ABSTRACT
ObjectiveTo explore the therapeutic mechanism of Faeces Bombycis on diabetic gastroparesis (DGP) rats based on phosphatidylinositol 3-kinase/protein kinase B/mammalian rapamycin target protein (PI3K/Akt/mTOR) signaling pathway. MethodDGP rat model was prepared by random selection of 15 out of 105 rats as blank group. The rats successfully constructed were randomly divided into model group, high-,medium- and low- dose groups (3.2, 1.6, 0.8 g·kg-1) and moxapride group (1.5 mg·kg-1), with 12 rats in each group, and were given gavage for 4 weeks. The gastric emptying rate and random blood glucose were measured. The morphological changes of gastric antrum were observed by hematoxylin-eosin (HE) staining, and the expression of the c-Kit gene was analyzed by immunohistochemistry. The apoptosis of Cajal interstitial cells was observed by in situ end labeling (TUNEL) staining, and the protein expressions of PI3K, phosphorylation(p)-PI3K, Akt, p-Akt, mTOR, and p-mTOR were detected by Western blot. ResultCompared with the blank group, the gastric emptying rate of the model group decreased significantly (P<0.01), and the glandular structure of the gastric antrum was destroyed. The expression of c-Kit decreased (P<0.01), and the apoptosis of Cajal interstitial cells (ICC) increased. Compared with the model group, the gastric emptying rate in the high, middle, and low-dose groups of Faeces Bombycis extract and mosapride group increased significantly (P<0.01). The glandular structure of the gastric antrum became closer, and the apoptosis of ICC decreased. The expression of c-Kit in the high dose group of Faeces Bombycis extract increased significantly. After Western blot testing, compared with the blank group, the protein expression of p-Akt/Akt, p-PI3K/PI3K, and p-mTOR/mTOR in the model group increased. Compared with the model group, the protein expression of p-Akt/Akt in the high dose group of Faeces Bombycis extract decreased (P<0.01), and the protein expression of p-PI3K/PI3K decreased in the middle and low dose groups of Faeces Bombycis extract and mosapride group decreased (P<0.05, P<0.01). The protein expression of p-mTOR/mTOR decreased in the low dose group of Faeces Bombycis extract (P<0.05). In terms of random blood glucose, compared with the blank group, the random blood glucose in the model group increased significantly (P<0.01), and compared with the model group, the random blood glucose in the high and middle dose groups of Faeces Bombycis extract decreased significantly (P<0.05). Compared with mosapride group, the protein expression of p-Akt/Akt decreased in the high dose group of Faeces Bombycis extract (P<0.05), and the protein expression of p-PI3K/PI3K increased in the high, middle, and low dose groups of Faeces Bombycis extract (P<0.05, P<0.01). ConclusionFaeces Bombycis extract can increase gastric emptying rate, reduce ICC apoptosis, and lower random blood glucose in DGP rats. The high dose group of Faeces Bombycis extract has a significant effect on inhibiting ICC apoptosis, and its mechanism may be related to the regulation of the PI3K/Akt/mTOR signaling pathway.
