RESUMO

OBJECTIVE: To investigate the effects of acupuncture on JNK pathway and autophagy level in rats with intracerebral hemorrhage (ICH) and explore the partial mechanism of acupuncture against ICH. METHODS: SD rats were randomly divided into blank group, model group and acupuncture group. Each group was divided into Day 1, Day 3 and Day 7 subgroups respectively, with 5 rats in each group. The autologous blood injection was adopted to duplicate rat model of ICH. In the acupuncture group, the needle was inserted from "Baihui" (GV20) towards "Qubin" (GB7) on the affected side, stimulating for 30 min each time, once daily; the same acupuncture technique was opera-ted in each subgroup for 1, 3 and 7 days, separately. Using Bederson scale, the neurological deficit was evaluated in each group. Western blot was adopted to detect the protein expression levels of Beclin1, LC3Ⅰ/Ⅱ, phosphorylated c-Jun amino-terminal kinase (p-JNK) and the phosphorylated (p)-c-Jun around hematoma lesion of the brain tissue of rats in each group. RESULTS: After treatment, the neurological deficit score of rats in the model group was higher than that of the blank group at each time point (P<0.05), and the score of the acupuncture group started declining since the 3rd day of treatment when compared with the model group (P<0.05). At each time point, compared with the blank group, the protein expression levels of LC3Ⅰ/Ⅱ, Beclin1, p-c-Jun and p-JNK was increased (P<0.01). Compared with the model group, the protein expression level of LC3Ⅰ/Ⅱ was reduced (P<0.05); the protein expression levels of Beclin1, p-c-Jun and p-JNK was increased (P<0.05, P<0.01) on day 3 and 7 in the acupuncture group. CONCLUSION: Acupuncture can activate the JNK pathway in the brain tissue of rats with ICH and increase the level of autophagy, thereby improving the neurological function of the rats with ICH.

RESUMO

Intracerebral haemorrhage (ICH) can be a catastrophic event; even if the initial stages of the pathology were well-managed, a number of patients experience varied residual neurological deficits following the insult. Ferroptosis is a recently identified type of cell demise which is tightly linked to the neurological impairment associated with ICH. In the current work, the prophylactic impact of scalp acupuncture (SA) therapy on autologous blood injection murine models of ICH was investigated in order to establish whether SA could mitigate the secondary damage arising following ICH by moderating ferroptosis. The pathophysiological mechanisms associated with this process were also explored. Ludmila Belayev tests were utilised for the characterisation of neurological damage. Haematoxylin-eosin staining was employed in order to determine the cerebral impact of the induced ICH. Malondialdehyde (MDA) and iron titres in peri-haemorrhagic cerebral tissues were appraised using purchased assay kits. Transmission electron microscopy delineated mitochondrial appearances within nerve cell bodies from the area of haemorrhage. Western blotting techniques were utilised to assay the degree of protein expression of NeuN, sequestosome 1 (p62), nuclear factor erythroid 2-related factor 2 (Nrf2), Kelch-like ECH-associated protein 1 (Keap1), glutathione peroxidase 4 (GPX4) and ferritin heavy chain 1 (FTH1). The frequencies of Nrf2, GPX4 and FTH1 positive cells, respectively, were documented with immunohistochemical staining. The results demonstrated that therapy with SA after ICH mitigated MDA and iron sequestration, diminished the appearance of contracted mitochondria with increased outer mitochondrial membrane diameter within the nerve cell bodies, and suppressed neuronal ferroptosis. The pathways responsible for these effects may encompass amplified p62, Nrf2, GPX4 and FTH1 expression, together with decreased Keap1 expression. Application of SA reduced identified neurobehavioural abnormalities after ICH; no disparities were observed between the consequences of SA therapy and deferoxamine delivery. It can be surmised that intervention with SA enhanced recovery after ICH by triggering the antioxidant pathway, p62/Keap1/Nrf2, and causing FTH1 and GPX4 upregulation, factors that participate in diminishing excess iron and thus in mitigating lipid peroxidation insults arising from ferroptosis following ICH.

