Objective To study the effects of quercetin(QUE) on proliferation of rat glioma C6 cell line in vitro.Methods The cells were divided into 5 treatment groups(10,25,50,75 and 100 ?mol?L~(-1) QUE),blank control and menstruum control group.The rat C6 cells were cultivated to 1?10~6?mL~(-1) in the RPMI 1640 medium,then added into 96 holes board with various doses of QUE by 3 holes per group,and MTT assay was used to observe the proliferation of the cells treated for 24,48 and 72 h.The change of cell cycle was also observed by flow cytometry(FCM) after the cells were treated with 50 and 100 ?mol?L~(-1) QUE for 48 h.The changes of the protein P53 and Bcl-2 of C6 cells treated with 50 ?mol?L~(-1) QUE for 48 h were detected by immunocytochemical methods.(Results With) the augmentation of QUE and the extension of the treated time,the C6 cell growth was inhibited,the A values decreased and the cell number in G_0/G_l phase was increased,the cell numbers in S and G_2/M phases were cut down,and the decreased expression of Bcl-2 protein and the increased expression of P53 protein were also observed after treatment with QUE.Conclusion Inhibitory effect of QUE on C6 cell line is proved to be dependent on the treated time of the drug and the dose of QUE,and the induced apoptosis of C6 cells is implemented by the means of up-regulation of P53 protein expression and down-regulation of Bcl-2 protein expression.

Objective To explore the CT and MR imaging characteristics of intracranial melanomas. Methods CT and MRI characteristics in five patients admitted to our hospital from June 1993 to June 2000 and diagnosed as intracranial melanomas were retrospectively analyzed. Results There were two cases of primary melanoma and three cases of secondary melanoma. All the cases were examined by CT. The lesions presented as high density in 4 cases, and low density in only 1 case. Four cases were examined by MRI. Short T 1 and short T 2 signals were found in 3 cases, and slightly long T 1 and short T 2 signal was found in 1 case. Conclusion There are some special characteristics of melanomas on the MR imaging, which are helpful to ensure the diagnosis and distinguish the primary melanomas from secondary melanomas.

Objective To investigate the relationship between thyroid hormone levels and the attack of arrhythmia after thoracic surgery.Methods Information of 44 patients after thoracic surgery form September 2012 to February 2015 in General Hospital of Tianjin Medical University was collected, and divided in to the arrhythmia group and non-arrhythmia group.A retrospective analysis was carried on their ECG, thyroid hormone levels, and physical health, and the parameters were then compared between the two groups.The correlation of triiodothyronine (T3) level and Acute Physiology and Chronic Health Evaluation (APACHE Ⅱ) was analyzed.Results The arrhymia patients' serum T3 and free triiodothyronine (FT3) levels were below normal levels, while the serum T3 and FT3 levels of the non-arrhythmia patients were within normal range, and the differences between the two groups were significant (P＜0.05).No notable change of other thyroid hormones levels and correlation of T3, FT3 and APACHE Ⅱ score were found.Conclusions There is a significant difference between the arrhythmia and non-arrhythmia groups in serum T3 and FT3 levels.Perioperative thyroid hormone replacement therapy is worthy of consideration and trial in the clinical prevention and treatment of arrhythmia and prognostic improvement of patients.

OBJECTIVE: To diagnoze active ankylosing spondylitis (AAS) by magnetic resonance imaging (MRI). METHODS: MRI of the sacroiliac joint (SIJ) was performed on 48 patients who were clinically diagnosed as probable AS without radiologic evidence of sacroiliitis. Among them 21 were diagnozed as active sacroiliitis with MRI, whose examination was terminated; 27 whose MRI of SIJ did not diagnoze as active sacroiliitis were performed MRI in the thoracic spine. The diagnostic criteria of MRI for AAS of SIJ and/or the thoracic spine were fomulated by consulting documents. The definite diagnosis of AAS was finally made after follow-up for half a year. The sensitivity and specificity of the MRI of SIJ and/or MRI of thoracic spine were assessed. RESULTS: In the 48 patients without radiologic evidence of sacroiliitis, 38 were finally diagnosed as AAS, with established consensus criteria as reference standard. The sensitivity and specificity of the MRI of SIJ were 52.6% and 90.0%, and for the MRI of SIJ and/or the MRI of the thoracic spine 76.3% and 90.0%, respectively. CONCLUSION Clinically probable AS without MRI evidence of sacroiliitis, MRI of the thoracic spine can increase the sensitivity of AAS diagnosis.

