OBJECTIVE: To analyze the phenotype and genotype of a neonate with Osteo-oto-hepato-enteric syndrome (O2HE) and review the literature. METHODS: A female neonate diagnosed with O2HE syndrome on December 13, 2024 at the First Affiliated Hospital of Zhengzhou University was selected as the study subject, and her clinical characteristics were analyzed, and pathogenic variants were explored by whole exome sequencing (WES). This study was approved by the Medical Ethics Committee of the Hospital (Ethics No.: 2025-KY-1038). RESULTS: The proband, a female infant, was delivered by Cesarean section at 36⁺¹ weeks of gestation. Five days after birth, she had developed severe diarrhea, mild cholestasis, sensorineural hearing loss, and growth retardation. WES revealed that she has harbored novel compound heterozygous variants c.512delA (p.Lys171Serfs*64) and c.698C>A (p.Thr233Asn) of the UNC45A gene, which were inherited from her mother and father, respectively. A total of 8 English papers were retrieved, which involved 16 patients from 14 families. Combined with our case, the 17 patients included 13 (76.5%) females and 4 (23.5%) males. Four patients (23.5%) had consanguineous parents. One case was excluded from further genetic analysis due to co-morbidity with other genetic variants. The primary clinical features included diarrhea (87.5%), cholestasis (81.3%), sensorineural hearing loss (31.3%), bone fragility (37.5%), and developmental delay (50.0%). Bi-allelic compound heterozygous mutations were identified in 12 patients (75.0%), and homozygous variants in 4 (25.0%). These included missense, nonsense, frameshift and deletional variants. The c.710T>C (p.Leu237Pro) variant was identified for 5 times, 3 of which were in homozygote forms. CONCLUSION O2HE syndrome should be suspected in cases with diarrhea, cholestasis, and hearing abnormalities during early postnatal period. Genetic testing facilitate early identification, genetic diagnosis and treatment.

ObjectiveThis paper aims to observe the role of Danlou tablet in treating coronary heart disease （CHD） with phlegm-stasis intermingling syndrome in minipigs by improving platelet function and explore the potential pharmacological mechanism of Danlou tablet in regulating platelet function by using proteomics technology. MethodsThirty Bama minipigs were randomly divided into a normal control group （6 pigs） and a high-fat diet group （24 pigs）. After 2 weeks of high-fat diet feeding， the high-fat diet group was randomly subdivided into a model group， an atorvastatin group （1 mg·kg^-1）， and Danlou tablet groups （0.6 g·kg^-1 and 0.3 g·kg^-1）. All groups continued to receive a high-fat diet for 8 weeks after the procedure. The normal control group was given a regular diet， underwent only coronary angiography， and did not receive an interventional injury procedure. The model group and each administration group were fed a high-fat diet. Two weeks later， they underwent a coronary angiography injury procedure. After the procedure， drugs were mixed into the feed every morning for 8 consecutive weeks， with the minipigs maintained on a continuous high-fat diet during this period. Quantitative proteomics technology was further used to study platelet proteins， and differential proteins were obtained by screening. Bioinformatics analysis was performed to analyze key regulatory proteins and biological pathways involved in the therapeutic effect of Danlou tablet on CHD with phlegm-stasis intermingling syndrome. ResultsCompared with the normal control group， the model group showed a significant increase in total cholesterol （TC）， triglyceride （TG）， high-density lipoprotein cholesterol （HDL-C）， and low-density lipoprotein cholesterol （LDL-C） of minipigs' serum （P<0.01）， a significant shortening in prothrombin time of （PT） （P<0.01）， a coagulation function index， and an increase in whole blood viscosity （P<0.01） and platelet aggregation rate （P<0.01）. Moreover， the platelet morphology was altered， and the contents of endothelin-1 （ET-1） and nitric oxide （NO） were significantly increased （P<0.01）. Hemodynamic parameters were obviously abnormal， including significantly decreased systolic blood pressure （SBP）， diastolic blood pressure （DBP）， mean arterial pressure （MAP）， left ventricular systolic pressure （LVSP）， and left ventricular maximal positive dp/dt （LV+dp/dt_max） （P<0.01）. Left ventricular maximal negative dp/dt （LV-dp/dt_max） was significantly increased （P<0.01）. Besides， there were myocardial cell hypertrophy， obvious edematous degeneration， massive interstitial inflammatory cell infiltration， high degree of fibrosis， and coronary endothelial atherosclerosis. TC