Abstract
We reported a case of 73-year-old male with multiple pulmonary nodules and cavities. The patient was admitted with a chief complaint of "dry cough with shortness of breath for 3 months". Chest CT showed multiple irregular masses, nodules, and patchy lesions in both lungs, accompanied by the formation of cavities. He also had anemia and renal dysfunction. Despite given empirical anti-infective and anti-tuberculosis treatments, the pulmonary nodules progressed, and the cavities enlarged. Anti-neutrophil cytoplasmic antibodies (ANCA) were negative twice. Bronchoscopic biopsy was performed. The mucosal pathology of the right middle lobe lesion showed little necrosis, focal granulomatous structure formation, and relevant vasculitis and remaining vessel wall structure in the necrosis lesions by elastic fiber staining. A clinical diagnosis of ANCA-negative necrotizing granulomatous polyangiitis was made and the patient was treated with glucocorticoids and cyclophosphamide. The nodules and cavities shrank, and some lesions were absorbed.

Abstract
Arid habitats have recently attracted increasing attention in terms of biodiversity research and the discovery of new bacterial species. These habitats are among the target ecosystems suitable for isolating new strains of actinobacteria that are likely to produce new metabolites. This paper presents the results on the isolation of actinobacteria from soils of the dry steppe zone of the Selenga Highlands, the characterization of their taxonomic diversity, as well as ecological and trophic properties. The bacterial counts on ISP 4 medium ranged from 6.6 × 105 to 7.1 × 106 CFU/g. The highest bacterial counts were observed in the subsurface and middle horizons of the studied soils. 28 strains of Gram-positive bacteria represented by thin-branched mycelium, coccoid and bacilliform forms were isolated. According to the results of 16S rRNA gene analysis, the isolated strains were representatives of Streptomyces, Arthrobacter, Glycomyces, Kocuria, Microbacterium, Micromonospora, Nocardioides, Pseudarthrobacter, and Rhodococcus (Actinomycetota). One isolate that showed low 16S rRNA gene sequence similarity with previously isolated and validly described species was a new species of the genus Glycomyces. It was shown that all tested strains are mesophilic, prefer neutral or slightly alkaline conditions, have growth limits in the temperature range of 5-45 °C and pH 6-9. The optimal NaCl concentration for growth of most strains was 0-1 %. The strains under study were capable of utilizing a wide range of mono- and disaccharides and polyatomic alcohols as a carbon source. The isolated strains were capable of using both organic (proteins and amino acids) and inorganic (ammonium salts and nitrates) compounds as nitrogen sources. The examinations of extracellular enzymes showed that all isolates were capable of producing catalase and amylase; 78.6 % of the total number of isolates produced protease and lipase; 53.6 %, cellulase; and 28.6 %, urease. The data obtained expand current knowledge about the diversity of microbial communities in soils of the Selenga Highlands and also confirm the potential of searching for new actinobacteria species in these soils.

Abstract
Objective: To evaluate the efficacy and safety of selective genicular artery embolization for the treatment of the knee pain secondary to osteoarthritis. Methods: From October 2020 to July 2021, 17 patients (23 knees) aged (68±7) years with moderate to severe knee pain secondary to knee osteoarthritis were prospectively included in the General Hospital of Ningxia Medical University. There were 6 males and 11 females included in this research. Patients were assessed with knee pain, stiffness, and function with the Visual Analogue Scale (VAS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) at baseline, using the Kellgren-Lawrence (K-L) grading to evaluate the severity of KOA, and using the Magnetic Resonance Knee Osteoarthritis Score (MOAKS) to evaluate the MR imaging characteristics of the affected knee. Selective genicular artery embolization (GAE) was performed in all patients. The patients were followed up for 6 months after the procedure. Patients were assessed with the VAS score and WOMAC scale at 1 d, 1 week and 1, 3 and 6 months after the procedure to evaluate the clinical outcomes, including the improvement of knee joint pain, stiffness and function, as well as the occurrence of adverse reactions. Results: Three to seven genicular artery branches were superselected and embolized in 23 knees, and 4 to 7 genicular artery branches were embolized in 7 patients with K-L grade 4. The clinical improvement was 95.6% (22/23) at 1 month, 86.9% (20/23) at 3 months, and 91.3% (21/23) at 6 months. Twenty-three knees completed the 6-month follow-up, and the VAS score, WOMAC pain score, and total WOMAC score at 1, 3, and 6 months after surgery were (2.5±1.3), (3.4±2.4), and (19.7±9.8) points, (3.0±1.8), (4.5±3.4), and (22.3±11.3) points, (2.8±1.5), (4.1±3.0), and (20.5±11.0) points, which were lower than the (6.6±0.9), (11.4±2.6) and (47.0±12.0) points at baseline (all P<0.001). During the follow-up period, 7 patients had adverse reactions: 3 cases had skin ecchymosis in the femoral artery puncture area, 4 cases had knee joint stiffness and pain within 1 day after operation, which were relieved spontaneously in 1 week, 6 patients had joint clicking during extension and flexion activities after operation, of which 3 cases subsided spontaneously within 3 months after operation. None of the patients had major procedure-related adverse events. Conclusion: GAE has a high clinical improvement rate and a low incidence of adverse reactions in the treatment of the pain secondary to knee osteoarthritis, which provides a new treatment option for patients who fail to respond to conservative treatment.

Abstract
Introduction Thyroid cancer is a familiar kind of cancer. Natural products are promising therapeutic approaches in treating thyroid cancer. Triptolide is a diterpenoid epoxide extracted from Tripterygium wilfordii. The mechanism of triptolide in the treatment of thyroid cancer has not been investigated clearly. Methods We evaluated triptolide targets and thyroid cancer targets with related databases. The protein–protein interaction (PPI) networks of the triptolide targets and thyroid cancer targets were constructed with Cytoscape software. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses of the core PPI network were obtained. Molecular docking analysis was used to evaluated the binding of triptolide with core targets. Furthermore, apoptosis assays, real-time polymerase chain reaction (RT-PCR) and Western blotting were used to evaluate the anticancer functions of triptolide. Results Triptolide had 34 targets, and thyroid cancer had 210 targets. The core PPI network of merged PPI networks had 164 nodes and 4513 edges. GO and KEGG enrichment analyses showed that triptolide were related to the cell cycle, apoptosis, and inflammatory signaling pathways. Molecular docking analysis showed that triptolide directly reacted with four core targets: cyclin-dependent kinase inhibitor 1A (CDKN1A), c-JUN, RELA, and tumor protein p53 (TP53). CB-Dock analysis indicated that triptolide could stably bind to core targets. Triptolide inhibited the growth but induced apoptosis of thyroid cancer cells. Triptolide increased the mRNA expression of CDKN1A and TP53 but reduced the mRNA expression of c-JUN and RELA, as shown by RT-PCR. Triptolide increased the protein levels of CDKN1A and phospho-p53 but reduced those of phospho-c-JUN and phospho-NF-κB p65, as shown by Western blotting. Discussion We considered that triptolide could treat thyroid cancer by inhibiting cell proliferation, inducing apoptosis and inhibiting inflammatory pathways such as the NF-κB and MAPK signaling pathways. CDKN1A, c-JUN, RELA, and TP53 were involved in the antithyroid cancer mechanism of triptolide.

Abstract
Based on the new mission of public health set in the Healthy China strategy and the insufficient response to COVID-19, this article pointed out the problems of the current public health and preventive medicine system from the macro-system level, meso-organization level, and micro-individual level, including insufficient strategic planning, resource input, institutional coordination, talent training and team building. It was creatively proposed that a disease prevention and control bureau should be set up outside the health commission to implement the vertical management at four levels, from national level to province-level, including autonomous region, municipality directly under the central government, city-level and district/county-level. The disease prevention and control bureau should consist of a strategic research institute, a center for disease prevention and control (CDC), a human resources training base, and a scientific research institute, which could perform their own duties and rely on each other. Enhancing the functions of strategic planning, overall coordination, and evidence-based decision-making in the original system, emphasizing the foresight and continuity of scientific research, and allowing the CDC to focus more on health management and emergency response could better facilitate in protecting the public health, improving the health and quality of life of the entire population, and guaranteeing the social stability and development.

