Abstract
Triple-negative breast cancer (TNBC) is insensitive to conventional therapy due to its highly invasive nature resulting in poor therapeutic outcomes. Recent studies have shown multiple genes associated with ferroptosis in TNBC, suggesting an opportunity for ferroptosis-based treatment of TNBC. However, the efficiency of present ferroptosis agents for cancer is greatly restricted due to lack of specificity and low intracellular levels of H2O2 in cancer cells. Herein, we report a nano-theranostic platform consisting of gold (Au)-iron oxide (Fe3O4) Janus nanoparticles (GION@RGD) that effectively enhances the tumor-specific Fenton reaction through utilization of near-infrared (NIR) lasers, resulting in the generation of substantial quantities of toxic hydroxyl radicals (•OH). Specifically, Au nanoparticles (NPs) converted NIR light energy into thermal energy, inducing generation of abundant intracellular H2O2, thereby enhancing the iron-induced Fenton reaction. The generated •OH not only lead to apoptosis of malignant tumor cells but also induce the accumulation of lipid peroxides, causing ferroptosis of tumor cells. After functionalizing with the activity-targeting ligand RGD (Arg-Gly-Asp), precise synergistic treatment of TNBC was achieved in vivo under the guidance of Fe3O4 enhanced T2-weighted magnetic resonance imaging (MRI). This synergistic treatment strategy of NIR-enhanced ferroptosis holds promise for the treatment of TNBC.

Abstract
Ferroptosis has received increasing attention as a novel nonapoptotic programmed death. Recently, iron-based nanomaterials have been extensively exploited for efficient tumor ferroptosis therapy, as they directly release high concentrations of iron and increase intracellular reactive oxygen species levels. Breast cancer is one of the commonest malignant tumors in women; inhibiting breast cancer cell proliferation through activating the ferroptosis pathway could be a potential new target for patient treatment. Here, we briefly introduce the background of ferroptosis and systematically review the current cancer therapeutic strategies based on iron-based ferroptosis inducers. Finally, we summarize the advantages of these various ferroptosis inducers and shed light on future perspectives. This review aims to provide better guidance for the development of iron-based nanomaterial ferroptosis inducers.

Abstract
Activating the lattice oxygen in the catalysts to participate in the oxygen evolution reaction (OER), which can break the scaling relation-induced overpotential limitation (> 0.37 V) of the adsorbate evolution mechanism, has emerged as a new and highly effective guide to accelerate the OER. However, how to increase the lattice oxygen participation of catalysts during OER remains a major challenge. Herein, P-incorporation induced enhancement of lattice oxygen participation in double perovskite LaNi0.58 Fe0.38 P0.07 O3-σ (PLNFO) is studied. P-incorporation is found to be crucial for enhancing the OER activity. The current density reaches 1.35 mA cmECSA -2 at 1.63 V (vs RHE), achieving a sixfold increase in intrinsic activity. Experimental evidences confirm the dominant lattice oxygen participation mechanism (LOM) for OER pathway on PLNFO. Further electronic structures reveal that P-incorporation shifts the O p-band center by 0.7 eV toward the Fermi level, making the states near the Fermi level more O p character, thus facilitating LOM and fast OER kinetics. This work offers a possible method to develop high-performance double perovskite OER catalysts for electrochemical water splitting.

Abstract
PURPOSE/OBJECTIVE(S) To study the feasibility and safety for patients with high-risk (HR) and very high-risk (VHR) prostate cancer treated with adaptive ultra-hypofractionated whole-pelvic radiotherapy (UHF-WPRT) on 1.5 magnetic resonance (MR)-Linac. MATERIALS/METHODS Sevenpatients with clinical stage T3a-4N0-1M0-1c consecutively treated with UHF-WPRT on a 1.5-T MR-Linac were recruited prospectively in a phase II trial (NCT05183074, ChiCTR2000033382). A 36.25 Gy dose in five fractions was delivered every other day with a boost of 40 Gy to the whole prostate, as well as 25 Gy to whole pelvic nodal area with a concomitant boost of 35 Gy to metastatic regional nodes. To estimate the delivered dose, we collected data by 3D-MR for the following stages: pre-MR, position verification-MR (PV-MR) in the Adapt-To-Shape (ATS) workflow, and 3D-MR during the beam-on phase (Bn-MR) and at the end of RT (post-MR). The target and organ-at-risk contours in the PV-MR, Bn-MR, and post-MR stages were projected from the pre-MR data by deformable image registration and manually adapted by the physician, followed by dose recalculation for the ATS plan. The cumulative acute genitourinary (GU) and gastrointestinal (GI) toxicities were evaluated as per NCI-CTCAE 5.0 criteria. The primary endpoints were acute ≥grade 3 genitourinary (GU) and gastrointestinal (GI) toxicities during the first 3 months. RESULTS Overall, 133 MR scans were collected (35 pre-MR, 35 PV-MR, 31 Bn-MR and 32 post-MR scans). With a median on-couch time of 61 minutes, the mean prostate and pelvic planning target volume (PTV)-V95% of all scans was 96.98 ± 3.06% and 96.44 ± 2.85%, respectively. The corresponding mean prostate clinical target volume (CTV)-V100% was 99.89 ± 0.32%, 98.71 ± 1.90%, 97.77 ± 2.89%, and 98.56 ± 1.72%, and the mean pelvic CTV-V100% was 97.57% ± 3.70%, 96.54 ± 3.80%, 95.43 ± 4.31%, and 94.39 ± 4.47% on pre-MR, PV-MR, Bn-MR and post-MR scans, respectively. For the 4 patients with positive nodes, the mean V100% of metastatic regional nodes was 99.89 ± 0.81%. The median V29 Gy change in the rectal wall was -1% (-18%-20%). The V29 Gy of the rectal wall increased by >15% was observed in one scan. A slight increase in the high dose of bladder wall was noted due to gradual bladder growth during the workflow. With median follow-up time of 7.3 (4.6-12.2) months, all patients were followed-up for more than 3 months. No patient was observed with acute CTCAE grade 2 or more severe GU or GI toxicities (0%). CONCLUSION UHF-RT to prostate and pelvic with ATS workflow is well tolerated by patients with HR and VHR prostate cancer, with only mild GU and GI toxicities. The 3D-MR-based dosimetry analysis demonstrated clinically acceptable estimated dose coverage of target volumes during the beam-on period.

