CONCLUSIONS: This article offers a comprehensive review of the present status of ROP research, along with insights into emerging concepts and potential international collaborations in this field.

A Neural Network-based Method for Predicting Dose to Organs at Risk in Intensity-modulated Radiotherapy for Nasopharyngeal Carcinoma.

OBJECTIVE: A neural network method was used to establish a dose prediction model for organs at risk (OARs) during intensity-modulated radiotherapy (IMRT) for nasopharyngeal carcinoma (NPC). MATERIALS AND METHODS: In total, 103 patients with NPC were randomly selected for IMRT. Suborgans were automatically generated for OARs using ring structures based on distance to the target using a MATLAB program and the corresponding volume of each suborgan was determined. The correlation between the volume of each suborgan and the dose to each OAR was analysed and neural network prediction models of the OAR dose were established using the MATLAB Neural Net Fitting application. The R-value and mean square error in the regression analysis were used to evaluate the prediction model. RESULTS: The OAR dose was related to the volume of the corresponding sub-OAR. The average R-values for the normalised mean dose (Dnmean) to parallel organs and serial organs and the normalised maximum dose (Dn0) to serial organs in the training set were 0.880, 0.927 and 0.905, respectively. The mean square error for each OAR in the prediction model was low (ranging from 1.72 × 10-4 to 7.06 × 10-3). CONCLUSION: The neural network-based model for predicting OAR dose during IMRT for NPC is simple, reliable and worth further investigation and application.

Effect of resistance exercise on peripheral inflammatory biomarkers in healthy adults: a meta-analysis of randomized controlled trials.

OBJECTIVE: This study aimed to evaluate the effect of resistance exercise on peripheral inflammatory biomarkers in healthy adults. MATERIALS AND METHODS: Four databases, including PubMed, Web of Science, Cochrane Library, and SPORTDiscus, were searched from inception until April 1st, 2022. A meta-analysis was conducted using a random-effects model, followed by sensitivity analysis, subgroup analysis, meta-regression analysis, and publication bias analysis. RESULTS: 15 randomized controlled trials were included in the meta-analysis. The pooled results showed that resistance exercise significantly decreased TNF-α levels (SMD = -0.81, 95% CI: -1.42 to -0.20, p = 0.009) but did not affect IL-6 and CRP levels. Individuals with BMI 18.5-24.9 exhibited significantly decreased IL-6 levels, while moderate strength resistance exercise could significantly decrease TNF-α levels. Finally, age might be a confounding factor influencing the effect of resistance exercise on IL-6. CONCLUSIONS: Resistance exercise could reduce TNF-α levels in healthy adults, and resistance exercise with moderate intensity could reduce TNF-α levels more effectively.

The clinical characteristic of alcohol-hyperlipidemia etiologically complex type of acute pancreatitis.

OBJECTIVE: The aim of our study was to elucidate the clinical characteristics of alcoholic-hyperlipidemic etiologically complex acute pancreatitis. PATIENTS AND METHODS: We reviewed complete data from 233 patients with acute pancreatitis treated in our hospital during the period January 2017-January 2022. They were divided into three groups according to etiology: alcoholic acute pancreatitis (AAP), hyperlipidemic acute pancreatitis (HLAP), and alcoholic-hyperlipidemic acute pancreatitis (AHAP). General clinical data, co-morbidities, laboratory results, imaging data, and disease severity were analyzed and compared between groups. RESULTS: The proportion of male individuals in the AHAP group was significantly higher than that in the HLAP group (p<0.001). Age of onset was lower and the number of cases with antibiotic use was higher in the AHAP group than in the AAP group (p<0.05). Additionally, the average alcohol intake each time and weekly alcohol intake were also higher in the AHAP group than in the AAP group (p<0.05). Comparison of disease severity (moderate and severe acute pancreatitis, severe acute pancreatitis, and modified computed tomography severity index score) revealed the disease condition to be more severe in the AHAP group than in the AAP and HLAP groups (p<0.05). Accordingly, patients in the AHAP group had longer hospital stays than those in the other two groups (p<0.05). There were no significant differences in alcohol consumption, severity, or length of hospital stay in the AHAP group (p>0.05). CONCLUSIONS: The clinical characteristics of patients in the AHAP, AAP and HLAP groups were different, and the patients in the AHAP group were more likely to have a moderate to severe disease course, with longer hospital stay. As a new AP classification concept, AHAP would offer high significance for diagnosis, treatment, and prognosis.

