To provide in-service medical technicians and nurses with convenient access to continuing education resources in transfusion medicine, reduce transfusion-related adverse events, and ensure the safety, rationalization, and effectiveness of clinical transfusion, we designed and developed an online transfusion continuing education platform. The platform was based on the new managed code programming model.NET Core and the powerful functions of hypertext preprocessor PHP 7.4, addressing current issues in transfusion online continuing education. Through in-depth analysis of student attributes, learning behaviors, and teaching behaviors, a comprehensive online continuous teaching quality evaluation index system was established. This system not only facilitates the quantitative assessment of teaching quality but also successfully integrates the two core functions of teaching and management, thereby achieving unified online teaching.

Objective To analyze the epidemiological characteristics of human papillomavirus(HPV)infection in women in the Zhongguancun area of Beijing,and to evaluate the infection rates and genotype distribution between different populations and age groups.Methods A retrospective analysis was conducted on HPV genotyping results of 13,105 women who visited the gynecology outpatient department or underwent routine health check-ups at Zhongguancun Hospital from March 2019 to April 2024.High-risk HPV genotypes(15 types)were detected using a fluorescence PCR assay.Positive cases were classified as single,dual or multiple(≥3)infections based on the number of genotypes.Subjects were stratified into six age groups(≤30,31-40,41-50,51-60,61-70,and≥71 years),and the characteristics of infection by type and age group were analyzed.Results The overall HPV positivity rate was 10.78%(1,413/13,105),with a significantly higher rate in the outpatient group than that in the health check-up group(16.36%vs.6.06%,P<0.01).The three most prevalent genotypes were HPV52(18.83%),HPV58(13.85%),and HPV16(11.28%).Single infections accounted for 79.19%of cases,dual infections for 15.93%and multiple infections for 4.88%.Age distribution showed a U-shaped pattern,with higher infection rate in women aged≤30 years(15.06%)and 61-70 years(13.19%),and the lowest rate in the≥71 years(8.09%).Notably,women aged≤30 years had the highest proportion of multiple infections(31.72%).Conclusion These findings provide a basis for cervical cancer screening strategies,HPV vaccination promotion and individualized prevention of cervical cancer in this region.

