Objective: To analyze the association between dietary inflammatory index (DII) and gallstone disease among middle-aged and elderly population, so as to provide the evidence for the prevention and control of gallstone disease. Methods: Baseline survey data were collected from the Shanghai Women's Health Study (SWHS) and Shanghai Men's Health Study (SMHS), including demographic information, gallstone disease prevalence and dietary habits. DII was calculated using 29 kinds of food parameters associated with common inflammatory biomarkers and food intake data of residents. A multivariable logistic regression model was used to analyze the association between dietary inflammatory index and gallstone disease. Results: A total of 132 312 individuals were included in the analysis. There were 59 627 males and 72 685 females. Among males, the median age was 53.07 (interquartile range, 9.73) years, 41 544 cases (69.67%) had an educational level of middle school, 4 463 cases (7.48%) had gallstone disease, and DII was -6.46 to 5.59. Among females, the median age was 50.27 (interquartile range, 9.05) years, 47 380 cases (65.19%) had an educational level of middle school, 8 090 cases (11.13%) had gallstone disease, and DII was -6.44 to 4.93. Multivariable logistic regression analysis showed that after adjusting for age, educational level, income level, smoking, alcohol consumption, tea consumption, physical activity and menopausal status (only for females), DII (OR=1.095, 95%CI: 1.002-1.196) was associated with an increased risk of gallston disease among males, but no statistically association was found among females (P>0.05). Conclusion DII might be associated with an increased risk of gallstone disease among middle-aged and elderly population.

Objective:To explore the interaction effect of diabetes and obesity on recurrence or anal fistula in patients with perianal abscess after simple incision and drainage.Methods:The clinical data of 163 patients with perianal abscess who underwent simple incision and drainage from Jun. 2021 to Jun. 2023 were analyzed retrospectively. The incidence of recurrence or anal fistula in 6 months after surgery was calculated. Multivariate Logistic regression model was used to analyze the influencing factors of postoperative recurrence or anal fistula. The multiplicative and additive models were used to analyze the interaction effect of diabetes and obesity on the risk of postoperative recurrence or anal fistula.Results:In 6 months after simple incision and drainage, the incidence of recurrence or anal fistula was 28.22% (46/163). Univariate analysis results showed that gender, obesity, and diabetes were related to recurrence of perianal abscess or incidence of anal fistula ( P<0.05). Multivariate Logistic regression analysis results showed that obesity ( OR=2.447, 95% CI: 1.320-4.538) and diabetes ( OR=2.162, 95% CI: 1.187-3.938) were independent risk factors for postoperative recurrence or anal fistula ( P<0.05). Interaction effect analysis found that after adjusting for confounding factors, diabetes and obesity had additive interaction effect on the risk of postoperative recurrence or anal fistula. The relative excess risk due to interaction (RERI), attribution percentage (AP), and interaction effect index (S) were 1.829 (95% CI: 0.605-3.007), 0.405 (95% CI: 0.143-0.597), and 2.098 (95% CI: 1.201-3.172), respectively. There was no multiplicative interaction effect between the two ( P>0.05) . Conclusions:Diabetes and obesity are independent risk factors for recurrence or anal fistula in patients with perianal abscess after simple incision and drainage. The two may have synergistic effect on the risk of postoperative recurrence or anal fistula.

Objectives:To analyze the status and temporal changes of disability-adjusted life year (DALY) for stomach and colorectal cancers among registered permanent residents in Changning District of Shanghai Municipality, and provide scientific basis for the prevention and treatment of stomach and colorectal cancers in this district.Methods:Using the cancer registration data of stomach and colorectal cancers from 2002 to 2019, we estimated the indices such as the DALYs, the DALY crude rates, the age-standardized DALY rates, etc. Then we used the Joinpoint regression model to calculate the average annual percent change (AAPC) and annual percent change (APC) to explore the temporal variations in different periods.Results:The DALYs of stomach and colorectal cancers in Changning District from 2002 to 2019 were 55 931 person years and 65 252 person years, respectively. The crude rates of DALY were 512.16/10 5 and 597.51/10 5, respectively. We observed a higher disease burden in men than in women, and the peak rate of DALY in stomach cancer was in the 75-79 years age group, while in colorectal cancer the rate was in the 85-years-or-older age group. Joinpoint regression analysis showed that from 2002 to 2019, the age-standardized DALY rate of stomach cancer showed a downward trend (AAPC=-3.86%, P＜0.05), while the trend of colorectal cancer was not statistically significant(AAPC=-0.08%, P＞0.05). However, the trends in the age-standardized DALY rates of colorectal cancer were different between males and females, with males showing an upward trend (AAPC=1.24%, P＜0.05) and females showing a downward trend (AAPC=-1.67%, P＜0.05). Conclusions:The DALY of stomach and colorectal cancers in Changning District of Shanghai showed a decreasing trend. Males and the middle-aged and elderly populations are still the key targets for disease prevention and control in this district.