Effects of aerobic exercise on inflammatory factors in healthy adults: a meta-analysis.

OBJECTIVE: With this meta-analysis we aimed at systematically evaluating the intervention effects of aerobic exercise on inflammatory factors in healthy adults and identifying an optimal aerobic exercise program with anti-inflammatory effects. MATERIALS AND METHODS: Four databases, including PubMed, Web of Science, Cochrane Library and SPORTDiscus, were searched from inception until April 30, 2021. Stata version 11.0 was used for data analysis. RESULTS: A total of 15 studies with 1160 participants were included. The pooled estimates showed that aerobic exercise could significantly reduce TNFα levels (SMD=-0.30, 95% CI: -0.58 - -0.03, p=0.032), while the levels of IL-6 (SMD=-0.14, 95% CI: -0.32-0.03, p=0.109) and CRP (SMD=-0.09, 95% CI: -0.34-0.16, p=0.484) were not significantly affected. CONCLUSIONS: Aerobic exercise exerts a positive effect by preventing inflammation-related diseases.

Inhibition of A2AR gene methylation alleviates white matter lesions in chronic cerebral hypoperfusion rats.

OBJECTIVE: Chronic cerebral hypoperfusion (CCH) can cause ischemic cerebral white matter lesions (IWML). The aim of this study was to explore the roles of A2A receptors (A2AR) in IWML and the effect of methylation in A2AR gene. MATERIALS AND METHODS: SD rat model of CCH was constructed by bilateral common carotid artery occlusion (BCCAO) method. The rats were then treated with DNA methyltransferase (DNMT) inhibitor (decitabine), agonist (CGS21680) and A2AR inhibitor (SCH58261). Morris water maze and Kluver-Barrera staining were used to assess spatial learning and reference memory after IWML, respectively. Gene transcription and protein expression were measured by qRT-PCR, Enzyme-linked immunosorbent assay (ELISA) and Western blotting, respectively. The concentration of malondialdehyde (MDA), activity of superoxide dismutase (SOD) and DNMT were detected by assay kit. Methylation of A2AR gene promoter region was detected by bisulfite sequencing PCR (BSP). RESULTS: We found that the down-regulated expression of A2AR in corpus callosum under CCH was associated with IWML and cognitive impairment. We further showed that A2AR agonist can reduce the IWML under CCH, and A2AR inhibitor can aggravate the IWML under CCH. We also found that the expression level of DNMTs in corpus callosum and the methylation level in the promoter region of A2AR gene were increased under CCH. DNMT inhibitors could protect white matter by inhibiting the methylation of A2AR promoter and rescue the downregulation of A2AR under CCH. CONCLUSIONS: Our results demonstrate that the downregulation of A2AR mediates IWML in CCH, and A2AR downregulation is related to the increased methylation of A2AR gene promoter. DNMT inhibitors play a protective role in IWML.

A clinical nomogram for predicting renal calculus of university teachers.

OBJECTIVE: To establish a prediction model of renal calculus for university teachers to help them prevent renal calculus scientifically. This study involves a specific group of university teachers. We collected the physical examination index of 1043 university teachers in the Hubei University of Chinese Medicine in 2018 to build the model. We also used the physical examination data of 968 teachers in 2019 to verify the model. MATERIALS AND METHODS: We used Lasso regression to screen the factors and logistic regression analysis to establish the model. RESULTS: The models of this study included sex, age, DBP, TC, HDL. C, CEA, UA, ALT, GGT, HB, pH, RBC, RDW, and CLYMPH. Among these, sex, TC, ALT, HB, and LYMPH present high risks in the model. The result is of great significance related to the research of university teachers suffering from renal calculus. The C-index is 0.715, and the AUC is 0.7064. CONCLUSIONS: Based on the results of this study, we suggest that physical examination indicators can predict the risk of renal calculus and the individual probability of prevalence in specific groups. According to the risk of each physical examination index, it is possible to effectively prevent the occurrence of renal calculus in certain high-risk groups through lifestyle changes.

