Objective To investigate the effect of different head flexion/extension angles on static sitting balance in normal youth. Methods34 selected healthy college students were measured with the track length of the centre of gravity under eyes closed, head in a neutral position,flexed in 15°, 30°, 45°, and extended in 15°, 30° (30 s each position). Results the average length from small to big were: head flexedin 30°, neutral position, flexed in 15°, flexed in 45°, extended in 15°, extended in 30°. There was no significant difference among the averagelength when head flexed in 30°, in neutral position and flexed in 15° (P>0.05). Conclusion The static sitting balance is the most whenhead put in neutral position to flexed in 30°, and worst in extended in 30° in healthy youth.

Objective To evaluate 1*"H magnetic resonance spectroscopy (1H MRS) in the differentiating recurrent brain gliomas after radiation therapy from delayed cerebral necrosis. Methods Fifteen patients who had clinical and CT, MRI changes that suggested a diagnosis of delayed cerebral necrosis or recurrent brain tumor after radiation therapy and 5 patients who had a definite clinical diagnosis of delayed cerebral necrosis underwent single voxel MR spectroscopy simultaneously both in the lesion′s region and the contralateral side. Results Of the former 15 cases who proved by surgicopathology, 14 cases were gliomas,1case was delayed cerebral necrosis, and their etiologic diagnoses of 1*"H MRS were correct. (1)1H MRS in 14 cases with gliomas exhibited specific spectral peaks including prominent choline-containing compounds (Cho), decreased or absent acetylaspartate(NAA) and total creatine (Cr),and the metabolic ratios showed significantly increased Cho/Cr, decreased NAA/Cr. Twelve cases showed abnormal lactate (Lac). (2)Among 6 cases with delayed cerebral necrosis, 5 cases exhibited decreased or absent Cho, NAA, Cr, and abnormal Lipid, 1 case showed absent Cho, NAA, and Cr with a flat curve without Lac. Conclusion 1H MRS was positively claimed for differentiating recurrent brain gliomas after radiation therapy from delayed cerebral necrosis.

Objective To compare the effect of torasemide or furosemide combined with mannitol in the treatment of acute cerebral hemorrhage patients with cerebral edema.Methods One hundred and sixty patients with cerebral hemorrhage were selected,and divided into torasemide group and furosemide group according to different treatment methods,40 cases in each.The torasemide group was treated with torasemide combined with 20％ mannitol,the furosemide group was treated with furosemide combined with 20％ mannitol.The curative effect,mannitol dosage,edema volume,24 h urine and adverse reactions in two groups were compared.Results The total effective in torasemide group was higher than that in furosemide group [97.5％ (78/80) vs.77.5％ (62/80)],mannitol dosage was less than that in furesemide group [(347.5 ±32.5) ml vs.(438.2 ±30.7) ml],the incidence of adverse reactions was lower than that in furosemide group [7.5％(6/80) vs.27.5％(22/80)],which reached statistical significance (P＜ 0.01 or ＜ 0.05).The edema volume in the 7th,14th day in torasemide group was less than those in furosemide group [(21.1 ±3.4) ml vs.(23.3 ±4.8) ml,(17.6 ±4.5) ml vs.(22.4 ±5.6) ml],the 24 h urine in the 3re,7th,14th day were more than those in furosemide group [(3 684 ±528) ml vs.(3 429 ±592) ml,(3 854 ± 746) ml vs.(3 185 ±490) ml,(3 742 ±t658) ml vs.(2 251 ± 324) ml],which reached statistical significance (P ＜ 0.05).Conclusions Torasemide in treatment of acute cerebral hemorrhage patients has better efficacy and safety.It is better than furosemide.

Objective:To explore the current situation of obtaining high quality and efficient medical service in clinical application of mobile tele-consultation terminal about cell phone. Methods: The technical basis of mobile teleconsultation terminal of cell phone and its application status in domestic and abroad were analyzed. This method was compared with other tele-consultation method at service, mode and cost and other aspects.Results: In the clinical application, mobile tele-consultation terminal about cell phone has many positive roles and advantages, for example, it could enhance the level of diagnosis and treatment for doctor who work in district and community, and resolve medical burden for patients, and promote grading diagnosis and treatment.Conclusion:The mobile tele-consultation terminal can obtain high quality and efficient medical service by investing lower capital. And with the continuous development of the network tele-consultation technique, satellite consultation technique and mobile terminal consultation of cell phone in future, they will further enhance the hospital medical service ability.

