Case Report: Imaging features of a new type double inferior vena cava malformation and review.

Background: Double inferior vena cava (DIVC) is a rare vascular malformation. With advances in radiological techniques and diagnosis, more and more types of DIVC were identified and diagnosed. Recognition of the variety of DIVC seen on imaging is essential for subsequent venous interventions.

Safety and Efficacy of Drug-Eluting Bead Transarterial Chemoembolization Combined with Lenvatinib and Anti-PD-1 Antibodies for Unresectable Hepatocellular Carcinoma: A Retrospective Analysis.

Background: Drug-eluting bead transarterial chemoembolization (DEB-TACE) has good efficacy in the treatment of unresectable hepatocellular carcinoma (uHCC), with a relatively high objective response rate (ORR) compared to conventional transarterial chemoembolization (cTACE). This study aimed to evaluate the safety and medium-term clinical efficacy of DEB-TACE combined with lenvatinib (LEN) plus PD-1 inhibitors as a triple therapy for the treatment of uHCC.

Methods: Data of patients with uHCC who received triple therapy of DEB-TACE combined with LEN plus PD-1 inhibitors from January 2019 to June 2021 were analyzed retrospectively.

Retrospective Analysis of the Effect of Lidocaine Combined with Methylprednisolone on Pain Control After Uterine Artery Embolization.

Background: The analgesic effect produced by the intra-arterial injection of lidocaine in patients undergoing uterine artery embolization has been proven to be safe and effective. Nevertheless, a significant degree of pain is typically experienced after the operation, and pain management is crucial. Methylprednisolone, which provides an anti-inflammatory effect, is widely used in the treatment of several diseases.

Rare Cases of Bronchial Aneurysm and Comparison of Interventional Embolization in the Treatment of True Bronchial Aneurysm and Pseudobronchial Aneurysm.

Background: Bronchial artery aneurysm (BAA) is a rare disease. Rupture of BAA can lead to life-threatening hemoptysis, and once diagnosed, treatment is needed regardless of symptoms. Transcatheter artery embolization is the first choice of treatment because it is minimally invasive and effective.

Clinical outcomes of uterine artery embolization and experience of postoperative transvaginal fibroid expulsion: a retrospective analysis.

Purpose: To explore the efficacy of uterine artery embolization (UAE) in the treatment of uterine fibroid and share the experience of transvaginal fibroid expulsion (FE) after UAE.

Methods: We retrospectively analyzed the changes in uterine and fibroid volume in 152 patients with symptomatic uterine fibroid after UAE at Fujian Provincial Hospital and Fujian Longyan People Hospital from March 2014 to March 2020. After a 12-month follow-up, the improvement in postoperative clinical symptoms and the incidence of complications were evaluated.

A thrombophilia family with protein S deficiency due to protein translation disorders caused by a Leu607Ser heterozygous mutation in PROS1.

Background: Protein S deficiency (PSD) is an autosomal dominant hereditary disease. In 1984, familial PSD was reported to be prone to recurrent thrombosis. Follow-up studies have shown that heterozygous protein S (PROS1) mutations increase the risk of thrombosis.

Retrospective observation of the efficacy and safety of prostatic artery embolization combined with transurethral resection of the prostate and simple transurethral resection of the prostate in the treatment of large (> 100 mL) benign prostatic hyperplasia.

Purpose: To retrospectively compare the efficacy and safety of prostatic artery embolization (PAE) combined with transurethral resection of the prostate (TURP) and simple TURP in treating large (> 100 mL) benign prostatic hyperplasia (BPH).

Methods: We retrospectively analyzed the clinical data of 13 and 17 patients with large BPH who underwent TURP and PAE + TURP, respectively, from January 2016 to January 2020. The changes in various indices before and after surgery were compared between the two groups.

Effect of superselective prostatic artery embolization on benign prostatic hyperplasia.

Purpose: To investigate the safety and effectiveness of superselective prostatic artery embolization (PAE) in patients with benign prostatic hyperplasia (BPH).

Methods: Sixty-five patients diagnosed with BPH in Fujian Provincial Hospital between December 2014 and July 2019 were included. Patients with ineffective drug treatment after 6 months, who refused surgery, or who were unsuitable for surgery were included.

Organocatalytic Aza-Michael/Michael Cyclization Cascade Reaction: Enantioselective Synthesis of Spiro-oxindole Piperidin-2-one Derivatives.

A simple, direct, and highly enantioselective synthesis of spiro-oxindole piperidin-2-one derivatives was achieved through an aza-Michael/Michael cyclization cascade sequence using a squaramide catalyst. The desired products were obtained in excellent yields (up to 99%) and good to high stereoselectivities (up to >20:1 dr and up to 99% ee) under mild conditions.

Asymmetric Total Syntheses of (-)-α-Lycorane, (-)-Zephyranthine, and Formal Synthesis of (+)-Clivonine.

An asymmetric route to (-)-α-lycorane and (-)-zephyranthine, and a formal total synthesis of (+)-clivonine were achieved. A pivotal intermediate, which serves as a potent precursor for the divergent syntheses of these natural products, was accessed by a diastereoselective Pd-catalyzed cinnamylation of an N-tert-butanesulfinyl imine.

Asymmetric cinnamylation of N-tert-butanesulfinyl imines with cinnamyl acetates: total syntheses of (+)-lycoricidine and (+)-7-deoxypancratistatin.

Highly diastereoselective palladium catalyzed cinnamylation of N-tert-butanesulfinyl imines with cinnamyl acetates has been established to provide enantioenriched β-aryl homoallylic amines. The synthetic application of this stragety has been successfully demonstrated in the concise total syntheses of antitumor natural products (+)-lycoricidine and (+)-7-deoxypancratistatin.

Practical Asymmetric Synthesis of Amathaspiramides B, D, and F.

The practical asymmetric synthesis of amathaspiramides B, D, and F has been accomplished by utilizing an aza-Barbier allylation as the key step to construct the common intermediate with two adjacent stereocenters. A kinetically controlled cyclization to build the challenging thermodynamically less stable 8R-hemiaminal moiety is also important in the synthesis of amathaspiramide D. The route is readily scalable, and gram quantity of the final product D has been prepared.
