Abstract
BACKGROUND Previous studies have demonstrated that pure transanal endoscopic surgery is safe and feasible in the treatment of rectal cancer. However, the role of pure transanal endoscopic colectomy in ascending colon cancer (ACC) treatment has not been evaluated. We report a case of transanal endoscopic surgery for ACC. METHODS A 35-year-old woman was treated for ACC, using a transanal endoscopic surgery device as the operation platform, and pure transanal endoscopic right hemicolectomy without transabdominal assistance was safely performed. An instrument suture, side-to-side, ileocolic anastomosis was performed. Operative time was 245 min and intraoperative blood loss was 60 ml. RESULTS The patient recovered well from the surgery. Compared with the traditional approach, this approach was less invasive and resulted in satisfactory outcomes and cosmesis (no scar). CONCLUSIONS Application of pure transanal endoscopic colectomy without abdominal assistance to ACC appears to be feasible and safe.

Abstract
Surgery for rectal cancer has obtained quick improvement in techniques and concepts in recent years but still has challenging areas. Colorectal surgeons always seek to make operations clearer and easier, so that surgery can be safer and less time-consuming while guaranteeing surgical goals. With this purpose, our team have explored to make innovations in operations for rectal cancer and translate relevant patents from 2009. We summarize our achievements in this article as follows: (1) Reverse Miles operation (perineal operation first then laparoscopic abdominal operation) with two relevant patents-specialized instruments bag for laparoscopic operations (patent number ZL201520442331.0) and accessory spotlight for ultrasound scalpel (patent number ZL20102 0137689.X). (2) Laparoscopic sphincter-saving surgery for low rectal cancer through marker meeting approach with two patents-vacuum rectal drainage tube with functions of irrigation and ventilation (patent number ZL201520374385.8) and sterile sleeve cover of ultrasound scalpel handle (patent number ZL201920648102.2). (3) Laparoscopic radical resection of colorectal cancer and natural orifice specimen extraction. Different methods were designed according to the location of the tumor that classified as 20-40 cm, 10-20 cm and 5-10 cm to anus. Two relevant patents were specialized instruments for natural orifice specimen extraction (patent application number ZL2017101480141) and plastic film sleeve for natural orifice specimen extraction (patent application number ZL 201921169857.0). Reformation of surgical technique and innovation of surgical instruments should be conducted by surgeons with innovative thinking who always seek the way to translate ideas to patents and then real products to promote surgical treatment.

Abstract
Background Health-care professionals need to collect wound samples to identify potential pathogens that contribute to wound infection. Obtaining appropriate samples from diabetic foot ulcers (DFUs) where there is a suspicion of infection is of high importance. Paired swabs and tissue biopsies were collected from DFUs and both sampling techniques were compared using 16S rRNA gene sequencing. Results Mean bacterial abundance determined using quantitative polymerase chain reaction (qPCR) was significantly lower in tissue biopsies (p = 0.03). The mean number of reads across all samples was significantly higher in wound swabs \documentclass[12pt]{minimal}

However, based on a presence/absence analysis of all paired samples, the frequency of occurrence of bacteria from genera of known and potential pathogens was generally higher in wound swabs than tissue biopsies. Multivariate analysis identified significantly different bacterial communities in swabs compared to tissue (p = 0.001). There was minimal correlation between paired wound swabs and tissue biopsies in the number and types of microorganisms. RELATE analysis revealed low concordance between paired DFU swab and tissue biopsy samples (Rho = 0.043, p = 0.34). Conclusions Using 16S rRNA gene sequencing this study identifies the potential for using less invasive swabs to recover high relative abundances of known and potential pathogen genera from DFUs when compared to the gold standard collection method of tissue biopsy.

