As the burden of anesthesiology teaching is heavy in undergraduate course, teachers can communicate with the students by nonverbal behaviors, such as eye contact, silent language, facial expression, paralanguage, which can make class atmosphere active, develop harmonious teacher-student relationship, and improve the quality of class teaching. Teachers of anesthesiology should take some measures, such as rehearsing lessons, summing up the experience of the lessons in time, accu-mulating the experience of nonverbal behaviors, and doing some exercise for the nonverbal behavior as much as possible, so as to set up an excellent atmosphere for teaching ,and meanwhile improve the quality of anesthesiology teaching.

PURPOSE: It was reported that gene locus for generalized epilepsy with febrile seizures plus(GEFS+) exist in chromosome 19q13.1, and has relationship with a 387 C G mutation in the SCN1B gene. This study is to determine whether there is the 387 C G mutation in the children with GEFS+ and simple febrile seizures(FS). METHODS: The sample group consisted of 16 patients with GEFS+ and 10 patients with FS who were diagnosed by our department of pediatrics from Jan. 1998 to Dec. 1999. The control group consisted of 15 children who do not have seizure disorders. Genomic DNA was extracted from peripheral blood and a segment of the SCN1B exon 3 was amplified by PCR technique. Purified PCR products were treated with restriction enzyme, Hin P1. The restriction pattern was analyzed by sequencing analysis. RESULTS: Sixty nine%(11 of 16) patients with GEFS+ had family history for epilepsy, and epilepsy phonotypes were generalized tonic-clonic seizures in 82%(13 of 16), on the other hand 12%(2 of 16) and 6%(1 of 16) had absences and atonic seizures respectively. EEG findings showed generalized spike and wave in the all patients with GEFS+. in this study, however we could not observe a 387 C-->G mitation of the SCN1B in the children with GEFS+ and febrile seizures. CONCLUSION: The gene for GEFS+ may have a heterogenetic characteristics, and there may be racial differences in mutation frequency. Expanded studies involving large number of different families are required.

Objective To perform literature search and review on the controversial relationship between therapies of hyperthyroidism due to Graves'disease(GD)and the course of Graves'ophthalmopathy(CA)).Methods We searched the database of MEDLINE(1966-2006.3),EMBASE(1984-2005),Cochrane Library(2006 No.1),CBMdisc(1978.1-2006.4)and CNKI(1994-2006).The methodological quality of the studies selected for review was assessed according to the quality assessment criteria suggested by the Cochrane systematic review guideline.Meta-analysis was performed by RevMan 4.2 software.Results Eight studies were included in the systematic review.Meta-analysis showed that there was statistically significant difference between 131I and other forms of therapy[surgery or antithyroid drugs(ATD)](test value:2.31,5.97,3.70,5.55;all P＜0.05)in aggravation of exophthalmos and symptom improvement in patients without receiving thyroxine during the early stage to prevent hypothyroidism.However,there was no statisti cally significant differenee in the above relationship between surgery and ATD therapy in those patients already receiving thyroxine supplement(test value:0.27,0.99;all P＞0.05).There were not yet any studies on the impact between early prevention of hypothyroidism after 131I therapy and GO.Conclusions Based on meta-analysis on literature data,if early measures are not performed to prevent hypothyroidism after 131I therapy,it may induce or aggravate GO more frequently than ATD or surgical treatment.Symptomatic relief of GO after 131I therapy is also less effective than the other 2 forms of therapy.Therefore.131I therapy should be delivered carefully in those patients with GO.

Objective To compare the biomechanical properties of single-segment and two-segment fusion for Denis type B spinal fracture.Methods Two female patients with Denis type B L1 vertebral fracture were enrolled in this study.The 45-year-old patient (Frankel B) underwent posterior reduction and fixation with pedicle screw system plus anterior two-segment fusion and the 41-year-old patient (Frankel C) underwent posterior reduction and fixation with pedicle screw system plus anterior one-segment fusion.The intervertebral fusion was achieved in both patients 1 year after operation.CT data of the two patients at 1 year after surgery was collected,including data of 41-year-old patient before and after removal of pedicle screws and data of 45-year-old patient without removal of pedicle screws.These three sets of data were imported into the Mimics software to establish T11-L2 three dimensional models.After construction of the models,they were imported into ANSYS software.An axial load (260 N) and 10 Nm torque were loaded to simulate the flexion,extension,lateral bending and rotation of the spine,respectively.Meantime,under above 6 kinds of motion form,the average displacement of the spine and the average Von Mises stress of T11-12 intervertebral disc were recorded and compared.Results There was no significant difference in the average displacement of the spine between two-segment fusion patient and single-segment fusion patient without removal of pedicle screws.However,under all motion forms,the average displacement of the spine of single-segment fusion patient after removal of pedicle screws was significantly higher than that before removal of pedicle screws and that of two-segment fusion patient.The average Von Mises stress of T11-12 intervertebral discs of two-segment fusion patient was significantly higher than that of one-segment fusion patient.Moreover,the average Von Mises stress of T11-12 intervertebral discs of single-segment fusion patient before removal of pedicle screw was higher than that after removal of pedicle screw.Conclusion Under the premise of satisfactory interbody fusion,removal of pedicle screws after one-segment fusion can increase spinal motion,reduce the stress of the adjacent intervertebral discs and delay disc degeneration.

Objective To make a plan for the backup of electronic medical records. Methods The background of electronic medical records backup was analyzed, and NTBACKUP tool and batch technology were used to realize the backup plan. Results An automatic-execution backup plan raised the security of electronic medical records greatly. Conclusion The automatic-execution backup plan satisfies the basic demands for medical information security, though there is room for further improvement in data synchronization.

Objective To optimize an integration technique for extracting the liposoluble and water-soluble components of Salvia miltiorrhiza. Methods Salvianolic acid B and Tanshinone ⅡA were selected as marker components and determined by HPLC to optimize the integration extract process of Salvia miltiorrhiza by orthogonal test. Results The liposoluble and water-soluble active components of Salvia miltiorrhiza were efficiently extracted by the optimum integration technique. The integration technique for extracting was obtained:Salvia miltiorrhiza was added with 8 times alcohol of 70% and extracted 1 hour for 2 times. Conclusion The liposoluble and water-soluble active components of Salvia miltiorrhiza can be extracted simultaneously by the novel extraction process which was reasonable and feasible. This new technique can be employed to reduce time, working and energy, and be suitable for the morden production.

Objective :To explore the behavior characters of children diagnosed as ODD with ADHD symptoms. Methods: The diagnosis of ODD was made according to the ICD-10 criteria . 40 Children having ODD with ADHD symptoms (combined group ) and 22 Children having ODD but without ADHD symptoms (ODD group) were collected from outclinics. The parents of all subjects completed Achenbach Child Behavior Checklist (CBCL) and a family information list. Results: The onset and help-seeking age of the combined group were younger than that of ODD group. They had more disobey, attacking, and extroversive behaviors. Their fathers were more agitative. Parents of the combined group used more beating and scolding in parenting. Conclusion: ODD children with ADHD symptoms had more behavior problems and incur worse parenting style. Their family need more help in early age.
