Objective To evaluate potential clinical risk factors for the development of early-onset myocardial damage following multiple trauma (MT), and to determine whether early-onset myocardial damage was caused by the combined effects of thoracic and systemic injury factors in MT patients.Methods A total of 231 patients with MT over the last 3 years were retrospectively reviewed. With myocardial damage being a dependent variable and other twenty factors being independent variables, univariate and multivariate logistic regressions were applied to investigate the risk factors for early-onset myocardial damage and to identify the association of thoracic and systemic risk factors with early-onset myocardial damage.Results Multivariable logistic regressions showed that acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ ) score ≥10, injury severity score (ISS) ≥ 25, shock index ≥ 2,coexisting chest trauma, abbreviated injury scale (AIS) of chest≥3, and hypoxia time ≥ 0.5 h were risk factors. The risk of earlyonset myocardial damage following MT obviously increased when thoracic and systemic injury risk factors were coexisting.Conclusion Our results indicated that thoracic injury combined with systemic injury increased the overall risk of early-onset myocardial damage following MT. Prospective validation of these findings in other clinical settings is warranted.

Objective To investigate the clinical features of VAE and to assess the predictive value of VAE cough. Methods We retrospectively reviewed the medical records of 461 consecutive patients who underwent DBS surgery at Beijing Tiantan Hospital. Patients with VAE manifestation were enrolled in this study. The clinical features, operative courses, post-operative conditions and treatment of these patients were analyzed. The correlation between intraoperative tremor intensity , cough duration and prognosis was also investigated. Results Among 461 patients,10 (2.2%) were found with evidence of VAE, including cough, dyspnea, decreased O2 saturation (SO2). Statistical analyses revealed that severe cough was associated with greater age , a longer coughing time, more intensive tremor, greater influence, and a longer length of stay (P < 0.05, rspectively). Conclusions Early recognition and prompt management of VAE are essential to prevent unfavorable consequences. Cough intensity might be a useful tool for evaluating VAE and its prognosis , which is helpful for neurosurgeons to decide on the subsequent maneuvers.

Objective: To explore the importance of mechanic al ventilation (MV) in treating multiple trauma mainly accompanied with cerebral injury and improve the treatment level. Methods: All 116 patients who suffered from multiple trauma acc ompanied with mainly cerebral injury were analyzed. Rank correlation and Chi-sq uare test were made between MV with GCS, ISS, and whether shock or not. Results: The MV was correlated with GCS, ISS scores, and whethe r shock or not markedly. Furthermore, when GCS≤8, the ratio of MV was about 70% . When ISS≥35, the ratio of MV was about 85%. Conclusions: During the treatment of multiple trauma accompanie d with cerebral injury, the principle of “early MV, early withdraw” and “indi vidualism” should be insisted on. For patients accompanied with shock, the opti mum PEEP is very important. Proper and active MV is of great importance and can improve the treatment level markedly.

OBJECTIVETo investigate the prenatal application of single nucleotide polymorphism array (SNP array) in the identification of 5p deletion syndrome with partial trisomy 11q.
METHODSG-banded karyotyping and SNP array were performed using amniocytes on a fetus with multiple malformations for the identification of chromosome abnormality. Furthermore, karyotyping was carried out on the parental peripheral blood specimens to ascertain the origin of chromosome abnormalities and then fluorescence in situ hybridization (FISH) was also utilized to confirm the results.
RESULTSKaryotype of amniocyte showed 46, XY, der(5) (?::p15 → qter). SNP array revealed a 13.907 Mb deletion at 5p15.33p15.2 (chr5: 113576-14020561), overlapping the region of 5p deletion syndrome, and a 18.254 Mb duplication at 11q23.3 q25 (chr11: 116684627-134938470), overlapping no known syndrome. Karyotype of the parents showed a normal 46,XX in mother and 46,XY,t(5;11)(p15;q23) in father. Three-color metaphase FISH analysis on paternal peripheral blood specimens also confirmed the paternal karyotyping result.
CONCLUSIONSNP array could uncover 5p deletion syndrome with partial trisomy 11q unidentified by G-banded karyotyping and accurately locate the genomic breakpoints, facilitating the mapping of pathogenic critical regions and the identification of candidate genes, also accumulating research data for genotype-phenotype study.

Objective To investigate the influences of anterior thalamic nucleus (ANT) stimulation on neurogenesis in hippocampus of epileptic rats. Methods Thirty-two male SD rats were randomly alloca-ted to normal-control group ( n=8),control-stimulation group ( n=8),sham-stimulation group ( n=8) and model-stimulation group(n=8).Eqileptic SD rat model was established by using microinjection of kainic acid in hippocampal CA3 area,and administered 48 h continuous ANT stimulation in the chronic stage.Epileptic seizures were monitored and counted.The levels of Ki-67,a neurogenesis protein in hippocampus was deter-mined by Western blot and quantitative real-time polymerase chain reaction (qRT-PCR). Results The epi-lepsy seizure rate was (5.9±2.2) per week in the sham-stimulation group and (2.9±1.1) per week in model-stimulation group.Compared with sham-stimulated rats, ANT stimulation reduced seizures by 50.8%(P<0.05).Western blot analysis revealed that the relative levels of Ki-67 in the hippocampus of model-stimula-tion group significantly higher than that of the sham-stimulation group((0.44±0.15) vs (0.19±0.73),P<0.05).qRT-PCR analysis showed that relative levels of Ki-67 mRNA in the hippocampus of model-stimula-tion group were significantly higher than that of the sham-stimulation group((0.45±0.10) vs (0.15±0.06), P<0.05). Conclusion Chronic ANT stimulation can promote neurogenesis in epileptic rats,which may be a principle mechanism of the beneficial effect of ANT stimulation on epilepsy.
