Abstract
Aging leads to a decrease in muscle function, mass, and strength in skeletal muscle of animals and humans. The transcriptome identified activation of the JAK/STAT pathway, a pathway that is associated with skeletal muscle atrophy, and endurance training has a significant effect on improving sarcopenia; however, the exact mechanism still requires further study. We investigated the effect of endurance training on sarcopenia. Six-month-old male SAMR1 mice were used as a young control group (group C), and the same month-old male SAMP8 mice were divided into an exercise group (group E) and a model group (group M). A 3-month running exercise intervention was performed on group E, and the other two groups were kept normally. Aging caused significant signs of sarcopenia in the SAMP8 mice, and endurance training effectively improved muscle function, muscle mass, and muscle strength in the SAMP8 mice. The expression of JAK2/STAT3 pathway factor was decreased in group E compared with group M, and the expression of SOCS3, the target gene of STAT3, and NR1D1, an atrophy-related factor, was significantly increased. Endurance training significantly improved the phenotypes associated with sarcopenia, and the JAK2/STAT3 pathway is a possible mechanism for the improvement of sarcopenia by endurance training, while NR1D1 may be its potential target. Keywords: Sarcopenia, Endurance training, Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3), Nuclear receptor subfamily 1, group D member 1 (Nr1d1).

Abstract
BACKGROUND AND PURPOSE Conventionally, early treatment response to stereotactic radiotherapy in intracranial tumors is often determined by structural MR imaging. Tissue sodium concentration is altered by cellular integrity and energy status in cells. In this study, we aimed to investigate the feasibility of sodium MR imaging at 7T for the preliminary evaluation of radiotherapeutic efficacy for intracranial tumors. MATERIALS AND METHODS Data were collected from 16 patients (12 men and 4 women, 24-75 years of age) with 22 intracranial tumors who were treated with stereotactic radiation therapy using CyberKnife at our institution between December 1, 2016, and August 15, 2019. Sodium MR imaging was performed at 7T before and 48 hours, 1 week, and 1 month after CyberKnife radiation therapy. Tissue sodium concentration (TSC) was calculated and analyzed based on manually labeled regions of tumors. RESULTS Ultra-high-field sodium MR imaging clearly showed the intratumoral signal, which is significantly higher than that of normal tissue (t = 5.250, P <.001)., but the edema zone has some influence. The average TSC ratios of tumor to CSF in the 22 tumors, contralateral normal tissues, edema zones, frontal cortex, and frontal white matter were 0.66 (range, 0.23-1.5), 0.30 (range, 0.15-0.43), 0.58 (range, 0.25-1.21), 0.25 (range, 0.17-0.42), and 0.30 (range, 0.19-0.49), respectively. A total of 12 tumors in 8 patients were scanned at 48 hours, 1 week, and 1 month after treatment. The average TSC at 48 hours after treatment was 0.06 higher than that before treatment and began to decrease at 1 week. The TSC ratios of 10 continued to decline and 2 tumors increased at 1 month, respectively. Tumor volume decreased by 2.4%-99% after 3 months. CONCLUSIONS Changes in the TSC can be quantified by sodium MR imaging at 7T and used to detect radiobiologic alterations in intracranial tumors at early time points after CyberKnife radiation therapy.

Abstract
OBJECTIVE Prox1 is expressed in both lens epithelial cells and fiber cells and is essential for lens fiber cell elongation. This study aimed to explore the molecular mechanisms of how Prox1 mutations influence lens fiber cells development. MATERIALS AND METHODS Comparative transcriptomes analysis of Prox1 conditional knockout (cKO) lens and wild-type (WT) lens were performed using the data GSE69940 downloaded from the Gene Expression Omnibus database. Differentially expressed genes (DEGs) were determined by the R package "edgeR" of Trinity software. GO (Gene Ontology) enrichment analysis and KEGG (Kyoto Encyclopedia of Genes and Genomes databases) enrichment analysis were performed using the cluster Profiler R package. Then, the protein-protein interaction (PPI) network was predicted using Cytoscape, and the Module analysis of the PPI network was analyzed through the Cytoscape MCODE plugin. Moreover, MotifDb package in R was used to predict the transcription factors binding to Prox1 promoter regions. RESULTS In total, 2263 differentially expressed genes were identified between the two groups. GO and KEGG analysis showed that the down-regulated genes were enriched in camera-type eye term, nucleosome assembly, lens fiber cell differentiation, and cell modified and amino acid metabolism. The KEGG pathway of up-regulated genes was associated with lens development, including Hedgehog signaling pathway and MAPK signaling pathway. GO terms of up-regulated DEGs were mainly relevant to bone morphological development, muscle development, and sensory organ morphological development. Next, the PPI network of DEGs was constructed, and 4 modules were analyzed. Moreover, 30 transcription factors were predicted, which are likely to be downstream targets of Prox1 with potential roles in lens development in mice. CONCLUSIONS This study provides insights into the unique transcriptome profile of lens cells in Prox1 conditional knockout mice, which is a valuable resource for further study of mouse lens genomics.

