1Synergistic Effects of Chuanxiong-Chishao Herb-Pair on Promoting Angiogenesis at Network Pharmacological and Pharmacodynamic Levels显示文摘Objective: To investigate the synergistic effects of Chuanxiong-Chishao herb-pair(CCHP) on promoting angiogenesis in silico and in vivo. Methods: The mechanisms of action of an herb-pair, ChuanxiongChishao, were investigated using the network pharmacological and pharmacodynamic strategies involving computational drug target prediction and network analysis, and experimental validation. A set of network pharmacology methods were created to study the herbs in the context of targets and diseases networks, including prediction of target profiles and pharmacological actions of main active compounds in Chuanxiong and Chishao. Furthermore, the therapeutic effects and putative molecular mechanisms of Chuanxiong-Chishao actions were experimentally validated in a chemical-induced vascular insufficiency model of transgenic zebrafish in vivo. The m RNA expression of the predicted targets were further analyzed by real-time polymerase chain reaction(RT-PCR). Results: The computational prediction results found that the compounds in Chuanxiong have antithrombotic, antihypertensive, antiarrhythmic, and antiatherosclerotic activities, which were closely related to protecting against hypoxic-ischemic encephalopathy, ischemic stroke, myocardial infarction and heart failure. In addition, compounds in Chishao were found to participate in anti-inflammatory effect and analgesics. Particularly, estrogen receptor α(ESRα) and hypoxia-inducible factor 1-α(HIF-1α) were the most important potential protein targets in the predicted results. In vivo experimental validation showed that post-treatment of tetramethylpyrazine hydrochloride(TMP·HCl) and paeoniflorin(PF) promoted the regeneration of new blood vessels in zebrafish involving up-regulating ESRα m RNA expression. Co-treatment of TMP·HCl and PF could enhance the vessel sprouting in chemical-induced vascular insufficiency zebrafish at the optimal compatibility proportion of PF 10 μmol/L with TMP·HCl 1 μmol/L. Conclusions: The network pharmacological strategies combining drug target prediction and network analysis identified some putative targets of CCHP. Moreover, the transgenic zebrafish experiments demonstrated that the Chuanxiong-Chishao combination synergistically promoted angiogenic activity, probably involving ESRα signaling pathway.WANG Yan GUO Gang YANG Bin-rui XIN Qi-qi LIAO Qi-wen LEE Simon Ming-Yuen HU Yuan-jia CHEN Ke-ji CONG Wei-hong 2017Chinese Journal of Integrative Medicine2017,23,9:19
2Insulin resistance is associated with hepatocellular carcinoma in chronic hepatitis C infection显示文摘AIM:To elucidate the role of insulin resistance(IR) and serum adiponectin level in hepatocellular carcinoma(HCC) associated with chronic hepatitis C.METHODS:Clinical and biochemical characteristics were collected from 165 consecutive patients with newly diagnosed HCC.Homeostasis model assessment of IR(HOMA-IR) and serum adiponectin level were investigated in 188 patients with different stages of hepatitis C virus(HCV) infection.RESULTS:Among HCC patients,type 2 diabetics(DM) was more prevalent in HCV subjects(35.6%,n = 59) compared to hepatitis B virus(HBV;12.7%,n = 63) or non-HBV,non-HCV cases(7.1%,n = 28).In patients with chronic hepatitis C,HCC subjects had higher blood sugar(P < 0.001),insulin level(P = 0.003) and HOMAIR(P = 0.018) than those with chronic hepatitis and advanced fibrosis.Age,male sex and body mass index were significantly associated with serum adiponectin level,whereas HOMA-IR was not.Based on stepwise logistic regression analysis,age(OR:1.124,P < 0.001),serum insulin level(OR:1.585,P < 0.001),HOMA-IR(OR:0.495,P = 0.001),DM(OR:11.601,P = 0.002) and male sex(OR:3.877,P = 0.016) were independently associated with HCC.This result was similar even if the diabetic subjects were excluded for analysis.CONCLUSION:Insulin resistance measured by HOMAIR,regardless of the presence of diabetes,is significantly associated with HCC development in patients with chronic HCV infection.Chao-Hung Hung Jing-Houng Wang Tsung-Hui Hu Chien-Hung Chen Kuo-Chin Chang Yi-Hao Yen YuanHung Kuo Ming-Chao Tsai Chuan-Mo Lee 2010World Journal of Gastroenterology2010,16,18:18

