Lymphangioma usually occurs in children and usually involves the skin. Mesenteric lymphangioma is extremely rare in adults. Typically, lymphangioma appears on computed tomography (CT) as a lower attenuation of a cystic mass, however, some cases appear to be a solid mass. We describe the CT and 18F-FDG positron emission tomography/CT appearance in a case of jejunal and mesenteric cavernous lymphangi-omatosis mimicking metastasis in an adult patient with rectal cancer.

近年来．随着超声医学研究的发展．高强聚焦超声在临床医学方面的应用日益得到重视。研究者们发现．超声空化效应是高强聚焦超声的生物效应的重要作用机理之一（主要是超声空化效应）。超声作用在生物体上时所产生的空化效应可以在很短时问内产生巨大能量，达到基因／药物输运，杀死肿瘤细胞．阻塞病变血管，止血等目的洲。然而在产生理想的治疗作用的同时，超声的空化作用也可能造成正常细胞或组织的损伤，而产生此类损伤的重要因素之一是由空化泡瞬间破裂放出巨大能量引起温度迅速上升所导致的热损伤。因此，如果在有效利用高强聚焦超声的治疗作用的同时，避免产生热损伤已经成为超声临床医学的重要课题。本文的工作旨在研究在低占空比条件下高强聚焦超声的空化效应在兔子耳部血管中所产生的升温作用。

Among the regression-based algorithms for deriving SST from satellite measurements, regionally optimized algorithms normally perform better than the corresponding global algorithm. In this paper, three algorithms are considered for SST retrieval over the East Asia region （15°-55°N, 105°-170°E）, including the multi-channel algorithm （MCSST）, the quadratic algorithm （QSST）, and the Pathfinder algorithm （PFSST）. All algorithms are derived and validated using collocated buoy and Geostationary Meteorological Satellite （GMS-5） observations from 1997 to 2001. An important part of the derivation and validation of the algorithms is the quality control procedure for the buoy SST data and an improved cloud screening method for the satellite brightness temperature measurements. The regionally optimized MCSST algorithm shows an overall improvement over the global algorithm, removing the bias of about -0.13℃ and reducing the root-mean-square difference （rmsd） from 1.36℃ to 1.26℃. The QSST is only slightly better than the MCSST. For both algorithms, a seasonal dependence of the remaining error statistics is still evident. The Pathfinder approach for deriving a season-specific set of coefficients, one for August to October and one for the rest of the year, provides the smallest rmsd overall that is also stable over time.

BACKGROUND：Prothymosinα（PTMA）is a nuclear oncoprotein-transcription factor essential for cell cycle progression and *** was overexpressed in several human malignancies including hepatocellular carcinoma（HCC）.However,the prognostic significance of PTMA protein expression in HCC remains *** the present study,we evaluated PTMA protein expression by immunohistochemistry in order to elucidate the prognostic roles of PTMA in HCC ***： By immunohistochemistry, we investigated the expression of PTMA protein in tumor tissue from 226 HCC patients who underwent curative hepatectomy. Univariate and multivariate analyses were performed to evaluate its predic- tive value for tumor recurrence and survival of patients. The median follow-up period was 120 months. RESULTS： PTMA expression was observed in 162 （71.7%） of the 226 HCC patients and was significantly associated with higher Edmondson grade, microvascular invasion, intrahe- patic metastasis, higher American Joint Committee on Cancer （AJCC） T-stage, and lower albumin level. PTMA expression was an independent predictor of early recurrence （P=0.001）. PTMA expression showed an unfavorable influence on recurrence- free survival （RFS）（P〈0.001）. Subgroup analysis showed that among patients with tumor size _〈5.0 cm （140 patients）, patients at AJCC T-stage I （95 patients） and patients with a-fetoprotein ≤20 ng/mL （83 patients）, the differences in RFS between PTMA- positive and PTMA-negative groups were also statistically sig- nificant （P=0.017, P=0.002 and P=0.002, respectively）. In addi- tion, PTMA expression was an independent predictor of shorter RFS （P=0.011）. PTMA expression showed an unfavorable influ- ence on overall survival （P=0.014）, but was not an independent predictor of shorter overall survival （P=0.161）. CONCLUSIONS： PTMA protein expression might be a novel predictor of early recurrence and RFS in HCC patients, even those at early stage or with a-fetoprotein-negative after curative hep
