Objective To evaluate the sterilization effect of Er:Yag laser irradiation combined with 2%chlorhexidine gel on single tube premolar enterococcus faecalis infection model.Methods After disinfection test was performed without molars bacterial infection,200 single rooted premolar root canal were selected.10μL enterococcus faecalis( ATCC 29212) bacterium suspension were inoculated into single intratracheal with high pressure sterilization and and then were cultured for 2 weeks.200 infected premolar model were divided into four groups:control group (n=50),A group (n=50),B group (n=50) and C group (n=50).The control group did not receive any disinfec-tion treatment,group A received Er:Yag laser irradiation and 2%chlorhexidine gel disinfection,B group received only Er:Yag laser irradiation,the C group received only 2% chlorhexidine gel disinfection.After disinfection,premolars were put into 10mL sterile water,mixed thoroughly,and then 1mL liquid were taken and diluted by10 times.Then the 200μL dilutions lipuid were coated on BHI agar plate,and plate could be selected for counting colony count.Results The average number of colonies was(127 ±12) in the control group,average number of group A(10 ±3) and which was lower than that group C (48 ±6)(t=12.005,P=0.000) and group C (43 ±5) (t=19.277,P=0.000). There were only 2 cases,which had obvious ablation phenomena in group A.Conclusion Disinfection effect of Er:Yag laser irradiation combined with 2%chlorhexidine gel is better than that of Er:Yag laser irradiation or 2% chlo-rhexidine gel disinfection.The incidence rate of the ablation phenomenon was low.

Hypertension in children and adolescents is defined as systolic blood pressure(SBP)and/ or dias-tolic blood pressure(DBP)≥95th percentile for age,gender and height,on at least 3 occasions. Primary hypertension is more common among children of older age or adolescents,while secondary hypertension accounts for more cases for younger children. Among causes of secondary hypertension,renovascular diseases,renal parenchymal diseases,cardio-vascular diseases,and endocrine diseases are common. An initial evaluation can be reached after history taking and physical examination,to decide whether it should be primary or secondary hypertension. Laboratory tests and procedures can further confirm the classification and etiology. There is an increase in prevalence of hypertension in children and adolescents,and an in - time diagnosis and evaluation of hypertension is important to help patients receive a better management of their conditions.

Objective To research the consonant pronunciation of patients with spastic dysarthria as a result of cerebral palsy and supply a theoretical basis for their rehabilitation.Methods Twenty-eight cerebral palsy patients with spastic dysarthria were examined using a dysarthria examination scale developed by the China Rehabilitation Research Center.The whole process of the tests was recorded using Cool Edit recording software.Praat4 was used to evaluate their pronunciation according to the pronunciation criteria of “experimental phonology”.Their error rates on 21 consonants were counted and the characteristics of the articulation errors were summarized.Results According to the location of articulation,the inaccuracy rates on labials,dentals,apicals,blade-palatals,palatals and velars in the 28 patients were 21％,71％,53％,71％,54％ and 36％ respectively.Conclusions Patients with spastic dysarthria as a result of cerebral palsy have the most difficulty pronouncing dentals and blade-palatal consonants.They find labial consonants the easiest.

OBJECTIVE: Superoxide dismutase is one of the families of enzymes which is ubiquitous, and efficiently catalyzes the dismutation of superoxide anions.There are three superoxide dismutases in human brain that are of benefit to ischemic damage. In recent years, transgenic and knockout mutant mice has been widely used in the researches of superoxide dismutases for its protective effect in cerebral ischemia.DATA SOURCES: Using the terms "Chan PH and superoxide dismutase and cerebral ischemia", the relative articles published in the English from January 1991 to December 2003, were identified by searching the MEDLINE database with computer.STUDY SELECTION: The trials with transgenic and knockout mutant mice were identified preliminarily, then all remainders were searched in full content and were divided into intervention group and controlled group, the random cases were accepted, non-random excluded.DATA EXTRACTION: A total of 38 fully studies related to cerebral ischemia and superoxide dismutase were collected, among them, 13 random cases were accepted, and 25 excluded which included 15 repeated studies and 10 irrelevant studies.DATA SYNTHESIS: Reactive oxygen species involved in redox signaling pathways in ischemic cerebral, it can also cause oxidative damage of some macromolecules cell such as lipids, proteins and neucleic acid. In the ischemic brain tissue, overproduced oxygen radicals and consumption of superoxide dismutases lead to tissue damage. Copper-zinc superoxide dismutase, manganese superoxide dismutase and extracellular superoxide dismutase have the same function which can decompose superoxide anion radicals to form H2O2 that are scavenged further, thereby ameliorate edema formation,infarction and cell death, improve the function of ischemic cerebral tissue further.CONCLUSION: Increased oxygen free radicals is an important mechanism in ischemic cerebral damage, all three SOD can ameliorate cerebral ischemia. The protect effect of three superoxide dismutase is related to DNA repairing enzyme, transcription factor, apoptosis proteins and signal transduction pathway.

Objective To investigate the psycho-physiological characteristics of experimental tonic cold and heat pain in a behavioral study. Methods Sixty healthy subjects went through the tonic cold and tonic heat stimulation in a counter-balanced order. Psychological traits were measured before the experiment. Pain intensity ratings were recorded together with continuous Infrared thermal imaging recording. SF-MPQ was employed to assess pain intensity and affective measures. Results Anxiety and fear were positively correlated with cold pain intensity on SF-MPQ,while GESE was negatively correlated with that of heat pain (r =0.57,P <0.05; r =0.45,P <0.05,respectively). Verbal descriptors chosen from SF-MPQ for cold and heat pain significantly differed(χ2=18.6,P =0.04). Infrared thermal imaging results showed after stimulation,heat pain intensity ratings decreased simultaneously with skin surface temperature recovery to baseline. In contrast,skin surface temperature began to return to baseline well before the cold sensation began to diminish(t =34.57,P <0.05; t =23.66,P <0.05). Conclusion Experimental tonic cold and heat pain are not psychophysically identical,but may be predicted by different psychological traits,and may reside in differential peripheral and central processing in human.
