| 1 | Practice guidelines for the pathological diagnosis of primary liver cancer: 2015 update显示文摘In 2010, a panel of Chinese pathologists reported the first expert consensus for the pathological diagnosis of primary liver cancers to address the many contradictions and inconsistencies in the pathological characteristics and diagnostic criteria for PLC. Since then considerable clinicopathological studies have been conducted globally, prompting us to update the practice guidelines for the pathological diagnosis of PLC. In April 18, 2014, a Guideline Committee consisting of 40 specialists from seven Chinese Societies(including Chinese Society of Liver Cancer, Chinese Anti-Cancer Association; Liver Cancer Study Group, Chinese Society of Hepatology, Chinese Medical Association; Chinese Society of Pathology, Chinese Anti-Cancer Association; Digestive Disease Group, Chinese Society of Pathology, Chinese Medical Association; Chinese Society of Surgery, Chinese Medical Association; Chinese Society of Clinical Oncology, Chinese Anti-Cancer Association; Pathological Group of Hepatobiliary Tumor and Liver Transplantation, Chinese Society of Pathology, Chinese Medical Association) was created for the formulation of the first guidelines for the standardization of the pathological diagnosis of PLC, mainly focusing on the following topics: gross specimen sampling, concepts and diagnostic criteria of small hepatocellular carcinoma(SHCC), microvascular invasion(MVI), satellite nodules,and immunohistochemical and molecular diagnosis. The present updated guidelines are reflective of current clinicopathological studies, and include a novel 7-point baseline sampling protocol, which stipulate that at least four tissue specimens should be sampled at the junction of the tumor and adjacent liver tissues in a 1:1 ratio at the 12, 3, 6 and 9 o'clock reference positions. For the purposes of molecular pathological examination, at least one specimen should be sampled at the intratumoral zone, but more specimens should be sampled for tumors harboring different textures or colors. Specimens should be sampled at both adjacent and distant peritumoral liver tissues or the tumor margin in order to observe MVI, satellite nodules and dysplastic foci/nodules distributed throughout the background liver tissues. Complete sampling of whole SHCC ≤ 3 cm should be performed to assess its biological behavior, and in clinical practice, therapeutic borders should be also preserved, even in SHCC. The diagnostic criteria of MVI and satellite nodules, immunohistochemical panels, as well as molecular diagnostic principles, such as clonal typing, for recurrent HCC and multinodule HCC were also proposed and recommended. The standardized process of pathological examination is aimed at ensuring the accuracy of pathological PLC diagnoses as well as providing a valuable frame of reference for the clinical assessment of tumor invasive potential, the risk of postoperative recurrence, long-term survival, and the development of individualized treatment regimens. The updated guidelines could ensure the accuracy of pathological diagnoses of PLC, and provide a valuable frame of reference for its clinical assessment. | Wen-Ming Cong Hong Bu Jie Chen Hui Dong Yu-Yao Zhu Long-Hai Feng Jun Chen 无 | 2016 | World Journal of Gastroenterology2016,22,42: | 81 |
| 2 | Emergence and prevalence of naturally occurring lower virulent African swine fever viruses in domestic pigs in China in 2020显示文摘African swine fever virus(ASFV)has been circulating in China for more than two years,and it is not clear whether the biological properties of the virus have changed.Here,we report on our surveillance of ASFVs in seven provinces of China,from June to December,2020.A total of 22 viruses were isolated and characterized as genotype II ASFVs,with mutations,deletions,insertions,or short-fragment replacement occurring in all isolates compared with Pig/HLJ/2018(HLJ/18),the earliest isolate in China.Eleven isolates had four different types of natural mutations or deletion in the EP402R gene and displayed a nonhemadsorbing(non-HAD)phenotype.Four isolates were tested for virulence in pigs;two were found to be as highly lethal as HLJ/18.However,two non-HAD isolates showed lower virulence but were highly transmissible;infection with 106 TCID50 dose was partially lethal and caused acute or sub-acute disease,whereas 103 TCID50 dose caused non-lethal,sub-acute or chronic disease,and persistent infection.The emergence of lower virulent natural mutants brings greater difficulty to the early diagnosis of ASF and creates new challenges for ASFV control. | Encheng Sun Zhenjiang Zhang Zilong Wang Xijun He Xianfeng Zhang Lulu Wang Wenqing Wang Lianyu Huang Fei Xi Haoyue Huangfu Ghebremedhin Tsegay Hong Huo Jianhong Sun Zhijun Tian Wei Xia Xuewu Yu Fang Li Renqiang Liu Yuntao Guan Dongming Zhao Zhigao Bu | 2021 | Science China(Life Sciences)2021,64,5: | 46 |
