Abstract To understand the relationship between cardiovascular disease (CVD) and adverse childhood experiences (ACEs), the present review aims to describe the burden and influencing factors of CVD, epidemiological characteristics and burden of ACEs, current research on the relationship between ACEs and CVD, and the mechanism of ACEs leading to CVD. It is proposed that further assessment of the relationship is warranted through identifying blood biomarkers, conducting prospective cohort studies and intervention studies. Such efforts would provide valuable scientific insights for primary prevention strategies for cardiovascular disease.

Purpose: This Phase II trial was objected to evaluate the efficacy and safety of adding fulvestrant to neoadjuvant chemotherapy in patients with estrogen receptor (ER)+/human epidermal growth factor receptor 2 (HER2)– locally advanced breast cancer (LABC). Additionally, the study aimed to investigate the association of 16α-18F-fluoro-17β-fluoroestradiol (18F-FES) positron emission tomography (PET)–computed tomography (CT) and metabolites with efficacy. Materials and Methods: Fulvestrant and EC-T regimen were given to ER+/HER2– LABC patients before surgery. At baseline, patients received 18F-FES PET-CT scan, and plasma samples were taken for liquid chromatography–mass spectrometry analysis. The primary endpoint was objective response rate (ORR). Secondary endpoints included total pathologic complete response (tpCR) and safety. Results: Among the 36 patients enrolled, the ORR was 86.1%, the tpCR rate was 8.3%. The incidence of grade ≥ 3 treatment-emergent adverse events was 22%. The decrease in ER value in sensitive patients was larger than that in non-sensitive patients, as was Ki-67 (p < 0.05). The maximum standardized uptake value, mean standardized uptake values, total lesion ER expression of 18F-FES PET-CT in sensitive patients were significantly higher than those in non-sensitive patients (p < 0.05). Moreover, these parameters were significantly correlated with Miller and Payne grade and the change in ER expression before and after treatment (p < 0.05). Thirteen differential expressed metabolites were identified, which were markedly enriched in 19 metabolic pathways. Conclusion This regimen demonstrated acceptable toxicity and encouraging antitumor efficacy. 18F-FES PET-CT might serve as a tool to predict the effectiveness of this therapy. Altered metabolites or metabolic pathways might be associated with treatment response.

Objectives:To investigate the impact of baseline non-high-density lipoprotein cholesterol(non-HDL-C)levels on new-onset cardiovascular disease(CVD)in postmenopausal women. Methods:This prospective cohort study selected 8 893 postmenopausal women who participated from 2006 to 2018 employee health examination of Kailuan Group and had complete total cholesterol(TC)and HDL-C data and no history of CVD.Participants were followed up to 31 December,2021.The primary endpoint was the occurrence of CVD or death.According to the Chinese Lipid Management Guidelines(2023),the participants were divided into non-HDL-C<4.1 mmol/L group(n=6 079),4.1 mmol/L≤non-HDL-C<4.9 mmol/L group(n=1 824)and non-HDL-C≥4.9 mmol/L group(n=990).The cumulative incidence of CVD in different groups of non-HDL-C levels was calculated using the Kaplan-Meier method and tested by log-rank analysis.Multivariate Cox regression model was used to analyze the effects of different non-HDL-C levels on CVD. Results:The mean follow-up time was(10.78±4.48)years,the cumulative incidence of CVD in different non-HDL-C level groups was 1.82%,3.24%and 2.89%,respectively.Kaplan-Meier survival curve showed a statistically significant difference in cumulative incidence among the three groups(log-rank P<0.0001).The results of Cox regression analysis showed that after adjusting for confounding factors such as age and sex,the HR(95%CI)values for CVD in the 4.1≤non-HDL-C<4.9 mmol/L group and the non-HDL-C≥4.9 mmol/L group were 1.40(1.13-1.74)and 1.35(1.03-1.78),respectively. Conclusions:High non-HDL-C levels are an independent risk factor for new-onset CVD in postmenopausal women.

