1.Progress of T helper cell 17,regulatory T cell,podocyte injury and primary glomerular disease
International Journal of Pediatrics 2016;43(1):66-69,70
In recent years,T helper cell 17(Th17),regulatory T cell(Treg) and podocyte injury attrac-ted widespread attention in the pathogenesis of primary glomerular disease. Th17 cells have the function of re-cruiting neutrophils and macrophages to the infected tissue through the secretion of cytokines such as IL-17. Treg cells have immune function, mediated immune tolerance, protecting the body against inflammatory injury. The imbalance of Th17 cells increase and Treg cells decrease could play an important role in the pathogenesis and progression of primary glomerular disease. As the important part of the glomerular filtration barrier,podocyte be-comes the focus in recent years. Study on relationship among Th17,Treg,podocyte injury and primary glomeru-lar disease will provide more theoretical basis for the prevention and treatment of primary glomerular disease.

Objective To explore the case management model of return to work injured workers. Methods A retrospective cohort wasformed with 523 injured workers in rehabilitation centre. The social demographic information, medical data and intervention process wereextracted from the medical records. A Cox Regression Model was used to examine the effect of case management on work processes and otherrelevant factors affecting RTW. Results 275 cases (82.1%) out of the 335 subjects successfully returned to work after median absence durationof 36.0 days. Computer training prompted RTW outcomes (P<0.01), while disability adjustment activity showed an opposite effect(P<0.05). It showed that education level, family attitude to RTW and level of injury were significantly associated with outcomes of RTW.Conclusion Specific skills reconstruction and training would is one of the most important components of the case management interventionprogram on RTW. Although disability adjustment did not specifically benefit RTW, it might help in improving workers' general health status,and it should not be ignored in any case.

Objective To investigate the various occasions of invasive mechanical ventilation in patients with acute left heart failure. Methods Thirty-two patients with acute severe left heart failure were divided into two groups:17 patients were treated with non-invasive mechanical ventilation (non-invasive mechanical ventilation group) and 15 patients were treated with invasive mechanical ventilation (invasive mechanical ventilation group). The respiratory rate (RR), arterial oxy-gen partial pressure p(O2), heart rate (HR) and mean arterial pressure (MAP) were observed after treatment for 0.5 h,1 h and 3 h in two groups of patients. The in-hospital mortality was compared between two groups. Results Ten patients of non-in-vasive mechanical ventilation group were in remission after 0.5 h, 7 cases without remission switched to endotracheal intuba-tion for invasive mechanical. And 3 of them were in remission in 0.5~1 h, 4 of them dead. Fourteen patients in invasive me-chanical ventilation group were in remission after 0.5 h, one case was in remission after 0.5~1 h and no dead in this group. There were more patients in remission after 0.5 h in invasive mechanical ventilation group than those of non-invasive me-chanical ventilation group (P=0.041). There were no significant differences in the number of patients in clinical remission af-ter 0.5~1 h and mortality between two groups. The values of RR and HR were decreased with the increasing treatment time in two groups. The values of p(O2) and MAP were increased with the increasing treatment time in two groups. There was a sig-nificantly lower RR at 0.5 h and 1 h in invasive mechanical ventilation group than that of non-invasive mechanical ventila-tion group (P < 0.05). The values of p(O2) and MAP were significantly higher at 0.5 h in invasive mechanical ventilation group than those of non-invasive mechanical ventilation group (P<0.05). The levels of HR at 0.5 h and 3 h were significant-ly lower in invasive mechanical ventilation group than those of non-invasive mechanical ventilation group ( P<0.05). Con-clusion Invasive mechanical ventilation should be used as soon as possible if non-invasive mechanical ventilation can not alleviate the symptoms in patients more than 0.5 hours.