5Ciliary parathyroid hormone signaling activates transforming growth factor-βto maintain intervertebral disc homeostasis during aging显示文摘Degenerative disc disease(DDD) is associated with intervertebral disc degeneration of spinal instability. Here, we report that the cilia of nucleus pulposus(NP) cells mediate mechanotransduction to maintain anabolic activity in the discs. We found that mechanical stress promotes transport of parathyroid hormone 1 receptor(PTH1 R) to the cilia and enhances parathyroid hormone(PTH) signaling in NP cells. PTH induces transcription of integrin α_vβ_6 to activate the transforming growth factor(TGF)-β-connective tissue growth factor(CCN2)-matrix proteins signaling cascade. Intermittent injection of PTH(iPTH) effectively attenuates disc degeneration of aged mice by direct signaling through NP cells, specifically improving intervertebral disc height and volume by increasing levels of TGF-β activity, CCN2, and aggrecan. PTH1 R is expressed in both mouse and human NP cells. Importantly,knockout PTH1 R or cilia in the NP cells results in significant disc degeneration and blunts the effect of PTH on attenuation of aged discs. Thus, mechanical stress-induced transport of PTH1 R to the cilia enhances PTH signaling, which helps maintain intervertebral disc homeostasis, particularly during aging, indicating therapeutic potential of iPTH for DDD.Liwei Zheng Yong Cao Shuangfei Ni Huabin Qi Zemin Ling Xin Xu Xuenong Zou Tianding Wu Ruoxian Deng Bo Hu Bo Gao Hao Chen Yusheng Li Jianxi Zhu Francis Tintani Shadpour Demehri Amit Jain Khaled M.Kebaish Shenghui Liao Cheryle A.Séguin Janet L.Crane Mei Wan Hongbin Lu Paul D.Sponseller Lee H.RileyIII Xuedong Zhou Jianzhong Hu Xu Cao 2018Bone Research2018,6,3:13
6Essential oil of Curcuma wenyujin induces apoptosis in human hepatoma cells显示文摘AIM: To investigate the effects of the essential oil of Curcuma wenyujin (CWO) on growth inhibition and on the induction of apoptosis in human HepG2 cancer cells. METHODS: The cytotoxic effect of drugs on HepG2 cells was measured by 3-(4,5-dimethylthiazol-2- yl)-2,5-diphenyltetra-zolium bromide (MTT) assay. DNA fragmentation was visualized by agarose gel electrophoresis. Cell cycle and mitochondrial transmembrane potential (△Ψm) were determined by flow cytometry (FCM). Cytochrome C immunostaining was evaluated by fluorescence microscopy. Caspase-3 enzymatic activity was assayed by the cleavage of Ac-DEVD-R110. Cleaved PARP and active caspase-3 protein levels were measured by FCM using BD? CBA Human Apoptosis Kit. RESULTS: Treatment with CWO inhibited the growth of HepG2 cells in a dose-dependent manner, and the IC50 of CWO was approximately 70 μg/mL. CWO was found to inhibit the growth of HepG2 cells by inducing a cell cycle arrest at S/G2. DNA fragmentation was evidentlyobserved at 70 μg/mL after 72 h of treatment. During the process, cytosolic HepG2 cytochrome C staining showed a markedly stronger green fluorescence than in control cells in a dose-dependent fashion, and CWO also caused mitochondrial transmembrane depolarization. Furthermore, the results clearly demonstrated that both, activity of caspase-3 enzyme and protein levels of cleaved PARP, significantly increased in a dose- dependent manner after treatment with CWO. CONCLUSION: CWO exhibits an antiproliferative effect in HepG2 cells by inducing apoptosis. This growth inhibition is associated with cell cycle arrest, cytochrome C translocation, caspase 3 activation, Poly- ADP-ribose polymerase (PARP) degradation, and loss of mitochondrial membrane potential. This process involves a mitochondria-caspase dependent apoptosis pathway. As apoptosis is an important anti-cancer therapeutic target, these results suggest a potential of CWO as a chemotherapeutic agent.YU Xiao Feng-Qing Yang Shao-Ping Li Guang Hu Simon Ming-Yuen Lee Yi-Tao Wang 2008World Journal of Gastroenterology2008,14,27:13
