AIM: To compare objective visual quality and vision-related quality of life after implantation of different presbyopia-correcting intraocular lenses(PC-IOLs).METHODS:A prospective, non-randomized controlled study. Cataract patients who underwent phacoemulsification combined with PC-IOL implantation at Jinan Mingshui Eye Hospital from September 2023 and December 2025 were included. These patients were divided into three groups according to the type of IOL: the Trifocal IOL group,the Vivity group, and the Synergy group. Follow-ups were conducted at 1 wk,1 and 3 mo postoperatively. Uncorrected distance visual acuity(UDVA), uncorrected intermediate visual acuity(UIVA), and uncorrected near visual acuity(UNVA), objective scatter index(OSI), modulation transfer function cut off(MTF-cut off), and Strehl ratio(SR), as well as contrast visual acuity(CVA)at 100%, 20%, and 9% contrast were assessed. Postoperative defocus curves were plotted. Vision-related quality of life and spectacle independence were evaluated using questionnaires.RESULTS: This study included 101 cataract patients(101 eyes),aged 30-70(53.8±9.7)y,with 59 males and 42 females.The Trifocal group consisted of 33 patients(33 eyes), aged 30-71(51.7±11.3)y, with 21 males and 12 females; the Vivity group consisted of 37 patients(37 eyes), aged 36-71(54.2±9.0)y, with 18 males and 19 females; and the Synergy group consisted of 31 patients(31 eyes), aged 30-73(55.9±8.5)y, with 20 males and 11 females.No significant differences were observed among the three groups in UDVA or UIVA(all P>0.05). Significant differences were found in UNVA among groups(P<0.05). UDVA differed significantly across different time points(P<0.05), while there were no significant differences in UIVA and UNVA(all P>0.05). At 3 mo postoperatively, significant differences were found among the three groups in OSI, MTF -cut off, SR, and CVA at all contrast levels(all P<0.05). The defocus curve at postoperative 1 mo showed that the Trifocal group had a smooth and continuous profile from +1.0 D to -3.0 D, providing good distance, intermediate, and near vision. All groups demonstrated smooth transitions in the intermediate range(-1.0 D to -1.5 D), with LogMAR visual acuity better than 0.2. In the near range(-2.5 D to -3.5 D), the Trifocal and Synergy groups performed significantly better than the Vivity group. No significant differences were observed in VF-14 questionnaire scores among groups(P>0.05). For night driving(motorized or non-motorized), the Vivity group performed better than the Trifocal and Synergy groups. Spectacle independence rates were 92.3% in the Trifocal group, 54.1% in the Vivity group, and 80.0% in the Synergy group(P<0.05).CONCLUSION: All types of PC-IOLs can effectively improve postoperative full-range visual acuity in cataract patients. There are discrepancies in the objective visual quality between Trifocal IOLs and extended depth of focus(EDOF)IOLs. Some patients suffer from postoperative optical disturbances, which result in certain difficulties with night driving, although patients generally report favorable subjective visual perceptions.

Objective: To construct prediction models of female stress urinary incontinence (SUI), and evaluate the efficacy of each model, so as to provide reference for the early diagnosis of SUI. Methods: Female SUI patients treated in our hospital during Oct. 2019 and Oct. 2023 and healthy women undergoing physical examination during the same period were involved. Women 42 days after delivery were included in the postpartum group (n=611), and perimenopausal and postmenopausal women were included in the non-postpartum group (n=409). The number of random seeds was set and the participants were divided into the training and verification sets in a ratio of 7∶3. Relevant clinical data were collected, and meaningful variables were screened using single factor and Lasso regression, which were then incorporated into the K-nearest neighbor method (KNN), support vector machine (SVM)，decision tree (DT) and random forest (RF) algorithms. The sensitivity, specificity, accuracy and area under the receiver operating characteristic curve (AUC) of the models were calculated to screen out the optimal model. Results: There were 352 SUI patients (57.6%) in the postpartum group. According to single factor and Lasso regression, significant variables included age, body mass index (BMI), maximum rapid muscle stage, parity, bladder neck mobility (BND), urethral rotation angle (URA), lateral perineal incision, past incontinence, and constipation. In the verification set, the AUC of KNN，SVM，DT and RF models were 0.881，0.878，0.750 and 0.905,respectively; the AUC, accuracy, F1 index and Kappa value of RF model were the largest. In the non-postpartum group, there were 260 SUI patients, accounting for 63.6%. The significant variables were age，BMI, maximum value and recovery time of fast muscle stage, mean value of slow muscle stage, post-resting stage variability, vaginal delivery, past incontinence, and constipation. In the verification set, the AUC of KNN,SVM，DT and RF models were 0.819,0.805，0.603 and 0.830, respectively; the AUC, accuracy, Kappa value of the RF model were the largest. Conclusion: This study successfully established 4 prediction models for the incidence of SUI in women at 42 days postpartum, perimenopausal and postmenopausal women based on machine learning. Among them, the model adopting the RF algorithm had the best prediction efficiency.

