Objective To study the dynamic changes in the secretion of neurotransmitters glutamic acid(Glu)and γ-aminobutyric acid(GABA)in the central auditory brain area,in order to explore the effects of sodium salicy-late on different locations of the auditory pathway.Methods A total of 126 SD rats were injected intraperitoneally with salicylate,and were divided into 10 groups including injection groups for 1,2,4,8,and 24 hours,chronic in-jection groups for 3,7,and 14 days,and chronic recovery groups for 21 and 28 days with 6 rats in each group,as well as their corresponding blank control groups.Rats in each group were anesthetized and materials were collected for further use.High-performance liquid chromatography(HPLC)was performed to detect and compare the dynam-ic changes in the levels of Glu and GABA in the auditory cortex,inferior colliculus,cochlear nucleus,and hippocam-pus of the auditory center of rats in each group at different time points.Results Compared with the control group,within 24 hours of acute injection of salicylate,the Glu content in the auditory cortex reached the peak in 1 hour,and the hippocampus reached the peak at the 4th hour after injection,and then decreased slowly.The GABA con-tent in the four brain regions showed a slow upward trend in the chronic injection period,reached the peak on the 7th day,decreased and approached normal level on the 14th day,and basically returned to the normal level in the re-covery period.Conclusion These findings indicate that salicylate has a certain short-term excitatory and stimulating effect on the central auditory system.Under the mechanism of central plasticity,after long-term injection of salicy-late,the release of neurotransmitters reaches a new excitation/inhibition balance in the central area.Glu and GABA may each play a different role that may ultimately lead to the development of tinnitus.

Objective To investigate the current status of emotional competence among nursing interns in tertiary grade A hospitals in Weifang City and explore influencing factors,providing a reference for implementing interventions to enhance emo-tional competence.Methods A convenience sampling method was used to select 522 nursing interns from three tertiary grade A hospitals in Weifang City from February 2024 to February 2025 as the study subjects.Results The total score of the emotional domain ability evaluation scale for nursing interns was(106.93±17.94)points,the score of professional belief perception ability was(30.16±5.28)points,the score of professional connotation comprehension ability was(25.38±5.29)points,the score of professional value evaluation ability was(30.74±4.96)points,and the score of professional value internalization ability was(20.66±4.16)points.Whether the nursing interns are competent in nursing work,the attitude of clinical nursing staff,patients and their families towards the nursing interns,and whether they have received emotional domain education training are the main influencing factors of the emotional domain ability of nursing interns(P＜0.05).Conclusion Nursing interns at Weifang's ter-tiary Grade A hospitals demonstrate sound development in emotional competence.To further enhance this capacity,a coordinated approach encompassing education,clinical training environment,evaluation systems,emotional support,and policy guidance should be implemented.This will establish a diversified and systematic emotional competence cultivation framework to achieve sustained imrovement in nursing quality.

Objective:To establish and validate the prediction model for bone marrow metastasis (BMM) in malignant tumors by screening out laboratory multiparameters.Methods:This case-control study collected 444 cases of malignant tumor patients who were hospitalized in the First Hospital of Jilin University from March 2018 to March 2024, including 243 cases for model establishment set and 201 cases for model validation set. The model establishment set was divided into BMM positive group (81 cases) and BMM negative group (162 cases), and the model validation set was divided into positive group (67 cases) and a negative group (134 cases). We collected patients′ clinical information such as gender, age, clinical diagnosis, and results of 47 laboratory tests including routine blood analysis, coagulation, liver function, tumor markers, potassium, sodium, chloride, and calcium ion tests, bone marrow morphology, and bone marrow biopsy. BMM was taken as the outcome event, differencial variables were analyzed using inter group comparisons, the correlation among parameters was analyzed using Pearson correlation analysis, the risk factors for BMM were analyzed using multivariate conditional logistic regression analysis, to establish logistic model, followed by efficiency evaluation on BMM predictive model using receiver operating characteristic (ROC) curves.Results:In the model establishment set, Pearson correlation analysis of 28 parameters that differed between the BMM positive and negative groups revealed that the correlation coefficients of 17 parameters, including mean platelet volume (MPV), hematocrit (HCT), hemoglobin (HGB), and prothrombin time (PT), were no more than 0.6 ( P<0.05). Further multivariate conditional logistic regression analysis demonstrated that MPV, HGB, HCT, PT, red cell distribution width (RDW), platelet count (PLT), alkaline phosphatase (ALP), chloride (Cl -), and mean erythrocyte hemoglobin concentration (MCHC) were the risk factors of BMM occurence in malignancy [MPV ( OR=9.929, 95% CI 2.688-71.335), HCT ( OR=8.232, 95% CI 6.223-9.841), HGB ( OR=4.300, 95% CI 1.947-16.577), PT ( OR=3.738, 95% CI 1.359-11.666), RDW ( OR=1.995, 95% CI 1.275-3.807), ALP ( OR=1.025, 95% CI 1.012-1.045), PLT ( OR=1.014, 95% CI 1.002-1.031), MCHC ( OR=0.724, 95% CI 0.523-0.880) and Cl -( OR=0.703, 95% CI 0.472-0.967)]. In the model establishment set, combiation of risk factors provided an AUC of 0.943 (95% CI 0.898-0.987, P<0.001), a sensitivity of 86.3%, and a specificity of 89.2% for BMM prediction. In the model validation set, the AUC was 0.924 (95% CI 0.854-0.960, P<0.001), with a sensitivity and specificity of 86.7% and 83.8%, respectively. Conclusion:This study built and validated a multiple-parameter model for BMM, which may facilitate the timely detection of BMM and provide reference for decision making of bone marrow aspiration.

