[Objective] To study the molecular biological mechanism for a case of ABO blood group B subtype, and perform three-dimensional modeling of the mutant enzyme. [Methods] The ABO phenotype was identified by the tube method and microcolumn gel method; the ABO gene of the proband was detected by sequence-specific primer polymerase chain reaction (PCR-SSP), and the exon 6 and 7 of the ABO gene were sequenced and analyzed. Homologous modeling of Bw.03 glycosyltransferase (GT) was carried out by Modeller and analyzed by PyMOL2.5.0 software. [Results] The weakening B antigen was detected in the proband sample by forward typing, and anti-B antibody was detected by reverse typing. PCR-SSP detection showed B, O gene, and the sequencing results showed c.721 C>T mutation in exon 7 of the B gene, resulting in p. Arg 241 Trp. Compared with the wild type, the structure of Bw.03GT was partially changed, and the intermolecular force analysis showed that the original three hydrogen bonds at 241 position disappeared. [Conclusion] Blood group molecular biology examination is helpful for the accurate identification of ambiguous blood group. Homologous modeling more intuitively shows the key site for the weakening of Bw.03 GT activity. The intermolecular force analysis can explain the root cause of enzyme activity weakening.

This narrative review examines the challenges, strategies, and future directions in the development of young teachers within the pathophysiology departments of Chinese medical colleges. A thorough review of 49 studies published between 2013 and 2024 was carried out using PubMed, Web of Science, and various Chinese databases. The primary challenges identified include teaching innovation (cited in 84.2% of the studies), research pressure (91.2%), disciplinary characteristics (87.7%), and career development (80.7%). Medical schools have responded by enhancing training systems (94.7%), innovating teaching methods (93.0%), and bolstering research support (96.5%). Looking ahead, trends are shifting toward the application of new technologies, interdisciplinary integration, and international collaboration. The focus on cultivating young teachers is increasingly geared towards personalization and diversification, which are essential for advancing education in pathophysiology. High-quality young teachers are pivotal in raising teaching standards, fostering research innovation, and facilitating interdisciplinary exchanges. Based on these insights, we recommend several practical measures to enhance the quality of pathophysiology education in China. These include establishing comprehensive training programs that integrate teaching innovation and research skills; developing structured mentorship systems with clear pathways for career advancement; creating platforms that support technology-enhanced teaching and international collaboration; and implementing systematic evaluation mechanisms to assess teaching effectiveness. These targeted interventions will require a coordinated effort from department heads, educational institutions, and policymakers to ensure a sustained improvement in the quality of pathophysiology education.

Optimizing the management of medical service appointment is an important measure to enhance the patient′s medical experience and promote the high-quality development of hospitals. In 2022, a tertiary comprehensive hospital in Jiangsu Province focused on the demand for digital appointments, and carried out coordinated management of intelligent appointment for medical examination both inside and outside the hospital, online and offline. By constructing an intelligent examination appointment system, enriching appointment categories, exchanging appointment information, improving supporting services, and establishing appointment supervision mechanisms, this practice provided intelligent, personalized, and precise examination appointment services for patients in multi-campus hospitals and member units of medical group. The average waiting time of patients for CT, MRI, and ultrasound examinations in this hospital decreased from 7.43 h, 8.75 h, and 4.63 h in 2021 to 4.63 h, 4.72 h, and 2.18 h in 2023, respectively, as well as the average satisfaction rate of patients with examination appointments increased from 90.7% to 96.5%. The intelligent examination appointment management had achieved good results, which could provide references for other hospitals to optimize appointment of medical services.

Objective:To analyze the clinical application effects of different anesthesia maintenance methods in daytime pediatric sur-gery in oral maxillofacial surgery.Methods:80 children underwent anethesia for daytime surgery in oral maxillofacial region were en-rolled and divided into 2 groups(n=40).The maintenance dose of propofol was 2-3(mg·kg)/h in venous group,that was 3％to 4％sevofluranenas in opharyngeal airway-assisted inhalation group.The heart rate,mean arterial pressure,oxygen saturation,postoperative wake-up time and incidence of adverse reactions after the local anesthesia(T1),intraoperative(T2)and end-of-surgery(T3)were re-corded and compared between the 2 groups.Results:No statistical difference in heart rate change between the 2 groups at different time points(P＞0.05).The average arterial pressure decrease and the decrease of oxygen saturationin in the inhalation group were lower than those of the venous group(P＜0.01).The incidence of adverse events in the inhalation group were lower than that of the intravenous group(P＜0.05).Conclusion:Nasopharyngeal airway-assisted inhalation anesthesia has definite sedative effect in daytime pediatric pa-tients in oral maxillofacial surgery with less influence on the circulatory system and fewer adverse events.

