RESUMO

Background: The aim of this study was to explore the diagnostic and therapeutic performances of the artificial intelligence (AI), American College of Radiology (ACR), and Kwak Thyroid Imaging Reporting and Data Systems (TIRADSs) using the size thresholds for fine needle aspiration (FNA) and follow-up defined in the ACR TIRADS. Methods: This retrospective study included 3,833 consecutive thyroid nodules identified in 2,590 patients from January 2010 to August 2017. Ultrasound (US) features were reviewed using the 2017 white paper of the ACR TIRADS. US categories were assigned according to the ACR/AI and Kwak TIRADS. We applied the thresholds for FNA and follow-up defined in the ACR TIRADS to the Kwak TIRADS. The diagnostic and therapeutic performances were calculated and compared using the McNemar or DeLong methods. Results: The AI TIRADS had higher specificity, accuracy, and area under the curve (AUC) than did the ACR and Kwak TIRADS (specificity: 64.6% vs. 57.4% and 52.69%; accuracy: 78.5% vs. 75.4% and 73.0%; AUC: 88.2% vs. 86.6% and 86.0%; all P values <0.05). Meanwhile, the AI TIRADS had a lower FNA rate (FNAR), unnecessary FNA rate (UFR), and follow-up rate (FUR) than did the ACR and Kwak TIRADS using the size thresholds of the ACR TIRADS (specificity: 30.9% vs. 34.4% and 36.9%; accuracy: 41.1% vs. 47.8% and 48.7%; AUC: 34.2% vs. 37.7% and 41.0%; all P values <0.05). In addition, the Kwak TIRADS incorporating the size thresholds of the ACR TIRADS was almost similar to the ACR TIRADS in diagnostic and therapeutical performance. Conclusions: The ACR TIRADS can be simplified, which potentially enhances its diagnostic and therapeutic performance. The method of score-based TIRADS (counting in the Kwak TIRADS and weighting in the ACR and AI TIRADS) might not determine the diagnostic and therapeutic performances of the TIRADS. Thus, we propose choosing a straightforward and practical TIRADS in daily practice.

RESUMO

ObjectiveTo explore the effect of Danggui Niantongtang (DGNTT) on cell apoptosis and autophagy in rheumatoid arthritis (RA) fibroblast-like synoviocytes (FLS). MethodRA-FLS were isolated and cultured from the synovial tissue of RA patients. The cells were treated with 10% blank serum (blank control group), 10% sera containing low, medium and high doses of DGNTT. Wound healing assa and cell invasion test were applied to observe the effect of RA-FLS invasion technique. The apoptosis and autophagy level of RA-FLS cells was detected by Hoechst33342 method and monodansylcadaverine (MDC) staining. The mRNA and protein expression levels of B cell lymphoma-2 (Bcl-2), Bcl-2 associated X protein (Bax), microtubule-associated protein 1 light chain 3 (LC3), autophagy key molecular yeast Atg6 homolog 1 (Beclin1) were detected by Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR)and Western blot. ResultCompared with the blank control group,each dose of serum could slow down the wound healing and significantly Reduce the number of RA-FLS cells invading the lower chamber(P<0.01),the mRNA and protein expression levels of Bcl-2,LC3,Beclin1 were significantly decreased(P<0.01), and Bax were significantly increased(P<0.01). Hoechst33342 results showed that low, medium and high doses DGNTT could promote RA-FLS cell apoptosis. After MDC staining,autophagosome in low, medium and high doses DGNTT decreased significantly(P<0.01). ConclusionDanggui Niantongtang can effectively inhibit the proliferation of fibroblast-like synoviocytes. Its mechanism may be related to promote apoptosis and inhibit autophagy of fibroblast-like synoviocytes.

