Objective:To investigate the characteristics of short-term prognostic factors in very elderly patients with acute coronary syndrome (ACS).Methods:A total of 2 912 ACS patients admitted to Shengjing Hospital of China Medical University from January 1, 2010 to October 31, 2014 and treated with percutaneous coronary intervention (PCI) were enrolled and divided into two groups according to age: very elderly group (≥75 years, 480 cases) and control group (< 75 years, 2 432 cases). The clinical data and coronary artery lesions of the included patients were detected. Major cardiovascular adverse events (MACE) occurred within 30 d after discharge were followed up and recorded. The short-term prognostic factors in very elderly patients with ACS were analyzed by Logistic regression.Results:Compared with control group, the percentage of hypertension, global registry of acute coronary events (GRACE) score, high density lipoprotein cholesterol, N-terminal pro-brain natriuretic peptide, the left main lesion ratio and Gensini score in very elderly group were higher, while the percentage of men, number of smoking, hyperlipidemia proportion, red blood cell count, white blood cell count, blood platelet count, albumin, and long term oral administration of aspirin, clopidogrel, statins, angiotensin receptor inhibitor after discharge were lower, and the differences were statistically significant ( P<0.01 or<0.05). During the follow-up period, the all-cause mortality in very elderly group was higher than that in control group: 2.5%(12/480) vs. 0.9% (21/2 432), and the difference was statistically significant ( P<0.01). Multivariate analysis showed that oral angiotensin converting enzyme inhibitor was a protective factor for elderly ACS patients after discharge ( OR = 0.046, 95% CI 0.006 to 0.383, P = 0.004). The receiver operating characteristic curve analysis showed that Gensini score ≥ 87.75 scores was a threshold value for all-cause mortality. The all-cause mortality ratio in high Gensini score (≥ 87.75 scores) group was higher than that in low Gensini score (<87.75 scores) group: 6.6% (9/137) vs. 0.9% (3/343), and the difference was statistically significant ( P<0.01). Conclusions:Very elderly patients with ACS have their own characteristics from both clinical history and prognostic factors. Patients with Gensini score of ≥ 87.75 scores should be closely observed, and drug treatment during hospitalization should be intensified if necessary. Follow-up should be strengthened for such patients, and oral drug treatment should be continued after discharge.

Objective To evaluate efficacy of healthy canteen based-nutritional health promotion so as to provide evidence for popularization and application.Methods A total of 429 college professors and administrative staffs with a healthy canteen were selected as the intervention group in 2012 in Changzhou,and another 947 counterparts without a healthy canteen were selected as the control group.Those of the intervention group was further assigned to the ≥2 times/week and＜2 times/week subgroups.Blood pressure,fatty liver,serum triglycerides,blood glucose,total cholesterol,uric acid,low-density lipoprotein cholesterol,high-density lipoprotein cholesterol and body mass index(BMI)were tested before and after the intervention.Results After the intervention,the mean serum glucose[(5.06±0.62)mmol/L],uric acid[(310.57 ± 71.79)μmol/L],total cholesterol[(4.88 ± 0.86)mmol/L],triglycerides[(1.39 ± 0.67)mmol/L]and low-density lipoprotein cholesterol[(2.51 ±0.62)mmol/L]of the intervention group were significantly decreased(t values were 7.513,2.126,2.062,3.731 and 8.891,respectively; all P＜0.05),and mean high-density lipoprotein cholesterol[(1.43±0.34)mmol/L]were significantly increased(t=-2.309,P＜0.05).After the intervention,mean serum glucose and uric acid of the control group were significantly increased(t values were-3.491 and-7.703,respectively; both P＜0.05),although there was no statistically significant difference of mean serum triglycerides,total cholesterol,low-density lipoprotein cholesterol and high-density lipoprotein cholesterol in the control group before and after the intervention(all P＞0.05).The abnormality rates of serum glucose,uric acid,total cholesterol,triglycerides,low-density lipoprotein cholesterol and BMI as well as the incidence of hypertension of the intervention group were significantly decreased after the intervention(x2 values were 4.202,3.940,4.031,7.305,59.422,4.273 and 7.385,respectively; P＜0.05).In the control group,although the abnormality rate of serum uric acid and the incidence of fatty liver were significantly inclined after the intervention(x2 values were 23.740 and 7.408,respectively; both P＜0.05),there were no significant difference of abnormal serum triglycerides,glucose,total cholesterol,low-density lipoprotein cholesterol and BMI as well as the incidence of hypertension before and after the intervention(all P＞0.05).Mean serum triglycerides[(1.15 ±0.68)mmol/L]and low-density lipoprotein cholesterol[(2.4 1±0.60)mmol/L]in the ≥2 times/ week subgroup were significantly lower than those of the＜2 times/week subgroup(t values were-4.884 and-2.513,respectively; both P＜0.05),and mean high-density lipoprotein cholesterol[(1.46±0.33)mmo]/L]of the ≥2 times/week subgroup was significantly higher than that of the＜2 times/week subgroup(t=2.032,P＜0.05).The abnormality rates of serum total cholesterol,triglyceride and low-density lipoprotein cholesterol in the ≥ 2 times/week subgroup were significantly lower than those in the＜2 times/week subgroup(x2 values were 3.963,9.947 and 4.589,respectively; all P＜0.05).Conclusion Healthy canteen based-nutritional health promotion model may provide an effective method to prevent and control the development of noncommunicable chronic diseases.

