BACKGROUND:MicroRNAs (miRNAs) play an important role in a variety of diseases. Investigation of miRNA expression profile in degenerative lumbar scoliosis is beneficial for understanding its pathogenesis, providing a novel therapeutic target. Therefore, we tested the hypothesis that miRNAs promote intervertebral disc degeneration through the interleukin-10/STAT3 signaling pathway, a potential regulator of intervertebral disc degeneration.
OBJECTIVE:To compare the differentialy expressed miRNAs in the intervertebral disc tissues from patients with degenerative lumbar scoliosis and normal controls and to identify specific miRNAs in degenerative lumbar scoliosis folowed by functional validation.
METHODS: An initial screening of miRNA expression in nucleus pulposus tissues by miRNA Solexa Sequencing was performed in samples from 10 patients with degenerative lumbar scoliosis and 10 controls, respectively. Subsequently, differentialy expressed miRNAs were validated using qRT-PCR. The level of differentialy expressed miRNAs in degenerative nucleus pulposus tissues was investigated. Then, functional analysis of the miRNAs in regulating type II colagen expression was carried out. Western blot and luciferase reporter assay were used to further confirm the target gene.
RESULTS AND CONCLUSION: We identified 30 miRNAs that were differentialy expressed (16 upregulated and 14 downregulated) in patients with degenerative lumbar scoliosis compared with controls. Folowing qRT-PCR confirmation, Has-let-7f was significantly down-regulated in degenerative nucleus pulposus tissues as compared with controls. Moreover, its level was correlated with the severity of disc degeneration. Overexpression of Has-let-7f promoted type II colagen expression in nucleus pulposus cels. Knockout of interleukin-10 induced effects on nucleus pulposus cels similar to Has-let-7f. Bioinformatics target prediction identified interleukin-10 as a putative target of Has-let-7f. Furthermore, luciferase reporter assays demonstrated that Has-let-7f altered the expression of STAT3 and matrix metaloproteinase-2. These findings indicate that the downregulation of Has-let-7f induces type II colagen loss by directly targeting inleukin-10, thereby resulting in intervertebral disc degeneration and degenerative lumbar scoliosis. Has-let-7f is likely to be a novel therapeutic target for degenerative lumbar scoliosis.

BACKGROUND:MicroRNAs are widely involved in the regulation of protein expression, and play a critical role in many physiological and pathological processes in the body. But microRNA expression profile in degenerative lumbar scoliosis is rarely reported and understood. OBJECTIVE:To compare the microRNA expression profile in the normal intervertebral disc and degenerative lumbar scoliosis and to identify degenerative lumbar scoliosis-specific microRNAs, folowed by functional validation. METHODS: Total RNA samples were extracted from the nucleus pulposus tissues of 57 patients with degenerative lumbar scoliosis as experimental groups and the normal nucleus pulposus tissues of 42 patients with lumbar fractures as control group. An initial screening of differentialy expressed microRNAs in the nucleus pulposus tissues by microRNA microarray was performed in 10 samples from each group. Subsequently, differentialy expressed microRNAs were validated using real-time quantitative RCR. The level of differentialy expressed microRNAs in the degenerative nucleus pulposus tissues was investigated. Then, the functional analysis of microRNAs in regulating colagen II expression was carried out. Western blot and luciferase reporter assay were also used to detect target genes. RESULTS AND CONCLUSION:We identified 22 microRNAs that were differentialy expressed (17 upregulated and 5 downregulated) in degenerative lumbar scoliosis patients compared with the controls. Folowing real-time quantitative RCR confirmation, miR-491-5p was significantly down-regulated in degenerative nucleus pulposus tissues in comparison with the controls. Moreover, its level was closely correlated with the pathological grading of disc degeneration. Overexpression of miR-491-5p promoted type II colagen expression in nucleus pulposus cels. Bioinformatics target prediction identified matrix metaloproteinase-9 as a putative target of miR-491-5p. Furthermore, luciferase reporter assays demonstrated that miR-491-5p directly targeted matrix metaloproteinase-9 and affected its protein expression in nucleus pulposus cels. These results show that the downregulation of miR-491-5p induces type II colagen loss by directly targeting matrix metaloproteinase-9, thereby resulting in degeneration of the intervertebral disc and degenerative lumbar scoliosis. This study also underscores the potential of miR-491-5p as a novel therapeutic target in degenerative lumbar scoliosis.

Aim To screen the potential inhibitors of post-transcriptional activity of pro-inflammatory media-tor TNF-α from the lipophilic constituents in Chinese Medicine Salvia miltiorrhiza Bunge ( Danshen) , we es-tablished dual luciferase reporter gene system pGL3-TNF-α3′UTR ( 3′untranslated region ) co-transfected with Renilla control gene. Methods Complementary DNA ( cDNA) template was obtained from human um-bilical vein endothelial cells ( HUVECs ) . The full length DNA of TNF-α 3′-UTR was amplified through PCR, and then connected the luciferase reporter vector pGL3-control after enzyme digestion. pGL3-TNF-α 3′UTR constructs were co-transfected with pSVRenilla into the mononuclear macrophages RAW264. 7 cells. The relative activity of reporter genes was measured by dual luciferase reporter ( DLR ) assay system after the stimulus of lipopolysaccharide ( LPS ) in presence or absence of tanshinones compounds. Results The pGL3-TNF-α3′UTR luciferase reporter gene was suc-cessfully constructed. The cloning DNA fragment and sequence were both consistent with the GENBANK da-tabase. LPS significantly induced the relative reporter activityof RAW264 . 7 cells transfected with pGL3-TNF-α 3′UTR. Among four tanshinones compounds, we found only cryptotanshinone could significantly de-crease LPS-induced relative reporter activity. Conclu-sion The pGL3-TNF-α 3′UTR construct combined with DLR assay system was successfully established, which can be used to discover the agents such as cryp-totanshinone that regulate the post-transcription of TNF-α in treatment of inflammatory and malignant dis-eases.

