Abstract
Diabetes, a group of metabolic disorders, constitutes an important global health problem. Diabetes and its complications place a heavy financial strain on both patients and the global healthcare establishment. The lack of effective treatments contributes to this pessimistic situation and negative outlook. Exosomes released from mesenchymal stromal cells (MSCs) have emerged as the most likely new breakthrough and advancement in treating of diabetes and diabetes-associated complication due to its capacity of intercellular communication, modulating the local microenvironment, and regulating cellular processes. In the present review, we briefly outlined the properties of MSCs-derived exosomes, provided a thorough summary of their biological functions and potential uses in diabetes and its related complications.

Abstract
Background: Mechanical forces are indispensable for bone healing, disruption of which is recognized as a contributing cause to nonunion or delayed union. However, the underlying mechanism of mechanical regulation of fracture healing is elusive. Methods: We used the lineage-tracing mouse model, conditional knockout depletion mouse model, hindlimb unloading model and single-cell RNA sequencing to analyze the crucial roles of mechanosensitive protein polycystin-1 (PC1, Pkd1) promotes periosteal stem/progenitor cells (PSPCs) osteochondral differentiation in fracture healing. Results: Our results showed that cathepsin (Ctsk)-positive PSPCs are fracture-responsive and mechanosensitive and can differentiate into osteoblasts and chondrocytes during fracture repair. We found that polycystin-1 declines markedly in PSPCs with mechanical unloading while increasing in response to mechanical stimulus. Mice with conditional depletion of Pkd1 in Ctsk+ PSPCs show impaired osteochondrogenesis, reduced cortical bone formation, delayed fracture healing, and diminished responsiveness to mechanical unloading. Mechanistically, PC1 facilitates nuclear translocation of transcriptional coactivator TAZ via PC1 C-terminal tail cleavage, enhancing osteochondral differentiation potential of PSPCs. Pharmacological intervention of the PC1-TAZ axis and promotion of TAZ nuclear translocation using Zinc01442821 enhances fracture healing and alleviates delayed union or nonunion induced by mechanical unloading. Conclusion: Our study reveals that Ctsk+ PSPCs within the callus can sense mechanical forces through the PC1-TAZ axis, targeting which represents great therapeutic potential for delayed fracture union or nonunion.

Abstract
PURPOSE Nutrition intake is one of the modifiable risk factors for cognitive decline. Whether energy and protein intakes alter the association between pulmonary function (PF) and cognition has not been studied. METHODS We made use of information from the U.S. National Health and Nutrition Examination Survey (NHANES) 2011-2012. PF measures, including forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and peak expiratory flow (PEF), were calculated, whereas cognitive function was assessed through four tests: the Immediate Recall test (IRT), the Delayed Recall test (DRT), the Animal Fluency test (AFT) and the Digit Symbol Substitution test (DSST). Energy and protein intakes were measured using the 24-h dietary recall method. Weighted generalized linear regression was performed upon adjustment for covariates. Further interaction analyses were conducted to investigate the effect of energy and protein intakes on the association between PF and cognition. RESULTS We finally included 803 participants aged ≥ 60 years (54.4% female, weighted value). After adjusting for covariates, multiple measures (including FEV1, FVC, PEF, and composite PF) were all positively associated with better global cognition and the DSST score (P < 0.05). A stronger positive association between the DSST score and FEV1 (P for interaction = 0.001), FVC (P for interaction = 0.004), PEF (P for interaction = 0.003), and composite PF (P for interaction = 0.001) in lower energy intake. Similar results were observed in lower protein intake (all P for interaction < 0.05). CONCLUSION Higher PF was independently associated with improved specific components of cognitive function (i.e., the DSST score). The positive association between PF and the DSST score was stronger in individuals with lower energy and protein intakes.

Abstract
Aristolochic acid nephropathy (AAN) has drawn increasing public attention. Organic anion transporters (OATs) are considered to be responsible for mediating nephrotoxicity of aristolochic acids (AAs), as AAs are typical OAT1 substrates that exhibit anionic properties and contain one hydrophobic domain. Inspired by the OAT1 three-dimensional structure or substrate/protein interactions involved in transport, we designed a magnetic polymeric hybrid, mimicking the effect of basic and aromatic residues of OAT1, for efficient enriching aristolochic acid I (AA I) and aristolochic acid II (AA II) in Traditional Chinese patent medicines (TCPM). N, N-dimethylaminopropyl acrylamide (DMAPAm) was used as a cationic monomer and copolymerized with divinylbenzene (DVB) onto the surface of monodisperse magnetic nanoparticles (denoted as MNs@SiO2T-DvbDam). The magnetic polymer hybrid demonstrated high selectivity and capacity for AAs, which was mainly attributed to (1) electrostatic interactions from the cationic or basic moiety of DMAPAm and (2) the hydrophobic and π-π stacking interactions from the aromatic ring of DVB. Additionally, the surface of the hybrid exhibited amphiphilic property according to the ionization of DMAPAm, thus improving the compatibility of the adsorbent with the aqueous sample matrix. This strategy was proven to be robust in the analysis of real drug samples, which was characterized by a good linearity, high recovery and satisfactory reusability. This work confirmed that the proposed tool could be a promising candidate for enhancing the extraction selectivity of AAs in Traditional Chinese medicines (TCM).

Abstract
To investigate the safety and feasibility of gasless total endoscopic resection of deep lobe parotid gland tumors via a postauricular hairline plus temporal approach. The approach was designed as: a 4 to 5 cm main incision was designed at the postauricular hairline, and a 0.5 cm auxiliary incision was designed in the temporal hairline. The operating cavity was established with the assistance of a special retractor. "Anterograde" dissection of the facial nerve was performed throughout the procedure, along with partial or total gland removal of the tumor. All 16 operations were successfully completed without conversion to open surgery. During the operation, the trunk and branches of the facial nerve were completely preserved, the tumor was completely removed, and the incision healed. Six patients had mild facial paralysis after operation, and recovered completely after 3 to 6 months. There was no salivary fistula, Frey syndrome, infection, or other complications. The postoperative incision was concealed and the aesthetic effect was good. The postauricular hairline plus temporal approach gasless total endoscopic parotidectomy is safe and feasible. This technique can achieve the complete dissection of the total trunk to the branches of the facial nerve, and has good access to the tumors located in any part of the parotid gland region. On the basis of radical resection of the tumor, it achieves minimally invasive and aesthetic improvement.

Abstract
Skeletal stem/progenitor cell (SSPC) senescence is a major cause of decreased bone regenerative potential with aging, but the causes of SSPC senescence remain unclear. In this study, we revealed that macrophages in calluses secrete prosenescent factors, including grancalcin (GCA), during aging, which triggers SSPC senescence and impairs fracture healing. Local injection of human rGCA in young mice induced SSPC senescence and delayed fracture repair. Genetic deletion of Gca in monocytes/macrophages was sufficient to rejuvenate fracture repair in aged mice and alleviate SSPC senescence. Mechanistically, GCA binds to the plexin-B2 receptor and activates Arg2-mediated mitochondrial dysfunction, resulting in cellular senescence. Depletion of Plxnb2 in SSPCs impaired fracture healing. Administration of GCA-neutralizing antibody enhanced fracture healing in aged mice. Thus, our study revealed that senescent macrophages within calluses secrete GCA to trigger SSPC secondary senescence, and GCA neutralization represents a promising therapy for nonunion or delayed union in elderly individuals.

