1Topical application of glycyrrhizin preparation ameliorates experimentally induced colitis in rats显示文摘AIM:To examine the efficacy of glycyrrhizin preparation(GL-p) in the treatment of a rat model of ulcerative colitis(UC).METHODS:Experimental colitis was induced by oral administration of dextran sodium sulfate.Rats with colitis were intrarectally administered GL-p or saline.The extent of colitis was evaluated based on body weight gain,colon wet weight,and macroscopic damage score.The expression levels of pro-inflammatory cytokines and chemokines in the inflamed mucosa were measured by cytokine antibody array analysis.The effect of GL-p on myeloperoxidase(MPO) activity in the inflamed mucosa and purified enzyme was assayed.RESULTS:GL-p treatment significantly ameliorated the extent of colitis compared to sham treatment with saline.Cytokine antibody array analysis showed that GL-p treatment significantly decreased the expression levels of pro-inflammatory cytokines and chemokines,including interleukin(IL)-1β,IL-6,tumor necrosis factor-α,cytokine-induced neutrophil chemoattractant-2,and monocyte chemoattractant protein-1 in the inflamed mucosa.Furthermore,GL-p inhibited the oxidative activity of mucosal and purified MPO.CONCLUSION:GL-p enema has a therapeutic effect on experimental colitis in rats and may be useful in the treatment of UC.Tomohiro Kudo Shinichi Okamura Yajing Zhang Takashige Masuo Masatomo Mori 2011World Journal of Gastroenterology2011,17,17:23
2Analysis of ABC (D) stratification for screening patients with gastric cancer显示文摘AIM:To evaluate the value of ABC(D) stratification [combination of serum pepsinogen and Helicobacter pylori(H.pylori) antibody]of patients with gastric cancer.METHODS:Ninety-five consecutive patients with gastric cancer were enrolled into the study.The serum pepsinogenⅠ(PGⅠ) /pepsinogenⅡ(PGⅡ) and H.pylori antibody levels were measured.Patients were classified into five groups of ABC(D) stratification according to their serological status.Endoscopic findings of atrophic gastritis and histological differentiation were also analyzed in relation to the ABC(D) stratification.RESULTS:The mean patient age was(67.9±8.9) years.Three patients(3.2%) were classified into group A,7 patients(7.4%) into group A',27 patients(28.4%) into group B,54 patients(56.8%) into group C,and 4patients(4.2%) into group D,respectively.There were only three cases in group A when the patients taking acid proton pump inhibitors and those who had undergone eradication therapy for H.pylori(group A') were excluded.These three cases had mucosal atrophy in the grey zone according to the diagnostic manual of ABC(D) stratification.Histologically,the mean age of the patients with well differentiated adenocarcinoma was significantly higher than that of the patients with poorly differentiated adenocarcinoma(P<0.05) .There were no differences in the pattern of atrophy in the endoscopies between the well differentiated and poorly differentiated groups.CONCLUSION:ABC(D) stratification is a good method for screening patients with gastric cancers.Endoscopy is needed for grey zone cases to check the extent of mucosal atrophy.Tomohiro Kudo Satoru Kakizaki Naondo Sohara Yasuhiro Onozato Shinichi Okamura Yoshikatsu Inui Masatomo Mori 2011World Journal of Gastroenterology2011,17,43:17