Objective To analyze and compare the change of disease burden attributed to high temperature in the Chinese population in 2019 compared with 1990. Methods Based on the global burden of disease study data in 2019, the number of deaths, mortality, disability-adjusted life years (DALY) and DALY rate attributable to high temperature in Chinese population of different ages and genders in 1990 and 2019 were extracted to analyze the changing trend of disease burden attributable to high temperature exposure in Chinese population and its main causes. The Joinpoint regression model was used to analyze the trend of changes in standardized attributable DALY rates. Results Compared with 1990, the number of disease deaths attributable to high temperature in China in 2019 increased from 10 700 to 13 900, and the attributable DALY decreased from 532,200 to 276 100 person-years. The standardized mortality and DALY rates decreased by 35.25% and 65.20%, respectively. The burden attributable to high temperature was higher in males than in females, and the burden was relatively heavier in the population aged 70 and above. In 2019, chronic non-communicable diseases were the main cause of the attributable burden of high temperature exposure, and ischemic heart disease had the highest DALY burden, with an age-standardized DALY rate of 4.64/100 000. Conclusion The absolute death burden attributable to high temperature exposure in Chinese population is still increasing. It is necessary to pay more attention to high-risk groups such as men and the elderly, continue to strengthen environmental protection, and formulate relevant interventions in a targeted way to further reduce the disease burden caused by high temperature exposure.

Objective:To compare the distribution differences of serum protein electrophoresis (SPE) among different gender and age individuals, and to explore the clinical application of SPE screening monoclonal gammopathy.Methods:A retrospective analysis was conducted based on the SPE results obtained from 533 989 cases enrolled from January 2018 to December 2019 at Zhongshan Hospital Affiliated to Fudan University. Among these patients, 435 479 inpatients were from departments of hematology, nephrology, spinal surgery, endocrinology, and rheumatology and immunology; and 98 510 were apparently healthy individuals. The distributions of albumin, α1 globulin, α2 globulin, β1 globulin, β2 globulin and γ globulin in different gender and age groups (≤20, 21-30, 31-40, 41-50, 51-60, 61-70, 71-80, 81-90, ≥91 years old) were compared. A total of 10 014 cases were selected by immunofixation electrophoresis (IFE). The positive detection rates of different SPE bands and IFE bands were analyzed. The sensitivity and specificity of SPE methods were determined according to IFE results as the gold standard.Results:No significant difference was examined in the proportion of SPE bands between different genders ( P>0.05). There were statistically significant differences in the proportion of albumin bands between apparently healthy individuals and hospitalized patients at different ages (apparently healthy individuals: F=5.12, P<0.05, inpatients: F=4.18, P<0.05), and all of them decreased with the increase of age. The proportion of γ globulin bands increased with age (apparently healthy individuals: F=1.34, P<0.05; inpatients: F=1.24, P<0.05). The sensitivity of SPE was 69% (2 098/3 051), and the specificity was 97% (6 721/6 963). Compared with IFE method, the positive detection rate of monoclonal gammopathy was significantly different (χ2=5 049.94, P<0.05). The positive rate of monoclonal gammopathy in γ globulin region (21.11%, 2 114/10 014) was higher than that in β globulin region (3.28%, 328/10 014) (χ2=90.74, P<0.05) and β-γ globulin region (1.63%, 163/10 014) (χ2=44.34, P<0.05). IgG and IgM bands are common in γ globulin region. Among them, IgG-κ type accounted for 94.1% (995/1 058), IgG-λ type accounted for 94.8% (690/728), IgM-κ type accounted for 89.2% (222/249), IgM-λ accounted for 83.8% (62/74). IgA bands are common in β region, of which IgA-κ accounted for 49.8% (103/207) and IgA-λ accounted for 51.6% (149/289). The positive rate of monoclonal gammopathy of IgG-κ type was the highest (10.57%, 1 058/10 014), and the positive rate of monoclonal gammopathy of IgM-λ type was the lowest (0.74%, 74/10 014). Conclusions:With increasing age, the proportion of albumin band in SPE decreased and the proportion of γ globulin band increased. IgG and IgM type monoclonal gammopathy is mostly found in the gamma region, with a higher detection rate in IgG type. IgA type monoclonal gammopathy is mostly found in the β region, with a lower detection rate.

