ABSTRACT

Cancer, a chronic disease characterized by uncontrolled cell development, kills millions of people globally. The WHO reported over 10 million cancer deaths in 2020. Anticancer medications destroy healthy and malignant cells. Cancer treatment induces neuropathy. Anticancer drugs cause harm to spinal cord, brain, and peripheral nerve somatosensory neurons, causing chemotherapy-induced neuropathic pain. The chemotherapy-induced mechanisms underlying neuropathic pain are not fully understood. However, neuroinflammation has been identified as one of the various pathways associated with the onset of chemotherapy-induced neuropathic pain. The neuroinflammatory processes may exhibit varying characteristics based on the specific type of anticancer treatment delivered. Neuroinflammatory characteristics have been observed in the spinal cord, where microglia and astrocytes have a significant impact on the development of chemotherapy-induced peripheral neuropathy. The patient's quality of life might be affected by sensory deprivation, loss of consciousness, paralysis, and severe disability. High cancer rates and ineffective treatments are associated with this disease. Recently, histone deacetylases have become a novel treatment target for chemotherapy-induced neuropathic pain. Chemotherapy-induced neuropathic pain may be treated with histone deacetylase inhibitors. Histone deacetylase inhibitors may be a promising therapeutic treatment for chemotherapy-induced neuropathic pain. Common chemotherapeutic drugs, mechanisms, therapeutic treatments for neuropathic pain, and histone deacetylase and its inhibitors in chemotherapy-induced neuropathic pain are covered in this paper. We propose that histone deacetylase inhibitors may treat several aspects of chemotherapy-induced neuropathic pain, and identifying these inhibitors as potentially unique treatments is crucial to the development of various chemotherapeutic combination treatments.

ABSTRACT

Clinically, neuropathic pain treatment remains a challenging issue because the major therapy, centred around pharmacological intervention, is not satisfactory enough to patient by reason of low effectiveness and more adverse reaction. Therefore, it is still necessary to find more effective and safe therapy to ameliorate neuropathic pain. The purpose of this study was to explore the antinociceptive effect of Echinacoside (ECH), an active compound of Cistanche deserticola Ma, on peripheral neuropathic pain induced by chronic constriction injury (CCI) in mice, and to demonstrate its potential mechanism in vivo and vitro. In the present study, results showed that intraperitoneal administration of ECH (50, 100, and 200 mg/kg) could alleviate mechanical allodynia, cold allodynia and thermal hyperalgesia via behavioural test. Moreover, the structure and function of injured sciatic nerve by CCI were taken a turn for the better to a certain extent after ECH treatment using histopathological and electrophysiological test. Furthermore, ECH repressed the expression of the P2X7R and FKN and reduced the expression and release of the IL-1ß, IL-6 and TNF-α. Besides, ECH could decrease Ca2+ influx and Cats efflux and inhibit phosphorylation of p38MAPK. To sum up, the present study illustrated that ECH could alleviate peripheral neuropathic pain by inhibiting microglia overactivation and inflammation through P2X7R/FKN/CX3CR1 signalling pathway in spinal cord. This study would provide a new perspective and strategy for the pharmacological treatment on neuropathic pain.

ABSTRACT

The inefficient treatment using protein-based nanovaccines is largely attributed to their inadequate immunogenicity. Herein, we developed a novel fluoropolymer (PF) via ring-opening polymerization and constructed a fluoropolymer-based nanovaccine for tumor immunotherapy. Due to the existence of fluoroalkyl chains, PF not only played a crucial role in tumor antigen delivery but also exhibited a remarkable adjuvant effect in enhancing the immunogenicity of nanovaccines. The nanovaccines formed by mixing PF with a model antigen ovalbumin (OVA) enhanced the uptake of antigen proteins by dendritic cells (DCs) and promoted the maturation and antigen presentation of DCs. Compared with free OVA, PF/OVA showed better efficacy in both pre-cancer prevention and tumor treatment. Furthermore, the proportion of CD4+ T and CD8+ T cells was significantly increased in lymph nodes and tumors of mice immunized with PF/OVA. Additionally, there was a great enhancement in the levels of key anti-tumor cytokines (TNF-α and IFN-γ) in the serum of the PF/OVA immunized mice. Our research has shown that fluoropolymer PF applied as a protein vector and adjuvant has great potential for the development of nanovaccines with robust immunogenicity.