ABSTRACT
AIM:To establish a model of meibomian gland dysfunction in rats induced by eyeliner tattoo and investigate its potential mechanisms.METHODS:A total of 40 SD rats were selected, with 30 randomly chosen to have eyeliner tattoo applied their right eyes and designated as the eyeliner group. The remaining 10 rats were not given any treatment and served as the normal group. The corneal morphology of both groups was observed using a slit lamp at 1, 2, and 4 wk after establishment, and the tear film break-up time(BUT), Schirmer I test(SIt), corneal fluorescein staining score, and corneal irregularity score were calculated. The corneal Placido rings were examined using an ocular surface analyzer, and the corneal tissue structures of both groups were observed under a confocal microscope. After 4 wk and completion of clinical indicator recording, the eyeballs and upper and lower eyelid tissues were taken for pathological examination. The meibomian gland structures were observed through HE staining, the conjunctival goblet cells were observed using PAS staining, and the lipid droplets were observed with ORO staining.RESULTS:The slit lamp examination results showed that the eyeliner group rats exhibited in situ black pigmentation in the eyelids, with no eyelid deformation or scarring. The corneal epithelium was rough, with positive fluorescein staining, presenting as spotty staining that worsened over time. Compared with the normal group, the BUT was significantly shortened, tear secretion volume was significantly decreased, and the corneal fluorescein staining score and corneal irregularity score were significantly increased at 1, 2, and 4 wk after modeling in the eyeliner group(all P<0.01). The corneal confocal microscopy results showed a decrease in corneal epithelial cells in the eyeliner group, with the appearance of abnormally bright cells, and inflammatory cell infiltration visible in the stromal layer. The ORO staining results revealed a decrease in lipid droplets in the eyeliner group, showing a downward trend with increasing observation time. The HE staining results showed that pigment blocked the meibomian gland openings in the eyeliner group, and the density of meibomian gland acini showed a downward trend over time. The PAS staining results showed a decreasing trend in the number of PAS-positive cells in the eyeliner group.CONCLUSION:Eyeliner tattoo can induce meibomian gland dysfunction, and the blockage of meibomian gland openings caused by the pigment particles used may be an important cause of meibomian gland dysfunction.

ABSTRACT
【Objective】 To explore the correlation between CSAG1 expression and the prognosis and tumor-infiltrating lymphocytes in renal clear cell carcinoma (RCCC), and to predict the survival and tumor progression. 【Methods】 The gene expression profiles and clinical information of CSAG1 were downloaded from the Cancer Genome Atlas (TCGA). Based on the differential mRNA expression, GO annotation and KEGG pathway analysis were performed. The relationship between CSAG1 and tumor immune infiltration was assessed with Tumor Immunoassay Resource (Timer 2.0) database. The mRNA expression of CSAG1 in human RCCC specimens was validated with qRT-PCR. 【Results】 CSAG1 expression was significantly higher in RCCC tissues than in normal tissues (P<0.05). The qRT-PCR results revealed that the mRNA level of CSAG1 was consistent with that predicted by bioinformatic analysis. The KEGG analysis and GO annotation indicated high GSAG1 expression in RCCC was related to transmembrane transport, tricarboxylic acid cycle and lysosome. CSAG1 expression was positively related to the infiltration of pDC, aDC, CD8+ T cells, cytotoxic cells, TFH, TH1 cells, Tem, NK CD56dm cells, Treg and T cells, but negatively correlated with macrophage infiltration. 【Conclusion】 CSAG1 may be associated with poor prognosis of RCCC and become a potential immunotherapy target.
ABSTRACT
Objective To establish an efficient method for isolating migrasomes from RAW264.7 macrophages and identifying these isolated migrasomes. Methods Scanning electron microscopy was used to observe the morphological characteristics of migrasomes produced by RAW264.7 cells. A 0.45 μm filter was employed for reverse filtration and elution to isolate the migrasomes. The morphological characteristics of the migrasomes were then observed using transmission electron microscopy. Western blot analysis was performed to determine the expression of characteristic markers of the migrasomes. The RNA carried by the migrasomes was analysed by using LabChip bioanalyzer. Results Scanning electron microscopy revealed that the migrasomes, with membranous structures, were attached to the tip or bifurcation of the retraction fiber formed in the tail of RAW264.7 cells. Transmission electron microscopy showed that the isolated migrasomes had a typical oval vesicle-like structure with wrinkled membrane surfaces. Western blot analysis confirmed the expression of the characteristic markers phosphatidylinositol glycan anchor biosynthesis class K (PIGK), epidermal growth factor domain-specific O-linked N-acetylglucosamine transferase (EOGT) and tetraspanin 4 (TSPAN4) in the migrasomes, while the EV (extracellular vesicle) markers tumor susceptibility gene 101 (TSG101) and Arabidopsis homolog of apoptosis-linked gene 2-interacting protein X (ALIX) were not detected. Furthermore, the isolated migrasomes were found to be rich in small RNA, which were approximately 25-200 nt in length. Conclusion A method for the extraction of well-structured and high quality migrasomes from macrophages is established.

