Objective To study the effects of lidocaine on inflammatory mediators and myocardial enzymes in patients undergoing off-pump coronary artery bypass grafting (OPCAB).Methods Twenty patients underging OPCAB were randomly divided into 2 groups of L and C with 10 cases each. After anesthesia induction, group L was given a bolus of lidocaine 2 mg/kg, which was followed by an infusion of lidocaine 2 mg·kg~(-1)·h~(-1) till the end of operation. Group C was given normal saline instead of lidocaine as the control. Blood samples were taken for the measurements of TNF-a, IL-8, SOD, MDA, cTnⅠ, CK-MB and MYO. The hemodynamics, early postoperative clinical informations and ICU and hospital stay were recorded. Results The increases of TNF-α and IL-8 were significiently less in group L than those in group C(P<0.01 or P<0.05). MDA at 24 h after operation was higher in group C than that in group L(P<0.05). The increases of CK-MB and cTnⅠ at 24 h and 48 h after operation were significiently less in group L than those in group C(P<0. 01 or P <0. 05). The ICU and hospital stays were shorter in group L than those in group C(P<0. 05). Conclusion Continuous infusion of lidocaine during OPCAB can decrease the inflammatory mediators and myocardial enzymes and protect the myocardium.

Objective To identify the Candida species isolated from recurrent vulvovaginal candidiasis( RVVC) pa-tients, and provide etiologic datum of RVVC. Methods All Candida isolates, including those from vulvovaginal candidiasis ( VVC) and RVVC patients, were identified by using CHROMagar chromogenic medium and VITEK2 yeast identification kits. Results The proportions of nonalbicans species from nonpregnant RVVC relapse patients and pregnant VVC patients were both significantly higher than those from nonpregnant VVC patients ( P<0. 05 ) . Among pregnant patients, the percentage of C. albicans isolated from RVVC relapse was couer, but there was no significant difference of C. albicans species percentage between RVVC and VVC patients. Conclusion RVVC may be related to the recurrence of same Candia species and the reinfection of different Candia species. Pregnant women may be more inclinable to suffer from disorder caused by nonalbicans species.

Drug addiction is a chronic relapsing brain disease that is characterized by compulsive drug use and persistence of drug craving. Drug abuse can lead to changes in the neuron structure and function of plasticity,alterations in molecules and cells,and ultimately to individual abnormal behavior. Current studies have found that epigenetic changes leading to the sustainability of gene expression is an important mechanism of drug addiction. In this review,we will systematically summarize the latest advances in epigenetic mechanisms of drug addiction. This review is expected to provide robust evidence that repeated exposure to drugs of abuse induces changes within the brain′s reward regions in three major modes of epigenetic regulation-histone modifications such as acetylation and methylation , DNA methylation,and non-coding RNAs. It promises a new perspective from which to gain insights into the genetic and epigenetic mechanisms of drug addiction and a new area for epigenetic research on clinical drug addiction treatment.

BACKGROUND: The mitofusin 2 (Mfn2) may affects vascular smooth muscle cell Ras protein and suppress cellular proliferation through inhibition of extracellular signal-regulated protein kinase signaling pathway, which plays an important role in pathogenesis of vascular disorders such as hypertension, atherosclerosis and post-angioplasty restenosis. Mfn-2 gene amino acid sequence of the first 442 serine serves as protein kinase A (PKA) phosphorylation site, which is closely related to its phosphorylation status and may be involved in its functional regulation.OBJECTIVE: To investigate the effect of Mfn2 gene with PKA phosphorylation site deletion[Mfn2-PKA (△)] on inhibiting the proliferation of vascular smooth muscle cells and related signaling pathway.METHODS: Vascular smooth muscle cells of rats infected by recombinational adenovirus carrying green fluorescent protein,Mfn2 gane and Mfn2-PKA (△), were subcultured for 3-10 passages and randomly divided into 4 groups: ① Control group without intervention. ② Control group infected with adenovirus carrying green fluorescent protein. ③ Experiment group infected with adenovirus carrying Mfn-2 gene.④ Experiment group infected with adenovirus carrying Mfn2-PKA (△). Laser confocal microscopy was used to observe the locations of Mfn2 gene with and without PKA in cells. The expressions of extracallular signal-regulated protein kinase, Mfn2 gone and Mfn2-PKA (△) were determined by Western blot analysis. The growth curve of the vascular smooth muscle cells was explored by MTT.RESULTS AND CONCLUSION: The Mfn-2 and Mfn2-PKA (△) both expressed protein-specific bands in vascular smooth muscle cells. Two kinds of gone expression products were mainly located at the out membrane of mitochondria. Compared with the control group and adenovirus carrying green fluorescent protein group, the absorbance values at 3, 4, 5, 6 days were significantly reduced in adenovirus carrying Mfn2 group (P < 0.01), and no obvious changes were observed in adenovirus carrying Mfn2-PKA (△) group. Compared with the control group and adenovirus carrying green fluorescent protein group, the extracellular signal-regulated protein kinase expression was significantly reduced in adenovirus carrying Mfn2 group (P < 0.01), and no obvious changes were observed in adenovirus carrying Mfn2-PKA (△) group. Mfn2-PKA (△) located at the out membrane of mitochondria, has no effect on suppressing the proliferation of vascular smooth muscle cells, and no inhibition effect on extracellular signal-regulated protein kinase signaling pathway.