Objective:To compare iodine nutritional status of different populations consuming iodized salt and non-iodized salt in iodine adequate areas, and to provide a basis for formulating iodine supplementation strategies.Methods:In October 2021, Luyi County in Henan Province was selected as an iodine adequate area consuming iodized salt, while Ningling County was selected as an iodine adequate area consuming non-iodized salt. Stratified by water iodine (50 - 59, 60 - 69, 70 - 79, 80 - 89, 90 - 100 μg/L), one village was selected from each layer. One hundred children aged 8 - 10, one hundred adults, and 20 pregnant women were selected from each village to collect their urine and salt samples for testing salt and urinary iodine, and their thyroid gland was measured by ultrasound.Results:A total of 600 salt samples in Luyi County were collected, with the coverage rate of iodized salt (99.8%, 599/600) and the consuming rate of qualified iodized salt (95.5%, 573/600). A total of 1 008 salt samples in Ningling County were collected, with the rate of non-iodized salt (93.8%, 946/1 008). The median urinary iodine of children in Luyi County ( n = 240) was higher than that in Ningling County ( n = 468, 305.0 vs 232.0 μg/L, Z = - 8.10, P < 0.001). There was no statistically significant difference in median urinary iodine between pregnant women in Luyi County ( n = 120) and Ningling County ( n = 53, 240.0 vs 236.0 μg/L, Z = - 1.02, P = 0.306). The median urinary iodine of adults in Luyi County ( n = 238) was higher than that in Ningling County ( n = 486, 289.0 vs 178.5 μg/L, Z = - 11.14, P < 0.001). Children's urinary iodine ( r s = 0.21, P = 0.001) in Luyi County and adults' urinary iodine ( r s = 0.17, P < 0001) in Ningling County were positively correlated with water iodine. There was no statistically significant difference in the incidence of thyroid enlargement in children between Luyi County (0.8%, 2/240) and Ningling County (0.4%, 2/468, χ 2 = 0.80, P = 0.586), but the incidence of thyroid nodules in children in Luyi County (11.2%, 27/240) was higher than that in Ningling County (1.7%, 8/468, χ 2 = 27.36, P < 0.001). The incidence of thyroid nodules in pregnant women in Luyi County (23.3%, 28/120) was lower than that in Ningling County (46.5%, 33/71, χ 2 = 10.99, P = 0.001). There was no statistically significant difference in the incidence of adult thyroid nodules between Luyi County and Ningling County (χ 2 = 0.86, P = 0.354), with a ratio of 29.6% (71/240) to 32.9% (160/486). Conclusions:Providing population with non-iodized salt in iodine adequate areas, the overall iodine nutrition is at an appropriate level. However, children consuming iodized salt in iodine adequate areas have high level of iodine nutrition, and it is necessary to consider supplying non-iodized salt or reducing the concentration of iodized salt. Pregnant women in iodine adequate area should maintain the current policy of supplying iodized salt unchanged.

Objective:To investigate the iodine nutritional status of key populations in iodine adequate areas in Henan Province, and provide a basis for timely adoption of targeted prevention and control measures and scientific formulation of iodine supplementation strategies in iodine adequate areas.Methods:From March to September 2022, a cross-sectional survey was conducted in 60 iodine adequate counties (cities, districts) in 13 provincial-level cities in Henan Province. Administrative villages with a median water iodine level of 40 - 100 μg/L within each county (city, district) were stratified by water iodine value (40 - 49, 50 - 59, 60 - 69, 70 - 79, 80 - 89, 90 - 100 μg/L). One administrative village was selected from each water iodine layer, and 40 non boarding students aged 8 - 10 years old (age balanced, half male and half female) and 20 pregnant women were selected from each administrative village to collect their household edible salt samples and once random urine sample for test salt iodine and urinary iodine contents; and the thyroid volume of children was measured.Results:A total of 12 203 samples of household edible salt were collected from children aged 8 - 10 years old, with a median salt iodine of 24.5 mg/kg, the iodized salt coverage rate was 85.3% (10 414/12 203), and the qualified iodized salt consumption rate was 77.1% (9 406/12 203). A total of 3 999 samples of household edible salt were collected from pregnant women, with a median salt iodine of 24.0 mg/kg, the iodized salt coverage rate was 84.2% (3 366/3 999), and the qualified iodized salt consumption rate was 74.5% (2 981/3 999). A total of 12 241 urine samples from children aged 8 - 10 years old were collected, with a median urinary iodine of 290.4 μg/L. A total of 4 084 urine samples from pregnant women were collectedd, with a median urinary iodine of 233.0 μg/L. The thyroid volume of 11 971 children was examined, and the rate of goiter was 2.1% (257/11 971). Stratified by water iodine content, the median urinary iodine levels of children in 40 - 59, 60 - 79, and 80 - 100 μg/L water iodine groups were 269.7, 298.0 and 308.0 μg/L, respectively, with a statistically significant difference between the groups ( H = 67.32, P < 0.001). The goiter rates of children were 2.2% (100/4 603), 2.1% (80/3 733), 2.1% (77/3 635), respectively, with no statistically significant difference between the groups (χ 2 = 0.03, P = 0.986). The median urinary iodine levels of pregnant women were 225.4, 243.1, 234.4 μg/L, respectively, with a statistically significant difference between the groups ( H = 10.96, P = 0.004). Conclusions:The iodine nutrition level of children in iodine adequate areas in Henan Province is at an excessively suitable level, and pregnant women's iodine nutrition is at an appropriate level. It is recommended to strengthen surveillance on the basis of maintaining current prevention and control measures, and adjust prevention and control measures in a timely manner according to changes in iodine nutrition in the population.
