Gynecological cancer significantly affect the health of women.This review aimed to describe the global patterns and trends in the survival of patients with gynecological cancers.We searched PubMed,Embase,Web of Science,SinoMed,and SEER for survival analyses of cancer registration data of cervical,endometrial,and ovarian cancers published between 1980 and 2022.Globally,the highest 5-year observed survival rate for cervical cancer was 76.5%in Anshan,Liaoning,China(2008-2017).The 5-year observed survival rates of endometrial and ovarian cancers were higher in Finland(1995-1999,82.5%)and Singapore(1988-1992,62.0%).The 5-year relative survival rate of cervical cancer patients was higher in Haining,Zhejiang,China(2011-2014,85.8%).Korea ranked first at 89.0%and 64.5%for endometrial and ovarian cancers,respectively.Survival rates have improved for cervical,endometrial,and ovarian cancers.Patients aged≥75 years and those with advanced-stage disease had the worst 5-year survival rates.Survival rates were better for squamous cell carcinoma in cervical cancer,for endometrial carcinoma and mucinous adenocarcinoma in endometrial cancer,and for germ cell and sex-cord stromal tumors in ovarian cancer.Over the past four decades,the survival rates of gynecological cancers have increased globally,with notable increases in cervical and endometrial cancers.Survival rates are higher in developed countries,with a slow-growing trend.Future studies should focus on improving survival,especially in ovarian cancer patients.

AIM:To investigate the anti-fibrotic effect of Panax notoginseng saponins(PNS)in arecoline(ANE)-induced oral submucous fibrosis,and to analyze the effect of PNS on nuclear factor E2-related factor 2(Nrf2)/glu-tamate-cysteine ligase catalytic subunit(GCLC)signaling pathway.METHODS:CCK-8 assay was used to evaluate the effects of different concentrations of PNS and arecoline on the survival rate of human immortalized keratinocyte cell line Ha-CaT.The results of CCK-8 were used to select 75 mg/L arecoline,and 25,50 and 100 mg/L PNS as subsequent experi-mental concentrations.The cells were set as blank control group,model group,and low,medium and high doses(25,50 and 100 mg/L)of PNS groups.The protein and mRNA expressions of collagen type I(COL-I),E-cadherin,Nrf2,GCLC and glutathione reductase(GR)in each group were detected by Western blot and RT-qPCR.Immunofluorescence method was used to detect the entry of Nrf2 into the nucleus.Biochemical kits were used to detect the content of glutathione(GSH),nicotinamide adenine dinucleotide phosphate(NADPH)and malondialdehyde(MDA),and superoxide dis-mutase(SOD)activity in each group of cells.DCFH-DA fluorescent probe was used to detect the content of intracellular reactive oxygen species(ROS).RESULTS:Compared with the blank control group,the protein and mRNA expression of COL-I in the model group was up-regulated,and the protein and mRNA levels of E-cadherin,Nrf2,GCLC,nuclear Nrf2 and GR were down-regulated.The content of NADPH,MDA and ROS in the cells increased,and the content of GSH and the activity of SOD was significantly reduced.Compared with the model group,the protein and mRNA expression of COL-I was down-regulated,and the protein and mRNA expression of E-cadherin,Nrf2,GCLC,nuclear Nrf2 and GR were up-regulated in PNS 50 and 100 mg/L groups.Compared with the model group,the content of NADPH,MDA and ROS in cells decreased,and the content of GSH and the activity of SOD was significantly enhanced(P<0.05 or P<0.01).CON-CLUSION:Panax notoginseng saponins have anti-fibrosis effects in HaCaT cells,and their mechanism may be related to the activation of Nrf2/GCLC signaling pathway,thereby resisting oxidative stress and improving oral submucosal fibrosis.

