Objective:To explore the correlation between intrahepatic cholestasis of pregnancy(ICP)and ad-verse pregnancy outcomes.Methods:A total of 511 singleton pregnant women with ICP treated at The Third Affili-ated Hospital of Guangzhou Medical University from August 2017 to January 2024 were selected as the study sub-jects.Among them,patients were divided into the adverse pregnancy outcome group(n=49)and the control group without adverse pregnancy outcomes(n=462).The general and clinical data of the two groups were com-pared and analyzed.Results:①General situation:The number of pregnancies and deliveries,ICU transfer rate,total hospital stay,and total hospitalization costs were significantly higher in the adverse pregnancy outcome group compared to the control group(P<0.05).The number of prenatal check-ups,diagnostic gestational weeks,and gestational weeks at delivery were significantly lower compared to the control group(P<0.05).②Clinical symp-toms:The incidence of itching in the adverse pregnancy outcome group was lower compared to the control group(10.2%vs.26.6%,P<0.05),while other symptoms such as rash,fatigue,jaundice,and gastrointestinal symp-toms showed no significant difference between the two groups(P>0.05).③Laboratory examinations:Compared with the control group,patients in the adverse pregnancy outcome group had significantly the increased levels of alanine aminotransferase,aspartate aminotransferase,uric acid,urea nitrogen,and triglycerides,and significantly the decreased levels of alkaline phosphatase and fasting blood glucose,with statistical significance(P<0.05).Other biochemical indicators showed no significant difference between the two groups(P>0.05).④ICP grading and complications:The proportion of early-onset ICP,severe and very severe ICP in the adverse pregnancy out-come group was significantly higher compared to the control group(P<0.001);the proportion of adverse preg-nancy outcome group with pregnancy-induced hypertension was significantly higher compared to the control group;the incidence of preterm birth,fetal growth restriction,meconium-stained amniotic fluid,and fetal distress in the adverse pregnancy outcome group was significantly higher compared to the control group(P<0.001).⑤Neo-natal outcomes:The neonatal Apgar scores(1 min,5 min,10 min)and neonatal weight in the adverse pregnancy outcome group were lower compared to the control group(P<0.001),and the incidence of mild neonatal asphyx-ia was significantly higher,with a statistically significant difference(P<0.001).Conclusions:The severity of ICP is closely related to the occurrence of adverse pregnancy outcomes.Therefore,it is clinically necessary to pay at-tention to the grading of ICP,closely monitor the levels of total bile acids and liver enzymes,and try to avoid ad-verse pregnancy outcomes,especially intrauterine fetal death.

Objective:To conduct a Meta-synthesis on the characteristics of symptom help-seeking behavior in adult cancer patients, so as to provide evidence-based guidance for early intervention of symptom help-seeking behavior in cancer patients in China.Methods:Qualitative studies on symptom help-seeking behavioral characteristics of cancer patients were systematically searched in PubMed, Cochrane Library, Web of Science, ProQuest, Nature, ScienceDirect, China National Knowledge Infrastructure, WanFang Data, China Biology Medicine disc, and VIP. The search period was from database establishment to December 31, 2024. Included literature was independently evaluated using the Australian Joanna Briggs Institute Center for Evidence-Based Health Care Quality Assessment Criteria for Qualitative Research. The results were integrated through the Meta-synthesis method.Results:A total of 15 papers were included, and 30 findings were distilled and grouped into nine categories, resulting in three integrated findings of low symptom perception and interpretation bias, coping styles of symptom disclosure, and factors influencing symptom help-seeking behaviors.Conclusions:Symptom help-seeking behaviors of cancer patients are influenced by a variety of factors, and understanding their behavioral characteristics is useful in informing the development of intervention strategies.

