RESUMEN
Chronic fatigue syndrome is a neurological disorder characterized by extreme fatigue that lasts for a long time and doesn't alleviate with rest. The number of the cases has been increasing during the era of COVID-19 pandemic. Acupuncture may have some effect on chronic fatigue syndrome, but its mechanism remains unclear. This article was to summarize the specific manifestations of abnormal central mechanism in patients with chronic fatigue syndrome through laboratory tests and neuroimaging. It was found from the laboratory evaluation that there were changes in the structure of the frontal cortex, thalamus and other brain tissues; factors, including IFN-α and IL-10 in cerebrospinal fluid were found abnormal; results of oxidative and nitrosative stress and changes in neurobiochemical substances, e.g. hypothalamus hormone levels and neurotransmitter concentrations, were observed. With magnetic resonance imaging and positron emission tomography, it was shown that the partial brain of persons with chronic fatigue syndrome had morphological changes with diminished grey matter and white; changes in cerebral blood flow velocity caused by decreased perfusion and functional activity with abnormal connectivity in brain were detected. In addition, there was significant decrease in glucose metabolism accompanied with neuroinflammatory response; metabolic disorders of serotonergic, cholinergic, glutamatergic and γ-aminobutyric acid energy neurotransmitters were also discovered. The regulatory effect of acupuncture on the above central neurological abnormalities in chronic fatigue syndrome model animals was elaborated, and the direction for further research was analyzed in order to provide ideas for further research on the central mechanism of acupuncture treatment for chronic fatigue syndrome.
RESUMEN
Ischemic stroke is the predominant cause of long-term disability and death worldwide. It is attributable to the sudden interruption of regional cerebral blood flow, resulting in brain cell death and neurological impairment. Acupuncture is a widely used adjuvant treatment for ischemic stroke in China and shows promising efficacy in clinical practice. This review mainly focused on the evidence to illustrate several possible mechanisms of acupuncture therapy on cerebral perfusion in ischemic stroke. Studies have shown that acupuncture is probably effective in the enhancement of cerebral perfusion after ischemic stroke. It promotes the improvement of hemodynamics, the release of vasoactive substances, the formation of new blood vessels, as well as the restitution of microcirculation. Multiple factors may contribute to the variability in acupuncture's therapeutic effects, including the acupoint selection, stimulation frequency and intensity, and retaining needle time. Acupuncture has the potential to become a non-pharmacological adjuvant approach to enhance cerebral perfusion in ischemic stroke. Future studies are required to gain our insight into acupuncture as well as accelerate its clinical translation.
RESUMEN
Intestinal flora dysbiosis may play an important role in the occurrence and development of chronic fatigue syndrome (CFS), which may induce the inflammatory response and metabolic disturbance of patients with CFS. Acupuncture and moxibustion may achieve anti-fatigue effect by affecting the diversity and quantity of intestinal flora, improving intestinal barrier function, and regulating brain-gut peptides.

OBJECTIVE: To observe the effect of electroacupuncture (EA) on the expression of NF-κB p65 in hippocampus and the morphology of hippocampus in rats with chronic fatigue syndrome (CFS), so as to explore its mechanism in improving cognitive dysfunction of CFS. METHODS: Forty-eight SD rats were randomly divided into control, model, EA and inhibitor groups (n=12 in each group). The CFS model was established by multi-factor compound stress stimulation method. Rats of the EA group received EA (50 Hz, 1 mA) at "Baihui" (GV20), Emotional Area I and bilateral Sensory Area for 30 min, once daily for 15 days. For rats in the inhibitor group, pyrrolidine dithiocarbamate (100 mg·kg-1·d-1) was injected intraperitoneally, once a day for 15 days. Learning and memory ability was evaluated by Morris water maze test. HE staining was used to observe the morphology of hippocampus. Western blot was used to determine the expression level of NF-κB p65 in hippocampus. RESULTS: After mode-ling, the general status score was increased ï¼P<0.01ï¼, the escape latency was prolonged(P<0.01), the times of crossing the platform was decreased(P<0.01), and the expression level of NF-κB p65 in hippocampus tissue was significantly increased (P<0.05) in the model group compared with the control group. Compared with the model group, the general status score was decreased ï¼P<0.01ï¼, the escape latency was shortened(P<0.01), the times of crossing the platform was increased(P<0.01), and the expression level of NF-κB p65 in hippocampus tissue was significantly decreased (P<0.05) in the EA and inhibitor groups. HE staining showed that in the model group, the hippocampal nerve cells were arranged disorderly, the structure was loose, and the number of apoptotic bodies and inflammatory cells was significantly increased. The degree of tissue damage of the EA and inhibitor groups was milder than that of the model group. CONCLUSION: EA can improve the cognitive function in CFS rats, which may be associated with its effect in inhibiting the expression of NF-κB and reducing the inflammation response in hippocampus.

Rhaponticin is a constituent isolated from numerous medicinal herbs. It has been reported earlier that rhaponticin possesses numerous biological effects like antiallergic, antidiabetic, hepatoprotective, and antithrombosis. The goal of this exploration was to scrutinize the therapeutic potential of rhaponticin on ovariectomy (OVX)-triggered osteoporosis in rats. Female Sprague Dawley rats were arbitrarily allocated to a sham-operated control group I, group II, which underwent OVX, and groups III and IV that underwent OVX were administered with rhaponticin (10 and 20 mg/kg). Rhaponticin was supplemented orally after 4 weeks of OVX and continued for about 16 weeks. Our findings exhibit that rhaponticin prevented the BMD diminution of femurs, induced by OVX, and protected the worsening of trabecular microarchitecture that are assisted through a noteworthy decline in skeletal remodeling as noticed through the diminished status of bone markers in a dose-dependent manner (10 and 20 mg/kg). OVX rats treated with rhaponticin efficiently enhanced body weight, lipid profiles, uterine index, bone turnover markers, inflammatory markers, and augmented the incidence of calcium in the OVX rats. Rhaponticin was established to restrain the functions of acid phosphatase, estradiol, and bone gla protein in OVX rats. Also, rhaponticin displayed some beneficial effects on histomorphometric and histopathological examination. It was observed that tabular area and thickness were reinstated in sham control and rhaponticin-treated OVX rats. We recognized that rhaponticin did not induce a damaging outcome on the skeletal organization of OVX rats. Moreover, we denote that rhaponticin can be an exceptional agent for the treatment and deal with associated bone diseases.

