Objective To investigate the expression level and clinical application value of serum resistin in patients with systemic lu-pus erythematosus(SLE).Methods Forty-five SLE patients visited Nanjing Drum Tower Hospital,Clinical College of Nanjing Uni-versity of Chinese Medicine from January to August 2023 were enrolled in the study.The patients were scored and grouped according to the SLE disease activity index(SLEDAI),with SLEDAI＜9 score in the inactive group(n=32)and SLEDAI≥9 score in the active group(n=13).Thirty-four healthy individuals who underwent physical examination in our hospital were recruited as healthy controls.The clinical data and laboratory related indicators such as urine protein and serum complement C3 levels were collected from SLE pa-tients and healthy controls.Serum resistin levels were detected by enzyme-linked immunosorbent assay(ELISA).The clinical screening value of serum resistin for SLE was evaluated with the receiver operating characteristic(ROC)curve.The correlations of serum resistin levels with different laboratory indicators were determined by Pearson correlation analysis.Results The serum resistin levels in SLE patients([7.64±0.64]ng/mL)were significantly higher than that in healthy controls([2.56±0.43]ng/mL),and the difference was statistically significant(t=6.195,P＜0.01).The serum resistin levels in active SLE patients([10.10±1.45]ng/mL)were significant-ly higher than that in inactive SLE patients([6.64±0.60]ng/mL),and the difference was statistically significant(t=2.632,P＜0.05).The area under the ROC curve(AUCROC)of serum resistin for screening SLE was 0.897.When the cut-off value was 5.893 ng/mL,the sensitivity was 86.67%and the specificity was 82.35%.The serum resistin level in SLE patients was positively correlated with urine protein(r=0.692,P＜0.01),while negatively correlated with serum complement C3(r=-0.354,P＜0.05).Conclusion The expression levels of serum resistin in SLE patients are significantly increased and positively correlated with SLE disease activity and urine protein.Serum resistin may become a novel biomarker for the diagnosis and therapeutic effect assessment of SLE.

AIM: To identify the differentially expressed lncRNAs related to myelodysplastic syndromes by method of bioinformatics. METHODS: The GSE145733 was downloaded from GEO database; the differentially expressed lncRNAs were screened out by GEO2R. miRNA and mRNA associated with the differentially expressed lncRNAs were analyzed by the platform miRDB. lncRNA-miRNA-mRNA network was constructed and visualized by Cytoscape software. We annotated and enriched the lncRNAs to biological functions and pathways by GO and KEGG tools. RESULTS: Five differentially expressed lncRNAs were screened out. These lncRNAs were associated with 19 miRNAs and 84 mRNAs. They mainly affected the functions such as substance synthesis and transportation, gene transcription, and nervous system. CONCLUSION: We discovered the lncRNA expression characteristics in MDS patients, predicted the functions of these lncRNAs, which may provide new drug targets for the precise medication in MDS.

Objective:To explore the effects of phloroglucinol on transfer outcome of in vitro fertilization-embryo transfer (IVF-ET). Methods:Retrospective analysis of 4289 cases of infertility patients treated with IVF-ET in the Department of Reproductive Medicine, the Second Affiliated Hospital of Zhengzhou University from January 1, 2015 to November 30, 2018 was performed. According to the pregnancy outcome, all patients were divided into pregnancy group and non-pregnancy group to analyze the risk factors affecting the pregnancy outcome. According to medication before transfer, all patients were divided into no medication group (group A), preoperative intravenous infusion of atosiban group (group B), preoperative and intraoperative injection of atosiban group (group C) and interoperative intravenous infusion of phloroglucinol group (group D). The pregnancy outcomes, occurrence of adverse reactions during and after treatment were compared among the four groups.Results:Age, number of high-quality embryos, and medication methods before transfer were independent factors influencing pregnancy outcomes in patients undergoing IVF-ET ( P=0.031, P=0.039, P=0.020). The embryo implantation rate, the biochemical pregnancy rate and the clinical pregnancy rate of group D were significantly higher than those in group A (all P<0.001), group B (all P<0.001) and group C ( P<0.001， P<0.001， P=0.001), while the ectopic pregnancy rate was significantly lower than that in group A, group B and group C (all P<0.001). The abortion rate in group D was lower than that in group A ( P<0.001). During treatment period and after treatment, there were no discomfort complains and allergic reactions in the four groups. There were no birth defects in all born babies. Conclusion:The medication method is an independent factor influencing pregnancy outcomes of patients undergoing IVF-ET. Intraoperative intravenous infusion of phloroglucinol can significantly increase embryo implantation rate and pregnancy rate of IVF-ET patients, and reduce their abortion rate.

