ABSTRACT Purpose: To investigate the role of cyanidin-3-O-glucoside (C3G) in renal ischemia/reperfusion (I/R) injury and the potential mechanisms. Methods: Mouse models were established by clamping the left renal vessels, and in vitro cellular models were established by hypoxic reoxygenation. Results: Renal dysfunction and tissue structural damage were significantly higher in the I/R group. After treatment with different concentrations of C3G, the levels of renal dysfunction and tissue structural damage decreased at different levels. And its protective effect was most pronounced at 200 mg/kg. The use of C3G reduced apoptosis as well as the expression of endoplasmic reticulum stress (ERS)-related proteins. Hypoxia/reoxygenation (H/R)-induced apoptosis and ERS are dependent on oxidative stress in vitro. In addition, both AG490 and C3G inhibited the activation of JAK/STAT pathway and attenuated oxidative stress, ischemia-induced apoptosis and ERS. Conclusions: The results demonstrated that C3G blocked renal apoptosis and ERS protein expression by preventing reactive oxygen species (ROS) production after I/R via the JAK/STAT pathway, suggesting that C3G may be a potential therapeutic agent for renal I/R injury.

Abstract African swine fever (ASF) is an important viral disease of swine caused by the African swine fever virus (ASFV), which threatens swine production profoundly. To better understand the gene expression changes when pig infected with ASFV, RNA sequencing was performed to characterize differentially expressed genes (DEGs) of six tissues from Kenya domestic pigs and Landrace × Yorkshire (L/Y) pigs infected with ASFV Kenya1033 in vivo. As results, a total of 209, 522, 34, 505, 634 and 138 DEGs (q-value < 0.05 and |Log2foldchange| values >2) were detected in the kidney, liver, mesenteric lymph node, peripheral blood mononuclear cell, submandibular lymph node and spleen, respectively. The expression profiles of DEGs shared in the multiple tissues illustrated variation in regulation function in the different tissues. Functional annotation analysis and interaction of proteins encoded by DEGs revealed that genes including IFIT1, IFITM1, MX1, OASL, ISG15, SAMHD1, IFINA1, S100A12 and S100A8 enriched in the immune and antivirus pathways were significantly changed when the hosts were infected with ASFV. The genes mentioned could play crucial roles in the process of the reaction to non-lethal ASF infection, which may will help to improve the ASF tolerance in the pig population through molecular breeding strategies.

Neuroblastoma is one of the most common tumors in children. Cases where an isolated soft-tissue metastasis mass is the initial symptom are rare, with only four such cases reported to date. We describe the imaging findings of ten cases of neuroblastoma patients in our hospital with superficial soft tissue mass (SSTM) as the primary symptom. The main ultrasound finding of SSTM was hypoechoic masses or scattered speck-like hyperechoic masses. However, when this type of SSTM is caused by soft tissue metastasis, the location is often atypical, and ultrasound findings are difficult to distinguish from other benign diseases. Therefore, this research should remind clinicians to recognize atypical presentations of this common childhood malignant tumor. Radiologists should also consider the possibility of neuroblastoma when finding this type of SSTM with atypical ultrasound features. children softtissue rare date (SSTM specklike speck like However diseases Therefore tumor features

Abstract In this study, we aimed to compare clinical efficacy of laparoscopic surgery and open surgery for colorectal cancer in the Huaihe River Basin in China. A total of 92 patients with colorectal cancer were selected as subjects. Patients were divided into control group (open surgery, n = 27 cases) and test group (laparoscopic surgery, n = 28 cases). Our results showed that the duration of operation (122.54 ± 14.85) min and length of incision (4.51 ± 1.065) cm were shorter in the experimental group than those in the control group. The intraoperative blood loss of the experimental group was (161.12 ± 10.694) ml, which was less than that of the control group (218.53 ± 15.369) ml (P < 0.05). Patients in the experimental group have higher Five-year survival rate and lower incidence of postoperative complications than those in the control group (all P < 0.05). In conclusion, in the treatment of colorectal cancer, laparoscopic surgery has a better clinical effect than open surgery, which is worthy of clinical application.

