Abstract
Background Uterine torsion, the most complicated cause of maternal dystocia recorded in bovine, usually followed by incomplete cervical dilatation after successful detorsion, which interfere with vaginal fetal delivery. Aim This study aimed to evaluate the histopathological changes, variable collagen concentrations, and vascular endothelial growth factor expressions in uterine and cervical tissues following successful detorsion. Methods Animals were classified into four groups; normally calved cases (group A), cases that respond successfully to detorsion and followed by vaginal fetal delivery without (group B) or with (group C) cervical laceration, and cases that suffered from failure of complete cervical dilatation after successful detorsion (group D). Results Histopathological findings revealed variable changes in all uterine torsion affected groups, which were characteristic and marked in animals that suffered from failure of complete cervical dilatation following successful detorsion. Moreover, failure of cervical dilatation was associated with the highest collagen concentrations as shown by Masson trichrome stain. On the other hand, immunohistochemical findings showed that the normally calved cases have the highest vascular endothelial growth factor expression compared with animals that suffered from failure of complete cervical dilatation. Conclusion Our results showed that the vascular endothelial growth factor is essential for cervical dilatation and its lower expression is accompanied by incomplete cervical dilatation following successful detorsion.

Abstract
Introduction and Aim Increased angiogenesis in BM is one of the characteristics of chronic myeloid leukemia (CML) implicated in its progression. Vascular endothelial growth factor (VEGF) one of the most potent regulator of angiogenesis is increased in CML. The prognostic impact of serum VEGF in CML is largely unknown with sparse literature from India. So the present study aimed to measure serum VEGF levels in different phases of CML and to assess its prognostic significance using Hasford score. Methods Forty Ph + patients of CML were enrolled in the study. Complete clinical history and physical examination was done. Hemogram was done by Beckman Coulter LH 500. Peripheral smear (Wright's stain) was done by microscopy. Serum VEGF (plain vial) using ELISA was calculated. Statistical analysis was performed using SPSS software version 20. Results The mean serum VEGF levels were significantly higher in patients than in controls (p < 0.0001). The patients in accelerated/blast phase demonstrated significantly higher levels of serum VEGF (mean 151 pg/mL) than those in the chronic phase (mean 90.87 pg/mL) (p = 0.02). Serum VEGF levels showed a significant positive correlation with the overall Hasford prognostic score (p = 0.023). Conclusion Serum VEGF levels can serve as an independent prognostic marker in CML patients irrespective of phase of CML. Also, S. VEGF levels can be used to monitor patients on imatinib therapy and identify those who might benefit from antiangiogenesis therapy. However, larger studies are needed with a larger number of patients in different phases of CML to validate our findings and thus pave the way for future research.

Abstract
PURPOSE To investigate the value of a radiomics model based on dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and diffusion weighted imaging (DWI) in estimating isocitrate dehydrogenase 1 (IDH1) mutation and angiogenesis in gliomas. METHOD One hundred glioma patients with DCE-MRI and DWI were enrolled in this study (training and validation groups with a ratio of 7:3). The IDH1 genotypes and expression of vascular endothelial growth factor (VEGF) in gliomas were assessed by immunohistochemistry. Radiomics features were extracted by an open source software (3DSlicer) and reduced using Least absolute shrinkage and selection operator (Lasso). The support vector machine (SVM) model was developed based on the most useful predictive radiomics features. The conventional model was built by the selected clinical and morphological features. Finally, a combined model including radiomics signature, age and enhancement degree was established. Receiver operator characteristic (ROC) curve was implemented to assess the diagnostic performance of the three models. RESULTS For IDH1 mutation, the combined model achieved the highest area under curve (AUC) in comparison with the SVM and conventional models (training group, AUC = 0.967, 0.939 and 0.906; validation group, AUC = 0.909, 0.880 and 0.842). Furthermore, the SVM model showed good diagnostic performance in estimating gliomas VEGF expression (validation group, AUC = 0.919). CONCLUSIONS The radiomics model based on DCE-MRI and DWI can have a considerable effect on the evaluation of IDH1 mutation and angiogenesis in gliomas.

Abstract
Patients with type 1 diabetes mellitus (T1DM) are vulnerable to developing diabetic retinopathy even under insulin therapy. Thus, this study was designed to evaluate the efficacy of hesperidin and insulin in rats with T1DM compared with insulin alone in improving diabetic retinal changes. Eighty rats were divided into four equal groups: group I, control rats without diabetes; group II, untreated rats with diabetes; group III, rats with diabetes treated daily with subcutaneous (SC) doses of long-acting insulin; and group IV, a rat with diabetes in which hesperidin was orally administered with SC insulin. The animals were assessed histologically, morphometrically, and biochemically. In group II, the thickness of all retinal layers decreased histologically. Ultrastructurally, degenerated retinal neurons and congested blood vessels were observed. Immunostaining detected elevated gene expression of advanced glycation end products. Gene expression of vascular endothelial growth factor, and glial fibrillary acidic protein were elevated. In this study, hesperidin supplementation with insulin significantly improved the retinal histological changes, supported by morphometric findings, compared with insulin alone. Moreover, treatment with hesperidin significantly reduced malondialdehyde and elevated serum antioxidant markers, including superoxide dismutase and catalase; furthermore, glutathione peroxidase decreased. Hesperidin might be an effective supplement for improving diabetic retinal complications occurring even with insulin treatment.

Abstract
BACKGROUND In recent years, numerous investigations have been conducted to determine the clinical significance and critical functions of vascular endothelial growth factor (VEGF) in various malignant cancers. The purpose of this meta-analysis was to comprehensively evaluate the prognostic and clinicopathological value of VEGF in patients with osteosarcoma. METHODS We performed a systematic literature retrieval of available databases. Odds ratios (ORs) or standard mean difference (SMD) for clinicopathological parameters, hazard ratios (HRs) for overall survival and disease-free survival were calculated to assess the correlation between VEGF expression and prognosis in patients with osteosarcoma. RESULTS A total of 22 studies with 1144 patients were included in our study. Pooled analyses showed that VEGF overexpression predicted worse overall survival (HR, 2.42; 95% CI, 1.87-3.11, p < 0.001) and disease-free survival (HR, 2.604; 95% CI, 1.698-3.995, p < 0.001), respectively. Furthermore, investigation regarding osteosarcoma clinicopathologic characteristics suggested that high VEGF expression was significantly associated with metastasis (OR, 4.39; 95% CI, 2.77-6.95; p < 0.001), clinical stage (OR, 0.73; 95% CI, 0.62-0.87; p < 0.001), and microvessel density (SMD, 3.33, 95% CI,1.57-5.10, p < 0.001), but not associated with tumor location, gender, age, local recurrence, and chemotherapy response. CONCLUSION Our meta-analysis findings suggest that elevated VEGF expression may be a predictive biomarker for poor prognosis and adverse clinicopathological characteristics in patients with osteosarcoma.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is a malignant tumor with rich blood supply. The blood supply is closely related to its occurrence and development. Contrast-enhanced ultrasound (CEUS) can quantitatively analyze the microcirculation blood flow of HCC, indirectly reflect its pathological characteristics, evaluate the curative effect, and guide clinical treatment.
AIM To investigate the characteristics of CEUS parameters of HCC residual lesions after transcatheter artery chemoembolization (TACE), and analyze their correlation with serum hypoxia inducible factor-1a (HIF-1a).
METHODS Eighty-six HCC patients treated with TACE were selected as the subjects. They were divided into either a no residual lesion group (52 cases) or a residual lesion group (34 cases). All patients underwent CEUS within 3 d before treatment and 30 d after treatment. The following perfusion parameters were measured: Maximum intensity (IMAX), time to peak (TTP), rise time (RT), and washout time (WT). The levels of serum HIF-1a and vascular endothelial growth factor (VEGF) were measured by enzyme-linked immunosorbent assay. The changes of perfusion parameters, and serum HIF-1a and VEGF levels before and after treatment were compared between the two groups.
RESULTS Before treatment, there was no significant difference in IMAX, RT, TTP, WT, or serum HIF-1a and VEGF between the two groups (P > 0.05). After treatment, the levels of serum HIF-1a and VEGF in the no residual lesion group were significantly lower than those before treatment (P < 0.05), and CEUS showed that there was no obvious perfusion in the lesions. In the residual lesion group, after treatment, the levels of serum HIF-1a and VEGF were significantly higher (P < 0.05), IMAX was significantly lower (P < 0.05), and RT, TTP, and WT were significantly longer than those before treatment (P < 0.05). After treatment, IMAX in the residual lesion group was positively correlated with the levels of HIF-1a (R2 = 0.74, P < 0.05), and TTP, RT, and WT were negatively correlated with the levels of HIF-1a (R2 = 0.56, 0.42, and 0.48, respectively; P < 0.05).
CONCLUSION CEUS can directly reflect the changes of HCC perfusion after TACE treatment, and the perfusion parameters (IMAX, TTP, RT, and WT) of residual tissues have a good correlation with the levels of serum HIF-1a, which can provide a reference for the comprehensive evaluation of the curative effect of TACE.

Abstract
Gastric cancer (GC) remains a serious oncological problem, ranking third in the structure of mortality from malignant neoplasms. Improving treatment outcomes for this pathology largely depends on understanding the pathogenesis and biological characteristics of GC, including the identification and characterization of diagnostic, prognostic, predictive, and therapeutic biomarkers. It is known that the main cause of death from malignant neoplasms and GC, in particular, is tumor metastasis. Given that angiogenesis is a critical process for tumor growth and metastasis, it is now considered an important marker of disease prognosis and sensitivity to anticancer therapy. In the presented review, modern concepts of the mechanisms of tumor vessel formation and the peculiarities of their morphology are considered; data on numerous factors influencing the formation of tumor microvessels and their role in GC progression are summarized; and various approaches to the classification of tumor vessels, as well as the methods for assessing angiogenesis activity in a tumor, are highlighted. Here, results from studies on the prognostic and predictive significance of tumor microvessels in GC are also discussed, and a new classification of tumor microvessels in GC, based on their morphology and clinical significance, is proposed for consideration.

