The incidence of venous thromboembolism after spinal cord injury is high, and its diagnosis and prevention received much attention in clinical research in recent years. Because of the special characteristics, the prevention of venous thrombosis should be combined with basic prevention, physical prevention and drug prevention. According to the different situations of venous thromboembolism in patients with spinal cord injury, the prevention methods need to adjust to carry out multidisciplinary comprehensive treatment.

Purpose Two kinds of forward conditional reasoning including modus ponens (MP) and denial of the antecedent (DA) are the most common deductive reasoning in daily life. The present study aimed to explore the difference between the two neural machanisms. Materials and Methods Three kinds of tasks including MP, DA, and baseline were administrated to 14 undergraduates [7 males and 7 females, mean age (23.4±1.3) years] by using functional magnetic resonance imaging (fMRI) technique. fMRI data was analyzed. Results The reaction times were significantly slower for MP and DA than that of BS (P<0.001), while the effect was not significant for accuracy. In contrast to baseline, both MP and DA tasks activated the left inferior frontal cortex (BA 9), inferior parietal lobule (BA 40), and postcentral gyrus. Bilateral caudate significant activation was found in MP task when compared with DA, whereas the frontal, parietal, occipital lobe and anterior cingulate cortex were acivated more in the DA than in MP task. Conclusion Both forward conditional reasoning of MP and DA commonly activate the left frontoparietal cortex, while significant dissociations can be seen in the regions of caudate and bilateral frontal, parietal and occipital. These results firstly demonstrates the different neural mechanism underlying the two forward conditional reasoning, which might help to further uncover the brain mechanism of conditional reasoning.

Objective To study the effects of helicase-like transcription factor (HLTF)transfection on DNA repair protein level in radiation-induced apoptotic cells.Methods Human lung carcinoma A549 cells were cultured and transfected with FLAG-tagged wild type HLTF (wild type HLTF transfection group),RING structure domain (ubiquitin conjugating region) mutatation HLTF expressing plasmid (mutant transfection group),empty plasmid (congtrol group) respectively.And the other cells were used as mock transfection group.All cells were irradiated with 15 Gy of 60Co γ-rays to induce apoptosis.Western blotting was used to detect the protein levels of the DNA repair proteins HRAD17 and HRAD52 in the transfected cells.Results The levels of HRAD17 and HRAD52 in the wild type HLTF transfection group was significantly lower than that of the control group.There was no significant difference in HRAD17 and HRAD52 levels between the mock transfection group and ubiquity in conjugating region mutation group.complexes of HLTF and HRAD17 and HRAD52 could be found in the irradiation-induced cells.Conclusions HLTF mediates the degradation of HRAD17 and HRAD52 in the irradiation-induced apoptotic cells possibly by the interaction of the protein complex causing ubiquitination of the repair proteins.

The amount of acupuncture treatment refers to the sum of acupuncture effects during the treatment. From the factors that constitutes the amount of acupuncture treatment, including the numbers of needling, the size of acupuncture instruments, the depth of acupuncture, the manipulation, the retained time of needle, etc., and combined with teaching and clinical experience, it is believed that the amount of acupuncture treatment is closely related with clinical efficacy, besides, moderate amount of acupuncture treatment is a key factor to improve acupuncture efficacy and guarantee the safety of acupuncture. The basic principles of regular treatment amount are arrival of qi and being moderate, indicating the retained time of needle, treatment frequency and course should be based on individual condition, time, location and disease.

BACKGROUND: Interlocking nail implantation exhibits great stability and preventory effect on fracture shortening or rotation.OBJECTIVE: To evaluate the reasons and countermeasures for the complication after interlocking nail implantation in treating femoral fracture.DESIGN, TIME AND SETTING: The case analysis was performed at Department of Orthopedics, Changhai Hospital of Second Military Medical University of Chinese PLA from April 1987 to April 2008.PARTICIPANTS: 352 patients underwent femoral interlocking nail implantation, including 289 male and 63 female with an average age of 35.9 years (range 18-84 years).METHODS: 127 patients were treated with close interlocking nail implantation, of which 30 cases were subjected to minimal incision to assist nail insertion; 24 were treated with dynamic interlocking nail implantation; 321 with static interlocking nail implantation, and 38 with interlocking nail implantation for femoral reconstruction.MIAN OUTCOME MEASURES: Complications post-implantation; limb joint function recovery during long-term follow-up.RESULTS: 331 cases were followed-up for over 60 months, and the longest follow-up lasted for 252 months. Complications were found in 16 cases, including deformity union in 2, femoral neck fracture in 1, exit of the nail in 2, infection in 2, breakage in 8 (nonunion in 3), and perineal nerve injury in 1. Except 2 with deformity union and recovered by secondary surgery, all patients developed bone union. During the followed-up, no pain or knocked pain was found with normal pseudoarthrosis activities and functional activities. The excellent function recovery in joints and limbs was 91.2%.CONCLUSION: Nail breakage is the main complication after interlocking nail implantation. Therefore, we should select longer and thicker interlocking nail as the first choice. In addition, the interlocked screws should be distal to fracture site. For the patients with severe trauma, the interlocking nail implantation in early stage of fracture would not increase complications.
