Objective: To explore the effect of kynurenine pathway on the osteogenic differentiation of periodontal ligament stem cells (PDLSC). Methods: Unstimulated saliva samples were collected from 19 patients with periodontitis (periodontitis group) and 19 periodontally healthy individuals (health group) in Nanjing Stomatological Hospital, Affiliated Hospital of Medical School, Nanjing University from June to October of 2022. Contents of kynurenine and the metabolites in saliva samples were analyzed by ultra-performance liquid chromatography-tandem mass spectrometry. The expressions of indoleamine 2, 3-dioxygenase (IDO) and aryl hydrocarbon receptor (AhR) were further detected by immunohistochemistry in gingival tissues. The PDLSC used in this study were isolated from extracted teeth for orthodontic treatment in Nanjing Stomatological Hospital, Affiliated Hospital of Medical School, Nanjing University from July to November of 2022. Experiments were then conducted using the cells by incubating with (kynurenine group) or without kynurenine (control group) in vitro. Seven days later, alkaline phosphatase (ALP) staining and assays of ALP activity were performed. Real-time fluorescence quantitative PCR (RT-qPCR) was utilized to detect the expressions of osteogenic related genes ALP, osteocalcin (OCN), runt-related transcription factor 2 (RUNX2), collagen type-Ⅰ (COL-Ⅰ) as well as the kynurenine pathway-associated genes AhR, cytochrome P450 family (CYP) 1A1, CYP1B1. Western blotting was used to detect the expression levels of RUNX2, osteopontin (OPN) and AhR proteins on day 10 and alizarin red staining was performed to observe the formation of mineral nodules on day 21 in control group and kynurenine group. Results: Salivary concentrations of kynurenine [8.26 (0, 19.60) nmol/L] and kynurenic acid [11.4 (3.34, 13.52) nmol/L] were significantly higher in the periodontitis group than in the health group [0.75(0, 4.25) nmol/L, 1.92(1.34, 3.88) nmol/L] (Z=-2.84, P=0.004; Z=-3.61, P<0.001). The expression levels of IDO (18.33±2.22) and AhR (44.14±13.63) in gingival tissues of periodontitis patients were significantly higher than that of the health group (12.21±2.87, 15.39±5.14) (t=3.38, P=0.015; t=3.42, P=0.027). In vitro, the ALP activity of PDLSC in the kynurenine group (291.90±2.35) decreased significantly compared with the control group (329.30±19.29) (t=3.34, P=0.029). The mRNA expression levels of ALP, OCN and RUNX2 in the kynurenine group (0.43±0.12, 0.78±0.09, 0.66±0.10) were decreased compared with the control group (1.02±0.22, 1.00±0.11, 1.00±0.01) (t=4.71, P=0.003; t=3.23, P=0.018; t=6.73, P<0.001), while the levels of AhR and CYP1A1 were increased in the kynurenine group (1.43±0.07, 1.65±0.10) compared with those in the control group (1.01±0.12, 1.01±0.14) (t=5.23, P=0.006; t=6.59, P<0.001). No significant difference was observed in COL-Ⅰ and CYP1B1 mRNA levels between groups. The protein levels of OPN, RUNX2 (0.82±0.05, 0.87±0.03) were reduced and that of AhR (1.24±0.14) was increased in the kynurenine group compared with those in the control group (1.00±0.00, 1.00±0.00, 1.00±0.00) (t=6.79, P=0.003; t=7.95, P=0.001; t=3.04, P=0.039). Conclusions: Over-activated kynurenine pathway in periodontitis patients can promote upregulation of AhR and suppress the osteogenic differentiation of PDLSC.

