Objective To explore the clinical effectiveness of a locally trained and re-optimized RapidPlan model in lung stereotactic body radiation therapy (SBRT). Methods A total of 132 lung SBRT cases were retrospectively collected as a training group for the establishment of an initial RapidPlan model (RP-1) in the Eclipse 15.5 treatment planning system. RP-1 was then used to optimize the training group plans to generate the first-generation RapidPlans, which were used as a new training group to generate the upgraded RapidPlan model (RP-Plus). Additional 40 lung SBRT cases were selected to verify the quality and efficiency of RP-Plus plans, which were further assessed through clinical quality assurance (QA). Results The RP-Plus reduced the average number of optimization cycles by 2.1 times and 0.3 times compared to manual and RP-1 methods, respectively, and reduced the optimization time by 57.6% and 18.8%. The conformity index met clinical requirements, and the gradient index and Max2cm(%) were improved compared to RP-1 (both P < 0.05). The RP-Plus plans showed lower dosimetric parameters of organs at risk, including lung V20Gy, spinal cord Dmax, and heart

Objective:To investigate the causality between intestinal flora and hypertrophic scars (HS) of human.Methods:This study was a study based on two-sample Mendelian randomization (TSMR) analysis. The data on intestinal flora ( n=18 473) and HS ( n=208 248) of human were obtained from the genome-wide association study database. Genetically variable genes at five levels (phylum, class, order, family, and genus) of known intestinal flora, i.e., single nucleotide polymorphisms (SNPs), were extracted as instrumental variables for linkage disequilibrium (LD) analysis. Human genotype-phenotype association analysis was performed using PhenoScanner V2 database to exclude SNPs unrelated to HS in intestinal flora and analyze whether the selected SNPs were weak instrumental variables. The causal relationship between intestinal flora SNPs and HS was analyzed through four methods of TSMR analysis, namely inverse variance weighted (IVW), MR-Egger regression, weighted median, and weighted mode. Scatter plots of significant results from the four aforementioned analysis methods were plotted to analyze the correlation between intestinal flora SNPs and HS. Both IVW test and MR-Egger regression test were used to assess the heterogeneity of intestinal flora SNPs, MR-Egger regression test and MR-PRESSO outlier test were used to assess the horizontal multiplicity of intestinal flora SNPs, and leave-one-out sensitivity analysis was used to determine whether HS was caused by a single SNP in the intestinal flora. Reverse TSMR analyses were performed for HS SNPs and genus Intestinimonas or genus Ruminococcus2, respectively, to detect whether there was reverse causality between them. Results:A total of 196 known intestinal flora, belonging to 9 phyla, 16 classes, 20 orders, 32 families, and 119 genera, were obtained, and multiple SNPs were obtained from each flora as instrumental variables. LD analysis showed that the SNPs of the intestinal flora were consistent with the hypothesis that genetic variation was strongly associated with exposure factors, except for rs1000888, rs12566247, and rs994794. Human genotype-phenotype association analysis showed that none of the selected SNPs after LD analysis was excluded and there were no weak instrumental variables. IVW, MR-Egger regression, weighted median, and weighted mode of TSMR analysis showed that both genus Intestinimonas and genus Ruminococcus2 were causally associated with HS. Among them, forest plots of IVW and MR-Egger regression analyses also showed that 16 SNPs (the same SNPs number of this genus below) of genus Intestinimonas and 15 SNPs (the same SNPs number of this genus below) of genus Ruminococcus2 were protective factors for HS. Further, IVW analysis showed that genus Intestinimonas SNPs (with odds ratio of 0.62, 95% confidence interval of 0.41-0.93, P<0.05) and genus Ruminococcus2 SNPs (with odds ratio of 0.62, 95% confidence interval of 0.40-0.97, P<0.05) were negatively correlated with the risk of HS. Scatter plots showed that SNPs of genus Intestinimonas and genus Ruminococcus2 were protective factors of HS. Both IVW test and MR-Egger regression test showed that SNPs of genus Intestinimonas (with Q values of 5.73 and 5.76, respectively, P>0.05) and genus Ruminococcus2 (with Q values of 13.67 and 15.61, respectively, P>0.05) were not heterogeneous. MR-Egger regression test showed that the SNPs of genus Intestinimonas and genus Ruminococcus2 had no horizontal multiplicity (with intercepts of 0.01 and 0.06, respectively, P>0.05); MR-PRESSO outlier test showed that the SNPs of genus Intestinimonas and genus Ruminococcus2 had no horizontal multiplicity ( P>0.05). Leave-one-out sensitivity analysis showed that no single intestinal flora SNP drove the occurrence of HS. Reverse TSMR analysis showed no reverse causality between HS SNPs and genus Intestinimonas or genus Ruminococcus2 (with odds ratios of 1.01 and 0.99, respectively, 95% confidence intervals of 0.97-1.06 and 0.96-1.04, respectively, P>0.05). Conclusions:There is a causal relationship between intestinal flora and HS of human, in which genus Intestinimonas and genus Ruminococcus2 have a certain effect on inhibiting HS.

