Fire-needle moxibustion (FNM) is an ancient method of external therapy that combines acupuncture with moxibustion, and has the property of high temperature resistance. Insomnia is a major public health problem and strongly associated with a high prevalence, impact on daily life, comorbidity with other disorders, and societal costs. The clinical practice demonstrates that FNM has a therapeutic effect on insomnia. Here we will provide a protocol to evaluate the effectiveness and safety of FNM for insomnia.

Bone marrow-mesenchymal stem cells (BM-MSCs) possess immunomodulatory properties in the brain. However, it remains unclear whether intravenously transplanted BM-MSCs have a neuromodulator effect on the activation of microglias after ischemic stroke. This study aimed to investigate the immunomodulatory effect of BM-MSCs on the regulation of brain microglial inactivation during the acute phase of stroke.

Background: Alpha-enolase is an important glycolytic enzyme, and its aberrant expression has been associated with multiple tumor progression. However, few studies investigated the expression of alpha-enolase and its clinical significance in pancreatic cancer (PC). Objectives: To evaluate alpha-enolase level in PC tissues by immunohistochemical (IHC) analysis, and investigate the association of alpha-enolase expression with clinicopathologic features. Methods: The alpha-enolase levels in pancreatic cancer tissues were analyzed by using the Oncomine database. The expression of alpha-enolase, Ki67 and p53 in pancreatic cancer and adjacent normal tissues were evaluated by IHC using the corresponding primary antibodies on the commercial tissue arrays. We also examined their association with clinicopathologic parameters, and explored their prognostic value in PC. Results: We identified an elevation of alpha-enolase mRNA level in pancreatic cancer independent datasets from Oncomine. IHC analysis showed that alpha-enolase protein levels were elevated in 47% (n=100) PC tissue samples, but there was weak or no staining in the normal tissues. Statistical analysis revealed that high levels of alpha-enolase were significantly associated with Stage and Lymph node metastasis. Correlation analysis indicated that over-expression of alpha-enolase was positively associated with Ki67 expression and inversely correlated with p53 expression. Furthermore, membranous expression of alpha-enolase was also observed in 29.8% (14/47) total alpha-enolase positive samples, and was significantly associated with Lymph node metastasis. Kaplan-Meier survival analysis demonstrated that high total alpha-enolase expression was significantly associated with unfavorable survival, while membranous alpha-enolase expression was significantly associated with better survival of PC patients. Multivariate Cox analysis demonstrated that total alpha-enolase expression was an independent prognostic factor for PC patients. Conclusions: Our results suggested that alpha-enolase level was significantly elevated in pancreatic cancer tissues, which was closely associated with PC progression. It might be a candidate target for targeted pancreatic cancer treatments.

Increasing evidence has demonstrated that the secretion of cytokines may be associated with cigarette smoke-induced immunomodulatory effects, but a comprehensive analysis of the cytokine profile for cigarette smoke condensate (CSC) exposure is lacking. The aims of this study were to (1) examine the release of 20 cytokines induced by CSC from 12 brands of cigarettes in macrophages cells (Ana-1) and (2) to investigate the general characteristics of the immunomodulatory effects of CSC. Luminex technology was used to simultaneously determine the levels of 20 cytokines (interleukin (IL)-1α, IL-1β, IL-2, IL-4, IL-5, IL-6, IL-10, IL-12, IL-13, IL-17, granulocyte-macrophage colony-stimulating factor (GM-CSF), interferon-γ (IFN-γ), keratinocyte-derived Chemokine (KC), monocyte chemoattractant protein 1 (MCP-1), macrophage inflammatory protein 1α (MIP-1α), induced protein 10 (IP-10), tumor necrosis factor α (TNF-α), vascular endothelial growth factor (VEGF), monkine inducible by γ interferon (MIG), and fibroblast growth factor (FGF)-basic) in the supernatants from Ana-1 cells treated with the CSC. The results showed that the release of eight cytokines was altered (IL-5, IL-6, IL-12, TNF-α, VEGF, IP-10, MCP-1, and MIP-1α) compared with the control. These cytokines fall into two major subtypes: proinflammatory cytokines, including IL-5, IL-6, IL-12, TNF-α, and VEGF, and chemokines, including IP-10, MCP-1, and MIP-1α. Compared with control, the remaining 12 cytokines were not significantly affected by CSC from the 12 brands of cigarettes. As a general characteristic, CSC exerts potently suppressive immunomodulatory effects on cytokine production of Ana-1 cells. Proinflammatory cytokines and chemokines may account for or contribute to the immunosuppressive properties of CSC.