Abstract
Background:In the FINCH 1 study, filgotinib (FIL)—an oral, potent, selective Janus kinase 1 inhibitor—in combination with methotrexate (MTX) provided significant improvements in the signs and symptoms of rheumatoid arthritis (RA) in patients (pts) with inadequate response to MTX.1While EULAR guidelines recommend a treat-to-target approach focusing on reducing inflammation to prevent joint damage, physical disability, and mortality, pts consider control of pain and fatigue, along with maintenance of physical function and health-related quality of life (HRQoL), to be important aspects for their care.2,3Objectives:To evaluate the rate and magnitude of change in patient-reported outcomes (PROs) from FINCH 1.Methods:In the FINCH 1 study (NCT02889796), pts with active RA received oral FIL 200 mg + MTX, FIL 100 mg + MTX, PBO + MTX, or subcutaneous adalimumab (ADA) 40 mg + MTX for up to 52 weeks (W); pts receiving PBO at W24 were rerandomised 1:1 to FIL 100 or 200 mg. PROs included the HAQ-DI and VAS pain scale, SF-36, and FACIT-Fatigue questionnaire. The change from baseline (CFB) at each time point was assessed up to W52 for each treatment group. The mixed-effects model for repeated measures was used to compare each FIL group with PBO for the CFB at each time point through W24. The logistic regression model was used to compare each FIL group with PBO for the proportion of pts achieving the minimum clinically important difference (MCID) of ≥0.22 reduction in CFB in HAQ-DI at each time point through W24.Results:Of 1755 pts randomised and treated (475 FIL 200 mg + MTX; 480 FIL 100 mg + MTX; 325 ADA + MTX; and 475 PBO + MTX), 1417 (80.7%) received study drug through W52. As early as W2 through W24, pts receiving either dose of FIL experienced nominally significantly greater (p <0.001) CFB in HAQ-DI and VAS pain scale than those receiving PBO; CFB improvements were maintained through W52 (Fig 1A, B). At W2, compared with PBO (40.2%), a nominally significantly greater proportion of pts achieved the HAQ-DI MCID in both the FIL 200 (52.5%; p <0.001) and 100 mg (46.7%; p = 0.043) groups. This benefit vs PBO was maintained up to W24 and the proportion of pts who achieved a HAQ-DI reduction of ≥0.22 remained ≥75.8% in the FIL 200 mg group and ≥71.5% in the FIL 100 mg group from W12 through W52. FIL provided nominally significantly greater improvement in HRQoL vs PBO at W4 and W12 for both the CFB of the SF-36 Physical Component Summary (PCS) (p <0.001) and Mental Component Summary (MCS) (p ≤0.006); nominal significance was also seen at W24 for CFB of SF-36 PCS (Fig 2A, B). By W4, pts receiving either dose of FIL reported a nominally significantly greater mean CFB in FACIT-Fatigue scores vs PBO (p <0.001); significance was maintained through W24 and improvement in reported fatigue continued through W52 in the FIL groups (Fig 2C). In general, CFB for HAQ-DI, VAS pain scale, and FACIT-Fatigue observed for the FIL groups was higher or comparable to ADA at various time points (Fig 1, 2).Conclusion:Both doses of FIL provided rapid and sustained improvements in functional status, pain, HRQoL, and fatigue compared with PBO for pts with RA and inadequate response to MTX throughout the 52-week period.References:[1]Combe BG, et al.Ann Rheum Dis.2019;78 (Suppl 2):A77.[2]Fautrel B, et al.Rheumatol Int.2018;38:935–47.[3]Smolen JS, et al.Ann Rheum Dis.2017;76:960–77.Disclosure of Interests:Alan Kivitz Shareholder of: AbbVie, Amgen, Gilead, GSK, Pfizer Inc, Sanofi, Consultant of: AbbVie, Boehringer Ingelheim,,Flexion, Genzyme, Gilead, Janssen, Novartis, Pfizer Inc, Regeneron, Sanofi, SUN Pharma Advanced Research, UCB, Paid instructor for: Celgene, Genzyme, Horizon, Merck, Novartis, Pfizer, Regeneron, Sanofi, Speakers bureau: AbbVie, Celgene, Flexion, Genzyme, Horizon, Merck, Novartis, Pfizer Inc, Regeneron, Sanofi, Yoshiya Tanaka Grant/research support from: Asahi-kasei, Astellas, Mitsubishi-Tanabe, Chugai, Takeda, Sanofi, Bristol-Myers, UCB, Daiichi-Sankyo, Eisai, Pfizer, and Ono, Consultant of: Abbvie, Astellas, Bristol-Myers Squibb, Eli Lilly, Pfizer, Speakers bureau: Daiichi-Sankyo, Astellas, Chugai, Eli Lilly, Pfizer, AbbVie, YL Biologics, Bristol-Myers, Takeda, Mitsubishi-Tanabe, Novartis, Eisai, Janssen, Sanofi, UCB, and Teijin, Susan Lee Shareholder of: Gilead Sciences Inc., Employee of: Gilead Sciences Inc., Lei Ye Shareholder of: Gilead Sciences Inc., Employee of: Gilead Sciences Inc., Hao Hu Shareholder of: Gilead Sciences Inc., Employee of: Gilead Sciences Inc., Robin Besuyen Shareholder of: Galapagos, Employee of: Galapagos, Bernard Combe Grant/research support from: Novartis, Pfizer, Roche-Chugai, Consultant of: AbbVie; Gilead Sciences, Inc.; Janssen; Eli Lilly and Company; Pfizer; Roche-Chugai; Sanofi, Speakers bureau: Bristol-Myers Squibb; Gilead Sciences, Inc.; Eli Lilly and Company; Merck Sharp & Dohme; Pfizer; Roche-Chugai; UCB