and TG levels in minipigs' serum were significantly reduced in Danlou tablet groups with 0.6 g·kg^-1 and 0.3 g·kg^-1 （P<0.05， P<0.01）， compared with those in the model group. LDL-C was decreased in the Danlou tablet group with 0.6 g·kg^-1 （P<0.05）. The whole blood viscosity under low and high shear conditions was significantly reduced in the Danlou tablet group with 0.6 g·kg^-1 （P<0.05）. In groups with all doses of Danlou tablet， maximum aggregation rate （MAR） and average aggregation rate （AAR） were significantly decreased （P<0.05， P<0.01）， and platelets' morphological changes such as pseudopodia extension were reduced. ET-1 levels in the serum were significantly reduced. In the Danlou tablet group with 0.6 g·kg^-1， NO level in the serum was reduced （P<0.05）. In groups with all doses of Danlou tablet， DBP and MAP were significantly increased （P<0.05）. In the Danlou tablet group with 0.6 g·kg^-1， LVSP and LV+dp/dt_max were significantly increased （P<0.05， P<0.01）， and LV-dp/dt_max was significantly decreased （P<0.05）. In groups with all doses of Danlou tablet， edematous degeneration in myocardial tissue was milder， and coronary artery lesion degree was significantly alleviated. Compared with the normal control group， there were 94 differentially expressed proteins in the model group， including 81 up-regulated and 13 down-regulated proteins. Compared with the model group， the Danlou tablet group with 0.6 g·kg^-1 showed 174 differentially expressed proteins， including 100 up-regulated and 74 down-regulated proteins. A total of 30 proteins were reversed after Danlou tablet intervention. Bioinformatics analysis revealed that its pharmacological mechanism may exert anti-platelet activation， aggregation， and adhesion effects through biological pathways such as regulation of actin cytoskeleton， platelet activation pathway， Fcγ receptor-mediated phagocytosis， as well as proteins such as growth factor receptor-bound protein 2 （GRB2）， Ras-related C3 botulinum toxin substrate 2 （RAC2）， RAC1， and heat shock protein 90 alpha family class A member 1 （HSP90AA1）. ConclusionDanlou tablet can effectively reduce platelet activation and aggregation， exerting a good therapeutic effect on CHD with phlegm-stasis intermingling syndrome in minipigs. Its pharmacological mechanism may involve regulating biological pathways such as actin cytoskeleton and platelet activation pathway， as well as proteins like GRB2， RAC2， RAC1， and HSP90AA1， thereby exerting a pharmacological effect in anti-platelet activation， aggregation， and adhesion.

OBJECTIVE To evaluate the influence of pharmaceutical quality control on the efficiency and outcomes of standardized medication therapy management （MTM） services for patients with coronary heart disease by using Economic， Clinical and Humanistic Outcomes （ECHO） model. METHODS This study collected case data of coronary heart disease patients who received MTM services during January-March 2023 （pre-quality control implementation group， n＝96） and June-August 2023 （post-quality control implementation group， n＝164）. Using propensity score matching analysis， 80 patients were selected from each group. The study subsequently compared the economic， clinical， and humanistic outcome indicators of pharmaceutical services between the two matched groups. RESULTS There were no statistically significant differences in baseline data between the two groups after matching （P＞0.05）. Compared with pre-quality control implementation group， the daily treatment cost （16.26 yuan vs. 24.40 yuan， P＜0.001）， cost-effectiveness ratio [23.12 yuan/quality-adjusted life year （QALY） vs. 32.32 yuan/QALY， P＜0.001]， and the incidence of general adverse drug reactions （2.50% vs. 10.00%， P＝0.049） of post-quality control implementation group were decreased significantly； the utility value of the EuroQol Five-Dimensional Questionnaire （0.74± 0.06 vs. 0.71±0.07， P＝0.003）， the reduction in the number of medication related problems （1.0 vs. 0.5， P＜0.001）， the medication adherence score （[ 6.32±0.48） points vs. （6.10±0.37） points， P＝0.001]， and the satisfaction score （[ 92.56±1.52） points vs. （91.95±1.56） points， P＝0.013] all showed significant improvements. Neither group experienced serious adverse drug reactions. There was no statistically significant difference in the incidence of new adverse reactions between the two groups （1.25% vs. 3.75%， P＝0.310）. CONCLUSIONS Pharmaceutical quality control can improve the quality of pharmaceutical care， and the ECHO model can quantitatively evaluate the effect of MTM services， making pharmaceutical care better priced and more adaptable to social needs， thus being worthy of promotion.

