To study the mechanism of polysaccharides from seeds of Vaccaria segetalis( PSV) in the treatment of bacterial cystitis through the NLRP3 inflammasome pathway. The rat model of urinary tract infection was used and treated with PSV,and the urine and bladders were collected. The level of interleukin-10( IL-10) in rat urine was detected by enzyme linked immunosorbent assay( ELISA). Western blot and immunofluorescence staining were used to detect the expressions of sonic hedgehog( SHH) and NLRP3 inflammasome [NOD-like receptor thermoprotein domain 3( NLRP3),apoptosis associated speck like protein( ASC) and pro-caspase-1]. The expression of Toll-like receptor pathway was detected by RT-PCR. The death of 5637 cells induced by uropathogenic Escherichia coli( UPEC) and lactate dehydrogenase( LDH) release were evaluated using live/dead staining. The results showed that in the rat bladder,the expressions of SHH,NLRP3 inflammasomes and Toll-like receptors were significantly up-regulated,and NLRP3 inflammasomes were significantly activated by UPEC infection. The administration with PSV could significantly increase the concentration of IL-10 in urine,inhibit the expressions of SHH,NLRP3 inflammasomes and Toll-like receptors in bladder,and inhibit the activation of NLRP3 inflammasomes. A large number of 5637 cells were dead after UPEC infection and caused LDH production. PSV could significantly inhibit the death of 5637 cells and the release of LDH. In conclusion,PSV could inhibit the expression and activation of NLRP3 inflammasomes by inhibiting the Toll-like receptor pathway,thereby mitigating the bladder injury.

Long Non-coding RNA CCAT1 Sponges miR-454 to Promote Chemoresistance of Ovarian Cancer Cells to Cisplatin by Regulation of Surviving / Journal of the Korean Cancer Association, 대한암학회지

Purpose@#Colon cancer-associated transcript 1 (CCAT1) was identified as an oncogenic long non-coding RNA (lncRNA) in a variety of cancers. However, there was a lack of understanding of the mechanism by which CCAT1 conferred cisplatin (also known as DDP) resistance in ovarian cancer cells. @*Materials and Methods@#Cell viability of A2780, SKOV3, A2780/DDP, and SKOV3/DDP cells upon cisplatin treatment was monitored by MTT assay. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) detected the expression levels of CCAT1 and miR-454. The effect of sh-CCAT1 on cisplatin response was investigated in xenografts study. Bioinformatic analysis, luciferase reporter assay and qRT-PCR were conducted to validate the direct interaction among CCAT1, miR-454, and survivin. Apoptosis was determined by flow cytometry after dual staining of Annexin-V-FITC/propidium iodide, and the expression of apoptosis-related proteins Bcl-2, Bax and survivin were detected by qRT-PCR and Western blotting. Xenograft study was conducted to monitor in vivo tumor formation. @*Results@#CCAT1 was highly expressed in cisplatin-resistant ovarian cancer cell line A2780/DDP and SKOV3/DDP. Knockdown of CCAT1 restored sensitivity to cisplatin in vitro and in vivo. Our data revealed that silencing of CCAT1 promoted cisplatin-induced apoptosis via modulating the expression of pro- or anti-apoptotic proteins Bax, Bcl-2, and survivin. CCAT1 directly interacted with miR-454, and miR-454 overexpression potentiated cisplatin-induced apoptosis. Survivin was identified as a functional target of miR-454, restoration of survivin attenuated the effect of miR-454 on cisplatin response. In addition, miR-454 inhibitor or overexpression of survivin was found to abolish sh-CCAT1–induced apoptosis upon cisplatin treatment. @*Conclusion@#CCAT1/miR-454/survivin axis conferred cisplatin resistance in ovarian cancer cells.

Animal Models of EV71 and CA16 Hand-foot-mouth Disease and Characteristics of Viral Infection / 中国实验方剂学杂志

Hand-foot-mouth disease (HFMD) is a common infectious disease caused by enterovirus in children. It has a high incidence and can cause fatal complications such as pulmonary edema, myocarditis and aseptic meningitis, seriously threatening the health of children. At present, some core problems such as the pathogenesis of disease, the relationship between different genotypes of pathogenic viruses, the pharmacodynamic evaluation methods, and the antiviral mechanism of drugs are still unclear. The construction of disease animal models with simulation performance of human exposure is the key to solve the above problems. Researchers both at home and abroad have established a variety of animal models for HFMD, of which enterovirus 71 (EV71) and coxsackievirus A16 (CA16) are most common and most widely used. Both EV71 and CA16 are enterovirus A in picornavirus family, so they have similarities in terms of pathogenicity, infection and replication characteristics, clinical symptoms caused by infection and immune response, but also have significant differences in age of susceptibility, method of infection, as well as neurotoxicity, clinical symptoms and signs, and degree of tissue and organ damage. Therefore, researchers shall select and establish proper animal models based on actual conditions, which is critical to the reliability of the results. In this paper, the different types of HFMD animal models established by EV71 and CA16 viruses were reviewed, especially on the species strains, virus strain types, infection methods, and characteristics of viral infections in each model, and the characteristics and clinical symptoms of HFMD induced by EV71 and CA16 were also investigated to provide reference for related research.