Abstract
BACKGROUND Diabetic retinopathy (DR) is a serious and potentially blinding complication of diabetes mellitus. Retinal neovascularization is one of the main pathological features of proliferative DR, and inhibiting retinal neovascularization is a research focus.
AIM The aim was to evaluate the effect of intravitreal injection of recombinant human maspin on neovascularization in DR.
METHODS An oxygen-induced retinopathy (OIR) mouse model was used to simulate neovascularization in DR. New born C57BL/6J mice were randomly divided to a normal control group, a maspin injection OIR group, and an OIR group. The mice in the maspin injection OIR group were injected with recombinant human maspin in the bilateral vitreous cavity on postnatal day P12, and those in the OIR group were injected with sterile phosphate buffered saline. The protein expression of vascular endothelial growth factor (VEGF) and hypoxia-inducible factor 1-alpha (HIF-1α) in the retina was measured by western blotting, and the mRNA expression of VEGF and HIF-1α was measured by real-time polymerase chain reaction. The vascular cell nuclei that broke through the inner limiting membrane (ILM) were counted in haematoxylin-eosin stained retinal sections.
RESULTS It was found that the number of vascular cell nuclei breaking through the ILM was 31.8 ± 8.75 in the OIR group, which was significantly more than that in the normal control group (P < 0.001). The number of vascular cell nuclei breaking through the ILM was 6.19 ± 2.91 in the maspin injection OIR group, which was significantly less than that in OIR group (P < 0.01). The relative protein and mRNA expression of VEGF and HIF-1α was significantly lower in the retinas in the maspin injection OIR group than in those in the OIR group (P < 0.01).
CONCLUSION Maspin inhibited neovascularization in DR by modulating the HIF-1α/VEGF pathway, which provides a potential and effective strategy for the treatment of DR.

Abstract
Background Progression of diabetic retinopathy post cataract surgery is related to the increased level of vascular endothelial growth factor (VEGF) in ocular fluid post operatively. The aim of this study was to compare the VEGF level in tears post phacoemulsification between non-proliferative diabetic retinopathy (NPDR) and non-diabetic patients. Methods This was a prospective cohort study and was conducted from June 2017 to May 2019. Patients with underlying NPDR who were planned for phacoemulsification were recruited in this study. Non-diabetic patients who were planned for phacoemulsification were included as control group. Tears samples were collected using Schirmer strip two weeks prior to operation, at day (D) 7 and D30 post phacoemulsification. Tears samples were analyzed for VEGF level. Results A total of 65 patients were recruited in this study (NPDR: 32 and control: 33). There was significant increase of VEGF levels in tears from pre operation to D7 post phacoemulsification in NPDR (p < 0.001) and control (p < 0.001). There was also significant reduction of tear VEGF level from D7 to D30 post phacoemulsification in both groups (p < 0.001 in NPDR and p = 0.027 in control). The tear VEGF level was significantly higher in NPDR group compared to control at D7 post phacoemulsification (149.4 SD 55.2 pg/mL vs 109.7 SD 48.7 pg/mL, p = 0.003). Conclusion VEGF level in tears showed significant elevation post early cataract surgery in NPDR compared to non-diabetic patient. Therefore, tears VEGF level may provide as a non-invasive method to predict progression of diabetic retinopathy post operation among diabetic patients.

Abstract
OBJECTIVE Prolyl hydroxylase domain containing proteins (PHD) rigorously regulate intracellular hypoxia inducible factor-1 (HIF-1) protein expression and activity. Diabetes impairs PHD activity and attenuates abdominal aortic aneurysm (AAA) progression. The extent to which dysregulated PHD activity contributes to diabetes mediated AAA suppression remains undetermined. METHODS AAAs were induced in diabetic and non-diabetic male C57BL/6J mice via intra-aortic elastase infusion. A PHD inhibitor (JNJ-42041935, aka "JNJ", 150 mmol/kg) or vehicle alone was administered daily starting one day prior to AAA induction for 14 days. Influences on AAA progression was assessed via ultrasonography and histopathology. Expression of aortic HIF-1α, three of its target genes and macrophage derived mediators were assayed via quantitative reverse transcription polymerase chain reaction. Aneurysmal sections from AAA patients with and without diabetes (two patients in each group) were immunostained for HIF-1α and vascular endothelial growth factor (VEGF)-A. RESULTS Expression of HIF-1α target genes (erythropoietin, VEGF-A, and glucose transporter-1) was reduced by 45% - 95% in experimental diabetic aortas. Diameter enlargement was similarly limited, as were mural elastin degradation, leukocyte infiltration, and neo-angiogenesis (reduced capillary density and length) on histopathology. Pre-treatment with JNJ prior to AAA initiation augmented aortic HIF-1α target gene expression and aneurysm progression in diabetic mice, along with macrophage VEGF-A and matrix metalloproteinase 2 mRNA expression. No differences were noted in HIF-1α or VEGF-A expression on aortic immunohistochemical staining of human aortic tissue as a function of diabetes status. CONCLUSION Small molecule PHD inhibitor treatment reduces or offsets impairment of experimental AAA progression in hyperglycemic mice, highlighting the potential contribution of dysregulated PHD activity to diabetes mediated aneurysm suppression.

Abstract
In light of the intriguing potential of anti-angiogenic approach in suppressing choroidal neovascularization, we attempted to elaborate synthetic gene delivery systems encapsulating anti-angiogenic plasmid DNA as alternatives of clinical antibody-based therapeutics. Herein, block copolymer of cyclic Arg-Gly-Asp-poly(ethylene glycol)-poly(lysine-thiol) [RGD-PEG-PLys(thiol)] with multifunctional components was tailored in manufacture of core-shell DNA delivery nanoparticulates. Note that the polycationic PLys segments were electrostatically complexed with anionic plasmid DNA into nanoscaled core, and the tethered biocompatible PEG segments presented as the spatial shell (minimizing non-specific reactions in biological milieu). Furthermore, the aforementioned self-assembly was introduced with redox-responsive disulfide crosslinking due to the thiol coupling. Hence, reversible stabilities, namely stable in extracellular milieu but susceptible to disassemble for liberation of the DNA payloads in intracellular reducing microenvironment, were verified to facilitate transcellular gene transportation. In addition, RGD was installed onto the surface of the proposed self-assemblies with aim of targeted accumulation and internalization into angiogenic endothelial cells given that RGD receptors were specifically overexpressed on their cytomembrane surface. The proposed anti-angiogenic DNA therapeutics were validated to exert efficient expression of anti-angiogenic proteins in endothelial cells and elicit potent inhibition of ocular neovasculature post intravitreous administration. Hence, the present study approved the potential of gene therapy in treatment of choroidal neovascularization. In light of sustainable gene expression properties of DNA therapeutics, our proposed synthetic gene delivery system inspired prosperous potentials in long-term treatment of choroidal neovascularization, which should be emphasized to develop further towards clinical translations.

Abstract
BACKGROUND Preeclampsia is a pregnancy disorder characterized with abnormal placental angiogenesis. Vitamin D and long chain polyunsaturated fatty acids (LCPUFA) play a crucial role in pregnancy and are required for normal placental and fetal growth and development. This study reports the effect of maternal vitamin D on LCPUFA levels in the mother and offspring brain fatty acid levels and angiogenic markers in a rat model of preeclampsia. METHODS Female rats were divided into four groups from pre-pregnancy to pregnancy, viz Control; Preeclampsia (PE); Vitamin D deficient with PE (VDD-PE) and Vitamin D supplemented with PE (VDS-PE). Preeclampsia was induced by administering l-nitroarginine methyl ester (L-NAME) at the dose of 50 mg/kg body weight/day from day 14 to day 19 of gestation. Dams were sacrificed at d20 of gestation to collect dam blood, placenta and pup brain. LCPUFA levels from dam plasma, erythrocytes and placenta and its transcription factor peroxisome proliferator activated receptor gamma (PPAR-g) from placenta were estimated. Pup brain LCPUFA levels, angiogenic factors vascular endothelial growth factor (VEGF) and placental growth factor (PlGF) and transcription factor hypoxia inducible factor (Hif-1α) and PPAR-g were also estimated. RESULTS Maternal vitamin D status influences fatty acid levels. Placental PPAR-g levels were lower in the VDD-PE group as compared to the VDS-PE groups (p < 0.01). In the offspring brain, both PE and VDD-PE group showed lower levels of DHA (p < 0.05 for both) while saturated fatty acids (SFA) levels in the VDD-PE group were higher as compared to the control group (p < 0.05). VDD-PE group also showed lower levels of PlGF and PPAR-g (p < 0.01 and p < 0.05, respectively) in the pup brain while vitamin D supplementation demonstrated levels similar to control. CONCLUSION This study for the first time demonstrates that maternal vitamin D status influences LCPUFA metabolism and angiogenesis in the offspring brain.

Abstract
Label-free and turn-on DNA-binding protein detection based on the doxorubicin (Dox)-intercalated DNA as a signal stimulator in cathodic photoelectrochemistry is reported. The double-stranded DNA (dsDNA) acted as the matrix accommodating the intercalative Dox and allowed its effective photoelectrochemical (PEC) communication with the PbS quantum dots (QDs) for realizing cathodic photocurrent readout. In the presence of the target of the vascular endothelial growth factor (VEGF), the dsDNA was prevented from being digested by the exonuclease III (Exo III), allowing the anchor of Dox to perform as activation stimuli of the photocurrent. The VEGF can be detected in the linear range from 1.5 pM to 100 nM, with an impressively low detection limit of 0.49 pM. This study hints the prospect of DNA intercalated architectures as innovative signaling transduction elements for wide and versatile cathodic PEC bioassays. Effective signaling molecules that are conducive to probe-related cathodic PEC bioassays using DNA as the recognition or signification elements are scarce but very demanding. Herein, the doxorubicin intercalated in duplex DNA functions as an efficient signal stimulator of PbS-consisted photocathode, and thus hints the versatility of the strategy for various targets through cathodic photoelectrochemistry.

