Objective To explore the predictive value of preoperative prognostic nutritional index(PNI)for postoperative out-comes of patients with hepatocellular carcinoma(HCC)undergoing transarterial chemoembolization(TACE).Methods The clinical datas of 142 HCC patients treated with TACE as initial treatment were retrospectively collected.According to the cut-off value deter-mined by the receiver operating characteristic(ROC)curve,the preoperative systemic immune-inflammation index(SII),PNI,aspar-tate aminotransferase-neutrophil ratio(ANRI),aspartate aminotransferase-lymphocyte ratio(ALRI)and aspartate aminotransferase-platelet ratio(APRI)were divided into high group and low group,and their effects of TACE on postoperative outcome were ana-lyzed.Results Preoperative PNI was negatively correlated with liver function 1 week after TACE.Preoperative PNI and tumor size were independent risk factors for overall survival(OS).The PNI≥42.35 group was better than PNI<42.35 group(OS 28 months vs 10 months),the tumor size<5 cm was better than tumor size≥5 cm(OS 37 months vs 11 months),and the differences were statistically significant(P<0.05).PNI was an independent risk factor for progression-free survival(PFS).The PNI≥42.35 group was better than PNI<42.35 group(PFS 6 months vs 3 months),and the difference was statistically significant(P<0.05).Conclusion Preop-erative PNI has a certain prognostic value in HCC patients,and the OS and PFS of HCC patients with PNI<42.35 group after TACE are shorter.

Objective To discuss the application of partial antiplatelet drug genotype detection and thromboelastography-platelet mapping(TEG-PM)in guiding the selection of antiplatelet regimens in patients with intracranial aneurysms(IAs)after receiving stenting.Methods A total of 106 patients with IAs in the First Affiliated Hospital of Kunming Medical University,who underwent implantation of stent and received the testings of platelet-endothelial aggregation receptor 1(PEAR 1)and clopidogrel-related gene-cytochrome P450 enzyme 2C19(CYP2C19),and some of whom received TEG-PM testing from January 2019 to August 2022,were collected for this study.The patients were divided into group A(gene detection group,according to the drug-related gene detection results to adjust the medication)and group B(combination group,according to the two testing results to guide the medication).The patient's gender,age,testing data were collected,and the occlusion of IAs,stent intimal hyperplasia,drug-related hemorrhagic and ischemic complications during follow-up period were recorded.Results A total of 123 IAs lesions in 106 patients were treated.The patient's mean age was(53.67±6.66)years,67 patients were female.Group A had 41 patients and group B had 65 patients.No statistically significant differences in the baseline data,IAs features,stent types used,and medication regimen existed between the two groups(all P＞0.05).In Group A,the ischemic complications and hemorrhagic complications occurred in two patients each.In Group B,no ischemic complications occurred and 4 patients developed hemorrhagic complications.The difference in the incidence of related complications between the two groups was not statistically significant(P=0.287 and P=0.782 respectively).There were no statistically significant differences in the postoperative one-month and 3-month intimal hyperplasia grade and the aneurysm occlusion rate between the two groups(all P＞0.05).The postoperative 6-month overall intimal hyperplasia grade in Group A was slightly higher than that in Group B,and the difference was statistically significant(P=0.034).Conclusion In order to improve the precision and individualized treatment of antiplatelet therapy,it is suggested that clinicians should adopt TEG-PM-guided conventional double-antibody therapy first when making selection of testing items.For patients with insufficient inhibition rate indicated by TEG-PM,testing of the genes associated with antiplatelet drugs should be used.Based on the genetic test results it is necessary to determine the reasons for the insufficient inhibition rate as well as to adjust the medication promptly according to the specific situation of the patient,so as to ensure the effectiveness of antiplatelet therapy and achieve the purpose of individualized precision therapy.

Objective To compare the differences in efficacy and safety between transarterial chemoembolization(TACE)com-bined with lenvatinib and camrelizumab(triple therapy)and TACE combined with lenvatinib(double therapy)in intermediate or advanced stage hepatocellular carcinoma(HCC).Methods The clinical data of 145 patients who were diagnosed with HCC and received triple therapy or double therapy were retrospectively collected.The differences of objective response rate(ORR),disease control rate(DCR),median progression-free survival(mPFS),median overall survival(mOS),and adverse events were compared between the two groups.Results The ORR and DCR in 1,3 and 6 months of the triple therapy group were higher than those of the double therapy group,and the differences were statistically significant in 3 and 6 months.The mPFS and mOS of the triple therapy group were higher than those of the double therapy group,and the differences were statistically significant.The Cox proportional hazards model results showed that the therapy methods,maximum tumor diameter and alpha-fetoprotein(AFP)were independent risk factors of progres-sion-free survival(PFS)and overall survival(OS).Besides,Barcelona Clinic Liver Cancer(BCLC)staging was independent risk fac-tor of OS.In terms of adverse events,the incidence of reactive cutaneous capillary endothelial proliferation(RCCEP)and hypothy-roidism in the triple therapy group were higher than those in the double therapy group,and the differences were statistically signifi-cant.Conclusion Compared with double therapy,triple therapy can significantly improve the efficacy of intermediate or advanced stage HCC,prolong patients'PFS and OS,and its safety can be well controlled.

The prognosis of hepatocellular carcinoma(HCC)may be different in a great degree,and accurate predicting prognosis is helpful for carrying out individualized and precise treatment.With the developments of artificial intelligence,radiomics and deep learning(DL)were widely used,providing valuable information for diagnosis and treatment of HCC through mining higher dimensional quantitative features on medical images.The research progresses of radiomics and DL for predicting prognosis of HCC were reviewed in this article.

