Objective: To evaluate the practical effectiveness of confidential unit exclusion (CUE) in ensuring blood safety in Zhengzhou, analyze its application characteristics and existing problems, and provide a basis for optimizing blood safety management strategies. Methods: A retrospective analysis was conducted on CUE data handled by Henan Red Cross Blood Center from January 2019 to December 2024. Parameters such as the number of cases, demographic characteristics, reasons for exclusion, and time of report were statistically analyzed and compared with those of non-CUE. Results: From 2019 to 2024, the CUE reporting rate in Zhengzhou was 0.002 6% (40/1 547 666). CUE donors were predominantly male (65.00%, 26/40), aged 18-34 years (47.50%, 19/40), had college degree orabove (50.00%, 20/40), and were employees of enterprises or public institutions (32.50%, 13/40). Among the 40 CUE blood units, only one was reactive for anti-TP, while all others were qualified. The main reasons for CUE were recent vaccination (32.50%, 13/40), medical conditions unsuitable for donation (27.50%, 11/40), and high-risk sexual behavior (17.50%, 7/40). A total of 70.00% of reports occurred within 24 hours after donation, during which none of the corresponding blood units had been released; all units reported after more than 7 days had already been issued for clinical use, with no adverse transfusion reactions reported upon follow-up. Conclusion: The confidential unit exclusion program has played an active role in establishing a supplementary information feedback channel for blood donors. The procedure can be optimized by strengthening interactive communication and confirmation before donation, improving the accuracy of donors' self-assessment, and expanding convenient and rapid information-based reporting channels.

Objective:To investigate the clinical efficacy of minimally invasive double anchoring combined with percutaneous kyphoplasty (PKP) for Kümmell disease.Methods:The clinical data of 24 patients with Kümmell disease who were treated with minimally invasive double anchoring combined with PKP in Cangzhou People's Hospital from October 2022 to March 2024 were retrospectively analyzed. Among them, there were 2 T 10 vertebrae, 5 T 11 vertebrae, 7 T 12 vertebrae, 6 L 1 vertebrae, and 4 L 2 vertebrae. There were 6 males and 18 females. The average age was 72.05±4.52 years (range, 66-80 years). The bone mineral density T value was -3.41±0.77 (range, -2.5-4.5). The stages of Li's Kümmell disease included 13 cases of stage II and 11 cases of stage III. The operation time, intraoperative blood loss, and volume of bone cement injected were recorded. The vertebral index, vertebral angle and Cobb angle of diseased segment were measured before and after operation. The visual analogue scale (VAS) was used to assess the degree of pain, the Oswestry disability index (ODI) and the Japanese Orthopaedic Association (JOA) low back pain scale were used to assess spinal function. The Medical Outcome Study short form 36 item health survey (SF-36) was used to assess the general health status of the patients. The postoperative symptom recovery was evaluated by Odom criteria. Results:The mean operative time of the 24 patients was 35.32±6.86 min, the injected volume of bone cement was 4.39±1.72 ml, and the intraoperative blood loss was 16.56±5.21 ml. All patients were followed up for 10 to 14 months, with an average of 11.7 months. Postoperative CT examination showed that the screw positions were satisfactory, and no loosening or displacement of bone cement mass occurred. On the first day after surgery, the vertebral body index, vertebral body angle and Cobb angle of diseased segment were 77.71%±2.75%, 12.40°±1.53° and 25.77°±4.49°, respectively, which represented significant improvements from the preoperative values of 43.09%±5.66%, 22.12°±2.92° and 46.98°±5.68° before surgery ( P<0.05). At the last follow-up, the values were 76.18%±2.32%, 12.41°±2.53°, 26.14°±4.87°, respectively, which were significantly improved compared with those before surgery ( P<0.05), but there was no statistical significance compared with the first day after surgery ( P>0.05). The VAS, ODI and JOA scores on the first day after surgery were 2.11±0.87 points, 22.46±5.49 points and 27.68±2.45 points, respectively, which were significantly improved compared with those before surgery 7.50±0.98 points, 76.25±8.56 points and 14.96±4.91 points ( P<0.05). At the last follow-up, the values were 2.26±0.88, 23.87±3.25 and 26.58±2.77, respectively, which were significantly improved compared with those before surgery ( P<0.05), and there was no statistical significance compared with the first day after surgery ( P>0.05). All 24 patients completed SF-36 scale assessment, and the results showed that there were statistically significant differences in physiological function, physiological role, physical pain, general health status, social function scores and mental health between the patients before surgery and the last follow-up ( P<0.05), while there were no statistically significant differences in vitality and emotional function ( P>0.05). At the last follow-up, the Odom criteria showed excellent results in 18 cases, good in 4 cases, and fair in 2 cases. Conclusions:The application of minimally invasive double anchoring (single nail fixation) combined with PKP in the treatment of Kümmell disease can effectively prevent the loosening and displacement of bone cement masses, and the fixation effect is satisfactory, which can restore the height of the injured vertebrum, reduce kyphosis and improve spinal function. The clinical symptoms of the patients were significantly improved, and the quality of life was enhanced.

