Abstract
OBJECTIVES This study provided information about sleep disruption, particularly its prevalence and severity among Hong Kong Chinese childhood cancer survivors. Additionally, we identified the factors influencing sleep disruption and explored how fatigue, depressive symptoms and physical activity (PA) affect sleep disruption. METHODS 402 survivors 6-18 years old and 50 age- and gender-matched healthy counterparts were assessed for depressive symptoms, fatigue, PA and subjective sleep quality. Demographic and clinical information were collected. Multiple logistic regression analyses were conducted to identify any factors contributing to poor sleep. RESULTS Mean scores of depressive symptoms, fatigue for children and that for adolescents, and PA in survivors were 16.1 (SD=11.1), 24.6 (SD=10.3), 27.7 (SD=7.8) and 3.08 (SD=2.9), respectively. 44.8% of the survivors were poor sleepers, which was more that in healthy counterparts. The three most common sleep problem were prolonged sleep latency (31.9%), daytime dysfunction (23.4%) and sleep disturbance (22.9%). The time since last treatment (children: AOR=0.54, 95%CI=0.30-0.96, p=.04; adolescents: AOR=0.80, 95%CI=0.70-0.92, p<.01) and PA levels (children: AOR=0.46, 95%CI=0.260-0.82, p=.01; adolescents: AOR=0.70, 95%CI=0.49-0.98, p=.04) were negatively associated with sleep disruption, while depressive symptoms (children: AOR=1.31, 95%CI=1.04-1.64, p=.02; adolescents: AOR=1.07, 95%CI=1.01-1.13, p=.03), fatigue (children: AOR=1.15, 95% CI=1.00-1.31, p=.04; adolescents: AOR=1.08, 95%CI=1.02-1.15, p=.01), number of treatment received (children:AOR=16.56, 95% CI=1.27-216.82, p=.03; adolescents: AOR=7.30, 95%CI=2.36-22.56, p<.01) and co-sleeping (children: AOR=29.19, 95%CI=1.65-511.57, p=.02; adolescents: AOR=4.63, 95%CI=1.22-17.61, p=.02) were positively associated with sleep disruption. CONCLUSION PA made the largest contribution to reduce sleep disruption. It is crucial to advocate for the adoption and maintenance of PA in survivorship. This article is protected by copyright.

Abstract
AIMS To investigate genotype and phenotype of congenital nephrogenic diabetes insipidus caused by AVPR2 mutations, which is rare and limitedly studied in Chinese population. METHODS 88 subjects from 28 families with NDI in a department (Beijing, PUMCH) were screened for AVPR2 mutations. Medical records were retrospectively reviewed and characterized. Genotype and phenotype analysis was performed. RESULTS 23 AVPR2 mutations were identified, including six novel mutations (p.Y117D, p.W208R, p.L313R, p.S127del, p.V162Sfs*30 and p.G251Pfs*96). The onset-age ranged from 1 week to 3 years. Common presentations were polydipsia and polyuria (100%) and intermittent fever (57%). 21% and 14% of patients had short stature and mental impairment. Urine SG and osmolality were decreased, while serum osmolality and sodium were high. Urological ultrasonography results showed hydronephrosis of the kidney (52%), dilation of the ureter (48%), and thickened bladder wall or increased residual urine (32%), led to intermittent urethral catheterization (7%), cystostomy (11%) and binary nephrostomy (4%). Urological defects were developed in older patients. Genotype and phenotype analysis revealed patients with non-missense mutations had higher levels of serum sodium than missense mutations. CONCLUSION In the first and largest case series of NDI caused by AVPR2 mutations in Chinese population, we established genetic profile and characterized clinical data, reporting six novel mutations. Further, we found genotype was associated with phenotype. This knowledge broadens genotype and phenotype spectrum of rare congenital NDI caused by AVPR2 mutations, and provides basis for studying molecular biology of AVPR2.

