    Objective: To investigate the relationship between the activity and gene polymorphism of coagulation factor Ⅻ and the risk of recurrent spontaneous abortion (RSA) in Baotou Han population. Methods: RSA patients and healthy pregnant women were selected as the research objects. The activity of coagulation factor Ⅻ was measured. The genotype composition of FⅫ gene single nucleotide polymorphism (SNP) rs1801020 was analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The results of the two groups were analyzed to determine the correlation between FⅫ gene SNP rs1801020 and RSA under different genetic models. Results: There were significant differences in the genotype and allele frequency distribution of SNP rs1801020 in FⅫ gene between the two groups (P＜0.05); the frequency of T allele in RSA group was lower than that in control group (χ2=8.756, OR=2.043, 95%CI: 1.267-3.295,P<0.05); the frequency of CT genotype in RSA group was higher than that in control group, while the frequency of TT genotype was lower than that in control group, and the difference was statistically significant (χ2=9.905, OR=2.611, 95%CI: 1.447-4.713,P＜0.05); FⅫ activity in RSA patients was different among rs1801020 genotypes, and the order of activity was CC, CT and TT. FⅫ SNP rs1801020 was associated with the risk of RSA under codominant, dominant and overdominant models (OR=2.611, 2.636, 2.470, P＜0.05); compared with TT genotype, CT and CT+CC genotypes could increase the risk of RSA; compared with CC+TT genotype, CT genotype could increase the risk of RSA. Conclusion: The difference in the distribution of FⅫ rs1801020 between the two groups may be related to the risk of RSA in Baotou Han women. Compared with TT genotype, mutant heterozygous CT genotype may increase the risk of RSA, the T allele of rs1801020 locus of FⅫ gene can cause the decrease of FⅫ activity.

    Objective: To explore whether triptolide can alleviate the disease by reducing the infiltration of neutrophils in the joint cavity of collagen-induced arthritis (CIA) mice, and to analyze whether triptolide can reduce the formation of neutrophil extracellular capture networks (NETs) in patients with rheumatoid arthritis (RA) and its mechanism of action, so as to provide theoretical support for the clinical application of tripterygium glycosides in RA. Methods: The core targets of Tripterygium wilfordii intervention in RA disease were explored by using the public database of network medicine. After the CIA model was constructed using DBA1 mice, triptolide was given for 60 days. The hind limbs of the mice were collected for HE staining and the degree of inflammatory cell infiltration in the joint cavity of the mice was observed. Neutrophils in peripheral blood of RA patients were collected and stimulated with triptolide for 2 h. The formation of NETs was observed by immunofluorescence staining. Treatment with triptolide in RA group and triptolide could alleviate joint swelling in CIA mice; triptolide could also inhibit the formation of NETs in peripheral blood neutrophils of RA patients. Transcriptome sequencing was performed on neutrophils in RA group and Tripterygium wilfordii treatment group. Results: Through network pharmacology analysis, PPI protein interaction was performed on the locked overlapping genes, and KEGG and GO analysis were performed. It was found that IL-17, TNF signaling pathway and apoptosis-related pathway were closely related to RA disease. In vivo experiments showed that 389 differential genes were screened from the transcriptome sequencing results of the triptolide treatment group. The GO and KEGG pathways were mainly enriched in JAK-STAT, TNF, and PI3K-Akt signaling pathways. Conclusion: Triptolide can alleviate joint swelling in CIA mice by down-regulating neutrophil infiltration in the joint cavity of CIA mice, and triptolide can reduce the formation of NETs in peripheral blood of RA.This phenomenon may be related to JAK-STAT signaling pathway, TNF signaling pathway, PI3K-Akt and other signaling pathways.

