| 1 | The adult human testis transcriptional cell atlas显示文摘Human adult spermatogenesis balances spermatogonial stem cell (SSC) self-renewal and differentiation,alongside complex germ cell-niche interactions,to ensure long-term fertility and faithful genome propagation. Here,we performed single-cell RNA sequencing of -6500 testicular cells from young adults. We found five niche/somatic cell types (Leydig,myoid,Sertoli,endothelial,macrophage),and observed germline-niche interactions and key human-mouse differences. Spermatogenesis,including meiosis,was reconstructed computationally,revealing sequential coding,non-coding,and repeat-element transcriptional signatures. Interestingly,we identified five discrete transcriptional/developmental spermatogonial states,including a novel early SSC state,termed State 0. Epigenetic features and nascent transcription analyses suggested developmental plasticity within spermatogonial States. To understand the or丨gin of State 0,we profiled testicular cells from infants,and identified distinct similarities between adult State 0 and infant SSCs. Overall,our datasets describe key transcriptional and epigenetic signatures of the normal adult human testis,and provide new insights into germ cell developmental transitions and plasticity. | Jingtao Guo Edward J.

| 2 | Prognosis of ulcerative colitis differs between patients with complete and partial mucosal healing, which can be predicted from the platelet count显示文摘AIM:To determine the difference in clinical outcome between ulcerative colitis(UC)patients with Mayo endoscopic subscore(MES)0 and those with MES 1.METHODS:UC patients with sustained clinical remission of 6 mo or more at the time of colonoscopy were examined for clinical outcomes and the hazard ratios of clinical relapse according to MES.Parameters,including blood tests,to identify predictive factors for MES 0and slight endoscopic recurrence in clinically stablepatients were assessed.Moreover,a receiver operating characteristic curve was generated,and the area under the curve was calculated to indicate the utility of the parameters for the division between complete and partial mucosal healing.All P values were two-sided and considered significant when less than 0.05.RESULTS:A total of 183 patients with clinical remission were examined.Patients with MES 0(complete mucosal healing:n=80,44%)were much less likely to relapse than those with MES 1(partial mucosal healing:n=89,48%)(P<0.0001,log-rank test),and the hazard ratio of risk of relapse in patients with MES 1 vs MES0 was 8.17(95%CI:4.19-17.96,P<0.0001).The platelet count(PLT)<26×104/μL was an independent predictive factor for complete mucosal healing(OR=4.1,95%CI:2.15-7.99).Among patients with MES 0 at the initial colonoscopy,patients of whom colonoscopy findings shifted to MES 1 showed significant increases in PLT compared to those who maintained MES 0(3.8×104/μL vs-0.6×104/μL,P<0.0001).CONCLUSION:The relapse rate differed greatly between patients with complete and partial mucosal healing.A shift from complete to partial healing in clinically stable UC patients can be predicted by monitoring PLT. | Asuka Nakarai Jun Kato Sakiko Hiraoka Toshihiro Inokuchi Daisuke Takei Yuki Moritou Mitsuhiro Akita Sakuma Takahashi Keisuke Hori Keita Harada Hiroyuki Okada Kazuhide Yamamoto | 2014 | World Journal of Gastroenterology2014，20，48： | 11 |
| 3 | 负载金催化剂上CO氧化反应活性与金属氧化物载体中金属-氧结合能之间的关系(英文)显示文摘讨论了金属氧化物载体(MO_x)对其负载纳米金催化剂(Au/MO_x)上CO氧化反应的影响.采用典型的共沉淀法和沉积-沉淀法在完全相同的焙烧条件下制备了一系列MO_x负载金催化剂,以CO氧化转化50%时的反应温度(T_(1/2))定量评价了MO_x载体和Au/MO_x催化剂的催化活性.进一步将MO_x载体与相应Au/MO_x催化剂的T_(1/2)值之差对MO_x载体的金属-氧结合能做曲线进行关联,发现二者呈明显的火山型关系.这一结果表明,采用具有适当金属-氧结合能(300–500 atom O)的MO_x可大大提高沉积于其上的Au纳米颗粒的催化活性. | Takashi Fujita Masanori Horikawa Takashi Takei Tom Murayama Masatake Haruta | 2016 | Chinese Journal of Catalysis2016，37，10： | 3 |
