In30 cases, Epileptic seizures were usually the Initialand main symptoms, but local neurological signswere usually absent. All of the cases were treatedby antibiotic therapy. The duration of the therapyin most childhood patients was 2～3 months exceptthree who were over 3 months.

Objective To analyze the relationship between diabetics and the onset, clinical outcomes and prognosis of brainstem infarction, and to evaluate the impact of diabetes on brainstem infarction. Method Compare 172 cases of acute brainstem infarction in patients with or without diabetes.Analyze the associated risk factors of patients with brain-stem infarction in diabetics by multi-variate logistic regression analysis. Compare the National Institutes of Health Stroke Scale (NIHSS) and Modified Rankin scale (mRS) Score, pathogenetic condition and the outcome of the two groups in different times. Results The systolic blood pressure ( SBP ), TG, LDL-C, apolipoprotein B ( Apo B ), glutamyl transpeptidase (γ-GT), fibrinogen(Fb), fasting blood glucose (FPG) and glycosylated hemoglobin( HbA1c)in diabetic group were higher than those in non-diabetic group , which was statistically significant ( P ＜ 0. 05 ). From multi-variate logistic regression analysis, γ-GT, Apo B and FPG were the risk predictors of diabetes with brainstem infarction( OR = 1. 017, 4. 667 and 3. 173, respectively), while HDL-C was protective( OR =0. 288). HbA1c was a risk predictor of severity for acute brainstem infarction( OR = 1. 299), while Apo A was beneficial( OR =0. 212). Compared with brain-stem infarction in non-diabetic group, NIHSS score and intensive care therapy of diabetic groups on the admission had no statistically significance, while the NIHSS score on discharge and the outcome at 6 months' of follow-up were statistically significant. Conclusions Diabetes is closely associated with brainstem infarction. Brainstem infarction with diabetes cause more rapid progression, poorer prognosis, higher rates of mortality as well as disability and higher recurrence rate of cerebral infarction.

Objective To evaluate the efficacy between cylindrical abdominoperineal resection(CAPR)by laparoscopy and traditional abdominoperineal resection(APR). Methods A retrospectively analysis was done in the data of patients with low rectal cancer who underwent APR in our department from January 2010 to September 2015. The patients were divided into two groups,including cylindrical abdominoperineal resection by laparoscopy and traditional abdominoperineal resection. The operation time,intraoperative bleeding,the time of intestinal exhaust as well as the postoperative complications of the two groups were compared. Results There were no statistical differences in the intraoperative bleeding,operation time,the time of intestinal exhaust,postoperative intestinal obstruction and pulmonary infection between the two groups(P > 0.05). However,the differences in the rates of perineal incision infection and tumor intestinal perforation between the two groups were statistically significant (P < 0.05). Conclusion CAPR by laparoscopy is safer,more reliable than traditional APR,which can effectively reduce the rates of postoperative incision infection and tumor intestinal perforation of patients.

Objective To investigate the correlation between diabetes and brainstem infarction. Methods The diagnozed patients with acute cerebral infarction were recruited in the study. Firstly, they were divided into brainstem infarction group and non-brainstem infarction group, and then they were redivided into brainstem infarction with diabetes, brainstem infarction without diabetes, non-brainstem infarction with diabetes and non-brainstem infarction without diabetes groups according to whether they had diabetes or not. Carotid artery intima-media thickness (IMT) and carotid atherosclerosis were detected and identified with Doppler ultrasound; brain stem infarction and its location were identified with diffusion-weighted imaging; basilar artery atherosclerosis was detected with magnetic resonance angiography (MRA). A multivariate logistic regression analysis was used to screen the different risk factors impacting brainstem infarction. Neurological deficit was evaluated with the modified Rankin Scale (mRS)scores. Results A total of 286 patients with acute cerebral infarction were recruited: brain stem infarction in 63, and 34 of them with diabetes; non-brain stem infarction in 223, and 77 of them with diabetes. The proportions of diabetes (54. 0％ vs. 34. 5%, x2 = 7. 816, P = 0. 005),previous cerebral infarction (38. 1％ vs. 24. 2％ ,x2 =4. 771, P =0. 029), basilar artery atherosclerosis (73.0％ vs. 57. 4％,x2 =5. 028, P =0. 025), as wall as the levels of hemoglobin A1C (HbA1c) (7. 30 ± 2. 42％ vs. 6. 46 ± 1.82％, t = - 2. 531, P = 0. 011 ) and apolipoprotein B (ApoB) (0. 97 ± 0. 33 mmol/L vs. 0. 90 ± 0. 34 mmol/L, t =-2. 180, P = 0. 029) in the brainstem infarction group were significantly higher than those in the non-brainstem infarction group. Multivariate logistic regression analysis showed that diabetes (odds ratio [ OR] 2. 150, 95％confidence interval [ CI] 1. 214-3. 808; P =0. 009) and previous cerebral infarction (OR 1. 835, 95％ CI 1.004-3. 352, P = 0. 048) were the independent risk factors for brainstem infarction. There were significant differences in the levels of HbA1c (P ＜ 0. 001 ), fasting blood glucose (FBG) (P ＜0. 001), ApoB (P =0. 007) and high-density lipoprotein cholesterol (P =0. 018) as well as the proportion of basilar artery atherosclerosis (P = 0. 001 ) among the brainstem infarction with diabetes, without diabetes, non-brainstem infarction with diabetes and without diabetes groups. The levels of HbA1c (8. 81 ±2. 36％), FBG (8. 23 ±3. 12 mmol/L andApoB (1.04 ± 0. 41 mmol/L) as well as the proportion of basilar artery atherosclerosis (85. 3％ )were the highest in the brainstem infarction with diabetes group. Conclusions Diabetes is closely associated with brainstem infarction. Diabetes is more likely to result in pontine infarction.

