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]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.

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 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.

Objective To evaluate the clinical features,pathological grades,treatment and prognosis in bladder cancer patients under 40 years.Methods A retrospective review of transitional cell carcinoma of the bladder in patients under 40 years who had been treated from January 1994 to April 2005 were conduc- ted.The patients were divided into 2 groups(group A,20-30 years;group B,31-40 years)based on their age.The differences in pathologic grading,recurrence rate and positive rate of urine cytology were compared between the 2 groups.The statistical analyses were performed using x~2 test.Results The incidence of bladder cancer in patients under 40 years was 4.2%(92/2200).The male/female ratio was 2.7:1.0.At initial visit,86%(68.7% in group A and 91.1% in group B)of the patients presented with gross hematuri- a;and 25.0% in group A and 33.9% in group B concomitantly had frequency and dysuria.The mean disease course in the 2 groups was 3.8 months for male and 6.9 months for female.Solitary tumor occurred in 19 ca- ses(100.0%)in group A and 63(86.3%)in group B;and multiple carcinomas,in 10 cases(13.7%)in group B.All were superficial bladder cancers in group A,while 6(8.2%)were invasive carcinomas in group B.According to WHO pathological grading of bladder cancer,in group A,10 cases(52.6%)had G_1,8 (42.1%)had G_2 and 1(5.3%)had G_3 tumors;in group B,8 cases(11.0%)had G_1,49(67.1%)had G_2 and 16(21.9%)had G_3 tumors(P＜0.01).The positive rate of urine cytology was 53.3% in all 92 ca- ses(25.0% in group A and 60.7% in group B,P＜0.05).The diagnostic rates by B-ultrasound and cysto- scopy were 98.6% and 100.0%,respectively.Of the 92 patients,11(12.0%)were treated by partial cys- tectomy,73(79.3%)by TUR-Bt and 8(8.7%)by cystectomy.The follow-up was 3-115 months(mean, 39 months).The overall recurrence rate was 12.0%,with 5.3%(1/19)in group A and 13.7%(10/73)in group B.Of 10 patients with multiple carcinomas,6(60.0%)developed recurrence;and of 82 with solitary tumors,5(6.1%)developed recurrence,with significant difference between them(P＜0.01).Two of the multiple carcinoma patients developed invasive carcinoma.Conclusions In bladder cancer patients under 40 years,the positive rate of urine cytology,pathological grading and recurrence rate increase with age.Multi- ple tumors,invasive carcinoma and long-term smoking are high risk factors for tumor recurrence.TURBt is the main surgical method for treating bladder cancer patients under 40 years.
