Objective:To explore the clinical efficacy of the first dorsal metatarsal artery pedicled lateral toe bilobed flap in repairing the finger pulp defects of two adjacent fingers.Methods:This study was a retrospective observational study. From January 2018 to December 2022, 9 patients with finger pulp defects in two adjacent fingers who met the inclusion criteria were admitted to the Department of Burns and Plastic Surgery of the 988 th Hospital of Joint Logistics Support Force of PLA, including 6 males and 3 females, aged 26 to 48 years. The injured fingers were the index finger and middle finger (5 cases) or the middle finger and ring finger (4 cases). After debridement, the wound area of a single finger ranged from 1.2 cm×0.8 cm to 3.2 cm×2.8 cm. The finger pulp defects of two adjacent fingers were repaired with the first dorsal metatarsal artery pedicled lateral toe bilobed flap, and the two adjacent fingers were sutured together. The area of single flap ranged from 1.5 cm×1.0 cm to 3.5 cm×3.0 cm. The wound in the flap donor site was sutured directly or repaired with full-thickness skin graft from the groin region. The finger separation surgery was performed 3 weeks after surgery. The survival and blood supply of flaps, and survival of skin grafts and wound healing of the donor sites were observed after surgery. During follow-up, the texture, sliding, and shape of the flap, movement function of the finger, and the shape and function of the foot donor site were observed. At the last follow-up, the sensory of the flap was evaluated according to the sensory evaluation standard of the British Medical Research Council, and the hand function was evaluated according to the functional evaluation trial standard for severed finger replantation of the Hand Surgery Society of the Chinese Medical Association. Results:After surgery, all the flaps of 9 patients survived without vascular crisis. The flaps were soft in texture and good in shape. One patient had partial necrosis at the edge of the skin graft in the toe, and the wound healed after dressing change; the skin grafts in the toe in the other 8 patients survived, and the wounds healed well. During follow-up of 12 to 18 months after surgery, the flaps had soft texture, good elasticity, low sliding, and good shape. The finger movement function was normal. The wound in foot donor site recovered well without ulceration and deformity, and walking was not affected. At the last follow-up, the sensation of the flaps was sensitive, of which 8 flaps reached S3 and 10 flaps reached S3 + in sensation, and the two-point discrimination distance of the flaps was 9-13 mm. The functional scores of the affected fingers were 85 to 95, all of which were excellent. Conclusions:The first dorsal metatarsal artery pedicled lateral toe bilobed flap can repair finger pulp defects of two adjacent fingers at the same time, and the appearance, sensation, and function of the affected fingers recovered well after surgery, with less damage to the foot donor site. It is one of good methods to repair finger pulp defects of two adjacent fingers in clinic.

