| 1 | Level of circulating PD-L1 expression in patients with advanced gastric cancer and its clinical implications显示文摘Objective:The programmed cell death-1 receptor/programmed cell death-1 ligand(PD-1/PD-L1) pathway plays a crucial role in tumor evasion from host immunity.This study was designed to evaluate the association between circulating PD-L1 expression and prognosis in patients with advanced gastric cancer.Methods:Totally 80 advanced gastric cancer patients and 40 health controls from Beijing Cancer Hospital were enrolled in the present study.Circulating PD-L1 expression was tested by enzymelinked immunosorbent assay(ELISA).The associations between the expression level of PD-L1 and clinicopathological features and prognosis were analyzed statistically.Results:Expression of PD-L1 in advanced gastric cancer patients was significantly up-regulated compared with health people(P=0.006).The expression of PD-L1 was significantly correlated with differentiation and lymph node metastasis(P=0.026 and P=0.041,respectively).Although we didn't find significant difference in all advanced gastric cancer patients with different PD-L1 expression,the adenocarcinoma patients with higher up-regulated PD-L1 expression had much better prognosis than low expression patients(65.6% vs.44.7%,P=0.028).Conclusions:PD-L1 was elevated in advance gastric cancer patients and may play an important role in tumor immune evasion and patients prognosis. | Zhixue Zheng Zhaode Bu Xijuan Liu Lianhai Zhang Ziyu Li Aiwen Wu Xiaojiang Wu Xiaojing Cheng Xiaofang Xing Hong Du Xiaohong Wang Ying Hu Jiafu Ji | 2014 | Chinese Journal of Cancer Research2014，26，1： | 37 |
| 2 | LGR5 is a promising biomarker for patients with stage Ⅰ and Ⅱ gastric cancer显示文摘Objective: To investigate Leucine-rich repeat-containing G protein-coupled receptor 5 (LGR5) expressions in gastric cancer and to evaluate its clinical significance. Methods: LGR5 expression was assessed by immunohistochemistry in 257 gastric cancer patients after surgery. The relationships between LGR5 expression and clinicopathological features and patients prognosis were statistically analyzed. Results: The expression of LGR5 was significantly higher in gastric cancers as a cancer stem cell marker than in adjacent normal tissues (P<0.001), and more frequently in patients with intestinal type, well-moderate differentiation and stage Ⅰ and Ⅱ (P<0.05). Although we found gastric cancer patients with LGR5 positive expression had a poorer prognosis, it didn't meet statistical significance (P>0.05). LGR5 negative expression was significantly related to the favorable overall survival in stage Ⅰ and Ⅱ gastric cancer patients (P<0.05). Furthermore, patients with high LGR5 expression tended to be more likely to get progression and have poorer progress-free survival (P<0.05). Multivariate Cox regression analysis revealed that LGR5 expression was an independent factor of overall survival for the patients with stage Ⅰ and Ⅱ gastric cancer (P<0.05). Conclusions: Our results show that LGR5 may play an important role in tumorigenesis and progression and would be a powerful marker to predict the prognosis of patients with stage Ⅰ and Ⅱ gastric cancer. | Zhaode Bu Zhixue Zheng Lianhai Zhang Ziyu Li Yu Sun Bin Dong Aiwen Wu Xiaojiang Wu Xiaohong Wang Xiaojing Cheng Xiaofang Xing Yingai Li Hong Du Jiafu Ji | 2013 | Chinese Journal of Cancer Research2013，25，1： | 17 |
| 3 | Downstaging and resection of hepatocellular carcinoma in patients with extrahepatic metastases after stereotactic therapy显示文摘Background:A combination of tyrosine kinase inhibitors(TKIs)and anti-PD-1 antibodies with local regional therapy has elicited yield substantial clinical benefits in patients who have hepatocellular carcinoma(HCC)with extrahepatic metastases.Using this treatment strategy to convert HCC patients with extrahepatic metastases from unresectable to resectable has not yet been reported.Methods:Consecutive hepatocellular carcinoma patients with extrahepatic metastases who received first-line therapy with a combination of TKIs and anti-PD-1 antibodies and at least one local regional therapy were analysed.Results:Nine patients with localized disease who received first-line