| 1 | Transcriptional silencing of Dickkopf gene family by CpG island hypermethylation in human gastrointestinal cancer显示文摘AIM: To clarify alterations of Dickkopfs (Dkks) and Kremen2 (Krm2) in gastrointestinal cancer. METHODS: We investigated the expression profiles and epigenetic alterations of Dkks and Krm2 genes in gastrointestinal cancer using RT-PCR, tissue microarray analysis, and methylation specific PCR (MSP). Cancer cells were treated with the demethylating agent and/or histone deacetylase inhibitor. WST-8 assays and in vitro invasion assays after treatment with specific siRNA for those genes were performed. RESULTS: Dkks and Krm2 expression levels were reduced in a certain subset of the gastrointestinal cancer cell lines and cancer tissues. This was correlated with promoter hypermethylation. There were significant correlations between Dkks over-expression levels and beta-catenin over-expression in colorectal cancer. In colorectal cancers with beta-catenin over-expression, Dkk-1 expression levels were significantly lower in those with lymph node metastases than in those without. Down-regulation of Dkks expression by siRNA resulted in a significant increase in cancer cell growth and invasiveness in vitro.CONCLUSION: Down-regulation of the Dkks associated to promoter hypermethylation appears to be frequently involved in gastrointestinal tumorigenesis. | Tadateru Maehata Hiroaki Taniguchi Hiroyuki Yamamoto Katsuhiko Nosho Yasushi Adachi Nobuki Miyamoto Chie Miyamoto Noriyuki Akutsu Satoshi Yamaoka Fumio Itoh | 2008 | World Journal of Gastroenterology2008，14，17： | 19 |
| 2 | Pancreatic neuroendocrine tumor and solid-pseudopapillary neoplasm: Key immunohistochemical profiles for differential diagnosis显示文摘AIM To reveal better diagnostic markers for differentiating neuroendocrine tumor(NET) from solid-pseudopapillary neoplasm(SPN), focusing primarily on immunohistochemical analysis.METHODS We reviewed 30 pancreatic surgical specimens of NET(24 cases) and SPN(6 cases). We carried out comprehensive immunohistochemical profiling using 9 markers: Synaptophysin, chromogranin A, pancytokeratin, E-cadherin, progesterone receptor,vimentin, α-1-antitrypsin, CD10, and β-catenin.RESULTS E-cadherin staining in NETs, and nuclear labeling of β-catenin in SPNs were the most sensitive and specific markers. Dot-like staining of chromogranin A might indicate the possibility of SPNs rather than NETs. The other six markers were not useful because their expression overlapped widely between NETs and SPNs. Moreover, two cases that had been initially diagnosed as NETs on the basis of their morphological features, demonstrated SPN-like immunohistochemical profiles. Careful diagnosis is crucial as we actually found two confusing cases showing disagreement between the tumor morphology and immunohistochemical profiles.CONCLUSION E-cadherin, chromogranin A, and β-catenin were the most useful markers which should be employed for differentiating between NET and SPN. | Yusuke Ohara Tatsuya Oda Shinji Hashimoto Yoshimasa Akashi Ryoichi Miyamoto Tsuyoshi Enomoto Kaishi Satomi Yukio Morishita Nobuhiro Ohkohchi | 2016 | World Journal of Gastroenterology2016，22，38： | 19 |
| 3 | Combined assessment of myocardial damage and electrical disturbance in chronic heart failure显示文摘AIM To investigate feasibility of combined assessment of biochemical and electrophysiological myocardial impairment markers risk-stratifying patients with chronic heart failure(CHF). METHODS Serum levels of heart-type fatty acid binding protein(H-FABP) as a marker of ongoing myocardial damage and QRS duration on electrocardiogram were measured at admission in 322 consecutive patients with CHF. A prolonged QRS duration was defined as 120 ms or longer. The cut-off value for H-FABP level(4.5 ng/mL) was determined from a previous study. Patients were prospectively followed during a median follow up period of 534 d. The primary endpoint was cardiac deaths and rehospitalization for worsening CHF.RESULTS There were 117 primary events, including 27 cardiac deaths and 90 rehospitalizations. Patients were stratified into four groups according to H-FABP level and QRS duration(≥ 120 ms). Multivariate analysis demonstrated that high H-FABP levels [hazard ratio(HR) = 1.745, P = 0.021] and QRS prolongation(HR1.612, P = 0.0258) were independent predictors of cardiac events. Kaplan-Meier analysis demonstrated that the combination of high H-FABP levels and QRS prolongation could be used to reliably stratify patients at high risk for cardiac events(log rank test P < 0.0001).CONCLUSION Combined assessment of myocardial damage and electrical disturbance can be used to risk-stratify patients with CHF. | Shinpei Kadowaki Tetsu Watanabe Yoichiro Otaki Taro Narumi Yuki Honda Hiroki Takahashi Takanori Arimoto Tetsuro Shishido Takuya Miyamoto Isao Kubota | 2017 | World Journal of Cardiology2017，9，5： | 14 |