    Objective: To investigate the effect of berberine (BBR),a traditional Chinese medicine extract,on doxorubicin (DOX) induced myocardial cell damage at the cellular level,and explore the possible mechanisms involved in this process. Methods: H9C2 rat cardiomyocytes were cultured,and DOX was divided into different concentrations to determine the concentration of DOX.Then they were divided into normal control group,DOX model group and treatment group (low-dose BBR,medium-dose BBR,high-dose BBR) to treat H9C2 cells. The cell growth trend and cell morphology were observed by inverted microscope. The cell viability was determined by cell counting kit (CCK8) method. The apoptosis was detected by flow cytometry. The relative expression levels of apoptosis and autophagy related proteins Bax,Bcl-2,Beclin1 and P62 in different groups were determined by Western-blot. Results: Under the microscope,it was found that with the increase of DOX concentration,the degree of myocardial cell injury increased in turn. CCK8 method was used to select 1 μmol/L DOX as the optimal modeling concentration for myocardial injury,compared with the control group,different concentrations of BBR in the treatment group could increase the viability of DOX-induced myocardial injury cells. The expression of pro-apoptotic protein Bax and autophagy-related protein Beclin1 in the middle dose of the treatment group was significantly decreased,and the expression of anti-apoptotic protein Bcl-2 and autophagy-related protein P62 was increased (P＜0.05). Conclusion: Berberine can protect DOX-induced cardiomyocyte injury by reducing apoptosis,and this protective mechanism is related to autophagy.

    Objective: To study the expression of lncRNA SNHG10 and methyltransferase METTL3 in colorectal cancer (CRC) tissues and adjacent tissues. Meanwhile, to explore the potential relationship between lncRNA SNHG10 and METTL3 in CRC. Methods: Tumor tissue and paracancerous tissue samples of 15 CRC patients were collected. The expression of lncRNA SNHG10 and METTL3 in CRC was investigated by bioinformatics, real-time fluorescence quantitative PCR (RT-qPCR) and Western blot. The relationship between the relative expression level of lncRNA SNHG10 in colorectal cancer and prognosis was analyzed. The gene interaction was analyzed by TCGA database, ENCORI, cBioPortal website and in vitro inhibition experiment of colon cancer cell line (HCT116). Results: Bioinformatics website and RT-qPCR experiments showed that lncRNA SNHG10 was up-regulated in colorectal cancer compared with adjacent tissues (P＜0.05). The high expression of lncRNA SNHG10 indicated that CRC patients were more likely to have lymph node metastasis, and the disease-specific survival rate and overall survival rate were relatively low (P＜0.05). RT-qPCR and Western blot results confirmed that METTL3 was highly expressed in CRC tumor tissues. In vitro experiments showed that knockdown of lncRNA SNHG10 in HCT116 cells resulted in down-regulation of METTL3 expression at both mRNA and protein levels (P＜0.05). Conclusion: The high expression of lncRNA SNHG10 is associated with tumor progression and poor prognosis. LncRNA SNHG10 is positively correlated with METTL3 and regulates METTL3 expression. This study suggests that SNHG10 may be a promising CRC biomarker and therapeutic target.

    Objective: To observe the clinical effects of Oxford Ⅲ unicompartmental knee arthroplasty (UKA) and total knee arthroplasty (TKA) in the treatment of medial compartment osteoarthritis of the knee joint. Methods: The clinical data of 66 patients with medial compartment osteoarthritis of the knee admitted to the Fourth Hospital of Baotou from January 2018 to January 2021 were selected and divided into observation group and control group (33 patients in each group) according to different surgical methods. The observation group was treated with UKA, and the control group was treated with TKA. The surgical related indexes of the two groups were compared. The femoral-tibial angle (FTA) and range of motion (ROM) of the two groups were compared before and 1 year after operation. The pain and knee function were evaluated by visual analogue scale (VAS) and Hospital for Special Surgery knee score (HSS). And the complications of the two groups. Results: The operation time, incision length and hospitalization time of the observation group were shorter than those of the control group, and the intraoperative blood loss was less than that of the control group (P＜0.05). Before operation, there was no significant difference in FTA, ROM, VAS score and HSS score between the two groups (P＞0.05), while the FTA and VAS scores of the two groups at 1 year after operation were significantly lower than those before operation, and those of the observation group were lower than the control group (P＜0.05). At 1 year after operation, the ROM and HSS scores of the two groups were higher than those before operation, and those of the observation group were higher than the control group (P＜0.05). The total incidence of postoperative complications such as persistent pain, prosthesis shedding, joint stiffness, and lateral compartment osteoarthritis in the observation group (9.09%) was lower than that in the control group (30.30%) (P＜0.05). Conclusion: Compared with TKA, UKA has the advantages of less trauma, shorter operation time, less intraoperative blood loss and faster postoperative recovery in the treatment of medial compartment osteoarthritis of knee joint. Meanwhile, it can improve the femoral-tibial angle, knee joint mobility and knee joint function, effectively reduce the pain of patients, reduce postoperative complications and shorten the hospitalization time. Therefore, it is worthy of popularization and application.

