Objective: To establish evidence-based, safe and efficient management of HIV-reactive blood donors by investigating safe and feasible assessment strategies for HIV-reactive blood donors based on routine blood screening data. Methods: The data of blood screening, supplementary testing, follow-up and CDC confirmation for HIV-reactive blood donors in our center from 2014 to 2024 were analyzed systematically to confirm HIV infection and identify infection status. Results: There were 1 235 samples (0.13%, 1 235/928 000) reactive in HIV blood screening over the 11-year period. A-mong them, 199 donors (16.11%) in asymptomatic HIV infection (HIV Ag/Ab++&HIV RNA+), 2(0.16%) as acute early HIV infection (HIV Ag/Ab+-&HIV RNA+) and 7(0.57%) as window-period infection (HIV RNA positive only) were confirmed. Donors with the result of HIV Ag/Ab+-&HIV RNA-(single-positive) were all excluded for HIV infection, while 1 in 6 HIV Ag/Ab++&HIV RNA-donors (double-positive) was confirmed to have HIV infection. When HIV Ag/Ab reagents were used continuously before and after the follow-up, it's observed in one reagent that the proportion of negative results in subsequent follow-up in single-positive donors who had negative results in the first sampling was significantly higher than the proportion of negative results in subsequent follow-up in those initially single-positive (P<0.05). But no significant difference was observed in another reagent (P>0.05). When reagents were changed in follow-up, the rate of singlepositive donors with negative results in the first sampling reached 96.7%, which was significantly higher than the negative rate of those without reagent changing in follow-up (P<0.05). Conclusion: Based on the serological and nucleic acid testing results of HIV blood screening, the confirmation of HIV infection and identification of infection status can be achieved accurately and efficiently. All HIV Ag/Ab+-&HIV RNA-donors were confirmed as false positive, and should be maintained their eligibilities for blood donation, but recommended to pass the retest before next donation. Using a different reagent for retesting helps improve the eligible rate. HIV Ag/Ab++&HIV RNA-donors should be deferred permanently due to the risk of true positivity.

ObjectiveTo explore the diagnostic value of resting-state functional magnetic resonance imaging (rs-fMRI) for mild cognitive impairment (MCI) stage of Alzheimer's disease (AD), and to investigate the changes in brain functional connectivity in default mode network (DMN) and medial temporal lobe (MTL) regions. MethodsLiteratures were retrieved from multiple databases including CNKI, PubMed, Medline, and Embase, etc. from January, 2020 to October, 2025, investigating the changes in functional connectivity of DMN and MTL in patients with MCI compared to health control (HC) using rs-fMRI. Two researchers independently screened and extracted the literatures and methodological quality was assessed using QUADAS-2. Review Manager 5.4 was used to perform a meta-analysis of neuroimaging indicators in MCI patients and HC subjects. Stata and SDM were utilized to summarize diagnostic efficacy and brain functional connectivity, calculating the over all sensitivity, specificity and summary receiver operating characteristic-area under the curve (SROC-AUC). Deeks funnel plots were drawn, literature weights were analyzed, and subgroup analyses were conducted. ResultsA total of ten literatures were ultimately included, involving 1 010 patients with MCI and 1 714 HC subjects. MCI patients showed decreased or abnormal blood oxygen level dependence signals in DMN, focusing on bilateral medial prefrontal cortex (mPFC) and posterior cingulate cortex. The SROC-AUC was 0.91. In MTL, there was a characteristic decrease of spontaneous neural functional connectivities between the hippocampus and other regions, reflecting the obstruction of information transmission from episodic memory to the central nodes. Abnormal functional connectivity in DMN and MTL resulted in compensatory resting-state functional connectivity enhancement in other subnetworks or local functional connections, such as frontoparietal network and the hippocampal-parietal network. Abnormal activation of mPFC suggested atrophy of the hippocampus or abnormal brain function. The decline in functional connectivity between DMN and MTL indicated impairment of memory and information processing in the early stage. ConclusionThe early functional decoupling between DMN and MTL is a crucial neural mechanism at the MCI stage of AD, providing important neuroimaging evidence for the early diagnosis of AD.