Abstract
Atrial fibrillation (AF) is a common form of arrhythmia with serious public health impacts, but its underlying mechanisms are not yet fully understood. Vascular endothelial growth factor (VEGF) is highly expressed in the atrium of patients with AF, but whether VEGF affects AF pathogenesis remains unclear. Pulmonary veins (PVs) are important sources for the genesis of atrial tachycardia or AF. Therefore, this study assessed the effects of VEGF on PV electrophysiological properties and evaluated its underlying mechanisms. Conventional microelectrodes and whole-cell patch clamps were performed using isolated rabbit PV preparations or single isolated PV cardiomyocytes before and after VEGF or VEGF receptor (VEGFR), Akt, NOS inhibitor administration. We found that VEGF (0.1, 1, and 10 ng/mL) reduced the PV beating rate in a dose-dependent manner. Furthermore, VEGF (10 ng/mL) reduced late diastolic depolarization and diastolic tension. Isoproterenol increased PV beating and burst firing, which was attenuated by VEGF (1 ng/mL). In the presence of VEGFR-1 inhibition (ZM306416 at 10 μM) and L-NAME (100 μM), VEGF (1 ng/mL) did not alter PV spontaneous activity. In isolated PV cardiomyocytes, VEGF (1 ng/mL) decreased L-type calcium, sodium/calcium exchanger, and late sodium currents. In conclusion, we found that VEGF reduces PV arrhythmogenesis by modulating sodium/calcium homeostasis through VEGFR-1/NOS signaling pathway.

Abstract
OBJECTIVE Diabetic macular edema (DME) is one of the most frequent causes of severe vision loss. The pathogenesis of DME is still not fully understood; however, it is hypothesized to result from breakdown of the blood-retinal barrier (BRB) due to retinal inflammation by vascular endothelial growth factor (VEGF) secretion under hyperglycemic conditions. In this investigation, we discovered that Prolyl-4-hydroxylase 2 (PHD2), an upstream regulator of hypoxia-inducible factor 1 (HIF-1) modulates VEGF expression and thus preserves BRB function in the mouse retina. MATERIALS AND METHODS Primary human retinal microvascular endothelial cells (hRMECs) were cultured in human endothelial serum-free growth medium and exposed to hyperglycemia. Changes in cell viability were investigated by an MTT assay. BRB function in each group was revealed by a paracellular permeability assay and trans-endothelial electrical resistance (TEER). Morphological changes in the BRB were investigated by immunofluorescence staining of occludin and zonula occludens-1 (ZO-1). The mRNA and protein levels of the tight junction proteins, PHD2, HIF-1α, and VEGF were measured by reverse transcription-quantitative PCR (RT-qPCR), western blot analysis and ELISA. RESULTS Under hyperglycemic conditions, the viability of hRMECs was decreased, and PHD2 expression was downregulated, accompanied by increased paracellular permeability and decreased trans-endothelial electrical resistance. Additionally, HIF-1α and VEGF expression levels were increased, whereas the expression levels of tight junction proteins, including occludin and ZO-1, were decreased and BRB function was compromised. The PHD2 activator R59949 (diacylglycerol kinase inhibitor II), altered these pathological changes, and the PHD2 inhibitor dimethyloxalylglycine (DMOG) resulted in the opposite effects. CONCLUSION These results demonstrated that PHD2 inhibited HIF-1 activity by inhibiting HIF-1α expression in hRMECs under hyperglycemic conditions, which led to the downregulation of the expression of the angiogenic factor VEGF, and thus helped to maintain the functions of hRMECs. Therefore, it is reasonable to propose that PHD2 could be a potential novel target for the treatment of DME or other diseases with a similar pathogenesis.

Abstract
BACKGROUND Pneumatosis intestinalis is a rare disease characterized by gas-filled cysts within the submucosa or serosa of the intestinal tract. In recent years, pneumatosis intestinalis was reported in patients undergoing cancer treatment, and some case reports exist that report that pneumatosis intestinalis occurs during administration of vascular endothelial growth factor inhibitors, such as bevacizumab and sunitinib. Here, we report the first case of pneumatosis intestinalis during lenvatinib treatment. CASE PRESENTATION A 77-year-old Japanese man presented to our hospital with a chief complaint of numbness in the right leg and weakness of the lower limbs 9 years after right thyroid lobectomy. Computed tomography showed a tumor 90 mm in size from the lumbar spine to the sacrum, causing spinal cord compression. Blood tests showed that the patient's thyroglobulin level was increased to 11,600 ng/ml. We diagnosed him with thyroid cancer with bone metastases. External beam radiotherapy (39 Gy/13 Fr) was performed on the bone metastases, followed by total thyroidectomy and radioactive iodine therapy. Four months after radioactive iodine therapy, lenvatinib was introduced because the symptoms of numbness and weakness recurred. Lenvatinib was introduced at dose of 24 mg, and then it was reduced to 14 mg owing to Common Terminology Criteria for Adverse Event grade 3 paronychia of the right foot. Although no further significant adverse events occurred, a scheduled computed tomography image showed pneumatosis intestinalis of the ascending colon 14 weeks after the introduction of lenvatinib. No abdominal or digestive symptoms were observed; therefore, we selected conservative treatment. We discontinued lenvatinib for a week, but we were required to restart lenvatinib as the numbness in the right leg worsened after withdrawal. Since the introduction of lenvatinib, 3 years and 5 months passed; we continued lenvatinib treatment, and the therapeutic effect remains partial response. There has been no recurrence of pneumatosis intestinalis. CONCLUSIONS Although rare, it is important to recognize that pneumatosis intestinalis can occur in association with lenvatinib and should be differentiated from intestinal perforation. Pneumatosis intestinalis association with lenvatinib can be improved by withdrawal.

Abstract
Dietary supplementation with 0.4 or 0.8% L-arginine (Arg) to gilts between days 14 and 25 of gestation enhances embryonic survival and vascular development in placentae; however, the underlying mechanisms are largely unknown. This study tested the hypothesis that Arg supplementation stimulated placental expression of mRNAs and proteins that enhance angiogenesis, including endothelial nitric oxide synthase (eNOS), vascular endothelial growth factor (VEGF), placental growth factor (PGF), GTP cyclohydrolase-I (GTP-CH1), ornithine decarboxylase (ODC1), and vascular endothelial growth factor receptors 1 and 2 (VEGFR1 and VEGFR2). Beginning on the day of breeding, gilts were fed daily 2 kg of a corn-soybean meal-based diet supplemented with 0.0 (control), 0.4, or 0.8% Arg. On day 25 of gestation, gilts were hysterectomized to obtain uteri and conceptuses for histochemical and biochemical analyses. eNOS and VEGFR1 proteins were localized to endothelial cells of maternal uterine blood vessels and to the uterine luminal epithelium, respectively. Compared with the control, dietary supplementation with 0.4 or 0.8% Arg increased (P < 0.05) the amounts of nitrite plus nitrate (NOx; oxidation products of NO) and polyamines in allantoic and amniotic fluids, concentrations of NOx, tetrahydrobiopterin (BH4, an essential cofactor for all NOS isoforms) and polyamines in placentae, as well as placental protein abundances of GTP-CH1 (the key enzyme for BH4 production) and ODC1 (the key enzyme for polyamine synthesis). Placental mRNA levels for GTP-CH1, eNOS, PGF, VEGF, and VEGFR2 increased in response to both 0.4% and 0.8% Arg supplementation. Collectively, these results indicate that dietary Arg supplementation to gilts between days 14 and 25 of pregnancy promotes placental angiogenesis by increasing the expression of mRNAs and proteins for angiogenic factors as well as NO and polyamine syntheses.

Abstract
Vascular perturbations and cerebral hypometabolism are emerging as important components of Alzheimer's disease (AD). While various in vivo imaging modalities have been designed to detect changes of cerebral perfusion and metabolism in AD patients and animal models, study results were often heterogenous with respect to imaging techniques and animal models. We therefore evaluated cerebral perfusion and glucose metabolism of two popular transgenic AD mouse strains, TgCRND8 and 5xFAD, at 7 and 12 months-of-age under identical conditions and analyzed possible molecular mechanisms underlying heterogeneous cerebrovascular phenotypes. Results revealed disparate findings in these two strains, displaying important aspects of AD progression. TgCRND8 mice showed significantly decreased cerebral blood flow and glucose metabolism with unchanged cerebral blood volume (CBV) at 12 months-of-age whereas 5xFAD mice showed unaltered glucose metabolism with significant increase in CBV at 12 months-of-age and a biphasic pattern of early hypoperfusion followed by a rebound to normal cerebral blood flow in late disease. Finally, immunoblotting assays suggested that VEGF dependent vascular tone change may restore normoperfusion and increase CBV in 5xFAD.

METHODS Peripheral blood eosinophils or EoL-1 eosinophilic leukemia cells were cocultured with nasal polyp fibroblasts (NPFs). Coculture-induced release of exosomes, major components of extracellular vesicles (EVs), and a profibrotic cytokine, vascular endothelial growth factor (VEGF), were evaluated by enzyme-linked immunosorbent assay. RESULTS Eosinophil-NPF interactions stimulated the release of exosomes and VEGF into culture supernatants. Coculture-induced release of exosomes was stimulated earlier than VEGF release, at 3 h of incubation. The average size of the EVs released by NPFs was 133 ± 3.6 nm. NPF-derived EVs (exosome concentration: 25 pg/mL) significantly stimulated VEGF release from EoL-1 cells. Pretreatment of NPFs with exosome inhibitor, GW4869 or DMA attenuated the release of exosomes and VEGF from cocultured EoL-1 cells and NPFs. CONCLUSION The results of this study indicate that eosinophil-fibroblast interactions are important in the pathophysiology of tissue remodeling in eosinophil-predominant airway inflammation and that NPF-derived exosomes play a crucial role in the release of VEGF.

