Objective:To sinicize the Obsessive and Compulsive Behaviors Scale of Mothers in Postpartum Period Regarding Baby Care (OCBS-MPPRBC) to test its reliability and validity, and to provide an evaluation tool for evaluating the degree of compulsive behaviors of postpartum mothers regarding baby care.Methods:Following the principles of Brislin translation, back translation and cross-cultural adaptation, the Chinese version of OCBS-MPPRBC was formed. A convenient sampling method was used to investigate 360 women in Mianyang Central Hospital from November 2023 to February 2024, and to test the reliability and validity of the Chinese version OCBS-MPPRBC. The critical ratio method and the total correlation analysis method were used for item analysis, the reliability test was based on Cronbach α coefficient and half-reliability method, and the content validity index, exploratory factor analysis, confirmatory factor analysis and aggregate validity were used for validity test. Results:A total of 352 women aged 21-41 (31.55 ± 3.17) years who met the exclusion criteria were included. The Chinese version of OCBS-MPPRBC contained 9 items, and 2 common factors were extracted by exploratory factor analysis, and the cumulative total variance contribution rate was 65.523%. The content validity index of the scale level was 0.89, the content validity index of each item level was 0.86-1.00, and the Cronbach α coefficient of the total scale was 0.844, and the half-folded reliability was 0.759. The results of confirmatory factor analysis showed that the fitting index of the Chinese version of the OCBS-MPPRBC model was better. Conclusions:The Chinese version of the OCBS-MPPRBC scale has good reliability and validity, and has good operability, which can be used to evaluate the degree of compulsive behavior of postpartum mothers about baby care in China.

This case report describes the diagnostic and therapeutic management of a 67-year-old fe-male with a 40-year history of Sj?gren disease(SjD)who was hospitalized for evaluation of recurrent fever lasting over one month.The patient's initial diagnosis of SjD was established four decades earlier based on clinical manifestations,serological findings,and evidence of glandular damage.Her clinical presenta-tion included recurrent parotid gland enlargement accompanied by sicca symptoms,notably persistent xerostomia and xerophthalmia,followed by progressive dental caries.Serological studies demonstrated positivity for antinuclear antibodies,anti-SSA/Ro,and anti-α-fodrin antibodies.Objective assessments confirmed significant ocular involvement(Schirmer's test≤5 mm/5 min)and pulmonary interstitial changes on chest CT,consistent with the 2016 American College of Rheumatology and European League Against Rheumatism(ACR/EULAR)classification criteria for SjD.The patient's condition remained sta-ble under low-dose corticosteroids and disease-modifying anti-rheumatic drugs(DMARDs)until the re-cent onset of prolonged fever,necessitating evaluation for fever of unknown origin.Differential diagnoses considered disease flare,infection,and malignancy.The European Sj?gren's Syndrome Disease Activity Index(ESSDAI)score was 5 points,indicating moderate systemic disease activity.Initial laboratory in-vestigations revealed no evidence of infection,and empirical anti-infective therapy proved ineffective.No-tably,despite the absence of lymphadenopathy,laboratory findings including borderline positive IgM λ M-protein,elevated lactate dehydrogenase,hyperferritinemia,and increased β2-microglobulin levels raised suspicion for lymphoproliferative disorders,given the established association between SjD and lymphoma.Bone marrow aspiration showed no significant abnormalities,but PET/CT imaging detected hypermetabolic lesions in the left breast and right distal femur,suggesting potential malignancy.Subse-quent histopathological examination of the breast lesion confirmed non-Hodgkin's lymphoma(NHL),specifically diffuse large B-cell lymphoma(DLBCL)of the germinal center B-cell(GCB)subtype.Treatment with R-CHOP chemotherapy(rituximab,cyclophosphamide,doxorubicin,vincristine,and prednisone)induced complete metabolic remission after three cycles.However,she subsequently developed treatment-related complications,including myelosuppression and pulmonary infection.This case underscores the importance of maintaining a high index of suspicion for atypical site involvement in SjD patients,particularly when lymphoma risk factors are present.Comprehensive differential diagnosis should include lymphoma and other malignancies,and the diagnostic value of PET/CT and histopatholog-ical examination in disease evaluation is emphasized.SjD complicated by breast lymphoma is exceptional-ly rare,and its pathogenesis may involve lymphocytic infiltration,abnormal activation of lymphocytes,formation of ectopic germinal centers in the breast,and eventual malignant transformation.These mecha-nisms require further investigation through clinical and basic research studies.

