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.

Objective To observe the repairing effect of hyaluronic acid hydrogel on rat articular cartilage defects .Methods One hundred and twenty SD rats were randomly divided into group A (natural repair group) ,group B (hyaluronic acid group) and group C (composite material group) ,36 rats was in each group and 12 rats were used to obtain cartilage cells .Full‐thickness articular os‐teochondral defects(2 .5 mm in diameter and 3 .0 mm in depth)were created mechanically in femoral trochlea of rats .Histological and biochemical method were used to evaluate the repairing effect of different material at different points(10 ,20 ,40 d) .Results Repairing effect of group C was best by histological and biochemical method at different points ,followed by group B ,and they were better than that of group A .Conclusion Hyaluronic acid hydrogel could provide cartilage cell proliferation for porous space truss structure ,and could carry cartilage cells at the same time .the cellular space truss structure have high surrounding tissue compatibil‐ity and biodegradation ,it is helpful for cartilage cell survival ,reproduction and division .

[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.

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 observe the clinical efficacy of Xing Nao An Shen Jie Yu needling method (brain-awakening mind-calming and anti-depression needling method) in treating depression after cerebral stroke. Method Totally 120 patients with depression after cerebral stroke were randomized into two groups: the acupuncture group was intervened by An Shen Xing Nao Jie Yu needling method, while the Western medication group was by oral administration of Fluoxetine Hydrochloride capsules. The Hamilton Depression Scale (HAMD), National Institute of Health Stroke Scale (NIHSS), and Barthel Index (BI) were adopted to evaluate the depression degree, neural function deficit, and activities of daily living after 4-week and 8-week treatments. Result The total effective rate was 96.5% in the acupuncture group, versus 83.9% in the Western medication group, and the difference was statistically significant (P<0.05); the acupuncture group was superior to the Western medication group in improving the HAMD, NIHSS, and BI scores (P<0.01), and its therapeutic efficacy present with a feature of time-effect. Conclusion Xing Nao An Shen Jie Yu needling can significantly improve the symptoms of depression after cerebral stroke, promoting the recovery of neural function and enhancing the quality of life.

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.

In this paper, some study methods of pharmacokinetic, the explanation ways of data and experimental methods of transdermal therapeutic system(TTS) were described. The advancement of modern science accelerates the development of pharmacokinetic of TTS and makes more progress in this field.

Objective:To discuss the diagnosis,treatment of uterus cornea pregnancy.Methods:Retrospective analysis was made in 21 cases of uterus cornua pregnancy is recent 10 years.Results:8 cases were diagnosed uterus cornua,9 cases were misdiagnosed ectopic pregnancy,1 case was misdiagnosed rupture of uterus of artifical obortion,1 case was misdiagnosed pregnancy with uterus septus,1 case was misdiagnosed choriocarcinoma.Surgical treatment was done in 19 patients,and the other 2 cases received conservative therapy.Conclusion:Cornual pregnancy is often misdiagnosed as ectopic pregnancy or other diseases.More careful gynecological and transobdominal ultrasound examination will improve the accuracy of diagnosis.

Objective To study the clinical value of procalcitonin on early diagnosis of sepsis .Methods 60 patients who entered ICU were enrolled in the present study were chosen .The change of procalcitonin , CRP, WBC,ESR,GRANR and the highest temperature was observed dynamically with 1 day and 4 days in hospitalization . The patients were ultimately divided into the two groups according to the diagnostic standard of sepsis ,the sepsis group (SIRS group) and infective systemic inflammatory response syndrome group (NONSIRS group).Results After ana-lyzing the processed data,researchers found that PCT of the sepsis group (6.73 ±1.31)ng/mL was higher evidently than that of the SIRS group(0.25 ±0.05)ng/mL(t=3.10,P<0.05),the area under ROC curve of PCT (0.869) is evidently greater than CRP(0.798),WBC(0.737) and ESR(0.394)(P<0.05),which had statistical significance. Conclusion Procalcitonin is a good index of early diagnosis on sepsis ,therefor,its sensitivity and specificity is higher than the other inflammatory indicators .Finally,procalcitonin can be widely used in clinical trial .
