In the present era laparoscopic cholecystectomy (LC) has become the gold standard treatment of choice for gallstone disease. This technique has made a new revolution in minimal invasive surgery, but also the spectrum of complications has changed. In this paper we shared our personal experience of LC in 400 hundred cases from January 2007 to December 2010, its complications and prevention. According to our experience the complications were liver bed injury (n=32, 8%), spilled gall stones (n=29, 7.25%), port site infection (n=11, 2.75%), vascular injury (n=18, 4.5%), conversion to open surgery (n=16, 4%), biliary leak (n=10, 2.5%), bowel injury (n=3, 0.75%), CBD stricture (n=4, 1%) and umbilical port hernia (n=2, 0.5%). Before the procedure, patient consent and awareness to all possible complications which may occur intra-operatively is very important. A good surgical team and experience in this procedure seems to prevent hazardous complications.

Long noncoding RNAs (lncRNAs) play critical roles in cellular homeostasis. However, little is known about their effect in developing rat brains with hypoxic-ischemic brain damage (HIBD). To explore the expression and function of lncRNA in HIBD, we analyzed the expression profiles of lncRNAs in hypoxic-ischemic (HI) brains and sham control using microarray analysis. The results showed a remarkable difference in lncRNA between HI and sham brains. A total of 322 lncRNAs were found to be differentially expressed in HI brains, compared to sham control. Among these, BC088414 was one of the most significantly urpregulated lncRNAs. In addition, 375 coding genes were differentially expressed between HI brains and sham control. Pathway and gene ontology analysis indicated that the upregulated coding genes mostly involved in wounding, inflammation and defense, whereas the downregulated transcripts were largely associated with neurogenesis and repair. Moreover, coding non-coding co-expression network analysis showed that the BC088414 lncRNA expression was correlated with apoptosis-related genes, including Casp6 and Adrb2. Silencing of lncRNA BC088414 in PC12 cells caused reduced mRNA level of Casp6 and Adrb2, decreased cell apoptosis and increased cell proliferation. These results suggested lncRNA might participate in the pathogenesis of HIBD via regulating coding genes.

Trans-CSF brain stimulation is on of applied methods of stimulation in posttraumatic vegetative state. The paper analyzes application of this technique under the control by different methods of electrophysiological monitoring. Authors suggest principles of selection of stimulation parameters and detectable criteria of its effectiveness.
