Hippocampal inflammatory responses in aged rats with POCD can be modulated by EA preconditioning, reducing neuronal apoptosis and long-term cognitive impairment. This modulation may stem from the suppression of the microglia HMGB1/NF-κB pathway within the hippocampal dentate gyrus.
In aged rats with POCD, EA preconditioning can favorably impact hippocampal inflammation, lessen neuronal apoptosis, and improve long-term cognitive abilities. This beneficial outcome could arise from the inhibition of the microglial HMGB1/NF-κB pathway within the dentate gyrus of the hippocampus.
Examining the influence of electroacupuncture (EA) on endometrial fibrosis and inflammatory response in a rat model of intrauterine adhesions (IUA) is the goal of this study, in order to investigate the potential mechanisms by which EA may contribute to IUA improvement and endometrial regeneration.
A total of forty-five female SD rats were randomly allocated to three groups (blank, model, and EA), each containing fifteen rats. The IUA model was established through a process combining mechanical scratching and lipopolysaccharide infection. In the EA group, bilateral electro-acupuncture at Zigong (EX-CA1) and Sanyinjiao (SP6), along with acupuncture at Guanyuan (CV4), was initiated two days after modeling. These treatments were administered once daily, lasting 15 minutes, throughout two consecutive estrous cycles. Samples from five rats per group were collected during the rats' estrus cycles. find more The application of hematoxylin and eosin stain prompted observation of changes in endometrial histopathology and gland count. Masson's staining allowed for a detailed observation and calculation of the endometrial fibrosis area. Immunohistochemical analysis revealed the presence of positive expressions of collagen type I (Col-I) and transforming growth factor 1 (TGF-1) proteins within the endometrial tissue. The protein expression of integrin 3 in uterine tissue was found to be present, as determined by a Western blot analysis. The concentration of interleukin (IL)-1 and tumor necrosis factor (TNF-) in uterine tissue was measured using the ELISA technique. To ascertain the number of implanted embryos, samples were collected from the remaining ten rats per group on day eight of gestation.
The rats in the blank group, during estrus, displayed a fully intact uterine structure, as confirmed by HE staining, with an obvious endometrial layer, an open and regular uterine cavity, and a profusion of glands. A destruction of the endometrial lining, a constricted and adherent uterine cavity, and scattered glands were identified in the model group; a notably milder response was observed in the EA group. The number of endometrial glands, the level of Integrin 3 protein, and the number of implanted uterine embryos were all significantly reduced in the model group's injured side, following the modeling procedure.
Elevated levels of endometrial fibrosis, along with elevated expressions of Col-I and TGF-1 proteins, and increased concentrations of IL-1 and TNF- were detected in the uterine tissue (001).
The blank group served as a benchmark, revealing marked distinctions compared to the experimental group. Substantial increases were noted in both the number of endometrial glands and the level of Integrin 3 protein expression, in addition to the number of implanted uterine embryos in the injured EA group after intervention.

By enhancing endometrial receptivity and regeneration, EA may improve embryo implantation outcomes in IUA rats. This potential mechanism may involve EA's influence on reducing endometrial fibrosis and inflammatory processes.
In IUA rat models, EA appears to improve endometrial receptivity, stimulating regeneration and encouraging embryo implantation, effects that may be related to the reduction of endometrial fibrosis and inflammatory response.
To determine the potential of Tiaoshen Tongluo acupuncture (TTA) at Dingzhongxian (MS5) and right Dingpangxian (MS8) to alleviate post-stroke spasticity (PSS) in stroke rats, by evaluating its influence on neurological function, muscle tightness, and neurotransmitter balance within the context of the nuclear transcription factor E2-related factor 2 (Nrf2)/reactive oxygen species (ROS) signaling pathway.
Randomly distributed among six groups – sham operation, PSS model, drug treatment, non-acupoint acupuncture, TTA therapy, and TTA combined with ML385 – were 90 male SD rats, with 15 in each. Middle cerebral artery occlusion served as the foundational mechanism for the establishment of the PSS model. Rats in the medication group, following the modeling, received a daily dose of baclofen (0.4 mg/kg) by gavage for seven days. For the non-acupoint acupuncture group, rats were needled at a point located 10 mm above the iliac crest and below the affected side's armpit. In contrast, rats in the TTA and TTA+ML385 groups experienced EA stimulation (1 mA, 2 Hz/15 Hz) applied to MS5 and the right MS8, lasting for 10 minutes daily for seven consecutive days. Before the TTA treatment was administered to the TTA+ML385 group of rats, an intraperitoneal injection of ML385, a specific nuclear factor erythroid 2-related factor 2 (Nrf2) inhibitor, was given at a dose of 30 mg/kg. Referring to Zea Longa's methods, the neurological deficit score (0-4 points) of the rats was evaluated, along with the Ashworth scale (MAS) used to assess the quadriceps femoris muscular spasm degree (0-4 points) of the left hindlimb. health resort medical rehabilitation Measurement of the muscular tension of the left quadriceps femoris was achieved via a tension sensor. Correspondingly, an electrophysiological recorder captured the Hoffman (H)-reflex response, alongside the M and H waves of the electromyogram, which were sourced from the muscle located between the metatarsals of the left foot. Immune evolutionary algorithm After staining with 23,5-triphenyltetrazolium chloride (TTC), the infarction volume in the cerebral region was measured. The right cortical infarct area's contents of -aminobutyric acid (GABA), glycine (Gly), glutamic acid (Glu), and aspartic acid (Asp) were determined using high-performance capillary electrophoresis. Further analysis involved fluorescence spectrophotometry to measure 5-hydroxytryptamine (5-HT), dopamine (DA), and norepinephrine (NE). Dihydroethidium staining was subsequently used to detect the ROS levels in the right cerebral cortical infarction tissues. Western blot analysis served to detect the protein expression levels of Nrf2 and heme oxygenase-1 (HO-1) specifically in the infarcted cerebral tissue.
In contrast to the sham-operated group, the neurological deficit score, MAS score, percentage of cerebral infarction volume, Hmax/Mmax ratio, Glu and Asp content, and ROS levels all demonstrated a statistically significant rise.
While (0001) remained unchanged, a significant decline was observed in muscle tone, H-reflex stimulation threshold, GABA, Gly, 5-HT, DA, NE content, cerebral Nrf2, and HO-1 protein expression levels.
Regarding the model group, . Substantially lower neurological deficit scores, MAS scores, cerebral infarction percentages, Hmax/Mmax ratios, Glu, Asp, and ROS levels were observed in the study group compared to the model group.
Increases were observed in muscle tone, the stimulation threshold for eliciting the H-reflex, levels of GABA, Gly, 5-HT, DA, and NE, and the protein expressions of Nrf2 and HO-1, (with reference 0001).

A quantitative proteomics study utilizing Tandem Mass Tags (TMT) will investigate the potential mechanism of acupuncture in regulating qi and alleviating depression, particularly in rats exposed to chronic unpredictable mild stress (CUMS).
The thirty-six male SD rats were divided into three treatment groups, namely control, model, and acupuncture, each group containing twelve rats, through a random allocation procedure. A 21-day CUMS stress period was used to induce the depression model. The rats in the acupuncture group, after the depression model was implemented, underwent a regimen of manual acupuncture stimulation at both Baihui (GV20) and Yintang (GV24).