The present study developed an oral hepatocyte growth factor (HGF) gene therapy strategy for gastric ulcers treatment. An attenuated Salmonella typhimurium that stably expressed high HGF (named as TPH) was constructed, and the antiulcerogenic effect of TPH was evaluated in a rat model of gastric ulcers that created by acetic acid subserosal injection. From day 5 after injection, TPH (1 × 10⁹ cfu), vehicle (TP, 1 × 10⁹ cfu), or sodium bicarbonate (model control) was administered orally every alternate day for three times. Then ulcer size was measured at day 21 after ulcer induction. The ulcer area in TPH-treated group was 10.56 ± 3.30 mm², which was smaller when compared with those in the TP-treated and model control groups (43.47 ± 4.18 and 56.25 ± 6.38 mm², respectively). A higher level of reepithelialization was found in TPH-treated group and the crawling length of gastric epithelial cells was significantly longer than in the other two groups (P < 0.05). The microvessel density in the ulcer granulation tissues of the TPH-treated rats was 39.9 vessels/mm², which was greater than in the TP-treated and model control rats, with a significant statistical difference. These results suggest that TPH treatment significantly accelerates the healing of gastric ulcers via stimulating proliferation of gastric epithelial cells and enhancing angiogenesis on gastric ulcer site.

This study examined the significance of macrophage autophagy in extracellular matrix metalloproteinase inducer (EMMPRIN)-mediated atherosclerosis (AS). Apolipoprotein E-deficient (ApoE-/-) mice were fed a western diet to establish an AS model. EMMPRIN and p62/Sequestosome-1(SQSTM1) expression were evaluated in plaque macrophages from the AS mice using immunofluorescence. The EMMPRIN and p62/SQSTM1 protein expression levels in macrophages increased with the increasing vulnerability of the atherosclerotic plaques. RAW264.7 cells and ApoE-/- mice Bone Marrow-derived macrophages were transfected with different small interfering RNAs (siRNAs) or plasmids, or treated with different drugs in the presence or absence of oxidized low-density lipoprotein (oxLDL). The protein levels of the targets were evaluated using western blotting (WB), and the autophagosomes were observed under a transmission electron microscope (TEM). Over-expressed EMMPRIN dramatically inhibited oxLDL-mediated autophagy. EMMPRIN also negatively regulated autophagy primarily through the nuclear factor-kappa B (NF-κB) signalling pathway. In turn, activated NF-κB up-regulated EMMPRIN expression. Inhibition of EMMPRIN decreased cell apoptosis and the release of inflammatory cytokines via the promotion of macrophage autophagy. Infection with an adenovirus delivering the EMMPRIN-siRNA ameliorated AS, promoted macrophage autophagy in plaques and reduced the serum TNF-α, IL-6, MCP-1 and NF-κB expression levels in the AS mice. Chloroquine (CQ) reversed these effects. This study revealed for the first time that the feedback loop of the "EMMPRIN/NF-κB" pathway plays an important role in atherosclerotic plaques via modulation of autophagy in macrophages, which might provide a potential strategy for the clinical treatment of AS.

Mitochondrial dysfunction has been implicated in the pathogenesis of Parkinson's disease (PD). Carboxyl terminus of Hsp70-interacting protein (CHIP) is a key regulator of mitochondrial dynamics, and mutations in CHIP or deficits in its expression have been associated with various neurological diseases. This study explores the protective role of CHIP in cells and murine PD models. In SH-SY5Y cell line, overexpression of CHIP improved the cell viability and increased the ATP levels upon treatment with 1-methyl-4-phenylpyridinium (MPP+). To achieve CHIP overexpression in animal models, we intravenously injected mice with AAV/BBB, a new serotype of adeno-associated virus that features an enhanced capacity to cross the blood-brain barrier. We also generated gene knock-in mice that overexpressed CHIP in neural tissue. Our results demonstrated that CHIP overexpression in mice suppressed 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced damage, including movement impairments, motor coordination, and spontaneous locomotor activity, as well as loss of dopaminergic neurons. In vitro and in vivo experiments showed that overexpression of CHIP inhibited the pathological increase in Drp1 observed in the PD models, suggesting that CHIP regulates Drp1 degradation to attenuate MPP+/MPTP-induced injury. We conclude that CHIP plays a protective role in MPP+/MPTP-induced PD models. Our experiments further revealed that CHIP maintains the integrity of mitochondria.

Spinocerebellar ataxia type 3 (SCA3) is a dominantly inherited neurodegenerative disease caused by a CAG repeat expansion in the region of the ATXN3 gene. The main feature of SCA3 is progressive ataxia, which affects balance, gait, and speech. Urine cells (UCs) of a SCA3 patient were successfully translated to induced pluripotent stem cells (iPSCs) by using the Sendai virus delivery system. ZZUi004-A cell line may provide a robust platform for further study of SCA3 pathogenesis as well as drug testing and gene therapy research.

