| 1 | Preliminary experience with drug-coated balloon angioplasty in primary percutaneous coronary intervention显示文摘We evaluated the clinical feasibility of using drugcoated balloon(DCB) angioplasty in patients undergoingprimary percutaneous coronary intervention(PPCI). Between January 2010 to September 2014,89 STelevation myocardial infarction patients(83% male,mean age 59 ± 14 years) with a total of 89 coronary lesions were treated with DCB during PPCI. Clinical outcomes are reported at 30 d follow-up. Left anterior descending artery was the most common target vessel for PCI(37%). Twenty-eight percent of the patients had underlying diabetes mellitus. Mean left ventricular ejection fraction was 44% ± 11%. DCB-only PCI was the predominant approach(96%) with the remaining 4% of patients receiving bail-out stenting. Thrombolysis in Myocardial Infarction(TIMI) 3 flow was successfully restored in 98% of patients. An average of 1.2 ± 0.5 DCB were used per patient,with mean DCB diameter of 2.6 ± 0.5 mm and average length of 23.2 ± 10.2 mm. At 30-d follow-up,there were 4 deaths(4.5%). No patients experienced abrupt closure of the infarctrelated artery and there was no reported target-lesion failure. Our preliminary experience showed that DCB angioplasty in PPCI was feasible and associated with a high rate of TIMI 3 flow and low 30-d ischaemic event. | Hee Hwa Ho Julian Tan Yau Wei Ooi Kwok Kong Loh Than Htike Aung Nwe Tun Yin Dasdo Antonius Sinaga Fahim Haider Jafary Paul Jau Lueng Ong | 2015 | World Journal of Cardiology2015，7，6： | 14 |
| 2 | 尖锐心肌的梗塞: 在在新加坡的年轻成年人的临床的特征和结果显示文摘 AIM: To investigate the clinical features and in-hospital outcomes of young adults with acute myocardial infarction (AMI) in Singapore. METHODS: Between January 2005 to September 2010, 333 consecutive patients aged ≤ 45 years old were diagnosed to have AMI at our institution. As Singapore is a multi-ethnic society, we also analysed whether ethnic differences exist between the three dominant ethnic groups, Malay, Chinese and Indian with regards to the clinical features. Clinical data was collected retrospectively on demographic characteristics, presenting signs and symptoms, blood investigation, angiographic findings and in-hospital clinical outcomes. RESULTS: The mean age at presentation was 40.2 ± 4.0 years with male predominance (94%). The majority of patients were Chinese (51%) followed by Indians (31%) and Malays (18%). The most common risk factor was smoking (74%) followed by hypertension (28.5%) and hyperlipidemia (20.0%). 37% of patients were obese. The majority of patients had single vessel disease (46%) on coronary angiography. The mean total cholesterol, low-density lipoprotein and highdensity lipoprotein levels were 5.6±1.2 mmol/L, 3.8±1.1 mmol/L and 0.93±0.25 mmol/L respectively. The mean left ventricular function was 44%±10% with the incidence of heart failure 3% and cardiogenic shock 4.5%. Overall in-hospital mortality was low with 4 deaths (1.2%). For ethnic subgroup analysis, Indians have a 3-fold risk of developing premature AMI when compared to other ethnic groups. CONCLUSION: Young AMI patients in Singapore are characterized by male predominance, high incidence of smoking and obesity. Overall in-hospital clinical outcomes are favourable. Among the 3 ethnic groups, Indians have the highest risk of developing premature AMI. | Chun Pong Wong Seet Yoong Loh Kwok Kong Loh Paul Jau Lueng Ong David Foo Hee Hwa Ho | 2012 | World Journal of Cardiology2012，4，6： | 13 |
| 3 | Pan-CDK inhibition augments cisplatin lethality in nasopharyngeal carcinoma cell lines and xenograft models显示文摘In addition to their canonical roles in regulating cell cycle transition and transcription,cyclin-dependent kinases(CDKs)have been shown to coordinate DNA damage response pathways,suggesting a rational pairing of CDK inhibitors with genotoxic chemotherapeutic agents in the treatment of human malignancies.Here,we report that roniciclib(BAY1000394),a potent pan-CDK inhibitor,displays promising anti-neoplastic activity as a single agent and potentiates cisplatin lethality in preclinical nasopharyngeal carcinoma(NPC)models.Proliferation of the NPC cell lines HONE-1,CNE-2,C666-1,and HK-1 was effectively curbed by roniciclib treatment,with IC_(50)values between 11 and 38 nmol/L.These anticancer effects were mediated by pleiotropic mechanisms consistent with successful blockade of cell cycle CDKs 1,2,3,and 4 and transcriptional CDKs 7 and 9,ultimately resulting in arrest at G1/S and G2/M,downregulation of the transcriptional apparatus,and repression of anti-apoptotic proteins.Considerably enhanced tumor cell apoptosis was achieved following combined treatment with 10 nmol/L roniciclib and 2.0μmol/L cisplatin;this combination therapy achieved a response over 250%greater than either drug alone.Although roniciclib chemosensitized NPC cells to cisplatin,it did not sensitize untransformed(NP69)cells.The administration of 0.5 mg/kg roniciclib to BALB/c xenograft mice was well tolerated and effectively restrained tumor growth comparable to treatment with 6 mg/kg cisplatin,whereas combining these two agents produced far greater tumor suppression than either of the monotherapies.In summary,these data demonstrate that roniciclib has strong anti-NPC activity and synergizes with cisplatin chemotherapy at clinically relevant doses,thus justifying further evaluation of this combinatorial approach in clinical settings. | Nicholas LSyn Pei Li Lim Li Ren Kong Lingzhi Wang Andrea Li-Ann Wong Chwee Ming Lim Thomas Kwok Seng Loh Gerhard Siemeister Boon Cher Goh Wen-Son Hsieh | 2018 | Signal Transduction and Targeted Therapy2018，3，1： | 0 |
