The Study of Alignment among the Current Secondary School Textbooks of Arts and Humanities Learning Area, Instruction and Competency Indicators
Cheng-Ta Hsieh
Journal of Textbook Research , 2010,
Abstract: The main purpose of this study is to judge the correlation among current arts and humanities textbooks, instruction, and competency indicators for Grades 1-9 Curriculum Guideline. The data is collected through questionnaires answered by 13 secondary school art teachers. The conclusion can be summarized as follows:Sex, seniority and major of the teachers have a correlation with curriculum alignment. Degree level does not correlate. Time used, reason for use, degree of dependence and importance of instruction don’t correlate with curriculum alignment. Only textbook version correlates. The author suggests that future studies can align content between standards and assessment, and thoroughly compare various versions of art and humanities textbooks, as well as further investigate observation of instruction in classrooms to provide references for revising indicators and editing textbooks.

Szu-Kai Hsu, Cheng-Ta Hsieh, Chih-Ta Huang, Jing-Shan Huang
Surgical Science (SS) , 2012, DOI: 10.4236/ss.2012.311104
Abstract: Background: Park-bench position is a commonly used position in patients operated with cerebellopontine tumor, microvascular decompression, or lesions of cerebellar hemisphere and vertebral artery. Several complications associated with this positioning have been described. However, the delayed airway complication resulting from park-bench position has been rarely reported in the literatures. Herein, we report a rare case of delayed airway obstruction after a posterior-fossa craniotomy with park-bench position for acoustic neuroma. Case presentation: A 43-year-old woman, who has a right acoustic neuroma, was placed in the park-bench position for a posterior-fossa craniotomy. The anesthesia and operation were performed smoothly. However, progressive swelling in the left neck with extending to left face occurred two hours after endo-tracheal extubation. Computed tomographic scan of neck revealed diffuse swelling of the muscles and deep soft tissue in the left side. No obvious embolization of vascular system including jugular vein was found in the sonography. Because of obstruction in upper airway, orotracheal intubation and a head-up position were performed. The clinical symptoms improved gradually since the third post-operative day. She was discharged with obvious complications on the 23rd day after the operation. Conclusion: The possible mechanisms may originate from the kinking of the jugular vein due to hyper-flexed neck position during surgery. To prevent such complication, we must take great care of the anesthetized patients when placed in the forced neck position and always keep this rare but so critical complication in mind.
Role of the Peripheral Sympathetic Innervations in Controlling Cerebral Blood Flow after the Transection of Bilateral Superior Cervical Sympathetic Ganglia Two Weeks Later  [PDF]
Cheng-Ta Hsieh, Shinn-Zong Lin, Ming-Ying Liu
Surgical Science (SS) , 2011, DOI: 10.4236/ss.2011.24041
Abstract: Background: Cerebral blood vessels are mainly supplied by sympathetic nerves arising from the superior cervical ganglia and cerebral blood volume may be influenced by bilateral superior cervical ganglionectomy (SCG). Various stages of cerebral blood volume changes depended on the time following bilateral excision of SCG. In this study, we emphasize the subacute effect (two weeks) on the local cerebral blood flow (LCBF). Material and Methods: Sprague-Dawley rats weighing 250 ~ 400 gm (n = 20) were selected into two groups. Under the ambient temperature 20oC, the first group animals (n = 10) received sham operation and the other group animals (n = 10) underwent bilateral SCG. The LCBF and O2 delivery of 14 brain struc-tures were measured for each animal by the use of 14C-iodoantipyrine technique two weeks after the opera-tion. Results: The average of LCBF was decreased from 150 ml/100 gm/min to 129 ml/100 gm/min after bi-lateral SCG. Only the LCBF at basal ganglia was increased from 108 ml/min/100 g in the sham-operated group to 118 ml/min/100g in the SCG group. A mean of 14% reduction of LCBF was estimated. In 14 brain structures, the delivery amount of O2 was all decreased, except in basal ganglia. However, these changes of LCBF and the delivery amount of O2 at these 14 brain structures did not reach the significant differences. Conclusions: The present results show that chronic effect (two weeks) of bilateral SCG on LCBF was not only in a decrease of the LCBF, but also a decrease of local cerebral O2 delivery. However, the changes didn’t show the significant differences.
Peripheral T-Cell Lymphoma of Cervical Spine  [PDF]