Objective To study the effect of Irbesartan on the level of serum high-sensitivity C-reactive protein(hs-CRP) in the patients with acute cerebral infarction(ACI).Methods 60 patients with ACI were randomly assigned to Irbesartan therapy group(n=30) treated with Irbesartan 150 mg/d combined Aspirin 100 mg/d and conventional therapy group(n=30) treated with Aspirin 100 mg/d.Both groups were treated for 14 consecutive days and the other measures of symptomatic therapy were same.And another 30 patients without cerebrovascular diseases were selected as control group.The levels of serum hs-CRP were measured and the scores of neurological deficit(NDS) were evaluated before and after treatment.Results(1) Before treatment the levels of serum hs-CRP of ACI patients in both therapy groups were significantly higher than that in control group(all P

Epidermal growth factor receptor (EGFR) inhibitors are currently widely used for targeted lung cancer therapy. Target-ed therapy evaluation principally relies on genetic testing or rough clinical estimation. PET receptor imaging is highly sensitive and spe-cific. According to domestic and foreign literature, PET imaging using radiolabeled EGFR-targeting agents can be used to predict and monitor therapy response. This paper presents new evaluating methods for targeted lung cancer therapy.

Objective To explore the clinical effect of small cell lung cancer(SCLC) treatment with recombinant human endostatin injection and cis-platinum complexes.Methods 100 patients with SCLC were divided into 2groups.The experiment group used cis-platinum complexes while the control group used recombinant human endostatin injection.Results The effective rate of experiment group was obviously higher than the control group ( 74.0％ vs60.0％,x2=2.16,P ＜ 0.05 ).The median survival time of experiment group was better than control group( t=2.02,P ＜ 0.05 ).The diverse of untoward effect of two groups had no difference ( P ＞ 0.05).Conclusion Recombinant human endostatin injection and cis-platinum complexes were better therapy for SCLC,which had stable effect,no severe untoward effect and overcome the drug-fast of cis-platinum complexes.

ObjectiveTo evaluate the diagnostic performance of bone SPECT and CT fusion imaging in bone metastases from pediatric neuroblastoma.MethodsTwenty-four pediatric patients with neuroblastoma were included in this retrospective study.All patients underwent planar imaging and SPECT integrated with CT.Lesion visibility,diagnostic certainty and diagnostic performance were evaluated with KolmogorovSmirnov test andx2 test.ResultsLesion visibility of SPECT alone,SPECT integrated with CT were significantly better than that of planar imaging ( both H =69.000,P ＜ 0.05 ).SPECT and CT fusion imaging,SPECT alone both detected five more bone lesions than planar bone imaging (77 vs 72).The diagnostic accuracy of SPECT imaging (62.34％,48/77 )was significantly higher than that of planar imaging (45.45％,35/77; x2 =4.416,P ＜ 0.05 ).The sensitivity,specificity and accuracy of SPECT and CT fusion imaging for diagnosing malignant bone lesions were significantly higher than those of planar imaging:82.35％ (42/51) vs 53.19％ ( 25/47),88.46％ ( 23/26 ) vs 40.00％ ( 10/25 ),84.42％ ( 65/77 ) vs 45.45％ (35/77 ; x2 =12.571,14.016,25.667,all P ＜ 0.01 ).The diagnostic specificity and accuracy of SPECT and CT fusion imaging were significantly higher than those of SPECT alone ( 53.85％,14/26 ;62.34％,48/77) (x2 =7.589,9.606,both P ＜0.01 ).However,there was no significant difference of sensitivity between the two methods (x2 =2.942,P ＞ 0.05 ).Diagnostic certainty by SPECT and CT fusion imaging was significantly higher than that by SPECT alone ( H =28.000,P ＜ 0.05 ) and by planar imaging (H =21.000,P ＜ 0.05).ConclusionSPECT and CT fusion imaging can detect more bone lesions in patients with pediatric neuroblastoma.It is helpful for diagnosing bone metastases from pediatric neuroblastoma.