Abstract
Current treatments have limited effectiveness in treating tumors. The combination of multiple drugs or treatment strategies is widely studied to improve therapeutic effect and reduce adverse effects of cancer therapy. The codelivery system is the key to realize combined therapies. It is necessary to design and construct different codelivery systems in accordance with the variable structures and properties of cargoes and vectors. This review presented the typical design considerations about codelivery vectors for cancer therapy and described the current state of codelivery systems from two aspects: different types of vectors and collaborative treatment strategies. The commonly used loading methods of cargoes into the vectors, including physical and chemical processes, are discussed in detail. Finally, we outline the challenges and perspectives about the improvement of codelivery systems.

Abstract
OBJECTIVE To examine the associations of maternal and child overweight status across multiple time-points with liver fat content in the offspring during young adulthood. DESIGN Cohort study. SETTING ELEMENT Cohort in Mexico City. POPULATION Pregnant women with singleton births (n = 97). METHODS We quantified hepatic triglyceride content (liver fat content) by proton magnetic resonance spectroscopy (1H MRS) and conventional T2-weighted MRIs (3T scanner) in 97 young adults from the ELEMENT birth cohort in Mexico City. Historical records of the cohort were used as a source of pregnancy, and childhood and adolescence anthropometric information, overweight and obesity (OWOB) were defined. Adjusted structural equation models were run to identify the association between OWOB in different life stages with liver fat content (log-transformed) in young adulthood. MAIN OUTCOME Maternal OWOB at the time of delivery was directly and indirectly associated with the liver fat content in the offspring at young adulthood. RESULTS Seventeen percent of the participants were classified as having NAFLD. We found a strong association of OWOB between all periods assessed. Maternal OWOB at time of delivery (β = 1.97, 95% CI 1.28-3.05), and OWOB status in the offspring at young adulthood (β = 3.17, 95% CI 2.10-4.77) were directly associated with the liver fat content in the offspring. Also, maternal OWOB was indirectly associated with liver fat content through offspring OWOB status. CONCLUSION We found that maternal OWOB status is related to fatty liver content in the offspring as young adults, even after taking into account OWOB status and lifestyle factors in the offspring. TWEETABLE ABSTRACT There was an association between pre-pregnancy overweight and the development of NAFLD in adult offspring.