RESUMO

ObjectiveTo observe the preventive and control effects of Danggui Niantongtang against adjuvant arthritis differentiated into wind-damp-heat impediment in rats and its influences on the expression of autophagy-related proteins microtubule-associated protein 1 light chain 3 (LC3), homolog of yeast Atg6 (Beclin1) and p62. MethodThe six-week-old male SD rats were randomly divided into the normal group, wind-damp-heat impediment model group, low-, medium-, and high-dose Danggui Niantongtang (5.67, 11.34, 22.68 g·kg-1) groups, and methotrexate (MTX, 1.35 mg·kg-1) group, with 10 rats in each group. A rat model of adjuvant arthritis was established by subcutaneous injection of inactivated Mycobacterium tuberculosis into the tail root, followed by exposure to the manual climatic box for 16 d for inducing the wind-damp-heat impediment. The drugs were administered intragastrically on the day of immunization for 28 d. The general conditions of rats were observed and the swelling degree of toes and arthritis index (AI) were detected. The pathological changes in the synovial tissues of the knee joints were observed by hematoxylin-eosin (HE) staining. The mRNA expression levels of LC3, Beclin1, and p62 in the synovial tissues were measured by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR), followed by the assay of their protein expression by Western blot and immunohistochemistry. ResultCompared with the normal group, the wind-damp-heat impediment model group exhibited significantly increased swelling degree of toes (P<0.01), increased AI (P<0.01), proliferated synovial cells (P<0.01), up-regulated LC3 and Beclin1 protein and mRNA expression (P<0.01), and down-regulated p62 protein and mRNA expression (P<0.01) after 16, 20, 24, 28-d medication. Compared with the wind-damp-heat impediment model group, each medication group displayed alleviated toe swelling and synovial hyperplasia to different degrees, decreased mRNA and protein expression levels of LC3 and Beclin1 (P<0.01), and increased p62 mRNA and protein expression (P<0.05,P<0.01), with the best outcomes observed in the medium-dose Danggui Niantongtang group. ConclusionDanggui Niantongtang effectively relieves adjuvant arthritis due to wind-damp-heat impediment in rats, which may be related to its regulation of the expression of autophagy-related proteins LC3, Beclin1, and p62 and the inhibition of autophagy.

RESUMO

Three decades of research have documented the spatiotemporal dynamics of RHO family GTPase membrane extraction regulated by guanine nucleotide dissociation inhibitors (GDIs), but the interplay of the kinetic mechanism and structural specificity of these interactions is as yet unresolved. To address this, we reconstituted the GDI-controlled spatial segregation of geranylgeranylated RHO protein RAC1 in vitro. Various biochemical and biophysical measurements provided unprecedented mechanistic details for GDI function with respect to RHO protein dynamics. We determined that membrane extraction of RHO GTPases by GDI occurs via a 3-step mechanism: (1) GDI non-specifically associates with the switch regions of the RHO GTPases; (2) an electrostatic switch determines the interaction specificity between the C-terminal polybasic region of RHO GTPases and two distinct negatively-charged clusters of GDI1; (3) a non-specific displacement of geranylgeranyl moiety from the membrane sequesters it into a hydrophobic cleft, effectively shielding it from the aqueous milieu. This study substantially extends the model for the mechanism of GDI-regulated RHO GTPase extraction from the membrane, and could have implications for clinical studies and drug development.

RESUMO

Behcet′s disease is a chronic, multisystemic, inflammatory disease characterized by recurrent episodes of mucous membranes, eyes, musculoskeletal, blood vessels, central nervous system, and gastrointestinal tract.The treatment of Behcet′s disease varies according to the degree of organ involvement, gender and age of the patient, and there is no standard treatment. Behcet′s disease can be divided into vascular type, gastrointestinal type and neural type. Vascular type often leads to high mortality and disability rate.Glucocorticoids, azathioprine and cyclophosphamide are still recommended as first-line treatments for vascular Behcet′s disease.However, with the use of tumor necrosis factor inhibitors, they are an acceptable option for the treatment of refractory vascular Bezier′s disease.This article reviews the current treatment of vascular Behcet′s disease.

