Objective To explore the differences of serum expression of cystatin C,macrophage migration inhibitory factor (MIF)and matrix metalloproteinase-1 (MMP-1)in elderly patients with coronary artery disease.Methods 120 cases of senile cor-onary heart disease patients in the department of cardiovascular medicine from July 2010 to August 2012 were selected and divided into the control group (n=30),stable angina pectoris group(SAP group,n= 34),unstable angina group (UA group,n=28)and a-cute myocardial infarction group (AMI group,n=28)according to the results of coronary arteriography combined with the electro-cardiogram and myocardial enzyme spectrum test.The serum levels of cystatin C,MIF,MMP-1 and C reactive protein (hs-CRP) were compared among the four groups,and correlations of the four indicators were analysed as well.Results There were significant differences in the serum levels of cystatin C,MIF,MMP-1 and hs-CRP among the four groups(P <0.05).The serum levels of cys-tatin C,MIF and MMP-1 were gradually increased with the progression of disease,and significant differences were found between any two groups(P <0.05).There were significant differences in the levels of hs-CRP between the AIM group and the other three groups(P <0.05).While among the control group,SPA group and UA group,no significant differences were found in the levels of hs-CRP between any two groups(P >0.05).The significant positive correlations were observed among cystatin C,MIF and MMP-1.Conclusion The serum levels of cystatin C,MIF and MMP-1 have a gradually increasing trend with disease progression in pa-tients with coronary heart disease,which could be important indicators of disease evaluation.

BACKGROUND: Two-dimensional electrophoresis (2-DE) is precise and effective for the isolation and analysis of complex protein mixtures, has become one of valuable key techniques for proteome. Mice models were as research subjects to model human disease status, one of important methods for cardiovascular disease. The establishment and optimization of 2-DE for proteomes of mice myocardium will provide basis for heart disease.OBJECTIVE: To establish and optimize a stable technique of 2-DE for proteomic analysis of mice myocardium.DESIGN: Mice were used as research subjects, observational comparative study.SETTING: Department of Pathology, Nanfang Hospital Affiliated to Southern Medical University.PARTICIPANTS: The experiment was performed at the Department of Pathology, Nanfang Hospital Affiliated to Southern Medical University between February and September 2004. Totally 12 male BABL/c mice of 4-5 weeks without special-pathogen free with the body mass of 12-15 g were selected, which was provided by the Experimental Animal Center of Southern Medical University.METHODS: The mice were put to death by dislocation of cervical vertebra under drugged state to obtain heart. Various protein extraction method,loading sampling buffer, strip range of IPG, sampling volume of protein,staining method and so on were compared, analyzed, scanned and digilized,and then performing image analysis. Each link in the study was established and optimized.MAIN OUTCOME MEASURES: Resolution of protein and reproducibility of the trial.RESULTS: A method that was optimal for cardiac tissue can isolate about a total of 910 protein spots on pH 4-7 gel strips. 200 μg was fit for silver stain while 1000 μg was for Coomassie stains. It was found that in the myocardium of normal mice about (920±30) protein spots were obtained in 17 em pH 3-10 L gel strip, while around (880±30) were gained in the pH 4-7 L gel strip. The mean matching rate achieves to 86. 9%.CONCLUSION: The findings of the trial showed that 2-DE technique can be effectively applied for proteomics of myocardium of mice to regulate and optimize, and relatively stable separation method of myocardial protein was established.

Objective To investigate the changes and significance of serum inflammatory factors in coronary heart disease (CHD) patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) ,and the treatment effects of continuous positive airway pressure (CPAP).Methods A total of 76 CHD patients in Renmin Hospital of Wuhan University from October 2007 to October 2008 were enrolled.Polysomnography (PSG) was performed in these CHD patients to identify if they were complicated by OSAHS.The levels of inflammatory factors including TNF-α, IL-6, high sensitive C-reactive protein (hs-CRP) in serum were determined in the CHD patients and 23 normal subjects.The CHD patients with mederate-severe OSAHS (AHI≥ 15 episodes/hour) were treated by Auto-CPAP for 3 months and all parameters above were measured again.Results There were 41/76 (53.9%) of CHD patients had mederate-severe OSAHS and were treated with CPAP.The levels of TNF-ct,IL-6 and hs-CRP were significantly higher in the CHD patients than those in the normal controls (all P <0.01) ,and were significantly higher in moderate-severe OSAHS patients than those in the non-OSAHS CHD patients.Auto-CPAP ventilation significantly decreased the levels of inflammatory factors in the CHD patients with moderate-severe OSAHS.Conclusions An obvious proinflammatory state is detected in CHD patients ,and is aggravated with OSAHS.CPAP is a useful treatment for CHD patients with mediate to severe OSAHS.

