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.

AIM： To produce an antibody against rat eosinophil cationic protein （ECP） and to examine the effects of the antibody in rats with dextran sulfate sodium （DSS）-induced colitis. METHODS： An antibody was raised against rat ECP. Rats were treated with 3% DSS in drinking water for 7 d and received the antibody or normal serum. The colons were examined histologically and correlated with clinical symptoms. Immunohistochemistry and Western blot analysis were estimated as a grade of inflammation. RESULTS： The ECP antibody stained the activated eosinophils around the injured crypts in the colonic mucosa. Antibody treatment reduced the severity of colonic ulceration and acute clinical symptoms （diarrhea and/or bloodstained stool）. Body weight gain was significantly greater and the colon length was significantly longer in anti-ECPtreated rats than in normal serum-treated rats. Expression of ECP in activated eosinophils was associated with the presence of erosions and inflammation. The number of Ki-67-positive cells in the regenerated surface epithelium increased in anti-ECP-treated rats compared with normal serum-treated rats. Western blot analysis revealed reduced expression of macrophage migration inhibitory factor （MIF） in anti-ECP-treated rats. CONCLUSION： Our results indicate that treatment with ECP antibody, improved DSS-induced colitis in rats, possibly by increasing the regenerative activity of the colonic epithelium and downregulation of the immune response, and suggest that anti-ECP may promote intestinal wound healing in patients with ulcerative colitis （UC）.

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.

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. Comprehensive sequential treatment using chemical peeling, vitamin C iontophoresis and topical vita

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.

An 18-year-old man had numerous multiple painful nodulocystic lesions, pustules, and necrotic hemorrhagic ulcerative lesions with crusts on the face, back, chest and upper arm two weeks ago. Systemic symptoms such as fever, general fatigue and arthralgia were not observed. Laboratory findings revealed an elevated white blood cell count with a neutrophilia and C-reactive protein. Oral antimicrobials did not respond. Consequently, oral prednisolone (20 mg/d) for two weeks induced remarkable improvement promptly. A case of acne fulminans without systemic symptoms successfully treated with oral corticosteroids has been reported.

Although interferon (IFN) based therapy for recurrent hepatitis C virus (HCV) infection after liver transplantation has been widely accepted, it induces various adverse effects such as thrombocytopenia, resulting in its interruption. Recently, concomitant splenectomy at the time of living donor liver transplantation (LDLT) has been tried to overcome this problem, but this procedure leads to several complications such as excessive intraoperative bleeding and serious infection. A 60-year-old female received LDLT using a left lobe graft from her second son for liver failure caused by hepatitis C-related cirrhosis. Six months after LDLT, she was diagnosed as recurrent HCV infection by liver biopsy. IFN monotherapy was started from 7 mo after LDLT and her platelet count decreased to less than 50 000/μL, which thus made it necessary to discontinue the treatment. We decided to attempt laparoscopic splenectomy (LS) under general anesthesia. Since intra-abdominal findings did not show any adhesion formations around the spleen, LS could be successfully performed. After LS, since her platelet count immediately increased to 225 000/μL 14 d after operation, IFN therapy was restarted and we could convert the combination therapy of IFN and ribavirin, resulting in no detectable viral marker. Inconclusion, LS can be performed safely even after LDLT, and LS after LDLT is a feasible and less invasive modality for thrombocytopenia caused by antiviral therapy.
