Objective Explore changes in polysaccharides in Jiangxiangru before and after ginger juice preparation,and evaluate polysaccharide anti-inflammatory and antioxidant activities before and after processing.Methods The contents of Jiangxiangru polysaccharide(JXRPs)and Ginger juice processed of Jiangxiangru polysaccharide(JZJXRPs)before and after processing were determined by phenol-sulfuric acid method.We used the swelling model in rats and endotoxin(LPS)to establish the RAW264.7 mouse macrophage inflammation model.The optimal administration concentration was determined using a cell proliferation(MTT)assay.Enzyme-linked immunosorbent assay(ELISA)were used to measure Interleukin-6(IL-6),Interleukin-12(IL-12),Nitric oxide(NO),Interleukin-4(IL-4),and Interleukin-10(IL-10).Bleeding time of mice by tail cutting was observed to evaluate the hemostatic effect.The ability to remove 1,1-diphenyl-2-picryl-hydrazyl radical(DPPH)and 2,2'-Azinobis-(3-ethylbenzthiazoline-6-sulphonate)(ABTS)was used to evaluate in vitro antioxidant activity.Results The contents of JXRPs and JZJXRPs were 13%and 22%,respectively.In swollen rats at 4 h after injection,compared with the model group,200 mg/kg JXRPs and 100 mg/kg JZJXRPs significantly reduced rat swelling(P<0.05).In vitro anti-inflammation assessment showed that the polysaccharides before and after processing significantly inhibited secretion of IL-6,IL-12,and NO(P<0.01)and promoted secretion of IL-4 and IL-10(P<0.01),and also that processing post-effects were stronger.The hemostatic experiment show that,compared with the control group,JXRPs increased hemostasis,but without a significant difference,and no significant difference was found using JZJXRPs,although high doses showed a trend to increase hemostasis.In vitro antioxidant activity showed that JXRPs and JZJXRPs had different scavenging abilities for DPPH and ABTS with IC50 values of JXRPs of 0.2215 and 0.2110 mg/ml,respectively,and IC50 values of JZJXRPs of 0.1651 and 0.1884 mg/mL,respectively.Conclusions After Jiangxiangru is produced in ginger juice,it promotes dissolution of polysaccharides and increases polysaccharide content.Anti-inflammatory,hemostasis,and antioxidant capacities are stronger in JZJXRPS than JXRPS,which lays the foundation for follow-up research and clinical applications of JXRPS.

Objective To investigate the effects of MCSO on physiological behavior and antioxidant index in D.melanogaster.Methods One-day-old wild type D.melanogaster was divided into control group,0.25%,0.5%,1%,2%and 4%dose groups,as well as male and female groups.The control group was exposed to the base medium,and each dose group was exposed to the MCSO medium added with 0.25%,0.5%,1%,2%and 4%concentrations,respectively.The optimal dosage concentration and time of administration were investigated by climbing experiment.Then the flies were divided into control group,model group and MCSO group.The model group was established by depriving the flies of sleep through repeated nocturnal light stimulation.Period of drug treatment,appetite test,negative geotaxis ability test,stress test,olfactory memory test,and sleep-wake rhythm detection were used to explore the effects of MCSO on their physiological behavior.The activities of super oxidase dismutase(SOD),catalase(CAT),and malondialdehyde(MDA)were detected by enzyme-linked immunosorbent assay.Results MCSO enhanced the locomotory ability of 30-day-old D.melanogaster(P<0.01),increased the activity of SOD and CAT(P<0.01),and decreased the concentration of MDA(P<0.01).Improve olfactory memory of senile fruit flies.After sleep deprivation,the night sleep time of female Drosophila model group was reduced(P<0.05),and that of male Drosophila model group was reduced(P<0.01).After feeding MCSO,the night sleep time of female drosophila model group was extended(P<0.05),and that of male drosophila model group was extended(P<0.01).Conclusions MCSO had a certain antioxidant effect,prolonging the sleep time and improving the olfactory memory of sleep-deprived Drosophila.

Objective:To explore the status of social alienation among survivors of nasopharyngeal carcinoma and analyze its influencing factors.Methods:This study was a cross-sectional study. From October 2021 to January 2022, 200 survivors of nasopharyngeal carcinoma reviewed in the radiotherapy department of the First Affiliated Hospital of Guangxi Medical University were investigated by General Data Questionnaire, General Alienation Scale (GAS), Cancer Fatigue Scale (CFS) and Self-Perceived Burden Scale (SPBS).Results:The total score of GAS in survivors of nasopharyngeal carcinoma was (37.47 ± 2.88) points. The total scores of GAS were positively correlated with the total score and each dimension score of CFS and SPBS ( r values were 0.312-0.524, all P<0.01). Multivariable linear regression showed that the duration of diagnosis, whether or not having hearing loss, the number of symptoms, cancer fatigue and self-perceived burden were the main influencing factors of social alienation in survivors of nasopharyngeal carcinoma( t values were -3.99-4.86, all P<0.05), which could explain 49% of the total variation. Conclusions:Clinical medical staff should attach importance to social alienation of surviors of nasopharyngeal carcinoma. More attention should be paid to patients with less than one year of diagnosis, a large number of symptoms and hearing loss, and targeted intervention should be conducted to reduce the degree of social alienation of patients and promote their integration into society.

【Objective】 To compare the current standards and explore the influencing factors for hemolysis rate of leukocyte-reduced red blood cells at the end of the preservation period, in order to formulate reasonable internal control indicators. 【Methods】 A retrospective analysis was performed on hemolysis rate of 427 samples of leukocyte-reduced red blood cells at the end of the preservation period in Nanning Blood Center from 2015 to 2022. Compared with the current standard for hemolysis rate at the end of the preservation period (GB 18469-2012 Quality Requirements for Whole Blood and Component Blood), the differences were analyzed, and the factors influncing the hemolysis rate were analyzed in terms of different blood donor groups. 【Results】 1) Among the 427 samples, the hemolysis rate of 418 (97.89%) did not exceed 0.4%, all lower than 0.8%; 2)the hemolysis rate of the male group was higher than that of the female group; 3) the hemolysis rate of the 18-29 years old group was lower than that of the 30-39 year old group and the 40-60 year old group, with statistically significant difference; 4) in terms of occupation, the hemolysis rate of students was the lowest, and the differences between groups were statistically significant; 5) no statistical significance was found in ethnicity and blood type. 【Conclusion】 Statistics indicated that gender, age, blood donation volume and occupation of blood donors were the influencing factors of hemolysis rate. The current standard is obviously higher in the qualified range of blood quality control in Nanning. It is advisable to formulate a reasonable quality control strategy with internal control index of hemolysis rate set <0.4%, which is conducive to making accurate evaluation of internal quality control and ensuring blood safety.