Abstract
BACKGROUND Biofilm formation has been shown to be associated with damaged areas of endoscope channels. It was hypothesized that the passage of instruments and brushes through endoscope channels during procedures and cleaning contributes to channel damage, bacterial attachment and biofilm formation. AIM To compare surface roughness and bacterial attachment in used and new endoscope channels in vivo and in vitro. METHODS Surface roughness of 10 clinically used (retired) and seven new colonoscope biopsy channels was analysed by a surface profiler. For the in-vitro study, a flexible endoscope biopsy forceps was passed repeatedly through a curved 3.0-mm-diameter Teflon tube 100, 200 and 500 times. Atomic force microscopy was used to determine the degree of inner surface damage. The number of Escherichia coli or Enterococcus faecium attached to the inner surface of the new Teflon tube and the tube with 500 forceps passes in 1 h at 37oC was determined by culture. RESULTS The average surface roughness of the used biopsy channels was found to be 1.5 times greater than that of the new biopsy channels (P=0.03). Surface roughness of Teflon tubes with 100, 200 and 500 forceps passes was 1.05-, 1.12- and 3.2-fold (P=0.025) greater than the roughness of the new Teflon tubes, respectively. The number of E. coli and E. faecium attached to Teflon tubes with 500 forceps passes was 2.9-fold (P=0.021) and 4.3-fold (P=0.004) higher compared with the number of E. coli and E. faecium attached to the new Teflon tubes, respectively. CONCLUSION An association was found between endoscope usage with damage to the biopsy channel and increased bacterial attachment.

Abstract
BACKGROUND The benefit and harm of three-field lymphadenectomy for oesophageal cancer are still unknown. The aim of this study was to compare overall survival and morbidity and mortality between three- and two-field lymphadenectomy in patients with oesophageal squamous cell carcinoma. METHODS Between March 2013 and November 2016, patients with squamous cell carcinoma of the middle or distal oesophagus were assigned randomly to open oesophagectomy with three-field (cervical-thoracic-abdominal) or two-field (thoracic-abdominal) lymphadenectomy. No chemo(radio) therapy was given before surgery. This paper reports on the secondary outcomes of the study: pathology and surgical complications. RESULTS Some 400 patients were randomized, 200 in each group. A median of 37 (i.q.r. 30-49) lymph nodes were dissected in the three-field group, compared with 24 (18-30) in the two-field group (P < 0·001). Some 43 of 200 patients (21·5 per cent) in the three-field group had cervical lymph node metastasis. More patients in the three-field group had pN3 disease: 21 of 200 (10·5 per cent) versus 10 of 200 (5·0 per cent) (P = 0·040). The rate and severity of postoperative complications were comparable between the two groups, except that six patients in the three-field arm needed reintubation compared with none in the two-field group (3·0 versus 0 per cent; P = 0·030). The 90-day mortality rate was 0 per cent in the three-field group and 0·5 per cent (1 patient) in the two-field group (P = 1·000). CONCLUSION Oesophagectomy with three-field lymphadenectomy increased the number of lymph nodes dissected and led to stage migration owing to a 21·5 per cent rate of cervical lymph node metastasis. Postoperative complications were largely comparable between two- and three-field lymphadenectomy. Registration number: NCT01807936 ( https://www.clinicaltrials.gov).

Abstract
Glutamine addiction is a major feature of glioma cells and plays an important role in its growth and proliferation. GLUL (glutamate-ammonia ligase), which catalyzes glutamate and ammonia to synthesize glutamine, plays a crucial role in tumor growth and proliferation. We attempt to determine a pathway that limits the growth of glioma by targeting GLUL and explore effective strategies blocking glutamine metabolism. We note that miRNAs mediate regulation of genes participating directly or indirectly in cancer cell metabolism. The regulatory roles of miRNAs on metabolic enzymes are widely discussed, however miRNAs regulation of glutamine metabolism by targeting GLUL in glioma has not yet been reported. Here, we examined both the expression and functions of GLUL in glioma cells. Findings indicated that the expression of GLUL was upregulated in high-grade compared to low-grade glioma cells. Knockdown of GLUL effectively inhibited proliferation, migration and invasion of glioma cells in vitro. Bioinformatics analyses, as well as dual-luciferase reporter assays, revealed that miR-140-5p bound to GLUL mRNA at the 3'-UTR location. Furthermore, the proliferation, migration and invasion of glioma cells were also repressed by miR-140-5p. Overall, these results showed that miR-140-5p exerted its inhibitory effects on proliferation, migration and invasion in glioma cells through downregulating GLUL. Thus, the miR-140-5p/GLUL axis may function as a potential target for glioma treatment.