OBJECTIVE: To verrify the anti-tumor efficacy and toxicity between juglone (Jug) and Jug-loaded PLGA nanoparticles (Jug-PLGA-NPs). METHODS: Jug-PLGA-NPs were prepared by ultrasonic emulsification. The anti-tumor activity of Jug (2, 3, 4 µg/mL) and Jug-PLGA-NPs (Jug: 2, 3, 4 µg/mL) in vitro was measured by MTT assay and cell apoptosis analysis. The distribution, anti-tumor effect and biological safety in vivo was evaluated on A375 nude mice. RESULTS: With the advantage of good penetration and targeting properties, Jug-PLGA-NPs significantly inhibited proliferation and migration of melanoma cells both in vitro and in vivo (P<0.05 or P<0.01) with acceptable biocompatibility. CONCLUSIONS Jug can inhibit the growth of melanoma but is highly toxic. With the advantage of sustained release, tumor targeting, anti-tumor activity and acceptable biological safety, Jug-PLGA-NPs provide a new pharmaceutical form for future application of Jug.

Aim To study the protective effect of fluoxetine hydrochloride on brain tissues of rats with simulated high altitude cerebral edema(HACE)and its mechanism.Methods The optimal dosage and time of fluoxetine hydrochloride were determined by the hypoxia tolerance test of mice under normal pressure.The rat model of brain edema at high altitude was established by large-scale low-pressure oxygen chamber.HE staining was used to observe the pathological changes of brain tissues in rats.Microplate reader was used to detect the corresponding indexes of oxidative stress such as malondialdehyde(MDA)level and superoxide dismutase(SOD)activity.The expressions of hypoxia-related proteins HIF-1α,VEGF,MMP-9,AQP4 and SERT were detected by Western blot.Results Compared with the hypoxia model group,after the intervention of fluoxetine hydrochloride,the survival time of mice was prolonged,and the middle dose of fluoxetine(14 mg·kg-1)had the best effect,with an extension rate of 17.78%.The pathological damage of brain was improved,the water content of brain decreased,and the permeability of blood-brain barrier decreased.MDA content in rat brain decreased and SOD activity increased.Western blot results showed that HIF-1α,VEGF,MMP-9,AQP4,SERT protein were significantly down-regulated.Conclusions Fluoxetine has protective effect on rats with brain edema at high altitude,and its mechanism may be related to improving oxidative stress,activating HIF-1α/VEGF/MMP-9 signaling pathway and affecting the expression of SERT protein.SERT may be a potential target for treating brain edema at high altitude.

Biotransformation of α-asarone by Alternaria longipes CGMCC 3.2875 yielded two pairs of new neolignans, (+) (7S, 8S, 7'S, 8'R) iso-magnosalicin (1a)/(-) (7R, 8R, 7'R, 8'S) iso-magnosalicin (1b) and (+) (7R, 8R, 7'S, 8'R) magnosalicin (2a)/(-) (7S, 8S, 7'R, 8'S) magnosalicin (2b), and four known metabolites, (±) acoraminol A (3), (±) acoraminol B (4), asaraldehyde (5), and 2, 4, 5-trimethoxybenzoic acid (6).

Objective:To study the risk factors of salivary occult blood in Tianjin public security police, and to explore feasible oral preventive and health care measures for police officers.Methods:The public security officers from all districts and counties of Tianjin who had physical examinations at the Health Examination Center of Tianjin Public Security Hospital from March 2012 to November 2012 were selected as the research objects. A stratified cluster random sampling method was used to draw samples of 388 cases. The salivary occult blood test paper was used to detect salivary occult blood. Then the self-designed "Tianjin public security police periodontal health questionnaire" was used to collect the relevant data of the subjects, and univariate analysis and multivariate unconditional Logistic regression analysis were carried out.Results:The univariate analysis result showed that salivary occult blood was significant correlated with age, police species, history of gingival bleeding, history of halitosis, history of alcohol consumption, family history and soft food preference (all P<0.005), but it was not correlated with education level, a regular oral examination, times of brushing teeth every day, time of brushing teeth every time, smoking history, hard food preference, sweet tooth preference and carbonated drinks preference(all P>0.05). Multivariate unconditional Logistic regression analysis result showed that criminal police, age, history of gingival bleeding, halitosis, smoking history were risk factors for periodontal disease, and brushing time of 2~3 minutes was protective factor for periodontal disease. Conclusions:The public security police lack the knowledge of oral health care and have not formed good daily oral health habits. Medical workers should carry out targeted oral health education to improve the awareness of the prevention and treatment of periodontal disease.