BACKGROUND: High-grade serous ovarian cancer (HGSOC) is the biggest cause of gynecological cancer-related mortality because of its extremely metastatic nature. This study aimed to explore and evaluate the characteristics of candidate factors associated with the metastasis and progression of HGSOC. METHODS: Transcriptomic data of HGSOC patients' samples collected from primary tumors and matched omental metastatic tumors were obtained from three independent studies in the National Center for Biotechnology Information (NCBI) Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) were selected to evaluate the effects on the prognosis and progression of ovarian cancer using data from The Cancer Genome Atlas (TCGA) database. Hub genes' immune landscapes were estimated by the Tumor Immune Estimation Resource (TIMER) database. Finally, using 25 HGSOC patients' cancer tissues and 10 normal fallopian tube tissues, immunohistochemistry (IHC) was performed to quantify the expression levels of hub genes associated with International Federation of Gynecology and Obstetrics (FIGO) stages. RESULTS: Fourteen DEGs, ADIPOQ , ALPK2 , BARX1 , CD37 , CNR2 , COL5A3 , FABP4 , FAP , GPR68 , ITGBL1 , MOXD1 , PODNL1 , SFRP2 , and TRAF3IP3 , were upregulated in metastatic tumors in every database while CADPS , GATA4 , STAR , and TSPAN8 were downregulated. ALPK2 , FAP , SFRP2 , GATA4 , STAR , and TSPAN8 were selected as hub genes significantly associated with survival and recurrence. All hub genes were correlated with tumor microenvironment infiltration, especially cancer-associated fibroblasts and natural killer (NK) cells. Furthermore, the expression of FAP and SFRP2 was positively correlated with the International Federation of Gynecology and Obstetrics (FIGO) stage, and their increased protein expression levels in metastatic samples compared with primary tumor samples and normal tissues were confirmed by IHC ( P = 0.0002 and P = 0.0001, respectively). CONCLUSIONS This study describes screening for DEGs in HGSOC primary tumors and matched metastasis tumors using integrated bioinformatics analyses. We identified six hub genes that were correlated with the progression of HGSOC, particularly FAP and SFRP2 , which might provide effective targets to predict prognosis and provide novel insights into individual therapeutic strategies for HGSOC.

Chronic inflammation is critical in the onset and progression of atherosclerosis (AS). The lipopolysaccharide (LPS) level in the circulation system is elevated in AS patients and animal models, which is correlated with the severity of AS. Inspired by the underlying mechanism that LPS could drive the polarization of macrophages toward the M1 phenotype, aggravate inflammation, and ultimately contribute to the exacerbation of AS, LPS in the circulation system was supposed to be the therapeutic target for AS treatment. In the present study, polymyxin (PMB) covalently conjugated to PEGylated liposomes (PLPs) were formulated to adsorb LPS through specific interactions between PMB and LPS. In vitro, the experiments demonstrated that PLPs could adsorb LPS, reduce the polarization of macrophages to M1 phenotype and inhibit the formation of foam cells. In vivo, the study revealed that PLPs treatment reduced the serum levels of LPS and pro-inflammatory cytokines, decreased the proportion of M1-type macrophages in AS plaque, stabilized AS plaque, and downsized the plaque burdens in arteries, which eventually attenuated the progression of AS. Our study highlighted LPS in the circulation system as the therapeutic target for AS and provided an alternative strategy for AS treatment.