Abstract
With the aim of exploring the potential application of a novel chitosan oligosaccharide derivative (COS-All-Tio) in shrimp preservation, six dominant spoilage bacteria in the spoiled shrimp (Penaeus vannamei) were isolated and identified as Shewanella putrefaciens (RMS1), S. putrefaciens (S2), Pseudomonas weihenstephanensis (P1), P. gessardii (P2), Aeromonas bestiarum (A1) and Aeromonas molluscorum (A2). The antibacterial effect of COS-All-Tio against the six bacterial isolates were studied. Bacterial inhibition zone determination, and minimum inhibitory concentration and minimum bactericidal concentration assays indicated that the antibacterial activity of COS-All-Tio was greatly improved when compared to that of chitosan oligosaccharide (COS). The antibacterial mechanism investigation against S. putrefaciens (RMS1) revealed that COS-All-Tio could inhibit bacterial growth by influencing of membrane integrity. Such disturbance of membrane structure resulted in the leakage of intracellular substance of the bacteria. A strong synergistic antibacterial effect against S. putrefaciens (RMS1) was observed when COS-All-Tio was used in combination with food preservatives (e.g. ε-polylysine hydrochloride). Therefore, COS-All-Tio might have potential in shrimp preservation.

Abstract
Metformin, a drug prescribed to treat type 2 diabetes, has been reported to possess antitumor activity via immunity activation. However, the influence of metformin on natural killer (NK) cells is not fully understood. Here, we investigated whether metformin exerts a potent anticancer effect by activating NK cells. The results showed that sustained exposure to metformin enhances the cytolytic activity of NK-92 cells. Moreover, this enhancement of cytotoxicity by metformin was also observed in NK cells from healthy peripheral blood and cancer patient ascites. Mechanistically, metformin induced activation of the JAK1/2/3/STAT5 and AKT/mTOR pathways in a p38 MAPK-dependent manner rather than an AMPK-dependent manner. In vivo experiments, metformin also improved cancer surveillance of NK cells in mouse models of lymphoma clearance and metastatic melanoma. Additionally, combination treatment with metformin and anti-PD-1 antibodies increased the therapy response rates of B16F10 melanoma. Moreover, metformin treatment increased NK cell and T cell infiltration in tumors. Therefore, these results provide a deeper understanding of metformin on the effector function of NK cells and will contribute to the development and applications of metformin in cancer treatment strategies.

Abstract
Objective: To investigate the present situation of unintended pregnancy within two years postpartum and its influencing factors in China. Methods: Participants who delivered a live birth at 60 hospitals in 15 provinces in the eastern, central and western regions of China during July 2015 to June 2016 were interviewed by using structured questionnaire. Information on occurrence of unintended pregnancy within 2 years after delivery, postpartum contraceptive use, sexual resumption, breastfeeding, and women's socio-demographic characteristics, and so on, were collected. Life-table analysis, cluster log-rank tests and a 2-level Cox regression model were used for data analysis. Results: A total of 18 045 postpartum women were investigated. The cumulative 1- and 2-year unintended pregnancy rates after delivery were 5.3% (95%CI: 4.5%-6.1%) and 13.1% (95%CI: 11.3%-14.8%), respectively. Cox regression model analysis showed that the risk of unintended pregnancy within 2 years postpartum were increased in younger women, ethnic minorities, women with abortion history, and those who had a vaginal delivery with short lactation time and late postpartum contraceptive initiation (all P<0.01). The risk of postpartum unintended pregnancy was not associated with geographic regions and hospitals where women gave a birth (all P>0.05). Conclusions: In China, the risk of unintended pregnancy within 2 years after delivery is relatively high. Service institutions and service providers should improve the quality of postpartum family planning services, promote the use of high effect contraceptive methods, and educate women to use a method at the time of their sexual resumption or even before.