Objective To explore the application value of intravoxel incoherent motion(IVIM)imaging parameters in the differential diagnosis of benign and malignant breast nodules and their correlation with the expression of Ki-67 receptor in breast cancer.Methods The data of 41 female patients who completed 3.0 T breast magnetic resonance imaging(MRI)with complete surgical pathology results in the Second Hospital of Jiaxing City from October 2022 to January 2025 were analysed and evaluated.Conventional images and diffusion-weighted images with 11 b values were collected.The IVIM imaging parameters of real diffusion coefficient(D),perfusion related diffusion coefficient(D*)and perfusion fraction(f)were measured and calculated in the region of interest of each lesion.The receiver operating characteristic curve were plotted to quantify the differential diagnostic efficacy of each parameter of IVIM imaging in benign and malignant breast nodules.The differences of parameters between benign and malignant breast nodules and between the groups with different expression levels of Ki-67 receptor in breast cancer were analysed,and the correlation between each parameter and the expression level of Ki-67 in breast cancer was counted.Results The D value of benign breast nodules group(benign groups)was significantly higher than that of malignant breast nodules group(malignant groups),and the D*value was significantly lower than that of malignant group,and the differences between benign group and malignant group were statistically significant(t=-4.773,t=2.063,P＜0.05);Thefvalue of benign group was slightly lower than that of malignant group,and the differences between two groups were not statistically significant(t=0.035,P＞0.05).Among the parameters of IVIM imaging,D value had the best differential diagnostic efficacy for benign and malignant breast nodules,with area under the curve(AUC)of 0.870(95％CI:0.755-0.985)and a specificity of 75.0％;D*value had the second best differential diagnostic efficacy after D value,with an AUC of 0.789(95％CI:0.658-0.920),but it had the highest sensitivity of 88.2％;And the differential diagnosis efficiency off value was the worst,much less than D and D*values.The D value in the high Ki-67 expression group of breast cancer was lower than that in the low expression group,while the D* and f values in the high expression group were higher than that in the low expression group,and the differences of each imaging parameter of IVIM were not statistically significant between two groups(t=-2.617,t=2.169,t=0.647,P＞0.05).There was a significant negative correlation between the expression of the Ki-67 receptor and the D value(r=-0.615,P＜0.05),and no significant correlation was seen with either D *or f value(r=0.223,r-0.031,P＞0.05).Conclusion The D and D*values of IVIM imaging parameters have great clinical value in the differential diagnosis of benign and malignant breast nodules.

The incidence of food allergy is on the rise, with the capacity to impact various organ systems, including but not limited to the skin, respiratory system, gastrointestinal system, cardiovascular system, and nervous system.In extreme cases, these allergies can result in anaphylaxis.Immunoglobulin E (IgE)-mediated type Ⅰ hypersensitivity reactions are a common cause of food allergy and are the primary pathway to anaphylaxis.Omalizumab, the first biologic therapy approved for the treatment of IgE-mediated food allergy, can be incorporated into a comprehensive management strategy for food allergy sufferers.However, due to the lack of definitive evidence, the safety and efficacy of Omalizumab in all patients with IgE-mediated food allergy remain equivocal.In light of this, Global Allergy and Asthma European Network Anaphylaxis Centres of Reference and Excellence convened a panel of experts to deliberate on the appropriate patient and therapeutic strategies for Omalizumab, culminating in a consensus statement.This paper aimed to interpret the consensus proposed by the experts, with the objective of assisting clinicians in better understanding the application of Omazumab in patients with IgE-mediated food allergy.

