Study on the clinical efficacy of Mongolian medicine in the treatment of osteoarthritis.

OBJECTIVE: The object of this paper was to evaluate the clinical efficacy and safety of Mongolian medicine in the treatment of osteoarthritis (OA). This was completed by offering evidence to provide a clinical basis for the treatment of OA. We explored the mechanism of the sticking application of Mongolian medicine. METHOD: A total of 123 patients with OA diagnosed in the Affiliated Hospital of Inner Mongolia Medical University from January 2017 to December 2017 were enrolled. The clinical data of the patients were retrospectively analyzed. Patients were divided into three groups according to the medication they were using at the time: The strapping group, the glucosamine hydrochloride group, and the Mongolian medicine group, with 41 patients in each group. The treatment indicators of the included patients 2 weeks after the treatment and 4 weeks after the treatment were fully recorded in our hospital. The levels of CGRP, TNF-α, MMP-3, VEGF, and IL-10 before and after treatment were measured by ELISA. The auxiliary diagnostic index was X-ray film. RESULTS: Compared with the control group, the Mongolian medicine group improved the symptoms of pain, swelling, limited movement, and daily life quality of patients to different degrees. There was a significant decrease in the VAS score at each time point of the Mongolian medicine group (P < 0.05). tThe scores of bodily pain in SF-36 QOL were significantly higher in the Mongolian medicine group at different time points (P < 0.05). After treatment, the levels of MMP-3, TNF-α, VEGF, and CGRP in the Mongolian medicine group were significantly lower than those before the treatment (P < 0.05). CONCLUSION: Mongolian medicine can inhibit the expression of MMP-3, TNF-α, VEGF, and CGRP in serum, and up-regulate the trend of IL-10, alleviating the inflammatory reaction. It has a good curative effect in the treatment of OA patients. It is better than western medicine in pain, swelling, and improving bone and joint function index.

Overview of Traditional Mongolian Medical Warm Acupuncture.

Mongolian medical warm acupuncture is a traditional therapy of Mongolian medicine and was developed by people living on the Mongolian Plateau. This kind of traditional oriental medicine has a long history. The main characteristics of Mongolian medical warm acupuncture are the acupoints and the needles used. Its theory is based on the human anatomical structure and the distinct local culture. Mongolian medical warm acupuncture has been practiced for centuries and proved to be very effective in the treatment of age-related diseases, including the musculoskeletal and nervous diseases. This paper aims to briefly introduce the history and scope of Mongolian medical warm acupuncture, with a particular focus on age-related diseases, where Mongolian medical warm acupuncture has shown significant beneficial effects.

Influence of warm acupuncture on gut microbiota and metabolites in rats with insomnia induced by PCPA.

BACKGROUND: Insomnia is the most common of the sleep disorders. Current pharmacotherapy treatment options are usually associated with adverse effects and withdrawal phenomena. Therapeutic alternatives with a more favorable safety profile for patients are needed. Mongolian medical warm acupuncture (MMWA) is an emerging therapeutic option for treating insomnia. However, the underlying mechanisms responsible for the anti-insomnia efficacy of the MMWA remain unclear. This study aims to investigate the effect of the MMWA on the alterations of the gut microbiota and serum metabolome in rats with insomnia. RESULTS: We found that the relative abundances of gut bacteria and the concentrations of several serum metabolites were obviously altered in PCPA-induced insomnia rats. The MMWA treatment exerted an anti-insomnia effect. In addition, the dysbiosis of the gut microbiota and the serum metabolites were ameliorated by the MMWA. Correlation analysis between the gut microbiota and metabolites suggested that the levels of Amide c18, Benzoyl chloride, Cytosine, and N, n-dimethylarginine were positively correlated with the relative abundance of Clostridium XlVa and Blautia, which characterized the insomnia rats. KEGG enrichment analysis identified the cAMP signaling pathway involving anti-insomnia effect of the MMWA. Moreover, the MMWA intervention significantly increased contents of butyrate in feces, while effectively inhibited the expression level of GAT-1 in brain tissues. CONCLUSION: This study reveals that the MMWA intervention might have a major impact on the modulation of host gut microbiota and metabolites, which in turn have a crucial role in the regulation of the host's signaling pathways associated with insomnia. The present study could provide useful ideas for the study of the intervention mechanisms of the MMWA in insomnia rat models.

