ABSTRACT
In the electroencephalography (EEG) monitoring of patients with hypoxic-ischemic encephalopathy, generalized periodic discharges are often monitored abnormal waveforms. When there are some features of generalized periodic discharges (e.g., frequency≥1.5 Hz or plus), it indicates that the patient is at high risk for seizures or has a poor prognosis. Compared with conventional EEG, the time of continuous EEG monitoring is longer, so the detection rate of these waveforms is higher. At present, scholars at home and abroad have studied these waveforms, but there is controversy about the significance of these waveforms. In this paper, the definition and characteristics of these waveforms and their significance in determining prognosis and guiding treatment in patients with hypoxic-ischemic encephalopathy are reviewed.
ABSTRACT
Objective:To investigate the value of 18F-FDG total-body PET/CT dynamic imaging in evaluating the efficacy of early radiotherapy for MDA-MB-231 breast cancer bearing nude mice. Methods:MDA-MB-231 breast cancer bearing nude mice were established and divided into control group and radiotherapy group based on the random number table method ( n=10 for each group). 18F-FDG total-body PET/CT dynamic imaging was performed before and after the radiotherapy. The SUV max and the maximum tracer uptake net influx constant ( Kimax) of tumors, and the target-to-background ratio (TBR) were calculated. The change of tumor volume was recorded. The value of 18F-FDG total-body PET/CT dynamic imaging in evaluating the efficacy of radiotherapy was accessed using pathological findings as the reference. Paired t test, independent-sample t test and Pearson correlation analysis were used for data analysis. Results:After radiotherapy, SUV max and Kimax(4.66±0.46 and 0.14±0.03) were reduced in the radiotherapy group compared with those before radiotherapy (5.30±0.52 and 0.19±0.03; t values: 4.61, 8.31, P values: 0.001, <0.001), while the SUV max (5.94±0.74 vs 5.24±0.50) and Kimax (0.23±0.03 vs 0.19±0.02) were increased compared with baseline in the control group ( t values: 4.77, 6.87, P values: 0.001, <0.001). TBR Ki was significantly higher than TBR suv based on all images of the 2 groups (14.11±5.58 vs 5.91±1.60; t=8.92, P<0.001). The tumor volume in the radiotherapy group decreased compared with that before radiotherapy, but the difference was not statistically significant ((0.74±0.12) vs (0.81±0.08) cm 3; t=2.24, P=0.052). The results of immunohistochemistry showed that glucose transport protein (Glut)1 was highly expressed in tumors, and the Glut1 positive cell percentage of the radiotherapy group was significantly lower than that of the control group ((38.30±6.18)% vs (69.78±5.37)%; t=12.17, P<0.001). The expression of Glut1 was significantly positively correlated with SUV max and Kimax(the control group: rsuv=0.75, P=0.012; rKi=0.77, P=0.010; the radiotherapy group: rsuv=0.67, P=0.035; rKi=0.77, P=0.010). The apoptosis index (AI) of tumor cells in the radiotherapy group was higher than that in the control group ((24.15±4.00)% vs (10.15±3.05)%; t=8.85, P<0.001). Conclusion:18F-FDG total-body PET/CT dynamic imaging can sensitively monitor the effect of early radiotherapy in MDA-MB-231 breast cancer bearing nude mice.

ABSTRACT
Objective:The methods of network pharmacology were adopted to predict Multi-component Chinese Medicine （MCCM） with anti-tumor activity from Shuanghuanglian （SHL）. Furthermore， the pharmaceutical activity of CT26 colon cancer was verified in vitro and in vivo. Method:Based on the Traditional Chinese Medicine Systems Pharmacology Database （TCMSP）， the Handbook of Active Components Analysis of Traditional Chinese Medicine， the Drugbank database， the Reactome database， and the Human protein reference database （HPRD）， the protein-protein interactions network （PPI） and the drug target network were built and resolved. The data was mined to discover the pharmacological effect. The anti- tumor activity of components from SHL was determined based on the nearest distance rule between the compounds and the nodes of network. And then， the anti-tumor effect of the MCCM was verified in vitro and in vivo. Result:The 3 combined compounds， baicalin， forsythoside A and chlorogenic acid with the anti-tumor activity from SHL were predicted and discovered. The verification results showed that the combination of baicalin-forsythoside A-chlorogenic acid could significantly inhibit the cell proliferation and migration compared with the control group in vitro （P<0.01）. Among CT26 bearing mice， the tumor volume and weight were significantly decreased after the combined administration of baicalin-forsythoside A-chlorogenic acid compared with the model group in vivo （P<0.01）. Conclusion:By the methods of network pharmacology， the anti-tumor activities of component of from SHL were discovered. According to the verification in vitro and in vivo， the combination of baicalin-forsythoside A-chlorogenic acid could play better anti-CT26 tumor activity.

