Objective To investigate the effect of internal fixative operation with special-shaped plate on Pi- lon fracture.Methods 84 cases of Pilon fracture were treated respectively by continuous skeletal traction of calca- neus,internal fixative operation with general steel plate or Kirschner wire,or internal fixative operation with special- shaped plate.Results All the cases were followed up for 6 months to 2 years postoperatively.The rate of being ex- cellent and fine of 3 groups treated by 3 different methods was 42%,61% and 72 % separately.Conclusion Inter- nal fixative operation with special-shaped plate is a good way to treat Pilon fracture for its less complication and more recuperation and retention of function for anklebone.

Journal of Applied Clinical Pediatrics 2006;0(14):-
Objective To explore the clinical value of respiratory index(RI) and oxygenation index(OI)dynamic monitoring in neonatal respiratory distress syndrome(NRDS) during mchanical ventilation.Methods According to prognosis,24 newborns with NRDS who had not be treated with pulmonary surfactant in NICU of Chengdu maternal and child health hospital from Dec.2006 to Nov.2007 were divided into 2 groups.There were 16 newborns in survival group and 8 newborns in death group.The changes of RI,OI,p(A-a)(O2) and pa(O2) were stu-died at 2,24,48 h after using of synchronized intermittent mandatory ventilation and before ventilation weaning.Results In the early periods,there were significant differences in RI,OI and p(A-a)(O2) between the survival group and the death group(t=2.47,2.62,3.01 Pa

Objective To explore the anatomy and the adjacent of the medial malleolus,the operative approach of soluting the tibial nerve in endoscopy and the significance of making use of it in operation. Methods The five cadaver feet were dissected,the tibial nerve and the fiber diaphragm in the middle of me- dial and lateral plantar tunnels in the ten cadaver feet were soluted in endoscopic.Results The operative approach was designed on the basis of the anatomy data (the three-portal approach:The perpendicular bisetor which was the medial malleolus pointed to the medial margin of tendon calcaneus insertion was 4.5cm;The midpoint of the medial malleolus pointed to the calcaneus tubercle;The midpoint of the calcaneus tubercle to the medial margin of the first metatarsophalangeal joint).It was succeed that soluted the tibial nerve and the fiber diaphragm in the middle of medial and lateral plantar tunnels.Conclusion The operative approach on the basis of the anatomy data is design,and testfy the feasibility of exploring curved tunnel in endoscopic.

AIM:To evaluate the efficiency of vitrectomy combined with inferior scleral buckling for a special kind of retinal detachment.
METHODS: Nineteen eyes of special retinal detachment had following features: 1 ) the course was more than 6mo;2) there were at least one hole located in the 5 : 00 - 7 : 00 of the marginal retina; 3 ) the detachment range of retina more than 270 degrees and retinal proliferation in retinal detachment. The 19 eyes who received vitrectomy combined with inferior scleral buckling, retinal anatomic reattachment and visual function recovery was observed.
RESULTS: Among these 19 eyes, all eyes retinal anatomic reattachment and best corrected visual acuity ( BCVA ) was improved in various degrees. The BCVA was 0. 01-0. 1 in 5 eyes, 0. 12-0. 3 in 9 eyes, and ≥0. 4 in 5 eyes.
CONCLUSION: It is an effective method to vitrectomy combined with inferior scleral buckling for the special kind of retinal detachment which has following features:1) the course was more than 6mo;2) there were at least one hole located in the 5:00-7:00 of the marginal retina;3 ) the detachment range of retina more than 270 degrees and retinal proliferation of cable in retinal detachment.

Objective To investigate the protective effects of hypereapnia on acute lung injury(ALI)in an model of rabbits in vivo,and to observe its effect on oxygen free radicals in the lung tissue in order to uncover the potential mechanisms.Method In the laboratory of pharmacology,China Medical Univereity,twenty-two healthy New Zealand white rabbits were randomly assigned to control group(Group C,n=6)with the injection of normal saline(0.1 ml/kg),and sixteen rabbits were injected with oleic acid(0.1ml/kg)intravenously,and then were randomly dirided into normocapnia group(Group N,n=8)and hypercapnia group(Group H,n=8,FiCO2=8%).Then tracheostomy was performed,and the experimental animals were ventilated for 3 hours after oleic acid or sterile normal saline administration.Lung mechanics,hemodynamics,blood-gas analysis were monitored.The rabbits were exsangninated.and the lungs and heart were taken out from the thorax.The concentration of superoxide dismutase(SOD)and malondialdehyde(MDA)in the lung tissue were assayed.Lung tissue wet/dry ratio and pulmonary permeability index were measured and histologic damage was assessed after three hours'mechanical ventilation.Results Peak airway pressure in Group H was significantly lower than that in Group N and the dynamic lung comphance Was significantly higher than that in Group N(P<0.05).PaO2 in Group H was significantly higher than that in Group N(P<0.05).The concentration of MDA in the lung tissue in group H was significantly lower than that in Group N(P<0.05),and SOD in group H was significantly higher than that in Group N(P<O.05).Lung tissue wet/dry ratio and pulmonary permeability in group H were significantly lower than that in Group N(P<0.05).Histological tissus damage in Group N wassignificantly severer than that in Group H.Conclusions Hypercapnia induced by inhalation of high concentration of carbon dioxide(8%)plays protective role in this in vivo model of ALI.The mechanisms may be associated with enhanced SOD activity and the attenuation of lipid peroxidation in the lung tissue.

AIM: To investigate whether hypercapnia is protective against acute lung injury (ALI) in a rabbit model, and study it's potential mechanisms. METHODS: Twenty-two healthy New Zealand white rabbits were involved in this study, and randomly allocated to control group (group C), normocapnic group (group N) and hypercapnic group (group H). Oleic acid (0 1 mL/kg) was injected intravenously to establish ALI model. Lung mechanics, hemodynamics, blood-gas analysis, the content of malondialdehyde (MDA) and superoxide dismutase (SOD) activity in lung tissue were measured. Apoptosis was analyzed after 3h mechanical ventilation. RESULTS: (1) Peak airway pressure in group H was significantly lower than that in group N (P
