| 1 | A new prognostic histopathologic classification of nasopharyngeal carcinoma显示文摘Background:The current World Health Organization(WHO) classification of nasopharyngeal carcinoma(NPC) con?veys little prognostic information.This study aimed to propose an NPC histopathologic classification that can poten?tially be used to predict prognosis and treatment response.Methods:We initially developed a histopathologic classification based on the morphologic traits and cell differentia?tion of tumors of 2716 NPC patients who were identified at Sun Yat?sen University Cancer Center(SYSUCC)(training cohort).Then,the proposed classification was applied to 1702 patients(retrospective validation cohort) from hospitals outside SYSUCC and 1613 patients(prospective validation cohort) from SYSUCC.The efficacy of radiochemotherapy and radiotherapy modalities was compared between the proposed subtypes.We used Cox proportional hazards models to estimate hazard ratios(HRs) with 95% confidence intervals(CI) for overall survival(OS).Results:The 5?year OS rates for all NPC patients who were diagnosed with epithelial carcinoma(EC;3708 patients),mixed sarcomatoid?epithelial carcinoma(MSEC;1247 patients),sarcomatoid carcinoma(SC;823 patients),and squamous cell carcinoma(SCC;253 patients) were 79.4%,70.5%,59.6%,and 42.6%,respectively(P < 0.001).In mul?tivariate models,patients with MSEC had a shorter OS than patients with EC(HR = 1.44,95% CI = 1.27–1.62),SC(HR = 2.00,95% CI = 1.76–2.28),or SCC(HR = 4.23,95% CI = 3.34–5.38).Radiochemotherapy significantly improved survival compared with radiotherapy alone for patients with EC(HR 49–0.75),and possibly for those with SCC(HR = 0.67,95% CI = 0.56–0.80),MSEC(HR = 0.58,95% CI = 0..74–1.28).= 0.63;95% CI = 0.40–0.98),but not for patients with SC(HR = 0.97,95% CI = 0Conclusions:The proposed classification offers more information for the prediction of NPC prognosis compared with the WHO classification and might be a valuable tool to guide treatment decisions for subtypes that are associ?ated with a poor prognosis. | Hai-Yun Wang Yih-Leong Chang Ka-Fai To Jacqueline S.G.Hwang Hai-Qiang Mai Yan-Fen Feng Ellen T.Chang Chen-Ping Wang Michael Koon Ming Kam Shie-Lee Cheah Ming Lee Li Gao Hui-Zhong Zhang Jie-Hua He Hao Jiang Pei-Qing Ma Xiao-Dong Zhu Liang Zeng Chun-Yan Chen Gang Chen Ma-Yan Huang Sha Fu Qiong Shao An-Jia Han Hai-Gang Li Chun-Kui Shao Pei-Yu Huang Chao-Nan Qian Tai-Xiang Lu Jin-Tian Li Weimin Ye Ingemar Ernberg Ho Keung Ng Joseph T.S.Wee Yi-Xin Zeng Hans-Olov Adami Anthony T.C.Chan Jian-Yong Shao | 2016 | Chinese Journal of Cancer2016，35，6： | 10 |
| 2 | Clinical significance of hepatic derangement in severe acute respiratory syndrome显示文摘AIM: Elevation of alanine aminotransferase (ALT) level is commonly seen among patients suffering from severe acute respiratory syndrome (SARS). We report the progression and clinical significance of liver derangement in a large cohort of SARS patient.METHODS: Serial assay of serum ALT was followed in patients who fulfilled the WHO criteria of SARS. Those with elevated ALT were compared with those with normal liver functions for clinical outcome. Serology for hepatitis B virus (HBV) infection was checked. Adverse outcomes were defined as oxygen desaturation, need of intensive care unit (ICU) and mechanical ventilation and death.RESULTS: Two hundred and ninety-four patients were included in this study. Seventy (24%) patients had elevated serum ALT on admission and 204 (69%) patients had elevated ALT during the subsequent course of illness. Using peak ALT >5×ULN as a cut-off and after adjusting for potential confounding factors, the odds ratio of peak ALT>5x ULN for oxygen desaturation was 3.24 (95%CI 1.23-8.59, P = 0.018), ICU care was 3.70 (95% CI 1.38-9.89, P = 0.009), mechanical ventilation was 6.64 (95%CI 2.22-19.81, P = 0.001) and death was 7.34(95%CI 2.28-24.89, P = 0.001). Ninety-three percent of the survived patients had ALT levels normalized or were on the improving trend during follow-up. Chronic hepatitis B was not associated with worse clinical outcomes.CONCLUSION: Reactive hepatitis is a common complication of SARS-coronavirus infection. Those patients with severe hepatitis had worse clinical outcome. | Henry Lik-Yuen Chan Ambrose Chi-Pong Kwan Ka-Fai To Sik-To Lai Paul Kay-Sheung Chan Wai-Keung Leung Nelson Lee Alan Wu Joseph Jao-Yiu Sung | 2005 | World Journal of Gastroenterology2005，11，14： | 4 |