Objective:To investigate the prognostic value of infarct size (IS) in patients with acute ST-segment elevation myocardial infarction (STEMI) underwent primary percutaneous coronary intervention (PCI).Methods:A total of 104 patients with acute STEMI who underwent primary PCI treatment in Shengjing Hospital of China Medical University from February 2017 to November 2018 were included in the present study. All patients underwent cardiovascular magnetic resonance (CMR) within one week after primary PCI treatment. The subjects were followed up for two years. Major adverse cardiac events (MACE) included new onset congestive heart failure and/or recurrent nonfatal myocardial infarction and/orcardiac death. The optimal IS cutoff value for MACE was determined by receiver operating character (ROC) curve. Based on the IS cutoff value, the patients were divided into the high IS group and the low IS group. Clinical characteristics between the two groups were compared. A cox regression model was used to analyze the prognostic value of IS in acute STEMI patients treated with primary PCI for the adverse events.Results:The IS cutoff value determined by ROC curve was 13.55%. 50 patients were in the high IS group (IS≥13.55%) and 54 patients were in the low IS group (IS<13.55%). More female patients [14 cases (28.0%) vs. 6 cases (11.1%)] were in the IS group, and a higher proportion of patients in the high IS group had anterior myocardial infarction [27 cases (54.0%) vs. 16 cases (29.6%)] or microvascular obstruction [32 cases (64.0%) vs. 16 cases (29.6%)]. White blood cell counts [11.25(8.90, 13.38) ×10 9/L vs. 9.25(7.58, 11.00) ×10 9/L], troponin I levels [50.63(16.56, 76.30)μg/L vs. 16.58(2.66, 38.42)μg/L] and brain natriuretic peptide levels [178.10(79.70, 281.95)μg/L vs. 79.60(42.83, 183.90)μg/L] in the high IS group were higher than those in the low IS group ( P<0.05), and left ventricular ejection fraction [(45.15±10.65)% vs. (51.95±12.91)%] in the high IS group was lower than that in the low IS group ( P<0.05). Multivariate Cox regression analyses showed that IS was independently associated with the risk of cardiac death in patients with acute STEMI two years after primary PCI( P=0.033, HR=1.075, 95% CI1.006-1.148). Every 1% increase in IS was associated with a 7.5% increase in cardiac death. Conclusions:Infarct size, measured by CMR within one week after primary PCI, is strongly associated with cardiac death in patients with acute STEMI two years after primary PCI. IS could be used as an index for the prognosis of patients with acute STEMI.

OBJECTIVE:At present,there are a variety of treatment methods for scoliosis using specific exercise therapy,but there is a lack of comparison of efficacy between different specific exercise therapy.This article compared the effectiveness of different specific exercise therapies to treat adolescent idiopathic scoliosis through a network meta-analysis. METHODS:Domestic and foreign electronic databases of relevant studies were searched for randomized controlled trials of specific exercise therapy for adolescent idiopathic scoliosis.Search time was from January 2000 to July 2023.The literature was screened by two reviewers using RevMan 5.4 and Stata 16.0 software to extract data and assess the bias risk of of inclusion studies. RESULTS:(1)This article includes 20 randomized controlled trials with 1 377 patients.Of them,12 studies involved Schroth therapy;2 studies involved BSPTS therapy,and 6 studies involved SEAS therapy.(2)The network meta-analysis indicated that in terms of improving Cobb angle and reducing trunk rotation angle in scoliosis patients,the BSPTS therapy group and Schroth therapy group were better than the conventional control group[WMD=-4.60,95%CI(-8.37,-0.82),P<0.05;WMD=-3.37,95%CI(-4.98,-1.75),P<0.05;WMD=-3.20,95%CI(-5.50,-0.90),P<0.05;WMD=-2.13,95%CI(-3.16,-1.09),P<0.05].The Schroth therapy group performed better than the conventional control group effective in improving the International Society for Scoliosis Research-22 Questionnaire quality of life score[WMD=1.41,95%CI(0.07,2.75),P<0.05]. CONCLUSION:Given the current evidence,BSPTS therapy group and Schroth therapy group were better than the conventional control group in improving Cobb angle and reducing trunk rotation angle.In the comparison of different specific exercise therapies,BSPTS therapy can be preferred to improve Cobb angle and reduce trunk rotation angle in adolescent idiopathic scoliosis patients.In addition,Schroth therapy may be the best treatment to improve the quality of life of adolescent idiopathic scoliosis patients.Limited by the quantity and quality of the included studies,the above conclusions should be interpreted with caution and need more high-quality studies to further validation.

The widespread application of next generation sequencing (NGS) in clinical settings has enabled testing, diagnosis, treatment and prevention of genetic diseases. However, many issues have arisen in the meanwhile. One of the most pressing issues is the lack of standards for reporting genetic test results across different service providers. The First Forum on Standards and Specifications for Clinical Genetic Testing was held to address the issue in Shenzhen, China, on October 28, 2017. Participants, including geneticists, clinicians, and representatives of genetic testing service providers, discussed problems of clinical genetic testing services across in China and shared opinions on principles, challenges, and standards for reporting clinical genetic test results. Here we summarize expert opinions presented at the seminar and report the consensus, which will serve as a basis for the development of standards and guidelines for reporting of clinical genetic testing results, in order to promote the standardization and regulation of genetic testing services in China.