OBJECTIVE To compare the risk of pneumonitis and interstitial lung disease （ILD） associated with different antibody-drug conjugates （ADC） in the treatment of breast cancer. METHODS CNKI， VIP， PubMed， Embase and other Chinese and English databases， and ClinicalTrials.gov were searched from the inception to June 15， 2025. Randomized controlled trials （RCT） about pneumonitis and ILD associated with ADC （T-DM1， T-DXd， SG， Dato-DXd， SHR-A1811，ARX788， and T-Duo） in the treatment of breast cancer were included. After literature screening， data extraction， and quality assessment， a network meta-analysis was conducted using Stata 17.0 software， and the surface under the cumulative ranking curve（SUCRA） of all interventions were ranked. RESULTS A total of 19 RCTs involving 10 556 patients were included. The overall incidence of pneumonitis with ARX788 and T-DXd was significantly higher than that with T-DM1， T-DM1 plus TPC（T-DM1combined with pertuzumab or atezolizumab）， TPC（treatment of primary care）， and SG （ P ＜0.05）， for grade 1-2 pneumonitis， ARX788 and T-DXd showed significantly higher incidence than T-DM1， T-DM1 plus TPC， and TPC （ P ＜0.05）. For both indicators， ARX788 and T-Duo were ranked as the top two by SUCRA. For the incidence of grade ≥3 pneumonitis， T-DXd and T-DM1 were significantly higher than SG （ P ＜0.05）， T-Duo and Dato-DXd were ranked as the top two by SUCRA. For overall incidence of ILD， ARX788 was significantly higher than T-DM1， SHR-A1811， TPC， and SG （ P ＜0.05）， for the incidence of grade 1-2 ILD， ARX788 was significantly higher than T-DM1， SHR-A1811， and TPC （ P ＜0.05）， for the incidence of grade ≥3 ILD， ARX788 was significantly higher than TPC （ P ＜0.05）. For three indicators above， ARX788 and T-DXd combined with pertuzumab were ranked as the top two by SUCRA. CONCLUSIONS Compared with other ADCs， ARX788 and T-Duo are associated with a higher risk of pneumonitis and ILD in patients with breast cancer.

ObjectiveTo investigate the optimal termination time for acupuncture in treating patients with acute peripheral facial paralysis and its cost-effectiveness. MethodsA total of 120 eligible patients with acute-stage peri-pheral facial paralysis were randomly assigned to either the mild dysfunction termination group and the complete recovery termination group， with 60 patients in each group. Both groups received the standard acupuncture treatment protocol. Treatment in the mild dysfunction termination group was terminated when the Sunnybrook facial grade scale （SFGS） score first reached or exceeded 83 points， while that in the complete recovery termination group was terminated when the SFGS score first reached or exceeded 95 points. Assessments were conducted before treatment， 6 and 12 months after onset. SFGS， facial disability index （FDI） including physical function （FDIp） and social function （FDIs）， self-rating anxiety scale （SAS）， and self-rating depression scale （SDS） scores were assessed before treatment， and 6 and 12 months after onset. Any acupuncture-related adverse events during treatment were recorded for safety evaluation. Treatment sessions and medical costs including direct costs， indirect costs， insurance coverage， total societal costs， and patient out-of-pocket expenses were also recorded， and an economic evaluation was conducted including cost-effectiveness ratio （CER） and incremental cost-effectiveness ratio （ICER）. ResultsUltimately， 56 patients in the mild dysfunction termination group and 55 in the complete recovery termination group completed the follow-up. At 6 and 12 months after onset， SFGS and FDIp scores in both groups improved significantly while FDIs， SAS and SDS scores decreased （P＜0.05）. Comparison of scores between groups 6 months and 12 months after onset showed no statistically significant differences （P＞0.05）. During the trial， the incidence of adverse events was 13.3% （8/60） in the mild dysfunction termination group and 18.3% （11/60） in the complete recovery termination group， with no statistically significant difference （P＞0.05）. The number of treatment sessions， total social costs， and out-of-pocket expenses in the mild dysfunction termination group were significantly lower than those in the complete recovery termination group （P＜0.05）. The CER of the mild dysfunction termination group in SFGS， FDIp， FDIs， SAS， and SDS scores was lower than that of the complete recovery termination group. The ICER analysis showed that continuing treatment until full recovery incurred an additional cost of 573.30 CNY/point in SFGS improvement， whereas 1-point improvement in FDIp， FDIs， SAS， and SDS required 21,355.25 CNY， 1779.60 CNY， 3713.96 CNY， and 2755.52 CNY， respectively. ConclusionFor acupuncture in treating acute peripheral facial palsy， terminating treatment when mild dysfunction is achieved yields long-term efficacy comparable to that of continuing treatment until complete recovery， while significantly reducing medical costs and socioeconomic burden.