Objective : To investigate the prevalence of negative emotions in hospitalized youth patients with type 2 diabetes(T2DM) and its correlation with coping strategies and psychological resilience. Methods : 141 youth T2DM patients who met the research standards were selected. Blood glucose related indicators, blood pressure, body mass index(BMI), diabetes chronic complications screening results and other data were collected. The basic information and disease related information questionnaire, self-rating depression scale(SDS), self-rating anxiety scale(SAS), diabetes distress scale(DDS), medical coping modes questionnaire(MCMQ) and Connor-Davidson resilience scale(CD-RISC) were completed. Results: Among 141 hospitalized youth T2DM patients, 37.6% were combined with depression, 32.6% were combined with anxiety, and 35.5% were combined with diabetic distress(DD). Univariate analysis showed that systolic blood pressure(P<0.01), educational level, and the form of hospitalization expenses(P<0.05) were significantly correlated with depression. Marital status(P<0.01), family residence, blood glucose monitoring methods, and the last fasting blood glucose(P<0.05) were significantly correlated with anxiety. BMI, whether it was first diagnosed or treated(P<0.01), gender, occupation, disease course, weekly blood glucose monitoring frequency, and the presence of chronic complications(P<0.05) were significantly correlated with DD. In multivariate analysis, systolic blood pressure(P<0.01), educational level, and the form of hospitalization expenses were significantly correlated with depression, marital status(P<0.05) was significantly correlated with anxiety; BMI and weekly blood glucose monitoring frequency(P<0.01) were significantly correlated with DD. SDS, SAS, total scores and dimensions of DDS were negatively correlated with the total score and dimensions of CD-RISC(rs=-0.182--0.467, P<0.05 or 0.01), and positively correlated with the yielding coping strategies(rs=0.177-0.271,P<0.05 or 0.01). SAS,total scores and dimensions of DDS were positively correlated with avoiding coping strategies(rs=0.237-0.419,P<0.05 or 0.01). The total and dimensions of CD-RISC were positively correlated with facing coping strategies(rs=0.215-0.349,P<0.05 or 0.01),and negatively correlated with yielding coping strategies(rs=-0.234--0.325,P<0.01). Conclusion More than 30% of hospitalized youth T2DM may experience negative emotions such as depression,anxiety,and DD. The occurrence of negative emotions in such patients may be related to disease management or socio-economic issues such as systolic blood pressure,educational level,hospitalization expenses,marital status,BMI,and frequency of blood glucose monitoring,as well as decreased psychological resilience and negative coping strategies.

