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

Objective:To investigate the impact of excessive fluoride exposure on the expression profile of microRNA (miRNA) in mouse testes, and elucidate the reproductive toxicity mechanism of fluoride.Methods:A total of 24 8-week-old C57BL/6J male mice weighing (23 ± 1) g were randomly divided into a control group [0 mg/L sodium fluoride (NaF)] and a fluoride exposure group (50 mg/L NaF) using a random number table method, with 12 mice in each group. After 90 days of treatment, the mice were anesthetized and euthanized. Sperm samples were collected to assess their quantity, viability, and deformity rate. Additionally, testicular tissue was stained with hematoxylin-eosin (HE). RNA was extracted from testicular tissue, and high-throughput sequencing technology was employed to analyze the effect of fluoride on the expression profile of mouse testicular miRNA. Deferentially expressed miRNA was screened and its target genes were predicted, and functional annotation and pathway enrichment analysis were performed. Real-time fluorescence quantitative PCR (qRT-PCR) was used to verify the expression level of deferentially expressed miRNA.Results:Compared with the control group [number of sperm: (11.30 ± 2.52) × 10 6/ml; viability rate: (90.07 ± 4.34)%; deformity rate: (15.49 ± 3.25)%], the number of sperm of mice exposed to fluoride [(9.01 ± 2.25) × 10 6/ml] and the viability rate [(84.34 ± 4.21)%] decreased ( P = 0.041, 0.003), while deformity rate [(22.36 ± 6.51)%] increased ( P = 0.003). Furthermore, in the fluoride exposure group, the interstitial distance of testis increased, the number of sperm in the spermatogenic tubule decreased, and the cell arrangement was disordered. Through sequencing, 34 deferentially expressed miRNAs were identified in the testes of mice exposed to fluoride. According to qRT-PCR verification, compared with the control group, the expression levels of mmu-miR-29b-1-5p ( P < 0.001), mmu-miR-196a-5p ( P = 0.002), and mmu-miR-196b-5p ( P = 0.031) in the testes of mice exposed to fluoride were significantly increased, and the expression levels of mmu-let-7a-2-3p ( P < 0.001) and mmu-miR-466n-3p ( P = 0.018) were significantly decreased, consistent with the sequencing results. By KEGG enrichment of deferentially expressed miRNA target genes, it was found that fluoride exposure could change the axon guidance signal pathway, olfactory transduction pathway, neuroactive ligand-receptor interaction pathway, and lysosome signal pathway, etc., in mouse testes. Conclusions:Fluoride exposure may induce testicular injury by altering the expression profile of miRNA in the testes and by mediating the post-transcriptional regulatory signal pathway. Testicular miRNA may be a potential biomarker of fluoride reproductive toxicity, which may provide a new idea and perspective for exploring the mechanism of fluoride poisoning.

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

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

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.

ABSTRACT

Hyperuricemia is a chronic disease caused by the imbalance of uric acid synthesis and excretion, which is influenced by both environmental and genetic factors. The results of genome-wide association analysis related to hyperuricemia in different regions during the past decade have shown that genes related to hyperuricemia may be region- specific. This article summarizes the genes detected by GWAS, and describes some of the involved molecular mechanisms. The genes related to hyperuricemia shared by people in Europe, Asia, Africa and South America, and genes related to hyperuricemia unique to Asian populations are reviewed in this article. In addition, some of the genes’ functions are discussed to enhance the understanding of the pathogenesis of hyperuricemia.

ABSTRACT

Objective@#To analyze the variations of procalcitionin (PCT) and red blood cell distribution width (RDW) in premature infants with septicemia and to investigate their values in evaluating the severity and prognosis of septicemia.@*Methods@#A retrospective study was conducted to analyze the medical records of 96 premature infants diagnosed with septicemia and admitted to the First Affiliated Hospital of Anhui Medical University from December 1, 2014 to December 1, 2018. According to the severity of the disease and neonatal shock score, there were 42 cases selected to the severe septicemia group (severe clinical condition with shock, shock score >6 points) and 54 in the mild septicemia group (mild clinical condition without shock or shock score ≤6 points). Moreover, after three days' treatment, they were divided into two groups: death group (n=10) and survival group (n=86, survived during hospitalization). Peripheral venous blood samples were collected before and on the first and third day after treatment to detect PCT and RDW. Dynamic changes of the two indexes were compared between different groups. Mann-Whitney U test, Wilcoxon rank sum test, Friedman test or receiver operating characteristic (ROC) curve was used for statistical analysis.@*Results@#(1) Before and on the first and third day after treatment, the severe septicemia group had a higher level of PCT than the mild group [3.7 (0.4-37.3) vs 1.4 (0.2-5.0) ng/ml, 43.1 (18.7-83.0) vs 17.1 (4.1-34.6) ng/ml, 26.1 (3.8-67.3) vs 4.8 (0.3-32.9) ng/ml; Z=-2.017, -3.350 and -2.932; all P<0.05]. In both groups, PCT level on the first day after treatment was the highest, and that on the third day after treatment was higher than that before treatment (all P<0.05). On the first and third day after treatment, RDW in the severe group was higher than that in the mild group [16.5% (16.2%-18.6%) vs 16.3% (15.5%-17.3%), 16.1% (15.5%-19.4%) vs 15.7% (15.1%-16.5%); Z=-1.992 and -2.165; both P<0.05]. In the severe and mild groups, RDW on the first day after treatment was higher than that before and on the third day after treatment; in the mild group, RDW on the third day after treatment was lower than that before treatment, while in the severe group, RDW on the third day after treatment was higher than that before treatment (all P<0.05). (2) On the first and third day after treatment, PCT and RDW in the death group were higher than those in the survival group [PCT: 162.0 (62.9-187.2) vs 19.9 (4.3-46.1) ng/ml, 122.6 (65.0-180.8) vs 6.2 (0.5-32.9) ng/ml; Z=-4.114 and -4.594; RDW: 18.4% (16.9%-21.2%) vs 16.3% (15.7%-17.2%), 21.8% (20.6%-22.2%) vs 15.8% (15.2%-16.5%); Z=-3.307 and -4.831; all P<0.05]. In both groups, PCT on the first day after treatment was higher than that before and on the third day after treatment, and the level on the third day after treatment was higher than that before treatment (all P<0.05). In the death group, RDW on the first and third day after treatment were higher than that before treatment, and RDW on the third day after treatment was higher than that on the first day; in the survival group, RDW on the first day after treatment was higher than that before treatment, but on the third day after treatment, it was lower than that before and on the first day after treatment (all P<0.05). (3) The cut-off values of PCT for predicting severe septicemia in premature infants before and on the first and third day after treatment were 3.475, 29.765 and 3.460 ng/ml, respectively, and the sensitivity and specificity were 54.8% and 75.9%, 69.0% and 72.2%, and 83.3% and 46.3%, respectively. The cut-off values of PCT for predicting the death of premature infants with septicemia on the first and third day after treatment were 40.595 and 64.855 ng/ml, respectively, with the specificity of 73.3% and 87.2% and sensitivity of both 100.0%. The predictive thresholds of RDW for severe septicemia on the first and third day after treatment were 15.650% and 18.300%, respectively, and the sensitivity and specificity were 95.2% and 29.6%, 33.3% and 92.6%, respectively. The predictive thresholds for death were 16.650% and 18.450%, and the sensitivity and specificity were 100.0% and 68.6%, 100.0% and 91.9%, respectively.@*Conclusions@#Dynamic monitoring of PCT and RDW levels may help with early diagnosis, determination of severity and prognosis prediction of severe septicemia in premature infants.
