Objective To assess the effectiveness of tension-free vaginal tape obturator tape(TVT-O)as treatment of SUI by means of a systematic review and meta analysis.Methods Using the search terms"TVT,TVT-O,SUI,RCT,TOT",the literature in Chinese and English from January 2001 tO March 2007 on the difference of TVT and TVT-O was searched from MEDLINE,PUBMED,EMBASE,Google Scholar,CNKI,WAN FANG DATA,and criteria randomized controlled trials(RCTs)were studied by Meta-analysis in RevMan 4.2.At the same time,Ors of randomized model and fixed model were calculated tO evaluate the sensitivity.Results There were six RCTs that compared TVT-O with TVT.When compared by Subjective cure,TVT-O at 1-17 months were no better than TVT(OR 0.67;95% CI 0.40,1.13).Adverse events such as bladder injuries (OR 0.15;95% CI 0.03,0.66)was less common,where as groin/thigh pain(OR 8.61;95% CI3.03,24.52)was more common;but there were rio significant difference in de novo urgency(OR=1.16;95% CI 0.54,2.47),urinary retention(OR=0.54;95% CI 0.24,1.20)or urinary tract infection(OR=1.07;95% CI 0.61,1.87)between the tWO groups.Conclusions There is no significant difference between TVT and TVT-O.TVT-O group had no bladder injuries complications,but groin/thigh pain was more common.

Objective To investigate the expression of sphingosine kinase 1(SphK1)and NF-κB in colon carcinoma tissues and their correlation with clinicopathologic features.Methods Sixty-six paraffinembedded colon carcinoma samples and 66 fresh colon carcinoma samples were tested using immunohistochemistry,RT-PCR and Western blot,respectively.Results In 66 fresh colon carcinoma samples,the positive rate of SphK1 and NF-κB mRNA expression were 84.85%(56/66)and 74.24%(49/66),while the positive rate of SphK1 and NF-κB protein detected by Western blot were 78.79%(52/66)and 69.70%(46/66).The positive rates were higher than those in the adjacent tissues[mRNA:63.64%(42/66),48.49%(32/66);protein:57.58%(38/66),45.45%(30/66)]and the normal mucosa [mRNA:42.42%(28/66),25.76%(17/66); protein:36.36%(24/66),24.24%(16/66)],with statistical significances(all P values < 0.05).The mean expressive levels of SphK1 and NF-kB mRNA and protein in colon carcinoma were both significantly higher than those in the adjacent tissues and the normal mucosa(mRNA:0.55±0.06 vs0.35 ±0.05 vs0.25±0.05,0.75 ±0.06 vs0.43±0.05 vs0.30±0.04 ; protein:0.77 ± 0.05 vs 0.38 ± 0.06 vs 0.12 ± 0.03,0.45 ± 0.08 vs 0.23 ± 0.05 vs 0.13 ± 0.03 ;all P values < 0.05).There was a close correlation between SphK1 and NF-kB expression levels (r =0.459,P =0.036).The results of immunohistochemistry were similar to those of RT-PCR and Western blot.Overexpression of SphK1 and NF-κB in colon carcinoma was related with depth of invasion,distant and lymph node metastasis and Dukes'stages(all P values <0.05).The expression of SphK1 was also related with differentiation(P < 0.05).Conclusions Overexpression of SphK1 and NF-κB may be involved in the pathogenesis and progression of colon carcinoma.Moreover,SphK1 and NF-κB may be correlated with the invasion and metastasis of colon carcinoma.

The lateral hypothalamic area (LHA) plays a pivotal role in regulating consciousness transition, in which orexinergic neurons, GABAergic neurons, and melanin-concentrating hormone neurons are involved. Glutamatergic neurons have a large population in the LHA, but their anesthesia-related effect has not been explored. Here, we found that genetic ablation of LHA glutamatergic neurons shortened the induction time and prolonged the recovery time of isoflurane anesthesia in mice. In contrast, chemogenetic activation of LHA glutamatergic neurons increased the time to anesthesia and decreased the time to recovery. Optogenetic activation of LHA glutamatergic neurons during the maintenance of anesthesia reduced the burst suppression pattern of the electroencephalogram (EEG) and shifted EEG features to an arousal pattern. Photostimulation of LHA glutamatergic projections to the lateral habenula (LHb) also facilitated the emergence from anesthesia and the transition of anesthesia depth to a lighter level. Collectively, LHA glutamatergic neurons and their projections to the LHb regulate anesthetic potency and EEG features.