systemic therapy were enrolled.At baseline,all of them had oligometastatic disease,namely,Barcelona Clinic Liver Cancer stage C(or Chinese Liver Cancer stage IIIB).The most common treatment administered was lenvatinib plus anti-PD-1 antibody and transarterial chemoembolization,and the median time span from systemic therapy to surgery was 3.2(IQR,2.8-6.2)months.Three patients achieved a pathological complete response.Six patients underwent laparoscopic surgery,and the other 3 patients underwent open surgery.After a median follow-up of 10.2(IQR,8.6-20.0)months,7 patients survived without disease recurrence,and 2 experienced tumour recurrence.All patients had any-grade AEs,and 55.6%of the patients experienced grade 3 AEs.Fatigue was the most common AE,followed by elevated aminotransferase levels and hypertension.Conclusions:Stereotactic therapy is a feasible conversion therapy for HCC patients with extrahepatic metastases to become resectable.This is the first study to analyse therapeutic outcomes of patients receiving these therapies for HCC with extrahepatic metastases. | Xiaobo Yang Haifeng Xu Bangyou Zuo Xu Yang Jin Bian Junyu Long Dongxu Wang Junwei Zhang Cong Ning Yanyu Wang Ziyu Xun Yunchao Wang Xin Lu Yilei Mao Xinting Sang Haitao Zhao | 2021 | Hepatobiliary Surgery and Nutrition2021，10，4： | 17 |
| 4 | Depth of tumor invasion and tumor-occupied portions of stomach are predictive factors of intra-abdominal metastasis显示文摘Objective:Diagnostic laparoscopy is recommended for the pretherapeutic staging of gastric cancer to detect any unexpected or unconfirmed intra-abdominal metastasis.The aim of this study was to evaluate the role and indications of diagnostic laparoscopy in the detection of intra-abdominal metastasis.Methods:Standard diagnostic laparoscopy with peritoneal cytology examination was performed prospectively on patients who were clinically diagnosed with primary local advanced gastric cancer(c T≥2M0).We calculated the rate of intra-abdominal metastases identified by diagnostic laparoscopy,and examined the relationship between peritoneal dissemination(P)and cytology results(CY).Split-sample method was applied to find clinical risk factors for intra-abdominal metastasis.Multivariate logistic regression analysis and receiver-operator characteristic(ROC)analysis were performed in training set to find out risk factors of intra-abdominal metastasis,and then validate it in testing set.Results:Out of 249 c M0 patients,51(20.5%)patients with intra-abdominal metastasis were identified by diagnostic laparoscopy,including 20(8.0%)P1CY1,17(6.8%)P0CY1 and 14(5.6%)P1CY0 patients.In the training set,multivariate logistic regression analysis and ROC analysis showed that the depth of tumor invasion on computer tomography(CT)scan≥21 mm and tumor-occupied≥2 portions of stomach are predictive factors of metastasis.In the testing set,when diagnostic laparoscopy was performed on patients who had one or two of these risk factors,the sensitivity and positive predictive value for detecting intra-abdominal metastasis were 90.0%and32.1%,respectively.Conclusions:According to our results,depth of tumor invasion and tumor-occupied portions of stomach are predictive factors of intra-abdominal metastasis. | Ziyu Li Zhemin Li Shuqin Jia Zhaode Bu Lianhai Zhang Xiaojiang Wu Shuangxi Li Fei Shan Xin Ji Jiafu Ji | 2017 | Chinese Journal of Cancer Research2017，29，2： | 14 |
| 5 | Construction and external validation of a nomogram that predicts lymph node metastasis in early gastric cancer patients using preoperative parameters显示文摘Objective: To create a nomogram to predict the incidence of lymph node metastasis(LNM) in early gastric cancer(EGC) patients and to externally validate the nomogram.Methods: To construct the nomogram,we retrospectively analyzed a primary cohort of 272 EGC patients.Univariate analysis and a binary logistic regression were performed.A nomogram predicting the incidence of LNM in EGC patients was created.The discrimination ability of the nomogram was measured using the concordance index(c-index),and the nomogram was also calibrated.Then,another prospective cohort of 81 patients was analyzed to validate the nomogram.Results: In the primary