RESUMEN
PURPOSE: The research aimed to identify the active component from Punica granatum L. to alleviate ischemia/reperfusion injury and clarify the underlying mechanism of the active component alleviating ischemia/reperfusion injury. MATERIALS AND METHODS: The SH-SY5Y cell model of oxygen-glucose deprivation/reoxygenation (OGD/R) was established to simulate the ischemia/reperfusion injury. According to the strategy of bioassay-guided isolation, the active component of punicalin from Punica granatum L. was identified. Flow cytometry and Western blotting were employed to evaluate the effects of OGD/R and/or punicalin on cell cycle arrest. Immunofluorescence assay was applied to assess the nucleus translocation. The relative content of ROS and GSH and the enzyme activities of CAT and SOD were examined using ELISA. RESULTS: The data of bioassay-guided isolation showed that punicalin from Punica granatum L. could alleviate OGD/R-induced cell injury in SH-SY5Y cells. Flow cytometry analysis and Western blotting for probing the expression of CDK1, p-CDK1, cyclin B1, and p21 revealed that punicalin could relieve OGD/R-induced cell cycle G0/G1 arrest. Additionally, immunofluorescence assay and Western blotting for probing the expression of TGF-ß and p-Smad2/p-Smad3 showed that punicalin could relieve the OGD/R-induced TGF-ß/Smad pathway. Furthermore, the TGF-ß/Smad pathway inhibitor of LY2157299 was employed to confirm that the TGF-ß/Smad pathway is crucial to the effect of punicalin. At last, it was indicated that punicalin could relieve OGD/R-induced oxidative stress. CONCLUSION: Punicalin, an active component from Punica granatum L., was identified as a protective agent to alleviate the OGD/R-induced cell injury, which could exert the protective effect via TGF-ß/Smad pathway-regulated oxidative stress and cell cycle arrest in SH-SY5Y cells.
RESUMEN
The research progress of acupuncture analgesia in recent years is analyzed to summarize the analgesic mechanism of acupuncture on neuropathic pain. The analgesic mechanism of acupuncture on neuropathic pain is discussed from peripheral level and central level, including peripheral sensitization and immune inflammatory response, changes of ion channel, central sensitization, regulation of cell signal pathway, activation of spinal glial cells, etc. It is suggested that the focus of future research should include conducting in-vitro studies with the help of multi-omics technology to detect the changes of metabolic substances and signal pathway molecules in patients with neuropathic pain before and after acupuncture to further clarify the mechanism of acupuncture analgesia.

OBJECTIVE: To evaluate the effect of teriparatide on life quality in patients with postmenopausal osteoporosis. METHODS: Patients treated from January 2014 to December 2016 were retrospectively included. Patients were divided into two groups according the treatment received. Those in the teriparatide treatment group were followed up for 24 months, and patients in the control group received calcium supplements and vitamin D. Scores for back pain using a visual analog scale (VAS) and score of the Oswestry Disability Index (ODI) and 36-item Short Form Health Survey of life quality (SF-36) were evaluated at 3, 6, 12, and 24 months and compared between the groups. RESULTS: In total, 126 patients were included in the teriparatide treatment group and 127 in the control group. There were no significant differences between the groups concerning body mass index, bone density, VAS back pain score, ODI, and SF-36 life quality scores at baseline. At 3, 6, 12, and 24 months' follow-up, VAS scores were significantly lower in the treatment group than in controls; ODI and SF-36 scores were significantly higher in the treatment group than in the control group. CONCLUSION: Teriparatide can significantly decrease pain and increase mobility and life quality in patients with postmenopausal osteoporosis.

OBJECTIVE: To evaluate the effect of "Shuganjieyu" (SGJY) capsules on neuronal apoptosis in hippocampal CA3 area and the expression of caspase-3 in the brain of rat depression model, and to investigate its pharmacological mechanisms in depression treatment. METHODS: Adult male SD rats were randomly divided into 4 groups: a control, a model, a SGJY and a fluoxetine group. The rat depression model was established under chronic unpredictable mild stress (CUMS) and separate feeding. The behaviors were measured by open-field test, sucrose consumption and forced swimming test. We observed the neuronal morphology structure and neuronal apoptosis in the hippocampal CA3 area. We detected the rat caspase-3 expression level of medial prefrontal cortex ( mPFC) and hippocampal CA3 area by Western blot. RESULTS: After 21-day stress, compared with the model group, spontaneous activity and sucrose consumption and preference percentage of the rats in the SGJY group significantly increased, while the immobility time in forced swimming test, the number of apoptotic cells and the protein levels of caspase-3 significantly reduced (P<0.01 or 0.05). There was no significant difference between the SGJY group and the fluoxetine group (P>0.05). CONCLUSION: SGJY capsules can reduce the depression symptoms of CUMS and help to increase hippocampal neuron generation, survival and neogenesis, reduce the protein levels of caspase-3, and reverse neurocyte apoptosis in the rat depression model with the same efficacy as fluoxetine.