Objective To investigate the abnormality of intrahepatic biliary epithelial cells autophagy in primary biliary cirrhosis (PBC) mice,and explore the mechanism of UC-Mesenchymal stem cell (MSCs) in treating PBC.Methods After establishing the PBC model,we divided them into the PBC model group;the UC-MSCs treatment group and the Stattic group [Signal transducer and activator of transcription 3 (STAT3) inhibitor group].Six mice were used as the control group.Liver pathology and the serum pyruvate dehydrogenase complex E2 subunit (PDC-E2) antibody titers were detected.Autophagosome of the intrahepatic biliary epithelial cell was observed by electronic microscope.Protein levels of STAT3/pSTAT3,Beclin-1 were detected by western blot.We cultured human intrahepatic biliary epithelial cells in vitro,and down regulated STAT3.After stimulated by GCDC,we co-cultured them with UC-MSCs,and collected the cells in order to detect LC3 Ⅱ.The measurement data were compared with t test or single factor analysis of variance.Results Compared with the control group,periportal inflammatory cell infiltration and granuloma formation were observed in the PBC group.MSCs treatment decreased the infiltration of inflammatory cells.The level of antiPDC-E2 of the PBC group (107±18) ng/ml was higher than that of the control group (42±6) ng/ml (q=6.326,P＜0.01),MSCs treatment down regulated anti-PDC-E2 level (43±4) ng/ml (q=5.801,P＜0.01).More autophagosomes in the PBC group (5.00±1.29) than the control group (1.75±0.25) were observed (q=4.061,P＞0.05).Western blot showed that the level of Beclin-1 was higher in PBC group (1.80±0.36) than the control group (0.40±0.20) (q =6.757,P＜0.01),MSCs reduced the expression of Beclin-1 (0.86±0.06)(q=4.536,P＜0.05) as well as Stattic (0.72±0.03) (q=5.226,P＜0.05).PBC group had a higher expression level of STAT3 (1.80±0.42) (q=5.730,P＜0.05) and pSTAT3 (2.04±0.29)(q=6.492,P＜0.01) than the control group (0.50±0.05)(0.91±0.14).MSCs treatment decreased the expression of STAT3 (0.51±0.13)(q =5.703,P＜0.01) and pSTAT3 (0.76±0.07) (q =7.388,P＜0.01) in intrahepatic biliary epithelial cells.After down regulated STAT3 of HiBECs,MSCs reduced the expression of LC3 Ⅱ of HiBECs.Conclusion The intrahepatic biliary epithelial cells autophage of PBC mice is abnormal,MSCs can alleviate PBC by down regulating the autophage of intrahepatic biliary epithelial cells via STAT3.

OBJECTIVETo explore the molecular mechanism underlying the DEL phenotype among RhD negative ethnic Han individuals from Jiangsu, China.

METHODSThe DEL phenotype was determined by an adsorption elution test among 57 RhD negative blood donors. The Rh C, c, E, and e phenotypes were detected by a tube method. PCR with sequence-specific primering (PCR-SSP) assay was used to determine the RHCE genotypes. The RHD gene of the DEL individuals were amplified with polymerase chain reaction and subjected to Sanger sequencing analysis.

RESULTSAmong the 57 RhD negative donors, 10 (17.54%) were determined as having the DEL phenotype. The major RhCE phenotypes for DEL and RhD negative cases were RhCcee (80.0%) and Rhccee (61.7%), respectively. All RHD gene sequences of the 10 individuals have harbored a G>A mutation at position 1227 of exon 9.

CONCLUSIONA proportion of RhD negative individuals determined by routine serological method are actually DEL with RHD gene mutations. RHD *1227A is the most prevalent DEL genotype among ethnic Han Chinese from Jiangsu. Further research on the phenotype and underlying molecular mechanism of DEL is important for blood transfusion.

Objective To investigate the effect of phosphoinositide-3-kinase inhibitor LY294002 on the differentiation of human embryonic stem cells (HESC) into more mature insulin-producing cells. Methods HESCs were induced to differentiate into insulin-producing cells through five stages. Nicotinamide and B27 (group B27), nicotinamide and LY294002 (group LY) were used to induce the nesting positive cells into mature insulin-producing cells. The morphological change of each stage was observed under microscope , and expressions of insulin, c-peptide, somatostatin and glucagon were identified by immunofluorescence staining. Results After 14 days in stage 5 , there was no significant difference in rate of insulin positive cells between group LY and group B27 (P﹥0.05), but rates of somatostatin and glucagon positive cells in group LY were lower than those in group B27(P﹤0.05). Furthermore, the co-stained rate of somatostatin and insulin in group LY was also lower than that in group B27 (P﹤0.05). Conclusion HESCs can be induced to differentiate into more mature insulin-producing cells by phosphoinositide-3-kinase inhibitor LY294002 in serum-free culture medium.

BACKGROUNDThe clinical applications of fibrin glue span over several surgical modalities. The aim of this study was to evaluate the biocompatibility and biodegradation of different formulations of platelet-rich fibrin glue in vivo and examine its effects on the neovascularization of wound sites.

METHODSHuman-derived single-unit fibrin glue was prepared. Incisions were made on the backs of rats, and these were coated with homemade glues containing different concentrations of aminomethylbenzoic acid (Groups A-F) or commercial adhesives (Group G). A sham control group was included (Group H). The wounds were examined by histological analysis and immunohistochemistry at several time points.

RESULTSSuccessful wound closure was achieved in all groups by day 12. Acute inflammation occurred during the first six days, but gradually disappeared. The longest sealant duration was achieved using the lowest concentration of anti-fibrinolytic agent in a 1:10 volume ratio with cryoprecipitate. Expression levels of the platelet endothelial cell adhesion molecule-1 were significantly higher in Groups A and C compared to the control groups (Groups G and H) on day 3 (P < 0.05).

CONCLUSIONSSingle-unit platelet-rich fibrin glue has excellent biocompatibility and is associated with the upregulation of neovascularization. The addition of aminomethylbenzoic acid could prevent the degradation of fibrin glue.