Abstract The authentication of fresh apple juice (FAJ) is a significant issue. However, the main characteristics of FAJ, diluted apple juice (DAJ) with added concentrated apple juice (DAJ+CAJ), and DAJ with added sucrose (DAJ+s) are not different when using classical chemical analyses in juice authentication. In this study, isotope ratio mass spectrometry (IRMS) was used to determine the δD, δ18O, and δ13C in adulterated apple juice for juice authentication. The δD and δ18O values were decreased in adulterated juice. A linear correlation was found between δD and δ18O in apple juices with different amount of adulteration. Therefore, this linear relationship can be used to determine the amount of adulteration that took place. The δ13C value and the content of each component in real apple juice are within specific ranges. The adulteration can be recognized once the δ13C value and the content of each component in the apple juice are out of these ranges. The implementation of this method would help maintain the juice market’s stability and protect consumers’ interests.

Abstract There are many restrictions on topical medications for the oral cavity. Various factors affect the topical application of drugs in the oral cavity, an open and complex environment. The complex physical and chemical environment of the oral cavity, such as saliva and food, will influence the effect of free drugs. Therefore, drug delivery systems have served as supporting structures or as carriers loading active ingredients, such as antimicrobial agents and growth factors (GFs), to promote antibacterial properties, tissue regeneration, and engineering for drug diffusion. These drug delivery systems are considered in the prevention and treatment of dental caries, periodontal disease, periapical disease, the delivery of anesthetic drugs, etc. These carrier materials are designed in different ways for clinical application, including nanoparticles, hydrogels, nanofibers, films, and scaffolds. This review aimed to summarize the advantages and disadvantages of different carrier materials. We discuss synthesis methods and their application scope to provide new perspectives for the development and preparation of more favorable and effective local oral drug delivery systems.

Abstract A novel sugarcane juice beverage was successfully produced by liquid fermentation of G. lucidum and homogenate process with selecting the day 10 fermentation broth as the raw materials. The beverage was evaluated for its sensory, nutritional and antioxidant activities. The results showed that the beverage by the G.lucidum fermentation was rich in polysaccharides, triterpenes, proteins, and flavonoids, which were all significantly higher than sugarcane juice, especially polysaccharides and triterpenoids. And the beverage could retain the sensory quality of sugarcane juice and could therefore be favored by the consumers. The in vitro antioxidant activity showed that the beverage had high scavenging and reducing abilities. DPPH and ABTS•+ radical scavenging rate of 1 mL fermented beverage were similar to 0.04 mg/mL VC, while the hydroxyl radical scavenging rate and reducing power of 1 mL of fermented beverage were similar to 1.68 mg/mL and 0.19 mg/mL VC, respectively. Taken together, the sugarcane juice fermented beverage was a natural flavor substances with high antioxidant activity and non-toxicity.

RESUMO Há alguns problemas, tais como equipamentos antiquados e em menores quantidades em instalações esportivas na Comunidade urbana, o que dificulta que os recursos de exercícios físicos continuem atendendo as necessidades de atividades físicas dos moradores das comunidades. A abertura de recursos desportivos universitários pode atenuar, em certa medida, o problema da dificuldade dos moradores de praticar atividades físicas. A fim de explorar os problemas enfrentados pela abertura dos recursos desportivos universitários, este estudo estabeleceu o modelo de processo hierárquico analítico baseado no processo hierárquico analítico (Analytic Hierarchy Process — AHP) e na Lei Delphi no contexto do serviço público nacional de atividades físicas, combinado com o método de inquérito por questionário para estudar os fatores que influenciam a abertura dos recursos esportivos universitários. O modelo modificado pelo método Delphi contém 6 fatores influenciadores de primeiro nível e 22 fatores influenciadores de segundo nível. Constata-se que o fator de primeiro nível mais importante é o fator físico dos recursos esportivos universitários, e o fator de segundo nível mais importante é a disposição espacial dos recursos esportivos universitários. Os resultados mostram que a melhoria das instalações físicas dos recursos desportivos universitários, a melhoria do modo de gestão dos recursos desportivos e o aumento dos subsídios financeiros e a redução e isenção de impostos são úteis para aumentar a disponibilidade da abertura dos recursos desportivos e melhorar a qualidade dos recursos desportivos abertos. Espera-se que este estudo possa promover o processo de abertura dos recursos esportivos universitários e promover a melhoria contínua do nível de serviço de recursos esportivos.