Abstract
OBJECTIVES Understanding iodine deficiency (ID) burdens and trends in Asia can help guide effective intervention strategies. This study aims to report the incidence, prevalence, and disability-adjusted life years (DALYs) of ID in 48 Asian countries during the period 1990-2019. STUDY DESIGN Data on ID were retrieved from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 and estimated by age, sex, geographical region, and sociodemographic index (SDI). METHODS The estimated annual percentage change (EAPC) was calculated to evaluate the changing trend of age-standardized incidence rate (ASIR), age-standardized prevalence rate (ASPR), and age-standardized DALYs rate (ASDR) related to ID during the period 1990-2019. RESULTS In Asia, there were 126,983,965.8 cases with 5,466,213.1 new incidence and 1,765,995.5 DALYs of ID in 2019. Between 1999 and 2019, the EAPC in ASIR, ASPR and ASDR were -0.6 (95% confidence interval [CI], -0.8 to -0.4), -0.9 (95% CI, -1.2 to -0.7), and -1.6 (95% CI, -1.8 to -1.5), respectively. Malaysia charted the largest decrease in ASIR, ASPR, and ASDR (82.4%, 85.3%, and 80.9% separately), whereas the Philippines and Pakistan were the only two countries that witnessed an increase in ASIR and ASPR. ID burdens were more pronounced in women, countries located to the south of the Himalayas, and low-middle SDI regions. CONCLUSIONS The incidence, prevalence, and DALYs of ID in Asia substantially decreased from 1990 to 2019. Women and low-middle SDI countries have relatively high ID burdens. Governments need to pay constant attention to the implementation and monitoring of universal salt iodization.

Abstract
Intracerebral hemorrhage (ICH) is a non-traumatic hemorrhage caused by the rupture of blood vessels in the brain parenchyma, with an acute mortality rate of 30%‒40%. Currently, available treatment options that include surgery are not promising, and new approaches are urgently needed. Nanotechnology offers new prospects in ICH because of its unique benefits. In this review, we summarize the applications of various nanomaterials in ICH. Nanomaterials not only enhance the therapeutic effects of drugs as delivery carriers but also contribute to several facets after ICH such as repressing detrimental neuroinflammation, resisting oxidative stress, reducing cell death, and improving functional deficits.

Abstract
Zinc is one of the most abundant metal ions in the central nervous system (CNS), where it plays a crucial role in both physiological and pathological brain functions. Zinc promotes antioxidant effects, neurogenesis, and immune system responses. From neonatal brain development to the preservation and control of adult brain function, zinc is a vital homeostatic component of the CNS. Molecularly, zinc regulates gene expression with transcription factors and activates dozens of enzymes involved in neuronal metabolism. During development and in adulthood, zinc acts as a regulator of synaptic activity and neuronal plasticity at the cellular level. There are several neurological diseases that may be affected by changes in zinc status, and these include stroke, neurodegenerative diseases, traumatic brain injuries, and depression. Accordingly, zinc deficiency may result in declines in cognition and learning and an increase in oxidative stress, while zinc accumulation may lead to neurotoxicity and neuronal cell death. In this review, we explore the mechanisms of brain zinc balance, the role of zinc in neurological diseases, and strategies affecting zinc for the prevention and treatment of these diseases.

Abstract
Poor tumor delivery efficiency remains a significant challenge for the integrated nanoplatform for diagnosis and treatment. Nanotherapeutics capable of aggregation in response to the tumor microenvironment has received considerable attention because of its ability to enhance tumor delivery efficiency and accumulation. We prepared smart Au-Fe3O4 Janus nanoparticles (GIJ NPs) modified with mixed-charged ligands (3,4-dihydroxyhydrocinnamic acid [DHCA] and trimethylammonium dopamine [TMAD]). The obtained GIJ@DHCA-TMAD could be stable at the pH of the blood and normal tissues, but aggregated into larger particles in response to the tumor acidic microenvironment, leading to greatly enhanced accumulation in cancer cells. The hydrodynamic diameters of GIJ@DHCA-TMAD increased from 28.2 to 105.7 nm when the pH decreased from 7.4 to 5.5. Meanwhile, the T 2 magnetic resonance imaging (MRI) contrast capability, photoacoustic imaging (PAI) performance, and photothermal conversion efficiency of GIJ@DHCA-TMAD were also enhanced with increasing diameter. Tumor-specific enhanced MRI and PAI can precisely locate tumor boundaries and can be used to perform preliminary photothermal tumor ablation therapy: the pH-sensitive GIJ@DHCA-TMAD can be used in dual-mode, tumor-specific imaging-guided photothermal therapy to better meet the multiple requirements for in vivo applications.

Abstract
Organelles, including mitochondria (mito), lysosomes (lyso), endoplasmic reticulum (ER), Golgi apparatus (Golgi), and ribosome et al., play a vital role in maintaining the regular work of the cell. Viscosity is an essential parameter in the cellular microenvironment. Herein, four viscosity-sensitive near-infrared fluorescent probes DMPC, DEPC, DHDM and DHDV that can simultaneously target multiple organelles were synthesized. As the viscosity increased, the fluorescence intensity of the probes gradually increased due to the hindrance of the rotation of the carbon-carbon single bond. The fluorescence intensity of DHDV increased by about 453 times, and the fluorescence quantum yield also increased from 0.051 to 0.681. Cell experiments indicated the probes could simultaneously target four kinds of organelles, and the four probes could also track mitochondria with no dependence on membrane potential. Further experiments showed that the probes could detect viscosity changes in lyso and mito. In addition, the probes also demonstrated the advantages of low cytotoxicity, good anti-interference and stability, providing a simple and effective tool for studying the activity of organelles with changing viscosity signals.

Abstract
Stroke is the second highest cause of death globally, with an increasing incidence in developing countries. Intracerebral hemorrhage (ICH) accounts for 10-15% of all strokes. ICH is associated with poor neurological outcomes and high mortality due to the combination of primary and secondary injury. Fortunately, experimental therapies are available that may improve functional outcomes in patients with ICH. These therapies targeting secondary brain injury have attracted substantial attention in their translational potential. Here, we summarize recent advances in therapeutic strategies and directions for ICH and discuss the barriers and issues that need to be overcome to improve ICH prognosis.

Abstract
Abstract
Aim
Incisional hernias are common and can significantly impact a patient's quality of life. Traditionally, abdominal wall reconstruction (AWR) has been performed by general surgeons, or those with special interest, often working in isolation. However, there is increasing awareness of pre-optimisation, risk stratification, enhanced training, and personalising treatment using a wide range of techniques.
Methods & Results
For complex and higher-risk procedures, Multidisciplinary team (MDT) management is considered the standard of care for optimising outcomes. The lack of standardised protocols and clear evidence in AWR means that surgical management can vary greatly. This makes the MDT process even more important due to the complexity of the decision-making involved. We describe a successful MDT process for complex abdominal wall reconstruction at a tertiary referral centre. Patients are reviewed at weekly AWR meetings with a multidisciplinary team, which includes consultants, advanced clinical practitioners and trainees. This is an opportunity for objective risk stratification, radiological review and assessment of the patient's goals before preoptimization and operative planning. Prospective data is collected on all patients to allow for quality improvement and service development.
Conclusion
MDT management of abdominal wall hernia is gaining popularity but remains poorly established in most regions. The involvement of surgical colleagues and other specialists is crucial in developing this growing field of surgery. We hope to expand our team to include Radiologists and Nutritionists, with the possibility of extending to regional networks, as we continue to explore new techniques and methods in managing complex abdominal wall hernias.

