1.Immunohistochemical analysis of neuropeptide Y in the Bullfrog Retina
Journal of Third Military Medical University 2003;0(20):-
Objective To investigate the distribution and synaptic connectivity of neuropeptide Y (NPY)-like immunoreactivity (IR) in Bullfrog retina, Rana Calesbeiana, especially in the inner plexiform layer. Methods Light microscopy immunofluorescence and post-embedding colloidal gold labeling electron microscopy techniques were employed in this study. Results NPY immunoreactivity was associated with a small population of amacrine cell bodies in the inner nuclear layer and cell processes, ramified with 3 distinct bands, in the inner plexiform layer. As for ultrastructure, quantitative analysis showed that NPY-IR amacrine cell processes were most often presynaptic to NPY negative amacrine cell processes (49.7%) and ganglion cell dendrites (49.3%). NPY-IR amacrine cells predominantly received synaptic input from bipolar cell axon terminals (86%), while a few input from other amacrine cell processes (14%). Conclusion NPY-IR in Bullfrog retina is mainly distributed in the inner part and predominately receives excitatory glutamate modulation from bipolar cells.

5.Theoretical hypothesis and clinical practice of Bobath concept: A therapeutical basis for nervous tissues repairing and functional reconstruction
Chinese Journal of Tissue Engineering Research 2010;14(2):341-346
OBJECTIVE: A series of Bobath concept, Bobath theoretical hypothesis and clinical practice were summarized, to proVide a better understanding of Bobath concept involved in nervous tissues repairing and functional reconstruction. METHODS: Articles concerning the Bobath treatment for stroke-related literature were retrieved in Highwire press, MEDLINE, and Google from 2001 to 2009, using the key words of "Bobath concept, stroke physical therapy". Data of each study were extracted and analyzed following retrieval. Inclusion criteria:①Bobath concept and its theoretical hypothesis. ②New development of Bobath concept in clinical practice. Exclusion criteria: Repetitive studies. The results of retrieved literatura were analyzed. RESULTS: The theoretical basis of Bobath concept is based on present-day knowledge of motor control, motor learning, neural and muscle plasticity, and biomechanics. The latest theories and viewpoints are rasourced from International Bobath Instructors Training Association and the British Bobath Tutors Association. They expounded on the Bobath concept from linking participation, activities and underlying impairments, organization of human behavior and motor control, the consequences of injury and dysfunction in the execution of movement, neural and muscle plasticity, motor learning and so. This article also discusses several important questions which meet in clinical practice. CONCLUSION: Bobath therapy, as a traditional method for stroke rehabilitation, is constantly absorbing the research results from current neuroscience, psychology and other disciplines, and blended with other treatments to promote the development of neuro-rehabilitation medicine.
6.Directional cartilage scaffold for the repair of articular cartilage injury caused by exercise
Chinese Journal of Tissue Engineering Research 2017;21(2):209-214
BACKGROUND:Cartilage scaffold plays an important role in articular cartilage injury, but it is stil restricted in practice, leading to the repair failure using tissue-engineered cartilage. OBJECTIVE:To explore the preparation method of cartilage scaffold with directional structure and its repairing effect in cartilage injury of rabbits. METHODS:Directional cartilage scaffolds were prepared by temperature gradient induced phase separation technique. The cross-linking of cartilage scaffold was completed with genipin. The physical and mechanical properties of scaffolds were determined. Forty-eight white rabbits were modeled into exercised-induced articular cartilage injury and equivalently randomized into two groups, fol owed by implantation of non-directional or directional scaffolds. Samples were col ected at postoperative 6, 12 and 24 weeks to compare the repair effect of two scaffolds on rabbit joint injury. RESULTS AND CONCLUSION:Scanning electron microscope showed that the regular microstructures on the longitudinal section of directional scaffolds were aligned in the same direction, while the longitudinal and transverse planes of the non-directional scaffolds showed porous honeycomb structures. The elastic modulus of the directional scaffold was significantly higher than that of the non-directional scaffold (P<0.05). O’Driscol histological scores in the directional scaffold group were significantly higher than those in the non-directional scaffold group at 6, 12 and 24 weeks postoperatively (P<0.05). At postoperative 24 weeks, in the directional scaffold group, the three-dimensional reconstruction of the rabbit defect region was flat and smooth, and coronal two-dimensional scanning showed the cartilage thickness of the newborn cartilage was very close to that of the normal bone;the cartilage surface in the non-directional rabbits was flat under three-dimensional CT, and coronal two-dimensional scanning showed that the repaired cartilage was almost the same as the normal cartilage. Hematoxylin-eosin staining showed that at 24 weeks postoperatively, the defect site disappeared and the cartilage cel s arranged in the vertical direction in the directional scaffold group. There were typical cartilage lacunae at the defect site in the non-directional scaffold group at 24 weeks postoperatively. Our findings suggest that the directional cartilage scaffold prepared using temperature gradient induced phase separation technique holds good physical and mechanical properties, and its implantation into the rabbit articular cartilage injury induced by exercise can promote the injury repair to obtain ideal mechanical properties.

Conclusion : The experimental results provided the basis for the ascertainment of extraction process of Rhizoma Coptidis and Herba Ephedrae preparation.
9.Complication of acute cerebral infarction and management
Chinese Journal of Practical Internal Medicine 2000;0(11):-
Complications that follow ischemic stroke are common,frequency ranging from 28% to 95%.It may either directly lead to death or prevent optimal recovery.54% of deaths after ischemic stroke are attributed to medical complications.Most complications occur during the first week,and stroke severity is the most important risk factor.The common serious medical complications are chest or urinary tract infection,deep venous thrombosis,pulmonary embolism,cardiac events,gastrointestinal bleeding,hyperglycemia,pressure sores.Falls,shoulder pain and depression are also common complications.Most of medical complications are preventable or treatable to some extent if recognized,so preventive strategies and appropriate treatment should be employed as early as possible.Prevention,early recognition,and management complications could improve short-term and long-term prognoses after ischemic stroke.
