RESUMO
Objective:To investigate the expression level of poly ADP ribose polymerase 14(PARP14) in thyroid cancer and its relationship with the clinicopathologic characteristics of the patient with thyroid cancer and evaluate the role of PARP14 in the progression of thyroid cancer.Methods:The gene expression interaction analysis (GEPIA) database was used to analyze the expression of PARP14 in normal thyroid tissue and thyroid cancer tissue and its relationship with disease-free survival of patients. The expression of PARP14 in thyroid cancer tissue and adjacent tissues of the patient with thyroid cancer was evaluated by immunohistochemistry. According to the staining intensity, the patients were divided into the high expression group and the low expression group, and the correlation between the expression of PARP14 and clinical pathological characteristics was analyzed. The effect of PARP14 on the proliferation of thyroid cancer cells was investigated by clone formation testing and MTT testing.Results:The results of bioinformatics analysis and immunohistochemistry showed that PARP14 was overexpressed in thyroid cancer tissue, and the disease-free survival rate of the patient with high expression was lower. The expression level of PARP14 was correlated with tumor stage and intrathyroidal spread (all P<0.05). The results of the clonogenic assay and the MTT assay showed that the expression of KIF4A could promote the proliferation of thyroid cancer cells ( P<0.05). Conclusions:PARP14 is highly expressed in thyroid cancer and is related to the clinicopathological characteristics of patients, suggesting that it may be a therapeutic target for thyroid cancer.

RESUMO
Thrombospondin 4 (THBS4), a member of the THBS family, is a protein secreted by the extracellular matrix and is involved in regulating various physiological processes, such as cell proliferation, adhesion and angiogenesis. Recent studies have shown that the inflammation stimulates THBS4 production and induces the adhesion and accumulation of macrophages. Our previous study confirmed that THBS4 acts as an oncogene in hepatocellular carcinoma (HCC), the effect of THBS4 on the immune microenvironment of HCC remains unclear. This study aims to analyze the role of THBS4 in promoting the metastasis of HCC cells by inducing M2-type polarization of tumor-associated macrophages. We simulate the tumor microenvironment through HCC conditioned medium (HCM) and found that the expression of THBS4 in macrophages increased in a time-dependent manner under the action of HCM (P<0.05); THBS4 knockdown promotes the expression of M1 macrophages markers IL-1β and CD86 (P<0.01), while the expression of M2-type markers IL-10 and CD206 were decreased (P<0.01). Transwell co-culture assay was used to further detect the effect of THBS4-induced M2-type macrophages on HCC metastasis. Results from co-culture of THBS4-downregulated M2 macrophages with HepG2 cells showed that THBS4-downregulated M2-TAMs significantly inhibited the invasion and migration ability of HepG2 cells (all P < 0.01). In conclusion, the tumor microenvironment promotes the expression of THBS4 in macrophages, and THBS4 may promote the invasion and metastasis of HCC cells by inducing M2-type polarization of macrophages. This study provides some new experimental basis for exploring the establishment of THBS4-induced HCC immune microenvironment.
RESUMO
【Objective】 To study the role and mechanism of sinomenine in the macrophage polarization induced by gastric cancer cells. 【Methods】 Sinomenine was added to gastric cancer cells BGC-823 and MKN-45， cell viability was measured by CCK-8， cell proliferation was measured by colony formation experiment， Co-culture and Transwell cell migration experiments were used to evaluate the recruitment and polarization of macrophages by sinomenine， flow cytometry was used to evaluate the polarization of macrophages， and qRT-PCR and Western blot were used to detect the expression of gene RNA and protein levels. 【Results】 Sinomenine could inhibit the proliferation of gastric cancer cells and the recruitment of gastric cancer cells to macrophages， thus promoting macrophage M2 polarization. It simultaneously inhibited the expression of STAT6 as well as the expression and phosphorylation of C/EBPβ. When STAT6 is overexpressed， it could reduce these inhibitory effects of sinomenine on gastric cancer cells. Further research found that STAT6 mediated the secretion of IL-6 by gastric cancer cells， which was the cause of sinomenine-mediated macrophage recruitment and M2 polarization. 【Conclusion】 The natural drug sinomenine has a good tumor-suppressing ability against gastric cancer， directly inhibits the survival and migration of gastric cancer cells， and inhibits the expression of IL-6 and the M2 phenotype in the tumor microenvironment， reshapes the tumor environment， and reduces the risk of M2 type macrophages for gastric cancer tumors.