Pathogenesis of Brucella epididymoorchitis-game of Brucella death.

Brucellosis is a worldwide zoonotic disease caused by Brucella spp. Human infection often results from direct contact with tissues from infected animals or by consumption of undercooked meat and unpasteurised dairy products, causing serious economic losses and public health problems. The male genitourinary system is a common involved system in patients with brucellosis. Among them, unilateral orchitis and epididymitis are the most common. Although the clinical and imaging aspect of orchi-epididymitis caused by brucellosis have been widely described, the cellular and molecular mechanisms involved in the damage and the immune response in testis and epididymis have not been fully elucidated. In this review, we first summarised the clinical characteristics of Brucella epididymo-orchitis and the composition of testicular and epididymal immune system. Secondly, with regard to the mechanism of Brucella epididymoorchitis, we mainly discussed the process of Brucella invading testis and epididymis in temporal and spatial order, including i) Brucella evades innate immune recognition of testicular PRRs；ii) Brucella overcomes the immune storm triggered by the invasion of testis through bacterial lipoproteins and virulence factors, and changes the secretion mode of cytokines; iii) Brucella breaks through the blood-testis barrier with the help of macrophages, and inflammatory cytokines promote the oxidative stress of Sertoli cells, damaging the integrity of BTB; iv) Brucella inhibits apoptosis of testicular phagocytes. Finally, we revealed the structure and sequence of testis invaded by Brucella at the tissue level. This review will enable us to better understand the pathogenesis of orchi-epididymitis caused by brucellosis and shed light on the development of new treatment strategies for the treatment of brucellosis and the prevention of transition to chronic form. Facing the testicle with immunity privilege, Brucella is like Bruce Lee in the movie Game of Death, winning is survival while losing is death.HIGHLIGHTSWe summarized the clinical features and pathological changes of Brucellaepididymoorchitis.Our research reveals the pathogenesis of Brucella epididymoorchitis, which mainly includes the subversion of testicular immune privilege by Brucella and a series of destructive reactions derived from it.As a basic framework and valuable resource, this study can promote the exploration of the pathogenesis of Brucella and provide reference for determining new therapeutic targets for brucellosis in the future.

Interaction between piperine and genes associated with sciatica and its mechanism based on molecular docking technology and network pharmacology.

Piperine is the main active component of Piper longum L., which is also the main component of anti-sciatica Mongolian medicine Naru Sanwei pill. It has many pharmacological activities such as anti-inflammatory and immune regulation. This paper aims to preliminarily explore the potential mechanism of piperine in the treatment of sciatica through network pharmacology and molecular docking. TCMSP, ETCM database and literature mining were used to collect the active compounds of Piper longum L. Swiss TargetPrediction and SuperPred server were used to find the targets of compounds. At the same time, CTD database was used to collect the targets of sciatica. Then the above targets were compared and analyzed to select the targets of anti-sciatica in Piper longum L. The Go (gene ontology) annotation and KEGG pathway of the targets were enriched and analyzed by Metascape database platform. The molecular docking between the effective components and the targets was verified by Autodock. After that, the sciatica model of rats was established and treated with piperine. The expression level of inflammatory factors and proteins in the serum and tissues of rat sciatic nerve were detected by ELISA and Western blot. HE staining and immunohistochemistry were carried out on the sciatica tissues of rats. The results showed that Piper longum L. can regulate the development of sciatica and affect the expressions of PPARG and NF-kB1 through its active ingredient piperine, and there is endogenous interaction between PPARG and NF-kB1.

