Abstract?AlM:To study the thickness changes of retinal nerve fiber layer ( RNFL) in Parkinson's disease ( PD) .?METHODS:Fifteen eyes of 15 PD patients in early stage and 18 eyes of 18 controls were chosen to take RNFL examination by optical coherence tomography ( OCT ) . Circular scans were taken around the optic nerve head (diameter = 3. 46mm) to record the features of RNFL. Scanning areas included eight quadrants of the temporal, superior, nasal, inferior, inferior-temporal, superior-temporal, inferior-nasal and superior-nasal quadrant. RNFL thickness was comparatively analyzed in eight quadrants and the average level in two groups.?RESULTS: RNFL thickness in two groups in temporal, superior, nasal , inferior, temporal- inferior, temporal-superior, nasal-inferior, nasal-superior were: ( control/PD) 83. 2 ± 17. 5μm/68. 7 ± 13. 5μm, 132. 7 ± 17. 4μm/128. 1 ± 25. 3μm, 83. 7 ± 22. 3μm/76. 5 ± 17. 8μm, 141. 5 ± 15. 3μm/128. 6± 13. 2μm, 117. 9 ± 24. 5μm/103. 3 ± 14. 1μm, 120. 8 ± 21. 2μm /102. 6 ± 23. 7μm, 110. 2 ± 27. 7μm/96. 6 ± 15. 0μm, 109. 6 ± 20. 6μm/101. 2 ± 20. 9μm. The average RNFL thickness in controls was 109. 9 ± 8. 5μm while it showed 102. 3 ± 11. 9μm in PD group. RNFL thickness in inferior, temporal, inferior-temporal, superior-temporal and the average RNFL thickness were statistically different in two groups ( t= 2. 595, 2. 700, 2. 153, 2. 330, 2. 131;P= 0. 014, 0. 011,0. 040,0. 026,0. 041).?CONCLUSlON: RNFL thickness in inferior, temporal, inferior temporal, superior temporal and the average RNFL thickness are significantly thinner in mild PD than those in the controls.

Intracranial artery stenosis is one of the main causes inducing transient ischemic attack (TIA) or cerebral ischemic stroke. Being a minimally-invasive and reliably-effective technique, intracranial artery stent angioplasty has brought about a new approach for the treatment of intracranial artery stenosis , and thus provides more opportunities to the patients who are not suitable for intracranial vascular bypass surgery. However, the higher occurrence of perioperative complications caused by stent angioplasty should be seriously taken into consideration by clinical physicians. In order to reduce the occurrence of complications , in this paper the perioperative complications of stent angioplasty for intracranial artery stenosis are analyzed , and the therapeutic strategies as well as the proper approaches are discussed.

There are many problems existing in humanities and social science courses in education and teaching of medical colleges and universities.Changing concepts of education,adjusting the curriculum,improving teaching methods and improving the quality of teachers are effective measures in medical colleges to strengthen the humanities and social science courses.We have made a preliminary exploration on teaching practice for humanistic education and professional education.

Absrtact: Osteoarthritis (OA) is a most common form of degenerative joint disease, primarily characterized by the degradation of articular cartilage, subchondral sclerosis and inflammation of the synovial membrane. Mesenchymal stem cells (MSCs), a multipotent adult stem cell population, can be isolated from many connective tissue lineages, including those of the diarthrodial joint. Joint-resident MSCs or MSC-like progenitor cells contribute to the maintenance of healthy microenvironment or to the response to trauma. The onset of degenerative changes in the joint related to abnormal condition or depletion of these endogenous MSCs and native host hyaline cartilage cells, leading to limited self-repair potential of the joint and advance of the degradation. To date, no acknowledged medical treatment strategies, including non-operative and classical surgical techniques, are efficient in restoring normal anatomy and function of hyaline cartilage in OA. This highlights an urgent need for better celled-based therapeutic strategies that supplement these functional cells exogenously to recover the tissue homeostasis and repair in joint cavity via chondrogenic and anti- in fl ammatory functions. In this review we focus on the role of native MSCs in healthy or OA joint and recent progress in cell-based researches utilizing culture-expanded chondrocytes, pluripotent stem cells, or MSCs from different sources for treating OA.