Glioblastoma(GBM)originates from glial cells,and complete surgical resection followed by radiotherapy and chemotherapy is the current standard treatment.However,gliomas are subjected to not only accelerated cell death after radiotherapy and chemotherapy but also cellular senescence.Senescent cells produce a senescence-associated secretory phenotype(SASP),which has a dual effect on the tumor microenvironment.The"one-two punch"strategy of specifically eliminating senescent cells and inhibiting SASP-derived secretions provides a new direction for tumor therapy.In this article,we review the mechanisms that mediate tumor cellular senescence and SASP,the elimina-tion of senescent cells by senolytics for SASP inhibition,and the current situation of the"one-two punch"strategy for the treatment of glioma.
ABSTRACT
Objective:To explore how electrical stimulation of the sciatic nerve affects learning and memory in cases of chronic cerebral hypoperfusion and its mechanism.Methods:Thirty-two Sprague-Dawley rats were randomly divided into a normal group, a sham-operation group, a model group and a stimulation group, each of 8. In the model and stimulation groups a chronic cerebral hypoperfusion model was established using the modified 2-VO method. The stimulation group then received electrical stimulation of the sciatic nerve for 4 weeks. Afterward all of the rats′ learning and memory were tested using the Morris water maze. HE staining and immunohistochemistry were used to observe any morphological change in the hippocampus and the expression of neuron-specific enolase (NSE) and vascular endothelial growth factor (VEGF).Results:The model and stimulation groups demonstrated significantly longer escape latency, fewer platform crossing times and shorter target quadrant times than the normal and sham-ope-ration groups before the intervention. All of these indicators had improved after the intervention. According to the HE staining, neuronal damage in the hippocampus was aggravated significantly in the model group compared with the normal and sham-operation groups, while the degree of damage was reduced in the stimulation group. Moreover, the immunohistochemistry results suggested that the expressions of NSE and VEGF were reduced significantly in the model group compared with the normal and sham-operation groups, while in the stimulation group they had increased significantly compared with the model group.Conclusions:Electrical stimulation of the sciatic nerve can improve learning and memory in cases of chronic cerebral hypoperfusion, at least in rats. It is probably related to the increased expression of VEGF in the hippocampus.
ABSTRACT
Male reproductive infections are known to shape the immunological homeostasis of the testes, leading to male infertility. However, the specific pathogenesis of these changes remains poorly understood. Exosomes released in the inflammatory microenvironment are important in communication between the local microenvironment and recipient cells. Here, we aim to identify the immunomodulatory properties of inflammatory testes-derived exosomes (IT-exos) and explore their underlying mechanisms in orchitis. IT-exos were isolated using a uropathogenic Escherichia coli (UPEC)-induced orchitis model and confirmed that IT-exos promoted proinflammatory M1 activation with increasing expression of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) in vitro. We further used small RNA sequencing to identify the differential miRNA profiles in exosomes and primary testicular macrophages (TMs) from normal and UPEC-infected testes, respectively, and identified that miR-155-5p was highly enriched in IT-exos and TMs from inflammatory testes. Further study of bone marrow derived macrophages (BMDMs) transfected with miR-155-5p mimic showed that macrophages polarized to proinflammatory phenotype. In addition, the mice that were administrated IT-exos showed remarkable activation of TM1-like macrophages; however, IT-exos with silencing miR-155-5p showed a decrease in proinflammatory responses. Overall, we demonstrate that miR-155-5p delivered by IT-exos plays an important role in the activation of TM1 in UPEC-induced orchitis. Our study provides a new perspective on the immunological mechanisms underlying inflammation-related male infertility.