Objective:To investigate the characteristics and distribution of monoclonal gammopathy in clinical patients.Methods:A total of 936 171 patients (508 449 males and 427 722 females) who received capillary zone electrophoresis in Zhongshan Hospital Affiliated to Fudan University from January 2012 to December 2021 were selected, from which 14 945 patients with abnormal bands were screened as the study subjects, including 10 173 males and 4 772 females and the age 21-102 (65±13) years old. According to the age, patients were divided into 8 groups: 21-30 years old (168 cases), 31-40 years old (405 cases), 41-50 years old (1 326 cases), 51-60 years old (3 068 cases), 61-70 years old (4 985 cases), 71-80 years old (3 288 cases), 81-90 years old (1 519 cases), and≥91 years old (186 cases). The diagnostic results of the 14 945 patients with abnormal bands were collected and were divided into tumor group (5 196 cases) and non-tumor disease group (9 749 cases) according to the presence of tumor. The distribution of abnormal bands in different gender, age, and disease groups were retrospectively analyzed. Among the 14 945 patients, 4 988 cases underwent immunofixation electrophoresis, excluding 336 negative cases and 412 cases of double clonal bands reaction, and 4 240 patients with monoclonal immunoglobulin (M protein) reaction were selected as the study subjects, including 2 794 males and 1 446 females aged 21-102 (67±12) years old. They were divided into 8 groups according to the age: 21-30 years old (18 cases), 31-40 years old (91 cases), 41-50 years old (364 cases), 51-60 years old (862 cases), 61-70 years old (1 455 cases), 71-80 years old (904 cases), 81-90 years old (486 cases), and≥91 years old (60 cases). The diagnostic results and immunoglobin subtypes (IgA-κ, IgA-λ, IgG-κ, IgG-λ, IgM-κ, IgM-λ, κ, λ) of patients were collected, and the distribution of monoclonal gammopathy in different gender, age and disease groups were retrospectively analyzed.Results:Among 936 171 patients, 14 945 cases showed abnormal bands in electropherograms with a detection rate of 1.60%; the detection rates of abnormal bands in males and females were 2.00% (10 173/508 449) and 1.12% (4 772/427 722), respectively, with a statistically significant difference ( P<0.01). There was a significant difference in the detection rate of abnormal bands among different age groups ( P<0.01); among them, the highest detection rate of abnormal band in group of ≥91 years old was 5.98%, and the ratio of male to female was 1.67∶1. Among the 14 945 cases of abnormal bands, patients aged 51-60, 61-70 and 71-80 accounted for 20.53% (3 068 cases), 33.36% (4 985 cases) and 22.00% (3 288 cases), respectively, and the differences among the age groups were statistically significant (χ 2=115.82, P<0.01). In the tumor group, the top 3 tumors with abnormal bands were plasmacytoma with 1 123 cases, lymphoma with 289 cases, and leukemia with 49 cases. The detection rate of abnormal bands in electropherograms of plasmacytoma was 89.92% (1 123/1 249), which was higher than that in lymphoma and leukemia [6.73% (289/4 296) and 6.40% (49/766), respectively, P<0.01]. Among 4 240 patients with positive M protein, the proportion of 51-60, 61-70 and 71-80 years old patients were 20.33% (862/4 240), 34.32% (1 455/4 240) and 21.32% (904/4 240), respectively, and the differences among age groups were statistically significant ( P<0.01). The results of M protein types showed that the proportion of IgG-κ type was the highest in both genders, with 32.28% (902/2 794) in males and 34.30% (496/1 446) in females. In the 21-30, 31-40, and 41-50 age groups, the proportion of IgG-λ was the highest, which were 38.89% (7/18), 36.26% (33/91) and 34.07% (124/364) in these groups respectively. However, the proportions of IgG-κ were the highest in either of the 51-60, 61-70, 71-80, 81-90 and ≥91 years old groups, which were 33.87% (292/862), 34.16% (497/1 455), 31.53% (285/904), 34.57% (168/486), 28.33% (17/60), respectively, and the differences among all age groups and gender groups had statistical significance ( P<0.01). Among patients with positive M protein in the tumor group, plasmacytoma accounted for 14.22% (603/4 240), followed by lymphoma 6.30% (267/4 240); among non-tumor diseases, M proteinemia accounted for the highest proportion (7.24%, 307/4 240), followed by pulmonary infection (5.47%, 232/4 240). Conclusions:The detection rate of abnormal bands in capillary zone electrophoresis may increase with age, and is higher in males than in females in the same age group; different malignant tumor diseases can also show abnormal bands in capillary zone electrophoresis, but they are still mainly hematological tumors. Among the positive results of M protein, 61-70 years old group accounts for the highest proportion; the most common type of monoclonal gammopathy is IgG type; in the age group of 21-50 years, the proportion of IgG-λ type is the highest; in the group of >50 years old, the proportion of IgG-κ type is the highest; in the diagnosis of positive monoclonal gammopathy, the top 3 diseases are all hematological diseases, including plasmacytoma, monoclonal gammopathies and lymphoma.