| 4 | Pathologic complete response confirmed by surgical resection for liver metastases of gastrointestinal stromal tumor after treatment with imatinib mesylate显示文摘A 39-year-old male underwent distal gastrectomy for a high grade gastrointestinal stromal tumor(GIST) . Computed tomography(CT) and magnetic resonance imaging(MRI) 107 mo after the operation,revealed a cystic mass(14 cm in diameter) and a solid mass(9 cm in diameter) in the right and left lobes of the liver,respectively. A biopsy specimen of the solid mass showed a liver metastasis of GIST. The patient received imatinib mesylate(IM) treatment,400 mg/day orally. Following the IM treatment for a period of 35 mo,the patient underwent partial hepatectomy(S4 + S5) . The effect of IM on the metastatic lesions was interpreted as pathologic complete response(CR) . Pathologically verified cases showing therapeutic efficacy of IM have been rarely reported. | Seiji Suzuki Koji Sasajima Masayuki Miyamoto Hidehiro Watanabe Tadashi Yokoyama Hiroshi Maruyama Takeshi Matsutani Aimin Liu Masaru Hosone Shotaro Maeda Takashi Tajiri | 2008 | World Journal of Gastroenterology2008，14，23： | 11 |
| 5 | Management of chronic disruption of the distal tibiofibular syndesmosis显示文摘Disruption of the distal tibiofibular syndesmosis is frequently accompanied by rotational ankle fracture such as pronation-external rotation and rarely occurs without ankle fracture.In such injury,not only inadequately treated or misdiagnosed cases,but also correctly diagnosed cases can possibly result in a chronic pattern which is more troublesome to treat than an acute pattern.This paper reviews anatomical and biomechanical characteristics of the distal tibiofibular joint,the mechanism of chronic disruption of the distal tibiofibular syndesmosis,radiological and arthroscopic diagnosis,and surgical treatment. | Wataru Miyamoto Masato Takao | 2011 | World Journal of Orthopedics2011，2，1： | 11 |
| 6 | Aluminum potassium sulfate and tannic acid sclerotherapy for Goligher Grades Ⅱ and Ⅲ hemorrhoids: Results from a multicenter study显示文摘AIM: To show that aluminum potassium sulfate and tannic acid(ALTA) sclerotherapy has a high success rate for Grade Ⅱ and Ⅲ hemorrhoids.METHODS: This study was based on the clinical data of 604 patients with hemorrhoids who underwent ALTA sclerotherapy between January 2009 and February 2015. The objective of this study was to assess the efficacy of this treatment for Grades Ⅱ and Ⅲ hemorrhoids. Preoperative and postoperative symptoms, complications and success rate were all assessed retrospectively. Follow-up consisted of a simple questionnaire, physical examination and an anoscopy. Patients were followed-up at one day, one week, two weeks, one month, one year, two years, three years, four years and five years after the ALTA sclerotherapy.RESULTS: One hundred and sixty-nine patients were diagnosed with Grade Ⅱ hemorrhoids and 435 patients were diagnosed with Grade Ⅲ hemorrhoids. The one year, three year and five year cumulative success rates of ALTA sclerotherapy for Grades Ⅱ and Ⅲ hemo-rrhoids were 95.9% and 93.1%; 89.3% and 83.7%; and 89.3% and 78.2%, respectively. No significant differences were observed in the cumulative success rates after ALTA sclerotherapy between Grades Ⅱ and Ⅲ hemorrhoids(P = 0.09). There were forty-seven post-operative complications(low grade fever; anal pain; urinary retention; rectal ulcer; and others). No serious or life-threatening complications occurred and all cases improved through conservative treatment. At univariate analysis there were no predictive factors of failure.CONCLUSION: ALTA sclerotherapy has had a high success rate for Grade Ⅱ and Ⅲ hemorrhoids during five years of post-operative treatment. However, additional studies are needed to evaluate the efficacy of this ALTA sclerotherapy in the management of hemorrhoidal disease. | Hidenori Miyamoto Takenori Hada Gentaro Ishiyama Yoshito Ono Hideo Watanabe | 2016 | World Journal of Hepatology2016，8，20： | 10 |