The clinical characteristic of biliary-hyperlipidemic etiologically complex type of acute pancreatitis: a retrospective study from a tertiary center in China.

OBJECTIVE: Biliary and hyperlipidemic acute pancreatitis (AP) has become the second most common AP in China. Currently, AP is exclusively diagnosed as biliary or hyperlipidemic AP. However, as suggested by some reports, biliary and hyperlipidemic AP might coexist in a single patient. Moreover, acute lipotoxicity was shown to regulate the severity of biliary AP in the mouse model. Thus, whether these two etiologies coexist in AP patients and potentially worsen the clinical course remains unclear. To elucidate the clinical feature of a new complex type of acute pancreatitis with both biliary and hyperlipidemic etiologies. PATIENTS AND METHODS: This retrospective study included AP patients who were admitted into our department within 7 days after the onset of the disease. 267 AP patients were enrolled in this study and were classified as BAP (biliary acute pancreatitis, n=153), HLAP (hyperlipidemic acute pancreatitis, n=65) and BHAP (biliary-hyperlipidemic acute pancreatitis, n=49). All the enrolled patients met the classification criteria of biliary etiology, hyperlipidemic etiology, and both etiologies, respectively. BHAP was compared with BAP and HLAP in terms of general information, inflammatory biomarkers, organ dysfunction, disease severity and clinical outcomes. RESULTS: BHAP (41 vs. 53) patients were younger than BAP patients. Serum procalcitonin of BHAP patients was higher than BAP and HLAP patients. Serum CRP of BHAP patients was higher than BAP patients. BHAP patients had the highest diagnosis rate of severe acute pancreatitis (SAP) (46.9% vs. 17.6% or 21.5%) compared to BAP and HLAP. Prevalences of persistent respiratory, acute renal, and circulatory failure were highest in BHAP patients (44.9%, 28.6%, 12.2%, respectively). Requirements for mechanical ventilation, renal replacement therapy and vasoactive agents were also highest in BHAP patients (36.7%, 34.7%, 12.2%, respectively). Hospital stay was longer in BHAP patients (33 days) compared with BAP patients (24 days). CONCLUSIONS: Patients with both biliary and hyperlipidemic etiologies suffer from more severe clinical course of the disease and have worse prognosis than single-etiology BAP or HLAP patients in the early stage of AP (within 7 days). It should be recognized as a new etiological type named biliary-hyperlipidemic acute pancreatitis (BHAP).

Association of sepsis with risk for osteoporosis: a population-based cohort study.

We conducted a large, retrospective cohort study using data from Taiwan's National Health Insurance Research Database to evaluate whether the risk of developing osteoporosis is associated with sepsis. Our study found that adults younger than 65 years with sepsis had a significantly increased risk of developing osteoporosis. INTRODUCTION: There have been limited studies regarding the osteoporosis risk associated with sepsis. Our purpose is to evaluate whether the risk of developing osteoporosis is associated with sepsis. METHODS: We conducted a large, retrospective cohort study using data from Taiwan's National Health Insurance Research Database. From the insurance claims data, a total of 13,178 patients diagnosed with sepsis from 2000 to 2012 were included in the sepsis cohort, and a propensity score-matched cohort included 13,178 individuals without sepsis. To calculate the incidence of osteoporosis, both groups were followed until 2013. Cox regression analysis was performed to obtain the hazard ratios (HRs) to assess the risk of developing osteoporosis. The Kaplan-Meier method was used to estimate the cumulative incidence of osteoporosis. RESULTS: The overall incidences of osteoporosis (per 1,000 person-years) in the sepsis and non-sepsis groups were 10.2 and 10.7, respectively. The risk of osteoporosis significantly increased in the presence of sepsis (adjusted HR = 1.17, 95% confidence interval (CI) = 1.04-1.31). The risk of osteoporosis in the sepsis group was significantly higher than that in the non-sepsis group for young patients aged 20-49 years and patients aged 50-64 years (adjusted HR = 1.93, 95% CI = 1.08-3.44; adjusted HR = 2.01, 95% CI = 1.52-2.65, respectively). The Kaplan-Meier curves of cumulative probability also showed a significantly increased risk of osteoporosis in patients aged 20-49 years and aged 50-64 years with sepsis compared with non-sepsis (P = 0.025; P < 0.001, respectively). CONCLUSION: Adults younger than 65 years with sepsis had a significantly increased risk of developing osteoporosis.