RESUMO
Objective: To investigate the effects of Zhongfeng capsule on the autophagy-related proteins expression in rats with cerebral ischemia/reperfusion injury (CI/ RI), and to explore its neural protection mechanisms of the decoction. Methods: Rat middle cerebral artery ischemia/reperfusion injury model (ischemia for 2 h, reperfusion for 24 h) was prepared by the improved line plug method. Sixty male SD rats were randomly divided into sham operation group, model group, butylphthalide group(0.054 g/kg), Zhongfeng capsule high-dose groups (1.08 g/kg), Zhongfeng capsule middle-dose groups (0.54 g/kg), Zhongfeng capsule low-dose groups (0.27 g/kg), with 10 rats in each group. Rats were treated with Zhongfeng capsule by gavage once a day for 10 days. The rats were sacrificed and the brain tissue was obtained after the experiment in each group. Score neurological deficit was evaluated after 24 h of the last intervention in rat of each group. The pathological changes of brain tissue were observed by HE staining. The serum levels of estradiol (E2) and follicle stimulating hormone (FSH) were determined by ELISA. The expressions of key genes and proteins of PI3K/Akt/Beclin1 signaling pathway in brain tissue were detected by qRT-PCR and Western blot respectively. Results: Compared with the sham operation group, the body weight and protein expressions of p-PI3k and p-Akt in brain tissue of rats were decreased significantly in the model group, while the brain index, neurological deficit score, gene and protein expressions of Beclin1 and LC3 were increased markedly in the model group(P＜0.05 or P＜0.01). In the model group, nerve cells of brain tissue were loosely packed, interstitial edema, triangular in shape, nuclear pyknosis and dark-blue staining were observed. Compared with the model group, the body weight of rats was increased obviously, the neurological deficit score was decreased significantly and the pathological injury of brain tissue was alleviated evidently in high-dose of Zhongfeng capsule group (P＜0.05). The brain index, the gene and protein expressions of Beclin1 and LC3 were decreased apparently in Zhongfeng capsule treatment groups(P＜0.05 or P＜0.01), while the expressions of p-PI3k and p-Akt in brain tissue were increased evidently in Zhongfeng capsule treatment groups(P＜0.05 or P＜0.01). Conclusion: Zhongfeng capsule can inhibit autophagy and improve brain neurons lesion of CIRI rats, the mechanism may be related to regulate the expression of Beclin1 and LC3 in PI3K/Akt/Beclin1 signaling pathway.