Objective: To investigate the correlation between color parameters (L^*, a^*, b^*, Eab^*) and the contents of reducing sugars, total polysaccharides, total oligosaccharides, as well as four saccharides (fructose, glucose, sucrose, and kestose) during the nine cycles of steaming and sun-drying processing of Polygonatum kingianum, and to preliminarily explore the optimal processing duration.
Methods: The color changes were objectively evaluated using a colorimeter. The anthrone-sulfuric acid method was employed to determine total polysaccharides and oligosaccharides. The 3,5-dinitrosalicylic acid (DNS) colorimetric method was used to measure total reducing sugar content. High-performance liquid chromatography coupled with charged aerosol detection (HPLC-CAD) was applied for quantitative analysis of fructose, glucose, sucrose, and kestose. Multivariate statistical analysis was conducted to assess samples from different processing stages.
Results: Significant variations in color and component contents were observed across processing stages. The herbal pieces progressively darkened with increased processing cycles: brightness (L^*) and total color difference (Eab^*) initially decreased then stabilized, while a^* (red-green) and b^* (yellow-blue) values first increased then declined. Total polysaccharides and oligosaccharides showed overall decreasing trends, whereas reducing sugars initially increased before stabilizing. Fructose and glucose levels rose continuously, while sucrose and kestose decreased progressively, becoming undetectable after five cycles.
Conclusion: The chromatic alteration and saccharide composition of P. kingianum showed significant correlation with processing duration. Both total color difference (Eab^*) and reducing sugar content stabilized after four processing cycles (12 hours), suggesting that four cycles of steaming and sun-drying may represent the optimal processing duration.

Objective To investigate the effects of scribble planar cell polarity protein(SCRIB)on proliferation,apoptosis,and autophagy of glioblastoma(GBM)and elucidate its potential underlying mechanisms.Methods The expression level of SCRIB in GBM tissue was queried through the Biomarker Exploration of Solid Tumors(BEST)database.Lentivirus-mediated shRNA interference was employed to downregulate SCRIB expression in human glioblastoma cell lines U87 and U251,which were divided into negative control group(mock)and SCRIB shRNA interference groups(kd1 and kd2).SCRIB expression levels were detected using Western blotting(WB)and quantitative polymerase chain reaction(qPCR).EdU incorporation and cell apoptosis rates were detected by flow cytometry(FCM).CCK-8 assay was used to detect the proliferation vitality of U87 and U251 cells,and WB was used to detect the expression of proliferation-related proteins.Immunofluorescence(IF)staining was conducted to detect the expression of autophagy-related proteins LC3 and p62,followed by quantitative analysis across multiple fields.WB was also used to detect the expression levels of LC3,p62,and proteins in the JAK-STAT3 signaling pathway.Results Compared with that of normal tissues,SCRIB mRNA expression level was significantly upregulated in GBM tissues(P＜0.05).FCM results showed that EdU incorporation rates were significantly reduced(P＜0.001)while cell apoptosis rates were markedly increased(P＜0.001)in U87 and U251 cells with SCRIB knockdown.CCK-8 results indicated that compared with the mock group,the proliferation vitality of U87 and U251 cells in the SCRIB knockdown group was significantly downregulated(P＜0.001).IF staining showed that LC3 fluorescence aggregation was significantly enhanced(P＜0.001),while p62 fluorescence aggregation was significantly reduced(P＜0.001)in the SCRIB knockdown group.WB results showed that compared with the mock group,the protein expression levels of p27,LC3,p-JAK2 and p-STAT3 were upregulated,while C-Myc,Cyclin D1,MCM,PCNA and p62 were downregulated,with statistically significant differences(P＜0.05).Conclusion Downregulation of SCRIB may induce autophagy and apoptosis in glioblastoma cells by inhibiting the JAK-STAT3 signaling pathway,thereby suppressing cell proliferation.