Abstract
Colorectal cancer (CRC) is a common malignant tumor that affects people worldwide. Metagenomic analyses have shown an enrichment of Fusobacterium nucleatum (F. nucleatum) in colorectal carcinoma tissue; many studies have indicated that F. nucleatum is closely related to the colorectal carcinogenesis. In this review, we provide the latest information to reveal the related molecular mechanisms. The known virulence factors of F. nucleatum promote adhesion to intestinal epithelial cells via FadA and Fap2. Besides, Fap2 also binds to immune cells causing immunosuppression. Furthermore, F. nucleatum recruits tumor-infiltrating immune cells, thus yielding a pro-inflammatory microenvironment, which promotes colorectal neoplasia progression. F. nucleatum was also found to potentiate CRC development through toll-like receptor 2 (TLR2)/toll-like receptor 4 (TLR4) signaling and microRNA (miRNA)-21 expression. In addition, F. nucleatum increases CRC recurrence along with chemoresistance by mediating a molecular network of miRNA-18a*, miRNA-4802, and autophagy components. Moreover, viable F. nucleatum was detected in mouse xenografts of human primary colorectal adenocarcinomas through successive passages. These findings indicated that an increased number of F. nucleatum in the tissues is a biomarker for the diagnosis and prognosis of CRC, and the underlying molecular mechanism can probably provide a potential intervention treatment strategy for patients with F. nucleatum-associated CRC.

Abstract
OBJECTIVE To study the types and characteristics of TUBB1 mutation in children with congenital hypothyroidism (CH) and thyroid dysgenesis (TD) in Shandong, China. METHODS Mutations of the whole coding region of the TUBB1 gene were analyzed for 289 children with CH and TD in Shandong. Whole-genome DNA was extracted from peripheral blood leukocytes. PCR multiplication was performed for the whole coding region of the TUBB1 gene. Sanger sequencing was performed for the PCR products, and a biological information analysis was performed. RESULTS Among the 289 children with CH and TD, 4 (1.4%) were found to have a c.952C>T(p.R318W) heterozygous mutation in the TUBB1 gene, resulting in the change of tryptophan into arginine at codon 318 of TUBB1 protein. This mutation was evaluated as "potentially pathogenic" based on the classification criteria and guidelines for genetic variation by American College of Medical Genetics and Genomics. CONCLUSIONS A novel mutation is detected in the exon of the TUBB1 gene in children with CH and TD in Shandong, suggesting that the TUBB1 gene may be a candidate pathogenic gene for CH children with TD.

Abstract
Current cancer therapies have encountered adverse response due to poor therapeutic efficiency, severe side effects and acquired resistance to multiple drugs. Thus, there are urgent needs for finding new cancer-targeted pharmacological strategies. In this review, we summarized the current understanding with THZ1, a covalent inhibitor of cyclin-dependent kinase 7 (CDK7), which demonstrated promising anti-tumor activity against different cancer types. By introducing the anti-tumor behaviors and the potential targets for different cancers, this review aims to provide more effective approaches to CDK7 inhibitor-based therapeutic agents and deeper insight into the diverse tumor proliferation mechanisms.

Abstract
Children with severe pneumonia often have heart failure. This study explored the clinical effect of high quality nursing intervention on children with pneumonia complicated with heart failure. In the study, 96 children with pneumonia complicated with heart failure were selected and randomly divided into a conventional nursing group (n=48) and a high quality nursing group (n=48). Based on the conventional nursing, the children in one group were given high quality nursing, and comprehensive nursing was carried out in aspects such as respiratory tract, medication, psychology and diet. Then, the heart rate, respiratory rate, heart failure correction time, hospitalization time, cost and nursing satisfaction were compared between the two groups. The results showed that the heart rate of the high quality nursing group was 145.37±8.72 times/min and the respiratory rate was 45.65±6.08 times/min, which were significantly lower than those of the conventional nursing group (P less than 0.05). The correction time of heart failure was about 32 h in the high quality nursing group, and the length and cost of hospitalization were significantly lower than those in the conventional nursing group (P less than 0.05). The nursing satisfaction of the patients' family members in the high quality nursing group was also higher (P less than 0.05). This study shows that high quality nursing can promote the recovery of children with pneumonia complicated with heart failure, and is worth popularizing widely in clinics.

Abstract
Myasthenia gravis (MG) is an autoimmune neuromuscular disorder, affecting the quality of life of millions of people worldwide. The present study aims to determine the relationship between micro-RNA-143 (miR-143) and C-X-C motif chemokine 13 (CXCL13) and whether it influences the pathogenesis of myasthenia gravis (MG). Thymus specimens were resected from patients with thymic hyperplasia combined with MG and then infused into normal mouse cavities to establish MG mouse models. Immunohistochemistry, reverse transcription-quantitative PCR, in situ hybridization detection, and Western blot analysis were employed to identify the expression of miR-143 and CXCL13 in MG and normal mice. The obtained thymocytes were cultured in vitro and transfected with a series of miR-143 mimic, miR-143 inhibitor, overexpression of CXCL13, or siRNA against CXCL13. MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] and flow cytometry assays were employed to assess cell viability, cycle entry, and apoptosis of the thymocytes. Dual-luciferase reporter assay provided verification, confirming that CXCL13 was the target gene of miR-143. Low miR-143 expression in the thymus tissues of the MG mice was detected, which presented with a reciprocal relationship with the expression rate of CLCX13. Observations in relation to the interactions between miR-143 mimic or siRNA-CXCL13 exposure showed reduced cell viability, with a greater number of cells arrested at the G0/G1 phase and a greater rate of induced apoptosis. Furthermore, overexpression of CXCL13 rescued miR-143 mimic-induced apoptosis. The findings have identified the potential role of miR-143 as a MG development mediator by targeting CXCL13. The key results obtained provide a promising experimental basis for targeted intervention treatment with miR-143.

Abstract
BACKGROUND/AIMS Parkinson's disease (PD) is a neurodegenerative movement disease with a high annual incidence. Accumulating evidence demonstrates that microRNAs play important roles in the pathogenesis of multiple neurological disorders, including PD. This study aims to investigate how microRNA-200a (miR-200a) regulates striatal dopamine receptor D2 (DRD2) to affect apoptosis of striatum in rats with PD and to explore the associated mechanism. METHODS After successfully establishing a PD model by 6-hydroxydopamine injections, PD rats were mainly treated with miR-200a mimics, inhibitors, Forskolin or a combination of miR-200a inhibitors and Forskolin. High-performance liquid chromatography-electrochemical detection (HPLC-ECD) was employed to detect the levels of dopamine, 3, 4-dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA), and chemistry colorimetric methods were applied to detect the levels of malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). A TUNEL assay and immunocytochemical staining were performed to observe apoptosis and tyrosine hydroxylase (TH)-positive cells in the striatum. The expression of miR-200a, DRD2, Bad, Bax, Bcl-2, cAMP and PKA was determined by reverse transcription quantitative polymerase chain reaction (RT-qPCR) and western blot assays. RESULTS In the cellular experiments, after transfection with the inhibitor of miR-200a, decreased levels of Bax, GSH-Px, SOD, dopamine, DOPAC and HVA but increased levels of MDA and Bcl-2 were found along with a reduced apoptosis rate and increased TH-positive cell number. In addition, downregulating miR-200a resulted in lower expression of AKT, cAMP and PKA but higher expression of DRD2 and CREB, indicating that the downregulation of miR-200a increases DRD2 expression, which blocks the cAMP/PKA signaling pathway. CONCLUSION This study provides evidence that the inhibition of miR-200a can repress apoptosis in the striatum via inhibition of the cAMP/PKA signaling pathway by upregulating DRD2 expression in PD rats.

