BACKGROUND:The biological extracellular matrix materials become the focus of pelvic floor repair materials research because of its excellent biocompatibility and mechanical compatibility. However, bacterial infection can damage the function of biological repair materials. ＜br> OBJECTIVE:To prepare the biologic antimicrobial materials for pelvic tissue function repair. ＜br> METHODS:Chitosan and tigecycline-loaded chitosan nanoparticles suspension was prepared by the electrostatic adsorption and self-aggregation of nanoparticles preparation techniques. Then the suspension was coated onto the surface of extracellular matrix materials. The morphological examination was performed by scanning electron microscope. The antibacterial property was detected by solid plate microbial culture method. ＜br> RESULTS AND CONCLUSION:Infrared spectra displayed that aromatic ring skeleton vibration peak of chitosan occurred on the biologic antimicrobial materials, and it was significantly widened at about 3 359 cm-1, indicating the composite coating was successful to modify the surface of extracellular matrix materials. As a very smal dose of tigecycline, there was no characteristic absorption peak on the infrared spectra. Scanning electron microscopy showed the porous structure of the material surface with some nanoparticles adhesion. The prepared materials had good antibacterial properties on Staphylococcus aureus and Escherichia coli, and the inhibition zone diameter was significantly increased with the increasing concentration of antibacterial agent. The biologic antimicrobial materials for pelvic tissue function repair were prepared successful y.

Objective To study the tactics, methods and relevant factors of transcatheter embolization for acute gastrointestinal hemorrhage.Methods Fifteen patients with acute gastrointestinal hemorrhage were embolized by one of the methods of Polyvinyl Alcohol (PVA), gelfoam or metal coils. Four of the fifteen patients were upper gastrointestinal hemorrhage, the other cases were lower gastrointestinal hemorrhage which were embolized using coaxial microcatheter. Results Fourteen of the fifteen patients were treated successfully by these methods. There were total 17 times of embolization for 16 parts, the success rate reached 94.1%. The other one reveaded an infarction of intestine after the embolization and was cured by resection. One of the fifteen patients appeared a recurrent hemorrhage 3 months later, and confirmed to be a hemangiolymphangioma. Two patients with malignant tumor were operated upon selectively. The other patient of intestinal hemorrhage was embolized successfully by using a metal coil after shock. Leiomyoma complicated with large area of bleeding was finally proven by operation.Conclusions Transcatheter embolization for acute massive gastrointestinal hemorrhage is safe and efficient under different choice of methods. The key of success is the right selection of embolized target artery and dosage of emboli.

Objective To discuss the relevance between vitreopapillary traction (VPT) and anterior ischemic optic neu?ropathy (AION). Methods Two patients suffering from AION were underwent routine ophthalmic examination, and visual field (VF), fundus fluorescence angiography (FFA) and optical coherence tomography (OCT) examination. The images were analyzed. Results VPT syndrome was observed by OCT in both cases. In addition, the affected parts of VPT were consis?tent to that of AION. Conclusion Vitreopapillary traction is a possible reason of anterior ischemic optic neuropathy.

Objective To study a new operative method for treatment of hepatic venous occlasion without (associated) pathologic change of inferior vena cava or long-segment stricture. Methods A total of 44 cases of Budd-chiari syndrome with hepatic venous occlusion without pathologic change or long-segment stricture of (inferior) vena cava underwent combined mesocaval C-shunt, ligation of splenic artery, and esophagogastric (devascularization).Results Pre-shunt portal venous pressure was 36cmH2O(31~45 cmH2O, 1cmH2O=0.0098kPa) and post-shunt pressure fell to 26 cmH2O(21~33 cmH2O),the mean reduction was 10 cmH2O. One patient died of liver failure. A slight degree of hepatic encephalopathy occurred in 2patients who recovered after conservative treatment.Chylorrhea occurred in 4 patients, and it spontaneously disappeared 7d to 3.5months after operation. 39 patients(88.6% follow up) were followed up for 6months to 7years , and there was no case of recurrent bleeding nor hepatic encephalopathy. Ascites disappeared in 31cases,and was markedly reduced in 7 cases .The prosthetic grafts were patent as shown by color Doppler ultra sound in all followed-up patients.Conclusions This operation is simple and effective for B-CS with hepatic venous (occlusion) but not associated with inferior vena caval pathologic change or long-segment stricture.

Objective To study the relationship between essential hypertension(EH)with serum homocysteine(HCY),uroten-sinⅡ(UⅡ),angiotensin converting enzyme(ACE)and N-terminal pro-brain natriuretic peptide(NT-proBNP).Methods By collec-ting the clinical cases,UⅡwas determined by ELISA and HCY,ACE and NT-proBNP were simultaneously detected by ELISA.The detection results were analyzed and compared between the patients with essential hypertension(EH group)and the healthy con-trols.Results The levels of serum HCY,UⅡ,ACE and NT-proBNP in the EH group were significantly increased compared with the healthy control group;the area under curve (AUC)of serum HCY,UⅡ,ACE and NT-proBNP in the ROC curve in the EH group were 0.93,0.765,0.792 and 0.972 respectively,which showed clinical diagnostic significance.Conclusion The levels of HCY,UⅡ,ACE and NT-proBNP are highly expressed in EH and have significant differences compared with the healthy popula-tion,which has the diagnostic value to EH.

The hydrogen peroxide low temperature plasma sterilization technology solved the problems of thermo-sensitive materials' disinfection and sterilization based on its development and unique characteristics. This paper introduced the researches of clinical application quality control, and showed the hydrogen peroxide low temperature plasma sterilizers were being widely used in hospitals and highly recognized. According to the clinical data and the literatures of the domestic equipment in preliminary application, it could be concluded that the technology maturity of domestic hydrogen peroxide low temperature plasma sterilizers was in a high level. The advantages of using domestic hydrogen peroxide low temperature plasma sterilizers to do disinfection and sterilization included lower cost, safer, faster and non-toxic, etc. Also the management system should be improved and the clinical staff should master the technical essentials, obey the procedures strictly, verify periodically and offer full monitoring to upgrade the quality of sterilization.

AIM: To investigate the effect of antisense oligodeoxynucleotides (AS - ODN) on the intercellsular adhesion molecule- 1 (ICAM- 1 ) expression on endothelial cells in hypoxia/reoxygenation(H/R). METHODS: With cultured glomerular vascular endothelial cell in H/R, the positive percentage of ICAM - 1 expression was measured by flow cytometry before and after giving AS - ODN. RESULTS: The ICAM - 1 expression did not increase on glomerular vascular endothelial cell in 10 hours hypoxia compared to control group, it increased in 6 hours reoxygenation, and decreased by 40.6 % after giving AS- OND. CONCLUSION: AS - ODN may decrease the expression of ICAM- 1 on endothelial cells in H/R.

Objective: To observe the clinical effect of moxibustion on gastralgia of deficiency cold type. Methods: Sixty patients were randomly divided into 2 groups. The 30 patients in the treatment group were treated with Zhao's thunder-fire moxibustion while the other 30 patients in the control group were treated with oral medicine. Results: After one course of treatment, the total effective rate of treatment group was notably higher than that of the control group, showing statistical significance (P<0.05). Conclusion: The total effective rate of thunder-fire moxibustion on gastralgia of deficiency cold type was better than that of the traditional Chinese medicine in relieving epigastralgia.
