Objective:To compare the assessments on hyperkinetic syndrome of ADHD between teachers and psychiatrists,in order to determine their roles in our later study about ADHD.Method:Pediatric psychiatrists from Guangzhou psychiatric hospital and pre-occupational or experienced teachers from Fangcun elementary school(30 in each group)rated the presence and degree of hyperactive-disruptive behaviors in a standardized videotape,showing one 7-year-old boy who participated in individual and group activities.The results were compared between each group.Results:There was no significant difference on most of the assessments between psychiatrists and experienced teachers.The assessments of pre-occupational teachers had significant differences to the results of the above two groups.Conclusion:The assessments of experienced teachers may be used as very important information on the early diagnosis and the assessments of effectiveness of medical intervention for ADHD children.

BACKGROUND: The association of tumor necrosis factor alpha (TNF-α) gene polymorphisms with the onset and development of ankylosing spondylitis (AS) has been the focus of studies on AS in the field of genetics.OBJECTIVE: To explore the association of the polymophisms of TNF-α promoter gene at positions-308 and -238 with AS susceptibility and clinical pathological changes.DESIGN: A case-control study.SETTING:The Rheumatic Immunology Department of Changhai Hospital of the Second Military Medical University of Chinese PLA.PARTICIPANTS: Totally, 108 AS patients were recruited from Rheumatic Immunology Department of Changhai Hospital, Second Military Medical University of Chinese PLA from January 1999 to December 2003 ,they had no kinship. The ratio of men to women was 5.3: 1. They aged from 13 to 71 (30-± 12) years old, and AS was divided into Ⅰ- Ⅳ radiographic stages according to the sacro-iliac joint damage. A total of 100 healthy controls were randomly selected from the blood donators(Shanghai Hospital) who were aged from 19 -56 (33 ±9) years old, and the ratio of men to women was 4.9: 1. Informed consent was obtained from all the subjects.ti-coagulated with EDTA. Polymerase chain reaction amplification and purification of the TNF-α promoter region was made and the sequence of polymerase chain reaction products was examined and displayed by Chromas 1.62 softcorresponding radiographic stage of sacro-iliac joint damage was assessed to investigate the influence of gene polymorphisms on AS.MAIN OUTCOME MEASURES: DNA direct sequencing method was used to detect -238 and -308 allele phenotypes for investigating the association with clinical presentations.G and -238G/A allele was 98.1% (106 cases) and1. 9% (2 cases) respectively in AS group and 95.0% (95 cases) and 5.0% (5 cases) respecquency of TNF-α promoter gene at positions -308. 1.1(G/G) and - 308.1.2(G/A) alleles was 82.4% (89 cases) and 17.6% (192 cases) respectively in AS group, which was not significantly different compared respectively with 85.0% (85 cases) and 14.0% (14 cases) of the control of sacro-iliac joint damage and the frequency of TNF-α promoter gene at the position of - 308 (G/G) and (G/A): AS patients with(G/G) phenotype who were confirmed of radiographic stage Ⅰ, Ⅱ, Ⅲ, and Ⅳ were observed in 3/35/40/11cases,compared with (G/A) phenotype of 1/12/6/0 cases.The difference was statistically significant (χ2GMH = 4.77, P ＜ 0.05 ).CONCLUSION: Our data suggest that the polymorphisms of TNF-α promoter gene at positions of - 238 and - 308 allele has no association with AS susceptibility, but the polymorphisms of TNF - α promoter gene at the position of -308 might exert great influence on AS according to the radiographic stage of sacro-iliac joint damage.

