Objective To investigate the respiratory function of platelet mitochondria in patients with Parkinson's disease(PD) and explore the assosiation with the pathogenesis of PD.Methods The platelet mitochondria of 35 patients with PD were extracted and the mitochondria respiratory rate and respiratory control rate were measured.Furthermore,the changes of activities of mitochondria complex Ⅰ,Ⅱ,Ⅲ and Ⅳ were observed.Results The platelet counts of patients with PD showed no changes, but the respiratory rates of respiratory state 3 were significantly decreased using the 5 mmol/L glutamate,2.5 mmol/L malate +5 mmol/L pyruvate and 5 mM succinate as substrates. Moreover, the activities of mitochondria complex Ⅰ were obviously reduced and the activites of other mitochondria complex were no changes.Conclusion Patients with PD show exactly abnormal mitochondria respiratory functions, and it might be an important mechanism in the pathogenesis of PD.

Objective To observe the function changes of right ventricular in chronic obstructive emphysema after lung volume reduction surgery. Methods Twenty-six patients with chronic obstructive emphysema undergoing lung volume reduction surgery were examined by color Doppler echocardiography to determine systolic function and diastolic function of right ventricle in preoperative days and postoperative days of 5～7; 12～14; 1 month and 3 months. Results Contraction of right ventricle: comparing with preoperative parameters, there were significant decrease (P0.05) of those above mentioned in postoperative days 12～14. It recovered at 3 month after operation. Relaxation of right ventricle: the swift filling peak flow-rate in earlier relax period (E) and E flow-rate integra (ETVI) decreased meanwhile swif filling peak flow-rate in late relax period (A) and A flow-rate integra (ATVI) increased in the postoperative days 5～7 (P

Objective: To establish a Beagle dog model for the study of the mechanism of implant-bone interface remodeling following the restoration of submerged and nonsubmerged implant denture. Methods: 8 adult purebred beagle dogs were used to build the animal model. Fixed metal full crown was used to carry out submerged and nonsubmerged implant denture in the dogs to mimic the normal chewing status in animal models. Results: The submerged and nonsubmerged implant dentures were made successfully. After the implant denture restoration, all experimental dogs were fed with granular horniness forage to guarantee enough biting stimulation. The chewing fashion of experimental dogs was not changed obviously during the experiment process. Although the horniness forage may result in fairly bigger bite force, no visble biting hurt was found 12 weeks after loading and the fixed implant dentures were all preserved. Conclusion: The beagle dog model can preferably mimic the normal chewing fashion and the models are both availability and credibility.

Objective: To study the implant-bone interface remodelin g after loading of submerged and nonsubmerged implant denture.Methods: 8 adult beagle dogs were used to build the animal model. Submerged and nons ubmerged implants were implanted into the bilateral mandible. Fixed metal full c rown was used to carry out the submerged and nonsubmerged implant denture. The b eagle dogs were sacrificed by steps after loading of the dentures. HE staining t echnique was used to observe the dynamic remodeling process of implant-bone int erface.Results:2 weeks after loading of implant denture, a major ity of the implant surface attached to bone tissue directly, however, at the int erface, especially at the top of the screw thread, bone tissues were absorbed an d substituted by fibrous tissues. 4 weeks after loading, fine attachment was fou nd at the implant-bone interface and the previouly observed fibrous tissue at t he interface was gradually remodeled to form new bone. 8 weeks after loading, i mplant directly attached to bone tissues by osteo-interface, and the cellular c omponents and capillaries were decreased at the interface.12 weeks after loading , all implants attached to bone tissues by osteo-interface with high combinatio n level, typical Havers system was observed at the interface.No obvious differen ce in the interface remodeling was observed between the submerged and nonsubmerg ed implant denture. Conclusion:There is no distinct difference i n the implant-bone interface remodeling after the loading of submerged and nons ubmerged implant denture.

AIM: To compare the clinical outcomes of pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells or transplantation of conjunctival autograft with stem cells to treat and prevent the recurrence of pterygium.METHODS: Fifty patients (60 eyes) were divided into 2groups, and pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells (group A) and pterygium excision followed by transplantation of conjunctiva autograft harvested from counter-side limbus with stem cells (group B) were performed respectively.The surgical time of each case was recorded.RESULTS: All the 50 cases (60 eyes) of pterygium were recruited. The epithelization of cornea and conjunctiva in all cases finished in 2-5d, During the follow-up of 6-12mo, pterygium reoccurred in 2 cases (1 in each group), with no difference in recurrence rate. The mean surgical time was 25± 8min for group A,43± 11min for group B, the difference being statistically significant (P＜0.05, t-test).CONCLUSION: Both methods, pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells or transplantation of conjunctival autograft with stem cells are effective on treating and reducing the recurrence of pterygium. Compared with the latter, pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells is simpler and easier to perform, and is preferred by the patients too.
