Objective To explore the possibility of early definitive operation for enteric fistulas. Methods In 37 selected enterocutaneous fistula patients, early definitive operation was performed during laparotomy for treating peritonitis within 10 days of fistula formation. Thorough irrigation of peritoneal cavity, effective sump drainage, fibrin glue sealant to reinforce anastomosis, appropriate nutritional support, and administration of growth hormone were key elements of perioperative management. Results Among 37 patients, 35 of them recovered uneventfully. Fistula recurred in 2 cases postoperatively; one fistula closed after conservative management, and another patient died of advanced gastric cancer 3 months postoperatively. The fistula operative closure rate was 94.5%. No operative death. Conclusion Advances in perioperative management can promote the success rate of early definitive operation for enteric fistulas. It may become a challenge to the present strategy of enteric fistula management.

Objective To explore the relationship of the ADAM33 gene Q-1,T2 single nucleotide polymorphism (SNP) and suffering from chronic obstructive pulmonary disease (COPD) in Xinjiang Kazakh and Han population. Methods Peripheral blood samples to extract DNA, and the single nucleotide polymorphisms of Q-1 and T2 in ADAM33 gene were detected by SNaPshot SNP genotyping. Results Case group compared with the control group, frequencies of Q-1 locus genotypes and alleles were significant differences in Kazak (P<0.05). In patient group, there were significant differences in ADAM33 gene Q-1 locus genotypes FEV1% predicted, FEV1/FVC of clinical indicators lung function in Kazak, Han(P < 0.05). Kazak Q-1 locus AA genotype,Han GA genotype than GG genotype were significant difference.Compare Kazak AA genotype,Han GA genotype with GG genotype is more likely to cause COPD in Q-1 locus(P<0.05). In the comparison of the case and control group the two ethnic, there was no significant difference between the frequencies of T2 locus genotypes and the frequencies of Q-1,T2 the alleles (P > 0.05). There were no significant differences in T2 locus genotypes and clinical indicators of lung function FEV1% predicted and FEV1/FVC in patient group (P > 0.05). Conclusion The ADAM33 gene Q-1 locus may be related to the COPD susceptibility in Xinjiang Kazak, Han.

Objective To evaluate the feasibility and application of histopathology diagnosis of endometrial tissues obtained by endometrial cell collector (Jingyou, SAP-1). Methods One hundred and ninety-three patients whose endometrial lesions should be excluded were selected. First, endometrial tissue were obtained from the patients by Jingyou, then they underwent comprehensive curettage under hysteroscopy. The histopathology diagnosis was performed respectively. The specimen satisfaction rate and diagnostic accuracy was analyzed and compared. Results The specimen satisfaction rate of curettage under hysteroscopy was 95.85%(185/193). The specimens of 8 cases were not satisfied because the tissues were not enough. The specimen satisfaction rate of Jingyou was 82.38% (159/193). The specimens of 34 cases were not satisfied, among whom in 10 cases scratches did not throughout the whole palace antrum, and in 24 cases tissues quality were poor. The endometrial thickness in unsatisfactory specimen by Jinyou was significantly thinner than that in satisfactory specimen:(0.64 ± 0.18) cm vs. (0.97 ± 0.43) cm, and there was statistical difference (P<0.05). The diagnostic accordance rate between Jingyou and curettage under hysteroscopy was 79.87%(127/159). The sensitivity of Jingyou from high to low was 94.19% (81/86) in normal menstrual endometrial, 7/10 in endometrial carcinoma/ atypical hyperplasia, 67.86%(38/56) in endometrial hyperplasia and 1/7 in endometrial polyps. Missed diagnosis of jingyou inluded 2 cases of endometrial carcinoma and 4 cases of endometrial atypical hyperplasia. The misdiagnosed rate of high grade endometrial lesions was 6/16, and the patients were misdiagnosed because the tissues were not enough. Four cases of endometrial atypical hyperplasia had underwent conservative treatment of repeated curettage. Conclusions Application of Jingyou can obtain micro endometrial tissues, and the accordance rate of histopathology diagnosis is high with curettage under hysteroscopy. When the collector makes a comprehensive collection to the uterine cavity specimen, it can accurately screen endometrial carcinoma and atypical hyperplasia. The patients who have endometrial atypical hyperplasia and receive conservative treatment and curettage repeatedly curettage, thin endometrium and ultrasonic highly suspected endometrial polyps, are not recommend to use Jingyou to obtain specimen. When the specimen is not satisfied using the collector, additional hysteroscopy should be performed to avoid misdiagnosis of high grade endometrial lesions.

Anti-bFGF antibody is thought to be an major important reagent for bFGF research. This review summarizes the development of anti-bFGF antibody in recent years including preparation, screening, identification and application in order to provide reference to the studies of this field in our country.

Objective To evaluate pericardial devascularization with splenectomy (PCDV) for the treatment of cirrhotic portal hypertension. Methods From January 1994 to December 2004, 177 patients were treated by PCDS, among them posthepatitic cirrhosis was identified in 170 cases, and alcoholic cirrhosis in 7. One hundred and thirty two patients were operated on electively, 25 prophylactically, and 20 emergently. Results The bleeding control rate was 95% , the overall operative mortality rate was 4. 5%. The main causes of death were upper gastrointestinal bleeding, hepatic failure and intra-abdomimal hemorrhage. The mean follow-up time was 3. 6 years. The 5-year survival rate was 90%. The 5-year recurrent bleeding rate was 5. 1% , The rate of postoperative hepatic encephalopathy was 5. 1%. Conclusions This procedure has the advantage of high successful rate of bleeding control, low complication rate, and long term survival.

AIM: To study the effects of nuclear factor-kappa B decoy oligodeoxynucleotides on generation of nitric oxide and activated oxygen in lipopolysaccharide-induced mouse macrophages.METHODS: Mouse macrophage cell lines J774.1 cells were cultured with lipopolysaccharide and liposome-mediated oligodeoxynucleotides, and the level of nitric oxide, activated oxygen and inducible nitric oxide synthase were measured. RESULTS: Nuclear factor-kappa B “decoy”oligodeoxynucleotides decreased the activity of inducible nitric oxide synthase in lipopolysaccharide-induced macrophage, inhibited generation of nitric oxide and reactive oxygen species. The level of nitric oxide, activated oxygen and inducible nitric oxide synthase did not change in control group.CONCLUSION: Nuclear factor-kappa B “decoy”oligodeoxynucleotides decrease the generation of nitric oxide and activated oxygen in lipopolysaccharide-induced macrophages, which is probably due to inhibiting the binding sites of activated nuclear factor-kappa B specially.

Wnt signals widely exist in live creatures,involved in many physical or pathological processes,including the cell prolif-eration, differentiation and apoptosis. Recent studies show that Wnt/β-catenin signaling pathway may play an important regula-tory role in the protective effects of neurovascular unit in ische-mic stroke. Some chemicals,such as sulindac and estradiol,and some compound traditional Chinese medicine which contains gly-coside( e. g. rhodiola rosea ) , volatile oil ( e. g. turmeric ) and compound prescription ( e. g. Dan Long Xing Nao Fang ) can protect the neurovascular unit by regulating the pathway. This aims to review the research progress of the protective effects of Wnt/β-catenin signaling pathway on the neurovascular unit in is-chemic stroke,with combination of chemicals and traditional Chi-nese medicine which can protect the neurovascular unit via Wnt/β-catenin signaling pathway. It aims to provide the methodology basis for elucidating the mechanism of drugs,and also provide a new idea for researching the new drug which can reduce the dis-ability rate caused by sequela of stroke.
