Objective To study pathological diagnostic value of forceps and brush biopsy cytological examination by percutaneous transhepatic cholangiodrainage(PTCD) for malignant obstructive jaundice.Methods From April 2005 to April 2006,24 cases of obstructive jaundice underwent PTCD and stent insertion in biliary tract.Tissue pathological examination by forceps and brush was done during PTCD.Results 24 cases received forceps biopsy,of whom,14 cases received brush cytological examination at the same time.All of the 24 cases of forceps biopsy obtained pathological tissue and the pathological results as follows: adencarcinoma in 15 cases,4 cases had allotype cells,regarded as positive results;inflammation tissue in 1 case,which was restenosis after stent insertion;fibrous tissue in 1 case;tissue obtained was cholangioepithelia in 3 cases,in which 1 case was diagnosed as lymph node metastasis of peripheral head of pancreas after gastric cancer operation,2 cases were diagnosed as cholangiocarcinoma,the positive rate of forceps biopsy being 79.2%(19/24).4 cases of cytological examinations by brush showed tumor cells in 2 cases,allotype cells in 2 cases,regarded as positive results,the positive rate being 28.6%(4/14),and others were negative results.Conclusions Intracholangio-biopsy by PTCD offers the advantages of simplicity,safety,higher accuracy and less complications.Pathological diagnosis can be obtained at the same time during reducing-jaundice therapy by PTCD.

Objective To investigate the expression of MTSS1 in cholangiocarcinoma tissue and its relationship with the prognosis of patients.Methods The specimens of bile duct of 49 patients with hilar cholangiocarcinoma who received surgical excision at the Eastern Hepatobiliary Surgery Hospital from January 2003 to December 2005 were collected.Tissue microarrays of the 49 samples of hilar cholangiocarcinomas and the 10samples of adjancent normal bile duct epithelial tissue were constructed.The expression of MTSS1 was detected by the immunohistochemical staining.The pcDNA3.1-MTSS1 was transferred into the RBE cells and the abilities of proliferation of REB cells were measured by MTT assay.The patients were followed up via out-patient examination and telephone till May 2012.The measurement data were analyzed using the t test,and the count data were analyzed using the chi-square test,the survival curve was drawn by the Kaplan-Meier method,the survival was analyzed using the Log-rank test,and multivariate analysis was done using the COX regression model.Results The results of immunohistochemical staining showed that the expression rate of MTSS1 was 10/10 in the adjacent normal epithelial tissue of bile duct,while 59.2％ (29/49) in the cholangiocarcinoma tissues.The proliferative rate of cholangiocarcinoma cells transfected with MTSS1 was 1.55 ±0.05,which was significantly lower than 2.32 ±0.08 of cholangiocarcinoma cells without transfection of MTSS1 (t =4.454,P ＜ 0.05).Gender,age,TNM stage,T stage,differentiation,neural invasion and diameter of tumor did not influence the expression of MTSS1 (x2=0.211,3.471,0.507,0.507,0.368,0.882,0.660,P ＜ 0.05),while lymph node metastasis influenced the expression of MTSS1 (x2=10.436,P ＜ 0.05).All the patients were followed up for 1-59 months,and the median time for follow-up was 16 months.The median tumor-free survival time was 17.9 months in patients with positive expression of MTSSI,and 11.3 months of patients with negative expression of MTSS1,with no significant difference (Log-rank value =3.707,P ＞ 0.05).The median survival time was 34.9 months in patients with positive expression of MTSS1,which was significantly longer than 18.7 months of patients with negative expression of MTSS1 (Log-rank value =5.671,P ＜0.05).Multivariate analysis showed that MTSS1 was not the independent risk factor influencing the prognosis of patients (x2 =0.406,P ＞ 0.05).Conclusions The expression of MTSS1 is decreased in cholangiocarcinoma tissue,which negatively correlates with lymph node metastasis.MTSS1 could be used as a biomarker in predicting the prognosis of patients with cholangiocarcinoma.

