Effect of transcutaneous electrical acupoint stimulation based on the theory of " ascending and descending movement" on autonomic nervous system and gastrointestinal function in patients after general anesthesia laparoscopic cholecystectomy.

Objectives: To observe the therapeutic effect of transcutaneous electrical acupoint stimulation (TEAS) based on the theory of " ascending and descending movement" in patients after general anesthesia laparoscopic cholecystectomy, so as to explore the impact of TEAS on the autonomic nervous system and gastrointestinal function of patients.

Methods: A total of 204 patients scheduled to undergo general anesthesia laparoscopic cholecystectomy were selected and randomly divided into control, double acupoints and multiple acupoints groups, with 68 cases in each group. For patients in the multiple acupoints group, TEAS was applied at Zusanli (ST36), Tiantu (CV22), Danzhong (CV17), Zhongwan (CV12), Taichong (LR3), and Neiguan (PC6) 30 min before anesthesia induction until the end of the surgery.

[Characteristics，Sources，and Ozone-sensitive Species of VOCs in Four Seasons in Yuncheng].

Based on the one-year observational data of volatile organic compounds （VOCs） in an urban area of Yuncheng in 2021， the concentration， composition， sources， and ozone-sensitive species of VOCs in four seasons were analyzed. The results showed that the average annual concentration of VOCs was （32.1 ±24.

Differences in the predictive value of red cell distribution width for the mortality of patients with heart failure due to various heart diseases.

Background: Increased red blood cell distribution width (RDW) is associated with adverse outcomes in patients with heart failure (HF). The objective of this study was to compare the differences in the predictive value of RDW in patients with HF due to different causes.

Methods: We retrospectively investigated 1,021 HF patients from October 2009 to December 2011 at Fuwai Hospital (Beijing, China).

Neuregulin-1 attenuates doxorubicin-induced autophagy in neonatal rat cardiomyocytes.

Recombinant human neuregulin-1 (rhNRG-1) improves cardiac function in animal models of doxorubicin (DOX)-induced cardiomyopathy, but the underlying mechanism remains largely unknown. Here, we confirm a role for rhNRG-1 in attenuating DOX-induced autophagy and define the signaling pathways through which it mediates some of its effects. Neonatal rat ventricular myocytes were subjected to different treatments both to induce autophagy and to determine the effects of rhNRG-1 on the process.
