Abstract

To investigate the efficacy of acupoint injection of Ropivacaine for labor analgesia and its effect on breastfeeding and prolactin secretion. A total of 80 primipara who asked to receive labor analgesia were randomized into epidural analgesia group (n=35) and acupoint injection group (n=36), and other 36 primipara who refused to receive labor analgesia were subjected to the control group. The labor analgesia began to be performed when the puerpera's uterine orifice opened about ≥3 cm (the first stage of labor), including puerpera controlled epidural analgesia (PCEA, Sufentainil + 0.1% Ropivacaine hydrochloride, 5 µg/mL at L3-L4 interspace, till the birth of fetus) or acupoint injection of Ropivacaine (0.2%, 1 mL/acupoint) at bilateral Hegu (LI4) and Sanyinjiao (SP6). The delivery situations such as the duration of labor, and number of cases who used oxytocin, obstetric-forceps-aided delivery, cesarean delivery were recorded. The serum prolactin concentration was assayed by using ELISA. The visual analogue scale (VAS) scores at the time points of T0 (about 3 cm widening of the orifice of uterus and before performing analgesia), T1 (30 min after labor analgesia), T2(about 10 cm widening of the orifice of uterus) and T3(coming out...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
