ABSTRACT
Aim To investigate the role of TGF-β/Smad signaling pathway in rheumatoid arthritis (RA) - associated postinterstitial pulmonary fibrosis in mice. Methods The mouse model of RA was constructed by subcutaneous administration of complete Freund's adjuvant (CFA) and chicken II collagen (Col-II) to the tail root of mice. The blank group was given the same amount of distilled water, and the control group was given the same amount of glacial acetic acid (solvent). The degree of toe swelling (joint swelling degree and arthritis index) was monitored to evaluate the mouse modeling. The pathological changes of mouse lung tissues were observed by HE and Masson staining. The expression of TGF-β in lung tissues were observed by immunohistochemical staining. The level of hydroxyproline in lung tissues was measured by chemiluminescence method. The expressions of Smad2, Smad3 and phosphorylated p-Smad2 and phosphorylated p-Smad3 in lung tissues were detected by Western blot. Results Compared with blank group and solvent group, the joint swelling and arthritis index of model group significantly increased. Twenty-one days after administration, HE staining showed inflammatory changes in lung interstitium of the model group, Masson staining showed collagen fiber deposition and obvious fibrosis in lung interstitium of the model group, and immunohistochemical staining showed that the expression of TGF-β in cytoplasm of lung interstitial cells of the model group increased, which was brown and yellow. Meanwhile, hydroxyproline was significantly raised in lung tissue homogenate of the model group. Further WB analysis showed that compared with blank group and solvent group, the expression of p-Smad2 and pSmad3 in lung tissues of the model group was significantly up-regulated (P < 0. 05, P < 0. 01). Conclusions RA can give rise to pulmonary fibrosis, and the expressions of p-Smad2 and p-Smad3 are up-regulated, which is be pivotal in pulmonary fibrosis and RA-related post-interstitial pulmonary fibrosis.
ABSTRACT
Aim To investigate the pharmacological effects of paeonol as a formyl peptide receptor activator on rheumatoid arthritis (HA).Methods The target rlataset was obtained from the high throughput Gene Expression Database ( GEO) , and multiple data sets were combined by USING R language to explore three groups of macrophage differentially expressed genes ( DEGs) in untreated,lipopolysaccharide (LPS) treat¬ment and paeonol and LPS treatment, and their enrich-ment pathway was analyzed.Protein-protein interaction (PPI) networks were constructed in the STRING data¬base anrl visualized in Cytoscape software.The inhibi¬tor}' effect of Hub gene formyl peptide receptor ( FPR) on RA inflammation was validated by TNF-cx stimula¬tion of fibroblast synovial cells ( FLS).Results Through bioinformatics analysis, 169 differential genes ( DEGs) related to inflammation and 275 DEGs related to the mechanism of paeonol action were obtained.Combined analysis of the two groups of DEGs showed that FPR played a key role in the anti-inflammatory mechanism of paeonol.Further studies on the mecha¬nism of paeonol showed that paeonol activated FPR, and the inhibitory effect of paeonol on FLS inflamma¬tion was rescued by TRP-ARg-TRP-TRP-TRP-TRP- TRP-TRP-NH2 (WRW4).Conclusion Paeonol can inhibit the inflammatory development of RA through the FPR pathway.

ABSTRACT
Aim To investigate the possible mechanism of paeonol inhibiting the inflammatory response of fibroblast synovial cells (RA-FLSS) in rheumatoid arthritis. Methods CCK-8 assay was used to detect Paeonol's inhibitory level on the abnormal proliferation of arthritis human fibroblast synovial cells (RA-FLSs). The levels of endoplasmic reticulum stress-related proteins MANF and ATF6 were detected by Western blot. Cell localization of transcription factor p65 and Mesencephalic Astrocyte Derived Neurotrophic Factor (MANF) was detected by immunofluorescence. RT-qPCR detected the changes of p65 target genes. Results Paeonol could significantly inhibit the abnormal proliferation of RA-FLSS cells. Paeonol activates ATF6 and increases the expression of MANF. Paeonol promoted the nuclear transfer of MANF protein and inhibited the transcriptional activity of p65. Conclusion Paeonol promotes the expression of MANF and nuclear transfer through the endoplasmic reticulum stress pathway and affects the progression of RA by inhibiting the transcriptional activity of p65.
