Objective To investigate the effect of ethanol on level of the main hippocampal subtype of muscarinic receptor(M1)in mice,and evalu?ate whether the content change on this receptor could be linked with alterations in cognition,so as to further reveal the mechanism of brain damage in?duced by ethanol. Methods Sixty female mice were randomly divided into four groups. The model mice were induced by intragastric administration of ethanol at dose of 8%,16%,and 32%respectively of 0.2 mL/10 g for 8 weeks according to the protocol,and control group were treated with intra?gastric administration of distilled water. The capability of learning and memory were examined by Morris water maze,and ELISA method was used to measure the M1 receptor content in hippocampus in each group of mice. Results Compared with first day,the mean escape latency period on the fifth day was significantly shortened in each group. There was no significant difference between ethanol and control group for the mean escape latency period on the fifth day. Compared with the control group,the active time in the target quadrant was significantly shortened in 16%and 32%ethanol group. M1 receptor content in hippocampus formation was significantly decreased in all the ethanol group mice. The ethanol concentration was nega?tive correlated with the M1 receptor content. Conclusion Chronic alcoholism can induce the memory impairment in mice,which might be associat?ed with the low level of M1 receptor subtype in hippocampus of mice.

Purpose:To investigate the prevention and treatment protocol for Af after resection of esophageal and car- dia carcinoma.Methods:Analyses for clinical materials of 1527 patients underwent resection for esophageal and cardiac carcinoma.Results:There were Af 23 cases.Age older than 60 years,abnormal ECG or/and pulmonary function before operation,gastro-esophageal anastomosis above the aortic arch and histological staging Ⅲ~Ⅳ were risk factors for AF.Fa- tal AF was rarely seen.In our 23 cases after treatment in time AF disappeared.Conclusions:Further recognition for post- operative AF and management of perioperative period complication,may reduce the danger of postoperative AF.

Objective To detect UGT1A1 gene promoter polymorphism with gene sequence method and analyze the distribu-tion of UGT1A1*28 and UGT1A1*6 gene polymorphism in Wuhan.Methods A total of 230 samples were collected from tumor patient in Medical Oncology Department of Renmin Hospital of Wuhan University from January 2013 to December 2014,then gene sequence of the target fragments were detected by Sanger sequencing method and analyzed patient UGT1A1 gene promoter polymorphism TA box.Results In this research examination 230 example tumor patient,198 patients (86.1%)were identified with TA6/TA6 genotype,29 patients (12.6%)were identified with TA6/TA7 genotype,3 pa-tients (1.3%)TA7/TA7 variant.Conclusion TA6/TA6 wild-typewas higher frequence in patients with malignant tumour in Wuhan.

Objective To evaluate the value of contrast-enhanced ultrasound (CEUS) in diagnosing ischemic-type biliary lesion (ITBL) and analyze the relation between the enhancement patterns of bile duct wall of ITBL and its outcome.Methods 36 patients confirmed with ITBL (24 cases),anastomotic biliary stricture (3 cases),cholangitis (4 cases),biliarysludge (1 cases),and acute rejection (4 cases),who underwent CEUS examination,were enrolled in this study.The images were retrospectively analyzed in consensus by 2 readers.After reviewing the images,the readers were asked to make a diagnosis of ITBL.The diagnostic standard was hypo-or non-enhancement of hilar bile duct wall in arterial phase on CEUS.Results The diagnostic sensitivity,specificity,accuracy,positive predictive value and negative predictive value were 66.7%,83.3%,72.2%,88.9%,and 55.6% for reader 1;62.5%,83.3%,69.4%,88.2%,and 52.6 % for reader 2,respectively.The interobserver agreement was good (κ =0.83).In 24 ITBL patients,the ratio of mortality or retransplantation with non enhancing hilar bile duct wall in arterial phase was much higher than that with enhancing hilar bile duct wall (non-enhancement 54.5%,hypo-enhancement 20%,hyper-or iso-enhancement 12.5%).Conclusions CEUS had diagnostic value of ITBL.Non-enhancing hilar bile duct wall in arterial phase on CEUS predicated the poor outcome.

Background and purpose:Promoter methylation ofPCDH10, a gene encoding protocadherin 10, has been found to be correlated to poor prognosis in gastric cancer (GC) patients. However, the relationship between the expression of PCDH10 and prognosis in GC remained unknown. This study aimed to explore the relationship be-tween the expression of PCDH10 and clinicopathological features and prognosis of GC, and to identify biomarker for predictions of recurrence and survival of GC.Methods:mRNA expressions of PCDH10 in 115 pairs of GC tissues and adjacent normal tissues were detected by real-time lfuorescence quantitative polymerase chain reaction (RTFQ-PCR). The correlation between PCDH10 expression level and clinicopathological features and prognosis of GC was analyzed. Prediction models for 5-year recurrence and 5-year survival were established using logistic regression method.Results:Progression-free survival (PFS) and overall survival (OS) were signiifcantly prolonged in patients with PCDH10 low expression compared to patients without PCDH10 low expression (P=0.046 andP=0.033 respectively). PCDH10 low expression signiifcantly correlated with less lymph node metastasis (P=0.001) and earlier TNM staging (P=0.001), and was more common in female than in male (P=0.040). The mRNA expression of PCDH10 did not correlate with age, Lauren classiifcation, T stage, neural invasion or vascular invasion. Univariate Cox analysis showed Lauren classiifca-tion, T stage, N stage, M stage and PCDH10 expression signiifcantly correlated with PFS and OS. Logistic regression models for the prediction of 5-year recurrence or 5-year survival based on clinicopathological features included Lauren classiifcation, T stage, N stage and M stage as variables. Logistic regression models for the prediction of 5-year recur-rence or 5-year survival based on PCDH10 expression included Lauren classiifcation, T stage, M stage and PCDH10 expression level but not N stage as variables. The models based on PCDH10 expression had the same effciencies as models based on clinical parameters in predicting 5-year recurrence or 5-year survival for GC patients.Conclusion:PCDH10 low expression correlated with better prognosis, less lymph node metastasis and earlier TNM stage in GC patients. Low expression of PCDH10 may be a biomarker of better survival for GC patients. Logistic regression model based on PCDH10 mRNA expression may serve as a prediction model when patients have unknown lymph node metas-tasis status.