ObjectiveTo explore the biological mechanism of drought improving the quality of Rhizoma Atractylodis Chinensis and establish a new method for the production of high-quality medicinal materials. MethodThe fresh roots of Atractylodes chinensis were soaked in 0 (control), 5%, 10%, and 20% PEG-6000 solutions. The changes in reactive oxygen species (ROS) level, antioxidant enzyme activity, activities of key enzymes in primary metabolism and secondary metabolism, and content of secondary metabolites were compared. ResultCompared with the control group, the treatment with 20% PEG for 2 days elevated the levels of superoxide anion radicals (O2-·), hydrogen peroxide (H2O2), and malondialdehyde (MDA) by 172.5%, 56.9%, and 14.7%, respectively. The treatment did not change the activity of superoxide dismutase (SOD), reduced the peroxidase (POD) activity, and increased the catalase (CAT) activity by 10.8%. It increased the activities of 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR), phosphoenolpyruvate carboxylase (PEPC), and acetyl-CoA carboxylase (ACC) by 49.9%, 12.1%, and 19.0%, respectively. Furthermore, the content of atractylodin, β-eudesmol, atractylone, and atractylenolide Ⅱ was increased by 51.0%, 36.9%, 47.1%, and 91.5%, respectively. The simulated drought stress can cause the burst of ROS in the fresh roots of A. chinensis, induce the physiological state of plants under drought, change the antioxidant system, and promote the massive synthesis of secondary metabolites in a short time. ConclusionPEG-6000-simulated drought stress can greatly improve the quality of A. chinensis in cultivation.
ABSTRACT
AIM: To study the effects of long-term use of clozapine on tear film stability and ocular surface tissue structure.METHODS: Case-control study was conducted on 45 patients(group 1)who were diagnosed with schizophrenia and treated with clozapine for 3.45±0.72a between March 2021 and December 2021. Another 45 healthy subjects(group 2)served as controls, whose demographic characteristics were similar to those of group 1. Patients' dry eye symptoms were investigated using OSDI questionnaire, tear secretion was detected by the Schirmer I test, ocular surface damage was assessed by the ocular surface staining score, and comprehensive ophthalmic examination was performed on all patients through LipiView ocular surface interferometer, ocular surface integrated analyzer, corneal confocal microscope and slit lamp photographic system.RESULTS: Slit-lamp photography showed diffuse grayish-white spot-like opacification in the corneal stroma of group 1, accompanied by brown star-like opacification in the center of the anterior capsule of the lens. OSDI scores were 38.00(31.50, 48.50)and 15.00(9.00, 19.50)in the two groups respectively. Schirmer test showed that the group 1 was 5.27±2.18mm/5min, while group 2 was 15.62±3.05mm/5min. Corneal fluorescein staining score: 4.00(2.50, 5.00)for group 1 and 1.00(0.00, 1.50)for group 2. The lissamine green staining score for the conjunctiva was 9.00(6.50, 10.00)and 3.00(2.00, 3.50)for the two groups, respectively. LipiView detected lipid layer thickness(LLT), suggesting that the results of group 1 and group 2 were similar, respectively 75.91±15.51 and 77.24±12.11nm; and the results were similar for the lid gland deficiency score, with 1.37±0.26 and 1.29±0.31 points, respectively. The mean tear meniscus height in group 1 was 0.13±0.06mm, which was lower than 0.23±0.04mm of group 2. Non-invasive breakup time(NIBUT)was 6.04±2.62 and 11.4±2.74s in group 1 and group 2 respectively. OSDI score, Schirmer Ⅰ test, ocular surface staining score, tear meniscus height and NIBUT were significantly different between the two groups(P<0.05). Confocal corneal microscopy suggested decreased corneal nerve fiber density with stromal layer inflammatory cell infiltration and pigmentation in group 1.CONCLUSION: The antipsychotic drug clozapine can induce dry eye with a range of ocular surface injuries such as corneal pigmentation, and patients who taking such drugs should be routinely examined by an ophthalmologist.