Abstract
OBJECTIVE Cervical cancer is one of the gynecologic tumors in the world. The main aim of this study was to elucidate the functional role of MFI2 in cervical cancer and provide novel insight into biomarkers and therapeutic strategies for cervical cancer. PATIENTS AND METHODS The relative expression level of MFI2 was examined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Cell counting kit-8 (CCK-8) assay was involved to determine the ability of cell proliferation. Flow cytometric analysis was performed to detect cell apoptosis. Transwell assay and Matrigel assay were involved to determine cell migration and invasion. Expressions of protein kinase B (AKT), phosphorylated-AKT (p-AKT), B-cell lymphoma-2 (BCL2), and BCL2-Associated X (Bax) protein levels were detected in Western blotting. Transfected cells were used to perform tumor xenograft formation assay. RESULTS Our research validated that MFI2 was up-regulated in cervical cancer by qRT-PCR. Through CCK-8 assay, flow cytometric analysis, transwell assay, and Matrigel assay, we verified that MFI2 can promote cell proliferation, cell metastasis and inhibit cell apoptosis in cervical cancer. Subsequently, we used Western blotting assay to determine the alteration of protein expression of p-AKT, BCL2, and Bax. The results indicated that MFI2 may exert its function by regulating phosphatidylinositol 3-kinase (PI3K)/AKT signaling pathway. In tumor xenograft formation assay, up-regulated MFI2 accelerated tumor formation. CONCLUSIONS Current research elucidated that MFI2 promoted cell proliferation, cell metastasis and inhibited cell apoptosis in cervical cancer by regulating the PI3K/AKT signaling pathway. Our results may provide a novel insight into finding new therapeutic targets and biomarkers for cervical cancer.

Abstract
BACKGROUND We aimed to observe the effect of hypotensive brain death on the donor liver and understand its pathophysiological mechanism in improved pig model. METHODS The model was induced using the modified intracranial water sac inflation method in 16 Bama miniature pigs. Effects of hypotensive brain death on liver function and tissue morphology were evaluated via changes in liver function enzyme index, liver tissue alkaline phosphatase levels, hourly bile flow, and liver tissue pathology. Its pathophysiological mechanism was examined on the basis of changes in portal vein blood flow, hepatic artery blood flow, portal venous endotoxin level, and liver tissue cytokine levels. RESULTS After model establishment, portal vein blood flow, hepatic arterial blood flow, hourly bile flow, and alkaline phosphatase content in hepatic tissue significantly decreased, and serum aspartate aminotransferase, alkaline phosphatase, and lactate dehydrogenase levels significantly increased. Hematoxylin-eosin staining of liver tissue showed that after model establishment, hepatic tissue injury was gradually aggravated and hepatic cells were irreversibly damaged at 7 hours. Portal vein endotoxin levels significantly increased after brain death. Tumor necrosis factor α, interleukin 1, and endothelin 1 levels in liver tissues significantly increased at 3, 6, and 12 hours after brain death (P < .05), and hypoxia-inducible factor 1-α and nitric oxide levels significantly decreased (P < .05). CONCLUSIONS Hepatic injury was progressively aggravated under hypotensive brain death. The mechanism of donor liver injury under hypotensive brain death may involve low liver perfusion, release of intestinal endotoxin and inflammatory factors (eg, tumor necrosis factor α and interleukin 1), decreased hypoxia-inducible factor 1-α, and endothelin 1 and nitric oxide imbalance.