cohort,LNM was pathologically confirmed in 37(13.6%) patients.In multivariate analysis,the presence of an ulcer,the maximum lesion diameter observed via gastroscopy,the thickness of the lesion observed via endoscopic ultrasonography,and the presence of enlarged lymph nodes on computed tomography(CT) were independent risk factors for LNM.A nomogram was then created based on the regression model with the c-index of 0.905,and the calibration curve of the nomogram fell approximately on the ideal 45-degree line.The cut-off score of the nomogram was 110,and the sensitivity,specificity,positive predictive and negative predictive values of the nomogram in the primary cohort were 81.1%,86.0%,47.6% and 96.7%,respectively,and in the prospective validation cohort were 75.0%,91.0%,60.0% and 95.5%,respectively.The calibration curve of the external validation cohort was almost on the 45-degree line.Conclusions: We developed an effective nomogram predicting the incidence of LNM for EGC patients. | Yinan Zhang Yiqiang Liu Ji Zhang Xiaojiang Wu Xin Ji Tao Fu Ziyu Li Qi Wu Zhaode Bu Jiafu Ji | 2018 | Chinese Journal of Cancer Research2018，30，6： | 12 |
| 6 | Dietary protocatechuic acid ameliorates inflammation and up-regulates intestinal tight junction proteins by modulating gut microbiota in LPS-challenged piglets显示文摘Background: Weaning is one of the major factors that cause stress and intestinal disease in piglets. Protocatechuic acid(PCA) is an active plant phenolic acid which exists in Chinese herb, Duzhong(Eucommia ulmoides Oliver), and is also considered as the main bioactive metabolite of polyphenol against oxidative stress and inflammation. This study aimed to investigate the effect of PCA on growth performance, intestinal barrier function, and gut microbiota in a weaned piglet model challenged with lipopolysaccharide(LPS).Methods: Thirty-six piglets(Pig Improvement Company line 337 × C48, 28 d of age, 8.87 kg ± 0.11 kg BW) were randomly allocated into 3 treatments and fed with a basal diet(CTL), a diet added 50 mg/kg of aureomycin(AUR), or a diet supplemented with 4000 mg/kg of PCA, respectively. The piglets were challenged with LPS(10 μg/kg BW) on d 14 and d 21 by intraperitoneal injection during the 21-d experiment. Animals(n = 6 from each group) were sacrificed after being anesthetized by sodium pentobarbital at 2 h after the last injection of LPS. The serum was collected for antioxidant indices and inflammatory cytokines analysis, the ileum was harvested for detecting mRNA and protein levels of tight junction proteins by PCR and immunohistochemical staining, and the cecum chyme was collected for intestinal flora analysis using 16 S rRNA gene sequencing.Results: Dietary supplementation of PCA or AUR significantly increased the expression of tight junction proteins including ZO-1 and claudin-1 in intestinal mucosa, and decreased the serum levels of thiobarbituric acid reactive substances(TBARS) and IL-6, as compared with CTL group. In addition, PCA also decreased the serum levels of IL-2 and TNF-α(P < 0.05). Analysis of gut microbiota indicated that PCA increased the Firmicutes/Bacteroidetes ratio(P < 0.05). Spearman's correlation analysis at the genus level revealed that PCA reduced the relative abundance of Prevotella 9, Prevotella 2, Holdemanella, and Ruminococcus torques group(P < 0.05), and increased the relative abundance of Roseburia and Desulfovibrio(P < 0.05), whereas AUR had no significant effect on these bacteria.Conclusions: These results demonstrated that both PCA and AUR had protective effect on oxidative stress, inflammation and intestinal barrier function in piglets challenged with LPS, and PCA potentially exerted the protective function by modulating intestinal flora in a way different from AUR. | Ruizhi Hu Ziyu He Ming Liu Jijun Tan Hongfu Zhang De-Xing Hou Jianhua He Shusong Wu | 2021 | Journal of Animal Science and Biotechnology2021，12，1： | 12 |
