1Nonalcoholic fatty liver disease is a novel predictor of cardiovascular disease显示文摘AIM:To clarify whether nonalcoholic fatty liver disease(NAFLD)increases the risk of cardiovascular disease.METHODS:We carried out a prospective observational study with a total of 1637 apparently healthy Japanese men and women who were recruited from a health check-up program.NAFLD was diagnosed by abdominal ultrasonography.The metabolic syndrome(MS)was defined according to the modified National Cholesterol Education Program(NCEP)ATP Ⅲ criteria.Five years after the baseline evaluations,the incidence of cardiovascular disease was assessed by a self-administered questionnaire.RESULTS:Among 1221 participants available for outcome analyses,the incidence of cardiovascular disease was higher in 231 subjects with NAFLD at baseline(5 coronary heart disease,6 ischemic stroke,and 1 cerebral hemorrhage)than 990 subjects without NAFLD(3 coronary heart disease,6 ischemic stroke,and 1 cerebral hemorrhage).Multivariate analyses indicated that NAFLD was a predictor of cardiovascular disease independent of conventional risk factors(odds ratio 4.12,95% CI,1.58 to 10.75,P = 0.004).MS was alsoindependently associated with cardiovascular events.But simultaneous inclusion of NAFLD and MS in a multivariate model revealed that NAFLD but not MS retained a statistically significant correlation with cardiovascular disease.CONCLUSION:Although both of them were predictors of cardiovascular disease,NAFLD but not MS retained a statistically significant correlation with cardiovascular disease in a multivariate model.NAFLD is a strong predictor of cardiovascular disease and may play a central role in the cardiovascular risk of MS.Masahide Hamaguchi Takao Kojima Noriyuki Takeda Chisato Nagata Jun Takeda Hiroshi Sarui Yutaka Kawahito Naohisa Yoshida Atsushi Suetsugu Takahiro Kato Junichi Okuda Kazunori Ida Toshikazu Yoshikawa 2007World Journal of Gastroenterology2007,13,10:55
2STAT6免疫组化染色有助于孤立性纤维性肿瘤的诊断显示文摘孤立性纤维性肿瘤(SFT)发生部位非常广泛,多数为良性,约10%的病例表现为侵袭性。根据组织学特征和CD34表达能够对大多数SYT病例做出准确诊断,但SFT组织学的多样性、偶尔出现意外的免疫表型可能对诊断造成困难。分子分析发现大多数良恶性SFTs均存在特异性NAB2-STAT6融合基因。但基因检测需要专门的设备,花费较高,无法常规应用。Yoshida A Tsuta K Ohno M 李慧明(摘译) 余英豪(审校) 2014临床与实验病理学杂志2014,30,5:41

4New methods for the management of gastric varices显示文摘Bleeding from gastric varices has been successfully treated by endoscopic modalities. Once the bleeding from the gastric varices is stabilized, endoscopic treatment and/or interventional radiology should be performed to eradicate varices completely. Partial splenic artery embolization is a supplemental treatment to prolong the obliteration of the veins feeding and/or draining the varices. The overall incidence of bleeding from gastric varices is lower than that from esophageal varices. No studies to date have defi nitively characterized the causal factors behind bleeding from gastric varices. The initial episodes of bleeding from esophageal varices or gastric varices without prior treatment may be at least partly triggered by a violation of the mucosal barrier overlying varices. This is especially likely in the case of varices of the fundus. In view of the high rate of hemostasis achieved among bleeding gastric varices, treatment should be administered in selective cases. Among untreated cases, steps to prevent gastric mucosal injury confer very important protection against gastric variceal bleeding.Hiroshi Yoshida Yasuhiro Mamada Nobuhiko Taniai Takashi Tajiri 2006World Journal of Gastroenterology2006,12,37:31
5Comparison between combination therapy of percutaneous ethanol injection and radiofrequency ablation and radiofrequency ablation alone for patients with hepatocellular carcinoma显示文摘AIM: In the present study, the characteristics of PEI-RFA treatment were further elucidated by analyzing the relationship between the volume of coagulated necrosis and the energy requirement for ablation or the amount of ethanol injected into HCC.METHODS: The volume of coagulated necrosis, total energy requirement and energy requirement for coagulation of per unit volume were examined in the groups of PEI-RFA and RFA alone using the Cool-tip