Abstract
Novel experimental techniques are required to make the next big leap in neutron electric dipole moment experimental sensitivity, both in terms of statistics and systematic error control. The nEDM experiment at the Spallation Neutron Source (nEDM@SNS) will implement the scheme of Golub & Lamoreaux [Phys. Rep., 237, 1 (1994)]. The unique properties of combining polarized ultracold neutrons, polarized 3He, and superfluid 4He will be exploited to provide a sensitivity to ∼ 10−28 e · cm. Our cryogenic apparatus will deploy two small (3 L) measurement cells with a high density of ultracold neutrons produced and spin analyzed in situ. The electric field strength, precession time, magnetic shielding, and detected UCN number will all be enhanced compared to previous room temperature Ramsey measurements. Our 3He co-magnetometer offers unique control of systematic effects, in particular the Bloch-Siegert induced false EDM. Furthermore, there will be two distinct measurement modes: free precession and dressed spin. This will provide an important self-check of our results. Following five years of “critical component demonstration,” our collaboration transitioned to a “large scale integration” phase in 2018. An overview of our measurement techniques, experimental design, and brief updates are described in these proceedings.

Abstract
AIMS Ratoon stunting disease caused by Leifsonia xyli subsp. xyli (Lxx) is a bacterial disease that has plagued sugarcane-planting countries for a long time. This study mainly analysed Lxx localization and its effects on sugarcane leaf. METHODS AND RESULTS Badila were inocultated by bacteria of Lxx. It was noted that the number of Lxx cells were rapidly enriched in sugarcane leaves from the 150th to the 210th days of post inoculation (dpi). Lxx infection disrupted the integrity of vascular bundle sheath cells (BSC) in the 'Kranz anatomy' of leaves, resulting in irregular accumulation of starch in vascular BSC of leaves. In situ PCR showed that the Lxx localized in the xylem vessels, mesophyll cell (MC) and BSC as described before in sugarcane leaf, a new niche within the host tissues in the phloem of sugarcane stem. The gene expression and activities of phosphoenolpyruvate carboxylase (PEPC), pyruvate, orthophosphate dikinase (PPDK) and NADP-malic enzyme (NADP-ME) enzymes were lower in Lxx-inoculated sugarcane plants as compared to the MI group. CONCLUSION Lxx infection not only disrupted the structure of vascular BSC in the C4 'Kranz anatomy' of sugarcane leaves, but also affected the activities and gene expression of the key enzymes PEPC, PPDK and NADP-ME in the C4 cycle of sugarcane suggesting a reduction in CO2 fixation. SIGNIFICANCE AND IMPACT OF THE STUDY The effect of Leifsonia xyli subsp. xyli (Lxx) infection on the photosynthetic physiology of sugarcane is currently limited to the evaluation of photosynthetic parameters. This study assessed the impact of Lxx infection on the mechanism of C4 cycle CO2 fixation and to accompanying plant anatomy.

Abstract
INTRODUCTION Chronic Myeloid Leukaemia (CML) constitutes 15% of new adult leukaemia cases as well as 2%-3% of leukaemia in children under 15% and 9% of leukaemias in adolescents 15-19 years of age annually. The introduction of Tyrosine Kinase Inhibitors (TKI) therapy has dramatically improved survival in these patients, yet the off-target effects of this treatment may have long-term health impacts on CML survivors. The risk of adverse health outcomes is especially important in children, where TKI exposure may occur during critical windows of growth and puberty, and patients require treatment for prolonged periods of time. The aim of this systematic review protocol is to report on the methods used to conduct a systematic review to investigate the endometabolic and bone health effects of TKI therapy in CML. METHODS AND ANALYSIS Searches will be conducted in the Cochrane Central Register of Controlled Trials, EMBASE and MEDLINE from inception on August 1st, 2019. Searches may be updated while performing the systematic review to ensure new evidence is included if applicable. Grey literature search will include ClinicalTrials.gov and ProQuest Dissertations and Theses A&I. We will perform a meta-analysis if there are at least two studies reporting similar populations, interventions, methods and tracking the same outcome measures. The studies should also have similar age and sex distributions. ETHICS AND DISSEMINATION As this is a systematic review protocol, it does not include patient data; therefore, Research Ethics Board approval is not indicated. The systematic review will be published in a peer-reviewed journal and presented at international conferences. PROSPERO REGISTRATION NUMBER CRD42018091175.