| 4 | Bronchial bleeding caused by recurrent pneumonia after radical esophagectomy for esophageal cancer显示文摘We herein report a case of bronchial bleeding afterradical esophagectomy that was treated with lobectomy.A 65-year-old male who underwent subtotal esophagectomy with three-field lymph node dissection for esophageal carcinoma was referred to our hospital because of sudden hemoptysis.After the esophagectomy,bilateral vocal cord paralysis was observed,and the patient suffered from repeated episodes of aspiration pneumonia.Bronchoscopy revealed hemosputum in the right middle lobe bronchus,and contrast-enhanced computed tomography showed tortuous arteries arising from the right inferior phrenic artery and left subclavian artery toward the right middle lobe bronchus.Although bronchial arterial embolization was performed twice to control the recurrent hemoptysis,the procedures were unsuccessful.Right middle lobectomy was therefore performed via video-assisted thoracic surgery.Engorged bronchial arterys with medial hypertrophy and overgrowth of the small branches were noted near the bronchus in the resected specimen.The patient recovered uneventfully and was discharged on postoperative day 14. | Toshihiro Kitajima Kota Momose Seigi Lee Shusuke Haruta Masaki Ueno Hisashi Shinohara Sakashi Fujimori Takeshi Fujii Ryoji Takei Tadasu Kohno Harushi Udagawa | 2015 | World Journal of Gastroenterology2015，21，11： | 3 |
| 5 | Ulcerative colitis patients in clinical remission demonstrate correlations between fecal immunochemical test results, mucosal healing, and risk of relapse显示文摘AIM: To assess the risk of relapse in ulcerative colitis(UC) patients in clinical remission using mucosal status and fecal immunochemical test(FIT) results. METHODS: The clinical outcomes of 194 UC patients in clinical remission who underwent colonoscopy were based on evaluations of Mayo endoscopic subscores(MESs) and FIT results.RESULTS: Patients with an MES of 0(n = 94, 48%) showed a ten-fold lower risk of relapse than those with an MES of 1-3(n = 100, 52%)(HR = 0.10, 95%CI: 0.05-0.19). A negative FIT result(fecal hemoglobin concentrations ≤ 100 ng/m L) was predictive of patients with an MES of 0, with a sensitivity of 0.94 and a specific of 0.76. Moreover, patients with a negative FIT score had a six-fold lower risk of clinical relapse than those with a positive score(HR = 0.17, 95%CI: 0.10-0.28). Inclusion of the distinguishing parameter, sustaining clinical remission > 12 mo, resulted in an even stronger correlation between negative FIT results and an MES of 0 with respect to the risk of clinical relapse(HR = 0.11, 95%CI: 0.04-0.23).CONCLUSION: Negative FIT results one year or more after remission induction correlate with complete mucosal healing(MES 0) and better prognosis. Performing FIT one year after remission induction may be useful for evaluating relapse risk. | Asuka Nakarai Jun Kato Sakiko Hiraoka Shiho Takashima Daisuke Takei Toshihiro Inokuchi Yuusaku Sugihara Masahiro Takahara Keita Harada Hiroyuki Okada | 2016 | World Journal of Gastroenterology2016，22，21： | 3 |

| 7 | Image-based autonomous navigation of Hayabusa2 using artificial landmarks: The design and brief in-flight results of the first landing on asteroid Ryugu显示文摘Hayabusa2 is an asteroid sample return mission carried out by the Japan Aerospace Exploration Agency.The spacecraft was launched in 2014 and arrived at the target asteroid Ryugu on June 27,2018.During the 1.5-year proximity phase,several critical operations(including two landing/sampling operations)were successfully performed.They were based on autonomous image-based descent and landing techniques.This paper describes an imagebased autonomous navigation scheme of the Hayabusa2 mission using artificial landmarks named target markers(TMs).Its basic algorithm,and the in-flight results of the first touchdown and its rehearsal,are shown. | Naoko Ogawa Fuyuto Terui Yuya Mimasu Kent Yoshikawa Go Ono Seiji Yasuda Kota Matsushima Tetsuya Masuda Hiroki Hihara Junpei Sano Takashi Matsuhisa Satoshi Danno Manabu Yamada Yasuhiro Yokota Yuto Takei Takanao Saiki Yuichi Tsuda | 2020 | Astrodynamics2020，4，2： | 2 |
