[Effect of Zuogui Jiangtang Jieyu Formula on intestinal flora and short-chain fatty acid metabolism in rats with diabetes mellitus complicated with depression].

This study aimed to investigate the regulatory effects of Zuogui Jiangtang Jieyu Formula(ZJJ) on the intestinal flora, short chain fatty acids(SCFAs), and neuroinflammation in rats with diabetes mellitus complicated depression(DD). The DD model was established in rats and model rats were randomly divided into a model group, a positive drug(metformin + fluoxetine) group, a ZJJ low-dose group, and a ZJJ high-dose group, with eight rats in each group. Another eight rats were assigned to the blank group. Subsequently, depressive-like behavior test was conducted on the rats, and cerebrospinal fluid samples were collected to measure pro-inflammatory cytokines [interleukin-1ß(IL-1ß), interleukin-6(IL-6), and tumor necrosis factor-α(TNF-α)]. Blood serum samples were collected to measure proteins related to the hypothalamic-pituitary-adrenal axis(HPA axis), including corticotropin-releasing hormone(CRH), adrenocorticotropic hormone(ACTH), and cortisol(CORT), as well as glucose metabolism. Gut contents were collected from each group for 16S rRNA sequencing analysis of intestinal flora and SCFAs sequencing. The results indicated that ZJJ not only improved glucose metabolism in DD rats(P<0.01) but also alleviated depressive-like behavior(P<0.05) and HPA axis hyperactivity(P<0.05 or P<0.01). Besides, it also improved the neuroinflammatory response in the brain, as evidenced by a significant reduction in pro-inflammatory cytokines in cerebrospinal fluid(P<0.05 or P<0.01). Additionally, ZJJ improved the intestinal flora, causing the intestinal flora in DD rats to resemble that of the blank group, characterized by an increased Firmicutes abundance. ZJJ significantly increased the levels of SCFAs(acetic acid, butyric acid, valeric acid, and isovaleric acid)(P<0.01). Therefore, it is deduced that ZJJ can effectively ameliorate intestinal flora dysbiosis, regulate SCFAs, and thereby improve both glucose metabolism disturbances and depressive-like behavior in DD.

Effects of anterior sciatic nerve acupuncture on lower limb paralysis after cerebral infarction: study protocol for a randomized controlled trial.

Stroke is the main cause of disability in the middle and old age. Hemiplegia, especially lower limb paralysis, often leads to the loss of self-care ability and a series of secondary injuries. The main method to improve hemiplegic limb movement is exercise therapy, but there are still many patients with disabilities after rehabilitation treatment. As one of the non-pharmacological therapies for stroke, acupuncture has been recognized to improve motor function in patients. Here, we propose a new method, anterior sciatic nerve acupuncture, which can stimulate both the femoral nerve and the sciatic nerve. We designed this study to determine the effect of this method on lower limb motor function. Sixty participants recruited with hemiplegia after cerebral infarction will be randomly assigned to the test group or control group in a 1:1 ratio. The control group will receive Xingnao Kaiqiao acupuncture, and the test group will receive anterior sciatic nerve acupuncture on this basis. All participants will get acupuncture treatment once a day, 6 times a week for 2 weeks. The primary outcome is Fugl-Meyer Assessment of Lower Extremity and the secondary outcomes are Modified Ashworth Scale and Modified Barthel Index. Data will be collected before treatment, 1 week after treatment, and 2 weeks after treatment, and then statistical analysis will be performed. This study can preliminarily verify the effect of anterior sciatic nerve acupuncture on improving lower limb motor function in patients with cerebral infarction, which may provide an alternative approach for clinical treatment of hemiplegia.

Patients will be randomized into two groups: the control group will receive conventional Xingnao Kaiqiao acupuncture and basic treatment for the stroke; based on the control group, the observation group will receive the contralateral needling at the foot of the unaffected side combined with the rehabilitation movement of the paretic hand. 12 sessions will be administrated for 2 weeks. The primary outcome, Fugl-Meyer Assessment, and the secondary outcomes, the handgrip strength, the range of motion, the modified Barthel index, and the Brunnstrom recovery stages, will be measured the recovery of the hand motor function during the 2 weeks' intervention. This study aims to investigate the instant effect of contralateral needling at the foot of the unaffected side combined with the rehabilitation treatment movement for patients with the paretic hand of Poststroke motor dysfunction and provide the previous evidence for the future large sample studies.

Andrographolide ameliorates hepatic steatosis by suppressing FATP2-mediated fatty acid uptake in mice with nonalcoholic fatty liver disease.