Abstract
PURPOSE Vitamin D is implicated linked to liver cancer and chronic liver diseases, but its association with tumor response in hepatocellular carcinoma (HCC) patients undergoing transarterial chemoembolization (TACE) remains unclear. This study aimed to determine whether vitamin D levels influence tumor response in HCC patients treated with TACE. METHODS A total of 58 HCC patients undergoing TACE were enrolled in the study. Serum 25-hydroxyvitamin D (25-OHD) levels were determined at baseline and 1 day after TACE using electrochemiluminescence immunoassay. Response to TACE was evaluated after a 4-6 week interval. Univariate and multivariate analyses with Cox regression model were performed to determine the risk factors associated with tumor response. Receiver operating characteristic (ROC) curve analysis was performed to assess the predictive performance of baseline 25-OHD levels on tumor response in HCC patients undergoing TACE. RESULTS 43.1% of HCC patients showed 25-OHD deficiency. Baseline 25-OHD level was associated with liver cirrhosis (P = 0.025), vascular invasion (P = 0.031), Barcelona Clinic Liver Cancer stage (P = 0.002) and an alanine aminotransferase increase after TACE (P = 0.021). Serum 25-OHD level was significantly decreased 1 day after TACE (P = 0.045). Multiple tumor numbers (P = 0.034) and low baseline 25-OHD levels (P = 0.040) were independently correlated with poor tumor response after TACE. ROC curve analysis showed that baseline 25-OHD levels present better predictive performance for OR in those patients, compared with other current clinical test pointers. CONCLUSION Our study suggested that 25-OHD deficiency at baseline is a prognostic indicator for a poor tumor response in hepatocellular carcinoma treated with TACE.

Abstract
In sheep, increased expression of the follicle-stimulating hormone receptor (FSHR) in the ovary is a common feature of ewes that carry the prolific allele. In this study, we demonstrated that polymorphisms in the core promoter of the FSHR gene are associated with the reproductive performance of Hu sheep and are involved in the transcriptional activity of FSHR. An approximately 1.5-kb region of the 5' flanking sequence of the Hu sheep FSHR gene was isolated and characterized, and its core promoter was located in the 5' regulatory region, from nucleotides -580 to -342. Four variants (c.-518T>C, c.-466C>T, c.-414A>G and c.-365C>T) were detected in this region, and six genotypes and three haplotypes were found in the Hu sheep population (n = 245). An association analysis revealed that these polymorphisms are associated with the litter size of Hu ewes. Furthermore, a luciferase assay showed that the T-C-A-C- and C-T-G-T-type core promoters have higher transcriptional activity than does the T-C-G-C type. Notably, the putative binding site for the transcription factor Yin Yang 1 (YY1) was present at the A allele of nucleotide -414, but YY1 can significantly increase the transcriptional activity of the FSHR core promoter, which contains three different haplotypes. Taken together, our results establish that these variants might be involved in regulating the transcriptional activity of FSHR and litter size in Hu ewes and may provide a novel candidate marker for marker-assisted selection in sheep breeding.

Abstract
Objective To determine the effect of an antibody to vascular endothelial growth factor (VEGF) on bone blood flow, bone strength, and bone mass in the young adult mouse. Methods Ten-week-old male BALB/cJ mice were body weight-randomized into either a rodent anti-VEGF monoclonal antibody (anti-VEGF, B20-4.1.1; 5 mg/kg 2×/wk.; n = 12) group or a vehicle (VEH; n = 12) group. After 42 days, mice were evaluated for bone blood flow at the distal femur by 18F-NaF-PET/CT and then necropsied. Samples from trabecular and cortical bone regions were evaluated for bone strength by mechanical testing, bone mass by peripheral quantitative computed tomography (pQCT), and micoarchitecture (MicroCT). Hydration of the whole femur was studied by proton nuclear magnetic resonance relaxometry (1H NMR). Results Distal femur blood flow was 43% lower in anti-VEGF mice than in VEH mice (p = 0.009). Ultimate load in the lumbar vertebral body was 25% lower in anti-VEGF than in VEH mice (p = 0.013). Bone mineral density (BMD) in the trabecular region of the proximal humeral metaphysis by pQCT, and bone volume fraction and volumetric BMD by MicroCT were the same in the two groups. Volume fraction of bound water (BW) of the whole femur was 14% lower in anti-VEGF than in VEH mice (p = 0.003). Finally, BW, but not cortical tissue mineral density, helped section modulus explain the variance in the ultimate moment experienced by the femur in three-point bending. Conclusion Anti-VEGF caused low bone blood flow and bone strength in trabecular bone regions without influencing BMD and microarchitecture. Low bone strength was also associated with low bone hydration. These data suggest that bone blood flow is a novel bone property that affects bone quality. An antibody to vascular endothelial growth factor (anti-VEGF) caused low bone blood flow in a trabecular bone rich region. Anti-VEGF did not affect trabecular bone region and bone hydration of the whole femur were also low, trabecular bone mass was not affected by anti-VEGF. Bone blood flow may be a bone property that affects bone quality through bone hydration. Anti-VEGF caused low trabecular bone strength in the vertebral body and low bone hydration of the whole femur.