| 7 | Axonal remodeling in the corticospinal tract after stroke: how does rehabilitative training modulate it?显示文摘Stroke causes long-term disability, and rehabilitative training is commonly used to improve the consecutive functional recovery. Following brain damage, surviving neurons undergo morphological alterations to reconstruct the remaining neural network. In the motor system, such neural network remodeling is observed as a motor map reorganization. Because of its significant correlation with functional recovery, motor map reorganization has been regarded as a key phenomenon for functional recovery after stroke. Although the mechanism underlying motor map reorganization remains unclear, increasing evidence has shown a critical role for axonal remodeling in the corticospinal tract. In this study, we review previous studies investigating axonal remodeling in the corticospinal tract after stroke and discuss which mechanisms may underlie the stimulatory effect of rehabilitative training. Axonal remodeling in the corticospinal tract can be classified into three types based on the location and the original targets of corticospinal neurons, and it seems that all the surviving corticospinal neurons in both ipsilesional and contralesional hemisphere can participate in axonal remodeling and motor map reorganization. Through axonal remodeling, corticospinal neurons alter their output selectivity from a single to multiple areas to compensate for the lost function. The remodeling of the corticospinal axon is influenced by the extent of tissue destruction and promoted by various therapeutic interventions, including rehabilitative training. Although the precise molecular mechanism underlying rehabilitation-promoted axonal remodeling remains elusive, previous data suggest that rehabilitative training promotes axonal remodeling by upregulating growth-promoting and downregulating growth-inhibiting signals. | Naohiko Okabe Kazuhiko Narita Osamu Miyamoto | 2017 | Neural Regeneration Research2017，12，2： | 8 |

| 9 | Transcatheter arterial chemoembolization with a fine-powder formulation of cisplatin for hepatocellular carcinoma显示文摘AIM:To evaluate the efficacy of transcatheter arterial chemoembolization(TACE) using a suspension of a fine-powder formulation of cisplatin(DDPH) for hepatocellular carcinoma(HCC).METHODS:The study population was comprised of 164 patients who were treated by TACE alone.Of these patients,76 underwent TACE using a suspension of DDPH in lipiodol(LPD)(DDPH group),and the remaining 88 underwent TACE with an emulsion of doxorubicin(ADM) with LPD(ADM group).We compared the DDPH group with the ADM group in terms of the objective early response rate,progression free survival(PFS) and overall survival(OS).RESULTS:The objective early response rate in the DDPH group was significantly higher than that in the ADM group(54% vs 24%,P < 0.001).The PFS rate in the DDPH group was also significantly higher than that in the ADM group(P < 0.001).Moreover,the OS in the DDPH group was significantly longer than that in the ADM group(P = 0.002).Although the incidence rate of nausea or vomiting in the DDPH group was higher than that in the ADM group,the ADM group showed a higher incidence rate of the adverse events of hepatic arterial damage and leucopenia.No other serious complications were observed in either group.CONCLUSION:We conclude that TACE using a suspension of DDPH in LPD could be a useful treatment for HCC. | Kazuhiro Kasai Akira Ushio Kei Sawara Yasuhiro Miyamoto Yukiho Kasai Kanta Oikawa Hidekatsu Kuroda Yasuhiro Takikawa Kazuyuki Suzuki | 2010 | World Journal of Gastroenterology2010，16，27： | 6 |
| 10 | Three-dimensional imaging identified the accessory bile duct in a patient with cholangiocarcinoma显示文摘The development of diagnostic imaging technology, such as multidetector computed tomography(MDCT) and magnetic resonance cholangiopancreatography(MRCP), has made it possible to obtain detailed images of the bile duct. Recent reports have indicated that a 3-dimensional(3D) reconstructed imaging system would be useful for understanding the liver anatomy before surgery. We have investigated a novel method that fuses MDCT and MRCP images. This novel system easily made it possible to detect the anatomical relationship between the vessels and bile duct in the portal hepatis. In this report, we