Objective To explore the predicative value of transvaginal ultrasonography and 48 hours blood HCG ratio for ectopic pregnancy(EP).Methods A total of 90 patients in our hospital from June 2014 to May 2016 were selected as the object according to the pregnancy result and postoperative pathology (40 cases in EP group and 50 cases in control group).The endometrial thickness was measured through transvaginal ultrasonography while blood HCG was detected by chemiluminescence technique and 48 hours blood HCG ratio was calculated.To evaluate the individual and combined predicative value of endometrial thickness and 48 hours blood HCG ratio for EP,receiver operating characteristic curves(ROC) were generated and logistic regression analysis was conducted.Results The endometriam thickness and 48 h blood HCG ratio of EP group were (11.75 ± 3.42) mm and (1.06 ± 0.38) ％,respectively,which were lower than (15.52 ± 3.98) mm and (1.46 ± 0.20)％ of control group,the differences were statistically significant (P =0.000).The AUCs and their corresponding 95％ confidential intervals(CI) were 0.77[95％ CI(0.67,0.87)] and 0.82[95％ CI(0.73,0.91)],respectively.Combined ROC analysis based on the 2 indexes revealed an elevated AUC of 0.89 [95％ CI(0.83,0.95)],the differences were statistically significant(P =0.04).Conclusion The endometrial thickness and 48 hours blood HCG ratio can be acted as useful predicative biomarkers for detection of EP.A combination of the two indexes could be a useful predicative biomarker for future clinical trials with EP and may act as a suitable add-on biomarker to the panel of methods already existing for EP.

Background and purpose:Human epidermal growth factor receptor 2(HER2)serves as one of the paramount drivers of breast cancer metastasis,with roughly 20%-30%of breast cancer patients exhibiting high expression of HER2.The expression level of HER2 is regulatable at multiple molecular levels and determines the metastatic potential of breast cancer cells;however,the manner in which HER2 expression is modulated at the mRNA level remains ambiguous.Circ-0007766 is a circRNA originated from the coding gene ERBB2 for HER2,and whether circ-0007766 can regulate HER2 expression via the ceRNA mechanism has not been reported.This study aimed to analyze whether circ-0007766 acts as a miR-1972 sponge to promote breast cancer cell migration and invasion via upregulation of HER2 expression.Methods:In this study,a high-throughput circRNA chip was employed to screen for circRNAs that exhibited highly specific expression in HER2-positive breast cancer cells.RNA fluorescence in situ hybridization(FISH)was utilized to detect the subcellular localization of circ-0007766.The BaseScope experiment was conducted to analyze the expression level of circ-0007766 in breast cancer tissues and its clinical diagnostic significance.Breast cancer cell models with overexpression and knockdown of circ-0007766 were constructed by transfecting cloning plasmids and siRNA in vitro.The effect of circ-0007766 on the migration and invasion of breast cancer cells was assessed using transwell migration and invasion experiments,and the migration and invasion abilities of MDA-MB-231 and SK-BR-3 cells were measured.Additionally,it was evaluated whether circ-0007766 could promote the migration and invasion of breast cancer cells through miR-1972.A dual luciferase reporter gene assay was used to verify whether circ-0007766 could regulate HER2 expression by binding to miR-1972.The direct interaction between circ-0007766 and miR-1972 was further verified through the RAP experiment.RIP detection was performed in MDA-MB-231 cells,and the relative 3'UTR of HER2 mRNA was measured by real-time fluorescence quantitative polymerase chain reaction(RTFQ-PCR).Western blot was used to detect the protein expressions.Results:Circ-0007766 was conspicuously highly expressed in HER2-positive breast cancer cells and distributed in both the cytoplasm and nucleus of cells,with the preponderance being in the cytoplasm.The expression level of circ-0007766 was strikingly higher in breast cancer tissues than in para-cancerous tissues.The expression of circ-0007766 was significantly elevated in HER2-positive breast cancer samples compared with HER2-negative samples.The overexpression(knockdown)of circ-0007766 in HER2-negative breast cancer cells(in HER2-positive breast cancer cells)was capable of promoting(inhibiting)the migration and invasion of breast cancer cells.Circ-0007766 directly bound to miR-1972,which inhibited breast cancer cell migration and invasion,thereby forming an endogenous competitive RNA(ceRNA)regulatory network and impeding the downregulation of HER2 mRNA and protein expression mediated by miR-1972.Circ-0007766 could potentiate the inhibitory effect of miR-1972 on HER2-mediated breast cancer cell migration and invasion that was negatively regulated by miR-1972.CircRNAs sequestered miRNAs to function as ceRNAs,thereby regulating gene expression at both the transcriptional and translational levels.Finally,we discovered that the expressions of circ-0007766 and HER2 were positively correlated in breast cancer cell and tissue samples,while the expression levels of miR-1972 and HER2 were negatively correlated.Circ-0007766 could specifically target miR-1972 to hinder its regulatory effect on HER2 expression.Conclusion:This study discovers that circ-0007766 facilitates the migration and invasion of breast cancer cells via the miR-1972/HER2 signal axis,offering a novel biomarker and potential therapeutic target for patients with metastatic HER2-positive breast cancer.

