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 To study the relationship between the CT value and injury of ultrastructure in posttraumatic acute diffuse brain swelling(PADBS). Methods The change of CT value of brain tissue was analyzed at posttrauma and preoperation in 9 patients, in combination with the ultrastructure in brain parenchyma in 36 specimen taken from operations. The relationship between the descend of CT value and ultrastructure injury was analysed.Results The CT value of brain in preoperation was lower than it in posttrauma first scanning(2.5~4.3 HU).The capillary distention and stenosis and the diffuse edema in pericapillary and intercellular were observed under transmission electron microscopy(TEM). The nucleolus of neuronal cells displaced to membrane or disappeard. Chromation agglutionation, nuclear membrane circuity, perinuclear diffuse lipid drops and blankspace were detected. The mitochondrion swelling, mitochondrial crest blurring or effacement, rough endoplasmic reticulum distension and its’ granules detachmen were also seen under TEM. Axolemma edema, microfilaments and microtubules derangement in axis-cylinder were found too. The similar phenomena existed in astrocyte.Conclusion The descent of CT value in PADBS was relevant to the aggravation of vasogenic cerebral edema, cytotoxic cerebral edema and ultrastructure injury in brain parenchyma.
