Objective To explore the change of monocyte chemotactic factor-1 protein(MCP-1)and matrix metalloproteinase-9( MMP-9)of patients with coronary artery disease( CAD)following percutaneous coronary interventional( PCI). Methods Fifty patients underwent PCI procedures for CAD compromising a single coronary artery were selected as PCI group and 30 healthy individuals with normal findings by coronary angiography were selected as the control group. Plasma MCP-1 and MMP-9 were measured in all the subjects. Results The plasma MCP-1 level of patients with CAD after PCI was(19. 87 ± 5. 31)ng/ L,higher than that before operation((15. 71 ± 5. 23)ng/ L,t = 3. 95,P < 0. 01). Whereas in the control group,the MCP-1 level after coronary angiography was(13. 78 ± 5. 58)ng/ L,which was as same as that before operation (12. 42 ± 5. 39 ng/ L,P = 0. 34). Plasma MMP-9 level in the CAD patients after PCI procedures was(22. 69 ± 5. 97)mg/ L,higher than that before operation((19. 52 ± 5. 72)mg/ L,t = 2. 71,P < 0. 01). There was no significant difference in term of plasma MMP-9 level in control group befor and after operation((17. 53 ± 5. 51) mg/ L vs.(16. 69 ± 5. 42)mg/ L,P = 0. 55). Conclusion Plasma MCP-1 and MMP-9 increase in CAD patients following PCI procedures. But their roles in the vascular restenosis following the procedures need further investigation.

Activity of IL-1 produced by peripheral blood monocytes stimulated with lipopolysaccharide in vitro was detected from 17 acute cases, 14 chronic cases and 19 advanced cases of schistosomiasis japonica. It was found that the level of IL-1 was significantly increased and positively related to the body tempereture in the group with acute schistosomiasis. The activity of IL-1 was statistically reduced in the chronic and advanced groups, especially in the latter. After inhibiting the synthesis of prostaglandin with indomethacin, the level of IL-1 was significantly increased in three groups of patients, but no apparent change in the normal contro group. The results indicate that IL-1 may play an important role in inducing the inflammatory reaction in patients with acute schistosomiasis japonica and in the immunoregulation in the chronic stage. The changes of IL-1 activity in patients with schistosomiasis japonica may be closely related to prostaglandin.

OBJECTIVETo analyze the clinical features and gene mutations in an adolescent patient affected with late-onset multiple aeyl-CoA dehydrogenase deficiency (MADD) with severe fatty liver.

METHODSPotential mutations of the ETFDH gene were detected with polymerase chain reaction (PCR) and DNA sequencing.

RESULTSThe 13-year-and-10-month girl has presented with weakness without any other special manifestation. Laboratory tests demonstrated an elevation of myocardial enzyme levels, total cholesterol, lactic acid and abnormal serum free fatty acids. H magnetic resonance spectroscopy revealed severe fatty liver. An increase in multiple plasma acyl-carnitines was detected by gas chromatography/mass spectrometry and isobutyrylglycine in urine by screening with tandem mass spectrometry. Genetic analysis demonstrated 2 heterozygous missense mutations c.250G>A (p.Ala84Thr) and c.353G>T (p.Cys118Phe) in the ETFDH gene. The diagnosis of MADD was confirmed. The patient was given large dose of vitamin B2, which resulted in rapid clinical and biochemical improvement.

CONCLUSIONA common mutation c.250G>A and a novel mutation c.353G>T in the ETFDH gene were identified in the patient. The pathogenic role of c.353G>T (p.Cys118Phe) deserves further study. Early diagnosis of MADD and appropriate therapy is crucial for the prognosis.

Objective To explore the risk factors of depression after percutaneous coronary intervention ( PCI ) in patients with coronary heart disease and to provide the basis for clinical nursing intervention . Methods Totals of 300 patients after percutaneous coronary intervention , treated in our hospital from September 2012 to September 2013 were surveyed using the Beck Self Rating Depression Scale ( BDI) , type D Personality Questionnaire ( DS14 ) and self-made questionnaire . According to whether the patients had depression or not , they were divided into the depression group and the non-depression group .Results The BDI score of the depression group was (11.0 ±5.2), which was significantly higher than (3.5 ±0.6) of the non-depression group (t=2.05, P<0.05).The results of univariate analysis showed that gender , age, type D personality , heart function , exercise habits , smoking history , emergency admission , disease diagnosis , personal income and household income were the influence factors of depression after PCI .Further multivariate analysis results showed that age , type D personality , disease diagnosis and exercise habits were the independent risk factors of depression after PCI .Conclusions The age, type D character, unstable angina pectoris and no exercise can significantly increase the risk of depression after PCI of coronary heart disease patients .It is important to give targeted interventions to the risk factors in order to reduce the possibility of depression and improve patients ’ compliance and curative effect .
