ABSTRACT

OBJECTIVE@#To analyze the clinical features of a Chinese pedigree affected with tuberculosis sclerosis and explore its molecular pathogenesis.@*METHODS@#Clinical data of the proband and members of his pedigree were collected. Whole exome sequencing was carried out to detect variants of the TSC1 and TSC2 genes. Candidate variants was verified by Sanger sequencing and bioinformatic analysis.@*RESULTS@#The proband and his mother, who also had mild features of tuberous sclerosis, were found to harbor a novel heterozygous c.4183C>T (p.Q1395X) variant of the TSC2 gene, which was absent in the 4 healthy relatives. Bioinformatic analysis suggested the variant to be likely pathogenic.@*CONCLUSION@#The heterozygous c.4183C>T (p.Q1395X) variant of the TSC2 gene probably underlay the disease in this pedigree. Above finding has expanded the spectrum of TSC2 gene variants. The more severe symptoms in the proband may be attributed to phenotypic heterogeneity of this disease.

ABSTRACT

Objective:To analyze the relationship between red cell distribution width (RDW) and disease severity in patients with non-ST-elevation myocardial infarction.Methods:Seventy patients with non-ST-elevation myocardial infarction who received treatment in Chaozhou People's Hospital from June 2019 to June 2020 were included in the observation group. An additional 70 patients with ST-elevation myocardial infarction who concurrently received treatment in the same hospital were included in the control group. All patients underwent electrocardiography and blood biochemical index examination. RDW was compared between the observation and control groups. The relationship between RDW and the severity of non-ST-elevation myocardial infarction was analyzed.Results:RDW in the observation group was significantly higher than that in the control group [(14.60 ± 1.00) % vs. (13.06 ± 1.70) %, t = 5.884, P = 0.012). The detection rate of coronary artery thrombosis in the observation group was significantly higher than that in the control group [70.00% (49/70) vs. 50.00% (35/70), χ2 = 7.563, P = 0.002]. In the observation group, the area under the receiver operating characteristic (ROC) curve plotted taking RDW as the variable was 0.649 (95% CI 0.546-0.753, P = 0.006). When the critical value of RDW was 14%, the sensitivity and specificity of RDW in the prediction of non-ST-elevation myocardial infarction were 73% and 59% respectively. RDW was positively correlated with cardiac troponin I level ( r = 0.19, P = 0.006). Conclusion:In patients with non-ST-elevation myocardial infarction, the increase in RDW is related to myocardial injury and the increase in cardiac troponin I level. RDW can be used as an effective index to predict the severity of non-ST-elevation myocardial infarction.

ABSTRACT

Chondroitin sulfate (CS) is a sulfurated glycosaminoglycan, a major component of the extracellular matrix, widely distributed in skin, cartilage and vascular tissue. CS plays an important role in the physiological state regulation of articular cartilage, which affects tensile strength and elasticity of tissues by influencing aggrecan. Previous studies have shown that CS sulfate modification may be related to the growth and development disorders of cartilage tissue and the occurrence of osteoarticular diseases. At the same time, CS is also a common joint supplement, often used in the treatment of osteoarthritis and Kashin-Beck disease. In this paper, the research progress of CS sulfate modification characteristics in Kashin-Beck disease and osteoarthritis and the application of the preparation in the treatment of Kashin-Beck disease and osteoarthritis are reviewed, aiming to provide help for the investigation of the etiology of Kashin-Beck disease and the treatment of osteoarthritis and Kashin-Beck disease.

ABSTRACT

In eukaryote cells,transcription from genome DNA is a key process of gene expression.The transcription products contain not only messenger RNAs that code proteins,but also various types of non-coding RNAs.During transcription,some of the gene loci produce more than one kind of RNA molecule,including coding RNAs and more often non-coding RNAs.These gene loci that generate several kinds of RNA molecules are named supergenes.According to the transcription pattern,supergenes are divided into three types,known as types Ⅰ,Ⅱ and Ⅲ.In this review,we summarize the transcription pattern of each type of supergene,and exposit the role of these genes in cells.