Abstract
AIM The aim of this study was to identify differentially expressed microRNAs (miRNAs) in the vitreous of patients with proliferative diabetic retinopathy (PDR) and correlate some of them with growth factors. METHODS Vitreous samples were collected from 5 PDR eyes and 5 control eyes, and then miRNAs were assayed with next-generation sequencing (NGS). Three differentially expressed miRNAs were validated in vitreous of another cohort using reverse transcriptase quantitative polymerase chain reaction (RT-qPCR). RESULTS Transforming growth factor β (TGF-β) and vascular endothelial growth factor (VEGF) signaling pathway were excavated out through bioinformatic analysis of deregulated miRNAs. The expression of hsa-miR-24-3p, hsa-miR-197-3p and hsa-miR-3184-3p, VEGF-A and TGF-β were confirmed to be significantly higher in the vitreous of PDR eyes than controls(P < 0.05). Furthermore, Pearson's correlation analysis showed significantly positive correlations between these elevated miRNAs and growth factors (P < 0.05). CONCLUSIONS Elevated vitreous levels of hsa-miR-24-3p, hsa-miR-197-3p, hsa-miR-3184-3p in PDR patients may play roles in pathophysiology of PDR, the target mRNAs of which significantly enriched in VEGF and TGF-β signaling pathways. Positive correlations between elevated vitreous levels of the three miRNAs and VEGF-A, TGF-β in PDR patients could provide a novel research direction for PDR.

Abstract
OBJECTIVE To determine if genetic polymorphism of VEGF is associated with the development of endometriosis in Nigerian women. STUDY DESIGN Case control study of 100 women (50 healthy controls and 50 with endometriosis). Serum VEGF concentration of participants were determined using enzyme-linked immunosorbent assay (ELISA) technique. Genomic DNAs were isolated from peripheral blood samples and quantified by nanodrop spectrophotometer one. Single nucleotide polymorphisms genotyping was carried out by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP). RESULTS Mean age of participants was 32.96 ± 6.91 years for control and 32.04 ± 7.56 years for cases. VEGF levels in case and control groups were not statistically different (82.68 pg/ml [69.11-121.11 pg/ml] vs. 82.81 pg/ml [72.90-113.82 pg/ml] respectively; p = 0.967). All four genotypes examined were in Hardy-Weinberg equilibrium. Minor allele frequency of - 460T > C, - 1154G > A, + 936C > T and + 2578C > A were 24%, 8%, 6% and 10% in the control and 19%, 9%, 5% and 14% in endometriosis patients. However, allele and genotype distributions of - 460T > C, - 1154G > A, + 936C > T and + 2578C > A VEGF polymorphisms in endometriosis patients and control were not significantly different (p > 0.05). CONCLUSION Our preliminary findings revealed no association between endometriosis and - 460T > C, - 1154G > A, + 936C > T and + 2578C > A of VEGF genes among Nigerian women.

Abstract
Background Cigarette smoking is the most significant cause of oral cancer progression. Cigarette smoke condensate (CSC) has been shown to induce endoplasmic reticulum (ER) stress. Binding immunoglobulin protein (BiP) being as an ER stress regulator, has been reported to be implicated in malignant behaviors. Therefore, the aim of this study was to investigate the role of the ER stress-responsive protein, BiP, in CSC-induced oral squamous cell carcinoma (OSCC) malignancy. Methods The biological role of BiP in CSC-induced tumor progression was investigated in OSCC cells (YD38 and SCC25) and in a tumor xenograft mouse model. The expressions of related genes were investigated using quantitative RT-PCR and Western blot analysis. Cell migration and invasion were assessed using scratch wound healing and Transwell invasion assays. The effects of conditioned media from OSCC cells on the angiogenic activities of endothelial cells were analyzed using a tube formation assay. The interaction between miR-30a and BiP mRNA was detected using a luciferase reporter assay. Results Our results demonstrated that CSC increased the expression of BiP in time- and dose-dependent manners in YD38 and SCC25 cells, and that silencing BiP abrogated CSC-induced cell invasion and tumor-associated angiogenesis. Notably, the putative miR-30a binding site was observed in the 3′untranslated region (UTR) of BiP mRNA, and miR-30a suppressed BiP expression by targeting 3′UTR of BiP transcript. In addition, CSC increased the expression of BiP in OSCC cells by downregulating miR-30a. We also showed that BiP promoted invasion and tumor-associated angiogenesis by increasing the production and secretion of vascular endothelial growth factor in CSC-exposed OSCC cells. Moreover, BiP inhibition suppressed OSCC growth and reduced tumor vessel density in tumor-bearing mice administered with CSC. Conclusions These observations suggest that epigenetic regulation of BiP via miR-30a downregulation is involved in CSC-induced OSCC progression.

Abstract
OBJECTIVE To investigate the effect of refined moxibustion on expression of gastric mucosal epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF), and changes of metabolite profiles in gastric ulcer (GU) rats, so as to analyze its mechanism underlying improvement of GU. METHODS Male SD rats were randomized into control, model, acupoint moxibustion groups (n=6 per group). The GU model was induced by cold-restraint stress. The ignited refined moxa was applied to bilateral "Liangmen" (ST21) and "Zusanli" (ST36) for 3 cones/acupoint, once daily for 7 days. Then, we employed 1H NMR-based metabolomics approach to analyze the metabolic profiles of serum and stomach tissue samples. The conventional histopathological changes of the gastric mucosa were observed by H.E. stain and the expressions of EGFR and VEGF in the gastric mucosa were detected by immunohistochemistry. RESULTS Compared to the control group, the expression levels of EGFR and VEGF were significantly increased in the model group (P<0.01, P<0.05), and further notably up-regulated in the acupoint moxibustion group (P<0.001, P<0.01). Results of H.E. staining showed damage of the folds of gastric mucosa, disordered arrangement of the glands, infiltration of inflammatory cells and unclear structure of gastric mucosa in the model group, which was relatively milder in the acupoint moxibustion group. 1H-NMR technical analysis showed that in comparison with the control group, 11 and 11 metabolites in the stomach extract and plasma were increased, 10 in the gastric tissue and 3 in the plasma were decreased in the GU model group; while in comparison with the model group, 17 differently expressed metabolites in the gastric extract and 10 metabolites in the plasma restored to their levels of control group after the acupoint moxibustion intervention. These metabolites participate in 12 metabolic pathways including glycine, serine and threonine metabolism, glutathione metabolism, glycine metabolism, alanine, aspartic acid and glutamic acid metabolism, purine metabolism, glyoxylic acid and digarboxylic acid metabolism, biosynthesis of aminoacyl-tRNA, amino sugar and nucleotide sugar metabolism, cysteine and methionine metabolism, citrate cycle, pyruvate metabolism, and the mutual conversion of pentose and glucuronate,suggesting their involvement in moxibustion-induced improvement of GU. CONCLUSION Refined moxibustion at ST21 and ST36 can up-regulate the expression of EGFR and VEGF in the gastric mucosa and lessen gastric mucosal injury, which may be related to its effects in reducing GU-induced metabolic disorders, including sugar, purine, amino acid, and phospholipid metabolism and antioxidant defense system.

Abstract
BACKGROUND Axitinib monotherapy obtained approval in pre-treated mRCC patients and recently in combination with pembrolizumab or avelumab in the first-line setting. However, patient profiles that may obtain increased benefit from this drug and its combinations still need to be identified. PATIENTS AND METHODS Retrospective multicentre analysis describing clinical characteristics associated with axitinib long-responder (LR) population by comparing two extreme-response sub-groups (progression-free survival [PFS] ≥9 months vs. disease progression/refractory patients [RP]). A multivariate logistic-regression model was used to analyse clinical factors. Efficacy and safety were also analysed. RESULTS In total, 157 patients who received axitinib in second or subsequent line were evaluated (91 LR and 66 RP). Older age at start of axitinib and haemoglobin levels > LLN were independent predictive factors for LR in multivariate analyses. In LR patients, median (m) PFS was 18.1 months, median overall survival was 36.0 months and objective response rate (ORR) was 45.5%. In 59 LR patients receiving axitinib in second-line, mPFS was 18.7 months, mOS was 44.8 months and ORR was 43.9%. mOS was significantly longer in second line compared to subsequent lines (44.8 vs. 26.5 months; P = .009). In LR vs. RP, mPFS with sunitinib in first-line was correlated with mPFS with axitinib in second-line (27.2 vs. 10.9 months P < .001). The safety profile was manageable and consistent with known data. CONCLUSIONS This study confirms the long-term benefits of axitinib in a selected population, helping clinicians to select the best sequential approach and patients who could obtain a greater benefit from axitinib.

Abstract
BACKGROUND Curcumin accelerates healing of oral wounds; however, the responsible mechanisms remain underexplored. Our hypothesis is curcumin regulates the expression of wound healing-related genes in human gingival fibroblasts (hGFs). This study investigated whether curcumin regulates transforming growth factor (TGF)-β1, type I TGF-β receptor (TGF-βRI), type II TGF-β receptor (TGF-βRII), and vascular endothelial growth factor (VEGF) expression in unwounded hGFs and an in vitro hGF wound healing model. METHODS The cytotoxicity of curcumin was evaluated using the MTT assay. Unwounded hGFs were treated with non-cytotoxic concentrations of curcumin for 24 h. Gene expression was determined by quantitative polymerase chain reaction. Then, hGFs were treated with 1 µM curcumin in an in vitro wound healing model. PD98059 pretreatment was performed to determine whether extracellular signal-regulated kinase (ERK) signaling was required for regulation of gene expression by curcumin. RESULTS Curcumin at 0.1-20 µM caused no significant change in cell viability. In unwounded hGFs, curcumin had no significant effect on TGF-β1, TGF-βRI, TGF-βRII, or VEGF expression. Conversely, curcumin significantly upregulated the expression of these genes in the in vitro wound healing model. PD98059 significantly attenuated the curcumin-stimulated TGF-βRI, TGF-βRII, and VEGF expression, whereas it had no effect on TGF-β1 expression. CONCLUSIONS Curcumin upregulated TGF-β1, TGF-βRI, TGF-βRII, and VEGF expression in an in vitro hGF wound healing model. The ERK pathway is required for TGF-βRI, TGF-βRII, and VEGF induction by curcumin. Our findings support the development of curcumin as a therapeutic agent for gingival ulcers.

