Objective To study the methods and therapeutic effect of coverage the soft tissue defect in the foot and ankle with neurocutaneous sural artery island flap.Methods 30 patients had been reconstructed foot and ankle soft-tissue defects with neurocutaneous sural artery island flap,the area of soft tissue defect from 2.0 cm × 3.5 cm~ 8.0 cm× 16.5 cm,the flaps were designed with the size measuring 2.5 cm × 4.0 cm to 8.5 cm × 18cm.Results 26 flaps survived completely and 4 with partial or margin necrosis,the wound infection occurred in 6 patients and were treated with dressing,shin graft and antibiotic drug.Conclusions Sural neurocutaneous island flaps are easy to separate.Major arteries are not injured.It is the ideal flap to repair the soft tissue defect around ankle and foot,the texture,color and contour of the flap is similar to recipient area.

Objective To explore the feasibility of tibial nerve motor branches transfer to the deep fibular nerve in an anatomical study.Methods Twenty-three sides lower limbs from 12 adult cadavers which preserved in Formalin were used for dissection of the tibial nerve and its all motor branches,and the proximal deep and superficial fibular nerve.Experimental measurement were performed for the parameters of each branch such as length,diameter,the location of original point relative to the level of the fibular head.The diameter of proximal part of the deep fibular nerve was measured simultaneously.Finally,the length from original point of each branch to the fibular neck was also measured during simulation of nerve transfer procedure.Results The average length of motor branches to the flexor digitorum longus muscle,to the flexor hallucis longus muscle and the superficial branches to the soleus muscle were (95.70 ± 13.40)mm,(96.90± 13.60)mm and (73.60 ± 12.00)mm respectively.Their average diameter were (0.63 ± 0.16)mm,(0.65 ±0.20)mm and ( 1.56 ± 0.26)mm respectively.The average diameter of proximal deep fibular nerve was (2.54± 0.26)mm.Based on length,branches to the flexor digitorum longus muscle and flexor hallucis longus muscle were adequate for direct nerve transfer to the deep fibular nerve in all specimens without interpositional grafr.And in 22 specimens (95.7 percent),the superficial branches to the soleus muscle were long enough to directly transfer.Other branches of the tibial nerve were not adequate for direct nerve transfer Conclusion This study confirmed the anatomical feasibility of using motor branches from tibial nerve for direct transfer to restore the deep fibular nerve.The superficial branches to soleus muscle were the best donor nerve if considering the branches,length,diameter and the difficulty of surgical procedures.

Objective To investigate the therapeutic effect of kansui root on patients with severe acute pancreatitis(SAP). Methods Clinical data of 54 cases of severe acute pancreatitis treated with kansui root(kansui root group) were analyzed and compared with 54 cases of severe acute pancreatitis treated without kansui root (control group).Results The releivng time of abdominal pain was significantly shorter than that in control group( P

Objective:To observe the effect of well-designed board sanding training on the upper extremity motor functioning of hemiplegic stroke survivors.Methods:Sixty stroke survivors with hemiplegia were randomly divided into an observation group (30 cases) and a control group (30 cases). All received conventional rehabilitation. The observation group′s training involved intelligent board sanding, while the control group′s training involved traditional sanding.Results:After the treatment, significant improvement was observed in the Fugl-Meyer upper extremity scores, modified Barthel index scores and reported shoulder pain in both groups, with the observation group′s averages significantly better than those of the control group. After the intervention, the average scores of both groups on the modified Ashforth scale had also improved significantly.Conclusions:Supplementing conventional rehabilitation treatment with intelligent board sanding can significantly improve upper extremity motor function and ability in the activities of daily living of stroke survivors with hemiplegia while somewhat relieving shoulder pain. The effect is better than with traditional board sanding.

OBJECTIVETo investigate the feasibility of extraction site preservation using injectable calcium phosphate cement (CPC) combine with poly (lactic-co-glycolic acid) (PLGA) microspheres.
METHODSImmediate extraction defects models were created in canine mandibles, and the defects were filled with CPC/PLGA (experimental group, E) , Bio-Oss (positive control, P), non-treatment (blank control, B) respectively. Dogs were sacrificed after 4, 8, 12 weeks post operation. Statistical analysis were conducted using SPSS 19.
RESULTS RESULTSof radiological observation showed that there were not significantly different between groups in 4 and 8 week (P > 0.05). After 12 week,E (114.9 ± 8.4) were not significantly different compared with P (117.4 ± 12.1) (P > 0.05) , both were significantly higher than B (95.0 ± 12.6) (P < 0.05) . Histology examination showed that at 4 week following surgery, the result of newly formed bone was as follow, P[ (87.5 ± 1.5) %] > B[(78.7 ± 2.7)%] > E[(69.2 ± 1.8)%] (P < 0.05). At 8, 12 week, results of P[(94.0 ± 2.3)% and (93.5 ± 1.9) %] and E[ (94.7 ± 1.1) % and (96.0 ± 0.9) %] were better than those of B[ (76.8 ± 3.0)% and (87.0 ± 2.4)%] (P < 0.05).
CONCLUSIONSThe effect of CPC/PLGA repair immediate alveolar ridge defects is the same as that of Bio-Oss, and CPC/PLGA can be used as a material in extraction site preservation.