ABSTRACT

Objective:To investigate the targets and possible mechanism of Didangtang in the treatment of bladder cancer. Method:Based on multiple traditional Chinese medicine and disease databases, the network pharmacology was used to screen potential targets, analyze the biological functions of potential targets, and construct a network of "Chinese medicine-target-path-disease". Bioinformatics analysis was applied in population and gene databases, in order to explore the differential expressions of core targets in tissues, distribution in the population and the correlation with prognosis. The in vitro experiment was used to verify the biological function of Didangtang. The underlying mechanism of Didangtang on the candidate target was detected. Result:A total of 21 core target genes and 16 highly enriched pathways were screened out. A functional network of Didangtang was constructed systematically. At the same time, six targets, namely cadherin 1 (CDH1), CAMP responsive element binding protein 1 (CREB1), colony stimulating factor 2 (CSF2), AP-1 transcription factor (JUN), matrix metalloproteinase 2 (MMP2), and prostaglandin-endoperoxide synthase (PTGS2), were differentially expressed in bladder cancer tissues (P<0.05). Furthermore, JUN and MMP2 were also differentially distributed in population (P<0.05). At the same time, the expression level of JUN was correlated with the prognosis of patients with bladder cancer (P<0.05). The in vitro experiment revealed that Didangtang inhibited the proliferation of bladder cancer cells and decreased the expression of candidate target JUN (P<0.01). Conclusion:Didangtang has the characteristics of multiple targets and multiple pathways in treatment of bladder cancer. It is initially confirmed that Didangtang can affect the expression of target JUN and inhibit the proliferation of bladder cancer, which lays a good foundation for further studies on mechanism.

ABSTRACT

Objective:To explore the value of thyroid radioactive iodine uptake (RAIU) on predicting the residual activity in patients with differentiated thyroid carcinoma (DTC) after administration of 131I. Methods:A total of 178 patients (63 males, 115 females, age: (39.8±11.4) years) with DTC who underwent initial treatment of 131I in Suzhou Science & Technology Town Hospital between August 2018 and April 2019 were enrolled in this retrospective study. RAIU test and thyroid imaging were performed before 131I treatment. Patients were divided into 3 groups according to the thyroid remnant showed by thyroid imaging: no remnant group, a little remnant group, and obvious remnant group. Radiation dose equivalent rates at different time points (immediately/24 h/48 h/72 h after injection of 131I) were measured to estimate the residual activity of 131I after administration. RAIU and residual activity at 72 h among different thyroid remnant groups were compared by one-way analysis of variance. Relationship between RAIU/ 131I therapeutic dose and residual activity at 72 h was analyzed by Pearson correlation analysis. The linear regression equation between RAIU and residual activity at 72 h after treatment was established. Results:The 3 h RAIU in no remnant group ( n=45), a little remnant group ( n=101), and obvious remnant group ( n=32) were (4.77±1.46)%, (5.53±1.70)% and (8.92±3.75)%, respectively ( F=39.35, P<0.01), and the 24 h RAIU was also significantly different among those 3 groups ((1.54±0.88)%, (3.41±2.55)%, (13.52±8.59)%; F=91.52, P<0.01). The residual activity at 72 h in no remnant group, a little remnant group, and obvious remnant group were (81.70±25.61), (108.24±51.58) and (283.07±133.72) MBq, respectively ( F=92.84, P<0.01). There was a significant positive correlation between RAIU and the residual activity at 72 h (3 h: r=0.753, 24 h: r=0.817, both P<0.01). The linear regression equations between RAIU at 3 h and 24 h and the residual activity at 72 h were y=28.88 x-38.42 and y=13.87 x+ 67.01, respectively. When RAIU was higher than 24.01% at 3 h or 15.18% at 24 h, the residual activity at 72 h after treatment was likely to exceed 400 MBq. There was little correlation between 131I therapeutic dose and the residual activity at 72 h after treatment ( r=0.119, P>0.05). Conclusion:RAIU can be used to predict the residual activity at 72 h after treatment in DTC patients who underwent initial 131I treatment.

ABSTRACT

Objective:To explore the expression of Aurora Kinase A (AURKA) in hepatocellular carcinoma (HCC) and its prognostic value.Methods:mRNA expression profiles and clinical data of HCC patients were downloaded from the Cancer Genome Atlas (TCGA) database. Expression of AURKA mRNA in HCC patients of TCGA database from normal liver tissue and all tumor tissues, normal tissues adjacent to cancer and matched tumor tissues were analyzed, and then expression of AURKA to was investigated in HCC tissues and normal liver tissues in the Human Protein Atlas (HPA) database. According to the TNM stage information of HCC patients in TCGA database, expression of AURKA in different stages was analyzed. Kaplan-Meier method was used to analyze whether the high and low expression of AURKA in HCC patients of TCGA database (with the median as the cut-off value) was significantly related to the length of survival. The RNA-seq expression profile data of HCC patients in the public resource platform of the Kaplan-Meier Plotter website was used for external verification. Cox univariate and multivariate analysis were performed on the age, sex, degree of differentiation, TNM stage, and AURKA mRNA expression of TCGA database patients.Results:374 cases of HCC tumor tissues and 50 cases of adjacent normal liver tissues in the TCGA database were included. All HCC tumor tissues in the TCGA database compared with the paired adjacent tissues mRNA level of AURKA was significantly increased, and the protein level was also increased, the difference was statistically significant ( P<0.05); With the tumor TNM stage increase of AURKA mRNA expression showed a gradual upward trend, and the difference was statistically significant ( P<0.05); in the TCGA database HCC cohort, high expression of AURKA mRNA was associated with poor HCC prognosis, and was obtained in Kaplan Meier Plotter database. The difference was statistically significant ( P<0.05); Cox multivariate regression analysis showed that TNM stage ( HR=1.69, 95% CI: 1.37-2.10) and AURKA mRNA expression level ( HR=1.03, 95% CI: 1.01-1.10) are the independent prognostic factors of HCC patients. Conclusions:AURKA is highly expressed in HCC, which is associated with the poor prognosis of HCC. AURKA is an independent prognostic factor of HCC.