MicroRNA-130b inhibits cerebral ischemia/reperfusion induced cell apoptosis via regulation of IRF1.

OBJECTIVE: Cerebral ischemia/reperfusion (CIR) frequently causes serious disabilities and correlates with certain neurological processes. Some studies have shown that microRNAs (miRNAs) exert a neuroprotective effect by modulating the inflammatory process in CIR. However, the biofunction and the mechanism of miR-130b in CIR need to be fully elucidated. MATERIALS AND METHODS: An oxygen-glucose deprivation/reperfusion (OGD/R) model was constructed using SH-SY5Y cell line to analyze the function of miR-130b in CIR. Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was used to examine the expression levels of miR-130b and IRF1. Western blot was performed to detect the protein levels of IRF1, Bax, and Bcl-2. Cell viability was determined using MTT (3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assays. Dual-Luciferase reporter assay was conducted to confirm the target gene of miR-130b. RESULTS: In this study, we found that miR-130b level was prominently decreased after treatment with OGD/R. Through gain and loss assays, we concluded that miR-130b restoration promoted cell proliferation and inhibited cell apoptosis in OGD/R-treated cells. Moreover, we also identified IRF1 as an important target of miR-130b. Additionally, IRF1 knockdown remarkably abrogated the protection mediated by miR-130b against the injuries in OGD/R-treated cells. CONCLUSIONS: Taken together, our results suggested that miR-130b facilitated cell viability and suppressed cell apoptosis of CIR via negatively regulating of IRF1.

Risk factors for inadvertent arterial puncture during subclavian vein catheterization.

OBJECTIVE: Central vein catheterizations facilitate the establishment of reliable venous pathways in emergent medical situations. The subclavian is an important vein for central venous catheterizations. But, inadvertent arterial punctures during subclavian vein catheterizations are more dangerous than those during jugular or femoral vein catheterizations, because of the lack of a reliable compression site. We aimed to identify risk factors for the occurrence of inadvertent arterial puncture during subclavian vein catheterizations in crowded emergency rooms. PATIENTS AND METHODS: We evaluated 190 patients undergoing bedside subclavian vein catheterizations in our emergency room, from which 62 patients experienced inadvertent arterial punctures. We evaluated possible risk factors from basic physical or laboratory tests that can easily be obtained in the ER, and performed Chi-square test, Kruskal-Wallis ANOVA, non-conditional logistic regression analysis, and receiver-operating characteristic curves to determine the cut-off values of the identified risk factors. RESULTS: We identified age, BMI, and serum pre-albumin level as significant risk factors for inadvertent arterial puncture during subclavian vein catheterization (p<0.05) through regression analyses (odds ratios of 1.043, 0.719 and 0.989; and receiver-operating characteristic curves with AUCs of 0.741, 0.818, and 0.717, respectively). The cut-off values for age, BMI and serum pre-albumin level were 66.5 years old, 21.12 and 109.5 mg/L, respectively. CONCLUSIONS: We found that patients with poor nutritional status (BMI <21.12 and serum pre-albumin <109.5 mg/L) or older than 69.5 years tended to experience more accidental arterial punctures during subclavian vein catheterizations, probably due to atrophy or diminished peri-vascular support tissues in patients with poor nutritional statuses that make it difficult to obtain adequate chest extensions.

MED27 promotes malignant behavior of cells by affecting Sp1 in breast cancer.

