Objective To explore the effect of microsurgery for refractory temporal lobe epilepsy . Methods A retrospective analysis was made in 102 patients with refractory temporal lobe epilepsy from January 2005 to December 2011.The patients received comprehensive preoperative localization , intraoperative frontotemporal pterional incision , and microsurgical resection of epileptogenic focus .The efficacy was evaluated according to the Engel standards .Indications such as self-care ability, learning ability, and working ability were used to evaluate the quality of life , which were recorded and compared before and after operation . Results Follow-up was accomplished in all the 102 cases for a duration of 1 year and 9 months to 7 years.There were no mortality and serious complications .The effects evaluations at 1 year after operation showed complete disappearance of symptoms ( levelⅠ) in 61 cases (59.8%), almost disappearance (level Ⅱ) in 17 cases (16.7%), symptoms improvement more than 75% (level Ⅲ) in 13 cases (12.7%),and ineffective (level Ⅳ) in 11 cases (10.8%), bearing an effective rate of 89.2% (91/102) and a good-and-excellent rate of 76.5%(78/102).At one year and nine months postoperatively , 6 patients could not take care of themselves , 32 patients obtained partial self-care, and 64 patients had complete self-care,as compared with which there were 21 patients, 67 patients, and 14 patients preoperatively, respectively, having significant differences before and after surgery (Z =-7.001, P =0.000). Statistical significances were obtained before and after operation in 67 cases of children and adolescents with learning ability ( Z=-3.747, P =0.000) and in 35 adult cases with working ability ( Z =-2.564, P =0.010). Conclusions Microsurgical treatment is an effective method for refractory temporal lobe epilepsy .Patients ’ quality of life can get significant improvement after surgery.

Aim To establish an ideal hyperlipidemia animal model by a new way.Methods 30 mice were randomly divided into control group, positive control group and model group.The mice of control group were only fed with a standard diet.Those of positive control group were fed with high fat diet.Those of model group were fed with a standard diet and enough milk.After 30 days the TG, TC, HDL-C and LDL-C of serum and hepatic and LI were detected and pathological changes in the liver of mice were observed microscopically.Results Compared with the control group, the mice of model group developed hyperlipidemia with LI and the serum and the hepatic TG, TC, LDL-C elevated significantly, while HDL-C were significantly lower.The histopathological research showed hepatocellular macrovesicular steatosis and hepatitis in the model group.Conclusion An ideal model of hyperlipidemia is successfully established with standard diet and milk fed to mice for 30 days.

BACKGROUND:An amyloid-beta (Aβ) aggregation in the brain can induce nerve cel apoptosis, loss of synapses and functional damage. However, there is stil no effective intervention. Improving the synaptic plasticity provides an important direction for the treatment of early Alzheimer’s disease. OBJECTIVE: To screen the best model of Alzheimer’s disease and to explore the expression of synapse-associated proteins in Aβ25-35-injured PC12 neurons. METHODS:PC12 cels were induced by 50 μg/L nerve growth factor to differentiate into neuronal-like cels. Then, these cels were treated with Aβ25-35 at different concentrations. Consequently, cel survival rate was detected using cel counting kit-8; neurogranin and neuregulin immunofluorescence stainings were used to observe morphological changes of model cels; western blot used to detect the expression level of neurogranin, calmodulin kinase II, postsynaptic density-95 proteins. RESULTS AND CONCLUSION:Over time, the survival rate of PC12 neurons induced by Aβ25-35 was decreased in a dose-dependent manner. Shortened synaptic length, neuronal atrophy and sparsely interconnected neurons were visible. Expression levels of neurogranin, calmodulin kinase II and postsynaptic density-95 proteins were al down-regulated. These findings indicate that to screen the cel model of Alzheimer’s disease, the optimal concentration and interventional time of Aβ25-35are 10 μmol/L and 48 hours, respectively.