Abstract
Background Multiple treatments for early–moderate grade symptomatic haemorrhoids currently exist, each associated with their respective efficacy, complications, and risks. The aim of this study was to compare the relative clinical outcomes and effectiveness of interventional treatments for grade II–III haemorrhoids. Methods A systematic review was conducted according to PRISMA criteria for all the RCTs published between 1980 and 2020; manuscripts were identified using the MEDLINE, Embase, and CENTRAL databases. Inclusion criteria were RCTs comparing procedural interventions for grade II–III haemorrhoids. Primary outcomes of interest were: symptom recurrence at a minimum follow-up of 6 weeks, postprocedural pain measured on a visual analogue scale (VAS) on day 1, and postprocedural complications (bleeding, urinary retention, and bowel incontinence). After bias assessment and heterogeneity analysis, a Bayesian network meta-analysis was performed. Results Seventy-nine RCTs were identified, including 9232 patients. Fourteen different treatments were analysed in the network meta-analysis. Overall, there were 59 RCTs (73 per cent) judged as being at high risk of bias, and the greatest risk was in the domain measurement of outcome. Variable amounts of heterogeneity were detected in direct treatment comparisons, in particular for symptom recurrence and postprocedural pain. Recurrence of haemorrhoidal symptoms was reported by 54 studies, involving 7026 patients and 14 treatments. Closed haemorrhoidectomy had the lowest recurrence risk, followed by open haemorrhoidectomy, suture ligation with mucopexy, stapled haemorrhoidopexy, and Doppler-guided haemorrhoid artery ligation (DG-HAL) with mucopexy. Pain was reported in 34 studies involving 3812 patients and 11 treatments. Direct current electrotherapy, DG-HAL with mucopexy, and infrared coagulation yielded the lowest pain scores. Postprocedural bleeding was recorded in 46 studies involving 5696 patients and 14 treatments. Open haemorrhoidectomy had the greatest risk of postprocedural bleeding, followed by stapled haemorrhoidopexy and closed haemorrhoidectomy. Urinary retention was reported in 30 studies comparing 10 treatments involving 3116 participants. Open haemorrhoidectomy and stapled haemorrhoidopexy had significantly higher odds of urinary retention than rubber band ligation and DG-HAL with mucopexy. Nine studies reported bowel incontinence comparing five treatments involving 1269 participants. Open haemorrhoidectomy and stapled haemorrhoidopexy had the highest probability of bowel incontinence. Conclusion Open and closed haemorrhoidectomy, and stapled haemorrhoidopexy were associated with worse pain, and more postprocedural bleeding, urinary retention, and bowel incontinence, but had the lowest rates of symptom recurrence. The risks and benefits of each treatment should be discussed with patients before a decision is made.

Abstract
Background Sleep disruption is a prevalent symptom reported by survivors of childhood cancer. However, there is no validated instrument for assessing this symptom in this population group. To bridge the literature gap, this study translated and adapted the Pittsburgh Sleep Quality Index (PSQI) for Hong Kong Chinese cancer survivors and examined its psychometric properties and factor structure. Methods A convenience sample of 402 Hong Kong Chinese childhood cancer survivors aged 6–18 years were asked to complete the Chinese version of the PSQI, Center for Epidemiologic Studies Depression Scale for Children (CES-DC), Fatigue Scale-Child (FS-C)/Fatigue Scale-Adolescent (FS-A), and Pediatric Quality of Life Inventory (PedsQL). To assess known-group validity, 50 pediatric cancer patients and 50 healthy counterparts were recruited. A sample of 40 children were invited to respond by phone to the PSQI 2 weeks later to assess test–retest reliability. A cutoff score for the translated PSQI used with the survivors was determined using receiver operating characteristic analysis. Results The Chinese version of the PSQI had a Cronbach alpha of 0.71, with an intraclass correlation coefficient of 0.90. Childhood cancer survivors showed significantly lower mean PSQI scores than children with cancer, and significantly higher mean scores than healthy counterparts. This reflected that childhood cancer survivors had a better sleep quality than children with cancer, but a poorer sleep quality than healthy counterparts. We observed positive correlations between PSQI and CES-DC scores and between PSQI and FS-A/FS-C scores, but a negative correlation between PSQI and PedsQL scores. The results supported that the Chinese version of the PSQI showed convergent validity. Confirmatory factor analysis showed that the translated PSQI data best fit a three-factor model. The best cutoff score to detect insomnia was 5, with a sensitivity of 0.81 and specificity of 0.70. Conclusion The Chinese version of the PSQI is a reliable and valid instrument to assess subjective sleep quality among Hong Kong Chinese childhood cancer survivors. The validated PSQI could be used in clinical settings to provide early assessments for sleep disruption. Appropriate interventions can therefore be provided to minimize its associated long-term healthcare cost. Trial registration This study was registered in ClinicalTrials.gov with the reference number NCT03858218.