Abstract
Exercise can prevent osteoporosis and improve immune function, but the mechanism remains unclear. Here, we show that exercise promotes reticulocalbin-2 secretion from the bone marrow macrophages to initiate bone marrow fat lipolysis. Given the crucial role of lipolysis in exercise-stimulated osteogenesis and lymphopoiesis, these findings suggest that reticulocalbin-2 is a pivotal regulator of a local adipose-osteogenic/immune axis. Mechanistically, reticulocalbin-2 binds to a functional receptor complex, which is composed of neuronilin-2 and integrin beta-1, to activate a cAMP-PKA signaling pathway that mobilizes bone marrow fat via lipolysis to fuel the differentiation and function of mesenchymal and hematopoietic stem cells. Notably, the administration of recombinant reticulocalbin-2 in tail-suspended and old mice remarkably decreases bone marrow fat accumulation and promotes osteogenesis and lymphopoiesis. These findings identify reticulocalbin-2 as a novel mechanosensitive lipolytic factor in maintaining energy homeostasis in bone resident cells, and it provides a promising target for skeletal and immune health.

Abstract
A specific bone capillary subtype, namely type H vessels, with high expression of CD31 and endomucin, was shown to couple angiogenesis and osteogenesis recently. The number of type H vessels in bone tissue declines with age, and the underlying mechanism for this reduction is unclear. Here, we report that microRNA-188-3p (miR-188-3p) involves this process. miRNA-188-3p expression is upregulated in skeletal endothelium and negatively regulates the formation of type H vessels during ageing. Mice with depletion of miR-188 showed an alleviated age-related decline in type H vessels. In contrast, endothelial-specific overexpression of miR-188-3p reduced the number of type H vessels, leading to decreased bone mass and delayed bone regeneration. Mechanistically, we found that miR-188 inhibits type H vessel formation by directly targeting integrin β3 in endothelial cells. Our findings indicate that miR-188-3p is a key regulator of type H vessel formation and may be a potential therapeutic target for preventing bone loss and accelerating bone regeneration.

Abstract
Mucosal healing is a key treatment goal for inflammatory bowel disease, and adequate epithelial regeneration is required for an intact gut epithelium. However, the underlying mechanism is unclear. Long non-coding RNAs (lncRNAs) have been reported to be involved in the development of inflammatory bowel disease. Here, we report that a lncRNA named Gm31629, decreases in intestinal epithelial cells in response to inflammatory stimulation. Gm31629 deficiency leads to exacerbated intestinal inflammation and delayed epithelial regeneration in dextran sulfate sodium (DSS) -induced colitis model. Mechanistically, Gm31629 promotes E2F pathways and cell proliferation by stabilizing Y-box protein 1 (YB-1), thus facilitating epithelial regeneration. Genetic overexpression of Gm31629 protects against DSS-induced colitis in vivo. Theaflavin 3-gallate, a natural compound mimicking Gm31629, alleviates DSS-induced epithelial inflammation and mucosal damage. These results demonstrate an essential role of lncRNA Gm31629 in linking intestinal inflammation and epithelial cell proliferation, providing a potential therapeutic approach to inflammatory bowel disease.

Abstract
Objective: To observe the efficacy and safety of S(+)-ketamine combined with sufentanil for patient-controlled intravenous analgesia (PCIA) in elderly patients undergoing laparoscopic radical resection of rectal cancer and explore its impact on patients' early recovery. Methods: One hundred and ten patients undergoing laparoscopic radical resection of rectal cancer in Affiliated Cancer Hospital of Zhengzhou University from December 2020 to March 2021, were divided into two groups (n=55) using a random number table: group S received PCIA, with continuous infusion of S(+)-ketamine combined with sufentanil, while group C received PCIA, with continuous infusion of sufentanil. PCIA was initiated at the end of the surgery, and the formulations were as follows: group S, S(+)-ketamine (1.44 mg/kg), sufentanil (1.05 μg/kg), ketorolac tromethamine (2.0 mg/kg) and tropisetron (5 mg), in 100 ml of normal saline; group C: sufentanil (1.50 μg/kg), ketorolac tromethamine (2.0 mg/kg) and tropisetron (5 mg), in 100 ml of normal saline. Postoperative visual analogue scale (VAS) and Ramsay sedation scale were recorded at 6, 12, 24, 36, 48 h after the surgery. The incidence of remedial analgesia, the effective compressions number of PCI during 48 h after the operation. Time to first ambulation, time to first anal exhaust, time to resume oral feeding were recorded. The occurrence of adverse effects was compared between the two groups. Results: A total of 10 patients were excluded during the study, including 4 cases of conversion to laparotomy, 3 cases of dropping out of the study, and 3 cases with operation time more than 4 hours. Finally, 50 cases in group S and 50 cases in group C completed the study. There were no significant differences in VAS scores and Ramsay sedation sores at all time points between two groups (all P>0.05). Likewise, there were also no significant differences in the number of remedial analgesia and effective compressions of PCIA during 48 h after the operation between the two groups (both P>0.05). The total dosage of sufentanil consumption in group S [(64±9) μg] was lower than that in group C [(95±12) μg] within 48 h of PCIA, with a statistically significant difference (P<0.001). Time to first ambulation in group S was (1.1±0.2) d, which was shorter than that in group C [(1.6±0.5) d], and the difference was statistically significant (P<0.001). Likewise, time to first anal exhaust in group S [(1.3±0.4) d] was shorter than that in group C [(1.8±0.6) d], with a statistically significant difference (P<0.001). Additionally, time to resume oral feeding in group S was (2.5±0.6) d, which was shorter than that in group C [(3.1±0.7) d], and there was a statistically significant difference (P<0.001). The incidence of nausea, vomiting and pruritus in group S were 4.0%, 2.0% and 0, which were lower than that in group C (16.0%, 10% and 8.0%, respectively), with statistically significant differences (all P<0.05). No case with psychiatric symptoms was found in both groups. Conclusion: When used for postoperative intravenous analgesia in elderly patients undergoing laparoscopic radical resection of rectal cancer, S(+)-ketamine combined with sufentanil can provide satisfactory analgesic effects, decrease total consumption of sufentanil and the incidence of adverse effects, and thus facilitate patients' early recovery.

Abstract
Background Non pharmaceutical interventions (NPI) including hand washing directives were implemented in China and worldwide to combat the COVID-19 pandemic, which are likely to have had impacted a broad spectrum of enteric pathogen infections. Methods Etiologically diagnostic data from 45 937 and 67 395 patients with acute diarrhea between 2012 and 2020, who were tested for seven viral pathogens and 13 bacteria respectively, were analyzed to assess the changes of enteric pathogen infections in China during the first COVID-19 pandemic year compared to pre-pandemic years. Findings Test positive rates of all enteric viruses decreased during 2020, compared to the average levels during 2012−2019, with a relative decrease of 71•75% for adenovirus, 58•76% for norovirus, 53•50% for rotavirus A, and 72•07% for the combination of other four uncommon viruses. In general, a larger reduction of positive rate in viruses was seen among adults than pediatric patients. A rebound of rotavirus A was seen after September 2020 in North China rather than South China. Test positive rates of bacteria decreased during 2020, compared to the average levels during 2012−2019, excepting for nontyphoidal Salmonella and Campylobacter coli with 66•53% and 90•48% increase respectively. This increase was larger for pediatric patients than for adult patients. Interpretation The activity of enteric pathogens changed profoundly alongside the NPIs implemented during the COVID-19 pandemic in China. Greater reductions of the test positive rates were found for almost all enteric viruses than for bacteria among acute diarrhea patients, with further large differences by age and geography. Lifting of NPIs will lead to resurgence of enteric pathogen infections, particularly in children whose immunity may not have been developed and/or waned.