Abstract
Glioma is known to be the most prevalent primary brain tumor. In recent years, there has been evidence indicating myeloid cell leukemia-1 (MCL1) plays a role in brain glioblastoma. Therefore, the present study was conducted with aims of exploring the ability of MCL1 silencing to influence glioma cell senescence and apoptosis through the mediation of the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway. Glioma and tumor-adjacent tissues were collected in order to detect the presence of higher levels of MCL1 protein expression. Next, the mRNA and protein expression of MCL1, PI3K, Akt, B cell lymphoma 2 (Bcl2), Bcl2-associated X (Bax), B lymphoma Mo-MLV insertion region 1 homolog (Bmi-1), and phosphatase and tensin homolog (PTEN) were determined. Cell counting kit-8 assay was applied to detect cell proliferation, β-galactosidase staining for cell senescence, and flow cytometry for cell cycle entry and apoptosis. Initially, the results revealed higher positive expression rate of MCL1 protein, increased mRNA and protein expression of MCL1, PI3K, Akt, Bmi-1, and Bcl-2 and decreased that of Bax and PTEN in human glioma tissues. The silencing of MCL1 resulted in a decrease in mRNA and protein expression of PI3K, Akt, Bmi-1, and Bcl-2 and an increase in Bax and PTEN expressions in glioma cells. Moreover, silencing of MCL1 also inhibited cell proliferation and cell cycle entry in glioma cells, and promoted glioma cell senescence and apoptosis. In conclusion, the aforementioned results collectively suggested that the silencing of MCL1 promotes senescence and apoptosis in glioma cells through inhibiting the PI3K/Akt signaling pathway. Thus, decreasing the expression of MCL1 might have therapeutic functions in glioma. © 2018 IUBMB Life, 71(1):81-92, 2019.

Abstract
Purpose: Gastric cancer is mainly treated by gastrectomy, the results of which were unsatisfactory without any adjuvant treatments. This study aimed to examine the performance of radiotherapy, chemotherapy, and chemoradiotherapy after surgery in order to acquire the optimal adjuvant treatment. Method: Embase and PubMed were retrieved to conduct a systematic research. Hazard ratios (HR) of overall survival (OS) and progression-free survival (PFS) as outcomes were calculated by synthesizing direct and indirect evidence to evaluate the efficacy of three treatments against surgery alone. The P-score ranking was utilized to rank the therapies. Consistency was assessed by heat plot. Begg's test was performed to evaluate publication bias. Results: A total of 35 randomized controlled studies (RCTs) with 8973 patients were included in our network meta-analysis (NMA). As for efficacy outcomes, OS and PFS of 1, 2, 3, and 5 years, all revealed chemoradiotherapy (CRT) as the best of three adjuvant therapies. Meanwhile, P-score ranking results also displayed that CRT was the optimal regimen. Additionally, radiotherapy (RT) and chemotherapy (CT) were two alternative options following CRT since RT performed well in short-term survival while CT could improve the long-term survival. Conclusion: CRT was the most recommended therapy to accompany surgery according to our results. However, no analysis about the safety of these three treatments was mentioned in our study. Further studies including safety outcomes were required to draw a more comprehensive conclusion.

Abstract
BACKGROUND/AIMS Spinal cord glioma is a highly aggressive malignancy that commonly results in high mortality due to metastasis, high recurrence and limited treatment regimens. This study aims to elucidate the effects of long non-coding RNA LINC01260 (LINC01260) on the proliferation, migration and invasion of spinal cord glioma cells by targeting Caspase recruitment domain family, member 11 (CARD11) via nuclear factor kappa B (NF-κB) signaling. METHODS The Multi Experiment Matrix (MEM) website was used for target gene prediction, and the DAVID database was used for analysis of the relationship between CARD11 and the NF-κB pathway. In total, 60 cases of glioma tissues and adjacent normal tissues were collected. Human U251 glioma cells were grouped into blank, negative control (NC), LINC01260 vector, CARD11 vector, siRNA-LINC01260, siRNA-CARD11, LINC01260 vector + CARD11 vector and LINC01260 + siRNA-CARD11 groups. A dual-luciferase reporter assay was conducted to verify the target relationship between LINC01260 and CARD11. Reverse transcription quantitative polymerase chain reaction (RT-qPCR) and western blot analysis were employed to assess expression of LINC01260, E-cadherin, p53, CARD11, Ki67, N-cadherin, matrix metalloproteinase (MMP)-9, NF-κBp65 and NF-κBp50. MTT, flow cytometry, wound-healing and Transwell assays were performed to examine cell viability, the cell cycle, apoptosis, invasion and migration. Tumor growth was assessed through xenografts in nude mice. RESULTS CARD11 was confirmed to be a target gene of LINC01260 and was found to be involved in regulating the NF-κB pathway. Compared with adjacent normal tissues, glioma tissues showed reduced expression of LINC01260 and elevated expression of CARD11 and genes related to apoptosis, invasion and migration; activation of NF-κB signaling was also observed. In contrast to the blank and NC groups, an elevated number of cells arrested in G1 phase, increased apoptosis and reduced cell proliferation, invasion and number of cells arrested in S and G2 phases, as well as tumor growth were found for the LINC01260 vector and siRNA-CARD11 groups. CONCLUSIONS Our findings demonstrate that overexpression of LINC01260 inhibits spinal cord glioma cell proliferation, migration and invasion by targeting CARD11 via NF-κB signaling suppression.

Abstract
Background/Aims: MiRNAs are involved in phenotype modulation of neural cells after peripheral nerve injury. However, the roles of miRNAs on the survival of dorsal root ganglion (DRG) neurons have not yet been fully understood. Methods: In this study, the expression of miR-142-3p was measured in rat DRGs (L4-L6) during the initial 24 hours post sciatic nerve transection by microarray profiling and quantitative PCR. The functional assays including the cell viability, colony formation, cell cycle and apoptosis assays were performed in miR-142-3p mimic or inhibitor transfected cell lines. Results: MiR-142-3p was identified to be siginificantly upregulated in rat DRGs (L4-L6) during the initial 24 hours post sciatic nerve transection. MiR-142-3p mimic enhanced cell viability by promoting cell cycle and inhibiting cell apoptosis in cultured DRG neurons. In addition, cyclin-dependent kinase inhibitor 1B (CDKN1B, also known as p27/Kip1) and tissue inhibitor of metalloproteinase 3 (TIMP3) were identified as targets of miR-142-3p. Furthermore, knockdown of CDKN1B or TIMP3 by specific siRNAs could reverse the effect of miR-142-3p. Conclusions: In the conclusion, the results showed that miR-142-3p could promote neuronal cell cycle and inhibit apoptosis at least partially through suppressing CDKN1B and TIMP3 after peripheral nerve injury.

Abstract
Background/Aims: Parkinson’s disease (PD) is the second most common neurodegenerative disease after Alzheimer’s disease, and recent studies suggested that oxidative stress (OS) contributes to the cascade that leads to dopamine cell degeneration in PD. In this study, we hypothesized that salidroside (SDS) offers protection against OS injury in 6-hydroxydopamine (6-OHDA) unilaterally lesioned rats as well as the underlying mechanism. Methods: SDS and LiCl (activators of the Wnt/β-catenin signaling pathway) administration alone and in combination with 6-OHDA injection in rats was performed 3 days before modeling for 17 consecutive days to verify the regulatory mechanism by which SDS affects the Wnt/β-catenin signaling pathway as well as to evaluate the protective effect of SDS on PD in relation to OS in vivo. In addition, pheochromocytoma 12 (PC12) cells were incubated with 10 µmol/L SDS or LiCl alone or with both in combination for 1 h followed by a 24-h incubation with 100 µmol/L 6-OHDA to obtain in vitro data. Results: In vivo the administration of LiCl was found to ameliorate behavioral deficits and dopaminergic neuron loss; increase superoxide dismutase (SOA) activity, glutathione peroxidase (GSH-Px) levels, and glycogen synthase kinase 3β phosphorylation (GSK-3β-Ser9); reduce malondialdehyde (MDA) accumulation in the striatum and the GSK-3β mRNA level; as well as elevate β-catenin and cyclinD1 mRNA and protein levels in 6-OHDA-injected rats. This SDS treatment regimen was found to strengthen the beneficial effect of LiCl on 6-OHDA-injected rats. In vitro LiCl treatment decreased the toxicity of 6-OHDA on PC12 cells and prevented apoptosis. Additionally, LiCl treatment increased SOA activity, GSH-Px levels, and GSK-3β-Ser9 phosphorylation; decreased MDA accumulation in the striatum and GSK-3β mRNA levels; as well as increased β-catenin and cyclinD1 mRNA and protein levels in 6-OHDA-treated PC12 cells. Additionally, SDS treatment increased the protective effect of LiCl on 6-OHDA-treated PC12 cells. Conclusion: Evidence from experimental models suggested that SDS may confer neuroprotection against the neurotoxicity of 6-OHDA in response to OS injury and showed that these beneficial effects may be related to regulation of the Wnt/β-catenin signaling pathway. Therefore, SDS might be a potential therapeutic agent for treating PD.