    Objective: To study the correlation between lipoprotein a, ApoE gene polymorphism and cardiac valve calcification, and to explore the role of genotype and lipoprotein a in the disease process. Methods: A total of 412 patients admitted to the Department of Cardiology from July 2021 to December 2022 were selected. The results of lipoprotein a and other blood lipids, ApoE genotype, echocardiography and carotid intima-media thickness (IMT) were collected, and the clinical data such as blood pressure were recorded. At the same time, the history of arrhythmia, heart failure, valvular heart disease and ACS were recorded. The correlation between ApoE genotype and blood lipid, cardiac valve calcification was analyzed. Results: The contents of TC, TG, lipoprotein a and LDL-C in the baseline data of the three groups were statistically different. Compared with the ε3 group, the contents of lipoprotein a and LDL-C in the ε2 group were lower, while those in the ε4 group were higher. Univariate analysis showed that age, HDL-C, TG, lipoprotein a, LDL-C, IMT, history of arrhythmia, history of heart failure, history of valvular heart disease were associated with valvular calcification. Binary logistic regression analysis showed that age, lipoprotein a, IMT and history of arrhythmia were independent risk factors for cardiac valve calcification. There was a correlation between lipoprotein a and cardiac valve calcification in the ε2 and ε3 subgroups, but there was no correlation in ε4 subgroup. The area under the curve for the combined diagnosis of IMT and lipoprotein a to predict cardiac valve calcification was 0.760 (P＜0.001). Conclusion: ApoE genotype does not directly affect the occurrence of calcification, but indirectly affects the disease by changing blood lipids. ε4 may be related to the increase of lipoprotein a and LDL-C. ε2 may be related to the decrease of lipoprotein a and LDL-C. Lipoprotein a may be related to the content of LDL-C.

    Objective: To investigate the relationship between phosphoglycerate kinase 1 (PGK1) and clinicopathological parameters of breast cancer and its prognostic significance. Methods: (1)The matrix data and clinical data of PGK 1 mRNA expression in breast cancer and normal breast tissues were downloaded from TCGA and GEO databases. The relationship between PGK 1 mRNA expression in breast cancer tissues and clinicopathological features was analyzed. Logistics regression was used to evaluate the independent risk factors of PGK 1 mRNA expression. Kaplan-Meier method was used to draw survival curves to analyze the relationship between PGK 1 mRNA expression level and overall survival (OS) of breast cancer patients. (2)From January 2022 to January 2023, 50 cases of breast cancer and normal breast tissue specimens were collected from the Department of Breast Surgery, the First Affiliated Hospital of Baotou Medical College. The expression levels of PGK1 in breast cancer and normal breast tissues were detected by real-time fluorescence quantitative PCR and immunohistochemical staining, respectively. The relationship between PGK 1 expression and clinicopathological parameters in breast cancer tissues was analyzed, and Logistics regression was used to evaluate the independent risk factors related to PGK1 expression. Results: (1)The expression of PGK1 mRNA in breast cancer was significantly higher than that in normal breast tissue (P＜0.05). (2)ER, PR and HER-2 were independent risk factors for PGK1 mRNA expression. (3)The high expression of PGK 1 mRNA was positively correlated with the decrease of overall survival. (4)The expression of PGK 1 in breast cancer was statistically significant. (5)ER, PR and HER-2 were independent risk factors affecting the expression of PGK1. Conclusion: (1)The expression level of PGK1 in breast cancer is significantly increased. (2)The expression of ER, PR, HER-2 is positively correlated with the expression of PGK1. (3) High expression of PGK1 may be a potential predictor of poor prognosis of breast cancer.