| 7 | Prognostic role of lymph node metastasis in early gastric cancer显示文摘Objective: To clarify the relationship between clinicopathological features and lymph node metastasis and to propose the potential indications of lymph node metastasis for prognosis in early gastric cancer(EGC) patients. Methods: We retrospectively observed 226 EGC patients with lymph node resection, and analyzed the associations between lymph node metastasis and clinicopathological parameters using the chi-square test in univariate analysis and logistic regression analysis in multivariate analysis. Overall survival analysis was determined using the Kaplan-Meier and log-rank test. We conducted multivariate prognosis analysis using the Cox proportional hazards model.Results: Of all the EGC patients, 7.5%(17/226) were histologically shown to have lymph node metastasis. The differentiation, lymphovascular invasion and depth of invasion were independent risk factors for lymph node metastasis in EGC. The 5- and 10-year survival rates were significantly lower in patients with lymph node metastasis than in those without and the patients also had shorter progress-free survival time. Lymph node metastasis and tumor size were independent prognostic factors for EGC. The status of the lymph nodes was a significant factor in predicting recurrence or metastasis after surgery. Conclusions: The undifferentiated carcinoma and lymphovascular and/or submucosal invasion were associated with a higher incidence of lymph node metastasis in EGC patients, whom need to perform subsequent D2 lymphadenectomy or laparoscopic lymph node dissection and more rigorous follow-up or additional chemotherapy/radiation after D2 gastrectomy for poor prognosis and high recurrence/metastasis rate. | Zhixue Zheng Yiqiang Liu Zhaode Bu Lianhai Zhang Ziyu Li Hong Du Jiafu Ji | 2014 | Chinese Journal of Cancer Research2014，26，2： | 12 |
| 8 | Oxaliplatin plus S-1 or capecitabine as neoadjuvant or adjuvant chemotherapy for locally advanced gastric cancer with D2lymphadenectomy: 5-year follow-up results of a phase II-III randomized trial显示文摘Objective: To compare the effect of neoadjuvant chemotherapy(NACT) with adjuvant chemotherapy(ACT)using oxaliplatin plus S-1(SOX) or capecitabine(CapeOX) on gastric cancer patients with D2 lymphadenectomy.Methods: This was a two-by-two factorial randomized phase II-III trial, and registered on ISRCTN registry(No. ISRCTN12206108). Locally advanced gastric cancer patients were randomized to neoadjuvant SOX,neoadjuvant CapeOX, adjuvant SOX, or adjuvant CapeOX arms. Primary analysis was performed on an intentionto-treat(ITT) basis using overall survival(OS) as primary endpoint.Results: This trial started in September 2011 and closed in December 2012 with 100 patients enrolled.Treatment completion rate was 56%, 52%, 38% and 30% in the four arms, respectively. NACT group had fewer dropouts due to unacceptable toxicity(P=0.042). Surgical complication rate did not differ by the four groups(P=0.986). No survival significant difference was found comparing NACT with ACT(P=0.664; 5-year-OS: 70% vs.74% respectively), nor between the SOX and CapeOX groups(P=0.252; 5-year-OS: 78% vs. 66% respectively).Subgroup analysis showed SOX significantly improved survival in patients with diffuse type(P=0.048).Conclusions: No significant survival difference was found between NACT and ACT. SOX and CapeOX had good safety and efficacy as neoadjuvant regimens. Diffuse type patients may survive longer due to SOX. | Kan Xue Xiangji Ying Zhaode Bu Aiwen Wu Zhongwu Li Lei Tang Lianhai Zhang Yan Zhang Ziyu Li Jiafu Ji | 2018 | Chinese Journal of Cancer Research2018，30，5： | 10 |
| 9 | Diffraction-limited imaging with monolayer 2D material-based ultrathin flat lenses显示文摘Ultrathin flat optics allow control of light at the subwavelength scale that is unmatched by traditional refractive optics.To approach the atomically thin limit,the use of 2D materials is an attractive possibility due to their high refractive indices.However,achievement of diffraction-limited focusing and imaging is challenged by their thickness-limited spatial resolution and focusing efficiency.Here we report a universal method to transform 2D monolayers into ultrathin flat lenses.Femtosecond laser direct writing was applied to generate local scattering media inside a monolayer,which overcomes the longstanding challenge of obtaining sufficient phase or amplitude modulation in atomically thin 2D materials.We achieved highly efficient 3D focusing with subwavelength resolution and diffractionlimited imaging.The high focusing performance even allows diffraction-limited imaging at different focal positions with varying magnifications.Our work paves the way for downscaling of optical devices using 2D materials and reports an unprecedented approach for fabricating ultrathin imaging devices. | Han Lin Zai-Quan Xu Guiyuan Cao Yupeng Zhang Jiadong Zhou Ziyu Wang Zhichen Wan Zheng Liu Kian Ping Loh Cheng-Wei Qiu Qiaoliang Bao Baohua Jia | 2020 | Light(Science & Applications)2020，9，1： | 9 |
