Objective To evaluate the safety and feasibility of natural orifice transluminal endoscopic surgery(NOTES)with current available techniques and endoscopic accessories.Methods Transgastric and transvaginal endoscopic abdominal cavity exploration were performed in 6 female pigs.A needle-knife and a ERCP scalpel were used to make an anterior gastric wall incision,and a dilating balloon to expand the passage,through which a therapeutic gastroscope was sent into the abdominal cavity to seek the target organ.Partial liver resection was performed in 2 cases.For incision closure,a clip was applied to the incision orifice or it was just given putting-aside therapy.One week later,the abdominal cavity was examined via vagina.Another week later,it was observed via other incision of the stomach.Four weeks after the operation,the pigs were sacrificed.Adhesion,injury to the organs and closure of the incision were evaluated.Results Transgastric procedures were performed 12 times and transvaginal procedures 6 times.Mean operation time via stomach was 33.4±10.9 min.and that via vagina WaS 10.1±2.5 min.All animals recovered and gained weight after the operation.The incision healed up with no obvious complications.Re-exploration showed adhesion of various degrees,no effusion,or injury to the organs were observed.Ketamine plus propofol achieved satisfactory anesthetic effect with no complications.One of the two animals which underwent liver partial resection died of disphragmatic muscle perforation.Hemarrhage occurred twice,both in the procedures via satisfied.One case developed abdominal abscess.Conclusion It Was feasible and safe to perform NOTES via transgastric and transvaginal approach to the abdominal cavity and liver resection.But development of NOTES specific instruments is essential to the procedure.

We studied Yersinia infection and carriage in shepherd dog on the natural foci of Marmota himalayana plague and investigated the substitution or antagonism relationship among three pathogenic Yersinia in nature,providing a novel approach for prevention and control of plague.Blood sample and rectal swab specimens from shepherd dogs were collected.Rectal swab specimens were detected and isolated for Y.enterocolitican and Y.pseudotuberculosis.IHA was used to measure the positive rate of F1 antibody.Results showed that among 88,94,70 and 64 serum specimens respectively from Akesai,Subei,Sunan,and Tianzhu,IHA positive rates were 31.82％,32.98％,2.86％ and 1.56％ separately.A total of 236 anal swab specimens of shepherd dog were collected,among which one Y.kristensenii strain and 2 non-pathogenic Y.enterocolitica strain were recovered from Akesai and Subei respectively,where plague was violently prevalent in animals.All the results indicate that shepherd dogs in natural foci of M.himalayana plague where plague in animals are prevalent with non-pathogenic Y.enterocolitica,is an evidence of antagonism relationship in three pathogenic Yersinia.

Objective To evaluate the feasibility and efficacy of betadine solution irrigation of gastrointestinal tract for infection prevention during the procedure of natural orifice transluminal endoscopic surgery(NOTES).Methods Twelve female porcine were divided into control group(n =4)to receive lavage with 500 ml normal saline and experimental group(n =8)to undergo lavage with 500 ml normal saline followed by 200 ml betadine solution.Fluid from gastrointestinal tract(5 ml)were collected before and after lavage,and after NOTES for culture.Endoscopy was performed 24 hours after NOTES to observe possible existence of inflammation,ulcer or bleeding.The animals were sacrificed 3 weeks after NOTES to explore intra-peritoneal adhesions,abscesses and other infections.Results One swine died of diaphragmatic injury and the other 11 animals successfully survived for 3 weeks.In trans-gastric approach,the average bacterial load of the fluid was 17.5 x 103 CFU/ml before lavage.In control group,the average bacterial load of the fluid was 2.5 × 103 CFU/ml after lavage and 5.5 × 103 CFU/ml after NOTES,while those in experimental group were 0 CFU/ml and 7.5 CFU/ml,respectively.In trans-colonic approach,the average bacterial load of the fluid before lavage was 76.2 × 103 CFU/ml.In control group,the average bacterial load of the fluid was 19.5 × 103 CFU/ml after lavage and 21 × 103 CFU/ml after NOTES,while those in experimental group were 2.25 × 103 CFU/ml and 1 × 103 CFU/ml,respectively.No inflammation,ulcer or bleeding were observed by endoscopy at 24 hours after NOTES.More adhesion and abscess were found in the control group than in the experimental group.In experimental group with trans-colonic approach,only one case of adhesion was observed.Conclusion It is effective and feasible of using betadine solution irrigation of gastrointestinal tract in infection prevention during the procedure of NOTES.However,further clinical studies assessing the effectiveness and safety are still necessary.