Abstract: Objective　To understand the epidemiological characteristics of the migratory bird population with hypertension in Hainan and to provide a basis for the health management of the migratory bird population. Methods　One hundred and eighty migratory birds with hypertension who had lived in in the Mangrove Bay community of Chengmai, Hainan for 3 months or more were selected as the study population. Demographic data, including gender, age, ethnicity, occupation, medication use, family history of hypertension, hometown living environment, Hainan living environment (presence of water area and greenbelt around the residence, type of water area and greenbelt), smoking and alcohol consumption, and height and weight were collected by questionnaire and physical examination to investigate the epidemiological characteristics of the study subjects, and unconditional dichotomous logistic regression analysis was used to identify factors affecting the reduction of blood pressure among the hypertensive migratory bird population before and after taking medication in Hainan. Results　A total of 180 study subjects were included, including 77 (42.8%) males and 103 (57.2%) females, with 78 (43.3%) subjects aged ≤65. The hypertension levels were: 87 (48.3%) had normal high blood pressure, 56 (31.1%) had grade 1 hypertension and 37 (20.6%) had grade 2 hypertension. The higher the blood pressure classification, the lower the percentage of migratory individuals whose blood pressure dropped during their stay in Hainan. Age, hypertension classification, dietary habits, living environment, body mass index (BMI), and alcohol consumption were associated with a decrease in blood pressure during Hainan among the study participants who took hypertension medication regularly. Salty diet (OR=2.778, 95%CI:1.070-7.213, P=0.036) and alcohol consumption (OR=2.686, 95%CI:1.042-6.925, P=0.041) were unfavorable factors for lower diastolic blood pressure before taking medication; overweight (OR=3.487, 95%CI:1.306-9.310, P=0.013) was an unfavorable factor in the reduction of diastolic blood pressure after taking medication. Conclusion　The blood pressure reduction is more significant in migratory individuals in migratory individuals under 65 years old, with a light diet, no alcohol consumption and normal BMI. Environmental factors, age, dietary habits and lifestyle are the main causes of blood pressure, which can provide a reference basis for the health management of the migratory birds with hypertension in Hainan.

Objective:To explore the influencing factors of postoperative recurrence in patients with complex anal fistula, and to construct a nomogram model to predict the risk of postoperative recurrence and verify it.Methods:Clinical data of 310 patients with complex anal fistula who underwent fistulectomy in the hospital from Aug. 2019 to Mar. 2023 were retrospectively selected and divided into modeling group (93 cases) and validation group (217 cases) in a 3∶7 ratio according to system randomization method. Hospital electronic medical record system was used to collect patient baseline data and calculate the recurrence rate of patients 6 months after surgery. According to the data of the modeling group, multivariate Logistic regression was used to analyze the influencing factors of postoperative recurrence in patients with complex anal fistula. Based on the influencing factors, a nomogram model was established to predict the risk of postoperative recurrence, and external verification was performed based on the data of the validation group.Results:The recurrence rate at 6 months after operation was 20.43% (19/93) in the modeling group and 17.51% (38/217) in the validation group. There was no significant difference in recurrence rate between the two groups ( χ2=0.370, P=0.543) . The proportion of male, smoking history, diabetes mellitus, high anal fistula and unclear position of internal orifice in the recurrence group was higher than that in the non-recurrence group, and the body mass index and course of disease were higher than those in the non-recurrence group ( P<0.05) . Based on the above seven influencing factors, a nomogram model of the risk of recurrence of complex anal fistula after surgery was established. C index of the modeling group and the validation group was 0.984 and 0.798 respectively, the calibration curve was close to the ideal curve, and the Receiver operating characteristic AUC of the nomogram prediction model was>0.70, indicating that model consistency, prediction efficiency and differentiation were good. Conclusion:The nomogram prediction model based on gender, body mass index, smoking history, diabetes mellitus, course of disease, high anal fistula and internal orifice position can effectively predict the risk of postoperative recurrence in patients with complex anal fistula.

Abstract Socioeconomic status is an important factor affecting all-cause mortality. Income, education and occupation alone or in combination have been employed as a measure of socioeconomic status; however, the study results vary in measures. Material mechanism, lifestyle mechanism, psychological mechanism and community neighborhood mechanism have been accepted as the main intermediate mechanisms for the impact of socioeconomic status on all-cause mortality; however, the contribution of these mechanisms remains controversial. Based on the international and national publications pertaining to the association between socioeconomic status and all-cause mortality from 2012 to 2021, this review summarizes the relationship between socioeconomic status and all-cause mortality in different metrics and the intermediate mechanism of the impact of socioeconomic status on all-cause mortality, so as to provide insights for further studies.