| 10 | Diode-pumped power scalable Kerr-lens mode-locked Yb:CYA laser显示文摘Stable 68 fs pulses with the average power of 1.5 W is directly generated from a multimode diode-pumped Kerr-lens mode-locked Yb:CYA laser by separating the gain medium and Kerr medium. The repetition rate is about 50 MHz, resulting in a single pulse energy of 30 n J and a peak power of 0.44 MW. To the best of our knowledge, this is the highest single pulse energy ever produced from a mode-locked Yb:CYA oscillator. Our experimental results show that Yb:CYA crystal is an excellent candidate for multiwatt, sub-100 fs pulse generation in diode-pumped all-solid-state lasers. It is believed that the output power can be scalable to multi-W while the pulse duration is maintained with this simple method. | WENLONG TIAN YINGNAN PENG ZIYUE ZHANG ZIJIAO YU JIANGFENG ZHU XIAODONG XU ZHIYI WEI | 2018 | Photonics Research2018，6，2： | 8 |
| 11 | Gut microbiota-derived short chain fatty acids are potential mediators in gut inflammation显示文摘Gut inflammation is a challenging concern in humans and animals,which disturbs normal growth and leads to severe bowel diseases.Short chain fatty acids(SCFA)are the gut microbiota metabolites produced from fermentation of non-digestible carbohydrates,and have been reported to modulate gut inflammation.SCFA have been implicated as the potential therapeutic bioactive molecules for gut inflammatory diseases,and could be an alternative to antibiotic growth promoters(AGP).In this review,the existing knowledge about the types of SCFA,the related gut microbes producing SCFA,the roles of SCFA in maintaining gut homeostasis,and how SCFA modulate gut inflammation is summarized.The therapeutic application of SCFA in the treatment of inflammatory bowel disease(IBD)is also highlighted | Muhammad Akhtar Yan Chen Ziyu Ma Xiaolong Zhang Deshi Shi Jawaria AKhan Huazhen Liu | 2022 | Animal Nutrition2022，，1： | 8 |
| 12 | Durability of neutralizing antibodies and T-cell response post SARS-CoV-2 infection显示文摘The ongoing pandemic of coronavirus disease 19(COVID-19)is caused by a newly discoveredβcoronavirus named severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).How long the adaptive immunity triggered by SARS-CoV-2 can last is of critical clinical relevance in assessing the probability of second infection and efficacy of vaccination.Here we examined,using ELISA,the IgG antibodies in serum specimens collected from 17 COVID-19 patients at 6–7 months after diagnosis and the results were compared to those from cases investigated 2 weeks to 2 months post-infection.All samples were positive for IgGs against the S-and N-proteins of SARS-CoV-2.Notably,14 samples available at 6–7 months post-infection all showed significant neutralizing activities in a pseudovirus assay,with no difference in blocking the cell-entry of the 614D and 614G variants of SARS-CoV-2.Furthermore,in 10 blood samples from cases at 6–7 months post-infection used for memory T-cell tests,we found that interferonγ-producing CD4+and CD8+cells were increased upon SARS-CoV-2 antigen stimulation.Together,these results indicate that durable anti-SARS-CoV-2 immunity is common in convalescent population,and vaccines developed from 614D variant may offer protection from the currently predominant 614D variant of SARS-CoV-2. | Yun Tan Feng Liu Xiaoguang Xu Yun Ling Weijin Huang Zhaoqin Zhu Mingquan Guo Yixiao Lin Ziyu Fu Dongguo Liang Tengfei Zhang Jian Fan Miao Xu Hongzhou Lu Saijuan Chen | 2020 | Frontiers of Medicine2020，14，6： | 6 |
