Objective To study the reliability and validity of the clinical neurologic deficit scale in evaluating stroke patients. Methods A total of 222 inpatients with acute stroke onset were included in the study. They were assessed when admitted, at the 14th and 90th day of hospitalization by different physicians using the clinical neurologic deficit scale. Intrarater and interrater reliability were determined using Kappa correlation. The split-half rehability and internal consistency were evaluated using Cranbach's a coefficient. Concurrent validity and the predictive validity were determined by spearman rank correlation coefficients. Construct validity was assessed by the factor analysis and the construct validity of the scale was measured according to the classifications of the Oxfordshire Community Stroke Project ischemic stroke subtypes in the patients with cerebral infarction. Results The scores of intrarater reliability in all items were higher than 0.6, the score of interrater reliability in the item "walking" was 0.542, the split-half reliability and the internal consistency were good as demonstrated by the score of 0.911 and 0.886 respectively, and assessment of reliability of different methods showed that "strength in upper limb" and "strength in hand", were poor as shown by the score of 0.393 and 0.386 respectively. The scale is highly correlated with the NIHSS ( both P=0.000) in both total and subtypes of stroke patients according to the classifications of the Oxfordshire Community Stroke Project by concurrent validity analysis. There was a high correlation between the scores of the scale and Barthel Index and the modified Rankin scales at the 90th day of hospitalization (both P=0.000). Conclusions The clinical neurologic deficit scale has a good internal consistency. There is concurrent validity between the scale and the NIHSS and could predict stroke outcome. Factor analysis of the scale displays the best construct validity in the patients with partial anterior circulation infarction, and could be used to evaluate the focus of vertebrobasilar artery despite its insensitivity.

Objective:To evaluate the efficacy of computed tomography (CT)-guided implantation of radioactive ~(125)I seeds in the treatment of residual foci of nasopharyngeal carcinoma after radiotherapy.Methods:Twenty-five nasopharyngeal carcinoma patients who had residual foci after radiotherapy were implanted radioactive ~(125)I seeds from January 2007 to January 2008 in our hospital. Three-dimensional treatment planning system (TPS) was used to calculate the quantity and total dosage of ~(125)I seeds. The radioactive ~(125)I seeds were implanted into residual foci under CT guidance. The dosage distribution of radioactive ~(125)I seeds were verified after surgery. The nasopharyngeal endoscopy CT scans were performed at 3, 6, and 12 months after surgery and the short-term efficacy and adverse reaction were evaluated. Results:Out of the 25 patients, 20 patients had complete response (CR), 2 patients had partial response (PR), 2 patients had no change (NC), and 1 patient had progressive diseases (PD). The overall effective rate (CR+PR) was 88.0%. All patients had no serious postoperative complications. Conclusion:CT-guided implantation of radioactive ~(125)I seed was an effective and safe method in the treatment of the residual foci of nasopharyngeal carcinoma after radiotherapy.

BACKGROUND: Effects of Pericarpium aurantiin water extract on sleeping and spontaneous activity in Kunming mice has been investigated in three experiments, that is, the experiments of sleeping time due to supraliminal and subliminal dosage of sodium pentobarbital, and shaking cage for energy transducer, respectively.OBJECTIVE: To observe the influence of Pericarpium aurantiin water extract on sleeping and spontaneous activity of Kunming mice.DESIGN:Randomized controlled trial.SETTING: The Staff Rooms of Pathology, Physiology and Pharmacology in Gannan Medical College.MATERIALS: The experiment was conducted in the Central Laboratory of Science Research, Gannan Medical College from January through February 2005. Ninety adult Kunming mice, grade of clearness, were enrolled and randomly divided into three groups with 30 mice for each experiment:10 in control group, 10 in large-dosage group and 10 in small-dosage group.METHODS: ① In energy transforming trial, spontaneous activity of mice was recorded, small wave with wave amplitude < 5 mm was considered as the waveform of gentle activity in mice, such as fur licking and tickling; middle wave with wave amplitude of 5-10 mm as the waveform of moderate activity, such as walking, standing, climbing up and down;large wave with wave amplitude > 10 mm as the waveform of intensive activity, such as running, jumping up and down. Mice in the small-dosage group, large-dosage group and control group were respectively given intraperitoneal injection of 5 mg/g, 10 mg/g Pericarpium aurantiin water extract and equal volume of normal saline, and placed into the cage after 15 minutes. Then, 3 minutes later, waveforms of mice within 15 s was recorded. ② In the experiments on duration of sleep in mice due to supraliminal or subliminal dosage sodium pentobarbital, 0.02 mL/g or 0.01 mL/g sodium pentobarbital (2.5 g/L) were administrated intraperitoneally into mice in the small-dosage, large-dosage and control group 15 minutes after intraperitoneal injection of 5 mg/g, 10 mg/g Pericarpium aurantiin water extract and equal volume of normal saline were given to the three groups, respectively. Subsequently, comparisons of the number of sleeping mice, time to falling asleep, and sleeping time were carried out among the three groups.MAIN OUTCOME MEASURFS: ① Times of spontaneous activity, ②Sleeping time due to supraliminal dosage of sodium pentobarbital, ③ Duration of sleep due to subliminal dosage of sodium pentobarbital.RESULTS: All the mice were involved in the result analysis without loss.① There were fewer middle and large waves in the small-dosage and largedosage groups as compared with that in the control group (90.5±14.7,58.3±12.5, 45.6±10.1, t=2.341-3.215; P <0.05 or P <0.01), indicating that Pericarpium aurantiin water extract can evidently inhibit spontaneous activities in mice. ② In comparison with the control group, the time to falling asleep and the duration of sleep due to supraliminal dosage of sodium pentobarbital were shortened and prolonged significantly, respectively,in the small-dosage and large-dosage groups. ③ In comparison with the control group, the time to falling asleep and duration of sleep due to subliminal dosage of sodium pentobarbital were shortened and prolonged significantly, respectively, in the small-dosage and large-dosage groups.CONCLUSION: Pericarpium aurantiin water extract can prolong the duration of sleep and inhibit the spontaneous activities of Kunming mice,which is in cooperation with sodium pentobarbital in central inhibition.
