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.

0.05).The off-pump group had a shorter respiratory support time [(4.8?1.9)h vs(8.9?2.1)h,t=17.453,P=0.000],less drainage volume[(390?152)ml vs(660?111)ml,t=17.173,P=0.000],and required less blood transfusion [(270?77)ml vs(510?144)ml,t=17.861,P=0.000] than the on-pump group.In the off-pump group,3(2.0%)of the 150 patients developed renal function injury that is significantly more than that in the on-pump group [11/140(7.9%),?2=5.407,P=0.020].Conclusions Off-pump CABG is as effective as the on-pump surgery;moreover,it is a better choice for patients with high-risk coronary disease since this technique is superior in reducing respiratory support time,volumes of chest drainage and blood transfusion,and renal function injury.

Objective Puerarin can remove inflammatory mediators, but the underlying mechanisms are not yet clear.The purpose of this study is to observe the synthesis of IL-6 in co-cultured bronchial epithelial (Beas-2B) and neutrophil cells, and to investigate the inhibitory effect of puerarin on IL-6.Methods Beas-2B and neutrophil cells were extracted and divided into six groups: neutrophil cells cultured alone (NC), Beas-2B cells cultured alone (BC), Beas-2B and neutrophil cells co-cultured (BC+NC), and Beas-2B and neutrophil cells co-cultured with puerarin at 50 μg/mL (BC+NC+P50), 100 μg/mL (BC+NC+P100) and 200 μg/mL (BC+NC+P200).The concentrations of IL-6 in different groups were quantitatively measured by ELISA and the expression of the IL-6 gene detected by real-time PCR.Results After 18 hours of culturing, the concentration of IL-6 was significantly increased in the BC+NC group ([280.409±21.340] pg/mL) as compared with those in BC ([240.002±23.727] pg/mL), NC ([22.771±1.146] pg/mL), BC+NC+P50 ([244.205±9.335] pg/mL), BC+NC+P100 ([218.168±18.635] pg/mL), and BC+NC+P200 ([179.539±7.340] pg/mL) (P<0.05), but lower in the BC+NC+P200 than in the BC+NC+P50 and BC+NC+P100 groups (P<0.05).The expression of the IL-6 gene was markedly up-regulated in the BC+NC group (1.515±0.013) in comparison with those in BC (1.000±0.215), BC+NC+P50 (0.398±0.024), BC+NC+P100 (0.332±0.016), and BC+NC+P200 (0.306±0.015) (P<0.05), but lower in the BC+NC+P200 than in the BC and BC+NC+P50 groups (P<0.05).Conclusion Direct-contact co-culture of Beas-2B and neutrophil cells significantly enhances the synthesis and release of the inflammatory mediator IL-6, which can be inhibited by puerarin.

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.

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.