7Silicon photonic platforms for mid-infrared applications [Invited]显示文摘Silicon photonic integrated circuits for telecommunication and data centers have been well studied in the past decade, and now most related efforts have been progressing toward commercialization. Scaling up the silicon-oninsulator(SOI)-based device dimensions in order to extend the operation wavelength to the short mid-infrared(MIR) range(2–4 μm) is attracting research interest, owing to the host of potential applications in lab-on-chip sensors, free space communications, and much more. Other material systems and technology platforms, including silicon-on-silicon nitride, germanium-on-silicon, germanium-on-SOI, germanium-on-silicon nitride, sapphireon-silicon, Si Ge alloy-on-silicon, and aluminum nitride-on-insulator are explored as well in order to realize low-loss waveguide devices for different MIR wavelengths. In this paper, we will comprehensively review silicon photonics for MIR applications, with regard to the state-of-the-art achievements from various device demonstrations in different material platforms by various groups. We will then introduce in detail of our institute's research and development efforts on the MIR photonic platforms as one case study. Meanwhile, we will discuss the integration schemes along with remaining challenges in devices(e.g., light source) and integration. A few application-oriented examples will be examined to illustrate the issues needing a critical solution toward the final production path(e.g., gas sensors). Finally, we will provide our assessment of the outlook of potential futureresearch topics and engineering challenges along with opportunities.TING HU BOWEI DONG XIANSHU LUO TSUNG-YANG LIOW JUNFENG SONG CHENGKUO LEE GUO-QIANG LO 2017Photonics Research2017,5,5:13
8A novel synthesis strategy to improve cycle stability of LiNio.8Mno.1Co0.1O2 at high cut-off voltages through core-shell structuring显示文摘Nickel-rich cathode materials have attracted considerable interest because of their high specific capacities,voltage ranges,and low cost.However,serious capacity attenuation and poor rate performance limit their application.This study proposes a novel strategy to improve the cycle stability of the nickel-rich LiNi0.sCo0.1Mn0.1O2(NCM811)layer material by designing core-shell LiNio.sCoo.1 Mno.102(CS-NCM811).CS-NCM811 is designed by the characteristic reaction between dimethylglyoxime(C4H8N2O2)and nickel ion to form Ni(C4H7N2O2)2-The CS-NCM811 is characterized with high nickel content in its core and high manganese content on its surface,leading to a high capacity and excellent cycle stability.The capacity retention of CS-NCM811 was 72.8%,much higher than that of NCM811(47.1%)after 500 cycles at a rate of 5 C.Not only is this method a no vel strategy to desig n high capacity cathode materials but also provides some new in sights into the cycle stability of nickel-rich layered cathode materials.Kang Wu Qi Li Rongbin Dang Xin Deng Minmin Chen Yu Lin Lee Xiaoling Xiao Zhongbo Hu 2019Nano Research2019,12,10:12
9Recent Progress in Dual-Polarization Radar Research and Applications in China显示文摘Dual-polarization(dual-pol)radar can measure additional parameters that provide more microphysical information of precipitation systems than those provided by conventional Doppler radar.The dual-pol parameters have been successfully utilized to investigate precipitation microphysics and improve radar quantitative precipitation estimation(QPE).The recent progress in dual-pol radar research and applications in China is summarized in four aspects.Firstly,the characteristics of several representative dual-pol radars are reviewed.Various approaches have been developed for radar data quality control,including calibration,attenuation correction,calculation of specific differential phase shift,and identification and removal of non-meteorological echoes.Using dual-pol radar measurements,the microphysical characteristics derived from raindrop size distribution retrieval,hydrometeor classification,and QPE is better understood in China.The limited number of studies in China that have sought to use dual-pol radar data to validate the microphysical parameterization and initialization of numerical models and assimilate dual-pol data into numerical models are summarized.The challenges of applying dual-pol data in numerical models and emerging technologies that may make significant impacts on the field of radar meteorology are discussed.Kun ZHAO Hao HUANG Mingjun WANG Wen-Chau LEE Gang CHEN Long WEN Jing WEN Guifu ZHANG Ming XUE Zhengwei YANG Liping LIU Chong WU Zhiqun HU Sheng CHEN 2019Advances in Atmospheric Sciences2019,36,9:12
