ABSTRACT
Objective To investigate the clinical significance of cortactin antibody in myasthenia gravis (MG).Methods Cortactin antibody in the serum of 100 MG patients, 40 normal controls and 40 other neuroimmune diseases patients was examined by Western blotting and ELISA using purified recombinant human protein cortactin as antigen .Acetylcholine receptor antibody ( AchR-ab ) and muscle specific kinase antibody (MuSK-ab) were parallely measured by ELISA.Results Antibodies to cortactin were found in nine (9％) serum samples of 100 MG patients.Four of the nine cortactin antibody positive sera were also positive for AChR-ab.The rest five MG patients only had antibodies against cortactin ( no detectable AChR-ab or MuSK-ab).None of the control subjects (including 40 normal controls and 40 other neuroimmune diseases patients ) had cortactin antibodies.Most (7/9) of the cortactin antibody positive MG patients presented with early-onset subgroup.Patients only with cortactin antibodies did not appear to have thymoma.Patients with MG who had both AChR and cortactin antibodies showed maximum involvement of muscles and severe Osserman's classification ( three cases of type ⅡB and one case of type Ⅳ) . Conclusion Cortactin antibody may be a new antibody for MG , which can provide clues for further exploring the potential pathogenic mechanisms of the disease .
ABSTRACT
Objective To investigate the impacts of water supply on water quality in the pipeline of the dental comprehensive treatment platform to contribute to pollution control.Methods Totally 8 platforms from the stomatological department underwent 2-a detection and tracing.The water sources included tap water,distilled water and filtered water,and the discharge water went through sampling and bacteriological analysis before and after disinfection.Results The mean numbers of colonies by tap water,distilled water and filtered water were (472±385),(380±372) and (446±382) cfu/ml respectively,and the qualification rates by tap water,distilled water and filtered water were 33.3％,45.8％ and 37.5％ respectively.All the colonies numbers were limited within 0 and 60 cfu/ml with the qualification rate being 100％ after disinfection.Conclusion Water source cannot relieve bacterial infection effectively,and disinfection eliminates bacteria and improves water quality in the pipeline of the dental comprehensive treatment platform.
ABSTRACT
Objective To investigate and analyze the clinical efficacy of psychological intervention in the treatment of uterine atony postpartum hemorrhage and its influence on the quality of life. Methods 100 cases of uterine atony postpartum hemorrhage were selected in our hospital from March 2015 to September 2016.The subjects were randomly divided into the control group and the experimental group, 50 cases in each group. The patients in the control group were treated with oxytocin, and the experimental group was treated with Xinmu Pei combined with psychological intervention.The treatment effect and quality of life total score were compared between two groups. Results After the corresponding treatment, the effective rate of the experimental group was 92.0％, which was significantly higher than that of the control group(72.0％), the difference was statistically significant (P<0.05). The total score of quality of life in the experimental group was (75.2±11.2) points, significantly higher than that of the control group (64.2±9.3), the difference was statistically significant (P<0.05). Conclusion The clinical effect of psychological intervention of hemabate in treatment of postpartum hemorrhage maternal, can improve the therapeutic effect to a great extent, improve the quality of life of patients, with further clinical promotion and application significance.
ABSTRACT
Objective To investigate the distribution and drug resistance of pathogens isolated from blood culture samples from January 2012 to October 2013 to provide the basis for clinical lection of antibacterial drugs.Methods The blood samples were col-lected from the patients with suspected blood infection and cultured by the BD BACTEC 9120 automatic blood culture instrument. The samples with positive results were performed the bacterial identification and the drug sensitivity test by using the VITEK-2 COMPACT automatic bacterial identification instrument.Results A total of 969 strains of pathogens were isolated from blood cul-ture samples,including 540 strains(55.7%)of Gram-positive bacteria,413 strains(42.6%)of Gram-negative bacteria and 16 strains (1.7%)of fungi.The top 3 isolated pathogenic bacteria were Staphylococcus epidermidis,Escherichia coli and Staphylococcus au-reus.Staphylococcus epidermidis and Staphylococcus aureus were highly resistant to penicillin,sensitive to vancomycin and linezol-id;Escherichia coli and Klebsiella pneumoniae were highly sensitive to imipenem and Piperacillin/tazobactam.Conclusion It is nec-essary to understand the blood culture results timely so as to provide the basis for clinical antibacterial therapy and the improvement of the cure rate.
ABSTRACT
Objective: To study the reliability and validity of Adolescence Ego Identity Crisis Scale (AEICS) Method: 467 middle school, high school and college students received the test of AEICS Results: The test-retest reliablity coefficients were in 0 655～0 912 The split-half reliability coefficient was 0 604 The Crobach were in 0 416～0 793,construct validity and criteria validity were acceptable Conclusion: AEICS has psychometrically acceptable reliability and validity