ABSTRACT

Chronic pain affects patients' physical and psychological health and quality of life, entailing a tremendous public health challenge. Currently, drugs for chronic pain are usually associated with a large number of side effects and poor efficacy. Chemokines in the neuroimmune interface combine with their receptors to regulate inflammation or mediate neuroinflammation in the peripheral and central nervous system. Targeting chemokines and their receptor-mediated neuroinflammation is an effective means to treat chronic pain. In recent years, growing evidence has shown that the expression of chemokine ligand 2 (CCL2) and its main chemokine receptor 2 (CCR2) is involved in its occurrence, development and maintenance of chronic pain. This paper summarises the relationship between the chemokine system, CCL2/CCR2 axis, and chronic pain, and the CCL2/CCR2 axis changes under different chronic pain conditions. Targeting chemokine CCL2 and its chemokine receptor CCR2 through siRNA, blocking antibodies, or small molecule antagonists may provide new therapeutic possibilities for managing chronic pain.

ABSTRACT

BACKGROUND: Stomatitis is inflammation of the oral mucosa. Angiopoietin-like protein 4 (ANGPTL4) has pleiotropic functions both anti-inflammatory and pro-inflammatory properties. In the present study, we tested whether there is a correlation between increased ANGPTL4 expression and inflammation in stomatitis mice and the mechanisms involved. METHODS AND RESULTS: In this study, the oral mucosa of mice was burned with 90% phenol and intraperitoneal injection of 5-fluorouracil to establish the model of stomatitis mice. The pathological changes of stomatitis mice were observed by H&E staining of paraffin section. The expressions of cytokines and ANGPTL4 were detected by fluorescence quantitative PCR, and the protein levels of ANGPTL4 were detected by western blot. Compared with control group, the oral mucosal structure of model mice was damaged. The expression of ANGPTL4 were significantly increased concomitantly with elevated production of anti-inflammatory cytokine (peroxisome proliferator-activated receptor alpha) and pro-inflammatory cytokines [nuclear transcription factor-kappa B, interleukin-6 (IL-6), IL-1ß, and tumor necrosis factor-α] in mice with stomatitis. CONCLUSIONS: This study suggests that ANGPTL4 may be a double-edged sword in multiple inflammatory responses in stomatitis mice.

ABSTRACT

Wing polymorphism significantly contributes to the ecological success of some insect species. For example, the brown planthopper (BPH) Nilaparvata lugens, which is one of the most destructive rice pests in Asia, can develop into either highly mobile long-winged or highly fecund short-winged adult morphs. A recent study reported a highly provocative result that the Hox gene Ultrabithorax (Ubx) is expressed in BPH forewings and showed that this wing development gene is differentially expressed in nymphs that develop into long-winged versus short-winged morphs. Here, we found that Ubx may be a mir-9a target, and used dual luciferase reporter assays and injected micro RNA (miRNA) mimics and inhibitors to confirm the interactions between mir-9a and NlUbx. We measured the mir-9a and NlUbx expression profiles in nymphs and found that the expression of these two biomolecules was negatively correlated. By rearing BPH nymphs on host rice plants with different nutritional status, we were able to characterize a regulatory cascade between insulin receptor genes, mir-9a, and NlUbx that regulate wing length in BPHs. When host quality was low, NlInR1 expression in the nymph terga increased and NlInR2 expression decreased; this led to a higher mir-9a level, which in turn reduced the NlUbx transcript level and ultimately resulted in longer wing lengths. Beyond extending our understanding of the interplay between host plant status and genetic events that modulate polymorphism, we demonstrated both the upstream signal and miRNA-based regulatory mechanism that control Ubx expression in BPH forewings.

ABSTRACT

Neuropathic pain is a refractory disease that occurs across the world and pharmacotherapy has limited efficacy and/or safety. This disease imposes a significant burden on both the somatic and mental health of patients; indeed, some patients have referred to neuropathic pain as being 'worse than death'. The pharmacological agents that are used to treat neuropathic pain at present can produce mild effects in certain patients, and induce many adverse reactions, such as sedation, dizziness, vomiting, and peripheral oedema. Therefore, there is an urgent need to discover novel drugs that are safer and more effective. Natural compounds from medical plants have become potential sources of analgesics, and evidence has shown that glycosides alleviated neuropathic pain via regulating oxidative stress, transcriptional regulation, ion channels, membrane receptors and so on. In this review, we summarize the epidemiology of neuropathic pain and the existing therapeutic drugs used for disease prevention and treatment. We also demonstrate how glycosides exhibit an antinociceptive effect on neuropathic pain in laboratory research and describe the antinociceptive mechanisms involved to facilitate the discovery of new drugs to improve the quality of life of patients experiencing neuropathic pain.

