RESUMEN
OBJECTIVE@#To explore clinical effect of internal and external fixation combined with second-stage perforator fiap for the treatment of ankle fracture dislocation of Gustilo-Anderson types ⅢB and ⅢC.@*METHODS@#From May 2014 to July 2017, 20 patients with Gustilo-Anderson types ⅢB and ⅢC ankle fracture dislocation were treated with internal and external fixation combined with second-stage perforator fiap, including 14 males and 6 females, aged from 18 to 58 years old with an average of (39.0±9.7) years old;17 patients were type ⅢB and 3 patients were type ⅢC according to Gustilo-Anderson classification;4 patients were type A, 7 patients were type B, and 9 patients were type C according to AO classification. The size of wound ranged from 4 cm×3 cm to 20 cm×9 cm. Second-stage perforator flap, 11 patients were performed with posterior tibial artery perforator flap, 5 patients were performed with fibular artery perforator flap, 1 patient was performed with anterior ankle flap, and 3 patients were performed with posterior tibial artery perforator flap combined with fibular artery perforator flap. Postoperative wound healing, flap survival and fracture healing were observed, AOFAS score was used to evaluate at the latest follow up.@*RESULTS@#All limbs were preserved successfully without amputation. Nine patients occurred superficial infection without deep infection and osteomyelitis occurring. The flaps of 19 patients survived. All patients were followed up for 6 to 18 months with an average of (12.0±2.9) months. The flaps healed well without sinus tract, bone exposure and bone disunion occurring. Fracture healing time ranged from 4 to 10 months with an average of (6.6±1.7) months. PostoperativeAOFAS score was 76.7± 16.4, among which 4 patients got excellent result, 11 patients good, 3 patients fair, and 2 poor.@*CONCLUSION@#Internal and external fixation combined with second stage perforator fiap for the treatment of ankle fracture dislocation of Gustilo-Anderson types ⅢB and ⅢC could effectively close the wound, improve fracture healing and restore appearance and function of limbs to the maximum.

OBJECTIVE@#To study the clinical effect of the oxygen drive aerosol in halation with budesonide and ambroxol in the prevention of adult post-thoracotomy pneumonia.@*METHODS@#This was a randomized, open and parallel controlled trial. We chose 80 cases of patients in the department of thoracic surgery in the First Affiliated Hospital of Xi'an Jiaotong University which fitted our criteria as the research object. The selected patients were randomly divided into the active group and the control group, and the active group underwent oxygen drive aerosol inhalation (2 mg budesonide combined 60 mg ambroxol) for 3 days before operation, and the control group without preoperative aerosol inhalation, and their postoperative therapy was the same.@*RESULTS@#The baseline data showed that the differences in sex, age, disease and smoking were not statistically significant between the two groups, P>0.05. The results of blood gas analysis before 12 hours of operation suggested that, the PaO₂and PaCO₂values of the active group were (88.40±9.40) mmHg and (38.30±6.10) mmHg; The PaO₂and PaCO₂ values of the control group were (85.09±7.18) mmHg and (41.21±3.15) mmHg. And the two groups' P values were 0.029 and 0.011, with statistical differences. There were 3 patients who developed postoperative pneumonia out of 40 patients in the active group, the incidence was 7.50%, but the incidence of control group was 25.00%. The P value was 0.034, with statistical differences. We also analyzed the influence of different diseases and surgical methods on postoperative pneumonia, and the results showed that in the active group and the control group, the incidence of postoperative pneumonia in the patients with esophageal cancer was lower than that in lung cancer patients, and there was a statistically significant difference (P<0.05). In the active group, the numbers of pulmonary deed resection, lobectomy and pulmonary sleeve resection were 2, 21 and 1 cases respectively, and the corresponding numbers in the control group were 2, 21 and 2. Among the two groups, the incidence of postoperative pneumonia in the patients with different surgical methods of lung cancer was statistically significant (P<0.05).@*CONCLUSION@#If we implement respiratory preparation with budesonide plus ambroxol inhalation for 3 days before operation, we can greatly reduce the incidence of postoperative pneumonia?

<p><b>BACKGROUND</b>Elevated fibrinogen (Fg) level is a known risk factor for ischemic stroke. There are few clinical trials on oral fibrinogen-depleting therapies for secondary ischemic stroke prevention. We aimed to assess the effects of one-year therapy with oral lumbrokinase enteric-coated capsules on secondary ischemic stroke prevention.</p><p><b>METHODS</b>This is a multicenter, randomized, parallel group and controlled study that began treatment in hospitalized patients with ischemic stroke and continued for 12 months. Patients were randomized to either the control group that received the standard stroke treatment or the fibrinogen-depleting group that received the standard stroke treatment plus enteric-coated lumbrokinase capsules. The NIH Stroke Scale scores (NIHSSs) and plasma Fg level were recorded. The carotid artery intima-media thickness (IMT) and status of plaques were examined through carotid ultrasound examination. Primary outcomes included all-cause mortality, any event of recurrent ischemic stroke/transient ischemic attack (TIA), hemorrhagic stroke, myocardial infarction and angina, and other noncerebral ischemia or hemorrhage. Kaplan-Meier survival analysis and the Long-rank test were used to compare total vascular end point incidence between the two groups. Comparison of median values between two groups was done by the Student t test, one-way analysis of variance (ANOVA), or non-parametric rank sum test.</p><p><b>RESULTS</b>A total of 310 patients were enrolled, 192 patients in the treatment group and 118 patients in the control group. Compared to the control group, the treatment group showed favorable outcomes in the Fg level, carotid IMT, the detection rate of vulnerable plaques, the volume of carotid plaques, NIHSS scores, and incidence of total vascular (6.78% and 2.08%, respectively) and cerebral vascular events (5.93% and 1.04%, respectively) (P < 0.05). In the treatment group, the volume of carotid plaques was significantly related to the carotid IMT, the plaque diameter, width and number (P = 0.000, 0.000, 0.000, 0.022; F = 13.51, 2.52, 11.33, -3.29, but there was a weak correlation with the Fg level (P = 0.056). After 1-year therapy, the incidence of overall vascular end points was reduced by 4.7%.</p><p><b>CONCLUSION</b>Long-term oral fibrinogen-depleting therapy may be beneficial for secondary ischemic stroke prevention.</p>

