extract from Scytosiphon sp. Hyaluronidase inhibition assay showed that the extracts from Scytosiphon sp. had the lowest IC50, 0.67 mg m L-1, while Chlorella pyrenoidosa extract had the highest IC50, 15.07 mg m L-1. The anti-allergic activity of Scytosiphon sp. extract was even higher than the typical anti-allergic drug Disodium Cromoglycate(DSCG)(IC50 = 1.13 mg m L-1), and was similar with natural polyphenol from Epigallocatechin gallate(EGCG)(IC50 = 0.56 mg m L-1). These results indicated that the ethanol extract of Scytosiphon sp. contains a high concentration of polyphenol with high anti-allergic activity. Potentially Scytosiphon sp. can be developed to a natural anti-allergic compound for allergy remission. | CHEN Yu LIN Hong LI Zhenxing MOU Quangui | 2015 | Journal of Ocean University of China2015，14，4： | 7 |

| 17 | A meta-analysis of Chinese herbal medicines for vascular dementia显示文摘OBJECTIVE: To investigate the efficacy and safety of Chinese herbal medicines in the treatment of patients with vascular dementia. DATA RETRIEVAL: We retrieved publications from Cochrane Library (2004 to July 2011), PubMed (1966 to July 2011), the Chinese Science and Technique Journals Database (1977 to July 2011), the China National Knowledge Infrastructure (1979 to July 2011), Google Scholar (July 2011), and the Chinese Biomedical Database (1977 to July 2011) using the'Chinese medicine OR Chinese herbal medicine' and 'vascular dementia OR mild cognition impair OR multi-infarct dementia OR small-vessel dementia OR strategic infarct dementia OR hypoperfusion dementia OR hemorrhagic dementia OR hereditary vascular dementia'. SELECTION CRITERIA: Randomized controlled trials comparing Chinese herbal medicines with placebo/western medicine in the treatment of patients with vascular dementia were included. Diagnostic standards included Diagnostic and Statistical Manual of Mental Disorders-IV, and National Institute of Neurological Disorders and Stroke and Association Internationale pour la Recherché et l'Enseignement en Neurosciences. Two participants independently conducted literature screening, quality evaluation and data extraction. The quality of each trial was assessed according to the Cochrane Reviewers' Handbook 5.0. MAIN OUTCOME MEASURES: Effective rate, Mini-Mental State Examination scores, Hasegawa Dementia Scale scores, and incidence of adverse reactions. RESULTS: We identified 1 143 articles discussing the effects of Chinese medicine on vascular dementia. Thirty-one of these were included in the analysis. These studies involved a total of 2 868 participants (1 605 patients took Chinese medicine decoctions (treatment group); 1 263 patients took western medicine or placebo). The results of our meta-analysis revealed that Chinese herbal remedies in the treatment group were more efficacious than the control intervention (relative risk (RR)=1.27; 95% confidence interval (CI): 1.18-1.38, P<0.01). Mini-Mental State Examination scores were higher in patients taking Chinese herbal medicines than in those in the control group (weighted mean difference (WMD)=2.83; 95%CI: 2.55-3.12, P<0.01). Patients in the treatment group showed better disease amelioration than those in the control group (Hasegawa Dementia Scale scores; WMD=2.41, 95%CI: 1.48-3.34, P<0.01). There were also considerably fewer adverse reactions among those in the treatment group compared with those in the control group (RR=0.20, 95%CI: 0.08-0.47, P<0.01). CONCLUSION: Chinese herbal medicine appears to be safer and more effective than control measures in the treatment of vascular dementia. However, the included trials were generally low in quality. More well-designed, high-quality trials are needed to provide better evidence for the assessment of the efficacy and safety of Chinese medicines for vascular dementia. | Xiude Qin Yu Liu Yanqing Wu Shuo Wang Dandan Wang Jinqiang Zhu Qiaofeng Ye Wei Mou Liyuan Kang | 2013 | Neural Regeneration Research2013，8，18： | 7 |