Objective To explore the effect of fat on 1,2-dimethylhydrazine (DMH)-induced colon tumors.Methods A total of 50 7-week-old male Wistar rats were further divided into four groups:standard diet feed control group (n =10),standard diet feed plus DMH-induced tumor group (SDT,n =15),high-fat diet feed control group (n =10) and high-fat diet feed plus DMH-induced tumor group (HFDT,n =15).Rats were killed 18 weeks later,and enzyme-linked immunosorbent assay was used to detect serum triglyeeride,tumor necrosis factor (TNF-α),and colonic TNF-α,interleukin-6.After the intestinal tracts were removed,the location,amount,and size of the tumors were observed.The pathological changes of the tissue sections were observed,and the distributions of TNF-α and Ki-67 in the normal tissues and tumors were detected by immunohistochemistry.Results Upon the completion of the study,the mortality rate of rats was 20.00％ in the SDT group and 26.67％ in the HFDT group,the tumor formation rate was 75.00％ in the SDT group and 81.82％ in the HFDT group,and the tumor-bearing rate was 117％ in the SDT group and 191％ in the HFDT group.No statistical significance difference between the two groups in mortality rate,tumor formation rate (P =0.545) and tumor bearing rate (x2 =1.343,P =0.247).The average tumor volume was significantly different between the standard diet feed control group and high-fat diet feed control group (28.57％ vs 66.67％,P =0.030).Also,the serum triglyceride and TNF-α levels significantly differed between the SDT group and HFDT group [TG (1.39 ± 0.31) mmol/L and TNF-α (124.80 ± 21.69) ng/L in the HFDT group and TG (0.46 ±0.20) mmol/L and TNF-α (85.83 ± 17.45) ng/L in the SDT group] (P =0.000).The expressions of TNF-α,IL-6,and Ki-67 in colonic mucosa were significantly higher in the high-fat diet feed control group than in the standard diet feed control group [TNF-α:(6.22 ± 0.63) ng/g vs (2.33 ± 0.44) ng/g,P=0.020; IL-6:(13.50±0.67) ng/gvs (7.31 ±0.41) ng/g,P=0.000; and Ki-67:40％ vs 10％,P =0.028].The Ki-67 expression rate was 90.48％ in the HFDT group,compared to 50％ in the SDT group (P =0.015).Conclusions High-fat diet can increase the serum triglyceride and TNF-α levels in rats,upregulate the expressions of TNF-α,IL-6 and Ki-67,and thus promote inflammation and cell proliferation,and ultimately affect the tumor formation and development.However,the effect of fat on DMH-induced colon tumors warrants further studies.

Objective To investigate the effect of long-term antiviral treatment on clinical outcome and liver histology in patients with hepatitis B virus ( HBV)-related compensated cirrhosis .Methods A total of 61 patients with HBV-related compensated cirrhosis receiving antiviral therapy were enrolled from Taizhou Hospital of Zhejiang Province during September 2010 and March 2015, including 26 HBeAg-positive cases and 35 HBeAg-negative cases .Thirty-nine patients were treated with entecavir ( ETV ) and 22 were treated with adefovir dipivoxil ( ADV ) .Biochemical , serological and virological markers were examined every 3 months during treatment, and Child-Turcotte-Pugh (CTP) scores were calculated.All the patients underwent liver biopsy before and 144 weeks after antiviral treatment .Metavir scoring system was used to evaluate the liver histological activity ( A) and fibrosis score ( F) .Wilcoxon rank sum test and paired t-test were used for the evaluation of liver histopathology and liver function before and after treatment , respectively.Results After 144 weeks of antiviral treatment , HBV DNA was reduced and below the lower limit of detection in 58 patients (95.1%), HBeAg disappeared in 14 patients (14/26, 53.8%), and HBeAg seroconversion was observed in 10 patients (10/26, 38.5%); alanine aminotransferase ( ALT), aspartate amino transaminase (AST), total bilirubin (TBil) and CTP score decreased (t=7.489, 8.259, 14.000 and 6.026, all P<0.01), prothrombin time (PT) was shortened (t=9.777, P<0.01), and serum albumin (Alb) increased (t=3.446, P<0.01).Improvements in both liver histologic activity and fibrosis score were observed (Z=5.716 and 6.657, all P<0.01).Liver histological activity decreased from A1 to A0 in 16 cases, from A2 to A0 in 9 cases, from A2 to A1 in 15 cases, from A3 to A0 in 1 case, from A3 to A1 in 5 cases, and from A3 to A2 in 5 cases.Fibrosis score at the baseline was F 4 for all patients, while after treatment, there were 7 patients with F1, 22 with F2, 20 with F3, and F4 remained in rest 12 patients.Conclusion Both clinical and histological improvements can be obtained after long-term antiviral treatment for patients with HBV-related compensated cirrhosis .

Hespintor is an unknown function protein that was got from hepatoblastoma cell lines HepG2 by suppression subtractive hybridization technique (SSH), sequence analysis showed that the protein is a new member of secretory type of Kazal type serine protease inhibitor (Serpin) family, and has high homology with esophageal cancer related gene 2 (ECRG2). The coding sequence of Hespintor's Kazal domain was subcloned into prokaryotic expression vector pET-40b(+), then transformed into Rosetta (DE3). A recombinant protein about 42 kDa in the form of inclusion body was optimization expressed by inducing with 0.25 mmol/L IPTG, 30 degrees C for 5 h. and its specificity was confirmed via Western blotting. The recombinant protein was purified by metal chelate affinity chromatography (MCAC) and anion-exchange chromatography. The preliminary experimental result showed that the recombinant protein can inhibit trysin hydrolysis activity specifically. The result clearly demonstrated that Hespintor, as a novel member of Serpin, would be valuable in developing anti-tumor agents.