Objective To explore the mechanism underlying the anti-hemorrhoid effects of Qingji Liangxue mixture(QLM).Methods Models of acute hemorrhoid in rats were established using a croton oil preparation(COP)and glacial acetic acid.A total of 80 SD female rats were randomly divided into two major groups:the COP group and the glacial acetic acid group,each consisting of 40 rats.In the COP group,rats were further randomly assigned to the following subgroups:control group 1(group CA),model group 1(group CB),low-dose QLM group 1-1(group CC),high-dose QLM group 1-2(group CD),and diosmin group 1(group CE),with eight rats in each subgroup.In the glacial acetic acid group,rats were randomly divided into the following subgroups:control group 2(group GA),model group 2(group GB),low-dose QLM group 2-1(group GC),high-dose QLM group 2-2(group GD),and diosmin group 2(group GE),with eight rats in each subgroup.Except for the control groups,all other subgroups were treated with COP or glacial acetic acid then treated with various drugs for 7 days.HE staining was used to observe anorectal histomorphology induced by COP and glacial acetic acid.ELIS As were used to measure serum levels of IL-6 and TNF-α induced by COP.Additionally,the area of perianal ulcers induced by glacial acetic acid was recorded.Twenty-four C57 mice were randomly divided into a control group(group A),low-dose QLM group(group B),high-dose QLM group(group C),and adrenal chromazone tablet group(group D).Results QLM significantly improved the pathological injury of animal models with similar hemorrhoids,reduced the score of pathological changes induced by COP(P＜0.05),reduced the serum levels of IL-6 and TNF-α(P＜0.05),reduced the area of perianal ulcers induced by glacial acetic acid(P＜0.05),and shortened the time of coagulation and bleeding(P＜0.05).Conclusions QLM has a good anti-hemorrhoid activity,which may be achieved by anti-inflammatory effects,hemostasis,and reducing tissue damage.

Objective To understand how warfarin inhibition is hindered by the vitamin K epoxide reductase(VKORC1)resistant mutations.Methods An electrophoretic mobility assay was conducted based on the principle that binding with warfarin resulted in changes in VKORC1 electrophoretic mobility.The activity of VKORC1 and the half maximal inhibitory concentration(ICs0)of warfarin inhibiting VKORC1 were detected by ELISA.These experiments evaluated the binding ability of VKORC1 resistant mutants to warfarin.Results With warfarin bound,VKORC1 was protected from N-ethylmaleimide(NEM)modification and showed increased electrophoretic mobility,which was dependent on an unmodified cysteine on the flexible transmembrane helix 1(TM1)of VKORC1.In-creasing the warfarin concentration could shift more VKORC1 towards the species with the fast mobility.Compared to the wildtype VKORC1,the fast mobility fraction became less or disappeared in warfarin-resistant mutants,indi-cating weakened binding of warfarin.In addition,VKORC1 mutants with the weaker electrophoretic mobility shift indicated the stronger warfarin resistant.Conclusion Weakened warfarin binding is the primary cause of warfarin resistance.