Abstract
OBJECTIVE Long non-coding RNAs (lncRNAs) have been demonstrated to play critical roles in tumorigenesis of bladder cancer (BC). Our research aimed to explore the underlying mechanisms of lncRNA prostate cancer-associated transcript 6 (PCAT6) in BC. PATIENTS AND METHODS Real Time-quantitative Polymerase Chain reaction (RT-qPCR) was used to measure the levels of PCAT6 and miR-513a in BC tissues and cells. The Kaplan-Meier analysis was utilized to evaluate the overall survival time of BC patients. Besides, cell viability was detected by Cell Counting Kit-8 (CCK-8) assay. Cell migration and invasion were evaluated by wound healing and transwell assays. Furthermore, starBase and Dual-Luciferase reporter assay were used to determine the interaction between PCAT6 and miR-513a in BC cells. RESULTS PCAT6 expression was upregulated, while miR-513a was downregulated in BC tissues and cell lines. BC patients with high expression of PCAT6 exhibited a shorter overall survival time compared with those patients with low expression of PCAT6. Moreover, PCAT6 knockdown notably suppressed cell progression. In addition, PCAT6 inhibited miR-513a expression through direct interaction, and the silencing of PCAT6 remarkably increased the expression of miR-513a. Finally, the knockdown of miR-513a partly abolished PCAT6 silencing-induced inhibitory effects on BC progression. CONCLUSIONS Our study illustrated that PCAT6 knockdown inhibited cell progression of BC by regulating miR-513a, suggesting that PCAT6 might act as a prognostic biomarker and therapeutic target for BC patients.

Abstract
UNLABELLED By analyzing iron status of 14 ADHR patients, we found that iron deficiency was an important trigger of ADHR. Correcting iron deficiency significantly improved patients' symptoms. Meanwhile, patients' serum phosphate showed positive correlations with iron metabolism parameters and hemoglobin-related parameters, suggesting the necessity of monitoring and correcting the iron status in ADHR. INTRODUCTION Autosomal dominant hypophosphatemic rickets (ADHR) is unique for its incomplete penetrance, variety of disease onsets, and waxing and waning phenotypes. Iron deficiency is a trigger of ADHR. This study aimed to clarify the role of iron deficiency in ADHR. METHODS Data of clinical manifestations and laboratory examinations were collected from patients among eight kindreds with ADHR. Multiple regression and Pearson's correlation tests were performed to test the relationships of serum phosphate levels and other laboratory variables during the patients' follow-ups. RESULTS Among 23 ADHR patients with fibroblast growth factor 23 (FGF23) mutations, 14 patients presented with obvious symptoms. Ten patients had iron deficiency at the onset of ADHR, coinciding with menarche, menorrhagia, pregnancy, and chronic gastrointestinal bleeding. Two patients who did not have their iron status tested presented with symptoms after abortion and pregnancy in one patient each, which suggested that they also had iron deficiency at onset. Patients were treated with ferrous succinate tablets, vitamin C, and neutral phosphate and calcitriol. With correction of the iron status, the patients' symptoms showed notable improvement, with increased serum phosphate levels. Two patients' FGF23 levels also declined to the normal range. There were strong correlations between serum phosphate and serum iron levels (r = 0.7689, p < 0.0001), serum ferritin levels (r = 0.5312, p = 0.002), iron saturation (r = 0.7907, p < 0.0001), and transferrin saturation (r = 0.7875, p < 0.001). We also examined the relationships between serum phosphate levels and hemoglobin-related indices, which were significant (hemoglobin: r = 0.71, p < 0.0001; MCV: r = 0.7589, p < 0.0001; MCH: r = 0.8218, p < 0.0001; and MCHC: r = 0.7751, p < 0.0001). Longitudinal data of six patients' follow-up also showed synchronous changes in serum phosphate with serum iron levels. CONCLUSIONS Iron deficiency plays an important role in triggering ADHR. Monitoring and correcting the iron status are helpful for diagnosing and treating ADHR. Iron metabolism parameters and hemoglobin-related parameters are positively correlated with serum phosphate levels in patients with ADHR and iron deficiency, and these might serve as good indicators of prognosis of ADHR.

Abstract
AIM To investigate the value of computed tomography (CT) texture analysis (TA) and imaging features for evaluating suspected surgical superior mesenteric-portal vein (SMPV) invasion in patients with pancreatic ductal adenocarcinoma (PDAC). MATERIALS AND METHODS Fifty-four patients with PDAC in the pancreatic head or uncinate process with suspected SMPV involvement were analysed retrospectively. SMPV invasion status was identified by surgical exploration. For each patient, 396 texture features were extracted on pretreatment CT. Non-parametric tests and minimum redundancy maximum relevance were used for feature selection. A CTTA model was constructed using multivariate logistic regression, and the area under the receiver operating characteristic (AUROC) of the model was calculated. Two reviewers evaluated qualitative imaging features independently for SMPV invasion and interobserver agreement was investigated. The diagnostic performance of the imaging features and the CTTA model for SMPV invasion was compared using the McNemar test. RESULTS Of the 54 patients with PDAC, SMPV invasion was detected in 23 (42.6%). The CTTA model yielded an AUROC of 0.88 (95% confidence interval, 0.76-0.97) and achieved significantly higher specificity (0.90) than the two reviewers (0.61 and 0.65; p=0.027 and 0.043). Interobserver agreement was moderate between the two reviewers (κ = 0.517). Of the 13 cases with disagreement between the two reviewers, 11 cases were predicted accurately by the CTTA model. CONCLUSION CTTA can predict suspected SMPV invasion in PDAC and may be a beneficial addition for qualitative imaging evaluation.

