Objective: To investigate the effects of recombinant human granulocyte colony-stimulating factor (rhG-CSF) combined with arsenic trioxide (ATO) (molecular formula: As2O3) on the proliferation and apoptosis of acute myeloid leukemia (AML) cells, and to explore the possible mechanisms. Methods: AML cells HL-60 and THP-1 were pre-treated with rhG-CSF (100 ng/mL), and then treated with different concentrations of As2O3. The relative proliferation rate was detected by CCK-8 method, while the apoptosis and cell cycle distribution were measured by FCM method. The expression levels of aquaporin 9 (AQP9) mRNA and protein in HL-60, THP-1 and acute promyelocytic leukemia NB4 cells as well as HL-60 and THP-1 cells treated with rhG-CSF (100 ng/ mL) were detected by real-time fluorescent quantitative PCR and Western blotting, respectively. Results: RhG-CSF promoted the proliferation of HL-60 and THP-1 cells (both P < 0.01). Compared with the As2O3 group, rhG-CSF pre-treatment combined with 2 μmol/L As2O3 inhibited the proliferation of HL-60 and THP-1 cells (both P < 0.05), rhG-CSF combined with different concentrations of As2O3 increased the apoptotic rates of HL-60 and THP-1 cells (both P < 0.05). As2O3 caused G0/G1 arrest in HL-60 and THP-1 cells (both P < 0.05). rhG-CSF caused S-phase arrest in HL-60 and THP-1 cells (both P < 0.01), the effect was more obvious in rhG-CSF combined with As2O3 group (both P < 0.05). The expressions of AQP9 mRNA and protein in HL-60 and THP-1 cells were lower than those in NB4 cells (all P < 0.01). Compared with the untreated control group, 100 ng/mL rhG-CSF up-regulated the expression levels of AQP9 mRNA and protein in HL-60 and THP-1 cells (all P < 0.05). Conclusion: RhG-CSF can increase the sensitivity of non-M3 AML cells to As2O3, which may be associated with the up-regulation of AQP9 expression.

PURPOSE: Numerous previous studies have reported inconsistent results about the differences between synchronous contralateral breast cancer (sCBC) and metachronous contralateral breast cancer (mCBC). This study aimed to compare the clinical characteristics and outcomes between sCBC and mCBC and determine predictive factors for the survival of sCBC and mCBC patients. METHODS: Using the Surveillance, Epidemiology, and End Results Program database, we identified sCBC or mCBC patients from 2000 to 2010. The Kaplan-Meier method and Cox proportional hazards regression analysis were used to analyze overall survival and breast cancer-specific survival (BCSS) rates of sCBCs and mCBCs, respectively. RESULTS: Overall, 14,057 sCBC (n = 8,139, 57.9%) and mCBC (n = 5,918, 42.1%) patients were included. The first tumors of sCBC were more likely to have higher stage and more lymph and distant metastases, whereas those of mCBC were more often infiltrating ductal carcinoma (IDC), had localized stage, were estrogen receptor (ER) and progesterone receptor (PR) negative, and had less axillary nodal involvement. The second tumors of mCBC tended to be IDC and have higher grade, adverse stage, ER and PR-negativity; and more axillary nodal involvement, compared to the second tumors of sCBC. mCBC patients had significantly favorable 5-year BCSS but worse long-term BCSS compared with sCBC patients. Moreover, subgroup analysis revealed no significant difference of BCSS between sCBC and mCBC among patients aged 18–60 years. Multivariate analysis indicated that age, grade, and stage of 2 tumors; surgery for second tumor; and ER status of the second tumor were independent prognostic factors for BCSS of contralateral breast cancer (CBC). CONCLUSION: The characteristics and outcomes of sCBCs and mCBCs were substantially different. sCBC and mCBC patients may have different prognosis, and the prognosis of CBC depends on the first and second tumors.