AIM: To investigate the changes of L-arginine/nitric oxide(L-Arg/NO) pathway and the characteristics of L-Arg transport in erythrocytes (RBC) in patients with essential hypertension(EH). METHODS: 12 EH patients were studied with 10 normotensive people as control. The nitric oxide (NO) production was assayed by measuring the nitrite in medium using Greiss reaction. NO synthase activity was measured according to the method described by Ghigo. In order to achieve zero-trans condition, erythrocytes were incubated at 37℃ for 3 h and then L- Arg transport of RBC were determined by measuring the influx of radiolabelled L-arginine by Deliconstantins described method.RESULTS: In EH patients, NO production was lower than that in control (P

Objective To explore the effects of no convulsions electric shock treatment on cognitive function in patients with schizophrenia. Methods Sixty patients with schizophrenia from Jan 2012 to Apr 2014 were randomly divided into two groups. Observation group patients were treated with MECT and new anti-psychotic while control groups just with new anti-psychotic. The corresponding index were compared. Results The first treatment week: BANS scores of the observation group were significantly higher,while PANSS,TESS etc were significantly lower than the control group (vi-sual spatial structure was opposite) (P﹤0.05); Connect test completion time and errors numbers of control group were significantly lower than the one of observation group(P﹤0.05). One week after treatment:RBANS scores of observation group was significantly higher,while the PANSS, TESS scores were significantly lower than the control group(P﹤0.05);Connect test completion time of control group were significantly higher than the one of observation group. Conclusion Schizophrenia patients with non-convulsive electric shock treatment,have a greatly recovery,but the presence of cogni-tive function exist reversible injury.

Objective To investigate the safety and feasibility of en-bloc resection of a primary sacral chordona based on a 3-dimensional printing model.Methods 31 patients with primary sacral chordoma underwent en-bloc resection via a onestage posterior approach or combined anterior and posterior approaches in our oncology department from January 2013 to December 2014.They comprised 21 males and 10 females of mean age (49.2±12.5) years (range,26-67 years).Preoperative 3-D printing models were created by 3D printing technology,it included tumor tissue,the around vascular and nerves involved in sacral chordoma.The sacral chordomas were en-bloc resection with decompression and internal fixation.Results With the mean (29.0±6.8)months follow-up (range from 19 to 41),all patients underwent en bloc excision via 26 cases with posterior approach,5 cases combined posterior and anterior approaches in one stage.The mean operative time and estimated blood loss were (275.0±58.1) min and (3 250.0±1 304.4) ml,respectively.The visual analogue scale (VAS) score was (5.6±1.9) in average (range from 3 to 9) at preoperation,and (2.0±1.5) at post-operation,which was significantly lower than that of preoperation,and the pain was relief obviously.There were 13 cases in grade C,11 cases in grade D,7 cases in grade E of American Spinal Injury Association (ASIA) grade neurological function before surgery,compared with the pre-operation,there were 5 cases in grade C,6 cases in grade D,20 cases in grade E of post-operation,which was significantly improved.MSTS (Musculoskeletal Tumor Society) 93 score was 6-29 points (20.0％-96.7％) at the follow-up 3 months after surgery,with the average of (19.8 ± 5.8) points,which excellent in 8 cases,good in 14 cases,general in 5 cases,poor in 4 cases.Two cases of dysporia for the reasons of resecting on one side of the S1,2 nerve roots involved by the sacral chordoma,after sacrificing the nerve root of complete tumor resection,the urine left dysfunctional,while the pain of other 29 patients were thoroughly relief after surgery.The ones were relieved with the disturbance of sensation of the perineum before the operation.2 cases were recovery of leakage of cerebrospinal by the drainage of lumbar cistern with normal temperature.One hypostatic pneumonia patient was cured by anti-inflammatory.One with the urinary infection got better by the effective bladder irrigation,which had diabetics mellitus with the bladder stoma before.1 case of skin necrosis due to vascular thrombosis before operation,recevied flap translocation half month after surgery,got recovery 3 months later.Only one underwent tumor resection for the recurrence at 15 months follow-up.Conclusion It is feasible and safe to perform en bloc resection of primary sacral chordoma.This is the most effective means of managing method of the marginal resection of the tumor.Preoperative 3-D printing modeling enables better anatomical understanding of the relationship between the tumor,and can avoid vascular and nerves tissue injury,which can also assist in planning the surgical procedure,and be worth recommendation.

