BACKGROUND Minimally invasive surgery for gastric cancer(GC) has gained widespread use as a safe curative procedure especially for early *** To determine risk factors for postoperative complications after minimally invasive gastrectomy for *** Between January 2009 and June 2019, 1716 consecutive patients were referred to our division for primary GC. Among them, 1401 patients who were diagnosed with both clinical and pathological Stage Ⅲ or lower GC and underwent robotic gastrectomy(RG) or laparoscopic gastrectomy(LG) were enrolled. Retrospective chart review and multivariate analysis were performed for identifying risk factors for postoperative *** Morbidity following minimally invasive gastrectomy was observed in 7.5% of the patients. Multivariate analyses demonstrated that non-robotic minimally invasive surgery, male gender, and an operative time of ≥ 360 min were significant independent risk factors for morbidity. Therefore, morbidity was compared between RG and LG. Accordingly, propensity-matched cohort analysis revealed that the RG group had significantly fewer intra-abdominal infectious complications than the LG group(2.5% vs 5.9%, respectively;P = 0.038), while no significant differences were noted for other local or systemic *** analyses of the propensity-matched cohort revealed that non-robotic minimally invasive surgery [odds ratio = 2.463(1.070–5.682);P = 0.034] was a significant independent risk factor for intra-abdominal infectious *** The findings showed that robotic surgery might improve short-term outcomes following minimally invasive radical gastrectomy by reducing intra-abdominal infectious complications.

Cerebral lipiodol embolism related to a vascular lake during chemoembolization in hepatocellular carcinoma:A case report and review of the literature

World Journal of Gastroenterology 2018年第37期24卷 4291-4296页

A male patient underwent conventional transcatheter chemoembolization for advanced recurrent hepatocellular carcinoma(HCC). Even after the injection of 7 m L of lipiodol followed by gelatin sponge particles, the flow of feeding arteries did not slow down. A repeat angiography revealed a newly developed vascular lake draining into systemic veins; however, embolization was continued without taking noticing of the vascular lake. The patient's level of consciousness deteriorated immediately after the procedure, and non-contrast computed tomography revealed pulmonary and cerebral lipiodol embolisms. The patient's level of consciousness gradually improved after 8 wk in intensive care. In this case, a vascular lake emerged during chemoembolization and drained into systemic veins, offering a pathway carrying lipiodol to pulmonary vessels, the most likely cause of this serious complication. We should be aware that vascular lakes in HCC may drain into systemic veins and can cause intratumoral arteriovenous shunts.

Comprehensive Sequential Successful Therapy Comprising Chemical Peeling, Iontophoresis and Topical Vitamin C for Postinflammatory Hyperpigmentation in Acne Vulgaris

引用

Journal of Cosmetics, Dermatological Sciences and Applications 2020年第3期10卷 99-103页

作者： ichiro Kurokawa Department of Dermatology Meiwa Hospital Nishinomiya Japan

A 20-year-old man presented with for 6-month history of facial acne. He had erythema and red papules on the face secondary to BPO-induced contact dermatitis. He was administered topical corticosteroid. Contact dermatitis improved with this treatment, and he had red papules, comedones, prominent postinflammatory hyperpigmentation (PIH), postinflammatory erythema (PIE), erosions and erythema associated with acne vulgaris. He was subsequently treated with oral minocycline 100 mg/d and topical adapalene and ozenoxacin lotion once daily for 3 months. The inflammatory lesions and comedo subsided;however, PIH, PIE, atrophic scar and erosion persisted. During 3 months, the patient underwent chemical peeling using 20% glycolic acid (GA) and subsequent vitamin C iontophoresis twice at 1-month intervals. He showed almost disappearance of red papules and comedones but persistent PIH, PIE and erosion after 3 months of treatment. He was thereafter prescribed topical glyceryl-octyl-ascorbic acid/ascorbyl 2-phosphate 6-palmitate/DL-a-tocopherol phosphate complex for local application twice daily for 3 months. After 7 months of treatment, PIH, PIE, erosion and atrophic scar faded significantly with only trace residual erosions, atrophic scar and PIH. Subsequently, he was prescribed local application of 2% isostearyl-L-ascorbic acid gel vitamin C gel twice daily for 3 months. After 15 months, PIH, PIE, erosion and atrophic scar disappeared completely with significant improvement. Comprehensive sequential therapy resulted in significant improvement. It is suggested that medical treatment using systemic and topical antimicrobials and topical adapalene reduces inflammatory lesions and comedones initially. Subsequent chemical peeling using GA and vitamin C iontophoresis could improve PIH. These synergistic effects might have contributed to the significant improvement observed in this case.

On China’s Exchange Rate Flexibility and Stability: The More Flexible against the U.S. Dollar, the More Stable in Effective Terms

引用

China & World Economy 2005年第6期13卷 3-9页

作者： ichiro Otani Economic Policy Consultant Potomac Maryland U.S.A

The Chinese authorities have often emphasized the importance of maintaining the renminbi＇s stable exchange rate without stating explicitly how this stability should be measured. This paper argues that the relevant concept for this stability should be in terms of the rnminbi＇s effective exchange rate, rather than its rate against any particular currency, such as the U. S. dollar. Under the current circumstances where key currencies＇ exchange rates fluctuate freely, if the authorities wish to maintain the stability of the renmnibi＇s effective exchange rate, they would want to let the renminbi＇s exchange rate fluctuate much more against the U. S. dollar than in the past because such fluctuations would greatly reduce the magnitude of the renminbi＇s fluctuations against other key currencies and thus its effective exchange rate. This point has been demonstrated by illustrative figures and by comparing the renminbi＇s hypothetical, greater exchange rate fluctuations with its actual fluctuations.

Bacterial Cells as Model Factories

引用

American Journal of Operations Research 2013年第1期3卷 81-86页

作者： ichiro Matsumura Department of Biochemistry Center for Fundamental and Applied Molecular Evolution Emory University Atlanta USA

Bacteria, like industrial engineers, must manage processes that convert low value inputs into high value outputs. Bacteria are not intelligent, so they utilize self-organizing production systems to accelerate life-sustaining chemical processes. Here I explore two questions. First, can businesses apply the principles of self-organization? Second, can operations researchers contribute to our understanding of biological systems? I explain biochemical concepts in plain terms, illustrated with a few informative laboratory evolution experiments, and describe the organizing principles that underlie complex biological systems. I describe the new disciplines of synthetic biology and metabolic engineering, which offer opportunities for interdisciplinary collaboration between life scientists and operations researchers.