Objective: To study the expression and effect of small nuclear ribonucleoprotein-associated protein B (SNRPB) on proliferation and metastasis of liver cancer tissues and cells. Methods: The bioinformatics database starBase v3.0 and GEPIA were used to analyze the expression of SNRPB in liver cancer tissue and normal liver tissue, as well as the survival and prognosis of liver cancer patients. The expression of SNRPB mRNA and protein in liver cancer cell lines were analyzed by qRT-PCR and Western blot. RNA interference technique (siRNA) was used to determine SNRPB protein expression down-regulation. The proliferation effect on hepatocellular carcinoma cells was observed by MTT assay. Transwell invasion and migration assay was used to detect the changes in the metastatic ability of liver cancer cells after SNRPB down-regulation. Western blot was used to detect the changes of epithelial mesenchymal transition (EMT) markers in liver cancer cells after down-regulation of SNRPB expression. Data were compared between two groups and multiple groups using t-test and analysis of variance. Results: The expression of SNRPB was significantly higher in liver cancer tissue than normal liver tissue, and its expression level was correlated with the prognosis of liver cancer patients. Compared with the immortalized hepatocyte LO(2), the expression of SNRPB was significantly increased in the liver cancer cells (P < 0.01). siRNA-SNRPB had significantly inhibited the expression of SNRPB mRNA and protein in liver cancer cells. MTT results showed that the absorbance value was lower in SNRPB knockdown group than negative control group, and the difference at 96 h after transfection was most significant (P < 0.01). Transwell assay results showed that compared with the negative control group, the SNRPB knockdown group (MHCC-97H: 121.27 ± 8.12 vs. 46.38 ± 7.54; Huh7: 126.50 ± 6.98 vs. 41.10 ± 8.01) invasion and migration (MHCC-97H: 125.20 ± 4.77 vs. 43.18 ± 7.32; Huh7: 132.22 ± 8.21 vs. 38.00 ± 6.78) ability was significantly reduced (P < 0.01) in liver cancer cells. Western blot showed that the expression level of epithelial phenotype marker E-cadherin was decreased after down-regulation of SNRPB, while the expression levels of mesenchymal phenotype markers N-cadherin and vimentin was increased, suggesting that down-regulation of SNRPB inhibited EMT in liver cancer cells. Conclusion: SNRPB expression is significantly increased in liver cancer tissues and cells, and it is involved in regulating the proliferation, metastasis and EMT of liver cancer cells.

G-quadruplex (G4) is a non-canonical nucleic acid secondary structure composed of guanine-rich DNA or RNA sequences. In the past few decades, researchers have focused on the G-rich sequences in gene promoter region, UTR, telomere and other common gene functional regions, to understand the relationship between their structure and function. In recent years, due to the in-depth study of non-coding RNA in diseases, G-rich sequences in non-coding RNA, especially miRNA, have attracted more attention. G-rich sequence has been involved in all physiological processes of miRNA synthesis, from primary miRNA (pri-miRNA), precursor miRNA (pre-miRNA) to mature miRNA: the dynamic balance formed between the G-quadruplex and the RNA stem-loop structure affects the maturation process of primary and precursor miRNA, causing the change of mature miRNA and the complementary pairing between miRNA and mRNA. This review focused on the dynamic changes between G4 and hairpin structure, and expounded the role of G-rich sequence in pri-miRNA, pre-miRNA, mature miRNA and mRNA. The important role of G-quadruplex in the maturation and function of miRNA was also discussed. It was concluded that the changes of external regulatory factors such as ionic conditions (K+, Mg +, K+ + Mg, Li +Mg +, etc) and G-quadruplex ligand molecules (destabilizer TMPyP4, etc) could regulate the balance between G-quadruplex and stem-loop structure, thus modulating the functions of miRNA. This review may help providing ideas and directions for the study of G-quadruplex function and regulation.
RESUMO
