Objective To compare the efficacy of liver preservation in SX-1 solution,HC-A solution and UW solution in the two-cuff technique orthotopic liver transplantation model in rats.Methods We confected SX-1 solution using of aseptic technique and built up two-cuff technique orthotopie liver transplantation model in rats.The SX-1 solution,UW solution and HC-A solution preserved rats livers in 2 h,8 h and 24 h,then went orthotopic liver transplantation.The various hepatic indices were determined when the rats survived for 6 hours after the operation.Results For the ALT,AST,the SX-1 solution group(2 h,8 h,24 h)and UW solution group went up synchronously,there was no statistical significance,(P＞0.05).Compared with HC-A solution group the SX-1 solution group (2 h,8 h,24 h)has already shown the statistical signifcance(P＜0.05).For the LDH,the SX-1 solution group (2 h,8 h,24 h)and HC-A solution group went up synchronously,there was no statistical significance(P＞0.05).Compared with UW solution group the SX-1 solution group(2 h,8 h,24 h)has already shown the statistical significance(P＜0.05).For the number of liver with bile production,each group didn1 show the statistical significance (P＜0.05).The time of preserving liver increased with the number of liver with bile production reducing.Conclusions Confirmed by the orthotopie liver transplantation model in rat,the SX-1 solution is the same as the UW solution in the indices of hepatic enzymologists.exceeding the HC-A solution.The SX-1 solution is the same as HC-A solution and UW solution in the number of liver with bile production.

Objective: To evaluate the diagnosis, treatment and prognosis of patients with synchronous primary endometrial and fallopian tube cancers. Methods: The clinical records of four cases of synchronous primary endometrial and fallopian tube cancers from Jiangxi Maternal and Child Health Hospital between October 2008 and October 2013 were reviewed. The follow-up was performed in all patients. The date of last contact was June 30, 2014. Results: The preoperative diagnosis for four cases was endometrial cancer. Two of them underwent extensive abdominal hysterectomy, bilateral salpingo-oophorectomy, pelvic lymphadenectomy and para-aortic lymph node biopsy, and the other two cases underwent extrafascial abdominal hysterectomy, bilateral salpingo-oophorectomy, pelvic lymphadenectomy and para-aortic lymph node biopsy. The postoperative diagnosis for four cases was stage IA endometrioid adenocarcinoma and stage IA/IB fallopian tube adenocarcinoma. Three patients received 1-3 cycles of chemotherapy of docetaxel plus platinum, and one patient didn't receive any chemotherapy. The follow-up time was 38-71 months. All patinets remained tumor-free survival by June 30, 2014. Conclusion: The patients with synchronous primary stage I endometrial cancer and stage I fallopian tube cancer has a good prognosis, and the extensive/extrafascial abdominal hysterectomy, bilateral salpingo-oophorectomy, pelvic lymphadenectomy and para-aortic lymph node biopsy are appropriate surgical procedures for these patients. The necessity of postoperative chemotherapy should be further explored.

Objective:To study the function and mechanism of miR-30a in rat cerebral ischemia-reperfusion (I/R) injury.Methods:The middle cerebral artery occlusion (MCAO) model was established by intravascular suture method, and the expression of miR-30a in brain tissue was detected by real-time quantitative polymerase chain reaction (qRT-PCR). After intracerebroventricular injection of miR-30a lentivirus, the infarct area was detected by 2, 3, 5-triphenyltetrazole chloride (TTC) staining, the neurological deficit was detected by Bederson method, and the concentration of neurotrophin-3 (3-NT) and nitric oxide (NO) in brain tissue was detected by enzyme-linked immunosorbent assay (ELISA). The protein levels of kelch like ECH associated protein 1 (Keap1), NF-E2-related factor 2 (Nrf-2) and hemeoxygenase-1 (HO-1) in brain tissue were detected by Western blot. Double luciferase reporter assay was used to detect the targeting relationship between miR-30a and Keap1.Results:Compared with sham operation group, the expression of miR-30a was down-regulated in a time-dependent manner after I/R. The overexpression of miR-30a can reduce the area of cerebral infarction tissue at the pathological level, the degree of neurological impairment at the functional level, the 3-NT, NO and Keap1 at the molecular level, and enhance the expression of Nrf2 and HO-1. The dual luciferase reporter assay also showed that miR-30a could bind to Keap1 mRNA.Conclusions:The expression of miR-30a was down-regulated in MCAO rat brain tissue, and miR-30a could attenuate cerebral I/R injury in rats by targeting Keap1.