Embryonic cardiogenesis requires precise expression of various genes.This process involves a complex model of gene regulation,in which any deviation will lead to the occurrence of heart defects.Expression of Tbx2 in different species is ultimately confined to the atrioventricular canal in the non-ventricular myocardium,suggesting that the temporal and spatial expression of Tbx2 gene during cardiac development is highly consistent and evolutionarily conserved.As a member of the T-box transcription factor family,Tbx2 plays an important role in the differentiation of outflow tract and atrioventricular canal,leading to a series of changes in the regulatory pathway by regulating the transcription levels of the downstream target genes.At present,more and more studies have indicated that aberrant expressions or regulations of Tbx2 result in cardiac malformations in different model animals.In clinical studies,microdeletions/duplications in the fragments involving TBX2 and genetic variants in the non-coding region of this gene have also been reported in human congenital heart defects.Thus,this article is to review the advances in the effect and possible mechanisms for Tbx2 gene in cardiac development,and to discuss the relationship between this gene and congenital heart defects.
ABSTRACT
As more and more studies suggest that type 2 diabetes mellitus (T2DM) is closely related to male hypogonadism, people begin to pay more attention to the role of testosterone in the development of T2DM and the effect and safety of testosterone supplementary therapy. There is some controversy in randomized controlled studies and meta-analyses about the effects of testosterone supplementation on the blood glucose level, androgen deficiency symptoms, and cardiovascular diseases. This review focuses on the diagnosis of hypogonadism in T2DM males, differences in the therapeutic effects and safety of testosterone replacement among different studies, and rational use of testosterone supplementation for T2DM patients.

AIM:To investigate the role of miR-125b in regulating the sensitivity of CD133+ colorectal cancer cells to cisplatin.METHODS:The expression of miR-125b was detected by RT-qPCR in the routine SW480 cells and CD133+ SW480 cells.Flow cytometry analysis was performed to measure the percentage of CD133+ cell population in the SW480 cell line treated with miR-125b and cisplatin.MTT assay was performed to evaluate the effect of miR-125b on the cisplatin-induced cell death in the CD133+ SW480 cells.Bioinformatics and Western blot were performed to determine whether the expression of HAX-1 was regulated by miR-125b.JC-1 staining, Annexin V staining and Western blot analysis were used to study the pathway of apoptosis in the CD133+ SW480 cells co-treated with miR-125b and cisplatin.RESULTS:The expression of miR-125b was significantly lower in the CD133+ SW480 cells than that in the routine SW480 cells and normal colonic epithelial FHC cells.Treatment with cisplatin alone increased the percentage of CD133+ SW480 cell population.However, miR-125b significantly inhibited the enrichment of CD133+ cell population induced by cisplatin.In addition, the results of MTT assay showed that the anti-tumor effect of cisplatin was significantly enhanced when the miR-125b was transfected into the CD133+ SW480 cells.The results of Western blot indicated that the HAX-1 gene was the target of miR-125b.Furthermore, the apoptosis induced by the combination of miR-125b and cisplatin was dependent on the dysfunction of mitochondrial membrane, leading to the release of cytochrome C into the cytoplasm and the subsequently activation of apoptosis in the CD133+ SW480 cells.CONCLUSION:miR-125b increased the sensitivity of CD133+ colo-rectal cancer cells to cisplatin by down-regulating the expression of HAX-1.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the role of long non-coding RNA growth arrest-specific transcript 5 (lncRNA-GAS5) in breast cancer progression and epithelial-mesenchymal transition (EMT) of the cancer cells.</p><p><b>METHODS</b>Real-time quantitative PCR (qRT-PCR) was used to detect the expression of lncRNA-GAS5 in 37 pairs of breast cancer and adjacent non-tumor tissues and in parental MCF-7 cells and paclitaxel-resistant MCF-7 (MCF-7/PR) cells, and the correlation of lncRNA-GAS5 expression with the clinical stage and lymph node metastasis of breast cancer was investigated. The expressions of the genes related with cell cycle and EMT at both the mRNA and protein levels were detected using qRT-PCR, Western blotting and immunohistochemistry. The changes in the biological behaviors and morphology of breast cancer cells with either lncRNA-GAS5 knockdown or overexpression were observed. Nude mouse models were established bearing breast cancer xenografts derived from MCF-7/PR cells or MCF-7/PR cells over-expressing lncRNA-GAS5, and the inhibitory effect of paclitaxel on tumor growth was evaluated.