Objective To delineate the potency of YC-1 on the proliferation,apoptosis,cell cycle and the protein expression of Caspase-3,-8,-9 in U937 and THP-1 leukemia cell lines.Methods MTT assay was performed to detect proliferation.Flow cytometry was used to measure the apoptosis and cell cycle.The expression of Caspase-3,-8 and-9 were detected by Western blot.Results The MTT assay showed that cell proliferation was inhibited in a concentration-dependent manner in 1.0,3.0,10.0 μmol/L YC-l-treated U937 and THP-1 cells.The survival rates for YC-1 after 24 h in U937 cells were (76.5±4.4) ％,(68.7±6.8) ％,(60.9±13.2) ％ respectively and (94.1±1.4) ％,(81.4±2.0) ％,(72.7±3.0) ％ respectively in THP-1 cell,compared with the control group (100 ％),there were significant differences (F =15.870,126.629,P ＜ 0.01).The apoptosis rates for 1.0,3.0,10.0 μmol/L YC-1 after 24 h were (40.7±1.0) ％,(55.6±2.3) ％,(71.8±1.5) ％respectively in U937 cells and (34.6±2.0) ％,(50.3±3.5) ％,(59.6±4.6) ％ respectively in THP-1 cells.With the control group (4.7±1.4) ％,(1.8±1.0) ％,there were significant difference (F =937.229,200.447,P ＜ 0.01).However,there was no significant difference for cell cycle.In addition,Cleaved Caspase-8 and Cleaved Caspase-3 expression after 1.0,3.0,10.0 μmol/L YC-1 treated for 24 h were significantly higher than control,but the expression of Caspase-9 did not appear significant change in U937 cells.As the same concentration and time point,Cleaved Caspase-3 expression increased with no change of Caspase-9 or Caspase-8 in THP-1 cells.Conclusion YC-1 effectively suppress the proliferation with little effect on cell cycle,but induce the apoptosis,have no effect on cell cycle,and the mechanism of apoptosis may be related to the Caspase activation in U937 and THP-1 cell lines.

Objective To evaluate the clinical application and therapeutic effect of interventional embolization in treating renal pseudoaneurysms. Methods The clinical data of 11 patients with renal pseudoaneurysm, who had received interventional embolization management at authors’ hospital, were retrospectively analyzed. The embolic agents used in the embolization procedure included conventional steel coil, gelatin sponge particles, PVA, etc. All the patients were followed up for 6-24 months. Results Single renal pseudoaneurysm was found in all the 11 patients. Clinically, symptom of bleeding was seen in 3 cases. The renal pseudoaneurysm was located at the upper (n=1), middle (n=4) and lower (n=5) renal artery of the kidney, and in one case the renal pseudoaneurysm was situated at the accessory renal artery. In performing renal artery embolization, pure PVA was used in one case, spring steel coil in one case, PVA together with spring steel coil in one case, and gelatin sponge combined with spring coil in 8 cases. After the embolization, the pseudoaneurysm was no more visualized, the contrast extravasation disappeared, and the parent artery was manifested as a residual root. During the operation the patients had no obvious discomfort. Within one week after embolization therapy, 2 patients developed hemorrhage, and their hemoglobin, white blood cell count and hematocrit were significantly increased. During the follow-up period, all patients showed no recurrence signs, and routine urine tests were normal. Conclusion For the treatment of renal pseudoaneurysms, interventional embolization is minimally-invasive, safe and reliable; this technique can maximally protect the normal kidney tissue, quickly control the bleeding and effectively save the life of patient. Therefore, it is worth promoting this treatment in clinical practice.
