The chnical education to neurosurgical residents in different phase should be applied according to their different characters. In basic phase, basic theory and interest activation are important. In specific phase, the comprehensiveness and depth of training should be focused on. In community practice phase, the moral and scientific education should be strengthen. To trainees who have higher degree, the correct attitude and practice of knowledge should be emphasized.

Integrin-linked kinase (ILK) is a widely expressed protein kinase that relate to cellular growth and differentiation. It is most abundant in the heart. Recently, many researches revealed that ILK is highly relevant to cardiac response to biomechanical stresses. Also, ILK plays important roles in regulation of the occurrence and development of cardiac hypertrophy, dilated cardiomyopathy, viral myocarditis and myocardial senescence via correlation to several classical signal transduction pathway. Meanwhile, ILK functions in protection after myocardial infarction. This article will try to summarize the effects and relevant mechanism of ILK in above-mentioned aspects, overall reveals the roles of ILK in heart and its potential clinical significance.

Objective To investigate the therapeutic effect of mycophenolate mofetil (MMF) on rats with experimental autoimmune encephalomyelitis (EAE).Methods The guinea pig spinal cord homogenate (GPSCH) and complete Freund's adjuvant were used as the antigen to induce the acute EAE model in Wistar rats which were verified according to clinical scoring.Totally 36 rats were randomly and equally divided into 3 groups,that is,normal control,EAE group and MMF treatment group.In 10 d after immunization,normal saline or MMF (30 mg?kg-1?d-1) were given intragastrically for 7 d to the corresponding groups.The rats were sacrificed on the 16th day and 30th day after immunization for pathological changes of the brain and spinal cord.Clinical manifestation was scored during the experiment.Results Compared with the EAE model group,MMF-treated rats had lower clinical scores and shorter disease process.Besides,the inflammatory infiltration,demyelination and axonal damage in the central nervous system were significantly improved in MMF treatment group.Conclusion MMF is an effective drug in treating EAE,and can relieve the clinical signs and ameliorate pathological lesions in the central nervous system of acute EAE rats.

ABSTRACT:The seasonal characteristics of Japanese encephalitis (JE) in Gansu Province in 1962-2010 were analyzed in order to provide reference for making strategies of disease control and prevention .The JE data is the Epidemic Data between 1962 and 2003 from Gansu CDC ,and National Notifiable Diseases Registry System (NNDRS ,2004-2010) .Concentration ra‐tio and circular distribution method were used in this study .Results showed that the M‐value of the seasonal distribution of JE in 1962-2010 was 0 .825 9 .The corresponding peak date of JE was the 30th August (95% CI:22 July to 7 October) .The Z value of Rayleigh test was 3 506 .092 5 (P<0 .01) .In conclusion ,the concentration and circular distribution method helps us to grasp the JE epidemic peak season more accurately .There were significant seasona1 characteristics for JE in Gansu Province and the epidemic peak was from late July to early October .

Objective To investigate the expressions and correlation of monocarboxylate transporter-1 (MCT1) and CD147 in human gliomas,and analyzee the relationship between their expressions and prognosis.Methods Immunohistochemistry SP methods were applied to detect the expressions of MCT1 and CD147 in 28 cases of low grade gliomas and 32 cases high grade gliomas.Their expression level and correlation were analyzed statistically.Prospective cohorts were set to acquire follow-up data.Kaplan-Meier curve and Cox multi-factor model were used to analyze patients’ prognosis.Results Both CD147 and MCT1 had strong expressions in human gliomas.The positive expression rate of MCT1 and CD147 (93.8% and 90.6%) and the strong positive expression rate (73.3% and 72.4%) in high grade gliomas were significantly enhanced compared with that of low grade gliomas (positive expression rate:46.4% and 50%,strong positive expression rate:30.8% and 35.7%,P

8 patients, 6 males and 2 females, aged 26-56 years, with delayed neurologic sequelae following CO intoxication, were treated. The lucid intervals before the appearance of neurological sequelae varied from 5 days to 3 months, and the course of disease lasted for 7 days to 2.3 years. The clinical manifestations were mainly dementia, mutism, urinary or fecal incontinence, and gait disturbance. Among the 8 patients, clinical cure was obtained in 5 and improved in 3 after intrathecal oxygen administration.