Objective:To explore the expression of polypyrimidine tract-binding protein 1 (PTBP1) in gastric cancer (GC) tissues and GC cell lines, and the role of PTBP1 in the proliferation and metastasis of GC cells.Methods:From January to June in 2019 at The First Affiliated Hospital of Xi′an Jiaotong University, the cancer tissues and corresponding para-cancer tissues of GC patients underwent surgical resection were collected. The Kaplan-Meier Plotter database was used to analyze the survival of GC patients. The expression of PTBP1 was down-regulated by transfecting small interfering RNA (siRNA) in human GC cell lines SGC7901 and AGS with relatively high expression of PTBP1. The cells were divided into blank control group, negative control group, and PTBP1 knockdown group. The expression of PTBP1 at mRNA and protein level were detected by real-time fluorescence quantification polymerase chain reaction (RT-qPCR) and Western blotting. At 24, 48, 72 and 96-hour after transfection, the effect of PTBP1 on the proliferation of GC cells was observed by 3-(4, 5 dimethylthiazol)-2, 5 diphenyltetrazolium bromide (MTT) experiment. The changes of invasion and migration of GC cells after down-regulation of PTBP1 were detected by transwell assay. The expression changes of epithelial-mesenchymal transition (EMT) markers E-cadherin, N-cadherin and vimentin after down-regulation of PTBP1 in GC cells were determined by Western blotting. Indenpendent samples t test, analysis of variance and rank sum test were used for statistical analysis. Results:The Kaplan-Meier Plotter prognostic analysis showed that the overall survival of GC patients with high PTBP1 expression was shorter than that of GC patients with low PTBP1 expression (9.2 months, 6.2 months to 17.2 months vs. 19.0 months, 14.5 months to 28.4 months), and the difference was statistically significant ( Z=5.31, P<0.05). The results of RT-qPCR showed that in GC cell lines SGC7901 and AGS, the expression of PTBP1 at mRNA level of PTBP1 knockdown group was lower than that of blank control group and negative control group (SGC7901: 0.78±0.11 vs.3.10±0.19 and 2.99±0.23; AGS: 0.80±0.09 vs. 3.55±0.24 and 3.50±0.18), and the differences were statistically significant ( tSGC7901=10.57 and 8.08, tAGS=10.91 and 13.42; all P<0.01). The results of Western blotting indicated that in GC cell lines SGC7901 and AGS, the expression of PTBP1 at protein level of PTBP1 knockdown group was lower than those of blank control group and negative control group (SGC7901: 0.38±0.04 vs. 1.42±0.05 and 1.35±0.09; AGS: 0.17±0.02 vs. 1.52±0.08 and 1.38±0.45), and the differences were statistically significant ( tSGC7901=15.94 and 10.57, tAGS=16.60 and 20.80; all P<0.01). The results of MTT showed that at 48, 72 and 96-hour after transfection the absorbance values of PTBP1 knockdown group decreased by 0.25±0.01, 0.38±0.02, and 0.84±0.04 as compared with those of negative control group, and the decrease was the most significant at 96-hour after transfection, and the differences were statistically significant ( t=10.21、14.32, both P<0.01). The results of transwell experiment demonstrated that the number of invasion and migration cells of PTBP1 knockdown group were both less than that of the blank control group and the negative control group (SGC7901: 42.00±5.91 vs. 116.40±10.23 and 114.40±10.43; 39.60±6.77 vs. 125.80±11.51 and 122.40±5.90; AGS: 40.20±7.25 vs. 115.60±14.63 and 117.40±9.12; 36.00±5.20 vs. 122.40±12.10 and 125.40±12.74), and the differences were statistically significant ( tSGC7901=14.07, 13.50, 14.43 and 20.62; tAGS=10.27, 14.75, 14.68 and 16.76; all P<0.01). The results of Western blotting showed that the expression of E-cadherin of PTBP1 knockdown group was higher than that of the blank control group and the negative control group (SGC7901: 1.42±0.05 vs. 0.53±0.05 and 0.57±0.03; AGS: 1.34±0.04 vs. 0.54±0.03 and 0.61±0.01), however the expression levels of N-cadherin and vimentin were both lower than those of the blank control group and the negative control group (SGC7901: 0.50±0.03 vs. 1.64±0.05 and 1.46±0.07; 0.32±0.07 vs. 1.42±0.07 and 1.33±0.07; AGS: 0.37±0.06 vs. 1.47±0.04 and 1.36±0.04; 0.41±0.04 vs. 1.53±0.06 and 1.37±0.04), and the differences were statistically significant ( tSGC7901=11.63, 13.19, 18.83, 11.68, 11.43 and 10.43; tAGS= 15.02, 16.23, 14.67, 12.97, 14.45 and 17.18; all P<0.01). Conclusions:The expression levels of PTBP1 increase in GC tissues and cells, which may be involved in regulating the proliferation, metastasis and EMT of GC cells.

