ABSTRACT
Objective To analyze the profile of dermcidin (DCD) changes in different stages of acute coronary syndrome (ACS) by quantifying the serum 4 183Da DCD peptide fragment deriving from different ACS patients treated with early antithrombotic therapy.Methods A total of 118 patients with confirmed diagnosis of ACS were enrolled. Immediately after visiting a doctor, the venous blood was collected and afterwards instantly the patient was given orally 300 mg of aspirin and 300 mg clopidogrel, and according to the patient's condition and the consent of his/her or acknowledgement of family members achieved, emergency percutaneous coronary interference (PCI) or thrombolysis or conservative treatment was adopted separately. After anti-thrombotic treatment, at 2, 4, 6, 8, 10, 12, 16, 20, 24, 32, 40, 48, 60 and 72 hours, venous blood was collected and serum isolated respectively. The concentration of 4 183Da DCD fragment in serum was determined by matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF-MS). Simultaneously, the myoglobin (Myo), cardiac troponin I (cTnI) and MB isoenzyme of creatine kinase (CK-MB) were also detected.Results The mean relative strength of nature logarithmic transformations of 4 183Da DCD fragment of 118 patients with ACS was 2.75±1.02 before treatment on admission, and after intervention therapy (mainly antithrombotic therapy) it was decreased to 1.84±1.19 (P = 0.005) and 1.74±1.12 (P = 0.000) at 2 hours and 4 hours, respectively, and then after 4 hours it was slightly elevated. 4 183Da polypeptide increased earlier than myocardial injury markers.Conclusion Aspirin and clopidogrel can significantly decrease the concentration of 4 183Da DCD peptide fragment in serum in patients with ACS, which indicates that the DCD fragment could be used as one of the indexes for observation on early efficacy of antithrombotic therapy.
ABSTRACT
Objective To investigate the predictive value of 4 183 Da peptide of dermcidin protein in the early diagnosis and differential diagnosis of ischemic heart disease.Methods A prospective controlled study was conducted.Serum samples were drawn from 161 patients with acute coronary syndrome [ACS,including 46 patients with unstable angina (UA),23 with acute non-ST elevation myocardial infarction,and 92 with acute ST segment elevation myocardial infarction],111 subjects for routine physical examination,including 45 patients with hypertension history,42 with coronary heart disease,22 with diabetes,and 54 patients with non-ACS (including pulmonary embolism,aortic dissection aneurysm,arrhythmia,myocarditis,coronary myocardial bridge,pleurisy,pneumothorax,pneumomediastinum,rib fracture,reflux esophagitis,peptic ulcer,and pancreatitis) to serve as controls.4 183 Da peptide of dermcidin protein was assessed with matrix assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS) technology,and myeloperoxidase [MPO,determined by point-of-care testing (POCT) and enzyme linked i mmunosorbent assay (ELISA),respectively],high sensitive C-reactive protein (hs-CRP),heart type fatty acid binding protein (H-FABP),myoglobin (MYO),cardiac troponin Ⅰ (cTnⅠ),and MB isoenzyme of creatine kinase (CK-MB) were quantitated with biochemical analysis.The power of the biomarkers above for early diagnosis and differential diagnosis for ischemic heart disease were judged by comparison of their sensitivity and specificity.Results ① It was showed by one-way ANOVA that 4 183 Da peptide was higher in ACS group than that in control group (relative abundance:22.05 ± 16.97 vs.15.52 ± 14.09,P =0.001),but no difference was found between ACS group and non-ACS group (relative abundance:22.05 ± 16.97 vs.19.99 ± 17.63,P =0.416).② The specificity and sensitivity of the 4 183 Da polypeptide and MPO for predicting ACS and UA were compared with the receiver operating characteristic curve (ROC).It was showed that the 4 183 Da polypeptide had predictive values for ACS and UA,and the areas under the ROC curve (AUC) was 0.625 and 0.651 (both P ＜ 0.01),but MPO was not found to have predictive value (AUC was 0.440 and 0.336,respectively,both P ＞ 0.05).③ It was showed by the values of multi-markers in differential diagnosis of ACS and non-ACS disease that the specificity and sensitivity of 4 183 Da peptide in the differential diagnosis of acute myocardial infarction (AMI) and non-ACS disease were less than those of MYO,cTnⅠ,H-FABP,markers of myocardial damage,which AUCs were 0.569 vs.0.796,0.833,0.838,and equal to MPO (POCT/ELISA) and hs-CRP,AUC of which was 0.569 vs.0.505 (POCT)/0.477 (ELISA) and 0.545.But both the value of 4 183 Da peptide and MYO,cTnⅠ,H-FABP in the differential diagnosis of UA and non-ACS disease was not found,where AUC was 0.456,0.525,0.658,0.568.Conclusion 4 183 Da polypeptide,a fragment of dermcidin protein,may have association with the onset of ischemic heart disease,and may be helpful in the early diagnosis of ACS.

