Background: Anastomotic leakage is one of the most serious complications that can occur after laparoscopic-assistedsphincter-preserving surgery for middle- and low-grade rectal cancer.

Objectives: To explore the cause, prevention, and treatment of anastomotic leakage after sphincter-preserving surgery for middle- and low-grade rectal cancer under laparoscopy.

Methods: The clinical data from patients with mid- and low-grade rectal cancer who underwent laparoscopic-assistedanus-preserving surgery in the anorectal surgery department of our hospital have been analyzed.

Objective: To evaluate the safety and feasibility of single-incision laparoscopic surgery+1 (SILS+1) radical resection of sigmoid and upper rectal cancer.

Methods: The clinical data of 30 consecutive patients with sigmoid and upper rectal cancer who underwent SILS+1 radical resection between October 2018 and January 2020 in our hospital were retrospectively analyzed. An initial 5-cm periumbilical transverse incision was made.

Objective: To investigate the clinical use of a large C suture in the procedure for prolapse and hemorrhoids (PPH) for treatment of mixed hemorrhoids.

Methods: Patients with mixed hemorrhoids (grade III or IV) who underwent treatment with a large C suture during PPH in the Affiliated Hospital (Group) of Putian University from 1 April 2018 to 31 March 2019 were enrolled in this retrospective study. The incidences of anastomotic stenosis and anastomotic hemorrhage after the operation were observed.

Root nodules in peanut (Arachis hypogaea L.) could directly utilize nitrogen (N) in the atmosphere as N source, which plays an important role in the N supply in peanut. However, little is known about the mechanism of efficient N fixation by root nodule.

Five previously undescribed compounds including two triterpenoid aglycones, 3β,23-dihydroxy-1,12-dioxo-olean-28-oic acid and 3β,23,27-trihydroxy-1-oxo-olean-12-ene-28-oic acid, and three triterpenoid glucosides cyclocarioside L-N, along with 17 known compounds were isolated from a CHCl-soluble extract of the leaves of Cyclocarya paliurus. Two 27-nor-triterpenoid glycosides were isolated from the genus for the first time. Furthermore, the characterized compounds were tested for the inhibitory effects on apoliprotein B48 secretion in Caco-2 cells.

Two new (1-2) and two known C steroids (3-4) were isolated from the roots of Cynanchum atratum. Their structures were elucidated by detailed 1D and 2D spectroscopic. The MTT assay showed that compounds 1-4 displayed obvious cytotoxic activities against HepG2 cells with IC values ranging from 10.

A total of twenty genotypes of peanut (Arachis hypogaea) were used to investigate the differences in nitrogen (N) utilization characteristics in a pot experiment with N isotope tracing analysis. Results showed the main N sources for peanut in high fertility soils following as soil N source > N fixed by root nodule source > fertilizer N source. The N uptake and accumulation in peanut from total N and the three N supplied sources (fertilizer N, soil N and N fixation) varied among the different genotypes.

Background: Hepatic steatosis (HS) is the early stage of nonalcoholic fatty liver disease which is caused by impaired hepatic lipid homeostasis. Cyclocarya paliurus, an herbal tea consumed in China, has been demonstrated to ameliorate abnormal lipid metabolism for the treatment of metabolic diseases.

Purpose: We aimed to investigate the regulative effect of chloroform extract from Cyclocarya paliurus (ChE) on treatment of HS, as well as key factors involved in hepatic lipid metabolism.

Two new (1-2) and three known (3-5) C21 steroidal glycosides were isolated from Cynanchum stauntonii. Their structures were elucidated on the basis of 1D and 2D-NMR spectroscopic data as well as HRTOFMS analysis. The cytotoxicity of the compounds against A549, HepG2, and 4T1 cell lines were evaluated by MTT assay.