Aim To evaluate the mucosal-protective effects of carboxymethylpachyman( CMP) on Fluorou-racil(5-Fu)-induced mice intestinal mucositis and ex-plore its mechanisms. Methods ICR mice were as-signed randomly to four groups:normal group( n=8;re-ceiving pure water orally for 14 d) ,CMP group( n=8;200 mg·kg-1 CMP for 14 d orally),5-Fu group(n=8;25 mg·kg-1 5-Fu for 7 d,intraperitoneally( i. p. ) , and CMP+5-Fu group( n=8;200 mg·kg-1 CMP for 14 d orally and 25 mg·kg-1 5-Fu for 7 d,i. p. ). At day 14the mice were sacrificed. The intestinal propel-ling rate and the colon length were measured. ROS, GSH and IL-1βcontents,and CAT,GSH-Px activities in homogenate supernatant of PPs were measured by kits for observing the effects of CMP on mice lipid peroxida-tion and intestinal mucosal inflammatory induced by 5-Fu. Colon tissues were used for hematoxylin and eosin ( HE ) staining for the determination of the effect of CMP on mice colon histopathology, immunohistochem-istry for the protein levels of NF-κB and p-p38 . Results CMP significantly extended colon lengths,accelerate the intestinal propelling rates, reduced colonic mucosa epithelium goblet cell loss, inflammatory cells infiltra-tion,and crypt depth shallow induced by 5-Fu. CMP obviously reduced ROS and IL-1β contents, and pre-vented reductions in homogenate supernatant of PPs GSH content, CATand GSH-Px activities by 5-Fu ad-ministration,and also reduced the expression of NF-κB and p-p38 in colon tissues. However, CMP alone had no effect on the colon of normal mice. Conclusion The current study demonstrates that CMP may have sig-nificant protective effects against 5-Fu-induced intesti-nal mucositis. Its mechanism may be related to enhan-cing the antioxidant activity,anti-inflammatory and an-ti-apoptotic effects.

Objective:
To understand health literacy and associated factors of freshmen from Jiangsu Province, and to provide reference for youth health education.
Methods:
From 2017 October to 2018 October, a total of 15 602 college freshman were randomly selected from 20 universities in Jiangsu Province via stratified cluster sampling method. Structural questionnaires were used to investigate the status of health literacy. The χ 2 test and multivariate Logistic regression model were used to analyze the influencing factors of health literacy.
Results:
The health literacy level of college freshmen from Jiangsu Province was 20.2%, among which the literacy levels of knowledge, behavior and skills were 23.0%, 30.7% and 31.5% respectively. The literacy levels of the six public health issues, including safety and first aid, scientific health attitude, knowledge of prevention and treatment of infectious diseases, health information, basic health care, and prevention and treatment of chronic diseases, from high to low, were 72.8%, 58.7%, 28.5%, 28.2%, 20.3% and 15.9%, respectively. Multivariate Logistic regression analysis has showed that students from undergraduate colleges(OR=2.77, 95%CI=2.47-3.11), urban areas(OR=1.20, 95%CI=1.07-1.34), or southern Jiangsu regions(OR=1.10, 95%CI=1.00-1.22), being the only child(OR=1.13, 95%CI=1.03-1.25), higher maternal education level (OR=1.53, 95%CI=1.30-1.79), having both parents(OR=1.16, 95%CI=1.00-1.34), reported higher level of health literacy.
Conclusion
The three aspects and six dimensions of health literacy of college freshmen were unbalanced. Health literacy is a shared function of multiple factors including society, family, and individuals. It is essential to promote health education through more efforts on key issues, in order to effectively elevate the health literacy level of adolescent students.

OBJECTIVE:
To choose the disease-causing gene in a Chinese pedigree with ankylosing spondylitis (AS) by whole-exome sequencing (WES), and provide theory basis for mechanism of disease.
METHODS:
Clinical data of AS pedigree were collected, including 2 males, the age were 48 and 18 years old, the course of disease were 23 and 4 years. Whole blood genomic DNA of AS was extracted to perform whole exome sequencing, the results were compared with human databases, common variations which had been reported were wiped out, then non synonymous single nucleotide variants(SNVs) from the family members were combined, and candidate genes was selected initially.
RESULTS:
Totally 80 G data was obtained from AS family with high quality.By comparing results between patient and normal subject, and filtering with number of biological database, the result showed heterozygous mutation of JAK2 gene 12 exon c.1709 A>G (p.Tyr570Cys) may be the potential disease-causing gene. The variant c.1151T>C of MUC3A gene may be one of the causes of intestinal symptoms in the family members.
CONCLUSION
It is feasible to find t candidate gene mutations of AS by Exon sequencing. The mutation c.1709 A>G in gene JAK2 identified by whole exome sequencing might be the pathogenic mutation in this AS pedigree.