Objective:To investigate the effects and mechanism of baicalin on the wound healing of full-thickness skin defects in diabetic mice.Methods:This study was an experimental research. Mononuclear cells were isolated from five male C57BL/6J mice aged 8-12 weeks and induced to differentiate into macrophages for conducting the subsequent experiments. According to the random number table (the same grouping method below), macrophages in a high-glucose environment were divided into 0 μmol/L baicalin group (no baicalin was added), 5 μmol/L baicalin group, 15 μmol/L baicalin group, 25 μmol/L baicalin group, 50 μmol/L baicalin group, and 75 μmol/L baicalin group treated with the corresponding final molarity of baicalin and 1 μg/mL endotoxin/lipopolysaccharide (LPS). After treatment for 48 hours, the cell proliferation activity was detected using a microplate reader. Macrophages in a high-glucose environment were divided into LPS group treated with 1 μg/mL LPS and LPS+baicalin group treated with 50 μmol/L baicalin+1 μg/mL LPS. After treatment for 48 hours, the percentage of double-positive cells for inducible nitric oxide synthase (iNOS) and CD80, as well as that for arginase 1 (Arg1) and CD206 among the cells, were detected using immunofluorescence method, the secretion levels of interleukin 1β (IL-1β), IL-6, IL-23, IL-10, insulin-like growth factor (IGF), and transforming growth factor β 1 (TGF-β 1) by the cells were detected using enzyme-linked immunosorbent assay, the expression of reactive oxygen species in the cells was detected using a fluorescent probe method, the protein expression of nuclear factor κB in the cells were detected using Western blotting, and the expression of nuclear factor 2 in the cells was observed using immunofluorescence method. The number of cell experimental samples was 3. Twenty-four 8-week-old male db/db mice were selected. After preparing full-thickness skin defect wounds on their backs, they were divided into baicalin group and normal saline group (with 12 mice in each group). On the third day after injury, 50 μmol/L baicalin and normal saline were injected into the wounds of mice, respectively. The wound healing situation was observed and the percentage of the residual wound area was calculated on the 4 th, 8 th, and 12 th day after injury. The wound tissue was sampled on the 8 th day after injury, hematoxylin-eosin staining was performed to observe the epithelial regeneration and inflammatory cell infiltration, the protein expression of CD31 was detected by Western blotting, and the expression of reactive oxygen species was detected by a microplate reader. The number of animal experimental samples was 6. Results:After treatment for 48 hours, only the proliferation activity of macrophages in 50 μmol/L baicalin group was significantly higher than that in 0 μmol/L baicalin group ( P<0.05). After treatment for 48 hours, the percentage of double-positive cells for iNOS and CD80 among the macrophages in LPS+baicalin group was (21.0±2.4)%, which was significantly lower than (66.6±4.5)% in LPS group ( t=15.63, P<0.05); the percentage of double-positive cells for Arg1 and CD206 among the macrophages in LPS+baicalin group was (59.1±2.1)%, which was significantly higher than (18.6±1.7)% in LPS group ( t=25.38, P<0.05); compared with those in LPS group, the secretion levels of IL-1β, IL-6, and IL-23 by the macrophages in LPS+baicalin group were significantly decreased (with t values of 14.26, 15.95, and 12.23, respectively, P<0.05), while the secretion levels of IL-10, IGF, and TGF-β 1 were significantly increased (with t values of 8.49, 11.98, and 13.84, respectively, P<0.05); the expression of reactive oxygen species in the macrophages in LPS+baicalin group was significantly lower than that in LPS group ( t=5.54, P<0.05); compared with those in LPS group, the protein expression of nuclear factor κB in the nucleus of the macrophages in LPS+baicalin group was significantly decreased ( t=36.22, P<0.05), while that in the cytoplasm was significantly increased ( t=14.47, P<0.05), and the expression of nuclear factor 2 in the nucleus was increased. On the 4 th and 8 th day after injury, the wound area of mice in baicalin group was significantly smaller than that in normal saline group, and the wounds of mice in baicalin group completely healed on the 12 th day after injury. On the 4 th, 8 th, and 12 th day after injury, the residual wound area percentage of mice in baicalin group was significantly lower than that in normal saline group (with t values of 13.29, 10.08, and 11.72, respectively, P<0.05). On the 8 th day after injury, compared with those in normal saline group, the wound tissue of mice in baicalin group showed significant re-epithelization, the infiltration of inflammatory cells was reduced, the expression of CD31 protein was significantly increased ( t=17.23, P<0.05), and the expression of reactive oxygen species was significantly reduced ( t=5.78, P<0.05). Conclusions:Baicalin alleviates the inflammatory response of macrophages by lowering the level of reactive oxygen species in cells and promoting the polarization of macrophages to the M2 type, thereby facilitating the healing of full-thickness skin defect wounds in diabetic mice.
