BACKGROUND:Currently, there are large numbers of studies related to the association between colagen type I alpha1 (COL1A1) Sp1 polymorphism and bone mineral density and fracture risk, but the results are inconsistent. OBJECTIVE:To evaluate the impact of the COL1A1 Sp1 polymorphism on bone mineral density and fracture by using the Meta-analysis. METHODS:We comprehensively searched the eligible studies for the present meta-analysis through MEDLINE, PubMed, EMBASE databases. Pooled odds ratios and 95% confidence intervals of Sp1 polymorphisms for bone mineral density and fracture risk were obtained, with attention to study quality and publication bias. RESULTS AND CONCLUSION:A total of 32 studies met the inclusion criteria, among which, 22 studies evaluated the Sp1 polymorphism and fracture risk. Significant associations were found in five genetic models. In the stratified analysis by region, the same results were found in the Europeans but not Americans and Asians. Thirteen studies evaluated the Sp1 polymorphism and low bone mineral density risk. A similar result was obtained. However, the analysis of bone mineral density data showed an increased relation between Sp1 polymorphism and low bone mineral density in Europeans and Americans but not in Asians. Overal, the current meta-analysis concludes that the COL1A1 Sp1 polymorphism is associated with low bone mineral density and fracture risk, especialy in Europeans. However, susceptibility to them varies markedly among populations from different regions.

Objective To investigate the value of serum proteomic profiling in cervical cancer detected pre-surgery and post-surgery. Methods Magnetic bead and matrix-assisted laser desorption/ionization-time of flight-mass spectrometry (MALDI-TOF-MS) were used to detect the serum samples from 54 cases with cervical cancer before and after surgery and 53 serum samples from healthy women. The results of spectra were analyzed by Biomarker Wizard software. Results Significant variation of proteomic profiling between pre-surgery and post-surgery were analyzed. There were 22 proteins with different mass/charge (M/Z) values significantly different (P<0.01) at the M/Z value range from 1500 to 50 000, among of which relative content of proteins with M/Z 3981, 4290, and 28 066 in pre-surgery cervical cancer patients were higher than those in health women [(1.51±1.78)% vs (0.83±0.38)%, (2.70±2.19)% vs (1.72±0.91)%, (1.99±1.70)% vs (0.92±0.95)%; P<0.01], while in the post-surgery patients, relative content of these three proteins significantly decreased to (0.59±0.45)%, (1.01±0.64)%, (0.54±0.37)%, respectively. But the relative content of another three proteins with M/Z 11 487, 11 529, and 11 678 were significantly increased in post-surgery patients [(0.38±1.41)% vs (2.74±3.67)%, (0.16±0.46)% vs (2.00±1.76)%, (1.02±1.67)% vs (7.71±9.46)%; P<0.01]. Conclusion Serum proteomic profiling could screen out the proteins which had significant variation between pre-surgery and post-surgery serum, of which with M/Z 3981, 4290, and 28 066 may be related with tumor burden, while with M/Z 11 487, 11 529, and 11 678 may be response to surgical stress.

Objective:To systematically synthesize qualitative research on the role expectations of nursing master student's supervisors to provide a reference for improving supervisor team development and optimizing selection and evaluation systems.Methods:A systematic search was conducted in databases such as Web of Science, PubMed, Cochrane Library, Embase, China National Knowledge Infrastructure, Wanfang, VIP, and SinoMed for qualitative studies on the role expectations of nursing master student's supervisors. The search was limited to studies published up to October 31, 2023. The quality of the included studies was evaluated using the Joanna Briggs Institute Critical Appraisal Checklist for Qualitative Research. Meta-integration was employed to synthesize the results.Results:A total of nine studies were included, yielding 39 research findings, which were further categorized into eight new categories. These were integrated into three main themes: expectations of supervisors' comprehensive qualities, clear role positioning and exemplification, and respecting and meeting students' developmental needs.Conclusions:Educational institutions and policymakers involved in graduate education should fully understand the multi-dimensional role expectations of stakeholders regarding nursing master student's supervisors. This understanding is crucial for strengthening the development of the supervisor team, improving selection and evaluation systems, and supporting the training of advanced nursing professionals.