Objective To compare high-intensity focused ultrasound (HIFU) ablation effect on uterine fibroids between patients with different uterus positions. Methods The clinical data of 372 patients with symptomatic uterine fibroids, who were treated with HIFU at authors' hospital, were retrospectively analyzed. According to the position of the uterus, the patients were divided into anteverted group, mid-position group and retroverted group. Single factor analysis of variance was used to compare the baseline data of fibroids and HIFU ablation results between each other among the three groups. Results Successful HIFU treatment was accomplished in all patients. The average age of the patients was (39±6) years. Single factor analysis of variance indicated that no statistically significant difference in baseline data of fibroids existed between each other among the three groups (P>0.05) . The one cm3 sonication time and energy efficiency factor (EEF) in the anteverted group were significantly smaller than those in the retroverted group, the differences were statistically significant (P =0.007 and P =0.017 respectively) . Conclusion Uterine fibroids within an anteverted uterus are more likely to be ablated by HIFU.

Objective To explore the value of interventional therapy in unruptured intracranial aneurysms combined with brain arteriovenous malformations (BAVM).Methods Data of 23 patients with unruptured aneurysms combined with BAVM were retrospectively analyzed.All patients were treated with interventional embolization,and the embolization methods were choosen according to the Redekop classification.The proximal or distal hemodynamic aneurysms were embolized with coils,and the intranidal aneurysms were embolized with Onyx.The outcome was assessed by the Glasgow outcome score (GOS) one week after treatment.DSA scan was used to observe whether there was recurrence during 3-6 months after embolization.Results Totally there were 36 aneurysms in 23 patients,including 8 intranidal aneurysms,16 proximal flow-related aneurysms,11 distal flow-related aneurysms and 1 unrelated aneurysm.Embolizations of 16 proximal hemodynamic aneurysms and l0 distal hemodynamic aneurysms were done with coils.And embolization of 8 intranidal aneurysms were done with Onyx.One distal hemodynamic aneurysm was not embolized due to the difficulty of embolization and the regular shap of aneurysm;and the patient died of cerebral hernia caused by intracranial hemorrhage on the sixth day after embolization.Because it was more suitable for surgical clipping,1 unrelated hemodynamic aneurysm was not embolized.In 23 cases,BAVM were completely embolized in 7 cases and incompletely embolized in 16 cases.A week after operation,the GOS score were 5 in 19 cases and 4 in 3 cases.The GOS score was not evaluated in the dead case.Except for 1 cases of death,the other 22 cases were followed up after embolization.No recurrence and intracranial hemorrhage occurred.Conclusion Interventional treatment of unruptured intracranial aneurysms combined with BAVM is safe and effective.Making treatment plan according to the hemodynamic characteristics of lesions and completely embolizing all lesions to prevent postoperative bleeding is helpful to improve the prognosis of patients.

Objective To investigate the value of parametric imaging of CEUS in uterine fibroids with different signal intensity on T2WI by high intensity focused ultrasound (HIFU),and dynamic vascular pattern (DVP).Methods Totally 16 patients with single uterine fibroids were divided into high intensity group (n=6),isointensity group (n=4) and low intensity group (n=6) according the signal intensity on T2WI before HIFU treatment.CEUS were performed on each patient.SonoLive CAP software was used to analyze the CEUS images and DVP parametric images were reconstructed.Results The maximum intensity,rising time,time to peak and mean transit time were (235.40± 35.46)％,(22.80± 3.16)s,(25.09±2.44)s,(125.78 ± 27.63)s in high intensity group,(71.97± 2.43) ％,(24.85±3.22)s,(32.81±3.92)s,(66.52±3.48)s in isointensity group and (16.17±2.83) ％,(25.42±2.66)s,(32.82±3.76)s,(64.27±3.33)s in low intensity group.There were statistically significant differences among three groups (all P＜0.05).DVP curve was divided into two types:non-washout in high intensity group and cystic type in low intensity group.Conclusion CEUS and DVP imaging can directly quantitively display the difference of blood perfusion among the uterine fibroids with different signal intensity on T2WI which can provide important information for HIFU treatment in uterine fibroids.

Objective To evaluate clinical value of ultrasound contrast agent the sulfur hexafluoride micro-bubble in the treatment of T2WI high signal uterine fibroids with high intensity focused ultrasound (HIFU).Methods A total of 36 patients with T2WI high signal uterine fibroids were randomly divided into experimental group and control group.Eighteen patients in experimental group received HIFU treatment with sulfur hexafluoride micro-bubble before,during and after the operation while another eighteen in control group received HIFU treatment with sulfur hexafluoride micro-bubble only after the operation.We recorded operation time (min),changing time of massive gray (s),irradiation time (s),therapeutic dose (J),incidence of complications and ablation rate (％).Results Operation time,changing time of massive gray,irradiation time,and therapeutic dose in experimental group were (101.51±43.02) min,(856.42±451.14) s,(1077.37±546.23) s,and (496581.81 ± 267192.31) J,respectively while those in control group were (261.34 ± 85.53) min,(1 833.32 ± 642.67) s,(1 890.21 ± 1 268.43) s,and (784 608.31 ± 357 621.45) J,respectively.Significant differences were found among those parameters between the two groups (P ＜0.05).Tumor ablation rate in experimental group was 83.3％ while that in control group was 55.5％,which was of significant difference between the two groups (P＜0.05).One case of muscular stiffness was found in experimental group while one case of second-degree burn and two cases of muscular stiffness were found in the control group.The incidence of complications was 1/18 (5.5％).No severe complication like bowel perforation or bladder perforation was found in the two groups.Conclusion The effect of ultrasound contrast agent sulfur hexafluoride micro-bubble can shorten operation time,improve tumor ablation rate and reduce complications and it can play a guiding role in clinical work.