Excessive intrahepatocellular lipid accumulation or steatosis is caused by abnormal lipid metabolism and a common character of nonalcoholic fatty liver disease (NAFLD), which may progress into cirrhosis and hepatocellular cancer. Andrographolide (Andro) is the primary active ingredient extracted from Andrographis paniculata, showing a protective role against dietary steatosis with the mechanism not fully understood. In this study, we showed that administration of Andro (50, 100, and 200 mg/kg/day for 8 weeks, respectively) attenuated obesity and metabolic syndrome in high-fat diet (HFD)-fed mice with improved glucose tolerance, insulin sensitivity, and reduced hyperinsulinemia, hyperglycemia, and hyperlipidemia. HFD-fed mice presented hepatic steatosis, which was significantly prevented by Andro. In vitro, Andro decreased the intracellular lipid droplets in oleic acid-treated LO2 cells. The selected RT-PCR array revealed a robust expression suppression of the fatty acid transport proteins (FATPs) by Andro treatment. Most importantly, we found that Andro consistently reduced the expression of FATP2 in both the oleic acid-treated LO2 cells and liver tissues of HFD-fed mice. Overexpression of FATP2 abolished the lipid-lowering effect of Andro in oleic acid-treated LO2 cells. Andro treatment also reduced the fatty acid uptake in oleic acid-treated LO2 cells, which was blunted by FATP2 overexpression. Collectively, our findings reveal a novel mechanism underlying the anti-steatosis effect of Andro by suppressing FATP2-mediated fatty acid uptake, suggesting the potential therapeutic application of Andro in the treatment of NAFLD.

Molecular mechanism of ligustilide attenuating OGD/R injury in PC12 cells by inhibiting ferroptosis / 中国中药杂志

The aim of this study is to explore the mechanism of ligustilide, the main active constituent of essential oils of traditional Chinese medicine Angelicae Sinensis Radix, on alleviating oxygen-glucose deprivation/reperfusion(OGD/R) injury in PC12 cells from the perspective of ferroptosis. OGD/R was induced in vitro, and 12 h after ligustilide addition during reperfusion, cell viability was detected by cell counting kit-8(CCK-8) assay. DCFH-DA staining was used to detect the level of intracellular reactive oxygen species(ROS). Western blot was employed to detect the expression of ferroptosis-related proteins, glutathione peroxidase 4(GPX4), transferrin receptor 1(TFR1), and solute carrier family 7 member 11(SLC7A11), and ferritinophagy-related proteins, nuclear receptor coactivator 4(NCOA4), ferritin heavy chain 1(FTH1), and microtubule-associated protein 1 light chain 3(LC3). The fluorescence intensity of LC3 protein was analyzed by immunofluorescence staining. The content of glutathione(GSH), malondialdehyde(MDA), and Fe was detected by chemiluminescent immunoassay. The effect of ligustilide on ferroptosis was observed by overexpression of NCOA4 gene. The results showed that ligustilide increased the viability of PC12 cells damaged by OGD/R, inhibited the release of ROS, reduced the content of Fe and MDA and the expression of TFR1, NCOA4, and LC3, and improved the content of GSH and the expression of GPX4, SLC7A11, and FTH1 compared with OGD/R group. After overexpression of the key protein NCOA4 in ferritinophagy, the inhibitory effect of ligustilide on ferroptosis was partially reversed, indicating that ligustilide may alleviate OGD/R injury of PC12 cells by blocking ferritinophagy and then inhibiting ferroptosis. The mechanism by which ligustilide reduced OGD/R injury in PC12 cells is that it suppressed the ferroptosis involved in ferritinophagy.

Compound Gaoziban tablet alleviates depression toll-like receptor 4/myeloid differentiation factor 88/nuclear factor-kappa B pathway.

OBJECTIVE: To evaluate the effect of compound Gaoziban tablet (, CGZBT) on depression, and to investigate the underlying mechanism. METHODS: The components of CGZBT were analysed by high-performance liquid chromatography. Then, we assessed the effects of varying doses of CGZBT on an established chronic unpredictable mild stress (CUMS) model in rats. Whether animals were depressed was evaluated by sucrose preference test, open field test and forced swimming test. Neurotransmitters of hippocampus were detected by liquid chromatography-mass spec-trometry. Serum levels of tumor necrosis factor-alpha (TNF-α), interleukin (IL)-1ß, IL-6, IL-4, and IL-10 were measured by enzyme-linked immunosorbent assay. Expressions of toll-like receptor 4 (TLR4), myeloid differentiation factor 88 (MyD88), phospho-nuclear factor-kappa B (p-NF-κB), cyclooxygenase-2 (COX-2), ionized calcium binding adapter molecule-1 (IBA-1) were assessed by immunohistochemical staining and western blotting. RESULTS: Eight compounds were identified from CGZBT, moreover, our results showed that CGZBT effectively reversed the CUMS-induced decrease in sucrose preference, shortened the movement distance and prolonged immobility time. CGZBT significantly increased levels of 5-hydroxytryptamine, dopamine, norepinephrine, 5-hydroxyindoleacetic acid levels, and reduced the expression of TNF-α, IL-1ß, IL-6, yet increased IL-4 and IL-10. Furthermore, the expressions of TLR4, MyD88, COX-2, p-NF-κB and IBA-1 in hippocampus were effectively reversed after treatment with CGZBT. CONCLUSIONS: These results indicated that CGZBT could, at least in part, alleviate depression induced by CUMS the TLR4/MyD88/NF-κB pathway, suggesting its potential as an antidepressant drug.