| 8 | Effect of branched-chain amino acids in patients receiving intervention for hepatocellular carcinoma显示文摘AIM:To investigate the usefulness of branched-chain amino acids(BCAA)before transarterial chemoembolization(TACE)or radiofrequency ablation(RFA).METHODS:We investigated the usefulness of preintervention with BCAAs by comparing patients treated with BCAAs at 12.45 g/d orally for at least 2 wk before TACE or RFA and those not receiving such pretreatment.A total of 270 patients with hepatocellular carcinoma complicated by cirrhosis were included in the study.Mean changes from baseline(Δ)in serum albumin(Alb),C-reactive protein(CRP),and transaminase levels,as well as peak body temperature were also determined and compared at days 2,5,and 10 after the start of TACE or RFA.RESULTS:In patients who underwent TACE or RFA,BCAA pre-intervention significantly suppressed the development of post-intervention hypoalbuminemia and reduced inflammatory reactions during the subsequent clinical course.After TACE,theΔAlb peaked on day 2,remained constantly lower in BCAA-treated patients,compared to the control group,and was-0.13±0.42g/dL in BCAA-treated patients and-0.33±0.51 g/dL in untreated patients on day 10.TheΔCRP was also significantly lower in BCAA-treated patients on days2,5 and 10 after TACE.Like the trends noted after TACE,a similar tendency was noted as to theΔAlb andΔCRP after RFA.The changes in serum Alb level were inversely correlated with CRP changes;therefore,a possible involvement of the anti-inflammatory effect of BCAAs was inferred as a factor contributory to the suppression of decrease in serum Alb level.CONCLUSION:Pre-intervention with BCAAs may hasten the recovery of serum Alb level and mitigate postoperative complications in patients undergoing TACE or RFA. | Tomoaki Ishihara Motoh Iwasa Hideaki Tanaka Masahiko Kaito Jiro Ikoma Toshiya Shibata Yoshiyuki Takei | 2014 | World Journal of Gastroenterology2014，20，10： | 2 |
| 9 | Ureteral calculi secondary to a gradually migrated acupuncture needle显示文摘We herein presented a case of calculi secondary to a migrated acupuncture needle.A 74-year-old woman with a history of acupuncture therapy for lumbago was referred to our hospital for treatment of ureteral and renal pelvic calculi.Abdominal multi-detector computed tomography scans showed ipsilateral hydronephrosis and two calculi secondary to a migrated acupuncture needle.First,a percutaneous nephrolithotomy was performed to extract two calculi and fine needle fragments from the pelvis.Subsequently,residual needle fragments and calculi in the ureter were then removed by flexible transurethral lithotripsy using a holmium laser.In the present case,the formation of the calculi was caused by a migrated acupuncture needle.Calculi and needle fragments were removed safely endoscopically because the whole calculi and needle fragments were located in the ureteral lumen.ª2021 Editorial Office of Asian Journal of Urology.Production and hosting by Elsevier B.V.This is an open access article under the CC BY-NC-ND license(http://gffzzeb6f7f563f66445dhkbuupoffuucv6kv0.ffgz.tsg.suse.edu.cn/licenses/by-nc-nd/4.0/). | Masahiro Matsuki Atsushi Wanifuchi Ryuta Inoue Fumiyasu Takei Yasuharu Kunishima | 2021 | Asian Journal of Urology2021，8，1： | 2 |

