Objective To investigate the clinical application of neighboring digital artery flow-through flaps for one-staged skin coverage and revascularisation after severe finger injuries.Methods From May 2008 to July 2010,there were ischemic fingers had severe injuries,aged 19 to 52 years old,which were male in 5 cases,female in 2 cases,with skin and arterier defected.One-staged coverage and revascularisation of traumatised fingers were used with neighboring digital artery flow-through flaps.Functional exercise and physical therapy were done 3 weeks later.All cases had more than 12 months' fellowed-up periods.The sensibility testing,Questionnaire of the flap aesthetic satisfactory and TAM evaluations were all performed in all patients.All the results were measured and evaluated.Results All flaps survived completely and digit blood circulations were good in 7 patients.The flaps had good appearance and aesthetic satisfactory (100％).At 12 months after operations,the pain and touch perception reinnervated until 6 months and two-point discrimination testing were 6.1 to 9.6 mm,mean was (7.1 ± 1.3) mm,and the flap sensibility assessment were S3 * and TAM evaluation ratio were 0.81 ±0.16.Conclution Neighboring digital artery flap ideally suited as a thin and pliable flow-through flap in digital replantation/revascularization.It is helpful for salvage of the ischemic fingers after injury with skin and arteries defects.

Objective To investigate the effect and recurrence of the esomeprazole combined with trimebutine on treatment for non-erosive reflux disease(NERD).Methods One hundred and twenty-five cases of patients with NERD were randomly divided into the treatment group (n =62) and the control group (n =63).Patients in treatment group were received the esomeprazole 20 mg,twice a day and trimebutine 0.2 g,3 times a day,in control group were received the esomeprazole 20 mg,twice a day and mosapride 5 mg,3 times a day.After 8 weeks treatment,6 months follow-up was conducted and the effects and recurrence were evaluated.Results The clinical curative rates at 4th and 8th weeks treatment in treatment group were 75.8％ (47/62) and 95.2％ (59/62),higher than that of control group (57.1％ (36/63),x2 =4.879,P =0.027 ; 84.1％ (53/63),x2 =4.083,P =0.043).The GERDQ curative rates at 4th and 8th weeks treatment in treatment group were 72.6％ (45/62),93.5％ (58/62) respectively,significantly higher than that of the control group (52.4％ (33/ 63),x2 =5.434,P =0.020 ; 79.4％ (50/63),x2 =5.350,P =0.021).The recurrence rates of 6 months followup were 77.4％ (48/62) in the treatment group and 81.0％ (51/63) in the control group,there was no significant difference between the two groups (P =0.627).Conclusion Esomeprazole combined with trimebutine is safe and effective treatment on non-erosive reflux disease,and the recurrence rates was lower than that in the control group.

Objective To investigate the effect of propofol on ketamine-induced cognitive dysfunction and neuronal apoptosis in hippocampus in aged rats. Methods Thirty-two male SD rats aged 18-24 months weighing 380-470 g were randomly divided into 4 groups ( n = 8 each) :control group (group C);propofol group (group P);ketamine group (group K) and propofol + ketamine group (group PK). Propofol 30 mg·kg-1·h-1 or/and ketamine 40 mg· kg-1·h-1 were infused for 2 h once a day for 7 consecutive days. After the last day of drug administration cognitive function was assessed using Morris water maze (escape latency and the number of animals' swimming across the platform). The animals were sncrificed after water naze test and their hippocampi were removed for determination of neuronal apoptosis (by TUNEL) and caspase-3 expression (by immuno-histochemistry) in hippocampal CA1 region. Results There was no significant difference in escape latency and the number of the animals,swimming across the platform, the neuronal apoptotic rate (the number of apoptotic neurons/the number of total neurons) and caspase-3 expression between group C and P. In group K and PK the escape latency was prolonged,the number of animals' swimming across the platform was decreased, neuronal apoptotic rate increased and the caspase-3 expression up-regulated as compared with group C. The ketamine-induced changes were significantly attenuated by coadministration of propofol in group PK. Conclusion Coadministration of propofol can ameliorate ketamine-induced cognitive dysfunction and hippocampal neuronal apoptosis.