Long Noncoding RNA ZFAS1 Promotes Progression of NSCLC via Regulating of miR-590-3p.

The incidence and mortality rate of nonsmall cell lung cancer (NSCLC) are continuously increasing. Recently, the important roles of long noncoding ribonucleic acid (lncRNA) zinc finger antisense1 (ZFAS1) in the development of many disease have been proved. However, the roles of ZFAS1 in NSCLC are still not completely understood. Thus, this study aimed to explore the potential roles and underlying mechanisms of lncRNA ZFAS1 in the progression of NSCLC. Our results demonstrated that lncRNA ZFAS1 expression was significantly upregulated in NSCLC tissues and cell lines. Loss-of-function experiments revealed that lncRNA ZFAS1 inhibition could remarkably suppress NSCLC cells proliferation in vitro. Bioinformatic analysis and luciferase reporter assay revealed that lncRNA ZFAS1 directly interacted with miR-590-3p. Rescue experiments showed that miR-590-3p inhibitor reversed the cell proliferation function of lncRNA ZFAS1 knockdown in vitro. Furthermore, we confirmed that lncRNA ZFAS1 inhibited cell division cycle 42 (Cdc42) expression by regulating of miR-590-3p in NSCLC cells. Therefore, our study indicates that lncRNA ZFAS1/miR-590-3p axis is involved in NSCLC cell proliferation. It also suggests that lncRNA ZFAS1 is a putative tumor oncogene in NSCLC.

Identification lncRNA LOC102551149/miR-23a-5p pathway in hepatic fibrosis.

BACKGROUND: Hepatic fibrosis is a worldwide incurable disease; due to the complex and unclear mechanism, there lack the effective therapeutic targets. However, the mechanism of miR-23a-5p underling this pathological process is largely not clear. The purpose of this study was to investigate the role of miR-23a-5p in hepatic fibrosis and HSC activation. METHODS: The content of miR-23a-5p in hepatic fibrosis induced by N-nitrosodimethylamine (NDMA) and HSC activation induced by platelet-derived growth factor (PDGF) was detected by qRT-PCR. H&E staining, Masson staining and Shear wave electrography (SWE) were used to detect the degree of hepatic fibrosis. Immunohistochemistry staining, qRT-PCR and Western blot detect the related markers of liver fibrosis or HSC activation, as well as the related pathway genes and proteins. Dual-luciferase reporter system verifies the interaction between miR-23a-5p with PTEN or miR-23a-5p with lncRNA LOC102551149 in HSC-T6. siRNA and miRNA mimic transfer to HSC-T6 to detect the function of lncRNA LOC102551149 and miR-23a-5p on HSC activation. RESULTS: After hepatic fibrosis and HSC activation happened, the expression of miR-23a-5p was up-regulated, whereas anti-miR-23a-5p can alleviate hepatic fibrosis and HSC activation. Further research shows miR-23a-5p can target PTEN and degrade it, causing activation of PI3K/Akt/mTOR/Snail pathway. lncRNA LOC102551149 can be used as a competition endogenous RNA (ceRNA) targeting miR-23a-5p through base pairing, and siRNA LOC102551149 or exogenous miR-23a-5p can induce HSC activation through PI3K/Akt/mTOR/Snail pathway. CONCLUSION: We demonstrate mechanism pathway of miR-23a-5p on hepatic fibrosis and HSC activation, which may develop a therapeutic target for hepatic fibrosis.

lncRNA GAS5 restrains CCl4-induced hepatic fibrosis by targeting miR-23a through the PTEN/PI3K/Akt signaling pathway.