"Kidney essence" is a profound concept in the theory of traditional Chinese medicine. But its biological basis is unknown until now, resulting in the therapeutic effects of traditional Chinese drugs on reinforcing kidney for supplementing essence hard to be evaluated. This study aimed, to explore the potential biological basis and mechanism of traditional Chinese drugs of reinforcing kidney for supplementing essence on diseases related to deficiency of kidney essence through network pharmacology analysis on the intersection of targets of drugs and diseases. The targets for ingredients in Rehmanniae radix praeparata (RRP), Polygoni multiflori radix praeparata (PMRP) and Polygonati rhizome (PR) were gathered from TCMSP and TCMID database. Osteoporosis, Alzheimer's disease, anemia, infertility and oligospermia targets were collected from OMIM and DisGeNET database. Drug-compound-target-disease (DCTD) network was established with Cytoscape 3.6.1 software, then Clue GO and DAVID database was used to acquire the annotation about GO terms and signaling pathways. Natural aging mice, an acknowledged syndrome model of deficiency of kidney essence, and RRP were used to verify the predictive targets by Western blot analysis. All animal experiments were conducted in accordance with the international guidelines and regulations for the care and use of animals. DCTD network showed that the intersection of drugs and diseases included 175 common targets. After topology analysis, 71 key were screened out targets which were associated with GO annotation exhibited that biological processes (including transcription regulation, RNA metabolism regulation, and DNA-dependent transcription regulation), cell composition (including nuclear lumen, organelle lumen, and membrane closure lumen), molecular function (including transcription regulation, transcription factor activity, and enzyme binding), and signaling pathway (including peroxisome proliferator-activated receptor alpha (PPARα), mitogen-activated protein kinase (MAPK), hypoxia-inducible factor 1 (HIF-1), erythropoietin (EPO) and other signaling pathways. In natural aging mice, the expressions of HIF-1α, growth factor receptor-bound protein 2 (GRB2), MAPK3, signal transducer and activator of transcription 5A (STAT5A), transcription factor AP-1 (JUN) and proto-oncogene c-Fos (FOS) in EPO pathway were significantly decreased. RRP significantly reversed the decrease of the above targets. Above all, these results indicated that the therapeutic effects of traditional Chinese drugs of reinforcing kidney for supplementing essence on deficiency of kidney essence may be related to the regulation of nuclear transcriptional activity and EPO signaling pathway.

Objective:To analyze the differential expression profile of circRNA and the expression changes of Hippo signaling molecule YAP in renal ischemia-reperfusion injury of mice.Methods:A model of renal IR damage in mice was induced, and serum creatinine (Scr) and urea nitrogen (BUN) concentrations and histological changes of samples were detected to assess renal function and tubular injury. Illumina HiSeq 2500 system was used for high-throughput paired-end sequencing to establish the circRNA expression profile with significant differential expression. Real-time quantitative polymerase chain reaction (qRT-PCR) verified the sequencing results and detected related genes. Gene function (GO) and pathway (KEGG) analysis were performed to predict the biological processes and the major signal pathways involved by differentially expressed circRNAs. The expression level of the main signaling molecule was examined by western blot.Results:Twenty-one distinctly differentially expressed circRNAs ( fold change ≥ 2) were found in IR 24 h kidney tissues compared with the expression in the control groups ( P < 0.05), among which 10 circRNAs were observed to be up-regulated and 11 down-regulated. CircRNA.1100 and circRNA.1122 were randomly (random number) selected for verification by qRT-PCR, and the relative expressions after renal IR 1day were decreased by (0.23±0.016) and (0.36±0.12), respectively, which were highly consistent with the sequencing trends. Analysis of biological functions and pathways showed that differential expression circRNA was significantly enriched in cell cycles, division, growth, apoptosis, death, and Hippo signaling pathways. The Hippo pathway effector molecule YAP protein was significantly up-regulated after renal IR 1day and until the 3rd day of IR. Conclusions:CircRNA may be involved in the regulation of renal IR injury. CircRNA and Hippo pathway may play a key role in the development of renal IR injury.

