New surgical regimens are yet to be explored, which will follow the oncological principle of being “to- tal tumor free”, whilst fit into the unique characteristics of China's own medical system as well as pa- tients' demand. From 2007 to 2013, 143 patients with early stage breast cancer were included in the study, with the average age of 46.1 years. Fifty-three patients were subjected to modified breast con- serving surgery (MBCS)+latissimus dorsi (LD) flap reconstruction, 41 to skin sparing mastectomy (SSM)+implant+LD flap reconstruction, 29 to MBCS+distal transverse rectus abdominis myocutaneous (DTRAM) flap reconstruction, and 20 to SSM+DTRAM flap reconstruction. The results showed that out of the 143 patients, there was no graft loss. Minor complications included 4 cases of fat liquefaction, and 6 cases of seratoma, which all resolved after conservative treatment. Five patients had visible protu- berance in the abdomen, but not leading to any gastrointestinal symptoms. The reconstructed breasts all presented good shape. 96.7% of the patients were satisfied with the outcome. The follow-up period var- ied from 6 months to 60 months, and only one patient died from tumor metastasis in the brain. No local recurrence occurred. It was concluded that these two modified pedicled-flap surgeries are readily practi- cal, and aesthetically satisfactory, with high applicability in China. They do not compromise the on- cological outcomes, but also are well-accepted by Chinese patients.展开更多

The correspondence is established and expressions for the reconstructed f(R) models are determined. To study the evolution of the reconstructed models plots are generated. The stability of the calculated models are also investigated using the squared speed of sound in the background of the reconstructed gravities.展开更多

During the conditioning process, the decreases of total organic carbon (TOC) and soluble chemical oxygen demand (SCOD) were obviously in the supernatant especially for the acid modified cinder (ACMC), which could be attributed to the processes of adsorption and sweeping. The reduction of polysaccharide and protein in supernatant indicated that ACMC might adsorb EPS so that the tightly bound EPS (TB-EPS) decreased in sludge. In the case of ACMC addition with 24 g·L^-1, SRF of the sludge decreased from 7.85 × 10^12 m·kg^-1 to 2.06× 10^12 m·kg^-1, and the filter cake moisture decreased from 85% to 60%. The reconstruction of "floc mass" was confirmed as the main sludge conditioning mechanism. ACMC promoted the dewatering performance through the charge neutralization and adsorption bridging with the negative EPS, and provided firm and dense structure for sludge floc as skeleton builder. The passages for water quick transmitting were built to avoid collapsing during the high-pressure process.展开更多