Objective: To investigate the inhibitory effect of curcumin(Cur) on IL-1β-induced cartilage damage and to study the relationship between the regulatory mechanisms of the DUSP1/p38 MAPK signalling pathway in the above process. Methods: Chondrocytes(C28/I2) and postoperative primary chondrocytes from osteoarthritis patients were divided into control and experimental groups, and the experimental group was treated with different concentrations of Cur(0, 10, 20, 40, 60, 80 μmol/L) after applying the inflammatory induction treatment with IL-1β(10 μg/L). The cell proliferation inhibition rate was determined by cell viability assay(CCK-8), the apoptosis rate was detected by flow cytometry assay. Real-time fluorescence quantitative PCR(qRT-PCR), Western blot, and immunofluorescence assay were used to detect type II collagen α1 chain(Collagen Ⅱ), matrix metallopeptidase 13(MMP13), interleukin-1β(IL-1β), BCL2-related X protein(Bax), B lymphocytoma-2(Bcl-2), dual-specificity phosphatase 1(DUSP1), p38 mitogen-activated protein kinase(p38), and phosphorylated p38 mitogen-activated protein kinase(p-p38) RNA and protein expression levels. The role of the DUSP1/p38 MAPK axis in the inhibition of chondrocyte oxidative stress, apoptosis and inflammation by Cur was further validated using DUSP1 interfering RNA and p38 MAPK pathway inhibitor(SB). Results: Cur significantly inhibited the IL-1β-induced decrease in chondrocyte viability and significantly reduced the levels of oxidative stress, apoptosis, and inflammation in chondrocytes; Cur inhibited the expression of MMP13, IL-1β, Bax, and p-p38 proteins, while the expression of Collagen II, Bcl-2, and DUSP1 proteins significantly increased; IL-1β and interfering RNA silencing DUSP1 activated the p38 pathway, while Cur inhibited the activation of the p38 pathway; the use of p38 MAPK pathway inhibitors reduced cellular inflammation. Conclusion Cur attenuates IL-1β-induced oxidative stress, apoptosis and inflammation in chondrocytes by promoting the expression of DUSP1 protein and inhibiting the activation of p38 MAPK pathway.

Objective To investigate the regulatory effect of small interfering RNA(siRNA)silencing zinc finger protein A20 on pyroptosis of rheumatoid arthritis(RA)fibroblast-like synoviocytes(HFLS-RA).Methods Hu-man FLS-RA cell line MH7A cells were cultivated,A20 siRNA silencing group was synthesized for knocking down the human A20 gene,and then specific A20 gene siRNA and siRNA-NC(negative control)were transfected into MH7A cells using liposome method.RT-qPCR was applied to detect the expression of NLRP3 and Caspase-1 mRNA in cells.The protein expression of NLRP3 and Caspase-1 was detected by Western blot,and IL-1β and IL-18 in cell culture medium were detected by ELISA method.Transmission electron microscopy(TEM)was used to detect pyroptosis.Results After A20 knockdown,the mRNA and expression of NLRP3 and Caspase-1 in MH7A cells in the siRNA-A20 group were significantly increased as compared with the siRNA-NC group(P＜0.01).The concentration of IL-1β and IL-18 in the cell culture supernatant of the siRNA-A20 group was sig-nificantly increased compared with the siRNA-NC group(P＜0.01).Compared with the siRNA-NC group,some cells in the siRNA-A20 group showed swollen and ruptured.The integrity of the cell membrane was also lost,and a large area of edema was present in the cell.In addition,a blurred depression of the local nuclear membrane was noted,while an increase in heterochromatin pyknosis was accompanied by their uneven distribution as well as their aggregation around the nuclear membrane.Conclusions Silencing of A20 gene with siRNA might promote NLRP3/Caspase-1 mediated pyroptosis in HFLS-RA,which lays an experimental foundation for new clinical treatment meth-ods of RA.

Objective To explore the correlation between coronary fat attenuation index of perivascular adipose tissue(FAIPVAT),as well as volumetric perivascular characterization index(VPCI),and coronary heart disease(CHD).Methods A total of 112 patients who underwent coronary computed tomography angiography(CCTA)and coronary angiography(CAG)examinations within 2 weeks were selected.The patients were divided into CHD group and control group according to the degree of coronary artery stenosis,and were divided into calcified plaque group,non-calcified plaque group and mixed plaque group according to the nature of plaque.The correlation between FAIPVAT,VPCI and CHD were evaluated.Results Of the 112 patients,71 patients in the CHD group and 41 patients in the control group.There were significant differences in gender,age,FAIPVAT and VPCI between the two groups.FAIPVAT and VPCI were positively correlated with CHD(r=0.445,P＜0.01;r=0.669,P＜0.01).FAIPVAT and VPCI were analyzed by receiver operating characteristic(ROC)curve,the area under the curve(AUC)of FAIPVAT was 0.770,the cut-off value was-81.659 HU,the sensitiv-ity was 0.592,and the specificity was 0.878,while the AUC of VPCI was 0.892,the cut-off value was 8.056,the sensitivity was 0.887,and the specificity was 0.805.There were significant differences in FAIPVAT and VPCI between non-calcified plaque group and calci-fied plaque group.FAIPVAT and VPCI of mixed plaque group and calcified plaque group were significantly different.Conclusion FAIPVAT and VPCI have some certain correlation with CHD.FAIPVAT and VPCI can accurately evaluate the risk level of CHD and coronary artery inflammation,and the value of individualized VPCI is higher.
