Objective To explore the impact of a“one-week”staged multivessel percutaneous coronary intervention (PCI) versus culprit-only PCI on deaths and major adverse cardiac events (MACE). Methods We retrospectively analyzed 447 patients with multivessel disease who experienced a ST-segment elevation myocardial infarction (STEMI) within 12 h before undergoing PCI between July 26, 2008 and Septem-ber 25, 2011. After completion of PCI in the infarct artery, 201 patients still in the hospital agreed to undergo PCI in non-infarct arteries with more than 70%stenosis for a“one-week”staged multivessel PCI. A total of 246 patients only received intervention for the culprit vessel. Follow-up ended on September 9, 2014. This study examined the differences in deaths from any cause (i.e., cardiac and noncardiac) and MACE between the two treatment groups. Results Compared to a culprit-only PCI treatment approach, the“one-week”staged multivessel PCI was strongly associated with greater benefits for 55-month all cause death [41 (16.7%) vs.13 (6.5%), P=0.004] and MACE [82 (33.3%) vs. 40 (19.9%), P=0.002] rates. In addition, there were significant differences in the number of myocardial infarctions [43 (17.5%) vs. 20 (10.0%), P=0.023], coronary-artery bypass grafting [CABG;20 (8.1%) vs. 6 (3.0%), P=0.021], and PCI [31 (12.6%) vs. 12 (6.0%), P=0.018]. Patients undergoing culprit-only PCI compared to“one-week”PCI had the same number of stent thrombosis events [7 (2.8%) vs. 3 (1.5%), P=0.522]. Conclusions Compared to a culprit-only PCI treatment approach,“one-week”staged multi-vessel PCI was a safe and effective selection for STEMI and multi-vessel PCI.

Objective To explore the factors relating to serum lutein level in elderly patients with early age-related macular degeneration (AMD).Methods 102 early AMD patients diagnosed by international diagnostic criteria were selected.The level of serum lutein was measured by HPLC,and dietary intake was estimated by food-frequency questionnaire (FFQ).The factors relating to serum lutein level were analyzed by Pearson correlation and multiple regression analysis models.Results Serum lutein level was higher in female AMD patients than in male AMD patients [(0.33±0.31) μmol/L vs.(0.21 ±0.19) μmol/L,t=2.21,P＜0.05].Serum lutein level was positively correlated with dietary lutein (r=0.49,P＜ 0.001),but not correlated with age,BMI,and other nutrient intake after adjustment for caloric intake.Dietary lutein was mainly from corn,spinach,leeks,eggs,chrysanthemum,pumpkin,broccoli,lettuce,asparagus and peas.Intakes of spinach,pumpkin,asparagus were significantly associated with serum lutein level.Conclusions Elderly patients with AMD should increase the intakes of lutein-rich vegetables to increase the serum lutein level.

OBJECTIVEMitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) is a progressive, multisystem affected mitochondrial disease associated with a number of disease-related defective genes. MELAS has unpredictable presentations and clinical course, and it can be commonly misdiagnosed as encephalitis, cerebral infarction, or brain neoplasms. This review aimed to update the diagnosis progress in MELAS, which may provide better understanding of the disease nature and help make the right diagnosis as well.

DATA SOURCESThe data used in this review came from published peer review articles from October 1984 to October 2014, which were obtained from PubMed. The search term is "MELAS".

STUDY SELECTIONInformation selected from those reported studies is mainly based on the progress on clinical features, blood biochemistry, neuroimaging, muscle biopsy, and genetics in diagnosing MELAS.

RESULTSMELAS has a wide heterogeneity in genetics and clinical manifestations. The relationship between mutations and phenotypes remains unclear. Advanced serial functional magnetic resonance imaging (MRI) can provide directional information on this disease. Muscle biopsy has meaningful value in diagnosing MELAS, which shows the presence of ragged red fibers and mosaic appearance of cytochrome oxidase negative fibers. Genetic studies have reported that approximately 80% of MELAS cases are caused by the mutation m.3243A>G of the mitochondrial transfer RNA (Leu (UUR)) gene (MT-TL1).

CONCLUSIONSMELAS involves multiple systems with variable clinical symptoms and recurrent episodes. The prognosis of MELAS patients depends on timely diagnosis. Therefore, overall diagnosis of MELAS should be based on the maternal inheritance family history, clinical manifestation, and findings from serial MRI, muscle biopsy, and genetics.

Objective To investigate the sodium and potassium disturbances in 9870 elderly inpatients and to analyze their risk factors.Methods Clinical data of sodium and potassium levels and the possible risk factors were collected in the elderly inpatients from a single center.The incidence of sodium and potassium disturbances and their risk factors were analyzed by multiple Logistic regression,and the correction of the imbalance was investigated.Results A total of 6027(61.6％)times of sodium and potassium disturbances were found in the 9870 elderly inpatients on admission and during hospitalization,and the total incidence of this disturbances was 61.6％.The incidences of hyponatremia,hypokalemia,hypernatremia and hyperkalemia were 27.9％ (2729/6027),9.7％ (951/6027),15.4％(1506/6027) and 8.6％ (841/6027),respectively.Heart failure was the common risk factor for the two electrolyte disturbances.T2DM caused hyponatremia,hypokalemia and hypernatremia.Among the medication risk factors,diuretics were the common risk factor for various electrolyte disturbances.Patients taking antiepileptics,antidementia drugs,antidepressants and benzodiazepines were more likely to have hyponatremia.The correction rate of mild,moderate and severe hyponatremia/ hypokalemia were 79.2％(1253/1582),68.1％ (535/786),45.1％ (163/361) and 79.5％(776/976),66.4％(217/327),40.1％(81/203),respectively.The time for the correction of the above degrees of hyponatremia/ hypokalemia were(3.7±2.7) d,(4.1±2.3) d,(8.9±1.6) d and(2.5± 1.4) d,(3.2 ± 1.5) d,(6.1 ± 1.2) d.The supplement amounts of sodium chloride and potassium chloride were(5.98±3.67) g,(9.45±3.02) g,(10.26±1.32) g and(2.23±0.93) g,(5.12± 1.53) g,(8.07 ± 2.46) g,respectively.Conclusions The incidences of electrolyte disturbances are high in elderly inpatients with combined diseases and application of various drugs,and the correction of disturbances is difficult.More attention should be paid to the electrolyte disturbances,which should be corrected positively.

Objective To investigate the prevalence of hypertension among adult residents in Mongolian region of Hulunbeier. Methods A total of 1536 adult residents were selected by using cluster sampling method, and 1496 completed the questionnaire survey. Blood pressure was measured for each participant. Results The prevalence of hypertension was 31.1%. Higher prevalence of hypertension was found in male ( 42. 0% vs 24. 5%, P ＜ 0. 05 ) and the elderly. No statistically significant difference of prevalence of hypertension was investigated in different nationalities (P ＞ O. 05 ). Conclusion The prevalence of hypertension among adult residents in Mongolian region of Hulunbeier is relatively higher.