| 13 | Uniform corrosion behavior of FeCrAl alloys in borated and lithiated high temperature water显示文摘The uniform corrosion behavior of model FeCrAl alloys as well as commercial Zircaloy-4 as reference material were investigated in 360℃borated and lithiated water.The results reveal that FeCrAl alloys exhibited better corrosion resistance than Zircaloy-4.It is found that the oxide films formed on the FeCrAl alloys are composed of outer Fe_(3)O_(4)layer,inner layer consisting of compact spinel layer and porous spinel layer,and transition layer containing Al-Cr-rich oxides and matrix enriched with Fe°.The spinel oxides in the inner layer are FeFe_(2-x-y-z)Cr_(x)Al_(y)MozO_(4).The corrosion mechanism of FeCrAl alloys in high temperature water is discussed. | Fangqiang Ning Xiang Wang Ying Yang Jibo Tan Ziyu Zhang Dan Jia Xinqiang Wu En-Hou Han | 2021 | Journal of Materials Science & Technology2021，，11： | 6 |
| 14 | Sulfur-containing compounds as electrolyte additives for lithium-ion batteries显示文摘Originating from“rocking-chair concept”,lithium-ion batteries(LIBs)have become one of the most important electrochemical energy storage technolo-gies,which have largely impacted our daily life.The utilization of electrolyte additives in small quantities(≤5%by wt or vol)has been long viewed as an economical and efficient approach to regulate the properties of electrolyte and electrode–electrolyte interphases and consequently improve the cycling perfor-mance of LIBs.Among all the kinds of electrolyte additives,sulfur-containing compounds have gained significant attention due to their unique features in building stable electrode–electrolyte interphases and protect battery cells from overcharging.In this work,advances and progresses of sulfur-containing addi-tives used in LIBs are overviewed,with special attention paid to the working mechanisms of these electrolyte additives.Particularly,four representative sulfur-containing compounds(i.e.,1,3-propane sultone,prop-1-ene-1,3-sultone,1,3,2-dioxathiolane-2,2-dioxide,and ethylene sulfite)are comparatively dis-cussed concerning their impact on electrode–electrolyte interphases and cell per-formances.Future work on the development of sulfur-containing compounds as functional electrolyte additives is also provided.The present review is antici-pated to be not only a base document to access the status quo in this research domain but also a guideline to select specialized additives and electrolytes for practical applications. | Bo Tong Ziyu Song Huihai Wan Wenfang Feng Michel Armand Jincheng Liu Heng Zhang Zhibin Zhou | 2021 | InfoMat2021，3，12： | 6 |
| 15 | Anatomical variation of infra-pyloric artery origination: A prospective multicenter observational study (IPA-Origin)显示文摘Objective: Infra-pyloric artery(IPA) is an important anatomical landmark in treatment of gastric cancer and is the key vessel for pylorus-preserving gastrectomy and subgroup of infra-pyloric lymph nodes. However, its anatomical variation is not thoroughly understood. Our study aimed to clarify the origination of the IPA.Methods: We did this prospective, multicenter, open-label, observational study at gastric surgery departments of34 hospitals in China. Gastric cancer patients aged 18 years or older and scheduled to undergo elective total or distal gastrectomy were assigned. During the surgery, IPA dissecting and exposing the origination point with photographs or video clips were required. The primary outcome was the origination of the IPA. Analysis of variance, χ~2 tests and Fisher's tests were used to analyze the differences between groups. The study is registered at Clinicaltrials.gov(No. NCT03071237).Results: Between May 8 and July 31, 2017, 429 patients were assigned for the study, and 419(97.7%) patients had the IPA dissected and recorded through photograph or video and were included in the primary outcome analysis. The median age was 62 years old, and 73.7% were male. Among the patients, 78.5% received laparoscopic surgery. Single IPA origination was identified in 398(95.0%) patients, including gastroduodenal artery(GDA) in154(36.8%) patients, anterior superior pancreaticoduodenal artery(ASPDA) in 130(31.0%) patients, and right gastroepiploic artery(RGEA) in 114(27.2%) patients. Fifteen(3.6%) patients were identified with multiple IPA and 6(1.4%) patients were identified as IPA