OBJECTIVE: To investigate the detection patterns, clinical phenotypic characteristics, and differences in diagnostic timeliness of Klinefelter syndrome (KS) across prenatal and postnatal stages, with an aim to provide a basis for optimizing strategies for early screening, diagnosis, and intervention. METHODS: A retrospective study was conducted to analyze data from two phases. The prenatal diagnosis group included 33,302 pregnant women who underwent amniocytic karyotyping due to advanced maternal age, abnormal ultrasound findings, or high-risk non-invasive prenatal testing (NIPT). The postnatal diagnosis group included 52,101 patients who underwent peripheral blood karyotyping due to primary infertility, abnormal external genitalia, or growth and developmental abnormalities. Additionally, medical histories of adult diagnosed patients were reviewed retrospectively to identify early occult symptoms. This study was approved by the Medical Ethics Committee of Chengdu Women's and Children's Central Hospital (Ethics No.: LCYJ-2025-030). RESULTS: In the prenatal group, 96 cases of KS were detected (detection rate 0.29%). The primary indications for referral were NIPT indicating sex chromosome abnormalities (45.83%), advanced maternal age (16.66%), and ultrasound abnormalities (17.70%). In the postnatal group, 128 cases of KS were detected (detection rate 0.25%). Clinical presentations were primarily primary infertility/azoospermia (77.34%), and the patients were predominantly adults (84.40%). Retrospective analysis revealed that adult patients presented with specific physical signs that had been overlooked during childhood. CONCLUSION As KS lacks typical early clinical manifestations, diagnosis is often delayed until adulthood when reproductive needs arise, showing a pattern of "passive detection" and resulting in missed opportunities for optimal intervention. By conducting a comparative analysis of prenatal diagnostic data and postnatal retrospective data, a risk association model linking prenatal screening indications with childhood-specific signs was developed. This study has provided empirical evidence for establishing a multidisciplinary, full life-cycle management system of "screening ~ diagnosis ~ monitoring ~ intervention" helping to shift from "passive detection in adulthood" to "proactive management across the entire life course," and laid a foundation for improving early diagnosis rate and long-term quality of life for patients.

Objective To establish an optimized diagnostic model for hepatocellular carcinoma(HCC),designated as G-GADA,in chronic hepatitis B(CHB)patients based on the parameters of age,sex,alpha-fetoprotein(AFP),des-γ-carboxy prothrombin(DCP),and Golgi protein 73(GP73),to address the problems of low sensitivity and specificity in the early diagnosis of hepatitis B virus(HBV)-related liver cancer,and to assess the value of this model in the diagnosis of HCC.Methods A retrospective analysis was performed for 201 CHB patients(CHB group),137 patients with HBV-related liver cirrhosis(LC group),and 111 treatment-na?ve patients with newly diagnosed HCC(HCC group)who were admitted to Mengchao Hepatobiliary Hospital of Fujian Medical University from June 2015 to June 2020.Serological markers(AFP,DCP,alpha-fetoprotein L3%[AFP-L3%],and GP73)were compared between groups and were analyzed in terms of their differences from the clinical and tumor characteristics of HCC patients,and the Spearman correlation analysis was used to assess the correlation between different markers.A Logistic regression analysis was used to establish a diagnostic model for liver cancer,and the receiver operating characteristic(ROC)curve was used to assess the diagnostic performance of each marker.Results Comparison of clinical features between CHB,LC,and HCC patients showed that HCC patients had significantly higher age,proportion of male patients,and serum levels of DCP,AFP,GP73,and AFP-L3%(all P<0.05).In HCC patients,DCP levels are associated with tumor size and microvascular invasion;AFP levels are related to patient age,tumor size,tumor number,distant metastasis,and microvascular invasion;AFP-L3%levels are associated with patient age,tumor size,tumor number,distant metastasis,Milan staging,and microvascular invasion;GP73 levels are linked to tumor number,distant metastasis,and microvascular invasion(all P<0.05).The correlation analysis of the serum markers showed a strong positive correlation between AFP and AFP-L3%(r=0.71,P<0.05)and a moderate positive correlation between AFP and GP73(r=0.33,P<0.05)and between AFP-L3%and GP73(r=0.41,P<0.05).Based on the features of age,sex,DCP,AFP,and GP73,the multivariate Logistic regression analysis was used to establish a G-GADA diagnostic model for HCC,and for all patients,the G-GADA model had an area under the ROC curve(AUC)of 0.915(95%confidence interval[CI]:0.875-0.945)in the derivation cohort and 0.913(95%CI:0.862-0.950)in the validation cohort for the diagnosis of HCC.In the AFP-negative patients,the G-GADA model achieved an AUC of 0.884(95%CI:0.833-0.924)in the derivation cohort and 0.851(95%CI:0.779-0.907)in the validation cohort,and in the patients with liver cirrhosis,the G-GADA model achieved an AUC of 0.901(95%CI:0.841-0.944)in the derivation cohort and 0.885(95%CI:0.806-0.940)in the validation cohort.Conclusion The G-GADA diagnostic model based on multiple variables significantly improves the detection rate of HCC,and demonstrates superior diagnostic performance in patients with low AFP expression and those with liver cirrhosis.The G-GADA model has a better clinical application value in the noninvasive diagnosis of HCC.