Hepatic fibrosis is chronic liver damage with many causes that has a relatively high death rate. The current study showed that long noncoding RNA (lncRNA) growth arrest-specific transcript 5 (GAS5), microRNA-23a (miR-23a), and phosphatase and tensin homolog (PTEN) play important roles in the pathological process of hepatic fibrosis but have a relatively unclear regulatory mechanism. This study aimed to investigate the roles of lncRNA GAS5, miR-23a, and PTEN in the pathological process of hepatic fibrosis and hepatic stellate cell (HSC) activation. We used carbon tetrachloride (CCl4) intraperitoneal injections to establish a rat hepatic fibrosis model and exogenous transforming growth factor-ß1 to establish an HSC activation model. Quantitative RT-PCR, Western blot, dual-luciferase reporter system, and RNA pull-down assays were used to investigate which microRNAs and lncRNAs participate in the process of hepatic fibrosis and HSC activation. miR-23a expression increased significantly in hepatic fibrosis tissues and activated HSCs. miR-23a interaction with and degradation of PTEN further influenced the downstream signaling pathway phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin/Snail (PI3K/Akt/mTOR/Snail), causing E-cadherin expression levels to decrease and α-smooth muscle actin and collagen I expression levels to increase. lncRNA GAS5 can be used as a sponge platform for miR-23a to decrease miR-23a expression levels competitively. We revealed the role of the lncRNA GAS5/miR-23a/PTEN/PI3K/Akt/mTOR/Snail signaling pathway in hepatic fibrosis, providing molecular targets for the treatment of hepatic fibrosis. NEW & NOTEWORTHY This is the first study revealing that microRNA-23a (miR-23a) promotes hepatic fibrosis through the phosphatase and tensin homolog/phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin/Snail signaling pathway, and long noncoding RNA (lncRNA) growth arrest-specific transcript 5 (GAS5) can act as a sponge platform for miR-23a. Therefore, lncRNA GAS5/miR-23a may bring molecular targets for hepatic fibrosis therapy.

Effects of Mongolian Warm Acupuncture on iNOS/NO and Inflammatory Cytokines in the Hippocampus of Chronic Fatigue Rats.

The inducible nitric oxide synthase/nitric oxide (iNOS/NO) signaling pathway and inflammatory cytokines play important roles in the pathogenesis of exercise-induced fatigue. Studies have found that Mongolian warm acupuncture (WA) could alleviate exercise-induced fatigue. However, the exact mechanisms underlying its effects remain unclear. In the present study, we investigated the effects of Mongolian WA on iNOS/NO signaling pathway and proinflammatory cytokines in a chronic exhaustive swimming-induced fatigue rat model. Animals were randomly divided into Control group, Ctrl + WA group, Model group, and Model + WA group. The body weight, exhaustive swimming time test, and Morris water maze test were performed before and after the chronic exhaustive swimming. The serum levels of interleukin-1ß (IL-1ß), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), and iNOS were detected by enzyme linked immunosorbent assay (ELISA). The mRNA expressions of IL-1ß, IL-6, TNF-α, IFN-γ, and iNOS in the hippocampus were measured by real-time polymerase chain reaction (RT-PCR). Moreover, the protein expression of iNOS in the hippocampus was measured by western blot, and the NO productions in the serum and hippocampus were detected by Griess reaction system. Chronic exhaustive exercise significantly reduced the body weight and exhaustive swimming time, and induced impairment in learning and memory, and which were reversed by WA treatment. Chronic exhaustive exercise also increased the expressions of iNOS and proinflammatory cytokines, while WA treatment significantly decreased the level of iNOS and proinflammatory cytokines. However, chronic exhaustive exercise did not affect the NO production. These findings demonstrated that WA could alleviate the chronic exhaustive swimming-induced fatigue and improve the learning and memory ability, and the actions might be related to the reduction of inflammatory response and iNOS expression.

Research on Roles of Mongolian Medical Warm Acupuncture in Inhibiting p38 MAPK Activation and Apoptosis of Nucleus Pulposus Cells.