Abstract
Abstract
Study question
Does the presence of smooth endoplasmic reticulum clusters (sERCs) in oocytes affect the human embryo ploidy?
Summary answer
The euploidy rate of embryos originating from sERCs + oocytes is lower
What is known already
While an expert panel strongly recommended that sERCs+ oocytes should not be inseminated, some normal healthy babies derived from sERCs+ oocytes have been reported. In previous studies have shown that declined fertilization rate and lower proportions of good quality embryos are found in oocytes showing sERCs. The updating findings of the molecular status of sERC+ oocytes elucidated the sERCs+ oocytes may have impaired chromosomal segregation ability. However, no study reveals the relation between sERCs and embryo ploidy.
Study design, size, duration
A retrospective study enrolled 129 preimplantation genetic testing (PGT) cycles from January 2017 to March 2020 at Chang Gung Memorial Hospital, Lonkou.
Participants/materials, setting, methods
ICSI fertilization rate, Day5 usable blastocyst rate (D5UBR), total usable blastocyst rate (TUBR), euploidy rate, mosaic rate, and aneuploidy rate are investigated between embryo originating from sERCs+ and sERCs- oocytes.
Main results and the role of chance
Although higher TBUR in blastocyst derived from sERCs+ oocytes than sERCs- group (73.7% vs. 62.5%) but accompanied lower euploidy rate (7% vs. 29%) and higher aneuploid rate (79% vs. 54%).
Limitations, reasons for caution
Limited sample size, need a large-scale study to confirm the conclusion. The live-birth rate per embryo transfer cycle was not included for analysis. As we did not perform polar body analysis, we cannot state for sure that embryonic aneuploidy was related to the oocyte.
Wider implications of the findings: This study demonstrates that embryos originating from sERCs+ oocytes have a lower euploidy rate.

Abstract
PURPOSE Increasing evidences suggest dysfunctions of microRNAs (miRNAs) are playing important part in tumors. Therefore, the role of miR-802 in osteosarcoma (OS) was exploited. The object was to evaluate the effect of miR-802 and verify its influence on p27 Kip1 (p27) in OS. METHODS RT-qPCR experiment was used to detect miR-802 and p27 expression in OS tissues and cells. We explored the function of miR-802 through Transwell assays. The phosphoinositide 3-kinase (PI3K)/AKT serine/threonine kinase pathway and epithelial-mesenchymal transition (EMT) was detected by Western blot assays. Luciferase assay was used to testify the target of miR-802. RESULTS MiR-802 expression was elevated in OS, which was related to poor clinical outcome in OS patients. MiR-802 overexpression promoted OS migration, invasion and EMT. Further, p27 is a direct target of miR-802. P27 elevation counteracted the promotion effect of OS on EMT, migration and invasion induced by miR-802. In addition, miR-802 overexpression inactivated PI3K/AKT pathway via targeting p27 in OS. CONCLUSION MiR-802 promoted the progress of EMT, migration and invasion in OS via targeting p27. This newly identified miR-802/p27/PI3K/AKT axis may represent potential targets for OS.

Abstract
Objective: To investigate the effects of positive end-expiratory pressure (PEEP) setting of mechanical ventilation guided by esophageal pressure in the treatment of patients with traumatic craniocerebral injury combined with acute respiratory distress syndrome (ARDS). Methods: The retrospective cohort study was conducted. From June 2016 to June 2018, 55 patients with traumatic craniocerebral injury combined with ARDS who met the inclusion criteria were admitted to Zhengzhou Central Hospital Affiliated to Zhengzhou University. According to PEEP setting method, 28 patients were allocated to esophageal pressure group (17 males and 11 females, aged (40±13) years) and 27 patients were allocated to PEEP-fractional concentration of inspired oxygen (FiO2) table group (18 males and 9 females, aged (38±10) years). Patients in the 2 groups were treated with mechanical ventilation guided by lung protective ventilation strategy, and the optimal PEEP at 0 (immediately), 24, 48, and 72 h after treatment was determined according to esophageal pressure and PEEP-FiO2 table, respectively. The mechanical ventilation parameters in the 2 groups were adjusted according to the optimal PEEP. The transpulmonary end-expiratory pressure, pulmonary compliance, oxygen index, central venous pressure, mean arterial pressure, and intracranial pressure at 24, 48, and 72 h after treatment were recorded. Data were statistically analyzed with analysis of variance for repeated measurement, chi-square test, independent sample t test, and Bonferroni correction. Results: The optimal PEEP of patients in esophageal pressure group at 0, 24, 48, and 72 h after treatment was (12.4±3.9), (11.2±3.5), (13.4±2.6), and (13.2±3.6) cmH2O (1 cmH2O=0.098 kPa), respectively, which was significantly higher than (8.2±2.5), (7.4±2.2), (8.3±2.3), and (8.5±2.5) cmH2O in PEEP-FiO2 table group, respectively (t=4.702, 4.743, 7.849, 5.623, P<0.01). The transpulmonary end-expiratory pressure and pulmonary compliance at 24, 48, and 72 h after treatment and oxygen index at 48 and 72 h after treatment of patients in esophageal pressure group were significantly higher than those in PEEP-FiO2 table group (t=17.852, 20.586, 19.532, 4.752, 5.256, 7.446, 2.342, 4.178, P<0.05 or P<0.01). The central venous pressure of patients in esophageal pressure group at 24, 48, and 72 h after treatment was significantly higher than that in PEEP-FiO2 table group (t=12.632, 5.247, 8.994, P<0.01), and there was no statistically significant difference in mean arterial pressure of patients between the 2 groups at 24, 48, and 72 h after treatment (P>0.05). The intracranial pressure of patients in esophageal pressure group was higher than that in PEEP-FiO2 table group at 24, 48, and 72 h after treatment, but there was no statistically significant difference between the 2 groups (P>0.05). Conclusions: For patients with traumatic craniocerebral injury combined with ARDS, the optimal PEEP can be set under the guidance of esophageal pressure method, and the mechanical ventilation parameters adjusted according to the optimal PEEP can improve lung compliance and accelerate recovery of lung function more effectively, with no adverse effect in mean arterial pressure and intracranial pressure.

Abstract
Objective: To evaluate the 4-year clinical outcomes of patients following Firesorb bioresorbable scaffold (BRS) implantation. Methods: The study reported the 4-year follow-up results of the FUTURE I study. FUTURE I was a prospective, single-center, open-label, first-in-man study which evaluated the feasibility, preliminary safety, and efficacy of Firesorb stent in the treatment of coronary artery stenosis. A total of 45 patients with single de novo lesions in native coronary arteries ,who hospitalized in Fuwai Hospital from January to March 2016 were enrolled. After successfully stent implantation these patients were randomized in a 2∶1 ratio into cohort 1 (n=30) or cohort 2 (n=15). The patients in cohort 1 underwent angiographic, IVUS or OCT examination at 6 months and 2 years; and cohort 2 underwent angiographic, IVUS or OCT at 1 and 3 years. All patients underwent clinical follow-up at 1, 6 months and 1 year and annually thereafter up to 5 years. The primary endpoint was target lesion failure (TLF, including cardiac death, target vessel myocardial infarction, and ischemia-driven target lesion revascularization). Secondary endpoints included patient-oriented composite endpoint (PoCE, defined as composite of all death, all miocardial infarction, or any revascularization). Results: A total of 45 patients were enrolled and implanted with Firesorb BRS, including 35 males (77.8%), and the age was (54.4±9.3) years. At 4 years, 10 patients in cohort 1 were reexamined by coronary angiography and OCT examination. Among them, 2 patients' stents were completely degraded and absorbed. Compared with the OCT images of the other 8 patients in cohort 2 at 3 years, the degree of stent degradation was increased, and no stent adherence was found. The 4-year clinical follow-up rate was 100%. In 4-year clinical following up, 2 patients suffered PoCE (4.4%): 1 patient underwent non-target vessel revascularization the day after index procedure and target vessel revascularization (Non-target lesion revascularization) at 2-year imaging follow-up; the other patient underwent target lesion revascularization during imaging follow-up at 4 years but not due to ischemic driven. There was no scaffold thrombosis or TLF events through 4 years. Conclusions: Four years after the implantation, complete degradation and absorption of the Firsorb stent are evidenced in some patients. Firesorb stent is feasible and effective in the treatment of patients with non-complex coronary lesions.

