Objective To establish a rapid,sensitive and specific assay based on real-time PCR combined with reverse transcription for detecting and identifying viable Listeria monocytogenes.Methods The hlyA gene of Listeria monocytogenes was chosen as target,and then the primers and TaqMan probe were designed.Both ends of probe were modified with two different fluorescence groups.The PCR reaction was optimized systematically.The mRNA of Listeria monocytogenes was extracted,and then reverse transcription was performed through random primer.The cDNA Was detected by real-time PCR.Then the specificity,sensitivity and reproducibility of real-time PCR were estimated.In final,real-time PCR was applied to detect 20 mocked double-blind samplea.Results Viable Listeria monocytogenes were detected by real-time PCR accurately and quickly,and meanwhile,none of other bacteria and non-viable Listeria monocytogenes could be identified.The sensitivity was 10 CFU/ml in pure culture and 103CFU/ml for mocked samples respectively.The coefficient of variation of intra-assay and inter-assay Was less than 5%.When this assay was applied directly to identify 20 mocked double-blind samples,10 of these were positive to viable Listeria monocytogenes,5 were negative to non-viable Listeria monocytogenes,and 5 were negative to other pathogens.Conclusion It is demonstrated that real-time PCR is a reliable,accurate and feasible assay for viable Listeria monocytogenes.The establishment of this assay provided complete data for analysis and diagnosis in the field of food safety and epidemiologic survey.

TcdA and B toxins secreted by Clostridium difficile( CD) are two important causes of diseases in organisms. The expression of tcdA and tcdB genes is regulated by a few factors located in the pathogenicity locus ( PaLoc) .Studies have indicated that the tcdC gene is likely to act as a negative regulator of toxin gene expression.So far, it has been debatable whether tcdC gene is regarded as a negative regulator.The mechanism of tcdC gene in pathogenesis remains unclear.In this paper, the structure and function of the tcdC gene are summarized, which will help study the mechanism of tcdC gene and obtain optimal drug targets.

Objective To probe the indication of biliary tract reconstruction without T-tube in orthotopic liver transplantation.Methods We put forward indications of biliary tract reconstruction without T-tube in orthotopic liver transplantation since January 2004 and there were 102 patients who underwent liver transplantation in our hospital without a T-tube in place after biliary tract reconstruction.The incidence of biliary tract complication was observed in these patients.Results All patients were followed up for more than 6 months.The incidence of biliary tract complication was 4.9 percent(5/102)in this group with 3 patients of intrahepatic difluse bile duct stenosis necessitating liver re-transplantation.The other 2 patients with common hepatic duct nonanastomotic stenosis were healed by ERCP plus stent placement.Conclusions Biliary tract reconstruction without T-tube placement helps to decrease the incidence of biliary tract complications resulting from the T-tube removal.

Objective To evaluate the clinical value of noninvasive positive-pressure ventilation (NPPV) treatment in acute respiratory distress syndrome caused by acute pancreatitis. Methods A retrospective study of 27 cases, with acute respiratory distress syndrome (ARDS) caused by acute paucreatitis,who were admitted to our department from Jan 2007 to May 2010 and treated with NPPV, was performed. The changes of heart rate, respiratory rate, PaO2, oxygenation index (OI) and PaCO2 before and after treatment were compared. Results The heart rate, respiratory rate of 25(92.6％ ) patients decreased from (118.4 ±13.4)/min, (32.1 ± 1.7)/min to ( 81.9 + 8.5 )/min, ( 19.9 ± 2.1 )/min; PaO2, OI and PaCO2 increased from (74.1 ±5.0)mmHg, (148.2 +10.0)mmHg, (28.7 ±1.6)mmHg to (110.4 ±20.8)mmHg, (204.5±71.1)mmHg, (38.4 +3.6)mmHg 48 h after NPPV, respectively, and they recovered and were transited to oxygen supply by Venturi mask. 2 (7.4％) patients deteriorated and were transited to invasive positive-pressure ventilation support. Conclusions NPPV could effectively improve oxygenation of patients with ARDS caused by acute pancreatitis. The procedure of NPPV is relatively easy to use and to learn with few complications, and worth of clinical application.

ObjectiveTo determine the risk factors and the optimal management of hepatic artery complications (HAC) after orthotopic liver transplantation.MethodsThe clinical data of 180 orthotopic liver transplantation patients performed between January 2005 and September 2007 was reviewed.The incidence of HAC between primary liver carcinoma and benign diseases of liver was compared.ResultsTwelve (6.7％) episodes of HAC were identified.3 were hepatic artery thrombosis (HAT) and 9 were hepatic artery stenosis (HAS).The incidence of HAC in patients with primary liver carcinoma (6/39) was higher than benign disease (6/141)(P＜0.05).ConclusionsThe keys to management of HAC after orthotopic liver transplantation are to diagnose the complication in time and to select the proper treatment based on the type of HAC.

Objective To evaluate the clinical value of laparoscopic cystogastrostomy for retrogastric pancreatic pseudocysts.Methods Five patients suffering from retrogastric pancreatic pseudocysts caused by severe acute biliary pancreatitis received conservative management for 2 ～ 6 months,and the sizes of pseudocysts were 8,10,12,14,15 cm.All the 5 patients received laparoscopic cystogastrostomy,and 4 ports methods was applied,through anterior gastric wall,the posterior gastric wall and pancreatic pseudocysts were incised by using harmonic scalpel,then cystogastrostomy was performed to drain the pseudocysts.Results Laparoscopic cystogastrostomy for retrogastric pancreatic pseudocysts was successful in all patients,theoperation time was 90,105,115,120,150 minutes.The blood loss was 100,150,150,200,300 ml.No intra-gastric bleeding occurred.After 1 month follow-up,all the pseudocysts disappeared,and there was no acute pancreatitis and local infection recurrence.Gastric leakage occurred 7 d after operation in one patient,and was healed after one month of conservative management.Conclusions Laparoscopic cystogastrostomy through gastric cavity for retrogastric pancreatic pseudocysts is simple and effective,mini-invasive,and it can be an alternative therapeutic method for pancreatic pseudocysts.

ObjectiveTo analyse the clinical characteristics of pancreatic intraductal papillary mucinous neoplasm (IPMN) which coexists with extrapancreatic malignancy (EPM),with an aim to provide strategies for clinical diagnosis and treatment.MethodsThe PubMed was used to search for the pancreatic IPMN related articles with positive pathologic results.A pooled analysis was then performed.The ratio ofpancreatic IPMNs coexisting with EPMs and the locations (or the type) of EPMs were analyzed.ResultsAfter a strict process of screening,18 articles met the pre-determined standardsand were accepted.Of the 1327 patients,363 had coexisting EPMs (27.35％).There were 392 EPMs in these 363 patients.The EPMs occurred in almost all the systems of the body,especially in the digestive tract and its related organs,which accounted for 63.06％ of the EPMs. Conclusions There is a tendency for patients with pancreatic IPMN to have coexisting EPM. More than half of these EPMs are malignant tumors in the digestive system. When pancreatic IPMN is diagnosed,the clinician should be aware of the possible coexistence of an EPM and should look for the possibility of a new EPM developing in a patient after treatment of pancreatic IPMN.
