Ammonia toxicity has been generally accepted as one of the classic theories of the pathogenesis of hepatic encephalopathy (HE). Ammonia induces changes in neurological system energy metabolism, oxidative stress, mitochondrial permeability transition (MPT), GABA and Glutamatergic neurotransmission, intracellular signal transduction and Aquaporin 4 (AQP4) expression, astrocyte swelling is another important consequence of ammonia neurotoxicity. This article reviewed the role of these factors in the mechanism of HE and ammonia toxicity.

Objective To investigate the association between Metabolic syndrome and colon cancer.Methods A literature search was performed through PubMed,Ovidsp,CNKI and Wangfang Data within the time limit of January 1 990 to May 2014.Ac-cording to the inclusion and exclusion criteria,the studies were screened and the data were extracted.Then Meta-analysis was per-formed using Stata Statistical Software version 12.0.Results A total of 8 studies(6 cohort studies and 2 case-control studies)met the inclusion criteria.Meta analysis showed that patients with Metabolic syndrome had a higher risk of colon cancer incidence com-pared with the control group without Metabolic syndrome(OR =1.43,95%CI :1.23 - 1.66,P <0.05 ).Stratified analysis showed Metabolic syndrome had a higher risk of colon cancer incidence in male(OR=1.50,95%CI :1.22-1.84,P <0.05),but in female, this association was not found(OR=1.39,95%CI :0.98- 1.96,P =0.07).In addition,Meta analysis showed that Metabolic syn-drome was not associated with an increased risk of colon cancer mortality(OR=1.22,95%CI :0.92-1.63,P =0.1 7).Conclusion This Meta analysis indicated a positive association between Metabolic syndrome and colon cancer incidence in male,but not in fe-male.Metabolic syndrome might not be associated with an increased risk of colon cancer mortality,yet it needs more prospective co-hort studies to confirm the conclusion.

Objective To study the correlation of multi-slice CT portography (MSCTP) and digestive endoscopy in the diagnosis and evaluation of esophageal and gastric varices (EGV) caused by cirrhosis.Methods A total of 92 patients with cirrhosis were enrolled in the prospective study.All the patients were examined by endoscopy and 64-slice spiral CT scan in 4 weeks.The types,grading of EGV were observed by endoscopy and MSCTP,and Kappa conformance test was applied with the endoscopic findings as gold standard.The sensitivity,specificity,consistency,and Youden index were evaluated for the diagnosis of sophageal and gastric varices by MSCTP.Results Sixty-five patients were diagnosed to have EGV by endoscopy and 27 were negative.The positive patients included 45 patients of GOV1,19 of GOV2 and 1 patient of IGV1.MSCTP diagnosed 67 cases of EGV and 25 patients of negative results.The positive patients included 46 of GOV1,18 of GOV2 and 3 of IGV1.Two patients of IGV1 varicose veins without positive findings on endoscopy were diagnosed by using MDCTP,which revealed isolated varicose veins under the gastric mucosa.There was high consistency between MSCTP and EGV in the diagnosis of EGV (Kappa =0.732,P ＜ 0.01).The sensitivity of MSCTP was 93.8％,specificity was 77.8％,consistency was 89.1％,and Youden index 71.6％.There was high consistency between MSCTP and EGV in the classification of EGV (Kappa values were 0.743 and 0.763,P ＜ 0.01).Conclusions There is high consistency between MSCTP and digestive endoscopic in the diagnosis and classification of EGV in cirrhosis.MSCTP is superior to endoscopy in the detection of gastric varices.

Objective To estimate the clinical value of thinprep cytologic test (TCT) in screening cervical lesion. Methods 4234 TCT samples were interpreted according to the Besthesda System (TBS), 272positive cases (ASC-US or above) were taken colposcopic examination and biopsy. Results The coincidence of the results between TCT and biopsy in low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL), squamous cell carcinoma (SCC), adenocarcinoma (AC) were 85.71%(12/14), 100 % (20/20), 75 % (3/4) and 100 % (2/2), respectively. The positive rates of over ASC-H by TCT and of over CIN Ⅰ by biopsy were 23.16 % (63/272) and 24.26 % (66/272), respectively. There is no difference between two positive rates (x2 = 0.868, P = 0.581). Conclusion TCT and histopathological diagnosis had a high coincidence, a combination of both can greatly enhance HSIL and cervical cancer and reduce the incidence of missed diagnosis. TCT would be a rapid and convenient method for screening cervical cancer.

Objective To investigate the effects of remote ischemic postconditioning (RIPoC) on global cerebral ischemia-reperfusion (I/R) injury in rats.Methods One hundred and twenty-eight male adult SD rats weighing 200-250 g were randomly divided into 4 groups ( n =32 each):sham operation group (group S),group I/R,group I/R + RIPoC and remote I/R group (group RI/R ).Global cerebral I/R was induced by four-vessel occlusion.Group I/R + RIPoC received 3 cycles of 15 min reperfusion followed by 15 min ischemia in bilateral femoral arteries at the beginning of cerebral reperfusion.The rats were sacrificed at 24 and 48 h of cerebral reperfusion,and brains were removed for determination of neuronal apoptosis (by TUNEL method) in hippocampal CA1 region and the parietal cortex,Bcl-2 and Bax expression (by Western blot) in hippocampal CA1 region.The superoxide dismutase (SOD) and catalase (CAT) activity and malondialdehyde (MDA) content in hippocampal CA1 region and the parietal cortex were also measured at 48 h of cerebral reperfusion.Morris water maze task was used to test the learning and memory function at 4 d of cerebral reperfusion,and the rats were sacrificed at 7 d of cerebral reperfusion,and brains were removed for determination of neuronal density in hippocampal CAl region and the parietal cortex.Results Cerebral I/R significantly increased the number of apoptotic neurons and MDA content,upregulated Bcl-2 and Bax expression,decreased neuronal density,SOD and CAT activity and learning and memory function in group I/R as compared with group S.RIPoC significantly attenuated these cerebral I/R-induced changes.Conclusion RIPoC could protect brain against global cerebral I/R-induced injury,and the mechanism may be related to inhibiting lipid peroxidation,regulating the balance between Bcl-2 and Bax and inhibiting apoptosis.
