Peroxisome proliferative-activated receptor (PPAR) γ coactivator-1α (PGC-1α) is a transcriptional coactivator of PPARγ.PGC-1α can bind with many different transcription factors.It plays a number of functions in the different tissues and the process of biological reaction.Recent studies have shown that PGC-1α signaling pathway has a neuroprotective effect.This article reviews the neuroprotective effect of PGC-1α in cerebral ischernia and its possible mechanisms.

PURPOSE: To cmpare the clinical results of complex tibial plateau fractures treated by hybrid external fixation and dual plate fixation. MATERIALS AND METHODS: We studied forty patients with Schatzker type V and VI fractures respectively and selected twenty seven patients who were followed at least one year between January 2000 and December 2005. We evaluated the clinical results in which fourteen fractures with hybrid external fixation were compared with thirteen fractures with dual plate fixation. The clinical results were evaluated according to Knee Society Clinical Rating System and the statistical analysis was performed by Student t-test. RESULTS: There were no significant differences in terms of bone union time (average union time: dual plate fixation 13.8 weeks, hybrid external fixation 14.2 weeks). The quality of osseous reduction was superior in the fractures with dual plate fixation than those with hybrid external fixation. There were significant differences in functional score (average functional score: dual plate fixation 73, hybrid external fixation 62), but not in average knee score. CONCLUSION: The hybrid external fixation can be a useful modality for treatment of complex proximal tibial plateau fractures. But the good quality of the fracture reduction by dual plate fixation may be a indicator for favorable prognosis for satisfactory knee function.

Bartter's syndrome is a rare tubular disorder characterized by hypokalemic, hypochloremic metabolic alkalosis, hyperreninemic, hyperaldosteronism, hyporesponsiveness to pressor agents and juxtaglomerular apparatus heperplasia. We report a case of Bartter's syndrome of a 5 month-old male infant with subdural hematoma who was confirmed by characteristic clinical, laboratory findings and kidney biopsy.

BACKGROUND: Dizziness is a common complaint in patients presenting to the emergency room and that has various pathologic causes. This study investigate the clinical differences in dizziness between the central origin and the peripheral origin and to provides the clues far diagnosis and proper treatment. METHODS: We analysed 290 patients with dizziness during 12 months period prospectively, who visited in ED, Inha University Hospital from Jan. 1997 to Dec. 1997. We analysized sex ratio, characteristics of the dizziness, associated past illness, associated symptoms, severity, results of the special radiologic study, nystagmus type, and causes of central origin and peripheral origin dizziness. RESULTS: Male to female ratio was 1:1.4 in central origin(n=165) and 1:2.0 in peripheral origin(n=125). Most common age group was 11th decade in both groups. According to the characteristics of the dizziness, rotation sense was the main complaint of the peripheral origin dizziness. Most common past illness was hypertension in both groups. MRI has diagnostic priority than CT scan in central origin dizziness. Types of nystagmus has some significant differences between two groups. CONCLUSION: Dizziness may represented as a sign of significant pathological neurologic status especially in central origin. So we must precisely evaluate the patient history, neurologic examination of the inner ear and CNS, and special radiologic study incliding MRI.

Significant difference in diffused carbon monoxide percentage and change of heart rates before and after stair climbing test was found in LPF group (P0.05).Conclusions Patients of lung cancer intolerable for lobectomy by static pulmonary function test can be screened by stair climbing test before surgical operation,which can make some of them regain opportunity of surgical operation.

Mechanically the symphysis pubis serves to anchor the ends of the two weight bearing arches of the pubis-the femorosacral and ischiosacral arches. Under normal conditions it has been found to exceedingly resistant to separation. Sacroiliac strain is also uncommon because the sacroiliac ligaments are very strong and the movement which produce a torsion strain upon the joint is more likely to cause a strain of thinner capsular ligaments surrounding the small lumbosacral joints. We experienced a case of separation of the symphysis pubis and 2 cases of sacroiliac strain during and after spontaneous labor.

Bottoming out is the term used to describe the inferior displacement of a breast implant after breast augmentation that results in increased distance between the nipple areolar complex and the inframammary fold. Conventional techniques for correcting bottoming out involve capsulectomy and capsulorrhaphy via an inframammary fold incision that is prone to cause large scar and increases the patient's burden. However, using an endoscopic approach via the axilla, we are able to correct bottoming out, resulting in a smaller scar and shorter recovery time. In this article, we present a novel and simple method to correct bottoming out using endoscopy and electrocauterization.

Background:
The relationship between cystitis glandularis (CG) and bladder malignancy remains unclear.
Methods:
We identified the oncologic significance of CG at the molecular level using liquid chromatography-tandem mass spectrometry-based proteomic analysis of 10 CG, 12 urothelial carcinoma (UC), and nine normal urothelium (NU) specimens. Differentially expressed proteins (DEPs) were identified based on an analysis of variance false discovery rate < 0.05, and their functional enrichment was analyzed using a network model, Gene Set Enrichment Analysis, and Gene Ontology annotation.
Results:
We identified 9,890 proteins across all samples and 1,139 DEPs among the three entities. A substantial number of DEPs overlapped in CG/NU, distinct from UC. Interestingly, we found that a subset of DEP clusters (n = 53, 5%) was differentially expressed in NU but similarly between CG and UC. This “UC-like signature” was enriched for reactive oxygen species (ROS) and energy metabolism, growth and DNA repair, transport, motility, epithelial-mesenchymal transition, and cell survival. Using the top 10 shortlisted DEPs, including SOD2, PRKCD, CYCS, and HCLS1, we identified functional elements related to ROS metabolism, development, and transport using network analysis. The abundance of these four molecules in UC/CG than in NU was consistent with the oncologic functions in CG.
Conclusions
Using a proteomic approach, we identified a predominantly non-neoplastic landscape of CG, which was closer to NU than to UC. We also confirmed a small subset of common DEPs in UC and CG, suggesting that altered ROS metabolism might imply potential cancerous risks in CG.