| 3 | 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 |

| 5 | 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 |
| 6 | Infantile hepatic hemangioendothelioma:A clinicopathologic study in a Chinese population显示文摘AIM:To investigate whether the clinicopathologic features of infantile hemangioendothelioma(IHE) of the liver in a Chinese population are similar to the features observed in other races.METHODS:The clinical data,radiological findings,histopathological changes and outcome of 12 cases of IHE diagnosed by the Department of Pathology,West China Hospital over the last 10 years were analyzed retrospectively.Immunohistochemical studies were carried out using antibodies against CD31,CD34,Factor Ⅷ,cytokeratin 8 and cytokeratin 18.RESULTS:The 12 patients were aged from fetal to 5 years(three males and nine females).The tumor was presented with different clinical manifestations,mainly as an asymptomatic,palpable,upper abdominal mass,except for the two fetuses who were detected antena-tally by ultrasound.In one patient,this presentation was accompanied by an initial severe pneumothorax.No symptoms of congestive heart failure were present and neither congenital abnormalities nor vascular tumors in the skin or other organs were found.Laboratory abnormalities included leukocytosis(40%),anemia(60%),thrombocytosis(60%),hyperbilirubinemia(16.7%),abnormal liver function(50%) and increased α-fetoprotein(80%).Based on radiological findings and gross specimens,the tumor presented as a solitary lesion or a multifocal space-occupying lesion.The tumor size ranged from 5.0 cm × 3.5 cm × 2.0 cm to 13.8 cm × 9.0 cm × 7.7 cm,and the 0.2-1.1 cm nodules were diffusely distributed within the multifocal tumor.Seven cases were surgically resected,three cases underwent biopsy and the two fetuses were aborted.Histologically,nine cases were classified as typeⅠ and three as type Ⅱ,presenting aggressive morphologic features,immature vessels,active mitosis and necrosis.An inflammatory component,predominantly eosinophilic granulocytes,sometimes obscured the nature of the tumor.Ten patients are alive after a follow-up of 1-9 years.Based on immunohistochemistry,the endothelial cells in all cases were positive for CD31,CD34 and polyclonal factor Ⅷ antigen,whereas the scattered hyperplasia bile ducts were positive for cytokeratin 8 and cytokeratin 18.CONCLUSION:The clinical manifestations of IHE are non-specific.There is no significant correlation between histological type and prognosis.The clinicopathologic features of IHE in Chinese patients may provide a clue to further evidence-based studies. | Zhang Zhang,Hui-Jiao Chen,Wen-Juan Yang,Hong Bu,Bing Wei,Xiao-Yu Long,Jing Fu,Rui Zhang,Yun-Bi Ni,Hong-Ying Zhang,Department of Pathology,West China Hospital,Sichuan University,Guoxuexiang 37,Chengdu 610041,Sichuan Province,China | 2010 | World Journal of Gastroenterology2010,16,36: | 16 |

| 8 | 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 |

| 11 | Clinicopathological, immunohistochemical, and ultrastructural study of 13 cases of melanotic schwannoma显示文摘Background Melanotic schwannoma is a rare variant of schwannoma composed of melanin-producing cellswith ultrastructural features of schwann cells.The description of the course of the tumors differs somewhat, but itis generally considered as a benign lesion.We investigated the clinicopathologic features, immunophenotypes,and ultrastructural features of 13 patients with nonpsammomatous melanotic schwannoma (NPMS).Methods Tumor specimens of each patient were sectioned and stained with hematoxylin-eosin, Fontana-Masson, Prussian blue, and periodic acid-Schiff (PAS).Immunohistochemical markers such as S-100, Leu-7,HMB-45, Melan-A, CK, EMA, vimentin, GFAP, laminin, collagenⅣ and MIB-1 were detected with theEnvision immunohistochemical staining method.Four of the cases were observed by electron microscopy.Results Of the 13 patients, 8 were male and 5 female, aged from 11 to 92 years (mean, 38.6 years).Thetumor sites included the spinal nerve root (5 patients), cranial