Objective:To explore the effects of mindfulness-based decompression therapy on fear of disease progression, quality of life and sleep quality in patients with acute ischemic stroke, in order to provide intervention measures to alleviate fear of the disease progression degree and improve sleep and quality of life in patients with acute ischemic stroke.Methods:This study was a randomized controlled study. Using the convenience sampling method, 98 patients with acute ischemic stroke who attended the Department of Neurology at the Third Hospital of Hebei Medical University from November 2021 to September 2022 were selected for the study, and the study population was divided into experimental group ( n=49) and control group ( n=49) using the random number table method. The control group received conventional care, and the experimental group received mindfulness-based stress reduction therapy for 8 weeks in addition to conventional care. Compared the scores of the Fear of Progression Questionnaire-Short Form (FoP-Q-SF), Stroke-Specific Quality of Life Scale (SS-QOL), and Pittsburgh Sleep Quality Index (PSQI) between the two groups of patients before and after intervention using two independent sample t-tests, and further compared the score spread of each scale before and after intervention between the two groups of patients using Mann-Whitney U test. Results:In the experimental group, 4 cases fell off and 3 cases had imperfect questionnaire information, while in the control group, 2 cases fell off and 5 cases had imperfect questionnaire information. Finally, 42 cases were included in each group. The 23 males and 19 females in the control group aged (48.31 ± 7.61) years old, while 25 males and 17 females in the experimental group aged (50.19 ± 8.64) years old. There was no significant difference in FoP-Q-SF, SS-QOL and PSQI scores between the two groups before intervention (all P>0.05). After intervention, the scores of FoP-Q-SF and PSQI in the experimental group (35.79 ± 7.04, 7.19 ± 2.58) were lower than those in the control group (38.52 ± 4.02, 9.45 ± 2.28), while the SS-QOL score (200.36 ± 21.75) was higher than that in the control group (185.41 ± 15.90), the differences were statistically significant ( t=2.19, -4.26, 3.60, all P<0.05). After intervention, the scores of FoP-Q-SF and PSQI in the experimental group were lower than those before intervention (39.69 ± 4.15, 10.00 ± 2.85), while the SS-QOL score was higher than that before intervention (176.93 ± 23.54), the differences were statistically significant ( t=4.80, 10.45, -11.43, all P<0.05). The score spreads of FoP-Q-SF, SS-QOL, and PSQI in the experimental group before and after intervention were 1.00 (0.00, 9.25), 20.00 (12.75, 32.75), 3 (1, 4), which were higher than 1.00 (-1.25, 2.00), 5.50 (1.00, 10.25), 0 (-1, 2) in the control group, the differences were statistically significant ( Z=-2.30, -5.74, -5.53, all P<0.05). Conclusions:Mindfulness-based decompression therapy can effectively relieve the fear of disease progression and improve the quality of sleep and life in patients with acute ischemic stroke.
Résumé
Liver fibrosis is the leading cause of the morbidity and mortality of liver diseases worldwide and has become one of the key issues in the research on chronic liver diseases among domestic and foreign scholars. An increasing amount of evidence has shown that gut microbiota dysbiosis plays a crucial role in the development and progression of liver fibrosis, and improvement of gut microbiota dysbiosis has become a new target for anti-fibrotic treatment. At present, traditional Chinese medicine has attracted much attention in improving gut microbiota. Studies have shown that "harmonizing liver and spleen" plays an important role in reducing fibrosis degree and delaying the progression of liver fibrosis. Therefore, based on the theory of "harmonizing liver and spleen", the achievements in liver-gut axis and gut microbiota by modern molecular biological techniques can provide a theoretical basis for the treatment of liver fibrosis from "harmonizing liver and spleen" in clinical practice, as well as new directions and ideas for anti-fibrotic treatment with traditional Chinese medicine.