RF system.RESULTS: The results showed that the volume of coagulated necrosis induced was significantly larger in PEI-RFA group than in routine RFA group, when the total energy administered was comparable in both groups.In PEI-RFA, enlargement of coagulated necrosis was admitted in 3 dimensions and the amount of energy requirement per unit volume of coagulated necrosis was negatively correlated with the amount of ethanol injected into HCC.CONCLUSION: These results suggest that, compared to RFA alone, PEI-RFA enables to induce comparable coagulated necrosis with smaller energy requirement, and that PEI-RFA is likely to be less invasive than RFA alone irrespective of inducing enhanced coagulated necrosis.Thus, simple prior injection of ethanol may make RFA treatment more effective and less invasive for the treatment of patients with HCC.Kazutaka Kurokohchi Seishiro Watanabe Tsutomu Masaki Naoki Hosomi Yoshiaki Miyauchi Takashi Himoto Yasuhiko Kimura Seiji Nakai Akihiro Deguchi Hirohito Yoneyama Shuhei Yoshida Shigeki Kuriyama 2005World Journal of Gastroenterology2005,11,10:29
6New methods for the management of esophageal varices显示文摘Bleeding from esophageal varices (EVs) is a catastrophic complication of chronic liver disease. Many years ago, surgical procedures such as esophageal transection or distal splenorenal shunting were the only treatments for EVs. In the 1970s, interventional radiology procedures such as transportal obliteration, left gastric artery embolization, and partial splenic artery embolization were introduced, improving the survival of patients with bleeding EVs. In the 1980s, endoscopic treatment, endoscopic injection sclerotherapy (EIS), and endoscopic variceal ligation (EVL), further contributed to improved survival. We combined IVR with endoscopic treatment or EIS with EVL. Most patients with EVs treated endoscopically required follow- up treatment for recurrent varices. Proper management of recurrent EVs can significantly improve patients’ quality of life. Recently, we have performed EVL at 2-mo (bimonthly) intervals for the management of EVs. Longer intervals between treatment sessions resulted in a higher rate of total eradication and lower rates of recurrence and additional treatment.Hiroshi Yoshida Yasuhiro Mamada Nobuhiko Taniai Takashi Tajiri 2007World Journal of Gastroenterology2007,13,11:30
7The Plant Vascular System: Evolution, Development and Functions显示文摘The emergence of the tracheophyte-based vascular system of land plantshad major impacts on the evolution of terrestrial biology, in general,through its role in facilitating the development of plants with increasedstature, photosynthetic output, and ability to colonize a greatly expandedrange of environmental habitats. Recently, considerable progress hasbeen made in terms of our understanding of the developmental andphysiological programs involved in the formation and function of theplant vascular system. In this review, we first examine the evolutionaryevents that gave rise to the tracheophytes, followed by analysis of thegenetic and hormonal networks that cooperate to orchestrate vasculardevelopment in the gymnosperms and angiosperms. The two essentialfunctions performed by the vascular system, namely the delivery of resources (water, essential mineralnutrients, sugars and amino acids) to the various plant organs and provision of mechanical support arenext discussed. Here, we focus on critical questions relating to structural and physiological propertiescontrolling the delivery of material through the xylem and phloem. Recent discoveries into the role ofthe vascular system as an effective long-distance communication system are next assessed in termsof the coordination of developmental, physiological and defense-related processes, at the whole-plantlevel. A concerted effort has been made to integrate all these new findings into a comprehensive pictureof the state-of-the-art in the area of plant vascular biology. Finally, areas important for future researchare highlighted in terms of their likely contribution both to basic knowledge and applications to primaryindustry.William J.