RESUMO

Objective:To observe the effect of Danggui Niantongtang on the protein and mRNA expression of key regulatory factors of the extrinsic and intrinsic apoptotic pathway in synovial tissue of adjuvant arthritis (AA) rats, and to further explore the mechanism of Danggui Niantongtang in the prevention and treatment of rheumatoid arthritis. Method:The general condition of AA rats, including its body weight, were observed. The changes of toe volume were detected by toe volume meter. Histopathological changes of synovium of knee joint were observed by hematoxylin-eosin (HE) staining. The mRNA and protein expression levels of tumor necrosis factor receptor super family 6 (Fas), Fas-associating protein with a novel death domain(FADD), B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax) and cysteinyl aspartate specific proteinase Caspase-3 (Caspase-3) were detected by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot. Result:Compared with the normal group, the toe volume of the model group increased significantly (<italic>P</italic><0.01), with significantly proliferated synovial cells, significantly reduced mRNA and protein expression levels of Fas, FADD, Bax and Caspase-3 in synovial tissues(<italic>P</italic><0.05,<italic> P</italic><0.01), and significantly increased Bcl-2 level (<italic>P</italic><0.01). Compared with the model group, the swelling degree of toes in Danggui Niantongtang group and Tripterygium group was significantly alleviated (<italic>P</italic><0.01), with significantly improved synovial hyperplasia, significantly increased mRNA and protein expression levels of Fas, FADD, Bax and Caspase-3 (<italic>P</italic><0.05, <italic>P</italic><0.01), and significantly decreased expression levels of bcl-2 mRNA and protein (<italic>P</italic><0.05, <italic>P</italic><0.01). Conclusion:Danggui Niantongtang can effectively reduce joint swelling and abnormal proliferation of synovial tissue in AA rats. Its mechanism may be related to regulating the expression of Fas, FADD, Bax, Bcl-2 and Caspase-3, and promoting the apoptosis of synovial cells.

RESUMO

Hepatocellular carcinoma(HCC) is the most common malignancy in the world. Although there is progress in HCC diagnosis and treatment, it is still the third leading cause of cancer death worldwide because it is not easily diagnosed early and the disease progresses quickly. China is a high-risk area for HCC, and the number of cases is high and on the rise. Its prevention and treatment is a pressing problem. At present, western medicine is still unclear about the complex pathogenesis and clinical treatment of HCC. There are still many shortcomings and huge challenges. Traditional Chinese medicine(TCM) has its unique advantages in the treatment of HCC. With an overall concept, it has unique therapeutic effect and fewer side effect on HCC,it can not only inhibit tumor growth, but also alleviate patients' clinical symptoms and improve their quality of life. Therefore, the study of the effect of TCM in treating HCC has attracted the attention from many clinicians and researchers. However, the chemical composition of TCM formula is complex, with many targets and huge network of pharmacodynamic mechanisms, which greatly limits the research on the development of clinical drugs for the Chinese medicine formula. In recent years, there have been achievements in the studies of anti-hepatocarcinoma efficacy and mechanism of action of Chinese medicine compound, which mainly focused on the compound's effect in inhibiting the proliferation of hepatocarcinoma cells, blocking cell cycle and inducing apoptosis and autophagy, inhibiting liver cancer cell invasion and metastasis, regulating the immune function, synergism and attenuation, and reversing the drug resistance. In this paper, domestic and foreign literatures on the above-mentioned pharmacodynamics and mechanism of anti-liver cancer of TCM compound were studied, analyzed, summarized and summarized. This paper briefly reviews the research progress of its anti-hepatocarcinoma mechanism, and provides scientific ideas and evidence for the future study of the anti-hepatocarcinoma mechanism of TCM compound and its rational clinical application.