Objective To prospectively compare the clinical efficacy between high versus low viscosity bone cement in percutaneous vertebroplasty (PVP) for severe osteoporotic vertebral compression fractures (OVCF).Methods A prospective study was conducted in 61 old patients with single severe OVCF who had sought medical attention in our hospital from August 2014 to October 2015.They were randomly assigned to group H (n =30) to receive PVP using high viscosity bone cement and group L (n =31) to receive PVP using low viscosity bone cement.The 2 groups were compared preoperatively and postoperatively in terms of visual analogue scale (VAS),Oswestry disability index(ODI),short Form-36 General Health Survey(SF-36),Kyphosis cobb's angle,height of the injured vertebra,and volume and leakage of bone cement.Results Significant improvements in VAS,ODI and SF-36 score were noted after operation in both groups,but there were no significant differences between the 2 groups (P ＞ 0.05).The 2 groups made significant improvements after operation in cobb's angle and height recovery rate of the injured vertebra;improvements in group H (14.7° ± 3.4° and 28％ ± 8％) were significantly greater than in group L (16.5° ± 2.5° and 22％ ± 7％) (P ＜ 0.05).The bone cement volumes in groups H and L were 4.94 ± 0.72 mL and 4.89 ±0.75 mL respectively,showing no statistically significant difference between the 2 groups (P ＞ 0.05).The leakage rate in group H was significantly lower than that in group L (13.33％ versus 35.48％) (P ＜ 0.05).All the patients were followed up for a mean time of 12 months (range,from 3 to 17 months).Cauda equina symptoms were observed in one patient and compression fracture of the adjacent vertebra happened in 2 patients,but no infection or pulmonary embolism occurred in any patient.Conclusions Both high viscosity cement PVP and low viscosity cement PVP can relieve back pain and improve quality of life in patients with severe OVCF,but the former may increase the efficacy and safety of PVP obviously in correction of cobb's angle,height restoration of the injured vertebra and reduction of cement leakage.

OBJECTIVETo investigate the clinical effect of anastomosis of superficial veins for improving the drainage of perforator propeller flaps.

METHODSFrom Sept. 2011 to Dec. 2012, 11 cases with soft tissue defects and chronic ulcer wound at extremities were treated with adjacent perforator propeller flaps, which were pedicled by the peroneal artery(5 cases), or the lateral supramalleolar artery(3 cases), or the ulnar artery (2 cases), or the posterior interrosseous artery (1 case). The wound size ranged from from 3.0 cm x 2. 5 cm to 11. 0 cm x 4. 0 cm, and the falps size ranged from 6 cm x 3 cm to 21 em x 5 cm. One superficial vein in all the flaps was anastomosed with superficial vein in the recipient area. The blood supply of the flaps were recorded after operation 1 - 3 months after operation, the fluency of anastomosed vein was detected by color Doppler ultrasound. Flap swelling evaluations were performed in early 3 months and later 3 - 6 months, and the results were classified into 4 grading degrees. 6 months later, Questionnaire of the flap aesthetic satisfactory was performed for seven patients during follow-up period.

RESULTS9 flaps survived completely, two flaps had partial marginal skin necrosis in the distal end, which were both managed with surgical debridement, and both wounds healed in two months. 9 cases were followed up for more than 12 - 19 months. The early rsults of flap swelling evaluations were: I degree 0 case, II degree 8 cases, III degree 3 cases, IV degree 0 case, and the later results were: I degree 7 cases, II degree 4 cases, III degree 0 case, IV degree 0 case. The flaps had ideal appearance, good contour, and high aesthetic satisfactory (100%). The mean flap survival area rate of veins anastomosed was (98. 6 ± 9. 7) %.

CONCLUSIONSPerforator propeller flaps with anastomosis of superficial veins can improve the flap venous drainage, avoid transient venous venous congestion, so as to increase the flap survival. It is an effective way for improving the vein drainage.

OBJECTIVETo investigate the clinical application of flow-through deep inferior epigastric perforator flaps for reconstruction of large defects at the extremities.

METHODSThe deep inferior and superior epigastric arteries were designed as the axial vessel and the arterial supply to the flap was the paraumbilical perforator artery. Free deep inferior epigastric perforator flaps were harvested in flow- through manners to reconstruct associated arterial defect in the wound. The sensation assessment,Enneking score,and questionnaire of the flap aesthetic were all performed during follow-up period.

RESULTSFrom December 2011 to September 2012, 5 patients with large defects at extremities were treated. The deep inferior and superior epigastric arteries were designed as the axial vessel and the arterial supply to the flap was the paraumbilical perforator artery. The wound defects ranged form 11 cm x 5 cm to 30 cm x 11 cm. And the flap size ranged from 13 cm x7 cm to 33 cm x 13 cm. All flaps survived completely. The recipient arteries were all bypassed well documented by color Doppler examinations. All cases had 12-24 months' follow-up period. The flaps had good appearance and high aesthetic satisfactory(100%). 12 months after operations, sensation assessment were all S3+, and the Enneking score ratios were 82%-95% ,with 87.2% in average.

CONCLUSIONSFlow-through deep inferior epigastric perforator flaps are reliable and effective for reconstruction of large defects at the extremities with maintenance of the vascular status of the extremities. The flaps can also be designed in transverse or oblique mode for clinical application.
