Nanocapsule-Based Reactive Nano-Fragrances with Slow-Release and Antibacterial Performances for Applications of Commodities.

Fragrances are widely used in everyday life. However, too fast volatilization rates and poor adhesion on substrates limit their applications. In this study, reactive nano-fragrance based on cyanuric chloride (CYC)-modified chitosan (CSCYC) were prepared by a solvent evaporation method.

Dual pH and Temperature-Sensitive Nanogels Loaded with Eugenol for Regulating Central Nervous System.

Fragrances have many biological activities such as anti-anxiety, anti-depression, and improving cognitive memory. However, most fragrances are so volatile that the useful lifespan of the fragrances is very short and excessive fragrance concentration makes us uncomfortable. In this study, dual pH and temperature-sensitive nanogels named EG@CPMONGs were prepared to encapsulate eugenol.

[Postoperative short-term complications of laparoscope-assisted transanal total mesorectal excision for rectal cancer after neoadjuvant therapy and their management: a single center report].

Objective: To summarize and analyze the postoperative short-term complications of laparoscope-assisted transanal total mesorectal excision (taTME) for rectal cancer patients after neoadjuvant therapy.

Methods: A prospectively established database on taTME patients at Peking University Cancer Hospital was screened with the following conditions: data retrieval from June 2016 to August 2018, pathologically confirmed adenocarcinoma, receiving preoperative neoadjuvant chemoradiotherapy or chemotherapy. The transabdominal procedure and the transanal procedure were performed simultaneously in the taTME operation.

[Short-term outcome of transanal total mesorectal excision for male low rectal cancer patients with "difficult pelvis" : a single center report from Peking University Cancer Hospital].

Objective: To explore the applicable value of transanal total mesorectal excision (taTME) in male low rectal cancer patients with narrow pelvis-"difficult pelvis", which remains difficult for both open and laparoscopic sphincter-saving operations.

Methods: Clinical data of male low rectal cancer patients diagnosed by pathology undergoing taTME between June 2016 and January 2018 at Peking University Cancer Hospital were collected. A retrospective cohort study was performed.

Neoadjuvant chemoradiation therapy for resectable esophago-gastric adenocarcinoma: a meta-analysis of randomized clinical trials.

Background: The efficacy and safety of preoperative chemoradiation therapy (CRT) for advanced esophago-gastric adenocarcinoma are still in question, and the prognosis of these patients is poor.

Methods: We systematically searched electronic databases from January 1990 to July 2014. The primary outcome was overall survival.