Abstract
UNLABELLED There is limited evidence regarding changes in bone microstructure in patients with hypoparathyroidism. In the current study, we used a non-invasive technique to assess bone structure in hypoparathyroidism patients and discovered site-specific changes which were mainly influenced by age and menstrual status. Such changes were more prominent in the trabeculae as well as in non-surgical as opposed to post-surgical patients. INTRODUCTION Hypoparathyroidism (hypoPT) is a rare disease characterized by the lack of parathyroid hormone. There is limited evidence regarding changes in bone microstructure in patients with non-surgical hypoPT. We investigated bone microstructure of patients with non-surgical hypoPT using a non-invasive technique. METHODS Patients with hypoPT were assessed using high-resolution peripheral quantitative computed tomography (HR-pQCT) and compared to age- and sex-matched healthy controls randomly selected from a pre-existing HR-pQCT database in a cross-sectional study. Preliminary comparison between patients with different etiologies of hypoPT was performed. Associations between bone microstructure and clinical parameters were investigated using correlation and regression analyses. RESULTS A total of 94 patients with non-surgical hypoPT were recruited. Patients displayed an increase in trabecular volumetric BMD of the tibia (170.57 ± 34.32 vs. 156.48 ± 40.55 mg HA/cm3, p = 0.011) and increase in trabecular number of both the radius (1.48 ± 0.29 vs. 1.36 ± 0.22 mm-1, p = 0.003) and tibia (1.42 ± 0.23 vs. 1.24 ± 0.22 mm-1, p < 0.001) compared to healthy controls. Trabecular number was higher for non-surgical hypoPT compared to post-surgical hypoPT (1.37 ± 0.25 and 1.17 ± 0.13 mm-1, p = 0.022). Trends towards increase in cortical volumetric BMD were only present for post-menopausal female and male patients above the age of 50. For female patients, cortical volumetric BMD and area increased with age and decreased after menopause. For males, age had little influence on bone microstructure, but cortical porosity increased with longer treatment durations. CONCLUSIONS Results from this pilot study suggested that both cortical and trabecular bone were altered in this group of patients with hypoPT. Etiology for hypoPT might influence bone microstructure, mainly on trabeculae. Age, menstrual status, and treatment duration were likely to influence bone microstructure in hypoPT.

Abstract
AIM Haemorrhoidal disease can severely affect a patient's quality of life. Its classification is commonly based on morphology of the degree of prolapse; however, this does not take into account the symptoms and impact on the quality of life. The aim of this systematic review was to determine the most appropriate instruments that classify the severity of disease according to symptoms. METHOD A PRISMA-compliant search was conducted in December 2019 to identify studies that described the validation of a haemorrhoidal symptom score. The measurement properties of the scoring systems were assessed based on the consensus-based standards for the selection of health status measurement instruments (COSMIN) methodology for systematic reviews for patient-reported outcome measures. RESULTS A total of 5288 articles were identified, with five articles included. Three studies developed a scoring system based on a set of core symptoms for a cohort of patients and validated the score against treatment outcomes. One study developed a disease-specific quality of life questionnaire based on symptoms to evaluate disease burden. One study combined both quality of life and symptom measures and tested measurement properties on two cohorts of patients. Only one study demonstrated satisfactory valid, reliable and responsive measurement criteria. CONCLUSION A single study demonstrated sufficient quality in measurement properties to be recommended for clinical use. Further studies in this area should utilize consensus-based standards for designing and reporting validation research to ensure that the appropriate evidence base is acquired if any further patient-reported outcome measures are to be recommended.