Oropharyngeal squamous cell carcinoma(OPSCC)is a malignant tumor originating from the squamous epithelium of the oro-pharyngeal mucosa,accounting for more than 90％of oropharyngeal malignancies.In recent years,human papillomavirus(HPV)infec-tion has become one of the primary etiological factors of oropharyngeal squamous carcinoma.The incidence of HPV-associated oropharyn-geal squamous carcinoma has been rising annually,with a noticeable trend toward younger populations,posing a significant threat to hu-man health.Due to the distinct biological behavior and clinical characteristics of HPV-associated oropharyngeal squamous carcinoma com-pared to its non-HPV-related counterpart,the diagnostic and treatment strategies for oropharyngeal squamous carcinoma have undergone substantial changes.Prevention and screening for oropharyngeal squamous carcinoma are of critical importance.The diagnostic and treat-ment process involves multi-disciplinary collaboration,including oral and maxillofacial surgery,otolaryngology,head and neck surgery,oncology,radiology and pathology.Based on evidence from clinical practice,a comprehensive,integrated diagnostic and therapeutic ap-proach has been established,centered around the concept of"prevention,screening,diagnosis,treatment,and rehabilitation",covering the entire patient lifecycle and providing a valuable reference for clinical practice.

In recent decades,the incidence of human papillomavirus(HPV)-associated oropharyngeal squamous cell carcinoma(OPSCC)has shown a marked increase.Significant changes have also occurred in the OPSCC diagnosis and treatment paradigm.Deter-mining HPV status prior to treatment is now essential,and radiotherapy/chemotherapy,immunotherapy,and minimally invasive surgical techniques have progressively emerged as key modalities for managing OPSCC.However,alongside these paradigm shifts,a comprehen-sive technical consensus guiding the entire diagnostic and therapeutic process for OPSCC patients is currently lacking.Given China's large population base and the rising incidence of OPSCC,an expert panel convened to develop a clinical technical consensus on OPSCC diagno-sis and management tailored to China's specific context.This consensus aims to further enhance and standardize understanding of OPSCC management techniques among relevant healthcare professionals.

Oral squamous cell carcinoma(OSCC)is a malignant lesion originating from the oral mucosal squamous epithelium,account-ing for over 80％of oral and maxillofacial malignancies.Key etiological factors include tobacco,alcohol abuse,and betel quid chewing.In China,its incidence has shown an overall upward trend,posing a significant threat to public health.OSCC exhibits high local invasive-ness,making early diagnosis critical for improving prognosis.Its clinical management requires close multidisciplinary collaboration among oral and maxillofacial surgery,head and neck surgery,radiation oncology,medical oncology,reconstructive surgery,radiology,patholo-gy,and nutritional support teams.Given the increasing disease burden of OSCC and rapid development of multidisciplinary collaborative models,an expert panel has formulated this integrated management consensus based on evidence-based medicine and extensive deliber-ation.Centered on the'Prevention-Screening-Diagnosis-Treatment-Rehabilitation'framework,the consensus provides comprehensive guidance for the entire disease course of OSCC patients,aiming to standardize clinical practice.

The advancement of surgical techniques enables effective treatment for many patients with oral and maxillofacial tumors.How-ever,post-surgery problems such as chewing,swallowing and speech difficulty may arise due to the defects in speech organs and inade-quate compensatory function of tissue flap repair.Speech disorders,in particular,isolate patients by making it difficult for them to com-municate with others,not only impact their quality of life but also potentially lead to psychological problems and social interaction disor-ders.Although the decline in life quality and other related issues caused by speech dysfunction due to surgery and radiotherapy or chemo-therapy have been widely recognized,there is currently no standardized and universally applicable assessment method and standardized re-habilitation treatment management guideline or consensus for speech disorders following oral and maxillofacial tumor surgery at home and abroad.Based on previous clinical practice,combined with the characteristics of speech disorders in patients after oral and maxillofacial tumor surgery,the clinical experience of the experts in maxillofacial tumor surgery and rehabilitation and the relevant domestic and foreign literature,relevant experts organized discussions and modifications,reach a consensus on core content such as the assessment of speech disorders and the implementation plan for early rehabilitation treatment management,providing a reference for clinical practice,in order to improve patients'speech-related life quality and enhance the assessment and rehabilitation treatment techniques for speech disorders after oral and maxillofacial tumor surgery.