describe a very rare case of extrahepatic cholangiocarcinoma associated with an accessory bile duct from the caudate lobe connecting with the intrapancreatic bile duct. We were unable to preoperatively detect this accessory bile duct using MDCT and MRCP. However, prior to the second operation, we were able to clearly visualise the injured accessory bile duct using our novel 3D imaging modality. In thisreport, we suggest that this imaging technique can be considered a novel and useful modality for understanding the anatomy of the portal hepatis, including the hilar bile duct. | Ryoichi Miyamoto Yukio Oshiro Shinji Hashimoto Keisuke Kohno Kiyoshi Fukunaga Tatsuya Oda Nobuhiro Ohkohchi | 2014 | World Journal of Gastroenterology2014，20，32： | 6 |
| 11 | Grey-scale sonography and sonoelastography for diagnosing carpal tunnel syndrome显示文摘Carpal tunnel syndrome(CTS) is a common peripheral entrapment neuropathy of the median nerve at wrist level, and is thought to be caused by compression of the median nerve in the carpal tunnel. There is no standard quantitative reference for the diagnosis of CTS. Greyscale sonography and sonoelastography(SEL) have been used as diagnostic tools. The most commonly agreed findings in grey-scale sonography for the diagnosis of CTS is enlargement of the median nerve cross-sectional area(CSA). Several authors have assessed additional parameters. 'Delta CSA' is the difference between the proximal median nerve CSA at the pronator quadratus and the maximal CSA within the carpal tunnel. The 'CSA ratio' is the ratio of CSA in the carpal tunnel to the CSA at the mid forearm. These additional parameters showed better diagnostic accuracy than CSA measurement alone. Recently, a number of studies have investigated the elasticity of the median nerve using SEL, and have shown that this also has diagnostic value, as it was significantly stiffer in CTS patients compared to healthy volunteers. In this review, we summarize the usefulness of grey-scale sonography and SEL in diagnosing CTS. | Hideaki Miyamoto Yutaka Morizaki Takahiro Kashiyama Sakae Tanaka | 2016 | World Journal of Radiology2016，8，3： | 5 |

| 13 | Petrology and SHRIMP zircon geochronology of granulites from Vesleknausen, Lützow-Holm Complex, East Antarctica: Neoarchean magmatism and Neoproterozoic high-grade metamorphism显示文摘We report new petrological data and geochronological measurements of granulites from Vesleknausen in the highest-grade section of the Lützow-Holm Complex, part of the Gondwana-assembling collisional orogen in East Antarctica. The locality is dominated by felsic to intermediate orthogneiss(charnockite and minor biotite gneiss), mafic orthogneiss, and hornblende-pyroxene granulite, with deformed and undeformed dykes of metagranite and felsic pegmatite. Pseudosection analysis of charnockite in the system NCKFMASHTO, supported by geothermometry of mafic orthogneiss, was used to infer peak metamorphic temperatures of 750-850 ℃, approximately 150 ℃ lower than those estimated for metasedimentary gneisses from Rundvagshetta, 6 km to the northeast. SHRIMP U-Pb analysis of zircons from feldspar-pyroxene gneiss, which corresponds to a partially molten patch around mafic orthogneiss,yielded a Concordia upper intercept ages of 2507.9 7.4 Ma, corresponding to the time of formation of the magmatic protolith to the orthogneiss. Partial melting during peak metamorphism probably took place between 591 and 548 Ma, as recorded in rims overgrew around magmatic zircon. Our results suggest that Rundvagshetta-Vesleknausen-Strandnibba region in southwestern Lützow-Holm Bay, where orthogneisses are dominant, consists of a single crustal block, possibly formed by ca. 2.5 Ga arc magmatism. The Neoarchean magmatic terrane was tectonically mingled with other fragments(such as metasedimentary units in northern Lützow-Holm Bay) by subduction/collision events during the assembly of Gondwana supercontinent, and subsequently underwent w850 C granulite-facies metamorphosed during Neoproterozoic to Cambrian final collisional event. | Toshiaki Tsunogae Daniel J.Dunkley Kenji Horie Takahiro Endo Tomoharu Miyamoto Mutsumi Kato | 2014 | Geoscience Frontiers2014，5，2： | 5 |