Abstract
Objective: To evaluate the cost effectiveness of primary prophylaxis (PP) with pegylated recombinant human granulocyte colony stimulating factor (PEG-rhG-CSF), PP with recombinant human granulocyte colony stimulating factor (rhG-CSF) and no prophylaxis in women with early-stage breast cancer in China. Methods: Two phase Markov models were constructed for a hypothetical cohort of patients aged 45 with stage Ⅱ breast cancer. The first phase modelled costs and outcomes of 4 cycles docetaxel combined with cyclophosphamide [TC×4, febrile neutropenia (FN) risk>20%] chemotherapy, which assumptions based on literature reviews, including FN rates [base-case (deterministic sensitivity analysis range), 0.29 (0.24-0.35)] and related events [FN case-fatality, 3.4 (2.7-4.1)]. Second phase modelled the long term survival which was link with the relative dose intensity (RDI) [mortality hazard ratio (HR) of RDI < 85% vs ≥85%, 1.45 (1.00-2.32)]. Clinical effectiveness, therapeutic costs, and economic utilities were estimated from peer-reviewed publications and expert opinions in case of unavailability of published evidences. Results: Compared to rhG-CSF PP and no prophylaxis, the cost of PEG-rhG-CSF PP increased to 5 208.19 RMB and 5 222.73 RMB, respectively. The quality-adjusted life-years (QALYs) enhanced to 0.066 and 0.297, respectively. Accordingly, the incremental cost effectiveness ratios (ICERs) are 79 146.3 RMB and 17 558.77 RMB per QALY, which were both below the willingness to pay (WTP) threshold of three times GDP per capita (18, 000 RMB) recommended by the WHO. Sensitivity analysis suggested that the more clinically effective the primary prophylaxis with PEG-rhG-CSF is, the more cost-effective primary prophylaxis with PEG-rhG-CSF will be. And the lower the mortality HR of RDI<85% vs ≥85% is, the more cost-effective primary prophylaxis with PEG-rhG-CSF will be. Conclusion: Although the cost of PP PEG-rhG-CSF is higher, considering the additional benefits, the administrating of PP PEG-rhG-CSF is likely to be a cost-effective alternative to PP rhG-CSF and no prophylaxis in patients with early stage breast cancer whose FN risks are more than 20% in China.

Abstract
OBJECTIVE The study aim was to investigate how the integrated experiential training programme with coaching could motivate children undergoing cancer treatment to adopt and maintain physical activity. METHODS A descriptive phenomenological approach was used. A purposive sample of 23 children and their parents participated in one-to-one 25-30-minute semistructured interviews. Interviews were tape-recorded and transcribed. Colaizzi's method of descriptive phenomenological data analysis was used. RESULTS The integrated programme motivated children with cancer by increasing children's and parents' knowledge of physical activity, enhancing confidence in physical activity and improving physical and psychological well-being. Moreover, the programme provided children with encouragement and psychological support through coach companionship. The programme also facilitated children's participation in physical activity and modified perceptions of physical activity. CONCLUSION This study addressed a gap in the literature by exploring how an integrated programme promoted and maintained physical activity in childhood cancer patients. PRACTICE IMPLICATIONS The integrated experiential training programme is feasible and can be easily sustained. Future studies could extend the programme beyond aspects of physical activity to help people change their health practices and maintain a healthy lifestyle.

Abstract
A great deal of evidence has shown that anti-angiogenic molecules and antibodies targeting the VEGF-A/VEGFRs signal pathway can also reverse tumor-induced immunosuppression to an extent. VEGF165b, an anti-angiogenic VEGF-A isoform, has demonstrated capacity as an efficacious anti-tumor therapy in mice as an anti-angiogenic agent. However, whether VEGF165b also plays an immunomodulatory role in anti-tumor field remains unclear. mVEGF165b effect on regulatory T cells (Tregs) in vitro were evaluated using flow cytometry and Cell Counting Kit-8 (CCK-8) methods. Its effects on Tregs (or Foxp3 expressing cells) and myeloid-derived suppressor cells (MDSCs) were analyzed in vivo using flow cytometry and immunostaining techniques. In this study, we found VEGF165b and its mutant (its half-life in plasma was extended 10 times while retaining its bioactivity; the VEGF165b mutant is called mVEGF165b for short) inhibited the proliferation of Tregs in vitro. In addition, mVEGF165b dramatically inhibited the accumulation of MDSCs and Tregs (or Foxp3 expressing cells) in the spleen and tumor in tumor-bearing mice. In conclusion, our findings demonstrated for the first time that VEGF165b and its mutant has immunoregulatory functions. It may be used as a potential immunomodulatory agent, beyond its anti-angiogenic capacities, in cancer therapies.
