OBJECTIVE:To study protective effects of Ketorolac tromethamine ophthalmic gel against Staphylococcus aureus corneal ulcer in rabbits. METHODS:S. aureus corneal ulcer in rabbits model was induced by corneal substance layer inoculation, and then divided into model group,positive control group (Clarithromycin ophthalmic gel),gel high-dose,medium-dose and low-dose groups(Ketorolac tromethamine ophthalmic gel 120,80,40 mg/ml),with 20 rabbits in each group. They were given re-levant medicine,once a day for 2 weeks. The keratopathy of rabbits was observed;the clinical efficacy and keratopathy score were compared. The change of ratina was observed under micrescope. RESULTS:Compared with model group,the keratopathy score de-creased while total effective rate increased in positive control group and gel groups after medication, and the effects of gel high-dose and low-dose groups were significantly lower than that of positive control group,with statistical significance(P<0.05). The retina of rabbits had not affected by the experiment. CONCLUSIONS:Ketorolac tromethamine ophthalmic gel has protective effect against S. aureus corneal ulcer in rabbits.

Objective: To observe the liver function changes and to analyze the risk factors in patients at peri-operative period of cardiopulmonary bypass surgery.
Methods: A total of 108 patients with cardiopulmonary bypass surgery were observed for their liver function at prior and 1, 2, 3, 6 days post-operation, the related risk factors for lever damage were studied by uni- and multivariate regression analysis.
Results: Compared with pre-operative indexes,① at 1, 2, 3 and 6 days post-operation, aspartate aminotransferase (AST), direct bilirubin (DBIL) were increased, serum albumin (ALB), cholinesterase (CHE) were decreased, and at 1, 2, 3 days post-operation, total bilirubin (TBIL) was increased, at 1, 2, 3 days post-operation, alkaline phosphatase (ALP) was decreased, while it increased at 6 days post-operation, allP<0.05;② glutamyl endopeptidase (GGT) was decreased at 1, 2 days post-operation, while it increased at 6 days post-operation,P<0.05;③glutamate pyruvate transaminase (GPT) was increased at 6 days after operation,P<0.05. Univariate regression analysis indicated that cardiothoracic ratio ≥ 0.56 (P<0.05, OR=2.900, 95% CI: 1.206~6.976), cardiopulmonary bypass time (P<0.05, OR=1.042, 95%CI: 1.017~1.068), aortic clamping time (P<0.05, OR=1.041, 95% CI: 1.012~1.070) and lactic acid level at 1 day after operation (P<0.05, OR=1.518, 95% CI: 1.182-1.948) were related to post-operative damage of liver function. Multivariate regression analysis presented that cardiopulmonary bypass time (P<0.05, OR=1.033, 95% CI: 1.007-1.059) and lactic acid level at 1 day after operation (P<0.05, OR=1.340, 95% CI: 1.028-1.745) were the independent risk factors for post-operative damage of liver function.
Conclusion: Multiterm of liver function could be damaged at the early stage after cardiopulmonary bypass surgery; cardiopulmonary bypass time and lactic acid level at 1 day after operation were the independent risk factors for peri-operative damage of liver function in relevant patients.

Objective To study the expression changes and profiles of nuclear structure and biogenesis-related genes in rat liver regeneration(LR). Methods Genes involved in nuclear structure and biogenesis were obtained by data collection and literature review.The gene expression changes during LR were checked by Rat Genome 230 2.0 array,and LR-related genes were identified by comparing gene expression difference between partial hepatectomy(PH) and sham operation(SO) groups.Results 406 genes were found to be LR-related.The numbers of initially and totally expressed genes occurring in the forepart(0.5-4 hours after PH) of LR,the prophase(6-12 hours after PH),the metaphase(12-66 hours after PH),and the anaphase(72-168 hours after PH) were 200,29,179,5 and 374,290,1?876,603,respectively.The numbers of their up-regulation and down-regulation were 1?224 and 496 times.The elevated transcription levels occur red to the nuclear organization and biogenesis-involved genes in the prophase and the metaphase of LR and to the nuclear membrane,nuclear matrix and nucleoplasm-involved genes in the metaphase;nuclear chromosome,nucleolus and nuclear functional protein complex-involved genes were up-regulated in the metaphase and the anaphase.Conclusion The expression of nuclear structure and biogenesis-related genes was active during LR,and it was tightly related with LR.

PurposeTo investigate the permeation of model drug,propranolol hydrochloride, through the excised porcine buccal mucosa. To study the influences of various factors on the buccal absorption also studied. MethodsUsing excised porcine buccal mucosa permeation test in vitro. By means of changing the medium pH, osmotic concentration, drug concentration, the concentration of various penetration enhancers including sodium glycodeoxycholate (GDC), sodium glycocholate (GC), dimethy1-β-cyclodextrin (DMβCD), and hydropropyl-β-cyclodextrin(HPβCD). The permeation rates and permeability coefficients(P) were determined and evaluated. The solubilities and apparent partition coefficients also determined in some tests. ResultsThe result showed that the P were increased when porcine buccal mucosae were pretreated with every penetration enhancement of certain concentration, increased as the pH of test solution rose from 4.9 to 9.1. The P remained constant as the concentration of propranolol hydrochloride increased from 5 to 80 mg/ml, decreased with the increasing of osmotic concentration Conclusions The absorption of propranolol hydrochloride through porcine buccal mucosa is a typical passive process, and affected by penetration enhancers, medium pH, osmotic concentration.

Stent fracture has been implicated as a cause of drug-eluting stent failure. The authors report here 2 cases with stent fractures which were diagnosed by coronary artery angiography and intravascular ultrasound (IVUS). Both of them received multiple-stent-implantation. Five stent fractures altogether were detected in two patients. All the involved stents were sirolimus-eluting ones. Angiographic study showed that three stent fractures were complete transverse linear fracture with stent displacement. IVUS demonstrated that three stent fractures were complete break and two were partial break. One fracture was located close to the overlapping site of two stents and another fracture was accompanied by the formation of a coronary aneurysm. Angiography and IVUS are helpful to identify stent fracture. In addition, IVUS is more likely to clarify the cause of stent failure as well as the mechanism of stent fracture.
