Objective To explore the wound healing of semi-toe nail flap donor site after transplantation. Methods To repair small wounds,on 13 toes the first metatarsal dorsal flaps were applied,and on 7 toes the second toe digital flaps were applied.While,to repair large wounds,free flaps were applied,including foot inside flaps on 3 toes,peroneal artery perforator flaps on 5 toes,tarsal lateral artery flaps on 2 toes,and phil bowel artery inside branch flaps on 3 toes.Wounds remaining on semi-toe nail flaps of 7 toes were all covered with fibular island flaps of the first toes. Results Twenty cases were followed up,and the rang between 6 months to 5 years.The nail margin was exposed out of the lateral flaps in 2 cases.The first toes and the second toes appeared nearly normal in the other 18 cases.The flaps appeared smooth,flexible appearance with nice color and no ulceration.Seven cases applied with free flaps recovered protective sensibility with no complaint. Conclusion To cover wounds on semi-toe nail flaps of the first toes and the second toes with flaps is an ideal treatment method.The method of free flap transplantation is superior to vascular pedicle flap graft.

Objective We discussed the nursing of patients with superior mesenteric artery syndrome (SMAS) through duodenal circular drainage operation. Methods We carried out a retrospective analysis for 42 SMAS patients undergoing duodenal circular drainage operation from. 1959 to 2007. They were given preoperative psychological nursing, correct lying style, postoperative nutritional support and health education instruction. The treatment effect was observed. Results All patients cured and left hospital. The treatment effect was good after one to fifteen years of follow-up visit. Five patients who changed to adopt duodenal circular drainage operation also got good result after nine to ten years of follow-up visit. The incidence of anastomotic ulcer and anastomotic stenosis as well as reflux gastritis was not seen. Conclusion SMAS could be cured earlier through duodenal circular drainage operation and effective nursing.

The peroneal artery chimeric bone flap combined with chimeric flap of lateral femoral circumflex artery was applied in the repair of a case defects of both ulna and radius arteries combined with large extensive ring-like soft tissue defects of forearm in November, 2018, causing no blood supply to the hand. In the one-stage surgical procedure, anastomosis of the ulnar and radial arteries with the pedicle of the 2 flaps by Flow-through anastomosis were performed and the blood supply of the forearm and hand was restored. Six months after the surgery, the rotation functions of forearm, wrist joint and fingers were recovered. The patient was able to carry out daily activities and some of precision tasks.

Objective To evaluate the feasibility and clinical efficacy of lateral femoral circumflex artery perforator flaps and fit together in the treatment of limbs complex wound surface.Methods From January 2010 to March 2012,use the characteristics that the descending branch of lateral femoral circumflex artery extend its branches over the flap,fascia and skin,to form lenticulostriate arteries,which contain 2 to 3 different species tissues fits together,flaps cover the important tissues such as vessel,nerves and bones.Fascia covers the tendinous tissues etc.Muscle can not only cover the tissues,but also fill in the space,and followed by skin grafting.This research was to perform the treatment for 4 cases of lacking limbs ring tissue,three cases of multiple wound surface,six cases of hand avulsion injury of skin and 9 cases of Gustilo grade-Ⅲ C.Results As for the 22 cases in the research,nineteen cases of flaps survived,the other 3 cases were necrosis with length of 1cm to 2 cm at distal and self-healed later.During 6 months to 2 years followed-up of 18 cases,external flaps were satisfactory,skin grafting over the fascia layers develops very well,smooth with great elasticity,no recoil,and no color change.Conclusion Lateral femoral circumflex artery is one of effective restoration methods for limbs with complex wound surface.

From the Chinese medicine point of view on the physiological functions of healthy atmosphere and vitality, healthy atmosphere and vitality of the relationship, we can know that healthy atmosphere and vitality has important role in the life activities of the body. They complement each other. In the pathogenesis of AIDS, AIDS epidemic poi-son has the characteristics of wounding healthy atmosphere. When it attacks the body upright, vitality will be injured firstly. Because of that it is inextricably linked with the characteristics of the AIDS epidemic poison and vitality physiological functions. Therefore, AIDS epidemic poison attacks healthy atmosphere and vitality co-exist, the injury of healthy atmosphere and vitality is throughout the whole process of AIDS .