Background and Aims:Laparoscopic pancreaticoduodenectomy(LPD)has become a preferred approach for periampullary tumors,yet delayed gastric emptying(DGE)remains a frequent complication that hampers postoperative recovery.The nasojejunal feeding tube(NJT)is commonly used for early enteral nutrition,but its impact on DGE is controversial.This study aimed to evaluate whether intraoperative NJT placement increases the risk of DGE after LPD and to assess its influence on postoperative recovery outcomes.Methods:A retrospective cohort of 319 patients who underwent LPD at Provincial Hospital Affiliated to Shandong First Medical University from April 2017 to November 2023 was analyzed.Patients were divided into two groups based on intraoperative NJT placement(NJT group,n=200;non-NJT group,n=119).The incidence of DGE and postoperative outcomes were compared.Multivariate logistic regression and propensity score matching(PSM)were performed to identify independent risk factors for DGE.Results:The incidence of grade B/C DGE was significantly higher in the NJT group than in the non-NJT group(36.5%vs.21.8%,P=0.006).NJT placement was associated with longer postoperative hospital stay and higher hospitalization costs(both P<0.05).Multivariate analysis revealed intraoperative NJT placement(OR=1.960,95%CI=1.142-3.363,P=0.015)and intraoperative blood loss>400 mL(OR=1.921,95%CI=1.155-3.194,P=0.012)as independent risk factors for DGE.These findings were consistent after PSM.Conclusions:Prophylactic intraoperative NJT placement confers no additional benefit for postoperative recovery after LPD and is associated with a higher risk of DGE,prolonged hospitalization,and increased medical costs.Routine NJT placement should therefore be avoided,and individualized strategies should be adopted to minimize postoperative complications and enhance recovery.

Objective:To investigate the independent risk factors for the occurrence of early urinary incontinence after Holmium laser enucleation of the prostate(HoLEP), and to construct a clinical risk predictive model for postoperative urinary incontinence.Methods:A retrospective analysis was conducted on the clinical data of 384 patients who underwent HoLEP between February 2019 and July 2024 at the Second Affiliated Hospital of Zhengzhou University. The cohort had a mean age of (68.3 ± 6.5) years, with a body mass index (BMI) of 22.45 (20.11, 24.39) kg/m 2. The median duration of lower urinary tract symptoms was 60 (36, 60) months. Of the patients, 104 (27.1%) had a history of diabetes mellitus, 139 (36.2%) had hypertension, and 54 (14.1%) had a preoperative indwelling urinary catheter. Additionally, 136 patients (35.4%) had a preoperative prostate-specific antigen (PSA) level ≥ 4 ng/ml, and 197 patients (51.3%) had a preoperative residual urine volume ≥ 50 ml. The International Prostate Symptom Score (IPSS) was ≥ 19 in 227 cases (59.1%). Preoperative detrusor instability was observed in 169 cases (44.0%), with a median maximal urinary flow rate of 5.9 (4.5, 9.3) ml/s and a median urinary flow rate of 4.0 (3.4, 7.3) ml/s. Moreover, 148 cases (38.5%) had a preoperative prostate volume ≥ 65 ml, and the preoperative median maximum urethral length (MUL) was 13.99 (12.40, 16.24) mm. Postoperative follow-up allowed for division of the patients into two groups: those with recovery of urinary control function and those with early postoperative urinary incontinence. The general characteristics of both groups were compared. Independent risk factors for early postoperative urinary incontinence were identified through multifactorial logistic regression. Variables with statistically significant differences were included in a column chart model created using R software. Internal validation was performed