Objective:To analyze the relevant studies on fertility concerns intervention programs for breast cancer survivors of childbearing age, and identify the specific content, outcome indicators and intervention effects of intervention, in order to provide reference for clinical staff to implement relevant intervention.Methods:According to the research method of scope review, the studies on the fertility concerns with breast cancer patients of childbearing age in China National Knowledge Infrastructure, WanFang, VIP, China Biomedical Literature Database, CINAHL, PubMed, Cochrane Library, Web of Science etc. were searched. The search period was from database establishment to May 9, 2024. The included literature was classified and analyzed.Results:A total of 12 articles were included, 9 were randomized controlled trials, 2 were self-controlled before and after studies, and 1 was a prospective cohort study. Fertility concerns intervention programs included group fertility counseling centered on couples, fertility support based on a multidisciplinary team collaboration model, and fertility management based on "Internet + reproductive health". The duration of intervention was usually 4 or 24 weeks. The intervention had different effects on the level of fertility concerns, psychological state and marital status.Conclusions:At present, the intervention programs for fertility concerns of breast cancer survivors of childbearing age reflect the importance, professionalism, immediacy and interactivity, but China is in the initial stage, and there are still shortcomings in multidisciplinary teams, fertility referral system, and Internet platform construction. Future research should build a breast cancer fertility intervention program suitable for our country, and promote its application through the Internet.

Objective:To explore the correlation of bone metabolism with vitamin D and vitamin K levels in children with glucocorticoid-induced osteoporosis (GIOP) .Methods:A total of 120 GIOP children admitted to Neonatal Department of the First People’s Hospital of Chenzhou City, Hunan Province from Oct. 2022 to Dec. 2024 (GIOP group) and children without osteoporosis who received glucocorticoid therapy during the same period (the control group) were studied. Bone mineral density (BMD), biochemical indexes of bone metabolism and serum 25-hydroxyvitamin D (25 (OH) D), vitamin K1 (VitK1) and VitK2 were determined. BMD and bone metabolism indexes of GIOP children with different levels of 25 (OH) D, VitK1 and VitK2 were compared and their correlation was analyzed. Multiple linear regression analysis was conducted to analyze the independent factors affecting low BMD in GIOP children.Results:GIOP group had lower BMD, serum 25 (OH) D, VitK1 and VitK2 levels ( t=33.03, 42.22, 65.30, 86.16, P<0.05), while higher PINP, β-CTX and N-MID levels ( t=17.98, 34.78, 2.58, P<0.05); The levels of VitK1, VitK2, BMD, PINP, β-CTX and N-MID in GIOP children with different vitamin D and K levels were statistically significant ( F =54.31, 36.77, 82.32, 32.40, 22.80, 5.23), among which BMD was the lowest and PINP, β-CTX and N-MID levels were the highest ( P<0.05); The levels of 25 (OH) D, VitK1 and VitK2 were positively correlated with BMD ( r=0.54, 0.39, 0.47, P<0.05), but negatively correlated with PINP, β-CTX and N-MID ( r = -0.43, -0.34, -0.38, -0.39, -0.45, -0.44, -0.29, -0.32, -0.51, P<0.05); 25 (OH) D, VitK1 and VitK2 were protective factors for low BMD ( t=-2.76, -2.55, -3.51, P<0.05), while PINP, β-CTX, N-MID and hormone use time were risk factors ( t=2.48, 2.19, 2.22, 2.06, P<0.05) . Conclusions:The level of bone metabolism in children with GIOP is closely related to the levels of vitamin D and vitamin K. With the decrease of vitamin D and vitamin K levels, the decrease of BMD is more obvious. Therefore, vitamin D and vitamin K should be supplemented in a timely and reasonable manner for such children.

Objective:To evaluate the cognitive status for oral genetics among graduate students of stomatology, and to provide advice for teaching reform and design of oral genetics course.Methods:A questionnaire survey was conducted among first-year graduate students of stomatology in Medical School of Nanjing University enrolled in the academic year of 2022-2023. The questionnaire was designed for "Assessing cognition and attitudes towards oral genetics" and included four parts: assessment of students' level of awareness and knowledge about oral genetic disorders; understanding the role of genetic factors in stomatology; the causes of oral diseases; and awareness of oral genetic disorders and rare oral diseases. Students completed the questionnaire anonymously and voluntarily at the beginning and end of the course. Excel 2013 was used for data processing. SPSS 21.0 was used for rank sum test, chi-square test, and t-test for paired samples. Results:A total of 58 questionnaires were recovered (recovery rate 89.66%) and 52 questionnaires were valid (26 each at the beginning and end of the course). A total of 26 students aged (24.73±1.28) years were enrolled and 69.23% of the students treated patients with oral genetic disorders. Their knowledge of oral genetics increased significantly after the course ( Z=-3.74, P<0.001). Their familiarity with the number of rare oral diseases and oral genetic disorders increased significantly after the course [(18.34±8.61) vs. (29.69±10.39), t=5.95, P<0.001]. Conclusions:Students generally realize the importance of genetics in stomatology. The implementation of the course helps to improve students' cognition and clinical diagnosis and treatment of oral genetic diseases.