Objective:To assess the translation activity of circ-PTPN22, and to investigate its relationship with systemic lupus erythematosus (SLE) .Methods:From May 10, 2019 to September 30, 2019, whole blood samples were collected from 6 female patients with SLE and 9 healthy female controls in the Department of Rheumatology and Immunology, Integrated Traditional Chinese and Western Medicine, and Physical Examination Center of Southwest Hospital, respectively. Peripheral blood mononuclear cells (PBMCs) were isolated from these blood samples, and PBMCs from 3 cases of SLE and 3 healthy controls were sorted into T, B and NK cells by using magnetic beads. The circ-PTPN22 internal ribosomal entry site (IRES) sequence and protein sequence translated from it were predicted in the circRNADb database, rabbit anti-circ-PTPN22pro polyclonal antibodies were prepared against the specific amino acid sequence at the circ-PTPN22 splice site, and Western blot analysis was performed to determine the protein expression of circ-PTPN22pro in PBMCs and T, B and NK cell subsets of the healthy controls and patients with SLE. Cultured Jurkat cells were divided into 4 groups to be transfected with recombinant lentiviral vectors carrying circ-PTPN22-FLAG, circ-PTPN22-NC-FLAG, circ-PTPN22-shRNA-FLAG, circ-PTPN22-shRNA-NC-FLAG respectively, with the normally cultured cells as the cell control group. Then, Western blot analysis was performed to determine the protein expression of circ-PTPN22pro in Jurkat cells, flow cytometry to evaluate the effect of circ-PTPN22 on cell activation and apoptosis. Statistical analysis was carried out by using two-way repeated measures analysis of variance and two-independent-sample t test. Results:Based on the circRNADb database, circ-PTPN22 was predicted to have a translation ability, and Western blot analysis showed that the relative molecular mass of circ-PTPN22pro was 20 000. Forty-eight hours after transfection, circ-PTPN22pro expression was significantly higher in the circ-PTPN22-FLAG group than in the circ-PTPN22-NC-FLAG group and cell control group. At 24, 48 and 72 hours after transfection, the interleukin 2 (IL-2) expression was significantly lower in the circ-PTPN22 group (22.20% ± 8.92%, 31.10% ± 5.88%, 53.20% ± 10.25%, respectively) than in the circ-PTPN22-NC Group (30.90% ± 11.00%, 51.23% ± 10.70%, 69.67% ± 9.00%, respectively; F = 284.881, P = 0.003) , but significantly higher in the circ-PTPN22-shRNA group (35.57% ± 8.79%, 78.10% ± 10.08%, 88.63% ± 3.89%, respectively) than in the circ-PTPN22-shRNA-NC group (26.73% ± 4.92%, 41.03% ± 10.45%, 41.33% ± 4.96%, respectively; F = 293.818, P = 0.003) . After 48, 72 and 96 hours after transfection, the apoptosis rate was significantly higher in the circ-PTPN22 group than in the circ-PTPN22-NC group ( F = 81.287, P = 0.012) , as well as in the circ-PTPN22-shRNA group than in the circ-PTPN22-shRNA-NC group ( F = 111.813, P = 0.009) . The SLE group showed decreased (almost no) circ-PTPN22pro expression in PBMCs compared with the healthy control group. The circ-PTPN22pro expression in T and B cells was significantly lower in the SLE group than in the healthy control group ( t = 3.047, 4.806, both P <0.05) , and there was no significant difference in the circ-PTPN22pro expression in NK cells between the two groups ( t = 0.582, P > 0.05) . Conclusions:Circ-PTPN22 can be translated into circ-PTPN22pro protein, and can inhibit the activation of Jurkat cells. The circ-PTPN22pro expression is lower in PBMCs of the SLE patients than in those of the healthy controls, suggesting that circ-PTPN22 may be related to the occurrence and development of SLE.