ABSTRACT
Acute kidney injury is a common complication after liver transplantation, which severely affects clinical prognosis of liver transplant recipients. Multiple factors before, during and after liver transplantation may cause kidney injury. If not properly treated, it may progress into chronic kidney diseases, which significantly increases postoperative fatality and negatively affects clinical efficacy of liver transplantation. Therefore, prevention, diagnosis and treatment of acute kidney injury after liver transplantation is a hot topic for clinicians. In this article, the definition, diagnosis, risk factors, prevention and treatment of acute kidney injury after liver transplantation were reviewed, and potential risk factors and related therapeutic strategies during different stages of acute kidney injury after liver transplantation were analyzed, aiming to lower the risk of acute kidney injury after liver transplantation and further improve clinical prognosis of liver transplant recipients by optimizing treatment regimens.
ABSTRACT
Objective:To explore the effect of combining hyperbaric oxygen (HBO) therapy with cognition training for persons with vascular cognitive impairment (VCI).Methods:Forty-two persons with VCI were randomly divided into a control group of 19 and a research group of 23. In addition to basic treatment, the control group was given hyperbaric oxygen therapy once a day, 5 days per week for 4 weeks, while the research group received cognition training along with the hyperbaric oxygen therapy. Each person′s cognition was assessed using the Simple Mental Status Scale (MMSE) before and after the four-week treatment. Meanwhile, 3ml of venous blood was collected before eating in the morning to test the plasma levels of Klotho protein and homocysteine using enzyme-linked immunosorbent assays.Results:After the treatment the average MMSE score had improved significantly in both group, with the improvement in the research group′s average significantly greater than that in the control group. The average plasma levels of Klotho protein and homocysteine had also improved significantly more in the research group. In the control group, the only significant improvement was in the average homocysteine level.Conclusions:Hyperbaric oxygen therapy can be an effective supplement to cognition training for persons with vascular cognitive impairment.
ABSTRACT
Objective To investigate the expression of MEX3A in colorectal cancer (CRC), and to explore the effect and mechanism of MEX3A on the proliferation and migration of colorectal cancer cells. Methods Totally 327 cases of data(41 normal tissues and 286 tumor tissues) were obtained from TCGA database, and 104 cases of clinical samples (77 cases tissues and 27 paracancerous tissues) were collected for immunohistochemistry, then analysed the differences in MEX3A expression between CRC tissues and normal tissues. Western blotting and immunofluorescence staining were used to evaluate the differential expression of MEX3A in CRC cell lines. CL187 cells were selected as the follow-up research vector. Small interfering RNA of MEX3A(siMEX3A) was transfected into CL187 cells to inhibit the expression of MEX3A. The proliferation and migration of CL187 cells were measured by MTT, colony formation assay and Transwell assay. The expression of PI3K, p-PI3K, Akt and p-Akt were detected by Western blotting. Results TCGA database, immunohistochemistry and Western blotting analysis showed that MEX3A was highly expressed in colorectal cancer. The result of immunofluorescence staining showed that MEX3A was concentrated in the cytoplasm and the nucleus. In MTT, colony formation assay and Transwell assay, the proliferation and migration ability of CL187 cells in siMEX3A group decreased significantly than those in control group (P<0.05). Western blotting result showed that the expression of p-PI3K and p-Akt in siMEX3A group down-regulated significantly (P<0.05), and the inhibition of proliferation and migration ability of CL187 cells induced by siMEX3A group could be reversed by 740 Y-P via activating the PI3K/Akt signaling pathway. Conclusion MEX3A is highly expressed in colorectal cancer and promotes the proliferation and migration of CRC cells via PI3K/Akt signaling pathway.