8Safe procedure in endoscopic submucosal dissection for colorectal tumors focused on preventing complications显示文摘Endoscopic submucosal dissection (ESD) is efficient for en bloc resection of large colorectal tumors. However, it has several technical difficulties, because the wall of the colon is thin and due to the winding nature of the colon. The main complications of ESD comprise postoperative perforation and hemorrhage, similar to endoscopic mucosal resection (EMR). In particular, the rate of perforation in ESD is higher than that in EMR. Perforation of the colon can cause fatal peritonitis. Endoscopic clipping is reported to be an efficient therapy for perforation. Most cases with perforation are treated conservatively without urgent surgical intervention. However, the rate of postoperative hemorrhage in ESD is similar to that in EMR. Endoscopic therapy including endoscopic clipping is performed and most of the cases are treated conservatively without blood transfusion. In blood examination, some degree of inflammation is detected after ESD. For the standardization of ESD, it is most important to decrease the rate of perforation. Adopting a safe strategy for ESD and a suitable choice of knife are both important waysof preventing perforation. Moreover, appropriate training and increasing experience can improve the endoscopic technique and can decrease the rate of perforation. In this review, we describe safe procedures in ESD to prevent complications, the complications of ESD and their management.Naohisa Yoshida Nobuaki Yagi Yuji Naito Toshikazu Yoshikawa 2010World Journal of Gastroenterology2010,16,14:27

10Relationship between testicular volume and testicular function: comparison of the Prader orchidometric and ultrasonographic measurements in patients with infertility显示文摘瞄准:为了评估在阴囊的功能和阴囊的体积之间的关系,由使用 Prader orchidometry 和 ultrasonography (美国) 决定由每个方法显示正常阴囊的功能的批评的阴囊的卷测量了。方法:全部的阴囊的体积(恰好正的左阴囊的体积) 与不孕在 397 个人在 794 个睾丸被测量(吝啬的年龄, 35.6 年) 用 Prader orchidometer 并且也由 ultrasonography。Ultrasonographic 阴囊的体积作为长度×宽度×高度×被计算 0.71。评估卷功能关系,病人们被划分成从在 10 mL 下面由每个方法代表全部的阴囊的体积的 5-mL 增长到 50 mL 或更多的 10 个组。结果:吝啬的全部的阴囊的体积分别地基于 Prader orchidometry 和美国是 36.8 mL 和 26.3 mL。精液体积,精子密度,全部的精子计数,全部的能动精子计数,和浆液 FSH, LH,和睾丸激素都显著地相关,全部的阴囊的体积由任何一个方法测量了。吝啬的精子密度在在有在由 orchidometry 或在由 ultrasonography 的 20 mL 下面的 35 mL 下面的全部的阴囊的体积的病人的 oligozoospermic 范围。吝啬的全部的精子计数由 ultrasonography 在有在由 orchidometry 或不到 20 mL 的 30 mL 下面的全部的阴囊的体积的病人是低于正常的。结论:ultrasonography 或 Prader orchidometry 测量的阴囊的体积与阴囊的功能显著地相关。然而,批评全部的阴囊的体积显示正常或将近正常的阴囊的功能用 ultrasonography 是到用 Prader orchidometer 和 20 mL 的 35 mL 的 30 mL。Prader orchidometry morphometrically 并且机能上地与美国相比过高估计阴囊的体积。Hideo Sakamoto Yoshio Ogawa Hideki Yoshida 2008Asian Journal of Andrology2008,10,2:25
11Recent advances in the surgical treatment of hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC) is the most common primary liver malignancy. The treatment of HCC is complex and complicated by the severity of associated chronic liver disease, the stage of HCC, and the clinical condition of the patient. Liver resection(LR) is one of the most efficient treatments for patients with HCC, with an expected 5-year survival of 38%-61% depending on the stage of the disease. Improved liver function assessment, increased understanding of segmental liver anatomy from advanced imaging studies, and surgical technical progress are important factors that have led to reduced mortality in patients with HCC. The indication for LR may be expanded due to emerging evidences from laparoscopic hepatectomies and combined treatments with newly developed chemotherapies. Liver transplantation(LT) is considered as an ideal treatment for removal of existing tumors and the injured/preneoplastic underlying liver tissue with impaired liver function and