Visualization of therapeutic intervention for acute liver injury using low-intensity pulsed ultrasound-responsive phase variant nanoparticles.

Acute liver injury (ALI) is a highly fatal condition characterized by sudden massive necrosis of liver cells, inflammation, and impaired coagulation function. Currently, the primary clinical approach for managing ALI involves symptom management based on the underlying causes. The association between excessive reactive oxygen species originating from macrophages and acute liver injury is noteworthy.

Giant renal schwannoma with obvious hemorrhage and cystic degeneration: a case report and literature review.

Background: Renal schwannomas are very rare and are usually benign. Its clinical symptoms and imaging features are nonspecific, and the diagnosis is usually confirmed by pathology after surgical resection.

Case Presentation: A 46-year-old Chinese female was admitted to the hospital with right flank pain that had persisted for the six months prior to admission.

Small (≤ 20 mm) ground-glass opacity pulmonary lesions: which factors influence the diagnostic accuracy of CT-guided percutaneous core needle biopsy?

Background: The diagnostic accuracy of computed tomography (CT)-guided percutaneous core needle biopsy (CNB) for small (≤ 20 mm) ground-glass opacity (GGO) lesions has not been reported in detail.

Objectives: To evaluate factors that affect the diagnostic accuracy of CT-guided percutaneous CNB for small (≤ 20 mm) GGO pulmonary lesions.

Methods: From January 2014 to February 2018, 156 patients with a small (≤ 20 mm) GGO pulmonary lesion who underwent CT-guided CNB were enrolled in this study.

Asialoglycoprotein Receptor-Targeted Superparamagnetic Perfluorooctylbromide Nanoparticles.

Background: The decrease in asialoglycoprotein receptor (ASGPR) levels is observed in patients with chronic liver disease and liver tumor. The aim of our study was to develop ASGPR-targeted superparamagnetic perfluorooctylbromide nanoparticles (M-PFONP) and wonder whether this composite agent could target buffalo rat liver (BRL) cells in vitro and could improve 2 value of the rat liver parenchyma after its injection in vivo.

Methods: GalPLL, a ligand of ASGPR, was synthesized by reductive amination.

Comparison of graphical optimization or IPSA for improving brachytheraphy plans associated with inadequate target coverage for cervical cancer.

Many studies have reported that inverse planning by simulated annealing (IPSA) can improve the quality of brachytherapy plans, and we wanted to examine whether IPSA could improve cervical cancer brachytherapy plans giving D < 6 Gy (with 7 Gy per fraction) at our institution. Various IPSA plans involving the tandem and ovoid applicators were developed for 30 consecutive cervical cancer patients on the basis of computed tomography: IPSA1, with a constraint on the maximum dose in the target volume; IPSA1-0, identical to IPSA1 but without a dwell-time deviation constraint; IPSA2, without a constraint on the maximum dose; and IPSA2-0, identical to IPSA2 but without a dwell-time deviation constraint. IPSA2 achieved similar results as graphical optimization, and none of the other IPSA plans was significantly better than graphical optimization.

[Study on the soft-wood cutting of Atractylodes macrocephala].

Objective: The research analyzed the effect of different elements on soft-wood cutting of Atractylodes macrocephala.

Methods: The experiment was studied by L9 (3(4)) orthogonal design with 3 factors and 3 levels. The research confirmed the best project of soft-wood cutting of Atractylodes macrocephala by using variance analysis and line grading law.

[The change rules and correlation between specific leaf weight and dry weight of rhizoma of Atractylodes macrocephala].

Objective: To study the change rules of specific leaf weight, dry weight of rhizoma and the drying rate of annual and biennial Atractylodes macrocephala.

Methods: We measured the specific leaf weight and dry weight of rhizoma, and accounted the drying rate and correlation by dugging the annual and biennial plants each 15 days. There were 3 rhizoma types of biennial Atractylodes macrocephala with Drumstick/Frog type, Er-cha type and Wu-zi type.