Cardiac hypertrophy is a common physiological or pathological process, and pathological cardiac hypertrophy can lead to heart failure, sudden death, etc. The role of microRNA (miRNA or MIR) in myocardial hypertrophy has gradually attracted public attention. miR-1 plays a certain protective role in the occurrence of cardiac hypertrophy. miR-133 is a key factor in the establishment of mast gene program, which is very important for the development of myocardial hypertrophy. Carvedilol and other drugs can regulate the expression of miR-133. miR-208a plays an important physiological role in the cardiovascular system, and its expression level changes dynamically in a variety of cardiovascular diseases such as cardiac hypertrophy, which is closely related to the progression and prognosis of the disease. The expression of miR-199a is up-regulated in pressure-overload cardiac hypertrophy, and it is found that miR-199a can inhibit autophagy of cardiomyocytes and induce the occurrence of cardiac hypertrophy. miR-200c can protect cardiomyocytes through a variety of pathways. miRNA may become an important biomarker or drug therapeutic target for cardiac hypertrophy. With the deepening of the research on non-coding RNAs including miRNA, its regulation on the occurrence of cardiac hypertrophy and the pathological process of heart failure will be further revealed.

Objective To construct the Hut78 cell line with EZH2 gene knocked into by CRISPR/Cas9 system. Methods The EZH2 expression vector pMD-18T-EZH2 with homologous arm and the sgRNA expression vector pSpCas9 (BB)-2A-Puro-sgRNA, which could cut the double stranded genomic DNA, were constructed, and the two vectors were co-transfected into Hut78 cells. Then the expression of EZH2 mRNA was detected by qPCR, and the expressions of EZH2 and H3K27me3 proteins were detected by Western blot assay. Results The pMD-18T-EZH2 and pSpCas9(BB)-2A-Puro-sgRNA recombinant vectors were confirmed by DNA sequencing. When Hut78 cells were transfected with the two recombinant plasmid, qPCR results showed that the expression of EZH2 mRNA was significantly increased, and Western blot analysis showed that the expressions of EZH2 and H3K27me3 proteins were significantly increased. Conclusion EZH2 gene is successfully knocked into Hut78 cells by CRISPR/Cas9 system.

Objective:To investigate the value of machine learning-based computed tomography (CT) images radiomics analysis in preoperative evaluation of surgical portal vein-superior mesenteric vein (PV-SMV) invasion in patients with pancreatic ductal adenocarcinoma (PDAC).Methods:The retrospective study was conducted with 156 consecutive PDAC patients who were underwent surgery at the Affiliated Wuxi No.2 People's Hospital of Nanjing Medical University between January 2010 and July 2021. There were 95 males and 61 females, with the age of (65.7±8.2) years. Patients were randomly split into training set and validation set by a ratio of 3∶2. Minimum redundancy maximum relevance was used to select radiomic features, which were extracted from contrast-enhanced CT images. Five machine learning classifiers were developed, and those models' area under the curve (AUC) values were compared with the conventional radiologic-feature-based evaluation.Results:Ninety-four and 52 patients were included into the training set and validation set, respectively. Their PV-SMV invasion rates were confirmed by intraoperative exploration with 31.9%(30/94) and 40.3%(25/61), respectively. Five models: LASSO regression, random forest, support vector machine, k-nearest neighbor and Naive Bayesian, were established based on ten features from CT images radiomics, and LASSO regression model achieved the highest AUC value compared with the other four models (all P<0.05). Compared with the conventional radiologic evaluation, the LASSO regression model had higher AUC (0.920 vs. 0.752) and sensitivity (92.0% vs. 86.5%)(both P<0.05). Conclusion:Machine learning-based CT images radiomics analysis can be used to evaluate PV-SMV invasion status preoperatively in PDAC. The LASSO regression model showed better performance than the conventional radiologic evaluation.