Objective:To investigate the effect of human epidermal growth factor receptor 2 (HER2) on bladder cancer by regulating phosphoinositide 3-kinase (PI3K)-protein kinase B (Akt) signaling pathway via tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein epsilon peptide (YWHAE) and to examine its mechanism.Methods:The gene expression profiling interactive analysis (GEPIA) database was used to analyze HER2 expression in 408 bladder cancer tissues and 19 adjacent normal tissues. HER2 expression was then compared between 215 tumor protein 53 ( TP53) mutant and 193 TP53 non-mutant bladder cancer tissues. Tissue samples were obtained from patients who underwent surgical resection for bladder cancer in Tianjin Medical University General Hospital between June 2010 and March 2015. Immunohistochemistry and Western blotting were performed to validate HER2 and p53 protein expression, as well as analyze their correlation. Bladder cancer T24 cells were transfected with short hairpin RNA targeting HER2 (shHER2) control (shCon) or shHER2, designated as shCon and shHER2 groups. Bladder cancer UMUC3 cells were transfected with overexpression control (oeCon), HER2 overexpression (oeHER2), oeYWHAE, or short hairpin RNA targeting murine double minute 2 (MDM2) (shMDM2), and were designated as the oeCon, oeHER2, oeYWHAE and shMDM2 groups, respectively. UMUC3 cells were then treated with either 0.1% dimethyl sulfoxide or 100 mmol/L dihydrotestosterone and designated as the solvent control and dihydrotestosterone groups, respectively. Additionally, oeCon and oeYWHAE UMUC3 cells were treated with the PI3K inhibitor LY294002 (25 μmol/L), designated as the LY294002 and LY294002+oeYWHAE groups. On this basis, shHER2 was transfected into the oeCon and oeYWHAE groups, which were then designated as the shHER2-2 and shHER2-2+oeYWHAE groups. The relative expression levels of HER2, YWHAE mRNA, and HER2, p53, YWHAE, MDM2, phosphorylated Akt (p-Akt), and Akt proteins were determined using quantitative reverse transcription PCR and Western blotting. Cell Counting Kit-8, Transwell, and wound-healing assays were performed to evaluate the impact of HER2 on the proliferation, invasion, and migration of bladder cancer cells. Mass spectrometry and co-immunoprecipitation assays were performed to confirm the interaction between YWHAE and HER2, and immunofluorescence was used to detect p53 expression. BALB/c nude mice were subcutaneously injected with 5×10 6 UMUC3 cells in the scapular region. According to the random number table method, they were divided into negative the control group and the transfection group, with 3 mice in each group, and transfected with oeCon and oeHER2, respectively. Tumor volume and weight were measured and calculated, and HER2 and p53 protein expression in bladder cancer tissues was validated by immunohistochemistry and Western blotting. Independent sample t test or Mann-Whitney U test was used to compare the two groups. One-way analysis of variance or Kruskal-Wallis test was used for comparison of multiple groups. Results:GEPIA database analysis demonstrated significantly higher levels of HER2 expression in bladder cancer tissues and in TP53 mutant bladder cancers compared with adjacent normal tissues (both P<0.01). HER2 expression was inversely correlated with p53 expression ( r=?0.6). Immunohistochemistry and Western blotting confirmed that p53 expression level in the bladder cancer tissues (5.32±0.11) was higher than that in the adjacent normal tissues (2.00±0.01), while HER2 expression level in the bladder cancer tissues (1.13±0.02) was lower than that in the adjacent normal tissues (6.20±0.06) (both P<0.01). HER2 mRNA and protein expression, absorbance at 450 nm wavelength ( A450) values, and cell invasion number and cell migration distance in the shHER2 group were all lower than those in the shCon group [0.25±0.01 vs 1.00±0.05, 1.00± 0.01 vs 3.26±0.09, 1.36±0.04 vs 1.65±0.06, (107.00±5.51) vs (202.70±11.61) cells, and (298.70±6.94) vs (454.30±7.84) μm] ( P<0.05, 0.01). HER2 mRNA and protein expression, absorbance ( A450) values, and cell invasion number and cell migration distance in the oeHER2 group were all higher than those in the oeCon group [0.78±0.02 vs 0.46±0.01, 2.05±0.02 vs 1.00±0.00, 1.23±0.06 vs 0.78±0.03, (136.30±5.24) vs (59.00±5.51) cells, and (153.70±7.27) vs (66.33±33.84) μm] ( P<0.05, 0.01). HER2 protein expression level in the dihydrotestosterone group was higher than that in the solvent control (1.83±0.19 vs 1.00±0.00), while p53 protein expression level in the dihydrotestosterone group was lower than that in the solvent control group (1.10±0.10 vs 1.53±0.15) (both P<0.01). The differentially expressed protein between the dihydrotestosterone group and solvent control group was YWHAE. The expression levels