Abstract
Chronic Post-operative Inguinal Pain (CPIP), is recognised as a long term condition and has a significant effect on patients’ quality of life. CPIP affects 18–30% of patients after an open inguinal hernia repair and 6% of patients after a laparoscopic inguinal hernia repair. CPIP result from several causes such as a pre-operative nerve lesion in other area of the body, an intra-operative nerve injury, or due to the intensity of acute post-operative inflammation and healing. a multidisciplinary clinic would be considered the best approach in order to assess patients’ pain and identify an individual management plan. This review allowed the team to choose which literature could be used to support the implementation of the clinical practice change.
Method
Literature searches were performed using PubMed and Embase databases were searched using key terms to include all related articles in the last ten years. three independent reviewers to choose included and excluded articles with two steps.
Results
Out of 25 articles found by the research, 8 articles included in this review including MDT about CPIP, meeting including criteria after the full articles reviewed. it was important to understand the nature and mechanisms of Chronic Post-operative inguinal hernia. several risk factors have been identified, which may be causing CPIP such as young age, recurrent inguinal hernia repair procedure and presence of pain before the procedure. Because of the complexity of CPIP, many authors concluding that a multidisciplinary approach should be considered the more appropriate method to ensure an effective and safe treatment. This include the need of regular follow up after an inguinal hernia repair to identify the chronic pain and establish an appropriate management plan.
Conclusions
Although the literature review enabled the team to gather useful information about the topic of the clinical practice change; it was evident that more researches and studies need to be completed in order to identify the safest and effective treatment for patients presenting with CPIP.

Abstract
Abstract
Hiatus hernia repair is a common operation with considerable variation in anatomy and technique. At present there are very few predictors of post-operative outcomes. Certain imaging characteristics may help in operative planning and predicting outcomes. The aim of this systematic review is to identify possible radiological markers associated with clinical outcomes in hiatal hernia repair.
A literature search was performed on the 7th December 2021 in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and Meta-analysis Of Observational Studies in Epidemiology guidelines of the PubMed, EMBASE and Cochrane Central Register of Controlled Trials using the following search term: ((hiatus) OR (paraesophageal)) AND (hernia) AND ((computed tomography) OR (CT) OR (imaging) OR (contrast) OR (swallow) OR (magnetic resonance) OR (ultrasound)). Inclusion criteria were studies (any design) testing the association of a radiological marker with any clinical outcome (either operative or non-operative) of hiatus hernia management. Exclusion criteria were case reports, non-English articles, non-human articles. Articles were screened by 2/3 authors on the basis of title and abstract. Full text articles were then retrieved for detailed analysis. Any disagreement was resolved by consultation with a 3rd/4th author.
Initial search identified 2768 papers, 9 of which were retrieved for full paper evaluation.
Preliminary review of the literature suggests that hernia recurrence is correlated with increased hernia size, although patients tend to be asymptomatic. Multidimensional CT can accurately measure hernia surface area and this could be useful in stratifying risk of re-herniation.

Abstract
Considering the increasing number of elderly in the world, this research aimed to investigate the effect of neuromuscular electrical stimulation (NMES) on changes in muscle mRNA abundance of a number of gene targets for improving the balance of the elderly. Twenty-six elderly undertook 30 minutes of quadriceps NMES (50 Hz, current at the limit of tolerance). Vastus lateralis muscle biopsies were obtained at rest immediately before and 24 hours after the intervention. The expression of 384 targeted mRNA transcripts was assessed by Real-time TaqMan PCR. A significant change in expression from baseline was determined using the ΔΔCT method with a false discovery rate (FDR) of <5%. The results showed that the biological functions of upregulated genes included muscle protein turnover, hypertrophy, inflammation, and muscle growth, while downregulated genes included mitochondrial and cell signaling functions. In general conclusion, it can be said that NMES can improve balance in the elderly. Therefore, considering the importance of balance in old people, it is suggested to use this method to improve the balance of the elderly.

Abstract
Anthocyanins and vitamins in black rice are the micronutrients vital to human health, both of which predominantly accumulate in the bran fraction. Some studies have demonstrated that black rice contains more vitamins compared with common white rice, indicating potential association between anthocyanin and vitamin accumulation. In this study, transcriptomes of pericarps collected from 27 black rice accessions and 49 white rice accessions at 10 days after flowering (DAF) were sequenced and analyzed. We identified 830 differentially expressed genes (DEGs) including 58 transcription factors (TFs) between black and white rice. Among 58 differentially expressed transcription factors, OsTTG1 was confirmed to be the one and only WD40 repeat protein regulating anthocyanin biosynthesis in the pericarp. Moreover, we identified 53 differentially expressed synthetic-related genes among 42 main synthesis enzymes in the biosynthesis pathway of seven vitamins including β-carotene, vitamin B1, vitamin B2, vitamin B5, vitamin B7, vitamin B9 and vitamin E. Collectively, our results provide valuable insights into the molecular mechanism of biosynthesis of anthocyanins and vitamins and the potential effect of anthocyanin biosynthesis on vitamin biosynthesis in black rice.

Abstract
Intracerebral hemorrhage (ICH) is a subtype of stroke that is characterized by high morbidity and mortality, for which clinical outcome remains poor. An extensive literature indicates that the release of ferrous iron from ruptured erythrocytes in the hematoma is a key pathogenic factor in ICH-induced brain injury. Deferoxamine is an FDA-approved iron chelator that has the capacity to penetrate the blood-brain barrier after systemic administration and binds to iron. Previous animal studies have shown that deferoxamine attenuates ICH-induced brain edema, neuronal death, and neurological deficits. This review summarizes recent progress of the mechanisms by which deferoxamine may alleviate ICH and discusses further studies on its clinical utility.

Abstract
The destruction of the blood-brain barrier (BBB) after intracerebral hemorrhage (ICH) is associated with poor prognosis. Modulation of sphingosine 1-phosphate receptor (S1PR) may improve outcomes from ICH. Ozanimod (RPC-1063) is a newly developed S1PR regulator which can selectively modulate type 1/5 sphingosine receptors. Here, we studied the impact of Ozanimod on neuroprotection in an experimental mouse model of ICH, induced by injecting collagenase type VII into the basal ganglia. Ozanimod was administered by gavage 2 h after surgery and once a day thereafter until sacrifice. The results demonstrate that Ozanimod treatment improved neurobehavioral deficits in mice and decreased weight loss after ICH. Ozanimod significantly reduced the density of activated microglia and infiltrated neutrophils in the perihematoma region. Furthermore, Ozanimod reduced hematoma volume and water content of the ICH brain. The results of TUNEL staining indicate that Ozanimod mitigated brain cell death. The quantitative data of Evans blue (EB) staining showed that Ozanimod reduced EB dye leakage. Overall, Ozanimod reduces the destruction of the BBB and exert neuroprotective roles following ICH in mice.