Among them, 35 patients were treated with injured vertebra pedicle fixation combined with vertebroplasty (group A), including 20 males and 15 females, aged from 55 to 74 years with an average of (64.03± 7.82) years. Twenty-six cases were type A3 and 9 cases were type A4 according to the AO typing;another 35 patients were treated with short segment pedicle screw fixation combined with vertebroplasty (group B), including 18 males and 17 females, aged from 54 to 72 years with an average of (62.78±6.40) years. Twenty-eight cases were type A3 and 7 cases were type A4 according to AO typing. Operation length, intraoperative bleeding volume, complication, imaging parameters and clinical effects were compared between the two groups.@*RESULTS@#All the patients were followed up for at least 12 months. There were no significant differences in gender, age, injury site, preoperative VAS, Cobb angle, and injured vertebral height before surgery. There were no significant differences in operation length, intraoperative bleeding volume between two groups. In terms of VAS scores before surgery, 1 week after surgery, and at the final follow up, group A was 5.5 ±2.5, 1.8 ±0.8, 0.9 ±0.4, group B was 5.4 ± 2.3, 1.7±0.6, 1.2±1.8, respectively;injured vertebral height was (40.4±8.8)%, (92.0±4.9)%, (87.1±3.8)% in group A, and (41.2±6.6)%, (93.2±4.6)%, (80.0±4.3)% in group B;Cobb angle was (18.4±6.9) °, (2.8±2.2) °, (4.2±2.6) ° in group A, and (16.8±7.2) °, (2.7±2.5) °, (6.0±2.4) ° in group B. There were significant differences in the 3 parameters above before the operation and at the final follow up in all groups (<0.05). There were significant differences in the Cobb angle and injured vertebral height between 1 week after operation and at the final follow up (<0.05). At the final follow up, injured vertebral height in group A was obviously better than that in group B (<0.05). Internal fixation failure occurred in 2 cases from the group A, and occurred in 4 cases from the group B. There were no neurological complications in both groups.@*CONCLUSION@#For osteoporotic thoracolumbar vertebral burst fractures, injured vertebra pedicle fixation combined with vertebroplasty and vertebra pedicle screw fixation combined with vertebroplasty can achieve good clinical effects. However, injured vertebra pedicle fixation combined with vertebroplasty is better at maintaining postoperative vertebral height and sagittal arrangement, and reducing internal fixation related complications. The treatment strategy is worthy of application and promotion.

RESUMO
A boy, aged 66 days, was admitted to the hospital due to subcutaneous nodules for 46 days and abdominal distension for 10 days. The main clinical manifestations were loss of adipose tissue, subcutaneous nodules, insulin-resistant diabetes, hypertriglyceridemia, and hepatic steatosis. The boy was diagnosed with congenital generalized lipodystrophy type 1 (CGL1). His condition was improved after administration of middle-chain fatty acid formula milk and insulin injection or oral metformin. Gene testing revealed a homozygous mutation, c.646A>T, in the AGPAT2 gene, and both his parents were carriers of this mutation. This case of CGL1 has the youngest age of onset ever reported in China and multiple subcutaneous nodules as the initial symptom.

RESUMO
Objective:To explore the hepatoprotective effect and its mechanism of the geraniin on mice with acute liver injury induced by D-galactosamine (D-GalN). Method:A total of 60 Kunming mice were randomly divided into normal group, model group, Silymarin group (positive group 180 mg·kg-1), and low, medium and high-dose geraniin groups (50, 100, 200 mg·kg-1). All the mice were given with saline or corresponding dose of drugs (10 mL·kg-1) by gavage once a day for 10 d. After 2 h of the last administration, except the normal group, the mice of other groups were injected intraperitoneally with D-GalN (500 mg·kg-1) to induce the acute liver injury. After 16 h, the eye balls of mice were removed to take blood, and all mice were put to death to collect samples of liver. Activity or content of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), total bilirubin (TBIL), malondialdehyde (MDA), total superoxide dismutase (T-SOD) and glutathione peroxidase (GSH-Px) in liver were determined by biochemical method. The serum levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), γ-interferon (IFN-γ) and interleukin-6 (IL-6) were detected by enzyme-linked immunosorbent assay (ELISA), and expressions of Toll-like receptor-4(TLR-4) and nuclear factor(NF)-κB proteins were detected by Western blot. Liver histopathological changes were observed by hematoxylin-eosin (HE) staining. Result:Compared with the normal group, the serum levels of ALT, AST, ALP, TBIL and liver MDA in the model group were significantly increased (PPPPPPα, IL-1β, IL-6, IFN-γ and the expressions of TLR-4 and NF-κB proteins in serum (PPConclusion:Geraniin has an obvious protective effective on acute liver injuries induced by D-GalN in mice. Its mechanism may be correlated with oxidative stress, inflammation and TLR-4/NF-κB signaling pathway.