BACKGROUND: Mongolian medical warm acupuncture has a desirable therapeutic effect on sciatica. Apoptosis of the nucleus pulposus cells is considered to play an important role in sciatica. Evidence has demonstrated that oxidative stress and its induced activation of the signaling pathways play important roles in sciatica. However, further research is expected to reveal whether Mongolian medical warm acupuncture can inhibit the apoptosis of nucleus pulposus cells and oxidative stress. OBJECTIVE: To study the effect of the p38 MAPK pathway activated by the generated ROS on apoptosis and the expression of the genes related to the balance of the extracellular matrix metabolism during treatment of sciatica with Mongolian medical warm acupuncture. METHOD: The volume of the active oxygen generated in the nucleus pulposus cells was detected following intervention of Mongolian medical warm acupuncture. The p38 MAPK phosphorylation level was detected with Western blot. The genes are related to the metabolism of the nucleus pulposus extracellular matrix. RESULT: Mongolian medical warm acupuncture reduced the active oxygen within the nucleus pulposus cells and inhibited the activation of the p38 MAPK pathway (P=0.013). Meanwhile, it upregulated the gene expression of Type II collagen, aggrecan, Sox-9, and tissue matrix metalloproteinase reagent 1 (P-0.015; P=0.025; P=0.031; P=0.045) and downregulated the gene expression of matrix metalloproteinase 3 (P=0.015). CONCLUSION: Mongolian medical warm acupuncture may inhibit apoptosis of nucleus pulposus cells and activation of the extracellular matrix decomposition metabolism pathway and promote its anabolism. This process may rely on the oxidative stress matrix of the p38 MAPK pathway.

Mechanism of Mongolian medical warm acupuncture in treating insomnia by regulating miR-101a in rats with insomnia.

MicroRNAs (miRNAs or miRs) and the target genes before and after warm acupuncture at the genetic level were assessed, and the cytokines and neurotransmitters related to insomnia were studied. Male Sprague-Dawley rats were used to create PCPA insomnia rat models and randomly divided into the normal, model, warm acupuncture, and drug groups. The Dinghui Acupoint, Heyi Acupoint, and Xin Acupoint were inserted in the Mongolian medicine warm acupuncture group. The differential expression profile of microRNA in the brain tissue of the insomnia rats was determined before and after Mongolian medicine warm acupuncture for establishment of miR-101a mimics and inhibitor. qPCR was used to detect the expression level of miR-101a. Western blotting was used to detect the expression level of PAX8. The rats receiving Mongolian medicine warm acupuncture had 141 miRNAs with differential expression compared with the normal rats. The expression level of miR-101a in the cells of the hippocampus of the insomnia rats transfected with miR-101a mimics increased significantly at 72 h (P<0.05). The activity of the neuronal cells transfected with miR-101a inhibitor increased significantly at 72 h (P<0.05). The western blotting result indicated that the expression of the PAX8 protein in the neuronal cells of the insomnia model rats was inhibited and downregulated significantly at 72 h after addition of miR-101a mimics compared with that in the scramble added group (P<0.01). The levels of the interleukins IL-1, IL-2, and IL-6 and the tumor necrosis factor-α in the hypothalamus, hippocampus, and prefrontal cortex decreased significantly compared with those in the blank control group (P<0.05). The levels of noradrenaline, dopamine, and glutamic decreased significantly following warm acupuncture or western medicine treatment (P<0.05). In conclusion, this study demonstrates that the upregulation of miR-101a in the rats treated with warm acupuncture is directly associated with PAX8 regulation.

Effect of two GABA-ergic drugs on the cognitive functions of rapid eye movement in sleep-deprived and recovered rats.

