The pollination of (Orchidaceae) in South China: When butterflies take sides.

is one of the largest terrestrial genera in the family Orchidaceae. Most field studies on species with greenish-white and nocturnal scented flowers are pollinated by nocturnal hawkmoths and settling moths. However, presents reddish flowers lacking a detectable scent and fails to fit the moth pollination syndrome.

A retrospective pilot study to examine the feasibility of real-time navigation for laparoscopic liver resections in intrahepatic cholangiocarcinoma using fusion indocyanine green fluorescence imaging.

Background And Objectives: Recently, PINPOINT, a novel laparoscopic fusion indocyanine green fluorescence imaging (IGFI) system has become available for laparoscopic liver resection. This study aims to characterize fluorescence patterns of intrahepatic cholangiocarcinoma (ICC) using the negative counterstaining method in laparoscopic anatomical hepatectomies of ICC.

Methods: Eleven consecutive patients, diagnosed with intrahepatic cholangiocarcinoma and underwent laparoscopic liver resection between April 2017 and December 2018, were retrospectively reviewed.

Combined gastroscopic and choledochoscopic transabdominal nasobiliary drainage.

Common bile duct (CBD) stones are a frequent problem in Chinese populations, and their incidence is particularly high in certain areas (Wang et al., 2013). In recent years, laparoscopic common bile duct exploration (LCBDE) and endoscopic retrograde cholangiopancreatography (ERCP) have been the main surgical procedures for CBD stones, although each has different advantages and disadvantages in the treatment of choledocholithiasis (Loor et al.

[Fitness of sexual reproduction of Toona ciliata var. pubescens natural populations and their sexual reproduction and regeneration].

To examine the reproduction fitness coefficients and individual-level fitness of Toona ciliata var. pubescens, their sexual reproduction and natural regeneration were investigated during 2006-2016, with four natural populations in Jiulianshan National Reserve as test objects. The results showed that there were only 2-10 trees for the natural populations of T.

Laparoscopic Versus Open Resection of Small Bowel Gastrointestinal Stromal Tumors: Systematic Review and Meta-Analysis.

Background: Laparoscopic resection (LAP) for small bowel gastrointestinal stromal tumors (GISTs) is not as common as for stomach. This study aimed to evaluate the safety and efficacy of LAP for small bowel GISTs with systematic review and meta-analysis.

Methods: The Web of Science, Cochrane Library, Embase, and PubMed databases before December 2016 were comprehensively searched to retrieve comparative trials of LAP and conventional open resection (OPEN) for GISTs of small bowel with a relevance of review object.

Is Laparoscopic Hepatectomy a Safe, Feasible Procedure in Patients with a Previous Upper Abdominal Surgery?

Background: Laparoscopic liver resection has become an accepted treatment for liver tumors or intrahepatic bile duct stones, but its application in patients with previous upper abdominal surgery is controversial. The aim of this study was to evaluate the feasibility and safety of laparoscopic hepatectomy in these patients.

Methods: Three hundred and thirty-six patients who underwent laparoscopic hepatectomy at our hospital from March 2012 to June 2015 were enrolled in the retrospective study.

Suppression of autophagy by chloroquine sensitizes 5-fluorouracil-mediated cell death in gallbladder carcinoma cells.

Autophagy1 is a complex of adaptive cellular response that enhances cancer cell survival in the face of cellular stresses such as chemothery. Here we show that in human gallbladder carcinoma (GBC) cells lines, SGC-996 and GBC-SD, autophagy is induced by the DNA damaging agent 5-fluorouracil (5-FU). While in combination with the pre-treatment of chloroquine (CQ), a inhibitor of autophagy, the inhibition of 5-FU to the proliferation and viability of GBC cells was potentiated.

Repair of bile duct defect with degradable stent and autologous tissue in a porcine model.

Aim: To introduce and evaluate a new method to repair bile duct defect with a degradable stent and autologous tissues.

Methods: Eight Ba-Ma mini-pigs were used in this study. Experimental models with common bile duct (CBD) defect (0.

Experimental study of colonic anastomosis with a degradable stent in a porcine model.

Background: Intestinal anastomosis is a major technical component of gastrointestinal procedures. We have developed a new procedure of colonic anastomosis with a degradable stent. This article evaluates this procedure.

Laparoscopic left hemihepatectomy: a safety and feasibility study of 19 cases.

Background: Laparoscopic liver resection was performed at some institutes. The procedure mainly included local resection, segmentectomy, and left lateral segmentectomy. With experience accumulation and technique innovation, laparoscopic left hemihepatectomy was performed in selected patients.
