BACKGROUND:Hyperbaric oxygen as a wel-recognized therapy for ischemic and hypoxic diseases has to be combined with other treatments. OBJECTIVE:To study the effects of hyperbaric oxygen combined with neural stem cel transplantation via tail vein in chronic stress depression rats. METHODS:Of 60 Sprague-Dawley rats, 15 rats randomly selected were given no treatment as normal group, and the rest 45 ones were used to establish a rat model of depression and randomly divided into three groups:model group (n=15, without giving any treatment), neural stem cel group (n=15, injection of 1 mL neural stem cel suspension (3×106) via the tail vein) and combined group (n=15, hyperbaric oxygen treatment plus neural stem cel injection). Hyperbaric oxygen treatments were carried out four times per day, for 1 week, and al the treatments were given 24 hours after modeling. Rats in each group were subjected to body mass measurement and sugar water consumption test 1 and 2 weeks after treatment, and open field test within 5 minutes after treatment to observe rat behavior changes. The survival and distribution of CM-Dil labeled neural stem cel s were observed by fluorescence microscopy. The changes in the size, morphology and number of hippocampus neurons in rat were detected by the method of nylon staining. TUNEL method was used to measure the apoptosis of nerve cel s. RESULTS AND CONCLUSION:Compared with the normal group, in the model group, rat’s body weight, sucrose water preference and open field test scores were significantly lower, reduced number of hippocampal neurons with intact structure was found and TUNEL results showed more apoptosis (P<0.05). Compared with the model group, the body weight, sucrose preference and open field test score increased significantly (P<0.05), the number of hippocampal neurons was increased, while the number of apoptotic cel s was reduced significantly in the neural stem cel and combined groups (P<0.05). Compared with the neural stem cel group, these indexes were improved more significantly in the combined group (P<0.05). More CM-Dil positive cel s were found in the combined group than the neural stem cel group (P<0.05). Additional y, the number of hippocampal neurons was higher in the combined group than the neural stem cel group, but lower than the normal group. To conclude, transplantation of neural stem cel s combined with hyperbaric oxygen can improve the depression behavior and apoptosis in the hippocampal neurons in chronic stress depression rats.

Objective To compare the risk factor of chilldren with autism and ordinary children during perinatal period. Methods One hundred and fourty children with autism and 82 ordinary children were reviewed by self-written general circumstance questionnaire and risk factor questionnaire. Results Viral influenza during pregnancy (x2 =15.29) ,bom suffocate( x2 =6. 04) , premature delivery (x2 =6. 48) , dystocia (x2 =2. 83) and artificial feeding ( x2 = 6. 02 ) were risk factors for children autism (P < 0. 05 ). Conclusion Childeren autism is associated with risk factors in rinatal period. Early dectecion and early prevention and treatment may improve the outcome.

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 observe clinical efficacy and safety of citalopram in the treatment of depression patients after lung cancer operation. METHODS:114 depression patients after lung cancer operation were selected and randomly divided into observa-tion group and control group (n=57). Control group was given routine treatment as nutrition support and electrolyte balance,but had no anti-depression drugs;observation group was given Citalopram tablet 20 mg orally,qd. Two groups were treated for 6 weeks. Clinical efficacy,HAMD and HAMA scores,each score and total score of SF-36 were observed before and after treatment. The occurrence of ADR was recorded. RESULTS:The total effective rate of observation group was 87.72%,which was significant-ly higher than that that of control group(71.93%),with statistical significance(P<0.05);there was no statistical significance in HAMA score,HAMD score,each score and total score of SF-36 between 2 groups before treatment(P>0.05);HAMA score and HAMD score of 2 groups decreased significantly after treatment,the observation group was lower than the control group;each score and total score of SF-36 increased significantly,the observation group was higher than the control group,with statistical sig-nificance(P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Citalopram is effective and safe for depression af-ter lung cancer operation,can improve mental state and quality of life.