</p><p><b>RESULTS</b>The transcriptional levels of lncRNA-GAS5 were significantly lower in breast cancer tissues than in the adjacent non-tumor tissues (P<0.05), and decreased lncRNA-GAS5 expression was significantly correlated with TNM stage and lymph node metastasis of breast cancer (P<0.05). lncRNA-GAS5 expression was also significantly lowered in paclitaxel-resistant breast cancer cells and showed a positive correlation with P21 expression and a negative correlation with CDK6. MCF-7 cells during EMT presented with a lowered expression of lncRNA-GAS5, whereas lncRNA-GAS5 over-expression strongly suppressed MCF-7/PR cell migration and invasion, and increased the susceptibility of the cells to paclitaxel. In the tumor-bearing nude mouse models, lncRNA-GAS5 overexpression in the tumor cells obviously enhanced the inhibitory effect of paclitaxel on tumor growth and lung metastasis by reversing the EMT marker proteins.</p><p><b>CONCLUSION</b>A decreased expression of lncRNA-GAS5 promotes lung metastasis of breast cancer by inducing EMT, suggesting the potential of lncRNA-GAS5 as a therapeutic target in breast cancer.</p>
ABSTRACT
Objective To investigate the relationship of the cytogenetic abnormalities detected by FISH in patients with MM and their clinical features. Methods FISH on bone marrow (BM) cells was performed in 57 enrolled MM patients. Relationships between cytogenetic abnormalities and clinical features were analyzed. Results By statistical analysis , both D13S319 deletion and RB1 deletion were associated with high level of serum LDH (P = 0.024; P = 0.018) and BM plasma cells index (P = 0.027; P = 0.013). 1q21 amplification was significantly associated with high level of LDH (P = 0.030 ) and the occurence of light chain type myeloma (P = 0.023). IgH rearrangement was associated with renal function damage (P = 0.009). There were correlations among D13S319 deletion, RB1 deletion, 1q21 amplification and IgH rearrangement (P<0.01). Conclusion The genetic abnormalities detected by FISH in patients with MM were correlated with various clinical poor prognostic indicators, which can evaluate the condition and prognosis of patients more efficiently.
ABSTRACT
This research is to study the relationship between HPLC fingerprints of Moutan Cortex, Paeoniae Radix Rubra and Paeoniae Radix Alba and their activity on lipopolysaccharide-induced acute lung injury. HPLC fingerprints of each extract of Moutan Cortex,Paeoniae Radix Rubra and Paeoniae Radix Alba were established by an optimized HPLC-MS method. The activities of all samples against protein and tumor necrosis a factor were tested by the model of lipopolysaccharide-induced acute lung injury. The possible relationship between HPLC-MS fingerprints and the activitieswere deduced by the Partial least squares regression analysis method. Samples were analyzed by HPLC-MS/MS to identify the major peaks. The results showed that each sample had some effect on acute lung injury. Four components with a lager contribution rate of efficacy were calculated by the research of spectrum-effect relationship. Moutan Cortex exhibited good activity on acute lung injury, and gallic acid, paeoniflorin, galloylpaeoniflorin and paeonol were the main effective components.

Objective To investigate the appropriate cut-off point of CA19-9 level for predicting the prognosis of patients with hilar cholangiocarcinoma (HC) after radical surgery, and to discuss other potential prognostic factors that may affect their prognosis. Methods Totally 168 patients who had undergone radical surgery for HC in Eastern Hepatobiliary Surgery Hospital were selected for this study. The relationship of preoperation serum CA19-9 level with the clinicopathological characteristics of HC patientswas analyzed, and ROC curvewas used to determine the appropriate cut-off point of CA19-9 level. The potential factors influencing the prognosis were analyzed by univariate model and the independent factors were analyzed by multivariate methods. Results Preoperative serum CA19-9 levil was related to pathologic stage, lymph node metastasis, and tumor size in HC patients. The strongest univariate predictor among the categorized preoperative CA19-9 measures was CA19-9 levil less than 150 U/mL (P = 0. 000). Inunivariate analysis, the age, tumor size, differentiation degree, Bismuth-Corlette classification, portal vein invasion, hepatic artery invasion, liver invasion, preoperative biliary drainage, lymph node metastasis, and resection margin were identified as significant prognostic factorsof HC. Multivariable analysis showed that the differentiation degree, lymph node metastasis, hepatic artery invasion, resection margin and preoperative serum CA19-9 levil were the independent prognostic factors of HC, with the OR values and 95 %confidence intervil (Cl) being 3. 359 (1. 440-7. 837), 2. 973 (1. 927-4. 587), 2. 096 (1. 271-3. 455), 2. 238 (1. 356-3. 694), and 2. 954 (1. 890-4. 618), respectively. Conclusion Our results demonstrate that preoperative serum CA19-9 level is an independent prognostic factor for HC patients, and the most discriminative cut-off point of CA19-9 level for prognosis is 150 U/mL. The differentiation degree, lymph node metastasis, hepatic artery invasion, and resection marginare also the independent prognostic factors of HC.