RESUMO

Resistance to cisplatin (DDP)-based chemotherapy is a major cause of treatment failure in human gastric cancer (GC). It is necessary to identify the drugs to re-sensitize GC cells to DDP. In our previous research, Zuo Jin Wan Formula (ZJW) has been proved could increase the mitochondrial apoptosis via cofilin-1 in a immortalized cell line, SGC-7901/DDP. Due to the immortalized cells may still difficult highly recapitulate the important molecular events in vivo, primary GC cells model derived from clinical patient was constructed in the present study to further evaluate the effect of ZJW and the underlying molecular mechanism. Immunofluorescent staining was used to indentify primary cultured human GC cells. Western blotting was carried out to detect the protein expression. Cell Counting Kit-8 (CCK-8) was used to evaluate cell proliferation. Flow cytometry analysis was performed to assess cell apoptosis. ZJW inhibited proliferation and induced apoptosis in primary DDP-resistant GC cells. Notably, the apoptosis in GC cells was mediated by inducing cofilin-1 mitochondrial translocation, down-regulating Bcl-2 and up-regulating Bax expression. Surprisingly, the level of p-AKT protein was higher in DDP-resistant GC cells than that of the DDP-sensitive GC cells, and the activation of AKT could attenuate ZJW-induced sensitivity to DDP. These data revealed that ZJW can increase the chemosensitivity in DDP-resistant primary GC cells by inducing mitochondrial apoptosis and AKT inactivation. The combining chemotherapy with ZJW may be an effective therapeutic strategy for GC chemoresistance patients.

RESUMO

Malignant tumors of the digestive system , with high morbidity and mortality rate , are insidious at the onset and lack of effective treatments so far .Interleukin-22 (IL-22) is one of the members of the IL-10 cytokine family discovered in recent years and was originally called IL-10-associated T cell differentiation inducing factor (IL-TIF).IL-22 expression is elevated in various digestive system malignant tumors, and increased IL-22 expression is associated with tumor progression and poor prognosis .Studies on the molecular mechanism revealed that IL-22 initiates a series of downstream signaling pathways such as JAK/STAT and MAPK, by acting on the IL-22 receptor, inducing tumorigenesis.IL-22 is expected to be a novel diagnostic biomarker and therapeutic target of digestive system malignant tumor .

RESUMO

Gastric cancer, a common malignant tumor in digestive system with high morbidity as well as mortality rate, is insidious at the onset and lack of effective treatments so far. A growing number of studies have shown that exosome-derived miRNAs play an important role in the occurrence and development of gastric cancer. Autocrine exosome miRNAs from gastric cancer cells regulated tumor growth, recurrence, metastasis and drug resistance, etc. Moreover, exosomal miRNAs in the tumor microenvironment can be delivered into cancer cells to facilitate intercellular communication, thus affecting the progress of gastric cancer. Due to exosomes, which were released into circulation from tumor cells, contain abundant, specific and stable miRNAs, exosome-derived miRNAs have a great potential to be used as novel diagnosis biomarkers and treatment targets of gastric cancer.(Chin J Lab Med, 2018, 41: 499-502)

RESUMO

We previously demonstrated thatprenatal caffeine exposure (PCE) suppressed fetal adrenal steroidogenesis and resulted in developmental programming changes in offspring rats. However, whether these changes play a role in adrenal corticosterone synthesis under high-fat diet (HFD) and unpredictable chronic stress (UCS) remains unknown. In present study, rat model was established by PCE (120 mg/kg.d), and male offspring were provided normal diet or HFD after weaning. At postnatal week 21, several rats fed HFD were exposed to UCS for 3 weeks and sacrificed. The results showed that compared with the corresponding control group, the serum corticosterone levels and adrenal steroid synthetase expression of the PCE offspring without UCS were reduced. Moreover, the glucocorticoid (GC)-activation system was inhibited, and insulin-like growth factor 1 (IGF1) signaling pathway expression was increased. With UCS exposure in the PCE offspring, serum corticosterone levels and adrenal steroid synthetase expression were increased, the activity of GC-activation system was enhanced, and adrenal IGF1 signaling pathway expression was decreased. Based on these findings, PCE induced adrenal hypersensitivity in adult male offspring rats, as shown by the reduced corticosterone levels under HFD conditions but significantly enhanced corticosterone levels with UCS, in which GC-IGF1 axis programming alteration may play an important role.