nerve (1), greater omentum (1), subcutaneoustissue (3), mesentery (1), bone (1) and mediastinum(1).Eleven patients were followed up for over2 years,with a mean of 5.9 years.One patient (9.1%) with a primary tumor in the greater omentum developed anotherprimary tumor of the same type in the subcutaneous tissue of the abdominal wall after the first operation.Localrecurrence of the tumor was seen in2 patients (18.2%).One patient (9.1%) showed the local recurrence andmetastasis.Seven patients (63.6%) showed no evidence of the recurrence or metastasis.Grossly, all tumorswere well-circumscribed and the gross findings were suggestive of melanin-containing tumors.The tumor wascomposed of spindled and epithelioid cells with abundant intracytoplasmic melanin pigments.Nuclei were roundand contained delicate, evenly distributed chromatins as well as small, distinct nucleoli.In some areas, thenucleoli were large and prominent.Rare mitoses were seen in mostlesions exceptthe larger omentumlesion.Thepigment was shown to be positive for the Fontana-Masson and negative for Prussian blue and PAS.Immunohistochemical staining for S-100, Leu-7, HMB-45, Melan-A, and vimentin were strongly positive.Linear immunoreactions of both laminin and collagenⅣ was detected in all patients.Ultrastructurally, numerouselongated tumor-cell processes, duplicated basement membrane and melanosomes were observed in alldevelopmental stages.Conclusions Histologically, melanotic schwannoma is a rare variant of schwannoma composed of melanin-producing cells with ultrastructural features ofschwann cells.Distinguishing between this tumor andmalignant melanoma is of paramount importance inplanning of management. Immunohistochemically,combined use of laminin and collagenⅣ is valuablein distinguishing melanotic schwannoma frommalignant melanoma. Wide local resection andadditional radiotherapy should be advocated.Furtherstudies including cytogenetic or molecular biology arestill required to better delineate melanoticschwannoma from malignant melanoma. Appropriate long-term follow-up is needed for all melanoticschwannomas. | ZHANG Hong-ying YANG Guang-hua CHEN Hui-jiao WEI Bing KE Qi GUO Hua YE Lü BU Hong YANG Ke ZHANG Yuan-heng | 2005 | Chinese Medical Journal2005,,17: | 9 |
| 12 | Chemical Mechanical Polishing of Glass Substrate with α-Alumina-g-Polystyrene Sulfonic Acid Composite Abrasive显示文摘Abrasive is the one of key influencing factors during chemical mechanical polishing(CMP) process. Currently, α-Alumina (α-Al2O3) particle, as a kind of abrasive, has been widely used in CMP slurries, but their high hardness and poor dispersion stability often lead to more surface defects. After being polished with composite particles, the surface defects of work pieces decrease obviously. So the composite particles as abrasives in slurry have been paid more attention. In order to reduce defect caused by pure α-Al2O3 abrasive, α-alumina-g-polystyrene sulfonic acid (α-Al2O3-g-PSS) composite abrasive was prepared by surface graft polymerization. The composition, structure and morphology of the product were characterized by Fourier transform infrared spectroscopy(FTIR), X-ray photoelectron spectroscopy(XPS), time-of-flight secondary ion mass spectroscopy(TOF-SIMS), and scanning electron microscopy(SEM), respectively. The results show that polystyrene sulfonic acid grafts onto α-Al2O3, and has well dispersibility. Then, the chemical mechanical polishing performances of the composite abrasive on glass substrate were investigated with a SPEEDFAM-16B-4M CMP machine. Atomic force microscopy(AFM) images indicate that the average roughness of the polished glass substrate surface can be decreased from 0.835 nm for pure α-Al2O3 abrasive to 0.583 nm for prepared α-Al2O3-g-PSS core-shell abrasive. The research provides a new and effect way to improve the surface qualities during CMP. | LEI Hong BU Naijing ZHANG Zefang CHEN Ruling | 2010 | Chinese Journal of Mechanical Engineering2010,23,3: | 9 |

