Objective To explore the postoperative recovery of the patients with glioma-related epilepsy and the possible risk factors for recurrence of epilepsy.Methods To collect clinical data of 89 patients with glioma-related epilepsy,we recorded Engle grade score of all patients underwent resection of tumor and seizure focus in a week,1,3 and 6 month after surgery Repeated measures ANOVA was used to analysis the difference within group.Kaplan-Meier method and Cox regression analysis were used to analysis seizure recurrence risk curve and the epileptic recurrence related factors,respectively.Results The postoperative recurrence rate was 26.97％ (24/89).Engle grade scores were 2.966±0.081.2.202±0.080,1.730±0.093 and 1.313±0.042 in a week,1,3 and 6 month after surgery.The difference was statistically significant (Ftime=96.076,P=0.000).Cox regression model showed that tumor accumulation site (RR =2.908,CI:1.083 ～7.806),postoperative edema formation (RR =4.769,CI:1.737 ～ 13.096),tumor relapse (RR=8.309,CI:3.379～20.432)were the important risk factors for recurrence epileptic seizures (all P＜ 0.05).Conclusions Surgical treatment can significantly reduce or even eliminate seizures postoperative and its long term efficacy is superior to short term efficacy.Appropriate measures should be taken to treat risk factors associated with recurrence epileptiform seizure to improve the prognosis of patients quality of life.

Objective To summarize the experience of nursing cancer patients with Wernicke encephalopathy (WE) after gastrointestinal surgery. Method The clinical data of 6 patients with WE after gastrointestinal surgery in our hospital from January 2005 to June 2015 were retrospectively analyzed to summarize the nursing strategies. Results All the 6 patients showed mental changes of different types, 5 patients developed with ocular manifestations and one patient with ataxia. Only one patient showed the classic triad of the disease at clinical presentation. All the 6 patients had characteristic manifestations on cranial MRI and received thiamine (vitamin B1) at diagnosis. Four patients were completely recovered and 2 were partially recovered. Conclusion Timely sufficient thiamine supplementation during the perioperative period is the key to prevent and treat WE in the patients with gastrointestinal cancer. Careful observation of the patients′ mental state and the effective nursing for the special classic triad of the disease are critical for a better prognosis.

Objective To explore the down-regulation of advanced receptor for advanced glycation end products(RAGE)on expression of high mobility group protein B1(HMGB1)in glioma cells line and the volume change of transplanted tumor in nude mice. Methods HMGB1 expression in glioma LN229 cells line (divided into a control group and a study group) was observed by immunohistochemical assay and Western blot. The control group received normal saline,whereas the study group received RAGE receptor blocking agent FPS-ZM1. Expression of HMGB1 protein was detected by the same methods. The difference of the expression was examined by independent sample t test. 30 Nu/Nu nude mice were randomly divided into two groups;the above two kinds cell lines were injected into the same area of the left back of nude mice. Six weeks after injection ,the volume size was measured six times ,and the variance of repeated measurement data was used to analyze the difference of the volume change. Results HMGB1 protein was mainly expressed in the cytoplasm and nucleus. As compared with the control group,HMGB1 protein expression levels were decreased in the study group(P < 0.05),the growth rate of transplanted tumor in nude mice was significantly faster in the control group than in the study group ,the difference was statistically significant(P < 0.05). Conclusions The growth and invasion of HMGB1 protein may be involved in glioma by RAGE receptor. RAGE receptor blocker FPS-ZM1 can significantly reduce the expression of HMGB1 protein and inhibit the growth of transplanted tumor volume. It is expected to be used for the research on glioma cell apoptosis.

Objective To explore the expression of human sodium coupled neutral amino acid transporter 1 (SNAT1) in human glioma tissues and its relationship with clinical pathological parameters and prognosis. Methods Immu?nohistochemical and western blotting were used to detect SNAT1 expression in glioma tissue and tumor peripheral tissue from 89 cases of glioma patients including 55 cases of low grade gliomas (WHO I-II), and 34 cases of high grade gliomas (WHO grade III-IV).χ2 test and was used to analyze the relationship between expression and clinical pathological param?eters of SNAT1. Kaplan-Meier method was used to analyze the effect of different expression of SNAT1 on the prognosis of patients and to establish the Cox regression model. Results The expression of SNAT1 was significantly higher in gliomas than in tumor peripheral tissue (t=-9.803, P=0.001). The expression of SNAT1 was significantly higher in high pathologi?cal grade tissues than in low grade of glioma tissues (t=-6.682, P=0.003). SNAT1 expression was associated with tumor di?ameter and pathological grade (χ2=4.963, 8.527, P<0.05);Cox regression model showed that the tumor pathological grade and different SNAT1 protein expression were independent risk factors for the prognosis of patients with glioma. Conclu?sions The expression of SNAT1 protein is closely associated with the pathological grade of gliomas and the prognosis of the patients, which may be a new target to judge the biological characteristics and to evaluate the prognosis of gliomas.

Objective To explore expression of HMGB1 and TLR4 in epileptogenic focus brain tissue of temporal lobe intractable epilepsy patients, and analyze its significance in epileptic seizures. Methods 85 tempo-ral lobe intractable epilepsy patients were included in the research. Patients underwent resection of epileptogenic focus in Neurosurgery Department of The Fifth Affiliated Hospital of Zhengzhou University during January 2011 to January 2012. Epileptogenic focus brain tissue during operation were studied. 20 patients underwent intracranial decompression were selected as control group. Normal brain tissue during operation were studied. Immunohisto-chemical method was applied to detect HMGB1 and TLR4 expression level in epileptogenic focus brain tissue of ex-perimental group patients and normal brain tissue of control group patients. Correlation of HMGB1 and TLR4 expres-sion level and epileptic seizures was analyzed. Results Positive expression rate of HMGB1 (χ2= 74.375, P =0.000) and TLR4(χ2= 57.495, P = 0.000) in epileptogenic focus brain tissue of experimental group patients are both higher than that in normal brain tissue of control group patients. Expression of HMGB1 and TLR4 in epilepto-genic focus brain tissue is correlated with course of epilepsy (χ2= 25.798, P = 0.000), (χ2= 10.548, P = 0.001) preoperative epileptic seizure duration(χ2=8.403, P=0.004),(χ2=10.564, P= 0.001) and preoperative epilep-tic seizure frequency (χ2=4.912, P=0.027), (χ2=5.567, P=0.018). Conclusions HMGB1-TLR4 passageway may become new direction to study pathogenesis, diagnosis, and treatment of intractable epilepsy.

From August 2011 to March 2012,5 241 type 2 diabetic patients with body mass index ≥ 24kg/m2 were enrolled from 60 hospitals in Guangdong Province.According to estimated glomerular filtration rate (eGFR),a total of 2 631 subjects with norml urine microalbumin level (＜30 ng/L) were divided into normal eGRF group and decreased eGRF group.Binary logistic regression was used to analyze the associations between eGFR and its related risk factors.The results showed that age,blood uric acid,blood urea nitrogen,history of hypertension and coronary heart disease,family history of diabetes,and hyperuricemia were positively related to lowering of eGFR (P＜ 0.05 or P＜0.01).HbA1C＜7％,regular glucose monitoring,and regular physical activity were negatively related to eGFR decrease (all P＜ 0.01).These results suggest that urine microalbumin and eGFR should be applied to overweight or obese patients with type 2 diabetes in order to screen diabetic nephropathy.Furthermore,intensive control of blood glucose,uric acid,and blood pressure is beneficial to lowering the risk of diabetic nephropathy.