Objective To observe the effect and mechanism of HA1077 on bone mesenchymal stem cells (BMSCs) promoting wound healing. Methods (1) In vitro study: rats' BMSCs were har-vested and divided into three groups randomly, ie, control group, induction group and HA1077 group. In control group, culture medium was DMEM with 10% fetal bovine serum. In induction group, induction medium was DMEM which consisted of 10% FBS, 8μg/ml EGF and epithelium culture condition medi-um. In HA1077 group, culture condition medium was the induction medium pins 10 μmol/L HA1077. At day 7 after replanting, CK19 expression, PCNA expression and cell cycle among three groups were clarified by flow cytometry. (2) In vivo study: rabbit's BMSCs were isolated. Six pieces of full skin loss wound were created on the back of a rabbit, with three pieces of wound on the half side of back. The wound was round and 3 cm in diameter. Eight New Zealand rabbits were randomly divided into four groups, ie, control group (Group A), EGF control group (Group B), BMSCs group (Group C) and BMSCs + HA1077 group (Group D). Wounds were treated by normal saline in Group A and by EGF (50 U/cm2) in Group B. Besides EGF,1 ml of BMSCs suspension (2 × 106/ml) was used for wound re-pair in Group C. 0.5 ml HAIO77(20 μmol/L), BMSCs and EGF were used together for wound repair in GronpD. At days3, 7and 14 after injury, wound elosuroindex (WCI) was calculated. Results In vitro study:the positive rate of CK19 in the HA1077 group was (40.31±0.82)%, higher than (11.13±2.14)% in the induction group(P < 0.01). The PCNA positive rate and the S phase, cell quantity in HA1077 group were also higher than that in the induction group. In vivo study: WCI was (86.20±1.92) % in Group D at day 14 after injury, obviously higher than that in other three groups. Conclusions HA1077 can promote BMSCs' entering into S phase, expressing PCNA and differentiating and expressing CK19. In vivo combination of HA1077 with BMSCs may facilitate wound healing.

ABSTRACT
BACKGROUND: As a typical puny cluster in China, peasant-workers have aroused extensive attention because of their social situation. Therefore, it has important praxis significance for establishing harmonious society to penetrate into their mental health status and improve their mental health level.OBJECTIVE: To investigate the mental health status of home-going peasant-workers, so as to provide a reliable basis for the effective intervention of their mental crisis.DESING: A cross-sectional survey.SETTING: Department of Educational Science of Hengyang Normal University.PARTICIPANTS: The investigation was conducted in 15 provinces of China in February 2005. By means of cross-sectional survey, 300 randomly selected home-going peasant-workers were surveyed during the Spring Festival.METHODS: The peasant-workers were tested individually with symptom checklist-90 (SCL-90); they were given uniform directions and answered each question individually according to their own conditions in the latest week. All the answer papers were handed in on the spot. The data of SCL90 were input with Optical Mark Reader 2000 (OMR2000) into the computer for statistical analysis. The questionnaire in which more than 5 items were left unanswered or the total score was below 95 points was considered to be invalid and therefore rejected for analysis. All the data were input into the computer and statistically analyzed with SPSS 11.0 software; the intergroup differences of the measurement data were compared with the t test or analysis of variance.MAIN OUTCOME MEASURES: ① general mental health status of the home-going peasant-workers; ② mental health status compared among the home-going peasant-workers of different gender, educational level, term on duty and earning.RESULTS: Totally 300 questionnaires were sent out, 275 were handed in,and the collective rate was 91.67%. Finally 245 effective participants entered the analysis of results, including 118 males and 127 females, aged 16-52 years old, with an average of 26.09 years old. The investigated results of SCL-90 showed that ① The total score and number of positive items of SCL-90 in the tested peasant-workers were significantly higher than those of Chinese adult norm (173.13±44.35, 129.96±38.70, t=15.237,P ＜ 0.001; 52.96±20.27, 24.92±18.14, t=21.654, P ＜ 0.001). ②The scores of somatization, obsession-compulsion, interpersonal sensitivity, depression,anxiety, hostility, phobia anxiety, paranoid ideation and psychoticism of the tested peasant-workers were significantly higher than those of the Chinese adult norm (1.73±0.55, 1.37±0.48, t=10.260, P ＜ 0.001; (2.12±0.56, 1.62 ±0.58, t=14.092, P ＜ 0.001; 2.10±0.59, 1.65±0.61, t=12.076, P ＜ 0.001;1.99±0.59, 1.50±0.59, t=13.072, P ＜ 0.001; 1.88±0.53, 1.39±0.43; t=14.260,P ＜ 0.001; (1.98±0.69, 1.46±0.55, t=11.951, P ＜ 0.001; 1.74±0.58,1.23±0.41, t=13.692, P ＜ 0.001; 2.00±0.61, 1.43±0.57, t=14.647, P ＜ 0.001;1.81±0.57, 1.29±0.42, t=14.472, P ＜ 0.001). ③ The mental health status had no obvious differences among the peasant-workers of different gender,educational level, earning and term on duty.CONCLUSION: The mental health status of the home-going peasant workers is significantly lower than that of Chinese norm, gender, educational level, earning and term on duty have great influence on the mental health of the home-going peasant-workers.
