Objective To investigate the correlation between serum insulin like growth factor 1 receptor(IGF1R)and epidermal growth factor-like domain-containing protein 7(EGFL7)levels and the condition and pregnancy outcome of patients with preeclampsia(PE).Methods A total of 120 PE patients admitted to the hospital from January 2021 to January 2024(PE group)and 60 healthy pregnant women during the same peri-od(control group)were selected.The PE patients were divided into severe PE group(68 cases)and mild PE group(52 cases)according to their conditions,and divided into poor group(62 cases)and good group(68 ca-ses)according to the pregnancy outcome.Enzyme-linked immunosorbent assay was used to detect serum IGF1R,EGFL7 levels.Using the pregnancy outcome of PE patients as the dependent variable,multivariate un-conditional Logistic regression was used to determine the influencing factors of their pregnancy outcomes,and receiver operating characteristic curve was used to evaluate the predictive value of serum IGF1R and EGFL7 levels.Results Compared with the control group,serum IGF1R levels were reduced and EGFL7 levels were increased in the PE group(t=-16.908,16.234,P＜0.001).Serum IGF1R levels were decreased and EGFL7 levels were increased in the severe PE group compared with the mild PE group(t=-5.317,5.305,P＜0.001).The incidence of adverse pregnancy outcomes in PE patients was 51.67％(62/120).The independent risk factors for adverse pregnancy outcomes in patients with PE were severe PE(OR=3.906,95％CI:1.305-11.689),elevated 24-h urinary protein(OR=2.030,95％CI:1.290-3.194),elevated EGFL7(OR=1.116,95％CI:1.040-1.198),and the independent protective factor was elevated IGF1R(OR=0.908,95％CI:0.865-0.954,P＜0.05).The area under the curve for serum IGF1R and EGFL7 levels alone and in com-bination to predict adverse pregnancy outcomes in PE patients was 0.791(95％CI:0.707-0.860),0.784(95％CI:0.700-0.854),and 0.866(95％CI:0.781-0.911),and serum IGF1R and EGFL7 levels were grea-ter jointly(Z=2.456,2.244,P＜0.05).Conclusion Decreased serum IGF1R levels and increased EGFL7 levels are associated with exacerbation and adverse pregnancy outcomes in patients with PE,and the combina-tion of serum IGF1R and EGFL7 levels is of high value in predicting adverse pregnancy outcomes in patients with PE.

Objective To explore the effect of management model of clinical pharmacists participating in multidisciplinary collaborative diagnosis and treatment(MDT)for new anti-tumor drugs in the national medical insurance drug negotiation(hereinafter referred to as"national negotiation"),including efficacy,safe-ty,economy and rationality.Methods The medical records of 326 cases using novel anti-tumor drugs by na-tional negotiation and conforming to the including and excluding standards in this hospital from July 2018 to June 2023 were retrospectively analyzed.The patients were divided into the MDT group(n=122)and non-MDT group(n=204).The patients diagnosed as non-small cell lung cancer(NSCLC)in the two groups were extracted and defined as the MDT-NSCLC subgroup(n=41)and non-MDT-NSCLC subgroup(n=77).The progression-free survival(PFS),overall survival(OS),disease control rate(DCR)and the indexes such as survival quality and medical quality control were compared between the groups.Results The median PFS in the two groups was 12.7 months and 8.0 months,the median OS was 75.2 months and 56.3 months,DCR was 96.72％and 81.86％respectively,and the differences were statistically significant(P＜0.05).The COX multivariate regression analysis indicated that the HR value of clinical pharmacists participating in MDT was higher than the other influencing factors.The median PFS time in the MDT-NSCLC subgroup and non-MDT-NSCLC subgroup was 10.5 months and 6.7 months,DCR was 97.30％and 75.64％respectively,and the differences were statistically significant(P＜0.05),the median OS time was 55.1 months and 40.3 months respectively,and the difference was statistically significant(P＞0.05).The COX multivariate regression anal-ysis indicated that the HR value with clinical pharmacists participating in MDT was higher than the other in-fluencing factors;The adverse reaction occurrence rate in the MDT group and non-MDT group was 45.9％and 58.3％respectively,and the difference was statistically significant(P＜0.05).The KPS score after treatment in the MDT group was higher than that in the non-MDT group,and the difference was statistically significant;in the aspect of medical quality control,the average drug proportion in the MDT group and non-MDT group was 63.93％and 64.54％respectively,the rational drug rate of comments on prescription was 98.36％and 88.73％respectively,the patient satisfaction average value was 90.69 points and 87.36 points respectively and the differences were statistically significant(P＜0.05).Conclusion Clinical pharmacists participating in MDT related to novel anti-tumor drugs by national negotiation is beneficial to improve the therapeutic effects,living quality and patient satisfaction,also benefit to management and control of off-label drug use and medical quality control indexes.