3Autoimmune thrombocytopenia in response to splenectomy in cirrhotic patients with accompanying hepatitis C显示文摘瞄准:估计自体免疫的血小板减少的贡献到丙肝病毒相关的肝肝硬化(类型 C 肝硬化) ,我们在联系血小板的免疫球蛋白 G (PAIgG ) 层次和血小板数字之上评估了脾切除术的影响。方法:PAIgG 乳头 ers 和有免疫力的标记与一口未经触动的怒气与一口未经触动的怒气,提交到脾切除术的 17 个类型 C 肝脏硬化症的病人,和 21 non-C 肝硬化在 24 个类型 C 肝脏硬化症的病人被决定。结果:血小板减少(PLT < 15 x 10 (4 )/microL ) 在类型 C,肝硬化与一口未经触动的怒气在所有病人被诊断,提交到脾切除术的 8 个病人,并且在有未经触动的怒气的 19 non-C 肝硬化。在超过 25.0 ng/10 (7 ) 的 PAIgG 的提高的乳头 ers 房间除了一个 splenectomized 病人在所有肝脏硬化症的病人被检测。PAIgG 乳头 ers (ng/10 (7 ) 房间) 与 splenectomized 病人(125.6+/-87.8 ) 或 non-C 肝硬化(152.4+/-127.4 ) 相比在有一口未经触动的怒气(247.9+/-197.0 ) 的类型 C 肝硬化是显著地更高的。PAIgG 乳头 ers 否定地与一口未经触动的怒气在类型 C 肝脏硬化症的病人与血小板计数被相关。与有一口未经触动的怒气的类型 C 肝硬化比较, splenectomized 病人有减少的 CD4/CD8 比率和浆液 neopterin 层次。怒气索引(cm2 ) 否定地在 non-C 肝硬化,然而并非在类型 C 肝硬化与血小板计数被相关。结论:我们的数据显示自体免疫的机制在由 HCV 积极的肝硬化复杂的血小板增多起一个重要作用。另外,脾切除术可以损害 T 房间功能通过,至少部分地, CD4/CD8 比率的减小,因而压制 PAIgG 生产。Tetsuro Sekiguchi Takeaki Nagamine Hitoshi Takagi Masatomo Mori 2006World Journal of Gastroenterology2006,12,8:16

5Comparison of endoscopic stenting for malignant biliary obstruction: A single-center study显示文摘AIM: To evaluate the efficacy and safety of single-step endoscopic placement of self-expandable metallic stents(SEMS) for treatment of obstructive jaundice.METHODS: A retrospective study was performed among 90 patients who underwent transpapillary biliary metallic stent placement for malignant biliary obstruction(MBO) between April 2005 and October 2012. The diagnosis of primary disease and MBO was based on abdominal ultrasound, computed tomography, magnetic resonance imaging, endoscopic ultrasound, endoscopic retrograde cholangiopancreatography with brush cytology, biopsy, and/or a combination of these modalities. The type of SEMS(covered or non-covered, 8 mm or 10 mm in diameter) was determined by the endoscopist. Ninety patients were divided into two groups: group 1(49 patients) who underwent a singlestep SEMS placement and group 2(41 patients) who underwent a two-step SEMS placement. The technical success rate, complication rate, stent patency, and patient survival rate were compared between the groups. In addition, to identify the clinical prognostic factors associated with patient survival, the following variables were evaluated in Cox-regression analysis: gender, age, etiology of MBO(pancreatic cancer or nonpancreatic cancer), clinical stage(Ⅳb; with distant metastases or Ⅳa >; without distant metastases), chemotherapy(with or without), patency of the stent, and the use of single-step or two-step SEMS. RESULTS: Immediate technical success was achieved in 93.9%(46/49) in group 1 and in 95.1%(39/41) in group 2, with no significant difference(P = 1.0). Similarly, there was no difference in the complication rates between the groups(group 1, 4.1% and group 2, 4.9%; P = 0.62). Stent failure was observed in 10 cases in group 1(20.4%) and in 16 cases in group 2(39.0%). The patency of stent and patient survival revealed no difference between the two groups with Kaplan-Meier analysis, with a mean patency of 111 ± 17 d in group 1 and 137 ± 19 d in group 2(P = 0.91), and a mean survival of 178 ± 35 d in group 1 and 222 ± 23 d in group 2(P = 0.57). On the contrary, the number of days of hospitalization associated with first-time SEMS placement in group 1 was shorter when compared with that number in group 2(28 vs 39 d; P < 0.05). Multivariate analysis revealed that a clinical stage of Ⅳa >(P = 0.0055), chemotherapy(P = 0.0048), and no patency of the stent(P = 0.011) were independent prognostic factors associated with patient survival.CONCLUSION: Our results showed that single-step endoscopic metal stent placement was safe and effective for treating obstructive jaundice secondary to various inoperable malignancies.Ryuichi Yamamoto Masatomo Takahashi Yasuyo Osafune Katsuya Chinen Shingo Kato Sumiko Nagoshi Koji Yakabi 2015World Journal of Gastrointestinal Endoscopy2015,7,9:12

