Efficacy of wearable transcutaneous electrical acupoint stimulation bracelet on moderate-to-severe postoperative nausea and vomiting in patients after general anesthesia: a study protocol for a multicenter randomized controlled trial.

Background: Postoperative nausea and vomiting (PONV) is the most common complication following general anesthesia. Currently, pharmaceutical therapy is the primary method of treatment, but it has reached a plateau, and it is accompanied by inherent adverse reactions and high costs. Stimulation of the wrist acupuncture point PC6 is recommended as an effective means of preventing PONV.

Fibroblast growth factor 21 attenuates ventilator-induced lung injury by inhibiting the NLRP3/caspase-1/GSDMD pyroptotic pathway.

Background: Ventilator-induced lung injury (VILI) is caused by overdistension of the alveoli by the repetitive recruitment and derecruitment of alveolar units. This study aims to investigate the potential role and mechanism of fibroblast growth factor 21 (FGF21), a metabolic regulator secreted by the liver, in VILI development.

Methods: Serum FGF21 concentrations were determined in patients undergoing mechanical ventilation during general anesthesia and in a mouse VILI model.

Changes in innate and permissive immune responses after hbv transgenic mouse vaccination and long-term-siRNA treatment [corrected].

Background: Currently, no licensed therapy can thoroughly eradicate hepatitis B virus (HBV) from the body, including interferon α and inhibitors of HBV reverse-transcription. Small interfering RNA (siRNA) seem to be a promising tool for treating HBV, but had no effect on the pre-existing HBV covalently closed circular DNA. Because it is very difficult to thoroughly eradicate HBV with unique siRNAs, upgrading the immune response is the best method for fighting HBV infection.

[Effects of Wuling mycelia on pentylenetetrazole-induced epilepsy in rats].

Objective: To investigate the effects and mechanisms of Wuling mycelia on seizure development and learning ability induced by pentylenetetrazole-kindling epilepsy in rats.

Methods: SD rats were randomly divided into four groups: pentylenetetrazole-kindling model group (model group), low dose Wuling mycelia (0.3 g*kg(-1)) group (LD-WM group), high dose Wuling mycelia (0.

[Epidemiological and clinical analysis of Mycoplasma pneumoniae infection in children with acute respiratory tract infection].

Objective: To summarize the epidemiology and clinical characteristics of Mycoplasma pneumoniae (MP) infection in children with acute respiratory tract infection (ARI) in Guangzhou.

Methods: MP was detected using an indirect immunofluorescent method in 2084 children with ARI. The relations between MP infection rate and the gender, age, season, site of infection and wheezing diseases were analyzed.

The short hairpin RNA driven by polymerase II suppresses both wild-type and lamivudine-resistant hepatitis B virus strains.

Background: Chronic infection with hepatitis B virus (HBV) is widespread because of the limited availability of therapeutic treatments. Although previous reports have suggested that RNA interference has promise as a treatment for HBV infection, further studies of long-term and off-target drug effects on HBV, especially on drug-resistant strains of HBV, are needed. Therefore, seven vectors that express short hairpin RNAs (shRNAs), driven by the polymerase II promoter, pSilencer4.

Toll-like receptor 4 siRNA attenuates LPS-induced secretion of inflammatory cytokines and chemokines by macrophages.

Toll-like receptor 4 (TLR4) is critical for activation of macrophages by Lipopolysaccharide (LPS). In this study, we investigated the silencing effects of TLR4-specific 21-nt small interfering RNAs (siRNA) on TLR4 expression in RAW264.7 cells.

Effects of insulin-like growth factor I on the development of osteoblasts in hyperglycemia.

The delayed wound healing of tooth extraction, the activation of alveolar absorption and the being hindered bone formation around the implants in diabetes are difficult to be solved for dentists. So, the aim of the study was to investigate the influences of hyperglycemia and insulin-like growth factor I (IGF-I) on osteoblasts. Osteoblasts were cultured in different conditions: normal glucose, mimic hyperglycemia, hyperglycemia with IGF-I, hyperglycemia with insulin.

Stable inhibition of hepatitis B virus expression and replication by expressed siRNA.

RNA interference might be an efficient antiviral therapy for some obstinate illness. Here, we studied the effects of hepatitis B virus (HBV)-specific 21-nt small interfering RNAs (siRNA) on HBV gene expression and replication in 2.2.