ABSTRACT

Objective:To analyze the risk factors for severe acute pancreatitis (SAP) complicated with infection and the effects on immune level.Methods:A total of 150 SAP patients admitted to Deyang People′s Hospital from February 2018 to April 2019 were divided into the infected group ( n=90) and the uninfected group ( n=60) according to whether SAP was complicated with infection or not; the changes of pathogenic bacteria in the infection focus, infection risk factors, blood inflammatory cytokines levels and T-lymphocyte subgroups were analyzed. Results:A total of 105 pathogenic bacteria were detected in 90 SAP patients with infection, among which 74(70.5%) were gram-negative bacteria, mainly escherichia coli, klebsiella pneumoniae and pseudomonas aeruginosa. There were 27 strains (25.7%) of gram-positive bacteria, mainly staphylococcus aureus, and 4 strains (3.81%) of fungi. Biliary causes, total parenteral nutrition time≥1 week, APACHEⅡ score≥11, surgical intervention, and respiratory mechanical ventilation were all independent factors for SAP infection (all P<0.05). At 24 hours after onset, blood IL-4(59.1±6.2)ng/L, IL-6(134.1±12.2) ng/L, IL-10(146.4±13.2)ng/L, TNF-ɑ(76.3±5.2)ng/L in infected group were all significantly higher than those in the uninfected group (all P values <0.05); at 30 days after the onset, blood IL-4(33.6±5.8)ng/L, IL-6(49.2±6.8)ng/L of the infected group, IL-10(80.7±8.8)ng/L, TNF-ɑ(28.7±5.5)ng/L in infected group were significantly lower than those in the uninfected group (all P values <0.05). At 24 hours after onset, the proportion of CD 4+ T lymphocytes in the infected group was significantly higher than that in the uninfected group [(45.3±5.5)% vs (32.3±5.2)%], and the proportion of CD 8+ T lymphocytes was significantly lower than that in the uninfected group [(20.6±4.2)% vs (29.7±4.8)%]; at 30 days after onset, the proportion of CD 4+ T lymphocytes in the infected group was significantly lower than that in the uninfected group [(21.6±3.7)% vs (40.2±2.5)%], and the proportion of CD 8+ T lymphocytes was significantly higher in the uninfected group [(48.4±4.1)% vs (32.8±4.0)%]; and all the differences were statistically significant (all P <0.05). Conclusions:The strains of concurrent infection with SAP were mainly gram-negative bacteria. Biliary causes, total parenteral nutrition time, surgical intervention and respiratory mechanical ventilation were all risk factors for concurrent infection with SAP. SAP infection may cause excessive inflammatory response and lead to immune cell damage, which should be paid attention to in clinical treatment.

ABSTRACT

This study aims to investigate the effect of substances secreted or metabolized by vascular endothelial cells on epithelial-mesenchymal transition (EMT) of hepatocellular carcinoma cells under indirect co-culture condition. Human hepatocellular carcinoma cell line QGY-7703 was cultured , and then was co-cultured with conditioned medium of human umbilical vein endothelial cells (HUVEC). The morphological changes of QGY-7703 cells were observed by inverted phase contrast microscopy. The migration ability of QGY-7703 cells was analyzed by scratch-wound assays. The effect of conditioned medium on the expression and distribution of EMT related proteins was detected by Western blot and immunofluorescence assays, respectively. The results showed that the QGY-7703 cells gradually changed from polygonal to spindle shape, the migration ability promoted significantly, and both the expression and distribution of EMT related marker changed in a time-dependent manner after co-culturing. The results confirm that vascular endothelial cells can induce EMT in hepatocellular carcinoma cells under indirect co-culture condition.