the risk of multicentric carcinogenesis that results from chronically injured liver. However, LT is restricted to patients with minimal risk of tumor recurrence under immunosuppression. The expansion of criteria for LT in HCC patients is still under trial and discussion. Limited availability of grafts, as well as the risk and the cost of transplantation have led to considerable interest in expansion of the donor pool, living donor-related transplantation, and combined treatment involving LR and LT. This highlight presents evidence concerning recent studies evaluating LR and LT in HCC patients. In addition, alternative therapies for the treatment of early stage tumors and the management of patients on transplant waiting lists are discussed.Zenichi Morise Norihiko Kawabe Hirokazu Tomishige Hidetoshi Nagata Jin Kawase Satoshi Arakawa Rie Yoshida Masashi Isetani 2014World Journal of Gastroenterology2014,20,39:24
12Single-incision laparoscopic cholecystectomy:Single institution experience and literature review显示文摘Single-incision laparoscopic surgery is a rapidly evolving field as a bridge between traditional laparoscopic surgery and natural orifice transluminal endoscopic surgery.We report one of the initial clinical experiences in Japan with this new technique.Four cases of gallbladder diseases were selected for this new technique.A single curved intra-umbilical 25-mm incision was made by pulling out the umbilicus.A 12-mm trocar was placed through an open approach,and the abdominal cavity was explored with a 10-mm semiflexible laparoscope.Two 5-mm ports were inserted laterally from the laparoscope port.A 2-mm mini-loop retractor was inserted to retract the fundus of the gallbladder.Dissection was performed using an electric cautery hook and an Endograsper roticulator.There were two women and two men with a mean age of 50.5 years(range:40-61 years).All procedures were completed successfully without any perioperative complications.In all cases,there was no need to extend the skin incision.Average operative time was 88.8 min.Postoperative follow-up didnot reveal any umbili-cal wound complication.Single-incision laparoscopic cholecystectomy is feasible and a promising alternative method as scarless abdominal surgery for the treatment of some patients with gallbladder disease.Yasumitsu Hirano Toru Watanabe Tsuneyuki Uchida Shuhei Yoshida Kanae Tawaraya Hideaki Kato Osamu Hosokawa 2010World Journal of Gastroenterology2010,16,2:23
13Pure laparoscopic hepatectomy for hepatocellular carcinoma with chronic liver disease显示文摘Pure laparoscopic hepatectomy is a less invasive procedure than conventional open hepatectomy for the resection of hepatic lesions. Increases in experiences with the technique, in combination with advances in technology, have promoted the popularity of pure laparoscopic hepatectomy. However, indications for usage and potential contraindications of the procedure remain unresolved. The characteristics and specific advantages of the procedure, especially for hepatocellular carcinoma(HCC) patients with chronic liver diseases,are reviewed and discussed in this paper. For cirrhotic patients with liver tumors, pure laparoscopic hepatectomy minimizes destruction of the collateral blood and lymphatic flow from laparotomy and mobilization, and mesenchymal injury from compression. Therefore, pure laparoscopic hepatectomy has the specific advantage of minimal postoperative ascites production that leads to lowering the risk of disturbance in water or electrolyte balance and hypoproteinemia. It minimizes complications that routinely trigger postoperative serious liver failure. Under adequate patient positioning and port arrangement, the partial resection of the liver in the area of subphrenic space, peri-inferior vena cava