Abstract
Objective: To compare the clinical efficacy of umbilical cord blood transplantation (UCBT) and hematopoietic stem cell transplantation from HLA-matched sibling donors (MSD-HSCT) in the treatment of myelodysplastic syndrome-EB (MDS-EB) or acute myeloid leukemia with myelodysplasia-related changes (AML-MRC) . Methods: A cohort of 64 patients (including 38 cases of MDS-EB and 26 cases of AML-MRC) who received UCBT/MSD-HSCT from February 2011 to December 2017 were retrospectively analyzed. Results: ①Compared with MSD-HSCT group, UCBT group had a higher proportion of AML-MRC patients [52.8% (19/36) vs 25.0% (7/28) , P=0.025], and a lower median age [13 (1.5-52) years vs 32 (10-57) years, P=0.001]. ②The engraftment of neutrophils both in UCBT and MSD-HSCT groups on +42 d was 100%, and the median engraftment time was 17.5 (11-31) d and 11.5 (10-20) d, respectively. The engraftment of platelet at +100 d in UCBT group was 91.4%, the median engraftment time was 40 (15-96) d; The engraftment of platelet at +100 d in MSD-HSCT group was 100%, and the median engraftment time was 15 (11-43) d. ③There were no statistically significant differences in terms of the cumulative incidence of Ⅱ-Ⅳ and Ⅲ/Ⅳ aGVHD of 100 d and transplant related mortality (TRM) of 180 d, relapse rate, overall survival (OS) , disease-free survival (DFS) between UCBT and MSD-HSCT groups (P>0.05) . ④The 3-year cumulative incidence of chronic GVHD (cGVHD) and severe chronic GVHD in UCBT group were lower than of MSD-HSCT group [28.3% (95%CI 13.4%-45.3%) vs 67.9% (95%CI 46.1%-82.4%) , P=0.002; 10.3% (95%CI 2.5%-24.8%) vs 50.0% (95%CI 30.0%-67.1%) , respectively, P<0.001]. The cumulative 3-year incidence of GVHD-free and relapse-free survival (GRFS) of UCBT group was significantly higher than of MSD-HSCT group [55.0% (95%CI 36.0%-70.6%) vs 28.6% (95%CI 13.5%-45.6%) , P=0.038]. Conclusion: UCBT could obtain better quality of life after transplantation than MSD-HSCT in treatment of MDS-EB/AML-MRC.