Abstract
Kinase insert Domain containing Receptor (KDR)/Vascular Endothelial Growth Factor Receptor (VEGFR-2) participate in endothelial dysfunction, which can lead to chronic liver disease. KDR reflects naturally against the toxicants from the damaged liver cells. Association of KDR polymorphism has been reported with many diseases including liver disease, but its role has not been described in ARV induced hepatotoxicity. Hence, we examined the exonic regions KDR (1192G/A, 1719A/T) polymorphism from 165 HIV-infected individuals (34/165 had ARV induced hepatotoxicity, 131/165 were with no hepatotoxicity) and 160 normal uninfected individuals by PCR-RFLP. In univariate analysis, KDR 1719 TT genotype presented at greater frequency from all HIV positive individuals in contrast with normal uninfected individuals (7.87% vs. 4.4%, OR = 1.72, P = 0.38). Individuals with KDR 1719 TT genotype had a risk for increasing hepatotoxicity and its severity (OR = 1.91, P = 0.38). Individuals with haplotype AT had risk for increasing hepatotoxicity and its severity (OR = 1.60, P = 0.50; OR = 2.35, P = 0.27). Whereas haplotype AA was associated with reduced risk of developing hepatotoxicity (OR = 0.40, P = 0.04). Individuals with KDR 1719 TT genotype were at greater risk of advancement of HIV disease (OR = 2.31, P = 0.23). Individuals with KDR 1719 TT genotype had more vulnerability for developing hepatotoxicity among alcohol users (OR = 2.57, P = 0.23). Individuals with KDR 1719 TT genotype were at higher risk of developing hepatotoxicity and its severity among nevirapine and alcohol consumers (OR = 2.47, P = 0.24; OR = 5.42, P = 0.42). In multivariate analysis, hepatotoxicity patients taking ART inclusive of nevirapine was associated with the severity of hepatotoxicity (OR = 4.82, P = 0.002). In conclusion, KDR 1719 TT genotype and haplotype AT may have a risk for development of hepatotoxicity and its severity. Haplotype AA may have influence to reduce the risk of developing hepatotoxicity.

Abstract
Ischemic stroke is still the major cause of disability worldwide. Although vascular endothelial growth factor (VEGF) is able to promote both angiogenesis and functional recovery, its use is limited by needle-induced injury, nonhomogenous VEGF distribution, and limited VEGF retention in the brain after intracranial or intravenous injection. Here, we first present a gelatin methacryloyl (GelMA) microneedle (MN)-based platform for the sustained and controlled local delivery of an adeno-associated virus (AAV) expressing human VEGF (AAV-VEGF) that achieves homogenous distribution and high transfection efficiency in ischemic brains. An ischemic stroke model was established in adult rats, and MNs loaded with AAV-VEGF were epicortically inserted into both the ischemic core and penumbra of these rats one day after the onset of ischemia. One week later, the inflammatory response and microneedle biocompatibility were assessed by enzyme-linked immunosorbent assay (ELISA) and immunofluorescence. Eight weeks later, angiogenesis and neural stem cell proliferation and migration were assessed. GelMA MN implantation did not elicit an obvious inflammatory response and had good biocompatibility in the brain. AAV-green fluorescent protein (GFP)-loaded MNs could achieve successful transfection and homogeneous distribution in the brain cortex three weeks postoperatively. MNs loaded with AAV-VEGF increased VEGF expression and enhanced functional angiogenesis and neurogenesis. In summary, MNs might emerge as a promising platform for delivering various therapeutics to treat ischemic stroke and repair other neurologically diseased tissues.

Abstract
Twisting of the spermatic cord is a common dangerous health problem that may be accompanied with testicular necrosis and infertility. Cilostazol (CLZ) is a selective phosphodiesterase (PDE) 3A inhibitor used for treatment of intermittent claudication. It has a great role in myocardial, spinal cord and hepatic ischaemia/reperfusion. However, till now, there are no researches evaluating its role in testicular ischaemia/reperfusion (TIR). The current work studies its capability to improve TIR induced injury with more concentration on the mechanisms involved in such effect. Four groups of animals were included: sham, TIR induced group, TIR plus CLZ low dose (10 mg/kg), TIR plus CLZ high dose (30 mg/kg). Our results proved that TIR had significant decrease of the serum ELISA of testosterone, marked disturbances in oxidative stress evaluated parameters as malondialdehyde (MDA), reduced glutathione (GSH), total antioxidant capacity (TAC), ELISA measurement of tumor necrosis factor alpha (TNFα) and interleukin 1 beta (IL1β) inflammatory mediators, apoptotic marker (caspase3) using western blotting, immunohistochemistry of hypoxia inducible factor-1α (HIF-1α) and vascular endothelial growth factor (VEGF). TIR reduced the protective agents as cyclic adenosine monophosphate (cAMP) and sirtuin-1 (SIRT1) by ELISA method with marked germinal cell apoptosis. The biochemical results were confirmed by the histopathological findings that showed marked decrease in both Johnsen's score and Cosentino's score. However, treatment with CLZ significantly reversed the profound TIR damaging effects, on the basis of its anti-inflammatory, anti-oxidant, and anti-apoptotic activities with recuperation of the testicular vascularity. Modulation of HIF/VEGF and cAMP/SIRT1 pathways showed a great role in mediating such effect.

Abstract
Vascular endothelial growth factor (VEGF) is one of the most important regulators of angiogenesis. Several single nucleotide polymorphisms (SNPs) are associated with the VEGF overexpression and tumor progression in several cancers. This study aimed to determine the association of VEGF rs833061 and rs2010963 polymorphism and their haplotypes with susceptibility to colorectal cancer (CRC) in the Iranian population. A total of 284 colorectal cancer patients (37.3% women, 62.7% men) were enrolled in this study. Healthy controls without evidence of cancer history or family cancer predispositions were frequency-matched to the cases by sex and age (± 5 years). Genotyping was performed by the Sequenom mass ARRAY method and the genotype distribution and risk estimate were analyzed by SPSS software. The correlation between the genotypes and clinicopathological parameters (Dukes stage, phenotype, location, differentiation, and tumor size) among colorectal cancer patients were investigated. We found a significant relationship, between rs833061T/C genotype and their TG haplotype with the age of diagnosis < 60; (p = 0.012, p = 0.014) and rs2010963G/C genotype with female gender and TG haplotype with third and fourth tumor stage and tumor location (p = 0.04and p = 0.047). This study showed that rs833061T/C genotype and TG haplotype increase the susceptibility to colon cancer in the Iranian population. This susceptibility has a significant relationship with the age of diagnosis and different stages of the tumor.

Abstract
The eye is regarded as an immune privileged site. Since the presence of a vasculature would impair vision, the vasculature of the eye is located outside of the central light path. As a result, many regions of the eye evolved mechanisms to deliver immune cells to sites of dysgenesis, injury, or in response to the many age-related pathologies. While the purpose of these immune responses is reparative or protective, cytokines released by immune cells compromise visual acuity by inducing inflammation and fibrosis. The response to traumatic or pathological injury is distinct in different regions of the eye. Age-related diseases impact both the anterior and posterior segment and lead to reduced quality of life and blindness. Here we focus attention on the role that inflammation and fibrosis play in the progression of age-related pathologies of the cornea and the lens as well as in glaucoma, the formation of epiretinal membranes, and in proliferative vitreoretinopathy.

Abstract
PURPOSE To evaluate the safety and efficacy of the Port Delivery System with ranibizumab (PDS) for the treatment of neovascular age-related macular degeneration (nAMD). DESIGN Phase 3, open-label, randomized, visual acuity assessor-masked noninferiority and equivalence trial. PARTICIPANTS Patients with nAMD diagnosed within 9 months of screening previously treated with and responsive to anti-vascular endothelial growth factor therapy. METHODS Patients were randomized 3:2 to treatment with the PDS with ranibizumab 100 mg/ml with fixed 24-week (Q24W) refill-exchanges (PDS Q24W) or intravitreal ranibizumab 0.5-mg injections every 4 weeks (monthly ranibizumab). MAIN OUTCOME MEASURES Primary end point was change in best-corrected visual acuity (BCVA) Early Treatment Diabetic Retinopathy Study letter (letters) score from baseline averaged over weeks 36 and 40 (noninferiority margin,-4.5 letters; equivalence margin, ±4.5 letters). RESULTS Archway enrolled 418 patients; 251 were randomized to and 248 received treatment with the PDS Q24W, and 167 were randomized to and received treatment with monthly ranibizumab. Baseline BCVA was 74.4 letters (PDS Q24W arm) and 75.5 letters (monthly ranibizumab arm; Snellen equivalent, 20/32). Adjusted mean change in BCVA score from baseline averaged over weeks 36 and 40 was +0.2 letters (standard error [SE], 0.5 letters) in the PDS Q24W arm and +0.5 letters (SE, 0.6 letters) in the monthly ranibizumab arm (difference, -0.3 letters; 95% confidence interval, -1.7 to 1.1 letters). PDS Q24W was both noninferior and equivalent to monthly ranibizumab. Of 246 PDS-treated patients assessed for supplemental ranibizumab treatment, 242 (98.4%) did not receive supplemental ranibizumab treatment before the first refill-exchange procedure, including 4 patients who discontinued treatment before the first refill-exchange procedure. Prespecified ocular adverse events of special interest were reported in 47 patients (19.0%) in the PDS Q24W arm and 10 patients (6.0%) in the monthly ranibizumab arm, which included, in the former arm, 4 (1.6%) endophthalmitis cases, 2 (0.8%) retinal detachments, 13 (5.2%) vitreous hemorrhages, 6 (2.4%) conjunctival erosions, and 5 (2.0%) conjunctival retractions. Most ocular adverse events in the PDS Q24W arm occurred within 1 month of implantation. CONCLUSIONS Archway met its primary objective and PDS Q24W demonstrated noninferior and equivalent efficacy to monthly ranibizumab, with 98.4% of PDS-treated patients not receiving supplemental treatment in the first 24-week interval.