Abstract
Autophagy is an evolutionarily conserved intracellular process and is considered one of the main catabolism pathways. In the process of autophagy, cells are digested nonselectively or selectively to recover nutrients and energy, so it is regarded as an antiaging process. In addition to the essential role of autophagy in cellular homeostasis, autophagy is a stress response mechanism for cell survival. Here, we review recent literature describing the pathway of autophagy and its role in different bone cell types, including osteoblasts, osteoclasts, and osteocytes. Also discussed is the mechanism of autophagy in bone diseases associated with bone homeostasis, including osteoporosis and Paget's disease. Finally, we discuss the application of autophagy regulators in bone diseases. This review aims to introduce autophagy, summarize the understanding of its relevance in bone physiology, and discuss its role and therapeutic potential in the pathogenesis of bone diseases such as osteoporosis.

Abstract
Obesity is characterized by the expansion of adipose tissue which is partially modulated by adipogenesis. In the present study, we identified five differentially expressed genes by incorporating two adipogenesis-related datasets from the GEO database and their correlation with adipogenic markers. However, the role of scavenger receptor class A member 3 (SCARA3) in obesity-related disorders has been rarely reported. We found that Scara3 expression in old adipose tissue-derived mesenchymal stem cells (Ad-MSCs) was lower than it in young Ad-MSCs. Obese mice caused by deletion of the leptin receptor gene (db/db) or by a high-fat diet both showed reduced Scara3 expression in inguinal white adipose tissue. Moreover, hypermethylation of SCARA3 was observed in patients with type 2 diabetes and atherosclerosis. Data from the CTD database indicated that SCARA3 is a potential target for metabolic diseases. Mechanistically, JUN was predicted as a transcriptional factor of SCARA3 in different databases which is consistent with our further bioinformatics analysis. Collectively, our study suggested that SCARA3 is potentially associated with age-related metabolic dysfunction, which provided new insights into the pathogenesis and treatment of obesity as well as other obesity-associated metabolic complications.

Abstract
This study was conducted to determine the effect of feeding frequency on growth performance, carcass traits, and apparent nutrient digestibility in geese from 28 to 70 D of age. In experiment 1, a total of 240 geese were distributed in a completely randomized design into 4 treatments and 6 replicates of 10 birds each. The treatments were free access to the feeder (ad libitum) and access to the feeder 3, 4, and 5 times daily. Geese fed 3 times daily had a lower (P < 0.05) BW, ADG, and ADFI and a higher (P = 0.064) feed conversion ratio (FCR) from 28 to 41 D of age compared with the other groups. Geese fed 4 times daily had a higher (P < 0.05) ADG and ADFI and a lower (P < 0.05) FCR from 42 to 55 D of age compared with ad libitum fed geese. Geese fed 3 times daily had a higher (P < 0.05) ADG from 56 to 69 D of age than geese fed ad libitum and 4 times daily. No differences (P > 0.05) in BW, ADFI, ADG, and FCR were observed between ad libitum and feeding frequency groups from 28 to 69 D of age. Carcass traits and gastrointestinal development were not affected (P > 0.05) by feeding frequency. In experiment 2, the apparent nutrient digestibility in geese from 71 to 77 D of age fed using different feeding frequencies was determined using the total fecal collection method. Feeding frequency did not affect (P > 0.05) the apparent digestibility of DM, CP, crude ash, calcium, phosphorous, or ether extract in geese. Our study demonstrates for the first time that compensatory growth can be gained by enhancing feed intake when a lower feeding frequency is imposed on geese. Both ad libitum feeding and fixed feeding frequency for 3 to 5 times daily are suitable for geese from 28 to 70 D of age to achieve optimum production.

Abstract
Background
With the outbreak of pandemics such as SARS, MERS and COVID-19 etc., making full use of artificial intelligence (AI) become the focus of social discussion. Some experts think AI can reduce infection probability of medical staffs and improve medical efficiency, while opponents believe AI will increase unemployment and medical ethical crises. We try to answer the question: From public perspective, could AI replace human doctors?
Methods
According to occupational status and biological gender, we select four groups as respondents: on-job and retired men, on-job and retired women. We investigate their attitudes towards AI application in medical field. After collecting 400 anonymous questionnaires, we use sample statistics, ANOVA and cluster method (CFSFDP) to find out cognitive similarities and differences between different groups.
Results
Reliability (Cronbach's alpha coefficient) and validity (KMO test) of questionnaires are 0.740 and 0.875 respectively. To the four groups, there are significant (p < 0.01) differences in answers of 7 questions but non-significant differences in the remaining 3 questions. By CFSFDP, questionnaires are automatically grouped into two clusters. Largest group in two clusters are on-job women and on-job men, respectively. Although 82.5% of respondents pay attention to news about AI, the overall average score for “public attitude to AI application in medical field” is 2.828 (full-score is 5.000), below neutral-score (3.000).
Conclusions
To AI application in medical field, cognitive differences among different groups are in existence, especially between on-job men and women. But in general, the public held a negative attitude towards the AI application in medical field, and trust human doctors more.
Key messages
According to the survey, it seems that AI is lesser probability to replace human doctors in recent years. It is also necessary to consider the public attitudes when promoting medical AI.

Abstract
In the central nervous system, hyperpolarization-activated cyclic nucleotide-gated (HCN) channels are essential to maintain normal neuronal function. Recent studies have shown that HCN channels may be involved in the pathological process of ischemic brain injury, but the mechanisms remain unclear. Autophagy is activated in cerebral ischemia, but its role in cell death/survival remains controversial. In this study, our results showed that the HCN channel blocker ZD7288 remarkably decreased the percentage of apoptotic neurons and corrected the excessive autophagy induced by oxygen-glucose deprivation followed by reperfusion (OGD/R) in hippocampal HT22 neurons. Furthermore, in the OGD/R group, p-mTOR, p-ULK1 (Ser757), and p62 were significantly decreased, while p-ULK1 (Ser317), atg5, and beclin1 were remarkably increased. ZD7288 did not change the expression of p-ULK1 (Ser757), ULK1 (Ser317), p62, Beclin1, and atg5, which are involved in regulating autophagosome formation. Besides, we found that OGD/R induced a significant increase in Cathepsin D expression, but not LAMP-1. Treatment with ZD7288 at 10 μmol/L in the OGD/R group did not change the expression of cathepsin D and LAMP-1. However, chloroquine (CQ), which decreases autophagosome-lysosome fusion, eliminated the correction of excessive autophagy and neuroprotection by ZD7288. Besides, shRNA knockdown of HCN2 channels significantly reduced the accumulation of LC3-II and increased neuron survival in the OGD/R and transient global cerebral ischemia (TGCI) models, and CQ also eliminated the effects of HCN2-shRNA. Furthermore, we found that the percentage of LC3-positive puncta that co-localized with LAMP-1-positive lysosomes decreased in Con-shRNA-transfected HT22 neurons exposed to OGD/R or CQ. In HCN2-shRNA-transfected HT22 neurons, the percentage of LC3-positive puncta that co-localized with LAMP-1-positive lysosomes increased under OGD/R; however, the percentage was significantly decreased by the addition of CQ to HCN2-shRNA-transfected HT22 neurons. The present results demonstrated that blockade of HCN2 channels provides neuroprotection against OGD/R and TGCI by accelerating autophagic degradation attributable to the promotion of autophagosome and lysosome fusion.

