Branched-chain amino acid treatment before transcatheter arterial chemoembolization for hepatocellular carcinoma

引用

World Journal of Gastroenterology 2012年第12期18卷 1379-1384页

作者： Hiroki Nishikawa Yukio Osaki Tadashi Inuzuka Haruhiko Takeda Jun Nakajima Fumihiro Matsuda Shinichiro Henmi Azusa Sakamoto Tetsuro Ishikawa Sumio Saito Ryuichi kita Toru Kimura Department of Gastroenterology and Hepatology Osaka Red Cross Hospital

AIM： To examine the significance of branched-chain amino acid （BCAA） treatment before transcatheter arterial chemoembolization （rACE） for hepatocellular carcinoma （HCC）.METHODS： This study included 99 patients who underwent TACE therapy for HCC at our hospital and were followed up without treatment for at least 6 mo between January 2004 and January 2010. They were divided into 2 groups： those receiving BCAA granules （/7 = 40） or regular diet （n = 59, control）. Data obtained were retrospectively analyzed （prior to TACE, and 1 wk, 1, 3, and 6 mo after TACE） in terms of nutritional condition and clinical laboratory parameters （serum albumin level and Child-Pugh score）, both of which are determinants of hepatic functional reserve.RESULTS： The BCAA group comprised 27 males and 13 females with a mean age of 69,9 ：E 8,8 years, The patients of the BCAA group were classified as follows： Child-Pugh A/B/C in 22/15/3 patients, and Stage Ⅱ/Ⅲ/ /IVA HCC in 12/23/5 patients, respectively. The controlgroup comprised 32 males and 27 females with a mean age of 73.2 ± 10.1 years. In the control group, 9 patients had chronic hepatitis, Child-Pugh A/B/C in 39/10/1 patients, and Stage Ⅰ/Ⅱ/Ⅲ/IVA HCC in 1/11/35/12 patients, respectively. Overall, both serum albumin level and Child-Pugh score improved significantly in the BCAA group as compared with the control 3 and 6 mo after TACE （P 〈 0.05）. Further analysis was performed by the following categorization：（1） child-Pugh classification; （2） liver cirrhosis subgroup with a serum albumin level 〉 3.5 g/dL; and （3） epirubicin dose. A similar trend indicating a significant improvement of all variables in the BCAA group was noted （P 〈 0.05）.CONCLUSION： Treatment with BCAA granules in patients who have undergone TACE for HCC is considered useful to maintain their hepatic functional reserve.

Vascular remodeling and mobilization of bone marrow-derived cells in cuff-induced vascular injury in LDL receptor knockout mice

Background Vascular remodeling is an important pathologic process in vascular injury for various vascular disorders such as atherosclerosis, postangioplasty restenosis and transplant arteriopathy. Recently, pathologic change and the role of bone marrow derived cells were wildly studied in atherosclerosis and restenosis. But the manner of lesion formation in neointima and cell recruitment in vascular remodeling lesion in the present of hypercholesterolemia is not yet fully understood. Methods Double-transgenic mice knockout of LDL receptor gene （LDL-/-） and expressing ubiquitously green fluorescent protein （GFP） were obtained by cross-breeding LDL -/- mice with the GFP-expressing transgenic mice. LDL-/- mice （22-24 weeks of age） fed high fat diet containing 1.25% （w/w） cholesterol were subjected to 9Gy irradiation and received bone marrow （BM） cells from the double-transgenic mice. Four weeks later, a nonconstrictive cuff was placed around the right femoral artery. After another 2 weeks, both right and left femoral arteries were harvested and subjected to histochemical analysis. Apoptosis was analyzed in situ using TUNEL assay. Results Two weeks after cuff placement, atherosclerotic lesions developed in the intima consisting of a massive accumulation of foam cells. The tissue stained with anti-α smooth muscle actin （SMA） antibody, showed a number of SMA-positive cells in the intimal lesion area. They were also positive for GFP, indicating that BM-derived cells can differentiate to SMCs in the intima in cuff-induced vascular remodeling lesions. Numerous small vessels in the adventitia as well as the endothelial lining of the intima were positive both for CD31 and GFP. The intima and media showed a large number of TUNEL-positive signals after 2 weeks cuff injury, indicating the presence of apoptosis in vascular remodeling. Conclusions Atherosclerotic lesions in mice can be developed in the intima after 2 weeks of cuff-induced vascular injury under the hypercholes

Paraneoplastic syndromes associated with lung cancer

Paraneoplastic syndromes are signs or symptoms that occur as a result of organ or tissue damage at locations remote from the site of the primary tumor or metastases. Paraneoplastic syndromes associated with lung cancer can impair various organ functions and include neurologic, endocrine, dermatologic, rheumatologic, hematologic, and ophthalmological syndromes, as well as glomerulopathy and coagulopathy(Trousseau's syndrome). The histological type of lung cancer is generally dependent on the associated syndrome, the two most common of which are humoral hypercalcemia of malignancy in squamous cell carcinoma and the syndrome of inappropriate antidiuretic hormone secretion in small cell lung cancer. The symptoms often precede the diagnosis of the associated lung cancer, especially when the symptoms are neurologic or dermatologic. The proposed mechanisms of paraneoplastic processes include the aberrant release of humoral mediators, such as hormones and hormone-like peptides, cyto-kines, and antibodies. Treating the underlying cancer is generally the most effective therapy for paraneoplastic syndromes, and treatment soon after symptom onset appears to offer the best potential for symptom improvement. In this article, we review the diagnosis, potential mechanisms, and treatments of a wide variety of paraneoplastic syndromes associated with lung cancer.

S1-1 Studies on toxicity of Chinese medicines and decreased virulence through the compatibility of herbal ingredientsLI Peng-Tao (CST)(Beijing University of Traditional Chinese Medicine, Beijing 100029, China)Abstract:Beginning from the report of the renal injury induced by aristolochic acid, the poisonous side effects of Chinese medicines have attracted more and more attentions, which have produced huge influence on the progress of traditional Chinese medicines. It becomes a vitally important issue to understand and use Chinese medicines correctly. The toxicity of Chinese herbal medicines which takes place in recent years, can generalize to 4 aspects: ① improper usage of Chinese medicine properties causes the steady state of body out of balance and leads to the adverse responses of patients beyond the range of indications; ② because of the generalization of “dual modulation effect” of Chinese medicines, as well as the misunderstanding of non-poisonous nature of Chinese herbs, it makes the term of taking medicine unnecessarily long and then causes the hypercorrection or accumulative poisoning; ③ paying much attention to the chemical compositions of patent Chinese medicines while ignoring the impact of processing methods on the property of effective substances in crude drug and the significance of the compatibility of herbal ingredients.

随着机械装置向高速重载发展,工况条件更显恶劣,因此机械零件要使用高硬度耐磨损的新型材料,而且零件尺寸要精密、表面粗糙度要低;这往往难以用传统的磨削加工工艺来达到。解决的方法,一是使用硬度高、耐磨度高的磨料制造的砂轮,如金刚钻或立方氮(?)硼砂轮,这是目前广泛使用的工艺方法。另一途径,是近年来一直在研究的联合能量磨削,既能加工出高精度尺寸的表面,还可提高磨削效率。