Abstract
Objective: To analyze the prevalence and risk factors of diabetic retinopathy (DR) in ophthalmic patients. Methods: A cross-sectional study was performed. Diabetic patients who were admitted to Department of Ophthalmology, Traditional Chinese Medicine Hospital of Muping between October 2012 and June 2013 were included. General information and medical history were obtained from each subject by questionaires. Laboratory and detailed ophthalmic examinations were performed during the study. DR was diagnosed and graded by mydriatic fundus photography. Prevalence of DR was calculated and logistic regression was used to analyze the relationship between DR and various factors. Results: A total of 676 diabetic patients were included, and 455 of them presented with DR at a morbidity rate of 67.31%. Among DR patients, the number of mild, moderate, severe non-proliferative diabetic retinopathy (NPDR) patients and proliferative diabetic retinopathy (PDR) patients were 211 (46.37%), 167 (36.70%), 57 (12.53%) and 20 (4.40%), respectively. There was no significant difference in the prevalence of DR among different age groups (χ(2)=6.527, P=0.089). However, there was a significant difference between different disease duration groups (χ(2)=39.401, P<0.001), as well as between insulin therapy group and non-insulin therapy group (χ(2)=7.378, P=0.007). The multivariate logistic regression analysis demonstrated the independent risk factors for DR occurrence were hemoglobin A1c (HbA1c) (OR=1.131, 95%CI: 1.022-1.252, P=0.011) and duration of diabetes (OR=1.077, 95%CI: 1.046-1.108, P<0.001). Conclusions: The prevalence of DR in ophthalmic patients was associated with duration of diabetes, HbA1c, obesity, smoke, nephropaty and insulin therapy. Increased HbA1c level and longer duration of diabetes were independent risk factors for DR in diabetic patients.

Abstract
This study aimed to explore the effects of active and latent Helicobacter pylori infection coupled with alcohol consumption on cytokine profiles and markers of oxidative balance in men seropositive for H. pylori CagA Ab.The 100 male subjects were divided into groups with active H. pylori infection and H. pylori CagA Ab coupled with chronic alcohol ingestion (group A, n = 38), latent H. pylori infection with H. pylori CagA Ab coupled with chronic alcohol ingestion (group B, n = 30), and latent H. pylori infection with H. pylori CagA Ab without chronic alcohol ingestion (group C, n = 32).No differences in serum levels of CRP, IL-10, ADP, E-selectin, MDA, or SOD were detected between the 3 groups or between any 2 groups (all P > .05). The serum IL-6 and TNF-α concentrations in groups A and B were significantly lower than those in group C (P = .004, P = .005, P = .009, and P = .023). However, there were no differences in serum IL-6 and TNF-α between group A and group B (all P > .05).In conclusion, active or latent H. pylori infection coupled with chronic alcohol ingestion may decrease certain cytokines, that is, IL-6 and TNF-α, in men with H. pylori CagA Ab seropositivity. However, there was no difference in the detected cytokine profile between active and latent H. pylori infection coupled with chronic alcohol ingestion, and no changes were detected in markers of oxidative balance in men with H. pylori CagA Ab.

Abstract
BACKGROUND AND OBJECTIVE Lens regeneration is an optimal strategy for cataract patients to regain visual acuity with accommodation. We recently designed a novel, minimally invasive capsulorhexis surgical method for cataract removal that achieved functional lens regeneration in human infants. However, small anterior capsulorhexis requires advanced surgical expertise. To examine whether the quality of the regenerated lens can be maintained with enlarged anterior capsulorhexis, we investigated the shape and transparency of the regenerated lenses with different anterior capsulorhexis diameters (ACDs). METHODS Thirty-six 4-week-old New Zealand albino rabbits were randomly divided into three groups which underwent lens extraction with different ACDs (Group A: 2.0±0.5 mm, Group B: 4.0±0.5 mm, Group C: 6.0±0.5 mm). The anterior capsule opening area (ACOA) was quantified, and the morphology, weight, and histological characteristics of the regenerated lenses were examined. RESULTS Lens regeneration was observed in all three groups. In Group A, the regenerated lenses were relatively complete and transparent. In Groups B and C, the regenerated lenses were doughnut-shaped and opaque. The speed of lens regeneration in Group A was significantly faster than that in Groups B and C. The ACOA in Group A healed quickly and completely approximately 2 weeks after surgery. However, in Groups B and C, ACOA did not heal completely until 12 weeks after surgery. Histological examination showed that in Group A, most of the lens epithelial cells differentiated into well-organized lens fibers. However, in Groups B and C, the regenerated lens fibers were disorganized. CONCLUSION Capsulorhexis size is a critical determinant of integrity and transparency in lens regeneration.