10Adjuvant heparanase inhibitor PI-88 therapy for hepatocellular carcinoma recurrence显示文摘AIM: To demonstrate that administering heparanase inhibitor PI-88 at 160 mg/d is safe and promising in reducing hepatocellular carcinoma(HCC) recurrence for up to 3 year following curative resection. METHODS: A total of 143 patients(83.1% of the 172 participants in the phase Ⅱ study) participated in the follow-up study. Of these patients, 50 had received no treatment, 48 had received 160 mg/d PI-88, and 45 had received 250 mg/d PI-88 during the phase Ⅱ trial. Safety parameters and the following efficacy endpoints were investigated:(1) time to recurrence;(2) diseasefree survival; and(3) overall survival. RESULTS: PI-88 at 160 mg/d delayed the onset and frequency of HCC recurrence, and provided a clinically significant survival advantage for up to 3 years after treatment compared with those of the control group:(1) the recurrence-free rate increased from 50% to 63%, and(2) time to recurrence at the 36 th percentile was postponed by 78%. The efficacy of administering PI-88 at 250 mg/d was confounded by a high dropout rate(11 out of 54 patients). Additionally, subgroup analyses of patients with(1) multiple tumors or a single tumor ≥ 2 cm; and(2) hepatitis B or C revealed that administering PI-88 at 160 mg/d conferred the most significant survival advantage(56.8% improvement in disease-free survival, P = 0.045) for patients with both risk factors for recurrence. CONCLUSION: Administering PI-88 at 160 mg/d is a safe and well-tolerated dosage that may confer significant clinical benefits for patients with HCC.Chun-Jen Liu Juliana Chang Po-Huang Lee Deng-Yn Lin Cheng-Chung Wu Long-Bin Jeng Yih-Jyh Lin King-Tong Mok Wei-Chen Lee Hong-Zen Yeh Ming-Chih Ho Sheng-Shun Yang Mei-Due Yang Ming-Chin Yu Rey-Heng Hu Cheng-Yuan Peng Kuan-Lang Lai Stanley Shi-Chung Chang Pei-Jer Chen 2014World Journal of Gastroenterology2014,20,32:11

12HNF-4α determines hepatic differentiation of human mesenchymal stem cells from bone marrow显示文摘AIM: To investigate the differentiation status and key factors to facilitate hepatic differentiation of human bone-marrow-derived mesenchymal stem cells (MSCs). METHODS: Human MSCs derived from bone marrow were induced into hepatocyte-like cells following a previously published protocol. The differentiation status of the hepatocyte-like cells was compared with various human hepatoma cell lines. Overexpression of hepatocyte nuclear factor (HNF)-4α was mediated by adenovirus infection of these hepatocyte-like cells. The expression of interesting genes was then examined by either re-verse transcription-polymerase chain reaction (RT-PCR) or real-time RT-PCR methods. RESULTS: Our results demonstrated that the differentiation status of hepatocyte-like cells induced from human MSCs was relatively similar to poorly differentiated human hepatoma cell lines. Interestingly, the HNF-4 isoform in induced MSCs and poorly differentiated human hepatoma cell lines was identified as HNF4γ instead of HNF-4α. Overexpression of HNF-4α in induced MSCs significantly enhanced the expression level of hepatic-specific genes, liver-enriched transcription factors, and cytochrome P450 (P450) genes. CONCLUSION: Overexpression of HNF-4α improves the hepatic differentiation of human MSCs from bone marrow and is a simple way of providing better cell sources for clinical applications.Mong-Liang Chen Kuan-Der Lee Huei-Chun Huang Yue-Lin Tsai Yi-Chieh Wu Tzer-Min Kuo Cheng-Po Hu Chungming Chang 2010World Journal of Gastroenterology2010,16,40:9
