Salidroside Regulates the miRNA-1343-3p/MAP3K6/MMP24 Signaling Molecules to Inhibit Proliferation and Invasion of Gastric Cancer Cells / 中山大学学报(医学科学版)

ObjectiveThe aim of this study is to investigate the role of salidroside in regulating the miR-1343-3p/MAP3K6 （mitogen-activated protein kinase kinase kinase 6）/MMP24 （membrane-type matrix metalloproteinase 24） signaling pathway to inhibit gastric cancer cell proliferation and migration. MethodsHuman gastric cancer cells （MGC-803） were divided into several groups based on different salidroside concentrations： a control group （0 μmol/mL）， a low-dose group （6 μmol/mL）， a medium-dose group （12 μmol/mL）， and a high-dose group （24 μmol/mL）. The anti proliferative effects of salidroside on human gastric cancer cells were evaluated by CCK-8 assay. Clonogenic assay was used to examine the effects of salidroside drugs on the clonogenic ability of human gastric cancer cells. Transwell assay was performed to detect the effect of salidroside on the invasive ability of human gastric cancer cells. Cell scratch assay was performed to detect the effect of salidroside on the migration ability of human gastric cancer cells. The miRNA expression profile was analyzed by using RNA-seq in cancer cells for 24 h after salidroside treatment. The differentially expressed miRNAs were clustered and their target genes were predicted. Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） were used to analyze and predict the functions of these target genes， and the interaction networks were established. Immunocytofluorescence was used to detect the expression of target proteins， and the transcription of candidate genes was detected by q-PCR. ResultsCCK-8 cytotoxicity experiments showed that salidroside inhibited the proliferation of MGC-803 cells （P < 0.01）. Cell cloning experiments showed that salidroside reduced the clonal formation capacity of MGC-803 cells （P < 0.000 1）. Cell invasion experiments showed that salidroside reduced the MGC-803 cell invasion capacity （P < 0.000 1）. Cell scratch experiments showed that salidroside reduced the cell migration capacity （P < 0.000 1）. RNA-seq findings showed that the expression of 44 miRNAs changed significantly after salidroside treatment in cancer cells （P < 0.05）. Bioinformatic analysis showed that there were 1 384 target mRNAs corresponding to the differentially expressed miRNAs， and the expression of the tumor suppressor miR-1343-3p was significantly upregulated after salidroside treatment （P < 0.01），and resulted in down-regulated transcription of MAP3K6 and MMP24 genes which are related to the proliferation and migration of cancer cells （P < 0.05）. Immunofluorescence experiments demonstrated that salidroside reduced protein expression levels in MAP3K6 and MMP24 genes （P < 0.000 1）. q-PCR experiments showed that salidroside reduced the mRNA expression level of MAP3K6 and MMP24 genes （P < 0.000 1）， while miRNA expression in miR-1343-3p gene was upregulated （P < 0.000 1）. ConclusionSalidroside regulates the miRNA-1343-3p/MAP3K6/MMP24 signaling molecules to inhibit proliferation and invasion of gastric cancer cells.

Validity of Chinese Version of the Composite International Diagnostic Interview-3.0 in Psychiatric Settings / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The Composite International Diagnostic Interview-3.0 (CIDI-3.0) is a fully structured lay-administered diagnostic interview for the assessment of mental disorders according to ICD-10 and Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria. The aim of the study was to investigate the concurrent validity of the Chinese CIDI in diagnosing mental disorders in psychiatric settings.</p><p><b>METHODS</b>We recruited 208 participants, of whom 148 were patients from two psychiatric hospitals and 60 healthy people from communities. These participants were administered with CIDI by six trained lay interviewers and the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I, gold standard) by two psychiatrists. Agreement between CIDI and SCID-I was assessed with sensitivity, specificity, positive predictive value and negative predictive value. Individual-level CIDI-SCID diagnostic concordance was evaluated using the area under the receiver operator characteristic curve and Cohen's K.</p><p><b>RESULTS</b>Substantial to excellent CIDI to SCID concordance was found for any substance use disorder (area under the receiver operator characteristic curve [AUC] = 0.926), any anxiety disorder (AUC = 0.807) and any mood disorder (AUC = 0.806). The concordance between the CIDI and the SCID for psychotic and eating disorders is moderate. However, for individual mental disorders, the CIDI-SCID concordance for bipolar disorders (AUC = 0.55) and anorexia nervosa (AUC = 0.50) was insufficient.</p><p><b>CONCLUSIONS</b>Overall, the Chinese version of CIDI-3.0 has acceptable validity in diagnosing the substance use disorder, anxiety disorder and mood disorder among Chinese adult population. However, we should be cautious when using it for bipolar disorders and anorexia nervosa.</p>

Effect of Naoshuantong capsule on change of SSQOL index in patients with ischemic stroke in six mouths follow-up / 中国中药杂志

To evaluate the effect of Naoshuantong capsule on the life quality of patients with ischemic stroke in six months of follow-up studies, and observe the adverse events. The results would provide reference for the secondary prevention on the recovery stage of ischemic stroke. 696 patients from 12 Class III Grade I hospitals nationwide were divided into 2 groups by central randomization system. The study group, 344 cases, were treated with Naoshuantong capsule plus Aspirin, and the control group, 352 cases, were treated with Aspirin. The patients were treated for 6 months. At the end of treatment, SS-QOL used for evaluating the quality of life was observed. The safety index was defined by adverse observation event. The incidence of adverse events and laboratory tests results were observed before and after treatment at the same time. The results indicated that compared to the control group, the treatment group had significant statistical difference in the impact of effort, self-care ability and the the work or labor ability of patients (P < 0.05). No serious adverse events were observed. Naoshuantong capsule showed some superiority to Asprin on improving the quality of life on patients with ischemic stroke, and it could be used in secondary prevention on the recovery stage of ischemic stroke. Naoshuantong capsule is safe and effective in the treatment of convalescence ischemic stroke.

Difference between the cognitive and control ability and the responsibility in forensic psychiatry evaluation / 法医学杂志

OBJECTIVE@#To analyze the difference between the cognitive and control ability and the responsibility in forensic psychiatry evaluation.@*METHODS@#To compare the results of the responsibility evaluation from 2001.1 to 2006.10 (the first period) with that of the cognitive and control ability evaluation from 2006.11 to 2010.10 (the second period). The admissibility opinions on court judgment and evaluation were investigated by return visit. The legal professions' opinions on forensic psychiatric issues from the police office, the procuratorate, the court, and the judiciary were investigated.@*RESULTS@#There was no significant difference of the criminal types between two periods (P > 0.05). There was significant difference of the diagnostic types between two periods (P < 0.05). The proportion of normal range and part loss of the cognitive and control ability in the second period were higher than that in the first period, but the proportion of complete loss of the cognitive and control ability in the second period was lower than that in the first period (P < 0.05). Among the legal professions, 70.5% of them thought that "the evaluation of cognitive and control ability" was different from "the evaluation of criminal responsibility" and 94.9% of them thought that "to confirm the influence of the forensic psychiatric evaluation of mental disorder on the crime behavior" or "to assess of cognitive and control ability" met requirements of normative judicial expertise.@*CONCLUSION@#The evaluation of cognitive and control ability is more aligned with legal requirements and behavioral norms of own subject than the evaluation of responsibility.
