The biomarkers currently known for the early diagnosis of liver diseases often have poor sensitivities and specificities,and thus it is very important to find new biomarkers with high sensitivities and specificities for the early diagnosis of liver diseases.The emerging metabolomics technology has been widely used and may help to achieve this goal.This article reviewsthe research advances in the role of metabolomics based on ultra-performance liquid chromatography-mass spectrometry in the identification of biomarkers for liver diseases and emphasizes its significance in the early diagnosis,treatment,and prognosis evaluation of liver diseases.

To explore the effect of quercetin on the proliferation and apoptosis of HeLa cells, HeLa cells were incubated with quercetin at different concentrations. Cell viability was evaluated by MTT assay, cell apoptosis was detected by Annexin-V/PI double labeled cytometry and DNA ladder assay. Cell cycle was flow cytometrically determined and the morphological changes of the cells were observed under a fluorescence microscope after Hoechst 33258 staining and the apoptosis-related proteins in the HeLa cells were assessed by Western blotting. The results showed that quercetin significantly inhibited the growth of HeLa cells and induced obvious apoptosis in vitro in a time- and dose-dependent manner. Moreover, quercetin induced apoptosis of HeLa cells in cell cycle-dependent manner because quercetin could induce arrest of HeLa cells at G0/G1 phase. Quercetin treatment down-regulated the expression of the PI3K and p-Akt. In addition, quercetin could down-regulate expression of bcl-2, up-regulate Bax, but exerted no effect on the overall expression of Akt. We are led to conclude that quercetin induces apoptosis via PI3k/Akt pathways, and quercetin has potential to be used as an anti-tumor agent against human cervix cancer.

Objective To study application effectiveness of different concentrations of chlorhexidine oral care solu-tion in patients with orotracheal intubation.Methods A total of 120 patients who were admitted to the general in-tensive care unit (ICU)of a hospital and undergoing mechanical ventilation via orotracheal intubation for >48 hours between January 2012 and December 2013 were included in the study,they were divided randomly into three groups,40 in each group.Trial group,control group I,and control group II were provided with 2%,0.2%,and 0.12% chlorhexidine oral care solution,respectively.Differences in halitosis,oral mucosal infection,onset time and incidence of ventilator-associated pneumonia (VAP ) among three groups were observed and compared. Results There were significant difference in incidence of VAP and early-onset VAP between trial group and control group I,trial group and control group II,respectively(both P <0.05 );incidence of VAP in control group II was higher than trial group(47.50% vs 20.00%,P =0.009).Conclusion 2% chlorhexidine oral rinsing and swabbing can effectively reduce incidence of VAP in patients with orotracheal intubation.

Objective To study the effects of treating intracranial hypertension(ICP) with different dosage Mannitol alone or combined with Furosemide.Methods 60 patients with high ICP after all kinds of operations on cranium and brain were divided into 4 groups according to the dosage of Mannitol alone or combined with Furosemide: 0.5 g/kg Mannitol(group A),1.0 g/kg Mannitol(group B),0.5 g/kg Mannitol and 20 mg Furosemide(group C),1.0 g/kg Mannitol and 20 mg Furosemide(group D).The effective power,rebound ratio,average effective time,average amplitude of decreasing ICP,plasma osmolarity and renal function were evaluated by monitoring intracranial pressure.Results In response of the effective power,rebound ratio of ICP and average effective time,groups C and D were more noticeable than groups A and B(all(P

Objective To study the preventive effect of recombinant streptokinase (r-SK) on cerebral vasospasm (CVS) after subarachnoid hemorrhage(SAH).Methods Rabbit models of SAH were made by double blood injection into cisterna magna. A tube was inserted into lateral ventricle after 24 h. In group treating one, 1.25 mg r-SK were injected into lateral ventricle, and the tube was opened for drainage after closed 6 h, and then 6 h later, injection, closed pipe and drainage were recycled for another 2 times. In the group SAH , 1 ml normal saline (NS) was injected into lateral ventricle, and then the way was the same as group treating one. In group treating two, 3.75 mg r-SK were injected for once. 6 h, 12 h ,1 d, 3 d, 5 d and 7 d later, 1 ml CSF was drained from the lateral ventricle in groups SAH , treating one and treating two ,respectively. The level of OxyHb in CSF was detected, angiograms of basilar artery(BA) were performed before and after 7 d of SAH,calculation the rate of calibre and histological examinations were also performed. Results (1)The level of OxyHb in CSF of group SAH was increased gradually while decreased in groups treating one and treating two. Compared with group SAH, the levels of OxyHb were significant lower in groups treating one and treating two at 1～7 d after administration(P

Clinics in the Olympic venues make a critical component in the medical service system for Olympic venues. The clinic in the fencing hall is cited as an example in this paper, which introduced the experiences and lessons learnt from the site preparation, personnel deployment and management, rules and regulations, and drug/instrumentation readiness.