ABSTRACT There are some problems such as few and old equipment in urban community sports fitness facilities, which makes it difficult for community fitness resources to continue to meet the fitness needs of community residents. The opening of university sports resources can alleviate the problem of residents' fitness difficulty to a certain extent. In order to explore the problems faced by the opening of university sports resources, this study established the analytic hierarchy process model based on the analytic hierarchy process (AHP) and Delphi law in the background of national public service of fitness, and combined with the questionnaire survey method to study the influencing factors of opening of college sports. The model modified by the Delphi method contains 6 first-level and 22 second-level influencing factors. It is found that the most important factor in the first level is the hardware factor of college sports resources, and the most important factor of the second level is the spatial layout of university sports resources. The results show that improving the hardware facilities of university sports resources, improving the management mode of sports resources, and increasing the targeted financial subsidies and tax reduction and exemption are helpful to enhance the willingness to open sports resources and improve the quality of opened sports resources. It is hoped that this study can promote the opening of college sports resources and promote the continuous improvement of the service level of sports resources.

In order to improve the compatibility and dispersion of antimony trioxide nanoparticles (nano-Sb2O3) in polyvinyl chloride (PVC) and improve the comprehensive properties of PVC, a novel type of nano-Sb2O3/DOP/PVC composites was prepared by using nano-Sb2O3 modified by dioctyl phthalate (DOP) as flame retardant and the mechanical properties and flame-retardant properties of the composites were studied. The results indicated that nano-Sb2O3 particles modified by appropriate DOP could improve the flame retardancy and tensile strength of PVC matrix composites due to good dispersibility and interface compatibility of nano-Sb2O3 in PVC matrix. The PVC matrix composites containing 2 wt% nano-Sb2O3 particles modified by DOP with 5 wt% of usage had excellent flame retardancy, which LOI was 29.8% and its UL94 grade was V-0 level. And the heat release rate,smoke production rate, CO content and CO2 content of the composites was significantly reduced. Meanwhile, the tensile strength and Young's modulus of the composites were 15.9 MPa and 2.1 GPa, respectively.

OBJECTIVES: This study explored the relationship between skipping breakfast and physical fitness in a group of school-aged adolescents in China. METHODS: This cross-sectional study from the Chinese National Surveillance on Students’ Constitution and Health (CNSSCH) survey in Ningbo, China, used a standardized questionnaire to assess the frequency of breakfast consumption. Physical fitness was measured through standing long jump, 50-m sprint, 1,000 (or 800)-m run, and vital capacity tests. Multiple linear regression analysis was used to investigate the relationship between the frequency of breakfast consumption and physical fitness. RESULTS: Our study included a total of 1,849 school-aged adolescents (aged 15.53±1.80 years). Among boys, non-breakfast-skippers had good scores for 50-m sprints, 1,000-m run, and vital capacity tests when compared with breakfast skippers (all p<0.05). Among girls, non-breakfast-skippers had a good scores for the standing long jump test compared with breakfast skippers (p=0.003). The multiple linear regression model showed that not skipping breakfast was positively associated with vital capacity (β=-173.78, p=0.004) and inversely associated with 50-m sprint (β=-0.12, p=0.018) and 1,000-m run times (β=-8.08, p=0.001) in boys. CONCLUSION: The results of this cross-sectional study revealed that skipping breakfast might be associated with lower physical fitness in Chinese adolescents aged 13-18 years, especially boys. Breakfast consumption should be promoted among Chinese school-aged boys.

Rheumatoid arthritis (RA) is an autoimmune disease of knee joints involving pain and inflammation. Rhoifolin is a plant flavonoid known to have antioxidant and anti-inflammatory properties. This study was taken to identify the effect of rhoifolin on complete Freund’s adjuvant (CFA)-induced arthritis in the rat model. Treatment with rhoifolin (10 and 20 mg/kg) showed a significant improvement in the overall health parameters such as paw edema and weight loss. This improvement in morphological parameters corroborated the findings with gross morphological changes observed in the histopathological analysis. Rhoifolin treatment also caused a significant decrease in oxidative stress, evident from changes in intracellular levels of glutathione, glutathione peroxidase, malondialdehyde, and superoxide dismutase in the articular cartilage tissue. Moreover, proinflammatory cytokines, tumor necrosis factor (TNF)-α, interleukin(IL)-1β, and IL-6 showed a significant downregulation of gene expression and intracellular protein concentration levels. The NF-κB pathway showed a significant attenuation as evident in the significant reduction in the levels of NF-κB p65 and p-IκB-α. These results indicated that rhoifolin can be a natural therapeutic alternative to the extant regimens, which include non-steroidal anti-inflammatory drugs and immunosuppressants. Additionally, the antioxidant and anti-inflammatory action of rhoifolin was probably mediated by the NF-κB pathway. However, the exact target molecules of this pathway need to be determined in further studies.