Objective:To investigate the differences of comprehensively curative effect of neuro navigation system(NNS)-guided minimally invasive puncture(MIP)and conventional craniotomy hematoma evacuation(CHE)in treatment for traumatic intracerebral hemorrhage,and analyze the mechanisms of affecting the differences of the trajectories postoperative neurologically functional recovery between two kinds of surgical methods.Methods:Based on the design of multicenter prospective cohort study,a total of 240 patients with traumatic intracerebral parenchymal hemorrhage,who admitted to the Neurosurgery Center of Rugao Hospital of Traditional Chinese Medicine between June 2021 and May 2024,were selected.They were randomized into the NNS group(n=120)and the CHE group(n=120)by using a stratified block randomization method.The NNS group underwent NNS-guided surgical intervention,while the CHE group received conventional craniotomy.The primary endpoint was hematoma evacuation rate at the postoperative 7th day.The secondary endpoints encompassed surgical parameters,complications,and the prognostic indicators of function.Microstructural assessment was performed by using three-dimensional image fusion technique[three-dimensional-T1weighted imaging magnetic resonance imaging(3D-T1WI MRI)combined with thin-slice computed tomography(CT)]and tract-based spatial statistics(TBSS).Results:At the dimension of hematoma evacuation,the average hematoma evacuation rate of NNS group was(88.37±6.52)%at the postoperative 7th day,which was significantly higher than(76.15±10.32)%of CHE group,and the residual hematoma volume of NNS group was(5.23±2.15)mL at the postoperative 7th day,which was less than(11.49±4.78)ml,and the differences of them between two groups were significant(t=9.843,7.015,P<0.05),respectively.The surgical trauma parameters appeared polarization:the mean incision length in the NNS group was(3.15±0.73)cm,which reduced 76.3%of(13.24±2.15)cm of the CHE group,with statistically significant difference(Z=15.327,P<0.05).The operative duration of NNS group was(68.34±15.32)min,which was shorter than(142.56±23.48)min,and the difference was significant(t=29.846,P<0.05).The radiation dose of NNS group was(312.45±85.32)cGy·cm2,which was significantly higher than(45.23±12.15)cGy·cm2 of CHE group,and the difference was significant(Z=24.156,P<0.05).The volume of intraoperative blood transfusion of NNS group was(50.34±25.36)ml,which was significantly less than(325.67±158.32)ml,and the difference was significant(Z=18.943,P<0.05),The result of complication genealogy analysis indicated that the re-bleeding incidence of the NNS group was 6.67%,which decreased by 9.16%than 15.83%of the CHE group,and the difference of that between two groups was statistical significance(x2=5.627,P<0.05).However,there was not significant difference in infection rates and incidences of deep vein thrombosis between the two groups(P>0.05).For functional recovery,the proportion of patients whose modified Rankin Scale(mRS)scores was≤2 at the postoperative 90th day was 52.50%in the NNS group,which increased 13.33%than 39.17%in the CHE group,and the difference of that between two groups was statistical significance(x2=4.302,P<0.05).Additionally,the improvement value of National Institutes of Health Stroke Scale(NIHSS)was(9.34±4.156)in the NNS group,which existed marginal advantage of 2.19 points than(7.15±5.327)of the CHE group,and the difference was significant between two groups(Z=3.842,P<0.05).Conclusion:NNS-guided MIP appears notable advantages in enhancing hematoma evacuation efficiency and improving prognosis of neurological function.However,its increased amount of radiation exposure,and risks of specific complication should be considered.The craniotomy approach remains indispensable for complex hematoma morphologies.

Aim To investigate the role and mecha-nism of allopurinol(ALLO)in restoring the abnormal metabolism of kynurenine(Kyn)mediated by trypto-phan-2,3-dioxygenase 2(TDO2)to ameliorate ulcera-tive colitis(UC)in mice,and to provide experimental basis for the treatment of UC by ALLO.Methods A dextran sodium sulfate(DSS)-induced mouse UC mod-el was established,and the mice were randomly divided into the control group,the model group,the ALLO low,medium and high-dose groups(10,20,and 40 mg·kg-1),and the positive-significant salazosulfapyridine(SASP)(200 mg·kg-1)group.The body mass and disease activity index(DAI)scores of mice were re-corded;HE staining was performed to observe the de-gree of pathological damage in colon tissue;Western blot was performed to detect TDO2 protein expression in colon tissue;flow cytometry was performed to detect changes in the proportion of macrophages in spleen and mesenteric lymph nodes;ELISA was employed to de-tect the levels of TNF-α,IL-1β and IL-6 pro-inflamma-tory cytokines in the supernatant of colon tissue homog-enate;high performance liquid chromatography(HPLC)was used to detect the levels of tryptophan(Trp)and Kyn in the supernatant of colon tissue ho-mogenate.Results Compared with the model group,ALLO administration significantly ameliorated colonic histopathological injury in UC mice,decreased the pro-portion of macrophages in spleen and mesenteric lymph nodes,down-regulated the levels of TNF-α,IL-1 β,and IL-6 pro-inflammatory factors in serum of homogenate of colonic tissues,and inhibited the activity(Kyn/Trp ratio)and expression of TDO2 in colonic tissues.Con-clusion ALLO improves disease manifestations in mice with ulcerative colitis,which may be related to its restoration of abnormal Kyn metabolism.