Objective To explore the different methods of decoloration for immunohistochemical HE slides,and their influence on tissue antigen expression.Methods Antigen retrieval solution (EDTA or citric acid solution) was used in immunohistochemistry to decolor HE slides,and was compared with the method of hydrochloric acid solution decoloration in normal temperature.Results Antigen heat retrieval decolors completely.Compared with other methods,it has shorter decoloration time (1 ～ 2min),more than 90％ of completely decoloration rate,the difference was significant(x2 =27.6,23.9,all P ＜ 0.01).Meanwhile,the method dose not damage slides,and the immunohistoehemical results are exact,without background coloring and unusual coloring,antigen expression rate and intensity are high.Conclusion Antigen heat retrieval decoloration not only simplifies the coloration process,but also protects tissue antigen activity better.It is the preferable method of decoloration and protecting antigen resource,which possesses some practical value in the pathology diagnosis.

Objective The author seeked the suitable tidal volume in order to decrease mechanical ventilation-induced lung injury during closed circuit anesthesia in infants.Methodes 50 infants who practiced selective orthopedics operation randomly divided into traditional mode(12~15ml/kg,groupT,n=25)and low tidal volumes(7~8ml/kg,groupL,n=25).The bronchoalveolar lavage fluid of intants were collected immediately after tracheal intubation(T1)and before tracheal extubation,respectively.Interleukin-6 and interleukin-8 in the bronchoalveolar lavage fluid were determined by enhancement solid-phase enzyme immunoassay action(EASIA),TNF-? in the bronchoalveolar lavage fluid were determined by euzymelinked immunosorbent assay(EIA).The numbers of polymorphonuclear neutrophils in the bronchoalveolar lavage fluid of intants were examined.The infants' SpO2,arterial blood pressure and PetCO2 were monitored continuously.Arterial blood gas was analysised.The time of analepsia and complications of lung were observed after operation.Results PaCO2、PetCO2 in groupL were higher than that in groupT,pH in groupL lower than that in groupT at 30 min,60 min,120 min after mechanical ventilation and before extubation,respectively.The contents of PMN,TNF-?,IL-6 and IL-8 in BALF collected at T2 more than that at T1 in groupT.The contents of PMN,TNF-?,IL-6 and IL-8 in BALF in groupL less than that in groupT at T2(P

Objective To investigate the effect of ambroxol administered before surgery on contents of PMN,TNF-?,IL-6 and IL-8 in bronchoalveolar lavage fluid after closed circuit anesthesia in infants.Methods 40 infants who practiced selective orthopedics or abdominal operations were randomly divided into ambroxol group (group A) and control group (group B). Two days before operation,infants in group A and group B were administed ambroxol 0.3 mg/kg or 0.9 normal saline 10 ml through intravenous injection three times per day,respectively .The last single dose was administered before anesthesia induction.The bronchoalveolar lavage fluid of intants were collected immediately after tracheal intubation(T1) and before tracheal extubation(T2),respectively.Interleukin-6 and interleukin-8 in the bronchoalveolar lavage fluid were determined by enhancement solid-phase enzyme immunoassay action(EASIA),and TNF-? in the bronchoalveolar lavage fluid by euzymelinked immunosorbent assay (EIA).The numbers of polymorphonuclear neutrophils in the bronchoalveolar lavage fluid were examined. The contents of PMN,TNF-?,IL-6 and IL-8 in two groups were compared .The time of analepsia and complications of respiratory tract were observed after operation.Results Compared with group A, the contents of PMN,TNF-?,IL-6 and IL-8 in BALF collected at T2 were significant higher in group B (P
