Over recent decades, many studies have reported that hypocrellin A(HA) can eliminate cancer cells with proper irradiation in several cancer cell lines. However, the precise molecular mechanism underlying its anticancer effect has not been fully defined. HA-mediated cytotoxicity and apoptosis in human lung adenocarcinoma A549 cells were evaluated after photodynamic therapy(PDT). A temporal quantitative proteomics approach by isobaric tag for relative and absolute quantitation(iTRAQ) 2 D liquid chromatography with tandem mass spectrometric(LC–MS/MS) was introduced to help clarify molecular cytotoxic mechanisms and identify candidate targets of HA-induced apoptotic cell death. Specific caspaseinhibitors were used to further elucidate the molecular pathway underlying apoptosis in PDT-treated A549 cells. Finally, down-stream apoptosis-related protein was evaluated. Apoptosis induced by HA was associated with cell shrinkage, externalization of cell membrane phosphatidylserine, DNA fragmentation,and mitochondrial disruption, which were preceded by increased intracellular reactive oxygen species(ROS) generations. Further studies showed that PDT treatment with 0.08 mmol/L HA resulted in mitochondrial disruption, pronounced release of cytochrome c, and activation of caspase-3,-9, ***, HA may be a possible therapeutic agent directed toward mitochondria and a promising photodynamic anticancer candidate for further evaluation.

Chemical Research in Chinese Universities 2015年第3期31卷 401-405页

作者： YANG Shuang GUO Zhihua YANG Xuewei XIE jing robert j.lee jIANG Dan TENG Lesheng College of Life Sciences Jilin University Changchun 130012 P.R.China College of Pharmacy The Ohio State University Columbus 43210 USA

We described a novel approach for survivin fatty acid-modified polyethylenimine. A linoleic acid siRNA cellular delivery via a cationic liposome incorporating derivative of branched polyethylenimine（PEI, Mw=25 kDa）, PEI-LA, was synthesized and incorporated into the liposome. The properties of the liposome, cytotoxicity, cellular uptake of cancer cells for survivin siRNA, survivin protein downregulation levels were investigated. PEl-modified liposome showed a lower cytotoxicity and delivered survivin siRNA into HeLa cells and A549 cells efficiently com- pared with PEI-25kDa.

Current surgical treatments for Parkinson's disease and potential therapeutic targets

Neural Regeneration Research 2018年第8期13卷 1342-1345页

作者： Darrin j.lee robert F.Dallapiazza Philippe De Vloo Andres M.Lozano Division of Neurosurgery Toronto Western Hospital Department of Surgery University of Toronto

Currently, the most common surgical treatment for Parkinson＇s disease is deep brain stimulation（DBS）. This treatment strategy is typically reserved for bradykinesia, rigidity and tremor in patients who no longer respond to medication in a predictable manner or who suffer medication-induced dyskinesias. In addition to DBS, ablative procedures like radiofrequency, radiosurgery and focused ultrasound are also utilized for select tremor symptoms. In this review, we discuss evolving surgical techniques, targets, and emerging technology. In addition, we evaluate potential paradigm shifts in treatment, including gene therapy, immunotherapy and cell transplantation. While these new techniques and treatment options are still in their infancy, advances in Parkinson＇s disease treatment are rapidly expanding.

Introduction:Alzheimer 's disease(AD) is a common neurodegenerative disorder and the primary cause of dementia. Considerable evidence supports the “amyloid hypothesis,” stating that the pathogenesis of AD is primarily caused by the deposition of amyloid-β(Aβ), which drives tau phosphorylation, neuroinflammation, and neurodegeneration in the brain. The amyloid hypothesis is strengthened by the significant and moderate benefit of lecanemab, a humanized antibody through an anti-amyloid mechanism,showing slowed clinical decline(van Dyck et al.,2023). The recent positive results of anti-amyloid trials have brought back focus on the amyloid hypothesis through biochemical, genetic, and pharmacological approaches(Zhang, 2023).

