ABSTRACT

Globally, gynecological malignancies are common types of female cancer and the main cause of cancer death among women. Cervical cancer, endometrial cancer and ovarian cancer, which are the main types of gynecological cancers, pose a significant threat to women's health worldwide. Studies have shown that diet plays an important role in the occurrence and development of gynecological cancers such as cervical cancer, endometrial cancer, and ovarian cancer, for which added sugar may be an influencing factor due to its food source characteristic and related biological effect. However, this paper reviewed the research progress on the relationship between consumption of added sugar and gynecological cancers such as endometrial cancer, ovarian cancer and cervical cancer, with a view to providing a reference for the active prevention of gynecological cancer.

ABSTRACT

Myeloid-derived suppressor cells (MDSCs) are a group of immature and heterogeneous cells that can inhibit T cell function. In pathological conditions such as tumors, infections, and chronic inflammation, the large expansion of MDSCs is involved in processes of immune escape, immune tolerance and inflammatory reactions. MDSCs are also crucial in the pathophysiology of hepatitis B virus (HBV) infection, however, their activation, differentiation, and function during HBV infection are still unclear. This article reviews the general characteristics and roles of MDSCs in HBV infection, as well as related drug therapies, in order to provide information for further research on the related mechanism and potential targeted treatment.

ABSTRACT

Objective:To investigate the correlation between serum N-terminal pro-brain natriuretic peptide (NT-pro-BNP) and lipoprotein phospholipase A2 (Lp-PLA2) levels and the severity of coronary artery lesions in patients with acute coronary syndrome (ACS) complicated with type 2 diabetes mellitus (T2DM) .Methods:A total of 68 patients with ACS and T2DM who were admitted to our hospital from Jun. 2018 to Oct. 2020 were selected as the experimental group, and the control group was 52 patients with simple ACS. The serum NT-pro-BNP and Lp-PLA2 levels of the two groups of patients were detected, and the correlation between the serum NT-pro-BNP and Lp-PLA2 levels and the degree of coronary artery disease in patients with ACS complicated with T2DM was analyzed to screen for ACS complicated with T2DM. Influencing factors of moderate to severe coronary artery disease in diabetic patients were selected.Results:The serum levels of NT-pro-BNP[ (349.18±45.98 vs 235.68±26.37) ] ng/L and Lp-PLA2 [ (421.84±55.84 vs 318.62±36.69) ] ng/mL in the experimental group were higher than those in the control group ( P<0.05) . The levels of serum NT-pro-BNP [ (374.35±39.42 vs 320.88±35.41) ] ng/L and Lp-PLA2 [ (452.67±48.32 vs 387.16±40.45) ]ng/mL in the moderate-severe group were higher than those in the mild group ( P<0.05) . Serum NT-pro-BNP and Lp-PLA2 levels were positively correlated with the severity of coronary artery lesions in patients with ACS and T2DM ( r=-0.585, P=0.000; r=-0.595, P=0.000) . Serum NT-pro-BNP and Lp-PLA2 were risk factors for moderate to severe coronary artery disease in patients with ACS complicated with T2DM ( P<0.05) . Conclusion:Serum levels of NT-pro-BNP and Lp-PLA2 in patients with ACS complicated with type 2 diabetes mellitus are related to the degree of coronary artery disease.

ABSTRACT

The human biorhythm is closely related to the blood pressure level and the effect of the antihypertensive treatment of hypertension. The human circadian biorhythm changes the therapeutic effect of antihypertensive drugs by affecting the pharmacokinetics and pharmacodynamics; at the same time, following the human blood pressure rhythm in the treatment of hypertension can reduce the risk of target organ damage and cardiovascular and cerebrovascular events. Therefore, in the treatment of hypertension, the administration time and drug dosage should be adjusted according to the pharmacochronology to obtain the best curative effect and minimal side effects, and reduce the occurrence of adverse reactions and complications.

