[Analysis of Total Organic Carbon Source Differences Between New and Old Cascade Reservoirs using Carbon and Nitrogen Isotopes].

The ecological problems due to reservoir construction are causing unprecedented concern. To reveal the differences in organic carbon distribution characteristics and sediment sources of total organic carbon (TOC) between the old and new reservoirs, water samples, and sediment samples from reservoirs constructed in the three different periods of Miaowei, Gongguoqiao, and Dachaoshan were collected in November 2017. The temperature (), dissolved oxygen (DO), TOC, redox potential (ORP), total nitrogen (TN), and total phosphorus (TP) of the water samples were measured.

[Speciation and Transformation of Phosphorus in Sediments During the Redox Cycle].

To study the mechanism of phosphorus cycling in sediment during the redox cycle, changes in physicochemical properties of overlying water and various forms of phosphorus in sediments were investigated as a way to quantify the redistribution of phosphorus. Additionally, the effect of the release flux of phosphate from sediments under controlled redox conditions was analyzed. The results showed that the redox potential Eh and the pH system, sulfur system, carbon system, and iron-related changes exhibited periodicity and played an important role in explaining the migration and transformation mechanism in the interface phosphorus of the sediment-water phase.

Clinical analyses of clustered microcalcifications after autologous fat injection for breast augmentation.

Background: Autologous fat injection for breast augmentation has been disputed with regard to its complications for many years, especially regarding calcifications, most of which present with benign features. In previous studies, clustered microcalcifications were not observed after fat injection for breast augmentation, which are usually regarded as malignant calcifications.

Methods: From July of 1999 to December of 2009, autologous fat injection for breast augmentation was performed for both breasts in 48 patients.

[Application of abdominoplasty and polypropylene to repair the abdominal defect].

Objective: To introduce a operation method of repairing the abdominal defect with abdominoplasty and polypropylene.

Methods: 27 patients were treated with abdominoplasty and polypropylene.

Results: Follow up 3 - 20 months, the focus in inferior abdominal wall were removed thoroughly.

[The application of pedicled anterolateral thigh fasciocutaneous flaps for reconstruction of perineal and inguinal defects].

Objective: To evaluate a method for the reconstruction of defects of perineum and groin with pedicled anterolateral thigh fasciocutaneous flaps.

Methods: From July 2003 to February 2005, 12 pedicled anterolateral thigh fasciocutaneous flap based on the perforators of lateral circumflex femoral artery had been designed and transferred to the defects of perineum and groin.

Results: Anterolateral thigh fasciocutaneous island flaps were performed in twelve patients.

[TRAM flap in conjunction with latissimus dorsi muscle flap for breast reconstruction].

Objective: To investigate a method to reconstruct the breast and repair the chest wall defects at the same time.

Methods: The operation procedure combined the transverse rectus abdominis myocutaneous (TRAM) flap with the latissimus dorsi muscle(LDM) flap for breast reconstruction and repair of chest wall defect. Two patients underwent delayed breast reconstruction using this technique.
