Various Modifications of Müller’s Muscle-Conjunctival Resection for Ptosis Repair
Shu-Lang Liao,Ann Yi-chiun Chuang 대한미용성형외과학회 2015 Archives of Aesthetic Plastic Surgery Vol.21 No.2
Background The posterior approach for ptosis, including the Fasanella-Servat procedure and Müller’s muscle-conjunctival resection (MMCR), has been proven effective for mild- to moderately affected patients whose levator muscle function remains relatively intact. Traditionally, MMCR was reserved for phenylephrine test-positive patients for whom various modifications and several nomograms have been developed. Methods We reviewed the literature for the Fasanella-Servat procedure and MMCR. The methods and results of the different modifications were analyzed and compared. Nomograms of these two procedures were summarized. Results MMCR mainly involved resection of Müller’s muscle and conjunctiva in the original design by Putterman and co-workers. The suggested resection ranged from 8 to 9 mm for the achievement of the maximal effect produced by topical epinephrine. Perry included tarsectomy in his procedure and developed a new nomogram that included a 1:1 ratio of the ptosis correction to the amount of tarsus resection. The effect of tarsectomy for the Fasanella-Servat procedure in terms of eyelid elevation was approximately one-half the value seen in phenylephrine test-negative patients. We’ve performed MMCR with tarsectomy regardless of the response to phenylephrine with similar results to Perry. Surgical indications and possible complications of MMCR with tarsectomy for Asian patients are discussed. Conclusions MMCR is an effective and simple method for the correction of ptosis. With baseline MMCR, the additional tarsectomy has proven to be a powerful tool for ptosis correction irrespective of phenylephrine test results.

The physical mechanisms of electron mobility and balistic drain curent enhancement by stress are investigated. From modified higher-order k·p band calculations, the stress-induced split of the conduction band edge and the effective mass change are quantitatively evaluated. It was experimentaly and theoreticaly demonstrated that the energy surface of 2-fold valeys in Si NMOSFETs on a (001) wafers is especially warped due to a uniaxial [110] stress, resulting in a lighter transverse effective mass of the 2-fold valleys parallel to the stress. The physical reasons for the warped subband structure and the abnormal mobility enhancement caused by the uniaxial stres are investigated. The rates of variation of the experimental electron mobility in NMOSFETs on wafers with (01) orientations undera <110> uniaxial stress as a function of the channel direction is theoretically studied. The limits of electron mobility enhancement and the effectiveness of stress enginering in enhancing the balistic drain current of NMOSFETs are also discussed.

Studying the Strain Effect on Silicon Atomic Wires
Shu-Tong Chang,Shu-Hui Liao,Hsiao-Chun Huang,Chee-Wee Liu,Chung-Yi Lin 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.53 No.6
The transport properties of a Si3 atomic wire system, which is formed by a Si3 cluster connected to two lithium electrodes with bias applied, is studied using the simulator Virtual NanoLab that is constructed based on the non-equilibrium Green’s function (NEGF) scheme. We investigated the Si3 atomic wire system under three strain conditions (tensile, compressive and shear). Different trends in the I-V characteristics are observed for the three cases at various applied biases. The transmission spectrum T(E, Vb), as a function of energy and applied biases, are analyzed. The interactions among eigenstates of the molecular projected self-consistent Hamiltonian (MPSH) strongly affect the transport properties of the system.

Antitumor Activity of Chloroquine in Combination with Cisplatin in Human Gastric Cancer Xenografts
Zhang, Hui-Qing,Fang, Nian,Liu, Xiao-Mei,Xiong, Shu-Ping,Liao, Yu-Qian,Jin, Wen-Jian,Song, Rong-Feng,Wan, Yi-Ye Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.9
Purpose: To investigate the antitumor activity and mechanism of chloroquine (CQ) in combination with cisplatin (DDP) in nude mice xenografted with gastric cancer SGC7901 cells. Materials and Methods: 35 cases of gastric cancer patients with malignant ascites were enrolled and intraperitoneal cisplatin injection was performed. Ascites were collected before and 5 days after perfusion for assessment of autophagy levels in cancer cells. In addition, 24 tumor-bearing mice were randomly divided into control, DDP, CQ and CQ + DDP groups. Results: In 54.3% (19/35) of patients the treatment was therapeutically effective (OR), 5 days after peritoneal chemotherapy, 13 patients had the decreased ascites Beclin-1 mRNA levels. In 16 patients who had NR, only 2 cases had decreased Beclin-1 (P=0.001). Compared with the control group, the xenograft growth in nude mice in the DDP group was low, and the inhibition rate was 47.6%. In combination with chloroquine, the inhibition rate increased to 84.7% (P<0.01). The LC3-II/I ratio, and Beclin1 and MDR1/P-gp expression were decreased, while caspase 3 protein levels increased (P<0.05). Conclusions: Antitumor ability of cisplatin was associated with autophagy activity and chloroquine can enhance chemosensitivity to cisplatin in gastric cancer xenografts nude mice.

Background: Myocardial ischemia reperfusion injury (MIRI) is an important mechanism of post-myocardial infarction injury and a main cause of death in patients with ischemic heart disease. Electroacupuncture (EA) pretreatment is effective for the prevention and treatment of MIRI, but mechanisms mediating the effects of cardiovascular disease EA treatments remain unclear. Objectives: To determine whether the lateral hypothalamus (LHA) and the cerebellar fastigial nucleus (FN) are involved in the protective effects of EA stimulation on MIRI. Methods: EA pretreatment was performed for 7 days before the establishment of the MIRI model. ST-segment changes on electrocardiograms were recorded and the Curtis–Walker arrhythmia score was used to evaluate changes in reperfusion injury. Hematoxylin–eosin staining was applied to evaluate the pathological and morphological changes in myocardial tissue. c-fos expression in the LHA and FN was determined by immunofluorescence staining. Glutamic (Glu) and γ-Aminobutyric acid (GABA) levels were measured using a high-performance liquid chromatography-electrochemical method. Results: EA pretreatment reduced ST-segment elevation, arrhythmia scores, and morphological changes in MIRI myocardial cells in rats, and decreased the c-fos protein expression in LHA/FN nuclei. MIRI was associated with an imbalance between GABA and Glu levels, whereas EA pretreatment increased GABA levels and decreased Glu levels in the LHA/FN. Conclusion: FN and LHA are involved in the EA-mediated attenuation of MIRI. Pretreatment with EA plays a protective role in the myocardium by regulating Glu and GABA release in the LHA and FN.