| 14 | A review on glass welding by ultra-short laser pulses显示文摘Glass welding by ultra-short pulsed(USP)lasers is a piece of technology that offers high strength joints with hermetic sealing.The joints are typically formed in glass that is transparent to the laser by exploiting nonlinear absorption effects that occur under extreme conditions.Though the temperature reached during the process is on the order of a few 1000°C,the heat affected zone(HAZ)is confined to only tens of micrometers.It is this controlled confinement of the HAZ during the joining process that makes this technology so appealing to a multitude of applications because it allows the foregoing of a subsequent tempering step that is typically essential in other glass joining techniques,thus making it possible to effectively join highly heat sensitive components.In this work,we give an overview on the process,development and applications of glass welding by USP lasers. | Kristian Cvecek Sarah Dehmel Isamu Miyamoto Michael Schmidt | 2019 | International Journal of Extreme Manufacturing2019，1，4： | 5 |
| 15 | CA19-9 level determines therapeutic modality in pancreatic cancer patients with para-aortic lymph node metastasis显示文摘Background: In general, para-aortic lymph node(LN16) metastasis has been considered as a contraindication for pancreatic resection. However, some pancreatic cancer patients with LN16 metastasis have been reported to survive for longer than expected after pancreatectomy. The purpose of this study was to determine whether pancreatic cancer patients with LN16 metastasis might benefit from surgery.Methods: We retrospectively reviewed 201 consecutive patients with invasive pancreatic ductal adenocarcinoma who underwent surgery at Osaka National Hospital between April 2003 and December 2012.These patients included 22 patients with LN16 metastasis who underwent an extended lymphadenectomy and 25 patients who underwent a palliative surgical biliary and gastric bypass. The clinicopathological data and outcomes were evaluated using univariate and multivariate analyses.Results: The overall survival of the patients with LN16 metastasis was poorer than that of the LN16-negative patients(P = 0.0014). An overall survival analysis of the LN16-positive patients stratified according to the preoperative CA19-9 level showed a significant difference between patients with a low preoperative CA19-9 level(≤360 U/mL) and those with a high preoperative CA19-9 level(>360 U/mL)(P = 0.0301). No significant difference in overall survival of patients was observed between those with LN16 positivity and those who underwent bypass surgery. However, the overall survival of the LN16-positive patients with a CA19-9 level ≤360 U/mL(n = 11) was significantly higher than that of those who underwent bypass surgery(P = 0.0452).Conclusion: Surgical resection and extended lymphadenectomy remains an option for pancreatic cancer patients with LN16-positivity whose CA19-9 level is ≤360 U/mL. | Tadafumi Asaoka Atsushi Miyamoto Sakae Maeda Naoki Hama Masanori Tsujie Masataka Ikeda Mitsugu Sekimoto Shoji Nakamori | 2018 | Hepatobiliary & Pancreatic Diseases International2018，17，1： | 4 |
| 16 | Chemical Composition of the Essential Oil of Mastic Gum and their Antibacterial Activity Against Drug-Resistant Helicobacter pylori显示文摘Mastic gum is derived from the tree named Pistacia lentiscus that is grown only in Island Hios of Greek.Since Mastic was first reported to kill Helicobacter pylori(H.pylori)in 1998,there has been no further study to elucidate which component of mastic specifically shows the antimicrobial activity against H.pylori.In this study,we examined which component of mastic gum was responsible for anti-H.pylori activity.We prepared the essential oil of mastic gum and identified 20 constituents by GC–MS analysis.Ten standard components were assayed for anti-H.pylori activity,and it clarified that a-terpineol and(E)-methyl isoeugenol showed the anti-H.pylori activity against four different H.pylori strains that were established from patients with gastritis,gastric ulcer and gastric cancer.These components could be useful to overcome the drug-resistance H.pylori growth in stomach. | Tomofumi Miyamoto Tadayoshi Okimoto Michihiko Kuwano | 2014 | Natural Products and Bioprospecting2014，4，4： | 4 |