Antibody-drug conjugates (ADCs) represent a promising class of targeted cancer therapeutics that combine the specificity of monoclonal antibodies with the potency of cytotoxic payloads. Despite their therapeutic potential, the use of ADCs faces significant challenges, including off/on-target toxicity and resistance development. This review examines the current landscape of ADC development, focusing on the critical aspects of target selection and antibody engineering. We discuss strategies to increase ADC efficacy and safety, including multitarget approaches, pH-dependent antibodies, and masked peptide technologies. The importance of comprehensive antigen expression profiling in both tumor and normal tissues is emphasized, highlighting the role of advanced technologies, such as single-cell sequencing and artificial intelligence, in optimizing target selection. Furthermore, we explore combination therapies and innovations in linker‒payload chemistry, which may provide approaches for expanding the therapeutic window of ADCs. These advances pave the way for the development of more precise and effective cancer treatments, potentially extending ADC applications beyond oncology.

OBJECTIVES: To explore the relationship between white matter injury (WMI) and cerebral perfusion in preterm infants using arterial spin labeling (ASL). METHODS: A total of 293 preterm infants (gestational age <34 weeks) hospitalized at the Third Affiliated Hospital of Zhengzhou University between June 2022 and June 2024 were included. After achieving clinical stability, the infants underwent brain magnetic resonance imaging (MRI) and ASL. Based on MRI findings, infants were classified into WMI (n=66) and non-WMI (n=227) groups. Cerebral perfusion parameters were compared between groups, and the association between WMI and perfusion alterations was evaluated. RESULTS: The WMI group showed a higher incidence of mild intraventricular hemorrhage (IVH) than the non-WMI group (P<0.05). Significantly lower cerebral perfusion was observed in the WMI group across bilateral frontal, temporal, parietal, and occipital lobes, as well as the basal ganglia and thalamus (P<0.05). After adjusting for gestational age, corrected gestational age at ASL scan, and mild IVH, WMI remained significantly associated with reduced regional perfusion (P<0.05). CONCLUSIONS WMI in preterm infants correlates with localized cerebral hypoperfusion. ASL-detected perfusion abnormalities may provide novel insights into WMI pathogenesis.

Objective:To observe the characteristics of brain functional activity in patients with chronic non-specific low back pain(CNLBP)and to explore the potential mechanism of brain functional remodeling in acupuncture treatment based on resting-state fMRI.Method:The 22 patients with CNLBP were included as the CNLBP group,and 22 healthy subjects(HCs)were included as the HCs group.The visual analogue scale(VAS)for pain,Oswestry disability index(ODI),Japanese Orthopedic Association(JOA)score for lumbar spine were collected before and after acu-puncture treatment in the CNLBP group.Resting-state fMRI data were acquired for all participants.The frac-tional amplitude of low frequency fluctuation(fALFF)values of the different brain regions in CNLBP patients before treatment compared with the HCs group were extracted and correlated with the differences in VAS,ODI,and JOA scores.Result:Acupuncture treatment significantly improved the VAS,ODI,and JOA scores in the CNLBP group(P＜0.001);Before treatment,the CNLBP group showed higher fALFF values in the right orbital middle frontal gy-rus,right anterior cingulate gyrus,left anterior cingulate gyrus and left precuneus compared to the HCs group,while lower fALFF values were observed in the right precentral gyrus/right postcentral gyrus,left precentral gy-rus/left postcentral gyrus,right thalamus,right postcentral gyrus/precentral gyrus,and left thalamus.After treat-ment,the CNLBP group exhibited increased fALFF values in the right precentral gyrus/postcentral gyrus,left precentral gyrus/postcentral gyrus,and left middle temporal gyrus,and decreased fALFF values in the left me-dial superior frontal gyrus,right precuneus/left precuneus compared to pre-treatment.Additionally,pre-treatment fALFF value in the right orbital part of the middle frontal gyrus,right anterior cingulate gyrus and left anteri-or cingulate gyrus in the CNLBP group was negatively correlated with the changes in VAS scores(r=-0.699,P=0.000).Conclusion:Acupuncture treatment can significantly improve pain intensity and lumbar spinal dysfunction in CNLBP.CNLBP has multiple abnormalities in brain functional activities related to pain regulation pathways and the default mode network(DMN),and acupuncture treatment can restore most of these abnormal brain ac-tivities;the characteristic of brain functional activity in the right orbital part of the middle frontal gyrus,right anterior cingulate gyrus and left anterior cingulate gyrus before CNLBP treatment is related to the difference in VAS score,providing a potential imaging biomarker for predicting treatment efficacy.