Abstract
Diabetes often causes learning and memory deficits, which leads to unfavorable behavioral performance. In this study, we investigated the effects of long non-coding RNA (lncRNA) ANRIL on learning, memory abilities, and hippocampal neuronal apoptosis via the NF-κB signaling pathway in streptozotocin (STZ)-induced diabetic rats. After successful establishment of diabetic rat models, the subjects were then assigned into the DM, DM + si-ANRIL, DM + si-negative control (si-NC) groups, as well as an additional normal group. Morris water maze test was employed to assess behavioral performance of rats, followed by the recording of body weight and blood glucose levels. Expressions of ANRIL, NF-κB signaling pathway-related, and apoptosis-related genes were examined by qRT-PCR and western blotting. Rat hippocampus expression levels of cleaved-caspase-3 were determined by immunofluorescence. Cell apoptosis was examined by TUNEL assay. Versus to the normal group, revealed there to be activation of the NF-κB signaling pathway, decreased weight, increased blood glucose, increased escape latency, reduced residence time, memory impairment, increased cleaved-caspase-3 expression, and increased apoptosis were detected in the DM and DM + si-NC groups. The DM + si-ANRIL group exhibited inhibited NF-κB signaling pathway, weight loss, decreased blood glucose, recovered memory, decreased cleaved-caspase-3 expression and reduced apoptosis compared to the DM group, with higher weight of rats, lower blood glucose levels, and stronger memory abilities in the DM + si-ANRIL group. Taken together, these findings indicate that silencing lncRNA ANRIL promotes memory recovery and decreases hippocampal neurons apoptosis in diabetic rats through the inhibition of the NF-κB signaling pathway.

Abstract
The present study was to investigate the effect of lncRNA LINC00880 targeting CACNG5 on cell proliferation, migration, invasion, and apoptosis in spinal cord ependymoma (SCE) through the MAPK signaling pathway. GEO database was used to download gene expression data related with SCE (GSE50161 and GSE66354) and annotation file. LncRNA with differential expression was predicted by Multi Experiment Matrix website (MEM). The target gene was analyzed by KEGG pathway enrichment analysis. SCE tissues and adjacent tissues were collected. The positive expression of CACNG5 protein was tested by immunohistochemistry. Expression of LINC00880, CACNG5, and MAPK signaling pathway-related proteins was measured with qRT-PCR and Western blotting. Cell proliferation, migration, invasion, cycle, and apoptosis were detected using MTT, Transwell assay, Scratch test, and Flow cytometry. SCE tissues showed increased LINC00880 expression. CACNG5 was a target gene of LINC00880 and correlated with MAPK signaling pathway. Compared with adjacent tissues, SCE tissues showed lower positive expression of CACNG5. Compared with the blank group, LINC00880 expression was higher in the LINC00880 vector and LINC00880 vector + CACNG5 vector groups, and lower in the si-LINC00880 and si-LINC00880 + si-CACNG5 groups; in the LINC00880 vector and si-CACNG5 groups, expression of survivin, p38MAPK, ERK1/2, JNK1/2/3 increased and CACNG5 and Bax expression reduced, the proliferation, invasion and migration of tumor cells increased, and apoptosis rate decreased. Opposite results were found in the si-LINC00880 and CACNG5 vector groups. The findings indicate that lncRNA LINC00880 targeting CACNG5 inhibits cell apoptosis and promotes proliferation, migration, and invasion in SCE through the MAPK signaling pathway.

Abstract
Epilepsy is a group of neurological disorders characterized by epileptic seizures. In this study, we aim to explore the role of microRNA-421 (miR-421) in hippocampal neurons of epilepsy mice via the TLR/MYD88 pathway. Forty mice were randomly served as the normal and model (established as epilepsy model) groups. Hippocampal neurons were assigned into seven groups with different transfections. The RT-qPCR and western blotting were conducted to examine the expression of miR-421 TLR2, TLR4, MYD88, Bax, Bcl-2, p53, Beclin-1, and LC3II/LC3I. Cell proliferation and apoptosis were detected by MTT and flow cytometry.MYD88 is a target gene of miR-421. Model mice showed elevated expression of TLR2, TLR4, MYD88, Bax, p53, Beclin-1, and LC3II/LC3I but reduced expression of miR-421 and Bcl-2. In vitro experiments reveals that overexpression of miR-421 inhibited the TLR/MYD88 pathway. Besides, overexpressed miR-421 declined cell apoptosis but increased cell proliferation. It reveals that miR-421 targeting MYD88 could inhibit the apoptosis and autophagy of hippocampal neurons in epilepsy mice by down-regulating the TLR/MYD88 pathway.

Abstract
Hypoxia–ischaemia (HI) remains a major cause of foetal brain damage presented a scarcity of effective therapeutic approaches. Dexmedetomidine (DEX) and microRNA‐140‐5p (miR‐140‐5p) have been highlighted due to its potentially significant role in the treatment of cerebral ischaemia. This study was to investigate the role by which miR‐140‐5p provides cerebral protection using DEX to treat hypoxic–ischaemic brain damage (HIBD) in neonatal rats via the Wnt/β‐catenin signalling pathway. The HIBD rat models were established and allocated into various groups with different treatment plans, and eight SD rats into sham group. The learning and memory ability of the rats was assessed. Apoptosis and pathological changes in the hippocampus CA1 region and expressions of the related genes of the Wnt/β‐catenin signalling pathway as well as the genes responsible of apoptosis were detected. Compared with the sham group, the parameters of weight, length growth, weight ratio between hemispheres, the rate of reaching standard, as well as Bcl‐2 expressions, were all increased. Furthermore, observations of increased levels of cerebral infarction volume, total mortality rate, response times, total response duration, expressions of Wnt1, β‐catenin, TCF‐4, E‐cadherin, apoptosis rate of neurons, and Bax expression were elevated. Following DEX treatment, the symptoms exhibited by HIBD rats were ameliorated. miR‐140‐5p and si‐Wnt1 were noted to attenuate the progression of HIBD. Our study demonstrates that miR‐140‐5p promotes the cerebral protective effects of DEX against HIBD in neonatal rats by targeting the Wnt1 gene through via the negative regulation of the Wnt/β‐catenin signalling pathway.