13SARS-CoV-2 infects human neural progenitor cells and brain organoids显示文摘Dear Editor,Coronavirus disease 2019(COVID-19)caused by the novel severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)1 has resulted in over 13 million confirmed cases and more than 580,045 deaths across 218 countries and geographical regions as of July 16,2020.This novel coronavirus primarily causes respiratory illness with clinical manifestations largely resembling those of SARS.However,neurological symptoms including headache,anosmia,ageusia,confusion,seizure,and encephalopathy have also been frequently reported in COVID-19 patients.Bao-Zhong Zhang Hin Chu Shuo Han Huiping Shuai Jian Deng Ye-fan Hu Hua-rui Gong Andrew Chak-Yiu Lee Zijiao Zou Thomas Yau Wutian Wu Ivan Fan-Ngai Hung Jasper Fuk-Woo Chan Kwok-Yung Yuen Jian-Dong Huang 2020Cell Research2020,30,10:8
14Prophylactic liver transplantation for high-risk recurrent hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC) is the second most common cause of cancer-related death in the world. Radical treatment of HCC in early stages results in a long disease-free period and improved overall survival. The choice of optimal management strategy for HCC mainly depends on the severity of the underlying liver disease. For patients with decompensated liver cirrhosis and HCC within Milan criteria(MC), liver transplant(LT) is the choice of treatment. However, for patients with good residual liver reserve and HCC within MC, selection of other curative treatments such as liver resection(LR) or radiofrequency ablation may be a reasonable alternative. For patients without cirrhosis, LR can result in an overall survival similar to that provided by LT. Therefore, it is an accepted alternative to LT especially in areas with organ shortage. However, the cumulative 5-year recurrence rate of HCC post LR might be as high as 70%. For initial transplant-eligible(within MC) patients with recurrent HCC post LR, salvage liver transplant(SLT) was first proposed in 2000. However, most patients with recurrent HCC considered for SLT are untransplantable cases due to HCC recurrence beyond MC or comorbidity. Thus, the strategy of opting for SLT results in the loss of the opportunity of LT for these patients. Some authors proposed the concept of 'de principe liver transplant'(i.e., prophylactic LT before HCC recurrence) to prevent losing the chance of LT for these potential candidates. Factors associated with the failure of SLT will be dissected and discussed in three parts: Patient, tumor, and underlying liver disease. Regarding patient-related factors, the rate of transplantability depends on patient compliance. Patients without regular follow-up tend to develop HCC recurrence beyond MC at the time of tumor detection. Advancing age is another factor related to severe comorbidities when LT is considered for HCC recurrence, and these elderly candidates become ineligible as time goes by. Regarding tumor-related factors, histopathological features of the resected specimen are used mostly for determining the prognosis of early HCC recurrences. Suchprognostic factors include the presence of microvascular invasion, poor tumor differentiation, the presence of microsatellites, the presence of multiple tumors, and the presence of the gene-expressing signature associated with aggressive HCC. These prognostic factors might be used as a selection tool for SLT or prophylactic LT, while remaining mindful of the fact that most of them are also prognostic factors for post-transplant HCC recurrence. Regarding underlying liver disease-related factors, progression of chronic viral hepatitis and high viral load may contribute to the development of late(de novo) HCC recurrence as a consequence of sustained inflammatory reaction. However, correlation between the severity of liver fibrosis and tumor recurrence is still controversial. Some prognostic scoring systems that integrate these three factors have been proposed to predict recurrence patterns after LR for HCC. Theoretically, after excluding patients with high risk of post-transplant HCC recurrence, either by observation of a cancer-free period or by measurement of biological factors(such as alpha fetoprotein), prophylactic LT following curative resection of HCC could be considered for selected patients with high risk of recurrence to provide longer survival.Po-Chih Yang Cheng-Maw Ho Rey-Heng Hu Ming-Chih Ho Yao-Ming Wu Po-Huang Lee 2016World Journal of Hepatology2016,8,31:6
