Objective To explore the correlative factors of sudden death in patients suspected with pulmonary thromboembolism (PTE) in emergency room (ER).Methods A retrospective analysis was conducted.The clinical data of 12 patients with sudden death suspected with PTE (sudden death group) in ER of the Air Force General Hospital from January 2011 to June 2014 were analyzed.The non-sudden death group included 35 patients during the same time period who were diagnosed with PTE based on findings of CT pulmonary arteriography (CTPA) and showed no sudden death in ER.Factors,including sex,age,previous operation,tumor,syncope,dyspnea,bilateral or unilateral edema of lower extremity,heart rate (HR),white blood cell count (WBC),D-dimer,arterial partial pressure of oxygen (PaO2),arterial partial pressure of carbon dioxide (PaCO2) and typical clinical manifestation of electrocardiogram (SⅠTⅢQⅢ),were compared between the two groups.The potential predictors of sudden death of PTE were analyzed by logistic regression analysis.Results Young age (years old:51.3±15.5 vs.62.3±14.4),lower PaO2 [mmHg (1 mmHg =0.133 kPa):49.9± 12.3 vs.62.7± 10.2],higher HR (bpm:122.0± 19.5 vs.89.1 ± 18.5) and higher WBC (× 109/L:13.8 ± 6.9 vs.7.2 ± 2.5) were found in sudden death group as compared with those in non-sudden death group (P ＜ 0.05 or P ＜ 0.01).There was no significant differences in D-dimer level and PaCO2 between sudden death group and non-sudden death group [D-dimer (pg/L):986 (891,3 230) vs.2089 (598,3 397),PaCO2 (mmHg):33.0 (28.6,43.4)vs.36.5 (32.9,41.0),both P ＞ 0.05].The syncope,antineoplaston treatment or tumor metastasis within 6 months,operation in previous 4 months,bilateral asymmetrical edema in sudden death group were more than those of the non-sudden death group,and chest pain was less (P ＜ 0.05 or P ＜ 0.01).Difference in gender,dyspnea and typical SⅠTⅢQⅢ in electrocardiogram were not significant between the two groups (all P ＞ 0.05).It was shown by multiple logistic regression analysis that higher HR [odds ratio (OR) =1.124,95％ confidence interval (95％CI) =1.024-1.235,P =0.014] and higher WBC (OR =1.347,95％CI =1.043-1.738,P =0.022) were identified as independent risk factors of sudden death for PTE.Conclusions Gender,dyspnea,typical S Ⅰ TⅢQⅢ in electrocardiogram,PaCO2 and D-dimer seem unrelated to sudden death of patients with PTE.Young age,chest pain,syncope,bilateral asymmetrical edema,antineoplaston treatment or tumor metastasis within 6 months,operation in previous 4 months and low PaO2 were potential predictors of sudden death according to the univariate analysis.Higher WBC and higher HR are independent risk factors of sudden death for PTE patients.

OBJECTIVETo evaluate the postoperative complications of microscopic and conventional Palomo varicocelectomy in the treatment of varicocele in army personnel.

METHODSA total of 260 army personnel with varicocele were randomized to receive microscopic varicocelectomy (group A, n=130) and conventional Palomo varicocelectomy (group B, n=130). The postoperative recurrence and complications (scrotal edema, testicular pain and testicular atrophy) were compared between the two groups.

RESULTSAfter 1 year of follow-up, the recurrence rates in groups A and B were statistically comparable (5.3% vs 3.8%, P>0.05). The incidences of testicular atrophy and scrotal edema were significantly lower in group A than in group B (0.7% vs 3.1%, P<0.05; 3.1% vs 14.6%, P<0.05), and the rate of testicular pain relief was significantly higher in group A (90.7% vs 67.7%, P<0.05).

CONCLUSIONMicroscopic varicocelectomy can be a good choice in the treatment of varicocele in army personnel.

Objective To study the factors influencing prognosis in the patients with recurrent glioblastoma muhiforme (GBM) and to investigate the effect of retreatemt.Methods The retrospective analysis method was adopted to collect the clinical and follow up data in 36 cases of recurrent GBM retreatment in the neurosurgery department of this hospital from March 2008 to March 2013.The prognosis influencing factors were analyzed.Results The univariate analysis results showed that the gender,resection degree,treatment mode and initial scheme had the influence on the progression free survival(P＜0.05).The resection degree had an impact on the overall survival(P＜0.05).The multivariate analysis results showed that KPS score,resection degree and treatment mode had effect on the progression free survival(P＜0.05).The resection degree had an influence on the overall survival (P＜0.05).Conclusion If the patients with recurrent GBM still hasthe chance of operation whole excision,the re-treatment can reach the effect for relieving the symptoms,improving the quality of life and prolonging the survival period.

OBJECTIVETo analyze the polio immunity level of persistent population in Beijing, 2012.

METHODSA total of 1 676 subjects residing more than 6 months in Beijing were selected by stratified random cluster sampling design in 2012. Demographic characteristics, history of oral poliovirus vaccine (OPV) immunization were investigated by questionnaire. All 5 ml blood sample were collected for testing of polio neutralizing antibody using the method of microcell neutralization. The positive rate and the geometric mean titer (GMT) of polio neutralizing antibody type I, II and III were analyzed in different groups.

RESULTSThe positive rate of type I, II and III were 98.2% (1 645/1 676), 98.1% (1 644/1 676), 97.6% (1 635/1 676); The GMT were 1:130.2, 1: 113.4 and 1: 79.7. Three types of positive rates in<15 years group (99.7% (664/666), 99.8% (665/666), 99.5% (663/666)) were higher than those of ≥ 15 years group (97.1% (981/1 010), 96.9% (979/1 010), 96.2% (972/1 010)), the differences were significant (all the values of P < 0.01); The GMT in<15 years group (1:325.9, 1:250.5, 1:190.7) were higher than that of ≥ 15 years group (1: 71.1, 1: 67.2, 1: 44.8), the difference was significant (all the values of P < 0.01). The positive rate (99.0%-100%) and GMT (1: 128.8-1: 300.7) in vaccination information confirmed population were higher. The highest positive rate (all were 100%) and GMT(1: 409.7-1: 636.7) were observed in children who vaccinated three times.

CONCLUSIONThe polio antibody of healthy population was at a high level in Beijing in 2012; Especially the age groups of < 15 years which were covered by vaccines.Immunization barrier had been formed firmly to interrupt the transmission of wild poliovirus and vaccine-derived poliovirus.
