Objective:To investigate the association of blood lipids and body mass index (BMI) with hyperuricemia (HUA) in the elderly.Methods:It was a cross-sectional study. A total of 114 391 elderly individuals received health examinations at primary healthcare institutions in Wujin District from January to December in 2022. The health examination included questionnaire survey, physical examination and laboratory examination. The multivariate logistic regression and restricted cubic spline (RCS) plots were used to analyze the association and dose-response relationship of blood lipid and BMI with HUA. The mediating effect model was used to explore the mediation effect of BMI on the association between blood lipid and HUA.Results:Among the 112 415 subjects, 18 506 (16.46%) were checked with HUA. After adjusting for relevant confounders, total cholesterol (TC) ( OR=1.20, 95% CI: 1.16-1.23), triglyceride (TG) ( OR=1.46, 95% CI: 1.44-1.49), high density lipoprotein cholesterol (HDL-C) ( OR=0.74, 95% CI: 0.73-0.76), low density lipoprotein cholesterol (LDL-C) ( OR=1.14, 95% CI: 1.12-1.15) and BMI ( OR=1.42, 95% CI: 1.39-1.44) were all associated with HUA (all P0.05). The RCS analysis revealed that TG, HDL-C, and LDL-C each exhibited a nonlinear dose-response relationship with HUA, the inflection points was 3.00 mmol/L, 1.57 mmol/L and 2.50 mmol/L, respectively (all P-nonlinear0.001). The results of interaction showed that there were additive interaction between high TC( S=1.27 , 95% CI: 1.17-1.37), high TG( S=1.32 , 95% CI: 1.25-1.40), high LDL-C( S=1.23 , 95% CI: 1.14-1.34) and overweight/obesity with HUA (all P0.05). The results of mediation effect analysis showed that the mediation effect of BMI on the association between blood lipids (HDL-C, LDL-C, TG and TC) and HUA, from high to low, were as follows: 22.5% (95% CI: 20.8%-24.2%), 13.9% (95% CI: 12.0%-16.2%), 13.5% (95% CI: 12.7%-14.4%) and-3.9% (95% CI:-6.6%--1.8%). Conclusion:The blood lipid levels and BMI are positively correlated with HUA in the elderly.

Objective To compare the clinical efficacy of PCI with radial artery approach and bra-chial artery approach in acute myocardial infarction(AMI).Methods A retrospective analysis was performed on 173 AMI patients undergoing PCI in Department of Cardiology of Affiliated Hospi-tal of Chengde Medical College from September 2022 to September 2024.According to surgical ap-proach,they were divided into the radial artery group(97 cases)and the brachial artery group(76 cases).The X-ray exposure rate,puncture time,operation time and total hospital stay were observed in the two groups,and the puncture success rate,postoperative complication rate and incidence of 30-day cardiovascular adverse events were compared between the two groups.Results There were statistical differences in puncture time,operation duration and length of hospital stay between the two groups(P＜0.05,P＜0.01).The brachial artery group had a higher puncture success rate than the radial artery group(94.7％vs 90.7％,P=0.390),while the radial artery group had a higher incidence of postoperative complications,adverse vascular events due to coro-nary heart disease(P＜0.05,P＜0.01).Conclusion Both radial artery approach and brachial artery approach for PCI can effectively treat AMI patients.Compared with transradial approach,transbrachial approach can effectively improve the success rate of surgery,reduce postoperative complications and the occurrence of cardiovascular adverse events within 30 d of follow-up.

Caloric restriction(CR)and intermittent fasting(IF)are two dietary intervention strategies that have garnered increasing attention for their potential role in regulating inflammation and metabolic disorders.With the widespread adoption of high-calorie diets and sedentary lifestyles,the incidence of metabolic diseases such as obesity,type 2 diabetes,and cardiovascular diseases has risen significantly,posing major public health challenges.This review explores how CR and IF impact inflammation reduction and metabolic health improvement through mechanisms such as metabolic reprogramming,autophagy activation,and inhibition of inflammatory pathways.Notably,both strategies have shown promising intervention effects in inflammatory diseases like multiple sclerosis and systemic lupus erythematosus.Additionally,CR and IF demonstrate positive effects in the metabolic regulation of obesity,diabetes,and cardiovascular diseases.Despite their clinical potential,long-term adherence and safety remain key challenges for widespread implementation.Future research should focus on personalized interventions and the integration of multiple therapeutic approaches to further validate the clinical value of CR and IF.In summary,CR and IF offer novel,non-pharmacological strategies for managing chronic diseases,presenting significant potential for future clinical application.

