BACKGROUND:A malignant fibrous histiocytoma,recently referred to as an undifferentiated pleomorphic sarcoma (UPS),is very rare in the liver,and only 34 cases of primary hepatic malignant fibrous histiocytoma have been reported in the English literature. METHODS:We report a rare case of a hepatic UPS presenting as a unilocular cystic lesion with respect to histopathologic features,the newly revised diagnostic criteria,and the differential diagnosis. RESULTS:A 60-year-old man presented for evaluation of epigastric pain of 7 months *** computed tomography revealed a hypodense,unilocular cystic mass in the right lobe of the liver,measuring 14.0×11.1 cm.A right lobectomy was ***,the cut surface showed a single,well-circumscribed unilocular cystic tumor mass containing dark red-brown necrotic debris and blood clots, which occupied most of the ***,the tumor consisted of haphazardly arranged mononuclear pleomorphic tumor cells,admixed with abundant osteoclast- like multinucleated giant ***,the tumor cells expressed vimentin *** histopathologic and immunohistochemical findings were compatible with a *** patient is alive and well 41 months after surgery without recurrence. CONCLUSIONS:Clinically,most of the hepatic UPSs are solid *** two cases have presented as multilocular cystic masses.A primary hepatic UPS presenting as a unilocular cyst has never been reported.A UPS should be included in the differential diagnosis of unilocular cystic lesions in the liver.

Teaching the Non-Chinese Speaking Students Origami to Improve Their Interest and Concentration in Learning Chinese Language

引用

Journal of Literature and Art Studies 2017年第10期7卷 1331-1336页

作者： lee Kit Fong The University ofHong Kong Hong Kong China

The difficulties in learning Chinese faced by non-Chinese students are the subjects of concern in the education sector, especially in writing Chinese characters. We write the characters with strokes and dots, more or less strokes or dots will represent different words and different meanings. Students found these very complicated and confused, thus it leads them to lose their motivation and interest in learning Chinese language. From the beginning of the 1990s, I began using origami as one of the activities to promote the teaching of Chinese in the state school in Melbourne Australia with remarkable results. Program got widely reported by Medias. In 1995, I got the ＂National Excellence in Teaching Awards＂. After I took up the position as the curriculum development officer in University of Hong Kong in 2007, I worked closely with the teachers and students using origami as the theme base learning in Chinese. It helps to increase their understanding of the radicals and parts, so as to improve their confidence in writing Chinese characters.

Evaluation of Clinical Outcomes after LASIK for the Correction of Myopia Using the Advanced Customvue Excimer Laser Platform

引用

Open Journal of Ophthalmology 2018年第3期8卷 150-160页

作者： Hung Ming lee lee Hung Ming Eye Centre Gleneagles Hospital Singapore

-Purpose: To evaluate early visual, refractive and aberrometric outcomes after wave front-guided LASIK for the correction of low to moderate myopia and myopic astigmat is musing the excimer laser platform Advanced Custom Vue. Methods: A prospective, non-comparative study in 100 myopic eyes of 50 patients evaluating LASIK results over a period of 3 months. Main outcome variables included visual acuity, refraction, total higher-order aberrations (HOAs), spherical aberration (SA) and coma-like aberration. The surgery was performed using the VISX STAR S4 (Johnson and Johnson Vision) excimer laser and a wave front-guided ablation designed according to the iDesign aberrometer data (Johnson and Johnson Vision). Results: Mean preoperative sphere decreased from -4.07 ± 1.78 D to 0.32 ± 0.30 D at 3 months after surgery. Mean preoperative cylinder was reduced from -1.09 ± 0.88 D to -0.26 ± 0.28 D after the complete follow-up. Postoperative uncorrected distance visual acuity (UDVA) was 0.00 logMAR (20/20) or better in 100% of eyes, and 65.3% of eyes reached an UDVA of -0.20 logMAR (20/12.5) or better (p < 0.05). For a 6-mm pupil, the root mean square (RMS) for total ocular HOAs increased with surgery by 0.03 μm (p = 0.050), whereas the coma-like RMS increased by 0.05 μm (p < 0.001). The change in spherical aberration was +0.08 μm (p < 0.001). Conclusion: Wavefront-guided LASIK using the new generation excimer laser platform Advanced Custom Vue is safe and effective for treating myopia and myopic astigmatism, minimizing the postoperative level of HOAs.

