To evaluate the effect of Hexue mingmu tablets on traumatic hyphema caused by blunt ocular trauma.
●METHODS: Totally 150 patients of traumatic hyphema were divided into seven types by using ultrasound biomicroscopy combining with anterior segment abnormalities, each type was randomly classified as trial group and control group. The trial group was administered Hexue mingmu tablets, control group was treated by hemocoagulase.

A sensitive, rapid and accurate liquid chromatography-tandem mass spectrometric (LC-MS/MS) method with pre-column derivatization was developed for the simultaneous determination of erdosteine and its thiol-containing active metabolite in human plasma. Paracetamol and captopril were chosen as the internal standard of erdosteine and its active metabolite, respectively. Aliquots of 100 microL plasma sample were derivatized by 2-bromine-3'-methoxy acetophenone, then separated on an Agilent XDB-C18 (50 mm x 4.6 mm ID, 1.8 microm) column using 0.1% formic acid methanol--0.1% formic acid 5 mmol x L(-1) ammonium acetate as mobile phase, in a gradient mode. Detection of erdosteine and its active metabolite were achieved by ESI MS/MS in the positive ion mode. The linear calibration curves for erdosteine and its active metabolite were obtained in the concentration ranges of 5-3 000 ng x mL(-1) and 5-10 000 ng x mL(-1), respectively. The lower limit of quantification of erdosteine and its active metabolite were both 5.00 ng x mL(-1). The pharmacokinetic results of erdosteine and its thiol-containing active metabolite showed that the area under curve (AUC) of the thiol-containing active metabolite was 6.2 times of that of erdosteine after a single oral dose of 600 mg erdosteine tables in 32 healthy volunteers, The mean residence time (MRT) of the thiol-containing active metabolite was (7.51 +/- 0.788) h, which provided a pharmacokinetic basis for the rational dosage regimen.

Objective To investigate the morphological changes of different types of axonal injury in acute stage in rat brain with diffuse axonal injury(DAD caused by combined head injuries,and explore their relevant injury mechanisms. Methods SD rats were randomized into experimental (n=16)and normal control(=8)groups.According to the different injury times(6,24 h),the experimental group was equally divided into two subgroups(n=8).A new experimental facility was employed to induce DAI in rats.HE staining was conducted in different time points in the acute stage.Immunofluorescence assay was performed to detect the expressions of antibodies to β-Amyloid precursor protein(β-APP)and antibodies to neurofilament-68(NF-68)and electron microscope was also introduced to investigate the changes of axonemal ultrastructure.Results All injured rats experienced behavioral suppression:the coma in the experimental group was significantly prolonged as compared to that in the normal control group(P<0.05).Immunofluorescence assay for antibodies to β-APP and NF-68 revealed two distinct types of axonal injuly: β-APP confined to focal spheroidal axonal swellings and axonal retraction bulbs;while NF-68 Was only found within thin and elongate axonal segments. Electron microscope also demonstrated two different types of ultrastructure of axonal injury. Conclusion Impaired axonal transport and neurofilament compaction can occur independently in the process of axonal injury with different morphological changes.Multiple immunocytochemical approaches can help to fully assess the overall axonai response to traumatic brain injury.

OBJECTIVETo offer both the accurate three-dimensional anatomical information and algorithmic morphology of perforators in the lower leg for perforator flaps design.
METHODSThe cadaver was injected with a modified lead oxide-gelatin mixture. Radiography was first performed and the images were analyzed using the software Photoshop and Scion Image. Then spiral CT scan was also performed and 3-dimensional images were reconstructed with MIMICS 10.01 software.
RESULTSThere are (27 +/- 4) perforators whose outer diameter > or = 0.5 mm ( average, 0.8 +/- 0.2 mm). The average pedicle length within the superficial fascia is (37.3 +/- 18.6) mm. The average supplied area of each perforator is (49.5 +/- 25.5) cm2. The three-dimensional model displayed accurate morphology structure and three-dimensional distribution of the perforator-to- perforator and perforator-to-source artery.
CONCLUSIONSThe 3D reconstruction model can clearly show the geometric, local details and three-dimensional distribution. It is a considerable method for the study of morphological characteristics of the individual perforators in human calf and preoperative planning of the perforator flap.

This study is to elucidate the metabolic pathway of 1,2-[bis (1,2-benzisoselenazolone-3 (2H)-ketone)]-ethane (BBSKE) in rats. Rats were administrated with a single dose of BBSKE 200 mg x kg(-1). The metabolites in rat urine, feces, bile and plasma were identified by LC-MSn analysis. The characterization of fragment ions from LC-MSn chromatography and mass spectrometry was applied to the investigation of structures of metabolites. Three phase I metabolites were detected in rat urine and feces. Two of them were also found in plasma and one existed in bile. These products were derived from oxidized, methylated and S-methylated BBSKE, separately. One phase II glucuronide of BBSKE was also found in bile. Therefore, it is possible that BBSKE was metabolized by oxidization, methylation and glucuronidation.