| 12 | The deep-space multi-object orbit determination system and its application to Hayabusa2’s asteroid proximity operations显示文摘The deep-space multi-object orbit determination system(DMOODS)and its application in the asteroid proximity operation of the Hayabusa2 mission are described.DMOODS was developed by the Japan Aerospace Exploration Agency(JAXA)for the primary purpose of determining the trajectory of deep-space spacecraft for JAXA’s planetary missions.The weighted least-squares batch filter is used for the orbit estimator of DMOODS.The orbit estimator supports more than 10 data types,some of which are used for relative trajectory measurements between multiple space objects including natural satellites and small bodies.This system consists of a set of computer programs running on Linux-based consumer PCs on the ground,which are used for orbit determination and the generation of radiometric tracking data,such as delta differential one-way ranging and doppler tracking data.During the asteroid proximity phase of Hayabusa2,this system played an essential role in operations that had very strict navigation requirements or operations in which few optical data were obtained owing to special constraints on the spacecraft attitude or distance from the asteroid.One example is orbit determination during the solar conjunction phase,in which the navigation accuracy is degraded by the effect of the solar corona.The large range bias caused by the solar corona was accurately estimated with DMOODS by combining light detection and ranging(LIDAR)and ranging measurements in the superior solar conjunction phase of Hayabusa2.For the orbiting operations of target markers and the MINERVA-II2 rover,the simultaneous estimation of six trajectories of four artificial objects and a natural object was made by DMOODS.This type of simultaneous orbit determination of multi-artificial objects in deep-space has never been accomplished before. | Hiroshi Takeuchi Kent Yoshikawa Yuto Takei Yusuke Oki Shota Kikuchi Hitoshi Ikeda Stefania Soldini Naoko Ogawa Yuya Mimasu Go Ono Fuyuto Terui Naoya Sakatani Manabu Yamada Toru Kouyama Shingo Kameda Takanao Saiki Yuichi Tsuda | 2020 | Astrodynamics2020，4，4： | 2 |

| 14 | Gastric submucosa-invasive carcinoma associated with EpsteinBarr virus and endoscopic submucosal dissection: A case report显示文摘BACKGROUND Epstein-Barr virus(EBV)-associated carcinoma is a gastric cancer subtype with a morphology characterized by gastric carcinoma with lymphoid stroma(GCLS).Clinicopathological studies have indicated a better prognosis for GCLS than for common gastric carcinomas.Some previous cases of early gastric cancer associated with EBV had been diagnosed by endoscopic resection.CASE SUMMARY We present two GCLS cases subjected to endoscopic submucosal dissection(ESD)for a definitive diagnosis.A protruded gastric lesion was identified by routine endoscopic examination,but forceps biopsy showed no atypical cells before ESD.The resected specimen showed a poorly differentiated adenocarcinoma with lymphoid cells involving the mucosa and submucosa.The final diagnosis was submucosa-invasive poorly differentiated gastric adenocarcinoma.Accordingly,additional gastrectomy was recommended to obtain a complete cure.One patient underwent additional distal gastrectomy with lymph node dissection,but the other was refused because of cardiovascular complications.Both patients remained in remission for more than half a year.EBV positivity was determined by EBV-encoded RNA in situ hybridization.We also conducted a literature review of cases of early gastric cancer associated with EBV that had been diagnosed by ESD.CONCLUSION Submucosa-invasive GCLS could be dissected using ESD,and EBV positivity should be subsequently assessed to determine whether or not any additional curative surgery is required.Further prospective investigations on the prevalence of lymph node metastasis in EBV-associated carcinoma should be performed to expand the indications for endoscopic resection. | Yu Kobayashi Takehito Kunogi Hiroki Tanabe Yuki Murakami Takuya Iwama Takahiro Sasaki Keitaro Takahashi Katsuyoshi Ando Yoshiki Nomura Nobuhiro Ueno Shin Kashima Kentaro Moriichi Hidehiro Takei Mikihiro Fujiya Toshikatsu Okumura | 2019 | World Journal of Gastrointestinal Oncology2019，11，10： | 2 |