Oculopharyngodistal myopathy (OPDM) is an autosomal dominant adult-onset degenerative muscle disorder characterized by ptosis, ophthalmoplegia and weakness of the facial, pharyngeal and limb muscles. Trinucleotide repeat expansions in non-coding regions of LRP12, G1PC1, NOTCH2NLC and RILPL1 were reported to be the etiologies for OPDM.

Fucosylated glycosaminoglycans (FGs) derived from sea cucumbers exhibit potent intrinsic Xase (iXase) inhibition, anticoagulation, and antithrombosis. Plasma activated partial thromboplastin time (APTT), a widely used screening test worldwide, is crucial for evaluating anticoagulant efficacy. However, the applicability of these commercially available APTT reagents for assessing anticoagulation of FGs remains unreported. In this study, we investigated the disparity between ellagic acid and colloidal silica APTT reagents in evaluating anticoagulation of dHG-5 and dHLFG-4, two depolymerized FGs, and elucidated the underlying rationale. The results demonstrated that dHG-5 and dHLFG-4 exhibited heightened sensitivity to the ellagic acid APTT reagent both in vitro and in vivo, and did not significantly affect the activation of APTT reagents for plasma. In addition, both ellagic acid and colloidal silica APTT reagents inhibited the anti-iXase of dHG-5 and dHLFG-4, and the inhibition of the ellagic acid APTT reagent was less pronounced compared to the colloidal silica APTT reagent. These findings suggest that the reduced impact of the ellagic acid APTT reagent on the anti-iXase activity of dHG-5 and dHLFG-4 is responsible for the increased sensitivity in plasma APTT analysis. This study offers valuable insights into the characteristics of two APTT reagents applied for assessing the anticoagulant activity of FG-related compounds.

Overwhelming evidence points to that genetic factors contributing to the development of Alzheimer's disease (AD) and Parkinson's disease (PD). Genome-Wide Association Study (GWAS) has come a long way in the last decade. So far, a large number of GWAS studies have been published on neurological diseases and many other diseases, providing us with a wealth of genetic information and unique biological insights.

Background. Carboxypeptidase A4 (CPA4) belongs to a member of the metallocarboxypeptidase family, and its expression in lung cancer samples and clinical significance are still not investigated until now. In this study, we aimed to evaluate the level of CPA4 in non-small-cell lung cancer (NSCLC) samples and correlate its level with clinical outcome. Methods. CPA4 gene expression in lung cancer tissues were analyzed by using the Oncomine database (www.oncomine.org). The expression of CPA4, Survivin and VEGF in lung cancer and adjacent normal tissues were evaluated by IHC using the corresponding primary antibodies on two different commercial tissue arrays (Shanghai Biochip Co., Ltd., Shanghai, China). Their levels in serum were determined by using commercial human enzyme-linked immunosorbent assay kits. We also examined their relations to clinicopathologic parameters, and explored the diagnostic and prognostic value in NSCLC. Results. We identified an elevation of CPA4 in mRNA level and gene amplification in lung cancer tissues in comparison to normal lung tissues. High CPA4 expression was observed in 120/165 (72.7%) NSCLC samples, and significantly correlated with Tumor size, Depth of invasion, Lymph Node Metastasis, Stage, VEGF level and Survivin level. High CPA4 expression is associated with poor prognosis of NSCLC patients. Multivariable Cox regression analysis demonstrated that CPA4 expression was an independent prognostic factor. Furthermore, serum CPA4 level was also significantly higher in NSCLC patients than in healthy controls. Logistic regression analysis revealed that serum CPA4 and CYFRA21-1 level were the significant parameters for detecting NSCLC. Receiver operating characteristic curves (ROC) in NSCLC patients versus normal people yielded the optimal cut-off value was 2.70 ng/ml for CPA4 and 19 ng/ml for CYFRA21-1, respectively. The area under ROC curve (AUC) was 0.830 for the combination of the two tumor markers. Conclusion. Our results demonstrated that overexpression of CPA4 in NSCLC is associated with an unfavorable prognosis, and serum CPA4 level combining with serum CYFRA21-1 level could be used to aid early detection of NSCLC.

Aberrant microenvironment and endoplasmic reticulum (ER) stress are associated with solid-tumor progression. Stress proteins, like heat shock proteins and glucose-regulated proteins, are frequently overexpressed in human tumors. It has been reported that derlin-1 is involved in ER stress response. In vitro studies have demonstrated that derlin-1 participates in the retrotranslocation of misfolded proteins from ER into the cytosol. Because the roles of derlin-1 in human cancer have not yet been characterized, we investigated the expression of derlin-1 in human breast carcinoma and whether it protected cancer cells against ER stress-induced apoptosis.