ABSTRACT

Myocardial infarction (MI) is known as a serious global problem, which has a high mortality rate and cause severe heart damage. Mounting evidence has suggested that exercise provides direct endogenous cardiac protection against various cardiovascular diseases including MI. However, the underlying mechanism of exercise's cardioprotective effect against MI has not been fully understood. Here, we found that a 4-wk swim training exerted protective effects against MI in C57 mice, as evidenced by increased cardiac function and decreased cardiac apoptosis. A plasma miRNA profiling assay was then performed, and 10 differentially expressed miRNAs were detected. Among them, miR-1192 was increased after exercise, and it exerted significant protective effect against hypoxia in cultured neonatal cardiomyocytes. In addition, intramyocardially injection of agomiR-1192 exerted similar cardioprotective effect as exercise, and inhibition of miR-1192 using antgomiR-1192 abolished the cardioprotective effect of exercise in MI mice, suggesting that exercise exerted cardioprotection against MI through upregulation of miR-1192. Furthermore, we found that miR-1192 exerted cardioprotective effect via targeting caspase 3 in cardiomyocytes. These findings suggested that exercise protects the heart against MI through upregulation of miR-1192, and miR-1192 is a novel exerkine in exercise-induced cardioprotection against MI.

ABSTRACT

Trigeminal nerve stimulation (TNS) has recently been demonstrated effective in the treatment of epilepsy and mood disorders. Here, we aim to determine the effects of TNS on epileptogenesis, cognitive function, and the associated hippocampal apoptosis and inflammatory responses. Rats were injected with pilocarpine to produce status epilepticus (SE) and the following chronic epilepsy. After SE induction, TNS treatment was conducted for 4 consecutive weeks. A pilocarpine re-injection was then used to induce a seizure in the epileptic rats. The hippocampal neuronal apoptosis induced by seizure was assessed by TUNEL staining and inflammatory responses by immunohistochemistry and enzyme-linked immunosorbent assay (ELISA). The spontaneous recurrent seizure (SRS) number was counted through video monitoring, and the cognitive function assessed through Morris Water Maze (MWM) test. TNS treatment attenuated the SRS attacks and improved the cognitive impairment in epileptic rats. A pilocarpine re-injection resulted in less hippocampal neuronal apoptosis and reduced level of interleukin-1 beta (IL-1ß), tumor necrosis factor-α (TNF-α), and microglial activation in epileptic rats with TNS treatment in comparison to the epileptic rats without TNS treatment. It is concluded that TNS treatment shortly after SE not only protected against the chronic spontaneous seizures but also improved cognitive impairments. These antiepileptic properties of TNS may be related to its attenuating effects on hippocampal apoptosis and pro-inflammatory responses.

ABSTRACT

This is a reply to the comments on our article "Linear headache: a recurrent unilateral head pain circumscribed in a line-shaped area" published in JHP 2014 Jun 26; 15:45. In the comments, the authors raise a question whether the linear headache (LH) we reported be a linear interictal pain in epicranial fugax (EF), based on a case they reported. We think that the LH is not a linear interictal pain in EF based on our observations and considerations.

ABSTRACT

Postpartum visits (PPVs) are still underutilized in rural China, and identification of factors that influence PPV use is important in ensuring the utilization of maternal health services and for wellbeing of women. A cross-section study was undertaken to collect related data from 347 rural women interviewed six weeks or more after delivery, and an ANOVA was performed to find whether there were significant differences in the number of PPVs among different rural areas in China. According to Andersen's socio-behavioral model of health service use, factors were divided into equitable and inequitable ones. Chi-squared test, univariate and multiple analyses were used to determine the equity of PPV use by identifying factors that were most strongly associated with the use of a PPV. The results showed that 20.2% of the respondents (n=70) did not receive any PPVs, and 62.5% (n=173) of those who had PPVs (n=277) did not receive standard PPVs (referring to at least 3 visits). There was no significant difference among different rural areas in terms of the number of PPVs (F=1.514, P=0.211). Multiple regression analyses revealed that enabling factors such as compensation for delivery expense [OR (95% CI)=2.825 (1.331, 5.995)], village type [OR (95% CI)=1.802 (1.021, 3.182)] and service quality [OR (95% CI)=1.847 (1.074, 3.176)] were strongly associated with PPV use. Both enabling factors such as home visits [OR (95% CI)=1.855 (1.085, 3.174)], service quality [OR (95% CI)=1.993 (1.155, 3.439)] and need factors such as low birth weight [OR (95% CI)=4.424 (1.482, 13.203)] were significantly associated with standard PPV use. Our results suggested that the equitable access to PPVs has been considerably improved in rural areas in China. The associations between inequitable factors and PPV use warrant further exploration, and policies aimed at improving quality and patterns of service supply are needed in order to ensure a full equitable access to maternal health services.