Abstract
Objective: To identify the prevalence of sleep problems in children with autism spectrum disorder (ASD) and to explore the association with the main melatonin metabolite, 6-sulfatoxymelatonin (6-SM). Method: This was a prospective case-control study. Children with ASD were recruited from Child Development and Behavioral Research Center (CDBRC) of the Harbin Medical University and Harbin Special Education School from October 2015 to April 2017 (ASD group) . Healthy controls were selected from five kindergartens and one primary school in Harbin by the stratified cluster random sampling (control group) . The Children's Sleep Habits Questionnaire (CSHQ) was used to investigate the sleep problems of the two groups. The patients were matched in a 1∶1 ratio for the age and sex, and the urine samples of case-control pairs were collected in the morning. The level of 6-SM was measured by the enzyme linked immunosorbent assay (ELISA). The student's t test was used for comparison between the ASD group and control group, and the Pearson correlation analysis was used to determine the correlation difference. Result: A total of 212 ASD children (mean (±SD) age was (6.0±2.7) years, and 181 patients (85.4%) were male), and a total of 334 healthy children(mean (±SD) age was (5.9±2.6) years, and 272 patients (81.4%) were male) were recruited. Among them, 101 matched case-control pairs completed the collection of urine samples. According to the statistical analysis, the scores of total CSHQ, bedtime resistance, sleep onset delay, sleep duration, night waking, parasomnia, sleep disordered breathing and daytime sleepiness in children with ASD were significantly higher than those in the control group (48.2±6.2 vs. 46.6±5.4, 11.4±2.5 vs. 10.7±2.8, 1.7±0.8 vs. 1.5±0.7, 4.1±1.4 vs. 3.7±1.1, 4.2±1.5 vs. 3.8±1.1, 8.5±1.5 vs. 8.3±1.4, 3.7±1.0 vs. 3.4±0.8, 11.7±2.5 vs. 12.4±2.7, t=3.16, 3.00, 3.23, 2.76, 3.19, 1.99, 3.45,-2.72, P=0.002, 0.003, 0.001, 0.006, 0.002, 0.048, 0.001, 0.007), the level of 6-SM was significantly lower in children with ASD than that of healthy controls ((1.24±0.50) vs. (1.68±0.63)μg/h, t=-5.50, P<0.01), and the total CSHQ score was negatively correlated with the level of 6-SM (r=-0.50, P<0.01). Conclusion: The children with ASD were at high risk for sleep problems, and the melatonin metabolite of ASD group was abnormal compared with that of the control group. Moreover, there was a negative correlation between the severity of sleep problems and the level of 6-SM in ASD children. The results of our study indicate that the abnormal melatonin metabolism may be one of the causes of sleep problems in children with ASD.

Abstract
Previous studies suggested that lower vitamin D might be a risk factor for autism spectrum disorders (ASDs). The aim of this study was to estimate the prevalence of ASDs in 3-year-old Chinese children and to examine the association between neonatal vitamin D status and risk of ASDs. We conducted a study of live births who had taken part in expanded newborn screening (NBS), with outpatient follow-up when the children 3-year old. The children were confirmed for ASDs in outpatient by the Autism Diagnostic Interview-Revised and Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 criteria. Intellectual disability (ID) status was defined by the intelligence quotient (IQ < 80) for all the participants. The study design included a 1:4 case to control design. The concentration of 25-hydroxyvitamin D3 [25(OH)D3] in children with ASD and controls were assessed from neonatal dried blood samples. A total of 310 children were diagnosed as having ASDs; thus, the prevalence was 1.11% (95% CI, 0.99% to 1.23%). The concentration of 25(OH)D3 in 310 ASD and 1240 controls were assessed. The median 25(OH)D3 level was significantly lower in children with ASD as compared to controls (p < 0.0001). Compared with the fourth quartiles, the relative risk (RR) of ASDs was significantly increased for neonates in each of the three lower quartiles of the distribution of 25(OH)D3, and increased risk of ASDs by 260% (RR for lowest quartile: 3.6; 95% CI, 1.8 to 7.2; p < 0.001), 150% (RR for second quartile: 2.5; 95% CI, 1.4 to 3.5; p = 0.024), and 90% (RR for third quartile: 1.9; 95% CI, 1.1 to 3.3; p = 0.08), respectively. Furthermore, the nonlinear nature of the ID-risk relationship was more prominent when the data were assessed in deciles. This model predicted the lowest relative risk of ID in the 72rd percentile (corresponding to 48.1 nmol/L of 25(OH)D3). Neonatal vitamin D status was significantly associated with the risk of ASDs and intellectual disability. The nature of those relationships was nonlinear. © 2017 American Society for Bone and Mineral Research.

Abstract
The human gastro-intestinal tract is not only the habitat of gut microbiota, but also the main place that the body gets available nutrients. Therefore, the gut microbiota of human can be inseparable associated with the human nutrition. The common technologies used among gut microbiota research included metageonomic, metatranscriptomics, metaproteomics, and metabolomics. The research of gut microbiota based on above omics methods confirmed that diets were the main factors influencing the composition and expression of gut microbiota. The proportion, quantity, stable state, and metabolic changes of gut microbiota were closely related to obesity, diabetes mellitus, cardiovascular disease, and other nutritional-related diseases. Reasonable dietary intervention can adjust the disorders of gut microbiota, which can achieve prevention and treatment of obesity, diabetes, cardiovascular diseases, and other nutritional-related diseases. Although the single omics methods can be used to study the problems of some aspects of gut microbiota, the combination of multi-omics is needed to achieve the above objectives.

Abstract
This network meta-analysis compared the short-term and long-term efficacies of first-line chemotherapy regimens in patients with advanced colorectal cancer (CRC). The 10 regimens included folinic acid + 5-fluorouracil + oxaliplatin (FOLFOX), folinic acid + 5-fluorouracil + irinotecan (FOLFIRI), folinic acid + 5-fluorouracil + gemcitabine (FFG), folinic acid + 5-fluorouracil + trimetrexate (FFT), folinic acid + 5-fluorouracil (FF), irinotecan + oxaliplatin (IROX), raltitrexed + oxaliplatin (TOMOX), folinic acid + tegafur-uracil (FTU), raltitrexed, and capecitabine. Electronic searches were performed in the Cochrane Library, PubMed and Embase databases from inception to June 2017. Network meta-analysis combined direct and indirect evidence to obtain odds ratios (ORs) and surface under the cumulative ranking curves (SUCRA) of different chemotherapy regimens for advanced CRC. Fourteen randomized controlled trails (RCTs) covering 4,383 patients with advanced CRC were included. The results revealed that FOLFOX, FOLFIRI, IROX, and TOMOX all showed higher overall response rates (ORRs) than FF or raltitrexed. Compared with raltitrexed, the aforementioned four regimens also had higher 1-year progression-free survival (PFS) rates. In addition, FOLFOX and FOLFIRI exhibited higher disease control rates (DCRs) and 1-year PFS rates than FF or raltitrexed. Cluster analysis revealed that FOLFOX, FOLFIRI, and TOMOX had better short-term and long-term efficacies. These findings suggest FOLFOX, FOLFIRI, and TOMOX are superior to other regimens for advanced CRC. These three regimens are therefore recommended for clinical treatment of advanced CRC.

Abstract
We investigated the involvement of microRNA-433 (miR-433) in the proliferation, migration, and invasiveness of oral squamous cell carcinoma (OSCC). Totally 108 OSCC tissues and adjacent normal tissues from patients with OSCC were collected. Also, transplanted tumor formation experiment in nude mice was conducted to verify the effect of miR-433 and FAK on subcutaneous transplanted tumor. The CD44+ stem cell from SCC-9 were collected and assigned into the blank, miR-433 mimics, mimics control, miR-433 inhibitors, inhibitors control, siFAK and miR-433 inhibitors + siFAK groups. The qRT-PCR and western blotting were used to detect miR-433, FAK, ERK, MEK, pERK and pMEK after transfection. Flow cytometry, MTT assay, scratch test and Transwell assay were performed to determine the cell proportion, growth, migration and invasion of SCC-9 cells. In cell line SCC-9, expression of CD133, Oct-4, and BIM-1 was greater in CD44+ cells than CD44- cells, indicating that CD44+ cells had characteristics of tumor stem cells. Expression of FAK, ERK, MEK, p-ERK and p-MEK was decreased in tumor tissues from the CD44-, miR-433, and siFAK groups. Expression of MiR-433 mRNA was elevated, while levels of FAK, ERK, MEK, p-ERK, and p-MEK mRNA were all decreased in the miR-433 mimics group. In the miR-433 mimics and siFAK groups, cell proliferation, migration, and invasion were all decreased, while the opposite trends were seen in the miR-433 inhibitor group. These results indicate that miR-433 downregulates FAK through the ERK/MAPK signaling pathway to inhibit the proliferation, migration, and invasiveness of SCC-9 OSCC cells.