OBJECTIVE: Anger attacks have been observed in patients with obsessive-compulsive disorder (OCD), often triggered by obsessional triggers. However, few studies have reported the clinical characteristics and correlates of anger attacks among Chinese patients with OCD. METHODS: A total of 90 adults with a primary diagnosis of OCD, ranging from 15 to 78 years old, participated in the study. Participants were administered the Rage Outbursts and Anger Rating Scale (ROARS), Yale-Brown Obsessive-Compulsive Scale-Second Edition, and Brown Assessment of Beliefs Scale by a trained clinician. Patients completed the Obsessive-Compulsive Inventory-Revised and Depression Anxiety Stress Scale-21. RESULTS: A total of 31.3% of participants reported anger outbursts in the past week, and ROARS scores had no significant correlation with age, duration of illness, OCD severity, depression, or stress. However, ROARS scores were negatively related to education level, and positively related to obsessing symptoms and anxiety. CONCLUSIONS These data suggest that anger attacks are relatively common in Chinese patients with OCD. The severity of anger attacks is related to educational level, obsessing symptoms, and anxiety, which may be a latent variable reflecting executive functioning and emotion regulation skills.

OBJECTIVETo investigate the expression of LRG-1 in clinical specimens and Tca8113 cell line of tongue carcinoma and analyze the relationship between LRG-1 expression and the clinicopathological parameters.

METHODSLRG-1 expression was detected in 40 tongue squamous cell carcinoma (TSCC) tissues and paired normal adjacent tissues, 20 atypical hyperplasia tissues of the tongue, and 20 tissues of tongue cancer in situ using immunohistochemical method. The expression of LRG-1 in Tca8113 cell line was detected using flow cytometry. The expression of LRG-1 was also detected in human TSCC tissues and Tca8113 cells with Western blotting. The effect of LRG-1 on the proliferation of HUVECs was determined using MTT assay, and its effect on angiogenesis was evaluated with Matrigel tube formation assays.

RESULTSHuman TSCC tissues had a significantly higher rate of positive expression for LRG-1 (85%, 34/40) than the adjacent tissues (10%, 4/40), invasive tongue cancer (30%, 6/20), and tongue cancer in situ (50%, 10/20) (P<0.05). LRG-1 expression was correlated with the degree of tumor differentiation, clinical stage and lymph node metastasis of the tumor (P<0.05) but not with the patients' age or gender. In the in vitro experiment, LRG-1 promoted HUVEC proliferation and angiogenesis.

CONCLUSIONAbnormal LRG-1 expression is present in the human TSCC tissue and Tca8113 cells. LRG-1 can promote HUVEC proliferation and angiogenesis in vitro, suggesting its possible role in promoting tumor angiogenesis.

This study was aimed to explore the molecular mechanism of the regulatory effects of ICAM-1 on the differentiation of mesenchymal stem cells (MSC) to adipocytes. The murine MSC cell line C3H10T 1/2 was treated with the supernatants contained plasmid MIGR1-ICAM-1 and MIGR1-ICAM-1/MSC (high expression of ICAM-1), the activation of the pathway was detected by Western blot. The ICAM-1 modified MSC and its control cells named MIGR1/MSC were cultured in adipocyte medium with or without the inhibitors of the ERK, P38, and JNK pathway. Oil-red-O staining was used to detect the lipid accumulation, and the expression of C/EBPα and PPARγ in differentiation of MSC to adipocyte were examined by real-time-PCR. The results showed that the overexpression of ICAM-1 stably activated the ERK, P38, and JNK pathway in MSC. Inhibiting of the activation of ERK pathways by chemical inhibitors up-regulated the mRNA expression level of C/EBPα and PPARγ in MIGR1-ICAM-1/MSC while inhibiting of P38 pathway resulted in lower mRNA expression of the transcription factors. Consistent with the mRNA expression, the lipid droplets were getting smaller and number of adipocytes increased when P38 pathway was inhibited, while bigger lipid droplet and increased quantity of adipocytes were identified in MIGR1-ICAM-1/MSC with the addition of ERK pathway inhibitor. It is concluded that ICAM-1 may suppress MSC differentiate into adipocyte via activating ERK pathway, while it can maintain the adipogenesis of MSC though P38 pathway.