Abstract
BACKGROUND Conbercept, as a novel vascular endothelial growth factor (VEGF) inhibitor, was approved for the treatment of neovascular age-related macular degeneration (nAMD) in China. OBJECTIVE This study aimed to compare the efficacy and safety between conbercept and ranibizumab in patients with nAMD. METHODS Several databases (PubMed, Web of Science, China National Knowledge Infrastructure, and WANFANG) were searched for the results of studies describing conbercept and ranibizumab for the treatment of nAMD. Sixteen randomized controlled trials including 1,224 eyes met our search criteria and were assessed. RESULTS Conbercept and ranibizumab had comparable effects on improving visual acuity at 3 months (standardized mean difference [SMD]: -0.19; 95% confidence interval [CI]: -0.46 to 0.08; p = 0.17) and 6-12 months (SMD: -0.01; 95% CI: -0.20 to 0.18; p = 0.90). At 3 months and 6-12 months, the differences in the change of central macular thickness in conbercept and ranibizumab groups were 1.06 μm (95% CI: -3.52 to 5.64; p = 0.65) and -0.12 μm (95% CI: -9.26 to 9.02; p = 0.98). In the short term, there was no significant difference between the 2 groups with respect to ocular adverse events (odds ratio [OR]: 0.86; 95% CI: 0.46-1.61; p = 0.63). No significant differences were observed in the recovery rate of choroidal neovascularization leakage between conbercept and ranibizumab at both 3 months (OR: 1.49; 95% CI: 0.83-2.68; p = 0.18) and 6-12 months (OR: 0.66; 95% CI: 0.18-2.43; p = 0.53). There were significant differences between conbercept and ranibizumab in terms of decreasing intraocular pressure (weighted mean difference [WMD]: -1.74; 95% CI: -2.28 to -1.20; p < 0.00001), the plasma VEGF level (WMD: -21.49; 95% CI: -26.28 to -16.70; p < 0.00001), and the C-reactive protein level (WMD: -1.16; 95% CI: -1.45 to -0.87; p < 0.00001) in the short term. CONCLUSION Conbercept was similar to ranibizumab in terms of efficacy and safety for the treatment of nAMD in China. Further studies with longer term observation are needed to support this conclusion.

Abstract
Background & Objective: Vascular Endothelial Growth Factor (VEGF) is one of the newer molecular markers that acts as a central mediator of tumor angiogenesis and is essential for tumor growth, progression, and metastasis. So anti-angiogenic drugs can be used as anticancer therapy. Treatments with anti-VEGF (Bevacizumab) therapy have been proved to improve relapse-free survival in many tumors. Urinary bladder tumor has become emerging cancer globally among elderly individuals. So, the identification and development of novel biomarkers for effective treatment of urinary bladder carcinoma is essential. The present study aimed to investigate the immunohistochemical expression of VEGF in urothelial carcinoma of urinary bladder and to assess its association with tumor grade and muscle invasiveness. Methods: This cross-sectional study was conducted in the Department of Pathology, Chittagong Medical College, Chattogram from September 2018 to August 2020. Fifty-six formalin-fixed paraffin-embedded tissue blocks of urinary bladder carcinoma were prepared for both histopathological and immunohistochemical examination. Each slide was evaluated by at least two pathologists. Results: Weak to strong positive expression of VEGF were observed in 52 cases (92.86%). The proportion of tumors positive for VEGF expression was higher among patients with high grade and non-muscle invasive bladder carcinoma. Conclusion: We found that VEGF expression has a significant association with tumor grade and an inverse association with muscle invasion. These findings may be useful for selecting the subset of patients likely to respond to anti-VEGF targeted therapy.

Abstract
This study aimed to assess the maternal features, Vascular Endothelial Growth Factor (VEGF) and Placenta Growth Factor (PLGF) in the Placenta Accreta Spectrum (PAS); then, to determine a predictive value of VEGF and PLGF in the PAS. This prospective case-control study was conducted on 90 pregnant women including 45 PAS, and 45 Normal Placenta (NP). Maternal age, gravidity, C/S, and serum levels of VEGF and PLGF were assessed between NP and PAS, and among NP and PAS sub-groups, including Placenta Accreta (PA), Placenta Increta (PI), and Placenta Percreta (PP). The Multi-gravidity, previous C/S, maternal age, and serum level of PLGF were significantly higher in the PAS group compared to the NP group OR = 42, 8.1, 1.17, and 1.002 (p-value <.05 for all); however, there was no difference regarding serum level of VEGF (p-value >.05). The same differences were seen among NP with PA, PI, and PP sub-groups (p-value <.05 for all, but p-value >.05 for VEGF). Placenta Previa was uniformly distributed across the PAS sub-groups (p-value >.05), also the VEGF and PLGF serum levels did not differ between PAS with Previa and PAS without Previa groups (p-value >.05). A valid cut-off point for PLGF was reported at 63.55. A predictive value of PLGF for the PAS patients is presented enjoying high accuracy and generalisability for the study population.Impact statementWhat is already known on this subject? The Placenta Accreta Spectrum (PAS), in which the placenta grows too deep in the uterine wall, is responsible for maternal-foetal morbidity and mortality worldwide; so, the antenatal diagnosis of PAS is an important key to improve maternal-foetal health. Normal placental implantation requires a fine balance among the levels of angiogenic and anti-angiogenic factors, such as the Placenta Growth Factor (PLGF), the Vascular Endothelial Growth Factor (VEGF), and soluble Fms-like tyrosine kinase-1. However, there is still controversy regarding The PLGF and VEGF level changes in PAS patients.What do the results of this study add? Despite traditional measuring the levels of PLGF and VEGF from the placenta at the time of delivery; in this study including 90 participants (28-34 weeks of gestation) the maternal serum levels of PLGF and VEGF were measured in advance (temporality causation), resulted in presenting a more valid cut-off point for PLGF in PAS group. In addition, the serum level of PLGF was significantly higher in the PAS and PAS sub-groups compared to the Normal Placenta group. Also, the Previa status of PAS patients did not affect the VEGF and PLGF serum levels.What are the implications of these findings for clinical practice and/or further research? PLGF cut-off point derived from the maternal serum level could predict PAS validly and, if used as a screening test in an earlier pregnancy, the maternal-foetal morbidity and mortality would decrease.

Abstract
PURPOSE To evaluate morphologic changes of choroidal neovascularization (CNV) on optical coherence tomography angiography (OCTA) during the nonexudative period and to correlate the features and timing of recurrence in neovascular age-related macular degeneration. (AMD). METHODS Two hundred thirty-eight eyes with type 1 CNV were retrospectively reviewed. For cases with exudative recurrence, OCTA images were tracked for analysis between the recurrences. Qualitative parameters of morphologic changes of CNV on OCTA, including tiny branching vessels, anastomotic loops, peripheral vascular arcade, and perilesional halo, were correlated with the features of exudative recurrence. RESULTS Exudative recurrence was identified in 163 cases, and among them, nonexudative morphological changes in CNV were identified using OCTA in 45 cases. For the cases with nonexudative changes on OCTA, exudative recurrence eventually developed within 0.5-3.5 months (mean, 2.3 ± 2.0 months) after identifying morphologic changes OCTA. The following changes in CNV were revealed on OCTA: tiny branching vessels in 53.3% (24/45) of cases, anastomotic loops in 40.0% (18/45), peripheral vascular arcades in 44.4% (20/45), and perilesional halo in 35.6% (16/45). Among the morphologic parameters, development of tiny branching vessels was significantly associated with early exudative recurrence (1.5 ± 1.2 months, p = 0.019), higher incidence of intraretinal fluid (IRF) (p = 0.016), and subretinal or subretinal pigment epithelial hemorrhage (p = 0.023) at recurrence, compared with other morphologic changes. CONCLUSION Development of tiny branching vessels of CNV on OCTA during the nonexudative period was associated with early exudative recurrence, including IRF or hemorrhage. Identifying the nonexudative changes of CNV on OCTA might predict exudative recurrence and provide additional parameters for monitoring neovascular AMD.

Abstract
BACKGROUND Colorectal cancer (CRC) is a malignant tumor with high morbidity and mortality worldwide, representing a major public health problem. It ranks the third among newly diagnosed cancers and is the fourth cause of cancer death. There is currently an urgent need to find effective indexes for predicting liver metastasis after CRC surgery. Early detection of CRC liver micrometastasis is helpful for effective intervention and comprehensive treatment, which will greatly improve the prognosis of patients.
AIM To explore the prognostic value of changes in portal vein thromboxane A2 (TXA2), vascular endothelial growth factor (VEGF), and carcinoembryonic antigen (CEA) levels in patients with CRC after surgery.
METHODS From May 2017 to November 2019, 112 CRC patients at our hospital were selected and divided into either an observation group (liver metastasis, n = 21) or a control group (no liver metastasis, n = 91) according to whether there were liver metastases 6 mo after surgery. The clinical data and the levels of TXA2, VEGF, and CEA in portal vein blood were compared between the two groups, and the influencing factors of liver metastasis in patients with CRC were analyzed. The correlation between the levels of portal venous blood indicators and clinicopathological parameters, their predictive value for postoperative liver metastasis in patients with CRC, and their correlation with the prognosis were evaluated.
RESULTS The levels of TXA2, VEGF, and CEA in portal vein blood were significantly higher in the observation group than in the control group (P < 0.05). Age, lesion size, histological grade, T stage, regional lymph node metastasis, vascular tumor thrombosis, surgical methods, adjuvant chemotherapy, and portal vein blood TXA2, VEGF, and CEA levels were all influential factors for postoperative liver metastasis in CRC patients (P < 0.05). Portal vein blood TXA2, VEGF, and CEA levels in patients with liver metastases after CRC were positively correlated with age, lesion size, T stage, regional lymph node metastasis, and tumor thrombus, and negatively correlated with histological grade (P < 0.05). The AUC of combined detection of TXA2, VEGF, and CEA in the prediction of postoperative liver metastasis in CRC patients was the largest (0.929). There was no statistically significant difference in the postoperative survival rate of patients with high levels of TXA2, VEGF, and CEA in portal vein blood and those with low levels (P > 0.05).
CONCLUSION The high expression of TXA2, VEGF, and CEA in portal vein blood may be involved in the process of liver metastasis after CRC. The combined detection of the above indicators can provide data support for clinical prediction of liver metastasis and prognosis in patients with CRC after surgery.