area or next to the attachment of retro-peritoneum is facilitated in pure laparoscopic surgery by providing good vision and manipulation in the small operative field.Furthermore, the features of reduced post-operative adhesion, good vision, and manipulation within the small area between the adhesions make this procedure safer in the context of repeat hepatectomy procedures.These improved features are especially advantageous for patients with liver cirrhosis and multicentric and/or metachronous HCCs.Zenichi Morise Norihiko Kawabe Jin Kawase Hirokazu Tomishige Hidetoshi Nagata Hisanori Ohshima Satoshi Arakawa Rie Yoshida Masashi Isetani 2013World Journal of Hepatology2013,5,9:21
14SMALL ORGAN SIZE 1 and SMALL ORGAN SIZE 2/DWARF AND LOW-TILLERING Form aComplex to Integrate Auxin and Brassinosteroid Signaling in Rice显示文摘尽管植物生长素和 brassinosteroid (BR ) synergistically 控制各种各样的植物回答,位于 auxin-BR 串音下面的分子的机制很好没被理解。我们以前识别了 SMOS1,一个调整植物生长素的 APETALA2 类型抄写因素,作为小机关的原因的基因缩放 1 (smos1 ) 被各种各样的机关的一种减少的最后的尺寸在米饭描绘的异种。在这研究,我们识别了另一 smos 异种, smos2,哪个表演与 smos1 难区分的显型。SMOS2 与以前报导的矮子和 LOW-TILLERING (DLT ) 相同,它编码涉及 BR 发信号的 GRAS 蛋白质。SMOS1 和 SMOS2/DLT 身体上交往合作地在酵母并且在米饭原子核提高 transcriptional transactivation 活动。一致地, OsPHI-1 的表示, SMOS1 的一个直接目标,当 SMOS1 和 SMOS2/DLT 蛋白质两个都是在米饭房间的现在时,仅仅是 upregulated。一起拿,我们的结果建议 SMOS1 和 SMOS2/DLT 在在米饭表明串音的 auxin-BR 上形成重点建筑群。Ko Hirano Hideki Yoshida Koichiro Aya Mayuko Kawamura Makoto Hayashi Tokunori Hobo Karma Sato-lzawa Hidemi Kitano Miyako Ueguchi-Tanaka Makoto Matsuoka 2017Molecular Plant2017,10,4:20
15Multicenter study of endoscopic preoperative biliary drainage for malignant distal biliary obstruction显示文摘AIM: To determine the optimal method of endoscopic preoperative biliary drainage for malignant distal biliary obstruction.METHODS: Multicenter retrospective study was conducted in patients who underwent plastic stent(PS) or nasobiliary catheter(NBC) placement for resectable malignant distal biliary obstruction followed by surgery between January 2010 and March 2012. Procedurerelated adverse events, stent/catheter dysfunction(occlusion or migration of PS/NBC, developmentof cholangitis, or other conditions that required repeat endoscopic biliary intervention), and jaundice resolution(bilirubin level < 3.0 mg/d L) were evaluated. Cumulative incidence of jaundice resolution and dysfunction of PS/NBC were estimated using competing risk analysis. Patient characteristics and preoperative biliary drainage were also evaluated for association with the time to jaundice resolution and PS/NBC dysfunction using competing risk regression analysis.RESULTS: In total, 419 patients were included in the study(PS, 253 and NBC, 166). Primary cancers included pancreatic cancer in 194 patients(46%), bile duct cancer in 172(41%), gallbladder cancer in three(1%), and ampullary cancer in 50(12%). The median serum total bilirubin was 7.8 mg/d L and 324 patients(77%) had ≥ 3.0 mg/d L. During the median time to surgery of 29 d [interquartile range(IQR), 30-39 d]. PS/NBC dysfunction rate was 35% for PS and 18% for NBC [Subdistribution hazard ratio(SHR) = 4.76; 95%CI: 2.44-10.0, P < 0.001]; the pig-tailed tip was a risk factor for PS dysfunction. Jaundice resolution was achieved in 85% of patients and did not depend on the drainage method(PS or NBC).CONCLUSION: PS has insufficient patency for preoperative biliary drainage. Given the drawbacks of external drainage via NBC, an alternative method of internal drainage should be explored.Naoki Sasahira Tsuyoshi Hamada Osamu Togawa Ryuichi Yamamoto Tomohisa Iwai Kiichi Tamada Yoshiaki Kawaguchi Kenji Shimura Takero Koike Yu Yoshida Kazuya Sugimori Shomei Ryozawa Toshiharu Kakimoto Ko Nishikawa Katsuya Kitamura Tsunao Imamura Masafumi Mizuide Nobuo Toda Iruru Maetani Yuji Sakai Takao Itoi Masatsugu Nagahama Yousuke Nakai Hiroyuki Isayama 2016World Journal of Gastroenterology2016,22,14:18
