Pulmonary fibrosis is a severe lung interstitial disease characterized by the destruction of lung tissue structure, excessive activation and proliferation of fibroblasts, secretion and accumulation of a large amount of extracellular matrix (ECM), and impaired lung function. Due to the complexity of the disease, a suitable animal model to mimic human pulmonary fibrosis has not yet been established. Precision-cut lung slice (PCLS) has been a widely used in vitro method to study lung physiology and pathogenesis in recent years. This method is an in vitro culture technology at the level between organs and cells, because it can preserve the lung tissue structure and various types of airway cells in the lung tissue, simulate the in vivo lung environment, and conduct the observation of various interactions between cells and ECM. Therefore, PCLS can compensate for the limitations of other models such as cell culture. In order to explore the role of discoidin domain receptor 2 (DDR2) in pulmonary fibrosis, Ddr2^flox/flox mice were successfully constructed. The Cre-LoxP system and PCLS technology were used to verify the deletion or knockdown of DDR2 in mouse PCLS. Transforming growth factor β1 (TGF-β1) can induce fibrosis of mouse PCLS in vitro, which can simulate the in vivo environment of pulmonary fibrosis. In the DDR2 knock down-PCLS in vitro model, the expression of various fibrosis-related factors induced by TGF-β1 was significantly reduced, suggesting that knocking down DDR2 can inhibit the formation of pulmonary fibrosis. The results provide a new perspective for the clinical study of DDR2 as a therapeutic target in pulmonary fibrosis.

Abstract：Objective To predict the structure and function of sterol O⁃acyltransferase 1（SOAT1）related to hepatocellular carcinoma（HCC）by using bioinformatics tools，in order to understand its mechanism as the marker and therapeutic target of S⁃Ⅲ subtype. Methods The structure，function and protein interaction of SOAT1 were predicted and analyzed by using databases or softwares such as NCBI，STRING，Protscale，SignalP，TMHMM，PSORT，SOPMA，SWISS ⁃ MODEL， NetNGlyc，NetOGlyc，Netphos and ProtParam. Results The protein encoded by SOAT1 was a hydrophobic protein with good stability，which was a nonclassical pathway protein with 8 transmembrane regions，mainly distributed among the cell membrane. SOAT1 was expressed in many tissues，while most of them in the adrenal gland，which showed multiple phosphorylation sites and was mainly involved in the synthesis and catabolism of cholesterol. Conclusion Bioinformatics analysis of structure and function of SOAT1 showed that SOAT1 lipid synthesis and catabolism pathways played an important role，and lipid expression was closely related to the development of cancer，indicating that the treatment of HCC may be achieved by regulating the expression of SOAT1 gene.

OBJECTIVES: To estimate the system efficiency of uncle-nephew relationship identification by increasing STR markers and adding reference samples based on the test results of simulated data and real samples, so as to provide references for selecting the appropriate number of STRs and reference samples for uncle-nephew relationship identification. METHODS: Five common models of uncle-nephew relationship identification were constructed by adding different reference samples. In each model, the likelihood ratio (LR) for 10 000 pairs of uncle-nephew relationships and 10 000 pairs of unrelated individuals were simulated by detecting 19, 39 or 55 STRs, and the system efficiency at different thresholds was simulated. The samples of the Han population in Zhejiang were collected, and 55 autosomal STRs were obtained by using SiFaSTR^TM 23plex kit, Goldeneye^® DNA ID 22NC kit and AGCU 21+1 PCR amplification kit. When 19, 39 and 55 STRs were detected, the LR of each model and system efficiency under different thresholds were calculated and compared with the simulation results. RESULTS: Under the same detection system, the calculated results of simulated data and corresponding true samples were basically consistent. In the same model, there was a positive correlation between the system efficiency of uncle-nephew relationship identification and the number of STRs detected. Moreover, the system efficiency of introducing relatives was higher than identifying only two individuals. The order of preference for the introduction of relatives was the full sibling (or mother) of the uncle and the full sibling (or mother) of the nephew. CONCLUSIONS The system efficiency of uncle-nephew relationship identification could be improved by increasing the number of STRs and introducing known relatives, which would provide the basis for selecting the most appropriate detection system and reference individuals in actual cases.

OBJECTIVE: To study insulin sensitivity and the serum level of adiponectin in infants with intrauterine growth retardation (IUGR) and the effect of breastfeeding on the insulin sensitivity through a follow-up study. METHODS: A total of 106 full-term IUGR infants who were hospitalized from October 2014 to October 2018 were enrolled as the IUGR group, and 90 full-term appropriate for gestational age (AGA) infants who were born during the same period of time were enrolled as the AGA group. Birth weight and body length were recorded. Serum levels of fasting blood glucose (FBG), triglyceride (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), insulin, and adiponectin were measured on day 7 after birth. Homeostasis model assessment of insulin resistance (HOMA-IR) was calculated. According to the feeding pattern, the IUGR group was further divided into a breastfeeding group with 37 infants and a formula feeding group with 42 infants. The above serum indices and growth indices were also measured at the age of 3 and 6 months. RESULTS: Compared with the AGA group, the IUGR group had significantly increased levels in serum insulin and HOMA-IR and a significantly decreased level of adiponectin (P<0.05). There were no significant differences between the breastfeeding and formula feeding groups in growth indices and serum levels of FBG, TG, LDL, and HDL on day 7 after birth and at the ages of 3 and 6 months (P>0.05). In the breastfeeding group, serum insulin and HOMA-IR decreased and adiponectin level increased over the time of breastfeeding (P<0.05). CONCLUSIONS Insulin sensitivity decreases in the early stage after birth in IUGR infants, and breastfeeding can improve insulin sensitivity.