Objective: To describe the status and trend of dietary energy, protein and fat pattern of Chinese residents. Method : 23 470 households including 68 962 subjects were randomly sampled from 132 counties in 31 provinces, autonomous regions and the municipalities. The 24 h dietary recall method for 3 consecutive days was used in dietary survey and weighing method was used for condiment intake. Results: The average energy intake per reference man per day was 9.42 MJ (2 250.5 kcal), 11.8% and 29.6% from protein and fat respectively. The percentages of energy from fat of big city residents arrived 38.4%. The percentages of energy from cereals, animal food and pure energy food were 57.9%, 12.6% and 17.3% respectively. The average protein intake per reference man per day was 65.9 g, 52%, 7.5% ,25.1% and 15.3% from cereals, bean and bean product, animal food and other foods respectively. The average fat intake per reference man per day was 76.3 g, 39.2% from animal food. Conclusion: The dietary change of Chinese residents represents the characteristics of the transition period, including the decrease of energy and protein intake per capita, decrease of the percentage of dietary energy supplied by cereals and increase of fat intake per capita,especially from animal foods, and the proportion of energy contributed by fat.

BACKGROUND: Pergolide and madopar are the effective medicines to treat Parkinson disease, but the effects on the prognosis of patients with Parkinson disease are still under discussion. The progress of neuroimaging makes it possible to evaluate quantitatively the effect of the drug treatment on the prognosis of Parkinson disease.OBJBCTIVE: To observe the influence of pergolide or madopar as initial treatment on the prognosis and the striatal dopaminergic neuron in patients with early Parkinson disease by means of 99Tcm-TRODAT-1 dopamine transporter imaging single-photon emission computed tomtheography (SPECT) in combination with Parkinson disease scale.DESIGN: A randomized grouping, parallel control and placebo control trial.SETTING: Department of Neurology, the 81 Hospital of Chinese PLA;Department of Neurology and Department of Nuclear Medicine, Changhai Hospital of the Second Military Medical University of Chinese PLA.PARTICIPANTS: Thirty-six patients with early Parkinson disease who were recruited at the Specific Clinic of Parkinson Disease in the Shanghai Changhai Hospital affiliated to the Second Military Medical University of Chinese PLA and did not receive any drug treatment before, were enrolled between February and July 2002. They were randomly divided into artane control group (n=12), pergolide-treated group (n=12) and madopar-treated group. The diagnosis accorded with the clinical diagnostic standard set by United Kingdom Society of Parkinson Disease. This protocol was approved by the Medical Ethics Committee of Changhai Hospital, and all the subjects were enrolled in this study with informed consent.INTERVENTIONS: After test with unified Parkinson disease rating scale (UPDRS) and 99Tcm-TRODAT-1 SPECT, patients in the artane control group, pergolide-treated group and madopar-treated group were treated with corresponding drugs respectively, and each capsule of artane, pergolide and madopar contained drug of 0.05, 0.05 and 125 mg respectively. In the 1st week, the dosage was 1 capsule for each time, once a day, and then the daily dosage was increased by 1 capsule per week later, and the daily dosage reached 0.2, 0.2 and 500 mg respectively after 1 month, and then the dosages were kept constant. The curative effects were evaluated with UPDRS at 6 and 10 months after treatment. At 10 months after treatment,the 99Tcm-TRODAT-1 specific intakes of ipsilateral or contralateral striatum of the affected limb were tested with striatum dopamine transporter SPECT and semi-quantitative analysis.MAIN OUTCOME MEASURES: ① Changes of percentage of 99Tcm-TRODAT-1 decrease of ipsilateral or contralateral striatum of the affected limb at 10 months after treatment were compared among the three groups;② Changes of UPDRS scores before and after treatment were compared among the three groups.RESULTS: Totally 36 patients were involved in the study, and 1 case lost in each of the 3 groups respectively at 10 months after treatment, finally 33 cases entered the analysis of results. ① Changes of percentage of 99Tcm-TRODAT-1 decrease of ipsilateral or contralateral striatum of the affected limb at 10 months after treatment: At 10 months after treatment, the percentage of 99Tcm-TRODAT-1 decrease of ipsilateral or contralateral striatum of the affected limb were obviously higher in the madopar-treated group than in the artane control group and pergolide-treated group [(46.3±19.4)%, (28.9±13.0)%, (34.4±18,1)%; (47.5±20.8)%, (31.8±15.6)%, (33.8±17.2)%; P all ＜ 0.05]. ② Changes of UPDRS scores before and after treatment: As compared with the UPDRS scores before treatment, there was no obvious change in the artane control group at 10 months after treatment,but those in the madopar-treated group and pergolide-treated group were obviously decreased [(15.5±8.68), (6.4±9.05); (15.8±6.75), (10.36±8.30); Pall ＜ 0.05].CONCLUSION: Both madopar and pergolide can ameliorate the symptoms of early Parkinson disease, but they had different influences on the prognosis of patients with Parkinson disease. Madopar may accelerate the apoptosis of dopaminergic neuron and then aggravate the severity, but pergolide does not affect the prognosis of Parkinson disease, so it is a more suitable selective drug for the treatment of early Parkinson disease.