Abstract
BACKGROUND Polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes (POEMS) syndrome is a rare paraneoplastic syndrome caused by a plasma cell proliferative disorder. The syndrome is characterized by elevated plasma cells, platelets, and vascular endothelial growth factor levels. Although heart disease rarely occurs in POEMS syndrome, the death rate increases sharply after heart failure. We report a patient who initially presented with an endocrine disease and developed congestive heart failure related to POEMS syndrome 9 years later.
CASE SUMMARY A 23-year-old woman with no history of menstruation and a 9-year history of type I diabetes reported feeling breathless after activities. She could not lie down and rest at night. Three months prior, she experienced pain and increased tension in her left thigh accompanied by tenderness and edema in both lower extremities. The chief complaint upon hospital admission was that blood sugar has increased for more than 9 years, pain in the left thigh, and edema in both legs for more than 2 mo. After a multisystem evaluation, she was diagnosed with POEMS syndrome. Her echocardiogram showed left ventricular dilation with systolic dysfunction, and the left ventricular ejection fraction was only 38% with severely elevated brain natriuretic peptide. She received a combination of dexamethasone and thalidomide for 1 mo, but her symptoms did not improve. Therefore, we added a two-per-week bortezomib injection. After 2 wk, the patient’s heart function had improved significantly.
CONCLUSION This case provides information about the treatment of POEMS syndrome with complications and highlights the challenges of developing a standardized treatment.

Abstract
Purpose To report a case of branch retinal vein occlusion (BRVO) in which rapid formation of macular pucker was observed after an intravitreal ranibizumab (IVR) injection. Observations A 66-year-old patient was referred to our department for the treatment of macular edema (ME) secondary to BRVO in the left eye. On the initial visit, widespread retinal hemorrhage was observed around the superior temporal vascular arcade, and the decimal best-corrected visual acuity (BCVA) was 0.7 (Snellen equivalent 20/29) in the left eye. Optical coherence tomography demonstrated a thin epiretinal membrane (ERM) accompanied by diffuse retinal thickening. A 0.5 mg IVR injection was administered for the treatment of ME and prompt resolution of retinal hemorrhage. Fourteen days after IVR administration, the ERM had progressed remarkably into a macular pucker and had spread from the superior macula to the equator, accompanied by partial tractional retinal detachment. We performed pars plana vitrectomy combined with encircling scleral buckling. Three months after the surgery, the decimal BCVA was 0.4 (Snellen equivalent 20/50), the retina was attached, and no recurrence of ME or proliferation was observed. Conclusions and Importance IVR for BRVO may cause rapid formation of macular pucker in the eye, especially in the presence of pre-existing ERM. Careful observation of patients with BRVO is essential after administration of anti-VEGF agents, especially in eyes with pre-existing ERM.

Abstract
BACKGROUND Elevated preoperative plasma levels of the angiogenesis-related marker VEGF have been associated with worse oncological outcomes in various malignancies. OBJECTIVE To investigate the predictive/prognostic role of VEGF in patients with urothelial carcinoma of the bladder (UCB) treated with radical cystectomy (RC). DESIGN, SETTING, AND PARTICIPANTS VEGF plasma levels were measured preoperatively in 1036 patients with UCB who underwent RC. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The correlation between plasma VEGF levels and pathological and survival outcomes was assessed using logistic regression and Cox regression analyses. Discrimination was assessed using the concordance index (C index). The clinical net benefit was evaluated using decision curve analysis (DCA). RESULTS AND LIMITATIONS Patients with higher pretreatment plasma VEGF levels had poorer recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS) according to log-rank tests (all p < 0.001). Higher VEGF levels were not independently associated with higher risk of lymph node metastasis, ≥pT3 disease, or non-organ-confined disease (all p > 0.05). Preoperative plasma VEGF levels were independently associated with RFS, CSS, and OS in preoperative and postoperative multivariable models. However, in all cases the C index increased by <0.02 and there was no improvement in net benefit on DCA. A limitation is that none of the patients received current elements of standard of care such as neoadjuvant chemotherapy. CONCLUSIONS Elevated plasma VEGF levels were associated with features of biologically and clinically aggressive disease such as worse survival outcomes among patients with UCB treated with RC. However, VEGF appears to have relatively limited incremental additive value in clinical use. Further study of VEGF for UCB prognostication is warranted before routine use in clinical algorithms. PATIENT SUMMARY Currently available models for predicting outcomes in bladder cancer are less than optimal. A protein called vascular endothelial growth factor (VEGF), which is a marker of the formation of blood vessels (angiogenesis), may have a role in predicting survival outcomes in bladder cancer. TAKE HOME MESSAGE Elevated plasma VEGF levels are associated with worse survival outcomes for patients with urothelial carcinoma of the bladder (UCB) treated with radical cystectomy. VEGF could be used as a part of a biomarker panel to enhance tools currently used for risk stratification for patients with UCB.

Abstract
OBJECTIVES Vascular endothelial growth factor A (VEGFA) is one of the major factors initiating and regulating angiogenesis. LncRNA taurine up-regulated gene 1 (TUG1) has been implicated in the pathological neovascularization. The aim of this study is to explore the function of TUG1 in regulating VEGFA-mediated angiogenesis in endothelial cells. METHODS A total of 12 corneal neovascularization (CRNV) samples were collected form patient undergoing corneal transplantation at Tongji Hospital, Wuhan, China. qRT-PCR and Western blotting were performed to examine gene expression and protein levels. Human umbilical vein endothelial cells (HUVECs) were used as an in vitro angiogenesis model. CCK-8 proliferation assay was used to determine cell proliferation capacity and wound healing was performed to analyze cell migration ability. Dual luciferase reporter assay was used for functional interaction validation between miR-505-3p and its targets. The in vitro angiogenic potential was evaluated by tube formation assay. RESULTS TUG1 and VEGFA were upregulated in CRNV tissues and VEGFA-treated HUVECs. TUG1 knockdown inhibited proliferation, migration and tube formation capacity of HUVECs. TUG1 regulated the angiogenesis of HUVECs by modulating VEGFA expression through targeting miR-505-3p. CONCLUSIONS Our results suggest that lncRNA TUG1 promotes the angiogenesis of HUVECs through modulating miR-505-3p/VEGFA axis.

Abstract
Pulmonary tumor thrombotic microangiopathy (PTTM) is a rare but fatal cancer-related disease. Owing to its non-specific findings, aggressive course, and lack of established treatment guidelines, only a few cases of antemortem diagnosis in long-term survivors have been reported. We aimed to report a case of uterine cervical cancer induced PTTM that was suspected based on pulmonary hypertension and successfully treated using combination chemotherapy despite of delayed diagnose. It is important to be aware that PTTM should be suspected when respiratory failure occurs in patients with unexplained pulmonary hypertension. Multidisciplinary treatments including molecular targeted therapies might be effective treatment options.

Abstract
BACKGROUND It has been reported that vascular endothelial growth factor (VEGF) is a susceptibility gene for both type 2 diabetes mellitus (T2DM) and diabetic retinopathy (DR). In response to hypoxia, VEGF mRNA levels are increased, which is mainly mediated by the binding of hypoxia-inducible factor-1 (HIF-1) and hypoxia response element upstream of the transcriptional start site of VEGF. Therefore, HIF-1a is supposed to be involved in pathology of DR.
AIM To investigate whether the polymorphisms in HIF-1a gene are associated with DR.
METHODS Two hundred and ninety-nine type 2 diabetic patients (128 males and 171 females) and 144 healthy volunteers were recruited. Mean age was 56.04 ± 21.05 years. According to the results of fundus fluorescein angiography and examination of ophthalmoscopy, patients were divided into two groups, DNR group (diabetes without retinopathy) and DR group (diabetes with retinopathy). There are 150 cases in DNR group and 149 cases in DR group. Two single nucleotide polymorphisms (SNP) of the HIF-1a gene were tested using matrix-assisted laser desorption/Ionization time of flight mass spectrometry. The frequency of genotypes and alleles, and odds ratio were measured.
RESULTS The mean age of the cases with diabetes was 55.84 ± 3.66 years, the mean age of the cases with DR was 55.97 ± 4.66 years and that of controls was 56.32 ± 4.70 years. Two variations were found in 76 patients. Rs11549465 is the change of C-T base, rs11549467 is the change of G-A base. The rs11549467 G/A genotype was 5.33% in diabetes and 6.04% in DR patients, respectively. The rs11549465 C/T genotype was 10% and 12.75% in patients with diabetes and DR. The rs11549467 A allele frequencies and rs11549465 T frequencies was similar to that of controls. Paired SNP linkage disequilibrium analysis indicated that rs11549467 was in linkage disequilibrium with rs11549465. Haplotype association analysis denoted that the haplotype association exhibited similar distribution in the patients compared to the normal controls.
CONCLUSION This study suggests that there is no relationship between the genetic variations of HIF1a and diabetes or DR.