To explore the mechanism of Sijunzi Decoction in the treatment of ulcerative colitis(UC) based on network pharmacology. The active components and corresponding targets of Sijunzi Decoction were extracted with Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), and the targets were standardized with the help of Uniprot database. The related targets of UC were obtained through GeneCards database and Disgenet database, and the intersection targets of drugs and diseases were screened by R language. The visual regulation network of "active ingredient-disease target" of Sijunzi Decoction was constructed by Cytoscape software, and the protein-protein interaction network was constructed by STRING database. The functional enrichment analysis of gene ontology(GO) and the enrichment analysis of Kyoto encyclopedia of genes and genomes(KEGG) pathway were carried out on Bioconductor platform, and some of the targets were verified by animal experiments. Through database analysis, a total of 135 active components of Sijunzi Decoction, 114 predicted targets and 80 common targets with UC were obtained. The core target proteins included interleukin 6(IL-6), caspase-3(CASP3), vascular endothelial growth factor A(VEGFA), epidermal growth factor receptor(EGFR) and so on. GO functional enrichment analysis involved 102 items, which mainly affected transcription factor activity, enzyme activity, receptor activity and biochemical process regulation. KEGG pathway enrichment analysis showed that 120 items were involved in human cytomegalovirus infection, cancer, apoptosis, inflammation and other pathways. Mouse experiments showed that Sijunzi Decoction could down-regulate the expression of target proteins IL-6 and caspase-3 and inhibit intestinal epithelial cell apoptosis. The treatment of UC with Sijunzi Decoction is the result of the interaction among multi-components, multi-targets and multi-pathways. It is proved by experiments that Sijunzi Decoction may play an effective role by regulating the expression of IL-6 and caspase-3, and getting involved in apoptosis, inflammation and other pathways.

OBJECTIVE: To investigate the expression of miR-101 and EZH2 in patients with mantle cell lymphoma(MCL) and to analyze its correlation with clinical prognosis of MCL patients. METHODS: RQ-PCR and S-P immunohistochemistry were used to detect the expressions of miR-101 and EZH2 in tissue of MCL patients. CCK-8 was used to assay the effect of miR-100 minics on the proliferation of Jeko-1 and Mino cells; the flow cytometry with Annexin V/PI double staining was used to assay the apoptosis; Western blot was used to assay the effect of miR-101 minics on the expression of EZH2 protein in Jeko-1 and Mino cells. RESULTS: Compared with control group, miR-101 lowly expressed, and EZH2 protein highly expressed in MCL group, with very statistically significant difference(P<0.01).There was negative correlation between miR-101 and EZH2 expression(r=-0.638，P<0.05). The expression of miR-101 and EZH2 significantly correlated with B symptoms, International Prognostic Index(IPI) and Ann Arbor stage, respectively. Survival analysis showed that the overall survival(OS) rate of patients with low expression of miR-101 were significantly lower than that of patients with high miR-101 expression (P=0.0014), the OS rate of patients with EZH2 high expression were significantly lower than that of patients with EZH2 low expression (P=0.0093). The miR-100 minics could inhibit the proliferation of Jeko-1 and Mino cells, and increase the apoptotic rate. The expression of EZH2 protein was markedly suppressed by the miR-100 minics. CONCLUSION The expression of miR-101 and EZH2 is different in MCL patients with different clinical stage and prognosis. The miR-101 can inhibit the cell proliferation and induce cell apoptosis of mantle cell lymphoma by targeting EZH2.