through repeated sampling with the Bootstrap method to assess the model's discriminative ability. Calibration curves were plotted to examine the consistency between predicted and actual outcomes, and the Hosmer-Lemeshow test was used to evaluate the model's fit. Results:This study included 384 patients, with 313 in the urinary control function recovery group and 71 in the early incontinence group. There were statistically significant difference between the two groups in age [≥70 years old: 91 (29.1%) vs. 33 (46.5%)], prostate volume [≥65 ml: 110 (35.1%) vs. 38 (53.5%)], MUL [14.21 (12.63, 16.24) mm vs. 13.12 (12.21, 13.95) mm], and non-inhibitory contraction of the urethra muscle in both groups [125 (39.9%) vs. 44 cases (62.0%)] ( P < 0.05). No significant differences were observed between the two groups in terms of BMI, disease duration, history of diabetes mellitus, preoperative catheterization, IPSS, preoperative PSA, residual bladder urine volume, maximum urinary flow rate, average urinary flow rate, operative time, or duration of indwelling urinary catheterization ( P > 0.05). Multifactorial logistic regression analysis revealed that age ≥ 70 years ( OR = 0.414, 95% CI 0.230-0.746, P = 0.003), prostate volume ≥ 65 ml ( OR=0.451, 95% CI 0.251-0.812, P=0.008), MUL( OR=0.688, 95% CI 0.590-0.802, P<0.001), and detrusor instability, uninhibited detrusor contraction ( OR=0.526, 95% CI 0.279-0.994, P=0.048) were independent risk factors for early postoperative urinary incontinence following HoLEP. A prediction model was developed based on these findings, and internal validation showed a C-index of 0.753. The calibration curve was close to the ideal curve, indicating that the model has good predictive performance. Conclusions:Age ≥70 years, prostate volume ≥65 ml, MUL, and uninhibited contraction of the urethra muscle were independent influences on early urinary incontinence after HoLEP, and the nomogram constructed in this way had good predictive performance for the risk of developing early urinary incontinence after HoLEP.

Objective:To investigate the expression of lysosome-associated membrane protein 3(LAMP3)and activating transcription factor 4(ATF4)in cervical cancer and their correlation with clinicopathological parameters.Methods:The expression of LAMP3 and ATF4 in normal cervical tissues,cervical intraepithelial lesions,and cervical cancer tissues was detected by SP immunohistochemistry.The relationships between the expression of these two proteins and patient clinicopathological parameters were analyzed,as well as the correlation between LAMP3 and ATF4 expression.Results:LAMP3 was negative or lowly expressed in both normal cervix tissues and high-grade squamous intraepithelial lesions,but highly expressed in cervical cancer tissues(38.3%),showing a statistically significant difference(χ2=14.113,P=0.001).ATF4 was highly expressed in 26.7%of the normal cervix tissues,10.0%of the high-grade squamous intraepithelial lesions,and 58.3%in the cervical cancer tissues,also showing a significant difference(χ2=11.078,P=0.004).In cervical cancer,LAMP3 expression was significantly associated with FIGO stage(χ2=10.139,P=0.006)and lymph node metastasis(χ2=8.475,P=0.004);ATF4 expression was significantly associated with tumor size(χ2=4.578,P=0.032),FIGO stage(χ2=8.971,P=0.009),and lymph node metastasis(χ2=7.881,P=0.005).There was a positive correlation between the expression of LAMP3 and ATF4 in cervical cancer tissues(r=0.388,P=0.002).Conclusion:LAMP3 and ATF4 are highly expressed in cervical cancer tissues and are positively correlated.Both of them play important roles in the development and progression of cervical cancer and could serve as potential therapeutic targets for cervical cancer treatment.
