This research introduces a new method to analyze the diffusion information of human brain. By use of the multi b value diffusion data and a new algorithm, a new diffusion parameter (Rd) was computed, and a new image was reconstructed. Through quantitative research on the brains of 25 normal adults, the new method can improve the signal-to-noise ratio (SNR) apparently and distinguish the different brain tissues effectively, compared to the apparent diffusion coefficient. The new method can improve the sensitivity to diffusion.

Objective:
In order to achieve superior aesthetic outcomes of reconstructed ear, analyze and summarize clinical therapeutic effect in completely applying expanded retroauricular flap to encapsulate cartilage scaffold in total auricular reconstruction.
Methods:
From January 2016 to October 2017, fifty-three congenital microtia patients were treated. A kidney-shaped tissue expander with 50 ml capacity was embedded under retroauricular skin in the first-stage. After excessive expansion to 70 ml and remaining stable for 4 weeks, secondary operation was performed to completely encapsulate cartilage scaffold with expanded retroauricular skin. Postoperative follow-up was carried out on a routine basis.
Results:
All patients had undergone operations successfully with primary healing of incision. Blood supply of the retroauricular flaps was excellent, and cartilage scaffolds totally survived with no infection and absorption. Satisfactory aesthetic outcome along with clear structure, reasonable symmetry and suitable auriculocephalic angle was acquired in all cases. No color aberration was observed between the front and back side of reconstructed ear. Scars of retroauricular incisions and costal cartilage harvesting incisions were unconspicuous.
Conclusions
Only using expansive retroauricular flap to fully cover reconstructed cartilage scaffold is reasonable and simple without skin grafting, which is worthy of more application in microtia treatment.

Deep sternal wound infections (DSWIs) are serious postoperative complications of sternotomy and have a great impact on the postoperative rehabilitation and life safety of patients. At present, DSWIs is mainly treated by infection control, thorough debridement and reconstruction of chest wall. Reconstruction of chest wall includes reconstruction of bony structures and soft tissues of the chest wall, among which the various muscle flaps available for soft tissue reconstruction have different characteristics and application indications. Therefore, individualized treatment plans for chest wall reconstruction should be made according to the specific situation of patients. In this article, the current chest wall reconstruction protocols and the progress of clinical research for DSWIs were reviewed, with a view to providing assistance in clinical treatment and follow-up studies.