Abstract
Iron oxide nanoparticle (IONP) with unique magnetic property and high biocompatibility have been widely used as magnetic resonance imaging (MRI) contrast agent (CA) for long time. However, a review which comprehensively summarizes the recent development of IONP as traditional T2 CA and its new application for different modality of MRI, such as T1 imaging, simultaneous T2/T1 or MRI/other imaging modality, and as environment responsive CA is rare. This review starts with an investigation of direction on the development of high-performance MRI CA in both T2 and T1 modal based on quantum mechanical outer sphere and Solomon–Bloembergen–Morgan (SBM) theory. Recent rational attempts to increase the MRI contrast of IONP by adjusting the key parameters, including magnetization, size, effective radius, inhomogeneity of surrounding generated magnetic field, crystal phase, coordination number of water, electronic relaxation time, and surface modification are summarized. Besides the strategies to improve r2 or r1 values, strategies to increase the in vivo contrast efficiency of IONP have been reviewed from three different aspects, those are introducing second imaging modality to increase the imaging accuracy, endowing IONP with environment response capacity to elevate the signal difference between lesion and normal tissue, and optimizing the interface structure to improve the accumulation amount of IONP in lesion. This detailed review provides a deep understanding of recent researches on the development of high-performance IONP based MRI CAs. It is hoped to trigger deep thinking for design of next generation MRI CAs for early and accurate diagnosis. T2 contrast capacity of iron oxide nanoparticles (IONPs) could be improved based on quantum mechanical outer sphere theory. IONPs could be expand to be used as effective T1 CAs by improving q value, extending τs, and optimizing interface structure. Environment responsive MRI CAs have been developed to improve the diagnosis accuracy. Introducing other imaging contrast moiety into IONPs could increase the contrast efficiency. Optimizing in vivo behavior of IONPs have been proved to enlarge the signal difference between normal tissue and lesion.

However, the evolution of such coordinated network damage in patients with MS is unclear. We investigated whether short- and long-range structural connections sustained equal damage in early-stage MS. MATERIALS AND METHODS Sixteen patients with early-stage MS and 17 healthy controls were scanned by high-resolution, multishell diffusion imaging on 7T MR imaging and assessed cognitively. We investigated macrostructural properties in short- and long-range fibers and of microstructural metrics derived from 2 quantitative diffusion MR imaging models: DTI and neurite orientation dispersion and density imaging. RESULTS Patients had significant WM integrity damage-that is, higher radial diffusivity and a lower intracellular volume fraction in the focal WM lesions. Compared with the healthy controls, the patients had noticeable microstructure changes in both short- and long-range fibers, including increased radial diffusivity, mean diffusivity, and axial diffusivity. Z scores further indicated greater damage in the short-range fibers than in the long-range fibers. CONCLUSIONS Our findings demonstrate that more severe demyelination preceding axonal degeneration occurs in short-range connections but not in long-range connections in early-stage MS, suggesting the possibility that there are cortical lesions that are undetectable by current MR imaging.

Abstract
Since abdominal muscle training is one of the most important ways to treat rectal diastasis, it is necessary to design and provide appropriate exercises to treat this problem. One of the complementary methods to achieve higher intensity training is the use of electrical muscle stimulation along with voluntary activity, which causes maximum recall in muscle units. Therefore, in the current study, the effect of electrical stimulation followed by exercises was evaluated in postnatal diastasis recti abdominis via MMP2 gene expression. For this purpose, we studied on thirty-two women who had rectal diastasis for six months and were referred to a physiotherapy clinic by a gynecologist. They were divided into the control group (n=16) and the intervention group (n=16). The distance between the two blocks of the rectus abdominis muscle and the thickness of the abdominal muscles at rest was determined by ultrasound. In the intervention group, electrical stimulation and strengthening exercises of oblique muscles were performed for six weeks. The control group did not perform any specific exercises. After six weeks, another ultrasound was performed. The expression of the MMP2 gene was measured by the real-time PCR method. Comparison of the distance between the two blocks of rectus abdominis muscle (above the umbilicus and below the umbilicus) before and after six weeks showed that in the experimental group after intervention in both areas had a significant decrease (above the umbilicus = 0.001 and below the umbilicus P = 0.03), while this distance in the control group did not decrease significantly (p >0.05). Also, in the upper part of the umbilicus, the distance between the two rectus abdominis muscle blocks in two groups after the intervention showed a significant difference (p = 0.04). Evaluation of MMP2 gene expression showed that there was no significant difference between the two groups before the intervention (p >0.05). However, after the intervention, the expression of this gene decreased significantly in the intervention group (p = 0.007). In general, the present study results showed that electrical stimulation of abdominal muscles with strengthening exercises of internal and external oblique muscles could reduce rectal diastasis and increase the thickness of these muscles in people with rectal diastasis.

Abstract
We review the diagnosis, management and potential pitfalls of acute soft tissue injuries in the skeletally immature knee, including anterior cruciate ligament (ACL) injuries, meniscal injuries, patellar dislocation and patellofemoral instability (PFI). There has been an increasing incidence of such injuries in the paediatric population, and controversy remains regarding their treatment. We summarise evidence-based treatments for these injuries and discuss strategies to minimise complications as the child reaches skeletal maturity.

Abstract
Manganese oxide nanoparticles (NPs) have attracted increasing attention recently as contrast agents (CAs) for magnetic resonance imaging (MRI). However, the clinical translation and popularization of conventional MnO NPs are hampered by their relatively poor imaging performance. Herein, we report the construction of ultrasmall MnO NPs (USMnO) via a one-pot synthetic approach that show a much better capability of T1-weighted contrast enhancement for MRI (r1 = 15.6 ± 0.4 mM-1 s-1 at 0.5 T) than MnCl2 and conventional large-sized MnO NPs (MnO-22). These USMnO are further coated with zwitterionic dopamine sulfonate (ZDS) molecules, which improves their biocompatibility and prevents nonspecific binding of serum albumins. Interestingly, USMnO@ZDS are capable of passing through the blood-brain barrier (BBB), which enables the acquisition of clear images showing brain anatomic structures with T1-weighted contrast-enhanced MRI. Therefore, our USMnO@ZDS could be used as a promising MRI CA for the flexible and accurate diagnosis of brain diseases, which is also instructive for the construction of manganese-based CA with a high MRI performance.