Objective:To investigate the effects of moxibustion,filiform needle acupuncture,and electroacupuncture on synovial hypoxia and expression of synovial fibrosis markers[transforming growth factor(TGF)-β and collagen alpha-1(Ⅰ)chain(COL1A1)]in knee osteoarthritis(KOA)rats.Methods:Fifty Sprague-Dawley rats were randomly divided into a normal group,a model group,a moxibustion group,an acupuncture group,and an electroacupuncture group,with 10 rats in each group.Except for the normal group,rats in the other four groups were injected with sodium iodoacetate into the right knee joint cavity to establish KOA models.The right Futu(ST32)and Zusanli(ST36)were selected in the moxibustion,acupuncture,and electroacupuncture groups to perform the mild moxibustion with moxa sticks,filiform needle acupuncture,or electroacupuncture,respectively.Each intervention lasted 15 min,once every other day,and continued for 4 weeks,with a total of 14 interventions.The Lequesne score was used to evaluate the degree of knee dysfunction before and after intervention,and the rat's right knee joint diameter was measured to evaluate the degree of knee swelling.Morphological changes of the right knee joint synovial tissue were observed using hematoxylin-eosin staining.Hypoxia probe immunofluorescence staining was used to observe the degree of synovial hypoxia in rats.Western blotting was used to detect the protein expression levels of hypoxia-inducible factor(HIF)-1α,TGF-β,and COL1A1 in the synovial tissue of the right knee joints.Results:Before intervention,the Lequesne score and the right knee joint diameter in the other four groups increased significantly compared to the normal group(P<0.01).After intervention,the Lequesne score and the right knee joint diameter increased significantly in the model group compared to the normal group(P<0.01)together with worsened cartilage deformation and osteophytes,inflammatory cell infiltration and fibrosis in synovial tissue,and hypoxia degree,and the expression levels of HIF-1α,TGF-β,and COL1A1 proteins in the knee joint synovial tissue of rats increased(P<0.01).The Lequesne score and the right knee joint diameter decreased significantly(P<0.01 or P<0.05),the cartilage morphology was normal without obvious osteophytes,and the hypoxia degree reduced in the three intervention groups compared to the model group.Among them,the moxibustion group had the most notable improvement in hypoxia,synovial tissue fibrosis,angiogenesis,and inflammatory cell infiltration.The expression levels of HIF-1α,TGF-β,and COL1A1 proteins decreased in the moxibustion and electroacupuncture groups(P<0.01),and the expression levels of HIF-1α and TGF-β proteins were decreased in the acupuncture group(P<0.01).Conclusion:Moxibustion,filiform needle acupuncture,and electroacupuncture improve knee joint function and reduce knee joint swelling in KOA rats.The mechanism may be to improve synovial fibrosis of the knee joint by regulating HIF-1α;moxibustion has the best effect on improving hypoxia among the three interventions,but the effect of filiform needle acupuncture on COL1A1 is not significant.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To introduce the concepts and principles of the win ratio method and to analyze it in the context of a case study of a clinical trial in cerebrovascular disease.Methods Based on the study of clopidogrel with aspirin in high risk patients with acute non disabling cerebrovascular events 2,and key prognostic factors,the outcome events were defined sequentially as ① time to death within 90 d,② time to recurrence of ischemic stroke within 90 d,③ time to moderate-to-severe hemorrhage within 90 d.Using clopidogrel combined with aspirin as the reference group,the winning ratio(Rw)of ticagrelor combined with aspirin was analyzed by the win ratio method,and the 95% confidence interval(CI)of Rw was estimated by the Bootstrap method and compared with the hazard ratio(HR)calculated by the competing risk model.Results When only fatal events were considered,the win ratio method suggested that the ticagrelor group was significantly better than the clopidogrel group,Rw=2.00(95% CI:1.52-2.47),and after stepwise inclusion of ischemic stroke and moderate-to-severe hemorrhage recurrence,the win ratio method yielded a value of 1.29(95% CI:1.25-1.57),and the HR value from Fine and Gray competing risk regression was 0.78(95% CI:0.65-0.95),both of which indicated that the efficacy of the ticagrelor group was superior to that of the clopidogrel group.Conclusion The win ratio method can be used to analyze clinical trials with composite endpoints after prioritizing multiple outcome variables,showing the advantages of win ratio and its promising application in cerebrovascular disease research.