16Neoadjuvant treatment for esophageal squamous cell carcinoma显示文摘Squamous cell carcinoma and adenocarcinoma are types of esophageal cancer, one of the most aggressive malignant diseases. Since both histological types present entirely different diseases with different epidemiology, pathogenesis and tumor biology, separate therapeutic strategies should be developed against each type. While surgical resection remains the dominant therapeutic intervention for patients with operable esophageal squamous cell carcinoma(ESCC), alternative strategies are actively sought to reduce the frequency of post-operative local or distant disease recurrence. Such strategies are particularly sought in the preoperative setting. Currently, the optimal management of resectable ESCC differs widely between Western and Asian countries(such as Japan). While Western countries focus on neoadjuvant or definitive chemoradiotherapy, neoadjuvant chemotherapy followed by surgery is the standard treatment in Japan. Importantly, each country and region has established its own therapeutic strategy from the results of local randomized control trials. This review discusses the current knowledge, available data and information regarding neoadjuvant treatment for operable ESCC.Yoshifumi Baba Masayuki Watanabe Naoya Yoshida Hideo Baba 2014World Journal of Gastrointestinal Oncology2014,6,5:17
17Selection of appropriate endoscopic therapies for duodenal tumors: An open-label study, single-center experience显示文摘AIM:To determine an appropriate compartmentalization of endoscopic submucosal dissection(ESD)or endoscopic mucosal resection(EMR)for duodenal tumors.METHODS:Forty-six duodenal lesions(excluding papillary lesions)from 44 patients with duodenal tumors treated endoscopically between 2005 and 2013 were divided into the ESD and EMR groups for retrospective comparison and analysis.RESULTS:The mean age was 65±9 years(35-79years).There were 24 lesions from men and 22 from women.The lesions consisted of 6 early cancers,31adenomas and 9 neuroendocrine tumors.Lesion location was the duodenal bulb in 15 cases and the descending part of the duodenum in 31 cases.The most common macroscopic morphology was elevated type in 21 cases(45.6%).Mean tumor diameter was 11.9±9.7 mm(3-60 mm).Treatment procedure was ESD(15 cases)vs EMR(31 cases).The examined parameters in the ESD vs EMR groups were as follows:mean tumor diameter,12.9±14.3 mm(3-60 mm)vs 11.4 ±6.7 mm(4-25 mm);en bloc resection rate,86.7%vs 83.9%;complete resection rate,86.7%vs 74.2%;procedure time,86.5±63.1 min(15-217 min)vs 13.2±17.0 min(2-89 min)(P<0.0001);intraprocedural perforation,3 cases vs none(P=0.0300);delayed perforation,none in either group;postprocedural bleeding,1 case vs none;mean postoperative length of hospitalization,8.2±2.9 d(5-16 d)vs 6.1±2.0 d(2-12 d)(P=0.0067);recurrence,none vs 1 case(occurring at 7 mo postoperatively).CONCLUSION:ESD was associated with a longer procedure time and a higher incidence of intraprocedural perforation;EMR was associated with a lower rate of complete resection.Satohiro Matsumoto Yukio Yoshida 2014World Journal of Gastroenterology2014,20,26:17