Abstract
Objective: To evaluate the short-term efficacy and perioperative safety of catheter-based intervention in patients with pulmonary vein stenosis caused by fibrosing mediastinitis (FM). Methods: It was a case series study. Consecutive patients with pulmonary vein stenosis caused by FM, who underwent percutaneous pulmonary vein angioplasty in Gansu Provincial Hospital from January 2018 to June 2020, were retrospective enrolled. The baseline characteristics, comorbidities, exercise capacity and hemodynamic data before and after treatment were compared, and the procedural related complications were evaluated. Results: A total of 30 patients ((64.3±7.1) years, 15 males) were included. Sixty-three pulmonary vein stenosis were treated by 32 percutaneous pulmonary vein angioplasty procedures. Forty-four stents were implanted in 41 pulmonary veins after balloon angioplasty, and the diameter of implanted stents was (8.3±1.2)mm. Balloon angioplasty was performed on 22 pulmonary vein stenosis, the mean balloon diameter was (4.2±2.1)mm. The pulmonary vein diameter increased from (2.6±1.3) to (6.6±2.6) mm (P<0.001) and the pressure gradient across the pulmonary vein stenotic segment reduced from 19 (12, 29) to 2 (0, 4) mmHg (1 mmHg=0.133 kPa) (P<0.001) immediately post procedure. The pulmonary vein flow grade was significantly improved compared with baseline (P<0.001). The most common operation related complications were lung injury (44.0% (11/25)) and hemoptysis (18.8% (6/32)), which did not need special treatment. During the 2.0 (1.3, 3.2) months follow-up, the WHO functional class was significantly improved (P<0.05), the 6-minute walking distance increased from (254.8±114.5) m to (342.8±72.4)m (P<0.05), the mean pulmonary arterial pressure decreased from (40.9±8.3) mmHg to (35.4±7.7) mmHg (P<0.01), 17 out of 19 patients with refractory pleural effusion experienced total remission during the follow-up period (P<0.001). CT pulmonary venography was repeated in 17 patients. The incidence of in-stent restenosis of pulmonary vein was 24.0% (6/25). Conclusions: Percutaneous pulmonary vein angioplasty is effective for the treatment of pulmonary vein stenosis caused by fibrosing mediastinitis. However, it's not so safe, procedural related complication should be paid attention to and the rate of in-stent restenosis is relative high during the short-term follow-up.

Abstract
Arsenic trioxide (ATO, As2O3), an active ingredient of traditional Chinese medicine, has been approved by the U.S. Food and Drug Administration as an effective therapeutic agent for acute promyelocytic leukemia (APL). However, the application of ATO in treating advanced solid tumors like hepatocellular carcinoma (HCC) is still restricted by limited therapeutic efficacy and insufferable side effects. To solve this problem, we reported a general and facile strategy using human serum albumin (HSA) as a template for synthesizing a series of ATO-based nanoparticles with uniform single-albumin size. Then, we prepared a multifunctional drug delivery system (MDDS) based on MnAs/HSA termed MnAs/ICG/HSA-RGD, and tested its efficacy both in vitro and in vivo. Our results revealed that the photothermal effect of MnAs/ICG/HSA-RGD can not only cause irreversible damage to the tumor but also accelerate the discharge of As and Mn2+ ions, enabling responsive chemotherapy and magnetic resonance imaging. Interestingly, the expression of HSP90, vimentin, and MMP-9 in tumor cells was inhibited during the treatment, resulting in less metastasis and recurrence. Moreover, no apparent side effect has been observed during the treatment. Therefore, MnAs/ICG/HSA-RGD can be considered as a promising option for HCC with excellent therapeutic efficacy and minimum side effects.

Abstract
BACKGROUND Adjuvant abemaciclib combined with endocrine therapy (ET) previously demonstrated clinically meaningful improvement in invasive disease-free survival (IDFS) and distant relapse-free survival (DRFS) in hormone receptor-positive, human epidermal growth factor receptor 2-negative, node-positive, high-risk early breast cancer at the second interim analysis, however follow-up was limited. Here, we present results of the prespecified primary outcome analysis and an additional follow-up analysis. PATIENTS AND METHODS This global, phase III, open-label trial randomized (1 : 1) 5637 patients to adjuvant ET for ≥5 years ± abemaciclib for 2 years. Cohort 1 enrolled patients with ≥4 positive axillary lymph nodes (ALNs), or 1-3 positive ALNs and either grade 3 disease or tumor ≥5 cm. Cohort 2 enrolled patients with 1-3 positive ALNs and centrally determined high Ki-67 index (≥20%). The primary endpoint was IDFS in the intent-to-treat population (cohorts 1 and 2). Secondary endpoints were IDFS in patients with high Ki-67, DRFS, overall survival, and safety. RESULTS At the primary outcome analysis, with 19 months median follow-up time, abemaciclib + ET resulted in a 29% reduction in the risk of developing an IDFS event [hazard ratio (HR) = 0.71, 95% confidence interval (CI) 0.58-0.87; nominal P = 0.0009]. At the additional follow-up analysis, with 27 months median follow-up and 90% of patients off treatment, IDFS (HR = 0.70, 95% CI 0.59-0.82; nominal P < 0.0001) and DRFS (HR = 0.69, 95% CI 0.57-0.83; nominal P < 0.0001) benefit was maintained. The absolute improvements in 3-year IDFS and DRFS rates were 5.4% and 4.2%, respectively. Whereas Ki-67 index was prognostic, abemaciclib benefit was consistent regardless of Ki-67 index. Safety data were consistent with the known abemaciclib risk profile. CONCLUSION Abemaciclib + ET significantly improved IDFS in patients with hormone receptor-positive, human epidermal growth factor receptor 2-negative, node-positive, high-risk early breast cancer, with an acceptable safety profile. Ki-67 index was prognostic, but abemaciclib benefit was observed regardless of Ki-67 index. Overall, the robust treatment benefit of abemaciclib extended beyond the 2-year treatment period.

Abstract
Abstract
Aim
Treatment of skin and soft tissue abscesses forms a substantial part of the emergency general surgery workload. Abscesses account for approximately 2% of presentations to Accident and Emergency, with 0.9% of patients requiring surgical intervention. Incision and drainage is often performed in theatre and may necessitate admission to hospital, impacting bed space and theatre availability. This study aims to identify if the introduction of a clinic-based abscess service could reduce the number of abscess drainages in theatre without compromise to clinical outcomes.
Method
Retrospective data was collected for patients undergoing abscess treatment at Musgrove Park Hospital (Taunton) in September 2019. Subsequently, a Nurse-led abscess drainage pathway was initiated in Emergency Surgery Ambulatory Clinic (ESAC) encompassing initial assessment and drainage at the bedside. Prospective data was then collected for abscesses drained in theatre and ESAC during September 2020 and compared with data from 2019.
Result
22 abscess drainages were performed in September 2019 vs 25 in September 2020. 8 cases were carried out in theatre during September 2020, with the rest being treated in ESAC. Of those who were treated in clinic (n = 17), admission was prevented in 16 patients. Readmission rates were similar between ESAC (16%) and theatre (18.1%).
Conclusions
A clinic-based abscess service is achievable and prevents unnecessary use of theatres and hospital admissions, with comparable re-presentation rates. A nurse led approach also relieves pressure on Doctors during busy surgical on calls. Nonetheless, a larger data set would be needed to consolidate the findings from this study.