Tumor metastasis is one of the most important biologi-cal characteristics of malignant tumor, and it is also the main factors that cause treatment failure and poor prognosis. Clinical studies have shown that the number of platelets in patients with malignant tumor increased more significantly than that in benign tumor patients and healthy people, which indicate that platelet might be involved in the development process of tumor. Further study found that in the process of cancer spreading to blood, platelet could interact with tumor cells to form tumor emboli, helped tumor cells escape from immune surveillance, thus pro-moted the tumor metastasis. In recent years, related mechanisms on platelets in promoting tumor metastasis were revealed gradual-ly, and several targeted therapies based on platelets were also carried out. This paper reviews the role of platelet in mediating tumor metastasis by hematogenous spread and its mechanisms and discusses the therapy strategies that target platelet, which may provide references for follow-up research and clinical treat-ment.

Objective To explore the effect of childhood trauma on escitalopram treatment of adult depression. Methods There were 68 adult patients with major depression disorder recruited. All patients were assessed with Childhood Trauma Questionnaire ( CTQ ) and given 8 weeks of standardized treatment with escitalopram. Beck Depression Inventory ( BDI) and HAMD-17 were assessed at the end of the 2nd,4th and 8th week respectively. The changes of BDI score and HAMD-17 score in patients with different CTQ fac-tors were observed. Results ( 1) The overall effect of intervention was 25. 0％ at the end of 4th week and 45. 6％ at the end of 8th week. The total effective rate was 94. 1％. At the end of 4th week,there was no sig-nificant difference in the clinical recovery rate between the positive group(19. 5％) and the negative group (33. 3％)(χ2=1. 66,P>0. 05). There was no significant difference in clinical recovery between the two groups at the end of 8th week(positive group :39. 0％,negative group :55. 6％,χ2=1. 79,P>0. 05). (2) The total score reduction rate of HAMD-17((46. 26±24. 79)％,(58. 39±23. 25)％) and BDI((51. 63± 16. 03)％,(66. 28±18. 05)％) at the end of 4th week and the total score reduction rate of BDI at the end of 8th week ((59. 13±15. 42)％,(68. 50±20. 91)％)in the positive group were lower than those in the nega-tive group (P<0. 05) . ( 3) Except for sexual abuse,there was a significant negative correlation between CTQ scores and the reduction rate of BDI scores at end of 4th and 8th week( r=-0. 46--0. 06,P<0. 05) . Conclu-sion Childhood trauma has adverse effects on the efficacy of escitalopram in the treatment of adult depres-sion.

Objective:To explore the effect of match between childhood stress and adulthood stress on mental health status.Methods:Adult healthy volunteers( n=239) and adult mental disorder patients were examined by questionnaires or telephone interviews.Childhood trauma questionnaire (CTQ) and lifetime stress event list were used for measure of CS and AS, DSM5-level-1-cross-cutting-symptom-measure (DSM5-L1CCSM) and self-rating depression scale (SDS) for mental health outcomes.Subjects were grouped according to positive (+ ) / negative (-) stress events into five groups: CS+ AS+ Matched ( n=108), CS+ AS+ mismatched( n=240), CS-AS+ ( n=100), CS+ AS-( n=79), and CS-AS-( n=99). The data of stress and mental health status were compared and analyzed among stress groups. Results:The distributions of positive stress events among 626 volunteers were 68.2% with CS+ , 71.6% with AS+ , 17.3% with C+ A+ M+ .There were differences among groups in all parameters (all P<0.05) except for gender.Age, years of education, CS and emotional abuse were influencing factors of onset of AS( P<0.01). MANCOVA analysis showed that factors about the interaction of AS and CS had attribution on DSM5-L1CCSM and SDS ( P<0.01). Conclusion:CS has a facilitatory effect on AS.The match of CS-AS is an important risk factor of adulthood mental health outcomes.Re-experiencing the same type of CS in adulthood would worsen adulthood mental health status.

OBJECTIVE: The aims of the present study were to explore the occurrence of childhood trauma and importantly to determine the impacts of childhood trauma on psychosocial features in a Chinese sample of young adults. METHODS: A survey was carried out in a group of 555 university students by using Childhood Trauma Questionnaire (CTQ), Self-rating Depression Scale (SDS), Self-rating Anxiety Scale (SAS), Dysfunctional Attitudes Questionnaire (DAS), Eysenck Personality Questionnaire (EPQ), and Social Support Rating Scale (SSRS). The moderate-severe cut-off scores for CTQ were used to calculate the prevalence of childhood trauma, and then psychosocial features were compared between individuals with and without childhood trauma. RESULTS: A proportion of 18.6% of university students had self-reported childhood trauma exposures. Subjects with childhood trauma reported higher scores of SDS, SAS, DAS, and psychoticism and neuroticism dimensions of EPQ (t=4.311–5.551, p < 0.001); while lower scores of SSRS and extraversion dimension of EPQ (t=-4.061– -3.039, p < 0.01). Regression analyses further revealed that scores of SAS and DAS were positively (Adjusted B=0.211–0.230, p < 0.05), while scores of SSRS were negatively (Adjusted B=-0.273– -0.240, p < 0.05) associated with specific CTQ scores. CONCLUSION: Childhood trauma is still a common social and psychological problem. Individuals with childhood trauma show much more depression, anxiety, distorted cognition, personality deficits, and lower levels of social support, which may represent the social and psychological vulnerability for developing psychiatric disorders after childhood trauma experiences.
