In Vitro Fertilization and Hearing Impairment in Twins.

Objective: This study investigates the potential correlation between in vitro fertilization (IVF) and hearing impairment in twins compared to naturally conceived twins.

Method: Analyzing data from 2416 twin infants born between 2019 and 2021. Analyze the pregnancy conditions and complications of mothers, the birth conditions of newborns, perinatal diseases, initial hearing screening results, and subsequent follow-up conditions.

Acute pancreatitis and refractory hypercalcemia in the third trimester caused by parathyroid carcinoma.

Background: Hypercalcemia can be a rare contributor to acute pancreatitis (AP) in pregnancy. This is primarily due to primary hyperparathyroidism (PHPT), resulting from parathyroid carcinoma. We exhibited a case report to analyze the diagnosis and treatment during the onset of hypercalcemia-induced AP.

Evaluation of subjective visual vertical and horizontal in patients with acoustic neuroma based on virtual reality.

Objective: To investigate potential differences in absolute deviation values of subjective visual vertical and horizontal between unilateral acoustic neuroma patients and healthy young adults under varying degrees of static head tilt, as well as the impact of proprioception on these values, with the aim of determining the effect of acoustic neuroma on gravity sensory pathway function in patients.

Methods: We recruited 22 patients diagnosed with unilateral acoustic neuroma and 25 healthy young adults and employed virtual reality technology to assess the absolute deviation values of subjective visual vertical (SVV) and subjective visual horizontal (SVH) under eight different static tilted head positions (Head centered (0° tilt), PdP, Head tilt 15°, 30°, 45° to the left and right), then compare and analyze intergroup differences.

Results: In the Head-centered position, both SVV and SVH absolute deviated values were significantly higher in the AN group compared to healthy young adults.

Novel long non-coding RNA lncAMPC downregulates PTEN via miR-214 to promote nasopharyngeal carcinoma progression.

Long non-coding RNAs (lncRNAs) are a type of non-coding RNAs with transcript lengths exceeding 200 nt. lncRNAs suppress or promote cancer mainly by regulating gene expression. The aim of this study was to explore the role of lncRNAs activated in metastatic PCa (lncAMPC) in nasopharyngeal carcinoma (NPC).

[Detection of hearing threshold and polymorphic molecular marker analysis of guinea pigs of mimetic aging].

Objective: To explore the establishment of the mimetic aging effect in guinea pigs induced by D-galactose, and to detect the biological indicatrix associated with hearing loss and provide a new tool for molecular pathogenesis of hearing loss.

Methods: Total of 51 guinea pigs were randomly divided into three groups: group A (model aging group, n = 25), which were injected with D-galactose (200 mgxkg(-1)xd(-1)) by intra peritoneum for 6 weeks, group B (model control group, n = 18), which were given the same amount of saline only, and group C (vacant group, n = 15) were not treated. Then, The guinea pigs in group A and B were exposed in noise for 8 days, 8 hours once a day.
