Objective:To investigate the effect of five-element music therapy combined with meridian-based acupoint massage timed according to qi circulationon on negative emotions and sleep quality in older adults with chronic heart failure. Methods:A total of 112 older adult patients with chronic heart failure who received treatment at The Affiliated Hospital of Hangzhou Normal University between January 2022 and June 2023 were included in this study. They were randomly divided into a control group ( n = 56) and a study group ( n = 56) using the random number table method. Based on conventional treatment, the control group received five-element music therapy, while the intervention group underwent a combination of five-element music therapy and meridian-based acupoint massage timed according to qi circulation. Before and after the intervention, a comparison was made between the two groups in terms of the scores of the Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), Pittsburgh Sleep Quality Index (PSQI), and various dimensions of the Minnesota Living with Heart Failure Questionnaire (MLHFQ). Additionally, the sleep outcome and patient satisfaction were also compared between the two groups. Results:After intervention, the scores of the HAMA and HAMD in the study group were (11.29 ± 2.48) points and (12.48 ± 3.36) points, respectively. In contrast, the control group had scores of (15.93 ± 3.35) points and (16.50 ± 4.32) points, respectively. After intervention, the scores of the HAMA and HAMD scales in both the study and control groups demonstrated a significant reduction in comparison with their respective pre-intervention scores [study group: (20.13 ± 5.18) points, (23.95 ± 8.97) points, control group: (19.36 ± 5.45) points, (23.79 ± 7.61) points, t = 15.35, 10.24, 5.65, 8.93, all P < 0.001). After intervention, the scores of the HAMA and HAMD scales in the study group were significantly lower than those in the control group ( t = -8.34, -5.49, both P < 0.001). After intervention, the scores of the PSQI in the study and control groups were (7.05 ± 0.96) points and (9.91 ± 1.28) points, respectively. After intervention, the scores of PSQI in both the study and control groups demonstrated a significant reduction compared with their respective pre-intervention scores [study group: (12.98 ± 2.21) points, control group: (12.50 ± 2.48) points, t = 24.68, 9.79, both P < 0.05]. After intervention, the score of the PSQI in the study group was significantly lower than that in the control group ( t = 13.34, P < 0.05). Based on the scores across various dimensions of the MLHFQ, it was observed that after intervention, the scores of emotional, physical, and other domains in both the study and control groups [study group: (9.36 ± 2.29) points, (16.95 ± 3.80) points, (18.50 ± 2.33) points; control group: (12.93 ± 2.00) points, (19.98 ± 3.98) points, (20.04 ± 2.24) points] decreased significantly compared with their pre-intervention scores [study group: (15.57 ± 1.55) points, (26.23 ± 4.63) points, (21.18 ± 2.50) points, control group: (16.09 ± 1.87) points, (25.32 ± 4.40) points, (21.57 ± 2.69) points, t = 21.66, 18.55, 8.44, 11.29, 11.73, 4.61, all P < 0.001]. After intervention, the scores of emotional, physical, and other domains in the study group were significantly lower than those in the control group ( t = -8.79, -4.13, -3.56, all P < 0.05). Patient satisfaction in the study group was superior to that that in the control group [98.21% (55/56) vs. 87.50% (49/56), χ2 = -3.09, P < 0.05]. Total effective rate of intervention on sleep in the study group was significantly higher than that in the control group [92.86% (52/56) vs. 78.57% (44/56), χ2 = -2.09, P < 0.05]. Conclusion:Five-element music therapy combined with meridian-based acupoint massage timed according to qi circulationon in the treatment of chronic heart failure in older adults can effectively alleviate negative emotions, improve the quality of life and sleep, and increase patient satisfaction with nursing care.

Objectives:This study aims to investigate the association between cumulative fasting blood glucose(FBG)and presence of coronary artery calcification(CAC). Methods:A total of 1 113 participants were recruited from the Beijing Community-based Cohort of Atherosclerosis.Anthropometric measurements and laboratory examinations including FBG were performed in 1998,2008-2009 and 2013-2014 respectively,and coronary CT scan was performed in 2013-2014.Participants were classified into 4 groups according to the level of cumulative FBG(10-year weighted cumulative value of at least 2 FBGs):<50.0 mmol/L group(n=495),50.0-55.9 mmol/L group(n=345),56.0-69.9 mmol/L group(n=176),and≥70.0 mmol/L group(n=97).CAC score>0 was defined as presence of CAC.Multivariable logistic regression model was applied to analyze the impact of cumulative FBG exposure on the risk of CAC,and subgroup analyses were conducted according to factors such as sex and age. Results:The mean age of enrolled participants was(59.7±6.4)years,523(47.0%)were male and 478(42.9%)had CAC.The proportion of subjects with CAC increased with the increment of cumulative FBG.Compared with the<50.0 mmol/L group,the multivariable-adjusted OR(95%CI)for CAC in the 50.0-55.9 mmol/L group,56.0-69.9 mmol/L group,and≥70.0 mmol/L group were 1.43(1.04-1.98),1.92(1.24-2.99)and 2.79(1.35-5.77),respectively(Ptrend<0.05).The risk for CAC increased by 34%per 10 mmol/L increase in cumulative FBG,with OR(95%CI)of 1.34(1.12-1.59).There was no statistically significant difference in the risk of CAC presence for each 10 mmol/L increase in cumulative FBG level between the subgroups(all P≥0.05). Conclusions:Elevated cumulative FBG is a risk factor for the prevalence of CAC,indicating the importance of maintaining healthy FBG in preventing the occurrence of CAC.

