Objective To report the anatomical study and clinical application of the free peroneal perforator-based sural neurofasciocutaneous flap. Methods Latex injection studies were performed on 10 adult cadaveric lower limbs. The presence, prevalence, and location of the peronel perforators that were suitable for vascular anastomosis were documented. From April 2007 to January 2010, 6 patients with large soft tissue defects in the upper limb underwent the reconstructive procedures with the free peroneal perforatorbased sural neurofasciocutaneous flap transfers. 4 patients were men and 2 were women, with the age ranging from 19 to 60 years. The causes of the injury included 4 motor vehicle accidents, and 2 massive machinery trauma. The area of the flap ranged from 16 cm × 8 cm to 30 cm × 10 cm, and the length of the perforator pedicle was 4 cm to 6 cm. Results A mean of 5.3 perforating vessels of the peroneal artery was noted in the specimen. The peroneal perforator that located at the junction of the middle and lower thirds of the fibula was found suitable for microsurgery, with the external diameter and the length being (1.21 ± 0.13)mm and (4.6 ± 0.8)cm respectively. All the 6 flaps survived completely without necrosis. No severe venous congestion was observed. All the patients were satisfied with the aesthetic outcome postoperatively at 3 to 12 months'follow-up. There were no major donor site complications. Conclusion The free sural neurofasciocutaneous flap based on a single peroneal perforator is an excellent tool for reconstruction of extensive soft tissue defects in the upper limb.

BACKGROUND:Studies have shown that the vacuum sealing drainage technology can effectively promote the wound healing, and it has a wide prospect of clinical application, but there are few reports addressing the
treatment of diabetic foot.
OBJECTIVE:To discuss the clinical effect of vacuum sealing drainage technology in the treatment of diabetic foot wounds.
METHODS: Sixty diabetic foot patients were randomly divided into two groups: traditional treatment group,
regulating blood sugar level, dressing and traditional debridement; vacuum sealing drainage group, conventional treatment combined with the vacuum sealing drainage technology. The clinical efficacy of two treatments for
diabetic foot was evaluated.
RESULTS AND CONCLUSION: Compared with the traditional treatment group, the vacuum sealing drainage
showed better outcomes in switching frequency, stable blood sugar control, preparation time, wound healing time and cure rate (P < 0.05). It indicates that the vacuum sealing drainage technology in the treatment of diabetic foot ulcers can resolute wound inflammation, stimulate the growth of granulation, create a favorable surgical condition for secondary skin grafting or flap coverage, significantly shorten the treatment time, and exhibit better curative effects than the traditional treatment.

Objective:To implement an intervention with community-dwelling middle-aged and elderly people through a new science promotion approach, and to evaluate changes in the level of bone health awareness.Methods:From April 2017 to June 2017, 200 community-dwelling middle-aged and elderly people aged 50 years and over were randomly included.They were divided into the intervention group receiving a new science promotion intervention(n=100, with 50 males and 50 females)and the control group(n=100, with 50 males and 50 females). Baseline and follow-up assessments of bone health awareness were performed before and after the one-year intervention.A questionnaire survey on preferences for different types of science promotion articles in WeChat accounts was conducted.Differences in scores for intervention effects before and after intervention were compared between the two groups.Potential influencing factors for the scale score were examined by a multi-factor analysis.Results:After one year of intervention, scores for intervention effects were higher in the intervention group than in the control group( P<0.001). In the intervention group, scores were higher after intervention than before intervention( P<0.001). In the control group, scores after follow-up were slightly higher than those at baseline(29.4±11.4 vs.27.9±10.1, P<0.001). The increase in scores before and after intervention was greater in the intervention group than in the control group( P<0.001). Baseline score, group designation, history of drinking and diabetes impacted the scores in middle-aged and elderly women, while other factors did not.Most middle-aged and older people preferred texts illustrated with pictures, and older people were more receptive to videos. Conclusions:The new science promotion method is beneficial to bone health management, can improve bone health awareness in middle-aged and elderly people.