ABSTRACT
OBJECTIVE@#To investigate the effects of different routes in placental mesenchymal stem cells (PMSC) on serum expression levels of IL-4, IL-17, TNF-α and IFN-γ in aplastic anemia (AA) rats.@*METHODS@#The rat model of aplastic anemia (AA rats) was established by 5-fluorouracil combined with busulfan. The rats was divided into four groups: control, experimental, PMSC-injected into the tail vein, and PMSC-injected into the medullary cavity. The general state of rats in each group was observed in detail before and after treatment. The serum levels of interleukin-4 (IL-4) , interleukin-17 (IL-17), tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ) were measured by enzyme-linked immunosorbent assay (ELISA) at week 1, 3 and 5 after treatment.@*RESULTS@#The serum levels of TNF-α, IFN-γ and IL-17 in the experimental group were significantly higher than those in the control group, while the level of IL-4 was significantly decreased (P<0.05). The levels of TNF-α, IFN-γ and IL-17 gradually decreased after treatment while the level of IL-4 increased. By the fifth week, the above indexes were closed to the control group (P>0.05), and the levels of TNF-α, IFN-γ and IL-17 in the group with PMSCs injected via the medullary cavity decrease more significantly than those group with PMSC injected via the tail vein, but level of IL-4 was not significantly different between two groups.@*CONCLUSION@#The level of serum hematopoietic negative regulators increase significantly, and the level of hematopoietic promoting factors decreases significantly in aplastic anemia rats. PMSC can down-regulate the level of hematopoietic negative regulators and up-regulate the level of hematopoietic promoting factors in the rats with aplastic anemia, and the inhibition of hematopoietic negative regulators by intramedullary injection is more significant than that by caudal vein injection.

Objective: To study the effect of fertilization combination of nitrogen, phosphorus, and potassium on the yield and quality of Salvia miltiorrhiza in order to explore the optimal N, P, and K ratios and dosages in middle south of Shandong, and provide theoretical guidance for precision fertilization. Methods: Based on “3414” randomized block design, 14 fertilization combination treatments of N, P and K were designed to determine the yield, growth, and bioactive components of S. miltiorrhiza. The effects of different fertilization treatments on the yield and quality of S. miltiorrhiza were analyzed, and a fertilizer effect model of S. miltiorrhiza in middle south of Shandong was established by stepwise regression analysis. The maximum yield of fertilized S. miltiorrhiza and the best amount of economic fertilization were estimated. Results: Nitrogen, phosphorus, and potassium deficiency treatments reduced the yields by 27.29%, 22.09%, and 23.83%, respectively, and the optimal treatment for increasing yield was N2P2K2 with a yield of 16 740 kg/hm2. Single factor fertilizer effect analysis showed that the yield of S. miltiorrhiza showed a trend of increasing first and then decreasing with the increase in the application amount of these fertilizers. The main nutrient elements limiting yield and benefit of S. miltiorrhiza in middle south of Shandong were as follow: N > K > P. The analysis of the interaction between the two factors showed that the nitrogen, phosphorus, and potassium fertilizers promoted each other at a certain application amounts, the interaction effect were as follow: NP > NK > PK. Through the effects of fertilization combination of nitrogen, phosphorus, and potassium on growth, nitrogen significantly promoted the material accumulation in roots of S. miltiorrhiza. Potassium had a certain role in promoting the plant width and root width. The effect of fertilization on the content of active ingredients showed that potassium promoted the accumulation of phenolic acids and tanshinones, while potassium had the adverse effect. Conclusion: The quadratic function fitting result between the amount of fertilizer applied and the yield of S. miltiorrhiza is in line with the law of diminishing returns, which can better reflect the relationship between the amount of fertilizer and yield. The best fertilizer scheme in middle south of Shandong should be N 195.63 kg∙/hm2, P2O5 116.64 kg/hm2, and K2O 153.84 kg/hm2 estimated by ternary quadratic function fitting.

