Enhancing glioma-specific drug delivery through self-assembly of macrophage membrane and targeted polymer assisted by low-frequency ultrasound irradiation.

The blood-brain Barrier (BBB), combined with immune clearance, contributes to the low efficacy of drug delivery and suboptimal treatment outcomes in glioma. Here, we propose a novel approach that combines the self-assembly of mouse bone marrow-derived macrophage membrane with a targeted positive charge polymer (An-PEI), along with low-frequency ultrasound (LFU) irradiation, to achieve efficient and safe therapy for glioma. Our findings demonstrate the efficacy of a charge-induced self-assembly strategy, resulting in a stable co-delivery nanosystem with a high drug loading efficiency of 44.

A nomogram incorporating clinical, conventional ultrasound and shear wave elastography findings for distinguishing pleomorphic adenoma from Warthin's tumor of the major salivary glands.

Objective: Pre-operative differentiation between pleomorphic adenoma (PA) and Warthin's tumor (WT) of the major salivary glands is crucial for treatment decisions. The purpose of this study was to develop and validate a nomogram incorporating clinical, conventional ultrasound (CUS) and shear wave elastography (SWE) features to differentiate PA from WT.

Methods: A total of 113 patients with histological diagnosis of PA or WT of the major salivary glands treated at Fujian Medical University Union Hospital were enrolled in training cohort ( = 75; PA = 41, WT = 34) and validation cohort ( = 38; PA = 22, WT = 16).

Contrast-Enhanced Ultrasound Imaging: Novel Method for the Evaluation of Chronic Alcohol-Induced Testicular Damage.

Objective: The goals of this study were to determine whether contrast-enhanced ultrasound (CEUS) imaging could be used for assessment of chronic alcohol-induced testicular damage (CAITD) and to explore the relationships between the laboratory and pathological findings of CAITD and the quantitative parameters of CEUS.

Methods: Thirty-six rabbits were randomly divided into a chronic ethanol exposure (CEE) group and negative control (NC) group, which were further randomly divided into six groups with equal numbers of rabbits by period of exposure (30 d, 60 d, 90 d). All rabbits underwent conventional US and CEUS imaging at the end of the induction period.

Cost analysis of supply chain management of Da Vinci surgical instruments: A retrospective study.

Background: Da Vinci surgery is used extensively, but the high costs of the surgical instrument are a serious clinical and management problem.

Objective: To reduce the cost of the Da Vinci robotic surgical instrument supply chain.

Methods: Patients were selected from the First Affiliated Hospital of Sun Yat-sen University, Guangzhou, China.

Wheat embryo globulin nutrients ameliorate d-galactose and aluminum chloride-induced cognitive impairment in rats.

Wheat embryo globulin nutrient (WEGN), with wheat embryo globulin (WEG) as the main functional component, is a nutritional combination that specifically targets memory impairment. In this study, we explored the protective role of WEGN on Alzheimer's disease (AD)-triggered cognitive impairment, neuronal injury, oxidative stress, and acetylcholine system disorder. Specifically, we established an AD model via administration of d-galactose (d-gal) and Aluminum chloride (AlCl) for 70 days, then on the 36th day, administered animals in the donepezil and WEGN (300, 600, and 900 mg/kg) groups with drugs by gavage for 35 days.

Hypolipidemic effect of Alisma orientale (Sam.) Juzep on gut microecology and liver transcriptome in diabetic rats.

Alisma orientale (Sam.) Juzep (A. orientale) is a traditional herb that is often used to treat disease including edema and hyperlipidemia.

Using shear wave elastography method to evaluate testicular compartment syndrome after testicular torsion.

The measurement of compartment pressure is a direct method to objectively evaluate suspected compartment syndrome. However, to evaluate the evolving compartment syndrome, one needs to measure the pressure repeatedly, which may aggravate the damage of tissue. Despite several suggested approaches, an effective, noninvasive and sustainable method to detect testicular compartment syndrome is still lacking.

Opposite effects of high- and low-dose di-(2-ethylhexyl) phthalate (DEHP) exposure on puberty onset, oestrous cycle regularity and hypothalamic kisspeptin expression in female rats.

Di-(2-ethylhexyl) phthalate (DEHP) is ubiquitous in the environment and has been proposed to lead to reproductive disruption. In this study, we systematically investigated the effects of different doses of DEHP exposure on female hypothalamic-pituitary-gonadal axis development. Female Sprague-Dawley rats were gavaged with vehicle (corn oil) or DEHP (5 or 500mgkg-1 day-1) during postnatal Days (PNDs) 22-28 or PNDs 22-70.

[Correlation study between accumulation of triterpenoids and expression of relative genes in Alisma orientale].

To research the correlation between accumulation of triterpenoids and expression of key enzymes genes in triterpenoid biosynthesis of Alisma orientale,the study utilized UPLC-MS/MS method to detect eight triterpenoids content in the tuber of A. orientale from different growth stages,including alisol A,alisol A 24 acetate,alisol B,alisol B 23 acetate,alisol C 23 acetate,alisol F,alisol F 24 acetate and alisol G,and then the Real time quantitative PCR was used to analyze the expression of key enzymes genes HMGR and FPPS in triterpenoid biosynthesis. Correlation analysis showed that there was a significant positive relation between the total growth of these eight triterpenoids and the average relative expression of HMGR and FPPS(HMGR: r = 0.