Objective To explore the role of SLIT-ROBO Rho GTPase-activating protein 2(srGAP2)in spinal motor neuron degeneration in amyotrophic lateral sclerosis(ALS).Methods Applied bioinformatics analysis to investigate the expression changes of srGAP2 in the spinal cord of human superoxide dismutase 1(hSOD1)mutant ALS transgenic mice.hSOD1 G93A mutant ALS transgenic mice were selected for animal experimental validation,with littermate wild type(WT)mice serving as the control group.A total of 36 pairs were divided into four groups,namely the pre-onset stage,early-onset stage,mid-onset stage,and late-onset stage.The expression changes and cellular localization of srGAP2 in the spinal cord of ALS mice were detected by Real-time PCR,Western blotting and immunofluorescent double-label staining.The hSOD1G93A mutant NSC34 motor neuron-like cell model was established,and in vitro experiments were carried out to detect the changes in srGAP2 expression,and the effects of srGAP2 over-expression on the viability of hSOD1G93A mutant NSC34 cells and the growth of cell protrusions.Results Bioinformatics analysis revealed abnormally low expression of srGAP2 in the spinal cord of hSOD1 mutant ALS mice.Animal experiments verified that compared with the WT mice,the expression of srGAP2 was reduced at both mRNA level and protein level in the spinal cord of hSOD1G93A mutant ALS transgenic mice at early-onset,mid-onset and late-onset stages.Compared with the WT mice,srGAP2 integral absorbance(IA)values in srGAP2+/NeuN+double-positive cells in the anterior horn of the spinal cord of hSOD1G93A mutant ALS transgenic mice were lower,srGAP2 IA values in srGAP2+/GFAP+double-positive cells were higher;Compared with the hSOD1WT NSC34 cells,the expression of srGAP2 was reduced at both mRNA level and protein level in hSOD1G93A mutant NSC34 cells.Over-expression of srGAP2 elevated the viability of hSOD1G93A mutant NSC34 cells,and up-regulated the expression level of synapse-related protein β Ⅲ-tubulin and growth associated protein 43(GAP43).Conclusion Low expression of srGAP2 is closely associated with the progression of ALS,while over-expression of srGAP2 can promote outgrowth of cell protrusions and exert a protective effect on spinal motor neurons in ALS.

Objective:To investigate the diagnostic and prognostic value of systemic immune inflammatory index (SII) for severe traumatic brain injury secondary to acute lung injury (sTBI-ALI).Methods:A retrospective study was conducted on patients with severe traumatic brain injury admitted to the trauma center of the First Affiliated Hospital of Soochow University from January 2021 to November 2023. Patients received standard treatments including hemostasis and intracranial pressure management. Vital signs and blood routine data were collected upon admission. Patients were categorized into sTBI group and sTBI-ALI group based on established clinical diagnostic criteria for ALI to evaluate the diagnostic utility of SII. Subsequently, within the sTBI-ALI group, patients were stratified into survival and non-survival groups based on their 30-day outcomes to assess the prognostic value of SII.Results:A total of 260 sTBI patients were enrolled, of whom 113 developed ALI. Among the sTBI-ALI patients, 73 survived at 30 days. Compared to the sTBI group, the sTBI-ALI group exhibited significantly higher respiratory rates, heart rates, white blood cell counts, neutrophil counts, platelet counts, and SII levels (all P<0.05). Multivariate logistic regression analysis showed that SII index ( OR=1.003, 95% CI: 1.002-1.004, P<0.001) was an independent risk factor for ALI development in sTBI patients. The combined predictive model incorporating SII and heart rate yielded an AUC of 0.801 (95% CI: 0.740-0.862). The non-survival group had significantly higher neutrophil counts and SII levels, and significantly lower Glasgow Coma Scale scores than the survival group (all P<0.05). Multifactorial regression analysis indicated that SII index ( OR=1.002, P=0.004, 95% CI: 1.000-1.003) served as an independent risk factor for 30-day mortality in sTBI-ALI patients. The combined predictive model of SII and GCS achieved an AUC of 0.904 (95% CI: 0.848-0.960). Conclusions:SII demonstrates potential as a biomarker for predicting the development of ALI following sTBI. Furthermore, incorporating SII into predictive models significantly enhances the ability to forecast mortality risk in sTBI-ALI patients.