Objective: To understand the distribution and treatment of malaria patients, and the characteristics of sampled hospitals in thephase of eradication of malaria,and provide support for medical resources allocation in the later stages of malaria eradication phase. On this basis, this study aims at promoting the realization of the ultimate goal of total eradication of malaria in China by 2020. Methods : A multi-stage stratified cluster sampling method was used. A total number of 102 hospitals in Zhejiang, Jiangsu, Anhui, Henan, Sichuan and Yunnan Provinces were selected to collect original information on in-patient and out-patient of malaria in terms of medical records and treatment costs during the periodfrom January 1st 2014 toDecember 31th2016. In order to conduct accurate statistical analysis, Excel 2016, SPSS 20. 0 and other Software were used. Results: The survey results collected a total number of 1633 malaria patients, and these patients showed a W-shaped distribution during the months of treatment. Most of malaria patients from Henan and Sichuan Provinceswere diagnosed as having been affected by falciparum and vivax malaria, and their number sharply increased. This is paper also revealed the ratios of malaria patientsin terms of their choice of health services,namely from tertiary hospitals, municipal medical institutions and provincial medical institutions; those were77.10%,52.05% and 23.58%,respectively. Conclusions : A new period of peak incidence of malariais detected from 2014 to 2016. With hospitals' line of malaria defending ability shrinking,it was found that malaria treatment capacitiesare relatively concentrated in the high level hospitals,which plays a greater role when it comes to the prevention and control of malaria. It is recommended that regional malaria treatment lines should be built,and severe malaria treatment knowledge trainingsshould be prepared and attended in mass in orderto improve malaria treatment capacities.
ABSTRACT
Congenital hypothyroidism (CH), which results from insufficient thyroid hormone biosynthesis, is one of the most common neonatal endocrine disorders. Thyroid dysgenesis and thyroid dyshormonogenesis are the two causes of CH and either one will lead to deficiencies of enzymes during thyroid hormone biosynthesis and insufficient thyroid hormone biosynthesis. Recently, researchers have performed extensive studies on genetics of CH. This paper reviews genes reported to be associated with CH in China.

We sought to identify common key regulators and build a gene-metabolite network in different nonalcoholic fatty liver disease (NAFLD) phenotypes. We used a high-fat diet (HFD), a methionine-choline-deficient diet (MCDD) and streptozocin (STZ) to establish nonalcoholic fatty liver (NAFL), nonalcoholic steatohepatitis (NASH) and NAFL+type 2 diabetes mellitus (T2DM) in rat models, respectively. Transcriptomics and metabolomics analyses were performed in rat livers and serum. A functional network-based regulation model was constructed using Cytoscape with information derived from transcriptomics and metabolomics. The results revealed that 96 genes, 17 liver metabolites and 4 serum metabolites consistently changed in different NAFLD phenotypes (>2-fold, P<0.05). Gene-metabolite network analysis identified ccl2 and jun as hubs with the largest connections to other genes, which were mainly involved in tumor necrosis factor, P53, nuclear factor-kappa B, chemokine, peroxisome proliferator activated receptor and Toll-like receptor signaling pathways. The specifically regulated genes and metabolites in different NAFLD phenotypes constructed their own networks, which were mainly involved in the lipid and fatty acid metabolism in HFD models, the inflammatory and immune response in MCDD models, and the AMPK signaling pathway and response to insulin in HFD+STZ models. Our study identified networks showing the general and specific characteristics in different NAFLD phenotypes, complementing the genetic and metabolic features in NAFLD with hepatic and extra-hepatic manifestations.