Abstract
OBJECTIVES Malnutrition of vitamin A (retinol) and vitamin E (α-tocopherol, α-TOH) was observed in type 2 diabetes mellitus (T2DM) or dementia patients. However, how these vitamins affect cognitive function of subjects with T2DM was seldom reported. The objective of this study was to determine the association of circulating retinol and α-TOH with cognition in aging subjects with T2DM. METHODS A total of 448 T2DM subjects and 448 age, gender and education matched control subjects (aged 55-75 years) were included in the study. Demographic characters of the participants were collected. Food frequency questionnaire (FFQ) method was used to collect dietary intake information. To assess the status of cognition, the MoCA test was used. Circulating retinol and α-TOH levels were compared between T2DM and non-T2DM subjects. Correlation of circulating retinol and α-TOH levels with cognitive function was analyzed in T2DM subjects. The effect of serum retinol and α-TOH levels on the risk of MCI in T2DM patients was explored. RESULTS We found that T2DM-MCI subjects demonstrate lower serum retinol level than T2DM-nonMCI subjects (P < 0.01). Serum retinol level was positively correlated to cognitive function in T2DM subject (P < 0.05). T2DM subjects with higher circulating retinol level demonstrate higher cognitive scores in visual and executive, attention, language, memory and delayed recall domains (P < 0.05). CONCLUSION Diminished circulating retinol predicts an increased risk of MCI in T2DM patients. Our findings provide suggestions that optimal retinol nutritional status might benefit cognition and decrease the risk of MCI in aging subjects with T2DM.

Abstract
With the rapid developments in compact devices, the multi-function and reconfigurability of nanostructures are highly appreciated, while still very challenging. A majority of devices are usually mono-functional or hard to switch between different functions in one design. In this paper, we proposed graphene-wrapped core-shell nanowires to realize real-time reconfigurable sensors and nanoantenna by tuning the Fermi energies of graphene layers at the surfaces of core and shell, respectively. Owing to the electromagnetic coupling between the two graphene layer, two corresponding Fano resonances of scattering can arise in the Terahertz spectrum, which arises from the interference of bright modes and dark modes. Around the Fano resonances, the scattering can be considerably resonant (as an antenna) or suppressed (as a sensor). Interestingly, the field distributions are distinct at the suppressed scattering states for the two Fano resonances. The presented reconfigurable nanostructures may offer promising potentials for integrated and multi-functional electromagnetic control such as dynamic sensing and emission.

Abstract
Barley yellow dwarf (BYD) is a major virus disease which dramatically reduces wheat yield. Introducing BYD resistance genes into commercial varieties has been proven to be effective in reducing damage caused by barley yellow dwarf virus (BYDV). However, only one major resistance gene is readily deployable for breeding; Bdv2 derived from Thinopyrum intermedium is deployed as a chromosomal translocation. In this study, a double haploid (DH) population was developed from a cross between XuBYDV (introduced from China showing very good resistance to BYD) and H-120 (a BYD-sensitive Chinese accession), and was used to identify QTL for BYD resistance. The population was genotyped using an Infinium iSelect bead chip array targeting 90K gene-based SNPs. The disease resistance of DH lines inoculated with BYDV was assessed at the heading stage. The infections were assessed by tissue blot immunoassay (TBIA). Three new QTL were identified on chromosomes 5A, 6A, and 7A for both symptom and TBIA, with all three resistance alleles being inherited from XuBYDV. Some DH lines with the resistance alleles from all three QTL showed high level resistance to BYD. These new QTL will be useful in breeding programs for pyramiding BYD resistance genes.