<p><b>OBJECTIVE</b>To evaluate the feasibility and efficiency of embolization of spinal dural arteriovenous fistula (SDAVF).</p><p><b>METHODS</b>From December 2010 to May 2012, there were 104 cases of SDAVF were treated, and 26 cases were selected to be treated with embolization. The inclusion criteria was as follows: (1) No anterior or posterior spinal artery originated from the fistula segment; (2) The segmental artery can be catheterized with guiding or micro catheter; (3) High flow in fistula; (4) Patient's situation was not suitable for surgery or general anesthesia. Among 26 cases, there were 22 male and 4 female patients, the average age was 55.9 years (ranged from 34 to 81 years). The locations of SDAVF were 10 cases in thoracic, 9 in lumbar and 7 in sacral segment. The main symptoms were progressive numbness and weakness in both lower extremities, most cases accompanied with difficulties in urination and defecation. The average history was 17.1 months (from 1 to 156 months). ONYX-18 liquid embolic agent or Glubran-2 surgical glue were used as embolic material. The patients not cured with embolization were treated with surgery in the following 1 - 2 weeks. Follow-up evaluation was done with MRI after 3 months and DSA after 6 months, besides physical examination.</p><p><b>RESULTS</b>Fifteen from 26 cases achieved immediate angiographic cure results: 14 in 20 cases which embolized with ONYX-18; only 1 in 6 cases with Glubran-2. Three in 10 cases of thoracic SDAVF and 12 in 16 cases of lumbar/sacral SDAVF were cured with embolization. Partially embolized cases were treated with surgical obliteration of drainage veins within 2 weeks. Cured patients experienced immediate improvement after embolization and kept getting better in the follow-up. All the patients had MRI follow-up after 3 months and DSA follow-up after 6 months. In 6 month's follow-up, MRI showed the edema and flow void signal in the spinal cord disappeared. DSA showed no fistula recurrence or remnant. There was no deterioration case in all of the embolized cases.</p><p><b>CONCLUSIONS</b>Particular SDAVF is suitable for embolization with ONYX-18. Most lesions located in lumbar and sacral segment are good indications for embolization.</p>

RESUMEN
<p><b>OBJECTIVE</b>To analyze the prevalence of asthma and asthma related symptoms among children aged 0-14 years in three Chinese cities and to obtain a crude estimation of the trend of childhood asthma prevalence in China.</p><p><b>METHODS</b>A cross-sectional, population-based survey of prevalence of asthma was conducted in children aged from 0 to 14 years in 3 major cities of China (Beijing, Chongqing, and Guangzhou) with different geographic locations. All the subjects were randomly selected by a multi-stage sampling method. Three to five schools and kindergartens in 2 urban districts in each city were randomly selected for the survey, and a validated questionnaire that included the core questions of the International Study of Asthma and Allergies in Childhood, Phase III questionnaire and several additional questions were used. All questionnaires were completed by parents or guardians of the selected children. Children whose parents responded affirmatively to the question "Has your child ever been diagnosed as asthma by a doctor" were recognized as victims of asthma.</p><p><b>RESULTS</b>The prevalence of asthma in Beijing, Chongqing, and Guangzhou was 3.15%, 7.45%, and 2.09%, respectively. These values were significantly higher than those obtained 10 years ago in the national epidemiological survey in 2000 which used the same method of investigation and the same diagnotic criteria (χ²=3.938, P=0.047; χ²=73.506, P≤0.001; χ²=11.956, P=0.001, in each city). Of the asthmatic children 57.21%, 69.91%, and 60.00% had their first attack before the age of 3 in Beijing, Chongqing, and Guangzhou, respectively. Wheezing was the primary clinical manifestation for all asthmatic children, followed by persistent cough and repeated respiratory infections. Both the prevalence of asthma and asthma-related symptoms were statistically higher in males than in females.</p><p><b>CONCLUSION</b>The prevalence of childhood asthma is statistically higher than that 10 years ago in the three Chinese cities.</p>

Based on the integration of concept and methods of cause-eliminated life expectancy (CELE), health-adjusted life expectancy (HALE) and disability-adjusted life year (DALY), a new index named cause-excluded health adjusted life expectancy (CEHALE) was developed in this study to evaluate the health impact(both fetal and non-fetal) of single disease. In order to include the impact of both premature death and health problems among those who are alive, the concept of suppositional death was introduced to calculate CEHALE. Cause-excluded health adjusted life expectancy developed in this study, should be not only easy to understand in concept, but also has theoretical support and be not affected by age structure, and be more suitable to use in comparison among different diseases and different population. Moreover, the new index is easy to calculate. So, CEHALE should be an ideal index to evaluate the impact of disease to population health.
