Objective:
To investigate the value of lipid accumulation product (LAP) and visceral fat index (VAI) for prediction of metabolic syndrome (MS).
Methods:
Based on the 2018 Survey on Chronic Diseases and Risk Factors in Yantai City of Shandong Province, residents at ages of 45 years and older were sampled, and subjects' age, disease history, waist circumstance (WC), body mass index (BMI), blood pressure and blood lipid were collected to calculate LAP and VAI. MS was diagnosed with the a joint interim statement of the International Diabetes Federation Task Force on Epidemiology and Prevention; National Heart, Lung, and Blood Institute; American Heart Association; World Heart Federation; International Atherosclerosis Society; and International Association for the Study of Obesity (JIS definition) and the recommended criteria proposed by the Chinese Diabetes Society (CDS) of Chinese Medical Association (CDS criteria), and the values of LAP and VAI for MS screening were evaluated using the receiver operating characteristic (ROC) curve analysis.
Results:
Totally 9 366 subjects were enrolled, including 4 340 men (46.34%) and 5 026 women (53.66%), and had a mean age of (54.49±9.73) years. According to the CDS criteria, the prevalence of MS was 24.58%, and LAP and VAI showed areas under the ROC curve (AUC) of 0.837 (95%CI: 0.828-0.846) and 0.751 (95%CI: 0.739-0.762), sensitivities of 78.82% and 63.31% and optimal cut-off values of 44.64 and 1.86 for screening of MS. According to the JIS definition, the prevalence of MS was 35.26%, and LAP and VAI showed AUC values of 0.842 (95%CI: 0.834-0.850) and 0.790 (95%CI: 0.780-0.800), sensitivities of 75.73% and 68.42% and optimal cut-off values of 42.01 and 1.67 for screening of MS.
Conclusions
Both LAP and VAI are effective for screening MS among middle-aged and elderly residents, and LAP presents a higher accuracy than VAI.

Objective Heart transplantation is an effective treatment of end-stage heart diseases and extending the time of donor heart preservation helps to make up for the shortage of donor hearts. This study was to investigate whether high-pressured mixed gas ( HPMG) of carbon monoxide and oxygen could prolong the time of donor heart preservation and its mechanisms. Methods Forty-eight C57BL/6 male mice aged 4-6 weeks were randomly divided in-to four groups of equal number:control ( the donor heart isolated but not transplanted) , immediate transplantation ( the donor heart transplanted right after isolated) , HTK-preservation ( the donor heart preserved in histidine-tryptophan-ketoglutarate solution for 24 hours after isolated, and HPMG preservation ( the donor heart preserved in an HPMG chamber with the oxygen partial pressure of 3200 hPa and carbon monoxide partial pressure of 800 hPa for 24 hours after isolated) .Another 36 recipient mice aged 6-8 weeks were randomly assigned to receive the donor heart immediately after harvested (n=12), preserved in HTK solution (n=12), or preserved in HPMG (n=12).At 2 hours after transplantation, the status of heart re-beating and cardiac function were compared among different groups of recipient mice.At 24 hours, tissues were taken from the transplanted hearts for examination of pathologic changes by HE stai-ning, detection of the apoptosis of cardiac cells by TUNEL, and determination of the expressions of microtubule-associated protein 1 light chain 3 -Ⅱ(LC3-Ⅱ) and B cell lymphoma/leukemia-2 (Bcl-2) by Western blot. Resul ts The re-beating rates of the imme-diately transplanted and HPMG-preserved hearts were significantly higher than that of the HTK-preserved ones (P<0.05).At 2 hours after transplantation, the cardiac function scores were 2.5 (2.0-2.9), 0.8 (0.5-1.0), and 4.5 (4.0-4.5) in the immediate implantation, HPMG-preservation and HTK-preservation groups respectively, with statistically significant differences between any two groups (P<0.05).The expressions of LC3-Ⅱand Bcl-2 were 2.06 ±0.29 and 0.87 ±0.18 in the HPMG-preserved heart recipients and 1.24 ±0.20 and 2.07 ±0.32 in the immediately transplanted heart recipients, both higher than 0.13 ±0.03 and 0.19 ±0.02 in the controls and 0.16 ±0.06 and 0.26 ±0.08 in the HTK-preserved heart recipients (P<0.05), the Bcl-2 higher in the HTK-pre-served heart recipients than in the controls (P<0.05), and the LC3-Ⅱ expression higher in the HPMG-preserved heart recipients than in the immediately transplanted heart recipients (P<0.05).HE staining showed that cell edema and inflammatory cell infiltration were more obvious in the HPMG-preserved heart recipients than in the controls and immediately transplanted heart recipients but less obvious than in the HTK-preserved heart recipients.The rate of cell apoptosis was dramatically increased in the HPMG-and HTK-pre-served heart recipients ([5.04 ±1.77]%and [26.72 ±5.23]%) in comparison with the controls ([1.08 ±0.56]%) (P<0.01) and immediately transplanted heart recipients ([2.13 ±1.71]%) (P<0.01) but decreased in the HPMG as compared with the HTK-preserved heart recipients (P<0.01). Conclusion High-pressured mixed gas preservation can reduce cold ischemia-reperfu-sion injury of the donor heart, which may be associated with its promotion of autophagy, provision of energy to cells, and apoptosis of cardiocytes in the donor heart.

Objective Background and objective The Cox maze Ⅲ procedure has been considered the gold standard for the surgical treatment of atrial fibrillation (AF) and the modified Cox maze use bipolar radiofrequency ablation instead of the cut-and-sew technique,while also reducing the connecting lines in left atrium.This study was to understand whether completely isolation the posterior left atrium by increasing left atrium ablation lines can enhance the survival after modified Cox maze procedure.Methods From Jan 2009 to Dec 2009,all the patients underwent the Cox maze procedure,following the same examination,were divided into two groups (case-control): box lesion group (n =60),which is means the right and lefi pulmonary vein lesions were connected inferiorly by adding ablation lines,thereby completely isolating the posterior left atrium and the non-box lesion group (n =60).Similar interventions were given during the perioperative periods.Comparing the risk factors before surgeries,then follow-up was 100% complete,and the mean follow-up was 9 ± 8.4 months.Results Except the box lesion had long time of extracorporeal circulation,the characteristics of the 2 groups were similar because there were no differences in age,AF duration,left atrial diameter,left ventricular ejection fraction or homochronous operation between the groups and there was no operative death.No patient was lost to follow-up.In the mean follow-up duration,a patient was died of intracerebral hemorrhage at 2 months postoperationly in the box lesion group and a patient suffered from stroke at 12 months postoperationly in the non-box lesion.The overall freedom from AF recurrence was higher in the box lesion group at 1 (70% vs 51.2%,P =0.039) and 3 (78.3% vs 60%,P =0.030) months.While it was 80% vs 71.7% (P =0.286) at 6 months.Eight patients wrere readmitted because of the recurrence of AF,4 and 2 patients underwent catheter ablation in box and non-box group respectively,one patient in each group underwent electrical conversion.After treatment,all of the patients were recovered to sinus rhythm and continued to take cordarone.Conclusion Compared to the single connecting between right and left pulmonary vein,isolating the entire posterior left atrium by creating a box lesion showed higher freedom from AF in the earlier months (1-3months).However,half a year after the surgery,there were no significant differences between the two groups.