| 4 | Aberrant cholesterol metabolic signaling impairs antitumor immunosurveillance through natural killer T cell dysfunction in obese liver显示文摘Obesity is a major risk factor for cancers including hepatocellular carcinoma(HCC)that develops from a background of non-alcoholic fatty liver disease(NAFLD).Hypercholesterolemia is a common comorbidity of obesity.Although cholesterol biosynthesis mainly occurs in the liver,its role in HCC development of obese people remains obscure.Using high-fat high-carbohydrate diet-associated orthotopic and spontaneous NAFLD-HCC mouse models,we found that hepatic cholesterol accumulation in obesity selectively suppressed natural killer T(NKT)cell-mediated antitumor immunosurveillance.Transcriptome analysis of human liver revealed aberrant cholesterol metabolism and NKT cell dysfunction in NAFLD patients.Notably,cholesterol-lowering rosuvastatin restored NKT expansion and cytotoxicity to prevent obesogenic diet-promoted HCC development.Moreover,suppression of hepatic cholesterol biosynthesis by a mammalian target of rapamycin(mTOR)inhibitor vistusertib preceded tumor regression,which was abolished by NKT inactivation but not CD8^(+)T cell depletion.Mechanistically,sterol regulatory element-binding protein 2(SREBP2)-driven excessive cholesterol production from hepatocytes induced lipid peroxide accumulation and deficient cytotoxicity in NKT cells,which were supported by findings in people with obesity,NAFLD and NAFLD-HCC.This study highlights mTORC1/SREBP2/cholesterol-mediated NKT dysfunction in the tumor-promoting NAFLD liver microenvironment,providing intervention strategies that invigorating NKT cells to control HCC in the obesity epidemic. | Wenshu Tang Jingying Zhou Weiqin Yang Yu Feng Haoran Wu Myth T.S.Mok Lingyun Zhang Zhixian Liang Xiaoyu Liu Zhewen Xiong Xuezhen Zeng Jing Wang Jiahuan Lu Jingqing Li Hanyong Sun Xiaoyu Tian Philip Chun Yeung Yong Hou Heung Man Lee Candice C.H.Lam Howard H.W.Leung Anthony W.H.Chan Ka Fai To John Wong Paul B.S.Lai Kelvin K.C.Ng Simon K.H.Wong Vincent W.S.Wong Alice P.S.Kong Joseph J.Y.Sung Alfred S.L.Cheng | 2022 | Cellular & Molecular Immunology2022，19，7： | 3 |
| 5 | Mesoplasticity Approach to Studies of the Cutting Mechanism in Ultra-precision Machining显示文摘There have been various theoretical attempts by researchers worldwide to link up different scales of plasticity studies from the nano-, micro- and macro-scale of observation, based on molecular dynamics, crystal plasticity and continuum mechanics. Very few attempts, however, have been reported in ultra-precision machining studies. A mesoplasticity approach advocated by Lee and Yang is adopted by the authors and is successfully applied to studies of the micro-cutting mechanisms in ultra-precision machining. Traditionally, the shear angle in metal cutting, as well as the cutting force variation, can only be determined from cutting tests. In the pioneering work of the authors, the use of mesoplasticity theory enables prediction of the fluctuation of the shear angle and micro-cutting force, shear band formation, chip morphology in diamond turning and size effect in nano-indentation. These findings are verified by experiments. The mesoplasticity formulation opens up a new direction of studies to enable how the plastic behaviour of materials and their constitutive representations in deformation processing, such as machining can be predicted, assessed and deduced from the basic properties of the materials measurable at the microscale. | LEE WB Rongbin WANG Hao TO Suet CHEUNG Chi Fai CHAN Chang Yuen | 2014 | Chinese Journal of Mechanical Engineering2014，27，2： | 2 |