of YWHAE mRNA and protein in the dihydrotestosterone group (1.10±0.12 and 3.05±0.03) were higher than those in the solvent control group (0.30±0.12 and 1.00±0.00) (both P<0.01). YWHAE protein expression level in the oeHER2 group was higher than that in the oeCon group (1.37±0.08 vs 1.00±0.00) ( P<0.01) and YWHAE expression level in the bladder cancer tissues was higher than that in the adjacent normal tissues ( P<0.01). YWHAE expression positively correlated with HER2 expression ( r=0.4). Co-immunoprecipitation confirmed direct binding between HER2 and YWHAE. Overexpression of YWHAE significantly reduced p53 expression. The relative expression level of MDM2 protein in the oeYWHAE group (2.73±0.09) was lower than that in the oeCon group (3.43±0.12) ( P<0.01). The relative expression level of MDM2 protein in the shMDM2 group (1.00±0.00) was lower than that in the oeYWHAE group, and the relative expression level of p53 protein (2.00±0.00) was higher than that in the oeYWHAE group (1.07±0.07) (both P<0.01). The relative expression levels of YWHAE and p-Akt protein in the oeYWHAE group (1.23±0.09, 3.00±0.06) were higher than those in the oeCon group (1.00±0.00, 1.13±0.03) ( P<0.05, 0.01). The relative expression level of p-Akt protein in LY294002 group (2.20±0.06) was lower than that in the oeCon group (3.30±0.10), and the relative expression level of p53 protein (2.10±0.06) was higher than that in the oeCon group (1.00±0.00) (both P<0.01). The relative expression level of p-Akt protein in LY294002+oeYWHAE group (2.00±0.06) was lower than that in the oeYWHAE group (3.53±0.14), and the relative expression level of p53 protein (2.10±0.06) was higher than that in the oeYWHAE group (1.00±0.06) (both P<0.01). The relative expression levels levels of YWHAE, p-Akt and MDM2 protein in the shHER2-2 group (1.60±0.15, 1.70±0.06, 0.80±0.06) were lower than those in the oeCon group (2.30±0.06, 2.30±0.06, 1.13±0.09), and the relative expression level of p53 protein (1.83±0.12) was higher than that in the oeCon group (1.00±0.00) ( P<0.05, 0.01). The relative expression level of YWHAE protein in the shHER2-2+oeYWHAE group (2.00±0.06) was lower than that in the oeCon group ( P<0.01), and the relative expression levels of MDM2 and p53 protein (2.63±0.15, 1.13±0.03) were higher than those in the oeCon group ( P<0.05, 0.01). The tumor volume, tumor weight, and relative expression levels of HER2, YWHAE, p-Akt, and MDM2 proteins on day 28 in the transfection group [(5 133.0±185.6) mm 3, (0.65±0.12) g, 2.23±0.02, 4.00±0.12, 3.33±0.06 and 2.24±0.02] were higher than those in the negative control group [(2 633.0±88.2) mm 3, (0.33±0.07) g, 0.98±0.02, 1.27±0.03, 1.29±0.02 and 1.46±0.06] (all P<0.01). The relative expression level of p53 protein (1.21±0.04) was lower than that in the negative control group (3.29±0.04) ( P<0.01). Conclusions:HER2 may promote the malignant progression of bladder cancer by regulating the PI3K-Akt pathway via YWHAE, thereby facilitating MDM2 nuclear translocation and p53 degradation. This ultimately enhances the proliferative, migratory, and invasive capacities of bladder cancer cells.

The oral glucose growth hormone suppression test is commonly used in the clinical diagnosis of acromegaly, but its results can be influenced by a variety of factors. This case report discusses a patient with a pituitary tumor and concurrent liver cirrhosis, highlighting the complexities in interpreting test results under such conditions. The patient, a 54-year-old male, presented with blurred vision as his primary complaint. Notably, the physical examination revealed no changes in facial features, no enlargement of hands or feet, and no other symptoms typically associated with acromegaly, which might otherwise suggest excessive growth hormone activity. Magnetic Resonance Imaging (MRI) of the pituitary gland indicated that the gland was within normal size parameters, but a small low-intensity lesion mea-suring approximately 3 mm×2 mm identified. This finding was consistent with a pituitary microadenoma. The patient's fasting growth hormone levels were significantly elevated at 8.470 μg/L, compared with the normal range of less than 2.47 μg/L. Conversely, fasting insulin-like growth factor-1 (IGF-1) levels were notably low, recorded at 41 and 52 μg/L, whereas the normal range for a person of his age was between 87 and 234 μg/L. Other pituitary hormones, including those regulating the thyroid, adrenal cortex, and sex hormones, were found to be within normal ranges. Despite this, during the glucose growth hormone suppression test, an abnormal elevation of growth hormone was observed. To investigate further, the patient was administered branched-chain amino acids, and the suppression test was repeated. However, the abnormal elevation