7Hepatocellular carcinoma in extremely elderly patients:An analysis of clinical characteristics,prognosis and patient survival显示文摘瞄准:80 年或更多与肝细胞癌(HCC ) 识别病人的临床、预示的特征。方法:有 HCC 的 1310 个病人的一个总数在这研究被包括。80 年或更多的 91 个病人在 HCC 的诊断的时候被定义为极其老的组。> 或 = 的 234 个病人 50 年但是不到 60 年被认为是非老的组。结果:两性比率(到女性的男性) 比在非老的组在极其老的组(0.90:1 ) 是显著地更低的(3.9:1, P < 0.001 ) 。为 HBsAg 的积极的率在极其老的组和为显然在极其老的组增加的 HBsAg 和 HCVAb 否定的病人的比例是显著地更低的(P < 0.001 ) 。在下列参数没有有效差量:肿瘤,分级的孩子呸,肿瘤阶段,门静脉血栓形成或腹水的存在,和为 HCVAb 的积极的率的直径和数字。极其老的病人经常没收到外科疗法(P < 0.001 ) 并且他们是更可能的收到保守疗法(P < 0.01 ) 。基于与在二个组之间的全面病人比较的 Kaplan-Meier 方法在幸存曲线没有有效差量。然而,幸存曲线在有阶段 I/II 的极其老的病人是显著地更坏的,上演 I/II,孩子呸分级与非老的组比较的肝硬化。死亡的原因没在病人之中不同,并且大多数盒子甚至在极其老的病人死于肝相关的疾病。结论:在有好肝功能和好表演地位的病人,为 HCC 的好攻击的治疗可能改进幸存率,甚至在极其老的病人。Gengo Tsukioka Satoru Kakizaki Naondo Sohara Ken Sato Hitoshi Takagi Hirotaka Arai Takehiko Abe Mitsuo Toyoda Kenji Katakai Akira Kojima Yuichi Yamazaki Toshiyuki Otsuka Yutaka Matsuzaki Fujio Makita Daisuke Kanda Katsuhiko Horiuchi Tetsuya Hamada Mieko Kaneko Hideyuki Suzuki Masatomo Mori 2006World Journal of Gastroenterology2006,12,1:7
8Analysis of colonoscopic perforations at a local clinic and a tertiary hospital显示文摘AIM:To define the clinical characteristics,and to assess the management of colonoscopic complications at a local clinic.METHODS:A retrospective review of the medical records was performed for the patients with iatrogenic colon perforations after endoscopy at a local clinic between April 2006 and December 2010.Data obtained from a tertiary hospital in the same region were also analyzed.The underlying conditions,clinical presentations,perforation locations,treatment types(operative or conservative) and outcome data for patients at the local clinic and the tertiary hospital were compared.RESULTS:A total of 10 826 colonoscopies,and 2625 therapeutic procedures were performed at a local clinic and 32 148 colonoscopies,and 7787 therapeutic procedures were performed at the tertiary hospital.The clinic had no perforations during diagnostic colonoscopy and 8(0.3%) perforations were determined to be related to therapeutic procedures.The perforation rates in each therapeutic procedure were 0.06%(1/1609) in polypectomy,0.2%(2/885) in endoscopic mucosal resection(EMR),and 3.8%(5/131) in endoscopic submucosal dissection(ESD).Perforation rates for ESD were significantly higher than those for polypectomy or EMR(P < 0.01).All of these patients were treated conservatively.On the other hand,three(0.01%) perforation cases were observed among the 24 361 diagnostic procedures performed,and these cases were treated with surgery in a tertiary hospital.Six perforations occurred with therapeutic endoscopy(perforation rate,0.08%;1 per 1298 procedures).Perforation rates for specific procedure types were 0.02%(1 per 5500) for polypectomy,0.17%(1 per 561) for EMR,2.3%(1 per 43) for ESD in the tertiary hospital.There were no differences in the perforation rates for each therapeutic procedure between the clinic and the tertiary hospital.The incidence of iatrogenic perforation requiring surgical treatment was quite low in both the clinic and the tertiary hospital.No procedure-related mortalities occurred.Performing closure with endoscopic clipping reduced the C-reactive protein(CRP) titers.The mean maximum CRP titer was 2.9 ± 1.6 mg/dL with clipping and 9.7 ± 6.2 mg/dL without clipping,respectively(P < 0.05).An operation is indicated in the presence of a large perforation,and in the setting of generalized peritonitis or ongoing sepsis.Although we did not experience such case in the clinic,patients with large perforations should be immediately transferred to a tertiary hospital.Good relationships between local clinics and nearby tertiary hospitals should therefore be maintained.CONCLUSION:It was therefore found to be possible to perform endoscopic treatment at a local clinic when sufficient back up was available at a nearby tertiary hospital.Toshihiko Sagawa Satoru Kakizaki Haruhisa Iizuka Yasuhiro Onozato Naondo Sohara Shinichi Okamura Masatomo Mori 2012World Journal of Gastroenterology2012,18,35:5