Objective To investigate the features of risk factors of minor stroke with CISS classification in Guangdong Province. Methods We retrospectively investigated the patients admitted within 3 days of the occurrence of a minor stroke, and were classified by CISS criteria as large artery atherosclerosis (LAA), cardiogenic stroke (CS), penetrating artery disease (PAD), other etiology (OE), undetermined etiology (UE). Results In this study, 303 pa-tients met the inclusion criteria of minor stroke. The highest percentage of the risk factors included hypertension (72.3%), hyperlipidemia (58.3%), and diabetes mellitus (39.9%). Among different subtypes, 41.9% were diagnosed with LAA, and 50.8% with PAD. Plasma triglyceride (TG)(1.765 ±1.18)mg/L vs.(2.19 ±1.84)mg/L,P=0.03], apolipoproteinsB (ApoB) [(0.95±0.29)mg/L vs.(1.11±0.46)mg/L,P=0.009]C-reactive protein (CRP) [(6.63±11.30) mg/L vs.(3.42 ±5.02)mg/L,P=0.042] and ApoB/ApoA1 ratio [(0.754 ±0.25)mg/L vs.(0.875 ±0.49)mg/L,P=0.019], differed significantly between group LAA and PAD. Conclusion Hypertension, hyperlipidemia and diabetes mellitus are the major risk factors of minor stroke. The most common subtypes of the minor stroke patients in Guangdong Province are LAA and PAD, and detecting their TG, apoB, CRP level and apoB/apoA1 ratio might help subclassify minor stroke according to CISS.

Objective To compare the efficiency of original neuromyelitis optica(NMO)-IgG assay of detecting NMO-IgG with a new anti-aquaporin-4(AQP4)assay of detecting AQP4,and to explore the accuracy of the method in the diagnosis of NMO and multiple sclerosis(MS).Methods The sera were obtained from 44 patients with NMO and 46 patients with MS and were tested by both NMO-IgG and antiAOP4 assays.NMO-IgG was identified by original NMO-IgG assay with a substrate from mouse brain.AntiAQIP4 was detected by anti-AQP4 antibody assay.The results from the two assays were statistically analyzed to compare accuracy and specificity of the methods.Results The results of the two assays were concordant in 45 testing negative cases and 36 positive cases(Kappa=0.798.P=0.000).The McNemar test showed that the positive rate of the two assays were not significantly different(P=1.000).The NMO-IgG assay showed 77.3% sensitivity,87% specificity,82.2% diagnosis accuracy,85%positive predictive value,87% negative predictive value.and 74.3%Younden index. The anti-AOP4 antibody assay showed 88.6% sensitivity,95.7%specificity,92.2% diagnosis accuracy,98.1% positive predictive value,89.8% negative predictive value.and 84.3% Younden index.Conclusions This study demonstrated that NMO-IgG and AQP4 antibody detection have high sensitivity and specificity to detect NMO and MS.Anti-AQP4 detected by anti-AQP4 antibody assay may be more useful for NMO diagnosis.