Detection of human papillomavirus L1 gene DNA fragments in postmortem blood and spleen after Gardasil^(■) vaccination—A case report

引用

Advances in Bioscience and Biotechnology 2012年第8期3卷 1214-1224页

作者： Sin Hang lee Milford Hospital and Milford Molecular Laboratory MilfordConnecticutUSA

A same-nested PCR was used to re-amplify the amplicon of a hypervariable region of the HPV-16 L1 gene DNA in the postmortem blood and splenic tissue obtained at autopsy of a formerly healthy teenage girl who suffered a sudden unexpected death in sleep 6 months after 3 intramuscular injections of a quadrivalent HPV vaccine, Gardasil?. A full autopsy analysis revealed no cause of death. The HPV-16 gene DNA detected in the postmortem materials was similar to the HPV-16 gene DNA fragments in Gardasil? in that both were in non-B-conformation, requiring nondegenerate GP6 and MY11 primers to re-amplify the PCR amplicon for detection and to generate a template useful for direct DNA sequencing. A sequence excised from the base-calling DNA sequencing electropherogram was analyzed by Basic Local Alignment Search Tool (BLAST) alignment and a 45 - 60 base sequence fully matched with a standard hypervariable region of the HPV-16 L1 gene retrieved from the National Center for Biotechnology Information database validated the correct genotyping for HPV- 16 L1 gene DNA. These naked non-proliferating HPV- 16 L1 gene DNA fragments appeared to be in the macrophages of the postmortem blood and spleen, and were protected from degradation by binding firmly to the particulate aluminum adjuvant used in vaccine formulation. The significance of these HPV DNA fragments of a vaccine origin found in post-mortem materials is not clear and warrants further investigation.

Remaining Vigilant Can even a one-sided collapse crash China’s economy?

引用

Beijing Review 2014年第28期57卷 36-37页

作者： Ann lee New York University

The topic of shadow banking has now become the topic du jour of what will crash the Chinese economy. Before that, it was the real estate bubble, and before that, the rising cost of cheap labor. Of course, many wrong predictions later, the bears of China continue to prognosticate that China will crash because they have a vested inter- est in seeing China crash. I am not going to say that China will never hit a speed bump. In fact, I think that scenario is likely, but not for the reasons that the China bears often use. But first, the shadow banking issue.

Analyzing the H19-and T65-epitopes in 38 kd phosphory-lated protein of Marek's disease viruses and comparing chicken immunological reactions to viruses point-mutated in the epitopes

引用

Science China(Life Sciences) 2004年第1期47卷 82-91页

作者： lee Lucy F Avian Disease and Oncology Laboratory East Lansing Ml 48823 USA

DNA sequencing analysis in 38 kd phosphorylated protein (pp38) ORF of Marek's disease viruses (MDV) indicated that all tested 10 virulent strains with different pathotypes had 'A' at base #320 and glutamine at aa#107 while reacted with monoclonal antibody (Mab) H19 in indirect fluorescence antibody test (IFA). However, vaccine strain CVI988 had 'G' at base#320 and arginine at aa#107 instead, when it was negative in IFA with Mab H19. Some strains were also reactive with Mab T65 in IFA while there was 'G' at base #326 and glycine at aa#109, but the other strains, which had 'A' at base #326 and glutamic acid at aa#109, did not react with Mab T65. By comparison of CVI988 to its point mutants CVI/rpp38(AG) and CVI/rpp38(AA) with 1 or 2 base(s) changes at bases #320 and /or #326 of pp38 gene for their reactivity with Mab H19 and T65, it was confirmed that the glutamine at aa#107 and glycine at aa#109 were critical to epitopes H19 and T65 respectively. Immuno-reactions to MDV were compared in SPF chickens inoculated with cloned CVI988 and its mutant CVI/rpp38(AG). It was found that antibody responses to MDV in chickens inoculated with CVI/rpp38(AG) were delayed and significantly lower than that in chickens inoculated with the native CVI988. By differential comparison of antibody titers to different antigens, a third epitope specific to CVI988 and dependent on arginine at aa#107 was suggested to be responsible for the big difference in antibody responses induced by native CVI988 and its mutant.