Purpose To explore the relationship between semi-quantitative parameters maximum standard uptake value(SUVmax)and target-background ratio(TBR)of 18F-FDG PET/CT imaging and the activity of Takayasu arteritis.Materials and Methods A total of 110 patients with Takayasu arteritis from February 2016 to December 2022 in the First Affiliated Hospital of Zhengzhou University who underwent 18F-FDG PET/CT images were retrospectively reviewed.All Takayasu arteritis patients were divided into active(92 cases)and inactive groups(18 cases)according to Kerr score.The region of interest technique was used to measure the SUVmax of the arterial wall,and compares the SUVmax with the average SUV in the center of the inferior vena cava and the maximum SUV measured in the right lobe of the liver to obtain TBRblood pool and TBRliver.The diagnostic efficacy of SUVmax,TBRblood pool and TBRliver in Takayasu arteritis activity was compared using the receiver operating characteristic curve.The relationship between PET/CT parameters and Kerr score,erythrocyte sedimentation rate and C-reactive protein was evaluated.Results SUVmax,TBRblood pool and TBRliver in the active group were higher than those in the inactive group[3.70(3.03,5.18)vs.1.45(1.38,1.53),2.50(1.93,3.88)vs.0.91(0.79,1.16)and 1.37(1.00,1.96)vs.0.44(0.39,0.63);Z=5.510-5.900,all P<0.001],respectively.A SUVmax level of 2.65 was shown to be the best predictive cut-off value for Takayasu arteritis disease activity(sensitivity 83.7%,specificity 100%and area under the curve 0.91).A TBRblood pool level of 1.63 was shown to be the best predictive cut-off value for Takayasu arteritis disease activity(sensitivity 83.7%,specificity 94.4%and area under the curve 0.93).A TBRliver level of 0.81 was shown to be the best predictive cut-off value for Takayasu arteritis disease activity(sensitivity 87.0%,specificity 100%and area under the curve 0.94).SUVmax,TBRblood pool,TBRliver were all positively correlated with the Kerr score(r=0.88,0.89.0.90,all P<0.001),among which the correlation coefficient between TBRliver and the Kerr score was the highest.Conclusion SUVmax,TBRblood pool and TBRliver can evaluate disease activity in Takayasu arteritis patients,with TBRliver being the best.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

Objective:To investigate the dynamic characteristics of human papillomavirus (HPV) genomic integration during cervical lesion progression and the clinical value of HPV integration detection in stratify HPV-positive women, and to explore its molecular mechanisms in cervical carcinogenesis.Methods:A prospective cohort study was designed to enroll high-risk HPV (HR-HPV) positive women who underwent cervical cancer screening in Drum Tower Hospital Affiliated to Nanjing University Medical School and Nanjing Maternity and Child Health Care Hospital from July 2022 to July 2024. Cervical exfoliated cells samples were collected, and HPV whole genome targeted capture and high-throughput sequencing technology were used. The HPV integration patterns, host gene functional region distribution and pathway enrichment characteristics of 157 samples with different cervical lesions grades were analyzed, including 31 cases of normal cervix, 40 cases of cervical intraepithelial neoplasia (CIN) Ⅰ, 32 cases of CIN Ⅱ, 42 cases of CIN Ⅲ, and 12 cases of cervical cancer.Results:HR-HPV integration was detected in 80.2% (126/157) of the 157 HR-HPV positive samples. The incidence of HR-HPV integration in cervical cancer patients was 12/12, which was higher than that in normal women (77%, 24/31). The incidence of HPV16 integration was significantly higher in high-grade lesions, and the incidence of HPV16 integration was 43% (18/42) in CIN Ⅲ patients and 8/12 in cervical cancer patients ( P<0.001). A total of 14 438 integration events were detected in 126 samples with HPV integration. The integration sites were mainly distributed in the host intergenic region (51.0%, 7 359/14 438) and intronic region (38.1%, 5 494/14 438), and the integration frequency of viral L1 gene was the highest (28.4%, 4 498/16 781). Functional enrichment analysis showed that HPV integration-related host genes were significantly enriched in transport of small molecules,cyclic guanosine monophosphate (cGMP)-protein kinase G (PKG) signaling pathway, and purine ribonucleotide biosynthetic process, which synergistically drove carcinogenesis through multiple mechanisms. Conclusions:HPV integration events are significantly associated with the progression of cervical lesions. HPV integrated detection based on cervical exfoliated cells is expected to optimize the current screening strategy, reduce excessive intervention of HPV positive women and facilitate their accurate triage management.