Abstract
Our previous work showed that purple sweet potato colour (PSPC), a class of naturally occurring anthocyanins, effectively improved hepatic glucose metabolic dysfunction in high-fat-diet (HFD)–treated mice. This study investigated the effects of PSPC on HFD-induced hepatic steatosis and the signalling events associated with these effects. Mice were divided into 4 groups: control group, HFD group, HFD+PSPC group, and PSPC group. PSPC was administered daily for 20 weeks at oral doses of 700 mg/(kg·day)−1). Our results showed that PSPC significantly improved obesity and related metabolic parameters, as well as liver injury in HFD-treated mice. Moreover, PSPC dramatically attenuated hepatic steatosis in HFD-treated mice. PSPC markedly prevented oxidative stress-mediated Src activation in HFD-treated mouse livers. Furthermore, PSPC feeding remarkably suppressed mitogen-activated protein kinase kinase/extracellular-signal-regulated kinase (MEK/ERK) signalling and consequent CCAAT/enhancer binding protein β (C/EBPβ) activation and restored AMPK activation in HFD-treated mouse livers, which was confirmed by U0126 treatment. Ultimately, PSPC feeding dramatically reduced protein expression of FAS and CD36 and the activation of ACC, and increased the protein expression of CPT1A in the livers of HFD-treated mice, indicating decreased lipogenesis and fatty acid uptake and enhanced fatty acid oxidation. In conclusion, PSPC exhibited beneficial effects on hepatic steatosis, which were associated with blocking Src and C/EBPβ activation.

Abstract
The aim of this study was to investigate the correlation of expression of IGF1R-RACK1-STAT3 and Bcl-xl in nasopharyngeal carcinoma (NPC) with the clinicopathological features and the prognosis of NPC. Our study selected 215 NPC tissues and 178 chronic nasopharyngitis tissues (control group). Positive expression rates of IGF1R, RACK1, STAT3, and Bcl-xl were tested by immunohistochemical method, and expression of IGF1R, RACK1, STAT3, Bcl-xl, Bcl-2, and Bax by western blotting. Correlation of IGF1R, RACK1, STAT3, and Bcl-xl with the clinicopathological features of NPC was analyzed. The correlation among those four expression was analyzed by Spearman. The survival of NPC and independent factors of prognosis were tested by Kaplan-Meier and COX proportional hazards model respectively. The NPC group had higher positive expression rates of IGF1R, RACK1, STAT3, and Bcl-xl, and elevated expression of IGF1R, RACK1, STAT3, Bcl-xl, Bcl-2, and Bax. The lymph node metastasis (LNM) group had higher positive expression rates of IGF1R and RACK1 when compared with the non-LNM group. Patients with stage III and IV had higher positive expression rates of IGF1R, RACK1, STAT3, and Bcl-xl. There was positive correlation between expression of IGF1R and RACK1, STAT3. Such correlation was found between RACK1 and STAT3. Patients with negative expression of IGF1R, RACK1, STAT3, and Bcl-xl had higher survival rates. The risky factors of poor prognosis of NPC were positive expression of IGF1R, RACK1, STAT3 and Bcl-xl, and LNM. IGF1R-RACK1-STAT3 and Bcl-xl expression correlated with the clinicopathological features and poor prognosis of NPC.

Abstract
Graves' disease is an autoimmune process in which the thyroid gland is triggered by autoantibodies, resulting in hyperthyroidism. The purpose of the present study is to elucidate whether exon-1 49 A/G and promoter region 318C/T polymorphisms in the CTLA-4 gene. This study consisted of 653 eligible patients with Graves' disease. After receiving 131I radionuclide therapy, these patients were classified into the remission and non-remission groups. A logistic regression-based model was used to analyze independent factors affecting the patient response to 131I radionuclide therapy. The results showed that CTLA-4 49 A/G was closely related to the efficacy of 131 I treatment for Graves' disease (AG + GG vs. AA: OR = 6.543, 95%CI = 2.611 ∼ 16.40, P < 0.001; G vs. A: OR = 3.482, 95%CI = 2.457 ∼ 4.934, P < 0.001). Moreover, the findings revealed that haplotype A-C (P < 0.001, OR = 3.592, 95%CI: 2.451 ∼ 5.262) and G-C (P < 0.001, OR = 0.282, 95%CI: 0.204 ∼ 0.391) were associated with the efficacy of 131 I therapy in treating Graves' disease. Logistic regression analysis indicated that thyroid weight (OR = 0.963, 95%CI = 0.944 ∼ 0.982, P < 0.001) and CTLA-4 exon-1 49 A/G polymorphism (OR = 0.334, 95%CI = 0.233 ∼ 0.478, P < 0.001) independently affect the efficacy of 131 I therapy in Graves' disease. These data indicated that CTLA-4 exon-1 49 A/G polymorphism may be associated with patient response to radionuclide 131 I therapy in Graves' disease.

Abstract
Recently, there has been as enhanced interest on global level to recognize the potent antioxidant compounds which are pharmacologically active with less or no side effects. Thus, the current investigation was intended to scrutinize the protective effect of indirubin on the cardiac marker, such as, enzymes, LDH isoenzyme, cardiac troponin-T (cTnT), antioxidant enzymes marker and lipid peroxidation (LPO) in response of isoproterenol (ISO)-induced myocardial infarction (MI) in Wistar rats. The experimental animals were categorized into following groups: Group I received saline; Group II received Indirubin (10 mg/kg); Group III received ISO (100 mg/kg) and Group IV received ISO + indirubin (10 mg/kg) for continuous 10 days. The ISO induced MI injury was confirmed via enhanced level of enzymes markers viz., creatine kinase-MB, creatine kinase, lactate dehydrogensae, troponin-T, alanine transaminase (ALT) and aspartate transaminase (AST) in the rats serum. The enhanced expression of LDH (1 and 2) isoenzyme bands were also observed in the ISO induced MI rats. We have also estimated the level of LPO in the heart and plasma, which was found to be significantly (P<0.05) improved. Moreover, the marker of enzymatic antioxidant enzymes viz., glutathione reductase (GRx), catalase (CAT), glutathione-S-transferase (GST), glutathione peroxidase (GPx) and superoxide dismutase (SOD) in the heart, and the level of non-enzymatic antioxidant marker viz., vitamin (C, E) in heart and serum were found to be considerably (P<0.05) reduced in the ISO induced MI in Wistar rats. Whereas, the ISO control Wistar rats showed significant (P<0.05) increase in the uric acid level in the plasma. The Indirubin treated rats confirmed the significant protective effect via modulation of all biological and antioxidant parameters tested. The result of the investigation was further found in agreement of the histopathological studies of the indirubin treated rats which clearly showed recovery from the myocardial infarction. Thus, on the basis of that, it has been suggested that indirubin showed protection of myocardial tissues against the ISO persuaded oxidative stress.

Abstract
Introduction:
Intra-arterial therapy (IAT) for large vessel occlusions strokes (LVOS) has been increasingly utilized. The benefit of endovascular reperfusion in patients with mid-range ASPECTS remains to be established.
Materials and methods:
Retrospective analysis of LVOS patients with ASPECTS 5-7 treated with IAT (n=86) or medical therapy alone (±IV t-PA; n=15) at two academic centers from 2009-2012. Definitions employed: Symptomatic ICH: any parenchymal hematoma; Successful reperfusion: modified TICI≥2B; Good and acceptable clinical outcomes: 90-day mRS 0-2 and 0-3, respectively. Final infarct volumes were calculated based on 24-hour post-procedure CT or MRI scans.
Results:
Mean age (67±14 vs. 67±19 years) and baseline NIHSS (20±5 vs. 20±6) were similar in the IAT and medical treatment groups. Successful reperfusion was achieved in 58 (67%) IAT patients. Symptomatic and asymptomatic ICH occurred in 9 (10%) and 31 (36%) IAT patients, respectively. The IAT rates of 90-day good and acceptable outcomes were 20% (17/86) and 33% (28/86), respectively. Successful reperfusion in IAT patients was associated with smaller FIV (p=0.015) and higher rates of good (p=0.02) and acceptable (p=0.03) outcomes. The median final infarct volume was significant lower with IAT vs. medical therapy (80ml [IQR, 38-122] vs. 190ml [121-267], p=0.015). There was a strong trend towards a higher hemicraniectomy requirement in medically vs. endovascularly treated patients (20% versus 6%, p=0.06) despite similar in-hospital mortality (20% versus 26.7 %, p=0.75).
Conclusions:
Despite a low probability of achieving functional independence, IAT in LVOS patients with ASPECTS 5-7 appears to result in smaller final infarct volumes leading to a reduction in the need for hemicraniectomy and decreasing the degree of overall disability. Therefore, it may be a reasonable option for patients and families who favor a shift from severe to moderate disability. Prospective studies utilizing shift in outcome measures are warranted to confirm these results.