OJECTIVE To investigate the preventive effect of Fengliao extract on ulcerative colitis of mice. METHODS Using the intestinal propulsion rate experiment and senna induced diarrhea model , the intestinal propulsion rate, diarrhea rate and index of diarrhea were observed. Mice were randomly divided into normal group,model group,mesalazine hydrochloride group and Fengliao extract 11.7, 23.4 and 46.8 g · kg-1 group. The mouse colitis model was induced by 4% dextran sulfate sodium. The mice were administraed once daily for 7 d while the disease activity index(DAI)score was calculated and the activity of tumor necrosis factor α(TNF-α),interleukin-1β(IL-1β), myeloperoxidase(MPO) and content of malondialdehyde(MDA) and nitric monoxide (NO) in colon tissue were determined. RESULTS Fengliao extract 46.8 g · kg-1 inhibited the intestinal propulsion rate(P<0.05),reduced the frequency of diarrhea and the diarrhea index(P<0.05). Results of colitis showed that the body mass of mice in the model group was significantly decreased but the DAI score increased compared with normal group(P<0.05). The activity of MPO and the contents of IL-1β,TNF-α,MDA and NO in colon mucosa were increased(P<0.01). Compared with the model group,Fengliao extract 46.8 g·kg-1 decreased the DAI score(P<0.05)while Fengliao extract 46.8 and 23.4 g · kg-1 reduced MPO activity in colonic mucosa and content of IL-1β,TNF-α,MDA and NO in colonic homogenate(P<0.05). CONCLUSION Fengliao extract can significantly improve the DSS induced colitis in mice,which is probably associated with its antispasmodic and anti-diarrheal effect as well as the reduced release of inflammatory mediators and antioxidants.

Objective To obtain the specific human scFv basic fibroblast growth factor(bFGF)using phage antibody library technology. Methods The library was panned with human recombinant bFGF for 4 rounds. The antigen binding activities of random clones were tested by ELISA in order to select specific antibodies, which were then examined by DNA sequence analysis. Results The positive clone selected from the 104 random clones was able to bind bFGF specifically, while not able to bind other growth factors,such as aFGF, VEGF(vascular endothelial growth factor). By competition ELISA assay we found one clone 44 could inhibit bFGF binding to FGFR1. Conclusion Seven specific human phage antibody against bFGF was obtained by phage display technique, one clone could inhibit bFGF binding to its high affinity receptor FGFR1.

Objective To observe the operation process implementation and the therapeutic effect of interventional therapy for the superior mesenteric artery thrombosis.Methods 21 cases with superior mesenteric arterial thrombosis who had the diagnosis and clinical treatment in our hospital from January 2005 to December 2013 were retrospectively analyzed.Results Among 21 cases,19 cases had obvious risk factors,and their early symptoms and signs were not consistent.The artery angiography showed that 17 cases had superior mesenteric artery thrombosis,2 cases had ileum arterial thrombosis,2 cases had inferior mesenteric arterial thrombosis.All surgeries were performed successfully.The length of hospital stay was 10 14 days with an average of 11 days.After interventional treatment,the symptom of abdominal pain had obvious remission.The follow-up period was 12 to 36 months and no recurrence was found.Conclusions The diagnosis of mesenteric arterial thrombosis is difficult.Mesenteric arterial thrombosis needs the early diagnosis and timely interventional treatment.

BACKGROUND: Embryonic pancreatic tissue is characterized by its abundance, potent in proliferation & differentiation, and minimal immunological rejection. It is widely considered as potential pancreatic endocrinological stem cells resource for treating diabetes mellitus.OBJECTIVE: To investigate the embryonic mouse pancreatic tissue isolation technique and observe the recipients' blood glucose regulatory effects of the grafted embryonic pancreas in an experimental diabetes mellitus mouse model.METHODS: Pancreatic tissue from C57B1/6 mouse embryos at embryonic days 11.5-16.5 was isolated under the stereomicroscope. C57BL/6 mouse models of streptozocin-induced diabetes mellitus were established and then randomly divided into two groups: transplantation group, in which, five pieces of pancreatic tissue of mice at embryonic 16.5 days were transplanted into mouse renal capsule, and sham-operated control group, in which, 0.05 mL RPMI1640 culture medium was injected into mouse renal capsule. When blood glucose level of the transplantation group mouse was≤ 11.2 mmol/L, the endocrine function of embryonic pancreatic tissue transplanted was detected by IPGTT and IPITT methods and then the transplanted graft was removed for observing the blood glucose relapse.RESULTS AND CONCLUSION: Nearly intact pancreatic tissue of mice at embryonic days 11.5-16.5 could be isolated through the use of stereomicroscope. Pancreatic tissue morphology and color of mice ≤ embryonic 12.5 days were difficultly distinguished from adjacent tissue and they could only be isolated carefully according to the relationship with adjacent organs. Pancreatic tissue of mice > embryonic 12.5 days exhibited initial endocrinological tissue morphology mimic white cauliflower. Histological and ELISA examinations showed that embryonic pancreatic tissue could express and secrete insulin and the insulin level was gradually increased with developmental time. Embryonic pancreatic tissue could grow beneath the recipient renal capsule. The insulin and glucagon expression in the post-transplantational pancreatic tissue graft was increased compared with prior to transplantation. These results suggest that pancreatic tissue is a potential stem cell resource for treating the diabetes mellitus.