ObjectiveTo investigate the pathogenic spectrum and epidemiological characteristics of diarrheal disease in Fengxian District of Shanghai, and to provide scientific basis for the prevention and control of diarrheal diseases. MethodsBasic information of the initial adult cases visited diarrheal disease surveillance sentinel hospital in Fengxian District, Shanghai, was collected from August 2013 to 2023, and fecal samples were collected at 1∶5 sampling intervals to isolate and identify 5 kinds of diarrheagenic Escherichia coli (DEC), Salmonella (SAL), Vibrio parahaemolyticus, Campylobacter, Vibrio cholerae, Shigella and Yersinia enterocolitica (YE). Simultaneously, nucleic acid detection was performed for 3 kinds of rotavirus, 2 kinds of norovirus, intestinal adenovirus, astrovirus and sapovirus. ResultsA total of 1 861 cases of newly diagnosed diarrheal disease were reported, with the peak in July to August. Additionally, 704 surveillance samples were detected, with a total positive detection rate of 50.57%. The detection rates of bacterial, viral and mixed infection were 25.14%, 21.02% and 4.40%, respectively. Among the pathogens detected, DEC accounted for the highest (17.61%, 124/704), followed by norovirus (16.48%, 116/704), rotavirus (6.39%, 45/704), SAL (5.97%, 42/704) and Campylobacter (3.84%, 27/704). DEC detected were mainly enteroaggregative Escherichia coli and enterotoxigenic Escherichia coli, with no detection of Vibrio cholerae, Shigella and YE. The highest total pathogen detection rate was observed from June to September, and the detection peaks of norovirus were from March to June and from October to December, whereas that of DEC was from June to October. The detection rate of rotavirus peaked from January to February, but which was not detected between 2020‒2023. The SAL positive rate peak was in September, whereas that of Campylobacter was from July to September. ConclusionThe main pathogens detected in Fengxian District from 2013‒2019 are DEC, norovirus, rotavirus, SAL and Campylobacter. Different pathogens have different detection peaks, with bacteria predominating in summer and viruses in winter and spring. Prevention and control measures should be carried out according to the epidemiological characteristics of different seasons.

Objective:To identify the prognostic value of the Revised 15-item Myelodysplastic Syndrome-specific frailty scale (FS-15) in Chinese patients with myelodysplastic syndromes (MDS) .Methods:This retrospective study analyzed 812 patients with newly diagnosed MDS admitted to the Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences, and Peking Union Medical College from August 2016 to June 2023. Patients were assessed using the FS-15 and subsequently categorized into frail and non-frail groups. Clinical and laboratory characteristics, as well as overall survival (OS), were compared between these groups.Results:① The median patient age was 55 years ( IQR 45–64), with a median follow-up of 22.5 months (95% CI: 20.2–24.9) and a median OS of 43.3 months (95% CI: 36.8–49.8). The median FS-15 score was 0.42, with a cutoff value of 0.44. Male patients demonstrated higher median FS-15 scores than female patients (0.42 vs 0.38, P=0.006). In both the Revised International Prognostic Scoring System (IPSS-R; P=0.001) and Molecular International Prognostic Scoring System (IPSS-M; P=0.014) stratifications, FS-15 scores were significantly higher in the very high-risk group compared with the very low-risk group. ② The median OS was 54.7 months (95% CI: 47.5–NA) and 31.5 months (95% CI: 22.9–41.0) in the nonfrail ( n=452) and frail groups ( n=360), respectively ( P<0.001). The 3-year OS rates were (63.2 ± 3.2) % and (46.4 ± 3.6) % for the non-frail and frail groups, with 5-year OS rates of (49.9 ± 4.7) % and (32.0 ± 4.3) %, respectively ( P<0.001). ③Subgroup analysis revealed that nonfrail patients demonstrated significantly higher 3-year OS rates than frail patients in both the IPSS-M low-risk and very high-risk groups (all P<0.05). Similarly, nonfrail patients demonstrated superior 3-year OS rates compared with frail patients in the IPSS-R very low-risk, low-risk, and high-risk groups (all P<0.05). ④Among patients receiving hypomethylating agent therapy, the overall response rate was significantly higher in the non-frail group than in the frail group (86.7% vs 64.6%, P=0.007). Moreover, the frail group experienced higher rates of treatment-related adverse events, including febrile neutropenia (67.1% vs 47.4%, P=0.016) and liver function abnormalities (30.0% vs 14.5%, P=0.023), compared with the non-frail group. Conclusion:The FS-15 frailty score is a feasible and effective tool for assessing frailty in patients newly diagnosed with MDS in China and serves as a valuable prognostic indicator.