Abstract
Systemic capillary leak syndrome (SCLS) is a syndrome caused by many reasons and without a definitive mechanism. The main diagnostic criteria of SCLS are hemoconcentration, hypoalbuminemia, and hypotension. Though most SCLS improved spontaneously within a few days, it can be life-threatening without effective treatments. In previous literature, vascular endothelial growth factor (VEGF) inhibitor had shown its potential to be an effective treatment, but the treatment outcomes were inconsistent. This article was about a 58-year-old female suffering from refractory systemic capillary leak syndrome after bone marrow transplantation and being treated with bevacizumab, a VEGF inhibitor. In comparison with other successfully treated cases, this patient received four cycles of bevacizumab treatment without symptomatic improvement and eventually died in the intensive care unit. Further studies are needed to further confirm the role of bevacizumab in the management of SCLS.

Abstract
As the highest incidence of female malignancy, breast cancer is likewise the leading cause of cancer-related deaths. The development of cancer relies on neo-vascularization, which provides sufficient nutrition and oxygen, and supplies a pathway for distant metastasis. Angiogenesis represents the formation of new blood vessels, and is a principal pathogenetic action in breast cancer. Vascular endothelial growth factor (VEGF) is a major angiogenesis regulator that modulates the maintenance and function of mature vascular networks. Therefore, the VEGF pathway is a promising oncotherapeutic target. This review elaborates an update on the prognostic value of VEGF in breast cancer, summarizes clinical experience and lessons of anti-VEGF therapeutics, meanwhile, provides an overview of biomarkers that predict the effectiveness of anti-angiogenic treatment.

Abstract
BACKGROUND Considering the vital role of vascular endothelial growth factor (VEGF) in the development of diabetic retinopathy (DR) in one hand and the frequent association between subclinical hypothyroidism (SCH) and DR on the other hand. OBJECTIVE The present study was proposed to explore the possible role of VEGF in the relation between SCH and DR, thus we investigated the relation between SCH and VEGF levels in patients with DR. METHODS Two hundred patients with DR were recruited in this study [100 patients with proliferative diabetic retinopathy (PDR) and 100 patients with non-proliferative diabetic retinopathy (NPDR)]. Patients with DR were divided into 2 groups according to thyroid function: patients with SCH or those with euthyroidism. Patients were subjected to careful history taking, and underwent clinical and ophthalmological examination. Fasting blood glucose, glycosylated hemoglobin, fasting insulin, homeostasis model assessment of insulin resistance (HOMA-IR), TSH, FT4, FT3, VEGF and thyroid volume were assessed Results: Among all the studied patients, 21.5% (43/200) had SCH. DR patients with SCH had higher age, diabetes duration, HbA1c, HOMA-IR and VEGF than those with euthyroidism. The frequency of PDR in patients with SCH was 72.1% (31/43) and 43.9% (69/157) in those with euthyroidism, whereas the frequency of NPDR in patients with SCH was 27.9 (12/43) and 56.1% (88/157) in those with euthyroidism (P < 0.003). In multivariate analysis, PDR, HOMA-IR and VEGF levels were the significant predictor variables of SCH. CONCLUSIONS Increased VEGF levels may be implicated in the relationship between SCH and DR.

Abstract
Constructing three-dimensional (3D) tissues is an important process to improve cellular functions in tissue engineering. When transplanting artificially constructed tissues, a poor vascular network restricts oxygen and nutrient supplies to the tissue cells, which leads to cell death and reduced rates of tissue engraftment. Therefore, it is necessary to develop a system that builds a vascular network within 3D tissues. Here, we developed a hypoxia-responsive gene expression system for production of an angiogenic factor, vascular endothelial growth factor (VEGF), to improve hypoxia and nutrition deficiencies inside artificial 3D tissues. We demonstrated that cells into which the hypoxia-responsive VEGF gene expression system had been introduced autonomously controlled VEGF expression in a hypoxic stress-dependent manner. Next, we confirmed that VEGF expression within a 3D cell sheet was induced in response to a hypoxic environment in vitro. The genetically modified cell sheet was subcutaneously transplanted into mice to evaluate the feasibility of the hypoxia-responsive VEGF gene expression system in vivo. The results suggest that the hypoxia-responsive VEGF gene expression system is promising to prepare artificial 3D tissues in regenerative medicine.

Abstract
POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy/edema, monoclonal plasma protein [M protein], and skin changes) is a rare paraneoplastic disorder associated with underlying plasma cell neoplasia. Although limited-stage disease can be treated with radiotherapy, treatment for the more advanced disease remains unclear. The most commonly used therapies for POEMS syndrome include alkylators and steroids, high-dose chemotherapy with autologos stem cell transplantation, lenalidomide, and bortezomib. In general, patients tend to have excellent prognosis if the diagnosis is made early and appropriate therapy is used. Here we present a systematic review of the efficacy and safety of treatment regimens used to treat POEMS syndrome in the adult population. Combinations of immunomodulatory agents with corticosteroids were most frequently utilized regimens with durable hematological and neurological responses. Combinations of proteasome inhibitors and alkylating agents with corticosteroids, although less frequently utilized, appear to have reasonable safety and efficacy profiles.

Abstract
BACKGROUND This study aimed to determine the histological, biochemical, and biomechanical efficacy of fibrin clot and vitamin C in the healing of Achilles tendon ruptures (ATR) in a rat model. METHODS 52 adult Wistar-Albino rats (300-450 g) were used in the study. 12 rats were divided into four groups as Monitor (Group I), Control (Group II), Fibrin Clot (Group III), Fibrin Clot with vitamin C (Group IV). Four rats were used for fibrin clot preparation. Fibroblast Growth Factor (FGF) and Vascular Endothelial Growth Factor (VEGF) were measured on the 3rd, 7th, 14th, and 21st days. Four rats were sacrificed on the 21st day from each group for histological evaluation. The rest of the rats were sacrificed at 42nd day, half for biomechanical and a half for histological evaluation. RESULTS The 42nd-day HSS score of group IV was significantly lower than those of group I, group II and group III (p = 0.036, p = 0.019, and p = 0.036, respectively). Group IV showed a significantly higher Maximum force N value than those of group I, group II and group III (p = 0.034, p = 0.034 and, p = 0.025, respectively). The blood FGF and VEGF levels of group III and group IV on the 3rd, 7th, 14th, and 21st days were higher than those of group I and group II (p < 0.05). CONCLUSION Fibrin clot and vitamin C produced a stronger tendon structure in terms of biomechanics while providing histological and biochemically better quality tendon healing in the surgical treatment of ATR. This model can be used to accelerate high-quality tendon healing after ATR. LEVEL OF EVIDENCE Level II, experimental study.

Abstract
BACKGROUND Positron emission tomography (PET) imaging is a non-invasive method to visualize and quantify the tumor microenvironment. This study aimed to explore the feasibility of 18F-AIF-NOTA-E[PEG4-c(RGDfk)]2 (denoted as 18F-RGD) PET quantitative parameters to distinguish the angiogenesis in colorectal cancer (CRC) mice which has different metastatic potential. METHODS Twenty LoVo and twenty LS174T of CRC liver metastases animal models were established by implantation of human CRC cell lines via intrasplenic injection. Radiotracer-based micro-PET imaging of animal model was performed and the uptake of 18F-RGD tracer in the tumor tissues was quantified as tumor-to-liver maximum or mean standardized uptake value (SUVmax or SUVmean) ratio. Pearson correlation was used to analyze the relationship between radioactive parameters and tumor markers. RESULTS The SUVmax and SUVmean ratios of LoVo model were significantly higher than those of LS174T in both liver metastasis and primary tumor lesions (P < 0.05). A significant difference was observed in both vascular endothelial growth factor (VEGF) and Ki67 expressions between LoVo and LS174T primary tumors (P < 0.05). The tumor-to-liver SUVmax or SUVmean ratio of 18F-RGD showed a moderate correlation with VEGF expression (r = 0.5700, P = 0.001 and r = 0.6657, P < 0.001, respectively), but the SUVmean ration showed a weak correlation with Ki67 expression (r = 0.3706, P < 0.05). The areas under the receiver operating characteristic (ROC) curves of 18F-RGD SUVmean ratio, SUVmax ratio for differentiating LoVo from LS174T tumor were 0.801 and 0.759, respectively. CONCLUSIONS The tumor-to-liver SUVmean ratio of 18F-RGD was a promising image parameter for the process of monitoring tumor angiogenesis in CRC xenograft mice model.

Abstract
Ovarian hyperstimulation syndrome (OHSS) is one of the most common and iatrogenic complications of in vitro fertilization therapy, which is an exaggerated response to excess hormones resulting in the development of a large number of maturing follicles. Although the complications of and reasons for the condition are well known, the overall histopathological effects on systemic organs and the extent of the damage have not been fully elucidated. Besides, the mechanism that underlies the situation is not very well known. The aim of the present work was to analyse the histopathological effects of OHSS on reproductive (uterus and ovary) and vital organs (liver and kidney) and the possible role of the VEGF-PKA pathway in triggering the condition. Balb/c mice were used to establish an OHSS model. The OHSS group were injected with overdose PMSG while the normal responder group were injected with an optimal dose. Histopathological evaluation was utilised in the liver, kidney, ovary, and uterus stained with hematoxylin and eosin, Masson's trichrome, and periodic acid-Schiff stain. The expression profiles of VEGF (vascular endothelial growth factor), PKA (protein kinase A), and p-PKA (an activated form of PKA) were detected with immunohistochemistry and Western blotting. OHSS was demonstrated to have a negative histopathological effect on all of the organs analysed. These effects were associated with an overall increase in the expression levels of VEGF, PKA, and p-PKA. OHSS has a serious histopathological negative effect on the systemic and reproductive organs and is proven to affect overall health, and thus should be considered a dangerous complication during ART techniques. The activation of the VEGF-PKA pathway, which is indicated by the expression levels of VEGF, PKA, and p-PKA, is demonstrated to accompany this complication, which should be further elucidated to understand the mechanisms underlying the condition.
