Objective To determine the relationship between polymorphism of apolipoprotein E gene (APOE) and electroencephlogram in patients with mild/moderate traumatic brain injury. Methods (1) Venous blood for 2 ml was collected from 81 patients with mild/moderate traumatic brain injury on admission. APOE genotype was identified by PCR restriction fragment length polymorphism ( PCRRFLP). (2) All the patients were monitored by electroencephalogram for 2-3 times within a week after injury. X2 test and logistic regression analysis via SAS version 8.2 were performed to analyze the results of genotype and electroencephalogram and clinical data. Results The distributions of genetypes and alleles among 81 patients matched with Haldy-Weinberg Law. The findings of electroencephalogram were significantly different between patients with and without APOEε4 (P<0.05). Ten (63%) out of 16 patients with APOEε4 showed an aggravated electroencephalogram,while only 16 (25%) out of 65 patients without APOEε4 showed the same results of electroencephalogram. Logistic regression analyses showed that APOEε4 was a risk factor for electroencephalogram aggravation after traumatic brain injury. Conclusion APOEε4 is a risk factor for electroencephalogram aggravation during acute stage after mild/moderate traumatic brain injury.

Objective To investigate the influence of apolipoprotein E gene (APOE) polymorphism on the acute-phase brain electrical activity after mild/moderate traumatic brain injury. Methods The clinical data of 112 patients with mild/moderate traumatic brain injury were collected and the APOE genotypes were identified by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The brain electrical activity in every patient was recorded twice by using electroencephalogram within one week after injury. Qualitative and quantitative methods were used to determine the variations of brain electrical activity. Chi-square test, variance analysis and logistic regression analyses via SPSS version 11.5 were performed among APOE genotypes, electroencephalogram data and clinical data. Results The distributions of APOE genetypes and alleles matched Haldy-Weinberg Law in 112 patients. Of 22 patients with APOEε4, 12 patients (55%) presented with deteriorated electroencephalogram, which was significantly higher than those (16 of 90 patients, 18%) without APOEε4 (P ＜ 0. 01). Comparison of the first and second electroencephalograms demonstrated that the slow waves were increased significantly in patients with APOEε4 ( P ＜ 0. 01 ) but decreased in patients with APOEε2 and APOEε3 (P ＜0.05). The reduction of slow waves in APOEε2 carriers was more obvious than APOEε3 carriers (P ＜0.05). Univariate and multivariate logistic regression analyses showed that APOEε4 was a risk factor to electroencephalogram aggravation after traumatic brain injury. Conclusion APOEε4 is a risk factor to electroencephalogram aggravation during acute stage after mild/moderate traumatic brain injury. However,APOEε2 seems to be beneficial for recovery of brain electrical activity.

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.

Objective:To determine the difference of curative effects of gamma knife treatment and microsurgery on patients with recurrent trigeminal neuralgia (TN) after microvascular decompression (MVD).Methods:From January 2011 to December 2018, 65 patients with recurrent TN after MVD were enrolled in the study; 40 patients received gamma knife treatment and 25 patients received secondary microsurgical treatment. Barrow Neurological Institute (BNI) proposed pain grading was used to evaluate the efficacies right after treatment and 3 years after follow-up in all patients, and grading I-III was defined as pain relief.Results:Patients received gamma knife treatment had pain relief within 4-10 weeks of treatment and disappeared gradually; patients received secondary microsurgical treatment had disappeared facial pain immediately after waking up from anesthesia or completely alleviated facial pain within one week of treatment. Up to 3 years after surgery, follow-up results showed that 17 patients (68.0%) in the gamma knife treatment group had pain relief, and 16 patients (94.1%) in the microsurgical treatment group had pain relief; the difference in pain relief rate between the two groups was statistically significant ( χ2=4.100, P=0.043). Facial numbness was noted in the gamma knife treatment group, with an incidence of 24.0%; in the microsurgical treatment group, hemiplegia was noted in one patient and facial numbness was noted in the left ones, with complication rate of 29.4%; and the difference in complication rate between the two groups was not statistically significant ( χ2=0.010, P=0.921). Conclusion:For patients with recurrent TN after MVD, secondary microsurgical treatment and gamma knife treatment are safe and effective, among which secondary microsurgical treatment is more effective than gamma knife treatment.

【Objective】 To investigate the preparation quality and clinical application effect of pooled platelets with leukocytes reduced. 【Methods】 The quality and clinical effect of the buffy-coated method prepared pooled platelets leukocytes reduced (experimental group, n=40) and apheresis platelets leukocytes reduced (control group, n=40) were compared. 【Results】 The platelet volume (mL), platelet count (×10¹¹), red blood cell contamination (×10⁸) and residual white blood cell (×10⁶) of the experimental group and control group were 278.90±7.92 vs 276.52±8.01, 2.66±0.09 vs 2.66±0.83, 0.54±0.42 vs 0.83±0.84, 0.29±0.54 vs 0.27±0.51, respectively, with no significant difference. The results of bacterial culture were negative, all met the requirements of relevant national standards. In addition, the CCI (×10^3, 24 h) and PPR (%) were 15.11±9.86 vs 14.61±12.55 and 54.23±18.70 vs 61.41±19.09 respectively, with no significant difference, indicating a certain degree of therapeutic effect. 【Conclusion】 The quality and clinical therapeutic effect of pooled platelets leukocytes reduced were consistent with that of apheresis platelets leukocytes reduced.
