Objective To analyze the potential risk factors of sudden death at home in senile people. Methods 38 cases of cardiac arrest in a community occurring at home from 1993 to 2004 were retrospectively analyzed. The data concerning their condition of health before death, the diagnosis of the diseases confirmed, the predisposing causes of cardiac arrest, and the season and time of death were collected and analyzed. Results It was found that hypertension, CHD and diabetes were the predominant diseases in senile patients died of out-of-hospital cardiac arrest. Most of the deaths occurred in April, 73.7% of the deaths occurred during 6:00-18:00, and 81.6% cases occurred in their homes. Conclusion In senile patients, the cardiovascular diseases may be the main risk factors of out-of-hospital cardiac arrest. The patients with myocardial infarction, arrhythmia and heart failure constitute the high risk group of cardiac arrest. Usually death occurs without a portent.

Objective:To study the effects of vitamin C (VC) on the injury of alveolar macrophages exposed to Ni2O3 in vitro and the expression of inducible nitric oxide synthase (iNOS). Method:The alveolar macrophages were cultured with exposure to Ni2O3 in vitro. Meanwhile,VC with different concentrations (25,50 and 100 ?mol/L) were added to the medium, respectively. The cell activity,nitric oxide(NO),reactive oxygen species (ROS), malondialdehyde (MDA) and activities of SOD, GSH-Px,CAT and iNOS were detected. iNOS mRNA expression was detected by using RT-PCR. Results:VC could decrease mortality and increase survival activity of alveolar macrophages. VC could also decrease ROS,NO and NOS activity,increase SOD,GSH-Px, CAT activities and downregulate the expression of iNOS mRNA. Conclusion:The lipid peroxidation of alveolar macrophage could be induced by Ni2O3. VC could downregulate the expression of iNOS mRNA and reduce the production of ROS and NO through increasing the activity of antioxidative enzymes and antagonize the oxidative damage induced by Ni2O3.

Objective:To investigate surgical methods and clinical effects of tibial pseudarthrosis due to neurofibromatosis type I (NF1) in adult using Ilizarov technique combined with intramedullary nail.Methods:A total of 12 adult with tibial pseudarthrosis due to NF1 treated by Ilizarov technique combined with intramedullary nail from October 2009 to December 2017 were retrospectively included. There were 6 males and 6 females with an average age of 27±8.3 years (range 17-44). All cases presented severe anterior arch in varus or valgus deformity with shortening in an average of 10.8±3.7 cm (range 5.6-16.5 cm). The in-volved levels were at the middle and lower part of tibia. All cases suffered from more than one treatment with failed surgery. One male patient with 5 times of unsuccessful operations. There were 4 cases with severe limping gait and 8 cases with walking with the help of brace (or single crutch) preoperatively. Regarding the family history, seven cases were inherited by father and 5 cases by mother. During surgery, the part of tibial pseudarthrosis and thickened fibrous tissue surroundings like periosteal were removed. The contracture achilles tendon was elongated in open way, and intramedullary nailing cross the ankle joint was applied when the tibial medullary cavity opened. Further, iliac bone grafting and proximal tibial osteotomy were performed with Ilizarov fixator application finally. The tibia was lengthened at a rate of 0.5-1 mm/d at 7 days postoperatively. The healing rate of pseudarthrosis and the length and alignment of limb were evaluated by X-ray routinely. The lower limb function and complications were assessed by self-made table for lower limb deformity correction and functional reconstruction.Results:All patients were followed up for 31-80 months with an average of 47.6±14.7 months. Bone union of pseudarthrosis in all cases was eventually achieved. The tibia was lengthened 5-12 cm with an average of 8.4±2.5 cm. There were 9 cases underwent second surgeries to promote bone healing and to correct residual deformities. The external fixator was used for 25-37 months with an average of 31.5±3.7 months. There was no complication, including neurovascular injury, severe soft tissue or bone infection affecting the clinical effects. All intramedullary nails were not removed finally. The limb function and gait in full weight bearing in 12 patients recovered at the latest follow-up. The evaluation score was 2.4±0.3 (range 2.1-2.8), of which 9 cases were excellent 3 were good. Thus, the excellent and good rate was 100%.Conclusion:The satisfactory clinical effects, including angular deformity correction, pseudarthrosis healing and short limb lengthening, can be achieved in adult with tibial pseudarthrosis due to NF1 by using the combination method of Ilizarov technique and intramedullary nail. However, the treatment duration could be longer.
