With conventional double-antibody sandwich technique,total IgE level in35 serum samples from malignant lymphoma patients and 35 matched normalcontrols was measured by ELISA.It was found that there was a statisticallyhigher total IgE levels in patients than in the control(p

Objective To study the clinical significance of end-tidal carbon dioxide partial pressure (PetCO2 ) during cardiopulmonary resuscitation (CPR) and seek the fixed value according which to decide if we should and when to give up.Methods This was a prospective,observational study.A total of 124 patients with cardiac arrest in or out-of-hospital from may 2003 to March 2009 in emergency department of our hospital were selected.All of them had definite etiological factors.Changes of PetCO2 in 124 cardiac arrest patients during CPR were tracked.Results The gender,age,rescue time in seventy-one patients with the return of spontaneous circulation (ROSC) after endotracheal intubation have a significant difference with that in fifty-three patients without ROSC (P ＜0.01 ).The PetCO2 of the survival were higher than that of patients without ROSC or with ROSC,but finally died (P ＜0.01 ).A fixed point 14.4 mmHg of PetCO2 after 20 minutes' CPR can be used as a reference value to guide CPR or predict prognosis.Conclusions Monitoring PetCO2 during CPR has a predictive value on the success of resuscitation.

[Objective]To inrestigate the clinical outcomes of using bilateral tibial flap of the second toe nail flap combined with the fibulal flap of the big toe to repair the multi-finger degloving injury.[Method]A variety of different methods were used to repair the multi-finger degloving injury,six fingers in 3 cases were repaired by partial bilateral wrap-around flaps combined with the tibial flap of the second toe.Sixteen fingers in 8 cases were repaired by bilateral second toe nail flap combined with the fibulal flap of the big toe.Six fingers in 2 cases were repaired by bilateral second toenail flap,the fibulal flap of the big toe and the digital arterial island flap.Three fingers in l case were repaired by bilateral second toe nail flap combined with the fibulal flap of the big toe and the the lateral flap of dorsum of foot.Six fingers in 3 cases were repaired by bilateral second toe nail flap and the fibulal flap of the big toe and bilateral dorsum flap of foot.Four fingers in 1 case were repaired by partial bilateral wrap-around flaps and the tibial flap of the second toe and the anterolateral thigh flap.Six fingers in 3 cases were repaired by bilateral second toe nail flap combined with the fibulal flap of the big toe,and bilateral dorsum flap of foot and bilateral anterolateral thigh flap.[Result]Ninety-seven flaps of 98 flaps of 47 fingers in 21 cases were suvived well,with 1 flap developed necrosis.The follow-up duration ranged from 6 months to 9 years in 17 cases (37 fingers).In addition to the activities of DIP limited,the other interphalangeal joint activities were nearly normal.All of the fingernail grew well.Two point discrimination of the fingers was between 5mm and 11 mm.The donor site was hardly affected.[Conclusion]It is a better method using the big toe flap combined with the second toe flap to repair the the multi-finger degloving injury at one stage.

Objective: To identify Aconitum pendulum Busch. and Aconitum kongboense Lauener. Methods: Aconitum pendulum Busch. and Aconitum kongboense Lauener were identified by microscopical identification and TLC. And the contents of aconitine in the two herbs were determined by HPLC. Results:Microscopical identification showed they were different from each other, and aconitine was used as the reference component. Using the solution consisting of hexane ∶ethyl acetate ∶diethylamine (10 ∶6 ∶0. 8) as the developing solvent, the compositions in the two herbs were different in TLC. The content of aconitine in Aconitum pendulum Busch was 0. 71 mg· g-1 , while that in Aconitum kongboense Lauener was only 0. 03 mg·g-1 . Conclusion:Aconitum pendulum Busch. and Aconitum kong-boense Lauener Identified by microscopical identification, TLC and HPLC,SHOW NOTABLE differences between them, and Aconitum kongboense Lauener should not be used as Aconitum pendulum Busch.

Objective To explore the related factors about acute stress responses of the military freshmen,then built a path model among self-efficacy,social support,coping style,state-trait anxiety and acute stress responses.Methods 584 students were tested by General Self-efficacy Scale (GSES),Perceived Social Support Scale (PSSS),Coping Styles Questionnaire,State-Trait Anxiety Inventory (STAI) and Acute Stress Response Scale ( ASP S).Results ①The military freshmen in each factor of acute stress response got a lower score,especially the mean score of the changes of cognition was higher (0.21 ±0.21 ),compared with the other factors,and the changes of pathology (0.053 ±0.114) was lower.②There were significant correlations between self-efficacy,social support,positive coping,negative coping,state anxiety,trait anxiety and acute stress responses (P ＜ 0.01 ).③ Negative coping( r=0.130),trait anxiety(r=0.005) and state anxiety(r=0.002) influenced ASR directly,meanwhile,self-efficacy( r =-1.292) influenced ASR through the state anxiety indirectly,self-efficacy ( r=-7.465 ) and social support ( r =-0.294) influenced ASR indirectly through trait anxiety.Conclusion Acute stress responses of the military freshmen were directly influenced by negative coping and state-trait anxiety,and negative coping style was the main reason.

BACKGROUND:With the consumption of acidic beverages, dental erosion becomes more serious. Erosion is related to direct loss of dental hard tissue, and causes dental over-abrasion, thus great threatening the dental health.
OBJECTIVE:To review the research work on the erosion of human teeth, erosion prevention, and teeth remineralization.
METHODS:A computer-based online retrieval of CNKI, Elsevier and Wiley databases between 1990 and 2013 was performed for articles abut human teeth erosion, erosion prevention and teeth remineralization. After repeated or old literatures were excluded, 58 literatures were included in the analysis.
RESULTS AND CONCLUSION:Current studies on dental erosion included three aspects, firstly, clinical observation of the symptoms and cause of dental erosion;secondly, the erosiveness of common acidic agents;and thirdly, the prevention of dental erosion. Many researchers focused on the prevention of dental erosion. It was suggested that dental erosion could be prevented through adjusting and control ing oral environment, enhancing the erosiveness of acidic beverages, and increasing the anti-erosion capacity of teeth. It should be noted that tooth erosion and friction/wear often occur simultaneously in the mouth. Therefore, future research should pay attention to the interaction mechanism of erosion, friction and wear of human teeth.