OBJECTIVE: The aim of this study was to investigate the expression of mediator complex subunit 27 (MED27) in breast cancer (BC) and explore its effects on the proliferation and apoptosis of BC cells. PATIENTS AND METHODS: The expression of MED27 in 60 BC tissues and para-cancer tissues was detected. Based on the significantly high expression level of MED27 in tumors, the tumor samples were divided into high-expression group and low-expression group according to the median standard, with 30 samples in each group. Then, the association between MED27 expression and clinicopathological features of patients was analyzed. The correlation between MED27 expression and survival time of patients was estimated using the Kaplan-Meier method. Next, the expression level of MED27 in cells was also measured using qRT-PCR assay. In vitro study, si-MED27 was designed to interfere with the expression of MED27 in MDA-MB-231 cells. To further explore the mechanism of MED27 in BC, the expression level of SP1 in cells was examined after different treatments. RESULTS: In quantitative reverse transcription-polymerase chain reaction (qRT-PCR) assay, MED27 was found to be highly expressed in both BC tissues and cells. Then, the relationship between MED27 expression and clinical pathological data was statistically analyzed, and it was found that MED27 expression was correlated with tumor size and grade. In the 60-month follow-up and Kaplan-Meier analysis, patients with high expression of MED27 had a poor prognosis. In in vitro study, MED27 expression in cells was down-regulated by transfection with si-MED27. Western blot (WB) analysis suggested that si-MED27 could effectively reduce the protein expression level of MED27 in cells, and the specificity protein 1 (Sp1) expression was also limited. In CCK-8, clone formation and flow cytometry experiments, the proliferation of cells with low MED27/Sp1 expression was suppressed, while cell apoptosis was promoted. CONCLUSIONS: MED27 acted as an oncogene in BC. By affecting Sp1, MED27 could be a new therapeutic target for the treatment of BC.

MicroRNA-577 inhibits cardiomyocyte apoptosis induced by myocardial infarction via targeting PARP1.

OBJECTIVE: The aim of this study was to investigate whether microRNA-577 could inhibit myocardial infarction (MI)-induced cardiomyocyte apoptosis by regulating poly ADP-ribose polymerase 1 (PARP1). MATERIALS AND METHODS: MI model was successfully established in mice by ligation of the left anterior descending coronary artery (LAD). The expression levels of microRNA-577 and PARP1 in myocardial tissues of mice were examined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). MI model in cells was established by hypoxia pre-treatment in primary cardiomyocytes and MCM cells. Subsequently, the expression levels of microRNA-577 and PARP1 in hypoxia preconditioning cardiomyocytes were determined as well. Meanwhile, Caspase3 activity in cardiomyocytes overexpressing microRNA-577 or PARP1 was detected using a relative commercial kit. Furthermore, the binding relationship between microRNA-577 and PARP1 was examined by Dual-Luciferase reporter gene assay. RESULTS: Infarct size/risk region and risk region/LV in MI group were (62.1±2.2)% and (57.6±1.9)%, respectively. Both of the above two indexes in the MI group were significantly higher than those of the control group. The serum level of LDH in MI mice increased by 2.8-fold when compared with controls. Meanwhile, the expressions of microRNA-577 and PARP1 in myocardial tissues of MI mice were markedly down-regulated in a time-dependent manner. Compared with normoxia preconditioning cardiomyocytes, microRNA-577 expression in hypoxia preconditioning MCM cells and primary cardiomyocytes was remarkably decreased. Dual-Luciferase reporter gene assay confirmed that microRNA-577 could bind to PARP1. After transfection of microRNA-577 mimics, the expression of PARP1 was significantly down-regulated. Moreover, microRNA-577 over-expression inhibited caspase3 expression in hypoxia preconditioning cells, which could be reversed by PARP1 up-regulation. Similarly, microRNA-577 over-expression markedly decreased infarct size, risk region and serum level of LDH in MI mice, which could be reversed by PAPR1 over-expression. CONCLUSIONS: MicroRNA-577 inhibits MI-induced cardiomyocyte apoptosis by degrading PARP1.

MicroRNA-579-3p promotes the progression of osteoporosis by inhibiting osteogenic differentiation of mesenchymal stem cells through regulating Sirt1.

