The charge transfer reaction between albendazole and chloranilic acid in alcohol-acetone solution was studied spectrophotometrically. The apparent molar absorptivity is 8.03×103 L*mol－1*cm－1 at 525 nm. The Beer′s law was obeyed in the range of 0～280 mg/L of albendazode. The composition of complex is 1∶1. The proposed method was applied to the determination of albendazole tablets with satisfactory results.

Interdigitating dendritic cell sarcoma (IDCS)is a rare malignant tumor of the dendritic cell, derived from the hematopoietic tissue.The major clinical manifestation of IDCS is superficial lymphadenopathy, and the enlarged lymph nodes may appear in some atypical ereas,such as the lung,kidney,bladder and the pleura,etc.With the development of the pathological diagnosis and the application of immunohistochemical staining and electron microscopes,the case detection rate is apparently improved.With the high degree of malignant,rapid progress and poor prognosis of the disease,currently,surgical therapy is still the main approach to the treatment of IDCS.

BACKGROUND:Carboxymethyl chitosan (CMCS),a chitin derivative,has a good application performance that makes it become a safe and effective hemostatic material.OBJECTIVE:To determine the hemostatic effect of CMCS and its biosecurity properties.METHODS:(1) CMCS powder was scattered on the caudal vein and liver wounds of Sprague-Dawley rats,and the hemostatic time was recorded as experimental group,while the time for natural haemostasis of the wound was recorded as control group.(2) CMCS powder was scattered on the tail,femoral artery and liver wounds of ICR mice,and the hemostatic time was recorded as experimental group,while the time for natural haemostasis of the wound was recorded as control group.(3) CMCS,Sodium dodecyl sulfate solution and distilled water were respectively applied on the skin of albino rabbits in a skin irritation test.(4) A delayed-type hypersensitivity test of CMCS was carried out by intradermal injection of CMCS in guinea pigs.(5) An intradermal irritation test was carried out by subcutaneous injection of normal saline containing CMCS and normal saline,respectively.Another intradermal irritation test was carried out by subcutaneous injection of the supernatant of CMCS olive oil extract and olive oil,respectively.RESULTS AND CONCLUSION:(1) Compared with the control group,the hemostatic time for caudal vein and liver wounds were significantly shortened in the Sprague-Dawley rats in the experimental group (P ＜ 0.01).(2) Compared with the control group,the time of hemostasis on the tail,femoral artery and liver wounds was significantly shortened in the ICR mice in the experimental group (P ＜ 0.05 or P ＜ 0.01).(3) The CMCS had no irritation to the skin of albino rabbits and no allergic reaction to the skin of guinea pigs.To conclude,the CMCS has good hemostatic effect on the wound in Sprague-Dawley rats and ICR mice,and has no skin irritation,allergic reactions and intradermal irritation reactions in albino rabbits and guinea pigs,which is a relatively safe hemostatic material.

Objective In order to know the effect of heating infusion for premature infants to pro-mote their restoration of physiological function. Methods Divided 160 premature infants who need infu-sion into the experimental group and the control group randomly, there were 80 cases in each group. Normal temperature infusion was used in the control group, while heating infusion was used in the experimental group, compared the body temperature, pluse, respiration, blood pressure, oxygen saturation and the blood ghcose between the two groups. Results There were significant difference about the indexes which had mentioned above between the two groups. Conclusions Heating infusion can effective promote the reha-bilitation of physiological function of premature infants.

Objective:To study the dental and skeletal changes after orthodontic treatment for malocclusion patients with rapid maxil-lary and mandibular expansion companied with fixed appliance.Methods:36 patients underwent the treatment with rapid maxillary and mandibular expansion companied with straight wire appliance.Pre-and post-treatment dental casts and lateral cephalometric radiographs were measured and compared.Results:After treatment,the maxillary and mandibular arch width perimeters increased(P <0.05).The anterior arch depths decreased(P <0.05).No significant differences were found in vertical skeletal variables(P >0.05).U1-SN and U1-NA decreased,L1-MP and L1-NB increased(P <0.05).Conclusion:Dental crowding can be solved effectively and occlusion re-lationship can be kept well with rapid maxillary and mandibular expansion companied with straight wire appliance without influence on the vertical skeletal relationship.