Objective To investigate the clinical features and prognosis of hepatocellular carcinoma(HCC).Methods Medical records were collected from 850 HCC patients who were admitted to Hubei Provincial Hospital of Traditional Chinese Medicine from December 2014 to May 2022,and their clinical and prognostic features were analyzed.The chi-square test were used for comparison of categorical data between groups;the Kaplan-Meier method was used to calculate survival time and survival rate,and the log-rank test was used for comparison of survival time based on baseline features.Results Among the 850 HCC patients,male patients accounted for 82.6%,and the median age at initial diagnosis was 58.0(49.0,66.0)years,with the highest proportion of patients aged 50-69 years(59.8%).The patients with HBV infection accounted for the highest proportion of 77.4%;at initial diagnosis,49.2%of the patients had portal vein tumor thrombus,and 20.2%of the patients had extrahepatic metastasis,among which pulmonary metastasis accounted for the highest proportion of 44.2%(76/172).The patients with Barcelona Clinic Liver Cancer(BCLC)stage A(0),B,C,and D HCC accounted for 20.4%,22.5%,41.5%,and 15.6%,respectively.There was a significant difference in the distribution of BCLC stages between different groups based on sex(χ2=16.631,P=0.001),age(χ2=24.261,P=0.019),place of residence(χ2=39.776,P＜0.001),presence or absence of viral hepatitis(χ2=8.338,P=0.040),and presence or absence of regular antiviral therapy before initial diagnosis(χ2=26.140,P＜0.001).Follow-up was performed for 489 patients till death,with a median survival time of 19.99 months(95%confidence interval[CI]:14.86-25.12),and the 1-,3-,5-,and 10-year cumulative survival rates were 60.7%,39.9%,29.4%,and 22.7%,respectively.There was a significant difference in survival time between different groups based on age(χ2=13.452,P=0.009),history of viral hepatitis(χ2=6.123,P=0.013),regular antiviral therapy before initial diagnosis(χ2=15.505,P＜0.001),comorbidity with type 2 diabetes(χ2=9.820,P=0.002),the number of tumors(χ2=57.713,P＜0.001),maximum tumor diameter(χ2=41.862,P＜0.001),portal vein tumor thrombus(χ2=293.909,P＜0.001),extrahepatic metastasis at initial diagnosis(χ2=118.329,P＜0.001),BCLC stage(χ2=465.638,P＜0.001),surgical resection(χ2=78.86,P＜0.001),local treatment(χ2=36.216,P＜0.001),immune checkpoint inhibitor treatment and/or anti-tumor angiogenesis therapy(χ2=7.182,P=0.007),traditional Chinese medicine decoction treatment(χ2=30.050,P＜0.001),and comprehensive treatment regimens(χ2=13.221,P=0.004).Progression-free survival(PFS)was recorded for 259 patients(30.5%),with a median PFS of 10.98 months(95%CI:8.54-13.42).Conclusion HCC patients exhibit epidemiological characteristics in terms of sex,age,place of residence,presence or absence of viral hepatitis,regular antiviral therapy before initial diagnosis,tumor characteristics,treatment modality,and prognosis,with a low early detection rate and a short overall survival time,and therefore,it is urgent to perform early screening,early diagnosis,and early treatment.