absence. The differences in the distribution of surgical approach(P=0.003) and geographic area(P=0.030) were statistically significant. No difference was shown in sex, age,gastrectomy type, tumor location, and clinical T, N and M stage.Conclusions: Our study found that the IPA originates from GDA, ASPDA and RGEA in similar proportions.Laparoscopic surgery may be more helpful in dissection of the IPA than open surgery. | Rulin Miao Jianjun Qu Zhengrong Li Daguang Wang Jiang Yu Weidong Zang Yong Li Fenglin Liu Jian Zhang Wu Song Kai Ye Su Yan Wei Wang Shuangyi Ren Lu Zang Changqing Jing Li Zhang Kuan Wang Weihua Fu Lin Fan Bin Liang Gang Zhao Jun Cai Li Yang Jiaming Zhu Jun You Kun Yang Qingxing Huang Zhaojian Niu Ning Ning Xingfeng Qiu Gang Ji Feng Liang Hua Huang Chao Gao Fei Shan Shuangxi Li Yongning Jia Lianhai Zhang Xiangji Ying Yan Zhang Zhaode Bu Xiangqian Su Gang Zhao Ziyu Li Jiafu Ji | 2018 | Chinese Journal of Cancer Research2018，30，5： | 5 |

| 17 | The five major autoimmune diseases increase the risk of cancer:epidemiological data froma large-scale cohort study in China显示文摘Background:Cancer incidence and mortality have received critical attention during the long-term management of morbidities in patients with autoimmune diseases(AIDs).This study aimed to investigate and compare the risk of cancer associated with five major AIDs in a large-scale Chinese cohort.Methods:A total of 8,120 AID patients consecutively admitted to a national tertiary referral center in China were included and followed-up for 38,726.55 patient-years,including those with systemic lupus erythematosus(SLE),rheumatoid arthritis(RA),Sjoren’s syndrome(SS),systemic scleroderma(SSc),and idiopathic inflammatory myositis(IIM).Demographic data,cancer incidence,predilecting sites and cancer onset time were recorded and compared among the five AIDs.Results:Four hundred and thirty(5.3%)patients developed cancer.Their median agewas 57.5 years and AID durationwas 79.8 months.The estimated total standardized incidence ratio(SIR)of cancer in AIDs patients was 3.37,with the highest SIR observed in IIM(4.31),followed by RA(3.99),SSc(3.77),SS(2.88)and SLE(2.58).The increased SIR of cancers in AID patients showed a female predominance(female vs.male:3.59 vs.2.77)and younger patient involvement(age<50 vs.≥50 years:4.88 vs.3.04).Patientswith SLE had increased SIRs for developing hematologic malignancies and solid tumors located in the urinary bladder,corpus uteri and cervix uteri.Patients with SS had a significantly high SIR for developing non-Hodgkin’s lymphoma.Within 3 years of IIM diagnosis,74.6%of the patients developed cancer and they had a high risk of ovarian cancer.RA was associated with a wide distribution of scancers,including non-Hodgkin’s lymphoma,gynecologic,urinary tract,thyroid gland and lung cancers.SSc patients had increased SIRs for developing cervical uterine,lung,and breast cancers.Conclusion:Patients with five major AIDs in China had an increased risk of developing cancer,with a predominance in women and younger patients,although cancer incidence,predilection sites and cancer onset time may vary greatly in each AID entity. | Ziyue Zhou Huazhen Liu Yiying Yang Jingya Zhou Lidan Zhao Hua Chen Yunyun Fei Wen Zhang Mengtao Li Yan Zhao Xiaofeng Zeng Fengchun Zhang Huaxia Yang Xuan Zhang | 2022 | Cancer Communications2022，42，5： | 4 |
| 18 | Germline mutations in hereditary diffuse gastric cancer显示文摘Gastric cancer is one of the leading causes of cancer-related deaths worldwide. Among which, about 1%–3% of gastric cancer patients were characterized by inherited gastric cancer predisposition syndromes, knowing as hereditary diffuse gastric cancer(HDGC). Studies reported that CDH1 germline mutations are the main cause of HDGC. With the help of rapid development of genetic testing technologies and data analysis tools, more and more researchers focus on seeking candidate susceptibility genes for hereditary cancer syndromes. In addition, National Comprehensive Cancer Network(NCCN) guidelines recommend that the patients of HDGC carrying CDH1 mutations should undergo prophylactic gastrectomy or routine endoscopic surveillances. Therefore, genetic counseling plays a key role in