Abstract
OBJECTIVE To evaluate the efficacy and safety of submucosal tunneling endoscopic resection (STER) and endoscopic submucosal excavation (ESE) for upper gastroenterology submucosal tumors (SMT) originating from the muscularis propria (MP) layer. METHODS Clinicopathological and endoscopic data of 42 cases with upper gastroenterology tumors originating from the MP layer who were treated with STER (n=28) or ESE (n=14) between April 2013 and December 2016 in Peking University Third Hospital were retrospectively analyzed. The treatment and complications of the two groups were compared. RESULTS In the study, 42 cases were all resected by therapeutic endoscopy successfully.There was no significant difference (STER vs. ESE) in gender, age, mean tumor size [1.5 (1.0-6.0) cm vs. 1.3 (0.5-2.0) cm, P=0.056]. STER was superior to ESE with reduced sutured time [3.5 (1.0-11.0) min vs. 8.0 (2.0-33.0) min, P=0.006], but more resection time [46.5 (11.0-163.0) min vs.19.5 (6.0-56.0) min, P=0.007]. There was statistical difference between the two groups in resection time or sutured time, but no significant difference (STER vs. ESE) in total operative time [52.0 (14.0-167.0) min vs. 31.5 (10.0-88.0) min, P=0.080]. En bloc resection rates (92.9% vs. 85.7%), hospital stay duration and complications (10.7 vs. 0.0) were similar in the STER and ESE groups. One case developed mediastinal emphysema and 2 pneumonia after operation in STER group, and all of them recovered uneventfully after conservative treatments; There were no complications in the ESE group. After operation, 28 cases of leiomyoma and 14 cases of stromal tumor were diagnosed by routine pathological and immunohistochemical staining. Among them, 6 cases of stromal tumors in group STER were all extremely low risk, 4 cases of stromal tumors in group ESE were extremely low risk, 4 cases of stromal tumors in group ESE were medium risk (the size of the lesion was about 1.0-2.0 cm, and mitotic figures counted (6-8)/50 high power field). The median follow-up time of all the patients was 46.5 (24-60) months, and the shortest follow-up time for medium risk stromal tumors was 32 months. No residual tumor, recurrence and implantation in the tunnel were observed. CONCLUSION STER or ESE can be used as an effective and safe option for treatment of submucosal tumors originating from the muscularis propria of the upper digestive tract. Compared with STER, ESE had shorter resection time but longer wound closure time. There was no significant difference in total operation time.

Abstract
The centromere is an evolutionarily conserved eukaryotic protein machinery essential for precision segregation of the parental genome into two daughter cells during mitosis. Centromere protein A (CENP-A) organizes the functional centromere via a constitutive centromere-associated network composing the CENP-T complex. However, how CENP-T assembles onto the centromere remains elusive. Here we show that CENP-T binds directly to Holliday junction recognition protein (HJURP), an evolutionarily conserved chaperone involved in loading CENP-A. The binding interface of HJURP was mapped to the C terminus of CENP-T. Depletion of HJURP by CRISPR-elicited knockout minimized recruitment of CENP-T to the centromere, indicating the importance of HJURP in CEPN-T loading. Our immunofluorescence analyses indicate that HJURP recruits CENP-T to the centromere in S/G2 phase during the cell division cycle. Significantly, the HJURP binding-deficient mutant CENP-T6L failed to locate to the centromere. Importantly, CENP-T insufficiency resulted in chromosome misalignment, in particular chromosomes 15 and 18. Taken together, these data define a novel molecular mechanism underlying the assembly of CENP-T onto the centromere by a temporally regulated HJURP-CENP-T interaction.

Abstract
Objective: To explore the effect of heme oxygenase-1 (HO-1) on level of reactive oxygen species (ROS) induced by zinc oxide nanoparticles (ZnO-NPs) in Human umbilical vein endothelial cells line EA.hy926. Methods: The EA.hy926 cells in logarithmic growth phase were incubated with 0.0, 2.5, 5.0, 10.0 and 15.0 mg/L ZnO-NPs respectively. The ROS level, reflected by mean fluorescence intensity (MFI), was examined by flow cytometer after 4 hours exposure, the protein expression of HO-1 which was determined by Western Blot after exposed to ZnO-NPs for 24 hours. Cells incubated with 15.0 mg/L were set as the ZnO-NPs group; a blank control group was set at the same time. Cells were pretreated with HO-1 inhibitor zinc protoporphyrin (ZnPPIx) and HO-1 activator cobalt protoporphyrin (CoPPIx), they were classified as ZnPPIx group and CoPPIx group. 15 mg/L ZnO-NPs was chosen to conduct the experiment of HO-1 activation and inhibition. Cells were classified as ZnPPIX+ ZnO-NPs group and CoPPIx+ ZnO-NPs group after pretreated with 10 μmol/L ZnPPIx or CoPPIx for 1 h, added 15 mg/L ZnO-NPs to cell culture medium. In all groups ROS levels were detected after exposed to ZnO-NPs for 4 hours, the protein expression of HO-1 was detected after exposed to ZnO-NPs for 24 hours. Results: With the increased dose of ZnO-NPs, levels of ROS and HO-1 in EA.hy926 cells were clearly elevated (the MFI of 0.0, 2.5, 5.0, 10.0 and 15.0 mg/L ZnO-NPs incubated groups was 22 627.22±718.27, 24 726.47±568.52, 31 141.75±1 312.24, 39 824.82±4 774.74, 50 569.03±1 497.63 respectively, and HO-1 relative expression were 0.16±0.01, 0.19±0.02, 0.16±0.01, 0.23±0.02, 0.92±0.06 respectively). HO-1 expression in ZnPPIx pretreatment group decreased compared with ZnO-NPs group (1.05±0.05 vs. 1.12±0.01, P<0.05), meanwhile ROS level enhanced (62 683.95±2 589.59 vs. 53 654.53±2 229.01, P<0.05). However, CoPPIx pretreatment had higher HO-1 level and lower level of ROS compared with ZnO-NPs group (HO-1: 1.74±0.11 vs. 0.22±0.03, P<0.05; ROS: 32 845.04±993.48 vs. 53 654.53±2 229.01, P<0.05). Conclusions: Exposure to ZnO-NPs significantly induced ROS generation in EA.hy926 cells in a dose-dependent manner. HO-1 regulated ZnO-NPs-induced oxidative stress.