Objective:To explore the clinical effects of parallel combined flow-through perforator flaps in the treatment of circular hot crush injuries in limbs with blood supply disorder.Methods:The study was a retrospective observational study. From April 2016 to December 2022, 4 cases with circular hot crush injuries in limbs with blood supply disorder were admitted to the Department of Burns and Plastic Surgery of the 988 th Hospital of Joint Logistics Support Force of PLA, including 3 males and 1 female, aged from 24 to 48 years. Among them, 2 cases were injured in the calf and 2 cases were injured in the forearm. After emergency debridement, the area of skin and soft tissue defects was from 20 cm×20 cm to 44 cm×20 cm. The patients had defects in tibialis anterior and posterior tibial arteries with a length of 13 to 18 cm, and in ulnar and radial arteries with a length of 9 to 12 cm. Flaps were designed and cut, including a flow-through anterolateral thigh perforator flap with area of 20 cm×9 cm to 24 cm×21 cm carrying the descending branch of the lateral circumflex femoral artery and the accompanying veins of 8 to 18 cm in length; and a flow-through posterior tibial artery perforator flap with area of 21 cm×13 cm and 20 cm×14 cm carrying the posterior tibial artery, the accompanying veins with a length of 14 and 17 cm respectively, and the great saphenous vein with a length of 22 and 21 cm. The circular hot crush injury wounds in the calf with blood supply disorder were repaired by a parallel combination of flow-through posterior tibial artery perforator flap and flow-through anterolateral thigh perforator flap, and the circular hot crush injury wounds in the forearm with blood supply disorder were repaired by a parallel combination of bilateral flow-through anterolateral thigh perforator flap, and the injured main vessels were reconstructed. The donor site wounds of flap were closed directly or treated with split-thickness skin grafts from abdomen. After surgery, the blood supply and survival of the flap and distal affected limb, the healing of wounds in the donor and recipient sites, the survival of the skin graft in the flap donor site were observed. During follow-up, the condition of flaps, the appearance, blood supply, and function of affected limbs were observed. At the last follow-up, the foot and ankle functions were evaluated according to the scoring standards of American Orthopedic Foot and Ankle Association, and the wrist and hand function was evaluated according to the trial standard of replantation of amputated upper limb function assessment of the Hand Surgery of Chinese Medical Association. Results:The flaps and distal affected limbs of 4 patients had good blood circulation and successfully survived after surgery. The wounds of 3 cases successfully healed, while one patient with circular hot crush injury in the forearm experienced exudation in the recipient site in the later stage, and the wound healed after re-expansion and suturing. The donor site wounds healed smoothly, and the skin grafts successfully survived. During follow-up of 12 to 24 months after surgery, the flaps were slightly swollen, the limbs had good appearance, normal blood circulation, and fine functional recovery. At the last follow-up, the foot and ankle function of 2 patients with circular hot crush injuries in the calf was evaluated as good in 1 case and commonly in 1 case; the wrist and hand function of 2 patients with circular hot crush injuries in the forearm was evaluated as excellent in 1 case and good in 1 case.Conclusions:The parallel combined flow-through perforator flap can reconstruct the damaged main blood vessels and repair the wound at the same time. It can not only effectively save the limb, but also restore part of the function of the affected limb. It is one of the effective methods to treat the circular hot crush injuries in limbs with blood supply disorder.

A set of L-band electron spin resonance imaging (ESRI) equipment suitable for biological species was developed and an ESRI experiment model for viable skin samples was established. The mechanic process of nitroxide free radical TEMPO (2,2, 6, 6-tetramethyl-1-piperidinyloxy) penetrating through skin sample and the spin density distribution of TEMPO after it interacted with skin sample were detected by the developed ESRI method. Skin samples were extracted from mice back. The experimental samples were prepared by cutting the skin pieces into square shape of 2 x 2 cm2 and then the samples were divided into three groups by treating them with three different methods: Method A, simple treatment by simply cutting the hair; method B, 8% Na2S depilation treatment for 10 min; method C, 8% Na2S depilation and then 5% pancreatic digestion treatment for 2 hours. The liposoluble solvent DMSO (dimethyl sulfoxide) and distilled water were used as two kinds of solvent for the TEMPO liquor. The results indicated that the skin-penetration properties of TEMPO were significantly different among samples treated with different methods and the surface cornifin of skin offered remarkable resistance to TEMPO. The TEMPO liquor of water could hardly penetrate through skins, whereas about 20%-30% of the original TEMPO compounds that solved in liposoluble solvent DMSO could penetrate through the skin sample treated with method C after 16 hours of interaction. Furthermore, the penetration rate of TEMPO through the skin tissue was a strong time dependent process. The preliminary application results suggested that ESRI technique could provide an effective and applicable method for dynamically researching skin-penetration properties of some special kinds of materials such as paramagnetic compounds.

Quality evaluations of reports were conducted from 5 aspects including 25 items. 5 aspects were all considered in 13 studies. 60% of the 25 items were in- volved in 13 reports at least and 88% at most. CONCLUSION:Meta- analysis methods are improved significantly in China. It should be still standardized to make sure correctness and reliability of results of meta-analysis. Meta-analysis method should be stan-dardized to obtain correct and reliable results.

In order to investigate the maxillary preprosthetic situation after oral tumor treatment and/or reconstructive surgery, based on the review of case history and the clinical records 47 cases were analyzed after oral tumor treatment and/or reconstruction, including residual maxillary bone, intermaxillary relationships, defection of maxilla and oral situation after radiation therapy. The results showed that the residual maxillary bone was useful for implantation in the front alveolar bone and zygoma area. The maxillary preprosthetic situation after tumor treatment and/or reconstructive surgery was difficult due to maxillary resection, intermaxillary relationships, unsuitable soft and hard tissue transfer and the irradiation. It is suggested that the maxillary preprosthetic situation after oral tumor treatment is getting worse not only due to maxillary resection and/or irradiation, but surprisingly also due to mandibular resection and/or irradiation.
