Objective To screen, analyze and predict microRNAs (miRNAs) related to systemic scle-roderma (SSc). Methods Differentially expressed miRNAs between tissue samples from 3 patients with SSc and 3 normal human controls were screened with a gene chip including 924 miRNAs. Target genes regulated by differentially expressed miRNAs were searched with bioinformatics method. Finally, miRNAs related to SSc were predicted. Results There were 24 miRNAs differentially expressed between tissue samples of SSc and normal controls, including 9 up-regulated miRNAs and 15 down-regulated miRNAs. Literature review disclosed that SSc was associated with target genes regulated by hsa-miR-206, has-let-7g, hsa-miR-133a, hsa-miR-125b, hsa-miR-40-5p and hsa-miR-23b. In particular, 15 target genes regulated by hsa-miR-206 were closely correlated with the pathogenesis of SSc. Conclusions In lesions of SSc, there is an expression of miRNAs related to the pathogenesis of SSc, which may include hsa-miR-206 as well as 5 other miRNAs.

Objective To investigate the application of Follow-up System in health management for the patients after percutaneous coronary intervention (PCI). Methods 100 patients underwent PCI were divided into study group (n=50) and control group (n=50). The control group received routine follow-up and the study group was followed up with the direction of Follow-up System. The incidence of adherence to medication after discharge and awareness of risks of coronary heart disease were recorded 6 and 12 months after discharge. Results The incidence of adherence to medication decreased in the control group (P<0.05) after discharge, but was stable in the study group (P>0.05). Awareness of risks of coronary heart disease increased in the study group 12 months after discharge (P<0.01), but was stable in the control group (P>0.05). Conclusion Follow-up System may help to improve the compliance and awareness in health management in the patients after PCI.

Objective To investigate the clinicopathological features, immunophenotyping and clinical biological behavior of bone marrow (BM) involvement of systemic anaplastic large-cell lymphoma (S-ALCL).Methods 34 S-ALCL including 24 ALK(+) and 10 ALK(-) cases available with the formalin-fixed, paraffin embedded (FFPE) tissue blocks of BM biopsy (n=19) or BM smear sections (n=15) were included in this study.BM samples were sent to both morphologic evaluation using H&E (Hematoxylin & Eosin)-stained sections and immunophenotypic detection by immunohistochemistry (IHC). EBV status was determined by visualization of EBERs in tumor cells using in situ hybridization (ISH). Results BM involvement was seen in 17.6 % (6/34)S-ALCL patients which were confirmed by BM biopsy. No significant difference in the incidence of BM involvement was observed between ALK(+)[16.7 % (4/24)] and ALK(-) [20.0 % (2/10) S-ALCL (P =0.3555).Age and gender were not associated with the presence or the absence of BM involvement by S-ALCL (P= 0.8089and 0.3085), tumor cells of patients with BM involvement were interstitial distribution. S-ALCL patients with BM involvement have a poor prognosis as compared to those without BM involvement (P =0.0407). Conclusion BM involvement was not frequently seen in S-ALCL. The occurrence of BM involvement by S-ALCL was not associated with age, gender or the expression of ALK protein. BM involvement is an adverse prognostic factor in S-ALCL, BM biopsy is useful to predict the prognosis of S-ALCL.

Objective:To investigate the pathogenic distribution of benign infantile convulsions with mild gastroenteritis(BICE)and explore the relevance of serum cytokines and BICE.Methods:Eighty BICE infants admitted in Inner Mongolia Maternal and Child Health Hospital from January 2017 to December 2019 were selected as BICE group, and 80 mild gastroenteritis infants without convulsion attack were selected as control group during the same period.Fluorometric real-time PCR was used to detect the pathogen of enterovirus.Serum cytokines including interleukin(IL)-6, tumor necrosis factor(TNF)-α, IL-8 and soluble interleukin-2 receptor(SIL-2R)were detected by using chemiluminescence method.The relevance of frequency and duration of convulsion in infants with BICE and the indicators above were analyzed.Results:Rotavirus infection was the main cause of BICE during the study period in this region.Among 80 cases in the BICE group, rotavirus positive infants accounted for 38.8%(31/80) and norovirus positive infants accounted for 10.0%(8/80). The levels of IL-6, IL-8 and SIL-2R in the BICE group were prominently higher than those in the control group( P<0.05); the difference of TNF-α level between two groups had no statistical significance( P>0.05). The levels of IL-6, TNF -α, IL-8, SIL-2R in the group with convulsion attack times ≥ 2 and convulsion duration ≥5 min were higher than those in the group with convulsion attack times<2 and convulsion duration<5 min( P<0.05). The frequency and duration of convulsions were positively correlated with the levels of IL-6, TNF -α, IL-8 and SIL-2R( P<0.05). Conclusion:Rotavirus is the main pathogen of BICE in this region.There is immunologic imbalance in children with BICE, especially the changes of IL-6 and SIL-2R levels, which may provide effective cytological and experimental data evidence for judging progression and prognosis of the disease.

Objective To investigate the prevalence and risk factors of chronic kidney disease (CKD) in the general adult population in the Hulunbeir Prefecture, Inner Mongolia Autonomous Region where many minorities of north China live. Methods Sampling surveywas performed in the residents aged 20 years and older in the Hulunbeir Prefecture. All the investigated subjects were tested for urinary albumin to creatinine ratio (ACR); hematuria by microscopy of urinary sediment; and GFR estimated by modified MDRD equation for Chinese adults (eGFR). The related risk factors of CKD were also investigated. Results A total of 4522 subjects were enrolled in the study. The prevalence of albuminuria was 7.11％, hematuria was 2.64％ and reduced eGFR [60 ml-min-1·(1.73 m2)-1] was 2.75％. The prevalence of hypertension was 38.90％; hyperglycemia 6.61％; hyperlipidemia 2.72％; increased waist 24.79％ and metabolic syndrome 15.02％. After the subjects with combined microalbuminuria, hematuria and reduced eGFR were excluded, the prevalence of CKD was 12.95％. Logistic regression analysis and stratified analysis showed increased age, increased waist, elevated systolic pressure, hyperglycemia,hypertriglyceridemia and metabolic syndrome were independently associated with albuminuria;increased age, elevated systolic pressure and hyperglycemia were independently associated with reduced eGFR; increased age was independently associated with hematuria. Conclusions The prevalence of adult CKD is 12.95％ in the Hulunbeir Prefecture, Inner Mongolia Autonomous Region. Independent risk factors of CKD include increased age, increased waist, hypertension,abnormal blood glucose or lipid, and metabolic syndrome.

This paper was designed to study metabonomic characters of the osteoporosis induced by high dose of hydrocortisone and the protective effects of Drynariae Rhizoma, which can replenish the kidney and strengthen the bones. A urinary metabonomics method based on ultra-performance liquid chromatography coupled with mass spectrometry (UPLC-MS/MS) was developed. Clear separation of healthy control group, model group and treatment group was achieved by using the principal components analysis (PCA) and 9 significantly changed metabolites were identified as potential biomarkers of osteoporosis. Compared with the health control group, the model group rats showed lower levels of creatinine, citric acid, azelaic acid, hippurate, tryptophan and indoxyl sulfate together with higher levels of phenylalanine, cresol sulfate and phenaceturic acid. These changes in urinary metabolites suggest that the disorders of amino acid metabolism, energy metabolism, gut microflora and anti-oxidative damage are related to osteoporosis induced by high dose of hydrocortisone and the potential effect of Drynariae Rhizoma on all the four metabolic pathways.