ABSTRACT
Objective:To explore the clinical features, surgical treatments and treatment effects of children with skull defect.Methods:Sixty children with skull defect, admitted to our hospital from January 2010 to December 2020, were chosen in our study. These children were divided into encephalocele group ( n=28) and non-encephalocele group ( n=32) according to the imaging results (whether brain tissues were 1.5 cm higher than the bone window plane or not). The time and area of skull defect were compared between the two groups. Titanium mesh or polyether ether ketone material were used to repair the skull defect; 24 children without nerve fiber bundle distribution from encephalocele group underwent resection of the encephalocele tissues additionally. All children were followed up for 3-10 years in the outpatient department, and the prognoses of children from the two groups were evaluated by Glasgow Outcome Scale (GOS) one year after surgery. Results:As compared with the non-encephalocele group, children in the encephalocele group had significantly younger age accepted skull removal, significantly longer skull defect course, significantly higher incidence of epilepsy, significantly more common secondary changes in the brain tissues around the defect, but statistically smaller skull defect area ( P<0.05). There was no bleeding, severe edema, wound infection or cerebrospinal fluid leakage after surgery in both groups, and primary healing was achieved. In the encephalocele group, 16 children were complicated with epilepsy; 10 got complete seizure control, and 6 got seizure improvement. In the non-encephalocele group, 8 children were complicated with epilepsy; 6 got complete seizure control, and 2 got seizure improvement. Postoperative follow-up showed that GOS scores in the non-encephalocele group were significantly higher than those in encephalocele group ( P<0.05). Conclusion:As ompared with skull defect children without encephalocele, skull defect children with encephalocele have earlier defect age, longer course of disease, higher incidences of ventricular perforation malformation and epilepsy, and a relatively poorer prognosis.
ABSTRACT
Objective:To explore the value of blood lipids, serum interleukin-6 (IL-6) and thyroid-stimulating hormone (TSH) detection in patients with differentiated thyroid cancer.Methods:From Mar. 2016 to Oct. 2021, 120 cases of DTC were admitted to the DTC group, 138 patients with benign thyroid nodules were included in the benign group, and 100 healthy people undergoing the physical examination in our hospital during the same period. were enrolled in the control group. Triglyceride (TG) , total cholesterol (TC) , high density liptein cholesterol (HDL-C) , low density lipoprotein (LDL-C) , IL-6, and TSH were compared between groups, and statistically significant indexes were included for multivariate analysis of the occurrence of DTC. The sensitivity, specificity and optimal cut-off value were analyzed, and their relationship with the clinicopathological characteristics of DTC patients was analyzed.Results:Serum TSH and IL-6 levels from high to low were malignant group, benign group and control group, and HDL-C levels from high to low were control group, benign group and malignant group ( P<0.05) . There was no significant difference in the levels of TC, TG or LDL-C ( P>0.05) . Multivariate Llogistics regression analysis indicated that TSH and IL-6 may be risk factors for the occurrence of differentiated thyroid cancer (all OR>1, P<0.05) . HDL-C may be a protective factor for the occurrence of differentiated thyroid cancer ( OR<1, P<0.05) . The ROC curve was drawn to determine the optimal cut-off value of TSH for the diagnosis of differentiated thyroid cancer, AUC: 0.985, sensitivity was 93.25%, specificity was 96.34%, 95% CI: 0.949-1.000 ( P<0.001) ; the best cut-off value of IL-6 for the diagnosis of differentiated thyroid cancer was 48.96 ng/L, AUC: 0.980, sensitivity was 96.98%, the specificity was 91.53%, 95%CI: 0.956-1.000 ( P<0.05) ; the best cut-off value of HDL-C for the diagnosis of differentiated thyroid cancer was 1.441 mmol/L, AUC: 0.0.691, the sensitivity was 85.10%, the specificity was 48.06%, 95%CI: 0.563-0.812 ( P<0.05) . The serum levels of TSH and IL-6 in patients with lymph node metastasis were significantly higher than those in patients without lymph node metastasis, and the level of HDL-C was significantly lower than those in patients without lymph node metastasis ( P<0.05) . TNM staging The serum levels of TSH and IL-6 in patients with stage III and IV were significantly higher than those in patients with stage I and II, and HDL-C was significantly lower than that in patients with stage I and II ( P<0.05) . Conclusions:Serum IL-6, TSH and HDL-C are closely related to the occurrence of differentiated thyroid cancer. The detection of serum IL-6, TSH and HDL-C is helpful for the differentiation of benign and malignant thyroid nodules. The presence or absence of lymph node metastasis in patients with differentiated thyroid cancer is related to TNM staging, and the detection value is high.