Objective To re-evaluate systematic reviews on the application of virtual reality(VR)technology in limb rehabilitation for stroke patients,providing evidence to support the implementation of VR.Methods Systematic searches were conducted in Web of Science,PubMed,CINAHL,Cochrane Library,Embase,CNKI,CBM,WanFang,and VIP databases from their inception until March 2025,identifying systematic reviews/meta-analyses investigating VR for limb rehabilitation in stroke patients.2 researchers independently screened the literature.Methodological quality was evaluated using the Assessment of Mutiple System Reviews 2(AMSTAR 2)tool;reporting quality was evaluated according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA)guidelines;evidence quality was graded using the Grades of Recommendations Assessment,Development,and Evaluation(GRADE)system;literature overlap was assessed using the Corrected Covered Area(CCA)method.Results A total of 15 articles were included.According to AMSTAR 2,totally 3 reviews were of moderate quality,while the remainder were rated as low or very low quality.PRISMA scores ranged from 19.5 to 27.0 points.Based on GRADE,a review was classified as high quality,6 as moderate quality,and the remainder as low or very low quality.The CCA was 5.3％,indicating slight overlap.Conclusion VR contributes to the improvement of indicators such as upper limb motor function/mobility and lower limb balance in stroke patients.However,methodological limitations,including weak control of bias and inadequate handling of heterogeneity among included studies,restrict the overall quality of evidence.Further standardized,high-quality studies are needed to provide more reliable evidence to support clinical decision-making.

Objective:To summarize the clinical characteristics and treatment experience of patients with botulism after cosmetic botulinum toxin injection.Methods:A retrospective study was conducted on patients admitted to the Department of Medical Aesthetic and Plastic Surgery of the Fifth Affiliated Hospital of Zhengzhou University for botulism after cosmetic botulinum toxin injection between January 1, 2023, and October 31, 2024. Clinical data and treatment regimens were collected. Patients received botulinum antitoxin injection, neurotrophic therapy, nutrition supplementation, modulation and enhancement of cellular immune function, and systemic supportive care based on their condition. Prior to antitoxin administration, a skin test was performed. Patients with a negative test received intramuscular injections of 10 000 U of antitoxin serum every 12 hours, while those with a positive result underwent a desensitization protocol. The cessation criterion was significant improvement of toxic symptoms. Data collected included age, gender, region, time of presentation, injection location, brand and type of toxin, injection time, sites and dose of injection, time to onset of initial symptoms, main symptoms, skin test result for antitoxin, dosage of antitoxin administered, length of hospital stay, adverse reactions and prognosis. Data analysis was performed using GraphPad Prism Version 10.2.0.Results:A total of 179 patients were included, with 8 cases in 2023 and 171 cases in 2024. The majority were female (97.2%, 174 cases). The age range was 18-62 years, with a median age of 35 years; the highest proportion was in the 20-40 age group (71.5%, 128 cases). Patients were from 23 different provinces, autonomous regions, and municipalities directly under the central government in China. The injected product was mostly an unspecified brand of botulinum toxin (57.5%, 103 cases). Injections were primarily administered in non-medical institutions, with beauty salons or private studios accounting for 88.8% (159 cases). Injection sites included the platysma (92 cases), masseter muscle (82 cases), orbicularis oculi muscle (82 cases), frontalis muscle (67 cases), among others, with some patients receiving injections at multiple sites. 69 cases (38.5%) of patients were unaware of the injected dose; for the remaining cases, based on information provided, the injected doses were all within the safe range. The incubation period was mostly 1-7 days. The main symptoms included fatigue (171 cases), dysphagia (137 cases), dizziness (101 cases), blurred vision (76 cases), and difficulty opening eyes (66 cases). 176 patients received botulinum antitoxin treatment; 82 cases (46.6%) had a positive skin test and received desensitization injections, while 94 cases (53.4%) had a negative test. The total dosage of antitoxin used ranged from 10 000 U to 240 000 U. Three patients received only adjuvant therapy such as neurotrophic support. Adverse reactions during treatment primarily included induration at the injection site and serum sickness, all of which resolved after symptomatic treatment with antihistamines, steroids, etc. The hospital stay ranged from 1 to 24 d, with an average of 4.6 d. Upon discharge, symptoms in all patients had alleviated or resolved. At the 6-month follow-up after discharge, 14 patients were lost to follow-up; the remaining patients recovered well with no other complications.Conclusion:Poisoning incidents due to the illegal or improper use of botulinum toxin are increasing. Administration of botulinum antitoxin is an effective means to ameliorate intoxicating symptoms. Patients should seek timely medical intervention and receive antitoxin treatment as early as possible. Desensitization administration does not affect the efficacy of the antitoxin.