Objective:To explore the impact of a staged trauma integrated treatment model based on information network platforms on the emergency treatment outcomes of patients with severe cranial injury.Methods:A convenience sampling method was used to select 80 patients with severe cranial injury treated at Yiwu Central Hospital from June 2023 to June 2024. Patients admitted from June to December 2023 were assigned to the control group ( n=37), while patients admitted from January to June 2024 were assigned to the intervention group ( n=43). The control group received conventional emergency treatment for cranial injury, while the intervention group received the staged trauma integrated treatment model based on an information network platform. The emergency response time (response time, triage time, emergency room treatment time, and handover time to the ward), National Institutes of Health Stroke Scale (NIHSS) score, Glasgow Coma Scale (GCS) score, incidence of complications, and family satisfaction were compared between the two groups. Results:After intervention, the intervention group had shorter emergency response time, triage time, emergency room treatment time, and handover time to the ward compared to the control group, with statistically significant differences ( P<0.01). The NIHSS score in the intervention group was lower, and the GCS score was higher, with statistically significant differences ( P<0.05). The incidence of complications in the intervention group was lower, and family satisfaction was higher compared to the control group, with statistically significant differences ( P<0.05) . Conclusions:The staged trauma integrated treatment model based on an information network platform can optimize the emergency treatment process for severe cranial injury, shorten treatment times, improve hospital-to-hospital and interdepartmental coordination, reduce neurological damage and complication rates, and increase family satisfaction. It is worth promoting for clinical use.

Objective:To investigate the prevalence of hyperuricemia (HUA) in Bozidun Kirghiz township of Xinjiang Aksu region, and to explore the risk factors for the occurrence of HUA in the local area.Methods:A cross-sectional survey study was conducted by randomly selecting 9 villages in Bozidun Kirgiz Township by the whole-group sampling method and questionnaire were distributed to the households. The questionnaire included: demographic information, history of past illness, personal history, and all subjects were measured for height, weight, blood pressure, abdominal circumference, etc. The diagnostic of HUA if the serum uric acid (SUA) level >420 μmol/L in men or >360 μmol/L in women. The incidences of HUA in different age, sex, food type and life style behavior were analyzed. T test, non-parametric test and Chi-square test were used to analyze the differences among the groups, and logistic regression was used to analyze the risk factors. Results:①A total of 2 138 subjects were surveyed, among which 68 patients were with HUA, the prevalence of HUA in Bozidun Kirghiz township, Aksu region in the general population was 3.18%(68/2 138); the prevalence rate in men was 4.60%(45/978), 45 patients were identified; and the prevalence rate in women was 1.98%(23/1 160), 23 patients were identified. The peak age of HUA in male and female patients was 51~60 years old. ②The prevalence of HUA was lower in those who consumed dairy products ( χ2=6.91, P=0.017), nuts ( χ2=8.43, P=0.038) and eggs ( χ2=7.38, P=0.023), and lower in those who consumed more. Different intake of cereals ( χ2=0.87, P=0.647), meat( χ2=0.82, P=0.662), vegetables and fruits( χ2=5.22, P=0.073) had no effect on the prevalence of HUA.③In terms of different life behaviors, the prevalence of HUA in men who had been smoking was higher than those who had never smoked (57.78%, 28.89%, 13.33%, χ2=8.16, P=0.017). In the relationship between drinking and HUA, the prevalence rates of male always drinking, ever drinking and never drinking were 80.00%, 11.11% and 3.89%, respectively, the difference was statistically significant ( χ2=6.67, P=0.038). ④Multi-factor logistic regression analysis showed that high BMI, old age, high TG, increased Cr and increased WBC were risk factors for the occurrence of HUA [ OR(95% CI)=1.13(1.04, 1.23), 1.03(1.00,1.05),1.39(1.00, 1.93), 1.03(1.02, 1.05), 1.27(1.07, 1.49), all P<0.05]. Conclusion:The prevalence of HUA in Bozidun Kirgiz township in Aksu prefecture of Xinjiang is lower than that in other areas with continental climate. High BMI, old age, high TG, increased Cr and increased WBC count are risk factors for the development of HUA .

