1.Study on the postmortem stability of heart fatty-acid-binding protein for the diagnosis of early myocardial infraction
Journal of Chongqing Medical University 2007;0(12):-
Objective:To investigate the stability of heart fatty-acid-binding protein(H-FABP)for the postmortem diagnosis of early myocardial infraction.Methods:Rabbit model of myocardial ischemia was induced by ligating the anterior branch of the left coronary artery.The areas of H-FABP depletion in the ischemic myocardial cells were studied by immunohistochemistry,image analysis technique and statistical system.Results:The specimens of normal myocardium kept at 4℃ for 1 to 2 days showed homogenous brown reactions for H-FABP.The depletion of H-FABP became evident when these specimens were kept at 4℃ for 3 days after death,and the depletion area increased with the lapse of postmortem interval.The depletion area of H-FABP in ischemic myocardial tissue also increased with the lapse of postmortem interval.The results of image analysis indicated that the depletion area of H-FABP in ischemic myocardial tissue within 4 d were significantly different from that in the normal control group(P0.05).Conclusion:The H-FABP shows medium postmortem stability,and small influenced by autolysis,which is suitable for detection in corpses at 4℃ 4 days after death.H-FABP as a marker for postmortem diagnosis of AMI has some practical value in forensic medicine.

Cancer Research and Clinic 2016;28(7):455-458,463
Objective To investigate expression of cytokeratin 19 fragment antigen 21-1 (CYFRA21-1) and squamous cell carcinoma antigen (SCC-Ag) in cervical cancer patients with lung metastasis before treatment and their prognostic value. Methods The pretreatment serum expression levels of SCC-Ag and CYFRA21-1 of 72 cervical cancer patients with lung metastasis were measured. Survival rate analysis and Cox proportional hazard model were performed to evaluate the prognostic significance of two pretreatment variables. Results The media survival time (MST) of 72 patients was 14 months, and 38 (52.8 %) patients with pulmonary metastasis occurred in 1 year of treatment. The pretreatment serum SCC-Ag and CYFRA21-1 levels in the patients with tumor diameter over 4 cm or with squamous cell carcinoma were higher than those in the other patients (all P<0.05). The MST in the pretreatment serum CYFRA21-1 positive group (>3.3 mg/L) was higher than that in the negative group (13 months vs 19 months, P< 0.05), and the MST in the SCC-Ag positive group (>1.5 mg/L) was also higher than that in the negative group (14 months vs 21 months, P<0.05). The result of Cox regression analysis showed that the tumor diameter (OR = 11.6, P = 0.01), pretreatment serum SCC-Ag (OR= 4.2, P= 0.01) and CYFRA21-1 (OR= 8.2, P= 0.05) levels were independent prognostic factors of overall survival. Conclusion Pretreatment CYFRA 21-1 and SCC-Ag levels may be considered as useful prognostic indicators for cervical cancer patients with lung metastasis.

5.Application of the detection of heart fatty acid-binding protein to early diagnostic of myocardial injury
Chinese Journal of Medical Education Research 2006;0(08):-
Heart fatty-acid-binding protein(H-FABP) is small molecular weight cytosolic protein that is abundant in the heart and has tissue specificity. Concentration of H-FABP changes regulation in serum after the myocardial damage. In addition it has a positive correlation with the degree of myocardial damage. It is an early diagnostic biochemical marker of acute myocardial ischemia. The advance of H-FABP in the research on physiochemical nature,and its application for myocardial injury and prospective study of sudden cardiac death in forensic science were reviews.

Objective To investigate the correlations of Eotaxin-1,rheumatoid factor (RF) and anti-cyclic citrullinated peptide (CCP) antibody with the activity of rheumatoid arthritis (RA).Methods A total of 58 patients with early RA,46 patients without RA and 53 healthy controls from our hospital during December 2014 and December 2015 were enrolled in our study.The activity of RA was evaluated by the swollen joint count (SJC),tender joint count (TJC) and DAS28 score.The levels of serum Eotaxin-1 and antiCCP antibody were detected by ELISA and serum RF levels were determined by the immunological turbidimetry.The comparisons of serum Eotaxin-1,anti-CCP antibody and RF levels between different groups were performed with ANOVA and their correlations with SJC,TJC and DAS28 score were analyzed by Spearman rank correlation.Results The levels of Eotaxin-1,anti-CCP antibody and RF in RA patients were (96.02 ± 2 1.07) pg/mL,(183.42 ± 87.45) U/mL and (119.09 ± 62.30) RU/mL,respectively,which were significantly higher than those in the patients without RA and healthy controls (P < 0.01).The levels of serum Eotaxin-1 in RA patients were significantly related to TJC,SJC and DAS28 score (P < 0.01),while the levels of anti-CCP antibody were related to TJC and DAS28 score.The levels of RF were only related to DAS28 score.Conclusion The levels of serum Eotaxin-1 and anti-CCP antibody in RA patients are significantly correlated with the activity of RA,which may be new serum markers to monitor the activity of RA.

OBJECTIVE:
To study the clinical characteristics of early tinnitus in patients with sudden deafness.
METHOD:
Forty-seven patients with sudden deafness and early tinnitus recieved subjective review and filled out classified questionnaire of tinnitus. By pure tone audiometry and tinnitus matching test, we obtain the distribution, quantity and matching loudness of tinnitus patients.
RESULT:
(1) Objective examination: the most common frequencies of tinnitus were 8000 Hz and 4000 Hz. The most common numbers were two frequencies. The matching loudness was (16.63 ± 8.37) dB. (2) Subjective examination: the tinnitus was monotone (74.0%), sustained (89.0%), third level loudness (45.0%), third level annoying (60.0%), high frequency (83.0%), sound of cicadas (66.7%). The most influencing factors were hearing (28.2%) and mood (29.5%). (3) Relationship between tinnitus and pure tone hearing threshold curve: there was a significant correlation between the frequency of pure tone audiometry and the matching loudness of tinnitus (r = -0. 370, P < 0.01). There was no significant correlation between the frequency of pure tone tinnitus and the matching loudness of tinnitus (r = -0.083, P > 0.05).
CONCLUSION
(1) The results of subjective examination were consistent with those of objective examination. (2) The tinnitus should be considered in the early treatment of sudden deafness.