Abstract
BACKGROUND Thyroid-associated ophthalmopathy (TAO), one of the most common orbital diseases in adults, seriously reduces patients' quality of life. Although human tear proteomics identified many abnormal expressed proteins and proposed several pathogeneses of TAO, most of these studies focused on the active stage or mixed types in TAO. In this study we identified significantly changed proteins and preliminary revealed the potential signalling pathways and mechanisms of TAO with the late, inactive stage. PATIENTS AND METHODS Tears from TAO patients (n=6) with a CAS score < 3 and 6 control healthy subject were collected. The pooled tears were further fractionated using high pH reversed-phase chromatography, then submitted to LC-MS/MS and subsequent bioinformatic analysis. RESULTS Proteomic profiling identified 107 significantly changed proteins between the inactive stage of TAO patients and healthy cases. Among these proteins, 62 were upregulated, and 45 were downregulated in TAO cases compared to healthy individuals. Enrichment analysis revealed that the immune system, cell cycle, metabolism (carbohydrate metabolism and metabolism of cofactors and vitamins), protein synthesis and degradation might play a vital role in the progress of inactive TAO. The present investigation represents the first proteomic tear study of TAO patients in the inactive stage. CONCLUSION The results shed light on the differences between inactive TAO patients and healthy cases, thus enabling us to understand better the molecular mechanisms and potential targets for the treatment of inactive TAO.

Abstract
Objectives: Intracerebral hemorrhage (ICH) is a devastating type of strokes that carries high mortality rates, but effective therapeutic options are still lacking. Here, the adult rat model of ICH was used to investigate the efficacy of a combinational therapy of deferoxamine (DFX) and minocycline.Methods: The ICH was induced by stereotaxic infusion of collagenase into striatum of adult rats. After the induction of ICH, rats were treated with intraperitoneal injection of deferoxamine (50 mg/kg), minocycline (45 mg/kg), or both agents, at 2 hours after ICH and then every 12 hours for up to 3 days. The vehicle group were treated with phosphate-buffered saline (PBS) only. Rats were killed at 1, 2, and 3 day(s) for examination of iron deposition, neuronal death, neurological deficits, the area of brain damage, activation of microglia/macrophages.Results: Our data revealed that the systemic administration of DFX and/or minocycline decreased iron accumulation. And immunofluorescence staining results indicated that drug-treated group significantly decreased the neuronal degeneration, the number of activated microglia/macrophages and the amount of cell death after ICH. In addition, neurological deficits caused by ICH were improved in the presence of DFX and/or minocycline compare with vehicle group. Furthermore, the combination treatment showed better effects in neuroprotection and anti-inflammation when compared to the monotherapy groups.Conclusions: The combination therapy significantly reduces the number of neuronal deaths, suppresses of the activation of microglia/macrophages, decreases iron accumulation in the area around the hematoma, lessening the brain damage area, and improving neurological deficits in ICH.

Abstract
BACKGROUND Visceral function localization of the brain is very complex. For many years, people have been actively exploring the neural mechanism regulating visceral and substance metabolism, clarifying the complex relationship between the brain and peripheral nervous system related to the regulation of visceral activity, and analyzing its complex neural pathways. The brain is the advanced center of visceral function regulation. As an advanced center for substance metabolism and visceral regulation, the hippocampus is crucial for regulating visceral function. The liver is the core organ of material metabolism, and its afferent signals are mainly projected to the Nucleus of the solitary tract(NTS) through vagus nerve, and then they are projected to the hypothalamus and limbic system. MATERIALS AND METHODS We placed a stereotaxic instrument on the head of each rat and performed craniotomy to open a window above the left hippocampus. We used gold-plated tungsten electrodes to monitor hippocampal neuronal discharges. Grounding was achieved using screws and silver wire. We electrically stimulated the liver branch of the vagus nerve and observed changes in hippocampal neuron discharges using a biological method; in this way, we identified hepatosensitive hippocampal region. We injected FluoroGold into this region and related brain areas. After 3 days, the rats were sacrificed and perfused; the hippocampi were fixed, dehydated, frozen, sectioned, and subjected to fluorescence microscopy. RESULTS Nerve discharge frequency and amplitude significantly increased in the hippocampal CA3 region (AP: -4.9, ML: -5.1, DV: -5.0 mm). After FluoroGold was injected into the left hepatosensitive region in the hippocampus, labeled cells were found in the contralateral hippocampus, ipsilateral piriform cortex (PC), locus coeruleus (LC) and bilateral lateral hypothalamus (LHA); fluorescence in the ipsilateral hypothalamus was stronger than that of the contralateral hypothalamus. FluoroGold was injected into the LHA, PC, and LC; no labeled cells were found in the hippocampal CA3 region or in the control group. CONCLUSIONS The hippocampal CA3 area of rats may contain a hepatosensitive region that plays important roles in the regulation of liver and other organ function. These region may receive input from the LHA, PC, and LC.

Abstract
Abstract
Aim
Hypoglossal nerve injury is a rare complication in anaesthetic and surgical practice with only a few cases worldwide. This report describes the pathophysiology of this condition and highlights the key managements steps and expected outcomes for clinicians and patients.
Case
An open reduction and internal fixation of a left humeral fracture was performed on a healthy female patient in her mid-fifties under general anaesthesia. Two hours post-operatively, she developed left sided tongue swelling and deviation with dysphagia and dysarthria. Urgent CT head and MRA scans showed no abnormalities, leading to a diagnosis of isolated left hypoglossal nerve injury. Neurology and SALT were both involved in her care, but she ultimately made a full functional recovery after six months without any specific intervention.
Conclusions
A clear history, examination and high index of suspicion are crucial in the diagnosis of a hypoglossal nerve palsy. Cross sectional imaging is necessary to exclude any intracranial lesions, but intervention is rarely required, and patients should expect a slow but complete recovery over a period of months.

Abstract
Hollow iron oxide nanoparticles (NPs) are an attractive class of hollow nanostructures that have received significant attention in the biomedical field due to their low toxicity, good biocompatibility, and intrinsic magnetic nature. We review the recent advances in the preparation, surface functionalization, and biomedical applications of hollow iron oxide NPs. Hollow iron oxide NPs are generally synthesized by the following five strategies, including the Kirkendall effect, galvanic replacement, chemical etching, nano template-mediated, and hydrothermal/solvothermal routes. We also summarize the general strategies for iron oxide NP surface functionalization. Moreover, various promising biomedical applications of hollow iron oxide NPs, including magnetic resonance imaging, drug delivery, and cancer therapy, are highlighted in detail. Finally, perspectives of hollow iron oxide NPs are provided.