Objective To investigate the effect of vascularized fibula with fibular flap to repair limb bones and soft tissue defects.Methods Transpositional fibulas were used to repair tibiae defects in 4 cases.Free fibular transplantation was used in 6 cases,including folded fibular transplantation in 3 cases distal femur repair in 2 cases,calcaneus repair in I case.Hole fibular transplantation was used in 11 cases to repair tibia radius and metatarsal bones.Semi-fibular transplantation was used to repair metacarpal bone defects in 2 cases.All transplanted bones were together with the flap to repair bones and soft tissue defects.Results Twenty cases were all survived,with bone healing time of 6 to 10 weeks,and weight bearing time of 3 to 6 months,fifteen cases were followed up for 6 months to 4 years,and the results showed that their transplanted bones became thicker,their lower limbs recovered to normal walking,hand grip function recovered,the transplanted flaps were elastic.Conclusion Vascularized fibula and fibular flaps transplantation was an effective way to repair limb bones and soft tissue defects.

Objective To investigate the methods to cover the donor site of wrap around flap from toe. Methods In 34 cases, 8 thumbs reconstructed with wrap around flap from great toe, 8 thumbs and 14 fingers reconstructed with half nail flap from fibular side of second toe, and 4 fingers reconstructed with dorsal nail flap from second toe. The donor site were covered with pedicle flap (first metatarsal dorsal flap, second toe digital flap, neighbor flap from dorsal of second toe, and lateral tarsus flap) or free flap (medical plantar flap, fibular artery flap, and lateral tarsus flap). Results Twelve cases were followed up after 2 months, normal gait were found, 6 cases were followed up after 4 months, (4 cases for first metatarsal dorsal flap, one for fibular artery flap and one for internal volar flap). 2 cases recovered defend sensibility and showed a bit dark, the cases which reconstructed with medical plantar flap and second toe digital flap had nearly normal sensibility. The outward appearance of the donor site were chubbiness, flexible, and no complaint were found. Conclusion Covered the donor site of wrap around flap from toe with these flaps can avoid complications like pain and ulcerate, and have a satisfactory appearance.

Objective To improve the outward appearanee in toe-to-hand transfer,a reshaped procedure of second toe was studied. Methods In reconstructing a finger with second toe transfer,a piece of flap from the fibular side of the second toe,or/and a H-shaped flap from the tibial of great toe were designed and transferred to the volar side in order to obliterate the constriction below the toe pulp. Results In 17 patients,22 fingers reconstructed with these procedure,ouly one rotation flap necrosis partly.The appearance of the newly reconstructed thumbs and fingers were improved,the pulp of reconstructed finger was similar to a natural finger, the narrow neck of second toe was well-stacked,and the interpbalangeal joint was straighten. Conclusion Reconstructed finger with this reshaped second toe is similar to a normal finger.

Objective To study the degradation of hepatitis C virus(HCV) genome before and after methylene blue photochemistry(MB-P) treatment of the plasma.Methods MB was added to HCV positive plasma to a final concentration of 1.0?mol/L.The plasma was then exposed to 30000 Lux fluorescence.Plasma samples were then collected at different times of exposure.Real-time PCR was used to quantitatively study the course of the HCV-RNA degradation.The whole genome was screened for integrity by RT-PCR with 8 pairs of specific primers which targeted sequential overlapping sections of HCV genome.Results Results of real-time PCR showed that the copy number of HCV-RNA was continuously decreasing during MB-P treatment.RT-PCR results showed that the reactivity of different sections of the HCV genome to MB-P was significantly different and indicated that the 5' end and 3' end were more stable. Conclusion MB-P treatment could degrade HCV RNA with various sensitivities to different sections of the genome.RNA degradation may play an important role in plasma virus inactivation.Detection of HCV genomic RNA might be clinically useful to monitor the process and efficiency of virus inactivation.