Rapid eye movement (REM) sleep is closely associated with nervous functions. The present study aimed to evaluate the effects of gabazine and tiagabine on the cognitive functions (CF) of REM sleep-deprived and sleep recovered rats. Rats were divided into REM sleep deprivation, blank control (CC) and environmental groups. The REM sleep deprivation group was further divided into non-operation (nonOP), sham-operated (Sham), gabazine (SR) and tiagabine groups. Each group was evaluated over five time points: Sleep deprived for 1 day (SD 1 day), SD 3 day, SD 5 day, sleep recovery 6 h (RS 6 h) and RS 12 h. A rat model of REM sleep deprivation was established by a modified multi-platform water method, with CF assessed by Morris water maze. Hypothalamic γ-aminobutyric acid (GABA) and glutamic acid contents were measured via high performance liquid chromatography. The number and morphology of hypocretin (Hcrt) neurons and Fos in the hypothalamus, and GABAARα1-induced integral optical density were detected by immunofluorescence. Compared to the CC group, the nonOP and Sham group rats CF were significantly diminished, Fos-positive and Fos-Hcrt double positive cells were significantly increased, and GABA content and GABAARα1 expression levels were significantly elevated (P<0.05). The tiagabine and CC groups exhibited similar results at three time points. The CF of rats in the SR group were diminished and the number of Fos-positive and Fos-Hcrt double positive cells were significantly increased (P<0.05) at RS 6 h and RS l2 h. GABA content and GABAARα1 expression levels were significantly increased in the SR group at all time points (P<0.05), whereas only GABAARα1 expression levels were significantly increased in the tiagabine group at SD 5 day (P<0.05). The results of the present study indicated that REM sleep deprivation diminished CF, increased the number of Hcrt neurons, GABA content and GABAARα1 expression. Furthermore, all alterations were positively correlated with deprivation time and corrected by sleep recovery, as demonstrated by single-factor multi-level variance analysis at the various time points in each group. Therefore, the Hcrt nervous system may be an eligible therapeutic target for the treatment of insomnia.

Clinical Trial Research on Mongolian Medical Warm Acupuncture in Treating Insomnia.

Objective. Insomnia is one of the most common sleep disorders. Hypnotics have poor long-term efficacy. Mongolian medical warm acupuncture has significant efficacy in treating insomnia. The paper evaluates the role of Mongolian medical warm acupuncture in treating insomnia by investigating the Mongolian medicine syndromes and conditions, Pittsburgh sleep quality index, and polysomnography indexes. Method. The patients were diagnosed in accordance with International Classification of Sleep Disorders (ICSD-2). The insomnia patients were divided into the acupuncture group (40 cases) and the estazolam group (40 cases). The patients underwent intervention of Mongolian medical warm acupuncture and estazolam. The indicators of the Mongolian medicine syndromes and conditions, Pittsburgh sleep quality index (PSQI), and polysomnography indexes (PSG) have been detected. Result. Based on the comparison of the Mongolian medicine syndrome scores between the warm acupuncture group and the drug treatment group, the result indicated P < 0.01. The clinical efficacy result showed that the effective rate (85%) in the warm acupuncture group was higher than that (70%) in the drug group. The total scores of PSQI of both groups were approximated. The sleep quality indexes of both groups decreased significantly (P < 0.05). The sleep quality index in the Mongolian medical warm acupuncture group decreased significantly (P < 0.01) and was better than that in the estazolam group. The sleep efficiency and daytime functions of the patients in the Mongolian medical warm acupuncture group improved significantly (P < 0.01). The sleep time was significantly extended (P < 0.01) in the Mongolian medical warm acupuncture group following PSG intervention. The sleep time during NREM in the Mongolian warm acupuncture group increased significantly (P < 0.01). The sleep time exhibited a decreasing trend during REM and it decreased significantly in the Mongolian warm acupuncture group (P < 0.01). The percentage of sleep time in the total sleep time during NREM3+4 in the Mongolian medical warm acupuncture group increased significantly. Conclusion. Mongolian medical warm acupuncture is efficient and safe in treating insomnia. It is able to better improve the patients' sleep time and daytime functions. It is better than that in the estazolam group following drug withdrawal in terms of improving the sleep time. It is more effective in helping the insomnia patients than hypnotics.