Macrophages show significant heterogeneity in function and phenotype, which could shift into different populations of cells in response to exposure to various micro-environmental signals. These changes, also termed as macrophage polarization, of which play an important role in the pathogenesis of many diseases. Numerous studies have proved that Hesperidin (HDN), a traditional Chinese medicine, extracted from fruit peels of the genus citrus, play key roles in anti-inflammation, anti-tumor, anti-oxidant and so on. However, the role of HDN in macrophage polarization has never been reported. Additional, because of its poor water solubility and bioavailability. Our laboratory had synthesized many hesperidin derivatives. Among them, hesperidin derivatives-12 (HDND-12) has better water solubility and bioavailability. So, we evaluated the role of HDND-12 in macrophage polarization in the present study. The results showed that the expression of Arginase-1 (Arg-1), interleukin-10 (IL-10), transforming growth factor β (TGF-β) were up-regulated by HDND-12, whereas the expression of inducible Nitric Oxide Synthase (iNOS) was down-regulated in LPS- and IFN-γ-treated (M1) RAW264.7 cells. Moreover, the expression of p-JAK2 and p-STAT3 were significantly decreased after stimulation with HDND-12 in M1-like macrophages. More importantly, when we taken AG490 (inhibitor of JAK2/STAT3 signaling), the protein levels of iNOS were significantly reduced in AG490 stimulation group compare with control in LPS, IFN-γ and HDND-12 stimulation cells. Taken together, these findings indicated that HDND-12 could prevent polarization toward M1-like macrophages, at least in part, through modulating JAK2/STAT3 pathway.

Objective: To explore the expression of amphiregulin (AREG) in nasal polyps patients with different degrees of eosinophil infiltration, and to analyze the correlation between AREG and tissue remodeling. Methods: Forty-eight patients underwent endoscopic sinus surgery in the Department of Otorhinolaryngology Head and Neck Surgery, Remin Hospital, Wuhan University from July 2017 to August 2018 were recruited, including 40 males and 8 females, aged from 16 to 60 years old. The subjects were divided into three groups: control group (n=14), eosinophilic chronic sinusitis with nasal polyps (ECRSwNP) group (n=19) and noneosinophilic chronic rhinosinusitis with nasal polyps (non-ECRSwNP) group (n=15). The relative expression of AREG in nasal mucosa was detected by Western blot assay and immunohistochemical staining. Tissue remodeling was detected by HE staining, AB-PAS staining and Masson staining. Kruskal-Wallis test was used for comparison among multiple groups, and Spearman correlation analysis was conducted between the expression level of AREG and the related indexes of tissue remodeling. Results: The expression of AREG in ECRSwNP group was significantly higher than that in non-ECRSwNP group and control group (median protein expression of Western blot was 1.592 vs 0.617 vs0.582, all P<0.05). The degree of epithelial injury and goblet cell metaplasia in ECRSwNP group was significantly higher than that in control group (all P<0.05), the percentage of collagen fibrosis area in ECRSwNP group was significantly lower than that in control group (P=0.01). In chronic rhinosinusitis with nasal polyps (CRSwNP) patients, the area of mucous glands was negatively correlated with the expression of AREG (r=-0.616, P<0.05), and the percentage of collagen fibrosis area was negatively correlated with the expression of AREG (r=-0.738, P<0.05). Conclusion The expression of AREG is higher in ECRSwNP patients, which is related to the process of tissue remodeling.

Objective　CARD9 can activate several pathways involved in immunity, such as NF-ΚB, MAPK, etc. However the mechanism of this process has not yet been elucidated. For conducting relevant experiments in vitro, a prokaryotic expression vector of CARD9-MBP fusion protein has to been construct, and the fusion protein need to be expressed and purified.　Methods　The coding sequence of CARD9 and MBP genes were amplified by PCR and the recombinant plasmid was correctly inserted into the pET-30a(+) vector. The recombinant plasmid was transformed into E.coli DH5α competent cells and proceeded PCR identification, restriction analysis and gene sequencing. The correct recombinant plasmid was transformed into E.coli BL21(DE3) competent cells. The target protein was induced to express by IPTG under different conditions. Relative molecular weight of the target protein was detected by SDS-PAGE electrophoresis. The CARD9-MBP fusion protein was purified by MBP maltose chromatography column and gel filtration chromatography column, and identificated by MALDI-TOF mass spectrometry after MBP-tag to be removed by HRV3C enzyme.　Results　The CARD9-MBP fusion protein was successfully constructed and confirmed by PCR and restriction analysis. The result of gene sequencing was consistent with the target sequence. The SDS-PAGE electrophoresis showed that the target protein with molecular mass (MR) about 105 000 was successfully induced to express in E.coli BL21 (DE3). A quite pure CARD9-MBP fusion protein was obtained by purification of MBP maltose chromatography column. Identification by MALDI-TOF mass spectrometry demonstrated that the target protein after MBP-tag to be removed by HRV3C enzyme is CARD9 protein. In the later stage, gel filtration chromatography column was used to obtain further pure CARD9-MBP fusion protein.　Conclusion　The prokaryotic expression vector of CARD9-MBP fusion protein was successfully constructed and a large number of soluble protein expressed. The purified target protein can be obtained by purification with MBP maltose chromatography column and gel filtration chromatography column.