Abstract
Background and Objectives Laser generated shockwave (LGS) is a novel modality for minimally invasive disruption of bacterial biofilms. The objectives of this study are to determine the mechanisms behind LGS treatment and non-biofilm effects on bacterial disruption, including (1) comparing bacterial load with and without LGS in its planktonic form and (2) estimating bacterial cell permeability following LGS. Study Design/Materials and Methods For the first study, planktonic S. epidermidis were treated with gentamicin (0, 8, 16, 32, 64 μg/ml) with and without LGS (1064 nm Nd:YAG laser, 110.14 mJ/mm2 , pulse duration 9 ns, spot size 3 mm, n = 8/group), and absorbances at 600 nm compared. For the second study, four samples of planktonic S. epidermidis were treated with LGS (same settings). Propidium iodide (PI) uptake via flow cytometry as a measure of cell permeability was measured at 0, 10, and 20 minutes following LGS. RESULTS: In comparing corresponding gentamicin concentrations within both LGS-treated samples and controls at 0 hours, there were no differences in absorbance (P = 0.923 and P = 0.814, respectively). Flow cytometry found modest PI uptake (10.4 ± 2.5%) immediately following LGS treatment, with time-dependent increase and persistence of the signal at 20 minutes (R2 = 0.449, P = 0.048). CONCLUSION: Taken together, LGS does not appear to have direct bacteriocidal properties, but rather by allowing for biofilm disruption and bacterial cell membrane permeabilization, both of which likely increase topical antibiotic delivery to pathogenic organisms. Insight into the mechanisms of LGS will allow for improved clinical applications and facilitate safe and effective translation of this technology. Lasers Surg. Med. © 2018 Wiley Periodicals, Inc.

Abstract
PURPOSE To invent, design, construct, and commission an intensity modulated minibeam proton therapy system (IMMPT) without the need for physical collimation and to compare its resulting conformity to a conventional IMPT system. METHODS A proton therapy system (Hitachi, Ltd, Hitachi City, Japan; Model: Probeat-V) was specially modified to produce scanned minibeams without collimation. We performed integral depth dose acquisitions and calibrations using a large diameter parallel-plate ionization chamber in a scanning water phantom (PTW, Freiburg, Germany; Models: Bragg Peak ionization chamber, MP3-P). Spot size and shape was measured using radiochromic film (Ashland Advanced Materials, Bridgewater NJ; Type: EBT3), and a synthetic diamond diode type scanned point by point in air (PTW Models: MicroDiamond, MP3-P). The measured data were used as inputs to generate a Monte Carlo-based model for a commercial radiotherapy planning system (TPS) (Varian Medical Systems, Inc., Palo Alto, CA; Model: Eclipse v13.7.15). The regular ProBeat-V system (sigma ~2.5 mm) TPS model was available for comparison. A simulated base of skull case with small and medium targets proximal to brainstem was planned for both systems and compared. RESULTS The spot sigma is determined to be 1.4 mm at 221 MeV at the isocenter and below 1 mm at proximal distances. Integral depth doses were indistinguishable from the standard spot commissioning data. The TPS fit the spot profiles closely, giving a residual error maximum of 2.5% in the spot penumbra tails (below 5% of maximum) from the commissioned energies 69.4 to 221.3 MeV. The resulting IMMPT plans were more conformal than the IMPT plans due to a sharper dose gradient (90-10%) 1.5 mm smaller for the small target, and 1.3 mm for the large target, at a representative central axial water equivalent depth of 7 cm. CONCLUSIONS We developed, implemented, and tested a new IMMPT system. The initial results look promising in cases where treatments can benefit from additional dose sparing to neighboring sensitive structures.