Abstract
Objective: To explore the correlation between alcohol drinking and high-risk sexual behaviors in HIV negative clients of female sex workers and provide scientific evidence for prevention of HIV sexual transmission. Methods: A cross-sectional survey was conducted in HIV negative clients in Ji'nan and Haikou from December 2018 to May 2019. The estimated sample size was 337, the information about their demographic characteristics, AIDS knowledge awareness, sexual behaviors and alcohol drinking habit were collected through convenience sampling. The data were analyzed by using SPSS 24.0 software. Results: A total of 381 clients were included in this study. Most of them were less than 40 years old, accounting for 89.2% (340/381); 85.3% of them (325/381) reported an education level of high school and above; the clients who were married, had cohabitation with females or had girl friends accounted for 53.2% (202/380). The overall awareness rate of AIDS knowledge was 83.7% (318/380). Of all participants, 80.8% (308/381) had commercial sex in the past year, 79.8% (304/381) had non-commercial sex partners, 62.7% (239/381) had high-risk sexual behaviors. The results of logistic regression showed that compared with those with alcohol drinking frequency ≤2 times per month in last year, the clients with alcohol drinking frequency more than once a week (aOR=3.22, 95%CI: 1.25-8.27) were more likely to have high risk sexual behaviors after adjustment for age, living area, location type of residence, time of local residence, education level, monthly income level, occupation, marital status, knowledge awareness of AIDS and HIV related services, the number of commercial or non-commercial sexual partners in the past year, cost of commercial sex and HIV test frequency. Conclusions: Alcohol drinking is related to high risk sexual behaviors in HIV negative clients, and will increase the risk of HIV transmission. To control AIDS, the intervention of alcohol drinking should be combined with other preventions to improve the correct use of condoms.

Abstract
BACKGROUND Ligation of intersphincteric tract (LIFT) is a sphincter-saving technique used to treat anal fistulas. Incorporation of a bioprosthesis in LIFT (BioLIFT) aims to improve healing. The use of cross-linked porcine dermal collagen mesh Permacol™ in BioLIFT has never been investigated. The aim of this study was to compare the healing rates and outcome of LIFT and BioLIFT for complex anal fistulas using the Permacol™ biological mesh. METHODS A retrospective analysis of all patients having LIFT or BioLIFT for complex fistulas from January 2010 to November 2019 was performed in a tertiary referral centre. Patient data from a prospectively collected database of all patients having LIFT or BioLIFT were analyzed. RESULTS LIFT and BioLIFT were performed in 48 (82.8%) and 10 (17.2%) patients, respectively. All BioLIFT patients had previous interventions for their fistulas compared to 30 (62.5%) of patients who had LIFT, p = 0.023. The primary healing rate for LIFT was 87.5% (42/48) compared to 80% (8/10) in BioLIFT, (p = 0.42). Eight (13.8%) patients developed complications, 6 (12.5%) in the LIFT group vs 2 (20%) in the BioLIFT group (p = 0.62). On univariate analysis, the number of previous operations was predictive of complications (p = 0.03). BioLIFT was not associated with complication (OR = 1.75, 95% CI: 0.30-10.3, p = 0.54) or primary healing (OR = 0.57, 95% CI: 0.97-3.36, p = 0.54). There was no significant difference in recurrence (LIFT 12.5% vs BioLIFT 0%, p = 0.58). Kaplan-Meier analysis found no difference in time to recurrence between the two groups (p = 0.65). CONCLUSION Permacol™ mesh in BioLIFT is feasible and achieves a high primary healing rate of 80%. Prospective evidence is needed to establish the benefits of BioLIFT and determine whether Permacol™ is superior to the non-cross-linked porcine submucosal mesh.

Abstract
Objective: To investigate the expression and significance of Nek2B and β-catenin expression in triple negative breast cancer (TNBC) at molecule levels. Methods: By using the methods of bioinformatics [GEO2R online tool, gene ontology (GO) function analysis, KEGG biological pathway enrichment analysis], the differentially expressed genes were screened from TNBC microarray data.Expression levels of Nek2B and β-catenin TNBC cell lines were detected by Western blot and qRT-PCR.From January 1, 2007 to December 31, 2012, eighty cases of TNBC were collected from the Second Hospital of Shanxi Medical University. The expression of Nek2B in TNBC tumor tissue was detected by immunohistochemistry and tissue microarray, and the relationship between Nek2B and clinical pathological characteristics of TNBC was analyzed. Results: Through bioinformatics analysis of the cDNA chip sets of 2 TNBC tumors(GSE38959,GSE27447), 998 differentially expressed genes were obtained in the initial screening, and 13 differentially expressed genes were revealed after intersection. The results of biological pathway analysis showed that the common differential expression genes were closely related to Wnt/β-catenin pathway, among which Nek2 expression showed the greatest difference and was associated with poor prognosis. Expression intensity of Nek2B and repeated β-catenin in the same TNBC cell line was consistent.The results of immunohistochemistry showed that the high expression of Nek2B was related to the high histological stage (G3;84.3% vs.37.9%, P<0.001), lymph node metastasis group (76.7% vs.54.1%, P=0.032), high Ki-67 positive index group (78.6% vs.52.6%, P=0.007) and β-catenin positive expression group (72.5% vs.27.3%, P=0.018). Conclusions: The high level of Nek2B expression is related to a poor prognosis in TNBC patients. In TNBC tissues and cells, the expression of Nek2B is correlated with β-catenin, suggesting that Nek2B may affect the occurrence and development of TNBC by regulating the Wnt/β-catenin patients signaling pathway.

Abstract
BACKGROUND This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. METHODS This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery. RESULTS A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498). CONCLUSION There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Abstract
Expanding the use of arsenic trioxide (ATO, As2O3) in cancer chemotherapy has received extensive attention in recent years owing to its remarkable efficacy in treating acute promyelocytic leukemia (APL). To date, the use of ATO for clinical treatment of solid tumors is still limited by its poor biocompatibility and severe toxic side effects. To address these limitations, here we developed a pH-low insertion peptide (pHLIP) modified ATO-based multifunctional drug-delivery system (DDS), which is termed MnAs@SiO2-pHLIP. With the coating of pHLIP, MnAs@SiO2-pHLIP could efficiently target the acidic tumor microenvironment, resulting in high intracellular accumulation of the DDS. As a "smart" nanoparticle (NP) platform, the DDS could controllably discharge the loaded ATO in response to acidic environments, which promotes the apoptosis of cancer cells. The features of controlled release capacity and the outstanding targeting ability contribute to better anticancer efficacy and less toxicity towards normal tissues compared with free ATO. It is worth noting that the acidic tumor microenvironment would also trigger the release of manganese ions (Mn2+) that brighten the T1 signal, which is exploited for real-time monitoring via contrast-enhanced magnetic resonance imaging (MRI). These multifunctional features, as demonstrated by both in vitro and in vivo experiments, could potentially expand the use of ATO to the treatment of solid tumors. We believe that MnAs@SiO2-pHLIP could serve as an auspicious agent for cancer theranostics and find tremendous applications in cancer management.