| 17 | Clinical outcomes of Clutch Cutter endoscopic submucosal dissection for older patients with early gastric cancer显示文摘AIM To evaluate the clinical outcome of endoscopic submucosal dissection using the Clutch Cutter(ESDCC) in older patients. METHODS We reviewed 232 consecutive patients with early gastric cancer who underwent ESDCC between June 2010 and February 2014 at Aso Iizuka Hospital. We divided patients into two groups according to age: Older patients(> 80 years, n = 64) and non-older patients(≤ 80 years, n = 168). We retrospectively compared the prevalence rates of pre-existing comorbidities, anticoagulant therapy, en bloc resection, mean duration of hospitalization, incidence of ESDCC-related complications, change in performance status(PS) before and after ESDCC, and financial cost of admission. RESULTS The older group comprised 64 patients with a mean age of 84.1 years, and the non-older group comprised 168 patients with a mean age of 69.5 years. Older patients had significantly more pre-existing comorbidities than did non-older patients, specifically heart disease(P < 0.05). The en bloc resection rate in non-older patients was significantly higher than that in older patients(100% vs 95.3%, P = 0.02). There were no significant differences between the older and non-older groups in the incidence of ESDCC-related complications(i.e., postoperative bleeding and perforation) and the post-ESDCC change in PS. There were also no significant differences between the older and non-older groups in the mean duration of hospitalization(11.4 and 10.7 d, respectively) and financial cost of admission(657040 JPY and 574890 JPY, respectively).CONCLUSION ESDCC has a good clinical outcome in older patients. | Yoshihiro Otsuka Kazuya Akahoshi Kayoko Yasunaga Masaru Kubokawa Junya Gibo Shigeki Osada Kayo Tokumaru Kazuaki Miyamoto Takao Sato Yuki Shiratsuchi Masafumi Oya Hidenobu Koga Eikichi Ihara Kazuhiko Nakamura | 2017 | World Journal of Gastrointestinal Oncology2017，9，10： | 4 |
| 18 | Pulmonary artery sarcoma successfully treated by right pneumonectomy after definitive diagnosis显示文摘Pulmonary artery sarcoma(PAS)is a rare and lethal neoplasm that is usually diagnosed during surgery or autopsy.Early diagnosis and radical surgical resection offer the only chance for survival.However,making a preoperative histopathological diagnosis is quite difficult.We encountered a 57-year-old woman presenting a PAS that mimicked a pulmonary thromboembolism.After confirming a definitive diagnosis using a catheter suction biopsy,we successfully performed a right pneumonectomy via a median sternotomy without cardiopulmonary bypass.Eighteen months after surgery,no recurrence was observed. | Ryuta Fukai Kyu Rokkaku Yoshihito Irie Takao Imazeki Yoshiaki Katada Hiroyoshi Watanabe Yoshihiko Ueda Hideaki Miyamoto Masayuki Chida | 2013 | World Journal of Clinical Oncology2013，4，4： | 4 |
| 19 | Scaffolds based therapy for osteochondral lesions of the talus:A systematic review显示文摘AIM To clarify the effectiveness of scaffold-based therapy for osteochondral lesions of the talus(OLT). METHODS A systematic search of MEDLINE and EMBASE databases was performed during August 2016 and updated in January 2017. Included studies were evaluated with regard to the level of evidence(LOE) and quality of evidence(QOE) using the Modified Coleman Methodology Score. Variable reporting outcome data, clinical outcomes, and the percentage of patients who returned to sport at previous level were also evaluated. RESULTS Twenty-eight studies for a total of 897 ankles were included; 96% were either LOE Ⅲ or Ⅳ. Studies were designated as either of poor or fair quality. There were 30 treatment groups reporting six different scaffold repair techniques: 13 matrix-induced autologous chondrocyte transplantation(MACT), nine bone marrow derived cell transplantation(BMDCT), four autologous matrixinduced chondrogeneis(AMIC), and four studies of other techniques. The categories of general demographics(93%) and patient-reported outcome data(85%) were well reported. Study design(73%), imaging data(73%), clinical variables(49%), and patient history(30%) were also included. The weighted mean American Orthopaedic Foot and Ankle Society(AOFAS) score at final follow-up was: 86.7 in MACT, 88.2 in BMDCT, and 82.3 in AMIC. Eight studies reported that a weighted mean of 68.3% ofpatients returned to a previous level of sport activity. CONCLUSION Scaffold-based therapy for OLT may produce favorable clinical outcomes, but low LOE, poor QOE, and variability of the data have confounded the effectiveness of this treatment. | Yoshiharu Shimozono Youichi Yasui Andrew W Ross Wataru Miyamoto John G Kennedy | 2017 | World Journal of Orthopedics2017，8，10： | 4 |