RESUMO

Acupuncture is widely used in the treatment of cerebral hemorrhage, and it improves outcomes in experimental animal models and patients. However, the mechanisms underlying the effectiveness of acupuncture treatment for cerebral hemorrhage are still unclear. In this study, a model of intracerebral hemorrhage was produced by injecting 50 µL autologous blood into the caudate nucleus in Wistar rats. Acupuncture at Baihui (DU20) and Qubin (GB7) acupoints was performed at a depth of 1.0 inch, 12 hours after blood injection, once every 24 hours. The needle was rotated at 200 r/min for 5 minutes, For each 30-minute session, needling at 200 r/min was performed for three sessions, each lasting 5 minutes. For the positive control group, at 6 hours, and 1, 2, 3 and 7 days after induction of hemorrhage, the rats were intraperitoneally injected with 1 mL aniracetam (0.75 mg/mL), three times a day. The Bederson behavioral test was used to assess palsy in the contralateral limbs. Western blot assay was used to examine the expression levels of Nestin and basic fibroblast growth factor in the basal ganglia. Immunohistochemistry was performed to count the number of Nestin- and glial cell line-derived neurotrophic factor-positive cells in the basal ganglia. Acupuncture effectively reduced hemorrhage and brain edema, elevated the expression levels of Nestin and basic fibroblast growth factor in the basal ganglia, and increased the number of Nestin- and glial cell line-derived neurotrophic factor-positive cells in the basal ganglia. Together, these findings suggest that acupuncture promotes functional recovery after cerebral hemorrhage by increasing the expression of neurotrophic factors. The study was approved by the Committee for Experimental Animals of Heilongjiang Medical Laboratory Animal Center (approval No. 2017061001) on June 10, 2017.

RESUMO

Baihui (DU20)-penetrating-Qubin (GB7) acupuncture can inhibit inflammatory reactions and activate signaling pathways related to proliferation after intracerebral hemorrhage. However, there is no research showing the relationship between this treatment and cell apoptosis. Rat models of intracerebral hemorrhage were established by injecting 60 µL of autologous blood into the right side of the caudate-putamen. Six hours later, the needle traveled subcutaneously from the Baihui acupoint to Qubin acupoint. The needle was alternately rotated (180 ± 10 turns/min) manually along clockwise and counter-clockwise directions. Stimulation lasted for 7 days, and was performed three times each for 6 minutes with 6-minute intervals between stimulations. Rats intraperitoneally receiving Sonic hedgehog pathway activator, purmorphamine (1 mg/kg per day), served as positive controls. Motor and sensory function were assessed using the Ludmila Belayev test. Extent of pathological changes were measured in the perihemorrhagic penumbra using hematoxylin-eosin staining. Apoptosis was examined by terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick end labeling assay. Expression of smoothened (Smo) and glioma-associated homolog 1 (Gli1) was determined by western blot assay. Our results showed that Baihui-penetrating-Qubin acupuncture promoted recovery of motor and sensory function, reduced the apoptotic cell percentage in the perihemorrhagic penumbra, and up-regulated Smo and Gli1 expression. We conclude that Baihui-penetrating-Qubin acupuncture can mitigate hemorrhage and promote functional recovery of the brain in a rat model of intracerebral hemorrhage, possibly by activating the Sonic hedgehog pathway.

RESUMO

Inflammation plays an important role in nerve defects caused by intracerebral hemorrhage. Repairing brain damage by inhibiting the macrophage-inducible C-type lectin/spleen tyrosine kinase (Mincle/Syk) signaling pathway is a potential new target for treating cerebral hemorrhage. In this study, we aimed to determine whether acupuncture through Baihui (DU20) to Qubin (GB7) is an effective treatment for intracerebral hemorrhage through the Mincle/Syk signaling pathway. An intracerebral hemorrhage rat model was established by autologous blood infusion into the caudate nucleus. Acupuncture through Baihui to Qubin was performed for 30 minutes, once every 12 hours, for a total of three times. Piceatannol (34.62 mg/kg), a Syk inhibitor, was intraperitoneally injected as a control. Modified neurological severity score was used to assess neurological function. Brain water content was measured. Immunohistochemistry and western blot assay were used to detect immunoreactivity and protein expression levels of Mincle, Syk, and CARD9. Real-time polymerase chain reaction was used to determine interleukin-1ß mRNA levels. Hematoxylin-eosin staining was performed to observe histopathological changes. Our results showed that acupuncture through Baihui to Qubin remarkably improved neurological function and brain water content, and inhibited immunoreactivity and expression of Mincle, Syk, CARD9, and interkeukin-1ß. Moreover, this effect was similar to piceatannol. These findings suggest that acupuncture through Baihui to Qubin can improve neurological impairment after cerebral hemorrhage by inhibiting the Mincle/Syk signaling pathway.