Several SLC20A2 mutations have been implicated as potential causes of Fahr's disease, a subtype of primary familial brain calcification (PFBC), but very few patient-derived induced pluripotent stem cell (iPSC) models have been established. We have identified a novel SLC20A2 mutation in a family with Fahr's disease. We subsequently obtained dermal fibroblasts from a patient in this family. These fibroblasts were successfully transformed into iPSCs by employing episomal plasmids expressing OCT3/4, SOX2, KLF4, LIN28, and L-MYC. Our approach offers a resource and a platform for further research into the mechanism of Fahr's disease and could facilitate development and screening of pharmaceutical and gene therapies.

MEOX2 mutation has been reported as a potential cause of familial Alzheimer's disease. Recently, a novel MEOX2 mutation was identified in a family with Alzheimer's disease. The dermal fibroblasts of the patient were obtained and successfully transformed into induced pluripotent stem cells (iPSCs), employing episomal plasmids expressing OCT3/4, SOX2, KLF4, LIN28, and L-MYC. Our model may offer a good platform for further research on the pathomechanism, drug testing, and gene therapy of this disease.

Intrinsic Xase (iXase), the last and rate-limiting enzyme complex in the intrinsic coagulation pathway, may be an ideal target for antithrombotic treatment. A depolymerized fraction of fucosylated glycosaminoglycan from sea cucumber Holothuria fuscopunctata, dHG-5 (Mw 5.2 kDa), showed potent and selective inhibition of iXase (IC50, 14 nM). In this work, the series of oligosaccharides contained in dHG-5 were purified and their precise structures were confirmed by 2D NMR and MS spectra. The relationships between anti-iXase, f.IXa-binding, anticoagulant and antithrombotic activities (y) and molecular weight (x) could be approximately expressed as the power function (y = a × xb), and these activity potencies of dHG-5 were approximately equivalent to the weighted average sum of that of its oligosaccharides. Given the prominent pharmacological properties, well-defined chemical composition and explicable relationships between dHG-5 and its oligosaccharides in pharmacological behaviors, dHG-5 is expected to be an ideal novel anticoagulant medicine.

Skin fibroblasts were obtained from a 42-year-old Alzheimer's disease (AD) patient carrying mutations in the PSEN1 gene. An iPSC line was successfully established using the Sendai-virus (SeV) delivery system. The patient-specific iPSCs were free of genomically integrated reprogramming genes, had the specific mutation, expressed the expected pluripotency markers, and had the potential to differentiate into cells of all three germ layers. Our model might offer a robust platform for further study of the pathomechanism of this disease as well as drug testing and gene therapy studies.

This work evaluated the improvement of curdlan production of Agrobacterium sp. ATCC 31749 by using culture medium containing juice of discarded bottom part of green Asparagus spear (MJDA). Curdlan production was carried out using Agrobacterium sp. ATCC 31749 in flasks with different volumes of MJDA and its non-juice-adding control (CK) incubated in shaker at 30 °C, 200 rpm rotation for 168 h.

Fire needle therapy is an ancient external treatment method of traditional Chinese medicine. This therapy is simple to operate and has fewer side effects. Gouty arthritis (GA) is common disease that is often characterized by high excruciating pain on joint. Evidence from clinical studies show that fire needle exerts therapeutic effects on gout arthritis, but no evidence-based medicine is available. This study aimed to evaluate the efficacy and safety of fire acupuncture in the treatment of gout arthritis.

We aimed to explore the active ingredients and molecular mechanism of Tripterygium wilfordii (TW) in the treatment of diabetic nephropathy (DN) through network pharmacology and molecular biology. First, the active ingredients and potential targets of TW were obtained through the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and related literature materials, and Cytoscape 3.7.2 software was used to construct the active ingredient-target network diagram of TW. Second, the target set of DN was obtained through the disease database, and the potential targets of TW in the treatment of DN were screened through a Venn diagram. A protein interaction network diagram (PPI) was constructed with the help of the String platform and Cytoscape 3.7.2. Third, the ClueGO plug-in tool was used to enrich the GO biological process and the KEGG metabolic pathway. Finally, molecular docking experiments and cell pathway analyses were performed. As a result, a total of 52 active ingredients of TW were screened, and 141 predicted targets and 49 target genes related to DN were identified. The biological process of GO is mediated mainly through the regulation of oxygen metabolism, endothelial cell proliferation, acute inflammation, apoptotic signal transduction pathway, fibroblast proliferation, positive regulation of cyclase activity, adipocyte differentiation and other biological processes. KEGG enrichment analysis showed that the main pathways involved were AGE-RAGE, vascular endothelial growth factor, HIF-1, IL-17, relaxin signalling pathway, TNF, Fc epsilon RI, insulin resistance and other signaling pathways. It can be concluded that TW may treat DN by reducing inflammation, reducing antioxidative stress, regulating immunity, improving vascular disease, reducing insulin resistance, delaying renal fibrosis, repairing podocytes, and reducing cell apoptosis, among others, with multicomponent, multitarget and multisystem characteristics.