helping individuals with pathogenic mutations make appropriate risk management plans. Moreover, experienced and professional genetic counselors as well as a systematic multidisciplinary team(MDT) are also required to facilitate the development of genetic counseling and benefit pathogenic mutation carriers who are in need of regular and standardized risk management solutions. In this review, we provided an overview about the germline mutations of several genes identified in HDGC, suggesting that these genes may potentially act as susceptibility genes for this malignant cancer syndrome. Furthermore, we introduced information for prevention, diagnosis and risk management of HDGC. Investigations on key factors that may have effect on risk management decision-making and genetic data collection of more cancer syndrome family pedigrees are required for the development of HDGC therapeutic strategies. | Hao Zhang Mengmeng Feng Yi Feng Zhaode Bu Ziyu Li Shuqin Jia Jiafu Ji | 2018 | Chinese Journal of Cancer Research2018，30，1： | 4 |
| 19 | A 70 Gbps NRZ optical link based on 850 nm band-limited VCSEL for data-center intra-connects显示文摘Short-reach optical interconnects among servers in data centers have attracted extensive studies recently. High capacity and low cost are two key problems for optical link. In this paper, we demonstrate a band-limited 850 nm vertical cavity surface emitting laser(VCSEL) based optical transmission system. The optical link realizes 70 Gb/s(65 Gb/s net rate) non-return-to-zero(NRZ) signal transmission over 11 m and20 m OM4 multimode fiber(MMF), with the help of equalization for time domain interference elimination.The utilized VCSEL has a bandwidth of only 18 GHz, meeting the principle of low cost. The data baud rate in this paper reaches the highest value for an 18-GHz-class 850 nm VCSEL based optical link, to our best knowledge. | Zhongwei TAN Chuanchuan YANG Yixiao ZHU Zhaopeng XU Kaiheng ZOU Fan ZHANG Ziyu WANG | 2018 | Science China(Information Sciences)2018，61，8： | 3 |
| 20 | Clinicopathological and prognostic differences between mucinous gastric carcinoma and signet-ring cell carcinoma显示文摘Objective: To analyze the differences in clinicopathologic characteristics and prognosis between mucinous gastric carcinoma (MGC) and signet-ring cell carcinoma (SRCC). Methods: Clinicopathologic and prognostic data of 1,637 patients with histologically confirmed MGC or SRCC who received surgical operations in the Department of Gastroenterological Surgery, Beijing Cancer Hospital between December 2004 and December 2009 were retrospectively collected and analyzed. The clinicopathological features were analyzed statistically using χ 2 test. Survival was analyzed using the Kaplan-Meier method and multivariate analysis of Cox proportional hazards regression model (backward, stepwise). Results: A total of 181 patients with gastric cancer (74 MGC, 107 SRCC) were included. MGC, when compared with SRCC, was featured by senile patients, stage III and IV, upper third stomach, large tumor size, positive lymph node metastasis, and positive lymphatic vascular invasion (P<0.05). The overall 5-year survival rate showed no difference between the two groups (48.8% vs. 44.8%, P>0.05). However, the survival rate for MGC patients was significant lower than that for SRCC patients when compared among the age <60 years, negative distant metastasis, and tumor localized at upper third stomach (P<0.05). Multivariate Cox proportional hazards models revealed that distant metastasis was a significant independent prognostic indicator in MGC group, and lymph node metastasis and distant metastasis was significant independent prognostic indicators in SRCC group. Conclusions: While compared with SRCC, MGC is associated with a more aggressive tumor biologic behavior. There is no statistically significant difference in distant metastasis, an independent prognostic indicator for both MGC and SRCC, which might be the reason for no significant difference of the overall survival rate between the patients with MGC and SRCC. | Zhaode Bu Zhixue Zheng Ziyu Li Xiaojiang Wu Lianhai Zhang Aiwen Wu Xianglong Zong Jiafu Ji | 2013 | Chinese Journal of Cancer Research2013，25，1： | 3 |