Abstract
Periodontal disease is the main reason for tooth loss in adults. Tissue engineering and regenerative medicine are advanced technologies used to manage soft and hard tissue defects caused by periodontal disease. We developed a transforming growth factor-β3/chitosan sponge (TGF-β3/CS) to repair periodontal soft and hard tissue defects. We investigated the proliferation and osteogenic differentiation behaviors of primary human periodontal ligament stem cells (hPDLSCs) to determine the bioactivity and potential application of TGF-β3 in periodontal disease. We employed calcein-AM/propidium iodide (PI) double labeling or cell membranes (CM)-Dil labeling coupled with fluorescence microscopy to trace the survival and function of cells after implantation in vitro and in vivo. The mineralization of osteogenically differentiated hPDLSCs was confirmed by measuring alkaline phosphatase (ALP) activity and calcium content. The levels of COL I, ALP, TGF-βRI, TGF-βRII, and Pp38/t-p38 were assessed by western blotting to explore the mechanism of bone repair prompted by TGF-β3. When hPDLSCs were implanted with various concentrations of TGF-β3/CS (62.5-500 ng/mL), ALP activity was the highest in the TGF-β3 (250 ng/mL) group after 7 d (p < 0.05 vs. control). The calcium content in each group was increased significantly after 21 and 28 d (p < 0.001 vs. control). The optimal result was achieved by the TGF-β3 (500 ng/mL) group. These results showed that TGF-β3/CS promotes osteogenic differentiation of hPDLSCs, which may involve the p38 mitogen-activated protein kinase (MAPK) signaling pathway. TGF-β3/CS has the potential for application in the repair of incomplete alveolar bone defects.

Abstract
Abstract
Background
After activation by different factors, platelets can release a large number of platelet microparticles (PMPs), and continue to play a more durable and extensive role in promoting inflammation and thrombosis. Previous studies by our group have shown that PMPs can promote endothelial cell migration and lumen formation in vitro, and promote the release of inflammatory factors from monocytes. However, it is unclear whether PMPs can promote angiogenesis in the plaque and promote vascular wall inflammation and further lead to plaque instability.
Purpose
To investigate the effect of platelet microparticles (PMPs) from C57BL/6 mice on promoting atherosclerotic plaque formation and plaque stability in ApoE−/− mice.
Methods
Forty male apolipoprotein E knockout (ApoE−/−) mice, aged 8 weeks and fed for 4 weeks with high-fat diet, were randomly divided into four groups (n=10 in each group)according to the table of random digit. The mice were respectively injected with PBS (PBS group), PMPs-free supernatants (SUP group), low-dose PMPs (LDP group) and high-dose PMPs (HDP group) once a week through tail vein injection for 8 weeks. At the end of the experiment, the mice were euthanized and the blood samples were collected to detect blood routine, blood lipids, liver and kidney function and inflammatory factors including CRP, IL-1β, TNF-α; The aorta and brachiocephalic trunk were sampled to detect the atherosclerotic plaque formation. Oil Red O staining, H&E staining, Masson staining and immunohistochemistry (CD68, MMP-9, α-SMA) were used to examine the stability of the atherosclerotic plaque in each group.
Results
There were no significant differences in body weight, blood routine (WBC, RBC, PLT, HGB), blood lipids (TG, TCH, LDL, HDL), liver (ALT, AST)and kidney function (UN, Cr)in each group. The levels of serum CRP, IL-1β and TNF-α in LDP group and HDP group were significantly higher than those in PBS group and SUP group (P<0.05). The total area of aortic atherosclerotic plaques in LDP group and HDP group were significantly greater than those in PBS group and SUP group (P<0.05). Compared with the PBS group, the lipid cores of the plaques in the other three groups were significantly increased (P<0.05). The content of collagen and the amount of smooth muscle cells in the plaques were significantly lower in HDP group than in PBS group (P<0.05), while macrophages increased significantly in HDP group (P<0.05).
Conclusion
PMPs promote the formation of atherosclerotic plaques in high-fat-fed ApoE−/− mice, as well as macrophage infiltration and inflammation in the plaques, reduce the content of collagen and the amount of smooth muscle cells, thus decreasing the stability of plaques.