Objective:To explore the features of levels of lung cancer biomarkers in peripheral blood of adults in Beijing and surrounding areas, and establish personalized reference intervals for these biomarkers.Methods:A cross sectional study was conducted. The lung cancer biomarker data, including carcinoembryonic antigen (CEA), cytokeratin 19 fragment antigen 21-1 (CYFRA21-1), neuron specific enolase (NSE), progastrin-releasing peptide (ProGRP), and squamous cell carcinoma antigen (SCC-Ag), collected from adults who underwent cancer prevention examinations at the Cancer Hospital of the Chinese Academy of Medical Sciences from July 2021 to July 2022 were retrospectively analyzed. The interquartile range method was used to eliminate outliers, and the P95 value was calculated. Upper limit of 5 lung cancer biomarkers in different gender and age groups were obtained by referring to the reference intervals of quantitative analytes in the clinical laboratory (WS/T 402-2024). By analyzing the data of 208 adults who underwent cancer prevention physical examinations at the same center in June 2021 and 140 patients with benign lung masses confirmed by surgical resection pathology from January 2016 to June 2022, the established reference intervals for biomarkers were validated. Results:Two thousand six hundred and twenty-six cases of apparently healthy physical examiners were included for constructing reference intervals, including 1 456 males (55.4%) and 1 170 females (44.6%); the age range was 20-88 years old. The serum levels [ M ( Q1, Q3)] of CEA, NSE, ProGRP, SCC-Ag and CYFRA21-1 in 2 626 cases were 1.63 (1.07, 2.43) ng/ml, 13.08 (11.44, 14.77) ng/ml, 34.93 (29.02, 42.19) pg/ml, 0.80 (0.60, 1.00) ng/ml and 1.96 (1.48, 2.63) ng/ml, respectively. The serum levels of CEA [1.88 (1.22, 2.76) ng/ml vs. 1.41 (0.93, 2.02) ng/ml], NSE [13.31 (11.87, 15.00) ng/ml vs. 12.69 (10.96, 14.53) ng/ml], SCC-Ag [0.9 (0.7, 1.1) ng/ml vs. 0.7 (0.6, 0.9) ng/ml], and CYFRA21-1 [2.02 (1.53, 2.71) ng/ml vs. 1.87 (1.40, 2.51) ng/ml] in males were higher than those in females, and ProGRP [34.00 (28.25, 41.55) pg/ml vs. 36.12 (29.97, 42.98) pg/ml] was lower than that in females, and the differences were statistically significant (all P < 0.001). There were statistically significant differences in serum CEA levels between the groups of ≤ 40 years old (458 cases), >40-50 years old (827 cases), >50-60 years old (783 cases), >60-70 years old (412 cases), and >70 years old (146 cases) in pairwise comparison (all P < 0.05). Except for the age groups of ≤ 40 years old and >40-50 years old and the age groups of >60-70 years old and >70 years old, there were statistically significant differences in serum NSE levels among the other age groups in pairwise comparison (all P < 0.05). There were statistically significant differences in serum ProGRP levels between the 5 age groups (all P < 0.05). There were statistically significant differences when comparing the serum SCC-Ag level in the >40-50 age group, >50-60 age group and >60-70 age group with that in the ≤40 age group and >70 age group, respectively (all P < 0.05). However, there was no statistically significant difference between the other age groups in pairwise comparison (all P > 0.05). There were statistically significant differences in serum CYFRA21-1 levels between the 5 age groups (all P < 0.05). When gender and age were not distinguished, the P95 values of serum CEA, NSE, ProGRP, SCC-Ag and CYFRA21-1 levels were 4.44 ng/ml, 16.61 ng/ml, 57.65 pg/ml, 1.50 ng/ml, and 4.21 ng/ml, respectively. Considering gender and age, except for the >70 age group with no statistically significant difference in the P95 value of serum CEA level between males and females ( P > 0.05), the P95 value of serum CEA level in males was higher than that in females in all other age groups (all P < 0.001); the P95 values of serum CEA level in both males and females increased with age, but showed a decreasing trend in males over the age of 70. The P95 value of serum NSE level in males was higher than that in females in the age groups of ≤ 40 years and >40-50 years (both P < 0.05), while there was no statistically significant difference in the P95 value of serum NSE level between males and females in other age groups (all P > 0.05). The P95 values of serum NSE level in both males and females decreased firstly and increased later with age, reaching their highest levels at the age of >70. The P95 values of serum ProGRP level in females aged ≤ 40 and >50-60 were higher than those in males (both P < 0.05), while there was no statistically significant difference in the P95 value of serum ProGRP level between genders in other age groups (all P > 0.05); the P95 values of serum ProGRP level in both males and females increased with age. There was no statistically significant difference in the P95 value of serum SCC-Ag level between males and females in the ≤ 40 age group ( P > 0.05), while the P95 value of serum SCC-Ag level in males was higher than that in females in all other age groups (all P < 0.05). The P95 values of serum SCC-Ag level in males increased with age, while they were stable in females. There was no statistically significant difference in the P95 value of serum CYFRA21-1 level between males and females in the >60-70 age group ( P > 0.05), while the P95 value of serum CYFRA21-1 level in males was higher than those in females in all other age groups (all P < 0.05); the P95 values of serum CYFRA21-1 level in both males and females increased with age. Based on data from 2 626 apparently healthy physical examiners, reference intervals for the levels of 5 lung cancer biomarkers were constructed in different age groups of different genders. Validation was conducted on 208 physical examiners and 140 patients with benign lung lesions, and it was found that the compliance rate of using newly created reference intervals for different gender and age groups to interpret detection results was >90%, and the validation was passed. Conclusions:There are gender and age differences in the reference intervals of CEA, CYFRA21-1, NSE, ProGRP, and SCC-Ag in peripheral blood of adults in Beijing and surrounding areas. The constructed reference intervals of gender and age for biomarkers have been validated and shown good results, providing reference for optimizing the clinical application of lung cancer-related biomarkers.