Abstract Background: Reports regarding the causative drugs of drug-induced cutaneous adverse reactions in China are indistinct, such that different regions have reported the spectrum of drugs differs substantially in different clinical conditions. Objective: To explore the causative drugs that led to cutaneous reactions. Methods: Adverse drug reaction reports from central China were collected and divided into cutaneous adverse reactions and severe cutaneous adverse reactions groups. Cases were reviewed retrospectively for causative drugs. Results: The male:female ratio was equal in both cutaneous adverse reactions and severe cutaneous adverse reactions. In cutaneous adverse reactions (n = 482), the highest incidence happened between 51 and 60 years of age and the top three causative drugs were antibiotics (48%), Chinese medicine (16%), and allopurinol (9%). In severe cutaneous adverse reactions (n = 126), the highest incidence happened between 41 and 50 years of age and the top three causative drugs were sedative-hypnotics and antiepileptics (39%), antibiotics (22%), and allopurinol (15%). Carbamazepine was the most frequently used single-drug (16/18) in sedative-hypnotics and antiepileptics. β-lactams were the most frequently used antibiotics that induced both cutaneous adverse reactions and severe cutaneous adverse reactions. Study limitations: The small sample size, retrospective design, collection of cutaneous adverse reactions and severe cutaneous adverse reactions at different time frames and locations, and exclusion of patients taking more than five medications are limitations of the study. Conclusions: Gender does not affect cutaneous adverse reactions and severe cutaneous adverse reactions. The top three drugs to induce cutaneous adverse reactions are antibiotics, Chinese medicine, and allopurinol, while those that triggered severe cutaneous adverse reactions are sedative-hypnotics and antiepileptics, antibiotics, and allopurinol. Carbamazepine is the most frequent single drug that induces severe cutaneous adverse reactions. β-lactams are the most frequently used antibiotics that induce both cutaneous adverse reactions and severe cutaneous adverse reactions.

ABSTRACT: An imaginary part model of soil dielectric constant for predicting the soil salinity status was developed based on a series of relations between dielectric imaginary part and soil bulk conductivity, soil bulk conductivity and soil solution electrical conductivity, and soil solution electrical conductivity and ion contents in soil using pot trials with different soil salinity levels in the 2008 growing season. This model was calibrated and tested with data from the 2009 growing season. The results showed that the inverted values of the total concentration of salt (Sc), Cl−, and Ca2+ at low frequencies (P-band of microwave observations) from the imaginary part model fitted well with the observed values, since root mean square errors (RMSEs) were 0.34 g kg−1, 0.09 g kg−1 and 0.13 g kg−1, respectively, but the inversion effect of Na+ was relatively poor. Moreover, the Sc, Cl−, and Na+ could be well inverted at high frequencies (C-band of microwave observations), since RMSEs were minor, with values of 0.25 g kg−1, 0.02 g kg−1, and 0.15 g kg−1, respectively. The close fit between the observed and inverted values indicated that the present models could be used to estimate soil ion content quickly and reliably under different saline conditions, which, when suitable measures are taken, can be used to reduce the effects of soil salinity on crop growth.

ABSTRACT Objective: The aim was to characterize blood glucose fluctuations in patients with fulminant type 1 diabetes (FT1DM) at the stable stage using continuous blood glucose monitoring systems (CGMSs). Subjects and methods: Ten patients with FT1DM and 20 patients with classic type 1 diabetes mellitus (T1DM) (the control group) were monitored using CGMSs for 72 hours. Results: The CGMS data showed that the mean blood glucose (MBG), the standard deviation of the blood glucose (SDBG), the mean amplitude glycemic excursions (MAGE), the blood glucose areas and the percentages of blood glucose levels below 13.9 mmol/L were similar between the two groups. However, the percentage of blood glucose levels below 3.9 mmol/L was significantly higher in the FT1DM group compared to the T1DM group (p < 0.05). The minimum (Min) blood glucose level in the FT1DM group was significantly lower than that of the T1DM group (p < 0.05). Patients with FT1DM had severe dysfunction of the islet beta cells and alpha cells compared to patients with T1DM, as indicated by lower C-peptide values and higher glucagon/C-peptide values. Conclusion: In conclusion, patients with FT1DM at the stable stage were more prone to hypoglycemic episodes as recorded by CGMSs, and they had a greater association with severe dysfunction of both the beta and alpha islet cells compared to patients with T1DM.