This study was aimed to construct the mouse VCAM-1 expression vector, to establish the stably transfected MSC line and to investigate the effect of VCAM-1-modified mesenchymal stem cells (MSC) on the immunological characteristics of MSC. The cDNA of murine VCAM-1 gene was amplified by RT-PCR from the total RNA isolated from the mouse spleen; then the cDNA was inserted into the retrovirus vector PMSCVmigr-1; the recombinant plasmid was confirmed by restriction endonuclease experiments and sequencing, then designated as PMSCVmigr-1-mVCAM-1; the recombinant plasmid PMSCVmigr-1-mVCAM-1 was transfected into 293 cells by lipofecamin and the supernatant was collected to transfect MSC cell line (C3H10T1/2). Moreover, VCAM-1 expression on MSC was evaluated by FACS. Furthermore, the inhibitory effect of VCAM-1-MSC on lymphocytic transformation was tested by (3)H-TdR incorporation assay. The results indicated that the successful construction of recombinant retroviral expression plasmid of mouse VCAM-1 was confirmed by digesting and sequancing. After transfection of MSC with retroviral supernaptant, the high expression of VCAM-1 on MSC could be detected by flow cytometry. The MSC high expressing VCAM-1 could significantly inhibit the proliferation of Con A-inducing lymphocytes in dose-depentent marrer. It is concluded that recombinant retroviral encoding VCAM-1 (PMSCVmigr-1-mVCAM-1) has been successfully constructed and mouse VCAM-1 has been stably expressed in C3H10T1/2. MSC over-expressing VCAM-1 show more potent immunosuppressive effect on cellular immune reaction in vitro. Our data laid a foundation for the subsequent studying the effect of VCAM-1 transfecting into MSC on immune related disease study.

OBJECTIVETo identify and investigate clinicopathological features of B cell lymphomas with concurrent myc and bcl-2/IgH or bcl-6 translocations ("double-hit" lymphoma).

METHODSTissue microarray was constructed from formalin-fixed and paraffin-embedded tissue samples of aggressive B cell lymphomas diagnosed between 2009 and 2012, including 129 cases of diffuse large B cell lymphoma (DLBCL), 5 cases of B-cell lymphoma, unclassifiable with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma (BCLU), 7 cases of Burkitt lymphoma and 4 cases of high-grade follicular lymphoma with diffuse large B cell lymphoma component. Interphase fluorescence in-situ hybridization (FISH) was performed with a panel of probes including myc, bcl-2/IgH and bcl-6 to document related gene translocation and copy number changes. Medical record review was performed and follow-up data was recorded.

RESULTSAmong 145 cases, 5 cases (3.4%) of B cell lymphomas with concurrent myc and bcl-2/IgH or bcl-6 rearrangements (double-hit lymphomas) were identified, including 2 cases involving myc and bcl-2 translocations (1 DLBCL and 1 BCLU), and 3 cases involving myc and bcl-6 translocations (all DLBCLs). Three cases with concurrent bcl-2/IgH and bcl-6 translocations were found. Single gene translocations or increase of copy numbers were found in 66 cases, representing 51.2% (66/129) of all de novo DLBCLs. Ki-67 index of the 5 "double-hit" lymphomas ranged from 60% to 100%. Clinical follow-up data were available in 4 of the 5 "double-hit" lymphoma patients, three of whom died within 2 years and 1 patient was alive after 36 months of follow-up.

CONCLUSIONS"Double-hit" B-cell lymphomas are rare and can only be identified by molecular detection. They should not be considered synonymous with BCLU morphologically, and may present entities within other morphological spectra. Most of the patients have a poor prognosis. Further in-depth studies of larger case numbers are required to determine the pathologic and genetic variables of the lesion.