Objective:To investigate the expression level and application value of anti-carbamylated protein(CarP)antibody in rheumatoid arthritis(RA).Methods:Demographic data and laboratory test results of RA patients,non-RA patients and healthy controls in the physical examination center were re-viewed from December 2018 to June 2019 in the Rheumatology and Immunology Department of the Peo-ple's Hospital of Xinjiang Uygur Autonomous Region.The serum concentrations of anti-CarP antibodies in all the subjects were measured by ELISA and statistically analyzed.Results:A total of 259 subjects were included in this study,including 158 in the RA group(45 serum-negative RA patients),59 in the non-RA group and 42 in the healthy control group.The concentration of anti-CarP antibody in RA group[8.31(5.22,15.26)U/mL]was higher than that in non-RA group[4.50(3.35,5.89)U/mL]and healthy control group[3.46(2.76,4.92)U/mL].The concentration of anti-CarP antibody in non-RA group was not significantly different from that in healthy control group(P=0.10).Receiver operating characteristic(ROC)curve analysis showed that the sensitivity of anti-CarP antibody in the diagnosis of RA was 58.2％,and the specificity was 93.1％.The sensitivity of the combined detection of anti-CarP antibody,anti-cyclic peptide containing citrulline(CCP)antibody and rheumatoid factor(RF)was 82.3％,and the specificity was 96.5％.The positive rate of anti-CarP antibody in serum-negative RA patients was 44.4％(20/45).Univariate Logisitic regression analysis showed that age,C-reactive pro-tein(CRP),erythrocyte sedimentation rate(ESR),RF,glucose-6-phosphate isomerase(GPI),anti-CCP antibody and anti-CarP antibody were risk factors for RA.Multivariate Logisitic regression analysis showed that anti-CCP antibody and anti-CarP antibody were independent risk factors for RA.Spearman correlation analysis showed that there was no significant correlation between anti-CarP antibody and swol-len joint count(SJC),tenderness joints count(TJC),ESR,disease activity score for 28 joints(DAS28),clinical disease activity index(CDAI),simplified disease activity index(SDAI).The concentration of anti-CarP antibody in RA with bone erosion(n=88)was higher than that in RA without bone erosion(n=70),and there was significant difference between the two groups(P＜0.05).Conclusion:Anti-CarP antibody is an effective serological marker for the diagnosis of RA.The combined detection of RF,anti-CCP antibody and anti-CarP antibody can improve its diagnostic value,and anti-CarP antibody may be an effective assistant diagnostic tool for serum negative RA.The high serum concentration of anti-CarP antibody in patients with RA may indicate an increased risk of bone erosion and should be treated early,but further cohort studies are needed for follow-up observation.

Objective:To discuss the differences in eosinophil(EOS)infiltration in cervical tissue and its relationship with cervical-related diseases,and to clarify the effect of EOS on the occurrence and development of cervical intraepithelial neoplasia(CIN)and cervical cancer.Methods:The clinical data of 256 patients with cervical diseases were collected and divided into cervical cancer group(n=46,including 26 cases of squamous cell carcinoma,15 cases of adenocarcinoma,and 5 cases of adenosquamous carcinoma),chronic cervicitis group(n=50),CIN stage Ⅰ group(n=50),CIN stage Ⅱ group(n=50),CIN stage Ⅲ group(n=30),and normal group(adjacent normal cervical tissue,n=30)based on their conditions.Colposcopy was used to observe the morphology of cervical tissue of the patients in various groups;thin-layer liquid-based cytology test(TCT)was used to observe the morphology of the cervical exfoliated cells in various groups;hybrid capture-chemiluminescence method was used to detect the human papillomavirus(HPV)infection in cervical tissue of the patients in various groups;HE staining was used to observe the pathomorphology of cervical tissue of the patients in various groups;Congo red staining was used to detect the numbers of EOS infiltration in cervical tissue of the patients in various groups;Pearson correlation analysis was used to analyze the correlation between the number of EOS infiltration and the malignancy degree of cervical cancer.Results:The cervical surface of the patients in normal group was smooth and pink,with uniformly distributed capillaries;the cervical surface of the patients in chronic cervicitis group showed red inflammatory changes,with some accompanied by Nabothian cysts and varying degrees of erosion and ulcers;the patients in CIN stage Ⅰ,CIN stage Ⅱ,and CIN stage Ⅲ groups showed epithelial ulcers,thickening,and irregular morphology,with mosaic and punctate vessels;the cervical surface of the patients in cervical cancer group showed raised areas with neoplasms and necrotic ulcers,and they were fragile and prone to bleeding.After acetic acid staining,no obvious changes of the patients in normal group were observed.The cervix of the patients in chronic cervicitis group showed slight white changes