Prevalence and influencing factors of carotid plaque in population at high-risk for cardiovascular disease in Jiangsu province / 中华流行病学杂志

Objective@#To understand the prevalence of carotid plaque (CP) in population at high-risk for cardiovascular disease (CVD) in Jiangsu province and identify related influencing factors.@*Methods@#Based on the China Patient-centered Evaluative Assessment of Cardiac Events Million Persons Project from 2015 to 2016, a total of 11 392 persons at high-risk for CVD were selected from six project areas in Jiangsu province for the questionnaire survey, physical measurement, laboratory test and bilateral ultrasound examination of carotid arteries. The prevalence of CP and influencing factors of abnormal carotid arteries, CP and plaque burden (CP≥2) were analyzed.@*Results@#Among the persons surveyed, 4 821 (42.3%) were males. The age of the persons surveyed was (59.4±8.9) years. There were 5 971 abnormal carotid arteries cases (52.4%), including 1 782 carotid intima-media thickness thickening cases (15.6%), 3 811 CP cases (33.5%) and 378 carotid stenosis cases (3.3%). Older age (OR=2.253, 95%CI: 2.127-2.386), urban residence (OR=2.622, 95%CI: 2.375-2.895), hypertension (OR=1.439, 95%CI: 1.195-1.732), smoking (OR=1.441, 95%CI: 1.259- 1.650), pulse pressure difference (OR=1.270, 95%CI: 1.198-1.347), fasting plasma glucose (FPG) (OR=1.109, 95%CI: 1.059-1.161) and LDL-C/HDL-C (OR=1.225, 95%CI: 1.164-1.288) were possible risk factors of CP in population at high risk for CVD. Being women (OR=0.558, 95%CI: 0.494-0.630), high BMI (OR=0.948, 95%CI: 0.904-0.994), higher levels of education (OR=0.708, 95%CI: 0.531-0.945), and higher annual household income (OR=0.773, 95%CI: 0.669-0.894) were the possible protective factors.@*Conclusions@#Over half of the population at high-risk for CVD in Jiangsu showed abnormal carotid arteries. High blood pressure, high blood glucose, high blood lipids and smoking were the main factors that could be changed.

Different level of fasting blood glucose and cardiovascular risk factors clustering among population of Jiangsu Province / 中华疾病控制杂志

Objective To analyze the clustering of major cardiovascular risk factors among population with different level of fasting blood glucose (FBG) in Jiangsu provincial communities. Methods A population-based screening project was conducted during 2015-2017, with 83 522 residents aged 35-75 years from 6 areas included in the study. Prevalence and the clustering of four cardiovascular risk factors (hypertension, obesity, dyslipidemia and smoking) were analyzed. Binary Logistic regression analysis was performed to explore the relationship between FBG and cardiovascular risk factor clustering. Results The prevalence of diabetes was 18.9% among adults aged 35-75 years in Jiangsu province, and 41.4% of them were aware of their disease. Among undiagnosed population, the odd ratios (OR) of cardiovascular risk factors clustering in impaired fasting glucose (IFG) and hyperglycemia group was 1.29 (OR=1.29，95% CI:1.24-1.36，P<0.001) and 1.99 (OR=1.99，95% CI:1.89-2.08，P<0.001), compared with normal FBG group. The control rate of FBG was 15.5% among diagnosed cases. There was no difference in the risk clustering between diabetes patient with and without control of FBG. Conclusions Hyperglycemia and IFG increase the risk of cardiovascular risk factor clustering. Comprehensive interventions should be served as an important role to keep blood glucose at a normal level in high-risk population.

Association between the single nucleotide polymorphism at locus 1165 of β1-adrenoceptor and infection by Enterovirus A71 / 中华实验和临床病毒学杂志

Objective@#To detect the single nucleotide polymorphism (SNP) at locus 1 165 of β1-adrenoceptor (β1-AR) and to investigate the association between the SNP and the infection by enterovirus A71(EV-A71).@*Methods@#Polymerase chain reaction (PCR) amplification technique was used to detect the SNP at locus 1 165 of β1-AR between hand, foot and mouth disease (HFMD) and healthy controls by sanger sequencing method .@*Results@#There was a G1165C SNP and three kinds of genotypes (GG, GC, CC) in β1-AR gene in the 77 cases of EV-A71 HFMD patients and 66 cases of healthy controls. For HFMD patients, frequencies of GG, GC and CC genotypes of the G1165C locus were 10%, 47% and 43%, respectively, and alleles frequency of G and C were 34% and 66%, respectively. But in healthy children, GG, GC, CC genotype frequencies were 7%, 41% and 52%, respectively, and G and C allele frequencies were 28% and 72% respectively. Chi-square analysis showed that there were no significant differences in distribution of genotypes (χ2=1.154, df=2, P=0.562) and alleles frequency (χ2=1.091, df=2, P=0.296) between the EV-A71-infected group and the healthy control group. Between mild and severe EV-A71-infected group, there were no significant differences in distribution of genotypes (χ2=3.945, df=2, P=0.139) and alleles frequency (χ2=3.763, df=2, P=0.052).@*Conclusions@#The 1 165 SNP in the coding region of β1-AR was not associated with EV-A71 infection and its severity.