Abstract
BACKGROUND 12(S)-Hydroxyeicosatetraenoic acid (12(S)-HETE) is a metabolite of arachidonic acid. 12(S)-HETE is involved in the pathogenesis of atherosclerosis and diabetes. However, the correlation between 12(S)-HETE and coronary artery disease (CAD) in the diabetic patient is unclear. AIMS The study investigated the relationship between 12(S)-HETE and CAD in Type 2 diabetes (T2D). METHODS Plasma 12(S)- HETE levels were detected by enzyme-linked immunosorbent assay in 103 healthy controls (control), 109 diabetic patients without CAD (diabetic), and 152 diabetic patients with CAD (diabetic-CAD). RESULTS 12(S)-HETE levels were higher in both diabetic and diabetic-CAD groups compared to control and in the diabetic-CAD group compared to the diabetic group. In the multiple linear stepwise regression analysis, 12(S)-HETE levels correlated independently with CAD, systolic blood pressure, and glycated hemoglobin. CONCLUSIONS These results indicate that 12(S)-HETE levels are increased in diabetic patients with CAD, suggesting a role for atherosclerosis in T2D.

Abstract
AIMS/HYPOTHESIS Increased inflammation and oxidative stress are associated with insulin resistance (IR) and metabolic disorders. Serum histidine levels are lower and are negatively associated with inflammation and oxidative stress in obese women. The objective of this study was to evaluate the efficacy of histidine supplementation on IR, inflammation, oxidative stress and metabolic disorders in obese women with the metabolic syndrome (MetS). METHODS A total of 100 obese women aged 33-51 years with BMI ≥ 28 kg/m² and diagnosed with MetS were included following a health examination in the community hospital in this randomised, double-blinded, placebo-controlled trial. Participants were allocated to interventions by an investigator using sequentially numbered sealed envelopes and received 4 g/day histidine (n = 50) or identical placebo (n = 50) for 12 weeks. Participants then attended the same clinic every 2 weeks for scheduled interviews and to count tablets returned. Serum histidine, HOMA-IR, BMI, waist circumference, fat mass, serum NEFA, and variables connected to inflammation and oxidative stress were measured at baseline and 12 weeks. Participants, examining physicians and investigators assessing the outcomes were blinded to group assignment. In addition, the inflammatory mechanisms of histidine were also explored in adipocytes. RESULTS At 12 weeks, a total of 92 participants completed this trail. Compared with the placebo group (n = 47), histidine supplementation significantly decreased HOMA-IR (-1.09 [95% CI -1.49, -0.68]), BMI (-0.86 kg/m² [95% CI -1.55, -0.17]), waist circumference (-2.86 cm [95% CI -3.86, -1.86]), fat mass (-2.71 kg [95% CI -3.69, -1.73]), serum NEFA (-173.26 μmol/l [95% CI -208.57, -137.94]), serum inflammatory cytokines (TNF-α, -3.96 pg/ml [95% CI -5.29, -2.62]; IL-6, -2.15 pg/ml [95% CI -2.52, -1.78]), oxidative stress (superoxide dismutase, 17.84 U/ml [95% CI 15.03, 20.65]; glutathione peroxidase, 13.71 nmol/ml [95% CI 9.65, 17.78]) and increased serum histidine and adiponectin by 18.23 μmol/l [95% CI 11.74, 24.71] and 2.02 ng/ml [95% CI 0.60, 3.44] in histidine supplementation group (n = 45), respectively. There were significant correlations between changes in serum histidine and changes of IR and its risk factors. No side effects were observed during the intervention. In vitro study indicated that histidine suppresses IL6 and TNF mRNA expression and nuclear factor kappa-B (NF-κB) protein production in palmitic acid-induced adipocytes in a dose-dependent manner, and these changes were diminished by an inhibitor of NF-κB. CONCLUSIONS/INTERPRETATION Histidine supplementation could improve IR, reduce BMI, fat mass and NEFA and suppress inflammation and oxidative stress in obese women with MetS; histidine could improve IR through suppressed pro-inflammatory cytokine expression, possibly by the NF-κB pathway, in adipocytes.

Abstract
OBJECTIVE To investigate the psychological characteristics of hepatic malignancy patients before interventional procedures and assess associations with related factors. METHODS Two hundred and thirteen patients requiring interventional procedure for hepatic malignancy were asked to complete a survey of health knowledge and psychological symptom on health knowledge questionnaire and SCL-90 before interventional procedure. Logistic regression analysis was employed to determine the association of various demographic, clinical and health knowledge factors with the presence of psychological symptoms in patients. RESULTS Eight psychological symptom scores, i.e. somatization, obsessive-compulsive tendencies, depression, anxiety, hostility, phobia, paranoid ideations and psychotic states, were significantly higher than the normal range (P< 0.001). Of 213 cases in the study, 49 families (23.00%) concealed the diagnoses of hepatic carcinoma from patients; 135 patients (63.38%) described the prognosis of the disease correctly. It was demonstrated that the correlations between psychological symptoms and related factors, i.e. age, gender, education, interventional procedure times and health knowledge, were statistically significant (P< 0.05). CONCLUSION Psychological distress is severe in hepatic malignancy patients before interventional procedures. Age, gender, education, interventional procedure times and health knowledge are associated with psychological symptoms which are significant different from the normal range in Chinese.

Abstract
Bone marrow stromal cells (BMSCs) play critical roles in repairing endothelium damage. However, the mechanisms underlying BMSC differentiation into vascular endothelial cells (VECs) is not well understood. We aimed to find new factors involved in this process by exploiting a novel chemical inducer in a gene microarray assay. We first identified a novel benzoxazine derivative (6-amino-2,3-dihydro-3-hydroxymethyl-1,4-benzoxazine; ABO) that can induce BMSC differentiation to VECs in a capillary-like tube formation assay, promote analysis of endothelial cell-specific marker expression, and facilitate uptake of 1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate-acetylated low-density lipoprotein (Dil-Ac-LDL). Microarray analysis of BMSCs treated with ABO for 4 h revealed changes in only a handful of genes. The only one upregulated was homeobox-containing 1 (Hmbox1) gene, whereas six genes, including IP-10 and others, were downregulated. The upregulation of Hmbox1 and downregulation of IP-10 were confirmed by RT-PCR, quantitative PCR (qPCR), and Western blot analysis. It is reported that IP-10 could suppresse EC differentiation into capillary structures. In this study ABO could not induce BMSC differentiation to VECs in the presence of IP-10. Small interfering RNA knockdown of Hmbox1 blocked ABO-induced BMSC differentiation and increased the level of IP-10 but decreased Ets-1. Thus, ABO is a novel inducer for BMSC differentiation to VECs, and Hmbox1 is a key factor in the differentiation. IP-10 and Ets-1 might be relevant targets of Hmbox1 in BMSC differentiation to VECs. These findings provide information on a novel target and a new platform for further investigating the gene control of BMSC differentiation to VECs.