Gastrointestinal manifestations of systemic mastocytosis

引用

World journal of Gastroenterology 2008年第45期14卷 7005-7008页

作者： jason K lee Scott j Whittaker robert A Enns Peter Zetler Internal Medicine University of British Columbia St. Paul's Hospital Division of Gastroenterology University of British Columbia St. Paul's Hospital Division of Pathology University of British Columbia

Systemic mastocytosis (SM) is a rare disease with abnormal proliferation and infiltration of mast cells in the skin, bone marrow, and viscera including the mucosal surfaces of the digestive tract. Gastrointestinal (GI) symptoms occur in 14%-85% of patients with systemic mastocytosis. The GI symptoms may be as frequent as the better known pruritis, urticaria pigmentosa, and flushing. In fact most recent studies show that the GI symptoms are especially important clinically due to the severity and chronicity of the effects that they produce. GI symptoms may include abdominal pain, diarrhea, nausea, vomiting, and bloating. A case of predominantly GI systemic mastocytosis with unique endoscopic images and pathologic confirmation is herein presented, as well as a current review of the GI manifestations of this disease including endoscopic appearances. Issues such as treatment and prognosis will not be discussed for the purposes of this paper.

The primary aim of antihypertensive therapy is to reduce or normalize blood pressure of the patients, so that we can lower the incidence of morbidity and mortality which are related to cardiovascular complications due to hypertension. It is also desirable that antihypertensive treatments can prevent or reverse cardiovascular changes, so that after a certain treat ment period, it may be possible to withdraw the treat ments without the risk of hypertension. However, most studies to date have shown that withdrawal of treat ments usually resulted in rebound hypertension, with the re-establishment of hypertension within a very

A New Species of Amsassia from the Ordovician of Korea and South China:Paleobiological and Paleogeographical Significance

引用

Acta Geologica Sinica(English Edition) 2016年第3期90卷 796-806页

作者： Mirinae lee Heeju PARK Nguyen Viet TIEN Suk-joo CHOH robert j.ELIAS Dong-jin lee Department of Earth and Environmental Sciences Andong National UniversityAndong36729Republic of Korea Institute of Geological Sciences-Vietnam Academy of Science and Technology(IGS-VAST) Hanoi100000Socialist Republic of Vietnam Department of Earth and Environmental Sciences Korea UniversitySeoul02841Republic of Korea Department of Geological Sciences The University of ManitobaWinnipegR3T 2N2Canada

A new species of the probable calcareous alga Amsassia, A. koreanensis, is recognized from the Duwibong Formation （Middle Ordovician, Darriwilian） of the Taebaeksan Basin in mid-eastern Korea. This is the first report of the genus from the Korean Peninsula, expanding its geographical range to the eastern Sino-Korean Block. The new species also occurs in the Xiazhen Formation （Upper Ordovician, Katian） at Zhuzhai in the South China Block. Amsassia koreanensis is the smallest species of this modular genus, having a maximum module diameter of 0.28 ram. Module increase is by bipartite, tripartite and quadripartite types of longitudinal axial fission, but unlike other species of the genus, quadripartite fission is common. The types of fission are comparable to those in some Tetradiida （now Prismostylales, florideophycean rhodophyte algae）, although the processes of fission are different. The distribution of A. koreanensis further strengthens the biogeographical connection between the Sino-Korean and South China blocks, suggesting that these two paleocontinents were located closer together during the Middle to Late Ordovician than previously speculated.

作者： robert j. Antony joseph Tse-Hei lee Canton's Thirteen Hongs Research Center Guangzhou University Guangzhou 510006 China Department of History and Confucius Institute Pace University New York NY 10038 USA

It has been over forty years since jean Chesneaux published his edited volume Popular Movements and Secret Societies in China, and some twenty years since David Ownby and Mary Somers Heidhues published their edited volume Secret Societies Reconsidered On popular religions, both Daniel Overmyer＇s FoItc Buddhist Religion and Susan Naquin＇s Millenarian Rebellion in China were also published almost forty years ago.1 Although there have been a number of important studies published both inside and outside of China on secret societies and popular religions since the 1990s, in recent years there has been a surge in new research, much of it still unpublished, on this important subject in Chinese history.