Nonalcoholic fatty liver disease (NAFLD) is currently the most common chronic liver disease,with a prevalence of about 29.2％ in China.A large number of clinical studies have shown that NAFLD is closely related to cardiovascular-related metabolic diseases such as obesity,dyslipidemia,diabetes mellitus,hypertension,etc.,and NAFLD is an independent risk factor for atherosclerotic cardiovascular disease (ASCVD),and cardiovascular disease is the leading cause of death in patients with NAFLD.This article reviews the relationship between NAFLD and metabolic dysfunction-associated fatty liver disease (MAFLD) with ASCVD and related metabolic diseases,and discusses the related pathophysiological mechanisms such as insulin resistance,oxidative stress,and inflammation,aiming to provide practical recommendations for reducing the risk of NAFLD-associated cardiovascular disease.

By reviewing ancient materia medica， prescription and medical books， combined with modern literature， the paper made textual research on the name， origin， producing area， quality evaluation， harvesting and processing methods of Angelicae Pubescentis Radix and Notopterygii Rhizoma et Radix， so as to provide a basis for the selection and use of these two herbs in the development of famous classical formulas. Through textual research， it can be found that Angelicae Pubescentis Radix and Notopterygii Rhizoma et Radix were mixed together in the early history of China， but the distinction was first made during the Southern and Northern dynasties， and since then there have been constant controversies， and it is not until contemporary times that they are distinguished clearly. In the past dynasties， Duhuo and Qianghuo were used as the rectification of names， some aliases and trade names were also seen. Angelica biserrata is the mainstream origin of Angelicae Pubescentis Radix in the past dynasties， and there are many plants belonging to Angelica， Heracleum and Aralia， which are also used as this medicine. However， the origin of Notopterygii Rhizoma et Radix used in the past dynasties is mostly Notopterygium incisum or N. franchetii， which is relatively uniform. The producing areas of Angelicae Pubescentis Radix and Notopterygii Rhizoma et Radix are mostly concentrated in the western and northwestern regions of China， among which Angelicae Pubescentis Radix is mainly produced in Hubei， Chongqing， Sichuan， Shaanxi and other places， and the border area between Hubei and Chongqing is the geo-authentic area. Notopterygii Rhizoma et Radix is mainly produced in Sichuan， Gansu， Qinghai， Shaanxi and others with the western and northern Sichuan and southern Gansu as the geo-authentic areas. Angelicae Pubescentis Radix and Notopterygii Rhizoma et Radix in the past dynasties were harvested in spring and autumn， especially in February and August of the lunar calendar. Angelicae Pubescentis Radix with strong main roots， few branches， firm texture and strong aroma is superior， and Notopterygii Rhizoma et Radix with strong rhizomes， tightly raised knots， purple-brown skin， tight cross-section， strong aroma and silkworm-like shape is superior. The processing methods of Angelicae Pubescentis Radix and Notopterygii Rhizoma et Radix are mostly cut after cutting the reeds， and the raw product is used as medicine. Based on the above research results， it is recommended that the roots of A. biserrata should be used for Angelicae Pubescentis Radix and the roots of N. incisum should be used for Notopterygii Rhizoma et Radix in the development of famous classical formulas， and raw products should be used in the formulas that do not specify processing requirements.

