[Expert consensus on ethical requirements for artificial intelligence (AI) processing medical data].

As artificial intelligence technology rapidly advances, its deployment within the medical sector presents substantial ethical challenges. Consequently, it becomes crucial to create a standardized, transparent, and secure framework for processing medical data. This includes setting the ethical boundaries for medical artificial intelligence and safeguarding both patient rights and data integrity.

Myeloid Angiotensin II Type 1 Receptor Mediates Macrophage Polarization and Promotes Vascular Injury in DOCA/Salt Hypertensive Mice.

Activation of the renin-angiotensin system has been implicated in hypertension. Angiotensin (Ang) II is a potent proinflammatory mediator. The present study investigated the role of myeloid angiotensin type 1 receptor (AT1R) in control of macrophage phenotype and vascular injury in deoxycorticosterone acetate (DOCA)/salt hypertension.

Atorvastatin activates autophagy and promotes neurological function recovery after spinal cord injury.

Atorvastatin, a lipid-lowering medication, provides neuroprotective effects, although the precise mechanisms of action remain unclear. Our previous studies confirmed activated autophagy following spinal cord injury, which was conducive to recovery of neurological functions. We hypothesized that atorvastatin could also activate autophagy after spinal cord injury, and subsequently improve recovery of neurological functions.

[Effects of salvia miltiorrhiza injection on gentamicin-induced expression of nitric oxide synthase isoforms in guinea pig cochlea].

Objective: To investigate the effects of salvia miltiorrhiza injection (SM) on gentamicin (GM)-induced expression of nitric oxide synthase (NOS) isoforms in guinea pig cochlea, and to explore the protective mechanism of SM on GM-induced ototoxicity.

Methods: 40 guinea pigs were randomly assigned to 4 groups: control group, GM group, SM group and GM plus SM group. Expression of NOS isoforms in the guinea pig cochlea was detected by the SABC method of immunohistochemistry and microscope image analysis technique.

A protective mechanism against antibiotic-induced ototoxicity: role of prestin.

Hearing loss or ototoxicity is one of the major side effects associated with the use of the antibiotics, particularly aminoglycosides (AGs), which are the most commonly used antibiotics worldwide. However, the molecular and cellular events involved in the antibiotic-induced ototoxicity remains unclear. In the present study, we test the possibility that prestin, the motor protein specifically expressed in the basolateral membrane of outer hair cells (OHCs) in the cochlea with electromotility responsible for sound amplification, may be involved in the process of AG-induced apoptosis in OHCs.

[Effect of cisplatin on apoptosis of spiral ganglion cell and expression of caspase-3 in mouse cochlea].

Objective: To establish a mice model of cisplatin-induced ototoxicity, and to investigate the effect of cisplatin on apoptosis of spiral ganglion cell and expression of caspase-3 in mouse cochlea.

Methods: Terminal deoxynucleotidyl transferase-mediated nick end labeling method (TUNEL) was used to monitor the apoptosis of spiral ganglion cell. Envision method of immunohistochemistry was applied to detect the expression of caspase-3 in cochlea.

[Effects of injectio Salvia miltiorrhiza on gentamicin-induced free radical formation in guinea pig cochlea].

Aim: To investigate the effects of injectio Salvia Miltiorrhiza (SM) on gentamicin (GM)-induced free radical formation in guinea pig cochlea, and to explore possible mechanisms on GM-induced ototoxicity.

Methods: Biochemical assays of superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in guinea pig cochlea, combined with auditory brainstem response (ABR) measurement and transmission electron microscopic observation were used in this investigation.

Results: SOD activity was significantly declined while MDA content was distinctly increased in cochlear tissues after GM injection (P < 0.

Tanshinone (Salviae miltiorrhizae extract) preparations attenuate aminoglycoside-induced free radical formation in vitro and ototoxicity in vivo.

Antioxidant therapy protects against aminoglycoside-induced ototoxicity in animal models. A clinically suitable antioxidant must not affect the therapeutic efficacy of aminoglycosides or exhibit any side effects of its own. In addition, the treatment should be inexpensive and convenient in order to be implemented in developing countries where the use of aminoglycosides is most common.
