Electron-phonon coupling and thermal transport properties of GaN/AlGaN heterojunction under strain regulation.

In the study of GaN/AlGaN heterostructure thermal transport, the interference of strain on carriers cannot be ignored. Although existing research has mainly focused on the intrinsic electronic and phonon behavior of the materials, there is a lack of studies on the transport characteristics of the electron-phonon coupling in heterostructures under strain control. This research comprehensively applies first-principles calculations and the Boltzmann transport equation simulation method to deeply analyze the thermal transport mechanism of the GaN/AlGaN heterojunction considering in-plane strain, with particular attention to the regulatory role of electron-phonon coupling on thermal transport.

Therapeutic Efficacy of Re-Lin-Qing Granules in Treating Type 2 Diabetes Mellitus Complicated with Urinary Tract Infection: A Retrospective Study.

Purpose: Urinary tract infections (UTIs) frequently occur in patients with type 2 diabetes mellitus (T2DM), presenting a complex pathogenesis that significantly impairs patient quality of life. Despite the availability of various clinical treatments, challenges remain regarding their efficacy and safety. Therefore, this retrospective study aimed to observe the therapeutic effects of Re-Lin-Qing granules in treating T2DM complicated by UTIs, aiming to provide more scientifically validated and effective treatment options for clinical practice.

Effect of Interventional Ultrasound in the Treatment of Postthyroidectomy Vocal Cord Dysfunction: A Preliminary Exploratory Study.

Purpose: To explore the efficacy of interventional ultrasound treatment for hoarseness caused by nondisconnected recurrent laryngeal nerve injury after thyroidectomy.

Materials And Methods: In this retrospective study, we analysed the clinical data of 21 patients who underwent interventional ultrasound therapy (ultrasound-guided injection of a Diprospan and saline mixture) for postthyroidectomy hoarseness at our hospital between August 1, 2023, and January 31, 2024 (the Diprospan group) and randomly selected 21 patients who did not receive any treatment for postthyroidectomy hoarseness during the same period as the control group. The average vocal cord activity improvement time for the Diprospan group was calculated and compared with that of untreated patients from previous studies.

Effects of Sodium Bicarbonate Ringer's Solution Combined with Positive End-Expiratory Pressure on the Internal Environment of Patients Undergoing Bariatric Surgery: A Randomized 2 × 2 Factorial Design Pilot.

Background: To evaluate the influence of sodium bicarbonate Ringer's solution (BRS) combined with positive end-expiratory pressure (PEEP) on the internal environment in patients who have undergone laparoscopic bariatric surgery.

Methods: A total of 128 patients undergoing laparoscopic bariatric surgery were randomly divided into the control group (group C), the PEEP group (group P), the BRS group (group B), and the BRS combined with the PEEP group (group BP). The results of arterial blood gas analysis, including pH value, base excess (BE), concentrations of electrolyte, and lactate (Lac) were documented before intravenous infusion (T0) and 5 min after the surgery (T1).