OBJECTIVE: To explore whether microRNA-579-3P was involved in the development of osteoporosis, and to investigate the possible molecular mechanisms. PATIENTS AND METHODS: The messenger RNA (mRNA) expression levels of microRNA-579-3P, alkaline phosphatase (ALP), runt-related transcription factor 2 (RUNX2) and bone sialoprotein (BSP) in serum samples of osteoporosis patients and normal controls were detected by quantitative Real-time polymerase chain reaction (qRT-PCR), respectively. Meanwhile, the expressions of the above genes during osteogenic differentiation of human bone marrow mesenchymal stem cells (hMSCs) were examined as well. To investigate the effect of microRNA-579-3P on osteogenesis, microRNA-579-3P was overexpressed and knocked down in hMSCs. Subsequently, the mRNA and protein expression levels of osteogenesis-related genes, such as ALP, RUNX2 and BSP, were detected by qRT-PCR and Western blot, respectively. In addition, ALP activity and mineralization forming ability were evaluated by ALP staining and alizarin red staining. Bioinformatics predicted that Sirt1 was the target gene of microRNA-579-3P. Subsequent luciferase reporter gene assay was performed to verify the binding relationship of microRNA-579-3P to Sirt1. Meanwhile, qRT-PCR and Western blot were used to detect the changes in the mRNA and protein expression levels of Sirt1, respectively. After overexpression of microRNA-579-3P and Sirt1, qRT-PCR, Western blot, ALP staining and alizarin red staining assays were performed to detect the osteogenic differentiation of hMSCs. RESULTS: The expression of microRNA-579-3P in serum of patients with osteoporosis was significantly higher than that of normal controls. Meanwhile, the expression of microRNA-579-3P decreased gradually during osteogenic differentiation of hMSCs. Overexpression of microRNA-579-3P significantly reduced the expressions of osteogenic related genes, including ALP, RUNX2 and BSP. Besides, ALP activity and mineralized nodule formation ability decreased obviously as well. Luciferase reporter gene assay showed that microRNA-579-3P could bind to Sirt1. After overexpression of microRNA-579-3P, the mRNA and protein expression levels of Sirt1 were significantly reduced, which were reversed after silence of microRNA-579-3P. Simultaneous overexpression of microRNA-579-3P and Sirt1 could reverse the inhibition of osteogenic differentiation of hMSCs caused by overexpression of microRNA-579-3P alone. CONCLUSIONS: MicroRNA-579-3P could inhibit osteogenic differentiation of hMSCs by regulating Sirt1, thereby promoting the development of osteoporosis.

MiRNA-8073 targets ZnT1 to inhibit malignant progression of ovarian cancer.

OBJECTIVE: The purpose of this study was to investigate the effect of microRNA-8073 on the malignant progression of ovarian cancer (OC) and whether the underlying mechanism is through the regulation of ZnT1 expression. PATIENTS AND METHODS: Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was used to detect the expression of microRNA-8073 in 50 tumor tissues and adjacent tissues of OC patients, and the relationship between microRNA-8073 expression and clinical indicators of OC was analyzed. Negative control group (NC) and microRNA-8073 overexpression group (microRNA-8073 mimics) were set in OC cell lines, and the transfection efficiency was further verified by qRT-PCR. In OC cell lines including SKOV3 and OVCAR3, the effects of microRNA-8073 on cell proliferation and apoptosis were analyzed by cell counting kit-8 (CCK-8), cell clone formation assay, and flow cytometry. Finally, the regulatory mechanism of microRNA-8073 on the downstream gene ZnT1 was explored by a recovery experiment. RESULTS: QRT-PCR results revealed that microRNA-8073 expression in cancer tissue specimens of OC patients was significantly lower than that in corresponding normal tissues, and the difference was statistically significant. Compared with patients with high expression of microRNA-8073, NC group had low expression of microRNA-8073 and had a higher pathological stage and lower overall survival rate. In the OC cell lines including SKOV3 and OVCAR3, compared with the NC group, the cell proliferation ability of the microRNA-8073 mimics group was significantly decreased, while the apoptotic ability was significantly increased. Also, ZnT1 had high expression in OC cell lines and tissues and was confirmed negatively correlated with microRNA-8073 level. Meanwhile, the recovery experiment revealed that overexpression of ZnT1 can counteract the effect of microRNA-8073 mimics on OC cell proliferation and apoptosis so as to affect the malignant progression of OC. CONCLUSIONS: We demonstrated that microRNA-8073 was significantly associated with the pathological stage and poor prognosis of OC. In addition, microRNA-8073 might inhibit malignant progression of OC by regulating ZnT1 expression.