9Helicobacter heilmannii sensu stricto-related gastric ulcers:A case report显示文摘A spiral bacterium(SH9),morphologically different from Helicobacter pylori(H.pylori),was found in a 62-yearold woman’s gastric mucosa.Gastroscopic examination revealed multiple gastric ulcers near the pyloric ring;mapping gastric biopsy showed mild mononuclear infiltration with large lymphoid follicles in the antrum,without corpus atrophy.Urea breath test and H.pylori culture were negative,but Giemsa staining of biopsies revealed tightly coiled bacteria that immunostained with anti-H.pylori antibody.Sequencing of SH9 16S rRNA and the partial urease A and B subunit genes showed that the former sequence had highest similarity(99%;1302/1315 bp)to Helicobacter heilmannii(H.heilmannii)sensu stricto(H.heilmannii s.s.)BC1 obtained from a bobcat,while the latter sequence confirmed highest similarity(98.3%;1467/1493 bp)to H.heilmannii s.s.HU2 obtained from a human.The patient was diagnosed with multiple gastric ulcers associated with H.heilmannii s.s.infection.After triple therapy(amoxicillin,clarithromycin,and lansoprazole)with regimen for eradicating H.pylori,gastroscopy showed ulcer improvement and no H.heilmannii s.s.upon biopsy.Takehisa Matsumoto Masatomo Kawakubo Taiji Akamatsu Naohiko Koide Naoko Ogiwara Seiko Kubota Mitsutoshi Sugano Yoshiyuki Kawakami Tsutomu Katsuyama Hiroyoshi Ota 2014World Journal of Gastroenterology2014,20,12:4
10MK-0626,a selective DPP-4 inhibitor,attenuates hepatic steatosis in ob/ob mice显示文摘AIM:To investigate the mechanism and in vivo effects of MK-0626,a dipeptidyl peptidase-4 inhibitor,on hepatic steatosis using ob/ob mice.METHODS:We analyzed obese(ob/ob)8-wk-old male mice that had been randomly divided into two groups of ob/ob mice(n=16 each)and were treated with1.5 or 3 mg/kg MK-0626 and two control groups of untreated ob/ob mice and lean littermates(n=16 each).All mice were fed a normal chow diet with or without MK-0626 for either four or eight weeks.Blood samples were collected,and total hepatectomy was performed.RESULTS:The administration of dietary MK-0626 ameliorated the hepatic lipid accumulation in ob/ob micetreated with 3 mg/kg MK-0626(3 MK),P<0.05,vs untreated ob/ob mice(ob/ob).The MK-0626 treatment reduced the serum alanine aminotransferase levels(both treatment groups,P<0.05 vs ob/ob)and glucoses/insulin levels/calculated HOMA scores(1.5 MK,P<0.05vs ob/ob;3 MK,P<0.01 vs ob/ob)and increased the serum adiponectin levels(3 MK,P<0.05 vs ob/ob)in a dose-dependent manner.The MK-0626 treatment increased the m RNA expression of peroxisome proliferator-activated receptorα/microsomal triglyceride transfer protein(1.5 MK,P<0.05 vs ob/ob;3 MK,P<0.01vs ob/ob)but reduced the sterol regulatory element binding transcription factor-1c/fatty acid synthase/stearoyl-Co A desaturase-1(both treatment groups,P<0.01 vs ob/ob).The MK-0626 treatment increased the activity of AMP-activated protein kinase(AMPK)(both treatment groups,P<0.01 vs ob/ob).CONCLUSION:MK-0626 could attenuate hepatic steatosis through enhancing AMPK activity,inhibiting hepatic lipogenic gene expression,enhancing triglyceride secretion from liver and increasing serum adiponectin levels.Tatsuya Ohyama Ken Sato Yuichi Yamazaki Hiroaki Hashizume Norio Horiguchi Satoru Kakizaki Masatomo Mori Motoyasu Kusano Masanobu Yamada 2014World Journal of Gastroenterology2014,20,43:4