ObjectiveTo observe the effect of ginsenoside Rg1 (G-Rg1) on the biological activity of cryopreserved Schwann cells (SCs) of the rat sciatic nerve and explore the feasibility of G-Rg1 in reducing the cryopreservation-induced injury in SCs. MethodBilateral sciatic nerves of SD rats were randomly divided into a fresh group, a blank group, and five G-Rg1 groups of different doses (1×10-7, 1×10-6, 1×10-5, 1×10-4, and 1×10-3 mol·L-1). The nerves in the blank group and the G-Rg1 groups were preserved in liquid nitrogen solutions containing 0, 1×10-7, 1×10-6, 1×10-5, 1×10-4, and 1×10-3 mol·L-1 G-Rg1 for four weeks. The apoptosis of SCs was detected by TdT-mediated dUTP-biotin nick end labeling (TUNEL)/S100 immunofluorescence staining. The expression of cysteinyl aspartate-specific protease (Caspase)-9, Caspase-3, major histocompatibility complex (MHC)-Ⅰ, and MHC-Ⅱ was detected by Western blot. Subsequently, all nerves were cultured in the incubator at 37 ℃ with 5% CO2 for 7 days. The expression of glial cell line-derived neurotrophic factor (GDNF) and nerve growth factor (NGF) was detected by Western blot. In addition, the above cryopreserved nerves in the blank group and the 1×10-6, 1×10-5, and 1×10-4 mol·L-1 G-Rg1 groups were transplanted to the Wistar rats by allografting (blank transplantation group and the 1×10-6, 1×10-5, and 1×10-4 mol·L-1 G-Rg1 transplantation groups), and fresh sciatic nerve allograft and isograft control group were set up. Sixteen weeks after transplantation, compound muscle action potential (CMAP) and nerve conduction velocity (NCV) were measured by electrophysiology. Nerve filament (NF)200 immunofluorescence staining, transmission electron microscopy, and toluidine blue staining were used to analyze the histology of the regenerated nerves. ResultCompared with the fresh group, the blank group and the G-Rg1 groups showed increased expression of Caspase-9, Caspase-3, and the apoptosis of SCs (P<0.05,P<0.01) and decreased expression of GDNF, NGF, MHC-Ⅰ, and MHC-Ⅱ (P<0.01). Compared with the results in the blank group, the expression of Caspase-9 and Caspase-3 decreased in the 1×10-7, 1×10-6, 1×10-5,1×10-4 mol·L-1 G-Rg1 groups (P<0.01), and the apoptosis of SCs was reduced in the 1×10-7-1×10-4 mol·L-1 G-Rg1 groups(P<0.05,P<0.01) and increased in the 1×10-3 mol·L-1 group (P<0.05), while the expression of GDNF and NGF increased in the 1×10-7, 1×10-6, 1×10-5,1×10-4 mol·L-1 G-Rg1 groups and decreased in the 1×10-3 mol·L-1 group (P<0.05). There was no statistical significance in the expression of MHC-Ⅰ and MHC-Ⅱ between the blank group and the G-Rg1 groups. Compared with the 1×10-7 mol·L-1 and 1×10-3 mol·L-1 G-Rg1 groups, the 1×10-6 1×10-5, 1×10-4 mol·L-1 G-Rg1 groups showed decreased expression of Caspase-3 and the apoptosis of SCs (P<0.05,P<0.01) and increased expression of GDNF and NGF (P<0.05,P<0.01). There was no statistical significance in MHC-Ⅰ and MHC-Ⅱ expression among G-Rg1 groups. Sixteen weeks after transplantation, compared with the isograft group, the blank transplantation group and the G-Rg1 transplantation groups showed decreased CMAP, NCV, myelin sheath thickness, and number of myelinated nerve fibers (P<0.01), and the 1×10-6 and 1×10-4 mol·L-1 G-Rg1 transplantation groups showed decreased NF200 (P<0.01). Compared with the allograft group, the blank transplantation group and the G-Rg1 transplantation groups showed increased CMAP, NCV, NF200, myelin sheath thickness, and number of myelinated nerve fibers (P<0.05,P<0.01). Compared with the blank transplantation group, the G-Rg1 transplantation groups showed increased CMAP, NCV, NF200, myelin sheath thickness, and number of myelinated nerve fibers (P<0.05,P<0.01). Among all groups of G-Rg1 transplantation, each index of the 1×10-5 mol·L-1 G-Rg1 transplantation group was superior to that of the 1×10-4 and 1×10-6 mol·L-1 G-Rg1 transplantation group (P<0.05). ConclusionG-Rg1 at a certain centration can maintain the biological activity of cryopreserved SCs of rat sciatic nerve, alleviate the cryopreservation-induced injury of rat sciatic nerve, and promote nerve regeneration after allograft.

OBJECTIVE:To study the impacts of Zishenyutai pills on the ovarian tissue oxidative damage and Nrf2 protein ex-pression in rats exposed by electromagnetic radiation (EMR). METHODS:Accordiny to their weight,30 SD rats were randomly divided into normal group,radiated group and radiated-treated group with 10 rats in each group. Normal group were not radiated, and other 2 groups were exposed by 900 MHz radiation for 4 h every day;radiated-treated group was given Zishenyutai pills sus-pension [0.25 g intragstrically(medicinal materials)/ml] after radiation;normal group and radiated group were given constant vol-ume of normal saline intragastrically for consecutive 20 d. The rats were killed when they were at the estrum. The Nrf2 proteins ex-pression of ovary were detected by immunohistochemical method,the content of ovary MDA(malondialdehyde),and activity of to-tal superoxide dismutase (T-SOD) and superoxide dismutase (GSH-Px) were detected by biochemical method. RESULTS:Com-pared with the rats in normal group,the Nrf2 protein expression was higher in the rats of the radiated group;the content of ovary MDA was higher and activity of ovary T-SOD and GSH-Px were lower significantly(P0.05),the content of ovary MDA was lower and activity of ovary T-SOD and GSH-Px were higher significantly (P<0.05). CONCLUSIONS:Zish-enyutai pills can prevent and cure ovary tissue oxidative injury induced by 900 MHz radiation,but have no effect on the expression of Nrf2 protein.
