AIM： To review the surgical outcomes in terms of the surgical indications and relevant prognostic factors. METHODS： Sixteen patients underwent therapeutic lung surgery between March 1999 and May 2006. The observation period was terminated on May 31, 2007. The surgical outcomes and the clinicopathological factors were compared. RESULTS： There was no mortality or major morbidity encountered in this study. The mean follow-up period after metastasectomy was 26.7 ＋ 28.2 （range： 1-99 mo）, and the median survival time was 20 mo. The 1- and 5-year survival rates were 56% and 26%, respectively. At the end of the follow-up, 1 patient died from hepatic failure without recurrence, 6 died from hepatic failure with a recurrent hepatocellular carcinoma （HCC）, and 4 died from recurrent HCC with cachexia. Among several clinical factors, Kaplan Meier analysis revealed as a treatment for the that liver transplantation primary lesion, grade of cell differentiation, and negative evidence HBV infection were independent predictive factors. On Cox＇s proportional hazard model, there were no significant factors affecting survival after pulmonary metastasectomy in patients with HCC. CONCLUSION： A metastasectomy should be performed before other treatments in selected patients, Although not significant, patients with liver transplantation of a primary HCC survived longer, Liver transplantation might be the most beneficial modality that can offer patients better survival, A multi- institutional and collaborative study would be needed for identifying clinical prognostic factors predicting survival in patients with HCC and lung metastasis.

Microsomal epoxide hydrolase (EPHX1) is involved in the activation and detoxification of exogenous chemicals. Genetic polymorphisms in EPHX1 have been associated with the development of leukemia. To investigate an association between single-nucleotide polymorphisms (SNPs) of EPHX1 and risk factors for childhood acute lymphoblastic leukemia (ALL) in Korean children, we genotyped two SNPs, Tyr113His (rs1051740) and His139Arg (rs2234922) in 185 childhood ALL cases and 536 healthy controls. Genotyping for these two SNPs was performed by simplex pyrosequencing assay and high-resolution melt analysis, respectively. We found that the Tyr113His genotype was associated with a decreased risk of childhood ALL (odds ratio, OR = 0.64, 95% confidence interval, CI = 0.43 - 0.93;p = 0.02). There was no association between His139Arg and the combined genotypes and the risk of childhood ALL. These results suggest that the EPHX1 113TyrHis genotype may protect against leukemogenesis in childhood.

We report a facile coagglomeration method for preparing graphene (G)/MgCl2‐supported Ti‐based Ziegler‐Natta catalysts. The effects of graphene feed ratio on catalyst morphology and ethylene polymerization behavior were examined. The synthesized catalyst exhibited very high activity for ethylene polymerization. The resultant polyethylene (PE)/G nanocomposites showed a layered morphology, and the graphene fillers were well dispersed in the PE matrix. In addition, the thermal stability and mechanical properties of PE were significantly enhanced with the introduction of a very small amount of G fillers (0.05 wt%). This work provides a facile approach to the production o fhigh‐performance PE.

Mechanical lithotripsy （ML） is usually considered as a standard treatment option for large bile duct stones. However, it is impossible to retrieve oversized stones because the conventional lithotripsy basket may not be able to grasp the stone. However, there is no es- tablished endoscopic extraction method for such gi- ant stone removal. We describe a case of successful extraction of a 4-cm large stone using a gastric bezoar basket. A 78-year-old woman had suffered from upper abdominal pain for 20 d. Contrast-enhanced computed tomogram revealed a 4-cm single stone in the distal common bile duct （CBD）. Endoscopic stone retraction was decided upon and endoscopic papillary balloon dilation was performed using a large balloon. An at- tempt to capture the stone using a standard lithotripsy basket failed due to the large stone size. Subsequently, we used a gastric bezoar basket to successfully capturethe stone. The stone was fragmented into small pieces and extracted. The stone was completely removed after two sessions of endoscopic retrograde cholangio- pancreatography; each of which took 30 rain. No com- plications occurred during or after the procedure. The patient was fully recovered and discharged on day 11 of hospitalization. ML using a gastric bezoar basket is a safe and effective retrieval method in select cases, and is considered as an alternative nonoperative option for the management of difficult CBD stones.

本文运用多种地质统计学方法分析了岩石节理的空间变化性,并建立了节理方位、密度和长度参数的完整模型、通过对这些典型参数空间变化性的量测以及对交差图的分析,按无偏最小估计方差(即克立格方差)估计的克立格方法建立模型.运用普通克立格法建立局部块段节理的确定性模型以服务于某露天矿的论证,而且采用这种确定性模型能够进行边坡稳定性、块度和水力渗流系统等各种岩土工程分析.用克立格估计值和实际量测值之间的对比来检验岩体节理模型,其结果是肯定的.同时还发现节理参数的局部统计特征与其整体统计特征明显不同.由于岩体节理在任何岩土工程分析中都起重要作用,故任何岩土工程分析都必须进行局部模型分析.