ABSTRACT

BACKGROUND: A headache circumscribed in a line-shaped area but not confined to the territory of one particular nerve had ever been described in Epicrania Fugax (EF) of which the head pain is moving and ultrashort. In a 25-month period from Feb 2012 to Mar 2014, we encountered 12 patients with a paroxysmal motionless head pain restricted in a linear trajectory. The head pain trajectory was similar to that of EF, but its all other features obviously different from those of EF. We named this distinctive but undescribed type of headache linear headache (LH). METHODS: A detailed clinical feature of the headache was obtained in all cases to differentiate with EF, trigeminal autonomic cephalalgias (TACs) and cranial neuralgia. Similarities and differences in clinical features were compared between LH and migraine. RESULTS: The twelve LH patients (mean age 43.9 ± 12.2) complained of a recurrent, moderate to severe, distending (n = 9), pressure-like (n = 3) or pulsating (n = 3) pain within a strictly unilateral line-shaped area. The painful line is distributed from occipital or occipitocervical region to the ipsilateral eye (n = 5), forehead (n = 6) or parietal region (n = 1). The pain line has a trajecory similar to that of EF but no characteristics of moving. The headache duration would be ranged from five minutes to three days, but usually from half day to one day in most cases (n = 8). Six patients had the accompaniment of nausea with or without vomiting, and two patients had the accompaniment of ipsilateral dizziness. The attacks could be either spontaneous (n = 10) or triggered by noise, depression and resting after physical activity (n = 1), or by stress and staying up late (n = 1). The frequency of attacks was variable. The patients had well response to flunarizine, sodium valproate and amitriptyline but not to carbamazepine or oxcarbazepine. LH is different from EF, trigeminal autonomic cephalalgias (TACs) and cranial neuralgia, but it had couple of features similar to that of migraine. CONCLUSIONS: The clinical picture of LH might be a subtype of migraine, or represent a novel syndrome.

ABSTRACT

Recurrent painful ophthalmoplegic neuropathy (RPON), formerly named ophthalmoplegic migraine (OM), is a rare condition characterized by the association of unilateral headaches and the ipsilateral oculomotor nerve palsy. The third cranial nerve is most commonly involved in the recurrent attacks. But it is still debated whether a migraine or an oculomotor neuropathy may be the primary cause of this disorder. Here, we report an elder patient who had a recurrent ophthalmoplegia starting with an unilateral headache circumscribed in an area shaped in a line linking the posterior-parietal region and the ipsilateral eye. And the headache had couple of features similar to that of migraine, such as past history of recurrent migraine attacks, accompaniments of nausea, vomiting, and phonophobia, response to flunarizine and sodium valproate. We may herein report a subtype of OM but not a RPON. This case report indicates that OM may exist as an entity and some OM may be wrongly grouped under the category of RPON in the current international headache classification.

ABSTRACT

To construct a recombinant expression plasmid Bacmid-P1-3CD containing the P1 and 3CD genes of enterovirus 71(EV71), the P1 and 3CD genes were cloned into the same baculovirus shuttle vector (Bacmid). Recombinant AcMNPV-P1-3CD was obtained by transfecting the Bacmid-P1-3CD into the insect cell line of S f9. With the IFA and Western-blot methods for identification of expression products confirmed that the target protein was expressed in interior of infected S f9 cells. Electron microscopy showed that the structural protein capsid P1 was cut by virus-encoded protease 3CD and assembled into EV71 virus like particles (VLPs) about 27nm diameter. Different values of MOI and time points of expression were compared to explore the optimal expression condition, and the results showed that the time point could be a more important factor. Then we used S f9 cells with serum-free medium in CellSTACK-10 Culture Chambers to produce EV71 VLPs in the confirmed condition. After purification of VLPs by density gradient centrifugation, we observed on SDS-PAGE profile the purified sample contained three major proteins whose molecular masses corresponded to those of VP1 (39kD), VP0 (34kD) and VP3 (26kD) as well as the intact structure, which can be greatly used for further study in protein structure and genetic engineering vaccine research.

ABSTRACT

The nonviral gene delivery system is an attractive alternative to cancer therapy. A new kind of gelatin-silica nanoparticles (GSNPs) was developed through a two-step sol-gel procedure. To improve the transfection efficacy, GSNPs modified with different fusion peptides (Tat, HA2, R8, Tat/HA2, and Tat/R8) were prepared for particle size, zeta potential, cellular uptake, hemolysis activity at physiological pH (7.0) or acidic pH (5.0), and condensation of plasmid DNA. The results suggest that the sizes and zeta potentials of GS-peptide conjugates were 147 - 161 nm and 19 - 33 mV, respectively; GS-peptide conjugates exhibited low cytotoxicity; the plasmid DNA was readily entrapped at a GS-peptide/pDNA weight ratio of 50 - 200. The in vitro and in vivo studies demonstrated that the synergistic effects of cell-penetrating peptide Tat and fusogenic peptide HA2 could promote the efficient cellular internalization, endosome escape, and nucleus targeting, hence delivering the therapeutic nucleic acid efficiently.