Abstract
Picophytoplankton (<3 μm), comprising picocyanobacteria (PCY) and photosynthetic picoeukaryotes (PPEs), are considerably important in the material circulation and energy flow of aquatic ecosystems. To explore the temporal and spatial variation patterns of picophytoplankton and their correlations with environmental factors in lotic Yangtze-connected lakes, field in-situ investigations were performed on a monthly basis during the wet season (May to August) in 2019 in East Lake Dongting, a Yangtze-connected lake. The results indicated that both the Chla biomass and abundances of picophytoplankton exhibited significant spatial and temporal variability (P<0.05). The picophytoplankton Chla biomass showed an average concentration of 8.52 μg·L-1 and accounted for 41.6% to total phytoplankton on an average. From May to August, Chla biomass of picophytoplankton kept increasing with increasing temperature, especially in the north and south of the lake, and it was the lowest in the east of the lake. PCY dominated picophytoplankton abundance in East Lake Dongting and was 3.4 times the abundance of PPEs on an average. Similar spatial and temporal variation patterns were observed between PCY and PPEs. The abundances of PCY and PPEs both increased first and then decreased during the wet season. Spatially, picophytoplankton showed a trend to migrate from the northern lake to the southern lake from May to July, and the abundance significantly declined in August and peaked mainly in the north of the lake. The analysis results showed that picophytoplankton in East Lake Dongting exhibited significant spatial and temporal variability during the wet season; the water level and N:P ratio were determined to be the most important factors explaining the variation of the abundance proportion of PCY and PPEs.

Abstract
Age-dependent loss of hypothalamic neural stem cells (htNSCs) is important for the pathological consequences of aging; however, it is unclear what drives the senescence of htNSCs. Here, we report that a long non-coding RNA, Hnscr, is abundantly expressed in the htNSCs of young mice but decreases markedly in middle-aged mice. We show that depletion of Hnscr is sufficient to drive the senescence of htNSCs and aging-like phenotypes in mice. Mechanistically, Hnscr binds to Y-box protein 1 (YB-1) to prevent its degradation and thus the attenuation of transcription of the senescence marker gene p16INK4A. Through molecular docking, we discovered that a naturally occurring small compound, theaflavin 3-gallate, can mimic the activity of Hnscr. Treatment of middle-aged mice with theaflavin 3-gallate reduced the senescence of htNSCs while improving aging-associated pathology. These results point to a mediator of the aging process and one that can be pharmacologically targeted to improve aging-related outcomes.

Abstract
Objectives CD31hiEMCNhi vessels (CD31, also known as PECAM1 [platelet and endothelial cell adhesion molecule 1]; EMCN, endomucin), which are strongly positive for CD31 and endomucin, couple angiogenesis and osteogenesis. However, the role of CD31hiEMCNhi vessels in bone regeneration remains unknown. In the present study, we investigated the role of CD31hiEMCNhi vessels in the process of bone regeneration. Materials and Methods We used endothelial‐specific Krüppel like factor 3 (Klf3) knockout mice and ophiopogonin D treatment to interfere with CD31hiEMCNhi vessel formation. We constructed a bone regeneration model by surgical ablation of the trabecular bone. Immunofluorescence and micro‐computed tomography (CT) were used to detect CD31hiEMCNhi vessels and bone formation. Results CD31hiEMCNhi vessels participate in the process of bone regeneration, such that endothelial‐specific Klf3 knockout mice showed increased CD31hiEMCNhi vessels and osteoprogenitors in the bone regeneration area, and further accelerated bone formation. We also demonstrated that the natural compound, ophiopogonin D, acts as a KLF3 inhibitor to promote vessels formation both in vitro and in vivo. Administration of ophiopogonin D increased the abundance of CD31hiEmcnhi vessels and accelerated bone healing. Conclusions Our findings confirmed the important role of CD31hiEmcnhi vessels in bone regeneration and provided a new target to treat bone fracture or promote bone regeneration.

Abstract
We first report three reliable analytical expressions of the entropy, enthalpy and Gibbs free energy of carbon dioxide (CO2) and perform predictions of these three thermodynamic quantities on the basis of the proposed analytical expressions and in terms of experimental values of five molecular constants for CO2. The average relative deviations of the calculated values from the National Institute of Standards and Technology database over the temperature range from 300 to 6000 K are merely 0.053, 0.95, and 0.070%, respectively, for the entropy, enthalpy, and Gibbs free energy. The present predictive expressions are away from the utilization of plenty of experimental spectroscopy data and are applicable to treat CO2 capture and storage processes.

Abstract
The authors report a mutation in the long noncoding RNA Reg1cp that induces osteogenesis via vascular induction in humans. This mutation affects angiogenesis by blocking Klf3’s repressing activity. The Klf3 antagonist Ophiopogonin D could promote CD31hiEmcnhi vessel formation and osteogenesis in osteoporosis mice. High bone mass (HBM) is usually caused by gene mutations, and its mechanism remains unclear. In the present study, we identified a novel mutation in the long noncoding RNA Reg1cp that is associated with HBM. Subsequent analysis in 1,465 Chinese subjects revealed that heterozygous Reg1cp individuals had higher bone density compared with subjects with WT Reg1cp. Mutant Reg1cp increased the formation of the CD31hiEmcnhi endothelium in the bone marrow, which stimulated angiogenesis during osteogenesis. Mechanistically, mutant Reg1cp directly binds to Krüppel-like factor 3 (KLF3) to inhibit its activity. Mice depleted of Klf3 in endothelial cells showed a high abundance of CD31hiEmcnhi vessels and increased bone mass. Notably, we identified a natural compound, Ophiopogonin D, which functions as a KLF3 inhibitor. Administration of Ophiopogonin D increased the abundance of CD31hiEmcnhi vessels and bone formation. Our findings revealed a specific mutation in lncRNA Reg1cp that is involved in the pathogenesis of HBM and provides a new target to treat osteoporosis.

Abstract
Objective: To analyze the influence of simulation mouse use motion under different wrist forcing postures on median nerve, tendons and ligaments in the carpal tunnel. Methods: From June to November in 2017, a total of 49 healthy volunteers [aged from 18 to 27 years, 24 males (48 cases of hands) and 25 females (50 cases of hands)] were selected in the Institute of Digitized Medicine and First Affiliated Hospital of Wenzhou Medical University.Three hand postures of the volunteers were simultaneously and continuously measured by using LOGIQ E9 ultrasonic diagnostic apparatus and Zebris foot pressure distribution measurement system.Seventeen parameters of nerves, tendons and ligaments in carpal tunnel were observed under natural (0 N), and two forced (25 and 50 N) states.Double factor variance analysis was performed with generalized estimating equation (GEE). Results: With increasing pressure (0, 25 and 50 N) of hand postures, the distance between median nerve and transverse carpal ligament were all less than 0.2 cm.The differences in both the distance between median nerve and flexor pollicis longus under the hand pressure changes or under the hand posture changes and the top angle of a triangle composed of median nerve, flexor pollicis longus and flexor digitorum superficialis group under the hand pressure changes or under the hand posture changes were all significant under the GEE analysis (all P<0.01). There were no significant changes in all other structural parameters in the carpal tunnel with the increasing of hand pressure (all P>0.05). Conclusions: The influence of the transverse carpal ligament to the median nerve belongs to the mechanism of pressure-induced irritation damage.The influence of flexor pollicis longus to median nerve belongs to the mechanism of tension-induced irritation damage.The influence of flexor digitorum superficialis to median nerve belongs to the mechanism of mixed shear irritation damage.