RESUMO

The analysis of dietary patterns has recently drawn considerable attention as a method of investigating the association between the overall whole diet and the risk of colorectal cancer. However, the results have yielded conflicting findings. Here, we carried out a meta-analysis to identify the association between dietary patterns and the risk of colorectal cancer. A total of 40 studies fulfilled the inclusion criteria and were included in this meta-analysis. The highest category of 'healthy' dietary pattern compared with the lowest category was apparently associated with a decreased risk for colorectal cancer [odds ratio (OR)=0.75; confidence interval (CI): 0.68-0.83; P<0.00001]. An increased risk of colorectal cancer was shown for the highest compared with the lowest category of a 'western-style' dietary pattern (OR=1.40; CI: 1.26-1.56; P<0.00001). There was an increased risk of colorectal cancer in the highest compared with the lowest category of 'alcohol-consumption' pattern (OR=1.44; CI: 1.13-1.82; P=0.003). The results of this meta-analysis indicate that a 'healthy' dietary pattern may decrease the risk of colorectal cancer, whereas 'western-style' and 'alcohol-consumption' patterns may increase the risk of colorectal cancer.

RESUMO

Previous studies have attempted to assess the relation between different dietary patterns and the risk of endometrial cancer (EC); however, a consistent perspective has not been established to date. Therefore, we carried out this meta-analysis to evaluate the associations between dietary patterns and the risk of EC. The most common dietary patterns with high loadings of foods and/or nutrients were selected. A total of 27 studies fulfilled the inclusion criteria and were included in the present meta-analysis. There was evidence of a decreased risk of EC in the highest compared with the lowest categories of healthy dietary pattern [odds ratio (OR)=0.74; confidence interval (CI): 0.62-0.88; P=0.008]. An increased risk of EC was shown for the highest compared with the lowest category of a western-style dietary pattern (OR=1.37; CI: 1.15-1.64; P=0.0005). No significant association with the risk of EC was found in the highest compared with the lowest category of alcohol-drinking pattern (OR=0.98; CI: 0.73-1.30; P=0.87). The results of this meta-analysis indicate that some dietary patterns may be associated with the risk of EC.

RESUMO

UNLABELLED: Epidemiological studies of different dietary patterns and the risk of hypertension among a middle-aged Chinese population remain extremely scare. Thus, the aim of this study was to identify dietary patterns and investigate the relationship between dietary patterns and the risk of hypertension among Chinese adults aged 45-60 years. The present cross-sectional study includes 2560 participants who reported their dietary intake using a validated food frequency questionnaire (FFQ). Dietary patterns were identified using factor analysis. Anthropometric measurements were obtained using standardized procedures. We used log-binomial regression analysis to examine the associations between dietary patterns and hypertension risk. Four major dietary patterns were identified and labeled as traditional Chinese, animal food, western fast-food, and high-salt patterns. After adjusting for potential confounders, participants in the highest quartile of animal food pattern scores had a greater prevalence ratio (PR) for hypertension (PR = 1.26; 95% confidence interval (CI): 1.064-1.727; p < 0.05) in comparison to those from the lowest quartile. Compared with the lowest quartile of high-salt pattern, the highest quartile had a higher prevalence ratio for hypertension (PR = 1.12; 95% CI: 1.013-1.635; p < 0.05). CONCLUSIONS: Our findings indicated that animal food and high-salt patterns were associated with increased risk of hypertension, while traditional Chinese and western fast-food patterns were not associated with the risk of hypertension. Further prospective studies are warranted to confirm these findings.