Total Saponins of Panax notoginseng Activate Akt/mTOR Pathway and Exhibit Neuroprotection in vitro and in vivo against Ischemic Damage / 中国结合医学杂志

OBJECTIVE@#To reveal the neuroprotective effect and the underlying mechanisms of a mixture of the main components of Panax notoginseng saponins (TSPN) on cerebral ischemia-reperfusion injury and oxygen-glucose deprivation/reoxygenation (OGD/R) of cultured cortical neurons.@*METHODS@#The neuroprotective effect of TSPN was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay, flow cytometry and live/dead cell assays. The morphology of dendrites was detected by immunofluorescence. Middle cerebral artery occlusion (MCAO) was developed in rats as a model of cerebral ischemia-reperfusion. The neuroprotective effect of TSPN was evaluated by neurological scoring, tail suspension test, 2,3,5-triphenyltetrazolium chloride (TTC) and Nissl stainings. Western blot analysis, immunohistochemistry and immunofluorescence were used to measure the changes in the Akt/mammalian target of rapamycin (mTOR) signaling pathway.@*RESULTS@#MTT showed that TSPN (50, 25 and 12.5 µ g/mL) protected cortical neurons after OGD/R treatment (P<0.01 or P<0.05). Flow cytometry and live/dead cell assays indicated that 25 µ g/mL TSPN decreased neuronal apoptosis (P<0.05), and immunofluorescence showed that 25 µ g/mL TSPN restored the dendritic morphology of damaged neurons (P<0.05). Moreover, 12.5 µ g/mL TSPN downregulated the expression of Beclin-1, Cleaved-caspase 3 and LC3B-II/LC3B-I, and upregulated the levels of phosphorylated (p)-Akt and p-mTOR (P<0.01 or P<0.05). In the MCAO model, 50 µ g/mL TSPN improved defective neurological behavior and reduced infarct volume (P<0.05). Moreover, the expression of Beclin-1 and LC3B in cerebral ischemic penumbra was downregulated after 50 µ g/mL TSPN treatment, whereas the p-mTOR level was upregulated (P<0.05 or P<0.01).@*CONCLUSION@#TSPN promoted neuronal survival and protected dendrite integrity after OGD/R and had a potential therapeutic effect by alleviating neurological deficits and reversing neuronal loss. TSPN promoted p-mTOR and inhibited Beclin-1 to alleviate ischemic damage, which may be the mechanism that underlies the neuroprotective activity of TSPN.

OBJECTIVE: Taking the neoangiogenesis process of post-infarction as the research point, to investigate the basic law of neovascularization with time and the effect of electroacupuncture intervention on proliferation of local blood vessels. METHODS: Ninety-six Wistar rats were randomly and evenly divided into model and electroacupuncture groups. The rat models of middle cerebral artery infarction were established by suture method. Immediately after modeling, the rats in the electroacupuncture group were given electrical stimulation (15 Hz, 1mA, 20 minutes) at the Renzhong (Du26) acupoint. The rats in the model group received similar procedures with the exception of no treatment. The angiogenesis was observed using double-immunofluorescence labeling for von Wilebrand Factor (vWF) and Ki-67 antibodies at 3, 6, 12, 24, 48 hours and 3, 7, 12 days after middle cerebral artery occlusion. RESULTS AND CONCLUSION:In the model group, vascular endothelial cel proliferation in the peri-infarct region was not observed at 3, 6 and 12 hours, occurred at 24 hours, increased at 48 hours, reached a maximum at 3 days, began to decrease at 7 days, and disappeared at 12 days after middle cerebral artery occlusion. In the electroacupuncture group, vascular endothelial cel proliferation in the peri-infarct region was not observed at 3 and 6 hours, occurred at 12 hours, increased at 24 and 48 hours, peaked at 3 days, began to decerase at 7 days, and disappeared at 12 days after middle cerebral artery occlusion. Compared with the model group, the time at which vascular endothelial cel proliferation started was earlier, and the number of proliferated vascular endothelial cels was greater in the electroacupuncture group. Vascular endothelial cel proliferation in the infarcted regions and contralateral hemisphere was not observed in either group at al designated time points. These results demonstrate that electroacupuncture intervention can improve the prognosis of cerebral infarction by promoting the proliferation of vascular endothelial cels in the peri-infarct region and advancing the time at which vascular endothelial cel proliferation started in rat models of middle cerebral artery occlusion.