15Wolf phase tomography(WPT) of transparent structures using partially coherent illumination显示文摘In 1969,Emil Wolf proposed diffraction tomography using coherent holographic imaging to extract 3D information from transparent,inhomogeneous objects.In the same era,the Wolf equations were first used to describe the propagation correlations associated with partially coherent fields.Combining these two concepts,we present Wolf phase tomography(WPT),which is a method for performing diffraction tomography using partially coherent fields.WPT reconstruction works directly in the space-time domain,without the need for Fourier transformation,and decouples the refractive index(RI)distribution from the thickness of the sample.We demonstrate the WPT principle using the data acquired by a quantitative-phase-imaging method that upgrades an existing phase-contrast microscope by introducing controlled phase shifts between the incident and scattered fields.The illumination field in WPT is partially spatially coherent(emerging from a ring-shaped pupil function)and of low temporal coherence(white light),and as such,it is well suited for the Wolf equations.From three intensity measurements corresponding to different phase-contrast frames,the 3D RI distribution is obtained immediately by computing the Laplacian and second time derivative of the measured complex correlation function.We validate WPT with measurements of standard samples(microbeads),spermatozoa,and live neural cultures.The high throughput and simplicity of this method enables the study of 3D,dynamic events in living cells across the entire multiwell plate,with an RI sensitivity on the order of 10^(−5).Xi Chen Mikhail E.Kandel Chenfei Hu Young Jae Lee Gabriel Popescu 2020Light(Science & Applications)2020,9,1:6
16Serum hepatitis B surface antigen levels predict treatment response to nucleos(t)ide analogues显示文摘Quantification of hepatitis B surface antigen(HBsAg)has been suggested to be helpful in the management of chronic hepatitis B(CHB)patients.Nucleos(t)ide analogs(NAs)are the therapy of choice for CHB and are used in the majority of CHB patients.NAs are able to induce hepatitis B virus(HBV)viral suppression,normalization of alanine aminotransferase(ALT)levels,and improvement in liver histology.Automated quantitative assays for serum HBsAg have recently become available,facilitating standardized quantification of serum HBsAg.This has led to increased interest in the clinical application of quantitative serum HBsAg for predicting therapeutic response to NAs.Recent studies have shown that a decline in serum HBsAg levels in patients receiving peginterferon may signal successful induction of immune control over HBV,and can therefore be used to predict therapeutic response.NA treatment typically induces a less rapid decline in HBsAg than interferon treatment;it has been estimated that full HBsAg clearance can require decades of NA treatment.However,a rapid HBsAg decline during NA therapy may identify patients who will show clearance of HBsAg.Currently,there is no consensus on the clinical utility of serum HBsAg monitoring for evaluating patient responses to NA therapy.This review focuses on recent findings regarding the potential application of HBsAg quantification in the management of CHB patients receiving NA therapy.Chien-Hung Chen Yi-Chun Chiu Sheng-Nan Lu Chuan-Mo Lee Jing-Houng Wang Tsung-Hui Hu Chao-Hung Hung 2014World Journal of Gastroenterology2014,20,24:6