Objective:To investigate efficacy of modified expander in the treatment of non-extraction patients with Angel Ⅰ maloccul-sion.Methods:1 4 Angel Ⅰcases aged 1 0 -1 4 years treated by non-extraction and fixed rapid expander.Jaw bones of the cases were laser scanned before(T1 )and after treatment(T2).The differences of arch width and length between T1 and T2 were analyzed.The In-dex of treatment complexity,outcome and need(ICON)was used to assess the pre-treatment and post-treatment study models.Data were statistically analysed with SPSS1 3.0 software.Results:The arch width increased significantly from T1 to T2.Good occlusal rela-tionship and soft tissue profiles were achieved in all cases.All cases were evaluated as greatly improved by ICON.Conclusion:AngelⅠ malocclusion can be treated successfully by increasing arch width with fixed rapid expander technique without tooth extraction.

Objective To establish a double-antibody sandwich enzyme linked immunosorbent assay (DAS-ELISA) for the rapid detection of germ tube-specific antigens of Candida albicans,and to evaluate its specificity and sensitivity.Methods A DAS-ELISA was established with the monoclonal antibody McAb03.2C1-C2 as the primary antibody,and horseradish peroxidase (HRP) labeled McAb03.2C1-C2 as the secondary antibody.The established assay was used to detect germ tube-specific antigens of Candida albicans in sera from 5 patients with systemic Candida albicans infection and from 6 rabbit models at 12,24,48,72hours,on week 1,2 after infection with Candida albicans.Results A good liner relationship was observed between the absorbance value at 495 nm and antigen concentrations when the titer of McAb03.2C1-C2 was 1 ∶ 4000 and the concentration of coated antigen varied from 1.25 to 40 μg/ml.The specificity and sensitivity of the DAS-ELISA were 95％ and 92％ respectively in the detection of germ tube-specific antigens in the rabbit models.The results of detection with DAS-ELISA in serum specimens from the patients were consistent with those with the routine method.Conclusions A DAS-ELISA is primarily established for the rapid detection of germ tube-specific antigens of Candida albicans,and has shown a satisfactory sensitivity and specificity in the animal model experiment.

Objective To study the concentration of anti-cyclic citrullinated peptide antibody (CCP),rheumatoid factor (RF),immunoglobulin (Ig) in synovial fluid and serum of patients with rheumatoid arthritis (RA),and the positive rate of anti-keratin antibodies (AKA) and anti-perinuclear factor (APF) were also measured.The aim was to explore the diagnostic value of these antibodies in synovial fluid for RA.Methods Thirty RA patients were collected,synovial fluid were withdrawn from the inflamed joints and peripheral blood were collected at the same time.Anti-CCP antibody,AKA,APF and RF were measured.The cut-off value of CCP in synovial fluid was determined through operating characteristic curve (ROC curves) analysis.The antibody levels in serum and synovial fluid were compared.Statistical analyses were performed using t test,and Pearson's correlation test.Results The cutoff value of CCP in RA synovial was higher,which was 29.00 U/ml,with the sensitivity of 87.00％ and specificity of 94.10％.There were significant differences in the concentration among anti-CCP antibody [(326±313) U/ml,(496±454) U/ml,t=-2.399,P＜0.05],IgG [(57±39) mg/L,(173±86) mg/L,t=-7.4792,P＜0.05),RF [(53±36) U/ml,(149±104) U/ml,t=-2.402,P＜0.05] in synovial and blood serum respectively in RA patients.Conchsion The diagnosis of RA is enhanced if anti-CCP antibodies,RF and IgG in synovial fluid are examined.They are supplementary to RA diagnosis and are helpful for clinical practice,especially for patient with very recent-onset RA.