Abstract
This study assessed the prognostic value of BMAL1 and Ki-67 expression in patients with nasopharyngeal carcinoma. Level of BMAL1 mRNA was assessed in tissue specimens from 36 nasopharyngeal carcinomas and 20 nasopharyngeal chronic inflammations using quantitative reverse transcriptase-polymerase chain reaction. Expression of BMAL1 and Ki-67 proteins was analyzed immunohistochemically in 90 paired nasopharyngeal carcinoma and distant normal tissues. The Kaplan-Meier curves and the Log-rank test were used to calculate prognostic significance stratified by BMAL1 and Ki67 protein expression and the COX regression model was to analyze the multivariate prognosis. BMAL1 mRNA was significantly reduced in nasopharyngeal carcinoma (4.67 ± 0.27 versus 6.64 ± 0.51 in chronic inflammation tissues, p = 0.002). Level of BMAL1 mRNA was associated with tumor distant metastasis (3.37 ± 0.66 versus 5.04 ± 0.27 compared with non-metastasis, p = 0.011). Level of BMAL1 protein was also reduced in tumor tissues and BMAL1 expression was associated with better 1-, 3- and 5-year overall survival (OS) of cancer patients (92.6%, 69.2% and 62.3% versus 59.1%, 40.9% and 0% in patients with low BMAL1 expressed tumors; p = 0.000). BMAL1 expression and age were independent prognostic factors for OS (p = 0.032). Furthermore, Ki-67 expression was high in tumor versus normal tissues and associated with poor OS of cancer patients (p = 0.035). The Pearson correlation analysis showed that there was an inverse association between BMAL1 and Ki-67 protein expression (p = 0.021). This study demonstrated that lost BMAL1 and Ki-67 overexpression were associated with poor OS of nasopharyngeal carcinoma patients.

Abstract
The rat orthotopic liver transplantation model with extremely short anhepatic phase was established to study its protective effect on the recipients and graft. One hundred fifty adult male Wistar rats were randomly divided into three groups: group A (n = 30), using magnetic rings for the suprahepatic vena cava reconstruction; group B (n = 30), using 7/0 Prolene sutures for suprahepatic vena cava running anastomosis as control; and a sham-operated group (n = 30) as a blank control group. The changes in liver enzyme, serum creatinine, endotoxin, and cytokine levels and histopathology were recorded. The serum creatinine, potassium, alanine transaminase, and alkaline phosphatase levels at different points in time in group A were lower than those in group B (P < .05). The level of portal vein blood endotoxin in group A was significantly lower than that in group B at each point (P < .01). At the same time, all the cytokines in group B were higher than those in group A, and the two groups were higher than those in the sham operation group. The mean levels of tumor necrosis factor-α (TNF-α), interferon-γ, (IFN-γ), and interleukin-1ß (IL-1ß) at 3 hours were higher than at 6 hours in group A. IL-10 and tissue inhibitor of metalloproteinase-1 (TIMP-1) were all higher at 3 hours in groups A and B. Levels of monocyte chemotactic protein-1, L-selectin, and TIMP-1 in group A and IL-10, monocyte chemotactic protein-1, L-selectin, and TIMP-1 in group B were higher in blood than in the liver. Levels of TNF-α, IFN-γ, IL-1, IL-10, and intracellular adhesion molecule-1 in group A and TNF-α, IFN-γ IL-1ß, and intracellular adhesion molecule-1 in group B were higher in the liver than in blood. We conclude that the extremely short anhepatic phase has protective effects on recipients and grafts in rat liver transplantation because it is related to alleviating ischemia-reperfusion injury and reducing the endotoxin release.