Abstract
Increasing evidence has demonstrated that the senescence of vascular endothelial cells (VECs) has critical roles in the pathogenesis of vascular dysfunction. Finding important factors that regulate VEC senescence will help provide novel therapeutic strategies for vascular disorders. Previously, we found that integrin β4 was involved in VEC senescence. However, the mechanism underlying VEC senescence mediated by integrin β4 remains poorly understand. In this study, we used a mouse in vivo model and showed that the level of integrin β4 in the endothelium of mouse thoracic aorta was increased during natural aging and atherosclerosis. Furthermore, we found that H-ras, caveolin-1, and AP-1 were implicated in the senescent signal pathway mediated by integrin β4 in human umbilical vein ECs (HUVECs). Knockdown of integrin β4 could attenuate HUVEC senescent features, including increased interleukin-8 (IL-8) release and decreased endothelial nitric oxide synthase (eNOS) and NO levels and mitochondrial membrane potential in vitro. Our findings provide new clues illustrating the mechanism of VEC senescence. Integrin β4 might be a potential target for therapy in cardiovascular diseases.

Abstract
An ab initio density functional theory (DFT) study with correction for dispersive interactions was performed to study the adsorption of N(2) and CO(2) inside an (8, 8) single-walled carbon nanotube. We find that the approach of combining DFT and van der Waals correction is very effective for describing the long-range interaction between N(2)/CO(2) and the carbon nanotube (CNT). Surprisingly, exohedral doping of an Fe atom onto the CNT surface will only affect the adsorption energy of the quadrupolar CO(2) molecule inside the CNT (20-30%), and not that of molecular N(2). Our results suggest the feasibility of enhancement of CO(2)/N(2) separation in CNT-based membranes by using exohedral doping of metal atoms.

Abstract
Recent experiments [F. E. Pinkerton, M. S. Meyer, G. P. Meisner, M. P. Balogh, and J. J. Vajo, J. Phys. Chem. C 111, 12881 (2007) and J. J. Vajo and G. L. Olson, Scripta Mater. 56, 829 (2007)] demonstrated that the recycling of hydrogen in the coupled LiBH4/MgH2 system is fully reversible. The rehydrogenation of MgB2 is an important step toward the reversibility. By using ab initio density functional theory calculations, we found that the activation barrier for the dissociation of H2 are 0.49 and 0.58 eV for the B and Mg-terminated MgB2(0001) surface, respectively. This implies that the dissociation kinetics of H2 on a MgB2(0001) surface should be greatly improved compared to that in pure Mg materials. Additionally, the diffusion of dissociated H atom on the Mg-terminated MgB2(0001) surface is almost barrier-less. Our results shed light on the experimentally-observed reversibility and improved kinetics for the coupled LiBH4/MgH2 system.

Abstract
AIM: To evaluate the pain relief effect of psychological intervention and pharmacological analgesia during hepatic arterial chemoem-bolization procedure.
METHODS: Two hundred and sixty-two patients underwent hepatic arterial chemoembolization for unresectable hepatic carcinoma were randomized into pharmacological analgesia group (n = 46) and combined therapy group (n = 216, psychological intervention and medication were performed in turn). The baseline characteristics, psychological status and NRS-10 scores before pain control showed no statistical difference between two groups. All patients were measured with Symptom Checklist-90 (SCL-90) before embolization and pain Numeric Rating Scale-10 (NRS-10) score were recorded before psychological intervention/medication, after psychological intervention (only in combined therapy group) and following medication during therapeutic process.
RESULTS: Postembolization pain was significantly relieved after medication, psychological intervention or combined therapy (t' = 4.47, 5.79, 20.24, P < 0.01). There were obvious differences among the curative effect scores (pre-therapy NRS-10 score-post-therapy NRS-10 score) of the above three therapeutic methods (F = 21.98, P < 0.01). According to the curative effect scores, medication and combined therapy were more satisfactory than psychological intervention (2.71 ± 4.05, 3.40 ± 3.82 vs 1.24 ± 2.76; both P < 0.01). Combined therapy was the best method for pain relief, but its curative effect score indicated no statistical difference from that of medication.
CONCLUSION: Pharmacological analgesia combined with psychological intervention is able to relieve pain efficiently during hepatic arterial chemoembolization procedure.

Abstract
AIM: To assess whether psychological intervention reduces postembolization pain during hepatic arterial chemoembolization therapy.
METHODS: Two hundred and sixty-two patients, who required hepatic arterial chemoembolization for hepatic malignancy and postembolization pain, were randomized into control group (n = 46, receiving medication) and intervention group (n = 216, receiving psychological intervention and medication in turn). The symptom checklist-90 (SCL-90) was used to scale the psychological symptoms of the patients before operation. Pain was scored with a 0 to 10 numeric rating scale (NRS-10) before and after analgesia as well as after psychological intervention (only in intervention group).
RESULTS: All psychological symptomatic scores measured with SCL-90 in the intervention group were higher than the normal range in Chinese (P < 0.05). The somatization, phobia and anxiety symptomatic scores were associated with pain numerical rating score before analgesia (r = 0.141, 0.157 and 0.192, respectively, P < 0.05). Patients in both groups experienced pain relief after medication, psychotherapy or psychotherapy combined with medication during the procedure (P < 0.01). Only some patients in the intervention group reported partial or entire pain relief (29.17% and 2.31%) after psychological intervention. The pain score after analgesia in the intervention group was significantly lower than that in the control group (P < 0.01).
CONCLUSION: Severe psychological distress occurs in patients with hepatic malignancy. Psychological intervention reduces pain scores significantly during hepatic arterial chemoembolization therapy and is thus, highly recommended as a complementary approach to drug analgesia.

Abstract
We synthesized a series of novel small molecules, ethyl 1-(2'-hydroxy-3'-aroxypropyl)-3-aryl-1H-pyrazole-5-carboxylate derivatives 3a-3o, by the reaction of ethyl 3-aryl-1H-pyrazole-5-carboxylate with 2-aryloxymethylepoxide in the presence of potassium carbonate at refluxing in acetonitrile in moderate or excellent yields. We investigated the effects of all the compounds on A549 cell growth. The results showed that 15 compounds could suppress A549 lung cancer cell growth. Among them, compound 3i was the most effective small molecule in inhibiting A549 cell growth. Compound 3f might most effectively induce A549 cell differentiation. Compound 3g remarkably induced cellular vacuolation.

Abstract
How short can single-walled carbon nanotubes (SWNTs) be? How stable are such supershort SWNTs (ss-SWNTs)? This work is the first to address these questions. On the basis of binding energy (E(B)), standard heats of formation , and strain energy (E(S)), we found that SWNTs with only one benzene ring in the axial direction, which we refer to as supershort SWNTs (ss-SWNTs), can be thermodynamically stable. On the basis of the data of E(B), , and E(S), the relative stabilities of ss-SWNTs, fullerenes, polycyclic aromatic hydrocarbons, and butadiyne are discussed. This study has laid a theoretical foundation for the possible synthesis of ss-SWNTs.

Abstract
BACKGROUND AND OBJECTIVE A human glioma spheroid model is used to investigate the efficacy of different light delivery schemes in 5-aminolevulinic acid (ALA)--mediated photodynamic therapy (PDT). The results provide the rationale for the development of an indwelling balloon applicator for optimizing light delivery. STUDY DESIGN/MATERIALS AND METHODS Human glioma spheroids were incubated in ALA (100 or 1000 microg /ml-1) for 4 hours and subjected to various light irradiation schemes. In one set of experiments, spheroid survival was monitored as a function of light fluence rate (5-200 mW cm-2). In all cases, spheroids were exposed to fluences of either 25 or 50 J cm-2. In a second study, the effects of repeated weekly PDT treatments, using sub-threshold fluences, were investigated. One group of spheroids was subjected to three treatments using fluences of 12, 12, and 25 J cm-2. Results were compared to spheroids receiving single treatments of either 12 or 25 J cm-2. A fluence rate of 25 mW cm-2 was used for all three groups of spheroids. In all cases, the effect of a given irradiation scheme was evaluated by monitoring spheroid growth. RESULTS Low fluence rates produce greater cell kill than high fluence rates. The minimum effective fluence rate in human glioma spheroids is approximately 10 mW cm-2. Repeated weekly PDT treatments with sub-threshold fluences result in significant cell kill. In spheroids surviving the PDT treatments, growth is suppressed for the duration of the treatment period. CONCLUSION The results of the in vitro studies support the development of an indwelling balloon applicator for the delivery of light doses in long term multi-fractionated PDT regimens.
