Twenty-eight children with laryngeal papilloma aged 10 months -3.5 yr weighing 8-15 kg received CO2 laser treatment under serf-retaining laryngoscope from May 2003 to May 2007. There were 17 patients without laryngeal obstruction, 7 patients with 1st degree laryngeal obstruction and 4 patients with 2rid or 3rd degree laryngeal obstruction. Different techniques of anesthesia were used for patients with different degrees of laryngeal obstruction. In patients without laryngeal obstruction anesthesia was induced with intramuscular ketamine 5 mg/kg. After the patients lost consciousness midazolam 0.1 mg/kg, ketamine 1-2 mg/kg or fentanyl 2 μg/kg was given iv. Tracheal intubation was facilitated with succinyl-cboline 1.5 mg/kg. In patients with 1st degree laryngeal obstruction, ketamine 5 mg/kg was given ira. The patients kept spontaneous breathing. Tracheal intubaiion was pedormed under topical anesthesia with 1% tetracaine. In patients with 2nd and 3rd degree laryngeal obstruction tracheal intubation was performed awake without any premedication under topical anesthesia with 1% tetracaine. The trachea was intubated with the tracheal tube 1 size smaller than the regular size. Anesthesia was maintained with propofol 3-5 mg·kg1·h-1 and intermittent iv boluses of ketamine 1-2 mg/kg and vecuronium 0.05-0. 1 mg/ kg. Dexamethasone 0.2-0.3 mg/kg was given iv at the end of operation. The patients were extubated when the patients regained consciousness and SpO2≥ 96% on air. In one patient with Ist degree laryngeal obstruction emergency tracheotomy was performed during induction of anesthesia. Anesthesia was otherwise smooth and recovery was uneventful.

Objective To explore the features of verbal working memory in elderly patients with anmestic mild cognitive impairment (aMCI).Methods Thirty patients with aMCI and 30 normal controls (NC), whose age were over 65 years old, were examined with verbal working memory software and the other neuropsychological tests, such as verbal fluency test (VFT) and digit span test.Results The correct rate of visual semantic verbal working memory test was significantly lower in aMCI patients (79.83% ± 3.22% )than in NC ( 87.00% ±: 1.93 % , t = - 1.03, P = 0.002).There was no significant difference of correct rate of the visual phonological verbal working memory test between the aMCI (78.92% ± 8.60% ) and NC (86.80% ±2.14%, t = - 2.34, P = 0.060).Also, aMCI cases achieved significantly lower scores than NC on VFT (22.96 ±2.31 vs 31.53 ±3.72, t = - 1.08, P =0.004) and BDS ( 1.53 ±0.86 vs 3.63 ±0.56, t = - 1.23, P = 0.027).Conclusion The visual semantic verbal working memory is impaired and visual phonetic working memory is saved in aMCI patients.Both scores of verbal fluency test and digit span test are significantly decreased in aMCI patients, too.

Objective To explore the characteristics of prospective memory impairments in patients with Parkinson's disease (PD) at the early and middle stage. Methods Fifteen PD patients at the early and middle stage and 15 normal controls matched with age, sex, education and occupation were asked to complete event-based prospective memory (EBPM) and time-based prospective memory (TBPM) tasks. Results In the EBPM task (points), there was a significant difference between PD patients (3.93±2.69) and normal controls (6.00±2.17, t =-2.318,P <0.05). In the TBPM task(points), there was no significant difference between PD patients (3.47±1.96) and normal controls (3.80±1.70, t= -0.498, P >0.05). Conclusion The EBPM is impaired and the TBPM is relatively spared in early and middle stage PD patients.

Objective To investigate changes in serum level of glial fibrillary acidic protein (GFAP) in patients with Parkinson disease (PD) and its clinical significance. Methods Serum GFAP was determined with sandwich ELISA for 82 patients with PD and acute cerebral infarction (ACI), as well as healthy normal controls. Patients with PD were then divided into two sub-groups in terms of their course duration, one with less than five years and the other with more than or equal to five years. Effects of course duration and age of the patients on their serum GFAP were analyzed. Results Serum level of GFAP was significantly higher in patients with PD [(1.628±0.104) μg/L] and ACI [(1. 637±0. 063 )μg/L] than that in healthy normal controls [ (0. 025±0. 003)μg/L, t = 82. 7, 142. 2, all P <0. 05 ]. But, there was no significant difference in serum GFAP between patients with PD and ACI ( t =0. 214, P > 0. 05 ). Serum level of GFAP in PD patients had no significant correlation with their age. There was no significant difference in serum GFAP between two sub-groups of patients with PD (P > 0.05 ). Conclusions Serum level of GFAP increased significantly in PD patients, as compared to healthy normal controls, but it is not specific. Serum GFAP in patients with PD maintained at certain high level with progression of the disease, indicating effect of astrocytes may persistently exist during the disease course.