Abstract
We introduce and demonstrate a switchable novel linear polarization grating (LPG) consisting of a circular polarization grating (CPG) and a special cycloidal diffractive quarter waveplate (CQWP). The CQWP is developed that marvelously matches the polarization-state of beams passing through the CPG. Such an LPG is so polarization-sensitive that it can split an incident linear polarized beam into two proportionally controllable left- or right-handed circularly polarized lights. We establish rigorous simulation model based on finite element method to investigate near-field polarization-state distribution of CPGs. Furthermore, LPGs are demonstrated and the diffraction properties are obtained with simulation and Jones Matrix analysis. The combination of CPGs and CQWPs is achieved with polymerizable liquid crystal. The experimental results of deflection angle and polarization selectivity of LPGs are consistent with those of simulation.

Abstract
Objective: To evaluate the feasibility and safety percutaneous pulmonary vein intervention in patients with severe pulmonary vein stenosis (PVS) caused by fibrosing mediastinitis(FM). Methods: This retrospective analysis included 5 FM patients (2 male, 3 female, 54-77 years old) confirmed by clinical presentation and chest computed tomography (CT) scan from January to June 2018 who were from Gansu Provincial Hospital and Shanghai Chest Hospital. CT pulmonary angiography (CTPA) further revealed severe PVS caused by fibrotic tissue compression in mediastinum. After selective pulmonary vein angiography, gradually balloon angioplasty was used to expand the pulmonary vein and then stents were implanted in the pre-dilated stenotic pulmonary veins. Evaluation of therapeutic effect was made at 6 months after the procedure. Results: All of 11 serious compression PVS were treated with stent implantation (diameter: 7-10 mm, length: 17-27 mm). After stenting, degree of pulmonary vein stenosis decreased from (83±16)% to (12±4)% (P<0.01). The minimal diameter of the stenotic pulmonary vein was significantly increased from (0.8±0.5)mm to (7.5±0.8)mm (P<0.01). Trans-stenotic gradient decreased from (27.0±15.1)mmHg (1 mmHg=0.133 kPa) to (2.50±0.58)mmHg (P<0.05). Mean pulmonary pressure measured by cardiac catheter decreased from (45.0±9.0)mmHg to (38.7±8.4)mmHg (P<0.05). One patient experienced cardiac arrest due to vagal nerve reflex during big sizing balloon stent dilation and recovered after cardiopulmonary resuscitation. There were no other serious procedure related complications. During the follow-up, severe stenosis at end of proximal stent was evidenced in 1 patient due to fibrotic compression, and another patient developed in-stent thrombosis due to discontinuation of prescribed anticoagulant. Conclusion: Percutaneous intervention for severe pulmonary vein stenosis caused by FM is feasible and safe, and can improve hemodynamic caused by the compression of mediastinal vascular structures in these carefully selected patients.

Abstract
Objective: To examine the association of hyperglycemia and postoperative complications in non-diabetic patients underwent pancreaticoduodenectomy(PD). Methods: The clinical data of 209 non-diabetic patients who underwent PD from January 2012 to June 2018 at Department of Pancreatic and Biliary Surgery, the First Affiliated Hospital of Harbin Medical University and met the inclusion criteria were retrospectively analyzed. According to the diagnostic criteria of postoperative hyperglycemia, the patients were divided into postoperative hyperglycemia group (167 cases, 79.9%) and control group(42 cases, 20.1%). The propensity score matching(PSM) method was used to eliminate the difference between groups(caliper value=0.02; 38 cases in control group including 30 males and 8 females with age of 59.0 years;38 cases in postoperative hyperglycemia group including 32 males and 6 females with age of 61.0 years;37 cases of pancreatic head carcinoma,30 cases of periampullary carcinoma and 9 cases of benign diseases). A comparative analysis was applied for preoperative data, surgical related indicators and postoperative complication rates.The receiver operating characteristic(ROC) curve was used to calculate the area under the curve(AUC) of blood glucose values on postoperative day 1,3 and 5(POD1, POD3, POD5), to determine the high-risk blood glucose cutoff value of complications and to evaluate its sensitivity and specificity for the prediction of postoperative complications. Results: Univariate analysis showed that the differences in gender, body mass index, preoperative blood glucose, and serum urea nitrogen levels were statistically significant before PSM.There was no significant difference in the preoperative data between the two groups after PSM. Compared with the control group, the incidence of postoperative pancreatic fistula (31.6% vs. 5.3%), abdominal infection(29.0% vs. 7.9%) and Clavien-Dindo Ⅲ-Ⅴ complications(31.6% vs.7.9%) were statistically different(χ(2)=7.092,P=0.008; χ(2)=4.290,P=0.038; χ(2)=5.316,P=0.021), respectively. According to the AUC on POD3,the blood glucose value ≥8.860 mmol/L was an independent risk factor for pancreatic fistula with sensitivity of 58.3% and specificity of 76.9%,the blood glucose value ≥9.130 mmol/L was an independent risk factor for abdominal infection with sensitivity of 54.5% and specificity of 81.5% and the blood glucose value ≥7.685 mmol/L was independent risk factor of Clavien-Dindo Ⅲ-Ⅴ complications with sensitivity of 75.0% and specificity of 57.7%. Conclusions: Postoperative hyperglycemia in non-diabetic patients is associated with postoperative pancreatic fistula, abdominal infection, and Clavien-Dindo Ⅲ-Ⅴ complications.According to the early postoperative blood glucose value,the occurrence of postoperative pancreatic fistula, abdominal infection and Clavien-Dindo Ⅲ- Ⅴ complications can be effectively predicted.

Abstract
Multifunctional nanoplatforms featuring promising properties including excellent loading efficiency, real-time monitoring, and improved cargo bioavailability and bioselectivity are in great demand by the biomedical research community. During the development of such nanoplatforms, stimuli-responsive nanoparticles (NPs) as a smart nanoplatform have recently received extensive attention. Herein, we report small-sized octapod-shaped hollow porous manganese(II) oxide (HPMO) NPs as a stimuli-responsive T1-activatable nanoplatform for tumor-specific cargo delivery and real-time monitoring. The HPMO NPs functionalized by zwitterionic dopamine sulfonate (ZDS) can act as a versatile platform to load organic dyes or chemotherapeutic drugs with high loading efficiency. The obtained Cargo@HPMO would decompose into paramagnetic Mn2+ ions and subsequently release cargoes in mild acidic conditions, especially in tumor microenvironment and lysosome. The released Mn2+ can enhance T1 magnetic resonance signal for real-time monitoring of the cargo delivery in vivo. This octapod-shaped Cargo@HPMO can act as a smart and versatile nanoplatform with pH-responsive multimodal imaging and site-specific drug delivery for the development of accurate diagnosis and effective therapy for cancer.
