Neonatal nerves exist in tumor tissues,and tumor cells can invade nerve by neurogenesis.Current research shows that cancer cells can secrete cytokines to promote the differentiation and growth of nerve cells,in turn,the differentiation and growth of nerve cells can stimulate tumor development and metastasis.Neurogenesis is one way of interaction bettween tumor cells and microenvironment similar to angiogenesis and lymphangiogcnesis,which has a major impact on biological behavior of tumor cells and prognosis.

Objective To explore the early manifestation of childhood autism.Methods Fifty-one childhood autism were selected as autistic group,and 40 cases of healthy children were selected as healthy control group.All children were investigated retrospectively about social competence,language development,repetitive motor actions and special interests before 18 month-old by questionnaire.All results were analyzed by SPSS 11.5 software.Results Compared with healthy control group,children in autistic group presented a series of abnormal manifestations before 18 month-old,including social competence,language development,repetitive motor actions and special interests(Pa

Spore suspension of Streptomyce s griseus AS 818 (10 6/mL)was radiated b y Co 60 -radiation,the radiation dosage was 1?10 4rad.And 5 streptomy cin resis tant mutants (above 50?g/mL) were screened,then the resistant level of mutant RL-4 was induced to 100?g/mL.The number of RL-4 colonizing on soybean roots pl anted on 1% Water agar or in sterile soil was determined.The results showed tha t it could colonize on soybean rhizosphere and rhizoplane for a short period,bu t there is a little difference.When it was examined in 1% Water agar,the numb er of RL-4 raised gradually in soybean rhizoplane in 4 weeks.But when examined in sterile soil,RL-4 reduced about 100 times at the 1 st week,then raised gradually and reached the highest point at the 3 rd week,and decreased aga in at the 4 th week,In the rhizoplane,it reduced gradually from the 1 st week,and couldn't be examined at the 4 th week. Mutant RL-4 couldn't be found in soybean endorhizosphere by tissue printing.

Objective:To explore the correlation between sexual behavior and potential personality of neurosis patients.Methods:124 cases of neurosis patients were evaluated with Marriage Quality Questionaire,SDS,SAS,self-made Sexual Life Questionaire and TAT.Results:1.The score of neurosis patients with sexual dysfunction on potential personality of TAT were significantly higher than controls.Such ou dominat desire,sexual clesire,assistant clcsire,physical-social attack desire,possession clcstroy desire,self attack cleire,mood change desire and(association,affection-speech attack lure,loss,disppar.loss-support,physical-harm)pressure].The achievement desire is decrease(P

Objective:To explore the effect of psychological intervention on sexual depression of neurotic patients.Methods:90 cases of neurosis patients were randomly divided into experimental group(psychological intervention group)and controlled group after drug-therapy,therapy effect were evaluated with Marriage Quality Questionnaire,SDS,SAS,self-made sexual Life Questionnaire and TAT.Results:1.The SDS and SAS scores in experimental group decreased significantly(P

Objective　To study the relationship between the stress-related psychosocial factors and the psychosomatic symptoms of sterilized women. Methods　120 sterilized women were assessed with Symptom Check List 90(SCL-90),Social Supports Questionnaire(SSQ),Eysenck Personality Questionnaire(EPQ),Psychosocial Stress Scale for Group(PSSG)and a self-developed preoperative cognition scale.Data were analysed with SPSS. Results　There was a significant correlation between scores of psychosomatic symptoms and stress-related psychosocial factors such as EPQ-N,subjective social support(SSS),negative emotion(NE),positive emotion(PE),negative coping style(NC) and some negative characteristics of pre-operative cognition.Multiple stepwise regression analysis showed that EPQ-N,PE and religion belief were in the equation. Conclusion　The results indicated that neurotic syndrome of sterilized women may be mediated or influenced by negative characteristics of cognition,emotion,coping style and personality.

Objective To explore the effects of isoflurane on blood plasma metabolites (BPM) and its correlation with cognitive dysfunction.Methods Thirty female Sprague-Dawley (SD) rats were randomly divided into two groups:rats in the control group (n =10) received 80％ oxygen for 2 hours (h);and rats in the isoflurane-treated group (n =20) were anesthetized with isoflurane and 80％ oxygen for 2 h.Cognitive functions were examined using a Y-maze test to explore the learning times of rats.The level of blood plasma metabolites was detected through gas chromatography-mass spectrometry (GCMS).Results The learning times of rats in the isoflurane-treated group was more than the learning times of rats in the control group [(70.75 ± 15.30) vs (45.40 ± 11.21),P ＜ 0.05].D-fructose,arabinofuranose,n-butylamine,and inositol significantly increased (P ＜ 0.05),respectively.Whereas,L-analine and L-proline significantly decreased (P ＜ 0.05) in isoflurane-treated rats when compared to those in the control rats (P ＜ 0.05).Moreover,plasma concentrations of d-fructose,arabinofuranose,n-butylamine,inositol,and L-proline were positively correlated with the degree of cognitive dysfunction in the isoflurane-treated rats.Conclusions Changes of plasma concentrations of inositol,and d-fructose in aged rats are useful in predicting the occurrence and progression of post-anesthesia cognitive dysfunction.

Objective To understand the potential internet addicts personality traits through the use of Thematic Apperception Test (TAT) and provide evidence for psychological therapy.Methods The experimental group included 34 outpatients defined as Internet Addiction Scale (IAS) ≥ 5 points,and the control group included 34 volunteers with the same age and the common cultural backgroud and defined as IAS ＜ 5 points.Results Compared with the control group,the internet addiction group had a higher desire projects including antisocial aggression (4.83±2.16),substance destroy (2.56± 1.61),intraggression (3.40±2.43) and passivity desires (2.65± 2.29) (P＜0.05).In contrast,the internet addiction group had a lower desire projects including achievements(2.31 ±2.14),domination (1.51±1.29),nurturance (2.30±2.34),succorance (1.80± 1.25) (P＜0.05,P＜0.01).Compared with the control group,the internet addiction group had a higher pressure projects include emotion (3.90±2.81),emotional language offensive attack (3.62±2.18),physical social aggression (2.73±2.23),physical antisocial aggressive (3.95± 1.88),substance destroy (3.33± 1.78),nuturanced (4.53 ± 2.57),rejected (2.18 ± 2.19),loss (4.01±2.41),physical danger pressure (2.65±2.37) and total pressure (49.49± 36.16) (P＜0.05,P＜0.01).Conclusion Internet addiction patients have potential personality with ultra-low in superego,lack in ego,possess stronger in id.Outpatient treatment with internet addicts should focus on psychotherapy,and improve interpersonal relationships.
