Computer tomography-guided negative pressure drainage treatment of intrathoracic esophagojejunal anastomotic leakage: A case report.

Background: Esophagojejunal anastomotic leakage (EJAL) is a serious and potentially crucial complication of total gastrectomy and represents the major cause of postoperative death, with a mortality rate of up to 50%. However, treatment remains challenging and controversial. We report here the case of a patient whose intrathoracic EJAL was successfully treated with computer tomography (CT)-guided negative pressure drainage treatment.

[Evaluation of the effects of two different modes of orthognathic surgery on upper airway morphology in patients with skeletal Class Ⅲ malocclusion].

Purpose: To establish three-dimensional models of upper airway pre- and post-orthognathic surgery in patients with skeletal Class Ⅲ malocclusion, and to compare the effects of different modes of orthognathic surgery on the cross-sectional areas and volumes of upper airway.

Methods: Twenty-eight patients with skeletal Class Ⅲ malocclusion were divided into 2 groups. Group A (12 patients) underwent bilateral sagittal split ramus osteotomy(BSSRO) for mandibular setback, named single jaw surgery group; group B (16 patients) underwent BSSRO + Le Fort I osteotomy for mandibular setback and maxillary advancement, named bimaxillary surgery group.

[Study on determination and pharmacokinetics of metabolites from Folium Mori extract in rats].

Objective: To establish a RP-HPLC method for simultaneous determination of total quercetin, kaempferol and isorhamnetin in rat plasma after oral administration of Folium Mori extract (FME).

Methods: After a single dose of FME (110 mg/kg) was taken, rat plasma samples were collected. The samples were hydrolyzed with hydrochloric acid (c=3.

Current treatment of rectovaginal fistula in Crohn's disease.

Rectovaginal fistula (RVF) continues to be the most difficult perianal manifestation of Crohn's disease to treat. This devastating and disabling complication has a significant impact on patients' quality of life and presents unique management challenges. Current therapeutic approaches include many medical therapeutics and surgical treatments with a wide range of success rates reported.

Identification of metabolites of Danggui Buxue Tang in rat urine by liquid chromatography coupled with electrospray ionization time-of-flight mass spectrometry.

A method coupling liquid chromatography with electrospray ionization time-of-flight mass spectrometry (LC/ESI-TOF/MS) has been developed for rapid and sensitive analysis of rat urinary metabolite profile of Danggui Buxue Tang (DBT), a well-known Chinese herbal formula. After oral administration of DBT, urine samples were collected during 0-24 h, and then pretreated by solid-phase extraction. A total of 68 compounds including 13 parent compounds and 55 metabolites were detected in the drug-containing urines compared with blank urines.

[Study on applying principle component analysis to data processing on chromatographic fingerprints for Pinellia Cum Bile].

Objective: To explore the utility of principle component analysis (PCA) on chromatographic data for quality control to Dannanxing (Pinellia Cum Bile).

Method: Chromatographic fingerprints of sample were determined by TLC, PCA and multivariat analysis were used for data processing.

Result: The quantitative differences among samples procesed with different biles and heating time were found with the method.
