Objective: To analyze the demographic characteristics of patients with red blood cell transfusion reactions, the usage of red blood cell preparations, and the differences in the composition ratio of adverse reactions based on multi-center data from the Haemovigilance Network, in order to reveal the clinical characteristics of red blood cell transfusion and its underlying issues. Methods: Clinical data of patients who experienced transfusion reactions after red blood cell transfusion in the Haemovigilance Network from 2018 to 2023 were collected. The demographic characteristics of patients who experienced transfusion reactions with different types of red blood cell preparations, the utilization of these preparations, and the differences of the composition ratios of transfusion reactions were analyzed. Count data were expressed as numbers (n) or percentages (%), and comparisons between groups were performed using the Chi-square test. Results: Red blood cell transfusion reactions were more common in females (53.56%), with the majority of patients aged 50-69 years (35.54%). The Han polulation accounted for the vast majority of patients (92.77%), and patients in the hematology and obstetrics/gynecology departments had a relatively high proportion of transfusion reactions (13.26% and 14.26%, respectively). Leukocyte-reduced red blood cells and suspended red blood cells were the most common types of transfusion reactions reported among red blood cell preparations. Allergic reactions and non-hemolytic febrile reactions were the most common transfusion reactions, and there were significant differences in the composition ratios of allergic reactions (χ =869.89, P<0.05) and non-hemolytic febrile reactions (χ =812.75, P<0.05) across various types of red blood cell preparations. Conclusion: There are differences in the demographic characteristics and composition ratio of transfusion reactions among different red blood cell preparations. The management of red blood cell transfusion reactions should be tailored to patient characteristics and conditions, and the selection and use of blood products should be optimized to reduce or avoid the occurrence of transfusion reactions, such as considering the use of washed red blood cells for patients with a history of transfusion allergies or those prone to allergies.

Objective The aim of this study was to evaluate the efficacy and side effects of sacubitril/valsartan in the treatment of patients with chronic kidney disease(CKD)at stage 5 with resistant hypertension,and to explore the cardiovascular benefits and security of medical in the patients.Methods Patients with CKD5 resistant hypertension diagnosed and treated in the First Affiliated Hospital of Guangxi Medical University from September 2020 to March 2022 were selected and divided into the observation group(treated with routine treatment of kidney disease at end-stage and sacubitril/valsartan)and control group(include droutine treatment of renal disease at end-stage and ACEI or ARB drugs)according to treatment strategy.The patients in both two groups were treated with adequate dialysis treatment and conventional drug treatment of renal disease at end-stage.The patients were followed up for at least 3 months,the clinical efficacy of three months after treated with sacubitril/valsartan was observed,and the efficacy indicators and security indicators and adverse cardiovascular events were observed,the occurrence of adverse effects during the period of drug use were compared with the control group.Results A total of 110 patients were included in this study and there were 55 cases in each group.There were no significant differences in gender,age,age of dialysis,etiology,dialysis mode and blood pressure between the two groups(P>0.05).The Systolic blood pressure(SBP),diastolic blood pressure(DBP),b-type urinary natriuretic peptide precursor(Pro-BNP)and cardiac function grade in the observation group after treatment was significantly decreased compared with before treatment.The left ventricular ejection fraction(LVEF)and the ratio of LVEF<50%in the observation group was significantly reduced after treatment(P<0.05).SBP,DBP and Pro-BNP decreased 3 months after treatment compared with the baseline before treatment,and improved significantly in the first month after treatment(P<0.05).The decrease of DBP and BNP before and after treatment was significantly different between the two groups,and the decrease of DBP and BNP was more significant in the observation group(P<0.05).The difference of LVEF and left ventricular end diastolic diameter(LVEDD)between the two groups before and after treatment was statistically significant,and the improvement was more obvious in the observation group(P<0.05).There were no significant differences in the safety indicators of serum potassium,estimated glomerular filtration rate(eGFR)and liver function between two groups before and after treatment(P>0.05).In terms of adverse reactions,only 1 case in the control group developed hyperkalemia within 3 months of follow-up,and no hypotension or other adverse reactions occurred in the two groups.Conclusions The treatment of patients with CKD stage 5 hypertension with sacubitril/valsartan has obvious cardiovascular benefits.Sacubitril/Valsartan has efficacy in lowering blood pressure,improving cardiac function and reducing volume load,with less adverse events and higher safety than control group.

