Objective:To analyze the survival and prognostic factors of adult acute lymphoblastic leukemia (ALL) with different consolidation regimens after complete remission by induction therapy.Methods:A total of 93 adult patients with ALL were enrolled from January 2012 to June 2019 in Peking University Shenzhen Hospital. All the patients achieved complete remission induced by VDLCP regimen, and were divided into the standard group, intensive group and transplantation group according to the consolidation treatment. Thirty-four patients in the standard group received an ALL-like chemotherapy regimen based on VDLCP or Hyper-CVAD consolidation for 4-6 courses. Twenty-nine patients in the intensive group received BFM90/95 consolidation treatment for 2 years. Thirty patients in the transplantation group received allogeneic hematopoietic stem cell transplantation (allo-HSCT) after 2-3 courses of consolidation with the original induction regimen. The median follow-up was 18 (3-96) months, and the main follow-up indicators were overall survival (OS) and disease free survival (DFS). Prognostic factors of adult ALL patients and treatment-related deaths in each group were analyzed.Results:The 3-year OS rates of the standard group, intensive group and transplantation group were 54.0% (95% CI: 35.3%-72.6%), 71.8% (95% CI: 41.0%-94.5%), 62.3% (95% CI: 43.6%-80.9%), with a statistically significant difference ( χ2=6.110, P=0.047). The 3-year DFS rates of the three groups were 31.4% (95% CI: 12.9%-49.8%), 72.1% (95% CI: 52.3%-91.9%), 65.7% (95% CI: 45.3%-86.1%), with a statistically significant difference ( χ2=13.831, P=0.001). There were no significant differences in OS and DFS between the intensive group and the transplantation group ( χ2=0.709, P=0.400; χ2=0.046, P=0.830). OS and DFS of the intensive group were better than those of the standard group ( χ2=5.346, P=0.021; χ2=10.326, P=0.010). Multivariate analysis suggested that bone marrow minimal residual disease (MRD) negative on day 14-21 of chemotherapy was an independent prognostic factor affecting adult ALL ( HR=0.114, 95% CI: 0.015-0.841, P=0.033). The 3-year OS rates of Ph + ALL patients who received and did not receive allo-HSCT were 53.5% (95% CI: 23.1%-83.8%), 52.4% (95% CI: 23.8%-81.0%), the 3-year DFS rates were 77.1% (95% CI: 54.2%-100.0%), 35.0% (95% CI: 4.8%-65.2%), and there were no significant differences between the two groups ( χ2=3.600, P=0.223; χ2=3.824, P=0.050). The treatment-related mortalities of the non-transplantation group (standard group + intensive group) and the transplantation group were 3.2% (2/63) and 20.0% (6/30), and the treatment-related mortality of the non-transplantation group was significantly lower than that of the transplantation group ( χ2=7.318, P=0.007). Conclusion:Adult ALL has a poor prognosis. The 3-year OS rate and 3-year DFS rate of BFM intensive consolidation therapy are better than those of standard consolidation therapy, achieving a similar effect to allo-HSCT, but treatment-related mortality does not increase significantly. Patients with bone marrow MRD negative on the day 14-21 of chemotherapy have the better OS and DFS.

Digital technology is a new trend in implant dentistry and oral medical technology. Stereolithographic surgical guides, which are computer-guided implant placement, have been introduced gradually to the market. Surgeons are attracted to this approach because of it features visualized preoperative planning, simple surgical procedure, flapless implant, and immediate restoration. However, surgeons are concerned about the accuracy and complications of this approach. This review aims to introduce the classification of computer-guided implant placement. The advantages, disadvantages, and accuracy of this approach are also analyzed. Moreover, factors that may affect the outcomes of computer-guided implant placement are determined. Results will provide a reference to surgeons regarding the clinical application of this approach.

Objective: To explore the clinical efficacy and imaging changes of minimally invasive nonsurgical periodontal therapy (MINST) assisted by endoscopy for deep intrabony defects and to compare its effectiveness with that of traditional scaling and root planning (SRP) to therefore provide a reference for clinical periodontal treatment. Methods: Patients with deep intrabony defects ≥ 4 mm in size were selected and divided into two groups: the MINST (MINST, 20 cases, 81 sites) group and the classic scaling and root planing (SRP, 20 cases, 80 sites) group. Before treatment and 12 and 24 months after treatment, probing depth (PD) and clinical attachment loss (CAL) were examined. Moreover, changes in the depth and angle of the intrabony defects were analyzed. Follow-up examination and maintenance treatment should be conducted every 3 months for 12 months after the initial treatment and every 6 months thereafter until 24 months. Results: The PD and CAL of patients in both groups continued to decrease (P<0.001), and imaging examinations revealed a decrease in defect depth and an increase in intrabony defect angle (P<0.001). The changes in the first 12 months were significantly greater than those in the last 12 months in both groups (P<0.001). The decreases in PD, CAL, and depth of intrabony defects and increase in angle in the MINST group were significantly greater than those in the SRP group (P<0.001). At 12 and 24 months after treatment, the PD and CAL in the MINST group were lower than those in the SRP group (P<0.001). The defect height of the MINST group decreased more than that of the SRP group (P<0.001), and the defect angle of the MINST group increased more than that of the SRP group (P<0.001). Conclusion Minimally invasive nonsurgical periodontal therapy can significantly promote the healing of deep intrabony defects and the regeneration of alveolar bone. Imaging reflects that alveolar bone healing is rapid at first and then slows. Compared with traditional SRP, endoscopically assisted MINST can yield better clinical indicators and imaging changes in intrabony defects.

Objective:To explore the effect of Toll-like receptor 9 (TLR9) signaling pathway activation on the transcriptome in the renal tubular cells.Methods:Mouse primary renal tubular epithelial cells were extracted and cultured. When the degree of cell fusion reached 80%, they were divided into two groups, which were added with 10 μL phosphate buffered saline (PBS, PBS control group) and TLR9 activator cytosine phosphate guanidine oligodeoxynucleotide (CpG-ODN) with a final concentration of 5 μmol/L (CpG-ODN treatment group). The RNA sequencing was performed on the Illumina platform after extraction. DEGseq software was used to analyze the differential expression of genes between the two groups. Goatools and KOBAS online software were used to analyze the differential genes involved signal pathways. Homer software was used to predict transcription factors.Results:Compared with the PBS control group, there were a total of 584 differentially expressed genes in the CpG-ODN treatment group, of which 102 were up-regulated and 482 were down-regulated. The most significantly enriched gene ontology (GO) terms of differentially expressed genes included response to interferon-β, defense response to virus and other inflammatory pathway. The most significantly enriched Kyoto Encyclopedia of Genes and Genomes (KEGG) signaling pathways included 2'-5'-oligoadenylate synthase activity, regulation of ribonuclease activity, negative regulation of virus life cycle, cellular response to interferon-βand defense response to protozoan. The results of transcription factor prediction showed that interferon regulatory factor 3 (IRF3) was the most significantly enriched transcription factor in the promoter sequence of differential genes; the most significant transcription factor downstream of TLR9 was IRF3, and other predicted transcription factors such as transcription factor 21 (TCF21), zinc finger protein 135 (ZNF135), and PR domain containing 4 (PRDM4) might be new candidates for TLR9 signaling pathway.Conclusion:CpG-ODN activates TLR9 signaling pathway, and primary renal tubular epithelial cells can directly respond to CpG-ODN stimulation and undergo transcriptome changes, which provides a basis for further research on the molecular mechanism of TLR9 pathway in sepsis induced acute kidney injury.