RESUMO
Objective: To detect the methylation levels of homeobox protein Hox A7 (HOXA7) gene promoter in the plasma of non-small cell lung cancer (NSCLC) and to study the value of HOXA7 methylation and serum levels of the tumor markers carcinoembryonic antigen (CEA), carbohydrate antigen 199 (CA199), and cytokeratin 19 fragment (Cyfra21-1) in the auxiliary diagnosis of NSCLC. Methods: Plasma samples were collected from 80 patients with NSCLC and 50 healthy controls, which were enrolled in Henan Cancer Hospital from January 2012 to December 2016. The plasma HOXA7 methylation levels were detected by real-time quantitative methylation-specific PCR, and the plasma levels of CEA, CA199, and Cyfra21-1 were detected by electrochemical luminescence. The ROC curve was constructed to analyze the clinical value of each index in the differential diagnosis of NSCLC, and the relationship between HOXA7 methylation, clinical parameters, and tumor markers was analyzed. Results: The serum levels of HOXA7 methylation in NSCLC patients were significantly higher (χ2=36.972, P<0.000 1) than the healthy control group. The sensitivity and specificity of HOXA7 methylation in the diagnosis of NSCLC were 68.8% (55/80) and 86.0% (43/50), respectively. Plasma HOXA7 methylation was not related to gender, age, smoking history, or pathological type (all P>0.05), but was related to TNM stage (P<0.05). The plasma HOXA7 methylation level of stageⅣpatients (81.8%, 18/22) was the highest. Cyfra21-1 had the highest value in the diagnosis of NSCLC among tumor markers with a sensitivity of 70.00% and a specificity of 90.00%. The combination of HOXA7 methylation with all three tumor markers had the highest efficiency (AUC=0.893, sensitivity 73.75%, specificity 94%) in the diagnosis of NSCLC. The correlation coefficient between HOXA7 methylation and Cyfra21-1 was the highest (r=0.564, P<0.05). Conclusions: HOXA7 gene methylation is related to the degree of metastasis of NSCLC and proves as an efficient diagnostic marker for NSCLC when combined with tumor marker detection.
RESUMO
In this study, 13 xyloglucan endotransglycosylases/hydrolases (XTHs) and 8 expansin (EXPs) were screened from safflower floret transcriptome database. Through correlation analysis between the safflower gene expression profile chip and the corolla development, only 4 XTHs (CtXTH1-4) and 1 EXP (CtEXP1) have positive relevance with corolla elongation (r≥0.60) and were therefore validated by qRT-PCR. The full length of these genes were cloned by RACE. According to the bioinformatic analysis, CtXTH1 correlated with the development of the floret, and the expression pattern analysis indicated that CtXTH1 had accumulated in the floret. The recombinant vector (pMT39-CtXTH1) was constructed for gene transformation. Overexpression of CtXTH1 significantly increased the corolla length (about 5.34% to 10.25%) and corolla weight (about 30.00% to 36.02%) in transgenic safflower. The overexpression lines also showed an increasing tendency in the weight of seeds, average number of corollas per cone and average number of seeds in each cone. Meanwhile, overexpression of CtXTH1 had no significant effect on flavonoids. According to the corolla microstructure, the OVX-line tubular part of floret exhibited a looser and irregular character. These data suggested that CtXTH1 can potentially increase relaxation of the tissues and boost corolla elongation. Our study provides a valuable clue for plant breeding in the future.