RESUMO

OBJECTIVE: To investigate the clinical effects of traditional Chinese medicine (TCM) fumigation on type ⅢA prostatitis with the symptoms of damp heat and blood stasis. METHODS: We randomly divided 72 cases of type ⅢA prostatitis with the symptoms of damp heat and blood stasis into an experimental and a control group of equal number, the former treated with TCM fumigation plus oral Levofloxacin while the latter with oral Levofloxacin only. After 4 weeks of treatment, we compared the National Institute of Health Chronic Prostatitis Symptom Index (NIHCPSI) score, TCM symptoms score, maxinum flow rate (Qmax), and average urinary flow rate (Qave) between the two groups of patients. RESULTS: The total effectiveness rate was significantly higher in the experimental than in the control group (91.7% vs 61.1%, P< 0.01), while the NIHCPSI score in the experimental group was markedly decreased after treatment as compared with the baseline (14.5 ± 8.2 vs 26.5 ± 9.3, P< 0.05) and significantly lower than that in the control (14.5 ± 8.2 vs 20.6 ± 7.9, P< 0.05). Qmax was remarkably increased in the experimental group after treatment in comparison with the baseline (ï¼»21.2 ± 4.3ï¼½ vs ï¼»15.8 ± 3.6ï¼½ ml/s, P< 0.05) and the control group, and so was Qave as compared with pretreatment (ï¼»16.3 ± 3.5ï¼½ vs ï¼»10.5 ± 2.8ï¼½ ml/s, P< 0.05) and the control. However, the patients of the control group showed no statistically significant differences before and after treatment either in Qmax (ï¼»15.4 ± 3.4ï¼½ vs ï¼»16.1 ± 2.9ï¼½ ml/s, P>0.05) or in Qave (ï¼»10.9 ± 2.4ï¼½ vs ï¼»11.1 ± 2.9ï¼½ ml/s, P>0.05). CONCLUSIONS: TCM fumigation combined with Levofloxacin is an effective therapy for type ⅢA prostatitis with the symptoms of damp heat and blood stasis, which can significantly improve the symptoms, reduce the NIHCPSI score, and increase the Qmax and Qave of the patient.

RESUMO

OBJECTIVE: To observe the effect of penetrative needling of "Baihui" (GV 20) to "Qubin" (GB 7) on neurologic functions and expression of tumor necrosis factor (TNF)-α, interleukin (IL)-6 and toll-like receptor 4 (TLR-4, involving in inflammatory reactions) in the tissue around the local cerebral hematoma in rats with intracerebral hemorrhage (ICH), so as to provide evidence for clinical treatment of ICH. METHODS: Fifty-four male Wistar rats were randomly divided into sham control, mo-del and acupuncture groups, and then further divided into three time-point subgroups(1,3,7 days after modeling, n=6/subgroup). The ICH model was established by injection of the rat's autoblood (50 µL) into the putaman region (P:0.2 mm, R:3.5 mm) in a stereotaxic apparatus and confirmed by Berderson's neurologic examination grading system (0-3 points). The neurologic function was assessed by using Longa's scoring (5-points) and footfault asymmetry testing[footfault index=(contra faults-ipsi faults)/total steps in 2 min]. For penetrative needling, an acupuncture needle was inserted into GV 20 and controlled to advance to GB 7 on the affected side and retained for 30 min, once daily. The expression of TNF-α, IL-6 and TLR-4 in the cerebral tissue around the putaman was detected by immunohistochemistry. RESULTS: After penetrative needling stimulation, the increased Longa's score and footfault asymmetry score in ICH rats were significantly decreased on day 1, 3 and 7 after modeling (P<0.01), suggesting an improvement of neurologic function after the treatment. Immunohistochemical staining outcomes of the cerebral tissue surrounding the autoblood injection site showed that the expression levels of TNF-α, IL-6 and TLR-4 proteins on day 1, 3 and 7 were considerably higher in the model group than in the control group (P<0.01), and markedly lower in the acupuncture group than in the model group (P<0.01), suggesting a suppression of the proinflammatory factors and TLR-4 levels around the locus of the brain after needling intervention. A positive correlation existed between the expression levels of TLR-4 and IL-6/TNF-α. CONCLUSIONS: Penetrative needling stimulation of GV 20 to GB 7 can reduce the levels of proinflammatory factors TNF-α and IL-6, and TLR-4 in the ICH tissues in rats with cerebral hemorrhage, which may contribute to its effect in improving neurological function.

RESUMO

Notch pathway activation maintains neural stem cells in a proliferating state and increases nerve repair capacity. To date, studies have rarely focused on changes or damage to signal transduction pathways during cerebral hemorrhage. Here, we examined the effect of acupuncture in a rat model of cerebral hemorrhage. We examined four groups: in the control group, rats received no treatment. In the model group, cerebral hemorrhage models were established by infusing non-heparinized blood into the brain. In the acupuncture group, modeled rats had Baihui (DU20) and Qubin (GB7) acupoints treated once a day for 30 minutes. In the DAPT group, modeled rats had 0.15 µg/mL DAPT solution (10 mL) infused into the brain. Immunohistochemistry and western blot results showed that acupuncture effectively inhibits Notch1 and Hes1 protein expression in rat basal ganglia. These inhibitory effects were identical to DAPT, a Notch signaling pathway inhibitor. Our results suggest that acupuncture has a neuroprotective effect on cerebral hemorrhage by inhibiting Notch-Hes signaling pathway transduction in rat basal ganglia after cerebral hemorrhage.