RESUMO

Investigation of the relationship between dietary patterns and some chronic noncommunicable diseases has become appealing in nutritional epidemiology. Some studies have reported potential associations between dietary patterns and the risk of chronic obstructive pulmonary disease; however, the results remain conflicting. Thus, we conducted this meta-analysis to pool the results of studies to clarify the associations between dietary patterns and the risk of chronic obstructive pulmonary disease. A literature search of MEDLINE and EBSCO databases was performed to identify relevant studies published from January 1990 up to June 2015. A total of 13 studies met the inclusion criteria and were included in this meta-analysis. The highest category of healthy/prudent dietary patterns when compared with the lowest category was apparently associated with a decreased risk (OR = 0.55; CI: 0.46, 0.66; P < 0.0001). An increase in the risk of chronic obstructive pulmonary disease was shown for the highest compared with the lowest categories of "unhealthy/western-style" dietary patterns (OR = 2.12; CI: 1.64, 2.74; P < (0.0001). The results of this meta-analysis indicate that different dietary pattern may be associated with the risk of chronic obstructive pulmonary disease.

RESUMO

UNLABELLED: No previous study has investigated dietary pattern in association with obesity risk in a middle-aged Chinese population. The purpose of this study was to evaluate the associations between dietary patterns and the risk of obesity in the city of Hangzhou, the capital of Zhejiang Province, east China. In this cross-sectional study of 2560 subjects aged 45-60 years, dietary intakes were evaluated using a semi-quantitative food frequency questionnaire (FFQ). All anthropometric measurements were obtained using standardized procedures. The partial correlation analysis was performed to assess the associations between dietary patterns and body mass index (BMI), waist circumference (WC), and waist to hip ratio (WHR). Multivariate logistic regression analysis was used to examine the associations between dietary patterns and obesity, with adjustment for potential confounders. Four major dietary patterns were extracted by means of factor analysis: animal food, traditional Chinese, western fast-food, and high-salt patterns. The animal food pattern was positively associated with BMI (r = 0.082, 0.144, respectively, p < 0.05) and WC (r = 0.102, 0.132, respectively, p < 0.01), and the traditional Chinese pattern was inversely associated with BMI (r = -0.047, -0.116, respectively, p < 0.05) and WC (r = -0.067, -0.113, respectively, p < 0.05) in both genders. After controlling for potential confounders, subjects in the highest quartile of animal food pattern scores had a greater odds ratio for abdominal obesity (odds ratio (OR) = 1.67; 95% confidence interval (CI): 1.188-2.340; p < 0.01), in comparison to those from the lowest quartile. Compared with the lowest quartile of the traditional Chinese pattern, the highest quartile had a lower odds ratio for abdominal obesity (OR = 0.63; 95% CI: 0.441-0.901, p < 0.05). CONCLUSIONS: Our findings indicated that the animal food pattern was associated with a higher risk of abdominal obesity, while the traditional Chinese pattern was associated with a lower risk of abdominal obesity. Further prospective studies are warranted to confirm these findings.

RESUMO

Previous studies reported the potential associations between dietary patterns and the risk of coronary heart disease (CHD) in adulthood, however a consistent perspective has not been established to date. Herein, we carried out this meta-analysis to evaluate the associations between dietary patterns and the risk of CHD. MEDLINE and EBSCO were searched for relevant articles published up to April 2015. A total of 35 articles (reporting 37 original studies) met the inclusion criteria and were included in the present meta-analysis. The decreased risk of CHD was shown for the highest compared with the lowest categories of healthy/prudent dietary patterns (odds ratio (OR) = 0.67; 95% confidence interval (CI): 0.60, 0.75; p < 0.00001) and alcohol consumption (OR = 0.68; 95% CI: 0.59, 0.78; p < 0.00001). There was evidence of an increased risk of CHD in the highest compared with the lowest categories of the unhealthy/Western-type dietary patterns (OR = 1.45; 95% CI: 1.05, 2.01; p = 0.02). The results of this meta-analysis indicate that different dietary patterns may be associated with the risk of CHD.