18Clinical significance of type V_I pit pattern subclassification in determining the depth of invasion of colorectal neoplasms显示文摘AIM: To clarify whether subclassification of the type VI pit pattern on the basis of magnifying colonoscopy findings is useful in determining the type and depth of invasion of colorectal neoplasms.METHODS: We retrospectively analyzed 272 colorectal neoplasms (117 dysplasias and 155 submucosal invasive carcinomas; 228 patients) with a type V pit pattern [type VI, n = 202; type VN, n = 70 (Kudo and Tsuruta classification system)]. We divided lesions with a type VI pit pattern into two subclasses, mildly irregular lesions and severely irregular lesions, according to the prominent and detailed magnifying colonoscopy findings. We examined the relation between these two subclasses and histology/invasion depth.RESULTS: One hundred and four lesions (51.5%) were judged to be mildly irregular, and 98 lesions (48.5%) were judged to be severely irregular. Ninety-seven (93.3%) mildly irregular lesions showed dysplasias or submucosal invasion of less than 1000 μm (SM < 1000 μm). Fifty-five (56.1%) severely irregular lesions showed submucosal invasion equal to or deeper than 1000 μm (SM ≥ 1000 μm). Mild irregularity was found significantly more often in dysplasias or lesions with SM < 1000 μm than in lesions with SM ≥ 1000 μm (P < 0.01).CONCLUSION: Subclassification of the type VI pit pattern is useful for identifying dysplasias or lesions with SM < 1000 μm.Hiroyuki Kanao Shinji Tanaka Shiro Oka Iwao Kaneko Shigeto Yoshida Koji Arihiro Masaharu Yoshihara Kazuaki Chayama 2008World Journal of Gastroenterology2008,14,2:15
19棕榈藤的热软化:半纤维木素基质的影响显示文摘利用蠕变柔量实验检测 8种棕榈藤植物细胞壁的半纤维素木素基质 ,了解其对棕榈藤热软化影响。首先用乙醇 -苯准备提取的单体样本 ,随后是用在木材上使用的标准程序对藤细胞进行化学分析。结果显示为细胞壁是 4 2 %~ 5 3%α -纤维素 ,19%~ 2 7%半纤维素和 2 0 %~ 4 0 %木素。蠕变柔量实验表明 ,样品软化程度取决于热量的提供情况。提取的单体软化是在 70~ 85℃时开始的 ,全纤维素在 75~ 95℃时软化 ,而α -纤维素样品在 10 0℃时软化。 8种品种的热软化程度差异也被观测到。它们的差异取决于品种间半纤维素木素的比例的不同 :基质的容量越大 ,分子运动越剧烈。同时还注意到从提取的单体的原料到全纤维素再到α -纤维素样品在热软化中的还原性差异。它取决于基质的还原量 ,因为木素去除了。α -纤维素还有其它的运动。这些运动仅衍生于纤维素链中的晶体 -非晶体区域。物质的晶体越多 ,可观测的分子运动越小。Abasolo W.P.

20Correlation between hepatic blood flow and liver function in alcoholic liver cirrhosis显示文摘AIM:To elucidate the correlation between hepatic blood flow and liver function in alcoholic liver cirrhosis(AL-LC).METHODS:The subjects included 35 patients with ALLC(34 men,1 woman;mean age,58.9±10.7 years;median age,61 years;range:37-76 years).All patientswere enrolled in this study after obtaining written informed consent.Liver function was measured with tests measuring albumin(Alb),prothrombin time(PT),brain natriuretic peptide(BNP),branched amino acid and tyrosine ratio(BTR),branched chain amino acid(BCAA),tyrosine,ammonia(NH3),cholinesterase(Ch E),immunoreactive insulin(IRI),total bile acid(TBA),and the retention rate of indocyanine green 15 min after administration(ICG R15).Hepatic blood flow,hepatic arterial tissue blood flow(HATBF),portal venous tissue blood flow(PVTBF),and total hepatic tissue blood flow(THTBF)were simultaneously calculated using xenon computed tomography.RESULTS:PVTBF,HATBF and THTBF were 30.2±10.4,20.0±10.7,and 50.3±14.9 m L/100 m L/min,respectively.Alb,PT,BNP,BTR,BCAA,tyrosine,NH3,Ch E,IRI,TBA,and ICG R15 were 3.50±0.50 g/d L,72.0%±11.5%,63.2±56.7 pg/m L,4.06±1.24,437.5±89.4μmol/L,117.7±32.8μmol/L,59.4±22.7μg/d L,161.0±70.8 IU/L,12.8±5.0μg/d L,68.0±51.8μmol/L,and 28.6%±13.5%,respectively.PVTBF showed a significant negative correlation with ICG R15(r=-0.468,P<0.01).No significant correlation was seen between ICG 15R,HATBF and THTBF.There was a significant correlation between PVTBF and Alb(r=0.2499,P<0.05),and NH3 tended to have an inverse correlation with PVTBF(r=-0.2428,P=0.0894).There were also many significant correlations between ICG R15 and liver function parameters,including Alb,NH3,PT,BNP,TBA,BCAA,and tyrosine(r=-0.2156,P<0.05;r=0.4318,P<0.01;r=0.4140,P<0.01;r=0.3610,P<0.05;r=0.5085,P<0.001;r=0.4496,P<0.01;and r=0.4740,P<0.05,respectively).CONCLUSION:Our investigation showed that there is a close correlation between liver function and hepatic blood flow.Hideaki Takahashi Ryuta Shigefuku Yoshihito Yoshida Hiroki Ikeda Kotaro Matsunaga Nobuyuki Matsumoto Chiaki Okuse Shigeru Sase Fumio Itoh Michihiro Suzuki 2014World Journal of Gastroenterology2014,20,45:14
