Objective To investigate surgical indications,techniques and effects for intraeranial arachnoid cyst in children. Methods Clinical data from 82 surgical cases were analyzed retrospectively,and different methods of operation were analyzed comparatively.Four operation-methods were adopted,in which cyst removal were performed in 19,cyst removal plus cisternal opening in 23,cyst-peritoneal shunt in 28,and cyst-peritoneal drainage in 16.Results Upon following up from six months to five years after operation,the chief symptoms got improved in 89.0% of the patients,and CT or MRI scan showed that the size of cvst became smaller in 72 of the patients.Four operation methods were compared,cyst removal was not better than the other three operation methods.Conclusions The treatment of operation methods could make the svmptoms improved and the cyst thrunk of intracranial arachnoid cyst in children.The operation of cyst removal plus cisternal opening or cyst-peritoneal shunt and cyst-peritoneal drainage is preferred.

BACKGROUND: Gene therapy is a popular topic in domestic and overseas studies on biological therapy for brain tumor.OBJECTIVE: By using a newly constructed eukaryotic expression vector of pCR3-TK, the effect of the HSV-TK/ACV system on the proliferative activity of human glioma cells was investigated.DESIGN: Experimental study based on cells.SETTING: Department of neurosurgery and department of oncology in a university hospital.MATERIALS: The study was conducted at the National Key Laboratory of Veterinary Biotechnology of Harbin Veterinary Research Institute from January to April in 2004. The eukaryotic expression vector of pCR3-TK was constructed by the author. The TJ905 strain was a gift from professor Pu Pei-yu, who worked in the Neurology Institute of Tianjin city. The nontransfected cells and the cells transfected with pCR3-Uni vector were set as controls.METHODS: By using Lipofectamine(a cationic liposome), the pCR3-Uni vector and the recombinant pCR3-TK plasmid(inserted with HSV-TK gene)were transfected into the human glioma cell strain-TJ905. Then the positive clones were picked out and were given ACV(50 mg/L) . Totally 72 hours later, the cover slips were collected and silver staining for nucleolus organizer regions(AgNORs) was performed.MAIN OUTCOME MEASURES: After the ACV treatment and AgNORs staining, the numbers of silver-stained granules in TJ905 cells with or without transfections were counted respectively.RESULTS: In those cells transfected with HSV-TK gene, after ACV treatment, a significant decreasing in proliferative activity could be observed, and the average numbers of the silver-stained granules in cells transfected with pCR3-Uni or pCR3-TK were 14.33 and 6.67 respectively( P ＜ 0.01).CONCLUSION: As an easy-to-operate method, AgNOR counting is helpful for the studies on the proliferative activity of cells and the investigations into the potential anti-tumor mechanism of the HSV-TK/ACV system.

Objective To investigate the computer-assisted cognitive training (CACT) on cognitive function and functional independence of stroke patients. Methods Sixty patients were randomly divided into 2 groups: the CACT group and the control group. All patients received routine training. Patients in the CACT group received computer-assisted cognitive training additionally. Before and after the CACT, the cognitive function and functional independence of patients were assessed by MMSE, MoCA and FIM assays. Results Before the CACT, no significant differences in the scores of MMSE, MoCA and FIM were found between the two groups (P > 0.05). After the CACT, scores of MMSE, MoCA and FIM were improved in both groups, especially in the CACT group, with statistical differences (P < 0.05). Conclusions CACT can help improve the cognitive function and functional independence in stroke patients.

Objective To evaluate and compare the clinical outcome of coracoclavicular screw and double Endobutton plate in treatment of acromioclavicular dislocation ( Rockwood Ⅲ-Ⅴ ). Methods Twenty-eight patients with Rockwood Ⅲ-Ⅴ acromioclavicular dislocation were subjected to surgical reconstruction from January 2008 to October 2009. The coracoclavicular screw was performed in 14 patients and the double Endobutton plate in the other 14 patients. Clinical evaluation was performed by using Constant score and subject should value (SSV) in both groups, and the preoperative and postoperative radiographs, curative effects and complications were compared. Results The patients in two groups were followed up for a range of 6-25 months (average 12.6 months) , which showed higher postoperative Constant score and SSV score than preoperation in both groups (P＜0.05). But the postoperative Constant sore and postoperative SSV score in the double Endobutton group were (89.8 ±8.3) points and (85.7 ±7. 3) points respectively, significantly better than (78. 0 ± 10. 3) points and (71. 8 ±9. 7) points respectively in the coracoclavicular screw group ( P ＜ 0.05). The radiologic measurement showed no significant difference in regard of the coracoclavicular distance three months after operation in two groups (P＞0.05). Conclusions The double Endobutton plate can attain significantly superior clinical outcomes for Rockwood Ⅲ-Ⅴ acromioclavicular dislocation compared with the coracoclavicular screw. The surgical technique of reconstructing the coracoclavicular ligament through anatomical approach will be the future trend in treatment of the acromioclavicular joint dislocation.