Objective To analyze various scanning parameters and contrast agent injection schemes,and explore the feasibility of three-low scanning technology characterized by lower radiation dose,slower injection rate and reduced contrast agent dosage in coronary angiography with wide-detector CT.Methods A total of 210 patients who underwent coronary angiography were recruited and randomly divided into group A(routine group,n=105)and group B(three-low group,n=105),and all of them were examined using the Revolution CT from the American GE company.Group A and group B adopted 120 and 100 kV tube voltages,respectively.The contrast injection rate and contrast agent dosage were calculated using formulas based on body mass index and beat per minute.Image quality was objectively evaluated using CT number,signal-to-noise ratio and contrast-to-noise ratio,and subjectively scored using Likert 5-point method.Results No statistical differences were found in the basic data between two groups(P>0.05).The CT numbers of the aortic sinus orifice in coronary artery images obtained from group A and group B were(442.70±58.26)and(454.11±62.36)HU,respectively.The differences between two groups in CT number,image score,signal-to-noise ratio,and contrast-to-noise ratio were trivial(P>0.05),while statistically significant differences were noted in injection rate,contrast agent dosage,tube current,and effective radiation dose(P<0.05).Group B reduced the effective radiation dose by 33.89%as compared with group A.Conclusion Based on the patient's body mass index and beat per minute,a personalized contrast agent injection scheme can be developed.Both routine group and three-low group can obtain image quality that meets imaging diagnosis requirements,and the latter has better image quality,demonstrating that the three-low scheme benefits the patients more for it can reduce the patient's radiation dose and contrast agent dosage while achieving higher image quality.

Objective To observe the value of 2D SECara-Net and 3D U2-Net models constructed based on 2D maximal intensity projection(MIP)and 3D time-of-flight MR angiography(3D TOF-MRA)images,respectively,also of their combination for MRA detecting unruptured saccular intracranial aneurysms(USIA).Methods Totally 973 patients with single USIA and 300 subjects who underwent healthy physical examination were retrospectively collected and divided into training set(n=923,containing 723 cases of USIA and 200 healthy subjects)and test set(n=350,containing 250 cases of USIA and 100 healthy subjects)at the ratio of 7:3.Pre-processed 3D TOF-MRA and the obtained 2D-MIP images in training set were imported into 3D U2-Net and 2D SECara-Net models for training and adjusting parameters,respectively.The efficiency of 2 models and their combination for detecting USIA were evaluated.Results The sensitivity,specificity and accuracy of 2D SECara-Net model for detecting USIA in test set was 78.80％(197/250),95.00％(95/100)and 83.43％(292/350),of 3D U2-Net model was 82.80％(207/250),86.00％(86/100)and 83.71％(293/350),respectively.The specificity of 2D SECara-Net model was higher than that of 3D U2-Net model(P=0.030),while no significant difference of sensitivity nor accuracy was found between 2 models(both P＞0.05).The specificity of the combination of the 2 models was 99.00％(99/100),higher than that of 3D U2-Net model(P＜0.05),and the sensitivity and accuracy of the combination was 91.20％(228/250)and 93.43％(327/350),respectivelty,both higher than those of 2 single models(all P＜0.05).Conclusion 2D SECara-Net and 3D U2-Net models had similar,sensitivity and accuracy for MRA detecting USIA.Combination of them could improve the detecting efficacy.