of growth hormone persisted, indicating a failure to normalize the response. Given the patient's lack of clinical signs typically associated with elevated growth hormone secretion, the history of liver cirrhosis became a significant consideration. The disparity between elevated growth hormone levels and reduced IGF-1 levels suggested that the pituitary lesion was a non-functional adenoma rather than a source of excess hormone production. Consequently, it was concluded that the abnormal response of growth hormone to the glucose suppression test was likely related to the patient's liver cirrhosis. In addition to chronic liver disease, various other conditions could influence the results of the oral glucose tolerance growth hormone suppression test. According to the literature, factors such as puberty, diabetes, anorexia nervosa, and protein malnutrition could also affect test outcomes. These conditions could cause similar abnormalities in growth hormone dynamics, complicating the diagnosis. Therefore, clinicians must be vigilant and consider these potential influences when interpreting test results.For an accurate diagnosis of acromegaly, it is essential to combine clinical symptoms, detailed medical history, and imaging studies. The presence of conditions like liver cirrhosis should prompt careful interpretation of the test results, ensuring that other contributing factors are not overlooked. This comprehensive approach is crucial to avoid misdiagnosis and to ensure that appropriate treatment strategies are implemented based on a thorough understanding of the patient's overall health status.

Purpose To investigate the correlation between two autophagy-related proteins,JMY and WHAMM,and autophagic dysfunction and prognosis in gliomas.Methods A total of 113 cases of diffuse gliomas and 14 control brain tissues were collected.The expression of JMY,WHAMM,and autophagy-related markers were evaluated using the EnVision two-step method of immunohistochemistry.Correlations between the expression of JMY and WHAMM and clinicopathological features,prognosis,and autophagy markers were analyzed.Results The high expression rates of JMY and WHAMM in control brain tissue were significantly higher than those in diffuse gliomas.The expressions of JMY and WHAMM were associated with pathological grade and age.Compared with low-grade gliomas(LGG),high-grade gliomas(HGG)showed significantly lower high-expression rates of JMY and WHAMM.Patients with low expres-sion of JMY and WHAMM had shorter overall survival than those with high expression.Cox regression analysis indica-ted that the high pathological grade and low expression of JMY were independent prognostic risk factors.The expression profiles of autophagy markers suggested reduced autophagic activity in HGGs,and JMY expression was positively corre-lated with autophagy markers.Conclusion The high expression rates of JMY and WHAMM are significantly lower in HGGs compared to LGGs.JMY and WHAMM may serve as potential molecular markers for the prognostic evaluation of diffuse gliomas.

Objective:To determine the prevalence of self-reported food allergies among children in the grasslands of North China and to analyze its associated risk factors.Methods:In this study, a cross-sectional epidemiological survey method was used to select children under 14 years old by multi-stage, stratified and random cluster sampling in the grassland ecological area of Zhangbei County, Hebei Province, China from May to July 2018. Face-to-face questionnaires were administered to gather food allergy-related information from the participants. Multivariate logistic regression analysis was used to analyze the risk factors associated with self-reported food allergy.Results:A total of 2 086 children completed the survey. The prevalence of self-reported food allergies was 22.0%(459/2 086). The prevalence of multiple food allergies (≥3 types) was 3.1%(64/2 086) versus 16.3% (341/2 086) for a single food allergy among all children. Mango allergy (6.1%, 127/2 086) was the most common, followed by peach allergy (4.1%, 85/2 086). Children who reported food allergies had a significantly higher prevalence of all 4 atopic disorders (eczema, asthma, allergic rhinitis, and allergic conjunctivitis than those without food allergies(35.73% vs. 20.65%, 5.88% vs. 2.77%, 17.86% vs. 7.38%, 16.78% vs. 10.45%, χ2 =44.663 1, 10.434 3, 45.038 3, 13.728 4, all P<0.001).Significantly associated risk factors of food allergy were found to be pollen allergy ( OR: 2.29; 95% CI: 1.80-2.92) and drug allergy ( OR: 1.53; 95% CI: 1.12-2.09). Conclusions:The prevalence of self-reported food allergies among children in the Zhangbei County area of the North China Grassland was relatively high. Pollen allergy and drug allergy are major risk factors.
