[Three methods for controlling presacral massive bleeding during pelvic operations].

Objective: To evaluate three different methods for controlling presacral massive bleeding during pelvic operations.

Methods: Clinical data of 11 patients with presacral massive bleeding during pelvic operation at The Sixth Affiliated Hospital of Sun Yat-sen University and 157 Branch Hospital of Guangzhou General Hospital of Guangzhou Military Command from January 2001 to January 2016 were analyzed retrospectively. Hemostasis methods for presacral massive bleeding during operation included gauze packing (whole pressure), drawing pin (local pressure) and absorbable gauze (absorbable gauze was adhered to bleeding position with medical glue after local pressure).

Nogo-p4 Suppresses TrkA Signaling Induced by Low Concentrations of Nerve Growth Factor Through NgR1 in Differentiated PC12 Cells.

Background: Regeneration of injured axons in adult mammalian central nervous system (CNS) is not spontaneous. Nogo is a major inhibitory molecule contributing to axon regeneration failure. The molecular mechanisms of Nogo inhibition of axon regeneration are not completely understood.

[Study on recovery and its influencing factors of ferulic acid and tetramethylpyrazine in cerebral microdialysis probe].

To establish a method for detecting microdialysis recovery of tetramethylpyrazine (TMP) and ferulic acid (FA) and investigating the influencing factors, providing the basis for further in vivo microdialysis experiments. The concentration of FA and TMP in dialysates were determined by high pressure liquid chromatography ( HPLC) and probe recovery were calculated respectively. The influence of the flow rates, medium concentration, temperature and in vivo probe stability on the recovery of FA and TMP were investigated by using concentration difference method (incremental method and decrement method).

[Research on chemical constituents of xuefu zhuyu decoction].

Objective: To investigate the chemical constituents of Xufu Zhuyu decoction.

Methods: Silica gel column chromatography, Sephadex LH-20 chromatography and crystallization were employed for the isolation and purification. The structures were elucidated by physicochemical properties and spectral analysis.

[Effect of peritoneal lavage with povine-iodine on prevention of postoperative sepsis after exposure of peritoneal cavity to sea water in rat].

Objective: To observe the effects of peritoneal lavage with povine-iodine on prevention of sepsis after exposure of peritoneal cavity to sea water in rat.

Methods: Eighty-four SD rats were randomly divided into two groups, and the peritoneal cavity was exposed to sea water. Rats in group A were not treated (group A, n=42), and the peritoneal cavity was lavage with povine-iodine in group B (n=42).

[Effect of hypotonic liquid containing colloid on hemorrhagic dogs with celiac seawater immersion wound].

Objective: To determine hypotonic liquid containing colloid on hemorrhagic dogs with celiac seawater immersion wound.

Methods: Thirty-five dogs were randomly divided into five groups: control group (group A), 0.9% NaCl therapy group (group B) and 0.

Consequence alimentary reconstruction in nutritional status after total gastrectomy for gastric cancer.

AIM:To investigate the effect of gastroenteric reconstruction on the nutritional status of patients with gastric cancer after total gastrectomy.METHODS: From 1989-1994, nutritional status was studied in 24 patients, including 12 patients with the gastric reservoir and pyloric sphincter reconstruction (GRPS), 7 with Braun's esophago-jejunostomy (EJ) and 5 with Lawrance's Roux en Y reconstruction (RY).The ability of these patients to ingest and absorb the amount of nutrients was examined and compared, and metabolic balance test was performed to compare the efficiency of those patients to accumulate and use the absorbed nutrients.