11Reduction of virus burden-induced splenectomy in patients with liver cirrhosis related to hepatitis C virus infection显示文摘瞄准:检验丙肝病毒(HCV ) 在在脾切除术以后的肝脏硬化症的病人的层次和免疫学的标记。方法:HCV RNA 乳头 ers 以及细胞、体液的有免疫力的标记与一口未经触动的怒气在脾切除术以后并且在 32 肝脏硬化症的控制在 20 个肝脏硬化症的病人被决定。结果:浆液 HCV RNA 乳头 ers 比在控制在 splenectomized 病人是更低的(186+/-225 x 10 (3 ) copies/mL 对 541+/-417 x 10 (3 ) copies/mL, P<0.01 ) 。HCV RNA 被判定到自发地控制在 4 个 splenectomized 病人,但是在没有被根除了。自然漂亮房间活动比在控制在 splenectomized 病人是更高的(41.2+/-19.3% 对 24.7+/-15.3% , P<0.01 ) ,并且除了在那些,自然漂亮房间活动否定地与血清型 2-related 感染在 splenectomized 病人被相关到 HCV RNA 乳头 ers。CD4/CD8 比率比在控制在 splenectomized 病人是显著地更低的。结论:调查结果建议那脾切除术可以减少在有 HCV 感染的肝脏硬化症的病人的病毒负担至少部分地,通过自然漂亮房间活动的扩大。Tetsuro Sekiguchi Takeaki Nagamine Hitoshi Takagi Masatomo Mori 2006World Journal of Gastroenterology2006,12,13:4
12Small invasive ductal carcinoma of the pancreas distinct from branch duct intraductal papillary mucinous neoplasm显示文摘Endoscopic ultrasonography(EUS)is a highly sensitive diagnostic method for the detection of small pancreatic carcinomas.Recently,there have been some reports describing the utility of contrast-enhanced harmonic EUS(CEH-EUS)which uses sonographic contrast agent for differentiation of a pancreatic mass.This report describes a case of small adenocarcinoma of the pancreas distinct from branch duct intraductal papillary mucinous neoplasm(IPMN)in which investigation by EUS took place every 6 mo and diagnosis was made accurately by additional CEH-EUS during the follow- up of the branch duct IPMN.A 68-year-old female was admitted to our hospital because of a branch duct IPMN in the pancreatic body.She had been followedup by EUS every 6 mo.However,after 2 years EUSdemonstrated a low echoic area distinct from the branch duct IPMN which was vaguely discernible by EUS,and accurate sizing and differential diagnosis were considered difficult on the EUS imaging.CHEUS with Sonazoid revealed a hypovascular tumor and we suspected small pancreatic carcinoma.The histopathological diagnosis was adenocarcinoma (10 mm)in the pancreatic tail,distinct from the branch duct IPMN of the pancreatic body.EUS and CEH-EUS may play an important role in the correct diagnosis of small pancreatic tumors,including synchronous and metachronous occurrence of IPMN and ductal adenocarcinoma of the pancreas.Hiroki Sakamoto Masayuki Kitano Takamitsu Komaki Hajime Imai Ken Kamata Masatomo Kimura Yoshifumi Takeyama Masatoshi Kudo 2009World Journal of Gastroenterology2009,15,43:2

14Overexpression of NK2 inhibits liver regeneration after partial hepatectomy in mice显示文摘AIM: To investigate the in vivo effects of NK2 on liver regeneration after partial hepatectomy (PH). METHODS: Survival after PH was observed with 21 NK2 transgenic mice and 23 wild-type (WT) mice over 10 d. Liver regeneration was analyzed using histology and immunohistochemistry. Expressions of genes were analyzed using Northern blot analysis, immunoprecipitation and immunoblotting, and reverse transcriptase polymerase chain reaction assay. KaplanMeier method and the log-rank test were used for ahalyzing the survival after PH. Differences in the resultsof immunohistochemistry and percentage of liver regeneration was determined by the Student's t-test. RESULTS: More than half of NK2 transgenic mice died within 48 h after PH. After PH, increased deposition of small lipid droplets in hepatocytes was evident and hepatic proliferation was inhibited in NK2 transgenic mice. The hepatic expression and kinase activity of HGF receptor, c-Met, were unchanged among WT mice and NK2 transgenic mice after PH. The expression of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in liver tissues were prolonged in NK2 transgenic mice that died after PH.CONCLUSION: Our findings indicate that overexpression of NK2 inhibits liver regeneration after PH.Toshiyuki Otsuka Norio Horiguchi Daisuke Kanda Takashi Kosone Yuichi Yamazaki Kazuhisa Yuasa Naondo Sohara Satoru Kakizaki Ken Sato Hitoshi Takagi Glenn Merlino Masatomo Mori 2005World Journal of Gastroenterology2005,11,47:2