Abstract
Bone marrow mesenchymal stem cells (BMSCs) exhibit an age-related lineage switch between osteogenic and adipogenic fates, which contributes to bone loss and adiposity. Here we identified a long noncoding RNA, Bmncr, which regulated the fate of BMSCs during aging. Mice depleted of Bmncr (Bmncr-KO) showed decreased bone mass and increased bone marrow adiposity, whereas transgenic overexpression of Bmncr (Bmncr-Tg) alleviated bone loss and bone marrow fat accumulation. Bmncr regulated the osteogenic niche of BMSCs by maintaining extracellular matrix protein fibromodulin (FMOD) and activation of the BMP2 pathway. Bmncr affected local 3D chromatin structure and transcription of Fmod. The absence of Fmod modified the bone phenotype of Bmncr-Tg mice. Further analysis revealed that Bmncr would serve as a scaffold to facilitate the interaction of TAZ and ABL, and thus facilitate the assembly of the TAZ and RUNX2/PPARG transcriptional complex, promoting osteogenesis and inhibiting adipogenesis. Adeno-associated viral-mediated overexpression of Taz in osteoprogenitors alleviated bone loss and marrow fat accumulation in Bmncr-KO mice. Furthermore, restoring BMNCR levels in human BMSCs reversed the age-related switch between osteoblast and adipocyte differentiation. Our findings indicate that Bmncr is a key regulator of the age-related osteogenic niche alteration and cell fate switch of BMSCs.

Abstract
Electrolyte gating is a powerful means for tuning the carrier density and exploring the resultant modulation of novel properties on solid surfaces. However, the mechanism, especially its effect on the oxygen migration and electrostatic charging at the oxide heterostructures, is still unclear. Here we explore the electrolyte gating on oxygen-deficient interfaces between SrTiO_{3} (STO) crystals and LaAlO_{3} (LAO) overlayer through the measurements of electrical transport, x-ray absorption spectroscopy, and photoluminescence spectra. We found that oxygen vacancies (O_{vac}) were filled selectively and irreversibly after gating due to oxygen electromigration at the amorphous LAO/STO interface, resulting in a reconstruction of its interfacial band structure. Because of the filling of O_{vac}, the amorphous interface also showed an enhanced electron mobility and quantum oscillation of the conductance. Further, the filling effect could be controlled by the degree of the crystallinity of the LAO overlayer by varying the growth temperatures. Our results reveal the different effects induced by electrolyte gating, providing further clues to understand the mechanism of electrolyte gating on buried interfaces and also opening a new avenue for constructing high-mobility oxide interfaces.

Abstract
BACKGROUND AND STUDY AIMS To investigate the relationship among fibrotic, haemostatic and endotoxic changes in patients with different degrees of liver cirrhosis. PATIENTS AND METHODS Liver fibrotic markers, including hyaluronic acid (HA), Ccollagen IV (Col-IV), laminin (LN), and N-terminal pro-peptide of collagen type III (PIIINP), were determined by radioimmunoassay. A series of haemostatic tests, including prothrombin time (PT), international normalized ratio, activated partial thromboplastin time, antithrombin-III, thrombin time, fibrinogen, fibrin(ogen) degradation product and D-dimer were determined using an automatic coagulation analyszer. Plasma levels of endotoxin were detected quantitatively using an endotoxin detection kit. Correlation analysis of the data was performed. RESULTS Based on Child-Pugh classification, statistically significant differences in fibrotic markers and haemostatic parameters were found in 249 patients with liver cirrhosis, while no significant differences in endotoxin levels were observed. Based on ascites classification, statistically significant differences in fibrotic markers (such as HA, Col-IV and PIIINP, except for LN) and haemostatic parameters were found. As for endotoxin levels, there were significant differences between the ascites, spontaneous bacterial peritonitis (SBP) and no-ascites groups, while no significant differences were observed between the ascites and SBP groups. Correlation analysis demonstrated some correlation among fibrotic markers, haemostatic parameters and endotoxin. CONCLUSIONS A close relationship exists between the severity of cirrhosis and fibrotic changes, as well as haemostatic changes. Endotoxin may be an important contributing factor to the development of ascites in cirrhosis. Some correlation may exist between fibrosis, haemostatic and endotoxin.

Abstract
Complex-oxide materials exhibit physical properties that involve the interplay of charge and spin degrees of freedom. However, an ambipolar oxide that is able to exhibit both electron-doped and hole-doped ferromagnetism in the same material has proved elusive. Here we report ambipolar ferromagnetism in LaMnO3, with electron-hole asymmetry of the ferromagnetic order. Starting from an undoped atomically thin LaMnO3 film, we electrostatically dope the material with electrons or holes according to the polarity of a voltage applied across an ionic liquid gate. Magnetotransport characterization reveals that an increase of either electron-doping or hole-doping induced ferromagnetic order in this antiferromagnetic compound, and leads to an insulator-to-metal transition with colossal magnetoresistance showing electron-hole asymmetry. These findings are supported by density functional theory calculations, showing that strengthening of the inter-plane ferromagnetic exchange interaction is the origin of the ambipolar ferromagnetism. The result raises the prospect of exploiting ambipolar magnetic functionality in strongly correlated electron systems.

Abstract
Although many members encoding different ammonium- and nitrate-transporters (AMTs, NRTs) were identified and functionally characterized from several plant species, little is known about molecular components for [Formula: see text]- and [Formula: see text] acquisition/transport in tobacco, which is often used as a plant model for biological studies besides its agricultural and industrial interest. We reported here the first molecular identification in tobacco (Nicotiana tabacum) of nine AMTs and four NRTs, which are respectively divided into four (AMT1/2/3/4) and two (NRT1/2) clusters and whose functionalities were preliminarily evidenced by heterologous functional-complementation in yeast or Arabidopsis. Tissue-specific transcriptional profiling by qPCR revealed that NtAMT1.1/NRT1.1 mRNA occurred widely in leaves, flower organs and roots; only NtAMT1.1/1.3/2.1NRT1.2/2.2 were strongly transcribed in the aged leaves, implying their dominant roles in N-remobilization from source/senescent tissues. N-dependent expression analysis showed a marked upregulation of NtAMT1.1 in the roots by N-starvation and resupply with N including [Formula: see text], suggesting a predominant action of NtAMT1.1 in [Formula: see text] uptake/transport whenever required. The obvious leaf-expression of other NtAMTs e.g., AMT1.2 responsive to N indicates a major place, where they may play transport roles associated with plant N-status and ([Formula: see text]-)N movement within aerial-parts. The preferentially root-specific transcription of NtNRT1.1/1.2/2.1 responsive to N argues their importance for root [Formula: see text] uptake and even sensing in root systems. Moreover, of all NtAMTs/NRTs, only NtAMT1.1/NRT1.1/1.2 showed their root-expression alteration in a typical diurnal-oscillation pattern, reflecting likely their significant roles in root N-acquisition regulated by internal N-demand influenced by diurnal-dependent assimilation and translocation of carbohydrates from shoots. This suggestion could be supported at least in part by sucrose- and MSX-affected transcriptional-regulation of NtNRT1.1/1.2. Thus, present data provide valuable molecular bases for the existence of AMTs/NRTs in tobacco, promoting a deeper understanding of their biological functions.