Objective To explore the role of secreted phosphoprotein 1(SPP1)and myeloid differentiation primary response 88(MYD88)in morphine-induced cardiomyocyte apoptosis.Methods A morphine addiction model was established in Sprague-Dawley(SD)rats.Twelve SD rats were randomly assigned to the normal saline(NS)group or the morphine-dependent(DAM)group.Histopathological analysis was employed to observe and compare myocardial tissue morphology between the two groups.Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling(TUNEL)staining was performed to assess the number of apoptotic cells in each group.The expression levels of SPP1 and MYD88 were evaluated using immunohistochemistry.Quantitative real-time poly merase chain reaction(RT-qPCR)and Western blot were used to detect the mRNA and protein expression of SPP1,MYD88,Bax,Bcl2,Caspase-3,and Caspase-9.Simultaneously,Western blot analysis was used to detected the expression of Cleaved Caspase-3 and Cleaved Caspase-9 proteins.In vitro,SPP1 expression was knocked down in primary neonatal rat cardiomyocytes(NRCMs),and cells were divided into three groups:control(CON),morphine treated(DA),and shSPP1#3+DA.Cell viability was assessed using the CCK-8 assay,and apoptosis rates were determined by flow cytometry.Results HE and TUNEL staining of myocardial tissues from morphine-addicted SD rats revealed that,compared with the NS group,myofibrils in the DAM group exhibited partial disruption and a significant increase in apoptotic cells(P<0.05).Western blot and RT-qPCR analyses demonstrated that,relative to the NS group,the mRNA and protein levels of SPP1,MYD88,Bax,Caspase-3,and Caspase-9 were significantly upregulated in the DAM group(P<0.05),whereas Bcl2 expression was significantly downregulated at both mRNA and protein levels(P<0.05),and the protein expression levels of Cleaved Caspase-3 and Cleaved Caspase-9 were also increased.with all differences being statistically significant.In NRCMs following morphine intervention,cell viability in the DA group was markedly reduced compared to the CON group(P<0.05),accompanied by a signifi-cant increase in apoptosis rate(P<0.05).Consistently,Western blot and RT-qPCR results showed elevated mRNA and protein expression of SPP1,MYD88,Bax,Caspase-3,and Caspase-9 in the DA group(P<0.05),along with decreased Bcl2 expression(P<0.05).The protein expression levels of Cleaved Caspase-3 and Cleaved Caspase-9 were elevated simultaneously.In contrast,the shSPP1#3+DA group exhibited opposing trends compared to the DA group,with statistically sig nificant differences(P<0.05).Conclusion SPP1 and MYD88 play critical roles in mediating morphine-induced cardiomyocyte apoptosis,and silencing SPP1 has been shown to significantly reduce the extent of cardiomyocyte apoptosis following morphine exposure.

Laparoscopic right hemicolectomy is the standard surgical procedure for treating right-sided colon cancer,yet its complex anatomical layers and technically demanding operations pose significant challenges to surgeons'expertise.Currently,surgical skill assessment in clinical practice still predominantly relies on subjective expert evaluation,an approach inherently limited by low efficiency and inconsistent standards.With the rapid advancement of artificial intelligence(AI)technologies(particularly breakthroughs in computer vision and deep learning algorithms),a revolutionary technical foundation has been established for developing objective and precise automated surgical evaluation systems.This article comprehensively reviewed the current clinical application status of right hemicolectomy in China,thoroughly examined the clinical necessity and technical feasibility of constructing an intelligent surgical assessment system,and systematically presented our center's cutting-edge research achievements in this field.Looking ahead,AI-driven intelligent evaluation systems are expected to standardize and quantify surgical skill assessment.Such innovation will not only transform surgical training programs and enhance the quality of multicenter clinical research,but also promote the standardization of precision surgical protocols.This advancement holds significant clinical value and societal importance by improving long-term patient outcomes and fostering more equitable distribution of medical resources.
