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: Hereditary susceptibility is an important role in episode and development of diabetic nephropathy (DN). Aggregation of monocyte in kidney tissue, differentiation to histocyte and reinforcement of signal are possibly closed to episode and development of DN in type 2 diabetes mellitus (DM). Regulated upon activation normal T-cell expressed and secreted (RANTES) is a chemokine of C-C subtribe. It can mediate infiltration and activation of inflammatory cells and cause injuries of renal corpuscle and renal mesenchymal. This may be a key mechanism of episode and development of DM. Thus, RANTES gene may be one of the susceptible gene of DN. OBJECTIVE :To investigate correlation between RANTES gene promoter -28C/G polymorphism and DN in type 2 DM in Chinese. DESIGN: Case-contrast study. SETTING: Department of Endocrine, Affiliated Hospital of Guiyang Medical College; Center of Diabetes Mellitus of Guizhou Province. PARTICIPANTS: A total of 143 patients with type 2 DM were recruited from the Department of Endocrine, Affiliated Hospital of Guiyang Medical College and Department of Endocrine,Guizhou People's Hospital from September 2003 to September 2005. Among them, 53 cases had normoalbuminuria, 54 microalbuminuria and 36 macroalbuminuria. Another 55 healthy subjects who were selected from Center of Health Examination, Affiliated Hospital of Guiyang Medical College were regarded as control group. METHODS: 3-5 mL peripheral venous blood was collected from all subjects. RANTES gene promoter -28C/G genotype was detected with polymerase chain reaction restriction fragment length polymorphism technique. MAIN OUTCOME MEASURES: ① Allele frequency and genotypic frequency of RANTES gene promoter -28C/G; ② risk factor of DN was analyzed with Logistic regression analysis. RESULTS: All 198 subjects were involved in the final analysis. ① Comparison of CG genotypic frequency of -28C/G: There was no significant difference between normal control group and DM group (P＞ 0.05); however, that in microalbuminuria group and macroalbuminuria group was higher than that in normoalbuminuria group (24.1％, 47.2％, 9.4％, P ＜ 0.05), and that in macroalbuminuria group was also higher than that in microalbuminuria group (P ＜ 0.05). ② Frequency of G allele of -28C/G: There was no significant difference between normal control group and DM group (P ＞ 0.05); however, that in micro albuminuria group and macrealbuminuria group was higher than that in microalbuminuria group (12.0％, 23.6％, 4.7％, P ＜ 0.05), and that in macroalbuminuria group was also higher than that in microalbuminuria group (P＜ 0.05). ③ Logistic regression analysis showed that positive genotype of -28G was related to DN (95％ Cl:1.402-15.032, P =0.012). CONCLUSION: Positive genotype of RANTES gene promoter-28G may be related to DN.

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 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.

AIM: To observe the efficacy of intravitreal injection with ranibizumab combined with laser photocoagulation for macular edema ( ME ) secondary to macular branch retinal vein occlusion( MBRVO) .
METHODS:A retrospective analysis included 33 patients (33 eyes) with ME secondary to MBRVO were taken. All patients received intravitreal injection of 0. 5mg ranibizumab ( 0. 05ml ) at first visit. The continue PRN treatment and laser photocoagulation were based on the visual acuity changes and optical coherence tomography findings. The changes of best corrected visual acuity ( BCVA) , central macular thickness( CMT) , and amplitude density and latency of P1 wave in mfERG were observed before treatment and 6mo after treatment.
RESULTS: Before the treatment, logMAR was 0. 68±0.35, 6mo after treatment was 0. 34±0. 23, BCVA was improved obviously ( P < 0. 01 ), BCVA in 21 patients ( 63.64%) were improved in two rows among all the patients. CMT before treatment was(487. 30±63. 58) μm, after treatment was(238. 84±52. 66) μm(P<0. 01). The amplitude densities of P1 wave in ring 1, ring 2 and ring 3 after treatment were significantly increased(all P<0. 01), and the latencies were decrease ( all P < 0. 05 ). The conjunctival hemorrhage was observed in 2 eyes after treatment.
CONCLUSION: Intravitreal injection with ranibizumab combined with laser photocoagulation for ME secondary to MBRVO can reduce the CMT and improve visual function.