Abstract
OBJECTIVE To investigate the incidence of peri-anesthesia allergy in a tertiary teaching hospital. METHODS This was a retrospective cohort study. Patients who received anesthesia in operation rooms at Peking University First Hospital from January 2012 to April 2017 were enrolled. Researchers reviewed all the patients' electronic records and screened suspect allergy cases. Allergy was diagnosed according to the definition in Consensus on Management of Perioperative Allergy (China) and Scandinavian Clinical Practice Guidelines on the Diagnosis, Management and Follow-up of Anaphylaxis during Anesthesia. After obtaining the electronic records, two researchers began to screen and supplement missing data according medical records independently, then they checked out each other's data. The final data were reviewed by another two researchers. We collected the patients' basic characteristics, surgery type, anesthesia type, peri-anesthesia use of drugs, prognosis and other data. Univariate logistic regression was employed to screen potential factors of allergy. Factors with statistical significance (P<0.05) in univariate Logistic regression were entered into multivariate Logistic regression to identify independent risk factors of allergy. RESULTS In the study, 106 074 patients entered final statistic analysis. The incidence of peri-anesthesia allergy was about 1.5/1 000 (156/106 074). The incidence of Grades I, II and III allergy was 64.1% (100/156), 30.1% (47/156), and 5.8% (9/156) respectively. Multivariate logistic regression showed 5 independent risk factors of allergy including history of allergy (OR=6.836, 95%CI: 4.461-10.474, P<0.001), intraoperative use of sufentanil (OR=1.993, 95%CI: 1.228-3.232, P=0.005), intraoperative use of cis-atracuronium (OR=2.495, 95%CI: 1.599-3.893, P<0.001), intraoperative infusion of antibiotics (OR=2.005, 95%CI: 1.375-2.924, P<0.001) and frozen fresh plasma (OR=3.055, 95%CI: 1.842-5.068, P<0.001). CONCLUSION The incidence of peri-anesthesia allergy is high and further attempt is needed to establish standard operation process of diagnosis and treatment of allergy.

Abstract
A 65-year-old man with no previous history of heart disease presented with cardiogenic shock. Acute right ventricular failure following extensive inferior wall myocardial infarction and complete atrioventricular block were noted and emergent angiography revealed insignificant coronary arterial stenosis. In view of the finding and absence of myocardial vasculitis, coronary artery spasm was implicated as the cause of myocardial infarction and complete atrioventricular block. After the reversal of the shock and successful angioplasty, the patient continued to take lercanidipine and had been angina-free during follow-up of 5 months. (Hong Kong j.emerg.med. 2013;20:396-399)

Abstract
Introduction We assessed whether a strategy using dynamic, internet-mediated, team-based case management could reduce the number of subsequent emergency department (ED) visits by frequent ED users. Methods Patients who attended the ED three or more times within 72 hours in June 2010 were identified. These cases were divided into the pain management or chronic disease group according to their chief complaint. Patients were assessed by expert panels, and initial care plans were developed and posted on an internal website. Thereafter, each emergency physician could follow or adjust the care plans dynamically via the internal website according to the patient's condition and use the website to communicate results. Care plans were revised by the team according to the patient's clinical situation as it changed. Patient ED visits over the subsequent six months were monitored. Results Fourteen cases were enrolled in the study, seven in each group. The mean number of visits per patient per month in the pain management and chronic disease groups decreased from 14.9 to 5.79 (p=0.031) and 6.1 to 2.9 (p<0.001) visits per month after the intervention, respectively. The overall mean number of visits per patient per month decreased from 10.5 to 4.36 (p=0.004), a decrease of 6.14 visits (58.27%). Conclusions Dynamic internet-mediated team-based case management may help to reduce subsequent visits in patients who frequently visit the ED. (Hong Kong j.emerg.med. 2014;21:161-166)

Abstract
Objective: To compare the long term safety and efficacy of the novel abluminal groove-filled biodegradable polymer sirolimus-eluting stent(Firehawk stent) and permanent polymer coating everolimus eluting stent(Xience V stent) for the treatment of coronary de novo lesions. Methods: This prospective, multi-center, non-inferiority, randomized control trial(TARGETⅠ trial) was performed between August 2010 and April 2011, a total of 460 patients with primary, de novo, single vessel and single coronary lesion from 16 medical centers were enrolled. The diameter stenosis of target lesion was ≥70%, and lesion length was≤24 mm. The patients were randomly assigned to treatment with Firehawk stent (Firehawk stent group) or Xience V stent (Xience V stent group) groups by a web-based allocation system and was stratified by center. The late lumen loss after 9 months, target lesion failure (TLF) which was a composite of cardiac death, target vessel myocardial infarction, or ischemia driven target lesion revascularization, patient-oriented composite endpoint (PoCE) which was a composite of all cause death, all cause myocardial infarction, or any revascularization, and stent thrombosis after 5 years were compared between the two groups. Results: (1) There were 2 patients without stent implantation dropped out of this trial. There were 227 patients in Firehawk stent group, and 231 patients in Xience V stent group. The baseline characteristics were similar between the two groups(all P>0.05). (2) The 9 months late lumen loss in Firehawk stent group was non-inferior to that in Xience V stent group ((0.13±0.24)mm vs. (0.13±0.18)mm, P=0.94). (3) A total of 442 (96.5%) patients completed 5 years clinical follow-up. There were no significant differences on 5-year TLF rate (6.0%(13/217) vs. 6.7% (15/225), P=0.77) and PoCE rate (12.0%(26/217) vs. 17.8% (40/225), P=0.09) between the Firehawk stent group and Xience V stent group. (4) Kaplan-Meier analysis showed that TLF rates between 1-5 years were similar in Firehawk stent group and Xience V stent group (5.7% and 6.6% respectively, HR=0.88, 95%CI 0.42-1.84, P=0.72). Land-Mark analysis showed that TLF rates bewteen 1-5 years were similar in Firehawk stent group and Xience V stent group (3.6% and 4.4% respectively, HR=0.83, 95%CI 0.34-2.00, P=0.67). Kaplan-Meier analysis showed that PoCE rates between 1-5 years were also similar in Firehawk stent group and Xience V stent group (11.4% and 17.3% respectively, HR=0.64, 95%CI 0.39-1.04, P=0.07). Land-Mark analysis showed that PoCE rates after 5 years were similar in Firehawk stent group and Xience V stent group (8.4% and 10.0% respectively, HR=0.66, 95%CI 0.40-1.10, P=0.11). (5) No stent thrombosis was documented in Firehawk stent group during the 5 years follow-up period, and there was 1 case of stent thrombosis in Xience V stent group after 3 years of stent implantation. Conclusion: TARGETⅠ trial results of 5 years follow up indicate the novel Firehawk stent have a durable safety and efficacy profile which is comparable to the Xience V stent in treating patients with single de novo coronary lesion.

Abstract
Although biological functions of ammonium (NH4+) transporters (AMTs) have been intensively studied in many plant species, little is known about molecular bases responsible for NH4+ movement in tobacco. Here, we reported the identification and functional characterization of a putative NH4+ transporter NtAMT1.3 from tobacco (Nicotiana tabacum). Analysis in silico showed that NtAMT1.3 encoded an integral membrane protein containing 464 amino acid residues and exhibiting 10 predicted transmembrane α-helices. Heterologous functionality study demonstrated that NtAMT1.3 expression facilitated NH4+ entry across plasma membrane of NH4+-uptake defective yeast and Arabidopsis qko mutant, allowing a restored growth of both yeast and Arabidopsis mutant on low NH4+. qPCR assay revealed that NtAMT1.3 was expressed in both roots and leaves and significantly up-regulated by nitrogen starvation and resupply of its putative substrate NH4+ and even nitrate, suggesting that NtAMT1.3 should represent a nitrogen-responsive gene. Critically, constitutive overexpression of NtAMT1.3 in tobacco per se improved obviously the growth of transgenic plants on NH4+ and enhanced leaf nitrogen (15% more) accumulation, consistent with observation of 35% more NH4+ uptake by the roots of transgenic lines in 20min root-influx test. Together with data showing its plasma membrane localization and saturated transport nature with Km of about 50μM for NH4+, we suggest that NtAMT1.3 acts an active NH4+ transporter that plays a significant role in NH4+ acquisition and utilization in tobacco.

