Objective To investigate the effect of ropivacaine preconditioning on the toxicity of ropivacaine to ND7/23 cells.Methods ND7/23 cells were cultured in DMEM culture medium at 37℃ in 5% CO2 incubator for 24 h at a concentration of 1 × 106/ml. The cells were randomly divided into 3 groups ( n = 3 each) ;control group (group C), ropivacaine group (group R) and ropivacaine preconditioning group (group RP). In group R, the cells were exposed to 1% ropivacaine 100 μl and incubated for 1 h. In group RP, the cells were exposed to 0.02% ropivacaine 100 μl for 15 min, after ropivacaine was washed out, 1% ropivacaine 100 μl was then added and the cells were incubated for 1 h. The cell viability was measured using CCK-8 assay and apoptosis using Annexin-V/PI staining.Results Compared with group C, the cell viability was significantly decreased, while the early apoptotic rate and late apoptotic rate were significantly increased in groups R and RP ( P ＜ 0.05). Compared with group R, the cell viability was significantly increased, while the early apoptotic rate and late apoptotic rate were significantly decreased in group RP (P ＜ 0.05) .Conclusion Ropivacaine preconditioning can protect ND7/23 cells from bupivacaine-induced cytotoxicity through inhibiting apoptosis.

With the rapid development of pharmacogenetics, more and more studies have shown evidence in the association between polymorphisms at the human leukocyte antigen (HLA) loci and severe adverse drug reactions (SADRs). Several HLA-B alleles proved to be associated with SADRs for drugs such as carbamazepine, allopurinol, lamotrigine, and lfucloxacillin. hTe USA Food and Drug Administration (FDA) has even recommended routine screening for HLA-B allele before the use of abacavir and carbamazepine. With the completion of human genome project and the Hapmapproject, several new pharmacogenetics approaches such as genome-wide association study (GWAS) have emerged. hTese newly developed methods will undoubtedly accelerate the identiifcation and clinical utilization of the pharmacogenetic biomakers. In addition, the immunogenetic mechanisms by which the HLA alleles cause SADRs are explored at the cellular and molecular level. hTis review focuses on the recent progresses in HLA alleles and ADRs regarding both the clinical translation and modern pharmacogenetic methods.

ObjectiveTo investigate the clinical results of hepatectomy for bleeding of spontaneous rupture of hepatocellular carcinoma (HCC). MethodsThe clinical data of 24 cases admitted to our hospital from Jan 1990 to Mar 2004 was analyzed retrospectively.ResultsSurgical hemostasis was achieved successfully in 100.0% (24/24) of patients. The postoperative mortality rate was 4.1% (1/24), and the (complication) rate 12.5%(4/24). Liver function recovered within two weeks after operation. The length of hospital stay was 14.756.25 days.Twenty-one patients were followed-up from 6 month to 36 months. 8 patients died from recurrence within 10 months postoperatively; 10 patients survived over 1 year, 1 patient over 2 years and 1 over 3 years. The overall 1-year survival rate was 58.3%(13/24).ConclusionsIn the management of bleeding of spontaneous rupture of HCC, hepatectomy can effectively stop the bleeding and excise the tumor at the same operation. In some patients, a radical excision can be achieved, and, if the (patient)s condition permits it, hepatectomy should be the treatment of choice.

Objective To investigate the effect of etomidate on porcine adrenal cortical cells and the influence of preconditioning with small dose etomidate. Methods Porcine adrenal cortical cells were cultured in Dulbecco's modified Eagle's medium (DMEM) supplemented with 15% fetal bovine serum at 37℃ in 5% CO2 incubator for 24 h. The concentration was 2 × 106/ml. The experiment was performed in 2 parts. In part Ⅰ the cells were exposed to 50, 100, 200, 300, 400, 500 and 1000 mol/L etomidate respectively and incubated for 6, 12and 24 h, while in control group, the cells were exposed to 0.5% dimethylsulfoxide (DMSO). Cell viability was measured using CCK-8 assay and apoptosis by flow cytometry, and the 50% inhibitory concentration (IC50) of etomidate was calculated at 24 h of incubation. In part Ⅱ the cells were exposed to 0.6 μmol/L etomidate for 1 h and were allowed to recover for 4 h after etomidate washout, then etomidate 325 μmol/L was added and the cells were incubated for 24 h. Cell viability and apoptosis were assessed and the IC50 of etomidate was calculated as in part Ⅰ .Results Etomidate inhibited viability of porcine adrenal cortical cells and induced apoptosis in a dose- and time-dependent manner. The IC50 of etomidate at 24 h of incubation was 325 μmol/L. Preconditioning with0.6 μmol/L etomidate for 1 h attenuated the apoptosis induced by etomidate 325 μmol/L. Conclusion Etomidate can inhibit cell viability and induce apoptosis in a dose- and time-dependent manner. Preconditioning with small dose etomidate has protective effect.

Objective Macrophage activation syndrome (MAS) is a severe, potentially life-threatening clinical condition. The clinical features including precipitating events, clinical presentations, treatment strategies, outcome in systemic onset juvenile idiopathic arthritis (So-JIA) children with MAS were reviewed. Perforin A91V gene analysis was also performed. Methods Retrospective review of fourteen MAS cases with So-JIA from 2003 to 2008 from a collected database. Gene-specific polymerase chain reaction ( PCR) primers were used to analyze the perforin A91V gene polymorphism. Results Fourteen patients with age from 4 months to 12 years were considered to have evidence of MAS. Nine of them were boys. The primary diagnosis was systemic onset juvenile idiopathic arthritis. No medication was identified as trigger. Eleven of them had infections prior to MAS. Among them specific infectious agents were identified in four patients. High fever, new onset of hepatosplenomegaly, lymphadenopathy, liver function abnormality, abnormal lipid metabolism and hemophagocytosis were common clinical features. Two cases presented with acute respiratory distress syndrome (ARDS). Multiple organ failure (MOF) occurred in three cases. Three patients died. The variant form (NCBI: SNP rs35947132) of perforin A91V gene was detected in seven systemic onset juvenile idiopathic arthritis compolicated with MAS cases. However no mutation was detected. Clucocorticoid, intravenous immunoglobulin, immunoimpressive therapy were effective treatment of this condition. Plasmapheresis (HP) was successfully used in one case with severe MAS. Conclusions MAS is a rare and potentially fatal complication of childhood rheumatoid diseases such as systemic onset juvenile idiopathic arthritis. In this series, majority of them were male and most of them were preceded by infection. Bone marrow studies support the diagnosis. MOF may be a poor prognostic sign of So-JIA. Aggressive and early therapy is essential. There is no relationship between the variant form (NCBI: SNP rs35947132) of perforin A91V gene and So-JIA with MAS in this small sample's study. More research need to be done by increasing sample's numbers.