Objective:To analyze the vaginal microecological status of vaginitis population and non-vaginitis population of gynecological female outpatients.Methods:A total of 30 265 women who visited the gynecological outpatient clinic of Beijing Obstetrics and Gynecology Hospital from December 2018 to December 2020 completed vaginal microecological examination. After removing the follow-up patients, 23 181 women were divided into group with symptoms and signs of vaginitis (6 697 cases) and group without symptoms and signs of vaginitis (16 484 cases), according to whether the women with symptoms and signs of vaginitis or not. And the vaginal microecological status of the two groups was compared and analyzed.Results:(1) The total detection rate of vaginitis in the initial women was 34.87% (8 083/23 181), of which 46.10% (3 087/6 697) in group with symptoms and signs of vaginitis and 30.31% (4 996/16 484) in group without symptoms and signs of vaginitis, nearly 1/3 of the gynecological outpatients without signs and symptoms of vaginitis had vaginitis. (2) Among the types of simple vaginitis, vulvovaginal candidiasis (VVC) was the most frequent in group with symptoms and signs of vaginitis (16.01%, 1 072/6 697), followed by aerobic vaginitis (AV; 12.83%, 859/6 697), with significant differences compared with group without symptoms and signs of vaginitis (all P<0.001). There were no statistical differences between the two groups of bacterial vaginosis (BV) and trichomonal vaginitis (TV), indicating that BV and TV were more likely to be neglected (all P>0.05). (3) The proportion of various combinations of vaginitis among 2 632 cases of mixed vaginitis were, in descending order: BV+AV, VVC+AV, BV+AV+VVC, AV+TV, AV+TV+BV, BV+VVC. (4) Microecological analysis of 15 098 cases diagnosed with non-vaginitis had normal flora (including those with normal flora and those with normal flora but decreased function) in 14 013 cases (92.81%, 14 013/15 098), abnormal flora in 429 cases (2.84%, 429/15 098) and the BV intermediate in 656 cases (4.34%, 656/15 098); this indicated that the vast majority of the microecological tests were normal in the vaginal microbiota of those without vaginitis. Conclusions:Microecological examination could diagnose multiple pathogenic infections at once, and is especially important as a guide for the definitive diagnosis of mixed vaginitis and vaginitis with atypical clinical symptoms. Vaginal infections such as BV and TV that are easily overlooked should be concerned.

Objective:To seek the effect of group education under the BOPPPS model(bridge-in, objective, pre-assessment, participatory learning, post-assessment, summary) on the breastfeeding competency of first gestation women, to improve the breastfeeding competency of first gestation women and promote the realization of postpartum breastfeeding.Methods:Eighty-one first gestation women were chosen from the gestation class of the First Affiliated Hospital of Shanxi Medical University, the quasi-experimental research method was adopted, 40 women from January to February 2022 were involved in the control group and 41 women from May to June 2022 were involved in the intervention group. The control group was assigned common education, while the intervention group was assigned group education based on BOPPPS model. Breastfeeding Competency Scale (BCS) and breastfeeding family support questionnaire were used to compare breastfeeding competency and family support level of the two groups before and after intervention, and the skin contact rate at 1 hour after delivery and the pure breastfeeding rate at 42 days after delivery were compared between the two groups.Results:Before intervention, there was no significant difference in breastfeeding competency and family support level between the two groups (all P>0.05). After 4 weeks of intervention, the scores of breastfeeding competency and family support were (147.59 ± 13.50), (3.16 ± 0.18) points in the intervention group, more than those in the control group (125.48 ± 16.87), (2.87 ± 0.22) points, the differences were statistically significant between the two groups ( t=-6.52, -6.30, both P<0.05). The skin contact rate at 1 hour after delivery and the pure breastfeeding rate at 42 days postpartum were 75.6%(31/41), 53.7%(22/41) in the intervention group, more than those in the control group 52.5%(21/40), 30.0%(12/40), the differences were statistically significant between the two groups ( χ 2=4.71, 4.65, both P<0.05). Conclusions:Group education based on BOPPPS model can improve the level of breastfeeding competency and family support of gestation women. It increases the skin contact rate, and plays a good role in promoting the increase of pure breastfeeding rate.