19An herbal formula,CGX,exerts hepatotherapeutic effects on dimethylnitrosamine-induced chronic liver injury model in rats显示文摘AIM: To evaluate the therapeutic effect of Chunggan extract (CGX), a modified traditional Chinese hepatotherapeutic herbal, on the dimethylnitrosamine (DMN)-induced chronic liver injury model in rats. METHODS: Liver injuries were induced in Wistar rats by injection of DMN (ip, 10 mg/mL per kg) for 3 consecutive days per week for 4 wk. The rats were administered with CGX (po, 100 or 200 mg/kg per day) or distilled water as a control daily for 4 wk starting from the 15th d of the DMN treatment. Biochemical parameters (serum albumin, bilirubin, ALP, AST and ALT), lipid peroxides, hydroxyproline, as well as histological changes in liver tissues were analyzed. In addition, gene expression of TNF-α, TGF-b, TIMP-1, TIMP-2, PDGF-b, and MMP-2, all of which are known to be associated with liver fibrosis, were analyzed using real-time PCR. RESULTS: CGX administration restored the spleen weight to normal after having been increased by DMN treatment. Biochemical analysis of the serum demonstrated that CGX significantly decreased the serum level of ALP (P < 0.05), ALT (P < 0.01), and AST (P < 0.01) that had been elevated by DMN treatment. CGX administration moderately lowered lipid peroxide production and markedly lowered hydroxyproline generation caused by DMN treatment in accordance with histopathological examination. DMN treatment induced a highly up-regulated expression of TNF-α, TGF-b, TIMP-1, TIMP-2, PDGF-b, and MMP-2. Of these, the gene expression encoding PDGF-b and MMP-2 was still further enhanced 2 wk after secession of the 4-wk DMN treatment, and was remarkably ameliorated by CGX administration. CONCLUSION: CGX exhibits hepatotherapeutic proper- ties against chronic hepatocellular destruction and consequential liver fibrosis.Jang-Woo Shin Jin-Young Son Se-Mi Oh Seung-Hyun Han Jing-Hua Wang Jung-Hyo Cho Chong-Kwan Cho Hwa-Seung Yoo Yeon-Weol Lee Myong-Min Lee Xiao Ping Hu Chang-Gue Son 2006World Journal of Gastroenterology2006,12,38:5
20Risk factor for ischemic-type biliary lesion after ABO-incompatible living donor liver transplantation显示文摘AIM: To evaluate the risk factors for ischemic-type biliary lesion(ITBL) after ABO-incompatible(ABO-I) adult living donor liver transplantation(ALDLT).METHODS: Among 141 ALDLTs performed in our hospital between 2008 and 2014, 27(19%) were ABO-I ALDLT and 114 were ABO-identical/compatible ALDLT. In this study, we extensively analyzed the clinico-pathological data of the 27 ABO-I recipients to determine the risk factors for ITBL after ABO-I ALDLT. All ABO-I ALDLT recipients underwent an identical B-cell depletion protocol with preoperative rituximab, plasma exchange(PE), and operative splenectomy. The median follow-up period after transplantation was 26 mo. The clinical outcomes of the 27 ABO-I ALDLT recipients were compared with those of 114 ABO-identical/compatible ALDLT recipients.RESULTS: ITBL occurred in four recipients(14.8%) between 45 and 112 d after ABO-I ALDLT. The overall survival rates were not different between ABO-I ALDLT and ABO-identical/compatible ALDLT(P = 0.303). Among the ABO-I ALDLT recipients, there was no difference between patients with ITBL and those without ITBL in terms of B-cell and T-cell count, serum isoagglutinin titers, number of PEs, operative time and transfusion, use of graft infusion therapy, or number of remnant B-cell follicles and plasma cells in the spleen. However, the perioperative NK cell counts in the blood of patients with ITBL were significantly higher than those in the patients without ITBL(P < 0.05). Preoperative NK cell count > 150/μL and postoperative NK cell count > 120/μL were associated with greater relative risks(RR) for development of ITBL(RR = 20 and 14.3, respectively, P < 0.05). CONCLUSION: High NK cell counts in a transplant recipient's blood are associated with ITBL after ABO-I ALDLT. Further research is needed to elucidate the molecular mechanism of NK cell involvement in the development of ITBL.Jun Bae Bang Bong-Wan Kim Young Bae Kim Hee-Jung Wang Hyun Yeong Lee Joohyun Sim Taegyu Kim Kyeong Lok Lee Xu-Guang Hu Wei Mao 2016World Journal of Gastroenterology2016,22,30:5
