Objective To investigate the effects and significance of neuronavigation and electrocorticography monitoring in resection of eloquent brain glioma. Methods Thirty-six cases with intracranial tumors accepted microneurosurgery resection under neuronavigation and electrocorticography monitoring. The clinical data and postoperative outcome were analyzed. Results The mean registration error was (2.0 ±0. 5)mm in all operations and all skin flaps and bone windows designed by neuronavigation could fit the operation demands. Total resectin of the tumor was achieved in 31 cases and subtotal resection in 5 cases. Neurological symptoms improved and no severe complications or death happened in all patients. Conclusion Neuronavigation combined with electrocorticography monitoring can accurately locate the eloquent glioma and retrieve the brain shift. This method is a real-time technique and has functional test ability. It can improve the total removal rate and decrease the mortality and disabled rate.

Objective To improve the preoperative diagnosis accuracy of cerebellopontine angle tumors through analyzing MRI findings. Methods Ninety-six cases with cerebellopontine angle tumors, confirmed by pathology and surgery, were collected and underwent MRI scan plus enhanced MRI. Among the 96 capes, we observed acoustic neurinoma in 55 cases, meningioma in 20 cases, cholesteatoma in 9 cases, trigeminal neuroma in 7 cases,cavernous hemangioma in 3 cases,arachnoid cyst in 2 cases. The MRI characteristics of all cases were analyzed retrospectively. Results The chief type of tumor happened in the cerebellopontine angle zone was acoustic neurinoma,followed in order by meningioma,cholesteatoma,trigeminal neuroma,cavernous hemangioma and arachnoid cyst. The accuracy of preoperative localization and qualitative diagnosis were 100% and 94.7%respectively.Conclusion MRI has a high value in the diagnosis and differential diagnosis of cerebellopontine angle tumors,which can be used as a preferred preoperative examination method in cerebellopontine angle tumors.

Congenital disorders of glycosylation(CDG)are caused by defects in the synthesis of glycans and their binding to proteins and lipids.Up to now, over 100 types of CDG have been identified.This disease can cause functional damage to multiple organs including liver, kidney and heart.The CDG types with predominant or isolated liver involvement including MPI-CDG, TMEM199-CDG, CCDC115-CDG, and ATP6AP1-CDG.Their clinical manifestations include enlarged liver, elevated transaminase, cholestasis, liver fibrosis, liver failure, abnormal ceruloplasmin, and copper accumulation.Their pathological manifestations include steatosis, fibrosis, liver cirrhosis, cholestasis, and abnormal bile duct.This review mainly describes the types of CDG and their pathogenesis, clinical manifestations and liver involvement to provide a perspective for the diagnosis of CDG with liver manifestations.

Objective To understand the current status,type,and effect of training programs conducted by Health Bureau and CDC in China.Methods One person of each province was selected from China field epidemiology training network and designated as contact person who was responsible for collecting information of field practical training lasting for at least 6 months for staff of public health emergency and infectious disease control in each province from October 2001 to October 2010.Questionnaire including basic condition,organization and management,training design,faculty condition,trainee condition and training outputs was designed and filled in by contact person.Results There were 35 training programs covering over 9 provinces in China.The first province and city FETP started in 2004,including Guangdong FETP,Zhejiang FETP,Hangzhou FETP,Ningbo FETP and Guizhou FETP.Thirty-five training programs had 355 mentors,22(6％)were CFETP graduates and 57 (16％)were local FETP graduates.All program funds were paid by local governments.The training programs included two parts,theoretical lectures and field practice,which occupying 10％-20％ and 80％-90％ of the whole training time,respectively.Among 6 evaluative items including emergency investigation,surveillance analysis,surveillance evaluation,planned investigation,investigation report and paper publication,most programs(50％-94％) had less than average one person per time.Conclusions Field epidemiology training program after several years of development in china achieves the certain scale.Some provincial programs are successful,but the effect and quality of training programs in different areas are uneven.We suggest optimizing of field epidemiology training resources and further expanding China field epidemiology training network.

OBJECTIVE: To analyze the clinical effect of different canalith repositioning maneuver in the treatment of the apogeotropic nystagmus of horizontal semicircular canal benign paroxysmal positional vertigo (apogeotropic HSC-BPPV). METHOD: Forty patients of apogeotropic HSC-BPPV colleted from March 2014 to May 2015 were divided into two groups, each group had 20 cases. The control group was repositioned with the Gufoni maneuver before the Barbecue maneuver, the research group with the improved Nuti maneuver. RESULT: The success rate of the research group was not lower than that of the control group, which hadn't statistical (P > 0.05). And after the Barbecue maneuver, all patients have been recovered. CONCLUSION Comparing with the Gufoni maneuver, the improved Nuti maneuver designed by us, had the same success rate to treat apogeotropic HSC-BPPV, and is easier to learn,with more compliance,more comfort and more repeatability.

Objective To evaluate the effect of nodosin,as an effective element extracted from rabdosiae serrae, on hepatocyte regeneration after partial liver transplantation.Methods Wistar rats were used as donors and SD rats as recipients.Rat models with partial liver transplantation were established by modified two-cuff technique.Twenty-four recipient rats were randomly assigned into the nodosin and control groups.In the nodosin group,nodosin at a dosage of 1 00 μg/ml was administered via tail venous route after liver transplantation.Peripheral plasma and liver specimen were obtained at postoperative 3 and 7 d.The levels of alanine transaminase (ALT),aspartate aminotransferase (ALT)and albumin (ALB)in the peripheral plasma were measured by spectrophotometry.Hepatic histomorphological changes were observed under light microscope.The positive cell count of proliferating cell nuclear antigen (PCNA)antibody in the liver tissue was detected by immunohistochemistry. The expression levels of phosphorylated protein kinase (p-AKT ), phosphorylated mammalian target of rapamycin (p-mTOR),cyclin D1 and heme oxygenase (HO)-1 proteins were measured by western blot.The apoptosis of liver cells was detected by Annexin V method and TdT mediated-dUTP nick end labeling (TUNEL).Results Compared with the control group,the serum levels of ALT and AST were significantly lower at 3 d and 7 d after operation,whereas the ALB content was significantly higher in the nodosin group (all in P <0.05).And nodosin could alleviate the pathological injury of rat liver tissue after transplantation.The positive cell count of PCNA in the nodosin group was significantly higher than that in the control group (P <0.05).In the nodosin group,the expression levels of p-AKT,p-mTOR,cyclin D1 and HO-1 proteins were significantly higher than those in the control group (all in P <0.05).The quantity and percentage of apoptotic hepatocytes in the nodosin group were significantly lower than those in the control group (both in P <0.05).Conclusions Application of nodosin can decrease the quantity of apoptotic hepatocytes and accelerate hepatocyte proliferation after liver transplantation in rat models.