ABSTRACT
BACKGROUND: As a typical small cluster of social vulnerable groups in China, peasant-workers have aroused extensive attention because of their social situation. Therefore, it has important praxis significance for establishing harmonious society to penetrate into the status of their satisfaction with life and improve their quality of life.OBJECTIVE: To investigate the status of satisfaction with life of homegoing peasant-workers so as to provide a sound basis for improving their quality of life.DESIGN: A simple random sampling survey.SETTING:Department of Educational Science of Hengyang Normal University.PARTICIPANTS: This investigation was conducted in 15 provinces of China in February 2005. Totally 300 home-going peasant-workers weresurveyed during the Spring Festival.METHODS: The peasant-workers were tested individually with the Satisfaction with Life Scale (SWLS). It was made up of 5 items:The first item was "In most ways my life is close to my ideal ", the second was "The conditions of my life are excellent", the third was "I am satisfied with my life", the fourth was "So far I have gotten the important things I want in life", the fifth was "If I could live my life over, I would change almost nothing". Using the 1-7 scale below: 1-Strongly disagree, 2-Disagree, 3-Slightly disagree, 4-Neither agree nor disagree, 5-Slightly agree, 6-Agree, 7-Strongly agree.The test-retest reliability of this scale was higher than 0.80, the content-related validity was 0.60, and the crieterionrelated validity was higher than 0.50. They were given uniform directions and answered each question individually according to their own conditions in the latest week. All the answer papers were handed in on the spot. The data of SWLS were input into the computer for statistical analysis. The questionnaire in which more than 4 items were selected the answer of "neither agree nor disagree" were considered to be invalid and therefore rejected for analysis. All the valid data were input into the computer and statistically analysed with SPSS 11.0 software; differences among groups were compared with t test or analysis of variance.MAIN OUTCOME MESURES: The scores of SWLS answered by the peasant-workers.RESULTS: Totally 300 questionnaires were distriluted and 275 of them were collected, with a recovery rate of 91.67%, of which 245 were valid for result analysis, including 118 males and 127 females aged from 16 to 52 years old with the mean age of 26.09 years. They came from 15 provinces of China and from 16 kinds of vocation. Their monthly-earning was from 200 yuan to 8 000yuan. The investigated results of SWLS showed that: ①29.8% of the tested home-going peasant-workers were inclined to be satisfied with their life, and 41.6% of them were inclined to be unsatisfied. ②There was obviously sexual difference in the item of "I am satisfied with my life"among the tested homegoing peasant-workers.[(4.50±1.70,3.95±1.53) (t=2.65,P ＜ 0.001 )]. ③Earning markedly affected their feeling of "The conditions of my life are excellent" and "So far I have gotten the important things I want in life" [(3.79±1.85, 3.98±1.64,4.07±1.44,4.84±1.14) (F=3.068,P ＜ 0.05); (4.64±2.03,3.72±1.68,4.07±1.67,4.19±1.28) (F=2.813,P ＜ 0.05)]. ④there was no significant difference of satisfaction with life of the tested home-going peasant-workers in educational level and term on duty. CONCLUSION: Majority of the home-going peasant-workers were unsatisfied with their living. Sex and earning were the important factors that affected their satisfaction with life, educational level and term on duty had weakly correlated with it.