OBJECTIVE To establish a rapid nondestructive detection method for the sporoderm-broken rate of Ganoderma lucidum spore powder by hyperspectral technology combined with chemometrics. METHODS Hyperspectral images of Ganoderma lucidum spore powder samples with different sporoderm-broken rates were collected, and spectral data in the visible-shortwave near-infrared band(397−1 004 nm) range of each sample were calculated after selecting the region of interest. Compared 6 spectral preprocessing methods[standard normal variable transformation, multivariate scattering correction, Savitsky-Golay(SG) smoothing, wavelet transform, SG smoothing+standard normal variable transformation, and SG smoothing+multivariate scattering correction], 5 characteristic band extraction methods(competitive adaptive reweighting, successive projections algorithm, uninformative variables elimination, least angle regression, and genetic algorithm), and 5 algorithms(partial least squares regression, support vector regression, extreme learning machine, multilayer perceptron, and LightGBM) for constructing quantitative correction models to predicts performance. RESULTS The optimal combination was SG smoothing+competitive adaptive reweighted feature band selection+partial least squares. The quantitative correction model established based on the algorithm combination achieved a prediction set coefficient of 0.868 2, and a root mean square error of 0.011 7 for Ganoderma lucidum spore powder samples with a sporoderm-broken rate range of 90%−100%. The selected optimal algorithm combination was applied to construct a quantitative correction model with a sporoderm-broken rate range of 0−100%, the coefficient of determination for the test set was 0.973 1 and the root mean square error was 0.049 3, showing good generalization ability. CONCLUSION The established quantitative detection model can realize the rapid and non-destructive detection of the sporoderm-broken rate of Ganoderma lucidum spore powder, which provides technical support for the quality control of Ganoderma lucidum spore powder and its products.

ObjectiveAlthough expression of the TEAD1 protein in preadipocytes has been established, its function remains unclear. In this study, we sought to detect transcripts of TEAD1 in chicken and to examine the effects of this protein on the proliferation, migration, apoptosis, and differentiation of immortalized chicken preadipocyte cell lines (ICP1). MethodsThe full-length sequence of the TEAD1 gene was cloned and the two transcripts were subjected to bioinformatics analysis. The subcellsular localization of TEAD1 transcripts was determined based on indirect immunofluorescence. The effects of TEAD1 transcripts overexpression on the proliferation of ICP1 cells were examined by RT-qPCR, CCK-8, and EdU assays; the effects of TEAD1 transcripts on ICP1 cells migration were examined based on the scratch test; and the effects of TEAD1 transcripts overexpression on ICP1 cells apoptosis were analyzed using apoptosis-Hoechst staining and RT-qPCR. The expression of TEAD1 transcripts in different tissues, cells lines, and ICP1 at different periods of differentiation was analyzed by RT-qPCR. The effects of TEAD1 transcripts overexpression on lipid droplet accumulation and adipogenic-related gene expression in ICP1 cells were analyzed based on Oil Red O and BODIPY staining, RT-qPCR, Western blot, and dual-luciferase reporter gene assays. Finally, the content of triglyceride (TG) was measured in TEAD1 overexpressed ICP1 cells. ResultsThe full-length TEAD1 was cloned and two TEAD1 transcripts were identified. The TEAD1-V1 protein was found to be localized primarily in the cell nucleus, whereas the TEAD1-V2 protein is localized in the cell cytoplasm and nucleus. The overexpression of both TEAD1-V1 and TEAD1-V2 significantly inhibited the proliferation of ICP1 cells. Whereas the overexpression of TEAD1-V1 promoted ICP1 cell migration, the overexpression of TEAD1-V2 had no significant effects on ICP1 migration; the overexpression of both TEAD1-V1 and TEAD1-V2 significantly promoted the apoptosis of ICP1 cells. We found that the different transcripts of TEAD1 have similar expression pattern in different tissues and cells lines. During induced preadipocyte differentiation, the expression of these genes initially declined, although subsequently increased. Overexpression of TEAD1-V1 promoted a significant reduction in lipid droplet formation and inhibited C/EBPα expression during the differentiation of ICP1 cells (P<0.05). However, the overexpression of TEAD1-V2 had no significant effect on lipid droplet accumulation or the expression of adipogenic-related proteins (P>0.05). Overexpression of TEAD1-V1 significantly decreased triglyceride content in ICP1 cells (P<0.05), while overexpression of TEAD1-V2 had no effect on triglyceride content in ICP1 cells (P>0.05). ConclusionIn this study, for the first time, identified two TEAD1 transcripts. Overexpressed transcripts TEAD1-V1 and TEAD1-V2 both inhibited the proliferation of chicken preadipocytes and promoted apoptosis of chicken preadipocytes. TEAD1-V1 inhibited the differentiation of preadipocytes and promoted the migration of preadipocytes, while TEAD1-V2 had no effect on the differentiation and migration of preadipocytes.

