OBJECTIVETo investigate necessity of the further processing for adsorptive resin material.

METHODSAccording to GB/ T 16886.4, coagulation tests, haematology tests, in vitro spontaneous platelet-adhesion test and complement activation tests were conducted respectively to assess the in vitro blood compatibility of adsorptive resin material.

RESULTSIn comparison with polypropylene, he adsorptive resin material appears to be a very slight activator to the endogenous blood coagulation system, it can inhibited the exogenous blood coagulation system very significantly (P < 0.01), it can adhere to fibrinogen, red blood cells, reticulocytes very significantly (P < 0.01), and platelet significantly (P < 0.05). The adsorptive resin material is also revealed to be a very significant activator (P < 0.01) to the complement system.

CONCLUSIONSThe in vitro blood compatibility assessment witnesses that it is very necessary for the adsorptive resin material to go through the certain special processing(such as the surface modification and the microencapsulation technology, etc) before its application to human being.

Magnetic mediated particles can be located within tumor volume through special ways are can be heated while exposed to an externally alternating magnetic field,thus kill the tumor cells.Compared with othen hyperthermia a major advantage of magnetic mediated hyperthermia is that of targeting tumor specially and selectively.The evidences of clinical research demonstrate that magnetic mediated hyperthermia will have a promising future and play an important role in tumor therapy.

[Objective] To evaluate the efficacy and safety of quadruple therapy based on moxifloxacin and bismuth in the treatment of Helicobacter pylori eradication failure.[Methods] A prospective,randomized,comparative study was conducted in which 136 eligible patients were randomly divided into the extended quadruple group (66 patients,and the quadruplex therapies are Pectin bismuth 100 mg tid + lansoprazole 30 mg bid + amoxicillin 1000 mg bid + moxifloxacin 400 mg qd) and the classical quadruple group (70 patients,and the quadruple therapies are colloidal pectin bismuth 100 mg tid+ lansoprazole 30 mg bid +tetracycline tablet 750 mg Bid + metronidazole tablets 400 mg bid combination) and were under treatment for 14 days.One month after the treatment,endoscopy,rapid urease test,and 13-carbon/ 14-carbon urease breath test were used to evaluate the adverse effects and adherence of the drugs in the two groups respectively.[Results] In the extended quadruple group,among 60 patients who had completed the final treatment and follow-up survey,55 were successfully treated,with eradication rates of (83.3％,55/66)and 91.7％ (55/60) according to intention-to-treat (ITT) and Per-protocol (PP) respectively.In the classic quadruple group,64 patients completed the final treatment and follow-up survey.Among them,37 cases were successful,and the eradication rates according to ITT and PP remedy are 52.9％ (37/70) and 57.8％ (37/64) respectively.The difference was statistically significant (P ＜ 0.001).Adverse drug reactions and compliance monitoring showed no significant difference between the two groups (P ＞ 0.05).[Conclusion] The quadruple therapy based on moxifloxacin and bismuth displays a higher eradication rate than that of the classical bismuth quadruple therapy on the first-time elimination failure of Helicobacter pylori while shows no difference in safety consideration,thus can serve as remedial therapy for the primary Hp eradication failure.

Rapid and accurate diagnosis of pathogens is the responsibility of the clinical microbiology lab.Effective implementation of this function requires standard procedure of specimen collection and processing.In order to improve the ability of infectious disease diagnosis,clinical microbiology laboratory should strengthen the communication with the clinicians,to improve the quality and quantity of specimens.Meanwhile,microbiology laboratory should learn some clinical knowledge and understand the demand and development of clinical practice.Clinical microbiology lab should emphasize patient-oriented and multidisciplinary close cooperation,for improvement of pathogen diagnosis level.

In this work, rare specific binders to botulinum neurotoxin antigen were selected from human phage immunized library through three rounds of panning in vitro. Of them, clone ScFvB17 is of high affinity and specificity to target antigen. B17 is of 750bp encoding 250 amino acid. Analysis results of gene structure showed V-genes of B17 belonging respectively to VH4 or? chainⅡ family are new antibody Fv genes. More important result showed that recombinant ScFvB17 expressed in E.coli could bind specific for neurotoxin competing with antiserum. Successful selection of human phage antibody library and obtaining specific ScFv against botulinum neurotoxin serotype A provide useful materials for further study on detection of neurotoxin and human engineering therapeutic antitoxin.