ABSTRACT
Objective:To investigate the relationship between number of daily steps and insomnia in patients with chronic insomnia using "WeChat Sports" program.Methods:A total of 190 patients with insomnia who received treatment in Department of Neurology, Zhejiang University of Traditional Chinese Medicine Affiliated Wenzhou Hospital between October 2017 and October 2019. General data (age, sex, body mass index, history of smoking and alcohol use) and the number of daily steps recorded by "WeChat Sports" program were collected. Patients whose average number of daily steps was greater than 7500 were assigned to the sufficient exercise group ( n = 68), and the remaining patients were assigned to the insufficient exercise group ( n = 122). Patient symptoms were assessed using the Pittsburgh Sleep Quality Index (PSQI), The Patient Health Questionnaire-9, and generalized Anxiety Disorder scale-7. Scale evaluation and data collection were performed by two trained investigators. Data were compared between the two groups. The correlation between average number of daily steps and each scale score was analyzed. Results:Total PSQI score in the sufficient exercise group was significantly lower than that in the insufficient exercise group [(12.94 ± 3.14) points vs. (14.93 ± 2.99) points, t = 4.31, P < 0.001]. Scores of subjective sleep quality, sleep latency, habitual sleep efficiency, use of sleep medication, and daytime dysfunction were significantly lower in the sufficient exercise group than those in the insufficient exercise group ( P = 0.011, 0.008, 0.025, 0.039, 0.006). The Patient Health Questionnaire-9 and Generalized Anxiety Disorder Scale-7 scores in the sufficient exercise group were significantly lower than those in the insufficient exercise group ( P = 0.011, P = 0.002). The average number of daily steps was significantly negatively correlated with total PSQI score, Patient Health Questionnaire-9 score, Generalized Anxiety Disorder Scale-7 score, and score of each PSQI component (subjective sleep quality, sleep latency, habitual sleep efficiency, and daytime dysfunction) ( r = -0.29, -0.16, -0.19, -0.24, -0.15, -0.18, -0.23). Conclusion:Insomnia patients with insufficient daily exercise have more serious insomnia and emotional symptoms than those with sufficient daily exercise. Daily average exercise is correlated with the severity of insomnia and emotional symptom.
ABSTRACT
Objective:To investigate the effect of combining aerobic exercise with hyperbaric oxygen therapy on the cognition and oxidative stress of patients with post-stroke cognitive impairment (PSCI).Methods:Forty-five PSCI patients were divided randomly into a hyperbaric oxygen therapy (HBO) group (of 21) and a combination group (of 24). Both groups received HBO therapy, but the combination group also performed 30min of aerobic exercise using a cycle ergometer 5 times a week for 8 weeks. The HBO therapy involved 20min for pressurization, 20min of decompression, 60min of pressurized oxygen inhalation and 10min of air inhalation. The treatment pressure was 0.2MPa (2.0ATA). Before and after the intervention, cognitive functioning was measured using the mini-mental state examination (MMSE) and the Montreal cognitive assement (MoCA). The Barthel index quantified ability in the activities of daily living. Serum glutathione (GSH) and malondialdehyde (MDA) were measured spectrophotometrically.Results:The average MMSE scores of both groups had improved significantly after the treatment, with significantly better improvement in the combination group. After the treatment, the average MoCA score of the combination group had improved significantly while that of the HBO group had not. The average Barthel index scores of both groups improved significantly and there was no significant difference between them after the treatment. The average serum GSH increased after the treatment in the combination group, and the increase was weakly positively correlated with the increase in MMSE scores. The average MDA content of the HBO group decreased after the treatment, and the decrease was positively correlated to the increase in the MMSE scores, but again weakly.Conclusions:Aerobic exercise combined with hyperbaric oxygen therapy can effectively improve cognition among PSCI patients. Increases in serum GSH and decreases in serum MDA are weakly positively correlated with cognitive functioning.