Objective:To evaluate the efficacy of modular flexible ureteroscopy combined with minimally invasive percutaneous nephrolithotomy in patients with complex kidney stones.Methods:From March 2017 to February 2019 in Cangzhou Hospital of Integrated Traditional Chinese and Western Medicine, Hebei Province, 150 patients with complex kidney stones were selected. The patients were divided into group A, group B and group C by sortition method with 50 cases each. Group A was treated with modular flexible ureteroscopy, group B was treated with standard percutaneous nephrolithotomy, and group C was treated with modular flexible ureteroscopy combined with minimally invasive percutaneous nephrolithotomy. The operation time, transoperative bleeding, hospitalization time, calculi clearance 1- and 3-month after operation, procalcitonin (PCT) and C-reactive protein (CRP) 2 h before operation and 1 and 3 d after operation were compared among 3 groups.Results:The operation time, transoperative bleeding and hospitalization time in group C were significantly lower than those in group A and group B: (65.25 ± 7.90) min vs. (99.73 ± 8.52) and (96.11 ± 9.92) min, (33.22 ± 3.70) ml vs. (41.54 ± 3.62) and (45.17 ± 3.30) ml, (3.90 ± 0.90) d vs. (4.77 ± 1.17) and (5.70 ± 1.19) d, the calculi clearance 1- and 3-month after operation was significantly higher than that in group A and group B: 94.00% (47/50) vs. 80.00% (40/50) and 82.00% (41/50), 98.00% (49/50) vs. 84.00% (42/50) and 86.00% (43/50), and there were statistical differences ( P<0.05). There were no statistical differences in PCT and CRP 2 h before operation among 3 groups ( P>0.05); the PCT and CRP 1 and 3 d after operation in group C were significantly lower than those in group A and group B, and there were statistical differences ( P<0.05). There were no statistical differences in all indexes between group A and group B ( P>0.05). Conclusions:Modular flexible ureteroscopy combined with minimally invasive percutaneous nephrolithotomy can effectively improve calculi clearance, reduce surgical trauma, shorten operation time, promote recovery, and have significant therapeutic effects in the treatment of complex kidney stones.

Glass ionomer cement (GIC) is widely used as a common filling material in dentistry but still exhibits problems with secondary caries and fractures. Thus, the antibacterial and anti-caries performance of GIC needs to be further improved. In recent years, natural antimicrobial components have become more desirable due to their good biological properties and low drug resistance. In this review, the natural antimicrobial ingredients in GIC modification are classified, reviewed and summarized according to the different sources of antimicrobial ingredients. In terms of animal origin, chitosan and casein phosphopeptide-amorphous calcium phosphate exhibit antimicrobial properties without affecting the mechanical properties of materials; propolis and bioactive enzymes have good biocompatibility; in terms of plant origin, polyphenols help improve the antimicrobial and mechanical properties of the material; arginine has a good remineralization effect; and plant essential oils have a certain ion release effect. In terms of microbial origin, antibiotics greatly improve the antibacterial properties of materials; in addition, the combined application of natural antimicrobial ingredients also exhibited excellent performance. Despite these advantages, the optimal addition concentration and biocompatibility in vivo are questions that need to be further explored before clinical applications can be achieved.

Long non-coding RNAs (lncRNAs) regulate transcription to control development and homeostasis in a variety of tissues and organs. However, their roles in the development of the cerebral cortex have not been well elucidated. Here, a bioinformatics pipeline was applied to delineate the dynamic expression and potential cis-regulating effects of mouse lncRNAs using transcriptome data from 8 embryonic time points and sub-regions of the developing cerebral cortex. We further characterized a sense lncRNA, SenZfp536, which is transcribed downstream of and partially overlaps with the protein-coding gene Zfp536. Both SenZfp536 and Zfp536 were predominantly expressed in the proliferative zone of the developing cortex. Zfp536 was cis-regulated by SenZfp536, which facilitates looping between the promoter of Zfp536 and the genomic region that transcribes SenZfp536. Surprisingly, knocking down or activating the expression of SenZfp536 increased or compromised the proliferation of cortical neural progenitor cells (NPCs), respectively. Finally, overexpressing Zfp536 in cortical NPCs reversed the enhanced proliferation of cortical NPCs caused by SenZfp536 knockdown. The study deepens our understanding of how lncRNAs regulate the propagation of cortical NPCs through cis-regulatory mechanisms.

The standardized workflow of computer-aided static guided implant surgery includes preoperative examination, data acquisition, guide design, guide fabrication and surgery. Errors may occur at each step, leading to irreversible cumulative effects and thus impacting the accuracy of implant placement. However, clinicians tend to focus on factors causing errors in surgical operations, ignoring the possibility of irreversible errors in nonstandard guided surgery. Based on the clinical practice of domestic experts and research progress at home and abroad, this paper summarizes the sources of errors in guided implant surgery from the perspectives of preoperative inspection, data collection, guide designing and manufacturing and describes strategies to resolve errors so as to gain expert consensus. Consensus recommendation: 1. Preoperative considerations: the appropriate implant guide type should be selected according to the patient's oral condition before surgery, and a retaining screw-assisted support guide should be selected if necessary. 2. Data acquisition should be standardized as much as possible, including beam CT and extraoral scanning. CBCT performed with the patient’s head fixed and with a small field of view is recommended. For patients with metal prostheses inside the mouth, a registration marker guide should be used, and the ambient temperature and light of the external oral scanner should be reasonably controlled. 3. Optimization of computer-aided design: it is recommended to select a handle-guided planting system and a closed metal sleeve and to register images by overlapping markers. Properly designing the retaining screws, extending the support structure of the guide plate and increasing the length of the guide section are methods to feasibly reduce the incidence of surgical errors. 4. Improving computer-aided production: it is also crucial to set the best printing parameters according to different printing technologies and to choose the most appropriate postprocessing procedures.
