Objective To evaluate the relationship between the anxiety condition and educational background of the autistic children's parents. Methods Questionnaires for the self-evaluation of anxiety were collected from the parents of 140 children with autism. Results The autistic children's mothers had significantly higher score of anxiety than the fathers (42. 73 ±8. 25) (t =6. 783,P ＜0. 05). The autistic boy's parents had significantly higher anxiety pressure than autistic girl's parents ( 51.38 ± 11.24 vs. 43.23 ± 6. 12) ( t = 4. 894,P ＜0. 05). The anxiety intensity of the autistic children's parents was negatively correlated with the parents'educational background ( F = 10. 788, P ＜ 0. 05 ). Conclusion The autistic children' s parents had certain anxiety,which is correlated with the their educational background and genders of the autistic children. It is necessary to interfere the negative mood to facilitate the treatment of the autistic children.

Objective:To analyze the clincial characteristics and laboratory findings of patients with neurobrucellosis (NB).Methods:Using retrospective analysis, clinical diagnosed patients with NB from June 2016 to February 2019 in Heilongjiang Agricultural Reclamation Bureau General Hospital were selected to analyze the general characteristics, clinical symptoms, laboratory examination results [white blood cell (WBC), hemoglobin(Hb), c-reactive protein (CRP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), total protein (TP), albumin (ALB), cerebrospinal fluid routine and biochemical, serum tube agglutination test (SAT), blood culture and cerebrospinal fluid culture of Brucella] , diagnosis and treatment effect. Results:A total of 25 patients were diagnosed with NB, including 19 males and 6 females, with an average age of (41.7 ± 14.2) years old, ranged from 11 to 70 years old. The main clinical symptoms were fever, headache, joint pain, vomiting and sweating, which accounted for 92.0% (23/25), 88.0% (22/25), 76.0% (19/25), 64.0% (16/25), and 64.0% (16/25), respectively. Positive neck ankylosis and mumbness of lowerlimbs were both 9 cases (36.0%), and mental disorders were 7 cases (28.0%). In 25 patients with NB, the WBC increased in 5 cases (20.0%), Hb decreased in 4 cases (16.0%), CRP increased in 13 cases (52.0%), ALT and AST both increased in 6 cases (24.0%), TP decreased in 21 cases (84.0%); SAT was positive in 25 cases (100.0%), cerebrospinal fluid SAT positive in 7 cases (28.0%); and blood culture was positive in 2 cases (8.0%). Cerebrospinal fluid changes were mainly manifested in 14 cases (56.0%) of chloride reduction, 13 cases (52.0%) of gluose reduction and 19 cases (76.0%) of protein increase. In 25 patients with NB, 17 cases were treated with doxycycline + rifampicin + ceftriaxone, 7 cases with etimicin + rifampicin + ceftriaxone, and 1 case with doxycycline + rifampicin + piperacillin sulbactam. After 6 to 12 months follow-up, 21 cases recovered well, whereas mild sequelae were observed in 4 patients.Conclusion:Clinical features of NB are hetorogeneous, and nerurological symptoms and cerebrospinal fluid examination are of great value in the diagnosis of NB.

Objective To study the effect of flee radical on kidney repedusion injury caused by infra-renal abdominal aorta occlusion in rat model and its possible mechanism. Methods Forty-two healthy Wis-ter rats were randondy divided into 6 groups as following ( n = 7) : the control group( sham group) ; simply isehemia 5 h without reperfusion( group I) ; 2 hours reperfusinn following ischemia 5 h ( I/R 2 h), 4 honrs reperfusion following isebemia 5 h ( I/R 4 h), 8 hours reperfusinn following ischemia 5 h( I/R 8 h) and 12 hours reperfusion following ischemia 5 h ( I/R 12 h). In each group the rats were killed to obtain samples of blood and kidney at the specified time points. The contents of BUN, Cr, MDA, SOD in blood and in renal homogenate were measured in each group. We observed the morphological changes of kidney and muscles of lower limb by light microscope. Results BUN level of serum in model group I, I/R 2 h, I/R 4 h, I/R 12 h were higher obvionsly than those of control group, which were maximal in I/R 4 h, then decreased. MDA level of plasma in model group I, I/R 2 h, I/R 4 h, I/R 8 h, I/R 12 h groups were higher obvionsly than those of control group, which were maximal in I/R4 h group, then decreased. SOD level of plasma in model I/R 4 h, I/R 8 h groups were lower obviously than those of control group; SOD level of renal homogenate in model group I, I/R 2 h, I/R 8 h, I/R 12 h groups were higher obviously than those of group I/R 4 h, which were minimal in I/R 4 h group, then increased. By light microscope: The injury degree of kidney and muscles of lower limb in ischemia group was slight, the injury degree of repedusion group was severer than ischemia group. Conclusion The kidney repedusion injury caused by infrarenal abdominal aorta occlusion in rat model might be concerned with the increase of lipid peroxidatian damage after ischemia-repedusion in-jury of lower limbs.