15Clinical characteristics of null responders to Peg-IFNα2b/ ribavirin therapy for chronic hepatitis C显示文摘AIM: To predict which chronic hepatitis C patients are likely to be late-responders, we herein investigated the clinical characteristics of null-responders at 36 wk with hepatitis C virus (HCV) genotype Ib and a high viral load during the course of pegylated interferon (Peg-IFN)/ ribavirin ther apy. METHODS: One hundred forty-two patients with genotype Ib HCV and a high viral load were included in this study. Peg-IFNα2b (1.5 μg/kg once a week) and ribavirin (600-1000 mg per day according to body weight) were administered for 48 wk. We def ined nullresponders as the cases that never cleared serum HCV RNA as determined using RT-PCR until 36 wk. Other patients were def ined as responders. We compared the clinical characteristics (age, gender, body mass index, previous treatment) and HCV RNA titer during the therapy between null-responders and responders.RESULTS: The HCV RNA clearance rate was 17.9% (24/134), 46.3% (62/134), 60.6% (86/142), 86.6% (123/142), and 88.0% (125/142) at 4, 8, 12, 24, and 36 wk, respectively. There were 17 patients (12.0%) who were still null-responders at 36 wk. There were no differences in the clinical characteristics between the responders and null-responders except for the titer and decline rates of HCV RNA at 1 wk and 4 wk. The HCV RNA titers at 1 wk and after 4 wk of treatment were significantly higher in the null-responders in comp arison to the responders (P <0.01). The serum HCV RNA titers of the responders decreased by 1.3 log after 1 wk of treatment, and 1.6 log after 4 wk of treatm ent, respectively. On the other hand, the titers of the null responders decreased by only 0.5 log after 1 wk, and 0.7 log after 4 wk of treatment, respectively. The decrease rates of HCV RNA after 1 and 4 wk of treatm ent were signif icantly worse for null responders than for the responders (P <0.01). CONCLUSION: The HCV RNA titer at 1 wk and 4 wk after initiating treatment may be useful for predicting null-responders to Peg-IFNα2b/ribavirin therapy. However, further investigation is needed to determine the optimal time at which the decision to discontinue the Peg-IFNα2b/ribavirin therapy for null-responders can be made.Hideyuki Suzuki Satoru Kakizaki Norio Horiguchi Takeshi Ichikawa Ken Sato Hitoshi Takagi Masatomo Mori 2010World Journal of Hepatology2010,2,11:2
16Study on control of rock fragmentation at limestone quarry显示文摘The size distribution of a muck pile depends not on only the blasting standard but also on the mechanical properties,joint system,and crack density of the rock mass. As,the cracks in the rock masses are especially heavily developed at the limestone quar- ries in Japan,they,along with the joints,have a large impact on the effects of blasting, such as the size of the muck pile.Therefore,if the joint system and/or crack density in a rock mass can be determined and quantitatively evaluated,the blasting operation can be conducted more effectively,efficiently and safely.However,guidelines for designing ap- propriate blasting standards based on the rock mass conditions have not yet been scien- tifically developed.Therefore,blasting tests were conducted on different mines and faces, under different geological conditions and blasting standards,in order to determine the im- pacts of each factor on the effects of blasting.Summarized the results of a series of blast- ing tests and described the impacts of geological conditions on the size of the muck pile produced by blast.SASAOKA Takashi SHIMADA Hideki SASAKI Takayuki ICHINOSE Masatomo MATSUI Kikuo 2008Journal of Coal Science & Engineering(China)2008,14,3:2