ABSTRACT

Associations between ambient particulate matter exposure and platelet counts are inconsistent in previous studies, and study on the effect of long-term exposure especially in Asian populations is limited. We explored the associations between long-term PM2.5 (particulate matter < 2.5 µm) exposure and platelet counts using a prospective cohort study in Northeast China. We used a logistic regression model to analyze the effects of different PM2.5 increments and platelet count elevation. Mixed linear models were used to analyze the association between PM2.5 concentration and platelet counts. Interaction and sub-group analyses were also conducted. Results showed that every 1 µg/m3 increment of PM2.5 exposure was associated with 0.29% (95%CI: 0.25-0.32%) increase in platelet counts and 10% (95%CI: 8-12%) higher risk of platelet elevation. Effects of long-term PM2.5 exposure on platelet elevation were stronger in male participants, of Han ethnicity, and without diabetes. Long-term PM2.5 exposure would increase platelet counts in adults in Northeast area of China, which might add more evidence to the potential biological mechanisms responsible for the effect of air pollution exposure on cardiovascular disease.

ABSTRACT

The prevalence of gestational diabetes mellitus (GDM) has been increasing worldwide. Dietary patterns and air pollution are closely related to the occurrence of GDM. No previous study has explored the interaction effect of air pollution exposure and dietary patterns on GDM. We explored the interaction effect between main dietary patterns and pre-pregnancy exposure to air pollution on the development of GDM based on a prospective birth cohort in Northeast China. A total of 2244 participants were included in this study. Factor analysis was used to identify dietary patterns. We found that long-term exposure to nitrogen dioxide (NO2) and carbon monoxide (CO) before pregnancy was significantly associated with an increased risk of GDM; the animal foods pattern significantly modified these associations. The sub-group analysis showed that compared with a lower intake in the animal foods pattern (NO2, odds ratio [OR] = 1.07, 95% confidence interval [CI]: 0.84, 1.35; CO, OR = 1.05, 95% CI: 0.81, 1.34), higher intake in the animal foods pattern (NO2, OR = 1.41, 95% CI: 1.09, 1.83; CO, OR = 1.36, 95% CI: 1.05, 1.76) before pregnancy increased the hazardous effects of NO2 and CO on GDM development. The intake of animal blood, animal organs, preserved eggs, and processed meat products in animal food pattern could all aggravate the effect of exposure to air pollution due to NO2 and CO on GDM. Our study demonstrated that there was a significant interaction effect between animal foods pattern and exposure to air pollution on GDM. These results provide further scientific evidence of the associations among air pollution, dietary intake, and GDM, and may help as well as the prevention of GDM.

ABSTRACT

In China, the aging of the population is becoming increasingly serious. Common diseases of the elderly, such as sarcopenia and metabolic syndrome, have gradually become key factors affecting their quality of life. Sarcopenia is a decline in skeletal muscle mass and function associated with aging. Metabolic diseases such as obesity, hypertension and diabetes play an important role in the development of sarcopenia. In recent years, the relationship between sarcopenia and metabolic syndrome has also become a research hotspot, but there is still a lack of strong evidence on whether they are a risk factor for each other. This paper summarizes the epidemiological data of the relationship between sarcopenia and metabolic syndrome in the last 5 years, and reviews the epidemiological background, research status and potential links in biological mechanism of sarcopenia and metabolic syndrome. There is a significant correlation between sarcopenia and metabolic syndrome that may share similar biological mechanisms. However, there are still some limitations in this study. In addition, the methods of early screening and diagnosis of sarcopenia should be continuously explored to achieve the purpose of simplicity, rapidity and efficiency. This review aims to raise the population's awareness of chronic syndromes sarcopenia and metabolic syndrome, and to provide theoretical support for further research on their relevance.

ABSTRACT

The incidence rate of ovarian cancer ranks the third among female malignant tumors, the mortality rate ranks the first and the prognosis is poor. Ovarian cancer poses a serious threat to the health of women's lives. The incidence of ovarian cancer is related to heredity, endocrine disorders and adverse lifestyle factors. In recent years, some scholars have carried out the impact of lifestyle, especially shift work, on the occurrence and development of ovarian cancer. Shift work can lead to circadian disruption, which affects hormonal balance in the body and may be a risk factor for ovarian cancer. This review summarizes four cohort studies and two case-control studies on the relation between shift work and ovarian cancer. The conclusion of the studies is inconsistent, suggesting that further researches are needed.