Objective To determine the expression of serum proteins in pancreatic cancer patients based on mass spectrometry to screen differential proteins and to find potential molecular biomarkers to prediagnosis of pancreatic cancer. Methods The technique of isobaric tags for relative and absolute quantitation (iTRAQ) and two-dimensional liquid chromatography-tandem mass spectrometry (2D-LC-MS/MS) were used to analyze the serum proteins in 15 pancreatic cancer patients and 10 healthy controls. Screening for serum differential proteins was performed via retrieving Panther, Mascot and Scaffold databases. Ingenuity Pathway Analysis was used to detect the correlation between proteins. Results The expression level of 442 proteins was quantified, and 76 proteins were found to be differentially expressed which changed corresponding biological process. The up-regulation of DNA repair protein 50 (RAD50) and down-regulation of transforming growth factor β1 (TGFβ1) and apoptosis protease-activating factor 1 (APAF1) which were correlated with cell growth and apoptosis were found in pancreatic cancer. A closely interacted network was formed between these three differential proteins and other molecules, which could effect metabolism in pancreatic cancer patients. Conclusion Differential expression of serum proteins screened by iTRAQ in pancreatic cancer patients may be the potential markers of pancreatic cancer, which can provide molecular basis for early diagnosis of pancreatic cancer.

Cardiovascular disease is a major cause of morbidity and mortality in the contemporary society. Cardiac gene therapy has already been investigated in clinical studies profoundly. Adenovirus vector could transfer the gene efficiently, but low organ specificity and immuno- genie properties limited its application, With adenovims vector improved in the last few years, the third adenovims vector is probably the most potential vector systems for cardiovascular disease. This review will give a broad overview of the molecular basis of the adenovims vectors, their advantages, the development of increasingly efficient gene transfer approach, and experimental and clinical studies targeting the heart, application barriers and modified strategies.

Objective To investigate the accuracy of liver volume measurement in patients with primary hepatocellular carcinoma by using the 3D + medical imaging visualization processing system. Methods Thirty patients who were clinically diagnosed as primary hepatocellular carcinoma and underwent surgical resection before preoperative assessment were selected from January 2016 to November 2016. Preoperative thin-slice CT images were transferred into the 3D + medical imaging visualization processing system for hepatic volume measurement, the predictive resection volume were measured and statistically analyzed with that of intraoperative specimen according to water measurement method. Results All patients had complete resection of tumor, the average volume of predictive resection calculated by the 3D software was (408.84 ± 177.07) ml, the average volume of intraoperative specimen measured by the water test was (399.95 ± 176.15) ml, the difference was not statistically significant (t=1.502, P=0.144), and the average percentage error was (6.21 ± 4.73) %. Pearson correlation analysis showed that there was significant correlation between them (r=0.983, P<0.05). Conclusion 3D+medical image visualization processing system is a simple, intuitive and accurate method for liver volume measurement, which can provide the basis for the accurate measurement of liver volume and the implementation of complex hepatectomy, and guide the precise hepatectomy.

Usually the survival period of patients with duodenal obstruction caused by inoperable advanced pancreatic cancer is rather short. For such patients, minimally invasive treatment should be employed as the first choice. This paper reported a case with advanced pancreatic cancer complicated by biliary and duodenal obstruction. After implantation of biliary stent, the obstructive jaundice was relieved. Because of the insufficient cardiac function, the patient was not able to tolerate gastrojejuostomy; besides, as both DSA-guided stent implantation and endoscopic nutrition tube placement failed to success, implantation of nutrition tube via the trans-hepatic and biliary route, as a novel tube placement technique, had to be carried out, and the result in this case was satisfactory.