Objective:To investigate the relationship between the expression level of long non-coding RNA transforming growth factor β2-antisense RNA1 (lncRNA TGFB2-AS1) and placental spiral artery recasting in the placenta of preeclampsia.Methods:A total of 108 pregnant women with severe preeclampsia who were hospitalized in Zaozhuang Maternal and Child Health Hospital and delivered by cesarean section from Oct. 2019 to Jun. 2021 were selected as the research objects, and they were divided into the late-onset preeclampsia group (late-onset severe preeclampsia pregnant women, 56 cases) and early-onset preeclampsia group (early-onset severe preeclampsia pregnant women, 52 cases) ; at the same time, 58 normal pregnant women were selected as the normal pregnancy group. The general data of pregnant women were collected, such as age, systolic blood pressure and diastolic blood pressure. Real-time fluorescent quantitative PCR (qRT-PCR) method was used to detect the expression level of lncRNA TGFB2-AS1 in placental tissues, a scanning electron microscope was used to measure the lumen area and wall thickness of spiral arteries. Pearson correlation analysis method was used to analyze the correlation between the level of lncRNA TGFB2-AS1 in the placenta tissue and the thickness of the spiral artery wall and the area of the lumen of pregnant women with early-onset and late-onset severe preeclampsia.Results:The tube wall thickness [ (119.69±8.31) μm], systolic blood pressure [ (162.86±4.94) mmHg], diastolic blood pressure [ (103.09±2.35) mmHg], and 24-hour urine protein [ (2.17±0.31) g/24 h] in the early preeclampsia group were higher than those in the late preeclampsia group [ (101.04±5.78) μm, (146.95±6.43) mmHg, (92.13±4.74) mmHg, (1.62±0.23) g/24 h] and the normal pregnancy group [ (99.82±5.56) μm, (116.42±9.31) mmHg, (74.25±6.74) mmHg, (0.06±0.02) g/24 h], the placental tissue lncRNA TGFB2-AS1 level (0.62±0.16), lumen area [ (133.74±20.16) μm 2], gestational week of delivery [ (32.15±1.74) weeks], weight of the newborns [ (2.25±0.26) g] were lower than those in the late-onset preeclampsia group [ (0.99±0.21), (185.49±22.75) μm 2, (36.14±1.59) weeks, (3.37±0.32) g] and the normal pregnancy group [ (1.02±0.23), (186.42±23.71) μm 2, (38.19±1.56) weeks, (3.42±0.37) g] ( P<0.05). The systolic blood pressure, diastolic blood pressure, and 24-hour urine protein in the late preeclampsia group were higher than those in the normal pregnancy group, gestational week of delivery was lower than the normal pregnancy group ( P<0.05). Placental tissue lncRNA TGFB2-AS1 of pregnant women with early-onset severe preeclampsia was positively correlated with the lumen area, and negatively correlated with the thickness of the tube wall ( P<0.05). There was no correlation between lncRNA TGFB2-AS1 and the lumen area and wall thickness in the placental tissue of pregnant women with late-onset severe preeclampsia ( P>0.05) . Conclusion:The lncRNA TGFB2-AS1 expression in the placenta tissue of pregnant women with early-onset severe preeclampsia is abnormally low, which may be related to the insufficient recasting of the placental spiral artery.