Abstract
Objective: To investigate the inhibitory effect of migration-inducing gene-7(Mig-7)interfered with retrovirus-mediated RNA(shRNA)combined with recombinant human endostatin(ES)on the growth and metastasis of subcutaneous xenograft of human hepatoma cells in nude mice. Methods: Two Mig-7-mRNA oligonucleotide sequences(Mig-7-shRNA-1 and Mig-7-shRNA-2)and one sequence as a negative control(Mig-7-shRNA-N)were designed. The specific Mig-7-shRNA recombinant retrovirus expression vector plasmid was constructed and used for the transfection of human hepatoma MHCC-97H cells with high expression of Mig-7. The subcutaneous xenograft tumor model of human hepatocellular carcinoma(HCC)in nude mice was established, and according to the condition of transfection and administration, the nude mice were divided into pSIREN-M1 group, pSIREN-MN group, ES group, and pSIREN-M1+ES group. The xenograft tumor volume, mass, and metastasis were compared between groups. Immunohistochemistry was used to observe the formation of vasculogenic mimicry(VM)in xenograft tumor and the difference in tumor microvascular density(MVD), and Western blot was used to measure the expression of Mig-7 and vascular endothelial growth factor(VEGF)in each group. A one-way analysis of variance was used for comparison between groups, and the Fisher's exact test was used for comparison of continuous data between groups. Results: Compared with the pSIREN-MN group, the pSIREN-M1 group had significantly lower xenograft tumor volume, mass, and metastasis rate, Mig-7 expression, and formation of VM(P < 0.05), as well as significantly higher VEGF expression and MVD(P < 0.05). Compared with the pSIREN-MN group, the ES group had significantly lower xenograft tumor volume, mass, and metastasis rate, VEGF expression, and MVD(P < 0.05), as well as significantly higher Mig-7 expression and formation of VM(P < 0.05). Compared with the pSIREN-M1 group and the ES group, the pSIREN-M1+ES group had significantly lower xenograft tumor volume, mass, and metastasis rate, Mig-7 expression, formation of VM, VEGF expression, and MVD(P < 0.05). Conclusion: Mig-7-shRNA recombinant retrovirus combined with ES has a better inhibitory effect on the growth and metastasis of HCC xenograft tumor than Mig-7-shRNA recombinant retrovirus or ES alone. The anti-tumor angiogenesis therapy alone, which targets vascular endothelial cells in vivo, has a limited effect, since it may promote the formation of VM.

Abstract
Previous studies have reported a relationship between alcohol consumption and carotid intima-media thickness (CIMT). However, the exact associations between different severities of CIMT and dyslipidemia, dyslipoproteinemia, inflammatory immune markers, and oxidative markers associated with chronic alcohol consumption remain unknown. The aim of this study was to explore whether there are associations between different severities of CIMT and dyslipidemia, dyslipoproteinemia, inflammatory immune markers, and oxidative markers associated with chronic alcohol consumption. We enrolled 173 males with chronic alcohol consumption and categorized them into 2 groups: 104 chronic alcohol consumers with normal CIMT (group A) and 69 chronic alcohol consumers with increased CIMT (group B). Nonparametric statistics showed that age, body mass index (BMI), and serum TC, TG, Apo A1, and ApoB levels were significantly higher in group B than in group A (P = 0.002, 0.019, 0.021, 0.023, 0.001, and 0.001, respectively). Additionally, tumor necrosis factor alpha (TNFα) and HSP70 serum levels were significantly lower in group B than in group A (P = 0.023 and 0.017, respectively). A binary logistic regression analysis showed that age (OR: 1.077, 95% CI: 1.024-1.13, P = 0.004), ApoB (OR: 6.828, 95% CI: 1.506-30.956, P = 0.013), and TNF-α (OR: 0.999, 95% CI: 0.998-1.00) were independent risk factors associated with CIMT. The present study demonstrated that age, ApoB, and TNFα are independent risk factors associated with CIMT. Thus, older subjects with increased serum ApoB levels are more likely to present with increased CIMT, suggesting that age and ApoB promote such thickening and that TNFα downregulation might play a protective role against the progression of subclinical atherosclerosis in subjects with chronic alcohol consumption.