Surgical Science (SS) , 2012, DOI: 10.4236/ss.2012.32019
Abstract: Peripheral T-cell lymphoma is a rather uncommon non-Hodgkin’s lymphoma with the initial manifestation of spinal cord compression. Herein, we reported a 74-year-old woman with sustained neck pain radiating into the right shoulder and arm and weakness of the right upper extremity. A mass that had invaded the C5 and C6 vertebral bodies, causing a kyphotic curvature and compressing the spinal cord, was discovered with magnetic resonance imaging. The patient then underwent anterior corpectomy at C5 and C6, and reconstruction with a titanic rod and bone cement. The pathology confirmed a diagnosis of peripheral T-cell lymphoma after serial H & E and immunohistochemical staining. She recovered well from her profound neurological deficit. Both chemotherapy and radiotherapy were used postoperatively. Surgical intervention is indicated in these cases to decompress the cord, remove the majority of the tumor mass, stabilize the spine and obtain tissue for pathological diagnosis.

Pain Relief in Patients Treated With Percutaneous Vertebroplasty: An Evaluation Cement Volume
Cheng-Ta HSIEH,Jui-Ming SUN,Shih-Youeng CHUANG,Ming-Ying LIU
Journal of Neurological Sciences , 2008,
Abstract: Background: To evaluate the correlation between the injected volume of cement and pain-relief in patients with single level of osteoporotic compression fractures treated by percutaneous vertebroplasty (PVP).Material and Methods: A total of twenty-three patients comprising 13 women and 10 men who received a one level vertebroplasty were consecutively enrolled in this study. The injected volume of PMMA ranged from 2 mL to 8 mL. Depend on the volume of injected cement, these patients divided into two groups. The relevant injected volume of cement and the pre-operative and post-operative visual analogue scores of pain were analyzed.Conclusions: There was no significant correlation between the injected volume of cement and pain-relief. Only 4 mL could reduce the pain and achieve good clinical results. Percutaneous verterbroplasty is an effective treatment for patients with a painful single level osteoporotic compression fracture.

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0070089
Abstract: Prefrontal left-right functional imbalance and disrupted prefronto-thalamic circuitry are plausible mechanisms for treatment-resistant depression (TRD). Add-on repetitive transcranial magnetic stimulation (rTMS), effective in treating antidepressant-refractory TRD, was administered to verify the core mechanisms underlying the refractoriness to antidepressants. Thirty TRD patients received a 2-week course of 10-Hz rTMS to the left dorsolateral prefrontal cortex (DLPFC). Depression scores were evaluated at baseline (W0), and the ends of weeks 1, 2, and 14 (W14). Responders were defined as those who showed an objective improvement in depression scores ≥50% after rTMS. Left-right frontal alpha asymmetry (FAA) was measured by magnetoencephalography at each time point as a proxy for left-right functional imbalance. Prefronto-thalamic connections at W0 and W14 were assessed by studying couplings between prefrontal alpha waves and thalamic glucose metabolism (PWTMC, reflecting intact thalamo-prefrontal connectivity). A group of healthy control subjects received magnetoencephalography at W0 (N = 50) to study whether FAA could have a diagnostic value for TRD, or received both magnetoencephalography and positron-emission-tomography at W0 (N = 10) to confirm the existence of PWTMC in the depression-free state. We found that FAA changes cannot differentiate between TRD and healthy subjects or between responders and non-responders. No PWTMC were found in the TRD group at W0, whereas restitution of the PWTMC was demonstrated only in the sustained responders at W14 and euthymic healthy controls. In conclusion, we affirmed impaired prefronto-thalamic functional connections, but not frontal functional imbalance, as a core deficit in TRD.

Abstract: Studies have indicated that flavonoid luteolin is a potential inhibitor of tumor cell proliferation and may function as an anticarcinogenic agent. Pyrrolidine dithiocarbamate (PDTC), a synthetic compound, may exhibit biphasic effects on apoptosis depending on the experimental context. Previously, we found that luteolin induced the activation of the proapoptotic proteins, such as Bad, Bid, and Bax, in HL-60 human leukemia cells. We also explored the modulatory effects and molecular mechanisms of PDTC on the cytotoxicity of luteolin in HL-60 cells; PDTC could interfere with luteolin’s ability to cleave poly(ADP-ribose)-polymerase (PARP) and DNA fragmentation of factor-45 (DFF-45). In the current study, we further investigated the effect of PDTC on the luteolin-induced death-receptor pathway and the cleavage of the Bcl-2 family members. We found that the combination of luteolin and PDTC increased the survival of the HL-60 cells such that PDTC inhibited both extrinsic and intrinsic pathways in luteolin-induced apoptosis.