Endo-periodontal lesions(EPLs)involve both the periodontium and pulp tissue and have complicated etiologies and pathogenic mechanisms,including unique anatomical and microbiological characteristics and multiple contributing factors.This etiological complexity leads to difficulties in determining patient prognosis,posing great challenges in clinical practice.Furthermore,EPL-affected teeth require multidisciplinary therapy,including periodontal therapy,endodontic therapy and others,but there is still much debate about the appropriate timing of periodontal therapy and root canal therapy.By compiling the most recent findings on the etiology,pathogenesis,clinical characteristics,diagnosis,therapy,and prognosis of EPL-affected teeth,this consensus sought to support clinicians in making the best possible treatment decisions based on both biological and clinical evidence.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

Objective:To introduce a surgical method involving the indwelling of double-J tubes(DJT)in the seminal vesicles after transurethral seminal vesiculoscopy(TSV)in order to reduce the recurrence of refractory ejaculatory duct obstruction(EDO).Methods:This randomized controlled trial included 67 EDO patients undergoing TSV in our hospitals,27 with(the trial group)and 29 without postoperative indwelling of DJTs in the seminal vesicles(the control group).We collected the general information on the pa-tients and TSV-related parameters,including age,body mass index(BMI),preoperative use of antibiotics,history of urinary tract dis-ease,operation time,hospital stay and intra-and postoperative complications,and performed comparative analyses particularly on the surgical effect,complications,recurrence rate and time to recurrence in the two groups of patients.Results:The patients in the trial and control groups were followed up for(40.5±10.6)and(32.5±14.8)months,respectively.There were no statistically signifi-cant differences in the baseline data,intra-and postoperative complications,and postoperative hospital days between the two groups(P＞0.05).Compared with the controls,the patients in the trial group showed a significantly shorter operation time([62.8±6.1]vs[49.5±7.7]min,P＜0.05)and a lower recurrence rate than the controls(18.5％vs 44.8％,P＜0.05),but with no statisti-cally significant difference in the median time to recurrence(21.0 mo vs 22.0 mo,P＞0.05).Conclusion:The novel technique of indwelling double-J tubes in the seminal vesicles after TSV can significantly reduce the recurrence rate of refractory EDO.

Motion sickness refers to a multi-system physiological syndrome caused by abnormal acceleration and motion vision scene immersion.It occurs commonly in transportation,military operations,space exploration and other fields.This article reviews recent advances in mechanism,prediction and assessment as well as control measures for motion sickness,and discusses possible research direction of motion sickness in the future.The biological basis for motion sickness sensory conflict theory has been expanded;genomic sequencing and artificial intelligence techniques have been used as novel tools for motion sickness prediction and evaluation.Acclimatization training,anti-motion sickness medication and non-drug symptom control measures used in combination is the key for motion sickness prevention and treatment.

Objective To explore the improving effects of motion sickness acclimatization training methods,namely sinusoidal vertical oscillation stimulation and sinusoidal vertical oscillation stimulation combined with visual virtual reality(VR)swell stimulation,on cognitive performance of individuals with extremely severe motion sickness.Methods A total of 90 individuals with extremely severe motion sickness screened by the Graybiel score during 6 h navigation were randomly divided into vertical group,vertical+VR group,and control group(n=30).The abilities of vigilance,memory,rapid calculation,information processing and visual manipulation were evaluated before and after the acclimatization training using a self-developed cognitive performance evaluation software.Results On the 1st day of training,the numbers of missed targets of the vertical group and vertical+VR group were increased in the vigilance test;the reaction time was prolonged in the short-term memory,rapid calculation,information processing and visual manipulation tasks;and the efficiency of rapid calculation was reduced.After acclimatization training,the numbers of missed targets were reduced to the baseline level in the vertical and vertical+VR groups,and the reaction time in the short-term memory,rapid calculation,information processing and visual manipulation tasks and the efficiency of rapid calculation were improved.Conclusion Motion sickness caused by vertical oscillation stimulation or vertical oscillation combined with visual VR swell stimulation can decrease vigilance,short-term memory,rapid calculation,information processing and visual manipulation abilities.Motion sickness acclimatization training can significantly improve the above cognitive abilities.

Objective To study the acclimatization time and effects for preventing motion sickness under sinusoidal vertical oscillation stimulation,visual virtual reality(VR)swell stimulation,and their combined stimulation.Methods Totally 120 individuals with extremely severe motion sickness during 6 h navigation were randomly divided into 4 groups(n=30):vertical group,VR group,vertical+VR group,and control group.The severity of symptoms during the training period was assessed daily by Graybiel scale,and the number of drops from flexible treadmill in the VR group was recorded.The Graybiel score of 0 for 3 d and/or the number of drops for 0 were considered as complete acclimatization.The training effect was validated by navigation under more severe sea conditions.Results The Graybiel scores of the vertical group and vertical+VR group,as well as the number of drops of the VR group were decreased with the increase of training days,and reached the acclimatization level on the 3rd,5th,and 2nd training day,respectively.The longest acclimatization time in the vertical,vertical+VR,and VR groups was 8,8,and 5 d,with an average acclimatization time of 3.6,3.9,and 2.7 d,respectively;the acclimatization rates within 5 d were 93.33％(28/30),76.67％(23/30),and 100.00％(30/30),respectively;the proportions of individuals with effective acclimatization training in the verification voyage were 86.67％(26/30),96.67％(29/30),and 66.67％(20/30),respectively;and the training efficiency was 85.19％,96.30％,and 62.97％,respectively.Conclusion Three training methods all have effects on motion sickness acclimatization,and the acclimatization period is 5-8 d.The acclimatization effects of the vertical oscillation and vertical oscillation+VR training are better than the VR training.