Objective To compare the effects of smoking and non smoking on postoperative pain of laparoscopic cholecystectomy. Methods Sixty patients having underwent selective laparoscopic cholecystectom were divided into smoking group and non smoking group by random digits table with 30 cases each. In smoking group, 14 cases quitted smoking within 1 week before operation. The Fagerstrom test of nicotine dependence (FTND) was evaluated before operation in smoking group, and FTND ≥ 6 scores was in 11 cases. The visual analog score (VAS), Bruggrmarm comfort score (BCS), sedation-agitation score (SAS), immediately, 15 min, and 30 min after entering postanesthesia care unit (PACU) and leaving PACU was evaluated. The operation time, anesthesia time, wake up time, extubation time, PACU time, using rate of remedial measures and untoward reaction were recorded. Results There were no statistical differences in operation time, anesthesia time, wake up time, extubation time, SAS and incidence of untoward reaction between 2 groups (P>0.05). The PACU time and using rate of remedial measures in smoking group were significantly higher than those in non smoking group:(39.7 ± 5.1) min vs. (31.3 ± 6.1) min and 30.0% (9/30) vs. 0, and there were statistical differences (P<0.05). The VAS immediately, 15 min and 30 min after entering PACU and leaving PACU in smoking group was significantly higher than that in non smoking group: (2.90 ± 0.85) scores vs. (1.00 ± 0.83) scores, (2.70 ± 0.47) scores vs. (0.73 ± 0.69) scores, (2.60 ± 0.56) scores vs. (1.13 ± 0.73) scores, (2.23 ± 0.57) scores vs. (1.13 ± 0.73) scores; and the BCS was significantly lower than that in non smoking group:(1.80 ± 0.61) scores vs. (2.90 ± 0.99) scores, (1.90 ± 0.31) scores vs. (2.87 ± 1.00) scores, (2.10 ± 0.31) scores vs. (2.47 ± 0.82) scores, (2.17 ± 0.38) scores vs. (2.47 ± 0.82) scores, and there were statistical differences (P<0.05). The VAS immediately after entering PACU in patients of FTND ≥ 6 scores was significantly higher than that in patients of FTND<6 scores:(3.6 ± 0.7) scores vs. (2.5 ± 0.7) scores, the BCS was significantly lower than that in patients of FTND <6 scores:(1.5 ± 0.5) scores vs. (2.0 ± 0.6) scores, and there were statistical differences (P<0.05). The VAS immediately after entering PACU in patients of non- quit smoking was significantly higher than that in patients of quit smoking: (3.4 ± 0.7) scores vs. (2.4 ± 0.6) scores, and there were statistical differences (P<0.05). Conclusions Smokers have more severe postoperative pain in laparoscopic cholecystectomy and higher postoperative opioid requirement than nonsmokers. Quit smoking before surgery will reduce postoperative pain and related complications. Appropriate increase of analgesic drugs can prevent postoperative pain in patients with smoking.

Objective To investigate the effect of CaMK Ⅱ expression on apoptosis of rat hepatocytes BRL-3A.Methods Rat BRL-3A cells were stable passage were cultured.The CaMK Ⅱ γ protein (LV-CaMK Ⅱ γ group) and CaMK Ⅱ γshRNA (shRNA group) lentiviral expression systems were constructed.The corresponding blank vectors (LV-NC group and shRNA-NC group) and normal saline (CON group) were perfused into the control groups.The expression levels of CaMK Ⅱ,Cyt C and MF proteins were detected by Western blotting,and the apoptosis rate of BRL-3A cells was measured by Tunel method.Results The protein expression of CaMK Ⅱ,Cyt C and AIF in LV-CaMK Ⅱ γ group was significantly higher than that in CON group (P＜0.05).The protein expression of CaMK Ⅱ,Cyt C and AIF in shRNA group was significantly lower than that in CON group (P＜ 0.05).There was no significant difference among CON group,LV-NC group and shRNA-NC group (P＞0.05).At the same time point,the apoptosis rate of hepatocytes in LV-CaMK Ⅱ γ group was significantly higher than that in CON group (P＜0.05).At the same time point,the apoptosis rate of hepatocytes in shRNA group was significantly higher than in CON group (P＜0.05).There was no significant difference in the apoptosis of hepatocytes among CON group,LV-NC group and shRNA-NC group (P＞0.05).Conclusion The specific CaMK Ⅱ signaling pathway can inhibit the apoptosis of BRL-3A cells,while the enhanced CaMK Ⅱ signaling pathway promotes the apoptosis of BRL-3A cells.

PURPOSE: The aim of our study was to explore the relationships between the M2 isoform of pyruvate kinase (PKM2) and the sensitivity of human non-small cell lung cancer (NSCLC) cells to docetaxel in vitro. MATERIALS AND METHODS: With the method of plasmid transfection, we silenced the expression of PKM2 successfully in A549 and H460 cells. Western blotting and real-time PCR were applied to detect PKM2 expression at protein and gene levels. Cell viability was examined by CCK8 assay. Cell cycle distribution and apoptosis were examined by flow cytometry. P21 and Bax were detected. RESULTS: Expression of PKM2 mRNA and protein were significantly decreased by shRNA targeting PKM2. Silencing of PKM2 increased docetaxel sensitivity of human NSCLC A549 and H460 cells in a collaborative manner, resulting in strong suppression of cell viability. The results of flow cytometric assays suggested that knockdown of PKM2 or docetaxel treatment, whether used singly or in combination, blocked the cells in the G2/M phase, which is in consistent with the effect of the two on the expression of p21. Cells with PKM2 silencing were more likely to be induced into apoptosis by docetaxel although knockdown of PKM2 alone can't induce apoptosis significantly, which is in consistent with the effect of the two on Bax expression. CONCLUSION: The results suggest that PKM2 knockdown could serve as a chemosensitizer to docetaxel in non-small lung cancer cells through targeting PKM2, leading to inhibition of cell viability, increase of cell arrest of G2/M phase and apoptosis.
