Journal of Chongqing Medical University 1986;0(02):-
Objective:To investigate the role of NF-kB activation in the development of multiple organ dysfunction (MOD) during acute obstructive cholangitis (AOC) in rats.Methods:42 Wistar rats were divided into three groups:the AOC group,the group of bile duct ligation (BDL group),and the sham operation group (SO group).All the animals were killed at 6th h or 48th h after operation.Morphological changes in vital organs were observed under light and electron microscope.NF-?B activation was determined with Electrophoretic Mobility Shift Assay (EMSA).Arterial blood gas analysis was performed.Other parameters included the serum levels of lactate dehydrogenase (LDH),alanine aminotransferase (ALT),blood urea nitrogen (BUN),creatinine (Cr) and the plasma levels of TNF-? and IL-6.Results: The significant changesinhistology and ultrastructure of vitalorgans were observedin AOC group .By contrast ,inBDLgroup ,allthefeaturesoforgandamageweregreatlyreduced .NF -?Bactivationinvarioustissues markedlyin creased in AOC group when comparedwith other two groups.Inaddition ,there sults of bloodgasanalysis were obviously abnormalin AOC group ,and there was asignificant difference between AOC an do the rgroups (P

Objective To detect and analyze nuclear factor kappa B (NF-κB),Helicobacter pylori (HP),Helicobacter pylori cytotoxin associated protein A (CagA),platelet (PLT) and platelet associated IgG (PA IgG) in 224 patients with idiopathic thrombocytopenic purpur(ITP) from three urban hospitals of Shaoxing,in order to explore the role of NF-κB and CagA in the pathogenesis of ITP,then to improve the prognosis of ITP.Methods SABC method was used to detect the NF-κB,13C breath test for the determination of the Hp infection.CagA and PA-IgG were tested by enzyme linked immunosorbent assay.Automatic blood cell analyzer was used to measure PLT.According to the test results,the patients were divided into Hp+cagA+NF-κB+,Hp+cagA+NF-κB-,Hp+cagA-NF-κB+,Hp+cagA-NF-κB-,Hp-NF-κB+,Hp-NF-κB-PLT groups,and PA-IgG,PLT of the six groups were statistically analyzed.Results Of 224 cases with ITP,175 cases of HP positive,the positive rate was 78.13%.CagA+ 91 cases in 175 cases of Hp+,accounting for 52%,overall 43.63%.NF-kappa B+ 108 cases,the positive rate was 46.21%,78 cases were found in Hp+cagA+,accounting for 85.71% in cagA+.In 84 cases of Hp+cagA-,there were 21 cases NF-κB+,the positive rate was 25%.In 49 of HP-,9 cases with NF-kappa B+,accounting for 18.37%.PLT and PA-IgG were compared among the groups.The count of PLT of group Hp+,group Hp+cagA+ and group NF-κB+ was lower than group Hp-,group Hp+cagA- and group NF-κB-.However,the level of PA-IgG of group Hp+,group Hp+cagA+ and group NF-κB+ was higher than group Hp-,group Hp+cagA- and group NF-κB-,the difference was statistically significant(P<0.05).Conclusion CagA maybe directly or through the activation of NF-kappa B take part in the immune response of ITP,cause PA-IgG increased and thrombocytopenia.

Objective To study the effects of apoptosis of the tumor cells in rabbit liver VX2 carcinoma after treatment by radiofrequency ablation(RFA) combined with trans arterial chemoembolization(TACE) and high‐frequency hyperthermia(HFH) . Methods Rabbit liver VX2 carcinoma model was established .Rabbit liver VX2 tumor models were divided into the following group:group A ,RFA+ TACE;group B ,RFA + TACE + HFH ;group C ,RFA + HFH ;group D ,TACE+ HFH .The changes of serum ALT was detected to realize the safety of the treatment .Cell apoptosis were detected by DNA agarose gel electrophoresis and terminal deoxynucleotidyltransferase‐mediated Dutp nick end‐labeling(TUNEL) assay ;SP immunohistochemistry ,Western blot and Real‐time quantitative PCR(RT‐PCR) were used to detect Caspase‐3 protein and mRNA expression levels .Results The changes of serum ALT in group B was significantly higher .Compared with other groups ,the apoptosis index in group B was increased marked‐ly(P<0 .05) .Western blot and RT‐PCR Caspase‐3 protein and mRNA levels in group B were higher than the other groups(P<0 .05) .Conclusion RFA+ TACE+ HFH can effectively kill tumor cells and promote apoptosis of tumor cells ,but ,at the same time ,can damage liver function .

To explore screening tools for children with autism spectrum disorder (ASD), which are convenient for primary hospitals, it can provide basic data for formulating ASD prevention policies. This was a cross-sectional study by cluster sampling. Huyi District and Xincheng District were extracted for investigation in Xi'an City. From July 2021 to September 2022, all children aged from 3 months to 36 months who live in the two districts were subjected to primary screening. The child care physician used the routine screening tool "warning signs checklist for screening psychological, behavioral and developmental problems of children" and cartoon pictures of "early high-risk warning signs of autism", the children who were positive in the initial screening were referred to the district level maternal and child health hospital for re-screening, and those who were positive in the re-screening were referred to Xi 'an Children's Hospital for diagnosis. The results showed that a total of 17 905 children aged from 3 months to 36 months were initially screened in the two districts, including 10 588 children aged from 18 months to 36 months, 50 children who were positive in the initial screening and 50 children who were re-screened. 23 children (18 boys and 5 girls) were diagnosed with ASD. The prevalence rate of ASD in children was 2.17‰ (95% confidence interval:1.29‰-3.06‰). 42 children were positive for "warning signs checklist" at the preliminary screening, and 19 were confirmed as ASD. 27 children were positive for "cartoon pictures" in the preliminary screening, and 23 were confirmed with ASD. The "cartoon pictures" in the preliminary screening and diagnosis of consistent rate was higher than the "warning signs checklist", two kinds of screening methods comparison were statistically significant difference in the odds of consistent (χ2=11.01, P=0.001). In conclusion, relying on the three-level network of maternal and child health care, it is conducive to the whole process management of screening and diagnosis of children with ASD, and to guide the formulation of prevention policies. The cartoon pictures of "early high-risk warning signs of autism" can assist the identification of children with ASD based on the "warning signs checklist", which is simple, effective and suitable for promotion in the community health care.

Aging-induced changes in the immune system are associated with a higher incidence of infection and vaccination failure. Lymph nodes, which filter the lymph to identify and fight infections, play a central role in this process. However, careful characterization of the impact of aging on lymph nodes and associated autoimmune diseases is lacking. We combined single-cell RNA sequencing (scRNA-seq) with flow cytometry to delineate the immune cell atlas of cervical draining lymph nodes (CDLNs) of both young and old mice with or without experimental autoimmune uveitis (EAU). We found extensive and complicated changes in the cellular constituents of CDLNs during aging. When confronted with autoimmune challenges, old mice developed milder EAU compared to young mice. Within this EAU process, we highlighted that the pathogenicity of T helper 17 cells (Th17) was dampened, as shown by reduced GM-CSF secretion in old mice. The mitigated secretion of GM-CSF contributed to alleviation of IL-23 secretion by antigen-presenting cells (APCs) and may, in turn, weaken APCs' effects on facilitating the pathogenicity of Th17 cells. Meanwhile, our study further unveiled that aging downregulated GM-CSF secretion through reducing both the transcript and protein levels of IL-23R in Th17 cells from CDLNs. Overall, aging altered immune cell responses, especially through toning down Th17 cells, counteracting EAU challenge in old mice.
