Objective To investigate the effect of the Shenghua Sanjia decoction on endometrial damage after induced abortion in rats by regulating the Fas/Fas ligand(FasL)signaling pathway.Methods Fifty pregnant rats were randomly assigned to five groups:normal con-trol,model,low-and high-dose Shenghua Sanjia decoction(12.6 g/kg and 25.2 g/kg,respectively),and dydrogesterone(3 mg/kg)groups,with 10 rats in each group.In all groups except the normal control group,rats were administered 16.6 mg/kg mifepristone combined with 100 μg/kg misoprostol to establish an artificial abortion model,and the endometrial injury model was established by a mechanical injury method.After administering the respective drug intervention,enzyme-linked immunosorbent assay(ELISA)was used to measure serum levels of estrogen(E2),progesterone(P),and prolactin(PRL).Histopathological changes of the endometrium were evaluated using HE staining.Masson staining was employed to assess endometrial fibrosis,whereas TdT-mediated dUTP nick-end labeling(TUNEL)was uti-lized to detect apoptosis in the endometrial tissue.Additionally,the mRNA expression levels of the estrogen receptor(ER),progesterone receptor(PR),prolactin receptor(PR LR),vascular endothelial growth factor(VEGF),Fas,and FasL in the endometrial tissue were measu-red using real-time quantitative PCR.Finally,Western blotting was performed to analyze the protein expression levels of transforming growth factor-β(TGF-β),matrix metalloproteinase-9(MMP-9),Fas,and FasL in the endometrial tissue.Results Compared to the normal control group,the model group showed a decreased E2,P,and PRL serum levels,a reduction in the mRNA expressions of ER,PR,PRLR,and VEGF as well as decreased protein expression of MMP-9 in the endometrial tissue.However,the apoptosis rate,mRNA expression of Fas and FasL,and protein expression of TGF-β,Fas,and FasL in the endometrial tissue were all increased(P＜0.05).Lastly,the endo-metrial tissue was found to be severely damaged with the collagen fibers increased.Compared to the model group,the low-and high-dose Shenghua Sanjia decoction and dydrogesterone groups showed an increase in the serum levels of E2,P,and PRL,as well as an elevation in the mRNA expression of ER,PR,PRLR,and VEGF;similarly the protein expression of MMP-9 in the endometrial tissue was increased.However,the apoptosis rate,mRNA expression of Fas and FasL,and protein expression of TGF-β,Fas,and FasL in the endometrial tissue were all decreased(P＜0.05).Conversely,the histopathological damage of the endometrium was found to be alleviated with the collagen fibers decreased.Conclusion The Shenghua Sanjia decoction can reduce endometrial fibrosis and apoptosis,while promoting endome-trial repair after the induction of abortion in rats.The underlying mechanism may be associated with the inhibition of the Fas/FasL signa-ling pathway activity.

Objective To investigate the computed tomography (CT) features of solitary nodular invasive mucinous lung adenocarcinoma (IMA) in stage IA and establish its prediction model. Methods We included 53 lesions of 53 patients with stage-IA IMA and 141 control lesions of 141 patients with invasive non-mucinous lung adenocarcinoma (NIMA) that were confirmed by surgical pathology in our hospital from January 2017 to December 2019. Univariable analysis was used to compare the demographics and CT signs of the two groups. Multivariable logistic regression analysis was performed to determine the main factors influencing solitary nodular IMA. A risk score prediction model was constructed based on the regression coefficients of the main influencing factors. A receiver operating characteristic (ROC) curve was used to assess the performance of the model. Results The univariable analysis showed significant differences between the two groups in age, largest nodule diameter, tumor-lung interface, lobulation, spiculation, air-bronchogram or vacuole sign, vessel abnormalities (P < 0.05). The spiculation sign was different between the two groups, which was longer and softer in the IMA group while shorter and harder in the NIMA group. There was no significant difference in sex, nodule shape, or pleural retraction (P > 0.05), but irregular shapes were slightly more frequent in the IMA group. The multivariable logistic regression analysis showed that obscure tumor-lung interface (odds ratio (OR = 20.930, P < 0.05), air-bronchogram or vacuole sign (OR = 7.126, P < 0.05), spiculation sign (OR = 4.207, P < 0.05), and vessel abnormalities (OR = 0.147, P < 0.05) were the main influencing factors. The prediction model based on those factors’ regression coefficients had an area under the ROC curve of 0.829 (P < 0.05). Conclusion Compared with those with NIMA, patients with solitary nodular IMA in stage IA were older and more likely to have the CT features of obscure tumor-lung interface, air-bronchogram or vacuole sign, and longer and softer spiculation. Based on the regression coefficients of tumor-lung interface, air-bronchogram or vacuole sign, spiculation, and vessel abnormalities, the risk score prediction model showed good predictive performance for solitary nodular IMA.

Objective:To evaluate the efficacy and prognostic factors of 125I seeds implantation for primary hepatocellular carcinoma. Methods:From December 2011 to January 2021, 102 primary hepatocellular carcinoma patients (86 males, 16 females; median age 61 years) who underwent 125I seeds implantation from 5 hospitals in China were enrolled in this retrospective study. Local progression-free survival (LPFS), overall survival (OS) and the prognostic factors were analyzed. Kaplan-Meier method was used to draw the distribution curve of survival time, and LPFS rate and OS rate were calculated. Log-rank test and Cox regression were used to analyze the influencing factors of survival. Results:The median follow-up time was 38 months until April 2021. The local control rate was 96.1%(98/102). The 1-, 3- and 5-year LPFS rate were 61.3%, 25.5% and 12.7%, and the 1-, 3- and 5-year OS rate were 73.9%, 39.1% and 22.6%, respectively. There were 75 patients with progressive disease, including 42 patients with intrahepatic recurrence and metastasis after seed implantation, and 55 patients died. Multivariate analyses showed that short-term efficacy complete response (CR) (hazard ratio ( HR)=0.34, 95% CI: 0.20-0.58) was protective factor related to LPFS; short-term efficacy CR ( HR=0.25, 95% CI: 0.13-0.47) was the protective factors related to OS; Barcelona clinic liver cancer (BCLC) C stage ( HR=2.33, 95% CI: 1.27-4.27), intrahepatic progression and extrahepatic metastasis ( HR=3.18, 95% CI: 1.28-7.86; HR=3.23, 95% CI: 1.27-8.21) were independent risk factors related to OS. No sever adverse effects were observed. Conclusions:125I seeds implantation is safe and effective for the treatment of primary hepatocellular carcinoma. BCLC stage, short-term efficacy and post-implantation progression are independent factors related to survival time.