Objective To investigate the requirement and the attitude of the mental health knowledge and some psychological factors indifferent developed regions. Methods The mental patients, their caregivers and normal people in total of 534 were surveyed with the Zung'sSelf-rating Depression Scale, the Questionnaire of Experience and Attitude of the Psychosis (self-edited), the Questionnaire of Requirementand Attitude on Mental Health Knowledge (self-edited), the Social Support Rating Scale and the Simplified Coping Style Questionnaire. Theresults were compared between the developed and the developing regions. Results Compared with those from developing, the requirementwas more and the attitude was more positive on mental health knowledge in all the people from the developed regions; the patients obtainedand applied more support, and took more positive coping style, less depressive emotion; the caregivers took more positive and negative copingstyles, and more depressive emotion; the healthy people applied more support, and took more positive coping style; the caregivers feltmore un-safety and wished the patients stay in hospital longer. Conclusion Development of the region plays a role in the mental health. Thecaregivers need more support and care.

ObjectiveTo analyse the requirement and attitude to mental health knowledge and the influence factors among the psychosis patients, the caregivers and the healthy pepople.MethodsThe questionnaire survey conducted among the psychosis patients, the caregivers and the healthy pepople from 12 communities which served as the stations for the psychosis where 12 prefectures were organized uniformly by Guangdong Provincial Federation of Disabled Persons.Results1080 sheets of questionnaire were provided, and 986 replied to meet the requirements. The caregivers showed significant difference in requirment and attitude to mental health knowledge compared to the psychosis patients and the healthy pepople(P＜0.05-0.001). The main influence factors were cultural education, regional economic, the frequency of inpatient, the anxiety emotion of the caregivers, which were statistical significance(P＜0.05-0.001).ConclusionIt is lack in the requirement and cognition to mental health knowledge among the psychosis patients, the caregivers and the healthy pepople. Cultural education and economic development are the effective measures to improve the level of the mental health knowledge.

Serum p-amyloid peptide(Aβ)40 and Ap42 levels in patients with type 2 diabetes mellitus (T2DM)and atherosclerosis(AS)were detected by ELISA.The results showed that serum Ap40 level in T2DM group was significantly higher than that in the control group[(274.70±159.51 vs 162.63±87.58)pg/ml,P<0.05],especially in the diabetic patients accompanied with AS[(616.95±195.13)pg/m],P<0.01].Serum Ap40 level in simple AS group was also higher than that in control group[(318.52± 188.65)pg/ml,P<0.05].These results suggest that Ap40 is a risk factor of T2DM complicated with AS.However,there was no difference in serum Ap42 levels among various groups.

Objective To analyze the family burden of the caregivers of the psychosis patients in community, and the psychosocial factors which influence the family burden.Methods Conducted some questionnaires to survey the requirement and attitude on mental health knowledge,social support,family burden and coping style of the caregivers of the psychosis patients from the twelve communities which served as the stations for the psychosis of the twelve prefectures organized uniformly by Guangdong provincial disabled federation.Results 360 questionnaire was provided,and 308 replied to our questionnaire effectively.The mean score of each single item of the family burden questionnaire was beyond the moderate.The factor score of the economy burden was the highest among the factots of the economy burden(2.33±0.52),the daily activity of the family(2.17±0.53),the recreation activity of the family(2.00±0.58),the family relationship(2.10±0.54),the body health of the family members (2.03±0.65),and the mental health of the family members(2.09±0.68).The bad emotion and experience with the patients aggravated some factors of the family burden(P<0.05～0.01).According to correlation analysis and regression analysis,there were significant relation and impact between family burden with the requirement and attitude on mental health knowledge,subject support,coping style,age,economy,culture and so on(P<0.05～0.01). Conclusion Negative assumption to mental health will aggravate the family burden,transfering the positive message and changing passive coping style will help to reduce the family burden.

Background Choroidal hemangioma is a common benign intraocular tumor.Typical choroidal hemangioma is comparably easy to diagnose,but untypical one might be misdiagnosed as malignant tumor.Contrastenhanced ultrasound (CEUS) has been used to diagnose multiple neoplasm for the past few years.However,the application of CEUSin ophthalmology is less.Objective This study was to investigate the CEUS characteristics of choroidal hemangioma.Methods Fifty-eight eyes of 58 patients who were diagnosed as choroidal hemangioma were included in Beijing Tongren Hospital during July 2010 to December 2012.CEUS was performed on the patients to check the manifestations of choroidal hemangioma.A time-intensity analysis was employed to quantitatively analyzed and compared the maximum intensity (MI),rising time (RT),time to peak (TTP),and mean transit time (mTT) between the choroidal hemangioma and normal orbital tissue and the parameters were contrasted using Wilcoxon signed-rank test.Results CEUS showed that choroidal hemangioma was gradually enhanced by the contrast after intravenous injection of sulphur hexafluoride microbubbles with a high-reference signal in choroidal hemangioma,and the fading procedure was slower in choroidal hemangioma than that of normal orbital tissue.MI,RT,TTP,and mTT were294.20％ (217.35％,373.25％),21.30 (17.35,23.35) s,25.00 (21.68,27.48) s and 59.30 (51.08,78.35) s in the choroidal hemangioma,which were significantly higher than 100.00％ (100.00％,100.00％),17.75 (15.00,20.30) s,22.40 (18.35,24.63) s and 47.25 (40.90,57.23) s in the normal orbital tissue (Z =-6.608,-4.998,-4.650,-4.332,all at P＜0.001).Conclusions Choroidal hemangioma has its own CEUS manifestation characteristics.CEUS is helpful to the differential diagnosis of choroidal hemangioma.