that lasted for a short time;in CIN stage Ⅰ,CIN stage Ⅱ,and CIN stage Ⅲ groups,irregular thin acetowhite epithelium with map-like borders was observed,with increasingly acetowhite reactions and larger areas as the stages advanced.The cervix of the patients in cervical cancer group showed thick acetowhite epithelium that lasted longer,with rigid and clear contours.After iodine staining,the cervix of the patients in normal group was brown,with uniform coloration;the cervix of the patients in chronic cervicitis group showed poor coloration in inflammatory lesion areas;the cervix of the patients in CIN stage Ⅰ group showed iodine coloration in metaplastic areas,while the cervix of the patients in CIN stage Ⅲ group showed poor coloration in larger lesion areas;the cervix of the patients in cervical cancer group showed irregular surfaces with cauliflower-like growth and no coloration after iodine staining,appearing orange-yellow or mustard yellow.The TCT observation results showed there were no heteromorphic cells and few inflammatory cells in cervical exfoliated cells of the patients in infiltration in normal group;there were numerous neutrophils and EOS in exfoliated cervical cells without heteromorphic cells in chronic cervicitis group.The heteromorphic binucleated cells with high nuclear-cytoplasmic ratios and deeply stained nuclei were observed in cervical exfoliated cells of the patients in CIN stage Ⅰ and CIN stage Ⅱ groups.More heteromorphic cells with high nuclear-cytoplasmic ratios and irregular nuclear membranes were showed in cervical exfoliated cells of the patients in CIN stage Ⅲ group.The cervical exfoliated cells of the patients in cervical cancer group showed large and prominent nucleoli,clustering into syncytial changes.Compared with normal group,the atypial of cervical exfoliated cells in CIN stage Ⅰ,CIN stage Ⅱ,CIN stage Ⅲ,and cervical cancer groups was increased.The hybrid capture-chemiluminescence results showed that compared with normal and chronic cervicitis groups,the numbers of HPV infection and TCT heteromorphic cells of the patients in CIN stage Ⅰ,CIN stage Ⅱ,and CIN stage Ⅲ groups were increased(P<0.05);compared with CIN stage Ⅰ,CIN stage Ⅱ,and CIN stage Ⅲ groups,the numbers of HPV infection and TCT heteromorphic cells of the patients in cervical cancer group were increased(P<0.05).The HE staining results showed normal cell morphology and structure in normal group,with infiltration of inflammation cells such as neutrophils,monocytes,macrophages,EOS,and lymphocytes;in chronic cervicitis group,the infiltration of inflammatory cells was increased;in CIN group,the cervical cells showed slightly larger nucleoli and heteromorphic cells,with inflammatory cells mainly distributing around the hetermomorphic cells;in cervical cancer group,the cervical cells showed large and deeply stained nucleoli with significant atypia,and the infiltration of inflammatory cells around the cancer cells was increased.Compared with normal group,the numbers of inflammatory cells and EOS infiltration in cervical tissue of the patients in chronic cervicitis group were increased(P<0.05),and the numbers of inflammatory cells and EOS infiltration of the patients in CIN group were increased(P<0.05);compared with chronic cervicitis group,the number of inflammatory cells and EOS infiltration of the patients in CIN group were decreased(P<0.05);compared with chronic cervicitis group and CIN group,the numbers of inflammatory cells and EOS infiltration of the patients in cervical cancer group were increased(P<0.05).The EOS in cervical cancer tissue was mainly distributed around the cancer nests;compared with CIN stage Ⅰ group,the numbers of EOS infiltration in CIN stage Ⅱ and CIN stage Ⅲ groups were increased(P<0.05);compared with CIN stage Ⅱ group,the number of EOS infiltration in CIN stage Ⅲ group was increased(P<0.05).The higher the malignancy degree of the tumor,the more EOS infiltration was observed,and the number of EOS infiltration was positively correlated with the invasion depth of cervical cancer(r=0.533 0,P<0.01).Conclusion:HPV infection and EOS infiltration play a role in promoting the and occurrence development of cervical precancerous lesions and cervical cancer.

Opioid-free anesthesia(OFA)is a multimodal analgesic strategy that combines multiple non-opioid drugs and/or techniques to obtain high-quality anesthesia.With the popularization of the concept of enhanced recovery after surgery(ERAS),OFA has become a common concern hot spot for perioperative phy-sicians.OFA is in line with the ERAS concept,and under multimodal anesthesia and pain management,it can reduce surgical stress,inflammation reaction and postoperative complications,significantly improve the prog-nosis of patients,promote postoperative rapid recovery and reduce the burden of medical and health resources.This article reviews the adverse reactions of opioids,OFA concept and indications,the clinical application of OFA in recent years,the existing controversies and problems to be solved.