Objective To compare the clinical efficacy of ibuprofen arginate,a new nonsteroidal antiinflammatory drug,with that of ibuprofen,in patients with rheumatoid arthritis or knee osteoarthritis and to evaluate the safety and tolerability of ibuprofen argihate.Methods This is a muhicenter,random,open,active comparator-controlled,parallel clinical trail in which 171 patients with rheumatoid arthritis or knee osteoarthritis were enrolled.Patients were randomized to 2 groups:400 mg of ibuprofen arginate three times daily and 400 mg of ibuprofen three times daily respectively.Clinical efficacy and safety were evaluated after 4-week treatment.Results Ibuprofen arginate,at dosages of 400 mg three times daily,had shown significant efficacy in relieving pain,tenderness and swelling of joints and there was no significant difference when compared to that of ibuprofen.There was no difference in clinical adverse effects between the two groups and no serious adverse effects were repofled.But ibuprofen arginate could initiate effectiveness more rapidly than ibuprofen in both rheumatoid arthritisand osteoarthritis patients.Conclusion Ibuprofen arginate has the same clinical efficacy and safety profiles as itmprofen in treating rheumatoid arthritis and osteoarthritis.However,its onset is more rapid than ibuprofen.

OBJECTIVE: To investigate the clinical outcomes of patients with aneurysmal subarachnoid hemorrhage (aSAH) after surgeries in Yunnan Province. METHODS: We retrospectively analyzed the demographic features, vascular risk factors, severity at admission, and aneurysm locations in 85 patients with aSAH receiving surgical interventions in Yunnan Province. All the patients were treated by aneurysm clipping or coiling and followed up for clinical outcomes and recovery of daily activities evaluated by modified Rankin Scale (mRS) and Activities of Daily Living (ADL) scale, respectively. RESULTS: Thirty-four of the patients (40.0%) underwent aneurysm clipping and 51 (60.0%) underwent aneurysm coiling. During a median follow- up period of 66.23 months (IOR, 12.03 months), 84.7% of the patients had low mRS scores, and 78.8% lived independently. The WFNS grade at admission was significantly correlated with the follow-up mRS scores (95%: 1.48-19.09, =0.011) and ADL (95%: 2.55-28.77, < 0.001). Multivariate analysis showed that age (95%: 1.02-1.23, =0.017; 95%: 1.00-1.15, =0.038) and a high WFNS grade at admission (95%: 2.19-141.48, =0.007; 95%: 2.84-82.61, =0.002) were independent predictors of both mRS and ADL scores at follow-up. There was no significant difference in clinical outcomes or the length of hospital stay between the two treatment strategies ( > 0.05), but the cost of hospitalization was significantly higher in coiling group than in the clipping group ( < 0.001). CONCLUSIONS Both aging and a high WFNS grade at admission are associated with a poor prognosis of aSAH, for which aneurysm clipping and coiling have similar long- term outcomes, but for patients with a high WFNS score, aneurysm clipping is favored over coiling in terms of health economics.

The adjacent anatomy of the pelvis is complicated, with digestive, urinary, reproductive and other organs as well as important blood vessels and nerves. Therefore, accurate resection of pelvic tumors and precise reconstruction of defects after resection are extremely difficult. The development of medical 3D printing technology provides new ideas for precise resection and personalized reconstruction of pelvic tumors. The “triune” application of 3D printing personalized lesion model, osteotomy guide plate and reconstruction prosthesis in pelvic tumor limb salvage reconstruction treatment has achieved good clinical results. However, the current lack of normative guidance standards such as preparation and application of 3D printing personalized lesion model, osteotomy guide plate and reconstruction prosthesis restricts its promotion and application. The formulation of this consensus provides normative guidance for 3D printing personalized pelvic tumor limb salvage reconstruction treatment.