Abstract
Objective: To analyze satisfaction with follow-up management of HIV/AIDS cases conducted by Community Health Service Center (CHS) and related factors in Hongkou district, Shanghai. Methods: Out of 302 HIV/AIDS cases followed up by CHS in Hongkou district from 2012 to 2016, 263 HIV/AIDS cases were recruited to participate in a cross-sectional study assessed by self-designed questionnaire-based interview during October 1, 2016 and October 20, 2016, with efficiency of 87.1%. Information of basic characteristics including sociodemographic, routes of infection, CD4(+)T cell counts, diagnose of AIDS and status of receiving ART were collected, as well as satisfaction with follow-up management conducted by CHS including service professionalism, service attitude, service environment, referral service, privacy protection, health education, psychological support, and care and assistance. Factors related to satisfaction were analyzed using multiple binary logistic regression. Results: Among 263 HIV/AIDS cases, the average age was 42.0±13.5, 93.2% (245 cases) were male and the proportion of overall satisfaction was 72.2% (190 cases). Out of 8 items of satisfaction, service attitude and health education got the highest score with a total number of 235 (89.4%) answering "very satisfied" or "satisfied" , while care and assistance got the lowest score with a total number of 69 (26.2%) answering "dissatisfied" or "very dissatisfied" . Compared to HIV/AIDS local residents and followed up by CHS <12 months, those who were non-local residents and followed up by CHS ≥12 months were more likely to be satisfied, the OR (95%CI) were 2.66 (1.30-5.44) and 2.52 (1.01-6.29), respectively. Compared to HIV/AIDS ≤30 years old and receiving ART, those who were 31-50 years or >50 years old and not receiving ART were less likely to be satisfied, the OR (95%CI) were 0.36 (0.15-0.89), 0.32 (0.10-0.97) and 0.11 (0.01-0.90), respectively. Conclusion: Satisfaction with follow-up management conducted by CHS in Hongkou district is relatively high. Age, residence, status of receiving ART and cumulative time of following up by CHS are significantly associated with satisfaction, suggesting that CHS should improve their professional abilities during follow-up management, as well as be more targeted and focus on different aspects.

Abstract
UNLABELLED We designed a study to compare the efficacy of five main therapeutic options, including external fixation, open reduction and plate osteosynthesis (ORPO), minimally invasive plate osteosynthesis (MIPO), dynamic compression plate (DCP), and intramedullary nail (IMN) in treating humeral shaft fractures. Our results indicated that MIPO and IMN were recommended as the optimal treatments for clinical use. PURPOSE Nowadays, five main therapeutic options are used in treating humeral shaft fractures: external fixation, open reduction and plate osteosynthesis (ORPO), minimally invasive plate osteosynthesis (MIPO), dynamic compression plate (DCP), and intramedullary nail (IMN). Aiming to provide reliable evidence for clinical selection, we designed a network meta-analysis (NMA) to evaluate the efficacy of these treatments. METHODS NMA was conducted on Bayesian framework with software R 3.3.2 and STATA 13.0. Nonunion rate, radial nerve palsy rate, union time, complication rate, and infection rate were considered as primary outcomes. Mean operation time was the secondary outcome. The outcomes were measured by odds ratio (OR) value and corresponding 95% credible intervals (CrIs) or mean difference (MD) with 95% CrIs. Surface under cumulative ranking curve (SUCRA) was calculated to show the ranking probability of each treatment. RESULTS Our results indicated that ORPO had a higher risk of radial nerve palsy than MIPO (OR = 2.83, 95% CrIs = 1.28-6.23), and DCP had a better performance in preventing complications than IMN (OR = 0.31, 95% CrIs = 0.11-0.84); no other significant difference were observed. According to the SUCRA results, MIPO had a high-ranking probability in almost all outcomes, while external fixation had lowest values in the majority of outcomes. CONCLUSIONS We recommended MIPO as the optimal treatment for humeral shaft fractures after taking all outcomes into consideration; IMN was also recommended for its relatively good performance, but its complication still needed to be noticed.