| 17 | Effects of substitution of Nd in a sand-cast Mg-2.5Nd-0.6Zn-0.5Zr alloy with x wt.% Sm(x=2.5, 4, and 6)显示文摘The microstructures and mechanical properties of a series of sand-cast Mg-Sm-Zn-Zr alloys under ascast, solution-treated and peak-aged states were thoroughly investigated. The OM, XRD, SEM and HRTEM were employed to characterize the microstructural evolution. The results indicate that substitution Nd in the conventional Mg-2.5 Nd-0.6 Zn-0.5 Zr alloy with different contents of Sm has comparative grain refinement effect and will fully change the dominant intermetallic phase. In addition, the substituted alloys perform clearly higher strength with comparative ductility at both as-cast and peakaged conditions and much greater aging hardening response than the referential alloy. It is obvious that the strength increments of this alloy are attributed to the changes of the eutectic intermetallic particles on grain boundaries. | Deping Zhang Qiang Yang Dongdong Zhang Kai Guan Fanqiang Bu Hong Zhou Jian Meng | 2017 | Journal of Rare Earths2017,35,12: | 5 |

| 19 | Post-marketing safety surveillance and reevaluation of Motherwort injection:A clinical study of 10094 cases显示文摘OBJECTIVE:To investigate the safety profiles of Motherwort injection(MI).METHODS:A multi-center,prospective and drugderived hospital intensive monitoring method was conducted to assess the safety of MI in real world applications.This study was based on a very large population after the injection was approved and marketed in China.All patients using the injection in participating hospitals were monitored to determine the incidence,pattern,severity and outcome of associated adverse events.RESULTS:The post-marketing surveillance was performed in 10 094 female patients from April to December,2015.The incidence of adverse drug reactions(ADRs) was 0.79‰(8/10 094).Among the 8 patients,the reported adverse events mainly included systemic abnormalities,such as fever,chills and eyelid edema;skin and appendages disorders,such as pruritus and rash;gastrointestinal disorders,such as nausea,abdominal distension and pain;heart rate and rhythm disorders,such as palpitation and increased heart rate.All of these ADRs were mild in severity.CONCLUSION:In this study the ADRs incidence rate of MI is very low,which supports that it is generally safe for use in obstetric and gynecological diseases.However,the total number of 8 ADRs recorded over a relatively short time span seems limited,and the low number of reports could not represent an absolute guarantee of safety. | Cao Shan Zhang Wenhao Zhao Ziwei Heng Mingli Bu Huaien Wang Hongwu Liu Xinghui Wang Zhong Cai Yan Ma Yuyan Cui Shihong Deng Jihong Ding Guifeng Ding Yajuan Dong Linhong Duan Zhentao Fan Ling Fan Yang Fu Fen He Jing Ji Shuying Jin Lin Li Hong Li Hongying Liao Tao Lu Wei Luo Xiucui Lü Zhihui Ma Fengchun Ma Dafeng Shi Tianyun Sun Juying Sun Xiaotong Teng Hong Wang Jinhua Wang Ruihua Wang Ying Wang Zhengling Xi Jie Xu Minjuan Xu Zhihong Yan Qian Yang Cuirong Yang Yimei Yin Jie Yu Jinhua Yuan Wenjun Zhang Guanli Zhang Meihua Zhao Renfeng Zhong Yonghong Zhou Jian | 2018 | Journal of Traditional Chinese Medicine2018,38,4: | 4 |
| 20 | Sensitivity and vulnerability of water resources in the arid Shiyang River Basin of Northwest China显示文摘The sensitivity and vulnerability of water resources to climate change is difficult to assess. In this study, we used a conceptual hydrologic model to investigate the sensitivity of streamflow to climate change. We also proposed a framework to evaluate the vulnerability of water resources in arid regions. We applied this framework to a case study of the Shiyang River Basin in Northwest China. Results showed that the precipitation and streamflow in Shiyang River Basin exhibited no significant trends of change from 1956 to 2010. In the past five decades, however, the temperature increased significantly by 0.37°C per decade. According to the sensitivity assessment, a 10% increase in precipitation and a 1°C increase in temperature altered mean annual streamflow by averages of 14.6% and –0.5%, respectively, from 1988 to 2005. In the 2000s, the calculated vulnerability of water resources in Shiyang River Basin was more than 0.95, indicating severe vulnerability. The increase in the amount of precipitation and the implementation of water-saving measures can reduce the vulnerability of water resources in the future; if precipitation increases by 10% per decade and the use of irrigation water decreases by 15% in the 2030s, the evaluated value of water resources vulnerability will be reduced to 0.79. However, the region remains highly vulnerable. The proposed framework for vulnerability assessment can be applied to the arid regions in Northwest China, and the results of our efforts can identify adaptation strategies and improve the management of water resources in such regions. | Long WAN Jun XIA HongMei BU Si HONG JunXu CHEN LiKe NING | 2014 | Journal of Arid Land2014,6,6: | 4 |