Abstract
Emergent phenomena at polar-nonpolar oxide interfaces have been studied intensely in pursuit of next-generation oxide electronics and spintronics. Here we report the disentanglement of critical thicknesses for electron reconstruction and the emergence of ferromagnetism in polar-mismatched LaMnO_{3}/SrTiO_{3} (001) heterostructures. Using a combination of element-specific x-ray absorption spectroscopy and dichroism, and first-principles calculations, interfacial electron accumulation, and ferromagnetism have been observed within the polar, antiferromagnetic insulator LaMnO_{3}. Our results show that the critical thickness for the onset of electron accumulation is as thin as 2 unit cells (UC), significantly thinner than the observed critical thickness for ferromagnetism of 5 UC. The absence of ferromagnetism below 5 UC is likely induced by electron overaccumulation. In turn, by controlling the doping of the LaMnO_{3}, we are able to neutralize the excessive electrons from the polar mismatch in ultrathin LaMnO_{3} films and thus enable ferromagnetism in films as thin as 3 UC, extending the limits of our ability to synthesize and tailor emergent phenomena at interfaces and demonstrating manipulation of the electronic and magnetic structures of materials at the shortest length scales.

Abstract
A specific bone vessel subtype, strongly positive for CD31 and endomucin (CD31hiEmcnhi), is identified as coupling angiogenesis and osteogenesis. The abundance of type CD31hiEmcnhi vessels decrease during ageing. Here we show that expression of the miR-497∼195 cluster is high in CD31hiEmcnhi endothelium but gradually decreases during ageing. Mice with depletion of miR-497∼195 in endothelial cells show fewer CD31hiEmcnhi vessels and lower bone mass. Conversely, transgenic overexpression of miR-497∼195 in murine endothelium alleviates age-related reduction of type CD31hiEmcnhi vessels and bone loss. miR-497∼195 cluster maintains the endothelial Notch activity and HIF-1α stability via targeting F-box and WD-40 domain protein (Fbxw7) and Prolyl 4-hydroxylase possessing a transmembrane domain (P4HTM) respectively. Notably, endothelialium-specific activation of miR-195 by intravenous injection of aptamer-agomiR-195 stimulates CD31hiEmcnhi vessel and bone formation in aged mice. Together, our study indicates that miR-497∼195 regulates angiogenesis coupled with osteogenesis and may represent a potential therapeutic target for age-related osteoporosis. H-type endothelium, defined by the high expression of CD31 and endomucin, is found in the bone where it promotes angiogenesis and osteogensis. Here Yang et al. show that the miR-497∼195 cluster regulates the generation and maintenance of the H-type endothelium by controlling the levels of Notch regulator Fbxw7 and the HIF regulator P4HTM.

Abstract
4077 Background: Napabucasin, a first-in-class cancer stemness inhibitor in clinical development, suppresses cancer stemness by targeting STAT3-driven gene transcription. Amcasertib targets multiple serine threonine stemness kinases and inhibits Nanog and other cancer stemness pathways. Preclinically, potent and broad-spectrum anti-cancer activity was observed in vitro and in vivo, alone and in combination with sorafenib. Methods: A phase Ib/II open-label, multi-center study in adult patients with advanced HCC who have not received prior systemic chemotherapy was performed to determine the safety, tolerability, and recommended Phase II dose (RP2D) ,according to the criteria for DLT and for dose-escalation of Napabucasin (Arm 1), administered at 160 mg BID (dose level I) and at 240 mg BID (dose level II) in combination with sorafenib and of Amcasertib (Arm 2), administered at 100 mg QD (dose level I) and at 200 mg QD (dose level II) in combination with sorafenib. Results: 20 pts were enrolled, 10 in Arm 1 and 10 in Arm 2. 12 patients were evaluable for DLT determination; 2 pts d/c prior to starting protocol treatment; 11 pts received evaluation by RECIST, 6 pts in Arm 1 and 5 pts in Arm 2. The safety profile was consistent with that of each agent as monotherapy and most common AEs were attributed to (Sor) and included rash, PPE, grade 1/2 diarrhea, nausea, abdominal cramps, and vomiting. No signs of drug-drug interactions were observed in pharmacokinetics. Among all patients who received RECIST evaluation, Disease Control Rate (DCR=CR+PR+SD) for Arm 1 was 100% (6/6pts) and 100% (5/5pts) for Arm 2. DCR in ITT Arm 1 population was 67% and 50% in Arm 2. Median OS is not yet reached. Conclusions: In this phase Ib study, RP2D were determined for napabucasin and amcasertib to be safely combined with sorafenib at full dose, showing encouraging anti-tumor activity in patients with HCC who have not received prior systemic chemotherapy. A randomized phase II is schedule to start. Clinical trial information: NCD02279719. [Table: see text]

Abstract
e13525 Background: Napabucasin, a first-in-class cancer stemness inhibitor in clinical development, suppresses cancer stemness by targeting STAT3-driven gene transcription. Pre-clinically, potent and broad-spectrum anti-cancer activity was observed in vitro and in vivo, alone and in combination with other agents. PK studies demonstrated napabucasin penetration in the murine orthotopic GBM model. Methods: A phase Ib/II open-label, multi-center study in pts with GBM at first recurrence who have not received bevacizumab, was performed to determine safety and preliminary activity of napabucasin administered orally at 480mg BID po in combination with TMZ 150mg/m²/day po; days 1 through 5 of each 28 day cycle, until disease progression or unacceptable toxicity. A 6-patient safety cohort was planned to evaluate the occurrence of DLT during the first 28 days of combination treatment with napabucasin and TMZ. 4 additional patients have been enrolled under the RP2D expansion phase. Results: 11 pts have been enrolled to date; no DLT was observed in the safety cohort and the RP2D of the combination is 480 mg BID for napabucasin. The safety profile was consistent with that of each agent as monotherapy and most common AEs included grade 1/2 diarrhea, nausea, abdominal cramps, and vomiting. Two patients requested to withdraw treatment due to concurrent conditions and AE s. 9 patients were evaluable by RANO; Disease Control Rate was observed in 5 patients (55.5%) of which 4 achieved PR (44.4%) and 1 achieved SD (11.1%). The Overall response rate was 44.4% in the evaluable patients. Conclusions: This phase Ib/II study demonstrated that napabucasin at 480 mg BID can be safely combined with temozolomide at full dose and showed encouraging anti-tumor activity in patients with recurrent Glioblastoma.

Abstract
Nerve growth factor (NGF), which is required for the survival and differentiation of the nervous system, has been proved to play important roles in male reproductive physiology. Several studies have focused on the roles of NGF in the testes. However, no study has reported on the mechanism of paracrine and autocrine actions of NGF in Sertoli cells. This study showed that NGF stimulated mitochondrial activity and biogenesis in TM4 Sertoli cells. Moreover, our results demonstrated that peroxisome proliferator-activated receptor-gamma coactivator-1α is a possible downstream key target of the NGF signalling pathway. In a 3-nitropropionic acid cell model, NGF treatment attenuated mitochondrial activity defect and depolarisation. This NGF-triggered signalling may help in discovering new therapeutic targets for certain male infertility disorders.