Objective:To evaluate the new model of group screening combined with opportunistic screening for the diagnosis and treatment of gastric cancer.Methods:Group screening combined with opportunistic screening was used for gastric cancer screening. (1) Group screening. Cluster sampling was used to screen gastric cancer by endoscopy in high-risk population (aged 40-<70 years) of rural residents in Weihai from July 2017 to December 2020, and biopsy was obtained for histopathology if necessary. Main collection parameters included the detection rate of advanced gastric cancer, early gastric cancer and high-grade intraepithelial neoplasia (HGIN). (2) Opportunistic screening. The changes of the detection rates of early gastric cancer in opportunistic screening in 2 hospitals in Weihai area were observed during the same period of time.Results:(1) In group screening, from July 2017 to December 2020, the first batch of 8 000 cases of gastric cancer screening were completed. The cases of advanced gastric cancer, early gastric cancer and HGIN were 36, 28, and 62, respectively. The detection rates of gastric cancer and early gastric cancer were 0.80% (64/8 000) and 43.75% (28/64), respectively. The proportion of early gastric cancer+HGIN who received endoscopic submucosal dissection (ESD) was 77.78% (70/90), and the rate of curative resection was 100.00%(70/70). (2) Opportunistic screening: from July 2017 to December 2020, the annual early gastric cancer detection rates in opportunistic screening in Wendeng District Traditional Chinese and Western Medicine Hospital were 16.67% (1/6), 20.00% (3/15), 23.53% (4/17), and 33.33% (6/18) in the consecutive 4 years, respectively. The annual detection rates of early gastric cancer in opportunistic screening in Ru Shan Peoples Hospital were 14.74% (14/95), 23.80% (60/252), 25.49% (65/255), and 24.04% (50/208), respectively. The detection rates of opportunistic screening for early gastric cancer in hospitals in Weihai city increased year by year.Conclusion:In areas with high incidence of gastric cancer, a certain scale of group screening can lead to a wider range of opportunistic screening, resulting in the increase of the detection rate of early gastric cancer. The new model of diagnosis and treatment of gastric cancer is worth recommendation.

Objective:To investigate the distribution and related factors of lipoprotein(a) [Lp(a)] level in healthy Tajik and Kazak adults in China.Methods:A cross-sectional study was conducted from May to October 2021 and March to June 2022, and blood samples were collected from 2, 637 healthy Tajik adults [1 010 men, average age: (40.08±14.74) years; 1 627 women, average age: (38.27±12.90) years] in Tashkurgan Tajik Autonomous County and 1 911 healthy Kazak adults [720 men, average age: (42.10±12.26) years; 1 191 women, average age: (38.27±12.90) years] in Fuyun County of Xinjiang. Fasting blood glucose (FBG), creatinine (Cr), total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), and Lp(a) were measured. The distribution of Lp(a) levels in different sex and age groups was compared. The Lp(a) level of Tajik and Kazakh ethnic groups was compared by Mann-Whitney U test, and correlation factors of Lp(a) level were analyzed by multiple logistic regression. Results:The distribution of Lp(a) level in Tajik and Kazak population was skewed. Lp(a) levels of Tajik and Kazak ranged from the lowest 0.40 mg/L and 0.62 mg/L to the highest 1 229.40 mg/L and 2 108.58 mg/L, respectively, and the median Lp(a) level was 78.90 (38.60, 190.20) mg/L and 103.30 (49.57, 234.27) mg/L, respectively. Median Lp(a) level of Kazak was significantly higher than that of Tjik ( P<0.001). The median Lp(a) levels of Tajik males and females were similar: 77.45 (39.80, 187.10) mg/L and 79.90 (38.60, 192.30) mg/L ( P=0.948). The median Lp(a) levels of Kazakh males and females were also similar: 109.42 (50.49, 230.38) mg/L and 99.01 (49.11, 237.25) mg/L, respectively ( P=0.578). After pooling the data of Tajik and Kazak and adjusting for age, sex, BMI, smoking, drinking, blood pressure, blood glucose and other factors, Lp(a) level was correlated with ethnic (standard partial regression coefficient 0.066, P=0.008) and LDL-C level (standard partial regression coefficient 0.136, P<0.001). Conclusions:Lp(a) level in healthy Tajik and Kazak adults varied greatly among individuals, and Kazak residents had a higher Lp(a) level than Tajik residents. There was no significant sex difference in Lp(a) level among Tajik and Kazakh, and LDL-C and ethnicity are independent factors related to Lp(a) level.

Covalent organic nanospheres(CONs)were explored as a fiber coating for solid-phase microextraction of genotoxic impurities(GTIs)from active ingredients(AIs).CONs were synthesized by an easy solution-phase procedure at 25℃.The obtained nanospheres exhibited a high specific surface area,good ther-mostability,high acid and alkali resistance,and favorable crystallinity and porosity.Two types of GTIs,alkyl halides(1-iodooctane,1-chlorobenzene,1-bromododecane,1,2-dichlorobenzene,1-bromooctane,1-chlorohexane,and 1,8-dibromooctane)and sulfonate esters(methyl p-toluenesulfonate and ethyl p-toluenesulfonate),were chosen as target molecules for assessing the performance of the coating.The prepared coating achieved high enhancement factors(5097-9799)for the selected GTIs.The strong affinity between CONs and GTIs was tentatively attributed to T-T and hydrophobicity interactions,large surface area of the CONs,and size-matching of the materials.Combined with gas chromatography-mass spectrometry(GC-MS),the established analytical method detected the GTIs in capecitabine and imatinib mesylate samples over a wide linear range(0.2-200 ng/g)with a low detection limit(0.04-2.0 ng/g),satisfactory recovery(80.03％-109.5％),and high repeatability(6.20％-14.8％)and reproducibility(6.20％-14.1％).Therefore,the CON-coated fibers are promising alternatives for the sensitive detection of GTIs in AI samples.