Objective To investigate the clinical effects of subemergency treatment of femoral intertrochanteric fractures in elderly patients.Methods From June 2013 through February 2014,47 patients older than 65 years were treated for femoral intertrochanteric fracture at our department and completed full follow-ups.Of them,20 received subemergency operation.They were 9 men and 11 women,with an average age of 72.2 ± 4.8 years.By the Evans-Jensen classification,there were 2 cases of type Ⅰ,5 of type Ⅱ,5 of type Ⅲ,5 of type Ⅳ,and 3 of type Ⅴ.The time from injury to surgery ranged from 0.5 to 1.7 days (average,0.8 days).The other 27 patients underwent selective operation.They were 11 men and 16 women,with an average age of 74.9 ± 5.7 years.By the Evans-Jensen classification,there were 3 cases of type Ⅰ,6 of type Ⅱ,6 of type Ⅲ,7 of type Ⅳ,and 5 of type Ⅴ.The time from injury to surgery ranged from 2 to 5 days (average,3.4 days).We compared the 2 groups in terms of in-hospital complications,fracture healing time,length of hospital stay,and hip scores at the last follow-up.Results All the patients were followed up for 12 to 15 months (mean,13.4 months).The rate of in-hospital complications in the subemergency operation group (35.0％,7/20) was significantly lower than that in the selective operation group (51.9％,14/27),and the length of hospital stay in the former (12.1 ± 1.6 days) was significantly shorter than in the latter (16.1 ± 1.8 days) (P ＜ 0.05).There was no significant difference between the 2 groups in fracture healing time (13.1 ± 1.8 weeks versus 13.6 ± 1.2 weeks) (P ＞ 0.05).According to the hip scores at the last follow-up,the subemergency operation group had 16 excellent,2 good,one fair and one poor cases (with an excellent to good rate of 90.0％) while the selective operation group had 21 excellent,2 good,2 fair and 2 poor cases (with an excellent to good rate of 85.2％),showing no significant difference between groups (P ＞ 0.05).Conclusion Subemergency operation can reduce not only in-hospital complications but also length of hospital stay for old patients with femoral intertrochanteric fracture.

[ABSTRACT]OBJECTIVETo improve the understanding and treatment of otogenic deep neck abscess.METHODSTo analyse the treatments of 2 cases retrospectively and do the literature review.RESULTS 2 cases had long history of otitis media, showed abnormal signal connection on MRI image between neck lesion and middle ear. They were cured by mastoidectomy and drainage from neck abscess to mastoid cavity.CONCLUSIONThe otogenic deep neck abscess is different from other one in the etiology, pathogenesis, pathogenic bacteria, treatment and so on. The neck MRI examination has obvious advantages in the nature of the lesion, the resolution of the soft tissue and the correlation of lesions between the neck and the mastoid, and can be used as the predominant treatment. Incision and drainage of the neck abscess is unnecessary if operated on time. Before the neck abscess is cured thoroughly, keeping drainage of the mastoid tip is very important for prevention of recurrence. Postoperative change dressing should also be strengthened.

Objective: To explore the mechanism of traditional Chinese medicine(TCM) combined with regular therapy in the treatment of pneumonia with systemic inflammatory response syndrome(SIRS) in(children).Methods: Sixty-four children with pneumonia including 51 cases with SIRS complication were(randomly) divided into three groups: treatment group(regular therapy+TCM,n=26),control group Ⅰ((regular)(therapy) only,n=25) and the control groups Ⅱ(13 pneumonia children without SIRS(receiving)(routine) treatment). The dynamic changes of tumor necrosis factor-?(TNF-?),interleukin-6(IL-6) and IL-8 were measured before and after treatment in all children.Serum Creactive protein(CRP) and total white blood cell(WBC) count were measured simultaneously.Clinical symptom and sign scores were(performed)(5 days) after treatment in children with pneumonia and SIRS complication.Results: Before(treatment),serum TNF-?,IL-6,IL-8 and CRP concentrations were significantly higher in treatment group and(control) group Ⅰ than(control) group Ⅱ(all P

Objectives:To investigate the effects of intravenous LCT or MCT/LCT fat emulsions on the lipid mediators and pancreatic histological changes in ANP rats. Methods:Forty three male SD rats were randomized to groups as follow.Group A～C were without ANP, group A:normal controls, group B:normal rats having received lipid based TPN and group C:operation control(OC) group having received the glucose fluid.Group D～F were with ANP,glucose group,Intralipid group and Lipofundin group.The amylase and prostaglandins in serum were determined in group A.Pancreatic histological examinations were also performed.In group B～F,Amylases or prostaglandins in serum were determined at 4,48 and 72 h, and pancreatic histological examination and pathological scoring were also completed. Results:Intralipid had no effects on serum prostaglandins when it was infused to normal rats.In groups of ANP,intravenous fat emulsion increased the 6 keto PGF 1? ,and PGE 2 concentration in serum at 4 h.Pancreatic hemorrhagic and fat necrosis were significantly reduced in Lipofundin group. Conclusions:Intravenous fat emulsion does not worsen the damages to pancreas in ANP.MCT/LCT fat emulsion is more suitable for patients with ANP.

The anti-aging effect of Yang Shou Dan (YSD) was studied. It was shown that YSD could obviously increase the activity of superoxicde dismutase (SOD) in erythrocyte, decrease lipid peroxides (LPO) in serum and in liver tissue and reduce the content of lipofucin in myocardium of mice. It could also prolong the mean life span, the half lethal period and the longest life time of drosophila melanogater. It is suggested that YSD exerts an anti-aging effect to a certain extent.