ABSTRACT

The article aims to explore the optimal concentration of arsenic trioxide (As O ) on HepG2 of liver cancer cells, and the effect of As O on the migration, invasion and apoptosis of HepG2 cells. In this study, the activity of HepG2 cells treated with 0, 1, 2, 4, 8, 16, 32 μmol/L As O was tested by CCK-8 method, the semi-inhibitory concentration (IC50) was calculated, and the morphological changes of HepG2 cells were observed after the action of As O at IC50 concentration for 12, 24, 48 h. The effect of As O on cell migration and invasion ability was verified by wound healing experiment and Transwell invasion experiment. Western blot and qRT-PCR were used to detect the effects of As O on the gene and protein expression levels related to cell migration, invasion and apoptosis. The results showed that, compared with the control group, the activity of HepG2 cells decreased with the increase of the concentration of As O treatment, showing a dose-dependent effect, and its IC50 was 7.3 μmol/L. After 24 hours' treatment with 8 μmol/L As O , HepG2 cells underwent significant apoptosis, and its migration and invasion abilities were significantly reduced. In addition, the protein expression levels of RhoA, Cdc42, Rac1 and matrix metalloproteinase-9 (MMP-9) were down-regulated, the protein and mRNA expression levels of anti-apoptotic gene Bcl-2 were significantly down-regulated, and the protein and mRNA expression levels of pro-apoptotic genes Bax and Caspase-3 were significantly up-regulated. The above results indicate that certain concentration of As O can inhibit the migration and invasion of hepatocellular carcinoma cells and promote the apoptosis of hepatocellular carcinoma cells.

Objective To evaluate the effect of comprehensive intervention program on hypertension control in workplaces in China.Methods The study design was a non-randomized controlled trial.First,20 sub-centers were selected across China,then hypertension patients in 2-4 workplaces were selected as the intervention group,and hypertension patients in 1 comparable workplace selected,as the control group in each sub-center.The comprehensive intervention strategy which integrating workplace primary prevention of cardiovascular diseases and standardized management of hypertension was adopted in the intervention group for at least 2 years.Patients in the control group continued their usual health care,and only baseline data and 2-year data was collected.Analyses were conducted for hypertension patients in 30 stated-owned enterprises (SOEs),including 20 for the intervention group and 10 for the control group.The primary outcome was the control rate ofhypertension while the intervention effect (IE) was estimated by using the formula:differential value of intervention group [rate (mean)] — differential value of control group [rate (mean)].Results Overall,2 622 patients completed the 2-year follow-up,of which 2 055 were in the intervention group and 567 in the control group,respectively.After 2 years of intervention,the IE on the level of SBP and DBP for intervention group and control group were-7.5 and-3.9 mmHg,respectively (P<0.05).BMI decreased by 0.4 kg/m2,with the regular exercise rate as 36.4% and alcohol consumption rate decreased by 14.0%,respectively (P<0.05).The smoking rate decreased by 6.1% (P>0.05).The overall hypertension control rate was 25.0%,and further subgroup analysis showed that our intervention program was particularly effective for those with high education level (27.6%),white-collar employees (41.9%),and those from SOEs whose affiliated hospital had been separated away (41.9%).Conclusion The comprehensive intervention program could greatly improve the hypertension control in the workplaces in China.

ABSTRACT

Acute promyelocytic leukemia (APL) is a special type of acute leukemia. The cure rate of APL has been significantly improved in the past decades due to the use of anthracyclines, all-trans retinoic acid and arsenic. Modern stratified treatment of APL further enhances the therapeutic efficacy and reduces the treatment-related toxicity. This article reviews the history of all-trans retinoic acid and arsenic into clinical application, and the characteristics of disease, treatment status of all-trans retinoic acid and arsenic, treatment mechanism and drug resistance mechanism in APL are introduced.

ABSTRACT

Objective The objective of this study was to investigate the relationship between the molybdenum target imaging features and clinical signs of mammography,and the expression of HER-2 receptor in breast cancer patients with positive receptors of estrogen and progesterone. Methods One hundred and eleven patients with estrogen and progesterone receptor-positive breast canc-er who were admitted to our hospital from July to September 2017 were examined with mammography before operation. Immunohisto-chemical analysis was performed on breast cancer tissues. Pathological features and features related to mammography were analyzed af-ter operation. The relationship between clinicopathological features and mammography-related signs,and HER-2 expression was al-so analyzed statistically. Results Of the 111 patients,34 were HER-2 positive patients. There were significant difference between the observed indicators and the over-expression of HER-2(P<0. 05). These indicators included lymph node metastasis,calcifica-tion of the mass,margin of the mass,the shape of calcification,and the blood status of vessels. The mammography of patients with tri-ple positive breast cancer is more likely to manifest as lymph node enlargement,mass with calcification or simple calcification,margin-al burrs,granular calcification,and vascular thickening. Conclusion The expression of HER-2 in breast cancer patients with posi-tive estrogen and progesterone receptors can be reflected to some extent by lymph node metastasis,tumor with calcification,tumor mar-gin,calcification,calcification morphology and peripheral blood vessel thickening. In terms of clinical conditions,The biological behav-ior and characteristics of tumor can be inferred based on the clinicopathological features of the patient and the imaging findings of the mammography,providing a direction for the treatment and evaluation of prognosis in breast cancer patients.
